The present invention relates to the creation of means of refrigeration storage, such as refrigerators and freezers to store food and other perishable goods. Among other applications of the present invention can be specified on the storage of chemicals, and medical or biological samples. The invention may also find application in mobile versions, for example during transportation or storage of perishable goods.

The invention develops and complements the various features and details of international application no PCT/GB00/03521 (publication WO 01/20237) the author of the invention of this application. The invention also develops the ideas of invention the UK No. 0106164.7 (publication GB 2367353), on the basis of which the applicant of the present application, claims, including priority. As indicated in the descriptions of the above publications, the present invention can be used to store any products in a cooling medium, for example in autorefrigerators. Therefore, the term "cooling chamber" should be interpreted in a broad sense, which includes in addition to the fixed household refrigerators refrigerators for industrial and scientific applications, and mobile refrigeration chamber. However, in this description I will be talking specifically about domestic or commercially you usaamah electric cooling chambers for storing food.

The advantages of storing food and other perishable products under refrigerated conditions and division known for a long time: cooling prevents damage to such products, the separation of the products helps to avoid cross-contamination. Accordingly, modern refrigerating chamber, such as refrigerators and freezers, are usually divided into compartments (compartments)so that the user can store different types of products in different departments, although this division is often ineffective. Before all such refrigerating chambers advanced the goal of achieving maximum energy efficiency.

Considering the invention was created amid the usual refrigerating chambers, most of which contain one or more vertical cabinets, each of which with its front side provided with a hinged door with a vertical seal. Virtually the entire internal volume of the Cabinet is a useful volume for storage, which is usually divided shelves or drawers for placing products. Opening door provides access to all shelves or drawers of the Cabinet.

Refrigeration unit creates a refrigeration Cabinet closed convective flow in which the air cooled by the refrigeration unit is lowered to the base of Jolo is safe Cabinet and, absorbing heat during the downward movement, is heated and rises again to a refrigerating unit, where it is again cooled. Can also be provided with forced air circulation by means of a fan located in the refrigeration Cabinet or connected with him. Shelves or drawers are usually made of wire, in order to provide low resistance to air circulation.

Vertical refrigerators and freezers are often combined and sold as a single unit, in which the refrigerator is the upper section of the Cabinet and freezer - bottom section, or Vice versa. As in these two sections require different temperature, then they are divided by a solid dividing wall, and each section has its own door and a refrigerating unit, usually in the form of the evaporator.

A household refrigerator with freezer usually has only one compressor, and the evaporator of the refrigeration section sequentially connected to the evaporator in the freezer section. In this case, the regulation and the temperature measurement is usually carried out only in the section of the refrigerator. If temperature control is required in both sections, the evaporators are included in parallel and are supplied with the respective solenoid valves and switches temperature is, providing on/off cooling in each section. But in any case, the temperature in the respective sections cannot be duplicated: one section is used for cooling, so it is isolated to a lesser extent than the other, and its temperature can be adjusted in the temperature range above zero Celsius, and the other section is used for freezing, so it is isolated to a greater extent than the first, and its temperature can be adjusted (if such regulation is generally available in the range of temperature below zero Celsius. Neither of the two sections cannot perform the function of another.

Publication WO 01/20237 devoted serious problem concerning vertical refrigerators and freezers, namely vertical door which when open allows cold air to freely enter from a refrigeration Cabinet, being replaced by warm ambient air within the upper part. This sudden influx of ambient air into the refrigerated Cabinet leads to an increase in its internal temperature, and, consequently, to increased energy consumption because of the need to compensate for this temperature increase operation of the refrigerating unit. The flow inside the ambient air carries with it the possibility of contamination of the contents of the refrigeration Cabinet through the air, and with the holding in this humidity leads to condensation and deposition of frost (ice) in the closet. These problems are exacerbated by the stronger, the more open the refrigerated Cabinet, particularly for commercial equipment.

In refrigerators and freezers with a vertical door above disadvantages of vertical seals mean that leak cold air and the inflow of warm air can occur even with a closed door. Being more dense than warm air, the coldest air accumulates at the bottom of the refrigerated Cabinet and pushes the seal, so that in the absence of a perfect seal between the door and the Cabinet, the air will go out.

In the present invention and in the publication WO 01/20237 also addresses the problems inherent in the well-known freezers, whose open top of the Cabinet is normally closed opening up the lid, hinged horizontally hinged. Such freezers inconvenient and uneconomical for the space, as it does not allow you to use the space directly above the freezer, which should be left free so that you can open the lid. In addition, the cover cannot be left any objects. Even if, instead of opening up the lid uses a sliding lid, the lid is inconvenient to leave any objects. It is also well known that in large freezers with cap is th hinges access their content is very difficult, because the user must bend down (bend down) and move a lot of heavy and very cold items in order to reach the object at the bottom of the freezer compartment.

And, finally, in the present invention and in the publication WO 01/20237 addresses the problem of separating different types of food products or other perishable goods to avoid cross-contamination. In conventional refrigerators to often prevents separation of the products used in these cameras the principle of convection and/or forced circulation. Mainly open baskets or shelves that are designed to provide convective air circulation between departments, promote the circulation of moisture, enzymes and harmful bacteria. In addition, any liquid flowing from the container for food products, such as juice, derived from raw meat, not delayed open baskets or shelves.

The prior art relating to this invention, presents not only the usual refrigerating chambers in the form of a vertical refrigerators and freezers with lid hinges. For example, has long been known for the idea of separation of the refrigerator compartment, each of which has its own door or cover. Examples of implementation of this idea disclosed in the patents GB 602590, GB 581121 and GB 579071, which describes the fridge in a Cabinet.

In these publications the front of the Cabinet has many rectangular holes for the introduction of drawers. Each drawer has a front panel, larger than the corresponding hole, so around the lap joints formed vertical seal when the drawer is in the closed (retracted) position. Drawers and their contents are cooled using a refrigeration unit that circulates the cooled air in the Cabinet due to convection, which is common with the previously described types of refrigerators. To facilitate circulation of air through all the drawers they have open top and a hole at the bottom. In addition, the drawers are stepped in such a way that those boxes that are closer to the top of the fridge, go back to a smaller distance than the lower drawers, so that the rear part of each box is opened for exposure going down stream of the cooled air from the refrigeration unit.

Despite the fact that at the same time you want to open (forward) only one drawer openings allow free flow through the open crate cold air, which is replaced by warm and humid ambient air, which then reduces the energy efficiency of the refrigerator and increases the likelihood of cross-contamination. In fact, when a drawer is opened, the cold air in the Cabinet above the level of this box will leak out, which leads to the suction of ambient air in the Cabinet. Moreover, the existence of drawers contributes to the inflow of ambient air into the inner space of the refrigerator, since the opening they act as pistons, inlet ambient air into the interior of the cooling body. After receipt in the fridge warm air can circulate inside it as freely as cold air, which ought to be there.

Even in the closed state of the refrigerator accumulation of cold air in the lower part of the Cabinet will create increased pressure on the vertical seal the bottom of a drawer, which increases the probability of leakage in case of a defect of the seal.

Another example of a refrigerator of the type specified above is disclosed in UK patent GB 602329. Disclosed in this patent refrigerator are also not spared from many of the problems mentioned above, however, the greatest interest is that the cooled inner space of the refrigerator is provided a single drawer with insulated side walls and base. Unlike the previously described variants, the side walls and base are solid, but not per aerovane, so that air cannot flow through them. When the drawer is closed, the horizontal element inside the Cabinet is combined with a box to create a branch, and the horizontal element is a cover for the drawer. Received the Department is equipped with its own cooling coils located directly below the horizontal element.

In the mentioned patent provides very few details about the seal that is formed between a drawer and a horizontal element, except that the horizontal element has a protruding rear end with an offset region, which provides a tight fit against the rear wall of a drawer. Nothing is said regarding the joint with a horizontal element, apart from the General statement that the drawer in the closed position adapted to "pretty tight" to the horizontal element. From this we can only conclude that a drawer and a horizontal element adjacent to each other. Despite the fact that it will impede the flow of air in a drawer and the output of the air out of it, this does not create a tight seal. As this seal is not a vapor barrier, then there is a possibility of ice even in a closed floor the position of the box.

Describes the construction of a drawer creates a unit that can be installed in a temperature different from the main image, the total temperature in the rest of the fridge. In particular, it is envisaged that this drawer can serve as a freezer compartment. The disadvantage of this solution is, in particular that drawer freezer in the closed position, is cooled internal space (refrigerator), so inside the Cabinet exterior surface of the mailbox will be cooled to the temperature of the refrigerator. Therefore, when opening a drawer, these cooled outer surfaces will be open for exposure to ambient air containing moisture which will condense on the cooled surfaces that will lead to unwanted moisture accumulation. Condensation causes a transfer of latent heat from water vapor in a drawer, which leads to the need for additional cooling drawer after his return to the closed position within the Cabinet.

In addition, the condensed moisture will be transferred into the internal space of the refrigerator, when the drawer is closed. As mentioned here previously, the presence of water promotes microbial activity. Another disadvantage associated with what tupinier water in the inner space of the refrigerator, is that it can freeze; this creates special problems in the intersection of a closed box with an insulating cover, since the deposition of hoarfrost in place of the sealing can block a drawer and not to allow it to open. In fact, this ice formation due to moisture penetration through the pairing of a drawer and the top wall. This deficiency was known to the author of the said patent, as the patent GB 602329 mentioned Cam mechanism for destruction of ice in place of the seal or on the guide chutes or other supporting surfaces of the drawers. Note that the formation of ice in place of the sealing can also lead to deterioration of seals due to violations of the right pair included in the contact surfaces of the seal. Needless to say, the deposition (growth) of ice on the moving parts of the mechanism drawer is also undesirable because it can interfere with the movement of a drawer.

Another noteworthy document describing the prior art is U.S. patent No. 1337696. This patent focuses on the separation of refrigerated drawers, placed in the Cabinet, and the use of cooling devices installed directly above each drawer and close to him... is so to the specified mailbox could actually be considered as closed by adjunction to the specified refrigeration device. However, if the drawer should be opened between him and the cooling device must be left gap. As in the above patents great Britain, the presence of this gap will contribute to the deposition of ice, because the inside of the enclosure moist air penetrates into a drawer, and water vapor condense and freeze. The smaller this gap, the faster the deposition of ice will block the movement of a drawer. If you use a larger gap, it will lead to greater air leakage, and therefore, this fridge will have a lower energy efficiency and will be more susceptible to cross-contamination.

In addition to the foregoing, in U.S. patent No. 1337696 leak cold air reduces the temperature inside the Cabinet around the drawers and thereby increases the likelihood of condensation on the drawers when they are open. It should be noted that the cold air flowing so freely falling drawers inside the Cabinet, resulting in the outer surface of the drawers will be in contact with air at a temperature substantially below ambient temperature. Some of the women Italy design, described in U.S. patent No. 1337696, exacerbate this effect. For example, the lower wall of this known device is an effective insulator, which significantly reduces the temperature on the surface of drawers. In addition, the internal dividers between drawers makes it impossible to heat transfer from the ambient air to drawers, providing only the possibility of heat transfer between the drawers and, thus, contributing to the gradual equalization of temperature between the different drawers. Large areas of the outer surface of each drawer left inside the Cabinet for a long time or even overnight, cooled to a temperature which is considerably below the dew point of the surrounding air. So if you open these drawers on these surfaces immediately will be condensation or frost. Similarly, if the drawers removed and left outside the refrigerating chamber, they will begin to moisten with condensation.

As in the above patents great Britain, opening and closing drawers in the device according to U.S. patent No. 1337696 acts like a piston, alternately creating a vacuum and pressure in the neighboring areas. It promotes the transfer of air when opening the drawer front Cabinet, and et is t air can displace the cold air, located in the drawer, and the Cabinet. The increase in the size of the Cabinet compared to the dimensions of the drawers may reduce the piston effect, but there will be a cost effective solution in terms of the volume of the refrigeration Cabinet. And Vice versa - cooling Cabinet with the rational use of internal volume and dense layout can reduce the displacement of the cooled air and thereby reduce the cooling demand replacement of warm air, but will also increase the resistance to opening and closing of a drawer.

Along with the leakage of cold air gap, which in known constructions inevitably remains between the drawer and the lid large enough for the passage through it of enzymes, spores and other contaminants carried by air. Furthermore, in U.S. patent No. 1337696 revealed the presence of common drainage connecting drawers between them, and it also makes possible the transfer of pollutants between all drawers, especially due to the aforementioned piston effect.

Although U.S. patent No. 1337696 says different temperatures in different drawers, cooling caps are connected in series and have no funds for individual temperature control in each drawer is the taxpayer. The difference of temperatures constructively provided by the fact that some of the drawers are equipped with a large number of cooling elements than others. In addition, as with the sections of the more common refrigerators, each drawer for U.S. patent No. 1337696 has a specific function, namely the function of the freezer or refrigerator.

Even if you remove drawers for U.S. patent No. 1337696 from the cooling chamber they remain attached to their front panels and reference guides. It is not possible to use these drawers for temporary storage or transportation. Moreover, as in the patents great Britain, drawers for U.S. patent No. 1337696 cannot be opened fully; they appear only less than half, based on the load-bearing structure of the refrigerating chamber. This comes at the expense of ease of access to the contents of the drawers, as well as their visibility and lighting.

Finally, in a later document, reflecting the level of technology, DE 19546984 disclosed a refrigerating chamber, in which various tools are provided to prevent output of cold air when opening and/or removing the drawers. These products include seals that surrounds the drawers and used in combination with a hinged flap, which when removing the drawer p the network down closing the opening of a drawer or plate or similar element, which is located in the back of a drawer and moves with the drawer, blocking the hole when removing the drawer. However, none of these design solutions shall not reduce or prevent the flow of air and its mixing with the air inside the Cabinet of the refrigerating chamber due to the piston effect that occurs when opening and closing drawers. For example, all drawers have open top and mounted in a common refrigerated Cabinet. In addition, the resistance to opening and closing of the drawers increases to the extent that the air flow is restricted.

On the background of this prior art and was created by the present invention.

In one aspect of the invention is to create a cooling chamber containing at least one container, the load-bearing structure made it paroizoliruyuschimi separation of the container from which the container can be removed to open it with access to its interior space and in which the container can be returned to its closure and cold storage items in the container, and valve means in communication with the compartment of the container for air intake outside of the refrigerating chamber, while removing the containers the RA from his office, to output the air outside of the refrigerating chamber when returning the container into the office and to maintain the vapor barrier separation of the container when the container is in his office. This weakens the piston effect, which otherwise, for a device with multiple containers, would contribute to cross-contamination of containers.

The invention also consists in the creation of the refrigerating chamber containing at least one container, the load-bearing structure made it paroizoliruyuschimi separation of the container from which the container can be removed to open it with access to its interior space and in which the container can be returned to its closure and cold storage items in the container, and insulating means mounted sliding and folding along the branches of the container when removing the container from its branch and the return of the container into the office, maintaining a vapor barrier seal to (i) isolate the interior of the container from the air sucked in the office container when removing the container, and (ii) for displacement of air from the compartment of the container when returning the container to its office. It also weakens the piston effect and reduces the associated risk of cross C the pollution by maintaining the vapor barrier seal between the inner space of the container and the air in the compartment, the replaceable container. For example, the insulating means may be in the form of bellows mounted sliding along the surrounding walls of the compartments of the container. Insulating means in the extended position may occupy most of the volume of the compartment of the container or almost all of its volume

For a better understanding of the present invention, it is considered below as an example of its implementation with reference to the following drawings:

On Fig VI shows the side view in section of the two drawers of the refrigerating chamber, shown in Fig.9(a), 9(b) and 9(C), provided with a bellows to minimize the admission of air into the compartment drawers when opening and closing drawers.

Figure 1-4 shows the refrigeration/freezer 2, made in accordance with WO 01/20237. Refrigerating chamber 2 has a vertical cubic configuration (shape) and includes five rectangular opening on the front side of the drawer 4, arranged one above the other and installed in the Cabinet (enclosure) 6, which has the top 8, bottom 10, the side 12 and rear 14 panels. Any of these panels can be omitted (removed), if there is a desire to embed the refrigerating chamber 2 between the other support structures; in particular, the side panels 12 can be omitted, if the walls of adjacent cabinets can perform the function of the side panels 12. Panels 8, 10, 12, 14 may be or may not be structural members, and if they are not structural members, the frame (not shown) provides a support for various parts of the refrigerating chamber. If provided by frame, there is no need to have power (bearing) of the panel.

Drawers 4 can slide to vdvinut'sā horizontally in the Cabinet 6 and be nominated by the guides on the sides of the drawers 4, which will be described later in more detail. If the rear panel 14 on the no, then, theoretically, drawer 4 can be extracted from the Cabinet 6 in two directions, as shown in figure 2.

Each drawer 4 contains insulated open top bucket container 16, and at least one container 16 (in this case, the container Central drawer 4) has a different depth compared to other containers 16 that allows you to have a different internal volume. These containers 16 in the description of the present invention will be referred to as boxes for storage or just boxes 16. The lower frame 16 is only a narrow gap relative to the bottom panel 10 of the Cabinet 6, while the upper basket 16 leaves considerable space in the upper part of the refrigerating chamber 2 under the upper panel 8, which can be created branch 18 for the motor of the refrigerator 20, containing, for example, the condenser and the compressor, which in itself is well known.

Relatively deep box 16 Central drawer 4 is designed to store bottles and other relatively high products that should be stored vertically, while the other is relatively small ducts 16 are designed to store relatively low products. Compared with shelves and other compartments that are divided into the primary storage volume normal, upright refrigerator, the CE boxes 16 are favorable regarding the form, namely, the width of the main access holes compared to the depth of separation, in which access is provided. It is therefore very easy to reach any part of the internal space of the duct 16 when the drawer 4 is open (extended).

The inner space of the Cabinet 6 is divided by five isolated caps 22, one for each drawer 4, which are usually flat and arranged horizontally. When the drawer 4 is closed, then open the upper part of its respective duct 16 is closed by means of a corresponding one of the covers 22, as will be described later. Cover 22 contain cooling means 24, which represents evaporative elements of known type, mounted on the bottom surface 26 of each cover 22 and designed for cooling the contents of the boxes 16, closed this cover 22.

Each duct 16 has a mainly flat front side 28, which is open when the drawer 4 is closed (pushed). Front side 28 may be provided with a decorative panel, which is in itself known. When the drawer 4 is closed, the front side 28 of the duct 16 is bordered on the top panel control unit 30, the designated boxes 16, and the panel 30 is in the same plane with the front side 28. The panel 30 is supported by the front CROs the key 32 of the cover 22, moreover, the panel 30 is entered in the notch of the front edge 32 of the cover 22.

The panel control unit 30 has a number of indicators, switches and elements of the audible alarm, which form the user interface for each of the boxes 16. This interface, in most cases, can be used, for example, to select the temperature to which the cooling duct 16. This interface has a temperature indicators, switches on and off and quick freezing, and the indicator lamp open state of the drawer 4 and audible warning device is triggered by exceeding the specified time, the open state of the drawer 4 or upon reaching the upper or lower limits of the temperature inside the box 16.

Rounded handle 34, which is mainly the entire width of the upper section of the front side 28, allows you to nominate a drawer 4, when access is required in the internal space of the case 16.

The base of the front side 28 of each of the boxes 16 fringed slit 36, which, as will be described later, is used to access the ambient air in the Cabinet 6. To this end, each slot 36 communicates with an air gap 38, passing under the entire side of the base 40 of the respective boxes 16 and out into the empty space 42 provided behind each of the boxes 1, moreover, this space 42 is limited by the inner surfaces 14 and the rear side 12 of the panels of the Cabinet 6 and the rear part 44 boxes 16. As is partially shown in figure 4, the blank space 42 passes behind each duct 16 from the bottom 10 of the Cabinet 6 and communicates with the compartment 18 of the motor of the refrigerator at the top of the Cabinet 6.

Air gaps 38 in boxes 16 and empty space 42 behind the boxes 16 are communicated with an air gap 38 at the sides 48 boxes 16. Side panel 12 of the Cabinet 6, adjacent to the ducts 16 may be provided with ventilation channels 46 through which can also enter the surrounding air. As is best shown in figure 3 and 4, the air gaps 38 are all around the rods to the upper side of each box 16, so that the ambient air that enters the Cabinet 6 through slots 36 may freely circulate around the sides 48, a bottom 40 and the rear portion 44 of each of the boxes 16. It should also be borne in mind that ambient air can flow freely over the upper surface 50 of each of the cover 22. In order to allow the passage of this air flow over the top cover 22, over which there is no duct 16, is provided by the slit 36 under face 52 of the branch engine of the refrigerator 18.

It should be borne in mind that the piston effect when opening retractable asika, sucking ambient air into the inner space of the refrigerating chamber 2, does not create problems in accordance with the present invention. In fact, this piston effect is positive and promotes circulation of the ambient air inside the Cabinet 6.

Figure 4 shows that the engine room of the refrigerator 18 contains the impeller 54, which removes the air through the holes 56 provided on the front side 52 of the branch engine of the refrigerator 18. As is best shown in figure 1, these openings 56 are horizontally over the entire width of the front side 52. The impeller 54 is communicated with an empty space 42 behind boxes 16 and pulls the air from the empty space 42, thus facilitating the introduction of ambient air through slots 36 and, possibly, through the side vents 46. After entering the engine room of the fridge, this air passes through the heat exchanger grid 58 of the condenser.

Thus, the ambient air that enters the Cabinet 6 through the front slit 36 and, if they have, through the side vents 46, out of the Cabinet 6 through the holes 56 provided on the front side 52 of the branch engine refrigerator; therefore, ambient air is circulated through the Cabinet 6. More specifically, the ambient air at the entrance to the refrigerating chamber 2 cf the law of Ukraine comes into contact with the outer surfaces 40, 44, 48 boxes 16 and heats them up to ambient temperature (or close to it) before it is sucked into the empty space 42 and then goes up through the empty space 42 through air circulation. The arrows in figure 4 illustrates this circulation of air through the refrigerating chamber 2. Thus, the inner space of the Cabinet 6 is maintained at a temperature close to ambient, and only the inner space of each box 16 is cooled.

Due to the contact of the outer surfaces 28, 40, 44, 48 boxes 16 with warmer air than is contained in the box, no problem with condensation on the exterior surfaces 28, 40, 44, 48 and, hence, the problem of the transfer of the latent heat in the duct 16 or problems of deposition of frost or cross-contamination (contamination) of the condensed water in the Cabinet 6.

Anyway, the occurrence of cross-contamination is unlikely, as each box 16 tightly closed when pushed his drawer 4. Thus, even if the Cabinet 6 and penetrate the microbes, they can't easily do in other boxes 16. It is also unlikely simultaneous opening of the two boxes 16 at any point in time. Can be provided with means to prevent such a situation, for example using a mechanism similar to that used to protect the cabinets from the prokidyvaya, not allowing time to nominate more than one drawer 4.

When the box 16 is open, through its open top no significant leakage of cold air, and when the box 16 is closed, the horizontal seals 60, made in accordance with the present invention, provide the best seal for cold air than vertical seals, which are typically used in vertical refrigerators and freezers. Despite the fact that the use of horizontal seals are known for chest freezers, the present invention eliminates the inconvenience and problems of space inherent in the freezer with the lid on hinges, and is in these aspects similar to the much more popular vertical refrigerating chambers. The seals 60 may have magnetic properties, for example they can cuddle up to response surfaces using permanent magnets or electromagnets, or for their expansion or compression can be used in hydraulic or pneumatic means.

As between the cooled inner surfaces 62 of each of the boxes 16 and outer surfaces 28, 40, 44, 48 should be a significant temperature gradient, the ducts 16 are made of the most effective insulating material that allows you to maintain the exterior surfaces 28, 40,44, 48 ambient temperature or close to it the temperature. The ducts 16 mainly made of materials such as profenophos or polyurethane foam (with a possible coating fiberglass or polycarbonate composite structures).

If you want to split the contents of a particular box 16, the duct 16 may be provided with removable inserts 64. Inserts 64 are of various shapes and sizes and can be used to differentiate between branches of different types. For example, the insert 64 may be a thin wall, the length of which corresponds to the length or width of the duct 16, in which it is inserted. The insert 64 may be a box, with cover or without it, or may have latches to hold bottles, or tape to hold the eggs and the like, the Insert 64 may also be a basket or shelf.

As shown in figure 2, one or more ducts 16 may be removed from the cooling chamber 2 and is closed isolating the shipping caps 66. Box 16 in this case can be used separately from the refrigerating chamber 2, because of its isolation design ensures the preservation of content in the cold for a limited period of time.

For example, the receiver 16 can be used as a portable refrigerator with a possible saponangelo ice for increasing the time the content is saved in the cold. Alternatively, the duct 16 with shipping cover 66 may be located next to the refrigerating chamber 2 and to serve as a temporary capacity to store the content in the cold, while the refrigerating chamber 2 may be provided with an additional ducts 16.

You can also use conveyor cover 66 with an integrated cooling engine, powered from internal batteries or from a gas source, or from an external electrical network, or from the power of the car.

In the above-mentioned publication WO 01/20237 also disclosed means providing the ability to move boxes 16 with a significant horizontal component of movement for access into the internal space of the case 16, and a slight vertical component of movement performed by the box when it is opened for removal of the box from the lid 22, although such means are not shown on the General types 1-4.

Figure 5(a) and 5(b) shows the preferred nuances of executing caps 22 which close the ducts 16 after they are installed in the refrigerating chamber 2. Figure 5(a) shows that the cover 22 has an oblong shape in plan. In this drawing, the dashed lines also show the rectangular contours of the elements, are located under the cover 22. From the middle to the edges of these elements are the evaporator 194, u is contained in the center on the bottom surface of the cover 22, drain pan 196, located under the evaporator 194 for collecting water drops flowing from the evaporator 194, and a recess 198 in the lower surface of the cover 22 for placing a drain pan 196 and evaporator 194.

As shown in figure 5(b), which represents a section along the line a-a in figure 5(a) and capable of generating the visual representation of the given design, the notch 198 is limited skirt 200, the perimeter of the cover 22 and protruding from her bottom. On the lower end surface 202 of the skirt 200 is a pair of elongated compressible seals 60, one of which is inside the other. These seals 60 are continuous, not counting made them pass for the drainage channel 204 of the elongated cross-section, running in the backward direction from the drain pan 196. Drain pan 196 has a sloping base 206 for water flow to this drainage channel 204, remove water from the cover 22, as will be explained below with reference to Fig.6. To measure the temperature in the cavity, hermetically insulated duct 16 and the cover 22 may be provided a temperature sensor (not shown)passing through the skirt over 200 seals 60.

Figure 6 shows a preferred wiring diagram separate drain channels 208 of each drain pan 196 of the refrigerating chamber 2 with multiple drawers. This scheme code is t to minimize the risk of cross-contamination. Each channel 208 includes a U-shaped knee 210, forming a seal, and separately runs to the total tray 212. As shown in the drawing, the tray 212 may be located above the compressor 214 of the refrigerating chamber 2, to be allocated by the compressor 214 warmth gradually evaporated water in the tray 212 at least with the same speed at which the accumulation of water in the tray 212. In addition to this decision, or alternatively, he surface of the water in the tray 212 may abbatissa fan condenser of the refrigerating chamber 2 (not shown) to accelerate the evaporation of water.

Figure 7(a) and 7(b) shows another variant of the design cover, suitable for use in the cooling system dry type, in which air is supplied into the duct 16 and is discharged from it through an external refrigeration unit - node of the coil with a fan. Such a system also known as a system with forced air cooling, and figure 7(a) and 7(b), the cover 22 is made hollow and is divided into sections to control the flow of air, based on the principle of operation of such systems. Thus, the cold air cooled heat exchanger (not shown), is supplied under pressure by a fan (not shown) through pipelines in the distribution chamber supplied air 216 located in the cap is 22 on its periphery. From this cavity the air enters the duct through the distribution slit 218, arranged around a bottom panel 220, forming the lower surface of the cover 22. Warmer air out of the duct 16 through located in the center of the distribution chamber return air 222 chamber connected to the frame 16 through the Central opening 224 in the bottom panel 220 and the fan through the pipe 226 passing through the surrounding distribution chamber supplied air 216. This warmer air is sucked into the distribution chamber return air 222 under the influence produced by the fan discharge and then sent to a heat exchanger for cooling and re-enter through the distribution chamber supplied air 216.

In addition to the vertical layout of drawers 4 used in the above modifications of the design may location drawers 4 side by side, as shown in Fig(a), 8(b) and 8(C). Front view on Fig(a) represents the refrigerating chamber 268 horizontal configuration with four drawers, in which drawers 4 are arranged in the form of two adjacent racks, two boxes of 4 each. Thus, the refrigerating chamber 268 is sufficiently low for the organization over drawers 4 working surface, covering both the rack. T is thus, this variant of the invention suitable for use as a refrigeration unit with the function of the desktop for cooking and/or serving table.

The depth of the drawers 4 selected maximum with regard to height restrictions due to the installation of the engine 272 of the refrigerator and the control panel 274 side on one side of the refrigerating chamber 268, as shown in the drawing. In addition, the side view, shown in Fig(b), and enlarged detailed view Fig(C) in section along the line x-X on Fig(a) shows that the leading edge of the working surface 270 has a raised edge 276, which helps to prevent dripping of liquid spilled on the work surface 270 on the lower drawers 4 or leaking of the liquid inside the boxes.

On Fig(a) and 8(b) also shows how the proposed cooling chamber 268 may be mounted on wheels 278. These wheels 278 can be adjusted in height for installation of the refrigerating chamber 268 level on uneven floor 280.

Figure 9(a)shows the front view of the refrigerating chamber 332, which is functionally similar to well-known device of the above-mentioned U.S. patent No. 1337696 the fact that a significant portion of its outer surface in contact with the air temperature below the ambient temperature, but solves many of the inherent problems. On nachname mind refrigerating chamber, presented on Fig.9(a), similar to the refrigerating chamber horizontal configuration presented on Fig(a) and 8(b), and its drawers 4, the control panel engine 274 and 272 of the refrigerator are similar provisions under the work surface 270. Similarly, figure 9(b) - section along the line a-a in Fig.9(a) shows that each drawer 4 contains located in the Cabinet cover 22 and the duct 16, pull-out Cabinet forward on telescopic rails 74. Figure 9(C) - section along the line b-b In Fig.9(a) shows these guides 74, located on the sides of the box 16.

However, similar to the solution for U.S. patent No. 1337696 and in contrast to the above variants of the invention in this embodiment, the vertical moving boxes 16 relative to the cover 22 is not provided; instead, the duct 16 is simply slides horizontally next to the adjacent cover 22. Necessary in this regard, the gap between the duct 16 and the cover 22 requires a full outer vapor barrier of the entire Department, which houses a drawer, in order to solve the accompanying such constructive circuit problems moisture transfer and cross-contamination. Thus, as shown in Fig.9(b), the front panel 118 of each drawer extends out of the corresponding holes of the drawer is formed by a neighbour their lids 22 or cap 22 and bottom panel 334. A portion of each front panel 118, the overlapping edges of the respective holes, has on its back surface vertical magnetic seals 336, which when closed, the drawer 4 is tightly pressed due to its elasticity and magnetic attraction to the opposite front surfaces of the lids 22 and/or bottom panel 334 - depending on the location of the drawer. Department of drawers 4 also isolated from each other; this applies primarily to the holes and operational connections between adjacent branches. This also applies to drainage devices compartments drawers: drain line (not a drawing, not shown) must be displayed separately from each Department, and each such line must be included water trap, as in a drainage system, presented at the above 6.

Figure 9(C) also shows the angular bearing 338 boxes protruding from the guide 74 down for posting box 16 with the possibility of removing the latter. Each compartment drawer shall have a minimum volume that provides access to the duct 16 and the respective guide rails 74.

In the ideal case, the wall of each branch of the drawers should be made of thin material with low insulation qualities and all its outer surfaces which should be in contact with the ambient air. In practice, this ideal is unattainable, although you should strive to use a thin material, supplying heat to the Department of drawers from outside and promoting convective heat transfer within the compartment drawer. In fact, due to the insulating action of the outer shell compartment and having an air cavity around the duct 16 in combination with the cooling effect of the gap between the duct 16 and the cover 22 within sealed compartments gradually established a certain temperature gradient. In addition, in areas where the Department is bordered their outer surfaces with other departments, internal insulation cavity separation is rapidly increasing. This further cools the air around the duct 16 and thereby increases the temperature gradient.

For this reason, figure 10(a), 10(b) and 10(C) proposed three different approaches to minimize the impact of temperature gradients and cooling within each branch of the drawer of the refrigerating chamber, shown in Fig.9(a), 9(b) and 9(C). Figure 10(a) shows the circulation fan 340 is installed in the channel 342, the separation of the drawer 344. The fan sucks air from the Department 344 and pumps it back to the Department. Secured in this way the circulation of air in the compartment 344 maintains temperature uniformity of the exterior is of overhasty boxes 16. Figure 10(b) shows the electric heater or the heater on hot gas 346 mounted under the box 16 to create a convective flow of air within the compartment 344 and heating the greater part of the outer surfaces of the duct 16 to a temperature close to ambient temperature, equal to or even exceeding it. Figure 10(C) shows air gaps 348 similar to those described with reference to figures 1 to 4, except that these air gaps 348 are located around the branches 344 drawers and between them and not around the boxes 16. Although figure 10(C) is not shown, the air gaps 348 can pass through the sides of the compartment 344 drawer, and the bottom and rear of this branch 344, as shown in the drawing. And in this case, the air in the air gaps 348, if necessary, may be heated.

The next set of drawings, 11-13, shows the different types of air valves which reduce the piston effect appearing when opening and closing drawers 4 of the refrigerating chamber 332, shown in Fig.9(a), 9(b) and 9(c). Ha 11(a), 12(a) and 13(a) shows the state of the respective valves when the stationary box 16, for example when the box 16 is closed. Figure 11(b), 12(b) and 13(b) shows the state of the respective valves when opening boxes 16 and figure 11(C), 12(C) and 13(C) - a condition suitable for the proposed valve when closing the box 16.

Considering the characteristics common to all types of valves, presented on 11-13, those are the inlet port 350, the overlap of the intake valve element 352, the exhaust channel 354, blocked exhaust valve element 356, and an intermediate channel 358 connected to the branch 344 drawer and reported from the middle valve chamber 360, located between the above-mentioned valve elements 352, 356. The inlet valve element 352 in normal position resting on his saddle, 362, located around the hole 362 between the inlet channel 350 and the middle valve chamber 360, and opens in the middle valve chamber 360. Similarly, the exhaust valve element 356 in normal position resting on his saddle, 366, located around the holes 368 between the exhaust channel 354 and the middle valve chamber 360, but the exhaust valve element 356 is opened in the exhaust channel 354.

When the stationary box 16 both valve element 352, 356 are in their respective positions of rest, as shown in 11(a), 12(a) and 13(a). However, when opening the drawer 4 air is sucked from the middle valve chamber 360 in the direction of the branch 344 drawer, as shown in figure 11(b), 12(b) and 13(b). Under the action of the resulting low pressure in the Central valve chamber 360 intake clap the config element 352 is opened and lets the air from the inlet port 350 via the inlet hole 364 in the middle valve chamber 360, and from there to the Department 344 drawer. Conversely, when closing a drawer 4 the air is displaced from the Department of drawers in the middle valve chamber 360, as shown in figure 11(C), 12(C) and 13(C), which increases the pressure in the middle valve chamber 360 and opens the exhaust valve element 356. While the air trapped in the middle valve chamber 360, exits through the outlet 368 and leaves the outlet 354.

Through the inlet channel 350 absorbed the ambient air outside the Cabinet of the refrigerating chamber 332, and through the outlet channel 354, similarly, the air is discharged outside the Cabinet. Thus, the air is driven, for example, due to the piston effect when opening and closing the drawer 4 is not moved between departments 344 of the refrigerating chamber 332, which eliminates the possibility of cross-contamination of these branches 344. It should be noted that, while in the passive state or in the resting position, shown in 11(a), 12(a) and 13(a), the valves maintain the barrier Cabinet of the refrigerating chamber. The sizes and location of valves and the inlet and outlet channels 350, 354 must be such as to minimize the impact on the cooled air in the duct 16 when the box 16 is under the action of piston effect when opening and closing sootvetstvujushej the drawer 4.

Differences between valves, presented on 11-13, are mainly in the design of the valve elements and the seal relative to their nests. The valve elements 352, 356, shown at 11 and 12, represent the hard leaf or plate, having located on the periphery of the magnetic or compressible seal 370, interacting with seats 362, 366 valves to overlap the corresponding apertures 364, 368. In both cases, the valve elements overlap the corresponding holes 364, 368 under the action of gravity and differential pressure. On 11 plates 352, 356 valves hinged on the one hand, providing the possibility of lifting plates on the other hand, when they open their holes 364, 368. On Fig, however, plate 352, 356 valves resting on their nests 362, 366 loose and can be located with an inclination, as shown in the drawing, so that when they open their holes 364, 368 plate was raised mostly on one side. In contrast to the above, the valve elements 352, 356, shown in Fig represent curved aperture, the curvature and elasticity which shifts them to the closed position, but which elastic buckling under the action of pressure changes and open, straightening up against a bias force. On Fig also shows that the dia is regmi 352, 356 have elastic ring band 372, tight slots 362, 366 valves. The advantage presented on Fig diaphragm valve is that its action does not depend on gravity, so the valve can be installed in any desired orientation.

Another way to minimize cross-contamination offices 344 drawers is to maintain vapor barrier seal, acting on the entire length of stroke of the drawer 4. On Fig shows how to achieve such a vapor barrier seal and depicts two drawers 4 refrigerating chambers, one located above the other. The upper drawer 4 is closed, the bottom drawer 4 is open, and each of the boxes are provided with a bellows 374 attached to the rear surface of the box 16 of the corresponding drawer. The cross-section of each of the bellows 374 mainly corresponds to the shape and dimensions of the oblong cross section of the branch 344 drawer, and each bellows are able to move apart the full length of the compartment 344 drawer, walkable box 16. Thus, by analogy with the piston and the cylinder, the bellows 374 extendible, occupying almost the entire volume of the respective compartment 344 drawer.

Bellows 374 attached to the frame 16 of the upper drawer 4, impacto difficult for box 16 when the upper drawer 4 in the closed position, and the corresponding bellows 374 open the bottom drawer 4 fully extend. Obviously, each bellows 374 is closed at its end, to which it is attached to the frame, and is open at its rear end and the rear end hermetically attached at its periphery to the surrounding walls of the compartment 344 drawer with the formation of vapor barrier seal. The open end of each bellows 374 reported directly from the surrounding atmosphere to provide suction in the bellows 374 of fresh air when opening the drawer 4 and displaces air from the bellows when closing a drawer 4. However, there is no mixing of air entering the bellows 374, and air, are or were in office 344 drawer.

Similarly, by the contour of the heat locally to bring warmth to the skirt, protruding downward from the cover, to prevent settling of frost on the contact surface of the container and cover. Such heating can be electric elements or by means of hot gas and can be enabled permanently or only when necessary opening of the container. Among the many variations of the invention described in this description, means the contour of the heat can be applied to any modifications of the design, where otnositelnoi moving (preferably vertical) cover and box leads to the breaking of the seal and the outlet box from the lid (or Vice versa)so that the box can be fully opened for access.

There is also the possibility of recovery of heat from various heat-generating parts of refrigerating engines, such as heat exchangers or electric motors, etc. and supply this heat to heat the contact surface of the container and the cover or outer surfaces of the boxes in the office drawer. This saves energy by using waste heat, which would otherwise be discarded into the atmosphere.
