The technical field

This invention relates to refrigerating apparatus with camera for refrigerated products, as well as to the method of manufacturing a refrigeration apparatus.

The level of technology

In refrigerating apparatus, generally, the refrigerant circulates in a closed circuit. Thus, the refrigerant is first compressed by a compressor is condensed during the heat exchange in a first heat exchanger, expanded through a throttle, and then evaporated in the second heat exchanger at a low temperature during heat absorption.

As the second heat exchanger are used tubular evaporators, which can be accommodated in the chamber for chilled products. During operation of the tubular evaporator absorbs heat from the camera for chilled products, which leads to the cooling space inside the camera.

Often tubular evaporators are performed in the form of a coil held in the form of a meander through a certain area to ensure favorable conditions of heat exchange. However, these coils can easily be bent or displaced chilled products inside the chamber, whereupon they are subjected to significant mechanical loads, which in some cases can lead to their failure.

Disclosure of inventions

Thus, the objective of this invention is to provide such holodilnik.oplata, the evaporator tube which can be stabilized in a simple way.

Under refrigeration apparatus is understood to mean in particular a domestic refrigeration device, i.e., a refrigeration apparatus which is used for domestic purposes in the household, or possibly also in the field of gastronomy, in particular for the storage of food and/or beverages at a certain temperature in the volumes, ordinary household. Examples of such refrigeration apparatus can be refrigerated Cabinet, chest freezer, or a combination of refrigeration and freezer cabinets.

This task is solved with a refrigerating apparatus according to p. 1 of the claims. We are talking about the refrigeration apparatus with camera for chilled products, in which is placed a tubular evaporator with multiple tubular sections. In this case, at least one of the tubular sections passes through the wall of the chamber for chilled products, and tubular section passing through the wall of the chamber for cooled products, and at least one tubular section fixed relative to each other by means of the holding device.

This prevents the bending or displacement of the tubular sections under the action of chilled products and thus a high mechanical load on them. In addition, thanks to this performance in Sogno the use of the tubular evaporator, tubular section which at one stage of manufacture can be rotated relative to each other, and which are fixed relative to each other only after the completion of this stage. When this tube section can be detected, in particular, in one plane.

Fixed relative to each other of the tubular sections can, respectively, be direct and be placed in the chamber for chilled products, essentially parallel to each other.

The retaining device can be placed on the side of the tubular evaporator, facing the wall of the chamber for chilled products. Thus, it will be enough to secure the tube only on the opposite side by means of clamps or similar devices on the camera for chilled products.

The retaining device may be attached to the tubular evaporator by means of the fixing or clamping connection. This ensures simple installation of this device.

The retaining device can have at least two, and preferably at least three hooks, locking the tubular section. In addition, the holding device can have at least one support surface, upon which the tubular section. This ensures reliable the fixing tubular sections.

Tubular sections, for example, with the exception of tubular sections that are located towards the outer side of the tubular evaporator, can be connected to each other through the many located across the tubular sections (lateral) edges. Thus, the outer and middle tubular section can be rotated relative to each other, which provides certain advantages in the manufacture.

The retaining device may have at least one retention flange located between the two transverse edges and fixing one of the tubular sections. This provides improved fixation of the tubular sections and the holding device.

The retaining device may have a bottom wall which includes at least one hole for drainage of melt water. Thus, it is possible to provide a holding device that occupies a relatively large area, which will provide reliable fixation and along with this effective drainage of melt water.

The dimensions of the holding device can be set such that it is fixed relative to each other exactly 2 or exactly 3 of the tubular section. Because of this holding device can be so compact that it can be mounted one the hand.

Preferably two holding devices. In particular, one holding device can be provided on each side of the tubular evaporator, which is provided particularly reliable fixing of the tubular sections.

The retaining device can pass through the entire width of the tubular evaporator. Thanks to this performance, all of the tubular sections can be fixed with just one holding device. This holding device can be a bar in the form of, for example, angular or U-shaped profile. Limit may be lower (reference) segment planks, upon which the tube section and arranged opposite this segment of the strap retaining tabs, and the tubular sections are fixed between the lower segment of the strap and holding the tabs.

Between the holding fixture and the wall it is possible to install spacers. This spacer serves to hold the device has not moved back towards the wall and not damage located where the sensor or similar elements.

A method of manufacturing a refrigeration apparatus with camera for chilled products, in which is placed a tubular evaporator with multiple tubular sections, and at least one of the Aceh sections passes through the wall of the chamber for chilled products, includes the following step: fixing passing through the wall of the chamber for cooled products of the tubular section and at least one tubular section through the holding device.

When this tube section by fixing using the holding device can be mounted in the same plane.

In addition, the method comprises the following additional steps:

in particular, a flat location, at least part of the tubular sections of the interior walls for refrigerated products, not all of the tubular section of the tubular evaporator are in the same plane;

- filling the space around the camera for chilled products insulating foam;

- after filling the foam, the tubular sections in the same plane.

This enables the use of a tubular evaporator, which is of such flexibility that during the process of filling foam he can squeeze in a mass of foam or similar to the outer wall, and one piece tubular sections passes through the outer wall of the chamber for chilled products.

Thus, placed in the chamber for cooled products of the tube can be welded before filling with foam and along with this and which involved the possibility of moving the chamber walls for refrigerated products under the action of pressure of the foam.

The implementation of the invention

In Fig.1 shows the axonometric image is wrapped in a tubular evaporator 130 camera 110 for chilled products refrigerating apparatus 100. The camera 110 for chilled products has essentially the form of an open front side and a truncated rear sides of a rectangular parallelepiped with a top wall 120, a bottom wall 122 and 124, the left and right side walls 126 and 128 and a back wall with a ledge, which define the shape and dimensions of the internal cavity 160. The camera 110 for refrigerated products can be manufactured, for example, of plastic. Along the perimeter of the open front side of the camera 110 for chilled products installed frame 140. On each of the side walls provided by the presence, respectively, of the two latches 150, with which you can install partitions for vertical separation chamber for chilled products.

The camera 110 for chilled products wrapped the first of trubka the first evaporator 130, outside the chamber 110 for chilled products. During operation of the first tubular evaporator 130 is filled with a refrigerant, which evaporates while absorbing heat. The first tubular evaporator 130 absorbs the heat from the camera 110 for chilled products that provides cooling space inside the chamber 110 for chilled products.

Inside the chamber 110 for refrigerated products and presents the example in the upper area, i.e. close to the upper wall 120, is provided by the presence of the second tubular evaporator 200 in the form of a "stack", which is shown in Fig.2 in the form of axonometric image. The second tubular evaporator 200 is equipped with evaporative tube 210, as well as many transverse ribs 220. The generator tube 210 is, for example, from 10 straight tube sections 210A, every two of which at their ends are connected by a curved tubular sections 210b, allowing the generator tube 210 is in the form of a meander in the same plane. Transverse ribs 220 are, for example, straight pieces of wire and placed on both sides of the evaporator tube 210 is attached to it, for example, by soldering, etc., While the transverse ribs 220 are between the second and the penultimate straight tube sections 210A, so that the distance between the two ends of the tube 230 Monolake be changed by compression or stretching, and both ends of the tube 230 can easily take out a certain transverse ribs 220 plane. By means of transverse ribs 220 of the tubular sections are held relative to each other, allowing the generator tube 210 receives a certain rigidity. On the other hand, improved heat transfer properties of the evaporator tube 210.

Both the outer straight tube section 210A pass through the rear wall of the chamber 110 for chilled products. These two outer straight tube section 210A serve as inlet and outlet pipes of the tubular evaporator 200.

Due to the presence of the second tubular evaporator 200 inside the chamber 110 for chilled products provide a more uniform temperature distribution, which in turn leads to the decrease of the standard energy consumption of the refrigeration apparatus. The first tubular evaporator 130 and the second tubular evaporator 200 can sequentially be connected to another stream. Thus, both the tubular evaporator 130, 200 operate using only one cooling circuit, and there is no need to equip other compressors, valves or similar for additional evaporator. On the inlet side can be connected tubular evaporators 130, 200 is not represented on the image of the throttle valve, and on the sides of the exit - to the compressor, for example, are not represented in the image of the linear compressor.

In Fig.3 shows the axonometric image of the refrigeration device 100 in cross-section, and the section is held in a perpendicular direction relative to the first tubular evaporator 130. In this refrigerating apparatus 100 through the strap 300 and the locking connection, for example by means of clamps 170, in the front zone of the chamber 110 for chilled products on the top wall 120 is fixed to the second tubular evaporator 200.

As can be seen in Fig.3 and 4, the second evaporation tube 210 is inserted into the bar 300, which, in turn, installed in the correct terminals 170 in the upper zone. The advantage of this arrangement is that the second evaporation tube 210 is held at a preset distance from the top wall 120. This ensures better circulation of cold in refrigerating apparatus 100.

In addition, in Fig.4 shows that three of the straight tube sections 210A fixed relative to each other by means of the holding device 500. More specifically, the first, second and third (counting from left to right) straight tube section 210A of the tubular evaporator 200 fixed relative to each other by means of the holding device 500.

As mentioned above, straight tube section 210A, except the two outermost straight tube sections 210A, fixed relative to each other through transverse ribs 220 to give them rigidity. But as transverse ribs 220 are not up to the two outer straight tube sections 210A, both the outer tube section 210 can be rotated relative to the average straight tube sections 210A. More specifically, both the outer straight tube section 210A may, on the one hand, be discharged from a particular medium straight tube sections 210A plane, and on the other hand, the average straight tube section 210A through compression or stretching of the tubular evaporator 200 in the plane can be displaced towards the outer straight tube sections 210A or from them, or to move in the direction of the straight tubular sections. In assembled condition, there is, in particular, the danger that the average straight tube section 210A can be squeezed out in an upward direction under the influence of chilled products, which leads to an increased mechanical load of the tubular evaporator 200. In addition, in the rear region of the internal cavity can accommodate the temperature sensor 400 to register the temperature inside the cavity. At offset established in the area sensor 400 of tube sections 210A, 210b tubular evaporator 200 in the direction of the back there is a danger that the tubular evaporator 200 natolknet is to the sensor 400 and hurt him. By fixing with the help of holding device 500 of the tube section 210A may be fixed relative to each other, providing a rigid preset position of the tubular evaporator 200. Along with this, the tube 200 also serves to protect the sensor 400 from damage under the action of chilled products.

In Fig.5A-5e shows the different types of holding device 500. In Fig.5A shows the axonometric image holding device 500. In Fig.5b shows the retaining device 500, bottom view. In Fig.5C shows the retaining device 500, side view. In Fig.5d shows the retaining device 500, top view. In Fig.5e shows the retaining device 500, front view.

The retaining device 500 comprises a lower wall 510, three hooks a, 520b and C and the side wall 530.

The bottom wall 510 has an essentially rectangular design with rounded corners, and, as seen in Fig.5b-5d, has the notch on the left side. The side wall 530 passes from the edges of this notch on the perimeter of the bottom wall 510 so that through the lower wall 510 and the side wall 530 is formed Cup-shaped form. In addition, the side wall 530 serves as a support for the tubular evaporator 200.

On the lower wall 510 has three hook 520, each of the th of which has one leg segment 522 and one shoulder segment 524. The reference segment 522 is essentially perpendicular to the bottom wall 530, and the shoulder segment 524 is held essentially at right angles to the support segment 522. The shoulder segments 524 are arranged in the longitudinal direction of the holding device 500, and their free end is directed to the left as shown in Fig.5b-5d. The shoulder segments 524 are, thus, essentially parallel to the bottom wall 510. The width of the hooks 520b and s and, in particular, their shoulder segments 524 such that they can easily pass between the transverse ribs 220. The width of the hook a may be more.

As clearly seen in Fig.5d, each of the hooks 520 may consist of two parallel placed the plate elements 528, which are interconnected located between the ridges 529.

In the area above the notches are two jumpers 540, which pass from the bottom wall 510 in the same plane in the forward direction. Since these jumpers 540 is made much thinner than the bottom wall 510, they can with relatively little effort to turn from the plane of the bottom wall 510. On its front side, each of the jumpers 540 has one upward wall 542, which is located essentially flush with the side wall 530, but in the vertical direction is slightly higher. In addition, submissions to the nom sample from the wall 542 depart longitudinal ribs 544 in the longitudinal direction of the holding device 500.

Installed, as shown in Fig.5b-5d, the left hook a has a tail section 526, which is directed slightly downwards. Together with the ridges 540 this tail section 526 forms a clamp which can be clamped tubular section 210A. Thus, the retaining device may be detachable connection with a tubular evaporator 200 through the locking or clamping connection. When this tube section 210A fixed downward side wall 530, in the direction of the back support segment 522 of the hook a, upward shoulder segment 524 hook a and forward end section 526 and the wall 542 or, respectively, the longitudinal ribs 544.

On both sides of the middle hook 520b between the reference segment 522 middle hook 520b and side wall 530 are transverse ribs 550. In addition, the anchor segment 522 of the rear hook s are transverse ribs 560, occupying approximately half the distance between the hook C and side wall 530. As the upper side of the side wall 530, transverse ribs 550 and 560 also serve as supporting elements that support the tube 200, as it follows from the detailed description below. In addition, the transverse ribs 550 and 560 increase its rigidity holding device 500 and thereby increase its stability in the awn.

In addition, on the side wall 530 in the middle of the hook 520b on both sides are holding protrusions a. The retaining tabs a are located just above the side wall 530, as shown in Fig.5s. The retaining tabs a are located at some distance from the transverse edges 550, and the distance holding protrusions a in the longitudinal direction of the holding device 500 from the reference segment 522 of the hook 520b corresponds to the diameter of the evaporator tube 210. Thus, the generator tube 210 in a fixed state in the middle of the hook 520b is fixed with four sides: on the downward side wall 530, in the direction of the back support segment of the hook 520b, upward shoulder segment of the hook 520b and forward retaining ledges a.

On the rear end of the holding device 500 on the side wall 530 are also holding protrusions 570b. The width of the retaining protrusions a and 570b is such that the retaining projections can draw between two adjacent transverse ribs 220 of the tubular evaporator 200. Preferably, the width of the retaining protrusions a and 570b was slightly larger than the distance between two adjacent transverse ribs 220, so that the transverse ribs 220 when entering retaining tabs a or, respectively, 570b slightly elastic of rasd Galis, that will provide additional fixation of the holding device 500 on tube evaporator 200.

The bottom wall 510 under the hook 520 has drain holes 580, designed for drainage of melt water. In addition, the drain hole 580 provide the optimal configuration for the manufacture of holding device 500 according to the technology of injection molding. The retaining device 500 can be manufactured, for example, from plastic.

In Fig.6A and 6b show how the three outer straight tube section 210A are captured by using the holding device 500. For this purpose, the holding device 500 is first supplied hooks 520 up under the tube 200. Then holding device 500 is shifted up, and hooks 520b and s start in the field of second and third and, respectively, third and fourth straight tube section 210A through transverse ribs 220. As between the first and second tube sections 210A no transverse ribs is not installed, the hook a can freely move up. Along with this, each of the retaining tabs a and 570b is introduced between two adjacent transverse ribs 220, and these ribs if necessary, can easily be moved apart. As a next step, as shown by the arrow in Fig.6b, the retaining device 500 is shifted to the left, that is. towards the extreme outer straight tube section 210A. When this jumper 540 pressed slightly downwards, and the shoulder element 524 of the first hook a - slightly upward, and thus the extreme outer tube section 210A is clamped. Along with this shoulder segments 524 hooks a, 520b, s shifted respectively on the first, second and third straight tube sections 210A. This ensures reliable fixation of the three tubular sections 210A: upward hooks 520, down the side wall 530, performs the function of a support, and transverse ribs 550, 560, in the direction of the back support segments hooks 522 520, and forward - retaining ledges a and wall 542 and an end section 526 of the resulting clip. Due to this fixation of tube sections 210A to exclude their rotation relative to each other. In addition, this ensures that the rigidity of the tubular evaporator.

Be aware that the above method of fixation of tubular sections 210 preferably allows all necessary operations to perform with one hand.

The above method of fixation of tubular sections 210 may be the last step in the method of manufacturing a refrigeration apparatus, described hereinafter in the example of Fig.7-9.

At the first stage of the method of manufacturing Azimi 170 put on the outside of the chamber 110 for chilled products in the recess in the upper wall 120 of the chamber 110 for chilled products, and shoulders of the clamp 170 is inserted through the through hole in the upper wall 120 of the chamber 110 for chilled products, after which the clamps 170 can, for example, to fix the adhesive tape. The result is shown in Fig.7: clamps 170 freely protrude from the upper wall 120 into the internal cavity 160 of the camera 110 for chilled products.

In the next step, the second tubular evaporator 200 is inserted into the internal cavity 160 of the camera 110 for chilled products, the ends 230 of the tubes of the second tube of the evaporator 200 is inserted through the through hole in the rear wall of the chamber 110 for chilled products, and the second tubular evaporator 200 is clamped at its two sections 210b curved clamps 170 on the upper wall 120. The next step is obviuse camera 110 for chilled products first tubular evaporator 130. After this, the first tubular evaporator 130 and the second tubular evaporator 200 may be joined together by welding, etc. Must be considered that the first and second tubular evaporator 130 and 200 can be installed in reverse order.

Now the camera 110 for chilled products is slid into the outer housing (not represented here) with the outer wall of the device and is fixed on it. Further, in the inner cavity 160 of the camera 110 for chilled products is a frame made of aluminum alloy which deposits or similar material, used when filling foam. This frame serves to stabilize and shall be of such dimensions that the lower side of the second tubular evaporator 200 rests on the upper side of the frame. This reinforced to increase the rigidity of the transverse ribs 220 middle tube section 210A presses upwards, and the top edge of the frame is placed between the extreme outer straight tube sections 210A. In other words, in this position, the extreme outer straight tube section 210A are in a different plane in the contrast medium tube sections 210A, which, as shown in Fig.8, are located below the upper wall 120 in parallel. More specifically, the outer straight tube section 210A in this position are two holes in the back wall at an angle to the terminals 170, placed in the anterior region of the camera for chilled products. In addition, the framework under the filling foam can prop up the back wall 620 and the side walls of the chamber 110 for chilled products inside.

Thus, it becomes clear why the transverse ribs 220 does not pass through all of the straight tube section 210A. If this were so, then the average straight tube section 210A would not have been able to squeeze in a frame under the filling of foam to the top wall 120.

The next step is the filling of teploizoljatsionnye the m foam intermediate space between the camera 110 for chilled products and the outer wall of the device.

Because the second tubular evaporator 200 rests against the upper wall 120, on the one hand, it stabilizes the upper wall 120, and on the other, transfers occur during the filling foam pressure on the top wall 120 on the frame, enabling the prevention of deformation or the appearance of dents on the top wall 120. In the drawings for reasons of clarity, not shown in the outer wall of the device or insulation foam.

After filling foam of the second tubular evaporator 200 is released from the clamps 170 and slightly falls down with its front side, as shown in Fig.9. This straight tube section 210A again placed in the same plane. Then on the second tubular evaporator 200 is installed strap 300. In conclusion strap 300 is clamped or fixed clamps 170. The result is shown in Fig.3. Thus, the second tubular evaporator 200 is no longer rests against the upper wall 120, and is at some distance from it, allowing optimum circulation of cold inside the chamber 110 for chilled products.

In this position, the tube 200 is fixed in the forward direction by means of the strap 300 and the clamp 170 is fixed on the upper wall. In addition, the outer straight tube section 210A recorded iravani through their strip through the rear wall of the chamber for chilled products. However, the average straight tube section 210A dangling and can therefore be easily moved or rotated under the influence of chilled products. So on the last stage of the three outer straight tube section 210A are fixed relative to each other by means of the holding device 500 as described above. In ready to use condition, the camera 110 for refrigerated products can be surrounded on five sides of the outer wall of the apparatus, and the front can be closed by the door.

According to the above described method of the second tubular evaporator 200 during the process of filling foam closely adjacent to the top wall 120 and stabilizes it, making it possible to prevent deformations or dents on it due to the pressure of the foam. In addition, all procedures soldering can be carried out on the second tubular evaporator 200 before filling with foam. In particular, you can solder the end of the tube on the output side of the first tubular evaporator 130 by the end of the tube of the second tubular evaporator 200 on the side of its entrance, and after that may be done to check for leaks before filling foam. If, on the contrary, the second tubular evaporator 200 is installed only after filling the foam, then the required complement Inoi leak testing.

Mention was made earlier description, in which the outer tube section 210A on the left side inside the cavity 160 of the camera 110 for chilled products are held together by a holding device 500; however, it is also possible to fix the outer tube section 210A relative to each other on the left and on the right side using the same holding device. This provides improved fixation of tube sections 210A.

Alternatively, it is also possible to provide a holding device 1000, which will take place across the entire width of the tubular evaporator 200. Such retaining device 1000 is shown as an example in Fig.10. Presented on Fig.10 holding device 1000 has a single support bar 1010 with six fixed thereto hooks 1020. More specifically, the ends of the support bars 1010 is one hook 1020, and these hooks 1020 fix both extreme outer straight tube section. In addition, in the region of each of the third (counting from the outside) of straight tube sections 210A is provided with two hook 1020, which is installed at a certain distance from each other. Thus, with this holding device 1000 are fixed relative to each other, four different straight tube section 210A. is that the retaining device 1000 also recorded by it is placed beneath the tubular evaporator 200, then shifted up, and then by shifting to the left of the tube section 210A fixed hooks 1020.

Of course, described in the beginning of the performance form is preferable in that the holding device 500 can be installed with one hand and, in addition, requires less material consumption.

In Fig.11 shows another alternative form of execution of the holding device 1100. This holding device 1100 is available in the form of strips, consisting of the base section 1110 and the side section 1120, which are located at right angles relative to each other, forming an angular profile. This side plot 1120 is not along the entire length of the support section 1110 of the strap, and at least in its essential middle part. Alternatively, the retaining device 1100 may be U-shaped. At the end of the reference section 1110 of the strap is bent in the shape of the letter U, resulting in a U-shaped hook 1130. At the other end in the lateral section 1120 of the strap is provided a recess, which can be attached to the tubular section 210A. In addition, at this end is provided by the locking protrusions 1140. Also on the U-shaped hook 1130 is possible to provide the locking protrusions (not represented here). The retaining device 110 is fixed by the fixing tubular sections with these locking tabs.

In addition, from the lateral section 1120 of the strap in the forward direction depart the retaining tabs 1150 that capture the average straight tube section 210A and eliminate the possibility of bending upward.

In addition, on the outer straight tube sections 210A between the rear wall and the side section 1120 of the strips are rubber pads 1160. These pads 1160 function as spacers and ensure that the retaining device 1100 will not jump back to contact with the sensor 400.
