The present invention relates to a refrigerating compartment of the refrigerator containing it, and the way to manage them. More specifically, the present invention relates to a refrigerator containing the self-contained cooling compartment, which may be overcooled water drink and maintain a supercooled state of the beverage, as well as to the method of controlling a refrigerator, in order to minimize the fluctuation of temperature in the refrigerating compartment to maintain the supercooled state of the beverage.

Thanks to the advances in technology refrigeration equipment needs in cold and delicious, the drinks were initially satisfied with the drinks, with the consistency of cream, which can be produced by freezing of the drink in the refrigerator, and then, in recent times satisfied drink a thick type (hereinafter called "thick drink"), which has an intermediate phase between the beverage in the form of a liquid phase and ice cream in the form of a solid phase, and can be prepared by mixing the drink and particles of ice.

In the case of a typical refrigerator thick drink made by mixing a given drink and crushed ice.

However, such a thick drink does not fully satisfy the requirements of the user of the problem, consisting in the fact that a thick drink of newdon is to obtain due to the large size of the particles of ice and he seeks to change your taste due to the dilution of the beverage over time.

Thus, to meet the needs of the user, as described above, you must obtain a thick beverage that is unlikely to dilute and contain homogeneous and small ice particles, suitable for keeping in a thick drink.

From patent application U.S. 2003/0029178 A1, published 2003, a device hypothermia, containing a storage compartment, which is served chilled air from the feeder cooled air unit for cooling, located in the storage compartment, cooled chilled air for cooling the product in it and with a container to form a space in which to store the product, the hole to ensure the passage of flow of the chilled air in the compartment for hypothermia and from it and the valve for opening or closing the holes.

From the same application U.S. is known for a refrigerator, comprising a housing with freezer compartment formed therein, a storage compartment formed independently from the freezer compartment in the housing, the compartment for cooling, located in the storage compartment for indirect cooling of the product therein and containing container to form a space in which to store the product, the aperture providing a passage of chilled air in the compartment for hypothermia among him, and the flap.

In addition, from the same application U.S. is known for a refrigerator, comprising a housing with freezer compartment formed therein, a storage compartment formed independently from the freezer compartment in the housing, the feeder cooled air cooled air from the freezer compartment into the storage compartment, the compartment for cooling, located in the storage compartment cooled by cooled air supplied from the feeder cooled air for indirect cooling of the product therein and containing container to form a space in which to store the product, the aperture providing a passage of chilled air in the compartment for hypothermia and him, and the valve, a temperature sensor mounted within the compartment for cooling, for measuring the internal temperature of the compartment of hypothermia, and a control device for controlling the feeder cooled air on the basis of the temperature information generated by the temperature sensor.

From the same application U.S. known and the method of controlling a refrigerator, in which the measured temperature T in the Department for hypothermia, compare the temperature T, at least one of the first predetermined temperature set as a temperature of the beginning operado the spent cooling of the product after immediate cooling, and with the second set temperature is set as the target temperature, and control the device cooled air and a valve for adjusting the flow of the cooled air from the storage compartment to the Department for supercooling in accordance with the temperature T in the Department for hypothermia for selective implementation of the direct or indirect cooling of the product in the hospital for hypothermia.

In accordance with this known method and in such refrigerators, in particular a device for cooling a thick drink can be produced by supercooling the beverage prior to its freezing point or below, that he was not in a frozen state, followed by submission of nuclei of crystallization of ice or impact shock or vibration to the freezing of the beverage in the supercooled state.

Meanwhile, the production of such a thick drink must be overcooled water drink prior to its freezing point or below, that he was not in a frozen state, and to maintain the supercooled state of the beverage.

Typically, the water undergoes a phase transformation and passes from the liquid phase to the solid phase, i.e. ice, at a temperature of 0°or lower at 1 atmosphere. Under certain conditions the water is supercooled state without phase ol the rotation. When water is supercooled state, this state is relatively unstable, since water has a higher free energy than the water in the solid state. Here the term "free energy" means the amount of energy that can perform efficient work when given a chemical reaction continues. In accordance with the second law of thermodynamics any thermodynamically isolated system tends over time to move from a high energy state to lower energy state. Thus, from the point of view of the free energy of the chemical reaction proceeds in the direction of decreasing free energy.

In other words, a state in which water is supercooled state without freezing at the freezing point or lower at 1 atmosphere, in thermodynamics is called a metastable state. When the drink is in a metastable state, it is not in the equilibrium state, neither completely unstable state. Thus, if there is an external disturbance, drink instantly undergoes a phase transformation and goes from a supercooled state in the ice, which is more stable phase. That is supercooled beverage is frozen. The result is very difficult to maintain prod is in the supercooled state.

Theoretically, the minimum temperature at which pure water is supercooled state, not freezing, is about -40°C. in practice, However, water freezes at a much higher temperature as compared with theoretical temperature.

Therefore, when the temperature range, providing a supercooled state of water, without freezing, below freezing, defined as the degree of supercooling can be understood that the degree of supercooling of drinks, including water, in practice is very small in contrast to theoretical degree of hypothermia. In other words, can be understood on the basis of experience that temperature range, providing a supercooled state of the beverage, very narrow and that the drink instantly freezes at a temperature slightly below the freezing point.

In view of the above it is very difficult to produce a thick drink through a cold drink in the famous refrigerators. Specifically, each drink has its own degree of hypothermia, different from others, due to their different content, and, thus, difficult to maintain every drink in the supercooled state. In addition, even if you have provided the degree of supercooling the beverage, it is very difficult to maintain a supercooled state of a particular drink, and housego low degree of supercooling, as in the conventional refrigerator is temperature variation in a wide range as a result of uneven circulation of cooled air in it.

In addition, even if the beverage can be maintained in the supercooled state, because it requires a long period of time to be overcooled water drink for the production of thick drink, you will have a very long wait to get a thick drink.

Therefore, the object of the present invention is to provide a refrigerator which can support the Department store: for a drink at the optimum temperature for stable hypothermia drink and maintain the beverage in the supercooled state, and which can quickly produce supercooled beverage while maintaining the supercooled state of the beverage after a cold drink, and how to control them.

Options done by the means described below to explain the present invention with reference to the drawings.

In the production of supercooled beverage for thick drink must be overcooled water product, i.e. drink, but do not freeze at the freezing point or below, and to maintain the supercooled state of the product. To maintain the supercooled state of the product is important from the point of view of temperature to reduce the fluctuation range of temperature, and from the viewpoint of a violation, to reduce the influence of vibration or shock to the product.

The present invention relates to a device that supports the supercooled state of the product from the point of view of temperature and, particularly, to a device which can constantly maintain the supercooled state of the product from the point of view of temperature with very rapid hypothermia product.

Because each drink has its own degree of hypothermia, it is necessary by testing and probability analysis to determine the temperature at which the beverage begins to change from the supercooled state to a frozen state, i.e. the critical temperature of the cold.

In accordance with the test result from the use of such drinks like sodas, coffee, juice and the like, which are usually cooled down to drink, the critical temperature of the supercooling the beverage is in the range of about -8 ˜ -12° C. Thus, to maintain the supercooled state of the beverage, the temperature should be around -7°C. However, since each drink has its own degree of hypothermia, different from others, this temperature cannot be applied to all beverages, and, thus, the temperature range, providing specific drink his own degree of supercooling may be different from the others. Importantly, because the drinks usually have a small degree of exposure; in other words, because the drinks have a narrow temperature range, providing a supercooled state of the beverage, it is necessary to have a slight temperature variation during cooling.

The present invention is characterized by the fact that direct cooling is carried out within a specified period of time until, until it reaches the desired temperature by direct cooled air having a lower temperature than the target temperature, in order to quickly overcooled water product while maintaining the supercooled state of the product and then move on indirect cooling in order to prevent freezing of the product at a given temperature by maintaining the supercooled state of the product. Here temperature is round, installed as the temperature of the product when direct cooling of the product is replaced by indirect cooling, will be determined as the first predetermined temperature, and the temperature established as the target temperature to maintain the beverage in the supercooled state, will be determined as the second predetermined temperature. Preferably the first preset temperature is 0°and the second preset temperature is about -7°With, given the fact that the second preset temperature is the final temperature.

Details will be made reference to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Options for implementation are described below to explain the present invention with reference to the figures.

As shown in figure 1, the device hypothermia according to the present invention includes a housing 100, branch 220 for storage with insulation having a given size in the housing 100, and the Department of 200 to hypothermia in the Department 220 for storage with insulation. The device hypothermia further comprises a fan 231 as a single item feeder cooled air cooled air to the compartment 220 for storage. Here, the cooled air may be a standalone device.

Department 200 for hypothermia acts as a means of indirect cooling and is made from a material having a large heat capacity. Thus the separation of 200 to hypothermia is cooled independently when applying cooled air into it and indirectly cools the product M, located in it. Department 200 for hypothermia may include any design or device which provide indirect heat exchange through a specific environment, while preventing direct cooled air supplied to the compartment 220 for storage, the product M Since the separation of 200 to hypothermia has a very large heat capacity, it is unlikely to be refrigerated and absorbs heat from the product (or sends a chill in the product), thus cooling the product at a constant speed. That is, the separation of 200 to hypothermia provides indirect cooling of the product M by means of heat exchange between the product of M and a separation of 200 to hypothermia. You can regulate the amount of heat transferred between the product of M and a separation of 200 to hypothermia depending on the thickness or size of the compartment 200 for hypothermia.

In addition, the Department 200 for hypothermia is made with a hole 204 through which the cooled air passes freely into the compartment 200 to hypothermia or to direct cooled air to the product M Flap 250 is located at the unit 200 for hypothermia to control the quantity of cooled air entering the compartment 200 to hypothermia or leaving the C by opening or closing holes 204.

Department 200 for hypothermia performed with the sensor 260 temperature for temperature measurement branch 200 to hypothermia. Valve 250, the sensor 260 temperature and fan 231 is connected to the device 270 control, so that the device 270 controls the fan 231 and valve 250 on the basis of the temperature information generated by the sensor 260 temperature, to maintain a constant temperature in the compartment 200 for hypothermia. That is, the device 270 management serves to maintain a product M in the supercooled state by reducing the temperature fluctuations in the Department of 200 to hypothermia.

In addition, the Department 220 for storing formed with an air connection hole 223b, which connects the compartment 220 to store with the outer side to prevent stop receiving the stream of chilled air in the compartment 220 for storing, as a result of increasing pressure in the compartment 220 for storage, which may occur at a constant flow of chilled air in the compartment 220 for storage. Thus, it is possible to regulate the pressure in the compartment 220 for storage through the air connection hole 223b.

Embodiments of the fridge containing the device hypothermia, in accordance with the present invention will be described with reference n is 2 to 4.

The refrigerator in accordance with the present invention includes a housing 100, which consists of an inner cladding and an outer cladding, between which is filled with insulating material. The refrigerator provides a refrigeration cycle with a compressor, condenser, evaporator and fan, as well as other key elements. A detailed description of the common elements are omitted hereinafter for brevity.

Although figure 2 shows a refrigerator with sliding door 210 to open and close the unit 220 for storing a stand-alone device for hypothermia, the present invention is not limited to this design. Alternatively, the compartment 220 for storage may be provided with a hinged door, hinged on one side, top or bottom, opening offices 220 for storage. In constructions in which the Department 220 for storage there is a sliding door 210, so that the compartment 200 for hypothermia is installed in the compartment 220 for storage, as shown in figure 2, the door 210 has a support element 211 to maintain the separation of 200 to hypothermia on the side of the door 210 when opening or closing the slidable door 210 branch 220 for storage.

Department 200 for supercooling includes a container 201, which has in itself the specified receiving space and roofs is at 202 for opening and closing openings of the container 201. The cover 202 is fixed on the upper surface within the compartment 220 for storage by means of the mounting element 203 and contains a sealing element a for sealing space of the container 201 together with the container 201. Sealing element a engages with the inner surface of the valve housing 201 when sliding. The cover 202 is made at one end with a protrusion 202b for engagement with the recess 201b made at one end of the hole of the container 201. Compartment for cooling further comprises a ledge a formed on the side branch 200: for hypothermia to install slidable in the support element 211.

In the case of the construction described above, the cover 202 is fixed on the upper surface within the compartment 220 for storage, and container 201 is supported by the support element 211 fixed on the door 210, so that when the door 210 is opened, the container 201 extends outward from the Department 220 for storage, and when the door 210 is closed, the container 201 is pushed into the compartment 220 for storage. Thus, when the container 201 when the slide engages with the cover 202, it is installed in the compartment 220 for storage.

Meanwhile, the cover 202 is made with a hole 204 to ensure the passage of the cooled air supplied to the compartment 220 for storage in the compartment 200 claireosclaire or out of it, thus providing direct cooling of the product M, and with the flap 250 for regulating the flow of chilled air into it or out of it by opening or closing holes 204, thus enabling the management of the direct cooling of the product M Cover 202 is additionally equipped with a sensor 260 temperature to measure the temperature of the product M by measuring the ambient temperature.

Figure 3 depicts the refrigerator in accordance with the first embodiment, which contains a stand-alone evaporator 232 and offline fan 231 to control the device hypothermia regardless of the freezer compartment or a refrigerating compartment. Figure 4 depicts the construction in which the cooled air is supplied from the freezer compartment 120 to the Department 220 for storage through the channel 233 and fan 231. When this freezing compartment 120 has a device 121 cooled air, which contains the evaporator 122 to the freezer compartment. Specifically, figure 4 depicts the construction in which the channel 233, which serves for guiding the cooled air in the compartment 220 for storage, connects with freezer compartment 120, so that the cooled air is supplied from the freezer compartment 120 to the Department 220 for storage through the channel 233. Figure 4 represents the design is the construction, in which the office 220 for storage is in direct communication with the device 121 cooled air so that a portion of the cooled air generated by the evaporator 122 to the freezer compartment, directly to the Department 220 for storage.

First of all, the Department for hypothermia will be described with reference to figure 2, which contains a stand-alone evaporator and a fan for independent cooled air. With insulating material filled between the inner cladding and the outer cladding, the inner cladding forms a compartment 220 for storage. Department 220 for storing contains the door 210 to open or close the holes compartment 220 for storage, the support element 211 fixed on the door 210 and the squad 200 to hypothermia installed on the supporting element 211 and supported them.

Department 220 for storing separated by partitions 223 for education on the rear side of the compartment 224 of the cooled air. Compartment 224 cooled air is provided with a feeder cooled air is used to supply chilled air in the compartment 220 for storage and contains the evaporator 232 for the formation of the cooled air and the fan 231 for supplying cool air generated by the evaporator 232.

In addition, per the town 223 is formed with a connecting hole a about fan 231, so the cooled air from the compartment 224 cooled air is supplied by fan 231 Department 220 for storage through the communication hole a.

Meanwhile, Department 200 for supercooling includes a cover 202 is attached to the top surface within the compartment 220 for storage, and container 201, gear cover 202 from sliding. The cover 202 is formed with a hole 204 through which the cooled air supplied from the compartment cooled air passes into the compartment 200 to hypothermia or from it, and with the flap 250 for opening or closing the openings 204. The cover 202 has an additional sensor 260 temperature to measure the temperature of the product M Sensor 260 temperature can be set anywhere in the compartment 200 to hypothermia or on the inside of the compartment 220 for storage. In some cases, the sensor 260 temperature can be set very close to the product M for direct temperature measurement of product M. Therefore, even if the temperature sensor is not located near the product M, it is possible to measure the temperature of the product M by equalizing the temperature. In accordance with this embodiment, the sensor 260 temperature is made as an element that can measure the internal temperature of the compartment 200 for having areoplane.

Department 200 for hypothermia, is shown in figure 3, may further comprise a device temperature control for temperature regulation to ensure stable to maintain a constant temperature in the compartment 200 for hypothermia. Device temperature control regulates the temperature of the compartment 200 for hypothermia by regulating the supply of cooled air (which can be obtained by controlling the fan 231) or by regulating the flow of chilled air. Department 200 for hypothermia may further comprise a control unit refrigerant (not shown) to regulate the flow of refrigerant into the evaporator 232 using direct control of electronic expansion valve (not shown) or a control valve (not shown)that controls the refrigerant tube (not shown), through which the refrigerant emerging from the compressor (not shown).

Below will be described the operation of the refrigerator is shown in figure 3. First of all, when you want to overcooled water drink (i.e. the product M), placed in the compartment 200 for hypothermia, the valve 250 is provided in the compartment 200 for hypothermia, is opened via the control unit when the flow of chilled air in the compartment 220 when stored for the I through the connecting hole a by device cooled air, so some amount of cooled air is used for lowering the temperature of the compartment 200 for hypothermia, supporting branch 200 to hypothermia in cold conditions, and a certain amount of the cooled air is used to carry out the direct cooling of the product M after submission to the Department of 200 to hypothermia through the hole 204.

The temperature of the cooled air is equal to the critical temperature of hypothermia or below it. In other words, by direct contact of the cooled air having a critical temperature of hypothermia or below, product M product M can get cold quickly.

With the direct cooling of the product M sensor 260 temperature measures the temperature of the product M and sends it to the device 270 control, which closes the valve 250 when the temperature of the product M reaches a predetermined temperature. Then the product M indirectly cooled compartment 200 for hypothermia.

Since the separation of 200 to hypothermia is exposed to radiation heat transfer at constant temperature, the Department of 200 to hypothermia has little temperature variation, so that in the compartment 200 for hypothermia is supported by the constancy of temperature. Alternatively, the constancy of temperature in the compartment 200 for porekla the Denia can be reached through direct cooling of the product M in a given period of time without the use of a sensor 260 temperature, followed by closing of the valve device 250 270 control after a given period of time.

However, regardless of what the temperature in the compartment 200 for hypothermia constant, if the product M is in it for a long period of time, there is a constant supply of cooled air causes significant lowering of the temperature in the compartment 200 to hypothermia, so indirect cooling compartment 200 for hypothermia can be carried out at much lower temperature, causing a change in phase of the product m from the supercooled state to a frozen state. In this case, after the temperature in the compartment 200 for hypothermia, the sensor 260 temperature passes the information about the temperature in the device 270 control. Then the device 270 control determines whether the registered temperature compartment 200 for hypothermia near the critical temperature of hypothermia. If it is determined that the temperature of the compartment 200 for hypothermia is near the critical temperature of the supercooling device 270 control stops the flow of chilled air in the compartment 220 for storing and closes the valve 250, if it is open.

Termination of the cooled air can be achieved by stopping the operation of ventilat the RA 231 in the compartment 224 of the cooled air. More specifically, the opening and closing element (not shown) provided in the connecting hole a, through which the cooled air flows into the compartment 220 for storage of the compartment 224 cooled air through the fan 231, so that the opening and closing element closes the communication hole a simultaneously with the stop of the fan 231.

Meanwhile, the partition wall 223 is made with a hole 223b to the air stream, which connects the compartment 220 for storage compartment 224 cooled air, to adjust the pressure differential between them.

The second and third embodiments of the present invention will be described with reference to figure 4 and 5. The main elements of the second variant implementation, depicted in figure 4 are the same as in the first embodiment, shown in figure 3, with the exception of feeder cooled air. As shown in figure 4, the refrigerator of this variant implementation contains a Department of 200 to hypothermia, which uses chilled air supplied from the battery compartment 121 of the cooled air in the freezer compartment instead of a stand-alone device cooled air. Specifically, the refrigerator compartment contains 121 cooled air in the freezer compartment, which has an evaporator 122 d is I the freezer compartment for the formation of cooled air, which will be supplied to the freezing compartment 120, and the channel 233 which connects the compartment 121 of the cooled air in the freezer compartment with the compartment 224 of the cooled air of the refrigerator, so that the cooled air is supplied from the battery compartment 121 of the cooled air in the freezer compartment into the compartment 200 for hypothermia through the channel 233 through the fan 231. As shown in figure 5, the refrigerator of this variant implementation contains a Department of 200 to hypothermia, which uses chilled air supplied from the freezer compartment 120, and the channel 233 which connects the freezer compartment 120 with the compartment 224 of the cooled air.
