The present invention relates to a supercooling apparatus having a freezing chamber capable of storing an article in a supercooled state. More particularly, the present invention relates to an overcooling device that includes a pair of electrodes capable of adjusting the distance between the electrodes and applying electric field energy so that the package does not freeze.

Subcooling means that the liquid does not transition even below the phase transition temperature to a solid and maintains a high temperature phase, that is, a liquid state. In the natural state, for example, the supercooled water drop (supercooled water drop) is an example, even in the conventional refrigerator, the water or the drink does not freeze by chance in the case of the supercooled state. Meanwhile, as the principle of subcooling is applied to a refrigerator, there are a freezing method disclosed in Japanese Patent Laid-Open Publication No. S59-151834 and a freezing method disclosed in Japanese Patent Laid-Open Publication No. 2001-086967 and a refrigerator, which include an electric field in the object in the refrigerator. Alternatively, a technique of applying a magnetic field to maintain a subcooled state below a phase transition temperature is disclosed.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

Figure 2 is a schematic diagram schematically showing a non-freezing chamber including an adjustable electrode provided in the subcooling apparatus according to the present invention. Electrodes 230 for applying an electric field inside the non-freezing chamber 200 are provided at both sides, and the electrode 230 is connected to the power supply unit 232 to receive a high-current alternating current from the power supply unit 232. The distance between the pair of electrodes 230 may be adjusted according to the size of the storage container 210 accommodated in the freezing chamber 200. The distance adjusting member 234 is installed between the pair of electrodes 230 to adjust the distance between the electrodes 230. The distance adjusting member 234 may be an elastic member in a simple form, and may be an electric motor and a power transmission member. The storage container 210 accommodated in the freezing chamber 200 may be provided to the user so that a plurality of exchange containers 210 having different sizes may be exchanged. In this case, the user may select a storage container 210 of an appropriate size according to the size of the storage to be stored in the non-freezing chamber 200 and insert it into the non-freezing chamber 200. When the storage container 210 is introduced into the freezing chamber 200, the gap between the electrodes 230 is adjusted to match the size of the storage container 210. Therefore, the interval between the storage container 210 and the electrode 230 can be maintained within a predetermined interval. An elastic member may be provided between the electrodes 230 to allow the electrode 230 to maintain a predetermined distance from the storage container 210 by the restoring force of the elastic member, and the storage container 210 may be inserted into the freezing chamber 200. When the size of the storage container 210 is detected, the electric motor may be operated. When the interval between the electrode 230 and the storage container 210 is adjusted to be within a predetermined interval, the electrode 230 may defrost frost generated in the storage container 210 by heat generated to generate an electric field when power is applied. Can be. In addition, when the interval between the storage container 210 and the electrode 230 is narrow, the electric field can be more stably supplied into the storage container 210, and power efficiency can be improved.

When the same voltage is applied to the electrode 230, the narrower the interval between the electrodes 230, the stronger the electric field formed between the electrodes 230. Therefore, by adjusting the interval between the electrodes 230, it is possible to adjust the intensity of the electric field. On the contrary, in order to control the intensity of the electric field, the distance between the electrodes 230 may be adjusted.

3 and 4 are views illustrating a first embodiment of a supercooling apparatus having a freezing chamber including an electrode whose spacing is adjustable according to the present invention. The supercooling apparatus is provided with a freezing chamber 200 which can prevent freezing of moisture contained in the food while keeping the food below the phase transition temperature of the water. The freezing chamber 200 is defined by an outer case 220 which is a hexahedron with an open front surface.

Inside the outer case 220, an electrode panel 236 is attached to the electrode 230 and movable to adjust the gap. In addition, a cold air inlet hole 242 and a cold air outlet hole 244 are provided at the side or rear side of the outer case 220. Here, the cold air outlet hole 244 may be formed on the upper surface of the outer case 220 instead of the side or the rear side, such that cold air cooling the non-freezing chamber 200 may flow out into the refrigerating compartment.

Food is stored inside the outer case 220, that is, in the non-freezing chamber 200. When the package comes into direct contact with the electrode 230, a current is applied to the package, which may cause an electric shock. In addition, when the electrode 230 generates heat, if the supercooling of the food is terminated or the food is severe, the food may burn. Therefore, the enclosure must be stored in the freezing chamber 200 at a distance from the electrode 230. In order to prevent direct contact between the object and the electrode 230, a storage container 210 is inserted into the outer case 220 and accommodates the object. The storage container 210 is of a drawer type with an open top surface to facilitate a user to place an article in the storage container 210.

In addition, the storage container 210 is formed to be withdrawn from the outer case 220. In this case, the storage container 210 and the electrode panel 236 are provided with guide members 280 (282, 284) to guide the movement of the storage container 210. In the present embodiment, the electrode panel 236 includes the guide ribs 282, and the storage container 210 includes the guide grooves 284. However, the electrode panel 236 includes the guide ribs 282.

In addition, a handle 290 is formed in front of the storage container 210 so that a user can easily withdraw the storage container 210 from the outer case 220. The handle 290 is a groove or protrusion formed in front of the storage container 210. The handle 290 may be integrally formed when the storage container 210 is formed.

Since cold air flows into the outer case 220, frost may be generated on the inner surfaces of the electrode 230 and the outer case 220. When the frost is generated, the strength of the electric field applied by the electrode 230 is weakened, so that the energy efficiency is reduced. In addition, when the frost is generated on the inner surface of the outer case 220, not only the drawer of the storage container 210 becomes uncomfortable, but also when the frost falls into the inside of the storage container 210, that is, the freezing chamber 200, Can act as tuberculosis and cause food to freeze. Therefore, the frost needs to be removed. Accordingly, the supercooling device includes a defrosting device 250 that removes frost generated in the electrode. The defroster 250 may use a heater as a representative example. At the time of defrosting, power is cut off from the electrode 230 and the heater is heated to remove frost. When the heater generates heat, frost melts and defrost water is formed. If the defrost water is not discharged, it is preferable to discharge the defrost water immediately because the defrost water may freeze or generate frost again and is not sanitary. Therefore, the drain hole 260 is formed in the lower portion of the outer case 220. The drain hole 260 is connected to a drain flow path (not shown) to discharge the defrost water to the outside.

In addition, the sensor 270 that can detect the state of the freezing chamber 200 is installed. The sensor 270 senses the temperature of the freezing chamber 200 and the strength of the electric field applied to the freezing chamber 200. Continuously detects the temperature and the intensity of the electric field so that the condition of the freezing chamber 200 maintains the supercooling conditions, and transmits the temperature and the electric field to the control unit (not shown), the control unit (not shown), according to the flow rate of the cold air, the temperature of the cold air and The voltage applied to the electrode 230 is adjusted. The controller (not shown) determines whether the electrode 230 is defrosted, and operates the defroster 250. In addition, when the sensor 270 includes a function of detecting the size of the storage container 210 inserted into the outer case 220, the control unit moves the electrode panel 236 in accordance with the size of the storage container 210 to move the electrode. The interval between the 230 can be adjusted. In addition, the outer case 220 may be formed of a heat insulating material, or may include a heat insulating layer.

In the outer case 220, the electrode panel 236 is spaced according to the size of the storage container 210 inserted into the outer case 220. The storage container 210 may be provided to the user with a plurality of storage containers 210 having different sizes according to the type, size, and characteristics of the food. When the storage container 210 is inserted into the outer case 220 and the elastic member 234a installed in the outer case 220 pushes the electrode panel 236 by the restoring force of the elastic member 234a, the electrode panel 236 ) Is adjusted to maintain an interval within the predetermined interval with the storage vessel 210. A guide rib 236a for guiding movement of the electrode panel 236 is provided on at least one of an upper surface and a lower surface of the outer case 220, and the electrode panel 236 has a guide groove in which the guide rib 236a is accommodated. 236b. In addition, a gap maintaining protrusion may be formed in the electrode panel 236 or the storage container 210. In this case, the gap between the outer case 220 and the storage container 210 may be maintained constant by the protrusion. On the other hand, when the gap maintaining protrusions are not formed in the outer case 220 and the storage container 210, the outer case 220 and the storage container 210 are contacted by the restoring force of the elastic member 236. Through this configuration, the distance between the electrodes 230 can be adjusted according to the characteristics of the object to be stored in the non-freezing chamber 200, so that the intensity of the electric field can be adjusted according to the characteristics of the object. In addition, since the interval between the electrode 230 and the storage container 210 can be maintained within a predetermined interval, it has an effect of defrosting the frost generated in the storage container 210 by the heat of the electrode 230. In addition, by adjusting the voltage at the power supply unit 232 (shown in FIG. 2) to apply power to the electrode 230, the strength of the electric field formed between the electrodes 230 can be adjusted. In this case, while narrowing the interval between the electrodes 230, when the voltage is lowered to form an electric field, there is an advantage that the power efficiency is increased.

5 is a view showing a second embodiment of a supercooling apparatus having a non-freezing chamber including an electrode whose spacing is adjustable according to the present invention. The second embodiment has the same configuration as the first embodiment except having the electric motor 234b and the belt 234c instead of the elastic member 234a (shown in FIG. 3), and a change in the shape of some parts thereof. . The electric motor 234b transmits driving force to the electrode panel 236 through the belt 234c. In the second embodiment, the driving force of one electric motor 234b moves only one side of the outer case 220 by one belt 234c, but connects the plurality of belts 234c to one electric motor 234b. Thus, both sides of the outer case 220 may be moved. It is also possible to include a plurality of electric motors 234b and a plurality of belts 234c. In the case of adjusting the distance between both sides of the outer case 220 by the electric motor 234b, that is, the distance between the electrodes 230, the sensor 270 adds a function to detect the size of the storage container 210, thereby automatically. As a result, the gap between the electrodes 230 may be adjusted according to the size of the storage container 210. In addition, a distance between the electrodes 230 may be adjusted by inputting an electric motor 238 driving command by an operation unit (not shown). In addition, the sensor 270 detects the strength of the electric field formed between the electrodes 230, that is, the electric field applied to the non-freezing chamber 200, and when the intensity of the electric field is greater than the appropriate intensity, widens the interval between the electrodes 230. If smaller than the appropriate intensity, the interval between the electrodes 230 may be narrowed.

FIG. 6 is a flowchart illustrating a first embodiment of a method of controlling a supercooling apparatus having an adjustable electrode according to the present invention. The supercooling device is located in the outer case 220, the storage container 210, and the outer case 220, and includes a sensor 270, an electrode 230, and an electrode 230 that detect the size of the storage container 210. And a controller (not shown) for controlling the operation of the electrode panel 236, the electric motor 234b for moving the electrode panel 236, and the motor 234, the electrode 230, and the like, which are movable in the outer case 220. Include. The user may select one of the storage containers 210 having different sizes according to the characteristics and the size of the storage to be stored in the freezing chamber 200 to store the storage. The container 210 is then inserted into the outer case 220. At this time, the sensor 270 senses the size of the storage container 210 (S1), and transmits the information to the controller (not shown). The controller (not shown) adjusts an interval between the electrodes 230 to fit the size of the storage container 210 (S2). The electrode panel 236 to which the electrode 230 is attached is moved through the electric motor 234b to adjust the gap between the electrodes 230. When the same voltage is applied to the electrode 230, if the interval between the electrodes 230 is different, the strength of the electric field formed between the electrodes 230, that is, applied to the non-freezing chamber 200 is different. For example, the strength of the electric field required for each object is calculated in advance, and the interval between the electrodes 230 is calculated accordingly. The size of the storage container 210 is then determined to accommodate the containment. That is, according to the type of object, information about the storage container 210 in which the object is to be stored is provided to the user in advance, and the user selects and uses the storage container 210 accordingly. Since the spacing between the electrodes 230 is automatically adjusted according to the size of the storage container 210, the spacing of the electrodes 230 may be adjusted according to the type and size of the object. Through this configuration and method, there is an advantage that the intensity of the electric field applied to the non-freezing chamber 200 can be adjusted without changing the voltage of the power applied to the electrode 230.

7 is a flowchart illustrating a second embodiment of a method of controlling a supercooling device having an adjustable electrode according to the present invention. Detecting the size of the storage container 210 (S1) may include determining whether the storage container 210 is accommodated in the outer case 220 (P1) and detecting the size of the storage container 210 (P2). ). Thereafter, the step S2 of adjusting the interval of the electrode 230 according to the size of the storage container 210 is performed.

8 is a flowchart illustrating a third embodiment of a method of controlling a supercooling device having an adjustable electrode according to the present invention. When the user inserts the storage container 210 into the outer case 220, the sensor 270 senses the size of the storage container 210 through the sensor 270 (S1). Then, the interval of the electrode 230 is adjusted to the size of the storage container 210 (S2). In this manner, an interval between the storage container 210 and the electrode 230 may be adjusted within a predetermined interval. As described above, when the distance between the electrodes 230 changes, the intensity of the electric field formed between the electrodes 230 also changes. The sensor 270 senses the intensity of the electric field (S3), and adjusts the voltage applied to the electrode 230 when the intensity of the electric field is outside the range of the appropriate intensity (S4). For example, when the interval between the electrodes 230 becomes narrow and the intensity of the electric field becomes too strong, there is a fear that corona discharge occurs between the electrodes 230. In this case, the voltage applied to the electrode 230 may be lowered to prevent corona discharge. In addition, when the distance between the electrodes 230 is too far, the strength of the electric field is too weak, it may be difficult to maintain the supercooled state of the object. In this case, the voltage applied to the electrode 230 may be increased to maintain the supercooled state of the object. In this case, the power supply unit 232 for applying power to the electrode 230 should include a transformer capable of adjusting the voltage.

9 is a flowchart illustrating a fourth embodiment of a method of controlling a supercooling apparatus having an adjustable electrode according to the present invention. In the supercooling apparatus used in the present invention, the sensor 270 may detect the distance between the electrodes 230 instead of detecting the intensity of the electric field. Accordingly, the sensor 270 detects the distance between the electrodes 230 (S1), and adjusts the voltage applied to the electrode 230 to a preset voltage according to the detected distance between the electrodes 230. The controller (not shown) lowers the voltage applied to the electrode 230 when the distance between the electrodes 230 approaches, and increases the voltage applied to the electrode 230 when the distance between the electrodes 230 increases, The storage housed in the freezing chamber 200 may be stored in a supercooled state. The fourth embodiment is particularly useful when the distance between the electrodes 230 is manually determined according to the size of the storage container 210, not when the distance between the electrodes 230 is automatically adjusted by the controller.

10 is a flowchart illustrating a fifth embodiment of a method of controlling a supercooling apparatus having an adjustable electrode according to the present invention. In the fifth embodiment, the intensity of the electric field applied to the freezing chamber 200 is sensed (S1), and accordingly the distance of the electrode 230 is adjusted accordingly (S2). For example, when the intensity of the electric field is too large, corona discharge may occur, or the water molecules of the package may be vibrated excessively to cause the package to generate heat. In this case, the intensity of the electric field may be reduced by increasing the distance between the electrodes 230. In addition, when the electric field strength is too small, it is not possible to store the enclosure in a supercooled state, and the enclosure may be frozen. Therefore, when the detected intensity of the electric field is too small, the distance between the electrodes 230 may be narrowed to increase the strength of the electric field.

FIG. 11 is a flowchart illustrating a sixth embodiment of a method of controlling a supercooling apparatus having an adjustable electrode according to the present invention. In the sixth embodiment, the distance between the electrodes 230 is adjusted (S1), and the voltage applied to the electrode 230 is adjusted (S2) according to a preset value according to the distance between the electrodes 230. For example, the strength of the electric field according to the distance between the electrodes 230 and the magnitude of the voltage may be input to the controller in advance. Therefore, when the intensity of the target electric field is determined, the distance between the electrodes 230 may be adjusted, and then the voltage applied to the electrode 230 may be adjusted to adjust the intensity of the electric field. In addition, according to the distance between the electrodes 230, the strength of the voltage capable of forming the appropriate strength of the electric field can be input to the controller. Therefore, after adjusting the distance between the electrodes 230, the voltage can be adjusted to form an electric field of an appropriate intensity.

The supercooling apparatus provided by the present invention and the method for controlling the same may adjust the distance between the electrodes, and thus, adjust the distance between the electrodes according to the amount, type, and size of the objects stored in the non-freezing chamber, thereby applying an electric field to the non-freezing chamber. You can adjust the intensity.

In addition, the supercooling apparatus provided by the present invention and a method of controlling the same may adjust the magnitude of the voltage according to the distance between the electrodes, thereby preventing the electric field from excessively counting or decreasing and generating a corona discharge.

In addition, the supercooling apparatus provided by the present invention and a method for controlling the same may adjust the distance between the electrodes by sensing the intensity of the electric field applied between the electrodes.

In addition, according to the present invention, the subcooling apparatus and the method for controlling the same may adjust the distance between the electrodes according to the size of the storage container accommodated in the freezing chamber, thereby maintaining the distance between the electrode and the storage container at an appropriate distance.
