Description

Supercooling device {SUPERCOOLING APPARATUS}

The present invention relates to a supercooling device, and more particularly, to a supercooling device capable of directly supercooling a beverage (such as shochu) contained in a liquor container.

In general, a cooling device has a refrigerating chamber and a freezing chamber and has a simple function of storing food at a low temperature.

Supercooling used in a supercooling device refers to a phenomenon in which a melt or solid does not change even when cooled to below the phase transition temperature in the equilibrium state. Each material has a stable state according to the temperature at that time, and if the temperature is gradually changed, the members of the material can follow the temperature change while maintaining the stable state at each temperature.

However, when the temperature suddenly changes, since the members do not have room to change to the stable state according to each temperature, the stable state at the starting point temperature is maintained as it is, or a phenomenon occurs that a part changes to the state at the end point temperature and then dies. In the supercooled state, since the member is in an unstable state, if a shock is given, it freezes in the form of a slush. If this supercooled state is used, a drink in the form of a slush can be provided to the consumer.

A conventional supercooling device includes a main body in which a cooling chamber is formed to store a beverage container, a door that opens and closes one side of the body, a shelf installed in the cooling chamber to seat the beverage container, and cooling that cools the cooling chamber to a set temperature It is composed of parts and the like, and beverages (such as soju) accommodated in the beverage container are stored in a supercooling state by the internal temperature of the cooling chamber.

However, since the conventional supercooling device has a structure in which cold air in the cooling chamber is lost when the door is opened, there is a concern that the supercooling state of the beverage may be changed due to a change in the temperature of the cooling chamber. may not reach the supercooled state or freeze.

In addition, the conventional supercooling device is inefficient because a lot of time and power is used to raise the cooling chamber to the supercooling temperature, and there is a fear that the supercooling state of the beverage may be changed by the shock transmitted when the door is opened and closed.

Therefore, there is a need for a technology capable of minimizing the supercooling time of the beverage, maintaining a constant supercooling temperature while minimizing the power consumption, and alleviating the impact generated when the door is opened and closed.

And, it can be formed with a diameter that can be inserted into the lower end of the liquor container (10).

At this time, since the bottom surface of the cooling groove 230 is formed to be relatively thinner than that of the seating part 200 , it is possible to rapidly cool the bottom surface of the cooling groove 230 to be described later, and the side surface of the cooling groove 230 and Since the bottom surface surrounds the outside of the alcoholic beverage container 10 , cold air can be concentrated on the outer surface of the alcoholic beverage container 10 , so that the alcoholic beverage container 10 can be rapidly cooled.

The refrigerant circulation unit 300 has a length so that the refrigerant (R12, R22, etc., G) can move along the internal flow path 301, and is made of a metal (copper, etc.) material so that heat can be discharged to the outside. can Here, an outlet is formed on one side in the longitudinal direction of the refrigerant circulation unit 300 so that the refrigerant G can move to a cooling unit 400 to be described later, and the cooling unit 400 is located on the other side in the longitudinal direction of the refrigerant circulation unit 300 . An inlet is formed so that the refrigerant (G) that has passed through can be moved.

The cooling section 310 is a part for generating cool air by evaporating the refrigerant G that has passed through the expansion valve 430 to be described later, and at least one is formed along the longitudinal direction of the refrigerant circulation unit 300, and the cooling section The upper end of the 310 may be coupled in contact with the lower portion of the seating part 200 , and may be fixedly coupled to the lower surface of the seating part 200 by a separate fixing structure (not shown).

Here, the cooling section 310 is bent in a plurality of longitudinal directions as in FIGS. 4 and 5 to move the refrigerant G in the zigzag direction, but the bent shape of the cooling section 310 can be applied in various ways as needed. It is possible. In this case, the length of the cooling section 310 can be increased, so that the contact area between the cooling section 310 and the seating section 200 can be increased, and the entire area of the seating section 200 can be uniformly cooled and seated. It is possible to reduce the temperature deviation of the part 200 .

For example, the refrigerant G delivered to the inlet of the refrigerant circulation unit 300 evaporates to a gaseous state in the process of passing through the cooling section 310 to generate cold air, and the cool air generated in the cooling section 310 is The process in which the refrigerant G, which is directly transferred to the seating unit 200 and has lost cool air while passing through the cooling section 310, is moved to the cooling unit 400, which will be described later, is repeated.

The cooling unit 400 cools the refrigerant G moving along the flow path 301 of the refrigerant circulation unit G, and is disposed in the installation space 130 of the main body 100 , and the refrigerant circulation unit 300 ) while sequentially compressing, condensing, and expanding the refrigerant (G) delivered from the outlet, the process of moving to the inlet of the refrigerant circulation unit 300 is repeated.

Here, the cooling unit 400 includes a compressor 410 that compresses the gaseous refrigerant (G) delivered from the outlet of the refrigerant circulation unit 300 into a high-temperature, high-pressure gas, and a high temperature transferred from the compressor 410, A condenser 420 that cools the high-pressure refrigerant to change it into a liquid refrigerant (G), and a low-temperature, low-pressure refrigerant (G) while passing the low-temperature and high-pressure refrigerant (G) delivered from the condenser 420 through a capillary tube After changing to , it may include an expansion valve 430 that delivers it to the inlet of the refrigerant circulation unit 300 .

In this case, the refrigerant G delivered to the inlet of the refrigerant circulation unit 300 absorbs external heat while evaporating to a gaseous state in the process of passing through the cooling section 310 , and the gas passing through the cooling section 310 . The refrigerant G in the state is moved to the compressor 410 through the outlet of the refrigerant circulation unit 300 .

In addition, the compressor 410 may be provided with a compressor to which the refrigerant (G) is delivered, and a motor for compressing the refrigerant (G) delivered to the inside of the compressor, and the condenser 420 is removed from the compressor. It may include a condensing pipe for moving the transferred refrigerant to the expansion valve 430 , and a blowing fan disposed on one side of the condensing pipe and rotating a rotary blade to blow air to the outside of the condensing pipe.

That is, the refrigerant (G) can be continuously compressed while the motor is driven by the electric power transmitted from the outside, and the refrigerant (G) passing through the condenser 420 while the rotary blades of the blower fan are rotated by the electric power transmitted from the outside. ) can be continuously cooled, and an exhaust port 140 for discharging heat generated in the condenser 420 to the outside may be formed on the rear surface of the body 100 .

The temperature sensing unit 500 senses the temperature of the seating unit 200 in the inside of the cooling chamber 110 in real time and transmits it to the control unit 600 to be described later, which detects temperature changes and converts them into measurable signals. A temperature sensor may be used, and may be installed in contact with the seating unit 200 .

For example, when the seating units 200 are arranged to be spaced apart from each other in the vertical direction of the cooling chamber 110 , the temperature sensing units 500 are respectively coupled to the seating units 200 to be positioned at different positions. A temperature may be sensed, and a mounting groove may be formed in the seating unit 200 so that the temperature sensing unit 500 may be coupled in an inserted state.

Alternatively, the temperature sensing unit 500 may sense the temperature at a position spaced apart from the seating unit 200 . In this case, the temperature sensing unit 500 may be fixedly positioned in the cooling chamber 110 by a separate fixed structure (not shown), and the position and number of the temperature sensing units 500 may be variously applied as needed. This is possible.

The control unit 600 is for controlling the operation of the compressor 410 of the cooling unit 400 and the blower fan of the condenser 420 and the auxiliary cooling unit 700 to be described later, the installation space 130 of the main body 100 . It may be installed in the , and may be electrically connected to an external power supply (not shown) by a power cable.

Such a control unit 600 controls the driving of the cooling unit 400 to lower the seating unit 200 to a preset reference temperature within a predetermined time, and through temperature control of the seating unit 200 , the liquor container 10 . It is possible to supercool the beverage (such as soju) accommodated in the inside of the refrigerator.

In addition, the operation unit 610 may be provided with a display unit for externally displaying various information such as ON/OFF state and temperature, and the display unit uses a liquid crystal display (LCD). Also, a touch panel may be applied to the display unit to sense a user's touch.

The control unit 600 may drive the cooling unit 400 when the measured temperature transmitted from the temperature sensing unit 500 is higher than a preset reference temperature. At this time, since the temperature of the seating part 200 is lowered by the driving of the cooling part 400 , it is possible to prevent the temperature of the seating part 200 from being excessively increased, and the measured temperature transmitted from the temperature sensing part 500 . Accordingly, the operating time and intensity of the cooling unit 400 may be variably adjusted.

On the other hand, when the measured temperature transmitted from the temperature sensing unit 500 is lower than the reference temperature, the operation of the cooling unit 400 may be stopped. At this time, since the temperature of the seating part 200 rises by stopping the driving of the cooling part 400 , it is possible to prevent the temperature of the seating part 200 from dropping excessively. That is, the temperature of the seating unit 200 can be maintained at the reference temperature using the measured temperature transmitted from the temperature sensing unit 500, so that the beverage (such as soju) contained in the alcoholic beverage container 10 is not frozen in a supercooling state. can keep

The supercooling device according to an embodiment of the present invention includes an installation hole 150 that horizontally communicates the inside and the outside of the cooling chamber 110 as shown in FIGS. 8 and 9 , and a control unit 600 coupled to the installation hole 150 . ) and an auxiliary cooling unit 700 that discharges cold air to the cooling chamber 110 and heat to the outside of the cooling chamber 110 at the same time by the Peltier effect when current is applied. may include

Here, the auxiliary cooling unit 700 may use a thermoelectric element using the Peltier effect. The Peltier effect refers to a phenomenon in which one side of the thermoelectric semiconductor generates heat and the other side absorbs heat when a current flows in a circuit composed of a thermoelectric semiconductor.

The thermoelectric element is coupled to a circuit part 710 to which a plurality of P-type semiconductors and a plurality of N-type semiconductors are electrically connected, and one side of the circuit part 710, and an electrode is formed on one surface so that the P-type semiconductor and the N-type semiconductor are electrically connected. The cooling plate 720 is formed, and the heating plate 730 is coupled to one side of the circuit unit 710 corresponding to the cooling plate 720, and an electrode is formed on one surface so that the P-type semiconductor and the N-type semiconductor are electrically connected. may include

In addition, one surface of the heating plate 730 is provided with a metal material to dissipate heat, and a heat dissipation member 740 having a plurality of heat dissipation fins protruding from one side thereof is coupled to one surface of the heat dissipation member 740 , and rotates the rotary blade.

The cooling plate 720 is positioned in the direction of the cooling chamber 110 with respect to the circuit unit 710 , and the heating plate 730 is positioned in the opposite direction to the cooling plate 720 , and the cooling plate 720 from which cool air is emitted. may be exposed to the inside of the cooling chamber 110 . That is, since the cold air emitted by the heat absorption of the cooling plate 720 moves into the cooling chamber 110 , the temperature of the cooling chamber 110 can be constantly maintained by using the auxiliary cooling unit 700 .

Although not shown, one surface of the auxiliary cooling unit 700 from which cold air is emitted may be in contact with the edge of the seating unit 200 at the same height. In this case, cold air emitted to one side of the auxiliary cooling unit 700 may be transferred to the edge of the seating unit 200 , and the seating unit 200 may be cooled by the cold air emitted to one side of the auxiliary cooling unit 700 . can

For example, when a direct current flows through the electrode of the auxiliary cooling unit 700 , the cooling plate 720 emits cold air by absorbing heat, and the opposite heating plate 730 emits heat by heat generation. At this time, heat emitted through the heating plate 730 is discharged to the outside through the heat dissipation member 740 , and heat is rapidly discharged by the blower fan 750 , so that heat dissipation efficiency can be improved.

In the control unit 600 according to an embodiment of the present invention, a temperature exceeding range higher than the reference temperature may be preset, and the temperature exceeding the temperature range may be preset by 1 to 3 degrees higher than the reference temperature, and the cooling chamber ( If the temperature of 110) corresponds to the temperature exceeding range, the temperature in the range of 1 to 3 degrees can be adjusted by using the auxiliary cooling unit 700 .

For example, when the measured temperature transmitted from the temperature sensing unit 500 is within the temperature excess range, the auxiliary cooling unit 700 may be driven and the cooling unit 400 may be stopped at the same time. That is, when the measured temperature transmitted from the temperature sensing unit 500 is higher than the reference temperature, but does not deviate from the temperature exceeding range, the temperature of the cooling chamber 110 is lowered by 1 to 3 degrees by using the cold air emitted from the auxiliary cooling unit 700 . can do it

On the other hand, when the measured temperature transmitted from the temperature sensing unit 500 is higher than the temperature exceeding range, the auxiliary cooling unit 700 may be stopped and the cooling unit 400 may be driven at the same time. That is, when the measured temperature transmitted from the temperature sensing unit 500 is higher than the temperature exceeding range, the temperature of the seating unit 200 can be lowered by using the cold air emitted from the cooling section 310 of the refrigerant circulation unit 300, and , since the auxiliary cooling unit 700 uses the Peltier effect, the temperature of the cooling chamber can be finely adjusted, and the temperature can be adjusted with low power, thereby improving control performance and efficiency.

The supercooling device according to an embodiment of the present invention has at least one pressure adjusting unit 800 for reducing the pressure difference between the pressure in the cooling chamber 110 and the outside when the door 120 is opened or closed as shown in FIGS. 10 and 11 . may further include.

The pressure adjusting unit 800 includes a guide hole 810 for horizontally communicating the cooling chamber 110 and the outside, and a direction opposite to the cooling chamber 110 and the cooling chamber 110 inside the guide hole 810 . is disposed in the direction of the cooling chamber 110 with respect to the moving member 820 that can slide and the moving member 820, and elastically the moving member 820 in the opposite direction to the cooling chamber 110 by using a compressive elastic force.

Since the side orthogonal to the movement direction can be moved in both directions in a state in close contact with the inner circumferential surface of the guide hole 810 , the side surface of the moving member 820 is moved in a state in close contact with the inner circumferential surface of the guide hole 810 . The air in the cooling chamber 110 is not discharged to the outside of the installation space 130 or the body 100 through the guide hole 810 .

Here, the moving member 820 may be provided with an elastic material such as plastic, rubber, or silicone so that air does not pass through a portion in contact with the inner circumferential surface of the guide hole 810 , and the moving member 820 has a side surface and a guide hole. The inner circumferential surface of 810 may be in close contact with each other while forming a circumference.

The first elastic member 830 is for elastically supporting the moving member 820 in a direction opposite to the second elastic member 840, and one side elastically supports one end of the moving member 820 in the moving direction, and the opposite side. The other side may have a coil spring shape supported on one side of the guide hole 810 opposite to the moving member 820 . That is, since the first elastic member 830 elastically supports the moving member 820 in the cooling chamber 110 direction, when the cooling chamber 110 and the external pressure are balanced, the moving member 820 returns to the operation standby position. It can be placed in a state of

The second elastic member 840 is for elastically supporting the moving member 820 in a direction corresponding to the first elastic member 830, and one side elastically supports one end of the moving member 820 in the moving direction, and the opposite side. The other side may have a coil spring shape supported on one side of the guide hole 810 opposite to the moving member 820 . That is, since the second elastic member 840 elastically supports the moving member 820 in the direction opposite to the cooling chamber 110 , when the cooling chamber 110 and the external pressure are balanced, the moving member 820 waits for operation It can be positioned in a state returned to the position.

For example, when the door 120 is rotated in an opening direction, as shown in FIG. 10 , a pressure pulling in the opening direction of the door 120 is applied, so that a pressure difference between the cooling chamber 110 and the external space occurs. At this time, after the moving member 820 slides in the direction of the cooling chamber 110 while compressing the first elastic member 830 by the pressure acting on the guide hole 810 , the return elastic force of the first elastic member 830 . is returned to the original position by , and the pressure in the cooling chamber 110 is momentarily reduced by the movement of the moving member 820 , so that the pressure difference between the cooling chamber 110 and the external space can be reduced.

It is possible to open the door 120 without the need to open the door 120, it is possible to alleviate the impact generated when the door 120 is spaced apart from the front end of the body (100).

On the other hand, when the door 120 is rotated in the closing direction, as shown in FIG. 11 , a pressure pushing the door 120 in the closing direction is applied, so that a pressure difference between the cooling chamber 110 and the external space occurs. At this time, the moving member 820 compresses the second elastic member 840 by the pressure acting on the guide hole 810 and slides in the opposite direction to the cooling chamber 110, and then the second elastic member 840. The pressure difference between the cooling chamber 110 and the external space can be reduced because the pressure in the cooling chamber 110 is instantaneously reduced by the movement of the moving member 820 .

That is, the moving member 820 is moved in the opposite direction to the cooling chamber 110 by the pressure generated when the door 120 is closed, and returns to the original position after reducing the pressure difference with the outside, so that a large It is possible to close the door 120 without applying any force, and it is possible to alleviate the impact generated when the door 120 is in close contact with the front end of the main body 100 .

On the other hand, the supercooling device according to an embodiment of the present invention includes one or more passages and a pressure control plate 900 for reducing the pressure difference between the pressure in the cooling chamber and the outside when the door 120 is opened or closed as shown in FIGS. 12 and 13 . ) may be further included.

The passage horizontally communicates the cooling chamber 110 and the outside, and the inside of the passage maintains a state blocked by the pressure control plate 900 so that air does not pass therethrough. Here, the pressure regulating plate 900 may use a material (rubber, etc.) that can be elastically deformed by pressure, may have a disk shape with an edge forming a circumference, and an edge of the pressure regulating plate 900 may have a shape corresponding to the inner circumferential surface of the passage can be combined with

For example, when the door 120 is rotated in the opening direction, as shown in FIG. 12 , a pressure pulling in the opening direction of the door 120 is applied, so that a pressure difference between the cooling chamber 110 and the external space occurs. At this time, the pressure regulating plate 900 is elastically deformed in the direction of the cooling chamber 110 by the pressure acting on the passage and protrudes, and then restored to its original shape, and the cooling chamber 110 by the elastic deformation of the pressure regulating plate 900 . Since the pressure of the is momentarily reduced, it is possible to reduce the pressure difference between the cooling chamber 110 and the external space.

That is, since the pressure regulating plate 900 is elastically deformed by the pressure generated when the door 120 is opened and returns to the original position after reducing the pressure difference with the outside, the door 120 can be moved without applying a large force. It can be opened, and the shock generated when the door 120 is spaced apart from the front end of the body 100 can be alleviated.

On the other hand, when the door 120 is rotated in the closing direction, as shown in FIG. 13 , a pressure pushing the door 120 in the closing direction is applied, so that a pressure difference between the cooling chamber 110 and the external space occurs. At this time, the pressure regulating plate 900 is elastically deformed in the opposite direction to the cooling chamber 110 by the pressure acting on the passage and protrudes, and then is restored to its original shape, and the cooling chamber is elastically deformed by the pressure regulating plate 900 . Since the pressure of 110 is momentarily reduced, the pressure difference between the cooling chamber 110 and the external space can be reduced.

That is, since the pressure regulating plate 900 is elastically deformed by the pressure generated when the door 120 is closed and returns to the original position after reducing the pressure difference with the outside, the door 120 can be moved without applying a large force. It can be closed, and the impact generated when the door 120 is in close contact with the front end of the main body 100 can be alleviated.

As a result, the present invention can directly deliver cold air to the liquor container 10 in which the temperature of the cooling chamber can be maintained at a temperature suitable for supercooling with low power, and the temperature of the cooling chamber 110 is the reference temperature Since it is kept constant, it is possible to prevent the beverage from reaching the supercooled state or from freezing, and since the supercooled state of the beverage is kept constant, the beverage can be stored in an optimal state.

In addition, the present invention can improve the temperature control performance and efficiency by using the auxiliary cooling unit 700 to finely control the temperature with low power, and when the pressure control unit 800 or the pressure control plate 900 is applied, the door Since the opening and closing of 120 is easy, the convenience of use can be improved, and the shock transmitted to the body 100 when the door 120 is opened and closed can be alleviated, so that the supercooled state of the beverage is not changed.
