The present invention relates to a wine cell, and more particularly, to a wine cell control structure and a control method for allowing the wine cell to operate continuously by eliminating the need for a separate defrosting operation.

Generally, the environment in which wine is stored is well ventilated, the temperature / humidity change is small, and a quiet place without vibration is preferable. As such an environment, there have been underground warehouses, oysters and basement layers. However, since it is very difficult to find such a natural environment, a wine cellar has been introduced as an electronic device for artificially creating such an environment.

On the other hand, in order to obtain an optimal flavor by the wine cellar, it is important to implement a suitable temperature environment, especially among the above-mentioned conditions such as temperature, humidity, ventilation, etc., in order to store wine, an appropriate temperature is approximately It is 10-18 degreeC, and when it is white wine, it is known that it is about 4-10 degreeC. The present invention relates to a structure of a wine cell that can be implemented such a suitable wine storage temperature.

On the other hand, the conventional wine cell is a refrigeration system is implemented to perform refrigerated storage, and when the refrigeration system is continuously operated, defrosting operation to remove the frost stuck to the evaporator is intermittently performed.

However, in order to perform the defrosting operation, there is a disadvantage in that an additional defrost heater must be additionally installed. In addition, since the temperature of the wine storage space is increased during the defrosting operation, there is a problem that the function of the wine cellar in which the proper temperature is continuously maintained is lost.

In addition, since cold air is lost by the heat applied during the defrosting operation, and the refrigeration system is operated more strongly as the lost cold air, energy efficiency is inferior.

The present invention is proposed in order to solve the above problems, in view of the temperature is stored in the wine is different from the usual freezers and refrigerators, defrosting operation is not required, even if the defrosting on the surface of the evaporator can be removed. An object of the present invention is to propose a control structure and a control method of a wine cell.

In addition, it is an object of the present invention to propose a control structure and a control method of the wine cell that can reduce the power consumption and manufacturing cost by eliminating the defrosting operation and the defrost heater for it.

The control structure of the wine cellar according to the present invention for achieving the above object is a temperature sensor for measuring the temperature of the wine storage space; An evaporator temperature sensor for measuring the temperature of the evaporator in the refrigeration system; A compressor driver for operating the compressor of the refrigeration system; Three sides to control the supply of the refrigerant supplied to the expansion side of the refrigeration system; A first expansion device and a second expansion device in which the refrigerant supplied through the three sides is expanded; And a controller for restarting the compressor driving unit when the temperature of the evaporator temperature sensor is higher than a predetermined temperature by the temperature measured by the temperature sensor and the evaporator temperature sensor.

In the wine cell control method according to another aspect of the present invention, after the compressor driving unit is stopped in the refrigeration system of the wine cell, the temperature of the storage space is higher than the first set temperature, the temperature of the evaporator for cooling the storage space is constant. Only when the temperature is higher is the compressor drive restarted.

By the control structure and control method of the wine cell as proposed, it is possible to obtain the effect that the wine can be stored at the optimum temperature for each type of wine. In addition, since the defrosting operation is not required separately, the user's convenience can be enhanced, and manufacturing cost and power consumption can be reduced.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. However, the spirit of the present invention is not limited to the embodiments in which the present invention is presented, and those skilled in the art who understand the spirit of the present invention can easily make other embodiments by adding, changing, deleting, and adding components within the scope of the same idea. It may be proposed, but this will also fall within the scope of the present invention.

1 is a perspective view of a wine cellar according to the spirit of the present invention.

Referring to FIG. 1, the wine cellar 1 of the present invention has a predetermined inside of a case in which a predetermined heat insulator is interposed between the outer case 2 of the outside of the wine cell and the outer case 2. Inner case (5) and the inner space of the inner case 5 is provided with a storage space is divided into the upper compartment (8), the lower compartment (10) and the middle compartment (9) so that the interior of the wine compartment is divided An upper barrier 6 and a lower barrier 7 and a door 3 are selectively shielded in front of the inner case 5 so that the temperature of the inner space is properly maintained. In addition, the door 3 is further formed with a transparent window 4 to allow the user to easily see the interior of the wine cell (1). In another aspect, it can be understood that the body of the wine cellar is formed by the outer case 2 and the inner case 5, and the body of the wine cellar is opened by the door 3.

As described above, the wine accommodating space formed inside the wine cell may be divided into an upper compartment 8, a middle compartment 9, and a lower compartment 10, and different types of wine may be stored in each accommodation space. . For example, the upper compartment 8, which is formed with a relatively high temperature, may store utensils such as red wine and wine glasses that are stored at a relatively high temperature, and the middle compartment 9 may store red wine, and a relatively low temperature lower hakan ( 10) white wine can be stored at a relatively low temperature. As such, the internal space of the wine cellar is partitioned by temperature because it is good for the wine to ripen and different storage temperature according to the type of wine, it is possible to increase the taste of consumers. In addition, since the temperature can be efficiently maintained according to the storage location of the wine, the energy consumption efficiency can also be increased.

Hereinafter, each configuration in which the temperature of the wine cell is controlled will be described in detail. 2 is a view showing in detail the back structure of the wine cellar. Referring to Figure 2, the wine cell of the present invention, the cooling system and the heating system are formed separately. First, the cooling system is placed inside the machine room 20 so that the refrigerant is compressed, the condenser 12 in which the refrigerant compressed by the compressor 11 is condensed, and the condensed refrigerant is branched and supplied. A three-way side (80), a first expansion device (13) and a second expansion device (14) for expanding the refrigerant compressed in the condenser (12), and the expansion in the first expansion device (13) An upper column evaporator 15 and a middle column evaporator 16 for allowing the refrigerant to evaporate in the upper compartment 8 and the middle compartment 9, and a lower condenser 17 for evaporating the refrigerant expanded in the second expansion device 14 are included. . The amount of the coolant supplied to the expansion devices 13 and 14 may be controlled by the three-way side 80.

In detail, the condenser is in contact with the outer case 5 side of the back of the wine cell 1, so that the heat can be discharged quickly. And, the evaporator 15, 16, 17 is in contact with the inner case 5 side, so that cold air can be easily supplied to the interior of the wine cell.

In brief description of the operation of the refrigeration system, the refrigerant compressed in the compressor 11 and condensed in the condenser 12 is expanded in the expansion valves 13 and 14 after the flow rate is controlled by the three-way valve 80. During the passage of the evaporators 15, 16, 17, cold air is supplied into the wine cell 1.

In detail, the first expansion device 13 allows cold air to be supplied to the upper compartment 8 and the middle compartment 9, and the second expansion device 14 allows cold air to be supplied to the lower compartment 10. In addition, since the refrigerant evaporated in the upper column evaporator 15 is subsequently evaporated in the middle column evaporator 16, the middle column evaporator 16 may be maintained at a somewhat higher temperature than the upper column evaporator 15. However, the shape and structure of the upper column evaporator 15 and the middle column evaporator 16 are changed according to the structural characteristics of the wine cell, so that the temperature of the upper column 8 and the middle column 9 may be maintained the same. Of course, the upper column evaporator 15 allows cold air to be supplied to the upper compartment 8, and the middle column evaporator 16 allows cold air to be supplied to the middle compartment 9. In addition, the evaporator temperature sensor 40 is formed in the upper evaporator 15 so that the temperature of the upper evaporator 15 is measured. The evaporator temperature sensor 40 may be formed in contact with the upper evaporator 15, or may be formed apart if the temperature of the upper evaporator 15 can be accurately measured.

The evaporator temperature sensor 40 is shown as being formed in the upper column evaporator 15, but also formed in the middle column evaporator 17 and the lower column evaporator 17, respectively, so that the temperature of the evaporators 15, 16, 17 is It may be measured separately and delivered to the control unit of the wine cellar.

In addition, the refrigerant evaporated by the evaporators 15, 16, 17 and absorbed the heat in the wine cell is introduced again into the compressor 11 after being combined.

On the other hand, the opening degree of the expansion device (13) 14 is adjusted to control the flow rate of refrigerant into each of the evaporators (15) (16) (17), thereby adjusting the upper (8), middle (9) and the lower (10). The temperature can be kept different from each other. For example, the opening degree of the second expansion device 14 is kept larger than the opening degree of the first expansion device 13, so that the temperature of the lower row 10 is kept lower by the lower row evaporator 17 than the other chambers. Can be. As such, the temperature of the hakan 10 placed below the inside of the wine cell is kept lower than that of the middle compartment 9 and the upper compartment 8 so that convection that may occur inside the wine cell is suppressed, thereby using energy. Efficiency can be enhanced. And, as described above, by allowing the internal temperature of the wine cell to be controlled differently for each zone, the type of wine that can be accommodated can be distinguished.

On the other hand, the above-mentioned refrigeration system is a system that is operated when the internal temperature of the wine cell must be kept lower than the external temperature, and, if the internal temperature of the wine cell should be kept higher than the external temperature, the heating system should be operated Hereinafter, such a heating system will be described.

In the heating system of the wine cell according to the present invention, a heating device is separately formed in the upper compartment 8, the middle compartment 9, and the lower compartment 10 so that power applied from the outside is introduced, and each heater is an outer case. By relatively contacting the inner case 5 side between (2) and the inner case 5, heat can be dissipated easily inside the wine cell. First, the upper column heater 18 built in the rear wall of the wine cell so that the heat is applied to the upper cell 8 and the middle cell heater built in the rear wall of the wine cell so that the heat is applied to the middle cell 9. (19) and a hakan heater (see 21 in FIG. 3) which is built in the side wall of the wine cell in order to allow the hakan to apply heat. Since the heaters 18, 19 and 21 are all embedded in the wall of the wine cell and are not visible from the outside, the aesthetics of the user can be enhanced. Then, the heaters 18, 19, 21 are embedded in the upper wall 8, the middle car 9, and the lower wall of the lower car 10, so that heat is constrained by the convection phenomenon. 9) to be circulated to the entire internal space of the (10).

In detail, the upper compartment heater 18 and the middle compartment heater 19 are formed on the close side of the inner case 5 on the rear wall of the wine cell so that heat is accurately applied to the inside of the wine cell. In addition, the hakan heater 21 is embedded in the side wall of the wine cell because there is a restriction in the installation space of the rear wall by the machine room 20. Installation of the Hakan heater 21 will be clearly understood by FIG.

The heating system as shown is a device in which the operation starts when the inside of the wine cell is to be maintained at a high temperature compared to the outside, so that the temperature can be controlled differently for each compartment (8) (9) (10). For example, since white wine must be placed in the hakan 10 and kept at a relatively low temperature, the hakan heater 21 is controlled so that a relatively small amount of heat is applied. In addition, since the red wine should be placed in the upper compartment 8 and / or the middle compartment 9 and maintained at a relatively high temperature, the upper compartment heater 18 and the middle compartment heater 19 may be applied with a relatively large amount of heat.

4 is a diagram illustrating a barrier in which an internal space of a wine cell is partitioned.

Referring to FIG. 4, the barrier includes an upper barrier 6 for partitioning the upper compartment 8 and a middle compartment 9, and a lower barrier 7 for partitioning the middle compartment 9 and the lower compartment 10. Inside each barrier there is an insulating foam (foam) to block the movement of heat and cold air in each compartment. Then, it is placed in the horizontal direction so that the wine can be placed on the upper side thereof. Of course, the wine may not only be placed on the upper side of the barriers 6 and 7 but also in a separate rack.

In detail, the upper barrier 6 is formed in a horizontal direction adjacent to the lower side of the upper chamber heater 18, and the lower barrier 7 is formed in a horizontal direction adjacent to the lower side of the middle chamber heater 19. Can be. As the barriers 6 and 7 are positioned in this way, the heat transferred from the upper compartment heater 18 may be circulated widely in the upper space of the upper compartment 8, and the heat transferred from the intermediate chamber heater 19. May be circulated widely in the entire space of the middle compartment (9). Of course, since the hakan heater 21 is placed on the lower side of the hakan 10, heat transferred from the hakan heater 21 can be circulated widely in the entire space of the hakan 10.

In addition, inside the barriers 6 and 7, temperature sensors 23 and 24 may be formed to detect an internal temperature of each compartment 8, 9 and 10, in detail, an upper barrier. That is, the first temperature sensor 23 lying on the lower side of (6) and the second temperature sensor 24 lying on the lower side of the lower barrier 7. The temperature of the upper compartment 8 and the middle compartment 9 is measured by the first temperature sensor 23, and the temperature of the lower compartment 10 is measured by the second temperature sensor 24, and then transferred to the controller of the wine cell. The refrigeration system and the heating system are selectively operated to allow the internal temperature of the wine cell to be manipulated.

5 is a block diagram illustrating a refrigeration system according to the present invention.

Referring to FIG. 5, the refrigeration system of the wine cell according to the present invention includes a compressor 11 for compressing the refrigerant, a condenser 12 for condensing the refrigerant, and a triangular valve 80 for branching the supply of the refrigerant. ), An expansion device (13) (14) to allow the refrigerant to expand, and evaporators (15) (16) (17) to allow the refrigerant to evaporate. On the other hand, the wine cell of the present invention is characterized in that the temperature of the upper compartment (8) and the middle compartment (9) of the refrigeration system, and the temperature of the lower compartment (10) are individually controlled to be kept in a low temperature state. To this end, a first expansion device 13 for allowing the refrigerant to flow to the upper column evaporator 15 and the middle column evaporator 16 side, and a second expansion device 14 for allowing the refrigerant to flow to the lower column evaporator 17 side. .

The opening degree of the first expansion device 13 is adjusted by the refrigeration system, so that the low-temperature state of the upper compartment 8 and the middle compartment 9 can be properly maintained, and the opening degree of the second expansion device 14 is adjusted. Thus, the low temperature state of the hakan 10 can be properly maintained.

6 is an overall control block diagram of the wine cellar according to the present invention.

Referring to FIG. 6, the wine cell according to the present invention includes an operation unit 31 for a user to perform an operation, the first temperature sensor 23 and a second temperature sensor 24 for sensing a temperature inside the wine cell. , An evaporator temperature sensor 40 for measuring the temperature of the evaporator, a heater driver 32 for driving the heating system as described above, a compressor driver 33 for driving the compressor of the refrigeration system, and the three way Three-way drive unit 34 to control the side 80 to control the amount of refrigerant passing through each expansion device 13, 14, and the control unit 30 to control the overall operating state of the wine cell ) Is included.

Referring to the control block diagram illustrating the operation of the wine cell, the operation of the wine cell is started by the user operating the operation unit 31. In operation of operating the operation unit 31, an operation of designating a target temperature inside the wine cell is accompanied.

In order to reach the target temperature set by the user during the above operation, the temperature inside the wine cell is continuously measured using the first temperature sensor 23 and the second temperature sensor 24, and the sensor 23 is used. The heater driver 32, the compressor driver 33, and the three-way driver 34 are selectively operated by comparing the difference between the measured temperature and the target temperature measured by 24. For example, when the measured temperature is lower than the target temperature, the heater driver 32 is operated to increase the temperature of the wine cell. When the measured temperature is higher than the target temperature, the compressor driver 33 and the three-way driver 34 are operated. To work. In addition, the three-way drive unit 34 controls the amount of refrigerant flowing into the first expansion device 13 and the second expansion device 14, respectively, so that the temperature inside the wine cell is increased in the compartments 8 and 9. The temperature is appropriately controlled for each position of the (10).

In addition, in the present invention, since the wine storage space is cooled by the cold air delivered into the refrigerator in the buried state as the buried type, the evaporator must pass through a heat insulating material and an inner case of a predetermined thickness in order to be transferred to the wine storage space. Therefore, the temperature of the evaporator must be much lowered below a certain level below zero, but the temperature of the wine cell can be kept at an appropriately low temperature. However, the temperature of the wine storage space is in the range of 4 ℃ ~ 18 ℃, it is preferable to maintain the temperature higher than the temperature of the normal refrigerator, under such conditions, without a separate defrosting operation, the sex is not stuck to the surface of the evaporator The control method of the wine cellar can be derived.

For example, the temperature of the evaporator is measured by the evaporator temperature sensor 40 in order to prevent the stickiness of the evaporator from sticking to the surfaces of the evaporators 15, 16 and 17 in the wine cell, thereby preventing the efficiency of the evaporator from dropping. Only when over temperature is detected by the controller 30, the compressor drive 33 and the tri-directional drive 34 are operated. By controlling the compressor driving unit 33 and the three-way driving unit 34 in this way, since the frost is not originally adhered to the surface of the evaporator, an additional defrosting operation is not required.

Hereinafter, a method of controlling a wine cell that does not require defrosting operation will be described in detail. FIG. 7 illustrates a flow of a method of controlling a wine cell according to the present invention.

Referring to FIG. 7, the control method of the wine cell according to the present invention starts with the compressor driving unit 33 and / or the three-way driving unit 34 stopped first (St 110). Of course, the stopped state of the compressor can be easily guessed when the temperature in the chamber, which is the wine storage space sensed by the temperature sensors 23 and 24, drops below a certain level, and the supply of cold air is stopped.

In order to operate the compressor driver 33 again, the compressor driving unit 33 undergoes a multi-step determination process. First, it is determined whether or not the internal temperature is higher than the first set temperature (St 111), and if it is large, the process proceeds to the next step, and if it is not large, the compressor driving unit 33 and / or the three-way driving unit 34 continue to stop. do. When the internal temperature is higher than the first set temperature, it is again determined whether or not the temperature of the evaporator detected by the evaporator temperature sensor 40 is greater than a predetermined temperature (St 112). (St 113) otherwise the compressor drive 33 is kept stationary. In this way, even when the temperature inside the high temperature is greater than the first set temperature, when the evaporator temperature is not higher than a predetermined temperature, the compressor driving unit 33 is not operated to melt the frost that may be stuck on the surface of the evaporator. By operating the wine cellar as described above, it is possible to obtain the advantage that the wine cell does not need a separate defrosting operation.

At this time, the temperature compared with the temperature of the evaporator in the comparison step (St 112) of the evaporator temperature is the temperature at which the frost can be melted within the range of the temperature of the image, the temperature in the wine storage space is not too high range It can be determined by the experiment in, according to the experiment, the range of 2 ℃ ~ 5 ℃ can be proposed preferably, more preferably 3 ℃. When the temperature is high outside the above-mentioned temperature range, the temperature of the storage space may be so high that the flavor of the wine may be lost, and if it is too low, the frost may adhere to the surface of the evaporator.

After the compressor is started (St 113), it is again determined whether or not the internal temperature is lower than the second set temperature (St 114). When the internal temperature is low, the compressor driving unit 33 is stopped and the high In this case, the compressor driving unit 33 is continuously operated (St 115).

On the other hand, the state in which the compressor drive unit 33 is stopped is a state in which the operation of the refrigeration system for all of the compartments 8, 9 and 10 is stopped, and the compartments 8, 9 and 10 are stopped. If only one of the cold air is to be supplied, the three-way drive unit 34 is controlled by the compressor driving unit 33 is operated, so that the refrigerant is supplied or supplied to a specific evaporator (15, 16, 17) You can prevent it. For example, when the refrigerant is to be supplied only to the hakan evaporator 17, the three-way drive unit 34 is controlled to supply the first expansion device 13 while the compressor drive unit 33 is operated. The opening can be adjusted so that the flow path is completely closed, and the opening can be adjusted to open to a certain level only by the supply flow path to the second expansion device 14.

By the control structure and the control method of the wine cell as described so that the declination adhered to the surface of the evaporator in the refrigeration system is essentially eliminated, there is an advantage that no separate defrosting operation is required. As such, it is possible to eliminate the need for a separate defrosting operation in the case of the wine cellar, since the internal temperature of the wine cellar maintains a range of 4 ° C to 18 ° C, which is not so low, unlike a general refrigerator.

According to the present invention, in the case of a wine cell, a separate defrosting operation is not required, but it is possible to obtain an advantage that the frost is not naturally frosted on the surface of the evaporator.

In addition, since the defrosting operation and the defrost heater for it is not required, there is an advantage that the power consumption is reduced and the manufacturing cost is reduced.
