Operation Control Method of Kimchi Storage {CONTROL METHOD FOR OPERATION OF KIMCH'I STORE HOUSE}

The present invention relates to an operation control method of the kimchi storage, and more particularly to an operation control method of the kimchi storage that can minimize the noise generated during the operation of the kimchi storage.

In general, in order to store frozen foods, refrigerated foods, and fermented foods (for example, kimchi) at a temperature suitable for storing them, a refrigerator having a freezing compartment and a refrigerating compartment may be used. Mainly used.

However, when the refrigerated food and the fermented food are stored together in the refrigerator, the odor is generated in the refrigerating chamber due to the smell of the fermented food. As the number of refrigerated foods and fermented foods to be refrigerated can increase, there is a need to store relatively bulky fermented foods (kimchi) in separate storage.

In addition, kimchi can be properly seasoned by burying it in the ground and ripening it at the proper temperature conditions.However, due to the limitations of the residential environment such as apartments and townhouses, it is difficult to keep it in the ground. It is difficult.

Recently, in order to solve the above problems, research on kimchi storage that can store kimchi in a separate storage space, rather than a refrigerator, has been variously studied in various technical fields related thereto. As shown in FIG.

The appearance of the kimchi storage as described above is shown in Figure 1, a plurality of interior of the kimchi, that is, the storage of kimchi, that is in the left and the inside of the wogo (右 庫內) as shown in FIG. A pair of doors, that is, a left inner door 21 and an inner right door which are formed on the upper part of the main body 10 via a hinge to open and close the formed main body 10 and the upper and lower left and right sides thereof, 22).

On both sides of the main body 10, the handle 30 is installed so that the user can easily pull the main body 10 when moving the kimchi storage, and the main body (on the bottom surface of the main body 10) 10) is provided with a horizontal adjustment leg 40 for adjusting the horizontal, the bottom portion of the bottom surface of the main body 10 is attached to the wheel 50 that is rotated when moving the kimchi storage.

On a predetermined portion of the upper surface of the left in-door door 21 and the right in-door door 22, a pair of key input units, i.e., a left in-high key input unit 61, can be freely selected and input according to a user's preference. And an in-house key input unit 62 are provided.

Here, the inside of the main body 10, as shown in Figure 2, the inside of the left height 11 and the right height 12 and the machine room 13 is formed, the inside of the left height 11 and the right height 12 On each wall of the), the left and right in-evaporator 76 and the in-ego evaporator 77 which generate cold air by using the latent heat of evaporation when the refrigerant is evaporated, and the in-left temperature sensor 80 which senses the temperature in each store and An in-high temperature sensor 81, an in-high left heater 78 and an in-high heater 79 that generate heat are provided.

In the inside of the machine room 13, a compressor 70 for compressing a refrigerant gas at high temperature and high pressure, and a condenser 71 for condensing the refrigerant compressed at high temperature and high pressure through the compressor 70 to a liquid refrigerant at high pressure and room temperature. Then, the liquid refrigerant condensed in the condenser 71 is supplied via the left high solenoid valve 72 and the right high solenoid valve 73 to reduce the pressure to low pressure, respectively, and then the above-described left high internal evaporator 76 and the high cold inside Cooling that cools the condenser 71 and the compressor 70 by blowing the left inner capillary tube 74 and the right upper capillary tube 75 supplied to the evaporator 77 and cold air to the condenser 71 and the compressor 70. The fan motor 82 is installed.

The operation process of the kimchi storage configured as described above is as follows.

First, the user stores kimchi in the left height 11 and the right height 12, and then operates the left height key input 61 and the right height key input 62 to operate the left height 11 and right height 12. When the operation mode (mature mode and the refrigerated storage mode, etc.) is selected, a key signal corresponding to the operation mode selected by the user is omitted from the left height key input section 61 and the right height key input section 62. The controller determines the operation mode of each interior selected by the user based on the key signals input from the left height inside key input unit 61 and the right height inside key input unit 62 and operates the kimchi storage according to the determined driving mode. .

For example, in the ripening mode, if the temperature in the left height 11 is less than or equal to the heater driving temperature, the inside left height heater 78 is driven by the control unit so that the temperature in the left height 11 is increased, and the left height 11 is increased. If the temperature is equal to or higher than the heater driving stop temperature, the driving of the left high-altitude heater 78 is stopped by the control unit and the temperature of the high-altitude left 11 is lowered, so that the temperature of the high-altitude 11 is set to a predetermined ripening temperature (eg, For example, at the time of rapid ripening is maintained at about 23 ± 2 ℃, usually at about 7 ± 2 ℃) and stored kimchi stored in the inside of the high school (11), the operating process of the inside of the high school (12) also in the left high (11) Same as the case of).

On the other hand, when refrigerated storage, as can be seen with reference to Figure 3, if the temperature in the upper left 11 is greater than the refrigerant circulation temperature, the inner high solenoid valve 72 is opened by the control unit, the inside of the left high 11 If the temperature is equal to or lower than the refrigerant circulation stop temperature, the left insole high solenoid valve 73 is closed, and the inside of the right height 12 is the same as in the left height 11.

At this time, the compressor 70 is driven by the control unit in a state in which at least one of the left inner solenoid valve 72 and the right inner solenoid valve 73 is opened, the refrigerant gas is driven when the compressor 70 is driven. Compressed to a high temperature and high pressure in the compressor (70) and then condensed into a liquid refrigerant of a high pressure room temperature through the condenser 71, the liquid refrigerant condensed in the condenser 71 is reduced to a low pressure through a capillary tube on the side of the valve opening It is then vaporized inside the evaporator in the furnace.

As the low-pressure liquid refrigerant is evaporated inside the evaporator as described above, as the air around the evaporator is heat-exchanged with cold air by latent heat of evaporation, the inside of the evaporator is cooled to store the kimchi stored in the refrigerator.

Then, the driving of the compressor 70 is stopped in a state where both the left high solenoid valve 72 and the right high solenoid valve 73 are closed.

On the other hand, in the case of performing the refrigeration storage operation of only one of the left height 11 and the right height 12, as shown in Figure 4, the refrigeration storage mode is selected according to the temperature in the selected refrigerator The solenoid valve inside is opened and closed, and the compressor 70 is turned on / off in accordance with the opening and closing of the solenoid valve.

By the way, the kimchi storage as described above, while the various components of the operation inside the operation of the various mechanical noises are generated, in particular, a lot of noise is generated from the compressor and the solenoid valves, of which the solenoid valve is opened or closed operation Since the noise generated at the time is the greatest, it is desirable to reduce the number of opening and closing operations of the solenoid valve to reduce the overall noise of the kimchi storage.

Accordingly, the present invention has been made in view of the above, and in the case of an operating condition for circulating a refrigerant only in one of a plurality of interiors, only the compressor is turned on / off with the refrigerant supply valve in the interior open. It is an object of the present invention to provide an operation control method of a kimchi storage, which can minimize the frequency of noise caused by opening and closing the valve.

The description will be omitted.

In FIG. 5, the left in-stock key input unit 100 includes a plurality of selection buttons for selecting and inputting an operation mode (for example, a refrigerated storage mode and a ripening mode) of the in-stock 11. When the button is operated, a key signal corresponding to the operated selection button is input to the controller 140.

The in-house key input unit 110 includes a plurality of selection buttons for selecting and inputting an operation mode (for example, a refrigerated storage mode and a maturing mode) of the in-house 12, and when the user operates the select button. The key signal corresponding to the operated selection button is input to the controller 140.

The temperature in the left height sensor 120 senses the temperature of the inside of the left height 11 and inputs a temperature signal corresponding to the detected temperature to the control unit 140, the temperature inside the right height sensor 130 is in the height Detects the temperature of 12 and inputs a temperature signal corresponding to the detected temperature to the controller 140.

The control unit 140 according to the operation mode of the in-left 11 or in-high 12 selected by the user through the inside of the left height key input unit 100 or the right height inside key input unit 110 and the inside of the left height. The solenoid valve 72 or the in-go solenoid valve 73 is selectively driven to drive the inside of the left height 11 or the in-go height 12.

The compressor driving unit 150 applies power to the compressor 70 according to a control signal from the controller 140 to drive the compressor 70, and the compressor 70 compresses the refrigerant gas at a high temperature and high pressure to condenser 71. To be discharged.

The solenoid valve driving unit 160 opens and closes the left inner solenoid valve 72 or the right inner solenoid valve 73 according to a control signal from the control unit 140.

An operation example of the present invention through the hardware configured as described above will be described in detail with reference to FIGS. 5 to 7.

First, when power is applied to each part of the kimchi storage from a predetermined power supply source (for example, a commercial AC power supply), the control unit 140 is initialized, and the initialized control unit 140 is the left height key input unit 100 and the right height. Switched to the standby mode for receiving a key signal from the inner key input unit 110, the temperature in the upper left 11 and the inner right 12 from the temperature sensor 120 and the inside temperature inside the high temperature sensor 130 The temperature signals corresponding to the respective signals are output to the controller 140 (S10).

In this case, when the user operates the selection buttons provided in the left in-height key input unit 100 and the right in-height key input part 110 to set the operation mode of the left-height 11 and the in-height 12 to the refrigerated storage mode. The key signal corresponding to the selection button selected by the user is input to the controller 140 from the left height key input unit 100 and the right height key input unit 110.

The control unit 140 selects the operation mode of the in-left 11 and in-high 12 selected by the user by the key signals input from the in-left height key input unit 100 and the in-high height key input unit 110. If it is determined whether the operation mode (S20), and the operation mode of the left 11 and the right 12 selected by the user is not the 'cold storage mode' other operation mode selected by the user (for example, ripening mode ).

If the operation mode of the left height 11 and the right height 12 selected by the user in the step S20 is the 'cold storage mode', the controller 140 controls the left height key input unit 100 and the height height. The key signal input from the inner key input unit 110 determines whether the user has selected the refrigerated storage mode for both the left height 11 and the right height 12 (S30).

As a result of the determination in step S30, when the refrigerated storage mode is selected for both the inside of the left height 11 and the inside of the right height 12, the controller 140 controls the temperature inside the left height temperature sensing unit 120 and the temperature inside the right height storage unit ( 130 in the left height solenoid valve 72 according to the temperature of the left height 11 and the right height 12 sensed by sensing the temperature in the left height 11 and the right height 12 by the temperature signal applied from 130 and Optionally opening and closing the solenoid valve 73 in the wogo (S40).

That is, when the temperature in the upper left 11 is higher than the preset refrigerant circulation temperature Tmax (for example, about 1 ° C.), the inner left solenoid valve 72 is opened so that the refrigerant is circulated to the lower left evaporator 76. When the temperature in the upper left 11 is less than or equal to a predetermined refrigerant circulation stop temperature Tmin (for example, about -3 ° C.), the inner left solenoid valve 72 is stopped so that the refrigerant circulation in the lower left evaporator 76 is stopped. Close it.

In addition, if the temperature of the in-house 12 is greater than or equal to the refrigerant circulation temperature Tmax, the in-house solenoid valve 73 is opened so that the refrigerant is circulated to the in-house evaporator 77, and the temperature of the in-house 12 is If the refrigerant circulation stop temperature (Tmin) or less, the in-sole solenoid valve 73 is closed so that the refrigerant circulation of the in-evaporator evaporator 77 is stopped.

At the same time, the control unit 140 drives the compressor 70 according to the open / closed state of the left inner solenoid valve 72 and the right inner solenoid valve 73 (S50).

That is, when at least one of the left high solenoid valve 72 and the right high solenoid valve 73 is opened, the compressor 70 is operated, and the left high solenoid valve 72 and the right high solenoid valve 73 are operated. If all are closed, the compressor 70 is stopped.

For example, when the temperature in the left height 11 of the left height 11 and the right height 12 is greater than or equal to the refrigerant circulation temperature Tmax, the left height solenoid valve 72 is opened, and after a predetermined time, the compressor ( 70 is driven.

The refrigerant gas is compressed to a high temperature and high pressure through the driven compressor (70) and supplied to the condenser (71), and the high temperature and high pressure refrigerant gas supplied from the compressor (70) is condensed into a liquid refrigerant at high pressure and room temperature in the condenser (71). Then, it is supplied to the in-left capillary tube 74 through the left in-sole solenoid valve 72.

The high-pressure room temperature liquid refrigerant supplied from the condenser 71 through the in-stock left solenoid valve 72 is decompressed to low pressure through the in-stock left capillary 74, and then supplied to the in-stock left evaporator 76 to supply the left-side evaporator ( It is vaporized inside 76).

When the liquid refrigerant is evaporated in the interior of the upper left evaporator 76, the heat exchange is performed by latent latent heat of evaporation, thereby cooling the internal air in the upper left 11, thereby storing the kimchi stored in the lower left 11 refrigerated.

At this time, when the temperature of the in-house 12 becomes greater than or equal to the refrigerant circulation temperature Tmax, the in-house solenoid valve 73 is opened, and the high-pressure room temperature liquid refrigerant condensed in the condenser 71 is compressed from the compressor 70. Is supplied to the in-go capillary tube 75 through the in-go-sole solenoid valve 73.

The liquid refrigerant of high pressure and room temperature supplied from the condenser 71 through the in-house solenoid valve 73 is depressurized to low pressure through the in-house capillary tube 75, and then supplied to the in-house evaporator 77 to supply the in-house evaporator ( 77) is vaporized inside.

When the liquid refrigerant is evaporated in the interior of the evaporator 77, the heat exchange is performed by latent latent heat of evaporation, so that the internal air of the interior 12 is cooled, and the kimchi stored in the interior 12 is refrigerated.

Then, when the temperatures of the upper left 11 and the lower 12 are both lower than the refrigerant circulation stop temperature Tmin, driving of the compressor 70 is stopped, and after a predetermined time, the left upper solenoid valve 72 and the lower height Inner solenoid valves 73 are closed respectively.

Next, the control unit 140 determines whether a new key signal for changing the operation mode is input from the left height key input unit 100 or the right height key input unit 110 (S60), and the result of the determination changes the operation mode. When a new key signal is inputted, the process returns to the step S20 to determine the operation mode changed by the user.

If a new key signal for changing the operation mode is not input from the left high key input unit 100 or the right high key input unit 110 as a result of the determination in step S60, the steps S40 and S50 are continued. Perform.

On the other hand, when the user selects to carry out the refrigeration storage operation of only one of the left in the storehouse 11 and the right storehouse 12 as a result of the determination in the step (S30), the control unit 140 performs the refrigerated storage operation The solenoid valve set in the chamber is opened (S70), and the user sets the refrigerator storage operation to be performed by the user by a temperature signal applied from the left inner temperature sensor 120 or the upper temperature sensor 130. Sensing the temperature and driving the compressor 70 in accordance with the detected temperature in the furnace (S80).

For example, as can be seen with reference to Figure 7, when the user selects only the in-chamber 12 in the cold storage mode, the in-go solenoid valve 73 is first opened.

Then, when the temperature in the chamber 12 is greater than or equal to the refrigerant circulation temperature Tmax, the compressor 70 is operated. The refrigerant gas is compressed to a high temperature and high pressure through the driven compressor 70 to the condenser 71. The refrigerant gas of the high temperature and high pressure supplied from the compressor 70 is condensed into the liquid refrigerant of high pressure and room temperature in the condenser 71, and then, through the open in-going solenoid valve 73 to the in-go capillary tube 75. Supplied.

The liquid refrigerant of high pressure and room temperature supplied from the condenser 71 through the in-house solenoid valve 73 is depressurized to low pressure through the in-house capillary tube 75, and then supplied to the in-house evaporator 77 to supply the in-house evaporator ( 77) is vaporized inside.

When the liquid refrigerant is evaporated in the interior of the evaporator 77, the heat exchange is carried out by latent latent heat of evaporation, thereby cooling the internal air of the inside of the well 12, whereby the kimchi stored in the well 12 is refrigerated.

When the temperature in the rain chamber 12 is equal to or lower than the refrigerant circulation stop temperature Tmin, the driving of the compressor 70 is stopped and the circulation of the refrigerant is stopped. However, the insole high pressure solenoid valve 73 continuously maintains an open state.

Next, the control unit 140 determines whether a new key signal for changing the operation mode is input from the left height key input unit 100 or the right height key input unit 110 (S90), and the result of the change of the operation mode is determined. When a new key signal is inputted, the process returns to the step S20 to determine the operation mode changed by the user.

If a new key signal for changing the operation mode is not input from the left high key input unit 100 or the right high key input unit 110 as a result of the determination in step S90, the steps S70 and S80 are continued. Perform.

As described above, according to the present invention, when the refrigerant is circulated only in one of the plurality of refrigerators and operated, only the compressor is turned on and off with the valves in the refrigerator open, thereby preventing noise from the opening and closing of the valve. Since the occurrence frequency is minimized, the operation noise of the kimchi storage as a whole is reduced.
