Description

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

The present invention relates to a method of controlling the operation of kimchi storage, and more particularly, the method of refrigeration of kimchi storage that can prevent the temperature of fermented food is lowered to low temperature because the fermented food is not immediately taken out from the kimchi storage after fermentation is completed. It is about.

In general, in order to store frozen foods, refrigerated foods and fermented foods (for example, kimchi, etc.), they should be stored at a temperature suitable for storing them, and a refrigerator having a freezer and a refrigerating chamber is mainly used to perform these functions. Was 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, as shown in Figure 1, the kimchi storage room to be described later to be stored largely kimchi is formed therein, and the kimchi on the upper side of the main body 10 The door 20 is hinged to be rotatable to open and close the storage compartment.

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 the predetermined portion of the upper surface of the door 20, operation conditions (operation modes such as ripening mode and refrigerated storage mode, kimchi type and ripening degree and ripening speed during ripening mode, etc.) can be freely selected according to the user's preference The key input unit 60 is attached to the door 20, and the door handle 70 is installed on the front of the door 20 so that the user can easily grab and open the door 20.

Here, as shown in FIG. 2, a compressor 12 is installed at a lower portion of the main body 10 to compress the refrigerant at high temperature and high pressure, and then circulate it, and inside one side wall of the main body 10. There is a temperature sensor 14 for sensing the temperature in the refrigerator, a heater 17 for generating heat to raise the internal temperature of the refrigerator, and an evaporator for cooling the internal temperature of the refrigerator by generating cold air. 18) are installed respectively.

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

First, the user stores kimchi in the storehouse 10, and then operates the key input unit 60 to operate the operation conditions (operation modes such as ripening mode, refrigerated storage mode and fermentation mode, and types of kimchi in ripening mode). And the ripening degree and the ripening speed, the type of fermented food in the fermentation mode, etc.), a key signal corresponding to the selected operating condition is input to the control unit, not shown, which is inputted from the key input unit 60. The operation condition selected by the user is determined by the key signal, and the kimchi storage is operated according to the determined operation condition.

For example, in the refrigeration storage mode, the compressor 12 is driven by the control unit when the internal temperature of the refrigerator is higher than or equal to the preset compressor operating temperature, and the refrigerant 12 is circulated from the evaporator 18 by the circulation of the refrigerant according to the driving of the compressor 12. The cold air is generated and the internal temperature of the main body 10 is lowered by the cold air generated from the evaporator 18, and the driving of the compressor 12 is stopped by the controller when the internal temperature is lower than the preset compressor stop temperature. The temperature inside the refrigerator is maintained at a preset refrigerated storage temperature (for example, about -1 ± 2 ° C.) to store the kimchi stored in the refrigerator.

In the aging mode, when the internal temperature is lower than the predetermined heater driving temperature, the heater 17 is driven by the control unit, and the internal temperature of the main body 10 is raised by the heat generated from the heater 17, thereby increasing the internal temperature of the internal chamber. If the temperature is equal to or higher than the predetermined heater driving stop temperature, the driving of the heater 17 is stopped by the control unit, so that the high internal temperature is at a predetermined ripening temperature (for example, about 23 ± 2 ° C. during fast ripening, and usually during ripening). Kimchi stored in the inside of the oven is aged.

In addition, in the fermentation mode, as can be seen with reference to Figure 3, the high internal temperature is less than the heater driving temperature (Tmin; for example, about 41 ℃ when the fermented food is Sikhye) according to the type of fermented food selected by the user When the heater 17 is driven and the internal temperature of the main body 10 is increased by the heat generated from the heater 17, the internal temperature of the heater 10 is the heater operation stop temperature Tmax according to the type of fermented food selected by the user. For example, when the fermented food is about 45 ° C.), the driving of the heater 17 is stopped, so that the high internal temperature is a fermentation temperature (ΔT) according to the type of fermented food selected by the user. In case of fermented foods, fermented foods are kept at 43 ± 2 ℃).

However, in the fermentation mode as described above, when the set fermentation time (ts) is exceeded and the fermentation operation is terminated, the temperature of the fermented food stored in the refrigerator is naturally lowered as the driving of the heater is stopped. After the fermentation process is completed, re-heating is performed again before the food temperature is lowered, so that the cooking is completed. Therefore, the user does not quickly remove the fermented food from the inside of the food. There is a problem that the fermented food is not cooked optimally when lowered.

For example, when cooking Sikhye, a suitable amount of water, rice, malt, and other ingredients are put in a kimchi cell to ferment for a predetermined fermentation time, and then the fermented Sikhye raw material is heated before the temperature becomes lower. For example, if you boil it to the boiling point of water using a gas stove, etc., Sikhye is completed.If fermentation is completed and the user leaves it without leaving the sikye raw material, the temperature of sikhye raw material naturally decreases and the unique taste of Sikhye lives. There was no issue.

Therefore, the present invention has been made in order to solve the problems of the prior art as described above, by keeping the temperature of the fermented food at a predetermined temperature after the fermentation operation is completed, the user can immediately fermented food from the kimchi storage The object of the present invention is to provide a method of controlling the operation of kimchi storage, which can prevent the temperature of fermented foods from dropping even if it is not taken out.

As can be seen from the drawings, the hardware for carrying out the present invention includes a key input unit 100, a temperature sensing unit 110, and a controller. And a compressor driving unit 130, a compressor driving unit 130, a compressor driving unit 130, a heater driving unit 140, a heater 17, a display unit 150, and an alarm sound generating unit 160. Since the basic configuration is the same as the kimchi storage shown in Figures 1 and 2 will be given the same reference numerals for the same components and duplicate description will be omitted.

In FIG. 4, the key input unit 100 includes a plurality of selection buttons for selecting and inputting operating conditions (for example, an operation mode such as a refrigerated storage mode, a aging mode, a fermentation mode, and a kind of fermented food). When the user operates the selection button and outputs the corresponding key signal to the control unit 120.

The temperature detecting unit 110 detects the internal temperature of the main body 10 and outputs a temperature signal corresponding to the detected internal temperature to the control unit 120.

The controller 120 outputs a control signal for selectively driving the compressor 12 or the heater 17 according to an operating condition set by the user through the key input unit 100.

The compressor driver 130 is driven by applying power to the compressor 12 by a control signal from the controller 120, the heater driver 140 is a heater 17 by the control signal from the controller 120 Power is applied to drive.

The display unit 150 turns on a display lamp corresponding to each selection button of the key input unit 100, and displays each operation state of the kimchi storage by a control signal from the control unit 120.

The alarm sound generating unit 160 outputs a corresponding operation sound when each selection button of the key input unit 100 is operated, and corresponds to each operation state of the kimchi storage by a control signal from the control unit 120. Outputs an alarm sound.

An operation example of the present invention through the hardware configured as described above will be described in detail with reference to FIGS. 4 to 6.

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), each component of the kimchi storage including the control unit 120 is initialized, and the body 10 from the temperature sensing unit 110 is initialized. The temperature signal corresponding to the internal temperature of the) is input to the control unit 120 (S10).

At this time, the user operates the selection button of the key input unit 100 to operate the operation conditions (operation mode such as ripening mode, refrigerated storage mode and fermentation mode, kimchi type, ripening degree and ripening speed in ripening mode, and fermentation mode. Type of fermented food, etc.), a key signal corresponding to the operation condition selected by the user is applied from the key input unit 100 to the controller 120.

Herein, the controller 120 determines whether the operation mode selected by the user is the "fermentation mode" through the key signal applied from the key input unit 100 (S20), and the determination result is the "fermentation mode". If not, perform another operation mode selected by the user (for example, refrigerated storage mode or ripening mode).

If the operation mode selected by the user is the “fermentation mode” as a result of the determination in step S20, the controller 120 determines the fermentation temperature according to the type of fermented food selected by the user through the key input unit 100. ΔT ₀ ; for example, 43 ± 2 ° C. when fermenting Sikhye and maturation time (ts; for example, about 6 hours when fermenting Sikhye) is set (S30).

Then, the control unit 120 drives the heater 17 according to the fermentation temperature (ΔT ₀ ) set in the step (S30) to perform the fermentation operation (S40).

That is, in step S40, the controller 120 senses the temperature inside the body 10 by the temperature signal from the temperature sensing unit 110, and the detected temperature inside is set in step S30. If the heater driving temperature (Tmin ₀ ) determined according to the fermentation temperature (ΔT ₀ ) or less, the heater driving signal for driving the heater 17 is output to the heater driving unit 140.

Power is applied from the heater driving unit 140 to the heater 17 by the heater driving signal from the control unit 120 to generate heat from the heater 17, and the body 10 by the heat generated from the heater 17. The internal temperature of) rises.

When the internal temperature of the high by the driving of the heater 17 is raised to the heater driving stop temperature (Tmax ₀ ) determined according to the fermentation temperature (ΔT ₀ ) set in the step (S30), the control unit 120 of the heater 17 A heater driving stop signal for stopping driving is output to the heater driving unit 140.

The supply of power applied from the heater driving unit 140 to the heater 17 is stopped by the heater driving stop signal from the control unit 120 to stop the heat generation from the heater 17.

As described above, the controller 120 drives the heater 17 according to the internal temperature and the fermentation temperature ΔT ₀ set in the step S30 to perform the fermentation operation, and counts the time by driving the built-in timer ( S50), it is determined whether the counted time has passed the fermentation time ts set in the step S30 (S60), and as a result of the determination, the counted time is less than the fermentation time ts set in the step S30. After that, the process returns to the step S40 to continue the fermentation operation.

If, as a result of the determination in step S60, the time counted up to the present has passed the fermentation time ts set in the step S30, the controller 120 stops the fermentation operation and displays a display indicating that fermentation is completed. The signal and the alarm sound output signal are output to the display unit 150 and the alarm sound generator 160 (S70).

The display signal from the controller 120 indicates that fermentation is completed on the display unit 150, and the alarm sound generator 160 generates an alarm sound by the alarm sound output signal from the controller 120. .

Then, the control unit 120 switches the operation mode to the temperature maintenance mode (S80), and sets the temperature according to the type of fermented food selected by the user (ΔT ₁ ; for example, when fermenting Sikhye, about 30 ± 2 ° C.) In accordance with the driving of the heater 17 to perform a temperature maintenance operation (S90).

In the step S90, the control unit 120 detects the internal temperature of the main body 10 by the temperature signal from the temperature sensing unit 110, so that the detected internal temperature is in accordance with the set temperature ΔT ₁ . If it is less than the determined heater driving temperature (Tmin ₁ ), the heater driving signal for driving the heater 17 is output to the heater driving unit 140.

Power is applied from the heater driving unit 140 to the heater 17 by the heater driving signal from the control unit 120 to generate heat from the heater 17, and the body 10 by the heat generated from the heater 17. The internal temperature of) rises.

When the internal temperature of the refrigerator is increased to the heater driving stop temperature Tmax ₁ determined by the set temperature ΔT ₁ by the driving of the heater 17, the control unit 120 stops driving of the heater 17. The driving stop signal is output to the heater driver 140.

The supply of power applied from the heater driving unit 140 to the heater 17 is stopped by the heater driving stop signal from the control unit 120 to stop the heat generation from the heater 17.

As described above, the controller 120 drives the heater 17 according to the set temperature ΔT ₁ to indicate that the fermentation is completed while performing the temperature maintenance operation, and to indicate that the operation mode has been switched to the temperature maintenance mode. The display signal is output to the display unit 150, and the alarm sound output signal for outputting the alarm sound is output to the alarm sound generator 160.

The display signal from the controller 120 indicates that the fermentation is completed and the current operation mode is the temperature maintenance mode, and the alarm is generated by the alarm sound signal from the controller 120. An alarm sound is generated from the sound generator 160.

On the other hand, if the power supply from the outside to the kimchi storage in each step described above is stopped driving the kimchi storage and the control operation of the control unit 120 is terminated.

That is, the present invention, as can be seen with reference to Figure 6, the fermentation operation according to the fermentation temperature (ΔT ₀ ) and the fermentation time (ΔT ₁ ) according to the type of fermented food selected by the user automatically when the fermentation operation is completed By switching to the temperature maintenance mode and maintaining the internal temperature at a predetermined temperature (ΔT ₁ ), the temperature of the fermented food is not lowered to a low temperature even if the user does not immediately take out the fermented food from the kimchi storage after the fermentation operation is finished. It is kept constant at a predetermined temperature.

As described above, according to the present invention, when the fermentation operation is finished, the operation mode is automatically switched to the temperature maintenance mode so that the temperature of the fermented food in the refrigerator is kept constant. Even if left unattended, there is an effect of preventing the temperature of the fermented food from falling to a low temperature.
