Description

Method for controlling room temperature in kimchi refrigerator

The present invention relates to a kimchi refrigerator for fermentation, aging, and storage, and more particularly, to a method for controlling the temperature inside a kimchi refrigerator, which can appropriately control the temperature in the refrigerator according to seasonal outdoor air temperature changes.

In many countries, rice-based countries tend to eat salted vegetables as a side dish, while meat-based countries tend to eat vinegared foods. In particular, in Korea, kimchi is a long-standing traditional food, which is mixed with vegetables such as cabbage or radish and seasoned with spices and flavors (for example, red pepper powder or salted fish) and fermented for several days at an appropriate temperature. I have eaten.

Kimchi refrigerator, which is widely known at present, is a device for fermenting and aging kimchi for the convenience of the user and storing it for a long time while maintaining the kimchi taste the same regardless of the season.

1 is a view showing a structure of a general kimchi refrigerator, the kimchi refrigerator has a door (100) opening and closing to accommodate the kimchi in the storage container 20 through any one side of the main body (10). The main body 10 is a cooling device for lowering the internal temperature of the storage container. The compressor 30 compresses the refrigerant into a high-temperature, high-pressure gas refrigerant, and coolant from the compressor 30 with ambient air. The condenser 40 for cooling through heat exchange of the evaporator and the evaporator pipe 60 for lowering the temperature of the storage container by making the refrigerant of the condenser 40 at a low temperature and low pressure. In addition, in the vicinity of the evaporator pipe 60, the in-vehicle temperature sensor 80 for detecting the in-vehicle temperature of the storage container 20 is attached.

Moreover, the heat insulating material 90 which surrounds the container and fills the inside of the main body 10 is provided around the storage container 20.

In addition, the heater 50 is installed in the main body 10 of the kimchi refrigerator as a heating device for increasing the internal temperature of the storage container 20.

In addition, the kimchi refrigerator has a function of controlling the kimchi refrigerator to be operated in a state set by the user by providing a microcomputer 70 in the main body 10. Furthermore, the microcomputer 70 controls the heating device or the cooling device by the temperature detected from the internal temperature sensor 80.

The conventional kimchi refrigerator configured as described above has a general cooling device and a heating device. When the user selects the system operation as fermentation or aging mode, the heating device is driven to ferment kimchi in a storage container, and then the cooling device is driven. By keeping the internal temperature of the storage container (eg, -2 ° C to 0 ° C in the case of kimchi ripening temperature), the taste and freshness of kimchi are preserved for a long time.

In this way, the kimchi refrigerator ferments, ripens or stores the kimchi in the storage container according to the set mode, and when the temperature detected by the internal temperature sensor 80 is out of the reference temperature range, the kimchi refrigerator is driven again to operate the heating device or the cooling device. It is kept constant.

However, in the high temperature control method of the kimchi refrigerator, since the air temperature around the kimchi refrigerator, that is, the outside temperature shows a big difference according to the season, the inside temperature of the refrigerator is changed during the opening and closing of the kimchi refrigerator.

This temperature change is particularly high when the temperature of the kimchi refrigerator is kept in the functional mode set during the summer, and the kimchi in the storage container is frozen during the winter season. The kimchi quickly became oxidized when maintained.

Accordingly, an object of the present invention is to control the inside temperature control of the kimchi refrigerator that can prevent the change of the kimchi taste by the change of the outside temperature by controlling the change in the temperature inside the high temperature for different seasons in order to solve the problems of the prior art as described above. To provide a method.

In order to achieve the above object, the present invention provides a method for controlling the temperature inside a kimchi refrigerator for fermenting, ripening and storing food, the method comprising: maintaining the temperature inside the kimchi refrigerator according to a set fermentation, ripening and storage mode, and a current date Comparing which season is included, adjusting the temperature control range of the kimchi refrigerator according to the season, and controlling the operation of the heating device and the cooling device according to the newly adjusted temperature range to change the seasonal outside air temperature. Accordingly, adjusting the temperature in the refrigerator.

In the manufacturing method of the present invention, the season is characterized by dividing into four quarters of spring, summer, autumn, winter to suit the climate of Korea.

In the manufacturing method of the present invention, the season is characterized by dividing by a predetermined quarter according to the average season temperature and precipitation for different countries' climate.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

2 is a flowchart showing an example of a method for controlling the temperature inside a kimchi refrigerator according to the present invention. Referring to this, the kimchi refrigerator according to the present invention has the same configuration as the kimchi refrigerator shown in FIG. It is to change the control range of the internal temperature according to the temperature change.

First, the microcomputer 70 of the kimchi refrigerator operates an internal system in a set operation mode (eg, fermentation and storage). That is, according to the set fermentation, fermentation, and storage mode, the Kimchi (or fermentation / storable food) contained in the storage container may be fermented and matured by operating a compressor, a cooling device, and a heater, to maintain the internal temperature of the Kimchi refrigerator. Save it. (See S10)

Next, the microcomputer 70 of the kimchi refrigerator according to the present invention compares the current date in which season, and after adjusting the temperature control range of the kimchi refrigerator according to the season, the heating to the newly adjusted temperature band By controlling the operation of the device and the cooling device, the internal temperature is adjusted according to the seasonal outdoor temperature change, thereby preventing deterioration of food stored in the interior due to the external temperature change.

For example, because the seasons of Korea are divided into four seasons, it is determined whether the current date is spring (approximately February 16 to June 20). If the current date is May 10, it is included in the spring, so the control temperature inside the refrigerator is set in the range of -2 ° C to 1 ° C, and the operation of the heater as the compressor and the heating device is controlled to the newly set temperature range. Keep it. (See S12 to S14)

If the current date is July 10, it is included in the summer (approximately June 21-August 31), so that the control temperature in the refrigerator is in the range of -3 ° C to 1 ° C. Operation is controlled to maintain the high temperature within the newly set temperature range. (See S16 to S18)

In addition, if the current date is September 15, it is included in autumn (about September 1 to October 31), so that the control temperature in the refrigerator is in the range of -2 ° C to 0 ° C. Operation is controlled to maintain the high temperature within the newly set temperature range. (See S20 to S22)

In addition, if the current date is December 25, it is included in winter (approximately November 1 to February 15), so the control temperature in the refrigerator is in the range of -1 ° C to 1 ° C. Control of the operation keeps the internal temperature in the newly set temperature range. (See S23-S24)

In the exemplary embodiment of the present invention, the seasonal change is divided into four quarters of spring, summer, autumn, and winter according to the climate of Korea, but in a hot or cold country, according to the average season temperature and precipitation according to the climate, the predetermined quarterly Set the season to divide.

As described above, the kimchi refrigerator of the present invention can prevent the deterioration of the food stored by the change of the outside temperature by controlling the change in the temperature inside the store by the season even if the ambient air temperature, that is, the outside temperature changes according to the season. It can keep fresh for a long time.
