DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kimchi storage, and more particularly, to a kimchi storage in which a kimchi can be optimally refrigerated and stored by accurately detecting a temperature in the storage and driving a compressor. And to a drive control device and method.

[0002]

2. Description of the Related Art Generally, in order to store frozen foods and refrigerated foods or kimchi, they must be stored at temperatures suitable for storing them, respectively. And refrigerators equipped with refrigerators are mainly used.

On the other hand, when refrigerated food and kimchi are to be stored together in the refrigerator compartment of the refrigerator, the odor generated by the fermentation of the kimchi causes not only a bad smell in the refrigerator compartment but also other refrigerated food products. In addition, the smell of refrigerated foods is easily permeated, and the smell and smell of refrigerated foods is liable to be damaged. Therefore, it is necessary to store thick kimchi in another storage container due to an increase in refrigerated foods and kimchi stored in the refrigerator compartment.

[0004] Furthermore, in order to mature kimchi, the turtle containing kimchi is buried in the soil and kimchi is preserved in the soil to be matured properly to take advantage of its characteristics. Due to restrictions due to the living environment such as houses, it is difficult to store kimchi turtles in the dwellings rather than bury them in the ground.

[0005] Recently, in order to solve the above-mentioned problems, various studies have been made on kimchi storage for storing kimchi in a storage other than a refrigerator in various technical fields related thereto. The kimchi storage is typically as shown in FIG.

As can be seen from FIG. 1, the conventional conventional kimchi storage has a storage body (10) and a door (20) used for storing or removing the kimchi in the storage body (10). In order to set and perform the function of the kimchi storage, an operation section (30) provided with a plurality of keys and an interior (40) for storing the kimchi are provided.

The operation process of the refrigerated storage method of the kimchi storage constructed as described above will be described with reference to FIG. First, the user enters the storage (4)
After storing the kimchi in (0), after aging through the operation unit (30), if refrigerated storage is selected, the internal temperature of the refrigerator (40) during the set aging period is set at the aging temperature (preferably,
The kimchi is aged at approximately 25 ° C.

Next, the compressor motor is driven to circulate the refrigerant, and the air in the storage (40) is cooled by heat exchange with the air in the storage (40) through an evaporator installed in the storage main body (10). The internal temperature of the refrigerator (40) is kept at a set refrigerated storage temperature (preferably approximately 0 ° C.), and the aged kimchi is stored refrigerated.

On the other hand, FIG. 2 is a diagram for explaining the phase change of water. As can be seen from FIG. 2, the phase change of water at the temperature at which water freezes (0 ° C.) is shown. For a predetermined time (T)
During, the temperature is not changed.

[0010]

However, since the temperature sensor installed in the kimchi storage is fixed at a low temperature, an error occurs in the temperature sensed through the temperature sensor as time passes. As a result, there is a problem that the kimchi cannot be sufficiently aged or refrigerated because the internal temperature of the refrigerator cannot be accurately detected.

For example, as shown in FIG. 3, when the temperature sensor senses 0 ° C. (Ts 0 ° C.) lower than the actual 0 ° C. due to a defective temperature sensor, such a temperature difference (△ T1), the temperature inside the refrigerator sensed through the temperature sensor is sensed as a whole low, so that the kimchi cannot be matured or refrigerated.

Further, as shown in FIG. 4, when 0 ° C. (Ts 0 ° C.) sensed through the temperature sensor is higher than the actual 0 ° C. due to the failure of the temperature sensor, such a temperature difference
Since the temperature inside the refrigerator sensed through the temperature sensor is sensed as a whole by (△ T2), the kimchi cannot be sufficiently aged or stored in a refrigerator.

Accordingly, the present invention has been made to solve the above-mentioned problems of the kind, and an object of the present invention is to provide:
Kimchi storage that can optimally refrigerate and store kimchi stored in the refrigerator by accurately detecting the temperature inside the refrigerator using the temperature sensed when the phase of water changes, and driving the compressor accordingly. It is an object of the present invention to provide a drive control device and method.

And a compressor drive unit for driving the compressor according to a control signal from the unit.

[0015] In addition, the method for controlling the driving of the kimchi storage box includes a compressor driving step of driving the compressor in accordance with a temperature sensor value for sensing a temperature of water that changes in accordance with the temperature in the storage box; A temperature correction step of comparing the temperature sensing value of the sensor with the phase change temperature of water to correct an error in the temperature sensing value of the temperature sensor; and driving the compressor according to the temperature sensing value corrected by the temperature correcting step.
