In FIG. 4, a plurality of buttons (for example, a flavor maintaining / vegetable storage button 31 and a ground soil button 32) can be selected and input to each course of the kimchi storage in the operation unit 30. , Kimchi selection button 33, the ripening degree selection button 34, the ripening speed selection button 35, the ripening select / cancel button (36)) is provided, the corresponding button when the corresponding button is operated by the user's operation The signal is output to the controller 100, and the temperature sensor 50 detects the internal temperature of the storage body 10 and outputs the signal to the controller 100.

The controller 100 generates a control signal for selectively driving the compressor 12 and the heater 17 according to the course selected and input through the operation unit 30 to drive the kimchi storage, and the heater 17 ), And after detecting a predetermined time (preferably, about 30 minutes) through the temperature sensor 50 to detect the internal temperature of the inside of the oven, and then set the ripening temperature (23 ± 2 ℃ in rapid ripening) In the case of aging, it is usually compared with 8 ± 2 ℃) or the set refrigerated storage temperature (about 0 ℃) to determine whether the heater 17 is broken and generate a control signal for displaying the same. Generates a control signal for stopping the driving of the heater 17 at the time of failure.

The compressor driver 120 drives the compressor 12 by the control signal from the controller 100, and the heater driver 170 drives the heater 17 by the control signal from the controller 100.

An operation process of the heater fixed detection method of the kimchi storage according to the present invention through the hardware configured as described above will be described in detail with reference to FIGS. 4 and 5.

First, increase the internal temperature in the kimchi storage in the ripening mode to maintain the internal temperature in the oven at the ripening temperature (about 23 ± 2 ℃ for fast ripening, usually about 8 ± 2 ℃ for quick ripening) or in the cold storage mode. In order to maintain the internal temperature in the refrigerator at a refrigerated storage temperature (about 0 ° C.), the controller 100 generates a control signal for driving the heater 17, and the heater driver ( The heater 17 is driven through 170 (step 510).

On the other hand, the control part 100 counts time while driving the heater 17 (step 512), and compares the counted time with a predetermined time (preferably about 30 minutes) (step 514).

If the time counted as a result of the comparison in step 514 does not exceed the predetermined time (about 30 minutes), the process returns to step 510 and the heater 17 is continuously driven, and the predetermined time is set. If (30 minutes) is exceeded, the control unit 100 detects the internal temperature of the interior of the refrigerator via the temperature sensor 50 (step 516), and detects the internal temperature and the ripening temperature of the interior of the refrigerator (at a time of rapid aging 23 ± 2). About 8 degrees Celsius, at the time of normal ripening, about 8 ± 2 ℃) or refrigerated storage temperature (about 0 ℃) is compared (step 518,520).

As a result of the comparison in the steps 518 and 520, if the internal temperature detected by the temperature sensor 50 is the ripening temperature range or the refrigerated storage temperature range, the controller 100 may display a normal state of the heater 17. While generating a control signal, the normal function is to raise the internal temperature in the ripening mode to maintain the internal temperature at the ripening temperature or to maintain the internal temperature in the refrigerated storage temperature at the refrigerating storage mode. Generate a signal.

Therefore, the normal state of the heater 17 is displayed through the display means (for example, at least one of the ripening degree display unit 37 or the storing display unit 38) by the control signal from the control unit 100 ( The heater 17 is driven through the step 522 and the heater driving unit 170, so that the internal temperature in the refrigerator is maintained at the aging temperature or the refrigerated storage temperature (step 524).

As a result of the comparison in the steps 518 and 520, if the internal temperature detected by the temperature sensor 50 is not the ripening temperature range or the refrigerated storage temperature, the control unit 100 detects a failure of the heater 17. A control signal for displaying is generated, while a control signal for stopping driving of the heater 17 is generated.

Therefore, the failure of the heater 17 is displayed by the control signal from the control part 100 via the display means (for example, at least one of the ripening degree display part 37 or the storing display part 38) (step) 526, the drive of the heater 17 is stopped via the heater driver 170 (step 528).

Therefore, according to the present invention, the presence or absence of the heater is displayed through the display means according to the internal temperature elevated by the heater after the predetermined time, and thus it is not only easy to know whether the heater is broken, but also at the time of failure of the heater. Since the driving of the heater is stopped, there is an effect that can prevent the malfunction of the kimchi storage in advance.
