Description

Refrigerator and its control method {REFRIGERATOR AND CONTROLLING METHOD THEREOF}

The present invention relates to a refrigerator and a control method thereof, and more particularly, to a refrigerator and a control method thereof capable of displaying a load of a refrigeration system and various sensors.

In general, a refrigerator is used to refrigerate and freeze food by a refrigeration system using a refrigerant, and the refrigeration system includes a compressor for refrigerant compression, a condenser for condensing the refrigerant from the compressor, and an evaporator for evaporating the refrigerant.

Among these refrigerators, a large-capacity SIDE BY SIDE type refrigerator has a refrigerator compartment and a freezer compartment left and right, and a refrigerator compartment evaporator and a freezer compartment evaporator are respectively installed in the rear regions of the refrigerator compartment and the freezer compartment to exchange heat with air in the refrigerator compartment and the freezer compartment. In addition, refrigerating chamber blowers and freezer compartment blowers are respectively provided in regions adjacent to each evaporator, and each blower fan circulates air in the refrigerating compartment and the freezing compartment to assist in heat exchange between the air inside and the evaporator.

On the other hand, for the smooth operation of the refrigeration system, the cooling fan for the cooling of the compressor is installed in the adjacent area of the compressor, the refrigerator compartment evaporator and the freezer compartment heater are respectively installed for eliminating defrosting. . In addition, the freezer compartment and the refrigerating compartment are equipped with a freezer compartment temperature sensor and a refrigerator compartment temperature sensor for sensing the refrigerator compartment temperature and the freezer compartment temperature. The detection values from the refrigerator compartment temperature sensor and the freezer compartment temperature sensor indicate whether or not the internal temperature is maintained at an appropriate level. It becomes a criterion for judgment and a driving criterion for the compressor and each blowing fan. In addition, a freezer compartment defrost sensor and a refrigerator compartment defrost sensor are installed in an area adjacent to the freezer compartment defrost heater and the refrigerator compartment defrost heater, and the detection value from each defrost sensor is a driving reference of each defrost heater.

The refrigerator is set to perform a self-diagnosis function to determine whether there is an abnormality of each sensor at initial startup, and when the self-diagnosis function is entered, all the LEDs of the operation panel are turned on. The controller determines whether there is an abnormality of each sensor according to the temperature value detected by each sensor, and displays the result on the corresponding LED of the operation panel.

For example, if the temperature detected by the left refrigerating chamber sensor installed on the left side of the refrigerating chamber is above + 50 ° C or below -50 ° C, the control unit judges that the sensor is in poor contact, the wire is open or short, the sensor is in itself defective, and the like. The LED's cold room 'weak' LED blinks and an alarm sounds. This failure indication is continued until the failure is eliminated or the self-diagnosis function is released.

However, since the conventional refrigerator performs a self-diagnosis function and displays the result, it is displayed on a predetermined LED at the time of design. Therefore, unless there is a separate manual showing the relationship between each load and the corresponding LED, the self-diagnosis is performed. It is not possible to grasp the subject or its performance. Therefore, the user can not grasp the normal operation at all, and the repairman is also not easy to grasp or repair.

In addition, during the operation of the refrigerator, it is impossible to know whether each sensor is operating normally. To perform the self-diagnosis function, it is cumbersome because the power of the refrigerator must be shut off and resupplyed. Blocking and resupplying causes a problem that the compressor goes unreasonably.

Accordingly, the above-mentioned problems can be solved by displaying the presence or absence of an abnormal load of each load of the refrigeration system through the display device of the present applicant.

It is therefore an object of the present invention to provide a refrigerator and a control method thereof, which are capable of displaying the presence or absence of an abnormality of each load of a refrigeration system using a display device.
