Embodiment Construction
[0021] In this embodiment, the refrigerator compartment overcooling fault detection system includes a temperature sensor unit, a control unit and a display unit;
[0022] The temperature sensor unit is arranged in the refrigerator compartment for testing the temperature of the refrigerator compartment;
[0023] The control unit is used to collect the temperature of the refrigerator compartment measured by the temperature sensor in real time, and transmit a fault signal to the display unit; during specific implementation, the control unit can be integrated with the refrigerator controller.
[0024] The display unit is arranged on the outer surface of the refrigerator and is used for displaying fault signals. During specific implementation, the display unit is integrated with the display system of the refrigerator.
[0025] When the temperature limit value is set in the control unit, when the temperature of the refrigerator compartment collected by the control unit continues to...

The invention discloses a refrigerator chamber supercooling fault detection system and a refrigerator chamber supercooling fault detection method. The refrigerator chamber supercooling fault detection system is characterized by comprising a temperature sensor unit, a control unit and a display unit, wherein the temperature sensor unit is arranged in a refrigerator chamber and is used for detecting the temperature in the refrigerator chamber, the control unit is used for collecting the temperature, measured by a temperature sensor, of the refrigerator chamber in real time, and transmitting fault signals to the display unit, and the display unit is arranged on the outer surface of a refrigerator and is used for displaying the fault signals. The system and the method provided by the invention can be used for accurately detecting the supercooling fault of the refrigerator chamber, the method is simple, the users can be fast reminded when the supercooling fault occurs, and the problem of cold damage to food caused when the temperature of the refrigerator chamber is much lower than the designed temperature range is effectively avoided.
Description
technical field [0001] The invention relates to a detection system and a detection method for an overcooling fault in a refrigerator compartment. Background technique [0002] Overcooling of the refrigerator compartment means that the temperature of the refrigerator deviates from the design temperature range of the compartment, for example, the design range of the refrigerator compartment temperature is 2-8°C. During the use of the refrigerator, if the average temperature of the refrigerator is lower than 0°C, it can be considered that the refrigerator is too cold. Faults of overcooling in refrigerator compartments occur from time to time. Once a fault occurs, the user cannot find it immediately, which will cause food such as vegetables and fruits to be frozen. Generally, electric control refrigerators are equipped with temperature sensors in each room to control the temperature of the room. Multi-chamber direct-cooling refrigerators generally control the temperature by sw...
