Problems solved by technology

When the damper of the refrigerator fails to open or the electromagnetic valve fails to switch, it will cause some rooms to not be cooled; if the compressor fails or the refrigerant leaks, all rooms of the refrigerator will not be cooled.
During the use of the above-mentioned refrigerators, once the failure of the whole refrigerator or individual compartments fails to cool, the user cannot find out immediately, resulting in food deterioration

Abstract

The invention discloses a detection system for refrigeration incapability fault of a refrigerator. The detection system is characterized by comprising a first temperature sensor, a control unit and a display unit, wherein the first temperature sensor is arranged in a chamber to be detected and is used for detecting the temperature in the chamber to be detected, the control unit is used for collecting the temperature, measured by the first temperature sensor, of the chamber to be detected, and transmitting fault signals to the display unit, and the display unit is arranged at the outer surface of the refrigerator and is used for displaying the fault signals. The system provided by the invention can be used for judging the refrigeration incapability fault of each chamber of the refrigerator, users can be reminded in time, the method is simple, the efficiency is high, the food deterioration problem caused when the refrigeration incapability fault is not found in time is effectively avoided, and meanwhile, maintenance personnel can fast judge the fault reason according to the prompted fault information.

Description

technical field [0001] The invention relates to a detection system for non-refrigerating failure of a refrigerator. Background technique [0002] With the development of the refrigerator market, there are more and more large-volume multi-chamber electronically controlled refrigerators. Generally, each room of this type of refrigerator can be controlled independently, and the cooling control is realized through the switching of dampers or solenoid valves. When the damper of the refrigerator fails to open or the electromagnetic valve fails to switch, some compartments will not be refrigerated; if the compressor fails or the refrigerant leaks, all compartments of the refrigerator will not be refrigerated. During the use of the above-mentioned refrigerator, once the failure of the whole refrigerator or individual compartments fails to cool, the user cannot find out immediately, resulting in food deterioration. Contents of the invention [0003] In order to solve the shortcomi...
