[0004] In this way, there is a passive adjustment method of forced reset, and it is impossible to detect the abnormal switching of the electric valve in time; it is impossible to reset and adjust in time when the abnormality occurs; often, the single-channel refrigeration system does not cool due to the abnormal switching of the electric valve, resulting in abnormal cooling of the refrigerator, and the temperature rises. The food stored in the refrigerator deteriorates, affecting user experience

The application provides an electric valve monitoring method and device for a refrigerator, and the refrigerator, which belong to the technical field of electric valve monitoring for refrigerators. The method includes: at the first moment when the electric valve is controlled to open the target refrigeration passage, obtaining the temperature of the refrigerator compartment corresponding to the target refrigeration passage, obtaining the first temperature, and obtaining the ambient temperature around the refrigerator; At a second time point after the first time point, obtain the temperature of the refrigerator compartment corresponding to the target refrigeration passage to obtain a second temperature; obtain a first temperature difference between the first temperature and the second temperature , and determine the temperature drop threshold of the target refrigeration passage under the ambient temperature; determine whether the switching of the electric valve is abnormal according to the magnitude of the first temperature difference and the temperature drop threshold. The embodiments of the present application can timely and accurately detect the abnormal switching of the electric valve of the refrigerator, realize reliable monitoring, effectively ensure the refrigeration performance of the refrigerator, and improve user experience.
Description
technical field [0001] The present application relates to the technical field of monitoring electric valves of refrigerators, in particular, to a method and device for monitoring electric valves of refrigerators, and a refrigerator. Background technique [0002] In recent years, the market demand of consumers for air-cooled refrigerators with multi-channel refrigeration systems is increasing. In order to realize the control of multi-channel refrigeration systems, more and more electric valve products that can control the on-off of refrigeration systems are used. [0003] At present, most of the multi-system air-cooled refrigerators using electric valves use the method of periodic reset of the electric valve (for example, the electric valve is forced to reset once every 300 minutes) to switch the on-off of each system. The method of regular reset is adopted to prevent the electric valve from being switched normally due to electromagnetic interference, signal interruption, imp...
