Benefits of technology
The present patent proposes a control method for a refrigerator that can solve the problem of a refrigerator not being able to cool normally due to a connection error between the capillary tube and a solenoid valve during production. This method involves acquiring the compartment that is currently requesting cooling, detecting if it is not cooled after a set time, identifying the currently cooled compartment, and interchanging the valve body rotation angles of the currently requesting cooling compartment and the currently cooled compartment. This results in the currently requesting cooling compartment being cooled, reducing the repair rate, improving production efficiency, and lowering fabrication costs.
Problems solved by technology
However, because the label falls off during the transportation or the operation of workers is not careful and like circumstances, error connections between the outlet tube of the solenoid valve and the capillary tube may still occur such that the refrigerator cannot be cooled normally, and the refrigerator can only be found abnormally operating and repaired after being subjected to commercial inspections, causing the production efficiency of the refrigerator to be low and fabrication costs to be high.

A control method and device for a refrigerator, and the refrigerator. The refrigerator comprises at least two compartments. The control method comprises: acquiring a compartment currently requesting cooling; after detecting and confirming a first set time, the compartment currently requesting cooling not being cooled, determining a currently cooled compartment, and interchanging currently set valve body rotation angles corresponding to the compartment currently requesting cooling and the currently cooled compartment requesting cooling. The present disclosure may solve the problem in which a refrigerator cannot be cooled normally due to a connection error between the capillary tube and a solenoid valve during the production of a multi-system refrigerator, and reduces the refrigerator repair rate, improves the refrigerator production efficiency, and reduces fabrication costs.
Description
CROSS-REFERENCE TO RELATED PRESENT APPLICATIONS[0001]The present application claims the priority of a Chinese Patent Application No. PCT / CN2018 / 124968 entitled “Control Method and Device for Refrigerator, and Refrigerator” filed on Dec. 28, 2018 by Hefei Midea Refrigerator Co., Ltd., Hefei Hualing Co., Ltd., and Midea Group Co., Ltd.BACKGROUNDTechnical Field[0002]The present disclosure relates to the technical field of electrical appliances, in particular to a control method and device for a refrigerator, and the refrigerator.Description of the Related Art[0003]With the development of economy and technology and the upgrading of consumer demands of a wide range of customers, refrigerators are developing towards large volume and multi-function. As the basic technology of refrigerators, refrigerating systems have also developed from single systems to multiple systems. Multi-system refrigerators are featured with multiple capillary tubes and one solenoid valve with “one-in-multiple-out”...
