A self-correcting control method for electric valves of household refrigerators

Abstract

The invention discloses a household refrigerator electric valve self-correction control method. In the household refrigerator electric valve self-correction control method, an electric valve self-correction control system is composed of a control unit, an electric valve and a refrigeration unit. The control unit adjusts the refrigeration direction of the refrigeration unit through the electric valve. Temperature sensors are arranged in various chambers in a refrigerator to induct chamber temperature data information and transmit the data information to a computer board. The computer board judges the position of a valve element of the electric valve according to the chamber temperature information transmitted by the temperature sensors. The computer board records compressor start and stop data. According to the position of the valve element, the computer board controls the valve element to reset nearby according to the reset rule. The valve element nearby reset method is adopted in thehousehold refrigerator electric valve self-correction control method, deviation generated in the valve element work process is eliminated in time, deviation accumulation is avoided, and the problem that the electric valve is not switched in place is solved; and the reliability of the electric valve is effectively improved, the fault rate of the electric valve is reduced, the fault rate of the refrigerator is reduced, and the quality of the whole machine is improved.

Description

Technical field [0001] The invention belongs to the field of electric valve control of refrigerators, and particularly relates to a self-correcting control method for electric valves of household refrigerators. Background technique [0002] With the continuous improvement of people’s living standards, the quality requirements for household appliances are becoming higher and higher. However, the current multi-system refrigerators use electric valves due to impurities in the refrigeration system or software communication, which may cause electric There is a deviation in the rotation of the valve spool, and the accumulation of deviations for many times will cause the electric valve to switch incorrectly, cause the refrigeration turbulence of each compartment in the refrigerator, and even cause the refrigerator to not refrigerate; the purpose of the present invention is to at least solve the above technical defects, especially A self-correcting control method for electric valves of h...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a self-correction control method for the electric valve of a household refrigerator, by setting a computer board to control the electric valve core to reset according to the reset rule; to avoid the electric valve being affected by the signal interference problem of the software control process during the working process Switching deviation is caused to prevent the deviation from accumulating and eventually lead to inappropriate switching; by adopting the method of resetting the spool nearby, the deviation generated during the working process of the spool is eliminated in time, avoiding the accumulation of deviation, and eliminating the problem of insufficient switching of the electric valve; effectively improving the electric valve Valve reliability, reduce the failure rate of electric valves, reduce the failure rate of refrigerators, and improve the quality of the whole machine
