Wide speed range motor control method applied to refrigerator

Abstract

The invention discloses a wide speed range motor control method applied to a refrigerator and relates to the technical field of refrigerator refrigeration and control. The control method comprises thesteps that firstly, after a refrigerator compressor is started, temperature situations of all chambers are monitored in real time through temperature sensors mounted in all the chambers of the refrigerator; secondly, after the monitored temperatures in all the chambers of the refrigerator are compared with set temperatures, the refrigeration demand grades of the chambers are judged; and thirdly,a wide speed range motor is driven to work according to a specific sped according to the actual refrigeration demand grades. According to the wide speed range motor control method, by reasonably adjusting the speed of the wide speed range motor, the problem of poor temperature stability of the chambers of the refrigerator is solved, and meanwhile, the refrigerator noise can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of refrigerator refrigeration and control, and in particular relates to a method for controlling a wide-speed motor applied to a refrigerator. Background technique [0002] With the continuous deepening of the concept of energy saving, emission reduction, low carbon and environmental protection and the continuous improvement of living standards, the market has higher and higher requirements for the use experience and overall quality of household refrigerators. The rotation speed of the ordinary motor remains unchanged during the working process, and the speed cannot be changed during the cooling process of the refrigerator compartment, which will cause poor temperature stability and comfort in the compartment. At the same time, the motor works at rated speed for a long time, and the whole machine is noisy. It will also remain high, which is not conducive to user experience. [0003] Therefore, in response t...
