Abstract

The present application proposes a drainage pump control method, device, equipment, and storage medium. The method includes: collecting motor operating parameters of the motor of the drainage pump during operation; The water volume interval to which the water volume belongs; the current rotational speed of the motor is determined according to the preset rotational speed corresponding to the water volume interval to which it belongs. This application realizes the frequency conversion control of the motor according to the actual situation of the water volume in the drainpipe, so that the motor speed is always compatible with the water volume in the drainpipe, and avoids the noise and motor heating problems caused by using a higher speed for drainage when the water volume is small. It is beneficial to prolong the service life of the motor and improve the drainage efficiency. And only when the water volume in the drainpipe is determined to be greater than the preset water volume, the drainage starts, so as to avoid problems such as motor heating or noise caused by drainage when the water volume is small. It can avoid the misjudgment that the water volume is greater than the preset water volume due to one-way blockage of the drainage pump, and improve the accuracy of water volume detection.

Description

technical field [0001] The application belongs to the technical field of electrical equipment, and in particular relates to a drainage pump control method, device, equipment and storage medium. Background technique [0002] Washing machines, air conditioners, dishwashers and other home appliances are all equipped with drain pumps. When the home appliances are running the drainage program, the main control board controls the motor of the drain pump to run at a constant speed to drain water. After the drainage is completed, the motor is controlled to stop. [0003] But above-mentioned drainage process all controls motor operation with constant rotating speed in any case. When the amount of water in the drain pipe is small, the motor still runs at a high constant speed, which will cause the motor to heat up, the drain pump will generate a lot of noise, and cause waste of resources. Contents of the invention [0004] This application proposes a drainage pump control method, d...
