Abstract

The present application proposes a drainage pump control method, device, equipment and storage medium, the method comprising: controlling the motor of the drainage pump to rotate in a first direction for a first preset duration; collecting motor operating parameters within the first preset duration; According to the operating parameters of the motor, it is determined whether the water volume in the drainage pipe is greater than the preset water volume; according to the water volume being greater than the preset water volume, the motor is controlled to drive the drainage pump to start draining. The application judges whether the current water volume in the drain pipe is greater than the preset water volume according to the motor operating parameters before draining. Only when the water volume is determined to be greater than the preset water volume can the drainage be started, so as to avoid problems such as motor heating or noise caused by drainage when the water volume is small. It also detects the water volume when the motor runs in different directions, effectively avoiding the misjudgment that the water volume is greater than the preset water volume due to one-way blockage of the drainage pump, and improving the accuracy of water volume detection. Avoid the problem of motor heating or even damage caused by false start in the case of one-way blockage, and reduce the noise of the drainage process.

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] The present application proposes a drainage pump control me...
