Drainage pump control method, device and equipment and storage medium

Abstract

The invention provides a drainage pump control method, a device and equipment and a storage medium. The method comprises the steps that controlling a motor of a drainage pump to rotate by a first preset duration in the first direction; collecting motor operation parameters within a first preset time length; determining whether the water quantity in a drainage pipe is greater than a preset water quantity or not according to the motor operation parameters; and controlling the motor to drive the drainage pump to start draining according to the water volume greater than the preset water volume. Before drainage, whether the water amount in the current drainage pipe is larger than the preset water amount or not is judged according to the motor operation parameters. And only when the water amountis determined to be greater than the preset water amount, drainage is started, and the problems of motor temperature rise or noise caused by drainage under the condition of small water amount are avoided. And the water volume condition when the motor operates in different directions is detected, so that the situation that the one-way blockage of the drainage pump is misjudged that the water volume is greater than the preset water volume is effectively avoided, and the water volume detection accuracy is improved. The problem that the motor is heated and even damaged due to false starting underthe one-way blocking condition is avoided, and noise in the drainage process is lowered.

Description

Technical field[0001]This application belongs to the technical field of electrical equipment, and specifically relates to a drainage pump control method, device, equipment and storage medium.Background technique[0002]Drain pumps are installed in household appliances such as washing machines, air conditioners, and dishwashers. When the household appliances are running the drain program, the main control board controls the motor of the drain pump to run at a constant speed for draining. After draining is completed, the motor is controlled to stop.[0003]However, the above-mentioned drainage process controls the motor to run at a constant speed under any circumstances. When the amount of water in the drain pipe is small, the motor still runs at a relatively high constant speed, which will cause the motor to heat up, the drain pump will produce a lot of noise, and cause waste of resources.Summary of the invention[0004]This application proposes a drainage pump control method, device, equi...
