Problems solved by technology
However, when the drainage pump is blocked, the motor is still controlled to run at a high constant speed, which will cause the motor to heat up, the drainage pump will generate a lot of noise, and the drainage efficiency is very low, resulting in waste of resources

The invention provides a drainage pump control method and device, equipment and a storage medium. The method comprises the steps that a motor of a drainage pump is controlled to change the rotation direction every first preset duration; motor operation parameters in the rotating process of the motor are collected in real time; determining whether the drainage pump is blocked in the first direction or not according to the current motor operation parameters; controlling the motor to rotate according to a second direction opposite to the first direction when the drainage pump is blocked in the first direction. The motor is controlled to periodically change the rotation direction, and the one-way blocking condition of the drainage pump can be effectively reduced. And when blockage is determined, the motor is controlled to be switched to reverse operation, so that higher drainage efficiency can be ensured, the temperature of the motor is not increased, the drainage pump is prevented from generating great noise, and resource waste under the condition that the drainage pump is blocked in one direction is reduced. And the drainage pump operates in the reverse direction under the one-way blockage condition, sundries wound on the impeller of the drainage pump can be removed, and the one-way blockage condition of the drainage pump can be dredged.
Description
technical field [0001] The 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] Washing machines, air conditioners, dishwashers and other household appliances are provided with a drain pump and its corresponding motor. The motor shaft included in the motor is connected to the impeller of the drain pump, and the impeller is driven by the motor to rotate to drain water. The rotation direction of the motor is consistent with the rotation direction of the impeller of the drainage pump. By changing the three-phase control parameters of the motor U, V and W, the motor can be controlled to change the rotation direction, thereby driving the impeller of the drainage pump to change the rotation direction. Regardless of whether the impeller of the drainage pump rotates forwardly or reversely, the suction force formed by it can discharge the wate...
