Title:
METHOD AND APPARATUS FOR CONTROLLING DRAINAGE PUMP, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/089023
Kind Code:
A1
Abstract:
The present application provides a method and apparatus for controlling a drainage pump, a device, and a storage medium. The method comprises: at an interval of every first preset duration, controlling a motor of the drainage pump to change the rotation direction; collecting in real time motor operating parameters during the rotation of the motor; according to the current motor operating parameters, determining whether the drainage pump is blocked in a first direction; and according to the blockage of the drainage pump in the first direction, controlling the motor to rotate in a second direction, the second direction being reverse to the first direction. The present application controls the motor to periodically change the rotation direction, effectively reducing one-way blockage of the drainage pump. Moreover, when it is determined that a blockage occurs, the motor is controlled to rotate in the reverse direction, ensuring high drainage efficiency without heating up the motor, preventing the drainage pump from producing excessive noise, and reducing resource waste in the case of one-way blockage of the drainage pump. In addition, rotating in the reverse direction in the case of one-way blockage can remove debris wound on the impeller of the drainage pump, facilitating removal of the one-way blockage of the drainage pump.
