Title:
METHOD AND DEVICE FOR CONTROLLING DRAINAGE PUMP, APPARATUS AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/068546
Kind Code:
A1
Abstract:
Provided in the present application are a method and device for controlling a drainage pump, an apparatus and a storage medium. The method comprises: acquiring electric motor operating parameters of an electric motor of a drainage pump during an operating process; determining a water amount interval of the current amount of water in a drainage pipe connected to the drainage pump according to the electric motor operating parameters; and determining the current rotating speed of the electric motor according to a preset rotating speed corresponding to the water amount interval. The present application performs variable frequency control on the electric motor according to the actual situation of the amount of water in the drainage pipe, so as to make the rotating speed of the electric motor always match the amount of water in the drainage pipe, thereby solving the problems of noise and motor heating caused by the use of high-rotating-speed drainage when the amount of water is small, favorably prolonging the service life of the electric motor, and improving the drainage efficiency. In addition, drainage starts only when the amount of water in the drainage pipe is determined to be greater than a preset amount of water, thereby solving the problems of a rising motor temperature, noise, etc. caused by drainage under conditions where the amount of water is small. Same can avoid the situation where one-way blockage of the drainage pump is misjudged as the amount of water being greater than the preset amount of water, thereby improving the accuracy of water amount detection.
