Water pump state detection method, circuit, device, storage medium, and program product

Abstract

The application relates to the technical field of water pump control, and provides a water pump state detection method, a circuit, equipment, a storage medium and a program product, which are applied to household electrical appliances, the household electrical appliances comprise a humidification water tank, a water pump is arranged in the humidification water tank, the water pump state detection method comprises the following steps: performing shutdown processing on the water pump in an operating state; collecting a reverse voltage of the water pump during the shutdown; determining the operating state of the water pump according to the amplitude characteristic of the reverse voltage; wherein the operating state comprises a normal state, an idle state or a locked-rotor state; and outputting a detection result of the water pump state according to the operating state. In the foregoing manner, the application judges whether the water tank is short of water or the water pump is locked by detecting the reverse voltage of the inertia of the water pump when the water pump is shut down, instead of the existing sensor mode, so that low-cost water pump state detection is realized.
