Kind Code:
A1
Abstract:
Disclosed are a laundry treatment device, a drainage control method therefor, an apparatus and a storage medium. The method comprises: controlling a drainage pump of a laundry treatment device to operate in a first mode, wherein in the first mode, the drainage pump acts on the basis of a water level detection value of the water level in the laundry treatment device; and when a continuous operation duration corresponding to the drainage pump reaches or exceeds a set value, controlling the drainage pump to operate in a second mode, wherein in the second mode, the drainage pump cyclically operates at a first start-stop ratio, and the first start-stop ratio is the ratio of the operation duration to the stop duration in one cycle. In the embodiments of the present invention, the continuous operation duration of the drainage pump caused by water level detection failure may be effectively shortened, thereby reducing the operating noise of the drainage pump, and preventing heat and other damage caused by the drainage pump due to an excessively long continuous operation duration, which is advantageous in extending the service life of the drainage pump.
