LAUNDRY TREATMENT DEVICE

WIPO Patent Application WO/2022/237430

A1

Disclosed in the present invention is a laundry treatment device. The laundry treatment device comprises a drum, wherein an end cover is arranged at the center of the drum bottom of the drum, and a cavity is jointly enclosed by the end cover and the drum bottom of the drum; the cavity is provided with a pipeline therein, and a ventilation channel in communication with the inside and outside the drum is formed inside the pipeline; and a space between the exterior of the pipeline and the interior of the cavity forms a water intake channel for introducing external water into the drum. By means of the arrangement of the pipeline in the cavity, the pipeline divides the interior of the cavity into the water intake channel and the ventilation channel, such that the ventilation channel is arranged close to the water intake channel, and thus, the air pressure at the water intake channel is consistent with that at the exterior of the drum, thereby avoiding the occurrence of the phenomenon in which the flow of inflow water is affected due to the pressure at a water inlet of a non-porous drum being overly large or overly small.
