Document Type and Number:
WIPO Patent Application WO/2023/221863
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a base assembly and a clothes treatment device. The base assembly comprises a base and a dust collection assembly. The base is provided with an accommodating space for accommodating a robot cleaner, and the accommodating space is provided with a dust collection port and an air return port. The dust collection assembly comprises a dust collector, a dust collection pipe and an air return pipe, wherein the dust collection pipe communicates the dust collection port with an air inlet of the dust collector, the air return pipe communicates an air outlet of the dust collector with an air return port, and the dust collection pipe is shorter than the air return pipe. According to the base assembly in the embodiments of the present application, impurities in a dust storage space of the robot cleaner are suctioned into the dust collector under the action of negative pressure, and air can circularly flow between the dust storage space and the dust collection assembly, such that the air intake of the assembly can be increased, and dust can be discharged more thoroughly; the air return pipe is longer, the dust collection pipe is shorter, and the dust collection pipe has a shorter airflow path, such that the probability of dust staying in the dust collection pipe can be reduced; and a filtered airflow mainly passes through the air return pipe, such that the problems of impurities blocking the pipe and staying in the pipe do not exist.
