Title:
CLEANING DEVICE AND AIR CONDITIONER INDOOR UNIT HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2019/120098
Kind Code:
A1
Abstract:
A cleaning device, comprising: at least one dust removing roller brush (100), a plurality of protrusions being formed thereon, and the roller brush being configured to contact a filter screen (600) of a wall-mounted air conditioner indoor unit and to push dust attached to the filter screen (600) to the outside of the filter screen (600) by means of the plurality of protrusions so as to remove the dust from the filter screen (600); an absorption roller brush (200), which is configured to contact at least part of an outer side surface of the filter screen (600) so as to absorb dust that is separated from the filter screen (600). The cleaning device loosens the dust absorbed by the filter screen by means of the dust removing roller brush (100) and at least partially separates dust from the mesh of the filter screen. Thus, the problem in the existing technology wherein part of the dust caused by cleaning a filter screen by means of a conventional manner of direct sweeping cannot be completely cleaned may be prevented.
