Title:
VACUUM CLEANER STATION, VACUUM CLEANER SYSTEM, AND METHOD FOR CONTROLLING VACUUM CLEANER STATION
Document Type and Number:
WIPO Patent Application WO/2021/177699
Kind Code:
A1
Abstract:
The present invention relates to a vacuum cleaner system comprising: a vacuum cleaner; a vacuum cleaner station; and a virtual plane including a virtual suction passage through-line, which passes through a suction passage in the longitudinal direction, and a virtual suction motor axis line, which extends the rotation axis of a suction motor. When the vacuum cleaner is coupled to the vacuum cleaner station, the plane positions the vacuum cleaner to penetrate at least a portion of the vacuum cleaner station and pass through a space in which the center of gravity of the vacuum cleaner can maintain the balance of the station, and thus the present invention has the effect that the vacuum cleaner and the station can be stably supported without falling over.
