Document Type and Number:
WIPO Patent Application WO/2023/171941
Kind Code:
A1
Abstract:
The present invention relates to a vacuum cleaner station comprising: a flow path switching module for selectively connecting a dust collection unit to a first vacuum cleaner flow path or a second vacuum cleaner flow path; and a control unit, which is arranged inside a housing and controls a dust collection motor and/or the flow path switching module, wherein the control unit operates the flow path switching module at least once before operating the dust collection motor so as to couple a connection hose to a corresponding vacuum cleaner flow path connection part to which a vacuum cleaner is coupled from among a first vacuum cleaner flow path connection part and a second vacuum cleaner flow path connection part, and thus a flow path can be automatically switched without requiring a user to manually switch a vacuum cleaner flow path and, further, dust is not scattered during flow path switching.
