Title:
AUTONOMOUS ELECTRICAL CLEANING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/225852
Kind Code:
A1
Abstract:
Proposed is an autonomous electrical cleaning apparatus with which it is possible to efficiently clean, and in which the strength of suction negative pressure, the speed of a rotating brush, the speed of a drive wheel, etc., can be appropriately set in accordance with the type of surface to be cleaned. The present invention is provided with: an electric blower 13 that generates suction negative pressure in a suction opening 11; a rotating sweeping body 15 disposed in the suction opening 11; a rotating sweeping body drive unit 16 that drives the rotating sweeping body 15; a drive wheel 17 that supports a cleaner main body 12; a drive wheel drive unit 18 that drives the drive wheel 17; a surface-to-be-cleaned sensing unit 27 that senses the type of a surface to be cleaned; and a robot control unit 19 that changes a controlled variable for any of the suction negative pressure, the speed of the rotating sweeping body 15, the rotation direction of the rotating sweeping body 15, and the speed of the drive wheel 17, on the basis of the type of the surface to be cleaned. The surface-to-be-cleaned sensing unit 27 senses the type of the surface to be cleaned at a sensing position forward from the element for which the controlled variable is to be changed, and the robot control unit 19 changes the controlled variable when the element for which the controlled variable is to be changed has reached the sensing position of the surface-to-be-cleaned sensing unit 27.
