Patent number: 10264938Abstract: A vacuum cleaner includes a main casing, driving wheels, side brushes, an obstacle sensor, and a controller. The driving wheels enable the main casing to travel. The side brushes are reciprocatively movable in both a direction of protruding from an outer frame of the main casing and its opposite direction, enabling cleaning of dust and dirt located outside the outer frame of the main casing. The obstacle sensor detects an obstacle by detecting a movement of the side brush in the opposite direction due to its contact with the obstacle. The controller controls drive of the driving wheels based on detection of an obstacle by the obstacle sensor to make the main casing autonomously travel. The vacuum cleaner can detect an obstacle at a position of a side brush while securely cleaning dust and dirt located outside an outer frame of a main casing by the side brush.Type: GrantFiled: April 22, 2015Date of Patent: April 23, 2019Assignee: TOSHIBA LIFESTYLE PRODUCTS & SERVICES CORPORATIONInventors: Hiromitsu Ichikawa, Masatoshi Tanaka, Hiromitsu Murata, Atsushi Morishita, Yukio Machida

Patent number: 10201261Abstract: A vacuum cleaner includes link mechanisms that connect a bumper to be movable in a relatively horizontal direction with respect to a case main body. A coil spring energizes the bumper in a direction separated from the case main body. Obstacle sensors are arranged at positions facing the bumper in the case main body, and detect an obstacle by detecting movement of the bumper, due to contact with the obstacle, in at least one of a direction opposite to an energizing direction of the coil spring and a direction crossing such a direction. A controller controls the drive of a driving wheel based on detection of the obstacle by the obstacle sensor to allow the main body case to travel autonomously. The vacuum cleaner can detect an obstacle brought into contact with the bumper in a wide range with a simple configuration.Type: GrantFiled: April 22, 2015Date of Patent: February 12, 2019Assignee: TOSHIBA LIFESTYLE PRODUCTS & SERVICES CORPORATIONInventors: Masatoshi Tanaka, Atsushi Morishita, Hiromitsu Ichikawa, Hiromitsu Murata, Yukio Machida
