Problems solved by technology

[0006] However, according to the self-propelled sweeper in the above-mentioned conventional example, it can be seen that the side brushes are often rotated during sweeping, so there is a problem that this share of power is consumed and the noise becomes louder.
In addition, the side brushes are effective for collecting garbage at places close to walls or around obstacles, etc., where the main dust collection mechanism is difficult to collect dust. However, when driving in places with few obstacles, such as the center of a room, there are garbage The risk of being scattered, and the possibility of being caught on power supply ropes, etc. also increases

Embodiment Construction

[0032] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0033] figure 1 A perspective view showing the cleaning machine 100 in the embodiment, figure 2 A bottom view of the sweeper is shown.

[0034] refer to figure 1 , where 1 is a buffer, 2 is an obstacle detection sensor, 3 is a box for dust collection, and 4 is a fan motor for dust collection.

[0035] The bumper 1 also serves as a contact sensor such as a switch for detecting when an obstacle or the like suddenly contacts the sweeper 100 . The shock absorber 1 functions as a sensor for stopping the sweeper 100 and performing a reverse operation, for example, when it touches a foot of a person who suddenly ran out.

[0036] The obstacle detection sensor 2 is a non-contact sensor such as an ultrasonic sensor for detecting an obstacle, and is provided with an array having a signal transmitter and a signal receiver as a pair on the side of the main body of the sweeper ...

Abstract

Only when a wall side and the vicinity of an obstacle are cleaned, a side brush is operated and the cleaning is carried out, and when any other place than the wall side and the vicinity of the obstacle is cleaned, the side brush is maintained in a stoppage state. When a place such as the wall side or the vicinity of the obstacle in which dust is easy to accumulate is cleaned, the side brush is operated to enhance the dust collecting property. When any other place than the wall side or the vicinity of the obstacle is cleaned, the side brush is stopped to suppress power consumption and generation of a noise. A judgment processing portion detects based on a detection signal from an obstacle detecting portion that a cleaner is approaching a wall or an obstacle. In response to such detection, the judgment processing portion instructs a travel steering portion to carry out immediate rotation and change of a travel direction, or travel along a wall side. Also, the judgment processing portion instructs a side brush driving portion to drive a side brush only in the rotation and in the wall side travel, and to stop the side brush in straight advance travel.

Description

technical field [0001] The present invention relates to a sweeper, and is particularly suitable for a self-propelled sweeper having an auxiliary dust-collecting mechanism such as a side brush in addition to dust-collecting mechanisms such as a dust-collecting port or a suction nozzle. Background technique [0002] In recent years, self-propelled sweepers of the so-called independent induction type equipped with microcomputers and various sensors have been developed and are becoming popular day by day. [0003] This self-propelled sweeper is usually equipped with a dust collection mechanism such as a suction nozzle or a brush at the bottom of the main body. When running autonomously by independent sensing, the wheel speed and the driving position in the forward direction are determined at each time. In addition, a forward obstacle in the forward direction is detected by a contact-type or non-contact-type sensing mechanism, so that the obstacle can be avoided and the advancin...
