Autonomous electric cleaner and electric cleaner

Abstract

An electric cleaner or an autonomous electric cleaner that prevents scattering of garbage and dust towards the back and both sides thereby enhancing cleaning rate (absorbing rate) is provided. In the autonomous electric cleaner 1 having an absorbing port 2b for absorbing garbage and dust arranged at the bottom surface of the main body 2 facing the floor or the cleaning surface, the back blade 11 and the side blades 12 that contact the floor and receive the garbage and dust without allowing them to pass are arranged at the back part and both the left and right sides, respectively, of the absorbing port 2b.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an autonomous electric cleaner and an electric cleaner that absorbs garbage and dust on a cleaning surface to clean the cleaning surface. [0003] 2. Description of the Related Art [0004] The electric cleaner that absorbs garbage and dust on the cleaning surface such as floor to clean the cleaning surface includes an autonomous type in which the cleaner autonomously travels by the drive of the motor, and a non-autonomous type in which the cleaner is pulled by a person and the like. In either electric cleaner, garbage and dust on the cleaning surface are absorbed along with external air from the absorbing port facing the cleaning surface by the suction force generated by an electric air blower made up of a motor and a fan, where the garbage and dust are then separated from the external air and captured and collected by a dust collecting body made up of a filter and the like, and the cle...

AI Technical Summary

Benefits of technology

[0018] Thus, the garbage and dust on the cleaning surface approach the absorbing port from the front not arranged with a blade, and scattering of the garbage and dust towards the back and both sides before being absorbed into the absorbing port is prevented by being received by the blades. Further, the garbage and dust remain in the vicinity of the absorbing port by the blades, so as to be swept and easily absorbed into the absorbing port by the rotating brush. The garbage and dust are collected towards the center of the absorbing port by the blades arranged on both sides of the absorbing port so as to be easily absorbed from the absorbing port. When the garbage and dust are received by the blade arranged at the back part of the absorbing port, the garbage and dust are less likely to move towards the sides along the blade, and variation in absorption of the garbage and dust depending on the position is suppressed since the distance to the absorbing port and the rotating brush is constant irrespective of the position of the garbage and dust on the receiving wall body. Further, when hard garbage such as a small rock hits the blade arranged at the back part of the absorbing port and bounces off, the garbage and the like hits the blades at the sides thereby being bounced towards the front at the center of the absorbing port, and thus the garbage and the like are easily absorbed from the absorbing port. Therefore, in the autonomous electric cleaner mostly used in a situation of not being monitored by a person, the remains of the garbage and dust unabsorbed from the absorbing port is reduced and thus the cleaning rate (absorbing rate) is enhanced. In addition, since the blades arranged at both sides of the absorbing port is slightly slanted from the perpendicular direction with respect to the blade arranged at the back of the absorbing port, it barely acts as the traveling resistance of the autonomous electric cleaner, and the air passes and escapes from a microscopic gap between the blades arranged at the back and both sides, and thus the air pressure on the inner side of the blade, that is, the space on the absorbing port side is adjusted, and the influence on the traveling performance of the autonomous electric cleaner is eliminated.

[0019] According to the present invention, the garbage and dust on the cleaning surface approach the absorbing port from the front that is open, and scattering towards the back and both sides before being absorbed into the absorbing port is prevented by being received at the receiving wall body, and thus the remains of the garbage and dust unabsorbed by the absorbing port is reduced and the cleaning rate (absorbing rate) is enhanced.

Problems solved by technology

In particular, in case of the autonomous electric cleaner that is mostly used in a situation of not monitored by a person, even if the garbage and dust are left unabsorbed while the cleaner is traveling on the cleaning surface, the operation of immediate returning back to where garbage and dust have been left unabsorbed is generally not performed, and thus the garbage and dust tend to remain on the cleaning surface.
