Cleaner

Abstract

A cleaner according to the present invention includes a cleaner main body, and a suction unit connected to the cleaner main body to suck air containing dust, and provided with a brush assembly brought into contact with a floor, wherein the brush assembly includes a rotating rod rotatable in one direction, a brush portion protruding from an outer circumferential surface of the rotating rod to rotate together with the rotating rod, and a blade erected at the rear of the brush portion in the one direction to be adjacent to the brush portion, and brought into contact with the brush portion during the rotation in the one direction, to prevent foreign substances from getting tangled in the brush portion. This configuration may prevent foreign substances such as hair and the like from being tangled in the brush portion during an operation of the cleaner.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]Pursuant to 35 USC § 119 (a), this application claims the benefit of an earlier filing date and priority to Korean Application No. 10-2016-0184449, filed on Dec. 30, 2016, the contents of which are incorporated by reference herein in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to a cleaner for removing dust on a floor by using a suction flow.BACKGROUND OF THE INVENTION[0003]Generally, a cleaner includes a vacuum cleaner in which a fan is rotated by a driving motor to generate a suction flow so as to suck dust. In recent years, as an application field of robots has expanded, a robot cleaner has been produced which is configured to autonomously travel within a predetermined space to suck dust on a floor or mop the floor.[0004]A cleaner which is operated by a user's manipulation or autonomously travels is provided with a brush assembly for effectively sucking dust on a floor (surface). Specifically, the brush assemb...

AI Technical Summary

Benefits of technology

The present invention provides a cleaner with a brush assembly that prevents foreign substances (such as hair) from getting inside the brush and becoming a permanent part of it. The brush can be easily made in different shapes and dense arrangements. The components of the brush assembly can also be easily assembled with each other.

Problems solved by technology

Particularly, a case where hair or the like gets tangled between the bristles constituting the brush becomes a major problem.

That is, there has been a limit in preventing or limiting hair from getting tangled during the operation of the cleaner.

In addition, there are various difficulties in a process of fabricating a brush assembly having a rotating body which includes a brush and a blade.

Typically, as disclosed in Patent Document 1, there is a problem that a method of directly planting a large number of bristles in a circular rotating body requires a long fabricating time and lots of fabricating costs.

In addition, there is a limit in densely constructing a space between bristles, which is likely to deteriorate cleaning performance.
