Electric vacuum cleaner

Abstract

Provided is an electric vacuum cleaner in which a rag is wrapped around an electric brush built in an inhalation appliance for wiping and cleaning, which is advantageous for expanding the use of the electric vacuum cleaner. In order to wrap the rag (50) around the rotating brush (25), the rotating brush (25) can be rotated in a predetermined direction at a predetermined rotational speed by a brush motor (44). In addition, in order to remove the rag (50) wrapped around the rotating brush (25), the rotating brush (25) is repeatedly rotated forward / reversely. The suction force of the electric vacuum cleaner is strengthened so that the mop is automatically released by the suction force of the electric blower. According to the present invention, it is possible to provide an electric vacuum cleaner that can remove the rag (50) wrapped around the peripheral surface of the rotating brush (25) without touching it by the user, and is excellent in usability.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner, and more particularly to an electric vacuum cleaner in which a suction tool incorporating a rotating brush driven to rotate by a motor is used as a suction tool for sucking dust from a surface to be cleaned. Background technique [0002] A general electric vacuum cleaner has: an electric vacuum cleaner body that generates suction; and a suction device installed on the electric vacuum cleaner body through a hose or a conduit. Among them, the known structure of the suction device is to have a suction port opposite to the surface to be cleaned, and a rotating brush is built in the suction port. [0003] Objects such as hair or lint tend to get entangled with the rotating brush of the inhalation device during the cleaning operation. Patent Document 1 discloses a method for easily removing hair, lint, and the like entangled in a rotating brush. [0004] The method described in Patent Document 1 ...

Problems solved by technology

[0013] However, when the rotating brush is driven and rotated by a motor, although the rotating direction can be switched to one direction or another direction, in Patent Document 2, it is mentioned that the sticking on the rotating brush can be removed by switching the rotation of the rotating brush. hair or thread, etc., there is no hint in the literature

[0014] The structure described in Patent Document 3 is capable of wiping and cleaning with a wet cloth, but the structure described in Patent Document 3 has a problem that the size of the inhalation device increases because it has a dedicated roller for wrapping the wet cloth.

[0015] In addition, although the structure described in Patent Document 4 can perform wiping and cleaning with a mop, after the wiping and cleaning is completed, the dirty mop must be peeled off with fingers, so there is a problem of giving the user an unpleasant feeling.
