Benefits of technology

The patent text describes a vacuum cleaner with a suction head that reduces its operation force when moving forward, and that maintains its suction force when moving backward. This allows for improved performance and efficiency of the vacuum cleaner.

Problems solved by technology

However, since the brush base is covered by the cover and is thus not exposed to the outside, detection of the position of the brush base is not easy.
Further, when cleaning is performed while moving the suction head forward, operation of the suction head is not easy due to resistance of the surface to be cleaned.
That is, large operation force is required to move the suction head forward.

Abstract

A vacuum cleaner includes a suction head including a cover and a bottom plate provided with a suction hole through which air is sucked from a surface to be cleaned and rotatably combined with the cover. The bottom plate is rotated in one direction relative to the cover when the suction head moves forward, and is rotated in the other direction relative to the cover when the suction head moves backward. Further, the vacuum cleaner includes a brush base including brushes and movable upward and backward between the cover and the bottom plate. The brush base includes indicating parts exposed to the outside of the cover and forming at least a portion of the external appearance of the suction head.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Korean Patent Application No. 10-2012-0110306, filed on Oct. 4, 2012 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.BACKGROUND[0002]1. Field[0003]One or more embodiments relate to a vacuum cleaner which separates and collects dust from air sucked by suction force of a fan motor and has a suction head closely adhered to a surface to be cleaned and sucking air.[0004]2. Description of the Related Art[0005]In general, a vacuum cleaner includes a fan motor generating suction force, a suction head closely adhered to a surface to be cleaned and sucking air by the suction force of the fan motor, and a dust collector separating dust from the air sucked through the suction head and collecting the separated dirt, and thus performing cleaning.[0006]The fan motor and the dust collector may be accommodated in a main body, and the suction head may be connecte...
