Benefits of technology

"The present disclosure provides a rotation brush driving apparatus for a vacuum cleaner that can selectively rotate the rotation brush using power of a motor in a simple structure. The apparatus includes a motor for generating suction force, a rotation brush, a belt for transmitting rotation force of the motor to the rotation brush, and a driving selection unit installed rotatably around the rotation shaft of the motor. The driving selection unit includes a bar shaped selection link and an idle pulley for selectively transmitting the rotation force of the motor to the rotation brush. The apparatus also includes a fixing unit for fixing the selection link to a predetermined position and a link supporting shaft for supporting the selection link so as to rotate in relation to the motor. The technical effects of the invention include simplifying the structure of the vacuum cleaner and improving the efficiency of the rotation brush driving."

Problems solved by technology

However, in a case that the rotation brush rotates in contact with a bare floor, the rotation brush may damage the bare floor.
However, there is a problem that cost for manufacturing the vacuum cleaner is increased as the vacuum cleaner with the above described structure is provided with the brush motor for driving the rotation brush 8 besides the main motor for generating suction force.
In addition, there is another problem that structure of the cleaner body is complicated and size of the cleaner body is large as the main motor and the brush motor are installed in the cleaner body 3.

Embodiment Construction

[0035]Hereinafter, certain exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0036]The matters defined in the description, such as a detailed construction and elements thereof, are provided to assist in a comprehensive understanding of the disclosure. Thus, it is apparent that the present disclosure may be carried out without those defined matters. Also, well-known functions or constructions are omitted to provide a clear and concise description of exemplary embodiments of the present disclosure.

[0037]FIG. 2 illustrates a case that a rotation brush driving apparatus 100 of a vacuum cleaner according to the present disclosure is installed in a suction nozzle 10 of an upright vacuum cleaner. FIG. 2 illustrates not cleaner body of the upright vacuum cleaner, but only the suction nozzle 10. A structure of the cleaner body of the upright vacuum cleaner using the rotation brush driving apparatus 100 according to the pre...

Abstract

The present disclosure relates to a rotation brush driving apparatus for a vacuum cleaner capable of selectively transmitting power of a motor to a rotation brush in a simple structure. The rotation brush driving apparatus for a vacuum cleaner according to the present disclosure includes a motor for generating suction force; a rotation brush; a belt for transmitting rotation force of the motor to the rotation brush; and a driving selection unit installed rotatably around the rotation shaft of the motor, for selectively transmitting the rotation force of the motor to the rotation brush by selectively contacting the belt with the rotation shaft of the motor.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit under 35 U.S.C. §119(a) from Korean Patent Application No. 10-2006-0124981 filed Dec. 8, 2006, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present disclosure relates to a vacuum cleaner, and more particularly, to a rotation brush for the vacuum cleaner.[0004]2. Description of the Related Art[0005]Generally, a vacuum cleaner is provided with a rotation brush for clearly removing dust attached to a surface to be cleaned such as a carpet and other surfaces. The rotation brush is rotated by force transmitted from a motor.[0006]However, in a case that the rotation brush rotates in contact with a bare floor, the rotation brush may damage the bare floor. In other words, the rotation brush increases a roughness of a smoothly processed surface of the bare floor and decre...
