Abstract

A brush assembly of a cleaner includes a driving motor mounted at a cleaner main body, for generating a rotary force; a brush rotatably disposed at a suction opening formed at the cleaner main body; and a driving force transfer device installed between the driving motor and the brush, rotating the brush by transferring a rotary force of the driving motor to the brush, and protecting the driving motor by preventing transfer of a load generated at the brush to the driving motor. Accordingly, the driving motor can be continuously rotated even if the brush cannot be rotated by being caught by a stuff or the like, thereby preventing motor damage.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a brush assembly of a cleaner, and particularly, to a brush assembly of a cleaner capable of preventing motor damage by keeping the motor rotating when a brush cannot be rotated by being caught by a stuff or the like. [0003] 2. Description of the Background Art [0004] In general, a robot cleaner performs a cleaning operation while moving for itself without manipulation of a user, moves to a charging station if power of a battery is consumed during cleaning, and moves back to a cleaning zone to perform a cleaning operation when the battery charge is completed. [0005] A brush assembly for sweeping up dirt or foreign substances from a floor is installed at a suction opening through which dirt is sucked, of the robot cleaner. [0006]FIG. 1 is a side view showing a brush assembly of a robot cleaner in accordance with the conventional art. [0007] The brush assembly in accordance with the co...
