Problems solved by technology

That is, since the fine dust clogs the fine mesh of the filter 13, it is difficult to discharge the sucked air and eventually the suction force decreases
Therefore, if the filter 13 is not cleaned or replaced regularly, the cleaning operation cannot be effectively performed due to the reduced suction force.

Abstract

A filter device for a vacuum cleaner comprises: a casing having a collecting space therein, a suction opening through which air including dust is sucked, formed eccentrically at one side so that sucked air can be rotated and a discharge opening through which purified air is discharged; a filter installed at an internal space of the casing, for filtering dust from air sucked through the suction opening; a filter cleaning unit disposed at an outer circumferential surface of the filter, for cleaning the filter by being rotated by a rotation force of air sucked through the suction opening; and a rotation restraining means for restraining rotation of the filter cleaning unit when the filter cleaning unit reaches a top dead point. Accordingly, fine dust attached to the filter in cleaning is removed so that a channel of the filter can be prevented from being closed.

Description

technical field [0001] The present invention relates to a vacuum cleaner, and more particularly, to a filter device of a vacuum cleaner capable of automatically removing dust attached to a filter during operation of the vacuum cleaner. Background technique [0002] Generally, a vacuum cleaner is an electronic device used to clean an indoor space such as a room, an office, or a car, and can use its suction power to remove unwanted impurities such as dust existing in a home or a car. [0003] figure 1 Shown is a perspective view of the structure of a common vacuum cleaner. [0004] As shown in the figure, a common vacuum cleaner includes a vacuum cleaner body 1 and a suction head 3, which is connected to the vacuum cleaner body 1 through a suction hose 5 and a telescopic tube 4 for sucking dust and foreign objects on the floor. [0005] The cleaner main body 1 includes a suction generating portion (not shown) for generating suction; and a filter device 6 for collecting dust ...
