Description

[Technical Field] The present invention relates to a cleaner. [Background Art] In general, a cleaner is a home appliance for suctioning small trash or dust in a manner of suctioning air using electricity and filling the same in a dustbin inside a product and is commonly called a vacuum cleaner. The vacuum cleaner may be classified into a manual vacuum cleaner for allowing a user to directly perform cleaning while moving the cleaner, and an automatic vacuum cleaner for performing cleaning while traveling by itself. Depending on the type of the vacuum cleaner, the manual vacuum cleaner may be classified into a canister-type vacuum cleaner, an upright vacuum cleaner, a hand vacuum cleaner, a stick-type vacuum cleaner, etc. In the past, the canister-type vacuum cleaner was widely used as the household vacuum cleaner, but recently, the hand vacuum cleaner and the stick-type vacuum cleaner, which provide improved convenience of use by integrally providing a dustbin and a cleaner body, are increasingly being used. The canister-type vacuum cleaner has a main body and a suction port connected by a rubber hose or a pipe and in some cases, may be used by inserting a brush into the suction port. The hand vacuum cleaner is designed to maximize portability and has lightweight and a short length, and thus can have a limited cleaning area. Accordingly, the hand vacuum cleaner is used to clean localized sites, such as on a desk, a sofa, or a vehicle interior. A user may use the stick-type vacuum cleaner while standing to enable cleaning without bending down. Accordingly, it is advantageous in cleaning a wide area while moving. While the hand vacuum cleaner cleans narrow spaces, the stick-type vacuum cleaner may clean wider spaces and clean high places out of reach. Recently, the stick-type vacuum cleaner has been provided in a module type to allow users to actively change a vacuum cleaner type for various purposes. Meanwhile, Korean Patent Laid-Open Application No. 10-2098784 discloses a cleaner. The cleaner disclosed in the patent document may include a filter unit for filtering dust from air discharged from a cyclone unit and a moving unit for removing dust from an outer surface of the filter unit while moving in a linear direction. However, the patent document discloses only a structure for removing dust accumulated on an outer surface of a single filter for filtering dust from air introduced through a suction unit and does not disclose a structure for removing dust accumulated on an outer surface of each filter in a cleaner provided with a plurality of filters. In particular, when the plurality of filters are disposed inside a main body above a dustbin, it is difficult for a user to easily remove and clean the filter. That is, when a separate filter is disposed inside the main body in addition to the filter unit disclosed in the patent document, the user needs to first remove the dustbin and a second cyclone unit from the main body to clean the filter, which is cumbersome. [Disclosure] [Technical Problem] The present invention has been made in efforts to solve the above problems and is directed to providing a cleaner capable of removing dust accumulated in at least one filter with only a simple operation of a user pushing or pulling an operation unit. In addition, the present invention is directed to providing a cleaner capable of improving filtration performance of a filter and suction performance by a suction motor by directly sweeping a surface on which dust accumulates among outer and inner surfaces of each filter. In addition, the present invention is directed to providing a cleaner capable of preventing dust stored inside a dustbin from being scattered to the outside through an open upper side of the dustbin when a user pulls or pushes an operation unit to remove the dustbin from a support of a main body housing. In addition, the present invention is directed to providing a cleaner in which a second cleaning member is connected to a dustbin and an operation unit is fixed to the dustbin, thereby enabling the dustbin in which a first cleaning member is disposed to move more stably when a user pulls or pushes the operation unit. In addition, the present invention is directed to providing a cleaner in which a second cleaning member is connected to an operation unit and the operation unit is fixed to a dustbin, thereby enabling the second cleaning member to move without shaking when a user pulls or pushes the operation unit, thereby improving operability. In addition, the present invention is directed to providing a cleaner which may have a structure in which a first cleaning member for sweeping dust accumulated in a first filter, a second cleaning member for sweeping dust accumulated in a second filter, and a third cleaning member for sweeping dust accumulated in a third filter are connected to each other, thereby removing dust accumulated in each filter by only moving an operation unit. In addition, the present inven
