Description

[Technical Field] The present disclosure relates to a cleaner system. [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 dust bin 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 providing a dust bin 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. Therefore, 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. Therefore, it is advantageous for cleaning a wide region 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. Recent vacuum cleaners tend to be miniaturized to maximize portability. Therefore, recently produced vacuum cleaners have a small capacity of a dust bin, causing the user's inconvenience having to empty the dust bin frequently. A vacuum cleaner station has been developed to solve the above-described inconvenience. The vacuum cleaner station is a device for holding the vacuum cleaner finishing cleaning and suctioning dust collected by the vacuum cleaner. That is, the dust collected by the cleaner is continuously collected in a dust collection part of the cleaner station, and the user empties the dust collection part of the cleaner station. Therefore, there is an advantage in that the number of times the user empties dust is drastically reduced compared to a case of emptying the dust bin of the vacuum cleaner every time. Meanwhile, Korean Patent Application Laid-Open No. 10-2022-0115253 discloses a cleaning device including a vacuum cleaner and a docking station. In the related art document, a filter capable of filtering ultrafine dust, etc. that is not filtered by a multi-cyclone inside a dust bin may be provided. However, since the filter is disposed inside a filter housing above the dust bin, there is a problem that it is difficult for a user to easily separate and clean the filter. That is, to allow the user to clean the filter, there is the inconvenience of having to separate the dust bin and then remove the filter from the filter housing. Likewise, to allow the user to clean the multi-cyclone, there is the inconvenience of having to first open or separate the dust bin and then separate the multi-cyclone from the dust bin. In this case, in the related art document, a flow rate change device may be provided. The flow rate change device is a component for selectively driving the amount of a suction airflow supplied to the dust bin so that a flow rate of air inside the dust bin is changed when a suction device of the docking station is driven. That is, the flow rate change device is configured to repeat supplying and blocking external air to the dust bin in a manner of providing air to the dust bin for a predetermined time and then blocking the supply of air for a predetermined time, thereby periodically changing the flow rate supplied to the inside of the dust bin. However, in the related art document, since a separate flow rate change device is configured to change the flow rate supplied to the inside of the dust bin by repeatedly opening and closing a flow path between a collection part and the suction device, large dust accumulated inside the dust bin may be strongly suctioned, but there is the limitation to removing dust accumulated in the filter disposed above the dust bin and the multi-cyclone disposed inside the dust bin. [Disclosure] [Technical Problem] The present disclosure has been made in efforts to solve the above problems and is directed to providing a cleaner system capable of easily removing dust accumulated in a filter and a second cyclone part without separating components of a cleaner.
