Definitions

  • the present disclosure relates to a cleaner station, and more particularly, to a cleaner station configured to capture dust in a cleaner and equipped with a bagless type dust collecting part.
  • a cleaner refers to an electrical appliance that draws in small garbage or dust by sucking air using electricity and fills a dust bin provided in a product with the garbage or dust.
  • a vacuum cleaner Such a cleaner is generally called a vacuum cleaner.
  • the cleaners may be classified into a manual cleaner which is moved directly by a user to perform a cleaning operation, and an automatic cleaner which performs a cleaning operation while autonomously traveling.
  • the manual cleaners may be classified into a canister cleaner, an upright cleaner, a handy cleaner, a stick cleaner, a robot cleaner, and the like.
  • the canister cleaners were widely used in the past as household cleaners. However, recently, there is an increasing tendency to use the handy cleaner and the stick cleaner in which a dust bin and a cleaner main body are integrally provided to improve convenience of use.
  • the canister cleaner In the case of the canister cleaner, a main body and a suction port are connected by a rubber hose or pipe, and in some instances, the canister cleaner may be used in a state in which a brush is fitted into the suction port.
  • the handy cleaner (hand vacuum cleaner) has maximized portability and is light in weight. However, because the handy cleaner has a short length, there may be a limitation to a cleaning region. Therefore, the handy cleaner is used to clean a local place such as a desk, a sofa, or an interior of a vehicle.
  • a user may use the stick cleaner while standing and thus may perform a cleaning operation without bending his/her waist. Therefore, the stick cleaner is advantageous for the user to clean a wide region while moving in the region.
  • the handy cleaner may be used to clean a narrow space, whereas the stick cleaner may be used to clean a wide space and also used to a high place that the user's hand cannot reach.
  • modularized stick cleaners are provided, such that types of cleaners are actively changed and used to clean various places.
  • a robot cleaner which autonomously performs a cleaning operation without a user's manipulation, is used.
  • the robot cleaner automatically cleans a zone to be cleaned by sucking foreign substances such as dust from the floor while autonomously traveling in the zone to be cleaned.
  • the robot cleaner is generally designed to have a small size to perform a cleaning operation while autonomously traveling, a capacity of a dust bin for storing the collected dust, which inconveniences the user because the user needs to empty the dust bin frequently.
  • a cleaner station has been developed to cope with the inconvenience.
  • the cleaner station refers to a device configured to accommodate the robot cleaner, which has completed the cleaning operation, and to suck the dust collected by the robot cleaner.
  • the cleaner station is equipped with a dust collecting part much larger in size than the dust bin of the robot cleaner. That is, the dust collected by the robot cleaner is continuously captured in the dust collecting part of the cleaner station, and the user empties the dust collecting part of the cleaner station.
  • the configuration using the cleaning station has an advantage in that the number of times the user empties the dust bin rapidly decreases in comparison with a case in which the user frequently empties the dust bin of the robot cleaner.
  • the dust collecting parts are broadly classified into a bag type dust collecting part and a bagless type dust collecting part.
  • the bag type dust collecting part is equipped with a separate bag, the bag captures dust, and a user separates only the bag from the cleaner station and discards the bag.
  • the bagless type dust collecting part is not equipped with a separate bag, the dust collecting part captures dust, and a user separates the dust collecting part from the cleaner station and eliminates the dust.
  • the bag is a single-use consumable component and is generally made of vinyl materials, costs are required to purchase the bag every time, and the bag causes an environmental problem such as environmental pollution. Therefore, the bagless type dust collecting part is often installed in the cleaner station in order to solve the above-mentioned problems.
  • a predetermined or larger amount of dust is collected in the cleaner, and the dust primarily collected by the cleaner is introduced into the cleaner station. For this reason, a large amount of dust may be introduced into the cleaner station at one time. In this case, in case that a large amount of dust is introduced into the bagless type dust collecting part at one time, there may occur a problem in that a flow path is instantaneously clogged, which degrades the dust capturing function of the cleaner station.
  • the station As Related Art 1, there is a discharge station configured to empty a dust bin of a robot cleaner.
  • the station according to Related Art 1 includes a base configured to accommodate the robot cleaner equipped with the dust bin, and a canister in which a dust capturing part is disposed.
  • the dust contained in air introduced into the station of Related Art 1 is primarily filtered out by a filter while moving radially inward and secondarily filtered out by a cyclone part.
  • Related Art 2 there is a station configured to be docked with a cleaner and equipped with a detachable dust capturing bin.
  • Related Art 2 provides a station housing, a bagless type dust capturing bin equipped with a cyclone part, and a detachable filter. According to Related Art 2, the dust capturing bin may be attached to or detached from the station.
  • Related Art 2 merely provides several embodiments related to the methods of docking the cleaner to the station or the methods of attaching or detaching the dust capturing bin but does not show a solution for solving the problem in that the flow path is clogged by a large amount of dust introduced into the station at one time.
  • An object of the present disclosure is to provide a cleaner station equipped with a bagless type dust collecting part capable of preventing a flow path from being clogged even when an excessively large amount of dust is temporarily introduced at one time.
  • Another object of the present disclosure is to provide a cleaner station equipped with a dust collecting part capable of capturing a maximum amount of dust when a capacity remains the same.
  • Still another object of the present disclosure is to provide a cleaner station equipped with a prefilter capable of ensuring a minimum airflow even when a predetermined or larger amount of dust is introduced.
  • a cleaner station includes a housing, a coupling part disposed in the housing and including a coupling surface to which at least a part of a cleaner is coupled, and a dust collecting part accommodated in the housing and configured to capture dust in a dust bin of the cleaner.
  • the dust collecting part includes a dust collecting body, a mesh, and a compression plate.
  • the dust collecting body defines an external shape and has an internal space in which dust is collected.
  • the dust collecting body has an air inlet port through which air is introduced into the internal space, and an air discharge port through which the air in the internal space is discharged.
  • the dust collecting part includes the mesh configured to cover the air discharge port, and the compression plate rotatably disposed in the internal space of the dust collecting body and configured to clean the mesh while rotating.
  • the air inlet port may be formed in one of a bottom surface, an outer wall surface, and an upper surface of the dust collecting body, and the air discharge port may be formed in one of the bottom surface, the outer wall surface, and the upper surface of the dust collecting body, except for the surface in which the air inlet port is formed.
  • the air discharge port may be formed in the upper surface of the dust collecting body.
  • the dust collecting body may include a shaft disposed in the internal space and extending in a longitudinal direction, and the outer wall surface of the dust collecting body may be formed in a cylindrical shape based on the shaft.
  • the compression plate may include a stationary plate extending from the outer wall surface of the dust collecting body toward the shaft, and a rotary plate rotatably coupled to the shaft and extending radially outward.
  • the dust collecting part may be disposed to be mounted or detached in a direction of one side of the housing.
  • the cleaner station may include a handle rotatably coupled to the dust collecting part.
  • a rotation center axis of the handle may be disposed to be in parallel with a rotation center axis of the compression plate.
  • the cleaner station may include a prefilter disposed above the dust collecting part and configured to communicate with the air discharge port of the dust collecting part.
  • the prefilter may be coupled or detached in a direction inconsistent with a direction in which the dust collecting part is coupled or detached.
  • the cleaner station may include a suction flow path having an inlet end communicating with the dust bin of the cleaner, and an outlet end communicating with the air inlet port of the dust collecting part.
  • the outlet end of the suction flow path may be disposed above the inlet end of the suction flow path.
  • the cleaner station may include a discharge flow path having an inlet end communicating with the air discharge port of the dust collecting part, and an outlet end communicating with the outside at one side of the housing.
  • the outlet end of the discharge flow path may be disposed below the inlet end of the discharge flow path.
  • the dust collecting part may include a cyclone part disposed on an outer peripheral surface of the dust collecting body and configured to communicate with the air discharge port and separate the dust from the air by using a centrifugal force.
  • the cleaner station may further include: a dust collecting motor configured to generate a flow of air and disposed between the cleaner and the dust collecting part when the cleaner is coupled.
  • the cleaner station of the present disclosure has one or more of the following effects.
  • the rotary plate rotates in the dust collecting body and moves the dust to the space in which no air flows, such that the airflow in the dust collecting body is not hindered even when an excessively large amount of dust is temporarily introduced at one time.
  • the rotary plate rotates in the dust collecting body and compresses the dust in the dust collecting body, such that the volume of the captured dust may be reduced, and the dust may be additionally captured.
  • the rotary plate rotates in the dust collecting body and wipes away the dust attached to the mesh of the air discharge port, such that an air flow rate is maintained to a performed degree or higher in the mesh.
  • the air flows upward in the filtering member of the prefilter, such that the dust is filtered out by the lower surface of the filtering member, and the dust having a predetermined weight or heavy is dropped to the lower portion of the filtering member by gravity. Therefore, it is possible to ensure the minimum airflow in the prefilter.
