Definitions

  • the present invention relates to a robot cleaner comprising a brush cover lock mechanism.
  • Robot cleaners comprise a roller brush disposed in a cavity at the bottom.
  • a brush cover with grids is mounted on the mouth of the cavity in order to protect the brush and increase cleaning performance.
  • the brush cover is detachably mounted on the bottom of the robot cleaner body.
  • robot cleaners are designed to have bases close to the surface to be cleaned, on which they move mainly in forward-rear direction. As a result of the motion and bumping with objects on the floor, the brush cover can get loose or open during cleaning, causing inconvenience for the user. Also, due limited space between the brush and the cover, it is difficult to grip and take the brush cover off from the body. Dirt accumulated on brush surface makes holding the brush cover even more inconvenient for a user.
  • Chinese patent application CN203483356U discloses a vacuum cleaner comprising a rolling brush at its bottom and a rolling brush cover plate thereon. By using a locking element and a button element arranged to move in rear-forward direction, the cover plate can be locked and unlocked.
  • Chinese patent application CN210871288U discloses a robot cleaner with a rolling brush cover detachable connected to its base. The base is provided with two buckle assemblies for locking the brush cover to the base.
  • the aim of the present invention is realization of a robot cleaner overcoming the disadvantages in the prior art in a simple and cost-effective manner. More specifically, the present invention proposes a robot cleaner wherein a brush cover is firmly secured to the base of the robot cleaner in locked state and can be conveniently removed from thereof in its unlocked state, thus increasing cleaning performance and customer satisfaction.
  • the robot cleaner realized in order to attain the aim of the present invention, defined in Claim 1 and the respective claims thereof, comprises a body, a roller brush disposed in a cavity at the bottom of the body, a brush cover detachably connected to the bottom of the body, and a locking mechanism for locking/unlocking the brush cover to/from the body.
  • the locking mechanism comprises at least one locking hole, at least one protrusion which sits in the locking hole in locked state of the brush cover, and at least one slide button for locking and unlocking the brush cover.
  • the locking mechanism further comprises a release means comprising an inclined surface, and a contact portion for abutting against the inclined surface.
  • the release means and the contact portion are arranged such that, when the slide button is moved from a locking position to an unlocking position, the release means and the contact portion slide with respect to one another, pushing the brush cover away from the body. In this way, as the button is slid to unlock the brush cover, the brush cover is automatically made ajar and moved away from the body and the roller brush. This allows a user to hold the brush cover more easily without touching the roller brush.
  • the button is arranged to slide in right-left direction. Since this is perpendicular to the main moving direction (rear-front) of a robot cleaner, chances of the brush cover getting loose or open during cleaning is minimized.
  • the locking mechanism may further comprise at least one flexible arm extending from the release means and at least two seats for accommodating the free end of said arm, respectively, in locked and unlocked positions. Accordingly, the sliding parts of the locking mechanism can be hold firmly in both locked and unlocked positions without using additional biasing means such as springs. Use of arms and seats also allows a more compact locking mechanism design.
  • the button is slidably mounted on the body.
  • the protrusion may be disposed on a part of the locking mechanism arranged to slide with the sliding movement of the button, and the hole may be disposed on the brush cover or on an extension thereof.
  • the release means may be disposed on a part of the locking mechanism arranged to slide with the sliding movement of the button, and the contact portion may be disposed on the brush cover or on an extension thereof.
  • the seats may be disposed on the body, for example on an inner surface of its base.
  • the locking mechanism may further comprise at least one stopper for limiting the sliding movement of the button in the direction of unlocking. The stopper provides additional means for limiting the sliding movement of the button, in addition to or as an alternative to arm-seat structure.
  • the release means is preferably mechanically coupled to the button to slide with the button, such that the release means remains within the body. As a result, while the button is visible and accessible from bottom of the body, the release means is not.
  • the locking mechanism may further comprise a connecting means, such as a screw, for connecting the release means and the button.
  • the release means and the button may also be connected via a snap-fit connection.
  • the release means is preferably formed as one piece with the protrusion and/or at least one flexible arm extending from the release means.
  • the robot cleaner (1) comprises a body (2); a roller brush (3) disposed in a cavity at the bottom of the body (2); a brush cover (4) detachably connected to the bottom of the body (2); and a locking mechanism (5) for locking/unlocking the brush cover (4) to/from the body (2) ( Figure 1 ).
  • the brush cover (4) comprises grids to partly cover the opening of the cavity, to protect the roller brush (3) while allowing the roller brush (3) touch the surface to be cleaned ( Figure 2 ).
  • the locking mechanism (5) comprises at least one locking hole (7), at least one protrusion (6) which sits in the locking hole (7) in locked state of the brush cover (4), and at least one slide button (8) for locking and unlocking the brush cover (4).
  • the slide button (8) is arranged to be moved with respect to the body (2) and the brush cover (4), between locking and unlocking positions.
  • the locking mechanism (5) further comprises a release means (9) comprising an inclined surface (10), and a contact portion (11) for abutting against the inclined surface (10).
  • the release means (9) and the contact portion (11) are arranged such that, when the slide button (8) is moved from a locking position to an unlocking position, the release means (9) and the contact portion (11) slide with respect to one another, pushing the brush cover (4) away from the body (2).
  • One of the release means (9) and the contact portion (11) is disposed on a part of the locking mechanism (5) arranged to slide with the sliding movement of the button (8), for example on an extension of the button (8) or a part connected to the button (8), and the other is disposed on the brush cover (4), for example on an extension of the brush cover (4) or a part connected to the brush cover (4).
  • the inclined surface (10) is inclined with respect to the sliding direction.
  • the sliding direction is preferably parallel to the base of the body (2). While one of the release means (9) and the contact portion (11) can make a sliding motion, the other is displaced in a direction orthogonal to the sliding direction ( Figures 3 and 4 ).
  • the contact portion (11) is positioned to abut against the inclined surface (10) all along the sliding movement.
  • the sliding motion of one of the inclined surface (10) and the contact portion (11) over the other during unlocking causes the brush (4) cover to be displaced away from the bottom of the body (2).
  • the brush cover (4) can be properly placed on the base of the body (2) by moving the button (8), hence the inclined surface (10) or the contact portion (11), in the locking direction.
  • the robot cleaner (1) preferably comprises at least two wheels extending in rear-front direction.
  • the main direction of movement is therefore forward and rearward.
  • the button (8) is arranged to slide in a direction perpendicular to main movement direction of the robot cleaner (1), for instance sliding in left-right direction.
  • the locking mechanism (5) further comprises at least one flexible arm (13) extending from the release means (9) and at least two seats (12) for accommodating the free end of said arm (13), respectively, in locked and unlocked positions.
  • the button (8) is slidably mounted preferably on the body (2). That is, the button (8) is fixed to the body (2) even when the brush cover (4) is removed therefrom. Alternatively, the button (8) may be slidably mounted on the brush cover (4), being attached to and detached from the body (2) with the brush cover (4).
  • the protrusion (6) is preferably disposed on a part of the locking mechanism (5) arranged to slide with the sliding movement of the button (8), that is, directly on, on an extension of, or on a part mechanically coupled to the button (8).
  • the hole (7) is disposed on (or on an extension of) the brush cover (4).
  • the hole (7) may be coupled to a sliding part and protrusion to the brush cover (4).
  • the release means (9) is preferably disposed on a part of the locking mechanism (5) arranged to slide with the sliding movement of the button (8), that is, directly on, on an extension of, or on a part mechanically coupled to the button (8).
  • the contact portion (11) is disposed on (or on an extension of) the brush cover (4).
  • the seats (12) are disposed on the body (2).
  • the contact portion (11) may be coupled to a sliding part and the release means (9) to the brush cover (4).
  • the locking mechanism (5) may further comprise at least one stopper (14) for limiting the sliding movement of the button (8) in the direction of unlocking.
  • a rectangular housing is provided on an inner surface of body (2), wherein the seats (12) are formed at the side walls of the housing and a rear wall of the housing functions as the stopper (14).
  • the release means (9) may be mechanically coupled to the button (8) to slide with the button (8), such that the release means (9) remains within the body (2).
  • the locking mechanism (5) may further comprise a connecting means (15), such as a screw, for connecting the release means (9) and the button (8).
  • the robot cleaner (1) of the present invention provides a simple and cost-effective solution for conveniently locking a cover plate (4) on the body (2), and likewise easily unlocking and removing the cover plate (4) therefrom.
  • the sliding movement of the button (8) in locking direction provides a concurrent locking and placement of the brush cover (4)
  • the sliding movement of the button (8) in unlocking position provides a concurrent unlocking and displacement of the brush cover (4) for a more convenient removal of the same.
