Description

  The present invention relates to an appliance used in a floor cleaner that performs cleaning by spraying a cleaning liquid.

  Conventional floor cleaners or other similar devices that perform cleaning by spraying cleaning liquid are configured to supply cleaning liquid to the center of a rotating brush or other similar floor cleaning tool. However, in the case where the cleaning liquid is supplied to the center of such a brush or the like, dust tends to accumulate in the cleaning liquid supply tube, and the cleaning liquid supply tube may be clogged, which may hinder the function of the floor cleaner.

  To solve this problem, there is a solution in which the cleaning liquid supplied to the hub of the floor cleaner through the central tube is sprayed in the radial direction through the radial spray tube. For example, US Pat. No. 6,052,854A (Patent Document 1), US Pat. No. 5,711,051A (Patent Document 2), US Patent Application No. 2009 / 0260177A1 (Patent Document 3), US Patent See US Pat. No. 5,970,574 (Patent Document 4). However, since the cleaning liquid is supplied from the center of a brush or the like through a hose or tube, there is still a risk of clogging the hose or tube.

  In addition, the conventional floor cleaner requires an attachment means for attaching a rotary brush or the like to the floor cleaner and a suction means for sucking up dirty cleaning liquid from the floor after cleaning with the vacuum cleaner. It was complicated. This is particularly true for Patent Documents 1 to 4, and also for British Patent GB 2,345,241A (Patent Document 5).

  In addition, a small hub having a channel (flow path) for supplying a vacuum for sucking cleaning liquid from the floor to the floor cleaner is known, but such a conventional small hub is effective in a direction desired by a user. There is a problem that the direction cannot be changed, and rotation and other undesirable effects occur.

  Swedish patent SE529,868C2 (Patent Document 6) owned by the present applicant relates to a water suction device attached to a cleaning device. This water suction device has three suction nozzles (11) for sucking dirty cleaning liquid, and the suction nozzle is surrounded by one end of a blade (12, 13) for catching dirty cleaning liquid. It is.

  However, this prior art, which is configured to deliver cleaning liquid radially, includes a flow path for delivering cleaning liquid sprayed to the floor toward the center of the brush hub (18) and a cleaning liquid sprayed to the floor with a hose ( It is not configured to separate the flow path for delivery to the wastewater container (25) via 24). Since the cleaning liquid sprayed to the floor is supplied via the axial tube (14), the axial tube naturally becomes clogged.

  Accordingly, it is a primary object of the present invention to provide an apparatus designed for that purpose in order to solve some of the problems mentioned above.

  Said object is achieved by a hub device according to the invention. A hub device according to the present invention includes a hub member for supporting a disk-type brush of a floor cleaner, a hub member attached to the hub member and capable of rotating together with the hub member, and the hub member from the outside of the hub member. A movable channel member for supplying cleaning liquid, which is configured to spray cleaning liquid delivered radially toward the center of the hub member in a downward axial direction from the center of the hub member, and to the center of the hub member. A plurality of channel parts having two bent parts extending from a channel inlet connected and connected in a horizontal direction to a channel outlet connected in an upward direction through a part inclined obliquely upward, and sucked up from the floor A plug member configured to change the direction of the air flow for delivering the washed liquid to about 90 °, and a spring on the rotation center shaft of the hub member It is then attached, is disposed to surround the brush of the floor cleaner, and connected to a suction hose which connects to the channel inlet of the hub member, and a suction ring for sucking the cleaning liquid from the floor. The hub device of the present invention is (A) a function as a hub for supporting a disk-type brush, and (B) distributes cleaning liquid supplied in the radial direction from the outside of the hub member toward the center of the hub member. It has a function as a cleaning liquid distributor and (C) a function as a vacuum distributor that distributes vacuum in order to suck up the cleaning liquid sprayed from the floor cleaner to the floor.

  The hub device of the present invention is configured to fit a disk-type brush of a floor cleaner, a function of supplying a clean cleaning liquid, a function of supplying a vacuum for sucking the cleaning liquid from the floor, and a disk-type brush. It has three functions: a function for attaching to a floor cleaner. The hub device of the present invention supplies cleaning liquid to the center of the hub member via a movable channel member that rotates with the hub member. The movable channel member can deliver cleaning liquid without being obstructed by the spring system or the vacuum hose. The cleaning liquid is supplied from the body portion of the floor cleaner to the movable channel member via the nozzle. The cleaning liquid supplied to the movable channel member is delivered via the hub member, and is sprayed from the center of the brush to the floor.

  The hub device of the present invention solves the conventional problem that dust or the like adheres to the cleaning liquid supply tube and the tube is clogged. This conventional problem can be solved by changing the position of the cleaning liquid supply flow path to the peripheral portion of the hub member. The present invention also provides a floor cleaner that includes a suction ring that is attached to a rotating shaft via a spring and disposed around the brush. In a vacuum cleaner with the spring and suction tube, the cleaning liquid must be delivered under the brush through the channel so that the cleaning liquid does not splash around.

  In the hub device of the present invention, a detachable plug member is attached to the lower portion of the hub member so as to facilitate cleaning. The plug member can redirect the air flow for suction by approximately 90 degrees with minimal flow loss.
