Description
Technical Field
The invention relates to a cleaning device for cleaning a rotatable brush roller of a cleaning device. The invention also relates to a cleaning system comprising a cleaning device and a cleaning apparatus.
Background
Such a cleaning device is known from US8,819,882B2. In particular, for cleaning smooth floors, hand-held cleaning devices are used which have a base body with a shaft which is fastened in an articulated manner thereto, wherein the base body accommodates a rotatable roller assembly. The roller assembly is rotated by an electric motor integrated into the cleaning device, for example by an electric motor driven by a battery. The cleaning device is guided over the floor surface to be cleaned. In this case, the rotatable roller assembly releases dirt adhering to the ground. The cleaning device is further provided with a suction device having a suction gap, which is arranged adjacent to the roller assembly. The suction assembly receives dirt loosened by the brush assembly and conveys the dirt into a dirt container provided in the cleaning apparatus.
The cleaning device may also have means for applying a cleaning liquid to the floor surface to be cleaned. The cleaning liquid comes into contact with the brush roller, whereby the brush roller can also loosen firmly adhering dirt. In this case, there is the problem that dirt can accumulate on the brush roller over time. In order to remove dirt from the brush roller, it is known from the prior art to place the base body of the cleaning device in a basin-shaped cleaning device.
The cleaning device comprises a container with a recess adapted to receive a base body of the cleaning device provided with a brush roll. Furthermore, the cleaning device comprises a water reservoir in which the cleaning liquid is located. Here, the cleaning liquid is in contact with the brush roller. The brush roller of the cleaning device is rotated for cleaning. In this case, the cleaning liquid loosens dirt adhering to the brush roller and partially dissolved dirt reaches a dirt container arranged in the cleaning appliance via the suction gap.
Disclosure of Invention
The object of the invention is to provide a cleaning device for cleaning a rotatable brush roller of a cleaning device and a cleaning system having a cleaning device and a cleaning device, which allow a simple and improved cleaning of the brush roller.
The cleaning device according to the invention for cleaning a rotatable brush roller of a cleaning device comprises a container having a recess for receiving a base body of the cleaning device, which base body is provided with the brush roller, and a water reservoir, wherein the water reservoir is fluidically connected to the recess, wherein a cleaning liquid injected into the water reservoir flows automatically into the recess, wherein the recess is designed in such a way that the water reservoir is associated with an edge of the cleaning device which is at a distance from the brush roller, wherein the brush roller rests at least partially on the bottom of the recess, wherein the recess has a first recess for receiving the base body of the cleaning device, which first recess is arranged between the water reservoir and a second recess for receiving the brush roller, wherein at least one channel is introduced into the first recess, through which channel the cleaning liquid injected into the water reservoir automatically reaches the second recess, wherein at least one slit is introduced in a wall of the reservoir through which cleaning liquid filled into the reservoir reaches the at least one passage.
In the cleaning device according to the invention, it is advantageous if the cleaning liquid flows from the water reservoir gradually in the direction of the brush roller. Thereby preventing the brush roller from contacting an excessively large amount of cleaning liquid. Furthermore, the flow rate of the cleaning liquid can be adjusted such that the brush roller can be cleaned quickly and efficiently and contaminated cleaning liquid can be immediately conducted out of the recess. In most designs of the cleaning device, the edge referred to above is the rear edge of the cleaning device. In these cleaning devices, the hinged mounting of the handle is also located in the region of the rear edge.
The container forming the cleaning device is mostly placed on the floor for cleaning. Here, the distance from the water reservoir to the ground is greater than the distance from the recess to the ground. Thereby, the cleaning liquid can automatically flow from the reservoir into the recess by the action of gravity.
The recess may have a first recess for receiving a base body of the cleaning device and a second recess for receiving the brush roll, wherein the first recess is disposed between the water reservoir and the second recess. In this embodiment, the recess is adapted to the underside of the base body of the cleaning device, which enables effective cleaning of the brush roller. The second recess for receiving the brush roller is preferably designed in the form of a semicircular recess adapted to the shape of the brush roller.
The first cavity may have additional recesses for receiving wheels and the like.
In the first cavity, a passage can be introduced through which the cleaning liquid introduced into the reservoir reaches the second cavity automatically. The channel ensures that the cleaning liquid passes directly from the reservoir into the second cavity.
The second cavity may be provided with a protrusion. The protrusions can be configured as nodules, for example. The protrusions produce a point-like contact of the brush roller with the bottom of the second recess, which improves the cleaning action. Preferably, the projections are comb-shaped here. For this purpose, projections in the form of nodules are arranged, for example, in a comb-like manner in the lines. Such an arrangement of the protrusions enables a particularly thorough cleaning of the brush roller.
At least one slit can be introduced in the wall of the reservoir through which the cleaning liquid filled into the reservoir reaches the at least one passage. The at least one slit is preferably designed such that the volume flow of the cleaning liquid into the channel is independent of the filling level of the cleaning liquid in the reservoir. For this purpose, for example, the slot width of the slot can be varied in height-dependent fashion. Preferably, the gap width is chosen such that over a period of 30s approximately 100ml of liquid passes through the channel into the second cavity.
The cleaning system according to the invention comprises a cleaning device as described above and a cleaning device comprising a base body provided with a rotatable brush roll. The cleaning device preferably also comprises a handle which is connected to the base body in an articulated manner, a motor which rotates the brush roller, and a battery which supplies the motor with electrical energy.
Preferably, the base body is further provided with a suction device with a suction opening. The suction opening is preferably designed as a suction slot and is arranged adjacent to the brush roller on the underside of the base body facing the floor to be cleaned. The suction device is designed to receive dirt partially dissolved from the brush roller and to convey said dirt into a dirt container arranged in the base body.
The underside of the base body of the cleaning device and the bottom of the recess of the cleaning device are configured to substantially coincide with one another, so that the base body of the cleaning device can be at least partially inserted into the recess.
To clean the brush roller, a cleaning liquid is injected into the reservoir. The cleaning liquid flows into the second cavity via the slits and the channels. There, the cleaning liquid comes into contact with the rotating brush roller, wherein the brush roller also comes into contact with the projections arranged in the second recess, whereby the dirt is loosened and reaches the cleaning liquid. Due to the rotation of the brush roller, the contaminated cleaning liquid is conveyed in the direction of the suction opening of the cleaning appliance and is received there by the suction device and conveyed into a dirt container arranged in the cleaning appliance.

Detailed Description
Fig. 1 to 3 show a cleaning device 1 for cleaning a rotatable brush roller 13 of a cleaning device 11. The cleaning device 1 comprises a container 2 with a recess 3 which is adapted to receive a base body 12 of a cleaning device 11 provided with a brush roller 13. The container 2 further comprises a water reservoir 4, wherein the water reservoir 4 is in fluid connection with the recess 3.
The container 2 is constructed from injection-moldable plastic and has a circumferential rim 18 which delimits the recess 3 and the water reservoir 4. The edge 18 at the same time forms a resting surface so that the cleaning device 1 can be placed on a floor. The water reservoir 4 is arranged in the cleaning device 1 in such a way that it is arranged higher than the recess 3, as viewed from the floor on which the cleaning device 1 is arranged. Thereby, the cleaning liquid poured into the reservoir 4 automatically reaches the recess 3 under the action of gravity.
The recess 3 has a first cavity 5 for receiving the base body 12 of the cleaning device 11 and a second cavity 6 for receiving the brush roller 13. The first recess 5 is arranged here, seen in top view, between the reservoir 4 and the second recess 6. The brush roller 13 rests at least partially against the bottom 17 of the recess 6.
Three channels 7 are introduced in the first cavity 5, through which the cleaning liquid injected into the reservoir 4 automatically reaches the second cavity 6. Three slits 10 are introduced in the wall 9 of the reservoir 4, which are connected to the channel 7 and through which the cleaning liquid filled into the reservoir 4 reaches the channel 7.
In the cleaning device 1 according to the invention, the reservoir 4 and the second cavity 6 are opposite each other and are each associated with a surrounding edge 18. The first cavity 5 is located between the reservoir 4 and the second cavity 6.
The second cavity 6 is configured in the form of a cylindrical recess, wherein the second cavity 6 is provided with a projection 8 in the form of a nodule. In this case, the projections 8 in the form of nodules are arranged in the second recess 6 on the line and are therefore arranged in a comb-like manner. A total of three rows of comb-shaped projections 8 are arranged in the second recess 6.
In the region of the second recess 6, an emergency drain 19 is introduced in the rim 18 of the cleaning device 1. The emergency drain 19 comprises a third cavity which is separated from the second cavity 6 by a partition wall. Openings in the form of slits introduced in the bottom region are provided in the partition wall. The emergency drain 19 is connected in a fluid-conducting manner to the second recess 6 via said opening.
If the cleaning liquid flowing into the second cavity 6 cannot be accommodated by the cleaning apparatus 11, the cleaning liquid flows into the emergency drain 19 through the opening. In the edge 18, an opening in the form of two slot-shaped passages lying opposite one another is introduced in the region of the third recess. When the volume of the third cavity is used up, the cleaning liquid flows away via the through-openings.
The emergency drain 19 enables the cleaning liquid to flow out if the cleaning liquid is not discharged as intended, for example, if it is not received by the suction opening 15 of the cleaning device 11. This prevents the cleaning liquid from reaching mechanical or electrical components of the cleaning device 11 which are not designed to come into contact with the cleaning liquid.
The first cavity 5 has a recess 20 on the side facing the water reservoir 4, which is configured to receive a wheel 21 of the cleaning device 11.
Fig. 4 shows the cleaning device 11. The cleaning device 11 has a base body 12 which is provided with a rotatable brush roller 13. The cleaning device 11 is further provided with a suction device 14, wherein the suction device 14 has a suction opening 15 in the form of a suction slit. The suction opening 15 and the brush roller 13 are associated with a bottom 16 of the base body 12 facing the recess 3. The suction opening 15 and the brush roller 13 are arranged adjacent to one another, wherein the suction opening 15 is arranged at the front edge of the base body 12, followed by the brush roller 13. The suction device 14 contains a liquid and conveys it into a reservoir for containing a dirty liquid. The suction device 14 is detachably fixed in the housing unit to the cleaning apparatus 11.
The cleaning device 11 is also provided with means 23 for applying a cleaning liquid to the floor to be cleaned. Said means 23 are also associated with the bottom 16 of the base body 12.
The cleaning device 11 is equipped with an electric motor for driving the brush roller 13 and the suction device 14, wherein the electrical energy is supplied via a battery provided in the cleaning device 11.
The cleaning device 11 has a lever with a handle and an actuating switch for the electric motor of the suction device 14 and the brush roller 13, the lever being arranged in an articulated manner on the base body 12.
The brush roller 13 and the suction opening 15 are arranged in the bottom 16 in such a way that the brush roller 13 rests at least partially in the second cavity 6 and the suction opening 15 is located between the first cavity 6 and the edge 18.
Fig. 5 to 7 show a cleaning system 22 comprising a cleaning device 1 according to fig. 1 to 3. The cleaning system 22 shown here also comprises a cleaning device 11 according to fig. 4.
To clean the brush roller 13, cleaning liquid is injected into the reservoir 4. The cleaning liquid automatically reaches the second recess 6 via the gap 10 and the channel 7 by the action of gravity and comes into contact there with the rotating brush roller 13. The brush roller 13 is rinsed and simultaneously comes into contact with the protrusion 8 arranged in the second recess 6. The cleaning liquid with the dirt rinsed off from the brush roller 13 is conveyed in the direction of the suction opening 15 and is received by the suction opening 15 and conveyed into a dirt tank arranged in the cleaning device 11.
The suction opening 15 is associated with a cleaning strip 25 made of textile material. The cleaning strip 25 is assigned to the housing unit with the suction device 14 and can therefore be removed from the main body 12 together with the housing unit. Thereby, the cleaning strip 25 can be cleaned separately from the substrate 12. The cleaning strip 25 serves to seal the intermediate space between the base body 12 and the brush roller 13 on the side facing away from the suction opening 15. At the same time, the wiping result is homogenized by the cleaning strip 25 in the forward movement of the cleaning device 11.
