Definitions
- the invention relates to a cleaning device for cleaning a mechanical cleaning arrangement of a cleaning device, comprising a container with a recess for receiving the main body of the cleaning device provided with the cleaning arrangement.
- the invention further relates to a cleaning system comprising a cleaning device and a cleaning device.
- Such a cleaning device is known from US Pat. No. 8,819,882 B2.
- hand-held or autonomously moving cleaning devices which have a base body that accommodates a mechanical cleaning arrangement in the form of a rotatable brush arrangement.
- the cleaning arrangement is set in rotation by an electric motor arranged in the base body.
- the cleaning device moves over the floor to be cleaned and in doing so, by means of the rotating cleaning arrangement, loosens dirt adhering to the floor.
- the cleaning device can furthermore be provided with a suction device which has a suction slot which is arranged adjacent to the cleaning arrangement, the suction arrangement taking up the dirt loosened by the cleaning arrangement and conveying it into a dirt container located inside the main body.
- the cleaning device can also have a device for applying cleaning liquid to the floor to be cleaned. The cleaning liquid comes into contact with the cleaning arrangement, as a result of which the cleaning arrangement can also loosen firmly adhering dirt from the floor to be cleaned.
- the cleaning device comprises a container with a recess which is suitable for receiving the main body of the cleaning device provided with the cleaning arrangement. Furthermore, the cleaning device comprises a water reservoir in which there is a cleaning liquid. The cleaning liquid comes into contact with the cleaning arrangement. For cleaning, the cleaning arrangement of the cleaning device is set in motion, as a result of which the dirt adhering to the cleaning arrangement is loosened by means of the cleaning liquid. The loosened dirt gets into the dirt container of the cleaning device through the suction slot.
- the invention is based on the object of providing a cleaning device for cleaning a mechanical cleaning arrangement of a cleaning device and a cleaning system with a cleaning device and a cleaning device which enables improved cleaning of the cleaning arrangement.
- the cleaning device according to the invention for cleaning a mechanical cleaning arrangement of a cleaning device comprises a container with a recess for receiving the main body of the cleaning device provided with the cleaning arrangement, the recess being assigned a nozzle arrangement, the nozzle arrangement being connected to an inlet in a flow-conducting manner.
- Cleaning liquid can be fed to the cleaning device via the inlet, the cleaning liquid flowing out of the nozzle arrangement and cleaning the cleaning arrangement of the cleaning device there.
- the nozzle arrangement is accordingly arranged in the recess in such a way that it faces the cleaning arrangement of the cleaning device when the cleaning device is inserted into the cleaning device.
- the inlet makes it possible to supply a cleaning liquid from an external source to the cleaning device, it being possible for the supply to take place during the cleaning process. It is particularly advantageous that a cleaning liquid can be filled in with a pre-pressure via the inlet, so that the cleaning liquid leaves the nozzle arrangement in the form of a spray jet. This enables the cleaning arrangement to be cleaned particularly quickly and effectively.
- the inlet can be designed as a pipe coupling.
- the inlet can be designed in the form of a connector onto which a container with a water reservoir can be attached. Sealing means, for example in the form of an O-ring, can be assigned to the inlet.
- the nozzle arrangement can be connected to the inlet via at least one channel.
- the nozzle arrangement preferably comprises a plurality of nozzles which are arranged in the recess in such a way that all areas of the mechanical cleaning arrangement can be reached.
- the nozzles of the nozzle arrangement can be arranged next to one another in a row.
- the nozzles can, however, also be arranged in a grid.
- the cleaning liquid flows via the channel from the inlet in the direction of the nozzle arrangement with the nozzles and leaves the cleaning device via the nozzles.
- Flow-guiding devices can be arranged in the channel.
- the flow-guiding devices can cause the cleaning liquid to flow evenly out of all nozzles of the nozzle arrangement.
- the flow-guiding device is designed as a Tesla valve.
- a Tesla valve is a passive, fluidic valve in which the flow resistance in one flow direction is lower than in the opposite direction. It can thereby be achieved that the flow is given a preferred direction, which in the present case is the direction from the inlet to the nozzle arrangement. In the opposite direction, the flow resistance is significantly increased, so that the risk of cleaning fluid flowing back from the nozzle arrangement in the direction of the inlet can be reduced using simple means.
- the flow-guiding device can furthermore comprise a valve arrangement. It is particularly conceivable that check valves and the like are provided.
- Elevations can be arranged in the depression.
- the elevations can be designed as ribs or knobs, for example.
- the elevations result in point-like or linear contact between the cleaning arrangement and the elevations, which improves the cleaning effect.
- the elevations can be designed like a comb.
- the cleaning system comprises a cleaning device, as described above, and a cleaning device, comprising a base body which is provided with a mechanical cleaning arrangement.
- the cleaning device further comprises a water reservoir and an electric motor, which sets the cleaning arrangement in rotation, and an accumulator, which provides electrical energy for the electric motor.
- the cleaning device can furthermore comprise a pump device which conveys the cleaning liquid from the water reservoir in the direction of a nozzle.
- the mechanical cleaning arrangement can be a rotatable brush arrangement which has an axis of rotation which is aligned parallel to the floor to be cleaned.
- the brush can have plastic bristles, be formed from a fleece material or also from microfiber material.
- the cleaning arrangement can be a rotatable brush arrangement in which the axis of rotation is oriented perpendicular to the floor to be cleaned. It is conceivable that several, for example two, brushes are assigned to the base body. The brushes can have plastic bristles which are firmly connected to the brushes.
- removable pads made of cleaning textile can be attached to the brushes.
- the pads can be attached in particular via a Velcro connection done.
- the pad can be designed to be soft as well as firm and abrasive.
- the cleaning arrangement can be an oscillating cleaning arrangement in which the base body is assigned an oscillatable support body to which a pad is exchangeably attached.
- This cleaning arrangement performs an oscillating movement in the longitudinal and / or transverse direction for cleaning.
- the pad can be designed to be soft as well as firm and abrasive.
- the base body can also be provided with a suction device with a suction opening.
- the suction opening can be designed as a suction slot and can be arranged adjacent to the cleaning arrangement on the underside of the base body facing the floor to be cleaned.
- the suction device is designed to pick up dirt loosened by the cleaning arrangement and to convey it into a dirt container which is located in the main body of the cleaning device.
- the cleaning device is inserted into the recess of the cleaning device and the cleaning arrangement is set in motion. Cleaning liquid flowing in via the inlet flows out via the nozzle arrangement and the liquid jet flowing out of the nozzle arrangement cleans the cleaning arrangement of the cleaning device.
- the cleaning device can be provided with a liquid tank which comprises an outlet which can be connected to the inlet of the cleaning device for cleaning the cleaning arrangement.
- the outlet of the liquid tank is preferably designed to be congruent to the inlet and is arranged on the cleaning device in such a way that contact is made automatically when the cleaning device is inserted into the cleaning device.
- the outlet is a Associated with a valve which allows cleaning liquid to flow out of the liquid tank via the outlet only when the outlet is connected to the inlet of the cleaning device.
- the liquid tank can be pressurized. This can be done with simple means if the cleaning device is equipped with a pumping device. In this embodiment, a pressure can be built up via the pump device, which pressure is stored in the liquid tank. On the one hand, this enables cleaning liquid to flow out through the cleaning nozzle of the cleaning device and also a powerful flow of cleaning liquid over the nozzle arrangement of the cleaning device when the cleaning device is placed on the cleaning device.
- FIG. 5 shows a schematic diagram of a cleaning system
- FIG. 6 shows in detail the liquid tank of a cleaning device.
- Figures 1 and 2 show a cleaning device 1 for cleaning a mechanical cleaning arrangement 2 of a cleaning device 3, comprising a container 4 with a recess 5 for receiving the main body 6 of the cleaning device 3 provided with the cleaning arrangement 2.
- a nozzle arrangement 7 is assigned to the recess 5, the nozzle arrangement 7 being connected in a flow-conducting manner to an inlet 8.
- Inlet 8 is designed as a pipe coupling and protrudes from the container 4 in the form of a nozzle.
- cleaning liquid is introduced via the inlet 8, which liquid flows in the direction of the nozzle arrangement 7 and flows out through the nozzle arrangement 7.
- the nozzle arrangement 7 comprises a number of nozzles which are arranged in a line, the nozzles of the nozzle arrangement 7 being arranged in a V-shape when viewed from above.
- the nozzle arrangement 7 is connected to the inlet 8 via a channel 9.
- a flow-guiding device 10 in the form of a Tesla valve is arranged in the channel 9.
- elevations 11 are also arranged in the form of ribs, which are each arranged adjacent to the nozzles of the nozzle arrangement 7.
- the ribs are accordingly arranged in the shape of a comb in the recess 5.
- FIG. 3 shows a cleaning device 3 with a cleaning arrangement 2 which can be cleaned in the cleaning device 1.
- the cleaning device 3 has a base body 6 which is provided with a mechanical cleaning arrangement 2 in the form of a rotatable brush arrangement.
- the cleaning arrangement 2 comprises two disc-shaped brushes which are rotatably arranged on the underside of the base body 6. The axes of rotation of the brushes are each perpendicular to the underside of the base body 6, or perpendicular to the floor to be cleaned.
- the cleaning arrangement 2 comprises one or more brush rollers which are rotatably assigned to the underside of the base body 6, the brush rollers extending in sections into the base body 6.
- the axis of rotation of the brush rollers is parallel to the underside or to the floor to be cleaned.
- the cleaning device 3 is also provided with a suction device 15, the suction device 15 having a suction opening 18 in the form of a suction slot.
- the suction opening 18 and the cleaning arrangement 2 are assigned to the underside of the base body 6.
- the suction device 15 takes up dirty liquid and guides it into a dirty water container which is arranged in the interior of the base body 6.
- the suction device 15 with the dirty water container is detachably attached to the base body 6 in a housing unit.
- the cleaning device 3 is equipped with a further device 16 for applying cleaning liquid to the floor to be cleaned. Furthermore, the cleaning device 3 is equipped with electric motors for driving the cleaning arrangement 2 and the suction device 15, with the provision of the electrical energy taking place via an accumulator arranged in the base body 6.
- the cleaning device 3 also has a liquid tank 13, to which an outlet 14 is assigned, which can be connected to the inlet 8 for cleaning the cleaning arrangement 2.
- the cleaning device 3 also has a pumping device 17 which can apply pressure to the liquid tank 13. As a result, cleaning fluid can flow out of the further device 16 at high pressure on the one hand and leave the cleaning device 3 via the outlet 14 in order to subsequently exit the nozzle arrangement 7 of the cleaning device 1 and clean the cleaning arrangement 2.
- the outlet 14 is arranged on the cleaning device 3 in such a way that the outlet 14 automatically contacts the inlet 8 of the cleaning device 1 when the cleaning device 3 is inserted into the cleaning device 1.
- a valve arrangement is also assigned to the outlet 14, which valve arrangement only allows cleaning fluid to flow out of the outlet 14 when the outlet 14 is connected to the inlet 8.
- FIG. 4 shows a cleaning system 12 in which the cleaning device 3 is placed on the cleaning device 1, the outlet 14 of the liquid tank 13 contacting the inlet 8 of the cleaning device. Because the cleaning liquid in the liquid tank 13 is under pressure, the cleaning liquid flows via the outlet 14, the inlet and the channel 9 in the direction of the nozzle arrangement 7 and is sprayed there in the direction of the cleaning arrangement 2. The sprayed cleaning liquid is then taken up by the suction device 15.
- FIG. 5 shows a basic sketch of the cleaning system 12 with liquid tank 13, pumping device 17, device 16 for spraying cleaning liquid and nozzle arrangement 7.
- FIG. 6 shows in detail the liquid tank 13 of the cleaning device 3.
- the liquid tank 13 is a pressure tank and has an outlet 14, a device 16 for spraying cleaning liquid and a pumping device 17.
