Definitions
- the invention relates to a cleaning device, in particular a floor cleaning device, with a rotating about a rotation axis cleaning roller for processing a surface to be cleaned, wherein the cleaning roller is at least partially formed as a hollow body with an internal liquid space, wherein the hollow body at least one hollow body opening for the discharge of liquid from the liquid space.
- the publication DE 20 2007 017 026 U1 discloses, for example, a floor cleaning device with a cleaning roller designed as a wiping roller, which is supplied with cleaning fluid from the inside.
- the cleaning roller on a liquid-permeable hollow body. This is provided for moistening an externally applied to the cleaning roller cleaning cloth with openings, for example in the form of holes, slots, holes and the like.
- the cleaning cloth and / or an optionally arranged between the hollow body and the cleaning cloth sponge body is formed absorbent, so that permanently liquid is sucked from the hollow body through the openings. Due to the contact pressure during a displacement of the cleaning device over the surface to be cleaned, the liquid from the cleaning cloth or the
- a disadvantage is that from the liquid space of the cleaning roller permanently liquid is discharged to the surface of the hollow body, that is also to the cleaning cloth and / or the sponge body. Thus, liquid is dispensed even if the cleaning roller is currently not used for a cleaning process, but for example, is only transported.
- the invention proposes that the hollow body opening is assigned a mechanically actuable valve element, which depends on the amount of a centrifugal force acting on the valve element due to rotation of the cleaning roller into a closed position closing the hollow body opening and / or in FIG a the hollow body opening releasing opening position is displaced.
- valve element centrifugal force it depends on the force acting on the valve element centrifugal force, whether liquid is discharged from the liquid space to the surface of the hollow body or not.
- mechanically operable valve element thus refers to an automatically force-dependent valve and not manually operated by a user valve. This is based on the knowledge that during a rotation of the cleaning roller a speed-dependent centrifugal force acts on the valve element, which presses the liquid contained in the hollow body radially outward against the valve element. As soon as the centrifugal force reaches the closing force of the valve Tilelementes predominates, opens the valve element for leakage of liquid from the liquid space.
- the force acting on the valve element centrifugal force of the mass of the liquid, the mass of the valve element, the distance of the liquid or the valve element to the axis of rotation x and the rotational speed of the cleaning roller depends.
- a minimum centrifugal force defined by the current parameters of the cleaning roller and the liquid is exceeded, the hollow body opening is released by the valve element.
- the valve element is moved from the closed position to the open position. It is proposed that the valve element is formed, from reaching a minimum speed of the cleaning roller to allow leakage of liquid from the liquid space. In otherwise constant parameters, the displacement of the valve element from the closed position to the open position, and vice versa, exclusively depends on the rotational speed of the cleaning roller about the axis of rotation.
- a minimum speed is defined, beyond which the valve element is displaced into the open position and thus a discharge of liquid from the liquid space is possible. It is advisable to keep the amount of liquid within the liquid space constant, ie to refill a corresponding amount of liquid when dispensing liquid through the hollow body openings. If the defined minimum speed is not reached, ie the cleaning roller rotates at a lower speed, the liquid can not reach the surface of the hollow body from the liquid space. Thus, it can be controlled in a targeted manner via the speed setting of the cleaning roller, when liquid emerges from the hollow body and when not. During a mere transport of the cleaning device, in which the cleaning roller usually does not rotate, the discharge of liquid can thus be effectively prevented.
- the cleaning roller for a cleaning Operation which requires the use of liquid, rotates at a speed exceeding the minimum speed, so that the centrifugal force, the valve element displaced into the open position and liquid can be delivered to the surface to be cleaned.
- an empty liquid space can also be assumed (conservatively) if no permanent refilling of liquid into the liquid space is provided.
- the valve element is associated with a restoring element, in particular a spring, and / or the valve element is designed as a return actuator, wherein the restoring force of the restoring element counteracts the centrifugal force in the direction of the closed position.
- the restoring force of the return element counteracts the force acting on the valve element centrifugal force.
- the restoring element can be formed separately from the valve element, for example in the form of a separate compression spring, tension spring, torsion spring or the like.
- the valve element itself may be formed as a restoring element or have the restoring element as an integral part.
- the valve element may be formed of an elastic material which is at least partially displaceable due to the centrifugal force.
- the valve element may have a film hinge or be formed elastically in the edge region of the hollow body opening, so that a displacement due to the attacking centrifugal force is possible.
- the restoring element is in each case designed so that the restoring force at a defined speed of the cleaning roller is less than the attacking centrifugal force, so that the valve element opens when the minimum speed is exceeded.
- an empty liquid space without liquid.
- the valve element has at least one pivotally mounted on the hollow body closure element.
- This pivotally arranged closure element may, for example, be a pivotable valve flap which is arranged on the edge region of the hollow body delimiting the hollow body opening.
- the valve element can either have only one pivotally arranged closure element, ie, for example, only one valve flap, or a plurality of closure elements.
- the closure element or the closure elements can be offset relative to the surface of the hollow body radially inward or radially outward, so that they are flush with the outer or inner surface of the hollow body.
- the pivotable closure element can either be a separate closure element fastened to the hollow body, or be formed integrally with the hollow body, for example as a film hinge, elastic edge region of the hollow body or the like.
- valve element has a linearly movable, in particular slidingly movable, arranged on the hollow body closure element.
- the closure element is arranged in the closed position of the valve element in front of the hollow body opening and can be spaced from the hollow body opening by a movement directed perpendicular to the plane of the hollow body opening.
- the closure element is arranged on a free end region of a restoring element, in particular a spring, whose restoring force acts perpendicular to the plane of the hollow body opening.
- the closure element When a certain amount of centrifugal force is exceeded, the closure element is thus removed from the hollow body opening counter to the restoring force of the restoring element, so that a flow path for the liquid flowing out of the hollow body forms between the hollow body opening and the closure element.
- the valve element is an elastically formed, the hollow body opening limiting edge region of the hollow body.
- the hollow body at least in the edge region of the hollow body opening to an elastic material, so that the edge region due to the attacking centrifugal force radially outward (relative to the hollow body) moves and the hollow body opening is increased.
- the elastic edge region is advantageously designed so that an escape of liquid through the hollow body opening is not possible. This can be achieved by overlapping partial areas of the edge area in the closed position. In the open position, the edge regions are spaced apart from each other and the hollow body opening is released.
- the hollow body may be formed of an at least partially elastic membrane, wherein at least one hollow body opening is contracted in the closed position and pressed apart in the open position.
- the hollow body can thus be formed from a membrane which, for example, has needle-shaped hollow body openings which open more or less depending on the amount of the attacking centrifugal force and thus release a flow path for liquid from the hollow body.
- the hollow body openings are thus contracted punctiform in the closed position and pressed apart in the open position.
- a material having a modulus of elasticity which allows rapid opening and closing of the hollow body opening in response to a change in the amount of centrifugal force.
- rubbery materials are suitable.
- an at least partially elastic membrane which has at least one membrane opening, is provided on the hollow body.
- the hollow body is preferably formed from a hard plastic and coated with an elastic, or at least partially elastic, membrane.
- the membrane has membrane openings through which liquid flowing out of the hollow body can escape to the outside.
- the membrane opening of the membrane and the hollow body opening of the hollow body are arranged with respect to a radial direction of the cleaning roller on a common straight line.
- the openings of the membrane and of the hollow body lie one above the other, so that liquid flowing out of the hollow body can pass directly through the corresponding membrane opening to the outwardly facing surface of the membrane.
- the membrane opening and the hollow body opening do not lie exactly above one another, but for example both the membrane and the hollow body have a multiplicity of openings arranged irregularly on the circumference, for example in the manner of two perforated walls lying one above the other ,
- the membrane is arranged stationarily on the hollow body.
- the membrane can be fixed radially on the outside of the hollow body.
- different methods such as coating, injection molding, gluing or the like are suitable. Due to the stationary arrangement of the membrane on the hollow body constant flow paths for the liquid can be created, which remain even during rotation of the cleaning roller.
- the cleaning device according to the invention is not limited to wet cleaning devices, but may also be a dry cleaning device which is operated only in the event of cleaning the cleaning roller at a speed above the minimum speed. During rotation of the cleaning roller during a conventional surface treatment, the minimum speed is not exceeded, so that liquid can not escape from the hollow body.
- a dry cleaning can be carried out at a first, low speed without unwanted liquid leaking from the hollow body. Only when reaching or exceeding the minimum speed of the cleaning roller liquid is discharged from the liquid space.
- the defined minimum speed of the cleaning roller is at least 150 U / min up to 3,000 U / min.
- the specified minimum speed of 150 rpm stands out clearly from only accidental rotation of the cleaning roller during transport of the cleaning device. Likewise, this minimum speed also exceeds the speed of the cleaning roller at a mere displacement of the cleaning device over the surface to be cleaned.
- the specified speed range of 150 rpm to 3,000 rpm corresponds to the usual rotational speeds of the cleaning roller during a machining operation for cleaning a surface or for self-cleaning of the cleaning roller of adhering dirt.
- the required minimum speed for the discharge of liquid from the hollow body is determined by the aforementioned parameters, which influence the centrifugal force.
- Sponge body is sheathed. Additionally or alternatively, it can be provided that the hollow body and / or the sponge body is coated with a cleaning cloth, in particular a microfiber cloth.
- the surface of the cleaning roller is characterized by a sponge body and / or a rice cleaning cloth occupied.
- it may be a textile cleaning cloth in which the dirt dissolved by the surface to be cleaned is bound.
- the formation of the cleaning cloth as a microfiber cloth proves to be particularly advantageous. This is particularly advantageous in terms of the removal of dirt from the surface to be cleaned.
- the cleaning cloth or the sponge body is advantageously absorbent, so that a certain amount of liquid can be stored.
- a sponge body may be provided. This sponge body serves in particular as a buffer for the liquid. He sucks the liquid, which exits through the hollow body openings of the hollow body, and gives them to the cleaning cloth or the surface to be cleaned.

- the hollow body opening 5 is offset radially inward in the direction of the axis of rotation, whereby a chamber-like valve region results between the hollow body opening 5 and the surface of the hollow body 3, which is fluidically separated from the liquid space 4.
- a closure element 7 of the valve element 6 is arranged, which is displaceable in a closed position closing the hollow body opening 5 and in an opening position which releases the hollow body opening 5.
- a return element 8 is formed within the valve region between the surface of the hollow body 3 and the hollow body opening 5, which carries the closure element 7 at one of the hollow body opening 5 adjacent end region.
- the return element 8 is designed here as a helical spring, on one end face of which the plate-shaped closure element 7 is arranged.
- the return element 8 acts with its restoring force on the closure element 7 and presses it against the hollow body opening 5 bounding edge region of the hollow body 3.
- the hollow body opening 5 is closed fluid-tight, so that no liquid from the liquid space 4 can escape to the outside.

- the embodiment of Figure 6 could also be modified so that the hollow body 3 itself is formed as an elastic membrane 9 with corresponding membrane openings 10. The restoring force for reaching the closed position of the valve element 6 results, as in the case of FIG. 6, in the restoring force inherent in the material.
- All the variants of the invention shown have in common that no liquid can escape from the liquid chamber 4 when the cleaning device 1 is not in contact with a surface to be cleaned but is transported, for example.
- the speed of the cleaning roller 2 is zero, so that the minimum speed for opening the hollow body opening 5 or diaphragm opening 10 is not exceeded. If, however, the cleaning roller 2 rotates for a cleaning process at a speed greater than the minimum speed, the liquid can escape through the hollow body opening 5 or diaphragm opening 10 from the liquid space 4 and used for the cleaning process.
