EP4144273A1 - Add-on component for a floor cleaning device and floor cleaning device - Google Patents

Abstract

The invention relates to an additional component for a floor cleaning device with a suction nozzle (3) with a suction mouth, the additional component having a carrier body (8) with a frame (11) with at least one flat cleaning area facing a floor surface to be cleaned with a drying and/or cleaning covering (9), wherein the carrier body (8) can be placed on the floor surface to be cleaned in such a way that the floor cleaning device can be placed on the additional component. The known additional components are either not suitable for brushing and/or suction devices or are complicated to install. This improves the invention in that the frame (11) has a passage opening through which the suction mouth is in active contact with the floor surface to be cleaned when installed as intended, despite the presence of the additional component, and which has at least one edge element on two opposite sides of the passage opening with at least a drying and/or cleaning covering (9), the carrier body (8) having holding edges which protrude upwards when the frame (11) is resting on the floor surface and which are designed in such a way that they use edges or edges of the suction nozzle (3) as abutment edges engage behind and lateral guides are provided which are able to hold the additional component transversely to the movement of the suction nozzle (3).

Description

The invention relates to an additional component for a floor cleaning device designed as a brushing wet/dry vacuum cleaner, in particular for a wet/dry vacuum cleaner, according to the preamble of claim 1 and a floor cleaning device according to the preamble of claim 13.

The additional component is intended for floor cleaning devices that have a suction nozzle with a motor-driven cleaning brush arranged therein, which rotates about an axis of rotation parallel to the floor. In addition to the brush, these devices have a suction unit arranged in a device housing, the suction nozzle which is flow-connected to the suction unit and a dirty liquid tank for receiving dirty liquid which has been separated from a sucked-in suction material flow. The dirty liquid tank is in flow connection with the suction unit via an air outlet of a dirty liquid tank connection and preferably has a float for monitoring the fill level and/or for reducing the power consumption or for switching off the suction unit.

A generic additional component that is provided for a designed as a vacuum cleaner with steam cleaning function floor cleaning device is from EP 1 027 855 A2 known. This floor cleaning device is designed as a combined suction and steam cleaning device. It has a suction nozzle which, like a conventional vacuum cleaner, has a suction slot which is surrounded by a rotating brush with bristles which can be adjusted against the floor. Outlet ports for steam are provided behind the ensemble slot. The additional component is attached to the suction nozzle in order to be able to wipe the floor like a mop. For this purpose, the suction/brush housing of the suction nozzle has projections onto which corresponding receptacles of the additional component can be pushed in order to latch the additional component to the underside of the suction nozzle.

A similar solution for the suction nozzle of a classic canister vacuum cleaner, in which an additional component in the form of a dimensionally stable cleaning pad can be attached to the outside of the suction nozzle via holding hooks, is from US2007/0033767A1 known.

The two solutions described above both have the disadvantage that on the one hand they can only cover the underside of the suction/brush housing of the suction nozzle and thus provide an improved wiping function, but are not able to cover vertical edge surfaces of the floor, in particular skirting boards, to clean. A further disadvantage is that the attachment of the additional component to the suction nozzle has to be released by the user by manually releasing the latching connection. Furthermore, they have to be plugged onto the suction/brush housing of the suction nozzle with great effort and restrict the suction function in the case of the EP 1 027 855 A2 by covering the slotted nozzle in certain areas.

Furthermore, from the U.S. 2009/0094780 A1 a similar device is known with which the edge area, especially when cleaning is to be carried out in the vicinity of baseboards, cannot be cleaned with sufficient thoroughness. This is due to the fact that the brush is mounted on the side, so that there is inevitably a section in the area of the suction nozzle that cannot be covered by the brush rotating about a horizontal axis.

The suction nozzles of other floor cleaning devices, for example the suction nozzles of vacuum cleaners, also have similar disadvantages. An additional component for the suction nozzle of a vacuum cleaner is from JP2009119025 A2 known. This additional component consists of individual pads that are clamped into slots on the underside of the suction nozzle between the suction inlets. The disadvantage of this additional component is that, on the one hand, it can only cover a small area between the individual suction openings and, on the other hand, receiving slots must be provided on the side of the suction nozzle, which are adapted to the locking connection of the additional component. Furthermore, the user has to clip the relatively small components to the underside of the suction nozzle by hand in a complicated process.

From the CN211243149 U In turn, an attachment for the suction nozzle of a wet/dry cleaner is known, which is clamped to the suction nozzle of the device via a clamping bracket, with corresponding fastening means on the suction nozzle for this purpose available. The additional component itself consists of a plate that lies on the floor behind the suction nozzle and is dragged behind it by the suction nozzle. The disadvantage of this known additional component is that the attachment must be present on the side of the suction nozzle and that the mechanical connection via the clamping bracket has to be produced in a very complex manner for the user. For this reason, it is not possible to quickly attach and remove the additional component. A similar solution is shown in EP3595501 A1 or the EP1600092 A2 . Other solutions with fixed to the suction nozzle or the suction / brush housing of the suction nozzle additional components are from EP3207850 A1 , the CN301997329S , the JP2003135348 A2 and the JP3070795 U known.

The US2009077761A again shows a sweepings pick-up for a mechanical sweeping device that has a rotating brush, with side brushes being provided on the underside of the brush housing, but fixed and not removable, sideways of the rotating brush. Although this solution also allows the side areas to be cleaned, it requires the brush housing to be configured in the factory.

All known additional components thus have the disadvantage that the brush housing of the floor nozzle must have fastening means provided at the factory, via which the additional component is attached to the floor nozzle. Solutions where this is not necessary are shown in the JP2003265374 A2 and the JP2006212201A2 . In both of these configurations of an additional component, the additional component is attached to the floor nozzle via Velcro strips which are firmly attached to a cleaning pad. Although this solution can be easily retrofitted, it has the disadvantage that the user has to attach the Velcro fasteners in a comparatively complicated manner. It is also not possible to easily pick up the additional component if required.

The object of the invention is therefore to create an additional component for expanding the cleaning effect and functionality of a floor cleaning device that is easy to assemble and disassemble. A further object is to create a floor cleaning device which is designed in particular as a handle device and which can easily be expanded with an additional component.

According to the invention, these objects are achieved by an additional component according to claim 1 and a floor cleaning device according to claim 15 .

The new additional component is characterized in particular by the fact that the user can simply place the suction nozzle onto the additional component from above, which, by inserting the suction nozzle from above, connects to the suction nozzle to such an extent that it can fulfill its essential function. The additional component itself consists of a carrier body, which is connected to a frame or is designed as a frame, to which at least one drying and/or cleaning covering can be or is fastened in such a way that it faces the floor surface to be cleaned or a side surface is.

This essential function of the additional component is, on the one hand, that the rotating brush can continue to maintain the necessary ground contact, particularly in connection with brushing devices. Furthermore, the function is that the additional component should be moved by the user reciprocally moved forwards and backwards suction nozzle. It is not important that the additional component is absolutely firmly connected to the suction nozzle. It can certainly be a connection with play, as long as there is a passage window for the contact of the brush or the suction mouth with the floor.

According to the invention, it is now recognized that it is sufficient to provide abutment edges that enable the movement of the additional component together with the suction nozzle to be coupled in the essential directions and are designed in such a way that when a suction nozzle is inserted from obliquely above or vertically from above, corresponding edges of the Suction nozzle to be reached from behind. In addition, side guides are provided which prevent the additional component from slipping off the suction nozzle to the side. The edges to be gripped from behind can be any housing edges or projections. Of course, the side guides in particular can also clamp the suction/brush housing of the suction nozzle laterally.

The pairs of abutment edges responsible for the movement of the additional component in the forward or backward direction can also be provided within the suction/brush housing. For example, the additional component can project vertically or obliquely upwards, be cylindrical or have a different cross-section have shaped domes or flat wall areas that engage in areas of the suction nozzle underside. These areas can be, for example, the opening of the suction nozzle or the opening in which a brush is mounted.

A major advantage of the solution according to the invention is that the user can easily connect the suction device to the additional component and also remove it again without having to bend down or without having to engage or release snap-in connections. In a preferred embodiment, therefore, insertion is provided from above without the additional component latching onto the suction/brush housing of the suction nozzle or into another component of the cleaning appliance. This has the particular advantage that the user can detach the additional component from the suction nozzle by simply lifting the device and can continue to use the device without the additional component.

The additional component preferably has at least one drying area or cleaning area or a combination of both functions. The task of the additional component is either to provide an additional cleaning effect, especially in areas where, for example, the suction effect is too low or a brush cannot be active due to special design features, and in combination with wet/dry vacuum cleaners, if necessary, also to improve drying guarantee. Drying can be improved simply by sucking up liquid residues behind the suction mouth. Alternatively, the liquid tension of drops can also be influenced by mechanical action, so that instead of a drop-shaped film of water behind the suction mouth, there is a smooth liquid film that can dry without leaving any water stains.

The cleaning pad can be made of any material. All kinds of sponges, felt coverings, leather and leather imitations, textile fabrics and knitted fabrics and plush are available here. Ideally, the cleaning pad is naturally absorbent so that it can absorb residues of cleaning liquid. Long-pile materials whose fiber lengths are, for example, 5 mm, preferably 8 mm or even more than 10 mm, are suitable for tearing up water drops. Even longer pile threads, for example with a length of 0.04 m or 0.1 m, can be used. The cleaning pad can also laterally over the carrier body and the frame protrude, so that when it comes into contact with a side surface, in particular a skirting board or other surface that protrudes at right angles or at an angle from the floor to be cleaned, it is dammed up or pushed up, resulting in a laterally protruding cleaning surface.

On the one hand, the additional component can take on cleaning tasks to the right and left of the suction nozzle or the brush. In a further embodiment, the additional component has edge elements which protrude laterally upwards and which can be used, for example, for cleaning baseboards and other vertical surfaces. These edge elements can be foldably connected to the carrier body of the additional component. Preferably, this will then be designed in such a way that the edge elements either form a large-area cleaning element for the floor in one plane with the underside of the additional component or, folded up by 90°, represent an additional edge cleaning element.

Another task can be the mechanical cleaning of both the edge areas and the area behind a brush or a suction mouth. In particular when there is a risk that liquid residues or also dust residues will not be sucked up, it can be useful to absorb or at least remove such disruptive cleaning residues via the additional component. As a continuous covering, the drying and/or cleaning covering can cover the entire underside and possibly also the lateral cleaning elements. It can also be integrally connected to the carrier body of the additional component. For example, the drying and/or cleaning coating can be applied to a carrier body made of plastic as part of a shaping process, for example by flocking.

Alternatively, the drying and/or cleaning covering can also be fastened to the frame of the carrier body using Velcro fasteners, clamp fasteners or similar fasteners. Furthermore, it can be designed as a pocket that can be pushed onto the carrier body of the additional component or into which the frame can be pushed. Finally, several drying and/or cleaning layers can also be used, which can also have different properties. In the area behind the brush or the suction mouth, for example, a higher suction effect may be desired. Here the drying and/or cleaning covering have a higher absorbency. The area on the sides, on the other hand, may possibly have a dirt-dissolving effect. Any area provided in front of the brush can also be designed as a pre-cleaning element, so that a more scratching effect can be preferred here, for example. Ultimately, this depends on the area of application of the respective cleaning device.

If easy release by simply removing the suction nozzle from the carrier body is not desired, but instead a firmer connection between the additional component and the suction/brush housing of the suction nozzle is desired, for example to be able to lift the device from step to step when cleaning stairs without that the additional component detaches, snap-in connections can also be provided which automatically lock into the carrier body of the additional component when the suction/brush housing of the suction nozzle is inserted. For this purpose, a pair of latching edges is provided at suitable positions.

For this purpose, a particularly preferred embodiment uses a front area of the carrier body that protrudes vertically upwards and is angled in the direction of the rear area, under which a front edge of the suction nozzle can be pushed. This then forms the front latch. In this case, the rear catch is realized on the back of the suction nozzle. This can preferably also include a latching edge, for example, which is provided on a foldable handle of the cleaning device. When inserting the suction nozzle into the carrier body of the additional component, this connection is then automatically established in which spring-loaded latching elements engage.

The inclination of the handle of the cleaning device can then be used to release the snap-in connection mentioned above. For example, moving the handle to an extreme position or raising the handle to a position perpendicular to the suction nozzle as a storage position can move the latching edges away from one another and thus release the latching connection. This has the advantage that the user also does not have to bend down to remove the additional component from the suction nozzle. Alternatively, of course, there is also the possibility that the user presses his foot on a suitable area of the additional component and can thus press the spring-mounted locking elements apart. Same can also in case a frictional connection between the additional component and the suction nozzle as an alternative to the snap-in connection.

a further embodiment of an additional component with a floor nozzle in a three-dimensional side view.

In figure 1 an additional component according to the invention is shown in connection with a floor cleaning device designed as a wet/dry vacuum cleaner 1 . The Figures 2 to 10 show the same additional component in different views.

The wet/dry vacuum cleaner 1 is designed here as a so-called handle device, i.e. it has a handle 5 with a handle 4 at the upper end, which the user can use to switch on and guide the wet/dry vacuum cleaner 1. In the lower area of the handle 5, a device housing 2 is provided, in which a dirty liquid tank 7 is arranged in a removable manner. The wet/dry vacuum cleaner 1 shown here is not just a pure vacuum cleaner, but is designed as a combination device for cleaning with a brush and subsequent vacuuming of hard surfaces. For the cleaning function, it has a fresh water tank 6, in which fresh water or cleaning liquid is stored for supply to an application device, which is arranged in addition to the lower suction nozzle 3 in the front functional area.

An essential feature of the present invention is the additional component that can be arranged or is arranged under the suction nozzle 3 . The additional component consists of a carrier body 8 which is essentially formed by a frame 11 . This frame 11 has a flat underside that does not interfere with the cleaning function of the floor nozzle and the brush arranged therein.

For connection to the floor nozzle 3, the frame 11 is provided with retaining edges that protrude upwards. These are, for example, the fastening means 10, which can be seen in the left and right area of the frame 11. These are two wall areas with different shapes, for example, which protrude from bottom to top. They engage in areas of the underside of the suction nozzle 3 and thus ensure that the additional component is dragged along when the suction nozzle 3 is moved back and forth.

In this exemplary embodiment, the frame 11 of the additional component is in turn U-shaped, so that a passage opening remains free in the front area, through which the suction mouth or a brush of the suction nozzle 3 can be in operative contact with the floor to be cleaned. Alternatively, of course, the frame 11 can also be designed as a peripheral, closed frame 11, which then has a window as a passage opening at a suitable point.

The frame 11 has cleaning elements 9 directed vertically upwards on its sides. These side surfaces are used to create vertical surfaces of the room, For example, to be able to clean skirting boards or edges of furniture in one go. For example, this is in the bottom view shown in figure 3 is shown to see. Here you can see that the brush of the cleaning device has to keep a certain distance to the edge areas due to the design. These are now also cleaned by the additional component according to the invention via lower cleaning pads. How from the Figures 1 and 2 and especially from the Figures 9 and 10 can be seen, not only the horizontal floor area in the corners and edges of the room is cleaned, but also vertical surfaces, such as baseboards, can be cleaned by the vertical surfaces of the cleaning elements 9 .

That in the Figures 1 to 10 The additional component shown is guided exclusively via the holding elements 10, which cause both lateral guidance and a dragging movement in the main directions of movement of the suction nozzle 3 (back and forth). The particular advantage of this solution is that the user can couple the additional component simply by placing the suction nozzle 3 on top of it. Additional fastening movements or measures are not required. Conversely, this also allows the additional component to be detached from the suction nozzle 3 again simply by lifting the cleaning device with the suction nozzle 3 .

In the exemplary embodiment shown, the drying and/or cleaning covering is shown schematically as a thin covering which is glued onto the frame 11 and the edge elements 9 . This is only to be seen as an example, alternatively other fastenings or pocket-shaped coverings can also be used. Furthermore, it is of course possible to manufacture the additional carrier completely from the drying and/or cleaning material from a correspondingly dimensionally stable felt or another cleaning material. This can also be used as a dry-cleaning covering, especially in connection with vacuum cleaners, and have an antistatic effect for absorbing dust, for example.

The shape of the frame 11 is best from the Figures 4 and 5 to recognize. In figure 3 It can also be seen that an area with a width A ₁ in the edge area can also be covered by the additional component. Furthermore, the area between the outer end of the suction nozzle 3 and the outer edge of the brush with a width A ₂ is also by the additional component, here in the rear behind the brush, covered. In this way, the component allows to significantly increase the cleaning areas and avoids leaving uncleaned areas.

In figure 11 a further embodiment of the additional component is shown. This additional component has a ramp-shaped configuration of the frame 11 . The user can simply move the cleaning device with the suction nozzle 3 backwards onto the additional component. So that this does not slip, he can fix it with his foot. By driving onto the ramp, the additional component is locked laterally with the suction/brush housing 2 of the suction nozzle 3. To release this configuration, the user can step onto the rear area of the additional component and simply move the cleaning device forward.

In this configuration, too, no further precautions are necessary on the suction/brush housing 2 of the suction nozzle 3 in order to securely connect the additional component to the suction nozzle 3 . Instead of the ramp onto which the suction nozzle 3 is driven, a transverse area of the additional component that is shifted correspondingly further to the rear can of course also be provided. In this case, the entire suction nozzle 3 up to the rollers would then be arranged in the passage opening. In order to be able to exert appropriate pressure on the side surfaces, in this case the suction nozzle 3 can stand up slightly on the side arms protruding forward, so that the suction nozzle 3 also presses the front part of the frame 11 onto the floor surface to be cleaned with its weight.

Even if all the functions of the components mentioned in combination certainly define an advantageous overall object, they can also be used independently of one another. An independent protection for the individual features of the subclaims and the embodiments described here according to Figures 1 to 11 is therefore reserved.
