Description

Base station for connecting a cleaning device and method for mounting a base station to a wall

Technical Field

The invention relates to a base station for connecting a cleaning device and to a method for mounting a base station on a wall.

Background

A base station in the sense of the present invention is a constructive arrangement, preferably a stationary arrangement, for the electrical and/or fluid connection of a cleaning device, in particular in order to (electrically) load (charge) the cleaning device and/or to empty or suck up a collecting container of the cleaning device.

A cleaning appliance in the sense of the present invention is preferably a handheld guided vacuum cleaner, such as in particular a mobile floor vacuum cleaner, a trunk vacuum cleaner or a stick or handle vacuum cleaner, or a (partially) autonomous or self-propelled or self-flying vacuum cleaning robot (hereinafter referred to as suction robot).

However, a cleaning device in the sense of the present invention may also refer to other installations for cleaning and/or maintaining surfaces, in particular floors. For example, a floor wiping device or floor wiping robot, a polishing device or polishing robot, a window wiping device or window wiping robot or a mowing device or mowing robot may in principle also be understood as a cleaning device in the sense of the present invention.

EP 3033982 a1 discloses a base station for cleaning and/or emptying a hand-held cleaner, wherein the base station can be connected with an optional adapter module in order to connect a suction robot to the base station in addition to the hand-held cleaner.

Disclosure of Invention

The object of the invention is to provide an improved base station, preferably for a plurality of cleaning devices, in which a simple, convenient and/or rapid assembly on a wall is achieved or supported.

The object of the invention is achieved by a base station for connecting a cleaning appliance according to the invention or a method for mounting a base station to a wall according to the invention.

The base station proposed is designed for connecting at least one (preferably a plurality of) cleaning devices, in particular fluidically and/or electrically, and comprises a bottom module and a top module which is arranged above the bottom module in the mounted state of the base station, preferably wherein the top module and the bottom module are connected to one another, in particular electrically and/or fluidically, in particular pneumatically, via a connecting section.

The bottom module and/or the top module are designed for electrically and/or fluidly connecting the cleaning device (respectively). For this purpose, the bottom module and/or the top module comprise a fluid (in particular pneumatic) interface and/or an electrical interface for the cleaning device.

Preferably, the first cleaning device, in particular a self-propelled cleaning device, such as a suction robot, is electrically and/or fluidly connectable to the bottom module, and the second cleaning device, in particular a handheld guided cleaning device, such as a handheld vacuum cleaner, is electrically and/or fluidly connectable to the top module.

According to a first aspect of the invention, the bottom module may be moved or adjusted in relation to the top module in at least two degrees of freedom, for example in order to displace or tilt the bottom module and the top module in relation to each other. In this way it is possible to adapt the base station to the (current) spatial/structural conditions during the assembly process. In particular, it is thereby possible to align or orient the bottom module toward the floor, and/or to position the bottom module at a desired height and/or orientation, in an adjusted condition relative to the top module, in order to ensure a safe coupling with the cleaning device or the suction robot. A particularly simple, flexible and rapid assembly is thus possible with the proposed base station even under different constructional conditions.

According to a further aspect of the invention, which can also be realized independently, the installation height of the base station can be set by moving or adjusting the bottom module and the top module relative to one another. In this way, the structural height of the base station can be adapted both to the spatial/structural conditions and to the body dimensions of the user, in order to make comfortable operation of the base station possible.

Preferably, the bottom module can be adjusted relative to the top module in one (particularly preferably two or three) rotational degree of freedom and/or in one (particularly preferably two or three) translational degree of freedom. Thus, it is preferred that the bottom module is deflectable relative to the top module about one or more axes of rotation and/or displaceable relative to the top module along one or more axes of direction.

In order to enable relative movement between the bottom module and the top module, the base station is preferably provided with an at least partially flexible or articulated connecting portion which is arranged between the bottom module and the top module or connects the bottom module movably or hingedly to the top module.

The connection portion may comprise or be formed by one or more springs, bellows, universal joints or elastic materials such as rubber blocks to achieve the desired flexibility or movability.

In the proposed assembly method, the top module of the base station is preferably fixed to the wall independently of the bottom module, in particular screwed thereon and/or glued thereon, and the bottom module is (subsequently) aligned or directed towards the ground with adjustment relative to the top module, in particular such that the bottom module lies flat on the ground.

Additionally or alternatively, the structural height of the base station is adjusted during the assembly process, in particular by moving the bottom module and the top module relative to each other or by changing the distance from the bottom module to the top module. In this way, corresponding advantages are achieved and are therefore not repeated.

In principle, the aspects and features of the invention described above and those of the invention which result from the following description can be realized independently of one another or in any combination.

The electrical interface 30B of the second cleaning device 30 is preferably formed by one or more electrical contacts or, in particular for wireless energy transmission, by one or more coils, wherein the electrical contacts or coils are arranged on the outside of the second cleaning device 30.

An electrical connection between the base station 10 or the top module 50 and the second cleaning device 30 or its battery 30A is established by a wireless or wired coupling of the electrical interface 30B of the second cleaning device 30 and the electrical interface 50E of the top module 50. It is particularly preferred that the electrical connection is established autonomously when the second cleaning device 30 is suspended from the base station 10 or the top module 50 or is mechanically coupled to the base station 10 or the top module 50.

In the connection position shown in fig. 1, the second cleaning appliance 30 is electrically connected to the base station 10 or the roof module 50, in particular to the electrical interface 50E, so that the second cleaning appliance 30 or the battery 30A of the second cleaning appliance 30 is electrically connected to the base station 10 or the roof module 50 and the battery 30A can be charged by means of the base station 10.

The electrical interface 50E is preferably supplied with current by the first power supply apparatus 10A. Optionally, the top module 50 is (also) equipped with a second or own power supply device and/or a second or own current interface.

There may also be solutions which are particularly suitable for use in external areas, in which the system 1 or the base station 10 is designed as a self-sufficient or battery-powered system. For example, the system 1 or the base station 10 can comprise one or more solar modules and/or accumulators or be designed as a photovoltaic-independent power supply system.

As already described in connection with the electrical connection between the base station 10 and the second cleaning device 30, when the second cleaning device 30 is suspended in the base station 10 or in the top module 50, an optional fluid connection is preferably also established autonomously between the base station 10 or the top module 50 and the second cleaning device 30 or its collecting container 30C.

The receptacle 50G of the top module 50 is preferably larger than the collecting receptacle 30C of the second cleaning apparatus 30, in particular twice or three times larger, so that the entire contents of the collecting receptacle 30C of the second cleaning apparatus 30 can be accommodated by the receptacle 50G of the top module 50.

Particularly preferably, the volume of the container 50G is greater than the total volume of the collecting container 20C of the first cleaning device 20 and the collecting container 30C of the second cleaning device 30. Therefore, it is preferable that the entire contents of the collection container 20C of the first cleaning apparatus 20 and the collection container 30C of the second cleaning apparatus 30 can be accommodated in the container 50G of the top module 50.

The volume of the container 50G of the top module 50 is preferably greater than 1l or 1.5l, particularly preferably greater than 2l or 3 l.

With the aid of the working machine 50J it is possible to transport fluid from the second cleaning device 30 or its collecting container 30C to the base station 10 or its container 50G or vice versa and/or to change the pressure in the container 50G or filter 50H.

In the embodiment shown, the work machine 50J is designed as a fan and/or is designed to reduce the pressure in the container 50G, thereby transporting suction from the collection container 30C of the second cleaning device 30 into the container 50G.

The base station 10 or the top module 50 is preferably equipped with a flap 10D in order to open, empty the base station 10, in particular the top module 50 or the container 50G and/or the bottom module 40 or the container 40G, and/or to replace the

50H or 40H.

In the embodiment shown, the flap 10D is designed as a detachable or deflectable cover. However, it is also possible to equip the front face 50C with a flip 10D, for example.

By means of the fluid connection between the base station 10 and the

cleaning device

20, 30, it is possible to fill or empty, in particular suck empty, the

cleaning device

20, 30 in the connection location.

For example, the suction can be sucked out of the collecting container 20C of the first cleaning device 20 via the fluid connection 40F of the bottom module 40 and/or the suction can be sucked out of the collecting container 30C of the second cleaning device 30 via the fluid connection 50F of the top module 50 and transferred into the container 40G of the bottom module 40 or into the container 50G of the top module 50. In this way, manual emptying of the

cleaning device

20, 30 can be dispensed with.

However, it is also possible to convey or pump a liquid, such as a cleaning agent, via the fluid interface 40F of the bottom module 40 and/or via the fluid interface 50F of the top module 50 to the collection container 20C of the first cleaning device 20 or to the collection container 30C of the second cleaning device 30. In this case, the working

machine

40J or 50J is preferably designed as a pump (respectively).

The bottom module 40 and the top module 50 are preferably fluidly connected to each other, or can be fluidly connected to each other, in particular to fluidly connect the first cleaning device 20 with the top module 50 or the second cleaning device 30 with the bottom module 40, or to (also) empty or fill the first cleaning device 20 with the top module 50.

It is particularly preferred that the fluid connection 40F of the bottom module 40 and the fluid connection 50F of the top module 50 are fluidically connected to a common container or a common work machine, in particular to the container 40G or the work machine 40J of the bottom module 40 or the container 50G or the work machine 50J of the top module 50, in order to empty or fill the

cleaning device

20, 30 by means of the common container and/or the common work machine.

In the configuration shown in fig. 1, both cleaning

devices

20, 30 are fluidly connected to the top module 50 or its container 50G and/or its working machine 50J, so that the contents of the collecting container 20C of the first cleaning device 20 and the contents of the collecting container 30C of the second cleaning device 30 can both be transported into the container 50G by means of the (common) working machine 50J. Alternatively, both cleaning

devices

20, 30 may be fluidly connected to the base module 40 or its container 40G and/or its work machine 40J.

The container 50G or the filter 50H has an inlet, wherein in the embodiment shown both cleaning

devices

20, 30 or the

fluidic interfaces

40F, 50F thereof are connected to the inlet fluidically or via corresponding lines.

Preferably, the base station 10 comprises optional blocking means 10E, such as a blocking shutter or a valve, in order to control the volume flow and/or the direction of the volume flow. In particular, by means of the locking device 10E, the first cleaning device 20 or the fluid connection 40F, or the second cleaning device 30 or the fluid connection 50F can be selectively fluidically connected to the container 50G or the filter 50H.

The base station 10 preferably comprises a control device 10F which controls the (electrical) loading (charging), emptying and/or filling of the

cleaning devices

20, 30. For this purpose, the control device 10F is preferably electrically connected to the (first) electrical interface 40E, the (second) electrical interface 50E, the power supply device 10A, the (first) work machine 40J, the (second) work machine 50J and/or the locking device 10E.

The base station 10 preferably includes a fluid conduit 60B that fluidly connects the bottom module 40 (particularly the fluid interface 40F) with the top module 50 (particularly the container 50G).

The fluid conduit 60B is preferably designed to be flexible or bendable, in particular such that relative movement between the bottom module 40 and the top module 50 is possible or does not damage the fluid connection between the bottom module 40 and the top module 50.

As already explained, the system 1 or the base station 10 is preferably constructed in a modular manner and can be expanded by one or more modules.

By modularizing the system 1 or the base station 10, it is possible to connect an existing module (e.g. the bottom module 40) to another module (e.g. the top module 50) in order to be able to connect another

cleaning device

20, 30 to the base station 10 and/or in order to add additional functions to the base station 10, such as a suction function. In addition, one or more functions may be assumed by the added modules.

In the example shown, although both

modules

40, 50 may be used for suction and charging of the

cleaning devices

20, 30, preferably one or more functions are performed by either the bottom module 40 or the top module 50.

As already explained, the bottom module 40 and the top module 50 are (axially) connected to each other by a connecting portion 60.

The connecting portion 60 is preferably designed to enable a mechanical, fluidic and/or electrical connection between the bottom module 40 and the top module 50.

For this purpose, the connecting part 60 preferably comprises a particularly flexible or displaceable/articulated connecting shaft or connecting channel 60C, in which the electrical lines 60A and/or the fluid lines 60B are guided.

The connecting section 60 is connected to the bottom module 40 and/or the top module 50, in particular by snap connections, preferably form-fit, force-fit and/or material-fit.

The connecting section 60 preferably comprises a bottom element 60D, a top element 60E and/or at least one intermediate or compensating element 60F, wherein preferably the bottom element 60D is connected to the bottom module 40, in particular to the upper section 40D, in a form-fitting, force-fitting and/or material-fitting manner, and/or the top element 60E is connected to the top module 50, in particular to the housing 50A, in a form-fitting, force-fitting and/or material-fitting manner.

The compensating element 60F is preferably arranged between the bottom element 60D and the top element 60E and/or is designed to be at least partially flexible or movable/hinged, as will be explained in more detail below.

The bottom element 60D and the top element 60E are preferably rigid and can be designed, for example, as a plate, which is connected to the bottom module 40 or the top module 50, in particular by means of hooks, positively, non-positively and/or materially.

Preferably, bottom element 60D and top element 60E each include an opening (not shown) through which electrical leads 60A and/or fluid conduit 60B are directed.

The connecting passage 60C may be formed by a separate member such as a hose extending through the bottom element 60D and the top element 60E. However, it is equally possible to form or laterally delimit the connecting channel 60 by the compensating element 60F.

As already explained, the connecting section 60 (in particular the compensating element 60F) is designed to be at least partially flexible or elastic and/or movable or articulated in order to in particular enable a relative movement between the bottom module 40 and the top module 50.

The connecting portion 60 may comprise, for example, a block made of an elastic material (fig. 1), a bellows (fig. 2), a spring or a spring washer (fig. 3) or a universal joint, in particular as a compensating element 60F.

In a preferred embodiment (not shown), the connecting portion 60 is covered, or the base station 10 has a cover/baffle covering the connecting portion 60. The cover/baffle may for example be formed by a downwardly projecting slat of the top module 50, which at least partially overlaps the bottom module 40, in particular the upper portion 40D.

The bottom module 40 is movable in at least one degree of freedom, in particular in a plurality of degrees of freedom, relative to the top module 50.

As indicated by corresponding arrows in fig. 2, the bottom module 40 is preferably movable or displaceable relative to the top module 50 in at least one (in particular two or three) translational degree of freedom T1, T2, T3 and/or movable or rotatable relative to the top module 50 in at least one (in particular two or three) rotational degree of freedom R1, R2, R3.

In the following, for the purpose of describing the movability, the three directional or movement axes X, Y and Z shown in fig. 2 are used as cartesian coordinate systems.

The base station 10 has a main axis a, wherein the main axis a is at least substantially centered or extends perpendicularly through the base station 10. The main axis a is in particular the longitudinal axis of the preferably elongated base station 10.

The direction axis X is a horizontal axis and is elongated at least substantially parallel to the wall 2 and the ground 3 and/or at least substantially orthogonal to the main axis a of the base station 10.

The direction axis Y is a vertical or normal axis and is elongated at least substantially parallel to the wall 2 and/or at least substantially orthogonal to the floor 3. Particularly preferably, the direction axis Y corresponds to the main axis a of the base station 10.

The direction axis Z is a horizontal axis and is elongated at least substantially parallel to the ground 3 and/or at least substantially orthogonal to the main axis a of the wall 2 and/or the base station 10.

Preferably, bottom module 40 is movable along and/or rotatable/pivotable about directional axis X, directional axis Y and/or directional axis Z relative to top module 50.

By moving the bottom module 40 or the top module 50 along the direction axis X (translational degree of freedom T1) and/or along the direction axis Z (translational degree of freedom T3), the bottom module 40 and the top module 50 can be offset from each other, or a parallel offset can be produced between the bottom module 40 and the top module 50. In this way, the distance of the bottom module 40 and the top module 50 relative to the wall 2 can be set, for example, independently of each other.

By moving the bottom module 40 or the top module 50 along the direction axis Y (translational degree of freedom T2), the distance between the bottom module 40 and the top module 50 can be changed, and thus the structural height H of the base station 10 can be changed.

By moving or pivoting the bottom module 40 relative to the top module 50 about the direction axis X (rotational degree of freedom R1), the direction axis Y (rotational degree of freedom R2) and/or the direction axis Z (rotational degree of freedom R3), the bottom module 40 and the top module 50 can be tilted relative to one another or an angular offset of preferably more than 5 ° or 10 ° can be produced between the bottom module 40 and the top module 50. In this way, it is possible, for example, to make it possible or easy to fit the base station 10 to an inclined wall 2 or to compensate for deviations from a 90 ° angle between the wall 2 and the floor 3.

This installation situation is shown in fig. 3, where the angle between the wall 2 and the floor 3 is greater than 90 °.

Fig. 3 shows the base station 10 in an installed state according to another embodiment, wherein the compensating element 60F is formed by a spring, in particular a helical spring.

In the present case, the connecting section 60 has a plurality of (here four) compensating elements 60F. However, it is also possible to use only one, preferably centrally arranged, spring as the compensating element 60F. In this case, the compensation element 60F can form a connecting channel 60C and an electrical line 60A or a fluid line 60B can be guided in the compensation element 60F.

As already explained, the base station 10 is preferably mounted to the wall 2 such that the wall 2 at least partially or completely receives the weight of the base station 10 or the top module 50. It is particularly preferred that only the weight or a part of the weight of the bottom module 40 presses on the ground 3.

When assembling the base station 10, in particular the top module 50, is preferably screwed (screwed) and/or glued indirectly or directly to the wall 2.

Particularly preferably, the top module 50 is fixed to the wall 2 independently/separately from the bottom module 40.

Preferably, the system 1 or the base station 10 comprises fixing means 10G for fixing the base station 10, in particular for fixing the top module 50, preferably wherein the fixing means 10G are screwed and/or glued to the wall 2. The fixture 10G may be formed, for example, by a hook or the like, on which the base station 10 (particularly the top module 50) is suspended. In the embodiment shown, the fixture 10G engages into a void on the back side 50B of the top module 50.

During assembly, it is possible to vary the structural height H of the base station 10 by a relative movement of the bottom module 40 and the top module 50 with respect to one another or along the direction axis Y and/or by compressing or stretching the connecting portion 60 (in particular the compensating element 60F). In this way, it is possible to adapt the base station 10 to the body dimensions of the user to ensure a comfortable connection of the second cleaning device 30 with the base station 10.

Due to the connection section 60, the base station 10 can be adapted to different structural conditions. In the example shown in fig. 3, the angle between the wall 2 and the floor 3 is greater than 90 °, so that in a rigid embodiment (not shown) of the base station 10 either the distance between the base station 10 and the wall 2 along the main axis a varies or the base part 40B does not lie flat on the floor 3.

In order to align or orient the bottom module 40 toward the ground 3 even if the top module 50 has been secured, in particular so that the base portion 40B lies flat on the ground 3, the bottom module 40 may be adjusted or deflected relative to the top module 50 about one or more directional axes X, Y and/or Z.

In particular, as indicated in fig. 3, it is possible to create an angular offset between the bottom module 40 and the top module 50.

When aligning the base module 40, the connecting part 60, in particular the compensating element 60F, is locally compressed or stretched to produce the desired angular offset, or to push the base module 40 in the direction of the wall 2.

The bottom module 40 is preferably manually aligned with the top module 50. However, it is also possible for the bottom module 40 to align the fixed top module 50 due to its own weight or to be self-supporting, so that it lies flat against the wall 2 or the floor 3.

If the desired orientation of the bottom module 40 is set, the bottom module 40 can be fixed to the wall 2, in particular screwed thereto, in order to determine the position or orientation of the bottom module 40 relative to the top module 50.

However, the base station 10 (in particular the bottom module 40 and/or the top module 50) may also be equipped with a locking device 10H in order to determine or lock the position or orientation of the bottom module 40 relative to the top module 50. The locking device 10H shown in fig. 3 comprises a plurality of clamping or tensioning devices which interact mechanically with corresponding webs.

Due to the flexibility or pliability, the electrical leads 60A, the fluid conduits 60B, and/or the connecting channels 60C may be adapted for such adjustment without affecting the electrical or fluid connection between the bottom module 40 and the top module 50.

Optionally, the base portion 40B of the bottom module 40 is (also) designed to be deflectable relative to the back plate 40C or the upper portion 40D, as shown in fig. 3. In the present case, the bottom module 40 is equipped with a hinge 40K that pivotably connects the base portion 40B to the back panel 40C. Additionally or alternatively, the back plate 40C may be designed to be at least partially flexible. In this way, the base station 10 can be better adapted to different structural conditions at the time of assembly.

According to a further aspect of the invention, which can also be realized independently, the structural height H of the base station 10 can be set/set, in particular during the assembly process, by moving or adjusting the bottom module 40 and the top module 50 relative to one another. In this way, the structural height H of the base station 10 can be adapted both to the spatial/structural conditions and to the body dimensions of the user, in order to make comfortable operation of the base station 10 possible.

The various aspects and features of the invention may be implemented independently, but may also be implemented in any combination and/or order.
