Definitions
- the present invention relates to an actuating device for a cleaning device.
- the present invention relates to a cleaning device with an actuating device.
- the present invention relates to a cleaning system with two or more cleaning devices, which comprise a cleaning device of a first type and a cleaning device of a second type, which differs from the first type.
- the object of the present invention is to provide an actuating device for a cleaning device with the possibility of haptic feedback for an operator with a compact design.
- an actuating device for a cleaning device comprising a housing with an upper housing part facing an operator and a housing side wall, an electrical unit with at least one switching element arranged in the housing, the housing part comprising an actuating element arranged movably on the housing and having at least one actuating area or forms, which is in operative connection with the at least one switching element, and wherein the actuating device comprises at least one elastically deformable edge element, which extends along at least one continuous edge section in the circumferential direction of the housing between the actuating element and the Housing side wall extends and against the action of which the actuating element can be transferred from a basic position into at least one actuating position.
- a housing is provided with a housing side wall and a housing part which, when used as intended, faces an operator (here referred to as "above", although it is obvious to the person skilled in the art that this does not represent a restriction to an absolute reference system).
- the operator can transfer the operating element of the housing part from a basic position to at least one operating position, in particular by applying force from above to the operating area.
- the switching element that is directly or indirectly operatively connected to the actuating area is thereby actuated.
- the at least one edge element is elastically deformed and offers the operator haptic feedback on the actuation of the actuating device.
- haptic feedback can be provided by the at least one switching element.
- the at least one edge element is arranged in particular on an outer edge of the housing. In a plan view of the housing from above, this saves installation space, for example in the middle, which is available, for example, for positioning a display unit and/or at least one light-emitting element. A relatively large display unit and/or a generous illumination of the housing part from below can thereby preferably take place. As a result, there is the possibility of haptic feedback with a compact design of the actuating device.
- the at least one edge element acts as a damping element, against the effect of which the actuating element can be transferred into at least one actuating position.
- the at least one edge element forms a restoring element for the actuating element. It is favorable if the at least one edge element comprises or forms a sealing element which seals the housing between the housing part and the housing side wall. A separate sealing element can be saved as a result, which simplifies the design of the actuating device and enables a compact design. In particular, a seal against splashing water and/or dirt can be provided.
- the actuating element can, for example, be tilted on the housing for transfer from the basic position into the at least one actuating position.
- a movable mounting of the actuating element on the housing can also be provided, for example in a pivotable and/or displaceable manner.
- the at least one edge element is arranged between the at least one actuating region and the housing side wall with respect to the circumferential direction of the housing.
- the at least one actuating area is arranged on an outer edge of the actuating element.
- the force can be diverted downwards to the edge element to deform it.
- the edge element can be used to reset the actuating element on the actuating area.
- the actuation element as a whole, specifically the housing part as a whole, forms the actuation area. It is conceivable here that the switching element can be actuated, with the respective deformation of the at least one edge element, regardless of the position at which the user applies a downward force to the housing part. It is conceivable that the actuating device includes two or more actuating areas. For example, the two or more operating portions are arranged along equal angular intervals in the circumferential direction of the housing. The angular distance can, for example, relate to an axis defined by the housing.
- Two operating areas are provided, for example, which are arranged diametrically opposite one another with respect to an axis of the operating device.
- four operating areas can be provided, each distributed over an angular distance of 90°.
- the electrical unit comprises two or more switching elements, with the actuating element having two or more actuating areas, by the actuation of which the actuating element is transferred into a respective actuating position, wherein a respective actuating area is assigned a switching element, and wherein the at least one edge element is arranged on a respective edge section between the actuating element and the housing side wall, in particular between the respective actuating area and the housing side wall.
- the actuation areas are located in particular at different positions of the actuation element, for example as mentioned above.
- a respective switching element is actuated depending on which actuation area the operator actuates.
- the actuating device can be equipped with a plurality of functions via the two or more actuating areas and switching elements.
- At least one of the following functions can be initiated in the cleaning device via the actuation areas: switching on, switching off, calling up a menu, exiting a menu, moving within a menu, making a change to a setting within a menu. It can be favorable if an edge element is provided, which extends in the circumferential direction of the housing over two or more actuation areas. In this way, a structurally simpler configuration of the actuating device can be achieved. It can be provided that an edge element extends over all actuation areas.
- Two or more actuating areas can be arranged on the outer edge of the actuating element, with the outer edge preferably enclosing an inner area of the housing part, below which, for example, a display unit and/or at least one lighting element can be arranged.
- the housing part can be plate-shaped or disk-shaped, for example.
- a one-piece design of the housing part is conceivable, in which case, for example, the outer edge is connected in one piece (monolithically) to the inner region.
- an edge element and in particular exactly one edge element is provided, which extends along the entire circumference of the housing between the actuating element and the housing side wall.
- the at least one edge element is designed in the shape of a ring at least in sections on a ring section or is a ring.
- the ring section or the ring extends in particular along the entire outer circumference of the housing between the housing part and the housing side wall. It can be provided that the ring or the ring section is aligned with the housing side wall and/or with the housing part, at least in sections.
- the at least one edge element comprises a contact section that rests in a flange-like manner on the housing part. An operating force of the operator can be reliably received via the abutment section.
- the at least one edge element can preferably comprise an engagement section which overlaps an edge of the housing side wall facing the housing part and is in engagement with the housing side wall.
- this can ensure a reliable attachment of the at least one edge element to the housing side wall and, on the other hand, preferably enable sealing relative to the housing side wall.
- a groove is provided on the side wall of the housing, into which the engagement section engages.
- the engagement section can, for example, form a sealing section with a sealing bead, which engages in a corresponding groove of the housing side wall and seals in the installation position of the actuating device relative to the cleaning device receiving the actuating device.
- a seal relative to the cleaning device can be achieved via the sealing element, in particular the sealing bead, and entry of liquid and/or dirt into the cleaning device can be avoided.
- the edge element can comprise or form a deformation section with two or more sections which adjoin one another at an angle and which tilt relative to one another when the actuating element is actuated.
- An angle between adjacent sections can be changed by the operator applying force and the at least one edge element can be elastically deformed as a result.
- a support section in particular under the adjoining sections, is provided in particular, which is supported in the operating position of the operating element on an edge of the housing side wall facing the housing part. This gives, for example, the possibility of an adjustment path of the actuating element and thereby provide the operator with haptic feedback.
- the at least one edge element can be designed in the shape of a bellows, for example by means of the aforementioned sections, or can comprise or form a bellows.
- the at least one edge element consists of a foam material or comprises a foam material.
- foam material materials with a closed-cell and preferably waterproof structure (cellular rubber) or with a closed-cell outer skin (foam rubber) can be used as the foam material. All types of rubber are conceivable. Chloroprene rubber (CR) or ethylene-propylene-diene rubber (EPDM), for example, can prove to be advantageous.
- the compressive strength according to AST M D1056 (25%) can be 35 +/- KPa.

- the inner area can be translucent.
- the at least one edge element preferably comprises or forms an alignment section arranged between the housing part and a further housing part, with the display unit engaging in or passing through a through-opening of the alignment section. In this way, a correct relative position of the at least one edge element to the display unit can be ensured during assembly. For example, there is some play between the display unit and the edge of the through hole.
- At least one passage opening can be formed in the edge element, through which the light of at least one lighting element can pass to the upper housing part.
- a plurality of passage openings can be provided, which are assigned to a respective lighting element.
- the passage opening can be shaft-shaped or funnel-shaped and widen in the direction of the housing part.

- the further housing part preferably comprises or forms the housing side wall.
- the display unit can be connected to the housing part, in particular by gluing, for example via OCA bonding.
- a layer or a coating can be arranged on the side of the housing part facing away from the operator, which, for example, leaves out a transparency area for light emitted by the display unit in the inner area.
- the emitted light can be seen by the operator through the window-shaped transparency area, for example, and through the housing part, in order to capture visual information.
- the layer or coating preferably includes a light-absorbing area on the actuator. At least part of the spectrum can be absorbed by the light-absorbing region. This gives, for example, the possibility of designing the actuating element in a colored manner in a structurally simple manner.
- the housing part can preferably be designed to be transparent on the actuating element, as a result of which the color of the actuating element can be defined via the layer or coating.
- the layer or coating can be printed onto the housing part, for example.
- a housing part that is transparent overall is printed on the underside to form the light-absorbing area, with a transparency area being left out.
- the light-absorbing area comprises or forms, for example, an identification of the at least one actuation area.
- an identification of the at least one actuation area For example comes at least one pictogram or symbol used to identify the operating area, which can be understood intuitively by the operator.
- the transparency area can be smaller than a light-emitting section of the display unit, in particular an image display of the display unit, with a contour of the transparency area lying entirely within a contour of the light-emitting section.
- the somewhat window-shaped transparency area can be smaller than the light-emitting section. In this way, the operator only sees part of the display unit and the operator may not be able to see inside the housing. In this way, the visual information can be better perceived in the absence of distracting or disruptive influences.
- the light-absorbing area preferably completely surrounds the transparency area in a plan view of the housing part.
- the actuating device comprises at least one actuating member which is movably held on a holding part and via which the actuating element is in operative connection with the at least one switching element and which actuates the at least one switching element when the actuating element is transferred into the at least one actuating position.

- the at least one actuating member is preferably a lever member.
- the at least one switching element can, for example, be arranged laterally offset relative to the actuation area, based on a plan view of the actuation device.
- the use of a lever member has proven to be advantageous with regard to setting the force that can be applied to actuate the switching element.
- the lever member also proves to be advantageous for the acoustic and/or haptic perception of the actuation of the switching element. For example, a clicking noise, especially in the case of a micro switch or a micro button, can be easily heard by the user.
- the lever member may preferably be travel-enlarging. For example, a force path from the point of action of the actuation area on the lever member to the film hinge is smaller than a load path of an action area of the lever member on the switching element.
- the holding part can be, for example, a housing side wall part that at least partially forms a housing side wall.
- the at least one edge element comprises or forms an alignment section arranged between the housing part and the further housing part, with the at least one actuating member engaging positively in a through-opening of the alignment section or passing through it. This makes it possible to align the housing part relative to the edge element during assembly via the at least one actuating member. For example, there is some play between the actuator and the edge of the through hole.
- the display unit is glued to the housing part, as explained above, and that the at least one edge element is connected via the at least one actuating member and the through hole is oriented relative to the housing.
- the housing part can be aligned relative to the other housing part at the same time.

- Display unit 37 can be controlled by electrical unit 32, in particular initiated by electrical device 15.
- the display unit 37 includes an image display, in particular for the colored display of visual information in the form of color images.
- the display unit 37 is essentially planar and defines a plane transverse and in particular perpendicular to the axis 27.
- the housing side wall part 29 has a housing side wall 41 extending along the circumferential direction of the actuating device 20.
- the housing side wall 41 overlaps an edge 42 of the housing bottom part 30 and is sealed relative to it by a sealing element 43 .
- a further sealing element 44 is arranged on an outer circumference of the housing side wall 41 .
- the sealing element 44 seals relative to a wall 45 of the cleaning device 12, 22, 23 or 24, an opening 46 for receiving the actuating device 20 being formed in the wall 45. This is shown in FIG. 2 using the cleaning device 12 as an example.
- the housing side wall part 29 forms a holding part 47 for at least one actuating member 48.
- actuating members 48 are provided, each of which is assigned to one of the switching elements 36.
- a respective actuating member 48 is held on a segment of the holding part 47 which projects radially with respect to the axis 27 .

- the actuating member 48 forms a lever member.
- the distance between the projection 52 and the film hinge 50 is less than the distance between the free end and the film hinge 50.
- the lever member accordingly increases the displacement and reduces the force.
- lever member 53 proves to be advantageous for the perception of a clicking noise of the switching element 36.
- the actuating members 48 are arranged equidistantly from one another in the circumferential direction of the axis 27 and have an angular spacing of essentially 90° in each case. In terms of construction, the actuating members 48 are the same as the switching elements 36.
- the upper housing part 30 is designed in the form of a disk and is advantageously formed in one piece (monolithic).
- the housing part 30 is preferably made entirely of an optically transparent material which preferably allows light of the entire or essentially the entire optical spectrum to pass through.
- the housing part 30 forms an upper housing wall 56.
- the housing part 30 comprises an inner region 57 radially on the inside, which covers the display unit 37 at the top.
- the inner area 57 is surrounded by an actuating element 58 of the housing part 30 .
- the actuating element 58 is ring-shaped and forms an outer edge of the Housing part 30.
- the actuating element 58 and the inner region are connected to one another, in particular in one piece.
- the upper housing part 30 extends over the entire housing 26, defining a plane.
- the housing part 30 faces the operator and accordingly extends over the entire upper side of the housing 26.
- a layer 59 is arranged on the housing part 30 on the side facing away from the operator.
- the layer 59 is applied by printing the housing part 30 from the underside.
- the actuating element 58 is printed annularly along the entire circumference on a light-absorbing area which absorbs at least part of the visible spectrum. This allows the actuating element 58 to be colored from the underside (FIG. 4).
- an identification 61 on the actuating element 58 is ensured via the light-absorbing area.
- pictograms are printed on the actuating element 58, which will be discussed below.
- the layer 59 is printed in such a way that an uncoated transparency area 62 remains radially on the inside.
- the transparency area 62 enables the view through the inner area 57 to the display unit 37 .
- the display unit 37 is connected to the housing part 30 .
- the connection is made by gluing.
- FIGS. 7 to 10 show the corresponding adhesive layer, for example by OCA bonding.
- an optical coupling of the display unit 37 to the housing part 30 takes place via the adhesive bond.
- Light reflections between the housing part 30 and the display unit 37 can thereby be avoided.
- the housing part 30 bears against the housing side wall 41 and in particular rests on it via a damping element 67, which in the present case forms an edge element of the actuating device 20.
- the edge element 68 is ring-shaped in the present exemplary embodiment (see also the corresponding representation of the actuating device 110 according to FIGS. 11 to 14).
- the edge element 68 extends in the circumferential direction of the housing 26 along the entire outer circumference.
- the material thickness of the edge element 68 in the radial direction corresponds essentially to a material thickness of an edge 69 of the housing side wall 41 which faces the housing part 30 (FIGS. 5 and 6).
- the actuating element 58 rests, via the layer 59, along the entire circumferential direction on the edge element 68, which as a result rests with a contact section 70 in a flange-like manner on the housing part 30, as it were.
- the edge element 68 rests on the edge 69 via a support section 71 .
- the edge element 68 is preferably glued to the housing side wall 41 at the edge 69 . In a corresponding manner, gluing of the edge element 68 to the layer 59 on the actuating element 58 is preferably provided.
- the edge element 68 consists of a foam material. Reference is made at this point to the above statements on the material and/or the nature of the foam material.
- the edge element 68 can be elastically deformed by pressure on the actuating element 58 . Conversely, reshaping can take place in order to move the actuating element 58 back into an initial position. For this reason, the edge element 68 also forms a restoring element. In the present case, the edge element 68 also acts as a sealing element 72 for sealing the housing 26 between the housing part 30 and the housing side wall 41.
- the actuating element 58 has at least one actuating area 73 .
- Four actuation areas 73 are provided here.
- An actuating member 48 and a switching element 36 are assigned to each actuating region 73 .
- the four actuating regions 73 are arranged equidistantly from one another in the circumferential direction of the axis 27 and have an angular spacing of essentially 90° in each case. With respect to the axis 27, two diametrically opposed actuation areas 73 are provided.
- Each actuating area 73 is operatively connected to the switching element 36 assigned to it.
- the actuating element 58 assumes an actuating position. Accordingly, four different operating positions are provided in the present case.
- the actuating element 58 is tilted on the housing 26 (FIG. 6).
- the actuating device 20 is dimensioned in such a way that a relatively small tilting path of approximately 0.3 mm to 2.5 mm, preferably approximately 0.5 mm to 2 mm, is set.
- the edge element 68 is assigned jointly to the confirmation areas 73 in each case.
- edge element 68 Provision can also be made for the edge element 68 to extend over two or more actuation regions 73 in the circumferential direction of the housing 26 . This is particularly the case for the present edge element 68, which is ring-shaped and extends along the entire circumference.
- the edge element 68 When the actuation area is actuated (FIG. 6), the edge element 68 is deformed. In particular, an elastic deformation takes place. For the operator, haptic feedback about the actuation of the switching element 36 occurs at the actuation area 73 . In addition, provision can be made for the switching element 36 itself to provide haptic feedback.
- edge element 68 which has a damping and restoring effect, on the edge of the housing 26 enables a compact design of the actuating device 20, in that the inner area 57 for the positioning of the display unit 37 remains free.
- sealing effect in which the edge element 68 acts as a sealing element 72, proves to be advantageous for a compact design, since a separate seal can be saved.
- a structurally identical actuating device 20 is used in each case. Only a program stored in the memory unit 17 is different. The program is used to control the respective cleaning device 12, 22, 23 or 24, and its functions can be addressed. Furthermore, the visual information on the display unit 37 will vary depending on the program provided for the respective type of cleaning device 12, 22, 23 or 24.
- the program can, for example, be transmitted wirelessly from an external additional device 75 to the electrical device 15, which includes a communication element 76 for this purpose (FIG. 2).
- a cable connection to an external additional device 75 can be set up, for example via an electrical connection element 77 of the cleaning device 12 .
- the additional device 75 is a smartphone or a tablet computer, for example.
- the actuating areas 73 are also referred to below as actuating areas 73a to 73d.
- a respective operating area 73a to 73d is identified by a pictogram 78a to 78d which is printed over the light-absorbing area. This allows the operator to intuitively understand the function when operated on the operation portions 73a to 73d.
- the electrical device 15 and thus the cleaning device 12 can be switched on and off at the actuation area 73a.
- the actuation area 73a is located diametrically opposite the actuation area 73b.
- FIG. 7 shows a schematic representation of menu navigation in the program of memory unit 17 by means of actuating device 20.
- the user can switch on the device 15 by actuating the actuating area 73a and arrives at a main menu level 80 of the program. Subsequent to an optional greeting 81, the user can select submenus 81 within the main menu level 80 by actuating the actuating areas 73c and 73d. Entry into a respective menu level 83 of the selected submenu takes place by actuating the actuating area 73b.
- the operator can navigate within each menu level 83 by actuating the actuating areas 73c and 73d.
- a respective option 84 in a submenu 82 can be confirmed after selection by actuating the actuating area 73b, whereupon the main menu level 80 is called up again.
- the device 15 can, for example, be switched off at any time by actuating the actuating area 73a.
- the actuation area 73a is the actuation area 73 that is furthest away from the grip element 18 . Unintentional switching on or off can thus be largely avoided. With regard to access to the menus, it is advantageous if the actuating area 73b is arranged closer to the grip element 18 than the actuating area 73a and/or the actuating area 73 is arranged closest to the grip element 18 .
- An actuating device according to the invention shown in FIGS. 8, 8A, 9 and 10 and denoted by reference numeral 90 in a preferred embodiment, is structurally and functionally very similar to actuating device 20, but differs from it in particular in the design of edge element 68.
- the mechanism the actuation of the switching elements 36 via the actuating members 48 corresponds to that of the actuating device 20 .
- the actuating device 90 could be used instead of the actuating device 20 in the cleaning devices 12 or 22 to 24 .
- the edge element 68 is made of an elastomer material, for example.
- the edge element 68 in the case of the actuating device 90 is designed in the form of a ring in sections.
- the edge element 68 comprises a ring section 91 which corresponds in functional terms to the ring of the edge element 68 in the actuating device 20 .
- the edge element 68 comprises an alignment section 92.
- the ring section 91 includes the contact section 70 for flange-like contact on the underside of the housing part 30, via the layer 59. An adhesive bond can be provided here.
- the ring section 91 comprises an engagement section 93 and forms a deformation section 94 that can be deformed by the application of force.
- the edge element 68 overlaps the edge 69 on the outside, relative to the axis 27.
- the edge element 68 projects with the engagement section 93 beyond the edge 69 and includes a sealing bead 95 on the underside.
- the sealing bead 95 engages in a circumferential groove 96 on the outside of the housing side wall 41 and extends along the entire outer circumference of the housing 26.
- the engagement section acts as a sealing section and enables sealing relative to the wall 45.
- a separate sealing element such as the sealing element 44, can be omitted.
- the deforming portion 94 includes a radially outwardly extending portion 97 which is angled relative to the abutment portion 70 and the engagement portion 93 .
- the engagement section 93 adjoins the section 97 radially on the outside, and the contact section 70 adjoins the section 97 radially on the inside.
- the section 97 can be tilted relative to the contact section 70 and relative to the engagement section 93, changing the respective angle.
- the edge element 68 thus has a bellows-like configuration, with the height of the edge element 68 being reduced when a force is applied.
- the section 97 also acts as a support section 71 which, when actuated, comes to rest on the edge 69 at the top and thereby limits the tilting path of the housing part 30 (FIG. 10).
- the deformation of the ring section 91 provides the operator with haptic feedback. When deformed back, the ring section 91 acts as a restoring element for the housing part 30.
- the alignment section 92 is arranged below the layer 59 and is connected to the contact section 70 on the outside or forms this.
- a plane of the alignment section 92 is parallel to the plane of the housing part 30.
- Alignment portion 92 includes through openings 98 for projections 52 ( Figure 8). In the mounted state, the projections 52 reach through the through-openings 98 with some play. This facilitates the alignment of the edge element 68 relative to the housing side wall part 29 during assembly.
- the alignment section 92 includes a further through-opening 100 which is arranged below the inner region 57 .
- the display unit 37 can engage in the through opening 100 .
- the display unit 37 is first glued.
- the correct nominal orientation of this arrangement relative to the housing side wall part 29 is ensured by the engagement of the display unit 37 in the through opening 100 .
- a preferred embodiment of the actuating device according to the invention shown in FIGS. 12 to 14 is assigned the reference number 110.
- the actuating device 110 could be used instead of the actuating device 20 in the cleaning devices 12 or 22 to 24.
- the actuating device 110 has a simpler design. This is due in particular to the fact that no display unit 37 is provided. In addition, the actuating device 110 comprises only one switching element 36. The housing part 30 forms the actuating element 58 as a whole.
- the electrical unit 32 includes a lighting element 111, for example designed as an LED. Two or more light emitting elements 111 may be provided. The light-emitting element 111 is positioned centrally on the electrical unit 32 in relation to the axis 27 .
- the circuit board 35 forms the housing base 33.
- an annular, comparatively thin stiffening element (FIGS. 12 to 14) can be arranged between the edge element 68 and the housing side wall 41, which can be glued to the edge element 68 and the housing side wall 41. This can be used, for example, to reinforce the edge element 68 made of a foam material.
- the actuating member 48 is movably fixed via film hinges 50 to the holding part 47 formed by the housing side wall part 29 .
- the actuating member 48 is aligned concentrically with the axis 27 and is designed in the form of a funnel in sections.
- the actuating element 48 On the side facing away from the housing part 30 , the actuating element 48 has a central passage opening 112 for light that can be emitted by the lighting element 111 . In the direction of the housing part 30, the actuating member 48 widens in a funnel shape. Facing the housing part 30, the actuating member 48 in the present case comprises two projections 52 which bear against the housing part 30 on the underside (FIGS. 13 and 14).
- the switching element 36 is arranged on the electrical unit 32 on a side opposite the film hinges 50 in relation to the axis 27 .
- the actuating member 48 is thus also a lever member that increases travel and reduces force.
- the layer 59 is provided with a pictogram 78 on the transparency area 62, which symbolizes an on state when the luminous element 111 is activated or a switched off state when the luminous element 111 is not activated.
- edge element 68 is also a ring made of foam material, as in actuating device 20. Actuation in the direction of arrow 74 ( Figure 14) leads to elastic deformation of edge element 68 and, via projections 52, to tilting of actuating element 48 on the holding part 47 for actuating the switching element 36. A haptic feedback is provided by the edge element 68, which also acts as a restoring element for transferring the actuating element 58 back from the actuating position to the basic position.
- An actuating device according to the invention is constructed similarly to actuating device 110.
- the actuating device 120 likewise has only one switching element 36 and one lighting element 111 . Accordingly, only one actuating member 48 is provided in the present case, on which two projections 52 are arranged in the present case. The projections 52 can be removed from the actuating element 58 when this is subjected to an actuating force by the user be contacted, here initially being spaced therefrom ( Figure 16).
- the projections 52 bear against the layer 59 on the underside or directly against the housing wall 30 in the basic position.
- the layer 59 is not shown in FIGS. 15 and 16. It goes without saying that the actuating device 120 can be provided with a layer 59 .
- the actuating element 48 in the actuating device 120 is not designed in the shape of a funnel. However, as in embodiment 110, it has an essentially cylindrical edge.
- the actuating member 48 is held on the holding part 47 via a film hinge 50 .
- the edge element 68 is designed largely corresponding to the edge element 68 in the actuating device 90 with contact section 70 on the top side, support section 71, engagement section 93 and sealing bead 95. Due to the lack of a display unit, the edge element 68 has a central through-opening 122, which is circular in design and the actuator 48 surpasses in terms of the respective diameter.
- actuating device 120 can be used with any of the cleaning devices 12, 22, 23 or 24 described here.
- the actuating device 130 has many similarities with the actuating device 90, in particular with regard to the design of the housing 26 and the edge element 68 with contact section 70, support section 71, engagement section 93 and sealing bead 95 (FIG. 18).
- the display unit 37 is omitted. Instead, a plurality of light-emitting elements 111 are provided, in the present case five, although this number could also be different.
- Through openings 132 of the edge element 98 are assigned to the individual lighting elements 111 .
- the through-openings 132 are shaft-shaped in the present case and widen from the bottom upwards in the direction of the housing part 30. Walls of the through-openings 132 are preferably not transparent to the emitted light, so that at the top of the actuating element 58 only that section is illuminated which is illuminated by an active light-emitting element 111 is illuminated.
- the edge element 68 is therefore designed in particular for use with nine light-emitting elements 111, of which, as mentioned, only five are present on the electrical unit 32.
- the light-emitting elements 111 and through-openings 132 have a regular arrangement in an orthogonal grid.
- the layer 59 is not shown in the drawing for the actuating device 130 either; it could of course also be present.
- the projections 52 are shown arranged at a slight distance from the housing part 30 or the layer 59, so that there is a free travel during actuation. It goes without saying that the projections 52 could bear against the layer 59 on the underside or directly against the housing part 30 in the basic position. For the rest, especially with regard to the actuation, reference is made to the above statements.
