Description

[Technical Field]

[0001] The present invention relates to a handle device for a fluid cleaner, in particular a steam emitter, which is operated by a user and includes a casing including or forming a user handle element, a fluid line connectable or connected to the fluid cleaner and including or forming a fluid outlet for discharging fluid directly or through an attachment coupled or connectable to the handle device, and a user operating device carried by the casing and connectable or connected to the fluid cleaner via electrical control wiring.

[0002] The invention further relates to a fluid cleaning device, in particular a steam cleaning device, comprising a fluid cleaning device, in particular a steam emitter, and a handle device of the kind described above, connectable to or connected to the fluid cleaning device. [Background technology]

[0003] In such fluid cleaning devices, particularly steam cleaning devices, the handle device can be connected to a corresponding connection element (e.g., a bushing) on ​​the fluid cleaning machine via, for example, a plug-like connection element. A fluid cleaning machine is, of course, a cleaning machine that, in use, uses a fluid, e.g., water, to achieve a cleaning action. The fluid is supplied through a fluid pipe and is discharged directly through the handle device. Alternatively, an attachment for discharging the fluid can be connected to the handle device. In the case of a steam discharger, the attachment can be, for example, a hand nozzle, a floor nozzle with a handle, or a brush attachment for the fluid outlet.

[0004] A surface cleaning machine with task lighting, including a handle device, is described in US Pat. No. 5,623,999. Handheld irrigation devices for garden areas for discharging water are described, for example, in US Pat. No. 5,623,999 and US Pat. No. 5,623,999. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] EP 3 824 786 A1 [Patent Document 2] EP 2 828 003 D1 [Patent Document 3] DE 201 10 486 U1 Summary of the Invention [Problem to be solved by the invention]

[0006] SUMMARY OF THE INVENTION The object of the present invention is to provide a handle device of the type mentioned at the beginning and a fluid cleaning device comprising such a handle device, which has a structurally simple design. [Means for solving the problem]

[0007] This object is achieved by the invention in a handle device of the above kind in that the casing comprises a lower casing shell and a covering upper casing shell which are joined together via corresponding joining elements, a receiving opening surrounded by an edge is formed in the upper casing shell, and the fluid line extends partly within the casing between the operating device and the lower casing shell.

[0008] In the handle device according to the present invention, the casing comprises two shell-like components, namely a lower casing shell and an upper casing shell. The upper and lower casing shells abut against each other, for example along their edges forming a connecting element, thereby enclosing a storage space. For structural simplicity and ease of assembly, the operating device can be inserted into the upper casing shell, in particular by fitting it into a receiving opening located at the top of the upper casing shell. The fluid lines can be placed in the lower casing shell. The fluid lines partially run under the operating device between the operating device and the lower casing shell. The electrical control wiring can be led out of the casing alone or, for example, together with the fluid lines, inside a hose line or the like. The casing shells can be joined together, thereby closing the casing.

[0009] Position and orientation descriptions such as "below", "above", "below" and "above" relate here to the conventional use of the handle device, i.e. when the user grasps the handle element, in particular from above, and the control device is on the upper side of the casing facing the user, for example for operation with the thumb. For example, the control device may include an activatable optical display unit, which can be located on the upper side of the casing to ensure good visibility to the user.

[0010] The handle device according to the invention has the advantage that the sealing of an electrically configured operating device, which is preferably self-sealing, can be achieved in a structurally simple manner: by inserting the operating device into the receiving opening, a significantly smaller area to be sealed remains above the handle device compared to conventional handle devices using left and right housing shells.

[0011] A user can control the fluid washer through electrical control wiring. For example, the user can control the release of fluid by controlling a valve element within the fluid washer through an operating device. For example, the amount of fluid released can be adjusted through the operating device.

[0012] For ease of handling, the operating device may be configured with, for example, a menu guide, and may in particular include an activatable display unit, which may output status information about the fluid cleaner to the user.

[0013] The lower housing shell is formed, for example, in the shape of a bathtub with rounded inner walls.

[0014] The upper housing shell is formed, for example, in the form of a cover with a rounded inner wall.

[0015] Advantageously, the lower casing shell can be free of receiving openings for the operating device, which prevents dirt from entering the casing from below.

[0016] The operating device can preferably only be operated by the user from above.

[0017] The operating device can be arranged, for example, above the joining element of the upper casing shell, preferably above the edge.

[0018] It is advantageous if the handle device comprises a dividing element arranged between an upper casing shell and a lower casing shell, between which a first storage space for the operating device is formed and between which a second storage space for the fluid piping is formed. The advantage of at least partially dividing the casing interior space into a first storage space and a second storage space is that, for example, it is desirable to be able to seal the operating device as an electrical component from the fluid piping as a fluid component.

[0019] Accordingly, it may be advantageous if the dividing element seals the first receiving space from the second receiving space, for example by sealingly abutting the upper casing shell and / or the lower casing shell.

[0020] The dividing element may for example be at least partially plate-shaped.

[0021] For example, the dividing element is configured as a dividing wall between the receiving spaces.

[0022] The dividing element can be, for example, connected to the upper and / or lower casing shell, in particular by force and / or form fitting.

[0023] On the other hand, the upper and lower casing shells may be joined together, for example by a force fit and / or a form fit.

[0024] It is conceivable that the connecting elements connecting the casing shells together can simultaneously be used to adjust and / or fasten the dividing elements.

[0025] Advantageously, the dividing element can comprise a plurality of guide elements between which the fluid line is guided in the second receiving space, for example, the guide elements can be provided with (especially formed with) protrusions between which the fluid line is held in the correct target position in the second receiving space.

[0026] The handle device can include an electrical device in the first storage space below the handle element, the electrical device in particular including a circuit board electrically connected to the operating device. In this way, for example, the storage space below the handle element can be utilized, allowing the handle device to have a compact construction. In a preferred embodiment, the first storage space is sealed off from the second storage space via the dividing element as described above.

[0027] The dividing element may form a support element for the handling device resting on the dividing element. The handling device rests on the dividing element, for example, at the edge of the floor wall or bottom side. The support element can hold the handling device, for example, in a predetermined target position. The handling device is arranged, for example, by a form fit, between the edge of the receiving opening and the dividing element.

[0028] The handle device may include, for example, a coupling element for coupling with an accessory. The coupling element is, for example, held movably, in particular orientably, on the upper casing shell or the dividing element, on the opposite side of the operating device from the handle element. The coupling element may, for example, have a coupling member at its free end, which extends through a passage opening in the upper casing shell. The coupling member may, for example, be an engaging member and / or a pushing member, which can engage and / or push into the accessory. The coupling element is, for example, arranged above the dividing element, and the passage opening is arranged on the upper side of the casing. An operating element for the user may be provided.

[0029] In an advantageous embodiment, the operating device and the upper casing shell abut against each other via corresponding abutment elements, which ensure that the operating device is in the correct target position relative to the upper casing shell. Corresponding abutment elements are arranged, for example, on the outer periphery of the operating device and on the edge of the receiving opening. For example, the operating device can be supported from below on one or more abutment elements of the upper casing shell.

[0030] In preferred embodiments of the invention, the handling device may be, for example, disc-shaped and / or substantially cylindrical in shape, e.g., the handling device may be substantially "puck" or "pillbox" shaped with a substantially cylindrical outer contour, the height of which is significantly smaller than the diameter.

[0031] The receiving opening can be, for example, round, in particular in the case of the previously described embodiments of the operating device, and can in particular be circularly formed on the upper side of the upper housing shell, and the operating device can, for example, comprise a lid element on its upper side that is received in the receiving opening by form-fitting, and which lid element covers, for example, an activatable display unit of the operating device.

[0032] Alternatively or additionally, the operating device can, for example, rest against the edge of the receiving opening from the side of the first receiving space via an upper support element, in particular on the lid element, which is embodied on the lid element, for example, in the form of a circumferential shoulder, and rests against the upper edge of the receiving opening from below.

[0033] The operating device is preferably dustproof and / or waterproof, in particular conforming to the protection class IPX4.

[0034] In a preferred embodiment, the handle device may include a first portion on the proximal side that includes or forms the handle element, and a second portion on the distal side that includes the outlet, preferably to which an attachment can be coupled, preferably by bayonet connection. "Proximally" and "distally" herein relate to the normal use of the handle device, i.e., when a user grasps the handle element from the proximal side and fluid is released to the distal side.

[0035] In an advantageous embodiment, the first and second parts each extend linearly and are oriented at an angle to one another, and the operating device is located at the transition where the first and second parts meet. Practice has shown that arranging the parts at an angle to one another is advantageous for handling.

[0036] The angle (here, the larger of the two angles between the two portions) is, for example, about 130 to 170 degrees, preferably about 140 to 160 degrees, for example, about 150 degrees.

[0037] The operating device may include, for example, a disk-shaped, planar lid element on its upper side that covers a display unit of the operating device, the surface normal of the lid element forming an angle of less than about 20 degrees, preferably less than about 10 degrees, with respect to the bisector of the angle between the first and second portions, such that information on the display unit is easily visible to the user.

[0038] For a compact and easy-to-handle construction, the handle device can have a continuously widening profile from the first section to the transition section and / or a continuously narrowing profile from the transition section to the second section, which can, for example, have a circular profile when viewed from above (especially if the operating device is substantially cylindrical).

[0039] As mentioned at the outset, the present invention also relates to a fluid cleaning device.

[0040] A fluid cleaning device of the type described above according to the present invention includes a handle device of the type described above connectable or connected to said fluid cleaner.

[0041] The advantages already achieved in connection with the description of the handle device according to the invention can also be achieved with the fluid cleaning device according to the invention. Advantageous embodiments of the fluid cleaning device according to the invention are produced by advantageous embodiments of the handle device according to the invention, see the previous description.

[0042] The fluid cleaning device is in particular a steam cleaning device, including a steam washer.

[0043] The fluid cleaning device may include at least one attachment, and preferably a plurality of attachments.

[0044] The following description of preferred embodiments of the present invention is provided in conjunction with the drawings to provide a more detailed explanation of the present invention. [Brief explanation of the drawings]

[0045] [Figure 1] 1A and 1B are schematic diagrams showing preferred embodiments of a fluid cleaning device according to the present invention, including a handle device according to the present invention; [Figure 2] FIG. [Figure 3] FIG. [Figure 4] FIG. 4 is another perspective view of the handle device shown in exploded view. [Figure 5] FIG. 3 is a perspective vertical cross-sectional view of the handle device shown in detail. DETAILED DESCRIPTION OF THE INVENTION

[0046] 1 of the drawings shows a preferred embodiment of a fluid cleaning apparatus according to the present invention, generally designated 100, configured here as a steam cleaning apparatus for cleaning surfaces. The apparatus includes a fluid cleaning device 102 configured as a steam cleaner and a preferred embodiment of a handle apparatus according to the present invention, designated 104.

[0047] The fluid washer includes a container 106 for a fluid, particularly water, which is connected to an outlet 110 via a pipe 108.

[0048] Fluid washer 102 further includes an electrical control 112 electrically coupled to connection 114 .

[0049] The fluid washer 102 includes an outlet 110 and a connecting element 116 , such as a bushing, that receives the connecting portion 114 .

[0050] The handle device 104 is operated by a user and is here removably connected to the fluid cleaner 102 via a preferably flexible hose line 118. For this purpose, a connecting element 120 (in particular a plug-like element) is arranged on the hose line 118, which can be mated with the connecting element 116. The connecting element 120 receives an electrical connection 122 at the end of an electrical control line 124 and an inlet 126 at the end of a fluid line 128. Within the line 108, a valve element 130 is switched under the control of the control device 112 in order to selectively open or close the line 108.

[0051] The control wiring 128 may comprise, for example, a multi-pole cable, such as a flat cable, and preferably allows two-way communication between the handle device 104 and the fluid cleaner 102 .

[0052] The fluid cleaning device 100 further includes a plurality of attachments 132 that can be removably coupled to the handle device 104 and through which the cleaning fluid is released. The attachments 132 may include, for example, a hand nozzle, a floor nozzle with a handle, or a brush attachment, although this selection is merely exemplary and non-limiting.

[0053] 2-4, the handle device 104 includes an elongated casing 134. The casing 134 includes a lower casing shell 136. The lower casing shell 136 is tub-shaped with a rounded inner wall 138.

[0054] The casing 134 further includes an upper casing shell 140. The upper casing shell 140 is cover-like with a rounded inner wall 142.

[0055] The casing shells 136, 140 can be joined together such that an edge 144 of the lower casing shell 136 and an edge 146 of the upper casing shell 140 abut against each other. The edges 144, 146 are joining elements 148. Along the edges 144, 146, the casing 134 is waterproof and substantially dustproof.

[0056] The upper casing shell 140 and the lower casing shell 136 can be connected to one another by means of, for example, a press fit and / or a form fit, whereby, for example, connecting elements are pressed or engaged together. Screwing and / or gluing are also contemplated.

[0057] 2, casing 134 includes a first portion 150 disposed proximally of handle device 104. First portion 150 defines a handle element 152 that can be grasped by a user (not shown). First portion 150 extends substantially linearly and defines an axis 154.

[0058] Casing 134 further includes a proximally disposed second portion 156 that defines a connection region 158 to which attachment component 132 can be selectively connected. Second portion 156 extends substantially linearly and defines an axis 160.

[0059] A transition section 162 is located between the sections 150, 156, and both sections 150, 156 are bounded by it from opposite regions.

[0060] The portions 150, 156 are oriented relative to one another at an angle 164. The angle 164 between the axes 154, 160 is here approximately 150 degrees, which practice has shown makes the handle device 104 easier for the user to handle.

[0061] When viewed from the top, the casing 134 has a continuously increasing profile from the first portion 150 to the transition portion 162. At the transition portion, the casing has a rounded, particularly circular, profile when viewed from the top. Furthermore, the profile of the casing 134 continuously narrows from the transition portion 162 to the second portion 156.

[0062] As a result, the casing 134 and thus the handle device 104 have a compact structural form.

[0063] The handle device 104 has a receiving opening 166 on the upper side of the upper casing shell 140. The receiving opening 166 is located in the transition section 162. A rim 168 surrounds the receiving opening 166. The upper side of the rim 168 is rounded, in particular circular. This rim extends downward toward the lower casing shell 136, here spanning approximately half the extension of the upper casing shell 140. The rim 168 is preferably closed circumferentially.

[0064] On the underside, facing the lower casing shell 136, the edge 168 is provided with at least one abutment element 170 (FIG. 5).

[0065] To operate the fluid cleaning device 100, and in particular the fluid cleaner 102, the handle device 104 includes an operating device 172. The operating device 172 is electrically configured and electrically connected to the controller 112 via electrical control wiring 124. This allows, for example, the valve element 130 to be opened so that cleaning fluid can be delivered to and released from the handle device 104. Conversely, the valve element 130 can be closed, which stops the release of cleaning fluid.

[0066] The control device 172 is configured cylindrically in this case, which is disk-shaped. Approximately, the control device 172 has the shape of a "puck" or "pillbox" with a cylindrical profile (FIG. 4).

[0067] The operating device 172 is fitted into the upper casing shell 140 from below. Abutment elements 178 are arranged on the outer periphery 174 of the casing 176 of the operating device 172. The abutment elements 178 are radial protrusions that can abut against the at least one abutment element 170 from below. This allows the operating device 172 to be positioned in a predetermined target position relative to the upper casing shell 140.

[0068] The handling device 172 has a lid element 180 on its upper side. The lid element, in this case, is plate-shaped and defines a plane with a surface normal 182 of the lid element 180. Angle 184 between surface normal 182 and a bisector 186 of angle 164 is in this case less than about 10 degrees.

[0069] Below the lid element 180, the operating device 172 has an actuable display unit 188, which in the present case has a number of light-emitting elements 190. Alternatively or additionally, for example, an actuable picture display can be provided.

[0070] Orienting the control device 172 as described herein allows the information on the display unit 188 to be better perceived by the user.

[0071] The operating device 172 has a support element 192 on its upper side, which in this case consists of the cover element 180 and is embodied in the form of a shoulder. Via the support element 192, the operating device 172 rests against the underside of the upper edge 168 of the receiving opening 166, which also ensures that the operating device 172 is in the correct target position.

[0072] The handle device 104 includes a dividing element 194 within the casing 134. This dividing element is here a dividing wall 196 disposed between the casing shells 136, 140. The dividing wall 196 extends from approximately the center of the first portion 150 to the center of the second portion 156.

[0073] The dividing wall divides the space within the casing 134 into a first storage space 198 formed between the dividing wall 196 and the upper casing shell 140 and a second storage space 200 formed between the dividing wall 196 and the lower casing shell 136.

[0074] The operating device 172 is arranged in the first receiving space 198 above the dividing wall 196. The dividing wall serves as a support element for the operating device 172 from below, thereby ensuring that the device is in the desired position.

[0075] The hose line 118 is proximally connected to the casing 134 at the first portion 150. The fluid line 128 extends within the casing 134 at the second receiving space 200 and terminates at the fluid outlet distally at the second portion 156.

[0076] During assembly, for example, the fluid lines 128 may be placed within the lower casing shell 136 .

[0077] The dividing wall 196 is connected to the upper casing shell 140 here by a force fit and a form fit, and abuts against the inside of the upper casing shell 140, in particular by means of a sealing edge element 204. In this way, in particular the first receiving space 198 is sealed from the second receiving space 200, and thus electrical components in the form of the operating device 172 are sealed from fluid components in the form of the fluid lines 128 that run partially below the operating device 172 between it and the lower casing shell 136.

[0078] For further connection, the dividing wall 196 is provided with a receiver 206, here in the form of a blind hole, into which a projection 208, here in the form of a plug, on the upper casing shell 140 is pushed in.

[0079] The handle device 104 further includes an electrical device 210 electrically connected to the operating device 172. It here comprises a circuit board 212. The circuit board 212 is arranged below the handle element 152 in the first receiving space 198 and is therefore likewise protected with respect to the second receiving space 200 by the sealing of the dividing wall 196.

[0080] The control wiring 124 can be guided through an opening 214 in an intermediate wall 216 in the upper casing shell 140. A sealing element can be arranged in the opening 214 to close the gap. The control wiring 124 enters the hose line 118 at the proximal first portion 150.

[0081] Here, guide elements 218 are arranged on the dividing wall 196, which are preferably formed on the integral dividing wall 196. The guide elements 218 are formed as protrusions, between which the fluid lines 128 extend, so that the fluid lines 128 are held in the correct target position.

[0082] The already mentioned connection area 158 is here in the form of a connecting pipe. The attachment 132 can be removably coupled to the handle device 104 by plugging.

[0083] For this purpose, a coupling element 220 is further provided. In this example, the coupling element 220 is held on the upper casing shell 140 via a protrusion 208 in a directionally movable manner. The free end of the coupling element 220 forms a coupling member 222 (here, an engagement member) arranged outside the casing 134. For this purpose, the coupling element 220 penetrates into a passage opening 224 on the second part 156.

[0084] Additionally, the coupling element 220 extends into the passage opening 226 with an operating element 228 .

[0085] In the coupled state, the coupling members 222 are engaged with the corresponding coupling members of the attachment 132. By pressing the operating element 228, the coupling elements 220 are turned downward, thereby disengaging the coupling members. [Explanation of symbols]
