Description

 Suction nozzle and Hartflächenabsauggerät

The present invention relates to a suction nozzle, in particular for a vacuum extraction device comprising a portable Hartflächenabsauggerät, which suction nozzle has a suction port, which is followed by a suction, the suction port remote from the suction port end connected to the suction or connected to the suction nozzle at least one flexible wiper lip extending along the suction opening and having a scraper lip edge facing away from the suction opening and extending in the direction thereof, and a support lip extending parallel or substantially parallel thereto with a support lip edge facing away from the suction opening and extending in the direction thereof or are trained.

Furthermore, the present invention relates to a Hartflächenabsauggerät, in particular portable, with a suction device and a suction nozzle cooperating with the suction nozzle, which has a suction port, which is followed by a suction channel, which is connected to its suction port remote from the suction port end connected to the suction device or connected.

Suction nozzles and Hartflächenabsauggeräte of the type described above, which are used for example as a window sucker, are known. Slices wetted with cleaning fluid, in particular, can be cleaned quickly and easily with such devices.

One problem with window vacs available on the market, however, is to draw vertical surfaces down to the ground with a single continuous vertical movement of the window vacuum from top to bottom. It has hitherto been necessary, as in the case of cleaning floor-deep letters with a portable hard-surface extraction device known, for example, from WO 2009/086891 A1, to suck the surface to be cleaned near the bottom by a horizontal movement of the Hartflächenabsauggeräts parallel to the surface with a substantially vertically aligned suction.

It is therefore an object of the present invention to improve a suction nozzle and a Hartflächenabsauggerät of the type described above so that in particular a handling of the same in the soil-deep cleaning of vertical hard surfaces is improved.

This object is achieved in a suction nozzle of the type described above according to the invention that the support lip on a pointing away from the wiper lip support lips outside, which defines a support lip outer surface, a support lip profile with a plurality of arranged on the support lips outside or formed supporting lip profile elements and that the support lip profile elements of the Support lips have outer side facing support lip profile element surfaces that form part of the support lip outer surface.

In the known Hartflächenabsauggeräten the wiper lip and the support lip are relatively narrow, so each have a width across the Abstreiflippenkante or to the support lip edge, which allows only a finite deformation of the wiper lip and the support lip. Thereby, an angle between the hard surface suction device and a hard surface to be cleaned can be varied only in a small range to obtain the function of suction. At an acute angle, a contact pressure of the Abziehlippe may be insufficient and at too large an angle, the support lip is usually no longer on the hard surface. For optimum function of the hard surface suction device, it is particularly advantageous if the pressure force is within a relatively small range, because if the contact force is too high, the support lip is pressed flat against the hard surface. Then it is no longer possible that water can pass through the suction opening into the suction channel and can be sucked off. The proposed supporting lip profile provides a remedy here, because, in particular, in the case of essentially flat on the hard Surface adjacent support lip, it is either directly through the Stützlippenpro- filelemente or between them possible to pass liquid to the suction port of the suction nozzle and thus in a suction of the same. However, this constructive change causes an overall improved function of the suction device, namely with a large tolerance range in the pressing or pressing force over a large angular range of an angle of attack between the suction nozzle and the hard surface to be sucked off. For the user, this in particular results in forgiving operation. In addition, this also supports the function of Hartflächenabsauggeräts when tilting a vertical hard surface towards the lower end, which allows in particular floor to ceiling windows, the continuous cleaning of a vertical hard surface from the top to the very bottom in one go. The support lip profile makes it possible, in particular, for a cleaning liquid moistening the hard surface to be cleaned to reach the suction opening more quickly and also for a rapid movement of the suction nozzle over the hard surface to be prevented from being pushed away.

It is advantageous if the support lip profile elements are designed in the form of profile depressions and / or profile elevations. Profile depressions make it possible, in particular, to form liquid channels when the support lip rests substantially flat against the hard surface to be cleaned. The profile recesses then allow the passing of the hard surface wetting cleaning liquid to the suction port, when the suction nozzle is pulled over the hard surface. Particularly with very small angles of attack between the support lip and the hard surface, the profile depressions improve the function of the suction device as a whole. Instead of providing profile depressions, alternatively or additionally, profile elevations can also be provided. Between two adjacent profile elevations, a fluid channel can thus be formed, through which cleaning liquid, which wets the hard surface, when moving the suction nozzle over the hard surface in the area between the support lip and the wiper lip and thus can reach the suction opening. Conveniently, the support lip profile elements go over tangent-like manner into a support lip outer surface region of the support lip outer surface that is not defined by the support lip profile. In particular, tangential discontinuous means that an edge is formed between the support lip profile elements and the support lip outer surface region, specifically an outer edge in the case of a profile recess and an inner edge in the case of a profile elevation. If the support lip outer surface is flat or continuously curved, the profile elevations form, for example, recesses projecting from the support lip outer surface and profile depressions in the support lip outer surface. The faces of the profile elevations and profile depressions facing away from the support lip, together with the support lip outer surface area, form the entire support lip outer surface.

It is advantageous if the support lip profile elements extend in a direction which extends transversely, in particular perpendicular, to the support lip edge. In this way, cleaning fluid can reach virtually the shortest path to the suction port, when the suction nozzle is pulled with the support lip over the hard surface. Usually, the suction nozzle is pulled in a direction over the hard surface, which extends transversely, in particular perpendicularly, to the wiper lip edge or to the support lip edge. In such a handling of the Hartflächenabsauggeräts then run the support lip profile elements parallel to the peeling, ie parallel to the direction defined by the movement of the suction nozzle on the hard surface.

Preferably, the support lip edge extends along a straight line or a plane. This makes it possible, in particular, for the supporting lip edge to lie against a flat hard surface along its entire length.

The support lip can be produced in a particularly simple manner if the support lip outer surface in a basic position is flat or substantially planar or curved, in particular tangentially continuous. According to a further preferred embodiment of the invention can be provided that a support lip profile-free support lip outer surface region of the support lip outer surface in a basic position of the support lip in which it is undeformed, flat or substantially flat. Such a support lip can be produced in a simple manner, for example, spray on a Saudüsengehäuse.

Furthermore, it may be advantageous if the support lip profile elements define a common Stützlippenprofilelement- edge with the support lip outer surface region, which is substantially U-shaped and open towards the support lip edge facing out. In particular, the support lip profile element edge can define a tangential transition between the support lip profile element and the support lip outer surface region. U-shaped may in particular mean that a contour defined by the supporting lip profile element edge is tangentially curved. Alternatively, one or two tangent-like points may be provided on the contour.

A particularly favorable fluid flow results when the support lip profile element edge is parabolic or substantially parabolic.

In order to improve the flow of cleaning fluid in the region of the support lip profile towards the suction opening, it is advantageous if a support lip profile element width of the support lip profile element increases starting from a support lip edge facing away from the support lip edge to the support lip edge. In other words, this means in particular that the support lip profile element starting from the support lip profile element, for example, has a width of zero or a minimum width, which then tangentenstetig or sections may also increase tangentenunstetig to the support lip edge.

Preferably, the support lip profile element width increases in response to a distance from the support lip profile element end. In particular, the support lipsprofilelementbreite so specified as a function of the distance and are optimized fluidically.

It can further be provided that the support lip has two lateral edges extending transversely to the support lip edge, and that a support lip profile element width and / or a surface defined by the support lip profile element edge increases with decreasing spacing of the support lip profile element from one of the two side edges. In particular, the profile elements can thus always become somewhat larger toward an edge of the suction nozzle, that is to say in the direction of the side edges, in order to compensate for a suction power usually decreasing toward the side edges of the suction nozzle.

Furthermore, it can be advantageous if a contour of the support lip profile elements is defined by a function which depends on the distance from the support lip profile element end and / or on the distance from one of the side edges. Thus, a width of the support lip profile increase both in the direction of the support element edge and on the side edge and decrease in the opposite direction.

In order to be able to ensure sufficient stability of the support lip permanently, it is favorable if a maximum support lip profile element height or a maximum support lip profile element depth relative to the support lip outer surface region is smaller than half the thickness of the support lip in the area of the support lip outer surface region. In other words, this means in particular that in the region of the support lip profile elements, the thickness has a value which corresponds to about half of a thickness of the support lip in the area without support lip profile elements and a maximum of l, 5 times this thickness.

It is favorable if the contour of the supporting lip profile element edge of at least part of the support lip profile elements is rounded towards the supporting lip profile element end or tapers to a point. This property can also have all supporting lip profile elements. According to a further preferred embodiment of the invention can be provided that on the support lip, starting from the support lip edge and from this transversely, in particular vertically, away extending Stützlippenausnehmungen are formed, which extend over the entire thickness of the support lip. Such Stützlippenausnehmungen thus extend over the entire thickness, differently than preferably the profile elements in the form of profile recesses which extend over only a portion of the thickness of the support lip. Stützlippenausnehmungen thus form in particular openings of the support lip, which, when the support lip is placed substantially perpendicular to the hard surface to be cleaned, on the one hand by the support lip and the other part of the hard surface are limited. By Stützlippenausnehmungen liquid can pass between the support lip and the wiper lip at relatively steep employment of the support lip on the hard surface and be sucked through the suction port of the suction nozzle. In particular, the support lip recesses prevent a cleaning liquid wetting the hard surface from being pushed away by the support lip.

Conveniently, the profile elevations adjacent to the Stützlippenausnehmungen are arranged or formed and / or open the profile recesses in the Stützlippenausnehmungen. In the latter case in particular, in the case of a very strongly deformed support lip, cleaning liquid can first be passed through the profile depressions and then pass through the support lip recesses to the suction opening. Profile elevations are preferably arranged such that a Stützlippenausnehmung is disposed between the profile elevations. Two adjacent profile elevations then form a fluid channel, which also opens into the support lip recess.

It is favorable if the profile elevations adjoin one or both sides of the Stützlippenausnehmungen. In particular, profile elevations can be provided on both sides of a support lip recess in order, as described, to form a fluid channel which opens into a support lip recess. Preferably, the support lip profile elements extend to the support lip edge. Alternatively, they may also be slightly spaced, for example one or more millimeters, from the support lip edge.

Cleaning liquid can be conducted particularly well to the suction opening when at least a portion of the support lip profile elements extends to the Stützlippenausnehmungen. In particular, all support lip profile elements may extend to one or more Stützlippenausnehmungen.

Furthermore, it may be advantageous if at least two profile recesses merge into one another in the direction of the support lip edge and / or are connected to one another. As a result, in particular an increasing width of the profile depressions can be realized up to the supporting lip edge or up to the Stützlippenausnehmungen.

It is advantageous if the support lip profile element ends of the support lip profile elements open into a first fluid channel connecting at least two, in particular all, support lip profile elements, which runs in particular parallel or substantially parallel to the support lip edge. Such a fluid channel is thus spaced from the support lip edge and may in particular serve to receive cleaning fluid from the hard surface and into the support lip profile elements into or between them, depending on whether they are formed as profile depressions or profile increases.

It can further be provided that the support lip profile elements open in the direction of the support lip edge in a at least two, in particular all, support lip profile elements interconnecting second fluid channel, which runs in particular parallel or substantially parallel to the support lip edge. The second fluid channel also allows the collection of cleaning fluid before it can get into the suction port. According to a further preferred embodiment of the invention it can be provided that the support lip has a support lip width and that a distance of the support lip profile element ends of the support lip edge of at least a portion of the support lip profile elements is at most 90% of the support lip width. In particular, the distance is preferably at most 50% of the supporting lip width. Alternatively, the support lip profile element ends can also be arranged on an end of the support lip facing away from the support lip edge, that is to say in a transition region to a housing of the suction nozzle.

A particularly stable suction nozzle can be formed when the support lip is molded onto a housing part of the suction nozzle. Alternatively, it can also be detachably connectable to the housing part. So it can be replaced as a result of wear.

Furthermore, it is favorable if a number of the support lip profile elements corresponds to a multiple, in particular an integer multiple, of the number of support lip recesses. In particular, the number of supporting lip profile elements may correspond to the number of Stützlippenausnehmungen. Thus, a regular arrangement and design of the support lip profile can be achieved.

Furthermore, it is advantageous for the support lip to have a support lip inner profile with a plurality of support lip inner profile elements arranged or formed on the support lip inside, and if the support lip inner profile elements have support lip inner profile element surfaces facing away from the support lip inside, which part of the support lip inner surface form. Similar to the support lip profile, the support lip inner profile allows to improve a suction flow. The support lip inner profile elements may be formed as depressions and / or elevations. It is advantageous if the support lip inner profile elements are designed in the form of support lip inner profile projections. In this way, it can be achieved, in particular, that the support lip does not lie flat against the wiper lip. Rather, fluid channels may be formed between the support lip inner profile projections to enhance the passage of air and cleaning fluid therethrough.

Preferably, two support lip inner profile elements each define a support lip inner air guide between them. The support lip inner air guide may in particular be channel-shaped and thus limited on the one hand by the support lip and the two support lip inner profile elements and on the other hand by the wiper lip.

Furthermore, it is advantageous if a number of the support lip profile elements corresponds to a multiple, in particular an integral multiple of the number of support lip inner profile elements and / or the support lip inner air ducts. This has the advantage that in particular formed by the support lip profile elements fluid channels on the outside of the support lip open into each directly associated support lip inner air ducts and so an ideal flow of cleaning fluid and air can be achieved.

It is advantageous if a thickness of the support lip decreases towards the supporting lip edge. As a result, in particular contact pressure forces of the suction nozzle can be reduced. Further, for example, residues of cleaning fluid can be reduced when placing the suction nozzle.

It is favorable if the support lip is chamfered on its support lip outside to the support lip edge. By such a chamfer or bevel or even a reduced thickness of the support lip to the support lip edge is prevented in particular that the wiper lip is spread by the support lip of the hard surface. In addition, a reduction of a contact area between the support lip and the hard surface may reduce an amount of liquid remaining on the support lip. It is favorable if a bevel on the support lip outside of the support lip transitions tangentially into the support lip outer surface region and defines a bevel edge which runs parallel or substantially parallel to the support lip edge. Such a chamfer can be produced in a simple manner and in particular also has the advantages already mentioned above.

It is advantageous if a distance of Stützlippeninnenprofilelementenden the support lip inner profile elements of the support lip edge of at least a portion of the support lip inner profile elements is greater than half the support lip width. Thus, the support lip profile elements preferably extend over a length which corresponds to at least half the support lip width.

According to a further preferred embodiment of the invention it can be provided that a support lip width of the support lip transversely to the support lip edge at least 10 times a support lip thickness of the support lip and / or that a width of the wiper lip transversely to the wiper lip edge at least 5 times a Abstreiflippendicke the wiper lip corresponds. This ratio of support lip width to support lip thickness differs significantly from known ratios in conventional hard surface aspirators. In particular, an angle between the suction device or the suction nozzle and the hard surface to be sucked off can be varied within a significantly larger range, in particular to well over 90 °, whereby the function of the suction remains unchanged , Although an offset between the wiper lip edge and the supporting lip edge may remain constant in this manner, it becomes smaller relative to the enlarged support lip width or wiper lip width, so that its effects are also reduced. The support lip may continue to follow the course of the Abziehlippe. It may be favorable if the support lip width corresponds to at least 15 times the support lip thickness and / or the width of the wiper lip to at least 8 times the wiper lip thickness. The larger the specified ratio, the greater the angular range by which the hard surface suction device can be pivoted relative to the hard surface, without the function of the suction nozzle being significantly impaired. In addition, a tolerance requirement on the wiper lip is reduced by its greater width compared to wiper lips in suction nozzles known from the prior art. This can be further improved, in particular by reducing a distance between the wiper lip and the support lip and a reduction in the support lip thickness.

A further improvement in the functionality of the hard surface suction device can be achieved, in particular, if the support lip width corresponds to at least 25 times the support lip thickness and / or the width of the wiper lip to at least 15 times the wiper lip thickness.

In order to replace an optionally damaged or worn wiper lip, it is advantageous if it is detachably connectable to the suction nozzle.

According to a further preferred embodiment it can be provided that the suction nozzle comprises a suction nozzle housing and that a Abstreiflippenaufnahme is formed on the suction nozzle housing for non-positive and / or positive receiving a arranged on the wiper lip or formed coupling element. In this way, the wiper lip can be coupled with the suction nozzle housing in a simple manner and possibly also release it again.

The coupling element can be formed in a simple manner when it is in the form of a bead-like thickening running parallel to the wiper lip edge and forming a rear end of the wiper lip. So can For example, it can be pushed into the wiper lip receptacle parallel to the thickening.

The support lip inner profile elements preferably form spacer holding elements with stop surfaces for the wiper lip pointing toward the wiper lip. The spacer elements in particular prevent direct contact between inner surfaces of the wiper lip and the support lip, so that the suction opening can not be closed even with a bending of the support lip and the wiper lip. Thus, the cleaning liquid located on the hard surface can be optimally extracted.

Furthermore, it is favorable if the wiper lip on a wiper lip inner side defining a wiper lip inner surface defines a wiper lip inner surface, a wiper lip inner profile having a plurality of wiper lip inner profile elements arranged or formed on the wiper lip inner side and if the wiper lip profile elements are facing wiper lip profile element surfaces facing away from the wiper lip inner side have, which form part of the Abstreiflippeninnenfläche. Similar to the support lip, the wiper lip can also be equipped with a described wiper lip inner profile. The scraper lip inner profile elements can optionally form elevations and / or depressions.

It is favorable if the wiper lip inner profile elements are designed in the form of wiper lip inner profile projections. These allow in particular to specify a distance between the wiper lip and the support lip, so that they can not fully abut each other, whereby a flow of air and / or cleaning liquid could be prevented.

It is advantageous if the wiper lip inner profile elements form spacer holding elements with stop faces for the support lip pointing towards the support lip. Thus, flow channels between the support lip and the Ab- Scrape lip remain free, regardless of whether they are deformed when applied to the hard surface to be sucked or not.

It can also be advantageous if ends of the support lip inner profile elements pointing towards the support lip edge are spaced from the support lip edge or extend up to it. A distance has the particular advantage that over the entire front edge of the support lip, a volume flow of air and / or cleaning liquid is made possible.

Furthermore, it is favorable if the stripper lip edge pointing towards the ends of the Abstreiflippeninnenprofilelemente are spaced from the Abstreiflippenkante or erstcken up to this zoom. A spacing has the particular advantage that over the entire front area of the wiper lip, a volume flow of air and / or cleaning liquid can be achieved.

Moreover, it is advantageous if the support lip inner profile elements and / or the Abstreiflippeninnenprofilelemente are arranged curved or formed curved. In particular, a volumetric flow of air and / or cleaning liquid can be directed in a desired direction by the curvature, for example in the direction of the suction opening and / or the suction channel.

It is favorable if a curvature of the support lip inner profile elements and / or the wiper lip inner profile elements increases with decreasing distance of the same to a side edge. In other words, the closer they are arranged on the side edge, the more curved the support lip inner profile elements or the Abstreiflippeninnenprofil- elements. In particular, when the suction opening opens relatively centrally to the suction nozzle in the suction channel, a suction flow can be optimally performed in the side region of the suction nozzle. A particularly good guidance of the suction flow can be achieved if the support lip inner profile elements and / or the wiper lip inner profile elements are designed to be convexly curved essentially pointing towards the side edges. Thus, correspondingly curved flow channels can also be formed between the support lip and the wiper lip, which guide the suction flow in the direction of the suction opening and the suction channel. This is particularly favorable for very wide suction nozzles, in order to achieve a homogeneous suction flow over an entire extension of the suction nozzle.

In order to guide the suction flow in a defined manner, it is advantageous if support lip inner profile element ends pointing away from the support lip edge point towards the support lip internal profile elements in the direction of the suction channel.

Likewise, it is favorable if scraper lip inner profile element ends facing away from the wiper lip edge point in the direction of the suction channel. In both cases, such a suction flow can be guided exactly where it can get to the suction device on the shortest path.

Furthermore, it may be advantageous if flow channels formed between the supporting lip inner profile elements or between the wiper lip inner profiled elements have an increasing cross-sectional area towards the side edges. This results in particular in a higher pressure loss in the central region of the suction nozzle, which in turn, however, results in a more uniform distribution of the volume flow over an entire extension of the suction nozzle along the wiper lip edge.

In order to minimize flow resistance through the suction nozzle, it is expedient for the support lip inner profile elements and / or scraper lip internal profile elements to have a teardrop shape or substantially a teardrop shape.

A flow around the support lip inner profile elements or the wiper lip inner profile elements can be improved in particular by in that the teardrop shape has a substantially semicircular contour towards the supporting lip edge or the wiper lip edge, and that it tapers in a direction pointing away from it.

In order to guide the suction flow in a desired direction, it is advantageous if the drop shape defines a center line, which runs in particular curved.

According to a further preferred embodiment of the invention it can be provided that an inner boundary of the suction nozzle pointing towards the supporting lip edge is movable, in particular as a guide, which automatically moves the boundary in the direction of the supporting lip edge upon deformation of the supporting lip. Such a configuration further allows, in particular, a deformation of the suction nozzle.

In particular, when the wiper lip and the support lip are significantly extended compared to conventional suction nozzles, there is a greater free cross section in the region of the side edges thereof, through which false air can enter the suction nozzle and reduce its suction power. Therefore, it is favorable if at least one closure element is provided for the at least partial closing of a lateral opening formed between the wiper lip and the support lip.

Preferably, the at least one closure element completely closes the opening. In this way it can be prevented in particular that false air can penetrate into the suction nozzle, which reduces a suction power.

It can be advantageous if the at least one closure element closes the opening in an opening region facing away from the support lip edge. Such an arrangement or design of the closure element has a greater effect in the rear region of the opening than in the front region, since a cross section in the rear region can be larger in particular than in the front region. The suction nozzle can be produced in a particularly simple manner if the at least one closure element in the form of a wall section is formed on the support lip or on the wiper lip. Of course, both the support lip and the wiper lip may comprise such a wall portion.

It is advantageous if the at least one closure element is formed transversely, in particular vertically, projecting from the support lip or from the wiper lip. Thus, even without being deformed, it can substantially completely close the opening.

Conveniently, the at least one closure element is formed from an elastic and / or flexible material. This makes it possible, in particular, for it to be pulled by a suction in the suction nozzle against an edge of the lip on which it is not arranged or formed. Thus, the suction flow can be used in particular to simultaneously close an opening supportive.

An assembly and manufacture of the suction nozzle is further simplified if the at least one closure element is formed integrally with the support lip or with the wiper lip.

In particular, in order to improve a deformation of the wiper lip and / or the support lip, it is advantageous if the closure element has one or more apertures or cuts.

According to a further preferred embodiment of the invention, it can be provided that the at least one closure element is designed in the form of a closure rib. This may be formed, for example, in the form of a flat projection, which, however, may also have an increasing height with increasing distance from the supporting lip edge or wiper lip edge. It is advantageous if the at least one locking rib is arranged or formed running transversely to the side edge. Such a closure rib forms a fluidic obstacle which, in particular due to a higher pressure loss, also results in a reduction of the secondary air flow through the opening.

Alternatively, the at least one locking rib could also be arranged transversely to the side edge or designed to close the opening completely or partially.

It is favorable if the closure rib is formed following a course of the adjacent support lip inner profile element or stripper lip inner profile element. In this way, the sealing rib can also carry the suction flow, in particular towards the suction opening and the suction channel.

It is advantageous if the wiper lip and the support lip define the suction opening between them. In this way, cleaning liquid, which is located on the hard surface to be cleaned, are sucked through the suction opening safely and defined.

The object stated in the introduction is also achieved according to the invention in a hard surface suction device of the type described at the outset, which comprises one of the advantageously designed suction nozzles described above.

The hard surface suction device then also has the advantages described above in connection with preferred embodiments of suction nozzles.

FIG. 1 schematically shows a portable hard surface cleaning device 10, specifically in the form of a hard surface suction device 12 designed as a portable handset that can be operated independently of the mains, with which liquid can be extracted from a hard surface, for example water from a window pane. The Hartflächenabsauggerät 12 can be held by a user with one hand on a handle 14 thereof and guided in the manner of a conventional, having a rubber lip puller on the hard surface along. The Hartflächenabsauggerät 10 includes a housing 16 which also forms the handle 14 and a suction device 18 with a suction turbine 20 and an electric motor 22 for driving the same receives.

In the housing 16 is also at least one rechargeable battery, in particular a lithium-ion battery, arranged to supply power to the electric motor 22nd

The housing 16 further defines a standing surface 26, which allows the Hartflächenabsauggerät 12 in an upright position, as shown schematically in Figure 1, on a footprint, such as a table surface, to be able to set.

On the housing 16, a recess is formed, in which a removable dirty liquid tank 28 is arranged. It serves to accommodate

Dirty liquid that has been transported with the suction device 18.

On the upper side, that is to say facing away from the standing surface 26, the housing 16 of the hard-surface suction device 12 can be detachably connected to a suction nozzle 30. In particular, for cleaning purposes, the suction nozzle 30 can be removed from the housing 16.

The construction of the suction nozzle 30 will be explained in more detail below in connection with FIGS. 2 to 6.

The suction nozzle 30 comprises a suction nozzle housing, designated overall by the reference numeral 32, which is formed in several parts. In a Saugdü- sengehäuseunterteil 34, a suction channel 36 is arranged, the rear end 38, also referred to as Saugkanalende, with the housing 16 can be coupled. In this way, the end 38 of the suction channel 36 is coupled to the suction device 18. The suction channel 36 defines with its end facing away from the end 38 a straight, optionally curved, extending suction opening 40 which is formed between a wiper lip 42 and a cooperating with this support lip 44. The wiper lip 42 and the support lip 44 are formed of a flexible material.

The construction of the suction nozzle 30, in particular the support lip 44, will be explained in more detail below in connection with FIGS. 2 to 10.

The support lip 44 defines a support lip edge 46, the wiper lip 42 a wiper lip edge 48, which defines a front end 50.

The support lip 44 has, on a support lip outer side 54, which points away from the wiper lip 42 and which defines a support lip outer surface 56, a support lip profile 58 with a plurality of support lip profile elements 60 arranged or formed on the support lip outer side 54. The support lip profile elements 60 have support lip profile element surfaces 62 pointing away from the support lip outer side 54 and forming part of the support lip outer surface 56. This is particularly evident in FIGS. 4 and 9.

The embodiment of the suction nozzle 30 shown in the figures, all support lip profile elements 60 in the form of profile recesses 64 are formed. These can optionally also be designed as profile elevations.

The support lip outer surface 56 defines a support lip outer surface region 66 that does not have or support supporting lip profile members 60. He is thus not defined by the support lip profile 58. The support lip profile elements 60 transition tangentially into the support lip outer surface region 66. They form with this a common support lip profile element edge 68. This is, as can be seen in particular in Figures 4 and 9, substantially U-shaped and pointing in the direction of the support lip edge 46 out open. The support lip profile element edge 68 is parabolic or substantially parabolic.

The support lip profile elements 60 extend transversely in a direction, namely perpendicular to the support lip edge 46. This defines a straight line 70 and a plane 72, respectively.

The support lip outer surface 56 is in a basic position in which the support lip 44 is undeformed, flat or substantially planar. Thus, the support lip outer surface area 66 in the basic position of the support lip is flat or substantially planar.

A support lip profile element width 74 of each support lip profile element 60 increases, starting from a support lip profile element end 76 facing away from the support lip edge 46, towards the support lip edge 46. As can be seen in FIGS. 4 and 9, the support lip profile element width 74 increases in dependence on a distance 78 from the support lip profile element end 76.

The support lip 44 has two lateral edges 80 extending transversely to the support lip edge 46.

As schematically illustrated by way of example in FIG. 9, the support lip profile element width 74 or a projected area defined by the support lip profile element edge 68 increases with decreasing distance 82 of the support lip profile element 60 from one of the two side edges 80. In other words, a support rib profiieiement 60 is the wider, the closer it is located at one of the side edges 80.

A contour of the support lip profile elements 60 can be defined in the embodiment of the suction nozzle 30 shown in the figures, in particular by a function which depends on the distance 78 from the support lip profile element end 76 and / or the distance 82 from one of the side edges 80. A maximum support lip profile element depth 84 relative to the support lip outer surface area 66 is less than half the thickness 86, which can also be referred to as support lip thickness, of the support lip 44 in the area of the support lip outer surface area 66.

It can be seen in particular in the enlarged detail of FIG. 9 that the contour of the supporting lip profile element edge 68 towards the supporting lip profile element end 76 is rounded off. Optionally, the contour can also end sharply here.

The support lip 44 further comprises starting from the support lip edge 46 a plurality of substantially regularly juxtaposed Stützlip- penausnehmungen 88 which extend transversely to the support lip edge 46, namely perpendicular to this, over the entire thickness 86 of the support lip 44. By way of example, FIG. 7 shows a surface 90 of a hard surface 92 to be cleaned, which projects perpendicularly with respect to the support lip 44. The Stützlippen- recesses 88 thus form in cooperation with the surface 90 openings 94 through which cleaning fluid and air can flow.

The profile recesses 64 are arranged such that they open into the support lip recesses 88. They thus extend as far as the support lip recesses 88, which thus virtually form part of the support lip edge 46.

In the embodiment of the suction nozzle 30 shown in the figures, the profile recesses 64 are separated from each other. Alternatively, it is conceivable to bring the profile depressions 64 together in the direction of the support lip edge 46 and to form them into one another or to connect them to one another.

Optionally, the support lip profile element ends 76 of the support lip profile elements 60 can be inserted into at least two, for example all, support lip sections. Profile elements 60 interconnecting first fluid channel 96 open. This can in particular run parallel or substantially parallel to the supporting lip edge 46. In the enlarged detail view of Figure 9, such a first fluid channel 96 is shown schematically by dashed lines.

Furthermore, the support lip profile elements 60 can open in the direction of the support lip edge 46 in a at least two, in particular all, support lip profile elements interconnecting second fluid channel 98. This can in particular run parallel or substantially parallel to the supporting lip edge 46. Such a second fluid channel 98 is also shown schematically in dashed lines in the enlarged detail of FIG.

The support lip 44 has a support lip width 100. A distance 102 of the support lip profile element ends 76 from the support lip edge 46 of the support lip profile elements 60 is less than one half of the support lip width 100. In the embodiment shown in the figures, the distance 102 carries about one quarter of the support lip width 100.

As shown by way of example in FIG. 7, the support lip 44 is injection-molded onto a lower housing part 104 of the suction nozzle 30.

Preferably, the number of support lip profile elements 60 corresponds to the number of Stützlippenausnehmungen 88. Optionally, an integer multiple or any multiple of support lip profile elements 60 may be provided in relation to the Stützlippenausnehmungen.

The support lip 44 optionally further comprises, on a support lip inner side 106 which faces the wiper lip 42 and defines a support lip inner surface 108, a support lip inner profile 110 with a plurality of support lip inner profile elements 112 arranged or formed on the support lip inner side 106. These also have support lip inner profile element surfaces 114 facing away from the support lip inside 106 and forming part of the support lip inner surface 108. The support lip inner profile elements 112 are formed in the form of supporting lip inner profile projections 116. Two support lip inner profile elements 112 each define a support lip inner air guide 118 between them.

The number of supporting lip profile elements 60 in the exemplary embodiment of the suction nozzle 30 shown in the figures corresponds to the number of support lip inner profile elements 112 and the support lip inner air ducts 118. This is evident in particular from FIG.

The thickness 86 of the support lip 44 decreases towards the support lip edge 46 out. The support lip 44 is bevelled on the support lip outer side 54 to the support lip edge 46 and has a chamfer 120 on. The chamfer 120 or bevel on the support lip outer surface 54 transitions tangentially into the support lip outer surface region 66 to define a chamfer edge 122 that is parallel or substantially parallel to the support lip edge 46.

A distance 124 of support lip inner profile element ends 126 of the support lip inner profile elements 112 from the support lip edge 46 is greater than half the support lip width 100.

The support lip width 100 preferably corresponds to at least 10 times the thickness 86 of the support lip 44. A width 128 of the wiper lip 42 transverse to the wiper lip edge 48 also corresponds to at least 5 times a wiper lip thickness 130 of the wiper lip 42. This ratio can also be at least 15 or at least 25 for the support lip 44 amount, for the wiper lip 42 at least 8 or at least 15.

The wiper lip 42 is releasably connectable to the suction nozzle 30. The suction nozzle 30 has a suction nozzle housing 132 on which a Abstreiflippenaufnahme 134 is formed. In this, a coupling element 136 formed on the wiper lip 42 can be received positively and / or positively. The coupling element 136 is in the form of a bead-like, parallel to Abstreiflippenkante 48 extending, a rear end 138 of the wiper lip 42 forming thickening 140 is formed.

The support lip inner profile elements 112 define spacer elements 142 with the wiper lip 42 for the wiper lip 42 facing the wiper lip 42. Front tips 146 of the support lip inner profile elements 112 facing the support lip edge 46 are chamfered or chamfered.

The ends 146 of the support lip inner profile elements 112 extend up to the support lip edge 46. Optionally, they may also be spaced or formed from this.

As can be clearly seen in FIGS. 7 and 8, the support lip inner profile elements 112 are arranged or curved in a partially curved manner. A curvature thereof increases with decreasing distance toward the side edges 80. The support lip inner profile elements 112 are formed on the side edges 80 facing out substantially convex curved.

The support lip inner profile element ends 126 point in the direction of the suction channel 36.

Between the support lip inner profile elements 112 formed flow channels 148 and the Stütziippeninneniuftführungen 118 have to the side edges 80 towards an increasing cross-sectional area. This improves flow through the suction opening 40 defined between the wiper lip 42 and the support lip 44.

In particular, in the enlarged detail view in FIG. 8, the support lip inner profile elements 112 have a teardrop shape or a teardrop shape. This has the support lip edge 46 towards a substantially semicircular contour. Pointing away from the support lip edge 46, the drop shape runs pointedly. The teardrop-shaped tion of the support lip inner profile elements 112 defines a center line 150, which may extend in particular in the support lip inner profile elements 112 in the region of the side edges 80 curved.

Optionally, a gate can be provided, which forms an inner boundary of the suction nozzle 30. This may be designed to be movable, so that it automatically moves the boundary in the event of deformation of the support lip 44 in the direction of the support lip edge 46. This variant is not shown in the figures.

The suction nozzle 30 further comprises two closure elements 152, which at least partially, preferably completely close a formed between the wiper lip 42 and the support lip 44 side opening 154. Optionally, the closure elements 152 may be formed such that they close the opening 154 in an opening region 156 facing away from the support lip edge 46, which is shown schematically in dashed lines in FIG. The closure elements 152 are formed in the form of wall sections 158 on the support lip 44. Alternatively, the closure elements 152 could also be arranged or formed on the wiper lip 42.

The wall sections 158 are formed transversely, in particular perpendicularly projecting from the support lip 44. They are formed of an elastic or flexible material and preferably formed integrally with the support lip 44 or alternatively with the wiper lip 42.

Optionally, the closure elements may have one or more apertures 160 having openings 160, which are drawn as dashed lines as optional features in FIG. 9 in the detail enlargement.

Alternatively, the closure elements may be in the form of one or more sealing ribs extending transversely to the side edge 80 and optionally arranged or formed following a course of the adjacent support lip inner profile element 112.

The suction nozzle 30 makes it possible in particular, when applying the support lip 44 to the hard surface 92, both the support lip 44 and the cooperating with this wiper lip 42 to deform so that the housing 16 of the Hartflächenabsauggeräts 12 by an angle of up to 90 ° or more can be pivoted. This allows the Hartflächenabsauggerät applied to a vertical hard surface 92 with the suction nozzle 30 and, for example, a floor-deep window from top to bottom in one go and to pivot the housing 16 near the bottom so far that it does not with the ground comes into contact. The support lip 44 and wiper lip 42 are greatly deformed. Due to the support lip profile 58, however, the function of the Hartflächenabsauggeräts 12, in particular a forgiving use for an operator, guaranteed to achieve a perfect cleaning effect for befindliches on the hard surface 92 cleaning liquid.
