From the CN 200977129 Y a steam mop is known.

The invention has for its object to provide a floor nozzle of the type mentioned, which can be formed with low mass and has extensive possibilities of movement.

This object is achieved in the case of the floor nozzle mentioned above according to the invention that a holding body is provided, a holding device is provided, which is arranged on the holding body and is designed to hold a cleaning cloth, a tubular element is provided which is arranged on the holding body via a hinge device is, wherein the hinge means comprises a first joint, via which the holding body is pivotable about a first pivot axis to the tubular element, and wherein the hinge means comprises a second hinge over which the support body is pivotable about the second pivot axis transverse to the first pivot axis to the tubular member, and includes spring means associated with the first hinge and which upon pivoting of the support body towards the tubular member a basic position about the first pivot axis exerts a restoring force which tends to bring the holding body in the basic position.

By the first joint associated spring means can (if there is no external force) automatically bring the holding body to the pipe element in the basic position. In particular, it is not the weight of the holding body necessary to reach the basic position. As a result, the holding body and overall the floor nozzle can be formed with low mass.

For example, this makes it possible to form the holding device in a simple manner and provide, for example, Kletthaltestellen for the cleaning cloth. The floor nozzle can be realized with a great flexibility (by the rotation about the first pivot axis and the second pivot axis).

This results in a high maneuverability and it can also clean otherwise difficult or unreachable places.

In particular, it is also possible to design the floor nozzle flat at least in edge areas in order to achieve a ride-on, for example, on furniture. The first pivot axis is in particular a pitch axis for a pitch mobility of the holding body relative to the tubular element. For example, the first pivot axis is parallel or coaxial with a longitudinal axis of a part of the tubular element. Furthermore, it is provided that the second pivot axis is a roller axis for a roll mobility of the holding body relative to the tubular element. The second pivot axis is in particular parallel to a width direction, in which the holding body has its greatest extent. In particular, the second pivot axis is parallel to a spacing direction between lateral outer ends of the holding body. The distance between an outer end of the tubular element or of a stem which is seated on the tubular element can be adjusted relative to a surface to be cleaned via the second pivot axis.

It is favorable if the spring device assigned to the first joint comprises at least one torsion spring (and in particular exactly one)

Torsion spring comprises), which is formed in particular opening and closing. This makes it possible to realize a pivotability (rotatability) in a first pivoting direction and in a second pivoting direction opposite to the first pivoting direction.

In an alternative embodiment, the first joint is associated with a link track with link element and counter element, wherein the spring device (for the first pivot axis) is supported on the link element. By a relative rotation about the first pivot axis takes place a relative movement between the link element and the counter element and in particular, this movement has a linear component. As a result of the support of the spring device, which is formed in particular by one or more spiral springs, the spring device can then be compressed during a deflection out of the basic position. With a corresponding configuration of the link element and the counter element, a symmetry with respect to the rotation about the first pivot axis in a first pivot direction and in a second pivot direction opposite to the first pivot direction can be achieved. The compressed spring means causes a restoring force, which tends to bring the tubular element and the holding body in their relative normal position. In particular, the link element is rotationally fixed relative to the first

Pivoting axis connected to the holding body and the counter element is rotatably connected to the first pivot axis connected to the tubular element. In this embodiment, in particular the first spring device is then supported at one end on the tube device and supported at the opposite end on the link element, which in turn is then rotatably connected to the holding body with respect to the first pivot axis. It is then further provided in particular that the

corresponding slide track, which is formed from link element and counter element, and the corresponding spring device are arranged protected in a tube piece, which is rotatably connected with respect to the first pivot axis with the holding body.

It is particularly advantageous if the basic position of the first joint is a symmetrical position of the holding body to the tubular element and the holding body to the tubular element from the basic position in a first pivoting direction and in a second pivoting direction opposite to the first pivoting direction is pivotable. This corresponds to a pitch mobility in oppositely oriented pivot directions. This results in a high maneuverability for the floor nozzle. The spring means associated with the first hinge provides for an automatic return to the home position when there are no external forces.

In particular, a pivoting angle range of the holding body is to the

Pipe element for pivoting about the first pivot axis (for a pitch mobility) relative to the basic position at at least ± 60 ° and in particular at least ± 70 ° and in particular at least ± 90 ° and in particular at least approximately ± 90 °. This results in a high maneuverability.

It is advantageous if the spring device associated with the first joint is designed such that at least approximately the same restoring force is achieved with the same deflection in the first pivoting direction and in the same direction the second pivoting direction acts. This results in easy operability. The basic position can be achieved easily.

In one embodiment, the first hinge comprises a first tube piece and comprises a second tube piece, wherein the second tube piece is rotatably mounted in the first tube piece about the first pivot axis, and one of the tube pieces of the first tube piece and the second tube piece with respect to the first pivot axis with rotation the tube member is connected and the other tube piece with respect to the first pivot axis rotatably connected to the holding body. In particular, the tube piece non-rotatably connected to the tube element is part of the tube element. The first joint can be formed in a simple way. It is easy to pass fluid through the first joint and provide it to a fluid distributor.

It is advantageous if the second tube piece has a fluid passage area. This results in a simple structural design while minimizing the number of components required and minimizing the mass for the floor nozzle. Fluid and, in particular, steam can then be introduced to a held cleaning cloth via the fluid passage region.

A simple structural design results when the first joint associated spring device is supported on the first pipe section and the second pipe section. As a result, a restoring moment can be provided in a simple manner if a deflection about the first pivot axis takes place from the basic position.

The result is a structurally simple construction, when the second joint comprises a fluid distributor, via which fluid can be fed to a lower side of the holding body. It can then be fed through the second joint or via the second joint of a lower side of the holding body and in particular a distribution space fluid (steam). It is favorable if the fluid distributor is or comprises a tee. This makes it easy to realize the second joint. The second joint can be easily coupled to the first joint. Furthermore, it results in a simple way an optimized fluid (steam) to the cleaning cloth.

It is favorable if the second joint comprises a distributor tube which is mounted pivotably on the holding body about the second pivot axis. The manifold serves on the one hand for the distribution of fluid (steam) and coupling to a distribution space of the holding body. On the other hand, the manifold can form a shaft of the second joint and it can be realized in a simple manner, the rotation about the second pivot axis for roll motion.

In particular, a tube piece is arranged on the distributor tube, which is part of the first articulation and in particular is pivotable relative to the tube element about the first pivot axis. It can be achieved in a simple manner, a mechanical coupling between the first joint and the second joint, wherein a fluid passage and thus a provision of fluid to the manifold is realized in a structurally simple manner.

It is preferably provided that a spring device associated with the second joint, which in particular comprises one or more torsion springs (and preferably comprises exactly one torsion spring), is supported on the distributor tube and the holding body. It can be achieved in a simple way a restoring moment.

It is advantageous if the pipe element is a manifold or part of a

Krümmers is. It can then for example be associated with a

Mop can be achieved that a cleaning cloth, which is held on the holding body, all over touches a surface to be cleaned, and a Stem of the mop is at an oblique angle to the surface, so that there is an optimized guidance over the surface to be cleaned.

It is favorable if the manifold comprises a first region and a second region, wherein longitudinal axes of the first region and of the second region are oriented at an acute angle to one another and in particular the second region is part of the first joint. This results in a simple structural design. Preferably, the tube element has a coupling for a rigid tube and / or a hose and / or an actuating pistol, wherein in particular a coupling connection is detachable. This results in extensive application possibilities. For example, a mop can be realized in a simple manner via a coupling of the tubular element to a rigid tube.

It is also advantageous if the second joint is associated with a rear part, which endeavors to bring the holding body to the first tube element with respect to the second pivot axis in a basic position. It is then not the weight of the holding body necessary to reach the basic position. If no external force acts, the home position is automatically reached via the rear part. As a result, for example, the floor nozzle can be connected to a carpet slider in a simple manner, or a cleaning cloth can be fixed or detached in a simple manner.

It is favorable if the rear part device is a spring device and in particular comprises at least one torsion spring and in particular exactly one torsion spring. This results in a compact, structurally simple construction.

It is advantageous if the pipe element about the second pivot axis starting from the basic position at least in a first pivoting direction in a pivot angle range of at least 60 ° and in particular

at least 65 ° and in particular at least 70 ° and in particular at least 75 ° is pivotable relative to the holding body. This results in a high maneuverability. The specified angle value is the upper limit for the possible tilt angles (from 0 ° to the upper limit).

In one embodiment, it is provided that the basic position is adjusted so that, starting from the basic position, the tubular element is pivotable only in a first pivoting direction and a pivoting in a second pivoting direction is blocked opposite to the first pivoting direction. As a result, a recoverability only in one

Pivoting direction can be realized.

It is advantageous if the holding body has an open area, in particular in the form of a recess, wherein the tube element is connected to the holding body via the hinge device in the region of the free area.

As a result, a high mobility of the tubular element relative to the holding body can be realized in a simple manner. This results in a space-saving design.

In one embodiment, the holding body has a first area, has a second area connected to the first area and has a third area connected to the second area, wherein the hinge device is arranged on the second area. In this way, it is possible to form the first area and the third area with a relatively small height. This allows a good driving under furniture and the like.

In particular, the first region and the third region are at least approximately the same and are in particular arranged and formed symmetrically with respect to the second region. This results in a structurally simple construction. It is then favorable for the reasons mentioned, if the first region and the third region have a lower maximum height with respect to an envelope plane for a lower side of the holding body than the second region. The second area has a greater height due to the positioning of the hinge device. The first region and the third region are configured such that they then have a low height for improved rideability.

It is particularly favorable when the maximum height of the first

Region and / or the third region is at most 25 mm and in particular at most 20 mm and in particular at most 17 mm.

Furthermore, it is favorable if the second region is a relatively "restricted" region of the holding body with regard to its width dimensions and, with respect to a total width of the holding body between opposite lateral ends, the second region has a width of at most 45% and in particular at most 40% and in particular at most 35% of the total width. This results in good drive-through for a relatively large area of the holding body.

It is favorable if the floor nozzle without cleaning cloth has a mass of at most 240 g and in particular at most 230 g and in particular at most 210 g. This results in a high maneuverability. The automatic reset by the first joint associated spring device allows an automatic reaching the basic position relative to the first pivot axis without "help" the weight of the holder body.

It is advantageous if a distribution space is formed on an underside of the holding body, in which fluid can be coupled, wherein the distribution space is covered by the cleaning cloth when held on the holding body cleaning cloth. This allows the cleaning room to be cleaned via the distribution room. apply a supply of fluid (in particular steam). This results in an optimized cleaning result.

It is favorable if web elements are arranged in the distribution space. These can serve to distribute fluid onto the cleaning cloth. Furthermore, a certain mechanical action on a surface to be cleaned can be realized (covered by the cleaning cloth).

It is particularly advantageous if the holding body has a first lateral end and an opposite second lateral end, and the holding device has one or more holding points for the cleaning cloth, which lie on the holding body between the first lateral end and the second lateral end, and in particular one Have extension length in a width direction between the first lateral end and the second lateral end. It can be so easily fix the cleaning cloth to the holder body. For example, there are no Tuchklemmeinrichtungen or the like necessary. In turn, the floor nozzle can be formed with low weight. Furthermore, the cleaning cloth can be fixed over a relatively large area on the holding body.

This prevents sagging of the cleaning cloth

or at least reduce it.

It is advantageous if a total width as the sum of all widths of the stop in the width direction is at least 30% and in particular at least 40% of a total width of the holding body in the width direction. This results in an effective fixation. It can be avoided by hanging or at least reduce.

The result is a structurally simple construction, when the holding body has a skirt, on which the at least one stop is arranged, wherein the edge strip is formed in particular circumferentially. The skirt preferably surrounds a distribution space over which the cleaning cloth fluid is provided. Due to the sidebar is a relatively large area provided, on which the holding device is formed or can be positioned.

It is advantageous if a plurality of spaced stops and in particular evenly spaced stops are provided.

As a result, an effective fixation of the cleaning cloth while avoiding sagging can be achieved.

It is provided in particular that the at least one stop is formed so that when placing the holding body on the cleaning cloth a fixation of the cleaning cloth to the holding device can be produced and / or that a fixation of the cleaning cloth on the holding body by pulling away from the cleaning cloth in one direction is solvable. This results in an easy fixation option or for an operator

Possible solution.

It is particularly advantageous if the at least one stop is a Kletthaltestelle with Velcro hooks for a counter-stop on the cleaning cloth. It can thereby achieve a fixation of the cleaning cloth over the holding device on the holding body over a relatively large area, the fixation is easy to produce and a solution of the fixation is possible in a simple manner.

It is advantageous if a Kletthaltestelle is integrally formed on the holding body. Corresponding Velcro hooks are produced, for example, in the manufacture of the holding body integrally thereto by injection molding.

It is favorable if the cleaning cloth is designed so that it projects beyond the holding body at least on one side and in particular on all sides when fixed to the holding body. About the corresponding superior area of the cleaning cloth to the holding body can be a "bumper" realize, which is a stop of the holding body, for example prevents or at least dampens on a wall, a door or a piece of furniture.

It is favorable if the cleaning cloth has at least one tab which protrudes beyond the holding body when the cleaning cloth is fixed to the holding body and which serves to release the cleaning cloth from the holding apparatus. For example, if the floor nozzle with the cleaning cloth fixed thereto is placed on a floor, an operator can place his foot on the tab and then pull the floor nozzle upwards. As a result, the cleaning cloth can be detached from the holding device without the operator having to bend over or having to touch the floor nozzle.

It is favorable if the cleaning cloth is not held against the holding body when the cleaning cloth is (correctly) fixed to the holding device. This results in good usability with optimized cleaning result.

In one embodiment, the floor nozzle comprises a (detachable) carpet slider, in which the holding body can be used, in particular with a cleaning cloth fixed thereto. A carpet glider is used to refresh textile floor coverings. This results in extended application possibilities for the floor nozzle. By automatically reaching the home position relative to the first pivot axis (and also preferably with respect to the second pivot axis), the floor nozzle can be easily connected to the carpet slider.

According to the invention, a mop is provided, which is provided with a floor nozzle according to the invention. Furthermore, a steam cleaner is provided according to the invention, comprising a steam generating device with a steam generator and a floor nozzle according to the invention or a mop according to the invention.

19 explosion-related parts in Figure 20 are composed. An embodiment of a steam cleaner 8 includes a steam generating device 10. In one embodiment, the steam generating device 10 is a mobile device on which a detachable water tank 12 is arranged. The steam generating device 10 includes a steam generator 14 disposed within a housing. The steam generator 14 generates water vapor from liquid water provided from the water tank 12.

The steam generator 14 is for example a water heater or is designed as a boiler steam generator.

To the steam generating device 10, a hose 18 is connected via a corresponding plug 16. The hose 18 leads to an actuating pistol 20 with a handle 22. The steam cleaner 8 comprises a mop 24. The actuating gun 20 is part of this mop 24. The mop 24 can be held over the handle 22 of the actuating gun 20 and lead.

The mop 24 comprises a stem 26. The stem 26 is formed from one or more tubes 28a, 28b. In the exemplary embodiment shown in FIG. 1, the handle 26 comprises a first tube 28a and a second tube 28b which are releasably connected to one another. The tube 28b is connected to the actuating gun 20. The actuating pistol 20 has an actuating element 30, via which a fluid flow through the actuating pistol 20 and thus a fluid coupling into the tube 28b can be released or blocked.

The handle 26 is detachably connected to a floor nozzle 32. At the bottom nozzle 32 sits a textile cleaning cloth 34, which is formed in particular as a microfibre cloth.

The cleaning cloth 34 has an underside 36 which can be placed on a surface to be cleaned and over which this surface to be cleaned can be wiped. One of the bottom 36 opposite back 38 can be apply fluid and in particular steam via the floor nozzle 32. The steam is provided by the steam generator 14 of the steam generating apparatus 10 and provided via the hose 18 of the actuating gun 20. By actuating the actuating element 30, this fluid can flow through the handle 26 and act on the floor nozzle 32, the cleaning cloth 34 on the back 38.

It is also possible, for example, for the floor nozzle 32 to be connected directly to the actuating gun 20 or, for example, to be connected to the pipe 28b and for the pipe 28a to be omitted.

For wiping a surface to be cleaned and in particular a hard floor surface over the mop 34, a standing operator can hold the mop 34 on the handle 22 while actuating the actuating element 30.

An embodiment of a floor nozzle 32 according to the invention (FIGS. 7 to 16) comprises a holding body 40. The holding body 40 is designed in particular as a holding plate. The holding body 40 has a top 42 and a bottom 44. On the bottom 44 a distribution space 46 is formed for fluid, which is closed to the top 42 through a plate member 48.

The holding body 40 comprises a skirt 50 (FIG. 8), which is circumferential and surrounds the distribution space 46. On the edge strip 50, a holding device 52 is arranged for the cleaning cloth 34. This will be described in more detail below.

The holding body 40 has a first lateral (lateral) end 54. It also has an opposite second lateral end 56. The holding body 40 extends between the first lateral end 54 and the second lateral end 56 in a width direction 58 (FIG. 7) and has a width B in the width direction 58 (FIG. 8). Further, the holding body 40 has a front end 60 and an opposite rear end 62. Perpendicular to the width direction 48 is a transverse width direction 64 between the front end 60 and the rear end 62nd

The holding body 40 has a greater width in the width direction 58 than in the transverse width direction 64. The holding body 40 has at least

approximately a rectangular outer contour with the longer side along the width direction 58.

The holding body has a first region 66 (FIG. 12), which contains the first lateral end 54 and extends away from it in the width direction 58. In the width direction 58, the first region 66 is followed by a second region 68 which is connected to the first region 66 and in particular is integrally connected. The second area 68 is followed in the width direction 58 by a third area 70, which contains the second lateral end 56 and in particular is integrally connected to the second area 68. The first region 66, the second region 68, and the third region 70 collectively include the forward end 60 and the rearward end 62.

The first region 66 has a width Bi in the width direction 58. The second region 68 has a corresponding width B ₂ . The third region 70 has a width B ₃ . The sum of the widths Bi, B ₂ , B ₃ gives the width B of the holding body 40 in the width direction 58.

In the first area 66 and the second area 70, the holding body (without cleaning cloth 34) has a maximum height Hi (first area 66) or H ₃ (third area 70), which is smaller than the height H ₂ in the third area 68. The heights are based on a height direction 72 on the holding body 40, which is perpendicular to the width direction 58 and perpendicular to the transverse width direction 64. These heights Hi, H ₂ and H ₃ are with respect to an envelope plane 74 (FIGS. 9, 10) on the underside 44 of the holding body 40, which bears against the edge strip 50.

In one exemplary embodiment, with regard to a non-pivoted state of the holding body 40 relative to a pitch axis, the holding body 40 is formed at least approximately symmetrically with respect to a mirror plane 76 (FIGS. 7, 9). The mirror plane 76 runs centrally through the third region 68 perpendicular to the width direction 58. In particular, the first region 66 and the third region 70 are formed at least approximately the same.

A maximum height Hi and H ₃ is preferably at most 25 mm and particularly preferably at most 20 mm and in particular at most 17 mm. In a specific embodiment, the heights Hi and H _{3 are} about 15 mm.

Due to the relatively small height of the holding body 40 to the lateral ends 54, 56 towards optimized cleaning possibilities arise in particular with a "submersibility" (under-ride) under furniture and the like. Furthermore, the holding body 40 can be material-saving and thus easy to train.

It is envisaged that the width B _{2 of} the second region 68 in the width direction 58 is at most 45%, and more preferably at most 40% and, for example, at most 35% of the total width B in the width direction 58. The proportion of the second area 68 relative to the total width B in the width direction 58 should be as small as possible.

The floor nozzle 10 comprises a pipe element 78, which has a corresponding coupling 80, via which the floor nozzle 32 can be connected to the steam generating device 10 in a fluid-efficient manner. The coupling 68 is in particular designed so that it with the pipe 28 a and 28 b or with the Actuating gun 20 is detachably connectable. Fluid is provided to the floor nozzle 32 via the pipe member 78.

The tubular element 78 is designed as a manifold with a first region 82 having a first longitudinal axis 84 and a second region 86 having a second longitudinal axis 88 (FIG. 14). The second region 86 is disposed at an angle to the first region 82; the second longitudinal axis 88 is oriented at an acute angle 90 to the first longitudinal axis 84. The tube element 78 can be traversed by fluid. By training as a manifold is a

Flow deflection from a transition from the first region 82 to the second region 86. The first longitudinal axis 84 and the second longitudinal axis are each parallel to main flow directions of fluid in the first region 82 and the second region 86. The first region 82 is particularly formed as a pipe stub in which the clutch 80 is arranged.

On the tube element 78 and in particular on a first region 82, a holding element 92 is arranged, for example in a hook shape, by means of which the floor nozzle 32 and in particular the mop 24 in a parking position of the steam generating device 10 can be fixed to this.

The acute angle 90 is in a range between about 35 ° and 50 °. In a specific embodiment, the acute angle 90 is approximately 42 °.

The tubular element 78 is held on the holding body 40 via a hinge device 94. The hinge device 94 enables a relative pivotability of the holding body 40 to the tubular element 78 about a first pivot axis 96 and about a second pivot axis 98, wherein the second pivot axis 98 is transverse and in particular perpendicular to the first pivot axis 96.

The tubular element 78 is arranged on the holding body 40 in the second region 68 via the hinge device 74. The greater height H ₃ at the second Area 68 is due to this arrangement of the tubular element 78 on the holding body 40.

The articulation device 94 comprises a first pivot 100 for the pivotability about the first pivot axis 96.

The first joint 100 is formed with the second region 86 of the tubular element 78. This second region 86 of the tubular element 78 is a second one

Pipe piece 102 which is rotatably mounted in a first tube piece 104 about the first pivot axis 96. The second tube piece 102 is rotatably connected to the tube member 78 with respect to the first pivot axis 96. It has a fluid passage region 106, through which fluid can flow. The first pivot axis 96 is coaxial with the second longitudinal axis 88.

The first pivot axis 96 lies in the mirror plane 76.

Due to the pivoting of the holding body 40 to the tubular element 78 about the first pivot axis 96, a pitching movement for the holding body 40 relative to the tubular element 78 is possible. The first pivot axis 96 is a pitch axis for a pitch mobility of the holding body 40.

The first joint 100 is associated with a first spring device 108. The first spring means 108 defines a basic position (cf., for example, Figure 7), in which the holding body 40 is aligned with its width direction 58 perpendicular to the mirror plane 76; In the basic position of the holding body 40 is symmetrical with respect to the tubular element 78. By the pitch mobility about the first pivot axis 96, starting from the basic position, which can be regarded as a zero-angle position, in a first pivoting direction 110 (Figure 10) and a second Pivoting direction 112 are pivoted opposite to the first pivoting direction 110.

The first spring device 108 is arranged and designed so that upon a deflection of the holding body 40 starting from the basic position, this endeavors to bring the holding body back into the basic position; the first spring device 108 has a restoring force for restoring the position of the holding body 40 to the tube element 78 in the basic position. The first spring device 108 is designed such that there is just a restoring force both during a pivoting in the first pivoting direction 110 and in the second pivoting direction 112.

In particular, the spring device 108 is designed so that essentially the same restoring force acts for the same amount deflection, that is, regardless of whether pivoting in the first pivot direction 110 or in the second pivot direction 112 is present, the same restoring force acts. In one embodiment, the first spring means 108 comprises one or more torsion springs 114. In particular, a single torsion spring 114 is provided.

The torsion spring 114 is positioned on the second tube piece 102 (the second portion 86 of the tube member 78) and is supported on the second tube piece 102 from the outside. It is supported on the first pipe section 104 inside. It is thereby positioned in a gap 116 between the second tube piece 102 and the first tube piece 104. The torsion spring 114 is designed to open and close, just to allow the restoring force both when pivoting in the first pivoting direction 110 and in the second pivoting direction 112. For example, the torsion spring is heat-treated in such a way that it provides an equal torsional moment with respect to both directions of pivoting 110 and 112 (in particular with respect to the same amount of deflection). By the pitch mobility of the holding body 40 with the first pivot axis (pitch axis) 96, the holding body 40 can be to the mirror plane 76th

pivot, wherein the basic position is a Symmetriestellung and a swing from the basic position eliminates this symmetry. A pivot angle range of the pitch mobility about the first pivot axis 96 is in particular in the range of at least ± 60 ° (ie from 0 ° to at least ± 60 °) and preferably at least ± 70 ° and preferably at least ± 90 ° and for example at ± 90 °. In this case, the magnitude of the same pivoting angle range in the first pivoting direction 110 and the second pivoting direction 112 is preferably present in terms of magnitude

Distinguish swing angle ranges in the orientation ("±") of the swing angle.

The hinge device 94 further comprises a second hinge 118 with the second pivot axis 98. The second pivot axis 98 is aligned transversely and in particular perpendicular to the first pivot axis 96. The second pivot axis 98 is parallel to the width direction 58 and thus to the direction of the longest extent of the holding body 40. The second pivot axis 98 for the pivoting of the holding body 40 to the tubular element 78 is a roll axis or roll axis for a roll mobility of the holding body 40 to the tubular element 78.

If, relative to the first pivot axis 96, the holding body 40 is in its basic position to the tube element 78 and is arranged symmetrically with respect to the mirror plane 76, then for any pivoting angle the pivoting of the holding body 40 to the tube element 78 remains around the second Swivel axis 98 receive the corresponding symmetry to the mirror plane 76.

In one embodiment, the second pivot axis 98 is at least approximately parallel to the front end 60 and the rear end 62, respectively.

The second joint 118 comprises a fluid distributor 120, via which (at each pivoting position of the holding body 40 to the tube element 78 relative to the first pivot axis 96 and the second pivot axis 98) fluid can be provided to the distribution space 46.

The fluid distributor 120 is designed in particular as a T-piece 122. The fluid distributor 120 and thus the second joint 118 has a distributor tube 124. This distributor tube 124 has a longitudinal extent parallel to the width direction 58 and forms a shaft of the second articulation 118.

The manifold 124 is rotatably supported at one or more jacks 126 about the second pivot axis 98. The socket or sockets 126 are arranged on the holding body 40 on the second region 68.

Relative to the mirror plane 96, the manifold 124 extends to both sides of the mirror plane 96.

For example, spaced bushings 126 are arranged on both sides of the mirror plane 76.

The fluid distributor 120 with the design as a T-piece 122 further comprises the first tube piece 104, which is arranged transversely and in particular perpendicular to the distributor tube 124 and thereby aligned parallel to the transverse width direction 64. The manifold 124 has openings 128 in the distribution space 46. In particular, in each case at least one opening 128 is arranged on both sides relative to the mirror plane 76. Fluid, which flows through the tube member 78 and thereby flows into the second tube piece 102, then flows into the manifold 124 and is introduced from there into the distribution space 46. This takes place at any pivotal position (both relative to the first pivot axis 96 and the second pivot axis 98) of the holding body 40 to the tubular element 78th

The T-piece 122 is disposed in relation to the second tube piece 102 such that fluid passage from the second tube piece 102 into the manifold tube 124 may occur with corresponding flow deflection with a subsequent main flow direction parallel to the width direction 58 and exit via the opening or openings 128 into the distribution room 46.

The second joint 118 is associated with a second spring device 130. This second spring device 130 exerts a restoring force on the holding body 40 with respect to the pivotability about the second pivot axis 98 and strives to bring the second holding body 40 with respect to its rollability in a basic position to the tubular element 78.

This basic position is shown for example in Figure 7 and Figure 3. In the basic position, the tube element 78 abuts, for example with a partial region 172 (FIG. 14), against a counter region 134 on the holding body 40. It is then a pivoting mobility starting from this basic position only in a pivoting direction 136 (Figure 14) possible. In one embodiment, the basic position relative to the second pivot axis 98 is such that the second pivot axis 98 is at least approximately parallel to the envelope plane 74. Starting from this basic position, the tube member 78 relative to the holding body 40 only in this pivoting direction 136 to the second

Swivel axis 98 are pivoted. If the swivel angle range in this basic position is related to the first longitudinal axis 84, then this swivel angle range is in particular at least 60 ° (ie from 0 ° to at least 60 °) and preferably at least 65 ° and preferably at least 70 ° and in particular at least 75 °. This will be explained in more detail below.

The second spring device 130 is supported both on the distributor tube 124 as (directly or indirectly) also on the holding body 40.

In one embodiment, the second spring means 130 comprises one or more torsion springs 138, and more particularly just one torsion spring 138. This torsion spring 138 is disposed on an arm of the manifold tube 124 and generates a corresponding torsional moment when a deflection of the holder body 40 relative to the tube member 78 from the Basic position and endeavors, as mentioned above, to restore this basic position by exercising a corresponding restoring force.

The holding body 40 has a free space 140, which is formed in particular as a recess. This free space 140 serves to arrange and position the articulation device 94 and is designed so that the corresponding pivoting movement between the tubular element 78 and the holding body 40 about the first pivot axis 96 and the second pivot axis 98 is made possible.

The free space 140 is covered by a cover 142.

The second spring device 130 is supported on an inner side of the cover 142; this support is the support on the holding body 40th 11 shows a view of the floor nozzle 32 from above, wherein with respect to the first pivot axis 96, the respective basic position is set and with respect to the second pivot axis 98, the corresponding basic position is set. FIG. 12 is the same view as FIG. 11 but with the lid 142 removed.

In a further embodiment (FIGS. 17 to 19), a tubular element 78 'is provided. This tube element 78 'is basically the same design as the tube element 78 described above.

A second tube piece 202 is non-rotatably connected to the tube element 78 '. This second tube element 202 is arranged at an angle to a coupling region of the tube element 78' as described above in connection with the tube element 78.

To form a first joint 200, the second tube piece 202 is rotatably arranged in a first tube piece 204 about a first pivot axis 196.

As described above with reference to the fluid divider 120, the second tube piece 204 is part of a fluid distributor 220. This fluid distributor 220 is fundamentally the same design as the fluid divider 120 and is rotatably connected to the holder body 40 about a second pivot axis 198. The holding body 40 is formed as described above. In the first tube piece 204, a link element 206 is positioned. This link element 206 is rotatably connected to the first pipe section 204 with respect to the first pivot axis 196. Relative rotation of the first tube piece 204 to the second tube piece 202 about the first pivot axis 196 causes the corresponding same relative rotation of the link element 206 about the first pivot axis 196 with respect to the second tube portion 202.

There is provided a first spring means 208, which for a provision of the second tube piece 202 relative to the first tube piece 204 after a deflection from the basic position, when the worrying for the deflection force is removed.

In one embodiment, the first spring means 208 comprises a coil spring 210, which is supported on a corresponding tab 212 of the second tube piece 202 and on the link element 206.

The link element 206 is configured in relation to the first spring means 208 such that upon rotation of the second tube piece 202 relative to the first tube piece 204 about the first pivot axis 196 from the home position, both in the first pivot direction and in the opposite second pivot direction , the coil spring 210 is compressed. This exerts a corresponding force, which endeavors to bring the second pipe section 202 back into its basic position.

In one embodiment, a counter element 214 for the link element 206 is formed on the second tube piece 202, on which the link element 206 is supported. As a result, a slide track is formed with a positive guidance of the link element 206 on the counter element 214.

The counter element 214 has a counter path 216 for the link element 206.

The counter path 216 is based on the basic position of the second tube piece 202 to the first tube piece 204 relative to the first pivot axis 296 formed symmetrically.

The counter-path 216 comprises, in particular, a first oblique "plane" 218a and a second oblique "plane" 218b (FIG. 19). These have opposite orientations and are symmetrical to each other. The inclined planes 218a and 218b have in particular curvatures for adaptation to the rotation about the first pivot axis 196. The link element 206 is adapted in its outer shape to the first inclined plane 218a and the second inclined plane 218b.

In FIGS. 17 and 19, the basic position for the second pipe section 202 to the first pipe section 204 is shown. The link element 206 is symmetrical with respect to the counter-track 216. The first spring device 208 with the spiral spring 210 is designed such that in the basic position no relative torque acts between the second pipe section 202 and the first pipe section 204 or this torque is so small that the Basic position can not be left alone by the force of the first spring means 208.

If a sufficiently large force is exercised, which for example

19, 20) causes a rotation of the first tube piece 204 relative to the second tube piece 202 (in the view according to FIG. 19, starting from the basic position to the left), then the slide element 206 slides with its corresponding counter track 216 on the first inclined plane 218a or the second inclined plane 218b, depending on the pivoting direction. This increases a distance of a support region of the link element 206 for the spiral spring 210 with respect to the counter element 214.

This in turn causes a compression of the coil spring 210.

To achieve this condition, an external force overcoming the force of the first spring means 208 is necessary.

When this external force, which causes just the rotation about the first pivot axis 196 from the basic position, is removed, then the force of the coil spring 210 presses the link element 206 against the counter path 216 and causes a rotation of the link element 206 about the first

Swivel axle 196 until the basic position is reached. This leads to a relative rotation of the first tube piece 204 to the second tube piece 202 until the basic position is reached. It is then reached the position shown in Figures 17 and 18 again.

The coupling of the fluid distributor 220 to the holding body 40 is as described above.

The floor nozzle 32 can be easily formed. In particular, it has a mass of at most 240 g and in particular at most 230 g and in particular at most 210 g, the mass consisting of the holding body 40, the tube element 78 (or 78 ') and the articulation device 94 (without cleaning cloth 34).

To produce the respective basic position of the holding body 40 to the tubular element 78 or 78 ', the weight of the holding body 40 is not necessary; the restoring force caused by the first spring device 108 or 208 causes an automatic reset relative to the first pivot axis 96 in the otherwise force-free state

196 or 196. The second spring device 130 causes the otherwise force-free state an automatic reset with respect to the second pivot axis 98 or 198. This provision is independent of the weight of the holding body 40th

If no external forces act, then the holding body 40 is to the tube member 78 and 78 'in its normal position with respect to the first pivot axis 96 and 196 and with respect to the second pivot axis 98 and 198. He thereby has a defined fixed position to the mirror plane 76 ,

As a result, as will be explained in more detail below, the cleaning cloth 34 can be fixed to the holding body 40 in a simple manner

or can be solved or it can be solved or produce a simple connection with a carpet glider. The holding device 52 for releasably holding the cleaning cloth 34 is arranged on the holding body 40 and arranged in particular on the edge strip 50. The holding device 52 is designed such that the cleaning cloth 34 can be releasably fixed to the holding body 40 without significant sagging.

The holding device 52 in particular comprises a plurality of stops 144 (FIG. 8). A corresponding stop 144 on the holding body 40 is a counter-stop 146 (cf., for example, FIG

Cleaning cloth 34 assigned. A fixation connection between a counter stop 146 and an associated stop 144 can be established. About these compounds, the cleaning cloth 34 is then held on the holding body 40 on the holding body 40 (releasably) for a cleaning process.

For example, spaced stops 144 are arranged on a first subarea 148 of the edge strip 50, on which the front end 60 lies, and a plurality of spaced ones are likewise located on an opposite second subarea 150 of the rim 50, on which the rear end 62 is located Stops 144 arranged.

A stop 144 has a longitudinal extent in a direction parallel to the width direction 58. In particular, a stop 144 has a width b, in this width direction 58.

It is provided in particular that the sums of all widths of the stops 144 is at least 30% and in particular preferably at least 40% and for example at least 50% of the total width B of the holding body 40 in the width direction 58. In the embodiment shown in FIG. 8, the total width of the stops 144 is bi + b ₂ + b ₃ .

It is favorable if in each case a stop 144 is located in the first subregion 148 and the second subregion 150 of the edge strip 50 in a projection region of the tubular element 78 (or 78 ') and in particular on the mirror plane 76; This effectively prevents or at least reduces sagging. In particular, uniformly spaced stops 144, which preferably also have the same width b, are arranged on the edge strip 50 and, in particular, are preferably arranged on the first section 148 and the second section 150. In one embodiment, the holding device 52 is formed as a Velcro connection and the stops 144 are Klettsaltestellen with Velcro hooks with the counter stops 146 of the cleaning cloth 34 is made possible.

In particular, hooks of the stops 144 are integrated in the skirt 50 and thus in the holding body 40 and, for example, integrally connected thereto.

If the cleaning cloth 40 is fixed to the holding device 52, then a back 152 of the cleaning cloth 34 is acted upon by fluid and in particular steam via the distribution space 46 during operation of the steam cleaner 8. The cleaning cloth 34, when fixed to the support 52, effectively creates a cover for the distribution space 46 down to the surface to be cleaned. A front side 154 of the cleaning cloth 34, which is opposite the back 152, serves to act on the surface to be cleaned.

On the holding body 40, web elements 156 are arranged in the distribution space 46, wherein in particular a plurality of spaced webs are arranged. is provided elements 156 (see, for example, Figure 8). The web elements 156 are in particular corrugated.

They serve for distributing fluid in the distribution space 46 and for uniformly loading the cleaning cloth 34 on its rear side 152 with fluid and in particular with steam. Furthermore, a certain mechanical force can be exerted on a surface to be cleaned via it, wherein they are covered by the cleaning cloth 34. The cleaning cloth 34 is provided with a tab 158 (see, for example, Figure 16). This tab 158 protrudes when fixed to the holding body 40

Cleaning cloth 34 on the holding body 40 addition.

In one embodiment, it projects rearwardly beyond the rear face end 62.

The tab 150 may be printed, for example, to indicate to an operator the back 152 as a side with the counter stops 146 for the retainer 52.

The tab 158 is used for easy detachability of the cleaning cloth 34 of the holding body 40th

For example, if the cleaning cloth 34 rests on a surface, then an operator can step on the tab 158 and remove the mop 24 with the holding body 40 upwards (indicated in Figure 16 by the arrow with the reference numeral 60). As a result, the connection between stops 144 and counter-stops 146 is released and thus the cleaning cloth 34 is detached from the mop 24.

The cleaning cloth 34 is preferably formed so as to protrude beyond the ends (lateral ends 54, 56, front ends 60, 62) of the holding body 40 when fixed to the holding body 40. An appropriate one projecting region 162 (see Figure 1) serves as a "stop damper", that is, as a bumper during a cleaning process. It is characterized a hard abutment of the holding body 40 of furniture, walls, doors and the like prevented or at least damped.

In one embodiment, the floor nozzle 32 includes a carpet slider 164, or associated with such a carpet slider 164.

The carpet slider 164 serves to refresh textile floor surfaces via steam.

The carpet slider 164 comprises a trough-shaped element 166 which has one or more openings 168 on its underside. Via the opening or openings 168, in a refresh operation, the corresponding textile surface is subjected to steam.

The trough-shaped element 166 is designed such that the floor nozzle 32 can be inserted, in particular, with a cleaning cloth 34 arranged thereon. It is an applicability from above (in Figure 16 indicated by the arrow with the reference numeral 170) provided.

The floor nozzle 32 with possibly arranged cleaning cloth 34 is placed in an inner space 172 of the trough-shaped element 166.

The trough-shaped element 166 in this case has cover tabs 174, which are arranged so that when inserted bottom nozzle 32 these lock out in the direction 160 (upwards). There are further provided one or more locking elements 176, which are arranged in particular opposite to the one or more cover tabs 174, and which allow a locking in particular with the holding body 40. These also lock the removability upwards in the Direction 160. It can thus achieve a positive fixed arrangement of the holding body 40 in the interior 172 of the trough-shaped element 166. In one embodiment, a tab 178 is arranged on the trough-shaped element 166, which protrudes laterally.

An operator can step on the tab 178 and by appropriate force on the mop 24, the catch with the one or more locking elements 176 lift by pulling up in the direction 160 and then obliquely pull the bottom nozzle 32 from the trough-shaped element 166.

The mop 24 or the floor nozzle 32 functions as follows:

The floor nozzle 32 can be formed easily and with small height dimensions at least in the first area 66 and third area 70. It thus has a high maneuverability. The holding device 52 can be formed with low weight. The stop or stops 144 have a low mass.

In particular, a fixation of a cleaning cloth 34 on the holding body 40 in the direction 170 can be achieved by placing the holding body 40 with the holding device 52 on a correspondingly spread cleaning cloth 34.

The cleaning cloth 34 can be solved in a simple manner by an operator on the tab 158 and pulls the holding body 40 upwards.

The cleaning cloth 34 can be held without or only with slight sagging on the holding device 52, since over a large length in the width direction 58, a fixation is achieved. The stop or stops 144 have a large fixation length with respect to their total width as the sum of the individual widths.

Due to the ease of training and by the hinge device 94 with the pivot axes 96 and 98 (or 196 and 198) results in a movable floor nozzle 32. This has a high maneuverability. It has a lower ride height with respect to furniture.

The first spring device 108 or 208 and the second spring device 130 ensure that the holding body 40 is brought to the tube element 78 or 78 'in its respective basic position when there is no external application of force. To achieve this basic position then the weight of the holding body 40 is not necessary. Due to the defined basic positions with respect to the first pivot axis 96 or 196 and the second pivot axis 98 or 198, the holding body 40 can be easily connected to the cleaning cloth 34 or released from it. Furthermore, it is possible in a simple manner to connect or disconnect the floor nozzle 32 with the carpet slider 164.

For an operator, the mop 24 can be optimally positioned relative to a surface 180 to be cleaned (see Figure 2).

In Figure 2, an example is shown in which the rod 26 is disposed at an angle 162 to its normal position. This angle 182 corresponds to an angle between the first longitudinal axis 84 of the tubular element 78 in the position shown in FIG. 2 relative to the basic position relative to the second pivot axis 98. The position of the first longitudinal axis 84 in this basic position is indicated by reference numeral 184 in FIG indicated. (In the home position 184, the acute angle 90 exists between the first longitudinal axis 84 and the second longitudinal axis 88.) In Figure 3, the corresponding basic position with respect to the second

Swivel axis 98 shown. If, starting from the basic position according to FIG. 3, an operator pivots the tube element 78 relative to the holding body 40 about the second pivot axis 98, then the second spring device 130 exerts a restoring force.

In the position shown in FIG. 2, the holding body 40 with a cleaning cloth 34 arranged thereon remains at the transition from the basic position according to FIG. 3 to the position 180 shown in FIG.

FIG. 4 shows a further pivoting position of the tubular element 78 relative to the holding body 40. There is an angle 186 of the rod 26 with respect to the basic position (indicated by the reference numeral 184). The angle 188 between the stem 26 and the envelope plane 74 or surface to be cleaned 180 is the sum of the acute angle 90 and the angle 186.

FIG. 5 shows a position in which the tubular element 78 is in its basic position relative to the retaining body 40 relative to the first pivot axis 96. FIG. 5 shows a position in which the tubular element 78 is pivoted relative to the holding body 40 by a pitching motion about the first pivot axis 96.

In this position, the first spring means 108 exerts a restoring force, which endeavors to restore the basic position.

The first spring device 108 comprises a torsion spring 114 in the exemplary embodiment shown. In the embodiment of the first spring device 208, a spiral spring 210 is provided with a slotted guide via a link element 206 and counter element 214, which exerts a restoring force between the second tube piece 202 and the first tube piece 204 relative to the first pivot axis 196 and strives to this in their relative basic position to each other to lead.

According to the invention, a floor nozzle 32 is provided, via which a held cleaning cloth 34 can be acted upon with fluid and in particular with steam. The floor nozzle 32 has over the joint device 94 extensive movement options; the tubular element 78 or 78 'can be flexibly positioned with respect to the holding body 40; Thus, the holding body 40 and a cleaning cloth 34 held on it can be flexibly positioned with respect to the tubular element 78 or 78 '. This results in a high maneuverability with advantageous driving under possibilities and the like.

By the provision of the first spring means 108 and 208 and the second spring means 130 basic positions of the holding body 40 to the tube member 78 and 78 '(and thus to the handle 26) are achieved in an automatic manner, when a corresponding external force influence is eliminated. The floor nozzle 32 can be easily formed and produced with low material costs.

This results in a simple structural design. In particular, the T-piece 122 of the fluid distributor 120 or 220 forms a hinge part of the second articulation 118 and in particular a shaft of the second articulation 118. LIST OF REFERENCE NUMBERS
