Description

Floor nozzle for hard floors

The present invention relates to a novel floor nozzle for hard floors.

Hard floors and their care play an ever-increasing role. The known wiper systems available on the market to date are mechanical systems that can be used exclusively for one operation namely the wet wiping of a hard floor. All of these wiper systems have in common that prior to their use the coarse dirt is mixed with another auxiliaries, such as e.g. must be removed with soap / scoop or a vacuum cleaner.

On the other hand, with a vacuum cleaner with hard floor nozzle probably dry dust and coarse dirt are absorbed; however, a wiper system is necessary for removing dried-on dirt or for wet cleaning.

A suitable for the work sucking and wiping floor nozzle for hard floors is known for example from WO 02/085174 A1. The vacuum cleaner mouthpiece described has a plate with a bottom, which rests on a floor. The plate carries a wiper. The wiping means is arranged between two suction channels, which are connected to a suction pipe of a vacuum cleaner. In what way a humidification of the wiper can be realized, is not explained in detail.

On this basis, the present invention has the object to provide a comparison with the prior art improved soil care products.

This object is achieved by a floor nozzle for hard floors, in which the work suction and wiping are combined and a uniform moisturization of the wiper is guaranteed.

The floor nozzle for hard floors, which is designed to be suitable for the work of sucking and wiping, has for this purpose a moisture transfer device connected to a liquid supply device with a wiping medium carrier for holding a moisture transfer device to be applied and nachbefeuchtenden towel on. The liquid supply device comprises at least one liquid tank in which water or another cleaning liquid is stored. At least the liquid tank is integrated in the floor nozzle. The liquid supply device preferably also comprises a liquid pump. The moisture transfer device serves to distribute the liquid provided by the liquid supply device uniformly over a surface, so that a wiper agent is uniformly soaked with liquid. The wiper may be a wipe. Because the liquid supply device and the moisture transfer device are integrated, the floor nozzle according to the invention can be used autonomously for the wet cleaning of hard floors. For example, a vacuum cleaner pipe can be connected to the floor nozzle and simultaneously wiped and vacuumed. On the other hand, only a guide stem can be connected to the floor nozzle according to the invention and the floor nozzle can thus be used as a wet mop. Overall, the floor nozzle according to the invention is characterized very variable and versatile.

In this case, the wiping agent carrier for holding the wiping cloth on the underside of the wiping medium carrier may be formed in a position of the wiping cloth adjacent to the moisture transfer device. The mop carrier forms a support surface for the wiper or the wipe, so that the wipe evenly flat and smooth without drapery can rest on the bottom of the floor nozzle and an optimal dampening result is achieved on hard floor. At the same time, the wiping agent carrier can serve as a counter-hold to fix the ends of the wipe and to keep attached to the floor nozzle. This achieves a secure and functionally optimized holder for the wiping agent on the floor nozzle.

Preferably, the wiping agent carrier may have clamping strips for holding the edge sections of the wipe in a position of the wipe lying flat against the bottom nozzle of the wiping medium carrier. The terminal strips preferably fix the ends of the wipe to the floor nozzle or the wiping agent carrier. By using terminal strips, the wipes can be easily and quickly fixed and released again from the floor nozzle. This facilitates handling for a user. In one embodiment of the invention, the floor nozzle may have a connection joint with a receiving socket for a suction line, which is designed to carry out an adjusting movement for opening and closing the terminal strips. The connection joint according to the invention has all known from conventional vacuum cleaner functionalities. As an additional functionality according to the invention, the connection joint forms an actuating element for opening and closing the holder for the wiper, ie the wipe. Thus, by simply pressing a vacuum cleaner pipe connected to the floor nozzle or a guide stem of a mop, the clamp can be released or locked. This has the advantage that the user does not have to stoop to open and loosen the wipe to the floor nozzle, but relaxed while standing can loosen or fix the holder for the wipe.

Preferably, the terminal strips are connected to Saugkanalmundstücken, which are mounted to open and close the terminal strips adjustable on the floor nozzle. Due to the adjustability of the Saugkanalmundstücke the Saugkanmundmundstücke are in the moment in which the wipe to be attached to the floor nozzle pivoted outwardly, so that even with a further suction operation pending on the Saugkanalmundstücken suction air flow does not interfere with the attachment of the wipe. At the same time the weggeschwenkten Saugkanalmundstücke form pincer-like gripping elements, which is able to grab a wiping flat on the floor at the opposite end and is able to introduce in Klemmfugen, which are arranged between the terminal strips and the wiper means carrier. Thus, the wipe laid flat on the floor is automatically fixed to the floor nozzle by means of the clamping strips.

The moisture transfer device may be made of a material containing capillary for distributing liquid from the liquid supply device. The capillaries have the function to distribute the liquid provided by the liquid supply device only selectively over a surface as evenly as possible. The capillaries form flow channels in which the liquid is passed on without the need for additional external delivery. The capillaries can be designed to supply the wipe uniformly with liquid. Preferably, the moisture transfer device is made of an open-pored sponge-like material. In open-pore spongy materials capillaries are already integrated in sufficient quantity and very evenly distributed. So no capillaries must be introduced by separate manufacturing processes.

The liquid supply device is integrated in an advantageous embodiment in the floor nozzle. This creates a very self-sufficient wet cleaning device. It also eliminates additional interconnections that would have to be connected by the user and could interfere during operation. Thus, the use of the floor nozzle according to the invention is facilitated.

In any embodiment, the liquid supply device may have a pump for transporting the liquid from a liquid tank to the moisture transfer device which transports a quantity of liquid corresponding to the frequency of movement of the floor nozzle. In this case, the pump is preferably designed so that a variable amount of liquid is conveyed to the wipe and that in many wiping movements more liquid is conveyed to the wipe than with very few wiping movements. If the floor nozzle is not in motion, there is no delivery of liquid at all, and consequently the wipe can not be soaked at standstill.

The nozzle according to the invention is particularly suitable for commercial vacuum cleaner floor. However, it can also be used without a vacuum cleaner, as a tank is advantageously integrated in the nozzle.

Additional details and further advantages of the invention will be described below with reference to the variants exemplified in the schematic drawings. The hard floor nozzle has two suction channels, between which at least one wiper, in particular a wiper and / or a mop and / or a sponge, is attached. The wiping agent is preferably rewetted with water continuously, in particular via a sponge, in order to have a constant moisture on the wiping agent and thus to allow the wiping agent to remain at the nozzle for a longer time, without having to remove and rewet the wiping agent. The features disclosed in the foregoing description, the claims and the drawings may be of importance both individually and in any combination for the realization of the invention in its various forms.

An embodiment of the invention is described with reference to a floor nozzle exemplified in the figures.

Figure 6 is a view in cross section with the terminal strips in an open position according to Figure 5;

Figure 7 is a view in cross section with the terminal strips in a closed position according to Figure 4;

A floor nozzle according to FIG. 1 has a housing shell 1. This housing shell 1 is formed with a rectangular contour. Adjacent to two opposite longitudinal sides of the housing shell 1 are a front in the sliding direction of the floor nozzle, shown in Fig. 1 left Saugkanalmundstück 2 and in the sliding direction of the floor nozzle behind, in Figure 1 right illustrated Saugkanalmundstück 3 on the Bo stored dendüse. The front Saugkanalmundstück 2 and the rear Saugkanalmundstück 3 are pivotally mounted in the arrow direction on the floor nozzle. At the floor nozzle, a wiping agent carrier 4 is attached. At the bottom of the wiper support 4 is a wipe 5 at. In the illustrated, attached to the wiper support 4 position of the wipe 5 are the front Saugkanalmundstück 2 and the rear Saugkanalmundstück 3 in a closed position in which the wipe 5 is held flat against the underside of the wiper support 4. In the illustrated closed position of the Saugkanalmundstücke 2 and 3, the opposite longitudinal edge portions 6 and 7 of the wipe 5 are clamped in a front clamping gap 8 and a rear nip 9 fixed to the floor nozzle.

A liquid supply device 50 has a liquid tank 11. The liquid tank 1 1 is detachably held on the floor nozzle. On the liquid tank 1 1, an elastic detent spring 12 is fixed, which has a handle portion 13. The handle portion 13 is formed integrally with the detent spring 12. The detent spring 12 is made of plastic and molded directly to the liquid tank 1 1. The detent spring 12 holds the liquid tank 1 1 fixed in a latched position on the floor nozzle. In addition, a filling opening 14 of the liquid tank 1 1 is closed by a lid 15 by means of the detent spring 12.

The floor nozzle is connected via a connection joint 16 with a receiving socket 17 for a suction pipe of a vacuum cleaner. The connection joint 16 is formed by a joint socket 18 and a joint ball 19. The joint socket 18 is provided in the floor nozzle and the joint ball 19 is connected to the receiving socket 17. The connection of the joint ball 19 to the receiving socket 17 is designed as a snap-locking connection 20. The snap-locking connection 20 is not rigid, but has a degree of freedom, so that the receiving socket 17 is rotatably mounted with respect to the joint ball 19 about a coaxial with the receiving port 17 extending axis of rotation 21. To realize this rotation about the axis of rotation 21, the receiving socket 17 has a plurality of circumferentially spaced inwardly directed latching hooks 22, which engage in an outwardly directed circumferential latching groove 23 at a connection 24 of the joint ball 19. Fig. 2 shows the floor nozzle of Fig. 1 with removed liquid tank 1 1. In the housing shell 1 of the floor nozzle a receiving recess 49 for the liquid tank 1 1 is provided. The receiving recess 49 is integrally formed in the housing shell 1 of the floor nozzle. A liquid supply device 50 integrated into the floor nozzle has a connection connection 51, which is connected to a delivery line 52. The connection connection 51 has a hollow cylindrical dome 53, at the upper end of which a hollow needle valve 54 is arranged. Via an opening provided at the free end of the hollow needle valve 54, liquid is sucked from the liquid tank 11 (FIG. 3), which liquid flows through the hollow cylindrical dome 53 into the delivery line 52. The negative pressure for the suction of liquid from the liquid tank 1 1 is generated by a pump 100, which is connected to the delivery line 52.

The pump 100 is designed as a diaphragm pump and inserted into a pump chamber 55 in the floor nozzle. The pump chamber 55 is formed integrally with the housing shell 1. The pump 100 has a deflectable membrane 101 which can be activated by a ball 102 movably mounted in the floor nozzle. Due to a deflection of the membrane 101, a defined amount of liquid is pumped by the pump 100. The ball 102 is in a direction free rolling in a groove 103 of the floor nozzle. The channel 103 is integrally formed on the housing shell 1 of the floor nozzle. The curvature of the channel 103 is adapted to the diameter of the ball 102, so that the ball 102 is guided in the channel 103 and a lateral deflection of the ball 102 is limited. The channel 103 extends substantially in the sliding direction of the floor nozzle, so that the ball 102 is guided on a path on which the ball 102 can move freely in the sliding and pulling direction of the floor nozzle within a distance. The movement of the ball 102 along the path of the channel 103 is induced in a forward or backward movement of the floor nozzle in the sliding direction or pulling direction due to the inertia of the ball 102. In a backward movement of the floor nozzle, the ball 102 at the front end of the distance of the channel 103 to the membrane 101 of the pump 100 so that the membrane 101 is set in motion and due to their deflection movement of a defined amount of liquid from the feed line 52 to a moisture transfer device 150 (Fig. 4) is transported. With a forward movement of the floor nozzle, the ball 102 moves away from the diaphragm 101 of the pump 100 and the membrane 101 can return to its original position. At her Moving back to the starting position, a negative pressure is generated in a pump chamber 14 of the pump 100, which draws in a quantity of liquid from a supply line 104.

In Figure 3, the liquid tank 1 1 is shown. The liquid tank 1 1 has a chamber 26 for storing liquid. The chamber 26 is substantially parallelepiped-shaped and has an upper ceiling wall 27, a lower bottom wall 28 and four side walls 29 in the ceiling wall 27, the filling opening 14 is introduced. The filling opening 14 is closed by the lid 15. Between filling opening 14 and lid 15, a sealing seal 30 is interposed. The closure seal 30 is attached to the lid 15, for example. The lid 15 is releasably secured by means of a detent spring 12 to the liquid tank 1 1. A release of the lid 15 from the liquid tank 1 1 takes place by pivoting the detent spring 12 laterally outwardly from the lid 15. A manual pivoting of the detent spring 12 is facilitated by the handle portion 13 which is integrally formed on the detent spring 12, so that an actuation of the handle portion 13 transmits to the detent spring 12 and this can be pivoted to release the detent connection to the cover 15 ,

In the lower bottom wall 28 of the chamber 26, a bush-shaped recess 31 is formed, which is adapted in shape and size to the dome 53 of the liquid supply device 50 in the housing shell 1 such that the sleeve-shaped recess 31 in the installed position of the liquid tank. 1 1 in the floor nozzle precisely over the dome 53 inverts. A spout 32 corresponding to the hollow needle valve 54 of the housing shell 1 is equipped with a discharge opening 33. At the discharge opening 33, a sealing valve 34 is attached. In the inserted into the floor nozzle position of the liquid tank 1 1, the hollow needle valve 54 of the housing shell 1 penetrates into the sealing valve 34 of the discharge opening 33 at the outlet 32, so that the outlet 32 is opened and liquid from the liquid tank 1 1 via the outlet 32 and the connection connection 51 on the housing shell 1 in the conveying line 52 of the liquid supply device 50 can be conveyed out. The drain opening 33 is located near the upper end of the height of the liquid tank 1 1, so that when removed liquid tank 1 1 no or only a small liquid column is present at the closed drain opening 33. So that during operation of the floor nozzle as far as possible, the entire liquid content from the liquid tank 1 1 abge- can be pumped, the drain opening 33 is connected to a suction line 35, the free intake opening 36 extends close to the lower bottom wall 28 of the liquid tank 1 1.

The liquid tank 1 1 is integrated into a design panel 37 of the floor nozzle. The design panel 37 is cupped and adapted in shape and size to the shape of the floor nozzle. The design panel 37 extends over approximately the entire width of the floor nozzle. The design panel 37 has a collar cutout 38, which is cut out of the design panel 37 as an open-sided cutout with an arcuate contour. In the covered position of the design panel 37 on the floor nozzle, the contour of the joint ball 19 of the connection joint 16 can emerge from the nozzle plane via the collar cutout 38. About the collar cutout 38 with one-sided open cutout and arcuate contour a waisted constriction is created in the design panel 37, which forms a handle 39 for the liquid tank 1 1. A window cutout 40 for a viewing window 41 is introduced at an end of the design panel 37 opposite the liquid tank 1 1. The window opening 40 is cut out as a one-sided open cutout in the design panel 37. The inserted window 41 allows in the installed position of the design panel 37 in the floor nozzle an insight on the underlying pump 100 and the ball 102nd

In Fig. 4, the floor nozzle of Fig. 1 is shown in a perspective view. The floor nozzle is shown with the housing shell 1 removed. At the front Saugkanalmundstück 2 a first terminal block 200a is attached. At the rear Saugkanalmundstück 3, a second terminal block 200b is attached. Both terminal strips 200a and 200b are in a closed position, in which the opposite longitudinal edge portions 6 and 7 of the wipe 5 are clamped to the wiper means carrier 4. The clamping of the opposite longitudinal edge portions 6 and 7 takes place between the wiper means carrier 4 and in each case one clamping bars 200a, 200b. The attached to the Saugkanalmundstücken 2 and 3 terminal strips 200a, 200b can be swung out with this, as indicated in Figure 1 by the arrow in an open position. The terminal strips 200a, 200b in the open position are explained in more detail with reference to FIG. For a pivotable mounting of the terminal strips 200a and 200b and the Saugkanalmundstücke 2 and 3, these holding arms 201 a and 201 b on. Each clamping strip 200a, 200b or each Saugkanalmundstück 2, 3 preferably has two holding arms 201 a, 201 b on. Each holding arm 201 a, 201 b extends from the Saugkanalmundstück 2, 3 in the region of a Haltearmansatzes 214 a, 214 b in a direction obliquely upward and then passes into a central Haltearmabschnitt 215 a, 215 b, which aligned in the closed position substantially horizontally is. At its projecting Haltearmende 216 a, 216 b are each a guide pin 202 a, 202 b attached. Each guide pin 202a, 202b extends at a right angle to the longitudinal extent of the support arms 201 a, 201 b and points inwards in the direction of an associated guide slot 203 a, 203 b. The guide slots 203a, 203b are arranged on a hood 155 of the central plate 154 and preferably formed integrally therewith. In the closed position shown in FIG. 4, the guide pins 202a, 202b are located at an inside upper end within the guide slot 203a, 203b. Consequently, the holding arms 201 a, 201 b can not only rotate about the axis of the guide pins 202 a, 202 b, but are longitudinally displaceably guided along a translatory path along the guide slot 203 a, 203 b. At a distance from the guide pins 202a, 202b, a pivot pin 217a, 217b is arranged obliquely below the guide pins 202a, 202b in FIG. Between the guide pins 202a, 202b and the pivot pins 217a, 217b there is a respective slide track 218a, 218b of an intermediate lever 204a, 204b. The slideways 218a, 218b are cam-shaped to the intermediate lever 204a, 204b formed and have a T-shaped cross section, by means of which the holding arms 201 a, 201 b are guided on both sides, so that they can perform a reciprocating pivoting movement which the terminal strips 200a, 200b and the Saugkanalmundstücke 2, 3 between the closed position of FIG. 4 and the open position of FIG. 3 can be moved back and forth. To carry out its own pivoting movement, the intermediate levers 204a, 204b each have a bearing eye 219a, 219b. Each bearing eye 219a, 219b is attached to a hinge pin 220a, 220b, so that the intermediate levers 204a, 204b are rotatably mounted about an axis of the hinge pins 220a, 220b. The hinge pins 220a, 220b are provided on the central plate 154 and preferably formed directly on it. Each two intermediate levers 204a, 204b are pivotally mounted mirror-symmetrically to each other and thereby perform a scissor-like synchronous movement. This scissor-type synchronous movement is triggered by a driver 205 which is fixed to a pressure plate 221, which from an upper position, as shown in Fig. 4 in a lower position, as shown in Fig. 5 in a vertical direction back and forth is mobile. To the pressure plate 221, a lower movable joint half 18b of the joint cup 18 is formed. The joint pancreas Nine half 18b carries the joint ball 19 of the connection joint 16. Due to the coupling elements just described can be pivoted by pressing the connection joint 16 attached to the Saugkanalmundstücken 2 and 3 terminal strips 200a, 200b from a closed position to an open position. The coupling elements thus consist in the embodiment shown of the joint ball 19 of the connection joint 16, the pressure plate 221 with the lower movable joint half 18b and the driver 205, and the intermediate levers 204a, 204b and the holding arms 201 a, 201 b. Thus, the terminal strips 200a, 200b are held in the closed position under spring bias, a torsion spring 206 is inserted between the two each mirror-symmetrically mounted to each other pivotally mounted intermediate lever 204a, 204b. The torsion spring 206 has a helical torsion spring coil 222 to which two wire legs 223a, 223b connect, at the ends of which is a perpendicular bent spring hooks 224a, 224b. Each spring hook 224a, 224b engages a hook eye 225a, 225b at an upper end of each intermediate lever 204a, 204b. By means of the torsion spring 206, the hook eyes 225a, 225b spread apart, so that the intermediate lever 204a, 204b are forced into their scissor-like closed position. At the opposite ends of the intermediate levers 204a, 204b, the end-side forceps syringes 226a, 226b bear against a stop cam 227 in the closed position. The stop cam 227 is formed directly on the central plate 154.

In Fig. 5, the floor nozzle of Fig. 1 is shown in a perspective view. The floor nozzle is shown with the housing shell 1 removed. Both terminal strips 200a and 200b are in an open position, in which the opposite longitudinal edge portions 6 and 7 of the wiping means 5 are exposed and the wiping agent can be detached from the wiping means carrier 4. The clamping strips 200a and 200b, which are in the open position, are pivoted outward via the suction channel mouthpieces 2 and 3 pivoted upwards. The holding arms 201 a, 201 b are rotated in a clockwise direction relative to the position shown in FIG. 4 and are positioned offset from the position shown in FIG. 4 downwardly and outwardly. This offset position is achieved via the translational movement which is guided by the guide slot 203a, 203b. In Fig. 5 it can be seen how the guide pins 202a, 202b of the support arms 201 a, 201 b in the guide slot 203 a, 203 b is offset obliquely downward and a portion of the channel 228 of the guide slot 203 a, 203 b releases. The pivoting of the holding arms 201 a, 201 b is triggered by the scissors-like intermediate lever 204 a, 204 b, the mit- Tels of their bearing eye 219 a, 219 b pivoted to the hinge pin 220 a, 220 b of the central plate 154 are pivoted outwardly. In this case, the slideways 218a, 218b cam-like the holding arms 201 a, 201 b at their pivot pins 217a, 217b apart. The scissor-type intermediate levers 204a, 204b are opened by the downwardly driven driver 205. In FIG. 5 it can be seen that the driver 205 is mounted in a driver guide 229 which permits a vertical movement of the driver 205. The driver guide 229 is inserted in the hood 155 of the central plate 154 as a vertical slot. Through the vertical slot of the driver guide 229 protrudes a connecting member 230 which connects the driver 205 with the lower movable joint half 18 b of the joint cup 18. It can be seen that the ball 19 of the connecting joint 16 is located in a lower position in relation to the closed position shown in FIG. 4 in the open position shown in FIG. 5 than in FIG. By comparing FIGS. 2 and 3, it can be seen that, by pressing down the connection joint 16, the terminal strips 200a and 200b are pivoted into the open position, in which they release the wiping means 5. The torsion spring coil 222 of the torsion spring 206 supports on the top of the stop cam 227.

In Fig. 6, the floor nozzle is shown in a view in cross section with the clamping bars 200a and 200b in an open position shown in FIG. The connection joint 16 with the receiving socket 17 has already been described in detail to Fig. 1. In the following, the features provided for the functions that allow or prevent opening or closing of the clamping bars 200a, 200b will be explained, as well as the locking of the clamping bars 200a, 200b in an open position.

Fig. 6 shows the connection joint 16 in a position in which the terminal strips 200a, 200b are pivoted into the open position, so pivoting of the terminal strips 200a, 200b is allowed. The connection joint 16 has the joint ball 19. The hinge ball 19 is supported between the lower movable hinge half 18b and the upper fixed hinge half 18a provided on the shell 1 of the housing. By means of the joint pan halves 18a and 18b, the connection joint 16 is tiltably and pivotably mounted on the floor nozzle. Due to the lower movably mounted hinge half 18b, the connection joint 16 can also be pressed down in a vertical direction. By pressing the connection joint 16 downward, the terminal strips 200a, 200b are pivoted to the open position. The lower movable Joint half 18b has for this purpose a window opening 207, through which a projection 209 can penetrate. On the inner bottom side 208 of the mop head, the projection 209 is arranged. The pressing of the connection joint 16 is permitted in the orientation of the connection joint 16 shown in FIG. About a alignment corresponding to this recess 210 at the connection joint 16 of the projection 209 penetrates in the depressed position of the connecting link 16 as shown.

The connection joint 16 is locked in the lower position shown by a pivoting movement, as shown in FIG. 6 counterclockwise. This pivotal movement is possible only in the depressed position of the connecting joint 16. In the latched position, the terminal strips 200a, 200b are in the open position shown. For latched holding the terminal strips 200a, 200b in the open position, arranged on the inner bottom side 208 of the mop head projection 209 has a Vorsprungsrastnase 21 1, which engages in the depressed and pivoted position of Anschlu ßgelenkl 6 an undercut 212 at the connection joint 16.

The projection 209 disposed on the inner bottom side 208 of the wiping head strikes against the press-preventing alignment of the guide means at the terminal joint so as to prevent the movement of the connecting link 16 from occurring and not open the terminal bars 200a, 200b. If the joint ball 19, for example, pivoted very far in the clockwise or counterclockwise direction relative to the position shown in FIG. 6, the recess 210 on the connection joint 16 is no longer in alignment with the window opening 207 and the projection 209. If the connection joint 16 is then pressed downwards , hits a closed surface of the joint ball 19 on the top surface 231 of the projection 209 and the connection joint 16 can not be moved further down. In a pending on the top surface 231 of the projection 209 position of the connection joint 16, the terminal strips 200a, 200b are still in the closed position in which the wiper means 5 is held on the wiper means carrier 4.

In Fig. 7, the closed position in which the wiper means 5 is held on the wiper means carrier 4 is shown. The clamping bars 200a, 200b have gripping ribs 213a and 213b, which, when moved from the open position of the clamping bars 200a, 200b, slide over the bottom into a closed position and a wiping means 5 placed on the bottom at the edge portions 6 and 7 engages, zusammenrafft and pulls into the clamping gaps 8 and 9 until the edge portions 6, 7 between the wiper means carrier 4 and the terminal strips 200a, 200b supporting Saugkanalmundstücken 2 and 3 are clamped. Depending on a sealing lip 65a and 65b is inserted between the wiper means carrier 4 and the Saugkanalmundstück 2 and the Saugkanalmundstücken 3. Each sealing lip 65a and 65b separates the negative pressure area of the suction channel mouthpieces 2 and 3 from the wiping means 5, so that the moisture is not directly sucked out of the wiping means 5 without moistening the floor. At the same time, the sealing lips 65a and 65b act as scratches that can slide over the floor and release settled dirt. Preferably, the sealing lips 65a and 65b to increase the sealing and cleaning effect as double lips, as shown in Fig. 7, formed.
