Description

Floor nozzle for hard floors

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

A suitable for the work sucking and wiping trained floor nozzle for Hartbö- 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. Velcro fasteners are provided for fastening the wiper agent to the wiper agent carrier. If the cleaning agent is completely soiled, removal of the used wipe is only possible with great effort and in an unpleasant manner.

On this basis, the present invention has the object to provide a comparison with the prior art improved disposal for the wiper.

This object is achieved by a floor nozzle for hard floors, which has at least one suction nozzle and a wiper agent carrier with a holder for a wiper, and a release agent, which is designed for releasing a wiper agent held on the wiper agent during suction. In that the fixed wiper, which is preferably a wipe, can be solved by the release means in a simple manner, a manual release is no longer required. A wiping agent dissolved via the release agent can be sucked in in a simple manner via the floor nozzle.

Preferably, the release means is a mechanism for releasing the wipe from the wiping means carrier. The release means may have an actuating element for opening the closed holder. In one embodiment of the invention, the release means can be formed by the connection joint of the floor nozzle, which is designed to carry out an adjusting movement for opening and closing of terminal strips. The connection joint according to the invention has all known from conventional vacuum cleaner functionalities. As an additional functionality of 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 tube connected to the floor nozzle or a guide stem of a mop, the clamping can be released. 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.

Preferably, the release means for allowing a transport of the dissolved wiping cloth is formed under the suction nozzle during a sliding movement of the floor nozzle. By pivoting the terminal strips connected to the suction channel mouthpieces, the ends of the wipe are released so that the wipe is wound up during a sliding movement of the floor nozzle usual for vacuuming and can be sucked in via one of the suction channel mouthpieces. This has the advantage that a soiled wiping cloth no longer has to be touched by the user. In addition, the user no longer has to stoop to the floor nozzle to remove the soiled wipe. It is sufficient to actuate the release agent in a relaxed attitude and a short sliding movement of the floor nozzle, as usual when vacuuming, and the wipe is sucked in through the vacuum cleaner and disposed of.

In an advantageous embodiment of the invention, the suction mouthpiece for storing a sucked wipe is connected to a wiper storage. So the Vacuum cleaner bag of the vacuum cleaner is not unnecessarily burdened with the wipe, a separate container may be provided for the soiled dirty wipes. This container may be integrated according to the invention in the floor nozzle. Alternatively, the Wischtuchspeicher may be a separate container, for example, on a suction pipe of the vacuum cleaner. Preferably, the container is arranged on a guide device of the floor nozzle, in particular on a suction pipe connected to the floor nozzle of a vacuum cleaner.

Instead of a separate container but also the existing dust bag of the vacuum cleaner can be used as Wischtuchspeicher. In this embodiment, a comminution device for the sucked-in wipe can optionally be interposed between the suction mouthpiece and the wiper-tip storage. By shredding the wipe, very small particles are generated from the wipe. This reduces the risk that the wipe can clog the suction tube, a suction hose or the area of the dust bag inlet. As a result of comminution, more wipes can also be introduced into the dust bag or the separate container than would be possible with uncut wipers.

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.

Show it:

Figure 2 is a perspective view from above of the floor nozzle of Figure 1 with removed housing shell with terminal strips in a closed position. - A -

Figure 3 is a perspective view from above of the floor nozzle of Figure 1 with removed housing shell with terminal strips in an open position.

In Fig. 1, a floor nozzle according to the invention is shown connected to a vacuum cleaner 149. The vacuum cleaner 149 has a dust bag 96 which receives dust sucked in through the floor nozzle. The vacuum cleaner 149 is connected via a suction pipe 95 with a receiving socket 17 of a connection joint 16 of the floor nozzle. Between the receiving port 17 and the suction tube 95, a crushing device 94 is interposed. The optionally interposed crushing device 94 serves to shred a soiled wipe 5 received from the floor nozzle into small pieces, which can then be transported via the suction pipe 95 into the dust bag 96 of the vacuum cleaner 149 by means of the suction air stream as a carrier medium. Alternatively or in addition to the dust bag 96, a separate container 97 can be provided, can be spent in the pieces of the wipe 5 or the entire one-piece wipe 5 on the suction air stream. The separate container 97 is attached to the suction tube 95 of the vacuum cleaner 149 in the example shown.

The floor nozzle according to FIG. 1 has in detail 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 in the sliding direction of the floor nozzle front, shown in Fig. 1 left Saugkanalmundstück 2 and in the sliding direction of the floor nozzle behind, shown in Figure 1 right Saugkanalmundstück 3 are mounted on the floor nozzle. 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. On the underside of the wiper support 4, a wipe 5 is applied. In the illustrated, attached to the wiper support 4 position of the wipe 5, the front Saugkanalmundstück 2 and the rear Saugkanalmundstück 3 are in a closed position in which the wipe 5 is held flat against the underside of the wiper support medium 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.

In Fig. 2, 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 Saugkanal- mouthpiece 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 strips 200a, 200b simultaneously form the release means 98 according to the invention. The clamping of the opposite longitudinal edge sections 6 and 7 takes place between the wiping means carrier 4 and in each case one clamping strip 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 terminal strip 200a, 200b or each Saugkanalmundstück 2, 3 preferably has two holding arms 201 a, 201 b. 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 holding arms 201a, 201b and points inwards in the direction of an associated guide slot 203a, 203b. 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. 2, 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 motion through which the Clamping strips 200a, 200b and the Saugkanalmundstücke 2, 3 between the closed position of Fig. 2 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 mounted on 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-like synchronous movement is triggered by a driver 205 which is attached to a pressure plate 221, the an upper layer, as shown in Fig. 2 in a lower layer, as shown in Fig. 3 is reciprocally movable in a vertical direction. To the pressure plate 221, a lower movable joint half 18b of the joint cup 18 is formed. The Gelenkspfannenhälfte 18b carries the joint ball 19 of the connection joint 16. Due to the coupling elements just described can be pivoted by pressing the connecting joint 16 attached to the Saugkanalmundstücken 2 and 3 terminal strips 200a, 200b from a closed position to an open position. The connection joint 16 simultaneously forms the actuating element 99 according to the invention, which releases the wipe, so that it can be sucked in, for example, by the vacuum cleaner 149 of FIG. The coupling elements, which form a mechanism for releasing the wipe 5 from the mop carrier 4, thus consist in the embodiment shown of the joint ball 19 of the connection joint 16, the pressure plate 221 with the lower movable hinge half 18 b and the driver 205, and the intermediate levers 204 a, 204b and the holding arms 201a, 201b. 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. 3, the floor nozzle of Fig. 1 is shown in a perspective view. The floor nozzle is shown with the housing shell 1 removed. Both clamping strips 200a and 200b are in an open position, in which the opposite longitudinal edge sections 6 and 7 of the wiping means 5 are exposed and the wiping agent can be released from the wiping means carrier 4. The terminal strips 200a and 200b, which are in the open position, are swung out via the suction channel mouthpieces 2 and 3 which are pivoted upwards. The holding arms 201 a, 201 b are opposite to that shown in Fig. 2 Turned clockwise position and positioned offset from the position shown in Fig. 2 down and out. This offset position is achieved via the translational movement which is guided by the guide slot 203a, 203b. In Fig. 3 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 scissor-like opened intermediate lever 204a, 204b, which are pivoted by means of their bearing eye 219a, 219b to the hinge pin 220a, 220b of the central plate 154 outwardly pivoted. 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. 3 it can be seen that the driver 205 is mounted in a driver guide 229, which allows 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 joint ball 19 of the connection joint 16 with respect to the closed position shown in FIG. 2 in the open position shown in FIG. 3 is in a lower position 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.
