Description

 Cleaning device with a rocker driven by a motor  

The invention relates to a cleaning device, in particular for a wet cleaning device, having a motor-driven rocker plate and a carrier plate for accommodating the cleaning element that can be connected to the rocker plate, wherein, in the connected state The rocking plate and the carrier plate have corresponding arrangement means on the side of the plate facing each other, wherein the arrangement means of the carrier plate and the arrangement means of the rocking plate constitute a pair of arrangement means, wherein the first arrangement means the opposite board The swaying plane is constructed to be free of play, and the second arranging means is parallel to its swaying plane and has only a moving gap along the direction of motion predetermined by the second arranging means.

Furthermore, the invention relates to a wet cleaning device having such a cleaning device.

Cleaning devices of the foregoing type as well as wet cleaning devices are known in the prior art.

Such cleaning devices are used in particular for the cleaning of hard floor coverings, for example tile floors or parquet floors, in particular in the domestic sector. The cleaning device can, for example, be constructed as an add-on for establishing a releasable connection with the basic device. In particular, the basic device provides means for moving the cleaning device over the surface to be cleaned, a power source, and optionally a suction fan or the like. The cleaning device has a cleaning element that acts on the surface to be cleaned, for example in the form of a fabric cleaning cloth. The movement of the cleaning element is effected by rocking the plate, wherein the movement (forward and retraction) carried out by the user of the cleaning device during the conventional cleaning operation is caused by the movement of the rocker and thus by the movement of the cleaning element. Superimposed. The cleaning element is fixed to the carrier, and the carrier can be placed on the rocker such that the carrier is fixedly coupled to the rocker and the rocking motion is performed together. For example, the electric eccentric drive is used to rotate the rocker.

The publication EP 2 578 131 B1 discloses, for example, a cleaning device of the aforementioned type. In order to arrange the carrier plate together with the cleaning elements arranged thereon on the rocker plate, the carrier plate and the rocker plate have corresponding fixed tracks.

DE 10 2010 000 378 A1 discloses a floor wiping device with a motor-driven rocker that secures the carrier for the cleaning element to its rocker. The rocking plate and the carrier plate have corresponding arrangement means, and the arrangement means can be combined in pairs. Wherein, the first arrangement means of the carrier board is different from the second arrangement means of the carrier board. The two arrangement means of the rocker are also different from each other.

A disadvantage of the cleaning device disclosed in the prior art is that in order to secure the carrier, the user must be aware of the preset orientation of the placement means on the carrier.

In view of the above, based on the above prior art, it is an object of the present invention to provide a cleaning apparatus which does not have the aforementioned disadvantages.

In order to achieve the above object, the present invention proposes two arrangement means of the rocking plate and/or two similar arrangement means of the carrier plate, which are point-symmetric relative to the rotation axis of the carrier plate or the rocking plate. Constructed and arranged by the housing.

According to the invention, two identical arrangements of the rocker and/or two similar arrangements of the carrier are constructed and arranged point-symmetrically with respect to the axis of rotation of the carrier or rocker. Through this technical solution, the engagement of the carrier and the rocker is particularly convenient for the user. That is, the carrier and the rocker are applied such that they have two mounting positions that are likely to rotate 180 degrees from each other. Therefore, it does not matter whether the user fixes the carrier on the rocker in the first orientation or in an orientation that is rotated by 180°.

The carrier is disposed on the rocker by two separate positioning means, wherein the first means provides a substantially gap-free connection, and wherein the second means can be parallel to The direction of the plane is swung to create a motion gap. In this case, when the carrier plate is arranged on the rocker plate, on the one hand, the carrier plate can be oriented relative to the rocker plate, on the one hand, the carrier plate can be attached to the rocking plate with approximately no play. In particular, it is also possible to achieve the engagement and separation of the two plates with a small force by the second arrangement means. The second arrangement means that the pair is transmitted through the available motion gap to achieve a particularly simple engagement without the need to compress, for example, an elastomer assembly or the like. The first arrangement of the gap-free arrangement prevents the carrier plate from undergoing a translational movement associated with the movement of the carrier plate against the rocking plate in a plane parallel to the rocking plane, so that in principle only the second arrangement can be surrounded. A rotational motion occurs at the center of the dual. However, by the second arrangement means dual, the rotational movement of the motion gap is prevented only in the direction of motion that deviates from the rotational motion trajectory. Therefore, all of the motion schemes for the carrier plates connected to the rocker plate in the plane parallel to the rocking plane of the rocker or carrier are blocked. The connection of the rocker plate to the carrier plate has an optimum less wear, whereby the characteristic, i.e., the movement gap between the carrier plate and the rocker plate, hardly changes during the use of the cleaning device. In order to prevent the carrier from undesirably separating from the rocker, the carrier and the rocker preferably additionally have fastening means, such as snap means. Its fixing means can be integrated into the arrangement means. The fixing means prevents the carrier from being displaced perpendicular to the plane of the rocker.

The invention proposes that the two arrangement means have a distance of more than 100 mm and a distance of up to 400 mm. The two arrangement means have a distance of more than 150 mm. In principle, the arrangement means is preferably as far as possible from each other, if the geometrical dimensions of the carrier and the rocker are allowed. When the carrier is engaged, the arrangement of the carrier plates is snapped into the arrangement of the rocking plates without a gap, and vice versa, so that it can only rotate about the central axis of the pair of arrangement means. In order to prevent its rotational movement based on this, the arrangement of the carrier plate as far as possible from its center of rotation engages the corresponding arrangement of the rocker plate such that all motion plans parallel to the rocking plane are blocked. In the case of a carrier or rocker having a length of, for example, 300 mm, the distance between the pairs of the arrangement means is in particular greater than 200 mm, particularly preferably greater than 250 mm.

Furthermore, the invention proposes that the first arrangement means without gaps has a positional tolerance of less than 1 mm. The positional tolerance of the first arrangement means that the positional tolerance is preferably approximately zero. This can be achieved, for example, by means of a means for positively inserting the arrangement of the carrier plates into the rocking plate, or by means of a means for positively inserting the arrangement of the rocking plates into the carrier. Wherein, the outer diameter of the means for arranging the carrier, for example, should be substantially the same as the inner diameter of the means for arranging the rocker. In the case where the positional tolerance is at most 1 mm, the first arrangement means a motion gap of 1 mm, which is still a concept of "no gap" within the scope of the present invention. The motion gap allows motions of up to 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, or smaller scale movements.

Furthermore, the invention proposes that the second arrangement means has a movement gap of 5 mm up to 30 mm. The second arrangement means a dual motion gap for the particularly simple engagement of the carrier and the rocker. The given motion gap extends only in a single direction of motion. The second arrangement means that all other directions of motion of the pair are blocked.

The invention proposes that the first arrangement means with no play has a centering receptacle and a centering element that can be snap-fit into the centering receptacle. Furthermore, the invention proposes that the second arrangement means has a tolerance compensation receptacle and a tolerance compensation element that can be snapped into the tolerance compensation receptacle. The centering receptacle of the first arrangement means, for example, can be a recess in the material of the carrier or the rocker, the centering element snapping into the recess in a form-fitting manner. The centering element can be, for example, a projection, a dome, a projection or the like, which can be inserted into the centering receptacle such that the outer contour of the centering element conforms to the inner contour of the centering receptacle. In the case of a direction perpendicular to the direction of movement of the movement gap, the second arrangement means the pair of tolerance compensation elements can be configured to match the shape of the tolerance compensation receptacle, for example by means of a corresponding division of the outer contour of the tolerance compensation element It corresponds to the inner contour of the tolerance compensation housing. In the case of the direction of the movement gap, there is no shape matching, so that in the case where the direction of movement is not blocked by the first arrangement means without gaps, the tolerance compensation element can in principle be within the tolerance compensation receptacle motion. The second arrangement means the dual tolerance compensation element can also be constructed in the manner of a dome, a bump, a projection or the like, and accordingly snaps into the tolerance compensation receptacle. Furthermore, it is irrelevant whether the tolerance compensation receptacle, the tolerance compensating element, the centering receptacle and/or the centering element are arranged or constructed on the rocker or carrier, within the scope of the invention. The only important point is that the corresponding arrangement means that the first arrangement means is arranged on the carrier, and the corresponding second arrangement means is arranged on the rocker.

The invention proposes that the inner dimension of the tolerance compensating portion provides a spatial direction of its kinematic gap, the length of which is at least 1.5 times up to 5 times the dimension of the tolerance compensating element along its spatial direction. Thereby, the tolerance compensation accommodating portion is disposed such that the movement gaps of the second arrangement means dual arrangement means are opposed to each other. In the case where the tolerance compensating element has a length of, for example, 10 mm with respect to the direction of its movement gap, the length of the tolerance compensating accommodating portion is preferably at least 15 mm up to 50 mm.

In particular, the invention provides that the centering element and/or the tolerance compensation element have a convex outer contour. Through the curved geometry, the tolerance compensating element and the tolerance compensation accommodating portion, or the centering element and the centering accommodating portion can roll over the abutting surfaces of each other in the case where the rocking plate is oscillated in a circular shape, thereby Further reduce the wear that may occur. Therefore, unlike the motion of friction using other cross-sectional shapes, the curved shape has an advantage.

Furthermore, the invention proposes that the second arrangement means has two guiding means which are substantially parallel to one another and are arranged in a form-fitting manner between the guiding means. The forked region of the rocker plate can be, for example, a corresponding abutment rib of the buckle carrier. Thereby, the second arrangement means the direction of motion of the dual is preset. The second arrangement means, in particular, can also have a guide slide comprising a guide rail or the like.

In addition, the present invention proposes that the longitudinal extension of the tolerance compensation accommodating portion provides a connection line connecting the centering accommodating portion and the tolerance compensation accommodating portion substantially larger than the spatial direction of the motion gap. 0° up to 80° angle, especially 15° to 30°. Therefore, the longitudinal extent of the tolerance compensating portion is preferably not parallel to the direct connection of the center of the tolerance compensating element and the centering element in terms of the state in which the carrier plate is coupled to the rocker plate. The longitudinal extent of the tolerance compensation receptacle can be at an angle of up to +/- 80° with respect to its connecting line. When the user engages the carrier plate on the rocker plate, the direction of tolerance to compensate for the longitudinal extent of the receiving portion is significant. Depending on which direction the user typically fixes the carrier to the rocker, it may be advantageous to use larger or smaller angles. In practice, an angle of 15 to 30 is advantageously employed. Furthermore, the longitudinal extent of the tolerance compensation receptacle is advantageously perpendicular to the rotational trajectory, while the tolerance compensating element forms the rotational trajectory if the carrier or rocker is free to rotate independently about the first arrangement.

In addition to the aforementioned cleaning device, the present invention also proposes a wet cleaning device having such a cleaning device. This wet cleaning device can in principle be any cleaning device that can only or mainly perform wet cleaning. These include hand-held wet cleaning equipment, but also self-propelled wet cleaning equipment, especially cleaning robots. In addition, combined dry and wet cleaning equipment is also included. Further, in addition to the conventional floor cleaning apparatus for cleaning the floor, for example, a wet cleaning apparatus for cleaning the upper area of the floor, such as for cleaning window glass, shelves, skirting boards, steps, and the like, is also included.

Moreover, all of the features described with respect to such cleaning devices are similarly applicable to the wet cleaning apparatus of the present invention.

Figure 5 is a longitudinal cross-sectional view of the rocker plate along with the carrier plate connected thereto.

The invention is explained in detail below in conjunction with the examples. Figure 1 shows a wet cleaning device 2, here constructed as a hand-held wet cleaning device 2, which is provided with a basic device 21 and a cleaning device 1 constructed as an attachment. The cleaning device 1 is held in the detachable manner on the basic device 21. Furthermore, the basic device 21 has a handle 22, here for example a retractable design, so that the user of the wet cleaning device 2 adjusts the length of the handle 22 according to its height. Furthermore, a handle 23 is arranged on the handle 22, which the user can hold during a conventional wiping operation to guide the wet cleaning device 2, i.e. to move it over the surface to be cleaned. During the wiping operation, the user typically guides the wet cleaning device 2 on the surface to be cleaned in the opposite direction of motion. During this process, the user alternately pushes and pulls the wet cleaning device 2 on. Disposed on the handle 23 is a switch 24 which can be used, for example, to switch the motor of the wet cleaning device 2 on and off.

The cleaning device 1 has a combination of a rocker 3, a carrier 4 and a cleaning element 5 as shown in FIG. The rocking plate 3 has a rotating shaft accommodating portion 20 for a drive shaft of the motor at the center of the top side thereof. The drive shaft is used in combination with the eccentric to both secure the rocker 3 to the cleaning device 1 and to cause an oscillating rocking motion of the rocker 3. Furthermore, the content relating to the eccentric drive of the rocker 3 can be found in the publication EP 2 578 131 A1.

Preferably, the rocker 3 is driven at an oscillation frequency of, for example, 1000 rpm to 2000 rpm. During the wiping operation, the rocking movement of the rocker 3 relative to the housing of the cleaning device 1 is superimposed on the displacement of the wet cleaning device 2 by the user on the surface to be cleaned. The two movements, i.e. the manual displacement movement, are carried out in the same plane as the rocking plane of the rocker 3, together with the rocking motion of the rocker 3.

The cleaning element 5 is a cleaning cloth having a partial elasticity, in particular a microfiber cloth. The cleaning element can be secured to the corresponding cleaning element holder (not shown) of the carrier 4 by means of a cleaning element holder 25, here a devil felt.

In order to align the carrier 4 with respect to the rocker 3, the carrier 4 and the rocker 3 have corresponding arrangement means 6-12, wherein the arrangement means 6, 7, 8, 9 of the carrier 4 and the rocker can be respectively arranged The arrangement means 10, 11, 12 of 3 are connected to the arrangement means pair 13, 14. The arrangement means 6 , 7 , 8 , 9 of the carrier 4 here comprise two dome-shaped centering elements 16 and four tolerance compensation elements 18 . The arrangement means 10, 11, 12 of the rocker 3 include the centering receiving portion 15 and the tolerance compensation receiving portions 17, 26 shown in detail in FIG.

Figure 3 shows the carrier 4 of Figure 2. The carrier 4 first has two arrangement means 6, 7 which are formed on the edge regions of the carrier 4 which are arranged diagonally opposite each other. Specifically, the arranging means 6, 7 are dome-shaped centering elements 16 which are directed in the direction of the rocker 3 in a state in which the carrier 4 is placed on the rocker 3. In the connected state, the centering elements 16 are constructed on the carrier 4 in a point-symmetrical manner with respect to the rotating shaft accommodating portion 20 of the rocking plate 3. Furthermore, the carrier plate 4 has arrangement means 8, 9 which are constructed as tolerance compensation elements 18. The tolerance compensating element 18 provides a guiding means parallel to the longitudinal extent of the carrier plate 4.

FIG. 4 shows a bottom perspective view of the rocker 3 constructed corresponding to the carrier 4 . The side shown on the rocker 3 is the side facing the carrier 4 in the state in which the carrier 4 and the rocker 3 are connected. Corresponding to the two centering elements 16 of the carrier plate 4, the rocker plates 3 each have an arrangement means 10, 12, here a centering receiving portion 15, which can introduce one of the centering elements 16 into the centering volume The portion is configured to implement a gapless connection and has a tolerance compensation receptacle 26 for the centering elements 16 disposed diagonally opposite each other. The centering receptacle 15 and the corresponding centering element 16 housed therein form the arrangement means pair 13 in the connected state. The inner contour of the substantially cylindrical centering accommodating portion 15 corresponds to the outer contour of the centering element 16, so that the carrier plate 4 is prevented in the case where the arrangement means 6, 10 of the arrangement means pair 13 are connected. A translational movement occurs between the rocker 3 and the rocker 3. The carrier plate 4 is rotatable relative to the rocker plate 3 only around the center of the arrangement means pair 13. However, this point is avoided by engaging the second arrangement means pair 14, the arrangement means pairing the arrangement means 11 of the rocker 3 constructed as the tolerance compensation receptacle 17 and the corresponding arrangement means constructed as the tolerance compensating element 18. 8, 9 constitutes. The tolerance compensation receptacle 17 of the rocker 3 is formed as an abutment member which can be abutted against the tolerance compensating element 18 of the carrier 4 . The tolerance compensation accommodating portion 17 of the rocking plate 3 in the form of a fork is fastened to the tolerance compensating element 18 of the carrier plate 4. Thereby, a rotational movement of the pair 13 around the first arrangement means is also prevented. Another arrangement means the dual 14 is formed by the tolerance compensation receptacle 26 and the centering element 16 housed therein.

Fig. 5 shows a longitudinal sectional view of the rocker plate 3 connected to the carrier plate 4. The longitudinal section shown is a plane in which the cutting arrangement means the faces 13, 14 which are parallel to the rocking plane of the rocker 3. The first arrangement means the pair 13 has a dome-shaped centering element 16 which is received in the centering receptacle 15 . The second arrangement means the pair 14 has a tolerance compensation receptacle 26 which is constructed in accordance with the pattern of the grooves. The corresponding centering element 16 of the carrier 4 is snapped into the tolerance compensation receptacle 26 of the rocker 3. Of course, the arrangement means 7, 10 of the first arrangement means pair 13, and the arrangement means 7, 12 of the second arrangement means 12 can be selectively constructed on the rocker 3 if not selectively constructed on the carrier 4. The two arrangement means have a distance a to the center of symmetry of the pairs 13, 14, which is here for example 220 mm. The second arrangement means that the tolerance compensation receptacle 26 of the pair 14 has a length of 20 mm with respect to the longitudinal extent 27 in order to provide a movement gap for the centering element 16 housed therein during engagement. The centering element 16 has a diameter of, for example, 11 mm. The first arrangement means that the centering element 16 of the pair 13 also has an outer diameter of 11 mm, and the inner diameter of the corresponding centering receiving portion 15 has an inner diameter of 11 mm, so that the first arrangement means pair 13 can be regarded as substantially No gaps. The second arrangement means that the longitudinal extent 27 of the tolerance compensation receptacle 26 of the pair 14 forms an angle a which is not equal to zero degrees with the connecting line 19 of the two arrangement means pairs 13, 14. The angle α here is, for example, about 15°.

The carrier 4 is arranged on the rocker 3 in such a way that the user of the cleaning device 1 tilts the cleaning device 1 relative to the surface to be cleaned such that the rocker 3 is separated from the surface to be cleaned or at least has an inclination with respect to the surface. In this way, the carrier plate 4 to be fixed can be placed on the surface to be cleaned, advantageously in such a way that the longitudinal extent of the carrier plate 4 is parallel to the longitudinal extent of the rocker plate 3. Subsequently, the user guides the cleaning device 1 or the rocker 3 on the carrier 4 such that the arrangement means 6, 7, 8, 9 of the carrier 4 are snapped into the corresponding arrangement means 10, 11, 12 of the rocker 3. In order for the user to simplify the engagement, the carrier 4 is applied in a symmetrical shape such that it is possible to use two possible mounting positions that differ by 180°. When the carrier 4 is joined, the centering element 16 of the carrier 4 is snapped into the centering receptacle 15 of the rocker 3. Therefore, the carrier 4 cannot perform a translational movement in a plane parallel to the rocking plane. Only a rotational movement around the central axis of the centering element 16 can be achieved. To prevent this, the centering element 16 of the carrier 4, which is spaced apart by a distance, is snapped into the tolerance compensation receptacle 26 of the rocker 3. Further, the tolerance compensating element 18 of the carrier plate 4 and the tolerance compensation accommodating portion 17 of the rocking plate 3 are engaged with each other. Therefore, all motion schemes in the sway plane are blocked. Although not shown in the drawings, the carrier plate 4 and the rocking plate 3 additionally have a snapping means for fixing, thereby preventing separation perpendicular to the rocking plane, that is, the carrier plate 4 is separated from the rocking plate 3.

Subsequently, the rocking plate 3 is rotated by a motor drive in a usual manner, wherein the drive shaft that is snapped into the rotary shaft housing 20 surrounds the central axis of the cleaning device 1 for eccentric movement. Therein, the duals 13, 14 are carried by the two arrangement means to carry the carrier 4 such that the carrier and the rocker 3 perform the same movement, i.e., rotate in the rocking plane.

Of course, the fixing elements 6-12 of the carrier plate 4 and the rocking plate 3 can be arranged in the case of the arrangement means pair 13, 13 of the arrangement means such that the carrier plate 4 is arranged on the rocker plate 3 without play. On different boards. In practice, the arranging means 6-12 are preferably supplemented by corresponding snap means, the snap means preventing the carrier 4 from separating itself from the rocker 3. For example, the arrangement means duals 13, 14 can be separated only after the buckles are separated, in particular by, for example, button manipulation. However, this point is not the subject of the present invention.
