The joint arrangement of the known wet cleaning device is designed such that the hand guide part is pivotable starting from a vertical circumferentially in all directions relative to the bottom part. In this case, the joint arrangement allows a torque transmission between the hand guide part and the bottom part for the purpose of manual control of the bottom part on the bottom surface. Next, the known wet cleaning device has a arranged on the bottom part and rotatable by means of a drive tillage tool. The tillage tool is in the operating state on the bottom surface and causes a permanent linear propulsion along a cleaning direction. In addition, a arranged behind the tillage tool Saugleistenanordnung is provided. This serves to suck liquid from the bottom surface.

The object of the invention is to provide a wet cleaning device of the type mentioned, which allows an improved cleaning of floor surfaces.

This object is achieved in that a collecting device is provided in the cleaning direction between the at least one tillage tool and the Saugleistenanordnung arranged by the tillage tool to the rear traps transported solid particles and collects. By the solution according to the invention an improved cleaning of the bottom surface is made possible. In particular, according to the invention, it is avoided that solid particles transported in the direction of the suction strip arrangement by means of the tilling tool are deposited before and / or under the suction strip arrangement. Solid particles accumulated in such a manner may affect the suction of the squeegee assembly. This may cause the liquid used in wet cleaning to be unsatisfactorily sucked from the bottom surface. This may in particular lead to streaking on the floor surface to be cleaned, a laxity of the Saugleistenanordnung and ultimately to a poor cleaning. The solution according to the invention counteracts this by providing the collecting device and being arranged in the cleaning direction between the soil cultivation tool and the suction strip arrangement. The collecting device serves to collect and collect the solid particles. For this purpose, the collecting device may preferably have a collecting container, in which the solid particles are collected and collected.

By means of the feed element, the solid particles can be selectively fed to the collecting container. For this purpose, the supply element can be formed rampen, line, channel, funnel-shaped or the like. In this case, the supply element can be integrally formed on the collecting container or assembled as a separately manufactured component with the collecting container. This embodiment of the invention allows a further improved cleaning effect.

In a further embodiment of the invention, the supply element has a plate-shaped extension of the collecting container. Preferably, the extension is substantially parallel to the bottom surface and insofar extends horizontally. In this case, the plate-shaped extension can be arranged at least in sections in the vertical direction between the bottom surface and the soil working tool. The extension serves for improved transport of the solid particles in the direction of the collecting container and thus forms, in simplified terms, an extension of the supply element.

In a further embodiment of the invention, the collecting device has a support element which supports the collecting container in the operating state on the bottom surface. In this case, the support element preferably serves a sliding or rolling support of the collecting container and may be designed in the form of a slider, a wheel, a roller or the like.

In a further embodiment of the invention, the collecting device has at least one discharge element, which dissipates liquid collected in the collecting container. It is Not readily preventable that the rotary tillage tool in addition to the solid particles throws liquid from the bottom surface, which can get into the receptacle in this way. For the derivation of this liquid, the discharge element is provided. By means of the discharge element it is avoided that the collecting container overflows in the course of the wet cleaning process and thereby solid particles are flushed out of the collecting container. Preferably, the discharge element forms a fluid-conducting passage from an inner side of the collecting container to an outer side of the collecting container. The passage is dimensionally matched to the solid particles to be collected in the collecting container, so that they can not be flushed out of the collecting container through the passage.

A wet cleaning device 1 according to Fig. 1 is designed in the form of a scouring-suction machine and provided for wet cleaning of a floor surface B. The floor surface B is presently a hard floor in a building interior, not shown. The wet cleaning device 1 has a hand guide part 2 and a bottom part 3. The hand guide part 2 is connected by means of a hinge assembly 4, which comprises two unspecified joint axes, relatively pivotally connected to the bottom part 3 pivotally. The joint assembly 4 is arranged at the front end side of the hand guide part 2 and designed such that the hand guide part 2, starting from a vertical circumferentially in all directions in angular positions relative to the bottom part is pivotable, wherein the hand guide part 2 in each of these angular positions to transmit torque to the bottom part 3 in an operative connection stands. This type of articulation between hand guide part 2 and bottom part 3 is from the EP 2 832 277 B1 is known, to the relevant disclosure to explain the structure and / or operation of the hinge assembly 4 hereby expressly referred to and incorporated by reference. The hand guide part 2 is elongated and protrudes in the basis Fig. 1 apparent configuration slightly inclined upward from the bottom part 3 from. The hand guide part 2 has a central, dimensionally stable support tube 5, on the upper end face region of which two handles 6 projecting to opposite sides are arranged for manual guidance of the wet cleaning device 1. Next, the hand guide part 2 has a front mounted on the support tube 5 septic tank 7 and a rear side attached to the support tube 5 fresh water tank 8. At a lower end region of the support tube 5, a suction drive 9 is arranged, which serves in a manner described in more detail below for the suction of liquid from the bottom surface B.

The bottom part 3 is based in the Fig. 1 apparent operating state on the bottom surface B and has a soil working tool 10 and a Saugleistenanordnung 11. In the present case, the soil working tool 10 has two plate tools which are each designed in the form of a disc brush 13. These are rotatable in opposite directions by means of a respective drive 12 and, in the operating state, contact the bottom surface B at least in sections. Instead of two drives 12, only one drive common to the plate brushes 13 can be provided. The disc brushes 13 are each mounted in a generally known manner rotatably in a housing 14 of the bottom part 3, wherein a respective axis of rotation of the disc brushes 13 is oriented substantially vertically to the bottom surface B. In the operating state the rotates - in relation to the plane of the Fig. 2 left disc brush 13 counterclockwise; the right plate brush 13 rotates in the clockwise direction. Here, the tillage tool 10 is designed such that in the operating state, a permanent linear propulsion along a cleaning direction R is effected on the bottom part 3. For this purpose, the unspecified axes of rotation of the disc brushes 13 in the present case slightly tilted from the vertical against each other. This causes in operation of the tillage tool 10 to a respective circumference of the disc brushes 13 different frictional distribution of the disc brushes 13 on the bottom surface B. Consequently, the opposite rotation causes the disc brushes 13 not only a processing of the bottom surface B, but in addition the said permanent linear propulsion along the Cleaning direction R. Such a design of the tillage tool is already in the EP 2 832 277 B1 described. Their disclosure in this regard is hereby expressly referred to for additional explanation of the propulsion function of the tillage tool 10 and reference is made.

The Saugleistenanordnung 11 is - with respect to the cleaning direction R - arranged behind the tillage tool 10 and provided for sucking liquid from the bottom surface B. The Saugleistenanordnung 11 has two to form a defined intake slot 15 spaced apart sealing lips 16. The intake slot 16 is operatively connected in a basically known manner by means of an intake manifold 17 via a suction line 18 with the recovery tank 7. In this way, by means of the suction drive 9, which is operatively connected to the suction line 18, liquid sucked between the sealing lips 16 and transported into the recovery tank 7.

For wet cleaning of the bottom surface B, in the present case water is applied to the bottom surface B, starting from the fresh water tank 8 in the region of the tilling tool 10. The applied water can dissolve dirt located on the bottom surface B and the scouring process of the mutually rotating plate brushes 13 support. The resulting wastewater is sucked by means of the Saugleistenanordnung 11 and transported in the manner described above in the recovery tank 7. In the above-described wet cleaning, it can not be readily avoided that on the bottom surface B located solid particles, such as dust, hair or smaller objects, are deposited in the region of Saugleistenanordnung 11. This can lead to an impairment of the suction power and a lubricity of the sealing lips 16. As a result, ultimately an unsatisfactory cleaning result can be achieved.

To counteract this, the wet cleaning device 1 has a collecting device 19 arranged in the cleaning direction R between the at least one soil working tool 10 and the suction strip arrangement 11. The collecting device 19 is designed in such a way that solid particles transported by the tilling tool 10 - in relation to the cleaning direction R - are collected and collected. Details of the collecting device 19 are in particular on the basis of FIGS. 2 and 3 seen. Thus, the collecting device 19 to a collecting container 20, which is provided for collecting and collecting the not more apparent solid particles. In the present case, the collecting container 20 extends essentially over the entire width of the soil cultivation tool 10 and is fixed to the suction strip arrangement 11 by means of two fastening elements 21. The fastening elements 21 are designed such that the collecting container 20 for emptying and cleaning in a simple manner by the Saugleistenanordnung 11 is solvable. A rear wall region of the collecting container 20 in the cleaning direction R is in the present case in the form of a curved contour of the suction strip arrangement 11. As a result, available space can be exploited in an improved manner. In a front region facing the soil working tool 10, the collecting container 20 has a supply element 22. The supply element 22 is in the cleaning direction between a collecting opening 23 (FIG. Fig. 3 ) of the collecting container 20 and the tillage tool 10. The supply element 22 is used to supply the solid particles through the collecting opening 23 into the interior of the collecting container 20. The supply element is presently designed in the form of a ramp 22 and integrally formed on the collecting container 20, which is preferably made of plastic. The ramp 22 is - in the operating state according to Fig. 1 - At an acute angle to the bottom surface B employed. In addition, the collecting device 19 has a discharge element 24. The discharge element 24 serves for the discharge of liquid collected in the collecting container 19. This is because it can not be readily avoided in the above-described wet cleaning that centrifuged by the rotating plate brushes 13 liquid from the bottom surface B and transported into the interior of the collecting container 19. In the embodiment according to the Fig. 1 to 3 has the derivative element 24 a liquid-permeable drain wall section 25 of the collecting container 19. As based on Fig. 2 is schematically illustrated, the drain wall portion 25 is perforated in this case sieve-like, so that said liquid is discharged from the interior of the collecting container 20 in the direction of the bottom surface B down and sucked in the further course of the cleaning operation of the Saugleistenanordnung 11. In addition, the collecting device 19 has a retaining element 26. The retaining element 26 serves to reliably retain solid particles collected in the collecting container 20 during the cleaning process. The retaining element 26 in the present case has a retaining wall section 27 of the collecting container 20, which is arranged adjacent to the collecting opening 23. The retaining wall section is designed in the form of an undercut ramp 27, which extends in the operating state relative to the bottom surface B at an acute angle.

Further embodiments of inventive wet cleaning devices 1a, 1b, 1c are based on the Fig. 4, 5 as well as 9 and 10 can be seen. The embodiments of wet cleaning devices 1, 1a according to the invention have a substantially identical construction with regard to their structural as well as functional features. Components and portions that are identical in the wet cleaning devices 1 to 1 c are provided with identical reference numerals. To avoid repetition, such identical components and sections are not explained separately in each embodiment, but instead reference is made to the relevant disclosure in connection with the wet cleaning device 1. Functionally identical components and sections, which are different in their structural design, are denoted by the same reference numerals with the addition of lowercase letters.

The wet cleaning device 1a according to 4 and 5 differs only by a different design of the local catcher 19a of the wet cleaning device 1. Consequently, only the essential differences between the collecting device 19 and the collecting device 19a will be discussed in more detail. The collecting device 19a has a feed element 22a, which is provided with a plate-shaped extended extension 28. The extension 28 is integrally formed on the collecting container 20a and extends substantially horizontally. Based Fig. 4 It can be seen that the extension 28 extends in the cleaning direction R to below the soil working tool 10, so that the disc brushes 13 rest on their extensions in the direction of the catcher 19a facing peripheral portions in sections on the extension 28. In this case, the extension 28 causes an improved supply of solid particles in the collecting container 20a. Further, in contrast to the collecting device 19, the collecting device 19a has a discharge element 24a, which has a plurality of arranged on the collecting container Drain openings 29 has. In addition, a damping element 30 is provided which is arranged on a back in the cleaning direction R, inner wall portion 31 of the collecting container 20a. The damping element 30 is designed so resilient that by means of the counter-rotating disc brushes 13 in the collecting container 20 a thrown solid particles are slowed down, so that a rebound from the wall portion 31 and from the collecting container 20 a out is avoided. Incidentally, the collecting device 19a provides a different type of attachment to the Saugleistenanordnung 11. For this purpose, fastening elements 21a are provided. The fastening elements 21a are each designed tab-shaped and provided for releasable connection with unspecified, fixed to the Saugleistenanordnung 11 bolt.

Further embodiments of inventively designed collecting devices 19b, 19c and 19d are based on Fig. 6, 7 or 8 can be seen. In the following, in order to avoid repetition, again only the essential differences of the collecting devices 19b to 19d will be discussed.

The collecting device 19b after Fig. 6 has a stripping element 32 arranged on the lower side of the collecting container 20b. In the present case, the stripping element 32 has a sealing lip 33 and a textile fabric in the form of a stripping fleece 34. The sealing lip 33 is arranged in the cleaning direction R at the front end and below the supply element 22b. The stripping fleece 34 is arranged in the cleaning direction R behind the sealing lip 33 and in front of the discharge element 24b. In the basis of Fig. 6 apparent operating state, both the sealing lip 33 and the Abstreifvlies 34 are on the bottom surface B. The stripping element 32 serves to achieve an improved seal between an unspecified underside of the collecting container 20b and the bottom surface B. This avoids that solid particles can be transported under the collecting container 20 b and thus attached to the Saugleistenanordnung 11.

In contrast to the above-described embodiments, the embodiment according to Fig. 7 at least one guide element 35. The collecting device 19c, more precisely: the collecting container 20c, is mounted floating by means of the guide element 35 in the vertical direction H relative to the suction strip arrangement 11 and / or the soil working tool 10. As a result, an advantageous tracking of the collecting container 20c along the bottom surface B can be achieved even with any unevenness of the bottom surface B. For this purpose, the guide element in the present case has a stud bolt 37 engaging in a slot 36. In the present case, the slot 36 is formed on the collecting device 19c. In contrast, the stud bolt 37 is assigned here the Saugleistenanordnung 11 and fixed to this. In this case, the slot 36 is formed on a tab 38, which is arranged on a cleaning direction R in the rear, inner wall portion of the collecting container 20c. The tab 38 can be integrally formed on the collecting container 20c or assembled as a separately manufactured component with the collecting container 20c. In the present case, the latter applies. In addition, the catching device 19c has a support element 39. The support element 39 serves for a rolling support of the collecting container 20c on the bottom surface B. For this purpose, the support element is designed in the form of a support wheel 39, which is fixed in rotation about an axis of rotation D to the collecting container 20c. The axis of rotation D is arranged in a cleaning direction R in the rear, the Saugleistenanordnung 11 facing portion of the collecting container 20c. In the basis of Fig. 7 apparent operating state of the collecting container 20c is tilted due to the extent eccentric support forward towards the tillage tool and slidably supported on a bottom portion of the feed element 22c on the bottom surface B.

The basis of the Fig. 8 apparent collecting device 19d designed according to the invention is essentially identical to the collecting device 19a according to FIG Fig. 5 , In contrast to this, however, the collecting device 19d does not provide a plate-shaped extension 28. The damping element 30 is made of a non-descript knitted fiber material.

The common feature of the wet cleaning devices 1 and 1a is that the collecting devices 19, 19a and 19b and 19c there in the cleaning direction R are arranged essentially completely between the soil cultivation tool 10 and the suction strip arrangement 11. In contrast, the wet cleaning apparatus 1b according to FIG Fig. 9 before that the local catcher 19e is only partially arranged between the soil working tool 10 and the Saugleistenanordnung 11. Based Fig. 9 It can be seen that the collecting container 20e of the collecting device 19e is arranged in the cleaning direction R behind the Saugleistenanordnung 11, wherein the supply element 22e starting from the collecting container 20e forward in the direction of the tillage tool 10 across the Saugleistenanordnung 11 across and obliquely downward toward the bottom surface B is extended. This will be the basis Fig. 9 schematically indicated and unspecified solid particles transported along the arrow-shaped trajectory on the Saugleistenanordnung 11 away into the interior of the collecting container 20 e.

Another inventively designed wet cleaning device 1c is based on Fig. 10 seen. In contrast to the above-described wet cleaning devices 1 to 1b, the collecting device 19f has no collecting container. Instead, the collecting device 19f has a receiving element 40, which rests in the operating state at least partially on the bottom surface B and is designed such that from the tillage tool 10 to the rear transported solid particles on and / or in the receiving element can be collected and collected. For this purpose, the receiving element in the present case in the form of a cleaning fleece 40 is formed. The cleaning fleece 40 can in particular be made of fibers and / or formed like a sponge.

It is understood that the multiplicity of the above-described structural and functional features of the collecting devices 19 to 19f can also be embodied in a single collecting device designed according to the invention, as far as their combination is technically meaningful. In particular, the features of the collecting devices 19 to 19c may be provided in their entirety or in corresponding sub-combinations on an inventively designed collecting device.
