Description

 Independent regeneration unit for regenerating cleaning elements  

The present invention relates to a separate regeneration unit for regenerating a cleaning element, wherein the regeneration unit has a housing containing a regeneration chamber for at least partially surrounding the cleaning element, wherein the regeneration chamber (4) Further having a rotatable rotating shaft body (6) comprising a receiving area (8) constructed on the circumferential surface (7) of the rotating shaft body (6) for anti-spinning connection with the cleaning element (2) ).

Furthermore, the invention relates to a cleaning element for a wet cleaning apparatus, i.e. a cleaning cylinder having a drum core and a drum casing.

Furthermore, the invention also relates to a kit consisting of a regeneration unit and a cleaning element.

Regeneration units for regenerating cleaning elements are known in the prior art. Among them, it is necessary to distinguish between a non-independent regenerative device and an independent regenerative unit.

DE 102 29 611 B3, for example, discloses a wet cleaning device having a wiping body rotatably rotatable about a rotational axis, wherein the cleaning liquid is taken out of the storage tank and arranged by a spray nozzle arranged in the direction of the axis of rotation of the wiping body Spray to the surface of the wipe. During the wiping operation, the wipes which are wetted in the manner described above are guided on the surface to be cleaned, wherein the wiping system absorbs dirt from the surface to be cleaned. In order to regenerate the wiper, the wiper is separated from the surface to be cleaned, surrounded by the casing of the wet cleaning device, and sprayed with unused cleaning liquid. The wiper rotates so that the cleaning liquid and dirt are discharged out of the wiper to the inside of the casing and transferred to the collection container of the wet cleaning device.

Furthermore, in addition to wet cleaning equipment with integrated regeneration devices, separate regeneration units are also known. These regenerative units are constructed in accordance with the style of the container containing the cleaning liquid and the cleaning elements of the wet cleaning apparatus can be immersed in the container.

The patent specification EP 19 55 639 B1, for example, discloses a kit consisting of a wiper and a reservoir, wherein the wiper has a rotary drive constructed as a gyroscope drive, the rotary drive pressing the wiper to In the case of a partition on the reservoir, the cleaning elements of the wiper are rotated. During this process, the cleaning elements rotate about the longitudinal axis of the wiper. In order to wet the cleaning element with a cleaning liquid, the cleaning element is immersed in the liquid in the reservoir. Subsequently, the wet cleaning element is centrifuged by means of a rotary drive, wherein the contaminated cleaning liquid is again returned to the remaining liquid volume of the reservoir.

Based on the above prior art, it is an object of the present invention to provide an independent regeneration unit that is capable of regenerating cleaning elements without the involvement of a wet cleaning apparatus or other additional auxiliary construction.

In order to achieve the above object, the present invention proposes a separate regeneration unit in which a clean liquid distribution device (11) disposed between the regeneration chamber (4) and the clean liquid chamber (9) in the fluid connection portion (10) is provided.

Preferably, the cleaning element is inserted onto the rotating shaft body in such a manner that the cleaning element is sleeved onto the rotating shaft body with a preferably cylindrical gap such that the cleaning element is arranged coaxially with the rotating shaft body. When the rotating shaft body rotates, the cleaning elements are correspondingly rotated with one another, wherein the liquid and dirt distributed in the cleaning elements and distributed on the cleaning elements are centrifuged and, for example, hit the wall of the regeneration chamber. The peripheral surface of the rotating shaft body has an accommodating area, and the cleaning element is rotatably held on the accommodating area so that the rotation of the rotating shaft body does not cause relative rotation of the cleaning element relative to the rotating shaft body. To achieve this, the circumferential surface thereof may have fastening elements that prevent relative rotation of the cleaning elements relative to the rotating shaft body. The fastening elements can be, for example, projections that snap into the cleaning element, in particular grooves and/or knobs, or snap members and the like. Furthermore, in order to limit the axial clamping of the cleaning element to the rotary shaft body, the circumferential surface of the rotary shaft body can, for example, also have an end stop for the end region of the cleaning element. The separate regeneration unit operates with the aid of a wet cleaning apparatus to regenerate the cleaning elements only by the regeneration unit. In particular, in particular, several cleaning elements can be regenerated in sequence, without the need to connect the cleaning elements to the wet cleaning device for this purpose.

In order to be advantageously connected to the regeneration unit, in particular the rotating shaft body, the cleaning element is preferably cylindrical and has a central recess which can be used to push the cleaning element above the rotating shaft body. The user, for example, manually places the cleaning element onto the rotating shaft body, preferably in a direct self-wetting cleaning apparatus to the regeneration unit. In particular, the wet cleaning device can be placed against the regeneration unit, thereby transferring the cleaning element directly from the axis of rotation of the wet cleaning device to the rotating shaft of the regeneration unit. For this purpose, in particular a spring mechanism or a motor-driven transfer mechanism can be provided.

Furthermore, the invention proposes that the regeneration unit has a dirt collection chamber and/or a clean liquid chamber which is independent of the regeneration chamber and has a fluid connection to the regeneration chamber. Therefore, the dirt collection chamber and/or the clean liquid chamber are constructed separately from the regeneration chamber such that the clean liquid and/or the dirty liquid are not stored in the regeneration chamber, and the cleaning element to be regenerated is not immersed in the clean liquid and / or dirty liquid. The regeneration chamber does not have any volume of liquid that may be stored in contact with the cleaning elements or with the contaminants on the cleaning elements, except as the remaining liquid present therein. Therefore, unlike the prior art, the stored liquid, particularly the clean liquid, is not contaminated, otherwise the stored liquid is greatly contaminated. Rather, only a portion of the liquid currently required for the regeneration of the cleaning elements and/or still present in the cleaning elements or on the cleaning elements is always provided in the regeneration chamber. The clean liquid is stored separately in the clean liquid chamber, so that for the regeneration of the cleaning element, a new volume fraction of clean liquid is always moved into the regeneration chamber. This effectively prevents the surface to be cleaned from being back-contaminated. In addition, the collection chamber is constructed independently of the regeneration chamber and the clean liquid chamber, so that the sewage is treated separately, in particular through the domestic sewage connection. It is also advantageous to connect the clean liquid chamber to the household clean liquid joint to replenish the clean liquid into the clean liquid chamber at any time. In addition, the dirt collection chamber and the clean liquid chamber may also be connected through a flow channel and a processing device, wherein the treatment device filters out the dirt in the dirt collection chamber and only moves the purified liquid into the clean liquid chamber. The fluid connection between the clean liquid chamber and the regeneration chamber preferably corresponds to a liquid pump that can feed clean liquid from the clean liquid chamber into the regeneration chamber. Alternatively, the clean liquid chamber may be arranged above the regeneration chamber in terms of the conventional orientation of the regeneration unit during the regeneration operation, such that the clean liquid may preferably be disposed in the fluid connection based on the hydrostatic pressure. The valve enters the regeneration chamber with the participation of the valve that closes and opens the fluid connection. The sump and/or regeneration chamber can also correspond to a liquid pump that draws and/or pumps the effluent from the regeneration chamber. Alternatively, the sump chamber may preferably be disposed below the regeneration chamber (in terms of the conventional orientation of the regeneration unit during the regeneration operation) such that the effluent flows from the regeneration chamber into the sump chamber due to gravity, and may Starting at this point, the regeneration unit is advantageously output with the aid of a liquid pump. In particular, a liquid pump that discharges the dirty liquid from the collection chamber or the regeneration unit for external treatment may be provided.

According to one embodiment, the clean liquid chamber and/or the dirt collection chamber and/or the regeneration chamber can be removed from the regeneration unit. This makes it especially easy to clean them. In addition, the user can thereby fill the clean liquid chamber with clean liquid outside the cleaning unit, i.e., on the wash basin. Thus, for example, the dirt collection chamber can also be emptied on the wash basin.

Preferably, the clean liquid dispensing device is constructed in conjunction with the liquid pump such that the wetting of the cleaning elements in the regeneration chamber is tailored to the type and/or strength of the contamination. In particular, the regeneration unit can have detection means for identifying the degree of contamination of the cleaning elements. In particular, the degree of contamination can be determined based on the contamination of the dirty liquid flowing from the regeneration chamber into the collection chamber. Preferably, the clean liquid dispensing device or liquid pump is coupled to the control unit of the regeneration unit to control the amount of clean liquid that is moved into the regeneration chamber.

The clean liquid dispensing device preferably has a guiding system that is introduced into the regeneration chamber in different regions.

In view of the above, the present invention provides that the clean liquid dispensing device has a plurality of discharge openings, the discharge directions of which are aligned with different circumferential zones of the rotating shaft body. This design enables the cleaning element to be optimally and uniformly wetted on its circumference. The discharge openings of the clean liquid dispensing device are, for example, arranged one above the other in terms of the longitudinal extent of the rotating shaft body such that the cleaning elements that are sheathed onto the rotating shaft body are completely wetted by the liquid by being rotated in the circumferential direction. Due to the gravity acting on the clean liquid, the clean liquid flows out in the direction of the longitudinal extent of the cleaning element, so that the entire circumference of the cleaning element is wetted by the clean liquid, thereby regenerating the cleaning element. More preferably, each of the discharge openings corresponds to a nozzle that expands the jet of liquid discharged from the discharge opening, thereby not only spraying the circumferential plane of the cleaning element, but also the direction of the longitudinal extension of the cleaning element. Define sections for spraying. The type, shape and/or size of the nozzle or discharge opening can be selected in conjunction with the output pressure of the liquid pump to vary, for example, the penetration depth of the material into which the clean liquid penetrates the cleaning element. For example, the flow rate can be varied, in particular, by the size of the discharge opening, the flow rate of which affects the penetration depth of the material from which the liquid jet penetrates the cleaning element, thereby affecting the cleaning effect.

The clean liquid chamber and/or the clean liquid dispensing device may in particular correspond to a heating device for heating the liquid therein. The heating device can, for example, be arranged in or on the wall of the clean liquid chamber and/or the clean liquid dispensing device. The heating device is preferably adapted to heat the liquid to above 60 ° C to remove, for example, bacterial contamination of the cleaning elements during the regeneration process. The heating device can for example be a resistance heating element.

Furthermore, the regeneration unit can have an electric motor with a drive connection towards the rotating shaft body. The rotating shaft body of this regenerative unit is thus driven by a motor, wherein a transmission can also be arranged between them to change the rotational speed of the rotating shaft body. Alternatively, the rotating shaft body can be manually rotated, for example, via a crank that can be manipulated by a user of the regeneration unit.

This regeneration unit can have a battery for powering the electric motor and/or the liquid pump and/or the heating device. In this way, the regeneration unit can be installed in the environment in a completely unrelated manner to the household power source. The battery can supply power to a plurality of different power devices and electronic devices of the regeneration unit. Preferably, the battery is mainly an electric motor for rotating the rotating shaft body, a liquid pump for the clean liquid distribution device, and a clean liquid for the regeneration process. Heating by heating device or other device. Furthermore, the regeneration unit can also have a cable for connecting a household power source, which can be used, for example, to recharge the battery. In addition, the regenerative unit can be coupled to the base or have a detachable base that has a cable that is coupled to a charge control device for the battery. The regeneration unit is independent of the location of the outlet in the case of battery operation, so that the regeneration unit can be used particularly flexibly, for example, in houses, in cars, in gardens.

Furthermore, the regeneration unit may have a scraping device arranged in the regeneration chamber, constructed along the longitudinal extent of the rotating shaft body, and having at least one active element that is directed radially toward the rotating shaft body. The active element is adapted to mechanically clean the cleaning element during the passage of the cleaning element from the side of the active element as the rotating shaft body rotates, thereby mechanically treating the fibers or surface material of the cleaning element and discharging dirt or dirt. The scraping device is disposed within the regeneration chamber such that the active member contacts the cleaning member, preferably the material that snaps into the cleaning member. Therefore, the cleaning element is regenerated not only by centrifugally separating the dirt or the dirty liquid based on the centrifugal force acting at the time of rotation but also by mechanical processing. The active element can have bristles that can be constructed to be flexible or rigid and/or scrape edges or the like. Furthermore, the scraping device can be connected in a rotationally fixed manner to the rotatable additional shaft such that the scraping device or the actuating element rotates relative to the regeneration chamber or the cleaning element arranged therein. The scraping device can be rotated and/or deflected, for example, in the same or opposite direction as the rotating shaft body. The scraping device may in particular correspond to a motor drive device that causes the scraping device to rotate and/or deflect. Alternatively, the scraping device can also passively rotate with one another when the rotating shaft body or the cleaning element rotates based on the friction fit, wherein the direction of rotation of the scraping device is opposite to the direction of rotation of the rotating shaft body.

In addition to the aforementioned regeneration unit, the invention also proposes a cleaning element for a wet cleaning apparatus, wherein the cleaning element is a cleaning cylinder having a central gap, a drum core and a drum jacket, wherein the drum core has a spacing a fabric, and wherein the drum jacket has a layer of fine fibers. This combination of materials absorbs dirt and dirt well during the cleaning process of the wet cleaning equipment. On the other hand, the material can also discharge dirt or dirt well during regeneration of the cleaning element. In addition, the proposed material can dry out quickly. Furthermore, the spacer fabric is in particular provided with a hydrophobic coating, such as PTFE (polytetrafluoroethylene). This allows for optimal regeneration when the cleaning element is rotated. The central gap is used to connect the cleaning element to the rotating shaft of the regeneration unit. Preferably, the cleaning element has a cylindrical cavity, together with a connecting member that causes the cleaning element to be rotationally coupled to the receiving area of the rotating shaft body.

Finally, the invention also proposes a kit of a regeneration unit of the aforementioned type and a cleaning element of the aforesaid type, wherein the cleaning element is rotatably coupled to the rotating shaft of the regeneration unit. In particular, the regenerative unit and the cleaning element are designed in a corresponding manner in terms of shape and size, so that the cleaning element arranged on the rotary shaft body in the regeneration chamber is rotated toward the scraping device, so that the aforementioned mechanical cleaning of the cleaning element can take place. Furthermore, the features and advantages described with respect to the regenerative unit or the cleaning element are correspondingly applicable to this kit.

Figure 1 is a perspective perspective view of the independent regeneration unit 1 from the outside, wherein the internal area of the regeneration unit 1 is also visible. 2 is a longitudinal sectional view of the regeneration unit 1.

The regeneration unit 1 is substantially cylindrical. The regeneration unit 1 has a base 26 which is constructed below the regeneration chamber 4 for accommodating the cleaning elements 2 during the operation of the regeneration unit 1 in the orientation shown in the regeneration unit 1. The base 26 has a control unit 27 which (primarily) cooperates with the cable 24 and the plug 25 to control the power supply of the regeneration unit 1. Also disposed in the susceptor 26 is a liquid pump 16 for inputting clean liquid from the clean liquid chamber 9 to the regeneration chamber 4. A clean liquid dispensing device 11 providing a fluid connection 10 is disposed between the clean liquid chamber 9 and the regeneration chamber 4. The clean liquid dispensing device 11 has a plurality of discharge openings 12 introduced into the regeneration chamber 4, which respectively correspond to nozzles for spraying clean liquid into the regeneration chamber 4 in the liquid discharge direction 13.

A rotary shaft body 6 rotatable by the electric motor 15 of the regeneration unit 1 is disposed in the regeneration chamber 4. Arranged on the circumferential surface 7 of the rotating shaft body 6 are two receiving regions 8 for the cleaning element 2 to be connected to the rotating shaft body 6. The accommodating area 8 has a rib 31 for holding the cleaning element 2 in the direction of the longitudinal extent of the rotating shaft body 6.

A battery 21 that can be used for the autonomous operation of the regeneration unit 1 is arranged in the rotating shaft body 6. When power is supplied through the battery 21, it is not necessary to connect the regeneration unit 1 to the household power source through the cable 24 and the plug 25.

In the regeneration chamber 4, a scraping device 17 is arranged on the inner wall of the casing 3 of the regeneration unit 1. The scraping device 17 is parallel to the longitudinal extent of the rotating shaft body 6. The scraping device 17 has an active element 18, here a scraping edge constructed along the entire longitudinal extent of the rotating shaft body 6. The scraping device 17 projects from the inner wall of the housing 3 into the regeneration chamber 4, i.e., in the direction of the rotating shaft body 6.

The regeneration unit 1 has a clean liquid chamber 9 that can be taken out from the casing 3 and a dirt collection chamber 5 that can be taken out from the casing 3. The clean liquid chamber 9 has a clean liquid joint 22. The collecting chamber 5 has a dirty liquid connection 23. In the region of the clean liquid joint 22 or the dirty liquid joint 23, a handle 32 is formed on the clean liquid chamber 9 or the dirt collection chamber 5.

The regeneration unit 1 has a system composed of three mutually independent chambers, that is, a regeneration chamber 4, a dirt collection chamber 5, and a clean liquid chamber 9. The chambers are connected back and forth in such a way that the clean liquid can proceed from the clean liquid chamber 9 into the regeneration chamber 4, where the cleaning element 2 connected to the rotating shaft body 6 is regenerated and the accumulated dirt is self-regenerated. The chamber 4 is sent to the collecting chamber 5. The liquid enters the regeneration chamber 4 through the fluid connection portion 10 constructed between the clean liquid chamber 9 (or the liquid pump 16) and the regeneration chamber 4. The heating device 14 corresponding to the clean liquid chamber 9 can heat the clean liquid in the clean liquid chamber 9, for example, to more than 60. The temperature of C in order to eliminate bacteria, fungi and the like in clean liquids. A fluid connection 10 constructed below the regeneration chamber 4 is likewise arranged between the regeneration chamber 4 and the collection chamber 5. The dirty liquid passes through the fluid connection portion 10 from the regeneration chamber 4 based on the hydrostatic pressure to enter the dirt collection chamber 5. The liquid pump 16 is used to input the clean liquid from the clean liquid chamber 9 to the regeneration chamber 4. The liquid pump 16 is independently operated by the battery 21 if it is not powered by the cable 24 and the household wiring.

Figure 3 shows a cross section of the regeneration unit 1 along the line III in Figure 2 . The drive mechanism of the regeneration unit 1 can be seen for rotating the rotary shaft 6 in the regeneration chamber 4. The drive mechanism includes a gear mechanism having a ring gear 28 constructed on an inner wall of the hollow rotating shaft body 6 and a gear 29 meshing with the ring gear. The gear 29 is disposed within the rotating shaft body 6 and has a drive connection toward the electric motor 15. When the electric motor 15 is in operation, the gear 29 rotates, and the rotating shaft body 6 rotates due to the engagement with the ring gear 28. On the outer side of the rotating shaft body 6, a plurality of guiding rods 30 are formed, one side of which is connected to the rotating shaft body 6 in a rotationally fixed manner, and the other side is slid along the inner wall of the regeneration chamber 4, for example, by a sliding connection. In this way, it is ensured that the rotating shaft body 6 is centered in the regeneration chamber 4.

Figure 4 shows an exploded view of the regeneration unit 1 in which components that are separable from the regeneration chamber 4 are shown. Separate from the regeneration chamber 4, there is mainly a clean liquid chamber 9, a dirt collection chamber 5, a susceptor 26 and a scraping device 17 having a clean liquid dispensing device 11. A liquid pump 16 and a control device 27 are arranged in the base 26. The control device 27 is for controlling the liquid pump 16, the electric motor 15, and the heating device 14.

FIG. 5 shows the regeneration unit 1 together with the cleaning elements 2 arranged in the regeneration chamber 4. The cleaning element 2 here is a cleaning drum of the wet cleaning device having a drum core 19 and a drum jacket 20. The drum core is constructed of a spacer fabric that provides a plurality of cavities for absorbing liquid. In addition, the spacer fabric is hydrophobic and coated with PTFE. The drum coat 20 is a layer of fine fibers which absorbs dirt and dirt during cleaning by the cleaning element 2. The cleaning element 2 is constructed in a cylindrical shape and also has a cylindrical void in which the rotating shaft body 6 can be accommodated. During the regeneration operation of the regeneration unit 1 as shown in Fig. 5, the cleaning element 2 is held on the accommodating area 8 of the rotary shaft body 6. For this purpose, the ribs 31 which are formed on the accommodating area 8 are snapped into corresponding grooves (not shown) of the cleaning element 2. In this way, a friction-resistant connection is produced between the cleaning element 2 and the rotating shaft body 6.

In a state where the cleaning member 2 is housed on the rotating shaft body 6, the action member 18 of the scraping device 17 is caught in the fiber of the drum casing 20. Therefore, during the rotation of the rotating shaft body 6 and the rotation of the cleaning member 2, the drum casing 20 is scraped on the scraping device 17, thereby mechanically separating the dirt and the liquid from the drum casing 20. Further, the dirt and the dirty liquid are centrifugally separated from the cleaning element 2 based on the rotation of the cleaning element 2 or the centrifugal force acting, and penetrate the fluid connection portion 10 to enter the dirt collection chamber 5. During the regeneration, the cleaned liquid delivered by the heating device 14 and the clean liquid delivered by the liquid pump 16 is also sprayed from the discharge opening 12 of the clean liquid dispensing device 11 to the surface of the cleaning member 2, thereby the dirt self-cleaning member 2 The fine fiber layer is removed. The washed, centrifuged or scraped sewage together with the solid soil component enters the collection chamber 5 through the fluid connection 10. The collection chamber 5 can be taken out from the regeneration unit 1 and emptied as needed.

Figure 6 shows a cross section of the regeneration unit 1 of Figure 5 in a cross-sectional plane along line VI. The arrangement of the regeneration chamber 4, the cleaning element 2 and the rotating shaft body 6 having the ring gear 28 and the gear 29 can be seen. Furthermore, it can also be seen that the scraping device 17 has its active element 18 snapped into the fibers of the drum casing 20 of the cleaning element 2. The scraping device 17 is here arranged in a rotationally fixed manner on the housing 3 of the regeneration unit 1 . However, as an alternative (although not shown), the scraping device 17 can likewise be constructed and arranged to be rotatable such that the actuating element 18 is pivoted, for example, in the same clockwise direction as the cleaning element 2, so that the cleaning element A reverse movement occurs in the contact zone between the scraping device 17 and the scraping device 17, which also increases the mechanical force acting on the cleaning element 2 and optimizes the regeneration.

Finally, Fig. 7 shows another embodiment of the regeneration unit 1 of the present invention, wherein the construction of the clean liquid distribution device 11 differs from the embodiment shown in Figs. The clean liquid dispensing device 11 spirally surrounds the cleaning element 2 and has a plurality of discharge openings 12 which are placed differently with respect to the longitudinal extent of the cleaning element 2 and the circumferential direction of the cleaning element 2. Location. If the clean liquid dispensing device 11 is not disposed (as shown) in the regeneration chamber 4, it is instead embedded in the housing 3 of the regeneration unit 1 such that only the discharge opening 12 projects into the regeneration chamber 4.
