  • the user can use the display and input device, for example, to portion the dispensing quantity of the disinfectant from the disinfectant dispensing device and/or to set the dispensing number of towels from the towel dispensing device for drying the hands. It is also conceivable for the user to use the display and input device to enter, for example, an evaluation of satisfaction with regard to the state and equipment of the sanitary facility in the vicinity of which the hygiene station is set up or installed.
  • the room scent dispensing device can be arranged above the towel dispensing device so that it can supply or fill the installation site of the hygiene station with a room scent as much as possible.
  • the room scent can be released either at fixed intervals or via a sensor assigned to the room scent release device, which detects the number of users and/or their length of stay in the vicinity of the hygiene station and regulates the room scent release depending on this.
  • the compression and/or crushing device according to the invention can be arranged below the disinfectant dispensing device into which the user can throw or feed used towels.
  • the housing of the towel dispensing device is preferably located between the disinfectant dispensing device and the room fragrance dispensing device, with the dispensing opening of the towel dispensing device being arranged at the level of the output of the disinfectant dispensing device and opposite the insertion opening of the compacting and/or crushing device.
  • the compression and/or crushing unit has at least two counter-rotating rollers arranged parallel to one another.
  • the counter-rotating rollers or rollers arranged parallel to one another rotate in such a way that a towel thrown in or brought in and used from the outside or above is conveyed between the rollers into the interior of the receptacle.
  • the rollers are preferably of the same length and have the same diameter. However, it is also possible that the diameter of the two rollers is different.
  • the rollers are made of a rigid or hard-to-deform material, such as stainless steel or ceramic.

  • the rings or, but also the grooves and/or nubs of a roller can be machined, whereby the rings and roller consist of one workpiece.
  • the rings can also be slid onto the roll and fastened at a predetermined position along the longitudinal axis of the roll. In the case of separate rings, these can either be of the same material as the roller or of a different material.
  • the rings preferably have the same diameter. In one possible embodiment, the rings are uniformly and equidistantly spaced.
  • the rings are spaced equidistantly along the longitudinal axis of the rollers.
  • the rings have a smaller spacing in a middle section of the rollers if the design of the feed area of the compacting and shredding device increases the probability that the used towels fed in reach the rollers first in this area.
  • the rings are integrally formed on the respective roller.
  • rollers do not have any weak points along their circumference that could give way during compaction and crushing.
  • the rings of the rollers are arranged in such a way that one ring of one roller is opposite an intermediate space between two rings of the other roller.
  • rollers By arranging the rings in the spaces between the rings of the other roller, optimal compaction and shredding performance is ensured.
  • the rollers are arranged in the gaps in such a way that they do not touch either the roller body of the opposite roller or its rings, which prevents wear on the rollers and rings.
  • the depth of engagement of the rollers in the gaps between the rings of the opposing roller can be made adjustable to suit the nature of the towels being provided to ensure that the rollers do not jam during compaction and shredding.
  • the rollers have circular knives arranged on the outer circumference.
  • the circular knives or cutting edges on the outer circumference of the rings improve the shredding result of the used towels to be shredded.
  • the cover element prevents accidental reaching into the compression and/or crushing unit, especially by children. Thus, a used only be fed into the manual once the insertion opening has been released. At the same time, the cover element prevents shredded towels from overflowing, provided that the compacting and/or shredding unit does not fill the entire feed opening of the container.
  • At least one displaceable or foldable cover element can be provided on the upper side of the cover element inside or outside in order to release and close the insertion opening again.
  • This at least one cover element can be moved via a further drive unit. In the case of a displaceable cover element, this is guided on two sides in rails, along which it can open and close the insertion opening again.
  • the cover element preferably comprises slats which are pivotably connected to adjacent slats on the long sides and are guided in rails on the narrow sides.
  • the rails extend in a first area near the deposit opening in a direction that forms an angle of less than 45° to a horizontal plane, with the lower ends of the rails in particular facing the position of a person using the hygiene station.
  • these preferably extend in a direction that forms an angle of less than 15°, in particular 0°, to a vertical plane.
  • the two sections of each rail are connected to one another via a curved section. When the slot is closed, the slats are in the first area of the rails and when the slot is open, they are in the second area.
  • the cover element and the receptacle preferably have the same shape along the touching edges, with the cover element resting on the receptacle in the region of the feed opening of the receptacle such that the interior is sealed or essentially enclosed.
  • the cover element can also be in the area of the feed opening of the Receptacle can be pushed along two rails provided there, wherein the pushed-on cover element can be locked or arrested in its position over the feed opening of the receptacle.
  • the cover element has a funnel element which is arranged below the insertion opening and is designed in such a way that it guides towels that have been brought in to the compacting and/or shredding unit.
  • cleaning elements can be provided on the side of the compressing and/or shredding unit pointing towards the interior of the receiving container, which cleaning elements free the compressing and/or shredding unit from sticking residues of the towels.
  • the cleaning elements can be strips which extend along the longitudinal axis of the rollers and are arranged at a small distance below the rollers in such a way that they strip or remove residues of the compacted and reduced towels adhering to the rollers from the rollers. These strips are aligned in such a way that the residues that have been stripped off or removed can also get into the receptacle.
  • the strips can be made of plastic or metal or any other suitable material.
  • the device comprises a sensor and a controller which is connected to the sensor and controls the opening and re-closing of the insertion opening.
  • the sensor detects that a used towel is to be fed in and forwards the recorded feed request to the controller, whereupon the latter activates the drive unit of the cover element so that the insertion opening can be released.
  • the control activates the drive unit of the cover element again in order to close the throw-in opening again.
  • the controller is configured in such a way that the opening is either left open for a certain period of time or until it receives another signal from the sensor.
  • the senor is arranged on an outer surface of the device.
  • the sensor can be provided as an optical sensor.
  • An optical sensor such as a light sensor or optical detector, is a simple variant for recognizing a user's wish to throw in a used towel and forwarding it to the controller.
  • a light barrier can also be implemented as an optical sensor, which forwards an electrical signal to the controller when the light beam is interrupted and forwards another signal to the controller as soon as the receiver of the light barrier receives the light beam again.
  • the towels that reach the compression and/or shredding unit through the insertion opening can have very different shapes. They may be slightly deformed and thus essentially flat or formed into a compressed ball of paper. In terms of moisture content, too, they can range from completely dry to dripping wet. Experiments have shown that these large differences also lead to completely different behavior when entering the compression and/or comminution unit and to different levels of contamination of the compression and/or comminution unit, or impairment of their function.
  • the compacting and/or comminuting unit is assigned a pressing device which can be moved by a pressing drive unit between two end positions at different distances from the compacting and/or comminuting unit.
  • the pressing device makes it possible to press towels against the compression and/or shredding unit. This pressing is important for particularly dry, ball-shaped or flat towels, because these do not get between the rollers without pressing despite the rotating rollers.
  • the pressing device is important for trouble-free operation of the compression and crushing device.
  • the rollers comprise a large number of circumferential rings projecting in the radial direction, the rings being arranged or designed on the rollers in such a way that one ring of one roller in each case has a free space next to a ring of the other roller intervenes.
  • the directly adjoining rings of two cooperating rollers overlap, so that the associated edges of the rings cut the material of the towels in the overlapping area.
  • the rings have a rough surface radially on the outside so that the material of the towels is well drawn into the free spaces and conveyed through them towards the receiving container and compressed in the receiving container that is already loosely filled.
  • the rough surface is in the form of a knurl.
  • Advantageous knurling includes ridges extending along the axes of the rollers.
  • the rough surface or the knurling ensures that dry and wet, ball-shaped or flat towels are drawn into the compression and/or shredding unit with good contact to the entry area of the rollers and that the shredded material of the towels also faces a great deal of resistance in the Receptacle is promoted.
  • the fill level of the receptacle is displayed. This enables the service personnel to close the receiving container in good time to empty.
  • the filling level can optionally be displayed via a viewing window. Because the comminuted material of the towels, even when loose, can essentially fill the entire receptacle, information that is dependent on the overall density of the material in the receptacle is preferably displayed as the filling level.
  • the maximum filling level is associated with a maximum permissible material density in the receiving container.
  • at least one pressure or force detection device is arranged on the receiving container, which makes it possible to detect and in particular display the fill level.
  • a force absorbed by a partial boundary surface of the receptacle corresponding to the filling level or the pressure in the receptacle can be recorded and displayed.
  • a pressure detected on the partial boundary surface, or a deformation of the partial boundary surface or the deflection of the partial boundary surface caused against a prestress is detected.
  • At least one pressure sensor is preferably arranged on the receptacle. It is advantageous if a pressure sensor is arranged at least on a partial area of the bottom of the receptacle. If necessary, the at least one pressure sensor is arranged on a wall of the receptacle or if necessary in the comminution unit, for example in the vicinity of the rollers.

  • the sensor 122 of the cover element 108 is arranged above the cover element 120 in such a way that it can detect the delivery request, i.e. a hand approaching with a used towel, and then sends a signal to the control 124.
  • the controller 124 then activates the cover element 120, which releases the insertion opening 116, and the drive unit 106, which drives the rollers 128 of the compression and/or crushing unit 104.
  • the user can dispose of or throw the used towel into the throw-in opening 116.
  • the used towel is then fed via the funnel element 118 to the compression and/or shredding unit 104, which compresses and shreds it and conveys it in the direction of the interior 114 of the receptacle.
  • the controller activates the drive module (not shown) of the cover element 120 so that the cover element 120 closes the insertion opening 116 again.
  • the cover element 120 can additionally or alternatively be pushed open manually by a user and closed again after the used towel has been thrown in.
  • a handling element is formed in the area of the front edge of the cover element 120 pointing upwards, which the user can take to move the lid member 120.
  • the cover element 120 can be held in the closed position by springs. The user then has to move the cover element 120 against the spring force in order to release the insertion opening 116 . When the cover element 120 is released, it snaps back into the closed position due to the spring force and thus closes the insertion opening 116 again.
  • FIGS. 3 and 4 The compacting and/or comminuting device 100 from FIG. 1 is shown in FIGS. 3 and 4 without a receiving container 102 .

  • the cover element 120 has a rolling element 132 on both sides at the level of its front edge and its rear edge. The rolling elements 132 engage in the respective guide rails 130 and enable the sliding of the cover element 120 along the guide rails 130.
  • FIG. 5 shows the plan view of the compression and comminution device according to the invention from FIG.
  • the design of the rollers 128 can be seen, which have rings or rollers 134 spaced equidistantly in the longitudinal direction.
  • the rings 134 may have been turned from a roll 128 with an initial diameter equal to the diameter of the rings 134 such that the respective roll 128 and its rings 134 are integral. However, the rings 134 can also have been pushed onto the respective roller 128 and fixed at a predetermined position.
  • gaps 136 are formed between each two rings 134.
  • the two rollers 128 in FIG. 5 are arranged in such a way that the rings 134 engage in the gaps 136 of the opposite roller 128 without the opposite roller 128 or its rings 134 are contacted.
  • the engagement depth of the rings 134 in the gaps 136 is adjustable, so that the compression and/or shredding unit 104 can be adjusted to the nature of the towels to be compressed and shredded.
  • the drive unit 106 drives the rollers 128 via a gearwheel arrangement 138 in such a way that they rotate in opposite directions about their longitudinal axes.
  • the design of the funnel 118 over the entire width of the compacting and/or crushing unit 104 ensures that all used towels that have been thrown in are fed to the compacting and/or crushing unit 104 without separating used towels being thrown into one fallen into the dead area and thus cannot reach the receptacle 102 compacted and crushed.
