Definitions
- the invention relates to a device for ejecting liquid from a wiper body, which is held to form a wiping surface on a wiper head of a surface cleaning device, with a container in which a wiper body holder receiving the wiper body and a drive device are arranged, the wiper body holder being arranged by means of the drive device an axis of rotation is drivable.
- a wiping body for example a wiping pad or a wiping covering, which is held on a wiping head to form a wiping surface, is often used to clean a soiled surface, in particular a floor surface.
- the wiping body is moved with its wiping surface along the surface to be cleaned and dirt is thereby absorbed.
- the wiper body is then usually washed out and wrung out.
- WO 92/14394 A proposes to place the wiper body on a wiper body holder, which is then set in rotation so that liquid is thrown out of the wiper body due to the centrifugal forces acting on it.
- Such a procedure has the advantage that the user does not come into contact with the cleaning liquid.
- the known device requires not inconsiderable energy consumption in order to reliably dehumidify the wiping body.
- the object of the present invention is to develop a device of the type mentioned at the outset in such a way that the dehumidification of a wiper body can be carried out with less energy consumption.
- the wiper body holder forms a receptacle into which the wiper body can be inserted with the surface normal of the wiping surface oriented at an angle to the axis of rotation.
- the wiper body holder holds the wiper body with an angular, ie oblique or perpendicular to the axis of rotation wiping surface within the container, i.e. H. the surface normal of the wiping surface is not aligned parallel to the axis of rotation, but is at an angle to the axis of rotation. It has been found that liquid droplets can be thrown out particularly effectively by such an alignment of the wiping surface.
- the device according to the invention is consequently characterized by a higher efficiency. This makes it possible to achieve effective dehumidification of the wiper body even at relatively low speeds and consequently with relatively low energy consumption.
- the receptacle receives the wiping body with the surface normal of the wiping surface oriented perpendicular to the axis of rotation. This enables a particularly compact form of the spinner.
- plate-shaped wiping bodies can be dehumidified in an advantageous manner, which form a wiping surface both on their top side and on their underside and can therefore be used on both sides.
- wipers are usually on a Nem wiper body holder held on the side of a handle or handle.
- the wiper body carrier with the wiper body held thereon can be pivoted relative to the handle such that, alternatively, the top or the underside of the wiper body carrier faces the surface to be cleaned.
- This pivotable mounting of the wiper body carrier on the handle makes it easier to insert the wiper body carrier together with the wiper body held thereon into the receptacle of the wiper body holder such that the surface normal of the wiper surface is oriented perpendicular to the axis of rotation of the ejection device.
- the receptacle comprises a guide into which the wiper body can be inserted.
- the guide facilitates the insertion of the wiper body.
- the guide preferably has two U-shaped guide elements that run parallel to one another and hold the wiper body between them.
- the guide elements are preferably held at the opposite ends of a guide support aligned parallel to a bottom surface of the container.
- the wiper body can be inserted particularly easily into the receptacle of the wiper body holder if the guide elements are aligned parallel to the axis of rotation.
- the wiper body holder can be rotated manually.
- the drive device coupled to the wiper body holder can have mechanical drive elements with a user of the ejection device operated crank or a foot pedal. It is particularly favorable if the drive device has mechanical deflection elements for deflecting a translatory movement of the foot pedal into a rotational movement of the wiper body holder.
- the drive device comprises a drive motor, preferably an electric motor.
- the drive motor is assigned a rechargeable energy supply unit. This enables the centrifugal device to operate independently without the need to ensure a mains supply.
- the drive device is arranged inside the container below the wiper body holder and preferably at a distance from a bottom wall of the container.
- the area below the drive device can consequently serve as a receiving space for the liquid ejected from the wiper body.
- the drive device on the bottom wall of the container, the drive device not covering the entire area of the bottom wall, so that a receiving space for the ejected liquid can be provided on the side next to the drive device within the container.
- the drive device held on the bottom wall can also be positioned at a distance from the wiper body holder, forming the receiving space between the two components. It is advantageous if the speed of the wiper body holder is adjustable. This makes it possible to set different speeds depending on the desired degree of moisture that the wiping body is to have after spinning. For example, a selector switch can be provided with which the user can select a specific speed.
- the speed is continuously adjustable, for example in a range between 250 revolutions per minute and 500 revolutions per minute.
- a maximum spin time of the wiper body holder can be specified, after which the rotary drive of the wiper body holder can be switched off automatically.
- the user can use a selector switch to choose between different spin times. In particular at a given speed, the selection of the spin time gives the user the opportunity to adjust the degree of moisture of the wiper body as required.
- the wiper body holder has a switching element which, after the wiper body has been inserted into the wiper body holder, activates the rotary drive.
- a key switch is preferably used as the switching element. It has proven to be particularly favorable if the switching element is based on can be actuated smoothly, for example it can be designed as a reed contact.
- the use of a switch which can be actuated manually by the operator of the ejection device can be provided, for example in the form of a main switch or emergency stop switch.
- the wiper body holder is coupled to the drive device via a slip clutch. This enables the wiper body holder to be held in place when the drive device is active, without there being any risk of injury.
- the container comprises a partition for dividing the container into a centrifugal area receiving the wiper body holder and a washing area receiving a cleaning liquid for washing the wiper body. This gives the user the opportunity to first immerse the wiper body several times in the cleaning liquid during cleaning and thus to wash the wiper body. The wiper body can then be inserted into the wiper body holder in the centrifugal area and set in rotation to eject the cleaning liquid.
- the centrifugal area receives both the wiper body holder and the drive device.
- the Drive device positioned within the washing area and is connected via coupling elements to the wiper body holder arranged in the centrifugal area.
- the device comprises a spray device for spraying the wiping body inserted into the wiping body holder.
- a spray device for spraying the wiping body inserted into the wiping body holder. This makes it possible to spray the wiping body with cleaning liquid, while at the same time rotating it. It can be provided, for example, that the wiper body is first rotated at a low speed and at the same time sprayed with cleaning liquid, and that the cleaning liquid is then thrown out of the wiper body at a higher speed.
- the spray device preferably comprises at least one spray nozzle which is in flow connection with a feed pump. It is advantageous here if liquid can be pumped from the area below the wiper body holder to the spray nozzle by means of the feed pump. This means that liquid which was spun out of the wiping body in a previous spinning process can be sprayed onto the wiping body for washing in a subsequent spinning process.
- the spinner device comprises a storage chamber for unused cleaning liquid and if liquid is pumped from the storage chamber to the spray nozzle by means of the feed pump. that can. This allows the wiper body to be sprayed with unused cleaning liquid for washing.
- the container of the centrifugal device can be closed by means of a container lid. This not only reduces the risk of a user accidentally reaching into the container during the rotation of the wiper body holder, but it also enables the drive device to be switched on and off depending on the position of the container lid by the container lid having an electrical switching element interacts.
- the container lid can be hinged to the container, for example, and the switching element can be designed as a button that switches on the drive motor when the container cover is closed and that switches off the drive motor when the container cover is opened.

- FIG. 6 a diagrammatic representation of an alternative embodiment of a floor wiper device with a collapsible wiper body
- FIG. 7 shows a diagrammatic representation of a fourth embodiment of a device for ejecting liquid from the wiper body according to FIG. 6.
- a floor wiper device 10 known per se is shown in a schematic representation with a handle 11 which is connected via a joint 12 to a wiper head in the form of a plate-shaped wiper body carrier 13, on the underside of which is remote from the handle 11, a wiper body 14 is fixed.
- the latter can be a wiping covering, for example, which can be separated from the wiper body support 13.
- the wiper body 14 With its underside facing away from the wiper body carrier 13, the wiper body 14 forms a wiping surface 15 which can be moved along a floor surface to be cleaned for dirt collection and the alignment of which is predetermined by a surface normal 16 oriented perpendicular to the wiping surface 15.
- Floor surfaces can be cleaned in the usual manner by means of the floor mopping device 10.
- the wiping body 14 is moistened and then moved along the floor surface to be cleaned, so that, for example, dust can be picked up from the floor surface.
- the wiping body 14 is then washed out and wrung out, so that it only has a low degree of moisture.
- the device for ejecting liquid from the wiping body 14, shown schematically in FIG. 2 and denoted overall by the reference number 20, is used according to the invention. It comprises a container 21 with a centrifugally shaped centrifugal area 22 which is separated from a washing area 24 by a partition 23.
- the wiper body carrier 13 with the wiper body 14 held thereon can be inserted into a wiper body holder 26 within the centrifugal area 22 and then rotated so that the liquid absorbed by the wiper body 14 is subjected to a centrifugal force and is largely thrown out of the wiper body 14.
- the structure of the centrifugal device 20 is particularly clear from the sectional view according to FIG. 3.
- diametrically opposite two supports 30, 31 are fixed on the inner wall of the container 21, which accommodate a watertight housing 33 of a drive device 34 between them.
- the supports 30 and 31 form for this purpose, not shown in the drawing, known grooves, into which the housing 33 inserted from above and can also be removed if necessary.
- the drive device 34 comprises an electric drive motor 36 which is coupled via a pulley 37 and a toothed belt 38 to a toothed belt pulley 39 which is held on a drive shaft 40 in a rotationally fixed manner.
- the drive shaft protrudes with its end facing away from the toothed belt pulley 29 via a cover 42 of the housing 33 and carries an intermediate piece 43 via a sliding clutch 44 which is known per se and is therefore only shown schematically in the drawing, on which a wiper body holder 45 is seated, which rotates with the Intermediate piece 43 is connected.
- the wiper body holder 45 comprises two parallel, U-shaped guide parts 46, 47, which are rigidly connected to one another via a cross member 48 connected to the intermediate piece 43 in a manner fixed against relative rotation.
- the guide parts 46 and 47 define a receptacle 49 of the wiper body holder 45, into which the wiper body carrier 13 together with the wiper body 14 held thereon can be inserted in the vertical direction.
- the drive shaft 40 is resiliently mounted in the axial direction, so that the wiper body holder 45 held on the drive shaft 40 via the slip clutch 44 and the intermediate piece 43 can be moved in the direction of the waterproof housing 33 against an elastic spring force.
- a pushbutton switch 51 Arranged between the crossbeam 48 of the wiper body holder 45 and the housing 33 on the upper side of the housing is a pushbutton switch 51, which is connected to the electric motor 36 via known electrical lines (not shown in the drawing).
- the key switch 51 can by moving the Wiper body holder 45 are actuated in the direction of the housing 33.
- a contactless proximity switch for example a reed contact
- a contactless proximity switch could be arranged inside the waterproof housing 33, which can be actuated by the wiper body holder 45 approaching the housing 33.
- waterproof electrical feedthroughs through the housing 33 to a switching element positioned outside the housing could be dispensed with.
- two rechargeable batteries 52 are arranged within the housing 33 of the drive device 34, which enable the ejection device 20 to operate independently.
- the energy supply takes place via a connection cable which can be connected to a mains supply.
- the drive shaft 40 can be set in rotation about its longitudinal axis by means of the electric motor 36, i. H. the longitudinal axis of the drive shaft 40 defines an axis of rotation 55 of the centrifugal device 20.
- the axis of rotation 55 is aligned coaxially with the axis of symmetry of the circular-cylindrical centrifugal region 22.
- the wiper body carrier 13 with the wiper body 14 held thereon is inserted into the receptacle 49 of the wiper body holder 55 in such a way that the surface normal 16 of the wiper surface 15 is oriented perpendicular to the axis of rotation 55.
- the pushbutton switch 51 can be actuated, as explained above. This causes the electric motor to be switched on and the wiper body holder 45 to be set in rotation via the drive shaft 40.
- the liquid absorbed by the wiper body 14 is subjected to a centrifugal force, so that it is thrown out of the wiper body 14 in the radial direction and strikes the inside of the wall of the container 21.
- the flung-out liquid then flows along the container wall in the direction of the bottom wall 57 of the container 21.
- the centrifugal area 22 forms a liquid receiving space 59, in which the space from the wiper body 14 ejected liquid collects.
- the energy supply to the electric motor 36 is interrupted and the rotational movement is thus ended.
- the wiper body carrier 13 can be removed together with the wiper body 14 of the receptacle 49 of the wiper body holder 45.
- the speed of the wiper body holder 45 can be continuously adjusted by the user between a value of about 250 revolutions per minute to about 500 revolutions per minute, so that the user can specify the degree of moisture of the wiping body 14 after the centrifuging process has taken place.
- a rotary switch known per se and therefore not shown in the drawing is used, which is connected to a control unit 61 of the drive device 34 arranged inside the housing 33. is coupled.
- the speed of the drive motor 36 can be set continuously by means of the control unit 61.
- the container 21 includes a washing area 24 in addition to the centrifuge area 22.
- Unused cleaning liquid can be poured into the washing area 24 for washing the wiping body 14. For this purpose, this is immersed several times within the washing area 24 in cleaning liquid.
- the wiper body 14 can then be dehumidified in the centrifugal area 22.
- FIG. 4 A second embodiment of a centrifugal device according to the invention is shown in FIG. 4 and overall designated with the reference number 65. This has largely the same structure as the ejection device 20 explained above. For identical components, the same reference numerals are therefore used as in FIGS. 1, 2 and 3. In this regard, reference is made in full to the above statements.
- the spinner 65 differs from the spinner 20 shown above with reference to FIGS. 2 and 3 in that a separate washing area 24 for washing the wiping body 14 is omitted. Instead, the centrifugal device 65 has a spray device 67 with a spray nozzle 69 fixed at the level of the guide parts 46, 47 on the inside of the wall of the container 21.
- the spray nozzle 69 is connected via a hose 70 to a feed pump 71 arranged on the bottom wall 57 inside the liquid-receiving space 59 flow connection. By means of the feed pump 71, liquid can be sucked out of the liquid receiving space 59 and pumped to the spray nozzle 69.
- the user has the option of inserting the wiper body carrier 13 together with the wiper body 14 into the wiper body holder 45 and first spraying cleaning liquid during a slow rotation of the wiper body holder 45 in order to wash out the wiper body 14.
- the speed of the wiper body holder 55 can then be increased, at the same time the feed pump 71 being switched off, so that the wiper body 14, as explained above, can be dehumidified.
- FIG. 5 shows a further embodiment of an ejection device according to the invention, which is denoted overall by reference numeral 75. It differs from the above-described ejection device 65 only by the additional use of a container lid 76, which is articulated on the top of the container 21 and has a radially extending receiving slot 77 through which the stem 11 of the floor mopping device 10 can pass after the wiper body carrier 13 was inserted together with the wiper body 14 into the wiper body holder 45.
- the container 21 can be closed by means of the container lid 76, so that the risk of liquid escaping from the container 21 or that the user accidentally reaches into the container 21 during the rotation of the wiper body holder 45 is reduced.
- the use of the container lid 76 also gives the possibility, instead of the pushbutton switch 51, of using a button, not shown in the drawing, which cooperates with the container lid 76 and can be actuated by the container lid 76. If the container lid 76 is closed, the electric motor 36 is switched on via the button, and the electric motor is switched off when the container lid is opened.
- the wiper body carrier 13 is designed in the manner of a plate or frame, and the linkage of the handle 11 to the wiper body carrier 13 takes place in the region of a transverse edge of the wiper body carrier.
- FIG. 6 shows an alternative embodiment of a floor mopping device, which is also known per se, and is identified overall by reference numeral 80. It also includes a handle 81 which is held on a wiper body carrier 83 via a joint 82. The latter is designed in two parts and comprises two support halves 84, 85 which are coupled to one another via a hinge 86 which can be locked by the user. On its underside, the wiper body carrier 83 carries a wiper body 87 which, facing away from the handle 81, defines a rectangular wiper surface 88 with a surface normal 89.
- the handle 81 can be pivoted upward into a position aligned parallel to the surface normal 89, and the user can then release the known locking mechanism of the hinge 86, not shown in the drawing, so that the two carrier halves 84 and 85 can be pivoted upwards in the direction of the handle 81.
- the wiper body carrier 83 with carrier halves 84 and 85 pointing obliquely upward and surface normals 89 of the wiper body 87 oriented obliquely to the axis of rotation 55 can then be inserted into a corresponding wiper body holder of a fourth embodiment of a spout device 95 according to the invention shown in FIG.
- the spinner 95 is the same as above with reference to FIG Figure 4 explained ejection device 65 largely identical. It is therefore shown in a highly simplified manner in FIG. It differs from the ejection device 65 only in the special adaptation of the wiper body holder 45 to the collapsible wiper body carrier 83. As already explained, the two carrier halves 84 and 85 can be pivoted upwards. This gives the possibility of inserting the areas of the wiping surface 88, each associated with a carrier half 84 or 85, with surface normals 89 oriented obliquely to the axis of rotation 55 into the wiper body holder of the ejection device 95.
- the wiper body carrier 83 is rotated together with the wiper body 87 held thereon for dehumidification, as already explained above. Due to the foldable design of the wiper body carrier 83, the ejection device receiving the wiper body carrier 83 can be designed to be very compact and with a small overall size.
