Definitions

  • the invention relates to a cleaning device for wet mopping with a device for dispensing liquid.
  • the range of a mop cover, and consequently the area to be cleaned with a mop cover can be increased by the covering to be cleaned being re-wetted during the cleaning process.
  • the wetting is triggered manually by the user.
  • Multi-part handles that can be extended and retracted telescopically are known both with regard to easier stowage on the cleaning trolley and to individual adjustment to the height of the user, which is advantageous from an ergonomic point of view.
  • telescopic handles consist of two or more tubes of different diameters, which are pushed into one another and can be fixed to one another in different positions.
  • handle constructions in which such a fixation is only possible in certain positions of the tubes relative to one another, and those handle constructions, which allow a fixation in allow any tube configuration and thus the desired length of the telescopically extendable handle.
  • Telescopically extendable handles that can be fixed in defined positions often have a spring-loaded pin in the inner tube, which can be pushed radially into the inner tube through a hole under pressure, allowing free displacement of the two tubes relative to each other.
  • the outer tube has a plurality of holes arranged in the longitudinal direction of the handle, the diameter of which corresponds at least and approximately to that of the pin. If the pivot is brought into a matching position with one of these holes by twisting and shifting the tubes relative to one another, the spring mechanism of the pivot causes it to snap into a hole and thus fix the handle in its position.
  • telescopic handles are known in which the locking takes place by twisting one tube about the longitudinal axis of the handle relative to the other tube, which allows stepless adjustment of the handle length.
  • the fixation of the handle is achieved by a locking device that is arranged between the two tubes and is usually designed as an eccentric mechanism.
  • a telescopically length-adjustable handle is known in which two individual elements can be continuously displaced relative to one another in the longitudinal direction and can be adjusted with the aid of a locking device that can be actuated in a simple manner.
  • the object of the invention is to provide a cleaning device for wet wiping with a water tank, with the help of which the surface to be cleaned can be re-wetted, to be designed in such a way that it can be equipped with a telescopic handle.
  • the cleaning device for wet mopping comprises a telescopically adjustable handle in the longitudinal direction, a device attached to the handle for dispensing liquid with a reservoir for liquid, at least one dispensing opening for liquid, a first fastening device which is firmly attached to a first end in the longitudinal direction of the handle and second attachment means slidably attached to the handle relative to the longitudinal axis of the handle.
  • the cleaning device also includes a cleaning head which has means for detachably attaching a mop cover.
  • the handle By attaching the liquid dispensing device to the second attachment means so as to be slidable relative to the longitudinal axis of the handle, the handle can be telescopically adjusted in the longitudinal direction without the necessary displacement movement being impeded by the liquid dispensing device attached to the handle .
  • This special attachment according to the invention has the additional advantage that, in use, the handle can also be used to actuate the device for dispensing liquid.
  • the device for dispensing liquid comprises a first housing section and a second housing section which is movable relative to the first housing section, the The volume of a liquid chamber in the device for dispensing liquid can be changed by moving the second housing section relative to the first housing section, the liquid chamber being in liquid communication both with the dispensing opening and with the reservoir.
  • variable-volume liquid chamber can thus be used like a pump chamber, so that with a defined reduction in the volume of the liquid chamber, the amount of liquid displaced by the volume reduction can be dispensed through the at least one dispensing opening.
  • the first housing section and the second housing section are preferably designed such that the second housing section can be moved in the longitudinal direction of the handle relative to the first housing section between a first position and a second position and is prestressed into the first position by an elastic element.
  • the liquid chamber can automatically return to its original volume, so that only a single actuating movement is required for the targeted dispensing of liquid. Since the liquid chamber is also in liquid communication with the reservoir, liquid can also flow from the reservoir into the liquid chamber as soon as the second housing section is returned to the first position by the action of the elastic element, in which the volume of the liquid chamber is increased again.
  • the second attachment device of the device for dispensing liquid is attached to the handle so that it can slide relative to the longitudinal axis of the handle, not only can a change in length of the handle be compensated for during the telescopic adjustment in the longitudinal direction of the handle, but the second housing section can also be actuated with the aid of the handle , because the relative movement between the handle and the second fastening device is possible due to the slidable design of the second fastening device.
  • the cleaning device is preferably designed in such a way that the device for dispensing a liquid further comprises a non-return valve between the liquid chamber and the reservoir.
  • the second fastening device is a collar which encloses the telescopically adjustable handle.
  • a cuff has several advantages. For one, it is a very simple component. Furthermore, the provision of a collar which encircles the handle with little play will fix the position of the liquid dispensing device in every direction except with respect to the longitudinal direction of the handle. Finally, the desired telescopic function of the adjustable handle is possible without any problems and the pump function provided according to a preferred embodiment of the invention using the handle can also be implemented.
  • the at least one dispensing opening for liquid is preferably designed in the form of a spray nozzle.
  • a spray nozzle By providing a spray nozzle, the liquid to be dispensed can be dispensed in a defined area, so that the desired subsequent wetting of the mop takes place more evenly than when the liquid is dispensed only at certain points.
  • the spray nozzle is arranged so that the liquid is discharged in a substantially unidirectional direction adjacent to the cleaning head. In this way, the liquid hits the surface to be cleaned next to the cleaning head so that it can either act there for pre-treatment or is placed for subsequent absorption by the mop cover.
  • a pump tappet is provided on the second housing section of the device for dispensing liquid, which is slidably guided in a pump tappet receptacle in the first housing section of the device for dispensing liquid in the longitudinal direction of the handle.
  • the desired pressure pulse can be generated by a longitudinal displacement of the second housing section relative to the first housing section, which is suitable for dispensing a precisely defined quantity of liquid through the at least one dispensing opening.
  • the cleaning device is configured such that the cleaning head is articulated to the liquid dispensing device.
  • one end in the longitudinal direction of the handle can be fixed to the second housing section of the liquid dispensing device, while the cleaning head is hinged to the first housing section of the liquid dispensing device.
  • the distance between the in the region of the first housing section arranged spray nozzle and the surface to be cleaned always the same and the dispensing of liquid can be easily effected by a user by pressing the handle and thereby moving the second housing section in the direction of the first housing section.
  • the cleaning device is preferably designed in such a way that the handle, which can be adjusted telescopically in the longitudinal direction, can be moved between a first position, in which the length of the handle is between the first end and the second end is variable, and a second position in which the length of the handle between the first end and the second end is not variable.
  • the handle comprises two handle elements which can be continuously adjusted relative to one another in the longitudinal direction of the handle and which can be releasably fixed to one another by means of a locking device, the locking device comprising two components which are arranged along the longitudinal direction of the handle around the longitudinal axis of the handle are rotatably connected to each other.
  • a locking device comprising two components which are arranged along the longitudinal direction of the handle around the longitudinal axis of the handle are rotatably connected to each other.
  • the cleaning device 10 has a handle 12 which has a first end 14 and a second end 16 in the longitudinal direction. At the second end 16 a handle 18 is provided.
  • the cleaning device 10 has a device for dispensing liquid which is attached to the handle 12 is.
  • the device 20 for dispensing liquid has a reservoir 22 for cleaning liquid, which is provided with a sight glass 24 for checking the fill level and a filler neck 26 .
  • the cleaning liquid in the reservoir 22 is in flow communication with a later based on the figure 4 pump chamber explained in more detail and is discharged via a spray nozzle 28 when the cleaning device 10 is actuated accordingly by the user.
  • the spray nozzle 28 is, as in the 3 is shown, is arranged centrally and its inclination relative to the handle is adjusted in such a way that the cleaning liquid is dispensed onto the surface to be cleaned in an area in front of a cleaning head 30 .
  • the cleaning head 30 is connected to the liquid dispensing device 20 by means of a joint 32 .
  • the cleaning head 30 can be designed in a conventional manner in order to clamp a mop cover, which is not shown in the figures.
  • suitable folding mechanisms can be provided, as are customary in cleaning devices of this type.
  • Actuating elements 34 are indicated schematically, with the aid of which the cleaning head 30 can be actuated in a way that is ergonomic for the user.
  • the handle is telescopically adjustable in the longitudinal direction and can be switched between an extended position, which is 1 is shown and in which the handle extends beyond the liquid dispensing device 20 by the length L1, into which in 2 be brought into the position shown, in which the handle 12 extends over the device 20 for dispensing liquid only by the lesser length L2.
  • the device 20 for dispensing liquid is only firmly connected to the handle at its first end, which faces the cleaning head, with the aid of a first fastening device 36, while a second fastening device 38 of the device 20 for Delivery of liquid is designed so that the handle 12 is slidably guided in the second attachment means 38, so that in the Figures 1 and 2 shown adjustment of the handle is possible.
  • the longitudinal adjustment of the handle can be accomplished in any manner known in the art. However, it is preferred to design the adjusting mechanism in such a way that a rotation about the longitudinal axis X of the handle 12 releases the telescopically extendable handle and locks it again after a corresponding longitudinal adjustment.
  • the 3 is a front view of the in 1 Illustrated cleaning device 10 is shown to show that the reservoir 22 is arranged so that it extends in the longitudinal plane of the handle 12 so as not to produce lateral imbalance.
  • the second fastening device 38 is designed in the form of a cuff 40, which extends around the handle 12 with little play and completely encloses the handle, so that only a sliding movement of the handle 12 in the direction of arrow B relative to the cuff 40 is possible.
  • the handle 12 is firmly connected at its first end 14 to the device for dispensing liquid 20 , the device 20 having a first housing section 42 and a second housing section 44 .
  • the second housing section 44 is firmly connected to the first end 14 of the handle 12.
  • the second housing section 44 is mounted in the first housing section 42 so that it can be displaced in the direction of the longitudinal axis X of the handle and has a pressure pump piece 46 which can be displaced in a suitable pump tappet receptacle 48 and, when the second housing section 44 is displaced relative to the first housing section 42 in the direction of the arrow D the volume in a liquid chamber 50 decreases. If the volume of the liquid chamber 50 is now reduced by a displacement of the second housing section 44 in the direction of arrow D and the action of the pressure pump piece 46 in the receptacle 48, pressure builds up. The pressure cannot escape towards the reservoir 22 because there is a check valve 52 in the flow connection between the reservoir 22 and the liquid chamber 50 . Thus, when the second housing section 44 is displaced in the direction of arrow D, pressure builds up in the liquid chamber and liquid is released in a targeted manner through the spray nozzle 28.
  • a stop is provided, with the aid of which the distance of the maximum displacement movement of the second housing section 44 relative to the first housing section 42 is fixed.
  • an elastic element in the form of a spring is provided, which returns the second housing section 44 counter to the direction of arrow D into a starting position, which is always assumed when the user is not exerting any pressure on the handle 12 in the longitudinal direction.
  • the spring 54 guides the second housing section 44 back to the starting position counter to the direction of arrow D, as a result of which the volume of the liquid chamber 50 increases and a vacuum is created. Liquid can then flow into the liquid chamber via the reservoir 22 and is thus ready for the next targeted dispensing of a defined quantity of liquid.
  • FIGS Figures 5a and 5b The actuation of the cleaning device 10 according to the invention when the spray nozzle 28 is actuated, as illustrated above, is shown schematically in FIGS Figures 5a and 5b shown.
  • the handle 12 By a small lifting movement of the handle 12 in the direction of arrow D, which is shown schematically with H, the handle 12 is abruptly pressed down by the user if necessary to develop the pumping effect, which is based on the Fig.4 was explained.
