    专利说明:

    This object is achieved with a evaporation device according to the present invention as stated in the independent claims.
    Thus, in accordance with a first aspect of the present invention, there is provided an evaporation device comprising a handle, a flexible, elongate cleaning member connected to the handle, and an elongate guide member having a first end fixed to a top of the cleaning element. The guide element is arranged along and inside the cleaning element and has a second end, which is arranged to be accessible at the handle. A controlled. bending of the said cleaning element is effected by applying a tensile force to the other end.
    This offers a convenient way to control the bending of the cleaning element by pulling the free end of the control element. The guide element can be one / one of a string, a rod, a spring and a rubber element. The cleaning device is advantageous for cleaning otherwise difficult-to-access places, such as heating elements, and in or around ceiling-mounted luminaires, with a control of the bending of the cleaning element according to the needs of the situation.
    In accordance with an embodiment of the cleaning device, the cleaning element is resilient. Due to the resilience of the cleaning element, the cleaning element returns completely to its original shape when the traction force acting on the control element ceases or decreases, or, as in the case where the traction force is reduced, it returns to its original shape. This also has the advantage of giving, within predetermined maximum and minimum limit values determined, for example, by the material in the cleaning element and by its construction, a continuous bending of the bending of the cleaning element by application of a suitable tensile force.
    In accordance with an embodiment of the cleaning device, the cleaning device also comprises an operating element which is arranged at the handle. The other end of the control element is attached to the operating element. The operating element is arranged to provide traction forces on the other end when it is operated. With the control element an increased control and repeatability of the bending of the cleaning element can be provided. The operating element can be arranged in different ways, for example so that the operation of the control element is performed by moving the operating element towards the free end of the handle, pressing a key or moving the operating element in a direction different from the normal pulling direction of the control element.
    In accordance with an embodiment of the cleaning device, the operating element is arranged at a predetermined position on the handle in order for a bending of the cleaning element with a one-handed operation to be possible. By placing the control element in a suitable position relative to the free end of the handle, a user can hold the cleaning device in one hand and reach the control element with one or two fingers. As a result, the user has a one-handed grip to effect the bending of the cleaning element.
    This is advantageous, for example, when the user dusts off a luminaire in the ceiling and extends the arm to reach the area to be dusted. The bending of the cleaning element is suitably initiated. at. needs' and. with. use of the hand holding the cleaning device, so that it is not necessary to interrupt the cleaning activity.
    In accordance with an embodiment of the cleaning device, the cleaning device also comprises a locking element for locking the control element in an equipped condition, which is advantageous since the bending is then maintained without the user having to hold the control element in the operated position.
    In accordance with an embodiment of the cleaning device, the handle also comprises a telescopic unit inside which the guide element is arranged. The extendable handle increases the usable area reached by the cleaning device.
    In accordance with an embodiment of the cleaning device, the telescopic unit is fixed in a advanced state by means of balanced friction between telescopically arranged parts of the said telescopic unit, which is advantageous.
    In accordance with an embodiment of the cleaning device, the telescopic unit is fixed in an equipped condition by means of at least one set of a spring-loaded projection and a corresponding hole arranged on adjacent telescopically arranged parts, which is advantageous.
    In accordance with an embodiment of the cleaning device, the cleaning element is hollow and the telescopic unit is arranged to fit into the cleaning element in a returned condition. When the telescopic unit is not in use, it can be fully inserted into the cleaning element, which means a compact solution that takes up minimal space.
    In accordance with an embodiment of the cleaning device, the cleaning element comprises a fiber unit which is arranged on a fiber holder. The fiber unit includes cleaning fibers. Thus, there is a cleaning element in which the fiber unit and the fiber holder are separate parts. In the case of a spring dust rocker, for example, cleaning fibers are twisted together with a steel wire into an indivisible unit. In this inventive concept, the fiber holder can be removably arranged on the fiber holder in such a way that the fiber holder can be replaced or washed between uses. The separate arrangement also allows different choices and combinations of functional materials when choosing the fiber holder and the fiber unit.
    In accordance with an embodiment of the cleaning device, the fiber holder is a soft tubular element. In addition to being flexible, a soft inner part of the cleaning device is advantageous compared with, for example, an ordinary spring dust rocker solution, where cleaning fibers are twisted together with a steel wire to form the spring dust rocker. In the latter, a surface that is being cleaned may be inadvertently scratched by the steel wire solution. The soft inner part of the cleaning device according to the invention according to the present inventive idea results in a safe cleaning of delicate surfaces with little risk of scratching the surface.
    In accordance with an embodiment of the cleaning device, the fiber holder is a rubber hose which can be folded, which is advantageous. A rubber hose that is folded in the longitudinal direction of the hose facilitates bending of the cleaning element.
    According to an embodiment of the cleaning device, the material of the cleaning device is selected to provide charging of the cleaning element with static electricity when rubbed against a second selected material.
    This is advantageous because electrostatic charging of the cleaning element increases the cleaning capacity of the cleaning device. that the ability to attract and retain dust particles is improved.
    In accordance with an embodiment of the cleaning device, at least a part of the cleaning element is arranged removably with respect to the handle, which provides an opportunity to wash that part of the cleaning element when the cleaning device is not in use. The removably arranged part of the cleaning element can be attached to the cleaning device by means of a velcro lock or any other suitable fastening device.
    In accordance with a second aspect of the invention, a cleaning system is created comprising a cleaning device and a chamber for housing the cleaning device.
    The chamber can be connectable to a suction source, which is advantageous for removing dust from the cleaning device in connection with the cleaning device being placed and stored in the chamber. The system can be arranged in any suitable vacuum cleaner. Realization of the evaporation system in a vacuum cleaner entails advantages in addition to those explained above in terms of whether the cleaning system itself and conveniently, since the user can then choose to use the cleaning device instead of using the vacuum cleaner hose and nozzle and in a smooth and user-friendly manner. reach and clean surfaces on which normal vacuuming is not suitable.
    The vacuum cleaner can be of any type of suitable vacuum cleaner, for example a floor vacuum cleaner, a bagged or unleashed vacuum cleaner, an upright vacuum cleaner or a central vacuum cleaner.
    These and other aspects, features and advantages of the invention will be apparent from and illustrated with reference to the embodiments described below.

    Description of Preferred Embodiments Embodiments of the present inventive concept will now be described in more detail with reference to the accompanying drawings which show certain embodiments of the invention. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments shown herein; these embodiments are given rather as examples for this description to be detailed and complete and to fully convey to those skilled in the art the scope of the invention. Identical reference numerals generally refer to like elements.
    In an embodiment of a cleaning device 10 which is shown in cross section in the schematic side view in Fig. 1a), the cleaning device 10 has a handle 20 on which a bottom part 31 of a flexible cleaning element is arranged.
    The cleaning element 30 here is a microfiber cloth. The cleaning device further comprises a guide element 40, which may be one or either of a wire, a string, a rod, a spring and a rubber element or any other suitable element.
    A first end 41 of an elongate guide member 40 is further attached to an upper portion 32 of the cleaning member 30 and extends within the cleaning member 30 to the upper portion 31 of the cleaning member 30. The second end 42 of the wire is thus accessible to a user who can hold handle 20 and operate the guide member 40 by pulling the guide member 40 in a direction away from the cleaning member 30. The upper portion 32 of the cleaning member is thereby forced into a bend shown in Fig. 1b). The cleaning element 30 is arranged to be resilient to spring back to or against its original shape. when the traction applied at. operation of the control element is removed resp. reduced.
    The basic idea is thus that the flexible cleaning element is forced to bend when operating the guide element which is attached to the upper part of the cleaning element. The degree of bending of the cleaning element is related to the magnitude of the tensile force applied to the control element when it is operated.
    In an embodiment of cleaning device 11, which is shown in the schematic side view in Fig. 2a) and has a similar basic arrangement as that of the cleaning device 10 described with reference to the schematic side view in Figs. 1a) and b), the handle 20 is arranged to be hollow or at least to have a void channel. Thereby, the guide element 40, which is attached to the upper part 32 of the cleaning element 30 and arranged to run inside the cleaning element 30, can enter the handle 20 and run inside the handle 20 to an operating element 43 on which the other end 42 of the guide element 40 is fixed. The operating element 43, shown in Fig. 2c), comprises a plate 45 with a central opening 48 having substantially the same diameter and profile as the shaft 21 of the handle 30 and through which opening 48 the shaft 21 is inserted at the assembly of a such that the plate 45 is arranged perpendicularly and movably, while at the same time surrounding the shaft 21. A guide piece 49, which is arranged on the plate 45, projects radially and inwards towards the center of the shaft 21 and is arranged to run in the movement of the plate 45 in a groove 22 arranged in the wall of the shaft 21. The groove 22 has a predetermined length and determines the possible positions of the operating element 43. The groove 22 is preferably arranged in such a way that in an initial position of the operating element 43 the cleaning element 30 is relaxed and no force is applied to the guide element 40. When the user moves the operating element 43 from the initial position by pulling the plate 45 along the groove 22 towards the free end of the handle 20, the dizzying element 40 and the cleaning element 30 is bent.
    In a. embodiment of the cleaning device which. is shown in the close-up in Fig. 2c), the control element 43 is also provided with a locking element 44 for locking the operating element 43 and thus also the control element 40 in an operated condition. The locking element 44 here is a spring-loaded projecting part 44 which locks in a corresponding hole 46 arranged in a suitable predetermined position in the shaft of the handle 20.
    The position of the hole 46 is preferably determined. of the appropriate maximum extension of the guide member 40 and the desired corresponding bend of the cleaning member 30.
    It should be mentioned that in addition to this example, any suitable arrangement of locking elements can be used.
    In an embodiment of the cleaning device 12 shown in the cross-sectional view in Fig. 3, the initial position of the operating element 43 is adapted to be within reach of the fingers of a hand which maneuvers the cleaning device 12. Thereby it is possible to operate the cleaning element 30 with a hand. The user holds a handle 27 which is arranged at the free end of the handle 20 and at the same time reaches the operating element 43 with, for example, the index finger and the middle finger. When it is desired to bend the cleaning element 30, the user simply pulls the operating element towards the handle 27, whereby the cleaning element is bent.
    Furthermore, a closing element 28 is arranged at the handle 20. The closing element 20 is designed to form an air seal when the cleaning device is inserted. in a chamber for storage. In the embodiment of a cleaning device shown in the close-up of a handle in Fig. 3, the closing element 28 is conical. The conical surface of the closing element 28 provides a good air seal between the cleaning device and the chamber, but other shapes can also be used.
    The cleaning device 12 shown in Fig. 3 further comprises a telescopic unit 50. The telescopic unit 50 is a hollow arrangement of telescopically arranged parts, 52, 53, 54, which together form an elongate shaft on the handle 20.
    In one embodiment of the cleaning device. son is shown in Fig. 4a), the telescopic unit 50, when in an extended state, is fixed by balanced friction, i.e. with friction elements 51 arranged between the telescopically arranged parts 52, 53 of the telescopic unit 50 to provide friction to keep the telescopically arranged parts fixed. A retraction of the telescopic unit 50 is obtained by applying a retraction force which is greater than the balanced frictional force on the telescopic parts.
    In an embodiment of the cleaning device which. is shown in Fig. 4b), the telescopic unit 50 is fixed in an extended state by means of at least one arrangement of a spring-loaded projecting part 56 and a corresponding hole arranged on adjacent telescopically arranged parts 52, 53. The spring-loaded radially projecting part 56 automatically locks the the telescopic parts 52, 53 when the hole 55 is in a position in front of the projecting part 56. In order for the telescopic part to be retracted, either a return force greater than a threshold force caused by the spring force and the hole is applied or alternatively, the user releases the protruding portion 56 by pressing the protruding portion 56 inwardly against the telescopic portion and at the same time retracts the telescopic portions of the guide member 40, which is fixed to the upper portion 32 of the cleaning member 30 and arranged to run inside the cleaning member 30. , is further permitted to enter the handle 20, where it runs inside the telescopic unit 50 for maneuver the spring element 43, to which the other end 42 of the guide element 40 is fixed. The guide element 40 is here a flexible wire.
    The elongate cleaning element here comprises a fiber holder 35, on which a fiber unit 34 is arranged.
    The fiber unit 34 has fibers suitable for collecting dust. In the embodiment shown in Fig. 3, the fiber holder is a flexible, soft tubular element, and the telescopic unit 50 is arranged to fit into the fiber holder 35 in a retracted position. The fiber holder 35 is thus arranged to act as a telescopic part. together with the adjacent telescopic part 52 in a manner similar to that described above for the telescopic parts 52, 53, 54 of the telescopic unit 50. This means that the fiber holder 35 can receive and accommodate the telescopic part 52 The telescopic unit 50 is usually housed in the fiber holder when the cleaning device is not in use.
    As has been mentioned, the fiber holder 35 here is a soft tubular element, for example a rubber hose, which can be folded to promote the bending of the hose when the operating element 43 is activated for the cleaning element to bend.
    In alternative embodiments of the cleaning device, the fiber unit is permanently attached. on the fiber holder, for example when long fibers are twisted with steel wire to form the cleaning element. In other embodiments, the cleaning element can be realized as a piece, for example when the fiber holder itself contains the cleaning fibers, as in a tubular or cylindrical microfiber unit.
    In embodiments of the cleaning device, the fiber unit is further arranged to be removable or replaceable.
    The fiber unit can then be removed to be washed or replaced with a fiber unit with the same or a different material. The fastening of the fiber unit is in embodiments of the cleaning device realized with a Velcro fastener (not shown) or other suitable fastening devices.
    As mentioned above, the cleaning device can be arranged in a chamber for storage, and the cleaning device and the chamber then form a cleaning system in accordance with the present inventive idea. In an embodiment of a cleaning system, the material of the cleaning element 30 is selected in such a way that when the cleaning fibers are rubbed against each other or alternatively against the side walls of the chamber, a charge with static electricity is obtained. The material of the cleaning fibers and the walls of the chamber are optimized for each other to provide high charging speeds. Materials that are suitable for providing high charging speeds are, for example, microfiber materials, such as a polyethylene blend provided by Starfibre or Aquaster.
    The chamber for storing the cleaning device may be arranged in a vacuum cleaner 50, as shown in Fig. 5, which is a schematic perspective view of an embodiment of the evaporation system according to the present inventive concept. The cleaning system 60 comprising a cleaning device 13 and a corresponding chamber 10 is shown with the cleaning device 13 fully extended and located outside the chamber 10. In this embodiment, the cleaning device 13 is a spring dust rocker with a handle 20 on which an elongate cleaning element 30 is arranged. An operating element 43 is arranged at the handle 20 in a manner similar to that described above for the embodiment of the cleaning device in Fig. 3, with the difference that the handle 20 in this embodiment does not comprise a telescopic unit. A handle 27 is provided at the free end of the handle 20, and further, a closure member 28 provided at the handle provides an airtight closure of the chamber 10 at the chamber opening 23 when the cleaning device is inserted into the chamber 10 at the chamber opening 23.
    The chamber 10 is arranged to fit the cleaning device 13 and has a cleaning chamber 11, which is arranged at its entrance, for example the opening 23, into which the cleaning device is inserted when it enters the chamber 10. The cleaning chamber 11 further has a outlet 12 intended to facilitate fluid communication. between the chamber and a suction source (not shown) in the vacuum cleaner 50 in which the cleaning system is arranged. The suction source can alternatively be realized with connection to a central vacuum cleaner or realized with a fan unit and a dust collector as an integral part of the evaporation system, so that an independent and possibly mobile evaporation system is obtained.
    The chamber 10 also has a storage room 15 which is arranged adjacent to the cleaning room 11 and opposite the opening 23. The chamber. is further arranged so that the cross-sectional area A2 of the cleaning space 11 in a plane perpendicular to the extent of the chamber 10 is sufficiently large to allow the fibers of the cleaning part to move freely and thereby facilitate removal of dust and particles from the part of the cleaning device which is located in the cleaning room 11 and is exposed to the suction force which the suction source provides. Furthermore, the cross-sectional area A1 in the cleaning room is smaller than the cross-sectional area of A2 in the cleaning room. This means that the cleaning element 30 is compressed when it is introduced into the storage room 15.
    The cross-sectional profile of the cleaning room is preferably kept as even as possible and is arranged to have the same diameters over the entire length of the cleaning room so that turbulent air flow and generation of unwanted noise when air flows through the cleaning room 11 is to be avoided.
    In the foregoing, embodiments of the evaporation system according to the present inventive concept as expressed in the appended claims have been described. They are only to be regarded as non-limiting examples. As will be appreciated by those skilled in the art, many modifications and alternative embodiments are possible within the scope of the invention.
    It is to be noted that for the purposes of this application, and in particular with respect to the claims, the word "comprising" does not exclude other elements or measures and steps, and that the word "one" or "one" does not exclude a plural, which in and per se is obvious to those skilled in the art.
