    DESCRIPTION:
    FIELD OF THE INVENTION
    The invention relates to a cleaning device for cleaning a cylindrical filter, comprising: a frame, a spindle rotatably connected to the frame with its external thread, a nozzle holder present on the spindle, which nozzle holder is provided with an opening with internal screw thread which cooperates with the external screw thread of the spindle, locking means securing the nozzle holder against rotation with respect to the frame, a filter carrier rotatable about its axis, and a nozzle connected to the nozzle holder on the filter carrier in the presence of the filter center line of the filter is aimed at the filter, so that the filter will rotate around the center line through the jet of water from the nozzle.
    More in particular, the invention relates to an apparatus for cleaning a cartridge filter that is frequently used in a bubble and / or massage bath, in a swimming pool or in a pond.
    State of the art.
    Such a device is generally known. In the known device, the spindle is driven by an electric motor which must be connected to a power outlet via an electricity cord.
    Summary of the invention.
    An object of the invention is to provide a device for cleaning a filter that does not require electricity to function properly. To this end, the device according to the invention is characterized in that it further comprises a transmission between the filter carrier and the spindle, which is designed such that when the filter carrier is rotated about its axis, the spindle is rotated about its axis via the transmission. During operation, the water jet from the spray head will rotate the filter because it is directed from the center towards the filter. The filter carrier rotates with the filter and drives the spindle so that the nozzle holder moves over the spindle along the filter. Thus, the spray head moves axially along the rotating filter, so that the entire jacket surface of the filter comes into contact with the water jet.
    An embodiment of the cleaning device according to the invention is characterized in that the cleaning device comprises switching means which direct the water jet on the other side of the center line of the filter on the filter, so that the filter and via the transmission also rotate the spindle in the opposite direction. The advantage of the presence of switching means is that the nozzle holder automatically returns to the starting position during cleaning, whereby the filter is also sprayed clean a second time and the water jet hits the filter at a different angle, so that the filter is cleaned better.
    A further embodiment of the cleaning device according to the invention is characterized in that a further spray head is connected to the spray head holder, which further spray head is directed at the part of the filter on the other side of the center line of the filter than the part of the filter on which the nozzle is oriented so that when switching from spraying with the spraying head to spraying with the further spraying head the filter and via the transmission also the spindle will rotate in the opposite direction. Due to the presence of two nozzles, the nozzle does not have to be rotated, but only the water supply between the nozzles has to be controlled.
    A still further embodiment of the cleaning device according to the invention is characterized in that the two nozzles are connected to a cylinder open at both ends, the two nozzles being spaced apart in the axial direction of the cylinder and between the two nozzles the cylinder is provided with a connecting piece for connecting an external water hose, and that the switching means comprise a piston slidable in the cylinder, which piston is provided with a middle part with an end part on either side thereof, the middle part having a smaller diameter than the end parts that have a have a diameter that is at least substantially the same as the inside diameter of the cylinder, which piston is movable between two extreme positions, wherein in one of the extreme positions the piston protrudes with one of the end parts from one of the ends of the cylinder and in the other extreme position the piston with the other end part from the other end of the cylinder protrudes, the middle part having such a length that the middle part is always at the location of the connecting piece and, in the presence of the piston in an extreme position, the middle part is also at the location of the nozzle and not at the location of the further nozzle and in the presence of the piston in the other extreme position, the middle part is also located at the location of the further nozzle and not at the location of the nozzle. Reliable, robust and compact switching means are obtained in this way.
    Yet another embodiment of the cleaning device according to the invention is characterized in that the filter carrier is formed by two rollers which are parallel and spaced apart by a diameter smaller than the diameter of the filter and which run horizontally during operation and on which the filter is present during operation . This makes the cleaning device suitable for filters with a large range of different diameters. Moreover, the filters can easily be placed loose on the rollers and there is no need to fix the filters on the filter carrier.
    Yet another embodiment of the cleaning device according to the invention is characterized in that a nut is present in the opening of the nozzle holder which is displaceable in the axial direction and is fixed in tangential direction with respect to the nozzle holder, wherein between each end of the opening and the nut has an axially acting spring. When the direction of movement is switched, the spindle can still be driven as a result of the inertia of the mass, while the nozzle carrier is present in an end position. This does not lead to problems because the nut can be displaced slightly in the axial direction against a spring force.
    Brief description of the drawings.
    The invention will be explained in more detail below with reference to exemplary embodiments of the cleaning device according to the invention shown in the drawings. Hereby shows:
    Figure 1 shows a schematic view of an embodiment of the cleaning device according to the invention in top view;
    Figure 2 shows the cleaning device in side view;
    Figure 3 shows the nozzle holder of the cleaning device in perspective;
    Figure 4 shows the nozzle holder dismantled; and
    Figure 5 shows the nozzle holder in longitudinal section.
    Detailed description of the drawings.
    Figures 1 and 2 show an embodiment of the cleaning device 1 for cleaning a cylindrical filter 3 in top and side view, respectively. The cleaning device 1 has a frame 5 and a spindle 7 rotatably connected about its axis 7b with external screw thread for displacing a nozzle holder 9 present on the spindle along the filter. The nozzle holder is provided with an opening 11 with internal screw thread which cooperates with the external screw thread of the spindle. Locking means 13 in the form of a fork which is slidable over a rod 14 prevent the nozzle holder from rotating relative to the frame. Attached to the nozzle holder 9 are two nozzles 19 and 21 which are directed at different parts present on different sides of the axis 3b of the filter 3, so that the filter will rotate about the axis 3b through the water jet from the nozzles.
    The cleaning device 1 furthermore has a filter carrier which is formed by two parallel and spaced apart rollers 15 and 17 which are rotatable about their axis 15b, 17b. The cleaning device 1 is furthermore provided with a transmission 23 between one of the filter carriers 17 and the spindle 7. This transmission is formed by two gear wheels which engage each other. Upon rotation of the filter carrier 17 about its axis 17b, the spindle 7 will rotate about its axis 7b via the transmission 23.
    The cleaning device 1 is furthermore provided with switching means which direct the water jet on the other side of the axis 3b of the filter 3 onto the filter, so that the filter and via the transmission 23 also the spindle 7 start rotating in the opposite direction. When switching from spraying with the spray head 19 to spraying with the further spray head 21, the filter 3 and via the transmission 23 also the spindle 7 will start rotating in the opposite direction.
    3-5, the nozzle holder 9 of the cleaning device is shown in various views. The two nozzles 19 and 21 are mounted on the lateral surface of a cylinder 25 open at both ends. The nozzles are spaced apart in the axial direction of the cylinder. Between the two nozzles 19 and 21, the cylinder is provided with a connecting piece 27 for connecting an external water hose.
    The switching means are formed by a piston 29 which is slidable in the cylinder 25 and which is provided with a middle part 29a with an end part 29b and 29c on either side thereof. The middle part 29a has a diameter that is smaller than the end parts 29b and 29c which have a substantially equal diameter than the inner diameter of the cylinder 25. The piston 29 is movable between two extreme positions, wherein in one of the extreme positions the piston with one of the end parts 29b protrudes from one of the ends 25a of the cylinder and in the other extreme position the piston with the other end part 29c protrudes from the other end 25b of the cylinder.
    The middle part 29a has such a length that the middle part is always at the location of the connecting piece 27 and, in the presence of the piston 29 in an extreme position, the middle part 29a is also located at the nozzle 19 and not at the location of the further nozzle 21 and in the presence of the piston 29 in the other extreme position the middle part 29a is also located at the location of the further nozzle 21 and not at the location of the nozzle 19.
    A nut 31 is present in the opening 11 of the nozzle holder 9, see figure 3, which is movable in the axial direction and is fixed in tangential direction with respect to the nozzle holder. Between each end of the opening 11 and the nut there is a spring 33a, 33b acting in the axial direction so that the nut can move slightly in the axial direction against a spring force.
    Although in the foregoing the invention has been elucidated with reference to the drawings, it should be noted that the invention is by no means limited to the embodiment shown in the drawings. The invention also extends to all embodiments deviating from the embodiment shown in the drawings within the scope defined by the claims.
