Definitions

  • the invention relates to a self-propelled cleaning device, in particular for swimming pools, with a basic housing in which a drive for the cleaning device is integrated and at least one cleaning brush and an intake duct is provided, via which liquid to be cleaned can be conveyed into a filter space by means of a pump.
  • EP-A 0 099 489 shows a cleaning device of this type, in which rotating cleaning brushes are provided on both sides of a basic housing, the liquid to be cleaned being sucked in and transported into a filter which is seated on the basic housing.
  • the drive is switched over and the driving direction of the cleaning device is changed, if necessary, by means of appropriate sensors.
  • This cleaning device works excellently, but has a large flow resistance due to its high filter structure.
  • the patent EP-A-0 257 006 describes a self-propelled cleaning device for swimming pools, in which a filter bag is used to clean the polluted water, which results in a high filter space and a correspondingly high flow resistance. In addition, the cleaned water escapes from the filter fabric in an uncontrolled manner, with undesirable turbulences that impair cleaning.
  • the preamble of claim 1 is known from document EP-A-0 257 006.
  • the object of the present invention is to develop a cleaning device of the type mentioned above, which is of compact construction and improved in terms of flow technology and in which an improved suction and filtering of the liquid to be cleaned is ensured.
  • This cleaning device does not have a high filter structure, so that the flow resistance is reduced and energy is saved during the operation of the cleaning device.
  • the aesthetic design is also improved.
  • the housing cover is connected to the basic housing via a hinge. If this housing cover is lifted off, the filter space and the filter mat lying in this filter space are freely accessible. This filter mat can be easily cleaned or replaced.
  • the filter mat preferably rests in the filter space in wedge channels which are molded into the basic housing. These V-shaped channels can run across or parallel to the longitudinal axis of the housing and enable the filtered water to be drained over a large area.
  • a connection piece opens into the filter chamber, which is connected to a central chamber.
  • the pump is arranged in this central chamber.
  • the pump is preferably a vortex pump, which is non-positively connected to the housing drive, i.e. is connected to the engine or a gear part.
  • the pump must rotate in both directions, i.e. can promote both forwards and backwards.
  • Channels lead from the central chamber to corresponding suction openings which are assigned to the cleaning brush. These channels preferably run at an angle to the longitudinal axis of the housing, as a result of which there is a high cross flow from both sides to the suction openings.
  • the cleaning brush is connected to the basic housing via a lever joint.
  • This lever joint can be arranged in the center and be designed as a gimbal.
  • the lever joint is also designed so that the cleaning brush can adjust unevenness in the pelvic floor. It is also used for this that the cleaning brush preferably consists of two brush rollers which are arranged on the side of the lever joint and which can be moved separately.
  • the cleaning brush should preferably be connected to the drive of the cleaning device itself, for example to correspondingly driven wheels. This can be done using timing belts.
  • an additional cross brush together with the cleaning brush includes a suction space in the direction of travel to the rear. This also improves the corresponding intake flow.
  • a cleaning device R according to the invention for swimming pools has a basic housing 1 which is designed to be mobile. Driving takes place on corresponding, possibly profiled, conveyor belts 2 arranged on both sides of the basic housing 1, which are endless and are placed over two spaced wheels 3 and 4 or deflection rollers. A band guide 6 is provided between the two wheels 3 and 4 towards the driving surface 5.
  • this belt guide 6 presses a tension roller 7 onto the conveyor belt 2.
  • the conveyor belts 2 arranged on both sides are preferably caterpillar-shaped.
  • an axle 8 of the rear wheels 3 should preferably be driven.
  • a motor is provided for this drive 9, which is only shown schematically in FIG. 1.
  • the motor can be connected to the axis 8 via a gear 10.
  • a power unit and control logic are also provided for the motor.
  • a floating cable is connected to a connector 17 indicated in FIG.
  • a contact strip 18 is attached to the basic housing 1, which, for example, reports a contact with a wall of the swimming pool to the control logic.
  • a switch bar 20 is located on the rear wall 19 of the housing 1, which can also cause the drive 9 to switch to forward or reverse travel.
  • this is only mentioned by way of example and is not the subject of the present invention.
  • this cleaning brush 21 is connected to the basic housing 1 by a lever joint 22 arranged approximately in the center.
  • This suspension enables the cleaning brush 21 or the brush roller 23 and 24 to adapt to unevenness in the pelvic floor.
  • Each brush roller 23 or 24 is still cut by toothed belts 27, which ensure that the cleaning brush 21 rotates.
  • These toothed belts 27 are not shown in detail connected to the front wheels 4 of the drive of the conveyor belts 2.
  • an intake duct 29 is provided in the housing 1, the first part of which is shown in more detail in FIGS. 4 and 5.
  • the suction channel 29 opens out via suction openings 31 in a base plate 30 of the basic housing 1.
  • suction openings 31 are shown. This is only meant to be an example.
  • Oblique channels 32 lead from the suction openings 31 to a central chamber 33 (see FIG. 1). These channels 32 run at an angle to the longitudinal axis A of the basic housing 1, as a result of which the intake flow is significantly improved.
  • the intake flow itself is indicated by arrows.
  • a connecting piece 34 leads into a filter space 35, which extends almost over the entire basic housing.
  • the reference number 35 ′ indicates that this filter space 35 also continues from the front and also on both sides of the connecting piece 34.
  • a filter mat 37 lies on the base housing 1 in the filter chamber 35, a part 37 'of the filter mat 37 also being located in the filter chamber part 35'.
  • the filter mat 37 is supported on wedge channels 39, in which the filtered liquid can be removed laterally from the filter chamber 35.
  • the V-grooves 39 can of course also run parallel to the longitudinal axis A.
  • the liquid to be filtered is sucked through the suction openings 31 and the channels 32 into the central chamber 33 and pressed into the filter chamber 35 via a pump, which is preferably designed as a vortex wheel pump 40 and is coupled to the drive 9 or a corresponding gear part of the drive 9.
  • a pump which is preferably designed as a vortex wheel pump 40 and is coupled to the drive 9 or a corresponding gear part of the drive 9.
  • the pump drive which is desirable, is non-positively connected to the device drive 9, the pump must be able to deliver in both directions of rotation (forward or backward travel). In addition, it should be able to convey the resulting contaminants into the downstream filter space 35 without prefilters. This option is provided by a vortex pump 40 with a concentrically arranged ring housing.
  • the filter chamber 35 is otherwise covered by a housing cover 41, this housing cover 41 being connected to the basic housing 1 via hinges 42. Because the filter space 35 is integrated into the cleaning device R itself, the external dimensions of the cleaning device R can be kept extremely small, which has advantageous effects on the flow resistance of the cleaning device and the aesthetic design. It is essential that the plastic used has sufficient dimensional stability.
  • the filter mat 37 used is clamped between the hinged housing cover 41 in a fold, not shown. If necessary. For this purpose, a separate, hinged filter cover can be provided.
  • the liquid flows through the connecting piece 34 and its opening, which is congruent with the filter mat 37, into the filter space 35.
  • the filtered water emerges on the underside of the filter mat 37, the wedge channels 39 ensuring a large-area drainage of the filtered water.
  • the outflow conditions are defined such that uniform outflow conditions occur over the entire filter mat 37.
  • the wedge channels 39 can also be formed, for example, by a corresponding support body, such as a perforated sheet. Furthermore, an outflow is possible as a variant, either directly or via calibrated holes on the underside of the device.
  • housing covers 58 can also be seen on both sides, which in particular protect the drive 9 or the travel belts 2. Furthermore, a transverse brush 59 is provided in the direction of travel after the suction openings 31, which together with the cleaning brush 21 forms a suction space 60. Together with the geometrical configuration of the channels 32, a high cross flow from both sides to the suction openings 31 takes place in the suction space 60. The flow effect thereby achieved optimally sucks off the contaminants loosened by the cleaning brush 21 as well as the sludge and sand deposited in joints.
