Definitions

  • the invention relates to an independently moving machine according to the preamble of claim 1.
  • the cleanest type of cleaning can be achieved with water suction, since all, in some cases slimy, sediments are conveyed through the suction hose directly to the filter system of the circulation pump, from where they reach the sewage system through the backwashing process.
  • a machine operating according to this operating mode is explained, for example, in CH-A-584 828 and is specified in CH-A-648 893 by a modified form. These designs work flawlessly in swimming pools of any shape, assuming a flat floor with only a limited gradient.
  • the above-mentioned devices are unusable for American-style swimming pools with often flowing transitions between the floor and the wall as well as spring pit recesses.
  • a machine tailored to this basin shape US-A-4 156 948 can hold onto any steep walls with a suction plate and is moved towards the suction plate by strong knocking. This device has only a very limited possibility for locomotion and directional control and gets stuck everywhere.
  • an automatic swimming pool cleaner is described according to the preamble of claim 1, which has three suction plates. Two of these suction plates are freely tiltable and rotatable at the bent ends of a suction nozzle.
  • the third suction plate is arranged at the end of a hollow piston rod which is attached to a piston.
  • the piston can be displaced into a cylinder rigidly connected to the intake port.
  • a suction pipe that can be connected to the suction side of a pump is connected either to two suction plates on the suction nozzle or to suction plates attached to the piston rod.
  • this cleaner is carried out by moving the suction plate attached to the piston rod in a straight line with respect to the other two suction plates and by straightening the two other suction plates mentioned. Accordingly, the cleaner only moves in a straight line on the horizontal surface and therefore often gets stuck in the corners of the swimming pool.
  • FIG. 1 A water turbine, not shown, drives an intermediate gear and reduction gear 6 via its turbine gear 11 and a gear 4, which engages with a plate drive gear 8 and sets a suction plate 2 in slow continuous rotary motion with the axis of rotation B via a centrally located suction nozzle 10.
  • a suction plate 1 is rotated via gears 3, 5, 7 and suction nozzle 9.
  • the directions of rotation are indicated by arrows.
  • Both suction plates 1 and 2 made of elastic material, for. As silicone rubber, rotate in the opposite direction of rotation and slide over the pool floor.
  • the existing swimming pool filter systems work with different amounts of water and suction power in the machine can be reduced to acceptable, uniform operating values by valve control.
  • a suction pressure of 20 mbar is sufficient to achieve a suction plate contact pressure of approx. 200 N.
  • the machine can thus safely move to the water surface of a swimming pool lined with plastic sheeting without loosening the sheeting by suction from the outer wall.
  • FIG. 2 A possible suction plate control is explained using a sectional drawing according to FIG. 2.
  • An elongated housing 53 has two filter chambers 14 and 15 and a turbine chamber 24 arranged between them.
  • the suction plates 1 and 2 are rotatably mounted in the bottom of the housing 53.
  • the suction line of the filter system is attached to a rising pipe 13 of the machine, which can be rotated axially relative to the housing 53, via a flexible suction hose (not shown).
  • the entire water flow now flows through the inner tube of the suction nozzle 10 provided with a non-return flap 16 into the filter chamber 14, then through a filter screen 18 and an open valve flap 20 into the turbine chamber 24 and through a water turbine 25 to the riser pipe 13.
  • the water turbine 25 runs and drives via a drive shaft 26 and the turbine gear 11, the reduction gear 5 and 6 and the suction plates 1 and 2, as described above.
  • the plate drive gear 7 rigidly connected to the suction nozzle 9 additionally controls a driver lever 23 via an eccentric disk, not shown, which brings the two valve flaps 20 and 21 into their opposite switching positions via a switching rod 22.
  • the water flow will proceed analogously through the suction port 9 released by a non-return flap 17 and a filter screen 19, the open valve flap 21, the turbine chamber 24 and the water turbine 25 to the riser pipe 13.
  • the suction plate 2 will, for example, suck itself onto the floor and interrupt the water supply; the suction force increases to approx. 5000 N.
  • Remedial measures are taken by installing a compensating valve arrangement, whereby the open valve passage should be larger than double the inner inlet port.
  • the water coming from the outside flows in the direction of the arrow (FIG. 2) through an outflow valve 27 into a valve chamber 32 within a valve box 52, then through an outflow valve 28 into a valve channel 33 and an opening 54 in the outer tube 73 of the suction nozzle 10 under the suction plate 2.
  • the water is diverted through the basin floor at a high flow rate under the suction port 10, whereby a great cleaning effect is achieved.
  • a spring 35 of the compensating valve 29 is responsible for the forces under the suction plate 1.
  • a roller chain 39 (FIG. 2), which is anchored rotatably on the two suction support zones 9 and 10, interrupts the bottom fit of the two suction plates 1 and 2 at one point. There is a local water flow through which larger sediments, such as. B. leaves are transported under the suction plate.
  • the suction plates 1 and 2 are identical and have radial water passage channels 40 (FIGS. 2 and 5) from the center, which open into a concentric compensating bead 38. Further out there is a sealing flange 37 with an edge 42 bent upwards. If the machine moves over the basin floor and reaches an upright wall at an angle of, for example, 45 ° (FIG. 3), the edge 42 ( Fig. 2) bent over with the sealing flange 37 over the compensating bead 38, whereby water can flow in. The fixed suction pressure under the suction plate 2 coincides and the suction plate 1 is no longer moved forward.
  • the suction plate 1 sucks and presses the suction plate 2 even more firmly against the wall.
  • These processes are repeated alternately until the suction plate 2 has pushed through the wall and the machine is again moved in direction D (Fig. 3).
  • the machine moves vertically in the direction of arrow E towards a wall, the edges 42 on both suction plates 1 and 2 are pushed up and the suction plates lose their great grip, which has a gentle effect on the mechanics. Relief from this operating situation is achieved via a programmed forced release, which is designed in such a way that a shaft drive, which will be explained later and which is connected downstream of the turbine, reverses the directions of rotation of all gearwheels. The machine therefore moves backwards.
  • valve flap 20 (FIG. 2) is open for the suction plate 2.
  • the suction plate 1 rotates around the suction plate 2 in the direction of the arrow.
  • the angle of rotation swept during this time is decisive for the direction that the machine takes when switching back to forward running.
  • the preprogrammed return times alternately result in different directions of travel (Fi, F 2 , F 3 ) from the wall (FIG. 4).
  • the machine will return to the wall with a return angle between 0 to 45 °, with a return angle between 45 and 90 ° deflect in direction D (Fig. 3) and with a return angle between Move 90 and 180 ° in the directions F 1 to F 3 , with a return angle of more than 180 ° always moving away from the wall at right angles in the direction F 2 .
  • the process discussed can take place in the opposite direction by rotating the suction plate 2 around the suction plate 1.
  • the bottom of the suction plate, supported by the compensating bead 38 (FIGS. 2 and 5) and prestressing springs 41, is maintained, which means that the machine over the radius on a side wall of the swimming pool and climbs on it.
  • the reversal is initiated via a buoyancy body 44 or 45 (FIG. 5), as a result of which the machine changes the direction of travel in the manner described above.
  • the return angle is limited to a maximum of 100 ° so that the freely rotating suction plate does not move beyond the water surface, which would suck in air.
  • a slide 46 is pressed to the right by an expansion spring 47 and presses a rocker switch 60 to the left, so that the switching gear 3 is in engagement with the reduction gear 5.
  • the corresponding directions of rotation are indicated by arrows.
  • a release pawl 58 is pulled up by one of the buoyancy bodies 44 and 45 and tensions a spring 61. If the buoyancy is lost or the release pawl 58 is pulled down by a positive release lever 55 via a pin 51 of a cam wheel 56 via a reduction gear 57 a drive pin 59 from the disk drive gear 8 is in contact with the release pawl 58 and press the slide 46 connected via a bearing 62 to the left until the spreading spring 47 with the slide 46 and the rocker switch 60 jumps into the upturned switching position (see FIG. 7).
  • the shaft gear 3 Due to the large power transmission from the water turbine to the suction plate, the shaft gear 3 has the tendency to remain in engagement between the turbine gear 11 and reduction gear 5.
  • the flipped slider 46 abuts with a cam 49 on a pawl 50, which releases a pulling lever 63 via a pivot point 65, which hangs on a bolt 66 of the plate drive gear 7 and thus pulls the switching gear 3 out of engagement against its own holding force.
  • the rocker switch 60 can then switch unhindered to the position shown in FIG. 7.
  • the situation is exactly the opposite for the transmission of power, after which the shaft gear 4 presses itself out of the tooth engagement. Remedy is created via a pawl 64, which prevents the rocker switch 60 from pivoting out.
  • the bolts 69 and 70 from the program gear 67 are unequal in height and the return lever 68 can be moved in height by means of a gravity rocker 71, which means that in the horizontal operating position only the longer bolt 70 triggers the reset, as a result of which the larger return angle of z . B. 200 ° is turned on.
  • both bolts 69 and 70 can trigger the reset, and the ⁇ aximal return angle is only half as large, eg 100 °.
  • the turbine chamber 24 can additionally be provided with a window 75 'which can be closed by a flap 75, see FIGS. 5 and 7.
  • a pressure lever 76 Adjacent to the plate drive gear 8 is a pressure lever 76 which is displaceable in its longitudinal direction and can be pivoted to a limited extent.
  • One end of the pressure lever 76 rests on the inside of the flap 75, which is kept closed by a spring 82, as long as the pressure lever 76 does not act on the flap 75.
  • the other end region of the pressure lever 76 is connected to the release pawl 58 via a pulling element 77 and is pivoted clockwise in relation to FIG. 7 by buoyancy, which acts on the buoyancy body 44, so that the upper end of the pressure lever 76 is disengaged from the Driving pin 59 of the plate drive gear 8 is.
  • the pressure lever 76 is pivoted counterclockwise by a tension spring 79 and is in contact with a pin 80. Now the upper end of the pressure lever 76 is in the path of movement of the driving pin 59. If the plate drive gear 8 rotates clockwise, the driving pin 59 will push the pressure lever 76 downward, whereby the flap 75 opens. In the lower position, the pressure lever 76 is held by a cam which engages behind a stop pin 78. As soon as buoyancy acts again on the buoyancy body 44, the pressure lever 76 is brought back into its rest position. This causes the flap 75 to be closed again and the cleaning device to move forward as described above.
