Definitions

  • This invention relates to a flow regulation device for the cleaning system of a pool and, more particularly, of a swimming pool.
  • the mobile cleaning devices are powered by a water stream drawn through the units by vacuum.
  • the vacuum is applied to the mobile cleaning device through a flexible hose which is typically connected to the water filtration system through an aperture in the skimmer plate.
  • the arrangement is such that, until relatively recent times, if the mobile cleaning device was connected to the skimmer plate, the skimmer unit itself could not function.
  • the invention consists in a flow regulation device for mounting between a swimming pool skimmer unit and a vacuum operated mobile underwater swimming pool cleaner, said device including a substantially cylindrical flow conduit having a first end communicable with a source of vacuum applied at the skimmer and a second end communicable with a mobile swimming pool cleaner, said flow conduit having an aperture in the wall thereof ; and a valve means having a substantially cylindrical valve surface slidable over that part of the flow conduit including said aperture, said cylindrical valve surface having an aperture therein adjustably alignable with the aperture in said flow conduit, and a peripheral skirt extending from, and about, said cylindrical valve surface to define a void in communication with the aperture in said cylindrical valve surface, the entrance to said void being in a plane located closer to said first end of said flow conduit than that part of the aperture in said cylindrical valve surface located closest to said first end.
  • the flow device is preferably located substantially vertically on a skimmer plate incorporated in the swimming pool skimmer unit. Accordingly the first end of the flow conduit is the lower end while the second end is the upper end. When in position the skirt incorporated in the valve member extends below the lowest boundary of the aperture in the cylindrical valve member.
  • the skirt preferably extends vertically downward from an annular ring extending about the upper edge of the valve member and thus a substantially annular void is defined which is sealed at the upper end.
  • Suitable projections may be provided on the annular ring which co-operate with an abutment extending from the outer wall of the flow conduit to define two limit positions of the valve member with respect to the flow conduit. These limit positions, in turn, indicate when the apertures are perfectly aligned with one another and when the aperture in the flow conduit is completely covered by the valve member.
  • a swimming pool 1 is depicted containing a body of water whose level is indicated by reference numeral 2.
  • the pool 1 includes at least one skimming device 3 which will be referred to hereinafter by its typical name "skimmer".
  • the skimmer includes a weir 4 in the front thereof.
  • the weir 4 may be formed by part of the wall surface of the pool 1 and is located slightly below the water level 2 so that the surface water in the pool may be drawn toward the skimmer 3 by vacuum applied at the skimmer.
  • a pipe 7 leads downwardly from the skimmer 3 and connects with drainage piping 8 through a valve 7a. With the valve 7a open, water can be drawn from the skimmer 3 through pipe works 7 and 8 and through filtration unit 9 by pump 10. The filtered water is subsequently pumped back to the pool through delivery pipe 11 and distribution pipes 12. Water may also be drawn through bottom intake 14 which is connected to the inlet side of the filtration unit through connecting pipe 13 and valve 13a.
  • a mobile cleaner 16 is generally provided which, in the form shown, is connected to a vacuum aperture located in a convenient location and provided on the distal end of pipe 15 which is connected into the drainage pipe 8 via valve 15a.
  • the cleaner 16 is connected to the pipe 15 by a flexible pipe 16a which permits the cleaner 16 to move over the floor and walls of the pool 1 beneath the surface 2.
  • the form of pool cleaner is not part of the invention and may comprise any of the forms of vacuum operated swimming pool cleaner. Some examples include those sold with reference to the trade marks QUESTA 2000, POOL VAC and KREEPY KRAULY.
  • the pool cleaner 16 When it is desired to clean the floor and walls of the pool 1 the pool cleaner 16 may be connected to vacuum pipe 15 by a flexible hose 16a. In this event it is necessary to adjust valves 7a and 15a so that the appropriate vacuum is applied to the cleaner 16. In some instances it is possible to effect the appropriate adjustments through valves 7a and 15a but, in those instances, it is still necessary to use considerable manual effort, adjusting the various valves, in order to achieve the optimum speed for the pool cleaner.
  • a flow regulation device is provided which is fitted to the skimmer 3 between the skimmer 3 and the flexible pipe 16a connected to the mobile cleaner 16.
  • the device which is shown in Figs. 3 to 5, permits the skimmer 3 and mobile cleaner to operate simultaneously and also permits the relative amounts of vacuum applied to each to be simply adjusted. This, in turn, enables the speed of the pool cleaner to be adjusted.
  • Fig. 2 the flow regulation device according to the invention is fitted to an aperture 17 commonly provided in the skimmer plate 6a which, in typical skimmers, covers skimmer basket 6.
  • the skimmer basket 6 collects debris drawn in through the skimmer.
  • the vacuum source which operates the skimmer is applied through pipe 7 which, as can be seen, is located beneath the skimmer basket 6.
  • the flow regulation device comprises a cylindrical flow conduit 18 having a port or aperture 19 in the wall thereof.
  • the particular shape and size of the port 19 is not essential to the invention but, in the form shown, the aperture 19 is trapezoidal in shape.
  • the flow regulation device further includes a valve member which is slidable with respect to the flow conduit 18, the valve member having a cylindrical valve surface 20 which includes a port 21 in the wall thereof, the port 21 preferably being of the same shape as the port or aperture 19 in the flow conduit.
  • a skirt 2.3 Extending from and about the cylindrical valve surface is a skirt 2.3.
  • the skirt 23 is configured and arranged to overlie, but be spaced from, the aperture 21 and defines a void about the aperture so that when the device is in position the skirt 23 extends below the lower boundary of the aperture 21.
  • the skirt 23 preferably projects vertically downward from an annular plate 22 extending outwardly from the upper edge of the cylindrical valve surface 20.
  • flow regulation device herein described preferably provides for rotational sliding movement between the flow conduit 18 and the valve member.
  • suitable stop means are preferably provided to limit the relative rotational movement between the valve member and the flow conduit between a first limit-position in which the apertures or ports 19 and 21 are fully aligned and a second limit-position in which the aperture 19 is fully covered by the cylindrical valve surface 20.
  • a pair of projections 26 and 27 are included on the annular plate 22 forming part of the valve member. These projections 26 and 27 co-operate with an abutment 28 projecting from the outer wall of the flow conduit 18.
  • the plate section 22 preferably includes visual markings thereon to indicate the positions of the valve member with respect to the flow conduit.
  • suitable sealing means is preferably provided between the valve member and the flow conduit.
  • the sealing means comprises a rubber O-ring 24 located in peripheral groove 25 provided around the outer wall of the flow conduit above the aperture or port 19.
  • a bush 30 is preferably provided on the lower end of the flow conduit to allow a sealing fit between the flow conduit and the skimmer plate 6a.
  • the bush 30 is preferably made from a flexible material such as, for example, neoprene and may include an internal stop 31 to limit the extent of its fit on the flow conduit 18.
  • the bush 30 is preferably formed with a slightly conical lower end 30a. This allows the bush 30 to be used as an external cover for a nozzle or, alternatively as an internal fit in a cylindrical opening.
  • the flow regulation device as herein described is fitted substantially vertically to the skimmer plate 6a of a swimming pool skimmer by inserting end 30a of the bush fitted to the lower end of the device into the aperture 17 in the skimmer plate 6a.
  • end 30a of the bush fitted to the lower end of the device into the aperture 17 in the skimmer plate 6a.
  • the lower end of skirt 23 is submerged beneath the surface 2 of the water within the pool as can be seen from Fig. 4.
  • the skirt prevents any suction of air upon operation of the pump 10.
  • the flexible hose 16a attached to the mobile cleaner 16 may then be fitted to the upper end of the flow conduit 18 and power applied to the pump 10. The operator may then rotate the valve member between the limits imposed by the projections 26 and 27 to adjust the water flow through the mobile cleaner 16 and thus the speed of operation thereof.
  • bypass valve which not only permits the water flow through a mobile cleaner to be simply adjusted but also permits the mobile cleaner to operate simultaneously with the pool surface skimmer.
