Definitions
- the present invention relates to the cleaning of swimming pools, basins, spas or the like.
- the invention relates to an automatic device for cleaning the bottom and walls of a swimming pool.
- Aspiration must be started by filling the entire circuit with water. As a result, it is necessary to monitor the operation of the vacuum cleaner to verify that it does not defuse, which can happen during its movements.
- the debris is entrained in the pre-filter of the skimmer used and, in part, in the pump 3 and the filter 4.
- the pre-filters and filters are clogged, hence the risk of clogging of the latter, as well as pump cavitation and defusing.
- These vacuum cleaners are therefore not practical or easy to use.
- the device described in this document comprises a housing provided with a suction mouth located a short distance from the surface to be cleaned.
- This device is weighted so suitable so that, throughout its movement, the suction mouth remains as close as possible to the surface to be cleaned. All the water discharged from the pool discharge mouth is available for the operation of the ejector, the jet ensuring both the suction of debris and the movement of the device in the pool. It is simple and inexpensive in design and overcomes the drawbacks of vacuum cleaners that operate on suction.
- this device still has some drawbacks. Indeed, its ballast only allows it to move on the bottom of the pool or on slightly sloping walls. For example, he cannot clean the vertical walls. In addition, it has a low capacity for collecting and storing debris.
- the present invention aims to remedy the drawbacks of the devices described above by proposing a device operating in discharge of simple design, which is reliable, which makes it possible in particular to clean the bottom and the substantially vertical walls of the swimming pool, which does not require for move from continuous sampling of the water supplied to the ejector, so that it can operate automatically while being only connected to a discharge opening in the swimming pool.
- FIG. 2 represents the same swimming pool P equipped with a cleaning device 9 according to the invention.
- the elements common to Figures 1 and 2 have the same references in Figure 2 as in Figure 1.
- the device 9 is connected to the discharge mouth 5 by a flexible pipe 10 of the known type with an accordion wall.
- the pipe 10 is of great length, namely of length at least greater than the largest dimension of the swimming pool.
- the device 9 is shown in detail in Figures 3 to 5. It comprises a suction-discharge body 11 having a suction orifice or mouth 12 and a discharge orifice 13, an ejector disposed in said body 11 and comprising a driving nozzle 14 and a venturi diffuser 15, a rigid duct 16 for supplying the nozzle 14 with pressurized water, a debris receptacle 17, a flexible flange or skirt 18 and a cyclic discharge valve 19.
- the body 11 is formed, in the embodiment shown, by a cylindrical duct with a vertical axis, the wall of which is locally deformed to form the diffuser 15.
- the lower end of the cylindrical duct forms the suction mouth 12 in the vicinity of which is arranged the flange 18.
- the upper end of said conduit forms the discharge orifice 13 to the right of which is mounted the debris receptacle 17.
- a small side suction window 20 is formed on the body 11, in line with the flange 18.
- the conduit 16 is bent and comprises a part 16a with a horizontal axis H perpendicular to the axis of the body 11 and penetrating into the latter and a part 16b with an inclined axis I (FIG. 7).
- the flexible hose 10 is connected by any suitable means to the conduit 16b.
- the nozzle 14 is arranged vertically, coaxially with the body 11 and laterally with the supply duct 16a, and defines a horizontal nozzle.
- the section of the nozzle 14 tapers progressively from the duct 16a to the nozzle which defines a narrow outlet generating a water jet with a vertical axis.
- the section of the duct 16 is for example of the order of half that of the body 11.
- conduit 16 is extended outside the body 11, opposite the part 16b, by a part 16c provided with said cyclic discharge valve 19.
- the dif fuseur 15 has a neck 15a located substantially in line with the nozzle of the nozzle 14.
- the debris receptacle 17 is removable and of openwork structure. It acts as a filter allowing the water coming from the outlet orifice 13 to pass while retaining the entrained debris.
- the cyclic discharge valve 19 is shown in exploded view in FIG. 5.
- the extension 16c of the conduit 16 is cylindrical and has a perforated circular bottom 21, the center of which is provided with an axis 22 carrying a turbine 23.
- the duct 16c comprises two symmetrical openings 24.
- the turbine 23 is formed by a cylindrical sleeve, called the inner sleeve 25, which caps the extension 16c.
- the inside diameter of the sleeve 25 is slightly greater than the outside diameter of the conduit 16c.
- This inner sleeve 25 has a circular bottom 26 provided with a hole 27 for the passage of the axis 22.
- a nut 28 ensures the mounting of the inner sleeve 25 on the axis 22.
- Appropriate means (not shown) are provided for that the inner sleeve 25 is free to rotate about the axis 22.
- the sleeve 25 In the vicinity of its bottom 26, the sleeve 25 comprises two radial conduits 30 each provided at their end with a hole 32 for the reaction drive of the rotating sleeve 25.
- the inner sleeve 25 is mounted so that the radial conduits 30 are located between the bottom 26 of the sleeve interior 25 and the perforated bottom 21 of the conduit 16c ( Figure 3).
- the inner sleeve 25 comprises two symmetrical openings 34 arranged so as to come opposite, during the rotation of the sleeve 25, with the openings 24 of the conduit 16c.
- An outer sleeve 35 remotely envelops the inner sleeve 25 in order to form a deflector whose role will be explained below.
- the sleeve 35 comprises two diametrically opposite notches 36 receiving the radial conduits 30 which thus ensure the rotational drive of said sleeve 35 ( Figure 3).
- the cleaning apparatus 9 according to the invention operates in the following manner.
- One end of the flexible pipe 10 is connected to the conduit 16b.
- the device 9 is placed on the bottom of the pool P and then the other end of the pipe 10 is connected to a discharge mouth 5 of the pool P.
- a small part of the water discharged into the pipe 10 passes through the perforated bottom 21 of the conduit 16c, to be ejected through the holes 32 of the radial conduits 30.
- the sleeves 25, 35 start to rotate.
- the difference between the outside diameter of the sleeve 25 and the inside diameter of the sleeve 35 is such that the water coming from the openings 24, 34 can be quickly evacuated between these two sleeves, in a direction which does not disturb the movement of the device.
- the difference between the outside diameter of the pipe 16c and the inside diameter of the sleeve 25 is such that the water leaks between these two elements are minimal.
- the depression created in the vicinity of the suction mouth 12 and the flange 18 allows the device to be pressed as well at the bottom of the pool as on its walls, even substantially vertical.
- the apparatus described is inexpensive and adapts to all types of swimming pools. It limits the disturbances in the functioning of the skimmers 2 and of the bottom drain 1, which continue to ensure their function during the use of the device.
- the debris receptacle 17 makes it possible not to further foul the pre-filters and filters 4 of the circuit of the pool, reducing the risk of cavitation of the pump 3.
- the device 9 described above accepts many variants, including those of FIGS. 6 to 11.
- FIG. 6 a variant has been illustrated in which the debris receptacle 17 is replaced by a removable filter cartridge with an opaque wall 37.
- This cartridge 37 makes the device more aesthetic, since the debris remains hidden inside the cartridge.
- the pipe 16b has been provided with an external sleeve 38 driven in rotation by means of a turbine 39 supplied with part of the water circulating in the pipe 16b.
- This turbine drives the sleeve 38 by a pinion 40 and belt 41 system.
- a speed reducer, symbolically represented at 50, is disposed between the turbine 39 and the pinion 40.
- the sleeve 38 comprises an exhaust duct 43 with an axis perpendicular to the axis I and an exhaust duct 44 bent in the direction of the device 9.
- the rotation of the sleeve 38 around the duct 16b allows the exhaust ducts 43 and 44 to communicate alternately with said duct 16b via an orifice 45.
- the role of the exhaust pipes 43, 44 is to generate a lateral offset of the pipe 16b with a component parallel to the axis I, the effects of which add to those of the constriction and the stretching of the pipe 10.
- the device described with reference to FIG. 7 can replace or supplement the relief valve 19.
- FIG. 8 schematically represents a variant of the apparatus of the invention, in which the bent part of the conduit 16 is articulated at 46, around an axis substantially perpendicular to the plane defined by the axis of the body 11 and the axis H of conduit 16a. This facilitates the passage of the device 9 from the bottom to the walls of the pool.
- FIG. 9 schematically represents part of a fourth variant of the apparatus of the invention, in which the cyclic discharge valve is provided, not on an extension of the pipe 16a outside the body 11 or on the pipe 16b, but on a connection piece from the pipe 10 to the discharge mouth 5.
- the connection piece similar to the device shown in FIG. 7, is symbolized at 47.
- the inclined portion 16b of the conduit 16 can be removed and the pipe 10 directly connected to the portion 16a.
- Figures 10 and 11 illustrate an improvement of the apparatus of the invention intended to peel it from the wall of the swimming pool when it arrives on the water line.
- the apparatus is provided with a flexible tube 48 opening into the body 11, preferably below the venturi diffuser and provided at its free end with a float 49.
- the tube 48 When the apparatus arrives at the water line (FIG. 11), the tube 48 temporarily introduces air into the body 11 and the filter 37, which causes the apparatus to tilt according to arrow 50.
- the apparatus straightens up, thus peeling off automatically from the vertical wall 51 of the swimming pool, then plunges towards the bottom while purging the air which has been introduced by the tube 48.
- Such a device improves the efficiency of the device by reducing the time spent on the walls of the pool.
- the invention is not limited to the embodiments shown and described, but on the contrary covers all variants thereof, in particular with regard to the structure and the location at any location between the nozzle 14 and the mouth.
- discharge 5 of the discharge valve 19 It should be noted that the discharge mouth can be replaced by other devices supplying water under pressure, such as a booster.
