Description

The present invention relates to the cleaning of

  the water of a basin in particular of a swimming pool.

  Most of the basins and almost all of the existing pools have a water purification circuit which includes suction means arranged in the vicinity of the water surface for the suction of the surface layer. These skimming devices are

  referred to as "skimmer" in the art.

  In addition, in most swimming pools, vacuum cleaners are provided and better still brushes which, on the one hand, rub the bottom and the walls and, on the other hand

  hand, suck off the unstuck waste.

  Some brushes are automatic and must therefore be connected to the suction circuit of the water circulation pump

  of the swimming pool, suction circuit which ensures the epu-

  ration by passing water through filters and others

processing organs.

  The purification circuit of a swimming pool comprises, as explained below, a set of relatively complex conduits provided with valves which are

found in a technical room.

  It appeared difficult to install, on an existing installation, a broom with automatic functioning by suction of water or even a simple suction nozzle of the bottom of the swimming pool while leaving

operate the skimmer.

  To ensure roughly correct operation

  rect, it is necessary, until now, to regulate, on several occasions, the valves being in the technical room, which requires the frequent presence of two people, one in the technical room, the other at the edge

  of the basin to ensure proper functioning.

  The invention solves the problem described.

  According to the invention, the flow regulation device for a circuit for cleaning a pool, in particular a swimming pool comprising at least one skimming device and at least one vacuum cleaner

  to be connected to a circulation pump is charac-

  terized in that the vacuum brush is connected by a flexible hose to a tubular body connected, moreover, to the circuit leading to the suction of the pump, the tubular body having at least one submerged lumen, and a sheath being provided around of said body and itself comprising a light which can be brought more or less into

coincidence with that of said body.

  Various other features of the invention

  moreover emerge from the detailed description which

follows.

  An embodiment of the object of the invention

  tion is shown, by way of nonlimiting example,

to the accompanying drawings.

  swimming pool and its purification circuit.

  Fig. 2 is a schematic perspective, part

  in section, of the skimming device comprising the device

  tif flow control of the invention.

  Fig. 3 is a top view of the device of the invention.

  Fig. 4 is a cross-section seen sensi-

  along line IV-IV of fig. 3.

  Fig. 5 is a partial section similar to the

fig. 4 but tour of 90.

  In the drawing, 1 designates a basin, in particular that of a swimming pool, containing a body of water whose level

is designated by 2.

  The basin I comprises at least one skimming device 3 known in the art under the English designation "skimmer", this device comprising a bowl 4 generally formed in the masonry of the basin 1, the bowl 4 being slightly below level 2 of water as well as the lower edge 5 of entry of the skinmmer 3 which

  practically flush with said level 2.

  The skimmer bowl 3 contains a basket 6 (fig. 2) for retaining large floating waste such as wood twigs, leaves, papers, etc. The skimmer bowl 4 is connected by a conduit 7 to a collecting pipe 8 leading to a purification assembly 9 through which the water of the swimming pool is caused to circulate by a pump 10. The purified water is then discharged into the pool basin by a

  manifold 11 leading to distribution conduits 12.

  For the water purification to be correct, at least one conduit 13 connects a bottom outlet 14 to the collecting pipe 8 and a conduit 15, opening close

  of the pool water surface, allows the branch-

  ment of a broom 16 constituting at the same time a vacuum

  for waste that has settled and is on the

  bottom of the pool and / or its side walls.

  The various conduits such as the conduits 7, 13 and 15 above are provided with valves 7a, 13a, 15a which are arranged, as far as possible, in the same room or at least close to one another

to allow their maneuver.

  When the pump 10 is in operation, from -

  the water in the basin 1 is sucked in by the skimmer 3 which purifies the surface water and, consequently,

floating waste.

  The device 9 purifies the water which is discharged through the conduits 12 to create at least one surface current causing the surface water to flow

always towards the skimmer 3.

  In some pools, several skimmers can be provided to prevent dead zones. - Still other swimming pools have a peripheral channel through which surface water flows continuously as is the case above the edge 5

skimmer.

  In this case, the actual skimmer is

  i.e. bowl 4 and basket 6, is at a point

bottom of the peripheral channel.

  When it is necessary to brush the bottom of the pool as well as possibly its side walls, the brush 16 is connected to the conduit I5 by a flexible pipe 16a and, in this case, it becomes necessary to adjust the valves 7a and 15a in order to ensure that appropriate quantities of water are sucked respectively from the skimmer 3 and from the brush 16 mainly when the latter is itself driven by the water circulated from the pump 10. For this, it is possible to act on the valves 7a and 15a, but, according to the invention, to facilitate and improve the adjustment, the device of FIGS. 3 to 5, either on a nozzle 17 which comprises the top of the basket 6, or in a hole which the top of this basket 6 may comprise, or alternatively, said device of FIGS. 3 at the inlet of the duct 15. The device itself comprises a tubular body 18 having, in its wall, a lumen 19, for example of trapezoidal or triangular shape although

  that other forms may also be suitable.

  The tubular body externally supports a sheath 20 also comprising a light 21 which can

  be of the same shape as the lumen 19 of said tubular body

  laire. The sheath 20 forms or is connected to a plate 22 at the periphery of which is defined a skirt 23 whose height is chosen so that it extends to a level below the lowest part of the slots 19 and 21 when the body tubular is held vertically

  in the position illustrated in fig. 4.

  A seal 24 is interposed between the

  tubular body 18 and the sheath 20.

  Preferably, the seal 21 is arranged in a groove 25 of the tubular body 18 for a matter of

ease of manufacture.

  The plate 22 has, on its top, two stops 26 and 27 between which is arranged an index 28

  formed from the tubular body.

  It is advantageous that the stops 26 and 27 present

  tent notches 26a, 27a of shapes and dimensions corresponding to the lateral edges of the index 28 which is thus partly housed in one or the other of said notches when the plate 22 is rotated relative to the tubular body 18 and, by therefore brought into a

  position for which the two lights 19 and 21 coincide

  tooth completely or, on the contrary, in a position

  for which these two lights are completely deca-

related to each other.

  It is advantageous, in addition, that a mark 29, which can be graduated, is formed on the top of the plate 22 so that it is possible to view

  o the coincidence state of lights 19 and 21.

  Given their shapes, both the tubular body 18 and the sleeve 20, its plate 22 and its skirt 23 can easily be made of material.

  molded synthetic, for example in thermoplastic material

  than injection molded. Many known materials

  techniques such as polyamides can

  nir. The tubular body 18 protrudes on either side of the sleeve 20 and it is provided, on its projecting end on the side of the opening of the skirt 23, with a sleeve 30. The sleeve 30 is preferably made in flexible material, for example in neoprene, and advantageously comprises an internal central stop 31 to limit

  its fitting onto the tubular body 18.

  In addition, it is advantageous that, at rest, the base of the sleeve 30 is slightly conical as silhouetted in a; this makes it possible to use the sleeve 30 either to cap a tip or to insert it into the mouthpiece

of a conduit.

  In addition, this embodiment in flexible elastic material makes it possible to compensate for the tolerances and / or dimensions which exist between the different brands.

pool accessories.

  As shown in the drawing, the level 2 of water is normally established along the height of the skirt 23. Furthermore, the lowest part of the lumen 21 being located above the base of the skirt 23, it follows that said skirt prevents any air intake and, thus, any formation of vortices which can be the cause of air intake by formation

of a vortex.

  To mount the device as illustrated in fig. 2, the operator engages the sleeve 30 on the end piece 17 of the basket 6 and then sets up the flexible pipe 16a of the

broom 16.

  By turning the skirt 23 more or less, this-

  causes the sheath 20, which makes it possible to adjust the coincidence state of the lights 21 and 19 and, consequently, the volume of water sucked in for skimming the surface of the basin, possibly favoring suction by the

flexible hose 16a of the brush 16.

  The appropriate adjustment can be made without having to enter the technical room containing the

adjustment valves.

  The invention is not limited to the embodiment shown and described in detail, since various modifications can be made without departing from its scope. In particular, the sleeve 30 can have the

  form a bracket to allow mounting of the device

  tif in the mouth of the conduit 15 can lead

  in the side wall of the pelvis 1.
