Definitions
- the present utility model refers to devices used in pool cleaning systems, specially adapted to remove sediments and debris accumulated at the bottom of reservoirs and pools.
- Maj-ntaining the proper conditions to use of pools comprises a group of processes that intend to (1) keep the water's chemical characteristics within predefined parameters; (2) avoid proliferation of microorganisrns and algae; (3) guarantee the water's transparency by removing suspended matter and (4) rnaintain the bottom free of sediments and debris deposited there by decantation.
- to remove decanted material hand bottom vacuum cleaners are used. However, this process must be carried out frequently and requires specialized labour, increasing the costs of operating pools.
- Patent US 5,251,343 describes a bottom's cleaning head equipped with a mobile piston, into which the water enters in a vertical ascendant direction, ejected by horizontal exit in the radial direction provided at the upper portion of said piston.
- the water pressure against its lower surface provides the rising of the latter above the pool's floor, its return is provided by a spring.
- This system requires means to allow the change of the jet's direction, in order to sweep the 360° of the bottom's area that surrounds the head.
- such means comprise a pair of opposite guide pins, moving jointly with ' the piston, on two cylindrical opposite trapezoidal groove courses.
- the piston rises and retracts, which makes the pins advance to the next groove, resulting in a turn whose angle depends on the characteristics of the above mentioned grooves.
- This turn allows the jet's angular movement, resulting in the sweeping of the entire area surrounding the head.
- the system described has some practical inconveniences, due to the complexity of the mechanism used to obtain the above mentioned angular movement, which results in a high production cost.
- the guide pins necessarily thin because of the nature of the system, have their useful life limited due to wear by Motion.
- a first objective is to provide a bottom's cleaning system, comprising one or more devices that produce jets of water adjacent to the bottom with sufficient intensity to move the debris decanted there, placing them in suspension in a liquid means and allowing their removal by suction through the drain at the bottom.
- Another objective is to provide devices in which he direction of the water jet by modified by random phases in order to cover the entire surrounding area.
- Another objective is to structurally provide simple devices simples that do not require sophisticated techniques and costly.
- the objectives above are attained by providing a piston that moves between to end positions, a lower resting one and an upper operating one, said movement is caused by the water pressure and the return to the resting position is provided by the piston's force- weight, the turning movement is only caused by the reaction of a water jet eccentrically directed in relation to said piston's axel.
- the water inlet and outlet channels are rectilinear.
- the piston's turrting occurs during the phase in which the piston is travelling between said end positions.
- the interruption of the water supply to each head occurs gradually to avoid the ram stroke.
- Figures 1 and 2 show a known device, object of US 4,212,088.
- Fig. 3 shows, by means of a cross cut view, the utility model proposed, in its preferred embodiment format.
- Fig. 4 details two aspects of the piston's body.
- Fig. 5 shows, by means of a cross cut view, the operation of the utility model.
- the utility model proposed comprises a body made up by a PVC "T" coupling 11, which side part 12 connects to the piping 13 that links up to the system (not shown), which supplies water under pressure.
- the "T" upper edge fits into a first flange 14 that bears against the metal, vinyl or fibreglass reservoir's or pool's bottom outside face 15 (lower).
- a second flange 17 On the opposite side of said flange and bearing against the bottom's upper face 16, is a second flange 17, which overlaps l ⁇ iird flange 18; the set being attached by stainless steel screws (not clearly shown in the figure).
- piston 21 has a substantially cylindrical shape with discoidal broaden ngs 22, 23 at both ends.
- This assembly allows the piston's perfect alignment at all its positions, making it possible to vertically slide with no leaps.
- the sealing against leaks at the lower mouth of the said "T” is provided by means of a plug 33 attached with adhesive.
- a force 42 is generated, from bottom to top, which is applied on the piston's lower face 21, starting its upward movement from its initial resting position.
- Fig. 5-b shows the piston in the operational position, i.e., at the end of its upward vertical course. In this situation, the lower discoidal broadening edge 23 bears against the ring collar's lower face 24.
- reaction force tangential component of this jet 43' produces a rotational momentum that results in the piton turning some degrees around its axle, so, when said head is activated again, the jet will have a new direction.
- the successive turning angles resulting from the above mentioned effect are random, but after a plurality of operation cycles, around 20 cycles, all the 360° surrounding the device will have been swept.
- a plurality of heads of the type described will be used, distributed in a manner that their jets clean the bottom's total area.
- said devices are activated one at a time by means of an assembly of solenoid valves, which operation is controlled by a set of cams assembled on a rotating axle, according to known control processes.
