Definitions

  • the present invention relates to a set of water flow with multiplication of flow for swimming pool, in particular for a fixed or mobile pool filtration and maintenance group, a pool cleaning and maintenance broom and even a pool cleaning robot.
  • the invention essentially implements, for a multiplication of flow, a system in which an ejector projects a stream of water in a convergent.

  • the rate multiplication factor obtained is relatively small, and never exceeds 2.5.
  • US-4,826,591 also discloses a swimming pool filtration system, shown in Figure 2 which reproduces a figure of this document, in which a pump circulates a stream of water from the pool into a filter. Before returning to the pool, the water passes through an ejector placed in front of a convergent so that water that has circulated in a basket connected to a "skimmer" is sucked by the convergent.
  • the rate obtained by multiplication is not used for circulation in a filter, but only in a debris trap basket such as leaves.
  • the ejector and the convergent are placed near a lower surface of a space at the top of which is housed the basket.
  • US-5,785,846 also discloses an installation, shown in Figure 3 which reproduces a figure of this document, wherein a pump feeds an ejector which projects a stream of water to a pipe aligned in front of it and disposed in a chamber defining a convergent rounded at the entrance of the conduit.
  • the suction effect created by the ejector in the convergent is used for the suction of water which has circulated in a filter and which reaches via a duct opening laterally into the chamber surrounding the ejector.
  • the flow of water from the filter arrives from one side of the ejector and must undergo a change of direction of 90 ° to be driven to the outlet duct.
  • WO 02/086259 discloses a flow-rate water circulation assembly, a portion of which is shown in Figure 4 which reproduces a figure of this document, which gives a multiplication factor greater than 2.5, and which may even exceed 3.
  • This flow multiplication assembly comprises a convergent, a neck and a divergent, and water under pressure is injected in a direction parallel to the inner surface of the neck by a slot disposed at the periphery of the neck.
  • This system is limited to the injection of water into the neck and, given the long length of the slot formed around the neck, this slot must be of very small width; it is found in practice that it is easily stifled, if proper precautions are not taken so that it does not close.

  • the duct 116 connected to the convergent 114 had a length equal to 40% of the length of the convergent 114.
  • the duct portion 16 had been doubled and extended by a divergent, so that the duct 118 had a length equal to 1.75 times that of the convergent 114.
  • the duct 118 of Figure 6B had been extended by a cylindrical duct of length equal to 1.25 times the length of the convergent, so that the conduit 120 had a total length equal to 3 times that of the convergent 114.

  • the body comprises a suction device, having a pressurized water inlet and a vertical duct, sometimes in the form of venturi, in which pressurized water is introduced so that it causes the circulation of an updraft. water from the pool to the filter that is attached to the top of the duct.
  • Such a robot further comprises a cleaning accessory formed of a flexible tube provided with bodies intended to rub against the bottom of the pool to detach the contaminating materials.
  • the pool installations create, for the supply of pressurized water from a robot or a cleaning broom, and sometimes other accessories, a stream of water of moderate power (from the order of 3 to 0.5 m 3 / h at a pressure of 1 to 5 bar, usually 2 to 3 bar, the flow of the same pump decreasing when its pressure increases).
  • a broom has all this power, of the order of 100 W, for the only suction function.
  • a robot has this same power, but in a robot this water flow is distributed in substantially equal amounts between the propulsion functions of the robot, creating an updraft in the vertical conduit, and driving the cleaning accessory. It is thus conceivable that the function of creating an updraft does not have a great power. For this reason, cleaning a pool requires many hours of operation of the robot, so it is often done at night. Since the robot's water supply requires the operation of at least one pump, a noise problem can arise. Above all, this low power available for the updraft does not give enough speed to detach the contaminating material that clings firmly to the pool, so the cleaning accessory is needed.
  • known brooms do not have good stability. In order not to tire the operator unduly, their body must be relatively light. As soon as the filter, which is in the high position, begins to fill with sheets, they tend to tilt and tilt the filter on one side. Even if the weight of the materials collected is small, the filter tends to tilt the broom on the side to which the bag is deported. If this tendency to tilt is oriented in the axis of the telescopic handle of the broom, it is sufficient for the operator a moderate effort to compensate for the effect observed. However, if the bag tends to tilt laterally relative to the axis of the handle, the operator must exert on the handle torsion forces increasingly important, and undergoes significant fatigue. Some telescopic handles also do not allow the application of such a torque, so that the broom must be out of the pool very frequently for emptying the bag.
  • a broom has a high power, high mobility and high stability.
  • the high power is achieved through several features which are firstly the high flow multiplication factor obtained through the water circulation assembly according to the invention, secondly the large extent over which a rapid flow of water flows on the the bottom of the pool, this rapid flow of water being obtained by the formation of a thin layer of liquid in the guide space at the lower surface of the brush, and thirdly the formation of a peripheral skirt which delimits the zone of action of the powerful current formed.
  • the high mobility is achieved by using wheels arranged so that they avoid direct contact of the body with the bottom of the pool on a convexity.
  • the high stability is obtained by lowering the center of gravity of the broom due to the accumulation of contaminant collected at a low location of the blade, either directly on the base of the body or near the lower part of the blade.

As this space has a low height, the water flows with great speed and therefore has a significant cleaning effect. This effect is further reinforced at the edges of the broom since the skirt delimits a locally very small space and therefore causes an acceleration of the water which then takes a high kinetic energy on the bottom of the pool.
  • the wheels 218 are mounted on ball bearings, preferably stainless, and as they are arranged on two lines (oriented parallel to the direction of the telescopic handle attached to the rod 240 of the endpiece 238), the base does not come directly in contact with a convexity, because the wheels in the middle of each line come in contact with convexities and allow easy movement.
