Definitions

  • the invention relates to a surface cleaner device immersed in a liquid, in particular a swimming pool.
  • the access hatch to the filtering device is located at the base of the hollow body, the liquid inlets then necessarily being equipped with non-return devices such as valves.
  • non-return devices such as valves.
  • the invention aims to provide a submerged surface cleaner device whose performance ratio / cost is greatly improved over that of prior devices. More particularly, the invention aims to provide such a device whose cost can be substantially lowered, for equivalent performance, or even greater than those of known devices.
  • the invention also aims at providing such an apparatus, the filtering device of which can be easily dismounted without any specific tool and extracted from the filtration chamber without major difficulties.
  • the invention also aims at providing such an apparatus, the filtering device of which can be cleaned in a particularly convenient manner.
  • the invention also aims at providing such an apparatus which has high hydraulic (flow, suction, etc.) and filtering performances.
  • the invention also aims at providing such an apparatus that can have an access hatch located on the top of the apparatus and with a filtering device having a large debris storage volume and a simple hydraulic circuit which induces small losses of charge.
  • An apparatus comprising such a filter device with two shells assembled to one another so that once assembled they form a filter housing in one piece easily extractable from the device, is particularly practical to use.
  • a filter housing has a first shell which serves as a debris recovery bag and a second shell which serves as a liquid inlet conduit and partially obstruct the debris recovery bag so that when the device is operating on a submerged surface, the debris are housed in the debris recovery bag without being able to come out through the liquid inlet.
  • the two shells are adapted to be dissociated from one another, once the filter housing extracted from the device. Therefore, it is particularly convenient to clean the filter device by separating the two shells from each other and removing the debris stuck in the first shell. Once the first shell forming the cleaned debris collection bag, a user can assemble the shells to one another and reinsert the filter housing thus formed in the device.
  • this particular arrangement allows both to maintain high hydraulic performance (flow, suction) and filtering, while improving access to the filtering device and facilitating the cleaning of this filtering device.
  • this filtering device can have a large volume of debris storage without loss of harmful load.
  • the two shells are assembled to one another so as to be dissociated from one another by simple manipulation without tools.
  • the shells are assembled to one another by reversible embedding means.
  • the front opening of the first shell extends around the periphery of a rear wall of the second shell and the inlet opening.
  • the two shells are assembled to one another according to a junction zone which extends generally transversely and orthogonally to the longitudinal direction.
  • the second shell forms at least one liquid inlet duct extending from a lower end of this inlet duct opening at the base of the hollow body and constituting a liquid inlet.
  • the filter housing thus formed comprises a lower end which opens at the base of the hollow body and which constitutes a liquid inlet.
  • this filter housing forms the "dirty" part, called dirty circuit, of the hydraulic circuit of the device, that is to say the part of the hydraulic circuit capable of transporting debris.
  • the filter housing being removable, the dirty circuit is completely removable. A user can therefore clean the entire dirty circuit of the device and thus restore to a device according to the invention its initial performance.
  • the second shell has a rear transverse separation wall extending transversely to the front of the debris recovery volume, between each liquid inlet and said inlet opening provided at an upper end of said duct. input.
  • This transverse rear wall acts as a non-return wall so that debris that has passed this wall can no longer emerge through the liquid inlet, even when the pumping device is stopped, which eliminates the need to spare valves or other non-return devices on the liquid inlets.
  • the inventors have found that the arrangement of this wall on the path of the liquid between each liquid inlet and each liquid outlet, which at first sight may seem unfavorable from the point of view of hydraulic performance (flow, suction,. ..), actually improves filtration performance by generating turbulence at in the filtering device which permanently maintain debris suspended in the filtering device, thus avoiding clogging of the walls of the filtering device, and ultimately promoting the hydrodynamic performance of the filtering device and the hydraulic circuit.
  • the pressure losses induced by the arrangement of a wall on the hydraulic path are compensated by maintaining the initial permeability of the filtering walls of the filtering device.
  • the periods of service between which the device must be cleaned are longer and especially of substantially constant duration, to the benefit of greater comfort of use.
  • the first shell comprises a rigid frame adapted to impose a three-dimensional shape to these peripheral walls, and a filter sheet extending into openings formed by the rigid frame.
  • said first shell has a decreasing transverse cross section from front to rear.
  • a filtering device whose transverse cross section is decreasing from front to rear makes it possible to ensure filtration of the essentially tangential type of the liquid circulating in the filtering device.
  • a convergent shell also causes a swirling of the liquid flowing in this shell, which ensures a continuous unclogging of the walls of the hull having the effect of restoring to the various walls of the hull their initial permeability.
  • said first shell has a horizontal upper wall extending from the front opening, and a lower rear wall inclined rearwardly and upwardly since a bottom portion of the first shell, to an upper rearmost portion.
  • At least one of the shells has a handle for handling the filter housing.
  • Such a handle allows easy handling of the filter housing when the two shells are assembled to one another.
  • said access hatch is formed on an upper wall of the hollow body.
  • Such an apparatus is particularly practical to handle since the extraction of the filtering device from the apparatus does not impose delicate manipulations of the apparatus. In particular, it is not necessary to return the device to remove the filter device for cleaning. Disassembly of the filter device can be achieved while the device is at rest, in its normal position, on a horizontal surface.
  • an apparatus according to the invention is free of a check valve of liquid.
  • an apparatus comprises at least one liquid outlet out of the hollow body, said rear outlet, shifted rearwardly with respect to the filter housing.
