Definitions

  • the present invention relates to a washing machine with horizontal drum in a turbulent washing bath.
  • the washing drum In a known washing machine with horizontal drum, the washing drum generally comprises a cylindrical interior surface provided with one or more spaced longitudinal ribs attached or formed in situ by folding or drawing which allow a rotation of this drum, to lift the laundry and to let it fall under the effect of its weight to achieve in this laundry both a stirring and a mechanical washing action, and an outer surface is cylindrical and relatively smooth or is provided with longitudinal recesses formed by outer faces of these interior longitudinal ribs.
  • the washing machine tank contains a detergent bath formed by a predetermined quantity of water and a dose of detergent.
  • the lower part of the washing drum is partially submerged in this washing bath.
  • the laundry drum creates agitation in the upper layers of this washing bath and leaves practically without large movements the lower layers of this bath which are confined in a hollow bottom of the tank of this washing machine where deposit or accumulate the not yet dissolved part of the detergent dose introduced.
  • This part of undissolved detergent is thus sheltered, does not participate in washing the laundry, is evacuated as a pure waste during an emptying of the tank of this washing machine and results in a poor washing result.
  • Another known solution consists in closing, in the bottom of the tank, the deep recess giving access to the drain pump when this pump is stopped. This solution prevents the not yet dissolved part of the dose of detergent introduced into the washing machine's tank from accumulating and staying sheltered in this deep hollow part.
  • the aim of the present invention is to avoid the above drawbacks, which makes it possible to produce a washing machine with a horizontal drum which creates turbulence in the detergent bath both at the level of the bottom or lower hollow part of the tank and at level of the upper layers of this bath.
  • a horizontal washing machine provided with internal ribs for stirring and washing the laundry is characterized in that the laundry drum comprises, around its periphery, blades generating turbulence, angularly spaced, and visible on its outer surface .
  • a washing machine 1 according to an exemplary embodiment partially and schematically illustrated in FIG. 1 comprises a bodywork 2 indicated in phantom, a tank 3, a cylindrical laundry drum 4 rotating around a horizontal axis 5.
  • the laundry drum 4 is provided on its inner cylindrical surface with internal longitudinal angularly spaced ribs 8. These ribs 8 are intended to lift the laundry located inside this drum 4 during rotation of this drum and drop it under the effect of its weight to achieve both a mixing of the mass of this laundry and a mechanical action of washing this laundry independently of a chemical washing action carried out by a detergent introduced into the tank 3 and dissolved in a water 9 to form a detergent bath 11 which covers a lower part of the tank 3 and a part of the drum 4.
  • the tank 3 comprises in its lower part a bottom 10 deep recess giving access to a drain pump 12, schematically shown in broken lines.
  • a drain pump 12 schematically shown in broken lines.
  • a large part of this dose of product dissolves by crossing the body of water 9 and forms a detergent bath 11.
  • a small part of this dose of product not yet dissolved reaches the bottom 10 of the tank 3 and is deposited in the hollow of this bottom. If no turbulence is produced in this detergent bath 11 at the level of this bottom 10 of the tank 3, this part of detergent product which is there remains undissolved and will be evacuated in pure loss during an emptying of the tank 3 by pump 12.
  • a washing machine 1 with a horizontal drum 4 provided with internal ribs for stirring and washing the laundry 8 is characterized in that the laundry drum 4 includes, around its periphery, turbulence-generating blades 15, angularly spaced and visible on its outer surface.
  • the laundry drum 4 with its internal mixing and washing ribs 8 creates agitation in the upper layers of the detergent bath 11 while the blades 15 of this drum 4 generate intense turbulence in the lower layers of this detergent bath 11 which are located at the bottom 10 in the hollow of the tank 3.
  • This intense turbulence dislodges the part of detergent not yet dissolved therein, lifts it up in this bath 11 and forces it to dissolve completely and actively participate in the chemical action of washing clothes.
  • the dose of detergent introduced into the tank 3 is thus completely dissolved and participates in its entirety in the chemical action of washing the laundry. No unnecessary loss of undissolved detergent usually found in known washing machines is thus recorded.
  • a dose of detergent usually provided for washing in a known washing machine can thus be advantageously reduced appreciably in the case of washing the laundry in a washing machine produced according to the invention and without compromising a good result desired wash.
  • a shaking detergent bath with a well-dissolved detergent increases its wetting effect, extends its chemical washing action throughout the mass of this laundry and gives a better washing result than that usually obtained in known washing machines.
  • the turbulence-generating blades respectively have the shape of a flat plate schematically represented at 15 in FIG. 1 and at 18 in FIG. 2.
  • the turbulence-generating blades respectively have the shape of a corrugated sheet schematically represented at 23 in FIG. 3 or a sheet folded in a zigzag not shown.
  • the laundry drum 4 comprises a ferrule or side wall constituted by a metal sheet provided with perforations and not shown openings wound in a cylinder and in which internal longitudinal ribs for mixing and washing 8 are directly formed by folding.
  • the ribs 8 thus form an integral part of this ferrule and the drum 4 presents towards the outside a side wall provided with spaced longitudinal recesses which are external faces of these internal longitudinal brewing and washing ribs 8.
  • the turbulence-generating blades in the form of flat plates 15, 18 or in the form of corrugated sheets 23 or folded in a zigzag shape are radially formed in longitudinal recesses of the drum shell constituted by the external faces of the ribs of stirring and washing 8, and along the axis of these hollows.
  • These blades are either integral parts of these ribs 8, or attached and fixed by welding, gluing, screwing, riveting, fitting, or any other known means of fixing to the hollow external faces of these ribs 8.
  • the laundry drum comprises a ferrule constituted by a metallic foil provided with perforations and openings and wound in a cylinder, and internal longitudinal brewing and washing ribs shown diagrammatically at 17 in FIG. 2 or at 20 in FIG. 3 and provided in the axis of their hollow external faces , turbulence-generating blades 18 (FIG. 2) or 23 (FIG. 3) are fixed on the inner surface of this ferrule opposite the corresponding openings which leave these blades, visible towards the outside, in other words accessible from the outside.
  • the ribs 17 and 20 are fixed to this shell of the laundry drum by any known means of fixing and the blades 18 and 23 are either integral parts of these ribs 17 and 20, either attached and fixed to the hollow external faces of these ribs 17 and 20.
  • the turbulence-generating blades protrude outside, relative to the cylindrical surface of the shell of this drum.
  • the turbulence-generating blades are set back and at most flush with the cylindrical surface of the shell of this laundry drum.
  • the turbulence-generating blades are fixed angularly spaced on the outer surface of the shell of this laundry drum independently of the interior longitudinal ribs for stirring and washing this drum, and following, either generators or longitudinal lines, or helices or helical lines, or sigzag lines.
