Definitions

  • the invention relates to a washing machine comprising a tank intended to contain the washing or rinsing water, the bottom of which has a cavity with a substantially horizontal opening from which a drain pipe leads leading to a drain pump.
  • a washing machine comprising a tank intended to contain the washing or rinsing water, the bottom of which has a cavity with a substantially horizontal opening from which a drain pipe leads leading to a drain pump.
  • a drain pipe leads leading to a drain pump is for example shown in US Pat. No. 3,084,530.
  • the cavity located at the lowest point of the tank acts as a sump allowing regular operation of the pump, without defusing, until the tank is effectively emptied.
  • This arrangement which is very common, has the drawback of collecting solid bodies in the pipe leading to the pump.
  • These solid bodies are, on the one hand, the soap or detergent powders entrained in the filling water of the tank, at the start of washing, and not completely dissolved when they reach the bottom of the tank.
  • These powders, accumulated in the cavity and the drain pipe, will not be brewed during washing, because they are distant from the bodies of water set in motion by the drum or the agitator. They are evacuated at the start of emptying, constituting a loss which can reach 2091 of the powder initially placed in the machine by the user.
  • Solid bodies are on the other hand foreign objects, debris, pins, buttons, coins ... accidentally introduced with the laundry to be washed or detached from this laundry. Passage through the pump can damage the pump, block it, or block the filter that protects it.
  • the invention aims to limit the fall of these solid bodies in the drain pipe. It is characterized by the fact that the drain pipe opens onto the internal volume of the tank through an orifice located on at least one substantially vertical side wall of the cavity, orifice in the form of a horizontal slot located above the bottom of the cavity .
  • the cavity then behaves like a receptacle in which the solid bodies collect without being sucked in by the drain pump.
  • the powder :, soap or detergent not dissolved during filling can be brewed by the rotation of the drum or the agitator.
  • the invention is here applied to a washing machine of the rotary washing drum type (not shown) with horizontal axis and top loading.
  • the tank is, in this example, made of injected thermoplastic material, such as lightened polypropylene or loaded with fibers. It comprises a body formed in one piece of a substantially cylindrical ferrule 1 of revolution and of a flange 2 in the center of which is a housing 3 for a drum bearing. At the top of the shell 1 opens a hopper for loading the linen 4.
  • the tank is closed by a removable flange 5 forming a cover, also pierced with a housing 6 for drum bearing.
  • Figures 1 and 2 show these two separate parts of the tank, Figure 3 shows them assembled, but neither the staples or other connecting devices, nor the joint inserted between these two parts are shown.
  • the tank has, below its ferrule 1, a cavity or first sump 7 of parallelepiped shape in the example drawn.
  • the cavity 7 is open on the enclosure of the tank.
  • two vertical walls 8, 9 are arranged longitudinally by relative to the shell, a third wall 10 is transverse, as for the fourth wall, also transverse, it is constituted by an element 11 belonging to the removable flange 5, which comes to adapt to the cavity 7 when the tank is assembled (FIG. 3).
  • the bottom of the cavity is substantially horizontal. The depth of the cavity is much less than its width, for example three times less.
  • the vertical wall 8 is pierced with a horizontal slot-shaped orifice 12 located at a distance from the bottom of the cavity.
  • This slot 12 opens into a compartment 13 having no other communication with the enclosure of the tank and substantially parallel to the cavity 7, also located under the cylindrical surface of the shell.
  • the compartment 13 is open on one side and communicates with a second sump 14 located below and from which leaves, at the lowest point, a conduit 15 intended to be connected to the drain pump.
  • the second sump 14 is constituted by a downward extension of the tank, constituting a sort of double bottom over part of the length of the generatrices of the shell 1.
  • the succession of these volumes 7, 13, 14 is intended to impose a drain path on the water. This path is designated in the figures by the arrows T.
  • This path is designated in the figures by the arrows T.
  • the fact that the slot-shaped orifice 12 is not at the bottom of the cavity 7 prevents the solid bodies fallen at the bottom of this cavity from being entrained during the emptying of tank.
  • the slit shape of the orifice 12 also contributes to obstructing the suction of these solid bodies.
  • the cavity 7 is easily accessible from inside the tank.
  • the user accesses it by hand through the hopper 4, after opening the loading door of the washing drum and a diametrically opposite hatch in the shell of the drum. It is thus possible to periodically inspect, without dismantling the tank, the cavity 7 in order to remove the solid objects therefrom.
