Description

LAUNDRY WASHING MACHINE EQUIPPED WITH A POT OF LAUNDRY PRODUCT

DUAL PURPOSE

  The invention relates to a linen washing machine.

  with a jar of powder or liquid washing products

  of, arranged above a tank and comprising a horizontal lateral water inlet for the supply of water to the product container, a conduit allowing, by overflow the passage of the diluted products from the container into the internal space of the tank

  and finally a siphon ensuring total drainage of the residual water

  dual contained in the pot after a washing operation.

  Such a machine is known from the European patent application

No. 099998.

  The purpose of European patent application O 099 798 is

  object a washing machine that has a pot of product in it

  dre or liquid. In the use of product pots

  powder or liquid sive arises, the problem of fouling

  jars with viscous liquid detergents, detergents which agglomerate with the powdered product, during a double

  use. There is also, for the same reasons, the problem

  me of the plugging by clogging of the drain pipes

said pots.

  The product container described in the cited patent application is provided with a water injection end, mounted at

  near the bottom and associated with a tubular supply duct

  water ration. The tubular conduit cooperates with a siphon on the one hand, by a bypass which supplies water to the siphon and on the other hand by the injection end which causes a

  depression at the inlet of said siphon to prevent clogging

tion.

  The device described has the drawback of â-

  be complex, to have a network of tubes that can lead to

  accidental plugging, for example by depressing effect

  sion that can generate the siphon when draining the water

  remaining in the pot at the end of a la-

  vage. The subject of the invention is a washing machine for

  laundry with a jar of powder or liquid detergent

  designed to avoid fouling and waterlogging

  means of emptying by the various detergents. She is-

  characterized in that the pot has a double wall one

  inside the other outside, the space between the double

  ble wall being in communication on the one hand, with the arrival

  of water via a water inlet mouth

  on the outer wall and on the other hand, with the volume

  containing a pot through at least one hole

  swam on the inside wall, the water coming from the water inlet and feeding the tank is no longer conducted by a network of tubes liable to become blocked; the water is channeled through the double wall. Sealing of the holes is no longer possible because the little product that passes through the holes dilutes in

  the water contained in the double wall.

  In a preferred form of the invention, the pot can be composed of at least two removable containers, one upper forming the inner wall, the other lower

  forming the outer wall, both substantially parallel

  lepipedic and fitting one inside the other vertically, to form on the one hand, a double vertical partition and a

  double bottom and on the other hand, a siphon for emptying the drain

  lower container. The fitting of the upper containers and

  lower allows easy cleaning of the siphon, cleaning

  latently rare because the residual water circulating in the space included in the double wall contains in concentration only

very little detergent.

  Advantageously, the siphon can be formed of a

  part, of a vertical tube secured to the bottom of the lower container

  laughing, molded with it and crossing it to communicate with

  the internal space of the tank and on the other hand, a sleeve

  substantially vertical cylindrical, closed in its upper part,

  molded into the bottom of the upper container and top con-

  centrally said tube. So when disassembling the detergent container the siphon breaks down into two very

  easily accessible for possible cleaning.

  In a particular form of the invention, the hole (s) in the form of a puncture, arranged on the inner wall, is (are) a nozzle (s) giving the jets an orientation parallel to the plane of the wall or, when the wall is curved, in the plane tangent to the surface of the wall. The holes can have a completely different shape such as for example the shape of a projection at the periphery of which would be arranged holes, in the shower, sending the water parallel to the surface

  on which the projection has been arranged.

  In another preferred form of the invention

  tion, the holes forming nozzles can be placed so as to produce a series of circularly oriented jets. The water jets from the holes cause movement in the pot

  of rotating water for mixing the water and the

  ge. Alternatively, the nozzle holes are arranged

  on the inner wall forming the bottom of the upper container

  laughing, the movement of the water is then called "velodrome movement". In addition to a rotating movement, the holes thus placed cause an upward movement of the water contained in the pot, a movement which raises, when they exist, the

  washing powder agglomerates to carry them towards the

overflow duit.

  In another preferred form of realization

  tion the interior and exterior walls of the pot constitutes a double bottom. The side walls of the two containers which

  fit together then come into contact with each other, leaving

  sant only a space forming a double bottom as well as a

  space allowing laterally a communication between the dou-

  ble bottom and water inlet mouth.

  The following description and the drawings illustrate

  an embodiment of the invention.

  Figure 1 shows a perspective view of the washing machine according to the invention, with its pot

produced.

  Figure 2 is a perspective view of a jar

  washing powder or liquid.

  Figure 3 shows a longitudinal section

  of a product jar according to the invention.

  Figure 4 is a top view corresponding

in the pot of figure 3.

  Figure 5 shows a longitudinal section of the pot

  to product shown in Figure 2.

  Figure 6 is a top view of the pot of the

figure 2.

  Figure 1 shows a top-loading washing machine 1, with its body door 2 open. Below door 2 is a door 3

  tank. Parallel to the plane of the frame of door 3 is fitted

  swam a fixed tray 4 for laundry products and in particular a

  jar 5 of washing powder or liquid.

  FIG. 2 is a perspective view of the pot 5.

  In this embodiment according to the invention the pot

  consists of two substantially parallelepiped containers

  ques, an upper container 6 mounted by vertical interlocking in a lower container 7. The interlocking of the containers 6 and 7 allows; by the fact that the upper container 6 has an external volume less than the internal volume of the container 7, to produce a double wall forming on the one hand, a vertical double partition 8, total or partial and on the other hand, a double bottom 9 total or partial. A water inlet 10 responsible for injecting water into the pot 5 is placed in front of a mouth 11 which communicates with the space between the two walls, this space is itself in communication with holes 12 in the form of a 'nozzle. A part of the pot removed makes it possible to show, in addition to the double bottom 9, a siphon 13 whose function is to empty the lower container 7 and therefore the pot 5, by siphoning the water contained in the bottom of the container 7 between the two walls. The siphon is produced on the one hand, by a molding during the molding of the lower container 7 of a vertical tube 14

  which crosses the bottom of the container to communicate with the

  internal space of the tank and on the other hand, by molding with the upper container 6 of a substantially vertical sleeve 15

  cylindrical and closed at the end, in its upper part 16. The man-

  chon 15 fits concentrically during assembly of the receptacle

  upper pient 6 in the lower container 7, leaving a gap between the upper part 16 closed and the end

high of tube 14.

  The contents of the jar formed by a detergent

  diluted is poured into the internal space of the tank by overflow

  when the mixture arrives at a pipeline

17 drain.

  FIG. 3 represents a jar of detergent

  ve in longitudinal section and having a double vertical partition 8 and a double bottom 9. In this embodiment according to the invention, the water inlet 10 injects the water into

  mouth 11 to invade the space between the double pa-

  King. The water contained in this space gushes into the upper container 6 through the holes 12. The holes 12 can be, in order to simplify manufacture, made by molding either on the bottom of the container 6 or on the vertical partition of said

  container, either simultaneously on the bottom and the vertical partition

  wedge to form a series of nozzles. Each of the nozzles has

  the shape of a puncture made by molding or if the reci-

  pient is metallic, by cutting the sheet metal and stamping in order to form a projection and create a hole whose rectangular or arc-shaped section is a substantially surface

  perpendicular to the surface in which it was made.

  Thus the water jets leaving these nozzles parallel to the wall surface make it possible, when mixing the products with the water, either a turbulent regime when the jets are oriented in opposition, or a rotating regime when the jets are circularly oriented. Arrows on

  different figures give the orientation of the water jets

  trant in the volume containing the pot. In Figure 3 is re-

  presented in section, the siphon 13 composed of the tube 14 integral

  of the lower container 7 as well as the sleeve 15 itself

lid of the upper container 6.

  Figure 4 shows the direction of water movement in the case of a circular orientation of the jets during

  of a water-detergent mixture.

  Figure 5 shows a double bottomed pot 9

  in longitudinal section. In this embodiment,

  form of the invention, the space between the double wall is reduced

  mainly at a space between the two bottoms of the two reci-

  pients space occupying in the horizontal plane all or part of the two horizontal walls. The holes 12 are then placed only in the bottom of the upper container. In a particular form shown in Figure 6, the holes are placed and their nozzles oriented so as to cause in the pot of rectangular section a movement called "velodrome" of the injected water. In this embodiment, a

  rotating movement with, in addition, a vertical component

  placing the water-product mixture upwards in sensitive layers

  flat and horizontal, in this way the agglomerations

  powdered laundry detergent rats are lifted by the

  of water to be then poured into the space

  dull of the tank through the overflow pipe.
