Definitions

  • This invention relates to a dispensing device for a dishwasher or a laundry washing machine and comprises a detergent storage compartment connected to a dispensing chamber in which a screw conveyor is rotatably arranged, the dispensing chamber being provided with an outlet opening connected to a treatment chamber for the dish or the laundry.
  • detergents in the form of powder, tablets, pastes and liquids for dishwashers and laundry washing machines. These detergents are usually placed in a box in the machine from which they at a suitable time during the washing process are automatically dispensed into the treatment chamber.
  • powder which is the most common detergent
  • the operator normally measures up a quantity corresponding to the need for each part of the washing process and fills these quantities in separate boxes which are opened successively towards the treatment chamber during the washing process.
  • the purpose of this invention is to achieve a dispensing device for a powder detergent the dispensing device being shaped such that it, as far as possible, prevents damp from penetrating into it at the same time as a proper conveying and dispensing function should be achieved also if the powder becomes clogged for any reason. This is achieved by means of a device having the characteristics mentioned in the claims.
  • FIG. 1 shows a perspective view of a dishwasher for which the present invention is to be used
  • Fig. 2 is a vertical section of the dispensing device in a non active position when the door of the dish washer is closed
  • Fig. 3 shows an enlargement of a detail in Fig. 2
  • Fig. 4 shows the same section as Fig. 2 but in a dispensing position.
  • the dishwasher shown in Fig. 1 has a casing 10 with a door 11 normally covering an opening to a treatment chamber 12.
  • the treatment chamber is in a conventional manner provided with baskets 13 that can be pulled out and on which the dish is placed and wash arms, not shown, through which the water is sprayed towards the dish.
  • the door 11 which is comparatively thick, comprises an outer and an inner layer and encloses a storage compartment 14 in which a larger quantity of detergent is filled through a fill opening 15 arranged at the upper edge part of the door.
  • the lower part of the compartment 14 is shaped as a hopper and encloses a toothed wheel 16 turnably arranged about a horizontal shaft 17 and having several openings 18.
  • the lower portion of the compartment 14 ends in a cylindrical chamber 19 in which a screw conveyor 20 is rotatably arranged.
  • the threads 21 of the screw conveyor engage the teeth of the wheel 16 such that the wheel is turned when the screw is rotated.
  • the sealing washer is by means of a screw joint 24 or in any other suitable way fixed to the screw conveyor 20 between an inner and an outer clamping plate 25 and 26 resp. In its sealing position the washer abuts an edge portion 27 of the cylindrical chamber 19.
  • the other end of the screw is a tube shaped part 28 with a groove for an annual sealing 29 abutting the inner wall of the cylindrical chamber 19.
  • the end of the tube shaped part 28 is covered by an end wall portion 30 fixed at the tube shaped part and having a central threaded opening in which a first threaded portion 31 of a shaft 32 is inserted.
  • the end wall portion 30 is provided a stop 33 and 34 resp. extending at each side of the end wall and cooperates with pins 35 and 36 resp. arranged at the first threaded portion.
  • the shaft 32 also is provided with a second threaded portion 37 the threads being directed in the opposite direction with regard to the threads of the first portion 31.
  • the threaded portion 37 extends through a central threaded opening of a cylindrical follower 38 arranged to rotate in a groove 39 established between the outer end of the cylindrical chamber and an end sleeve 40 surrounding the chamber.
  • the follower 38 is also provided with a groove 41 at the side which is opposite the end wall portion 30.
  • the groove 41 is a part of a circle and surrounds the major part of the periphery of the circle one end of the groove being an abutment surface for a pin 42 arranged at a sleeve 43 fixed to the shaft 32.
  • the sleeve 43 is driven by means of an electric motor, not shown, which is activated by means of the program controller of the dish washer.
  • the device operates in the following manner.
  • the program controller of the dish washer activates the electric motor, not shown, which rotates the sleeve 43 and hence the shaft 32.
  • the shaft 32 will be moved to the left in Fig. 2 with a large force since the follower 38 in this position operates as a fixed nut because of the existing friction forces between the follower and the part surrounding the groove 39.
  • the first threaded portion 31 rotates in the end wall portion 30 since the end wall portion in this position serves as a fixed nut because of existing friction forces between the screw conveyor 20 and the surrounding chamber 19 which means an additional superposed movement of the screw conveyor to the left in Fig. 2.
  • This means that the screw conveyor, without being initially rotated, will move to the left in Fig 2 such that the flexible sealing washer 23 is disengaged from the edge portion 27 of the chamber 19. During this motion the washer 23 moves from a deformed stage to a flat stage.
