Definitions

  • the invention relates to a washing machine with a drum and with an injection nozzle for injecting water into the drum.
  • the injection nozzle of such a washing machine should distribute the water as well as possible on the laundry. This can be relatively easily achieved by a nozzle with several very small nozzle openings. However, fine-pored nozzles tend to clog.
  • EP 1 386 996 there is described an injector which has a feed channel which throws water onto a baffle from which it injects in different directions into the drum. In such a solution, however, the water falls approximately along a line on the laundry, resulting in uneven wetting.
  • the injection nozzle allows a more uniform distribution of water.
  • the injection nozzle has at least one tray with a bottom, a first side wall and a second side wall.
  • the baffle wall first follows, then the first side wall, then the floor and then the second side wall.
  • the baffle and the second side wall and the first side wall are located closer to the mouth of the feed channel than the bottom.
  • a line L is defined parallel to the direction X.
  • the mouth, the baffle, the second sidewall and the bottom are projected perpendicular to the direction X radially on this line L.
  • the description now states that the projections of the baffle and the second sidewall on the line L are closer to the projection of the mouth than the projection of the bottom.
  • the washing machine has a housing 2 in which a cylindrical tub 3 is sprung.
  • a drum 4 is provided for receiving the laundry.
  • the drum 4 can be rotated about a horizontal axis of rotation 5 via a drive (not shown).
  • a door 6 is provided transversely to the axis of rotation 5, the frame is connected via a flexible bellows 7 with the tub 3.
  • an injection nozzle 8 is arranged in the bellows 7. This is connected via a not visible in Fig. 1 hose with a pump, via which water can be conveyed through the nozzle into the drum.
  • FIG. 2-7 An advantageous embodiment of the injection nozzle 8 is shown in Fig. 2-7.
  • the embodiment shown consists of a one-piece plastic part. It has a tubular supply channel 10 through which water is introduced into the injection nozzle.
  • the feed channel 10 opens via an orifice 11 in a distribution space 12.
  • the distribution space 12 has an opening 13 towards the drum 5.
  • the lower wall region of the distribution space 12 forms opposite the mouth 11 a baffle 14, which can be seen in particular in FIGS. 2 and 3. This is inclined to the direction X, in such a way that at least part of the water falling from the feed channel 10 to the baffle 14 receives a velocity component in the Z direction.
  • Deflection wall 14 designed sloping towards the direction Z out.
  • the trough 15 has a first side wall 16, which connects bent to the baffle 14.
  • the first side wall 16 merges into a bottom 17 of the tub 15 in a rounding.
  • the bottom 17 goes in turn in a rounding in a second side wall 18 of the tub 15 over.
  • the distribution space 12 is closed off from a substantially flat top wall 19. This is, as shown in particular in Fig. 4, transversely, but not exactly perpendicular to the direction X - it rises to the opening 13 towards something at the top.
  • the mouth 11 is arranged in the top wall 19.
  • the second side wall 18 of the trough 15 extends to the top wall 19, in such a way that top wall 19 and second side wall 18 meet at an angle of approximately 90 °.
  • the distribution space 12 is bounded by a rear wall 23 (see FIG. 4), which extends transversely to the direction Y.
  • the rear wall 23 extends between the bottom 17 of the tub 15 and the top wall 19. It goes over at an acute angle in the top wall 19.
  • Both the bottom 17 of the tub 15, as well as the baffle 14 go in each case a rounding in the rear wall 23 via.
  • the baffle 14 extends to the top wall 19th
  • the distribution space 12 is closed on all sides except for the areas of opening 13 and mouth 11.
  • a lip 26 is arranged between the deflecting wall 14 and the opening 13.
  • the baffle 14 is farther from the mouth 11 than the lip 26, i. the lip 26 is arranged slightly higher than the baffle 14. As a result, more water is conveyed to the tub 15 and it is avoided that too much water exits directly from the baffle 14 through the opening 13.
  • the trough 15 is open toward the opening 13.
  • the edge 27 of the trough 15 adjoining the opening 13 is, seen in the direction X, At least as far from the mouth 11 as the bottom 17 of the tub 15, ie the edge 27 is not higher than the bottom of the trough 15. This ensures that after switching off the water circulation, the water from the tub 15 can drain completely.
  • the injection nozzle 8 is arranged so that the direction X is substantially vertical.
  • FIG. 8 A possible arrangement of the injection nozzle 8 in the bellows 7 is shown in Fig. 8.
  • an opening 40 is provided in the bellows 7, which receives the supply channel 10 of the injection nozzle 8, such that the distribution space 12 between the door 6 and bellows 7 comes to rest.
  • the injection nozzle is designed as a molded part (of one or more materials), as e.g. in Fig. 2-7 is shown.
  • FIG. 8 A second embodiment of the injection nozzle 8 is shown in FIG.
  • the injection nozzle 8 is formed integrally on the bellows 7, i.
  • Injector 12 and bellows 7 are made of the same material and have been combined together, e.g. produced by molding.
  • the injection nozzle is constructed asymmetrically in the direction Z. It is also conceivable, however, a symmetrical structure, as shown in Fig. 10, in which two baffles 14 are provided which divide the coming of the feed 10 water jet into two sub-beams and divert into two trays 15.
  • the exact mass of the injector must be adjusted to the desired water flow rate. For example, at a flow rate of about 8 liters / minute, a feed channel having an inner diameter of 10 mm was used and the tub in the view of Fig. 3 has a radius of curvature of about 11 mm. The rest of the mass can be taken from the full-scale figures 2 to 7.
  • the shape of the individual parts of the injection nozzle may vary.
  • the baffle in the embodiment of Fig. 3 is bent, but it can also be stretched.
  • the transition between the side wall 18 or the rear wall 23 and the top wall 19 may also be curved or locally even interrupted.
