Definitions

  • the invention relates to a detergent dispenser for a laundry treatment machine, which contains a housing that is open on one side and a drawer that can be moved through this opening and has a plurality of compartments for detergents and washing aids that are open at the top and a water guide channel provided with bottom drain holes, which has a first channel section which is guided in the inlet direction and at least two branch sections which branch off therefrom and run against the inlet direction.
  • Such a detergent dispenser is known from DE-OS 28 13 366, which needs to be improved with regard to the noises generated when fresh water flows in. This is the object of the present invention.
  • this object is achieved in that at the end of the first channel section in the branching area a wedge is arranged with its tip directed towards the flow of the incoming water.
  • a particularly advantageous development of the invention is to be seen in the fact that the wedge surfaces are curved in a concave manner. This avoids discontinuities in the flow-directing walls. Vibrations on the air bubbles are therefore suppressed to an increased extent.
  • the wedge surfaces have gutters running along the flow.
  • the water guiding component 1 designed as a cover for the housing of a detergent dispenser has fresh water nozzles 2, 3 and 4 on its rear wall.
  • openings 6, 7 and 8 are arranged opposite the fresh water nozzles, of which the openings 6 and 8 belong to first sections 9 and 10 of the water guide channels leading preferably to detergent chambers which can be filled with washing powder.
  • first sections 9 and 10 drainage holes 11 and 12 leading to the detergent chambers below are already provided.
  • the opening 7 opposite the fresh water nozzle 3 belongs to a water guide channel 13 which serves to supply the inlet water (not shown) required for emptying the fabric softener chamber arranged under the drain holes 14.
  • drain holes 23 and 24 are provided in a row one behind the other.
  • the washing powder which is stored in the detergent compartments (not shown) is rinsed by the water jets flowing through the drain holes 23 and 24 and is conveyed from the feed water through the antechamber 5 into the washing container.
  • channel sections 10, 20 and 22 in FIG. 3 indicate the direction of flow of the inlet water in accordance with the arrows in FIGS. 1 and 2.
  • Fig. 3 are further by the side walls 25 and the partition walls 26 below arranged in the channel sections detergent chambers.
  • the detail 30 encircled by dash-dotted lines in the illustrated embodiment is the branching area at the end of the first channel section 9 or 10.
  • a wedge 27 is arranged according to the invention, the wedge 27 of which points at the flow of the incoming water in the first Channel section 9 or 10 is directed.
  • This tip clearly divides the flow of the incoming water and without eddies.
  • the wedge surfaces which in the exemplary embodiment shown in FIGS. 1 to 3 are curved in a concave manner, also guide the partial flows without formation of eddies into the subsequent channel branches 19 and 21 or 20 and 22. The calming of the flow that can be achieved and the avoidance of eddies are accompanied by this a reduction in the flow noise within the channels.
  • the flow can be kept particularly laminar in the branching area if the wedge surfaces have gutters running along the partial flows.
  • This embodiment is shown in FIG. 4, in which a wedge 27 is shown in section at the section line IV-IV in FIG. 1. From this illustration it can be seen that the wedge surfaces 29 are formed in addition to the concave, arch-like configuration.
