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 arranged with bottom-side drainage channels is arranged, the first section, which is essentially aligned with the fresh water nozzle, branches at its end into two further sections with a flow direction directed against the main flow direction of the inlet water.
  • Such a detergent dispenser is known from DE-OS 28 13 366.
  • individual flows which are not clearly definable arise and which also form a vortex zone in their contact area with the main flow of this section.
  • These individual flows largely form a counterflow in this further section, which consumes part of the energy in the main flow, so that the jet energy of the water jets emerging from the lateral drain holes and directed onto the chamber walls is sometimes insufficient to detergent from the Rinsing out the assigned chamber satisfactorily.
  • the invention has for its object to improve a mutually interfering influence of the main flow and individual flows in a detergent dispenser described above so that the necessary beam energy for satisfactory rinsing of the detergent is maintained.
  • this object is achieved in that at the end of the further channel sections there is a third channel section, the flow direction of which essentially corresponds to that of the first channel section.
  • the dreaded individual flows in the third channel section can be combined to form an overall flow which no longer comes into contact with the main flow of the further section. A resulting energy consumption of this main flow is therefore excluded.
  • a further embodiment of the invention in particular, contributes to calming the flows in the channel sections and reducing the flow noise, in which there are partition walls between the first and the third and between the third and the further channel section, which are in the branching area at the end of the first Channel section are connected to each other by an arcuate wall which is shaped approximately parallel to the branch flow in the deflection area.
  • 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 to the detergent chambers which can be filled with detergent powder.
  • these first sections 9 and 10 drainage holes 11 and 12 leading to the detergent chambers below are already provided. If certain conditions allow, these drain holes 11 and 12 can also be omitted.
  • 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.
  • 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.
  • the respective water guide channel branches At the end of the first sections 9 and 10 delimited by the partition walls 15 to 18, the respective water guide channel branches, the further sections as channel branches 19 to 22 lying parallel to the first section 9 and 10, respectively, but through which the supply water flows in the opposite direction.
  • 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.
  • the configuration of the water guide channels according to the invention comprises, at the end of the first channel sections 9 and 10 in the branching area, arcuate wall sections 27, by means of which the partition walls 15 to 18 are extended in the deflection area.
  • the arch-shaped wall sections 27 are followed by further partition walls 28 lying parallel to the first partition walls 15 to 18.
  • third channel sections 29 are formed in each case, which connect to the respective end of the further channel sections 19 to 22.
  • drain holes 30 At the bottom of these third channel sections 29 there are also drain holes 30 through which the inlet water which has entered the third channel sections 29 can flow into the detergent chamber located below.
  • a wedge 31 which supports the formation of laminar flows in the deflection area.
  • channel sections which are connected in series and which are folded into one another leads to a calming and equalization of the currents in the individual channel sections, in which vortex formation and congestion are largely avoided.
  • the curvatures within the flow areas also lead to a considerable reduction in noise, because air bubbles contained in the flow also swim comfortably without being stimulated to vibrate due to irregular changes in direction.
  • the flow directions within the third channel sections 29 can also be seen from FIG. 3 using the symbols. It can be seen from this that the flow in each of these channel sections is rectified with the flow in the first channel sections 9 and 10.
  • FIG. 4 another embodiment of the deflection area can be seen on the basis of a detail IV from FIG. 2.
  • the arcuate partition sections 27 are conical as conical sections 32.
  • the flow energy can be concentrated in the areas of the drain holes by such a measure.
  • the dividing line is to be placed in the bottom region of the water guide channels in order to be able to demold appropriately designed plastic parts of the water guide component.
