  • a washing system for a dishwasher comprising a wash arm rotatable about a rotation axis R, the wash arm including at least one wash arm segment extending from the rotation axis R.
  • the at least one washing arm segment comprises a plurality of dispensing elements for dispensing a fluid medium, wherein according to the invention each washing arm segment comprises at least three dispensing elements, ie comprising a total of N dispensing elements, with N ⁇ 3.

  • an internal angle within the meaning of the invention always means the smaller of these two angles.
  • a washing system with dispensing elements arranged in this way has the advantage that the dispensing elements are optimally arranged, so that on the one hand sufficient and good coverage of the areas of the dishwasher in which dishes are positioned for cleaning is ensured, while at the same time ensuring that one Overlapping the delivery areas of the individual delivery elements, typically dispensing cone, greatly reduced and preferably completely avoided, at least up to a certain distance from the dispensing elements, which is relevant for flushing the dishes to be inserted into the dishwasher, in particular the distance of the dispensing elements to the positions in which typically the items to be washed are positioned in the dishwasher, for example in corresponding Waschlcörben.
  • the washing system therefore provides an optimized distribution of the dispensing elements on a washing arm segment, moreover, such an arrangement of dispensing elements in a Wascharmsegment also has the advantage that a flow optimization in the supply of the fluid medium is realized within a feed channel within the Wascharmsegments that that leads to an overflow of Nozzle is greatly reduced by the fluid medium within the feed channel.
  • a particularly low-loss system is made available which thus saves energy; on the other hand, the constancy and the quality of the delivery of the fluid medium are improved by the delivery elements.
  • the washing system of the present invention provides a flow-optimized and thus energy-efficient system which, moreover, with less effort, in particular with lower energy expenditure, delivers improved rinsing results.
  • all dispensing elements are arranged on one side of the washing system, namely on the side facing the dishes.

In particularly preferred embodiments, the difference is even at least 3 ° or even at least 5 °.
  • the difference between two internal angles is always at least 2 °, but in at least some other delivery elements the difference is greater, for example at least 3 ° or at least 5 °, so that differences between two internal angles between "adjacent" delivery elements, ie between two discharge elements, which have the least difference in terms of their distance r from the axis of rotation R, always be at least 2 °, but in some cases also larger.
  • the delivery elements A n on a Wascharmsegment are preferably in each case at different distances r n from the rotation axis R. arranged, which allows a particularly preferred distribution of the dispensing elements in the radial direction and therefore enhances the above effects.
  • the wash arm comprises at least two Wascharmsegmente extending from the axis of rotation R in different directions, wherein preferably exactly two Wascharmsegmente are provided which extend from the axis of rotation R in different directions, in particular in opposite directions.
  • the wash arm represents a particularly preferred weight distribution about the axis of rotation R, which is favorable for the rotational movement.
  • the distribution and the interaction of the delivery elements is supported on the individual Wascharmsegmente in a particularly advantageous manner, so that a good rinsing result can be achieved.
  • the washing system is formed so that a cross section of the washing arm is formed in a plane perpendicular to the rotation axis R is substantially S-shaped.
  • the washing arm for example, in a plan view, that is, in a view of the wash arm in the direction of the axis of rotation, S-shaped.

  • Such a design of the washing arm causes the washing arm, taking into account the special arrangement of the dispensing elements according to this invention, can be produced with low material costs and thus with low weight.
  • the internal angle ⁇ max for the delivery element A max which has the largest distance r max on a Wascharmsegment, is very large, for example 40 ° or more
  • this plays an increased role which is particularly clear in that the (imaginary) connecting line between the axis of rotation R and the delivery element A max , seen in plan view, that is to say in the direction of the axis of rotation R, largely extends over areas runs, which are not above or below the Wascharmsegment, ie in this area no material of the Wascharmsegments is present, which reduces the total weight.
  • the number of the dispensing element and / or the position of the dispensing elements on a wash arm segment is different than the number and / or position of dispensing elements on another wash arm segment of the washing system.
  • the individual Wascharmsegmente with respect to the distance r n and the inner angle ⁇ n are formed identical, however, a different arrangement of the discharge elements on individual Wascharmsegmenten causes the items to be washed by each of the Wascharmsegmente different with the fluid medium is applied, which further improves the rinsing result.

  • the center line therefore divides the Whyarmsegmente, with respect to a cross-sectional plane or viewing plane which is perpendicular to the axis of rotation R, in two substantially equal parts.
  • This embodiment has the advantage that as uniform as possible flow velocities are generated, so that turbulences within the feed channel are largely avoided.
  • the taper of the feed channel is formed with increasing distance from the axis of rotation to an extent substantially proportional to the decrease in a volume flow of the fluid medium with increasing distance from the axis of rotation caused by the delivery of the fluid through the delivery elements ,
  • This ensures particularly effective that the flow rate within the feed channel remains largely constant.
  • the resulting avoidance or at least reduction of turbulence on the one hand leads to the fact that the washing system is energetically more favorable, moreover, that the discharge characteristic of the delivery elements can be controlled and maintained particularly accurately, furthermore very small fluctuations of the discharge characteristic arise.
  • all of the dispenser elements of the wash arm segment are disposed in a region from a centerline of the wash arm segment to a side boundary of the wash arm segment which is forward in the direction of rotation of the wash arm or in the direction of movement of a wash arm segment.

  • the dispensing elements are arranged more densely in an outer region of the Wascharmsegments than in an inner region of the Whyarmsegments. This is preferred because due to the rotational movement of the washing system during the flushing operation, the radially outer regions must cover a larger area and a larger area than the radially inner areas. In this way, a uniformly good dishwashing result is achieved, regardless of where in the dishwasher the dishes are located, for example in an outer area of a washing basket or in an inner area.
  • Such compaction of delivery elements in an outer region can be provided for both a single Wascharmsegment, but a compression in an outer region is particularly preferred in terms of several, cooperating Wascharmsegmente or an entire washing system with different Wascharmsegmenten.
