Definitions

  • the present invention relates to a washing system for a dishwasher and a dishwasher which is equipped with such a washing system.
  • a washing system is typically designed in the form of so-called washing arms to which a fluid medium, usually a cleaning liquid, is applied, the fluid medium then being dispensed via dispensing elements, in particular nozzles, and directed onto the dishes to be cleaned.

  • a dishwasher which comprises a wash arm which has a non-rectilinear main axis with a kink which is designed so that this leads to a change in the flow direction of the liquid that is transported within the wash arm in order to achieve a change in direction Apply pressure to the rinse arm so that it is driven in the direction of rotation.
  • Another wash arm is known on which different spray nozzles are arranged, at least some of the spray nozzles being adjustable or coverable so that the individual spray nozzles can also be activated or deactivated so that the wash arm can be adjusted depending on the load status of a dishwasher .
  • a wash arm is also known on which a plurality of nozzles can be arranged in a distributed manner on wash arm segments, these nozzles being inserted into openings in the wash arm.
  • a washing system for a dishwasher in particular for a commercial dishwasher, according to claim 1
  • a dishwasher in particular a commercial dishwasher, according to claim 15.
  • Claims 2 to 14 relate to particularly advantageous embodiments of a washing system according to claim 1.
  • a washing system for a dishwasher which comprises a wash arm which is rotatable about an axis of rotation R, the wash arm comprising at least one wash arm segment which extends from the axis of rotation R.
  • the at least one wash arm segment comprises several dispensing elements for dispensing a fluid medium, wherein according to the invention each wash arm segment comprises at least three dispensing elements, ie comprises a total of N number of dispensing elements, with N ⁇ 3.
  • the individual delivery elements of a wash arm segment are arranged in different positions of the wash arm segment in such a way that a connecting line between the axis of rotation R and a first delivery element A 1 of the at least one wash arm segment which has the shortest distance r 1 of all delivery elements A n of this wash arm segment to the axis of rotation , with a connecting line between the axis of rotation R and another delivery element A n of the same wash arm segment forms an interior angle ⁇ n .
  • the position of a delivery element A n is therefore determined on the one hand by its distance r n from the axis of rotation R and on the other hand by an angular position relative to an angular position of the delivery element A 1 , which has the shortest distance r 1 of all delivery elements, so that each Output element A n is assigned a distance r n from the axis of rotation R and an interior angle ⁇ n .
  • an associated interior angle ⁇ n is greater than an interior angle ⁇ n-1 of another delivery element A n-1 of the same wash arm segment if the distance r n of the delivery element A n from the axis of rotation R is greater than the distance r n-1 of the delivery element A n-1 from the axis of rotation R.
  • a washing system with delivery elements arranged in this way has the advantage that the delivery 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 it can be ensured that a Overlapping of the delivery areas of the individual delivery elements, typically delivery cones, can be greatly reduced and preferably completely avoided, at least up to a certain distance from the delivery elements that is relevant for washing the items to be washed in the dishwasher, in particular the distance between the delivery elements and the positions , in which the items to be washed are typically positioned in the dishwasher, for example in corresponding washing baskets.
  • the washing system therefore provides an optimized distribution of the dispensing elements on a wash arm segment; in addition, such an arrangement of dispensing elements in a wash arm segment also has the advantage that the flow is optimized when the fluid medium is supplied within a feed channel within the wash arm segment leads to an overflow of Nozzles is greatly reduced by the fluid medium within the feed channel.
  • a particularly low-loss system is made available, which thus saves energy, and on the other hand, the constancy and the quality of the delivery of the fluid medium by the delivery elements are improved.
  • the washing system of the present invention therefore provides a flow-optimized and thus energy-efficient system which, moreover, delivers improved washing results with less effort, in particular with less energy expenditure.
  • All the dispensing elements are preferably arranged on one side of the washing system, namely on the side facing the items to be washed.
  • a washing system that has dispensing elements on both sides, i.e. above and below, for example when a washing system is arranged in such a way that items to be washed can be arranged both above and below the washing system.
  • the delivery elements are arranged on a wash arm segment in such a way that an interior angle ⁇ max for the delivery element A max , which on the wash arm segment has the greatest distance r max of all delivery elements of this wash arm segment from the axis of rotation R, is at least 60 °. In a particularly preferred embodiment, this angle ⁇ max is preferably at least 80 °. The angle ⁇ max is particularly preferably in a range from 60 ° to 80 °.
  • dispensing elements are arranged in such a way that items to be washed or a specific Area of items to be washed are acted upon with the fluid medium by different dispensing elements of an individual wash arm segment without the dispensing elements influencing one another or the dispensing areas or dispensing cones of the dispensing elements overlapping.
  • the delivery elements are arranged on a wash arm segment in such a way that a difference between two interior angles ⁇ n and ⁇ n-1 for two different delivery elements A n and A n-1 on a wash arm segment is at least 2 °. In particularly preferred embodiments, the difference is even at least 3 ° or even at least 5 °.
  • the difference between two interior angles is always at least 2 °, while 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 interior angles between "adjacent" delivery elements, i.e. between two delivery elements, which have the smallest difference in terms of their distance r from the axis of rotation R, always amount to at least 2 °, but in some cases are also larger.
  • the delivery elements A n on a wash arm segment are preferably each at different distances r n from the axis of rotation R arranged, which enables a particularly preferred distribution of the delivery elements in the radial direction and therefore intensifies the above-mentioned effects.
  • the wash arm comprises at least two wash arm segments, which extend from the axis of rotation R in different directions, preferably exactly two wash arm segments are provided, which extend from the axis of rotation R in different directions, in particular in opposite directions.
  • the washing system is preferably designed such that a cross section of the washing arm in a plane perpendicular to the axis of rotation R is essentially S-shaped.
  • the wash arm is S-shaped, for example in a plan view, that is to say in a view of the wash arm in the direction of the axis of rotation.
  • the wash arm is S-shaped or in the form of an inverse or mirror-shaped one S is trained.
  • Such a design of the wash arm has the result that the wash arm, taking into account the special arrangement of the dispensing elements according to this invention, can be manufactured with little material expenditure and thus with low weight.
  • the internal angle ⁇ max for the delivery element A max which has the greatest distance r max on a wash arm segment, is very large, for example 40 ° or more
  • the number of dispensing elements and / or the position of the dispensing elements on one wash arm segment is different from the number and / or the position of the dispensing elements on another wash arm segment of the washing system.
  • the individual wash arm segments may be identical with regard to the distance r n and the interior angle ⁇ n , a different arrangement of the dispensing elements on individual wash arm segments means that the wash ware of each of the wash arm segments differs with the fluid medium is acted upon, which improves the washing result even further.
  • each wash arm segment comprises a feed channel designed as a cavity for receiving a fluid medium and for feeding the fluid medium to the delivery elements, the feed channel being designed so that the cross section of the feed channel extends in a plane perpendicular to a tangent to a center line of the Wash arm segment tapers with increasing distance from the axis of rotation R.
  • the tapering can take place continuously, but it is also possible that a gradual tapering is provided, it is also possible that the tapering takes place partly continuously and partly via steps.
  • the center line is to be understood as a line which, in a plan view of the washing system in the direction of the axis of rotation R, starting from the axis of rotation R in a plane that runs perpendicular to the axis of rotation R, extends in both directions of the extent of the Wash arm segments extends so that the distance between the center line and a front edge of the wash arm segment is the same as the distance between the center line and a rear edge of the wash arm segment.
  • the center line therefore divides the wash arm segments, with regard to a cross-sectional plane or viewing plane that runs perpendicular to the axis of rotation R, into two largely equal partial areas.
  • This refinement has the advantage that flow speeds that are as uniform as possible are generated, so that turbulence within the feed channel is largely avoided.
  • the tapering of the supply channel with increasing distance from the axis of rotation is formed to an extent that is essentially proportional to the decrease in a volume flow of the fluid medium, with increasing distance from the axis of rotation, which is caused by the delivery of the fluid medium by the delivery elements .
  • This ensures in a particularly effective way that the flow rate within the feed channel remains largely constant.
  • the resulting avoidance or at least reduction of turbulence leads, on the one hand, to the washing system being energetically more favorable, and also to the fact that the delivery characteristics of the delivery elements can be controlled and maintained particularly precisely, and there are very slight fluctuations in the delivery characteristics.
  • all delivery elements of the wash arm segment are arranged in an area from a center line of the wash arm segment to a lateral boundary of the wash arm segment, which is at the front in the direction of rotation of the wash arm or in the direction of movement of a wash arm segment.
  • This arrangement of the dispensing elements in an edge region has the effect, in particular, that the fluid medium in the feed channel further reduces the overflow of the dispensing elements, which further improves the energetic efficiency and the washing result to be achieved.
  • the delivery elements are preferably designed as nozzles, and at least not all of the nozzles of a wash arm segment or of a wash system preferably have the same emission characteristics.
  • the radiation characteristics of a nozzle can be influenced on the one hand by the spatial positioning and the position of the nozzle.
  • the radiation area which is typically a radiation cone or a radiation fan, can be essentially rotationally symmetrical, but it can also not be rotationally symmetrical, so that a rotation of the nozzle around its axis also changes the radiation characteristics.
  • a selection of different radiation characteristics of nozzles therefore makes it possible, in connection with the special positioning of the delivery elements on a wash arm segment, to ensure good coverage of the different areas of the dishwasher, for example also to arrange delivery elements more densely, with an overlap of the radiation areas and a mutual negative influence of the Avoid radiation areas that would be caused by this.
  • the delivery elements are preferably arranged more densely in an outer region of the wash arm segment than in an inner region of the wash arm segment. This is preferred because, due to the rotational movement of the washing system during the rinsing process, the radially outer areas must cover a larger area and a larger area than the radially inner areas. In this way, a consistently good washing result can be achieved, regardless of where the items to be washed are located within the dishwasher, for example in an outer area of a washing basket or in an inner area.
  • Such a compression of delivery elements in an outer area can be provided both for a single wash arm segment, however, compression in an outer area is also particularly preferred with regard to several interacting wash arm segments or an entire wash system with different wash arm segments.
  • At least one delivery element A n is designed and arranged on a wash arm segment such that a main radiation direction or a central axis of the delivery area is tilted relative to the axis of rotation R by an angle ( ⁇ 1).
  • At least two dispensing elements A n are designed as nozzles on a wash arm segment, the nozzles each having an elongated dispensing opening so that a longitudinal axis of each of the dispensing openings is defined, which extends in the direction of the longest extent of the dispensing opening , the two dispensing elements being arranged in such a way that the longitudinal axes of the two dispensing elements do not run parallel to one another and a longitudinal axis of at least one dispensing opening lies in such a way that it or its extension does not intersect the axis of rotation R.
  • This different design of the dispensing elements also means that overlapping of the radiation areas can be avoided even better, but at the same time all relevant areas of the dishwasher are reliably covered so that a very good washing result can be achieved.
  • the present invention also relates to a dishwasher, in particular a commercial dishwasher, which comprises at least one washing system according to one of the preceding claims.
  • a dishwasher generally comprises a plurality of washing systems, which are preferably arranged below and / or above, for example, washing baskets, into which items to be washed can be inserted within a dishwasher.
