  • Dishwashers in general and program-controlled dishwashers in particular are well known in the art. Separate documentary proof is therefore not required.
  • Generic automatic dishwashers have a washing container that provides a washing compartment. When used as intended, the washing compartment provided by the washing compartment receives items to be cleaned. In this case, a feed opening provided by the washing container is provided for charging the washing compartment with items to be cleaned.
  • the latter can be closed in a fluid-tight manner by means of a flushing door, wherein the flushing door is typically pivotably mounted about a horizontally extending pivot axis.
  • a spray For a loading of items to be cleaned with rinse liquor is a spray.
  • This provides within the washing container rotatably arranged spray arms. These are typically supplied with rinsing fluid via a circulation pump. Depending on the configuration of the dishwasher, two, three or more spray arms can be provided.
  • a spray arm has two groups of nozzles. On the one hand, cleaning nozzles and, on the other hand, drive nozzles are provided.
  • the cleaning nozzles serve in the intended use of the respective generation of a rotatessprühkegels, which is delivered in the direction of the items to be cleaned.
  • the drive nozzles are preferably formed at the end of the spray arm and serve, however, the rotary drive of the spray arm.
  • Both the cleaning nozzles and the drive nozzles are in fluid communication with a distribution chamber provided by the respective spray arm.
  • rinsing fluid conveyed by the circulating pump flows into the distribution chamber of the spray arm, from where both the cleaning nozzles and the drive nozzles are operated with rinsing liquor.
  • Dishwasher provide a variety of possible washing programs available that can be selected by the user, usually depending on the degree of contamination of the dishes to be cleaned.

  • the EP 1586264 A2 describes a dishwashing machine with a spray arm having cleaning nozzles with adjusting units, which are released only at an increased pump pressure by utilizing this pressure these cleaning nozzles. As a result, an intensive scavenging zone is formed which can be switched on and off in a simple manner by means of the pump speed.
  • the DE 2143111 A1 describes a dishwashing machine with a spray arm, which has an adjustment unit with which the direction of rotation of the spray arm can be changed when the circulation pump is briefly off and then turned on again.
  • a dishwashing machine of the type mentioned is proposed with the invention, which is characterized in that the drive nozzles are each equipped with an adjustment that adjusts the spray characteristic of the drive jet of the respective drive nozzle as a function of the pump pressure.
  • the drive nozzles of the dishwasher are according to the invention each equipped with an adjustment. This serves to adjust the spray characteristic of the drive jet as a function of the pump pressure. It can thus be achieved independent of the pump pressure rotational speed of each spray arm, that is, the rotational speed of the spray arm remains unchanged even with increasing pump pressure. As a consequence, the associated increase in volume flow can be used effectively to achieve an improved cleaning result with increased pump pressure, since an increase in the Sprüharmmos für Mikrosystem
  • the speed of the rinsing fluid emerging from the cleaning nozzles is increased, which at the moment of impingement of the rinsing liquor on the ware to be cleaned leads to an improved detachment of soiling, and consequently to an improved cleaning result. It will this improved cleaning result is not minimized by a pressure increased Spülflottenabgabe on the drive nozzles and a concomitant increase in Sprüharmcordiere.
  • the adjustment unit provided according to the invention for each drive nozzle ensures that the spray characteristic of the drive jet of the respective drive nozzle is adjusted to achieve a rotational speed of the spray arm independent of the pump pressure as a function of the pump pressure. The rotational speed of the spray arm thus remains substantially unchanged despite increased pump pressure.
  • the adjustment unit provided according to the invention may be designed in different ways.
  • the adjusting unit has a flow throttle. This ensures that the amount of wash liquor dispensed via the drive nozzles is throttled with increasing pump pressure. As a result, a constant rotational speed of the spray arm is achieved even with increasing pump pressure.
  • the flow restrictor may according to a particular proposal of the invention comprise a membrane, which is arranged upstream of the nozzle outlet in the flow direction of the wash liquor, preferably leaving an annular gap.
  • the annular gap defines the flow opening for the wash liquor.
  • the adjusting device has a closure element for at least partially closing the nozzle outlet.
  • the angle enclosed between the spray arm and the drive jet changes.

  • increased speed of the drive jet as a result of the pressure increase, this does not also result in an increased spray arm rotational speed.
  • the closure element is held under spring bias in the open position. At elevated pressure, the closure element is moved counter to the spring pressure for at least partially closing the nozzle occurrence, wherein the closure element moves corresponding to the applied pressure and thus corresponding to the pressure takes place a corresponding closing of the nozzle outlet.
  • the higher the rinsing pool pressure the further the nozzle outlet is closed and the greater the deflection of the drive jet.

  • the locking member also provides the nozzle side a baffle so that it is not only a change in the flow cross-section at increased rinsing fluid pressure, it is also generated another spray pattern, so that in consequence a constant constant rotational speed of the spray is achieved even at elevated rinsing fluid pressure.
  • the locking member is held in the open position by means of an elastically deformable element, whereby the locking member is always trying to move to its starting position.
