Definitions

  • the invention relates to a dishwasher according to the Preamble of claim 1.
  • the dishwasher is in a wash cabinet two spray devices at different height levels arranged as a rotatable spray arms are trained and located in crockery baskets Spray washware from below. For this purpose are on the spray devices (first) spray nozzles for the discharge of Flush liquid provided. Because the number of spray nozzles the items to be washed are sprayed independently from the respective loading condition, i.e. independently the amount and / or the distribution of the items to be cleaned Wash items. However, one is requested to the Loaded spraying adapted to the load.
  • the invention is based on this prior art the task of providing a dishwasher, which an improved cleaning of the dishes, in particular with regard to the loading condition.
  • a core of the invention is that an additional or several second spray nozzles on the at least one Spray device are provided, in particular by means of are adjustable at least one actuator. Based The adjustable second spray nozzle can control the amount of the escaping flushing liquid optimally to the amount of Washware can be adjusted.
  • the adjustable second spray nozzle can control the amount of the escaping flushing liquid optimally to the amount of Washware can be adjusted.
  • the second Spray nozzles on the spray devices or on the Spray arms become certain wash zones in the wash cabinet of the dishwasher formed in which the dishes are more intense is sprayed with rinsing liquid. For example edge rinsing zones are formed, in which if necessary the washware on the edge more intensively Flushing liquid is sprayed, so that additionally the distribution of the wash ware can be taken into account.
  • the adjustable second spray nozzle is the user in able, depending on the loading condition, i.e. to the crowd and / or more intensive adapted to the distribution of the wash ware To create rinsing zones, thereby cleaning the Washware is significantly improved.
  • Each second spray nozzle is advantageously one Actuator assigned so that the second spray nozzles are individually adjustable.
  • the corresponding rinsing zones can be activated individually so that you get a high level of flexibility becomes.
  • the actuating elements are preferably movable on the or arranged on the spray devices and in at least two positions can be brought so that the rinsing liquid escapes from the second spray nozzles at least partially is permitted or prevented.
  • the second spray nozzle can be opened easy to open or close.
  • the flushing fluid pressure be varied so that ensures optimally adapted cleaning of the wash ware is.
  • the actuating elements advantageously each comprise an approximately platelet-shaped cover that is slidable and / or rotatably arranged on or on the spray devices is and preferably in at least one position can be locked. Based on this constructive measure a simple and safe setting of the enable second spray nozzles.
  • this actuator is flat designed and contains several breakthroughs. Is this Actuating element displaceable and / or rotatable on the Spray device or arranged on the second spray nozzles, so change with the movement of one actuator several or all second spray nozzles at the same time. It is through appropriate constructive measures possible to design the actuator so that the adjustable spray nozzles either fully open, partially are open or completely closed so that the Open and close transition between spray nozzles continuously can be done.
  • Another spray device can be designed so that all spray nozzles provided by a movable actuator are adjustable, this one actuator has one or more breakthroughs, so that as a result a rotation or displacement of the actuating element These can be adjusted together via the spray nozzles and thus the setting of the spray nozzles too stepless between complete passage and closure can be done.
  • FIG 2 to 2b each show an enlarged representation of an actuating element of FIG 1 in different positions relative to a second spray nozzle.
  • FIG 1 is a schematic representation of a testing device 1 shows a dishwasher in top view, which are mounted rotatably about an axis of rotation D, comprises two-wing spray arm 2. At the top of the Spray arms 2, first spray nozzles 3 are distributed, which are used to spray dishes. The wash ware is in a crockery basket located above the spray arm 2 (not shown) arranged. In addition, there are 2 second spray nozzles 4 are provided, each by means of a Actuator 5 are adjustable.
  • the actuators 5 are made of a non-corrodible material, expediently made of plastic.
  • Embodiment according to FIG 1 are four second Spray nozzles 4 over the radial length L of the spray arm 2 in such a way distributed that over the length L overall formed four radially spaced rinse zones in which the dishes are sprayed more intensively if necessary can be.
  • the actuating elements 5 are used for opening or closing the second spray nozzle 4 so that the outlet the rinsing liquid from the second spray nozzles 4 allowed or is prevented and accordingly based on the of the second spray nozzles 4 active or are inactive.
  • at the bottom of the Spray arm 2 provided one or more second spray nozzles 4 be, which are also adjustable by means of actuators 5 are. This measure is particularly useful for spray arms 2 advantageous in an upper level in the wash cabinet the dishwasher are arranged.
  • the actuating element 5 comprises an approximately plate-shaped one Cover, which is guided on the spray arm 2 is, for example in a recess 7 of the Spray arm 2.
  • the actuating element 5 has a projection 6 to facilitate manual operation.
  • the actuating element 5 can be designed such that it using the corresponding selection buttons or certain wash programs is controllable.
  • the actuating element 5 is in a first position 8 relative to the second Spray nozzle 4 positioned that the rinsing liquid through the second spray nozzle 4 can pass completely through.
  • the actuator 5 By moving the actuator 5 in the direction of Arrow A to the second spray nozzle 4 reaches the actuating element 5 in a second position 9 (FIG 2a), in the it partially covers the second spray nozzle 4, so that only a partial leakage of rinsing liquid enables is.
  • By reducing the cross section of the second spray nozzle 4 is an increase in pressure of the rinsing liquid reached.
  • the actuator 5 continue in the direction of arrow A into a third position 10 pushed, as shown in FIG 2b is.
  • this third position 10 the second spray nozzle 4 completely covered by the actuating element 5 or closed.
  • the flushing fluid pressure can be varied. Are all, for example second spray nozzles 4 completely closed (third Position 10), the pressure from the first increases Spray nozzles 3 escaping rinsing liquid to a maximum.
  • second spray nozzles 4 With the second spray nozzles 4 partially open (second position 9) can both an increased pressure and a achieve an increased amount of escaping flushing liquid. For example, are the second spray nozzles completely open? (first position 8), the maximum quantity appears Flushing liquid at comparatively lower pressure, so that both a gentle and an intensive cleaning of the wash ware is guaranteed.
  • the actuating elements 5 can additionally latch means (not shown), which with corresponding locking means engage on the spray arm 2 so that the actuating elements 5 in the three positions described above 8, 9 and 10 can be locked.
  • Actuators 5 designed to be rotatable or pivotable Actuators can be provided by turning or Swing the second spray nozzles 4 open at least partially or close.
  • every second spray nozzle 4 each has a movable actuating element 5 is assigned, are the second spray nozzles 4 individually or independently adjustable.
  • the User thus has a variety of variation options available to according to quantity, distribution and / or Degree of soiling of the wash ware the spraying of the wash ware to be flexible.
  • Using the adjustable second Spray nozzles 4 can be the amount, the direction or the Rinsing zones and / or the pressure of the escaping rinsing liquid adapt optimally to the loading condition.
