Definitions

  • the invention relates to a spray device for an automatic dishwasher according to the preamble of Claim 1 and a dishwasher with a such spray device.
  • Rotatable spray devices for automatic dishwashers are known in a variety of designs.
  • the German utility model DE 78 27 011 U1 describes e.g. a spray device with a spray arm, on which several, knob-like, rotatable spray heads are arranged are.
  • the spray heads have fine spray openings for water penetration and are affected by water pressure rotated around their axes of rotation.
  • the object of the invention is such Develop spraying device so that it is as possible is easy to manufacture and still a good one Has spray effect. This task is accomplished by the spray device fulfilled according to claim 1.
  • the spray head is on a suitable Water supply provided a holding arm, which the spray head holds on the tub side, whereby under "tub side" the opposite of the water supply, the inside of the Understand vat facing the spray head is.
  • the holding arm is used to press the spray head against the Water flow, or the water pressure prevailing in it, to keep.
  • the holding arm is arranged so that it the spray opening (s) of the spray head as it rotates periodically covers at least partially so that the water jet is interrupted. This leads to a pulsed Water leakage, which is the kinetic energy of the water jet and thus improves the cleaning effect.
  • the holding arm can block the spray head thanks to the above crockery and cutlery items or at least partially prevent and the risk of Reduce clogging of the nozzles due to nozzle particles.
  • the holding arm thus takes over a mechanical one Function when holding the spray arm, at the same time but also a hydraulic function in the periodic Interrupting the spray emerging from the spray opening Water jet.
  • the spray head can either be stationary or open a rotating spray arm can be placed in the tub.
  • FIG. 1 A preferred embodiment of an automatic dishwasher with the spray head according to the invention is in Fig. 1 shown.
  • the dishwasher has one Housing 1, in which a tub 2 for receiving the Washware is arranged.
  • the tub 2 is through a door 3 closed and can in a known manner several crockery baskets Record 4a, 4b.
  • a lower spray arm 5 is on the floor 6 of the tub 2 arranged and an upper spray arm 7 on the upper basket 4a. Both spray arms 5, 7 are in known manner rotatable. On the top wall 8 of the tub a water guide 9 with spray head 10 is also arranged. The same type of spray heads 10 can also be used on the Spray arms 5, 7 may be provided.
  • FIG. 2-6 A preferred embodiment of the spray head 10 is shown in Figs. 2-6.
  • the spray head 10 will formed by a lid-shaped rotating body 11, the present embodiment four spray openings 12a, 12b, 13a, 13b for the water outlet (Fig. 4).
  • the rotating body 11 is rotatable about an axis of rotation 14 stored. It sits like a lid a nozzle 15 of the water guide 9. Grab it Water guide 9 (or nozzle 15) and rotating body 11 so into each other so that they form a radial guide that Movements of the rotating body 11 perpendicular to the axis of rotation 14 prevented.
  • a holding arm 16 is provided for axial fixation of the rotating body 11 .
  • the holding arm 16 has in the present embodiment has a bracket 17, which itself extends across the rotating body 11 and at both ends is attached to a frame 18.
  • the frame 18 encompasses the outside of the water guide 9 and is in a snap lock attached to two lugs 19 of the water guide 9.
  • the tub side is on the rotating body 11 in the area an increase 20 is provided for the axis of rotation 14 (FIG. 3), which ensures low-friction contact with the bracket 17.
  • the Spray arms 5, 7 of the dishwasher with one or several spray heads 10 according to FIGS. 2-6 can be provided (see Fig. 1), in which case the spray arms Form the respective water supply.
  • the spray arms Preferably everyone Spray arm 5, 7 provided with several spray heads, each different distances from the respective swivel axis of the Have spray arms so that the water is as extensive as possible is distributed on the wash ware.
  • the present invention can be of many different types Points can be changed.
  • a simple bracket 17 with two ends on Frame 18 is attached, an angled arm is provided be only on one side on the frame 18 or on the water guide 9 is arranged.
  • a bracket is also conceivable to be used with three or more angled arms, whereby an outer end of each arm is attached to the frame 18 and the inner ends of the arms are in the area of the Hit axis of rotation 14.
  • the Water jet from each spray opening 12a, 12b, 13a, 13b interrupted only once or more than twice per rotation.
  • Spray openings 12a, 12b, 13a, 13b can also have a different number on the rotating body Spray openings may be provided.
  • the Spray openings are at least partially different from one another designed so that there is better water distribution results.
  • the spray openings are preferably each arranged symmetrically about the axis of rotation 14 that the radial bearing forces generated by the water deflection cancel each other out.
