Definitions

  • the invention relates to a dishwasher with a rinsing container with a rotating spray device which has a support arm rotating about a first substantially vertical axis and a distance from the first vertical axis on the support arm about a second, also substantially vertical axis comprising rotating and at least one arm having spray arm which sprays cleaning liquid onto dishes to be cleaned via nozzles and is drivable together with the support arm by the recoil of the pressurized cleaning liquid.
  • a spray device is arranged with at least one, about a substantially vertical axis rotatable spray arm. This in turn is rotatably arranged about a further, also substantially vertical axis. This axis passes essentially through the center of the dishwasher.
  • the spray arm undergoes an epicycloidal movement when pressurized water first flows through the axis in the center of the dishwasher through a support arm rotatably supporting the spray arm and then via a turbine transmission mounted on the axis of the spray arm in the support arm due to the recoil of the water Spray arm in put a rotary motion.
  • the spray arm extends from its axis of rotation over a radial length which is substantially equal to a quarter of the shortest inner side of the washing container.
  • the distance of the two axes of rotation from one another essentially corresponds to the radial length of the spray arm.
  • the support arm preferably extends in this dishwasher substantially between the axis of rotation of the spray arm and the axis of rotation of the support arm.
  • a pressurized water distribution circuit is provided which operates at a lower or higher pressure depending on the intensity provided in accordance with the rinse program.
  • this object is achieved in a dishwasher of the type mentioned above in that the nozzles are arranged substantially at the outer end of the at least one partial arm.
  • the invention provides a dishwasher in which all areas of the surfaces of the items to be washed are achieved by the cleaning liquid, so that a good cleaning with high cleaning intensity is achieved.
  • An advantage is a dishwasher in which the nozzles too 90% are arranged in the outer third of the at least one partial arm.
  • openings of the nozzles have at least one direction component in the tangential direction of the spray arm, based on the circle plane spanned by the latter during its movement about the axis of rotation.
  • the spray arm comprises two with respect to its axis of rotation symmetrically opposing partial arms, on the outer peripheries of the nozzles are arranged distributed. By the two arms a complete spraying of the items to be cleaned is guaranteed.
  • the nozzles are each oriented in different directions, so that the cleaning liquid or the water impinges on the dishes from different angles.
  • the nozzles can be aligned in the vertical direction, in or against the drive direction, inwards or outwards or obliquely to the longitudinal axis of the arms of the spray arm.
  • at least one of the nozzles is arranged at least partially inclined with respect to the vertical axis of the spray arm or lying in the plane of rotation of the spray arm.
  • the support arm extends substantially over a length which is determined by the distance between the two axes of rotation.
  • the short length of the support arm pressure losses of the water, which would be lost by the drive and the filling of a double as long arm, saved. This is more cleaning water within the water cycle for cleaning the dishes available, so that in particular a sufficiently high pressure to generate the rotational movement of the spray arm is maintained.
  • the spray arm has approximately the length of the support arm, which may be about one-quarter of the shorter side length of the washing container or even shorter. Depending on the orientation of the spray nozzles, the length of the spray arm but also be even lower.
  • a very compact spraying device is provided, which ensures optimum wetting of the ware due to the epicycloidal movement of the spray arm.
  • the spraying device comprises in the ceiling and / or in the bottom region of the washing compartment a rotary device, each consisting of a support arm and a spray arm, which is connected to a circulating system for the cleaning fluid.
  • a spray device 1 integrated in a cycle for circulating a cleaning liquid ( Fig. 1 ) is mounted either under the ceiling or above the bottom of a washing container 2 in a dishwasher.
  • the spray device 1 comprises a support arm 4, which is rotatable about a rotation axis 3 arranged essentially in the middle of the washing container 2 and whose length is less than a quarter of the smaller side length of the washing container 2.
  • a spray arm 6 is rotatably arranged about a further axis of rotation 5.
  • cleaning liquid is supplied under pressure to the support arm 4 via a first rotary leadthrough in the area of the rotation axis 3, which continues to flow into the spray arm 6 through the interior of the support arm 4 via a second rotary leadthrough in the region of the rotation axis 5.
  • the cleaning liquid Due to the pressure under which the cleaning liquid stands, it is sprayed out of nozzles 7 at the outer ends of the spray arm 6. Since at least some of the nozzles 7 have an opening from which the cleaning liquid flows out in such a way that it has a directional component in the tangential direction with respect to the circular plane formed by the spray arm 6, the spray arm 6 rotates in a circular motion about the axis of rotation 5. Simultaneously is due to the recoil and the support arm 4 is set in motion, so that this is a circular movement corresponding to a circular line A, which reflects the movement of the outermost radial point of the support arm 4.
  • the spray arm 6 executes an epicycloidal movement on a line of movement B, which reflects the movement of the outer periphery of the spray arm 6.
  • the dishes in the washing container 2 is sprayed under a variety of different angular positions and is thereby completely wetted.
  • the spray arm 6 has two with respect to the axis of rotation 5 symmetrical part arms 61 and 62, at the outer ends of each of the spray nozzles 7 are arranged.
  • the spray nozzles 7 ( Fig. 2 . 3 ) preferably have different opening angles with respect to the plane of the spray arm 6 and with respect to the axis of rotation 5, so that the cleaning liquid flows out of them in different directions C, D, E, F and sprays different areas of the dishes within the washing container 2 in each position of the spray arm 6 become.
