Definitions

  • the invention relates to a dishwasher with a distribution device for distributing rinsing liquid in the interior of the dishwasher.
  • rinsing liquid distributors in the form of rotating spray vanes are arranged in the interior both below the lower rack and below the upper rack, distributing the rinsing liquid from a plurality of spray nozzles during rotation within the washing compartment.
  • the rotation of the spray vanes is achieved by the recoil of the distributed rinse liquid due to the special orientation of the spray nozzles.
  • a distribution device has at least one spray rod or spray wing rotatable about its longitudinal axis.
  • the spray bar or spray wing is mounted on one side or at both ends or at an intermediate point along its longitudinal extent. Due to the rotatability of the spray bar about its longitudinal axis, the rinsing liquid sprayed out through a nozzle is sprayed into a circular plane during the rotation. With a very small space requirement for carrying out the rotational movement of the spray bar, a particularly wide-spread distribution of the rinsing liquid is achieved.
  • One or more of such spray bars may be provided, for example, in a locally limited interior area of the dishwasher in order to uniformly apply washing liquid stored in the washing compartment, for example in the direction of a separate cutlery tray.
  • a conventional overhead shower or a conventional distribution device with rotating spray wings a uniform application, for example in the corners of the dishwasher, not readily ensured.
  • a storage of a spray bar on a Spül folkkeitszulauf which supplies the rinsing liquid to be distributed in the interior of the spray bar.
  • the rinsing fluid inlet is particularly advantageously arranged at one end of the spray bar, but can also be made at any point along the extension of the spray bar.
  • the Spül thoroughlykeitszulauf is centered on the spray bar, the feed serves as storage for both halves of the spray bar.
  • a sealing device between Spül thoroughlykeitszulauf and spray bar reduces the Loss of rinsing liquid at the transition between non-rotatable and rotating parts.
  • At least two spraying rods are advantageously arranged at a distance from one another in a horizontal plane.
  • the horizontally extending spray bars may be vertically offset from each other, for example, when the bottom of a dish rack is not flat and the arrangement of the spray bars is provided staggered.
  • Such optimal space utilization is not possible with a conventional, rotating spray wing, since in the horizontal plane it always requires the space required for a circular area with the corresponding overall height of the spray wing for full rotation.
  • at least one spray bar may be provided in a corner of the washing compartment interior, with which the wash ware is subjected to rinsing fluid from the corner.
  • At least one spray arm rotatable about its longitudinal axis can also be provided on a rotating rinsing fluid feed, as used, for example, in a conventional spray arm with spray vanes.
  • a Spül thoroughlykeitsbeetzung is provided in all directions in space during rotation both about the vertical axis and about the longitudinal axis.
  • Fig. 1 shows schematically a horizontal cross section through a dishwasher interior just below the inner ceiling, wherein 1 denotes a dishwasher inner wall and 2a-2d spray bars, which are formed as a hollow profile and extend horizontally in the dishwasher interior.
  • the spray bars 2a-2c are arranged in a height plane and apply during their rotation the dishes stored in an upper dish rack with rinsing liquid.
  • the spray bar 2c is shortened compared to the spray bars 2a and 2b, since in the front region of the dishwasher interior a cutlery basket 12 is arranged, which would partially overlap with the extended design of the spray bar 2c with this.
  • the silverware stored in the cutlery basket 12 is supplied with rinsing liquid by the spray bar 2d, which has a reduced size compared with the spray bars 2a-2c.
  • the spray bars 2a-2d are mounted at both ends on the one hand on an outer bearing 3 and on the other hand on an angle feed 4 (see detail view in Fig. 2B).
  • the Winkelzu effect 4 lead the spray bars 2a-2d flushing liquid from the ceiling side, so that the Winkelzu instrument 4 also include a fluid passage through the dishwasher inside ceiling.
  • Fig. 2A shows a section through a spray bar 2 transverse to the longitudinal extent.
  • the rinsing liquid supplied through the angle feed 4 is distributed in the interior of the spray bar 2 and is discharged through spray nozzles 11 or openings arranged on the outer circumference of the spray bar.
  • a spray nozzle cluster is distributed diagonally opposite to the outer circumference with respect to the axis of rotation, so that in total by the spraying of the flushing liquid the recoil exerts a torque on the spray bar 2 which sets the rotatably mounted spray bar 2 in rotation.
  • the distribution direction of the washing liquid is indicated by the straight arrows.
  • Fig. 2B shows schematically a longitudinal cross-section through a spray bar 2 and its associated angular feed.
  • the rinsing liquid is introduced through a ceiling passage 10 in the angle feed 4, where the rinsing liquid is deflected and introduced into the hollow spray bar 2.
  • a metal pin 7 serves as a shaft for supporting the spray bar 2, wherein the one end of the metal pin 7 is rotatably mounted in an inner bearing 8 within the angle feed 4.
  • the other end of the metal pin 7 is rotationally rigidly connected to the spray bar 2, wherein radially extending webs 9 between the metal pin 7 and the outer wall of the spray bar 2 on the one hand stabilize the metal pin and on the other hand provide sufficient opening cross section for introducing the rinsing liquid in the spray bar.
  • the webs 9 may be formed helical or turbine blade-like, so that in addition to the arrangement of the nozzle of Fig. 2A is rotated by passing the rinsing liquid from the angle feed 4 in the spray bar 2 of the spray bar.
  • FIG. 3 shows a further field of application of a spray bar 17 which can be rotated about its longitudinal axis.
  • a spray device with a distributor 19 and two spray arms 16 rigidly connected thereto is designed with spray wings in relation to the storage and the inlet in accordance with a conventional spray arm.
  • the two spray bars 17 are provided on the manifold 19, which are rotatably mounted on a bearing 18 on the distributor 19.
  • both are Spray bars 17 connected to a metal pin which, as in Fig.
  • a bearing or a double bearing for free rotation of the extending between the spray bars 17 metal pin is provided .
  • the orifices for discharging the rinsing liquid are aligned so as to effect rotation of the sprayer 15 as in a conventional arrangement, while the nozzles are arranged on the spray bars 17, as shown in Fig. 2A, for example.
  • the entire assembly 15 rotates about an axis perpendicular to the plane of the drawing, and in addition the spray bars 17 rotate about their own longitudinal axis in the plane of the drawing.
