Definitions

  • Dishwasher spraying devices consist of a spray arm, which is rotatably attached to the water supply pipe, the so-called connecting pipe.
  • the water jet is brought into the spray arm via the connecting pipe at the end of which the water inlet.
  • Distributed over the spray arm are outlet nozzles through which the water or the cleaning liquid is sprayed onto the dishes located in the crockery basket.
  • the spray arm is set in rotary motion. This rotational movement of the spray arm about the axis of the water inlet will usually be via one or more drive nozzles which are at the periphery of the spray arm and produce a water jet substantially tangential to the direction of rotation of the spray arm.
  • the drive nozzles provided at the periphery are disadvantageous, since the water issuing from them is essentially needed only for driving the spray arm and is not available for cleaning the dishes.
  • a spraying device having the features of the preamble of the independent claim is known from the document EP-A-0 321 025.
  • the object of the present invention is to enable a drive for a spray arm, so that the conventional drive nozzles can be completely or at least partially dispensed with and almost all the water can be used for cleaning.
  • a dishwasher spraying device comprising a spray arm rotatably mounted around water inlet, the water inlet having fixed turbine blades.
  • An advantageous embodiment of the invention is that in the spray arm vanes (LS) are attached.Damit the efficiency with respect to the angular momentum can be further increased.
  • the spray arm can still have drive nozzles which, however, can advantageously be dimensioned smaller than heretofore.
  • FIG. 1 shows a section through a spray device of a dishwasher, which consists of the connecting pipe VR and the spray arm SA.
  • the spray arm SA is rotatably supported by a plain bearing GL around the water inlet WE, which is generally angled perpendicularly to the connecting pipe VR.
  • Water is pumped in the direction of the arrow into the spray arm SA via the connecting pipe VR at whose end the water inlet WE is located.
  • Distributed over the spray arm SA are cleaning nozzles RD by means of which the water or the cleaning liquid is sprayed onto the dishes located in the dish rack.
  • the rotational movement of the spray arm about the axis A of the water inlet nozzle WE is conventionally realized via one or more drive nozzles AD, which are located at the periphery of the spray arm SA and produce a water jet counter to the direction of rotation of the spray arm SA.
  • the fixed blades of the water inlet WE are designated with turbine blades TS and with guide blades LS the blades which rotate with respect to the turbine blades TS and are located in the spray arm SA.
  • the turbine blades TS are here arc-shaped, but may also have a different shape.
  • the person skilled in the art will receive suggestions from turbine technology for designing the blade shapes for optimized operation. This also applies to the guide vanes LS. It is only important that the blades LS, TS are shaped so that the water flowing into the spray arm generates a torque on the spray arm.
  • FIG 2 In the illustration of FIG 2 is indicated with curved arrows, such as the cleaning liquid between the turbine blades TS flows through it. Since the turbine blades TS are stationary, the water is pressed against the guide vanes LS located in the spray arm SA, so that a torque is generated in the direction of rotation DR indicated by the arrow.
  • the vanes LS are not necessarily provided, since a torque can also be generated via the side walls of the spray arm. But they improve the angular momentum accordingly. Of course, it is also possible to use straight guide vanes or differently shaped guide vanes LS instead of the curved guide blade LS.
  • additional drive nozzles AD can be additionally provided, which, however, can generally be dimensioned much smaller than is the case with conventional spray devices. Depending on the design of the spraying device and the spray arm, it may be possible to completely dispense with the drive nozzles.
