Definitions

  • the invention relates to a dishwasher, in particular for domestic use, with an electrical heating device for heating the washing liquid and for drying the dishes.
  • the usual dishwashers have a heating rod made of an electric tubular heater in the container holding the dishes.
  • part of the z. B. sprayed from distributor arms washing liquid on the tubular heater, so that it is heated and the tubular heater is cooled.
  • These constructions have the disadvantage that dirt and detergent residues adhere to the surface of the tubular heater and dry up, so that the heat emission from the tubular heater is impaired.
  • the spray jets are also covered by dishes so that the tubular heater overheats locally.
  • the dishes are dried by the radiation from the tubular heater.
  • the drying process is accordingly uneven, ie in the vicinity of the tubular heater or dishes placed in the radiation area are heated more than covered dishes. The uneven heat transfer to the washing liquid and the dishes during the drying process leads to increased energy consumption.
  • the invention is based on the task of proposing a dishwasher in which both the washing liquid and an air stream are heated by means of an electric heating device, with a uniform, energy-saving heat transfer from the heating device to the washing liquid or to the air stream.
  • a dishwasher has in the usual way a housing 1 with generally extendable baskets 2, which serve to hold the dishes 3.
  • a collecting sump 4 is used to collect the outflowing rinsing liquid, which is supplied by a pump 5 via a pipe 6, a lower distributor arm 7 and an upper Ver divider arm 8 is fed.
  • the distributor arms 7 and 8 are attached to a pipe section 9.
  • tubular heating elements 11 are arranged on the tubular piece 6, specifically the tubular heating elements 11 are bent helically around the tubular piece 6. Furthermore, a pipe section 12 is provided which has a larger diameter than the pipe section 6 and which is arranged concentrically to the axis of the pipe section 6 and the helical axis of the tubular heating element 11. An air line 13 is connected to the pipe section 12, so that air sucked in by a blower 14 is driven through the annular channel formed by the pipe 6 and the pipe 12 during the drying process.
  • the arrangement 7, 8, 9 is rotatably mounted in the upper ends of the pipe sections 6 and 12.
  • the lower distributor arm 7 is divided in two by means of a partition 15.
  • the lower region of the distributor arm 7 communicates with the annular space between the pipe sections 6 and 12, so that the air sucked in by the blower 14 and passing over the tubular heating element 11 is blown out of the nozzles 16 into the interior of the container 1.
  • the upper part of the distributor arm 7 and the interior of the distributor arm 8 are connected to the interior of the pipe section 6, so that the washing liquid driven by the pump 5 is sprayed onto the dishes via spray nozzles 17.
  • the drive takes place in a known manner by the recoil of the media emerging from the correspondingly inclined nozzles 16 and 17 streams, ie the detergent liquid flow or the heated air flow.
  • the flow tube 6 can also be formed by a die-cast part that has helical grooves on its outside for receiving heating coils and insulating material.
