Definitions

  • the invention relates to a dishwasher, in particular household dishwasher, with a rinsing container for receiving items to be washed, and at least one operating device for influencing and / or detecting the biological and / or chemical and / or physical properties of the cleaning liquid, in particular pH, temperature, Surface tension or hardness, in and / or at the washing container, wherein in the at least one operating device at least one spraying device for spraying cleaning liquid is integrated on the dishes, and wherein the at least one spraying device is a spray nozzle.
  • the publication DE 84 34 858.5 U1 shows a washing machine with an interior in which are provided at the top of an outwardly curved end plate embedded therein spray nozzles.
  • a dishwasher wherein auxiliary nozzles are arranged on the rear wall in the washing compartment of the dishwasher.
  • the publication DE 1 628 596 A shows a dishwasher, in which a nozzle for generating a fan-shaped jet of water is provided in the upper region of the washing compartment adjacent to the ceiling.
  • a dishwashing machine which comprises a trough which is accessible from above via an opening, wherein the opening can be covered by a lid.
  • the document DE 197 08 805 A1 shows a dishwasher with obliquely arranged dish rack, wherein for cleaning rinsing nozzles are arranged below and above the basket.
  • the upper rinsing nozzles are mounted in the ceiling of the washing compartment and the lower rinsing nozzles are formed on a cassette-type washing distributor on the underside of the washing compartment.
  • a dishwasher which has at the top in the washing compartment a spray nozzle with a cylindrical main body and corresponding outlet openings in the main body.
  • the publication DE 694 09 198 T2 discloses a dishwasher whose sink is open at the top, being held over the opening by an operator dishes in the washing compartment. The cleaning of the dishes via arranged in the region of the opening nozzles, which are integrated in the wall of the washing compartment.
  • Dishwashers known from the prior art for cleaning liquid-based cleaning have the disadvantage that the spray devices used are integrated as separate components in the washing compartment. This requires a lot of effort in the production of the dishwasher, as for example in the walls of the washing compartment separate openings for attachment of the nozzles and separate lines must be provided for cleaning liquid supply of spray.
  • EP 1 554 970 A1 discloses a dishwasher according to the preamble of independent claim 1.
  • the object of the invention is therefore to provide a dishwasher, which is simple to build and manufacture.
  • the operating device is installed in an opening or recess of a wall of the washing container.
  • the invention is based on the finding that spraying devices in the washing compartment do not necessarily have to be formed separately from already existing operating components of the dishwasher.
  • those operating devices for which an opening is provided in the wall or in the bottom or in the lid of the washing compartment can also assume the function of a spraying device, since an access from the outside into the washing compartment is created via the already existing opening, via the cleaning liquid can be supplied for spraying in the washing compartment.
  • the essence of the invention thus consists in that operating devices known per se, which do not primarily have the function of a spraying device, are equipped with a spraying device. As a result, the manufacturing costs for the dishwasher are reduced, since no separate openings and passages for the sprayers must be provided in the walls of the washing compartment.
  • the at least one operating device is a device for supplying cleaning fluid and / or other addition means into the washing compartment or a sensor, for. B. for temperature and / or turbidity of the wash liquor and / or loading state and / or moisture.
  • a sensor for. B. for temperature and / or turbidity of the wash liquor and / or loading state and / or moisture.
  • the spraying device is integrated in the water and / or Spülflotteneinlaufsystem the dishwasher. Additionally or alternatively, however, it is also possible for the spray device to be integrated in the feed device for feeding in detergent and / or rinse aid and / or softener.
  • operating devices which are arranged in an upper region in the washing compartment, in particular in the upper half, preferably in the upper third and particularly preferably in the upper quarter, are preferably used to integrate the spraying devices.
  • This allows the Spray device to take over the function of a shower head, which is particularly effectively prevents back soiling of soiled items during cleaning.
  • the spraying device is arranged in the upper region of the operating device. In this way, the previously described, advantageous roof shower function of the spray can be achieved.
  • a plurality of spraying devices are provided, which are arranged in the same plane and / or in a plurality of staggered planes, the planes preferably extending in the horizontal direction. This ensures a particularly good cleaning in different areas of the washing compartment. In particular, it is also possible to specifically purify certain objects which are arranged in a predetermined plane in the washing compartment.
  • the cleaning is effected mainly by a spray arm, which is arranged for example in the lower region of the washing compartment. Nevertheless, it is also possible to use only such spraying devices in a dishwashing machine or optionally to use additional other spraying devices which are not designed as a spraying arm.
  • the spray nozzle according to the invention comprises a nozzle body which is held in a nozzle holder, wherein the nozzle holder is connected to a cleaning liquid supply system.
  • the nozzle body is fastened here, for example, via a bayonet lock in the nozzle holder.
  • the nozzle body preferably has fan-like arranged cleaning liquid outlet openings.
  • the dishwasher is a so-called drawer dishwasher.
  • the washing container consists of an upwardly open container, d. H. "Drawer" with a bottom and a partition with a front wall, a rear wall and two side walls.
  • the upwardly open container serves to receive soiled items or items to be washed.
  • the upwardly open container is movable. In a pushed out, i. withdrawn position is the upwardly open container substantially outside the housing of the dishwasher, so that the user can load the dishes in the open-topped container and taken out of it.
  • the container In an inserted position, the container, which is open at the top, is located in the housing of the dishwasher and is sealed watertight by a lid in order to be able to carry out a rinsing process.
  • the at least one operating device is arranged in the upper region of the wall, in particular in the upper half of the wall, preferably in the upper third. Since this operating device has a spraying device, this ensures a spraying of the soiled articles from above, i. It is a roof shower function realized without the sprayer must be integrated in the lid. This arrangement is to be preferred in dishwashers in a drawer shape, since the arrangement of the spray in the lid is structurally difficult to implement.
