Definitions

  • the invention relates to a household dishwasher with changing loading of at least two spray devices or groups of spray devices that are operated by one Circulation pump supplied with rinsing liquid to act on the items to be cleaned become.
  • Household dishwashers with alternating operation of the spray levels have long been known e.g. from DE-OS 24 28 991.
  • the at least two spray devices simultaneously with that of a circulation pump fed liquid.
  • DE-OS 24 28 991 is used to achieve the same or better cleaning result as with the above-mentioned standard household dishwashers
  • Spraying device alternately in succession with the one conveyed by a circulation pump Liquid is fed, so that the full pressure of the circulation pump is only at one spray device to work and a lower amount of liquid and less energy to Circulation and also needed to heat the circulated liquid.
  • Reversing devices from a circulating pump are used.
  • the invention is therefore based on the object in a household dishwasher of the type mentioned at the outset when changing from a spray device or a group from spray devices to a further spray device or group of spray devices to avoid increased noise in a simple manner.
  • This object is achieved in that the speed of the circulation pump is controllable, during the change from a spray device or a group from spray devices to a further spray device or group of spray devices the speed of the circulation pump is reduced.
  • a household dishwasher has a washing container in which Good to be cleaned, e.g. dirty dishes and cutlery, usually in baskets is filled.
  • Good to be cleaned e.g. dirty dishes and cutlery
  • This rinsing liquid Usually called the rinsing liquor, is added to the liquid supply lines by means of a circulation pump the spray devices promoted.
  • alternate loading is carried out of at least two spray devices or groups of spray devices - of Spray Levels - performed by the circulation pump, so the full pressure of the circulation pump only to act on a spray device and a smaller amount of rinsing liquid and less energy to circulate and also to heat the circulated Need rinsing liquid.
  • alternately Feeding the spraying devices from a circulating pump becomes reversing devices used.
  • EP-OS 05 47 011 it is known, for example, by means of a hydraulically operated flap valve arranged between liquid supply lines to the spraying devices alternately open one of the liquid supply lines and at the same time the other liquid supply lines close.
  • EP-OS 02 37 994 it is also known, for example, by means of a ball in the pressure port of the circulation pump, which if the Operation of the circulation pump changes the position, alternately one of the liquid supply lines to open and close the other at the same time.
  • EP-PS 05 85 905 by means of a motor-driven, rotating horizontal Washer with holes to one or more entrances to liquid supply lines open and close others
  • the speed of the circulation pump can be regulated.
  • the speed of the circulation pump during the change from a spray device or a group of spray devices reduced to a further spray device or group of spray devices and thus counteracted a brief ramp-up of the speed of the circulation pump.
