Definitions

  • the invention relates to a household dishwasher with changing loading of at least two spray devices or groups of spray devices, of at least a circulating pump with rinsing liquid to apply to be cleaned Be well supplied.
  • 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.
  • the rinsing liquid conveyed by the circulation pump is added to the spray devices Liquid supply lines led.
  • the in these liquid supply lines during the circulation amount of rinsing liquid usually referred to as the amount of dead water - is not at the point of action during the flow through the liquid supply lines of the goods to be cleaned.
  • This in the liquid supply lines during the circulation amount of rinsing liquid must have a sufficient cleaning effect to achieve, even with household dishwashers with changing loads taken into account by at least two spray devices or groups of spray devices become.
  • the amount of liquid used must therefore be based on the contents of the longest feed path be interpreted, namely, since the circulation pump is usually in the lowest Area of a household dishwasher is arranged, the content of the liquid feed lines to the upper spray device or group of spray devices.
  • the invention is therefore based on the object in a household dishwasher a full use of the filled in in a simple manner To allow amount of liquid.
  • the speed of the circulation pump is adjustable, the speed of the circulation pump when operating the lower spray device or a group of spray devices with a lower spray device to a higher one Speed is regulated as when operating the upper spray device or a group of spray devices with an upper spray device.
  • the delivery rate of the circulation pump increases, i.e. the circulation pump can with the measure according to the invention to the lower spray device or group Pump more spray liquid from spray devices with a lower spray device.
  • the circulation pump can also be the additional amount of rinsing liquid for the content of the liquid supply lines to the upper spray device or group of spray devices for application of the goods to be cleaned.
  • each is operated alternately Spray device or group of spray devices
  • a separate circulation pump is provided, wherein the speed of the circulation pump for operating the lower spray device or a group of spray devices with a lower spray device to a higher one Speed is regulated as the speed of the circulation pump to operate the upper one Spray device or a group of spray devices with an upper spray device.
  • the circulation pump is operated continuously in full load operation. This ensures that the additional amount for the content of the liquid supply lines is also guaranteed to the upper spray device or group of spray devices for Loading of the goods to be cleaned is used.
  • a household dishwasher according to the invention has a circulation pump for loading spray devices with rinsing liquid for the loading of items to be cleaned which are arranged in a rinsing container Good on.
  • the household dishwasher according to the preferred embodiment of the Invention is operated with changing loading of two spray devices, one for which Reversing device is used.
  • the spray equipment is used by the circulation pump conveyed rinsing liquid by means of liquid supply lines.
  • the in these liquid supply lines amount of rinsing liquid during circulation - usually called dead water quantity - is used to achieve a sufficient cleaning effect, also in the inventive household dishwasher according to the preferred embodiment of the invention, i.e. the amount of liquid used is after Contents of the longest loading path designed.
  • the circulation pump is in the lowest area the household dishwasher. Therefore, the amount of flushing liquid for the Contents of the liquid supply lines to the upper spray device, which are in the uppermost area of the Household dishwasher is arranged, additionally filled.
  • the embodiment is the lower spray device directly above the circulation pump arranged.
  • the speed of the circulation pump can be regulated according to the invention, the speed the circulation pump is regulated to a higher speed when the lower spray device is operated is considered to be in operation of the upper sprayer.
  • the circulation pump is used to spray the material to be cleaned constantly operated at full load.
  • a household dishwasher according to the invention according to a further advantageous Embodiment of the invention has two circulation pumps for loading the spray devices on.
  • the household dishwasher according to the further advantageous embodiment the invention is with changing loading of two spray devices, the upper one and the lower spray device, for which purpose each spray device operated alternately a separate circulation pump is provided and what these circulation pumps for Avoidance of the use of expensive and trouble-prone reversing devices, operated alternately.
  • the spatial arrangement of the two spray devices and the Circulation pumps are selected as in the exemplary embodiment described above.
  • the speed of the circulation pump for operating the lower spray device regulates a higher speed than the speed of the circulation pump for operating the upper one Spraying device.
  • the circulation pump operated in each case, especially the circulation pump for loading the lower spray arm during operation constantly operated at full load.
