Definitions

  • the invention relates to a valve in a water outlet a household appliance, in particular a dishwasher, and a tax process for this.
  • the object of the invention is therefore to reduce the water consumption Home appliances to decrease even further.
  • the valve is mechanical or electromagnetic switchable. E.g. through an electromagnetic valve a control device of the household appliance is controlled, so through the program sequence control, preferably the valve only controlled and opened when in the water outlet pipe actually only relatively clean Washing liquid from a previous rinse aid or Wash cycle is available. This ensures that no contaminated liquid in the Dishwasher came back.
  • a position of a Closing element of the household appliance detects, preferably the Flap a washing drum of the washing machine or the door a dishwasher, after pressing the Closing element the valve is controlled.
  • a position of a Closing element of the household appliance detects, preferably the Flap a washing drum of the washing machine or the door a dishwasher, after pressing the Closing element the valve is controlled.
  • the valve is immediate connected to the closing element.
  • the closing element For example, is opened by opening the Door an electrical contact is interrupted or established, which puts the valve in the open position so that the Liquid can flow back out of the water outlet pipe.
  • the valve can also be mechanically e.g. by means of a Lever mechanism with the closing element, e.g. the door of the Dishwasher, be coupled so that the valve is opened. By closing the dishwasher door the valve is closed again. So that one inexpensive arrangement for closing and opening the valve realize.
  • the liquid from the drain or outlet line after the choice of the next rinsing or washing program can only be retrieved, if the program below is a basic wash or Includes pre-rinse.
  • the next program is just a Rinse aid is selected, so it is prevented that already used rinse aid is used again.
  • Fig. 1 shows schematically the arrangement of a controllable Check valve in the drain line one Dishwasher.
  • a pump 1 sucks over a Line 2 rinsing liquid from the not shown Dishwasher sump of a dishwasher.
  • the pumped out Flushing liquid is the controllable via a line 3 Check valve 4 supplied, from which the liquid in the Drain line 5 occurs. From the drain line then the pumped rinsing liquid gets into the Sewage system of a building.
  • the check valve can be operated by an electromagnet 6 Open 4 so that the drain line in it flushing liquid through the check valve, the Line 3 and the pump 1 in line 2 and out of this can flow back into the dishwasher sump.
  • the Electromagnet 6 is controlled by a program sequence control 7 controlled.
