Definitions

  • the invention relates to a method for operating a dishwasher in the is cleaned with a cleaning liquid.
  • a Dishwasher using such a method is known from document DE 1 503 853.
  • This cleaning liquid is usually by means of a circulation pump, the z. B. can be designed as a centrifugal pump, from a constantly refilling Storage container conveyed via liquid feed lines to spray devices, by means of which the liquid is applied to the items to be cleaned.
  • a sufficient cleaning result is achieved when the Good to be cleaned by the amount of chemical additives that the cleaning liquid can be added, but mainly by a sufficient Duration of exposure to the goods to be cleaned and the duration of the time mechanical removal of dirt on the goods to be cleaned achieved. This means, in addition to what is necessary for conveying the cleaning liquid Energy expenditure a long duration of the cleaning program.
  • the liquid With conventional pumping methods, e.g. B. with ordinary pumps, the liquid must be below inflow own hydrostatic pressure from a reservoir into the pump.
  • the active, moving part of the pump in the case of the centrifugal pump the impeller, generates one Vacuum and sucks the liquid into the pump.
  • This negative pressure is caused by the Limited supply of the liquid. If the hydrostatic pressure on the suction side is not is sufficient to press a sufficient amount of liquid into the pump and the Limiting the above-mentioned negative pressure can be achieved by the suction nozzle Absolute pressure drop below the vapor pressure of the liquid, which has the consequence that the Liquid evaporates and now steam, instead of the liquid, gets into the pump. As a result, the delivery rate to a fraction of the intended Flow rate drops. Furthermore, in this process - called cavitation - there is a excessive noise from condensation of the vapor bubbles is caused.
  • the liquid is tried, as already described above under its own sufficient hydrostatic pressure, e.g. B. from a storage container, to flow into the pump.
  • a minimum height of the liquid e.g. B. in said storage container
  • NPSH Net Positive Suction Head
  • the liquid cannot always be guaranteed, because this z. B. in one Dishwasher is not spatially possible and the structure of the dishwasher complicated and time-consuming or because an additional template is required Mass of liquid that is basically unused for the operation is undesirable.
  • the invention is therefore based on the object of a method for operating a To create a dishwasher of the type mentioned, in which energy and Water can be saved and there are no special inlet requirements for its use must be observed.
  • This object is achieved in that the cleaning liquid by means of of a pressurized, gaseous pumped medium.
  • the cleaning liquid is by means of a pressurized, gaseous medium conveyed at intervals. If the goods to be cleaned are acted on at intervals, everyone does so At the beginning of the application, an increase in pressure in the application cleaning liquid as well as at each end of the application a drop in the pressure in the application Cleaning fluid. In practice it has been shown that the alternating Rise and fall of the pressure of the cleaning liquid and the pressure caused alternating increases and decreases on the pollution the mechanical forces to be cleaned, a sufficient cleaning result with a shorter one compared to the prior art described above Duration of exposure is reached, which means the duration of the cleaning program is shortened.
  • the cleaning liquid is conveyed impulsively, with which the alternating rise and fall of the pressure of the cleaning liquid and the alternating rise and fall of the mechanical forces acting on the dirt on the goods to be cleaned very short period of time. in practice it has been shown that this Significant improvement in the cleaning result with a shorter duration of exposure of the items to be cleaned can be achieved.
  • Pulse duration becomes the cleaning effect of the pressurized goods applied cleaning fluid optimized.
  • the clocked pumping method is achieved by that the gaseous medium is pumped in one cycle, z. B. piston or diaphragm pump, etc. is promoted.
  • the gaseous delivery medium can also be clocked from a supply source Applying the cleaning liquid.
  • the cleaning liquid is by means of a Tactical plug process promoted, in which the cleaning liquid through the gaseous Pumped medium is pressurized, which alternates between two pressure levels is changed so that at a low pressure level at which a negative pressure prevails, sucked in and by applying the higher pressure level at which a Overpressure prevails, the cleaning liquid is conveyed in the desired direction of delivery becomes.
  • the cleaning fluid can still be low Inlet height can be sucked in in sufficient quantity.
  • the cleaning liquid is forced to be delivered through repression. Since the gaseous medium is also sucked in for compression must, with this measure, this already existing negative pressure also used to promote the cleaning liquid, especially for acceleration the flow of a new amount of cleaning fluid to be pumped.
  • the gaseous medium is expediently air, which is the most common Occurring gas is used to promote the cleaning liquid.
  • a partial program step "Drying" the gaseous medium into a treatment room the dishwasher passed, whereby the already existing gaseous medium - the air - when drying by blowing off the to be cleaned Well-preserved moisture, the drying result improves and the duration of the Sub-program step "drying" significantly shortened.
  • the cleaning liquid with that in the household dishwasher 25 water to be cleaned is not shown, that may be mixed with detergents or rinse aids and possibly also with worn ones Leftovers is dirty.
  • the household dishwasher 25 has a washing container 26 for placing and Rinsing of not shown goods to be cleaned, which by - in household dishwashers usually pivotable about a horizontal axis - not closer described door can be closed.
  • Dishwashing baskets are in the washing compartment 26 27, 28 arranged, in which the material to be cleaned, not shown, for. B. cutlery, plates, Cups, glasses, etc., which is classified with the cleaning liquid Spray devices, e.g. B. so-called spray arms 29, 30 according to the invention Procedure is applied.
  • the pump pot 9 or drain pan which collects from that arranged in crockery baskets, not shown, to be cleaned Cleaning fluid.
  • the cleaning liquid is cleaned by means of a pressurized gaseous medium, in the described embodiment of the invention Process promoted at intervals and impulsively.
  • the gaseous Pumped medium in the described embodiment is air.
