Definitions

  • the invention relates to a method for switching a Liquid distribution device of a dishwasher and a dishwasher with a reversible Liquid distribution means.
  • the sensor signal is a Control device supplied, in turn, the speed of a Circulating pump as a function of the sensor signal sets.
  • the dishwasher of DE 100 42 781 A1 comprises a upper and a lower spray arm, as well as a Liquid distribution device in the form of a Reversible multi-position valve, depending on the position of the valve the upper, the lower or both Spray arms are treated with cleaning liquid.
  • the Valves are assigned to light barriers, which are the position of a Capture spherical valve body within the valve.
  • the photoelectric sensors can be used to detect the Turbidity of the liquid can be used. It will proposed, the turbidity signal of the photocell to evaluate used cleaning fluid against exchange fresh.
  • the liquid distribution device at least three switch positions on, in Dependence of the detected state of soiling Cleaning liquid to be approached selectively. Leave it the cleaning efficiency increase even further, if for example, by the admission of both baskets in the dishwasher on the admission of only lower crockery basket is switched to strong there To clean soiled dishes particularly intensively.
  • a change of the Pollution state of the cleaning liquid above the specified range can be determined by changing the switching state of the liquid distribution device at Continuation of the cleaning cycle, for example, all Dish baskets are treated with cleaning liquid. As a result, items to be washed in previously treated dish rack further cleaned.
  • the switch position changes when a given upper Limit is exceeded.
  • Particularly advantageous is here by switching from an admission of the upper and converted lower basket or upper crockery basket to an admission of only the lower dish rack after the limit is exceeded. This will avoided that heavily contaminated cleaning fluid on the items to be washed in the upper dish rack and there to a Reverse pollution leads.
  • This is especially optimal Switching in the current program section tuned to a initially taking place, exclusive cleaning of the / upper crockery basket / baskets of which / on the cleaning Both / all baskets was switched. At a such process ensures that the items to be washed in or already sufficiently selected in the upper dish racks Program section was cleaned.
  • the total purge duration can be shortened if at Exceeding the limit or gradient, for example all crockery baskets are supplied with cleaning liquid Be as separate, to the admission of the upper Crockery basket subsequent rinsing time for only the lower crockery basket is necessary. The cleaning of the The items to be washed in the upper and lower rack then take place due to the high contamination of the dishes in the upper Dish rack at the same time.
  • the temporal gradient of the contamination state monitors and causes a changeover if this over a certain value. This can prematurely be found that strong in one of the baskets contaminated items to be stored.
  • Switching the liquid distribution device next to the other crockery basket of the relevant crockery basket continues treated with cleaning liquid.
  • a switchable Liquid distribution device with several Switch positions provided by changing the Switch position the distribution of cleaning fluid in the Change dishwasher interior.
  • a sensor detected the soiling state of the cleaning liquid, for example, by measuring the turbidity of the cleaning fluid and / or their conductivity.
  • a control device receives the signals from the sensor and evaluates them out.
  • the switchable liquid distribution device of the Controlled control device to switch by the to change the instantaneous distribution of the cleaning fluid.
  • the cleaning efficiency becomes by monitoring the state of contamination of the Cleaning fluid and depending on it by optimization the cleaning liquid distribution increased.
  • Fig. 1 shows a schematic representation of the liquid circuit at a dishwasher.
  • a dishwasher 1 of the dishwasher are an upper spray arm 2 and a lower spray arm 3 for acting in crockery 4 stored dishes arranged with liquid.
  • the of the Low spray 2, 3 sprayed liquid is at the bottom of the Spülraums 1 collected in the dishwasher sump 5.
  • the Trapped fluid is fed via one inlet Recirculating pump 6 sucked in and through a connecting line. 7 a switching valve 8 is supplied.
  • am Changeover valve 8 two photocells 12 arranged, which also serve as turbidity sensors and the clouding of the Detect flushing fluid through entrained impurities.
  • the control unit 15 controls the speed of the Pump, so that the switching valve 8 by timing the speed switched between the individual positions becomes.
  • a user of the dishwasher over a control panel 16 select program options so that they are included the control by the control unit 15 as a modification of Standard program run.
  • the turbidity of the liquid can be to optimize the cleaning result. So can at a Cleaning by the application of liquid Crockery baskets 4 from top to bottom a re-pollution of the items to be washed in the upper dish rack to be reduced. Furthermore, depending on the turbidity, the duration, the Spray arm 2, 3 with cleaning fluid or rinse aid is changed depending on the turbidity.
  • the user can For example, the degree of pollution by means of a Program selector switch in the display of the dishwasher adjust the monitoring by the at the selected option customized program is optimized.
  • the gradient G1 can also be used for differential estimation of achievement of a Pollution degree are used. For example, if already the fresh liquid due to the used Detergent has a basic value of turbidity.
  • this monitoring may be additional used to determine the duration of a program section to adapt according to the needs.
  • this monitoring may also be described by the cleaning intensity Increasing or decreasing the speed of the pump 6 adjusted become.
  • program selection by the user There is the possibility to choose an intensive program to heavily soiled dishes in the lower basket especially intensive to clean.
