Definitions
- the invention relates to a method for operating a dishwasher.
- FR-PS 24 17 967 describes a method for operating a dishwasher a wash program that can be selected from seven sub-program steps with the use of rinsing liquid known, in which the degree of contamination of the washing liquid in the sub-program steps is determined and according to the degree of contamination sub-program steps are inserted or skipped and each sub-program step with a rinsing liquid change ends.
- the degree of contamination of the rinsing liquid determined from the spray pressure generated by the circulating pump.
- each of the methods for operating a dishwasher of the aforementioned type only a certain type of pollution of the stored, dishes to be cleaned are determined and with only one-sided measures, namely inserting or hiding partial program steps and / or leaving or Change the washing liquid, tried the washing program to keep the dishes dirty to adapt and thereby save energy and water.
- the invention is therefore based on the object of a completely automatic method for Operate a dishwasher to create, in which an incorrect operation by the User is completely excluded, reducing energy and water consumption Dishwasher is limited to the minimum possible.
- This object is achieved in that the dishwasher at the beginning of the program is only started and that for the progress of the rinsing process parameters to be set depend on at least one for the progress of the Winding parameters necessary and influenced by him, set parameters will.
- the user provides So not a program consisting of selectable program steps, but he only starts the dishwasher and based on the determined parameter values the following parameter values are set, whereby a completely self-controlled Method for operating a dishwasher is created, in which a Incorrect operation by the user is completely ruled out and thus the energy and Water consumption of the dishwasher is limited to the lowest possible level becomes.
- the degree of contamination of the rinsing liquid is determined and is based on the determined degree of contamination of the rinsing liquid over the duration of the corresponding Sub-program step and / or the continuation or termination of the corresponding Sub-program step and / or a complete or partial rinsing liquid change and / or via the temperature of the rinsing liquid to be set and / or via a further determination of the degree of contamination of the washing liquid and / or via a Add addition agents and / or the amount of addition agent to be added and / or decide on the time of adding the addition means.
- the method according to the invention is based on a further preferred feature of the invention further improved in that the increase in at least one partial program step the degree of contamination of the winding liquid is determined and based on a comparison with a further determined value for the degree of contamination of the rinsing liquid the duration of the corresponding sub-program step and / or via the continuation or Completion of the corresponding sub-program step and / or via a complete one or partial rinsing liquid change and / or the temperature to be set Flushing liquid and / or via a further determination of the degree of contamination of the Rinsing liquid and / or by adding additives and / or by adding Amount of additive and / or the time of adding the additive is decided.
- the increase in the degree of contamination of the rinsing liquid provides information about other types of contamination and degrees of contamination of the stored, to be cleaned Dishes as being statically determined at a predetermined program time Degree of contamination of the rinsing liquid, so that taking into account the increase in Degree of pollution and its comparison with a statically measured degree of pollution a more targeted selection of the actions to be used on the stored dishes to be cleaned.
- the degree of contamination of the rinsing liquid from the turbidity of the rinsing liquid and / or from that generated by the circulating pump Spray pressure determined. Also the selection of the correct method for determining the degree of pollution the rinsing liquid enables a more precise and targeted determination the type of soiling and the degree of soiling of the stored, to be cleaned Dishes.
- pre-rinse which is known to use fresh water without the addition of detergent takes place, mainly easily removable dirt particles removed from the dishes
- a sub-program step "first pre-rinse” after the filling of rinsing liquid has ended the increase in the degree of contamination of the rinsing liquid over a predetermined duration is determined and on the basis of the determined value for the degree of contamination the duration of the sub-program step "first pre-rinse" is determined for the rinsing liquid.
- the increase in pollution is an essential more precise determination method than a static determination of the degree of pollution, since with a static determination only an instantaneous condition of the rinsing liquid is recorded, but none over the course of the entire sub-program step Makes statement possible.
- the determination of the increase in the degree of pollution of the Rinsing liquid is a targeted selection of the only ones in the sub-program step "first pre-rinse” possible influence - the duration of the sub-program step "first Pre-rinse "- enables.
- a rinsing liquid change is provided at the end of the sub-program step "first pre-rinsing" and after the duration of the sub-program step "first pre-rinsing" determined from the first determination of the degree of contamination of the rinsing liquid, the degree of contamination of the rinsing liquid is determined again and is based on the comparison of the both determined values for the degree of contamination by continuing or ending the sub-program step first pre-rinse or the entire sub-program step "pre-rinse” and / or via a complete or partial change of rinsing liquid between the sub-program step "first pre-rinse” and the sub-program step "second pre-rinse” and / or between the sub-program step "pre-rinse” and the subsequent sub-program step “cleaning" and / or via decided the addition of an addition.
- a rinsing liquid change is provided, there are further possibilities for influencing the dishes, namely the use of new rinsing liquid, the use of addition agents and the duration of the sub-program steps, over their duration Decision is made using a specially selected investigation method and decision method.
