Summary of the invention
It is important that alap water requirement for washing machine operation.In addition, disappearing using less water
Less electric energy is consumed for the water needed for heating for washing process.On the other hand, used water must be enough
More, it is possible thereby to be sufficiently used for soaking and washing washings to be washed.It is important, therefore, that understanding as precisely as possible
For a collection of clothing to be washed water requirement and also provide and be sufficiently used for the free of washing and bleaching and dyeing liquid measure.
When in program control washing machine by the type sum number in order to wash required water and washings to be washed
Amount preferably should so optimize the wetting stage when being matched so that every batch of clothing with it is mutually coordinating herein, in alkali liquor container
The water in roller (hereinafter also referred to as " laundry drum ") is before actual washing process with the time as short as possible in other words
Completely and homogeneously soak.In addition, for soak and the water that uses should be it is reproducible, thus especially also guarantee thermal energy
It is brought into water renewablely.
The purpose for soaking stage (also referred to as " wetting phase ") as a result, is to provide the optimal water for washing process
And the information about useful load.Therefore, the wetting stage is very important for each washing procedure.In order to mention
For optimal water, during roller reverses and/or in stationary state, usually consider pressure value come for carrying out at analysis
Reason.
Such as it is known that in the following way realize wetting, in the roller that determining water is flowed into comprising clothing and
Stop the roller of rotation after the drenched stage.Water then drains off from washings, until reach almost stable state, it is described
State can be proved according to the pressure value that is nearly constant or only slightly changing of the hydrostatic pressure for water.Then according to
The degree of pressure increase when roller remains static determines whether washings is saturated with water.
In order to adjust liquid, aqueous used in the washing machine (generally comprise clean during wetting stage and washing stage
