Description
Technical field
The present invention relates to a kind of for the method for washing machine of the operation with pressure sensor and suitable for the method
Washing machine.The invention particularly relates to a kind of washing machine, the washing machine have alkali liquor container, the cylinder for receiving washings,
For the drive motor of cylinder, the hydrostatic pressure measured of liquid, aqueous height for being determined as in alkali liquor container
The position state of the pressure sensor, control device and the vibrational system for being used to determine washing machine in washing machine run duration of p
With at least one state sensor of behavior, the vibrational system includes alkali liquor container, cylinder and drive motor, and is related to one
Plant and be applied to the washing machine for carrying out the method.
The content of the invention
It is important that alap water requirement for washing machine operation.Additionally, in the case of using less water, disappearing
The less electric energy of consumption is used for the required water for washing process of heating.On the other hand, the water yield for being used must be enough
Many, 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
What water requirement for a collection of clothing to be washed and also providing was sufficiently used for washing free bleachinges and dyeing liquid measure.
When in program control washing machine by for the species sum of the water yield needed for washing 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
In other words the water yield in cylinder (hereinafter also referred to as " laundry drum ") before actual washing process with the time as short as possible
Completely and homogeneously soak.Additionally, the water yield used for wetting should be reproducible, thus especially also ensure heat energy
It is brought into renewablely in water.
Thus, the purpose for soaking the stage (also referred to as " wetting phase ") is to provide the optimal water yield for washing process
And with regard to the information of useful load.Therefore, the wetting stage is very important for each washing procedure.In order to carry
For the optimal water yield, during cylinder is reversed and/or in inactive state, generally consider pressure value come for being analyzed place
Reason.
For example it is known that in the following way realize wetting, it is determined that the water yield be flowed into comprising clothing cylinder neutralization
The cylinder that rotation is made after the drenched stage stops.Water then drains off from washings, until it reaches almost stable state, described
State can according to hydrostatic pressure nearly constant for water or only the slight pressure value for changing proving.Then according to
The degree that pressure when cylinder remains static increases determines whether saturation is with water for washings.
In order to adjust during wetting stage and washing stage used in washing machine liquid, aqueous (generally comprises clean
Water or washing alkali liquid, the washing alkali liquid be used for clean surfactant to be used) packed height, electromagnetism is usually used

Afterwards, according to the current latched position of commonly used friction shock absorber changing the position of vibrational system, the friction damping
Device changes during washing process generally according to loading, the water yield, rotation direction etc..
These factors affect the position state of vibrational system, so as in the analyzing and processing of the pressure value by measured by pressure sensor
In be likely to occur error or inaccuracy.When water level is measured, the influence factor mentioned before is not considered so far.In order to obtain by
Hydrostatic pressure measured by pressure sensor as far as possible accurately and therewith in view of the convictive value of water level, probable value
Obtain it is desirable that, not only sensing qualitatively but also quantitatively the effect of these influence factors and correspondingly to by pressure sensor institute
