Description
Technical field
The present invention relates to washing machine control technology field, particularly relate to a kind of washing machine water bit correction control method and system.
Background technology
Washing machine user manually select after water level, if the water level that the water table ratio actual loading of current manual selection needs is much lower, can cause clothing serious wear in washing process, and even motor rotation blockage, causes damage to clothing or washing machine; If the water level that the water table ratio actual loading of current manual selection needs is high a lot, can cause the waste of the resources such as in washing process water power, the prolongation of wash time and cleaning than undesirable.
In prior art, conventionally control water level with level sensor.Level sensor is just equivalent to pressure switch, when setting after what a force value, produces hydraulic pressure after water filling, reaches just energising automatically after force value, has reached the effect of switch.Washing machine water bit switch is divided into two kinds of electronic type (adjustable resistor type) and switching regulators, and to be all the air pressure that produces while rising by water level be delivered to sensor by pipeline resistance is changed or internal switch connects to make computer to produce action for they.Level sensor easily damages, and fault occurs after damage, can to produce that inaccurate, the long water filling of water filling is not turned round, do not dry after drained water etc.
Therefore,, for above-mentioned technical problem, be necessary to provide a kind of washing machine water bit correction control method and system to overcome above-mentioned defect.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of washing machine water bit correction control method and system of automatic adjustment water level.
