Abstract
The invention discloses a washing machine water level correction control method and a washing machine and belongs to the field of washing device control methods and washing devices. A problem of lack of accurate water level correction control method in the prior art is solved. The washing machine water level correction control method comprises steps of calculating a third value according to heating time of the washing machine, water temperature difference value before and after heating, and a water feeding amount, and determining whether to supply water according to a comparison result between the third value and a target value. The washing machine employs the above water level correction control method. Water level correction accuracy can be improved by the use of the control method; and the washing machine is more convenient and clothes washed by the washing machine are cleaner.
Description
Technical field
The present invention relates to water level of washing machine Corrective control method and the washing machine using the method.
Background technology
Washing machine is one of conventional household electrical appliance.Generally, laundry processes be all first place medicated clothing further according to
Family setting water level value or intelligent program calculates water level value to intake, but, because medicated clothing is immersed in water
In occupy the volume of part water and medicated clothing liquid level can be raised, the not equal factor of water absorption of different medicated clothing
Impact, leads to inflow to there is certain error.
Existing water level of washing machine Corrective control method is：Medicated clothing to be cleaned is put into after washing machine, selects manually
Select target water level；Automatically carry out weight perception, judge actual water level；Target setting water level and actual water level
Safety range；Calculate the error amount of target water level and actual water level；Whether error in judgement value is more than or equal to
If so, actual water level is set as target water level by safety range, if it is not, target water level is constant.This water level
Corrective control method is primarily present two defects：First, adopt the method relatively low to the accuracy of level correction,
There is no specifically accurate correction calculation method；2nd, in particular for some, there is the impeller laundry of heating function
For machine or roller washing machine, not only relatively low to the accuracy of level correction, and the water heating can be made more
Become the waste of the energy.
Content of the invention
It is an object of the invention to proposing a kind of higher water level of washing machine Corrective control of level correction accuracy
Method.
Another object of the present invention be propose a kind of using convenient washing machine.
For reaching this purpose, on the one hand, the present invention employs the following technical solutions：
A kind of water level of washing machine Corrective control method, by the water temperature difference before and after washing machine heat time heating time, heating
Value and water inlet value in any two worth go out the 3rd value, according to the 3rd value and desired value ratio
Result is judged whether to need moisturizing.
Further, the water temperature mathematic interpolation before and after being according to washing machine heat time heating time and heating when the 3rd value
During the actual water inlet value drawing, desired value is default water inlet value；Or
When the 3rd value is the washing machine that the water temperature difference intake value and heating according to reality before and after calculates
During actual heat time heating time, desired value is to be calculated with the water temperature difference before and after heating according to default water inlet value
Washing machine theory heat time heating time；Or
When the 3rd value is before the heating being calculated actual heat time heating time according to default water inlet value and washing machine
During rear theoretical water temperature approach, desired value is by detecting the actual water temperature difference before and after the heating obtaining；Or
