Description
Technical field
The present invention relates to washing machine field, the specifically control method of washing machine, especially a kind of automatically cleaning washing machine row
Dehydration controlling method.
Background technique
Existing washing machine is by the impeller of motor driven bottom of the barrel to be alternately rotated realization drive clothing along counterclockwise
Rolling, rotation, make phase mutual friction between clothing and clothing, clothing and impeller, clothing and bucket and achieve the purpose that clean clothing.
When laundry, various solia particles are contained in water, such as: scale that calcium ion and calcium carbonate in water are formed, laundry detergents
Educt in soap lye is washed clothes fiber bits, the human body fallen and rubs the grease stain protein stayed on washing clothes and various organic
Residue, the bacterium brought by washing clothes and other substances, form suspension.Due to diffusion be it is unconditional absolutely,
Particle is smaller, spreads more serious.For being less than several microns of particle, such as virus or protein, it is easy to diffuse to washing machine
In the interlayer of bucket, accumulates over a long period and be attached on washing machine inner tub outer wall and outer barrel inner wall, form usually said dirt.These are dirty
Dirt can cause secondary pollution to clothing, threaten the health of user.
Based on the above situation, the program that many automatic washing machines are all equipped with dedicated for nightstool, i.e. bucket cleaning procedure.
Two kinds of drum cleaning program control method for full automatic washing machine are disclosed application No. is the Chinese patent of CN200810061541.X, two
The nightstool principle of kind method is all to rinse dirt using centrifugal force.Method one: after the completion of last time rinses, drain valve is opened
It opens, draining starts, until the water level in the water level controller monitoring outer barrel of signal deteching circuit reaches the first water level；It is computer program controlled
Device controls drain valve and closes, and draining stops；Computer programmed controller controls motor is powered, interior bucket rotation, to the time of computer program controller
Controller detects the first setting time；The power-off of computer programmed controller controls motor, interior bucket rotates freely, to computer program controller when
Between controller detection reach the second setting time；Computer programmed controller controls drain valve is opened, and draining starts, until signal detection electricity
Water level in the water level controller monitoring outer barrel on road reaches the second setting water level；Into normal dehydration procedure.Method two: last
After the completion of primary rinsing, drain valve is opened, and draining starts, the water in the water level controller monitoring outer barrel of signal deteching circuit

Specific embodiment
A specific embodiment of the invention is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, automatically cleaning washing machine of the present invention includes outer barrel 1 and interior bucket 2, between 2 outer wall of 1 inner wall of outer barrel and interior bucket
Space 3 in be equipped with clean bucket wall cleaning particle 4,1 bottom of outer barrel installation one can collect cleaning particle drain valve 5, row
When water, cleaning particle is finally discharged into drain valve 5 and is collected with water level decreasing, after water inlet next time, then increases with water level and enters sky
Between in 3.
Water level phase change relationship corresponding with interior bucket revolving speed is equipped in washing machine of the present invention, washing machine receives draining and refers to
It enables, opens drain valve；Judge water level of washing machine；Washing machine is right according to the setting water level stage where the height of water level of the detection
The revolving speed of interior bucket should be controlled, the frequency of cleaning particle and inner and outer barrel wall friction, collision is adjusted.
Specifically, row's dehydration was divided at least two control stages according to water level height by washing machine, each stage is set
There is different interior bucket rotating manners, in the water level lower stage, interior bucket revolving speed is bigger.During getting rid of water, washing machine is according to inspection
The water level of survey selects the corresponding control stage, with the stage preset interior bucket rotating manner control interior bucket rotation.
Washing machine capacity is smaller, and when draining, the variation range of water level is smaller in space, and washing machine is in row's dehydration setting
The control stage it is also fewer.According to the capacity of existing washing machine, the stage that controls is 2-5, this is because capacity is smaller, it is maximum
The water of water level is fewer, and drainage speed quickly, if drainage procedure frequently changes interior bucket revolving speed in the short time, reduces motor and uses the longevity
Life, secondly, the washing machine that capacity is smaller, the possibility that bucket wall forms dirt is also fewer, and in washing process, cleaning particle substantially can
