Specific embodiment
To keep the technical problems solved, the adopted technical scheme and the technical effect achieved by the invention clearer, below
In conjunction with attached drawing and pass through specific embodiment to further illustrate the technical scheme of the present invention.
As shown in Figure 1, present embodiments providing a kind of judgment method of washing machine bias, which claimed in clothing
Judged on the basis of weight, and is judged before dehydration procedure starts.Specifically, clothing is put into washing tub in user
After object, before washing procedure starts, the weight of dry clothing in washing tub is measured.According to the weight for the drying clothing that measurement obtains
Amount obtains the critical weight of its corresponding wet wash, the maximum eccentricity amount institute that critical weight allows when working normally for washing machine
The weight of corresponding wet wash, the critical weight can be program preset weight value.After drainage procedure, dehydration procedure opens
Before beginning, the weight of wet wash in washing tub is measured, by comparing the weight and critical weight of wet wash, if the weight of wet wash
Greater than critical weight, then judge that washing machine is in load eccentric state.
In the present embodiment, the weight of dry clothing and the weight of wet wash can be measured by the method for fuzzy weighing
's.Fuzzy weighing method is the common weighing method of one kind of existing rotary drum washing machine, and fuzzy weighing is to make motor according to one
Fixed one kind for turning to stop to obtain the weight of clothing according to the situation of change that driving plate is supplied to the current value of motor than positive and negative rotation
Method does not limit the specific method of fuzzy weighing in the present embodiment, as long as fuzzy weighing method in the prior art is equal
It is applicable in the judgment method of washing machine bias in this present embodiment.When being put into dry clothing, can be obtained by fuzzy weighing
The weight of dry clothing.After draining, before dehydration procedure starts, if washing tub, there is no load eccentricity issues, motor turns
Dynamic driving impeller rotation, clothing at this time is only under gravity with impeller friction, therefore driving plate is supplied to the electricity of motor
Flow valuve is smaller, and fuzzy obtained numerical value of weighing is lower.When there are load eccentricity issues in washing tub, the inner wall of clothing and washing tub
Contact more, clothing can generate friction with the inner wall of washing tub, and inner wall there are certain resistance, therefore drives the clothing in rotation
The current value that movable plate is supplied to motor is larger, and fuzzy obtained numerical value of weighing is higher.It is wet when being obtained by fuzzy weighing measurement
When the weight of clothing is greater than the critical weight of program setting, illustrate that the friction valve of clothing and washing tub inner wall is larger, then judgement is washed
Clothing machine is in load eccentric state, needs to be balanced adjustment to the clothing in washing tub, to avoid during the dehydration process, does washing
There is the phenomenon that significantly waving because eccentric excessive in bucket, avoids washing tub and cabinet from colliding, reduces noise, improves making for user
With experience.
Eccentric judgement is carried out when the judgment method of washing machine bias in the present embodiment is preferably smaller to the load of washing machine.
When washing machine load it is smaller and be not present eccentricity issues when, clothing is stacked on impeller substantially, not with the contact of washing tub inner wall,
When occurring eccentric, clothing is contacted with washing tub inner wall, and wall friction increases the resistance in rotary course in clothing and washing machine, from
And washing machine can be judged with the presence or absence of bias according to the weight of the wet wash of measurement.When washing machine load is larger, clothing heap
It is folded inevitably to be contacted with the inner wall of washing tub, it is deposited between clothing and washing tub inner wall in eccentric and uninfluenced situation
In frictional force, washing machine is unable to judge accurately with the presence or absence of bias by comparison critical weight and the weight for measuring wet wash.
Certainly, in other embodiments, the weight of dry clothing and wet wash can also be measured by other means.
When obtaining the critical weight of the corresponding wet wash of dry clothing, the weight of dry clothing can be divided into multiple
Weight section, each corresponding critical weight for being preset with a wet wash in the weight section, facilitates acquisition critical weight.To make
The available corresponding critical weight of weight value of dry clothing, multiple weight sections can be continuously arranged.Specifically, adjacent
Two weight sections in, the minimum value in a weight section is equal with the maximum value in another weight section, guarantees dry clothing
Any weight value of object can be corresponding with a critical value.
To improve the accuracy that critical weight is chosen, the interval between the maximum value and minimum value in each weight section is unsuitable
It is excessive.The distribution of weight section is more intensive, and the critical weight value of acquisition is more accurate, and finally obtained bias judging result also can be more quasi-
Really.Specifically, the interval between the maximum value and minimum value in weight section can be 0.5kg~1.0kg, such as can be
0.5kg, 0.6kg, 0.7kg, 0.8kg, 0.9kg, 1.0kg etc., specific numerical value can determines according to actual conditions, or according to
Family needs to choose.
For the accuracy for improving the judgement of washing machine bias, can be realized by improving the accuracy that critical weight is chosen.
In terms of improving the accuracy that critical weight is chosen, it can not only be realized by dividing more weight section, also
Critical weight appropriate can be chosen according to the type of clothing material.Due to the water imbibition and difference of hardness of the clothing of unlike material
It is not larger, for the accuracy for improving the judgement of washing machine bias, the drying of unlike material can be established according to the unlike material of clothing
The database of the critical weight of the corresponding wet wash of the weight of clothing.User selects corresponding kinds of laundry before washing starts,
According to the type for the weight and clothing material for measuring obtained drying clothing, corresponding wet clothing is obtained in corresponding database
The critical weight of object, so as to improve critical weight and wet wash weight comparing result accuracy.Specifically, snow can be created
The corresponding database of the materials such as spinning, natural feather, cowboy and cotton prestores the dry weight institute of respective material in each database
The critical weight of corresponding wet wash, to further increase the accuracy of eccentric judgement.
