Abstract
The present invention discloses a kind of method to the uneven perception of washing tube undergarment, by using DC brushless motor, because being proportional relationship between the operation torque and electric current of the motor, you can carry out uneven perception with the feedback by motor current value；So as to real-time control can be realized to imbalance perception, uneven perception will not be just carried out when washing machine has occurred and that high vibration or displacement；And perceived effect is more accurate.
Description
Technical field
The present invention relates to the clothing imbalance cognitive method of washing machine field, especially a kind of washing machine.
Background technology
In current washing machine, especially in dehydration arrangement balancing to clothing in washing tube have it is very high will
Ask, if because laundry load is collected at a certain region in washing tube, when washing tube is rotated due to internal load distribution not
Very big centrifugal force will be produced so as to produce vibration even to shift.
The clothing imbalance perception algorithm of prior art is as follows：
Many washing machines are to perceive the vibration that laundry machine dehydration is by the vibration of original paper in level sensor, and can not
Weight according to clothing distinguishes different vibratory outputs.This kind of cognitive method is very inaccurate, and control postpones, and washing machine is in dehydration
It is susceptible to movement.
The technical problem point：
The control is usually present delay, only when washing machine has occurred and that high vibration, can just perceive the vibration；
How much the control can't distinguish laundry amounts, it may occur that the perception of mistake.If laundry amounts are larger, its vibratory output
Relatively small amount clothing can become big, but sensor may occur open circuit because larger vibration is mistakenly considered uneven.
In a word, the control is inaccurate, it is impossible to meet customer to laundry low noise, the requirement of high security.
Therefore, it is necessary to a kind of new technical scheme is solving the above problems.
The content of the invention
The purpose of the present invention is directed to the deficiency of prior art presence, there is provided one kind being capable of real-time perception washing tube Ei clothings
Unbalanced method.
To achieve the above object, the present invention can be adopted the following technical scheme that：
A kind of method to the uneven perception of washing tube undergarment,
The motor for driving washing tube is DC brushless motor, sets some range of motor speeds, and correspondence each motor turn
Fast scope pre-sets corresponding Table values；
Table values are a determinating reference values, if perception value is more than a reference value of this setting, washing machine will not enter
Row dehydration；
The Q shaft current values of motor are detected in time period in each range of motor speeds in real time, and is converted into imbalance
Value Iq_Value；
Unbalanced value Iq_Value is the Q shaft current values required for actual motor；
Load is more uneven, and the electric current of actual motor is bigger, i.e. Iq_Value values are bigger；
Whether uneven judge clothing by contrasting Iq_value and Table values；If Iq_value is more than Table values,
Then think that the clothing in washing tube is uneven.
Compared with background technology, the characteristic that the DC brushless motor for using has is：Because of the operation torque and electricity of the motor
It is proportional relationship between stream, if clothing is uneven during dehydration, reaches the rotating speed (RPM) of setting, then needs torque higher,
Corresponding current of electric can be bigger, and uneven perception is carried out by the feedback of motor current value；The imbalance is perceived can be with
Real-time control is realized, uneven perception will not be just carried out when washing machine has occurred and that high vibration or displacement.And；Contrast is existing
Some control algolithms are more accurate, and uneven perceived effect is more preferable
The present invention can additionally provide a kind of method to the dehydration of washing tube undergarment, adopt the following technical scheme that：
Comprise the following steps：
(1) motor for, driving washing tube is DC brushless motor；Some range of motor speeds, and corresponding each electricity are set
The machine range of speeds pre-sets corresponding Table values；
(2), residual water carries out draining in washing tube；
(3), spun laundry amount is perceived；
(4) the Q shaft current values of motor, are detected in the time period in each range of motor speeds, and is converted into imbalance
Value Iq_Value；Unbalanced value Iq_Value is the Q shaft current values required for actual motor；
(5) whether, to judge clothing by contrasting Iq_value and Table values uneven；If Iq_value exceedes
Table values, then it is assumed that the clothing in washing tube is uneven, now carries out clothing leveling；
(6), continue to be dehydrated.
The above-mentioned method to the uneven perception of washing tube undergarment is equally added in the method for the dehydration, in dehydration
In can in real time the imbalance perceive.
Specific embodiment
With reference to specific embodiment, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention, after the present invention has been read, those skilled in the art are to various equivalences of the invention
The modification of form falls within the application appended claims limited range.
Embodiment one, is the method for the uneven perception of washing tube undergarment, specially：
The motor for driving washing tube is DC brushless motor, sets some range of motor speeds, as shown in table 1.Wherein control
Correspondence sign when system interval is for the different bucket ranges of speeds.
| Control interval | MS1 | MS2 | RS1 | RS2 | RS3 | RS4 | RS5 |
| Bucket rotating speed | 40~89 | 90~115 | 130~150 | 151~170 | 171~190 | 191~230 | 231~270 |
Table 1
Also, correspond to each range of motor speeds and pre-set corresponding Table values；Here it is possible to further is right
Table values are refined, and e.g., correspond to each range of motor speeds, and account for nominal load according further still to the load of washing tube undergarment
The scope of ratio is further divided into some corresponding new Table values.Table values are a determinating reference values, if perception value
More than a reference value that this sets, washing machine will not be dehydrated.As shown in table 2.
Table 2
The Q shaft current values of motor are detected in time period in each range of motor speeds in real time, and is converted into imbalance
Value Iq_Value；That is unbalanced value Iq_Value is the Q shaft current values required for actual motor.
Whether uneven judge clothing by contrasting Iq_value and Table values；If Iq_value is more than Table values,
Then think that the clothing in washing tube is uneven.
