Step 160, judges that whether the mean power, more than reference power, is then to perform step 170, otherwise performs step
180。
Specifically, the reference power is used to be contrasted with mean power.It is noted that washing machine is being mounted with interior bucket
When, the power of motor work is smaller, and washing machine is not when installing interior bucket, and the power of motor work is larger.Specifically, each embodiment
In, motor is direct current generator, and from the characteristic of direct current generator, the load of same weight is got over and concentrates on bearing, that is, load
The drive shaft of motor is more concentrated on, then the torsional forces of motor is smaller, and the operating current of motor and operating power are in torsional forces
Direct ratio, therefore, the power of motor is also just smaller, after being mounted with interior bucket, because the diameter of interior bucket is smaller, and interior bucket and interior
The load of the clothing in bucket is concentrated on around bearing, therefore, the torsional forces of motor is smaller.And interior bucket is not installed in working as washing machine
When, then being relatively large in diameter due to outer barrel, the torsional forces of motor is larger, therefore, the power of motor is also bigger.
When mean power is more than reference power, then show in rotating several times, the operating power of motor is larger, can sentence
It is disconnected to draw, interior bucket is not installed in washing machine, therefore, perform step 170；When the operating power of motor is less than reference power, then table
The operating power of bright motor is smaller, therefore, can determine whether to draw, interior bucket is mounted with washing machine, perform step 180.
Step 170, obtains the first program for washing.
For example, first program for washing is outer barrel program for washing, for example, first program for washing is suitable for outer barrel washing
Program for washing, for example, first program for washing for interior bucket is not installed when, control washing machine work program for washing.Due to sentencing
Disconnected result is not install interior bucket, therefore, obtain the first program for washing.First program for washing of the acquisition is used to control washing machine root
The program done washing according to outer barrel is operated.It is noted that in this step, the first program for washing of acquisition can export for
Family selects, it is also possible to directly perform.
Step 180, obtains the second program for washing.
For example, second program for washing is interior bucket program for washing, for example, second program for washing is suitable for the washing of interior bucket
Program for washing, for example, second program for washing for be mounted with interior bucket when, control washing machine work program for washing.Due to sentencing
Disconnected result is to be mounted with interior bucket in washing machine, therefore, the second program for washing is obtained, the second program for washing of the acquisition is used to control
Washing machine is operated according to the program that interior bucket is done washing.It is noted that in this step, the second program for washing of acquisition can be with
Output is for user's selection, it is also possible to directly perform.
For example, first program for washing includes some laundry subprograms, and for example, institute respectively with second program for washing
The combination that the first program for washing is respectively the laundry subprogram of some settings with second program for washing is stated, so, can be right
Different laundry items flexibly realizes various targetedly laundry effects.Specific laundry subprogram and combinations thereof, including hold
Capable sequencing etc., can be set according to the program for washing of existing outer barrel or interior bucket.
In above-described embodiment, by detecting mean power of the motor in rotating several times, detect motor at this several times
Whether whether the mean power in rotation is more than reference power, and then judges be mounted with interior bucket in washing machine, according to judged result
Different program for washing are obtained, and then enables that the state that program for washing interior bucket current with washing machine is installed more is matched, it is real
Show the automatic acquisition of the program for washing of washing machine, without artificial operation, effectively prevent the generation of security incident.
For example, the first program for washing and the different setting of the second program for washing.The laundry journey of the program for washing of outer barrel and interior bucket
Sequence is different, is conducive to the reasonable control of the work to the different parts of washing machine so that each component working is more reasonable, more pacifies
Entirely, it is to avoid security incident occurs.
In order to improve control efficiency, output the first laundry journey is also included in one embodiment, after step 170
Sequence, for example, also including output second program for washing after step 180.
For example, obtaining first program for washing, first program for washing is exported；For example, obtaining second laundry
Program, exports second program for washing.
For example, power contrast's step：Whether the mean power is judged more than reference power, is then to obtain the first laundry journey
Sequence simultaneously performs the first program for washing, otherwise obtains the second program for washing and performs the second program for washing.
In the present embodiment, output program for washing is selected for user, and the program for washing is operated to automatically generate without user,
Therefore, after output, user only needs to determine, reduces user's operation, and be prevented effectively from program exception caused by maloperation, it is to avoid
Washing machine abnormal work and the security incident that causes.For example, after the determine instruction for receiving user, then washing according to the determination
Clothing programme-control washing machine works.For example, after the first program for washing of output, determine instruction is received, according to the first program for washing control
Washing machine work processed, for example, after the second program for washing of output, receiving determine instruction, washing machine is controlled according to the second program for washing
Work.In the present embodiment, user only needs to click on and determines to can perform program for washing so that the operation of user is more convenient, improves
Control efficiency, and it is prevented effectively from security incident.
In order to further improve the control efficiency to washing machine, in one embodiment, basis is also included after step 170
The first program for washing control washing machine work, for example, also including being controlled according to second program for washing after step 180
Washing machine works.
For example, obtaining first program for washing, washing machine work is controlled according to first program for washing；For example, obtaining
Second program for washing is taken, washing machine work is controlled according to second program for washing.
In the present embodiment, in the mean power of detection motor, after getting program for washing according to judged result, then basis is obtained
The program for washing control washing machine work got, and without manually operating, you can automatically controlling for washing machine is realized, is effectively improved
To the control efficiency of washing machine, the current state of washing machine is more adapted to due to the result for judging to obtain, therefore, it is possible to effective
The security incident for avoiding washing procedure of washing machine abnormal and causing.
In order to accurately obtain the mean power of washing machine, and then accurately judge whether washing machine is mounted with interior bucket, at one
In embodiment, step 120 includes：The motor is controlled along clockwise direction and to rotate in an anti-clockwise direction several times respectively.
In the present embodiment, washing machine startup after, before being washed, controlled motor respectively along clockwise direction with it is inverse
Clockwise is rotated several times, for example, rotate clockwise and rotate counterclockwise intersection carry out, for example, controlled motor is along clockwise
After rotating several times, controlled motor is rotated counterclockwise several times.It is noted that before being washed, washing machine has
It is likely to be at fully loaded, it is also possible in zero load, it is also possible in part load condition, therefore, the weight in washing machine may divide
Cloth is uneven, therefore, only from unidirectional rotation, or power is obtained from single revolution, it is possible to there is larger error,
Therefore, in the present embodiment, by repeatedly rotation, on the one hand, so that the Load Balanced distribution in washing machine, on the other hand, repeatedly
Average to reduce error, so that the mean power for obtaining is more accurate, really obtain the mean power of washing machine, and then
Accurately judge whether washing machine is mounted with interior bucket, so as to obtain program for washing according to accurate judged result, control washing machine work
Make so that clean result is more preferably.
In order that judged result that internally whether bucket is installed is more accurate, in one embodiment, the reference power
The power of motor during not place interior bucket and zero load in outer barrel, the power is referred to herein as the first power, i.e. described
Reference power is the first power of motor when interior bucket and zero load are not placed in outer barrel；Also can be regarded as not placing interior in outer barrel
The power of the motor is the first power when bucket and zero load.
In the present embodiment, when washing machine does not install interior bucket, outer barrel no-load running, the corresponding power of motor is the first work(
Rate, using first power as reference power.
Specifically, the characteristic of direct current generator understands that the load of same weight is got over and concentrates on bearing, that is, load gets over concentration
In the drive shaft of motor, then the torsional forces of motor is smaller, and the power of motor is also just smaller, and load gets over dispersion and load exists
When in bigger radius of turn, then the torsional forces of motor is bigger, and the power of motor is also bigger.
It is noted that when interior bucket is mounted with washing machine, with the increase of the load of interior bucket, the power of motor operation
Ascensional range is smaller, that is to say, that when the load of interior bucket is more, the trend of the rising for increasing the power for causing of interior bucket load compared with
For slow, and the power of motor eventually tends to a relatively stable peak power, and the peak power is interior bucket full load
Power.And work as and interior bucket is not installed in washing machine, when outer barrel is unloaded, the power of motor now is least work when outer barrel is unloaded
Rate, i.e. the first power, peak power of first power more than interior bucket full load motor.
Therefore, whether it is reference power with the first power in the present embodiment, it is only necessary to judge mean power more than the first work(
Rate, you can judge whether be mounted with interior bucket in washing machine, when mean power is more than the first power, be also greater than interior bucket full load
Peak power, it can be determined that do not install interior bucket in washing machine now, and then can accurately obtain program for washing.
In a further embodiment, the reference power is the power of motor described in interior bucket full load, and the power is herein
In be referred to as the second power, i.e. the reference power is the second power of motor described in interior bucket full load；Also can be regarded as interior bucket expires
The power of the motor is the second power during load.
In the present embodiment, when washing machine is mounted with interior bucket, during interior bucket full-load run, the corresponding peak power of motor is the
Two power, using second power as reference power.It is noted that under the same conditions, load is bigger, then the work(of motor
Rate is bigger.The same terms are referred in the case where interior bucket is mounted with, the power of motor is with the increase of the load of interior bucket
Increase, in the case where interior bucket is not installed, the power of motor increases with the increase of the load of outer barrel.At different conditions,
For example, the minimum power of outer barrel zero load when not installing interior bucket, more than the peak power of interior bucket full load, that is, the first power
More than the second power.
In the present embodiment, using second power as reference power, when mean power is more than the second power, then show laundry
Interior bucket is not installed in machine, when mean power is less than the second power, then shows to be mounted with interior bucket in washing machine, sentenced by above-mentioned
It is disconnected, and then can accurately obtain program for washing.
In order to further improve the accuracy of judged result, in one embodiment, the reference power is less than in outer barrel
Do not place interior bucket, and when unloaded the motor the first power, and more than the second power of motor described in interior bucket full load.
In the present embodiment, when washing machine does not install interior bucket, outer barrel no-load running, the corresponding power of motor is the first work(
Rate, when washing machine is mounted with interior bucket, during interior bucket full-load run, the corresponding peak power of motor is the second power, reference power
Between the first power and the second power.For example, with the median of the first power and the second power be reference power, and for example,
Average value with the first power and the second power is reference power, due to there may be error in the power for obtaining motor, and
First power of the washing machine of different model may be different, and the second power be likely to it is different, therefore, in order to reduce error, with
A power between first power and the second power can effectively reduce error as reference power, and then cause to refer to work(
The reference basis for estimation of rate is more accurate so that the program for washing of acquisition and laundry are currently installed on interior bucket whether state more
Match somebody with somebody.
For example, control method for washing machine also includes：
First stagefrequency obtaining step：Obtain the first stagefrequency.
Default inflow obtaining step：Default inflow is obtained, control water intaking valve is intake according to the default inflow.
Frequency variation obtaining step：The second stagefrequency after water inlet is obtained, according to first stagefrequency and institute
State the second stagefrequency and calculate acquisition frequency variation.
Variable quantity contrasts step：Whether the frequency variation is judged more than default variable quantity, is then to obtain second to do washing
Program, otherwise, obtains the first program for washing.
Program for washing determines step：Judge what is obtained respectively in power contrast's step and the variable quantity contrast step
Whether program for washing is same program, is to determine the program for washing, otherwise returns to actuating motor and rotates rate-determining steps.
Program for washing is obtained in order to further accurate, in one embodiment, as shown in Fig. 2 control method for washing machine is also
Including：
Step 210, obtains the first stagefrequency.
Specifically, stagefrequency is used to calculate the water level of washing machine, for example, stagefrequency is used to calculate outer barrel of washing machine
Water level, stagefrequency is obtained using level sensor, and the level sensor includes oscillating circuit, and oscillating circuit is in different hydraulic pressure
There is down different frequencies of oscillation, the frequency of oscillation according to oscillating circuit can obtain corresponding hydraulic pressure, so as to calculate laundry
Water level in machine outer barrel.
In the present embodiment, after washing machine startup, before washing, detection obtains the first stagefrequency, and then obtains laundry
The outer barrel of machine water level now.
Step 230, obtains default inflow, and control water intaking valve is intake according to the default inflow.
For example, inflow is detected using flow meter modules, for example, the inflow of water intaking valve is detected using flow meter modules,
The default inflow is default a certain amount of water, for example, the default inflow is 5 liters, and for example, the default inflow is 10
Rise.In the present embodiment, default inflow is obtained, control water intaking valve opens water inlet, and the amount of water inlet is default inflow.
Step 250, obtains the second stagefrequency after water inlet, according to first stagefrequency and second water level frequently
Rate is calculated and obtains frequency variation.
In this step, after water intaking valve opens water inlet, the water level in outer barrel rises, and obtains the second water level after water level rises
Frequency, that is, get the water level after rising.Calculated according to the first stagefrequency and the second stagefrequency and obtain frequency variation, example
Such as, the difference according to the first stagefrequency and the second stagefrequency calculates frequency variation, so as to get the ascending amount of water level.
Step 270, judges that whether the frequency variation, more than default variable quantity, is then to perform step 280, otherwise performs
Step 290.
For example, the default variable quantity is when not placing interior bucket in outer barrel, and the default inflow is pressed during outer barrel zero load
The frequency variation of the water level after water inlet.
Specifically, it is washing machine when not installing interior bucket to preset variable quantity, and under empty barrel state, inflow is preset in injection to outer barrel
Afterwards, the variable quantity of stagefrequency, the i.e. default variable quantity are the variable quantity of stagefrequency.Specifically, due to stagefrequency and water
Position is into positive correlation functional relation, i.e. the variable quantity of stagefrequency and the variable quantity of water level into positive correlation functional relation, so, water
The variable quantity of position is bigger, then the variable quantity of stagefrequency is bigger.After being mounted with interior bucket, the cross-sectional area of outer barrel reduces, therefore, note
Enter the water of same volume, the ascending amount of the water level of outer barrel when being mounted with interior bucket is greater than the water level of the outer barrel for not installing interior bucket
Ascending amount.
Therefore, after contrasting the default inflow of injection, whether the frequency variation of the water level of outer barrel is more than pre- for this step
If variable quantity, so as to judge that whether interior bucket is installed, and then different program for washing are obtained.
Step 280, obtains the second program for washing.
Step 290, obtains the first program for washing.
In the present embodiment, first program for washing is outer barrel program for washing, and second program for washing is interior bucket program for washing.
I.e. toward after the default inflow of injection in outer barrel, the frequency variation of outer barrel is more than in default variable quantity, i.e. outer barrel and is mounted with interior bucket,
Therefore, bucket washs corresponding second program for washing in obtaining, conversely, then obtaining outer barrel washs corresponding first program for washing.
Step 310, judges to judge whether the program for washing for obtaining is same program, is respectively in step 160 and step 270
Step 330 is then performed, step 350 is otherwise performed.
For example, whether the step of being performed after the step of being performed after judging step 160 and step 270 be identical, i.e., whether obtain
Same program for washing.For example, judge whether step 160 is identical with the judged result of step 270, and it is identical, then perform step
330, otherwise, return and perform step 120.
Step 330, determines the program for washing.
For example, the step of being performed after step 160 is identical with the step of execution after step 270, it is determined that held after step 160
Program for washing in capable step is the program for washing of output or the program for washing of execution.
For example, performing step 170 after step 160, step 290 is performed after step 270, judge that obtaining first does washing twice
Program, it is determined that the first program for washing is the program for washing of output or the program for washing of execution.For example, performing step after step 160
Rapid 180, step 280 is performed after step 270, judge to obtain the second program for washing twice, it is determined that the second program for washing is defeated
The program for washing or the program for washing of execution for going out.
Specifically, when judged result twice is identical, it is determined that the program for washing that judged result is obtained twice is washing for output
Clothing program, or determine that the program for washing that judged result is obtained twice is the program for washing for performing.Due to by detecting motor work(
Rate judges whether washing machine installs interior bucket, and judges whether washing machine installs interior bucket with reference to water level ascending amount so that judge knot
Fruit is more accurate, can be prevented effectively from error.
In this step, when judged result is different twice, then possible any judged result is wrong, then need to detect again and sentence
It is disconnected.In the present embodiment, return and perform step 120, controlled motor is rotated several times, and perform step 140 to step successively again
160, whether interior bucket is detected again is mounted with to washing machine, so as to avoid error.
It is noted that in the present embodiment, step 120 and step 210 can be carried out synchronously, can first carry out step
120 to step 180, then perform step 210 to step 290；Can also first carry out step 210 to step 290, then perform step
120 to step 180.In the present embodiment, contrast judgement is carried out by mean power respectively according to motor and reference power, according to
The frequency variation of outer barrel carries out contrast judgement with default variable quantity, with reference to judged result so that it is determined that program for washing, further
The accuracy of judgement is effectively increased, so that the clean result of program for washing is more preferably.
In order to be in the suds, the inflow of precise control washing machine, in one embodiment, in first program for washing
In, the testing result control inflow according to level sensor.For example, in second program for washing, according to flowmeter mould
The testing result control inflow of block.Specifically, it is used to detect the water level of outer barrel due to the level sensor, therefore, in outer barrel
Under washing mode, that is, under the first program for washing, the water level of outer barrel is detected using level sensor, and then according to detecting
The water level of outer barrel, controls the unlatching of water intaking valve, so as to realize controlling inflow.
And under interior bucket washing mode, that is, under the second program for washing, level sensor cannot accurately obtain interior bucket
Water, therefore, under the second program for washing, using flow meter modules, the inflow of water intaking valve is calculated, so as to calculate interior bucket
Water, and then the water level of interior bucket is got, and the opening and closing of water intaking valve are controlled with this, so as to realize the control of interior bucket inflow
