The embodiment of the present invention provides the fuzzy Weighing method of one and rotary drum washing machine, owing to have employed above technical scheme, has the advantage that
(1) if the motor of described rotary drum washing machine is external rotor electric machine, when described rotary drum washing machine is when weighing to the medicated clothing in rotary drum washing machine, power firstly the need of the motor for described rotary drum washing machine, the impeller making rotary drum washing machine described in described driven by motor accelerates to rotate to the first specified rotary speed, then turn off and power for described motor, described motor and described impeller is made to be simultaneously in moderating process, obtain the first rotary speed of described impeller, the moderating process that described first rotary speed is described impeller continues the rotary speed of described impeller after the first preset duration, described first rotary speed is not zero, and then according to described first rotary speed, determine the weight of medicated clothing in described rotary drum washing machine.The rotor of described external rotor electric machine is outside, and the quality of described rotor is bigger, the rotary inertia making external rotor electric machine is bigger, therefore when driven by motor impeller rotates, motor is bigger with the rotary inertia of impeller, the moderating process of described impeller can last longer, it is possible to by impeller from the first specified rotary speed slow down the first preset duration after the first rotary speed determine the weight of medicated clothing.Compared to prior art, described rotary drum washing machine is when weighing to the medicated clothing in rotary drum washing machine, need not experience impeller from the first specified rotary speed continued deceleration to speed is the process of zero, need only to impeller reduce speed now from the first specified rotary speed, this moderating process continues the first preset duration, the first rotary speed got after first preset duration is not zero, that is the first preset duration is decelerated to speed less than impeller from the first specified rotary speed is the time used by zero, thus having saved the time that described rotary drum washing machine determines the weight of washing medicated clothing, and then the time of laundry every time can be shortened.
(2) if when the motor of described rotary drum washing machine is inner rotor motor, when described rotary drum washing machine is when weighing to the medicated clothing in rotary drum washing machine, power firstly the need of the motor for described rotary drum washing machine, make the impeller of rotary drum washing machine described in described driven by motor accelerate with washing tub to rotate to the first specified rotary speed simultaneously, then turn off and power for described motor, make described motor, described impeller and described washing tub are simultaneously in moderating process, obtain the 3rd rotary speed of described impeller and described washing tub, described 3rd rotary speed is described impeller and the moderating process of washing tub continues the rotary speed of described impeller and washing tub after the first preset duration, 3rd rotary speed is not zero, and then according to described 3rd rotary speed, determine the weight of medicated clothing in described rotary drum washing machine.The rotor of described inner rotor motor is at center, the rotary inertia making described inner rotor motor is less, when inner rotor motor drives the impeller of described rotary drum washing machine to rotate by belt transmission, motor is less with the rotary inertia of impeller, if simply impeller rotates, the time that impeller is decelerated to zero from the first specified rotary speed is very short, when there is medicated clothing in described rotary drum washing machine, due to the friction effects between medicated clothing and impeller, the time that impeller is decelerated to zero from the first specified rotary speed is shorter, therefore the weight of medicated clothing cannot be obtained by obtaining the impeller rotary speed after the first preset duration of slowing down.If so the motor of rotary drum washing machine is inner rotor motor, when the medicated clothing in rotary drum washing machine being carried out fuzzy weighing, can so that impeller and washing tub rotate simultaneously, rotary inertia is bigger, and medicated clothing can be followed washing tub and be rotated together, centrifugal force when medicated clothing rotates further increases rotary inertia, extend the deceleration time of described impeller and washing tub, therefore, it is possible to determine the weight of medicated clothing by impeller and washing tub from the 3rd rotary speed after the first specified rotary speed is decelerated to the first preset duration.Compared to prior art, described rotary drum washing machine is when weighing to the medicated clothing in rotary drum washing machine, need not experience impeller and washing tub simultaneously from the first specified rotary speed continued deceleration to speed be the process of zero, need only to impeller and washing tub reduces speed now from the first specified rotary speed simultaneously, this moderating process continues the first preset duration, the 3rd rotary speed got after first preset duration is not zero, that is the first preset duration is decelerated to speed from the first specified rotary speed less than impeller and washing tub simultaneously is the time used by zero, thus having saved the time that described rotary drum washing machine determines the weight of washing medicated clothing, and then the time of laundry every time can be shortened.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
The embodiment of the present invention provides the fuzzy Weighing method of a kind of rotary drum washing machine, as it is shown in figure 1, for rotary drum washing machine, the motor of described rotary drum washing machine is external rotor electric machine, and described fuzzy Weighing method includes:
The impeller of rotary drum washing machine described in step 101, described driven by motor accelerates to rotate to the first specified rotary speed.
Concrete, described rotary drum washing machine can be powered by the motor that control circuit is described rotary drum washing machine, and then control the acceleration rotation of described external rotor electric machine, the impeller driving described rotary drum washing machine rotates to the first specified rotary speed, described first specified rotary speed is set in advance, can being set according to the concrete condition of rotary drum washing machine in practical application, this is not limited by the embodiment of the present invention.
Preferably, can after described impeller acceleration rotation to the first specified rotary speed, described impeller is made to continue to rotate with the first specified rotary speed in the second preset duration, described second preset duration is set in advance, can being configured according to the concrete condition of rotary drum washing machine in practical application, this is not limited by the embodiment of the present invention.
Step 102, described motor and described impeller are simultaneously in moderating process, obtain the first rotary speed of described impeller, the moderating process that described first rotary speed is described impeller continues the rotary speed of described impeller after the first preset duration, and described first rotary speed is not zero.
It is the rotary drum washing machine of external rotor electric machine for motor, when the impeller of described rotary drum washing machine rotates to after the first specified rotary speed, described rotary drum washing machine can stop powering for described external rotor electric machine, now described impeller is in deceleration regime, then the first rotary speed of described impeller is obtained, the moderating process that described first rotary speed is described impeller continues the rotary speed of described impeller after the first preset duration, and described first rotary speed is not zero.
Optionally, being the rotary drum washing machine of external rotor electric machine for motor, the rotary speed of impeller is equal with the rotating speed of motor, it is possible to determined the rotary speed of impeller by the rotating speed of motor.Example, described motor can configure Hall element, motor for every revolution, Hall element 12 pulses of output, and then described rotary drum washing machine can obtain the rotating speed of motor by the umber of pulse that Hall element per second exports.Concrete, the the first specified rotary speed assuming impeller is 100 revolutions per seconds, corresponding umber of pulse is 1200 pulses each second, namely when rotary drum washing machine detects that Hall element exports 1200 pulses each second, represent that impeller has reached the first specified rotary speed, timer starts timing, stop powering for motor simultaneously, motor and impeller is made to be simultaneously in free moderating process, when the time of timer reaches the first preset duration, the umber of pulse of rotary drum washing machine detection Hall element output, then pass through described umber of pulse and obtain impeller rotary speed now as the first rotary speed.In practical application, rotary drum washing machine can also determine the rotating speed of motor by the change frequency of the electromotive force that motor exports, or arranges lenticular lenses on motor, is determined the rotating speed of motor by raster count.
Wherein, described first preset duration is set in advance, it is possible to being configured according to the concrete condition of rotary drum washing machine, this is not limited by the embodiment of the present invention.
Preferably, it is the rotary drum washing machine of external rotor electric machine for motor, the impeller that can work as described rotary drum washing machine continues with after the first specified rotary speed rotation in the second preset duration, stop powering for described external rotor electric machine, make described motor and described impeller be simultaneously in moderating process, and obtain the first rotary speed of described impeller.
Step 103, according to described first rotary speed, it is determined that the weight of medicated clothing in described rotary drum washing machine.
Owing to the motor of described rotary drum washing machine is external rotor electric machine, so the impeller of rotary drum washing machine and external rotor electric machine are coaxial rotation, the rotor of external rotor electric machine is outside, and the quality of described rotor is bigger, the rotary inertia making external rotor electric machine is bigger, therefore when driven by motor impeller rotates, motor is bigger with the rotary inertia of impeller, the moderating process of described impeller can last longer, it is possible to by impeller from the first specified rotary speed slow down the first preset duration after the first rotary speed determine the weight of medicated clothing.
When the medicated clothing in rotary drum washing machine is more, frictional force between described medicated clothing and impeller is bigger, under the impact of described bigger frictional force, the first rotary speed that described impeller obtains after slowing down the first preset duration from the first specified rotary speed is less, now the first preset duration needs to arrange shorter duration, it is possible to by impeller from the first specified rotary speed slow down the first preset duration after the first rotary speed determine the weight of medicated clothing.When the medicated clothing in rotary drum washing machine is less, frictional force between described medicated clothing and impeller is less, under the impact of described less frictional force, the first rotary speed that described impeller obtains after slowing down the first preset duration from the first specified rotary speed is bigger, although this is the first preset duration can arrange longer duration, if but the first preset duration setting is longer, when the medicated clothing in rotary drum washing machine is more, being likely in the first preset duration impeller stops the rotation, the first rotary speed cannot be obtained, therefore, need during initialization to be that the first preset duration arranges shorter duration, can by impeller from the first specified rotary speed slow down the first preset duration after the first rotary speed determine the weight of medicated clothing.When the first preset duration arranges applicable, so the weight of the medicated clothing in rotary drum washing machine and described first rotary speed are inversely proportional to.
Optionally, rotary speed table corresponding to clothes weight can be prestored in the control chip of rotary drum washing machine, the clothes weight that rotary speed that described rotary speed is different from the corresponding table record of clothes weight is corresponding respectively, then according to the first rotary speed, the rotary speed table corresponding to clothes weight that prestore of inquiry, namely can determine that the weight of medicated clothing in rotary drum washing machine.
In practical application, acceleration table corresponding to clothes weight can also be prestored, described acceleration is corresponding from the corresponding table of clothes weight, and different acceleration distinguishes corresponding clothes weight, after getting described first rotary speed, according to the corresponding relation between rotary speed and acceleration, the first acceleration that described first rotary speed is corresponding can be obtained, then according to the first acceleration, the acceleration table corresponding to clothes weight that inquiry prestores, namely can determine that the weight of described medicated clothing.
So, it is external rotor electric machine at rotary drum washing machine motor, and rotary drum washing machine is when weighing to medicated clothing, described rotary drum washing machine can first pass through the motor that control circuit is described rotary drum washing machine and power, the impeller making rotary drum washing machine described in described driven by motor rotates to the first specified rotary speed, after reaching the first specified rotary speed, stop powering for described motor, described motor and described impeller is made to be simultaneously in moderating process, then the first rotary speed of described impeller is obtained, the moderating process that described first rotary speed is described impeller continues the rotary speed of described impeller after the first preset duration, described first rotary speed is not zero, may finally according to described first rotary speed, determine the weight of medicated clothing in described rotary drum washing machine.Compared to prior art, fuzzy Weighing method described in the embodiment of the present invention, need not experience impeller from the first specified rotary speed continued deceleration to speed is the process of zero, need only to impeller reduce speed now from the first specified rotary speed, this moderating process continues the first preset duration, the first rotary speed got after first preset duration is not zero, that is the first preset duration is decelerated to speed less than impeller from the first specified rotary speed is the time used by zero, thus having saved the time that described rotary drum washing machine determines the weight of washing medicated clothing, and then the time of laundry every time can be shortened.
Further, the impeller at rotary drum washing machine described in described driven by motor accelerates to rotate to after the first specified rotary speed, and described motor can also drive described impeller to continue to rotate with described first specified rotary speed in the second preset duration.Example, it is that described motor is powered that rotary drum washing machine can also continue to by control circuit, impeller described in described driven by motor is made to continue to rotate with described first specified rotary speed in the second preset duration, so can so that the rotary speed of impeller of rotary drum washing machine stable maintain the first specified rotary speed, it is to avoid owing to the speed of described impeller is unstable and reduce the accuracy of described fuzzy Weighing method.
Optionally, described according to described first rotary speed, determine in described rotary drum washing machine before the weight of medicated clothing, described rotary drum washing machine can also obtain the second rotary speed, when described second rotary speed is be absent from medicated clothing in described rotary drum washing machine, described impeller from after the first preset duration described in the first specified rotary speed continued deceleration, the rotary speed of described impeller, then can according to the difference of described first rotary speed Yu described second rotary speed, it is determined that the weight of described medicated clothing；Or the ratio according to described first rotary speed Yu described second rotary speed, it is determined that the weight of described medicated clothing.In actual applications, if rotary drum washing machine uses the time longer, can cause that loss is comparatively serious, make the frictional force within rotary drum washing machine bigger, now, if determining the weight of medicated clothing in rotary drum washing machine only by the first rotary speed, described first rotary speed includes the velocity variations that a part is caused by rotary drum washing machine internal factor, make the clothes weight actual weight more than medicated clothing of acquisition, the weight of medicated clothing is determined according to the difference of described first rotary speed Yu described second rotary speed, then can get rid of the impact owing to rotary drum washing machine factor causes.The same ratio adopting described first rotary speed and described second rotary speed, it is determined that the weight of described medicated clothing, it is also possible to get rid of the impact owing to rotary drum washing machine factor causes.
In practical application, before rotary drum washing machine dispatches from the factory, it is possible to the second rotary speed is pre-stored in the control chip of rotary drum washing machine, when medicated clothing is carried out fuzzy weighing by rotary drum washing machine, it is possible to directly obtain the second rotary speed from described control chip.Concretely comprising the following steps of the second rotary speed is obtained: when being absent from medicated clothing in the washing tub of described rotary drum washing machine during initialization, motor for rotary drum washing machine is powered, impeller described in described driven by motor is rotated to described first specified rotary speed, then turn off and power for described motor, make described motor and described impeller be simultaneously in moderating process, obtain the moderating process of described impeller and continue after the first preset duration the rotary speed of described impeller as the second rotary speed.
When rotary drum washing machine uses the time longer, when wearing and tearing bigger, user can also redeterminate the second rotary speed according to the concrete steps obtaining the second rotary speed, obtain the second new rotary speed, then more it is newly stored in the second rotary speed in control chip by described the second new rotary speed, improves the accuracy of the fuzzy Weighing method of rotary drum washing machine.
Optionally, difference according to described first rotary speed Yu described second rotary speed, when determining the weight of described medicated clothing, the rotary speed difference that can prestore in the control chip of described rotary drum washing machine table corresponding to clothes weight, the clothes weight that rotary speed difference that described rotary speed difference is different from the corresponding table record of clothes weight is corresponding respectively, then can according to the difference of described first rotary speed Yu described second rotary speed, by inquiring about the rotary speed difference table corresponding to clothes weight prestored, namely can determine that the weight of described medicated clothing.
Optionally, ratio according to described first rotary speed Yu described second rotary speed, when determining the weight of described medicated clothing, can be prestored rotary speed ratio table corresponding to clothes weight in the control chip of described rotary drum washing machine, the clothes weight that the rotary speed ratio different from the corresponding table record of clothes weight of described rotary speed ratio is corresponding respectively, then can according to the ratio of described first rotary speed Yu described second rotary speed, by inquiring about the rotary speed ratio table corresponding to clothes weight prestored, namely can determine that the weight of described medicated clothing.
The fuzzy Weighing method that the embodiment of the present invention provides, when medicated clothing is weighed by the rotary drum washing machine that motor is external rotor electric machine, the motor that control circuit is described rotary drum washing machine can be first passed through power, the impeller making rotary drum washing machine described in described driven by motor rotates to the first specified rotary speed, after reaching the first specified rotary speed, stop powering for described motor, described motor and described impeller is made to be simultaneously in moderating process, then the first rotary speed of described impeller is obtained, the moderating process that described first rotary speed is described impeller continues the rotary speed of described impeller after the first preset duration, described first rotary speed is all not zero, may finally according to described first rotary speed, determine the weight of medicated clothing in described rotary drum washing machine.Or obtain when there is no medicated clothing in rotary drum washing machine described impeller from after the first preset duration described in the first specified rotary speed continued deceleration, second rotary speed of described impeller, then according to the difference of the first rotary speed and the second rotary speed or ratio, it is determined that the weight of medicated clothing in described rotary drum washing machine.Compared to prior art, fuzzy Weighing method described in the embodiment of the present invention, need not experience impeller from the first specified rotary speed continued deceleration to speed is the process of zero, need only to impeller reduce speed now from the first specified rotary speed, this moderating process continues the first preset duration, the first rotary speed got after first preset duration is not zero, that is the first preset duration is decelerated to speed less than impeller from the first specified rotary speed is the time used by zero, thus having saved the time that described rotary drum washing machine determines the weight of washing medicated clothing, and then the time of laundry every time can be shortened.Further, owing to described rotary drum washing machine can also according to first rotary speed difference with the second rotary speed or ratio, determine the weight of medicated clothing in described rotary drum washing machine, it is possible to get rid of the impact owing to rotary drum washing machine factor causes, improve the accuracy of described fuzzy Weighing method.

The embodiment of the present invention provides the fuzzy Weighing method of a kind of rotary drum washing machine, as it is shown on figure 3, for rotary drum washing machine, the motor of described rotary drum washing machine is inner rotor motor, and described fuzzy Weighing method includes:
The impeller of rotary drum washing machine described in step 301, described driven by motor accelerates with washing tub to rotate to the second specified rotary speed simultaneously.
Concrete, described rotary drum washing machine can be that described inner rotor motor is powered by control circuit, the impeller of rotary drum washing machine described in described driven by motor and washing tub are rotated to described second specified rotary speed simultaneously, described second specified rotary speed is set in advance, can being set according to the concrete condition of rotary drum washing machine in practical application, this is not limited by the embodiment of the present invention.
Preferably, can accelerate to rotate to after the second specified rotary speed at described impeller and described washing tub simultaneously, make described impeller continue with described washing tub to rotate with the second specified rotary speed in the 3rd preset duration simultaneously, described 3rd preset duration is set in advance, can being configured according to the concrete condition of rotary drum washing machine in practical application, this is not limited by the embodiment of the present invention.
Step 302, described motor, described impeller and described washing tub are simultaneously in moderating process, obtain the 3rd rotary speed of described impeller and described washing tub, described 3rd rotary speed is described impeller and the moderating process of washing tub continues the rotary speed of described impeller and washing tub after the second preset duration, and the 3rd rotary speed is not zero.
It is the rotary drum washing machine of inner rotor motor for motor, when described impeller and described washing tub rotate to after the second specified rotary speed simultaneously, described rotary drum washing machine can stop powering for described inner rotor motor by control circuit, now described motor, described impeller and described washing tub are simultaneously in deceleration regime, then the 3rd rotary speed of described impeller and described washing tub is obtained, described 3rd rotary speed is described impeller and the moderating process of washing tub continues the rotary speed of described impeller and washing tub after described second preset duration, described 3rd rotary speed is not zero.
Optionally, it is the rotary drum washing machine of inner rotor motor for motor, motor drives impeller and washing tub to rotate by belt transmission simultaneously, and the rotary speed of impeller is equal to the rotating speed of motor or proportional, it is possible to determined the rotary speed of impeller and washing tub by the rotating speed of motor.Example, described motor can configure Hall element, motor for every revolution, Hall element 12 pulses of output, and then described rotary drum washing machine can obtain the rotating speed of motor by the umber of pulse that Hall element per second exports.Concrete, assume that the rotating speed of motor becomes 1:2 with the rotary speed of impeller and washing tub, second specified rotary speed of impeller and washing tub is 100 revolutions per seconds, corresponding umber of pulse is 600 pulses each second, when rotary drum washing machine detects that the pulse that Hall element exports reaches each second 600, represent that the rotary speed of impeller and washing tub has reached the second specified rotary speed, this hour counter starts timing, and stop powering for motor, make described motor, described impeller and described washing tub are simultaneously in moderating process, when the time of timer record reaches the second preset duration, the umber of pulse of detection Hall element output each second, impeller is obtained with washing machine rotary speed now as the 3rd rotary speed by described umber of pulse.In practical application, rotary drum washing machine can also determine the rotating speed of motor by the change frequency of the electromotive force that motor exports, or arranges lenticular lenses on motor, is determined the rotating speed of motor by raster count.
Wherein, described second preset duration is set in advance, it is possible to being configured according to the concrete condition of rotary drum washing machine, this is not limited by the embodiment of the present invention.
Preferably, it is the rotary drum washing machine of inner rotor motor for motor, after the impeller of described rotary drum washing machine and washing tub continue to rotate with the second specified rotary speed in the 3rd preset duration, stop the inner rotor motor for described rotary drum washing machine to power, what make to state impeller and washing tub is simultaneously in moderating process, and obtains the 3rd rotary speed of described impeller and described washing tub.
Step 303, according to described 3rd rotary speed, it is determined that the weight of medicated clothing in described rotary drum washing machine.
Owing to the motor of described rotary drum washing machine is inner rotor motor, so needing belt transmission between the impeller of rotary drum washing machine and inner rotor motor, the rotor of inner rotor motor is at center, the rotary inertia making described inner rotor motor is less, when the impeller that inner rotor motor drives described rotary drum washing machine rotates, motor is less with the rotary inertia of impeller, if simply impeller rotates, the time that impeller is decelerated to zero from the second specified rotary speed is very short, when there is medicated clothing in described rotary drum washing machine, due to the friction effects between medicated clothing and impeller, the time that impeller is decelerated to zero from the second specified rotary speed is shorter, therefore the weight of medicated clothing cannot be obtained by obtaining the impeller rotary speed after the second preset duration of slowing down.If so the motor of rotary drum washing machine is inner rotor motor, when the medicated clothing in rotary drum washing machine being carried out fuzzy weighing, can so that impeller and washing tub rotate simultaneously, rotary inertia is bigger, and medicated clothing can be followed washing tub and be rotated together, centrifugal force when medicated clothing rotates further increases rotary inertia, extend the deceleration time of described impeller and washing tub, therefore, it is possible to determine the weight of medicated clothing by impeller and washing tub from the 3rd rotary speed after the second specified rotary speed is decelerated to the second preset duration.
When the medicated clothing in rotary drum washing machine is more, the rotary inertia of impeller, washing tub and medicated clothing is relatively big, therefore described impeller and washing tub from the second specified rotary speed slow down the second preset duration after the 3rd rotary speed bigger；When the medicated clothing in rotary drum washing machine is less, the rotary inertia of impeller, washing tub and medicated clothing is less, therefore described impeller and washing tub from the second specified rotary speed slow down the second preset duration after the 3rd rotary speed less, so the weight of the medicated clothing in rotary drum washing machine was directly proportional to the described very first time.
Optionally, rotary speed table corresponding to clothes weight can be prestored in the control chip of rotary drum washing machine, the clothes weight that rotary speed that described rotary speed is different from the corresponding table record of clothes weight is corresponding respectively, then according to the 3rd rotary speed, the rotary speed table corresponding to clothes weight that prestore of inquiry, namely can determine that the weight of medicated clothing in rotary drum washing machine.
In practical application, acceleration table corresponding to clothes weight can also be prestored in the control chip of rotary drum washing machine, described acceleration is corresponding from the corresponding table of clothes weight, and different acceleration distinguishes corresponding clothes weight, after getting the 3rd rotary speed, can according to the corresponding relation between rotary speed and acceleration, obtain the second acceleration that described 3rd rotary speed is corresponding, then according to the second acceleration, inquiry acceleration table corresponding to clothes weight, namely can determine that the weight of described medicated clothing.
So, it is external rotor electric machine at rotary drum washing machine motor, and rotary drum washing machine is when weighing to medicated clothing, it is that motor is powered that described rotary drum washing machine can first pass through control circuit, make impeller described in described driven by motor accelerate with described washing tub to rotate to described second specified rotary speed simultaneously, after reaching the second specified rotary speed, stop powering for described motor, described impeller and described washing tub is made to be in moderating process, obtain the 3rd rotary speed of described impeller and described washing tub, described 3rd rotary speed is described impeller and the moderating process of washing tub continues the rotary speed of described impeller and washing tub after described second preset duration, described 3rd rotary speed is not zero, may finally according to described 3rd rotary speed, determine the weight of medicated clothing in described rotary drum washing machine.Compared to prior art, fuzzy Weighing method described in the embodiment of the present invention, need not experience impeller and washing tub simultaneously from the second specified rotary speed continued deceleration to speed be the process of zero, need only to impeller and rotary drum washing machine reduces speed now from the second specified rotary speed simultaneously, this moderating process continues the second preset duration, the first rotary speed got after second preset duration is not zero, that is the second preset duration is decelerated to speed from the second specified rotary speed less than impeller and washing tub simultaneously is the time used by zero, thus having saved the time that described rotary drum washing machine determines the weight of washing medicated clothing, and then the time of laundry every time can be shortened.
Further, power at the motor for described rotary drum washing machine, the washing tub making impeller described in described driven by motor and described rotary drum washing machine accelerates to rotate to after the second specified rotary speed simultaneously, and described motor can also drive described impeller to continue with described washing tub to rotate with described second specified rotary speed in described 3rd preset duration simultaneously.Example, rotary drum washing machine can also continue to power for described motor, impeller described in described driven by motor and washing tub is made to continue to rotate with described second specified rotary speed in the 3rd preset duration, so can so that the impeller of rotary drum washing machine and the rotary speed of washing tub stable maintain the second specified rotary speed, it is to avoid owing to the speed of described impeller and washing tub is unstable and reduce the accuracy of described fuzzy Weighing method.
Optionally, described according to described 3rd rotary speed, determine in described rotary drum washing machine before the weight of medicated clothing, described rotary drum washing machine can also obtain the 4th rotary speed, when described 4th rotary speed is be absent from medicated clothing in described rotary drum washing machine, described impeller and washing tub are from the rotary speed of described impeller after the second preset duration described in the second specified rotary speed continued deceleration with washing tub, then can according to the difference of described 3rd rotary speed Yu described 4th rotary speed, it is determined that the weight of described medicated clothing；Or the ratio according to described 3rd rotary speed Yu described 4th rotary speed, it is determined that the weight of described medicated clothing.In actual applications, if rotary drum washing machine uses the time longer, can cause that loss is comparatively serious, make the frictional force within rotary drum washing machine bigger, now, if the 3rd rotary speed only by impeller Yu washing tub determines the weight of medicated clothing in rotary drum washing machine, the clothes weight actual weight more than medicated clothing of acquisition can be made, determine the weight of medicated clothing according to the difference of described 3rd rotary speed Yu described 4th rotary speed, then can get rid of the impact owing to rotary drum washing machine factor causes.The same ratio adopting described 3rd rotary speed and described 4th rotary speed, it is determined that the weight of described medicated clothing, it is also possible to get rid of the impact owing to rotary drum washing machine factor causes.
In practical application, before rotary drum washing machine dispatches from the factory, it is possible to the 4th time was pre-stored in the control chip of rotary drum washing machine, when medicated clothing is carried out fuzzy weighing by rotary drum washing machine, it is possible to directly obtained for the 4th time from described control chip.
During initialization, obtain concretely comprising the following steps of the 4th rotary speed: when being absent from medicated clothing in the washing tub of described rotary drum washing machine, described rotary drum washing machine is that described motor is powered by control circuit, impeller described in described driven by motor and described washing tub are rotated to described second specified rotary speed simultaneously, then pass through control circuit to stop powering for described motor, make described motor, described impeller and described washing tub are simultaneously in moderating process, obtain the moderating process of described impeller and described washing tub and continue after described second preset duration the rotary speed of described impeller and washing tub as the 4th rotary speed.
Optionally, difference according to described 3rd rotary speed Yu described 4th rotary speed, when determining the weight of described medicated clothing, the rotary speed difference that can prestore in the control chip of described rotary drum washing machine table corresponding to clothes weight, the clothes weight that rotary speed difference that described rotary speed difference is different from the corresponding table record of clothes weight is corresponding respectively, then can according to the difference of described 3rd rotary speed Yu described 4th rotary speed, by inquiring about the rotary speed difference table corresponding to clothes weight prestored, namely can determine that the weight of described medicated clothing.
Optionally, ratio according to described 3rd rotary speed Yu described 4th rotary speed, when determining the weight of described medicated clothing, can be prestored rotary speed ratio table corresponding to clothes weight in the control chip of described rotary drum washing machine, the clothes weight that the rotary speed ratio different from the corresponding table record of clothes weight of described rotary speed ratio is corresponding respectively, then can according to the ratio of described 3rd rotary speed Yu described 4th rotary speed, by inquiring about the rotary speed ratio table corresponding to clothes weight prestored, namely can determine that the weight of described medicated clothing.
Optionally, at described motor, before described impeller and described washing tub are simultaneously in free moderating process, described rotary drum washing machine can also open the spraying of described rotary drum washing machine, spray water to the medicated clothing in described rotary drum washing machine, continue the 4th preset duration, increase the weight of medicated clothing, increase the rotary inertia of impeller and washing tub, at the rotary drum washing machine of inner rotor motor when medicated clothing is weighed, if rotary drum washing machine exists medicated clothing, rotate to while the second specified rotary speed at impeller and washing tub, medicated clothing also can be followed washing tub and be rotated to the second specified rotary speed, centrifugal force when medicated clothing rotates further increases the rotary inertia of impeller and washing tub, the rotary inertia of the more big increase of the weight of medicated clothing is more big.nullWhen the clothes weight in described rotary drum washing machine is less，Less by the rotary inertia that the weight of medicated clothing is impeller and washing tub increase，After the second preset duration，The impeller obtained and the 3rd rotary speed of washing tub are likely to little with described 4th rotary speed gap，Cannot according to the 3rd rotary speed difference with the 4th rotary speed or ratio，Obtain the accurate weight of medicated clothing，So before stopping powering for motor，Described rotary drum washing machine can be opened spraying and continue the 4th preset duration，Spray water to the medicated clothing in described rotary drum washing machine，Increase the frictional force between described medicated clothing and described washing tub，Then the 3rd rotary speed of impeller and washing tub is obtained，Described 3rd rotary speed is bigger with the gap of the second specified rotary speed，Can determine the weight of described medicated clothing，Then rotary drum washing machine is when Normal Wash，Flooding time is made to shorten described 4th preset duration，Determine water consumption during described clothes washing equally.
The fuzzy Weighing method that the embodiment of the present invention provides, when medicated clothing is weighed by the rotary drum washing machine that motor is inner rotor motor, the motor that control circuit is described rotary drum washing machine can be first passed through power, make impeller described in described driven by motor accelerate with described washing tub to rotate to described second specified rotary speed simultaneously, after reaching the second specified rotary speed, stop powering for described motor, described impeller and described washing tub is made to be in moderating process, obtain the 3rd rotary speed of described impeller and described washing tub, described 3rd rotary speed is described impeller and the moderating process of washing tub continues the rotary speed of described impeller and washing tub after described second preset duration, described 3rd rotary speed is not zero, may finally according to described 3rd rotary speed, determine the weight of medicated clothing in described rotary drum washing machine.Or obtain when there is no medicated clothing in rotary drum washing machine described impeller and washing tub from after the second preset duration described in the second specified rotary speed continued deceleration, 4th rotary speed of described impeller and washing tub, then according to the difference of the 3rd rotary speed and the 4th rotary speed or ratio, it is determined that the weight of medicated clothing in described rotary drum washing machine.Compared to prior art, fuzzy Weighing method described in the embodiment of the present invention, need not experience impeller and washing tub simultaneously from the second specified rotary speed continued deceleration to speed be the process of zero, need only to impeller and washing tub reduces speed now from the second specified rotary speed simultaneously, this moderating process continues the second preset duration, the 3rd rotary speed got after second preset duration is not zero, that is the second preset duration is decelerated to speed from the second specified rotary speed less than impeller and washing tub simultaneously is the time used by zero, thus having saved the time that described rotary drum washing machine determines the weight of washing medicated clothing, and then the time of laundry every time can be shortened.Further, owing to described rotary drum washing machine can also according to the 3rd rotary speed difference with the 4th rotary speed or ratio, determine the weight of medicated clothing in described rotary drum washing machine, it is possible to get rid of the impact owing to rotary drum washing machine factor causes, improve the accuracy of described fuzzy Weighing method.
The embodiment of the present invention provides a kind of rotary drum washing machine 40, and the motor of described rotary drum washing machine 40 is external rotor electric machine, and as shown in Figure 4, described rotary drum washing machine 40 includes control unit 401, acquiring unit 402 and determines unit 403.
Described control unit 401 is used for: control described motor so that the impeller of rotary drum washing machine 40 described in described driven by motor accelerates with washing tub to rotate to the second specified rotary speed simultaneously；Control described motor so that described motor, described impeller and described washing tub are simultaneously in moderating process.
Concrete, described rotary drum washing machine 40 can be powered by the motor that control circuit is described rotary drum washing machine 40, and then control the acceleration rotation of described inner rotor motor, the impeller and the washing tub that drive described rotary drum washing machine 40 rotate to the second specified rotary speed simultaneously, described second specified rotary speed is set in advance, can being configured according to the concrete condition of rotary drum washing machine 40, this is not limited by the embodiment of the present invention.Then can also stopping powering for described inner rotor motor by control circuit, now described motor, impeller and washing tub are in free deceleration regime.
Described acquiring unit 402, for obtaining the 3rd rotary speed of described impeller and described washing tub, described 3rd rotary speed is described impeller and the moderating process of washing tub continues the rotary speed of described impeller and washing tub after the second preset duration, and the 3rd rotary speed is not zero.
General, acquiring unit 402 can the timing when described moderating process starts, when described impeller and washing tub moderating process simultaneously stop timing when continuing the second preset duration, obtain the rotary speed of now impeller and washing tub as the 3rd rotary speed.
Optionally, it is the rotary drum washing machine of inner rotor motor for motor, motor drives impeller and washing tub to rotate by belt transmission simultaneously, and the rotary speed of impeller is equal to the rotating speed of motor or proportional, it is possible to determined the rotary speed of impeller and washing tub by the rotating speed of motor.Example, described motor can configure Hall element, motor for every revolution, Hall element 12 pulses of output, and then described rotary drum washing machine can obtain the rotating speed of motor by the umber of pulse that Hall element per second exports.Concrete, assume that the rotating speed of motor becomes 1:2 with the rotary speed of impeller and washing tub, second specified rotary speed of impeller and washing tub is 100 revolutions per seconds, corresponding umber of pulse is 600 pulses each second, when rotary drum washing machine detects that the pulse that Hall element exports reaches each second 600, represent that the rotary speed of impeller and washing tub has reached the second specified rotary speed, this hour counter starts timing, and stop powering for motor, make described motor, described impeller and described washing tub are simultaneously in moderating process, when the time of timer record reaches the second preset duration, acquiring unit 402 detects the umber of pulse of Hall element output each second, impeller is obtained with washing machine rotary speed now as the 3rd rotary speed by described umber of pulse.In practical application, acquiring unit 402 can also determine the rotating speed of motor by the change frequency of the electromotive force that motor exports, or arranges lenticular lenses on motor, is determined the rotating speed of motor by raster count.
Determine unit 403, for according to described 3rd rotary speed, it is determined that the weight of medicated clothing in described rotary drum washing machine 40.
Owing to the motor of described rotary drum washing machine 40 is inner rotor motor, so needing belt transmission between the impeller of rotary drum washing machine 40 and inner rotor motor, the rotor of inner rotor motor is at center, the rotary inertia making described inner rotor motor is less, when the impeller that inner rotor motor drives described rotary drum washing machine 40 rotates, motor is less with the rotary inertia of impeller, if simply impeller rotates, the time that impeller is decelerated to zero from the second specified rotary speed is very short, when there is medicated clothing in described rotary drum washing machine 40, due to the friction effects between medicated clothing and impeller, the time that impeller is decelerated to zero from the second specified rotary speed is shorter, therefore the weight of medicated clothing cannot be obtained by obtaining the impeller rotary speed after the second preset duration of slowing down.If so the motor of rotary drum washing machine 40 is inner rotor motor, when the medicated clothing in rotary drum washing machine being carried out fuzzy weighing, can so that impeller and washing tub rotate simultaneously, rotary inertia is bigger, and medicated clothing can be followed washing tub and be rotated together, centrifugal force when medicated clothing rotates further increases rotary inertia, extend the deceleration time of described impeller and washing tub, therefore, it is possible to determine the weight of medicated clothing by impeller and washing tub from the 3rd rotary speed after the second specified rotary speed is decelerated to the second preset duration.
When the medicated clothing in rotary drum washing machine 40 is more, the rotary inertia of impeller, washing tub and medicated clothing is relatively big, therefore described impeller and washing tub from the second specified rotary speed slow down the second preset duration after the 3rd rotary speed bigger；When the medicated clothing in rotary drum washing machine 40 is less, the rotary inertia of impeller, washing tub and medicated clothing is less, therefore described impeller and washing tub from the second specified rotary speed slow down the second preset duration after the 3rd rotary speed less, so the weight of the medicated clothing in rotary drum washing machine 40 was directly proportional to the described very first time.
