Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein.

Example one
The present application provides a shaking and dispersing method of a washing machine including a brake motor, as shown in fig. 1, the method may include:
and step S11, acquiring a real-time eccentricity value of the washing machine.
And step S13, determining the tub sticking condition of the washing machine according to the eccentricity value.
And step S15, controlling the washing machine to execute a common shaking and scattering strategy or a special shaking and scattering strategy according to the barrel sticking condition of the washing machine, wherein under the special shaking and scattering strategy, the brake motor rotates forwards or backwards.
Specifically, in the scheme, a controller or a processor of the washing machine can be used as an execution main body of the scheme, after the washing machine is finally taken off, the controller can obtain a real-time eccentric value of the washing machine according to a built-in weighing device of the washing machine, then the barrel attaching condition of clothes of the washing machine is determined according to the real-time eccentric value and a comparison result of a preset eccentric value, then a common shaking-off strategy or a special shaking-off strategy is selected to be executed according to the actual barrel attaching condition of the washing machine, it needs to be explained that under the special shaking-off strategy, the scheme can drive a brake motor of the washing machine to rotate forwards or reversely to shake off the clothes, namely in the special shaking-off strategy, the motor with a brake can be used, and the clothes are separated from the barrel wall of the washing machine by using inertia of a load during shaking-off, so that a better shaking-off effect is achieved.
It should be noted that, the preset eccentric value may be a normal eccentric value of the washing machine after the clothes of different weight levels are put into the washing machine, the clothes of different weight levels all correspond to different normal eccentric values or ranges, after the washing machine is finally taken off, the controller may obtain a real-time eccentric value of the washing machine according to a built-in weighing device of the washing machine, and then compare the real-time eccentric value with the preset eccentric value, if the deviation of the real-time eccentric value and the preset eccentric value is small, for example, the increase of the eccentric value is less than 10%, the scheme indicates that the clothes are stuck to the tub or the eccentric condition is light, if the deviation of the real-time eccentric value and the preset eccentric value is large, for example, the increase of the eccentric value is greater than 10%, the scheme indicates that the clothes are stuck to the tub or the eccentric condition is heavy, and the scheme employs a special shaking strategy.
According to the technical scheme, the shaking and scattering method is different from the shaking and scattering method which is fixed and preset in execution in the prior art, the shaking and scattering strategy can be determined to be executed according to the self-adaption of the condition of the clothes attached to the barrel in the washing machine barrel, the shaking and scattering strategy is ordinary or special, compared with the prior art, the shaking and scattering strategy can be used for shaking and scattering the clothes inside the washing machine according to the actual condition, the better shaking and scattering effect can be achieved, therefore, the problem that the existing washing machine is fixed after dehydration and is often executed, the preset shaking and scattering program is good is solved, and the technical problem that the shaking and scattering effect is poor cannot be carried out properly according to the actual condition is caused.
Optionally, when the barrel attaching condition is serious, the washing machine may be controlled to execute a special shaking and scattering strategy for N periods, wherein in each period of the N periods, the special shaking and scattering strategy is executed through the following steps:
and step S151, controlling the brake motor to rotate positively at the maximum acceleration for a third time period and then to stop suddenly.
And step S153, controlling the brake motor to reversely rotate for a fourth time length at the maximum acceleration and then suddenly stop.
Specifically, in the present embodiment, the brake motor maximum acceleration amax is rotated forward for a time t3 (i.e., the third time period), then the motor brake is used to perform an emergency stop, then the brake motor maximum acceleration amax is rotated backward for a time t4 (i.e., the fourth time period), and then the brake motor is used to perform an emergency stop, where it is noted that t3 is t4, which is one cycle, preferably, N may be 10, the third time period t3 may be 5s, and the fourth time period t3 may be 5s, that is, the present embodiment may control the brake motor to operate for 10 cycles. It should be noted that, the technical point of this scheme lies in that the effect of better trembling is reached in the back reversal of scram after controlling the corotation of brake motor, and the length of time is specific for the above-mentioned third time length and fourth time length, and this application does not make specific limitations.
Optionally, after controlling the washing machine to execute the special shaking strategy for N cycles, the method further includes:
in step S154, a front pressure value and a rear pressure value in the tub of the washing machine are acquired.
And step S155, adjusting the difference value between the third time length and the fourth time length in the special shaking and scattering strategy according to the difference value between the front pressure value and the rear pressure value in the washing machine barrel, and generating a new special shaking and scattering strategy.
And step S156, controlling the washing machine to execute a new special shaking-out strategy for M cycles.
Specifically, in this embodiment, M is preferably 5. After the control can obtain the front pressure value P and the rear pressure value P in the tub of the washing machine through two pressure sensors arranged below the inner tub and the outer tub (the pressure sensors are arranged below the inner tub and the outer tub, and the two pressure sensors are basically consistent under a normal state), it should be noted that, in combination with fig. 2, the present scheme can adjust the difference Δ t between the third time length and the fourth time length by detecting the difference Δ P between the front pressure value P and the rear pressure value P after calculating the front pressure value P and the rear pressure value P as | P front-P rear | so as to generate a new jitter strategy, i.e., the new special jitter strategy mentioned above, and if the difference Δ P between the front pressure and the rear pressure in the tub is detected to be less than or equal to the preset value P1, i.e., when the Δ P is less than or equal to P1, the front pressure and rear pressure in the tub is approximately equal, the present scheme sets the difference between t3 and t2 as 0, i.e., Δ t 387 as 0, t3 as t4, i.e., in the new jitter strategy, the forward rotation time and the reverse rotation time of the brake motor are the same. If the detected pressure is greater than P front and greater than P back and delta P is greater than P1, the pressure applied to the front of the interior of the barrel is larger and exceeds the judgment range, the washing machine inclines forwards and clothes tend forwards, the scheme adjusts the difference value between t3 and t4 to enable t3-t4 to be less than 0, namely in a new special shaking-out strategy, the forward rotation time of the brake motor is less than the reverse rotation time. If P is less than P and delta P is more than P1 after detection, it indicates that the stress at the rear part in the barrel is larger and exceeds the judgment range, the scheme makes t3-t4 be more than 0 by adjusting the difference value of t3 and t4, namely in the new special shaking-up strategy, the actual forward rotation time of the brake motor is longer than the reverse rotation time. In this way, the clothes can be subjected to backward force for a longer time so as to keep the front and back balance. If P2 >. DELTA P > P1, adjusting the difference between t3 and t4 so that t3-t4 is t 5; if P3 >. DELTA P > P2, adjusting the difference between t3 and t4 so that t3-t4 is t 6; if Δ P is not less than P3, the difference between t3 and t4 is adjusted so that t3-t4 is t7, and it should be noted that the technical point in this embodiment is that the difference between the forward rotation time and the reverse rotation time of the braking motor is adjusted by the front pressure value P and the rear pressure value P in the washing machine tub, so as to finally achieve a better shaking and dispersing effect, and the specific values of the parameters t1 to t7 and Δ t are not specifically limited in this embodiment and can be freely set according to the actual situation.
In the above steps S154 to S156, the present solution can determine a tendency of the laundry in the tub at this time by the pressure sensors before and after the tub, and the absolute value of the pressure difference Δ P before-P after reflects the degree of the tendency. Because the curvature of the lifting rib is matched with the positive and negative rotation of the inner barrel, a forward or backward force can be generated for clothes, and the clothes in the barrel can move forwards or backwards to a certain degree. In practice, it is difficult to ensure the absolute level of the inner tub of the washing machine, which may be caused by uneven ground or inclination due to the structure of the washing machine, and in the case of consistent forward and reverse rotation amplitudes, the inclination of the laundry in one direction is caused to be more serious than the sticking of the laundry to the tub. It is necessary to adjust the forward and reverse rotation time to solve the problem. Assuming that the laundry tends to move forward by the forward rotation, after the shaking logic is completed, the laundry is operated for t3 duration by the forward rotation of the maximum acceleration amax of the motor, then the sudden stop is performed by the motor brake, and then the laundry is operated for 5 cycles by the reverse rotation of the maximum acceleration amax of the motor, t4, and then the sudden stop is performed by the motor brake.
Here, when the pressure before and after the barrel is approximately equal, i.e., Δ P ≦ P1, t3 is t 4. If the pressure applied to the front inside the barrel is larger and exceeds the judgment range, namely P front is larger than P back and delta P is larger than P1, the washing machine inclines forwards and clothes tend forwards, and the forward and reverse rotation time is adjusted to enable t3 to be smaller than t 4; if the rear part in the barrel is more stressed and exceeds the judgment range, namely P front is less than P rear and delta P is more than P1, t3 is more than t 4. In this way, the clothes can be subjected to backward force for a longer time so as to keep the front and back balance. If P2 >. DELTA P > P1, then Δ t ═ t 5; if P3 >. DELTA P > P2, then Δ t ═ t 6; if the delta P is more than or equal to P3, the value is t7, and t7 is more than t6 and more than t 5.
Optionally, after the washing machine is controlled to execute a new special shaking-off strategy for 5 cycles, the present solution may judge the tub-sticking condition of the washing machine again, if the tub still sticks, the present solution continues to judge the pressure trend according to the pressure sensors in front and back of the washing machine, and adjusts the forward and reverse rotation time and runs for 5 cycles according to the pressure trend, and then performs the tub-sticking judgment again, if the tub still sticks, continues to judge the pressure trend according to the pressure sensors in front and back of the washing machine, and then adjusts the forward and reverse running time of the brake motor until the laundry does not stick to the tub.
Optionally, when the tub-attaching condition is not serious, the washing machine is controlled to execute a normal shaking-out strategy for Q cycles, wherein in each cycle of the Q cycles, the normal shaking-out strategy is executed through the following steps:
and step S157, controlling the motor of the washing machine to rotate forwards at the maximum acceleration for a first time period and then naturally decelerating to stop.
And step S157, controlling the washing machine to reversely rotate at the maximum acceleration for a second time period and then naturally decelerate to stop.
Specifically, in the present embodiment, Q is preferably 10, and the device for determining whether to fit the tub starts determining the fitting condition of the current laundry after the end of the spin-drying process. If the barrel sticking condition is light, a common shaking and scattering program is adopted, the motor is normally rotated at the maximum acceleration amax for t1 time and then naturally decelerated to stop, then the motor is reversely rotated at the maximum acceleration amax for t2 time and then naturally decelerated to stop, and t1 is t2, and the operation is carried out for 10 periods by taking the t1 as one period. Optionally, the barrel sticking condition can be judged again after 10 periods of operation, if the barrel is still stuck, 5 periods of common shaking dispersion are added until the device judges that the barrel is not stuck, otherwise, the dehydration shaking dispersion is directly considered to be finished.
An alternative embodiment of the present solution is described below with reference to fig. 3:
after the washing machine is finally taken off, the washing machine is controlled to shake and disperse, whether the barrel attaching condition of the washing machine is serious can be judged by the scheme, (1) under the condition that the barrel attaching condition is not serious, the ordinary shaking and dispersing (namely the ordinary shaking and dispersing strategy) is started to be executed for 10 periods, then whether the washing machine is attached to the barrel is judged, the ordinary shaking and dispersing are finished under the condition that the barrel is not attached, under the condition that the barrel is attached, the ordinary shaking and dispersing of 5 periods is added, then whether the barrel is attached is judged, 5 periods of the ordinary shaking and dispersing are added again under the condition that the barrel is attached, and the ordinary shaking and dispersing are finished under the condition that the barrel is not attached. (2) When the barrel is seriously attached, new shaking and scattering (namely the special shaking and scattering strategy) is started for 10 cycles, then the forward and reverse rotation time difference delta t of the brake motor is adjusted according to the pressure difference delta P between the front and the back of the washing machine acquired by the pressure sensor, then new shaking and scattering of 5 cycles is carried out, then whether the barrel is attached or not is judged, the new shaking and scattering is finished under the condition that the barrel is not attached, the delta t is adjusted according to the delta P under the condition that the barrel is attached, then new shaking and scattering of 5 cycles is added, whether the barrel is attached or not is judged, the process is finished under the condition that the barrel is not attached, the delta t is continuously adjusted through the delta P under the condition that the barrel is attached, and then new shaking and scattering of 5 cycles is added until the barrel is not attached.
The specific way for adjusting the forward and reverse rotation time difference Δ t of the brake motor according to the pressure difference Δ P of the washing machine collected by the pressure sensor is as follows:
if the difference value delta P of the front pressure and the rear pressure in the barrel is smaller than or equal to a preset value P1 through detection, namely the difference value delta P is smaller than or equal to P1, the front pressure and the rear pressure in the barrel are approximately equal, the scheme controls delta t to be 0, namely t3 to be t4, namely in a new special shaking and scattering strategy, the forward rotation time and the reverse rotation time of the brake motor are the same. If the detected pressure is greater than P front and greater than P back and delta P is greater than P1, the pressure applied to the front of the interior of the barrel is larger and exceeds the judgment range, the washing machine inclines forwards and clothes tend forwards, the scheme adjusts the difference value between t3 and t4 to enable t3-t4 to be less than 0, namely in a new special shaking-out strategy, the forward rotation time of the brake motor is actually less than the reverse rotation time. If P is less than P and delta P is more than P1 after detection, it indicates that the stress at the rear part in the barrel is larger and exceeds the judgment range, the scheme makes t3-t4 be more than 0 by adjusting the difference value of t3 and t4, namely in the new special shaking-up strategy, the actual forward rotation time of the brake motor is longer than the reverse rotation time. In this way, the clothes can be subjected to backward force for a longer time so as to keep the front and back balance. If P2 >. DELTA P > P1, adjusting the difference between t3 and t4 so that t3-t4 is t 5; if P3 >. DELTA P > P2, adjusting the difference between t3 and t4 so that t3-t4 is t 6; if Δ P is not less than P3, the difference between t3 and t4 is adjusted so that t3-t4 is t7, and it should be noted that the technical point in this embodiment is that the difference between the forward rotation time and the reverse rotation time of the braking motor is adjusted by the front pressure value P and the rear pressure value P in the washing machine tub, so as to finally achieve a better shaking and dispersing effect, and the specific values of the parameters t1 to t7 and Δ t are not specifically limited in this embodiment and can be freely set according to the actual situation.
In conclusion, the dehydration shaking logic and the barrel sticking condition judgment method with high synchronism provided by the invention can effectively judge the barrel sticking condition of the load, adjust the shaking process according to the actual condition, and use the motor with the brake to better utilize the inertia of the load to enable the load to fall off the barrel wall, thereby improving the dehydration efficiency and the subsequent drying efficiency which is possibly carried out by a washing and drying machine.
