All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise described herein.

Example 1
The application provides a shaking and scattering method of a washing machine, wherein the washing machine comprises a brake motor, as shown in fig. 1, and the method can comprise the following steps:
step S11, obtaining the real-time eccentric value of the washing machine.
And S13, determining the barrel sticking condition of the washing machine according to the eccentric value.
And S15, controlling the washing machine to execute a common shaking strategy or a special shaking strategy according to the barrel pasting condition of the washing machine, wherein the brake motor runs positively or negatively under the special shaking strategy.
Specifically, in the scheme, a controller or a processor of the washing machine can be adopted 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 weighing device arranged in the washing machine, then a barrel pasting 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 selectively executed according to the actual barrel pasting condition of the washing machine, and it is required to be noted that under the special shaking-off strategy, the scheme can drive a brake motor of the washing machine to perform forward rotation or reverse rotation to perform shaking-off, namely in the special shaking-off strategy, the scheme can utilize the motor with a brake, and the clothes are separated from a barrel wall of the washing machine by utilizing 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 laundry with different weight levels is put into the washing machine, the laundry with different weights corresponds 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 weighing device built in the washing machine, 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 smaller, for example, the increase of the eccentric value is smaller than 10%, it is indicated that the tub sticking or eccentric condition is lighter, the scheme adopts a common shaking strategy, and if the deviation of the real-time eccentric value and the preset eccentric value is larger, for example, the increase of the eccentric value is larger than 10%, it is indicated that the tub sticking or eccentric condition is heavier, the scheme adopts a special shaking strategy.
It can be seen from the above that, this scheme is different from the just fixed execution of prior art and presets good shake-out method, this scheme can be according to the subsides bucket condition self-adaptation decision execution ordinary shake-out tactics or special shake-out tactics of washing machine bucket clothing, compare with prior art, this scheme can shake out the clothing of washing machine inside according to actual conditions, can play better shake-out effect, consequently, through this scheme, the fixed, the good program of shaking out of preseting of often executing of current washing machine after the dehydration has been solved, lead to can not suitably shake out to shake out so that shake-out effect poor technical problem to the actual conditions.
Optionally, when the barrel sticking situation is serious, the solution can control the washing machine to execute a special shaking strategy of N periods, wherein in each period of the N periods, the special shaking strategy is executed by the following steps:
and step S151, controlling the brake motor to stop suddenly after rotating forward for a third time period at the maximum acceleration.
And step 153, controlling the brake motor to stop suddenly after reversing for a fourth time period at the maximum acceleration.
Specifically, in this scheme, the maximum acceleration amax of the braking motor is used to forward the running t3 time (i.e. the third time period), then the motor is used to perform sudden stop, then the maximum acceleration amax is used to reverse the running t4 time (i.e. the fourth time period), then the motor is used to perform sudden stop, it should be noted that, t3=t4 is taken as a period, preferably, N may be 10, the third time period t3 may be 5s, and the fourth time period t3 may be 5s, i.e. the scheme may control the braking motor to run for 10 periods. It should be noted that, the technical point of this scheme lies in, thereby control brake motor scram back after forward rotation and reverse rotation reaches better effect of trembling, and the specific duration of the aforesaid third duration and fourth duration is not specifically restricted in this application.
Optionally, after controlling the washing machine to execute the special shaking policy for N cycles, the method further includes:
step S154, a front pressure value and a rear pressure value in a tub of the washing machine are obtained.
Step S155, adjusting the difference between the third time length and the fourth time length in the special shaking strategy according to the difference between the front pressure value and the rear pressure value in the washing machine barrel, and generating a new special shaking strategy.
In step S156, the washing machine is controlled to execute a new special shaking strategy for M cycles.
Specifically, in this embodiment, M is preferably 5. The control can be performed by setting two pressure sensors (the pressure sensors are placed below the space between the inner tub and the outer tub, and the stresses of the two pressure sensors are basically consistent in a normal state) to obtain a front pressure value P and a rear pressure value P in the tub of the washing machine, and it is to be noted that, with reference to fig. 2, the difference between the third duration and the fourth duration is adjusted by detecting and calculating the difference Δp= |p front-P rear|between the front pressure value P and the rear pressure value P, so as to generate a new shaking strategy, that is, the new special shaking strategy, and if the detected difference Δp between the front pressure value P and the rear pressure value P in the tub is less than or equal to a preset value P1, that is, when Δp is less than or equal to P1, it is explained that the front pressure value P in the tub is approximately equal, the difference between t3 and t4 is set to 0, that is, Δt=0, and t 3=t4, that is, in the new special shaking strategy, the time for forward and reverse rotation of the brake motor is the same. If the detected pressure is greater than P and delta P is greater than P1, the pressure received by the front part in the barrel is larger and exceeds the judging range, the washing machine is inclined forwards and clothes tend forwards, and the scheme ensures that t3-t4 is less than 0 by adjusting the difference between t3 and t4, namely the forward rotation time of the brake motor is less than the reverse rotation time in the new special shaking strategy. If P is detected before and after P and DeltaP is more than P1, the rear stress in the barrel is larger and exceeds the judging range, and the scheme ensures that t3-t4 is more than 0 by adjusting the difference value of t3 and t4, namely in a new special shaking strategy, the forward rotation of the brake motor is actually longer than the reverse rotation time. In this way, the garment can be subjected to a rearward force for a longer period of time to maintain front-to-back balance. If P2 >. Δp > P1, then the difference between t3 and t4 is adjusted such that t 3-t4=t5; if P3 >. Δp > P2, adjusting the difference between t3 and t4 such that t 3-t4=t6; if Δp is greater than or equal to P3, the difference between t3 and t4 is adjusted so that t 3-t4=t7, and it should be noted that, in this embodiment, the technical point is that the difference between the forward rotation and reverse rotation times of the brake motor is adjusted by the front pressure value P and the rear pressure value P in the tub of the washing machine, so as to finally achieve a better shaking effect, and the specific numerical schemes of the parameters t1 to t7 and Δt are not specifically limited and can be freely set according to actual situations.
In the above steps S154 to S156, the present solution may judge a tendency of the laundry in the tub at this time through the front and rear pressure sensors in the tub, and the absolute value of the Δp= |p front-P rear|pressure difference reflects the degree of tendency. Because the bending radian of the lifting rib is matched with the forward and backward rotation of the inner drum, a forward or backward force is generated on the clothes, so that the clothes in the drum can move forwards or backwards to a certain extent. In practice, it is difficult to ensure the absolute level of the tub in the washing machine, which may be caused by uneven ground or inclination due to the structure of the washing machine, and this may result in inclination of the laundry in one direction under the condition that the forward and reverse rotation amplitudes are consistent, so that the tub sticking situation is aggravated. This is a problem that the time of the forward and reverse rotation needs to be adjusted to solve. Assuming that the forward rotation tends to make the clothes forward, after the shake-out logic is completed, the maximum acceleration amax of the motor is forward moved for t3 time, then the motor brake is used for carrying out scram, then the maximum acceleration amax of the motor is reversely moved for t4, then the motor brake is used for carrying out scram, and the cycle is taken as 5 cycles.
Here, t3=t4 when Δp is equal to or less than P1, which is the pressure in the tub in the front-rear direction is approximately equal. If the pressure received by the front part in the barrel is large and exceeds the judging range, namely, P front is more than P rear and DeltaP is more than P1, the washing machine is inclined forwards and clothes tend to be forwards, and the forward and reverse rotation time is adjusted at the moment, so that t3 is less than t4; if the rear stress in the barrel is larger and exceeds the judging range, namely P front is smaller than P rear and delta P is larger than P1, t3 is larger than t4. In this way, the garment can be subjected to a rearward force for a longer period of time to maintain front-to-back balance. If P2 > Δp > P1, Δt=t5; if P3 > Δp > P2, Δt=t6; if Δp is greater than or equal to P3, then = t7, t7 > t6 > t5.
Optionally, after the washing machine is controlled to execute a new special shaking strategy of 5 cycles, the scheme can judge the barrel sticking condition of the washing machine again, if the barrel is still stuck, the scheme continues to judge the pressure trend according to the front and rear pressure sensors of the washing machine, adjusts the forward and reverse rotation time according to the pressure trend and operates for 5 cycles, then carries out barrel sticking judgment again, if the barrel is still stuck, continues to judge the pressure trend according to the front and rear pressure sensors of the washing machine, and then adjusts the forward and reverse operation time of the brake motor until the clothes are not stuck to the barrel.
Optionally, when the barrel sticking condition is not serious, controlling the washing machine to execute a common shaking strategy of Q cycles, wherein the common shaking strategy is executed in each of the Q cycles by the following steps:
in step S157, the motor of the washing machine is controlled to naturally decelerate to a stop after being rotated forward for a first period of time at a maximum acceleration.
In step S157, the washing machine is controlled to naturally decelerate to a stop after reversing for a second period of time at the maximum acceleration.
Specifically, in this embodiment, Q is preferably 10, and the device for determining whether to attach the tub starts to determine the tub attaching condition of the current laundry after the end of the dehydration process. If the barrel sticking condition is lighter, a common shaking program is adopted, the motor is naturally decelerated to stop at the time of maximum acceleration amax positive movement t1, then is reversely rotated at the time of maximum acceleration amax for operation t2, is naturally decelerated to stop at the time of maximum acceleration amax negative movement t2, and is used as a period to operate for 10 periods. Optionally, after 10 periods of running, the barrel pasting condition can be judged again, if the barrel is still pasted, 5 periods of common shaking are added until the device judges that the barrel is not pasted, otherwise, the dehydration shaking is directly considered to be ended.
An alternative embodiment of the present solution is described below in connection with fig. 3:
after finishing the final stripping of the washing machine, the scheme controls the washing machine to shake and scatter, and can judge whether the barrel pasting condition of the washing machine is serious, and (1) under the condition that the barrel pasting condition is not serious, the normal shake and scatter (namely the normal shake and scatter strategy) is started to be executed for 10 periods, then whether the washing machine is pasted to the barrel or not is judged, the normal shake and scatter is ended under the condition that the barrel is not pasted, under the condition that the barrel is pasted, the normal shake and scatter of 5 periods is added, then whether the barrel is pasted is judged, and under the condition that the barrel is pasted, the normal shake and scatter of 5 periods is added again, and under the condition that the barrel is not pasted, the normal shake and scatter is ended. (2) Under the serious condition of barrel pasting, the method starts to execute new shaking (namely the special shaking strategy) for 10 periods, then adjusts the forward and backward rotation time difference delta t of the brake motor according to the front and rear pressure difference delta P of the washing machine, which is acquired by the pressure sensor, then executes the new shaking for 5 periods, then pastes the barrel or not, and ends the new shaking under the condition of not pasting the barrel, adjusts delta t according to delta P again under the condition of pasting the barrel, then adds the new shaking for 5 periods, then judges whether to paste the barrel or not, ends the flow under the condition of not pasting the barrel, continues to adjust delta t through delta P under the condition of pasting the barrel, and then adds the new shaking for 5 periods until the barrel is not pasted.
The specific way of adjusting the forward and reverse rotation time difference Deltat of the brake motor according to the front and rear pressure difference DeltaP of the washing machine collected by the pressure sensor is as follows:
if the detected difference DeltaP of the front pressure and the back pressure in the barrel is smaller than or equal to a preset value P1, namely DeltaP is smaller than or equal to P1, the front pressure and the back pressure in the barrel are approximately equal, and the scheme controls Deltat=0, namely t3=t4, namely in a new special shaking strategy, the time of forward rotation and reverse rotation of the brake motor is the same. If the detected pressure is greater than P and delta P is greater than P1, the pressure received by the front part in the barrel is larger and exceeds the judging range, the washing machine is inclined forwards and clothes tend forwards, and the scheme ensures that t3-t4 is less than 0 by adjusting the difference between t3 and t4, namely the forward rotation of the brake motor is actually less than the reverse rotation time in the new special shaking strategy. If P is detected before and after P and DeltaP is more than P1, the rear stress in the barrel is larger and exceeds the judging range, and the scheme ensures that t3-t4 is more than 0 by adjusting the difference value of t3 and t4, namely in a new special shaking strategy, the forward rotation of the brake motor is actually longer than the reverse rotation time. In this way, the garment can be subjected to a rearward force for a longer period of time to maintain front-to-back balance. If P2 >. Δp > P1, then the difference between t3 and t4 is adjusted such that t 3-t4=t5; if P3 >. Δp > P2, adjusting the difference between t3 and t4 such that t 3-t4=t6; if Δp is greater than or equal to P3, the difference between t3 and t4 is adjusted so that t 3-t4=t7, and it should be noted that, in this embodiment, the technical point is that the difference between the forward rotation and reverse rotation times of the brake motor is adjusted by the front pressure value P and the rear pressure value P in the tub of the washing machine, so as to finally achieve a better shaking effect, and the specific numerical schemes of the parameters t1 to t7 and Δt are not specifically limited and can be freely set according to actual situations.
In summary, the dewatering and shaking logic and the method for judging the barrel sticking condition with high synchronism can effectively judge the barrel sticking condition of the load, and the shaking process is adjusted according to the actual condition, so that the load can fall off the barrel wall by utilizing the inertia of the load better by using the motor with the brake, and further, the dewatering efficiency and the subsequent drying efficiency possibly performed by a dryer are improved.
