Detailed Description

Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

It is to be noted that, unless otherwise specified, technical terms or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which this application belongs.

A laundry treating apparatus, a control method thereof, a device thereof, and a storage medium according to embodiments of the present application will be described below with reference to the accompanying drawings.

The embodiment of the application provides a control method of clothes treatment equipment, which judges whether a load is in a winding state or not by detecting the change condition of the rotating speed of a motor in the washing process, adjusts the washing beat when the winding of the load is determined, reduces the winding condition of the load in the washing process, improves the washing effect and avoids the condition that a washing barrel collides with the washing barrel due to the winding of the load.

Referring to fig. 1, the method specifically includes the following steps:

step 101: and acquiring a first standard rotating speed fluctuation value of the motor in the current washing program.

The execution main body of the embodiment of the application is clothes treatment equipment such as a pulsator washing machine and a pulsator washing and drying integrated machine. The user puts a load to be washed, which may be laundry or beddings or the like, into the washing tub of the laundry treating apparatus and starts washing. The clothes treatment equipment detects a starting instruction submitted by a user, starts to execute a current washing program, firstly starts to feed water, and controls a motor to run at a preset beat when the water level of the fed water is determined to reach a set water level corresponding to the current washing program. The preset beat can be 700r/min, 750r/min and the like, and the beat is rotated for 1s and stopped for 1s, or is rotated for 1.5s and stopped for 1.5s and the like. The embodiment of the application does not limit the specific value of the preset beat, and the specific value can be set according to requirements in practical application.

Because the load in the washing tub is in an unwound state when the current washing program is just started to be executed, the embodiment of the application acquires the rotating speed fluctuation value of the motor in a certain number of cycles after the motor is operated, and takes the rotating speed fluctuation value acquired at the moment as the standard value for judging the rotating speed fluctuation condition of the motor in each rinsing stage in the current washing program.

Specifically, the forward rotation speed and the reverse rotation speed of each forward rotation and each reverse rotation of the motor are acquired in real time in the process that the motor runs at a preset beat, and the forward rotation speed and the reverse rotation speed of each reverse rotation can be read through a frequency converter. And acquiring the number of forward rotation times and the number of reverse rotation times of the motor in a second preset number of periods of the motor operation. The number of forward rotation times and the number of reverse rotation times can also be read from the frequency converter, or the controller is preset with the number of forward rotation times and the number of reverse rotation times of each period, and then the product of the number of forward rotation times of each period and a second preset number is calculated to obtain the number of forward rotation times of the motor in the second preset number of periods. Similarly, the product of the number of times of reversal of each cycle and a second preset number is calculated to obtain the number of times of reversal of the motor in the second preset number of cycles.

The second predetermined number of cycles may be 20 cycles or 30 cycles, etc. In the embodiment of the application, the second preset number of cycles may also be represented by a set time length, for example, the forward rotation speed, the reverse rotation speed, the forward rotation frequency and the reverse rotation frequency of each forward rotation, each reverse rotation of the motor within the set time length of the operation of the motor are obtained, and the set time length may be 2min or 3 min. The embodiment of the present application does not limit the specific value of the second preset number of cycles or the set duration, and the setting can be performed according to the requirement in practical application.

After the forward rotation speed, the reverse rotation speed, the forward rotation times and the reverse rotation times of the motor in each forward rotation in the second preset number of periods of the motor operation are obtained in the above mode, the forward rotation speed fluctuation value of the motor is calculated according to the preset target forward rotation speed, the forward rotation times and the forward rotation speed of each forward rotation. And calculating the fluctuation value of the reverse rotation speed of the motor according to the preset target reverse rotation speed, the reverse rotation times and the reverse rotation speed of each reverse rotation. Wherein the preset target forward rotation speed and the preset target reverse rotation speed are preset in the laundry treating apparatus, and the preset target forward rotation speed and the preset target reverse rotation speed may be 700r/min, 750r/min, and the like.

In one implementation, the laundry treating apparatus calculates an average forward rotation speed of the motor based on the number of forward rotations and a forward rotation speed per one forward rotation. The sum of the forward rotation speeds of each forward rotation is calculated, the ratio of the sum to the forward rotation times in a second preset number of periods is calculated, and the ratio is the average forward rotation speed of the motor in the second preset number of periods. And then calculating the difference value between the average forward rotation speed and the preset target forward rotation speed, and determining the difference value as the forward rotation speed fluctuation value of the motor in a second preset number of periods.

In another implementation, the difference between the forward rotation speed of each forward rotation and a preset target forward rotation speed is calculated respectively. And then calculating the sum of the difference values corresponding to each positive rotation, calculating the ratio between the obtained sum and the positive rotation times, and determining the ratio as the positive rotation speed fluctuation value of the motor in a second preset number of periods.

The calculation of the reverse rotation speed fluctuation value of the motor is the same as the calculation of the forward rotation speed fluctuation value, and is not repeated here. After the forward rotation speed fluctuation value and the reverse rotation speed fluctuation value of the motor in a second preset number of periods are calculated in the above mode, the forward rotation speed fluctuation value and the reverse rotation speed fluctuation value are respectively determined as a first standard forward rotation fluctuation value and a first standard reverse rotation fluctuation value corresponding to the current washing program. The first standard rotating speed fluctuation value corresponding to the current washing program comprises a first standard forward rotation fluctuation value and a first standard reverse rotation fluctuation value.

The first standard rotation speed fluctuation value corresponding to the current washing program is a rotation speed fluctuation value of the motor when the load is in an unwound state, and belongs to normal fluctuation. And in each subsequent rinsing stage, whether the rotation speed fluctuation of the motor is abnormal is judged according to the first standard rotation speed fluctuation value, and then whether the load is in a winding state is judged.

Step 102: and acquiring a first rotation speed fluctuation value of the motor every a first preset number of periods.

After the first standard rotation speed fluctuation value is determined through the step 101, the motor is continuously controlled to operate at a preset beat, and the motor rotates to drive the impeller to rotate so as to wash the load in the washing tub. The forward rotation speed of each forward rotation and the reverse rotation speed of each reverse rotation of the motor are collected in real time in the washing process. And calculating the rotating speed fluctuation value of the motor once every a first preset number of periods. Specifically, the number of forward rotations, the number of reverse rotations, the forward rotation speed per forward rotation and the reverse rotation speed per reverse rotation of the motor in a first preset number of cycles are obtained. The forward rotation speed fluctuation value and the reverse rotation speed fluctuation value of the motor in a first preset number of cycles are respectively calculated according to the manner of calculating the forward rotation speed fluctuation value and the reverse rotation speed fluctuation value of the motor in the step 101. And taking the forward rotation speed fluctuation value and the reverse rotation speed fluctuation value of the motor in a first preset number of periods as a first rotation speed fluctuation value of the motor.

Step 103: and determining whether the load is in a winding state or not according to the first rotating speed fluctuation value and the first standard rotating speed fluctuation value.

When the load is wound up, the washing resistance is increased, and the rotating speed of the impeller and the motor is reduced. The rotational speed fluctuations of the motor can be relatively large when a load is entangled. After the first rotation speed fluctuation value of the motor is calculated through step 102, the first rotation speed fluctuation value is compared with the first standard rotation speed fluctuation value determined in step 101.

Specifically, the normal rotation speed fluctuation value in the first rotation speed fluctuation values is compared with a first standard normal rotation fluctuation value included in the first standard rotation speed fluctuation value, and the reverse rotation speed fluctuation value in the first rotation speed fluctuation values is compared with a first standard reverse rotation fluctuation value included in the first standard rotation speed fluctuation value. And if the forward rotation speed fluctuation value is larger than the first standard forward rotation fluctuation value and the reverse rotation speed fluctuation value is larger than the first standard reverse rotation fluctuation value through comparison, determining that the load is in a winding state.

In order to improve the accuracy of judging whether the load is wound or not, the misjudgment rate is reduced. The embodiment of the application can also count the accumulated times that the forward rotation speed fluctuation value is greater than the first standard forward rotation fluctuation value and the reverse rotation speed fluctuation value is greater than the first standard reverse rotation fluctuation value. Specifically, when the forward rotation speed fluctuation value is larger than a first standard forward rotation fluctuation value and the reverse rotation speed fluctuation value is larger than a first standard reverse rotation fluctuation value, the accumulated times are added by one, whether the added accumulated times reach a first preset time or not is judged, and if yes, the load is determined to be in a winding state. If not, returning to the step 102, and calculating the rotation speed fluctuation value of the motor after the interval of the first preset number of cycles.

In other embodiments of the present application, since the influence degrees of various factors affecting the rotation speed of the motor on the forward rotation and the reverse rotation of the motor during the washing process are almost the same, after the forward rotation speed fluctuation value and the reverse rotation speed fluctuation value of the motor in the second preset number of cycles are calculated in step 101, the average value of the forward rotation speed fluctuation value and the reverse rotation speed fluctuation value may also be calculated, and the average value is used as the first standard rotation speed fluctuation value corresponding to the current washing program. Accordingly, in step 102, an average value of the forward rotation speed fluctuation value and the reverse rotation speed fluctuation value of the motor in the first preset number of cycles may also be calculated, and the average value may be used as the first rotation speed fluctuation value of the motor in the first preset number of cycles. And then comparing the first rotating speed fluctuation value with a first standard rotating speed fluctuation value, and if the first rotating speed fluctuation value is greater than the first standard rotating speed fluctuation value, determining that the load is in a winding state. Or if the accumulated times that the first rotating speed fluctuation value is greater than the first standard rotating speed fluctuation value reaches a first preset time, determining that the load is in a winding state.

The first predetermined number of times may be 5, 8, 10, etc. The embodiment of the application does not realize the specific value of the first preset number, and the value can be set according to requirements in practical application.

After the load is determined to be in the winding state through any one of the above modes, the running beat of the motor is also adjusted. Specifically, the motor is controlled to operate at a first preset shake-out beat for a first preset duration. The first shaking-off beat can be 500r/min or 600r/min, etc., 0.5s rotation and 0.5s stop, or 0.8s rotation and 0.8s stop, etc. The first preset time period may be 1min or 1.5min, etc. The embodiment of the application does not limit the specific values of the first shaking-out beat and the first preset time length, and can be set according to requirements in practical application.

And after the running time of the motor in the first preset shaking and scattering beat is determined to reach the first preset time, judging whether the current rinsing stage is finished, if not, returning to the step 102 again to continue monitoring the rotating speed fluctuation condition of the motor.

In order to facilitate understanding of the whole process of determining whether the load is in a winding state during the rinsing process and adjusting the motor cycle when determining the winding, the following description is made with reference to the accompanying drawings. As shown in fig. 2, S1: and determining that the water level of the inlet water reaches the set water level of the current washing program, and controlling the motor to operate at a preset beat. S2: and calculating a first standard rotating speed fluctuation value corresponding to the current washing program. S3: and controlling the motor to normally wash, and acquiring a first rotation speed fluctuation value of the motor every a first preset number of periods. S4: and judging whether the first rotating speed fluctuation value is larger than a first standard rotating speed fluctuation value or not, if so, executing the step S5, and if not, returning to the step S3. S5: the cumulative number of times is incremented by one. S6: and judging whether the accumulated times reach a first preset time, if so, executing the step S7, and if not, returning to the step S3. S7: and determining that the load is in a winding state, and controlling the motor to operate for a first preset time length at a first preset shaking-out beat. S8: and judging whether the current rinsing stage is finished or not, if so, executing the step S9, and if not, returning to the step S3. S9: a process following the current rinsing stage in the current washing process is performed.

Whether load winding appears in each rinsing stage in the washing process is monitored through the mode, and a shaking-up program is executed when the load winding appears, so that the situation that the load winding appears in the rinsing process of the impeller type clothes treatment equipment can be reduced, the washing effect is improved, and the situation that the bucket is collided due to the winding of the load can be greatly reduced.

If the current rinsing stage is finished, the subsequent dehydration procedure is required to be executed. After the rinsing stage, the shaking-dispersing program is executed once before the dewatering program is executed, so that the load is not wound together when entering the dewatering program, and the problem that the barrel is collided when dewatering is caused by winding of the load is avoided.

Specifically, after the current rinsing stage is judged to be finished, the motor is controlled to run at a second preset shaking-scattering rhythm. The second predetermined shaking-out beat may be the same as or different from the first predetermined shaking-out beat. The second preset shaking-out beat can be 500r/min or 600r/min, etc., 0.5s rotation and 0.5s stop, or 0.8s stop, etc. The embodiment of the present application does not limit the specific value of the second preset jitter cycle, and the value can be set according to the requirement in practical application.

And in the process of controlling the motor to operate at the second preset shaking-scattering rhythm, acquiring a second standard rotating speed fluctuation value of the motor in a third preset number of periods. The calculation method of the second standard rotation speed fluctuation value is the same as the calculation method of the first standard rotation speed fluctuation value in step 101, and is not described herein again.

And acquiring a second rotating speed fluctuation value of the motor every fourth preset number of periods after calculating the second standard rotating speed fluctuation value. The second rotation speed fluctuation value is calculated in the same manner as the first rotation speed fluctuation value in step 102, and is not described herein again.

And determining whether the load is still in the winding state according to the second rotating speed fluctuation value and the second standard rotating speed fluctuation value. Specifically, the second rotating speed fluctuation value is compared with a second standard rotating speed fluctuation value, if the second rotating speed fluctuation value is larger than the second standard rotating speed fluctuation value, the motor is determined to be still in the winding state, the motor is continuously controlled to run at a second preset shaking and scattering rhythm until the second rotating speed fluctuation value is smaller than or equal to the second standard rotating speed fluctuation value, the load is determined to be no longer in the winding state, and a dewatering program in the current washing program is executed subsequently.

Or, in order to improve the accuracy of the judgment, the second rotating speed fluctuation value is determined to be less than or equal to the second standard rotating speed fluctuation value, and the accumulated times are increased by one. And when the accumulated times reach a second preset time, determining that the winding state is still maintained.

In order to facilitate understanding of the shaking process before dehydration, the following description is made with reference to the accompanying drawings. As shown in fig. 3, A1: and controlling the motor to operate at a second preset shaking-out beat. A2: and acquiring a second standard rotating speed fluctuation value of the motor in a third preset number of periods. A3: and acquiring a second rotating speed fluctuation value of the motor every fourth preset number of periods. A4: and judging whether the second rotating speed fluctuation value is less than or equal to the second standard rotating speed fluctuation value, if so, executing the step A5, and if not, returning to the step A3. A5: the cumulative number of times is incremented by one. A6: and D, judging whether the accumulated times reach a second preset time, if so, executing the step A7, and if not, returning to the step A3. A7: it is determined that the load is no longer in the entangled state, and the dehydration process in the current washing process is performed.

Through the above mode, the shaking-out procedure is executed before dehydration, whether the load winding occurs in the shaking-out process is monitored, the shaking-out procedure is executed when the load winding is determined to occur, the situation that the load winding occurs in the shaking-out process of the impeller type clothes treatment equipment can be reduced, the washing effect is improved, and the situation that the bucket is collided due to the fact that the load winding occurs can be greatly reduced.

And acquiring a third standard rotating speed fluctuation value of the motor in the process of executing the dehydration program. The third standard rotational speed fluctuation value is calculated in the same manner as the first standard rotational speed fluctuation value in step 101, and will not be described in detail here. And then, acquiring a third rotation speed fluctuation value of the motor every fifth preset number of periods, wherein the calculation mode of the third rotation speed fluctuation value is the same as that of the first rotation speed fluctuation value in the step 102, and the description is omitted here.

And determining whether the washing tub eccentricity occurs according to the third rotation speed fluctuation value and the third standard rotation speed fluctuation value. Specifically, the third rotating speed fluctuation value is compared with the third standard rotating speed fluctuation value, and if the third rotating speed fluctuation value is larger than the third standard rotating speed fluctuation value through comparison, the eccentric problem of the washing tub is determined to occur. The larger the difference between the third rotation speed fluctuation value and the third standard rotation speed fluctuation value, the more serious the eccentricity.

And when the eccentricity problem is determined to occur, controlling the motor to operate at a third preset shaking-out beat for a second preset time length. The third preset shaking-out beat may be the same as or different from the first preset shaking-out beat and the second preset shaking-out beat. The third preset jitter-free beat can be 500r/min or 600r/min, etc., 0.5s rotation and 0.5s stop, or 0.8s rotation and 0.8s stop, etc. The second preset time period may be 1min or 1.5min, etc. The third preset jitter beat and the second preset time length are not limited by the embodiment of the application, and can be set according to requirements in practical application.

And if the time length of the third preset shaking-dispersing beat of the motor reaches the second preset time length and the dewatering program is not finished, continuously acquiring a third rotating speed fluctuation value of the motor every fifth preset number of periods, and monitoring whether the eccentricity problem of the washing barrel occurs in the dewatering process.

Whether the eccentricity problem occurs or not is judged according to the rotating speed fluctuation condition of the motor in the dehydration process in the mode, and the shaking and scattering program is executed when the eccentricity problem occurs, so that the phenomenon that the impeller type clothes treatment equipment collides the barrel due to winding of a load in the dehydration process can be reduced.

In the embodiment of the application, whether the load is in a winding state or not is judged by detecting the change condition of the rotating speed of the motor in the washing process, the detection accuracy is high, and the cost is low. When the load winding is determined to occur, the shaking and scattering beat is executed, the winding condition of the load in the washing process is reduced, the washing effect is improved, and the condition that the washing barrel collides with the barrel due to the winding of the load is avoided.
