[0053] The present disclosure is further illustrated below by way of examples, but the present disclosure is not limited to the scope of the examples.

In the embodiments of the present disclosure, the use of prefixes such as ordinal numbers to distinguish description objects does not constitute a restriction on the described objects.

[0055] Example 1

[0056] In order to reduce the vibration noise of the washing machine when two partitioned tubs in the washing machine are dehydrating at the same time, embodiment 1 of the present disclosure provides a dehydration control method for the washing machine. Figure 1 This is a first flow chart of a dehydration control method for a washing machine provided in Example 1 of the present disclosure; the washing machine includes a first partitioned tub and a second partitioned tub, and the dehydration control method for the washing machine includes the following steps:

[0057] Step 101: In response to both the first partitioned bucket and the second partitioned bucket being dehydrated, and the dehydration process of the first partitioned bucket being executed after the dehydration process of the second partitioned bucket, a first noise frequency of the first partitioned bucket and a second noise frequency of the second partitioned bucket are obtained.

[0058] When the first noise frequency of the first partition bucket and / or the second noise frequency of the second partition bucket are within the human ear sensitivity range of 4 Hz (Hertz) to 8 Hz (Hertz), noise will be generated.

[0059] The first noise frequency is:

[0060] ;

[0061] in, Characterizes the rotational angular velocity of the first partition barrel. This value is positively correlated with the rotational speed of the first partition barrel.

[0062] The second noise frequency is:

[0063] ;

[0064] in, Characterizes the rotational angular velocity of the second partition barrel. This value is positively correlated with the rotational speed of the second partition barrel.

[0065] The first noise frequency can reflect the actual noise of the first partitioned tub, and the second noise frequency can reflect the actual noise of the second washing tub, and the actual noise is beat frequency noise.

[0066] Step 102: Adjust the rotation speed of the first partitioned tub according to the first noise frequency and the second noise frequency to control the actual noise of the washing machine to be less than or equal to the noise threshold.

[0067] The noise threshold can be set according to actual conditions.

[0068] After weighing, the clothes in the partitioned tubs may need to be shaken out again. This may result in the second partitioned tub running before the first partitioned tub in the dehydration process, even if the first partitioned tub starts the dehydration process before the second partitioned tub. Therefore, the first partitioned tub is the last partitioned tub to run, and the second partitioned tub that runs first only needs to run according to the dehydration process. The dehydration speed curve of the dehydration process is as follows: Figure 2 shown. Figure 2 The horizontal axis in represents the time for the first partition barrel or the second partition barrel to execute the dehydration program, and the unit of the rotation speed is min (minute). Figure 2 The vertical axis in represents the rotation speed of the first partition barrel or the second partition barrel, and the unit of the rotation speed is rpm (revolutions per minute).

[0069] In addition, if the speed of the first partition barrel is below 100~150rpm (revolutions / minute), the noise at this stage is small and there is no need to control the speed of the first partition barrel. Figure 2 Just run the dehydration curve in .

[0070] In this embodiment, since the magnitude of the first noise frequency of the first partitioned barrel and the second noise frequency of the second partitioned barrel can reflect the noise of the washing machine, the rotation speed of the first partitioned barrel is adjusted according to the first noise frequency of the first partitioned barrel and the second noise frequency of the second partitioned barrel to change the phase difference between the two partitioned barrels. This can reduce the superposition effect of the two partitioned barrels on the sound response of the entire machine, thereby greatly reducing the vibration noise of the washing machine, thereby improving the user experience.

[0071] In one embodiment, the dehydration program includes several sub-spinning programs; the rotation speeds of the first partitioned tub and the second partitioned tub are increased in the several sub-spinning programs.

[0072] like Figure 2 As shown, each sub-dehydration program includes an acceleration phase and a constant speed phase after the acceleration phase.

[0073] The step of adjusting the rotation speed of the first partitioned tub according to the first noise frequency and the second noise frequency to control the actual noise of the washing machine to be less than or equal to the noise threshold comprises:

[0074] S1: Before the first partitioned barrel executes the next sub-dehydration program, predict the noise frequency difference between the first noise frequency and the second noise frequency when the first partitioned barrel executes the next sub-dehydration program according to the first preset influencing factor.

[0075] S2: adjusting the rotation speed of the first partition tub according to the noise frequency prediction difference to control the actual noise of the washing machine to be less than or equal to the noise threshold.

[0076] In this embodiment, the noise frequency predicted difference between the first noise frequency and the second noise frequency of the first partitioned tub when executing the next sub-spinning program is predicted in advance by the first preset influencing factor. In this way, it can be predicted in advance whether the noise of the washing machine is less than or equal to the noise threshold when the first partitioned tub executes the next sub-spinning program, so as to avoid the phenomenon that when the first partitioned tub executes the next sub-spinning program, the actual noise of the washing machine cannot be controlled to be less than or equal to the noise threshold no matter how the rotation speed of the first washing tub is adjusted.

[0077] In one embodiment, the step of adjusting the rotation speed of the first partitioned tub according to the noise frequency prediction difference to control the actual noise of the washing machine to be less than or equal to the noise threshold includes:

[0078] S1: In response to the noise frequency prediction difference being less than a noise frequency prediction difference threshold, obtaining a first sound pressure of a first partitioned bucket and a second sound pressure of a second partitioned bucket.

[0079] The noise frequency prediction difference threshold can be set based on specific circumstances. Preferably, since the human ear's sensitivity range is between 4 Hz and 8 Hz, the noise frequency prediction difference threshold can be set to 10 Hz. Therefore, if the noise frequency prediction difference is less than the noise frequency prediction difference threshold, it indicates that the actual noise emitted by the washing machine will be detected by the human ear when the first sub-drum executes the next sub-spin cycle. However, a washing machine cannot be completely silent during operation. Therefore, it is necessary to further adjust the speed by using the first sound pressure of the first sub-drum and the second sound pressure of the second sub-drum to control the actual noise to be less than or equal to the noise threshold.

[0080] The first sound pressure of the first partition bucket is obtained as follows:

[0081] When the first partition barrel is dehydrated under a certain eccentric load, the OOB (Out of Balance) value of the first partition barrel will be calculated in the early stage of the dehydration process (the speed is less than 100rpm). The eccentric mass of the first partition barrel can be obtained through the preset correspondence between the OOB value and the eccentric mass. The eccentric mass of the first partition barrel is recorded as , then the magnitude of the eccentric load excitation of the first partition barrel at any speed is:

[0082] .

[0083] in, is the eccentric load radius of the first partition bucket, is the rotational angular velocity of the first partition bucket.

[0084] Obtain the sound pressure response values of the sound pressure responders at k sound pressure measurement points on the box where the first and second partition tubs are located and the outer box of the washing machine. The sound pressure response values at the k sound pressure measurement points can reflect the overall sound pressure of the two partition tubs. The sound pressure response value of the kth sound pressure measurement point under unit eccentric load is:

[0085] .

[0086] Preferably, the sound pressure response of the first partition barrel under unit partial load dehydration can be obtained by actual sound pressure testing. Then the response of the kth sound pressure measurement point of the first partition barrel under any partial load and any speed is:

[0087] .

[0088] The method for calculating the OOB value is known in the art and will not be described in detail here. The predetermined correspondence between the OOB value and the eccentric load mass can be obtained through a large number of experiments.

[0089] The second sound pressure of the second partition bucket is obtained as follows:

[0090] When the second partition barrel executes the dehydration process before executing the dehydration process after the first partition barrel under a certain eccentric load condition, the eccentric load of the second partition barrel is obtained by the induction measurement of the OOB value: , then the magnitude of the eccentric load excitation of the second partition barrel at any speed is:

[0091] .

[0092] in, is the eccentric load radius of the second partition bucket, The angular velocity of the second partition bucket.

[0093] Then the sound pressure response of the second partition barrel at the kth sound pressure measurement point under unit eccentric load is:

[0094] .

[0095] Preferably, the sound pressure response of the kth sound pressure measurement point of the second partition barrel under any eccentric load and any rotation speed can be obtained by vibration testing the second partition barrel under unit eccentric load and dehydration conditions.

[0096] .

[0097] S2: adjusting the rotation speed of the first partitioned tub according to the first sound pressure and the second sound pressure to control the actual noise of the washing machine to be less than or equal to the noise threshold.

[0098] Figure 3 The relationship between the rotation speeds and sound responses of the first partition tub and the second partition tub in a dehydration control method for a washing machine provided in Example 1 of the present disclosure is that the sound responses of the first partition tub and the second partition tub and their corresponding sound pressures are positively correlated. Figure 3 The coordinate system in is a complex coordinate system, the horizontal axis represents the real part of the sound response amplitude of the partition bucket; the vertical axis represents the imaginary part of the sound response of the partition bucket; Indicates the rotation speed of the first partition barrel, A1 represents the sound response of the first partition barrel; A1 represents the rotation speed of the second tub, and A2 represents the acoustic response of the second tub. A1 + A2 represents the sum of the acoustic responses of the first and second tubs. Therefore, by changing the rotation speed of the first tub, the sum of the acoustic responses of the first and second tubs can be changed, thereby reducing the actual noise of the washing machine.

[0099] In this embodiment, when the noise frequency prediction difference is greater than the noise frequency prediction difference threshold, the rotation speed of the first partition barrel can be further adjusted according to the first sound pressure of the first partition barrel and the second sound pressure of the second partition barrel. In this way, the rotation speed can be adjusted more reasonably from two dimensions to control the actual noise of the washing machine to be less than or equal to the noise threshold, thereby improving the user experience.

[0100] In one embodiment, the step of adjusting the rotation speed of the first partitioned tub according to the first sound pressure and the second sound pressure to control the actual noise of the washing machine to be less than or equal to the noise threshold includes:

[0101] S1: predicting the difference between the first sound pressure and the second sound pressure when the first partitioned tub executes the next sub-dehydration program according to the second preset influencing factor.

[0102] The predicted sound pressure difference is the absolute value of the difference between the first sound pressure and the second sound pressure.

[0103] S2: In response to the sound pressure prediction difference being greater than the sound pressure prediction difference threshold, controlling the first partitioned tub to execute the next sub-spinning procedure to control the actual noise of the washing machine to be less than or equal to the noise threshold.

[0104] The sound pressure prediction difference threshold can be set according to actual conditions. Preferably, it can be set to ninety percent of the larger value of the first sound pressure and the second sound pressure.

[0105] S3: In response to the sound pressure prediction difference being less than or equal to the sound pressure prediction difference threshold, the first partitioned tub is controlled to maintain the current speed, and S1 to S3 are executed again until the actual noise of the washing machine is less than or equal to the noise threshold when the first partitioned tub executes the next sub-spin cycle.

[0106] In this embodiment, the sound pressure difference between the first sound pressure and the second sound pressure of the first partitioned tub when executing the next sub-dehydration program is predicted in advance by the second preset influencing factor. In this way, it can be predicted in advance whether the noise of the washing machine is less than or equal to the noise threshold when the first partitioned tub executes the next sub-dehydration program, so as to avoid the phenomenon that when the first partitioned tub executes the next sub-dehydration program, the actual noise of the washing machine cannot be controlled to be less than or equal to the noise threshold no matter how the rotation speed of the first washing tub is adjusted.

[0107] In one embodiment, the first preset influencing factor includes any predicted rotational speed of the first and second partitioned tubs in the next sub-spinning process of the first partitioned tub. The second preset influencing factor includes the eccentric load mass of the first and second partitioned tubs, the eccentric load radius of the first and second partitioned tubs, and any predicted rotational speed of the first and second partitioned tubs in the next sub-spinning process of the first partitioned tub.

[0108] It should be noted that any predicted speed of the first partition bucket and the second partition bucket can be based on Figure 2 The dehydration curve diagram is obtained by fitting a large number of experimental results. Therefore, the rotation speed obtained according to the dehydration curve diagram is accurate.

[0109] In one embodiment, the dehydration control method further comprises:

[0110] S1: In response to controlling the actual noise of the washing machine to be less than or equal to the noise threshold, continuing to execute the dehydration program for a preset duration, and re-acquiring a first noise frequency of the first partition tub and a second noise frequency of the second partition tub.

[0111] It should be noted that the preset duration can be set according to actual conditions.

[0112] S2: According to the re-acquired first noise frequency of the first partitioned tub and the second noise frequency of the second partitioned tub, the rotation speed of the first partitioned tub is adjusted again to control the actual noise of the washing machine to be less than or equal to the noise threshold.

[0113] In this embodiment, when the washing machine continues to execute the dehydration program, the first noise frequency of the first partition barrel and the second noise frequency of the second partition barrel are re-acquired to adjust the rotation speed of the first partition barrel again. This can avoid the phenomenon of increased noise of the washing machine when the washing machine continues to execute the dehydration program, thereby improving the user experience.

[0114] In one embodiment, Figure 5 This is a second flow chart of a dehydration control method for a washing machine provided in Example 1 of the present disclosure; Figure 5 , the dehydration control method of the washing machine is further explained.

[0115] S1: Determine whether the second partition barrel is in the dehydration program. If so, execute S2. If not, the first partition barrel runs according to the dehydration curve.

[0116] S2: Determine whether the dehydration process of the first partition barrel is after the dehydration process of the second partition barrel. If yes, execute S3; if not, execute S4.

[0117] S3: After the first partition barrel program enters the next speed platform, it is determined whether the noise frequency prediction difference is within 10Hz. If so, S5 is executed. If not, the first partition barrel program enters the next dehydration subroutine.

[0118] S4: After the second partition barrel program enters the next speed platform, it is determined whether the noise frequency prediction difference is within 10Hz. If so, S6 is executed. If not, the second partition barrel program enters the next dehydration subroutine.

[0119] S5: After the first partition bucket enters the next speed platform, it is determined whether the sound pressure prediction difference is greater than 0.9max{P1i, P2i}. If so, the first partition bucket program enters the next dehydration subroutine. If not, the second partition bucket program enters the next dehydration subroutine and executes S3 again.

[0120] S6: After the second partition bucket enters the next speed platform, it is determined whether the sound pressure prediction difference is greater than 0.9max{P1i, P2i}. If so, the second partition bucket program enters the next dehydration subroutine. If not, the second partition bucket program enters the next dehydration subroutine and executes S4 again.
