[0058] The present disclosure is further illustrated below by way of examples, but the present disclosure is not limited to the scope of the examples.

[0060] Example 1

[0061] In order to reduce the vibration noise of the washing machine and reduce the risk of the partitioned tub colliding with the cabinet, embodiment 1 of the present disclosure provides a dehydration control method for the washing machine. Figure 1 This is a 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. The dehydration control method for the washing machine includes the following steps:

[0062] Step 101: In response to the first partitioned tub and the second partitioned tub asynchronously executing a dehydration program, the total vibration value and the resonance rotation speed point of the first partitioned tub and the second partitioned tub are obtained.

[0063] It should be noted that the resonant speed points of the first partition barrel and the second partition barrel are the same, which depends on the mass of the first partition barrel and the second partition barrel and the stiffness of their suspension systems. Take the measurement method of the resonant speed point of the first partition barrel as an example: gradually increase the speed of the first partition barrel under a certain biased load, and use the speed of the washing machine close to the natural frequency of the suspension system as the resonant speed point. At this resonant speed, resonance will occur inside the washing machine, so that the first partition barrel is closest to the box where it is located.

[0064] The total vibration value of the first partition bucket and the second partition bucket is obtained as follows:

[0065] When the first partition barrel is first subjected to a certain eccentric load and the dehydration process is started, 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 100 rpm). The eccentric load mass of the first partition barrel can be obtained through the preset correspondence between the OOB value and the eccentric load mass. The eccentric load 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:

[0066]

[0067] in, is the radius of the first partition bucket, is the angular velocity of the first partition bucket.

[0068] Obtain the vibration response values ​​of the vibration responders at k key vibration measurement points on the cabinet where the first and second partition tubs are located and the outer box of the washing machine. The vibration response values ​​of the k key vibration measurement points can reflect the overall vibration state of the two partition tubs. The vibration response value of the kth key vibration measurement point under unit eccentric load is:

[0069]

[0070] Preferably, the kth key vibration measurement point response of the first partition barrel under any eccentric load and any speed can be obtained by actual vibration test of the first partition barrel under unit eccentric load and dehydration condition. .

[0071] 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.

[0072] When the second partition barrel performs the dehydration process after the first partition barrel under a certain eccentric load, 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:

[0073] .

[0074] in, is the radius of the second partition bucket, The angular velocity of the second partition barrel rotation.

[0075] Then the vibration response of the second partition barrel at the kth key vibration measurement point under unit eccentric load is:

[0076]

[0077] Preferably, the kth key vibration measurement point response of the second partition barrel under any eccentric load and any speed can be obtained by actual vibration test of the second partition barrel under unit eccentric load and dehydration condition.

[0078] .

[0079] Then, the total vibration value of the first partition bucket and the second partition bucket is the sum of the response values ​​of k key vibration measurement points of the first partition bucket and the second partition bucket under any partial load and any speed.

[0080] Step 102: Determine a target partition bucket based on a determination result of whether the rotation speed of the first partition bucket and the rotation speed of the second partition bucket pass through a resonance rotation speed point.

[0081] It should be noted that after the above-mentioned calculation of the off-load mass is completed, that is, before the rotation speeds of the first and second partitioned tubs pass the resonance speed point, there is a possibility that the clothes will be shaken out again. This may result in the second partitioned tub running before the first partitioned tub during the spin cycle, even if the first partitioned tub starts the spin cycle before the second partitioned tub. In order to ensure that the target partitioned tub is always the one that starts the spin cycle later, the determination of whether the rotation speeds of the first and second partitioned tubs pass the resonance speed point can more accurately determine the target partitioned tub that needs speed adjustment.

[0082] Step 103: Adjust the rotation speed of the target partition bucket based on the total vibration value to control the total vibration value to be less than or equal to the vibration value threshold.

[0083] It should be noted that the vibration value threshold can be set according to actual conditions.

[0084] In this embodiment, the probability of the drum striking the washing machine is greatest at the resonance speed point, and the vibration noise of the washing machine increases as the drum speed increases past this resonance speed point. The vibration value of the drum is a key factor affecting both the vibration noise and whether the drum strikes the washing machine. Therefore, the target drum for which the speed adjustment is required is determined based on whether the speeds of the first and second drums pass through the resonance speed point. The speed of the target drum is then adjusted based on the total vibration value, so that the total vibration value is less than or equal to the vibration value threshold. This not only reduces the vibration noise of the washing machine but also reduces the risk of the drums striking the washing machine, thereby improving the user experience.

[0085] In one embodiment, the step of determining the target partitioned bucket according to the result of determining whether the rotation speed of the first partitioned bucket and the rotation speed of the second partitioned bucket pass the resonant rotation speed point specifically includes:

[0086] S1: In response to the rotation speed of the first partition bucket passing through the resonance rotation speed point, and the rotation speed of the second partition bucket not passing through the resonance rotation speed point, the second partition bucket is determined as the target partition bucket.

[0087] S2: In response to the rotation speed of the first partition bucket not passing the resonance rotation speed point, and the rotation speed of the second partition bucket passing the resonance rotation speed point, the first partition bucket is determined as the target partition bucket.

[0088] In this embodiment, since the resonance speed points of the first partition barrel and the second partition barrel are the same, when only one partition barrel passes the resonance speed point, the partition barrel that does not pass the resonance speed point will inevitably be later than the partition barrel that passes the resonance speed point during the execution of the dehydration program. Therefore, the target partition barrel can be determined more conveniently based on whether the resonance speed point is passed, and the target partition barrel can be adjusted more quickly.

[0089] In one embodiment, the step of determining the target partitioned bucket according to the result of determining whether the rotation speed of the first partitioned bucket and the rotation speed of the second partitioned bucket pass the resonant rotation speed point specifically includes:

[0090] S1: In response to the rotation speed of the first partitioned bucket and the rotation speed of the second partitioned bucket both passing through or not passing through the resonance rotation speed point, obtaining the first rotation speed of the first partitioned bucket and the second rotation speed of the second partitioned bucket.

[0091] The method for obtaining the first rotation speed of the current first partition barrel and the second rotation speed of the second partition barrel can be directly obtained by setting a sensor, or can be obtained based on the correspondence between the time when the first partition barrel and the second partition barrel execute the dehydration program and the corresponding rotation speed. Figure 2 A dehydration curve diagram of a dehydration control method for a washing machine provided in Example 1 of the present disclosure; 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 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). The dehydration curve is obtained by fitting a large number of experimental results. Therefore, the rotation speed obtained according to the dehydration curve is accurate.

[0092] S2: Determine a target partition bucket according to the first rotation speed and the second rotation speed.

[0093] In this embodiment, since the rotation speed will change according to the time when the partitioned barrel executes the dehydration program during the execution of the dehydration program, when the rotation speed of the first partitioned barrel and the rotation speed of the second partitioned barrel both pass or do not pass the resonance speed point, the target partitioned barrel can be determined by the first rotation speed of the current first partitioned barrel and the second rotation speed of the second partitioned barrel, thereby making the determination of the target partitioned barrel more accurate.

[0094] In one embodiment, the step of determining the target partition bucket according to the first rotation speed and the second rotation speed specifically includes:

[0095] S1: In response to the first rotation speed being greater than the second rotation speed, determining the second partition bucket as the target partition bucket.

[0096] S2: In response to the first rotation speed being less than the second rotation speed, determining the first partition bucket as the target partition bucket.

[0097] In this embodiment, since the rotation speed will gradually increase according to the time change of the partition barrel executing the dehydration program during the execution of the dehydration program, the target partition barrel is determined by the size relationship between the first rotation speed of the current first partition barrel and the second rotation speed of the second partition barrel, thereby making the determination of the target partition barrel more accurate.

[0098] In one embodiment, a dehydration program includes several sub-dehydration programs; the rotation speeds of the first partitioned tub and the second partitioned tub are increased in the several sub-dehydration programs; and the step of adjusting the rotation speed of the target partitioned tub based on the total vibration value to control the total vibration value to be less than or equal to the vibration value threshold specifically includes:

[0099] S1: Before the target partition barrel executes the next sub-dehydration program, predict whether the total vibration value of the target partition barrel is greater than the vibration value threshold when executing the next sub-dehydration program based on preset influencing factors; wherein the preset influencing factors include the eccentric load mass and radius of the target partition barrel and at least one of the speed predictions of the target partition barrel in the next sub-dehydration program.

[0100] It should be noted that the total vibration value corresponding to any speed of the target partition barrel when executing the next sub-dehydration program is calculated based on the eccentric load mass and radius of the target partition barrel and any speed of the target partition barrel in the next sub-dehydration program. The specific calculation method is the same as the method for calculating the total vibration value in the above step 101, which will not be repeated here.

[0101] S2: In response to the judgment result being negative, the target partition barrel is controlled to execute the next sub-dehydration procedure.

[0102] In this embodiment, by predicting in advance whether the total vibration value of the target partitioned barrel is greater than the vibration value threshold when executing the next sub-spinning program at any speed of the target partitioned barrel, the risk of increasing the vibration noise of the washing machine and the risk of the partitioned barrel hitting the cabinet can be avoided, thereby improving the user experience.

[0103] In one embodiment, the step of adjusting the rotation speed of the target partition bucket based on the total vibration value to control the total vibration value to be less than or equal to the vibration value threshold includes:

[0104] S1: In response to the speed of the first partition tub and the speed of the second partition tub both passing through the resonance speed point, controlling the total vibration value to be less than or equal to a first vibration value threshold; wherein the first vibration value threshold represents the vibration noise of the washing machine.

[0105] S2: In response to at most one of the rotational speed of the first partition barrel and the rotational speed of the second partition barrel passing through the resonant rotational speed point, the total vibration value is controlled to be less than or equal to the second vibration value threshold; wherein the second vibration value threshold is used to represent the minimum value of the box where the distance between the first partition barrel and the second partition barrel is located.

[0106] It should be noted that the first vibration value threshold and the second vibration value threshold can be set according to actual conditions.

[0107] The first and second partition buckets have different requirements in the high-speed phase (high speed refers to a speed above 1000 rpm) and the low-speed phase (low speed refers to a speed between 400 and 600 rpm):

[0108] When the first and second partition barrels are running at high speed, the radiation efficiency of vibration sound is high. Therefore, the vibration value needs to be controlled at high speed so as not to be too large, which will cause the vibration radiation noise to be too high.

[0109] When the first partition barrel and the second partition barrel are running in the low-speed stage, the vibration amplitude is high, so the vibration value of the first partition barrel and the second partition barrel needs to be controlled in the low-speed stage so that the vibration distance of the first partition barrel and the second partition barrel from the box where they are located is less than the preset minimum value, ensuring that the first partition barrel and the second partition barrel will not collide with the box where they are located.

[0110] Specifically, the rotational speed relationship between the first partition barrel and the second partition barrel can be as follows: Figure 3 shown. Figure 3 The horizontal axis represents the rotation speed of the first partition barrel or the second partition barrel, and the unit of rotation speed is rpm (revolutions per minute) Figure 3 The horizontal axis represents the displacement of the first partition barrel or the second partition barrel, and the unit of displacement is mm (millimeter). The displacement value is the distance between the first partition barrel or the second partition barrel and its corresponding box in the initial state minus the distance between the first partition barrel or the second partition barrel and its corresponding box when the dehydration program is executed.

[0111] Therefore, preferably, the first vibration value threshold and the second vibration value threshold may be set as follows:

[0112] By setting the second vibration value threshold, the total vibration value of the first partition barrel and the second partition barrel in the high-speed stage is not higher than 10% of the larger vibration value of any partition barrel at the current speed, so as to ensure that the high-frequency vibration and high-speed dehydration noise of the first partition barrel and the second partition barrel are controlled within a certain range.

[0113] By setting the second vibration value threshold, when the first partition barrel and the second partition barrel are dehydrating at the same time, the first partition barrel and the second partition barrel will not collide with the box in which they are located.

[0114] In this embodiment, by setting the first vibration value threshold and the second vibration value threshold, not only can the high-frequency vibration and high-speed dehydration noise of the first partition barrel and the second partition barrel be controlled within a reasonable range, but also the first partition barrel and the second partition barrel will not collide with the box in which they are located when the first partition barrel and the second partition barrel are running for dehydration at the same time, thereby improving the user experience.

[0115] In one embodiment, Figure 4 This is a flow chart of another dehydration control method for a washing machine provided in Example 1 of the present disclosure, combined with Figure 4 The dehydration control method of the washing machine is further explained.

[0116] S1: If the dehydration curve program of the first partition bucket is earlier than that of the second partition bucket, determine whether the first partition bucket is in the running program. If not, the second partition bucket runs according to the dehydration curve. If so, execute S2.

[0117] The dehydration curve is Figure 3 As shown, after the calculation of the eccentric load mass, that is, before the rotation speeds of the first partition tub and the second partition tub pass the resonance rotation speed point, there is a possibility that the clothes will be shaken again. As a result, even if the first partition tub executes the dehydration program before the second partition tub, the second partition tub may still run before the first partition tub during the dehydration program.

[0118] S2: Determine whether the current first partition barrel running program passes the resonance speed point. If so, execute S3; if not, execute S4.

[0119] S3: Determine whether the current second partition barrel running program has passed the resonance speed point. If so, execute S5; if not, execute S6.

[0120] S4: Determine whether the current second partition barrel running program has passed the resonance speed point. If so, execute S7; if not, execute S8.

[0121] S5: Determine whether the second partition bucket runs before the first partition bucket. If so, execute S9; if not, execute S10.

[0122] S6: Before the second partition bucket enters the next speed platform, it is determined whether the vibration value of the two buckets excited at any point on the bucket when entering the next speed platform meets X 1i + X 2i <Bucket displacement limit value. If it is met, the second partition bucket enters the next speed platform. If it is not met, the second partition bucket will wait until the first partition bucket enters the next speed platform and then make the same judgment as above until the second partition bucket enters the next speed platform.

[0123] The speed platform includes Figure 3 The barrel displacement limit value is the minimum value obtained by subtracting the distance between the first partition barrel or the second partition barrel and its corresponding box in the initial state from the distance between the first partition barrel or the second partition barrel and its corresponding box during the dehydration process.

[0124] S7: Before the first partition bucket enters the next speed platform, it is determined whether the vibration value of any point on the bucket excited by the two buckets when entering the next speed platform meets X 1i + X 2i <Bucket displacement limit value, if it is met, the first partition bucket enters the next speed platform; if it is not met, the first partition bucket waits for the second partition bucket to enter the next speed platform and then makes the same judgment as above until the first partition bucket enters the next speed platform.

[0125] S8: Determine whether the first partition bucket runs before the second partition bucket. If so, execute S11; if not, execute S12.

[0126] S9: Before the first partition bucket enters the next speed platform, it is determined whether the vibration value of the two buckets excited at any point on the bucket when entering the next speed platform meets X 1i + X 2i <1.1max{X 1i , X 2i If satisfied, the first partition bucket enters the next speed platform; if not satisfied, the first partition bucket and the second partition bucket enter the next speed platform and the same judgment is made again until the first partition bucket enters the next speed platform.

[0127] S10: Before the second partition bucket enters the next speed platform, it is determined whether the vibration value of the two buckets excited at any point on the bucket when entering the next speed platform meets X 1i + X 2i <1.1max{X 1i , X 2i If satisfied, the second partition bucket enters the next speed platform; if not satisfied, the second partition bucket waits until the first partition bucket enters the next speed platform and then makes the same judgment as above until the second partition bucket enters the next speed platform.

[0128] S11: Before the first partition bucket enters the next speed platform, it is determined whether the vibration value of the two buckets excited at any point on the bucket when entering the next speed platform meets X 1i + X 2i < Bucket displacement limit. If satisfied, the first partition bucket enters the next speed platform. If not satisfied, the first partition bucket program waits for the second partition bucket to enter the next speed platform and then makes the same judgment as above until the first partition bucket program enters the next speed platform.

[0129] S12: Before the second partition bucket enters the next speed platform, it is determined whether the vibration value of the two buckets excited at any point on the pass meets X 1i + X 2i < Bucket displacement limit.
