Description

Technical Field

[0001] The embodiments of the present application relate to the field of electrical equipment, and specifically to a washing machine and a control method and device thereof. Background Art

[0002] Compared with traditional pulsator washing machines, drum washing machines have the characteristics of water saving, high cleaning ratio, less wear and tear on clothes, and their market share is increasing. However, with the popularity of drum washing machines, some pain points reported by early users have attracted the attention of relevant manufacturers. Among them, water leakage from the washing machine door is one of the pain points that users complain about.

[0003] After repeated tests and simulations, we confirmed the main cause of the water leakage, that is, when the clothes are not placed properly, some clothes get stuck in the washing machine door (called the jam phenomenon). Washing machines with door seals will cause some clothes to get stuck between the door seal and the washing machine door. During the washing process, the stuck clothes are constantly stretched and rubbed, which will cause different degrees of deformation of the rubber door seal for washing machines with door seals. As the jam phenomenon continues to recur, it will accelerate the deformation of the washing machine door or door seal, shorten the service life of the rubber door seal, and eventually lead to water leakage during the operation of the washing machine.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0045] To achieve the above-mentioned purpose, an embodiment of the present application proposes a control method for a washing machine, wherein the washing machine may include an inner drum and a motor; the motor is configured to drive the inner drum to rotate; the method may include: executing a preset shaking process, wherein the shaking process may include steps S101-S102:

[0046] S101, controlling the inner barrel to rotate unidirectionally and accelerating at a preset target speed;

[0047] S102: When it is determined that the inner barrel rotation speed is greater than or equal to the target rotation speed and the motor parameter is less than a preset motor parameter threshold, the shaking process is terminated.

[0048] In an exemplary embodiment of the present application, before controlling the inner tub to rotate unidirectionally, the shaking process may further include:

[0049] The inner tub is controlled to rotate bidirectionally at a first washing rhythm; the first washing rhythm may include a first rotation-stop ratio; the first washing rhythm may include a first rotation speed.

[0050] The embodiment of the present application proposes a method for handling the cloth sticking phenomenon of a washing machine (such as a drum washing machine). The inventor of the present application has carefully studied the cloth sticking scenarios and found that after confirming the occurrence of the cloth sticking phenomenon, a special shaking action (a set action for shaking out the clothes in the inner drum) can be performed. For example, by executing a washing rhythm in which the inner drum rotates alternately clockwise and counterclockwise, and combining it with a unidirectional speed increase scheme during a unidirectional dehydration process (i.e. controlling the unidirectional rotation of the inner drum and accelerating it with a preset target speed as the target), the degree of cloth sticking can be reduced until the cloth sticking problem is solved.

[0051] In the exemplary embodiment of the present application, since the severity of the cloth jamming situation cannot be determined, the unidirectional speed increase plan may not be successful at one time when executing the unidirectional dehydration process, that is, the target speed may not be reached at one time, so corresponding measures need to be taken. The specific implementation plan will be explained in detail below.

[0052] In an exemplary embodiment of the present application, the jittering process may include:

[0053] S11, running a plurality of pre-set washing beats; each washing beat may include: the inner drum rotating clockwise and counterclockwise alternately once;

[0054] S12, control the inner drum to rotate unidirectionally (for example, counterclockwise) to achieve unidirectional dehydration, and increase the unidirectional speed of the inner drum during unidirectional dehydration, so as to determine whether the process of detecting whether the cloth jam phenomenon still exists according to the increase result, or directly return to step S11 to perform the shaking process again. That is, when executing the branch of detecting whether the cloth jam phenomenon exists, the current shaking process ends; if the detection result shows that the cloth jam phenomenon still exists, a new shaking process starts.

[0055] In an exemplary embodiment of the present application, during each execution of the shaking process, the number of consecutive washing beats can be customized, and no specific restrictions are made here. In an exemplary embodiment of the present application, each washing beat may include but is not limited to: the inner drum can rotate clockwise and counterclockwise alternately once.

[0056] In an exemplary embodiment of the present application, in the alternating clockwise rotation and counterclockwise rotation, the speed of the clockwise rotation and the speed of the counterclockwise rotation can be the same or different, and one or more speed mutations can be performed periodically or randomly (for example, the speed can be mainly increased suddenly, that is, the clockwise speed and / or counterclockwise speed is increased to a set value within a preset time period, and the preset time period can be as small as possible to maximize the speed mutation rate) to stretch the stuck clothes.

[0057] In an exemplary embodiment of the present application, the duration of the clockwise rotation and the counterclockwise rotation of the inner drum in each washing beat may be the same or different, and the specific duration is not limited.

[0058] In an exemplary embodiment of the present application, in each washing cycle, the inner drum can also perform multiple consecutive clockwise rotations and then perform one or more counterclockwise rotations, or perform multiple consecutive counterclockwise rotations and then perform one or more clockwise rotations, wherein the number of consecutive clockwise and counterclockwise rotations should not be too many to avoid a poor shaking effect, for example, the number of consecutive clockwise and counterclockwise rotations can be maintained at 1-3 times.

[0059] In an exemplary embodiment of the present application, an interval time may be set between one or more washing cycles, that is, the washing machine stops running for a certain period of time. The length of the interval time may be defined according to the needs, and is not specifically limited here.

[0060] In an exemplary embodiment of the present application, the same washing rhythm or different washing rhythms can be executed in each shaking process. For example, the first washing rhythm can be executed in the previous one or more shaking process executions, and the second washing rhythm can be executed in the subsequent shaking process. As the number of executions of the shaking process increases, the parameters of the executed washing rhythm can be adjusted.

[0061] In an exemplary embodiment of the present application, for example, the first washing rhythm may include a first turn-stop ratio, and the second washing rhythm may include a second turn-stop ratio, wherein the second turn-stop ratio may be greater than the first turn-stop ratio.

[0062] In an exemplary embodiment of the present application, for example, the first washing cycle may include a first rotation speed, and the second washing cycle may include a second target rotation speed, wherein the second target rotation speed may be greater than the first rotation speed. In an exemplary embodiment of the present application, in a specific embodiment, the inner drum may be rotated clockwise and counterclockwise once each as a complete washing cycle, and when the shaking process is first performed, n1 (a positive integer greater than or equal to 1, such as 10-30) first washing cycles may be continuously run.

[0063] In an exemplary embodiment of the present application, the speed of counterclockwise rotation and clockwise rotation in the first washing cycle can both be selected as 45 rpm, wherein a 5s on / 3s off operation mode can be selected, that is, at a speed of 45 rpm, it runs alternately clockwise and counterclockwise for 5 seconds and stops for 3 seconds.

[0064] In an exemplary embodiment of the present application, the controlling of the inner barrel to rotate unidirectionally and accelerating with a preset target speed as a target may include:

[0065] Controlling the inner barrel to rotate unidirectionally and accelerating with a first target speed as the target;

[0066] After the acceleration process continues for a preset time, it is determined that the inner barrel rotation speed is less than the first target rotation speed, and the acceleration is continued with the first target rotation speed as the target, and the number of acceleration times is recorded.

[0067] In an exemplary embodiment of the present application, the target rotation speed may include a first target rotation speed w1.

[0068] In an exemplary embodiment of the present application, when the unidirectional speed of the inner drum is increased during the unidirectional rotation of the inner drum for unidirectional dehydration, the unidirectional speed can be increased at a preset first increasing speed to increase the unidirectional speed to a preset first target speed w1.

[0069] In an exemplary embodiment of the present application, when the shaking process is performed for the first time, the one-way speed increase target for the one-way dehydration stage can be determined as the first target speed w1, and the first target speed w1 can be customized according to the needs. In an exemplary embodiment of the present application, it can be determined whether the detection jam phenomenon still exists or return to step S11 according to the effect of increasing the one-way speed, which can specifically include:

[0070] When the unidirectional speed is successfully increased to the first target speed w1, the motor operation data about the motor can be obtained, and it is determined whether the jamming phenomenon still exists according to the motor operation data;

[0071] When the unidirectional speed is not successfully increased to the first target speed w1, you can try to increase the unidirectional speed during the dehydration process once or multiple times to increase the unidirectional speed to the first target speed w1; and determine the subsequent execution process based on the determined number of attempts (i.e. the aforementioned acceleration number) and the attempt results.

[0072] In an exemplary embodiment of the present application, at the beginning of dehydration, the unidirectional speed may be first operated for a certain period of time at a set initial speed as the unidirectional speed, and then the unidirectional speed may be increased from the initial speed to a set target speed (such as the first target speed w1), or the unidirectional speed may be increased from the moment the speed is 0. When increasing the speed, an increase speed (such as the first increase speed mentioned above) and an increase duration may be set, and within the increase duration, the unidirectional speed may be increased from the initial speed or 0 to a set target speed (such as the first target speed w1) at the set increase speed.

[0073] In an exemplary embodiment of the present application, during the speed increasing process, when the increasing time reaches the set time, it can be detected whether the current unidirectional speed is already within the allowable fluctuation range of the first target speed. If the current unidirectional speed is already within the allowable fluctuation range of the first target speed, it can be determined that the unidirectional speed has been successfully increased to the first target speed w1. If the current unidirectional speed is not within the allowable fluctuation range of the first target speed, it can be determined that the unidirectional speed has not been accurately increased to the first target speed w1.

[0074] In the exemplary embodiment of the present application, if the unidirectional speed is successfully increased to the first target speed w1, there may be two situations. The first situation may be that the jam phenomenon has been eliminated, so the unidirectional speed of the inner drum can be increased relatively easily. The second situation may be that the jam phenomenon still exists, but because the set first target speed is relatively small, the unidirectional speed can be successfully increased to the target speed relatively easily even if the jam phenomenon exists. Since the ultimate goal is to eliminate the jam phenomenon, no matter which situation is, the motor operation data about the motor can be obtained again, and whether the jam phenomenon still exists can be identified according to the motor operation data.

[0075] In an exemplary embodiment of the present application, if the unidirectional speed is not successfully increased to the first target speed w1, considering that there may still be a slight jam, only a smaller pulling force is needed to eliminate the jam phenomenon, and in order to avoid the result being affected by other factors, the unidirectional speed can be tried again, and multiple attempts can be made. However, since the unidirectional speed cannot be successfully increased to the target speed even after many attempts under severe jamming, in order to avoid the washing machine from trying indefinitely, an attempt number threshold can be set to limit the number of attempts, and the subsequent shaking process can be determined based on the size relationship between the number of attempts and the attempt number threshold, as well as the corresponding attempt result (whether the unidirectional speed increase is successful).

[0076] In an exemplary embodiment of the present application, the method of controlling the inner barrel to rotate unidirectionally and accelerating the inner barrel to a preset target speed may further include:

[0077] An acceleration times threshold is set; when the acceleration times is equal to or greater than the acceleration times threshold, acceleration with the first target speed as the target is terminated.

[0078] In an exemplary embodiment of the present application, the method of controlling the inner barrel to rotate unidirectionally and accelerating the inner barrel to a preset target speed may further include:

[0079] When it is determined that the inner barrel rotation speed is less than the first target rotation speed and the acceleration times are equal to or greater than the acceleration times threshold, the inner barrel is controlled to rotate unidirectionally and accelerate with a preset second target rotation speed w2 as the target;

[0080] The second target speed w2 is greater than the first target speed w1.

[0081] In an exemplary embodiment of the present application, according to the above content, it can be known that the subsequent execution process in the jitter process can be determined according to the above number of attempts and the attempt results, which may specifically include:

[0082] When the number of attempts (i.e., the aforementioned number of accelerations) is less than or equal to the preset number of attempts threshold (i.e., the aforementioned number of acceleration thresholds), and the unidirectional speed has been successfully increased to the first target speed w1, the motor operation data of the current motor can be obtained, and it is determined whether the jamming phenomenon still exists based on the motor operation data;

[0083] When the number of attempts is greater than or equal to the attempt number threshold, and the unidirectional speed has not been successfully increased to the first target speed w1, the acceleration with the first target speed w1 (first target speed) as the target is terminated, and the process can be returned to step S11 to execute the shaking process again.

[0084] In an exemplary embodiment of the present application, the attempt number threshold (i.e., acceleration number threshold) can be defined according to needs. The specific value of the attempt number threshold is not limited here. For example, 2-6 times can be selected, for example, 3 times can be selected.

[0085] In an exemplary embodiment of the present application, if the unidirectional speed has been successfully increased to the first target speed w1 when the number of attempts is less than or equal to 3, it can also be said that the unidirectional speed has been increased relatively easily. At this time, it can also be identified again whether the jamming phenomenon still exists.

[0086] In an exemplary embodiment of the present application, when the unidirectional speed has not been successfully increased to the first target speed w1 after more than three attempts, it indicates that there may be a serious ground jam phenomenon. Therefore, you can try to return to step S11 and perform the shaking process at least once.

[0087] In an exemplary embodiment of the present application, the control method may further include:

[0088] When the motor parameter is greater than or equal to the preset motor parameter threshold, the shaking process can be performed at a second washing rhythm different from the first washing rhythm to obtain the number of executions of the shaking process. In an exemplary embodiment of the present application, before returning to step S11, the current number of executions of the shaking process (i.e., the total number of executions) m can be increased by 1;

[0089] When it is determined according to the motor operation data that the cloth jamming phenomenon still exists, the recorded execution times m can be obtained, and the process returns to step S11; after returning to step S11, the washing parameters corresponding to the washing beat and / or the speed to which the one-way speed should be increased (such as the second target speed) can be increased by a corresponding degree according to the execution times m of the shaking process;

[0090] When it is determined based on the motor operation data that there is no cloth jamming phenomenon, it can be determined that the cloth jamming phenomenon has been eliminated, so the shaking process can be exited and the normal washing process and dehydration process can be performed.

[0091] In an exemplary embodiment of the present application, each time the shaking process is executed, the execution count m of the shaking process can be increased by 1 and the execution count can be saved. When returning to step S11, it means that the shaking process has been completed once, so the execution count m can be increased by 1.

[0092] In an exemplary embodiment of the present application, after returning to step S11 again, the washing parameters corresponding to the washing rhythm in the shaking process and / or the target speed to which the one-way speed should be increased can be updated according to the number of times the shaking process has been executed (i.e., the number of executions) m. In an exemplary embodiment of the present application, the greater the number of executions m, the higher the degree of improvement corresponding to the washing parameters can be; correspondingly, the smaller the number of executions m, the lower the degree of improvement corresponding to the washing parameters can be.

[0093] In an exemplary embodiment of the present application, for example, after returning to step S11 again, the second washing cycle can be performed at this time.

[0094] In an exemplary embodiment of the present application, the control method may further include:

[0095] Set the execution count threshold of the jitter process;

[0096] The number of executions of the jittering process is less than or equal to the execution number threshold.

[0097] In an exemplary embodiment of the present application, the washing parameters may include: the number of operations of the washing beat and / or the inner drum rotation speed; increasing the washing parameters corresponding to the washing beat by a corresponding degree according to the size of the execution number m may include:

[0098] When m is less than a preset execution number threshold, the operation number can be increased from the first number n1 to the second number n2, and the inner drum rotation speed can be increased from the first inner drum rotation speed s1 to the second inner drum rotation speed s2;

[0099] When m is greater than or equal to a preset execution number threshold, the number of operations is increased from the first number n1 to the third number n3, and the inner drum rotation speed is increased from the first inner drum rotation speed s1 to the third inner drum rotation speed s3; wherein the third number n3 is greater than the second number n2, and the third inner drum rotation speed s3 is greater than the first inner drum rotation speed s1.

[0100] In an exemplary embodiment of the present application, according to the above scheme, the number and intensity of the washing beats (such as the inner drum rotation speed) are continuously enhanced according to the increase in the number of executions m, thereby enhancing the shaking effect.

[0101] In the exemplary embodiment of the present application, the number and intensity of the washing beats can also be continuously enhanced according to the increase in the number of attempts mentioned above. The specific implementation scheme can be the same as the scheme of continuously enhancing the number and intensity of the washing beats according to the increase in the number of executions m.

[0102] In an exemplary embodiment of the present application, the greater the number of executions m, the higher the degree of increase corresponding to the target speed to which the one-way speed should be increased; the smaller the number of executions m, the lower the degree of increase corresponding to the target speed to which the one-way speed should be increased.

[0103] In an exemplary embodiment of the present application, increasing the target speed to which the one-way speed should be increased by a corresponding degree according to the number of executions m may include:

[0104] When m is less than a preset execution number threshold, the target speed to which the unidirectional speed should be increased can be increased from the first target speed w1 to the second target speed w2;

[0105] When m is greater than or equal to a preset execution number threshold, the target speed to which the unidirectional speed should be increased can be increased from the first target speed w1 to the third target speed w3; wherein the third target speed w3 can be greater than the second target speed w2.

[0106] In the exemplary embodiment of the present application, according to the above-mentioned scheme, it is achieved that the target rotation speed is continuously increased according to the increase of the execution number m, thereby improving the pulling effect on the stuck foreign object.

[0107] In an exemplary embodiment of the present application, the target speed can also be continuously increased according to the increase in the number of attempts mentioned above. The specific implementation scheme can be the same as the scheme of continuously increasing the target speed according to the number of executions m.

[0108] In an exemplary embodiment of the present application, the jittering process may further include:

[0109] When it is determined that the rotation speed of the inner barrel is less than the preset rotation speed and the number of executions of the shaking process is greater than or equal to the execution number threshold, the shaking process is terminated.

[0110] In an exemplary embodiment of the present application, the method may further include:

[0111] When it is determined based on the motor operation data that the cloth jamming phenomenon still exists, the process can return to step S11; after returning to step S11, the washing parameters corresponding to the washing rhythm and / or the target speed to which the one-way speed should be increased can be increased to a corresponding degree based on the numerical value of the motor operation data (or motor parameters).

[0112] In an exemplary embodiment of the present application, the larger the value of the motor operation data, the higher the degree of increase in the washing parameters corresponding to the washing rhythm and / or the target speed to which the unidirectional speed should be increased; the smaller the value of the motor operation data, the lower the degree of increase in the washing parameters corresponding to the washing rhythm and / or the target speed to which the unidirectional speed should be increased.

[0113] In an exemplary embodiment of the present application, according to the above scheme, the number and intensity of washing beats (such as the drum rotation speed) are increased accordingly according to the numerical value of the motor operation data, thereby achieving a shaking effect with low energy consumption, high efficiency and more reasonable.

[0114] In an exemplary embodiment of the present application, the motor parameter (or motor operation data) may include motor torque (i.e., motor torque data), and the motor parameter threshold may include motor torque threshold; or, the motor parameter may include motor torque fluctuation, and the motor parameter threshold may include motor torque fluctuation threshold. Wherein, motor torque fluctuation may include: torque fluctuation coefficient; motor torque fluctuation threshold may include: torque fluctuation coefficient protection threshold.

[0115] In an exemplary embodiment of the present application, the motor operation data may further include: motor speed data;

[0116] The motor speed data may include: a speed fluctuation coefficient.

[0117] In an exemplary embodiment of the present application, obtaining motor operation data of a motor may include:

[0118] Detect and record the motor torque in real time in each detection cycle; determine the maximum torque value Tmax and the minimum torque value Tmin in the current detection cycle according to the recorded motor torque; calculate the torque fluctuation coefficient according to the maximum torque value Tmax, the minimum torque value Tmin and a preset torque coefficient calculation formula; and / or,

[0119] The motor speed is detected and recorded in real time in each detection cycle; the maximum speed Smax and the minimum speed Smin in the current detection cycle are determined based on the recorded motor speed; the speed fluctuation coefficient is calculated based on the maximum speed Smax, the minimum speed torque Smin and a preset speed coefficient calculation formula.

[0120] In an exemplary embodiment of the present application, judging whether the jam phenomenon still exists according to the motor operation data may include:

[0121] When the motor operation data is greater than or equal to the preset protection threshold, it can be determined that the washing machine has a jamming phenomenon;

[0122] When the motor operation data is less than the protection threshold, it can be determined that the washing machine does not have a jamming phenomenon.

[0123] In an exemplary embodiment of the present application, a scheme for identifying the jam phenomenon through motor operation data is described in detail below.

[0124] In an exemplary embodiment of the present application, a method for identifying a cloth jam of a washing machine may include:

[0125] After the washing process is started, the motor operation data of the washing machine is obtained; wherein the motor of the washing machine can be configured to drive the inner drum of the washing machine to rotate;

[0126] Comparing the motor operation data with a preset protection threshold;

[0127] Whether the washing machine has a cloth jam phenomenon is determined according to the magnitude relationship between the motor operation data and the protection threshold.

[0128] In an exemplary embodiment of the present application, a method for identifying a stuck phenomenon in a washing machine (such as a drum washing machine) is proposed. Through careful study of the stuck scenario, it is found that the motor operation data in this scenario has a predetermined change pattern. Therefore, it is possible to judge whether a stuck phenomenon exists by the change in the motor operation data.

[0134] In the exemplary embodiment of the present application, when the jamming phenomenon occurs, the motor current will also change regularly.

[0138] In the exemplary embodiment of the present application, there will generally be a small fluctuation in the motor torque during the normal washing process of the washing machine, but the fluctuation of the motor torque will be within the allowable range. If there is a jamming phenomenon, the motor torque will fluctuate greatly and exceed the allowable range. Therefore, in order to detect whether there is a jamming phenomenon, a preset torque fluctuation coefficient protection threshold can be used to detect whether the motor torque fluctuation exceeds the allowable range.

If there is a jamming phenomenon at this time, the motor speed will fluctuate greatly, thereby exceeding the preset allowable range. Therefore, in order to accurately detect whether there is a jamming phenomenon, the preset speed fluctuation coefficient protection threshold can be used to detect whether the motor speed fluctuation exceeds the preset allowable range, and the motor speed fluctuation can be represented by the speed fluctuation coefficient.
