[0001] This application belongs to the field of home appliance technology, and in particular relates to a washing control method, washing control device, storage medium and washing machine. Background Technology

[0002] A washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. It can automatically clean clothes and improve the user experience.

[0003] In related technologies, during the washing process, the increased foam leads to increased pressure inside the washing machine, and consequently, increased water pressure. A water level detection device inside the washing machine is used to monitor this water pressure, thereby detecting the amount of foam. However, currently used mechanical water level detection devices have low accuracy, often only detecting foam when it is already quite abundant. This inaccurate detection of foam content results in a poor user experience and negatively impacts washing performance. Summary of the Invention

[0061] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0062] In related technologies, during the washing process, the increased foam leads to increased pressure inside the washing machine, and consequently, increased water pressure. A water level detection device inside the washing machine is used to monitor this water pressure, thereby detecting the amount of foam. However, currently used mechanical water level detection devices have low accuracy, often only detecting foam when it is already quite abundant. This inaccurate detection of foam content results in a poor user experience and negatively impacts washing performance.

[0063] To address the aforementioned problems, embodiments of this application provide a control method for a washing machine, a control device for a washing machine, a storage medium, and a washing machine. Please refer to [link to relevant documentation]. Figure 1 , Figure 1 This is a schematic flowchart of the first embodiment of the washing control method provided in this application. The washing control method is applied to a washing machine, which can be a vented washing machine, a heat pump washing machine, or a condensing washing machine, etc. The washing machine may include an inner drum and a motor. The inner drum can be used to hold the clothes to be washed, and the motor can drive the inner drum to rotate. The specific flow of the method is as follows:

[0064] 101. If the washing machine's washing program is started, obtain the initial power information of the motor.

[0065] In this embodiment, the user can control the washing machine to power on via physical or virtual buttons on the washing machine. After the washing program of the washing machine is started, the initial power information of the motor can be obtained.

[0066] In some embodiments, if the washing machine's washing program is started, water is introduced into the inner drum until the inner drum reaches the initial water level, and the motor is controlled to drive the inner drum to rotate at a fourth speed, wherein the average power of the motor during a third preset time when the inner drum rotates at the fourth speed is the initial power information.

[0067] Specifically, the inner cylinder may include lifting ribs, the height of which can be 30-50mm. The initial water level W1 of the inner cylinder can be half or close to the height of the lifting ribs. For example, if the height of the lifting ribs is 30mm, the initial water level is 15-30mm; or if the height of the lifting ribs is 50mm, the initial water level can be 25-50mm. Then, the inner cylinder is controlled to rotate at a fourth rotation speed, which can be 25-40 revolutions per minute.

[0068] Optionally, the motor can drive the inner drum to rotate. When the inner drum rotates at the fourth speed, the average power of the motor over a third preset time period can be the initial power information p. It should be noted that after the washing program starts, the motor power gradually increases from zero to the target power that can drive the inner drum to rotate at the fourth speed. Therefore, the third preset time can be a period of time after the inner drum reaches the fourth speed, such as 30-60 seconds. The initial power information p is the average power of the motor during the 30-60 seconds when the inner drum rotates stably at the fourth speed, where there is a target power per second.

[0069] 102. When the motor drives the inner cylinder to rotate at the first speed, the first power information of the motor and the first time information of the inner cylinder rotation are obtained.

[0070] When the motor drives the inner cylinder to switch from the fourth speed to the first speed, the first power information of the motor and the first time information of the inner cylinder rotation are obtained.

[0071] In some embodiments, when the motor drives the inner cylinder to rotate at a first speed, the number of rotations of the inner cylinder within a first preset time period is obtained, wherein each rotation of the inner cylinder corresponds to a first time value and a first power value of the motor; based on the number of rotations, multiple first time values ​​and multiple first power values ​​corresponding to the inner cylinder within the first preset time period are obtained.

[0072] The first preset time is the period during which the inner cylinder switches from the fourth speed to the first speed and maintains a stable rotation at the first speed, such as 30-60 seconds. After obtaining the number of rotations of the inner cylinder within the first preset time, each rotation of the inner cylinder corresponds to a first time value T1 and a first power value P1 of the motor. For example, if the first time value T1 and the first power value P1 are recorded once for each rotation of the inner cylinder, then multiple first time values ​​T1 and multiple first power values ​​P1 can be recorded within the first preset time, such as (P11, T11), (P12, T12)...(P1n, T1n), etc. To improve the detection accuracy, at least 20 first time values ​​T1 and first power values ​​P1 can be obtained as sample data.

[0073] In some embodiments, when the motor drives the inner cylinder to rotate at a first speed, at least two target time periods within the target time of one rotation of the inner cylinder are obtained, and at least two second power values ​​of the motor corresponding to the at least two target time periods are obtained.

[0074] In this process, after the inner cylinder rotates stably at a first speed, the target time for each rotation is obtained. The target time can be 25-30 seconds. The target time includes at least two target time periods T2, which can be the first 2-3 seconds and the last 2-3 seconds of the inner cylinder's rotation. For example, if the target time for the inner cylinder's rotation is 22 seconds, then the first target time period can be 0-2 seconds, and the second target time period can be 20-22 seconds. The motor power value can be recorded once every second the inner cylinder rotates. The average power value of the first target time period and the average power value of the second target time period can both be used as a second power value P2. Therefore, at least two target time periods correspond to at least two second power values ​​P2.

[0075] 103. Fit the initial power information, the first power information, and the first time information to obtain the first fitting formula, wherein the first fitting formula includes the first fitting parameters.

[0076] In some embodiments, after obtaining multiple first time values ​​and multiple first power values, a first fitting formula is obtained by fitting the initial power information obtained by rotating at a fourth rotation speed, the multiple first time values, and the multiple first power values, wherein the first fitting formula includes first fitting parameters.

[0077] Specifically, multiple first time values ​​T1 and multiple first power values ​​P1 are used as discrete data, and combined with the initial power information p, linear fitting is performed using the least squares method to obtain the linear fitting formula P1 = K1 * T1 + p for the first power value P1 and the first time value T1, where K1 is the first fitting parameter.

[0078] In some embodiments, after obtaining at least two target time periods and at least two second power values, a first fitting formula is obtained by fitting the initial power information obtained by rotating at a fourth rotation speed, the at least two target time periods, and the at least two second power values, wherein the first fitting formula includes first fitting parameters.

[0079] Specifically, the two target time periods T2 and the two second power values ​​P2 are used as two sample data, and the initial power information p is combined with the two-point method to perform linear fitting, so as to obtain the fitting formula of the second power value P2 and the target time period T2: P2 = K1*T2 + p, where K1 is the first fitting parameter.

[0080] 104. Based on the first fitting parameters, determine the foam content range in the inner cylinder.

[0081] After obtaining the first fitting formula through the least squares method and / or the two-point method, the foam content in the inner cylinder can be determined by the first fitting parameter in the first fitting formula, that is, the foam content range in the inner cylinder can be determined according to the first fitting parameter.

[0082] In some embodiments, if the first fitting parameter is greater than or equal to the first preset threshold, the foam content range in the inner cylinder is the first range; if the first fitting parameter is greater than or equal to the second preset threshold and less than the first preset threshold, the foam content range in the inner cylinder is the second range; if the first fitting parameter is less than the second preset threshold, the foam content in the inner cylinder is the third range, wherein the foam content in the first range is greater than the foam content in the third range.

[0083] Specifically, the formula corresponding to the first power value P1 is P1 = K1 * T1 + p, and the formula corresponding to the second power value P2 is P2 = K1 * T2 + p. Both formulas are fitting formulas for the motor's power value. Therefore, the formula corresponding to the motor's power value P can be P = K1 * T + p, where the first fitting parameter K1 is the slope of the first fitting formula. The larger K1 is, the larger the corresponding motor power value P is. It can be understood that if the motor power value is larger, it indicates that there is more foam in the clothes to be washed during the washing process. Therefore, the foam content in the inner drum can be determined by the first fitting parameter K1. Specifically, if the first preset threshold a1 is greater than the second preset threshold a2, and the first fitting parameter K1 is greater than or equal to the first preset threshold a1, it indicates that the motor power is high, the foam content is in the first interval (higher foam content), and if the washing process is followed normally, there is a risk of foam overflowing from the inner drum. Conversely, if the first fitting parameter K1 is less than the second preset threshold a2, it indicates that the motor power is low, the foam content is in the third interval (lower foam content), and the washing process can be followed normally. Furthermore, if the first fitting parameter K1 is less than the second preset threshold a2, it indicates that the motor power is normal. In this case, the foam content in the inner drum cannot be accurately determined solely by the motor power value P and the first fitting parameter K1. Therefore, when the foam content is in the third interval, the foam content is in a state of pending confirmation.

[0084] 105. Based on the foam content range, control the washing program to execute the washing process corresponding to the foam content range in order to wash the clothes to be washed.

[0085] In some embodiments, if the foam content range in the inner drum is a first range, the washing program is controlled to enter a defoaming washing process, wherein the motor drives the inner drum to rotate at a second speed, which is less than the first speed, during the defoaming washing process; the first current foam content is obtained, and it is determined whether the first current foam content meets the end condition of the defoaming washing process; if it does, the washing of the clothes to be washed is completed; if it does not, the defoaming washing process continues until the end condition of the defoaming washing process is met.

[0086] Specifically, if the foam content in the inner drum falls within the first range, it indicates a high foam content. Therefore, the washing program needs to enter a defoaming cycle, in which the motor drives the inner drum to rotate at a second speed. It's understandable that to improve the efficiency of foam removal in the inner drum, the washing program's efficiency can be increased by reducing the inner drum's rotation speed, increasing the total washing time at the second speed, or increasing the time per revolution of the inner drum. Alternatively, the washing efficiency can be improved by altering the heating element's heating cycle.

[0087] It should be noted that during the process of determining the foam content range in the inner drum using the first fitted parameters, the inner drum operates at the first rotation speed. After obtaining the first fitted parameters, the inner drum switches from the first rotation speed to the fourth rotation speed. Since the second rotation speed is lower than the first rotation speed, and the inner drum has already slowed down to the fourth rotation speed, if the washing program enters the defoaming control program, the rotation speed of the inner drum needs to be further reduced, thus reducing the rotation speed of the inner drum from the fourth rotation speed to the second rotation speed. Therefore, the fourth rotation speed is lower than the first rotation speed, and the fourth rotation speed is higher than the second rotation speed. The second rotation speed can be 20-30 revolutions per minute.

[0088] If, after the inner drum rotates at the second speed for a certain period of time during the defoaming control process, the first current foam content in the inner drum is detected to be lower than the preset foam content threshold, it indicates that the first current content meets the defoaming washing process. At this time, the foam content in the inner drum is low or close to zero, so the washing program can be ended and the washing of the clothes to be washed can be completed. If the first current content does not meet the defoaming washing process, it indicates that the foam content in the inner drum is still high, and the washing process needs to continue until the first current content is lower than the preset foam content threshold.

[0089] In some embodiments, if the foam content in the inner drum is in the third range, the washing program is controlled to enter the normal washing program, wherein the motor drives the inner drum to rotate at a third speed, wherein the third speed is greater than the first speed; the second current foam content is obtained, and it is determined whether the second current foam content meets the end condition of the normal washing program; if yes, the washing of the clothes to be washed is completed; if no, the normal washing process continues until the end condition of the normal washing process is met.

[0090] Specifically, if the foam content in the inner drum is in the third range, it indicates that there is little or no foam in the inner drum, and the washing program can enter the normal washing program. In the normal washing program, the motor drives the inner drum to switch from the first speed to the third speed. The third speed is greater than the first speed, and the third speed can be 40-55 rpm. Since the third speed is greater than the first speed, when the first speed is 35 rpm, the third speed can be 40 rpm; when the first speed is 45 rpm, the third speed can be 55 rpm. The inner drum can rotate in the third periodic switching mode at the third speed. The switching sequence of the third periodic switching mode can be clockwise rotation for 10-15 seconds, stop rotation for 1-5 seconds, counterclockwise rotation for 10-15 seconds, stop rotation for 1-5 seconds, and maintain the logic of alternating clockwise and counterclockwise periodic switching. The third periodic switching mode has a shorter rotation time and a shorter stop time compared to the second periodic switching mode.

[0091] If, after the inner drum rotates at the third speed for a certain period of time during the normal control process, the second current content of foam in the inner drum is detected to be lower than the preset foam content threshold, it means that the second current content meets the normal washing process. At this time, the foam content in the inner drum is low or close to zero, so the washing program can be ended and the washing of the clothes to be washed can be completed. If the second current content does not meet the normal washing process, it means that the foam in the inner drum still needs to be further eliminated until the first current content is lower than the preset foam content threshold, so as to improve the washing effect.

[0092] Of course, when the inner drum rotates at the third speed, the target washing time for that rotation can be obtained. If the target washing time is longer than the preset target washing time, the washing program is completed; if the target washing time is shorter than the preset target washing time, the inner drum continues to rotate at the third speed to wash the clothes. The target washing time is the washing time from the start of the inner drum rotating at the third speed to the current washing time, and the target washing time can be 10-20 minutes.

[0093] In some embodiments, if the foam content in the inner drum is within a second range, it indicates that the foam content in the inner drum is in a stage to be determined. At this time, it is necessary to obtain the initial water level of the inner drum, multiple second time values ​​of the inner drum rotating within a second preset time, and multiple first water levels corresponding to the multiple second time values, wherein one second time value corresponds to one first water level. The initial water level, multiple second time values, and multiple first water levels are fitted to obtain a second fitting formula, wherein the second fitting formula includes at least a second fitting parameter. If the second fitting parameter is less than or equal to a third preset threshold, the washing program is controlled to enter the defoaming washing process. If the second fitting parameter is greater than the third preset threshold, the washing program is controlled to enter the normal washing process.

[0094] Specifically, the initial water level W1 of the inner cylinder is obtained. The initial water level W1 is half or close to the height of the lifting ribs. For example, if the height of the lifting ribs is 30mm, the initial water level is 15-30mm; or if the height of the lifting ribs is 50mm, the initial water level can be 25-50mm. At this time, the inner cylinder rotates at the fourth speed. After the inner cylinder switches from the fourth speed to the first speed and maintains a stable speed, multiple second time values ​​T2 of the inner cylinder rotation within a second preset time period and multiple first water levels W2 corresponding to the multiple second time values ​​T2 are obtained. The first water level W2 can be close to the height of the lifting ribs or higher than the height of the lifting ribs. For example, if the height of the lifting ribs is 30mm, the first water level can be 30-35mm; or if the height of the lifting ribs is 50mm, the first water level can be 50-55mm. In this process, a second time value T2 and a first water level W2 are collected every second, such as (W21, T21), (W22, T22)...(W2n, T2n), etc. To improve detection accuracy, at least 10 second time values ​​T2 and first water level W2 can be acquired every second as sample data.

[0095] Multiple second time values ​​T2 and multiple first water level values ​​W2 are used as discrete data. Combined with the initial water level W1, a linear fit is performed using the least squares method to obtain the linear fitting formula W2 = K2 * T2 + W1 for the first water level W2 and the second time value T2. Here, K2 is the second fitting parameter and the slope of the second fitting formula. Since the water in the inner drum is absorbed by the clothes during the washing process, the first water level W2 gradually decreases; therefore, the second fitting parameter K2 is negative. It can be understood that if the first water level W2 decreases rapidly during the washing process, i.e., the second fitting parameter K2 is smaller and the slope is steeper, it indicates that the clothes have more foam and require more water for washing. Therefore, the foam content in the inner drum can be further determined using the second fitting parameter K2.

[0096] If the second fitting parameter K2 is less than or equal to the third preset threshold, it indicates that there is a lot of foam in the inner drum, and the washing program needs to be controlled to enter the defoaming washing process; if the second fitting parameter is greater than the third preset threshold, it indicates that there is little or no foam in the inner drum, and the washing program needs to be controlled to enter the normal washing process.

[0097] As can be seen from the above, in this embodiment, if the washing machine's washing program is started, the initial power information of the motor is obtained; when the motor drives the inner drum to rotate at a first speed, the first power information of the motor and the first time information of the inner drum rotation are obtained; the initial power information, the first power information, and the first time information are fitted to obtain a first fitting formula, wherein the first fitting formula includes first fitting parameters; based on the first fitting parameters, the foam content range in the inner drum is determined; based on the foam content range, the washing program is controlled to execute the washing process corresponding to the foam content range to wash the clothes to be washed. This embodiment improves the accuracy of foam detection by judging the fitting parameters in the fitting formula, thereby improving the washing effect.

[0098] Please see Figure 2 , Figure 2 This is a second flowchart illustrating the laundry control method provided in this application. The specific operation steps of this laundry control method are as follows:

[0099] 201. If the washing machine's washing program is started, the motor is controlled to drive the inner drum to rotate at the fourth speed, and the initial power information of the motor is obtained.

[0100] In this embodiment, the user can control the washing machine to power on via physical or virtual buttons on the washing machine. After the washing program of the washing machine is started, the initial power information of the motor can be obtained.

[0101] In some embodiments, if the washing machine's washing program is started, water is introduced into the inner drum until the inner drum reaches the initial water level, and the motor is controlled to drive the inner drum to rotate at a fourth speed, wherein the average power of the motor during a third preset time when the inner drum rotates at the fourth speed is the initial power information.

[0102] It should be noted that the inner drum may include lifting ribs. The function of the lifting ribs is to generate friction between the clothes and the ribs during washing, causing relative movement and friction between the contact areas to create a rubbing effect. Additionally, the lifting ribs can rotate the clothes, lifting them to the water level and reaching a certain height before they fall back into the water due to gravity, thus achieving a washing effect through the principle of tumbling. In this embodiment, the height of the lifting ribs can be 30-50mm. The water level in the inner drum is corresponding to the height of the lifting ribs. Setting the water level according to the height of the lifting ribs ensures that during washing, the lifting ribs can lift the clothes to a certain height above the water level while preventing them from contacting the inner wall of the drum. This allows the clothes to be thoroughly washed and soaked, improving the washing effect.

[0103] Specifically, the initial water level W1 of the inner cylinder can be half or close to the height of the lifting ribs. For example, if the height of the lifting ribs is 30mm, the initial water level is 15-30mm; or if the height of the lifting ribs is 50mm, the initial water level can be 25-50mm. Then, the inner cylinder is controlled to rotate at a fourth speed, which can be 25-40 revolutions per minute. The inner cylinder can rotate at the fourth speed according to the first periodic switching method. The sequence of the first periodic switching method can be clockwise rotation for 20-30 seconds, stop rotation for 10-15 seconds, counterclockwise rotation for 20-30 seconds, stop rotation for 10-15 seconds, and maintain the logic of alternating clockwise and counterclockwise periodic switching.

[0104] Optionally, the motor can drive the inner drum to rotate. When the inner drum rotates at the fourth speed, the average power of the motor over a third preset time period can be the initial power information p. It should be noted that after the washing program starts, the motor power gradually increases from zero to the target power that can drive the inner drum to rotate at the fourth speed. Therefore, the third preset time can be a period of time after the inner drum reaches the fourth speed, such as 30-60 seconds. The initial power information p is the average power of the motor during the 30-60 seconds when the inner drum rotates stably at the fourth speed, where there is a target power per second.

[0105] Understandably, as clothes absorb water during washing, the water level in the inner drum gradually decreases. When the water level drops to a preset threshold, the inner drum needs to be replenished. Therefore, a water level detection device installed in the inner drum can detect the water level in real time. Specifically, the water level detection device can detect the water level frequency value in the inner drum. The water level can be obtained from the water level frequency value. The water level frequency value and the water level are inversely proportional. That is, if the water level frequency value is higher than the preset water level frequency threshold, it means that the water level is lower than the preset water level threshold. At this time, the inner drum needs to be replenished until the water level in the inner drum reaches the initial water level W1, so as to ensure that the water level in the inner drum can support the washing of clothes.

[0106] In some embodiments, the duration of the inner drum without water replenishment after reaching the initial water level and the current washing duration of the washing program can be obtained; if the duration of the lack of water replenishment is longer than the preset duration of the lack of water replenishment, or the current washing duration is longer than the preset washing duration, the motor is controlled to drive the inner drum to switch from the fourth speed to the first speed.

[0107] It should be noted that the "no water replenishment time" refers to the duration during which no water is replenished after the inner drum initially fills with water to the initial water level W1. During this time, the water level in the inner drum remains above the preset water level threshold, thus eliminating the need for water replenishment. The water level in the inner drum during this period ensures that the clothes to be washed are fully saturated. If the no-water replenishment time exceeds the preset time, it indicates that the clothes have fully absorbed water, and the water level in the inner drum is still sufficient to support washing. In this case, the motor can be controlled to switch the inner drum's rotation speed from the fourth speed to the first speed. This no-water replenishment time can be 30-60 seconds. Furthermore, after the water replenishment operation brings the water level in the inner drum back to the initial water level W1, the continuous no-water replenishment time needs to be reset.

[0108] It should also be noted that the current washing duration can be the washing time from the start of the washing program to the current washing time. A fixed washing duration can be set for each washing stage of the program. If the current washing duration is longer than the preset washing duration, the control motor will switch the inner drum's rotation speed from the fourth speed to the first speed. The preset washing duration can be 3-5 minutes. The fourth speed is less than the first speed, and the first speed can be 35-45 rpm. When the fourth speed is 25 rpm, the first speed can be 35 rpm; when the fourth speed is 40 rpm, the first speed is 45 rpm. The inner drum rotates at the first speed using a second periodic switching method. The switching sequence for the second periodic switching method can be clockwise rotation for 15-25 seconds, stop rotation for 5-10 seconds, counterclockwise rotation for 15-20 seconds, and stop rotation for 5-10 seconds, maintaining an alternating clockwise and counterclockwise periodic switching logic. The second periodic switching method has shorter rotation and stop times compared to the first periodic switching method. Of course, the preset time without water replenishment and preset washing time can also be set according to the weight of the clothes to be washed. The specific setting method is not limited here.

[0109] 202. When the motor drives the inner cylinder to switch from the fourth speed to the first speed, the first power information of the motor and the first time information of the inner cylinder rotation are obtained.

[0110] In some embodiments, when the motor drives the inner cylinder to rotate at a first speed, the number of rotations of the inner cylinder within a first preset time period is obtained, wherein each rotation of the inner cylinder corresponds to a first time value and a first power value of the motor; based on the number of rotations, multiple first time values ​​and multiple first power values ​​corresponding to the inner cylinder within the first preset time period are obtained.

[0111] The first preset time is the period during which the inner cylinder switches from the fourth speed to the first speed and maintains a stable rotation at the first speed, such as 30-60 seconds. After obtaining the number of rotations of the inner cylinder within the first preset time, each rotation of the inner cylinder corresponds to a first time value T1 and a first power value P1 of the motor. For example, if the first time value T1 and the first power value P1 are recorded once for each rotation of the inner cylinder, then multiple first time values ​​T1 and multiple first power values ​​P1 can be recorded within the first preset time, such as (P11, T11), (P12, T12)...(P1n, T1n), etc. To improve the detection accuracy, at least 20 first time values ​​T1 and first power values ​​P1 can be obtained as sample data.

[0112] In some embodiments, when the motor drives the inner cylinder to rotate at a first speed, at least two target time periods within the target time of one rotation of the inner cylinder are obtained, and at least two second power values ​​of the motor corresponding to the at least two target time periods are obtained.

[0113] In this process, after the inner cylinder rotates stably at a first speed, the target time for each rotation is obtained. The target time can be 25-30 seconds. The target time includes at least two target time periods T2, which can be the first 2-3 seconds and the last 2-3 seconds of the inner cylinder's rotation. For example, if the target time for the inner cylinder's rotation is 22 seconds, then the first target time period can be 0-2 seconds, and the second target time period can be 20-22 seconds. The motor power value can be recorded once every second the inner cylinder rotates. The average power value of the first target time period and the average power value of the second target time period can both be used as a second power value P2. Therefore, at least two target time periods correspond to at least two second power values ​​P2.

[0114] 203. Fit the initial power information, the first power information, and the first time information to obtain the first fitting formula, wherein the first fitting formula includes the first fitting parameters.

[0115] In some embodiments, after obtaining multiple first time values ​​and multiple first power values, a first fitting formula is obtained by fitting the initial power information obtained by rotating at a fourth rotation speed, the multiple first time values, and the multiple first power values, wherein the first fitting formula includes first fitting parameters.

[0116] Specifically, multiple first time values ​​T1 and multiple first power values ​​P1 are used as discrete data, and combined with the initial power information p, linear fitting is performed using the least squares method to obtain the linear fitting formula P1 = K1 * T1 + p for the first power value P1 and the first time value T1, where K1 is the first fitting parameter.

[0117] In some embodiments, after obtaining at least two target time periods and at least two second power values, a first fitting formula is obtained by fitting the initial power information obtained by rotating at a fourth rotation speed, the at least two target time periods, and the at least two second power values, wherein the first fitting formula includes first fitting parameters.

[0118] Specifically, the two target time periods T2 and the two second power values ​​P2 are used as two sample data, and the initial power information p is combined with the two-point method to perform linear fitting, so as to obtain the fitting formula of the second power value P2 and the target time period T2: P2 = K1*T2 + p, where K1 is the first fitting parameter.

[0119] 204. Based on the first fitting parameters, determine the foam content range in the inner cylinder.

[0120] After obtaining the first fitting formula through the least squares method and / or the two-point method, the foam content in the inner cylinder can be determined by the first fitting parameter in the first fitting formula, that is, the foam content range in the inner cylinder can be determined according to the first fitting parameter.

[0121] In some embodiments, if the first fitting parameter is greater than or equal to the first preset threshold, the foam content range in the inner cylinder is the first range; if the first fitting parameter is greater than or equal to the second preset threshold and less than the first preset threshold, the foam content range in the inner cylinder is the second range; if the first fitting parameter is less than the second preset threshold, the foam content in the inner cylinder is the third range, wherein the foam content in the first range is greater than the foam content in the third range.

[0122] Specifically, the formula corresponding to the first power value P1 is P1 = K1 * T1 + p, and the formula corresponding to the second power value P2 is P2 = K1 * T2 + p. Both formulas are fitting formulas for the motor's power value. Therefore, the formula corresponding to the motor's power value P can be P = K1 * T + p, where the first fitting parameter K1 is the slope of the first fitting formula. The larger K1 is, the larger the corresponding motor power value P is. It can be understood that if the motor power value is larger, it indicates that there is more foam in the clothes to be washed during the washing process. Therefore, the foam content in the inner drum can be determined by the first fitting parameter K1. Specifically, if the first preset threshold a1 is greater than the second preset threshold a2, and the first fitting parameter K1 is greater than or equal to the first preset threshold a1, it indicates that the motor power is high, the foam content is in the first interval (higher foam content), and if the washing process is followed normally, there is a risk of foam overflowing from the inner drum. Conversely, if the first fitting parameter K1 is less than the second preset threshold a2, it indicates that the motor power is low, the foam content is in the third interval (lower foam content), and the washing process can be followed normally. Furthermore, if the first fitting parameter K1 is less than the second preset threshold a2, it indicates that the motor power is normal. In this case, the foam content in the inner drum cannot be accurately determined solely by the motor power value P and the first fitting parameter K1. Therefore, when the foam content is in the third interval, the foam content is in a state of pending confirmation.

[0123] 205. If the foam content in the inner drum is in the first range, the washing program is controlled to enter the defoaming washing process, in which the motor drives the inner drum to rotate at the second speed during the defoaming washing process.

[0124] If the foam content in the inner drum falls within the first range, the washing program is controlled to enter the defoaming washing process. During the defoaming washing process, the motor drives the inner drum to rotate at a second speed, which is less than the first speed. The first current foam content is obtained, and it is determined whether the first current foam content meets the end condition of the defoaming washing process. If it does, the washing of the clothes to be washed is completed. If it does not, the defoaming washing process continues until the end condition of the defoaming washing process is met.

[0125] Specifically, if the foam content in the inner drum falls within the first range, it indicates a high foam content. Therefore, the washing program needs to enter a defoaming cycle, in which the motor drives the inner drum to rotate at a second speed. It's understandable that to improve the efficiency of foam removal in the inner drum, the washing program's efficiency can be increased by reducing the inner drum's rotation speed, increasing the total washing time at the second speed, or increasing the time per revolution of the inner drum. Alternatively, the washing efficiency can be improved by altering the heating element's heating cycle.

[0126] It should be noted that during the process of determining the foam content range in the inner drum using the first fitted parameters, the inner drum operates at the first rotation speed. After obtaining the first fitted parameters, the inner drum switches from the first rotation speed to the fourth rotation speed. Since the second rotation speed is lower than the first rotation speed, and the inner drum has already slowed down to the fourth rotation speed, if the washing program enters the defoaming control program, the rotation speed of the inner drum needs to be further reduced, thus reducing the rotation speed of the inner drum from the fourth rotation speed to the second rotation speed. Therefore, the fourth rotation speed is lower than the first rotation speed, and the fourth rotation speed is higher than the second rotation speed. The second rotation speed can be 20-30 revolutions per minute.

[0127] If, after the inner drum rotates at the second speed for a certain period of time during the defoaming control process, the first current foam content in the inner drum is detected to be lower than the preset foam content threshold, it indicates that the first current content meets the defoaming washing process. At this time, the foam content in the inner drum is low or close to zero, so the washing program can be ended and the washing of the clothes to be washed can be completed. If the first current content does not meet the defoaming washing process, it indicates that the foam content in the inner drum is still high, and the washing process needs to continue until the first current content is lower than the preset foam content threshold.

[0128] 206. If the foam content in the inner drum is in the third range, the washing program is controlled to enter the normal washing program, in which the motor drives the inner drum to rotate at the third speed during the normal washing program.

[0129] If the foam content in the inner drum is in the third range, the washing program is controlled to enter the normal washing program. In the normal washing program, the motor drives the inner drum to rotate at a third speed, which is greater than the first speed. The second current foam content is obtained, and it is determined whether the second current foam content meets the end condition of the normal washing program. If yes, the washing of the clothes to be washed is completed. If not, the normal washing process continues until the end condition of the normal washing process is met.

[0130] Specifically, if the foam content in the inner drum is in the third range, it indicates that there is little or no foam in the inner drum, and the washing program can enter the normal washing program. In the normal washing program, the motor drives the inner drum to switch from the first speed to the third speed. The third speed is greater than the first speed, and the third speed can be 40-55 rpm. Since the third speed is greater than the first speed, when the first speed is 35 rpm, the third speed can be 40 rpm; when the first speed is 45 rpm, the third speed can be 55 rpm. The inner drum can rotate in the third periodic switching mode at the third speed. The switching sequence of the third periodic switching mode can be clockwise rotation for 10-15 seconds, stop rotation for 1-5 seconds, counterclockwise rotation for 10-15 seconds, stop rotation for 1-5 seconds, and maintain the logic of alternating clockwise and counterclockwise periodic switching. The third periodic switching mode has a shorter rotation time and a shorter stop time compared to the second periodic switching mode.

[0131] If, after the inner drum rotates at the third speed for a certain period of time during the normal control process, the second current content of foam in the inner drum is detected to be lower than the preset foam content threshold, it means that the second current content meets the normal washing process. At this time, the foam content in the inner drum is low or close to zero, so the washing program can be ended and the washing of the clothes to be washed can be completed. If the second current content does not meet the normal washing process, it means that the foam in the inner drum still needs to be further eliminated until the first current content is lower than the preset foam content threshold, so as to improve the washing effect.

[0132] Of course, when the inner drum rotates at the third speed, the target washing time for that rotation can be obtained. If the target washing time is longer than the preset target washing time, the washing program is completed; if the target washing time is shorter than the preset target washing time, the inner drum continues to rotate at the third speed to wash the clothes. The target washing time is the washing time from the start of the inner drum rotating at the third speed to the current washing time, and the target washing time can be 10-20 minutes.

[0133] 207. If the foam content in the inner drum is in the second range, then obtain the second fitting parameter and control the washing program to switch to the washing process corresponding to the second fitting parameter.

[0134] If the foam content in the inner drum is within the second range, it indicates that the foam content in the inner drum is in the undetermined stage. At this time, it is necessary to obtain the initial water level of the inner drum, multiple second time values ​​of the inner drum rotating within a second preset time, and multiple first water levels corresponding to the multiple second time values, wherein one second time value corresponds to one first water level. The initial water level, multiple second time values, and multiple first water levels are fitted to obtain a second fitting formula, wherein the second fitting formula includes at least a second fitting parameter. If the second fitting parameter is less than or equal to a third preset threshold, the washing program is controlled to enter the defoaming washing process; if the second fitting parameter is greater than the third preset threshold, the washing program is controlled to enter the normal washing process.

[0135] Specifically, the initial water level W1 of the inner cylinder is obtained. The initial water level W1 is half or close to the height of the lifting ribs. For example, if the height of the lifting ribs is 30mm, the initial water level is 15-30mm; or if the height of the lifting ribs is 50mm, the initial water level can be 25-50mm. At this time, the inner cylinder rotates at the fourth speed. After the inner cylinder switches from the fourth speed to the first speed and maintains a stable speed, multiple second time values ​​T2 of the inner cylinder rotation within a second preset time period and multiple first water levels W2 corresponding to the multiple second time values ​​T2 are obtained. The first water level W2 can be close to the height of the lifting ribs or higher than the height of the lifting ribs. For example, if the height of the lifting ribs is 30mm, the first water level can be 30-35mm; or if the height of the lifting ribs is 50mm, the first water level can be 50-55mm. In this process, a second time value T2 and a first water level W2 are collected every second, such as (W21, T21), (W22, T22)...(W2n, T2n), etc. To improve detection accuracy, at least 10 second time values ​​T2 and first water level W2 can be acquired every second as sample data.

[0136] Multiple second time values ​​T2 and multiple first water level values ​​W2 are used as discrete data. Combined with the initial water level W1, a linear fit is performed using the least squares method to obtain the linear fitting formula W2 = K2 * T2 + W1 for the first water level W2 and the second time value T2. Here, K2 is the second fitting parameter and the slope of the second fitting formula. Since the water in the inner drum is absorbed by the clothes during the washing process, the first water level W2 gradually decreases; therefore, the second fitting parameter K2 is negative. It can be understood that if the first water level W2 decreases rapidly during the washing process, i.e., the second fitting parameter K2 is smaller and the slope is steeper, it indicates that the clothes have more foam and require more water for washing. Therefore, the foam content in the inner drum can be further determined using the second fitting parameter K2.

[0137] If the second fitting parameter K2 is less than or equal to the third preset threshold, it indicates that there is a lot of foam in the inner drum, and the washing program needs to be controlled to enter the defoaming washing process; if the second fitting parameter is greater than the third preset threshold, it indicates that there is little or no foam in the inner drum, and the washing program needs to be controlled to enter the normal washing process.

[0138] 208. The washing of the laundry is complete.

[0139] After the washing cycle of the clothes is completed, you can proceed with the draining cycle, spin-drying cycle, etc., to finish washing the clothes.

[0140] As can be seen from the above, in this embodiment, if the washing program of the washing machine is started, the motor is controlled to drive the inner drum to rotate at a fourth speed, and the initial power information of the motor is obtained; when the motor drives the inner drum to switch from the fourth speed to the first speed, the first power information of the motor and the first time information of the inner drum rotation are obtained; the initial power information, the first power information, and the first time information are fitted to obtain a first fitting formula, wherein the first fitting formula includes a first fitting parameter; according to the first fitting parameter, the foam content range in the inner drum is determined; if the foam content range in the inner drum is the first range, the washing program is controlled to enter the defoaming washing process, wherein the motor drives the inner drum to rotate at a second speed in the defoaming washing process; if the foam content in the inner drum is the third range, the washing program is controlled to enter the normal washing program, wherein the motor drives the inner drum to rotate at a third speed in the normal washing program; if the foam content in the inner drum is the second range, the second fitting parameter is obtained, and the washing program is controlled to switch to the washing process corresponding to the second fitting parameter; the washing of the clothes to be washed is completed. This embodiment improves the accuracy of foam detection by judging the fitting parameter in the fitting formula, thereby improving the washing effect.

[0141] To facilitate better implementation of the laundry control method of this application, this application also provides a laundry control device. Please refer to... Figure 3 , Figure 3 This is a schematic diagram of a first structural embodiment of the washing control device provided in this application.

[0159] If the first fitting parameter is less than the second preset threshold, the foam content range in the inner cylinder is the third range, wherein the foam content in the first range is greater than the foam content in the third range.

[0168] In some embodiments, the washing control device 300 may further include a second fitting module, which may be used for:

[0169] The initial water level of the inner cylinder, multiple second time values ​​of the inner cylinder rotating within a second preset time, and multiple first water levels corresponding to the multiple second time values ​​are obtained, wherein one second time value corresponds to one first water level.

[0170] The initial water level, multiple second time values, and multiple first water level values ​​are fitted together to obtain a second fitting formula, wherein the second fitting formula includes at least the second fitting parameters.

[0171] If the second fitting parameter is less than or equal to the third preset threshold, the washing program is controlled to enter the defoaming washing process.

[0172] If the second fitting parameter is greater than the third preset threshold, the washing program will enter the normal washing process.

[0173] In some embodiments, the first acquisition module 301 can also be used for:

[0174] If the washing machine's washing program is started, water is introduced into the inner drum until the inner drum reaches the initial water level, and the motor is controlled to drive the inner drum to rotate at the fourth speed. The average power of the motor during the third preset time when the inner drum rotates at the fourth speed is the initial power information. The first water level is higher than the initial water level, the fourth speed is less than the first speed, and the fourth speed is greater than the second speed.

[0175] In some embodiments, the washing control device 300 may further include a switching module, which may be used for:

[0176] Get the duration of time the inner drum has not been replenished with water after reaching the initial water level and the current washing duration of the washing program;

[0177] If the time without water replenishment exceeds the preset time without water replenishment, or if the current washing time exceeds the preset washing time, the control motor will drive the inner drum to switch from the fourth speed to the first speed.

[0178] All of the above technical solutions can be combined in any way to form optional embodiments of this application, and will not be described in detail here.

[0179] As can be seen from the above, the washing control device 300 provided in this embodiment, when the washing program of the washing machine is started, acquires the initial power information of the motor through the first acquisition module 301; when the motor drives the inner drum to rotate at a first speed, acquires the first power information of the motor and the first time information of the inner drum rotation through the second acquisition module 302; fits the initial power information, the first power information, and the first time information through the first fitting module 303 to obtain a first fitting formula, wherein the first fitting formula includes first fitting parameters; based on the first fitting parameters, the foam content range in the inner drum is determined by the determination module 304; based on the foam content range, the washing program is controlled by the control module 305 to execute the washing process corresponding to the foam content range, so as to wash the clothes to be washed. This embodiment improves the accuracy of foam detection by judging the fitting parameters in the fitting formula, thereby improving the washing effect.

[0180] Accordingly, this application also provides a washing machine, which can be a vented washing machine, a heat pump washing machine, or a condenser washing machine, etc. Figure 4 As shown, Figure 4This is a schematic diagram of the structure of a washing machine provided in an embodiment of this application. The washing machine 400 may include an inner drum 401 and a motor 402. Of course, the washing machine 400 may also include other structural components, such as an outer drum, a rotating shaft, and drum bearings (not shown in the figure), which are not specifically limited here.

[0181] The inner drum 401 is used to hold the clothes to be washed. The motor 402 drives the inner drum 401 to rotate, which in turn causes the clothes to rotate, creating friction between the clothes and the inner wall and lifting ribs of the inner drum 401, thus achieving the washing effect.
