Description

Technical Field

[0001] The present invention relates to the technical field of washing machines, and in particular to a dehydration control method, device, computer equipment and storage medium for a washing machine. Background Art

[0002] Load adjustment of a washing machine refers to controlling the inner drum in the washing machine to rotate in a corresponding manner according to a preset adjustment action, thereby adjusting the placement of the load (usually clothes, etc.) placed in the inner drum, reducing the eccentricity of the inner drum caused by the load during subsequent rotation, improving the stability of the rotation, and thus improving the efficiency of various operations of the washing machine, especially dehydration.

[0003] In the prior art, a fixed adjustment action is usually used, that is, regardless of the load conditions, the rotation method during load adjustment remains unchanged. When the load conditions are different, the effect of load adjustment will be different, resulting in a lower overall success rate of load adjustment, an increased risk of vibration and noise, and a reduced user experience.

[0051] like Figure 1 As shown, Figure 1 This is a schematic diagram of an application scenario of the dehydration control method for a washing machine in an embodiment of the present invention. The application scenario of the dehydration control method for a washing machine in an embodiment of the present invention includes a computer device 100 (a dehydration control device for a washing machine is integrated in the computer device 100), and a computer-readable storage medium corresponding to the dehydration control method for a washing machine is run in the computer device 100 to execute the steps of the dehydration control method for a washing machine.

[0052] It is understandable that Figure 1 The computer device in the application scenario of the dehydration control method of the washing machine shown, or the devices included in the computer device, does not constitute a limitation on the embodiments of the present invention. That is, the number of devices and types of devices included in the application scenario of the dehydration control method of the washing machine, or the number and types of devices included in each device, do not affect the overall implementation of the technical solution in the embodiment of the present invention, and can all be regarded as equivalent replacements or derivatives of the technical solution claimed to be protected in the embodiment of the present invention.

[0053] In the embodiments of the present invention, the computer device 100 may be a standalone device, or a network or cluster of devices.

[0056] It should be noted that Figure 1 The application scenario of the dehydration control method of the washing machine shown is only an example. The application scenario of the dehydration control method of the washing machine described in the embodiment of the present invention is to more clearly illustrate the technical solution of the embodiment of the present invention, and does not constitute a limitation on the technical solution provided by the embodiment of the present invention.

[0057] Based on the application scenario of the above-mentioned dehydration control method of a washing machine, an embodiment of the dehydration control method of a washing machine is proposed.

[0058] First, as Figure 2 As shown, in one embodiment, the present invention provides a dehydration control method for a washing machine, comprising:

[0059] Step 201, determining a first weight of a first initial load to be dehydrated in a washing machine;

[0060] The first initial load refers to the load with moisture obtained after washing in the washing machine, including clothes, shoes, hats or other objects;

[0061] Among them, the first weight can be determined by various weighing methods, such as manual input. Specifically, when the user puts the first initial load with dehydration into the inner drum of the washing machine, the user can simultaneously input the corresponding first weight through the input components provided by the washing machine, such as a touch screen, buttons, etc. It should be noted that in this method, the user puts in the first initial load with water, but the user more often puts in a dry load to be washed, that is, the user inputs the weight of the load to be washed. Since the water absorption capacity of the load is related to its specific composition, for example, down jackets and cotton jackets have stronger water absorption capacity, while cotton and linen clothes have weaker water absorption capacity, the user can also simultaneously input The specific composition type of the load (e.g., one down jacket, two pairs of cotton and linen shorts, two pure cotton T-shirts, etc.) is input, so that the washing machine can perform a comprehensive analysis based on the weight of the load and the specific composition type of the load. For example, a weighted processing is first performed based on the specific composition type and the corresponding water absorption capacity of each type to obtain the comprehensive water absorption capacity of the load to be washed, and then the first weight of the first initial load after washing is determined based on the comprehensive water absorption capacity. For another example, a pressure sensor can be used for weighing. A pressure sensor of reasonable specifications is installed on the bottom plate of the inner drum of the washing machine. After washing is completed, the parameters of the pressure sensor are read to calculate the first weight of the first initial load.

[0062] Step 202, determining a first adjustment action of a first initial load according to the first weight;

[0063] Among them, the adjustment action specifies the rotation mode of the inner cylinder, such as the starting rotation speed of the inner cylinder, the starting rotation speed maintenance time, the first transition rotation speed, the first transition acceleration from the starting rotation speed to the first transition rotation speed, the first transition rotation speed maintenance time, the second transition rotation speed, the second transition acceleration from the first transition rotation speed to the second transition rotation speed, the second transition rotation speed maintenance time, the eccentricity value detection speed, and the eccentricity value detection acceleration from the second transition rotation speed to the eccentricity value detection speed. That is, the adjustment action indicates that the inner cylinder needs to complete the rotation process of the above speed conditions once or multiple times. Specifically, the inner cylinder increases from the starting rotation speed to the first transition rotation speed at the first transition acceleration after the starting rotation speed maintenance time, and then increases to the second transition rotation speed at the second transition acceleration after the first transition rotation speed maintenance time, and finally increases to the eccentricity value detection speed at the eccentricity value detection acceleration after the second transition rotation speed maintenance time.

[0064] It should be noted that, among the above-mentioned speed conditions, the initial rotation speed, the initial rotation speed maintenance time, the first transition rotation speed, the first transition acceleration from the initial rotation speed to the first transition rotation speed, the first transition rotation speed maintenance time, the second transition rotation speed, the second transition acceleration from the first transition rotation speed to the second transition rotation speed, and the second transition rotation speed maintenance time are used to adjust the placement state of the load in the inner cylinder, that is, to adjust the eccentricity of the load; while the eccentricity value detection speed and the eccentricity value detection acceleration from the second transition rotation speed to the eccentricity value detection speed are used to detect the eccentricity value of the load after completing one load adjustment, so as to facilitate determining whether the load needs to be further adjusted eccentrically based on the eccentricity value of the load in the future;

[0065] Among them, multiple adjustment actions can be preset, and each adjustment action corresponds to a different weight. The larger the load weight, the larger the adjustment range of the required adjustment action, so that the load can be better adjusted; when the first weight is determined, the first adjustment action corresponding to the first weight can be determined from the multiple preset adjustment actions according to the first weight;

[0066] Step 203: performing an eccentric adjustment on the first initial load according to the first adjustment action to obtain a first target load;

[0067] After the first adjustment action is determined, a corresponding control signal can be sent to the motor according to the speed condition corresponding to the first adjustment action, so that the motor completes the rotation process corresponding to the speed condition;

[0068] It should be noted that the adjusted first target load means that the eccentricity value of the load is not greater than the preset first threshold value, wherein the preset first threshold value is related to the speed condition corresponding to the eccentricity value detection in the above-mentioned adjustment process and the speed condition corresponding to the dehydration process. If the speed condition corresponding to the eccentricity value detection and the speed condition corresponding to the dehydration process are consistent, mainly referring to the rotation speeds of the two, then the eccentricity value obtained based on the speed condition corresponding to the eccentricity value detection is basically consistent with the eccentricity value that will appear during the dehydration process. Therefore, the preset first threshold value at this time only needs to not exceed the maximum eccentricity value allowed during the dehydration process, for example, the preset first threshold value is slightly smaller than the maximum eccentricity value allowed during the dehydration process; in addition, if the speed condition corresponding to the eccentricity value detection and the speed condition corresponding to the dehydration process are consistent, for example, the rotation speed corresponding to the eccentricity value detection is half of the maximum rotation speed during the dehydration process, then the eccentricity value obtained based on the speed condition corresponding to the eccentricity value detection is half of the eccentricity value that will appear during the dehydration process. Therefore, the preset first threshold value at this time needs to not exceed half of the maximum eccentricity value allowed during the dehydration process. Similarly, if the speed condition corresponding to the eccentricity value detection and the speed condition corresponding to the dehydration process have other corresponding relationships, then the conversion can be performed according to the above principle, which will not be repeated here.

[0069] Step 204, dehydrating the first target load;

[0070] Among them, after the eccentricity adjustment, the placement state of the first initial load in the inner drum changes, that is, the first target load is obtained, and the eccentricity value of the first target load in the subsequent dehydration process is lower; usually, the washing machine includes pre-spinning and main dehydration performed successively, and the speed conditions corresponding to the inner drums of pre-spinning and main dehydration are different. In this embodiment, dehydrating the first target load can refer to pre-spinning, and of course it can also refer to main dehydration. It can be understood that if it refers to pre-spinning, the first initial load in this embodiment is the load obtained after washing, and if it refers to main dehydration, the first initial load in this embodiment is the load obtained after pre-spinning.

[0071] Through the above-mentioned dehydration control method of the washing machine, the weight of the load is first determined, and then the corresponding adjustment action is determined according to the weight, and finally the eccentric adjustment is performed based on the determined adjustment action, so that the adjustment action of the load adjustment is not unique. Since the weight can characterize most of the properties of the load, the adjustment effect corresponding to the adjustment action determined based on the weight is better, which ultimately improves the overall success rate of the load adjustment, reduces the risk of vibration and noise, and improves the user experience.

[0072] In one embodiment, determining a first adjustment action of the first initial load according to the first weight includes:

[0073] Get the preset adjustment action configuration table;

[0074] Among them, the adjustment action configuration table includes multiple sample adjustment actions and sample weight intervals corresponding to the sample adjustment actions, that is, each sample adjustment action corresponds to a sample weight interval, for example, the sample weight interval includes within 5 kg (first sample weight interval), 6 kg-7 kg (second sample weight interval), 7 kg-8 kg (third sample weight interval), 8 kg-9 kg (fourth sample weight interval), 9 kg-10 kg (fifth sample weight interval), 10 kg-11 kg (sixth sample weight interval), 11 kg-12 kg (seventh sample weight interval), 12 kg-13 kg (eighth sample weight interval), then the 13 kg load range is divided into eight sample weight intervals, each sample weight interval corresponds to a weight span of 1 kg; of course, in other embodiments, other division methods can also be used, for example, each weight interval can correspond to a weight span of 0.5 kg or a weight span of 2 kg, etc.;

[0075] determining a target weight interval in which the first weight lies;

[0076] For example, if the first weight is 10.3 kg, then based on the above example, the target weight range for the first weight can be determined to be 10 kg-11 kg, corresponding to the sixth sample weight range;

[0077] According to the target weight interval, the corresponding sample weight interval is matched in the adjustment action configuration table, and the sample adjustment action corresponding to the matched sample weight interval is set as the first adjustment action of the first initial load;

[0078] After the target weight interval is determined, the sixth sample adjustment action corresponding to the sixth sample weight interval may be set as the first adjustment action for the first initial load.

[0079] Through the form of weight intervals, multiple sample adjustment actions can be reasonably set according to the weight of the load, thereby improving the reusability of the sample adjustment actions in terms of load weight.

[0080] In one embodiment, the first adjustment action includes an early adjustment action and a late adjustment action, wherein the adjustment amplitude of the early adjustment action is smaller than the adjustment amplitude of the late adjustment action; and performing an eccentric adjustment on the first initial load according to the first adjustment action to obtain a first target load includes:

[0081] According to the previous adjustment action, the first initial load is eccentrically adjusted to obtain the first initial load after the previous adjustment;

[0082] The adjustment amplitude depends on the speed condition of the rotation mode corresponding to the adjustment action, that is, it can be understood that the speed condition of the rotation mode corresponding to the later adjustment action has a greater speed, acceleration and / or holding time than the earlier adjustment action;

[0083] Among them, different loads have different adjustment difficulties, such as the material of the load, etc. For example, if the friction between two specific components in the load is large or the hardness of a specific component is large (such as jeans), it is not easy to adjust; if the friction between two specific components is small or the hardness of a specific component is small (such as silk and satin clothes), it is easy to adjust; the early adjustment action with a small adjustment amplitude can well adjust the eccentricity of the load that is easy to adjust, so that the eccentricity value of the load can be quickly reduced to below the preset first threshold, but the early adjustment action is difficult to adjust the eccentricity of the load that is not easy to adjust. Similarly, the later adjustment action with a large adjustment amplitude can well adjust the eccentricity of the load that is easy to adjust and the load that is not easy to adjust, but the time and power consumed by the later adjustment action are higher than those of the early adjustment action. Therefore, in the actual implementation process, the early adjustment action with a small adjustment amplitude can be used for adjustment first;

[0084] If the eccentricity value of the first initial load after the previous adjustment is not greater than the preset first threshold, determining the first initial load after the previous adjustment as the first target load;

[0085] If the eccentricity value after the initial adjustment is below the preset first threshold, it means that the first initial load is an easily adjustable load, and the first target load can be directly obtained without further subsequent adjustment.

[0086] If the eccentricity value of the first initial load after the early adjustment is greater than the preset first threshold value, the eccentricity adjustment of the first initial load is continued according to the early adjustment action, and when it is detected that the early adjustment action reaches the preset adjustment condition, the eccentricity adjustment of the first initial load after the early adjustment is continued according to the late adjustment action until the eccentricity value of the adjusted first initial load is no greater than the preset first threshold value, and the adjusted first initial load is determined as the first target load;

[0087] Among them, if the eccentricity value after the preliminary adjustment is still not below the preset first threshold value, the preliminary adjustment action will continue to be used until the eccentricity value obtained is below the preset first threshold value, but the premise is that the preliminary adjustment action has not reached the preset adjustment condition. The preset adjustment condition represents the maximum limit to which the preliminary adjustment action can be executed. If the eccentricity value after adjustment is still not below the preset first threshold value after exceeding the limit, it means that the preliminary adjustment action cannot adjust the first initial load well, and it is necessary to replace it with a subsequent adjustment action with a larger adjustment amplitude to continue to adjust the eccentricity of the first initial load. Since the subsequent adjustment action can adjust the eccentricity of loads that are not easy to adjust well, it will inevitably make the eccentricity value of the adjusted first initial load below the preset first threshold value.

[0088] For each adjustment action, two adjustment actions with different adjustment amplitudes are further set to adapt to the load of all materials. The execution order of using the early adjustment action first and then the later adjustment action is adopted, which can improve the overall adjustment efficiency and reduce the overall adjustment power consumption.

[0089] In one embodiment, when it is detected that the pre-adjustment action reaches a preset adjustment condition, before continuing the step of eccentrically adjusting the first initial load according to the post-adjustment action, the dehydration control method of the washing machine further includes:

[0090] Detecting whether the adjustment duration of the previous adjustment action is greater than a preset duration threshold, and whether the eccentricity mean of the first initial load within the preset duration threshold is greater than a preset second threshold;

[0091] Since the preliminary adjustment action will be repeated multiple times during the actual execution process, the adjustment duration of the preliminary adjustment action is calculated in real time, that is, during the execution of the preliminary adjustment action, the interval between the current time and the start time of the first preliminary adjustment action is calculated in real time;

[0092] To improve adjustment efficiency, the initial adjustment action is allowed to be performed within a preset time threshold. Whether the initial adjustment action causes the eccentricity value of the first initial load to be below a preset first threshold within the preset time threshold is used to analyze whether the initial adjustment action is insufficient in adjusting the first initial load. In addition, further statistics are calculated to determine whether the average eccentricity value of the first initial load within the preset time threshold is greater than a preset second threshold to analyze whether the initial adjustment action is effective.

[0093] If the adjustment duration is greater than the preset duration threshold, and the eccentricity mean is greater than the preset second threshold, it is detected that the previous adjustment action has reached the preset adjustment condition;

[0094] Among them, if the eccentricity value of the first initial load cannot be made below the preset first threshold within the preset time threshold, it means that the adjustment ability of the early adjustment action on the first initial load is insufficient, or at least it can be determined that its adjustment efficiency is not high. It can be understood that after determining that the eccentricity mean value is greater than the preset second threshold, it is necessary to replace it with the later adjustment action. Therefore, the preset second threshold value must be greater than the preset first threshold value. If it is further determined that the eccentricity mean value of the first initial load is greater than the preset second threshold value, it means that the adjustment of the early adjustment action is basically ineffective and can be understood as invalid. If the early adjustment action is continued to be used, it may take a lot of time to make the eccentricity value of the first initial load below the preset first threshold value, or even the eccentricity value of the first initial load cannot be made below the preset first threshold value. At this time, only the later adjustment action can be replaced, that is, it is detected that the early adjustment action meets the preset adjustment condition, that is, the trigger condition for replacing the later adjustment action is obtained;

[0095] If the adjustment duration is not greater than the preset duration threshold, and / or the eccentricity mean is not greater than the preset second threshold, it is detected that the previous adjustment action does not meet the preset adjustment condition;

[0096] Among them, if the adjustment duration is not greater than the preset duration threshold, it means that the previous adjustment action can still be used. If the adjustment duration is greater than the preset duration threshold, but it is further determined that the eccentricity average of the first initial load is not greater than the preset second threshold, it means that although the adjustment ability of the previous adjustment action on the first initial load is insufficient, the adjustment still has a certain effect and is not completely ineffective. Therefore, considering the time and power consumption of the later adjustment action, the previous adjustment action can be continued to be tried until the eccentricity value of the first initial load is below the preset first threshold, that is, it is detected that the previous adjustment action does not meet the preset adjustment condition;

[0097] Among them, it should be noted that although the expression "and / or" is used in this step, it can be understood that there are actually only the above two types; that is, in the actual execution process, the adjustment duration is first detected, and only after the adjustment duration is greater than the preset duration threshold, the eccentricity mean of the first initial load within the preset duration threshold is further detected. Therefore, there will not be a situation where the adjustment duration is not greater than the preset duration threshold and the eccentricity mean of the first initial load within the preset duration threshold is greater than the preset second threshold.

[0098] By detecting the adjustment duration and the mean eccentricity, it is determined whether the previous adjustment action meets the preset adjustment conditions, so that the later adjustment action can be replaced more reasonably.

[0099] In one embodiment, determining a first weight of a first initial load to be spun in a washing machine includes:

[0100] The control motor drives the inner drum containing the first initial load to rotate forward and reverse;

[0101] Among them, first control the motor to rotate forward to the set speed, then stop running until the motor speed is zero, then control the motor to reverse to the set speed, then stop running until the motor speed is zero, and repeat the above steps multiple times;

[0102] Detecting a first motor parameter of the motor during forward rotation and a second motor parameter during reverse rotation;

[0103] The motor parameters include the armature current when the motor rotates to the set speed, the back electromotive force voltage value of the motor, and the output power of the motor;

[0104] determining a first weight of a first initial load based on the first motor parameter and the second motor parameter;

[0105] After obtaining the above parameters, calculation and analysis can be performed based on the armature current, the back electromotive force voltage value of the motor, and the output power of the motor when the motor rotates to the set speed to obtain the average output power, and the first weight of the first initial load can be determined based on the average output power.

[0106] The specific details of utilizing motor rotation to realize load weighing can be referred to the prior art and will not be described in detail here.

[0107] In one embodiment, before the step of determining the first weight of the first initial load to be dehydrated in the washing machine, the dehydration control method of the washing machine further includes:

[0108] According to the weighing adjustment action, the original load to be dehydrated is eccentrically adjusted to obtain a first initial load;

[0109] As mentioned above, using motor rotation to achieve load weighing requires controlling the motor to rotate forward and reverse to a set speed. When the inner drum rotates based on the set speed, a large eccentricity value may be generated due to the placement of the load in the inner drum, thereby affecting the weighing and generating noise. Therefore, when using this method for weighing, the original load needs to be eccentrically adjusted before weighing so that the eccentricity value of the adjusted original load is below a preset third threshold value, thereby obtaining a first initial load.

[0110] It should be noted that the weighing adjustment action is based on the same principle as the first adjustment action described above, the difference being that the speed conditions corresponding to the two are different.

[0111] Through weighing adjustment, the eccentricity of the original load can be adjusted before weighing, thereby obtaining a first initial load with an eccentricity below a preset third threshold value, thereby ensuring that subsequent weighing can be performed more reliably.

[0112] In one embodiment, dehydration includes pre-dehydration and main dehydration; dehydrating the first target load includes:

[0113] Pre-dehydrating the first target load to obtain a pre-dehydrated second initial load;

[0114] determining a second weight of a second initial load;

[0115] determining a second adjustment action for the second initial load based on the second weight;

[0116] According to the second adjustment action, the second initial load is eccentrically adjusted to obtain an adjusted second target load;

[0117] performing a primary dehydration on the second target load;

[0118] In the above embodiment, it has been mentioned that the dehydration of the first target load can be pre-dehydration or main dehydration; in this embodiment, both pre-dehydration and main dehydration are included. Specifically, after the pre-dehydration is completed, the obtained second initial load is eccentrically adjusted according to the processing steps of the first initial load, and finally the adjusted second target load is subjected to main dehydration.

[0119] The determination of the second weight is the same as that of the first weight, the determination of the second adjustment action is the same as that of the first adjustment action, and the specific steps of eccentric adjustment of the second initial load are the same as those of the first initial load, which will not be repeated here.

[0120] It should be noted that, since the speed conditions of pre-dehydration and main dehydration are different, the first weight and the second weight are the same (since the second initial load is obtained by pre-dehydration of the first target load, the second weight must be smaller than the first weight), and the speed conditions of the first adjustment action and the second adjustment action are also different.

[0121] As shown in Table 1 and Figure 3 As shown, in one embodiment, the present invention provides a dehydration control method for a washing machine, comprising:

[0122] Table 1 OOB adjustment action configuration table

[0123]

[0124] Among them, OOB in the table and figure can represent the eccentricity value;

[0125] In response to the dehydration instruction, detecting whether the weighing eccentricity value is greater than the threshold value A, if not, performing eccentricity adjustment using the eccentricity adjustment action AP until the weighing eccentricity value is no greater than the threshold value A;

[0126] Pre-weigh the load to obtain the weight WPi (where i represents the weight interval);

[0127] Detect whether the pre-release eccentricity of the load is greater than Bi. If not, use the eccentricity adjustment action APEi to adjust the eccentricity. During this process, detect the adjustment duration in real time. If the adjustment duration is greater than the preset duration threshold T, further detect the average eccentricity value within the preset duration threshold T. If the average eccentricity value is greater than the threshold Ci, use the eccentricity adjustment action APLi instead to perform eccentricity adjustment until the pre-release eccentricity of the load is no greater than the threshold Bi.

[0128] Pre-dewatering of the load;

[0129] After the pre-stripping is completed, continue to check whether the weighing eccentricity value is greater than the threshold value A. If not, use the eccentricity adjustment action AM to adjust the eccentricity until the weighing eccentricity value is no greater than the threshold value A;

[0130] Weigh the load to obtain the weight WMi (where i represents the weight interval);

[0131] Detect whether the main eccentricity of the load is greater than Di. If not, use the eccentricity adjustment action AMEi to adjust the eccentricity. During this process, detect the adjustment duration in real time. If the adjustment duration is greater than the preset duration threshold T, further detect the average eccentricity value within the preset duration threshold T. If the average eccentricity value is greater than the threshold Ei, use the eccentricity adjustment action AMLi to perform eccentricity adjustment until the main eccentricity of the load is no greater than the threshold Di.

[0132] Perform a main spin on the load.

[0138] Through the dehydration control device of the above-mentioned washing machine, the weight of the load is first determined, and then the corresponding adjustment action is determined according to the weight, and finally the eccentric adjustment is performed based on the determined adjustment action, so that the adjustment action of the load adjustment is not unique. Since the weight can characterize most of the properties of the load, the adjustment effect corresponding to the adjustment action determined based on the weight is better, which ultimately improves the overall success rate of the load adjustment, reduces the risk of vibration and noise, and improves the user experience.

[0141] In one embodiment, the dehydration control device of the washing machine further includes:

[0143] In one embodiment, the weight determination module is specifically used to control the motor to drive the inner drum containing the first initial load to rotate forward and reverse; detect the first motor parameters of the motor during forward rotation and the second motor parameters during reverse rotation; and determine the first weight of the first initial load based on the first motor parameters and the second motor parameters.

[0145] The weighing adjustment module is used to perform eccentric adjustment on the original load to be dehydrated according to the weighing adjustment action before the step of determining the first weight of the first initial load to be dehydrated in the washing machine to obtain the first initial load.

[0146] In one embodiment, dehydration includes pre-dehydration and main dehydration; the load dehydration module is specifically used to pre-dehydrate the first target load to obtain a second initial load after pre-dehydration; determine the second weight of the second initial load; determine the second adjustment action of the second initial load based on the second weight; based on the second adjustment action, perform an eccentric adjustment on the second initial load to obtain an adjusted second target load; and perform main dehydration on the second target load.
