Description

Technical Field

[0001] This application relates to the field of fabric processing equipment technology, and in particular to a dehydration control method, electronic equipment, and fabric processing equipment. Background Technology

[0002] During the spin cycle of a drum washing machine, it's necessary to detect the eccentricity of the load inside the drum. If the eccentricity is within acceptable limits, the spin cycle speed is increased. The eccentricity limit is determined by a control point that prevents displacement or drum collision when the eccentricity reaches 400 RPM. Generally, the maximum anti-eccentricity mass achievable by a drum washing machine at 400 RPM is approximately 1000g.

[0003] When users wash highly absorbent fabrics, such as a single baby cotton garment or a single cotton quilt, the weight of these fabrics increases from about 300g to about 2000g after washing due to their high water absorption rate. This is far greater than the maximum anti-eccentricity mass that can be achieved when the drum speed is set to 400. As a result, these types of fabrics cannot be effectively dehydrated according to the normal spin-drying program, which reduces the user's experience with the drum washing machine. Summary of the Invention

[0004] In view of this, this application provides a dehydration control method, electronic device, and fabric processing device to solve the problem that existing drum washing machines cannot properly dehydrate highly absorbent fabrics such as single infant cotton clothes or single cotton quilts, resulting in a poor user experience.

[0005] A first aspect of this application provides a dehydration control method applied to a fabric processing device, the fabric processing device including a fabric processing cylinder capable of dehydrating fabrics, the dehydration control method comprising:

[0006] The dehydration program is run, which includes multiple dehydration stages, each of which has a corresponding set of dehydration parameters. The maximum rotation speed of the fabric treatment drum in the next dehydration stage is greater than its maximum rotation speed in the previous dehydration stage.

[0007] Specifically, before executing the dehydration process to each of the dehydration stages, an array of dehydration parameters that meet the set requirements in the dehydration parameter set of the previous dehydration stage is used as the candidate dehydration parameters for the next dehydration stage, so as to determine the dehydration parameter set for the next dehydration stage during the execution of the next dehydration stage according to the candidate dehydration parameters.

[0008] In some embodiments, the plurality of dehydration stages includes a first dehydration stage;

[0009] Each of the aforementioned dehydration stages is configured with a corresponding set of dehydration parameters, including:

[0010] In the first dehydration stage, the fabric treatment drum is controlled to increase the speed according to the set dehydration rhythm;

[0014] In some implementations, the step of using the logical calculation results of multiple sets of correspondences as the dehydration parameter set in the first dehydration stage includes:

[0015] Logistic regression algorithm is used to determine the probability proportion of rotational speed and acceleration corresponding to each of the eccentricity value and the weighing value in multiple sets of correspondences;

[0016] The probability percentages calculated from multiple sets are used as the logical calculation results.

[0017] In some embodiments, the step of using an array of dehydration parameters that meet set requirements from the dehydration parameter set of the previous dehydration stage as candidate dehydration parameters for the next dehydration stage, so as to determine the dehydration parameter set for the next dehydration stage during the execution of the next dehydration stage based on the candidate dehydration parameters, includes:

[0018] The top M groups of dehydration parameters with the highest probability among all groups in the first dehydration stage are selected as candidate dehydration parameters for the next dehydration stage, where M ≥ 5.

[0019] In some implementations, when the total number of groups of dehydration parameters determined in any of the dehydration stages is less than M, the number of groups of dehydration parameters less than M is used as the alternative dehydration parameters for the next dehydration stage.

[0020] In some implementations, the execution order of the M groups of dehydration parameters among the alternative dehydration parameters in the next dehydration stage is random.

[0021] In some embodiments, the maximum rotational speed of the next dehydration stage is the sum of the maximum rotational speed of the previous dehydration stage and a set value.

[0022] In some embodiments, the dehydration control method further includes, prior to running the dehydration process:

[0023] Determine whether the fabric is a highly absorbent material;

[0024] If so, then execute the dehydration procedure.

[0025] In some embodiments, determining whether the fabric is a highly absorbent material includes:

[0027] The corresponding feature is used to characterize the load type information of the fabric under standard load water absorption.

[0028] In some embodiments, corresponding features of the fabric are used to characterize the size of the fabric;

[0029] The step of determining whether the fabric is a highly absorbent material based on the actual water absorption of the fabric before and after water ingress and the corresponding characteristics of the fabric includes:

[0030] Determine the difference between the actual water absorption and the standard load water absorption;

[0031] If the difference is greater than or equal to a set threshold, and the size of the fabric is less than a set value, and the weight of the fabric before water ingress is within a set range, then the fabric is determined to be the highly absorbent material fabric; the set threshold is N times the weight of the fabric before water ingress, where N≥3.

[0032] In some embodiments, the highly absorbent fabric includes at least infant cotton clothing.

[0033] In some embodiments, after the step of determining whether the fabric is a highly absorbent material and before the step of running the dehydration program, the dehydration control method further includes:

[0034] Control the washing water in the fabric treatment drum to drain to the empty drum water level.

[0035] In some embodiments, after the step of determining whether the fabric is a highly absorbent material and before the step of running the dehydration program, the dehydration control method further includes:

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0052] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0053] like Figures 1 to 2As shown, an exemplary embodiment of this application provides a dehydration control method that can be applied to a fabric processing device. The fabric processing device includes a fabric processing cylinder capable of dehydrating fabrics.

[0054] The fabric treatment equipment may include, but is not limited to, a washing machine, which may include, but is not limited to, a washer-dryer combo, or a washing and conditioning combo. For example, the washing machine may be a front-loading washing machine or a top-loading washing machine with drying or washing and conditioning functions; of course, the washing machine may also be other types of fully automatic washing machines. In this example and the examples below, the fabric treatment equipment is described using a front-loading washing machine as an example. Specifically, the dehydration control method includes the following steps:

[0055] Step S100: Run the dehydration program, which includes multiple dehydration stages. Each dehydration stage has a corresponding set of dehydration parameters. The maximum rotation speed of the fabric treatment drum in the next dehydration stage is greater than its maximum rotation speed in the previous dehydration stage.

[0056] Step S200: Before executing the dehydration process to each dehydration stage, the array of dehydration parameters that meet the set requirements in the dehydration parameter set of the previous dehydration stage is used as the candidate dehydration parameters for the next dehydration stage, so as to determine the dehydration parameter set of the next dehydration stage during the execution of the next dehydration stage according to the candidate dehydration parameters.

[0057] In step S100, in order to improve the dehydration efficiency and quality of highly absorbent fabrics such as infant cotton clothing, the dehydration process includes multiple dehydration stages. This allows for a gradual and slow dehydration process on the fabric in each stage, thereby gradually removing the moisture from the highly absorbent fabric and preventing problems such as drum collisions that are prone to occur when dehydrating this type of fabric.

[0058] Each dehydration stage has a corresponding set of dehydration parameters, and the maximum rotation speed of the fabric treatment drum in the next dehydration stage is greater than the maximum rotation speed of the fabric treatment drum in the previous dehydration stage.

[0059] In other words, each dehydration stage involves an acceleration process of the fabric processing drum, and the maximum speed of each stage is higher than the maximum speed of the previous stage.

[0060] In step S200, during the process of controlling and running each dewatering stage of the fabric processing drum, the control system of the fabric processing equipment uses an array of dewatering parameters that meet the set requirements from the previous dewatering stage as candidate dewatering parameters for the next dewatering stage before executing the dewatering program to each dewatering stage. Then, when the fabric processing drum is controlled to run the next dewatering stage using the candidate dewatering parameters, the set of dewatering parameters for the next dewatering stage is determined.

[0061] It should be noted that the control system of the fabric processing equipment can use existing control units, and no specific restrictions are made here.

[0062] For example, in the first dewatering stage of the fabric treatment drum, when the fabric treatment drum speeds up according to the corresponding dewatering rhythm, and the control system speeds up the fabric treatment drum to the first target speed, multiple dewatering parameters related to the speed of the fabric treatment drum during dewatering can be determined first, such as eccentricity value and weighing value. Then, using the weighing value corresponding to the eccentricity value and the corresponding relationship between the speed and acceleration, multiple sets of corresponding relationships between the weighing value corresponding to the eccentricity value and the corresponding speed and acceleration can be determined, and these multiple sets of corresponding relationships can be used as the dewatering parameter set of the fabric treatment drum in the first dewatering stage.

[0063] It should be noted that the corresponding weighing value and the corresponding rotation speed and acceleration of this eccentricity value can be used to characterize the distribution state of the fabric during the dewatering process. That is, the rotation speed and corresponding acceleration of the fabric treatment drum at this time can be used to represent the state change of the eccentricity value and weighing value of the fabric at this time.

[0064] When the maximum rotational speed of the fabric treatment drum reaches the first target rotational speed, the fabric treatment drum enters the next dehydration stage (such as the second dehydration stage). Since multiple sets of corresponding weighing values ​​and corresponding rotational speeds and accelerations are determined during the first dehydration stage, a set of dehydration parameters that meet the set requirements can be selected as the dehydration parameter set for the second dehydration stage. For example, the sets with the highest probability of occurrence among all the aforementioned sets of corresponding relationships can be selected as the dehydration parameters that meet the set requirements, and these sets (e.g., five sets) with the highest probability can be used as the dehydration parameter set for the second dehydration stage. The reason is that when the fabric processing drum dehydrates highly absorbent fabrics (such as infant cotton clothing), the fabric's unfolding state within the drum is constantly changing, and its distribution and weight are also constantly changing. Each time the eccentricity value of the fabric is obtained, the fabric processing drum will not experience problems such as drum collision. In other words, the fabric's distribution state at this time can adapt to and meet the distribution requirements of the fabric processing drum when dehydrating at the current rotation speed and acceleration. That is to say, the eccentricity value and weight value determined by the fabric's distribution state at this time represent that the fabric's unfolding state can adapt to the dehydration requirements, and this state has a relatively high probability of occurring in this dehydration stage. When the corresponding relationship determined at this time (i.e., the weight value corresponding to the eccentricity value and the corresponding relationship between the rotation speed and acceleration) can also be adapted for use in the next dehydration stage, it can also meet the dehydration requirements of the next dehydration stage.

[0065] Based on this, this example uses multiple sets of dehydration parameters that meet the requirements determined in the previous dehydration stage as the dehydration parameter set in the next dehydration stage. In other words, the dehydration parameters of multiple dehydration stages are logically controlled, so that highly absorbent fabrics (such as infant cotton clothing) can perform an efficient and effective dehydration process, gradually removing the wash water present in such fabrics. This effectively solves the problem of rapid dehydration of highly absorbent fabrics and improves the user experience.

[0066] like Figure 1 And refer to Figure 2 As shown, in some embodiments, the multiple dehydration stages include a first dehydration stage. During the first dehydration stage, the control system of the fabric treatment equipment controls the fabric treatment drum to increase its speed according to a set dehydration rhythm.

[0067] The first step in the dewatering process is the fabric distribution process, whose main parameters are the rotational speed and acceleration of the fabric processing drum. Following the distribution process, the fabric eccentricity detection process is performed, i.e., detecting the eccentricity value. Then, if the obtained eccentricity value meets the threshold for fabric weighing, the fabric is weighed, and a valid weight value is obtained. It should be noted that the threshold for the eccentricity value to meet the weighing requirement refers to a threshold built into the control system when controlling the fabric. This threshold can be determined based on the actual dewatering conditions of the fabric processing equipment and is not specifically limited here.

[0068] During the speed-up process, the dehydration rhythm can be set according to the following rules: The rotational speed of the fabric processing drum during fabric distribution begins to increase within the speed range [30, 40]. From this speed range [30, 40], the speed increases to the acceleration range [6, 42] for the eccentricity detection speed. The rotational speed of the fabric processing drum increases by 2 increments each time. The acceleration of the fabric processing drum is changed in increments of 6 increments, increasing to the maximum value of 42, and then restarting the cycle from the minimum value of 6.

[0069] During the aforementioned acceleration process, all sampled values ​​of the fabric treatment cylinder are acquired and recorded as it accelerates to the first target speed. These sampled values ​​include at least the eccentricity value of the fabric treatment cylinder and the weight value of the fabric.

[0070] The eccentricity value can be detected using existing eccentricity detection methods, which will not be elaborated here. The weight of the fabric can be measured using a weight sensor or by measuring the drive power and current change of the drive motor that rotates the fabric processing drum, which will not be elaborated here.

[0071] Then, multiple sets of correspondences between the rotational speed and acceleration corresponding to each eccentricity value and weighing value are determined, and the logical calculation results of the multiple sets of correspondences are used as the dehydration parameter set in the first dehydration stage.

[0072] In one example, the logical calculation results of multiple sets of correspondences can be performed using the following method:

[0073] The logistic regression algorithm is used to determine the probability proportion of the rotational speed and acceleration of the fabric processing cylinder corresponding to each eccentricity value and weighing value in each set of correspondences. It should be noted that the logistic regression algorithm used in this example can be an algorithm in the existing technology, which will not be elaborated here.

[0074] Then, the probability proportions of the rotational speed and acceleration of the fabric processing drum corresponding to each eccentricity value and weighing value in the multiple sets of calculated correspondences are used as the logical calculation results. In other words, the probability proportions of the rotational speed and acceleration of the fabric processing drum corresponding to each eccentricity value and weighing value in the multiple sets of correspondences calculated by the logistic regression algorithm are used as the dewatering parameter set of the fabric processing drum in the first dewatering stage.

[0075] Finally, the fabric treatment drum continues to dehydrate according to the set dehydration rhythm until it reaches the first target speed, after which it enters the next dehydration stage (i.e., the second dehydration stage). The first target speed can be set to 200 revolutions per minute (RPM), meaning the fabric treatment drum rotates 200 times per minute. During this first dehydration stage, the fabric treatment drum rotates slowly at the set dehydration rhythm, slowly dehydrating the highly absorbent fabric while simultaneously recording the fabric's distribution process in detail. This includes effectively recording various eccentricity values ​​and weight values, thereby determining the set of dehydration parameters for the fabric in the first dehydration stage.

[0076] In the second dehydration stage, the array of dehydration parameters that meet the set requirements from the dehydration parameter set of the previous dehydration stage is used as the candidate dehydration parameters for the next dehydration stage. This is to determine the dehydration parameter set for the next dehydration stage during the execution of the next dehydration stage based on the candidate dehydration parameters, including:

[0077] The top M groups of dehydration parameters with the highest probability among all groups in the first dehydration stage are selected as candidate dehydration parameters for the next dehydration stage, where M ≥ 5. That is, the 5 groups of dehydration parameters with the highest probability among all groups are selected as candidate dehydration parameters for the second dehydration stage. Then, the control system of the fabric processing equipment can effectively control the rotation speed and acceleration of the fabric processing drum in the second dehydration stage based on these 5 groups of dehydration parameters. This allows the fabric processing drum to effectively increase its current rotation speed and acceleration within the allowable range of eccentricity and weighing values, thereby ensuring effective dehydration of highly absorbent fabrics while preventing drum rotation and significant polarization.

[0078] During the second dehydration stage, after the rotational speed of the fabric treatment drum increases to the second target rotational speed, it enters the next dehydration stage, namely the third dehydration stage. The process of determining the dehydration rotational speed set in the third dehydration stage is the same as that of the second dehydration rotational speed set, which will not be described in detail here.

[0079] In some examples, when the total number of dehydration parameter groups determined in any dehydration stage is less than M (i.e., less than 5), the dehydration parameters with fewer than M groups are used as candidate dehydration parameters for the next dehydration stage. It should be noted that in this application, the number of dehydration parameter groups in the first dehydration stage is greater than 5.

[0080] Furthermore, in some examples, the execution order of the M groups of dehydration parameters among the alternative dehydration parameters in the next dehydration stage is randomized. For instance, based on all the dehydration parameters in the first dehydration stage, five groups of dehydration parameters in the second dehydration stage are determined to correspond to the rotational speed and acceleration of the fabric treatment drum corresponding to the eccentricity value and the weighing value, respectively: the first group, the second group, the third group, the fourth group, and the fifth group.

[0081] During the speed-up process of the fabric treatment drum in the second dehydration stage, the control system can randomly control the fabric treatment drum according to any one of the first, second, third, fourth and fifth groups, or it can perform logical control sequentially according to the order of the first, second, third, fourth and fifth groups.

[0082] It should be noted that during each dewatering stage of the fabric processing drum, once the drum's rotation speed reaches the target speed set for that stage, the control system will stop the drum, reducing its speed to zero. This utilizes the drum's rotational inertia during shutdown to continue dewatering the highly absorbent fabric. After the drum stops rotating in that dewatering stage, it will begin to increase its speed again by selecting five sets of dewatering parameters that meet the set requirements.

[0083] In some examples, the maximum rotational speed of the fabric treatment drum in the next dewatering stage is the sum of the maximum rotational speed of the previous dewatering stage and a set value. The set value can be an integer multiple of 10, such as two or three times the set value.

[0084] In a specific example, this setting is 20. That is, when the maximum speed set for the first dehydration stage is 200 rpm, the maximum speed for the next dehydration stage, the second dehydration stage, is 220 rpm, and the maximum speed for the third dehydration stage is 240 rpm.

[0085] After several stages of increasing speed during the dehydration process, once the fabric processing drum reaches the target speed, the process switches to normal dehydration. The target speed can be set to 400 rpm. This means that when the fabric processing drum reaches 400 rpm after multiple dehydration stages, it indicates that regardless of how the fabric processing drum is controlled, the distribution of the highly absorbent fabric will effectively meet the requirements for subsequent detection of eccentricity and weighing values. Furthermore, the fabric processing drum will not exhibit any significant polarization or collisions. After this point, normal dehydration at the increased speed can proceed.

[0086] like Figure 3 and Figure 4 As shown, and in combination Figure 1 and Figure 2 In some embodiments, the dehydration control method further includes the following steps before running the dehydration process:

[0087] Step S10: Determine whether the fabric is a highly absorbent material.

[0088] Step S11: If yes, then perform the dehydration process.

[0089] In step S10, the following identification method can be used in the process of identifying the type of fabric:

[0090] Based on the actual water absorption of the fabric before and after water ingress and the corresponding characteristics of the fabric, it is determined whether the fabric is a highly absorbent material. The corresponding characteristics of the fabric are used to characterize the load type information corresponding to the standard load water absorption.

[0091] In some examples, the difference between the fabric's actual absorbency and the standard load absorbency can be determined first. When this difference is greater than or equal to a set threshold, and the fabric's dimensions are smaller than the set value, and the fabric's weight before water ingress is within a set range, the fabric can be identified as a highly absorbent material. The set threshold is N times the fabric's weight before water ingress, where N is a value greater than or equal to 3. N can be an integer value of 3 or any value greater than 3.

[0092] In a specific example, the highly absorbent fabric is at least infant cotton clothing. It should be noted that infant cotton clothing is a special type of cotton clothing used by infants and children. Therefore, this type of infant cotton clothing will absorb a large amount of wash water during washing, so that the weight of the soaked infant cotton clothing can reach many times its own weight, such as 3 times or more.

[0093] In addition, the size of the infant cotton clothing is also specially designed, that is, smaller than the set value, which can be 50 cm, and the weight of such infant cotton clothing in a dry state is no more than 350g, that is, the set range is below 350g.

[0094] The process of determining the difference between the actual water absorption and the standard load water absorption includes:

[0095] Obtain the first weight value of the fabric before water intake. This first weight value is used to determine the corresponding standard load water absorption in the standard load water absorption information table.

[0096] The second weight value of the fabric after water ingress is obtained. During the water ingress stage, the water ingress flow rate and water level frequency value of the fabric treatment cylinder are obtained. When the water level frequency value reaches the set water level frequency value, the amount of water ingress into the fabric in the wet state is determined based on the water ingress flow rate, and the amount of water ingress is used as the second weight value of the fabric.

[0097] The water intake here is calibrated based on the water volume required when the same control water level is used. The load used is the national standard load, and the water absorption rate of the national standard load is fixed. Therefore, the water consumption is calibrated using national standard loads of different weight levels.

[0098] According to experimental tests, infant cotton clothing is a type of load with a dry load weight of 300g. When the water level is controlled at the same weight, the water consumption is much greater than that of this level.

[0099] The difference between the second weight value and the first weight value is taken as the actual water absorption, and the difference between the actual water absorption and the standard load water absorption is taken as the difference.

[0100] In other words, infant cotton clothing represents a category of clothing with high water absorption. This type of clothing should not exceed 50 cm in size, weigh no more than 350g when dry, and weigh no less than 1500g after washing.

[0101] During the washing process, before the water intake stage, the weight of the infant cotton clothing is measured. This weight is used to determine the standard load water level. During the water intake stage, when the set water level frequency value is reached, the actual water intake volume is obtained through the water flow sensor for that stage.

[0102] This water level frequency value is a standard value specifically used for this stage. Through testing, the water intake volume at this water level frequency was calibrated for different weights. Therefore, different weight ranges correspond to different water intake volumes. If the actual water intake volume obtained in this stage is greater than the standard water intake volume for that range, it indicates that the water absorption capacity of this load is greater than the standard load's water absorption capacity. Simultaneously, by combining the weight value of the clothing obtained before water intake, the corresponding characteristics of this type are found. If it matches the characteristics of infant and children's cotton clothing, a spin-drying process is then executed.

[0103] Among them, such as Figure 5 and combined Figure 2 and Figure 4 As shown, in some examples, after the fabric has been identified as a highly absorbent material and before the dehydration process is run, the dehydration control method further includes the following steps:

[0104] Step S20: Control the washing water in the fabric treatment drum to drain to the empty drum water level.

[0105] This step is to ensure that the fabric is not affected by the washing water in the fabric treatment drum during the subsequent dehydration process, thereby effectively improving the accuracy of the dehydration parameter set determination in each dehydration stage and improving the dehydration efficiency and quality of this type of infant cotton clothing.
