Description

Technical Field

[0001] This invention relates to the field of clothing processing technology, and specifically provides a clothing processing device and its control method. Background Technology

[0002] Washing machines are becoming increasingly popular in homes due to their convenience, and most households now have one. Modern washing machines typically have multiple standard washing programs, usually designed for different types of clothing. These programs consider both the type of clothing and the desired washing effect to determine the appropriate standard washing program for each type.

[0003] Currently, when washing clothes, people usually select a washing program based on the type of clothing they are putting in. Each washing program includes a default water level, which is either used directly or adjusted manually by the user based on the amount of clothing. However, the water level determined in this way may not be suitable due to factors such as the type, quantity, and size of the clothing, resulting in poor washing performance and a reduced user experience.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the method of determining the washing water level in the prior art is not accurate enough, resulting in poor washing effect.

[0006] In a first aspect, the present invention provides a control method for a garment processing device, the garment processing device including a housing and a garment processing tub disposed within the housing, the control method comprising: acquiring multiple weight values ​​of clothes to be washed placed in the garment processing tub within a preset time period after the garment processing device is started and before water is introduced; sorting the multiple weight values ​​according to the acquisition time of each weight value; calculating the difference between two adjacent weight values; comparing the absolute value of each difference with the magnitude of a preset value; selectively controlling the garment processing device to operate a shaking mode according to a first comparison result; determining target washing parameters based on the weight values ​​and / or the number of times the garment processing device operates the shaking mode; and controlling the garment processing device to operate the target washing parameters.

[0007] In a preferred embodiment of the above control method, the target washing parameters include a target washing water level. The step of "determining the target washing parameters based on the weight value and / or the number of times the garment processing device operates the shaking mode" further includes: determining the target washing water level based on the weight value and / or the number of times the garment processing device operates the shaking mode.

[0008] In the preferred embodiment of the above control method, the step of "selectively controlling the clothing processing device to operate in a shaking mode according to the first comparison result" further includes: if the absolute value of at least one of the differences is greater than or equal to the preset value, then controlling the clothing processing device to operate in a shaking mode.

[0009] In the preferred embodiment of the above control method, the step of "controlling the clothing processing equipment to operate in a shaking mode" further includes: controlling the clothing processing drum to first run at a first speed for a first duration, and then run at a second speed for a second duration; wherein, the first speed is less than the second speed, and the first duration is less than the second duration.

[0010] In a preferred embodiment of the above control method, the control method further includes: before controlling the clothing processing device to run the shaking mode, determining whether the clothing processing device has run the shaking mode during the current operation; if the clothing processing device has already run the shaking mode, then the first duration of controlling the clothing processing device to run the shaking mode this time is greater than the second duration of its previous operation of the shaking mode.

[0011] In a preferred embodiment of the above control method, the control method further includes: when controlling the clothing processing drum to run at the first speed and the second speed, the rotation direction of the clothing processing drum is the same.

[0012] In the preferred embodiment of the above control method, the step of "selectively controlling the clothing processing equipment to operate in a shaking mode according to the first comparison result" further includes: if the absolute value of all the differences is less than the preset value, then the clothing processing equipment is not controlled to operate in a shaking mode.

[0013] In the preferred embodiment of the above control method, the step of "determining the target washing water level based on the weight value and / or the number of times the clothing processing equipment runs the shaking mode" further includes: obtaining the number of times the clothing processing equipment runs the shaking mode during this operation; determining whether the number is greater than zero; if the number is zero, determining the target washing water level based on the multiple weight values; if the number is greater than zero, further determining the target washing water level based on the second comparison result of the number and the preset number and the weight value.

[0014] In the preferred embodiment of the above control method, the step of "determining the target washing water level based on the second comparison result and the weight value" further includes: if the number of times is greater than or equal to a preset number of times, the target washing water level is determined based on the weight value obtained after the last operation of the shaking mode by the clothing processing equipment; if the number of times is less than the preset number of times, the target washing water level is determined based on the weight value obtained last time.

[0015] In the technical solution of this invention, after the garment processing equipment is started but before water is introduced, multiple weight values ​​of the clothes to be washed are acquired within a preset time period. These weight values ​​are sorted according to the acquisition time of each value, and the difference between two adjacent weight values ​​is calculated. Then, based on a first comparison result between the absolute value of each difference and a preset value, the garment processing equipment is selectively controlled to operate a shaking mode. Target washing parameters are determined based on multiple weight values ​​and / or the number of times the garment processing equipment operates the shaking mode. The garment processing equipment is then controlled to operate according to the target washing parameters. This method determines whether to operate the shaking mode based on the distribution of the detected weight values, aiming to disperse the clothes through shaking when the weight distribution is uneven, thereby more accurately acquiring the weight of the clothes to be washed. Based on this, the target washing parameters are determined based on the relatively accurate detected weight values ​​and the number of times the garment processing equipment operates the shaking mode. The resulting target washing parameters are more accurate and more suitable for the clothes to be washed. Therefore, the garment processing equipment operating with these target washing parameters can achieve better washing results, effectively improving the user experience.

[0016] Furthermore, the target washing parameters include the target washing water level. In other words, the target washing parameters determined in this invention based on the weight value and the number of times the garment processing equipment operates the shaking mode are the target washing water level.

[0017] If the absolute value of at least one difference is greater than or equal to the preset value, it means that at least one of the previously obtained weight values ​​has a large deviation. This indicates that the previously obtained weight values ​​are not all accurate. In this case, the clothing processing equipment is controlled to run in the shaking mode in order to shake the clothes apart.

[0018] Before controlling the garment processing equipment to operate in the shaking mode, first determine whether the garment processing equipment has already operated in the shaking mode during this operation. If it has already operated in the shaking mode, it means that this is not the first time the shaking mode has been operated. The clumps of clothes in the garment processing drum may have been shaken apart or at least partially shaken apart. In this case, the first duration of the garment processing equipment operating in the shaking mode this time is longer than the second duration of the previous shaking mode operation, in order to achieve the purpose of shaking the clothes apart by operating the shaking mode as few times as possible.

[0019] Furthermore, when determining the target washing water level, the number of times the garment processing equipment ran the shaking mode is recorded. If this number is zero, it means the garment processing equipment did not run the shaking mode during this operation, and the obtained weight values ​​are relatively accurate. In this case, the target washing water level is determined based on the multiple weight values ​​obtained previously. If the number is greater than or equal to a preset number, it means the garment processing equipment ran the shaking mode more times, and most of the obtained weight values ​​are inaccurate. In this case, the target washing water level is determined based on the weight value obtained after the garment processing equipment last ran the shaking mode. If the number is less than a preset number, it means the garment processing equipment ran the shaking mode less times, and the final obtained weight value is relatively accurate. In this case, the target washing water level is determined based on the last obtained weight value. This method can determine a more suitable target washing water level, achieve better washing results, and effectively improve the user experience.

[0020] Secondly, the present invention also provides a garment processing device, which includes a control module for executing the control method described in any of the foregoing schemes.

[0021] It should be noted that the garment processing equipment has all the technical effects of the aforementioned control method, which will not be elaborated here. Attached Figure Description

[0022] The preferred embodiments of the present invention are described below using a pulsator washing machine as an example and in conjunction with the accompanying drawings, in which:

[0023] Figure 1 This is a flowchart of a control method for a pulsator washing machine according to an embodiment of the present invention;

[0026] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Although this embodiment uses a top-loading washing machine as an example, it is obviously applicable to other types of clothing handling equipment such as front-loading washing machines, washer-dryer combos, and dual-dryer machines.

[0027] It should be noted that in the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise expressly specified and limited, the terms "connected" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] Current methods for determining the washing water level often result in unsuitable levels, leading to poor washing performance and a reduced user experience. To address this, this invention selectively controls the operation of the garment handling device's shaking mode based on a first comparison between the absolute value of the difference between two adjacent weight values ​​after sorting and a preset value. Furthermore, it determines the target washing parameters based on multiple weight values ​​and the number of times the garment handling device operates the shaking mode. These target washing parameters are better suited to the clothes being washed, resulting in better washing performance and a significantly improved user experience.

[0029] In this invention, a pulsator washing machine includes a cabinet, a top cover on the top of the cabinet, a pulsator, a pulsator motor, and an inner tub serving as a clothes handling drum, all housed within the cabinet. When washing clothes in the pulsator washing machine, the top cover is opened, the clothes to be washed are placed into the inner tub, the top cover is then closed, and the pulsator washing machine is started. Driven by the pulsator motor, the pulsator rotates, agitating the washing water, detergent, and clothes in the inner tub through forward and reverse rotation. Under the mechanical action of the rotating pulsator and the chemical action of the detergent, the clothes are repeatedly agitated and rubbed, thereby achieving the purpose of removing stains and cleaning the clothes.

[0030] After the laundry is placed into the inner tub, it usually rests on the pulsator. When the pulsator motor drives the pulsator to rotate, the motor generates a certain operating current. The pressure of the laundry on the pulsator affects the operating current of the motor, as does the state of the laundry inside the inner tub (e.g., scattered or clumped). Thus, by detecting the operating current of the pulsator motor, the weight and specific state of the laundry inside the inner tub can be determined.

[0031] Specifically, by obtaining the operating current of the impeller motor at each of the N rated rotational speeds, and then according to the correspondence between the rated rotational speed, operating current, and load weight, the load weight corresponding to the operating current of the impeller motor at each rated rotational speed is obtained. Based on the N load weights, the weight of the clothes in the inner tub is determined.

[0032] In this invention, the pulsator washing machine also includes a control module, which can calculate the difference between two adjacent weight values ​​after sorting based on the acquisition time of each weight value, selectively control the pulsator washing machine to operate the shaking mode based on the first comparison result of the absolute value of each difference and the preset value, determine the target washing parameters based on the weight value and / or the number of times the pulsator washing machine operates the shaking mode, and also control the pulsator washing machine to operate the target washing parameters, etc.

[0033] It should be noted that this control module can be a control chip that is inherent in the pulsator washing machine itself, a controller specifically designed to execute the method of this application, or a functional module or unit of a general controller.

[0034] The following reference Figures 1 to 3 This paper describes possible implementations of the control method for the garment processing equipment of the present invention.

[0035] like Figure 1 As shown, in one possible implementation, the control method of the present invention includes:

[0036] S100: After the pulsator washing machine starts but before water enters, it acquires multiple weight values ​​of the clothes to be washed in the inner drum within a preset time period.

[0037] S101: Sort multiple weight values ​​according to the acquisition time of each weight value;

[0038] S102: Calculate the difference between two adjacent weight values;

[0039] S103: Compare the absolute values ​​of each difference with the preset values;

[0040] S104: Selectively control the pulsator washing machine to operate in a shaking mode based on the first comparison result;

[0041] S105: Determine the target washing parameters based on the weight value and the number of times the pulsator washing machine runs the tumbling mode;

[0042] S106: Controls the target washing parameters for the pulsator washing machine.

[0043] In S100, after the pulsator washing machine is started but before water is introduced, the laundry has been put into the inner tub. The pulsator washing machine has started but has not yet started to introduce water for washing. Within a preset time period, multiple weight values ​​of the laundry in the inner tub are obtained by obtaining the working current of the pulsator motor and then determining the weight of the laundry.

[0044] It should be noted that the preset time period can be 30 seconds, 1 minute, 2 minutes, etc., and this embodiment does not limit the specific duration of the preset time period.

[0045] It should be noted that multiple weight values ​​can be obtained by continuous detection within a preset time period, or by obtaining the weight value of a garment to be washed at intervals, such as obtaining a weight value every 2 seconds, 3 seconds, or 5 seconds.

[0046] In S101, based on the multiple weight values ​​obtained in S100, each weight value was obtained at a different time. The multiple weight values ​​are then sorted according to their respective acquisition times. It should be noted that the sorting can be done from front to back according to the acquisition time, or from back to front according to the acquisition time.

[0047] In S102, based on the multiple weight values ​​sorted in S101, the difference between two adjacent weight values ​​is calculated, thus obtaining multiple differences. During the weight acquisition process, the pulsator rotates under the drive of the pulsator motor, which disturbs the laundry placed in the inner tub. This can cause the laundry to clump together or become tangled, resulting in deviations in the multiple weight values ​​acquired within a preset time period. Therefore, multiple differences can be obtained when calculating the difference between two adjacent weight values.

[0048] In S103, the absolute values ​​of the multiple differences obtained in S102 are compared with preset values.

[0049] In step S104, based on the first comparison result in S103, it can be determined whether the laundry inside the inner tub is clumped or tangled. If clumping or tangling occurs, the detected weight value will be inaccurate. Therefore, determining whether to control the pulsator washing machine to operate in the shaking mode based on the first comparison result in S103 ensures that the weight value of the laundry is obtained when it is being shaken inside the inner tub, thus achieving a more accurate weight reading. The specific process for determining whether the pulsator washing machine should operate in the shaking mode is described below and will not be repeated here.

[0050] In step S105, the target washing parameters are determined based on the accurate weight value obtained in the early stage and the number of times the pulsator washing machine runs in the tumbling mode. The target washing parameters determined in this way are better matched with the clothes to be washed and are more suitable for them. The specific method for determining the target washing parameters is described below and will not be repeated here.

[0051] In S106, the target washing parameters determined in S105 are controlled to operate the pulsator washing machine.

[0052] The above control method first selectively controls the pulsator washing machine to operate the tumbling mode based on the size of each weight value in order to obtain a more accurate weight value. Then, the target washing parameters are determined based on the weight value and the number of times the pulsator washing machine operates the tumbling mode. This allows for the determination of more suitable target washing parameters for the clothes to be washed, resulting in better washing effects and improved user experience.

[0053] It should be noted that the target washing parameters can also be determined based solely on the weight value or solely on the number of times the pulsator washing machine runs the tumbling mode.

[0054] In one possible implementation, the target washing parameters include a target washing water level. That is, in step S105 above, the target washing water level is determined based on the weight value and the number of times the pulsator washing machine operates in the tumbling mode. This allows for a more suitable target washing water level, ensuring that clothes are adequately wetted for a better washing effect while conserving water. Obviously, the target washing parameters can also include a target spin-stop ratio, target number of rinses, target rinse time, target washing time, etc. The following example uses the target washing water level as the target washing parameter, combined with the attached... Figure 2 and Figure 3 The possible implementations of the control method of the present invention will be described in detail below.

[0055] like Figure 2 As shown, in one possible implementation, the control method of the present invention further includes:

[0056] S200: Obtain multiple weight values ​​of the laundry placed into the inner drum;

[0057] S201: Sort multiple weight values ​​according to the acquisition time of each weight value;

[0058] S202: Calculate the difference between two adjacent weight values;

[0059] S203: Determine if the absolute value of the difference is greater than or equal to the preset value. If yes, execute S204; otherwise, execute S205.

[0060] S204: Controls the pulsator washing machine to operate in the shaking mode;

[0061] S205: Do not control the pulsator washing machine to operate in the shaking mode.

[0062] In S200, similar to S100 above, multiple weight values ​​of the laundry inside the inner tub are obtained by obtaining the operating current of the impeller motor and then determining the weight of the laundry.

[0063] In S201, similar to S101 above, the multiple weight values ​​obtained in S200 are sorted according to their respective acquisition times.

[0064] In S202, based on the multiple weight values ​​sorted in S201, the difference between two adjacent weight values ​​is calculated, thus obtaining multiple differences.

[0065] In S203, based on the multiple differences obtained in S202, it is determined whether the absolute value of any difference is greater than or equal to a preset value.

[0066] If the absolute value of at least one difference is greater than or equal to the preset value, it means that at least one of the multiple weight values ​​obtained in S200 has a large deviation. This indicates that these weight values ​​are not all accurate, and at least one weight value was obtained when the clothes to be washed were clumped and tangled. In this case, the pulsator washing machine is controlled to run the shaking mode, that is, S204 is executed, in order to shake the clothes to be washed apart by running the shaking mode.

[0067] After executing S204, meaning after the pulsator washing machine has finished operating in the tumbling mode, it returns to execute S200 to continue acquiring the weight values ​​of the clothes to be washed in the inner drum. Multiple weight values ​​are acquired within a preset time period. These weight values ​​are then sorted based on their acquisition time, and the difference between adjacent weight values ​​is calculated. If the absolute values ​​of all differences are less than a preset value, the pulsator washing machine is not controlled to operate in the tumbling mode. If the absolute value of at least one of the differences is greater than or equal to the preset value, the pulsator washing machine is controlled to operate in the tumbling mode, and the process returns to execute S200. This process is repeated until all differences are less than the preset value. It should be noted that the duration of a single tumbling mode cycle can be a fixed value or determined by technicians based on experiments, experience, calculations, etc., as detailed below.

[0068] If the absolute value of all the differences is not greater than or equal to the preset value, that is, if the absolute value of all the differences is less than the preset value, then the difference between the multiple weight values ​​obtained in S200 is relatively small. This means that these weight values ​​are relatively accurate and the laundry in the inner drum is not clumped or tangled. In this case, the pulsator washing machine is not controlled to run the shaking mode, that is, S205 is executed to save energy.

[0069] It should be noted that if the absolute value of all the differences is less than the preset value, the pulsator washing machine can be controlled to run the shaking mode once or multiple times.

[0070] By using the above control method, the washing machine is not controlled to run the shaking mode when the absolute value of all differences is less than the preset value, and the washing machine is controlled to run the shaking mode when the absolute value of at least one difference is greater than or equal to the preset value. In this way, the laundry inside the drum is in a dispersed state during the process of obtaining the weight value, so that a more accurate weight value can be obtained, while also saving energy.

[0071] In one possible implementation, when controlling the pulsator washing machine to operate in the shaking mode in S204, the inner tub is controlled to first operate at a first speed for a first duration, and then at a second speed for a second duration, wherein the first speed is less than the second speed, and the first duration is less than the second duration. That is, when operating the shaking mode, the inner tub is first controlled to operate at a lower speed for a shorter first duration, and then controlled to operate at a higher speed for a longer second duration. This, through the different speeds of the inner tub, effectively shakes apart clumps and tangles of laundry inside the inner tub. It should be noted that the first speed can also be greater than or equal to the second speed. Similarly, the first duration can also be greater than or equal to the second duration.

[0072] In one possible implementation, when the pulsator washing machine is controlled to operate in the shaking mode in S204, the inner tub rotates in the same direction at both the first and second speeds. That is, the clothes are shaken apart by controlling the inner tub to rotate sequentially in the same direction at the first speed for a first duration and then at the second speed for a second duration. During the rotation of the inner tub, the clothes inside also rotate with it. Based on a principle similar to centrifugal separation, and since the pulsator washing machine has not yet been filled with water, the clothes inside the inner tub are still dry. Different clothes experience significantly different centrifugal forces, thus separating any clumps or tangles of clothes inside the inner tub, achieving the purpose of shaking apart the clothes. Obviously, the rotation direction of the inner tub can also be different when operating at the first and second speeds.

[0073] In one possible implementation, before controlling the pulsator washing machine to run the shaking mode in S204, it is first determined whether the pulsator washing machine has run the shaking mode during this operation, and then the running duration of the shaking mode is controlled according to the determination result.

[0074] Specifically, if the shaking mode has not been used during this operation, it means that this is the first time the pulsator washing machine has been controlled to run the shaking mode. In this case, the inner drum will be controlled to rotate at the first speed for a first duration and then at the second speed for a second duration in accordance with the above control method to achieve the purpose of shaking the clothes.

[0075] If the shake-and-untangle mode has already been run, it means this isn't the first time it's been used. At least one shake-and-untangle session has already been run to separate tangled or knotted clothes. The tangled or knotted clothes in the drum may have already been separated, or at least partially separated. In this case, the first duration of the shake-and-untangle mode in this current cycle is longer than the second duration of the previous cycle. In other words, if multiple shake-and-untangle cycles have been run, the duration of each cycle increases with the number of cycles. The goal is to ensure that running the shake-and-untangle mode for a longer period effectively separates the clothes, eliminating the need for further cycles. This minimizes the number of shake-and-untangle cycles, achieving the desired effect with fewer cycles, thus shortening the overall duration of the shake-and-untangle mode, saving time and reducing energy consumption.

[0076] It should be noted that before controlling the pulsator washing machine to run the tumbling mode, it is not necessary to determine whether the pulsator washing machine has run the tumbling mode before. Instead, the inner tub can be directly controlled to rotate at the first speed for the first duration and at the second speed for the second duration. That is, no matter how many times the pulsator washing machine has run the tumbling mode, the first duration and the second duration are the same each time it runs.

[0077] It should be noted that the first and second durations of the swishing mode when the pulsator washing machine is running can be set by the user or predetermined by technicians based on experience, experiments, calculations, etc.

[0078] In one possible implementation, when the judgment result in S203 is that the absolute value of all differences is less than a preset value, it could mean that the absolute value of all differences obtained on the first attempt is less than the preset value, so the pulsator washing machine does not need to run the tumbling mode from the beginning. Alternatively, it could mean that the pulsator washing machine has run the tumbling mode multiple times to completely scatter the laundry so that the absolute value of all differences is less than the preset value, and it no longer needs to run the tumbling mode. In either case, the pulsator washing machine no longer needs to run the tumbling mode. Therefore, the target washing water level for this run of the pulsator washing machine is determined based on the weight value and the number of times the pulsator washing machine has run the tumbling mode, in order to obtain a better washing effect. See below for reference. Figure 3 This invention will illustrate possible ways to determine the target washing water level.

[0079] like Figure 3 As shown, in one possible implementation, the control method of the present invention further includes:

[0080] S300: Get the number of times the pulsator washing machine runs in shake mode during this operation;

[0081] S301: Determine if the number of times is greater than zero. If yes, execute S303; otherwise, execute S302.

[0082] S302: Determine the target washing water level based on multiple weight values;

[0083] S303: Further determine whether the number of times is greater than or equal to the preset number of times. If yes, then execute S304; otherwise, then execute S305.

[0084] S304: Determine the target washing water level based on the weight value obtained after the pulsator washing machine has run its last shake mode.

[0085] S305: Determine the target washing water level based on the weight value obtained in the last acquisition.

[0086] In S300, when determining the target washing water level, the number of times the pulsator washing machine runs the shaking mode during this operation is first obtained.

[0087] In S301, based on the number of times obtained in S300, it is determined whether the number is greater than zero.

[0088] If the number is zero, it means that the pulsator washing machine did not run the shaking mode during this operation, and the clothes to be washed in the inner tub did not clump or tangle. This means that the multiple weight values ​​obtained in S100 or S200 are relatively accurate. At this time, the target washing water level is determined based on these weight values, which means that S302 is executed.

[0089] It should be noted that when determining the target washing water level based on multiple weight values, the average weight value obtained in S100 or S200 can be calculated first, and this average weight value can be used as a reference weight value. The target washing water level can then be determined based on this reference weight value. Alternatively, any weight value can be randomly selected from the multiple weight values ​​as the reference weight value, and the target washing water level can then be determined based on this reference weight value. Without departing from the basic principles of this application, those skilled in the art can flexibly choose the method for determining the reference weight value according to the specific application scenario, as long as the target washing water level can be accurately determined based on the reference weight value.

[0090] It should be noted that when determining the target washing water level based on a reference weight value, a washing water level database can be pre-built. This database stores various garment weights and their corresponding washing water levels. The reference weight value is matched with the weights in the washing water level database, and the washing water level corresponding to the successfully matched weight is determined as the target washing water level. Alternatively, a lookup table can be pre-built, where different weights correspond one-to-one with washing water levels. The reference weight value is compared with the weights in this lookup table, and the washing water level corresponding to the matching weight is determined as the target washing water level. Obviously, other methods can also be used to determine the target washing water level. Without departing from the basic principles of this application, those skilled in the art can flexibly choose the specific method for determining the target washing water level according to the specific application scenario, as long as a suitable washing water level can be determined.

[0091] If the count is greater than zero, then it is further determined whether the count is greater than or equal to the preset count, that is, S303 is executed.

[0092] If the number of cycles is greater than or equal to the preset number, it indicates that the washing machine has run the tumbling mode too many times, resulting in a high proportion of inaccurate weight values. In this case, the target washing water level is determined based on the weight value obtained after the washing machine's last tumbling mode run. This means executing S304 to determine the target washing water level based on a weight value that accurately reflects the weight of the clothes to be washed, thereby obtaining a more suitable washing water level. It should be noted that the weight value obtained in S304 can be one or more.

[0093] It should be noted that the specific process of determining the target washing water level in S304 based on the weight value obtained after the pulsator washing machine runs the last shake mode is roughly similar to the specific process of determining the target washing water level in S302 based on multiple weight values ​​in S100 or S200. Alternatively, a baseline weight value can be determined first, and then the target washing water level can be determined by pre-building a washing water level database or a reference table. To avoid redundancy, this will not be elaborated here.

[0094] If the number of times is less than the preset number, it means that the pulsator washing machine is running the shaking mode, but it runs less often and eventually shakes the clothes in the inner drum. In other words, the final weight value obtained is relatively accurate. At this time, the target washing water level is determined based on the weight value obtained last time, which means that S305 is executed.

[0095] It should be noted that the specific process of determining the target washing water level based on the last obtained weight value in S305 is roughly similar to the specific process of determining the target washing water level based on multiple weight values ​​in S100 or S200 in S302. It can also be determined by pre-building a washing water level database or a lookup table, etc. To avoid redundancy, it will not be described in detail here.

[0096] By using the above control method, the target washing water level is determined based on the most accurate and fewer weight values. This allows for the determination of a more suitable target washing water level and the achievement of better washing results, while reducing the amount of statistical calculations and lowering the hardware requirements for clothing processing equipment, thus effectively improving the user experience.

[0097] It should be noted that in S303 above, when the number of times is greater than zero, it is not necessary to further compare the number of times with the preset number of times; instead, the target washing water level can be determined directly based on the weight value obtained the last time. Of course, when determining the target washing water level, it is also possible not to obtain the number of times the pulsator washing machine runs the shaking mode during this operation; instead, the target washing water level can be determined directly based on the weight value obtained the last time. Without departing from the basic principles of this application, those skilled in the art can flexibly choose the specific method for determining the target washing water level according to the specific application scenario, as long as a suitable washing water level for the clothes to be washed can be determined.

[0098] In summary, in the preferred embodiment of the present invention, by sorting multiple weight values ​​according to the acquisition time of each weight value, selectively controlling the pulsator washing machine to operate in a tumbling mode based on a first comparison result of the absolute value of the difference between each adjacent pair of weight values ​​and a preset value, and determining the target washing parameters based on the weight values ​​and / or the number of times the pulsator washing machine operates in the tumbling mode, the determined target washing parameters are more suitable for the clothes to be washed, and the pulsator washing machine can obtain better washing results when operating the target washing parameters. If at least one difference's absolute value is greater than or equal to the preset value, the pulsator washing machine is controlled to operate in the tumbling mode; if all differences' absolute values ​​are less than the preset value, the pulsator washing machine is not controlled to operate in the tumbling mode. This ensures the accuracy of the final obtained weight value and also saves energy. By determining the target washing water level based on the number of times the pulsator washing machine operates in the tumbling mode during this operation, and then based on the multiple obtained weight values, or based on the weight value obtained after the last tumbling mode operation, or based on the last obtained weight value, a more suitable target washing water level can be determined, resulting in better washing results.

[0099] In addition, the present invention also provides a garment processing device, which includes a control module for executing the control method described in any of the foregoing schemes.

[0100] It should be noted that the garment processing equipment has all the technical effects of the aforementioned control method, which will not be elaborated here.

[0101] Although the steps in the above embodiments are described in the above order, those skilled in the art will understand that in order to achieve the effect of this embodiment, different steps do not need to be executed in such order. They can be executed simultaneously (in parallel) or in reverse order. These simple changes are all within the protection scope of this application.

[0102] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
