Description

Technical Field

[0001] This application relates to the field of washing machine technology, and is not limited to a washing machine. Background Technology

[0002] With the improvement of living standards, washing machines have become an indispensable household appliance in modern families. Traditional washing machines generally use fixed washing programs to control water flow intensity. However, excessively high water flow intensity can easily cause excessive friction on clothes, leading to severe wear and tear. Therefore, how to reduce wear and tear on clothes during the washing process remains a technical problem that needs to be solved. Summary of the Invention

[0003] In view of this, the washing machine provided in this application embodiment can reduce the wear and tear on clothes and other laundry items during the washing process.

[0004] This application provides a washing machine, including:

[0005] Box;

[0006] A cylindrical body, disposed within the box, is used to hold laundry;

[0007] A lint filter is installed inside the drum to collect lint generated by the laundry during the washing process.

[0008] A gravity sensor is installed at the bottom of the lint filter device to detect the weight of the lint inside the lint filter device.

[0009] The washing machine also includes:

[0010] The controller is configured to:

[0011] While the washing machine is in the washing state, the target change in the weight of the lint in the lint filter device is obtained;

[0012] If the change in the target lint weight meets the adjustment conditions, adjust the water flow intensity of the washing machine.

[0013] In the above technical solution, since the weight change of lint in the lint filter device can reflect the degree of wear and tear on clothes and other laundry during the washing process, the higher the weight change of lint, the more severe the wear and tear on clothes and other laundry. Therefore, this solution can determine whether the water flow intensity adjustment conditions are met by the target lint weight change in the lint filter device during the washing process, so as to dynamically adjust the water flow intensity of the washing machine. This can not only reduce the wear and tear on clothes and other laundry during the washing process, but also more reasonably control the water flow intensity of the washing machine to ensure the washing effect.

[0014] In some embodiments, the controller is configured to adjust the water flow intensity of the washing machine when the target lint weight change meets the adjustment conditions, including:

[0015] When the target change in wire weight meets the adjustment conditions, the target water flow intensity corresponding to the target change in wire weight is determined according to a preset mapping relationship. The preset mapping relationship is the relationship between multiple preset threshold ranges of wire weight change and multiple preset water flow intensities. The target change in wire weight is within the target threshold range, and the multiple preset threshold ranges include the target threshold range.

[0016] The water flow intensity of the washing machine is adjusted to the target water flow intensity.

[0017] In the above technical solution, based on the relationship between multiple preset threshold ranges and multiple preset water flow intensities included in the preset mapping relationship, the target threshold range in which the target lint weight change is located can be quickly and accurately determined, and the corresponding target water flow intensity can be determined based on the target threshold range. This allows the washing machine controller to adjust the washing machine's water flow intensity to the target water flow intensity in a timely manner, thereby improving the efficiency of the washing machine in adjusting the water flow intensity and reducing the wear and tear on clothes and other laundry items as quickly as possible.

[0018] In some embodiments, the controller is configured to determine the target water flow intensity corresponding to the target wire chip weight change according to a preset mapping relationship when the target wire chip weight change meets the adjustment conditions, including:

[0019] When the change in the weight of the target wire debris is within the target threshold range, the target water flow intensity corresponding to the change in the weight of the target wire debris is determined according to the preset mapping relationship.

[0020] In the above technical solution, when the change in the weight of the target lint is determined to be within the target threshold range, it means that the change in the weight of the target lint meets the adjustment conditions, that is, the water flow intensity of the washing machine needs to be adjusted. Then, the target water flow intensity corresponding to the change in the weight of the target lint can be quickly determined through the preset mapping relationship, thereby improving the efficiency of the washing machine in adjusting the water flow intensity.

[0021] In some embodiments, the plurality of preset threshold ranges are negatively correlated with the plurality of preset water flow intensities.

[0022] In the above technical solution, multiple preset threshold ranges for the change in lint weight in the preset mapping relationship are negatively correlated with multiple preset water flow intensities. This means that the higher the change in lint weight, the lower the corresponding water flow intensity, which can reduce the wear and tear on clothes and other laundry items; conversely, the lower the change in lint weight, the higher the corresponding water flow intensity, which can improve the washing effect. Therefore, during the washing process, the water flow intensity of the washing machine is reasonably controlled according to the change in lint weight. When the change in lint weight is too high, the water flow intensity is reduced to reduce wear and tear; when the change in lint weight is too low, the water flow intensity is increased to improve the washing effect. In other words, this solution can reduce the wear and tear on clothes and other laundry items while ensuring the washing effect.

[0023] In some embodiments, at the initial moment when the washing machine is in the washing state, the water flow intensity of the washing machine is the largest among the plurality of preset water flow intensities.

[0024] In the above technical solution, when the washing machine is in the initial washing state, the washing machine operates with the maximum water flow intensity. This ensures that the washing machine can quickly dissolve the detergent with a high water flow intensity at the initial moment, so that the detergent can quickly penetrate into the clothes and other laundry items, allowing the detergent to exert its cleaning effect more quickly, thereby improving washing efficiency.

[0025] In some embodiments, the controller is further configured to:

[0026] Obtain multiple historical lint weights of a target type of laundry, wherein the multiple historical lint weights are obtained when the target type of laundry is in a washing state;

[0027] If the weight of multiple historical chipping threads is less than the preset chipping thread weight, the multiple preset threshold ranges in the preset mapping relationship are corrected.

[0028] In the above technical solution, when the weight of lint from multiple historical data is less than the preset lint weight when the target type of laundry is in the washing state, it indicates that the multiple preset threshold ranges for the change in lint weight corresponding to the target type of laundry in the preset mapping relationship are unreasonable. Therefore, by judging the relationship between the weight of multiple historical data and the preset lint weight to determine whether to correct the multiple preset threshold ranges in the preset mapping relationship, the preset threshold ranges corresponding to each type of laundry can be promptly detected and flexibly adjusted, making the preset threshold ranges more consistent with the actual change in lint weight during the washing process of each type of laundry. This improves the accuracy and reliability of judging whether to adjust the water flow intensity of the washing machine during the washing state.

[0029] In some embodiments, the controller is further configured to correct the plurality of preset threshold ranges in the preset mapping relationship when the plurality of historical chip weights are all less than a preset chip weight, including:

[0030] If the weight of each historical chip is less than the preset chip weight, the preset threshold range in the preset mapping relationship is corrected based on the weight of each historical chip.

[0031] In the above technical solution, the preset threshold range in the preset mapping relationship is corrected according to the weight of multiple historical lint corresponding to each type of laundry, so that the corrected preset threshold range is more consistent with the actual change of lint weight during the actual washing process of each type of laundry, thereby improving the reliability of the corrected preset threshold range.

[0032] In some embodiments, the plurality of preset threshold ranges include a first threshold range, a second threshold range, and a third threshold range, wherein the maximum value of the first threshold range and the minimum value of the second threshold range are the first threshold, the maximum value of the second threshold range and the minimum value of the third threshold range are the second threshold, and the maximum value of the third threshold range is the third threshold.

[0033] The controller is further configured to, when the weights of the plurality of historical chipping threads are all less than a preset chipping thread weight, correct the plurality of preset threshold ranges in the preset mapping relationship based on the plurality of historical chipping thread weights, including:

[0034] If all the historical chip weights are less than the preset chip weight, the first threshold is updated to the minimum value among the historical chip weights, the second threshold is updated to the average value among the historical chip weights, and the third threshold is updated to the maximum value among the historical chip weights.

[0035] In the above technical solution, updating the first and third thresholds to the minimum and maximum values ​​among multiple historical lint weights ensures accurate identification of whether water flow intensity needs adjustment even in the most extreme cases of high and low lint weight changes, avoiding misjudgments due to thresholds that are too high or too low, thereby improving the sensitivity of judging lint weight changes. Furthermore, updating the second threshold to the average value among multiple historical lint weights helps to accurately judge lint weight changes in most cases. It is evident that this solution improves the accuracy of the preset threshold range in the preset mapping relationship, thereby improving the accuracy and reliability of judging whether to adjust the washing machine's water flow intensity during washing.

[0036] In some embodiments, the washing machine further includes:

[0037] A motor is mounted on the drum body to drive the laundry inside the drum to tumble, and the target start-stop ratio of the motor corresponds to the target water flow intensity.

[0038] The controller is configured to adjust the water flow intensity of the washing machine to the target water flow intensity, including:

[0039] The motor is controlled to operate according to the target start-stop ratio, so that the water flow intensity of the washing machine is adjusted to the target water flow intensity.

[0040] In the above technical solution, since the motor-to-stop ratio directly affects the water flow intensity, when the motor runs according to the target motor-to-stop ratio, the washing water will be driven to form a water flow of the target water flow intensity. Therefore, by controlling the motor to run according to the target motor-to-stop ratio, the water flow intensity of the washing machine can be adjusted to the target water flow intensity more accurately.

[0041] In some embodiments, the washing machine further includes:

[0042] An output device, which is connected to the controller;

[0043] The controller is also configured to:

[0044] When the washing machine is in the washing state, the target weight of the lint in the lint filter device is obtained;

[0045] If the target lint weight is greater than or equal to the preset lint weight, the output device is controlled to output a prompt message. The prompt message is used to remind the user to clean the lint filter and / or to inquire whether the washing machine should be put into self-cleaning mode after the washing cycle ends.

[0046] In the above technical solution, a target lint weight greater than or equal to a preset lint weight indicates that the lint filter is full or excessive. An output device then sends a notification, allowing the user to promptly understand the lint accumulation in the filter and remind them to clean it. It can even prompt the user whether to put the washing machine in self-cleaning mode. Therefore, this solution can prevent lint buildup due to untimely cleaning of the filter, thus extending the washing machine's lifespan and preventing lint from re-contaminating laundry and affecting washing performance.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0057] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0058] It should be noted that the terms "first," "second," and "third" used in the embodiments of this application are used to distinguish similar or different objects and do not represent a specific ordering of objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permissible, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein. For example, without departing from the scope of this application, a first threshold range can be referred to as a second threshold range, and similarly, a second threshold range can be referred to as a first threshold range. The first threshold range and the second threshold range are different numerical ranges.

[0059] With the improvement of living standards, washing machines have become an indispensable household appliance in modern families. Traditional washing machines generally use fixed washing programs to control the water flow intensity. These fixed washing programs are designed to wash clothes according to a preset water flow intensity in order to quickly and effectively remove stains from clothes and achieve good washing results.

[0060] To achieve optimal washing results, traditional fixed washing programs typically use high water flow intensity. When the washing machine is running, the high water flow causes the clothes to tumble rapidly. However, excessively high water flow intensity can easily lead to excessive friction on the clothes, causing severe wear and tear, especially on thinner and softer fabrics. This can result in deformation, fading, pilling, and significantly reduce the lifespan of the garments. Therefore, how to reasonably control the water flow intensity of the washing machine to ensure washing effectiveness while minimizing wear and tear on clothes during the washing process remains a technical problem that needs to be solved.

[0061] Therefore, this application provides a washing machine including a cabinet, a drum, a lint filter, a gravity sensor, and a controller. The controller is configured to, when the washing machine is in a washing state, acquire the target lint weight change within the lint filter; and adjust the water flow intensity of the washing machine when the target lint weight change meets adjustment conditions. By dynamically adjusting the water flow intensity of the washing machine based on the lint weight change, this application embodiment can reasonably control the water flow intensity, thereby reducing wear and tear on clothes and other laundry items during the washing process.

[0062] To make the purpose and technical solution of this application clearer and more intuitive, the washing machine disclosed in this application will be described in detail below with reference to the accompanying drawings.

[0063] Please see Figure 1 , Figure 1 This is a schematic diagram of a washing machine disclosed in an embodiment of this application. Figure 1 The washing machine shown includes, for example, Figure 1 A schematic diagram of a drum washing machine is shown in (a) above, and as shown in... Figure 1 The schematic diagram of the pulsator washing machine shown in (b) is illustrated in this application. The internal structure and control flow of the washing machine proposed in this embodiment can be applied to... Figure 1 The type of washing machine shown is not limited in this application.

[0064] It should be noted that the washing machine provided in this application embodiment can have various implementation forms. For example, the washing machine can be a single-tub washing machine, a twin-tub washing machine, a triple-tub washing machine, etc., and this application does not limit it.

[0065] The internal structure and control process of the washing machine proposed in the embodiments of this application will be described in detail below.

[0066] As an example, please see Figure 2 , Figure 2 This is a schematic diagram of the structure of a washing machine disclosed in an embodiment of this application. Figure 2 The twin-tub washing machine shown includes: a cabinet 110, a drum 120, a lint filter 130, a gravity sensor 140, and a controller 150.

[0067] The drum 120 is located inside the housing 110 and is used to hold laundry. It can be understood that the first drum 120 is usually used to hold laundry such as clothes. Users can place the clothes to be washed inside the drum 120, and when the washing machine is started, the clothes inside the drum 120 can be washed.

[0068] A lint filter 130 is disposed inside the drum 120. The lint filter 130 is used to collect lint generated by laundry during the washing process. It can be understood that when the washing machine starts and enters the washing state, the drum 120 begins to rotate. The rotation of the drum 120 causes the laundry to tumble inside the drum 120. During the tumbling process, the laundry rubs against the drum 120, causing lint to be generated. The generated lint can be stored in the lint filter 130.

[0069] A gravity sensor 140 is located at the bottom of the lint filter 130 and is used to detect the weight of the lint inside the lint filter 130. It can be understood that after detecting the weight of the lint inside the lint filter 130, the gravity sensor 140 can send the weight of the lint to the controller 150.

[0070] The controller 150 is the control center of the washing machine. It connects all the components of the washing machine through various interfaces and lines. The controller 150 is used to control the operating status of the washing machine. That is to say, the controller 150 can control the washing machine to be in different operating states such as water intake, washing, rinsing, and spin-drying, so that the washing machine can complete the washing process.

[0071] It should be noted that the controller 150 can be set at any location on the washing machine. The controller 150 can be in the form of a control chip or a control device. This application does not limit this.

[0072] It should be noted that the washing machine disclosed in the embodiments of this application may also include Figure 2 Other components not shown in the image. Figure 2 The components shown should not be construed as limiting the washing machine disclosed in the embodiments of this application.

[0073] The above structural diagrams of the washing machine provide a convenient understanding of the structure of the washing machine disclosed in the embodiments of this application, as well as the functions of each component constituting the washing machine. Based on this, the control flow of the washing machine proposed in the embodiments of this application can be implemented by the controller 150. The control flow for adjusting the water flow intensity of the washing machine proposed in the embodiments of this application will be described in detail below.

[0074] For ease of description, the descriptions of the various components of the washing machine in the following text will no longer include the following: Figure 2 The labels for the components shown are exemplary; controller 150 is described as a controller, and lint filter 130 is described as a lint filter.

[0075] Please see Figure 3 , Figure 3 This is a control flowchart of a controller disclosed in an embodiment of this application. Figure 3 The control flow diagram shown includes the following steps:

[0076] Step 310: When the washing machine is in the washing state, the controller obtains the target lint weight change in the lint filter device.

[0077] In this embodiment, after the washing machine is started, the duration of the washing cycle is a preset washing time. This preset washing time can be a user-defined washing time or the washing time corresponding to the washing mode the washing machine is currently in. For example, the washing machine may include multiple washing modes such as mixed washing, mite removal washing, soaking washing, wool washing, down jacket washing, and quick washing. When the washing machine is running in any washing mode, each washing mode has a corresponding preset washing time. It should be noted that the preset washing time can be any length, and this application does not limit it.

[0078] In this embodiment, the target lint weight change is used to reflect the change in lint weight within the lint filter. When the washing machine is in the washing cycle, the gravity sensor inside the washing machine can detect the lint weight change within the lint filter at preset time intervals within a preset washing duration, and send the detected target lint weight change to the controller, so that the controller can obtain the target lint weight change within the lint filter. For example, assuming the preset washing duration T is 15 minutes and the preset time interval Δt is 5 minutes, then the gravity sensor will detect the lint weight change within the lint filter every 5 minutes. Within 15 minutes, the controller can obtain the value m of the target lint weight change detected by the three gravity sensors. Δt .

[0079] It should be noted that the preset time interval can be any set time interval, and each preset duration can be any duration corresponding to the preset time interval. This application does not limit this.

[0080] In some implementations, the controller acquires the target change in the weight of the lint within the lint filter, including: acquiring the target change in the weight of the lint within the lint filter at preset time intervals. It can be understood that the target change in lint weight is used to reflect the target lint weight change acquired at preset time intervals.

[0081] In some implementations, the change in target wire debris weight is the difference between the current wire debris weight in the wire debris filter at the current moment and the historical wire debris weight in the wire debris filter at the previous moment, and the time interval between the current moment and the previous moment is a preset time interval. For example, the current wire debris weight in the wire debris filter at the current moment is m. 实时 The weight of the historical wire debris in the wire debris filter at the previous moment was m. 初始 Then, the change in target chip weight m Δt Then it is m Δt =m 实时 -m 初始 .

[0082] Step 320: The controller adjusts the water flow intensity of the washing machine when the target lint weight change meets the adjustment conditions.

[0083] In this embodiment, the weight change of lint within the lint filter reflects the degree of abrasion on clothes and other laundry during washing. A higher lint weight change indicates more severe abrasion on the clothes and other laundry, suggesting the current water flow intensity of the washing machine is too high and needs to be reduced. Conversely, a lower lint weight change indicates less abrasion on the clothes and other laundry, allowing for improved washing performance by increasing the water flow intensity. Therefore, the controller determines whether the adjustment conditions are met by acquiring the target lint weight change. If the controller determines that the target lint weight change meets the adjustment conditions, it can adjust the water flow intensity of the washing machine. In other words, the adjustment conditions represent the conditions corresponding to adjusting the water flow intensity of the washing machine.

[0084] Optionally, the adjustment conditions may include whether the change in the target lint weight is greater than or equal to a first preset lint weight change threshold. That is, if the change in the target lint weight is greater than or equal to the first preset lint weight change threshold, it indicates that the change in the target lint weight is too high, meaning the change in target lint weight meets the adjustment conditions. This triggers the controller to reduce the water flow intensity of the washing machine to reduce wear and tear on clothes and other laundry during the washing process. It should be noted that the first preset lint weight change threshold can be any preset value, and this application does not limit it.

[0085] Optionally, the adjustment conditions may include whether the change in the target lint weight is less than a second preset lint weight change threshold. That is, if the change in the target lint weight is less than the second preset lint weight change threshold, it indicates that the change in the target lint weight is low, meaning the change in the target lint weight meets the adjustment conditions. This triggers the controller to increase the water flow intensity of the washing machine, as a higher water flow intensity improves the washing effect. It should be noted that the second preset lint weight change threshold can be any preset value, and this application does not limit it.

[0086] It should be noted that there are multiple scenarios where the change in the target lint weight meets the adjustment conditions. In other words, adjusting the water flow intensity of the washing machine includes various scenarios such as reducing the water flow intensity of the washing machine or increasing the water flow intensity of the washing machine. This application does not limit this.

[0087] Optionally, the adjustment conditions may include whether the change in the target lint weight is within a preset threshold range for lint weight change. That is, if the change in the target lint weight is within the preset threshold range, it indicates that the change in the target lint weight meets the adjustment conditions, triggering the controller to adjust the water flow intensity of the washing machine. It should be noted that the preset threshold range can be any preset numerical range, and this application does not limit it.

[0088] In some implementations, the controller adjusts the water flow intensity of the washing machine by adjusting various control parameters such as the drum's rotation speed, the spin-to-stop ratio, and the water flow direction. Specifically, a higher rotation speed results in a faster drum rotation, increasing the water flow intensity and velocity within the drum; conversely, a lower rotation speed results in a slower drum rotation, decreasing the water flow intensity and velocity. A higher spin-to-stop ratio results in a longer drum rotation time, increasing the water flow intensity and velocity; conversely, a lower spin-to-stop ratio results in a shorter drum rotation time, decreasing the water flow intensity and velocity.

[0089] In some implementations, the controller is further configured to: acquire the washing duration of the washing machine in the washing state; and control the washing machine to enter the rinsing state if the washing duration is equal to a preset washing duration. It can be understood that if the washing duration is less than the preset washing duration, the washing machine will continue to be in the washing state.

[0090] As can be seen, by implementing the embodiments of this application, the change in the target weight of lint in the lint filter device during the washing process is used to determine whether the water flow intensity adjustment conditions are met, so as to dynamically adjust the water flow intensity of the washing machine. This not only reduces the wear and tear on clothes and other laundry items during the washing process, but also allows for more reasonable control of the water flow intensity of the washing machine to ensure the washing effect.

[0091] Through the above steps, one can basically understand the control process proposed in this application embodiment to dynamically adjust the water flow intensity by the change in the weight of wire debris.

[0092] The following section details the implementation method for dynamically adjusting water flow intensity based on changes in wire debris weight. Please refer to [link to relevant documentation]. Figure 4 , Figure 4 This is a control flowchart of another controller disclosed in an embodiment of this application.

[0093] like Figure 4 The control flow diagram shown includes the following steps:

[0094] Step 410: When the washing machine is in the washing state, the controller obtains the target lint weight change in the lint filter device.

[0095] Other implementations of step 410 can be found in step 310 above, and will not be repeated here.

[0096] Step 420: When the change in the weight of the target wire debris meets the adjustment conditions, the controller determines the target water flow intensity corresponding to the change in the weight of the target wire debris according to the preset mapping relationship.

[0097] In this embodiment, the preset mapping relationship is the relationship between multiple preset threshold ranges of wire chip weight change and multiple preset water flow intensities. It can be understood that each threshold range has a corresponding water flow intensity, and different threshold ranges correspond to different water flow intensities. For example, the preset mapping relationship between multiple preset threshold ranges of wire chip weight change and multiple preset water flow intensities can be referred to Table 1. As shown in Table 1, Table 1 includes the mapping relationship between each preset threshold range and the preset water flow intensities.

[0098] Table 1

[0099] Threshold range Water flow intensity <![CDATA[0≤m Δt <M1]]> S1 <![CDATA[M1≤m Δt <M2]]> S2 <![CDATA[M2≤m Δt <M3]]> S3

[0100] Where, m Δt This represents the change in the weight of the wire chips; 0 ≤ m Δt <M1, M1≤m Δt <M2, M2≤m Δt <M3 represents multiple different threshold ranges for the change in the weight of the wire debris, and M1<M2<M3; S1, S2, and S3 are multiple different water flow intensities, and S1>S2>S3.

[0101] It should be noted that the preset threshold ranges for the change in wire weight and the preset mapping relationship between the preset water flow intensities can be set by those skilled in the art according to actual needs, and this application does not limit this.

[0102] In some implementations, multiple preset threshold ranges in the preset mapping relationship are negatively correlated with multiple preset water flow intensities. This means that the higher the change in lint weight, the lower the corresponding water flow intensity, which can reduce the wear and tear on clothes and other laundry items; conversely, the lower the change in lint weight, the higher the corresponding water flow intensity, which can improve the washing effect. For example, please refer to Table 1 above, where M1 < M2 < M3, indicating that 0 ≤ m Δt <M1, M1≤m Δt <M2, M2≤m Δt The range of changes in wire debris weight corresponding to <M3 increases sequentially, while S1>S2>S3 indicates that the higher the change in wire debris weight, the lower the corresponding water flow intensity.

[0103] By adopting this implementation method, the water flow intensity of the washing machine is reasonably controlled according to the change in the weight of lint during the washing process. When the change in the weight of lint is too high, the water flow intensity is reduced to reduce wear, and when the change in the weight of lint is too low, the water flow intensity is increased to improve the washing effect. In other words, the washing effect can be guaranteed while reducing the wear and tear on clothes and other laundry items.

[0104] In some implementations, the washing machine includes a storage module that stores preset mapping relationships for easy retrieval and retrieval at any time.

[0105] In some implementations, when the change in target lint weight meets the adjustment conditions, the controller determines the target water flow intensity corresponding to the change in target lint weight according to a preset mapping relationship. This includes: when the change in target lint weight is within a target threshold range, determining the target water flow intensity corresponding to the change in target lint weight according to the preset mapping relationship. The preset threshold ranges in the preset mapping relationship include the target threshold range. In this implementation, when the change in target lint weight is determined to be within the target threshold range, it indicates that the change in target lint weight meets the adjustment conditions, meaning the water flow intensity of the washing machine needs to be adjusted. Therefore, the preset mapping relationship allows for the rapid determination of the target water flow intensity corresponding to the change in target lint weight, thereby improving the efficiency of adjusting the water flow intensity of the washing machine.

[0106] It is understandable that the controller can determine which threshold range among multiple preset threshold ranges in the preset mapping relationship the change in the target wire debris weight falls within. If it is determined that the change in the target wire debris weight falls within the target threshold range, then the water flow intensity corresponding to the target threshold range can be determined as the target water flow intensity. For example, referring to Table 1 above, when the change in the target wire debris weight is between 0 and m... Δt <M1, M1≤m Δt <M2, M2≤m Δt If the value is less than any threshold range in M3, the corresponding threshold range is the target threshold range. Assume the target chip weight change is within the range of M1 ≤ m. Δt If the value is less than the threshold range of M2, then the target water flow intensity is S2.

[0107] In some embodiments, at the initial moment when the washing machine is in the washing state, the water flow intensity of the washing machine is the highest among a plurality of preset water flow intensities. For example, referring to Table 1 above, at the initial moment of the washing state, the washing machine can wash according to water flow intensity S1. By adopting this embodiment, when the washing machine is in the washing state at the initial moment, it operates with the maximum water flow intensity, ensuring that the washing machine can quickly dissolve the detergent with a higher water flow intensity at the initial moment. This ensures that the detergent can quickly penetrate into the clothes and other laundry items, allowing the detergent to exert its cleaning effect more quickly, thereby improving washing efficiency.

[0108] Step 430: The controller adjusts the water flow intensity of the washing machine to the target water flow intensity.

[0109] In some embodiments, the washing machine also includes a motor mounted on the drum, which is used to tumble the laundry inside the drum. It is understood that when the motor is running, it can cause the laundry inside the washing machine drum to tumble, and at the same time, it also causes the washing water inside the washing machine to fluctuate.

[0110] As an example, such as Figure 1 The drum washing machine shown in (a) includes a motor. When the motor starts running, it can drive the drum of the drum washing machine to rotate, thereby causing the laundry inside the drum to tumble and the washing water to ripple.

[0111] As another example, such as Figure 1 The pulsator washing machine shown in (b) includes a motor and a dial. The dial is located below the washing machine drum. When the motor starts running, the motor can drive the dial to rotate, thereby causing the laundry inside the washing machine drum to tumble and the washing water to ripple.

[0112] In some implementations, the motor's start-stop ratio and water flow intensity have a one-to-one correspondence; different start-stop ratios correspond to different water flow intensities, and the motor's start-stop ratio and water flow intensity are positively correlated. That is, by operating the motor at different start-stop ratios, the water flow intensity of the washing machine can be adjusted; the higher the motor's start-stop ratio, the greater the water flow intensity, and the lower the motor's start-stop ratio, the smaller the water flow intensity.

[0113] It should be noted that the relationship between the motor's start-stop ratio and the water flow intensity can be set by those skilled in the art according to actual needs, and this application does not limit this.

[0114] In some implementations, based on the correspondence between the motor's start-stop ratio and the water flow intensity, the controller can determine the target water flow intensity corresponding to the target start-stop ratio of the motor. After determining the target water flow intensity corresponding to the target start-stop ratio, the controller adjusts the water flow intensity of the washing machine to the target water flow intensity, including controlling the motor to operate at the target start-stop ratio to adjust the water flow intensity of the washing machine to the target water flow intensity. Using this implementation, since the start-stop ratio directly affects the water flow intensity, when the motor operates at the target start-stop ratio, the washing water will be driven to form a water flow of the target intensity. Therefore, by controlling the motor to operate at the target start-stop ratio, the water flow intensity of the washing machine can be adjusted to the target water flow intensity more accurately.

[0115] As can be seen, by implementing the embodiments of this application, the adjustment conditions for water flow intensity are determined based on the target change in lint weight within the lint filter during the washing process. This allows for dynamic adjustment of the washing machine's water flow intensity, which not only reduces wear and tear on clothes and other laundry items during washing but also enables more reasonable control of the water flow intensity to ensure optimal washing results. Based on the relationship between multiple preset threshold ranges and multiple preset water flow intensities included in the preset mapping relationship, the target threshold range where the target lint weight change falls can be quickly and accurately determined. The corresponding target water flow intensity is then determined based on this target threshold range, allowing the washing machine controller to promptly adjust the water flow intensity to the target level. This improves the efficiency of water flow intensity adjustment, thereby reducing wear and tear on clothes and other laundry items more quickly.

[0116] Please see Figure 5 , Figure 5 This is a control flowchart of another controller disclosed in an embodiment of this application. Figure 5 The control flow diagram shown includes the following steps:

[0117] Step 510: When the washing machine is in the washing state, the controller obtains the target lint weight change in the lint filter device.

[0118] Step 520: When the change in the weight of the target wire debris meets the adjustment conditions, the controller determines the target water flow intensity corresponding to the change in the weight of the target wire debris according to the preset mapping relationship.

[0119] Step 530: The controller adjusts the water flow intensity of the washing machine to the target water flow intensity.

[0120] As described in the foregoing embodiments, during the washing machine's operation in the washing state, the water flow intensity of the washing machine can be dynamically adjusted by the change in the target weight of the lint within the lint filter during the washing process. In other words, the water flow intensity of the washing machine can be continuously adjusted throughout the entire washing process. To better illustrate the implementation method of adjusting the water flow intensity of the washing machine throughout the entire washing process, please refer to the example provided. Figure 6 , Figure 6 This is a control flowchart of another controller disclosed in an embodiment of this application. Figure 6 The control flow diagram shown includes the following steps:

[0121] Step 610: At the initial moment when the washing machine is in the washing state, the controller controls the water flow intensity of the washing machine to the first water flow intensity.

[0122] In this step, at the initial moment when the washing machine is in the washing state, the controller can set the water flow intensity of the washing machine to the largest of a plurality of preset water flow intensities, that is, the controller controls the water flow intensity of the washing machine to the first water flow intensity. For example, at the initial moment of the washing state, the washing machine can use the water flow intensity S1 in Table 1 above as the first water flow intensity for washing.

[0123] Step 620: The controller acquires the first change in the weight of the lint in the lint filter device at preset time intervals.

[0124] In this step, during the washing machine's operation in the washing state, the controller can detect the change in lint weight within the lint filter device using a gravity sensor at preset time intervals. That is, the first change in lint weight within the lint filter device can be obtained within a first time period. For example, assuming a preset time interval Δt, a first time period of Δt1, and the first lint weight change obtained within the first time period Δt1 is m. Δt1 .

[0125] Step 630: The controller determines whether the change in the weight of the first piece of lint is within the second threshold range. If yes, proceed to step 640. If no, continue to step 610.

[0126] In this step, the controller can determine whether the change in the weight of the first piece of wire is within the second threshold range. If so, it means that the change in the weight of the first piece of wire meets the adjustment condition. For example, assume that the second threshold range is M1≤m in Table 1 above. Δt <M2, it can be determined whether the change in the weight of the first thread chip is within the range of M1≤m. Δt <M2 threshold range, if M1≤m Δt1 <M2 indicates the change in weight of the first thread chip, m. Δt1 If the adjustment conditions are met, the controller will continue to control the water flow intensity of the washing machine to the first water flow intensity S1, so that the washing machine continues to wash at the first water flow intensity S1.

[0127] Step 640: The controller determines the second water flow intensity corresponding to the first change in the weight of the wire debris according to the preset mapping relationship.

[0128] In this step, the controller can determine the first change in the weight of the wire chips, m, based on a preset mapping relationship. Δt1 The corresponding second flow intensity. For example, see Table 1 above, since M1≤m Δt1 If M2 < M2, then the change in weight of the first wire chip is m. Δt1 The corresponding second water flow intensity is S2.

[0129] Step 650: The controller controls the water flow intensity of the washing machine to the second water flow intensity.

[0130] In this step, after determining the second water flow intensity S2 corresponding to the first change in the weight of the lint, the controller can adjust the water flow intensity of the washing machine to the second water flow intensity S2.

[0131] Step 660: The controller acquires the second change in the weight of the lint in the lint filter device at preset time intervals.

[0132] In this step, during the washing machine's operation in the washing state, the controller can detect the change in lint weight within the lint filter device using a gravity sensor at preset time intervals. That is, within a second time period following a first time period, the second change in lint weight within the lint filter device can be obtained. For example, if the first time period is Δt2, the second change in lint weight obtained within the second time period Δt2 is m. Δt2 .

[0133] Step 670: The controller determines whether the change in the weight of the second piece of wire is within the third threshold range. If yes, proceed to step 680. If no, continue to step 650.

[0134] In this step, the controller can further determine whether the change in the weight of the second piece of wire is within the third threshold range. If so, it indicates that the change in the weight of the second piece of wire meets the adjustment conditions. For example, suppose the third threshold range is M2≤m in Table 1 above. Δt <M3 can be used to determine whether the change in the weight of the second thread chip is within the range of M2≤m. Δt <M3 threshold range, if M2≤m Δt2 <M3 indicates the change in weight of the second wire chip, m. Δt2 If the adjustment conditions are met, the controller will continue to control the water flow intensity of the washing machine to the second water flow intensity S2, so that the washing machine continues to wash under the second water flow intensity S2.

[0135] Step 680: The controller determines the third water flow intensity corresponding to the second change in the weight of the wire debris according to the preset mapping relationship.

[0136] In this step, the controller can determine the second chip weight change m according to the preset mapping relationship. Δt2 The corresponding third flow intensity. For example, see Table 1 above, since M2≤m Δt2 If M3 < M3, then the change in weight of the second wire chip is m. Δt2 The corresponding third water flow intensity is S3.

[0137] Step 690: The controller adjusts the water flow intensity of the washing machine to the third water flow intensity.

[0138] In this step, after determining the third water flow intensity S3 corresponding to the second change in lint weight, the controller can adjust the water flow intensity of the washing machine to the third water flow intensity S3.

[0139] It should be noted that, Figure 6 This is merely an example based on the preset mapping relationships in Table 1. If the preset mapping relationships include M23≤m Δt <M4, M4≤m ΔtThe controller can dynamically adjust the water flow intensity of the washing machine during the washing process by using the weight change of lint in the lint filter device obtained during the washing process and the preset mapping relationship at preset time intervals. If the adjustment conditions are met, the controller can determine the corresponding water flow intensity.

[0140] Other implementation methods for steps 510 to 530 can be referred to the content of steps 410 to 430 above, and will not be repeated here.

[0141] As described in the above embodiments, the controller can determine the target water flow intensity corresponding to the target change in lint weight based on the relationship between multiple preset threshold ranges of lint weight change and multiple preset water flow intensities in a preset mapping relationship, thereby controlling the water flow intensity of the washing machine to be adjusted to the target water flow intensity. However, the materials of each type of laundry differ, and if the target water flow intensity corresponding to the target change in lint weight is determined according to the same preset mapping relationship for each type of laundry, there may be deviations. Therefore, the following will combine... Figure 5 The following steps describe an implementation method for dynamically adjusting preset mapping relationships to obtain suitable preset mapping relationships for different types of laundry.

[0142] Step 540: The controller acquires multiple historical lint weights of the target type of laundry.

[0143] In this embodiment, the multiple historical lint weights are obtained while the target type of laundry is in a washing state. These multiple historical lint weights reflect the total weight of lint within the lint filter device across multiple historical washing states of the target type of laundry. It can be understood that, while the target type of laundry is in multiple historical washing states, the lint weight for each historical washing state can be obtained to obtain multiple historical lint weights corresponding to multiple historical washing states.

[0144] It should be noted that this application does not limit the number of historical lint weights. For example, it can be the lint weights from multiple historical washing cycles, such as 100 or 50 cycles.

[0145] In some implementations, the controller acquires multiple historical lint weights of the target type of laundry, including: acquiring multiple historical lint weights of the target type of laundry according to a preset duration or a preset number of consecutive washes. For example, the preset duration can be any duration, such as 30 days, which can acquire the historical lint weights of the target type of laundry under all washing conditions within 30 days; the preset number of consecutive washes can be any number, such as 50 consecutive washes, which can acquire the historical lint weights of the target type of laundry under 50 consecutive washes.

[0146] Step 550: When multiple historical chip weights are all less than the preset chip weight, the controller corrects multiple preset threshold ranges in the preset mapping relationship.

[0147] In this embodiment, if the weights of multiple historical lint samples of a target type of laundry during washing are all less than a preset lint weight, it indicates that multiple preset threshold ranges for the change in lint weight corresponding to the target type of laundry in the preset mapping relationship are unreasonable. Therefore, it can be determined whether to correct the multiple preset threshold ranges in the preset mapping relationship by judging the relationship between the multiple historical lint weights and the preset lint weight.

[0148] In some implementations, when multiple historical lint weights are all less than a preset lint weight, the controller corrects multiple preset threshold ranges in the preset mapping relationship. This includes: correcting the multiple preset threshold ranges in the preset mapping relationship based on the multiple historical lint weights when multiple historical lint weights are all less than the preset lint weight. By employing this implementation, the preset threshold ranges in the preset mapping relationship are corrected based on multiple historical lint weights corresponding to each type of laundry, making the corrected preset threshold ranges more consistent with the actual lint weight changes during the washing process of each type of laundry, thus improving the reliability of the corrected preset threshold ranges.

[0149] In some implementations, multiple preset threshold ranges include a first threshold range, a second threshold range, and a third threshold range. The maximum value of the first threshold range and the minimum value of the second threshold range are the first threshold; the maximum value of the second threshold range and the minimum value of the third threshold range are the second threshold; and the maximum value of the third threshold range is the third threshold. For example, referring to Table 1 above, the first threshold range can be 0 ≤ m. Δt <M1, the second threshold range is M1≤m Δt <M2, the third threshold range is M2≤m Δt <M3, where the first threshold is M1, the second threshold is M2, and the third threshold is M3.

[0150] Optionally, when multiple historical chip weights are all less than a preset chip weight, the controller adjusts multiple preset threshold ranges in the preset mapping relationship based on the multiple historical chip weights. This includes: updating the first threshold to the minimum value among the multiple historical chip weights, updating the second threshold to the average value among the multiple historical chip weights, and updating the third threshold to the maximum value among the multiple historical chip weights. For example, since M1 < M2 < M3, assume the multiple historical chip weights include M1, M2, M3, M4...M n It can be M1, M2, M3, M4...M n The minimum value in the range is used as the first threshold after correction, and M1, M2, M3, M4...M n The average value is used as the corrected second threshold, and M1, M2, M3, M4...M n The maximum value in the range is used as the corrected third threshold.

[0151] By adopting this implementation method, the first threshold and the third threshold are updated to the minimum and maximum values ​​among multiple historical lint weights, respectively. This ensures that even in the most extreme cases of high or low lint weight changes, it can still accurately identify whether the water flow intensity needs to be adjusted, avoiding misjudgments due to thresholds that are too high or too low, thereby improving the sensitivity of judging lint weight changes. Furthermore, updating the second threshold to the average value among multiple historical lint weights helps to accurately judge lint weight changes in most cases. It is evident that this implementation method improves the accuracy of the preset threshold range in the preset mapping relationship, thereby improving the accuracy and reliability of judging whether to adjust the washing machine water flow intensity during washing.

[0152] As can be seen, by implementing the embodiments of this application, determining whether the water flow intensity adjustment conditions are met by measuring the target lint weight change within the lint filter during the washing process, and dynamically adjusting the water flow intensity of the washing machine, not only can the wear and tear on clothes and other laundry be reduced during washing, but the water flow intensity can also be controlled more rationally to ensure washing results. By determining whether to correct multiple preset threshold ranges in the preset mapping relationship by judging the relationship between multiple historical lint weights and preset lint weights, the preset threshold ranges corresponding to each type of laundry can be promptly identified and flexibly adjusted. This makes the preset threshold ranges more consistent with the actual lint weight changes during the washing process of each type of laundry, thereby improving the accuracy and reliability of determining whether to adjust the washing machine's water flow intensity during washing.

[0153] To enhance the personalization of washing machines, the following will combine... Figure 7 An introduction will be provided. Please see below. Figure 7 , Figure 7 This is a control flowchart of another controller disclosed in an embodiment of this application. Figure 7 The control flow diagram shown includes the following steps:

[0154] Step 710: When the washing machine is in the washing state, the controller obtains the target lint weight change in the lint filter device.

[0155] Step 720: The controller adjusts the water flow intensity of the washing machine when the target lint weight change meets the adjustment conditions.

[0156] The implementation methods for steps 710 and 720 can be referred to the content of steps 310 to 320 above, and will not be repeated here.

[0157] Step 730: When the washing machine is in the washing state, the controller obtains the target weight of lint in the lint filter device.

[0158] In this embodiment, when the washing machine is in the washing state, the controller can obtain the target lint weight in the lint filter device in real time through a weight sensor. The target lint weight is used to reflect the total weight of lint accumulated in the lint filter device during the washing state.

[0159] Step 740: When the target shaving weight is greater than or equal to the preset shaving weight, the controller outputs a prompt message.

[0160] In this embodiment, a target lint weight greater than or equal to a preset lint weight indicates that the lint filter is full or excessively full of lint. When the lint filter is full or excessively full of lint, a prompt message is output to allow the user to promptly understand the lint accumulation status within the filter. For example, the preset lint weight is M. c When the weight of the target wire chip is detected to be greater than or equal to M c When this happens, a prompt message will be displayed.

[0161] In some implementations, a prompt message is used to remind the user to clean the lint filter, thus reminding the user to clean the lint inside the lint filter in a timely manner.

[0162] In other implementations, a prompt message is used to ask whether the washing machine should be put into self-cleaning mode after the washing cycle ends, so as to prompt the user whether the washing machine should be put into self-cleaning mode after the washing cycle ends.

[0163] Optionally, in response to a user's query, if the query indicates that the washing machine should enter self-cleaning mode after the wash cycle ends, then after the wash cycle concludes, the controller will put the washing machine into self-cleaning mode. In self-cleaning mode, the lint filter can be automatically cleaned, eliminating the need for manual cleaning by the user.

[0164] In some implementations, the washing machine also includes an output device connected to the controller. As an example, such as... Figure 2 The washing machine shown also includes an output device. The output device can be installed on the housing 110 and is connected to the controller 150. It should be noted that the output device can be installed at any position on the housing 110, and this application does not limit this.

[0165] Optionally, the output device can be any type of output device such as a display screen or a speaker. Using different types of output devices allows the washing machine to output prompt information in different ways. This application does not limit the type of output device. For example, the display screen can show the text "The lint filter is full, please clean the lint filter" and / or "The lint filter is full, do you want to automatically run the self-cleaning function after this wash cycle ends?", or the speaker can alternately output prompt sounds and verbally announce "The lint filter is full, please clean the lint filter" and / or "The lint filter is full, do you want to automatically run the self-cleaning function after this wash cycle ends?".

[0166] As can be seen, by implementing the embodiments of this application, the change in the target weight of lint within the lint filter during the washing process is used to determine whether the water flow intensity adjustment conditions are met. This allows for dynamic adjustment of the washing machine's water flow intensity, which not only reduces wear and tear on clothes and other laundry during washing but also allows for more reasonable control of the water flow intensity, ensuring optimal washing results. It also prevents lint buildup due to untimely cleaning of the lint filter, thus extending the washing machine's lifespan and preventing lint from re-contaminating laundry and affecting washing performance.
