Description

Technical Field

[0001] This application relates to the field of laundry technology. More specifically, it relates to a pulsator washing machine and its control method. Background Technology

[0002] Top-loading washing machines are still widely used by the public due to their simple and convenient operation.

[0003] Currently, users typically use the default program (also known as the standard program) or select a program they prefer when using a top-loading washing machine. However, this can easily lead to a mismatch between the washing parameters and the clothes being washed, resulting in poor washing performance. Summary of the Invention

[0004] The pulsator washing machine and its control method provided in this application embodiment can increase the probability that the washing parameters for washing clothes match the clothes put in, thereby improving the washing effect of clothes.

[0005] In a first aspect, embodiments of this application provide a pulsator washing machine, comprising:

[0006] Box;

[0007] A cylindrical body is rotatably disposed within the housing, and the cylindrical body forms a washing chamber for placing a load.

[0008] A water inlet valve, connected to the cylinder, is configured to inject water into the cylinder.

[0009] A drain valve, connected to the cylinder, is configured to drain water from the cylinder.

[0010] The controller connected to the inlet valve and the drain valve is configured to:

[0011] Perform a first weighing task to obtain a first weight of the load in the cylinder; the first weighing task is configured to weigh the load.

[0012] Perform a second weighing task to obtain the second weight of the load in the cylinder; the second weighing task is configured to control the water inlet valve to open for a first preset time to weigh the load;

[0013] Perform a third weighing task to obtain the third weight of the load in the cylinder; the third weighing task is configured to control the drain valve to open for a second preset time to weigh the load;

[0014] Based on the first weight, the second weight, and the third weight, the description information of the load is determined; the description information includes the weight of the load, the saturated water content, and whether it is easy to float;

[0015] Based on the description information, cleaning parameters for cleaning the load are determined, and the load is cleaned based on the cleaning parameters.

[0016] In the above solution, by weighing the load three times, compared to the existing single weighing, the load's description information can be accurately determined. Based on the accurate description information, the corresponding cleaning parameters can be determined, thereby matching the load's cleaning parameters with the load itself. This reduces the probability of inadequate cleaning of the load due to mismatched cleaning programs or water levels, achieving more efficient and safer washing of the load and thus improving the user experience.

[0017] In some embodiments, the cleaning parameters include at least one of the following: cleaning program, cleaning water level, and dehydration sub-parameters;

[0018] The cleaning water level includes at least one of the following: washing water level, rinsing water level, and balancing water flow level.

[0019] In some embodiments, if the first weight is less than a first preset weight, the weight of the load is determined to be a low load; if the first weight is greater than or equal to the first preset weight and less than or equal to a second preset weight, the weight of the load is determined to be a medium load; if the first weight is greater than the second preset weight, the weight of the load is determined to be a high load.

[0020] If the second weight is less than the first weight, the load is determined to be a load that is easy to float; if the second weight is greater than or equal to the first weight, the load is determined to be a load that is not easy to float.

[0021] If the third weight is less than M times the first weight, the saturated moisture content of the load is determined to be low moisture content; if the third weight is greater than or equal to M times the first weight, and the third weight is less than or equal to N times the first weight, the saturated moisture content of the load is determined to be medium moisture content; if the third weight is greater than N times the first weight, the saturated moisture content of the load is determined to be high moisture content; where M is greater than N, and both M and N are greater than zero.

[0022] In the above scheme, by setting reasonable judgment conditions, the accuracy of identifying load description information can be improved.

[0023] In some embodiments, the cleaning procedure and / or the dehydration sub-parameters are determined based on the weight of the load and the saturated moisture content of the load.

[0024] In the above scheme, the accuracy of the determined cleaning parameters can be improved by the combined effect of multiple descriptive information.

[0025] In some embodiments, the default cleaning program includes a washing subprogram, a rinsing subprogram, and a spin-drying subprogram, each subprogram including one or more program parameters, and the controller is configured to:

[0026] If the load has a low moisture content, the first program is selected as the cleaning program; the first program removes the washing sub-program compared to the default cleaning program.

[0027] If the load is low and the moisture content is medium, then the second program is selected as the cleaning program; at least one of the program parameters of the second program, namely washing time, number of rinses, washing intensity, and rinsing intensity, is lower than the program parameters corresponding to the default cleaning program.

[0028] If the load is medium load and medium moisture content, then the third program is selected as the cleaning program; at least one of the program parameters of the washing power and rinsing power of the third program is lower than the program parameters corresponding to the default cleaning program.

[0029] If the load is high and the moisture content is medium, then select the default cleaning program as the cleaning program.

[0030] If the load is low and the moisture content is high, then the fourth program is selected as the cleaning program; at least one of the program parameters of the fourth program, such as the washing time and the number of rinsing cycles, is lower than the program parameters corresponding to the default cleaning program.

[0031] If the load is medium or high and has a high moisture content, then the fifth program is selected as the cleaning program; the fifth program also includes a soaking sub-program, and at least one of the program parameters of the fifth program, namely washing time, number of rinses, washing intensity, and rinsing intensity, is higher than the program parameters corresponding to the default cleaning program.

[0032] The above solution improves washing efficiency by involving multiple different washing programs and adaptively matching the washing program according to the washing load and moisture content.

[0033] In some embodiments, the dehydration sub-parameter is used to indicate the rotation of the cylinder during the dehydration stage. The dehydration sub-parameter includes the rotational speed of the cylinder in the first, second, third, and fourth stages, with each stage corresponding to a different rotational speed. The rotational speed increases sequentially from the first to the fourth stage. The controller is configured to:

[0034] If the load has a low or medium moisture content, then select the first dehydration sub-parameter;

[0035] If the load has a high moisture content, then select the second dehydration sub-parameter;

[0036] Wherein, the acceleration of the first dehydration sub-parameter from the second stage to the third stage, and the acceleration of the third stage to the fourth stage, are less than the second dehydration sub-parameter;

[0037] The duration of the first dehydration sub-parameter in the second and third stages is less than that of the second dehydration sub-parameter;

[0038] The rotational speeds of the first and second dehydration sub-parameters at different stages are positively correlated with the weight of the load.

[0039] In the above scheme, the dehydration curve is adaptively matched according to the load water absorption, thereby improving the safety of dehydration.

[0040] In some embodiments, the cleaning water level is determined based on the saturated water content of the load and whether the load is prone to floating.

[0041] In some embodiments, the default cleaning water level includes: a default washing water level, a default rinsing water level, and a default balancing water flow water level;

[0042] The controller is configured to:

[0043] If the load is a floating load or a non-floating load, and the saturated moisture content level of the load is low, then the first water level is selected as the cleaning water level; the first water level includes a first rinsing water level and a first balancing water flow level, the first rinsing water level is lower than the default rinsing water level, and the first balancing water flow level is lower than the default balancing water flow level.

[0044] If the load is a floating load and the saturated water content of the load is medium water content, then the second water level is selected as the washing water level; the second water level includes a second washing water level, a second rinsing water level, and a second balancing water flow water level, wherein the second balancing water flow water level is lower than the default balancing water flow water level;

[0045] If the load is a non-floating load and the saturated water content of the load is medium water content, then the third water level is selected as the washing water level; the third water level includes the third washing water level, the third rinsing water level and the third balancing water flow water level, and the third rinsing water level is lower than the default balancing water flow water level;

[0046] If the load is a floating load and the saturated water content of the load is high, then the fourth water level is selected as the washing water level; the fourth water level includes the fourth washing water level, the fourth rinsing water level and the fourth balancing water flow water level, the fourth washing water level is higher than the default washing water level, the fourth rinsing water level is higher than the default rinsing water level, and the fourth balancing water flow water level is lower than the fourth washing water level or the fourth rinsing water level;

[0047] If the load is a non-floating load and the saturated water content of the load is high, then the fifth water level is selected as the washing water level; the fifth water level includes the fifth washing water level, the fifth rinsing water level and the fifth balancing water flow level, the fifth washing water level is higher than the default washing water level, the fifth rinsing water level is higher than the default rinsing water level, and the fifth balancing water flow level is equal to the fourth washing water level or the fourth rinsing water level.

[0048] In some embodiments, the fourth rinsing water level is higher than the fourth washing rinsing water level, and the fifth rinsing water level is higher than the fifth washing rinsing water level.

[0049] In the above technical solution, the water level height of the balanced water flow before dehydration is adaptively matched according to whether it floats, thereby reducing the load eccentricity before dehydration and improving the dehydration success rate.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0082] Top-loading washing machines are still widely used by the public due to their simple and convenient operation.

[0083] To make it easier to understand, let's first introduce the washing programs of a top-loading washing machine:

[0084] refer to Figure 1 A top-loading washing machine, after starting the washing cycle, includes a preparation stage, a main wash stage (also known as a washing stage), a rinsing stage 1, a rinsing stage 2, and a final spin stage (spin-drying stage).

[0085] During the preparation stage, the washing machine performs fuzzy weighing to determine the weight of the load to be washed and, based on that weight, determines the amount of washing water and detergent to be added. The principle of fuzzy weighing is based on calculations using a specific frequency sine wave generated by the motor's back electromotive force (EMF). The motor's start-up and stop times are set. When the motor starts, it first generates magnetism to allow it to rotate normally. When the motor stops, it is allowed to run due to inertia, generating back EMF through magnetism. The faster the motor stops, the shorter the duration of the generated back EMF, and the fewer the corresponding sine waves. Since the clothes are in direct contact with the pulsator, which is connected to the motor shaft, the heavier the clothes, the greater the resistance to the pulsator's movement, the faster the motor stops, the shorter the duration of the generated back EMF, and the fewer the sine waves. Therefore, the weight of the clothes in the drum can be identified and measured based on the correspondence between the weight of the clothes and the back EMF.

[0086] After the preparation stage, the washing machine enters the main wash stage to clean the load. During the main wash, a water flow balancing process is performed to reduce noise. Water flow balancing refers to adjusting the water flow during operation to maintain internal balance within the washing machine, reducing vibration and noise. When the washing machine is spinning at high speed, especially during the spin-drying stage, clothes may concentrate on one side of the drum, causing imbalance. This imbalance can cause machine vibration, affecting washing performance and the machine's lifespan.

[0087] After the main wash cycle, the washing machine will sequentially enter the rinsing cycle 1 and rinsing cycle 2 for further cleaning. At the beginning and end of rinsing cycle 1 and rinsing cycle 2, spin-drying and water flow balancing processes will occur. After rinsing cycle 1 and rinsing cycle 2, the final spin-drying stage will complete the washing task.

[0088] Currently, most users either use the default program (also known as the standard program) or select a program they prefer when using a top-loading washing machine. However, these methods may present several problems:

[0089] 1. The washing program is not compatible with the clothes to be washed. For example, larger items such as four-piece bedding sets have a longer single-use cycle than everyday clothes. Therefore, users have higher requirements for the cleanliness of larger items and need to wash them for a longer time. Lighter clothes such as summer clothes are washed more frequently due to sweating and other reasons, and only require simple rubbing.

[0090] 2. Inappropriate water level. For example, some appliances use fuzzy weighing to automatically adjust the water level based on the weight of the laundry. However, simply selecting the water level based on the load weight is not the most suitable solution. Large loads may be lighter in weight but larger in size. The water level determined solely by weight may not completely submerge the large load, resulting in greater resistance for the unsubmerged parts during washing as the pulsator vibrates. This leads to greater eccentricity during washing and can cause problems with proper spin-drying.

[0091] 3. Incompatible dehydration curves. For example, when dehydrating a load with stronger water absorption, the saturated water content is higher due to the large amount of water absorbed, requiring a longer drainage time to reduce the water content of the load. At the same time, because the instantaneous water output rate during dehydration is higher, using the dehydration curve of a standard load can easily cause dehydration problems with water remaining, resulting in excessively high dehydration power and loud dehydration noise.

[0092] All of the above issues will make users feel that top-loading washing machines have poor washing performance, resulting in low user satisfaction.

[0093] In view of this, the present application provides a pulsator washing machine and its control method. During the washing process, the load is weighed multiple times, and the weight and water absorption of the load are identified based on the weighing results. Based on the identification results, a washing program, water level height dehydration curve, etc. suitable for the load are intelligently allocated, which can achieve more efficient and safer washing for different loads, thereby improving the user experience.

[0094] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0095] For ease of description, unless otherwise specified, the directions of up, down, left, right, front, and back in this application are based on the state of the pulsator washing machine in use, with the direction facing the user being the front direction and the direction away from the user being the back direction; the vertical direction is up and down, and the horizontal direction is left and right. In the accompanying drawings, the left and right direction is shown using the X-axis, the front and back direction is shown using the Y-axis, and the vertical direction is shown using the Z-axis.

[0096] Combination Figure 2 and Figure 3 The pulsator washing machine of this application embodiment includes a cabinet 10. The cabinet 10 serves as the main carrier of the pulsator washing machine, which is used to install internal washing components, water inlet and drainage components, etc., and also to support the pulsator washing machine on the ground.

[0097] To improve the utilization of the space occupied by the pulsator washing machine, the cabinet 10 is usually cubic in shape, for example, Figure 1 The cuboid shown in the image.

[0098] The top of the casing 10 is provided with a frame 30, which provides space for the installation of the control components of the pulsator washing machine. The frame 30 forms a loading port 31 through which the laundry enters the inner drum for washing.

[0099] The pulsator washing machine also includes a door cover 20, which is rotatably mounted on the frame 30 to open or close the loading port 31.

[0100] In some embodiments, the rear end of the cover 20 is rotatably connected to the frame 30, thereby allowing the cover 20 to rotate upward to open the dispensing port 31. The cover 20 can rotate downward to close the dispensing port 31.

[0101] In some embodiments, the pulsator washing machine further includes a drum assembly (also referred to as a drum body) installed within the housing 10. The drum assembly extends axially along the height direction of the pulsator washing machine to form a pulsator-type washing machine.

[0102] The drum assembly includes an outer drum, which is installed inside the housing 10. The outer drum is constructed to contain washing water, that is, the internal space of the outer drum is used to hold washing liquids such as water, detergent, fabric softener, etc.

[0103] The drum assembly also includes an inner drum, which is rotatably installed inside the outer drum. The inner drum has water passages on its peripheral wall, connecting the outer and inner drums, allowing washing water from the outer drum to enter the inner drum. Clothes and other laundry are placed in the inner drum, which rotates relative to the outer drum to clean the laundry.

[0104] In some embodiments, the housing 10 is provided with a drive device, such as a drive motor, and the output end of the drive device is connected to the inner drum via a transmission connection. When the drive device is started, it drives the inner drum to rotate relative to the outer drum, thereby realizing the washing or dehydration function of the laundry inside the inner drum.

[0105] In some embodiments, the inner cylinder and the outer cylinder are arranged coaxially, and the openings of both the inner cylinder and the outer cylinder face the inlet 31.

[0106] Continue to refer to Figure 2 In some embodiments, the pulsator washing machine also includes a spraying mechanism 500, which may be disposed on the peripheral sidewall of the inlet 31 to spray water toward the inner drum.

[0107] The water inlet of the spray mechanism 500 can be connected to an external water source to supply water for spraying. In some embodiments, the pulsator washing machine includes a first water inlet mechanism 400, one of the ports of which is connected to the spray mechanism 500 to supply water for spraying.

[0108] The spraying end of the spraying mechanism 500 can be exposed on the peripheral wall of the inlet 31 to spray into the inner cylinder. In some embodiments, the frame 30 is provided with a first mounting port 32 and a second mounting port 33, so that the spraying end of the spraying mechanism 500 is fixedly exposed on the peripheral wall of the inlet 31 through the first mounting port 32 and the second mounting port 33.

[0109] In some embodiments, combined with Figure 3 The spraying mechanism 500 includes a spray pipe 510, one end of which is connected to one of the ports of the first water inlet mechanism 400 to guide the water from the first water inlet mechanism 400 to the spraying end.

[0110] The spray mechanism 500 also includes a spray head 520, which is fixed to one end of the spray pipe 510 away from the first water inlet mechanism 400, and at least a portion of the spray head 520 is exposed through the second mounting port 33 to the inlet port 31. Thus, water from the first water inlet mechanism 400 is sprayed from the spray head 520 towards the inner drum via the spray pipe 510. Compared to simple water inlet, the spray area is larger, which can expand the wetting range of the external water source on the clothes, thereby quickly wetting the clothes and improving the washing efficiency.

[0111] In some embodiments, the first water inlet mechanism 400 is provided with a water inlet valve, which controls whether an external water source enters the spray pipe 510, that is, controls whether the spray mechanism 500 is started.

[0112] For example, before the washing program starts, external water is sprayed onto the clothes in the inner drum through the spray mechanism 500 to pre-wash the clothes and quickly wet them. When the detergent and water mixture enters the inner drum, the detergent spreads quickly inside the wet clothes, improving the mixing effect of the detergent and thus improving the washing effect.

[0113] In some embodiments, the pulsator washing machine further includes a drainage mechanism, which may be disposed on the peripheral side wall of the casing 10 and connected to the drum body for discharging washing water inside the drum body during the washing process. For example, the drainage mechanism is provided with a drain valve, which controls whether to discharge washing water from the drum body.

[0114] The structure of the pulsator washing machine provided in the embodiments of this application has been described above. Based on the above-described pulsator washing machine, the control method of the pulsator washing machine provided in the embodiments of this application will be described below, taking the controller of the pulsator washing machine as the execution subject. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0115] Figure 4 A flowchart illustrating a control method for a pulsator washing machine (hereinafter referred to as the washing machine) provided in an embodiment of this application is shown below. Figure 4 As shown, it includes the following steps:

[0116] S401. Execute the first weighing task to obtain the first weight of the load in the cylinder; the first weighing task is configured to weigh the load.

[0117] In some embodiments, when the controller receives a start signal, it can perform a first weighing task to weigh the load in the drum and obtain a first weight of the load. The first weighing task can be performed using fuzzy weighing or other methods. For example, the washing machine is equipped with a weight sensor, and the first weight of the load is determined based on the weight sensor. Specific implementation methods for performing the first weighing task can refer to existing technologies, and will not be elaborated upon in this application.

[0118] It should be understood that the first weighing task is the first task of washing the load. At this time, the load put into the washing machine is usually in a dry state. Therefore, performing the first weighing task can also be called weighing the load while it is dry.

[0119] S402. Perform a second weighing task to obtain the second weight of the load in the cylinder; the second weighing task is configured to control the water inlet valve to open for a first preset time to weigh the load.

[0120] In some embodiments, after completing the first weighing task, the controller can open the water inlet valve to inject washing water into the drum, allowing the load to be fully soaked. For example, the controller can determine a set water level for the required washing water based on the first weight and open the water inlet valve. After the injected washing water reaches the set water level, the controller closes the water inlet valve. After waiting for a preset time (e.g., 1 minute) to allow the load to fully soak and absorb water, the controller opens the water inlet valve again to replenish water. After the water level reaches the set water level, the controller closes the water inlet valve. Then, the load is weighed with water to determine a second weight. The second weight of the load can also be determined using fuzzy weighing or a weight sensor weighing method, etc.

[0121] S403. Perform a third weighing task to obtain the third weight of the load in the cylinder; the third weighing task is configured to control the drain valve to open for a second preset time to weigh the load.

[0122] In some embodiments, after completing the second task, the controller can open the drain valve for a preset time to drain the washing water injected during the second weighing task, and then weigh the load to obtain the third weight of the load. For example, after opening the drain valve to drain the washing water to the reset water level, drainage continues for 30 seconds to completely drain the injected washing water. During the third weighing of the load, the load is in a wet state; therefore, performing the third weighing task can also be referred to as weighing the load with a wet cloth. The third weight of the load can also be determined using fuzzy weighing or weight sensor weighing, etc.

[0123] S404. Determine the description information of the load based on the first weight, the second weight, and the third weight; the description information includes the weight of the load, the saturated water content, and whether it is easy to float.

[0124] When the controller obtains the first weight, the second weight, and the third weight, it can determine the description information of the load based on the relationship between the first weight, the second weight, and the third weight and the relationship between the preset weight threshold.

[0125] In some embodiments, if the first weight is less than a first preset weight, the load weight is determined to be a low load; if the first weight is greater than or equal to the first preset weight and less than or equal to a second preset weight, the load weight is determined to be a medium load; if the first weight is greater than the second preset weight, the load weight is determined to be a high load.

[0126] For example, the first weight is m1. If m1 < M1 (first preset weight), the load is determined to be light and can be marked as low load (or small load). If M1 ≤ m1 ≤ M2 (second preset weight), the load weight is determined to be medium and can be marked as medium load. If M1 ≤ m1, the load is determined to be heavy and can be marked as high load (or large load). It should be understood that the values ​​of M1 and M2 can be set according to actual experience, and this application embodiment does not limit them.

[0127] In some embodiments, if the second weight is less than the first weight, the load is determined to be a buoyant load; if the second weight is greater than or equal to the first weight, the load is determined to be a non-buoyant load.

[0128] For example, since the second weight (m2) is obtained by weighing the load after it is immersed in water, if m2 < m1, it means that the weight of the load immersed in water is less than the dry weight. The load may float on the water surface due to its low density. Since the buoyancy of the water causes the weight immersed in water to be less than the dry weight, the load is marked as a load that is easy to float. Conversely, if m1 ≤ m2, the load is marked as a load that is not easy to float.

[0129] In some embodiments, if the third weight is less than M times the first weight, the saturated moisture content of the load is determined to be low moisture content; if the third weight is greater than or equal to M times the first weight, and the third weight is less than or equal to N times the first weight, the saturated moisture content of the load is determined to be medium moisture content; if the third weight is greater than N times the first weight, the saturated moisture content of the load is determined to be high moisture content; where M is greater than N, and both M and N are greater than zero.

[0130] For example, the following table shows the water absorption capacity of some common loads:

[0131]

[0132] As shown in the table above, the higher the saturated moisture content of the load (the higher the water absorption capacity), the higher the ratio between the third weight (wet weight m3) and the first weight (dry weight m1).

[0133] If m3 < M*m1, it can be determined that the difference between the dry weight and wet weight of the load is small, and the load can be marked as a load with low saturated moisture content (low moisture content). If m3 > N*m1, it can be determined that the difference between the dry weight and wet weight of the load is large, and the load can be marked as a load with high saturated moisture content (high moisture content). In other cases (M*m1≤m3≤N*m1), the load is marked as a load with moderate saturated moisture content (medium moisture content), where M is less than N.

[0134] For example, if m3 < 1.05 * m1, the load can be marked as a load with low saturated moisture content; if m3 > 5 * m1, the load can be marked as a load with high saturated moisture content; and in other cases, it can be marked as a load with moderate saturated moisture content. It should be understood that the values ​​of M and N can be set according to actual needs, for example, M = 1.1 and N = 6, etc., and this application embodiment does not limit this.

[0135] S405. Based on the description information, determine the cleaning parameters for cleaning the load, and clean the load based on the cleaning parameters.

[0136] In some embodiments, when the controller obtains the description information of the load, it can generate or determine the cleaning parameters for the load based on the description information, so that the cleaning parameters for the load match the load, thereby enabling more efficient and safer washing of the load when cleaning it based on the cleaning parameters, thus improving the user experience.

[0137] In some embodiments, the washing parameters may include parameters throughout the washing process. For example, the washing parameters may include at least one of the following: washing program, washing water level, and dehydration sub-parameters. The dehydration sub-parameters may also be referred to as the dehydration curve during the dehydration process.

[0138] The cleaning water level may include at least one of the following: washing water level, rinsing water level, and balancing water flow level.

[0139] In some embodiments, when the controller obtains the description information of the load, it can process the description information using a preset parameter generation algorithm or model to generate cleaning parameters for the load. Alternatively, it can query a preset cleaning parameter library based on the description information to find cleaning parameters that match the description information. This application embodiment does not limit the method of determining the cleaning parameters.

[0140] The washing machine control method provided in this application determines the accurate description information of the load by weighing it three times before washing it, and generates cleaning parameters for the load based on the description information. This makes the cleaning parameters of the load match the load, reducing the probability of inadequate cleaning of the load due to mismatched cleaning programs or water levels, and achieving more efficient and safer washing of the load, thereby improving the user experience.

[0141] Based on the above embodiments, the process of determining the cleaning parameters for cleaning the load based on the described information will be further explained below.

[0142] Figure 5 A flowchart illustrating another control method for a washing machine provided in this application embodiment is shown below. Figure 5 As shown, it includes:

[0143] S501. Determine the cleaning procedure and / or the dehydration sub-parameters based on the weight of the load and the saturated moisture content of the load.

[0144] In some embodiments, the washing machine has a built-in washing program library, which includes multiple washing programs and corresponding usage conditions. When the controller determines the weight of the load and the saturated moisture content of the load, it can query the corresponding washing program from the washing program library.

[0145] For example, Figure 6 This is a schematic diagram of a laundry program library provided in an embodiment of this application. The laundry program library includes a first program, a second program, a third program, a fourth program, a fifth program, and a standard program (default program), and their corresponding usage conditions. The different programs have different program parameters during the washing, rinsing, and spin-drying processes. For example, program parameters may include washing time, number of rinsing cycles, washing intensity, and rinsing intensity.

[0146] like Figure 6 As shown, if the controller determines that the load has a low moisture content, regardless of the weight of the load, the first program is selected as the cleaning program.

[0147] When a washing machine performs a wash cycle, it can include a washing stage, a rinsing stage, and a spin-drying stage. Correspondingly, the default (standard) washing program of the washing machine can include a washing sub-program used in the washing stage, a rinsing sub-program used in the rinsing stage, and a spin-drying sub-program used in the spin-drying stage.

[0148] In this program, the washing sub-program is removed compared to the default washing program. Since the load has a low moisture content, the difference between the wet weight and dry weight of the load is very small, confirming that the load itself is a wet load. Therefore, the washing machine selects to use the first program (also known as the rinsing program) to wash the load.

[0149] In some embodiments, if the load is low and the moisture content is medium, a second program is selected as the washing program. In this second program, at least one of the following parameters—washing time, number of rinses, washing intensity, and rinsing intensity—is lower than the parameter corresponding to the default washing program. For example, the second program can be a quick wash or a fast wash program.

[0150] In some embodiments, if the load is medium load and medium moisture content, a third program is selected as the washing program; wherein, at least one of the program parameters of the washing intensity and rinsing intensity of the third program is lower than the program parameters corresponding to the default washing program. For example, the third program can be a gentle program.

[0151] In some embodiments, if the load is high and the moisture content is medium, the default cleaning program is selected as the cleaning program.

[0152] In some embodiments, if the load is low and the moisture content is high, a fourth program is selected as the cleaning program; at least one of the program parameters of the fourth program, such as washing time and rinsing times, is lower than the program parameters corresponding to the default cleaning program. For example, the fourth program can be a bath towel program.

[0153] In some embodiments, if the load is a medium or high load and has a high moisture content, then the fifth program is selected as the cleaning program; the fifth program further includes a soaking sub-program, and at least one of the program parameters of the fifth program—washing time, number of rinses, washing intensity, and rinsing intensity—is higher than the program parameters corresponding to the default cleaning program. For example, the fifth program can be a large item / intensive wash / home textiles / mite removal program.

[0154] In some embodiments, dehydration sub-parameters (also known as dehydration curves) during the dehydration process are used to indicate the rotation of the cylinder during the dehydration stage.

[0155] The spin-drying process of a top-loading washing machine includes two resonance zones: one is the pendulum mode when the suspension rod twists horizontally with the tub during startup (approximately 60-90 revolutions per minute), and the other is the elastic mode caused by the up-and-down vibration of the suspension rod spring (approximately 180-220 revolutions per minute).

[0156] During dehydration, the drum vibrates under forced vibration. The amplitude of the resonance zone is closely related to the damping force, and the rotational speed and position of the resonance zone are related to the spring constant and the mass of the inner and outer drum assemblies. Under the condition that the machine's structural components, such as the damping force, the spring constant of the suspension rod, and the mass of the drum, are designed reasonably, the dehydration curve should be adjusted to ensure that the drum quickly passes through the resonance zone when there is a small eccentricity. For large eccentricities, the machine needs to be stopped by the safety switch before passing through the resonance zone to prevent excessive shaking that could cause the machine to collide with the housing and result in dangerous situations such as overall machine displacement.

[0157] In some embodiments, if the load has a low or medium moisture content, a first dehydration sub-parameter is selected; if the load has a high moisture content, a second dehydration sub-parameter is selected. The dehydration sub-parameter includes the rotational speed of the cylinder in the first, second, third, and fourth stages, with each stage corresponding to a different rotational speed, and the rotational speed increasing sequentially from the first to the fourth stage.

[0158] like Figure 7 As shown, if the load has a low or medium moisture content, the first dehydration sub-parameter (curve A) is selected as the dehydration parameter; if the load has a high moisture content, the second dehydration sub-parameter (curve B) is selected as the dehydration parameter. The duration of the first dehydration sub-parameter in the second and third stages is shorter than that of the second dehydration sub-parameter. The rotational speeds of the first and second dehydration sub-parameters at different stages are positively correlated with the weight of the load. For example, for curve B, the heavier the load at different stages, the higher the corresponding rotational speed. The specific rotational speed can be determined from a preset rotational speed-weight table.

[0159] Using different dehydration curves for different moisture contents, coupled with different rotation speeds corresponding to different loads, can reduce the dehydration efficiency under low moisture content loads, while also solving the problem of excessive instantaneous water output during dehydration under high water absorption loads. Dehydration under water mainly involves problems such as high dehydration noise, high power consumption due to excessive dehydration power, and water entering the air chamber of the water level sensor connected to the outer tub, leading to malfunction in the water level detection frequency.

[0160] like Figure 7As shown, for loads with low or medium moisture content, curve A is used. After passing through the resonance zone, the maximum speed V4 is quickly reached and maintained, reducing the moisture content of the load. For loads with high moisture content, curve B is used. After passing through the resonance zone, the maintenance time of the low speed V2 is extended, allowing more time to expel the water. Simultaneously, because loads with high moisture content are more hydrophilic, water molecules are less likely to detach. Higher acceleration is required to throw them out through centrifugal force, ensuring that most of the water in the load is expelled before reaching the maximum speed v4. Therefore, the acceleration a2 when v2 increases to v3 is greater than a1; and the acceleration a4 when v3 increases to v4 is greater than a3.

[0161] S502. Determine the cleaning water level based on the saturated water content of the load and whether the load is prone to floating.

[0162] In some embodiments, the washing water level may include the water level during washing, the water level during balancing flow, and the water level height during rinsing.

[0163] Using an appropriate water level during washing enhances stain removal and increases the washing efficiency. A suitable water level during rinsing increases the rinsing rate. A balanced water flow is used before spin-drying to disperse any imbalances caused by washing, reducing the imbalance within the drum, increasing the spin-drying success rate, and decreasing spin-drying noise to improve the user experience.

[0164] In some embodiments, if the load is a floatable or non-floating load, and the load's saturated moisture content is low, then a first water level is selected as the washing water level. Since the load's saturated moisture content is low, the washing process does not include a washing phase. Therefore, the first water level includes a first rinsing water level and a first balancing water flow level. The first rinsing water level is lower than the default rinsing water level, and the first balancing water flow level is lower than the default balancing water flow level. The default washing water level can be determined by weighing the load at the start of washing, the default rinsing water level can be determined by weighing the load at the start of rinsing, and the default balancing water flow level can be determined by weighing the load at the start of balancing water flow.

[0165] In some embodiments, if the load is a floatable load and the saturated water content of the load is medium, then a second water level is selected as the washing water level; the second water level includes a second washing water level, a second rinsing water level, and a second balancing water flow level, wherein the second balancing water flow level is lower than the default balancing water flow level. The remaining water levels are the same as the corresponding default water levels.

[0166] In some embodiments, if the load is a non-floating load and the saturated water content of the load is medium, then a third water level is selected as the washing water level; the third water level includes a third washing water level, a third rinsing water level, and a third balancing water flow level, wherein the third rinsing water level is lower than the default balancing water flow level. The remaining water levels are the same as the corresponding default water levels.

[0167] In some embodiments, if the load is a floating load and the saturated water content of the load is high, then a fourth water level is selected as the washing water level; the fourth water level includes a fourth washing water level, a fourth rinsing water level and a fourth balancing water flow level, wherein the fourth washing water level is higher than the default washing water level, the fourth rinsing water level is higher than the default rinsing water level, and the fourth balancing water flow level is lower than the fourth washing water level or the fourth rinsing water level.

[0168] In some embodiments, if the load is a non-floating load and the saturated water content of the load is high, then the fifth water level is selected as the washing water level; the fifth water level includes a fifth washing water level, a fifth rinsing water level and a fifth balancing water flow level, the fifth washing water level is higher than the default washing water level, the fifth rinsing water level is higher than the default rinsing water level, and the fifth balancing water flow level is equal to the fourth washing water level or the fourth rinsing water level.

[0169] In some embodiments, the fourth rinsing water level is higher than the fourth washing water level, and the fifth rinsing water level is higher than the fifth washing water level. For loads with high moisture content, setting a higher rinsing water level can further improve the rinsing effect and reduce the problem of low rinsing water levels affecting the rinsing effect due to excessively high load moisture content.

[0170] For example, such as Figure 8 As shown, the washing machine has multiple water level settings; the higher the setting, the higher the corresponding water level.

[0171] If the load is either easily floating or not easily floating, and the load's saturated moisture content is low, the rinsing water level and the balancing water flow level are one level lower than the standard water level determined by fuzzy weighing of the load at the start of rinsing. If the load is easily floating, and the load's saturated moisture content is medium, the washing water level and rinsing water level are their respective default water level settings based on the load's initial weighing, and the balancing water flow level is one level lower than the default level determined by fuzzy weighing before the start. If the load is not easily floating, and the load's saturated moisture content is medium, the washing water level and the balancing water flow level can be their respective default water level settings based on the load's initial weighing, and the rinsing water level can be one level higher than the level obtained by fuzzy weighing of the load before the start of rinsing. If the load is a easily floating load and its saturated moisture content is high, the washing water level is one level higher than the default water level based on fuzzy weighing, the rinsing water level is two levels higher than the default water level based on fuzzy weighing, and the balancing water flow level is consistent with the washing water level level. If the load is a not easily floating load and its saturated moisture content is high, the washing water level is one level higher than the default water level based on fuzzy weighing, the rinsing water level is two levels higher than the default water level based on fuzzy weighing, and the balancing water flow level is consistent with the washing or rinsing water level level.

[0172] In summary, the washing machine control method provided in this application embodiment identifies the load comprehensively through three weighings, adaptively matches the washing program based on the identification results to improve washing efficiency (washing ratio), adaptively matches the water level height of the balancing water flow before spin-drying based on whether the load is floating to reduce load eccentricity before spin-drying and improve spin-drying success rate, and adaptively matches the spin-drying curve based on the load moisture content to improve spin-drying safety. This solves the problems of high spin-drying power and high noise caused by spin-drying with water due to mismatched spin-drying curves, thereby enabling more efficient washing and safer spin-drying of clothes of different materials.

[0173] The control method for the washing machine provided in this application is illustrated below with a specific example.

[0174] refer to Figure 9 When the washing machine controller receives the start signal, it enters the preparation stage, performs a dry cloth fuzzy weighing of the load to obtain the first weight of the load, then opens the water inlet valve to allow water to enter, performs a fuzzy weighing of the load after water entry to obtain the second weight of the load, then opens the drain valve to drain the water, and performs a fuzzy weighing after settling to obtain the third weight of the load.

[0175] Based on the obtained first, second, and third weights, descriptive information (e.g., the weight of the load, saturated water content, and whether it is easily floatable) is determined. Based on the determined load descriptive information, the load cleaning process is performed by allocating water level and cleaning procedures, and selecting a dehydration curve, thus completing the preparation phase.

[0176] The main wash stage then begins, where the load is cleaned based on a predetermined water level and cleaning procedure. After balancing the water flow, it enters the rinsing stage 1. In rinsing stage 1, the load is first dehydrated based on a selected dehydration curve, then rinsed at a predetermined rinsing water level, and finally balanced with a balancing water flow level. This completes rinsing stage 1, and the load proceeds to rinsing stage 2. The process of rinsing stage 2 is similar to that of rinsing stage 1 and will not be described in detail here.

[0177] After the second rinsing stage, the load is dehydrated using the selected dehydration curve in the final dehydration stage. After dehydration, the cleaning of the load is completed.
