Description

Technical Field

[0001] This invention relates to the field of washing machines, and more particularly to a method, system, washing machine, and storage medium for washing clothes. Background Technology

[0002] Washing machines, a widely used household appliance, have freed people from the hassle of washing clothes, bringing them great convenience. They efficiently remove stains and impurities from clothing through a combination of mechanical and chemical actions. Washing machines are simple and convenient to operate; simply pressing a button completes the entire process of washing, rinsing, and spinning, making them ideal for fast-paced lifestyles.

[0003] Current washing machines use soaked water to wash clothes. If there is a lot of dust or lint in the washing water, it will adhere to the clothes during the washing process, affecting the washing effect and resulting in a poor user experience. Summary of the Invention

[0004] The purpose of this invention is to provide a method, system, washing machine, and storage medium for washing clothes, which can effectively clean dirt that floats on the water or sinks to the bottom during the soaking process, ensure the washing effect of the clothes, eliminate the need to drain the soaking water and refill a large amount of water, thus avoiding water waste and improving the user experience.

[0005] To achieve the above objectives, the following technical solution is provided:

[0006] Firstly, this invention provides a method for washing clothes, comprising: detecting the turbidity of the washing water in the drum to obtain turbidity values ​​at different time points; comparing the turbidity values ​​at different time points to determine whether there are dirt or grime in the washing water and the type of dirt; and performing different cleaning operations according to the different types of dirt. If the dirt in the washing water is light filaments, it can be cleaned and discharged by overflowing water. Simultaneous water intake and overflow can prevent secondary contamination of clothes by light filaments. If the dirt in the washing water is heavy dust, it can be cleaned and discharged by draining water. New water is then added to the remaining clean water for subsequent washing operations, saving water consumption required for cleaning dirt. This effectively cleans dirt that floats on the water or sinks during soaking, ensuring the washing effect of the clothes. It eliminates the need to drain the soaking water and refill with large amounts of water, thus avoiding water waste, improving the user experience, and enhancing the product competitiveness of the washing machine.

[0007] As an optional solution to the clothing washing method provided by the present invention, if there are dirt in the washing water in the drum and the type of dirt is floating dirt, then an overflow cleaning operation is performed; if there are dirt in the washing water in the drum and the type of dirt is sediment, then a drain cleaning operation is performed; if there are no dirt in the washing water in the drum, then a washing operation is performed.

[0008] As an optional embodiment of the clothing washing method provided by the present invention, the clothing washing method includes the following steps:

[0009] S101. Water is introduced into the drum to set the water level, and the current turbidity of the washing water in the drum is detected to obtain the first turbidity value m0;

[0010] S102. After the first preset time for the washing water in the mixing drum, the current turbidity of the washing water in the drum is detected to obtain the second turbidity value m1.

[0011] S103. After the washing water in the drum has been left to stand for a second preset time, the current turbidity of the washing water in the drum is detected to obtain the third turbidity value m2.

[0012] S104. Determine whether the inequality m1-m0≥n1 is true, where n1 is the first preset turbidity difference. If yes, proceed to step S105.

[0013] S105. Determine whether the inequality |m2-m1|≥n2 is true, where n2 is the second preset turbidity difference. If yes, drain water to a preset drain level lower than the current water level in the drum, refill water to the set water level in the drum, add detergent, and continue the washing program. If no, refill water to a preset overflow level higher than the current water level in the drum, and after a third preset time for both water inlet and overflow, drain water to a preset drain level lower than the current water level in the drum, refill water to the set water level in the drum, add detergent, and continue the washing program.

[0014] By detecting the turbidity values ​​(m0, m1, and m2) of the washing water at three points—before washing, after agitation, and after settling—and comparing whether the inequalities m1-m0≥n1 and |m2-m1|≥n2 hold true, the type of dirt present in the washing water inside the drum can be determined. If the dirt in the washing water is light lint or similar debris, it can be cleaned and drained by overflowing water. Simultaneous water intake and overflow prevents secondary contamination of clothes by these light lint or similar debris. If the dirt in the washing water is heavy dust or similar debris, it can be cleaned and drained by draining water. New water is then added to the remaining clean water for subsequent washing operations, saving water needed for cleaning dirt. This effectively removes dirt that floats on or sinks during soaking, ensuring the washing effect of the clothes. It eliminates the need to drain the soaking water and refill with large amounts of water, thus saving water resources, improving the user experience, and enhancing the product competitiveness of the washing machine.

[0015] As an optional solution to the clothing washing method provided by the present invention, in step S104, if it is determined that the inequality m1-m0≥n1 is not true, then it is further determined whether the inequality m2-m0≥n3 is true, where n3 is a third preset turbidity difference value. If yes, then the water is drained to a preset drainage level lower than the current water level in the drum, water is refilled to the set water level in the drum, detergent is added, and the washing program continues; if no, then detergent is added, and the washing program continues. When the stirring process fails to separate dirt from the clothes and there is no obvious increase in turbidity, the turbidity after settling can be compared with the turbidity before washing to avoid affecting the washing effect.

[0016] As an optional solution to the clothing washing method provided by the present invention, before step S101, it is determined whether the clothing is light-colored. If so, water is added and a preset weight of detergent is added, and then the process proceeds to step S101; otherwise, the process proceeds directly to step S101. When the clothing is light-colored, a small amount of detergent can be added first for washing, stirring, and letting it stand. The remaining amount of detergent is added during the subsequent washing process to ensure the washing effect of light-colored clothing.

[0017] As an optional solution to the clothing washing method provided by the present invention, when the water level is increased to a preset overflow level higher than the current water level in the drum, the water inlet valve is opened to start water intake. Water intake continues until the preset overflow level is reached, and timing begins. Water intake and overflow occur simultaneously. When the timing reaches the third preset time, the water inlet valve is closed to stop water intake.

[0018] As an optional solution to the clothing washing method provided by the present invention, when the current water level in the drum reaches the preset overflow water level, water continues to be added, and the washing water in the drum flows out from the overflow outlet of the washing machine. The water flow is adjusted by controlling the rotation mode of the washing drum drive motor, controlling the washing drum drive motor to rotate in one direction or in two directions; and / or, controlling the washing drum drive motor to stop rotating.

[0019] Secondly, the present invention also provides a laundry washing system for implementing the washing machine pre-set washing method described above, comprising:

[0020] The turbidity detection module is used to detect the current turbidity of the washing water in the drum;

[0021] The water level detection module is used to detect the current water level in the drum.

[0022] The water inlet module is used to introduce water into the washing drum;

[0023] Drainage module, used to drain water out of the washing drum;

[0024] The timing module is used to calculate time;

[0025] The first judgment module is used to determine whether the inequality m1-m0≥n1 is true;

[0026] The second judgment module is used to determine whether the inequality |m2-m1|≥n2 is true;

[0027] If the first judgment module determines that the inequality m1-m0≥n1 is true, and the second judgment module determines that the inequality |m2-m1|≥n2 is true, then the control module drains water to a preset drainage level lower than the current water level in the drum, and then refills water to the set water level in the drum through the water inlet module, adds detergent, and continues to execute the washing program through the control module. If the first judgment module determines that the inequality m1-m0≥n1 is true, and the second judgment module determines that the inequality |m2-m1|≥n2 is not true, then the water inlet module adds water to a preset overflow level higher than the current water level in the drum. After the water inlet and overflow occur simultaneously for a third preset time, the drain module drains water to a preset drainage level lower than the current water level in the drum, and then refills water to the set water level in the drum through the water inlet module, adds detergent, and continues to execute the washing program through the control module.

[0028] Thirdly, the present invention also provides a washing machine, the washing machine including a memory, a processor and a computer program stored in the memory and running on the processor, wherein the processor executes the program to implement the clothing washing method as described above.

[0029] Fourthly, the present invention also provides a computer-readable storage medium having a computer program stored thereon that, when executed by a processor, implements the clothing washing method described above.

[0030] Compared with existing technologies, the laundry washing method, system, washing machine, and storage medium provided by this invention detect the turbidity of the washing water in the drum at different time points. By comparing the turbidity values ​​at different time points, it is determined whether there are dirt or debris in the washing water and the type of dirt. Different cleaning operations are performed according to the type of dirt. For example, if there is dirt or debris in the washing water and the type of dirt is floating, an overflow cleaning operation is performed; if there is dirt or debris in the washing water and the type of dirt is sedimented, a drainage cleaning operation is performed; if there is no dirt or debris in the washing water, a washing operation is performed. If the dirt in the washing water is light and grime, it can be drained through overflow. Simultaneous water intake and overflow prevents secondary contamination of clothes by these light particles. If the dirt in the washing water is heavier and grime, it can be drained through drainage. New water can then be added on top of the remaining clean water for subsequent washing operations, saving water needed for cleaning. This effectively removes dirt that floats or sinks during soaking, ensuring optimal washing results. It eliminates the need to drain the soaking water and refill with large amounts of water, thus saving water resources, improving the user experience, and enhancing the washing machine's competitiveness.

[0034] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] The laundry washing method includes: detecting the turbidity of the wash water in the drum to obtain turbidity values ​​at different time points; comparing the turbidity values ​​at different time points to determine whether there are dirt or grime in the wash water and the type of dirt or grime; and performing different cleaning operations based on the type of dirt or grime. For example, if there is dirt or grime in the wash water and the type of dirt or grime is floating, an overflow cleaning operation is performed; if there is dirt or grime in the wash water and the type of dirt or grime is sedimented, a drain cleaning operation is performed; and if there is no dirt or grime in the wash water, a washing operation is performed. If the dirt in the washing water is light and grime like lint, it can be drained by overflowing. Simultaneous filling and overflowing prevents secondary contamination of clothes by these light particles. If the dirt is heavier and grime like dust, it can be drained by draining. New water can then be added on top of the remaining clean water for subsequent washing operations. This saves water needed for cleaning dirt and effectively removes dirt that floats or sinks during soaking, ensuring good washing results. It eliminates the need to drain the soaking water and refill with large amounts of water, thus saving water and improving the user experience and competitiveness of the washing machine.

[0037] Optionally, Figure 1 The flowchart of the clothing washing method provided in this embodiment is as follows: Figure 1 As shown, this garment washing method includes the following steps:

[0038] S101. Water is introduced into the drum to the set water level, and the current turbidity of the washing water in the drum is detected to obtain the first turbidity value m0. Water introduction can be controlled by the water inlet valve. Opening the water inlet valve adds water to the set water level in the drum, and then closing the water inlet valve allows the turbidity sensor to detect the current turbidity of the washing water in the drum. Whether water has been introduced to the set water level in the drum can be detected by the water level sensor. When the water level sensor detects that the current water level in the drum has reached the set water level, it sends a feedback signal to the washing machine controller.

[0039] S102. After the first preset time for washing water in the drum, the current turbidity of the washing water is detected to obtain a second turbidity value m1. The washing machine contains an agitator or agitator plate, which rotates and moves up and down rapidly under the drive of a motor, thereby causing water flow and friction and washing of the clothes. During the agitation process, dirt on the clothes separates from the clothes; lighter dirt floats on the surface, while heavier dirt sinks. The first preset time can be 30%-50% of the total soaking time.

[0040] S103. After the washing water in the drum has settled for a second preset time, the current turbidity of the washing water is measured to obtain a third turbidity value m2. After sufficient settling, lighter dirt will float on the surface, while heavier dirt will sink to the bottom, facilitating subsequent cleaning. The second preset time can be 30%-50% of the total soaking time.

[0041] S104. Determine if the inequality m1-m0≥n1 is true, where n1 is the first preset turbidity difference. If yes, proceed to step S105. If the inequality m1-m0≥n1 is true, it indicates that dirt adhering to the clothes during the stirring process has separated from the clothes and remains in the washing water. If it is not cleaned and drained, it will affect the subsequent washing effect. If the inequality m1-m0≥n1 is not true, it initially indicates that the washing water is relatively clean and does not contain much dirt, thus having a small impact on the washing effect.

[0042] S105. Determine whether the inequality |m2-m1|≥n2 is true, where n2 is the second preset turbidity difference. If yes, drain water to a preset drain level lower than the current water level in the drum, refill water to the set water level in the drum, add detergent, and continue the washing program. If no, refill water to a preset overflow level higher than the current water level in the drum, and after a third preset time for both water inlet and overflow, drain water to a preset drain level lower than the current water level in the drum, refill water to the set water level in the drum, add detergent, and continue the washing program.

[0043] By detecting the turbidity values ​​(m0, m1, and m2) of the washing water at three points—before washing, after agitation, and after settling—and comparing whether the inequalities m1-m0≥n1 and |m2-m1|≥n2 hold true, the type of dirt present in the washing water inside the drum can be determined. If the dirt in the washing water is light lint or similar debris, it can be cleaned and drained by overflowing water. Simultaneous water intake and overflow prevents secondary contamination of clothes by these light lint or similar debris. If the dirt in the washing water is heavy dust or similar debris, it can be cleaned and drained by draining water. New water is then added to the remaining clean water for subsequent washing operations, saving water needed for cleaning dirt. This effectively removes dirt that floats on or sinks during soaking, ensuring the washing effect of the clothes. It eliminates the need to drain the soaking water and refill with large amounts of water, thus saving water resources, improving the user experience, and enhancing the product competitiveness of the washing machine.

[0044] In some embodiments, in step S104, if it is determined that the inequality m1-m0≥n1 is not true, then it is further determined whether the inequality m2-m0≥n3 is true, where n3 is a third preset turbidity difference value. If yes, then the water is drained to a preset drainage level lower than the current water level in the drum, water is refilled to the set water level in the drum, detergent is added, and the washing program continues; if no, then detergent is added, and the washing program continues. When the stirring process fails to separate dirt from clothes and there is no significant increase in turbidity, the turbidity after settling can be compared with the turbidity before washing to avoid affecting the washing effect.

[0045] Optionally, before step S101, it is determined whether the clothing is light-colored. If so, water is added and a preset weight of detergent is added, then the process proceeds to step S101; otherwise, the process proceeds directly to step S101. When the clothing is light-colored, a small amount of detergent can be added first for washing, stirring, and letting it stand. The remaining amount of detergent is added during subsequent washing processes to ensure the washing effect of light-colored clothing.

[0046] In some embodiments, when water is introduced to a preset overflow level higher than the current water level in the drum, the inlet valve is opened to begin water intake. Water continues to flow until the preset overflow level is reached, at which point a timer begins. Water intake and overflow occur simultaneously. When the timer reaches a third preset time, the inlet valve is closed to stop water intake. The inlet valve contains a built-in solenoid valve. When the washing machine needs water, the control circuit energizes the electromagnetic coil, generating a strong magnetic field that attracts the electromagnet, opening the valve. When water intake is not needed, the current is disconnected, the magnetic field disappears, the electromagnet is released, and the valve closes. The inlet valve consists of an electromagnet, a reed, and the solenoid valve itself. When the electromagnet is energized, the reed is attracted, opening the solenoid valve; when the power is off, the reed is released, closing the solenoid valve.

[0047] Optionally, when the current water level in the drum reaches the preset overflow level, water continues to enter, and the washing water in the drum flows out from the overflow port of the washing machine. The water flow is adjusted by controlling the rotation of the washing drum drive motor. The overflow port can be an existing overflow port of the washing machine, such as an overflow port for overflowing foam. The overflow port can also be a newly added overflow port specifically for overflowing floating dirt.

[0048] In some embodiments, the washing tub drive motor is controlled to rotate unidirectionally or bidirectionally; and / or, the washing tub drive motor is controlled to stop rotating. Due to the high water level, the motor rotates at a low speed, ensuring stable operation. Switching between unidirectional and bidirectional rotation allows for adjustment of the water inlet flow. Alternatively, the motor's start and stop can be controlled to adjust the water inlet flow.

[0049] Optionally, the current turbidity of the washing water in the drum can be detected by a turbidity sensor; and / or, the current or speed of the washing drum drive motor can be detected to calculate the current turbidity of the washing water in the drum. The working principle of a turbidity sensor is mainly based on the optical transmission method, using Bell-Lambert's law to measure the concentration of suspended particulate matter in water. The sensor typically contains a light source and a light receiver. The light emitted by the light source passes through the water sample, and the light is scattered and absorbed as it passes through the suspended particles in the water. The intensity of the transmitted light is directly proportional to the concentration of particulate matter in the water; the more particles, the less light is transmitted. Specifically, when light passes through the water sample, some light is scattered by the particles, and some light passes through. The receiver measures the intensity of the transmitted light and calculates the turbidity of the water sample by calculating the intensity of the scattered light. Turbidity sensors typically use infrared pairs as the light source and receiver, measuring the intensity of the transmitted light and converting it into a current magnitude, which is directly proportional to the degree of turbidity of the water.

[0050] In addition, turbidity sensors can also employ other principles, such as laser scattering and ultrasonic methods. Laser scattering turbidity sensors measure particle concentration by utilizing the scattering of particles from a laser beam in water; they are suitable for turbidity measurement in various media and offer high accuracy, but are also more expensive. Ultrasonic turbidity sensors infer turbidity by measuring the characteristics of sound wave propagation in liquids, making them suitable for measuring clear water.

[0051] The current turbidity of the washing water in the drum can be the turbidity at a specific point in time, or the average turbidity at multiple points in time. For example, 2-10 turbidity data points are collected every second, and then the turbidity data obtained throughout the process are averaged to obtain the average turbidity value of the current washing water.

[0052] The laundry washing method provided in this embodiment detects the turbidity values ​​m0, m1, and m2 of the washing water at three points: before washing, after stirring, and after settling. By comparing whether the inequalities m1-m0≥n1 and |m2-m1|≥n2 hold true, the type of dirt present in the washing water inside the drum can be determined. If the dirt in the washing water is light dirt such as lint, it can be cleaned and discharged by overflowing water. Overflowing water while adding water can prevent secondary contamination of clothes by light dirt such as lint. If the dirt in the washing water is heavy dirt such as dust, it can be cleaned and discharged by draining water. New water is added on top of the remaining clean water for subsequent washing operations, saving the water required to clean dirt. It effectively cleans dirt that floats on the water or sinks to the bottom during the soaking process, ensuring the washing effect of clothes. It eliminates the need to drain the soaking water and refill a large amount of water, thus avoiding water waste, improving the user experience, and enhancing the product competitiveness of the washing machine.

[0053] Example 2

[0054] This embodiment provides a clothing washing system. The clothing washing system provided by this embodiment can execute the clothing washing method provided by this embodiment, and has the corresponding functional modules and beneficial effects of executing the method.

[0055] like Figure 2 As shown, the laundry washing system includes a turbidity detection module 301, a water level detection module 302, a water inlet module 303, a drainage module 304, a timing module 305, a first judgment module 306, a second judgment module 307, and a control module 308. The turbidity detection module 301 detects the current turbidity of the washing water in the drum. The water level detection module 302 detects the current water level in the drum. The water inlet module 303 introduces water into the washing drum. The drainage module 304 drains water from the washing drum. The timing module 305 calculates the time. The first judgment module 306 determines whether the inequality m1 - m0 ≥ n1 is true. The second judgment module 307 determines whether the inequality |m2 - m1| ≥ n2 is true.

[0056] If the first judgment module 306 determines that the inequality m1-m0≥n1 is true, and the second judgment module 307 determines that the inequality |m2-m1|≥n2 is true, then the drain module 304 drains water to a preset drain level lower than the current water level in the drum, the water inlet module 303 refills water to the set water level in the drum, detergent is added, and the washing program continues to be executed through the control module 308; if the first judgment module 306 determines that the inequality m1-m0≥n1 is true, and the second judgment module 307 determines that the inequality |m2-m1|≥n2 is not true, then the water inlet module 303 fills water to a preset overflow level higher than the current water level in the drum, the water inlet and overflow occur simultaneously for a third preset time, the drain module 304 drains water to a preset drain level lower than the current water level in the drum, the water inlet module 303 refills water to the set water level in the drum, detergent is added, and the washing program continues to be executed through the control module 308.

[0057] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the above-described division of functional modules is merely an example. In practical applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the device can be divided into different functional modules to complete all or part of the functions described above. The specific working process of the functional modules described above can be referred to the corresponding process in the foregoing method embodiments, and will not be repeated here.

[0058] The laundry washing system provided in this embodiment detects the turbidity values ​​m0, m1, and m2 of the washing water at three points: before washing, after stirring, and after settling. By comparing whether the inequalities m1-m0≥n1 and |m2-m1|≥n2 hold true, the system can determine the type of dirt present in the washing water inside the drum. If the dirt is light lint or similar material, it can be removed by overflowing water. Simultaneous water intake and overflow prevents secondary contamination of clothes by light lint or similar material. If the dirt is heavy dust or similar material, it can be removed by draining water. New water is then added to the remaining clean water for subsequent washing operations, saving water needed for cleaning dirt. This effectively removes dirt that floats on the water or sinks to the bottom during soaking, ensuring the washing effect of the clothes. It eliminates the need to drain the soaking water and refill with large amounts of water, thus avoiding water waste, improving the user experience, and enhancing the product competitiveness of the washing machine.

The computer system may further include other removable / non-removable, volatile / non-volatile computer system storage media. By way of example only, the storage system may be used to read and write non-removable, non-volatile magnetic media (commonly referred to as a "hard disk drive"). Disk drives for reading and writing to removable non-volatile disks (e.g., "floppy disks") and optical disc drives for reading and writing to removable non-volatile optical discs, such as compact disc read-only memory (CD-ROM), digital video disc read-only memory (DVD-ROM), or other optical media, may be provided. In these cases, each drive may be connected to bus 404 via one or more data media interfaces. The storage device may include at least one program product having a set (e.g., at least one) of program modules configured to perform the functions of the embodiments of the present invention.

[0070] A program / utility having a set (at least one) of program modules can be stored in, for example, a storage device. Such program modules include, but are not limited to, an operating system, one or more application programs, other program modules, and program data. Each or some combination of these examples may include an implementation of a network environment. The program modules typically perform the functions and / or methods described in the embodiments of this invention.

[0071] The computer system can also communicate with one or more external devices (e.g., keyboard, pointing terminal, monitor, etc.), one or more terminals that enable users to interact with the computer system, and / or any terminal that enables the computer system to communicate with one or more other computing terminals (e.g., network interface card, modem, etc.). This communication can be performed via input / output (I / O) interfaces. Furthermore, the computer system can communicate with one or more networks (e.g., local area network (LAN), wide area network (WAN), and / or public networks, such as the Internet) via a network adapter. The network adapter communicates with other modules of the computer system via a bus. It should be understood that, although not shown in the figures, other hardware and / or software modules can be used in conjunction with the computer system, including but not limited to: microcode, terminal drivers, redundant processors, external disk drive arrays, Redundant Arrays of Independent Disks (RAID) systems, tape drives, and data backup storage systems.

[0072] The processor executes various functional applications and data processing by running programs stored in the storage device, such as implementing the laundry washing method provided in the embodiments of the present invention. The method includes: detecting the turbidity of the washing water in the drum to obtain turbidity values ​​at different time points; comparing the turbidity values ​​at different time points to determine whether there are dirt and the type of dirt in the washing water in the drum; and performing different cleaning operations according to the different types of dirt. For example, if there are dirt in the washing water in the drum and the type of dirt is floating dirt, then an overflow cleaning operation is performed; if there are dirt in the washing water in the drum and the type of dirt is sediment, then a drainage cleaning operation is performed; and if there are no dirt in the washing water in the drum, then a washing operation is performed. If the dirt in the washing water is light and grime like lint, it can be drained by overflowing. Simultaneous filling and overflowing prevents secondary contamination of clothes by these light particles. If the dirt is heavier and grime like dust, it can be drained by draining. New water can then be added on top of the remaining clean water for subsequent washing operations. This saves water needed for cleaning dirt and effectively removes dirt that floats or sinks during soaking, ensuring good washing results. It eliminates the need to drain the soaking water and refill with large amounts of water, thus saving water and improving the user experience and competitiveness of the washing machine.

[0073] For example, the method of washing clothes includes the following steps:

[0074] S101. Water is introduced into the drum to set the water level, and the current turbidity of the washing water in the drum is detected to obtain the first turbidity value m0;

[0075] S102. After the first preset time for the washing water in the mixing drum, the current turbidity of the washing water in the drum is detected to obtain the second turbidity value m1.

[0076] S103. After the washing water in the drum has been left to stand for a second preset time, the current turbidity of the washing water in the drum is detected to obtain the third turbidity value m2.

[0077] S104. Determine whether the inequality m1-m0≥n1 is true, where n1 is the first preset turbidity difference. If yes, proceed to step S105.

[0078] S105. Determine whether the inequality |m2-m1|≥n2 is true, where n2 is the second preset turbidity difference. If yes, drain water to a preset drain level lower than the current water level in the drum, refill water to the set water level in the drum, add detergent, and continue the washing program. If no, refill water to a preset overflow level higher than the current water level in the drum, and after a third preset time for both water inlet and overflow, drain water to a preset drain level lower than the current water level in the drum, refill water to the set water level in the drum, add detergent, and continue the washing program.

[0079] By detecting the turbidity values ​​(m0, m1, and m2) of the washing water at three points—before washing, after agitation, and after settling—and comparing whether the inequalities m1-m0≥n1 and |m2-m1|≥n2 hold true, the type of dirt present in the washing water inside the drum can be determined. If the dirt in the washing water is light lint or similar debris, it can be cleaned and drained by overflowing water. Simultaneous water intake and overflow prevents secondary contamination of clothes by these light lint or similar debris. If the dirt in the washing water is heavy dust or similar debris, it can be cleaned and drained by draining water. New water is then added to the remaining clean water for subsequent washing operations, saving water needed for cleaning dirt. This effectively removes dirt that floats on or sinks during soaking, ensuring the washing effect of the clothes. It eliminates the need to drain the soaking water and refill with large amounts of water, thus saving water resources, improving the user experience, and enhancing the product competitiveness of the washing machine.
