[0023] 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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] In the description of the embodiments of this application, "module" and "processor" can include hardware, software, or a combination of both. A module can include hardware circuitry, various suitable sensors, communication ports, and memory, and may also include software components, such as program code, or a combination of software and hardware.

[0025] This application provides a washing machine and its control method, control device and storage medium to solve the problem that existing washing machines cannot remove tiny particles from clothes. The following description is in conjunction with the accompanying drawings.

[0026] The washing machine control method provided in this application embodiment includes a negative ion generator 7, a water inlet pipe, and a drum. The negative ion generator 7 is used to output negative ions to the water inlet pipe. For example, the water inlet pipe includes a Venturi tube. The negative ion generator 7 is connected to the negative pressure port of the Venturi tube. The negative ions generated by the negative pressure change within the Venturi tube are used to adsorb the negative ions generated by the negative ion generator 7. Please refer to [link to relevant documentation]. Figure 1 The method includes the following steps: Step S101: Obtain the weight information of the load; Step S102: Based on the weight information, determine the water inlet information and the target operating time of the negative ion generator 7, wherein the water inlet information includes the water inlet volume; Step S103: Control the water inlet pipe to supply water according to the water inlet flow rate and control the negative ion generator 7 to turn on; Step S104: After the target duration or after the water inlet pipe has finished filling, control the negative ion generator 7 to turn off.

[0027] Since fine particulate matter usually adheres to the surface of clothing fibers, and the heavier and more numerous the clothes inside the drum, the more fine particulate matter adheres to them. Furthermore, heavier clothes typically hold more water, requiring more water to achieve the same humidity level. This necessitates more negative ions to maintain a certain concentration in the water for effective sterilization. Therefore, the washing machine control method provided in this application determines the water intake and the target duration of the negative ion generator 7 based on the load weight information before water intake. This ensures that the water intake and the negative ions generated by the generator match the load weight, satisfying the cleaning requirements for fine particulate matter such as dust, pollen, and PM2.5 on the load while saving energy and avoiding waste.

[0028] Furthermore, negative ions mix thoroughly with water before entering the washing machine, forming "negative ion water." These negatively charged water molecules can penetrate deeper into the fibers more effectively and combine with positively charged dirt particles (such as grease and dust) earlier, thus improving cleaning efficiency from the initial washing stage, especially for highly adhesive micro-dust particles. Secondly, negative ions have a coagulating effect. If negative ions are injected before the water enters the drum, some tiny impurities in the water can be pre-flocculated and aggregated, theoretically partially intercepted at the inlet filter or more easily discharged, acting as a pre-treatment for the water. Finally, water rich in negative ions has smaller molecular clusters, lower surface tension, and stronger permeability and solubility, allowing detergents to dissolve and work more effectively, improving washing efficiency. Simultaneously, once the water inlet pipe is full, the negative ion generator is turned off to prevent leakage and accumulation of negative ions when there is no water flow.

[0029] Furthermore, different materials have varying surface requirements and responses to negative ions (e.g., rough materials like towels and cotton / linen have a larger surface area and more crevices where dirt can accumulate, requiring more negative ions and a longer exposure time to penetrate and kill bacteria, while smooth materials like silk and synthetic fibers are relatively easy to clean, requiring fewer negative ions and a shorter exposure time), different types of dirt require different concentrations of negative ions (e.g., more resistant bacterial spores or certain mold spores require higher concentrations of negative ions and longer exposure times), and different degrees of dirt require different concentrations of negative ions (e.g., lightly soiled areas have fewer microorganisms, requiring only a standard amount of negative ions and a shorter exposure time, while heavily soiled areas or areas with a musty smell after long-term storage have a large microbial load, and may even have formed a biofilm, requiring a significantly increased amount of negative ions to penetrate and thoroughly kill bacteria). Therefore, after determining the target duration of the negative ion generator based on the weight of the load, the target duration can be further adjusted based on the material of the clothing, the type of dirt, and the degree of dirt to better match the amount of negative ions with the cleaning needs of the load.

[0030] For example, if the clothing material is rough or heavily soiled, the preset time can be extended based on the target time; if the clothing material is smooth or only slightly soiled, the preset time can be shortened based on the target time. No further explanation is given here.

[0031] Optionally, determining the target operating time of the negative ion generator 7 includes: determining the required total amount of negative ions based on the weight information of the load; and determining the target operating time of the negative ion generator based on the amount of ions generated by the negative ion generator per unit time and the required total amount of negative ions. Specifically, dividing the required total amount of negative ions by the amount of ions generated by the negative ion generator per unit time yields the target operating time of the negative ion generator.

[0032] Optionally, the negative ion generator 7 is turned on when the water inlet pipe is in the water intake state to prevent negative ions from accumulating inside the washing machine and to avoid increasing the washing time by turning on the negative ion generator 7 alone. That is, the negative ion generator is turned on no earlier than the water inlet pipe is turned on, and the negative ion generator is turned off no later than the water inlet pipe is turned off. Preferably, the water inlet pipe and the negative ion generator 7 are turned on simultaneously.

[0033] Optionally, obtaining the weight information of the load includes: weighing the load and obtaining the mass of the load, and obtaining the weight information based on the mass of the load.

[0034] Optionally, please refer to Figure 2Step S103, controlling the water inlet pipe to supply water according to the water inlet volume, includes: Step S1031: determining the water inlet duration based on the target duration; Step S1032: determining the water inlet rate based on the water inlet duration and water inlet volume; Step S1033: controlling the water inlet pipe to supply water according to the water inlet rate and water inlet duration; wherein, the water inlet duration is greater than or equal to the target duration. Preferably, the water inlet duration is greater than the target duration, so that when the negative ion generator 7 is turned off, the negative ions generated by the negative ion generator 7 just before it is turned off have sufficient water flow as a carrier to carry all the negative ions into the cylinder.

[0035] Based on the determined water inlet time, the water inlet rate of the water inlet pipe is then determined to ensure that the water inlet rate of the water inlet pipe meets the target time for the negative ion generator 7 to be turned on. By limiting the water inlet time to be greater than or equal to the target time, the negative ion generator 7 is turned on only when the water inlet pipe is open, thereby further saving washing time and forming negative ion water to improve washing efficiency.

[0036] For example, if the target duration is T seconds, the water inlet duration is determined to be T+10 seconds, and the water inlet rate V is determined using the water inlet volume and the water inlet duration T+10 seconds.

[0037] Optionally, the water inlet pipeline includes a microbubble nozzle 6, the water outlet area of ​​the microbubble nozzle 6 is adjustable, and the water inlet pipeline is controlled to supply water according to the water inlet rate and water inlet duration, including: determining the target water outlet area of ​​the microbubble nozzle 6 based on the water inlet rate; and controlling the microbubble nozzle 6 to supply water with the target water outlet area and water inlet duration.

[0038] In some examples, the microbubble nozzle 6 may include an adjustable end panel, such as a shower head panel or outer ring, that can be rotated to adjust the water flow and water area, primarily by changing the effective number of water outlets to alter the water area. For example, the microbubble nozzle 6 includes four different water flow levels, each corresponding to a water area and a rated water inlet rate. Once the water inlet rate is determined, the water flow level of the microbubble nozzle 6 is further determined based on that rate. If the determined water inlet rate falls between two different rated water inlet rates, the water flow level corresponding to the lower rated water inlet rate is selected as the final water flow level to ensure that the water inlet duration is greater than or equal to the target duration. Simultaneously, a smaller rated water inlet rate corresponds to a smaller water area, generating more microbubbles and resulting in better cleaning.

[0039] Optionally, the water inlet pipeline may include a first water inlet path and a second water inlet path (not shown in the figure). The first water inlet path includes a Venturi tube 5, which is connected to the negative ion generator 7 and the microbubble nozzle 6. The second water inlet path includes a conventional pipeline, which is connected to the microbubble nozzle 6. When the water inlet time exceeds the target time, the target time can be inlet first through the first water inlet path, and then the remaining time can be inlet through the second water inlet path. This satisfies the requirement that negative ions can dissolve in water and enter the cylinder, while also shortening the overall water inlet time.

[0040] Optionally, the inlet pipeline includes an inlet valve, controlling the inlet pipeline to supply water at the inlet rate and for the duration thereof, including: determining the target opening degree of the inlet valve based on the inlet rate; and controlling the inlet valve to supply water at the target opening degree for the duration thereof. The type of inlet valve is not further limited here; for example, it can be a proportional valve or a servo control valve, whose valve can remain in any intermediate position between fully closed and fully open, thereby achieving precise and continuous control of the water flow.

[0041] It is understandable that different opening degrees of the inlet valve correspond to different inlet water rates. Once the inlet water rate of the inlet pipe is determined, the target opening degree of the inlet valve can be further determined based on the determined inlet water rate.

[0042] Optionally, the washing machine also includes an ozone generator for outputting ozone to the water inlet pipe. After obtaining the weight information of the load, the method further includes: determining the target duration of the water inlet information, the negative ion generator 7, and the ozone generator based on the weight information, wherein the water inlet information includes the water inlet volume; controlling the water inlet pipe to supply water according to the water inlet volume, and controlling the negative ion generator 7 and the ozone generator to turn on; and controlling the negative ion generator 7 and the ozone generator to turn off after the target duration or after the water inlet pipe has finished supplying water.

[0043] The washing machine may also include an ozone generator. The ozone gas produced by the ozone generator rapidly destroys the cell walls and enzyme systems of bacteria and viruses, causing them to die and improving the sterilization effect on the load. In some examples, ozone and negative ions can be introduced into the drum simultaneously during water intake to save water intake time.

[0044] Optionally, the washing machine also includes an ozone generator, which outputs ozone to the water inlet pipe. After obtaining the weight information of the load, the method further includes: determining water inlet information, the target duration of operation of the negative ion generator 7, and the operating duration of the ozone generator based on the weight information, wherein the water inlet information includes the water volume; controlling the water inlet pipe to supply water according to the water volume and controlling the ozone generator to turn on; controlling the ozone generator to turn off after the operating duration; controlling the negative ion generator 7 to turn on; and controlling the negative ion generator 7 to turn off after the target duration or after the water inlet pipe has finished supplying water.

[0045] In other examples, ozone can be introduced into the drum first to sterilize and disinfect the load. The strong oxidizing properties of ozone first destroy the cell walls of bacteria and viruses, decompose pigment molecules and organic stain molecules, and "peel" them off the clothes. Then, negative ions are introduced. The tiny residues produced after ozone decomposition, as well as the micro-dust inherent on the clothes, are wrapped by negative ions, which neutralize the charge and cause them to condense into larger particles, making them easier to be washed away by the water flow and preventing them from re-adhering to the clothes. This not only achieves deep disinfection and stain removal, but also enhances the ability to remove tiny particles of dirt. In addition, negative ions can also bring the additional benefits of eliminating static electricity and making clothes fluffier and softer.

[0046] By introducing ozone and negative ions sequentially, allowing them to operate at different times, interference between the two is avoided, and the slight risk of ozone potentially converting into nitrogen oxides under the corona discharge of the negative ion generator 7 is eliminated. In some examples, the ozone generator can be activated during the main wash stage for powerful disinfection and stain removal; the negative ion generator 7 can be activated during the rinsing or drying stage for particulate removal and fabric softening. In other examples, ozone and negative ions can be introduced sequentially during the main wash stage.

[0047] This application also provides a washing machine, including a drum, a water inlet pipe, and a negative ion generator 7. Please refer to... Figure 6 The water inlet pipe includes a venturi tube 5 and a microbubble nozzle 6. The microbubble nozzle 6 introduces water into the cylinder. The venturi tube 5 includes a water outlet and a negative pressure port. The water outlet is connected to the microbubble nozzle 6. The negative ion generator 7 is connected to the negative pressure port. The negative ion generator 7 is used to generate negative ions. When water flows through the venturi tube 5, negative ions are absorbed.

[0048] Negative ions generated by the negative ion generator 7 are drawn in through the negative pressure port of the Venturi tube 5. This not only automatically adds negative ions to the water inlet pipe but also allows them to mix with water to form negative ion water. This negative ion water can penetrate deeper into the fibers more effectively and combine with positively charged dirt particles (such as grease and dust) earlier, thus improving cleaning efficiency from the initial washing stage, especially for highly adhesive micro-dust particles. Secondly, negative ions have a coagulating effect. If negative ions are injected before the water enters the drum, some tiny impurities in the water can be pre-flocculated and aggregated, theoretically partially intercepted at the water inlet filter or more easily discharged, acting as a pre-treatment for the water. Finally, water rich in negative ions has smaller molecular clusters, lower surface tension, and stronger permeability and solubility, allowing detergents to dissolve and work more effectively and faster, thus improving washing efficiency.

[0049] Optionally, the washing machine provided in this embodiment further includes an ozone generator. The negative pressure port is connected to the ozone generator and the negative ion generator 7 via a three-way pipe. The ozone generator is used to generate ozone. The activation time of the ozone generator and the negative ion generator 7 is not further limited here. In some examples, the ozone generator and the negative ion generator 7 can be turned on simultaneously; in other examples, they can be turned on sequentially.
