Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0050] The embodiments of the present application provide a washing machine, a control method thereof, a control device, and a storage medium to solve the problem that the sterilization duration of the existing washing machine increases with the increase in the dirtiness of the load, resulting in a long washing time and poor user experience. The following will be described with reference to the accompanying drawings.

[0051] The control method of the washing machine provided by the embodiments of the present application, the washing machine includes a connected washing tub 4 and a circulation pipeline 5. A sterilization module 6 and a circulation pump are provided on the circulation pipeline 5. The circulation pump is used to push the washing solution to circulate in the washing tub 4 and the circulation pipeline 5. The sterilization module 6 is used to sterilize the washing solution flowing through it. Please refer to Figure 1 , the method includes the following steps:

[0052] Step S101: When the washing machine enters the rinsing stage and meets the sterilization conditions, control the sterilization module 6 and the circulation pump to turn on;

[0053] Step S102: After a first preset duration, obtain the first turbidity value of the washing solution;

[0054] Step S103: If the first turbidity value is greater than the first preset turbidity value, control the circulation pump to increase by a first preset speed based on the current operating speed;

[0055] Step S104: After a second preset duration, control the sterilization module 6 and the circulation pump to turn off; wherein, the first preset speed is positively correlated with the first turbidity value.

[0056] The control method of the washing machine provided by the embodiment of the present application, when the washing machine meets the sterilization condition and the sterilization module is turned on for the first preset duration, obtains the first turbidity value of the washing solution, and judges the degree of dirt of the current load through the turbidity value of the washing solution. If the first turbidity value is greater than the first preset turbidity value, it indicates that the degree of dirt of the current load is still relatively heavy. Therefore, at this time, the control circulation pump increases the first preset speed based on the current operating speed. By increasing the speed of the circulation pump, the flow rate of the washing solution on the washing tub 4 and the circulation pipeline 5 is accelerated, and then the frequency of the washing solution flowing through the sterilization module 6 is increased, so as to improve the sterilization efficiency of the sterilization module for the washing solution within the same time. Among them, the first preset speed is positively correlated with the first turbidity value, that is, the higher the first turbidity value, the higher the increase in the first preset speed, thus ensuring the sterilization effect without extending the sterilization time, improving the sterilization efficiency, making the washing time the same each time, facilitating the user to better manage time and enabling the user to perform the next operation on the washed load in a timely manner.

[0057] Optionally, before controlling the sterilization module 6 and the circulation pump to start in step S101, the method includes: obtaining the mass information of the load, and determining the target water level, target speed, and target number of rinsing times based on the mass information; controlling the washing machine to perform the rinsing operation with the target number of rinsing times according to the target water level and target speed; if the current number of rinsing times is the last time, it is determined that the washing machine meets the sterilization condition. It can be understood that the above load is the laundry to be rinsed.

[0058] Based on the mass information of the laundry to be rinsed, determine the target water level, target speed, and target number of rinsing times in the rinsing stage, so that the water inflow matches the mass of the clothes, which not only ensures the cleaning effect but also avoids wasting water resources or electrical resources. At the same time, the target speed is the speed of the washing tub 4. By setting the speed of the washing tub 4 to match the mass of the clothes, it is prevented that the speed of the washing tub 4 is too high, resulting in unnecessary wear of the clothes, or the speed of the washing tub 4 is too low to thoroughly clean the dirt. It can be understood that the greater the mass of the clothes, the more the target number of rinsing times, and the smaller the mass of the clothes, the fewer the target number of rinsing times.

[0059] Among them, when the current number of rinsing times is the last time, it is determined that the washing machine meets the sterilization condition, and the laundry is sterilized during the last rinsing operation, so as to completely eliminate the remaining bacteria, molds, and allergens in the last link of the laundry washing process, avoid the remaining bacteria, molds, or allergens, and at the same time take into account safety and laundry care. Avoid turning on sterilization during the washing process. Although stains and some bacteria are removed, the humid environment and detergent residues may breed microorganisms (such as Escherichia coli, Staphylococcus aureus, etc.), resulting in incomplete sterilization. At the same time, it also shortens the sterilization duration and the number of sterilizations, saves energy, and improves the sterilization efficiency.

[0060] Optionally, after controlling the washing machine to perform the rinsing operation for the target number of rinsing times according to the target water level and the target rotation speed, the method includes: obtaining a second turbidity value of the washing solution; adjusting the running rotation speed of the washing tub based on the second turbidity value.

[0061] Optionally, adjusting the running rotation speed of the washing tub based on the second turbidity value includes: if the second turbidity value is greater than a second preset turbidity value, controlling the washing tub to increase the second preset rotation speed based on the current target rotation speed; if the second turbidity value is less than or equal to the second preset turbidity value, maintaining the current running rotation speed of the washing tub; wherein, the second preset turbidity value is greater than the first preset turbidity value.

[0062] That is, when the turbidity value of the washing solution is large and greater than the second preset turbidity value, it indicates that the degree of dirt on the clothes is relatively high. At this time, the rotation speed of the washing tub 4 is increased to increase the flow rate of the washing solution, thereby increasing the flushing force of the washing solution on the clothes and improving the cleaning effect in the rinsing stage. No further limitation is made on the second preset rotation speed here. In some examples, the rotation speed of the washing tub 4 may include multiple gears with sequentially increasing rotation speeds, such as the first gear, the second gear, the third gear, the fourth gear, and the fifth gear. At this time, increasing the second preset rotation speed may be to increase one gear based on the current gear. For example, if the current is the second gear, then increase one gear from the current gear to the third gear.

[0063] If the second turbidity value is less than or equal to the second preset turbidity value, it indicates that the current rotation speed can meet the cleaning force for the current dirt degree of the clothes and there is no need to increase the speed. Therefore, the current running rotation speed of the washing tub is maintained.

[0064] Optionally, determining the target water level and the target rotation speed based on the quality information includes: determining the target water level based on the quality information; determining the target rotation speed according to the target water level based on the mapping relationship between the water level and the rotation speed; wherein, the water level includes at least three water level intervals, and each water level interval corresponds to a rotation speed of the washing tub 4. That is, the target water level can be determined based on the quality information of the clothes first, and then the target rotation speed can be determined according to the determined target water level.

[0065] Optionally, in step S103, controlling the circulation pump to increase the first preset rotation speed based on the current running rotation speed includes: calculating the difference between the first turbidity value and the first preset turbidity value; determining the first preset rotation speed according to the difference based on the mapping relationship between the difference and the rotation speed; wherein, the difference includes multiple difference intervals, and each difference interval corresponds to a rotation speed.

[0066] That is, after the sterilization module 6 is turned on for a period of time, the running rotation speed of the circulation pump can be adjusted by the difference between the first turbidity value and the first preset turbidity value of the washing solution. It can be understood that the greater the difference between the first turbidity value and the first preset turbidity value, the greater the increased first preset rotation speed, so as to ensure the frequency of the washing solution flowing through the sterilization module 6, thereby improving the sterilization effect.

[0067] Optionally, after obtaining the first turbidity value of the washing solution in step S102, the method further includes: if the first turbidity value is less than or equal to the first preset turbidity value, controlling the circulation pump to maintain the current operating speed.

[0068] That is, after the sterilization module 6 is turned on for a period of time, if the first turbidity value is less than or equal to the first preset turbidity value, it indicates that the current operating speed of the circulation pump can meet the cleaning requirements and there is no need to increase the speed, so the current operating speed can be maintained.

[0069] Optionally, the sterilization module 6 can be a UV sterilization module 6. UV (ultraviolet) sterilization is a physical disinfection method that destroys the DNA / RNA structure of bacteria and viruses through ultraviolet light of a specific wavelength (usually UVC, wavelength 200 - 280 nm), making them lose their reproductive ability, thereby achieving the sterilization effect. By adopting the UV sterilization module 6, more than 99% of common bacteria (such as Escherichia coli, Staphylococcus aureus), molds (such as Aspergillus niger) and some viruses can be killed. And this kind of sterilization method is pure physical sterilization, unlike ozone or silver ions that may remain, which is suitable for infants, young children and people with sensitive skin. At the same time, it does not rely on high temperature and is suitable for heat-sensitive clothes such as wool, silk and underwear, and will not cause clothes to fade or deform like bleach or high-temperature washing. And, compared with high-temperature sterilization (which needs to be heated to above 60°C), UV sterilization consumes less power.

[0070] The embodiment of the present application also provides a washing machine. Please refer to Figure 4 , the washing machine includes a washing tub 4, a circulation pipeline 5. The circulation pipeline 5 is provided with a sterilization module 6 and a circulation pump.

The method includes the following steps: when the washing machine enters the rinsing stage and meets the sterilization conditions, controlling the sterilization module 6 and the circulation pump to be turned on; after a first preset time period, obtaining the first turbidity value of the washing solution; if the first turbidity value is greater than the first preset turbidity value, controlling the circulation pump to increase the first preset speed based on the current operating speed; after a second preset time period, controlling the sterilization module 6 and the circulation pump to be turned off; wherein, the first preset speed is positively correlated with the first turbidity value.

[0071] Optionally, the circulation pipeline 5 can be connected below the door seal so that the washing solution can flush the door seal when flowing through the door seal.

[0072] The embodiment of the present application also provides a control device of a washing machine. The washing machine includes a connected washing tub 4 and a circulation pipeline 5. The circulation pipeline 5 is provided with a sterilization module 6 and a circulation pump.
