Detailed Implementation

[0051] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0052] Referring to Figure 1, the bubble generating device 100 according to an embodiment of this application is used in a washing device. The bubble generating device 100 includes a dissolved air chamber 10, which has a liquid inlet 11, a liquid outlet 12, and a first air inlet 13. Specifically, the dissolved air chamber 10 may have a cavity. Water can be introduced into the cavity of the dissolved air chamber 10 through the liquid inlet 11, and gas can be introduced into the dissolved air chamber 10 through the first air inlet 13. When water is introduced into the dissolved air chamber 10 through the liquid inlet 11, the dissolved air chamber 10 can be pressurized, which facilitates the rapid dissolution of the gas in the dissolved air chamber 10 and increases the gas content in the water. The water containing dissolved gas can be discharged from the liquid outlet 12. The liquid inlet 11 can be connected to a tap water source or a water tank.

[0053] The bubble generating device 100 also includes a special gas generating module 20, which is used to provide a gaseous medium and is connected to the first air inlet 13. The special gas generating module 20 can be configured to generate a single gaseous medium or a mixture of multiple components through a reaction. For example, the special gas generating module 20 can be an ozone generator, an oxygen generator, an ion generator, an electrolysis module, etc.

[0054] The bubble generating device 100 also includes an aerator 30, which is connected to the liquid outlet 12. Specifically, the gas-liquid mixture in the dissolved gas chamber 10 enters the aerator 30 from the liquid outlet 12. The aerator 30 has a throttling effect, making the inflow velocity of the dissolved gas chamber 10 greater than the outflow velocity. The pressure in the dissolved gas chamber 10 continuously increases during the water inflow process, improving the gas solubility. When the dissolved gas water flows through the aerator 30, the gas is released in a cavitation manner during the throttling process, generating water containing a large number of microbubbles. By utilizing the mass transfer capacity and volume-enhancing characteristics of the microbubbles containing the gas medium, the gas medium is introduced into the washing equipment for disinfection, sterilization, and washing assistance.

[0055] According to the bubble generating device 100 of the present application embodiment, by setting a special gas generating module 20, special gas media such as hydrogen, oxygen, and ozone can be generated through reaction and supplied to the dissolved gas chamber 10. The bubbler 30 performs throttling and cavitation to generate microbubble water containing special gas media, thereby improving the washing efficiency and washing effect of the washing equipment.

[0056] For example, the washing equipment can be a dishwasher, a fruit and vegetable cleaner, a washing machine, etc.

[0057] The special gas generating module 20 can generate a special gas medium through a reaction. This special gas medium is a mixed medium that increases the content of one or more components in standard air, such as generating ozone, oxygen, hydrogen, or plasma. Specifically, the special gas generating module 20 can react via electrolysis, for example, by electrolyzing water to generate hydrogen, oxygen, or plasma; or, the special gas generating module 20 can be an ozone generator, supplying ozone to the dissolved gas chamber 10 to generate ozone-containing microbubble water, which can sterilize, disinfect, and deodorize the washing equipment, thus enhancing its efficiency; or, for example, the special gas generating module 20 can be an ion generator, generating a large number of negative ions and ozone through a reaction for sterilization and disinfection of the washing equipment.

[0058] When the special gas generating module 20 is an oxygen generator or an ion generator, air can be used as the air intake source. That is, the special gas generating module 20 can be equipped with an inlet, through which air is introduced into the special gas generating module 20. The special gas generating module 20 can have one inlet, which can be connected to the atmosphere, that is, air is drawn from the atmosphere and reacted. Alternatively, the inlet can be connected to the dissolved gas chamber 10, using the air in the dissolved gas chamber 10 as the air intake source. Of course, the special gas generating module 20 can have two inlets, one of which can be connected to the atmosphere and the other of which can be connected to the dissolved gas chamber 10. Different inlets can be selected to introduce air into the special gas generating module 20 according to actual usage requirements.

[0059] In some embodiments of this application, referring to Figure 2, the special gas generating module 20 includes a first inlet 21 for introducing air. Air can be supplied to the special gas generating module 20 through the first inlet 21, enabling the module to decompose air into ozone, negative ions, etc. Introducing air into the special gas generating module 20 through the first inlet 21 simplifies the structure of the bubble generating device 100 and enriches the washing modes of the washing equipment.

[0060] In some embodiments of this application, referring to Figure 2, the special gas generating module 20 includes a second inlet 22, which is used to introduce the medium into the dissolved gas chamber 10. A gas source can be provided to the special gas generating module 20 through the second inlet 22. When the special gas generating module 20 operates, it can decompose air into ozone, negative ions, etc., increasing the concentration of the special gas medium in the dissolved gas chamber 10, thereby increasing the content of special gases in the microbubble water to meet the diverse usage needs of the washing equipment. Furthermore, introducing air into the special gas generating module 20 through the second inlet 22 simplifies the structure of the bubble generating device 100 and enriches the washing modes of the washing equipment.

[0061] Referring to Figure 3, in some embodiments of this application, the special gas generating module 20 includes a first inlet 21 and a second inlet 22. The first inlet 21 is used to introduce air, and the second inlet 22 is connected to the dissolved gas chamber 10 for introducing the medium within the dissolved gas chamber 10. A gas source can be provided to the special gas generating module 20 through the first inlet 21 and the second inlet 22. For example, depending on different usage scenarios, air can be introduced into the special gas generating module 20 from the first inlet 21, or the medium from the dissolved gas chamber 10 can be introduced into the special gas generating module 20 from the second inlet 22, enriching the washing modes of the washing equipment.

[0062] For example, the special gas generating module 20 can be an ozone generator, which supplies ozone to the dissolved air chamber 10, generating ozone-containing microbubble water via the aerator 30. In regular washing programs, the required ozone concentration is low, and air can be supplied to the special gas generating module 20 through the first inlet 21. When the washing equipment requires sterilization, or when contaminants on tableware are difficult to clean, the medium of the dissolved air chamber 10 can be supplied to the ozone generator through the second inlet 22. In other words, the gas within the dissolved air chamber 10 serves as the air source for the special gas generating module 20, increasing the ozone concentration within the dissolved air chamber 10 and thus enhancing the ozone content in the microbubble water to meet the diverse usage needs of the washing equipment.

[0063] In some embodiments of this application, the bubble generating device 100 further includes an air pump 41, which is connected between the special gas generating module 20 and the dissolved gas chamber 10, and configured to pump the gas generated by the special gas generating module 20 to the dissolved gas chamber 10. The air pump 41 can deliver the gas generated by the special gas generating module 20 to the dissolved gas chamber 10, thereby improving the operational stability of the bubble generating device 100. Furthermore, the gas delivery speed can be adjusted by adjusting the power, flow rate, etc., of the air pump 41, thereby adjusting the concentration of the gas generated by the special gas generating module 20.

[0064] In some embodiments of this application, the second inlet 22 is connected to the upper part of the dissolved gas chamber 10 and is used to introduce the gaseous medium into the dissolved gas chamber 10. Specifically, when fluid is introduced into the dissolved gas chamber 10 through the liquid inlet 11, the pressure inside the dissolved gas chamber 10 will increase, and the gas in the upper part of the dissolved gas chamber 10 will be compressed. The connection of the second inlet 22 to the upper part of the dissolved gas chamber 10 facilitates the provision of a stable gas source for the special gas generating module 20, thereby improving the working efficiency of the special gas generating module 20.

[0065] In an embodiment where the special gas generating module 20 is equipped with a second inlet 22, the dissolved gas chamber 10, the special gas generating module 20, and the air pump 41 can be connected to form a circulation loop, with the air pump 41 driving the gas circulation within the loop. When it is necessary to increase the concentration of the gas medium, a gas source can be provided to the special gas generating module 20 through the second inlet 22. That is, the gas in the dissolved gas chamber 10 serves as the air intake source for the special gas generating module 20, and the air pump 41 serves as the power source for the circulation loop, enabling the gas to circulate within the loop and facilitating the increase of the gas medium concentration in the dissolved gas chamber 10. For example, the concentration of the gas medium can be adjusted according to the washing requirements of the washing equipment to increase the content of the gas medium in the microbubble water.

[0066] For example, a gas concentration detector 44 may be provided in the dissolved gas chamber 10. The gas concentration in the dissolved gas chamber 10 detected by the gas concentration detector 44 can be used to determine the air intake source, working status, and working parameters of the air pump 41 of the special gas generating module 20. In an embodiment where the special gas generating module 20 is provided with a first inlet 21 and a second inlet 22, the air intake source of the special gas generating module 20 can be switched between the first inlet 21 and the second inlet 22. When the gas concentration detected by the gas concentration detector 44 meets the target concentration, air can be introduced into the special gas generating module 20 through the first inlet 21. When the gas concentration detected by the gas concentration detector 44 does not meet the target concentration, the second inlet 22 can be switched to introduce gas into the dissolved gas chamber 10 into the special gas generating module 20, thereby increasing the concentration of the gas medium through a circulation loop.

[0067] Referring to Figures 1 to 3, in some embodiments of this application, a first inlet valve 42 is provided between the air pump 41 and the dissolved gas chamber 10. The first inlet valve 42 is used to introduce a gaseous medium into the dissolved gas chamber 10, and the first inlet valve 42 is a one-way valve. Specifically, the special gas generating module 20 generates a gaseous medium, which is introduced into the dissolved gas chamber 10 through the air pump 41 and then through the first inlet valve 42. Under the action of the one-way valve, the gaseous medium generated by the special gas generating module 20 can enter the dissolved gas chamber 10, preventing the gas in the dissolved gas chamber 10 from flowing out in reverse and improving the working stability of the bubble generating device 100.

[0068] In some embodiments of this application, the special gas generating module 20 is an ozone generator. The ozone generator can be used to supply ozone to the dissolved gas chamber 10 to form ozone-containing microbubble water, which facilitates disinfection, sterilization, and deodorization of the washing equipment, and can improve the washing effect of the washing equipment while reducing the amount of detergent used. Exemplarily, the ozone generator 20 can generate corona discharge through the electric field between the electrodes. The corona discharge generates a large number of free radicals and active oxygen, which react with oxygen molecules to generate ozone, and then supply it to the dissolved gas chamber 10.

[0069] In some embodiments of this application, the special gas generating module 20 is an ion generator. The ion generator can be used to supply plasma gas to the dissolved gas chamber 10, forming microbubble water containing plasma gas, which facilitates disinfection and sterilization of the washing equipment, improves the washing effect of the washing equipment, and reduces the amount of detergent used. Exemplarily, the ion generator may have at least two conductive electrodes. The voltage difference between the conductive electrodes generates an electric field. Under the action of the electric field, electrons dissociate from the negative electrode and ionize in the air, generating plasma gas.

[0070] Referring to Figures 1 to 3, in some embodiments of this application, the dissolved air chamber 10 further includes a second air inlet 14. The second air inlet 14 is equipped with a second air inlet valve 43, which is connected to the dissolved air chamber 10 and used to supply air to the dissolved air chamber 10. The second air inlet valve 43 is a one-way valve. Under the action of the one-way valve, air can enter the dissolved air chamber 10 from the outside, and the gas inside the dissolved air chamber 10 cannot flow out in the reverse direction. Air can be supplied to the dissolved air chamber 10 through the second air inlet valve 43, and microbubble water containing air is generated under the action of the dissolved air chamber 10 and the bubbler 30. For example, when the special gas generating module 20 is not working, air can be introduced into the dissolved air chamber 10 through the second air inlet valve 43. The dissolved air water is throttled and cavitated by the bubbler 30 to generate microbubble water containing ordinary air. The special gas generating module 20 can be turned on to generate microbubble water containing hydrogen, oxygen or ozone, etc., according to actual usage needs, or the special gas generating module 20 can be turned off to generate microbubble water containing ordinary air.

[0071] In addition, before water is introduced into the dissolved air chamber 10, air needs to be added to the dissolved air chamber 10. When the special gas generating module 20 is not started, air can be automatically added through the second air inlet valve 43. At this time, water introduced into the dissolved air chamber 10 produces microbubble water containing ordinary air. When the special gas generating module 20 and the air pump 41 are turned on, the special gas generating module 20 generates a gas medium that enters the dissolved air chamber 10. When water is introduced into the dissolved air chamber 10 again, microbubble water containing a special gas medium can be produced.

[0072] In addition, the concentration of the gas medium can be improved according to the efficiency requirements of the washing equipment, so as to increase the content of the gas medium in the microbubble water.

[0073] Referring to Figures 1 to 3, in some embodiments of this application, the bubble generating device 100 further includes a gas concentration detection element 44. The gas concentration detection element 44 is configured to detect the gas concentration within the dissolved gas chamber 10. The gas concentration detection element 44 facilitates the determination of the gas concentration within the dissolved gas chamber 10, allowing for adjustment of the parameters of the special gas generating module 20 according to actual usage requirements. For example, the washing equipment may have a conventional washing mode, a sterilization washing mode, a powerful washing mode, etc. Under different washing modes, bubble water containing different concentrations of gaseous media can be provided. By setting the gas concentration detection element 44, the gas concentration within the dissolved gas chamber 10 can be easily detected, allowing the gas generating device to generate microbubble water with the corresponding concentration by adjusting the parameters of the bubble generating module.

[0074] The washing device according to the embodiments of this application includes an inner tank 200 and the aforementioned bubble generating device 100. The inner tank 200 is provided with a washing chamber. The bubble generating device 100 is connected to the washing chamber. By coupling a special gas generating module 20 in the bubble generating device 100, the special gas generating module 20 can supply a gas medium to the dissolved gas chamber 10, which facilitates the generation of microbubble water containing the gas medium, thereby providing microbubble water containing the gas medium to the inner tank 200, improving the washing efficiency and washing effect of the washing device.

[0075] Referring to Figures 1 to 3, in some specific embodiments of the application, a special gas generating module 20 is provided in the bubble generating device 100. The special gas generating module 20 can generate ozone, oxygen, hydrogen, plasma gas media, etc. through reaction. The gas media generated by the special gas generating module 20 can be introduced into the dissolved gas chamber 10 through the first air inlet valve 42 via the air pump 41. Water is introduced into the dissolved gas chamber 10 through the liquid inlet 11, which can pressurize the dissolved gas chamber 10 without the need for a separate booster pump. This facilitates the rapid dissolution of the gas media in the dissolved gas chamber 10 and improves the solubility of the gas media in water. Finally, the gas is cavitated by the bubbler 30 to generate microbubbles.

[0076] The dissolved air chamber 10 is equipped with at least two air inlets. The first air inlet 13 is connected to the special gas generating module 20, which supplies special gas media such as ozone and plasma gas to the dissolved air chamber 10 for sterilization, disinfection, deodorization, and efficiency enhancement of the washing equipment. The second air inlet 14 is an air inlet. When the special gas generating module 20 is not turned on, air can be supplied to the dissolved air chamber 10 through the second air inlet 14 to generate microbubble water containing ordinary air. Microbubble water containing different components can be generated according to actual usage needs.

[0077] Additionally, the special gas generating module 20 may include a first inlet 21 and a second inlet 22. The first inlet 21 can be used to introduce air into the special gas generating module 20, and the second inlet 22 can be used to introduce the medium inside the dissolved gas chamber 10. A gas concentration detection element 44 is provided inside the dissolved gas chamber 10. Based on the gas concentration detected by the gas concentration detection element 44, the medium entering the dissolved gas chamber 10 through the first inlet 21 (air) or the second inlet 22 (gas) is determined. The air source of the special gas generating module 20 can be switched between air and the gas inside the dissolved gas chamber 10. The bubble generating device 100 also includes an air pump 41. The gas medium generated by the special gas generating module 20 enters the dissolved gas chamber 10 through the air pump 41. The residence time of the gas medium in the special gas generating module 20 can be controlled by the air pump 41. In addition, when it is necessary to increase the concentration of the gas medium, the gas in the dissolved gas chamber 10 can be used as the air source and supplied to the special gas generating module 20 through the second inlet 22. The dissolved gas chamber 10, the special gas generating module 20 and the air pump 41 form a circulation loop. The air pump 41 can also be used as the power source of the circulation loop. The number of cycles and the time can be determined according to the gas concentration detected by the gas concentration detector 44.

[0078] In related technologies, air disinfection and sterilization are generally the primary methods, such as hot air, air ionization modules, and ultraviolet lamps. However, these methods cannot effectively disinfect residual water in dishwashers. Even those that can disinfect residual water often rely on direct silver ion or water electrolysis modules, which can negatively impact water quality and reduce its quality. Therefore, this application also proposes a washing device, its sterilization and deodorization method and apparatus, and a storage medium. The following description, with reference to the accompanying drawings, illustrates embodiments of the washing device, sterilization and deodorization method and apparatus, and storage medium of this application.

[0079] Figure 4 is a schematic diagram of the structure of a washing device in one embodiment of this application.

[0080] As shown in Figure 4, the washing equipment includes a special gas generating module 20, an air pump 41, a water inlet valve 50, a dissolved gas chamber 10, and a washing chamber 210. The dissolved gas chamber 10 and the washing chamber 210 are interconnected. The bottom of the washing chamber 210 is equipped with a water cup 211 for storing residual water. The special gas generating module 20 and the air pump 41 are connected in series to the dissolved gas chamber 10. In some examples, the air inlet of the special gas generating module 20 can be connected to the dissolved gas chamber 10, while the air outlet is connected to the input end of the air pump 41, and the output end of the air pump 41 is also connected to the dissolved gas chamber 10. In this way, the gas in the dissolved gas chamber 10 can circulate through the special gas generating module 20 under the drive of the air pump 41, so as to quickly replace the gas in the dissolved gas chamber 10 with sterilizing gas.

[0081] Specifically, in this embodiment, an aerator 30 can be installed between the dissolved gas chamber 10 and the washing chamber 210 to fully dissolve the bactericidal gas in the dissolved gas chamber 10 into the water, and then replace the residual water in the water cup 211, which can further improve the bactericidal effect. Specifically, when the water containing the bactericidal gas flows through the aerator 30, the gas is released in a cavitation manner during the throttling process, generating water containing a large number of microbubbles. By utilizing the mass transfer capacity and volume-increasing characteristics of the microbubbles containing the gas medium, the gas medium enters the washing chamber 210 for disinfection, sterilization, and washing assistance.

[0082] This embodiment also includes other devices to improve the sterilization effect, including a first air inlet valve 42 and a second air inlet valve 43. The one-way valve prevents gas leakage from the dissolved gas chamber 10 and increases the pressure in the dissolved gas chamber 10 when water is introduced into it through the water inlet valve 50, thereby increasing the concentration of sterilizing gas in the water and improving the sterilization effect. It should be noted that the washing pump 220 in this embodiment controls the circulation of washing water in the washing chamber 210, thus washing and rinsing the items to be washed, such as dishes, in the washing chamber 210. The washing water and sterilizing / deodorizing gas can be combined and pressurized in the dissolved gas chamber 10, and then supplied to the washing chamber 210 through the aerator 30. When washing the items, the washing chamber 210 can be circulated and washed using the washing pump 220, and then the drain valve 212 is activated to discharge the washing water. Due to the filtration design, a water cup 211 is generally provided at the bottom of the washing chamber 210 to store residual water.

[0083] Figure 5 is a flowchart of a sterilization and deodorization method for a washing device in one embodiment of this application.

[0084] As shown in Figure 5, the sterilization and deodorization method for washing equipment includes the following steps:

[0085] S10, obtain the remaining running time of the washing equipment in the preset operating phase.

[0086] Specifically, if the residual water stored in the water cup 211 is not treated in a timely manner, bacteria may grow, thereby affecting the hygiene of the equipment components and the clothes to be washed. It should be noted that the washing equipment in this embodiment can be a dishwasher, washing machine, etc. For ease of description, the following embodiments can be described using a dishwasher as an example.

[0087] In the sterilization and deodorization method, it is first necessary to determine whether the washing equipment is in a preset operating stage to ensure that the residual water in the water cup 211 is no longer needed. For example, in some embodiments, the preset operating stage can be a drying stage, a storage stage, or a non-washing stage. This is because during the washing stage, the residual water in the water cup 211 is part of the normal process. After the washing stage is completed, the residual water in the water cup 211 can be drained to prevent bacterial growth. Each operating stage has a certain operating time, and the preset operating stage in this embodiment also has a corresponding operating time. Since sterilization and deodorization only replace the residual water in the water cup 211, and it is not necessary to replace the residual water continuously, but only once every certain period of time, this embodiment can first obtain the remaining operating time of the washing equipment in the preset operating stage, and then determine whether to replace the residual water based on the remaining operating time. If the remaining operating time is not much, it is not necessary to replace the residual water in the water cup 211 anymore.

[0088] S20, when the remaining running time is greater than the preset time, the control air pump 41 and the special gas generating module 20 are started to input sterilizing gas into the dissolved gas chamber 10.

[0089] Specifically, after obtaining the remaining running time of the washing equipment in the preset operating stage, this remaining running time can be compared with the preset time. It should be noted that the preset time can be the time corresponding to the residual water replacement frequency; in some embodiments, the preset time can range from 5 minutes to 60 minutes. When the remaining running time is greater than the preset time, it indicates that the current remaining running time is sufficient for the water cup 211 to replace the residual water once. Therefore, the air pump 41 and the special gas generating module 20 can be started, and the sterilizing gas generated by the special gas generating module 20 is pumped to the dissolved gas chamber 10. Since each air inlet in the dissolved gas chamber 10 is equipped with a one-way valve (the figure uses the first air inlet valve 42 and the second air inlet valve 43 as examples), the gas in the dissolved gas chamber 10 cannot be discharged to the external environment due to the presence of the one-way valves. In this embodiment, an additional air outlet is provided on the dissolved gas chamber 10 connected to the special gas generating module 20 to achieve gas circulation. After the air pump 41 and the special gas generating module 20 are started, the gas in the dissolved gas chamber 10 first flows out of the outlet under the action of the air pump 41, passes through the special gas generating module 20, and mixes with the sterilizing gas. Then, it passes through the air pump 41 and the first air inlet valve 42 and enters the dissolved gas chamber 10, thus completing the cycle. The special gas generating module 20 continuously generates sterilizing gas to increase the concentration of sterilizing gas in the dissolved gas chamber 10. In some embodiments, the sterilizing gas can be ozone gas.

[0090] S30, obtain the concentration of sterilizing gas in dissolved gas chamber 10.

[0091] Specifically, after the air pump 41 and the special gas generating module 20 are started, the gas concentration in the dissolved gas chamber 10 will increase. However, the gas concentration used for sterilization and deodorization in the washing equipment is not necessarily better the higher it is, but rather within a suitable range. Therefore, this embodiment also needs to detect the concentration of the sterilizing gas in the dissolved gas chamber 10. Specifically, the concentration of the sterilizing gas can be detected by a gas concentration detector 44 installed in the dissolved gas chamber 10. It should be noted that the gas concentration detector 44 can be controlled to open and close according to the on / off state of the air pump 41 and the special gas generating module 20, and does not need to be in the on / off state all the time.

[0092] S40, when the concentration of sterilizing gas is greater than or equal to the first preset concentration, control the air pump 41 and the special gas generating module 20 to shut down, and control the water inlet valve 50 to start, so that the sterilizing gas dissolves in water and is introduced into the washing chamber to replace the residual water in the water cup 211.

[0093] Specifically, when the concentration of the sterilizing gas in the dissolved gas chamber 10 is detected to be greater than or equal to the first preset concentration, it indicates that the current concentration of the sterilizing gas is sufficient for sterilization and deodorization. Therefore, the air pump 41 and the special gas generating module 20 can be shut off, and the water inlet valve 50 can be started to dissolve the sterilizing gas in the dissolved gas chamber 10 into the water. Then, the water containing the sterilizing gas is introduced into the washing chamber to replace the residual water in the water cup 211, thereby completing one sterilization and deodorization operation of the washing equipment. Optionally, in this embodiment, the water inlet valve 50 is started to introduce water, and the preferred water volume is 0.1-1 liter.

[0094] In one embodiment of this application, the washing device further includes a drain valve 212 connected to a water cup 211. The method further includes: when the remaining running time is less than or equal to a preset time, controlling the drain valve 212 to open to drain the residual water in the water cup 211.

[0095] Specifically, if the remaining running time of the washing equipment in the preset running phase is less than or equal to the preset time, it means that the remaining running time of the washing equipment in the preset running phase is not sufficient to perform another sterilization and deodorization operation. Therefore, the washing equipment does not need to perform sterilization and deodorization operation in the subsequent running time, so the residual water in the water cup 211 can be drained directly without needing to perform water intake operation.

[0096] In some embodiments of this application, before the control air pump 41 and special gas generating module 20 are started, the sterilization and deodorization method further includes: controlling the drain valve 212 to open to drain the residual water in the water cup 211.

[0097] Water containing disinfectant gas is introduced into the washing chamber to replace the residual water in water cup 211. Specifically, before the air pump 41 and the special gas generating module 20 are started, the residual water in water cup 211 is emptied. This ensures that when the water inlet valve 50 is opened to introduce water into the dissolved gas chamber 10 and the disinfectant gas is dissolved in the water, the water containing the disinfectant gas can be directly sent to water cup 211 to disinfect and deodorize water cup 211 and the environment in which water cup 211 is located.

[0098] In some embodiments of this application, as shown in FIG6, the method further includes, before the control air pump 41 and special gas generating module 20 are started:

[0099] S301, obtain the degree of dirtiness of water cup 211. S302, when the degree of dirtiness is greater than the first preset degree of dirtiness, control the air pump 41 and the special gas generating module 20 to start.

[0100] Specifically, to achieve more accurate sterilization and deodorization, this embodiment also includes a dirt sensor 2111 in the water cup 211. This dirt sensor 2111 can detect the degree of dirtiness in the water cup 211. Specifically, the dirt sensor 2111 can be one or more combinations of an odor sensor, an oxygen content sensor, a dissolved oxygen sensor in water, a water temperature sensor, and a water conductivity sensor. After obtaining the degree of dirtiness in the water cup 211, a judgment can be made. If the degree of dirtiness is greater than a first preset degree of dirtiness, the air pump 41 and the special gas generating module 20 can be restarted. That is to say, in this embodiment, the activation of the air pump 41 and the special gas generating module 20 requires the degree of dirtiness in the water cup 211 to be greater than the first preset degree of dirtiness. It can be understood that if the degree of dirtiness in the water cup 211 is less than or equal to the first preset degree of dirtiness, it means that the water cup 211 is not very dirty at present, so there is no need to perform subsequent sterilization and deodorization steps, and then return to step S10 to obtain the remaining running time of the washing equipment in the preset running stage.

[0101] In some embodiments of this application, as shown in FIG7, the sterilization and deodorization method of the washing equipment further includes:

[0102] S401, determine the comparative concentration of the sterilizing gas in the dissolved air chamber 10 based on the degree of dirtiness. S402, when the concentration of the sterilizing gas is greater than or equal to the comparative concentration, control the air pump 41 and the special gas generating module 20 to shut down, and control the water inlet valve 50 to start, so that the sterilizing gas dissolves in water and is introduced into the washing chamber to replace the residual water in the water cup 211.

[0103] Specifically, this embodiment can further classify the degree of dirtiness, that is, different degrees of dirtiness correspond to different concentrations of sterilizing gas. In this example, this is defined as a comparison concentration. It can be understood that the higher the degree of dirtiness, the higher the corresponding comparison concentration of sterilizing gas. More specifically, in a specific embodiment, when the degree of dirtiness is greater than or equal to a second preset degree of dirtiness, the comparison concentration is determined to be the second preset concentration; when the degree of dirtiness is less than the second preset degree of dirtiness, the comparison concentration is determined to be a third preset concentration, wherein the third preset concentration is less than the second preset concentration, and the second preset degree of dirtiness is greater than the first preset degree of dirtiness.

[0104] After determining the comparative concentration of the bactericidal gas in the dissolved gas chamber 10, the actual concentration of the bactericidal gas can be compared with the comparative concentration. When the concentration of the bactericidal gas is greater than or equal to the comparative concentration, it indicates that the bactericidal gas generated by the special gas generating module 20 is sufficient. Therefore, the air pump 41 and the special gas generating module 20 can be shut down, and then the water inlet valve 50 can be started to introduce water into the dissolved gas chamber 10. This allows the water containing the bactericidal gas to flow through the aerator 30 to the water cup 211 in the washing chamber 210, thus sterilizing and deodorizing the water cup 211 and the environment in which it is located.

[0105] In one specific embodiment of this application, as shown in Figure 8, when the washing equipment is in the drying or storage stage, the remaining running time of this stage is obtained. If the remaining running time is less than or equal to a preset time, the drain valve 212 can be started to stop the water intake until the end. If the remaining running time is greater than the preset time, the degree of dirtiness of the water cup 211 can be further obtained, and then it is determined whether to perform the sterilization and deodorization step based on the degree of dirtiness. When the degree of dirtiness is greater than or equal to a first preset degree of dirtiness, the drain valve 212 is opened to drain the water in the water cup 211, and then the drain valve 212 is closed, followed by the sterilization and deodorization step. When the degree of dirtiness is less than the first preset degree of dirtiness, the sterilization and deodorization step does not need to be performed, so the process returns to the step of obtaining the remaining running time. In the sterilization and deodorization process, the air inlet valve and the special gas generating module 20 are first turned on to increase the concentration of sterilizing gas in the dissolved air chamber 10. Then, the concentration of sterilizing gas is compared with the concentration of the water cup 211 based on the degree of dirtiness. The concentration of sterilizing gas in the dissolved air chamber 10 is then compared with the concentration of the comparison. When the concentration of sterilizing gas is less than the concentration of the comparison, the process returns to the step of comparing the degree of dirtiness and the second preset degree of dirtiness. When the concentration of sterilizing gas in the dissolved air chamber 10 is greater than or equal to the concentration of the comparison, the air pump 41 and the special gas generating module 20 are turned off, and the water inlet valve 50 is turned on. The water flowing into the dissolved air chamber 10 from the water inlet valve 50 can dissolve the sterilizing gas and then flow into the water cup 211 to sterilize and deodorize the water cup 211 and the environment in which the water cup 211 is located. The above steps are then repeated to obtain the remaining running time.

[0106] In summary, the sterilization and deodorization method for the washing equipment in this application embodiment can disinfect, sterilize, and deodorize the residual water in the washing equipment, improve the sterilization effect of the washing equipment and the user experience, while maintaining the stability of water quality.

[0107] Furthermore, this application also proposes a computer-readable storage medium storing a sterilization and deodorization program for a washing device, wherein when the program is executed by a processor, it implements the sterilization and deodorization method for the washing device described in any of the above embodiments.

[0108] The computer-readable storage medium of this application embodiment executes a sterilization and deodorization program for a washing device stored thereon via a processor.
