Detailed Implementation

[0023] The embodiments of this utility model 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 utility model, and should not be construed as limiting this utility model.

[0024] Combination Figure 1 According to an embodiment of the present invention, a bubble generating device 100 is used in a washing device. The bubble generating device 100 includes a gas dissolving chamber 10, which has a liquid inlet 11, a liquid outlet 12, and a first air inlet 13. Specifically, the gas dissolving chamber 10 may have a cavity. Water can be introduced into the cavity of the gas dissolving chamber 10 through the liquid inlet 11, and gas can be introduced into the gas dissolving chamber 10 through the first air inlet 13. When water is introduced into the gas dissolving chamber 10 through the liquid inlet 11, the gas dissolving chamber 10 can be pressurized, which facilitates the rapid dissolution of the gas in the gas dissolving 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.

[0025] The bubble generating device 100 also includes a gas generating module 20, which provides a gaseous medium and is connected to the first air inlet 13. The 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 gas generating module 20 can be an ozone generator, an oxygen generator, an ion generator, an electrolysis module, etc.

[0026] 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.

[0027] According to the embodiment of the present invention, the bubble generating device 100, by setting a gas generating module 20, can generate special gas media such as hydrogen, oxygen, and ozone through reaction and supply them to the dissolved gas chamber 10. Through the bubbler 30, cavitation is throttled to generate microbubble water containing special gas media, thereby improving the washing efficiency and washing effect of the washing equipment.

[0028] For example, the washing equipment can be a dishwasher, a fruit and vegetable cleaner, a washing machine, etc.

[0029] The gas generating module 20 can generate a special gaseous medium through a reaction. This special gaseous 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 gas generating module 20 can react via electrolysis, for example, by electrolyzing water to generate hydrogen, oxygen, or plasma; or, the 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 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.

[0030] When the gas generating module 20 is an oxygen generator or an ion generator, air can be used as the air intake source. That is, the gas generating module 20 can be equipped with an inlet, through which air is introduced into the gas generating module 20. The 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 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 gas generating module 20 according to actual usage requirements.

[0031] In some embodiments of this utility model, combined with Figure 2 The gas generating module 20 includes a first inlet 21 for introducing air. Air can be supplied to the gas generating module 20 through the first inlet 21. When the gas generating module 20 operates, it can decompose air into ozone, negative ions, etc. Introducing air into the 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.

[0032] In some embodiments of this utility model, combined with Figure 2 The gas generating module 20 includes a second inlet 22, which is used to introduce the medium into the dissolved gas chamber 10. Gas can be supplied to the gas generating module 20 through the second inlet 22. When the 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 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.

[0033] Combination Figure 3In some embodiments of this utility model, the 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 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 gas generating module 20 through the first inlet 21, or the medium from the dissolved gas chamber 10 can be introduced into the gas generating module 20 through the second inlet 22, thus enriching the washing modes of the washing equipment.

[0034] For example, the 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 a regular washing program, the required ozone concentration is low, and an air source can be provided to the gas generating module 20 through the first inlet 21. When the washing equipment requires sterilization, or when contaminants on the tableware are difficult to clean, the medium of the dissolved air chamber 10 can be provided to the ozone generator through the second inlet 22. That is, the gas in the dissolved air chamber 10 is used as the air source for the gas generating module 20 to increase the ozone concentration in the dissolved air chamber 10, thereby increasing the ozone content in the microbubble water to meet the diverse usage needs of the washing equipment.

[0035] In some embodiments of this invention, the bubble generating device 100 further includes an air pump 41, which is connected between the gas generating module 20 and the dissolved gas chamber 10, and configured to pump the gas generated by the gas generating module 20 to the dissolved gas chamber 10. The air pump 41 can improve the operational stability of the bubble generating device 100 by delivering the gas generated by the gas generating module 20 to the dissolved gas chamber 10. Furthermore, the gas delivery speed can be adjusted by adjusting the power and flow rate of the air pump 41, thereby adjusting the concentration of the gas generated by the gas generating module 20.

[0036] In some embodiments of this invention, 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 second inlet 22 is connected to the upper part of the dissolved gas chamber 10, which facilitates the provision of a stable gas source for the gas generating module 20 and improves the working efficiency of the gas generating module 20.

[0037] In an embodiment where the gas generating module 20 is equipped with a second inlet 22, the dissolved gas chamber 10, the 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 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 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 an increase in the concentration of the gas medium 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.

[0038] 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 gas generating module 20. In an embodiment where the gas generating module 20 is provided with a first inlet 21 and a second inlet 22, the air intake source of the 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 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 gas generating module 20, thereby increasing the concentration of the gas medium through a circulation loop.

[0039] Combination Figures 1 to 3 In some embodiments of this utility model, 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 gas medium into the dissolved gas chamber 10, and the first inlet valve 42 is a one-way valve. Specifically, the gas generating module 20 generates a gas 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 gas medium generated by the 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.

[0040] In some embodiments of this invention, the gas generating module 20 is an ozone generator. The ozone generator can supply ozone to the dissolved gas chamber 10, forming ozone-containing microbubble water, which facilitates disinfection, sterilization, and deodorization of the washing equipment, and can improve the washing effect of the equipment while reducing detergent usage. Exemplarily, the ozone generator 20 can generate corona discharge through the electric field between electrodes. The corona discharge generates a large number of free radicals and active oxygen, which react with oxygen molecules to generate ozone, which is then supplied to the dissolved gas chamber 10.

[0041] In some embodiments of this invention, the gas generating module 20 is an ion generator. The ion generator can 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, and reduces detergent usage. Exemplarily, the ion generator may have at least two conductive electrodes. The voltage difference between the conductive electrodes generates an electric field. Under the influence of the electric field, electrons dissociate from the negative electrode and ionize in the air, generating plasma gas.

[0042] Combination Figures 1 to 3 In some embodiments of this utility model, the dissolved air chamber 10 further includes a second air inlet 14, which is equipped with a second air inlet valve 43. The second air inlet valve 43 is connected to the dissolved air chamber 10 and is 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 in 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 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 containing dissolved air is cavitated by the bubbler 30 to generate microbubble water containing ordinary air. The gas generating module 20 can be turned on to generate microbubble water containing hydrogen, oxygen or ozone, etc., or the gas generating module 20 can be turned off to generate microbubble water containing ordinary air, depending on the actual usage requirements.

[0043] 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 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 gas generating module 20 and the air pump 41 are turned on, the 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.

[0044] 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.

[0045] Combination Figures 1 to 3In some embodiments of this utility model, 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 in the dissolved gas chamber 10. The gas concentration detection element 44 can easily determine the gas concentration in the dissolved gas chamber 10, and facilitate the adjustment of the parameters of the 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. In different washing modes, bubble water containing gas media of different concentrations can be provided. By setting the gas concentration detection element 44, it is easy to detect the gas concentration in the dissolved gas chamber 10, so that by adjusting the parameters of the bubble generating module, the gas generating device can generate microbubble water with the corresponding concentration.

[0046] The washing device according to the present invention 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 gas generating module 20 in the bubble generating device 100, the 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.

[0047] Combination Figures 1 to 3 In some specific embodiments of the utility model, a gas generating module 20 is provided in the bubble generating device 100. The gas generating module 20 can generate ozone, oxygen, hydrogen, plasma gas medium, etc. through reaction. The gas medium generated by the 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 medium in the dissolved gas chamber 10 and improves the solubility of the gas medium in water. Finally, the gas is cavitated by the bubbler 30 to generate microbubbles.

[0048] The dissolved air chamber 10 is equipped with at least two air inlets. The first air inlet 13 is connected to the gas generating module 20 and is used to supply ozone, plasma gas, or other special gas media 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 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.

[0049] Additionally, the 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 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 gas generating module 20 determines whether to introduce air from the first inlet 21 or the medium from the second inlet 22 into the dissolved gas chamber 10. The gas source of the gas generating module 20 can be switched between air and gas from the dissolved gas chamber. The bubble generating device 100 also includes an air pump 41. The gas medium generated by the gas generating module 20 enters the dissolved gas chamber 10 through the air pump 41. The residence time of the gas medium in the 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 gas generating module 20 through the second inlet 22. The dissolved gas chamber 10, the 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.
