Description

Technical Field

[0001] This invention relates to the field of washing technology, and more particularly to a bubble generating device and a washing apparatus having the bubble generating device. Background Technology

[0002] As living standards improve, people have higher and higher demands for quality of life, and consequently, higher requirements for kitchenware, aiming to simplify tedious housework. The cleanliness and hygiene of kitchen utensils have always been a major concern. Dishwashers utilize bubbles to improve cleaning performance and reduce consumable usage. However, bubbles require thorough mixing of gas and liquid within the dissolving chamber to achieve the desired effect. When the bubble generator is working, gas flows into the chamber with the liquid and exits from the outlet, reducing the gas content within the generator. This significantly reduces the final bubble effect, affecting the cleaning performance of items and indicating room for improvement. Summary of the Invention

[0034] The following is for reference. Figures 1-2 The bubble generating device 100 according to an embodiment of the present invention is described. By providing a dissolved gas space 12 in the bubble generating module 101, the liquid before entering the bubbler 9 is fully mixed with the gas in the dissolved gas space 12. An outlet 15 and an inlet 14 are provided at the bottom of the dissolved gas space 12, and an inlet channel 4 is provided to extend upward relative to the inlet 14 to communicate with the dissolved gas space 12. This allows the liquid to flow upward into the dissolved gas space 12 and out from the outlet 15 at the bottom. The liquid can form a water seal at the outlet 15, which can trap more gas in the dissolved gas space 12. This facilitates the full mixing of liquid and gas in the dissolved gas space 12, forming a large amount of liquid containing bubbles. This improves the cleaning properties of items and enhances the user experience.

[0035] like Figures 1-2 As shown, a bubble generating device 100 according to an embodiment of the present invention includes: a bubble generating module 101.

[0036] Specifically, the bubble generating module 101 is the main structure of the bubble generating device 100. It can install and fix the structures inside the bubble generating device 100, and can also be used to install the bubble generating device 100 with other structures.

[0037] A dissolved gas space 12 is formed inside the bubble generating module 101. The bubble generating module 101 is provided with a liquid inlet 14, an air inlet 13 and a liquid outlet 15 respectively connected to the dissolved gas space 12. The liquid inlet 14 is connected to the dissolved gas space 12 through the liquid inlet channel 4. The liquid entering through the liquid inlet 14 and the gas entering through the air inlet 13 are suitable to be mixed in the dissolved gas space 12 and then flow to the liquid outlet 15. The liquid outlet 15 is connected to the bubbler 9.

[0038] Specifically, a portion of the structure of the bubble generating module 101 can be configured as a dissolved gas space 12. The dissolved gas space 12 is used to mix liquid and gas. The bubble generating module 101 is provided with a liquid inlet 14 and a liquid outlet 15. The liquid inlet 14 is used to introduce liquid, and the liquid outlet 15 is used to discharge liquid. The bubble generating module 101 is also provided with an air inlet 13 for communicating with the external space to introduce gas. The liquid inlet 14, the air inlet 13, and the liquid outlet 15 are respectively connected to the dissolved gas space 12. The liquid inlet 14 is connected to the dissolved gas space 12 through the liquid inlet channel 4, so that liquid can flow from the liquid inlet 14 through the liquid inlet channel 4 and enter the dissolved gas space 12. In this way, gas outside the bubble generating module 101 can enter the dissolved gas space 12 through the air inlet 13, and liquid can enter the dissolved gas space 12 through the liquid inlet 14 through the liquid inlet 14. The gas and liquid mix in the dissolved gas space 12, and the resulting gas-liquid mixture flows out from the liquid outlet 15, thus achieving pre-mixing of gas and liquid. The air inlet 13 is provided to facilitate the introduction of external gas into the dissolved gas space 12, which can provide more gas for gas-liquid mixing and improve the gas-liquid mixing efficiency.

[0039] Furthermore, the liquid outlet 15 is connected to the aerator 9, which is used to mix water and air to generate bubbles for effective cleaning of the items to be cleaned. By connecting the liquid outlet 15 to the aerator 9, the dissolved air space 12 can be connected to the aerator 9. In this way, the gas-liquid mixture pre-mixed in the dissolved air space 12 can be introduced into the aerator 9 through the liquid outlet 15. In the aerator 9, it is further separated into liquid containing microbubbles. The liquid containing microbubbles can be used for washing the items.

[0040] The liquid inlet 14 and the liquid outlet 15 are both located at the bottom of the dissolved gas space 12, and the liquid inlet channel 4 is constructed to extend upward relative to the liquid inlet 14 to communicate with the dissolved gas space 12.

[0041] In this way, the liquid can flow upward from the bottom inlet 14 through the inlet channel 4 into the dissolved gas space 12, where it mixes with the gas. The mixed liquid and gas in the dissolved gas space 12 then flow out towards the bottom outlet 15. The inlet 14 and outlet 15 are positioned low, allowing the liquid to rise a certain distance before flowing downward. This facilitates the flow of the liquid and gas in the dissolved gas space 12 by gravity, resulting in greater downward kinetic energy for the liquid and thus increasing the flow speed of the liquid.

[0042] Specifically, the inlet 14 and the outlet 15 are spaced apart and located at the bottom of the dissolved gas space 12. The inlet channel 4 is located between the inlet 14 and the dissolved gas space 12, and the inlet channel 4 extends upward. The end of the inlet channel 4 away from the inlet 14 is connected to the dissolved gas space 12, so that the inlet channel 4 and the dissolved gas space 12 can be connected.

[0043] Furthermore, when the bubble generator 100 is working, the air inlet 13 is closed. At this time, due to the strong pressure of the liquid, no more gas can be injected. Therefore, it is necessary to make fuller use of the gas already inside the dissolved air space 12. After the liquid inlet 14 is opened, the liquid flows into the liquid inlet channel 4 and the dissolved air space 12. The gas in the dissolved air space 12 will be discharged from the liquid outlet 15 along with the liquid, resulting in a reduction in the gas content in the dissolved air space 12, which in turn leads to a significant reduction in the final bubble effect. By setting the liquid outlet 15 at the bottom of the dissolved air space 12, when the liquid is initially introduced into the dissolved air space 12, there is less liquid in the dissolved air space 12. The liquid will flow quickly from top to bottom to the liquid outlet 15 by gravity, forming a water seal above the liquid outlet 15. When the liquid quickly forms a water seal on the liquid outlet 15, the possibility of gas being discharged from the dissolved air space 12 can be reduced. Moreover, as the liquid is continuously transported, the remaining liquid mixes with the gas in the dissolved air space 12, and the mixed gas and liquid flow out of the liquid outlet 15.

[0044] According to an embodiment of the present invention, the bubble generating device 100 provides a dissolved gas space 12 in the bubble generating module 101, so that the liquid before entering the bubbler 9 is fully mixed with the gas in the dissolved gas space 12. The outlet 15 and the inlet 14 are located at the bottom of the dissolved gas space 12, and the inlet channel 4 is configured to extend upward relative to the inlet 14 to communicate with the dissolved gas space 12. This allows the liquid to flow upward into the dissolved gas space 12 and out from the outlet 15 at the bottom. A water seal is quickly formed at the outlet 15, which can trap more gas in the dissolved gas space 12. This facilitates the full mixing of the liquid and gas in the dissolved gas space 12, forming a large amount of liquid containing bubbles. This improves the cleaning properties of the items and enhances the user experience.

[0045] In some embodiments, the dissolved gas space 12 includes a first dissolved gas region 123 and a second dissolved gas region 124. The first dissolved gas region 123 is located above the second dissolved gas region 124. The air inlet 13 and the liquid inlet 14 are both connected to the first dissolved gas region 123, and the liquid outlet 15 is located at the bottom of the second dissolved gas region 124.

[0046] Specifically, the dissolved gas space 12 includes two parts, namely a first dissolved gas region 123 and a second dissolved gas region 124. The dissolved gas space 12 extends in the vertical direction, and the first dissolved gas region 123 is connected to the upper side of the second dissolved gas region 124. The liquid inlet 14 and the air inlet 13 can be connected to the first dissolved gas region 123 through different pipes, so that the air inlet 13 and the liquid inlet 14 are respectively connected to the dissolved gas space 12. In this way, both liquid and gas can enter the first dissolved gas region 123. The liquid outlet 15 is connected to the side of the second dissolved gas region 124 away from the first dissolved gas region 123, that is, the liquid outlet 15 is located at the bottom of the second dissolved gas region 124, so that the liquid and gas in the second dissolved gas region 124 are discharged from the liquid outlet 15 at the bottom.

[0047] Furthermore, the gas entering through the air inlet 13 and the liquid entering through the liquid inlet 14 simultaneously enter the first dissolved gas region 123. Some of the liquid flows downwards due to its own gravity and can quickly reach the bottom of the second dissolved gas region 124, reaching the position above the liquid outlet 15, which can form a water seal on the liquid outlet 15. The remaining liquid mixes with the gas in the first dissolved gas region 123 and the second dissolved gas region 124, and the mixed gas and liquid flow out of the liquid outlet 15.

[0048] In some embodiments, the cross-sectional area of ​​the second dissolved gas region 124 is smaller than that of the first dissolved gas region 123. This allows the first dissolved gas region 123 to have a larger cross-sectional area, which can accommodate more gas and liquid and allows most of the liquid and gas to mix within the first dissolved gas region 123, thus improving the mixing of gas and liquid within the dissolved gas space 12. The smaller cross-sectional area of ​​the second dissolved gas region 124 also allows for some mixing of gas and liquid, and the smaller cross-sectional area allows the gas and liquid mixture to accumulate, thereby increasing the flow rate of the gas-liquid mixture and the discharge rate of gas and liquid, thus improving the efficiency of gas-liquid mixture production and the efficiency of cleaning items.

[0049] Furthermore, the second dissolved gas region 124 is located below the first dissolved gas region 123. The cross-sectional area of ​​the second dissolved gas region 124 is smaller than that of the first dissolved gas region 123. The cross-sectional area can be designed to gradually decrease from the first dissolved gas region 123 to the second dissolved gas region 124, meaning the flow path of liquid and gas within the dissolved gas space 12 gradually narrows. This increases the flow velocity of the liquid in the initial stage of water inflow, facilitating its rapid flow to the outlet 15 due to gravity. A water seal is formed at the outlet 15, preventing the liquid from carrying too much gas out of the outlet during the initial water inflow stage. This effectively traps most of the gas within the dissolved gas space 12, improving gas utilization. Simultaneously, the rapid water seal accelerates bubble generation. The small cross-sectional area of ​​the second dissolved gas region 124 also reduces its space requirement, facilitating the installation of other structures.

[0050] In some embodiments, the cross-sectional area of ​​the second dissolved gas region 124 is configured to gradually decrease from top to bottom, and at least a portion of the liquid inlet channel 4 is distributed side by side with the second dissolved gas region 124 in the horizontal direction.

[0051] In other words, the flow path of the liquid in the second dissolved gas region 124 can be gradually reduced from top to bottom. This can guide the flow of liquid and gas. The smaller the cross-sectional area, the faster the liquid and gas flow. Furthermore, the gradual reduction of the cross-sectional area of ​​the second dissolved gas region 124 from top to bottom makes the overall structure smoother and the flow guiding effect better. The gradual reduction of the cross-sectional area of ​​the second dissolved gas region 124 also leaves more space for the arrangement and installation of other structures, making the overall structure more compact.

[0052] Specifically, such as Figure 1 As shown, the cross-sectional area of ​​the second dissolved gas region 124 can be set to gradually decrease from top to bottom towards the liquid outlet 15, which facilitates the guidance of liquid and gas to the liquid outlet 15. It also allows the structure of the second dissolved gas region 124 to tilt in one direction, making the overall structure more compact and occupying less space. At least a portion of the liquid inlet channel 4 is distributed horizontally alongside the second dissolved gas region 124. Thus, as the cross-sectional area of ​​the second dissolved gas region 124 gradually decreases in the vertical direction, space is left horizontally for the distribution of the liquid inlet channel 4, achieving an integrated arrangement of the dissolved gas space 12 and the liquid inlet channel 4, resulting in a more compact and rational structure. The horizontal direction can be left-right, front-back, or a direction intersecting with the front-back direction.

[0053] In some embodiments, the liquid inlet channel 4 is configured to extend obliquely from the upper end to the lower end toward the direction close to the second dissolved gas region 124, and the bubble generating module 101 forms an installation space 16 below the first dissolved gas region 123 that communicates with the liquid inlet channel 4. A flow meter 8 for detecting the flow rate in the liquid inlet channel 4 is installed in the installation space 16.

[0054] Specifically, such as Figure 1 As shown, the liquid inlet channel 4 is constructed to extend obliquely from top to bottom toward the direction close to the second dissolved gas region 124, and the upper end of the liquid inlet channel 4 is close to the first dissolved gas region 123. The lower end of the liquid inlet channel 4 is connected to the liquid inlet 14, which is located at the bottom of the second dissolved gas region 124 of the dissolved gas space 12. This allows the liquid inlet channel 4 to be longer, and the liquid to rise higher along the liquid inlet channel 4, which is conducive to the liquid flowing into the dissolved gas space 12 with greater kinetic energy, thereby increasing the flow speed of the liquid in the dissolved gas space 12 and increasing the total liquid flow rate in the liquid inlet channel 4.

[0055] The liquid inlet channel 4 can be a separate water pipe or conduit arranged within the bubble generating module 101, and can be integrated with the bubble generating module 101 into a single structure. The liquid inlet channel 4 is inclined and has a small pipe size, allowing the bubble generating module 101 to form an installation space 16 below the first dissolved gas region 123. The installation space 16 is connected to the liquid inlet channel 4, allowing liquid in the liquid inlet channel 4 to flow into the installation space 16. A flow meter 8 is installed in the installation space 26 to detect the liquid flow rate of the liquid inlet channel 4. This makes efficient use of the space below the first dissolved gas region 123, resulting in a more compact and rational structural arrangement with a small footprint, facilitating the integration of the bubble generating device 100 with other structures.

[0056] Furthermore, the liquid inlet channel 4 can be configured to extend partially at an angle, or it can be configured to extend entirely along the angled direction. The configuration is varied and can be flexibly selected. In this embodiment, for example... Figure 1 As shown, the middle part of the liquid inlet channel 4 extends at an angle, and the part connected to the liquid inlet 14 extends vertically. The upper part of the liquid inlet channel 4 also extends vertically. The liquid inlet channel 4 is arranged more compactly and occupies less space, which is conducive to the integrated arrangement of the liquid inlet channel 4 and the dissolved gas space 12.

[0057] It should also be noted that the flow meter 8 can measure the fluid flow rate in the pipe by utilizing the fluid motion pattern according to the physical laws of fluids, making it easy to understand the real-time liquid flow rate.

[0058] For example, the flow meter 8 is detachably connected to the liquid inlet channel 4 at the installation space 16. During use, after liquid is introduced into the liquid inlet channel 4, the flow meter 8 can detect the water flow of the liquid inlet channel 4 at the installation space 16. The flow meter 8 can accurately measure the flow rate of the fluid and provide accurate flow data to ensure that the water flow meets the design requirements. It can also monitor the liquid flow rate of the liquid inlet channel 4 in real time and adjust and control the flow rate as needed, which helps to ensure the uniformity and stability of the liquid-gas mixing process.

[0059] In some embodiments, the second dissolved gas region 124 and the installation space 16 are distributed horizontally on both sides of the liquid inlet channel 4.

[0060] Specifically, such as Figure 1 As shown, in the horizontal direction, the second dissolved gas region 124, the liquid inlet channel 4, and the installation space 16 are distributed sequentially, allowing liquid to flow from the liquid inlet channel 4 into the first dissolved gas region 123. After mixing with the gas in the first dissolved gas region 123, a gas-liquid mixture is formed. The gas-liquid mixture flows downward from the second dissolved gas region 124 on one side of the liquid inlet channel 4 to the liquid outlet 15. When the liquid enters the liquid inlet channel 4, a portion of the liquid will enter the installation space 16 on the other side of the liquid inlet channel 4. This is used by the flow meter 8 to detect the flow rate of the liquid in the installation space 16, which in turn can detect the flow rate of the liquid inlet channel 4. In this way, the gas-liquid mixture can be discharged from one side of the liquid inlet channel 4, and the flow rate can be detected on the other side of the liquid inlet channel 4 without affecting each other, and the overall structure has a higher degree of integration.

[0061] Furthermore, the inclined arrangement of the liquid inlet channel 4 makes the structure of the second dissolved gas region 124, the liquid inlet channel 4, and the installation space 16 more compact, and the space occupied by the three in the horizontal direction is the same as the size occupied by the first dissolved gas region 123. This allows the lower area of ​​the first dissolved gas region 123 to facilitate the arrangement of the above-mentioned structures on the bubble generating module 101, resulting in a flat overall structure.

[0062] In some embodiments, a turbulence structure 121 is provided in the first dissolved gas region 123 to turbulently flow the liquid and gas entering the first dissolved gas region 123, thereby changing the flow direction of the gas and liquid, so that the gas and liquid are fully mixed in the first dissolved gas region 123, and the gas-liquid mixture formed flows out from the liquid outlet 15 to achieve pre-mixing of gas and liquid.

[0063] Specifically, such as Figure 1 As shown, the turbulence structure 121 is distributed in the first dissolved gas region 123, which can reflect and impact the liquid and gas multiple times along the flow direction, improve the effect of liquid and gas mixing due to collision, and avoid the phenomenon that the liquid and gas only flow in the first dissolved gas region 123 without mixing.

[0064] Therefore, the turbulence structure 121 can form a non-linear flow path, which extends the flow path of gas and liquid compared to a straight flow path, thereby allowing the gas and liquid to fully mix and form a large amount of liquid containing bubbles, which can improve the cleaning properties of the item and thus improve the user experience. In addition, the turbulence structure 121 can reduce the space occupied by the gas and liquid mixing path. The overall structure is simple, the function is easy to implement, and the cost is low.

[0065] In some embodiments, the turbulence structure 121 includes at least one first turbulence rib 1211 and at least one second turbulence rib 1212, the at least one first turbulence rib 1211 and at least one second turbulence rib 1212 are interspersed, and a turbulence channel 1213 is defined between the at least one first turbulence rib 1211 and the at least one second turbulence rib 1212.

[0066] Specifically, at least one first baffle rib 1211 and at least one second baffle rib 1212 are provided. The first baffle rib 1211 and the second baffle rib 1212 are intersected, meaning they are connected intersectingly. They can be connected perpendicularly or non-perpendicularly. A baffle channel 1213 is defined between at least one first baffle rib 1211 and at least one second baffle rib 1212, allowing gas and liquid to flow along the baffle channel 1213. Through at least one reflection and impact from at least one first baffle rib 1211 and at least one second baffle rib 1212, the gas and liquid are thoroughly mixed, thereby improving the ability of the gas-liquid mixture to clean stains and thus improving the cleaning effect. Furthermore, the baffle channel 1213 connects the inlet end of the dissolved gas space 12 and the outlet 15, allowing the mixed gas-liquid mixture to flow through the baffle channel 1213 to the outlet 15.

[0067] And such as Figure 1 As shown, a first baffle 1211 is provided at the inlet end of the dissolved gas space 12. The first baffle 1211 separates the inlet end of the dissolved gas space 12 from the air inlet 13, which can prevent the gas and liquid entering the dissolved gas space 12 from directly impacting the air inlet 13 and causing the air inlet 13 to fail to seal. This improves the sealing characteristics of the air inlet 13 and also improves the reliability and stability of the water intake process. Furthermore, the first baffle 1211 and the second baffle 1212 can be integrally formed with the bubble generating module 101, or they can be glued or welded to the bubble generating module 101. Its structure is simple, easy to process, and its function is easy to implement.

[0068] The first baffle 1211 and the second baffle 1212 can be one, two, three, four, etc., and the number of the first baffle 1211 and the second baffle 1212 can be the same or different. It is not limited to the embodiment described in this example, and can be selectively set according to the actual space size.

[0069] In some embodiments, the turbulence structure 121 includes a plurality of turbulence ribs, at least one of which is used to guide the liquid to flow away from the outlet 15, and at least another turbulence rib is used to guide the liquid to flow closer to the outlet 15.

[0070] In this way, different flow-deflecting ribs can change the flow direction of gas and liquid, so that some of the liquid and gas will not flow directly to the liquid outlet 15, allowing the liquid and gas to fill the dissolved gas space 12, thereby improving the mixing of liquid and gas.

[0071] Specifically, in this embodiment, there are multiple first turbulence ribs 1211 and multiple second turbulence ribs 1212, which are spaced apart. The multiple first turbulence ribs 1211 are spaced apart along their extension direction, and the multiple second turbulence ribs 1212 are also spaced apart along the extension direction of the first turbulence ribs 1211. In this way, multiple turbulence flow sections 1214 with different extension directions can be formed. This allows at least one turbulence rib to guide the liquid to flow in the corresponding turbulence flow section 1214 toward the direction closer to the liquid outlet 15, that is, this part of the liquid can directly flow out of the liquid outlet 15 along the turbulence flow section 1214. At least another turbulence rib can guide the liquid to flow in the corresponding turbulence flow section 1214 toward the direction away from the liquid outlet 15, that is, this part of the liquid can fill the space of the dissolved gas space 12 away from the liquid outlet 15.

[0072] Therefore, by setting the liquid to flow in the opposite direction within the dissolved gas space 12, while allowing the liquid to fill the dissolved gas space 12 more, the gas that has not participated in the fusion can be squeezed to the top of the dissolved gas space 12, and the gas at the top can continue to flow into the dissolved gas space 12 to continue to participate in the subsequent liquid and gas mixing.

[0073] In some embodiments, the cross-sectional area of ​​the liquid outlet 15 is smaller than the cross-sectional area of ​​the dissolved gas space 12. The large cross-sectional area of ​​the dissolved gas space 12 allows the gas and liquid to be fully mixed within the dissolved gas space 12. The small cross-sectional area of ​​the liquid outlet 15 increases the flow rate of the liquid and gas mixture, thereby increasing the discharge rate of the gas-liquid mixture.

[0074] Therefore, by setting the cross-sectional area of ​​the liquid outlet 15 to be small, the liquid outlet 15 is quickly water-sealed after flowing to the bottom of the dissolved gas space 12, thereby trapping most of the gas inside the dissolved gas space 12, improving gas utilization. Simultaneously, the rapid water-sealing effect accelerates bubble generation and achieves a higher discharge speed of the gas-liquid mixture, thus improving the cleaning efficiency of the items. Furthermore, the small cross-sectional area results in greater resistance to the liquid during outflow, which helps to better retain the dissolved gas in the liquid, enhancing the dissolved gas effect and reducing the liquid flow rate to some extent, thus lowering energy consumption. In addition, the increased flow velocity also increases the kinetic energy of the liquid, which helps to reduce energy consumption in subsequent processing or transportation. Moreover, the small cross-sectional area of ​​the liquid outlet 15 facilitates its size matching with the bubbler 9, enabling a reliable connection between the two and improving the stability of the liquid flow.

[0075] In some embodiments, the bubble generating device 100 further includes a Venturi tube 2, which is provided with an air inlet 21, a liquid inlet 22 and a mixing outlet 23. The air inlet 21 is connected to the air inlet 13, the liquid inlet 22 is connected to the liquid inlet 14 through the liquid inlet channel 4, and the mixing outlet 23 is connected to the dissolved gas space 12.

[0076] Specifically, such as Figure 1 As shown, an air inlet 21 can be provided in the inlet area of ​​the Venturi pipe 2, and the air inlet 21 is connected to the air inlet 13, so that the external space can be connected to the Venturi pipe 2 to realize the flow of gas. A liquid inlet 22 can be provided in the inlet area of ​​the Venturi pipe 2, and the liquid inlet 22 is connected to the liquid inlet 14 through the liquid inlet channel 4, so that the liquid inlet 14, the liquid inlet channel 4 and the Venturi pipe 2 can be connected to realize the flow of liquid. A mixing outlet 23 can be provided in the outlet area of ​​the Venturi pipe 2, and the mixing outlet 23 is connected to the dissolved gas space 12, so that the Venturi pipe 2 and the dissolved gas space 12 can be connected.

[0077] Furthermore, external gas enters the dissolved gas space 12 through the air inlet 13, and the gas enters the Venturi pipe 2 through the air inlet 21. At the same time, the liquid at the liquid inlet 14 enters the Venturi pipe 2 through the liquid inlet channel 4 and the liquid inlet 22. After the gas and liquid are mixed in the Venturi pipe 2, they enter the dissolved gas space 12 through the mixing outlet 23, where the mixing of gas and liquid continues.

[0078] It should be noted that the Venturi pipe 2 has a Venturi structure inside, and the cross-section of the Venturi structure can be set to gradually decrease and then gradually increase from the inlet area to the outlet area of ​​the Venturi pipe 2. This allows a vacuum area to be formed inside the Venturi pipe 2 when the liquid passes through the narrow channel. The water flow can draw in the gas inside the Venturi pipe 2, mixing the liquid and gas for the first time. After mixing, the gas and liquid enter the dissolved gas space 12 for a second mixing, thereby improving the mixing characteristics of the liquid and gas.

[0079] The Venturi pipe 2 can be integrally formed with the bubble generating module 101, or it can be a separate pipe that is detachably connected to the bubble generating module 101.

[0080] In some embodiments, the Venturi conduit 2 is located at the middle of the dissolved gas space 12 in the vertical direction. For example, the Venturi conduit 2 can be located slightly above the middle of the dissolved gas space 12 in the vertical direction, or slightly below the middle of the dissolved gas space 12 in the vertical direction. Since the Venturi conduit 2 is connected to the outlet end of the liquid inlet channel 4, the liquid can enter the Venturi conduit 2 at a higher position, increasing the liquid's rising height. Furthermore, the installation method is diverse and can be flexibly selected according to actual space requirements.

[0081] Specifically, the liquid inlet channel 4 is located upstream of the Venturi pipe 2. The liquid inlet 14 of the liquid inlet channel 4 can be connected to a tap water pipe or to a water tank. The liquid inlet channel 4, the Venturi pipe 2, and the dissolved gas space 12 are connected sequentially along the direction of liquid flow. In this way, tap water or water stored in the water tank can be sent from bottom to top into the Venturi pipe 2 through the liquid inlet channel 4. The liquid and gas are fully mixed in the Venturi pipe 2 and the dissolved gas space 12. The mixed gas-liquid mixture is then introduced into the bubbler 9.

[0082] Thus, through the above settings, water can be supplied to the Venturi pipe 2 in an upward direction and mixed with gas during the downward flow in the top area of ​​the dissolved gas space 12. This increases the flow path of the liquid and provides more liquid that encapsulates the gas, thereby improving the cleaning properties of the items being washed.

[0083] In some embodiments, the bubble generating module 101 also has an air intake channel 3, which is connected between the air intake hole 21 and the air intake port 13.

[0084] Specifically, the air inlet 13 is connected to the dissolved gas space 12, one end of the air inlet channel 3 is connected to the air inlet 13, and the other end is connected to the air inlet 21. In this way, the gas at the air inlet 13 can be introduced into the air inlet 21 through the air inlet channel 3, and the dissolved gas space 12 can be connected to the Venturi pipe 2 through the air inlet channel 3, so that the air in the dissolved gas space 12 can be introduced into the Venturi pipe 2 through the air inlet channel 3, and gas can be introduced into the Venturi pipe 2.

[0085] This configuration allows external air to be directly introduced into the Venturi pipe 2 through the air intake channel 3, and also allows gas in the dissolved gas space 12 to be introduced into the Venturi pipe 2. This improves the air supply mode of the Venturi pipe 2 and allows the remaining gas in the dissolved gas space 12 to be recycled, thereby improving the air utilization rate of the overall system and thus improving the thorough mixing of gas and liquid.

[0086] Furthermore, at least a portion of the intake channel 3 is constructed to extend downwards from the top of the dissolved gas space 12 to connect with the Venturi pipe 2. In other words, the intake pipe 3 connects to the top of the dissolved gas space 12, and the intake channel 13 extends downwards to connect with the intake port 21, thus achieving communication between the intake channel 13 and the Venturi pipe 2. Therefore, un-fused gas at the top of the dissolved gas space 12 can be passed downwards through the intake channel 3 into the Venturi pipe 2, achieving gas recycling. Moreover, the intake channel 3 occupies less space, resulting in a more compact overall structure and higher integration.

[0087] The air intake channel 3 can be integrally formed with the bubble generating module 101, or it can be a separate pipe that is detachably connected to the bubble generating module 101.

[0088] In some embodiments, at least a portion of the air intake channel 3 is configured to extend in the vertical direction and be arranged side by side with the dissolved air space 12 in the horizontal direction.

[0089] Specifically, the top of the air intake channel 3 is connected to the top of the dissolved gas space 12, and at least part of the air intake channel 3 extends downward. Arc-shaped channels can be provided in the top region of the air intake channel 3 and the connection between the air intake channel 3 and the Venturi pipe 2, so that the air intake channel 3 is distributed outside the first dissolved gas region 123 of the dissolved gas space 12, and the air intake channel 3 and the first dissolved gas region 123 are arranged side by side in the horizontal direction. The gas that has not participated in the fusion at the top of the dissolved gas space 12 can be passed downward into the Venturi pipe 2 through the air intake channel 3 to realize the recycling of gas. Moreover, the air intake channel 3 occupies less space, and the overall structure is compact and more integrated.

[0090] Furthermore, the air intake channel 3 is arranged side by side with the first dissolved gas area 123 in the horizontal direction. The air intake channel 3 is a separate channel, which can allow the gas at the top of the first dissolved gas area 123 and the gas entering from the external space to be introduced into the Venturi pipe 2, thereby increasing the air intake volume of the Venturi pipe 2.

[0091] In some embodiments, a first one-way valve 31 is provided in the dissolved gas space 12. The first one-way valve 31 is configured to conduct unidirectionally from the air inlet 13 to the dissolved gas space 12, and the first one-way valve 31 is configured to open under the action of negative pressure in the dissolved gas space 12.

[0092] Specifically, the first one-way valve 31 is used for one-way gas flow, such as... Figure 2 As shown, the first one-way valve 31 is located at the top of the dissolved gas space 12 and at the inlet end of the air inlet channel 3. The first one-way valve 31 is detachably connected to the top of the dissolved gas space 12 and is located near the air inlet 13. When the air inlet channel 3 is under negative pressure, a pressure difference can be formed between the dissolved gas space 12 and the external space, so that the first one-way valve 31 is opened by the pressure difference. In this way, gas can flow unidirectionally from the air inlet 13 to the air inlet 21.

[0093] Furthermore, gas enters through the inlet 13 via the first one-way valve 31, and the gas and liquid enter the dissolved gas space 12. The water inside the dissolved gas space 12 flows downward by gravity. When the pressure inside the dissolved gas space 12 is less than the external pressure, the first one-way valve 31 opens due to the pressure difference. External gas enters the dissolved gas space 12 and the intake channel 3 through the inlet 13 via the first one-way valve 31, thereby supplying gas to the Venturi pipe 2, which enables the next step of gas and liquid mixing.

[0094] Furthermore, when water enters the liquid inlet channel 4 and a negative pressure is formed inside the dissolved gas space 12, a siphon effect is easily formed. At this time, the larger external air pressure will open the first one-way valve 31, and the gas will flow into the dissolved gas space 12 to balance the pressure difference, thereby playing the role of preventing siphoning.

[0095] Therefore, by setting the first one-way valve 31, the gas can flow in one direction and continuously supply gas to the air inlet channel 3, avoiding the gas reverse flow from affecting the mixing of gas and liquid, thereby improving the stability of gas delivery.

[0096] In addition, the first one-way valve 31 can also be configured as an electrically controlled valve. The electrically controlled valve can open and close according to the air pressure in the air intake channel 3. Specifically, the electrically controlled valve opens when a negative pressure is generated in the air intake channel 3; and closes when the air intake channel 3 is under positive pressure or normal pressure. For example, when there is a negative pressure in the dissolved gas space 12 and / or the liquid inlet channel 4, the air intake channel 3 can also be under negative pressure. At this time, gas can enter the air intake channel 3 through the electrically controlled valve and enter the dissolved gas space 12 to achieve water intake anti-siphon; or enter the liquid inlet channel 4 to achieve gas-liquid mixing. In addition, when the air pressure in the air intake channel 3 is the same as the air pressure (i.e., atmospheric pressure) at the air inlet 13, the air pressure in the air intake channel 3 is normal pressure; when the air pressure in the air intake channel 3 is greater than the air pressure at the air inlet 13, the air pressure in the air intake channel 3 is positive pressure.

[0097] In some embodiments, the Venturi tube 2 extends in the vertical direction, and the inlet hole 22 is located at the bottom of the Venturi tube 2 and communicates with the upper end of the inlet channel 4.

[0098] Specifically, such as Figure 1 As shown, the Venturi tube 2 extends in the vertical direction. The bottom of the Venturi tube 2 is provided with a liquid inlet 22. The Venturi tube 2 is located in the middle of the dissolved gas space 12. The length of the Venturi tube 2 is not long, that is, the liquid inlet 22 is located in the middle of the dissolved gas space 12. The lower end of the liquid inlet channel 4 is the liquid inlet 14, and the upper end of the liquid inlet channel 4 is the water outlet, which is connected to the liquid inlet 22, so that the liquid inlet channel 4 can be connected to the bottom of the Venturi tube 2.

[0099] Furthermore, the liquid inlet 22 is located at the bottom of the Venturi pipe 2, allowing the water in the liquid inlet channel 4 to flow in from the bottom of the Venturi pipe 2 and mix with the gas in the air inlet channel 3, so that the initially mixed gas and liquid can flow from bottom to top into the dissolved gas space 12.

[0100] This allows gas and liquid to flow from a lower to a higher position, rising into the dissolved gas space 12 and then flowing down to the liquid outlet 15. The liquid can achieve a water seal effect at the liquid outlet 15 using gravity, thus ensuring that the subsequently flowing liquid and gas are fully mixed in the dissolved gas space 12 to meet the requirements of the setup.

[0101] In some embodiments, the inlet 14 and the outlet 15 are both located at the bottom of the bubble generating module 101, and the inlet 14 and the outlet 15 are spaced apart. In this way, the liquid can flow from the bottom of the bubble generating module 101 upwards into the inlet channel 4, the venturi channel 2 and the dissolved gas space 12 in sequence, and the gas-liquid mixture in the dissolved gas space 12 flows downwards to the bottom of the bubble generating module 101 and flows into the bubbler 9 from the outlet 15, forming an inverted U-shaped flow path. This makes the distribution of multiple channels more compact and occupies less space, improving the overall integration.

[0102] In some embodiments, the bubble generating device 100 further includes a respirator module 102, which is integrated with the bubble generating module 101. An exhaust space 5 is also formed in the respirator module 102. The exhaust space 5 is provided with an exhaust inlet 51 and an exhaust outlet 52. The exhaust inlet 51 and the air inlet 13 are respectively connected to the exhaust space 5.

[0103] Specifically, the respirator module 102 is connected to the bubble generating module 101, which integrates the respirator module 102 and the bubble generating module 101 into a single structure. This allows for the mixing of gas and liquid within the bubble generating module 101 for the equipment's washing function, and also allows for the emission of internal gases within the respirator module 102. This results in a more compact structure and more complete functions.

[0104] The exhaust space 5 of the respirator module 102 is used for venting gas. A portion of the respirator module 102 can be configured as the exhaust space 5. For example... Figure 1 As shown, the exhaust space 5 is provided with an exhaust inlet 51 for discharging gas, and the exhaust space 5 is also provided with an exhaust outlet 52 for communicating with the external space. In this way, the gas entering through the exhaust inlet 51 passes through the exhaust space 5 and is discharged from the respirator module 102 through the exhaust outlet 52.

[0105] Furthermore, after connecting the bubble generator 100 to some cleaning equipment, the bubble generator module 101 generates a large amount of gas-liquid mixture containing gas for cleaning items. During the cleaning process, heated gas is generated in the cleaning space. As the gas increases and the pressure increases, the gas in the cleaning equipment can enter the exhaust space 5 from the exhaust inlet 51 and be discharged from the exhaust outlet 52 of the exhaust space 5. This reduces the pressure during the cleaning process, improves the safety and stability of cleaning items, and has a reasonable and reliable structure.

[0106] Furthermore, the air inlet 13 is connected to the exhaust space 5, so that the gas in the exhaust space 5 can enter the dissolved gas space 12 or the air intake channel 3 through the air inlet 13, thereby providing gas to the Venturi pipe 2 and realizing the recycling of gas in the exhaust space 5, thus improving the gas utilization rate.

[0107] In some embodiments, the air inlet 13 is selectively connected to the exhaust space 5, that is, the air inlet 13 may be connected to the exhaust space 5, or the air inlet 13 may not be connected to the exhaust space 5. In this embodiment, the first one-way valve 31 can be selectively opened or closed to switch the connection between the air inlet 13 and the exhaust space 5. When the air inlet 13 is connected to the exhaust space 5, external gas or gas in the exhaust space 5 can enter the air inlet 13, that is, gas can be supplied to the dissolved gas space 12 and the air intake channel 3. When the air inlet 13 is not connected to the exhaust space 5, gas will not enter the air inlet 13, that is, gas will not be supplied to the dissolved gas space 12 and the air intake channel 3.

[0108] Therefore, by selectively connecting the air inlet 13 and the exhaust space 5, it is possible to avoid continuously supplying air to the dissolved gas space 12, and to supply air to the dissolved gas space 12 in a timely manner, making the operation of the bubble generating module 101 more flexible and reliable.

[0109] In some embodiments, a drainage channel 6 is also formed within the respirator module 102. The drainage channel 6 has a drainage inlet 61 and a drainage outlet 62, and the drainage channel 6 is connected to the exhaust space 5.

[0110] Specifically, the drainage channel 6 is used to discharge liquid, and another part of the structure of the respirator module 102 can be configured as the drainage channel 6, wherein, for example... Figure 1 As shown, the drainage channel 6 is provided with a drainage inlet 61 that connects to an external water system. The drainage inlet 61 is used to discharge liquid, and the drainage channel 6 is also provided with a drainage outlet 62. The drainage channel 6 can be connected to the external water system through the drainage outlet 62. In this way, when the washing is finished, the washed wastewater enters the drainage channel 6 from the drainage inlet 61, and then flows through the drain pipe to the outside of the breather module 102, realizing the discharge of wastewater. The drainage channel 6 can serve as a central drainage pipe, and the drainage channel 6 is also connected to a drainage pump for pumping liquid flow.

[0111] Furthermore, the drainage channel 6 is connected to the exhaust space 5, which allows the gas in the exhaust space 5 to enter the drainage channel 6, replenishing the gas pressure in the drainage channel 6 to balance the pressure in the drainage channel 6 and prevent backflow in the drainage channel 6. This configuration also enables the gas in the exhaust space 5 to be recycled, improving the gas utilization rate.

[0112] The drainage inlet 61 and drainage outlet 62 can be located at the bottom of the respirator module 102 and are spaced apart, thus forming an inverted U-shaped liquid flow path. This makes the overall structure of the channel more compact and occupies less space, improving the overall integration.

[0113] The respirator module 102 also has a connection channel 7, which has a connection inlet 71 and a connection outlet 72. The connection inlet 71 is connected to the exhaust space 5, and the connection outlet 72 is connected to the drainage channel 6.

[0114] Specifically, the connecting channel 7 is located between the exhaust space 5 and the drainage channel 6. The connecting channel 7 is connected to the exhaust space 5 through the connecting inlet 71 and to the drainage channel 6 through the connecting outlet 72. The connecting channel 7 is located on the side of the exhaust space 5 away from the dissolved gas space 12. The connecting channel 7 can be set to extend vertically, so that the gas in the exhaust space 5 can be introduced into the drainage channel 6 through the connecting channel 7.

[0115] Furthermore, during the washing process, and when the drain channel 6 drains water, a negative pressure state is formed inside the drain channel 6, which can easily create a siphon effect, causing the liquid discharged from the drain channel 6 to flow back. In this embodiment, by quickly introducing gas into the drain channel 6 through the connecting channel 7, the gas pressure inside the drain channel 6 can be replenished, thereby preventing the backflow of water during the drainage process.

[0116] The exhaust outlet 52 of the exhaust space 5 is connected to the external space. That is, when the exhaust space 5 is not venting, or when the pressure of the exhaust space 5 is lower than that of the external space, external gas can enter the exhaust space 5 through the exhaust outlet 52, and the gas entering can flow to the connecting channel 7, and can also supply gas to the connecting channel 7.

[0117] Therefore, through the above-mentioned arrangement, the gas in the external space or the exhaust space 5 can be used to enter the drainage channel 6, which can effectively replenish the gas pressure in the drainage channel 6 to balance the pressure of the drainage channel 6, thereby playing the role of preventing siphoning. Its structure is simple and its use effect is good.

[0118] The connecting channel 7 can be integrally formed with the respirator module 102, or it can be a separate pipe that is detachably connected to the respirator module 102.

[0119] In some embodiments, the connection inlet 71 is provided with a second one-way valve 73, which is configured to allow one-way flow from the exhaust space 5 to the connection channel 7.

[0120] Specifically, the second one-way valve 73 is used for one-way gas flow, such as... Figure 1 As shown, the second one-way valve 73 is located at the connection inlet 71 of the connection channel 7. The second one-way valve 73 is detachably connected to the top of the connection channel 7, and the second one-way valve 73 is configured to open under the action of negative pressure at the connection inlet 71. That is, when a pressure difference is formed between the inside of the connection channel 7 and the outside space, the second one-way valve 73 is opened by the pressure difference, so that gas can flow unidirectionally from the exhaust inlet 51 to the connection inlet 71.

[0121] Furthermore, during the washing process, and when encountering the drain siphon effect, the larger external air pressure will open the second one-way valve 73, and the gas will enter the exhaust space 5 from the exhaust outlet 52 and enter the connecting channel 7 through the second one-way valve 73, so as to balance the air pressure inside the drain channel 6, thereby playing the role of preventing siphon.

[0122] Therefore, by setting a second one-way valve 73, the gas can flow in one direction and balance the air pressure between the drain channel 6 and the external space, thereby improving the stability of liquid discharge.

[0123] The present invention also proposes a washing device.

[0124] According to an embodiment of the present invention, a washing device includes: a main body and a bubble generating device 100 of any of the above embodiments, a washing space is formed in the main body, a foamer 9 is connected to the washing space, and a bubble generating module 101 is integrated into the main body.

[0125] Specifically, the main body 1 is the primary structure of the washing equipment, supporting the internal structures and accommodating various installations. A washing space is formed within the main body to perform the washing function. This washing equipment can be a dishwasher, washing machine, or similar appliance to provide different cleaning functions. The washing space can be an open cavity structure for placing items to be washed, and can be open upwards or forwards for easy operation. Furthermore, an aerator 9 is connected to the washing space. The aerator 9 mixes water and air to generate bubbles, effectively cleaning the items. Specifically, the liquid containing tiny bubbles produced by the aerator 9 is introduced into the washing space to clean the items within.

[0126] Furthermore, the bubble generating module 101 is integrated into the main body of the device, and the aerator 9 is connected to the dissolved air space 12. The gas and liquid can be mixed in the dissolved air space 12, and the resulting gas-liquid mixture can then be used by the aerator 9 to produce more liquid containing bubbles for cleaning, thereby increasing the contact area between the water flow and the rinsed items, improving the washing effect, saving water, and enhancing the user experience.

[0127] The bubble generating module 101 can be detachably connected to the main body of the equipment by bolts, or by snap-fit ​​or plug-in connection, so that the bubble generating device 100 can be disassembled and installed separately from the main body of the equipment, which facilitates subsequent maintenance and inspection. In addition, the bubble generating module 101 can be integrally formed with the main body of the equipment, reducing the connection steps between the two and reducing installation costs.

[0128] Furthermore, by setting a dissolved gas space 12 in the bubble generating module 101, the liquid before entering the bubbler 9 is fully mixed with the gas in the dissolved gas space 12. The liquid outlet 15 and the liquid inlet 14 are located at the bottom of the dissolved gas space 12, and the liquid inlet channel 4 is configured to extend upward relative to the liquid inlet 14 to communicate with the dissolved gas space 12. This allows the liquid to flow upward into the dissolved gas space 12 and out from the liquid outlet 15 at the bottom. A water seal is quickly formed at the liquid outlet 15, which can lock more gas in the dissolved gas space 12, which is conducive to the full mixing of liquid and gas in the dissolved gas space 12, thereby improving the cleaning properties of the items.
