Fig. 1 is a schematic view of a bubble generation device 1 according to an embodiment of the present invention, which includes a dissolved air chamber 12, a bubbler 11, a drain valve, a bypass 13, and a switching unit 14. The upstream of the switching unit 14 is connected to a fluid pipeline with pressure such as tap water, the outlet of the bubbler 11 can be used as a bubble water outlet and a drainage air inlet, and the outlet of the bypass 13 can be used as a waste water outlet.

The bubble generation device 1 has the following principle: in the air dissolving stage, the air dissolving cavity 12 is filled with air, the liquid discharge valve is closed, and the switching unit 14 is communicated with the air dissolving cavity 12 and is disconnected with other paths. Because the bubbler 11 has throttling function, the water inlet speed of the air dissolving cavity 12 is higher than the water outlet speed, and the pressure of the air dissolving cavity 12 is continuously increased until the pressure is approximately equal to the total pressure of tap water. As the pressure increases, the gas in the gas dissolving chamber 12 is continuously dissolved in the water (the higher the pressure, the higher the dissolution rate of the gas). When the gas solution flows to the bubbler 11, the flow cross-sectional area is continuously reduced, the flow rate is increased, the pressure is reduced, and the gas is continuously separated out in a cavitation mode to generate a large amount of micro-bubbles in the throttling process. The micro bubble water is directly discharged into the inner container assembly 20 for washing. As the gas in the gas dissolving chamber 12 is continuously dissolved in water, the gas in the gas dissolving chamber 12 is continuously reduced. Therefore, after a certain period of time, drainage is required. During drainage, the switching unit 14 is communicated with the bypass 13 and disconnected from other paths, and the drain valve is opened. At this time, the tap water flows to the bypass 13 through the selector valve, and forms a main water passage. In the throat 132 of the bypass 13, the flow cross-sectional area is reduced, the flow velocity is increased, the pressure is reduced, a low-pressure area is generated, and water in the dissolved air cavity is sucked out. At this point, the bubbler 11 line acts as an air intake line, drawing air from the bladder assembly 20 into the gas-dissolving chamber 12 and refilling it.

Wherein, the gas medium in the utility model is not only air, and the liquid medium is not only water, and the above-mentioned is only for the convenience of explanation.

The general bypass 13 is constructed as shown in fig. 4 and 5. The horizontal direction is a main flow channel, and the vertical direction is a low-pressure suction inlet.

Fig. 2 shows a drainage water path structure of an embodiment of a dishwasher water inlet system with parallel micro-bubble modules, which includes a liquid inlet valve 15, a breather 22, a water softener 21, a bubble generation device 1, a liner assembly 20, a washing pump 40, a drainage pump 31, a drainage valve 32, a flow meter 17, and a switching unit 14. The bubble generation device 1 comprises a dissolved air cavity 12, a bubbler 11, a drain valve and a bypass 13.

The dishwasher is supplied with water through two parallel water paths. When clean water is needed, the reversing valve is switched to the water paths of the breather 22 and the water softener 21, and water is fed in a traditional mode. When micro bubble water is needed, the reversing valve is switched to the micro bubble module, the dissolved air cavity is pressurized through the water pressure of tap water, the dissolution rate of air in water is increased, and then throttling cavitation is carried out through the bubbler 11 to generate micro bubbles.

This no pump booster-type microbubble generating device 1 principle: in the gas dissolving stage, the gas dissolving cavity 12 is filled with gas, the liquid discharge valve is closed, the liquid inlet valve 15 is opened, and the switching unit 14 enables the liquid inlet valve 15 to be communicated with the gas dissolving cavity 12 and disconnected with other paths. Because the bubbler 11 has throttling function, the water inlet speed of the air dissolving cavity 12 is higher than the water outlet speed, and the pressure of the air dissolving cavity 12 is continuously increased until the pressure is approximately equal to the total pressure of tap water. As the pressure increases, the gas in the gas dissolving chamber 12 is continuously dissolved in the water (the higher the pressure, the higher the dissolution rate of the gas). When the gas solution flows to the bubbler 11, the flow cross-sectional area is continuously reduced, the flow rate is increased, the pressure is reduced, and the gas is continuously separated out in a cavitation mode to generate a large amount of micro-bubbles in the throttling process. The micro bubble water is directly discharged into the inner container assembly 20 for washing. As the gas in the gas dissolving chamber 12 is continuously dissolved in water, the gas in the gas dissolving chamber 12 is continuously reduced. Therefore, after a certain period of time, drainage is required. During water drainage, the liquid inlet valve 15 is opened, the switching unit 14 enables the liquid inlet valve 15 to be communicated with the bypass 13 and disconnected with other paths, and the liquid discharge valve is opened. At this time, the tap water flows to the bypass 13 through the inlet valve 15 to form a main water passage. In the throat 132 of the bypass 13, the flow cross-sectional area is continuously reduced, the flow velocity is increased, the pressure is reduced, a low-pressure area is generated, and water in the dissolved air cavity is sucked out. At this point, the bubbler 11 line acts as an air intake line, drawing air from the bladder assembly 20 into the gas-dissolving chamber 12 and refilling it.

The microbubble generator 1 can be applied to various fields, not only a dishwasher.

Fig. 3 shows a drainage water path structure of an embodiment of a water inlet system of a dishwasher with series-connected micro-bubble modules, which comprises a liquid inlet valve 15, a breather 22, a water softener 21, a bubble generating device 1, a liner assembly 20, a washing pump 40, a drainage pump 31, a drainage valve 32 and a flow meter 17. The micro-bubble module comprises a dissolved air cavity 12, a bubbler 11, a liquid discharge valve, a bypass 13 and a switching unit 14.

The supercharged micro-bubble generating device 1 is connected with the respirator 22 and the water softener 21 in series to form a water inlet system. Wherein the sequence of the respirator 22, the water softener 21 and the bubble generating device 1 is changed, all of which are within the protection scope of the present patent. The dissolved air cavity is pressurized through the water pressure of tap water, the dissolution rate of air in water is increased, and then throttling cavitation is carried out through the bubbler 11 to generate micro bubbles.

This no pump booster-type microbubble generating device 1 principle: in the gas dissolving stage, the gas dissolving cavity 12 is filled with gas, the liquid discharge valve is closed, the liquid inlet valve 15 is opened, and the switching unit 14 enables the liquid inlet valve 15 to be communicated with the gas dissolving cavity 12 and disconnected with other paths. Because the bubbler 11 has throttling function, the water inlet speed of the air dissolving cavity 12 is higher than the water outlet speed, and the pressure of the air dissolving cavity 12 is continuously increased until the pressure is approximately equal to the total pressure of tap water. As the pressure increases, the gas in the gas dissolving chamber 12 is continuously dissolved in the water (the higher the pressure, the higher the dissolution rate of the gas). When the gas solution flows to the bubbler 11, the flow cross-sectional area is continuously reduced, the flow rate is increased, the pressure is reduced, and the gas is continuously separated out in a cavitation mode to generate a large amount of micro-bubbles in the throttling process. The micro bubble water is directly discharged into the inner container assembly 20 for washing. As the gas in the gas dissolving chamber 12 is continuously dissolved in water, the gas in the gas dissolving chamber 12 is continuously reduced. Therefore, after a certain period of time, drainage is required. During water drainage, the liquid inlet valve 15 is opened, the switching unit 14 enables the liquid inlet valve 15 to be communicated with the bypass 13 and disconnected with other paths, and the liquid discharge valve is opened. At this time, the tap water flows into the bypass 13 through the inlet valve 15, forming a main water passage. In the throat 132 of the bypass 13, the flow cross-sectional area is continuously reduced, the flow velocity is increased, the pressure is reduced, a low-pressure area is generated, and water in the dissolved air cavity is sucked out. At this point, the bubbler 11 line acts as an air intake line, drawing air from the bladder assembly 20 into the gas-dissolving chamber 12 and refilling it.

The microbubble generator 1 can be applied to various fields, not only a dishwasher.

Taking 300mm ^3 dissolved air cavity and 0.2MPa main flow pressure as an example, the drainage speed is 37s, and the gravity drainage time under the same condition is about 1min30 s. The bypass 13 is a structural component, and has high reliability and low cost.
