That is, the washing pump 3 pumps the liquid to the bubbler 26, generates bubbles in the bubbler 26, and then sends the bubble-generated liquid to the bladder assembly 1 or the washing pump 3.

More gas is dissolved in the liquid passing through the gas dissolving cavity 21, the liquid outlet of the gas dissolving cavity 21 is connected with the inlet of the bubbler 26, and when the liquid dissolved with more gas enters the bubbler 26, more bubbles can be generated through the bubbler 26.

Specifically, in the operation process of the washing device 100, the washing pump 3 fills the gas dissolving cavity 21 with liquid, and due to the air resistance of the bubbler 26, the pressure in the gas dissolving cavity 21 is increased, so that the gas dissolving rate of the liquid is increased, and the gas dissolved in the liquid is effectively increased.

When the liquid outlet of the gas chamber 21 is connected to the washing pump 3, a part of the gas in the washing pump 3 can flow back into the gas chamber 21 through the liquid outlet, and the liquid can be sent to the inner container assembly 1 through the washing pump 3.

The booster-type micro-bubble generating device 2 can be effectively embedded into the dish-washing machine, and high-concentration micro-nano bubble water is generated for washing. The bubble has small diameter and can be preserved for a long time. By generating microbubbles by pump bypass circulation, the effect on the main flow pressure can be reduced by controlling the bypass flow. Micro-nano bubble water can be generated in a circulating manner in the washing process.

Additionally, the present invention provides a centralized and specific implementation.

As shown in fig. 1, the washing apparatus 100 according to an embodiment of the present invention includes a drain valve 5, a drain pump 6, a washing pump 3, a bubble generating device 2, a bladder assembly 1, and a second switch valve 43. The air bubble generating device 2 comprises an air pump 22, a vent valve 23, a gas dissolving cavity 21 and a bubbler 26.

The inlet and the outlet of the bubble generating device 2 are respectively connected with the inlet and the outlet of the washing pump 3 to form a bypass circulating system, and the bypass is connected with a washing circulating water path (namely a pipeline which is sequentially connected with the outlet of the washing pump 3, the inner container assembly 1 and the inlet of the washing pump 3) in parallel. On the premise of not changing the design idea, the increase or decrease of connecting pieces such as valves and the like is within the protection scope of the patent. The dissolved air cavity 21 is pressurized by the water pressure after being pumped by the washing pump 3, the dissolution rate of the gas in the water is increased, and then throttling cavitation is carried out by the bubbler 26 to generate micro bubbles. Since the bubbler 26 is connected to the inlet of the washing pump 3, the throttling cavitation effect of the bubbler 26 is enhanced by the low pressure before the pump.

The bypass flow is controlled by a second on/off valve 43, and when high pressure water flush is required, the second on/off valve 43 is closed. The second on-off valve 43 is opened when micro-bubble water is required.

Principle of the bubble generation device 2:

in the air dissolving stage, the air dissolving cavity 21 is filled with air, and the vent valve 23 is closed. Because the bubbler 26 has throttling function, the water inlet speed of the air dissolving cavity 21 is higher than the water outlet speed, and the pressure of the air dissolving cavity 21 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 21 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 26, 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 enters the inner container assembly after passing through the water pump again. As the gas in the gas-dissolving chamber 21 is continuously dissolved in the water, the gas in the gas-dissolving chamber 21 is continuously reduced. Therefore, after a certain period of time, drainage is required. When the water is drained, the vent valve 23 is opened, the vent valve 23 is positioned at the upper part of the air dissolving cavity 21, and the water flows back to the inner container through the washing pump 3 and the bubbler 26 by being pressurized by the air pump 22. Gas is admitted through the vent valve 23 to refill the gas-dissolving chamber 21.

The gas medium is not only air, but the liquid medium is not only water, and the above is only for convenience of description.

As shown in fig. 2, the washing apparatus 100 according to an embodiment of the present invention includes a drain valve 5, a drain pump 6, a washing pump 3, a bubbler 26, a bladder assembly 1, and a second switching valve 43.

The inlet and outlet of the bubbler 26 are connected with the inlet and outlet of the water pump to form a bypass flow path, the bypass flow is controlled by the second switch valve 43, and when high-pressure water flow is needed for flushing, the second switch valve 43 is closed. Open when micro-bubble water is required.

The bubbler 26 forms a bypass circulation system with the washing pump 3, and the bypass is connected in parallel with the washing circulation water path (i.e. the pipeline connecting the outlet of the washing pump 3, the liner assembly 1 and the inlet of the washing pump 3 in sequence). On the premise of not changing the design idea, the increase or decrease of connecting pieces such as valves and the like is within the protection scope of the patent.

Throttling cavitation is performed by the bubbler 26 to precipitate dissolved gases in the water. In the throttling process, the flow cross section area is continuously reduced, the flow velocity is increased, the pressure is reduced, the gas is continuously separated out in a cavitation mode, and a large number of micro bubbles are generated. Since the bubbler 26 is connected to the inlet of the washing pump 3, the throttling cavitation effect of the bubbler 26 is enhanced by the low pressure before the pump. Since the dissolved air chamber 21 is not provided, the microbubble concentration of this scheme is lower than that of the scheme of fig. 1.

As shown in fig. 3, the washing apparatus 100 according to an embodiment of the present invention includes a drain valve 5, a drain pump 6, a washing pump 3, a bubble generating device 2, a bladder assembly 1, and a second switching unit 42. The air bubble generating device 2 comprises an air pump 22, a vent valve 23, a gas dissolving cavity 21 and a bubbler 26.

The bubble generating device 2, the washing pump 3, the second switching unit 42 and the liner assembly 1 form a micro-bubble generating water path system. On the premise of not changing the design idea, the increase or decrease of connecting pieces such as valves and the like is within the protection scope of the patent. The dissolved air cavity 21 is pressurized by the water pressure after being pumped by the washing pump 3, the dissolution rate of the gas in the water is increased, and then throttling cavitation is carried out by the bubbler 26 to generate micro bubbles.

The washing water path and the micro-bubble generation water path are controlled by the second switching unit 42, when high-pressure water flow is needed for washing, the second switching unit 42 is communicated with the inner container spray arm, and when micro-bubble water is needed, the second switching unit 42 is communicated with the micro-bubble generation device 2. When the bubble generating means 2 is operated, the wash pump 3 supplies power only to the microbubble generating means 2.

Principle of the supercharged microbubble generation device 2: in the air dissolving stage, the air dissolving cavity 21 is filled with air, and the vent valve 23 is closed. Because the bubbler 26 has throttling function, the water inlet speed of the air dissolving cavity 21 is higher than the water outlet speed, and the pressure of the air dissolving cavity 21 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 21 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 26, 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 enters the inner container assembly after passing through the water pump again. As the gas in the gas-dissolving chamber 21 is continuously dissolved in the water, the gas in the gas-dissolving chamber 21 is continuously reduced. Therefore, after a certain period of time, drainage is required. When the water is drained, the vent valve 23 is opened, the vent valve 23 is positioned at the upper part of the air dissolving cavity 21, and the water flows back to the inner container through the washing pump 3 and the bubbler 26 by being pressurized by the air pump 22. Gas is admitted through the vent valve 23 to refill the gas-dissolving chamber 21.

As shown in fig. 4, the washing apparatus 100 according to an embodiment of the present invention includes a drain valve 5, a drain pump 6, a washing pump 3, a bubble generating device 2, a bladder assembly 1, and a first switching unit 41. The bubble generation device 2 includes a dissolved air chamber 21, a bubbler 26, a first on-off valve 25, and a bypass 24.

The bubble generating device 2, the washing pump 3, the first switching unit 41 and the inner container assembly 1 form a micro-bubble generating water path system. On the premise of not changing the design idea, the increase or decrease of connecting pieces such as valves and the like is within the protection scope of the patent. The dissolved air cavity 21 is pressurized by the water pressure after being pumped by the washing pump 3, the dissolution rate of the gas in the water is increased, and then throttling cavitation is carried out by the bubbler 26 to generate micro bubbles.

The washing water path, the micro-bubble generation water path and the bypass 24 water discharge water path are controlled by the first switching unit 41, and when high-pressure water flow flushing is required, the first switching unit 41 is communicated with a liner spray arm (not shown); when micro bubble water is needed, the first switching unit 41 is communicated with the dissolved air cavity 21; when the air-dissolving chamber 21 needs to be drained, the first switching unit 41 communicates with a bypass 24 (e.g., a venturi tube, a jet pipe, etc.). The washing pump 3 only supplies energy to the bubble generating means 2 when the bubble generating means 2 is operated.

Principle of the bubble generation device 2: in the air dissolving stage, the air dissolving cavity 21 is filled with air, and the vent valve 23 is closed. Because the bubbler 26 has throttling function, the water inlet speed of the air dissolving cavity 21 is higher than the water outlet speed, and the pressure of the air dissolving cavity 21 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 21 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 26, 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 enters the inner container assembly after passing through the water pump again. As the gas in the gas-dissolving chamber 21 is continuously dissolved in the water, the gas in the gas-dissolving chamber 21 is continuously reduced. Therefore, after a certain period of time, drainage is required. When the water is discharged, the first switching unit 41 causes the washing pump 3 to communicate with the bypass 24 and to be disconnected from the other paths, and the first on-off valve 25 is opened. At this time, the water flows to the bypass 24 by the washing pump 3, forming a main water passage. At the throat 242 of the bypass 24, the flow cross-sectional area is continuously reduced, the flow velocity is increased, the pressure is reduced, a low-pressure area is generated, and the water in the gas-dissolving chamber 21 is sucked out. At this point, the bubbler 26 line acts as an air intake line, drawing air from the bladder assembly 1 into the gas-dissolving chamber 21 and refilling it.

As shown in fig. 5, the washing apparatus 100 according to an embodiment of the present invention includes a drain valve 5, a drain pump 6, a washing pump 3, a bubbler 26, a bladder assembly 1, and a second switching unit 42. This solution is a simplified version of the solution of fig. 3, 4. A proportion of the gas has been dissolved in the tap water.
