When the mixed water supplied to the dissolution space (A) of the dissolution means (4) through the pump means (3) is supplied through the transfer pressure of the raw water, through the dissolution pressure formed inside the dissolution space (A) Nanobubbles are generated, and the generated nanobubble water is supplied to the user through the supply pipe 200.

In the above, it is preferable that the pump means 3 be appropriately applied according to the user's selection in a structure using conventionally known technology.

In the above, the dissolution space (A) of the dissolution means (4) may be formed in the 'interspace' where the supply port and the drain port are respectively spatially connected.

That is, the dissolution space (A), the pump room, and the supply pipe 200 are spatially connected through the supply port and the drain port.

Accordingly, after the mixed water is nanobubbled through the supply port outside the dissolving means 4, it is applied as washing water and sprayed into the inside of the washing chamber 311 via the drain hole and the supply pipe 200. may be put to use.

That is, the nanobubble water continuously generated in the dissolving means 4 through continuous operation of the pump means 3 is sprayed and supplied to the washing chamber 311 through the supply pipe 200.

In addition, under the control of the control means 51, the nanobubble water supplied from the dissolution means 4 to the supply pipe 200 is recovered to the inlet through the circulation pipe 220, and the pump chamber and the dissolution space ( A) forms a circular path that circulates through each of them sequentially.

Accordingly, the dissolution quality of nanobubbles in nanobubble water can be improved, thereby improving the quality of use of nanobubble water.

Meanwhile, the supply pipe 200 is generally provided with a supply opening/closing valve 330 that is driven according to the driving data set in the control means 51, and the supply pipe 200 is operated through the supply opening/closing valve 330. In a state where the supply of washing water is blocked by closing, the wastewater discharge step of discharging the wastewater from the point of use to the outside can be performed.

That is, when the wastewater discharge step at the point of use (for example, the dishwasher 300) progresses, the supply of fresh water to the supply pipe 200 may be stopped.

In the nanobubble device 1 according to this embodiment configured as described above, the control means 51 controls the open/closed state of the supply pipe 200 of the dishwasher 300 (open/closed state of the supply on/off valve 330). It is designed to control the opening and closing operation of the recovery valve 61 by calculating based on the supply opening and closing data obtained by detecting or calculating.

That is, when the supply of nanobubble water to the supply pipe 200 is stopped as described above, the recovery is performed based on the supply open/close data for the supply open/close valve 330 transmitted to the control means 51. By opening the valve 61, the nanobubble water drained from the dissolving means 4 is returned to the inlet to form the above-described circulation path.

In addition, when it is desired to re-supply washing water by opening the supply pipe 200 through the supply opening/closing valve 330 according to the drive data normally set at the place of use (dishwasher 300), the guard Based on the supply opening/closing data transmitted to the means 51, the recovery valve 61 is closed so that the nanobubble water drained from the dissolution means 4 is supplied to the supply pipe, and the above-described circulation path is released. .

Accordingly, nanobubble water can be stably supplied in conjunction with the user (dishwasher 300) without repeatedly stopping and restarting the pump means 3.

In the nanobubble device 1 according to the present embodiment configured as described above, the inlet pipe 230, which is connected to the inlet of the pump means 3 and through which water flows, is driven through the control of the control means. An air supply means 400 configured to forcibly supply air may be connected to the pipe.

That is, when the vacuum pressure is formed by the moving pressure of the water when the water flows into the inlet pipe 230 according to the driving of the pump means (3), the air supply means is controlled by the control means (3). (400) is driven so that air is forcibly supplied and mixed with water to form mixed water.

In addition, when the operation of the pump means (3) is stopped, the supply of water from the inlet pipe (230) is stopped and the vacuum pressure is released in the water movement path, and at this time, the air supply means (400) is driven. This can be stopped.

Meanwhile, the air supply means 400 may be provided with a one-way check valve to close the pipe to prevent leakage of the mixed water flowing back when the supply of water from the inlet pipe 230 is stopped.

Accordingly, a stable supply of air is naturally achieved, and leakage of water or mixed water from the air supply means 400 to the outside can be prevented, thereby realizing stability.

In the above, the air supply means 400 may be operated at the opening time of the supply open/close valve 330 to supply air by calculating through the control means 3 based on the supply open/close data.

That is, when it is returned to the inlet through the circulation pipe 220 and forms a circulation path that sequentially circulates through the pump chamber and the dissolution space (A), the supply of air is blocked, causing supersaturation of the air in the water. This can prevent the condition from forming.

Accordingly, the pump means 3 can be driven more stably.

The nanobubble device (1) according to the present embodiment configured as described above has a storage space (B) formed with an inlet through which water is supplied and an outlet connected to the inlet of the pump means (3) to discharge and supply water. It further includes a storage tank (7) provided.

Accordingly, manufacturing can be easily performed and it can be provided economically.

In addition, structural miniaturization of the storage body 71 is possible, and nanobubbles can be generated using tap water as raw water in general homes, thereby improving usability.

Meanwhile, in the connector 240 above. A diffusion nozzle 72 may be provided to spray tap water while diffusing it into the storage space (B).

That is, the tap water supplied bound to the inlet is ejected into the storage space (B) through the diffusion nozzle 72 and diffuses, colliding with the air remaining in the storage space (B) and becoming fine particles.

Accordingly, while the tap water is being ejected into the storage space (B), it is reduced to fine particles and nanobubbling in the storage space (B) is promoted.

In the above-mentioned diffusion nozzle 72, while the tap water supplied through the connection pipe 240 is passing through the compressed narrow inner diameter, the compressed state is released and the tap water is ejected while passing through the wide inner diameter. It can be made of a configuration and structure that can be appropriately applied according to the user's choice among conventionally known technologies.

Accordingly, the air consumed due to the dissolution of air in the storage space (B) is replenished, and nanobubbles can be efficiently generated.

Among conventionally known technologies, the one-way air supply member 410 is a 'one-way check valve' that supplies external air to the storage space (B) but closes the discharge from the storage space (B) to the outside. 'It can be structured, and it is desirable to apply it appropriately according to the user's choice.

In the nanobubble device (1) according to the present embodiment configured as described above, one end of the circulation pipe (220) is spatially connected to the storage space of the storage tank (7), so that water flows into the storage space (B). The circulation path may be formed to sequentially pass through the pump chamber, the dissolution space (A), and the circulation pipe 220, respectively.

That is, when the supply of nanobubble water to the point of use is stopped, the water stored in the storage tank (7) flows through the storage space (B), the pump room, the dissolution space (A), and the circulation pipe (220). Nanobubble hydration continues as it circulates through each of the circulation paths sequentially, so that high quality nanobubble water is supplied when nanobubble water is resupplied to the point of use in a state where nanobubble quality is maximized. It can be.
