  However, since an expensive vacuum pump is required, the cost is increased, and the vacuum pump may be difficult to install in a small space, and the durability may deteriorate due to a failure of the vacuum pump. there were.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an oxygen-enriched air introduction device that does not require a vacuum pump, is inexpensive, can be installed in a small space, and has improved durability. It is what.

  In order to solve the above problems, the present invention passes an oxygen-enriched membrane, a ventilation fan that ventilates the surface air of the oxygen-enriched membrane, and a high-concentration oxygen-enriched air produced by the oxygen-enriched membrane. In the oxygen-enriched air introduction device comprising an introduction pipe to be introduced into the water pipe, a high pressure generated in the oxygen-enriched film is produced by causing a negative pressure generated in the water flow of the water pipe to act on the oxygen-rich film from the introduction pipe. The present invention provides an oxygen-enriched air introduction device characterized in that oxygen-enriched air having a concentration is introduced from an introduction pipe into a water pipe.

  As in claim 2, it is preferable to connect a water pump or a water pipe to the water pipe.

  According to a third aspect of the present invention, it is preferable to provide an introduction port of the introduction pipe in the water pipe on the suction side of the water pump.

  As in claim 4, it is preferable to provide a water flow resistance portion upstream of the inlet of the introduction pipe in the water pipe.

  According to the present invention, the negative pressure generated in the water flow of the water pipe is caused to act on the oxygen-enriched membrane from the introduction pipe, so that the high-concentration oxygen-enriched air generated in the oxygen-enriched film is passed from the introduction pipe to the water pipe. Since the vacuum pump is not necessary, the cost is reduced. In addition, since a large installation space such as a vacuum pump is not required and the space for disposing the vacuum pump can be omitted, the entire apparatus can be designed to be compact, and therefore can be installed in a small space. Furthermore, since there is no failure like a vacuum pump, durability is improved.

  According to the second aspect, if a water pump is connected to the water pipe, a high-pressure water flow can flow through the water pipe. Alternatively, if a water pipe is connected to the water pipe, a high-pressure water stream can flow through the water pipe.

  According to the third aspect, since the vacuum pressure is generated on the suction side of the water pump, the negative pressure is lowered, so that the oxygen concentration of the oxygen-enriched air can be increased.

  According to the fourth aspect, since the negative pressure on the downstream side of the water flow resistance portion is reduced, the oxygen concentration of the oxygen-enriched air can be increased.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a fine bubble generating bathtub 1, and a discharge (fine bubble generating) nozzle 2 and a suction port 3 are provided on the side wall of the bathtub 1, and the discharge nozzle 2 and the suction port 3 are provided for circulation. They are connected by a water pipe 4.

  The water pipe 4 is provided with a circulation pump (water pump) 5. By driving the circulation pump 5, the hot water in the bathtub 1 is sucked from the suction port 3 and discharged through the water pipe 4. It discharges in the bathtub 1 from.

  The oxygen-enriched air introduction device 11 receives oxygen-enriched film 12, a ventilation fan 13 that ventilates the surface air of the oxygen-enriched film 12, and high-concentration oxygen-enriched air generated by the oxygen-enriched film 12. The introduction pipe 14 is introduced into the water pipe 4 from the introduction port 14 a, and the introduction port 14 a of the introduction pipe 14 is set on the upstream side (suction side) of the circulation pump 5.

  A dissolution tank 15 is provided in the water flow pipe 4 on the downstream side (discharge side) of the circulation pump 5.

  Then, when the circulating pump 5 is driven, the hot water in the bathtub 1 is sucked from the suction port 3 and discharged from the discharge nozzle 2 into the bathtub 1 through the water conduit 4 and is generated in the oxygen-enriched air introducing device 11. The oxygen-enriched air having a high concentration is introduced into the water pipe 4 from the inlet 14a of the inlet pipe 14, and the introduced oxygen-enriched air is dissolved in the bath water by mixing and stirring in the dissolution tank 15, When discharging from the discharge nozzle 2 into the bathtub 1, re-vaporization causes fine bubbles to be generated. These fine bubbles usually contain oxygen having an oxygen concentration of about 30% when the oxygen concentration is about 21%.

  Next, an apparatus for introducing the high-concentration oxygen-enriched air generated in the oxygen-enriched air introduction device 11 from the introduction port 14a of the introduction pipe 14 into the water conduit 4 will be described.

  By applying a negative pressure to the oxygen-enriched film 12, high-concentration oxygen-enriched air is generated. That is, as shown in FIG. 6, the oxygen-enriched film 12 has a characteristic that the oxygen concentration and the flow rate increase as the acting negative pressure decreases.

  Therefore, conventionally, a vacuum pressure is applied to the oxygen-enriched membrane 12 by a vacuum pump. However, in the oxygen-enriched air introducing device 11 of the present embodiment, a circulation water pipe is used instead of the vacuum pump. 4, negative pressure generated in the water flow of the water pipe 4 when the circulation pump 5 is driven is applied to the oxygen-enriched membrane 12 from the introduction pipe 14 by using the existing circulation pump (water pump) 5 interposed By doing so, high-concentration oxygen-enriched air produced in the oxygen-enriched membrane 12 is introduced from the introduction pipe 14 into the water pipe 4.

  According to the oxygen-enriched air introduction device 11 of the present embodiment, the oxygen-enriched air 12 is caused to act on the oxygen-enriched membrane 12 from the introduction pipe 14 by applying a negative pressure generated in the water flow of the water pipe 4 accompanying the driving of the circulation pump 5. Since the high-concentration oxygen-enriched air produced by the chemical membrane is introduced from the introduction pipe 14 to the water pipe 4, a vacuum pump is not necessary and the cost is reduced. In addition, since a large installation space such as a vacuum pump is not required and the space for disposing the vacuum pump can be omitted, the entire apparatus can be designed to be compact, and therefore can be installed in a small space. Furthermore, since there is no failure like a vacuum pump, durability is improved.

  Further, a high-pressure water flow can be caused to flow through the water conduit 4 by the driving force of the circulation pump 5. Furthermore, as shown in detail in FIG. 2 (a), the introduction port 14a of the introduction pipe 14 of the water flow pipe 4 is provided on the suction side of the circulation pump 5, so that the circulation pump 5 is provided as shown in FIG. 2 (b). Since a vacuum pressure is generated on the suction side, the negative pressure is lowered, so that the oxygen concentration of the oxygen-enriched air can be increased. As shown in FIG. 3, the introduction port 14 a of the introduction pipe 14 of the water pipe 4 can be provided on the discharge side of the circulation pump 5.

  4 (a) and 4 (b) show a shower device 20, (a) is a water pipe connection type, and (b) is a pressurization pump (water pump) connection type.

  In FIG. 4A, the shower head 21 is connected to the other end 4b of the water pipe 4 in which one end 4a is connected to the water pipe 23.

  The oxygen-enriched air introduction device 11 includes an oxygen-enriched film 12, a ventilation fan 13 that ventilates the surface air of the oxygen-enriched film 12, and a high-concentration oxygen-enriched product generated by the oxygen-enriched film 12. The inlet pipe 14 introduces air into the water pipe 4 from the inlet 14a.

  In the process of flowing tap water from the water pipe 23 to the water pipe 4, high-concentration oxygen-enriched air generated in the oxygen-enriched air introduction device 11 is introduced into the water pipe 4 from the introduction port 14 a of the introduction pipe 14. As a result, the oxygen-enriched air-mixed water is partly dissolved in the tap water by the pressure in the water pipe 4 and discharged from the shower head 21 as supersaturated dissolved oxygen water.

  In the shower device 20 of FIG. 4A, the negative pressure generated in the water flow of the water pipe 4 that is directly connected to the water pipe is caused to act on the oxygen-enriched film 12 from the introduction pipe 14 to be generated in the oxygen-enriched film 12. The high-concentration oxygen-enriched air is introduced into the water pipe 4 from the introduction pipe 14.

  As described above, if the water pipe 23 is connected to the water pipe 4, a high-pressure water flow can be caused to flow through the water pipe 4 by the tap water.

  As shown in FIG. 4B, a pressure pump (water feed pump) 22 is interposed in the water pipe 4, and the introduction port 14a of the introduction pipe 14 is set on the upstream side (suction side) of the pressure pump 22. You can also.

  Thus, if the pressurization pump 22 is provided in the water flow pipe 4, a high-pressure water flow can be caused to flow through the water flow pipe 4 by the driving force of the pressure pump 22.

  In each of the above embodiments, as shown in FIGS. 5 (a) and 5 (b), a water flow resistance portion (orifice, ejector, mesh, bent pipe, etc.) is provided upstream of the introduction port 14a of the introduction pipe 14 of the water flow pipe 4. ) 24 can be provided.

  When such a water flow resistance portion 24 is provided, the negative pressure P2 on the downstream side becomes higher than the negative pressure P1 on the upstream side of the water flow resistance portion 24 (P1 <P2), so oxygen in the oxygen-enriched air The concentration can be increased.
