The air inlet p for inflowing air into the mixed flow nozzle body 1 and the mixed flow jetting part t are connected to the mixed flow nozzle body 1.
Since the structure is such that the direction is changed in one piece, when the direction is changed, the outflow pipe f
Before reaching the driven flow nozzle part n, the hot water ejected from the hot water collides with the wall surface of the introduction part U and is decelerated, resulting in a reduction in the amount of air sucked in compared to a state where the direction is not changed. Furthermore, in the conventional mechanism, the driving flow nozzle part n is configured on the central axis of the mixing space 0, so that the ejected flow flows into the mixing space. It is difficult to get close to the inner wall of the pipe, and a sufficient air suction effect cannot be obtained.

構成としても良い。First, in the device of the present invention, an attachment opening 14 slightly larger than the outer diameter of the cylindrical portion 13 of the tightening cylindrical member 10 is formed in advance on the wall of the bathtub 12, and the outer cylindrical member 7 is inserted into the attachment opening from the outside of the bathtub 12. 14, the tubular portion 13 of the tightening tubular member 10 is inserted into the attachment port 14 from the inside of the bathtub 12, and is screwed onto the outer tubular member 7 and tightened. Installation is in good condition. Then, an outgoing pipe 4 connected to the hot water supply device 3 is connected to the upstream side of the driven flow nozzle section 2 to put it into use. Further, a return pipe 16 to the hot water supply device 3 is connected to the bathtub 12 via a suitable hot water outlet member 15. In addition, the short pipe 17 forming a part of the outgoing pipe 4 is fixed in advance to a predetermined position of the inner cylinder member 1 by brazing or the like, and the short pipe 17 is
The configuration may be such that the outgoing pipe 4 connected to the water heater 3 is connected, or alternatively, an outgoing pipe connecting member may be provided in advance at a predetermined position of the inner cylinder member 1, and the outgoing pipe 4 may be connected by this connecting member. good.

。Therefore, the water supply pump 18 of the water heater 3 causes the outgoing pipe 4 to
The hot water that has flowed into one side of the inner cylinder member 1 through the driven flow nozzle part 2 is ejected into the mixing space 19 on the downstream side near the driven flow nozzle part 2.
At this time, air in the air chamber 6 is sucked in through the suction port 9. In this way, the driving flow of hot water and the secondary flow of air gradually mix and flow toward the other side of the inner cylinder member 1, and after being sufficiently mixed, are ejected from the mixed flow nozzle portion 5 into the bathtub 12. The hot water in the bathtub 12 returns from the hot water outlet member 15 to the suction side of the hot water pump 18 of the hot water supply device 3 via the return pipe 16 and is circulated. The hot water whose pressure has been increased by the hot water pump 18 is appropriately heated by the heat exchanger 20, and flows into the bathtub 12 via the outgoing pipe 4 again as described above. At this time, outside air flows into the air chamber 6 through the air pipe 8 and is used for the mixing. If the air pipe 8 is provided with an on-off valve 21 and closed as necessary,
Only hot water can be circulated without mixing air.

に、空気を十分に混合した湯を噴出することができる。In the above operation, by changing the direction of the mixed flow nozzle section 5 as shown by the imaginary line in FIG. 2, the ejection direction of the mixed flow of hot water and air can be adjusted as appropriate. Even if the direction of the mixed flow nozzle part 5 is changed in this way, the direction of the inner cylinder member 1 itself does not change, and the relative relationship between the inner cylinder member 1 and the outgoing pipe 4 does not change, so the driving flow nozzle part 2
The hot water gushing from the tank is not slowed down, and the amount of air sucked in remains unchanged. Therefore, hot water sufficiently mixed with air can be spouted without being affected by the direction of the mixed flow nozzle section 5.
また、駆動流ノズル部２は前記混合空間９に対して偏心

なる気泡発生を行えるという効果がある。(Effects of the Invention) As described above, the present invention provides a driving flow nozzle section on one side of the inner cylinder member, sucks air from the surrounding air chamber and mixes it, and connects the mixed flow nozzle section to the inner cylinder member. By supporting the other side of the member so that the direction can be changed, the mixed flow of hot water and air can be adjusted and ejected into the bathtub in an appropriate direction. Unlike the conventional structure in which the pipe is constructed as one piece and the direction is changed in one piece, there is no decrease in the amount of air sucked in due to the deceleration of the hot water spouted from the outgoing pipe when the direction is changed, that is,
Even if the direction of the mixed flow nozzle section is changed, the direction of the inner cylindrical member itself does not change, and the relative relationship between the inner cylindrical member and the outgoing pipe does not change, so the ejection speed from the driving flow nozzle section does not change. ,
Therefore, there is an effect that hot water sufficiently mixed with air can be spouted without being influenced by the direction of the mixed flow nozzle section. Further, in the present invention, the driving flow nozzle section is configured to be eccentric with respect to the mixing space on the downstream side thereof, so that the ejected flow of hot water comes into contact with the inner wall of the mixing space on the eccentric side, and is then sufficiently Since it spreads, a sufficient air suction effect can be obtained and sufficient bubble generation can be achieved.
