噴出する気泡水流発生装置に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bubble water flow generation device that blows a bubble water flow into a bathtub by forcibly supplying air immediately after a water flow discharge nozzle communicating with a pump.

号公報）。2. Description of the Related Art A conventional bubble water flow generator of this type has a configuration as shown in FIG. As shown in the figure, hot water in a bathtub 8 is sucked by a circulation pump 6 through a pipe 7, a mixing chamber 4 is provided downstream of the circulation pump 6, and the tip of the mixing chamber 4 is opened into the bathtub 8. . The mixing chamber 4 includes a water jet nozzle 1 having a horizontal axis and an air-water mixing nozzle 2,
And the mixed-air suction section 3 whose axis is orthogonal to the two nozzle axes (for example, see Japanese Utility Model Application Laid-Open No. 63-188027).

微細化には限界があった。Problems to be Solved by the Invention In such a conventional configuration, the intake air is sucked from around the jet water by the jet action of the water flow, so that only a relatively large bubble size is generated. This is because the air mass contacts the water flow in the laminar diffusion layer around the jet water, and the air mass is reduced by the laminar shear force. However, since the flow velocity of water in the laminar diffusion layer is slow and the contact area between water and air is small, large energy is not transferred from the water flow to the air mass, so there is a limit to the miniaturization of bubbles. .
つぎに空気塊は層流境界層から乱流領域に移送され、

の微細化には限界があった。Next, the air mass is transferred from the laminar boundary layer to the turbulent region,
Here, it is micronized by turbulent shearing force due to momentum exchange with water particles, but it requires very large energy to break the air mass once formed. There was a limit.

By doing so, the air delivered from the tip of the small-diameter micro air supply pipe immediately
It is blown off by the dynamic pressure energy of the water flow and becomes fine bubbles, which are mixed with the water flow to become a fine bubble water flow,
It is sent downstream and eventually squirts into the bath as a fine bubbled water stream.

In addition, a fine bubble water flow can be realized with much less energy than a conventional bubble water flow generator.

された小口径の空気供給管３より構成されている。As shown in FIGS. 1 to 3, the mixing chamber 4 is disposed immediately downstream of the water jet nozzle 1, the air / water mixing nozzle 2, and the water jet nozzle 1, which are installed to face each other at a predetermined distance. The air supply pipe 3 has a small diameter.

The hot water sucked from the bathtub 8 through the pipe 7 is turned into a high-speed water flow by the water flow jet nozzle 1 having a reduced area, and is jetted into the mixing chamber 4. At the same time, the air pump 5 is operated to supply the air in the bathroom through the air supply pipe 3 immediately after the water jet nozzle 1 in the mixing chamber 4. The air mass delivered from the tip of the small-diameter air supply pipe is blown off by the water flow pressure energy to form a fine air mass, which mixes with the water flow to form a fine bubble water flow and is sent into the bathtub.

可能となるものである。In this case, the energy required to create fine bubbles is the sum of the kinetic energy for blowing off the air mass from the air supply tube and the energy that overcomes the frictional force acting between the air mass and the air supply tube. It is possible to realize a fine bubble water flow with much less energy than conventionally.

By disposing, it is possible to create microbubbles with a large amount of air and to make the mixing of the water flow and the bubbles more uniform.
