となると言う問題点があった。In the conventional water curtain generator as described above, the speed and flow rate of water exiting from the injection port 4 are uniform in the circumferential direction. For this reason, in general, the shape of the conventional water curtain 5 is a fan shape having a width of 3 to 4 times the length of the height.
Generally, when a water curtain is formed indoors, the width of the water curtain 5 is often limited. When the water curtain generator is used indoors, the height of the water curtain 5 is limited due to the limitation of the width of the water curtain 5. There was a problem that it had to be reduced, and it lacked the power of a water curtain.
