The principal part expanded sectional view which shows an Example, FIG. 4: is a principal part expanded sectional view which shows 3rd Example of the gas mixing water production | generation apparatus by this invention. In FIG. 1, reference numeral 1 denotes a humidifying device, in which a gas-mixed water generating device 5 and an atomizing device 30 are arranged in a water tank 2.

The gas-mixed water generating device 5 is configured as shown in FIGS. That is, the water flow passage 7 is formed in the casing 6. The flow passage 7 has an inflow portion 8, a throttle portion 9, a conical portion 10, and a guide portion 11 that are connected in series and coaxially from the lower portion to the upper portion in the axial center portion of the casing 6. Four outflow passages 14 are formed radially on the peripheral wall of the outer peripheral wall, and the upper portion of the guide portion 11 is opened into the water tank 2 through the outflow passage 14.

The upper part of the inflow part 8 is reduced in a tapered shape so as to communicate with the throttle part 9, a pipe joint 15 is screwed into the lower part of the inflow part 8, and the discharge pipe 17 of the pump 16 is connected via the pipe joint 15. Connecting. The pump 16 is installed outside the water tank 2, the suction port of the suction pipe 18 is arranged at the bottom of the water tank 2, and the water in the water tank 2 is supplied to the inflow part 8 at a pressure of 0.1 Mpa or more. It has become.

The conical part 10 expands in a tapered shape upward from the upper part of the throttle part 9, and its upper end communicates with the straight guide part 11. The upper end of the guiding portion 11 is blocked by a collision wall 12 that extends in the radial direction, and a large number of uneven portions 13 are formed on the entire collision surface (inner surface) of the collision wall 12. The collision surface of the collision wall 12 may be flat as shown in FIG. 1, and a large number of uneven portions 13 may be formed on the flat collision surface. As shown in FIG. 3, the collision surface is a concave surface 12a. In addition, a large number of small concave portions (dimples) 13a may be formed on the concave surface 12a.

A gas supply pipe joint 22 is screwed into the gas inflow passage 21, and a supply pipe 26 of an ozone generator 25 installed outside the water tank 2 is connected to the pipe joint 22. Reference numeral 27 denotes a control valve that adjusts the supply amount of ozone.

The above-described atomizing device 30 is a conventionally known ultrasonic type, and the ultrasonic vibrator 31 is slightly vibrated to atomize the water in the water tank. The atomized water is externally introduced by the induction case 32. To guide. The atomizing device 30 is operated after a certain period of time has elapsed since the pump 16 and the ozone generating device 25, that is, the gas-mixed water generating device 5 are operated. Note that a fan may be attached in the guide case 32 so that water atomized by the fan is forcibly ejected to the outside.

According to the embodiment, when the pump 16 is started in a state where the ozone generator 25 is operated, the water in the water tank 2 is pressurized and supplied to the inflow portion 8 through the suction pipe 18 and the discharge pipe 17. The water supplied to the inflow portion 8 flows from the throttle portion 9 toward the conical portion 10 and the guiding portion 11 at a high speed. At this time, a negative pressure is generated in the negative pressure chamber 20 formed in the communication portion between the throttle portion 9 and the conical portion 10, and ozone is sucked into the portion from the gas inflow path 21.
