Is shown. Conventional aerial discharges are greatly affected by ambient temperature fluctuations. When the ambient temperature is low, the amount of ozone generation increases. Conversely, when the ambient temperature increases, the amount of ozone generation decreases. On the other hand, since the underwater discharge of the present invention generates ozone gas by liberation from ozone water, the influence of ambient temperature fluctuation is smaller than that of air, and the fluctuation range of ozone generation amount due to ambient temperature fluctuation is also small. Therefore, the embodiment of the present invention that generates ozone gas from ozone water can generate ozone gas more stably.

  As described above, in the present embodiment, the water storage tank 210 that stores water, the liquid supply means 310 that supplies water from the water storage tank 210 to the outside of the water storage tank 210 using the capillary action, and the liquid supply means 310 Ozone water obtained by decomposing dissolved oxygen in the water in the liquid feeding means 310, having the ozone generating section 320 disposed, and the air blowing means 330 for giving forced convection in the vicinity of the downstream end 313b of the liquid feeding means 310 In the present embodiment, the amount of ozone gas generated by normal air discharge is greatly affected by ambient temperature fluctuations and is difficult to generate stably. Since the influence of ambient temperature fluctuation is smaller than that of air, the influence on the amount of generated ozone gas is reduced, and a safe low-concentration ozone gas can be stably supplied to the human body.

  As described above, the ozone water, ozone mist, and ozone gas generator according to the present invention stably generates low-concentration ozone water, low-concentration ozone mist, and low-concentration ozone gas, and performs high-performance deodorization and removal. Since bacteria and harmful substances can be removed, the present invention can be applied to household refrigerators, commercial refrigerators, food cleaners, dishwashers, medical instrument cleaners, and the like.
