Description

Detailed Description of the Invention "Object of the Invention" Industrial Application Field The present invention relates to an improvement in an ozonated water supply device that generates and supplies ozonated water used for washing vegetables and fish from well water and tap water. It is something.

Conventional technology Ozonated water has traditionally been used as washing water for vegetables and fish, but ozonated water generated by conventional ozonated water generation and supply equipment has an inconsistent ozone concentration, making it difficult to wash vegetables and fish. When used as ozone water, the ozone concentration was measured each time, and if the concentration was low, the ozone water was increased, or if it was high, the ozone water was diluted, so that the ozone water had a constant concentration.

Therefore, a considerable amount of time was required to wash vegetables and fish, resulting in poor work efficiency.

In addition, conventional ozonated water generation and supply devices generate ozonated water containing harmful substances such as nitrogen oxides, and therefore cannot be used as ozonated water for cleaning in some cases.

Further, with conventional ozonated water generation and supply devices, it was not possible to continuously generate and supply ozonated water, and it was also not possible to simultaneously generate and supply ozonized air and ozonated water using the same device.
