PROBLEM TO BE SOLVED: To provide an ozone generating apparatus with which a time period required for reaching an appropriate ozone concentration in accordance with a room to be used is shortened.SOLUTION: The ozone generating apparatus includes a calculation part not shown in the figure. The calculation part calculates: a final ozone generation amount for finally keeping ozone concentration of a room at predetermined ozone concentration A1 based on the volume of the room to be used an initial ozone generation amount set to be three times as large as the final ozone generation amount, and an initial time period T1 required for room ozone concentration to reach the predetermined ozone concentration A1 based on the initial ozone generation, referring to a graph of a solid line in Fig.(1). The ozone generating apparatus first generates ozone of the initial ozone generation amount during the initial time period T1, and as a result, the ozone concentration in the room to be used becomes the predetermined ozone concentration A1. At the moment, the ozone generating apparatus switches the ozone generation amount from the initial ozone generation amount to the final ozone generation amount, and as a result, the time period required for reaching the predetermined ozone concentration A1 is more shortened compared with a case in which the ozone concentration changes according to a graph of a two-dot chain line indicating continued ozone generation with the final ozone generation amount from the beginning.COPYRIGHT: (C)2013,JPO&INPIT【課題】 使用する部屋に応じて適切なオゾン濃度に到達するまでの時間を短縮することのできるオゾン発生装置を提供する。【解決手段】 (1)の実線のグラフを参照して、オゾン発生装置は、図示しない演算部によって、使用すべき部屋の容積に基づいて、部屋のオゾン濃度が最終的に所定のオゾン濃度A1に維持される最終オゾン発生量と、最終オゾン発生量の3倍に設定された初期オゾン発生量と、初期オゾン発生量に基づいて部屋のオゾン濃度が所定のオゾン濃度A1に達するまでに要する初期時間T1とが演算される。そして、まず初期オゾン発生量を初期時間T1発生させる。すると、使用する部屋が所定のオゾン濃度A1となる。この時点で初期オゾン発生量を最終オゾン発生量に切り替えて発生する。すると、最終オゾン発生量で最初から継続する二点鎖線によるオゾン濃度の変化に比べて、所定のオゾン濃度A1に達するまでの時間が短縮される。【選択図】 図7
