- the induction electrodes 3 and 4 are formed using the wiring layer of the printed circuit board 5, but each of the induction electrodes 3 and 4 may be formed of a metal plate. In addition, each of the induction electrodes 3 and 4 may not be annular.
- the ion delivery apparatus was shown as an electric equipment using the ion generator 43, an air conditioner, a dehumidifier, a humidifier, an air cleaner, a refrigerator, a gas fan heater, a petroleum fan heater
- the ion generator 43 may be mounted on an electric device such as an electric fan heater, a washer / dryer, a vacuum cleaner, a sterilizer, a microwave oven, and a copying machine.

Abstract
Description
好ましくは、イオン発生装置は、絶縁材料をさらに備えている。誘導電極は、絶縁材料により密閉されている。放電電極は、絶縁材料から突出している。好ましくは、導電体が接合部から突出する長さは、絶縁材料から突出している放電電極の長さの半分以下である。
図1は、本発明の実施の形態1におけるイオン発生装置を示す斜視図である。図2は、図1に示したイオン発生装置の平面図である。図3は、図1に示したイオン発生装置の断面図である。図4は、図1に示したイオン発生装置から蓋部材を外した状態を示す斜視図である。まず、図1~図4を参照して、実施の形態1のイオン発生装置の構造について詳細に説明する。
図9は、実施の形態2におけるイオン発生装置を示す断面図である。実施の形態1のイオン発生装置では、プリント基板6の下面まで絶縁材料19が充填されていた。これに対し、図9に示す実施の形態2のイオン発生装置では、プリント基板6の上面側にも絶縁材料19が充填されている。絶縁材料19は、蓋部材11の内面にまで充填されている。誘導電極3,4は、図9に示すように、絶縁材料19により密閉されている。放電電極1,2は、絶縁材料19から突出している。絶縁材料19は、放電電極1,2と誘導電極3,4とを電気的に絶縁している。
図10は、実施の形態3におけるイオン発生装置を示す斜視図である。実施の形態3のイオン発生装置は、実施の形態1で説明した蓋部材11に替えて、エポキシ樹脂、ウレタン樹脂などの絶縁材料19を備えている。誘導電極3,4は、絶縁材料19により密閉されている。放電電極1,2は、絶縁材料19から突出している。放電電極1の導電体7が接合部7aから突出する長さは、絶縁材料19から突出している放電電極1の長さの半分以下である。放電電極2の導電体8が接合部8aから突出する長さは、絶縁材料19から突出している放電電極2の長さの半分以下である。実施の形態1の蓋部材11の表面に相当する位置まで絶縁材料19を充填することにより、絶縁材料19は、放電電極1,2と誘導電極3,4との間の電気絶縁の機能を奏している。
