PROBLEM TO BE SOLVED: To provide a sterilization device capable of continuously using a tableware washing sponge or the like in a clean state.SOLUTION: A body container 1 is provided with a network base to be placed with a sponge or the like for tableware washing and a leg rubber for vibration suppression. A body container cover is, at the inside, provided with suction port for performing suction from the outside, an electrostatic atomization generator unit for generating electrification fine particle water by electrostatic atomization, a wind feed rotary fan for performing suction from the outside and feeding wind from an exhaust port for wind feed to the main container and a motor for driving the rotary fan for wind feed rotary fan, the electrification fine particle water generated in the electrostatic atomization generation unit is released from the exhaust port for wind feed to the inside of the body container and pass through the depth of the inside of the sponge or the like on the network base to be placed with a sponge or the like for tableware washing at the inside while being securely infiltrated to perform deodorization and sterilization, thus a sponge or the like for tableware washing can be always cleanly retained.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】食器洗いスポンジ等を清潔な状態で継続的に使用することができる除菌装置を提供すること。【解決手段】本体容器1は、内部に食器洗い用スポンジ等を置く網目状の土台と、振動抑制用脚ゴムが設けられていて、本体容器蓋は、内部に外部から吸気を行う吸気口と静電霧化により帯電微粒子水を発生させる静電霧化発生装置ユニットと外部から吸気を行い送風用排気口から本体容器に送風させるための送風回転ファンおよび送風回転ファンを駆動させるためのモータを設け、静電霧化発生ユニットで発生させた帯電微粒子水を送風用排気口から本体容器内部に放出し、本体内部の食器洗い用スポンジ等を置く網目状の土台の上にあるスポンジ等の内部の奥深くを確実に浸透させながら通り抜けることで、脱臭・除菌を行うことができるので、食器洗い用スポンジ等を常時清潔に保つことができる。【選択図】図1
