PROBLEM TO BE SOLVED: To provide a denture washing device by which a sufficient sterilization effect can be obtained by using hydrogen peroxide.SOLUTION: In the denture washing device (10), there are provided a washing tank (40) and a discharge generator (50). A denture (100) to be washed is accommodated in the washing tank (40), and immersed into washing water. A discharge unit (50a) of the discharge generator (50) is placed in the washing tank (40), and brought into a state of being immersed into the washing water. A DC power supply (65) is connected to a pair of electrodes (51, 52) of the discharge unit (50a). When the DC of supply (65) applies voltages to the pair of electrodes (51, 52), streamer discharge is performed between the pair of electrodes (51, 52), and the hydrogen peroxide is produced. In the washing tank (40), the denture (100) is sterilized by using the hydrogen peroxide generated by the streamer discharge.COPYRIGHT: (C)2012,JPO&INPIT【課題】過酸化水素を用いて十分な殺菌効果が得られる義歯洗浄装置を提供する。【解決手段】義歯洗浄装置(10)には、洗浄槽(40)と、放電発生機(50)が設けられる。洗浄対象の義歯(100)は、洗浄槽(40)内に収容されて洗浄水に浸漬される。放電発生機(50)の放電ユニット(50a)は、洗浄槽(40)内に設置され、洗浄水に浸った状態となる。放電ユニット(50a)の電極対(51,52)には、直流電源(65)が接続される。直流電源(65)が電極対(51,52)に電圧を印加すると、電極対(51,52)の間でストリーマ放電が行われ、過酸化水素が生成される。洗浄槽(40)内では、ストリーマ放電によって生成した過酸化水素を用いて義歯(100)の殺菌が行われる。【選択図】図2
