Abstract
A decontamination device capable of confirming accurate operations of a mist circulation dispersion means before and after or during a decontamination operation and guaranteeing the overall operation as a decontamination device.The device includes a mist supply means, a mist circulation dispersion means, and an ultrasonic detection means. The mist supply means converts a chemical for decontamination of the inside of a working chamber of the device into a mist for decontamination and supplies such mist to the inside of the working chamber. The mist circulation dispersion means subjects a vibrating board (which includes a plurality of ultrasonic transmitters) to ultrasonic vibration to generate sound flows with ultrasound from board surfaces in the vertical direction and presses the mist with acoustic radiation pressure of the sound flows in order to circulate and disperse the mist for decontamination in the working chamber. The ultrasonic detection means includes an ultrasonic receiver configured to detect the operation of the plurality of ultrasonic transmitters included in the vibrating board in as a whole and/or the operation of each of the constituent ultrasonic transmitters.
