<p>A humidifier for sterilizing bacilli by alteration of the alkalinity of water in a water tank to sterilize it and automatically remove scale on the internal walls of the water tank. The humidifier includes a base housing with spaced first and second electrical terminals, first and second recesses with a pin projecting therefrom and an aperture. A vibrator spray section emits moisture and is connected to the first recess through the aperture. The water tank is removably mounted onto the base housing and includes a porous divider for dividing the tank into substantially equal sections each including first and second valve members respectively engageable with the first and second recesses. Cavities in the bottom of the tank have electrodes mounted thereon for accommodating the first and second electrical terminals. Each of the valve members includes a spring-biased valve closing an aperture in the tank with the first valve member engaging the pin to open the first valve and the second valve being received in the second recess whereby the second valve is closed with the water tank mounted on the base housing.</p> |
