Abstract

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.

Claims

1. A humidifier, comprising:

a base housing, comprising first and second spaced electrical terminals, first and second recesses, said first recess including a pin projecting therefrom and an aperture, and a vibrator spray section for the emission of moisture and connected to said first recess through said aperture; and

a water tank adapted to be mounted onto said base housing and comprising a porous divider dividing said water tank into two equal sections each including first and second valve members respectively engageable with said first and second recesses with said water tank mounted onto said base housing, first and second cavities in the bottom of said tank having electrodes mounted thereon for accommodating said first and second electrical terminals, each of said valve members including a springbiased valve member closing an aperture in said tank, said first valve member engaging said pin to open said first valve member and said second valve member being received in said second recess whereby said second valve member is closed with said water tank mounted onto said base member.

2. A humidifier as claimed in claim 1 wherein said water tank includes a transparent top with a recessed handle therein.

3. A humidifier as claimed in claim 1 wherein said water tank is symmetrical such that it can be mounted onto said base housing with said first and second valve members rotated by one hundred eighty degrees.
