Abstract
Abstract An odor elimination system for a portable toilet. The toilet comprises a bowl member charged initially with water to a predetermined level and having liquid and solid wastes deposited therein. A pair of electrodes is immersed in the water between the top and bottom of the bowl. The lower electrode can be formed by coating a conductive layer on the bottom of the bowl. Switching means connects the positive terminal of a D.C. voltage source to the lower electrode and the negative terminal to the upper electrode whereby oxygen forms at the bottom electrode and rises to the top of the water, oxidizing odors, bacteria and algae formed in the water.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
103 words
An odor elimination system for a portable toilet comprising: a bowl member for containing liquid and solid excreta and a reservoir of water; a first electrode floating adjacent the top level of said water; a second electrode immersed in said water adjacent the bottom level of said water and spaced from said first electrode; a source of D.C. voltage having a negative terminal and a positive terminal; and means for connecting said D.C. voltage source negative terminal to said first electrode and said positive terminal to said second electrode for generation of oxygen by electrolysis of said reservoir water at said second electrode.
Claim 2
Dependent Claim
