Combined toilet & urinal

Abstract

A combined toilet and urinal has a flush tank and a toilet having a toilet bowl mounted to the flush tank and having a water input from the flush tank and a siphon outlet. The waterless urinal has a urinal bowl having a drain therein. The toilet bowl and urinal bowl are formed in one dual bowl toilet body. A drain tube connects the urinal drain to the toilet siphon outlet of the toilet bowl for draining urine from the waterless urinal and a floatable drain cover is positioned in the waterless urinal bowl to cover the drain opening in the absence of liquid in the bowl and uncovers the urinal drain opening when liquid in the urinal bowl floats the drain cover. The drain cover can be a floatable ball, such as a hollow plastic sphere, while the urinal ball is shaped to direct the free-floating bowl over the drain whenever there is no liquid in the urinal bowl. The urinal bowl has a bottom portion shaped to guide the floatable drain cover over the drain opening.
