Abstract
A method an apparatus for disposing of urine is described comprising a funnel-like basin connected to a pump housing. The housing contains a fluid pump connected to the drain of the basin and activated by a fluid pressure sensor when the fluid pressure in the basin exceeds a predetermined value. The housing also contains means for connecting an external fresh water supply to the basin when the fluid pressure in the basin drops below a predetermined value.
Claims3
A urine disposal device comprising:
- a funnel-like basin adapted to hold a fluid reservoir, said basin having an upper and a lower section, said lower section having a diameter that is smaller than a diameter of said upper section, said upper section having an opening;
- a drain extending from said lower section;
- a pump housing connected to said drain;
- an electro-mechanical fluid pump located within said housing;
- an inlet valve connected to said basin at the opening and adapted for connection to a fresh water supply;
- first and second sensors located within said housing, said first sensor operationally controlling said pump and said second sensor operationally controlling said inlet valve.

A urine disposal device comprising:
- a funnel-like basin adapted to contain a fluid reservoir, said basin having an upper section with a first diameter, a lower section connected to said upper section, said lower section having a second diameter less than said first diameter of said upper section, said upper section having an opening;
- an inlet valve having an open and a closed position, said valve being connected to the basin at the opening in said basin and being adapted for connection to an external water supply;
- a pump housing connected to said basin;
- a drain extending downwardly from said lower section of said basin into said pump housing;
- an electro-mechanical fluid pump located within said housing;
- a discharge valve connected to said pump and adapted to connect to an external waste area;
- and
- first and second fluid pressure sensors, said first fluid pressure sensor initiating the operation of said pump when said first fluid pressure sensor detects a fluid level within said housing that exceeds a first predetermined level, and said second fluid pressure sensor opening said inlet valve when said second fluid pressure sensor detects a fluid level within said housing below a predetermined level.
