Abstract

The toilet bowl separately collects urine and feces for analysis or use in a composting device, waste digester, or to reclaim water. The toilet bowl includes a toilet bowl wall. Urine flows down the toilet bowl wall into a channel for collection. The channel surrounds an aperture into which feces may be deposited. Consequently, urine and feces are kept separate during collection. Both the channel and the aperture may be connected to conduits which may transmit material into analytical devices. The conduits may transmit material into digesters in appropriate amounts including controlling the amount of liquid added to solid material. Collected urine may be stored for water reclamation. Sensors may confirm the absence of fecal matter in collected urine or detect contamination. After separate analysis, feces and urine may be combined through connecting conduits then disposed of in the sewer system or sent to a composting device or waste digester.

First claim

We claim:

1. A toilet bowl for separately collecting urine and feces comprising:
a. a bowl, the bowl comprising:
i. a toilet bowl wall;
ii. a channel, the channel comprising an inner and an outer channel wall, wherein toilet bowl wall surrounds the channel; and
iii. an aperture, wherein the inner channel wall defines the aperture;

b. a fecal conduit, wherein the fecal conduit is in communication with the aperture;
c. a urine conduit, wherein the urine conduit is in fluid communication with the channel;
d. a urinalysis device, wherein the urinalysis device is in fluid communication with the urine conduit; and
e. a urine return conduit,
i. wherein the urinalysis device is disposed between the urine conduit and the urine return conduit;
ii. wherein the urine return conduit is in communication with the fecal conduit at a point where urine return conduit and the fecal conduit combine; and
iii. wherein the fecal conduit is in communication with a sewer, composting device, or waste digester at a point which is distal to the point where urine return conduit and the fecal conduit combine.

2. The toilet bowl of claim 1 , wherein a lower section of the toilet bowl wall defines the outer channel wall.

3. The toilet bowl of claim 1 , wherein the inner channel wall, the outer channel wall, or both the inner and outer channel walls comprise a rim.

4. The toilet bowl of claim 3 , further comprising at least one sensor, wherein the at least one sensor is disposed on the rim.

5. The toilet bowl of claim 4 , wherein at least one of the at least one sensors comprises a capacitive sensor.

6. The toilet bowl of claim 1 , wherein the inner channel wall, the outer channel wall, or both the inner and outer channel walls are inclined at a first angle.

7. The toilet bowl of claim 6 , wherein the first angle is directed away from the aperture.

8. The toilet bowl of claim 1 , wherein the toilet bowl wall is inclined at a second angle, and wherein the second angle is between about 40 degrees and about 70 degrees from a horizontal plane.

9. The toilet bowl of clam 1 , further comprising:
a. an optical sensor;
b. a spectrometer; and
c. a first and a second optical window, wherein the first optical window is disposed within the inner channel wall and the second optical window is disposed within the outer channel wall, and wherein the spectrometer measures a spectrum of light transmitted out of the channel through the second optical window.

10. The toilet bowl of claim 1 , wherein the fecal conduit is in communication with an analytical device capable of analyzing feces.

11. The toilet bowl of claim 1 , further comprising one or more flush water dispensers, wherein the one or more flush water dispensers dispense flush water onto the toilet bowl wall.

12. The toilet bowl of claim 1 , further comprising one or more cleansing agent dispensers, wherein the one or more cleansing agent dispensers dispense one or more cleansing agents onto the toilet bowl wall.

13. The toilet bowl of claim 1 , wherein the inner channel wall forms an inverted truncated cone.
