Abstract

A toilet includes a dehumidifier operable to draw water vapor from the air and discharge water. A tank is configured to store the water discharged from the dehumidifier. A drain valve is movable from a closed position to an open position whereby the toilet is flushed solely with the water discharged from the dehumidifier and stored in the tank.

Claims (39)

1. A toilet comprising:

a dehumidifier operable to draw water vapor from the air and discharge water;

a tank divided into a first chamber and a separate second chamber, wherein the second chamber includes an inlet for connection with a standard building water supply, and the first chamber has no inlet for connection with a standard building water supply, the first chamber being configured to receive and store only water discharged from the dehumidifier;

a bowl coupled to the tank to receive water from the tank;

a first drain valve positioned in the first chamber and movable from a closed position to an open position whereby the toilet bowl is flushed solely with the water discharged from the dehumidifier and stored in the first chamber of the tank;

a second drain valve positioned in the second chamber and movable from a closed position to an open position whereby the toiled bowl is flushed with water from the second chamber;

a humidity control input that controls the running of the dehumidifier to maintain a desired humidity level in the surrounding air; and

a float switch positioned inside the first chamber of the tank and operable to prevent the running of the dehumidifier when the amount of water accumulated in the first chamber of the tank reaches a predetermined flush volume,

wherein the dehumidifier is positioned on top of the tank to provide a cover for the tank.

2. The toilet of claim 1 , further comprising a first flush handle coupled to the first drain valve and a second flush handle coupled to the second drain valve.

3. The toilet of claim 1 , further comprising a visual indicator responsive to the amount of water discharged from the dehumidifier to provide a visual indication when the amount of water accumulated from the dehumidifier reaches a predetermined flush volume of water in the first chamber of the tank.

4. The toilet of claim 3 , wherein the visual indicator is a light configured to be illuminated in response to a float switch inside the first chamber of the tank.

5. The toilet of claim 1 , wherein the dehumidifier includes a housing having a perimeter shape substantially identical to a perimeter shape of the tank.

6. A toilet comprising:

a dehumidifier operable to draw water vapor from the air and discharge water;

a tank having a first chamber configured to receive and store the water discharged from the dehumidifier and having no inlet for connection to a standard building water supply, and a second chamber, separate from the first chamber, configured to receive and store water, the second chamber having an inlet for connection with a standard building water supply;

a bowl coupled to the tank to receive water from the tank;

a flushing mechanism operable to enable selective flushing of the toilet bowl with only water from the first chamber;

a humidity control input that controls the running of the dehumidifier to maintain a desired humidity level in the surrounding air; and

a float switch positioned inside the first chamber and operable to prevent the running of the dehumidifier when the amount of water accumulated in the first chamber reaches a predetermined flush volume,

wherein the dehumidifier is positioned on top of the tank to provide a cover for the tank.

7. The toilet of claim 6 , wherein the flushing mechanism includes two independent drain valves operable by two independent flush handles, wherein a first one of the flush handles is operable to open a first one of the drain valves, which is positioned in the first chamber, to enable flushing of the toilet bowl solely with water from the dehumidifier that is stored in the first chamber.

8. The toilet of claim 6 , further comprising a visual indicator responsive to the water level in the first chamber to provide a visual indication when the amount of water in the first chamber reaches a predetermined flush volume.

9. The toilet of claim 8 , wherein the visual indicator is a light configured to be illuminated in response to a float switch inside the first chamber.

10. The toilet of claim 6 , wherein the dehumidifier includes a housing having a perimeter shape substantially identical to a perimeter shape of the tank.

11. A toilet comprising:

a dehumidifier operable to draw water vapor from the air and discharge water;

a tank having a first chamber configured to receive and store the water discharged from the dehumidifier and a second chamber, separate from the first chamber, configured to receive and store water from a standard building water supply, the first chamber having no inlet for connection to a standard building water supply;

a bowl coupled to the tank to receive water from the tank;

a first flush handle operable to actuate a first drain valve for flushing the toilet bowl solely with water from the first chamber that has been discharged from the dehumidifier;

a second flush handle operable to actuate a second drain valve for flushing the toilet bowl with water from the second chamber that has been supplied by the standard building water supply;

a float switch positioned in the first chamber and operable to disable the operation of the dehumidifier when the water level in the first chamber meets a predetermined level; and

an indicator light operable to illuminate in response to the water level in the first chamber reaching the predetermined level,

wherein the dehumidifier is positioned on top of the tank to provide a cover for the tank.

12. The toilet of claim 11 , wherein the dehumidifier includes a housing having a perimeter shape substantially identical to a perimeter shape of the tank.

13. The toilet of claim 11 , wherein the first tank and the second tank are of substantially equal volume.

14. The toilet of claim 1 , wherein only the first chamber is configured to receive water discharged from the dehumidifier.

15. The toilet of claim 6 , wherein only the first chamber is configured to receive water discharged from the dehumidifier.

16. The toilet of claim 11 , wherein only the first chamber is configured to receive water discharged from the dehumidifier.
