Abstract

Disclosed are devices, methods, and systems for generating and applying a magnetic field in a toilet. A toilet including a bowl having a discharge outlet, a trapway in fluid communication with the discharge outlet, and at least one magnet configured to generate a magnetic field to alter a flow of liquid through the trapway is described.

Claims (40)

1. A toilet comprising:

a bowl having a discharge outlet;

a trapway in fluid communication with the discharge outlet; and

at least one magnet configured to generate a magnetic field to directly alter a flow of water through the trapway.

2. The toilet of claim 1 , wherein the magnetic field is configured to assist a flow of water through the trapway during a flush cycle.

3. The toilet of claim 1 , wherein the at least one magnet is fixed to a pedestal of the toilet proximate to the trapway.

4. The toilet of claim 1 , wherein the at least one magnet includes a plurality of permanent magnets, the plurality of permanent magnets being arranged radially around the trapway or along the trapway.

5. The toilet of claim 1 , further comprising:

a power source,

wherein the at least one magnet comprises an electromagnet powered by the power source.

6. The toilet of claim 5 , further comprising:

a switch for activating or deactivating the at least one magnet.

7. The toilet of claim 5 , further comprising:

a sensor configured to collect sensor data; and

a controller configured to activate or deactivate the electromagnet in response to the sensor data.

8. The toilet of claim 7 , wherein the sensor data describes a presence of a user, a water level in the bowl, or a blockage in the trapway.

9. The toilet of claim 7 , wherein the controller is configured to activate and deactivate the electromagnet causing the electromagnet to generate a magnetic field in a series of pulses.

10. The toilet of claim 7 , wherein the controller is configured to increase a strength of the magnetic field over a period of time.

11. A toilet comprising:

a bowl having a discharge outlet;

a trapway in fluid communication with the discharge outlet;

at least one magnet configured to generate a magnetic field to alter a flow of water through the trapway;

a flexible membrane disposed within the trapway, the flexible membrane forming a portion of an interior surface of the trapway,

wherein the at least one magnet includes a driving magnet and a driven magnet, the driven magnet being coupled to the flexible membrane, and

wherein the driving magnet is configured to selectively generate a magnetic field repelling the driven magnet and causing the flexible membrane to elastically deform and extend into the trapway, altering the flow of water through the trapway.

12. A method for generation and application of a magnetic field, the method comprising:

receiving sensor data;

generating a magnetic field in response to the sensor data; and

directly altering a flow of water through a trapway of a toilet using the magnetic field.

13. The method of claim 12 , wherein the magnetic field assists a flow of water through the trapway during a flush cycle.

14. The method of claim 12 , wherein the sensor data is indicative of at least one of a presence of a user, a water level in a bowl of the toilet, and a blockage in the trapway.

15. An apparatus for generation and application of a magnetic field in a toilet, the apparatus comprising:

a flexible sleeve; and

a magnet secured to the flexible sleeve and configured to generate a magnetic field, the magnetic field altering a flow of water through a trapway of a toilet.

16. The apparatus of claim 15 , wherein the magnet includes a series of permanent magnets.

17. The apparatus of claim 15 , further comprising:

a power source, and

wherein the magnet comprises an electromagnet powered by the power source.

18. The toilet of claim 1 , wherein the at least one magnet comprises a plurality of magnets disposed along a length of the trapway.

19. The method of claim 12 , wherein the magnetic field is generated by a plurality of magnets disposed along a length of the trapway.
