Composting device
A method of determining the volume of organic material in a composting device includes rotating a mixing paddle in a composting bin that stores the organic material; monitoring the torque from a motor that rotates the mixing paddle as the mixing paddle rotates; and determining the height of the organic material in the composting bin based on the motor torque and the angular displacement of the mixing paddle. The resulting height can be used to determine the volume of the organic material.
1. A composter comprising:
a housing;
a controller;
a composter bin defining a chamber configured to receive organic material;
a reducing mechanism comprising a rotatable shaft defining a horizontal direction with a first and second paddle extending radially from the rotatable shaft where the first paddle is longer than the second paddle; and
a motor providing a necessary torque to the reducing mechanism for rotating through the organic material;
wherein the controller is configured to determine an amount of the organic material in the composting bin based on the necessary torque provided and the first and second paddles rotate about the rotatable shaft.
2. The composter of claim 1 where the amount determined is a height and the height is converted to a volume with the controller.
3. The composter of claim 1 where the first and second paddles have different lengths.
4. The composter of claim 3 where the length of the first paddle or the second paddle corresponds to a zone representing a height of organic material through which the first or second paddle rotates.
5. The composter of claim 4 including different height zones representing varying heights of organic material.
6. The composter of claim 5 where each height zone further represents a volume of organic material.
7. The composter of claim 1 where the first paddle and the second paddle have different shapes.
8. The composter of claim 1 where at least one of the first paddle or second paddle is horizontally extended and angled in a vertical direction.
9. The composter of claim 7 where at least one of the first paddle or second paddle is in a curved shape.
10. The composter of claim 1 where the motor operates the first paddle at different speeds during a cycle of operation.
11. A composter comprising:
a composter bin having a chamber defining an upright cylinder defining a vertical direction with a hemispherical lower portion and configured to receive organic material;
a reducing mechanism comprising a rotatable shaft defining a horizontal direction with a first paddle extending radially the rotatable shaft and terminating in a curved end to match a contour of the hemispherical lower portion;
a motor providing a necessary torque to the reducing mechanism for rotating through the organic material; and
a controller configured to determine an amount of the organic material in the composting bin based on the necessary torque provided;
wherein the first paddle rotates about the rotatable shaft.
12. The composter of claim 11 wherein the amount determined is a height and the height is converted to a volume with the controller.
13. The composter of claim 11 wherein the reducing mechanism further includes a second paddle and the first and second paddles have different lengths.
14. The composter of claim 13 wherein the length of the first paddle or the second paddle corresponds to a zone representing a height of organic material through which the first or second paddle rotates.
15. The composter of claim 14 wherein the zone is multiple zones representing varying heights of organic material.
16. The composter of claim 11 wherein each zone further represents a volume of organic material.
17. The composter of claim 16 wherein at least one of the first paddle or second paddle is horizontally extended and angled in a vertical direction.
18. The composter of claim 11 wherein the reducing mechanism further includes a second paddle with a different dimension and shape than the first paddle.
19. The composter of claim 18 wherein the second paddle is in a curved shape.
20. The composter of claim 11 where the motor operates the first paddle at different speeds during a cycle of operation.
