Abstract

A method and apparatus for operating a composter device includes a compost container, a condensate reservoir, a first fluid pathway fluidly coupling the composting chamber and the condensate reservoir, and a fan moving air from the composting chamber to the condensate reservoir along the first fluid pathway to define a first airflow.

First claim

What is claimed is:

1. A composter comprising:
a compost container defining a composting chamber;
a condensate reservoir;
a first fluid pathway fluidly coupling the composting chamber and the condensate reservoir;
a second fluid pathway coupling ambient air and the condensate reservoir and in heat transfer juxtaposition with the first fluid pathway; and
a fan moving air from the composting chamber to the condensate reservoir along the first fluid pathway to define a first airflow and moving ambient air to the condensate reservoir along the second fluid pathway to define a second airflow;
wherein the second fluid pathway is fluidly isolated from the first fluid pathway, and the first and second airflows mix in the condensate reservoir.

2. The composter of claim 1 wherein the fan is downstream from the condensate reservoir.

3. The composter of claim 2 wherein the fan is a suction fan that generates a low pressure to draw air along the first fluid pathway and along the second fluid pathway.

4. The composter of claim 1 wherein the second fluid pathway includes a controllable valve that selectively provides ambient air along the second fluid pathway.

5. The composter of claim 4 further including at least one of a temperature sensor or a humidity sensor located proximate to the compost container.

6. The composter of claim 5 further including a controller communicatively coupled with the controllable valve and configured to operate the controllable valve based on the at least one of the temperature sensor or humidity sensor.

7. The composter of claim 1 further including a heat exchanger positioned along the first fluid pathway between the composting chamber and the condensate reservoir to reduce the temperature of the first airflow.

8. The composter of claim 7 wherein the heat exchanger is exposed to the ambient air along the second fluid pathway such that at least a portion of the heat removed from the first airflow is transferred to the ambient air.

9. The composter of claim 7 wherein the first fluid pathway further includes a liquid pathway between the heat exchanger and the condensate reservoir to deliver condensate to the condensate reservoir.

10. The composter of claim 1 further including a composter housing and the second fluid pathway includes at least a porous portion of the composter housing allowing ambient air external to the composter housing to flow along the second airflow to an interior of the composter housing.

11. The composter of claim 1 further including a third fluid pathway fluidly venting the condensate reservoir to the ambient air to define a third airflow.

12. The composter of claim 11 wherein the third airflow has a relative humidity less than 60 percent.

13. A composter comprising:
a compost container defining a composting chamber;
a condensate reservoir;
a first fluid pathway fluidly coupling the composting chamber and the condensate reservoir;
a second fluid pathway coupling ambient air and the condensate reservoir and crossing the first fluid pathway;
a heat exchanger positioned in-line with the first fluid pathway and the second fluid pathway and transferring heat from the first fluid pathway to the second fluid pathway; and
a fan moving air from the composting chamber to the condensate reservoir along the first fluid pathway to define a first airflow and moving ambient air to the condensate reservoir along the second fluid pathway to define a second airflow;
wherein the second fluid pathway is fluidly isolated from the first fluid pathway, and the first and second airflows mix in the condensate reservoir.
