Abstract

A method and apparatus for operating a food waste recycling appliance includes a food waste recycling container, a condensate reservoir, a first fluid pathway fluidly coupling the food waste recycling chamber and the condensate reservoir, and a fan moving air from the food waste recycling chamber to the condensate reservoir along the first fluid pathway to define a first airflow.

First claim

What is claimed is:

1. A food waste recycling appliance comprising:
a housing defining an interior;
a recycling chamber located within the interior and configured to receive organic material for recycling;
a reducing mechanism provided within the recycling chamber and configured to mix the organic material with air;
a container configured to receive the recycled organic material from the recycling chamber;
a condensate reservoir located within the interior of the housing and fluidly coupled to the recycling chamber; and
a plurality of biocidal agents disposed in the condensate reservoir, each of the plurality of biocidal agents having a plurality of filaments intertwined with each other to form a matrix in three dimensions, wherein each of the plurality of filaments comprises a surface of exposed copper.

2. The food waste recycling appliance of claim 1 wherein each of the plurality of filaments are copper wires.

3. The food waste recycling appliance of claim 1 wherein each of the plurality of filaments are covered by copper.

4. The food waste recycling appliance of claim 1 further comprising an air flow conduit in communication with the condensate reservoir.

5. The food waste recycling appliance of claim 1 wherein each of the plurality of biocidal agents is substantially cylindrical and has a diameter of about 80.4 mm and a height of about 31.1 mm.

6. The food waste recycling appliance of claim 1 wherein each of the plurality of biocidal agents has about 99.9 percent by weight of elemental copper.

7. The food waste recycling appliance of claim 1 wherein the condensate reservoir has a drain, and each of the plurality of biocidal agents is dimensioned to avoid blocking the drain.

8. A method of treating liquid in a condensate reservoir in a food waste recycling appliance, the method comprising:
operating a reducing mechanism within a chamber of the food waste recycling appliance containing organic material to generate moisture;
flowing the moisture from the chamber;
converting the moisture to condensate and storing the condensate within the condensate reservoir;
exposing a plurality of biocidal agents to the condensate within the condensate reservoir, each of the plurality of biocidal agents having a plurality of filaments intertwined with each other to form a matrix in three dimensions, wherein each of the plurality of filaments comprises a surface of exposed copper; and
maintaining liquid in the condensate reservoir with the plurality of biocidal agents, wherein the copper inhibits growth of life forms in liquid in the reservoir.

9. The method of claim 8 wherein each of the plurality of filaments are copper wires.

10. The method of claim 8 wherein each of the plurality of filaments are covered by copper.

11. The method of claim 8 further comprising flowing air into the water-condensate reservoir.

12. The method of claim 8 wherein each of the plurality of biocidal agents is substantially cylindrical and has a diameter of about 80.44 mm and a height of about 31.1 mm.

13. The method of claim 8 wherein each of the plurality of biocidal agents has about 99.9 percent by weight of elemental copper.

14. The method of claim 8 wherein the condensate reservoir has a drain, and each of the plurality of biocidal agents is dimensioned to avoid blocking the drain.
