Abstract

A microwave oven includes a top wall, side walls, and a bottom wall at least partially defining a cavity of the microwave oven, and a table coupled to the bottom wall. The table has a top surface and an opposing bottom surface. The top surface is configured to support an item within the cavity. A light source directs light to the table. The table is configured to diffuse light emitted from the light source into the cavity.

Claims (15)

1. A microwave oven comprising:

a top wall, side walls, and a bottom wall at least partially defining a cavity of said microwave oven, the bottom wall defining an aperture therethrough;

a table coupled to the bottom wall, the table having a top surface and an opposing bottom surface, the top surface configured to support an item within said cavity;

a mixer defining a mixing chamber formed in part by a bottom portion, the bottom portion defining a plurality of light directing surfaces extending outwardly therefrom, the mixing chamber defined in part by a plurality of channels, a longitudinal axis of each channel being aligned to intersect with one of the plurality of light directing surfaces, the mixing chamber further defining an outlet aligned with the aperture in the bottom wall of the microwave oven;

a plurality of light sources, each light source positioned within or adjacent an outer end of each of the plurality of channels; and

the mixer configured to allow light from the light sources to pass through the corresponding channels towards the light directing surface and reflect through the outlet through said table, said table configured to diffuse the light emitted from said plurality of light sources into said cavity to illuminate said cavity.

2. A microwave oven in accordance with claim 1 , wherein said light source comprises a light-emitting diode.

3. A microwave oven in accordance with claim 1 , wherein said table comprises at least one central light directing surface aligned with said outlet; said at least one central light directing surface configured to direct light from said light source toward a peripheral edge of said table.

4. A microwave oven in accordance with claim 1 , wherein said mixer further comprises:

a top portion comprising said outlet; and

side portions positioned between said bottom portion and said top portion, said side portions at least partially defining side walls of said plurality of channels.

5. A microwave oven in accordance with claim 1 further comprising a light pipe positioned within said outlet and configured to direct light from said mixer through said outlet.

6. A microwave oven in accordance with claim 1 , wherein the table further comprises at least one light directing surface defined between said top surface and said bottom surface, said at least one light directing surface configured to direct light from the plurality of light sources through said top surface.

7. A microwave oven in accordance with claim 6 , wherein said at least one light directing surface comprises a peripheral light directing surface that at least partially circumscribes a peripheral edge of said table and is configured to direct light upwardly from the peripheral edge.

8. A microwave oven in accordance with claim 1 , wherein the table comprises at least one of acrylic, optically clear glass, and polycarbonate.
