Abstract

A method of operating a microwave appliance includes determining that a vent fan is on, and instructing an air handler within a door of the microwave appliance to operate in response to determining that the vent fan is on.

First claim

What is claimed is:

1. A method of operating a microwave appliance, the microwave appliance defining a vertical direction, a lateral direction, and a transverse direction and comprising a vent fan and a door assembly comprising an air handler positioned within the door assembly, the method comprising:
determining that the vent fan is on; and
instructing the air handler to operate at a high level in response to determining that the vent fan is on.

2. The method of claim 1 , further comprising:
determining that the vent fan is off after instructing the air handler to operate; and
instructing the air handler to cease operation at the high level in response to determining that the vent fan is off.

3. The method of claim 2 , wherein instructing the air handler to cease operation at the high level further comprises:
instructing the air handler to operate at a low power level.

4. The method of claim 1 , wherein determining that the vent fan is on comprises determining that the vent fan is activated at one of a high level or a low level.

5. The method of claim 1 , wherein the air handler comprises a plurality of axial fans spaced apart along the transverse direction.

6. The method of claim 1 , wherein the microwave appliance is mountable over a cooktop appliance.

7. The method of claim 1 , wherein the door assembly further comprises a monitor cradle mounted to the door frame and an image monitor mounted within the monitor cradle.

8. The method of claim 7 , wherein instructing the air handler to operate comprises:
urging a flow of air over a first panel side and a second panel side of the image monitor.

9. The method of claim 1 , wherein determining that the vent fan is on comprises detecting an input from a user to activate the vent fan.

10. The method of claim 1 , wherein the vent fan is turned on automatically by the microwave appliance.

11. A microwave appliance, the microwave appliance defining a vertical direction, a lateral direction, and a transverse direction, the microwave appliance comprising:
a cabinet defining a cooking chamber;
a vent fan provided within the cabinet;
a door assembly rotatably mounted to the cabinet for providing selective access to the cooking chamber, the door assembly comprising
a door frame defining a door plenum, an air inlet, a lower outlet, and an upper outlet,
a duct mounted to the door frame, and
an air handler positioned within the door frame for urging a flow of air through the door plenum; and

a controller provided in the microwave appliance and in communication with the vent fan and the air handler, the controller being configured to perform a series of operations, the series of operations comprising
determining that the vent fan is on; and
instructing the air handler to operate in response to determining that the vent fan is on.

12. The microwave appliance of claim 11 , wherein the series of operations further comprises
determining that the vent fan is off after instructing the air handler to operate, and
instructing the air handler to cease operation in response to determining that the vent fan is off.

13. The microwave appliance of claim 11 , wherein determining that the vent fan is on comprises determining that the vent fan is activated at one of a high level or a low level.

14. The microwave appliance of claim 11 , wherein the series of operations further comprises operating the air handler at a high level.

15. The microwave appliance of claim 11 , wherein the air handler comprises a plurality of axial fans spaced apart along the transverse direction.

16. The microwave appliance of claim 11 , wherein the microwave appliance is mountable over a cooktop appliance.

17. The microwave appliance of claim 11 , wherein the door assembly further comprises a monitor cradle mounted to the door frame and an image monitor mounted within the monitor cradle.

18. The microwave appliance of claim 17 , wherein instructing the air handler to operate comprises:
urging a flow of air over a first panel side and a second panel side of the image monitor.

19. The microwave appliance of claim 11 , wherein determining that the vent fan is on comprises detecting an input from a user to activate the vent fan.

20. The microwave appliance of claim 11 , wherein the vent fan is turned on automatically by the microwave appliance.
