Heat distribution member and vents for toaster oven
A heating appliance includes a housing defining a food product compartment having at least a front door and a rear wall opposite the front door. The heating appliance also includes a rack configured to support a food product within the food product compartment. The heating appliance also includes a heating assembly disposed within the food product compartment and an elongate heating device having a first length, and an angled heat distribution member having a second length disposed between the heating device and the rack. The heat distribution member includes a pattern of apertures and the heat distribution member is configured to prevent infrared radiation produced by the heating device from directly reaching the rear wall of the housing, except for infrared radiation that passes through the apertures of the heat distribution member.
1. A heating appliance, comprising:
a housing defining a food product compartment having at least a front door and a rear wall opposite the front door;
a rack operatively positionable to the housing to support a food product within the food product compartment;
a heating device operatively connected with the housing and disposed within the food product compartment, the heating device positioned to heat air within the food product compartment thus causing the heated air to rise within the food product compartment;
a first air vent located at a lower portion of the rear wall of the housing, the first air vent permitting fluid communication between the food compartment and an outside of the housing through the rear wall, so that when the heating device is energized for causing the heated air to rise, additional air is drawn from the outside of the housing through the first air vent into the food product compartment toward the heating device; and
a second air vent located at an upper portion of the rear wall of the housing, the second air vent permitting fluid communication between the food compartment and the outside of the housing through the rear wall, so that when the heating device is energized for causing the heated air to rise, the heated air is caused to circulate within the food compartment with at least some of the air exiting the food product compartment through the second air vent.
2. The heating appliance of claim 1 , wherein the heating device is positioned at a height between a height of the first air vent and a height of the second air vent.
3. The heating appliance of claim 1 , wherein the first air vent includes a first air vent array having two or more air vents, and wherein the second air vent includes a second air vent array having two or more air vents.
4. The heating appliance of claim 1 , wherein the rear wall includes a plurality of sections,
wherein the first and second air vents are both located in a middle section as between side edges of the rear wall with the first vent located in a bottom section as between top and bottom edges of the rear wall, and with the second vent located in a top section as between the top and bottom edges of the rear wall.
5. A method of heating air within an oven, comprising;
generating heat using a heating device located within a food product compartment of the oven;
heating the air using the heat generated by the heating device, causing the heated air to rise within the food product compartment;
drawing in outside air at a first air vent located on a lower portion of a rear wall of a housing of the oven, the first air vent permitting fluid communication through the rear wall; and
circulating the rising, heated air in a first circulation path with at least some of the heated air exiting the oven housing through a second air vent located on an upper portion of the rear wall of the oven housing, the second air vent permitting fluid communication through the rear wall.
6. The method of claim 5 , further comprising:
defining the food product compartment of oven with a front door located opposite the rear wall.
7. The method of claim 6 , wherein the circulating causes the first circulation path to be generally closer to the rear wall than the front door.
8. The method of claim 6 , wherein the circulating further causes the heated air to circulate in a second circulation path that is generally closer to the front door than the rear wall.
9. The method of claim 5 , wherein the heat generated by the heating device is convective heat.
