Method and apparatus for cooling a user interface and/or door of a cooking device
View Patent ↗A cooking device includes a user interface having an outer surface. The user interface is connected to an outer enclosure. A duct is connected to the user interface. A door is connected to the outer enclosure. A cooling device is in thermal communication with a member selected from the group consisting of the outer surface and the door. The cooling device is connected to the user interface or the door by the duct.
1. A cooking device comprising:
an outer enclosure comprising at least a top, bottom, front wall, sidewalls and rear wall;
a cooking chamber disposed within said outer enclosure, wherein said outer enclosure further includes an opening in the front wall that enables access to said cooking chamber;
a door disposed about said opening and positioned below said top of said outer enclosure;
a user interface disposed about a front facing surface of said front wall of said outer enclosure above said door;
a cooling device that comprises:
an inlet disposed in said outer enclosure;
a conduit in communication with said inlet and said user interface; and
a fan in communication with said conduit, wherein said fan draws a cooling air from outside of said outer enclosure and through said conduit such that at least a portion of said cooling air contacts said user interface to remove heat from the user interface; and
at least one aperture disposed in a bottom facing surface of said front wall below said user interface substantially adjacent to a top surface of said door and in communication with said conduit such that said cooling air that exits said outer enclosure via said conduit and said at least one aperture after contacting said user interface, wherein said cooling air:
(i) contacts said top surface of said door when said door is in a closed position, and
(ii) forms an air curtain when said door is in an opened position.
2. The cooking device of claim 1 , wherein said airflow cools other members of said cooking device within said conduit.
3. The cooking device of claim 1 , wherein each of the at least one aperture in said bottom facing surface has an airflow of said cooling air through each of the at least one aperture to form said air curtain.
4. The cooking device of claim 1 , wherein the at least one aperture in said bottom facing surface forms said air curtain so that an airflow of hot air from said opening of said outer enclosure is directed away from said user interface.
5. The cooking device of claim 1 , wherein the at least one aperture in said bottom facing surface is uncovered when said door is in said opened position.
6. The cooking device of claim 5 , wherein said air curtain directs heat and/or steam generated within said cooking chamber away from said user interface when said door is in said opened position.
7. The cooking device of claim 1 , wherein said cooling device comprises said fan that generates an airflow of the cooling air in a first space between said cooking chamber and said outer enclosure, and wherein said airflow flows in a second space between said fan and said door, and wherein said fan is in fluid communication with a passageway around said door when said door is in said closed position.
8. The cooking device of claim 1 , wherein said air curtain is directed toward said door.
9. The cooking device of claim 7 , wherein said passageway directs said airflow around a surface of said door within said outer enclosure.
10. The cooking device of claim 4 , wherein said user interface is connected to said outer enclosure directly above said one or more holes.
11. A cooking device comprising:
an outer enclosure comprising at least a top, bottom, front wall, sidewalls and rear wall;
a cooking chamber disposed within said outer enclosure, wherein said outer enclosure further includes an opening in the front wall that enables access to said cooking chamber;
a door disposed about said opening and positioned below said top of said outer enclosure;
a user interface disposed about a front facing surface of said front wall of said outer enclosure above said door; and
a cooling device that comprises:
an inlet disposed in said outer enclosure;
a conduit in communication with said inlet and said user interface; and
a fan in communication with said conduit, wherein said fan draws a cooling air from outside of said outer enclosure and through said conduit such that at least a portion of said cooling air contacts said user interface to remove heat from the user interface; and
at least one aperture disposed in a bottom facing surface of said front wall below said user interface substantially adjacent to a top surface of said door and in communication with said conduit such that said cooling air that exits said outer enclosure via said conduit and said at least one aperture after contacting said user interface, wherein said cooling air forms an air curtain to deflect away at least a portion of a heated air of the cooking chamber from contacting an outer surface of said user interface when said door is in an opened position.
12. The cooking device of claim 11 , wherein each of the at least one aperture in said bottom facing surface of said top of said outer enclosure has an airflow of said cooling air through each of the at least one aperture to form said air curtain.
13. The cooking device of claim 11 , wherein said the at least one aperture in said bottom facing surface of said top of said outer enclosure forms said air curtain so that an airflow of said cooling air and hot air from said opening of said outer enclosure is directed away from said user interface.
14. The cooking device of claim 11 , wherein said the at least one aperture in said bottom facing surface of said top of said outer enclosure is uncovered when said door is in said opened position.
15. The cooking device of claim 11 , wherein said air curtain directs heat and/or steam generated within said cooking chamber away from said user interface when said door is in said opened position.
16. The cooking device of claim 11 , wherein said cooling device comprises said fan that generates an airflow of the cooling air in a first space between said cooking chamber and said outer enclosure, and wherein said airflow flows in a second space between said fan and said door, and wherein said fan is in fluid communication with a passageway around said door when said door is in said closed position.
17. The cooking device of claim 16 , wherein said passageway directs said airflow around a surface of said door within said outer enclosure.
