Abstract

A cooking oven includes a housing defining an internal cooking cavity with an opening. A door assembly includes an inner panel framing an inner glass pane, and an outer panel framing an outer glass pane. A pivot arrangement pivotably mounts the door assembly to the housing. The pivot arrangement includes at least one pivot part located on the door assembly and at least one pivot part located on the housing. The pivot part of the door assembly is separable from the pivot part of the housing via vertically upward movement of the door assembly and upon separation of the pivot part of the door assembly from the pivot part of the housing the door becomes completely removed from the housing to enable the door assembly to be taken to a washing station for cleaning.

First claim

What is claimed is:

1. A cooking oven, comprising:
a housing defining an internal cooking cavity with an opening for enabling food items to be moved into and out of the cooking cavity;
a door assembly including an inner panel framing an inner glass pane, an outer panel framing an outer glass pane that is spaced apart from the inner glass pane;
a pivot arrangement that pivotably mounts the door assembly to the housing for permitting movement of the door assembly about a vertical pivot axis between a closed position and an open position relative to the cooking cavity, the pivot arrangement including at least one pivot part located on the door assembly and at least one pivot part located on the housing;
wherein the pivot part of the door assembly is separable from the pivot part of the housing via vertically upward movement of the door assembly and upon separation of the pivot part of the door assembly from the pivot part of the housing the door becomes completely removed from the housing to enable the door assembly to be taken to a washing station for cleaning;
wherein the door assembly includes a plurality of openings that permit fluid to enter a space between both the inner panel and the outer panel and the inner glass pane and the outer glass pane during cleaning of the door assembly such that the fluid can contact an inner surface of the inner glass pane and an inner surface of the outer glass pane for cleaning;
wherein the door assembly includes an inner skin an outer skin;
the inner skin comprises the inner panel and at least one flange, the flange having multiple openings therein;
the outer skin comprises the outer panel and at least one flange, the flange of the outer skin having multiple openings therein;
wherein the inner skin is assembled with the outer skin such that the flange of the inner skin overlaps with the flange of the outer skin, with the openings of the respective flanges aligned to provide fluid access to the space between both the inner panel and the outer panel and the inner glass pane and the outer glass pane;
wherein the door assembly further includes a frame component extending along top, bottom and side portions of the door assembly, the frame component including a frame segment with a plurality of openings therein that align with the aligned openings of the respective flanges of the inner skin and the outer skin.

2. The cooking oven of claim 1 wherein the inner skin, outer skin and frame component are secured together by multiple fasteners.

3. The cooking oven of claim 1 wherein the pivot part of the door assembly is a female member and the pivot part of the housing is a male member.

4. A cooking oven, comprising:
a housing defining an internal cooking cavity with an opening for enabling food items to be moved into and out of the cooking cavity;
a door assembly including an inner skin with a first opening covered by an inner glass pane, an outer skin with a second opening covered by an outer glass pane, the inner skin and the outer skin connected together to hold the inner glass pane and outer glass pane in an aligned but spaced apart relationship;
a pivot arrangement that pivotably mounts the door assembly to the housing for permitting movement of the door assembly about a vertical pivot axis between a closed position and an open position relative to the cooking cavity, the pivot arrangement including at least one pivot part fixed to the door assembly and at least one pivot part fixed to the housing;
wherein the pivot part of the door assembly is separable from the pivot part of the housing via vertically upward movement of the door assembly and upon separation of the pivot part of the door assembly from the pivot part of the housing the door becomes removed from the housing to enable the door assembly to be taken to a washing station for cleaning;
wherein the door assembly includes a plurality of openings that permit fluid to enter a space between both the inner skin and outer skin and the inner glass pane and the outer glass pane during cleaning of the door assembly such that the fluid can contact an inner surface of the inner glass pane and an inner surface of the outer glass pane for cleaning;
wherein the inner skin comprises an inner panel and at least an upper flange and a lower flange, the inner panel framing the first opening, each of the upper flange and the lower flange including multiple openings therein;
wherein the outer skin comprises an outer panel and at least an upper flange and a lower flange,the outer panel framing, the second opening, each of the upper flange and the lower flange including multiple openings therein;
wherein the inner skin is assembled with the outer skin such that the upper flange of the inner skin overlaps with the upper flange of the outer skin with the openings of each upper flange aligned, and the lower flange of the inner skin overlaps with the lower flange of the outer skin with the openings of each lower flange aligned.

5. The cooking oven of claim 4 wherein:
the door assembly further includes a frame component extending along top, bottom and side portions of the door assembly, the frame component including an upper frame segment with a plurality of openings therein that align with the aligned openings of the upper flanges, the frame component including a lower frame segment with a plurality of openings therein that align with the aligned openings of the lower flanges.

6. The cooking oven of claim 5 wherein the inner skin, outer skin and frame component are secured together by multiple fasteners.

7. The cooking oven of claim 5 wherein:
the inner skin includes first and second side flanges;
the outer skin includes first and second side flanges;
the frame component includes first and second side frame segments;
the first side flange of the inner skin, first side flange of the outer skin and first side frame segment are positioned in a stacked manner;
the second side flange of the inner skin, second side flange of the outer skin and second side frame segment are positioned in a stacked manner.

8. The cooking oven of claim 4 wherein:
the inner skin includes first and second side flanges;
the outer skin includes first and second side flanges;
the door assembly further includes a frame component extending about top, bottom and side portions of the door assembly, the frame component including an upper frame segment, a lower frame segment a first side frame segment and a second side frame segment,
the upper, lower, first side and second side frame segments of the frame component are located respectively inward of and adjacent to the upper, lower, first side and second side flanges of the inner skin;
the upper, lower, first side and second side flanges of the inner skin are located respectively inward of and adjacent to the upper, lower, first side and second side flanges of the outer skin.

9. The cooking oven of claim 8 wherein the upper fame segment includes a plurality of openings therein that align with the aligned openings of the upper flanges, the lower fame segment includes a plurality of openings therein that align with the aligned openings of the lower flanges.

10. The cooking oven of claim 9 wherein the inner skin, outer skin and frame component are secured together by multiple fasteners.

11. The cooking oven claim 4 wherein the pivot part of the door assembly is a female member and the pivot part of the housing is a male member.

12. A method of using the oven of claim 1 , comprising:
