Abstract

A household cooking appliance including a housing having an oven chamber accessible through an opening, the opening having a seal surrounding a perimeter of the opening, and a door covering the opening and moveable about a hinge between an open position and a closed position. The door includes a full glass inner panel having an inner surface that abuts the seal when the door is in a closed position and shock-absorbing means for absorbing and distributing a shock or an impact on the full glass inner panel.

First claim

What is claimed is:

1. A household cooking appliance comprising:
a housing having an oven chamber accessible through an opening, the opening having a seal surrounding a perimeter of the opening; and
a door covering the opening and moveable about a hinge between an open position and a closed position, the door including:
an outer door skin comprising:
a front surface including an outer glass panel;
a first side surface;
a second side surface opposed to the first side surface;
an upper surface; and
a lower surface opposed to the upper surface;

a full glass inner panel forming a rear surface of the door and extending substantially from an edge of the first side surface to an edge of the second side surface and from an edge of the upper surface to an edge of the lower surface, the full glass inner panel having a front surface that faces toward a front of the door and a rear surface forming the rear surface of the door, wherein a portion of the rear surface of the full glass inner panel abuts the seal when the door is in a closed position; and
shock-absorbing means for resiliently and movably supporting the front surface of the full glass inner panel at a location of the front surface of the full glass inner panel that is spaced away from edges of the full glass inner panel, wherein the shock-absorbing means resiliently and movably support the front surface of the full glass inner panel such that the edges of the front surface of the full glass inner panel are maintained in a spaced position from firm surfaces of components of the door when the full glass inner panel moves in a direction toward the front of the door, wherein the shock-absorbing means absorb and distribute a shock or an impact on the full glass inner panel and prevent the front surface of the full glass inner panel from contacting the firm surfaces of the components of the door when the full glass inner panel moves in the direction toward the front of the door, and wherein the shock-absorbing means minimize heat transfer from the full glass inner panel to other heat conducting components of the door.

2. The household cooking appliance of claim 1 , wherein the shock-absorbing means include a flexible metal part resiliently and movably supporting the front surface of the full glass inner panel at the location of the front surface of the full glass inner panel that is spaced away from edges of the full glass inner panel, thereby maintaining a spaced position of the edges of the front surface of the full glass inner panel with respect to the edges of the first side surface, the second side surface, the upper surface, and the lower surface of the outer door skin when the full glass inner panel moves in the direction toward the front of the door.

3. The household cooking appliance of claim 2 , wherein the shock-absorbing means includes an insulation layer resiliently and movably supporting the front surface of the full glass inner panel with respect to the edges of the first side surface, the second side surface, the upper surface, and the lower surface of the outer door skin.

4. The household cooking appliance of claim 2 , wherein the shock-absorbing means further includes an insulation layer cooperating with the flexible metal part to resiliently and movably support the front surface of the full glass inner panel with respect to the edges of the first side surface, the second side surface, the upper surface, and the lower surface of the outer door skin.

5. The household cooking appliance of claim 1 , wherein the door further comprises:
means for movably retaining the rear surface of the full glass inner panel in a position adjacent to the edges of the first side surface, the second side surface, the upper surface, and the lower surface of the outer door skin without penetrating through the full glass inner panel.

6. The household cooking appliance of claim 5 , wherein the means for movably retaining includes:
a retaining lip extending across an edge of the upper surface of the door and retaining a top edge of the rear surface of the full glass inner panel.

7. The household cooking appliance of claim 6 , wherein the means for movably retaining further includes:
a hinge cover disposed adjacent to the hinge of the door, the hinge cover retaining a corner area of the rear surface of the full glass inner panel.

8. The household cooking appliance of claim 7 , wherein a perimeter of the full glass inner panel includes a cutout corresponding to the hinge and the hinge cover, wherein the hinge cover engages an edge of the rear surface of the full glass inner panel at the cutout to retain the full glass inner panel.

9. The household cooking appliance of claim 1 , wherein a perimeter of the full glass inner panel includes a first cutout at a first location corresponding to the hinge of the door.

10. The household cooking appliance of claim 9 , wherein a perimeter of the full glass inner panel includes a second cutout at a second location corresponding to a self-clean latch of the door, the self-clean latch configured to lock the door in the closed position during a self-cleaning process.

11. The household cooking appliance of claim 1 , wherein the door further comprises:
a middle glass panel disposed between the outer glass panel and the front surface of the full glass inner panel.

12. The household cooking appliance of claim 1 , wherein the full glass inner panel includes a transparent ceramic inner panel.

13. The household cooking appliance of claim 11 , wherein the shock-absorbing means is disposed between the location of the front surface of the full glass inner panel and the middle glass panel.

14. The household cooking appliance of claim 13 , wherein the shock-absorbing means includes a flexible metal part disposed between the location of the front surface of the full glass inner panel and the middle glass panel, the flexible metal part resiliently and movably supporting the front surface of the full glass inner panel with respect to the edges of the first side surface, the second side surface, the upper surface, and the lower surface of the outer door skin.

15. The household cooking appliance of claim 14 , wherein the shock-absorbing means includes a first insulation layer disposed between the front surface of the full glass inner panel and the middle glass panel, the first insulation layer surrounding a perimeter of the flexible metal part.

16. The household cooking appliance of claim 15 , wherein a part of the first insulation layer is disposed between the flexible metal part and the middle glass panel.

17. The household cooking appliance of claim 16 , wherein the door further comprises:
a hinge assembly disposed between the front surface of the full glass inner panel and the outer surface of the door skin; and
a second insulation layer disposed between the full glass inner panel and the hinge assembly.

18. The household cooking appliance of claim 17 , wherein the door further comprises:
deflectable insulation retaining means for moveably securing the second insulation layer to the hinge assembly between the front surface of the full glass inner panel and the hinge assembly.

19. The household cooking appliance of claim 18 , wherein the deflectable insulation retaining means includes a flexible metal retainer movable with respect to the hinge assembly in a direction normal to the front surface of the full glass inner panel.

20. The household cooking appliance of claim 14 , wherein the flexible metal part is suspended between the front surface of t
