Door and method of connecting components of a door for a cooking appliance
A door assembly for a cooking appliance includes an inner door assembly disposed adjacent a cooking cavity of the cooking appliance when the door assembly is in a closed position. An outer door assembly is coupled with the inner door assembly. The outer door assembly includes a panel. A skin bonds with the panel via an insulation arrangement disposed between the panel and the skin. The insulation arrangement includes a first adhesive that adheres the skin with a first surface of the insulation arrangement and a second adhesive that adheres the panel with a second surface of the insulation arrangement. A bonding feature extends from the skin to the panel to permanently bond the skin with the panel.
1 . A door for a cooking appliance, comprising:
an inner door assembly disposed adjacent a cooking cavity of the cooking appliance when the door is in a closed position; and
an outer door assembly coupled with the inner door assembly, the outer door assembly comprising:
a panel;
a skin bonding with the panel via an insulation arrangement disposed between the panel and the skin, the insulation arrangement including a first adhesive adhering the skin with a first surface of the insulation arrangement and a second adhesive adhering the panel with a second surface of the insulation arrangement; and
a bonding feature extending from the skin to the panel to permanently bond the skin with the panel, wherein the insulation arrangement defines a plurality of notches extending into an outer edge of the insulation arrangement, and wherein a portion of the bonding feature is disposed within each of the notches.
2 . The door of claim 1 , wherein the skin bonds with the panel via the insulation arrangement prior to curing of the bonding feature.
3 . The door of claim 1 , wherein the insulation arrangement includes an insulation layer having an aluminum backing.
4 . The door of claim 3 , wherein the first surface is disposed on the insulation layer and the second surface is disposed on the aluminum backing.
5 . The door of claim 1 , further comprising:
a backing plate coupled with the panel; and
an insulating substrate disposed between the backing plate and the panel.
6 . The door of claim 1 , wherein the bonding feature is room-temperature vulcanizing glue.
7 . The door of claim 6 , wherein first and second adhesives bond the skin with the panel while the bonding feature cures.
8 . The door of claim 7 , wherein a curing time of the bonding feature is greater than a curing time of the first and second adhesives.
9 . The door of claim 1 , wherein a first thickness of the bonding feature is at least a second thickness of the insulation arrangement.
10 . An outer door assembly for an oven, comprising:
a skin;
a panel disposed between a cooking cavity of the oven and the skin;
an insulation arrangement disposed between the panel and the skin, the insulation arrangement including an adhesive disposed on a surface of the insulation arrangement operably coupling the skin with the panel; and
a bonding feature at an outer edge of the insulation arrangement proximate notches defined in the insulation arrangement.
11 . The outer door assembly of claim 10 , wherein the insulation arrangement includes an insulation layer having an aluminum backing.
12 . The outer door assembly of claim 11 , wherein the adhesive is disposed on the insulation layer and the aluminum backing.
13 . The outer door assembly of claim 10 , further comprising:
a backing plate coupled with the panel; and
an insulating substrate disposed between the backing plate and the panel.
14 . The outer door assembly of claim 10 ,
wherein the bonding feature is separate from the adhesive and extends between the skin and the panel for permanently bonding the skin to the panel via a permanent bond formed after a curing time of the bonding feature.
15 . The outer door assembly of claim 14 , wherein the adhesive bonds the skin with the panel while the bonding feature cures.
16 . The outer door assembly of claim 14 , wherein the curing time of the bonding feature is greater than a curing time of the first and second adhesives.
17 . The outer door assembly of claim 14 , wherein a first thickness of the bonding feature is equal to or greater than a second thickness of the insulation arrangement.
18 . A method of assembling a door of an oven, comprising:
coupling an insulation arrangement with a skin of said door via a first adhesive disposed on a first surface of the insulation arrangement, the insulation arrangement defining a plurality of notches at an outer edge of the insulation arrangement;
applying a bonding feature adjacent the outer edge of the insulation arrangement to the skin adjacent the insulation arrangement for forming a permanent bond between the skin and a panel of said door when the panel engages the bonding feature, wherein the plurality of notches allow an area of the skin adhering to the insulation arrangement to be maximized to provide heat resistivity to said door; and
coupling the insulation arrangement with the panel via a second adhesive disposed on a second surface of the insulation arrangement, opposite the first surface, to bond the skin with the panel while the permanent bond cures.
