Abstract
A self-contained window unit adapted to be assembled into an oven door, having three glass panes and a microwave shield. Two of the glass panes are held in spaced parallel relation by a frame of electrically-conducting material which has a peripheral mounting flange in electrical contact with the edge of the microwave shield. The third pane is secured to the frame by a plurality of individual mounting clips. Fasteners around the four sides of the window unit secure the mounting flange to the door to both mount the window unit and ground the microwave shield.
Claims20
A self-contained window unit adapted to be assembled into an oven door having front and back panels with aligned window openings therein and means defining an air passage to allow air to flow upwardly through the door and window unit therein, comprising a window sub-assembly having a pair of glass panes, means to hold said panes in spaced parallel relation, a third glass pane, and means for securing said third glass pane to said window sub-assembly in a position at one side thereof and in spaced parallel relation to the adjacent glass pane of said sub-assembly, said securing means providing areas between said third pane and said adjacent pane of said sub-assembly at the top and bottom of said window unit defining an opening adapted to communicate with the air passage in the door to allow the air to flow upwardly therebetween, said holding means comprising a frame of electrically-conducting material extending about the peripheries of said pair of panes and having a mounting flange, a microwave shield having an edge portion in surface-to-surface electrical contact with said flange, and means for securing said flange to one of said door panels to mount said window unit and ground said shield.
A self-contained window unit adapted to be assembled into an oven door having front and back panels with aligned window openings therein and means defining an air passage to allow air to flow upwardly through the door and window unit therein, comprising a window sub-assembly having a pair of glass panes, means to hold said panes in spaced parallel relation, a third glass pane, and means for securing said third glass pane to said window sub-assembly in a position at one side thereof and in spaced parallel relation to the adjacent glass pane of said sub-assembly, said securing means providing areas between said third pane and said adjacent pane of said sub-assembly at the top and bottom of said window unit defining an opening adapted to communicate with the air passage in the door to allow the air to flow upwardly therebetween, said holding means comprising a frame of electrically-conducting material extending about the peripheries of said pair of panes and having a mounting flange, a microwave shield extending parallel to said pair of panes and having an edge portion overlying said mounting flange, and means for clamping said edge portion of said shield and said flange together and for securing said flange to one of said door panels to both mount said window unit and ground said microwave shield.
An oven door having front and back panels with aligned window openings therein and means defining an air passage to allow air to flow upwardly through the door, a self-contained window unit mounted in said door between said panels in register with the openings therein including a window sub-assembly having a pair of glass panes, means to hold said panes in spaced parallel relation, a third glass pane, means for securing said third glass pane to said window sub-assembly in a position at one side thereof and in spaced parallel relation to the adjacent glass pane of said sub-assembly, said securing means providing areas between said third pane and said adjacent pane of said sub-assembly at the top and bottom of said window unit defining an opening adapted communicate with the air passage in the door to allow the air to flow upwardly therebetween, and a fourth glass pane mounted on one of the door panels in register with the window opening therein and in spaced relation to said third glass pane to provide an opening therebetween communicating with the air passage in the door to allow the air to flow upwardly therethrough.
The self-contained window unit defined in claim 15, wherein said securing means for said third glass pane comprises a plurality of spaced mounting clips.
