Patent number: 5562090Abstract: An oven door has a substantially vertical air passage through which air flows by convection. Air enters the air passage through air inlets at the bottom of a substantially rectangular decorative trim frame, which supports a front pane of glass, and the bottom of an inner liner to which the frame is attached. Air in the air passage flows over the substantially rectangular front pane of glass along its inner surface. The frame has air outlets, which are above the front pane of glass and communicate with the air passage to provide the only exit, to direct air substantially horizontally in the substantially horizontal plane of a handle assembly on the door. The frame has a baffle disposed within the air passage for deflecting air therefrom through the air outlets and over the handle gripping portion. The air passage is closed above the baffle, and stagnant air above the baffle functions as a heat insulator.Type: GrantFiled: July 22, 1993Date of Patent: October 8, 1996Assignee: General Electric CompanyInventor: Jonathan M.

Patent number: 5546927Abstract: The oven door comprises a frame on which two panes are mounted. These two panes are parallel and spaced apart from each other. The inside pane is hinge-mounted relative to the frame by means of a hinge piece and pivatable about a hinge axis at a lateral side of the frame. Rapid-action locking and unlocking closure means, that are point spacers, are situated remote from the hinge axis of the inside pane. The spacers enable the inside pane to be held in a closed position relative to the frame. The point spacers provide rapid-action locking and unlocking the closure, and keep a space between the inside pane and the inside face of the frame when the inside pane is closed. The hinge piece includes at least one plate. The inside pane is fixed at a distance from the plate by at least one fixing point spacer in such a manner that when the inside pane is in the closed position the plate engages and bears against the inside face of the frame.Type: GrantFiled: January 20, 1995Date of Patent: August 20, 1996Assignee: Eurofours S.A.Inventor: Pierre Lancelot

Patent number: 5471973Abstract: A gas fueled direct vent fireplace having a firebox within which flue gases are generated includes a glass face access door for closing the front of the fireplace and facing the interior of a room within which the fireplace is located. Flue gases exit remote from the front. A first seal is positioned about the periphery of the open front of the fireplace at locations accessible to flue gases for abutting the glass. A second seal is positioned about the periphery of the glass outwardly of the first seal so that only flue gases which leak past the first seal may contact the second seal. The first seal is formed from fiberglass which has high temperature characteristics. The second seal is formed from a silicone elastomeric material. With this arrangement leakage of hot gases into the adjoining room is substantially eliminated and the life of the elastomeric seal may be extended indefinitely relative to that of the prior art.Type: GrantFiled: January 5, 1995Date of Patent: December 5, 1995Assignee: Temco Fireplace Products, Inc.Inventor: Murray O.
