Description

United States Patent O ice 3,270,736 BUILT-IN OVEN Eugene J. Barnett, Mansfield, Ohio, assigner to Westinghouse Electric Corporation, East Pittsburgh, Pa., a corporation of Pennsylvania Filed May 28, 1964, Ser. No. 371,051 3 Claims. (Cl. 126-19) The present invention relates to cooking ovens and more particularly to a -domestic cooking oven of the type adapted to be built into surrounding cabinet structures.

The popularity of the so-called built-in cooking oven is well established. Many of the oven arrangements now being built into the surrounding cabinet or wall structures of the modern kitchen are also provided with broiler facilities and problems have existed in connection with the -disposal of the heat vapors without damage to the surrounding Wall surfaces,

It is a principal object of the present invention to provide an improved arrangement of built-in oven construction having an extremely simple yet effective heat vapor deflector and heat insulating structure incorporated in the trim -adjacent the oven door.

Another object of the present invention is to provide an improved trim structure for the door of a built-in oven such 4that the surfaces of the trim members next adjacent the surrounding wall surfaces do not become heated enough to scorch or otherwise mar such Iwall surfaces.

In accordance with the invention the trim surrounding the oven door opening and in particular the door opening upper edge is comprised of a first planar heat deflecting ledge member having upper and lowr planar surfaces with its lower planar surface adjacent the upper edge of the door opening. The planar surfaces of the heat deflecting ledge extend outwards from the plane of the oven door in a manner to -deect heat vapors originating in the oven away from the surrounding cabinet wall surfaces near the plane of the oven door opening. A spacer panel of heat insulating material such as glass or decorative ceramic is positioned ywith a lower edge surface extending in Contact with the upper planar surface of the deflector ledge. The final upper or outer trim member of metal or the like which is in contact with the surrounding cabinet wall surfaces is supported from the lower deector ledge on spacers with the heat spacer panel floating therebetween. The provision of the spacer panel and the heat deflector ledge prevents the upper or outer trim member or the surrounding wall surfaces from being heated by either conduction or convection to a degree to cause discernible damage.

Further objects, features and the attendant advantages :of the invention will be apparent with reference to the following specification and drawing in which:

FIGURE 1 is a perspective elevation of a built-in oven With trim embodying the heat deflecting arrangements of the invention; and

FIG. 2 is a fragmentary detail on the line II--Il of FIG. 1.

Referring to the drawing, the oven cabinet liner, a fragment of which is shown at is arranged to be built into a surrounding wall or cabinet structure 4such as fragmentarily shown at 11. It will be noted that when the oven liner 10 is built into the surrounding wall 11', the plane of the oven door opening 12 is generally in the plane of the wall surface 11. As shown by FIG. 2 of the drawings, and particularly when the oven door is opened, heat vapors tend to rise from the oven adjacent the wall surface 11 but they are deflected by the planar heat deflector ledge 14 of the invention which extends across the upper edge surface or the door opening 12.

Of course, the heat deflector ledge 14 which is formed of any suitable material such as chromium plated metal 3,276,736 Patented Sept. 6, 1966 would become quite warm by contact with the oven liner 10 and the heat vapors from the ovenand in accordance with the invention a heat insulating panel 1-5 which may be formed of glass, decora-tive ceramic or other vitreous material is positioned with its lower edge surface 16 in contact with the upper planar surface of vthe heat detiector ledge 14. A final upper or outer trim molding 17 of any suitable material such as chromium plated metal is secured along the upper edge -surface 18 of the spacer panel 15 by means of the heat insulating spacer tubes 21 and pins 20 and is adapted to contact the surrounding wall surface 11 when the oven liner is built into the wall as shown.

The flow arrows of FIG. 2 show how the heat vapors are deflected `by the heat deector 14 to be mixed with relatively cooler surrounding air currents and to be dispersed generally away from the wall surface 11. Although the deflector ledge 14 may itself become heated, the spacer panel 15 of heat insulating material will prevent the outer trim member or molding 17 from becoming heated sufficiently to damage the wall surface.

As previously mentioned, the upper trim member 17 and the heat spacer panel 15 may be secured in place by one or more pins 20 extending through heat insulating spacer bushings 21 into retaining means such as the spring clip 22 on the oven liner 10 as shown. Rubber bushings or

cushions

23, 24 may also be provided to cushion the panel 15 in a oating arrangement such as to prevent breakage of the panel during shipment of the oven. The amount of heat conducted by the relatively small and few pins such as the pin 20 is immaterial. Of course the invention is not to be limited to a particular arrangement for securing the assembly such as the pin 20 and various other modifications will occur to those skilled in the art.

I claim as my invention:

1. An oven construction adapted to be built into a surrounding cabinet structure having a front wall surface and comprising, lan oven compartment liner adapted to be countersunk in said cabinet with an oven door opening in a plane substantially in alignment with said front wall surface, said door opening having an upper edge surface, a planar heat deflector ledge having upper and lower planar surfaces and positioned along the upper edge surface of said door opening with its planar surfaces extending outward from said door opening, a spacer panel of material having a relatively low thermal conductivity and comprising upper and lower edge surfaces and positioned with its lower edge surface above the upper planar surface of the ledge .and coextensive therewith, and a trim member extending along the upper edge surface of said panel and adapted to be in contact with the front wall surface of the surrounding cabinet.

2. An oven construction adapted to be built into a surrounding cabinet structure having a front wall surface and comprising, an oven compartment liner adapted to be countersunk in said cabinet with an oven door opening in a plane substantially in alignment with said front wall surface, said door opening having an upper edge surface, a planar heat deector ledge having upper and lower planar surfaces and positioned along the upper edge surface of said door opening with its planar surfaces extending outward from said door opening, a spacer panel of heat insulating ceramic material having upper and lower edge surfaces and positioned with its lower edge surface above the upper planar surface of the ledge and coextensive therewith, and a trim member extending along the upper edge surface of said panel and adapted to be in contact with the front wall surface of the surrounding cabinet.

3. An oven construction adapted to be built into a surrounding cabinet structure having .a front wall surface and comprising, an oven compartment liner adapted to be countersunk in said cabinet with an oven door opening in a plane substantially in .alignment with said `front wall surface, said `door opening having an upper edge surface, a planar heat deector ledge having upper and lower planar surfaces and positioned along the upper edge ysurface of said door opening with its planar surfaces extending outward from said door opening, a spacer panel of heat insulating vitreous material having upper and lower edge surfaces and positioned with its lower edge surface above the upper planar surface of the ledge and coextensive therewith, and a trim member extending along the upper edge surface of said panel and adapted to be in contact |with the front wall surface of the surrounding cabinet.
