Abstract
Abstract A pair of built-in wall ovens for household use is shown stacked one on the other. Each oven cooking cavity is vented toward the front wall of the oven to an area just above the oven door. Duct means are provided to direct the oven exhaust to the sides of the ovens away from the oven doors and the single control panel so as to hold down the maximum surface temperatures at the front of the ovens. Vertical exhaust stacks are arranged along the front corners of the oven bodies to collect the oven exhaust from the duct means and finally discharge it at the top of the stacks with a frontward discharge.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
103 words
A cooking oven comprising an oven body surrounding an oven cooking cavity formed by a box-like oven liner and a frontopening access door, the oven liner having an oven vent opening, first duct means connecting the oven vent opening to an area adjacent the front of the oven body at a location above the access door, said first duct means being connected to a second duct means extending to the side of the oven body, and an exhaust port means at the side of the oven body with a frontward discharge whereby the oven exhaust is substantially clear of the said access door.
Claim 2
Dependent Claim
103 words
A cooking oven comprising an oven body surrounding an oven cooking cavity formed by a box-like oven liner and a frontopening access door, the oven liner having an oven vent opening, first duct means connecting the oven vent opening to an area adjacent the front of the oven body at a location above the access door, said first duct means being connected to a second duct means extending to the side of the oven body, and an exhaust port means at the side of the oven body with a frontward discharge whereby the oven exhaust is substantially clear of the said access door.
Claim 3
Dependent Claim
43 words
A cooking oven as recited in claim 1 wherein the said second duct means extends to both Sides of the oven body and there is an exhaust port means at each side of the oven body, each port means having a frontward discharge.
Claim 4
Dependent Claim
57 words
A cooking oven as recited in claim 2 wherein the said second duct means is located above the top edge of the access door and incorporates an air channel means substantially coextensive therewith along the front portion thereof so as to restrict the temperature of the surfaces of the second duct means that are accessible to touch.
Claim 5
Dependent Claim
51 words
A cooking oven as recited in claim 3 wherein the said air channel means communicates with the exhaust port means at the sides of the oven body for mixing room ambient air with the oven exhaust and reducing the oven exhaust temperature before the exhaust discharges through the exhaust port means.
Claim 6
Dependent Claim
55 words
A cooking oven as recited in claim 4 with an oven control panel located at the front of the oven above both the said second duct means and the said air channel means carried thereby, the said exhaust port means directing the hot oven exhaust away from both the control panel and the oven door.
Claim 7
Dependent Claim
120 words
A cooking oven as recited in claim 5 with a second cooking oven stacked directly beneath the first said oven, the said oven control panel including control means for both ovens, the said lower oven having an oven exhaust system similar to that of the upper oven except for the exhaust port means at the side of the oven body, at least one exhaust stack extending up along the front corner of the oven bodies, the second duct means of the lower oven being connected into the said exhaust stack, the top portion of the exhaust stack being connected into the said exhaust port means, whereby the oven exhaust from both ovens may exit from the said exhaust port means.
Claim 8
Dependent Claim
67 words
A double oven as recited in claim 6 wherein there is an exhaust stack extending up along each front corner of the stacked oven bodies, whereby the exhaust from the lower oven passes into the second duct means for the lower oven and then rises up both exhaust stacks and then exits from the two exhaust port means at the two sides of the top oven body.
Claim 9
Dependent Claim
206 words
A cooking oven as recited in claim 5 with a second cooking oven stacked directly beneath the first said cooking oven, the said oven control panel including control means for both ovens, the said lower oven having an oven body surrounding an oven cooking cavity formed by a box-like oven liner and a front-opening access door, the oven liner of the lower oven having an oven vent opening, and first duct means connecting the last-mentioned oven vent opening to an area adjacent the front of the oven body at a location above the lower access door, said last-mentioned first duct means being connected to a second duct means extending to at least one side of the lower oven body, at least one exhaust stack extending up along a front corner of the two oven bodies, the second duct means of the lower oven being connected into the said exhaust stack, the top portion of the exhaust stack being connected into the said exhaust port means of the upper oven, whereby the oven exhaust from both ovens may exit from the said exhaust port means, the said exhaust stack being open to the atmosphere near the bottom thereof to increase the chimney effect within the exhaust stack.
Claim 10
Dependent Claim
64 words
A double oven construction as recited in claim 8 wherein there is an exhaust stack extending up along each front corner of the stacked oven bodies, whereby the exhaust from the lower oven passes into its second duct means and then uses up both exhaust stacks and then exits from the two exhaust port means at the two sides of the top oven body.
Claim 11
Dependent Claim
166 words
A double oven construction as recited in claim 9 wherein the said second duct means of the lower oven is located above the top edge of the lower access door and incorporates an air channel means substantially coextensive therewith along the front portion thereof so as to restrict the temperature of the surfaces of said last-mentioned second duct means that are within reach of a person''s touch, each of said exhauSt stacks being provided with a longitudinal partition to form a hot exhaust channel and a cool air channel, the two second duct means of both the upper and and lower ovens being connected to the hot exhaust channels of the two exhaust stacks, while the two air channel means of both the upper and lower ovens are connected to the cool air channels of the two exhaust stacks, the two channels of each exhaust stack being joined before the exhaust mixture discharges from the exhaust port means at each side of the upper oven body.
