Abstract

A broiling oven formed by an oven liner and an access door. Two electric radiant heating elements are located beneath the top wall of the oven liner. A hinged reflective plate is supported at each side of the innermost heating element. When these plates are lowered they form a miniature broiling compartment using the innermost heating element. When they are raised both heating elements may be operated together or separately.

Claims

1. A broiling oven comprising an oven cooking cavity formed by a box-like oven liner and an access door, radiant heating means fixed substantially horizontally adjacent a top wall of the oven liner, an oven shelf for supporting food to be cooked thereon, and means for supporting the oven shelf in the top portion of the oven liner, below said heating means an adjustably mounted reflective means at each side of the heating means, each reflective means having a first downward position for forming with the other reflective means a miniature boiling compartment with relation to the said oven shelf and any food that may be placed thereon, so the food is adapted to be located between the two reflective means, and below said heating means the reflective means having a second raised position which enables the radiant heating means to radiate througout much of the oven cooking cavity.

2. A broiling oven as recited in claim 1 wherein the said radiant heating means includes an inner and an outer heating element of looped configuration, the said adjustably mounted reflective means being hingedly supported between the inner and the outer heating elements, and control means for the two heating elements so that only the inner heating element is energized when the reflective means are positioned in their first downward position to form the miniature broiling compartment so as to conserve heating energy by improving the efficiency of broiling small portions of food and using lower powered heaters.

3. A broiling oven as recited in claim 2 wherein the reflective means "overlap the outer heating element in their raised position and each of the reflective means" is provided with aperture means aligned with a portion of the outer heating element when the reflective means is in its second raised position so as to permit the radiant energy of the outer heating element to transmit downwardly through the aperture means and throughout the oven cooking cavity, said control means serving to energize both the inner and the outer heating element when broiling in the overall oven cooking cavity.

4. A broiling oven as recited in claim 3 with the addition of manually adjustable support means for holding the reflective means in the second raised position, and means for releasing the said support means to permit the reflective means to move to the first downward position.

5. A broiling oven as recited in claim 1 with a fixed reflector means mounted between the said radiant heating means and the top wall of the oven liner, the said adjustably mounted reflective means being hinged to opposing sides of said reflector means, whereby the said miniature broiling compartment is formed by the combination of the said reflector means and the two adjustably mounted reflective means when they are positioned in their first downward position with the food being located therebetween.

6. A broiling oven as recited in claim 5 wherein the said radiant heating means includes an inner and an outer heating element of looped configuration, the said reflector means being mounted above the inner heating element and said reflective means being bingedly supported between the inner and outer heating elements, and control means for the two heating elements so that only the inner heating element is energized when the reflective means are positioned in their first downward position so as to improve the efficiency of broiling small amounts of food

7. A broiling oven as recited in claim 6, wherein the said reflective means overlap the outer heating element in their raised position and are provided with aperture means aligned with a portion of the outer heating element when the reflective means are in their second raised position so the energy of the outer heating element may radiate downwardly over a wide area.

8. A broiling oven as recited in claim 5 wherein each of said reflective means is formed integrally with an elongated hinging means that joins the reflective means to the said reflector means, said hinging means having a handle portion which may be locked with relation to the reflector means when the reflective means is in its second raised position for supporting the reflective means, and means for releasing the handle from its locked position for lowering the reflective means into the first downwardly position.

9. A broiling over as recited in claim 5 with the addition of manually adjustable support means cooperating with the said reflector means, said support means being extendible to engage the reflective means and pivot them up to the second raised position, said support means also being retractible for releasing the reflective means and allowing them to assure their first downward position.

10. A broiling oven as recited in claim 9 wherein the said manually adjustable support means includes an operating handle means which extends outwardly of the oven liner so that the reflective means may be adjusted from outside the oven.
