Abstract

A double oven combination is configured to be “built-in” an area of a household—in other words, permanently secured relative to the household area and integrated with other elements of the household area to provide a consistent decorative appearance. The double oven combination comprises an upper oven and a lower oven each of which may be a convection or non-convection oven that cooks and heats food and other substances via radiant and convective heating, and a control panel. The double oven combination has an integrated cooling air and exhaust air flow arrangement for efficiently guiding exhaust air away from the upper oven and the lower oven while at the same time effectively flowing cooling air relative to the double oven combination to promote desired cooling of the double oven combination.

Claims

1. An integrated cooling air and exhaust air flow arrangement for influencing the heat dissipation of a double oven combination formed of two ovens arranged with one oven above and relatively proximate to the other oven, the double oven combination adapted to be installed into an area of a structure, the integrated cooling air and exhaust air flow arrangement comprising:

a first air guiding path for guiding a mixture of cooling air and air that has been exhausted from the upper oven downwardly to a base channel extending below the lower oven;

a second air guiding path for guiding a mixture of cooling air and air that has been exhausted from the lower oven downwardly to the base channel extending below the lower oven, the second air guiding path including a mid-channel formed above the lower oven and below the upper oven with cooling air entering the mid-channel from outwardly of the upper and lower ovens and mixing in the mid-channel with heated air that has exited a top portion of an oven door that selectively closes and permits access to an access opening of an oven cavity of the lower oven; and

a latch plate shield located above the access opening of the oven cavity of the lower oven and below the upper oven, the latch plate shield being cooperatively configured with respect to the top portion of the oven door of the lower oven for influencing heated air exiting the top portion of the oven door to enter the mid-channel of the second air guiding path and latch plate shield assembly including at least one cooling air aperture for the entry of cooling air into the mid-channel of the second air guiding path, whereby the integrated cooling air and exhaust air flow arrangement efficiently guides exhaust air away from the upper oven and the lower oven while at the same time effectively flowing cooling air relative to the double oven combination to promote desired cooling of the double oven combination and the latch plate shield includes a protruding bill element that protrudes outwardly in the direction toward the area of the structure in which the double oven is installed, the protruding bill element including an underside extent and a topside extent that together form an outermost edge that extends nearly to an inside surface of the oven door of the lower oven when the oven door is in its oven cavity closing disposition, and the protruding bill element includes a plurality of underside apertures formed on the underside extent of the protruding bill element.

2. The integrated cooling air and exhaust air flow arrangement according to claim 1, wherein the latch plate shield includes a plurality of door air receipt apertures formed in the latch plate shield below the protruding bill element, a latch hook through hole formed longitudinally centrally in the latch plate shield below the protruding bill element, and a plurality of cooling air entry apertures formed above the protruding bill element.
