Abstract
An oven includes an oven chamber having a cavity at least partially defined by a door, a pair of side walls, and a rear wall; a baffle extending lengthwise between the pair of side walls, the baffle having an arcuate shape along at least a portion of its length; a heating element located between the baffle and the rear wall; and a first tangential fan configured to direct air over the heating element and through the baffle. The distance between the baffle and the rear wall is greater near the sidewalls than at the midpoint between the side walls.
Claims20
An oven comprising:
- an oven chamber having a cavity at least partially defined by a door, a top wall, a bottom wall, a pair of side walls, and a rear wall;
- a baffle mounted in the cavity between the pair of side walls, the baffle having an arcuate shape along a majority of its length between the pair of side walls;
- a heating element located between the baffle and the rear wall;
- and
- a first tangential fan comprising a first impeller mounted between the top wall and the bottom wall such that a first rotational axis of the first impeller is vertical, the first tangential fan configured to direct air over the heating element and through the baffle;
- wherein the distance between the baffle and the rear wall is greater near the side walls than at the midpoint between the side walls.
An oven comprising:
- a chamber having a cavity, the cavity defined at least partially by a rear wall, opposing sidewalls, a top wall, and a bottom wall, wherein the opposing sidewalls extend between the top wall and the bottom wall;
- a baffle mounted to and extending between the sidewalls and dividing the cavity into a front cavity and a rear cavity, the front cavity configured to receive foods for cooking, the baffle comprising a curved portion and a pair of planar portions provided on opposite sides of the curved portion;
- and
- a pair of tangential fans, each fan comprising an impeller that extends vertically between the top and bottom walls adjacent one of the sidewalls and within the rear cavity;
- wherein the tangential fans are configured to pull air from the front cavity into the rear cavity through the curved portion of the baffle, and direct the air from the rear cavity back into the front cavity through the planar portions of the baffle.
An oven comprising:
- an oven chamber having a cavity at least partially formed by a first side wall, a second side wall, a rear wall, and a door opposite the rear wall;
- a baffle extending between the first and second side walls and curved along a majority of its length in a horizontal direction between the first and second side walls;
- and
- a convection heat system comprising a first tangential fan and a second tangential fan, the first tangential fan located adjacent the interface of the rear wall and the first side wall, the second tangential fan located adjacent the interface of the rear wall and the second side wall, both the first and second tangential fans comprising an impeller that forms a vertical axis of rotation to produce an air flow toward the door along the respective sidewall.
