Abstract:
A cooking oven comprising a housing, a cavity, an oven door, an air plenum, an infrared heating element, and a thermal insulating layer placed between the infrared heating element and the air plenum is disclosed. The infrared hearing element comprises a wire-like heating element shaped in a serpentine-pattern to form a plurality of fingers. The thermal insulating layer comprises a plurality of air channels interconnecting the air plenum and the cavity, and one or more temperature decoupling chambers for thermally insulating the air plenum from the infrared heating element. The air channels are positioned interleavingly between the plurality of fingers so that airstreams coming from the air plenum through each of the air channels into the cavity do not substantially contact and convectively cool the infrared heating element. The temperature decoupling chambers may use air as a thermal insulator.
Abstract:
An oven comprising a housing, a cavity located within the housing, and a rotator having a first food loading section and a second food loading section is disclosed. The cavity includes a single opening for loading a food item into the cavity. If one of the first food loading section and the second food loading section is located outside of said cavity, then the other of the first food loading section and the second food loading section is located within said cavity. A first cook setting of the oven when the first food loading section is within the cavity and a second cook setting of the oven when the second food loading section is within the cavity are independently controllable. The first food loading section and the second food loading section may be separated by a divider, which prevents heat from escaping from the cavity through the opening.
Abstract:
A convection oven having one or more intermediate air plenums is disclosed. An intermediate air plenum placed within an oven cavity defines the bottom of an upper cooking chamber and the top of a lower cooking chamber. Each intermediate air plenum comprises a left side air inlet for receiving heated air from a left side air channel located on a left side cavity wall of the oven cavity, a right side air inlet for receiving heated air from a right side air channel located on a right side cavity wall of the oven cavity, a top plenum surface including a plurality of top air outlets configured to direct a portion of the heated air upwards, and a bottom plenum surface including a plurality of bottom air outlets configured to direct a portion of the heated air downwards. The top and bottom plenum surfaces are preferably shaped to optimize even distribution of heated air flow into the oven cavity.
Abstract:
A cooking oven is disclosed. The cooking oven comprises a housing having an oven cavity and an oven door for access to the oven cavity, at least one air blower for generating heated air, one or more air channels for directing the heated air from the air blower toward the oven cavity, and one or more removable air plenums, wherein each removable air plenum is connected to one of the one or more air channels, comprises an air intake edge for receiving the heated air from the air channel, defines the top or the bottom of a cooking chamber within the oven cavity, and comprises a plurality of air vents for directing the heated air into the cooking chamber. The cooking oven may further comprise a control panel for separately and independently controlling each of the cooking chambers defined by the removable air plenums.

Abstract:
A conveyor oven is disclosed. The conveyor oven includes a housing, a conveyor belt, a first and second doors, and a heat source. The housing includes a cavity and a first and second openings. The conveyor belt is configured to receive and transport food items in and out of the cavity through the first and second openings. The conveyor belt includes a loading section and an unloading section for food. The first and second doors cover first and second openings, respectively, in order to prevent heat within the cavity from escaping through the first and second openings during operation. Configured to provide different cooking times and thermal profiles to various types of food items, the heat source provides heat to the cavity for heating up any food item placed on a portion of the conveyor belt located within the cavity.
