A hand protecting cavity ventilation system for an oven is provided. The system includes an air duct, positioned at a top of a cavity of the oven, the air duct having a duct outlet aimed toward a door to the cavity to provide an airflow along an inner surface of the door. The air duct extends downward from the ceiling of the cavity in front of and below a heating element disposed below the ceiling of the cavity. The air duct forms a vertically displaced hand protection portion to act as a barrier in front of the heating element, thereby guarding the heating element when the door of the oven is opened.

Disclosed are systems and methods that optimize electrical component compartment cooling in a cooking device, such as a combi-steamer. The systems and methods according to the present disclosure provide supplemental air movement devices, such as fans, in the electrical component compartment and, optionally, in the mechanical compartment. These supplemental air movement devices allow reducing the energy consumption of cooking ovens such as combi-steamers by reducing the effort required by a main cooling fan to cool the electrical compartment. Reducing the effort required by the main cooling fan to cool the electrical compartment also reduces or avoids the cooling effect that over-use of the main cooling fan has on the cooking chamber. Also, temperature fluctuations in the electrical compartment are reduced which can also prolong the effective life of the electrical components, again reducing operating and repair costs for the cooking device.

A cooking apparatus including a main body forming a cooking room therein and including a front plate with an opening to the cooking room; a case positioned to one side of the opening and formed to accommodate a circuit board therein; a door opening and closing the opening and covering a front portion of the case, wherein a portion of a rear surface of the door is depressed inward to accommodate the case. The cooking apparatus includes a circulating air outlet formed at a top of the main body, and configured to filter and discharge air received from below the main body; and a suction grill attachable to and detachable from an upper portion of the case and accommodated in one side of the door, wherein a cooling air inlet, which allows cooling air to enter through the suction grill, is positioned in front of the circulating air outlet.

A microwave cooking appliance having a connector system connecting the appliance to an external vent configuration. The connector system may include an adaptor. The connector system may include a mounting bracket to mount the microwave cooking appliance. The adaptor and/or mounting bracket may include one or more magnets to magnetically connect the adaptor with the mounting bracket. The connector system may include a sealing system.

The present invention is a heater or heating device that uses microwave energy to generate heat quickly. The heater generates heat quickly by forcing air over microwave-heated oil or non-freeze liquid. As a non-limiting embodiment, the heater preferably includes most or all of the following components: an outer casing or housing, at least one air intake vent, a magnetron, a microwave emitter, a wave scatterer, at least one fluid holder, fluid, a capacitor, a transformer, a microwave containment casing, and a perforated microwave guard. As another non-limiting embodiment, the heater preferably includes most or all of following components: an outer casing or housing, a cooling fan, a magnetron, a microwave emitter, a wave scatterer, at least one non-freeze liquid holder, non-freeze liquid, a capacitor, a transformer, a microwave containment casing, a glass tube, a metal tube, a fan coil, a pump, a reservoir and expansion tank, and a fill plug.

Control electronics may control power amplifier electronics associated with application of RF energy generated using solid state electronic components. The power amplifier electronics may be configured to control application of RF energy in an oven according to a cooking recipe at least in part based on a learning procedure that generates a power cycling between high and low powers when the learning procedure is executed. The control electronics may include processing circuitry configured to employ a thermal stress mitigation technique to control thermal stresses on the power amplifier electronics associated with the power cycling.

A ventilation system for an oven is provided. The system includes a rear duct assembly. The rear duct assembly includes vertical walls defining a vertical air flow path along a rear of the oven, and a separator plate dividing the vertical air flow path into a first air flow configured to receive air from oven electronics and a second air flow configured to receive air from an oven cavity. The separator plate extends vertically downward between the vertical walls from the top of the vertical air flow path a portion of the height of the oven until a mixing zone at the rear of the oven into which the first and second air flows combine into a combined air flow.

A ventilation system for an oven is provided. A side duct assembly includes a substantially vertical exit duct portion adjacent to an oven cavity wrapper defining an oven cavity of the oven, the substantially vertical exit duct portion having an air intake configured to receive a cavity air flow from an air intake along a side of a cavity wrapper. The side duct assembly further includes an angled duct portion defining an air passage angled upwards and towards a rear of the oven, the angled duct portion having an input end configured to receive the cavity air flow from the top of the substantially vertical exit duct portion and an output end configured to provide the cavity air flow into a mixing zone at the rear of the oven for mixing the cavity air flow with an electronics air flow from oven electronics into a combined air flow.

A heating cooking apparatus (1) includes a heating cooking chamber (10), a housing (14), an opening/closing portion (30a), and a microwave supply unit (23). The opening/closing portion (30a) includes a flowing portion (31), a cam (32), a drive unit (33), a lid portion (34), and a biasing portion (35). The flowing portion (31) includes an opening (310B) that faces a through hole (10A1). The flowing portion (31) forms, between the flowing portion and the wall portion (10A), an inner space (IR) through which air flows. The cam (32) fits into the opening (310B). The drive unit (33) rotates the cam (32). The lid portion (34) opens or closes the through hole (10A1) in response to the rotation of the cam (32). The biasing portion (35) biases the lid portion (34) in a direction away from the through hole (10A1). The cam (32) presses the lid portion (34) against biasing force of the biasing portion (35) to cause the lid portion (34) to close the through hole (10A1).

Disclosed herein is a cooking apparatus. The cooking apparatus includes a housing, a cooking chamber formed in the housing, a heater arranged on one side of the cooking chamber, a door coupled to the housing to open and close the cooking chamber, the door including a door body provided to form an exterior of the door, a handle recessed from an outer surface of the door body, and a cooling plate positioned adjacent to an inner surface of the door body corresponding to the handle so as to dissipate heat that is generated by the heater and transferred to the handle.
