Abstract: Food stuffs are cooked at precise temperatures, which are optionally below 100° C., in a vessel that is evacuated to exclude air, in which low pressure steam replaces the air. When a sufficient quantity of air is excluded and replaced with water vapor, the temperature of vapor is accurately measured inside the vessel below the lid to control the temperatures within about 1° C. Air is preferably excluded via a controlled heated process for a relatively short period of time at high temperature to generate steam, the temperature is lowered to condense water vapor upon which the lid will sealingly engage the rim of the vessel, forming a partial vacuum in the cooking vessel.

Abstract: An appliance includes an outer wrapper and an inner liner placed within the outer wrapper and spaced apart from the outer wrapper to define an insulating space. A trim breaker extends between the inner liner and the outer wrapper to define a structural cabinet. The trim breaker defines a front face of the cabinet. The trim breaker defines a gas conduit disposed within a wall of the structural cabinet proximate the insulating space. The gas conduit is adapted to define selective communication between the insulating space and an exterior of the structural cabinet. An insulating material is disposed within the insulating space, wherein the gas conduit is substantially free of the insulating material.

Abstract: An RF generation system is provided for an electromagnetic cooking device having a cavity. The system includes: a signal generator for generating an input RF signal; an RF feed configured to introduce electromagnetic radiation into the cavity and to receive reflected electromagnetic radiation from the cavity; and a high-power amplifier coupled between the signal generator and the RF feed. The high-power amplifier including an amplifying stage configured to output a signal that is amplified in power, and a circulator for directing the amplified output signal to the RF feed and for redirecting any reflected radiation received from the RF feed to a dummy load. The system further includes a hardware protection component for detecting backward power in the reflected radiation and for reducing power supplied to the amplifying stage if the backward power exceeds a power threshold within a time scale that prevents damage to the circulator.
