A microwave oven having a cabinet, a door, a programming interface, a magnetron tube that capable of being dynamically controlled, a controller configured to control the magnetron tube, and a microwave generating system is described. A method of dynamically controlling the magnetron tube in the microwave oven by utilizing a magnetron power supply is also described. By monitoring a current to the magnetron power supply, determining the current to the magnetron power supply at which the magnetron tube conducts, calculating a time base, and adjusting the time base as the power level required is increased, the control produces consistent power when the magnetron tube is cycled at less than a 100% power level and to compensate for a slow start of the magnetron tube during a short cook cycle.

Dynamic control system for a magnetron tube in a microwave oven

A combination cooking appliance controls a radiant heating element provided in an oven cavity, both a blower and a convection heating element provided in an air plenum, and microwave energy sources to provide for numerous potential operating modes. The present invention is particularly concerned with the manner in which the various cooking components are configured and flexibly controlled to provide for short cook cycles in a variety of operational modes.

Cooking appliance including combination heating system

A cooking appliance includes an outer cabinet within which is provided an oven cavity which can be selectively accessed by movement of a door mounted through a door linkage system which enables the door to be shifted between opened and closed positions through either sliding or tilting movements. In particular, the door can be automatically or manually shifted between open and closed positions, through either the sliding or tilting motions. In accordance with another aspect of the invention, the door can be automatically opened at the end of a process or cooking cycle, or manually opened.

Sliding and tilting door assembly

A microwave oven cabinet is ergonomic designed to provide for both stacking and jigsaw-type back-to-back interlining of multiple units of the microwave ovens. In particular, the cabinet configuration advantageously establishes a reduced footprint, ergonomically designed microwave oven which can be effectively employed in various fields, including fast food chains wherein multiple such ovens may need to be functionally positioned in a limited area, while still being easily accessible.

Modular commercial microwave oven

A microwave cooking appliance includes first and second side mounted microwave systems, each including an associated antenna. Drive structure is provided to establish an oscillating operation for each of the antennae, wherein the angles through which the antennae rotate are configured to assure that the cooking appliance operates in favorable mode patterns. In accordance with the invention, the antenna preferably only oscillates through less than or equal to 180&#xb0; and, most preferably, approximately 150&#xb0;.
