Abstract
A microwave oven having a wave distributing device. A motor-operated rotor is installed inside a cooking cavity to distribute high-frequency electromagnetic waves (“microwaves”) generated by the oscillation of a magnetron. The wave distributing device includes a rotation trace limiter which limits a rotation trace of the rotor within a predetermined range. The rotation trace limiter includes stoppers which limit the rotation of the rotor, or a cam mechanism unit which changes a movement of a motor shaft connecting the rotor to the motor. Accordingly, an optimum energy efficiency is achieved, thereby saving energy required during an operation of the microwave oven under a standard load. In addition, the amount of the microwaves reflected back to the magnetron during an operation under a no-load or a light load is reduced. Therefore, life expectancy of the magnetron and the overall operational reliability of the microwave oven are improved.
