Abstract:
PROBLEM TO BE SOLVED: To make a low-voltage oscillation tube which is usable for microwave ovens and make microwave ovens small and light-weight by installing a klystron which is operated and provides an output with a prescribed energy, when an electric power source is turned on, a cooking chamber, and a control means. SOLUTION: A control part 500 installed in the front right side of a microwave oven 300 supplies prescribed electric power to a klystron 400 and a cooling fan 380 by operation by a user. The keystron 400 is operated by electric power supply from an electric power source 310 and generates electromagnetic waves through an antenna. After the electromagnetic waves have been guided to a cooking chamber through a waveguide 300, the electromagnetic waves are diffused by a stirrer and radiated to the food in the cooking chamber to carry out cooking. In the case a multibeam klystron is used as the klystron 400, no high-voltage transformer is required to be used, the structure and the parts of the microwave oven are simplified, the weight is made light, and the thickness is reduced.
