Title: Microwave oven
Inventor: INAMI ICHIRO
IPC: F24C7/02
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To prevent the intrusion of noise from the outside air to a wiring part inside an equipment so as to lower the noise to be leaked outside through the wiring by arranging wiring of a low voltage side circuit or a high voltage side circuit in a groove-like wiring passage so that the wiring is surrounded by a metal body. SOLUTION: A power source cord 1 is connected to a noise filter 5 through a low voltage circuit side wiring 3, and furthermore, connected to a high voltage transformer 6 through a wiring part 3a. In the case where the wiring part 3a is arranged in a space inside of an electrifying chamber 2, the wiring part 3a is easy to be intruded with the noise from an equipment such as a magnetron 12, and in the case of a large noise, noise is leaked to the power source cord 1, though a noise filter 5 is provided. In the case where a bottom surface 10 is formed with a groove-like wiring passage 7 so as to house the wiring part 3a, the wiring part 3a is surrounded by a metal body, and intrusion of noise to the wiring part 3a can be prevented so as to lower the noise to be leaked outside.
