The rotary plate 5 is installed on the bottom surface of the cooking chamber 2, and the cooking object to be cooked is placed on the upper surface thereof. The rotary plate 5 is rotated by a drive motor (not shown) provided on its bottom surface. In addition, reference numeral 7 denotes a front panel, 8 an air guide, 9 a cooling fan, HVT is a high voltage transformer, HVC is a high voltage capacitor, HVD is a high voltage diode, and MGT is a magnetron. These are installed in the apparatus chamber 3. The high voltage transformer (HVT) boosts the AC / AC of 120 / 230V to a voltage of approximately 2000V, which is converted into a high voltage of approximately 4000V through the high voltage capacitor (HVC) and the high voltage diode (HVD). Magnetrons (MGTs) are driven at this high voltage to generate microwaves of approximately 2450 MHz. The cooling fan 9 blows air to cool the electrical components inside the apparatus chamber 3, in particular, the magnetron (MGT), the high voltage transformer (HVT), and the like, which generate high heat. The air guide 8 is installed near the magnetron (MGT) to guide the heated air in the cooling process of the magnetron (MGT) to the cooking chamber (2). The front panel 7 is installed on the front of the apparatus room 3 to input the operation state of the user and display the operation state of the microwave oven.
