性が極めて困難であった。Conventional Structure and Problems Conventionally, this type of microwave oven has had a high voltage transformer mounted directly on the bottom plate. 'The coil of the transformer reaches a high temperature of around 135 degrees Celsius, which has an adverse effect on the printed circuit board and other parts. Furthermore, because of the magnetic shielding of the high-voltage transformer, the printed circuit board was placed in an iron box, making serviceability extremely difficult.

By attaching a printed circuit board, magnetic shielding can be achieved and the temperature can be maintained at a low temperature.

する。FIG. 2 shows the configuration of a cooling fan 3 and a high-voltage transformer 4 incorporated into a composite cooker integrated with a gas oven. There is a transformer fixing base 5 under the high voltage transformer 4, and a printed circuit board 6 is placed in the transformer fixing base 5. By rotating the cooling fan 30 times, the cooling air intensively cools the magnetron and the high-voltage transformer 4, but some of the air is collected by the anti-fog guide 8 which supplies air to prevent the oven glass from fogging. It penetrates the punch hole 1Q in the wall of the heating chamber 9 and enters the heating chamber 9 to prevent the oven door glass 11 from fogging.

品を冷却した風Ｗ２は加熱室９の底の方へ流れていく。The primary air of the burner 12 is taken in by the excess amount of air from the cooling fan 30. The cooling air opening W1 of the cooling fan 3 reaches the printed circuit board 6 through the gap between the high voltage transformer fixing base 5 and the side plate. Since hot air does not fall near the printed circuit board 6, it can be kept low. The wind W2 that has cooled the parts such as the printed circuit board flows toward the bottom of the heating chamber 9.

き２３と２４によりリード線と連絡する。3 to 7, insulating plates 14 such as fibers are hooked onto the claws 13 at the four corners of the upper plate 5a of the high-voltage transformer fixing base 5, and the printed circuit board 6 is placed under the claws 15 of the high-voltage transformer fixing base 5. The printed circuit board 6 can be placed on the hook 16 of the printed circuit board 6. If it is fixed to the main body with the mounting piece 17 of the printed circuit board 6, it will never come off. Hole 19 for screwing into the bottom plate 18 of the main body
The high-voltage transformer fixing base 6 will not move if the holes 21 are screwed to the front plate 20 and the mounting holes 22 are fixed to the oven door mounting bracket (not shown). It communicates with the lead wire by means of cutouts 23 and 24 for the passage of the lead wire.
以上のように本実施例によれば次の効果を得ることがで
きる。As described above, according to this embodiment, the following effects can be obtained.
（１）高１±１−ランヌ４や低８ニドランス又は各種リ

ってきた。(1) When replacing high 1 ± 1-Lanne 4, low 8 Nid Lance or various relays, chips are removed from the printed circuit board 6.
By installing this insulating plate 14, the problem of falling upward is eliminated. The U-shaped insulating plate 14 prevents cutting dust from accumulating under the U-shape and falling onto the printed circuit board 6. Since the insulating plate 14 is perfectly rectangular, you can simply shear the material. It has become possible to supply the insulating plate 14 at a low cost.
