熱室の温度を１屏さゼる方法が用いられている。Conventional technology Conventionally, as a general method to reduce the temperature inside a heating chamber, an insulated nichrome wire or the like is placed inside or outside the heating chamber, and is heated using a commercial power supply. A method of lowering the temperature of the room by one screen is used.

In addition, the insulation gradually deteriorated due to the heat from the heater, resulting in poor durability and danger. Furthermore, there was a temperature difference between one part of the heater and the other part, resulting in uneven heating of the food.

Furthermore, since the entire wall is exposed to light and heat, uneven heating occurs, and since the secondary winding to which the wall is connected is for low voltage, there is no risk of electric shock.

である。FIG. 1 is a sectional view of a heating cooker according to an embodiment of the present invention. In FIG. 1, 1 is installed inside the cooking device main body 2 (
This heating chamber 1 is a heating chamber where food is heated by heating.
The wall 3 forming the
It is made of metal that has a certain electrical resistance. Further, a transformer 4 that converts the voltage of the commercial power supply to a lower voltage is also arranged within the cooking device main body 2. A primary winding 6 wound on the C side of the core 5 of the transformer 4 is insulated from the core 5 of the transformer 4 by a bow 7 made of an insulating material. A secondary winding 8 made of a metal with almost no electrical resistance, such as copper, is wound on the other side of A 5, and both ends of the secondary winding 8 are connected to the heating wall via screws 9, etc. It is firmly connected to the body 3. 10 is a heat insulating material disposed around the wall body 3.

こと（よない。In the above configuration, when a 100V commercial power supply is connected to the 11th @ wire 6, a current of about 1 (1)/mbair flows through the primary winding 6, and a voltage of about several volts flows through the secondary winding 8. Here, since the electrical resistance of the wall 3 of the heating chamber 1 is approximately several milliohms, a current of several amperes flows through the wall 3, resulting in a voltage of 1K.
Heat of approximately W is generated from the entire wall body 3, and the inside of the heating chamber 1 is heated to a temperature of -L with high efficiency and without temperature unevenness. Note that the secondary winding 8 to which the wall 3 is connected is insulated from the primary winding 6 to which the bending power source is connected and has a low voltage. It is also possible to receive an electric shock.
発明の効果 以上のように、本発明によれば以上の効果がある。Effect of the invention As described above, the present invention has the above effects.
■ 加熱室の壁体自体に電流を流しで加熱室を加熱づる
ので加熱Ｔ内の温度上がが甲く、熱効率がよい。■ Since the heating chamber is heated by passing an electric current through the heating chamber wall itself, the temperature inside the heating T is high and thermal efficiency is good.
■ 加熱室の壁体に接続された２次巻線と１次巻線とは
絶縁されていて、かつ加熱室の壁体の電圧は２次巻線と
同じく低いため、人が加熱室の壁体に触れても感電の心
配はない。したがっＣ従来のような絶縁物の劣化などに
よる感電などはない。■ The secondary winding and primary winding connected to the wall of the heating chamber are insulated, and the voltage on the wall of the heating chamber is as low as the secondary winding, so people cannot touch the wall of the heating chamber. There is no risk of electric shock if you touch your body. Therefore, there is no electric shock caused by deterioration of the insulation as in the conventional case.
■ 加熱室の壁体全体で加熱ブるため、加熱室内の温度
むらがなく調理物の加熱むらはほとんど生じない。■ Since the entire wall of the heating chamber is heated, there is no temperature unevenness within the heating chamber, and there is almost no uneven heating of food.
