ある為所定の温度に達する時間が長く必要とした。Problems to be Solved by the Invention However, in the former case, the temperature in the heating chamber reaches the specified temperature quickly, but the surface of the object to be heated may be burnt due to the infrared rays of the sheathed heater, and the shape of the sheathed heater There was uneven baking. In the latter case, since the walls of the heating chamber are heated, there is little infrared radiation and less uneven heating. However, since the heat from the heater needs to be transmitted once to the heating chamber wall, it takes a long time to reach a predetermined temperature.
そこで本発明は、上記欠点に鑑み、加熱室内を所定の温
度に上げる時間を短くするとともに、加熱室内の温度む
らをなくし被加熱物の焼むらを抑えた加熱調理器を提供
しようとするものである。In view of the above-mentioned drawbacks, the present invention aims to provide a cooking device that shortens the time it takes to raise the heating chamber to a predetermined temperature, eliminates temperature unevenness in the heating chamber, and suppresses uneven cooking of the object to be heated. be.
問題点を解決するための手段
そこで、本発明の加熱調理器は加熱室壁を、強磁性体で
構成し、商用周波数をインバーター回路にて高周波に変

するものである。Means for Solving the Problems Therefore, in the heating cooker of the present invention, the heating chamber wall is made of a ferromagnetic material, and the electric current obtained by converting the commercial frequency to high frequency using an inverter circuit is placed outside the heating chamber wall. This is what supplies the coil to the coil.
作 用
強磁性を有する金属に高周波の交流の磁界を加えると、
その金属は磁界のヒステリシス損によシ発熱する誘導加
熱が生じる。この誘導加熱を、加熱室壁に作用すること
によシ、加熱室内の温度むらをなくし、温度上昇時間を
大巾に短縮できる。Action When a high-frequency alternating current magnetic field is applied to a ferromagnetic metal,
The metal undergoes induction heating that generates heat due to hysteresis loss in the magnetic field. By applying this induction heating to the heating chamber wall, temperature unevenness within the heating chamber can be eliminated and the temperature rise time can be greatly shortened.
