It penetrates through.
この場合下面の電熱ヒータ８がアンテナとなり、軸受１
０とで同軸伝送線路を形成し、高周波が漏洩する。In this case, the electric heater 8 on the lower surface serves as an antenna, and the bearing 1
0 to form a coaxial transmission line, and high frequencies leak.
この漏洩量は下面の電熱ヒータ８の両辺と、その各辺に
近接する加熱室壁面ｌによって左右され、４分の１波長
の奇数倍で少なく、偶数倍で大きくなる。The amount of leakage depends on both sides of the electric heater 8 on the lower surface and the heating chamber wall surface l adjacent to each side, and is small at odd multiples of a quarter wavelength and large at even multiples.

量に差し支えのない程度にｌの値を２０〜４０鴨の間に
ある寸法を選ぶ必要がある。A quarter at the commonly used 2 450 MHz
Since the wavelength (λ/4) is approximately 30 rran, the optimum distance l from the side wall is about 30 rran, and in practice, the value of l should be between 20 and 40 rran to the extent that there is no problem with the amount of high frequency leakage. You need to choose the dimensions.
又下面の電熱ヒータ８を垂直に立てる方法も考えられる
が、加熱室１の高さには限度があり、水平位置にしたと
きの奥行寸法が短かく、加熱効率が悪くなる欠点がある
。A method of standing the electric heater 8 on the lower surface vertically may also be considered, but there is a limit to the height of the heating chamber 1, and the depth dimension when placed in a horizontal position is short, resulting in poor heating efficiency.
これに対して本実施例の如く傾斜位置にし、壁面との距
離ｌを小さくし、はとんど高周波加熱に邪魔にならない
