10は高周波減衰室9の入口、11はヒータ4
の両端部を保持し、これとともに上下方向へ移動
する金属性の移動板で、遮へい板7との間に所定
の間隙Sを形成している。12はこの移動板の両
側縁部に一連に形成した折曲部で、加熱室2の側
面と所定長さW、例えば高周波の1/4波長相当
以上にわたつて近接対面している。 10 is the entrance of the high frequency attenuation chamber 9, 11 is the heater 4
It is a metal moving plate that holds both ends of the shield plate 7 and moves in the vertical direction together with the shield plate 7, and forms a predetermined gap S between it and the shield plate 7. Reference numeral 12 denotes a series of bent portions formed on both side edges of the movable plate, which closely face the side surface of the heating chamber 2 over a predetermined length W, for example, equivalent to 1/4 wavelength of high frequency waves or more.
13は移動板11の前面に当接したローラー、
14はこのローラーを回転自在に支持した金属性
取付板で、加熱箱1の背面に2つの遮へい板7の
全周を囲むように取り付けられている。15はこ
の取付板の遮へい板7との対向面にその全長にわ
たつて取り付けた電波吸収体、16は移動板11
の背面に当接したローラー、17はローラーホル
ダーである。 13 is a roller that is in contact with the front surface of the moving plate 11;
Reference numeral 14 denotes a metal mounting plate that rotatably supports this roller, and is attached to the back of the heating box 1 so as to surround the entire periphery of the two shielding plates 7. 15 is a radio wave absorber attached to the surface of the mounting plate facing the shielding plate 7 along its entire length; 16 is a moving plate 11;
The roller 17 in contact with the back surface of the roller is a roller holder.
以上の構成であるから、今高周波加熱を行なう
と透孔3から高周波が外部へもれようとするが、
この考案では高周波減衰室9を備えているのでか
かる高周波をほとんど消滅させられる。そしても
しここでも消滅しない高周波が間隙Sを通つて外
部へ出たとしても次に電波吸収体15によつて吸
収され、消滅させられるものである。 With the above configuration, if high-frequency heating is performed now, high-frequency waves will leak to the outside from the through holes 3, but
In this invention, since the high frequency attenuation chamber 9 is provided, such high frequencies can be almost completely eliminated. Even if a high frequency wave that is not extinguished here goes out through the gap S, it will be absorbed by the radio wave absorber 15 and extinguished.
一方移動板11を操作すればローラー13・1
6により安定して移動させられるので、ヒータ4
の高さを任意に選べる。 On the other hand, if the moving plate 11 is operated, the rollers 13.1
Heater 4 can be moved stably by heater 6.
The height can be selected arbitrarily.
以上のようにこの考案によればヒータを平行移
動させられるので、例えヒータの発熱量が一定で
もその高さを変えることにより被加熱物に対する
火力を強火から弱火まで幅広くコントロールでき
るものであり、広範囲の被加熱物に対応でき、か
つ熱効率を向上させることができる。さらに取付
板を利用し電波吸収体とローラーを取付けている
ので高周波の漏洩を十分に阻止できるとともに別
個に取付手段を必要とせずその構造も簡単になる
という効果がある。 As described above, according to this invention, since the heater can be moved in parallel, even if the heat generation amount of the heater is constant, by changing the height of the heater, the fire power applied to the object to be heated can be controlled over a wide range from high heat to low heat. It is possible to cope with objects to be heated, and improve thermal efficiency. Furthermore, since the radio wave absorber and the roller are mounted using a mounting plate, leakage of high frequency waves can be sufficiently prevented, and a separate mounting means is not required, making the structure simple.
