The purpose is to improve the operability of operating switches, etc.
第1図aは従来のこの種の加熱装置の構成を示すもので
ある。FIG. 1a shows the configuration of a conventional heating device of this type.
被加熱物は、ラッチ機構等を内蔵するバンドル1を操作
することにより扉2を開閉し、加熱室3内部に設置され

Operation panels have become complex and require a large amount of space.
スペースの問題は加熱室の大きさに対する操作パネルの
体積比を必然的に増加させた。Space problems have necessitated an increase in the volume ratio of the operating panel to the size of the heating chamber.
このとき、従来より用いられているパネル6の加熱室前
壁8へのとりつけは不適当なものとなった。At this time, the conventional method of attaching the panel 6 to the front wall 8 of the heating chamber became inappropriate.
第2図に示すのは、従来より用いられる方法により操作
パネルをとりつけた場合をしめしているが、操作ツマミ
が加熱室上壁9よりも上方までのびた結果、操作ツマミ
7を操作するとき、ツマミ部分が全体的に変位し、操作
の感触を悪化させ、さらに操作自体不確実となり、きわ
めて品位を低下させてしまった。Fig. 2 shows a case where the operation panel is attached using the conventional method.As a result of the operation knob extending above the heating chamber upper wall 9, when operating the operation knob 7, the knob The entire portion was displaced, which worsened the feel of operation, and furthermore, the operation itself became uncertain, resulting in an extremely poor quality.
生産ラインにおいてこの方式のまま組立調整を行なうと
、その不確実さから組立、調整不良が続発するに至った
のである。If assembly and adjustment were carried out using this method on the production line, the uncertainty caused a series of assembly and adjustment errors.
本考案はかかる状況にて考案されたもので、前述の操作
パネル6の取付けにかかる加熱室前板8の強度をあげ、
操作ツマミの操作を確実にする様にしたものである。The present invention was devised under such circumstances, and it increases the strength of the heating chamber front plate 8 for mounting the aforementioned operation panel 6.
This ensures reliable operation of the control knob.
以下本考案の実施例について添付図面とともに説明する
。Embodiments of the present invention will be described below with reference to the accompanying drawings.

この前板は上下の端面にそれぞれ曲げフランジ10.1
1を設けている。This front plate has bent flanges 10.1 on the upper and lower end faces respectively.
1 is provided.
又操作パネル6はこの加熱室前板8に固定している。Further, the operation panel 6 is fixed to this heating chamber front plate 8.
12は電熱加熱を行なうヒータ、13は高周波の遮蔽を
行なうシールドケースである。Reference numeral 12 is a heater that performs electric heating, and reference numeral 13 is a shield case that shields high frequency waves.
以上の構成にさらに本考案においては、前記導波管4の
端面フランジ14のビス穴15と、前記加熱室前壁8の
上面フランジ10の一部分を固定させる補強板16を設
けた。In addition to the above structure, in the present invention, a reinforcing plate 16 is provided to fix the screw hole 15 of the end flange 14 of the waveguide 4 and a part of the upper flange 10 of the front wall 8 of the heating chamber.
この補強板16は、金属を打ち抜き、曲げ加工して、前
述のフランジ10と、フランジ14間に特別な応力を加
えることなくビス締めができる様にしている。This reinforcing plate 16 is formed by punching and bending metal so that screws can be tightened between the flanges 10 and 14 without applying special stress.
さらに補強板のフランジ10との取付部はキメ穴とし、
又一方フランジ14のビス穴部分に対向する面には長穴
を設け、加熱室前壁8と導波管4の組立上のピッチのバ
ラツキを吸収するとともに、逆に一定ピッチに調整でき
る様にしている。Furthermore, the attachment part of the reinforcing plate to the flange 10 is made with a textured hole,
On the other hand, elongated holes are provided on the surface of the flange 14 facing the screw holes to absorb variations in the pitch when assembling the heating chamber front wall 8 and the waveguide 4, and conversely to make it possible to adjust the pitch to a constant pitch. ing.
以上の構成により、この補強板の両端をそれぞれフラン
ジ10とフランジ14にビスどめを行なった。With the above configuration, both ends of this reinforcing plate were screwed to the flanges 10 and 14, respectively.
この構成により、つぎの様な効果をうろことができた。With this configuration, we were able to achieve the following effects.
すなわち、フランジ10とフランジ14を補強板で外部
よりの応力がくわわっても等しいピッチを維持できる様
にしたため、加熱室前壁8は、加熱室上板9よりも上側
でのソリ変形がなくなり、その結果、操作パネル6は変
位することもなく、操作ツマミの操作は確実となりさら
に操作の感触も非常に良好なものとなった。In other words, since the flanges 10 and 14 are made with reinforcing plates so that they can maintain the same pitch even when external stress is applied, the front wall 8 of the heating chamber is free from warping deformation above the upper plate 9 of the heating chamber. As a result, the operation panel 6 did not displace, the operation knobs could be operated reliably, and the feel of the operation was also very good.
そして本考案によれば波及的に次のような大きな効果を
もたらすことができた。According to the present invention, the following major effects could be brought about in a ripple effect.
第3図はその効果を示す図でaは従来方式のもの、bは
本考案によるものである。FIG. 3 is a diagram showing the effect, in which "a" is the conventional method and "b" is the one according to the present invention.
第3図aによれば、ヒータ13が動作すると、その周囲
よりしだいに温度が上昇し、加熱室上板9はその温度に
より膨張し、導波管4および高周波発生装置5の重力に
より上側にソリを発生する。According to FIG. 3a, when the heater 13 operates, the temperature gradually rises from its surroundings, and the heating chamber upper plate 9 expands due to the temperature and moves upward due to the gravity of the waveguide 4 and the high frequency generator 5. Generates sledding.
このソリの量は数mm以上となりこれにより、加熱室の
形状変化が生じ、高周波に対するインピーダンスが変化
する。The amount of warpage is several mm or more, which causes a change in the shape of the heating chamber and changes the impedance to high frequencies.
このため、電熱加熱直後に高周波加熱を行なうと、この
インピーダンスの変化が高周波発生装置5の動作点を変
化させ結果的にモーデングの発生や出力の低下など不安
定動作となってしまっていた。Therefore, if high-frequency heating is performed immediately after electrothermal heating, this change in impedance changes the operating point of the high-frequency generator 5, resulting in unstable operation such as occurrence of moding and reduction in output.
本考案に係る補強板を使用した場合、前記導波管4の端
面フランジ14(この部分は温度変化により変位のもつ

しているため、高周波発生装置等の加重を加熱室前壁8
にてささえることとなり、この変化をおさえることがで
きる。When the reinforcing plate according to the present invention is used, the end flange 14 of the waveguide 4 (this part is the part where the displacement is large due to temperature change) is the same as the flange 1 of the heating chamber front plate 8.
0 and the front wall of the heating chamber 8 with screws to keep the pitch nearly constant.
This change can be suppressed by supporting it.
そのため、高温時のオーブンインピーダンスの変化が少
なくなり、より高周波発生装置を安定に動作させること
ができるようになった。Therefore, changes in oven impedance at high temperatures are reduced, making it possible to operate the high frequency generator more stably.
さらに、この導波管4の先端フランジ14の変化は第3
図すに示すごとく同時に加熱室前壁の前後のソリとなっ
てあられれるが(高温で加熱室後方にそる。Furthermore, the change in the tip flange 14 of this waveguide 4 is caused by the third change.
As shown in the figure, the front wall of the heating chamber warps at the same time (it warps toward the rear of the heating chamber at high temperatures).

さなものとする。As shown in the figure, when the hook 17 shifts backward, it is pulled toward the rear of the door 2 whose closed position is regulated by the key 18, and as a result, the gap 19 between the heating chamber front wall 8 and the door at high temperatures is reduced. shall be.
このためこの間より逃げる電熱加熱時の熱や高周波加熱
時の高周波の量すなわち洩れ量を非常に少なくすること
ができるのである。Therefore, the amount of heat during electric heating and high frequency during high frequency heating, that is, the amount of leakage, can be extremely reduced.
