産業上の利用分野
本発明は電熱ヒーターと高周波電波を利用した従来複合
加熱調理器のグリルヒーターに面ヒーターを用いている
物は第4図に示すようにオーブン庫の土壁自体を面ヒー
タ−1で構成していた。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention utilizes electric heaters and high-frequency radio waves. Conventional composite heating cookers that use surface heaters as grill heaters can be used in ovens as shown in Figure 4. The earthen wall itself was made up of surface heaters.
面ヒーターは第3図に示すように金属板2の表面をホー

更にホーロー処理3Cをほどこして絶縁する構成になっ
ている。As shown in Fig. 3, the surface heater has a heater element 4 placed on the surface of a metal plate 2 insulated with enamel 3a and 3b.
The structure is further insulated by applying enamel treatment 3C.
発明が解決しようとする問題点
ところが、このような構造の欠点はオーブン庫土壁から
オーブン庫を構成する他の壁面への熱放散が激しく、又
ヒーター素子がオーブン庫外へ出ている為、オーブン庫
内への熱放射と同じ位の熱放射をオープン庫外さも出し
てしまい、従って熱効率が非常に悪いという事である。Problems to be Solved by the Invention However, the disadvantage of this structure is that heat dissipates rapidly from the oven wall to the other walls that make up the oven, and the heater element protrudes outside the oven. The same amount of heat radiation is emitted from the open oven as the heat radiated into the oven, resulting in extremely poor thermal efficiency.
又面ヒーター自体がスポット溶接等でオーブン庫の一壁
面を構成している為、ヒーターの断線や端子の破損等の
不良が発生した場合、ヒーターのみを交換する事が出来
ない為調理器そのものも使用不能になってしまうという
問題もあった。In addition, since the surface heater itself forms one wall of the oven cabinet by spot welding, etc., if a defect such as a disconnection of the heater or a damaged terminal occurs, it is not possible to replace only the heater and the cooker itself. There was also the problem that it became unusable.
そこで、このような問題の解決策としてオープン庫土壁

為、ヒーター素子間で高周波電界によるスパークを生じ
て、ヒーター素子を損傷してしまったり又、ヒーターへ
通電の為のリードセンからオーブン庫内へ電波が漏出す
るのを防止する為の特別なシール装置が必要になる等の
数多くの問題点があった。Therefore, as a solution to this problem, it may be possible to construct the open oven wall with ordinary metal plates and install a surface heater inside the oven, but in this case, the surface heater itself becomes a load of high-frequency radio waves. In addition to causing considerable radio wave loss, since the heater element is directly exposed to the high-frequency electric field, the high-frequency electric field can generate sparks between the heater elements, damaging the heater element. There were many problems, such as the need for a special sealing device to prevent radio waves from leaking into the oven.
本発明はこのような従来の問題点を解消するものであり

ーク、電波ロス等の問題のない品質、信頼性の優れた複
合加熱調理器を提供するものである。The present invention solves these conventional problems, and provides a composite heating cooker with a simple configuration, good thermal efficiency, and excellent quality and reliability without problems such as sparks caused by high-frequency radio waves and radio wave loss. This is what we provide.

設ける構成である。Means for Solving the Problems The present invention has a heating chamber (oven chamber), a high frequency oscillator, and a planar electric heater device provided in the heating chamber in the main body, and the planar heater device has a heating device. A flange portion is provided to maintain a distance between the chamber wall surface and the heater element, and slits are provided at approximately equal intervals at the tip of the flange portion.

ン庫壁への伝導熱による熱放散を防止する。By providing a flange on the working surface heater device to maintain a distance between it and the oven wall, and providing a slit in the contact area of the flange with the oven wall, wasteful heat dissipation from the surface heater can be avoided. can be kept to a minimum, thus greatly improving thermal efficiency. In other words, by providing a space between the sheet heater device and the oven chamber wall, an air layer between the two forms a heat insulating layer, which prevents heat dissipation from the heater to the outside of the oven chamber. By providing a slit in the contact area between the flange and the oven chamber wall, the contact area between the flange and the oven chamber wall is made as small as possible, thereby preventing heat dissipation due to conduction heat from the flange section to the oven chamber wall.

る。In addition, the slit provided in the flange can prevent high-frequency radio waves from entering the back side of the sheet heater device, that is, between the sheet heater and the open storage wall, thereby preventing the sheet heater from being subjected to the radio wave load. Since it is possible to prevent radio waves from being consumed by radio waves, the efficiency of radio waves can also be improved.
更に面状ヒーターへ電力供給の為のリードからオープン
庫外への電波漏洩も防止する事が出来る。Furthermore, it is possible to prevent leakage of radio waves from the lead for supplying power to the sheet heater to the outside of the open refrigerator.

波作用により電波の外周方向の成分の伝播を阻止する。As shown in FIGS. 1(a) and (b), the surface heater device is provided with a flange portion 5.6, 7°8 which is formed by bending the four sides of a rectangular flat plate at right angles to the flat plate surface. Further, the tips of each flange portion are bent parallel to the flat plate surface to form parallel flange portions 9°, 10, 11, and 12, and a plurality of equally spaced slits 13 are provided in these parallel flange portions 9 to 12. As shown in FIG. 2, the zero-side heater device is attached to the upper part of the oven chamber so that the parallel flange portion and the oven soil wall are in contact with each other. Since the length of the parallel flange is approximately 1/4 of the wavelength used, the tip of the flange becomes the open end of the radio wave, and the root part separated by λ/4 becomes the seat part. As is well known, the slit 13 prevents the propagation of the components of the radio wave in the outer circumferential direction due to the slow wave effect.

る事が出来る。It is better to make the width of the slit 13 as large as possible in order to reduce heat conduction, but in terms of radio waves, it is necessary to make the width λ/4 or less. Although this structure does not have a perfect choke structure, when the entire surface heater device is attached to the upper part of the oven interior, the surface heater device and the upper oven wall 14
It has sufficient performance to suppress the amount of radio waves that enter between the wall and the wall to a few 1 to several tens of WW, and if it is kept to that level, the surface heater is as effective for radio waves as other walls that make up an open storage. It only acts as a load, and is not a problem in terms of radio wave loss. Regarding radio wave leakage to the outside of the open oven, in order to keep the power density in the space consisting of the oven wall and the surface heater device low, a flange is installed at the opening 16 through which the lead wire 15 of the surface heater passes. If the portion 17 is provided to make it as difficult as possible for the radio waves to get onto the lead wire, it is possible to sufficiently prevent the problem from becoming a problem.

る。The method of installing the surface heater device in an open oven is to sandwich one end between the insulator 19 attached to the upper part of the rear wall of the oven and the open oven wall, and insert the other end into the screw hole 20.
and 20' are fixed to the upper wall of the oven with screws.

上きわめて優れた効果を有する。Effects of the Invention By installing the surface heater in the oven so that the slit surface provided on the parallel flange of the surface heater contacts the oven soil wall, the contact area between the surface heater and the open oven wall is minimized, and the surface At the same time, it reduces heat dissipation from the heater to the open storage wall and improves thermal efficiency.
The slits provided in the parallel flange prevent radio waves from entering between the surface heater and the open storage wall, thereby preventing the surface heater itself from becoming a load on radio waves, improving the efficiency of radio waves. It has an extremely excellent practical effect.
