本発明は、商用電源を用いる加熱手段を二つ以上併設し
た複合調理器に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a composite cooker equipped with two or more heating means using commercial power.
従来、この種の複合調理器においては、多様な調理法に
要求される熱量、温度、および加熱方法のそれぞれの違

熱手段との組み合わせによる複合調理器が開発されてい
る。そして、上記したようなそれぞれの手段を一体的に
組み合わせた複合調理器は、−台で同時に、且つ複数の
調理が可能になるといった点で便利なものである。Conventionally, in this type of composite cooker, in order to respond to the differences in heat amount, temperature, and heating method required for various cooking methods, control of nichrome wire heaters, halogen heaters, sheathed heaters, etc. Although a simple and simple combination of electric resistance heating means has often been used, in recent years, a composite cooker has been developed that combines the above-mentioned electric resistance heating means and electromagnetic induction heating means. A composite cooking device that integrally combines the above-mentioned respective means is convenient in that it is possible to simultaneously perform a plurality of cooking operations on one unit.
ところで、上記したような従来の複合調理器において、
電気抵抗加熱手段同志を組み合わせたものは、その制御
方法が電子回路を使用するような複雑なものを必要とせ
ず、その使用時の高温対策はほとんど為されずに済んで
いる。By the way, in the conventional composite cooker as mentioned above,
A combination of electric resistance heating means does not require a complicated control method such as the use of electronic circuits, and there is almost no need to take measures against high temperatures during use.
しかしながら、電磁誘導加熱手段においては、商用電源
を整流したり、高周波を発生させ、その周波数を制御す

電磁誘導加熱手段とを組み合わせた従来の場合において

熱手段からの熱が、輻射、および伝導等によって、制御
手段を具備する電磁誘導加熱部に伝わるために、上記制
御手段が高温に曝されるという不都合があった。それに
より、制御手段を構成するトランジスタ、ダイオード等
の、熱に弱い電子部品が、熱劣化したり、作動不良に至
るといった問題点があった。However, the electromagnetic induction heating means requires a control means for rectifying the commercial power supply, generating a high frequency, and controlling the frequency. Even in the conventional case where electricity is a combination of anti-heating means and electromagnetic induction heating means, the heat from the electric resistance heating means, whose temperature reaches about 750°C, is controlled by radiation, conduction, etc. There is a disadvantage in that the control means is exposed to high temperatures because the heat is transmitted to the electromagnetic induction heating section provided with the means. As a result, heat-sensitive electronic components such as transistors and diodes constituting the control means suffer from thermal deterioration or malfunction.
従って、本発明の目的とするところは、電気抵抗加熱手
段と電＆１）銹導加熱手段とを一体的に内蔵した場合で
も、電気抵抗加熱手段から電磁誘導加熱手段へ高温の熱
が多量に移動しない複合調理器を提供することにある。Therefore, the object of the present invention is to prevent a large amount of high-temperature heat from being transferred from the electric resistance heating means to the electromagnetic induction heating means even when the electric resistance heating means and the electric conduction heating means are integrated. Our goal is to provide a multi-purpose cooker that does not.

記両川熱部が、断熱部材により熱的に仕切られたことを
特徴とする複合調理器である。The gist of the means adopted by the present invention to achieve the above object is that an electromagnetic induction heating unit is provided with an electromagnetic induction heating means and a control means for controlling the electromagnetic induction heating means within the main body case. , a composite cooking appliance comprising an electric resistance heating section equipped with electric resistance heating means, characterized in that the Ryogawa heating section is thermally partitioned off by a heat insulating member.
本発明によれば、調理に際して電気抵抗加熱手段が入電
されると、電気抵抗加熱部は、その温度が上昇して高温
の雰囲気になる。続いて、その高温の熱は、比較的低温
の電磁誘導加熱部に向けて移動しようとする。According to the present invention, when power is applied to the electric resistance heating means during cooking, the temperature of the electric resistance heating section rises to create a high-temperature atmosphere. Subsequently, the high temperature heat attempts to move towards the relatively low temperature electromagnetic induction heating section.
しかしながら、電気抵抗加熱部と電磁誘導加熱部との間
に配設された断熱部材により、上記それぞれの加熱部が
仕切られているので、輻射、および伝導等により移動し
ようとするりへは、熱伝導率が小さな断熱部材により、
その移動が極力抑えられる。However, since each heating section is separated by a heat insulating member placed between the electrical resistance heating section and the electromagnetic induction heating section, the heat is not transferred by radiation or conduction. Due to the insulation material with low conductivity,
Its movement is suppressed as much as possible.
そのために、電磁誘導加熱部への熱は、その移動量が小
さくなることから、電磁誘導加熱部に具備される制御手
段が高温に曝されることがない。Therefore, since the amount of heat transferred to the electromagnetic induction heating section is small, the control means provided in the electromagnetic induction heating section is not exposed to high temperatures.
