としている。Conventionally, this type of rice cooker generally has a configuration as shown in FIG. That is, the rice cooker body 1 has the pot 2 and the protective frame 3 inside. The protective frame 3 is composed of two parts, a protective frame bottom portion 3-a and a protective frame body 3-b, and an upper frame 4 is arranged above the protective frame body 3-b. An induction coil 5 is arranged on the outer surface of the protective frame bottom 3-a so as to face the bottom of the pan 2 and is held by a protective cover 6. A ferrite 7 is attached to the outer surface of the protective cover 6, and the ferrite 7 is configured to enhance inductive coupling and perform magnetic shielding to the outside.

が高くなるという問題があった。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In such a conventional rice cooker, the protective cover 6 is necessary for holding the induction coil 5 and also for maintaining the insulation between the induction coil 5 and the ferrite 7. Since the protective frame bottom portion 3-a and the entire induction coil 5 are provided so as to be covered, the components are unnecessarily large and the cost is increased.
本発明は上記問題を解決するもので誘導コイルを簡単に
保持し、かつ、フェライトを誘導コイルの絶縁も行える
ようにした炊飯器を提供することを目的としている。An object of the present invention is to solve the above problems and to provide a rice cooker that can easily hold an induction coil and can also insulate the induction coil with ferrite.
課題を解決するための手段 本発明は上記目的を達成するために、誘導コイルを複数
のフェライトで、フェライトと同幅または少し大きめの
絶縁体を介して挟持する構成としたものである。Means for Solving the Problems In order to achieve the above object, the present invention has a configuration in which an induction coil is sandwiched by a plurality of ferrites with an insulator having the same width as or slightly larger than the ferrites interposed therebetween.
作用 上記構成において、誘導コイルは小さい絶縁体とフェラ
イトのみで保護枠底部に挟持させられることとなる。Action In the above-mentioned configuration, the induction coil is sandwiched between the small insulator and the ferrite on the bottom of the protective frame.
実施例 以下、本発明の一実施例を第１図および第２図を参照し

る。Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In this embodiment, the same components as those described above are designated by the same reference numerals, and the description thereof will be omitted. The characteristic structure of this embodiment is the mounting structure of the induction coil unit. That is, the induction coil 5 is arranged on the outer surface of the protective frame bottom portion 3-a so as to face the bottom portion of the pot 2 and is made of an insulator 9 made of synthetic resin or the like.
The ferrite 10 is sandwiched between the ferrite 10 and the ferrite 10, and the ferrite 10 is held by the hook portion 11 provided on the bottom portion 3-a of the protective frame.
前記絶縁体９はフェライト10の横幅と同等であれば絶縁
を確保できるので、極力狭くし、またフック部11は保持
に必要寸法まで小さくしている。If the width of the insulator 9 is equal to the width of the ferrite 10, insulation can be secured, so the insulator 9 is made as narrow as possible, and the hook portion 11 is made as small as necessary for holding.
上記構成によれば、誘導コイル５を保持するために、従
来例で説明したように誘導コイル５全体を覆う大きな部
品が必要でなく、また、小さい絶縁体９で誘導コイル５

の材料が使用されていなく、従来と同じ機能が得られる
ものである。According to the above configuration, in order to hold the induction coil 5, a large component that covers the entire induction coil 5 is not required as described in the conventional example, and the induction coil 5 is small with the small insulator 9.
Since the insulation of the ferrite 10 is maintained, unnecessary materials are not used, and the same function as the conventional one can be obtained.
なお、本実施例では、フェライト10を保護枠底部３−ａ

−ａに固定して誘導コイル５を保持しても良い。In this embodiment, the ferrite 10 is used as the protective frame bottom portion 3-a.
Although the hook portion 11 is provided as a method for fixing the ferrite 10 to the above, an adhesive may be used to fix the ferrite 10, and as shown in FIG.
The induction coil 5 may be held by being fixed to −a.
発明の効果 以上実施例の説明から明らかなように本発明によれば、
保護枠底部と絶縁体を介したフェライトで誘導コイルを
部分的に挟持することにより、誘導コイル全体を覆うよ
うな大きな保持用の部品が不要となり、安価で簡単な構
成とすることができる。EFFECTS OF THE INVENTION As is clear from the above description of the embodiments of the present invention,
By partially sandwiching the induction coil between the protective frame bottom portion and the ferrite via the insulator, a large holding component for covering the entire induction coil is unnecessary, and an inexpensive and simple structure can be obtained.
