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

トが高くなるという問題があった。Problems to be Solved by the Invention In such a conventional rice cooker, the protective cover 6 is necessary to hold the induction coil 6 and maintain insulation between the induction coil 6 and the ferrite 7. Since it is provided so as to cover the entire protective frame bottom 3-a and the induction coil 5, it is a larger component than necessary, resulting in an increase in cost.
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、フェライトと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。The present invention solves the above problems and aims to provide a rice cooker in which the induction coil can be easily held and the ferrite and the induction coil can be insulated.
課題を解決するだめの手段
本発明は上記目的を達成するために、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 structure in which an induction coil is sandwiched between the bottom of a protective frame and ferrite with an insulator 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。Operation In the above configuration, the induction coil is held between the bottom of the protective frame only by a small insulator and ferrite.
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
ながら説明する。本実施例において、前述の同一構成部
品には同じ符号を付し、その説明は省略する。本実施例

されている。EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2. In this embodiment, the same components described above are given the same reference numerals, and their explanations will be omitted. The characteristic configuration of this embodiment lies in the mounting structure of the induction coil section. In other words, this induction coil 6 is connected to the pot 2 on the outer surface of the protective frame bottom 3-a.
The ferrite 10 is sandwiched between ferrite 10 via an insulator 9 made of synthetic resin or the like.
is held by a 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１ｏ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 insulator 9 has the same width as the ferrite 1o, insulation can be ensured, so it is made as narrow as possible, and the hook portion 11 is made small to the size necessary for holding.
上記構成によれば、誘導コイル６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
とフェライト１０の絶縁を保っているため、不必要な部
分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 6, there is no need for a large part that covers the entire induction coil 5 as explained in the conventional example, and the small insulator 9 can be used to hold the induction coil 5.
Since the insulation between the ferrite 10 and the ferrite 10 is maintained, unnecessary material is 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１Ｑを保護枠底部３−
ａに固定する方法としてフック部１１を設けているが
、フェライト１０の固定は、接着剤を用いてもよく、ま
た第３図に示すように、絶縁体１２でフェライト１ｏを
保護枠底部３− ａに固定して誘導コイル５を保持して
も良い。In addition, in this example, the ferrite 1Q is attached to the bottom of the protective frame 3-
Although the hook portion 11 is provided as a method for fixing the ferrite 1o to the protective frame bottom 3-a, the ferrite 10 may be fixed using an adhesive.Alternatively, as shown in FIG. The induction coil 5 may be held by being fixed at point 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シ、誘導コイル全体を覆うよ

成とすることができる。Effects of the Invention As is clear from the description of the embodiments, according to the present invention,
By partially holding the induction coil between the bottom of the protective frame and the ferrite via the insulator, there is no need for large holding parts that cover the entire induction coil, resulting in an inexpensive and simple configuration. .
