Below the heating coils, inverter circuits 5 for supplying high-frequency power to the respective heating coils are arranged. Behind the inverter circuit 5, the inverter circuit 5, first and second heating coils 2 and 3 are forcibly cooled. For this purpose, a first cooling fan 10 is arranged (see, for example, Patent Document 1).

以下、本発明の実施の形態について図面を参照しながら説明する。なお、この実施の形態によっては本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited by this embodiment.

（実施の形態１）
図１は、本発明の第１の実施の形態における誘導加熱調理器の構成を示す図である。図２は、本発明の第１の実施の形態における誘導加熱調理器の全体図を表している。 (Embodiment 1)
FIG. 1 is a diagram showing a configuration of an induction heating cooker according to the first embodiment of the present invention. FIG. 2 shows an overall view of the induction heating cooker according to the first embodiment of the present invention.

図２に示すように、本体の天面はガラスなどの非金属で構成された平坦な天板７が置かれ、調理物が入った鍋などの負荷が置かれる。天板７の下部には約１０ｍｍほどの空間を介して鍋などの負荷に誘導加熱を行うための加熱コイルが配置される。加熱コイルは、本体の前方の左右に配置される第１の加熱コイル２と第２の加熱コイル３が配置され、更に第１の加熱コイル２と第２の加熱コイル３の後方の中央付近に第３の加熱コイル４が配置される（以下中央ヒータ）。通常、使用者が調理し易い様に、前方に配置される第１及び第２の加熱コイル２、３は後方に配置される第３の加熱コイル４よりも直径が大きく、火力の強いものが配置される。それぞれの加熱コイルには加熱コイルに高周波電力を供給するインバータ回路５が接続され、インバータ回路５の後方には、インバータ回路５、第１の加熱コイル２、第２の加熱コイル３を冷却するための第１の冷却ファン１０が配置される。また、第３の加熱コイル４の近傍には、第３の加熱コイル４を冷却する第２の冷却ファン１３が配置される。ここで、中央ヒータとして用いる第３の加熱コイル４の外径を、図４に記載の電気ヒータ６の外形と概同径とすることにより機種間での置き換えを簡易に行うことができる。   As shown in FIG. 2, a flat top plate 7 made of a nonmetal such as glass is placed on the top surface of the main body, and a load such as a pan containing food is placed. A heating coil for performing induction heating on a load such as a pan through a space of about 10 mm is disposed below the top plate 7. As for the heating coil, the first heating coil 2 and the second heating coil 3 arranged on the left and right in front of the main body are arranged, and further, in the vicinity of the center behind the first heating coil 2 and the second heating coil 3. The 3rd heating coil 4 is arrange | positioned (henceforth a center heater). Usually, the first and second heating coils 2 and 3 disposed in the front are larger in diameter and stronger than the third heating coil 4 disposed in the rear so that the user can easily cook. Be placed. Each heating coil is connected to an inverter circuit 5 that supplies high-frequency power to the heating coil, and the inverter circuit 5, the first heating coil 2, and the second heating coil 3 are cooled behind the inverter circuit 5. The first cooling fan 10 is arranged. A second cooling fan 13 that cools the third heating coil 4 is disposed in the vicinity of the third heating coil 4. Here, when the outer diameter of the third heating coil 4 used as the central heater is approximately the same as the outer diameter of the electric heater 6 shown in FIG. 4, replacement between models can be easily performed.

また、図１に本実施の形態での誘導加熱ヒータ、電気ヒータ６を使う場合の構成を示す図を記載する。図１に示すように、電気ヒータ６を用いる場合には電源部１６からの電源をリレー手段９を介して電気ヒータ６に接続する構成を取る。制御手段８は、操作部１４で設定された電力量になるようにリレー手段９を入り切りすることで、電気ヒータ６の電力量を制御することになる。一方、誘導加熱ヒータを用いる場合においては、天板７上に置かれた鍋などの負荷に高周波電力を供給するための誘導加熱コイル１とインバータ回路５が配置され、同じく操作部１４で設定された電力量になるように制御手段８はインバータ回路５を制御することになる。この際、リレー手段９をオン状態にしインバータ回路５内のスイッチング素子を制御することにより、誘導加熱の特性を活かしたきめ細やかな制御を行うことができるとともに、制御手段８を共用化することができるため、部品を共用化することができ安価な構成をとることが可能となる。   FIG. 1 is a diagram showing a configuration in the case of using the induction heater and electric heater 6 in the present embodiment. As shown in FIG. 1, when the electric heater 6 is used, the power supply from the power supply unit 16 is connected to the electric heater 6 through the relay unit 9. The control means 8 controls the electric energy of the electric heater 6 by turning on and off the relay means 9 so that the electric energy set by the operation unit 14 is obtained. On the other hand, when an induction heater is used, an induction heating coil 1 and an inverter circuit 5 for supplying high-frequency power to a load such as a pan placed on the top plate 7 are arranged, and are also set by the operation unit 14. The control means 8 controls the inverter circuit 5 so that the amount of electric power is increased. At this time, by controlling the switching element in the inverter circuit 5 by turning the relay means 9 on, fine control utilizing the characteristics of induction heating can be performed, and the control means 8 can be shared. Therefore, parts can be shared and an inexpensive configuration can be achieved.

一方、誘導加熱バーナにおいてもリレー手段９の入り切りで電力制御を行うことにより、インバータ回路５の電力制御を簡易にすることができるためより安価の構成をとることもできる。また、火力設定値も同一とすることにより表示及び操作部を同一設計とすることができるため、部品を共用化することができ安価な構成をとることが可能となる。   On the other hand, in the induction heating burner, the power control of the inverter circuit 5 can be simplified by performing the power control with the relay means 9 turned on and off, so that a cheaper configuration can be taken. Moreover, since the display and the operation unit can be designed to be the same by setting the same thermal power setting value, the parts can be shared and an inexpensive configuration can be achieved.

一方、図３では、誘導加熱バーナ時と電気ヒータ時の火力設定を変えている場合の例を示している。この際、低電力側（４００〜１２００Ｗ設定）の加熱電力量及び表示を共通化し、誘導加熱バーナ時のみの高火力（１５００Ｗ設定）とし、電気ヒータ時は設定値以上上がらない設定とすることにより、表示部を共用化することが可能となる。   On the other hand, in FIG. 3, the example in the case of changing the heating power setting at the time of induction heating burner and at the time of an electric heater is shown. At this time, the heating power amount and the display on the low power side (400 to 1200 W setting) are made common, the heating power is set only for the induction heating burner (1500 W setting), and the electric heater is set so as not to exceed the set value. The display unit can be shared.

なお、本実施の形態では３口の誘導加熱装置の関して記載しているがバーナの口数に関しては特に限定するものではない。但し、本実施の形態の様に複数のバーナが存在している場合においては、ヒータの外径が小さいまたは火力が小さい物を共用化できる様にした方が載せ替えのための共用スペースを小さくすることができるため、望ましい。   In addition, in this Embodiment, although described regarding the induction heating apparatus of 3 necks, it does not specifically limit regarding the number of burners. However, in the case where a plurality of burners are present as in the present embodiment, it is possible to reduce the common space for replacement by making it possible to share a heater with a small outer diameter or a small heating power. Because it can be desirable.

以上のように、本実施の形態においては、操作部１４と、誘導加熱コイル１と、誘導加熱コイル１に接続されたインバータ回路５と、誘導加熱コイル１が操作部１４で設定された火力になるようにインバータ回路５を制御する制御手段８を備え、制御手段８は、電気ヒータ６が操作部１４で設定された火力になるようにリレー手段９を制御することもできる様にすることにより、誘導加熱ヒータを用いる場合と電気ヒータ６を用いる場合で制御回路の設計等を大きく変える必要がなくなるため、部品を共用化することができ安価で使い勝手の良い誘導加熱調理器を実現できるものである。   As described above, in the present embodiment, the operation unit 14, the induction heating coil 1, the inverter circuit 5 connected to the induction heating coil 1, and the heating power set by the operation unit 14 Thus, the control means 8 for controlling the inverter circuit 5 is provided so that the control means 8 can also control the relay means 9 so that the electric heater 6 becomes the heating power set by the operation unit 14. Since it is not necessary to change the design of the control circuit greatly between the case of using the induction heater and the case of using the electric heater 6, the parts can be shared and an inexpensive and easy-to-use induction heating cooker can be realized. is there.

以上のように、本発明にかかる誘導加熱調理器は、部品を共通化することができるため、安価で使い勝手の良い調理器を実現することができる。誘導加熱を行う一般家庭やレストラン及びオフィスなどで使用される加熱調理器等の用途にも適用できる。   As described above, since the induction heating cooker according to the present invention can share parts, an inexpensive and easy-to-use cooker can be realized.
