In order to improve the usability of the induction heating cooker by making it possible to use the pan at a lower position, the gap between the pan 6 and the heating coil 3 or the control circuit 4 becomes smaller, and the pan 6 or the heating coil 3 is added to the control circuit 4. The heat effect from the power supply increased, which could cause malfunctions and failures in the control circuit components.
そこで、本発明は本体を薄型化しても制御回路が誤動作

き、薄型、高密度実装が可能になる。According to the above-described configuration, the heat shield plate shields the radiant heat from the pan and the heating coil so that it is not transmitted to the control circuit side, and the cooling air does not flow below the heating coil, but is arranged on the outer circumference of the heating coil. Since it flows only to the control circuit board, the cooling air is hardly heated by the radiant heat from the cooking pot or the heating coil, the control circuit components can be efficiently cooled, and thin and high-density mounting is possible.

る。In FIGS. 1 and 2, 7 is a cooker body, 8 is a cooking plate, and 9 is a heating coil. 10 is a heating coil 9
The control circuit board is provided with a control circuit component 22 for supplying a high-frequency current to the heating coil 9 and is arranged around the heating coil 9.
11 is a cooling fan. Reference numeral 12 is a non-metal heat shield plate disposed above the control circuit board 10. Front edge 13 of heat shield 12
Faces the discharge port 14 of the cooling fan 11 to allow the cooling air to flow into the lower part of the heat shield plate 12, and the rear end 15 thereof faces the exhaust port 16 of the cooker body 7. Also a heat shield
The inner end 17 of 12 is in contact with the support 18 of the heating coil 9, and the outer end 19 is in contact with the body side wall 20. 21 is a cooking pot.
以上のように構成された本実施例の動作を第３図に基づ

る。The cooling air that has flowed into the lower part of the heat shield plate 12 from the discharge port 14 of the cooling fan 12 flows in the ventilation passage composed of the heat shield plate 12 on the upper surface, the heating coil support 18 on the side surface, and the main body side wall 20, and controls the inside. After the circuit component 22 is cooled, it is discharged from the exhaust port 16. At this time, the radiant heat from the cooking pot 21 and the heating coil 9 is shielded by the heat shield plate 12, and the control circuit component 22 is less likely to be affected by the temperature rise.
以上の構成であれば遮熱板12の密閉を良くし、断熱性を
増していくことにより、より高密度な実装が可能とな
り、調理器本体の薄型化、小型化が図れる。With the above configuration, the heat shield plate 12 can be hermetically sealed and the heat insulating property can be increased, so that higher density mounting can be achieved, and the cooker main body can be made thinner and smaller.
次に本発明の他の実施例を第４図により説明する。Next, another embodiment of the present invention will be described with reference to FIG.
第４図において遮熱板25の周囲にはフランジ部23,24が

効果が減少するのを防ぐことができる。In the present embodiment, the heat shield plate is made of a non-metallic material, so that it is possible to prevent the heat shield plate itself from generating heat due to the lines of magnetic force and the heat shield from reducing the shield effect.

り、調理器本体の薄型化、小型化が図れる。According to the present invention, the control circuit board is arranged on the outer periphery of the support of the heating coil, and the heat shield plate for shielding the heat from the cooking pot on the upper surface of the heating coil is arranged on the upper surface of the control circuit board. Since a ventilation duct that guides the cooling air from the cooling fan to the exhaust port through the outer circumference of the heating coil is constructed by the heat shield plate, the cooling air from the cooling fan does not flow below the heating coil, and is placed on the outer circumference of the heating coil. Since it flows only to the circuit board, the cooling air is hardly heated by the radiant heat from the cooking pot or heating coil, the cooling efficiency by the cooling air can be improved, and high-density mounting can be achieved. Since there is no control circuit component that is easily affected by heat, it becomes possible to dispose the heating coil close to the bottom surface of the cooker body, and the cooker body can be made thinner and smaller.
