Example Embodiment

[0048] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0049] Figs. 1 to 7 show an embodiment of the present invention, and show a built-in type induction heating cooker in which a top plate 70 is provided with three pot placement portions 73a, 73b, and 73c.

[0050] In addition, the present invention is not limited to this structure, and may be an induction heating cooker provided with at least one induction heating pot placement portion. In addition, it does not matter if it is a built-in type built into the kitchen but a shelf type induction heating cooker placed in the kitchen.

[0051]Fig. 1 shows a state where the top plate 70 is removed from the induction heating cooker main body 9 of this embodiment. The induction heating cooker of this embodiment is provided with pot placement portions 73a, 73b which are arranged on the left and right sides of the main body 9 to supply heating coils 20 with high-frequency current to inductively...

Abstract

The present invention provides an induction heating cooker having a cooling mechanism for heating metal cooking pot by supplying high frequency current to heating winding, a circuit substrate capable of cooling the induction heating cooker in high frequency with low blast volume and a heating winding arranged upside of the same, and kitchen condition supplying low noise. The invention comprises a heating winding arranged under the top plate for heating the cooking pot; a circuit substrate for supplying high frequency current to the heating winding; a fan device for supplying cooled air; a liquid cooling system having heat exchanger operating heat exchange with said electronic member of said circuit substrate with liquid and air; and air passage guiding the air supplied to said circuit substrate from said fan device to at least said heat exchanger.

Description

technical field [0001] The present invention relates to a cooling structure of an induction heating cooker for heating a metal cooking pot by supplying a high-frequency current to a heating coil. Background technique [0002] Induction heating is to supply high-frequency current to the heating coil arranged under the cooking pot, use the magnetic field generated around the heating coil to generate eddy current near the surface of the cooking pot, and use the Joule heat to heat the cooking pot itself for heating and cooking. [0003] In addition, in induction heating, the heating efficiency of the cooking pot varies depending on the material of the cooking pot (relative magnetic permeability or resistivity). Larger, the heating efficiency is also good as θ > 90%, but the heating efficiency is low for aluminum pots or copper pots with low resistivity. [0004] Therefore, with respect to the power supplied to the heating coil, a cooking pot with a smaller resistivity does n...
