Embodiment Construction

[0048] Embodiments of the present invention will be described below with reference to the drawings.

[0049] 1 to 7 show an embodiment of the present invention, showing a built-in type induction heating cooker in which three pot placement parts 73a, 73b, and 73c are provided on a top plate 70. As shown in FIG.

[0050] In addition, this invention is not limited to this structure, The induction heating cooker which provided the pan placement part of at least one induction heating may be sufficient. In addition, it is not a built-in type installed in the kitchen, but a shelf type induction heating cooker placed in the kitchen is fine.

[0051]FIG. 1 shows a state in which the top plate 70 is detached from the induction heating cooker main body 9 of the present embodiment. The induction heating cooker of this embodiment is provided with: the pot placement parts 73a, 73b that supply the heating coil 20 with high-frequency current to inductively heat the cooking pot (not shown) ar...

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...
