<p><P>PROBLEM TO BE SOLVED: To provide an induction heating cooking appliance which efficiently cools a circuit board and heating coils set above the circuit board with less wind volume. <P>SOLUTION: The induction heating cooking appliance includes heating coils 20a and 20b heating a cooking pot by electromagnetic induction, the circuit board 43 supplying high-frequency currents to the heating coils 20a and 20b, a partition 90 partitioning a space in which the heating coils 20a and 20b are placed from a space in which the circuit board 43 is placed, a first fan 5a cooling the heating coils 20a and 20b, a heat receiving unit 31 taking heat away from an electronic component 41 mounted on the circuit board 43, and a liquid cooling system consisting of a water feeding means 33 feeding a liquid to the heat receiving unit 31 and a heat exchanger 30 exchanging heat between the liquid and air. The heat exchanger 30 is provided with a second fan 5b, and the first fan 5a cools the circuit board 43 and the heating coil 20 and the second fan 5b cools the heat exchanger 30. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
