Abstract (en)
[origin: EP3267766A1] An induction heating cooker includes a drive circuit, multiple heating coils, and relay circuit (31). The drive circuit converts an AC power supply to high-frequency electric power. The multiple heating coils are disposed to metallic shielding plate (24), and generate a high-frequency magnetic field upon receiving the high-frequency electric power. The relay circuit includes multiple relays (32) that switch the connections, in response to a signal supplied from the drive circuit, between the drive circuit and the multiple heating coils, and is coupled to the heating coils via connection wire (27). Relay circuit (31) is mounted to holder (26) provided to shielding plate (24) on a face opposite to a face where the heating coils are provided. The structure discussed above allows a wiring work to be done firstly between relay circuit (31) and the heating coils, and then allows a wiring work to be done between relay circuit (31) and the drive circuit. As a result, noises can be reduced, and this induction heating cooker can be assembled more efficiently. On top of that, the number of components to be commonly used in other models can be increased.
