Description

Technical Field

[0001] The utility model relates to the technical field of induction cookers, in particular to an ultra-thin induction cooker. Background Art

[0002] Induction cookers mainly use the alternating magnetic field generated by the electromagnetic wire coil for heating. In order to generate an alternating magnetic field, a high-frequency alternating current needs to be passed into the electromagnetic wire coil, which requires the use of switching elements such as IGBT to control the current passing into the electromagnetic wire coil. This will cause the IGBT, electromagnetic wire coil and other components to generate high heat, so it is necessary to design a corresponding heat dissipation structure on the induction cooker. At present, the mainstream ultra-thin induction cookers on the market have smaller air inlet and outlet spaces due to their thinner thickness, and the heating area of ​​the electromagnetic wire coil is larger, which requires a large range of overall heat dissipation. Using a single fan to concentrate the circuit board and the electromagnetic wire coil in one area for heat dissipation will result in incomplete heat dissipation and a rapid decline in the performance of the heating element, thus affecting the life of the entire machine.
