In addition, because the first ventilation holes 110 are arranged close to the front side of the induction cooker, the pan placed on the induction cooker panel 10 is far away from the first ventilation holes 110, even if the pan overflowing phenomenon occurs, the soup overflowing from the pan is not easy to flow into the inner cavity of the bottom case 1 from the first ventilation holes 110, so that the devices in the induction cooker are effectively protected to a certain extent, and unsafe accidents are avoided.

In particular, the power strip assembly 3 may be disposed on the front side wall section. Through setting up power board subassembly 3 on front side wall section, not only effectively saved the space in the drain pan 1, make simultaneously that the cooling wind in the heat dissipation wind channel between first ventilation hole 110 and cooling fan 4 can be more concentrated blow to power board subassembly 3.
