The adjacent coil support parts 412 are hollowed out.

In the above solution, the coil 401 that is spirally wound to form several concentric circles is beneficial to generate a uniform magnetic field, so as to achieve uniform heating of the water box 510 . The first mounting plate 410 used to support the coil 401 has a hollow structure, which can increase the contact area between the coil 401 and the air, thereby facilitating heat dissipation during the power-on period of the coil 401, and avoiding the failure of the electromagnetic heating module 400 caused by the overheating of the coil 401, which affects the use.

In this embodiment, a first fixed disk 413 is provided at the central part of the first mounting disk 410 , and the extended end of the coil support portion 412 is connected to the first fixed disk 413 .
