In order to improve the heating effect of the coil panel on the side wall of the pot, the inventor thinks that a double-side winding mode is adopted for winding, so that the heating height after being coupled with the pot can be improved, and the side wall of the pot can be effectively heated.
But the shielding metal piece is in contact with the winding or has a small gap, and is generally a complete metal plate without holes, when the coil panel is electrified and works, the winding can generate heat, the shielding metal piece can prevent convection of air with low temperature and the winding, and the heat exchange effect between the winding and the outside is poor, so that the heat dissipation of the coil panel is poor.
In order to solve the above problems, the present utility model provides a shielding member, a wire coil assembly and a cooking apparatus, and fig. 1 to 4 illustrate an embodiment of a coil assembly according to the present utility model.
Referring to fig. 1 to 3, the shielding member 100 is used in a wire coil assembly 1000, and is configured to be mounted on a second side of a bracket 200 of the wire coil assembly 1000, and a plurality of second wire segments 312 located on the second side of the bracket 200 are located on a side opposite to the bracket 200, the shielding member 100 includes a main body 1, the main body 1 is configured to be mounted on the second side of the bracket 200, and an opening 11 is provided on the main body 1.

Further, the number and arrangement manner of the openings 11 are not limited, so long as it is ensured that the openings 11 can promote convection between air with a lower temperature and the wire coil assembly 1000, so as to reduce the temperature of the wire coil assembly 1000, for example, in this embodiment, as shown in fig. 1, the openings 11 are provided in a plurality, and the more the number of the openings 11, the more cold air that can generate convection with the wire coil assembly 1000, the better the heat exchange effect between the wire coil assembly 1000 and the outside, so that the better the heat dissipation effect of the wire coil assembly 1000. Meanwhile, the plurality of openings 11 are distributed at least along the circumferential direction of the main body 1, so that the plurality of openings 11 are distributed more uniformly, and as shown in fig. 5, the cool air can be convected with the wire coil assembly 1000 uniformly.
