The magnetic member 150 may function to change the magnetic field strength and the direction of the local magnetic field strength. The magnetic member 150 may be made of a soft magnetic ferrite material and/or a manganese-zinc ferrite material. The coil disk and the magnetic member 150 are respectively disposed at both sides of the coil support 110 facing away from each other. Specifically, the coil disk is disposed at a side of the coil support 110 facing the pot, and the magnetic member 150 is disposed at a side of the coil support 110 facing away from the pot.

The first center line 137 forms an angle of 0 ° or more and 45 ° or less with the second center line 111.

In this embodiment, the projection of the thermostat 130 on the horizontal plane has a non-perfect circle shape, such as any one of an ellipse, a rectangle, a square, and an ellipse with cut edges. That is, the shape of the first projection may be any one of a non-perfect circle, such as an ellipse, a rectangle, a square, and an ellipse having a cut edge. When the first projection is a regular geometric figure, the center of the first projection is the geometric center. When the first projection is an irregular figure, the center of the first projection is the intersection point of the connecting line of the two points which are farthest away from each other in the circumferential direction and the connecting line of the two points which are farthest away from each other in the radial direction and serves as the center.

The first and second mounting parts cooperate with each other to reliably connect the thermostat bracket 131 to the coil bracket 110. It is worth to be noted that the transition section, the near pot section and the far pot section which form the temperature controller support 131 are of an integrated structure, and specifically, the temperature controller support 131 can be manufactured by an injection molding process.

In this embodiment, the coil disk assembly 100 further includes a plurality of magnetic members 150, and the plurality of magnetic members 150 are arranged at intervals on a side of the coil support 110 facing away from the coil disk. By providing a plurality of magnetic members 150, it is possible to adapt to the spatial arrangement requirements. On the premise of meeting the requirement of the magnetic field intensity, the magnetic pieces 150 can be matched and arranged to be suitable for the remaining space position of the coil support 110. If the magnetic member 150 is a whole, when the magnetic member 150 is assembled on the coil support 110, the arrangement of other components will make it difficult to satisfy the large assembling space required by the magnetic member 150 because the electromagnetic heating device further includes other components.

Further, as shown in fig. 5, the plurality of magnetic members 150 includes a first magnetic member 151 and a second magnetic member 152 that are oppositely disposed, a portion of the thermostat 130 is located in a gap between the first magnetic member 151 and the second magnetic member 152, and a distance between the first magnetic member 151 and the second magnetic member 152 is greater than a length of the third centerline 138.

Thereby, the splicing among the plurality of magnetic members 150 can be facilitated, and the close arrangement of the plurality of magnetic members 150 can be realized in a limited space. Further, each magnetic member 150 includes at least one pair of first and second magnetically conductive sidewalls disposed opposite to each other.
