Wherein it is possible to which the through-hole 201 in the end face section for keeping two adjacent locating height different is interconnected.Referring to Fig.1 To Fig. 7, illustratively, in the present embodiment, installation end face 200 specifically includes two end face sections: first end face section 204 and second End face section 205, wherein offer a through-hole 201 in first end face section 204, a through-hole is offered in second end face section 205 201, height locating for first end face section 204 is lower than height locating for second end face section 205, due to first end face section 204 and the Height locating for biend section 205 is different, therefore, logical on the through-hole 201 and second end face section 205 in first end face section 204 Height locating for hole 201 is different.During installation, mounting post 10 can be first made to enter in the first cavity 203, then basis is actually subjected to The mobile mounting post 10 of the rated power asked, cooperates mounting post 10 and one of through-hole 201, for example, working as required electromagnetism When the rated power of furnace is larger, mounting post 10 can be made to match with the through-hole 201 in the lower first end face section 204 in present position It closes, interconnecting piece 101 is connect with the through-hole 201 in first end face section 204, therefore height locating for the coil panel 2 after installing Degree is higher, and distance of the coil panel 2 apart from cookware is closer, and magnetic moment is smaller, and therefore, rated power is larger.Herein locating for coil panel 2 Higher height is for the distance between bottom wall of bottom case 1, and height locating for coil panel 2 is higher, 2 distance of coil panel The distance of the bottom wall of bottom case 1 is bigger, and distance of the coil panel 2 apart from cookware is closer.When the rated power of required electromagnetic oven When smaller, the through-hole 201 in mounting portion 10 and the higher second end face section 205 in present position can be made to cooperate, by interconnecting piece 101 It is connect with the through-hole 201 in second end face section 205.Therefore height locating for the coil panel 2 after installing is lower, coil panel 2 Distance apart from cookware is larger, and magnetic moment is larger, and therefore, rated power is smaller.

It is more preferred, the junction smooth transition of first end face section 204 and second end face section 205.Wherein, first end face Through-hole 201 in section 204 can not be connected to the through-hole 201 in second end face section 205, can also be connected to, when connection, installation A big through-hole is formed in hole 202, height locating for a part of the through-hole is higher, and height locating for a part is lower, In It, can be by the way that by mounting post 10, mobile realization mounting post 10 and the different location of through-hole connect in the first cavity 203 when installation It connects, and then realizes the adjusting of coil panel height.

Certainly, the through-hole 201 in first end face section 204 may be two or more, in second end face section 205 Through-hole 201 or two or more.

In the present embodiment, mounting hole 202 is specially ellipse, and through-hole 201 is specially circle.Certainly, mounting hole 202 It can be the shapes such as circle, through-hole 201 or ellipse etc., the utility model is not construed as limiting this.

Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new The range of each embodiment technical solution of type.
