[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0032] Please refer to Figures 1-6 , the present utility model provides a technical solution for a middle frame structure and an induction cooker including the middle frame structure.

[0033] A middle frame structure, comprising:

[0034] A first frame body 1, the first frame body 1 includes a first upper connection end 2 and a first lower connection end 3;

[0035] The second housing 4 includes a second upper connection end 5 and a second lower connection end 6. The first upper connection end 2 is connected to the second lower connection end 6, and the first lower connection end 3 is connected to the second upper connection end 5.

[0036] Manufacturing the first housing 1 and the second housing 4 separately and then connecting them together has a lower cost than manufacturing them integrally from stainless steel.

[0037] The following is a connection method between the first housing 1 and the second housing 4.

[0038] On the lower side of the first housing 1, there is a first inner convex ring 7. On the upper side of the first housing 1, there is a first outer convex ring 8. One end of the first inner convex ring 7 is provided with a first upper connection piece 9, and the other end is provided with a first lower connection piece 10.

[0039] On the lower side of the second housing 4, there is a second inner convex ring 11. On the upper side of the second housing 4, there is a second outer convex ring 12. One end of the first inner convex ring 7 is provided with a second upper connection piece 13, and the other end is provided with a second lower connection piece 14.

[0040] The first upper connection piece 9 is located above the second lower connection piece 14, and the second upper connection piece 13 is located above the first lower connection piece 10. The first upper connection piece 9 and the second lower connection piece 14 are welded together, and the second upper connection piece 13 and the first lower connection piece 10 are welded together. Spot welding is selected for welding, thereby connecting the first housing 1 and the second housing 4 together.

[0041] To increase the connection strength between the first housing 1 and the second housing 4, one end of the first outer convex ring 8 is provided with a first groove 15, and the other end is provided with a first protrusion 16. One end of the second outer convex ring 12 is provided with a second groove 17, and the other end is provided with a second protrusion 18. The first protrusion 16 is inserted into the second groove 17, and the second protrusion 18 is inserted into the second groove 17. Both the first protrusion 16 and the second protrusion 18 are set as inverted trapezoids, and the shapes of the first groove 15 and the second groove 17 are also set as inverted trapezoids.

[0042] The insertion of the first protrusion 16 into the second groove 17 and the insertion of the second protrusion 18 into the second groove 17 can connect the first outer convex ring 8 and the second outer convex ring 12 together, increasing the overall strength.

[0043] The first outer convex ring 8 includes two first outer connection segments 19 and a first connecting member 20. One end of each of the two first outer connection segments 19 close to each other is provided with a first outer connection protrusion 21.

The first outer connection protrusion 21 is set as an inverted trapezoid, and the first outer connection groove 22 is also set as an inverted trapezoid.

[0044] Since the first outwardly convex ring 8 is divided into two first outer connecting segments 19, it is convenient for the processing of the first housing 1, but its strength will be affected. By connecting the two first outer connecting segments 19 together with the first connecting member 20, the connection strength can be increased.

[0045] Similarly, the second outwardly convex ring 12 includes two second outer connecting segments 24 and a second connecting member 27. Second outer connecting protrusions 25 are provided at one end of the two second outer connecting segments 24 close to each other.

A second welding protrusion 28 is also provided on the second connecting member 27. The second welding protrusion 28 is welded to the second housing 4. The second outer connecting protrusion 25 is arranged in an inverted trapezoid shape, and the second outer connecting groove 26 is also arranged in an inverted trapezoid shape.

[0046] Similarly, the second connecting member 27 connects the two second outer connecting segments 24 together, which can increase the connection strength.

[0047] The materials of the first housing 1 and the second housing 4 are set as cold-rolled plates. Since the surface of the cold-rolled plate material has good processing performance, subsequent spraying and other processing techniques can be carried out.

[0048] An induction cooker is also disclosed, which includes the above middle frame structure.
