DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 6 As shown, an embodiment of the present invention provides an induction cooker, comprising: an induction cooker body 1; a spliced ​​heating plate 2 arranged on one side of the induction cooker body 1, the spliced ​​heating plate 2 comprising a plurality of spliced ​​heating blocks 21; an elastic support frame assembly 3 arranged on the side of the heating block 21 facing the induction cooker body 1, the elastic support frame assembly 3 being connected to each heating block 21 and the induction cooker body 1, so as to provide a reset force for any heating block 21 when the heating block 21 moves toward the side of the induction cooker body 1.

[0032] In the above-mentioned induction cooker, Figures 1 to 6As shown, the heating plate of the induction cooker is a spliced ​​heating plate 2, and the spliced ​​heating plate 2 is formed by splicing a plurality of heating blocks 21, each heating block 21 is independent, and a certain gap can be set between each adjacent heating block 2, and the spliced ​​heating plate 2 is provided with an elastic support frame assembly 3 corresponding to each heating block 21 and used to support each heating block 21 on the side facing the induction cooker, the top side of the elastic support frame assembly 3 is connected to each heating block 21 and the bottom is fixed to the induction cooker body 1, so as to provide a reset force for the heating block 21 when any heating block 21 moves toward the side of the induction cooker body 1, each heating block 21 can move toward the bottom of the induction cooker body, and the moving distance of any two heating blocks 21 can be different, when the above-mentioned induction cooker is used in conjunction with a frying pan, the bottom surface of the frying pan is in contact with the surface of the spliced ​​heating plate 2, and due to the frying pan The bottom surface is a plane, so the force is evenly applied to the surface of the spliced ​​heating plate 2. The surface of the spliced ​​heating plate 2 is also a plane that supports the frying pan and is in full contact with the bottom surface of the frying pan, so the heating is even. When the above-mentioned induction cooker is used in conjunction with the round-bottomed pan, since the bottom of the round-bottomed pan is a curved surface, when placed on the above-mentioned induction cooker, the heating blocks 21 of the induction cooker are unevenly applied, so the distances by which the heating blocks 21 move away from the round-bottomed pan are different, that is, the distances by which the heating blocks 21 are pressed downward by the round-bottomed pan are different. Each heating block 21 will adapt to the bottom surface of the round-bottomed pan and cooperate with the bottom surface of the round-bottomed pan to deform the spliced ​​heating plate 2 and form a depression. The surface of the spliced ​​heating plate 2 forms a concave surface that cooperates with the bottom surface of the round-bottomed pan, fits with the bottom surface of the round-bottomed pan, has a large contact area, and has good contact, so that the round-bottomed pan is heated evenly, the phenomenon of cooking pot sticking is reduced, and the utilization rate of electric energy can also be effectively improved.

[0033] The spliced ​​heating plate 2 of the induction cooker includes a plurality of independent heating blocks 21. An elastic support frame assembly 3 is provided on the side of each heating block 21 facing the induction cooker body 1. Each heating block 21 can move toward the side of the induction cooker body 1, so that the spliced ​​heating plate 2 can be deformed and can be adapted to a flat pan or a round bottom pan, so as to fit the bottom surface of the round bottom pan and increase the contact area with the round bottom pan, so that the round bottom pan is heated evenly, effectively reducing the phenomenon of sticking during cooking, and effectively improving the utilization rate of electric energy.

[0034] Among them, Figure 4 As shown, each heating block 21 in the above-mentioned splicing type is set as an equilateral triangle heating block 21. When the equilateral triangle heating blocks are spliced, the overall surface of the splicing type heating plate can have no excessive gaps or vacancies, and the equilateral triangle heating blocks have a good fit. When the adjacent heating blocks are subjected to different forces, the deformation curved surface formed by the cooperation between the heating blocks has a smoother arc, which can better match the bottom side surface of the round bottom pot. Among them, each heating block 21 can also be round or square, which is not limited to this embodiment.

[0035] As shown in the figure, there are many options for setting the elastic support frame assembly 3, such as:

[0036] Method 1:

[0037] like Figures 5 to 7 As shown, the elastic support frame assembly 3 includes a triangular supporting plate 31 corresponding to each heating block 21 and used to support the heating block 21. In each triangular supporting plate 31, each adjacent two triangular supporting plates 31 are symmetrically arranged, and each corner of each triangular supporting plate 31 is provided with an elastic supporting column 32 for supporting the triangular supporting plate 31. The top end of the elastic supporting column 32 is connected to the corner of the triangular supporting plate 31 and the bottom end is fixed to the induction cooker body 1, so as to provide a reset force for the heating block 21 when the heating block 21 moves toward the side of the induction cooker body 1.

[0038] The elastic support frame assembly 3 includes a triangular support plate 31 corresponding to each heating block and an elastic support column 32 for supporting each corner of the triangular support plate 31. The triangular support plate 31 is an equilateral triangle corresponding to the heating block 21. The heating block 21 is mounted on the triangular support plate 31. A plurality of triangular support plates 31 also form a splicing relationship. Each adjacent two triangular support plates 31 spliced ​​together are symmetrically arranged. For example, Figure 4 In the figure, with B as a reference, C is adjacent to B and symmetrical to B, D is adjacent to B and symmetrical to B, and E is adjacent to B and symmetrical to E. According to such a splicing relationship, that is, among the multiple triangular supporting plates 31, six triangular supporting plates 31 distributed around a corner of one of the triangular supporting plates 31 form a regular hexagon, and the heating block 21 corresponds to the triangular supporting plate 31 one by one, then the splicing method of the heating block 21 is the same as the splicing method of the triangular supporting plate 31. In addition, each of the three corners of the triangular supporting plate 31 is provided with an elastic support column 32, which can support the triangular supporting plate 31, and the elastic support column 32 has a certain toughness. When the three When the corner bearing plate 31 is subjected to force to press the elastic support column 32 downward, the elastic support column 32 bends to adjust the downward movement distance of the triangular bearing plate 31, and when the three corners of the triangular bearing plate 31 are subjected to different forces, the corresponding elastic support columns 32 bend to different degrees, so that the triangular bearing plate 31 can be moved downward and tilted, that is, each heating block 21 can be moved downward and tilted to match the bottom surface of the round bottom pot. When the force on the triangular bearing plate 31 is cancelled, each elastic support column 32 returns to its initial state, so that the multiple triangular bearing plates 31 return to a flush state. The above-mentioned use of elastic support columns to support each of the triangular bearing plates 31 is stable and easy to set up.

[0039] In the above method 1, if Figure 5 and Figure 7As shown, the elastic support column 32 is an elastic rod, one end of which is connected to the corner of the triangular supporting plate 31, and the other end is fixed to the induction cooker body 1. Specifically, the material of the elastic rod can be metallic glass, or other materials that have certain elasticity and toughness and can play a role, and this embodiment is not limited thereto.

The six elastic rods distributed around a corner of the triangular bearing plate 31 can be bundled together by metal wires to form a column to jointly support the six corners of the six triangular bearing plates 31 corresponding to the main body, and the column is still elastic and capricious, and can be bent when subjected to force, without affecting the downward movement of the triangular bearing plate 31, and because Each triangular supporting plate 31 is spliced ​​together, and the stress conditions of the six elastic rods distributed around a corner of the triangular supporting plate 31 are the same. The six elastic rods distributed around a corner of the triangular supporting plate 31 can be bundled together by metal wire, so that each elastic support frame is connected into a stable support structure, which is beneficial to increase the stability of the elastic support frame supporting the heating block 21, and the top of each elastic rod is bent toward the center of the corresponding triangular supporting plate 31 to form a bending portion, and the inclination direction of the triangular supporting plate 31 can be fine-tuned to better fit the bottom surface of the round-bottomed pot.

[0041] In the above-mentioned method 1, each side of each triangular supporting plate 31 can be provided with a curved edge recessed toward the center of the triangular supporting plate 31, and the line connecting the three corners of the triangular supporting plate 31 with the curved edge is still an equilateral triangle. This arrangement reduces the volume of the triangular supporting plate 31, reduces the load of the elastic support column 32, and will not affect the bearing effect on the heating block 21.

[0042] Method 2:

[0043] Combination Figure 1 ,like Figure 8 and Fig. 9As shown, the elastic support frame assembly includes a triangular supporting plate 31 corresponding to each heating block 21 and used to support the heating block 21, and an elastic supporting assembly 33 for supporting the triangular supporting plate 31.
