[0018] The above-mentioned objectives, features, and other advantages of the present invention will become more apparent by describing preferred embodiments of the present invention in detail with reference to the accompanying drawings. Hereinafter, an induction heating plate according to an embodiment of the present invention will be described in detail with reference to the attached drawings.

[0019] FIG. 1 is a perspective view illustrating an induction heating plate according to a first embodiment of the present invention, FIG. 2 is a side view illustrating a state in which an induction container is placed on an induction heating plate according to a first embodiment of the present invention, FIG. 3 is a side view illustrating a state before and after an induction container is placed on an induction heating plate according to a first embodiment of the present invention in which an elastic body is provided between a connecting part and a magnetic piece, FIG. 4 is an exploded perspective view illustrating an induction heating plate according to a second embodiment of the present invention, FIG. 5 is a side cross-sectional view illustrating a state in which an induction container is placed on an induction heating plate according to a second embodiment of the present invention, and FIG. 6 is a plan view illustrating an induction heating plate according to a third embodiment of the present invention.

[0020] Referring to FIGS. 1 to 3, an induction heating plate (100) according to the first embodiment of the present invention includes a connecting part (110) and a magnetic piece (120).

[0021] As shown in FIGS. 1 to 3, the connecting part (110) is provided to transfer heat from the induction cooker to the induction container (10) using electromagnetic waves generated from the induction cooker, and is provided as a heating plate which is a conductor for transferring heat, having a mesh structure.

[0022] Furthermore, although the connecting part (110) was exemplified as having a mesh structure, it is not limited thereto and can be modified to a perforated plate having a perforated structure, and other materials such as a silicone plate can also be applied.

[0023] At this time, the connecting part (110) is provided with a mesh made of, for example, a material such as stainless steel, and is provided with a mesh to prevent deformation caused by the heat of the induction cooker.

[0024] As shown in FIGS. 1 to 3, a plurality of magnetic pieces (120) are fixed on the connecting part (110) to increase the contact area with the induction container (10) that contacts the upper part, and are configured to conduct heat to the induction container (10).

[0025] For example, the magnetic piece (120) can be fixed on the connecting part (110) by welding, rivet, screw (bolt) and nut, snap fastener, etc., but is not limited to these and can be fixed by various methods.

[0026] At this time, the magnetic body piece (120) is provided in a plate structure such as a circle or polygon, which is smaller than the size of the connecting part (110). Also, the magnetic body piece (120) can be perforated.

[0027] In this way, since the magnetic piece (120) is provided to be small in size, it is possible to prevent bending or warping caused by the heat of the induction cooker, just like the connecting part (110).

[0028] Meanwhile, referring to FIG. 3, the lower part of the magnetic piece (120) can be fixed by an elastic body (130) that is fixed at the upper part of the connecting part (110).

[0029] At this time, the elastic body (130) may be a coil spring or a plate spring with a convex arc structure. Furthermore, the upper part of the elastic body (130) can be fixed by bending it in a partially cut state or through a plurality of perforations formed on the bottom surface of the magnetic body piece (120).

[0030] In this way, when the magnetic body piece (120) and the connecting part (110) are connected through the elastic body (130), the contact area between the bottom of the induction container (10) and the magnetic body piece (120) can be maintained even if the bottom of the induction container (10) is not flat or is partially deformed. That is, when the bottom of the induction container (10) is flat [see FIG. 3(b)], the entire bottom surface of the induction container (10) comes into contact with the upper surface of the magnetic body piece (120) while the degree of compression of the elastic body (130) by the induction container (10) is the same, but when the bottom is non-flat [see FIG. 3(c)], the elastic body (130) is less compressed only in the non-flat part of the induction container (10), and the entire bottom surface of the induction container (10) comes into contact with the upper surface of the magnetic body piece (120).

[0031] At this time, the elastic body is a magnetic body, and if it is in the shape of a coil spring and a cone, the contact area with the induction container (10) can be increased by pressing during the compression process.

[0032] Meanwhile, the elastic body can be modified to a shape other than a cone, such as a cylinder or a shape where the diameter gradually decreases from the top and bottom towards the center.

[0033] For example, when an elastic body in the shape of a conical coil spring is compressed by the weight of the induction container (10), it is deformed into a vortex shape, so the magnetic piece (120) is separated from the upper surface of the connecting part (110) by a height corresponding to the thickness of the spring.

[0034] In this way, the induction heating plate (100) according to the first embodiment of the present invention can cook food using electromagnetic waves generated from an induction cooker by placing an induction container (10) on top of a connecting part (110) having a mesh structure and fixing a plurality of small magnetic pieces (120) thereon. At this time, since the connecting part (110) is provided with a mesh structure and the size of the magnetic pieces (120) is small, the surface is prevented from warping and deforming due to the heat of the induction cooker.

[0035] Referring to FIGS. 4 and 5, the induction heating plate (200) according to the second embodiment of the present invention includes a connecting part (210), a magnetic piece (220), and a finishing part (230). Since the connecting part (210) and the magnetic piece (220) have the same structure and function as those of the preceding embodiment, a detailed description is omitted.

[0036] The finishing portion (230) is provided to wrap around the edge of the connecting portion (210) as shown in FIGS. 4 and 5, and is either an insulator or a conductor applied thereto.

[0037] At this time, the finishing part (230) is provided with a heat-resistant material, and in the case of a non-conductor, for example, synthetic resin, rubber, silicone, wood, or heat-treated wood is applied thereto, and in the case of a conductor, the finishing part (230) together with the connecting part (210) can be provided with a material such as stainless steel so that heat is transferred.

[0038] Furthermore, the finishing portion (230) is formed in an annular shape, has a handle (232) on its outer surface, and has a connecting groove (234) on its inner surface so that the edge of the connecting portion (210) is connected.

[0039] Furthermore, although the finishing portion (230) is exemplified as having the edge of the connecting portion (210) joined to the joining groove (234), it is not limited thereto, and if the finishing portion (230) is hard, the edge of the connecting portion (210) is not separated from the joining groove (234).

[0040] And the lower part of the magnetic piece (220) can be fixed by an elastic body (not shown in the drawing) that is fixed at the upper part of the connecting part (210) as in the previous embodiment.

[0041] In this way, the induction heating plate (200) according to the second embodiment of the present invention can cook food using electromagnetic waves generated from an induction cooker by placing an induction container (10) on top of a connecting part (210) having a mesh structure and fixing a plurality of small magnetic pieces (220) thereon. At this time, since the connecting part (210) is provided with a mesh structure and the size of the magnetic pieces (220) is small, the surface is prevented from warping and deforming due to the heat of the induction cooker. In addition, by providing a finishing part (230) provided at the edge of the connecting part (210), the magnetic pieces (220) do not come into contact even when the induction heating plates (200) are stacked, and since the finishing part (230) is detachable, cleaning is also easy.

[0042] Referring to FIG. 6, an induction heating plate (300) according to the third embodiment of the present invention includes a connecting part (310) and a magnetic piece (320).

[0043] As shown in FIG. 6, the connecting part (310) is provided as a heating plate, which is a conductor for transferring heat, so that heat from the induction cooker can be transferred to the induction container using electromagnetic waves generated from the induction cooker, and is provided in a linear structure to connect the opposing surfaces of the magnetic pieces (320).

[0044] At this time, the connecting part (310) can be joined at both ends by forming holes in the opposing surfaces of the magnetic body piece (320) with a metal wire, or can be joined to the opposing surfaces of the magnetic body piece (320) by welding or the like.

[0045] Furthermore, the connecting part (310) can be provided with a material such as stainless steel, for example, to prevent deformation caused by the heat of the induction cooker.

[0046] As shown in FIG. 5, the magnetic pieces (320) are arranged in a plurality, and both ends of the connecting part (310) are joined to the opposite surface, and holes are machined so that they can pass through the connecting part (310) like abacus beads, and are provided so that heat is conducted to the induction container while increasing the contact area with the induction container that contacts the top.

[0047] At this time, the magnetic body piece (320) is provided in a plate structure such as a circle or a polygon. And the magnetic body piece (320) can be perforated.

[0048] In this way, since the magnetic piece (320) is provided in a small size, it is possible to prevent bending or warping caused by the heat of the induction cooker, just like the connecting part (310).

[0049] In this way, the induction heating plate (300) according to the third embodiment of the present invention can cook food using electromagnetic waves generated from an induction cooker by placing an induction container on it while the ends of the connecting part (310), which is provided in a linear structure, are fixed to the opposing surfaces of a plurality of magnetic pieces (320) arranged at set positions. At this time, since the connecting part (310) is provided in a linear structure and the size of the magnetic pieces (320) is small, the surface is prevented from warping and deforming due to the heat of the induction cooker.

[0050] The configurations included in the various embodiments described above may also be implemented in various other possible modified combinations not exemplarily described above, provided that such combinations are not clearly excluded from one another in terms of implementation.
