[0045] The above-mentioned method for preparing a cooking heater based on titanium alloy ceramic coating forms a bottom insulating layer 3042 and a top insulating layer 3041 between the top plate 301 and the bottom plate 303 by sintering titanium alloy ceramics, and a heating body 305 is arranged between the bottom insulating layer 3042 and the top insulating layer 3041. The top plate 301, the top insulating layer 3041, the heating body 305, the bottom insulating layer 3042 and the bottom plate 303 are combined to form a heating plate 300 with an integrated structure. The titanium alloy ceramic has a better energy storage advantage, which is convenient for the heat transfer of the heating body 305; secondly, the heating plate 300 is connected to the dish body 100 to form an integrated structure, which is convenient for the heat of the heating plate 300 to be transferred to the inner cavity 103 of the dish body 100, thereby achieving high-efficiency heat transfer and having the advantages of low energy consumption.

[0046] In this embodiment, in the preparation step 1), the titanium alloy ceramic is covered on the bottom plate 303, and the titanium alloy ceramic is heated to a set temperature so that the titanium alloy ceramic and the bottom plate 303 are sintered and fused into one. After the titanium alloy ceramic is cooled, a bottom insulating layer 3042 integrated with the bottom plate 303 is formed.

[0047] The titanium alloy ceramic is heated at a high temperature, generally about 800° C., so that the titanium alloy ceramic can be sintered and fused to the bottom plate 303 , and the two can be integrated.

[0049] In this embodiment, in the preparation step 3), the titanium alloy ceramic is covered on the bottom insulating layer 3042 and covers the heating body 305; the titanium alloy ceramic is heated to a set temperature so that the titanium alloy ceramic and the bottom insulating layer 3042 are sintered and fused into one. After the titanium alloy ceramic is cooled, a top insulating layer 3041 combined with the bottom insulating layer 3042 is formed.

[0050] The titanium alloy ceramic is heated at a high temperature, generally about 800° C., so that the titanium alloy ceramic can be sintered and fused to the bottom insulating layer 3042 , and the heating body 305 is covered to form a top insulating layer 3041 , and the top insulating layer 3041 and the bottom insulating layer 3042 are combined into one.

[0052] In this embodiment, in the preparation step 5), the inner wall of the disk body 100 is provided with an upwardly arranged annular step, and a connecting ring 302 is extended outward from the outer periphery of the top plate 301; when the heating plate 300 is placed at the bottom of the inner cavity 103, the connecting ring 302 overlaps the annular step and abuts against the inner wall of the disk body 100, and the connecting ring 302 is welded and fixed to the disk body 100 so that the heating plate 300 and the disk body 100 form an integral structure; the top plate 301 covers the top of the recessed cavity to seal the recessed cavity.

[0053] By arranging the annular step, the connection ring 302 of the top plate 301 is conveniently overlapped with the annular step, so that the heating plate 300 and the disk body 100 can be installed and matched, and the connection ring 302 and the disk body 100 can be conveniently welded and fixed to form a whole. The heating plate 300 directly abuts against the annular step and the inner side wall of the disk body 100, which greatly improves the heat transfer efficiency.

[0054] In addition, the top plate 301 covers the top of the recessed cavity, so that the recessed cavity forms a sealed space, which is beneficial for the heating plate 300 to transfer heat to the inner cavity 103 of the disk body 100, thereby improving the heat transfer efficiency.

[0055] In this embodiment, in the preparation step 5), the bottom of the disk body 100 has a concave cup 104 extending downward, the disk body 100 and the concave cup 104 are integrally formed, and the concave cup 104 encloses the above-mentioned recessed cavity; the heating plate 300 is arranged at an interval with the inner side wall of the recessed cavity to form an insulating interval, and the insulating interval includes a bottom insulating interval 106 located below the bottom plate 303 and a peripheral insulating interval 107 located on the periphery of the heating plate 300, and the peripheral insulating interval 107 is connected to the bottom insulating interval 106.

[0056] During the manufacturing process, the disc body 100 and the concave cup 104 can be directly formed by forging and the like. When the heating plate 300 is placed at the bottom of the inner cavity 103, the heating plate 300 forms a bottom insulation gap 106 and a peripheral insulation gap 107 in the recessed cavity to prevent heat from being directly transferred to the concave cup 104, thereby playing a role of heat insulation and allowing the heat of the heating plate 300 to be transferred to the inner cavity 103 of the disc body 100, thereby achieving efficient heat transfer.

[0057] In this embodiment, in the preparation step 5), the connecting ring 302 has an overlapping section 3021 overlapped on the annular step and a hanging section 3022 exposed above the peripheral heat insulation spacer 107; a heat insulation board 500 made of metal is provided in the heat dissipation spacer, the top of the heat insulation board 500 is docked on the hanging section 3022, and the bottom of the heat insulation board 500 is located below the bottom plate 303;

[0058] The insulation plate 500 divides the heat dissipation interval into an energy storage space and an insulation space. The energy storage space is located between the heating plate 300 and the insulation plate 500, and the insulation space is located between the insulation plate 500 and the concave cup 104. The energy storage space and the insulation space are separated. The insulation plate 500 is arched upward and abuts against the bottom plate 303. The bottom of the insulation plate 500 is covered with an insulation layer 506, and the insulation layer 506 is located in the insulation space.

[0059] Firstly, the heat insulating plate 500 can support the heating body 305 , thereby enhancing the structural strength of the heating plate 300 and preventing the heating plate 300 from deforming, thereby forming a stable integrated structure between the heating plate 300 and the disk body 100 .

[0060] Secondly, the heat insulation board 500 is in contact with the suspension section 3022, and the heat insulation board 500 is arched upward and in contact with the bottom plate 303, which can achieve more efficient transfer of heat from the heating body 305 to the top plate 301 on the basis of providing structural support;

[0061] Furthermore, the heat insulation board 500 divides the heat dissipation interval into an energy storage space and a heat insulation space, and can further divide the heat insulation interval to achieve a better heat insulation effect and ensure that more heat is transferred to the top plate 301 to achieve better heat transfer efficiency.

[0062] In addition, the bottom of the insulation board 500 is covered with an insulation layer 506. The insulation layer 506 is located in the insulation space, which can form a secondary insulation effect and greatly improve the insulation effect.

[0063] In this embodiment, the heat insulation plate 500 includes a support plate located in the bottom heat insulation interval 106 and a peripheral plate 509 formed by extending from the periphery of the support plate. The support plate and the peripheral plate 509 are integrally formed and arranged in a bent manner. The support plate and the peripheral plate 509 integrally divide the heat dissipation interval into an energy storage space and a heat insulation space.

[0064] The support plate is arched upward to form a plurality of arched portions 501, which surround a lower groove 502 with an opening at the bottom. The plurality of arched portions 501 are arranged at intervals, and a flat portion is provided on the top of the arched portion 501, which is fixedly connected to the bottom plate 303 as a whole, and a through hole 503 is provided in the flat portion that runs through the flat portion from top to bottom; the lower groove 502 is filled with a titanium alloy ceramic block 504 for insulation and energy storage, and the titanium alloy ceramic block 504 is in contact with the bottom plate 303 through the through hole 503;

[0065] The peripheral plate 509 is placed in the peripheral insulation space 107 and arranged around the circumference of the peripheral insulation space 107. The top of the peripheral plate 509 is docked and fixed to the suspension section 3022, and along the direction from top to bottom of the peripheral plate 509, the peripheral plate 509 is arranged in multiple sections of curved shapes.

[0066] First, the peripheral plate 509 is arranged in a curved shape, which further enhances the structural strength of the peripheral plate 509 and provides a more stable support.

[0067] Secondly, by arranging the arched portion 501 and filling the titanium alloy ceramic block 504 in the lower groove 502, it can play an energy storage role, and by providing the through hole 503, it is convenient to weld the flat portion and the bottom plate 303 into one body. The titanium alloy ceramic block 504 abuts against the bottom plate 303 through the through hole 503, and the stored heat can be transferred to the heating plate 300 more quickly;

[0068] In addition, the heating plate 300 is supported at multiple positions by the plurality of arched portions 501 , thereby greatly enhancing the structural strength of the heating plate 300 .

The plurality of thermal insulation pads 505 support the support plate and the heating plate 300 from bottom to top, and the bottom of the concave cup 104 has air holes connected to the thermal insulation space.

[0071] By arranging the insulation layer 506, the heat transfer to the bottom of the concave cup 104 can be limited to maintain a better insulation effect; by setting the insulation pad 505, the bottom of the support plate can be supported, the structural strength of the support plate can be maintained, and the structural strength of the heating body 305 is further enhanced.

[0072] In this embodiment, two swinging support legs 101 and a control seat 400 are provided at the bottom of the concave cup 104. The two support legs 101 and the control seat 400 are arranged around the circumference of the disk body 100 at intervals, thereby forming a three-position support for the disk body 100, so that the disk body 100 can be arranged in a suspended state.

In this way, the disc body 100 can also be directly placed on a support, or can be stored.

[0074] In this embodiment, a cone cylinder 306 is provided at the bottom of the top plate 301. The cone cylinder 306 is integrally formed with the top plate 301. The interior of the cone cylinder 306 has a cone cavity that passes through the cone cylinder 306 from top to bottom. The diameter of the cone cavity gradually decreases along the cone cylinder 306 from top to bottom. A plurality of side holes 307 are provided in the cone cylinder 306, and the side holes 307 pass through the cone cylinder 306.

[0075] When the top plate 301 and the top insulating layer 3041 are sintered and connected as one, the cone 306 is embedded in the top insulating layer 3041 and has a gap with the heating body 305. The top insulating layer 3041 fills the cone cavity and covers the entire cone 306. In this way, the top plate 301 and the top insulating layer 3041 can be combined into a more stable integrated structure, and the contact area between the top plate 301 and the top insulating layer 3041 is increased. The heat emitted by the heating body 305 can be more efficiently transferred to the top plate 301, thereby achieving more efficient heat transfer.
