[0029] Reference Figure 1-6 The figure shows a preferred embodiment of the present invention.

[0030] The cooking heater with multiplied electric power provided in this embodiment can be a series of heaters such as a baking tray or a hot pot stove that can heat and cook food, and is not limited to a specific heater.

[0031] A cooking heater for multiplying electric power includes a plate body 100 and a controller. The plate body 100 has an inner cavity 103. A sintered heating plate 300 is provided at the bottom of the inner cavity 103. The top of the heating plate 300 is exposed at the bottom of the inner cavity 103. Two heating bodies 305 with equal power for electrically heating are provided in the heating plate 300. The two heating bodies 305 are arranged independently. The heating plate 300 is connected to the plate body 100 to form an integrated structure. The controller controls the heating body 305 to be in a powered-on state or a powered-off state.

[0032] The controller serves as an overall control platform, which controls the operation of the entire cooking heater. It includes a circuit board and a knob, etc., and control is achieved by turning the knob, or by buttons, or by a touch screen, etc.

[0033] When food ingredients need to be cooked, the food ingredients can be directly placed in the inner cavity 103, which can be used as a baking tray or a hot pot tray. The heating body 305 is powered on to generate heat, and the heat is directly transferred to the food ingredients in the inner cavity 103 to achieve cooking of the food ingredients.

[0034] The cooking heater for doubling electric power provided above arranges two heating bodies 305 of equal power. Thus, during the cooking heating process, a controller can be used to select to start one or two heating bodies 305, or to start them at different times, so as to achieve heating with doubled or doubled electric power. Secondly, the heating plate 300 is connected to the disc body 100 to form an integrated structure, which facilitates the heat of the heating plate 300 to be transferred to the inner cavity 103 of the disc body 100, thereby achieving high-efficiency heat transfer and having the advantage of low energy consumption.

[0035] In this embodiment, the heating body 305 is a heating wire, which is arranged in a spiral shape on the heating plate 300, and two heating bodies 305 are arranged in a spiral shape with an interval therebetween, so that the heating body 305 can be evenly heated along the plane direction of the entire heating plate 300.

[0036] Specifically, the heating body 305 is arranged in a spiral from the middle of the heating plate 300 toward the periphery of the heating plate 300 , so that the heating body 305 is easily arranged in a spiral and spreads throughout the plane direction of the entire heating plate 300 as much as possible.

[0037] In this embodiment, the interior of the heating plate 300 has two insulating titanium alloy ceramic layers 304 sintered therein, and the heating body 305 is sintered between the two titanium alloy ceramic layers 304 and sintered as a whole with the two titanium alloy ceramic layers 304. In this way, the heat energy storage of the heating body 305 is facilitated, and more efficient heat transfer can be achieved, so as to achieve the effects of high-efficiency and rapid heating, and achieve a high degree of energy saving and emission reduction.

[0038] The insulation and energy storage properties of the titanium alloy ceramic layer 304 are very advantageous, and can better achieve more efficient heat transfer, high-efficiency heat generation, and rapid heat generation, thereby achieving a high degree of energy saving and emission reduction.

[0039] In this embodiment, the heating plate 300 includes a top plate 301 and a bottom plate 303, and the top plate 301 and the bottom plate 303 are made of metal materials. Two layers of titanium alloy ceramic layers 304 are sintered and clamped between the top plate 301 and the bottom plate 303, and the top plate 301, the two layers of titanium alloy ceramic layers 304, the two heating bodies 305 and the bottom plate 303 are sintered to form an integrated structure; the top plate 301 is connected to the disk body 100 to form an integrated structure, and the top plate 301 is exposed at the bottom of the inner cavity 103.

[0040] In actual manufacturing, the titanium alloy ceramic layer 304 is first sintered at high temperature directly on the bottom plate 303, and then the heating body 305 is arranged on the titanium alloy ceramic layer 304, and the titanium alloy ceramic layer 304 is sintered at high temperature on the heating body 305, so that the heating body 305 is built into the titanium alloy ceramic layer 304, and finally, the top plate 301 is arranged on the titanium alloy ceramic layer 304, and high-temperature sintering is performed to combine the top plate 301 with the titanium alloy ceramic layer 304 into one, and the entire heating plate 300 is combined into an integrated structure.

[0041] The entire heating plate 300 forms an integrated structure, which is convenient for the manufacture of the heating plate 300 and the assembly connection between the heating plate 300 and the disk body 100, and can make the heating plate 300 and the disk body 100 combined into an integrated structure, so that the heat generated by the heating plate 300 is transferred to the inner cavity 103 of the disk body 100.

[0042] In this embodiment, the inner wall of the disk body 100 is provided with an upwardly arranged annular step, and a connecting ring 302 extends outward from the outer periphery of the top plate 301. The connecting ring 302 overlaps the annular step and abuts against the inner wall of the disk body 100. The connecting ring 302 and the disk body 100 are welded and fixed to form an integrated structure.

[0043] The top plate 301 and the dish body 100 are overlapped up and down, which is convenient for the direct connection between the top plate 301 and the dish body 100, and the connection structure is more stable. By welding, the heating plate 300 and the dish body 100 can be combined together to form a complete integrated structure.

[0044] The upper and lower overlaps of the connecting ring 302 and the annular step facilitate the matching installation between the heating plate 300 and the disk body 100, and facilitate the welding operation between the connecting ring 302 and the disk body 100.

[0045] In this embodiment, the bottom of the disk body 100 extends downward to form an annular wall 104, and the bottom of the annular wall 104 is covered with a disk bottom plate 105. The disk body 100, the annular wall 104 and the bottom plate 303 are formed as one piece; the annular wall 104 and the disk bottom plate 105 enclose a bottom cavity, and the heating plate 300 is embedded in the bottom cavity; the top plate 301 covers the top of the bottom cavity, and the top cavity is arranged in a closed manner.

[0046] In this way, the heating plate 300 can be effectively accommodated, and when the heating plate 300 is connected to the tray body 100, the bottom cavity forms a closed space, which can realize efficient heat transfer of the heating plate 300.

[0047] In this embodiment, there is a bottom insulation gap 106 between the heating plate 300 and the disk bottom plate 105, and there is a peripheral insulation gap 107 between the outer periphery of the heating plate 300 and the annular wall 104. The peripheral insulation gap 107 is arranged around the circumference of the heating plate 300 and is connected to the bottom insulation gap 106.

[0048] In this way, the heat of the heating plate 300 will not be transferred to the bottom plate 105 of the dish, which can play a heat insulation effect. The heat of the heating plate 300 is efficiently transferred to the top plate 301, and then transferred to the inner cavity 103 through the top plate 301, so as to achieve efficient cooking of the ingredients.

[0049] In this embodiment, the connecting ring 302 has an overlapping section 3021 overlapping the annular step and a suspended section 3022 exposed above the peripheral insulation spacer 107; a support plate 500 made of metal material is provided in the bottom insulation spacer 106, and the support plate 500 is arched upward to form a plurality of arched portions 501, and the arched portions 501 surround a lower groove 502 with a bottom opening.

[0050] A plurality of arched portions 501 are arranged at intervals, and a flat portion is provided on the top of the arched portion 501, and the flat portion is fixedly connected to the bottom plate 303 as a whole, and a through hole 503 is provided in the flat portion that passes through the flat portion from top to bottom; the lower groove 502 is filled with an insulating energy storage titanium alloy ceramic block 504, and the titanium alloy ceramic block 504 is abutted against the bottom plate 303 through the through hole 503; the bottom of the support plate 500 is arranged at intervals with the disk bottom plate 105.

[0051] The periphery of the support plate 500 is extended to form a peripheral plate 509, which is placed in the peripheral insulation space 107 and arranged around the periphery of the peripheral insulation space 107. The peripheral plate 509 and the support plate 500 are arranged in a bent manner, and the peripheral plate 509 is arranged in a peripheral interval with the annular wall 104 and the heating plate 300; the top of the peripheral plate 509 is docked and fixed with the suspension section 3022, and along the direction from top to bottom of the peripheral plate 509, the peripheral plate 509 is arranged in a multi-section curved shape.

[0052] First, the support plate 500 and the peripheral plate 509 can support the heating body 305, strengthen the structural strength of the heating plate 300, avoid deformation of the heating plate 300, and form a stable integrated structure between the heating plate 300 and the plate body 100. 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;

[0053] Secondly, the peripheral plate 509 abuts against the suspension section 3022, and the support plate 500 forms a plurality of arched portions 501 abutting against the bottom plate 303, which can achieve more efficient heat transfer from the heating body 305 to the top plate 301 on the basis of providing structural support;

[0054] Furthermore, 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, and the titanium alloy ceramic block 504 abuts against the bottom plate 303 through the through hole 503, so that the stored heat can be transferred to the heating plate 300 more quickly;

[0055] 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 .

[0056] In this embodiment, the middle portion of the support plate 500 is arched toward the bottom plate 303 to form a convex surface arrangement; the bottom of the support plate 500 is covered with an integrated thermal insulation layer 506, and the thermal insulation layer 506 covers the bottom of the titanium alloy ceramic block 504; the thermal insulation layer 506 extends to the outer wall of the peripheral plate 509 and covers the outer wall of the peripheral plate 509; the periphery of the support plate 500 is connected to a plurality of spaced thermal insulation pads 505, and the thermal insulation pads 505 are docked on the disk bottom plate 105, and the plurality of thermal insulation pads 505 support the support plate 500 and the heating plate 300 from bottom to top.

[0057] The support plate 500, the peripheral plate 509 and the heating plate 300 enclose a sealed energy storage space; the support plate 500, the peripheral plate 509, the annular wall 104 and the bottom plate 105 of the dish enclose a heat-insulating space, and the bottom plate 105 of the dish has air holes connected to the heat-insulating space. In this way, the heat of the heating plate 300 can be quickly and efficiently transferred to the top plate 301, and then transferred to the inner cavity 103 of the dish body 100. By forming an energy storage space, the heat is limited from being transferred downward to the bottom plate 105 of the dish. The bottom plate 105 of the dish is provided with air holes, which can enhance the air flow in the heat-insulating space to achieve heat dissipation of the bottom plate 105 of the dish.

[0058] By arranging the thermal insulation layer 506, the heat transfer to the bottom plate 105 of the disk can be limited to maintain a better thermal insulation effect; by setting the thermal insulation pad 505, the bottom of the support plate 500 can be supported, the structural strength of the support plate 500 can be maintained, and the structural strength of the heating body 305 is further enhanced.

[0059] In this embodiment, two swinging support legs 101 and a control seat 400 are provided at the bottom of the tray bottom. The two support legs 101 and the control seat 400 are arranged around the circumference of the tray body 100 at intervals, thereby forming a three-position support for the tray body 100, so that the tray body 100 can be arranged in a suspended state.

[0060] Alternatively, the support leg 101 can be passively moved to the bottom of the disc body 100 by swinging, so that the support leg 101 is in a storage state, and the control seat 400 can be directly removed from the disc body 100. In this way, the disc body 100 can also be directly placed on a support, or can be stored.

[0061] 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.

[0062] When the top plate 301 and the titanium alloy ceramic layer 304 are sintered and connected as one, the cone 306 is embedded in the titanium alloy ceramic layer 304 and has a gap with the heating body 305. The titanium alloy ceramic layer 304 fills the cone cavity and covers the entire cone 306. In this way, the top plate 301 and the titanium alloy ceramic layer 304 can be combined into a more stable integrated structure, and the contact and abutment area between the top plate 301 and the titanium alloy ceramic layer 304 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.
