[0039] Reference Figures 1 to 8As shown, a heating plate heat insulation structure of one embodiment of the present invention includes: a top cover, a bottom shell 100, a heating plate 200, and a heat insulation component 300.

[0040] Reference Figure 1 , Figure 2 and Figure 3 As shown, the bottom shell 100 has an upward-opening accommodating cavity. Both the heating plate 200 and the heat insulation component 300 are located within this cavity. The upper end of the heat insulation component 300 is connected to the heating plate 200, and the lower end is connected to the bottom shell 100, thus supporting the heating plate 200. A top cover is placed over the upper ends of the heating plate 200 and the bottom shell 100 to close the upper opening of the accommodating cavity. After the heating plate 200 is connected to an external power source, it generates a large amount of heat, which is transferred to the bottom of the cookware through radiant heat transfer, thereby heating the cookware.

[0041] Reference Figure 1 , Figure 2 and Figure 4 As shown, multiple heat insulation components 300 are arranged circumferentially around the heating plate 200 to achieve multi-point stable support for the heating plate 200. Specifically, the heat insulation component 300 includes a compression elastic element 320 and a heat insulation pad 310. The heat insulation pad 310 is made of heat insulation material and is connected to the heating plate 200. The upper and lower ends of the compression elastic element 320 are connected to the heat insulation pad 310 and the bottom shell 100, respectively, to support the heating plate 200 and create a heat dissipation space 110 between the lower end of the heating plate 200 and the bottom shell 100. With the help of an external fan, the heat emitted by the heating plate 200 can be effectively carried away by the air, thereby avoiding the problem of a large amount of heat being transferred to the bottom shell 100 due to large-area contact or contact between the heating plate 200 and the bottom shell 100.

[0042] Reference Figure 1 , Figure 4 and Figure 5 As shown, the heat insulation pad 310 is a heat insulation material component. The heating plate 200 is connected to the bottom shell 100 through the heat insulation pad 310 and the compression elastic element 320. The heat insulation pad 310 can effectively block the transfer of heat, that is, effectively block or reduce the heat transferred from the heating plate 200 to the bottom shell 100, which is beneficial to reduce the heat resistance requirements of the bottom shell 100, thereby reducing the manufacturing cost of the bottom shell 100.

[0043] Reference Figure 1 , Figure 5 and Figure 5As shown, specifically, the compression elastic element 320 can be a spring. While providing stable support for the heating plate 200, it can effectively reduce the heat absorption area of ​​the compression elastic element 320, thereby reducing the heat transferred from the compression elastic element 320 to the bottom shell 100. This helps to reduce the temperature of the bottom shell 100 when the heating plate 200 is operating, thereby reducing the requirements for the heat resistance of the bottom shell 100 and reducing the manufacturing cost of the bottom shell 100.

[0044] Reference Figure 1 , Figure 4 and Figure 5 As shown, specifically, the heat insulation pad 310 can be heat insulation rubber, polystyrene or phenolic resin, etc., which can effectively block the heat transferred from the heating plate 200 to the bottom shell 100, which helps to reduce the temperature of the bottom shell 100 when the heating plate 200 is operating, thereby reducing the requirements for the heat resistance of the bottom shell 100 and reducing the manufacturing cost of the bottom shell 100.

[0045] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the outer edge of the heating plate 200 is connected to a plurality of circumferentially arranged connecting ears 400, each connecting ear 400 being connected to at least one heat insulation member 300, and the heat insulation pad 310 being connected to the connecting ear 400. The connecting ears 400 and the heat insulation member 300 are arranged around the outer edge of the heating plate 200, which can reduce the obstruction of the connecting ears 400 and the heat insulation member 300 to the heat dissipation of the heating plate 200.

[0046] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the heating plate 200 has three circumferentially arranged connecting ears 400 connected to its outer edge. Correspondingly, the heating plate insulation structure includes three insulation components 300, that is, the connecting ears 400 and the insulation components 300 are connected one-to-one to achieve stable support for the heating plate 200, thereby avoiding the problem of the heating plate 200 tilting relative to the bottom shell 100.

[0047] It should be understood that in some other embodiments, the outer edge of the heating plate 200 is connected to three or more circumferentially arranged connecting ears 400, which, together with the connection between the heat insulation member 300 and the connecting ears 400, provide stable support for the heating plate 200.

[0048] It should be understood that in some other embodiments, each connecting lug 400 corresponds to two or more thermal insulation members 300 connected.

[0049] Reference Figure 4 , Figure 6 and Figure 7As shown, it can be understood that in this embodiment, the connecting ear 400 is provided with a through mounting hole 410, and the heat insulation pad 310 is inserted into the mounting hole 410. The outer peripheral surface of the heat insulation pad 310 abuts against the inner peripheral surface of the mounting hole 410, so that the heat insulation pad 310 is locked in the mounting hole 410, thereby realizing the positioning and detachable connection between the heat insulation pad 310 and the connecting ear 400.

[0050] Reference Figure 4 , Figure 6 and Figure 7 As shown, specifically, the lower end of the heat insulation pad 310 is connected to a limiting ring 314. When the heat insulation pad 310 is inserted into the mounting hole 410, the upper end of the limiting ring 314 abuts against the lower end of the connecting ear 400 at the outer edge of the mounting hole 410, so as to realize the support of the heat insulation pad 310 for the connecting ear 400.

[0051] Since the upper and lower ends of the compression elastic element 320 are connected to the heat insulation pad 310 and the bottom shell 100 respectively, the compression elastic element 320 can apply an upward supporting force to the heat insulation pad 310. Through the abutment of the limiting ring 314 with the connecting ear 400, the heat insulation component 300 supports the connecting ear 400, and can effectively prevent the heat insulation pad 310 from going upward through the mounting hole 410.

[0052] The lower surface of the limiting ring 314 is provided with a plurality of protrusions 315 arranged in a circumferential direction. The protrusions 315 are used to abut against the upper end of the compression elastic member 320, which can effectively reduce the contact area between the compression elastic member 320 and the limiting ring 314, effectively block or reduce the heat transferred from the heating plate 200 to the bottom shell 100, which is conducive to reducing the heat resistance requirements of the bottom shell 100, thereby reducing the manufacturing cost of the bottom shell 100.

[0053] Reference Figure 4 , Figure 6 and Figure 7 As shown, it is understood that in order to ensure that the compression elastic member 320 can maintain its connection with the bottom shell 100 and the heat insulation pad 310 to maintain the stability of the heat dissipation space 110, the heat insulation member 300 also includes a guide post 330.

[0054] Reference Figure 4 , Figure 6 and Figure 7As shown, the heat insulation pad 310 has a through hole 311 extending vertically. The inner diameter of the through hole 311 is larger than the outer diameter of the guide post 330. The two ends of the guide post 330 are arranged vertically. The lower end of the guide post 330 is fixedly connected to the bottom shell 100. The compression elastic element 320 is sleeved on the outer periphery of the guide post 330, and the upper end of the guide post 330 passes through the through hole 311. That is, the heat insulation component 300 can restrict the movement of the compression elastic element 320 along the horizontal plane through the guide post 330 and guide the expansion and contraction of the compression elastic element 320 so that the compression elastic element 320 can expand and contract in the vertical direction, thereby ensuring that the compression elastic element 320 can provide stable support for the heat insulation pad 310.

[0055] Reference Figure 4 , Figure 6 and Figure 7 As shown, specifically, the upper end of the guide post 330 passes through the through hole 311. Through the mutual cooperation between the outer peripheral surface of the guide post 330 and the inner peripheral surface of the through hole 311, the positioning of the heating plate 200 relative to the bottom shell 100 can be assisted, making the positioning and installation of the heating plate 200 simpler and more convenient.

[0056] Reference Figure 4 , Figure 6 and Figure 7 As shown, the inner diameter of the perforation 311 is larger than the outer diameter of the guide post 330. This facilitates the guide post 330 passing through the perforation 311, helping to install the heating plate 200 and the bottom shell 100, while avoiding problems caused by machining errors or component deformation due to heat.

[0057] Reference Figure 4 , Figure 6 and Figure 7 As shown, the heat insulation pad 310 has at least two snap-fit ​​teeth 312 arranged circumferentially around the through hole 311. The upper end of the snap-fit ​​teeth 312 has a hook portion 3121 that gradually narrows from bottom to top. The snap-fit ​​teeth 312 pass through the mounting hole 410 and abut against the inner circumferential surface of the mounting hole 410. The lower end of the hook portion 3121 abuts against the upper end of the connecting ear 400 at the outer edge of the mounting hole 410 to prevent the heat insulation pad 310 from falling out of the mounting hole 410.

[0058] Reference Figure 4 , Figure 6 and Figure 7 As shown, the heat insulation component 300, through the engagement of the snap-fit ​​teeth 312 and the limiting ring 314 with the connecting ear 400, can realize the snap-fit ​​and positioning of the heat insulation pad 310 and the connecting ear 400, so as to improve the connection accuracy and connection stability of the heat insulation pad 310 and the connecting ear 400.

[0059] Reference Figure 4 , Figure 6 and Figure 7As shown, it is understandable that in order to further improve the connection stability between the heat insulation pad 310 and the connecting ear 400 and reduce the loosening or shaking between the heat insulation pad 310 and the connecting ear 400, the upper end of the heat insulation pad 310 has a guide block 313 disposed between two snap-fit ​​teeth 312. The upper end of the guide block 313 has a guide portion 3131 that gradually narrows from bottom to top. The guide block 313 passes through the mounting hole 410 and abuts against the inner circumferential surface of the mounting hole 410. The guide block 313 and the snap-fit ​​teeth 312 are arranged at intervals.

[0060] Reference Figure 4 , Figure 6 and Figure 7 As shown, specifically, the heat insulation pad 310 is provided with two snap-fit ​​teeth 312 and two guide blocks 313. The central axis of the perforation 311 is located on the line connecting the two snap-fit ​​teeth 312, and the central axis of the perforation 311 is also located on the line connecting the two guide blocks 313. The line connecting the two guide blocks 313 is arranged at a right angle to the line connecting the two snap-fit ​​teeth 312.

[0061] When the heat insulation pad 310 is inserted into the mounting hole 410, the outer peripheral surfaces of the two guide blocks 313 and the two snap-fit ​​teeth 312 abut against the inner edge of the mounting hole 410, thereby improving the stability of the fit between the heat insulation pad 310 and the mounting hole 410 and helping to reduce the loosening or shaking between the heat insulation pad 310 and the connecting ear 400.

[0062] Reference Figure 4 , Figure 6 and Figure 7 As shown, during assembly, the user can align the heat insulation pad 310 with the mounting hole 410 and apply pressure to the heat insulation pad 310 through the mounting hole 410, so that the narrow end of the hook 3121 and the narrow end of the guide 3131 first pass through the mounting hole 410, and then the outer peripheral surface of the hook 3121 gradually abuts against the inner peripheral surface of the mounting hole 410 until the limiting ring 314 abuts against the connecting ear 400. At this time, the hook 3121 and the guide 3131 completely pass through the mounting hole 410, and the lower end of the hook 3121 can abut against the upper end of the connecting ear 400 on the outer edge of the mounting hole 410, so as to restrict the heat insulation pad 310 from falling out of the mounting hole 410, so that the connecting ear 400 is locked between the hook 3121 and the limiting ring 314, so as to realize the positioning and fixed connection between the heat insulation pad 310 and the connecting ear 400.

[0063] Reference Figure 4 , Figure 6 and Figure 7 As shown, when disassembly is required, the user can press the narrow end of the snap-fit ​​tooth 312 inward with their hand to separate the lower end of the hook 3121 from the upper end of the connecting ear 400 at the outer edge of the mounting hole 410. Then, the user can press the heat insulation pad 310 downward to make the heat insulation pad 310 exit the mounting hole 410, thereby achieving the separation of the heat insulation pad 310 and the connecting ear 400.

[0064] Reference Figure 4 , Figure 6 and Figure 7 As shown, the limiting ring 314 has a notch 316 in the area corresponding to the locking tooth 312 along the vertical direction. The heat insulation pad 310 can be injection molded by a mold. The notch 316 can be used for mold separation, thereby reducing the manufacturing cost of the heat insulation pad 310.

[0065] Reference Figure 4 , Figure 6 and Figure 7 As shown, it can be understood that the connecting ear 400 and the heating plate 200 are detachably connected. Specifically, the end of the connecting ear 400 away from the mounting hole 410 is provided with a first mounting hole 410, and the lower end of the outer edge of the heating plate 200 is provided with a second connecting hole. The heating plate heat insulation structure also includes a first connector, which passes through the first connecting hole 430 and the second connecting hole to fix the connecting ear 400 and the heating plate 200.

[0066] Reference Figure 4 , Figure 6 and Figure 7 As shown, specifically, the first connector can be a screw, the first connecting hole 430 is a through hole, and the second connecting hole is a screw hole. After the first connector passes through the first connecting hole 430, it can be threadedly connected to the second connecting hole. Through the tightness of the first connector, a stable connection between the connecting ear 400 and the heating plate 200 is achieved.

[0067] Reference Figure 4 , Figure 5 and Figure 8 As shown, it is understood that in order to enhance the strength and bending resistance of the connecting ear 400, the connecting ear 400 has at least two reinforcing ribs 420 arranged circumferentially along the heating plate 200, and the reinforcing ribs 420 abut against the outer peripheral surface of the heating plate 200.

[0068] Reference Figure 4 , Figure 5 and Figure 8 As shown, the connecting ear 400 abuts against the outer peripheral surface of the heating plate 200 through two reinforcing ribs 420, which can effectively resist the bending of the connecting ear 400 relative to the outer peripheral surface of the heating plate 200, thereby improving the connection stability between the connecting ear 400 and the heating plate 200. In addition, the abutment between the two reinforcing ribs 420 and the outer peripheral surface of the heating plate 200 can quickly position the installation position of the connecting ear 400 and the heating plate 200, thereby improving the connection efficiency between the connecting ear 400 and the heating plate 200.

[0069] Reference Figure 1 , Figure 2 and Figure 3As shown in the figure, this utility model provides a heating appliance, which includes a heating plate heat insulation structure as described in any of the above embodiments. Multiple heat insulation components 300 are arranged circumferentially around the heating plate 200 to provide stable support for the heating plate 200. Specifically, each heat insulation component 300 includes a compression elastic element 320 and a heat insulation pad 310. The heat insulation pad 310 is connected to the heating plate 200. The upper and lower ends of the compression elastic element 320 are respectively connected to the heat insulation pad 310 and the bottom shell 100 to support the heating plate 200 and to ensure that the lower end of the heating plate 200 is separated from the bottom shell 100. A heat dissipation space 110 is constructed, which, together with an external fan, can effectively remove the heat emitted by the heating plate 200 through air. This avoids the problem of a large amount of heat being transferred to the bottom shell 100 due to the heating plate 200 being in close contact with the bottom shell 100 over a large area. In addition, the heat insulation pad 310 is made of heat insulation material. The heating plate 200 is connected to the bottom shell 100 through the heat insulation pad 310 and the compression elastic element 320. The heat insulation pad 310 can effectively block the transfer of heat, that is, effectively block or reduce the heat transferred from the heating plate 200 to the bottom shell 100. This helps to reduce the heat resistance requirements of the bottom shell 100, thereby reducing the manufacturing cost of the bottom shell 100.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
