[0037] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] like Figures 1-5 As shown, the cooking appliance of this utility model embodiment includes a pot body 1, a heating element 2, and a heat insulation component 3.

At least a portion of the first heat insulation component 31, the second heat insulation component 32, and the heat insulation cover 33 are arranged sequentially from top to bottom at intervals. The first heat insulation component 31 is adjacent to the heating element 2.

[0039] The cooking appliance of this utility model embodiment reduces the heat transferred from the heating element 2 to the table when heating the pot body 1 by setting a first heat insulation member 31, thereby improving the heating efficiency of the heating element 2 to the pot body 1. Moreover, if the heating element 2 reaches an extremely high temperature and causes the metal (e.g., aluminum) on the heating element 2 to melt, the first heat insulation member 31 can catch the molten metal to prevent it from flowing out. By setting a second heat insulation member 32 and arranging it at intervals from the first heat insulation member 31, the second heat insulation member 32 can reflect heat, further reducing the heat transferred from the heating element 2 to the table. A heat insulation cover 33 is set at intervals below the second heat insulation member 32 to further insulate the heat, prevent the table temperature from getting too high, and improve the safety of using the cooking appliance.

[0040] Specifically, the heating element 2 is bent and coiled around the bottom surface of the pot body 1 to improve the heating efficiency of the pot body 1. The vertical distance between the first heat insulation element 31 and the second heat insulation element 32 is 2mm-7mm, preferably 5mm. The vertical distance between at least a portion of the second heat insulation element 32 and the heat insulation cover 33 is 2mm-7mm, preferably 5mm. Through the above arrangement, the heat insulation assembly 3 can better insulate the heat generated by the heating element 2, thereby improving safety.

[0041] In some embodiments, the cooking appliance of this utility model may be an electric hot pot, etc. The heat insulation component 3 can provide multi-layer heat insulation for the heat generated by the heating element 2 to prevent the table surface temperature from getting too high and ensure the safety of the user.

[0042] In some embodiments, when the cooking appliance is subjected to high temperature resistance testing before mass production and market launch, the temperature control device of the cooking appliance is turned off, so that the heating element 2 continues to heat, in order to test the effect of the cooking appliance on the table temperature. The cooking appliance of this application can significantly reduce the problem of excessive table temperature rise during the testing phase.

[0045] Optionally, such as Figure 2 and Figure 3As shown, the cooking appliance also includes a first support member 4, which is disposed between the first heat insulation member 31 and the second heat insulation member 32. Specifically, the first support member 4 separates the first heat insulation member 31 and the second heat insulation member 32, which is simple to operate and creates an air layer between the first heat insulation member 31 and the second heat insulation member 32, reducing the transfer of heat from the first heat insulation member 31 to the second heat insulation member 32.

[0046] Optionally, such as Figure 2 and Figure 3 As shown, the cooking appliance also includes a second support 5, which is disposed between at least a portion of the second heat insulation member 32 and the heat insulation cover 33. Specifically, the second support 5 separates the second heat insulation member 32 and the heat insulation cover 33, which is simple to operate and also forms an air layer between the second heat insulation member 32 and the heat insulation cover 33, reducing heat transfer.

[0047] Optionally, such as Figure 2 and Figure 4 As shown, the bottom surface of the pot body 1 is also provided with a protruding post 13, which passes through the first heat insulation member 31 and the second heat insulation member 32.

The protrusion 13 has a threaded hole 131. The fastener passes through the third through hole 331 and is threaded into the threaded hole 131 to connect the heat insulation cover 33, the second heat insulation component 32, and the first heat insulation component 31. The connection method is simple and firm.

[0049] Optionally, such as Figure 2 As shown, both the first support member 4 and the second support member 5 are sleeved on the protruding post 13. Specifically, the first support member 4 has a first through hole 41, and the second support member 5 has a second through hole 51. The first support member 4 and the second support member 5 are sleeved on the protruding post 13 through the through holes, making the installation of the first support member 4 and the second support member 5 simple and firm.

[0050] Optionally, such as Figure 3 As shown, there are at least two protruding pillars 13, which are arranged at intervals. There are at least two first support members 4 and at least two second support members 5. The at least two protruding pillars 13, the at least two first support members 4 and the at least two second support members 5 correspond one-to-one.

[0051] Specifically, at least two protrusions 13 are evenly spaced around the bottom surface of the pot body 1 in the circumferential direction. There are at least two first perforations 311, at least two second perforations 321, and at least two third perforations 331. The at least two first perforations 311, at least two second perforations 321, at least two third perforations 331, and at least two protrusions 13 correspond one-to-one. This can further limit the position of the first heat insulation component 31, the second heat insulation component 32, and the heat insulation cover 33, so that the first heat insulation component 31, the second heat insulation component 32, and the heat insulation cover 33 are installed firmly and are not easy to rotate.

[0052] The arrangement of at least two first support members 4 and at least two second support members 5 ensures that the distance between the first heat insulation member 31 and the second heat insulation member 32, as well as the distance between the second heat insulation member 32 and the heat insulation cover 33, can be kept consistent, thus ensuring the heat insulation effect of the first heat insulation member 31, the second heat insulation member 32, and the heat insulation cover 33.

[0053] Optionally, such as Figure 3 As shown, the bottom surface of the pot body 1 has a mating part 14, the first heat insulation member 31 has a first slot 312, and the second heat insulation member 32 has a second slot 322. The first slot 312 and the second slot 322 both mate with the mating part 14, so that the mating part 14 can limit the first heat insulation member 31 and the second heat insulation member 32, so that the first heat insulation member 31 and the second heat insulation member 32 are installed securely.

[0054] Optionally, such as Figure 1 As shown, the cross-sectional area of ​​the first heat insulation component 31 is the same as that of the second heat insulation component 32, and the central axis of the first heat insulation component 31 is collinear with the central axis of the second heat insulation component 32. This ensures the heat insulation effect of the first heat insulation component 31 and the second heat insulation component 32, and makes the first heat insulation component 31 and the second heat insulation component 32 easy to manufacture and simple to install.

[0055] Optionally, the first heat insulation element 31 is a stainless steel sheet, preferably a mirror-finished stainless steel sheet, so that the first heat insulation element 31 can reflect the heat generated by the heating element 2, and the stainless steel sheet has the characteristic of high temperature resistance, which can reduce the heat transferred to the second heat insulation element 32.

[0056] Optionally, the second heat insulation element 32 is an aluminum sheet, which improves the heat absorption and heat reflection effect of the second heat insulation element 32 and reduces the heat transferred to the heat insulation cover 33.

[0057] Optionally, the heat insulation cover 33 is a galvanized cover. Galvanized covers have low material costs and can effectively save on manufacturing costs.

[0058] Optionally, such as Figure 5As shown, the heat insulation cover 33 includes a bottom wall 332 and a peripheral wall 333 connected to the outer periphery of the bottom wall 332. The bottom wall 332 and the second heat insulation member 32 are arranged at intervals in the vertical direction, and the top of the peripheral wall 333 is engaged with the bottom surface of the pot body 1.

[0059] Specifically, the third perforation 331 is provided on the bottom wall 332 and is evenly spaced around the bottom wall 332 in a circumferential manner. The cross-sectional area of ​​the first heat insulation element 31 and the cross-sectional area of ​​the second heat insulation element 32 are both smaller than the cross-sectional area enclosed by the peripheral wall 333. The first heat insulation element 31 and the second heat insulation element 32 are provided inside the heat insulation cover 33, which can protect the first heat insulation element 31 and the second heat insulation element 32, and can further isolate heat to prevent the tabletop temperature from being too high.
