Wherein, the upper end of the shell 21 is provided with a pressure bearing ring 30, the pressure bearing ring 30 is an annular structure extending along the circumference of the shell 21, the upper end of the inner pot 22 is arranged on the pressure bearing ring 30, and the outer edge of the pressure bearing ring 30 is provided with a second buckling part 31 capable of buckling with the first buckling part 11.

[0043] By using the cooking utensil provided by the embodiment, after pressing the inner pot 22, the inner pot 22 transmits the pressure to the pressure bearing ring 30, and the upper end of the shell 21 supports the pressure bearing ring 30, so that the inner pot 22 does not need to be supported by the heat preservation cover, thereby reducing the cost of the cooking utensil. Moreover, since the pressure bearing ring 30 is an annular structure extending along the circumference of the shell 21, when the pressure bearing ring 30 is used for pressure bearing, the stress of the pressure bearing ring 30 is more uniform, which can further improve the pressure bearing strength of the pressure bearing ring 30, so that the support for the inner pot 22 is more stable.

[0044] It should be noted that since the upper end of the inner pot 22 can be arranged on the pressure bearing ring 30, the pressure bearing strength is improved, and the top pressure bearing can be realized by using the pressure bearing ring 30, so that the structural strength is improved, and the heat preservation cover is cancelled, thereby reducing the cost.

[0045] It should be noted that the upper end of the inner pot 22 is arranged on the pressure bearing ring 30, including that the upper end of the inner pot 22 is directly arranged on the pressure bearing ring 30, or the upper end of the inner pot 22 is indirectly arranged on the pressure bearing ring 30 through other components (for example, a support plate).

[0046] In the embodiment, the pressure bearing ring 30 is an annular structure, including the following two structures: the first is that the pressure bearing ring 30 is a circular ring structure, that is, the cross-sectional shape of the pressure bearing ring 30 is circular; the second is that the pressure bearing ring 30 is a polygonal ring structure, that is, the cross-sectional shape of the pressure bearing ring 30 is polygonal, for example, rectangular. That is, as long as the inner pot 22 can be supported by the pressure bearing ring 30.

[0047] The present application provides three embodiments according to the specific structure of the pressure bearing ring 30, which are embodiment one, embodiment two and embodiment three described below.

A second fastening part 31 is disposed on the outer edge of the pressure plate 32, and the upper end of the inner pot 22 is disposed on the pressure plate 32. The pressure plate 32 is disposed on the upper end of the shell 21. The pressure plate 32 has the advantages of simple structure and low cost, which can further reduce the cost of the cooking appliance.

[0049] It should be noted that the pressure plate 32 is provided at the upper end of the housing 21, including: the pressure plate 32 is directly erected at the upper end of the housing 21, or the pressure plate 32 is indirectly erected at the upper end of the housing 21 through other components (such as the second support ring mentioned below).

[0050] In this embodiment, the pressure plate 32 is arranged in a horizontal direction, which makes it easy to place the pressure plate 32 on the upper end of the shell 21 and also makes it easy to place the inner pot 22 on the upper end of the pressure plate 32.

[0051] In this embodiment, the inner edge of the pressure plate 32 is a cut-off structure, making the structure of the pressure plate 32 simpler and further reducing costs.

[0068] AsFigure 2 and Figure 5 As shown, the support plate 40 also includes a limiting cylinder 42, which is a cylindrical structure extending circumferentially along the housing 21. The upper end of the limiting cylinder 42 is connected to the inner edge of the first support ring 41. The limiting cylinder 42 extends downward into the housing 21 and is movably connected to the housing 21. The inner wall of the housing 21 has a relief groove 211 corresponding to the limiting cylinder 42. After the pressure ring 30 begins to bear pressure, the pressure ring 30 tends to flip its inner edge downward under force, which in turn causes the lower end of the limiting cylinder 42 to tend to flip outward. At this time, the relief groove 211 on the inner wall of the housing 21 can be used to avoid interference between the limiting cylinder 42 and the housing 21.

[0069] The lower end of the limiting cylinder 42 is higher than the lower end of the clearance groove 211.

[0071] By dividing the housing 21 into a base 212 and a middle plate 213, and setting the clearance groove 211 on the inner sidewall of the middle plate 213, it is easy to process the clearance groove 211. Furthermore, since the outer diameter of the fastener is smaller than the diameter of the mounting hole 421, the limiting cylinder 42 can be movably connected to the middle plate 213.
