Generally, the outer pot assembly 10 has a heating plate 18, and the heating plate 18 is located at the bottom of the receiving cavity 11. When the inner pot 60 is sleeved in the receiving cavity 11, the heating plate 18 contacts the bottom of the inner pot 60, and the inner pot 60 can be heated.

[0037] According to some embodiments of the present application, the pot body 100 also includes a sealing member 80, one end of which is connected to the outer pot assembly 10, and the other end of the sealing member 80 protrudes toward the side where the accommodating cavity 11 is located and is sleeved on the outside of the inner pot 60, so that the part of the sealing member 80 sleeved on the outside of the inner pot 60 is sealed between the outer pot 14 and the inner pot 60, preventing external water stains and impurities from falling into the bottom of the accommodating cavity 11 through the gap between the outer pot 14 and the inner pot 60, preventing the heating plate 18 at the bottom of the accommodating cavity 11 from being damaged by the water stains and impurities that fall into the accommodating cavity 11, and improving the electrical safety performance of the cooking appliance.

[0038] In addition, the portion of the seal 80 that is sleeved outside the inner pot 60 is constructed to be hollow, so that when the inner pot 60 is installed and removed, the hollow seal 80 can deform inward, having a large avoidance and deformation space, and can smoothly take and place the inner pot 60, which can effectively prevent the inner pot 60 and the seal 80 from getting stuck during the installation and removal process, thereby improving the convenience of assembly.

[0039] Referring to Fig. 3 to Fig. 6, further, the sealing member 80 includes a connecting portion 82 and a sealing portion 84, wherein the connecting portion 82 is fixedly matched with the outer pot assembly 10, and the sealing portion 84 is protruded toward the side where the accommodating cavity 11 is located, and is annularly sleeved outside the inner pot 60; wherein an annular hollow cavity 85 is formed inside the sealing portion 84. In this way, the sealing portion 84 is configured to be annularly sleeved outside the inner pot 60 to seal the gap between the inner pot 60 and the outer pot 14 in the entire circumferential direction, and at the same time, an annular hollow cavity 85 is formed inside the sealing portion 84 to provide deformation space in the entire circumferential direction of the inner pot 60 through the annular hollow cavity 85, so that the inner pot 60 is easy to install and disassemble.

[0040] Optionally, the connecting portion 82 is also annularly sleeved and connected to the radially outer side of the sealing portion 84, so that the sealing member 80 is annular as a whole and includes the sealing portion 84 located on the radially inner side and the connecting portion 82 located on the radially outer side, and the sealing member 80 is installed and fixed through the annular connecting portion 82. Optionally, the connecting portion 82 includes at least two sub-connecting pieces, and the at least two sub-connecting pieces are arranged at intervals along the circumferential direction of the sealing portion 84 on the radially outer side of the sealing portion 84, so that the sealing member 80 is installed and fixed through the at least two sub-connecting pieces.

[0041] In some specific embodiments, the transverse surface of the sealing portion 84 is in the shape of a circular ring, that is, the inner circumference of the sealing portion 84 is an arc surface, which can be more flexibly matched with the inner pot 60 and will not cause too much obstruction to the installation and removal of the inner pot 60. In other specific embodiments, the transverse surface of the sealing portion 84 is a multi-deformed ring, so that the surface of the sealing portion 84 in contact with the inner pot 60 can be constructed as a plane, which can increase the contact area between the sealing portion 84 and the inner pot 60 and improve the sealing performance.

[0042] According to some embodiments of the present application, the outer pot assembly 10 includes an outer shell 12, an outer pot 14 sleeved in the outer shell 12, and a support ring 16 connected between the outer shell 12 and the outer pot 14, wherein the outer pot 14 forms at least a portion of the accommodating cavity 11, and the support ring 16 encloses another portion of the accommodating cavity 11, that is, the outer pot 14 and the support ring 16 are combined together to form the accommodating cavity 11. Specifically, the support ring 16 is located on a side of the accommodating cavity 11 having an opening, and the inner pot 60 is inserted into the outer pot 14 from the opening of the accommodating cavity 11 through the support ring 16.

[0043] Furthermore, the connection portion 82 is disposed on the support ring 16, so that the connection portion 82 is mounted and connected through the support ring 16. The sealing portion 84 protrudes from the inner wall of the outer pot 14 along the radial direction of the outer pot 14, and the sealing portion 84 is squeezed between the inner pot 60 and the outer pot 14, so that the sealing portion 84 can extend into the accommodating cavity 11, and can be sleeved between the inner pot 60 and the outer pot 14 to seal the gap between the inner pot 60 and the outer pot 14, and prevent water stains and impurities from entering the gap between the outer pot 14 and the inner pot 60 and then flowing to the heating plate 18, so as to protect the heating plate 18.

[0044] Furthermore, a positioning column 161 is provided on the support ring 16, and the connecting portion 82 is sleeved on the positioning column 161, so that the seal 80 is limitedly installed by the protruding positioning column 161. It can be understood that in some other embodiments, the seal 80 and the support ring 16 can also be installed and fixed by gluing or screwing.

[0045] According to some embodiments of the present application, the support ring 16 has a first side facing the outer edge of the inner pot 60 and a second side opposite to the first side. Along the circumference of the support ring 16, a plurality of positioning posts 161 are arranged at intervals on the second side of the support ring 16, and the connecting portion 82 is sleeved on the plurality of positioning posts 161. In this way, the positioning posts 161 are arranged on the second side of the support ring 16, and the connecting portion 82 of the sealing member 80 is also arranged on the second side of the support ring 16 through the plurality of positioning posts 161, which will not affect the edge of the inner pot 60 on the first side of the support ring 16.

[0046] Furthermore, the edge of the outer pot 14 is supported and fixed on the second side of the support ring 16, and the connecting portion 82 is limited between the edge of the outer pot 14 and the support ring 16 along the axial direction of the positioning column 161. In this way, in addition to installing and fixing the seal 80 through the positioning column 161, the edge of the outer pot 14 is also used to limit the seal 80 along the axial direction of the positioning column 161, preventing the seal 80 from moving axially from the positioning column 161 and detaching from the positioning column 161, thereby improving the installation reliability of the seal 80.

[0047] Referring to FIGS. 5 to 7 , further, the support ring 16 includes a support portion 163 and a side wall 165 intersecting and connected with the support portion 163. The top surface of the support portion 163 located on the first side faces the edge of the inner pot 60. The bottom surface of the support portion 163 located on the second side is protrudingly provided with a plurality of positioning posts 161, so that the connection portion 82 of the sealing member 80 can be sleeved on the plurality of positioning posts 161 on the bottom surface of the support portion 163, and the connection portion 82 is fixed to the second side of the support ring 16. A buckle 167 is provided on the side wall 165, and the buckle 167 supports the edge of the outer pot 14. The connection portion 82 is sleeved on the positioning posts 161 and is located between the edge of the outer pot 14 and the bottom surface of the support portion 163. In this way, the edge of the outer pot 14 is supported and fixed by the buckle 167 on the side wall 165 of the support ring 16, and the connecting portion 82 is limited between the edge of the outer pot 14 and the bottom surface of the support portion 163, thereby realizing the limited installation of the sealing member 80.

[0048] During the installation process, the seal 80 is first sleeved on the positioning column 161 on the bottom surface of the support portion 163, and then the support ring 16 is assembled with the outer pot 14 and the outer shell 12, so that the edge of the outer pot 14 is buckled onto the buckle 167. At this time, the edge of the outer pot 14 can be blocked on the side of the connecting portion 82 facing away from the supporting portion 163, thereby further limiting the connecting portion 82.

[0049] 6 and 7 , in some embodiments, the buckle 167 and the positioning column 161 are staggered along the axial direction of the outer pot 14, so that when the connecting portion 82 of the seal 80 is sleeved on the positioning column 161, the buckle 167 will not interfere, which facilitates the installation of the seal 80. Specifically, a plurality of buckles 167 and a plurality of positioning columns 161 are arranged in an interlaced manner along the circumferential direction of the outer pot 14, so that when installing the seal 80, it can be directly sleeved onto the positioning column 161 from the outside of the positioning column 161, preventing the buckle 167 from affecting the installation of the seal 80.

[0050] In addition, there is a gap between the buckle 167 and the positioning column 161 along the axial direction of the outer pot 14, so that the edge of the outer pot 14 can be installed in the gap between the positioning column 161 and the buckle 167, and the installation gap is reserved for the edge of the outer pot 14. When the edge of the outer pot 14 is buckled into the upper part of the buckle 167, the edge of the outer pot 14 is just located below the positioning column 161, and the connecting portion 82 sleeved on the positioning column 161 can be axially limited to prevent the connecting portion 82 from being separated from the positioning column 161 in the sleeved direction.

[0051] According to some embodiments of the present application, the present application further provides a pot body 100 as described in any of the above embodiments, the pot body 100 includes an outer pot assembly 10, an inner pot 60 and a sealing member 80, a receiving cavity 11 is formed on the outer pot assembly 10, the inner pot 60 and the outer pot assembly 10 are detachably assembled, and the inner pot 60 is at least partially sleeved in the receiving cavity 11, so that the inner pot 60 can be flexibly taken out for food preparation, and when cooking is required, the inner pot 60 is placed in the receiving cavity 11, and the inner pot 60 can be heated and cooked. Generally, the outer pot assembly 10 has a heating plate 18, and the heating plate 18 is located at the bottom of the receiving cavity 11.
