It should be noted that, although a partial structure of the cooking appliance 100 is schematically described at this time, these lists are only exemplary and cannot be taken as a structural limitation of the cooking appliance 100 of the embodiment of the present invention.

In the present embodiment, the pot body assembly further includes an outer pot 110 (or may also be referred to as a heat insulation cover), the outer pot 110 at least partially forms a receiving portion capable of receiving the inner pot 141, which can insulate the inner pot, and a heating assembly for heating the inner pot 141 in the cooking appliance 100 may be disposed on the outer pot 110, for example, the heating assembly may be disposed at the bottom of the outer pot 140.

Specifically, as shown in fig. 2 and 3, the outer pot 110 includes a bottom wall 111 and a sidewall 112 extending upward from a circumferential edge of the bottom wall 111. In the present embodiment, the middle plate 120 has an opening to which the top of the sidewall 112 of the outer pot 110 can be connected, whereby the inner pot 141 can be put into the receiving part formed by the outer pot 110 through the opening of the middle plate 120.

Further, the top outer side of the side wall 112 away from the bottom wall 111 is provided with a projection 113 and a catching portion 114 which project outwardly in the radial direction of the pot body assembly. As shown in fig. 4 and 5, the inner side of the middle plate 120 is provided with a support structure and a stopper 121 extending outward in the radial direction of the pot body assembly.

As one implementation, the position-limiting portion 121 may be integrally formed on the middle plate 120, and both the middle plate 120 and the position-limiting portion 121 may be made of a non-metal material, such as plastic. The clip portion 114 may be constructed of a metal material having elasticity to ensure sufficient elastic deformability of the clip portion.

In this embodiment, when it is required to fix the outer pot 110 and the middle plate 120 together, the middle plate 120 may be sleeved on the top periphery of the outer pot 110, so that the outer pot 110 rotates relative to the middle plate 120 along the first rotation direction, and the protruding portion 113 abuts against the supporting structure, and the clamping portion 114 abuts against the limiting portion 121 to limit the outer pot 110 from rotating relative to the middle plate 120 in the direction opposite to the first rotation direction.

It can be understood that when the outer pot 110 rotates in the first rotating direction relative to the middle plate 120, as the rotating angle of the outer pot 110 increases, interference between the clamping portion 114 and the limiting portion 121 is gradually generated, and the amount of interference gradually increases, in this process, since the limiting portion 121 has elasticity, it can be elastically deformed inwards in the radial direction of the pot body assembly. When the outer pot 110 rotates to the right position relative to the pot body assembly, the protruding portion 113 abuts against the supporting structure, the clamping portion 114 completely rotates over the limiting portion 121, and the clamping portion 114 abuts against the limiting portion 121, so that the outer pot 110 is effectively limited from rotating in the direction opposite to the first rotating direction relative to the middle plate 120.

In the present embodiment, the cross section of the stopper portion 121 in the direction perpendicular to the height direction of the pot body assembly is configured in a U shape. Specifically, as shown in fig. 5, the limiting portion 121 includes a limiting wall 123, a connecting wall 125 and a supporting wall 124 which are connected in sequence, and one end of the limiting wall 123 far away from the connecting wall 125 is connected to the middle plate 120, and one end of the supporting wall 124 far away from the connecting wall 125 is connected to the middle plate 120. Therefore, the two ends of the U shape of the limiting portion 121 can be fixed on the middle plate 120, the structural strength of the limiting portion 121 is effectively improved, and the reliability of the limiting portion is improved.

Further, the limiting wall 123 has a limiting surface 122 at a side away from the supporting wall 124, the limiting surface 122 extends along the radial direction of the cooker body assembly, and the clamping portion 114 can abut against the limiting surface 122 after the outer pot 110 is mounted to the middle plate 120. It can be understood that the plane of the limiting surface 122 extends through the center line of the cooker body assembly in the height direction thereof, so that even if the elastic deformation of the clamping portion 114 generates a slight change, the clamping portion 114 can be effectively abutted against the limiting surface 122, thereby ensuring that the cooker body assembly has sufficient stability.

Further, the connecting wall 125 is provided extending in the circumferential direction of the pot body assembly, and the cross section of the connecting wall 125 in the direction perpendicular to the height direction of the pot body assembly is configured substantially in an arc shape. Therefore, the connecting wall 125 has an arc structure recessed toward the middle plate 120, and when the outer pot 110 is rotatably mounted to the middle plate 120, the connecting wall 125 does not interfere with the outer side surface of the outer pot 110, thereby ensuring that the outer pot 110 can normally rotate relative to the middle plate 120, and enabling the outer pot 110 and the middle plate 120 to be smoothly connected together.

Preferably, in order to be able to secure the stopper portion 121 with sufficient structural strength, the support wall 124 may be provided extending in a radial direction of the pot body assembly or in a direction parallel to the stopper wall 123.

As shown in fig. 3, the top periphery of the side wall 112 away from the bottom wall 111 is provided with a terrace portion 118 extending outward in the radial direction of the pot body assembly, and the circumferential edge of the terrace portion 118 is provided with a burring portion 117 extending downward in the height direction of the pot body assembly. Wherein one end of the catching portion 114 is connected to the burring portion 117, and the remaining portion of the catching portion 114 is separated from the burring portion 117 and protrudes outward in the radial direction of the pot body assembly.

It is to be understood that in the present embodiment, the platform part 118 is provided at the top of the side wall 112 in the circumferential direction of the pot body assembly, and moreover, the platform part 118 and the burring part 117 together form an annular projection structure which is outwardly projected in the radial direction of the pot body assembly and is configured substantially in an L-shape in cross section. Wherein one end of the catching portion 114 is connected to the burring portion 117, and the remaining portion is in a separated state and protrudes outward in the radial direction of the pot body assembly.

In the installation process, when the clamping portion 114 interferes with the limiting portion 121, the separating portion of the clamping portion 114 can be elastically deformed inwards along the radial direction of the cooker body assembly, after the outer pot 110 is installed in place relative to the middle plate 120, the clamping portion 114 does not interfere with the limiting portion 121 any more, the clamping portion 114 can elastically reset and is abutted to the limiting surface 122 of the limiting portion 121, and therefore the outer pot 110 is prevented from rotating reversely relative to the middle plate 120. In addition, when the outer pot 110 needs to be detached from the middle plate 120, the clamping portion 114 can be pressed, so that the clamping portion 114 is elastically deformed inwards along the radial direction of the cooker body assembly, the clamping portion 114 is not abutted to the limiting surface 122 any more, then the outer pot 110 rotates reversely relative to the middle plate 120, and finally the outer pot 110 and the middle plate 120 are separated.

As one implementation, a stamping may be adopted such that a portion of the flanging portion 117 protrudes outward in the radial direction of the pot body assembly to form the clipping portion 114.

As shown in fig. 3, in the present embodiment, the snap-in portion 114 includes an extension section 115 and a bending section 116, the extension section 115 connects the flanging section 117 and the bending section 116, the extension section 115 extends from the side wall 112 in an oblique direction to a direction away from the side wall 112, and one end of the bending section 116 is connected to one end of the extension section 115 away from the flanging section 117, and the other end of the bending section 116 is formed as a free end extending in a circumferential direction of the pot body assembly. It is understood that the catching portion 114 includes an extension section 115 and a bent section 116 provided in a circumferential direction of the pot body assembly, wherein one end of the extension section 115 is connected to the flange, and one end of the bent section 116 is formed as a free end.

In order to ensure that the clamping portion 114 can be elastically deformed effectively and improve the structural strength of the clamping portion 114, in the present embodiment, the bent section 116 is inclined relative to the extended section 115 toward one side of the outer pot 110, for example, an included angle between the extended section 115 and the bent section 116 is 120 ° to 160 °.

Preferably, the burring part 117 protrudes outward in the radial direction of the pot body assembly to form the protruding part 113. As one implementation, the burring 117 may be punched in such a manner that a portion of the burring 117 protrudes outward in the radial direction of the pot body assembly to form the protruding part 113.

The outer pot 110 can be fixedly connected to the middle plate 120 by a rotating manner, and in order to improve the stability of the connection of the outer pot 110 and the middle plate 120, the number of the clamping portions 114 is at least two, and the clamping portions 114 are arranged at intervals in the circumferential direction of the cooker body assembly. For example, in the present embodiment, the number of the engaging portions 114 is two, and the two engaging portions 114 are symmetrically disposed on both sides of the inner pot 141 in the circumferential direction and can be abutted against the two stopper portions 121 correspondingly disposed on the middle plate 120.
