For example, in the present embodiment, the first contact portion 141 extends from the upper end of the first connecting portion 144 in a direction approaching the center line of the heat preservation cover 110, and the first contact portion 141 is for contact with the middle ring portion 132 and/or the inner ring portion 131. As a preferred embodiment, the middle ring portion 132 of the heating device 130 is provided with a heating wire, and the first contact portion 141 of the heat transfer member 140 is preferably in contact with the middle ring portion 132. For example, fig. 8 shows the contact area 134 of the middle ring portion 132 of the heating device 130 with the heat transfer member 140.

As an alternative embodiment, the surface of the second contact part 142 for contacting the inner pot 150 is flush with the inner side profile of the heat preservation cover 110 or is located outside the inner side profile of the heat preservation cover 110 when the inner pot 150 is removed. Thus, the second contact portion 142 is provided not to protrude from the inner surface of the heat preservation cover 110, further improving the safety of use and improving the visual experience.

It should be noted that, since the pivoting direction of the second contact portion 142 is away from the inner pan 150 when the inner pan 150 is taken out, in order to avoid the second contact portion 142 from being excessively pivoted to contact with the housing 101 or other structural components, it is preferable to provide the limiting portion 115 on the heat insulation cover 110. Referring to fig. 5 and 6, the limiting portion 115 protrudes from the outer surface of the heat insulation cover 110 and at least partially shields the second opening 112, and when the inner pot 150 is removed, the second contact portion 142 interferes with the limiting portion 115.

Specifically, the stopper 115 includes a base portion 117 and a blocking portion 118, wherein the base portion 117 extends in a direction away from the heat preservation cover 110 for providing a depth to which the second contact 142 pivots outwardly. The blocking portion 118 extends from the base portion 117 in a direction toward the middle of the second opening 112 to form a partial shielding of the second opening 112. Thus, when the second contact portion 142 is pivoted outward, it is restrained by the blocking portion 118 after being pivoted by a certain angle.

As a preferred embodiment, the stopper 115 is configured as a flange provided at the edge of the second opening 112. More preferably, both side edges of the second opening 112 in the circumferential direction of the heat preservation cover 110 are provided with two stopper portions 115.

Fig. 9 shows that the first contact portion 241 abuts against the heating device 130, and the second contact portion 142 abuts against the inner pan 150. Fig. 10 shows a case where the inner pan is lifted up, and the second contact portion 142 is automatically separated from the sidewall of the inner pan 150.

Specifically, in the present embodiment, the heat transfer member 140 is in contact with the outer ring portion 133 of the heating device 130, for example, fig. 13 shows a contact area 234 of the outer ring portion 133 of the heating device 130 and the heat transfer member 140. In this case, the first contact portion 241 extends from the upper end of the first connection portion 144 in a direction away from the center of the heat preservation cover 110. In this case, the first contact portion 241 has a surface disposed obliquely so as to face the outer ring portion 133 of the heating device 130. Thus, the first opening 211 having a smaller size is required to allow the first contact portion 241 to pass smoothly. In this way, the fitting portion 213 may be spaced apart from the first opening 211, and the smaller opening is advantageous for maintaining the strength and the insulation effect of the insulation cover 110. The engaging portion 213 may be a flange provided at the bottom wall of the heat insulating cover 110, that is, a further opening is provided at a distance from the first opening 211, and the engaging portion 213 is configured as a flange of the further opening.
