Further, the bottom of the inner pan 102 is further provided with a bottom cover 108, the bottom wall of the inner pan 102 and the bottom cover 108 jointly enclose a sealed cavity, the heating element 104 is arranged in the sealed cavity, the first coupler 106 is at least partially located inside the sealed cavity, and the electrical components of the inner pan 102 are also located in the sealed cavity, so that the waterproof and dustproof functions can be achieved. Further, the inner pot assembly 100 further comprises a pressure plate 126 disposed on the first coupler 106, the pressure plate 126 being configured and adapted to secure the sensor 124. Specifically, the sensor 124 may be a temperature sensor 124, and when the temperature of the inner pot 102 reaches a preset value, an alarm signal is sent or a power supply circuit of the cooking device is automatically cut off, so as to avoid safety accidents, in addition, the sensor 124 may also be a displacement sensor 124, and when the inner pot assembly 100 moves downwards, a deviation occurs, that is, when the downward movement amounts of different positions of the inner pot assembly 100 are inconsistent, an alarm signal is sent or a power supply circuit of the cooking device is automatically cut off, so as to avoid safety accidents of the cooking device during pressure relief. In addition, the pressing plate 126 may be directly mounted on the first coupler 106, or may be provided as an integrated structure integrally formed with the first coupler 106, so as to improve the connection strength between the sensor 124 and the inner pan 102, so that the connection is more stable.

Wherein the bottom plate 112 is disposed between the pan body 110 and the heating member 104, and the heating member 104 and the first coupler 106 are both disposed on the bottom plate 112. On one hand, the bottom plate 112 can prevent the heating element 104 and the first coupler 106 from being directly connected with the inner pan 102, prevent the heating element 104 and the first coupler 106 from damaging the inner pan 102 due to the connection process, and reduce the difficulty of connecting the heating element 104 and the first coupler 106; on the other hand, the bottom plate 112 can prevent the heating element 104 from directly contacting the inner pot 102, so that the heat generated by the heating element 104 is transferred to the inner pot 102 through the bottom plate 112, thereby ensuring that the bottom of the inner pot 102 is uniformly heated and ensuring the cooking effect.

Specifically, the pan body 110 may be a stainless steel pan body, and the bottom plate 112 may be an aluminum bottom plate. The bottom plate 112 is fixed on the pan body by welding or screws; the first coupler 106 is fixed to the base plate 112 by screws.

Further, an avoiding gap 128 is formed in the bottom cover 108, and the first coupler 106 is disposed opposite to the avoiding gap 128, so that the insertion part of the first coupler 106 is located outside the sealed cavity. It is ensured that the first coupler 106 can cooperate with an external coupler (i.e., the second coupler 202) to supply power to the electrical components in the inner pot 102. Specifically, the escape notch 128 is provided at a central position of the bottom cover 108.

Further, as shown in fig. 5, the cooking apparatus further includes: and a second coupler 202 arranged on the outer pot 200, wherein the second coupler 202 is suitable for being plugged with the first coupler 106. The first coupler 106 cooperates with the second coupler 202 to provide power to the heating element 104 to ensure operation of the cooking appliance.
