As shown in FIGS. 1 and 6, in any one of the above-mentioned embodiments, furthermore, the inner pot assembly comprises: an inner pot; a heating element 128, being arranged at a bottom wall of the inner pot; and a bottom cover 200, being arranged at a bottom of the inner pot, and connected with the inner pot, wherein, the bump 105 is arranged at the bottom cover 200, the bottom wall and the bottom cover 200 of the inner pot together form a sealed cavity, the heating element 128 is arranged in the sealed cavity, and electrically connected with the first coupler 102, and the first coupler 102 is located at least partially inside the sealed cavity.

In this embodiment, the bottom cover 200 is arranged at the bottom of the inner pot, the bottom wall and the bottom cover 200 of the inner pot are enclosed into a sealed cavity. The bump 105 is arranged at the bottom cover 200 to facilitate the processing of the bump 105, the heating element 128 is arranged in the sealed cavity, and the heating element 128 is electrically connected with the first coupler 102. During the use of the inner pot, the first coupler 102 is used in a way that cooperates with the second coupler 110 to supply power to the heating element 128, and the heating element 128 works to generate heat to cook the food in the cooking cavity. A part of the structure of the first coupler 102 is located in the sealed cavity, and the electrical components of the inner pot are also located in the sealed cavity.

As shown in FIGS. 1 and 2, in any one of the above-mentioned embodiments, furthermore, a bottom plate 202 is arranged between the pot body and the heating element 128, and both the heating element 128 and the first coupler 102 are arranged at the bottom plate 202. On the one hand, the bottom plate 202 can prevent the heating element 128 and the first coupler 102 from being directly connected to the pot body, avoid the damage to the pot body caused by the connection process of the heating element 128 and the first coupler 102, and reduce the difficulty of connecting the heating element 128 and the first coupler 102. On the other hand, the bottom plate 202 can avoid the direct contact between the heating element 128 and the pot body, the heat generated by the heating element 128 is transferred to the pot body through the bottom plate 202, to ensure that the bottom of the pot body is evenly heated and the cooking effect is ensured.

Specifically, the pot body is made of stainless steel inner pot, and the bottom plate 202 is made of aluminum bottom plate. The bottom plate 202 is fixed on the pot body by welding or screws; the first coupler 102 is fixed on the bottom plate 202 by screws.

As shown in FIGS. 3 and 4, in any one of the above-mentioned embodiments, furthermore, the cooking device further comprises: a sensor 204, being arranged at the inner pot; and a pressure plate, being arranged at the first coupler 102, the pressure plate being configured to be adapted to fix the sensor 204.

In this embodiment, the sensor 204 is arranged at the inner pot, the pressure plate is arranged at the first coupler 102, and is configured to be adapted to fix sensor 204. Specifically, the sensor 204 can be a temperature sensor, and pressure is applied to the sensor 204 through a pressure plate, the sensor 204 and the inner pot assembly 100 fit together, which can ensure that the sensor 204 and the inner pot assembly 100 are in firm contact and fit tightly. This ensures that the temperature of the medium inside the inner pot assembly 100 can be quickly and accurately transferred to the sensor 204; the sensor 204 can accurately measure the temperature and improve the performance of the product.

As shown in FIGS. 3 and 4, in any one of the above-mentioned embodiments, furthermore, the bottom plate 202 is provided with a fixation column 206 extending downward from the bottom wall of the bottom plate 202. The first coupler 102 is provided with a fixation hole 208, the fixation column 206 is inserted into the fixation hole 208, and the connection member is connected to the fixation column 206 through the fixation hole 208. Therefore, the first coupler 102 is fixed on the bottom plate 202 through the connection member, which can not only make the connection between the first coupler 102 and the bottom plate 202 firm, but also facilitate the installation and disassembly of the first coupler 102.

Specifically, the connection member can be a screw, and the screw connection is convenient for installation, which saves costs, simplifies the production process, improves production efficiency, and facilitates subsequent disassembly and maintenance.
