In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

As shown in fig. 1, 2, 8 to 11, the cooking appliance of the present embodiment includes: a base body 10, a first container 21, a second container 22, and a driving mechanism 30. The first container 21 and the second container 22 can be attached to the base 10, and the second container 22 has a stirring structure 90. The driving mechanism 30 is disposed on the substrate 10, and the driving mechanism 30 includes a power source 31 and a transmission member 32 driven by the power source 31. In the first embodiment, the transmission member 32 is movably connected to the power source 31 through a screw structure, and the transmission member 32 can be located at a docking position for docking with the stirring structure 90 and at an evacuation position for evacuating the first container.

By applying the technical solution of the present embodiment, the transmission member 32 is engaged with the power source 31 through a threaded structure, so that the transmission member 32 has a descending position and a lifting position. When the transmission member 32 is rotationally moved to the descending position through the screw structure, the first container 21 without the stirring structure can be mounted on the base body 10, at this time, the transmission member 32 can avoid the first container 21, and when the transmission member is moved away, the transmission member 32 is located at the avoiding position, and the transmission member 32 does not interfere with the first container 21. When the transmission member 32 rotates to the lifting position through the screw structure, the second container 22 can be mounted on the base 10, the transmission member 32 is connected to the stirring structure 90, and the power source 31 drives the transmission member 32 to rotate to drive the stirring structure 90 to rotate. Therefore, the cooking appliance of the embodiment can use the first container without the stirring structure and the second container with the stirring structure, thereby effectively solving the problem that the common container cannot be used due to the interference of the lower coupler and the common container in the related art.

In an embodiment not shown in the figures, the transmission member is detachably connected to the power source through a threaded structure, and when the transmission member is assembled into the base body through the threaded structure, the transmission member can be located at a butt joint position where the transmission member is in butt joint with the stirring structure. The driving member can be removed from the base body when separated from the power source, and the driving member does not interfere with the first container.

It should be noted that: the base body is generally a pot body or a base, and the container can be an inner container or a cup body. The above-mentioned "escape" means that the transmission member 32 can move to make room, such as downward (when the transmission member is disposed below the container) or sideways (when the transmission member is disposed on the side of the container). In this way, the first container 21 can be placed in the base body without interfering with the transmission elements. The butt joint refers to that the transmission part and the stirring structure can be spliced and matched and can synchronously rotate.
