As shown in fig. 1, 2, 3 and 6, the cooking appliance of the first embodiment includes: a base 10, a container 20, a drive mechanism 30, and a stirring structure 90. The container 20 can be attached to the base 10. The driving mechanism 30 is disposed on the base 10, the driving mechanism 30 includes a motor 31 and a first transmission member 32, and the first transmission member 32 includes a first plate 322 and a flange 321 disposed on the first plate 322. The stirring structure 90 is disposed on the container 20, the stirring structure 90 includes a second transmission member 40, and the second transmission member 40 includes a second plate 42 and a lug 41 disposed on the second plate 42. In the present embodiment, the motor 31 drives the stirring structure 90 to rotate through the cooperation of the flange 321 and the lug 41.

By applying the first technical solution of the present embodiment, the first transmission member 32 includes a first plate 322 and a flange 321 disposed on the first plate 322. The second transmission member 40 includes a second plate 42 and a lug 41 disposed on the second plate 42. The motor 31 drives the stirring structure 90 to rotate through the matching of the flange 321 and the lug 41. Thus, the first plate 322 and the flange 321 have simple structure, can be formed by processes such as stamping, shearing and the like without using a die-casting process, and have simple forming process, easy processing and lower cost. Similarly, the second plate 42 and the lug 41 can be formed by stamping, cutting, etc. without using a die-casting process, so that the forming process is simple and the cost is low. Therefore, the technical solution of the first embodiment can effectively solve the problem of high manufacturing cost of the connector of the cooking appliance in the related art. In the first embodiment, when the container 20 and the second transmission piece 40 are placed on the base 10, since the projection of the flange 321 of the first transmission piece 32 and the lug 41 of the second transmission piece 40 on the first plate 322 only occupies a small portion of the surface of the first plate 322, the lug 41 and the flange 321 are not easily interfered with each other.

In the first embodiment, as shown in fig. 1, the stirring structure is disposed at the bottom of the container, and the transmission member is located at the bottom of the base. In other embodiments not shown in the figures, the stirring structure can also be provided on the side of the container, and correspondingly the transmission member on the side of said base body.

As shown in fig. 3 and 6, the burring 321 and the lug 41 are formed by press-forming. In this way, the flanging 321 and the lug 41 can be processed more simply by stamping, and the processing efficiency is higher compared with the die-casting in the related art.

In the present embodiment, specifically, the forming process of the turned-up edge 321 is as follows: a circular raw material plate is selected, an edge portion of the circular raw material plate is punched along the axial direction to form a notch, the arc-shaped structure at the position of the notch is punched, the bent edge 321 is obtained after bending, and the rest portion of the raw material plate forms a first plate body 322. The lug 41 is formed as follows: on a circular or other shaped raw plate, the second plate body 42 and the lugs 41 attached at the edges of the second plate body 42 are directly obtained by stamping.

The first transmission member 32 of the first embodiment is made of metal material with a thickness of 0.5mm to 3 mm. In the case where the container 20 is placed in the base 10, the thickness makes the flange 321 thinner, so that the possibility of contact between the bottom surface of the lug 41 and the top surface of the flange 321 is reduced, and the possibility of interference occurring when the drive rib of the upper connector and the drive rib of the lower connector are in contact in the related art is greatly reduced. The width of the lug 41 is preferably 3mm to 8 mm. The thickness of the second transmission member 40 of the present embodiment may be 0.5mm to 3 mm. The thickness of the second transmission member 40 is thus small, which can reduce the weight of the stirring structure 90.

As shown in fig. 3 and 5, a fold is formed between the flange 321 and the first plate 322, and a distance between a first end of the fold and a rotation center of the first plate 322 is smaller than a distance between a second end of the fold and the rotation center of the first plate 322. The structure can increase the contact area of the lug 41 and the flanging 321, and improve the transmission stability.

As shown in fig. 3, one end of the turned edge 321 facing the second transmission member 40 has a guiding arc 323, and the distance from the guiding arc 323 to the first plate 322 gradually decreases in the direction from the outside to the inside of the first plate 322. The guiding arc 323 is disposed in the process of matching the second transmission member 40 with the first transmission member 32, and the second transmission member 40 can fall into the upper portion of the first plate 322 along the guiding arc 323, so that the assembly is convenient.

As shown in fig. 8, there are two flanges 321, two flanges 321 are arranged in central symmetry, two lugs 41 are arranged, and the two flanges 321 and the two lugs 41 are arranged in one-to-one correspondence. The two flanges 321 make it possible to increase the structural strength of the first transmission piece 32, and the two lugs 41 make it possible to increase the structural strength of the second transmission piece 40. This can prolong the transmission life of the first transmission member 32 and the second transmission member 40.

In other embodiments not shown in the drawings, the number of the flanges may be one or more than three, which can improve the structural strength of the first transmission member, and the number of the lugs may be one or more than three, which are arranged in one-to-one correspondence with the flanges. This can improve the structural strength of the second transmission member.

As shown in fig. 4, the flange 321 is perpendicular to the first plate 322. The vertical arrangement can increase the contact area between the lug 41 and the flange 321, and improve the transmission stability.

As shown in fig. 5 and 8, the turned-over edge 321 is offset from the first plate 322 in a predetermined radial direction M, the lug 41 extends in the radial direction of the second plate 42, and in the case of the engagement of the turned-over edge 321 with the lug 41, the turned-over edge 321 is in face-to-face engagement with the lug 41. This allows the flange 321 to have a sufficiently large contact surface with the lug 41, so that the transmission of the first transmission member 32 and the second transmission member is more smooth. The predetermined radial direction M is a specific one of the radial directions of the first plate body 322, as shown in fig. 5.

As shown in fig. 6, the lug 41 is bent or curved. In this way, the bent or curved structure can enhance the structural strength of the second transmission piece 40, so that the lug 41 and the second plate 42 are not easily damaged.

As shown in fig. 1, a first through hole 324 is formed in the first plate 322, and the first plate 322 is sleeved on the output shaft of the motor through the first through hole 324.
