The details of the respective components and the connection relationship therebetween will be described in turn.

As shown in fig. 1, the cooking appliance 100 mainly includes a pot body 110 and a lid 120. The pot body 110 is substantially in a rounded rectangular parallelepiped shape and has a cylindrical inner pot receiving portion into or from which the inner pot 111 can be freely put or taken out to facilitate cleaning of the inner pot 111. The upper surface of the inner pot has a circular opening for containing materials to be heated, such as rice, soup, etc., into the inner pot. The cooker body may include therein a heating means for heating the inner pot. The cover 120 has a substantially rounded rectangular parallelepiped shape and substantially corresponds to the shape of the pot body. The cover body is pivotally connected to the pot body in an openable and closable manner and is used for covering the pot body. When the cover 120 is covered on the pot body 110, a cooking space is formed between the cover 120 and the inner pot 111.

As shown in fig. 2 to 4, a motor 150 is provided on the cover 120, and the motor 150 is provided with a motor shaft 151, and the motor shaft 151 is provided with a ring of recesses 152 (described later) along a circumferential direction thereof.

The second link 144 has a receiving portion 141 provided therein, and a plurality of second teeth 142 corresponding to the number of the first teeth 132 are provided on an inner surface of the receiving portion 141. The plurality of first teeth 132 and the plurality of second teeth 142 are each disposed evenly in the circumferential direction. The protruding portion 131 provided with the first tooth 132 may be inserted into the accommodating portion 141 provided with the second tooth 142, in an inserted state, the central axes of the first connecting member 130 and the second connecting member 144 are on the same axis, the first tooth 132 enters a guide region between the plurality of second teeth 142 in the accommodating portion 141, when the motor 150 drives the first connecting member 130 to rotate, the first tooth 132 rotates, and through idling in the guide region by an angle of 0 to 90 degrees, the tooth surface of the first tooth 132 contacts the tooth surface of the second tooth 142, as shown in fig. 8, so as to drive the second tooth 142 to rotate, and further drive the second connecting member 144 to rotate. Preferably, the number of first and second teeth is 2-6, for example 4 as shown in fig. 7, but a person skilled in the art may also provide other numbers of first and second teeth, for example 7 or 8, etc.

It is understood that, in the process of engaging the first and second connecting

members

130 and 144, a situation may occur in which the first and

second teeth

132 and 142 collide in the vertical direction, and in order to smoothly engage the first and second connecting

members

130 and 144, as shown in fig. 7, the lower end of the first tooth 132 and the upper end of the second tooth 142 are provided with

guide portions

132a and 142a, respectively. Preferably, the cross sections of the

guide parts

132a and 142a in the vertical direction are both isosceles triangles, so that when the first tooth 132 contacts with the second tooth 142, the guide part 132a slides down along the guide part 142a, and thus smoothly enters the accommodating part 141. Of course, in other embodiments not shown, the

guide portions

132a, 142a may also be other shapes, such as circular arcs and the like.

Although the protrusion 131 is disposed on the first connector 130 and the receiving portion 141 is disposed on the second connector 144 in the illustrated embodiment, it will be understood by those skilled in the art that the positions of the protrusion 131 and the receiving portion 141 may be interchanged, or other suitable engagement means may be used for the first connector 130 and the second connector 144.

As shown in fig. 9, the agitating body 143 is detachably coupled below the second coupling member 144. Specifically, the second connecting member 144 is provided with two opposite positioning posts 146, and the stirring main body 143 is provided with a guiding groove 147 and a positioning groove 148 which are communicated with each other. The guide groove 147 and the positioning groove 148 communicate in a generally L-shaped pattern, and the positioning post 146 can follow the guide groove 147 into the positioning groove 148 to be suspended on the positioning groove 148. In this way, when the second connecting member 144 rotates, the positioning column 146 thereon can push the positioning slot 148 on the stirring body 143, so as to drive the positioning slot 148 to rotate together, thereby rotating the stirring body 143.

The stirring body 143 is provided with two stirring blades 145. As shown in fig. 2 to 3, it is preferable that the agitating blades 145 are respectively located at both ends of the agitating body 143 and extend in opposite directions, thereby achieving uniform agitation. It is further preferred that the sum of the radial dimensions of the two stirring blades 145 is close to the inner diameter of the inner pan 111, that is, the radially outermost ends of the stirring blades 145 are close to the inner surface of the inner pan 111 when the stirring body 143 is put in place. This scheme is through making the radial dimension who is responsible for carrying out the stirring function's stirring vane be close the inside diameter of interior pot, can realize better stirring effect.

As shown in fig. 1 to 4 and 10, the cooking apparatus 100 further includes a support 160.
