The pot body 10 includes a pot body 11, a protrusion 12 and a rotation shaft base 13, and the protrusion 12 and the rotation shaft base 13 are disposed at two opposite sides of the pot body 11. The upper surface of the protruding part 12 is higher than the upper surface of the pot body 11, and a groove 14 extending along the circumferential direction of the pot body 11 is arranged on the upper surface of the pot body 11. The pot cover 20 is connected with the pot body 10 through a connecting shaft, the connecting shaft is installed in the rotating shaft seat 13, and a concave part matched with the convex part 12 is arranged on the pot cover 20. In the present embodiment, in the case that the pot cover 20 is covered on the pot body 10, the boundary 40 between the pot cover 20 and the pot body 10 corresponds to the side of the pot cover 20, and a part of the structure of the pot cover 20 is protruded into the groove 14.

With the technical solution of the present embodiment, since the pot lid 20 is provided with the concave portion which is matched with the convex portion 12, the overall size of the pot lid 20 is reduced compared with that of the pot lid in the related art, and the weight of the pot lid can be reduced. In addition, in the case that the lid 20 is covered on the pot body 10, a boundary 40 between the lid 20 and the pot body 10 corresponds to a side surface of the lid 20, and a part of the structure of the lid 20 is protruded into the groove 14. Because the position of the dividing line 40 is adjusted, and meanwhile, part of the structure of the pot cover 20 extends into the groove 14, the exposed height of the pot cover 20 is reduced under the condition that the whole height of the cooking appliance is basically kept unchanged, so that the cooking appliance has a compact whole structure and exquisite appearance.

Note that the "opposite sides" are sides in the direction of the arrow in fig. 3, and the protrusion 12 and the rotating shaft base 13 may be symmetrically disposed, or the protrusion 12 may be offset from the symmetric position of the rotating shaft base 13. The upper surface of projection 12 is the surface where the highest point of projection 12 is located in the direction of the longitudinal central axis of pot 10. The pot cover 20 is covered on the pot body 10, a middle plate is formed at the top of the pot body 11, and the upper surface of the pot body 11 is the upper surface of the middle plate.

Therefore, the positions of the first hook 31 and the second hook 32 are not easy to deform, which is convenient for the first hook 31 and the second hook 32 to cooperate, so that the first hook 31 is more smoothly buckled on the second hook 32.

As shown in fig. 1 and 5, in the present embodiment, the boundary 40 includes a first line segment 41, a second line segment 42, a third line segment 43, a fourth line segment 44, and a fifth line segment 45 connected in this order, the third line segment 43 is higher than the first line segment 41 and the fifth line segment 45, the second line segment 42 is disposed obliquely with respect to the first line segment 41 and the third line segment 43, and the fourth line segment 44 is disposed obliquely with respect to the fifth line segment 45 and the third line segment 43. In the case that the lid 20 is covered on the pot body 10, the second line segment 42 and the fourth line segment 44 are arranged so that the protrusion 12 is hidden in the first recess 21, thereby preventing a gap from being formed at the top of the lid 20, forming a complete boundary line 40 on the outer surface of the cooking utensil, and further integrating the pot body 10 and the lid 20 into a whole.

As shown in fig. 10 and 11, in the present embodiment, the pot body 11 includes a base 111 and a housing 112 disposed on the base 111, the housing 112 includes a middle plate 113 disposed corresponding to the pot cover 20, and the protrusion 12 and the rotating shaft base 13 are disposed on the middle plate 113. The convex part 12 and the rotating shaft seat 13 are easy to process and realize. In the present embodiment, the groove 14 is provided on the middle plate 113.

As shown in fig. 5 and 10, in the present embodiment, the housing 112, the boss 12, and the spindle base 13 are of an integrally molded structure. The integrated into one piece structure is through injection molding processing, the shaping of being convenient for like this.

As shown in fig. 4 to 6, in the present embodiment, the lid 20 is assembled by the face cover 23, the liner 22 and the handle 50, and the lid 20 is combined with the pot body 10. The pot cover 20 is exposed, so that the thickness of the pot cover 20 is reduced. Under the condition that the pot cover 20 is covered on the pot body 10, the whole pot cover 20 moves downwards to divide the exposed surface of the pot cover 20 into two sections, namely an exposed section M and a hidden section N. The exposed section M is the outer side surface of the surface cover 23, the step structure 25 of the liner 22 is the hidden section N, and the whole exposed part of the pot cover 20 is equal to the sum of the exposed section M and the hidden section N. Under the condition that the overall height of the pot cover 20 is not changed, the distance between the exposed section M and the hidden section N is only changed, for example, the overall exposed thickness of the pot cover 20 is 76mm, the exposed section M can be designed to be 64mm, the hidden section N is designed to be 12mm, after the cooking utensil is closed, the pot cover 20 is only exposed to the height of 64mm, and 12mm less than the overall unexposed thickness of the pot cover 20, so that the cooking utensil is overall simple.
