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 to 3, the cooking appliance of the present embodiment includes: a pot body 10, a heat preservation cover 20, an inner pot 30 and a cover body 50. Wherein, the heat preservation cover 20 is arranged in the cooker body 10; the inner pot 30 is arranged in the heat-insulating cover 20, and a plurality of pot teeth 40 extending outwards are arranged at the opening part of the heat-insulating cover 20 or the inner pot 30; the lid body 50 is covered on the pot body 10, a plurality of lid teeth 521 extending inwards are arranged at the bottom of the lid body 50, the plurality of lid teeth 521 are matched with the plurality of pot teeth 40, and a convex part 522 protruding towards the inside of the lid body 50 is connected to one end of at least one lid tooth 521.

By applying the technical scheme of the embodiment, the plurality of pot teeth 40 extending outwards are arranged at the opening part of the heat-insulating cover 20 or the inner pot 30, the plurality of cover teeth 521 extending inwards are arranged at the bottom part of the cover body 50, and the pressure-bearing requirement in the cooking process can be met when the pot teeth 40 and the cover teeth 521 are buckled. Different from the cover teeth in the related art, in the embodiment, one end of at least one cover tooth 521 is connected to a protrusion 522 protruding toward the inside of the cover 50, so that the cover tooth 521 is not suspended, and the end of the cover tooth 521 corresponding to the protrusion 522 is connected to the cover 50 through the protrusion 522, so that the cover tooth 521 is not easily deformed. When the cooker is pressed upward, the force acting on the lid teeth 521 can be transmitted to the protrusion 522 and the lid 50, so that the pressure-receiving capacity of the lid 50 can be enhanced. Thus, the cover 50 of the present application can be made thinner to meet the same pressure requirement, resulting in lower cost. Therefore, the technical scheme of the application can effectively solve the problem that the cover body is thick to meet the requirement of the cover tooth strength in the related art, so that the cost is high.

The number of pot teeth and lid teeth is between two and ten. In the present exemplary embodiment, the number of lid teeth 521 and pot teeth 40 is six.

As shown in fig. 2, 3, 6 and 7, the convex portion 522 is plural, and one convex portion 522 is provided at the same end of each of the cap teeth 521. As shown in fig. 2, the "same end" specifically refers to: in the present embodiment, for each set of the cover teeth 521 and the protrusions 522 connected to each other, the protrusions 522 are located on the same side (e.g., the right side in fig. 2) of the cover teeth 521. This arrangement makes it possible to more uniformly apply a force to the lid body 50 when pressure is applied.

As shown in fig. 2 and 3, the cover body 50 includes a cover top plate 523 and a side plate 524 disposed at an edge of the cover top plate 523, the cover teeth 521 are disposed at a bottom portion of the side plate 524, the protrusions 522 are disposed on the side plate 524, and a bottom end of the protrusions 522 extends to a bottom surface of the side plate 524. Specifically, in the present embodiment, the protrusion 522 is formed by stamping the side plate 524, the bottom end of the protrusion 522 extends to the bottom surface of the side plate 524, and the end of the cover tooth 521 corresponding to the protrusion 522 achieves a smooth transition with the bottom surface of the side plate 524 through the protrusion 522, so that the cover 50 is easy to process and more beautiful. The other end of the cover teeth 521 is directly connected to the side plate 524.

As shown in fig. 7, in the present embodiment, the convex portion 522 protrudes from the cover tooth 521 toward the inside of the cover 50. Therefore, the connection size of the connection end of the cover tooth 521 and the convex part 522 and the side wall of the convex part 522 is ensured to be as large as possible, and the pressure bearing capacity of the cover tooth 521 can be further ensured. Of course, in other possible embodiments, the projection may be flush with the cover tooth toward the inside of the cover body.

As shown in fig. 4 to 7, in the present embodiment, the pot teeth 40 are provided on the heat retaining cover 20, and the distance a1 between the convex portion 522 and the center of the lid body 50 is larger than the radius R1 of the tooth bottom surface 41 of the pot teeth 40. Thus, when the lid 50 is placed over the pot body 10, the projections 522 do not interfere with the tooth bottom surfaces 41 of the pot teeth 40.

Specifically, the difference between the distance a1 and the radius R1 of the bottom tooth surface 41 of the pot tooth 40 satisfies: A1-R1 is more than or equal to 0.5mm and less than or equal to 5 mm. When the A1-R1 is less than 0.5mm, the cover is inconvenient to close because of manufacturing errors and the difficulty of completely aligning the cover body 50 with the heat-preserving cover 20 when the cover is closed by a user. When a1-R1 is greater than 5mm, the distance between the bottom tooth surface 41 and the edge of the cover tooth 521 is too large, so that in order to ensure the overlapping area (i.e. the pressure-bearing area when the pot is pressed upwards) when the cover tooth 521 and the pot tooth 40 are buckled, the top tooth surface 42 of the pot tooth 40 needs to protrude a longer distance to the outer side of the heat-insulating cover 20 than the bottom tooth surface 41, which increases the material used for manufacturing the heat-insulating cover 20, and simultaneously, the moment when the pot tooth 40 bears pressure is large, and the pressure-bearing effect is not good. Preferably, A1-R1 may be 2mm, 3mm or 4 mm.

As shown in fig. 4 to 7, in the present embodiment, the distance a1 is smaller than the radius R2 of the crest face 42 of the pot tooth 40, and the difference between the radius R2 of the crest face 42 of the pot tooth 40 and the distance a1 satisfies: R2-A1 is more than or equal to 2.5 and less than or equal to 7.5. Therefore, when the cover body 50 is rotated to enable the pot teeth 40 and the cover teeth 521 to be buckled together, the convex portion 522 can form a stop for the pot teeth 40, so that the pressure bearing capacity of the cover body 50 is enhanced by the arrangement of the convex portion 522, the stop effect can be achieved, and no additional stop structure is needed. Preferably, R2-A1 may be 4mm, 5mm or 6 mm.

As shown in fig. 6 and 7, the bottom surface of the protrusion 522 is provided with a notch 5221. In this embodiment, the cover teeth 521 and the protrusions 522 are formed by pressing the cover 50, and the material at the connecting position of the cover teeth 521 and the protrusions 522, where the material is accumulated during the pressing process, is removed by machining the notches 5221 on the bottom surface of the protrusions 522, so that the material at the connecting position of the accumulated cover teeth 521 and the protrusions 522 can be removed, and the cover 50 is more beautiful.

As shown in fig. 6 and 7, the plurality of cover teeth 521 are uniformly arranged along the circumferential direction of the cover body 50, the pot teeth 40 are provided at the mouth of the heat-insulating cover 20, and the pot teeth 40 are uniformly arranged along the circumferential direction of the heat-insulating cover 20. Thus, the stress applied when the lid tooth 521 and the pot tooth 40 are pressed can be uniformly distributed along the circumferential direction of the lid body 50 and the heat insulating cover 20.

As shown in fig. 1, in the present embodiment, the cover body 50 includes an outer cover 51 and a metal inner cover 52 disposed inside the outer cover 51, and a plurality of cover teeth 521 are disposed on the metal inner cover 52; the cooking appliance further includes a packing 60 disposed between the cover 50 and the inner pot 30, and a heat generating plate 70 disposed at the bottom of the inner pot 30. The metal inner cover 52 can meet the pressure-bearing requirement in the pressure cooking process, the sealing ring 60 can realize the sealing between the inner pot 30 and the metal inner cover 52, and the cover body 50, the inner pot 30 and the sealing ring 60 form a sealed cavity to ensure the cooking effect.
