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 and 7, the cooking appliance of the present embodiment includes: the pot comprises a pot body 10, a cover body 20, a locking structure and a curling structure 30, wherein the cover body 20 is covered on the pot body 10. The locking structure is arranged between the cover body 20 and the pot body 10. The locking structure comprises a first thread 13 arranged on the pot body 10 and a second thread 21 arranged on the cover body 20, wherein the second thread 21 is matched with the first thread 13. The curling structure 30 is arranged at the pot mouth of the pot body 10.

By applying the technical scheme of the embodiment, the first thread 13 and the second thread 21 are matched to realize the locking of the pot body 10 and the cover body 20, and the safety of the cooking appliance in an up-pressing state can be ensured. The arrangement of the thread fit can well give consideration to the locking effect and the processing cost, and meanwhile, the cooking utensil is reasonable in size. The thread processing has the characteristics of simple process, low cost and good locking effect. Meanwhile, compared with the flanging and thread-buckling process in the related technology, the thread processing does not need to cut off a large amount of materials to form spaced gaps so as to realize the matching of the pot body and the cover body, so that the process is simple, and the connection strength is higher. Therefore, the technical scheme of the embodiment effectively solves the problem of complex locking structure process in the related art. Meanwhile, as the curling structure 30 is arranged at the pot opening of the pot body 10, the deformation resistance strength of the pot opening can be increased, so that the pot opening is not easy to deform and the roundness of the pot opening is ensured. Thus, the cover 20 is easily covered on the pot 10 by the cooperation of the second screw 21 and the first screw 13.

In the present embodiment, as shown in fig. 5 and 7, the second thread 21 is an internal thread, the first thread 13 is an external thread, and the crimping structure 30 is located above the first thread 13. Of course, in other embodiments not shown in the figures, the second thread may be an external thread and the first thread may be an internal thread.

As shown in fig. 4, in order to further improve the strength of the pot mouth against deformation, the outer side surface of the crimping structure 30 includes a first arc surface. Meanwhile, the arrangement of the curling structure 30 of the first cambered surface can improve the holding feeling on one hand and has better appearance on the other hand.

Of course, in other embodiments not shown in the figures, the outer side of the crimping structure may include a first arc and a flat surface. The outer side of the hemming structure may also comprise only a plane.

As shown in fig. 4 and 7, in order to enable the longitudinal section of the hemming structure 30 to be rolled up to be close to a circular shape, the inner side of the hemming structure 30 includes a second arc surface having a radius r1 greater than the thickness of the hemming structure 30. Thus, the hemming structure 30 is made beautiful.

Of course, in other embodiments not shown in the figures, the radius r1 of the second arc is equal to the thickness of the hem structure.

As shown in fig. 4 and 7, in order to make the longitudinal section of the hemming structure 30 more capable of being rolled up to be close to a circular shape, the dimension h of the hemming structure 30 in the vertical direction satisfies: h is more than or equal to 4mm and less than or equal to 10 mm. Thus, the curling structure 30 is more beautiful. Preferably, the dimension h of the hemming structure 30 in the vertical direction may be 4mm or 6mm or 8mm or 10 mm.

As shown in fig. 3 and 4, in the process of matching the second thread 21 with the first thread 13, in order to enable the second thread 21 on the lid body 20 to smoothly pass through the hemming structure 30 and avoid interference with the hemming structure 30, the outside diameter of the hemming structure 30 is smaller than the outside diameter of the pot body 10.

Of course, in other embodiments not shown in the figures, the outside diameter of the crimping structure is equal to the outside diameter of the pan body.

As shown in fig. 3 and 4, the crimping structure 30 includes a straight section 31 and a crimped section 32 connected to the straight section 31. Straight section 31 extends toward the center of pan body 10. Thus, the above-mentioned structure of the turned edge structure 30 makes the pot opening of the pot body 10 have higher structural strength on one hand, and makes the pot opening of the pot body 10 more beautiful on the other hand.

In the present application, since the second thread is more pressure-bearing than the locking structure in the related art in cooperation with the first thread, the thickness of the material can be reduced. The material of the pot body adopts SUS304(304 stainless steel), the thickness of the pot body which does not use the screw thread screwing mode is between 1.0 and 1.5mm, and after the screw thread screwing mode is used, the material thickness of the pot body is reduced, the thickness of the pot body is between 0.8 and 1.2mm, the thickness of the pot body is thinned, the pot opening of the pot body is easy to deform relatively, and the cover body is difficult to cover on the pot body.

In order to solve the problem that the pot opening of the pot body is relatively easy to deform, as shown in fig. 2 and 3, in the embodiment, a curling structure 30 is arranged at the pot opening of the pot body 10, so that the deformation resistance strength of the pot opening is enhanced, and the thickness of the pot body 10 can be set within the range of 0.8mm to 1.2 mm. Thus, the thickness of the pot body 10 is reduced and the processing cost of the pot body can be reduced.

As shown in fig. 3 and 4, in order to further ensure that the pot mouth of the pot body 10 has high structural strength. The included angle a formed between the side wall of the pot body 10 and the straight section 31 satisfies the following conditions: a is more than or equal to 110 degrees and less than or equal to 145 degrees. Meanwhile, the included angle a satisfies: a is more than or equal to 110 degrees and less than or equal to 145 degrees, so that the pot mouth of the pot body 10 is easy to process, and the process is simple. The angle a formed between the side wall of pan body 10 and straight section 31 may be 110 ° or 120 ° or 130 ° or 140 ° or 145 °.

The connecting portion 41 is provided on the inner side of the lid body 20, and the lip portion 42 extends to the inner side of the hemming structure 30. In order to ensure that the lower part of the tangent point between the lip part 42 and the inner side of the curling structure 30 does not stick to the pot opening before the upward pressure is applied in the cooking utensil, when the cover body 20 is opened and closed, the friction between the lip part 42 and the pot opening is reduced, and the cover body 20 is smoothly opened and closed. The lip portion 42 includes a first connecting section 421 and a second connecting section 422, and an included angle b is formed between the first connecting section 421 and the second connecting section 422, and is greater than or equal to the included angle a. Thus, the contact area between the lip portion 42 and the inside of the hemming structure 30 is reduced, and the frictional resistance when the lid body 20 is opened and closed is reduced, so that the lid body 20 is easily opened and closed.

Preferably, the interference of the lip portion 42 with the crimping structure 30 is in the range of 0.2mm-0.5 mm.

As shown in fig. 6 and 7, in order to ensure the sealing effect of the gasket 40 and reduce the friction between the lip portion 42 and the pot mouth, the lid body 20 is smoothly opened and closed. The seal ring 40 includes a lip portion 42, the lip portion 42 projecting downwardly into the bead structure 30 a distance d that satisfies: d is more than or equal to 5mm and less than or equal to 12 mm.
