Problems solved by technology

[0004] In order to solve the problems of low utilization rate of pot lid material, high cost and difficulty in taking into account food hygiene and material strength due to ignoring the difference in stress in the prior art, the present invention proposes a technical solution for a composite pressure cooker lid, which includes a center Cap and capping ring; the capping ring is a ring structure, which includes the inner side of the capping ring and the outer side of the capping ring, the inner side of the capping ring is fixedly connected with the outer edge of the center cap, and a connecting mechanism is set outside the capping ring

Embodiment 1

[0016] Embodiment 1 Referring to Fig. 1, take the inner pot diameter of 22cm and the maximum working pressure of 100kPa as an example: the center cover 1 is made of high-quality, corrosion-resistant, stainless steel plate that meets food hygiene requirements, such as SUS304, etc., and its thickness can be determined according to the diameter of the inner pot. The size, that is, the size of the force is determined. When the caliber of the inner pot is 22cm, a material with a thickness of about 0.6mm can be selected for use. Compared with the thickness of about 1.2 mm commonly used in the prior art, the space for material saving is large. In order to make the center cover 1 have a better force bearing capacity, it can be designed as an upper convex circle. The outer edge 3 of the center cover is turned inward to form a hanging ring, which can meet the needs of hanging the sealing ring, so that the hanging ring in the prior art can be omitted, and the purpose of saving materials...

Embodiment 2

[0020] Embodiment 2 is referring to Fig. 2, is the embodiment of elastic composite pressure cooker cover. Still taking the inner diameter of the pot of 22cm and the maximum working pressure of 100kPa as an example: the transition part between the outer side 5 of the lid ring and the inner side 4 of the lid ring is designed as a circular arc transition 6 according to the requirements of the elastic composite pressure cooker lid. The transition 6 is the part that produces elastic deformation after being stressed, that is, the arc transition 6 between the maximum diameter of the capping ring 2 and its minimum diameter. The R dimension of the circular arc transition 6 in Fig. 2 can be selected at about 16mm, in order to obtain enough elastic displacement, can select the radius difference between the inner side 4 of the appropriate denture ring and the outer side 5 of the denture ring, this difference and the elasticity The amount of displacement is proportional, and the radius dif...

Abstract

The present invention discloses one technological scheme for composite pressure cooker cover, and belongs to the field of cooker technology. The composite pressure cooker cover includes one central cover and one toothed ring, and the toothed ring includes one inside ring connected to the central cover and one outer ring with a connecting mechanism. The present invention has the cooker cover stress considered, and possesses high material utilization and lowered production cost.

Description

Technical field: [0001] The invention belongs to kitchen utensils, and is a pressure electric rice cooker, an electric pressure cooker, and a pot cover part of a pressure cooker. Background technique: [0002] Existing pressure electric rice cooker, electric pressure cooker, pressure cooker product, its pot cover adopts stamping, stretching process molding by a whole piece of steel plate, is called integral pot cover here. When making the whole pot cover, the square plate is first processed into a circular plate, and then stretched and trimmed. Because the utilization rate of the material is less than two-thirds, the material cost is very high. From the perspective of the force characteristics of the pot cover, the stress that the cover tooth part of the pot cover bears during work is very different from that of other parts of the pot cover. In the strength design of the whole pot cover, only The thickness dimension of the whole steel plate is determined by the maximum stre...
