Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Thelid 100 of the pressure cooker according to the embodiment of the first aspect of the present invention is described in detail below with reference to fig. 1 to 7.
Thepressure cooker lid 100 according to the embodiment of the present invention includes anelliptical lid body 10, thelid body 10 is formed by press molding a plate material, and the inner surface of thelid body 10 has arib 20 formed integrally with thelid body 10 by press molding.
In other words, thelid 100 of the pressure cooker mainly comprises alid body 10, wherein thelid body 10 extends in a horizontal direction (left and right directions as shown in fig. 1), thelid body 10 may be formed by processing a plate material through a plurality of stamping processes, the shape of thelid body 10 obtained after the processing is substantially oval, and during the stamping process, a part of the upper surface of the plate material is recessed downward to form a plurality of grooves on the upper surface of thelid body 10, and a protrudingrib 20 protruding downward is formed on the lower surface of the lid body 10 (i.e., a side surface of thelid body 10 facing the cooker body), so as to improve the strength and rigidity of thelid body 10 of the pressure cooker. Further, a connecting portion (not shown) adapted to be connected to a pot body (not shown) of the pressure cooker is disposed on thepot cover body 10, so as to facilitate connection between thepot cover 100 and the pot body.
Moreover, theconvex rib 20 and thecooker lid body 10 are integrally formed, and the integrally formed structure not only can ensure the stability of the structure and performance of thecooker lid 100, but also is convenient to form and simple to manufacture, so that thecooker lid 100 of the pressure cooker has higher integral strength and stability, is more convenient to assemble and has longer service life.
The lid body of the pressure cooker in the related art and thelid body 10 of thelid 100 in the embodiment of the present invention are both formed in an oval shape, and both are formed by stamping a plate material with the same thickness, except that a plurality of downwardly protrudingribs 20 are stamped and formed on the lower surface of thelid body 10 of the pressure cooker in the embodiment of the present invention. Compared with the pressure cooker cover body which has the same size and is not provided with the convex rib design in the related technology, thepressure cooker cover 100 has better strength and rigidity.
Therefore, according to thepot cover 100 of the pressure cooker of the embodiment of the invention, the downward protrudingconvex rib 20 is arranged on the inner surface of thepot cover body 10 of thepot cover 100, so that the structural strength and rigidity of thepot cover 100 of the pressure cooker can be improved, the pressure bearing capacity of thepot cover 100 is improved, and the working time of the pot cover 100 under the working conditions of high temperature and high pressure is prolonged, thereby prolonging the service life of thepot cover 100.
In some embodiments of the present invention, therib 20 is in an elliptical ring shape, and the shape of therib 20 is adapted to the shape of thelid body 10. That is, an elliptical ring-shaped rib 20 is provided on the inner surface (the side surface facing the pot body) of the ellipticalpot cover body 10, and the elliptical ring-shaped rib 20 protrudes from the lower surface of thepot cover body 10. Preferably, the center of the elliptical ring-shaped rib 20 coincides with the center of thepot lid body 10. Therefore, the ellipticalannular convex rib 20 is arranged on thecooker cover body 10, so that the structural strength or rigidity of thecooker cover 100 of the pressure cooker is improved, the pressure bearing capacity of thecooker cover 100 is improved, and the service life of thecooker cover 100 of the pressure cooker is prolonged.
In other embodiments of the present invention, the plurality ofribs 20 are included, and eachrib 20 extends along the short axis direction of thelid body 10 and is distributed along the long axis direction of thelid body 10.
In other words, the lower surface of thelid body 10 is provided with a plurality ofribs 20 spaced apart in the length direction (front-rear direction as shown in fig. 1) of thelid body 10, and eachrib 20 may extend in the width direction (left-right direction as shown in fig. 1) of thelid body 10. The plurality ofribs 20 are orderly arranged on thepot cover body 10, which can improve the strength and rigidity of thepot cover 100, thereby improving the lifespan of thecover 100 of the pressure cooker. Another scheme for arranging a plurality ofconvex ribs 20 on thepot cover body 10 is as follows: the inner surface of the cooker cover body is provided with a plurality of convex ribs which extend along the length direction and are distributed along the width direction. Compared with the technical scheme of arranging the convex ribs, in the technical scheme of arranging theconvex ribs 20 provided by the embodiment, the length of theconvex ribs 20 is shorter, so that the warping strength is relatively higher, and the strength of thepot cover body 10 can be better improved.
Preferably, according to an embodiment of the present invention, at least one of theribs 20 passes through the short axis of thelid body 10. Specifically, one of theribs 20 is located in the middle of thepot lid body 10, and theother ribs 20 are symmetrically arranged with respect to the symmetry axis of thepot lid body 10 in the length direction. Therefore, by arranging the plurality of symmetrically arrangedconvex ribs 20 on thecooker cover body 10, the structural strength and rigidity of thecooker cover 100 of the pressure cooker can be improved, so that the service life of thecooker cover 100 is prolonged, the appearance attractiveness of thecooker cover 100 can be improved, and aesthetic feeling experience is visually brought to people. It should be noted that, in the embodiment, at least one of theribs 20 passes through the short axis of thepot lid body 10, which includes not only the case that therib 20 completely coincides with the short axis of thepot lid body 10, but also the case that therib 20 partially coincides with the short axis of thepot lid body 10, but generally, the rib passes through the middle of the short axis of thepot lid body 10, i.e. the center of thepot lid body 10. This rib passing through the short axis of thelid body 10 is very effective for enhancing the strength of the central region of thelid body 10.
Advantageously, the extending length of therib 20 is gradually reduced from the center of thelid body 10 to the long axis end of thelid body 10. That is to say that the position of the first electrode, the length of theconvex rib 20 positioned in the middle of thepot cover body 10 is greater than the length of theconvex ribs 20 positioned at both sides. The shape and length of therib 20 are matched with the shape and size of thecooker cover body 10, so as to improve the structural strength, rigidity and appearance aesthetic property of thecooker cover 100 of the pressure cooker.
For example, as shown in fig. 1, in the present embodiment, theribs 20 include threeribs 20, and theribs 20 are all linear. Wherein, the linear length of the convex linear rib passing through the short shaft on the pot cover body 10 (i.e. theconvex rib 20 positioned in the middle of the pot cover body 10) is greater than the linear length of the linearconvex ribs 20 positioned on both sides.
Alternatively, theribs 20 are all arc-shaped, and the bending directions of theribs 20 are all the same. Specifically, as shown in fig. 3, the lower surface of thelid body 10 is provided with threeribs 20 arranged at intervals in the length direction thereof (the front-rear direction shown in fig. 3), eachrib 20 is formed in a circular arc shape, and eachrib 20 is symmetrically arranged with respect to the symmetry axis of thelid body 10 in the width direction (the left-right direction shown in fig. 3). Wherein the bending radius of theconvex rib 20 ranges from 100mm to 125mm. Therefore, the circular arc-shapedconvex rib 20 is arranged on thepot cover body 10, which is beneficial to improving the rigidity of thepot cover 100.
In a specific example of the present invention, the oval-shapedpot lid body 10 has a length b of 350mm to 360mm, a width a of 265mm to 275mm, and a thickness c of 2mm to 3mm. The number of theribs 20 on the lower surface of thepot cover body 10 is three, and eachrib 20 is symmetrically arranged relative to the symmetry axis of thepot cover body 10 in the length direction. Alternatively, the linear distance L1 between both ends of eachrib 20 is 150mm to 170mm, the width L2 is 27mm to 30mm, and the height L3 of eachrib 20 protruding downward (i.e., the depth of each groove recessed downward) is 2mm to 3mm.
For thepot cover 100 within the size range, the downward protrudingribs 20 are arranged on the lower surface of thepot cover body 10, so that the structural strength and rigidity of thepot cover 100 of the pressure cooker can be improved, the bearing capacity of thepot cover 100 is improved, the working time of thepot cover 100 under the working conditions of high temperature and high pressure is prolonged, and the service life of thepot cover 100 is prolonged.
