This creation is related to the structure of pressure cookers, especially pressure cookers with elastic deformation structures.

The pressure cookers currently on the market generally include parts such as pot body, lid, sealing ring, inner pot, outer pot, heating plate, pressure switch, and temperature controller. Most of them use a pad or elastic material between the heating plate and the outer pot to provide elastic deformation to ensure that the inner pot and the heating plate can move downward when there is pressure in the pressure cooker. Through the pins on the heating plate or the elastic outer The bottom surface of the pot drives the pressure switch to work on and off, thereby ensuring the safety performance of the pressure cooker. However, this method will undoubtedly increase the cost of the product, and the assembly process is complicated, which increases the cost of man-hours.

During the use process, the product has certain requirements in terms of response to hot and cold shock, durability and dry-burning durability. If the parameters of the product are not designed properly, the composite bottom will easily fall off, blister, abnormal noise, etc. during use. Significant changes in radian and other conditions that affect performance.

Furthermore, the pot body of the existing pressure cooker cannot be used well on the induction cooker because the bottom of the pot body is heated to produce a bulge or the bottom is irreversibly deformed and other adverse effects.

In view of the above shortcomings, the creator researched ways to improve these shortcomings, and finally came up with this creation.

Please refer to Figures 1 and 2, together with Figures 3 and 8, which are cross-sectional views, partially enlarged views and perspective views of the first embodiment of the invention, which discloses a pressure cooker 100 with an elastic deformation structure 131. and contains:

A pot body 10 has a pot mouth 11, a pot wall 12 and a pot bottom 13. The pot bottom 13 is connected to the pot wall 12, and the pot wall 12 is surrounded by a pot mouth 11. The pot bottom 13 is provided with at least one elastic deformation structure. 131. The elastic deformation structure 131 includes:

At least one planar deformation portion 1311 is located at the center of the pot bottom 13. The planar deformation portion 1311 is selected from a circular plane or a polygonal plane. In this embodiment, a circular plane is used as an example for the planar deformation portion 1311.

There are at least two first bending deformation parts 1312. The first bending deformation parts 1312 are in an arc-shaped shape and are configured to be connected to the pot bottom 13 along the outer periphery of the planar deformation part 1311.

At least two second bending deformation parts 1313, the second bending deformation part 1313 is smaller than the first bending deformation part 1312; the second bending deformation part 1313 is in an arc shape and is configured to be connected to the pot bottom 13 along the outer periphery of the planar deformation part 1311. ; Furthermore, the first bending deformation portion 1312 and the second bending deformation portion 1313 are connected to form an S-shaped structure.

In this embodiment, the plane deformation part 1311 is separated from the bottom surface of the pot bottom 13 by a distance, and the plane deformation part 1311 is disposed on the bottom surface of the pot bottom 13 by connecting the first bending deformation part 1312 and the second bending deformation part 1313, so that the pot bottom The central position of 13 has an elastic deformation structure 131 that is convex inside and concave outside.

In this embodiment, the bending arc of the first bending deformation part 1312 is 1 to 1.5 times greater than that of the second bending deformation part 1313 , that is, the first bending deformation part 1312 has more space for thermal deformation than the second bending deformation part 1313 .

It should be further explained that the elastic deformation structure 131 is integrally formed with the pot bottom 13, and the pot body 10 is used to combine a pot lid 20 with a pressure relief valve 21, and the pot lid 20 is connected to a handle 30; in addition, the elastic deformation structure The recessed depth of 131 relative to the pot bottom 13 is 1 mm to 20 mm; the recessed depth of the elastic deformation structure 131 relative to the pot bottom 13 is greater than 3 mm. The inner convex surface constructed by the elastic deformation structure 131 in the pot guides the heat flow in the pot and improves the uniformity of heat distribution in the pot.

In order to further understand the structural characteristics of this creation, the application of technical means and the expected effects, the usage of this creation is described here. I believe that this will lead to a more in-depth and specific understanding of this creation, as follows:

Please continue to refer to Figure 8, and as shown in Figures 1, 2 and 3, the present invention mainly utilizes the design of the pot bottom 13 to have a structure in which the bottom is recessed into the pot as a whole, and through the arrangement of the elastic deformation structure 131, this can prevent In the case of dry burning or hot and cold shock, the bottom 13 of the pot will be irreversibly deformed outwardly to protrude from the bottom plane of the pot to ensure the stability of the elastically deformed concave structure and avoid the occurrence of metal gaps during high-temperature heating. The expansion tension causes adverse effects such as bulging or irreversible deformation of the bottom, reducing the risk of pot defects and improving the quality of the pot.

It can be further understood from the above that when the pot body 10 is placed on the induction cooker for heating, since the second bending deformation portion 1313 in the elastic deformation structure 131 is smaller than the first bending deformation portion 1312, the first bending deformation portion 1312 bends The large curvature and thermal deformation will cause the planar deformation portion 1311 to locally deform and concave toward the inside of the pot body 10. At the same time, the second bending deformation portion 1313 can also provide elastic deformation, so the support strength of the pot body 10 when heated can be ensured. ; Of course, when the pot body 10 is cooled, the elastic deformation structure 131 will shrink and deform as it cools, and gradually return to its original state.

Please refer to FIG. 4 again, which is a partial enlarged view of the elastic deformation structure 131 in the second embodiment of the present invention. Compared with the first embodiment, the difference between this embodiment and the first embodiment is that the first bending deformation part 1312 and the second bending deformation part 1313 are in the shape of a rectangular concave part and are configured to be connected to the pot bottom 13 along the outer periphery of the planar deformation part 1311 , and the first bending deformation part 1312 and the second bending deformation part 1313 are connected to form an S-shaped structure; this embodiment can also achieve the same functions and effects as the above-mentioned first embodiment.

Please refer to FIG. 5 again, which is a partial enlarged view showing the elastic deformation structure 131 in the third embodiment of the present invention. Compared with the first embodiment, the difference between this embodiment and the first embodiment is that the pot bottom 13 has at least two elastic deformation structures 131, one of which is provided with another elastic deformation structure 131. It can be seen from the figure that this The two elastic deformation structures 131 of the embodiment allow the pot bottom 13 to be formed into a convex shape, and this embodiment can also achieve the same functions and effects as the first embodiment. Furthermore, because this embodiment has two elastic deformation structures 131, When in the heated state, the inner convex surface formed by the two elastic deformation structures 131 has a good conductive effect on the heat flow in the pot, which is more conducive to guiding the formation of multiple heat convection loops in the pot and improving the uniformity of heat distribution in the pot. , improve cooking effect.

Please refer to Figures 6 and 7 again. Figure 6 is a cross-sectional view and a bottom view of the fourth embodiment of the present invention. Compared with the first embodiment, the difference between this embodiment and the first embodiment is that the pot bottom 13 has a plurality of elastic deformation structures 131. The elastic deformation structures 131 are arranged around the pot bottom 13 at intervals, and there is an elastic deformation structure in the center of the pot bottom 13. 131; This embodiment can also achieve the same functions and effects as the first embodiment. Furthermore, this embodiment has a plurality of elastic deformation structures 131, so when it is heated, the inner convex surface formed by the plurality of elastic deformation structures 131 It has a good diversion effect on the heat flow in the pot, which is more conducive to guiding the formation of multiple heat convection loops of different sizes in the pot, and more efficiently improves the uniformity of heat distribution in the pot and improves the cooking effect.

Hereby, the characteristics of this creation and the expected effects it can achieve are stated as follows:

First, the second bending deformation part 1313 in the elastic deformation structure 131 of this invention is smaller than the first bending deformation part 1312, so the first bending deformation part 1312 takes a large arc and deforms when heated to ensure the elastic deformation of the concave structure. Stability, to avoid adverse effects such as bulging or irreversible deformation of the bottom due to the expansion tension between metals during high-temperature heating.

Secondly, because the invention has multiple elastic deformation structures 131, when it is heated, the inner convex surface formed by the multiple elastic deformation structures 131 has a good conductive effect on the heat flow in the pot, which is more conducive to guiding the heat flow in the pot. Multiple heat convection loops of different sizes can more efficiently improve the uniformity of heat distribution in the pot and improve the cooking effect.
