Above-below direction is moved, that is, makes movement of the interior pot 1 with annular support member about 4.Preferably, multiple shell fragments 6 can edge
The circumference of outer pot 2 is evenly spaced to turn up the soil and is located in outer pot 2 and positioned at the bottom of outer pot 2, and thus the support of annular support member 4 is more
Stablize and evenly, prevent annular support member 4 from inclining.
As depicted in figs. 1 and 2, the lower end of outer pot 2 has the flange 21 for extending internally, it may also be said to the lower edge tool of outer pot 2
The flange 21 that the center of oriented outer pot 2 extends, flange 21 is provided with and correspond with shell fragment 6 and the elastic deformation for shell fragment 6 is provided
Avoid the avoidance recess 22 in space 222.
That is, it is multiple to avoid recess 22, shell fragment 6 is multiple, and avoids the number of recess 22 and the number of shell fragment 6
It is equal, and a shell fragment 6 is corresponding with an avoidance recess 22, i.e., when shell fragment 6 occurs elastic deformation, avoidance recess 22 is shell fragment 6
Elastic deformation provide avoid space 222 so that annular support member 4 can successfully be realized moving up and down by shell fragment 6.
Further, as shown in figure 9, flange 21 is provided with the radial dimension (for example, in Fig. 9 of the part for avoiding recess 22
W2) more than flange 21 remainder radial dimension (for example, the W1 in Fig. 9), that is to say, that as shown in figure 9, W2 ＞
W1, thus further improves the structural strength of flange 21, so as to be conducive to supporting annular support member 4.
Advantageously, as shown in Fig. 1-Fig. 7 and Fig. 9, the interior edge of flange 21 has upwardly extending flanging 211, thus, flange
21 structural strength is further lifted, so as to be conducive to supporting annular support member 4.Flanging 211 may be integrally formed with flange 21.
In such as some embodiments of Fig. 1-Fig. 3, recess 22 is avoided by from the protuberance 221 protruding upward of flange 21 and turning over
The upper surface on side 21 limits, and shell fragment 6 is supported on protuberance 221, because protuberance 221 is protruding upward, thus will not
Increase the height of outer pot 2, so as to save material, low cost of manufacture, and make the small volume of pressure cooker 100, be easy to place.Favorably
Ground, protuberance 221 and flange 21 can punching press or casting together, so as to the structural strength of outer pot 2 is higher.
Certainly, avoid recess 22 and be not limited to this, for example, in other embodiments of the present invention, avoiding recess 22 can
Think by by a part for flange 21 to concave into escape groove (not shown), shell fragment 6 is covered in escape groove.Specifically
For, escape groove is integrally formed with flange 21, and shell fragment 6 can be supported on the upper surface of the flange 21 of escape groove both sides.
Thus, processing technology is simple, low cost of manufacture.
Further, as shown in figure 3, the upper end of bolt 71 sequentially passes through from bottom to top flange 21 and the screw threads for fastening of shell fragment 6
To on support column 42, spring 72 is set on bolt 71, and spring 72 is located between the head of the lower end of bolt 71 and flange 21,
Thus when moving upwards under annular support member 4 drives in the elastic force that the elastic deformation of shell fragment 6 is produced, spring 72 is compressed, from
And producing certain damping force, it is to avoid annular support member 4 is moved upwards too quickly, makes the stable movement of annular support member 4, it is to avoid produced
Raw abnormal sound and crooked.Specifically, as shown in figures 1 and 3, bolt 71 includes that stud 711 and screw thread coordinate on stud 711
Nut 712, the wherein head of the lower end of bolt 71 namely refer to nut 712, and spring 72 is set on stud 711, and are located at
Between nut 712 and flange 21.
From the above description it can be seen that pressure cooker 100 according to embodiments of the present invention, will by arranging annular support member 4
Interior pot 1 is kept apart with coil panel 3, and by annular support member 4 more stably support in pot 1, make pressure cooker 100 security and
Stability is further lifted.
In addition, as depicted in figs. 1 and 2, pressure cooker 100 includes upper lid 101 and sealing ring 102, and upper lid 101 is located at outer pot 2
It is upper, sealing ring 102 is located between lid 101 and the upper edge of interior pot 1, so as to seal what is limited between interior pot 1 and upper lid 101
Cooking space, prevents pressure cooker 100 from losing heart.
