Specifically, the upper liner 1 may be supported at the rim 21 of the inner pot 2, or a boss may be disposed on an inner wall surface of a side wall of the inner pot 2, so that the upper liner 1 is supported on the boss, and the supporting positions of the upper liner 1 on the inner pot 2 are different, resulting in different supporting structures disposed on the upper liner 1.
In some embodiments of the present invention, as shown in fig. 1 and 4, the minimum vertical distance H from the maximum latitude circle of the side wall 12 of the container body 10 to the bottom wall 11 of the container body 10 and the minimum vertical distance H from the throat formed at the mouth of the container body 10 to the bottom wall 11 of the container body 10 satisfy 1/4 ≦ H/H ≦ 4/5.
The H/H is used for limiting whether the maximum latitude circle position of the side wall 12 of the container body 10 (namely the maximum expansion position of the container body 10 during processing) is located at an upper position or a lower position, and the maximum latitude circle position of the side wall 12 of the container body 10 is designed to be located at the position 1/4-4/5 of the height of the container body 10 so as to ensure that liquid food in the upper inner container 1 has a strong heat convection effect and ensure that the upper inner container 1 has a reasonable overall dimension, thereby avoiding the problems that the maximum latitude circle position of the side wall 12 of the container body 10 is too upper or too lower to cause the design of the upper inner container 1 to be inconsistent, the processing is difficult, the assembly with the inner pot 2 is difficult and the like.
In some embodiments of the present invention, as shown in fig. 1 to 3 and 10 to 12, the sidewall 12 of the bladder 10 is a circular sidewall, and the circular sidewall is connected to the bottom wall 11 of the bladder 10 to form a spherical bladder.
The side wall 12 of the liner body 10 is designed to be an arc side wall, the arc side wall is connected with the bottom wall 11 of the liner body 10 to form a spherical liner body, the arc forming of the side wall 12 of the liner body 10 is smooth, liquid food in the upper liner 1 can easily generate convection along the arc surface, and therefore the food in the upper liner 1 can be heated more uniformly.
Preferably, as shown in fig. 1 and 2, the minimum vertical distance H from the maximum latitude circle of the side wall 12 of the container body 10 to the bottom wall 11 of the container body 10 and the minimum vertical distance H from the necking formed at the mouth of the container body 10 to the bottom wall 11 of the container body 10 satisfy 1/2 ≦ H/H ≦ 4/5; the reference h1 in fig. 2 indicates the vertical distance between the maximum latitude circle of the side wall 12 of the container body 10 and the lower surface of the step surface 13.
The vertical dashed lines in fig. 2 indicate the central axis of the upper liner 1, and the two dashed circles in fig. 2 indicate the circles of the inner wall surfaces of the arc-shaped sidewalls of the liner body 10, and the two dashed circles in the drawing may or may not intersect, may be tangent to, and preferably intersect.
For a spherical liner, the maximum latitude circle of the side wall 12 of the liner body 10 is designed to be located at the position 1/2-4/5 of the height of the liner body 10, so that the problem that the liner mouth of the liner body 10 is seriously shrunk due to too low maximum latitude circle of the side wall 12 of the liner body 10 and food materials in the liner 1 are not easy to take and place is avoided.
Optionally, the bottom wall 11 of the container body 10 is a flat surface or a concave surface which is concave upward or a convex surface which is convex downward.
The bottom wall 11 of the liner body 10 can be a plane, so that the liner body 10 is convenient to process; the bottom wall 11 of the liner body 10 can also be a concave surface which is concave upwards or a convex surface which is convex downwards, so that the heated area at the bottom of the liner body 10 is increased, and the heating efficiency is improved.
In one embodiment, as shown in fig. 2, the bottom wall 11 of the container body 10 is a circular plane, and the circular arc sidewall is smoothly transited and connected to the circular plane and is tangent to the circular plane.
The circular arc lateral wall of the design courage body 10 is tangent with circular plane, thereby make circular arc lateral wall and circular plane's junction smooth transition connect, such design makes liquid food more smooth and easy when flowing along the wall of the courage body 10, thereby be convenient for the continuous convection current of liquid food in the last inner bag 1 rolls, promote the homogeneity of food heating in the inner bag 1, and the steam of being convenient for produce in the inner pan 2 smoothly enters into and heats the food in last inner bag 1 in the inner bag 1, improve the heating efficiency of food in last inner bag 1.
Preferably, as shown in FIG. 2, the diameter D of the circular plane satisfies 0. ltoreq. D.ltoreq.150 mm.
Of course, the diameter of the circular plane formed by the bottom wall 11 of the container body 10 can be adjusted as appropriate for cooking devices of different sizes.
In one embodiment of the present invention, as shown in fig. 3, the side wall 12 of the container body 10 includes an upper circular-arc side wall section 121, a lower circular-arc side wall section 123, and a transition section 122 connecting the upper circular-arc side wall section 121 and the lower circular-arc side wall section 123, the transition section 122 being outwardly offset with respect to the lower circular-arc side wall section 123, and the largest latitude circle of the container body 10 being located at the upper circular-arc side wall section 121.
The transition section 122 is connected between the upper arc side wall section 121 and the lower arc side wall section 123 of the liner body 10, and the transition section 122 is outwardly offset relative to the lower arc side wall section 123, so that the liquid food flowing close to the inner wall of the liner body 10 is collided by the liquid food with a certain distance from the inner wall of the transition section 122, and the liquid food close to the inner wall of the liner body 10 is caused to continuously cling to the inner wall of the liner body 10 at the upper arc side wall section 121 to flow, thereby driving the liquid food in the low-temperature region of the upper arc side wall section 121 to flow, and improving the heating uniformity of the upper liner 1.
In other embodiments of the present invention, as shown in fig. 4, the side wall 12 of the container body 10 includes a circular arc-shaped side wall section 124, and an inclined side wall section 125 connected to an upper portion of the circular arc-shaped side wall section 124 and tapered toward the mouth of the container body 10, and the maximum latitude circle of the container body 10 is located at the circular arc-shaped side wall section 124.
