For example, the lid body 20 is pivotally connected to the pot body 10. The pot body 10 may be constructed in a rounded rectangular parallelepiped shape or any other suitable shape. The cooker body 10 is provided with an inner container 30 therein. As shown in fig. 4, the pot body 10 is provided with a housing cavity 11, and the inner pot 30 is removably provided in the housing cavity 11. As shown in fig. 3, the inner bladder 30 includes a bottom wall 32 and a side wall 33 extending upwardly from an edge of the bottom wall 32. The bottom wall 32 and the side wall 33 enclose a containing cavity 31 for containing food materials.

As shown in fig. 4, the pot body 10 is further provided therein with a heating means 70, a control means (not shown) and a temperature sensing assembly 80. The heating device 70 is disposed below the receiving cavity 11 and below the inner container 30 to heat the food in the inner container 30. The Control device may be, for example, a Micro Control Unit (MCU) for implementing cooking Control of the cooking appliance 100. The temperature sensing assembly 80 is used for detecting the temperature of the inner container 30, and may be disposed at the center of the bottom of the accommodating cavity 11 or at the side of the accommodating cavity 11. A top temperature measuring member (not shown) for detecting the temperature inside the containing chamber 31 may be further provided on the cover body 20. The heating device 70, the temperature sensing assembly 80 and the top temperature measuring member are electrically connected to the control device. The temperature sensing part feeds back the sensed temperature to the control device, so that the control device can achieve more precise control of, for example, the heating device 70, etc., based on the temperature information.

When the inner container 30 is placed in the pot body 10, the inner container 30 is supported by the pot body 10. As shown in fig. 5, the liner 30 includes a flange 34, the flange 34 being disposed at the top of the sidewall 33 and extending radially outward. The cooking appliance 100 is configured such that, when the inner bladder 30 is placed in the pot body 10, the flange 34 contacts the opening edge of the receiving cavity 11, so that the inner bladder 30 is supported by the pot body 10.

To improve the heat-retaining effect of the inner container 30, the cooking appliance 100 is configured such that the side wall 33 of the inner container 30 does not contact the pot body 10 when the inner container 30 is placed in the pot body 10, thereby avoiding contact heat conduction from the inner container 30 to the pot body 10. Preferably, when the inner container 30 is placed in the pot body 10, the distance D between the outer surface of the side wall 33 of the inner container 30 and the inner wall of the accommodating cavity 11 is 1mm to 5mm.

Preferably, the inner container 30 is configured such that, in a vertical cross section of the inner container 30, the outer surface of the side wall 33 is in the form of a straight line. The pot body 10 is configured such that, in a vertical section of the pot body 10, the side walls of the accommodating chamber 11 are in the form of straight lines. When the inner container 30 is placed in the pot body 10, in the vertical cross section of the cooking appliance 100, the outer surface of the side wall 32 of the inner container 30 is configured as a first straight line L1, the inner wall of the accommodating cavity 11 is configured as a second straight line L2, and the included angle θ between the first straight line L1 and the second straight line L2 on the same side is less than or equal to 0.5 degree.

The inner container 30 is generally formed as an isothermal body during cooking. In this case, when the gap 13 between the inner container 30 and the pot body 10 tends to be uniform, the heat radiation of the inner container 30 to the pot body 10 also tends to be uniform at different height positions of the gap 13, so that the temperatures of the height positions in the gap 13 tend to be the same, and thus the longitudinal convection cannot be formed in the gap 13, which is beneficial to the heat preservation of the inner container 30.

It is further preferred that the side wall 33 of the inner container 30 is formed in a radially symmetrical shape, and the side wall of the accommodating chamber 11 is also formed in a radially symmetrical shape. Therefore, when the inner container 30 is placed in the pot body 10, the gap 13 between the inner container 30 and the pot body 10 tends to be uniform in the circumferential direction, and circumferential convection cannot be formed in the gap 13, which is beneficial to heat preservation of the inner container 30.

Of course, it is also possible for the inner container 30 to be of a radially symmetrical shape overall and/or for the receiving space 11 to be of a radially symmetrical shape overall.

Preferably, the inner container 30 is made of a metal material, so that the inner container 30 can quickly form an isothermal body.

Preferably, the inner container 30 is integrally configured in a radiation symmetrical shape, and in an axial section (a vertical interface passing through a central axis a of the inner container 30) of the inner container 30, an outer surface of the sidewall 33 of the inner container 30 is configured as a first straight line L1, and an included angle α between the straight line L1 and the central axis a is less than or equal to 0.5 degrees. In other words, the generatrix L1 of the inner container 30 is a straight line, and the included angle between the generatrix L1 and the central axis a is less than or equal to 0.5 degrees. In this case, the generatrix of the inner container 30 extends in the vertical direction, so that the cross sections of the inner container 30 at different heights tend to be uniform, thereby effectively increasing the internal volume of the containing chamber 31.

Preferably, the sidewall 33 of the inner container 30 is configured as a cylinder. The circular cross-section enables to further increase the internal volume of the containing chamber 31.

According to the utility model discloses a cooking utensil through the lateral wall with the inner bag with the lateral wall parallel arrangement who holds the chamber for the inner bag is even with the clearance that holds the chamber, is difficult to form the convection current in this clearance, thereby is favorable to the inner bag to keep warm.
