Example 2: referring to fig. 5 and 6, the reducing portion 11 is located in the middle of the liner 1, and the supporting portion 21 is located in the middle of the heat insulation cover 2, so that the reducing portion 11 can play a role in visual reminding for a user, and the user can clearly add water or other ingredients into the liner 1, so that the use experience of the user is improved.

Example 3: referring to fig. 7, the variable diameter portion 11 is located at the lower portion of the liner 1, and the supporting portion 21 is located at the lower portion of the heat insulation cover 2, so as to increase the proportion of the first cavity to the whole liner 1, thereby increasing the volume inside the liner 1, and further increasing the capacity of the liner 1 in a limited space.

Still further, in the above example 3, in order to facilitate placement of the steamer or the lipid-draining pot into the inner container 1, the steamer rib 12 is provided at the upper portion of the inner container 1 at a position close to the edge of the inner container, so that the steamer rib 12 can support the steamer or the lipid-draining pot to be placed into the inner container 1, thereby achieving the effect of facilitating placement of the steamer or the lipid-draining pot into the inner container 1, and increasing flexibility of the cooking appliance.

It should be noted that, in the above example 3, the liner is typically a bladder, and the bladder is typically manufactured by a stretching process, and when the bladder is produced, the side surface may automatically form the concave steamer rib, so that the steamer rib does not need to be separately processed, and further the production efficiency of the liner is improved.

In a preferred embodiment, referring to fig. 1 and 3, the cooking appliance further includes a lid 6 covering the opening edge of the inner container 1, and a sealing ring 61 is provided in the lid 6, so that after the lid 6 is covered on the opening edge of the inner container 1, the sealing ring 61 is in sealing contact with the opening edge of the inner container 1, so as to increase the tightness of the inner container 1.

The connection position of the sealing ring 61 and the liner 1 is not particularly limited, and in one embodiment, the sealing ring 61 is abutted against the outer wall of the liner 1 at the edge of the opening, so that the sealing ring 61 seals a gap between the pot cover 6 and the liner 1; in another embodiment, referring to fig. 1, the sealing ring 61 abuts against the inner wall of the opening edge of the liner 1, so that when the air pressure in the liner 1 is increased, the air pressure applies a force to the sealing ring 61 towards the outside, so that the sealing ring 61 abuts against the liner 1 more tightly, and the air tightness of the liner 1 is further increased.

The utility model can be realized by adopting or referring to the prior art at the places which are not described in the utility model.

In this specification, each embodiment is described in a progressive manner, and identical and similar parts of each embodiment are all referred to each other, and each embodiment mainly describes differences from other embodiments.
