the difference from the first embodiment is that the sealing part 33 is connected to the upper end of the deformation part 32 or the connection part of the deformation part 32 and the connection part 31, the sealing part 33 abuts against the inner pot 2 in the cover closing state, and the abutting part of the sealing part 33 and the inner pot 2 is provided with a concave-convex structure.
In the closed state, the sealing part 33 abuts against the opening of the inner pot 2 to form the sealed cavity 5, and the deformation part 32 is attached to the inner pot 2. The concave-convex structure can be arranged on the sealing part 33, and the concave-convex structure is attached to the inner pot 2 in a closed state. Preferably, the concavo-convex structure is provided on the lower surface of the sealing part 33.
An embodiment of the second aspect of the present invention provides a cooking appliance, including: a pot body comprising an inner pot 2; the cover body 1 is covered on the cooker body; and the seal ring 3 of any of the above embodiments, the connecting portion 31 of the seal ring 3 is connected to the lid body 1.
Embodiments of the second aspect of the present invention provide a cooking appliance, which includes the sealing ring 3 of embodiments of the first aspect, and thus has all the advantages of the sealing ring 3 of the first aspect.
The cooking appliance is an electric cooker or an electric pressure cooker.
To sum up, the embodiment of the utility model provides a sealing ring 3 increases on sealing ring 3 and shines line or dull polish, make sealing ring 3's surface have unevenness's effect, form sealed chamber 5 when closing the lid, concave-convex structure sets up the sealed department to the cavity at sealing 33, concave-convex structure's difference in height is less, close the concave-convex structure department of lid state and compress tightly, only small clearance, though there is a large amount of steam during cooking, but the small clearance does not go into, because the small clearance that concave-convex structure leads to when uncapping, including the opening power of sealing ring 3 self, be greater than sealed chamber 5's negative pressure effort more easily, thereby reach the mesh that the normal state was replied to sealing ring 3 after uncapping.
