Embodiment 1

[0053] Such as Figure 1 to Figure 9 As shown, the sealing ring on a cover plate assembly of this embodiment includes an integrally connected installation part 21 and a sealing part 22. On one side of the assembly 1 , the sealing portion 22 extends from one side of the cover assembly 1 in a direction away from the cover assembly 1 ; when the cover assembly 1 is fastened on the cooking vessel 3 , the sealing part 22 abuts on the open edge 31 of the cooking vessel 3 and the side surface of the sealing part 22 outside the cooking vessel 3 is provided with an elastic structure for reducing the compression deformation stress of the sealing part 22; By arranging the elastic structure, the stress of extrusion deformation of the sealing ring is reduced, so that the sealing ring can easily return to its original shape after being squeezed.

[0054] The installation part 21 of the present embodiment can adopt the connection ring of the continuous ring structure, also can be the discont...

Embodiment 2

[0073] A cover assembly such as figure 1As shown, the cover plate assembly 1 includes a cover plate body 12, a ring-shaped pressure plate 11 and a sealing ring 2 as described in Embodiment 1, and the pressure plate 11 is crimped on the peripheral edge of the cover plate body 12 And an annular gap 13 is formed between the cover plate body 12, the mounting part 21 is sealed and crimped in the annular gap 13 and is located on the inner ring side of the pressure plate 11, and the longitudinal section is "Γ" shaped The mounting part 21 is crimped in the annular gap 13, so that the clamping between the mounting part 21 and the pressure plate 11 is firmer; the sealing part 22 extends from the annular gap 13 in a direction away from the cover plate assembly 1 and the annular The gap 13 is sealed and covered. In the cover plate assembly of this embodiment, an elastic structure is provided on the outside of the joint between the sealing ring and the open edge of the cooking vessel, whi...

Embodiment 3

[0075] This embodiment provides an upper cover assembly, including a cover body and the cover assembly 1 as described in Embodiment 2, and the other side of the cover assembly 1 is connected to the cover body. In the upper cover assembly of this embodiment, an elastic structure is provided on the outside of the joint between the sealing ring and the open edge of the cooking vessel, which reduces the stress of extrusion deformation of the sealing ring, and makes the sealing ring easy to return to its original shape after being squeezed.

Abstract

The invention relates to a seal ring on a cover plate component, the cover plate component, an upper cover component and an electric appliance. The seal ring comprises an installation part and a sealing part which are integrally connected, the longitudinal cross-section of the installation part is shaped like an upside-down L, the installation part is installed on one side face of the cover platecomponent in a sealed mode, and the sealing part extends out of one side face of the cover plate component in the direction deviating from the cover plate component; when the cover plate component isbuckled on a cooking ware, the sealing part abuts against the edge of an opening of the cooing ware, and an elastic structure used for lowering the extrusion deformation stress of the sealing part isarranged on the side face, located outside the cooking ware, of the sealing part. Accordingly, the sealing part is arranged to be of a V-shaped structure, stiffener is arranged on the inner side of the bending part of the V-shaped structure, the elastic structure is arranged on the stiffener, the rigidity of the seal ring is enhanced, the extrusion deformation stress of the seal ring is lowered, and the seal ring is likely to recover after being extruded.

Description

technical field [0001] The invention relates to the technical field of small household appliances, in particular to a sealing ring on a cover assembly, a cover assembly, an upper cover assembly and an electrical appliance. Background technique [0002] In the current electric pressure cooker, electric rice cooker and other products, due to the structural design of the sealing ring, the condensed water generated during the cooking process or the condensation process is easy to condense in the sealing ring, and the condensed water slips on the rice cooker shell after the user opens the cover. In the hood, it will affect the experience effect of customers, and more seriously, it will cause complaints from users due to problems caused by water. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sealing ring on the cover plate assembly, a cover plate assembly, an upper cover assembly and an electrical appliance for the...
