Embodiment 1

[0039] like Figure 1 ~ Figure 4 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; the sealing portion 22 has a V-shaped structure, and one end of its opening is connected to the The installation part 21 is integrally connected; when the cover assembly 1 is fastened on the cooking vessel 3, the bent end of the sealing part 22 abuts against the open edge 31 of the cooking vessel 3; The opening of the sealing portion 22 of the V-shaped structure faces the outside of the sealing ring 2 . The setting of the V-shaped structure can reduce the extrusion deformation stress of the sealing part of the sealing ring when the cover plate assembly is fastened to the cooking vessel, that is, the sealing ring is easy to deform and the sealing effect ...

Embodiment 2

[0053] This embodiment provides a cover assembly 1, such as figure 1 and figure 2 As 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. The cover plate assembly of this embodiment is provided with a V-shaped sealing ring, so that when it is fastened to the cooking vesse...

Embodiment 3

[0055] 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. The upper cover assembly of this embodiment is provided with a V-shaped sealing ring, so that when it is fastened to the cooking vessel, the extrusion deformation stress of the sealing part of the sealing ring is reduced, that is, the sealing ring is easy to deform, and the sealing effect is better; V The opening of the sealing part of the type structure faces the outside of the sealing ring, making it easier for the sealing part to return to its original shape when it is not 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; the sealing part is of a V-shapedstructure, and the end with the opening is integrally connected with the installation part; when the cover plate component is buckled on a cooking ware, the bent end of the sealing part abuts againstthe edge of an opening of the cooing ware; the opening of the sealing part of the V-shaped structure faces the outer side of the seal ring. Accordingly, by arranging the sealing part to be of the V-shaped structure, when the cover plate component is buckled on the cooking ware, extrusion deformation stress of the sealing part of the seal ring is lowered, that is to say, the seal ring is likely todeform, and the sealing effect is better; the opening of the sealing part of the V-shaped structure faces the outer side of the seal ring, and the sealing part is more likely to recover when the sealing part is not 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...
