Detailed Description

The utility model is further illustrated with reference to the following figures and examples.

As shown in fig. 1 and 2, a sealing structure for an electric oven comprises a box body 1, a heating cavity 2 for placing a heated object is formed in the box body 1, an opening 3 communicated with the heating cavity 2 is formed in the top of the box body 1, a supplement part 4 is detachably installed at the opening 3, and a sealing ring 5 is arranged between the supplement part 4 and the opening 3; the top of the sealing ring 5 is provided with a sealing part A which is abutted against the bottom end face of the vacancy filling piece 4, and the inward surface of the sealing ring 5 extends to form an elastic sealing lip B which is abutted against the side end face of the vacancy filling piece 4.

When the benefit of the different functions lacks piece 4 and use on opening the mouth, the seal structure of this structure realizes airtight processing to heating chamber 2, prevents that the heat in the heating chamber 2 from leaking through the gap of mending between lacking piece 4 and opening 3, reduces the heating efficiency of electric oven to the heat that prevents to leak causes the user to be difficult to be close to and mends lacking the piece and cook.

As shown in fig. 2 to 5, the supplement unit 4 includes a lid 41 and/or a cooking vessel 42, and the lid 41 and the cooking vessel 42 are alternatively placed at the opening 3.

The cooking vessel 42 includes a frying pan and a pan body.

When the supplement piece 4 only has the box cover 41, the functions realized by the box cover 41 mainly comprise shielding the open opening 3 and sealing the heating cavity, and the box cover 41 can be detached for complete cleaning after use;

when the vacancy supplementing piece 4 comprises the box cover 41 and the frying pan 42, the box cover 41 can be replaced by the frying pan besides the functions, the heating pipe 9 in the heating cavity heats the bottom of the frying pan, so that a user can realize the functions of decocting and the like on the frying pan and can roast other foods in the heating cavity while realizing the decocting function;

or the frying and baking tray is placed in the heating cavity for bearing food, and the cover 41 covers and seals the open port, so that the gap filling piece 4 is multifunctional.

The case lid 41 is placed at the opening 3, the edge bottom surface of the case lid 41 is pressed against the sealing portion a, the cooking utensil 42 extends to form a flanging 421, when the cooking utensil 42 is placed at the opening 3, the bottom surface of the flanging 421 is pressed against the sealing portion a, and the elastic sealing lip B is pressed against the outer side wall of the cooking utensil 42 in a sealing manner.

The sealing portion a is the tip end face 51 of the sealing ring 5 (visible in fig. 3/5/7), or alternatively an annular sealing projection 52 extends on the tip end face.

The elastic sealing lip B is one or more flat rings 53 obliquely arranged on the inward surface of the sealing ring 5 (visible in figure 3/5), or is the inner part of the sealing ring 5, and the inward surface 501 of the sealing ring 5 is matched with the shape of the outer side wall of the cooking vessel 42 (shown in figures 6 and 7); the elastic sealing lip B can be attached to the outer side wall of the cooking vessel 42 to realize sealing and prevent heat from leaking from the gap during heating.

The opening 3 is extended with a level difference bearing surface 301 which is annularly arranged, the sealing ring 5 is fixedly arranged on the level difference bearing surface 301, the gap supplementing piece 4 of the structure does not occupy the space of the electric oven, the whole structure of the electric oven is kept regular, and the level difference bearing surface 301 can position and fix the gap supplementing piece 4 and limit the gap supplementing piece to slide towards the horizontal direction.
