In order to achieve the above object, the utility model provides a following technical scheme:
the refrigerator inner door seal comprises a sealed cabin and a main air bag in sealing connection, wherein the main air bag is semicircular, a fan-shaped inner air bag is arranged inside the main air bag, the inner air bag comprises a straight line part and an arc part which are connected, the contact surface of the main air bag and a box liner is arc-shaped, sealing small fins are arranged on the inner side outer cavity wall, cover lining sealing fins are arranged at the connection position of the sealed cabin and the main air bag, and a right angle is formed between the cover lining sealing fins and the bottom of the main air bag.
Furthermore, the angle between the linear part of the fan-shaped inner air bag and the bottom of the air bag is 110-160 degrees.
Furthermore, the bottom cavity wall of the contact surface close to the main airbag is provided with reinforcing ribs with two symmetrical sides.
The utility model has the advantages as follows:
1. the straight line part of the fan-shaped inner air bag plays a supporting role, and the air bag is prevented from being deformed too much when the door body is closed. When the refrigerator door is opened, the arc part of the refrigerator door is restored to the original shape quickly, the buffer effect is achieved in the opening and closing process of the door body, and the elasticity of the inner door seal is increased.
2. The right-angle design is adopted between the cover liner sealing fin and the bottom of the main air bag, so that the cover liner sealing fin can well cover the mounting notch between the inner door seal and the refrigerator door body, the cold air is effectively prevented from leaking from the mounting gap of the door seal, and the sealing performance is improved.
3. The utility model provides an interior door seals elasticity good, and the outward appearance is succinct pleasing to the eye easily processing, and the leakproofness is good, and the double door that adopts this kind of interior door to seal seals the refrigerator and seals more showing.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application.
The first embodiment is as follows:
a refrigerator inner door seal comprises a sealed cabin 1 and a main air bag 5 which is connected in a sealing mode, wherein the main air bag 5 is semicircular, a fan-shaped inner air bag 2 is arranged inside the main air bag 5, and the inner air bag 2 comprises a straight line portion and an arc portion which are connected. When the door body is closed, the main air bag 5 is pressed, and the straight line part of the inner air bag 2 plays a supporting role, so that the main air bag 5 is prevented from being deformed too much. When the refrigerator door is opened, the arc part and the contact surface 6 of the inner air bag 2 are quickly restored to the original shape, and the buffer function is realized in the opening and closing process of the door body. Preferably, the angle between the linear part of the fan-shaped inner air bag 2 and the bottom of the main air bag 5 is 110-160 degrees, namely the angle between the linear part on the left side of the inner air bag 2 and the bottom of the main air bag 5 is 110-160 degrees, the linear parts on the two sides of the inner air bag 2 are symmetrically arranged, the inner air bag 2 provides supporting force when the door seal is extruded, cold leakage caused by overlarge deformation of the main air bag 5 is prevented, and when the extrusion force of the door seal disappears, counterforce is provided, so that the door seal is quickly restored to the original shape, and the deformation resilience of the door seal is improved. Meanwhile, the lower part of the inner air bag 2 shares a connecting rib with the sealed cabin 1, and the inner air bag 2 is not directly connected with other parts of the main air bag 5, so that the main air bag 5 cannot be damaged due to the traction of the inner air bag 2. The contact surface 6 of the main airbag 5 and the box liner is arc-shaped, when the door body is closed, the arc-shaped contact surface 6 is attached to the door liner, the contact area of the door seal and the door liner is increased, and the sealing performance is enhanced. Preferably, the contact surface 6 is provided with reinforcing ribs 3 with two symmetrical sides on the bottom cavity wall close to the main airbag 5, the joints of the reinforcing ribs 3 and the linear part and the arc part of the inner airbag 2 are positioned at the same height, so that the strength of the inner door seal can be increased, and the contact surface 6 is prevented from being broken after long-time use to influence the sealing property.
