Fig. 1 is a schematic view of an overall structure of a refrigerator according to an embodiment of the present utility model. Fig. 2 is a schematic structural view of a door seal according to an embodiment of the present utility model. FIG. 3 is an enlarged cross-sectional view of one of the door seals according to one embodiment of the present utility model. In one embodiment, as shown in fig. 1, 2 and 3, the refrigerator 1 has a door body 10 and a case 11, a door seal 2 is mounted on the door body 10 of the refrigerator 1, the door seal 2 has an air bag portion 20, and the air bag portion 20 has two side walls 21 extending from the door body 10 of the refrigerator 1 toward the case 11 of the refrigerator 1, both of the side walls 21 being inclined toward the outside of the refrigerator 1, so that the door seal 2 is inclined toward the outside of the refrigerator 1 as a whole. Thereby make impurity such as water stain, oil stain, dust be difficult for piling up on the surface of door strip of paper used for sealing 2, and then reduced the erosion of impurity such as water stain, oil stain, dust to door strip of paper used for sealing 2 to the life of door strip of paper used for sealing 2 has been promoted.

Specifically, as shown in fig. 1, 2 and 3, a door seal 2 is provided around the door body 10 of the refrigerator 1, the door seal 2 has an air bag portion 20, and both sides of the air bag portion 20 have side walls 21, the side walls 21 extend in a direction of the door body 10 of the refrigerator 1 toward the cabinet 11 of the refrigerator 1, and the outer surfaces of the side walls 21 are smooth and wrinkle-free, and furthermore, both the side walls 21 are inclined toward the outside of the refrigerator 1, so that the air bag portion 20 is inclined outward as a whole, and thus the door seal 2 is inclined toward the outside of the refrigerator 1 as a whole.

Here, the inclination to the outside of the refrigerator 1 described herein, in the closed state of the door 10, is the inclination from the door 10 to the cabinet 11, meaning that the sidewall 21 is inclined in the direction of the inside of the door 10 toward the peripheral edge of the door 10. That is, the door seal 2a of the upper portion of the door body 10 is inclined toward the top of the refrigerator 1, the lower door seal 2b is inclined toward the bottom of the refrigerator 1, and the door seal 2c of the left side of the door body 10 is inclined toward the left outside of the refrigerator 1, and the door seal 2d of the right side of the door body 10 is inclined toward the right outside of the refrigerator 1, so that the door seals 2 around the door body 10 are all inclined toward the respective outer directions, thereby enabling the door body 10 of the refrigerator 1 to be effectively sealed together when the door body 11 is closed.

Therefore, in the daily use process of the door body 10 of the refrigerator 1, impurities such as water stains, oil stains and dust cannot be easily attached to and accumulated on the door seal 2, so that erosion of the impurities such as the water stains, the oil stains and the dust to the door seal 2 is reduced, and the service life of the door seal 2 is prolonged.

In addition, the door seal 2 on each side around the door body 10 is inclined towards the corresponding external direction, so that the door seal 2 is more convenient in cleaning, and impurities such as water stains, oil stains and dust attached to the door seal 2 are easier to remove, thereby further prolonging the service life of the door seal 2.

In this embodiment, through setting up the door strip of paper used for sealing 2 that has gasbag portion 20, and the lateral wall 21 of the both sides of gasbag portion 20 inclines towards the outside of refrigerator 1, thereby make the door strip of sealing 2 of every side on the door body 10 all incline towards the outside that corresponds respectively, thereby make impurity such as water stain, oil stain, dust be difficult for adhering to the surface at door strip of sealing 2, in addition, because door strip of sealing 2 has gasbag portion 20 and lateral wall 21, make the surface of door strip of sealing 2 not have the fold and more smooth, thereby further make impurity such as water stain, oil stain, dust be difficult for adhering to the surface at door strip of sealing 2, thereby further promoted door strip of sealing 2's life.

Further, because the door seal 2 is integrally inclined to the outside of the refrigerator 1, the door seal 2 is more convenient when being cleaned, so that impurities such as water stains, oil stains, dust and the like are not easy to adhere to the outer surface of the door seal 2, and the service life of the door seal 2 is further prolonged.
