That is, the sealing strip 822 and the sealing rib 21 are cooperatively filled in the gap at the matching position of the upper door body 101 and the lower door body 102, so that the sealing performance of the door body 100 is improved, and unnecessary waste is avoided.

The sealing rib 21 is arranged on the side frame 2 of the lower door body 102 close to the upper door body 101, and under the opening state, the lower end of the sealing strip 822 is lapped on the upper surface of the side frame 2, the lower end of the sealing strip 822 extends to the side frame 2 of the lower door body 102, namely, the double sealing effect is achieved between the upper door body 101 and the lower door body 102, and the sealing effect between the upper door body 101 and the lower door body 102 is improved.

In the present embodiment, the door panel 10 and the side frame 2 are both curved, and the side frame is easily deformed, so the sealing rib 21 can also improve the structural strength of the side frame 2, and preferably, the width and height dimensions of the sealing rib 21 are both 1.0 mm-2.0 mm.

Further, as shown in fig. 13, the door body 100 includes a first sealing structure 82 disposed on the upper door body side frame 2, the first sealing structure 82 includes a clamping member 831 fixed to the side frame 2, and a pair of sealing strips 822 are connected to a lower portion of the clamping member 821 at intervals. In this embodiment, the clamping member 821 is used for connecting the side frame 2, is made of a PVC material with a high hardness, and is conveniently fixedly connected with the clamping hook portion 25 of the side frame, the sealing strip is made of a PVC material with a soft material, and in the process of being matched with the side frame 2, the sealing strip 822 deforms, so that the sealing strip is favorably filled between the upper door body 101 and the lower door body 102.

Further, joint piece 821 has the ascending joint chamber of opening, the joint intracavity is equipped with pothook groove 8221, the mutual joint cooperation of pothook piece 25 and pothook groove 9211 of side frame 2 makes things convenient for the installation and the dismantlement of sealing strip 822.

The door body further comprises a second sealing structure 83 arranged on one side, far away from the door panel, of the side frame 2, the second sealing structure 83 is arranged on the side frame 2, far away from the door panel 10, of the upper door body 101 and the lower door body 102, the second sealing structure 83 comprises a clamping piece 821 used for being fixed with the side frame 2 and a sealing piece 831 connected to the side portion of the clamping piece 821 and extending downwards, and in the opening state, the sealing piece 831 is filled between the side frame 2 and the cabinet opening 201. In this embodiment, the structure of the clip 83 is the same as that of the clip 821 of the first sealing structure 82, the clip 821 is used for being matched and fixed with the side frame 2, and the sealing member 831 is located at the side of the clip 821. Similarly, the sealing element 831 is made of a PVC material made of a softer material, and in the process of matching with the side frame 2, the sealing element is easy to deform, so that the sealing element is favorably filled between the upper door body 101 or the lower door body 102 and the cabinet opening 201, and the sealing performance is improved.

Further, as shown in fig. 14, the second sealing structure 83 further includes a connecting member connecting the clip member 821 and the sealing member 831, and an avoiding groove 833 is formed between the clip member 821, the connecting member 832 and the sealing member 831. The design of dodging groove 833 provides for the deformation of sealing member 831 and lets the space, and sealing member 831 produces deformation along with last door body 101 and lower door body 102 relative slip, promotes sealing performance, moreover, sealing member 831 can not influence joint 821 with the fixed coordination of side frame 2 when producing deformation.

To sum up, the utility model discloses a door body 100 has increased the firm degree of frame through the grafting cooperation between horizontal frame 1 and the side frame 2 and the setting of apron 4, simultaneously, apron 4 covers in the butt joint department with horizontal frame 1 and side frame 2, can eliminate the exposed problem that easy deposition appears in the outside of butt joint department, still increases the pleasing to the eye degree of outward appearance of a body 100, and then promotes customer's use and experiences.
