[0035] In the present invention, at least one sealing ridge 4 distributed along the length direction of the sealing surface 3 is provided on the sealing surface 3 where the door body 2 contacts the door frame body 1. Since the sealing ridge 4 is raised from the sealing surface 3, when the door body 2 is closed, there is a line contact between the sealing ridge 4 and the door frame body 1. Compared with the traditional surface contact, the sealing ridge 4 makes the actual contact area more concentrated and effective, so that the pressure distribution on the sealing surface 3 is more uniform. The sealing ridge 4 bears most of the pressure, which increases the local pressure of the door frame body 1, thereby greatly enhancing the sealing effect of the sealing surface 3.

[0036] Specifically, combined Figures 3-5 As shown, two sealing ridges 4 distributed along the length direction of the sealing surface 3 are symmetrically provided on the sealing surface 3 where the door body 2 contacts the door frame body 1 , and a sealing area 5 is formed between the two sealing ridges 4 and the sealing surface 3 .

[0037] Two sealing ridges 4 are symmetrically provided on the sealing surface 3 to form a double seal, which can make the pressure distribution on the sealing surface 3 more uniform. The sealing ridges 4 can provide additional pressing force to ensure the sealing performance of the sealing area 5.

[0038] Preferably, combined Figures 3-5 As shown, a sealing rubber cotton 6 is bonded to the sealing surface 3.

[0039] The sealing rubber cotton 6 bonded to the sealing surface 3 can adapt to the sealing surface 3 and the sealing ridge 4 to further enhance the sealing performance of the sealing surface 3.

[0040] Specifically, combined Figure 5 As shown, the sealing ridge 4 is integrally arranged with the sealing surface 3 .

[0044] The door body 2 is combined by the profile frame 8, the inner panel 9 and the outer panel 10, and has stable structure and good sealing performance. The combination mode is simple and easy to maintain. The polyurethane foaming plate 11 between the inner panel 9 and the outer panel 10 has low thermal conductivity and excellent heat insulation performance, which can prevent the loss of cold and heat energy and improve the efficiency of the air conditioning unit, thereby reducing energy consumption and operating cost.

[0045] The profile frame 8 made of PVC material is relatively light in weight while ensuring the structural strength, and the cooperation between the profile frame 8 made of PVC material and the inner panel 9 and the outer panel 10 is relatively close, which can improve the sealing performance of the door body 2.
