Therefore, two seals can be formed between the back air duct cover plate 124 and the inner container of the freezing chamber 1, the sealing reliability is better, and the disassembly and the assembly are more convenient.
Because the width of the top-mounted duct cover 117 is larger and the width of the back duct cover 124 is generally smaller, in order to make the transition from the connection with the top-mounted duct cover 117 more natural and to accommodate other components, referring to fig. 2 and 12, in some embodiments, the width of the upper portion of the back duct cover 124 is larger than the width of the lower portion, and because the width of the back duct outlet 122 is generally smaller than the distance between the two sealing plates 127, a passage may be formed between the two sealing plates 127, in order to provide a guide for cool air and thus shorten the path, the two sealing plates 127 may extend toward the upper region of the back duct cover 124, forming an extension 128, and in order to allow the entire back duct 123 to be uniformly ventilated, the top surface of the extension 128 is lower than the top surface of the back duct cover 124 in the vertical direction.
Referring to fig. 2, 15 and 16, in some embodiments, in order to prevent the back duct cover plate 124 from being deformed, the back duct cover plate 124 includes an upper cover plate 1241 and a lower cover plate 1242, and the upper cover plate 1241 and the lower cover plate 1242 are clamped by a third sealing clamping structure for easy assembly and disassembly. In other embodiments, the back duct cover plate 124 is a unitary piece. In other embodiments, the back duct cover plate 124 includes an upper cover plate 1241 and a lower cover plate 1242, and the upper cover plate 1241 and the lower cover plate 1242 are connected by bolts and sealed by a sealing member, so that the connection is more reliable.
When the embodiment is adopted in which the back air duct cover plate 124 includes an upper cover plate 1241 and a lower cover plate 1242, and the upper cover plate 1241 and the lower cover plate 1242 are clamped by a third sealing and clamping structure, in some embodiments, the third sealing and clamping structure includes a first sealing section 1243 and a second sealing section (not shown), wherein the first sealing section 1243 is disposed at a lower portion of the upper cover plate 1241, a third clamping groove 1244 is disposed on the first sealing section 1243, the second sealing section is disposed at an upper portion of the lower cover plate 1242, and a third clamping claw 1245 matched with the third clamping groove 1244 is disposed on the second sealing section; after the upper cover plate 1241 and the lower cover plate 1242 are fastened, the third clamping jaw 1245 is clamped in the third clamping groove 1244, and the first sealing section 1243 and the second sealing section are overlapped and pressed and sealed. Therefore, the disassembly and assembly are more convenient.
Referring to fig. 5 and 6, in some embodiments, a water collection sump (not shown) is also disposed within overhead air duct assembly 11, and is connected to evaporator 13, and overhead air duct cover 117 is provided with a drain 1176 for draining accumulated water from the water collection sump. In some embodiments, overhead duct cover 117 provides drain 1176 with a thickness that is less on one side than on the other side. Specifically, when the water outlet 1176 is disposed at the rear right side of the top-mounted air duct cover 117, the thickness of the rear portion of the top-mounted air duct cover 117 is smaller than that of the front portion, and the thickness of the right side is smaller than that of the left side, so that the accumulated water in the water collecting tank can more smoothly enter the water discharging pipe through the water outlet 1176.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
