[0047] Preferably, the outdoor air box 10 includes a plurality of side panels 112 , and at least two of the side panels 112 are provided with a second vent 15 .

[0048] In order to guide the liquid in the outdoor wind box 10, Figure 3 As shown, a guide protrusion 16 is provided on the bottom plate 111 of the outdoor wind box 10 . The guide protrusion 16 is located on the inner side of the bottom plate 111 and protrudes toward the middle of the accommodating cavity 11 to guide the liquid in the outdoor wind box 10 .

[0049] Preferably, the upper surface of the guide protrusion 16 is in communication with the second vent 15 , so that the liquid on the guide protrusion 16 flows out through the second vent 15 .

[0050] Specifically, Figure 3 As shown, the upper surface of the guide protrusion 16 is an arc-shaped surface.

[0051] The specific structure of the outdoor wind box 10 in this embodiment is as follows: Figures 1 to 4As shown, the outdoor wind box 10 includes a bottom plate 111, a back plate 113 and two side plates 112. The bottom plate 111 is a rectangular plate surrounded by a first side edge, a second side edge, a third side edge and a fourth side edge. The first side edge and the third side edge are arranged opposite to each other, and the second side edge is opposite to the fourth side edge. The two side plates 112 are respectively connected to the first side edge and the third side edge, and the back plate 113 is connected to the second side edge. The two side plates 112, the bottom plate 111 and the back plate 113 together form an installation opening 13 of the outdoor wind box 10.

[0052] The present invention also provides a pipe connection structure, such as Figure 5 As shown, it includes a first ventilation pipe body 31, a second ventilation pipe body 32 and an outer cover assembly 100. The first ventilation pipe body 31 and the second ventilation pipe body 32 are both connected to the outside through the outer cover assembly 100. The outer cover assembly 100 is the above-mentioned outer cover assembly.

[0053] In this embodiment, the second ventilation pipe body 32 is sleeved on the outside of the first ventilation pipe body 31; wherein the first ventilation pipe body 31 is an exhaust pipe connected to the fresh air device of the air-conditioning indoor unit, and the second ventilation pipe body 32 is a fresh air pipe connected to the fresh air device; or, the first ventilation pipe body 31 is a fresh air pipe connected to the fresh air device of the air-conditioning indoor unit, and the second ventilation pipe body 32 is an exhaust pipe connected to the fresh air device.

[0054] The present invention also provides an air conditioner indoor unit, such as Figure 7 As shown, it includes a main body 200 and a connecting pipe structure 210 connected to the main body 200, and the connecting pipe structure 210 is the connecting pipe structure mentioned above.

[0055] The invention solves the hidden dangers of mice and insects entering the room and the problems of short circuit of fresh air and exhaust air and backflow of rainwater by designing a square outer cover component.

[0056] The main improvements are: preventing mice from entering the fresh air vent channel by setting a grille structure; preventing the short circuit of fresh air and exhaust air by setting an outdoor wind box 10 and a ventilation component 20; and preventing rainwater from flowing back by setting a guide protrusion 16.

[0057] The pipe assembly (pipe structure 210) passes through the wall 300 to connect the outdoor cover assembly 100. Fresh air enters from the fresh air intake grille and vertical ribs of the square outdoor cover and enters the indoor fresh air outlet along the fresh air pipe (second ventilation pipe body 32). Dirty air is exhausted along the exhaust pipe (first ventilation pipe body 31) and discharged from the dirty air exhaust grille and vertical ribs of the exhaust box (ventilation component 20) and the fresh air box (outdoor air box 10). The cover assembly is fixed to the wall 300 by plastic expansion plugs and self-tapping screws.

[0058] like Figure 1As shown, the square outdoor cover is composed of a rainproof cover, an exhaust box, a fresh air box, a fresh air duct sealing rubber ring (a first sealing ring 40), and an exhaust duct sealing rubber ring (a second sealing ring 50).

[0059] like Figure 5 As shown, the connecting pipe assembly is composed of a thermal insulation sleeve 215, a fresh air pipe, an exhaust pipe, a support frame (support assembly 211), an indoor joint 214, a foam joint 213, and an exhaust pipe rubber ring 212.

[0060] The square outdoor cover prevents short circuit between fresh air and polluted air. Sealing principle:

[0061] 1. The dirty air in the exhaust duct is discharged from the room with a high wind speed, while the fresh air in the fresh air duct is introduced from the outside with a low wind speed. There is a pressure difference, which is easy to cause air leakage. The exhaust box is matched with the fresh air box through the positioning column. The exhaust box is placed on the left side of the fresh air box and fixed with screws. A stopper structure 24 is added to the fresh air box and the exhaust box for sealing to prevent the fresh air and dirty air from short-circuiting and leaking.

[0062] 2. The fresh air box is matched with the slot structure 61 on the rain cover through a buckle, buckled on the fresh air box, and finally fixed with screws. The stopper structure 24 of the rain cover cooperates with the fresh air box for sealing. This prevents the short circuit of the left dirty air and the fresh air inside the fresh air box.

[0063] 3. The fresh air box is connected to the fresh air duct by threads. The fresh air duct is a threaded blow-molded tube that can be bent. A sealing rubber ring (first sealing ring 40) is added between the fresh air box and the fresh air duct to prevent the fresh air from flowing with the air outside the duct. Then the exhaust box is connected to the exhaust duct by threads. An exhaust duct sealing rubber ring (second sealing ring 50) is added between the exhaust box and the exhaust duct to seal and prevent the fresh air in the fresh air duct and the polluted air in the exhaust duct from flowing due to the pressure difference, thus avoiding short circuit.

[0064] Principle of anti-insect and anti-rat:

[0065] like Figure 2 As shown, both sides of the fresh air box, the fresh air side and the exhaust side, are equipped with louver grilles and vertical ribs. The coordinated structure of the grilles and vertical ribs can effectively prevent rats and large insects from entering.

[0066] Principle of preventing rainwater backflow:

[0067] from Figure 2 It can be seen that the louver grilles are angled downward, and there should be no gap between the grilles when viewed from the side. However, when viewed from the bottom up at a certain angle, there is a gap of 5mm to 25mm. Grilles with this structure can prevent rainwater from flowing into the outdoor cover without affecting the exhaust of sewage and the introduction of fresh air.

[0068] from Figure 1It can be seen that when rainwater flows to the surface of the rain cover, it can flow down along the rain cover rainwater diversion curved surface structure, without causing rainwater accumulation and causing the hidden danger of flowing into the interior of the outdoor cover. Figure 3 It can be seen that even if there is condensation water or rainwater inside the outdoor cover, it can be discharged along the rainwater diversion arc structure of the fresh air box.

[0069] The exhaust box rotates 90 degrees downward, and the sewage air is discharged from the bottom. There is no need to worry about the problem of rainwater backflow, and fresh air is introduced on both sides.

[0070] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0071] (1) Solved the problem of insects and mice easily entering the room;

[0072] (2) Solved the problem of short circuit between fresh air and exhaust air;

[0073] (3) The problem of rainwater backflow has been solved.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
