The outdoor pipe structure includes a fresh air pipe 20 and an exhaust pipe 30. The fresh air pipe 20 is used to connect with the fresh air outlet of the fresh air device to supply fresh air into the fresh air device; the exhaust pipe 30 is used to connect with the polluted air outlet of the fresh air device to discharge the polluted air discharged from the fresh air device to the outside; wherein the fresh air pipe 20 and the exhaust pipe 30 are arranged at intervals, the fresh air pipe 20 is used to penetrate in the first wall hole of the wall, and the exhaust pipe 30 is used to penetrate in the second wall hole of the wall; a first protective cover 40 is provided at one end of the fresh air pipe 20 located outdoors, and a second protective cover 50 is provided at one end of the exhaust pipe 30 located outdoors, and the first protective cover 40 and the second protective cover 50 are arranged at intervals. In this way, the isolation between the fresh air and the exhaust air can be achieved to a large extent, thereby avoiding the mixing of the fresh air and the polluted air in advance, and solving the problem that the outdoor pipe structure of the air conditioner in the prior art is prone to condensation.

[0029] Preferably, the air outlet of the second protective cover 50 is arranged in a direction away from the first protective cover 40 .

[0030] In this embodiment, the outdoor pipe structure further includes: a connecting pipe, one end of which is used to connect to the indoor unit body of the air conditioner, so that the indoor unit body is connected to the outdoor unit body through the connecting pipe for refrigerant transmission; wherein the connecting pipe and the exhaust pipe 30 are arranged in parallel to be inserted into the second wall hole together. By inserting the connecting pipe and the exhaust pipe 30 together through the second wall hole, the number of holes drilled on the wall can be reduced, which facilitates the installation of the pipe of the air conditioner.

[0031] In this embodiment, the outdoor pipe structure further includes: a power line, which is used to connect the indoor unit wiring board and the outdoor unit wiring board of the air conditioner to supply power to the outdoor unit body of the air conditioner; wherein the power line and the exhaust pipe 30 are arranged in parallel to be inserted into the second wall hole together. By inserting the power line and the exhaust pipe 30 together through the second wall hole, the number of holes drilled on the wall can be reduced, which facilitates the installation of the pipe of the air conditioner.

[0032] At the same time, the outdoor pipe structure also includes: a drain pipe, which is used to connect to the water receiving pan of the indoor unit body of the air conditioner to drain the water in the water receiving pan; wherein the drain pipe and the exhaust pipe 30 are arranged in parallel to be inserted into the second wall hole together. In this way, the installation of the drain pipe can be facilitated.

[0033] In this embodiment, the first protective cover 40 includes a protective cover body, the protective cover body has an air inlet cavity, and the bottom of the air inlet cavity and both sides of the air inlet cavity are provided with air inlets connected to the air inlet cavity. By providing multiple air inlets, the air intake amount of the first protective cover 40 can be increased. Preferably, each air inlet is provided with an air inlet grille.

[0034] In order to facilitate the connection between the fresh air duct 20 and the first protective cover 40, as shown in FIG. Figure 1 As shown, a connecting pipe portion 41 is provided on the first protective cover 40 , and one end of the fresh air duct 20 located outdoors is inserted into the connecting pipe portion 41 , and a sealing ring is sandwiched between the fresh air duct 20 and the connecting pipe portion 41 .

[0035] In this embodiment, the second protective cover 50 is a tube structure, and the second protective cover 50 is sleeved on the exhaust pipe 30. The port of the tube structure away from one end of the exhaust pipe 30 is the exhaust port.

[0036] In this embodiment, the second protective cover 50 is an L-shaped tube, one tube opening of the L-shaped tube is used to connect to the exhaust port of the exhaust pipe 30, and the other tube opening of the L-shaped tube is the exhaust port.

[0037] Preferably, the exhaust port of the second protective cover 50 is arranged downward. By arranging the exhaust port of the second protective cover 50 downward, the exhausted gas in the second protective cover 50 can be prevented from flowing into the first protective cover 40 (i.e., the fresh air duct 20), thereby avoiding the premature mixing of the polluted air and the fresh air, avoiding the short circuit of the two gases, and thus avoiding condensation on the outdoor pipe structure to a large extent.

[0038] In order to prevent foreign matter from entering the second protective cover 50 , a protective net is provided at the air outlet of the second protective cover 50 .

[0040] Preferably, the fresh air duct 20 is provided with a heat-insulating layer.

[0041] In this embodiment, the fresh air duct 20 is located above the exhaust duct 30. Since the gas discharged from the exhaust duct 30 sinks, and the fresh air is more likely to be located above the dirty air, by locating the fresh air duct 20 above the exhaust duct 30, it can be ensured to a large extent that the gas sucked into the fresh air duct 20 is fresh air, thereby preventing the dirty air discharged from the exhaust duct 30 from entering the fresh air duct 20.

[0042] In addition, by setting the fresh air duct 20 above the exhaust duct 30 and the first protective cover 40 above the second protective cover 50, the fresh air duct 20 can shield the exhaust duct 30, and the first protective cover 40 can shield the second protective cover 50, and the rain-shielding function of the first protective cover 40 can be used to shield the second protective cover 50.
