[0024] The pipe connection structure in the present invention includes a first ventilation pipe 30, a second ventilation pipe 40 and an air conditioning pipe 50. The first ventilation pipe 30 is inserted into the first penetration hole 21 of the wall 20. The second ventilation pipe 40 and the air conditioning pipe 50 are arranged in parallel to be inserted into the second penetration hole 22 of the wall 20. The air conditioner is ventilated with the outside through the first ventilation pipe 30 and the second ventilation pipe 40, and the refrigerant is communicated with the air conditioner outdoor unit through the air conditioning pipe 50, so that the normal operation of the air conditioner can be achieved. In addition, by making the first ventilation pipe 30 inserted into the first penetration hole 21 alone, and the second ventilation pipe 40 and the air conditioning pipe 50 inserted into the second penetration hole 22 in parallel, the installation of the pipe connection structure and the connection between the air conditioner indoor unit and the outside can be achieved more conveniently, thereby solving the problem of the complicated outdoor pipe connection installation method of the air conditioner in the prior art.

[0025] In this embodiment, if Figure 1 As shown, the pipe connection structure further includes: a drain pipe 60, which is used to connect to the water receiving pan of the air conditioner indoor unit 10. The drain pipe 60 is arranged in parallel with the second ventilation pipe 40 and the air conditioning pipe 50, so as to be jointly penetrated in the second penetration hole 22. By arranging the drain pipe 60 and connecting the drain pipe 60 to the water receiving pan of the air conditioner indoor unit 10, drainage of the water receiving pan can be achieved more conveniently.

[0026] In this embodiment, if Figure 1 As shown, the pipe connection structure further includes: an indoor-outdoor unit connection line 70, which is used to connect the air conditioner indoor unit 10 and the air conditioner outdoor unit to supply power to the air conditioner outdoor unit; the indoor-outdoor unit connection line 70 is arranged in parallel with the second ventilation pipe 40, the air conditioner pipe 50 and the drainage pipe 60 to be jointly penetrated in the second penetration hole 22.

[0028] In order to realize the refrigerant transmission between the air-conditioning indoor unit 10 and the air-conditioning outdoor unit, the air-conditioning pipe 50 includes a refrigerant inlet pipe and a refrigerant outlet pipe, and the refrigerant inlet pipe and the refrigerant outlet pipe are both connected between the air-conditioning indoor unit 10 and the air-conditioning outdoor unit, so that the air-conditioning indoor unit 10 and the air-conditioning outdoor unit can circulate the refrigerant through the refrigerant inlet pipe and the refrigerant outlet pipe.

[0029] Specifically, the air conditioner indoor unit 10 includes a fresh air device 11, a first ventilation duct 30 is used to connect to the fresh air inlet of the fresh air device 11 to provide fresh air to the fresh air device 11, and a second ventilation duct 40 is used to connect to the exhaust outlet of the fresh air device 11 so that the fresh air device 11 can exhaust air through the second ventilation duct 40.

[0030] Since the ventilation volume required by the first ventilation duct 30 for supplying fresh air to the fresh air device 11 is large and the diameter of the first ventilation duct 30 is large, the first ventilation duct 30 is separately inserted into the first insertion hole 21 of the wall 20. The second ventilation duct 40 is used for exhausting air from the fresh air device 11 and has a small exhaust volume and the diameter of the second ventilation duct 40 is small, so the second ventilation duct 40 and other connecting pipes or connecting lines of the air conditioner indoor unit 10 are inserted into the second insertion hole 22 together.

[0031] like Figure 1 As shown, the fresh air device 11 includes an indoor wind box 111, and the fresh air inlet and exhaust outlet are both arranged on the indoor wind box 111. The first ventilation duct 30 is connected to the indoor wind box 111 through the fresh air indoor joint 31, and the second ventilation duct 40 is connected to the indoor wind box 111 through the exhaust air indoor joint 41.

[0032] To prevent rainwater and other debris from entering the air conditioner indoor unit, Figure 1 As shown, the pipe structure further includes: a rain cover assembly 80 , and the first ventilation pipe 30 and the second ventilation pipe 40 are both connected to the rain cover assembly 80 to communicate with the outside through the rain cover assembly 80 .

[0034] In addition, the connecting pipe structure also includes a signal line and / or a temperature sensing line for connecting the air conditioner indoor unit and the air conditioner outdoor unit. The signal line and / or the temperature sensing line are arranged in parallel with the second ventilation pipe 40 so as to be passed through the second penetration hole 22 together with the second ventilation pipe 40.

[0035] The present invention further provides an air conditioner, comprising an air conditioner outdoor unit, an air conditioner indoor unit and a connecting pipe structure, wherein the connecting pipe structure is the connecting pipe structure mentioned above.

[0036] The present invention solves the problem of a large number of holes for the exhaust duct of the fresh air machine and the fresh air duct, and the inconvenience of the duct connection by designing a solution in which the exhaust duct of the full-heat fresh air air conditioner passes through a wall hole together with the air conditioning duct, drainage pipe, internal and external unit connection wires, and communication wires (signal wires and temperature sensing wires), and the fresh air duct passes through another wall hole alone. At this time, the two through holes (the first through hole and the second through hole) are arranged on the wall 20 with the same diameter.

[0037] The present invention designs an integrated and convenient pipe installation method for the exhaust duct and air conditioning pipe of a full-heat fresh air air conditioner. The indoor end of the exhaust duct is connected to the exhaust side air outlet of the fresh air machine wind box (indoor pipe), and the outdoor end is connected to the dirty air side air outlet of the rain cover assembly to form an exhaust passage. The indoor end of the fresh air duct is connected to the air outlet on the fresh air side of the fresh air machine wind box (indoor pipe), and the outdoor section is connected to the fresh air side air outlet of the rain cover assembly to form a fresh air passage.

[0038] The air conditioning pipes include the refrigerant inlet pipe and refrigerant outlet pipe of the evaporator, which are connected to the outdoor unit. The drainage pipe is connected to the insulation drainage pipe of the indoor water tray and passes through the wall hole to the outside.

[0039] After-sales installation method of the pipe structure:

[0040] The fresh air duct (first ventilation duct 30) is fixed to the fresh air side air outlet of the indoor air box of the fresh air device through the fresh air indoor joint, passes through the through hole on the rear cover 12 of the air inlet component, and passes through the wall hole (first penetration hole 21). The after-sales installation personnel cut off the excess length of the fresh air duct according to the required length and connect it to the fresh air outdoor joint (first outdoor joint 32).

[0041] The exhaust duct is fixed to the dirty air side air outlet of the indoor air box of the fresh air device through the indoor exhaust joint. The exhaust duct is wrapped together with the air conditioning pipe, drain pipe, and indoor and outdoor unit connecting lines, and passes through another wall hole (the second penetration hole 22) to the outdoors. The exhaust duct is cut according to the required length and connected to the outdoor exhaust joint (the second outdoor joint 42). The fresh air duct that has been assembled with the fresh air outdoor joint and the exhaust duct with the exhaust outdoor joint are assembled on the rain cover assembly 80 and then fixed on the wall.

[0042] The air conditioning pipes and the connecting wires of the indoor and outdoor units are bundled together and assembled to the outdoor unit. The drainage pipe is installed in a place where drainage can be carried out according to the situation.

[0043] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0044] The pipe connection structure in the present invention includes a first ventilation pipe 30, a second ventilation pipe 40 and an air conditioning pipe 50. The first ventilation pipe 30 is inserted into the first penetration hole 21 of the wall 20. The second ventilation pipe 40 and the air conditioning pipe 50 are arranged in parallel to be inserted into the second penetration hole 22 of the wall 20. The air conditioner is ventilated with the outside through the first ventilation pipe 30 and the second ventilation pipe 40, and the refrigerant is communicated with the air conditioner outdoor unit through the air conditioning pipe 50, so that the normal operation of the air conditioner can be achieved. In addition, by making the first ventilation pipe 30 inserted into the first penetration hole 21 alone, and the second ventilation pipe 40 and the air conditioning pipe 50 inserted into the second penetration hole 22 in parallel, the installation of the pipe connection structure and the connection between the air conditioner indoor unit and the outside can be achieved more conveniently, thereby solving the problem of the complicated outdoor pipe connection installation method of the air conditioner in the prior art.
