By connecting the first connecting portion 38 to the connecting end plate 34 and connecting the second connecting portion 39 to the first connecting portion 38 and the driving device 40, the connecting end plate 34, the connecting member 35 and the driving device 40 can be all connected, so that the driving device 40 can drive the connecting member 35 to move, thereby causing the switch door 30 to move to open or close the air outlet 14. By making the first connecting portion 38 located in the guiding gap 24, the guiding gap 24 can limit and guide the first connecting portion 38, so that the connecting member 35 can drive the switch door 30 to move along the extending direction of the guiding gap 24.

[0066] According to some embodiments of the present invention, referring to Figure 5, the connecting member 35 is detachably connected to the driving device 40. By making the connecting member 35 detachably connected to the driving device 40, the disassembly and assembly between the connecting member 35 and the driving device 40 can be realized, facilitating the maintenance or replacement of the connecting member 35.

[0067] According to some embodiments of the present invention, referring to Figure 5 and Figure 11 , the driving device 40 includes a driving mechanism 41 and a driving plate 42. The driving mechanism 41 is connected to the driving plate 42 to drive the driving plate 42 to move in the second direction, and the connecting member 35 is connected to the driving plate 42. By connecting the driving mechanism 41 to the driving plate 42 and connecting the connecting member 35 to the driving plate 42, the driving mechanism 41 can drive the driving plate 42 to move in the second direction, and the driving plate 42 can drive the connecting member 35 so that the switch door 30 moves in the second direction to open or close the air outlet 14. By providing the driving plate 42, it is convenient to connect the connecting member 35 to the driving device 40.

[0068] According to some embodiments of the present invention, a part of the driving device 40 is opposite to the mating plate 15, and another part of the driving device 40 is opposite to the second opening area 13. Since the shielding plate 20 shields the second opening area 13, a part of the driving device 40 is opposite to the mating plate 15, and another part of the driving device 40 is opposite to the second opening area 13. Both the mating plate 15 and the shielding plate 20 can shield the driving device 40, making the driving device 40 not exposed, and the space behind the mating plate 15 and the space behind the second opening area 13 can be fully utilized. For example, by making a part of the driving device 40 opposite to the mating plate 15, the driving device 40 can make full use of the space behind the mating plate 15, increasing the space utilization rate of the housing assembly 100. Since a part of the second connecting portion 39 of the connecting member 35 is located in the second opening area 13, by making another part of the driving device 40 opposite to the second opening area 13, the driving device 40 can be closer to the connecting member 35, and the driving device 40 is easier to connect to the connecting member 35. For example, the driving device 40 includes a driving mechanism 41 and a driving plate 42, the driving plate 42 is opposite to the second opening area 13, and the driving plate 42 is connected to the connecting member 35.

[0069] According to some embodiments of the present invention, referring to Figure 2 and Figure 7 , there are two switch doors 30, and the two switch doors 30 are arranged in the second direction. The connecting ends 32 of the two switch doors 30 are both connected to the driving device 40. By setting the switch doors 30 to two, the opening and closing area sizes of the two switch doors 30 can be increased, so that the air outlet 14 can be set larger, thereby increasing the air volume. By connecting the connecting ends 32 of the two switch doors 30 to the driving device 40, the two switch doors 30 can both be driven by the driving device 40 to open or close the air outlet 14.

[0070] For example, there are two driving devices 40 arranged along the first direction. The two driving devices 40 are respectively arranged at both ends of the housing 10 along the first direction. The connecting ends 32 at one end of the two switch doors 30 along the first direction are all connected to one of the driving devices 40, and the connecting ends 32 at the other end of the two switch doors 30 along the first direction are all connected to the other driving device 40.

[0071] For example, each driving device 40 includes a driving mechanism 41 and two driving plates 42. The two driving plates 42 are respectively connected to the connecting ends 32 of the two switch doors 30. The driving mechanism 41 includes a driving motor and two gear-rack transmission mechanisms. The two gear-rack transmission mechanisms respectively correspond to the two driving plates 42. Each gear-rack transmission mechanism includes a driving gear and a transmission rack that mesh with each other. The transmission rack can extend along the second direction, and the driving rack is fixed to the corresponding driving plate 42.

[0072] The driving gear of each gear-rack transmission mechanism of each driving device 40 is drivably connected to the motor shaft of the driving motor, so as to drive the driving gear to rotate through the motor. The driving gear drives the driving rack to move along the second direction, and the driving gear-rack assembly moves, thereby driving the driving plate 42 to move along the second direction, and further enabling the connecting end 32 to move, so as to drive the switch door 30 to move along the second direction. Among them, the transmission connection mode between the two gear-rack transmission mechanisms in the driving device 40 and the motor shaft of the driving motor can be different, so that when the driving motor works, it can drive the two switch doors 30 to move in opposite directions. For example, when it is necessary to open the air outlet 14, the driving device 40 drives the two switch doors 30 to move along the second direction and away from each other; when closing the air outlet 14, the driving device 40 drives the two switch doors 30 to move along the second direction and close to each other.

The heat exchanger assembly and the fan assembly are arranged inside the housing 10.

[0074] When the air conditioner is working, the fan assembly works, driving indoor air to enter the housing 10 from the air inlet, exchanging heat with the heat exchanger assembly, and then blowing out from the air outlet 14 to the indoor, so as to adjust the indoor temperature.

[0075] Optionally, the air conditioner can be a split air conditioner. For example, the air conditioner can be a split floor-standing air conditioner. The air conditioner can include an air conditioner indoor unit and an air conditioner outdoor unit.
