[0036] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The present invention is further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0038] See also Figure 1-Figure 4 The present embodiment provides a folding air guide door 100, which includes a main board 110, a sub-board 120 and a sub-board driving mechanism; the sub-board 120 is rotatably connected to the main board 110, the main board 110 has an inner lining board 111 and an outer panel 112, the inner lining board 111 is connected to the indoor unit body 200, and the outer panel 112 is installed on the outer side of the inner lining board 111; the sub-board driving mechanism is installed on the inner lining board 111, the sub-board driving mechanism is connected to the internal controller of the indoor unit body 200 through a wire 130, and the sub-board driving mechanism is connected to the sub-board 120, and is used to drive the sub-board 120 to rotate relative to the main board 110.

[0039] Because the inner lining plate 111 of the main board 110 is directly connected to the indoor unit body 200, the sub-board driving mechanism is installed on the inner lining plate 111, so that the wire 130 connected between the sub-board driving mechanism and the internal controller of the indoor unit body 200 can be routed along the inner lining plate 111. On the one hand, the wiring convenience is improved and the assembly of the folding air guide door 100 is facilitated; on the other hand, the assembly error can be reduced and there is no need to reserve too long wire 130. Therefore, during the swinging process of the folding air guide plate 100, the wire 130 is not easy to loosen, which can ensure the connection reliability between the sub-board driving mechanism and the internal controller of the indoor unit body 200, and further, the internal controller can effectively control the sub-board driving mechanism, so that the sub-board driving mechanism can smoothly drive the sub-board 120 to rotate relative to the main board 110. In addition, when the air conditioner is cooling and blowing air in the summer, the cold air will flow outward along the inner lining plate 111 of the main board 110. Installing the sub-board driving mechanism on the inner lining plate 111 can improve the cooling effect of the cold air on the sub-board driving mechanism, so that the sub-board driving mechanism can accelerate heat dissipation, which is beneficial to improving the reliability of the sub-board driving mechanism.

[0040] The folding air guide door 100 provided in this embodiment further includes a mainboard driving mechanism, which is installed on the indoor unit body 200, and the mainboard driving mechanism is connected to the inner lining plate 111, so that the mainboard driving mechanism drives the mainboard 110 to rotate relative to the indoor unit body 200, and the rotation of the mainboard 110 can drive the sub-plate 120 to rotate synchronously. It should be noted that the inner lining plate 111 is directly connected to the mainboard driving module, has high structural strength and large force, and the sub-plate driving mechanism is installed on the inner lining plate 111, which does not affect the deformation of the inner lining plate 111.

[0041] Preferably, a cavity may be provided between the inner lining plate 111 of the main board 110 and the appearance plate 120 . Such a hollow design may reduce the temperature difference between the appearance plate 120 and the indoor environment, thereby alleviating the condensation problem on the surface of the appearance plate 120 .

[0042] Furthermore, the sub-panel driving mechanism can be installed in the cavity between the inner lining plate 111 and the appearance plate 112, and a wire threading hole is opened at one end of the inner lining plate 111 connected to the indoor unit body 200, so that the wire 130 connected to the sub-panel driving mechanism can pass through the wire threading hole and out of the cavity of the main board 110, and be smoothly connected to the internal controller of the indoor unit body 200. In this way, the sub-panel driving mechanism can be hidden in the cavity, and the main board 110 can serve as a protective structure for the sub-panel driving mechanism, which can not only reduce the risk of damage to the sub-panel driving mechanism, but also improve the aesthetics of the folding air guide door 100.

[0043] Preferably, the portion of the wire 130 located in the cavity of the main board 110 is attached to the inner lining plate 111, which is equivalent to allowing the wire 130 to be routed toward the threading hole along the inner wall of the inner lining plate 111 after being led out by the sub-board driving mechanism, thereby further improving the stability of the wire 130 and reducing the possibility of the wire 130 loosening.

[0044] A rotating shaft 150 may be provided on the sub-plate 120, and the rotating shaft 150 may be rotationally matched with the main plate 110, so that the main plate 110 and the sub-plate 120 may be rotationally matched through the rotating shaft 150; a motor 140 may be provided in the sub-plate driving mechanism, and the motor shaft of the motor 140 may be coaxially fixed with the rotating shaft 150, so that the motor 140 may directly drive the sub-plate 120, with more stable transmission and smaller torque, and the sub-plate driving mechanism may be miniaturized, so that the sub-plate driving mechanism may be smoothly installed in the cavity of the main plate 110. Specifically, the motor pressure cover 170 may be used to press and fix the motor 140 on the inner lining plate 111.

[0045] A lug 160 is provided on the inner lining plate 111 of the main board 110, and the lug 160 is rotatably connected to the indoor unit body 200, so that the inner lining plate 111 and the indoor unit body 200 can be rotatably connected, so that the folding air guide door 100 can swing relative to the indoor unit body 200 to open and close. In other words, the sub-board driving mechanism and the lug 160 are both provided on the inner lining plate 111 of the main board 110.

[0046] In addition, the appearance panel 112 and the inner lining panel 111 can be connected in a detachable manner, so that when the sub-panel driving mechanism installed in the cavity of the main board 110 needs to be repaired or replaced, the appearance panel 112 can be removed from the inner lining panel 111 to operate the sub-panel driving mechanism, which is very convenient.

[0047] See also Figure 1-Figure 4 This embodiment further provides a wall-mounted indoor unit, which includes an indoor unit body 200 and the above-mentioned folding air guide door 100, and the folding air guide door 100 is installed on the indoor unit body 200.

[0048] The wall-mounted indoor unit provided in this embodiment has all the advantages of the folding air guide door 100. On the one hand, it is convenient for wiring and assembly of the folding air guide door 100. On the other hand, the wire 130 is not easy to loosen, which can ensure the effective control of the sub-board drive mechanism by the internal controller. In addition, the cooling effect of the cold air on the sub-board drive mechanism is better, which can accelerate the heat dissipation of the sub-board drive mechanism.

[0049] This embodiment also provides an air conditioner, which includes an outdoor unit and the above-mentioned wall-mounted indoor unit, and the wall-mounted indoor unit is connected to the outdoor unit.

[0050] The air conditioner provided in this embodiment has all the advantages of the wall-mounted indoor unit. On the one hand, it is convenient to route the wires and to assemble the folding air guide door 100. On the other hand, the wire 130 is not easy to loosen, which can ensure the effective control of the sub-board drive mechanism by the internal controller. In addition, the cooling effect of the cold air on the sub-board drive mechanism is better, which can accelerate the heat dissipation of the sub-board drive mechanism.

[0051] In summary, the embodiments of the present invention disclose a folding air guide door, a wall-mounted indoor unit and an air conditioner, which overcome many technical defects of the conventional folding air guide door. The folding air guide door, the wall-mounted indoor unit and the air conditioner provided by the embodiments of the present invention are convenient for wiring, and the folding air guide door is easy to assemble, and the wires between the sub-plate driving mechanism and the internal controller of the indoor unit body are not easy to loosen.
