[0005] Compared with the prior art, the technical effects achieved by this technical solution are as follows: Compared with the prior art of directly installing the first air guide plate on the base, this technical solution utilizes the method of moving the first air guide plate outward. Specifically, by movably connecting one end of the first air guide plate to the middle frame and connecting the other end to the base through an adapter plate, the rotation axis of the first air guide plate is moved inward and outward from the air outlet, thereby increasing the air delivery range of the first air guide plate. In addition, by setting the adapter plate on one side, the installation difficulty of the first air guide plate is reduced.

[0006] In one embodiment of this utility model, the indoor unit further includes a second air guide plate, which is located at the end of the first air guide plate away from the middle frame and is rotatably connected to the first air guide plate.

[0009] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting a motor compartment at one end where the first air guide plate connects to the adapter plate, it is convenient to thread the motor wires on the base; at the same time, the setting of the wire harness structure can avoid the risk of damage caused by the motor wires moving around during the operation of the indoor unit.

[0010] In one embodiment of this utility model, the middle frame is also provided with a clearance structure that cooperates with the second air guide plate; wherein the second air guide plate rotates within the clearance structure.

[0011] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting an avoidance structure on the middle frame to cooperate with the second air guide plate, sufficient space is provided for the rotation of the second air guide plate, thereby further increasing the air guiding range of the indoor unit and improving the user experience.

[0014] In one embodiment of this utility model, the middle frame has a rim structure at both ends of its horizontal direction, and the rim structure protrudes on both sides of the middle frame.

[0015] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting up a rim structure on both sides of the middle frame, the wind is blocked in the lateral direction, thereby further improving the wind gathering and guiding effect and enhancing the user experience.

[0016] In one embodiment of this utility model, the middle frame is provided with multiple mating parts on one side corresponding to the downstream area of ​​the air outlet, and the multiple mating parts are spaced apart along the length direction of the downstream area of ​​the air outlet; the first air guide plate is provided with multiple connecting parts corresponding to the multiple mating parts, and the multiple mating parts and multiple connecting parts correspond one-to-one and are rotatably connected.

This design improves the connection stability of the first air guide plate, thereby achieving more precise air delivery angle adjustment; the design of multiple mating parts and multiple connecting parts makes the movement of the air guide plate more stable and reliable.

[0018] In one embodiment of this utility model, any mating part is provided with a shaft hole; any connecting part is provided with a rotating shaft that mates with the shaft hole.

[0020] In one embodiment of this utility model, the rotating shaft is located at the end of the connecting part away from the first air guide plate.

[0021] Compared with existing technologies, the technical effect achieved by adopting this technical solution is that by setting the rotating shaft away from the first air guide plate, the air guiding range of the first air guide plate is increased.

[0022] This utility model also provides an air conditioner, including the indoor unit of any of the above.

[0023] By adopting the technical solution of this utility model, the following technical effects can be achieved:

[0024] (1) Compared with the existing technology of directly installing the first air guide plate on the base, this technical solution uses the method of moving the first air guide plate outward.

[0039] See Figure 1 This is a structural schematic diagram of an indoor unit provided by an embodiment of the present utility model; specifically, in conjunction with... Figures 2-6 An indoor unit 100 includes: a first air guide plate 30, a middle frame 20 and a base 10 that cooperate with each other. The base 10 is provided with an upstream air outlet area 41 and the middle frame 20 is provided with a downstream air outlet area 42.

[0040] Specifically, compared to the existing technology of directly mounting the first air guide plate 30 onto the base 10, this technical solution utilizes the method of moving the first air guide plate 30 outward. Specifically, by movably connecting one end of the first air guide plate 30 to the middle frame 20 and connecting the other end to the base 10 via the adapter plate 11, the rotation shaft 331 of the first air guide plate 30 is moved inward or outward from the air outlet, thereby increasing the air delivery range of the first air guide plate 30. In addition, by setting the adapter plate 11 on one side, the installation difficulty of the first air guide plate 30 is reduced.

[0041] Specifically, the first mounting hole 22 of the first air guide plate 30 is moved from the original upstream air outlet area 41 to the downstream air outlet area 42. Correspondingly, the rotation axis of the first air guide plate 30 is also moved outward, ensuring that the air delivery range of the first air guide plate 30 is increased compared with the technical means of setting it in the upstream air outlet area 41.

[0042] In light of actual working conditions, this utility model connects one end of the first air guide plate 30 to the middle frame 20, thereby reducing the number of adapter plates 11 at one end and lowering the installation difficulty. Considering that the first air guide plate 30 needs to be driven by a motor, and the motor must be installed on the base 10, the adapter plate 11 at the end of the first air guide plate 30 connected to the motor is retained, and the first air guide plate 30 is installed to the base 10 through the adapter plate 11.

[0043] Preferably, the indoor unit 100 further includes a second air guide plate 50, which is located at the end of the first air guide plate 30 away from the middle frame 20 and is rotatably connected to the first air guide plate 30.

[0044] Specifically, by setting the second air guide plate 50 and rotating the second air guide plate 50 and the first air guide plate 30, the air guiding range of the indoor unit 100 is further increased.

[0051] Preferably, the middle frame 20 has a surrounding structure 232 at both ends of its horizontal direction, and the surrounding structure 232 protrudes on both sides of the middle frame 20.

[0052] Specifically, by setting up a rim structure 232 on both sides of the middle frame 20, the wind is blocked in the lateral direction, thereby further improving the wind gathering and guiding effect and enhancing the user experience.

[0054] Specifically, by setting multiple mating parts 21 on one side of the middle frame 20 corresponding to the downstream area 42 of the air outlet, and setting multiple connecting parts 33 on the first air guide plate 30, a multi-point rotational connection between the first air guide plate 30 and the middle frame 20 is realized. This design improves the connection stability of the first air guide plate 30, thereby achieving more precise air delivery angle adjustment.

[0055] Preferably, any mating part 21 is provided with a shaft hole 211; any connecting part 33 is provided with a rotating shaft 331 that mates with the shaft hole 211.
