As shown in fig. 1 to 7, the air deflector 50 of the embodiment of the present invention is rotatably installed at the air outlet 12 of the indoor unit of the wall-mounted air conditioner for guiding the air outlet direction of the air outlet 12. The outlet 12 of the wall-mounted air conditioning indoor unit is generally elongated with its longitudinal direction extending in the horizontal transverse direction X, so that the air deflector 50 may be elongated with its longitudinal direction parallel to the longitudinal direction X of the outlet 12, and the axis X of rotation of the air deflector 50 is parallel to the longitudinal direction X.

As shown in fig. 2-7, the air deflection panel 50 of embodiments of the present invention may generally include an outer panel body 51, an inner panel body 52, and at least one mounting arm 55. The inner panel 52 and the outer panel 51 are positioned so that the side facing each other is the inner side and the side facing the outside is the outer side. When the air guide plate 50 is in a state of closing the outlet 12, the outer side of the outer plate 51 faces the outside of the casing 10, and the outer side of the inner plate 52 faces the inside of the casing 10.

The inner panel 52 covers the inner side of the outer panel 51 with a gap from the outer panel 51. The inner side surface of the inner plate 52 has mounting bosses 524. The mounting boss 524 is elongated to extend in the longitudinal direction (X direction) of the inner plate 52, and at least one positioning hole 5201 penetrating the inner plate 52 is formed in the mounting boss 524. The number of positioning holes 5201 is the same as the number of mounting arms 55. The installation bosses 524 are provided to reinforce the structure of the inner plate body 52.

The other end of the mounting arm 55 is rotatably connected to the casing 10 of the wall-mounted air conditioning indoor unit to rotatably connect the air guide plate 50.

In the embodiment of the present invention, the inner plate 52 and the outer plate 51 form a double-layer structure, and a gap is formed between the two layers of plates, so that the air guiding plate 50 forms a hollow structure, which makes the structural strength larger and the deformation resistance stronger. The hollow structure between the inner plate 52 and the outer plate 51 also reduces the risk of condensation on the leeward side of the air deflector 50 in the cooling mode. In addition, the mounting arm 55 is directly clamped to the inner plate 52, so that the inner plate 52 is designed to be a basic component with the highest strength, the outer plate 51 and the mounting arm 55 are both mounted on the inner plate 52, and the whole structure of the air deflector 50 is more stable. In addition, the positioning and clamping of the mounting arm 55 are simultaneously realized by the positioning block 555, and the design is very ingenious.

Specifically, the outer plate body 51 may be made of PC + ABS material, and the inner plate body 52 may be made of PC + GF material. The plastic part manufactured by the extrusion process has small difference of heat conduction coefficients, and compared with the injection molding process, the internal stress is reduced, the deformation of the air deflector 50 is improved, and the disassembly and assembly structure is simpler. The present embodiment designs the mounting arm 55 as a separate component from the inner plate 52 and the outer plate 51, which facilitates the manufacture of the inner plate 52 and the outer plate 51 through a die extrusion process.

In some embodiments, the inner plate 52 may further have two insertion holes 5202 extending therethrough, which are respectively located on two sides of the positioning hole 5201. The end of mounting arm 55 also has two clip portions 551 which are located on either side of locating block 555 and spaced from locating block 555. The two plate portions 551 are inserted into the two insertion holes 5202, respectively, so as to be clamped on both sides of the mounting boss 524 in the width direction, respectively, to make the position of the mounting arm 55 more stable, referring to fig. 4, 5, and 7.
