Further, referring to fig. 2 to 4, fig. 2 is a schematic overall structural view of the first wind deflector of the present preferred embodiment; fig. 3 is a schematic overall structure diagram of the second wind deflector of the preferred embodiment; fig. 4 is an assembly view of the first wind deflector and the second wind deflector of the present preferred embodiment. As shown in fig. 2 to 4, the wall-mounted air conditioning indoor unit of the present invention further includes a first air deflector 13 and a second air deflector 14. Specifically, the first wind deflector 13 is a U-shaped plate structure, and of course, the specific shape of the first wind deflector 13 is not limited as long as it is entirely U-shaped, two vertical sections of the U-shaped plate structure are the connecting section 132 of the first wind deflector 13, a transverse section of the U-shaped plate structure, that is, a portion located between the two vertical sections is the wind shielding section 131 of the first wind deflector 13, and the wind shielding section 131 of the first wind deflector 13 is a non-porous plate, and the first wind deflector 13 is disposed inside the second wind deflector 14.

Based on the above structure, under the condition that the first wind deflector 13 and the second wind deflector 14 are connected in place, the two connecting sections 132 of the first wind deflector 13 and the two connecting sections 142 of the second wind deflector 14 are arranged in parallel, so that the first wind deflector 13 and the second wind deflector 14 can realize coaxial rotation.

In addition, the first wind deflector 13 and the second wind deflector 14 are connected to an end cover of the housing 11 by a rotating assembly so that the first wind deflector 13 and the second wind deflector 14 can rotate between the dust-proof position and the wind-shielding position by the rotating assembly. Specifically, the two connecting sections 132 of the first wind deflector 13 and the two connecting sections 142 of the second wind deflector 14 are connected to the left and right end covers of the housing 11 through the two rotating assemblies, so that the first wind deflector 13 and the second wind deflector 14 can rotate between the dust-proof position and the wind-shielding position through the rotating assemblies, and the rotating members are arranged to be capable of rotating the first wind deflector 13 and the second wind deflector 14 synchronously and rotating the first wind deflector 13 and the second wind deflector 14 relatively. Based on the above structure, the dustproof position is a position above the air inlet 111, and the wind blocking position is a position near the air outlet 112.

As a preferred embodiment, the dustproof position is a position directly above the air inlet 111, and when the wall-mounted air conditioning indoor unit needs to be dustproof, the first wind deflector 13 and the second wind deflector 14 can both rotate to the dustproof position (as shown in fig. 1), so as to ensure the dustproof effect to the maximum extent.

In addition, in the preferred embodiment, the number of the wind blocking positions is plural, and by the above-described structural arrangement, the first wind blocking plate 13 and the second wind blocking plate 14 can realize three wind blocking modes:

the first wind shielding mode is as follows: the wind shielding section 131 of the first wind shielding plate 13 is rotated to the vicinity of the wind outlet 112 alone, and in this case, the wind shielding section 131 of the first wind shielding plate 13 is engaged with the wind deflector 12 alone so as to be able to disperse the wind flow with the first wind shielding strength.

The second wind shielding mode is as follows: the wind shielding section 141 of the second wind shielding plate 14 rotates to the vicinity of the wind outlet 112, in this case, the wind shielding section 141 of the second wind shielding plate 14 cooperates with the wind guiding plate 12 alone, so as to scatter the wind flow with the second wind shielding strength.

The third wind shielding mode is as follows: the wind shielding section 131 of the first wind shielding plate 13 and the wind shielding section 141 of the second wind shielding plate 14 can be simultaneously rotated to the vicinity of the wind outlet 112, and in this case, the wind shielding section 131 of the first wind shielding plate 13 and the wind shielding section 141 of the second wind shielding plate 14 are engaged with the wind shielding plate 12 so that the wind stream can be dispersed with the third wind shielding strength.

Based on above-mentioned three kinds of modes of keeping out the wind, first deep bead 13 and second deep bead 14 can break up the air-out air current with at least three kinds of different intensities of keeping out the wind, so that wall-hanging air conditioning indoor set can adjust different schemes of keeping out the wind by oneself according to user's in-service use demand to when avoiding directly blowing the problem, can also laminate user's air supply demand to the at utmost, and then effectively improve the comfort level of air supply.

As a preferable shape arrangement, the wind shielding section 131 of the first wind shielding plate 13 and the wind shielding section 141 of the second wind shielding plate 14 are arranged in an arc-shaped plate-shaped structure with a convex middle portion along the circumferential direction. Specifically, the wind shielding section 131 of the first wind shielding plate 13 and the wind shielding section 141 of the second wind shielding plate 14 are integrally rectangular plates, and the rectangular plates are bent along the width direction, so that the rectangular plates form an arc-shaped plate-shaped structure with high middle and low two sides along the circumferential direction, and the middle part of the rectangular plates is protruded outwards, so that a columnar groove with an arched section is formed in the rectangular plate-shaped structure, and then drainage is performed better, so that the scattering effect is effectively improved.
