In the embodiment of the present invention, as shown in FIG. 1 and FIG. 2 , the wall-mounted air conditioner indoor unit 10 includes a casing 12 , a heat exchanger 14 and a fan wheel 16 arranged in the casing 12 . An air inlet 122 and an air outlet 124 are formed on the casing 12 . The outside air enters through the air inlet 122 , and after heat exchange through the heat exchanger 14 , is blown out from the air outlet 124 by the drive of the wind wheel 16 .

The rear heat exchange part 144 is adjacent to the installation wall. The radiator 14 is located on the outer circumference of the rotor 16 , and the flare of the radiator 14 faces the rotor 16 .

In this embodiment, the wall-mounted air conditioner indoor unit 10 further includes an air guide assembly 18 , and the air guide assembly 18 is disposed at the air outlet 124 for adjusting the air outlet direction of the air outlet 124 . In one embodiment, the air guide assembly 18 can sweep the air up and down to adjust the air outlet direction of the air outlet 124 in the up and down direction, and can also sweep the air left and right to adjust the air outlet direction of the air outlet 124 in the left and right direction.

It should be noted that, in this embodiment, the up and down, left and right, and front and rear directions refer to the directions determined when the wall-mounted air conditioner indoor unit 10 is hung on the wall and the user is facing the wall-mounted air conditioner indoor unit 10 .

In this embodiment, as shown in FIGS. 2-4 , the casing 12 includes a casing body 200 and a panel 300 . The air inlet 122 and the air outlet 124 are formed on the casing body 200 . The panel 300 includes a main body portion 310 and an inner buckle portion 320 . The main body portion 310 is disposed on the front side of the casing body 200 and above the air outlet 124 . The inner buckle portion 320 is disposed on the main body portion 310 , and a side of the inner buckle portion 320 away from the main body portion 310 extends into the air outlet 124 . And the upper surface of the inner buckle portion 320 is buckled with the inner wall surface of the air outlet 124 . The lower surface of the inner buckle portion 320 is an anti-condensation inclined surface 222 . On the air flow path from the air inlet 122 to the air outlet 124 , the anti-condensation inclined surface 322 is inclined outward.

In the above-mentioned wall-mounted air conditioner indoor unit 10, the upper surface of the inner buckle portion 320 is buckled with the inner wall surface of the air outlet 124, and the inner buckle portion 320 makes the panel 300 and the shell body 200 relatively sealed at the air outlet 124, and the inner buckle portion 320 The gap between the main body 310 and the case body 200 can be shielded, and when the air flows on the air flow path from the air inlet 122 to the air outlet 124 , the inner buckle part 320 can block the air flow to the space between the main body 310 and the case body 200 . Therefore, the condensation phenomenon inside the wall-mounted air conditioner indoor unit 10 can be effectively avoided.

Moreover, the inner buckle portion 320 extends into the air outlet 124 from the side away from the main body portion 310 . After the upper surface of the inner buckle portion 320 is buckled with the inner wall surface of the air outlet 124 , the lower surface of the inner buckle portion 320 can serve as the inner surface of the air outlet 124 . On the wall surface (that is, the inner wall surface of the air duct 400 ), the lower surface of the inner buckle portion 320 is set as an outwardly inclined anti-condensation slope 322, which can prevent the cold and hot air from converging on the lower surface of the inner buckle portion 320 to form condensation. , so that condensation phenomenon outside the panel 300 can be effectively avoided.

In this embodiment, the inclination angle β of the anti-condensation inclined surface 322 inclined outward is 5-15°. Since the lower surface of the inner buckle portion 320 is the inner wall surface of the air outlet 124, if the inclination angle β is too large, the opening of the air outlet 124 will be too large, which will affect the air outlet of the entire wall-mounted air conditioner indoor unit 10, and needs to be redesigned and adjusted. If the inclination angle β is too small, the effect of preventing cold and hot air from converging on the lower surface of the inner buckle portion 320 to form condensation is limited. In order not to greatly affect the overall air outlet and to obtain a better anti-condensation effect, set the inclination angle β to 5-15°. It should be noted that the inclination angle β refers to the included angle between the anti-condensation slope 322 and the horizontal plane X.

Specifically, in this embodiment, the inclination angle β at which the anti-condensation inclined surface 322 is inclined outward is 7-9°. In this way, it can better take into account the effects of air outlet and anti-condensation. Preferably, in this embodiment, the inclination angle β at which the anti-condensation inclined surface 322 is inclined outward is 8°.

In this embodiment, a rounded corner 324 is provided between the front side surface of the main body portion 310 and the anti-condensation inclined surface 322 . The rounded corners 324 can further prevent the cold and hot air from converging on the lower surface of the inner buckle portion 320 to form condensation, so as to effectively avoid condensation outside the panel 300 .

In this embodiment, the inner wall surface of the air outlet 124 includes a buckling area 1242 , and the buckling area 1242 is parallel to the horizontal plane X. As shown in FIG.

And on the air flow path from the air inlet 122 to the air outlet 124 , the distance between the buckling inclined surface 326 and the buckling region 1242 gradually decreases, that is, the inner side of the upper surface of the inner buckle portion 320 slopes downward.

When the upper surface of the inner buckle portion 320 is fastened with the inner wall surface of the air outlet 124, considering the feasibility of assembly, it is necessary to reserve a sufficient assembly gap, which will cause the upper surface of the inner buckle portion 320 to be engaged with the inner wall surface of the air outlet 124. There are gaps in between. In this embodiment, the buckling area 1242 is set to be parallel to the horizontal plane X, the upper surface of the inner buckling portion 320 is set as the buckling slope 326, and the inner side of the upper surface of the inner buckling portion 320 is set to be inclined downward, which is convenient for assembly. The gap is convenient for making the outer side of the buckle region 1242 collide with the buckle slope 326 , so as to better prevent airflow from entering between the main body 310 and the shell body 200 from the gap between the buckle region 1242 and the buckle slope 326 .

In this embodiment, the inclination angle of the buckling inclined surface 326 is smaller than the inclination angle of the anti-condensation inclined surface 322 .

A second block 212 is inserted into each of the first card slots 420 , and a first block 410 is inserted into each of the second card slots 214 . That is, the outer wall of the air duct 400 close to the main body portion 310 meshes with the inner wall of the housing structure 210 in a manner similar to the meshing of two gears to form a labyrinth tight fit structure, so that the air duct 400 is close to the outer wall of the main body portion 310 and the housing. The inner wall of the structure 210 is sealed and connected to prevent the airflow blown from the air outlet 124 from entering the wall-mounted air conditioner indoor unit 10 through the gap between the outer wall of the air duct 400 near the main body 310 and the inner wall of the housing structure 210 .
