In addition, the layout of the upper duct assembly 50, the lower duct assembly 60 and the evaporator 40 is simple in structure, convenient to install, and capable of reducing the placement area of the indoor unit 1.
As shown in fig. 1 to 4, according to some embodiments of the present invention, the housing 10 may be formed as a square body, and the housing 10 is disposed in a flat shape in a front-rear direction, the evaporator 40 is formed as a straight plate extending in a vertical direction, and the wind wheels 680 of the upper air duct assembly 50 and the lower air duct assembly 60 are cross-flow wind wheels disposed in parallel with the evaporator 40.
It will be appreciated that, as shown in fig. 1-4, the shape of the housing 10 may be approximately rectangular, the longitudinal direction of the housing 10 may be the up-down direction shown in fig. 1, the thickness direction of the housing 10 may be the front-back direction shown in fig. 1, and the housing 10 may be flat in the front-back direction.

The cross flow wind wheel pair has natural advantages in realizing flattening of the indoor unit, because the internal flow characteristics of the cross flow wind wheel are as follows: the fluid is injected in the radial direction and flows out in the radial direction, and flows through the fan blades twice. The cross flow fan has compact structure and small size, and the length of the impeller can be freely selected according to the air quantity requirement. Therefore, the cross-flow wind wheels are arranged at the upper end and the lower end of the evaporator 40, so that the cross-flow wind wheels can be arranged along the left-right direction of the air conditioner outdoor unit 100, the front-back direction of the cross-flow wind wheels is very small, and meanwhile, the requirements of the air outlet direction can be met, and the indoor unit can realize the flattening design.
Since the thickness of the casing 10 in the front-rear direction is reduced, the area occupied by the placement of the air conditioning indoor unit 1 can be reduced. The flat air-conditioning indoor unit 1 is hung on a wall surface, the air-conditioning indoor unit 1 is similar to ornaments such as clocks and watches, picture frames and the like in vision, and the air-conditioning indoor unit 1 can give the illusion of the wall surface even under reasonable arrangement, so that the air-conditioning indoor unit 1 is beneficial to improving indoor opening feeling.

In some embodiments of the present invention, as shown in fig. 4, the evaporator 40 is disposed obliquely forward in a downward direction (downward as shown in fig. 4), and an angle between the evaporator 40 and the vertical plane is 30 degrees or less. It will be appreciated that the length extending direction of the evaporator 40 may form an acute angle with the length extending direction of the housing 10, and the acute angle may be in a range of zero degrees or more and thirty degrees or less, where an end of the evaporator 40 near the top of the housing 10 is near the rear side of the housing 10 (as shown in fig. 4, and a rear end of the evaporator 40 near the bottom of the housing 10 is near the front side of the housing 10 (as shown in fig. 4, front). Thereby, the evaporator 40 can be easily fixed to the housing 10. And the inclined arrangement forms a certain heat exchange space between the two sides of the evaporator 40 and the shell 10, which is beneficial to improving the heat exchange efficiency.
In some examples of the present invention, the thickness of the housing 10 may be 120-180mm, i.e., the thickness of the housing 10 in the front-rear direction may range from 120mm to 180mm. Therefore, the occupied area for placing the air conditioner indoor unit 1 can be reduced, the flattening design of the air conditioner indoor unit 1 is facilitated, and the storage and placement of the air conditioner indoor unit 100 are facilitated.
