Since the ducted air conditioner is placed in a corner or closet, the depth in the front-rear direction has a greater influence than the length in the up-down direction. In view of this, 0 ° < α+.ltoreq.45° in the present application, so that, on the one hand, it is possible to ensure that the depth of the housing 1 in the front-rear direction is as small as possible without excessively increasing the length in the up-down direction; on the other hand, the condensed water of the heat exchanger 41 can smoothly flow into the water receiving tray 45.

In one embodiment, referring to fig. 2 to 4, the axis of the blower 3 extends in the front-rear direction. That is, the rotational axis of the rotor extends in the front-rear direction. The larger the diameter of the casing 31 is, the larger the diameter of the wind wheel can be and the larger the air volume of the fan 3 is, the smaller the diameter of the casing 31 is, the smaller the diameter of the wind wheel and the smaller the air volume of the fan 3 can directly affect the performance, however, if the axis of the casing 31 is arranged along the left-right direction, the diameter of the casing 31 can affect the size of the casing 1 along the front-back direction, so that the depth of the casing 1 along the front-back direction is deeper, and therefore, the axis of the fan 3 extends along the front-back direction, so that the diameter of the wind wheel and the casing 31 can be sufficiently large without increasing the depth of the casing 1 along the front-back direction, and the depth of the air duct machine along the front-back direction can be thinner.

In one embodiment, the housing 31 is formed with an air inlet on at least one side in the front-rear direction, and an air outlet is formed on the circumferential surface of the housing 31. Thus, the wind wheel can be a centrifugal wind wheel, and the wind quantity is large.

For example, referring to fig. 5, in one embodiment, the housing 31 may be a volute structure,

in one embodiment, the middle partition plate 5 is formed with a vent penetrating through the upper and lower end surfaces thereof, the air flow outlet is in butt joint communication with the vent, and the vent faces the air outlet 1b. In this way, the air flow from the air flow outlet is blown toward the air outlet 1b through the vent.

The air flow outlet is in butt joint communication with the vent, which means that: the flow cross-sectional area of the air outlet is substantially equal to the flow cross-sectional area of the vent, and the projection of the air outlet onto the baffle plate 5 overlaps the vent.

In an embodiment, referring to fig. 1 to 3, an air outlet 1b is formed on an upper end surface of a housing 1, and an air inlet 1a is formed on a front end surface of the housing 1 and/or a lower end surface of the housing 1. For example, the air intake port 1a may be formed only in the front end surface of the housing 1. For another example, the air intake port 1a may be formed only on the lower end surface of the housing 1. For another example, the air inlet 1a may be formed in both the front end surface of the housing 1 and the lower end surface of the housing 1. Indoor air flow enters the shell 1 through the air inlet 1a, flows through the heat exchanger 41 and then flows out through the air outlet 1b. The indoor air flows through the filter screen and the heat exchanger 41, and then sequentially flows through the air inlet, the air outlet, the ventilation opening and the air outlet 1b.

In an embodiment, referring to fig. 1 and 7, at least part of one side wall of the housing 1 is configured as a detachable shielding plate 101, a portion where the shielding plate 101 is located is detached to form a first air opening, the other side wall of the chassis 11 is formed with a second air opening, the shielding plate 101 can shield at least part of one of the first air opening and the second air opening, and the other of the first air opening and the second air opening is the air inlet 1a. So designed, at least one of the first and second air vents may be selected as the air intake 1a according to the need.

For example, the housing 1 may have a hexahedral structure, that is, the housing 1 has six sidewalls. In one embodiment, referring to fig. 1, the first tuyere may be formed at a front sidewall of the housing 1. For example, the front cover plate 12 covers an upper portion of the front opening of the chassis 11, and a lower portion of the front opening is the first tuyere.

Illustratively, in an embodiment, the second tuyere may be formed at a lower sidewall of the casing 1.

Illustratively, in one embodiment, both side surfaces of the heat exchanging device 4 along the left-right direction are in sealing abutment with the inner surface of the housing 1 along the left-right direction, the front cover plate 12 is in sealing abutment with the connecting piece 42, and the bottom surface of the water pan 45 is in sealing abutment with the inner bottom surface of the housing 1. Thus, the indoor air flow from the air inlet 1a basically flows through the heat exchanger 41, and the heat exchange effect is good. The first tuyere is located below the connection 42. The second tuyere is located in front of the water tray 45.

The foregoing is merely specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the present application, and the changes and substitutions are intended to be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
