As shown in fig. 1-6, an indoor unit includes a casing 100, a fan assembly, and an air duct 200. Wherein, an air inlet 111 and an air outlet 112 are disposed on the same side plate of the casing 100; the fan assembly is disposed in the casing 100; the air duct 200 is disposed in the casing 100, and has one end connected to the fan assembly and the other end connected to the air outlet 112, so as to guide the air discharged from the fan assembly to the air outlet 112; and the wind outlet direction of the wind outlet 112 is inclined towards the wind inlet direction far away from the wind inlet 111 under the guidance of the wind tunnel 200.

By adopting the indoor unit provided by the embodiment of the disclosure, the air inlet 111 and the air outlet 112 are arranged on the same side plate, and the air outlet direction of the air outlet 112 is guided to incline towards the air inlet direction far away from the air inlet 111 by the air duct 200, so that the air inlet direction and the air outlet direction on the same side plate are designed in a non-parallel manner, the phenomenon of air duct short circuit caused by mutual interference of air inlet and air outlet is avoided, and the stability of the indoor unit under the refrigeration or heating working condition is improved.

Optionally, an angle α of the wind outlet direction of the wind outlet 112 inclining towards the wind inlet direction away from the wind inlet 111 is greater than or equal to 30 ° and less than or equal to 45 °.

Illustratively, one air inlet 111 and one air outlet 112 are disposed on the front side plate 110 of the cabinet 100, and the air outlet 112 is located at one side of the air outlet 112. The air inlet direction of the air inlet 111 is perpendicular to the plate surface of the front side plate 110, the air outlet direction of the air outlet 112 is inclined to the plate surface of the front side plate 110 under the guidance of the air duct 200, and the inclination angle of the air outlet direction of the air outlet 112 towards the air inlet direction far away from the air inlet 111 is alpha, which is greater than or equal to 30 degrees and less than or equal to 45 degrees. For example, α may be set to any one of 30 °, 33 °, 35 °, 36 °, 38 °, 40 °, 42 °, 43 °, or 45 °.

Optionally, one air inlet 111 and two air outlets 112 are disposed on the same side plate of the casing 100, and the two air outlets 112 are respectively located at two sides of the air inlet 111; the air outlet directions of the two air outlets 112 are inclined at the same angle toward the air inlet direction away from the air inlet 111. Thus, the air outlet directions of the two air outlets 112 are symmetrically located at two sides of the air inlet direction of the air inlet 111, and the wind feeling of the user is comfortable.

Illustratively, as shown in fig. 3, one air inlet 111 and two air outlets 112 are disposed on the front side plate 110 of the cabinet 100, and the two air outlets 112 are disposed on the left and right sides of the air outlets 112. The fan assembly includes two centrifugal fans 210, and the two centrifugal fans 210 correspond to the two air outlets 112, respectively. Two air ducts 200 are disposed in the casing 100 and respectively communicate with the corresponding centrifugal fan 210 and the air outlet 112. Under the guiding action of the two air ducts 200, the air outlet directions of the two air outlets 112 are symmetrically located at the left and right sides of the air inlet direction of the air inlet 111, so that the inclination angle α of the air outlet direction of each air outlet 112 towards the air inlet direction far away from the air inlet 111 is the same. For example, the angles a of inclination are both 30 °, or both 40 °, or both 45 °.

Optionally, one air inlet 111 and two air outlets 112 are disposed on the same side plate of the casing 100, and the two air outlets 112 are respectively located at two sides of the air inlet 111; the air outlet directions of the two air outlets 112 are different from the air inlet direction away from the air inlet 111 by the inclination angle α. Therefore, the air outlet direction of the air outlet 112 can be adjusted according to the layout of the decoration space of the indoor unit, so that the decoration requirement can be met, the phenomenon of short circuit of an air duct can be avoided, and the applicability is high.

Illustratively, one air inlet 111 and two air outlets 112 are disposed on the front side plate 110 of the cabinet 100, and the two air outlets 112 are disposed on the left and right sides of the air outlets 112. The fan assembly includes two centrifugal fans 210, and the two centrifugal fans 210 correspond to the two air outlets 112, respectively. Two air ducts 200 are disposed in the casing 100 and respectively communicate with the corresponding centrifugal fan 210 and the air outlet 112. Under the guiding action of the two air ducts 200, the air outlet directions of the two air outlets 112 are both inclined towards the air inlet direction far away from the air inlet 111, and the inclination angles α of the air outlet direction of each air outlet 112 towards the air inlet direction far away from the air inlet 111 are different.

Optionally, a temperature sensor is disposed at the air inlet 111 of the casing 100, and the temperature sensor is used to detect the temperature of the air entering the casing 100 from the air inlet 111. Therefore, the temperature sensor is beneficial to technicians to adjust the angle between the air outlet direction and the air inlet direction in the production and manufacturing stage of the indoor unit.

For example, in a preset experimental refrigeration working condition of the indoor unit, the temperature of air entering the casing 100 from the air inlet 111 is 31 ℃, and the temperature of air blown into the indoor unit from the air outlet 112 after heat exchange is 21 ℃. If the temperature sensor detects that the temperature of the air entering the casing 100 from the air inlet 111 is 25 ℃, an air duct short circuit occurs, and a large amount of cold air blown out from the air outlet 112 directly returns to the casing 100 from the air inlet 111 without being blown into the room for cooling. At this time, the technician may increase the angle α of the air outlet direction of the air outlet 112 inclining towards the air inlet direction far away from the air inlet 111 according to the actual situation, so as to further avoid the mutual interference between the air outlet and the air inlet.

Because the axis of the linear pipe section is staggered with the air inlet direction of the air inlet 111, and the air is guided to the air inlet direction far away from the air inlet 111, the air outlet direction of the air outlet 112 is inclined towards the air inlet direction far away from the air inlet 111. The duct segment at the second end of the air chute 200, and the duct segment between the ends of the air chute 200, may be curved, such that the effect of the air chute 200 on the layout of other components may be reduced by the combination of curved and straight duct segments.
