And an air outlet duct disposed in the casing 150 and extending from the downstream of the cross flow fan 110 to the casing 150, wherein two air outlets disposed at intervals and a partition wall 154 disposed between the two air outlets are formed at a position of the casing 150 opposite to the air outlet duct.

Each of the air outlets may extend in a lateral direction of the cabinet 150. The two air outlets are respectively a first air outlet 152 located on the bottom plate of the casing 150 and a second air outlet 153 located at the bottom of the front plate of the casing 150. That is, the first outlet 152 faces the lower side of the housing 150, the second outlet 153 faces the front side of the housing 150, and the second outlet 153 is close to the first outlet 152.

That is, the heat-exchange air flow blown out from the first outlet 152 may be blown toward the lower side of the cabinet 150, and the heat-exchange air flow blown out from the second outlet 153 may be blown toward the front side of the cabinet 150. By improving the number and the positions of the air outlets, the indoor unit 10 of the present embodiment can form a lower air outlet region and a front air outlet region below and in front of the casing 150, respectively. The indoor unit 10 having two air outlet regions can blow the heat exchange air downward and forward, so that the heat exchange air can be blown in different directions, and the adjustment range of the indoor unit 10 to the air outlet direction is enlarged.

The air outlet may be rectangular in shape, and in alternative embodiments, the air outlet may also be circular, or any other shape.

The outlet duct extends from downstream of the cross flow fan 110 to the front downward to the casing 150, wherein "downstream of the cross flow fan 110" is with respect to the flow path of the heat exchange air flow, and the outlet duct is located downstream of the cross flow fan 110 in the extending direction of the flow path of the heat exchange air flow.

The two air outlets are opposite to the air outlet duct. The air outlet duct may be a passage communicated between the air outlet end of the cross flow fan 110 and the two air outlets, and the heat exchange air flows to the air outlet along the air outlet duct under the action of the cross flow fan 110.

The partition wall 154 may be located at a portion where the front and bottom panels of the cabinet 150 meet and between the two end panels of the cabinet 150. By adjusting the width of the partition wall 154, the first outlet 152 can be adjacent to the second outlet 153.

The lower duct wall 130 extends from the bottom rear side of the cross flow fan 110 to the front lower side to the periphery of the first air outlet 152 away from the partition wall 154. The periphery of the first air outlet 152 away from the partition wall 154 refers to a periphery of the first air outlet 152 away from the partition wall 154, which is parallel to the lateral extension direction of the casing 150. And an upper duct wall 120 extending forward from the bottom front side of the cross flow fan 110 to the periphery of the second outlet port 153 away from the partition wall 154. The periphery of the second outlet 153 away from the partition wall 154 refers to a periphery of the second outlet 153 away from the partition wall 154, of two peripheries of the second outlet 153 parallel to the lateral extension direction of the casing 150. That is, the lower duct wall 130 and the upper duct wall 120 enclose the outlet duct. The upper duct wall 120 may be extended forward in the front-rear direction of the casing 150, starting at the downstream side of the cross flow fan 110. The lower duct wall 130 may be provided to extend forward and downward in the front-rear direction and the longitudinal direction of the cabinet 150.

The directions of "front", "back", "transverse", "longitudinal", and the like are relative to the actual use state of the indoor unit 10, the longitudinal direction may be a substantially vertical direction, and the front-back extending direction and the transverse extending direction of the casing are both parallel to the horizontal plane.

The cross-flow fan 110 causes the heat exchange air flow to enter the outlet duct from a portion between one end of the lower duct wall 130 close to the cross-flow fan 110 and one end of the upper duct wall 120 close to the cross-flow fan 110.

The rotary air duct assembly 140 is disposed in the air outlet duct, and has a pivot 141 disposed on the partition wall 154 and an air duct plate 142 connected to the pivot 141. The air duct plate 142 is configured to controllably rotate around the pivot shaft 141 to guide the heat exchange air flow in the air outlet duct to an air outlet.

In the indoor unit 10 of this embodiment, the air duct plate 142 is controlled to rotate, so that the heat exchange airflow in the air outlet duct can be guided to the first air outlet 152 or the second air outlet 153, and the heat exchange airflow can be blown out from any one of the air outlets, so that the indoor unit 10 has two different air outlet modes, and therefore the indoor unit 10 can only blow the heat exchange airflow outwards from the set air outlet along the set direction according to the user requirement, and the user experience is improved.

The pivot shaft 141 may extend in a transverse direction of the casing 150 and is fixed to a side of the partition wall 154 facing the air outlet duct. The length of the pivot shaft 141 in the lateral extension direction of the casing 150 may be the same as the length of the partition wall 154 in the lateral extension direction of the casing 150, or may be slightly smaller than the length of the partition wall 154 in the lateral extension direction of the casing 150.

The air duct plate 142 may have a rectangular plate shape. The length of the air duct plate 142 may be the same as the length of the pivot shaft 141 along the transverse extending direction of the casing 150, and the width of the air duct plate 142 may be set according to actual requirements, so that the air duct plate 142 may flexibly rotate in the air outlet duct without mechanical interference, and may overlap with a corresponding portion of the air outlet duct, thereby generating different air guiding effects. In the width direction of the air duct plate 142, it has one end connected to the pivot shaft 141, and one end distant from the pivot shaft 141. In some alternative embodiments, the shape of the air duct plate 142 may be set according to the shape of the air outlet duct, and the air duct plate 142 may also be a special shape having a specific shape, which is not specifically limited herein.

The duct plate 142 has a first operative position rotated to overlap the lower duct wall 130 and a second operative position rotated to overlap the upper duct wall 120. The duct plate 142 is configured to communicate the air outlet duct with the second air outlet 153 when in the first working position, and is further configured to communicate the air outlet duct with the first air outlet 152 when in the second working position.

When the air duct plate 142 is located at the first working position, the passage between the heat exchange airflow and the first air outlet 152 is blocked, and an air outlet passage for guiding the heat exchange airflow to the second air outlet 153 is enclosed between the air duct plate and the upper air duct wall 120. When the air duct plate 142 is located at the second working position, the passage between the heat exchange airflow and the second air outlet 153 is blocked, and an air outlet passage for guiding the heat exchange airflow to the first air outlet 152 is enclosed between the air duct plate and the lower air duct wall 130.

By changing the working position of the air duct plate 142, the heat exchange airflow in the air outlet duct can only be blown to one air outlet under the action of the air duct plate 142, so that almost all the heat exchange airflow can be blown out from the set air outlet, the air output of the air outlet is increased, and the indoor unit 10 has a high heat exchange effect in any air outlet mode.

When the indoor unit 10 is in the cooling mode and the air duct plate 142 is located at the first working position, the heat-exchange air flow is blown forward from the second air outlet 153, the blowing area of the heat-exchange air flow is not the user activity area, and the cool air does not blow directly to the user. When the indoor unit 10 is in the heating mode, and the air duct plate 142 is located at the second working position, the heat exchange airflow is blown out downwards from the first air outlet 152, and this blowing mode can promote the heat exchange airflow with higher temperature to quickly fill the whole active area where the user is located, so that the heating efficiency is high, the temperature is uniform, and the user experience is improved. By additionally providing the air outlet and adjusting the flow path of the heat exchange air flow by using the air duct plate 142, the indoor unit 10 of the present embodiment has a suitable air supply angle in both the heating mode and the cooling mode.

The lower duct wall 130 is provided with a first engaging groove 121. The first locking groove 121 has a shape matched with a shape of an end of the air duct plate 142 away from the pivot shaft 141, and is configured to overlap with an end of the air duct plate 142 away from the pivot shaft 141, so that the air duct plate 142 is located at the first working position. The height of the position of the first engaging groove 121 may be substantially the same as the height of the position of the pivot shaft 141, for example, the height of the first engaging groove 121 may be lower than or equal to the height of the pivot shaft 141, or may be slightly higher than the height of the pivot shaft 141. When the height of the first engaging groove 121 is slightly lower than or equal to the height of the pivot shaft, the air duct plate 142 and the upstream portion of the first engaging groove 121 of the lower air duct wall 130 together form a smooth passage extending to the second air outlet 153 and close to the periphery of the partition wall 154, so as to reduce or prevent the shielding phenomenon of the air duct plate 142 on the heat exchange air flow, and reduce or prevent the noise generated when the heat exchange air flow flows.

Here, the "height" is relative to the actual usage state of the indoor unit 10, and may be understood as a vertical height position.

The upper duct wall 120 is provided with a second engaging groove 131. The second locking groove 131 has a shape matching the shape of the end of the air duct plate 142 away from the pivot 141, and is configured to overlap the end of the air duct plate 142 away from the pivot 141, so that the air duct plate 142 is located at the second working position. The second locking groove 131 is disposed at an end of the upper duct wall 120 close to the cross flow fan 110.

The distance between the first engaging groove 121 and the pivot shaft 141 is adapted to the width of the air duct plate 142, so that when the air duct plate 142 rotates to the first engaging groove 121, the lower air duct wall 130 is overlapped with the air duct plate 142 by the first engaging groove 121, and the air duct plate 142 stops rotating and stays at the first working position. The distance between the second engaging groove 131 and the pivot shaft 141 may be adapted to the width of the air duct plate 142, so that when the air duct plate 142 rotates to the second engaging groove 131, the upper air duct wall 120 is overlapped with the air duct plate 142 by the second engaging groove 131, and the air duct plate 142 stops rotating and stays at the second working position.

A water receiving tray for receiving the condensed water in the heat exchange cavity is formed on one side of the upper air duct wall 120 back to the air outlet duct. The side of the upper duct wall 120 facing away from the outlet duct, i.e. the top of the upper duct wall 120. In the present embodiment, the upper duct wall 120 is located below the second heat exchanging part, and the top of the upper duct wall 120 may face the second heat exchanger 180. Because the upper duct wall 120 is disposed along the front-rear extension direction of the casing 150, the wall surface of the upper duct wall 120 is relatively flat, and the top of the upper duct wall 120 can serve as a water pan for receiving the condensed water generated on the heat exchanger 180, thereby simplifying the internal structure of the indoor unit 10 and saving the manufacturing cost.

In some optional embodiments, the indoor unit 10 may further include two locking assemblies respectively configured to lock the air duct plate 142 when the air duct plate 142 is located at the first working position and the second working position, so as to reduce or prevent noise or turbulence generated by displacement of the air duct plate 142 due to airflow impact, and improve stability of an air outlet structure of the indoor unit 10.

The first air guiding assembly may include a first air guiding plate 160, a first rotating shaft, and a first driving mechanism. The first air guiding plate 160 is disposed at the first air outlet 152, and configured to close the first air outlet 152 when the air duct plate 142 overlaps the lower air duct wall 130, and open the first air outlet 152 when the air duct plate 142 overlaps the upper air duct wall 120.

The shape of the first air guiding plate 160 can be matched with the shape of the first air outlet 152, so as to shield the first air outlet 152 when the first air outlet 152 has no air outlet requirement. The first driving mechanism is configured to drive the first air guiding plate 160 to rotate around the first rotation axis in a controlled manner to open or shield the first air outlet 152, or may drive the first air guiding plate 160 to continuously swing around the first rotation axis to achieve a wind sweeping function.

The first shaft may be disposed on the partition wall 154 and spaced apart from the pivot shaft 141 of the rotary air duct assembly 140.

In the heating mode, the air duct plate 142 may be located at the second working position, and the first air deflector 160 may be rotated to the vertical position, so that the heat exchange air flow can be blown downward in the vertical direction, and the rate of the heat exchange air flow reaching the user activity space is increased, thereby improving the heating efficiency. The vertical position refers to a position where the plane of the first air guiding plate 160 is parallel to the vertical plane.

The second air guiding assembly may include a second air guiding plate 170, a second rotating shaft, and a second driving mechanism. The second air guiding assembly is disposed at the second air outlet 153, and is configured to close the second air outlet 153 when the air duct plate 142 overlaps the upper air duct wall 120, and open the second air outlet 153 when the air duct plate 142 overlaps the lower air duct wall 130.

The shape of the second air guiding plate 170 may be adapted to the shape of the second air outlet 153, so as to shield the second air outlet 153 when the second air outlet 153 has no air outlet requirement. The second driving mechanism is configured to drive the second air guiding plate 170 to rotate around the second rotating shaft in a controlled manner so as to open or shield the second air outlet 153, or the second air guiding plate 170 can be driven to continuously swing around the second rotating shaft so as to realize a wind sweeping function. The second shaft may be disposed on the upper duct wall 120 and located at a position of the upper duct wall 120 close to the casing 150.

In the cooling mode, the air duct plate 142 may be located at the first working position, and the second air deflector 170 may rotate to the horizontal position, so that the heat exchange airflow may be blown forward along the horizontal direction, thereby reducing or avoiding the problem of downward blowing and direct blowing of the heat exchange airflow, and improving the comfort of the air supply. The horizontal position is a position where the plane of the second wind guide plate 170 is parallel to the horizontal plane.
