an upper air supply member including an upper air supply fan configured to draw in ambient air from an environment surrounding the air inlet and cause it to flow through the heat exchanger towards the upper air outlet;

the upper air guide component is positioned behind the upper air outlet and comprises at least two air guide rings which are provided with front and rear openings and are communicated in the middle, the air guide rings are sequentially arranged in the front and rear direction to form a communicated air channel which penetrates through the air guide rings, a jet opening is formed between every two adjacent air guide rings, and the jet opening is configured to guide heat exchange airflow blown out by the upper air supply fan to the communicated air channel and eject the airflow forwards so as to drive the air in the communicated air channel to be sent to the upper air outlet forwards.

6. The indoor unit according to claim 5, wherein the indoor unit further comprises a guide member for guiding the air flow in the air flow direction

And a natural air draught opening is formed in the area, opposite to the through air channel, of the rear wall of the shell, so that when the jet opening sprays the air flow in the through air channel forwards, the ambient air around the natural air draught opening is promoted to flow forwards to enter the through air channel and be mixed with the heat exchange air flow blown out from the jet opening.

7. The indoor unit according to claim 5, wherein the indoor unit further comprises a guide member for guiding the air flow in the air flow direction

The number of the air guide rings is at least four, wherein two air guide rings positioned in the middle are marked as two middle air guide rings;

the indoor unit further comprises a third driving mechanism which is connected with the two middle air guide rings and configured to enable the two middle air guide rings to move so as to change the air supply direction of the two middle air guide rings.

8. The indoor unit of claim 7, wherein the upper air guide member further comprises:

the mounting plate is positioned in front of the air guide ring at the foremost side and is provided with an opening communicated with the through air duct;

the third drive mechanism includes:

a third motor disposed below the front side of the mounting plate and having an output shaft parallel to the height direction of the housing;

the driving box is positioned below the air guide ring, the front end of the driving box is arranged on the mounting plate, the rear end of the driving box is arranged on the air guide ring behind the rear middle air guide ring, and a first fixing shaft which is parallel to an output shaft of the third motor and extends upwards is formed in the driving box;

the first crank is positioned in the driving box, is rotatably connected with the first fixed shaft, and is provided with a first connecting shaft which is parallel to the output shaft of the third motor and extends upwards and a second connecting shaft which extends downwards, and the first connecting shaft penetrates through the driving box and is fixedly connected with the lower end of the middle air guide ring positioned in front;

one end of the second crank is fixedly connected with an output shaft of the third motor, and a rotating shaft which is parallel to the output shaft of the third motor and extends upwards is formed at the other end of the second crank; one end of the driving connecting rod is connected with the rotating shaft of the second crank, and the other end of the driving connecting rod penetrates through the driving box to be connected with the second connecting shaft so as to drive the middle air guide ring positioned in front to rotate leftwards or rightwards; and

the balance connecting rods extend horizontally and are positioned above the two middle air guide rings, and two ends of each balance connecting rod are respectively and rotatably connected with the upper ends of the two middle air guide rings so as to drive the middle air guide ring positioned at the rear to rotate synchronously when the middle air guide ring positioned at the front rotates.

9. The indoor unit according to claim 8, wherein the indoor unit further comprises a cover for covering the indoor unit

The third drive mechanism further includes:

the supporting box is positioned above the air guide ring, the front end of the supporting box is arranged on the mounting plate, and the rear end of the supporting box is arranged on the air guide ring behind the rear middle air guide ring;

the third crank is positioned in the supporting box and is provided with a third connecting shaft which is parallel to and opposite to the first connecting shaft, and the third connecting shaft penetrates through the supporting box and extends downwards to be fixedly connected with the upper end of the middle air guide ring positioned in front;

the number of the balance connecting rods is two, and the two balance connecting rods are located on the two transverse sides of the support box in the transverse direction.

10. The indoor unit according to claim 9, wherein the indoor unit further comprises a cover for covering the indoor unit
