Because the diversion air duct has the diversion air outlet 15b matched with the corresponding air outlet rotation path on the front panel 12, obviously, the size of the diversion air outlet 15b of the diversion air duct is larger than that of the corresponding air outlet (upper air outlet 12a, lower air outlet 12b) on the front panel 12, an arc wind shield 12c is respectively formed on the periphery of the upper air outlet 12a and the lower air outlet 12b, and the arc wind shield 12c is used for blocking the air flow from flowing to one side of the arc wind shield 12c in the diversion air duct, so that the air flow is intensively blown out forwards through the corresponding air outlet by the diversion air outlet 15b of the diversion air duct.
The projections of the two arc wind shields 12c on the plane parallel to the rotation axis of the centrifugal fan 14 should be semicircular, and the arc length of the arc wind shields 12c is approximately the same as the semicircular arc length of the corresponding air outlet. The projection of the arc-shaped partition wall 154 on the plane parallel to the rotation axis of the centrifugal fan 14 is a semicircle, the arc length of the arc-shaped partition wall 154 is substantially the same as the arc length of the semicircle corresponding to the air outlet, and the projection of the curved section 152a of the air guide duct opposite to the arc-shaped partition wall 154 on the plane parallel to the rotation axis of the centrifugal fan 14 is a semicircle, and the arc length of the curved section 152a may be substantially the same as the arc length of the arc-shaped partition wall 154. Therefore, when the front panel 12 rotates to the initial position or the final position, the arc wind shield 12c and the guide wind channel form a circular wind channel matched with the corresponding wind outlet, and the wind outlet smoothness is improved.
To more clearly understand the cooperation of the front panel 12 with the air guide duct of the air guide sleeve during rotation, the following description is given as an example. As shown in fig. 2 and 5, taking a state where the front panel 12 is assembled on the front side of the rear housing 11 as an example, the arc-shaped wind deflector 12c at the upper wind outlet 12a of the front panel 12 is located on the lateral left side of the upper wind outlet 12a, the arc-shaped wind deflector 12c at the lower wind outlet 12b is located on the lateral right side of the lower wind outlet 12b, when the front panel 12 is in the initial position, the upper wind outlet 12a is located right above the front panel 12, and the lower wind outlet 12b is located right below the front panel 12, at this time, the arc-shaped wind deflector 12c at the upper wind outlet 12a and the partition wall 154 of the upper pod 15 form a circular wind tunnel, and the arc-shaped wind deflector 12c at the lower wind outlet 12b and the partition wall 154 of the. When the front panel 12 rotates counterclockwise from the initial position to the end position, the arc wind deflector 12c at the upper air outlet 12a and the curved section 152a of the wind guide channel of the upper wind deflector 15 form a circular wind channel, and the arc wind deflector 12c at the lower air outlet 12b and the curved section 152a of the wind guide channel of the lower wind deflector 15 form a circular wind channel.
Therefore, the size and the shape of the arc wind deflector 12c, the size and the shape of the curved section 152a of the guide air duct and the size and the shape of the arc partition wall 154 are limited to meet the corresponding relations, so that when the front panel 12 rotates to the initial position or rotates to the final position, the arc wind deflector 12c and the guide air duct can form a circular air duct matched with the corresponding air outlet, and the air outlet smoothness is improved.
As mentioned above, when the front panel 12 rotates to the initial position, the upper outlet 12a should be located right above the front panel 12, and the lower outlet 12b should be located right below the front panel 12, that is, when the front panel 12 is located at the initial position, the circle center of the upper outlet 12a and the circle center of the lower outlet 12b are both located on the vertical center line of the housing. The upper outlet 12a and the lower outlet 12b may be symmetrically distributed with respect to the transverse center line of the casing, further enhancing the aesthetic appearance of the indoor unit 10.
In some embodiments, the rotation angle of the front panel 12 from one position to the other of the initial position and the final position ranges from 40 ° to 50 °. For example, the rotation angle of the front panel 12 between the initial position and the final position is 45 °. As shown in fig. 2, the front panel 12 is rotated counterclockwise by a certain angle from the initial position to the final position. In other embodiments, the front panel 12 can be rotated clockwise from the initial position to the final position by adjusting the positions of the two centrifugal fans 14 and the two air guides 15.

Specifically, as shown in fig. 5, the front panel 12 includes a plate body 121 and a circular peripheral wall 122 (not identified) extending rearward from the plate body 121 in a circumferential direction, and the rack 101 may be formed inside the circular peripheral wall 122 of the front panel 12. As shown in fig. 5, the number of the driving units is two, two racks 101 of the two driving units are formed inside the circular peripheral wall 122 of the front panel 12, and the two racks 101 are distributed oppositely. For example, as shown in fig. 5, one rack 101 is formed at the upper end inside the circular peripheral wall 122 of the front panel 12, the other rack 101 is formed at the lower end inside the circular peripheral wall 122 of the front panel 12, and the two racks 101 are symmetrically distributed with respect to the lateral center line of the circular peripheral wall 122 of the front panel 12. The aforementioned sealing ring may be disposed in the circumferential direction of the front end surface of the circular peripheral wall 122 to ensure that the front panel 12 is in close contact with the front end surface of the rear shell 11.
It will be appreciated that, for the case where the two racks 101 are distributed up and down, the position of the upper air outlet 12a, the position of the curved air deflector 12c at the upper air outlet 12a, and the positions of the lower air outlet 12b and the curved air deflector 12c at the lower air outlet 12b should not interfere with the rotation of the front panel 12, taking into account the positions of the racks 101 and the gears.
In an alternative embodiment, two racks 101 may be formed on two inner sides of the circular peripheral wall 122 opposite to each other in the transverse direction, that is, one rack 101 is formed on the inner side of the center of the left end of the circular peripheral wall 122, and the other rack 101 is formed on the inner side of the center of the right end of the circular peripheral wall 122.
Referring to fig. 2 and 3, an avoiding gap 15c for avoiding the corresponding heat exchanger 13 is formed on the rear side wall of each air guide sleeve 15, and the avoiding gap 15c provides an avoiding space for the corresponding heat exchanger 13, so that the arrangement position and the size of the heat exchanger 13 are ensured. As shown in fig. 2 and with reference to fig. 3, the escape notch 15c of the upper air guide sleeve 15 provides an escape space for the upper end of the heat exchanger 13 on the lateral left side, and the escape notch 15c of the lower air guide sleeve 15 provides an escape space for the lower end of the heat exchanger 13 on the lateral right side.
