The additional air transversely flowing in the main body part 401 of the additional air duct 40 can be uniformly guided to each air outlet 41 by arranging the guide ribs 46 on the downstream side of each air outlet 41 in a one-to-one correspondence manner; meanwhile, the flow guiding rib 46 is provided to include the arc section 462 and the straight section 461, so that the structure of the flow guiding rib 46 is simple, and meanwhile, when the airflow flows to the position of the flow guiding rib 46, the arc section 462 can reduce the flow resistance of the airflow, so that the airflow in the main body portion 401 can smoothly receive the flow guiding from the back to the front by the flow guiding rib 46. In the embodiment shown in fig. 6, since the left and right lengths of the air outlets 41 are the same, and the vertical heights of the air outlets are sequentially increased, the plurality of air guide ribs 46 are uniformly arranged at intervals; in the embodiment shown in fig. 8, since the plurality of air outlets 41 have the same vertical height and the horizontal length sequentially increases, the horizontal distance between the plurality of air guide ribs 46 increases sequentially along the airflow transverse flow direction.

With continued reference to fig. 6 and 8, in some embodiments, the main body 401 is further provided with an end deflector 47 on the upstream side of the most upstream outlet 41 in the airflow transverse flow direction. That is, after the air flows into the main body 401, the air firstly passes through the diversion function of the end diversion rib 47 and then passes through the diversion function of the plurality of diversion ribs 46. The end deflector rib 47 has a shape convexly curved toward the windward side thereof, i.e., an arc shape convexly curved from the rear to the front toward the side end 402 where the air inlet 42 is opened. Therefore, part of the air flow flowing to the end diversion rib 47 can be guided backwards, so that the air flow and other air flows jointly flow along the transverse direction, and the phenomenon that the air flow flowing into the main body 401 is uneven due to the fact that the air flow is sent out through the air outlet 41 adjacent to the air inlet 42 by the air outlets 41 is avoided. In addition, the protruding direction of the end diversion rib 47 can reduce the flow resistance of the end diversion rib 47 to the air flow, and avoid the undesirable phenomena of vortex and the like caused by the formation of a concave cavity on the windward side of the end diversion rib 47. Further, in order to ensure the uniformity of the air outlet in the transverse direction of the air outlets 41, the shapes and sizes of the diversion ribs 46 are the same, and the length of the end diversion rib 47 in the front-rear direction is set to be smaller than the length of the diversion rib 46 in the front-rear direction. If the length of the end diversion rib 47 in the front-rear direction is too large, the airflow quantity at the diversion rib 46 adjacent to the end diversion rib 47 may be small, and the diversion ribs 46 cannot retain a sufficient amount of airflow on the windward side thereof, so that the uniformity of the air outlet of the plurality of air outlets 41 in the transverse direction cannot be ensured.
