The first drainage portion 110 is in butt joint with one side wall of the volute 200, and can guide wind flowing out of the volute 200 from flowing along the extending direction of the side wall to flowing along the extending direction of the first drainage portion 110, so that the lower end of the evaporator 400 through which no air flow passes originally can have air flow passing therethrough, the problem of uneven air flow speed distribution at the position can be improved, and the heat exchange effect of the lower end of the evaporator 400 is further improved. In addition, the second flow guiding portion 320 is in butt joint with the other side wall of the volute 200, so that the wind flowing out of the volute 200 can be guided from flowing along the extending direction of the other side wall to flowing along the extending direction of the second flow guiding portion 320, and the distance between the second flow guiding portion 320 and the first flow guiding portion 110 in the first direction is gradually reduced and then gradually increased, in this way, the second flow guiding portion 320 can guide the wind flowing out of the volute 200 to flow towards the direction close to the evaporator 400 and then away from the evaporator 400, and the guiding of the second flow guiding portion 320 can raise the flow speed of the airflow, so that more airflow flows through the area, away from the air outlet of the volute 200, of the interior of the evaporator housing 300, and further the problem of uneven flow speed of the airflow in different areas of the interior of the evaporator housing 300 is solved, and accordingly, the noise problem in the interior of the air passage is improved, and the heat exchange effect of the upper end of the evaporator 400 is improved.

Further, the second drainage portion 320 is connected to the water receiving member 100, and the second drainage portion 320 is disposed at a position where one of the side walls of the scroll case 200 is located, so that wind flowing out from the scroll case 200 can directly flow along the extending direction of the second drainage portion 320.

Wherein the second drainage portion 320 may include a first drainage wall 321, a second drainage wall 323, and a first arc-shaped transition wall 322, the first drainage wall 321 may be configured to extend obliquely toward the first drainage portion 110, the first arc-shaped transition wall 322 may be located between the first drainage wall 321 and the second drainage wall 323 and smoothly transition with the first drainage wall 321 and the second drainage wall 323, respectively, and the second drainage wall 323 may extend obliquely away from the first arc-shaped transition wall 322 from the first drainage portion 110. In this way, the first drainage wall 321 may be connected to the air outlet of the volute 200, and guide the wind flowing out of the volute 200 to the first arc transition wall 322 and the second drainage wall 323, and since the first drainage wall 321 and the second drainage wall 323 are in a V-shaped structure, the direction of the wind can be changed, so that the wind that does not pass over the second drainage wall 323 flows toward the low speed region above the second drainage wall 323 (as shown in fig. 8), so as to improve the airflow speed and improve the noise problem inside the air passage.

That is, the second guide wall 323 may be inclined to extend at any suitable angle within the range of-105 ° < α <180 ° according to actual requirements, so as to guide the wind flowing out of the scroll case 200 through the second guide wall 323 toward a region farther from the air outlet of the scroll case 200 (i.e., guide the wind to be closer to the uppermost end of the evaporator 400 in the use state), thereby improving the problem of uneven flow velocity of the air stream at different regions inside the evaporator housing 300, and thus improving the heat exchange effect of the evaporator 400 while improving the noise problem inside the air duct.
