Drain pan

Abstract

A drain pan is disposed below a cooling unit that cools air, receives water of condensation that falls from the cooling unit, and guides the water of condensation into an outer portion of the vehicle air-conditioning apparatus. The drain pan includes a water receiving region, and receives water of condensation; a drain port disposed at a bottom-center portion of the water receiving region; and a rib disposed upright in the bottom portion on a dividing line that passes through the drain port and divides the water receiving region.

1 . A drain pan disposed below a cooling unit that cools air, receiving water of condensation that falls from the cooling unit, guiding the water of condensation into an outer portion of the vehicle air-conditioning apparatus, the drain pan comprising:
 a water receiving region receiving the water of condensation;   a drain port disposed at a bottom-center portion of the water receiving region; and   a rib disposed upright in the bottom portion on a dividing line that passes through the drain port and divides the water receiving region.   
     
     
         2 . The drain pan according to  claim 1 , wherein the rib is disposed at least downstream side of the drain port with respect to airflow direction. 
     
     
         3 . The drain pan according to  claim 1 , wherein the rib inclines with respect to the direction of flow of the water of condensation. 
     
     
         4 . The drain pan according to  claim 1 , further comprising:
 a canal for drain connected to incline with respect to the drain port, and having an inner wall face, wherein   the rib is disposed to be relatively removed from the region in which the inner wall face is connected at an acute angle with respect to the bottom portion, and to be relatively close to the region in which the inner wall face is connected at an obtuse angle with respect to the bottom portion.
