Cabin air conditioner condensate water discharge treatment device

The invention relates to a cabin air conditioner condensate water discharge treatment device. The cabin air conditioner condensate water discharge treatment device is characterized in that a water discharging opening is formed in the bottom between the cabin outer wall of an N layer cabin and a cabin inner sub-plate, and the water discharging opening communicates with a condensate water discharge pipe leading to an (N-1) layer cabin; an indoor unit condensate water discharge pipe of an air conditioner indoor unit in each cabin penetrates through a deck of the layer and is converged toa condensate water discharge header pipe located between the deck of the N layer and the ceiling of the cabin of the (N-1)layer, and the condensate water discharge header pipe communicates with the side direction of the condensate water discharge pipe of the cabin of the (N-1) layer in a converging mode; the condensate water discharge pipe of the (N-1) layer cabin penetrates through the deck of the layer and communicates with the
