When the water pressure H1> H2, the water receiving tray 31 is not yet full, and the B water level can pass the high point C, no water leakage is caused (the case where the V-shaped water bend is small). When the water receiving tray 31 is full and the water level B has not yet passed the high point C, water leakage is caused. When the return water bending height difference H3 is less than 47mm, the occurrence of water leakage caused by the air-holding in the drain pipe 1 can be avoided, and hidden danger of air-holding and water leakage in the drain pipe 1 exists under other conditions.

Therefore, the water drain pipe assembly of the embodiment of the utility model can exchange the air in the water drain pipe 1 with the outside air by arranging the waterproof and breathable piece 2 at the position of the water drain pipe 1 adjacent to the water inlet 11, so that the air in the air column 4 can be smoothly discharged, avoid the interior machine 3 of air conditioner to leak to because waterproof characteristic of waterproof ventilative spare 2, the rivers in the drain pipe 1 can not leak from the position of waterproof ventilative spare 2, improved the reliability that the drain pipe subassembly was used.
