[0002] As a means of public transportation, the subway carries a very large number of passengers every day, so the hygiene and safety of the subway is very important.

[0003] The air-conditioning unit of the intercity EMU is located on the roof. In order to ensure the air quality inside the car and the stable operation of the air-conditioning, the mixing air chamber needs to be disassembled regularly to flush the evaporator fins and condensate drain tank inside. However, there are many electrical connectors and air ducts inside that cannot be directly flushed, so plastic film and tape are needed for protection before the flushing operation, and then the evaporator and water tank are cleaned.

[0004] Because each EMU has 16 air conditioning units, each unit needs to be properly waterproofed before operation, which consumes a significant amount of time. After the operation is complete, when removing the waterproofing, it also takes considerable time to wipe away any accumulated water on the plastic film to prevent it from sliding off and causing water intrusion into the equipment. The film also needs to be scrapped after use. In summary, each cleaning operation for the air conditioning evaporator fins and condensate drain tanks consumes significant manpower, material resources, and time, and the large amount of discarded plastic film is not environmentally friendly.

[0005] Therefore, in view of the deficiencies in the prior art, a water-isolating device for flushing a top-mounted air-conditioning evaporator of an intercity train is provided. Utility Model Content
