Document Type and Number:
Japanese Patent JP2021162170
Kind Code:
A
Abstract:
To provide a pipe structure which enables a metallic drain pipe having a small inner diameter to be easily connected to a resin drain pipe.SOLUTION: A pipe structure 1 drains drain water generated from an air conditioner, and includes: a metallic drain pipe 10 connected to the air conditioner; a connection unit 20 connected to the metallic drain pipe; a resin heat insulation joint 55 connected to the connection unit; resin drain pipes 80A, 80B having foam layers 82A, 82B and connected to the resin heat insulation joint; and a diameter expanding part 45 which is disposed between the metallic drain pipe and the resin heat insulation joint and converts an inner diameter so that an inner diameter of a downstream side portion becomes larger than an inner diameter of an upstream side portion. The resin heat insulation joint has: a first connection part 57 connected to the connection unit; second connection parts 58, 59 connected to the resin drain pipes; and a body part 56 including a first heat insulation layer S3. The connection unit has: a third connection part 24 connected to the metallic drain pipe; and a fourth connection part 40 connected to the first connection part of the resin heat insulation joint.SELECTED DRAWING: Figure 2
