温水器の排水装置。 A relief valve is attached to the top of the hot water tank inside the housing that has the water supply and hot water supply pipes, and is equipped with a relief valve that automatically opens and closes depending on the tank internal pressure and a manual opening/closing lever for checking operation. A suction air hole is provided in the middle of the connection and opens to the atmosphere, and a relief pipe is provided with the other end leading downward, and a drain pipe is led out from the bottom of the tank via a drain plug. In the case where the outlet end of the drain pipe is connected to the other end of the relief pipe and connected as a common drainage channel led out of the casing, one end is located in the upstream area of the area above the vicinity of the air hole of the relief pipe. The upper base of the side is connected and opened, and the other end that continues below the opening is reduced in diameter to a desired length, and an inner relief pipe is installed therein to extend into the relief pipe in the downstream area, and the downstream area of this part is It has a double pipe structure, and a communication path connected to the air hole is formed in the downstream region divided into the upstream region between the relief pipe and the inner relief tube, and the inner relief tube is compressed. Diameter passage cross-sectional area S1 and passage cross-sectional area S2 of the communication passage
, and the relationship between the passage cross-sectional area S3 of the air hole is S3
A water heater drainage device characterized by setting <S1<S2.
