Pipe connecting structure of water heater

A pipe connecting structure of a water heater including:

• a tap water inlet pipe connected to a heat exchanger at a tap water inlet,
• a hot water supply pipe connected to a hot water outlet at the heat exchanger,
• a flow rate sensor measuring flow rate of tap water introduced into the tap water inlet,
• a flow rate control valve controlling flow rate of hot water discharged at the hot water outlet,
• an integral pipe body connecting the tap water inlet, the tap water inlet pipe, the hot water supply pipe, and the hot water outlet, and
• a flow rate sensor insertion part, in which the flow rate sensor is located, the flow rate sensor insertion part being located at one side of the tap water inlet and exposed outside of the water heater housing.

• an integral pipe body connecting the tap water inlet, the tap water inlet pipe, the hot water supply pipe, and the hot water outlet,
• a bypass flow path connected between the tap water inlet pipe and the hot water supply pipe,
• a mixing valve controlling the flow rate of the tap water conveyed through the bypass flow path, wherein
• the bypass flow path is integral with the pipe body, and
• the pipe body comprises
• a tap water inlet part coupled to a connecting pipe through which tap water is introduced,
• a flow rate sensor insertion part in communication with the tap water inlet part, downwardly inclined from one side of the tap water inlet part and extending to and exposed outside of a water heater housing, and in which the flow rate sensor is located, and
• a mixing valve insertion part extending to one side of an upper end of the flow rate sensor insertion part, with the mixing valve located in the mixing valve insertion part, and coupled to a connecting pipe of a tap water inlet pipe through which tap water is introduced into the heat exchanger, wherein the tap water introduced into the tap water inlet part is introduced into the flow rate sensor insertion part in a downwardly inclined direction, and conveyed toward the mixing valve insertion part.
