摘要： A fan includes: an impeller including a main plate having a first plane, a plurality of first blades each formed the first plane, and a shroud formed integrally with the plurality of first blades; a fan case; a drive source; and a rotation shaft. The first blades each include a linearly protruding region that is linearly increased in height from an outer circumferential side to an inner circumferential side, and a curvedly protruding region that is curvedly increased in height from the outer circumferential side to the inner circumferential side, the height extending in a direction in which each first blade protrudes. The linearly protruding region is welded to the main plate. Accordingly, a highly durable fan can be implemented that allows sufficient durability to be maintained even under a high temperature environment or an acid environment.

摘要： A fan serves to suction combustion gas which has passed through a secondary heat exchanger and emitting combustion gas to the outside of a water heater. A drainage water discharge pipe is connected to the secondary heat exchanger in order to discharge the drainage water produced as a result of recovery of latent heat in the secondary heat exchanger to the outside of the secondary heat exchanger. An air passage pipe is connected to an exhaust box. A Y-shaped pipe joint has a flow path allowing merging of the drainage water discharge pipe and the air passage pipe, and the flow path after merging leads to the outside of the water heater.
