    摘要： A latent heat recovery heat exchanger includes a case, a heat exchange portion, and a straightening vane. The heat exchange portion includes a plurality of heat transfer plates surrounded by a peripheral wall portion of the case and layered on one another, each of the plurality of heat transfer plates extending in a direction from an inlet toward an outlet. The straightening vane includes a top plate portion covering the plurality of heat transfer plates so as to close a space between the plurality of heat transfer plates in end portions of the plurality of heat transfer plates in a direction intersecting with a direction of layering of the plurality of heat transfer plates when the heat exchange portion is viewed from the inlet toward the outlet.

    摘要： In a primary heat exchanger, a heat conduction pipe is arranged as one connected pipe in a lower stage and an upper stage in a manner extending back and forth through a plurality of fins. The heat conduction pipe is arranged such that a pitch between the heat conduction pipes in the upper stage is shorter than a pitch between the heat conduction pipes in the lower stage. In addition, the heat conduction pipe is arranged such that a position in a center of each heat conduction pipe in the upper stage in a second direction orthogonal to a first direction in which the heat conduction pipe extends and a position in a center of each heat conduction pipe in the lower stage in the second direction are displaced from each other.

    摘要： A hot water apparatus includes a heat exchanger and a housing. A case of the heat exchanger has a circumferential wall portion, a lower opening, and a flange portion. A case of the housing has a flange portion, a circumferential wall portion, and an upper opening. The circumferential wall portion includes a downwardly-extending wall portion inserted into the inside of the circumferential wall portion through the upper opening. In a state where the downwardly-extending wall portion is arranged inside the circumferential wall portion, the lower opening is located below an upper surface of the flange portion, and a flange connection is formed between the heat exchanger and the housing.

    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.
