Description

本発明は、筺体内で、管内を流れる湯水と筺体内に取り込んだ燃焼ガスとを熱交換する熱交換器及びその熱交換器を備える給湯装置に関する。 The present invention relates to a heat exchanger for exchanging heat between hot water flowing in a pipe and combustion gas taken into the casing, and a hot water supply apparatus including the heat exchanger.

筺体内に設けられた複数の管内を流れる湯水を、筺体内に取り込んだ燃焼ガスで加熱する熱交換器は、管が所定の間隔を空けて配置される。これは、管内の湯水と燃焼ガスとの熱交換の効率化を図るためである。また、管の間隔が狭くなった箇所には結露水がたまることから、管を所定の間隔を空けて配置することは、管の間に結露水がたまるのを防止する点でも有効である。
特許文献１には、曲げ加工が施された線材又は棒状部材を用いて、管を所定の間隔を空けて配置する例が記載されている。 In a heat exchanger that heats hot water flowing through a plurality of pipes provided in a casing with combustion gas taken into the casing, the pipes are arranged at predetermined intervals. This is to improve the efficiency of heat exchange between the hot water in the pipe and the combustion gas. In addition, since condensed water accumulates at a place where the interval between the tubes becomes narrow, it is effective to prevent the condensed water from being accumulated between the tubes by arranging the tubes at a predetermined interval.
Patent Document 1 describes an example in which pipes are arranged at predetermined intervals using a wire rod or a rod-shaped member that has been subjected to bending.

A hot water supply pipe 39 for supplying hot water to a stand or the like is connected.
When combustion gas is generated in the casing 19 due to combustion of the combustible fuel by the burner unit 20, the combustion gas heats the hot water in the pipes 30 and 38 while passing through the cylinder 21, and the casing 16 passes through the gas intake port 23. The hot water in the tube 17 and the water in the tube 35 are heated while moving in the housing 16 and discharged from the gas exhaust port 22 to the outside of the housing 16.

筺体１９内に燃焼ガスが発生している際に、浴槽内の湯を風呂戻り管２４、ヘッダ２５、複数の管１７、ヘッダ２８、連結管３１、管３０及び風呂往管３２を順に通過させて浴槽に戻すことによって、浴槽内の湯の温度を上昇させることができる。そして、筺体１９内に燃焼ガスが発生している際に、水道水を水道管３４及びヘッダ３３を介して複数の管３５に供給することによって、水道水は、管３５を通過中に加熱され、ヘッダ３６、連結管３７を経由して管３８に流入し、管３８を通過中に再度加熱された後、給湯管３９に送られる。 When combustion gas is generated in the housing 19, the hot water in the bathtub is passed through the bath return pipe 24, the header 25, the plurality of pipes 17, the header 28, the connecting pipe 31, the pipe 30 and the bath forward pipe 32 in order. By returning to the bathtub, the temperature of the hot water in the bathtub can be raised. When the combustion gas is generated in the housing 19, the tap water is heated while passing through the pipe 35 by supplying the tap water to the plurality of pipes 35 via the water pipe 34 and the header 33. Then, it flows into the pipe 38 via the header 36 and the connecting pipe 37, is heated again while passing through the pipe 38, and then sent to the hot water supply pipe 39.

また、潜熱熱交換器１０は、図３に示すように、筺体１６の底部に上げ底４１が設けられ、ガス取込口２３は上げ底４１に形成されている。そして、上げ底４１には、複数の管３５の下方にドレイン水を前方に流す案内部材４２が設けられ、筺体１６の底部前方には、ドレイン水を筺体１６外に排出する排水部４３が形成されている。 As shown in FIG. 3, the latent heat exchanger 10 is provided with a raised bottom 41 at the bottom of the housing 16, and the gas inlet 23 is formed at the raised bottom 41. The raised bottom 41 is provided with a guide member 42 that allows drain water to flow forward below the plurality of tubes 35, and a drainage portion 43 that discharges drain water to the outside of the housing 16 is formed in front of the bottom of the housing 16. ing.

以上、本発明の実施の形態を説明したが、本発明は、上記した形態に限定されるものでなく、要旨を逸脱しない条件の変更等は全て本発明の適用範囲である。
例えば、管が第２の側壁部に形成されたエンボスによって位置決めされる熱交換器は、潜熱熱交換器として採用される必要はなく、顕熱熱交換器や単独の熱交換器等として採用することができる。
