れた後に貯湯槽給水栓１５に入るように構成しである。An embodiment of the present invention will be described below with reference to the drawings. FIG. 3 shows an engine-driven water heater according to an embodiment of the present invention. Reference numeral 8 denotes an engine body serving as a heat source, and the engine drives a compressor (not shown) to perform air conditioning and heating, and uses condensation heat to heat hot water 11 by a heat exchanger 10 in a hot water storage tank 9. do. The engine exhaust heat is recovered by the cylinder head cooling heat exchanger 12 and the exhaust gas heat exchanger 13, and the exhaust heat recovery heat exchanger 1 in the hot water storage tank
4 to be heated for hot water supply. A water tap 15 is provided at the bottom of the hot water storage tank 9, and a hot water tap 16 is provided at the top. The water that enters the water tap 16 is passed through the water stop valve 17 to the muffler 1 connected to the exhaust gas heat exchanger 13 of the engine body 8.
8 and exchanges heat with the exhaust gas at the muffler 18, and then enters the hot water tank faucet 15.

目的で、第４図乙のように全体をジャケット１９で囲む
構造や、ｂのように給水パイプ２ｏをマフラー壁面に巻
き付ける構造などが考えられる。In this case, the structure of the heat exchanger in the sound-absorbing muffler 18 may be a structure in which the entire structure is surrounded by a jacket 19 as shown in Fig. 4 B, in order to increase the thickness of the muffler wall surface, as shown in Fig. 4. , a structure in which the water supply pipe 2o is wrapped around the muffler wall surface as shown in b is conceivable.

消音マフラー１８内で排ガスの潜熱をも回収できる。In such a configuration, water is supplied to the hot water tank 9 from the water stop valve 17 through the muffler 18 to exchange heat with the exhaust gas 21 before entering the hot water tank. At this time, look at the temperature of the exhaust gas in Figure 2. The solid line is for the conventional case, and the broken line is for the present invention. As is clear from the figure, in the conventional example, the exhaust gas having the exhaust gas heat exchanger outlet temperature 'rao is naturally radiated to a certain extent by the muffler and then released in the TMO. -In the invention of strength wood'
It further exchanges heat with the supply water from reo, and is discharged at TM (+"!).At this time, the temperature of the supply water is at room temperature regardless of the system temperature, and TMO' becomes below the dew point temperature, and the exhaust gas is discharged in the muffler 18. The latent heat of can also be recovered.
マフラーに入る排ガスは、温度が比較的低いために潜熱
の割合が大きく、潜熱を回収できることは排熱回収効率
が大幅に向上するものである。Since the exhaust gas entering the muffler has a relatively low temperature, it has a large proportion of latent heat, and the ability to recover latent heat greatly improves the exhaust heat recovery efficiency.
