    • So as to provide a latent heat recovery-type water heater capable of certainly preventing drain generated by heat exchange from being discharged out of an exhaust portion through an outlet with entrained by a flow of combustion gas, an exhaust portion 9 is formed by an exhaust portion constituting-body 25 attached above a secondary heat exchanger 7. The exhaust portion 9 includes therewithin a deflector 26 and a distribution board 27 opposed to the deflector 26. The deflector 26 has a deflection board 30 extending substantially vertically downward from a top face 9a of the exhaust portion 9, so as to form a gap 35 between a lower end of the board 30 and a bottom face 9b of the exhaust portion 9. A flowing direction of combustion gas introduced into the exhaust portion 9 through an opening 21 of the bottom face 9b is deflected by passing through the gap 35, and the combustion gas flows toward the distribution board 27. The combustion gas hits on the distribution board 27 to be distributed within the exhaust portion 9, thereafter being discharged through an exhaust opening 23.
    • 为了提供一种潜热回收式热水器,其能够可靠地防止由热交换产生的排水通过由燃烧气体流引起的排出口排出出口,排气部分9由排气 部分构成体25安装在二次热交换器7上。排气部分9中包括偏转器26和与偏转器26相对的分配板27.偏转板26具有偏转板30,偏转板30从顶面9a基本垂直向下延伸 从而在板30的下端和排气部9的底面9b之间形成间隙35.通过该排气部9的开口21引入到排气部9的燃烧气体的流动方向 底面9b通过间隙35而偏转,并且燃烧气体朝向配电板27流动。燃烧气体撞击配电板27以进行分配 在排气部分9内,然后通过排气开口23排出。
