PROBLEM TO BE SOLVED: To prevent abrasion of a fin of a heat exchanger even when it is used for a long time in a region with high water feed pressure, in a bathroom heater with a sauna function which has a steam generating means 10 provided within a heater body 2 and including a fin-tube heat exchanger 11 for supplying a heating medium heated by a heat source machine and a spray nozzle 13 for applying water to the heat exchanger 11 and supplies steam generated by the steam generating means 10 to inside of a bathroom.SOLUTION: The heat exchanger 11 is arranged in an erected posture, and a collision plate 12 is provided above the heat exchanger 11. Water is sprayed from the spray nozzle 13 toward the collision plate 12, and is fell down from the upper side to the heat exchanger 11 via the collision plate 12. The lateral part 12a on the opposite side to the part where the spray nozzle 13 is arranged of the collision plate 12 is brought into contact with an upper edge of the fin 11a of the heat exchanger 11, and the collision plate 12 is erected from the upper edge of the fin 11a in the width direction position of the fin 11a through which a tube 11b of the heat exchanger 11 is penetrated.COPYRIGHT: (C)2010,JPO&INPIT【課題】暖房機本体2内に蒸気発生手段10を備え、蒸気発生手段で発生させた水蒸気を浴室内に供給するサウナ機能付き浴室暖房機であって、蒸気発生手段は、熱源機で加熱された熱媒体を供給するフィンチューブ型の熱交換器11と、熱交換器に水をかける噴霧ノズル13とで構成されるものにおいて、給水圧の高い地域で長期間使用しても熱交換器のフィンが削れることのないようにする。【解決手段】熱交換器11は起立姿勢で配置され、熱交換器11の上方に衝突板12が設けられる。そして、噴霧ノズル13から衝突板12に向けて水が噴霧され、この水が衝突板12を介して熱交換器11に上方から降りかかるようにする。また、衝突板12の噴霧ノズル13の配置部とは反対側の側部12aは、熱交換器11のフィン11aの上端に接し、熱交換器11のチューブ11bが貫通するフィン11aの幅方向位置でフィン11aの上端から衝突板12が立ち上がる。【選択図】図1
