| Zusammenfassung: | To provide a forced air supply/exhaust type hot water supply device capable of suppressing generation of noise from an air supply duct.SOLUTION: A force air supply/exhaust type hot water supply device includes: a blower fan; a burner for burning a fuel by receiving supply of combustion air from the blower fan; a burner case for housing the burner; a heat exchanger portion for heating hot water/water by heat exchange with a combustion gas generated by combustion of the burner; an exhaust cylinder for exhausting the combustion gas after the heat exchange; an air supply cylinder for introducing the combustion air from the external; and an air supply duct for supplying the combustion air from the air supply cylinder to the blower fan, in which a downstream end portion of the air supply duct and the blower fan are connected in a state of holding a packing therebetween. A vibration-proof material for reducing vibration of the air supply duct is disposed between the burner case and the air supply duct in a manner of pressing the air supply duct.SELECTED DRAWING: Figure 2
【課題】給気ダクトからの騒音発生を抑制することができる強制給排気式給湯装置を提供すること。【解決手段】送風ファンと、送風ファンから燃焼用空気の供給を受けて燃料を燃焼させるバーナと、バーナを収容するバーナケースと、バーナの燃焼により発生する燃焼ガスとの熱交換により湯水を加熱する熱交換器部と、熱交換後の燃焼ガスを排気するための排気筒と、燃焼用空気を外部から導入するための給気筒と、給気筒から送風ファンに燃焼用空気を供給する給気ダクトを備え、給気ダクトの下流端部と前記送風ファンとがパッキンを挟み込んだ状態で接続されている強制給排気式給湯装置において、給気ダクトの振動を軽減する防振材が、バーナケースと給気ダクトの間に給気ダクトを押圧するように配設されている。【選択図】図２ |
