口10が設けられている。11は給気ファン1の吸入口
、12は前記バーナ7に対向して設けられたガス供給部
である。In FIG. 1, reference numeral 1 denotes an air supply fan, which is provided so as to protrude outside of the casing 2, and a sound absorption passage 4 provided inside the casing 2 is located downstream of the air outlet 3 of the air supply fan 1. A sound absorbing material 5 is provided on the inner surface of the sound absorbing passage 4 which communicates with the sound absorbing passage 4 . Furthermore, inside the casing 2, a current plate 6, a burner 7, a combustion chamber 8,
A heat exchanger 9 is provided, and an exhaust port 10 is provided in communication with the heat exchanger 9. 11 is an inlet of the air supply fan 1, and 12 is a gas supply section provided opposite to the burner 7.
上記構成により、給湯器の燃焼用空気は給気ファン1の
吸入口11、給気ファン1、給気ファン1の吹出口3、
吸音通路4を通過した後、一部は燃焼用二次空気として
整流板6、他部は燃焼用−次空気としてガスとともにバ
ーナ7に入り、バーナ7の炎ロアaで燃焼に使用された
後、熱交換器9、排気口10を通過してケーシング2よ
り排気される。With the above configuration, the combustion air of the water heater is supplied to the intake port 11 of the air supply fan 1, the air supply fan 1, the outlet 3 of the air supply fan 1,
After passing through the sound absorption passage 4, part of the air enters the baffle plate 6 as secondary air for combustion, and the other part enters the burner 7 as secondary air for combustion together with the gas, and is used for combustion in the flame lower a of the burner 7. , a heat exchanger 9, and an exhaust port 10 to be exhausted from the casing 2.
ここで粘気ファン1の発生する騒音について説明すると
、給気ファン1の持つ固有の騒音スペクトルは500H
2以上の高周波数の騒音レベルが主に高く、高周波数の
騒音はグラスウールなどの吸音材による吸音が効果的で
ある。To explain the noise generated by the viscous fan 1, the unique noise spectrum of the air supply fan 1 is 500H.
The noise level of high frequencies of 2 or more is mainly high, and high frequency noise is effectively absorbed by sound absorbing materials such as glass wool.
給気ファン1が発生する騒音は上記構成により給気ファ
ン1の吸入口11から給湯器のケーシング2の外部へ出

ものがある。このような騒音に対して上記実施例では給
気ファン1の発生する高周波数の騒音を給気ファン1の
吹出口3の下流側に設けた吸音通路4によって吸収し、
その結果給湯器のケーシング2の外部へ出る騒音を低減
し、給湯器の低騒音化を向上させることができる。Due to the above configuration, the noise generated by the air supply fan 1 is emitted from the intake port 11 of the air supply fan 1 to the outside of the water heater casing 2, and is exhausted from the air outlet 3 of the air supply fan 1 via the combustion chamber 8. There is something that comes out of the casing 2 of the water heater from the opening 10. In response to such noise, in the embodiment described above, the high frequency noise generated by the air supply fan 1 is absorbed by the sound absorption passage 4 provided downstream of the air outlet 3 of the air supply fan 1.
As a result, the noise emitted to the outside of the casing 2 of the water heater can be reduced, and the noise reduction of the water heater can be improved.
