Title: Exhaust device of water heater
Inventor: HASHINO ICHIROU
IPC: F23J13/00
Filed: 1979-06-22
Abstract: PURPOSE: To decrease an exhaust gas temperature and dilute exhaust gases and especially obtain a silencing effect on low frequency noise by blowing out the outside air with an exhaust fan orthogonally to the flow of exhaust gases.  
     CONSTITUTION: Exhaust gases generated by the combustion of a burner 5 passes a flue 8, an exhaust cylinder 20, an exhaust chamber 47, an exhaust passage 35 and an exhaust chamber 48 and is discharged from an exhaust cylinder 31 to the outside. Blowing out air from an exhaust fan 42 is blown out into the exhaust cylinder 31 from its bottom. By so doing, noise entering the exhaust chamber 48 from the exhaust passage 35 collides violently with the blowing out air intersecting at right angles with the direction blown out by the fan 42. Therefore, sound waves collide violently against a wall softer than a sound absorbing material thereby obtaining a great effect on the silencing of low frequency noise and further cooling by the blowing out air, resulting in very effective silencing.
