Sound arresting structure of gas hot water supply vessel

摘要

(57) Abstract Objective The amount of storm sewage which penetrates to inside the heat exchanger substantially decrease yesOffer of sound arresting structure of the gas hot water supply vessel which is made talent is designated as purpose. Constitution Directing to the top of heat exchanger, 22 the burnup which is dischargedGathering the exhaust gas, the exhaust air cutting cylinder 23 which it leads to front exhaust air opening 29As it provides, inside this exhaust air cutting cylinder 23 the fluewaySound arresting structure of the gas hot water supply vessel where the sound arresting body 27 which squeezes 28 is providedIn structure, acoustic material 25 is contained inside exhaust air cutting cylinder 23Be able to provide ru madreporite 24, on the left and right both ends surface of madreporite 24Sound arresting body 27 this to provide the sound arresting body keep plate 33 which touches, the sound arresting bodyAs for 27 administering the bending which this touches to the front of the exhaust air cutting cylinder 23It is the bend which forms flange 27a and flange 27a and one bodyThe flange joint board 27b which administers processing and to consist of, the furanji 27the exhaust air top 3 armament on the front of the exhaust air opening 29In 0 and co-fasten state the screw it does to stop on the front of the exhaust air cutting cylinder 23,As for flange joint board 27b the moth which this is touched to madreporite 24Sound arresting structure of su hot water supply vessel.
