As further illustrating of such scheme, described noise reduction baffle plate is divided into airscoop shroud to be interconnectedThe first cavity and the second cavity, the connected entrance of the first cavity and the second cavity is positioned at one end of noise reduction baffle plate,Air intake vent and air inlet are communicated with the first cavity, the second cavity respectively, and are disappeared between air intake vent and air inletSound baffle plate separates.
As further illustrating of such scheme, described noise reduction baffle plate be metal baffle, ceramic baffle plate orRubber baffle, is provided with muffle coating on the surface of noise reduction baffle plate.
As further illustrating of such scheme, described airscoop shroud is square shade, and airscoop shroud is installed to combustionAfter on gas water heater, each side of airscoop shroud is concordant with gas heater respective side; Described sound gobo embeddingIn airscoop shroud and with three sidewalls of airscoop shroud, seal.
As further illustrating of such scheme, described air intake vent and air inlet are all by multiple bar hole groupsBecome.
As further illustrating of such scheme, described airscoop shroud is metal cap, at the interior table of airscoop shroudFace is provided with muffle coating.
Compared with prior art, the beneficial effects of the utility model are:
One, by airscoop shroud is set, a kind of brand-new gas heater intake method is proposed, be combustion gasWhen water heater provides air, stop the outside discrepancy of sound wave, reduce gas and hot water from the propagation of noiseThe use noise of device.
Two, the setting of airscoop shroud, has changed the intrinsic frequency of gas heater complete machine, avoids combustion oscillationGeneration, fundamentally solved and avoided forced-ventilated or take out by force that type gas heater combustion noise is large, balancing machineThe problems such as easy resonance, the noise while making gas water heater working is effectively reduced.

Detailed description of the invention
Understand better essence of the present utility model for convenience of those skilled in the art, below in conjunction with accompanying drawingDetailed description of the invention of the present utility model is described in detail.
As shown in Figure 1, a kind of gas heater air inlet method, is characterized in that, is taking out by force type or is rousing by forceOn type gas heater air inlet, increase air inlet runner 1-1, utilize air inlet runner 1-1 to stop gas heaterInner noise outwards spreads out of, and reduces the use noise of gas heater from the propagation of noise.
Particularly, outwards to spread out of be by by air inlet runner to the noise of described prevention gas heater inside1-1 air intake vent 1-2 and gas heater air inlet 1-3 stagger to realize. In the present embodiment, preferably staggerMethod is: between air inlet runner air intake vent 1-2 and gas heater air inlet 1-3, a baffle plate 1-4 is set; OutwardBoundary's air from air intake vent enters air inlet runner along a side flow of baffle plate 1-4 and travel back across air inlet 1-3.
For obtaining better erasure effect, described air inlet runner 1-1 and/or baffle plate 1-4 are noise reduction knotStructure. Such as, all adopt quieter material to make air inlet runner 1-1 and/or baffle plate 1-4; Or at air inlet runner1-1 inner surface and/or baffle plate 1-4 outer surface coating sound deadening coating, the material of air inlet runner and baffle plate can be:Metal, timber, pottery or rubber etc.
As shown in Figure 2, it provides a kind of gas heater based on above-mentioned air inlet method, this gas and hot waterDevice, for taking out by force type or strong drum type structure, offers air inlet 2-2 at the back side of gas water-heater housing 2-1,Airscoop shroud 2-3 is installed on air inlet 2-2, on airscoop shroud 2-3, is provided with air intake vent 2-4, in airscoop shroud 2-3Noise reduction baffle plate 2-5 is installed, and outside air is circuitous along noise reduction baffle plate 2-5 from air intake vent 2-4 enters airscoop shroud 2-3The moving air inlet 2-2 that arrives refluxes.
Shown in Fig. 3, described air inlet 2-3 and air intake vent 2-4 are made up of multiple bar holes. DescribedNoise reduction baffle plate 2-5 is divided into airscoop shroud 2-3 the first cavity A and the second cavity B that are interconnected, the first cavity ABe positioned at one end of noise reduction baffle plate 2-5 with the connected entrance of the second cavity B, air intake vent 2-4 and air inlet 2-2 respectively withThe first cavity A, the second cavity B are communicated with, and are separated by noise reduction baffle plate 2-5 between air intake vent 2-4 and air inlet 2-2.
More specifically, described airscoop shroud 2-3 is square shade, and airscoop shroud 2-3 is installed to gas heater shellAfter body 2-1 is upper, each side of airscoop shroud 2-3 is concordant with the respective side of gas water-heater housing 2-1; Described disappearingSound dividing plate 2-5 is embedded in airscoop shroud 2-3 and with three sidewalls of airscoop shroud 2-3 and seals.
When real work, air supply enters the first cavity A by air intake vent 2-4, and along noise reduction baffle plate2-5 one-way flow enters the second cavity B, then enters water heater complete machine inside by air inlet 2-2, mixed with combustion gasAfter combination burning, discharged by smoke exhaust pipe 2-6.
Compared with prior art, a kind of gas heater that the present embodiment provides, is ensureing air inlet supplyCondition under, stoped outwards spreading out of of inner sound wave; Meanwhile, arranging of airscoop shroud changed gas and hot waterThe intrinsic frequency of device complete machine, avoids the generation of combustion oscillation; Efficiently solve forced-ventilated machine or strong pump combustion noiseGreatly, the easily problem such as resonance of balancing machine, noise when reduction gas water heater working.
Above detailed description of the invention has been described in detail essence of the present utility model, but can not be withThis limits protection domain of the present utility model. Apparently, opening in the utility model essenceUnder showing, the art those of ordinary skill also can carry out many improvement and modification, such as air inlet is changed intoBe arranged on top or the side of gas water-heater housing. It should be noted that these improvement and modify and all drop onWithin claim protection domain of the present utility model.
