Description
Technical field
The present invention relates to gas heater, refer specifically to a kind of air intake noise-reducing structure for gas heater.
Background technology
At present, consumer is more and more higher to the requirement that gas heater is quiet.Authorization Notice No. is in CN205245564
State's utility model patent discloses " gas heater of a kind of band silencing function ", and it is for taking out by force type or strong drum type structure, in combustion
The back side of gas heater box, side or end face offer air inlet；Air inlet is provided with airscoop shroud, airscoop shroud sets
Having air intake vent, be provided with silencing baffles in airscoop shroud, it is roundabout that outside air enters airscoop shroud tailing edge silencing baffles from air intake vent
Flowing arrives air inlet.This utility model, by arranging airscoop shroud and baffle plate by air roundabout entrance water heater tank body, can be led
Blower fan air intake resistance is big, air demand is not enough in cause, and possible air inlet is smooth, reduces the wind resistance of water heater；And in air capacity not
The when of foot, flameholding to be ensured needs to increase rotation speed of fan, and so fan noise can increase on the contrary.
Summary of the invention
The technical problem to be solved is that the present situation for prior art provides one can significantly improve air intake and make an uproar
Sound also can improve the air intake noise-reducing structure for gas heater of efficiency of combustion.
The present invention solves the technical scheme that above-mentioned technical problem used: this is used for air intake noise reduction knot of gas heater
Structure, it is characterised in that include outer tube and the inner tube being mutually socketed, the gap between described outer tube and said inner tube forms air inlet and leads to
Road；
Wherein, the inner port of said inner tube connects the air vent of the gas skirt of water heater, and the external port of inner tube connects smoke evacuation
Pipeline；
First port of described outer tube connects the air inlet of described water heater, and the second port connection environment of described outer tube is big
Gas, and described second port is provided with filter screen, and the inwall of described outer tube is provided with sound absorbing layer.
The aperture of described filter screen is preferably 2～16mm.This structure can either meet the requirement filtered with noise reduction simultaneously.
The structure of described sound absorbing layer can have multiple, and preferably, described sound absorbing layer is silencing cotton.This structure is simpler, and
Raw material is cheap and easy to get.
As improvement, in above-mentioned each scheme, on the end face of the casing that described air inlet can be arranged on described water heater；Institute
State air vent to be arranged on the end face of described exhaust fume collecting hood.Conventional method is the back of the body of the casing that air inlet is arranged on water heater
On face, to metope, metope will not absorb acoustic energy, and noise spreads out of from air inlet, direct incoming human ear；Further, heater box
And hole is narrow and small between body of wall, air circulating resistance is big, and air flow is relatively more random, causes fan noise big.And this structure, hot water
Device casing fully seals, and air-flow enters water heater from top, and obstacle is few, and air intake passage is smooth and easy, and resistance is little, substantially improves wind
Machine air intake environment.Blower fan is under uniform air intake environment, and own efficiency is higher, noise is lower.
The width of the most described inlet channel is 8～20mm.
The thickness of described sound absorbing layer is 2～5mm.
Preferably, said inner tube can use the metal material of heat conduction to prepare.Inner and outer tubes in this structure are formed and change
Hot device, utilizes the cold air that flue-gas temperature preheating enters, thus efficiency of combustion and the thermal efficiency are energy-saving and cost-reducing.
Compared with prior art, the air intake noise-reducing structure for water heater provided by the present invention, by the casing of water heater
Be designed as closing structure, control overwhelming majority noise and spread out of from inlet channel, noise in communication process through silencing cotton, filter screen
Deng denoising structure, inherently reducing fan noise, noise reduction is notable；Further, inner tube, outer tube sleeve are connected on one by the present invention
Rise, utilize the flue-gas temperature of waste to preheat cold air, improve efficiency of combustion and the thermal efficiency of combustion gas, energy conservation and consumption reduction effects
Good；The present invention the most also has simple in construction, advantage easy for installation.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figures 1 to 4, this air intake noise-reducing structure being used for gas heater includes:
Inner tube 2, for the discharge flue of water heater, uses the metal material of heat conduction to prepare, and its inner port connects water heater 3
The air vent of gas skirt 31, the external port of inner tube 2 connects smoke discharging pipe 4；In the present embodiment, the aperture of inner tube 2 is 60mm.
Outer tube 1, for the air inlet pipe of water heater, is set in outside inner tube 2, and the aperture of the present embodiment middle external tube 1 is 95mm；Outer tube
Gap between 1 and inner tube 2 forms inlet channel 5, and the width of inlet channel is 12.5mm.
First port of outer tube 1 connects the air inlet 32 of water heater 3, and the second port 11 of outer tube 1 connects ambient air, the
Two-port netwerk 11 is provided with filter screen 12, and the aperture of filter screen is 10mm, and the inwall of outer tube 1 is provided with sound absorbing layer 13, and the present embodiment uses
Acoustical cotton, the thickness of sound absorbing layer is 5mm.
In the present embodiment, the air inlet 32 of water heater 3 is arranged on the end face of casing 33 of water heater；Air vent is arranged on
On the end face of exhaust fume collecting hood 31.
When water heater 3 works, surrounding air enters inlet channel 5 via filter screen 12, and filter screen 12 intercepts impurity and enters hot water
Device；After air enters heater box, enter burner through blower fan and burn with combustion gas mixing, flow heated water.Wind is entered at air
On the path of machine, hinder thing few so that the fan noise as water heater maximum noise source reduces.
And owing to water heater eliminates the air inlet at the cabinet back side, the noise overwhelming majority that whole water heater produces can only
Spread out of from top, through the decay of bend pipe, silencing cotton, the Noise Reduction of wire netting, and distance sound self, incoming human ear
The more conventional water heater of noise much lower.After tested, during the work of gas heater peak load, sound pressure level reduces 5-7dB
(A), represent that the average acoustic power level of parameter of sound source self vocality reduces 5.6dB (A).Illustrate that the present invention inherently reduces
The noise of gas heater.
The flue gas with uniform temperature that fuel gas buring produces is discharged from the air vent of exhaust fume collecting hood, enters row via inner tube 2
Outside smoke pipeline 4 discharge chamber；High-temperature flue gas is while inner tube flows, and with the cold air heat exchange in inlet channel, cold air is high
Temperature flue gas, the mixing of hot-air and combustion gas evenly, improves combustion rate and the thermal efficiency of combustion gas, makes full use of and be wasted
The heat energy fallen, improves the efficiency of water heater ".
