Abstract
The utility model provides a low-noise gas water heater, which mainly comprises a casing (1), a blower fan (7) and a combustion chamber (4). A porous noise reducing pad (6) made of soundproofing material is arranged between the blower fan (7) and the casing (1). The noise reducing pad (6) is stuck between the blower fan (7) and the rear wall of the casing (1) and is positioned above the air inlet (71) of the blower fan. Preferably, the noise reducing pad (6) is semi-circular or pi-shaped with a downward opening and the thickness of the noise reducing pad (6) is slightly larger than the distance between the blower fan (7) and the rear wall of the casing (1). According to the utility model, the noise reducing pad is additionally provided between the blower fan and the casing of the gas water heater, so that the air is rectified and the noise is reduced. Meanwhile, since the blower fan is supported in a plane manner, the vibration of the blower fan can be prevented and absorbed. The resonance generated during the operation of the blower fan is avoided. Tests show that after domestic rapid gas water heaters are installed with the noise reducing pad, the noise is reduced by over 6 dB during the operation of the gas water heaters.
Description
Technical field
The utility model relates to domestic gas-fired water heater.
Background technology
Domestic gas-fired water heater generally is made up of fuel gas combustion system and water heating system, and wherein combustion system mainly comprises air inlet pipe 8, blower fan 7, combustion chamber 4, heat exchanger 3 and blast pipe 2, and its structure is referring to Fig. 1.Air inlet pipe provides combustion gas, and like natural gas, town gas or liquefied gas, blower fan provides combustion-supporting air, and combustion gas heats water to proper temperature in heat exchanger after combustion chambers burn, supplies to take a shower or other family expenses.Wherein the air outlet of blower fan 7 is fixed on the combustion chamber 4, when equipment moves, because the air-intake turbulent flow of blower fan and mechanical resonance meeting produce very big noise, not only influences complete machine work, also brings influence to the user.
Summary of the invention
The purpose of the utility model is to provide a kind of low noise gas heater; According to blower fan air intake position; Through between blower fan and casing, adding silencing pad, when rectification is carried out in the path that air is got into blower fan, overcome the problem that blower fan is easy to generate resonance; Thereby the noise the during operation of reduction equipment is realized quietization.
A kind of low noise gas heater of the utility model mainly comprises casing, blower fan, combustion chamber, it is characterized in that: between blower fan and casing, be encased inside the noise reduction sound silencing pad of being processed by the acoustic material of porous.
Said silencing pad is pasted between blower fan and the casing rear wall, is positioned at the top of air inlet.This silencing pad semi-round ring shape that preferably Open Side Down or Π shape, its thickness are slightly larger than the distance between blower fan and casing 1 rear wall.
The remarkable result of the utility model is: blower fan is originally from all directions air intake of air inlet, and the easy like this turbulent flow that causes sends noise, is fixed on the casing because blower fan links to each other with the combustion chamber simultaneously, so causes resonance easily.After adding silencing pad, air only gets into blower fan from direction in below of air inlet, has played rectified action; Therefore reduced noise; Simultaneously owing to after being encased inside silencing pad between blower fan and the box back surface, blower fan being supported, and can absorbing the vibration of blower fan; Thereby produce resonance can avoid fan operation the time, further reduced noise.After test family expenses fast gas heater was installed noise reduction sound silencing pad, noise can reduce more than the 6dB during use, and user's environment for use is staticized.

The specific embodiment
Combine an embodiment and accompanying drawing thereof that the utility model is described further at present.
By Fig. 1; Gas heater generally comprises a casing 1; Be provided with fuel gas combustion system and water heating system in the casing, wherein fuel gas combustion system mainly comprises air inlet pipe 8, blower fan 7, combustion chamber 4, heat exchanger 3 and blast pipe 2, and the air outlet 72 of blower fan 7 is connected with combustion chamber 4.Combustion gas is from air inlet pipe 8 entering combustion chambers 4 time, and combustion air blasts combustion chamber 4 by blower fan 7, and the heat that fuel gas buring discharges is through 3 pairs of water heating of heat exchanger, and waste gas after burning is discharged by blast pipe 2.Between blower fan 7 and casing 1, be encased inside by the fire-retardant acoustic material of porous the noise reduction silencing pad of processing like melamine foamed plastic 6.
By Fig. 2 and Fig. 3, blower fan 7 is located at the right lower quadrant of casing, and air inlet 71 is towards casing 1 back side, and air outlet 72 upwards links to each other with combustion chamber 4.Said silencing pad 6 is pasted between top, blower fan 7 and casing 1 rear wall of air inlet 71.After combustion air gets into casing by the air inlet round on the casing 1; Under the suction of blower fan 7; Arrive the air inlet 71 of blower fan downwards, owing to the top of air inlet is blocked by silencing pad, so air-flow can only be other circuitous to the blower fan downside from blower fan; Get into air inlet 71, reduced the noise that turbulent flow sends effectively.
Like Fig. 4 or Fig. 5, said silencing pad 6 semi-round ring shape that preferably Open Side Down or Π shape, its thickness is slightly larger than the distance between blower fan 7 and casing 1 rear wall.Silencing pad 6 supports blower fan from casing one side with planar fashion, and not only can prevent to vibrate can also absorbed oscillation, thereby can effectively prevent the generation of resonating, and reaches the purpose that reduces noise.
Claims (3)
