Abstract
The utility model relates to a domestic totally enclosed gas combustion water heater, composed of a burner, a heat exchanger, a water delivery pipe, an ignition switch, a water-air linkage valve, etc. The utility model is characterized in that the utility model comprises a housing used for wrapping and sealing the burner and a fan mouth which is arranged on the housing; an enclosed lateral wall is made of more than one layer of the metal water-jacket is arranged at the periphery of the lateral upper part of the burner; a combustion chamber on the right top of the burner is provided with multiple heat exchange water pipes; a communicating pipeline is arranged on the heat exchanger which is composed of the metal water-jacket and the heat exchange water pipes; the water heater is provided with a sealed smoke vent outward. The utility model has the advantages that the utility model can more efficiently heat flowing water, and then the waste gas can be exhausted from the smoke vent without leaking the waste gas into the room from any part of the smoke vent, which can ensure safe burning. The utility model has the advandage of higher heat efficiency of the burning.
Description
The utility model relates to a kind of domestic gas-fired water heater.
Be the gas heater that widely uses in the life now, with oil gas, artificial coal gas, natural gas is a fuel, be indispensable home appliances, the structural feature of existing gas heater such as following, comprise ignition switch and aqueous vapor interstage valve, burner and heat exchanger, heat exchanger generally is the copper pipe that fin is housed, copper pipe constitutes water delivery and heat tunnel, because the burner of existing water heater is to transport to burner combustion again by air freedom and combustion gas mixing, can not water heater is totally-enclosed, even flue gas exhausting type installation requirement and corresponding pipeline are arranged, still can not be with the water heater lower seal, so this water heater in use still has insecurity, for example efflux a mouthful down draught; When extinguishing such as flame-out protection device when inoperative, then combustion gas is excessive; When using in the winter time in addition, because undue sealing, the anoxic in whole room caused the generation of fatal accident when the long period used.In addition, the water heater of making the above specification of 7-8l/min also has some difficulties, and is not high as the thermal efficiency, and the waste gas outlet of existing various water heaters is all taken away a large amount of heats, consume too much metal material or the like.
The utility model purpose provides a kind of water heater of totally enclosed active air intake, not only has high security, and thermal efficiency height, and the efficiency of combustion height is made the water heater of big flow specification easily.
Technical solution of the present utility model is as follows: comprising burner, heat exchanger, water-supply-pipe, compositions such as ignition switch and aqueous vapor interstage valve, it is characterized in that comprising that envelope wraps up in the shell of burner and open blower fan mouth on this shell, at least make closed side wall with the layer of metal water jacket in burner side surrounding, the combustion chamber is equipped with many heat exchanging water pipes directly over the burner, the heat exchanger that metal water jacket and heat exchanging water pipe constitute has connecting pipeline, on water heater, be provided with the outside exhaust opening of sealing, the combustion chamber is connected with exhaust opening, described burner comprises that section is the burning bowl of U-shaped, bowl is furnished with aperture, the bowl end, have the combustion gas inlet pipe, and blast orifice leaves at shell upper in the sidepiece or the side lower part of burning bowl.Characteristics of the present utility model are: after the forced air inlet of blast orifice and the combustion gas mixing in the combustion chamber internal combustion, can heat flowing water more efficiently, waste gas is discharged from exhaust opening then, can not leak in indoor from any part, guarantee safe combustion, combustion thermal efficiency is also higher, and the utility model and the conventional family expenses air suspended type water heater result that makes comparisons is as follows:
Air consumption (kilogram/hour) discharge (rise/minute) conventional water heater 1.2 8 78 the utility model 0.9 8 85 of the thermal efficiency (%)
The utility model is described in further detail below in conjunction with accompanying drawing with by embodiment:
Fig. 1 is the utility model structural representation (cutaway view)
The heat exchanger that the burner assembly 8 of bottom and envelope are wrapped up in formations such as the combustion chamber, water jacket on the shell 12 of burner and top is tightly connected by flange 5, gas inlet pipe 7 puts in the bottom center of U-shaped burning bowl from outer casing bottom, on the air inlet pipe of burning bowl, be provided with the gas spray head 6 that has burner port, on side wall of outer shell, have blower mouth 11, be attached with the blower fan of 15-40W at blower mouth, 9 is ignition switch and aqueous vapor interstage valve.The sidewall of combustion chamber of burning bowl top is an inner layer metal water jacket 13, be provided with many group outlet pipes 4 directly over the burner, but the set metal fin is used to increase endotherm area on the outlet pipe, and the floss hole of internal layer water jacket up.In order further to improve the thermal efficiency, the utility model can be provided with the outer water jacket of the second layer, and between outer water jacket and ground floor internal layer water jacket, constitute exhaust gases passes, (the stain background is combustion chamber and exhaust gases passes among the figure), exhanst gas outlet is located at the middle and lower part of outer water jacket, the metal water jacket can form water jacket samdwich in whole circumference, also can form water flow passage at the part area of circumference or have the heat absorption sidewall that many water flow passage constitute.The shape of the shape of water jacket certainly,---cross section can be circle, rectangle (band fillet) or ellipse etc.Inlet channel connects with following path, connect burner top main heat exchange pipe again through the internal layer water jacket again from outer water jacket earlier, so outer water jacket water earlier with the flue gas heat exchange internal layer water sleeve main heat exchange pipe of flowing through again, can have the higher thermal efficiency, under this better scheme, the thermal efficiency is not less than 90%.Export flue gas this moment also is the quite low flue gas of temperature, and outlet is directly led to outdoor.Because the pressure of blower fan promotes, guaranteeing that flue gas does not loose leaks in indoor and fully exchanged heat by water jacket.General outside wind pressure is always less than the air blast blast; yet flue gas does not fall to leak in order further to guarantee to shut down; can between air blast and air blast air inlet, the chip check valve be installed; its structure is that valve block end in pipeline connects a pivot or rotates in tube wall; the other end has a supporting station, only opens to the air intake direction with the protection valve block.
