The utility model is composed of a housing (1), an ignitor (2), an air controlled device (3), a water controlled device (4), a water section (5), a main burner (6), a heat exchanger (7), a flameout safeguard device (8), a metallic screen cover (9) and a reflecting arrangement (10). The utility model has the advantages of fast burning speed, high burning temperature, high heat efficiency, gas saving, stable fire behavior, no limitation of low temperature environment, no pollution to environment and favorable sanitary condition; under the same load, the utility model can save combustion gas about 30% compared with other gas water heaters.

Description

Economize the gas high-temperature water heater

The utility model relates to a kind of domestic gas-fired water heater tool.

Gas heater is that a kind of heat energy that sends when utilizing fuel gas burings such as natural gas, town gas, liquefied petroleum gas heats cold water.Domestic gas-fired water heater is extensive use, and product is seriation, and is various in style, and performance is more and more advanced.Structurally, typical fast water heater generally comprises shell, igniter, gas control device, water-control device, aqueous vapor linkage, main burner, heat exchanger, flame-out safety guard.When combustion gas, is carried out mixing the first time with outside air during with certain speed ejection from the nozzle of burner, combustion gas and Air mixing gas behind spark ignition, carry out mixing the second time with air when the fire hole of main burner head is emerged.Because the component of combustion gas of the same race is more or less different, the appropriate mixed proportion of they and air should constantly be adjusted at any time, just can make fuel gas buring complete.But, when Actual combustion, can not regulate relative assembly at any time, make burning be in optimum state, the stink of combustion gas is arranged in the air unavoidably.Thereby, make the fuel gas buring in the existing gas heater be in optimum state at any time, improve the thermal efficiency, both economized gas, high temperature again reduces environmental pollution still there's sth behind all this and can do.

The purpose of this utility model be intended to design a kind ofly be in optimal combustion state, temperature height at any time, economize gas, domestic gas-fired water heater free from environmental pollution.

The technical solution adopted in the utility model is: cover adds cellular metallic screen cover on main burner, in the bottom of main burner reflection unit is installed.When through the first time, the combustion gas that mixes for the second time and Air mixing gas combustion, it during beginning blue flame, about about 800 ℃ of its temperature, under the blue flame effect, the metallic screen cover heats up, and blue flame disappears, and is converted into the scorching hot visible light and the thermography line of 300,000,000 meters speed of per second, all flammable compositions in the combustion gas are able to completing combustion under the high temperature action of sieve cover, make the temperature of combustion zone remain on the condition of high temperature about 1300 ℃.The reflector of main burner bottom increases the temperature in the device with the upwards reflection of heat of downward radiation.Simultaneously, radiation reflected heat makes the air mixture expanded by heating that enters in the skirt of main burner bottom, causes being able to continuously from the combustion gas of fire hole ejection, has solved the jet interrupted defect of gas heater fire hole under the low temperature environment.

The major advantage of the gas heater of the utility model design is: burning velocity is exceedingly fast, completing combustion at any time, and not only combustion zone temperature height, and the thermal efficiency is also high; Economize gas, under identical thermic load, save combustion gas about 30% than other gas heater; The intensity of a fire is stable, is not subjected to the limitation of low temperature environment, environmentally safe, health.

Fig. 1 is the utility model structural representation.As shown in the figure, the utility model is made up of shell (1), igniter (2), gas control device (3), water-control device (4), aqueous vapor linkage (5), main burner (6), heat exchanger (7), flame-out safety guard (8), metallic screen cover (9), reflection unit (10).The movable upper shield of metallic screen cover (9) and covers whole fire holes on the fire hole of main burner (6), and reflector arrangement (10) is parabolic shape, is installed in the below of main burner (6).

Claims (2)

1, economizes the gas high-temperature water heater; form by shell (1), igniter (2), gas control device (3), water-control device (4), aqueous vapor linkage (5), main burner (6), heat exchanger (7), flame-out safety guard (8), metallic screen cover (9), reflection unit (10); it is characterized in that upper shield metallic screen cover (9), metallic screen cover (9) cover whole fire holes on the fire hole of main burner (6), reflection unit (10) is installed in the below of main burner (6).

2, the province gas high-temperature water heater who narrates according to claim 1 is characterized in that being covered with aperture on the metallic screen cover (9), is cellular, and reflection unit (10) is a parabolic shape.
