Abstract
The utility model relates to an exhauster for a domestic gas water-heater, comprising an outer cover, a motor, a cooling impeller, and an exhaust wheel, wherein, the outer cover is provided with a smoke inlet and an air outlet; the motor, the cooling impeller, and the exhaust wheel are arranged in the outer cover; the bottom of the outer cover forms a convex ring-shaped face; the edge of a circle of a flue group is arranged on the central part of the ring-shaped face; the edge of the flue group forms the smoke inlet whose diameter is between 80 mm and 120 mm. The exhauster of the utility model is suitable for a plurality of gas water-heaters with different types and different standards, which can exhaust waste gas effectively.
Description
The utility model relates to a kind of air exhausting device, particularly is applicable to the exhaust blower of water heater.
At present, as domestic gas-fired water heater, especially Flue Gas Water Heater, in use, the waste gas that burning is produced, can not effectively be forced to discharge outdoor, when running into wind, also can produce negative pressure, waste gas can not be discharged smoothly, cause the indoor pernicious gases such as carbon monoxide that have, human body is caused damage.
The purpose of this utility model is overcoming above-mentioned defective, proposes a kind of air exhausting device of forcing to get rid of all size Flue Gas Water Heater burnt gas, avoids pernicious gas in indoor retaining.
The utility model is to realize like this, it comprises outer cover, motor, cooling wheel, air draft wheel, wherein outer cover is provided with into mouth and air outlet, motor, cooling wheel and air draft wheel are arranged in the outer cover, the bottom of outer cover is the ring surface of a projection, fix a circle flue group limit at the middle part of ring surface, this flue group limit forms into mouth, and the diameter that advances mouth is between 80mm to 120mm.Air outlet is square, and air outlet is fixed a windguard outward, and the end that windguard links to each other with air outlet is square, and the other end is circular or square outlet flue, and an anti-down aerofoil is installed in windguard.The outer cover cross section is an octagon.
Adopt the utility model, it is installed in the top of water heater, cooling wheel and air draft wheel are under the drive of motor, the waste gas of water heater generation or the coal gas of incomplete combustion are sucked by advancing mouth, force to discharge by outlet flue, outlet flue and smoke discharging pipe join, and waste gas drains into outdoor through smoke discharging pipe, designed advance the gas heater of mouth shape applicable to various model different sizes; And the anti-down aerofoil of installing at the outlet flue place, can prevent to produce negative pressure, and prevent in the outdoor cold air inlet chamber; Outer cover is the octagonal of rule, compact conformation not only, and volume is little and handsome in appearance.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is that the B of Fig. 1 is to partial view
Referring to Fig. 1, the utility model comprises outer cover 1, motor 2, cooling wheel 3, air draft wheel 4, and wherein outer cover 1 is provided with into mouth 5 and air outlet 6, and motor 2, cooling wheel 3 and air draft wheel 4 are arranged in the outer cover 1.Referring to Fig. 2, the bottom of outer cover 1 is the ring surface 7 of a projection, fixes a circle flue group limit 8 at the middle part of ring surface 7, and this flue group limit 8 forms advances mouth 5, and the diameter that advances mouth 5 is 100mm.Air outlet 6 is square, fixes a windguard 9 outside the air outlet 6, and the end that windguard 9 links to each other with air outlet 6 is square, and the other end is circular outlet flue 10, and an anti-down aerofoil 11 is installed in windguard 9.The cross section of outer cover 1 is an octagon.
The utility model in use, it is installed in the top of water heater, dock with the outlet flue of water heater on the flue group limit 8 of bottom, if the diameter of water heater outlet flue advances the diameter of mouth 5 less than the utility model, then in flue group limit 8, place a sealing ring, water heater is docked with the utility model sealing; Otherwise, if the diameter of water heater outlet flue advances the diameter of mouth 5 greater than the utility model, then flue group limit 8 outside, place a sealing ring, the realization water heater docks with sealing of the present utility model.So just guaranteed that the utility model can fully be applicable to the water heater of various bores.
