Abstract
The utility model relates to an air exhaust device of a gas water heater. The utility model solves the problem that external air is inversely filled to blow out gas naked fire. The utility model is characterized in that the middle segment of a frame body is shrunk in an inclined mode and then upwards extended; the lower inner side end surface of the top end namely the back side end surface of the upper half segment has a slotted hole; an air guide plate which is arranged on the top end of the frame body is a flaky body which is arranged in an upwards inclined mode like a parabola. Besides, a fixing bracket is fixedly arranged on both sides of the shrinkage part of the middle segment of the frame body, the back end of the fixing bracket is provided with fixing part which can male the entire frame body attached fixedly to the wall and the slotted hole and the back side of the air guide plate keep a fixing distance away from the wall. The utility model can be used for the gas water heater.
Description
The utility model relates to water heater, refers to a kind of air exhausting device of gas water heater especially, i.e. the said exhaust duct of the utility model.
Existing general gas-fired water heater is for preventing that coal gas from producing carbon monoxide human body is damaged when burning, water heater can be provided with on the balcony that ventilates preferably, to prevent unexpected generation, and the balcony of general occupants of building is most in the higher position, so wind-force is stronger, and wind direction is not really fixing, so the body top of gas water heater as shown in Figure 3, generally is provided with exhaust outlet, so that the rising hot gas during gas-fired is drained.But this kind project organization under the random landscape condition of high wind, often has high wind to pour in down a chimney and go into from exhaust outlet, even blows out stove fire, the dangerous situation that causes coal gas to leak.So the kind air discharge structure, reality has necessity of redesign.
The purpose of this utility model is exactly through research and experience accumulation for many years, provides a kind of through improved water heater exhaust duct with the above-mentioned shortcoming that overcomes the gas water heater exhaust apparatus.
The purpose of this utility model is achieved in that the water heater exhaust duct, comprises framework, wind deflector and fixed support, and the framework bottom is sheathed on water heater fin top, it is characterized in that the framework stage casing slopes inwardly to extend upward after shrinking; Inner side end under the top that is to say to dig at upper semisection rear side end face to be provided with a slotted eye; Wind deflector is positioned at the framework top, is then to be the plates that parabola is inclined upwardly and is provided with by preceding; Fixed support system is fixedly arranged on the and arranged on left and right sides of contraction place, framework stage casing, and its rear end is provided with and can makes whole framework be posted solid in wall slotted eye and wind deflector rear side then keep a fixed range with wall fixed part.
Above-mentioned design, when hot blast by the framework bottom when rising to wind deflector, by the guiding of wind deflector, hot blast can be emitted by slotted eye, and high wind from top to bottom, then can be by the wind deflector dispersive pressure, the slotted eye that the indefinite random wind of direction also can't face wall certainly pours into, to guarantee normal safe combustion.
Below by drawings and Examples the utility model is described further again:
Fig. 1 is the utility model structural upright schematic diagram.
Fig. 2 flows to schematic diagram for the utility model side-looking and wind direction, thermal current.
Fig. 3 is the structural perspective of existing water heater exhaust duct.
Mark among the figure: 1 framework, 2 wind deflectors, 3 fixed supports, 4 water heater fin, 11 slotted eyes, 31 fixed parts.
User mode of the present utility model as seen from the figure: when the burning gas water heater, the hot gas that rises enters the framework bottom through fin, make the framework bottom be formed into the air port, thermal current continues upwards when running into the wind deflector that intercepts in the framework top, can overflow by slotted eye by the guiding of wind deflector, make slotted eye form exhaust outlet, to reach the purpose of air draft; And since as the slotted eye of exhaust outlet towards wall, the coal gas stove fire is gone into to put out by institute so that the high wind sinuous flow is difficult for pouring in down a chimney, air-flow from top to bottom then can be by being parabolical wind deflector flow-disturbing, wind-guiding, and can lower blast, can prolong the service life of the water heater that hangs on wall.
