Abstract
The utility model discloses a fume hood fan part for a strong suction gas water heater, which comprises a fume collecting hood, an exhaust fan and a flow guide hole plate. The exhaust fan is fixed above the fume collecting hood, a gas inlet communicated with the exhaust fan is arranged on the fume collecting hood, and the flow guide hole plate is arranged below the gas inlet of the fume collecting hood. The fume hood fan part aims at overcoming shortcomings in the prior art and is capable of optimizing burning working conditions, improving heat exchange efficiency and reducing burning noise. The fume hood fan part is suitable for household instantaneous gas water heaters or dual-purpose stoves.
Description
[technical field]
The utility model relates to a kind of petticoat pipe fan part that is used for strong odd test gas heater.
[background technology]
Strong in the market odd test gas heater petticoat pipe fan part does not have mounting guiding board, and red-hot air-flow accumulates in exhaust fume collecting hood air inlet below and passes through during machine works, is prone to cause the heat exchanger hot-spot, burns out heat exchanger fin, shortening heat interchanger service life.The combustion chamber internal gas flow is inhomogeneous, and corner, exhaust fume collecting hood both sides is prone to form eddy current, influences normal heat exchange, when ambient humidity is big, is prone to produce condensed water.The acid condensate water of condensing between the heat exchanger fin can be corroded heat exchanger fin and heat exchanger tube, influences service life of a machine and security.The combustion chamber internal gas flow is inhomogeneous, causes that flame is partially elongated, and combustion conditions worsens, and produces noise, increases noxious gas emission, jeopardizes safe in utilization.
The utility model is being made in such cases.
[utility model content]
The utility model purpose is in order to solve the weak point of common petticoat pipe fan part, but a kind of optimized combustion operating mode is provided, and improves heat exchange efficiency, reduces the petticoat pipe fan part of combustion noise.The utility model is applicable to domestic gas instantaneous water heater or dual-purpose stove.
For solving the technical problem of above-mentioned existence, the utility model adopts following technical proposal:
A kind of petticoat pipe fan part that is used for strong odd test gas heater; It is characterized in that including exhaust fume collecting hood, air exhauster and water conservancy diversion orifice plate; Described air exhauster is fixed on the exhaust fume collecting hood top; Exhaust fume collecting hood is provided with the air inlet that is communicated with air exhauster, and described water conservancy diversion orifice plate is located at the below of exhaust fume collecting hood air inlet.
As above described a kind of petticoat pipe fan part that is used for strong odd test gas heater, it is characterized in that said water conservancy diversion orifice plate includes plate body, regular distribution blinds fenestra or through hole on plate body.
As above described a kind of petticoat pipe fan part that is used for strong odd test gas heater, it is characterized in that said blinds fenestra for to stamp out the hole that forms behind the fritter tabs on the flat board, the angle that tabs and plate body bottom surface form is an acute angle.
As above described a kind of petticoat pipe fan part that is used for strong odd test gas heater, it is characterized in that said water conservancy diversion orifice plate is individual layer or bilayer or multilayer orifice plate.
Aforesaid a kind of petticoat pipe fan part that is used for strong odd test gas heater is characterized in that said water conservancy diversion orifice plate is connected on the exhaust fume collecting hood through welding or screw thread or screens.
Described a kind of petticoat pipe fan part that is used for strong odd test gas heater is characterized in that said water conservancy diversion orifice plate and exhaust fume collecting hood are one-body molded.
The utility model compared with prior art has following advantage:
1, the water conservancy diversion orifice plate of the utility model is located at the below of exhaust fume collecting hood air inlet, because the water conservancy diversion orifice plate places the below of exhaust fume collecting hood air inlet, produces the flow-disturbing effect; Change gas flow and flow velocity in the heat exchanger cavities; Impel air-flow even, heat exchanger fin is heated evenly, thereby promotes the heat exchange effect.
2, the exhaust fume collecting hood both sides can not produce eddy current, reduce noise, suppress the generation of condensed water.
3, burner flame can be by not partially elongated, and burning is steady, and noise is little.

Fig. 2 is the work sketch map of the utility model;
Fig. 3 is the work sketch map of common petticoat pipe fan part.
Annotate: the direction of arrow is the gas flow direction among the figure.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in Figure 1, a kind of petticoat pipe fan part that is used for strong odd test gas heater includes exhaust fume collecting hood 1, air exhauster 2, water conservancy diversion orifice plate 3.Described air exhauster 2 is fixed on exhaust fume collecting hood 1 top, and air exhauster 2 is upwards taken out the air-flow of 1 li of exhaust fume collecting hood.Water conservancy diversion orifice plate 3 is located at air inlet 11 belows of exhaust fume collecting hood 1.Described water conservancy diversion orifice plate 3 includes plate body 31, on plate body 31, is provided with regular distribution blinds fenestra or through hole 32.
As shown in Figure 1, the water conservancy diversion orifice plate 3 described in the utility model is arranged on air inlet 11 belows of exhaust fume collecting hood 1, produces the flow-disturbing effect; Change gas flow direction on the one hand; Hot gas no longer accumulates in air inlet 11 lower zones to be passed through, but evenly through heat exchanger 4, can not produce the hot-spot phenomenon; Exhaust fume collecting hood 1 left and right sides edge can not produce eddy current, suppresses the generation of condensed water; Water conservancy diversion orifice plate 3 can slow down air velocity on the other hand, improves the heat exchange effect, and burner flame can be by not partially elongated, flameholding, and noise is little.
As the optimal way of present embodiment, said blinds fenestra 32 is for stamping out the hole that forms behind the fritter tabs on dull and stereotyped 31, and the angle that tabs and plate body 31 bottom surfaces form is an acute angle.
As the optimal way of present embodiment, said water conservancy diversion orifice plate 3 is individual layer or bilayer or multilayer orifice plate.
As the optimal way of present embodiment, said water conservancy diversion orifice plate 3 is fixed on the exhaust fume collecting hood 1 through welding or screw thread or screens.
As the optimal way of present embodiment, said water conservancy diversion orifice plate 3 is one-body molded with exhaust fume collecting hood 1.
As the optimal way of present embodiment, said water conservancy diversion orifice plate 3 is arranged on exhaust fume collecting hood 1 air inlet 11 belows.
The utility model compared with prior art has following difference:
1, the water conservancy diversion orifice plate of the utility model is located at the below of exhaust fume collecting hood air inlet, because the water conservancy diversion orifice plate places the below of exhaust fume collecting hood air inlet, produces the flow-disturbing effect; Change gas flow and flow velocity in the heat exchanger cavities; Impel air-flow even, heat exchanger fin is heated evenly, thereby promotes the heat exchange effect.
2, the exhaust fume collecting hood both sides can not produce eddy current, reduce noise, suppress the generation of condensed water.
3, burner flame can be by not partially elongated, and burning is steady, and noise is little.
