A kind of gas heater, including exhaust fume collecting hood and the blower fan installed in exhaust fume collecting hood upper end, the exhaust fume collecting hood include air intake
Mouth and air outlet, install the blower fan on the air outlet end face, and the air outlet end face has certain with air inlet end face
Angle, the axle of the blower fan is vertical with air outlet end face, and blast pipe, the blast pipe have been radially arranged in the spiral case of the blower fan
It is connected with smoke exhaust pipe.
Further：The smoke exhaust pipe is divided into connecting portion and bending part, and the connecting portion is connected with blast pipe, where connecting portion
The angle that axis is formed with bending part axis is a.
Further：The angle that the air outlet end face is axially formed with air inlet is b, and a is mutually identical with b sizes.
Further：The air outlet size and fan leaf internal diameter sizableness, the blast pipe are located at flabellum rear portion.
Further：The bending part axis is parallel with air inlet axis.
Further：Connect and fix using anchor ear between the connecting portion of the blast pipe and smoke exhaust pipe.
Further：Sealing structure is provided between the blast pipe and the connecting portion.
Exhaust fume collecting hood described further upwardly extends from air inlet, and right-hand end development length is more than left-hand end development length, shape
It is mutually inclined into air outlet end face and air inlet end face.
Beneficial effect
The beneficial effects of the invention are as follows：By the way that the air inlet of exhaust fume collecting hood is made and air outlet is in a certain angle is hung down and blower fan
Directly in air outlet, the problem of causing air inlet wind speed profile inequality because of blower fan exhausting can be reduced, and cause enclosure whirlpool
It is small to flow area, so as to avoid the problem of water heater partial combustion deteriorates, this is simple in construction, while reducing amount of parts
Cost of manufacture is reduced, extends service life.
Brief description of the drawings
Fig. 1 is the structural representation of water heater exhaust fume collecting hood and blower fan of the present invention
Embodiment
As one embodiment of the present invention, as shown in figure 1, a kind of gas heater, including exhaust fume collecting hood 2 and it is arranged on
The blower fan 8 of exhaust fume collecting hood upper end, the exhaust fume collecting hood 2 include air inlet 1 and air outlet 9, air inlet are provided with flange and water heater
Shell is fixed by screw, and air inlet is connected with the heat exchanger of water heater upper end, and the wind is installed on the air outlet end face
Machine, blower fan are fixed by screw with air outlet end face by screw, and the air outlet end face is with air inlet end face formed with certain
Angle, that is, air inlet axis intersect with air outlet axis, and the axle of the blower fan is vertical with air outlet end face, in the blower fan
Spiral case 10 be radially arranged blast pipe, the blast pipe is connected with smoke exhaust pipe, and the flabellum of the blower fan is located in spiral case, described
Spiral case is cylindrical, and the blast pipe is provided with spiral case side wall, and blast pipe is connected with the smoke exhaust pipe by way of anchor ear 3
Connect, sealing structure is provided between blast pipe and the connecting portion of smoke exhaust pipe, the sealing structure is O-ring seal, can be prevented
Flue gas overflows between blast pipe and connecting portion.It is in a certain angle with air outlet by the way that the air inlet of exhaust fume collecting hood is made,
And blower fan can reduce the problem of causing air inlet wind speed profile inequality because of blower fan exhausting, and cause perpendicular to air outlet
Exhaust fume collecting hood vortex diminishes, and so as to avoid the problem of water heater partial combustion deteriorates, this is simple in construction, reduces component number
Cost of manufacture is also reduced while amount, extends service life.
In the present embodiment：The smoke exhaust pipe is divided into connecting portion 4 and bending part 6, and the connecting portion is connected with blast pipe, connection
The angle that axis 5 where portion is formed with bending part axis 7 is a, and the angle is 110 °, and the angle is equal for the wind speed of air inlet
It is even preferably, the problem of avoiding burner combustion inequality.Smoke exhaust pipe is divided into connecting portion and bending part, and the axis of connecting portion with
The axis of blast pipe is located on same axis, and it is a that the axis of the axis of bending part and connecting portion, which is crossed to form angle, bending part
The problem of air inlet formation wind speed inequality causes water heater combustor combustion position inequality is reduced after contributing to blower fan exhausting.
In the present embodiment：The angle that the air outlet end face is formed with air inlet axis is b, and a is identical with b sizes,
Here connecting portion axis is parallel with air outlet end face, angle b and connecting portion axis and bending part axis with air inlet axis
Angle it is identical, this contribute to reduce blower fan exhausting rear air inlet wind speed inequality the problem of, can reduce exhaust fume collecting hood vortex, help
In the combustion even of water heater combustor, so as to extend water heater service life, while pass through strict Digital Simulation and experiment
The result, exhaust fume collecting hood air inlet wind speed uniformity is good, and vortex reduces, and the fired state stable and uniform of water heater combustor,
Partial combustion impaired condition is improved, and helps to increase the service life.
In the present embodiment：The air outlet size and fan leaf internal diameter sizableness, after the blast pipe is located at flabellum
Portion.Fan leaf is located in spiral case, and blast pipe with being connected in spiral case, take out by the gas after water heater combustor is burnt in flabellum rotation
Smoke exhaust pipe is sent to by blast pipe after going out, such case equivalent to will blower fan exhausting extract out after get rid of to blast pipe so that flue gas edge
Volute of blower is radially thrown away, the problem of being favorably improved the speed of fume emission and reduce the vortex of flue gas formation.Simultaneously will
Air outlet and fan leaf internal diameter are made that size is identical more to be contributed to reduce the formation being vortexed, and reduce exhaust fume collecting hood air inlet wind speed
The problem of skewness, so as to improve water heater combustor combustion case, the problem of burner combustion deteriorates is reduced, is extended
Water heater service life.
In the present embodiment, the bending part axis is parallel with air inlet axis.By bending part axis and air inlet axis
It is made parallel so that the axis of bending part and air inlet has corresponding angles with respect to the spiral case radial direction of blower fan, and that is to say to arrange
Smoke pipe and the flue gas flow direction after air inlet dislocation with equidirectional, so as to reduce, exhaust fume collecting hood air inlet wind speed profile is uneven to ask
Topic, while the size of bending part diameter of section can be adjusted, the loss of bending part wind speed is reduced, that improves blower fan effectively utilizes wind
Amount, improve complete machine wind resistance.
In the present embodiment, as shown in figure 1, the exhaust fume collecting hood upwardly extends from air inlet, right-hand end development length is more than a left side
Side development length, form air outlet end face and be mutually inclined with air inlet end face, form air inlet end face and prolong with air outlet end face
Intersect after stretching, shape is at a certain angle.Contribute to the setting of air inlet and air outlet, and make it that the structure setting is simple, it is convenient.
