Abstract
The utility model discloses a kind of blower fan and the combustor portion of burner one fills, it is characterised in that including：Housing, burner and blower fan, the housing includes the first interconnected cavity, the second cavity, the upper and lower sides of first cavity are all hatch frame, the burner is arranged in the first cavity, the air flow channel that section is in J-shaped is formed between the shell of burner and the first cavity inner wall, the air outlet of air flow channel is located at the bottom of burner；The assembling is provided with impeller in the second cavity on blower fan, and air inlet is provided with the second cavity.Combustor portion dress compact provided by the utility model is compact.During real work, the air of blower fan suction fills through air inlet into combustor portion, and flows to the air flow channel of housing both sides, because the air outlet size of air flow channel is smaller.Larger air capacity and less air outlet so that the wind speed of air outlet is larger, and Reynolds number is smaller, and wind speed is highly stable with air quantity.
Description
Technical field
It the utility model is related to fluid heater burner arts, more particularly to a kind of blower fan and the combustion of burner one
Burner portion fills.
Background technology
Forced exhaust formula gas heater is to carry out forcing air draft or forced-air blast using blower fan, and combustion product gases are discharged
To outdoor, the sanitation and hygiene of room air are kept, avoid the intoxication accident of CO in flue gas, security is good.
But there is also following shortcoming in use for forced exhaust formula gas heater：1) blower fan is to separate with burner
, larger space internally is occupied in topology layout, if the performance of blower fan and burner can be influenceed by reducing size again, so
Development of the gas heater to compact and frivolous direction is restricted.2) because combustor portion dress inner flow passage is larger, and wind
The air outlet of machine is smaller so that the wind-force near fan outlet is larger, and the wind-force away from fan outlet is smaller, easily occurs
A is vortexed, and internal wind-force and wind direction are uneven at work for gas heater, as shown in Figure 1.
Utility model content
For problems of the prior art, the purpose of this utility model be to provide a kind of compact, wind direction with
The uniform combustor portion dress of wind speed.
To achieve the above objectives, the utility model adopts the following technical scheme that.
A kind of blower fan and the combustor portion of burner one fill, it is characterised in that including：Housing, burner and blower fan, institute
Stating housing includes the first interconnected cavity, the second cavity, and the upper and lower sides of the first cavity are all hatch frame, the burner
The air flow channel that section is in J-shaped, air stream are formed in the first cavity, between the shell of burner and the first cavity inner wall
The air outlet in road is located at the bottom of burner；The assembling is provided with impeller, in the second chamber in the second cavity on blower fan
Body is provided with air inlet.
As with improvement, first cavity, the second cavity are arranged side by side, respectively positioned at the left and right sides of housing.
As with improvement, the air flow channel is distributed at least both sides of burner.
As with improvement, the slit width of the air flow channel air outlet is 0.5-3mm.
As with improvement, the air inlet is arranged on the side or rear of impeller.
The beneficial effects of the utility model are：
First, blower fan and burner share a housing, and blower fan and burner are integrated, and have simplified the combustion of forced exhaust formula
The internal structure of gas water heater, it is developed to compact direction, significantly reduce cost.
2nd, by forming the air flow channel that section is in J-shaped between the shell of burner and the first cavity inner wall, and by sky
The air outlet of flow channel is arranged on the bottom of burner, and during real work, the air of blower fan suction enters burner through air inlet
Portion fills, and flows to the air flow channel of housing both sides, because the air outlet size of air flow channel is smaller.Larger air capacity and smaller
Air outlet so that the wind speed of air outlet is larger, and Reynolds number is smaller, and wind speed is highly stable with air quantity.Air outlet is higher simultaneously
Wind speed larger negative pressure can be produced near air outlet because Coanda effect, substantial amounts of Air Entrainment around is entered into burning
Device portion fills, and increases intake.

Embodiment
Essence of the present utility model is more fully understood for convenience of those skilled in the art, it is new to this practicality below in conjunction with the accompanying drawings
The embodiment of type is described in detail.
As shown in Figure 2 and Figure 3, a kind of blower fan and the combustor portion of burner one fill, including：Housing 1, burner 2 and wind
Machine 3, the housing 1 include the interconnected cavity of left and right two, and the upper and lower sides of left chamber body are all hatch frame, the burner
2 are arranged in left chamber body, and the air flow channel 4 that section is in J-shaped, air stream are formed between the shell of burner 2 and left cavity inner wall
The air outlet 7 in road 4 is located at the bottom of burner 2；The blower fan 3 is arranged in right chamber body, impeller 5 is provided with blower fan 3, on the right side
Cavity is provided with air inlet 6.
Wherein, the air flow channel 4 is distributed in the front and rear side of burner 2, and the slit width of the air outlet of air flow channel 4 is 1mm.Institute
State the side rear that air inlet 6 is arranged on impeller 5.
During real work, the air that blower fan 5 sucks enters combustor portion dress through air inlet 6, and flows to the sky of the both sides of housing 1
Flow channel 4, because the size of air outlet 7 of air flow channel 4 only has 1mm or so.Larger air capacity and less air outlet
7 so that the wind speed of air outlet 7 is larger, and Reynolds number is smaller, and wind speed is highly stable with air quantity.The higher wind speed of air outlet 7 simultaneously
Larger negative pressure can be produced near air outlet 7, substantial amounts of Air Entrainment around is entered into combustor portion because Coanda effect
Dress, increase intake.
A kind of combustor portion dress that the present embodiment provides, blower fan shares a housing with burner, by blower fan and burner
It is integrated, has simplified the internal structure of forced exhaust formula gas heater, it is developed to compact direction, significantly reduce
Cost.Meanwhile the air flow channel design of forced exhaust formula gas heater is more reasonable, wind direction is uniform with wind speed.
Although the utility model in essence is described in detail above embodiment, can not be come with this pair
The scope of protection of the utility model is limited.It should be evident that under the enlightenment of the utility model in essence, the art is general
Logical technical staff can also carry out many improvement and modification, and air inlet is such as arranged on to the side or rear of motor and impeller；Compare again
Air flow channel is such as arranged in the surrounding of burner；Again than said burner portion dress is applied into hot water fields such as wall-hung boiler etc.
Deng.It should be noted that these are improved and modification all falls within claims of the present utility model.On in addition,
"left", "right" in embodiment, " on ", " under ", the restriction of "front", "rear" are stated, is intended merely to that description is convenient and the relative limit done
It is fixed, it is impossible to which that the specific locus installed when applying is filled to limit combustor portion with this.
