Utility model content
An object of the present utility model is to solve at least the problems referred to above and/or defect, and after providing at leastBy the advantage of explanation.
The utility model also has an object to be to provide a kind of energy-saving burner with gas mixing unit, itsCombustion gas and middle pressure air fully can be mixed, so that its later stage sufficient combustion, energy-conserving and environment-protective.
In order to realize according to these objects of the present utility model and other advantage, provide one to there is combustion gasThe energy-saving burner of mixing arrangement, comprises housing, and is arranged on combustion chamber and the inlet air plenum of enclosure interior,Also comprise:
For combustion gas and air are carried out to well-mixed at least two group fan blades, described in it is successively set onOn the flow path forming in inlet air plenum.
Preferably, wherein, respectively organize diameter mode to increase progressively successively on flow path of described fan bladeArrange.
Preferably, wherein, on the sidewall of described combustion chamber, be provided with for mixed combustion gas and enter combustionBurn indoor nozzle.
Preferably, wherein, the bottom side of described inlet air plenum is provided with fuel gas inlet, and described combustion gasImport is positioned at the below of bottommost fan blade.
Preferably, wherein, one end diameter that described inlet air plenum is positioned at air inlet is less than the other end, and itsTwo ends are by step-like changeover portion and then a connection.
Preferably, wherein, one end that described changeover portion and inlet air plenum diameter are larger is entered by a contraction flow regionAnd transition connects.
The utility model at least comprises following beneficial effect: one, and in its inlet air plenum in burnerBe provided with at least two group fan blades, it is for the combustion gas entering in combustion chamber is fully mixed with air,So that it mixes, can burn fully, save combustion gas, reduced the air dirt in kitchen simultaneouslyDye.
Its two, because the diameter of two groups of fan blades arranges in the mode increasing progressively in inlet air plenum, inlet air plenumThe diameter proportioning being mated, makes its wind have the effect of speed governing, mixed combustion on wind direction flowingMore smooth and easy when gas enters combustion chamber, more favourable.
Other advantage of the present utility model, target and feature embody part by explanation below, partAlso will be by research and practice of the present utility model be understood by those skilled in the art.
Brief description of the drawings
Fig. 1 is the structural representation of traditional energy-saving burner;
Fig. 2 is the knot in another embodiment of the present utility model with the energy-saving burner of gas mixing unitStructure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, to make those skilled in the artCan implement according to this with reference to description word.
Should be appreciated that use herein such as " having ", " comprising " and " comprising " term alsoDo not allot existence or the interpolation of one or more other elements or its combination.
Fig. 2 shows according to a kind of energy-saving burner with gas mixing unit of the present utility model, comprisesHousing 2, and be arranged on combustion chamber 20 and the inlet air plenum 21 of enclosure interior, also comprise:
For combustion gas and air are carried out to well-mixed at least two group fan blades 22, it is successively set on instituteState on the flow path forming in inlet air plenum, it is for carrying out pressure air and combustion gas by two groups of fan bladesBe uniformly mixed, and the operation principle of two-stage fan blade is the net that enters the middle pressure wind of inlet air plenum by blower fanThe moving autorotation of speed belt stirs, and does not need external connection power just to realize air and combustion gas mixing, for the later stageFully burning provides preparation, has also prevented that unburned combustion gas from overflowing environmental pollution and the energy waste causing.Adopt this scheme to there is the favourable part of energy-conserving and environment-protective. And this mode is a kind of preferred embodimentsExplanation, but be not limited to this.
In another kind of example, respectively organize diameter mode to increase progressively successively on flow path of described fan bladeArrange. Adopt the mode that in this scheme, fan blade diameter increases progressively, can play the effect of speed change, make itThe combustion gas mixing can enter into combustion chamber smoothly, has the favourable part that implementation result is good. And, thisMode is a kind of explanation of preferred embodiments, but is not limited to this.
In another kind of example, on the sidewall of described combustion chamber, be provided with for mixed combustion gas and enter combustionBurn indoor nozzle 23. Adopt this scheme to make can pass through nozzle by the combustion gas after fan blade StirringEnter into combustion chamber, there is the favourable part that implementation result is good. And this mode is that one is betterThe explanation of example, but be not limited to this.
In another kind of example, the bottom side of described inlet air plenum is provided with fuel gas inlet 24, and described combustionGas import is positioned at the below of bottommost fan blade. Adopting this scheme to make to enter the combustion gas of inlet air plenum can be suitableProfit down the wind all enters in combustion chamber by the rotation of fan blade, prevents that it from overflowing, and causes environmentImpact, have energy-conservationly, environmental protection, can the good favourable part of implementation result.
