Detailed description of the invention
Understand essence of the present invention better for convenience of those of ordinary skill in the art, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in Figure 1, a kind of gas-cooker with air blast, comprising: burner 1, is connected to the gas distribution box 2 on burner 1, and the nozzle 3 be connected on gas distribution box 2 and air blast 4; Described gas distribution box 2 is used for controlling blast air and fuel gas flow direction, makes blast air and combustion gas after gas distribution box 2, flow out direction consistent.
Shown in composition graphs 2, Fig. 3, described gas distribution box 2 comprises: blast channel 21, blast tube 22, primary air injection passage 23, and blast channel 21 is provided with connector 24 and blast air outlet 25.Described blast tube 22, primary air injection passage 23, all by the up/down perforation of gas distribution box 2, are respectively induction tunnel delivery of fuel gas and primary air.Described connector 24 is connected with air blast 1 by wireway 5, described blast air outlet 25 is looped around the week edge that blast tube 22 exports, not only guarantee that blast air is out rear consistent with fuel gas flow direction from gas distribution box, also improve blast air and fill with combustion gas the uniformity mixed.In other embodiments, if blast air outlet and blast tube are exported consistent towards being arranged to, blast air can be reached from out afterwards consistent with the fuel gas flow direction object of gas distribution box.
In the present embodiment, preferred burner 1 comprises two gas injection pipes 11, described gas distribution box 2 is connected with the air inlet of two gas injection pipes 11, and corresponding each gas injection pipe 11 is provided with blast tube 22, blower air outlet 25 and primary air injection passage 23 on gas distribution box 2.
The each blast tube 22 of preferred correspondence is provided with two primary air injection passages 23, two primary air injection passages 23 are evenly distributed on blast tube 22 both sides, to optimize the combustion conditions (Huang Yan, from flame, tempering) during high flame burning, reduce the unstability of flame during burning.。
Preferred gas divided flow box 2 and burner 1 are integrated casting structure, with the extra installation procedure avoiding gas distribution tape.
Preferred blast air outlet 25 exports the annulus of surrounding for being trapped among blast tube 22, fully mix with combustion gas to make blast air.In other embodiments, described annulus is replaced by annular array hole, is not limited to the present embodiment.
Further, for ensureing the injection volume of primary air, preferably on the air inlet of primary air injection passage 23, being provided with air regulating board, preferred nozzle 3 being also provided with the other hole of nozzle.
During real work, air blast is communicated with the inner chamber 21 of gas distribution box by wireway 5, provides burning blast air.When the actual heating load of gas-cooker lower than rated heat input, rated heat load 40% time, air blast does not start, combustion gas is penetrated from nozzle 3 and is entered burner 1, simultaneously from the other hole of nozzle and air regulating board injection primary air, two strands of primary airs jointly enter burner trunnion place with combustion gas and mix, and ensure the normal combustion of gas-cooker; As shown in Figure 4.When the actual heating load of gas-cooker is not less than 40% of rated heat input, rated heat load, air blast starts, and combustion gas is penetrated from nozzle 3 and entered burner 1, simultaneously from the other hole of nozzle and air regulating board injection air; In addition, the air that air blast blasts enters gas distribution box 2 from wireway 5, by the distribution of gas distribution box 2, bloat from jet-flow surrounding, three strands of air jointly enter burner trunnion place with combustion gas and mix, under the prerequisite ensureing gas-cooker normal combustion, optimize combustion conditions, improve the product thermal efficiency; As shown in Figure 5.Wherein, the concrete startup of air blast can be controlled by signals such as potentiometer, displacement transducer, flow sensor, microswitch, thermocouples opportunity, and the generation of control signal has a lot of conventional design, repeats no more here.
In addition, for ensureing the thermal efficiency, the air capacity that air blast blasts is no more than 50% of total injection air capacity.The applicant is to 4.0kw (A line), 4.2kw (B line), 4.5kw (C line), under 4.8kw (D line) four kinds of thermic load states, blast air amount duty gas total amount percentage and thermal efficiency relation are simulated, as shown in Figure 6.As can be seen from the figure, when blast air amount duty gas total amount percentage lower than 30% time, thermal efficiency of gas stove increases along with the increase of blast air amount duty gas total amount percentage, when blast air amount duty gas total amount percentage higher than 50% time, thermal efficiency of gas stove occur along with the increase of blast air amount duty gas total amount percentage reduce.
Above detailed description of the invention has been described in detail essence of the present invention, but can not limit protection scope of the present invention with this.Apparently, under the enlightenment of essence of the present invention, the art those of ordinary skill also can carry out many improvement and modification, it should be noted that these improve and modify and all drops within claims of the present invention.
