The unreasonable structure of traditional burner stove combustor, combustion gas burn-off rate is low, wastes energy, contaminated environment.The combustion system of tradition cooking stove " rear mixing burning " has continued for many years, and National Technical superintendent office formulated kitchen range professional standard in 1999, and the thermal efficiency of its standard is only 20%, and waste reaches 80%.Based on the generality of this kind of present situation, in industry, many companies or individual also successively improved traditional cooking range structure in recent years.Improvement project is " premix combustion ", before burner combustion zone, namely arrange a pre-confounding, makes combustion gas before combustion first in the air mixing that pre-confounding and air blast are sent here, then under the effect of blast and air pressure, combustion zone is delivered in air mixture and lights.This kind improves the efficiency of combustion that improve combustion gas to a certain extent, reaches certain energy-saving effect.But all a series of common faults of premixed kitchen range ubiquity put goods on the market so far, main manifestations is: although achieve premixed combustion, and gas and vapor permeation cell structure common design is simple, and technique is simple and crude; Combustion gas and air enter without fully mixing after mixing chamber, and moment is just admitted to combustion zone and lights, and its combustion efficiency is well imagined.Due to above reason develop a kind of reasonable in design, energy-saving gas stove that combustion gas utilization rate is high becomes industry problem demanding prompt solution.
Summary of the invention
The utility model in order to solve current gas furnace gases mixing chamber structure simple, fuel gas and the well-mixed problem of air cannot be made, a kind of rational in infrastructure, energy-saving gas cooker gas mixing device that combustion gas utilization rate is high is provided, it comprises: a hollow mixing chamber housing, be located at the gas outlet of mixing chamber housing upper end, be located at least one air inlet of mixing chamber housing bottom and at least one fuel gas air inlet and the vortex generator be arranged in mixing chamber housing.Premix chamber is formed between the outer wall of described vortex generator and mixing chamber inner walls, after described air and fuel gas tentatively mix in premix chamber respectively by air inlet and fuel gas air inlet, again mix through vortex generator, exported by the gas outlet of mixing chamber housing upper end.
Described vortex generator surrounding is provided with at least two circle non-static fields water conservancy diversion inclined holes; Upper end is provided with opening, and is provided with the vortex generator flange sealing with inner walls and fix in vortex generator upper end.Described mixing chamber Housing Base has at least one air inlet and at least one fuel gas air inlet.
The airflow-resistive plate that one has circular lower concave curved surface is also provided with in mixing chamber.Its concave curvature side is positioned at vortex generator open upper end, and distance vortex generator opening has one section to be about the distance of 20 to 25 millimeters.When mist sprays from vortex generator upper end, airflow-resistive plate can make it rolling and mixes further by longitudinal barrier air.
Cylindrical mixing chamber casing center is provided with fixed bar, and vortex generator is arranged on the lower end of mixing indoor fixing rod, and airflow-resistive plate is arranged on fixed bar upper end.
Vortex generator and mixing chamber inner walls to be sealed by draw-in groove that mixing chamber inner walls is arranged and fixingly form premix chamber by vortex generator flange.Air and fuel gas enter behind premix chamber from the air admission hole mixing chamber Housing Base, the hybrid chamber being entered vortex generator inside by the non-static fields water conservancy diversion inclined hole on vortex generator forms eddy current realization rotation mixing, because air and fuel gas constantly enter hybrid chamber from non-static fields water conservancy diversion inclined hole, so the gaseous mixture in hybrid chamber knows from experience the below being sprayed onto airflow-resistive plate concave curvature from the opening upwards of vortex generator upper end.The gas sprayed in hybrid chamber mixes again because the barrier effect being subject to airflow-resistive plate rolls in airflow-resistive plate concave face, and secondary mixes complete gas and enters diversion cavity from the outflow of airflow-resistive panel edges, finally enters combustion zone.
The stove core mixing chamber degree of depth of the existing cooking stove in market is generally between 20 to 30 millimeters, the utility model is deepened mixing chamber between 100 millimeters to 150 millimeters, especially with 125 millimeters of mixed effect the bests, deepen the mixing chamber degree of depth and make air and fuel gas have enough spaces to mix.In addition, devise vortex generator gentle flow resistance baffle plate two-stage in mixing chamber of the present utility model and mix gas system, first mist enters in the hybrid chamber of vortex generator from non-static fields water conservancy diversion inclined hole, carry out first time eddy current rotation mixing, mist sprays from vortex generator upper end open subsequently, because the barrier effect being subject to airflow-resistive plate makes mist further tumble mixed below barrier plate concave face, this makes fuel gas fully mix with air, significantly improves the combustion gas utilization rate of fuel gas.
