The specific embodiment

At first with reference to Fig. 1, show and implement gas burner 10 of the present invention, it has the air intake pipe AP that leads to its bottom.Air intake pipe AP comprises air valve AV.Fuel gas inlet pipe FP leads to a side of burner 10, and comprises main burner valve BV.In the upstream of main burner valve BV is apparatus control valve CV, guide valve PV and flame interrupting device FF, and guiding pipeline PL and control pipeline CL extend to burner 10 from flame interrupting device FF.

With reference to Fig. 2 to 5, gas burner 10 comprises cylindrical center gas combustion chamber 11, and center gas combustion chamber 11 is arranged in cylindrical double-walled periphery air chamber 12 inside coaxially fully.Annular gas mixing chamber 13 is limited by centre chamber 11 and peripheral compartment 12 and is therebetween.Mixing chamber 13 has open top 28, and flame is emitted by this open top.

Centre chamber 11 has first cylindrical wall 21, and described cylindrical wall 21 is formed with a plurality of holes 17 of passing it, and described hole 17 is arranged in ring or the circular array that three perpendicular separations are opened.Peripheral compartment 12 comprises second cylindrical wall 20 equally, and described second cylindrical wall 20 has a plurality of holes 16 of passing it.Described hole 16 is arranged in four circular array, and each is around centre chamber 11.

Four circular array in hole 16 arrange with regard to vertical direction regularly.Similarly, three of hole 17 circular array arrange with regard to vertical direction equally spacedly.The array in the array in hole 17 and hole 16 is staggered symmetrically, thereby hole array 16 and hole array 17 are vertically arranged in an alternating manner.More specifically, each hole array 17 vertically is positioned at around the center of its two adjacent holes arrays 16.

Locular wall 20 and 21 is passed with radially non-or spiral way extension, as shown in Figure 3 in hole 16 and 17.

Mixing chamber 13 has diapire 22, is mounted with centre chamber 11 on it.Burning gases inlet 14 passes the center of diapire 22, and bend pipe 23 14 extends to fuel gas inlet port 19 from entering the mouth.Inlet port 19 passes the cylindrical outer wall 24 of gas burner 10, and burning gases inlet tube FP is connected to this inlet port 19.

Peripheral compartment 12 has the following isolated diapire 25 with the diapire 22 of mixing chamber 13.This provides the space that is used for bend pipe 23 at interval.Diapire 25 has center air inlet port 18, and air intake pipe AP is connected to this inlet port 18.26 times pyrophoric flame 27 is set at cover, it receives the fuel gas from guiding pipeline PL.Control pipeline CL is connected to the thermocouple 15 on pyrophoric flame 27 next doors and detects so that carry out flame.

Fig. 6 shows the commercial stove that comprises gas burner 10.Described stove comprises the recess that is centered on by outstanding loop configuration 9, is used as the particularly support member of pot of cooking container, and gas burner 10 is installed in this recess and is positioned at the bottom of recess.Relevant gas and air supply pipe road etc. are arranged in the body of heater.

In operation, fuel gas is transported to fuel gas inlet port 19 under pressure, enters centre chamber 11 via bend pipe 23.Fuel gas enters mixing chamber 13 by hole 17 along the direction of arrow A shown in Figure 3 subsequently.Simultaneously, air is supplied to (for example passing through electric fan) under pressure to air inlet port 18, and through around the bend pipe 23 and peripheral compartment 12.Air enters mixing chamber 13 along the direction of arrow B by hole 16 then.Two kinds of air current A and B introduce the counterclockwise eddy current of gaseous mixture (fuel gas and air) in mixing chamber 13.

Gaseous mixture will be lighted to be used for burning, by the open top 28 generation flame eddy current of mixing chamber 13 by pyrophoric flame 27.The size of flame can be regulated by rotation main burner valve BV and air valve AV, and described main burner valve BV and air valve AV are mechanically coupled together so that operate simultaneously to keep the gas/air mixing ratio.

Staggered in locular wall 20 and 21 of hole 16 and 17 ring or alternately arrange and between fuel gas and air, to produce near smoothly layer mixing in the multilayer mode.Like this, even the also burning of peace and quiet or low noise (84dBA) relatively under the situation of the complete flame that the minimizing owing to turbulent flow causes.The gas deep structure of the mixing chamber 13 of mixing and burning therein also helps to improve the noise control performance.

Fast and/or more fully gas mixes and can be guaranteed, thereby causes the more effective utilization and the thoroughly burning of fuel gas greatly, and these have brought the remarkable improvement of firing rate and combustibility together.

The present invention only provides in the mode of example, and under the situation of the scope of the present invention that does not depart from claims defined, those skilled in the art can carry out various modifications and/or distortion to these embodiment.For example, fuel gas and air inlet port can exchange, thereby fuel gas is transported in the mixing chamber via the peripheral compartment.
