Specific embodiment
Presently in connection with drawings and examples, the present invention is described in further detail, these attached drawings are simplified signal
Figure, the basic structure of the invention will be illustrated schematically only, therefore it only shows the composition relevant to the invention.
Embodiment 1
As illustrated in fig. 1 and 2, a kind of kitchen range that the thermal efficiency is high, including enclosing 1, distributor 2 and mixing tube 3.The setting of enclosing 1 is mixed
Close 3 gas outlet of pipe, 32 top；Distributor 2 is arranged in enclosing 1, and the second gas port of several perforation distributor 2 is arranged in distributor 2
21；On the inside of enclosing 1, igniter 4 is set above fire dish 3；1 periphery setting overflow gathering apparatus 5 of enclosing, boils and overflows
Food or other substances, overflow gathering apparatus 5 can be flowed into, prevent the pollution to kitchen range and kitchen.
3 radial section of mixing tube is circle, be arranged gas outlet 32 and two air inlet 31(mono- connect with fuel gas conduit,
One connect with air hose)；It is arranged inside mixing tube 3 several in the unequal semicircle of 3 axial direction spacing distance of mixing tube
The baffle 35 of shape, circular arc position and 3 inner surface of mixing tube of baffle 35 fit；The arrangement of baffle 35 has periodically, baffle
35 3 radial section of mixing tube projection, planar turning over 90 °, that adjacent next baffle 35 can be obtained is radial in mixing tube 3
The projection in section.I.e. semicircular baffle 35 is to be rotated by 90 ° simultaneously edge by its center of circle and perpendicular to the virtual axle in semicircle face
The mobile a distance of the axial direction of mixing tube 3 obtains the position of next block baffle 35.The setting can make air and combustion gas
It is whole to be moved in a manner of non-directional from 3 air inlet 31 of mixing tube to 32 direction of gas outlet；Air and the direction of motion of combustion gas are not
It is disconnected to change, increase the collision between air and combustion gas, is conducive to be more fully mixed combustion gas and air；Air and combustion gas simultaneously
The direction of motion constantly changes eddy flow easy to form, and the mixability for improving combustion gas and air has positive influence.Especially phase
Adjacent two block baffles 35 are different in 3 axial direction spacing distance of mixing tube, compared to being placed equidistant with baffle 35, air and combustion gas
Molecule motion profile variation it is more irregular, the contact probability between air and combustion gas is higher, be more advantageous to improve combustion gas and
The mixability of air is also more conducive to generating turbulent flow or eddy flow, can be further improved the abundant of air and combustion gas mixing
Degree, the design of mixing tube 3 make being more fully mixed for air and combustion gas, to keep burning more abundant, improve the thermal efficiency,
Also reach energy-saving and environment-friendly purpose.35 settable 4 pieces of baffle (just what a is arranged the period), can also according to circumstances change baffle 35
Quantity.
Mixing tube 3 can also be designed to that thickness is inconsistent or distorted shape simultaneously, can make the molecule of air and combustion gas
The direction of motion changes more frequent, is also easier to form eddy flow, has side for the promotion of the mixing sufficient degree of air and combustion gas
It helps.Settable through-hole (not shown) passes through partial air and combustion gas from through-hole on baffle 35；Due to the extruding of through-hole, air
It can become larger with movement velocity when the outflow of fuel gas hole through-hole；The gas for being conducive to attract periphery according to bernoulli principle, promotes sky
The mixing of gas and combustion gas further improves the mixability of air and combustion gas.Baffle 35 can also be designed to spiral plate knot
Structure, is conducive to air and combustion gas generates the raising that eddy flow promotes the two degree of mixing.
Separator disc 33 is set at the outlet of mixing tube 3 32；Be arranged on separator disc 33 it is several axially inclined with separator disc 33, and
Penetrate through the first gas port 34 of separator disc 33.When air and combustion gas pass through the first gas port 34, due to squeezing for the first gas port 34
Pressure, when air and fuel gas hole are flowed out from the first gas port 34, movement velocity can become larger；And according to the pressure of bernoulli principle gas
Power can become smaller, to be conducive to attract the gas on periphery, it is also possible to and eddy flow is formed, mixes air and combustion gas again,
Further improve the mixability of air and combustion gas；The first gas port 34 is obliquely installed simultaneously, changes the fortune of air and combustion gas
Dynamic rail mark, for promote air and combustion gas be mutually mixed sufficiently also play the role of it is positive.
In addition being provided with for enclosing 1 is conducive to shrink flame, so that flame is more concentrated, improves flame and pot
Time of contact reduces heat and distributes into air, and thermal insulation layer 11 is arranged on the inside of enclosing 1 more reduces scattering and disappearing for heat.
Therefore the setting of enclosing 1 can more fully utilize heat, improve the thermal efficiency, save the energy, save combustion gas.
Embodiment 2
As shown in Figures 3 and 4, a kind of kitchen range that the thermal efficiency is high and the structure of embodiment 1 are substantially similar, and difference is: baffle 35
Be designed to the matched circle of 3 internal diameter of mixing tube, and by the spacing distance of 3 axial direction of mixing tube not etc. in a manner of be arranged in
In mixing tube 3.Several through-holes 351 are set on baffle 35, and the through-hole 351 of adjacent screen 35 is arranged difference.
Due to the extruding of through-hole 351, speed can become faster when through-hole 351 is flowed through in air and combustion gas；According to bernoulli principle speed
Degree is bigger, and pressure is smaller；Therefore the pressure of gas can become smaller, the imbalance caused stress, thus be conducive to attract the gas on periphery,
It is also possible to forming eddy flow, is conducive to air and combustion gas mixing is abundant.
Simultaneously because air and combustion gas need just travel forward by through-hole 351, and 351 row of through-hole of adjacent screen 35
Both cloth is also different, therefore the direction of motion of gas constantly changes, and further promotes being mutually mixed for air and combustion gas, improve
Mixing uniformity improve the thermal efficiency to keep air and fuel gas buring more abundant.The size of through-hole 351 can also be with
It is arranged to different more unordered to make air and the motion state of combustion gas change, is more advantageous to and increases air and combustion gas
Collision probability keeps air and combustion gas mixing abundant.
Based on the above description of the preferred embodiments of the present invention, through the above description, related personnel completely can be with
Without departing from the scope of the technological thought of the present invention', various changes and amendments are carried out.The technical scope of this invention
It is not limited to the contents of the specification, it is necessary to determine the technical scope according to the scope of the claims.
