Description
Technical field
The invention belongs to gas kitchen ranges technical field, relate to a kind of kitchen range burner, especially
It relates to a kind of burner for gas kitchen range structure.
Background technology
Civil kitchen range all uses atmospheric burning type method, this is because this kind of burner, in advance
Having mixed partial air so that combustion flame is short, firepower is strong, and temperature is high, efficiency of combustion ratio
Diffusion type combustion system wants high, combustion gas of different nature of can also burning, combustion completion,
Can be applicable to low-pressure fuel gas, and need not other power-equipment, so burning than other
Method is more suitable for domestic gas appliance.But the atmospheric burner of tradition kitchen range is due to domestic
Source of the gas is complicated, and processing technique falls behind, less demanding to cooking apparatus of people, if energy
Burn just, think little of not pursuing accurate and excellent combustion conditions, manufacture producer
Technical capability the lowest, a lot of products all do not reach existing national standard.
The burner of traditional gas kitchen ranges is designed with interior burning circle and outer burning circle, thus
Form circle endogenous fire and an outer fire when burning, existing burner structure is typically provided with and draws
Emitter carries out primary air mixing, namely a corresponding injector of burner, by
It is difficult to control primary air amount in an injector, causes surplus air too much when burning
Take away too many heat, thus cause the thermal efficiency low.Also there are two injectors of employing,
And an injector connects the outer circle that burns, another injector connects inner burner, respectively
Supply, respectively air inflow of regulation, but this design needs when flame regulates respectively
Regulation endogenous fire and outer fire, use inconvenience, and thermic load be the highest.
In order to overcome the deficiencies in the prior art, there has been proposed various solution,
As Chinese patent literature disclose a kind of gas kitchen ranges burner [application number:

Lower section is provided with case, and this case covers the lower end of described burner body, this case interior
Chamber and aforementioned auxiliary air venthole configured in fluid communication, and the side of aforementioned case is provided with energy
Blower fan by extraneous air introduced cover intracoelomic cavity.
All draw from case due to primary air and auxiliary air, and the sky in case
Gas is again that blower fan strength sucks in, and therefore fuel gas buring is very abundant, in burner combustion
During by conduction of heat and heat radiation, heat the air in airtight case, burning is more filled
Divide thus improve the efficiency of combustion of combustion gas further；During due to burning, air fills into and quite fills
Foot, and air is all to enter below burner body, the therefore benefit to air above
Enter the most too high request, can effectively reduce the height of cooker racks, it is simple to cleaning, embedding can be made
The development prospect of formula gas-cooker is more wide.
But the structure of such scheme is complex, and not to injector and burner
The connection of body is made improvement thus is improved efficiency of combustion.
