Description
Technical field
The utility model is related to a kind of stove heat shield, the utility model, which further relates to a kind of application, the stove heat shield
Kitchen range.
Background technology
With the development of city gas cause, the kitchen range industry in China kind, material, performance, sales volume etc. have compared with
It is big to improve.It is important that being exactly the raising of the thermal efficiency in its performance boost.The burner of household gas range belongs to air more
Formula burner.Atmospheric burner is the burner designed according to partial pre-mix mode, primary air ratio 0<α<1.Greatly
Gas formula burner is divided into head and injector two parts.Injector is for the primary air needed for injection burning, burner head
Effect be then combustion gas, air mixture to be uniformly distributed on fire hole, and stablize and complete burning.Gas-cooker
Combustion gas is all primary energy mainly by liquefied petroleum gas, natural gas, biogas etc..By taking natural gas as an example, the day in annual China
Right gas usage amount is all rising, and wherein some is exactly to be used for home-use gas.Home-use gas is largely consumed in cooking utensils
On, therefore the thermal efficiency for improving cooking utensils can not only reduce consumption and the greenhouse gas emissions of combustion gas resource, while
The combustion gas expenses of user can be reduced, air quality is improved.Therefore the efficiency for improving gas-cooker is always China's kitchen range row
One of objective of the struggle of industry.Existing gas-cooker in actual use, is taken to set and be heated on pan bracket due to cookware, pot
There is certain space interval between burner, the thermal energy that such fuel gas buring generates is other than being used for heating kettle, also phase
When a part escapes in ambient enviroment, energy waste is caused；It is to solve the above-mentioned problems, domestic in recent years that there have been some collection
Hot polymerization energy, " for the cumulative circle of gas-cooker and gas-cooker with it " as disclosed in Chinese patent CN203404823U, and
" a kind of energy gathering type gas cooker " as disclosed in Chinese patent CN204042984U also has cumulative pan bracket in the kitchen range,
Although above-mentioned such cumulative coil structures, can reduce the consumption of thermal energy, gas-cooker is typically placed to a certain extent
The ventilation in kitchen is likely to result in gas-cooker combustion flame and waves, is unstable, sometimes very when wind-force is larger in external environment
It can extremely cause to stop working, influence to use.In addition, there is also sliding pot, soup overflows of boiling to enter burning for existing general gas stove
The burner of device, fire hole etc., phenomena such as causing gas combustion range flameout, misfire.
Invention content
A technical problem to be solved in the utility model be for the above-mentioned prior art present situation and providing a kind of can have
Effect improves the stove heat shield of combustion gas utilization rate.
Another technical problem to be solved in the utility model is to provide one kind by the above-mentioned heat shield of application both to have had
There is thermal-arrest cumulative action not influence secondary air again to ensure the clean-burning kitchen range of combustion gas.
Technical solution is used by the utility model solves above-mentioned technical problem：The stove heat shield, includes annular
Cover body, it is characterised in that：The cover body is to cover the double-layer structure constituted by upper layer cover and lower layer, it covers in the upper layer cover and lower layer
Between be formed with cavity, the lower layer, which covers at least three on the bottom wall of the corresponding cavity, to be had concaveconvex structure and is formed circumferentially
The stabilizer blade of distribution forms secondary air channel between adjacent leg.
The bore in the secondary air channel is wide outside and narrow inside.The design wide outside and narrow inside both enhances the effect of suction air
Orientation and water conservancy diversion have been carried out to air again, improve the speed of supplement auxiliary air while having also reduced the resistance of gas supply, effectively
Ground carries out filling into for auxiliary air, improves combustion gas utilization rate.
Wherein, wide outside and narrow inside to show in above-below direction, the roof in the secondary air channel from outer circumferential center by
Gradually tilt upwards.On the one hand this design can strengthen the swabbing action to auxiliary air；On the other hand, high outer in secondary air channel
Low gradient design has directional stream-guidance effect to auxiliary air, it is ensured that auxiliary air passes through just face external ring fire cover after heat shield
Fire output hole, reduce the supply resistance of the external ring flame of auxiliary air, so that secondary air supply is obtained rapider.
Preferably, the cavity inside filled with air, heat-barrier material or vacuumizes.Heat-barrier material such as ceramic fibre is one
The good heat-insulating heat-preserving material of kind, this heat-barrier material can play heat build-up chamber good thermal insulation function, prevent the stream of heat
It loses, and air is most economical universal thermal insulation material, and the outside heat transfer of cover body can be reduced using its excellent insulation characteristic.
The upper layer is covered and lower layer's cover is structure as a whole or separate structure.Integral structure is easy to implement to be vacuumized, and seperated
Structure then dismounting easy to implement.
The utility model provides a kind of kitchen range using above-mentioned stove heat shield to solve second technical problem, wraps
Include stove panel and burner, the burner includes mixing chamber and the secondary air that is arranged on the mixing chamber
Mouthful, the heat shield is arranged on stove panel and surrounds the burner, it is characterised in that：The heat shield cover body it is secondary
Air intake passage is aligned setting one by one with the secondary air inlet.
In order to realize good heat build-up effect and meet in ring fire auxiliary air supplement, the heat shield cover body it is interior
The highest point on side edge is less than the main fire hole of outer fire cover but the secondary air inlet being higher than in mixing chamber in the burner.
In order to preferably reflect thermal energy and prevent influence air flowing, the inner side edge edge of the heat shield cover body it is straight
Diameter is more than the outer edge diameter of mixing chamber in burner, and the two difference is 13~21mm, i.e., the inner side edge of the described heat shield cover body
It is 6.5~10.5mm along the radial clearance δ between the outer edge of mixing chamber in burner.
Compared with prior art, the utility model has the advantage of on the basis of existing gas-cooker, add stove with heat-insulated
Cover, which is double-layer structure, and stabilizer blade covers recessed formation by lower layer, on the one hand can increase the body of heat shield internal cavity
Product, while the capacity of air or heat-barrier material in heat shield is also increased, it can also improve heat preservation while saving cost of material
Characteristic；Upper layer cover can also be effectively reduced to the heat output at four stabilizer blades, that is, reduce dissipating from four stabilizer blades to stove panel
Heat；In addition, forming secondary air channel between adjacent leg, the air on the outside of such cover body is flowed into through the secondary air channel to be covered
When the interior area encompassed of body, it can achieve the purpose that effectively to preheat auxiliary air by the bottom of stabilizer blade and lower layer's cover, carry
High combustion gas utilization rate.
