Abstract
A burner for household gas stove features that its head has an eccentric circle to form a symmetrical gap from small to large. When the gas comes from mixing tube to burner head, it passes through the gap to the root of fire holes, resulting in consistent pressure of mixed gas and consistent flame height. Its advantages are less energy loss in gas flowing, fully mixing and high burning effect.
Description
The present invention relates to a kind of burner of gas-cooker, particularly relate to the burner that a kind of combustion chamber has off-centre operation.
Whether the flame height of burner head sectional area and whole volume and each fire hole consistent being correlated with, greatly then flame height is consistent easily with whole volume for sectional area, otherwise then be not easy unanimity, but sectional area and whole area are big, then be easy to generate the tempering noise when lighting a fire and putting out a fire and increased metal consumption, also increased manufacturing cost.Relevant head sectional area and volume are to recommend like this " to get usually more than the twice that the head sectional area is the fire hole gross area in the book that " burning and application " Tongji University etc. writes.When head was longer, in order to reduce the head area, convergent shape can be made along airflow direction in the head cross section, and guaranteed more than the twice of sectional area for the later fire hole gross area of this point of any point ".At coal gas application manual " Japanese coal gas association compiles; relevant burning is such recommendation with volume in the book that Li Qiang's continuous heavy rain etc. is translated " for making each fire hole pressure even, head must dwindle gradually along the moving direction of air-flow, and head is any cross section ＂ that should doubly be advisable with the 2-3 of its front end fire hole gross area arbitrarily.In the market furnace end of gas cooker of Chu Shouing and injection mixing tube be one all meet above requirement, can not flow to the kitchen range face going down but embedded kitchen range requires pot at grate to overflow soup, common used burner does not all meet the requirement of embedded kitchen range at present; From the telescopic burner of external introduction, exist the burner area excessive though meet the requirement of embedded kitchen range, fired heat duty with burning time length can change and little, heat is imitated low deficiency.Also have a kind of burner that meets embedded kitchen range requirement, the burner that its Venturi tube mixer-ejector separates with burner, mist enters the center of burner from the injection mixing tube, enters burner or directly enters burner by three or four shunt again.Though burner sectional area and the requirement that meets two books along separate routes, it is uneven to exist gas to mix equally, and thermic load is little, the deficiency that the thermal efficiency is low.
The purpose of this invention is to provide a kind of injection mixing tube and separate with burner, meet embedded gas-cooker instructions for use, combustion flame is even, and thermic load energy greatly is little, the novel burner that the thermal efficiency is high.
Task of the present invention realizes with the following method: a kind of novel household burner for gas stove, and by nozzle, the air-conditioning plate.8 word air doors, the injection mixing tube, elbow, combustion chamber, furnace shell, the fire lid, the ornamenting circle, spray point, thermocouple probe and location-plate are formed.Its ornamenting circle Gai Zaihuo covers, fire covers the fire tank that inside and outside fire hole is communicated, the inclined-plane of fire lid dependence fire hole and the inclined-plane of furnace shell are to the center, the alignment pin that relies on fire to cover links to each other with location, combustion chamber hole, furnace shell is riveted mutually with combustion chamber, the combustion chamber small end be with furnace shell in the garden of garden heart deviation certain distance in garden, keeping off the air inlet of burner.Eccentric garden and furnace shell interior round-formed by little gradually to big symmetrical slit, 0.5～1.5 millimeter of its width, Cui width is 1 millimeter, the slit gross area is 1.5～1.99 times of fire hole areas, Cui is 1.8 times.Inclined-plane and combustion chamber upper and lower surface by furnace shell form a gas hybrid chamber, make the mist with certain dynamic pressure that enters into burner from the injection mixing tube through after mixing, and enter the gas dynamic pressure power behind the burner from the slit, and static pressure reaches unanimity.Though this does not meet the numerical value that two books are recommended, pressure basically identical during the root of gas arrival fire hole, the burned flame height is consistent.Because drag losses is very little in whole gas flow process, so the effect of induction tunnel injection air is fine, makes primary air fully burn.
The present invention is owing to the gas feed that exports to burner from the injection mixing tube is connected with elbow, and the import of elbow gas and outlet directly through than being 1-5, therefore the damage of dynamic pressure is minimum, have than higher dynamic pressure and fully mix thereby mist arrives burner, overcome the resistance in slit in order to gas.
The present invention is owing to the bottom surface at combustion chamber has three fixed high cylinders, make burner and kitchen range face form the gap, again because combustion chamber has endoporus, make air can enter the endoporus of combustion chamber from the bottom surface of kitchen range face and burner, thereby arrive by the interior fire hole of fire lid, enough required auxiliary airs of burning are provided, guarantee fully burning.
The present invention is inserted in the gas outlet of elbow and close-fitting by the combustion chamber inlet tube, burner is located burner and mixing tube by three fixed high loop pillars of combustion chamber bottom surface with the kitchen range face.Elbow is connected with a screw, and it is reliable and stable to make burner install, and makes pot overflow soup stream on the kitchen range face again.
Below in conjunction with accompanying drawing and an example the utility model is further taken out and to be stated:
Fig. 1 is a cross-sectional schematic of the present invention
Fig. 2 takes fire lid, the burner schematic top plan view behind the case ring away for the present invention
By Fig. 1 Fig. 2 as can be known, the utility model household gas range novel burner is by nozzle (1), air-conditioning plate (2), 8 word air doors (3), injection mixing tube (4), elbow (7), combustion chamber (5), furnace shell (6), fire lid (8), ornamenting circle (9), the spray point thermocouple probe is installed location-plate (10) spray point (11), compositions such as thermocouple probe.Its injection mixing tube, 8 word air doors, elbow is assembled with aluminium die casting die casting and later stage metalworking.Combustion chamber is that aluminium matter furnace shell is copper, and the big external diameter of furnace shell links to each other with combustion chamber with the method for riveted joint, and obviously also available hot investment casting is integral with the later stage metalworking and forms, and also available sheet stamping becomes to rivet behind several parts and forms.
Combustion gas is under certain pressure, flow out from nozzle with certain flow rate, enter into Venturi tube injection mixing tube, combustion gas sucks primary air by the kinetic energy of itself, mixing tube in the injection mixing tube, further mix through elbow mist collision tube wall, the part dynamic pressure can be converted into static energy, mist enters one little mist enters the eccentric garden of combustion chamber through the slit upper chamber behind the burner, most of mist divides two strands to progress into the bottom furnace chamber that enters the eccentric garden of combustion chamber, and along with the slit increases gradually, mist progresses into the upper chamber in the eccentric garden of combustion chamber, owing to the mist dynamic pressure can reduce along with progress path increases, be converted into static energy.Therefore behind the slit that mist process width does not wait, arrive the upper chamber in eccentric garden, its pressure reaches unanimity, and flows out through fire hole then and burns.Smaller in whole gas flow process energy loss, it is also abundant to mix fully therefore burning.When mist arrived the root of fire hole, static pressure ratio was higher, also has certain dynamic pressure, so wind resistance, anti-tempered performance is all relatively good, and flame-out noise is little.
Principle according to the present invention is made several burners and is all obtained desirable effect.Below listed data be to adopt the method for testing of standard GB 16410-1996 resulting.
