Abstract

The utility model provides a light rotational flow burner for household gas range, which is mainly characterized in that a circle of convex edge with the angle of about 45 DEG is arranged on a fire cover, a bar-shaped fire hole is arranged on the lower part of one side of the convex edge which is arranged in radial direction, and the fire cover is stamped into the integration the lower part and a jet exhauster. When the burner is in use, the air flow can move along the inclined plane of the convex edge toward the tangential direction of the fire cover because of the wall-attachment effect of the jet stream, so the rotational flow flame is formed above the burner. The utility model has the advantages of little heat suction, high combustion intensity, and little cold wall effect.

Description

Light rotational flow burner for household gas range

The utility model relates to the light-duty turbulent burner of a kind of house coal gas kitchen.Be suitable for and the supporting use of house coal gas kitchen that wins the trades mark such as many, tame pleasure, lotus.

A kind of household fuel gas stove combustor of patented product (patent No. 90215132.0) by comrade's Sun Wanzhang development, the combustion technology advanced person who adopts, performance is higher, but structure member is more, processing technology is complicated, finds that in use for some time burner fire lid is the fire hole easy deformation particularly, the burner performance is reduced, influence service life.This burner has the inside and outside fire hole former that separates with dividing plate between inside and outside fire lid, the mating surface field of inside and outside fire lid and dividing plate is the inclined-plane, fire hole on the inside and outside fire hole former inwardly tilts along warp-wise, adopt thin corrosion resistant plate manufacturing, owing to inside and outside fiery lid, dividing plate, fire hole former have only four rivets to be connected and fixed, through at high temperature working for a long time, often make the fire hole distortion, cause the fire hole airflow direction to change, influence swirl flow combustion, thereby the burner performance is reduced.

The purpose of this utility model is to overcome the deficiency of above-mentioned technology, utilizes the jet wall attachment effect, has designed a kind of novel energy-conserving house coal gas kitchen turbulent burner.

The purpose of this utility model is such realization: the fire of making at thin corrosion resistant plate covers to be gone out a circle and is fin about 45 °, open a bar shaped fire hole (6) at fin one side-lower, the position of each fin (5) bar shaped fire hole is all identical, fin is radially deployed, when the fire hole of burner is worked simultaneously, just above burner, formed swirl flame.Fin number, length, highly, the fire hole data are determined that by the technical indicators such as load of burner the bottom integral body of fire lid and injector top and chassis and injector strikes out one.

The embodiment of utility model below will be described in detail in detail in conjunction with the accompanying drawings, compare with former patented product, processing technology is simpler, and performance is identical and reliable and stable, and parts significantly reduce, and cost reduces about 10%.Compare with conventional burners, the thermal efficiency improves about 8%, if consume natural gas 1 mark cubic meter every day by each household, but every day solar term 0.08 mark cubic meter, less than 1 year cost with regard to recoverable increase.

The Figure of description explanation: Fig. 1 is a kind of concrete assembling schematic diagram of the utility model.Fig. 2 is Fig. 1 vertical view.Fig. 3 is Fig. 2 I-I cutaway view.-1 injector; The 2-head; The 3-injector first half; 4-fire lid; The 5-fin; The 6-fire hole; The 7-chassis; 8-injector Lower Half.

Embodiment: fuse with reference to Fig. 1, Fig. 2, Fig. 3 burner head and injector, adopt material to be thin Stainless Steel plate.Whole burner divides upper and lower two parts, strikes up partnership through punching press.Burner head is cylindric (2).The centre is hollow, and head is divided into fiery lid and bottom dish (4) (7) again.The fire portion of covering is furnished with circular fin (5), have a bar shaped fire hole (6) on the counterclockwise inclined-plane of each fin, fire hole is positioned at the bottom on fin inclined-plane, and protruding slant edge face angle β is about 45 °, highly is about 5mm, fin is in annulus upper edge radial arrangement, the same two parts up and down that divide of injector, its top (3) fuse with the fire lid, and its underpart (8) fuse with the chassis, adopt stamping technology that two parts punching press about the burner is linked together, just constituted the utility model.The burner of this structure has light weight, and it is little to recept the caloric, and coal gas is after the fire hole ejection, because the wall attachment effect of jet and the steady flame characteristic of fire hole can not taken off fiery phenomenon because of fire hole is shallow.It is mobile along the tangential direction of fire lid that air-flow will paste the inclined-plane, when working simultaneously, the burner fire hole just produces swirling motion (pressing Fig. 2 arrow direction), form stronger tangential force, greatly increased combustion intensity, improved the coefficient of heat transfer, reduce cold-wall effect, in the thermic load scope of broad, can both obtain the very high thermal efficiency.It is a kind of desirable energy-saving coal air burner.

The utility model parts all adopt the 0.5mm thickness not embroider the punch forming of guiding principle plate.For common neat gas burner, fire hole (6) area is 1.5 * 12mm ², sum is more than 24, the parameter designing of injector is selected to keep primary air ratio more than 0.7.

Claims

1, the light-duty turbulent burner of house coal gas kitchen is by fire lid and the injector first half (3) and chassis (7) and injector Lower Half (8) formation.It is characterized in that:

The a fire covers and is furnished with a circle fin (5), has a bar shaped fire hole (6) at fin one side-lower;

B fin and bar shaped fire hole thereof cover radial arrangement along fire;

C fire hole (6) normal and its projection angle β on fire lid horizontal plane are the 30-45 degree, and the projecting direction of fire hole (6) normal on fire lid horizontal plane is the tangential direction of fire lid circumference.

2, the light-duty turbulent burner of house coal gas kitchen according to claim 1, it is characterized in that: the material of each parts is a corrosion resistant plate.
