Abstract

The utility model discloses a leakage-proof inflamer. The inflamer is composed of a furnace head, a distributor arranged on the furnace head, and an outer ring inflamer arranged on the distributor, wherein, the center of the distributor is provided with a through hole; the through hole is provided with an internal ring flamer connected with a central tube of the furnace head; a dirt-proof ring is arranged around the inner ring inflamer; a protruding table is arranged around the through hole at the distributor center; and the radial of the dir-proof ring on the inflamer covers the through hole. The soup and dirt will not drop in the kitchen range bottom shell or the furnace head chamber, which is convenient to clean. Besides, the inflamer is designed into a dual-chamber structure of a distributor chamber and a furnace head chamber, the connection structure between a nozzle and a guide ejection tube and the shape of a fire groove is changed, thus the inflamer is unlikely to backfire with a good air guide ejection at one time, and the CO content is reduced with the flame concentrated at the center of the pan bottom during burning, which reduces the outward radiant heat and increases the heat efficiency by 60%-67%.

Description

The burner of anti-leakage

Technical field:

The utility model relates to a kind of burner that is applied to gas kitchen ranges, refers in particular to a kind of burner of anti-leakage.

Background technology:

Existing application has varied in the burner of gas kitchen ranges, a kind of burner that has inboard fire hole is wherein arranged, the flare of each fire hole of this kind inner flame combustor is concentrated to center spray combustion and is accumulated flame upwards, so this kind inner flame combustor has the thermal efficiency higher than traditional outer flame burner.However, this type of burner still exists following defective and deficiency:

1, existing internal flame formula combusting device stove burner is because the relation of performance, the burner that similar table type kitchen range before all adopting uses, there is individual macropore the centre, auxiliary air is come in from middle macropore, use is on built-in type cooker, cause soup and dirt to fall into the kitchen range drain pan from the burner interstitial hole, user's cleaning is difficulty very.

2, the nozzle mounting means of existing internal flame formula burner is that nozzle is adorned askew easily at installing hole of burner body induction tunnel primary air porch processing, influences primary air and introduces, and causes that easily tempering and CO content increase.

3, existing internal flame formula burner is because the relation of the structure and the thermal efficiency, it is following or flush with panel to be installed in the kitchen range panel, and the temperature of kitchen range the inside and burner body is very high during use, causes the reduction of primary air mass ratio of induced-to-inducing air, tempering easily, kitchen range reduce service life.Simultaneously, burn required primary air and auxiliary air along with increase burning time, just can cause the replenish air deficiency all from the kitchen range the inside, cause imperfect combustion, and CO content in smoke increases, and influences user's safety.

The utility model content:

Technical problem to be solved in the utility model provides a kind of burner with high efficiency of preventing leakage.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of burner of anti-leakage, comprise burner, be installed in distributor on the burner, be installed in the outer shroud burner on the distributor, the center of distributor is provided with through hole, be provided with the interior ring burner that is connected with the central tube of burner in the through hole, it is characterized in that: the periphery of ring burner is provided with antifouling ring in described, the periphery of distributor central through hole is provided with boss, and antifouling ring radially covers this through hole burner.

The periphery of described distributor is provided with the eaves limit of radially extending, and described eaves limit is positioned at the top of kitchen range panel.

As further improvement of the utility model, form the distributor chamber between described distributor and the outer shroud burner, form the burner chamber between distributor and the burner; Be provided with the air flue that is connected of some connection distributor and outer shroud burner in the distributor chamber.This outer shroud burner comprises outer fire cover and the outer fire cover seat chimeric with outer fire cover, the outer fire cover seat be installed on the distributor or with the distributor one, outer fire cover is provided with some clearance types fire grooves.Clearance type fire groove circumference is evenly distributed on the outer fire cover inboard with the chimeric place of distributor, is provided with two long fiery grooves between the adjacent two short fiery grooves.

Clearance type fire groove tilts to the longitudinal center line top, and the angle of groove and groove projection on horizontal plane is 3～10 °.

The upper surface of ring burner is than the low 5～10mm in outer shroud burner upper surface in described.Should comprise inner fire cover and the inner fire cover seat chimeric with inner fire cover by interior ring burner, the inner fire cover seat is installed on the central tube of burner, and antifouling ring is arranged on the inner fire cover, and the inner fire cover upper surface is provided with 3 to 6 boss that have clearance type fire groove.

Further improve as of the present utility model, be provided with the jockey that makes the coaxial slip of nozzle between the injector on the described burner and the nozzle.The jockey of described coaxial slip comprises the nozzle carrier of fixedlying connected with nozzle, and the nozzle carrier front end is connected with the installing ring that can be sleeved on the injector, and installing ring is connected with injector by the screw that radially is provided with.

The utility model compared with prior art has the following advantages:

First: because a flanged circular hole is arranged in the middle of the distributor of the utility model burner, and there is the inner fire cover antifouling ring of difference in height to block, again because of distributor is provided with the eaves limit above panel, so soup, dirt can not fall kitchen range drain pan and the inside, burner chamber, and convenient for cleaning.

Second: because burner described in the utility model has two cavitys, burner is installed in below the panel and the distributor above the panel has certain distance, so more present low of burner cavity temperature.Make burner be not easy tempering, the primary air injection is good and then reduce CO content, improves the thermal efficiency.

The the 3rd: because burner described in the utility model has two cavitys, distributor is installed in above the panel, and there is certain distance can advance auxiliary air between distributor and the outer fire cover, burn required auxiliary air from the kitchen range outside, can not burn required auxiliary air from the kitchen range the inside as existing inner flame combustor, avoid along with increasing lack of air burning time, cause CO content to increase, yellow flame occurs.

The 4th: because the outer fire cover of burner described in the utility model fire groove is a clearance type, and is inclined upwardly, flame is concentrated to centre, the bottom of a pan when making burning, has reduced to extraradial heat, and then has improved the thermal efficiency.

The the 5th: because burner nozzle seat described in the utility model can slidable adjustment relative distance on injector together with nozzle, be transferred to behind the optimum distance with screw fixed nozzle seat, therefore consistent in the time of can guaranteeing combustion conditions with design, and the stability during the assurance burner operation.

The the 6th: because the nozzle of burner described in the utility model is connected with injector is coaxial, therefore can guarantee that nozzle and injector are concentric, and then improve the primary air ejector capacity, reduce CO content, improve the thermal efficiency.
