Abstract

The utility model relates to a novel high-effective energy-saving gas-burning range, comprising an outer burning chamber 10 and inner burning chamber 9 arranged in the middle of the outer burning chamber 10. The two burning chambers are respectively communicated with gas-burning injectors 7, 8. A concave ceramic perforated plate 11 is arranged on the burning chambers. A concave infrared radiation metal net 13 is arranged above the surface of the ceramic perforated plate. The utility model has the advantages that heat load can be increased 25% or so due to the structure; heat efficiency which can reach 63% is obviously enhanced; the heat efficiency is enhanced 3.15 times, compared with a national standard GB7824-8. A concave heat radiation flame stabilizing net which is inosculated with a burning head is adopted for increasing a radiation function of 10% or so. The utility model has the advantages of double-stove chamber and three utilization grades of a small fire, a big fire and a full fire. A satisfactory utilization effect can be achieved.

Description

The novel high-efficiency and energy-saving gas-cooker

The utility model relates to gas burner, particularly a kind ofly is fit to do the novel high-efficiency and energy-saving gas-cooker that the dish kitchen range is destroyed in the Chinese meal combustion gas.

Along with constantly popularizing and raising of city gasification, develop energy-efficient fuel gas product, particularly important to user and country, the gas kitchen ranges of domestic production at present is atmospheric burner and plane Flameless burner and single-layer type concave surface burner, its thermal efficiency is all not high, Chinese meal gas cooking stove particularly, the standard GB 7824-87 standard code thermal efficiency＞20%, though the single-layer type concave surface burner thermal efficiency increases, but the stove surface temperature up to 300 ° about, thermal efficiency loss is bigger, and is easy to generate tempering, scald situation.

The purpose of this utility model is to provide a kind of and designs according to the matrix pot, and it is bigger to make the bottom of a pan can make full use of the radiant heat of burner near combustion front especially, obviously improves the thermal efficiency, is particularly suitable as the novel high-efficiency and energy-saving gas-cooker that Chinese meal stove uses.

Above-mentioned purpose of the present utility model, be to realize by such technical scheme: promptly a kind of novel high-efficiency and energy-saving gas-cooker is characterized in that: comprise exterior combustion chamber, inner combustion chamber therebetween is set; Two combustion chambers are communicated with a combustion gas injector respectively; The ceramic porous plate of concave surface is set on the combustion chamber, concave surface infra-red radiation wire netting is set in the surface of ceramic wafer.

Said structure of the present utility model can further specify by the non-limiting embodiment that accompanying drawing provides.

The utility model has following accompanying drawing:

Accompanying drawing 1 is a structure cutaway view of the present utility model;

Accompanying drawing 2 partly cuts open schematic diagram for plan structure of the present utility model.

Referring to accompanying drawing: novel high-efficiency and energy-saving gas-cooker among the figure comprises exterior combustion chamber 10, inner combustion chamber 9 therebetween is set; Two combustion chambers are communicated with combustion gas injector 7,8 respectively; The ceramic porous plate 11 of concave surface is set on the combustion chamber, concave surface infra-red radiation wire netting 13 is set in the surface of ceramic wafer.

Among the figure: the inlet end of injector 7,8 is provided with gas nozzle 1, air distributes damper 3, reaches holddown spring 4.

In the embodiment that accompanying drawing provides, the ceramic porous plate 11 of concave surface is a double-decker; This concave surface ceramic wafer is by base plate and swash plate is bonding constitutes, and the ceramic porous plate 11 of concave surface is bonding and heat insulation by insulating moulding coating layer 18 at the position that contacts with kitchen range housing and inner combustion chamber; The edge of concave surface infra-red radiation wire netting 13 is fixed on the kitchen range housing by screw 17; The edge suitable for reading of kitchen range has insulation ring 14, has a nail 15 on insulation ring.

The course of work of the present utility model is such: open the feed channel control valve, kitchen range are in treats duty, closes air door 3, open the control valve of nozzle 1, the combustion gas ejection is lighted it with little fire, damper is to correct position, after tens seconds, kitchen range surface grate firing is red, sends infrared radiation heat, the user looks operating position, can distinguish or use two injectors simultaneously, and obtain little fire, big fire and full fire, the control valve on the time spent shut-off nozzle does not get final product.

The utility model efficient energy-saving gas burner distinguishing feature is as follows:

1. the combustion head of concave surface under onesize space, than plane area increased about 25%, can increase Big thermic load about 25% under same thermic load, can be dwindled the kitchen range volume.

2. the combustion head of concave surface designs according to the convex the bottom of a pan, make the bottom of a pan especially near combustion front can Take full advantage of the radiant heat of burner, bigger raising the thermal efficiency; Particularly use at Chinese meal stove, The thermal efficiency improves fairly obvious, can reach 63%, improves 3.15 times than standard GB/T 7824-8.

3. the employing of double-layer ceramic plate further mixes combustion gas and air, has improved efficiency of combustion, has increased anti-backfire function, has reduced the furnace chamber temperature, makes more thermal energy convert available heat to, thereby improves the thermal efficiency, reduces maintenance simultaneously and increases the service life.

4. adopt the concave surface heat radiation stable flame mesh that matches with combustion head, except steady flame effect, further the Enhanced Radiation Reduced Blast function increases about 10%.

5. double chamber, three kinds of power, little fire, big fire, full fire, the user can use each class according to circumstances, to reach satisfied result of use.

6. because this burner adopts flameless burning, double-layer ceramic plate, improve wind loading rating more than 4 times, these entity and individual to outdoor field work are particularly important.

7. owing to the kitchen range sufficient combustion, carbon monoxide is low in the flue gas; Flameless burning does not have oil, cigarette, no blacking pan, sanitation and hygiene.Reduce and pollute.

The suitable combustion gas kind of the utility model is many, and the pressure scope of application is wide, removes natural gas, outside the oil liquefied gas, biogas, mine gas gas, collection furnace gas, oil gas, coal gas are all applicable, and pressure is at the equal incendivity of 2000-20000Pa, even burn fully at 0.1-0.3MPa in the same old way.

Combustion gas kitchen range series by the utility model constitutes can be widely used in family, hotel, dining room and field work, because thermal efficiency height, obvious energy conservation has obvious social.
