The gas-cooker core that the utility model provides also is provided with reflector on state fire holding cycle, have a plurality of steam vents on the reflector, and reflector can have effective reduction heat-energy losses.

And, between cover plate and preheating mixing chamber, also be provided with at least one packing ring, to regulate kitchen range core height.

And; packing ring, cover plate and the outside, fire holding cycle lower end have prominent ring; mixing chamber, packing ring, cover plate, fire holding cycle upper end are provided with and the close-fitting groove of prominent ring, and two parts that link to each other just can be closely linked by the prominent ring and the groove at interface position.

(3) beneficial effect

The gas-cooker core that the utility model provides is owing to have a preheating mixing chamber, and combustion gas is sprayed by through hole through fully mixing preheating after with air, thereby makes fuel gas buring more abundant, and while heat energy loss and toxic emission obviously reduce, not only energy-conservation but also environmental protection.

Among the figure: 1. preheating mixing chamber; 2. packing ring; 3. cover plate; 4. fire holding cycle; 5. reflector; 6. protective cover; 7. through hole; 8. ever-burning flame device; 9. go out fuel gas hole; 10. groove; 11. steam vent; 12. ever-burning flame tracheae; 13. fire emits; 14. air intake opening.

The specific embodiment

Below in conjunction with accompanying drawing, further describe implementation method of the present utility model, but be not used for limiting the claimed scope of the utility model.

As shown in Figure 1 and Figure 2, the gas-cooker core that the utility model provides is a preheating mixing chamber 1 in the bottom of kitchen range core, the lower end of mixing chamber 1 and upper end open, and sealing is tubular all around, and the lower end places on the kitchen range top.Have a packing ring 2 above the mixing chamber, packing ring 2 is used to regulate the height of kitchen range core, and is higher such as the kitchen range top, then can increase the quantity of packing ring 2, to increase height.It above the packing ring 2 cover plate 3, have some through holes 7 above the cover plate 3, have 72 through holes 7 in the present embodiment, be divided into two groups, the center that is positioned at cover plate 3 is on two circumference of round dot, wherein, interior ring is provided with 24 through holes 7, outer shroud is provided with 48 through holes 7, through hole 7 is horizontal by the angle of 75 degree, and the center that the bottom of through hole 7 point is distributed in cover plate 3 is on the circle of round dot, and, the axis and comprise the tangent line of described circle and the plane perpendicular to horizontal plane between be 15 ° angle.The central authorities of cover plate 3 are provided with ever-burning flame device 8, and this device comprises having ever-burning flame tracheae 12 that is positioned at cover plate 3 middle positions and the protective cover 6 that covers on outside the ever-burning flame tracheae 12 one on the sidewall of protective cover 6 and go out fuel gas hole 9, has an air intake opening 14 at its top.On cover plate 3, be provided with a fire holding cycle 4, be provided with a reflector 5 above the fire holding cycle 4, and on reflector 5, have a plurality of steam vents 11, be beneficial to exhaust gas discharging.Wherein, fire holding cycle 4 and reflector 5 all have the effect that the energy loss of preventing improves the heat energy utilization rate.
