Abstract

The utility model relates to a civil gas range which is characterized in that a burner which is composed of a head and an ejector is additionally provided with a blade flow guiding disk, a vortex flow disk, and a by-pass gas inlet pipe. The air can be preheated by making use of residual heat, and part fume can be newly led into the ejector to be mixed with the gas. The mixing gas mixed by the preheated air, the part fume and the gas is sprayed, and is sprayed out from a small hole on the head of the burner to be burnt. Thus, the heat efficiency is raised, the energy is saved, and the pollution is reduced.

Description

Civil gas stove

The utility model is a kind of improved civil gas stove.

Existing civil gas stove adopts atmospheric burner mostly and since an atmospheric gas kitchen range premix part air, rather than the required air that all burns, so flame intensity, ignition temperature all is restricted, not only the thermal efficiency is low but also pollution is comparatively serious

The purpose of this utility model provides a kind of thermal efficiency height and pollutes little civil gas stove.

The purpose of this utility model is achieved in that setting up blade flow guiding disc and eddy-current disc on the civil gas stove now, utilizes waste heat to add hot-air, makes the partial combustion flue gas obtain second-time burning, just can improve the thermal efficiency and the reduction pollution to environment widely.

The utility model is simple in structure, and is safe and reliable, and not only the thermal efficiency is high but also pollute for a short time, is desirable gas appliance.

Now in conjunction with the accompanying drawings civil gas stove that the utility model is carried is further described.

Fig. 1, Fig. 2 are the schematic diagrames of civil gas stove that the utility model is carried.From Fig. 1, among Fig. 2 as can be seen, civil gas stove that the utility model is carried is mainly by bypath air air inlet pipe 1, base plate 2, eddy-current disc 3, vane type flow guiding disc 4, panel 5, supporting leg 6, burner head 10, burner injector 11 compositions such as grade, in the flow guiding disc 4 below the panel 5 heat exchanger plate 8 is arranged, several blades 7 have been arranged along dish shell 18 peripheries, tip with respect to each blade 7 all has aperture 14 on heat exchanger plate 8, be provided with eddy-current disc 3 below the flow guiding disc 4, spiral vortex plate 9 is arranged in the eddy-current disc 3, be helicla flute 16 between the adjacent spiral vortex plate 9, aperture 14 communicates with helicla flute 16, not end corresponding to helicla flute 16, having hole 17 on base plate 2 communicates with bypath air air inlet pipe 1 below the base plate 2, the other end of bypath air air inlet pipe 1 communicates with injector 11, and Air-regulating valves 13 is housed on it.

When gas-cooker is worked, combustion gas is under certain pressure, enter injector 11 with certain flow velocity from gas nozzle 12 ejections, injector 11 generation vacuum suction primary airs and combustion gas are mixed in injector 11, gaseous mixture burns from fire hole 15 ejections of burner head 10, in combustion process, primary air and partial fume are under the water conservancy diversion of the guide vane 7 between panel 5 and the heat exchanger plate 8, enter helicla flute 16 from aperture 14, by the outer ring to the inner ring screw, in this flow process, primary air be preheated and and partial fume 17 enter bypath air air inlet pipe 1 through the hole, enter injector 11 and combustion gas mixing again, mist is burnt by fire hole 15 ejections of burner head 10, the size of preheated air tolerance has so just reached the raising thermal efficiency by Air-regulating valves 13 controls, reduce and pollute, the purpose of energy savings.
