Description

Liquid fuel cooking range

The utility model relates to a kind of liquid fuel cooking range, especially a kind of civilian normal pressure liquid fuel cooking range.

Existing liquid fuel cooking range generally is by gravity the liquid fuel in the fuel tank to be injected vaporizer under normal pressure, thereby cause fuel supplement deficiency in the vaporizer often, and in order to guarantee the general all modes of employing dish intestines copper pipe of vaporization effect, and tortuous long and narrow pipeline is easy to the carbon knot, stops up, and the problem of this two aspect has just caused the tempering, flame-out of kitchen range.

For this reason, the purpose of this utility model is to overcome the deficiency of prior art, and provide a kind of can be automatically to fuel tank pressurization to guarantee vaporizer fuel abundance, and under the situation that does not adopt dish intestines copper pipe, fuel is fully vaporized, each connecting pipe is smooth and easy, the liquid fuel cooking range of no tempering, flame-out phenomenon.

The technical scheme that realizes the utility model purpose is a kind of liquid fuel cooking range, especially a kind of civilian normal pressure liquid fuel cooking range, comprise fuel tank, the vaporizer that is communicated with fuel tank by pipeline, make the preheating dish of liquid fuel evaporation, and with the vaporization liquid fuel be transported to the pipeline of combustion chambers burn and the valve that in pipeline, is provided with, it is upper and lower two-layer that its special character is that vaporizer is divided into, the upper strata is communicated with fuel tank, combustion chamber respectively by two pipelines, and lower floor then is communicated with the top and the bottom of fuel tank respectively by two pipelines.

And vaporizer is positioned at preheating dish top, burned chamber around, the vaporizer top is a convex, places kitchen range top central authorities.

And, from the pipeline of vaporizer output gas, being provided with valve, valve is communicated with combustion chamber and fuel tank respectively by pipeline.

Because vaporizer is divided into two-layer, the upper strata by pipeline respectively with fuel tank, the combustion chamber is communicated with, lower floor is communicated in the upper and lower of fuel tank respectively by pipeline, at first fuel enters on the vaporizer by gravity, lower floor, after the preheating dish of vaporizer below heats vaporizer, liquid fuel in the vaporizer is partly vaporized, gas and partially liq that lower floor produces are sent back to fuel tank, give the pressurization of the liquid fuel in the fuel tank, and the gas part that while vaporizer upper strata produces is delivered to combustion chambers burn, another part electricity is sent back to fuel tank, increase the pressure in the fuel tank, thereby guaranteed replenishing of vaporizer fuel, in addition, vaporizer is positioned at preheating dish top, burned on every side chamber around, and the vaporizer top is convex, places kitchen range central authorities, vaporizer is as being wrapped up by a fireball like this, heating surface area is big, and the liquid fuel evaporation in it is quite abundant, and mode that needn't employing dish intestines copper pipe guarantees vaporization effect, thereby can not produce pipeline carbon knot, stop up, cause tempering, flame-out.

The utility model is described in further detail below with reference to accompanying drawing.

Accompanying drawing is a cutaway view of the present utility model

By accompanying drawing as can be known, liquid fuel cooking range described in the utility model is by fuel tank 1, vaporizer 10, combustion chamber 9, preheating dish 5 and valve 4,5, pipeline 2,3,6,14 compositions such as grade, vaporizer 10 is divided into, two-layer down, fuel in the fuel tank 1 is respectively by pipeline 3, on the 2 inflow vaporizers, lower floor 11,12, gas in the vaporizer 10 is then by pipeline 14,6 are sent to fuel tank 1 and combustion chamber 9, when the pipeline approach is longer, can utilize pipe joint to connect, as the pipe joint in the pipeline 3 16, the below of vaporizer 10 is a preheating dish 5, the pipeline 13 of being drawn by fuel tank 1 stretches in the preheating dish 5, be provided with a valve 4 in the pipeline 13, during use, at first press turn-knob and open valve 4, the liquid fuel of fuel tank 1 is dropped in the preheating dish 5, make the conducting of pulse firing loop when turn-knob is pressed and produce pulsed arc, light the liquid fuel that is dropped in the preheating dish 5, the heat that fuel produces is with the partially liq carburretion in the vaporizer 10, gas in the vaporizer lower floor 12 and partially liq are got back to fuel tank 1 by pipeline 14, increase fuel tank 1 in pressure, make the fuel of vaporizer 10 obtain in time replenishing, the gas on vaporizer upper strata 11 is by pipeline 6,15 are sent to combustion chamber 9, valve 7 in the pipeline 6 is used for regulating the size of steam flow amount, if on valve 7, establish a pipeline 8 that leads to fuel tank 1 top more, then can also send the part gas on vaporizer upper strata 11 back to fuel tank 1 by control valve 7, make the fuel of vaporizer 10 obtain better replenishing, the gas that is sent to combustion chamber 1 is after vapour-liquid is isolated, light by the flare that preheating dish 5 strings, for increasing heating surface area, the top of vaporizer 10 is an overshooting shape, place the kitchen range middle part, 9 of burned chambers of whole vaporizer around, accompanying drawing is depicted as the single head kitchen range, if at the opposite side of fuel tank 1, be symmetrical arranged vaporizer 10 and each road pipeline can become the double end kitchen range.
