Description

Liquid fuels Ranges

The utility model relates to a kind of kitchen range, especially a kind of liquid fuel cooking range.

The family of China more than 90% is fuel with faggot and coal still at present, and few part family uses oil product to be fuel.Coal and reserves sharply descend owing to excessive exploitation.As for oil liquefied gas, because the needs of ethylene project, civilian quantity delivered is fewer and feweri.Changing the domestic energy structure becomes the important topic of the world today.The novel liquid fuel that occurs is that employing is the ideal fuels of base material with the mixed alcohol in the recent period, and it is primary raw material with the alcohols, and adds a small amount of additive, is characterized in that the source is abundant, and low pressure is nontoxic, the calorific value height.Small and medium-sized cities, vast rural area and outlying district there is development prospect widely.

Use liquid fuel, at first will be to liquid fuel heat, reducing its viscosity, and then make the fuel vaporization atomizing.

It is that liquid fuel is injected in the thin copper tube of φ 3--5mm that present liquid fuel cooking range makes the method for liquid fuel refinement, evaporation atomizing, relies on external heat source that the red copper tube wall is heated the liquid fuel atomization that makes wherein, evaporates.For improving fogging degree, the length of copper tube that just must extend in limited space is so be that the copper tube dish is become collar plate shape, S type, bilayer or multilayer mostly.Because copper tube is very thin, very long, and there is foreign matter in liquid fuel itself, impurity, and contain high charcoal molecule in the fuel composition, thus in use inevitable blockage phenomenon, generally speaking, use a week, the two weeks copper tube is just blocked at most, can't dredge.

The liquid fuel cooking range that uses is because the defective in the valve design at present, gas after being difficult to not only control liquid but also control atomizing, there is serious seepage phenomenon, not only wasted fuel but also very dangerous, because the liquid fuel atomization process time is longer, generally need 3--15 minute to normal combustion in addition, not only bother very much from lighting kitchen range, and liquid fuel within do not have a large amount of noxious gas emissions before the normal combustion, and is bigger to the human injury.More there are many like products to need to atomize,, are difficult to apply as electricity, butagas, gasoline, alcohol etc. by other energy.

The purpose of this utility model provides a kind of new liquid fuel cooking range, and it avoids using thin copper tube, does not exist to cause the copper tube phenomenon of blocking when making liquid fuel atomization, solves the leakage problems of valve simultaneously and shortens preheating time.

The utility model is achieved in that the utility model liquid burning kitchen range, is a kind of eyes domestic gas kitchen range, and kitchen range comprise left and right sides kitchen range eye.The structure of left and right kitchen range eye is identical.Each kitchen range eye is by main control valve 1, pay by-pass valve control 2, main control valve drain pipe road 26, pay by-pass valve control fluid pipeline 15, combustion chamber 19, sealing vaporizer 20, combustion chamber fire lid 29, three-way connector 16, vaporizer feed pathway 22, vaporizer and go out vapour passage 23, gas pipeline 25, air door adjustment sheet 17, induction tunnel 18, air door fixed mount 34, combustion chamber fire lid fire hole 36, main control valve knob 9, pay by-pass valve control knob 8 and form (Fig. 1).
