Description

Self-pressure, high-efficience and safety stove

The utility model belongs to a kind of technological innovation of family expenses kitchen range.

Before the utility model was made, all there was following a kind of or several deficiencies in the various kitchen range of being seen use synthetic fuel on the market.Inflate as needs, it is bad to gasify, flame instability, and fuel is incomplete, pernicious gas is discharged, the kitchen range that particularly have do not have makes gaseous-pressure keep constant closed-circuit system, but valve safe in utilization, if hypertonia, safety valve is opened, emit fuel gas, meeting breaking out of fire explosion accident causes personnel's property loss.

The purpose of this utility model is, for overcoming the shortcoming that above-mentioned kitchen range exist, provide a kind of use novel synthetic fuel, pluralities of fuels such as methyl alcohol, ethanol, liquefied petroleum gas, utilize self-pressing type heating liquid level automatic principle of compensation, thereby reach gasification well, burning fully, flame stabilization, safe and reliable novel self-pressing type highly effective and safe kitchen range.

Fig. 1 is the structure principle chart of the utility model self-pressing type highly effective and safe kitchen range.(1) is electronic impulse ignition apparatus among the figure, (2) be the preheating combustable liquid pipe, (3) be preheating combustion liquid switch, (4) be Gas Pipe, (5) be the combustion gas by-pass cock, (6) are the combustion gas nozzle, and (7) are damper regulator, (8) be burner body, (9) be main burner port, (10) are hollow type annular heating and gasifying capsule, and (11) are the initial liquid level of heating and gasifying capsule, minimum heating liquid level when (12) being normal combustion, (13) be the preheated burning dish, (14) are gasification heating flame hole, and (15) are self-pressure type liquid return pipe, (16) be feed pipe, (17) be the sealing liquid filling hole, (18) are the liquid case, and (19) are liquid case liquid level, (20) be the high pressure pulse discharge head, (21) are micro pore igniting net sheet.

Technical characterictic of the present utility model is to be connected with self-pressure type liquid return pipe (15) between hollow type annular heating and gasifying capsule (10) and the liquid case (18), its principle is for utilizing self-pressing type heating and gasifying liquid level automatic adjustment circuit principle, thereby make gaseous-pressure remain on a stable state, reach flame stabilization, thermal efficiency height, safe and reliable purpose.

Specifically describe implementation of the present utility model below in conjunction with accompanying drawing.

With reference to Fig. 1, the utility model liquid case (18) has three liquid pipes, and preheating combustable liquid pipe (2) provides fuel to preheated burning dish (13), opens preheating combustion liquid switch (3), electronic impulse ignition apparatus (1) igniting simultaneously, and preheated burning dish (13) takes fire.Feed pipe (16) provides fuel for hollow type annular heating and gasifying capsule (10), after preheating dish (13) burning, fuel gasification in the gasification capsule, gas from Gas Pipe (4) through by-pass cock (5) and combustion gas nozzle (6) to burner body (8), light the gas of main burner port (9) this moment, and these kitchen range promptly take fire.The intensity that damper (7) can be regulated combustion flame.The 3rd pipe of liquid case (18) is self-pressure type liquid return pipe (15), and it links to each other with gasification capsule (10), and after the kitchen range burning, it plays self-pressing type heating liquid level autoregulation.This gas-cooker profile is identical with the general gas kitchen range, can make two kitchen ranges or single kitchen range, is combustable liquid tank in the middle of two kitchen ranges, and single kitchen range combustable liquid tank is in a side.

The utility model uses when initial the level mutually of liquid level (19) in the liquid level (11) in the medium spacing ring-shaped gasification capsule (10) and liquid case (18).After preheated burning dish (13) beginning preheating, combustion liquid temp in the hollow type annular heating and gasifying capsule (10) raises rapidly, begin gasification after reaching gasification temperature, because the rule that gas rises naturally, fuel gas after the gasification of combustion liquid constantly fills the top of hollow type annular heating and gasifying capsule (10), the also corresponding rising of pressure is heated liquid level this moment and is begun to descend under the effect of gas pressure, and this process can be finished in a short period of time.Open combustion gas by-pass cock (5) this moment, the i.e. ejection in burner body (8) of fuel gas, under the effect of preheating flare, main burner port (9) and gasification heating flame hole (14) take fire, and reach normal operating conditions rapidly.If the combustion liquid gasification rate in hollow type annular heating and gasifying capsule this moment (10) is too fast, gasification capsule top fuel gas pressure raises, the combustion liquid liquid level that is about to heating and gasifying is toward pressing down, thereby reduced the heating surface area of combustion liquid heating, gasification rate is reduced, pressure promptly can descend automatically, if the combustion liquid gasification rate in the hollow type annular heating and gasifying capsule (10) is slow excessively, gasification capsule top fuel gas hypotony, the heating liquid level can raise under the combustion action of hydraulic force of liquid case (18) lining automatically, thereby increased the heating surface area of combustion liquid heating, accelerated gasification rate, pressure promptly can rise automatically.Therefore whole gasification loop is among the automatic feedback recurrent state, and gaseous-pressure remained at stable status when the self-regulating principle of this self-pressing type heating liquid level can make kitchen range use, and reaches safety, effect efficiently.

The utility model self-pressing type highly effective and safe kitchen range medium spacing annular heating and gasifying capsule (10) in the burning course of work is among the flare heated condition in gasification heating flame hole (14) all the time, constantly heating, constantly gasification, fuel gas after the gasification and supply with main burner port (9) and the gasification heating flame hole (14) burning, kitchen range are among the optimum working cycles always like this, hypertonia can not take place, thereby the critical defect that causes security incident, so these kitchen range flame stabilization, safe and reliable, this is that the utility model is different from the most outstanding characteristics of various kitchen range in the past.

The utility model self-pressing type highly effective and safe kitchen range have an innovation in the high-voltage pulse igniting, utilize micro pore igniting net sheet (21) to solve this difficult problem in order to solve the problem of general liquid fuel in the high-voltage pulse ignition difficulties, to have designed.Its principle is, place the net sheet (21) that a slice has fine pores in preheated burning dish (13) medium dip, its high end is towards high pressure pulse discharge head (20), open preheating combustion liquid switch (3) during igniting earlier, fasten preheating combustion liquid switch (3) after treating to have in the preheated burning dish (13) an amount of combustion liquid, press electronic impulse ignition apparatus (1), high-voltage pulse power generation head (20) is promptly emitted electric spark to micro pore igniting net sheet (21), because micropore effect capillaceous, the humidity that combustion liquid is sucted just in time is beneficial on fire, therefore can be on fire when high-voltage pulse electric spark one net-fault sheet is high-end.The net sheet has a lot of little pores simultaneously, and the wall that constitutes little pore is very thin, and little high temperature of very easy generation is lighted liquid fuel under the effect of high electric field pulse spark.

The design of the utility model self-pressing type highly effective and safe kitchen range is unique, and rational in infrastructure, production technology is simple, is fit to produce in batches, has good market prospects and economic benefit.
