Description
Technical field
The present invention relates to a kind of gas kitchen ranges, be specially adapted to stalk gas, between biogas and the liquefied gas, can change immediately, kitchen range also can general field.
Background technology
The problem of gas kitchen ranges field existence at present:
1. the natural gas of high heating value, coal gas, the gas kitchen ranges between the liquefied gas are can be general.With the low heat value stalk gas, the gas kitchen ranges of biogas is can not be general.Vast rural area living beings new forms of energy and biogas because of unit maintenance or because of mismanagement, in often stopping the supple of gas or steam, are made troubles to daily life, hope that very high fuel gas with low heat value kitchen range can be general.
2. present most of kitchen range all lean on the wind shelves to regulate air quantity, and oxygen supply helps so.Because the component of various combustion gas, air pressure is also inequality, only depends on the adjusting air quantity, and air-flow or minimizing gas supply amount are regulated proportioning, and combustion gas does not still reach clean-burning purpose.Therefore, the right gas in a large amount of ends is arranged, carbon deposit distributes in air, both sooting thes bottom of a pan, and contaminated environment wastes energy again.
3. present gas burner all is the metal cover board of sunflower formula much, leans on the wind shelves, and valve is regulated fired state.With the natural gas of high heating value, coal gas, liquefied gas are example, and under good blue look flame combustion state, surperficial flame temperature is about 700 ℃.Many combustion gas components do not reach burning-point under this temperature, cause the wasting of resources, contaminated environment.And low-calorie stalk gas, biogas is all the more so.
4. adopt ceramic sieve plate on the gas kitchen ranges head, to being to improve efficiency gas, the surperficial flame temperature of combustion gas is more than 900 ℃.The combustion gas component overwhelming majority can both burnout, and it can significantly improve using energy source, and rate reduces environmental pollution, and environmental protection is energy-conservation again.Goodies are opposite, and occupation rate of market is low.Reason is the kitchen range product structure, and quality quality and user psychology cause jointly.
1. present ceramic sieve plate all is to be fixed together with kitchen range, once broken sieve plate, most kitchen range are all wanted subscription rate, has not only drawn to ring user's normal life but also waste money.The part system of having added
The product quality of making the merchant is not high really, and the kitchen range internal cavity is too low, is prone to tempering because the high temperature width of cloth is penetrated the effect kitchen range of heat.The pottery sieve plate is met cold, and frangible happening occasionally drawn and rung the user and choose psychology.
2. after ceramic sieve plate kitchen range were lighted, the kitchen range face was red all the time, when you need little fire, was difficult to see adjustment state, usually its accent was gone out, and user emotion is big.
3. ceramic sieve plate kitchen range, because of the self structure problem, control valve open little, when air demand was little, one met the ambient windstream fluctuation, is easy to cause tempering, once the user is not at the scene, was prone to cause potential safety hazard.Because above great number of issues and worry are drawn greatly and have been rung sale.
Summary of the invention
Problem to existing gas kitchen ranges exists the invention provides a whole set of solution:
In the environment-friendly energy-saving cooker general at gas with high or low calorific value total solution: the valve body that gas kind selection function is arranged; The axial flow blower of forced air supply, power switch, the four-way appendix of band valve; On kitchen range, also have two kinds of activities, the metal cover board of interchangeable use and ceramic sieve plate.
Use the benefit of this kitchen range to be:
1。There is divergence type gas kind to select, the ignition switch valve as: gas kind selector valve assembly (89) ignition switch valve assembly (90) }; The superimposed type gas kind selector switch independent assembly of lighting a fire; The serial connection type gas kind selector switch independent assembly of lighting a fire; The parallel type gas kind selector switch independent assembly of lighting a fire supplies the user to select, and solves the gas kitchen ranges common question.
More than these assemblies are innovation important component parts in the kitchen range, be a kind of sign of difference general gas kitchen range.In these assemblies, general character part is in addition all arranged, for example; The superimposed type gas kind selector switch independent assembly of lighting a fire.Gas kind among the figure three is selected spool (66) number part.The Zhou Fangxiang along the venthole garden is drilled with a plurality of different-diameters at a certain distance, be fit to different gas kinds the combustion gas injection hole.As long as the location the is accurate spout of corresponding gas kind just can be through switch ignition use kitchen range.
Gas kind selection function valve has been arranged, just can let each gas kind gas kitchen ranges general.As long as choose above any suitable assembly type, can transform existing gas kitchen ranges, make it general with other gas kind, can design polytype again, different structure, the gas kitchen ranges that the gas kind is general.
2. with axial flow blower (22) air regulating board (20), induced duct (17).Ring air inlet pipe (13) transfers wind shelves (11) (15) to cooperate down in the endless belt gas inlet hole pipe (9) outside, and its can compulsoryly let airborne oxygen and combustion gas, in gas pipeline; In the gas burner (12); Do in the interlayer of ring ceramic sieve plate (25) (30) in outer repeatedly fully to mix preheating, burning.It can make ceramic sieve plate face reach the high temperature more than 900 ℃, significantly improves efficiency gas, reduces environmental pollution.Solution only relies on the wind shelves to regulate oxygen supply and helps so, makes fully combustion problem of combustion gas component.
The four-way pipe (1) of 3 band valves can connect two kinds of combustion gas of preparing use, opens a kind of combustion gas in a kind of pass, easily with solving combustion gas gas kind switching problem.When lacking a kind of combustion gas, can not draw the life that rings you yet.
Have two types on 4 kitchen ranges, metal cover board (48) (49).In, outer shroud pottery sieve plate (30) (25).Be energy-conserving and environment-protective, the main use has protective jacket to make monolithic devices, and be mobilizable, ceramic sieve plate.It is sturdy and durable, and spare part is done well, good random replacing.
This kitchen range internal cavity designs higherly, and ground distance＞50mm promptly is to have the high temperature width of cloth of ceramic sieve plate to penetrate between ring pottery sieve baseplane and the kitchen range internal cavity baseplane; There is blower fan to promote combustion gas; Can not cause the kitchen range tempering, solve user's worry and worry, potential safety hazard is secure.Just in case cause ceramic cover plate to damage, there is metal cover board subsequent use, can not draw and ring life, can not cause that kitchen range scrap yet, also obtain ceramic sieve plate spare part easily.If it is not directly perceived that the user feels to regulate stove fire, when can't see flare, also can change the ceramic sieve plate of interior ring into metal cover board and mix use, to satisfy user's need.
