Description

Gas-cooker kitchen range core

Technical field

The utility model belongs to a kind of gas-cooker kitchen range core, is used for coal gas, liquefied gas, methane cooker.

Background technology

China's gas kitchen ranges brand is numerous, but all adopts horizontal injector, the atmospheric burning type method, and kitchen range core outer shroud air-flow is big, and firepower is big, and central gas stream is little, and firepower is little.The used cooker actual conditions of Modern Family are, the food capacity at cooker center causes the collocation of fire temperature imappropriate greater than the several times of periphery, and thermal efficiency utilization is not high, and outwards heat radiation is big, and the time of boiling is long, and it is many to consume gas.Secondly its damper and fumarole are located at portion in the kitchen range top, according to the variation damper of makings air pressure, because inside door is positioned at the kitchen range bottom, regulates, cleans pore inconvenience.Several in the market simple energy-economized kitchen range cores, though energy-conservation, there is variety of issue in using, the firm stable poor performance, take off fire, fire extinguishing easily, service life is not long, stops up pore easily, and pipeline junction leaks gas easily, the security performance instability.China Patent No. 01205710X, 022153284X, the structure of two special parts all is to utilize screw copper pipe and movable screw, the kitchen range center is introduced in combustion gas, and copper pipe reaches 2000 millimeters, refills the core of doing the cooking, just do the point of safes of whole kitchen range core by the screw of 8 millimeters of length 8 mm dias, do the kitchen range health in the use, will make the kitchen range deflection unintentionally, or fluctuate, cause each connecting portion turn gas leakage of kitchen range core, the personal safety accident easily takes place in gas leakage.Secondly, jet nozzle is arranged on fresh air inlet and makes, and has constituted the spill nozzle, use will cause firepower to reduce soon or do not have fire, the dregs of fat flow to or plug nozzle on venthole, the maintenance rate height.Its three, it is improper that damper is set, mixture pipe (being main valve) is located on the nozzle, swings up and down, and does not does not increase and decrease the fresh air inlet area, because of 4 millimeter of a fresh air inlet diameter, about adjustable range 3-4 silk, DeGrain.Its four, main valve is the hollow circuit cylinder body structure, it is bad to vaporize like this.Because of combustion gas sprays from nozzle, bring primary air mixing vaporization into, little big from vaporization concentration to vaporization concentration, inhomogeneous from mixing air to mixing, so the main valve mixing chamber should be taked down the little circular hollow of big vertebra that, the gasification cleanliness progressively strengthens, and combustion gas is better in air atomizing, and burning is just more abundant.Its five, the shower nozzle setting does not have burning point improper, flame can not be stablized, and easily takes off fire, fire extinguishing, as air pressure more greatly, with regard to auto extinguishing, as the air intake flow is reduced with regard to incomplete combustion.Its six, each breather line loose joint junction, position is improper, design all be flat mouthful, adds packing ring with nut and seals.

Summary of the invention

The purpose of this utility model provides a kind of energy savings, and security performance is stable, easy to operate, the gas-cooker core of long service life.

Technical solutions of the utility model are: horizontal jet kitchen range and inside door on the original kitchen range switch are pulled down, directly connect a copper pipe with the loose joint screw, the center of kitchen range is guided in combustion gas by copper pipe, make combustion gas turn to the top by L shaped connector, adopt vertical jet and vertical vertebra shape induction tunnel, the induction tunnel upper end is provided with burner, the induction tunnel lower end is provided with the stable cover of sitting, the stable cover lower end of sitting connects the nozzle screw rod, the support that seat cover bottom has been provided with fixedly kitchen range core effect is connected with stove, be provided with a plurality of fresh air inlets around the injection organ pipe lower end, and corresponding one by one with seat cover bottom fresh air inlet.The nozzle face of nozzle screw rod upper end is a round convex shape, and the nozzle face periphery overlaps fresh air inlet and flush with sitting, and the smoke particle on the nozzle face can be discharged from air inlet, does not block pore.Induction tunnel under the burner is provided with cover, and cover is provided with the cross-ventilation hole,

Induction tunnel is up big and down small hollow cone body, and be inserted in the conical cover for seat that is mated the bottom, and a plurality of corresponding air admission holes are arranged at induction tunnel bottom and cover for seat bottom, and the rotation induction tunnel can be regulated the air admission hole size.

There is an alignment pin in the outside, induction tunnel [14] middle and lower part, can insert a L shaped groove of cover for seat, makes induction tunnel turn to the location; To regulate the size of an intake.Ignition switch is connected with pulser and flame-out protection device.

The burner upper surface is a spill, is provided with a plurality of circular holes that play combustion-supporting effect.Pass burner internal edges edge on the induction tunnel outer, can establish pulse and light pin on one side, it is flame-out to establish electroheat pair on one side, control air-flow protection device.

Crossing the tracheae two ends is toroidal, and connected port is taper, and connection cooperatively interacts.

The utility model advantage is the fractional energy savings height, rotates by the moving induction tunnel of surfaces of revolution cover tape, regulates the fresh air inlet size of bottom, and is easy to operate and since nozzle screw rod top have one fixedly the support of kitchen range core be connected with stove, the kitchen range core can not swung.Long service life, simple in structure, security performance is more stable.
