CN2690752Y - Direct spray type hurner - Google Patents

Abstract

The utility model relates to a burner for a gas range, in particular to a direct spray type burner different from a prior burner. The utility model is characterized in that the bottom plate of the cup-shaped burner is provided with two gas orifices, and the bottom plate and the periphery of the bottom plate are provided with an air inlet orifice and a secondary air inlet orifice; the bottom plate of the burner is provided with a heat dispersion groove, and the bottom of the heat dispersion groove is provided with a concave overflow collecting groove, and a cop fire cap is removed. After the fire striking of the gas, the gas is directly sprayed and burns the bottom of a pan; the gas is not kept to cause insufficient combustion; the thick and heavy cop fire cap does not need to be heated for making the heat efficiency relatively improve; a temper phenomenon and a blasting phenomenon don't happen.

Description

The direct injection combustion device

Technical field

The utility model relates to a kind of burner of gas kitchen ranges, especially refers to a kind of direct injection combustion device that is applicable to the direct projection jet combustion of various gas kitchen ranges.

Background technology

In recent years, gas kitchen ranges enters huge numbers of families, and is quite universal, and the form of kitchen range is also varied.But the burner of traditional gas kitchen ranges all has Tong Huogai, and promptly the fuel gas that feeds from pipeline is introduced into the air chamber diffusion of the burner of peviform, sprays from the fiery aperture that covers of the copper on top then.What have replaces small garden hole with outgassing groove, is the efficient gas burner of ZL02231345 as my patent No. of authorizing on June 4th, 2003 of application, then is the Tong Huogai that has the umbrella shape outgassing groove.During burning, combustion gas becomes after the sparking and fills the air shape flame from venthole or outgassing groove ejection.The effect of copper fire lid, its original idea is can disperse at air chamber after combustion gas is stopped, spray from venthole (groove) equably, hardly realize that combustion gas is when being subjected to Tong Huogai and stopping, some combustion gas is trapped in the air chamber bottom, easily cause burning insufficient, the concentration of pernicious gases such as carbon monoxide is increased, and very easily produce the tempering and the phenomenon of blowing out.Because flame at the bottom of the heating kettle, also must heat thick and heavy Tong Huogai, its thermal efficiency also reduces relatively again.Therefore, people are in the cooking practice, and expectation has the novel burner that can make full use of the fuel gas heat to come out, and as the nozzle of blowtorch, combustion gas can be burnt to the bottom of a pan once exporting in direct projection especially.

The utility model content

The purpose of this utility model provides a kind of combustion gas directly sprays to the bottom of a pan burning from nozzle exit direct injection combustion device, save the Tong Huogai of barrier effect, with deficiency and the defective that overcomes conventional burners in the background technology, reduce the generation of pernicious gas and improve the thermal efficiency.

The technical scheme that the utility model adopted is: burner comprises body, air inlet pipe, fumarole, igniter and flame-out automatic safety device.Also comprise base plate, fresh air inlet, overflow feeder and body radiating groove and the secondary intake opening on every side on the body, it is characterized in that, the Tong Huogai that does not have conventional burners, combustion gas is not stopped, but direct projection ejection burning after the sparking, and because of being provided with secondary intake opening, so fuel gas buring is abundant, can not produce pernicious gas, and heat is fully used.Because of being annular groove between body base plate and the body wall, can collect the liquid of overflow when boiling again, and be provided with flame-out automatic safety device, therefore, the utility model not only thermal efficiency improves relatively, and safety and sanitation.

The specific embodiment

As shown in Figure 1, combustion gas enters from air inlet pipe 4, from fumarole 6 direct projections ejection, because of base plate 2 is provided with fresh air inlet 10, so combustion gas has enough comburant oxygens, lights through sparking, and the combustion gas direct projection sprays to the bottom of a pan, and firepower is more prosperous, just as the spray gun of blowtorch.Simultaneously, the secondary intake opening 7 around the body 1 also helps combustion gas fully to burn, thereby can not produce pernicious gas, has the minority flare also can burn to the bottom of a pan by the radiating groove around the body 19, and heat is fully used.If the purpose of two fumaroles 6 is to regulate flame size, when call for fire was big, two fumaroles 6 were simultaneously jet, when needs moderate heat or little fire, can regulate arbitrarily by the valve 5 of gauge tap.If liquid has a little to overflow in the pot, can collect in the overflow feeder 3 of burner spill, and be dryouied rapidly; therefore can not make fray-out of flame because of overflow; while can be safer during use because of flame-out automatic safety device 11 is housed, and more do not have the tempering and the phenomenon of blowing out and take place.

Claims (4)
