Abstract

The invention provides a gas stove burner which comprises a gas inlet and a burning chamber. A plurality of burning holes communicated with the outside are formed in the burning chamber, a pressure boosting chamber is further fixed outside the burning chamber, the gas inlet pipe is communicated with the pressure boosting chamber, the pressure boosting chamber is communicated with the burning chamber through a connecting pipe, the pressure boosting chamber extends to form a high-pressure igniting pipe, an inlet of the high-pressure igniting pipe is communicated with the pressure boosting chamber, and an outlet of the high-pressure igniting pipe is communicated with the outside of the pressure boosting chamber. Gas is conveyed into the pressure boosting chamber through the gas inlet pipe; one part of gas is conveyed into the burning chamber through the connecting pipe, flows out of the outer side of the gas stove burner through the burning holes and is ignited by an external igniting device; the other part of gas is outputted through the high-pressure igniting pipe communicated with the pressure boosting chamber; the gas outputted by the high-pressure igniting pipe can be ignited by flame above the burning holes; the pressure boosting chamber is heated by flame at the outlet of the high-pressure igniting pipe; the temperature and the pressure of gas entering the pressure boosting chamber are improved; and gas flowing out of the burning holes can be burned more fully.

Description

Burner for gas stove

Technical field

The present invention relates to a kind of burner for gas stove.

Background technology

Current most gas-cookers all adopt atmospheric burning type mode, and flammable premixed gas body does not rely on an other burning things which may cause a fire disaster condition ignition, i.e. involuntary ignition.During involuntary ignition, in order to make flameholding, not de-fire, the partial air needed for a premix, the shortcomings such as therefore there is burning abundant not, combustion velocity is slow, and flame is long, make ignition temperature and combustion intensity be restricted.Above atmospheric burning type is mainly with to streamed heat transfer, and such as Chinese dish cooking oven just requires that thermic load is large, and the bottom of a pan usable floor area is less, so just be unfavorable for carrying out effective heat exchange within the very first time, major part heat loses with flue gas, and therefore make efficiency reduce, energy waste is serious.

Summary of the invention

Technical problem to be solved by this invention is to provide good, the rational in infrastructure burner for gas stove of a kind of combustion efficiency.

For solving the problems of the technologies described above, the invention provides a kind of burner for gas stove, comprise air inlet pipe and combustion chamber, combustion chamber has the some burner ports communicated with outside, and be also fixed with pumping chamber outside combustion chamber, air inlet pipe is communicated with pumping chamber, pumping chamber is by tube connector and combustion chamber, described pumping chamber is extended with high voltage ignition pipe, and the import of high voltage ignition pipe is communicated with increase room, and the outlet of high voltage ignition pipe communicates with outside, pumping chamber.

After adopting such structure, combustion gas inputs in pumping chamber through air inlet pipe, and a part of combustion gas is delivered in combustion chamber by tube connector, and flows out outside this burner for gas stove by burner port, and combustion gas is lighted by outside ignition device; The combustion gas of another part is exported by the high voltage ignition pipe be communicated with pumping chamber, high voltage ignition pipe export combustion gas and burned hole above flame light, the flame heating pumping chamber in high voltage ignition pipe exit, make the fuel gas temperature rising, the pressure increase that enter pumping chamber, the spontaneous combustion phase shortens at high temperature under high pressure in combustion gas, makes from burner port outflow fuel gas buring more abundant.

Pumping chamber's extenal fixation of this burner for gas stove has inverted drainage to bore, and the summit of drainage cone is near high voltage ignition pipe exit; After adopting such structure, drainage cone can make the flare of high voltage ignition pipe along drainage cone outer wall slightly close to pumping chamber's inwall, make flame heat pumping chamber's area evenly.

The combustion chamber of this burner for gas stove is toroidal combustion chamber, and pumping chamber is also annular plenum, and pumping chamber is fixed on inside combustion chamber, and high voltage ignition pipe extends to inside pumping chamber, and drainage cone is fixed on inside pumping chamber; After adopting such structure, make the more reasonable structure of this burner for gas stove.

Accompanying drawing explanation

Fig. 1 is the top view of this burner for gas stove embodiment.

Fig. 2 is that Fig. 1 is along A-A to sectional view.

Detailed description of the invention

As shown in Fig. 1 to 2

This burner for gas stove comprises air inlet pipe 1, pumping chamber 4, tube connector 6, high voltage ignition pipe 7, drainage cone 8 and combustion chamber 2.

Combustion chamber 2 is toroidal combustion chamber 2, and the upper cover uniform circular of combustion chamber 2 is distributed with multiple burner port 3.

Pumping chamber 4 is also annular plenum 4, the external diameter of pumping chamber 4 is less than the internal diameter of combustion chamber 2, pumping chamber 4 is weldingly fixed on inside combustion chamber 2 by three bracing frames 5, air inlet pipe 1 is communicated with pumping chamber 4, pumping chamber 4 is connected with combustion chamber 2 by tube connector 6, pumping chamber 4 is outward extended with high voltage ignition pipe 7, the import of high voltage ignition pipe 7 is communicated with pumping chamber 4, the outlet of high voltage ignition pipe 7 is in inside pumping chamber 4, inverted drainage cone 8 is welded on inside pumping chamber 4 by fixed mount 9, and on the upside of the outlet being in high voltage ignition pipe 7, the mouth of pipe area of section of air inlet pipe 1 is not less than the area of section sum of tube connector 6 and high voltage ignition pipe 7.

During use, combustion gas inputs in pumping chamber 4 through air inlet pipe 1, and a part of combustion gas is delivered in combustion chamber 2 by tube connector 6, and flows out outside this burner for gas stove by burner port 3, and combustion gas is lighted by outside ignition device, burns above burner port 3; The combustion gas of another part is exported by the high voltage ignition pipe 7 be communicated with pumping chamber 4, high voltage ignition pipe 7 export combustion gas and burned hole 3 above flame light, and it is slightly close to pumping chamber 4 inwall that the flare of flame bores 8 outer walls along drainage, the flame heating pumping chamber 4 in high voltage ignition pipe 7 exit, the fuel gas temperature making to enter pumping chamber 4 raises, pressure increase, makes to flow out fuel gas buring from burner port 3 more abundant.

Above-described is only one embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, and these also should be considered as belonging to protection scope of the present invention.
