In the prior art, known have following a kind of gas burner (with reference to patent documentation 1: the real public clear 61-26734 communique (figure one, figure two) of Japan).Central portion at the main burner of ring-type is provided with central burner, the gaseous mixture of combustion gas and primary air is distributed to main burner and central burner, and make its burning.
In this gas burner, be communicated with from the gas feed path of the inner radial extension of distributing chamber of central burner and the annular distribution chamber of the inner formation of main burner.The gaseous mixture that is fed in the main burner also is fed in the central burner via the gas feed path.
Yet, gaseous mixture being supplied in the structure of central burner through main burner, a part of gaseous mixture in the distributing chamber of main burner can flow to central burner.When going for big firepower, the mobile increase of above-mentioned gaseous mixture receives this influence of flowing, and the gaseous mixture on the annular distribution chamber complete cycle of main burner can produce problem pockety.
Summary of the invention
In view of the above problems, the object of the present invention is to provide and a kind ofly can be reliably gaseous mixture is distributed to main burner and central burner and do not received the influence of firepower size and obtain the gas burner of good combustion.
Gas burner of the present invention possesses: the main burner of ring-type; Central burner, it is configured in the central portion of this main burner; Gas imports the chamber, and it connects the bottom that is arranged on this central burner across dividing wall; The throat of tubular, its upstream extremity becomes open state and relative with the nozzle of ejection combustion gas, thereby can bring primary air into combustion gas, the downstream of this throat imports the chamber at said gas bottom to above opening; A plurality of main burners are used the gas feed path; It imports the radial extension of chamber along continuous straight runs from said gas, is connected with said main burner, and will imports to the indoor combustion gas of said gas importing and the gaseous mixture of primary air supplies to said main burner from said throat; And a plurality of central burner are used the gas feed path; It obtains the gaseous mixture that said gas imports the chamber from the inlet in the upper shed of said dividing wall lower surface; And this gaseous mixture supplied to said central burning part; This gas burner is characterised in that; In the outside of the opening region facing of throat said dividing wall lower surface and said downstream and between adjacent each other said main burner is with the gas feed path, the inlet of said central burner gas feed path is set, in said central burner with the inlet of gas feed path in the outside on the horizontal direction and between mutual adjacent said main burner is with the gas feed path; Side walls is set, and the gaseous mixture mobile along the lower surface of said dividing wall can collide on this side walls.
According to the present invention, at first, at nozzle during towards the upstream extremity of said throat ejection combustion gas; Because of flowing of this combustion gas; Ambient air is rolled in the combustion gas as the primary air of burning usefulness, and enters in the throat, and the gaseous mixture of combustion gas and primary air enters into said gas from throat and imports the chamber.
The downstream of throat imports the chamber at gas bottom to above opening.Therefore, entering into gas imports indoor gaseous mixture and produces collision with the lower surface that is positioned at the said dividing wall directly over throat's downstream.Form along the lower surface of dividing wall to the flowing of horizontal direction diffusion with gaseous mixture after the dividing wall lower surface collision, and flow to said main burner and use the gas feed path with gas feed path and said central burner.
Flow to main burner and use the gas feed path through main burner, enter in the main burner with the gaseous mixture of gas feed path.Because main burner is provided with a plurality ofly with the gas feed path with radial, by the main burner inside of leading effectively, and forms uniform distribution along the complete cycle of the main burner of ring-type through the gaseous mixture of these main burners after with the gas feed path.
On the other hand, flowing to main burner then flows to central burner with the gaseous mixture beyond the gas feed path and uses the gas feed path.At this moment; Because central burner is arranged on adjacent each other main burner with between the gas feed path with the inlet of gas feed path; So the flowing of gaseous mixture that can prevent to flow to central burner gas feed path produces obstruction to flowing to main burner with the gaseous mixture of gas feed path.
Here, in the present invention, the central burner outside with the opening region facing throat downstream that be positioned at the dividing wall lower surface with the inlet of gas feed path.Therefore, the gaseous mixture that flows to the top from throat's downstream be not do not change its flow direction and linearity enter into central burner with the gas feed path in, prevented that gaseous mixture from exceedingly being supplied to central burner.
But; Because central burner is with the inlet of the gas feed path lower surface opening to dividing wall; So, when particularly the flow velocity of gaseous mixture is very fast under the situation of big firepower burning, can't make the flow direction of this gaseous mixture that big change is arranged; Thereby said gaseous mixture can enter into central burner hardly with feed path, and just in the horizontal direction through this inlet.
Therefore, in the present invention, said side walls is set, makes to flow to central burner and collide on the side walls with the gaseous mixture of gas feed path.In view of the above, can not enter into the gaseous mixture that central burner just passes through with the gas feed path in the horizontal direction and collide side walls, change its flow direction, and flow to central burner and use the gas feed path.So,, can enough gaseous mixtures be supplied to central burner even when the flow velocity of gaseous mixture is very fast under the situation of big firepower burning.
Like this,, can reliably gaseous mixture be distributed to main burner and central burner, make gaseous mixture be distributed in main burner and the central burner neither too much nor too littlely, and can not receive the influence of firepower size and obtain good burning according to the present invention.
In addition, in the present invention, preferably on the position corresponding said dividing wall lower surface, be provided with towards the protrusion of this opening protuberance with opening said throat downstream.This protrusion forms staggered floor in its periphery.In view of the above,, on the protrusion of dividing wall lower surface, form from the collision of the gaseous mixture of throat along raised walls flowing to horizontal proliferation.Then, flowing to said main burner promotes it to flow with the gaseous mixture of gas feed path because of the staggered floor of protrusion periphery with gas feed path and said central burner.So, successfully supplied in main burner and the central burner with the gas feed path with gas feed path and central burner through main burner from the gaseous mixture of throat, can obtain more good burning.
