Technical field
The present invention relates to the main and side burner of a kind of main use on gas furnace.
Background technology
In the past, as this main and side burner, as everyone knows, the main burner top cap that has auxiliary burner top cap and surround the ring-type of auxiliary burner top cap, be formed with a plurality of auxiliary burner glory holes in the surrounding wall portion of auxiliary burner top cap to have mode at interval in a circumferential direction, and be formed with a plurality of main burner glory holes to have mode at interval in a circumferential direction in the surrounding wall portion of the outer circumferential side of main burner top cap.And this main and side burner generally is to adopt by igniter to light a fire, make flame to prolong the form that burnings (extension is burnt) arrives the opposing party's glory hole to a side of main burner and auxiliary burner.
Thus, upper wall portions at main burner top cap offers the otch glory hole (reference: for example of extending diametrically that the flame that is used between main burner glory hole and the auxiliary burner glory hole prolongs burning, Japan is real to open flat 1-144614 communique, speciallys permit communique No. 2506954).Otch glory hole on this burner is the cutting of being undertaken by the outer circumferential side from main burner top cap, and form with the form of the excircle part of the main burner top cap of cutting apart the surrounding wall portion that comprises outer circumferential side fully.
Yet, if fully cut apart the excircle part of main burner top cap like this, then can make the otch glory hole narrow down and become in a narrow margin because of the thermal expansion of main burner top cap towards radial outside, thereby can reduce from the gas quantity of otch glory hole ejection, causing flame between main burner glory hole and the auxiliary burner glory hole to prolong burning can not carry out well.Particularly, at main burner top cap is to be formed than the also big material of its burner head of mounting by coefficient of thermal expansion, the thermal expansion of main burner top cap is limited by the fitting portion with respect to interior all sides of main burner head again, main burner top cap all can not carry out the occasion of impartial thermal expansion the time, the otch glory hole then will become the escape portion of the thermal expansion of main burner top cap, the otch glory hole just is easy to become narrow like this, causes flame to prolong the deterioration of burning property.
Summary of the invention
The present invention in view of the above-mentioned problems, its purpose is to provide a kind of otch glory hole that prevents that the thermal expansion because of main burner from causing to narrow down, and can keep the main and side burner that flame prolongs burning property well.
For achieving the above object, in the present invention, the main burner top cap that main and side burner has auxiliary burner top cap and surrounds the ring-type of auxiliary burner top cap, surrounding wall portion at auxiliary burner top cap, to exist spaced form to form a plurality of auxiliary burner glory holes in a circumferential direction, but also, form a plurality of main burner glory holes there to be spaced form in a circumferential direction in the surrounding wall portion of the outer circumferential side of main burner top cap; And, offer the flame that is used between main burner glory hole and the auxiliary burner glory hole and prolong and burn and extend radially otch glory hole in the upper wall portions of main burner top cap; On the excircle part of main burner top cap, there is the form of the linking part of the two sides that link the otch glory hole to form the otch glory hole with residual.
According to above-mentioned formation, in case the stress effect that has the wide cut that makes the otch glory hole because of the thermal expansion of main burner top cap to narrow down, compression stress then affacts on the linking part under residual.And this compression stress acts on as resistance, has suppressed the otch glory hole like this to become narrow, prolongs burning thereby kept flame well.
At this, if wish that further improving flame prolongs burning, then the form with the outer peripheral edges that reach main burner top cap forms the otch glory hole, so that the otch glory hole approaches the main burner glory hole that forms on the outer circumferential side surrounding wall portion.This occasion, if on the cap of main burner top, form the words of otch glory hole with the form of formation position of main burner glory hole by any one, then and the upper end of main burner glory hole between the only residual linking part that a little is arranged, will become narrow because of insufficient strength causes fully suppressing the otch glory hole like this.
To this, if form the otch glory hole with top by the arbitrary wall part between the main burner glory hole of the outer circumferential side surrounding wall portion of main burner top cap and the form that reaches the outer peripheral edges of main burner top cap, then can give wall part residual as linking part, thereby guarantee the intensity of linking part, suppressed narrowing down of otch glory hole so effectively.
Yet with wall part under the residual occasion, the position that flows into the radially outermost end of scope with respect to the combustion gas of otch glory hole becomes the position of the inner peripheral surface of wall part in this wise.At this, if wish to increase around to the gas quantity of the outer end of the otch glory hole of the outer peripheral edges position that is in main burner top cap, prolong burning, then shorten as much as possible with respect to the distance between the outer peripheral edges of the position of the radially outermost end of the combustion gas inflow scope of otch glory hole and main burner top cap to improve flame.This occasion, if the inner peripheral surface of next door portion forms the depressed part that is recessed to radial outside to reach otch glory hole ground, because combustion gas flows into the otch glory hole from depressed part, so the outer peripheral edges of main burner top cap are approached in the position that flows into the radially outermost end of scope with respect to the combustion gas of otch glory hole.Its result presents around the gas quantity to the outer end of otch glory hole and to increase, and prolongs burning thereby improved flame.
In addition, if below the part of the formation otch glory hole of the upper wall portions of main burner top cap, be formed with the depressed part above being recessed to, because the thickness attenuation of the upper wall portions of the part of formation otch glory hole, so the aeration resistance of otch glory hole reduces, thereby increased from the gas quantity of that part of otch glory hole ejection, improved flame and prolonged burning.
