專利文獻1 日本專利公開公報特開2004-93056號公報Patent Document 1 Japanese Patent Laid-Open Publication No. 2004-93056
然而，由於習知閉塞板係載置於頂板上之構造，因此，相對於瓦斯燃燒器或頂板亦容易產生錯位，不僅閉塞狀態不足，外觀上亦不理想。又，在清掃等之保養時可容易地自頂板輕易地卸下，另一方面，在燃燒器本體之清掃等之保養時燃燒器用開口會開放，因此，會有異物掉落、侵入爐具本體內部之虞。However, since the conventional occlusion plate is placed on the top plate, misalignment is likely to occur with respect to the gas burner or the top plate, and not only the occlusion state is insufficient, but also the appearance is not satisfactory. In addition, it is easy to remove from the top plate during maintenance such as cleaning, and the burner opening is opened during maintenance such as cleaning of the burner body. Therefore, foreign matter may fall and invade the stove. The inside of the body.
有鑑於前述情形，本發明之目的係提供一種瓦斯爐，且該瓦斯爐可確實地閉塞混合管之下游端部與頂板之燃燒器用開口間，並可取得良好之外觀且生產性亦高。In view of the foregoing, it is an object of the present invention to provide a gas burner which can positively occlude between the downstream end of the mixing tube and the burner opening of the top plate, and which can achieve a good appearance and high productivity.
本發明係一種瓦斯爐，且該瓦斯爐包含有：爐具本體；頂板，係覆蓋該爐具本體之上面者；及瓦斯燃燒器，係透過業已形成於該頂板之燃燒器用開口，使一部分露出者；又，前述瓦斯燃燒器包含有：混合管，係使下游端部面對前述燃燒器用開口者；及燃燒器本體，係於前述頂板上露出者；並且，使突設於燃燒器本體之下面中央部之筒狀混合氣流入部嵌合於混合管之下游端，並將來自混合管之混合氣供給至燃燒器本體，又，將閉塞板設置成與前述燃燒器本體呈同心地連結於前述混合管，且前述閉塞板係遍及全周地將形成於前述混合管之下游端部之外周壁與燃燒器用開口之周緣間的環狀間隙閉塞。The present invention is a gas furnace, and the gas furnace comprises: a stove body; a top plate covering the upper portion of the stove body; and a gas burner for exposing a portion through an opening of the burner which has been formed on the top plate Further, the gas burner includes: a mixing tube that faces the downstream end of the burner; and a burner body that is exposed on the top plate; and that protrudes from the burner body The tubular mixed airflow inlet portion at the center portion is fitted to the downstream end of the mixing pipe, and the mixed gas from the mixing pipe is supplied to the burner body, and the blocking plate is disposed to be concentrically coupled to the burner body. The mixing tube is configured such that the blocking plate is closed over the entire circumference by an annular gap formed between the outer peripheral wall of the downstream end portion of the mixing tube and the periphery of the burner opening.
若藉由本發明，則將閉塞板連結於混合管，藉此，即使自混合管卸下燃燒器本體，閉塞板亦可維持混合管與燃燒器用開口間之閉塞狀態，因此，可確實地防止在燃燒器本體之清掃等之保養時，異物透過燃燒器用開口而掉落、侵入爐具本體內部。According to the present invention, the closing plate is coupled to the mixing tube, whereby the closing plate can maintain the closed state between the mixing tube and the burner opening even if the burner body is removed from the mixing tube, so that it can be reliably prevented. When the burner body is cleaned or the like, the foreign matter is dropped through the opening of the burner and is invaded into the inside of the furnace body.
又，藉由將閉塞板連結於混合管，即使組裝於混合管之燃燒器本體與頂板之燃燒器用開口產生軸心偏離，閉塞板亦可確實地閉塞燃燒器用開口，並可防止異物或溢出的湯汁侵入爐具本體內部。又，藉由使閉塞板閉塞燃燒器用開口，爐具本體與燃燒器用開口之錯位不會露出，並可防止外觀之降低。再者，無需如習知般用以沿著頂板之燃燒器用開口之內周緣固定閉塞板之機構，且零件數亦少，同時由於組裝容易，因此生產性亦高。Further, by connecting the blocking plate to the mixing pipe, even if the burner body assembled to the mixing pipe and the burner opening of the top plate are axially offset, the closing plate can surely close the burner opening and prevent foreign matter or overflow. The soup invades the inside of the body of the stove. Further, by closing the opening of the burner by the closing plate, the misalignment of the opening of the cooker body and the burner is not exposed, and the appearance can be prevented from being lowered. Further, there is no need to use a mechanism for fixing the occlusion plate along the inner periphery of the burner opening of the top plate as is conventionally known, and the number of parts is small, and the productivity is also high because assembly is easy.
又，於本發明中，前述閉塞板宜形成為自其外周朝混合管之下游端部逐漸地增加高度之形狀。藉此，當沿著頂板之上面流動的燃燒用二次空氣朝向燃燒器本體時，會藉由閉塞板朝上升方向導引，故，可將二次空氣順利地供給至燃燒中的燃燒器本體，並可取得瓦斯燃燒器良好之燃燒。又，溢出的湯汁不會積存於閉塞板上，並可防止因髒污附著於閉塞板所造成的外觀之降低，且由於髒污之擦拭作業亦容易，因此清掃等之保養性亦佳。Further, in the invention, it is preferable that the occlusive plate is formed in a shape which gradually increases in height from the outer periphery toward the downstream end portion of the mixing tube. Thereby, when the secondary air for combustion flowing along the upper surface of the top plate faces the burner body, it is guided in the ascending direction by the blocking plate, so that the secondary air can be smoothly supplied to the burner body in combustion. And can get good combustion of gas burner. Further, the overflowed soup is not stored on the occlusion plate, and the appearance of the squeegee adhered to the occlusion plate is prevented from being lowered, and the wiping operation due to dirt is also easy, so that the maintenance property such as cleaning is also good.
又，於本發明中，宜於自前述頂板露出之燃燒器本體之周圍設置火架，且該火架係定位成其下部內側面嵌合於前述閉塞板之外周部。由於火架係構成藉由閉塞板定位之狀態，因此，可使燃燒器本體之軸心與火架之軸心一致，並可將相對於燃燒器本體之火架之位置維持於良好之狀態。Further, in the invention, it is preferable that a fire holder is provided around the burner body exposed from the top plate, and the fire frame is positioned such that a lower inner side surface thereof is fitted to an outer peripheral portion of the blocking plate. Since the fire frame is in a state of being positioned by the blocking plate, the axis of the burner body can be aligned with the axis of the fire frame, and the position of the fire frame relative to the burner body can be maintained in a good state.
再者，前述火架宜載置於前述閉塞板。藉此，不會因爐具本體之應變或頂板之應變等而受到業已支持於爐具本體之瓦斯燃燒器與頂板之相對高度之變形之影響，並可將相對於燃燒器本體之火架之高度維持一定。Furthermore, the fire frame is preferably placed on the occlusion plate. Thereby, the deformation of the relative height of the gas burner and the top plate which has been supported by the main body of the furnace is not affected by the strain of the main body or the strain of the top plate, etc., and the flame frame relative to the burner body can be The height is maintained at a certain level.
又，於本發明中，前述閉塞板宜為其外周部下面透過襯墊而抵接於沿著燃燒器用開口周緣之頂板上面，且前述襯墊係設置成當前述閉塞板位於非抵接狀態時，可相對於前述頂板而自由移動。Further, in the present invention, it is preferable that the occluding plate has a lower outer peripheral portion penetrating the spacer against the top surface of the top plate along the periphery of the burner opening, and the spacer is disposed when the occluding plate is in a non-contact state. It can move freely with respect to the aforementioned top plate.
一般而言，瓦斯燃燒器係安裝支持於爐具本體，然而，由於瓦斯燃燒器於爐具本體之安裝誤差，會有燃燒器本體相對於頂板之燃燒器用開口而發生軸心偏離之情形。此時，當襯墊嵌合、安裝於燃燒器用開口之內周緣時，相對於襯墊，閉塞板會發生錯位。故，不僅無法藉由襯墊充分地封裝閉塞板與燃燒器用開口間，且襯墊之一部分係自閉塞板露出而有外觀降低之虞。In general, the gas burner is mounted to support the body of the stove. However, due to the installation error of the gas burner in the body of the stove, there is a case where the burner body is axially offset with respect to the burner opening of the top plate. At this time, when the gasket is fitted and attached to the inner periphery of the burner opening, the blocking plate is displaced with respect to the gasket. Therefore, it is not only impossible to sufficiently enclose the gap between the closing plate and the burner opening by the gasket, and one of the gaskets is exposed from the closing plate to have a reduced appearance.
故，於本發明中，藉由將閉塞板位於非抵接狀態時的襯墊作成可自由移動，即使產生燃燒器用開口與燃燒器本體之軸心偏離，襯墊亦會按照其偏離尺寸而移動，因此，不會受到軸心偏離之影響，並可確實地密封閉塞板與燃燒器用開口間，且亦可防止外觀之降低。Therefore, in the present invention, the spacer is freely movable by the spacer in the non-contact state, and even if the burner opening is deviated from the axis of the burner body, the spacer moves according to the deviation dimension. Therefore, it is not affected by the deviation of the axial center, and the sealing plate and the opening for the burner can be surely sealed, and the appearance can be prevented from being lowered.

第2圖係本實施形態之瓦斯爐之主要部分截面圖。Fig. 2 is a cross-sectional view showing the main part of the gas burner of the present embodiment.
第3圖係顯示本實施形態之瓦斯爐所具有的瓦斯燃燒器之立體圖。Fig. 3 is a perspective view showing a gas burner included in the gas furnace of the present embodiment.
以下，參照圖式，說明本發明之實施形態。如第1及2圖中顯示主要部分，本實施形態之瓦斯爐係具有瓦斯燃燒器1；及設置於瓦斯燃燒器1周圍的火架2。Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in the first and second figures, the gas furnace of the present embodiment has a gas burner 1 and a flame frame 2 provided around the gas burner 1.
瓦斯燃燒器1包含有：燃燒器本體4，係於構成瓦斯爐之一部分的頂板3上露出者；及混合管8，係於構成瓦斯爐之另一部分的爐具本體5之內部，透過台座部7連結固定於底板6者。混合管8之下游端部8a係朝上方開口。The gas burner 1 comprises: a burner body 4 which is exposed on a top plate 3 constituting a part of the gas furnace; and a mixing pipe 8 which is inside the furnace body 5 constituting another part of the gas furnace and passes through the pedestal portion 7 is fixed to the bottom plate 6. The downstream end portion 8a of the mixing tube 8 is opened upward.
如第2圖所示，頂板3係設置成覆蓋爐具本體5之上面，並藉由頂板本體10及閉塞板11所構成，且前述頂板本體10係形成直徑大於燃燒器本體4之燃燒器用開口9，前述閉塞板11係覆蓋頂板本體10之燃燒器用開口9。頂板本體10係藉由金屬板或玻璃板平坦地形成，閉塞板11則藉由金屬板來形成。As shown in Fig. 2, the top plate 3 is disposed to cover the upper surface of the stove body 5, and is constituted by the top plate body 10 and the blocking plate 11, and the top plate body 10 is formed with a burner opening having a diameter larger than that of the burner body 4. 9. The occlusion plate 11 covers the burner opening 9 of the top plate body 10. The top plate body 10 is formed flat by a metal plate or a glass plate, and the blocking plate 11 is formed by a metal plate.
閉塞板11係於中央部開設可插裝混合管8之下游端部8a之插裝孔12。又，閉塞板11係形成為自其外周朝混合管8之下游端部8a透過落差而逐漸地增加高度之形狀。The occlusion plate 11 is provided with an insertion hole 12 at the center portion of the downstream end portion 8a of the insertable mixing tube 8. Further, the occlusion plate 11 is formed in a shape in which the height is gradually increased from the outer periphery toward the downstream end portion 8a of the mixing tube 8 by the drop.
藉此，於調理時溢出的湯汁不會積存而可流向外周，並可防止因髒污附著所造成的外觀之降低，且由於髒污之擦拭作業亦容易，因此清掃等之保養性亦佳。Thereby, the soup overflowing during conditioning does not accumulate and can flow to the outer circumference, and the appearance of the dirt due to the adhesion of dirt can be prevented from being lowered, and the wiping operation due to dirt is also easy, so the maintenance property such as cleaning is also good. .
閉塞板11雖構成頂板3之一部分，但並未與頂板3連結，且藉由螺絲構件13，連結固定於瓦斯燃燒器1之混合管8。閉塞板11係形成為在將混合管8之下游端部8a插裝於插裝孔12時，構成與燃燒器本體4呈同心之圓形。The occlusion plate 11 constitutes a part of the top plate 3, but is not coupled to the top plate 3, and is coupled and fixed to the mixing tube 8 of the gas burner 1 by the screw member 13. The occlusion plate 11 is formed to have a circular shape concentric with the burner body 4 when the downstream end portion 8a of the mixing tube 8 is inserted into the insertion hole 12.
閉塞板11之外周部下面係透過襯墊14，抵接於依循著燃燒器用開口9周緣之頂板本體10之上面。襯墊14係藉由以下所構成，即：密封部14a，係密接於頂板本體10之上面者；凸緣部14b，係朝該密封部14a之外周伸出，並抵接閉塞板11之外周緣者；及垂下部14c，係自密封部14a之內周朝下方延伸者。襯墊14之垂下部14c之外徑會稍微小於燃燒器用開口9之內徑，且於閉塞板11與密封部14a位於非抵接狀態時(即，閉塞板11之組裝前之狀態)，構成可相對於前述頂板本體10而自由移動。The outer peripheral portion of the occluding plate 11 is passed through the spacer 14 to abut against the upper surface of the top plate body 10 which follows the periphery of the opening 9 for the burner. The gasket 14 is configured such that the sealing portion 14a is in close contact with the upper surface of the top plate body 10; the flange portion 14b projects toward the outer periphery of the sealing portion 14a and abuts against the outer periphery of the blocking plate 11 The lower portion 14c is extended downward from the inner circumference of the sealing portion 14a. The outer diameter of the hanging portion 14c of the gasket 14 is slightly smaller than the inner diameter of the burner opening 9, and when the blocking plate 11 and the sealing portion 14a are in a non-contact state (that is, the state before the assembly of the blocking plate 11), It is free to move relative to the aforementioned top plate body 10.
藉此，舉例言之，即使因混合管8於爐具本體5之底部6的安裝位置之誤差，產生組裝於混合管8之燃燒器本體4與頂板3之燃燒器用開口9之軸心偏離，燃燒器用開口9之內周緣亦藉由閉塞板11之外周部來隱藏，因此，可防止外觀之降低。又，前述襯墊14係其垂下部14c之外徑稍微小於燃燒器用開口9之內徑，並構成可相對於頂板本體10而自由移動。故，即使連結於混合管8之閉塞板11與燃燒器用開口9產生軸心偏離，襯墊14亦會按照其偏離尺寸而移動，並可確實地密封閉塞板11之外周部下面與依循著燃燒器用開口9周緣之頂板本體10之上面間。Thereby, for example, even if the mixing tube 8 is at the mounting position of the bottom portion 6 of the oven body 5, the axial center deviation of the burner opening 4 assembled to the mixing tube 8 and the burner opening 9 of the top plate 3 is generated. The inner circumference of the burner opening 9 is also hidden by the outer peripheral portion of the closing plate 11, so that the appearance can be prevented from being lowered. Further, the spacer 14 has an outer diameter of the hanging portion 14c which is slightly smaller than the inner diameter of the burner opening 9, and is configured to be freely movable with respect to the top plate body 10. Therefore, even if the occlusion plate 11 connected to the mixing tube 8 and the burner opening 9 are axially offset, the spacer 14 is moved according to its offset size, and the outer periphery of the occluding plate 11 can be surely sealed and burned. The upper surface of the top body 10 of the peripheral edge of the opening 9 is used.
火架2係由環狀之火架框2a及5個火架爪2b所構成，且該火架爪2b係於該火架框2a之周方向隔著預定間隔而固定支持。火架框2a係嵌合於業已形成於閉塞板11外周部之落差，並於業經定位之狀態下載置於閉塞板11上。The fire frame 2 is composed of an annular fire frame 2a and five fire frame claws 2b, and the fire frame claws 2b are fixedly supported at predetermined intervals in the circumferential direction of the frame frame 2a. The fire frame 2a is fitted to the gap which has been formed on the outer peripheral portion of the blocking plate 11, and is placed on the blocking plate 11 in a state of being positioned.
即，火架2係構成透過閉塞板11而載置於混合管8之狀態。藉此，可使組裝於混合管8之燃燒器本體4之軸心與火架2之軸心一致。再者，即使於爐具本體5發生應變等而改變頂板本體10與底部6之距離，火架2亦藉由載置於業已連結於混合管8之閉塞板11，而可將燃燒器本體4與載置於火架2上之鍋底之間隔距離維持一定。In other words, the fire frame 2 is in a state of being placed on the mixing tube 8 through the blocking plate 11. Thereby, the axis of the burner body 4 assembled to the mixing pipe 8 can be aligned with the axis of the fire frame 2. Furthermore, even if the furnace body 5 is strained or the like and the distance between the top plate body 10 and the bottom portion 6 is changed, the fire frame 2 can be placed on the burner plate 4 by being placed on the occlusion plate 11 which has been coupled to the mixing tube 8. The distance from the bottom of the pot placed on the fire frame 2 is kept constant.
另，雖未圖示，然而，即使火架係載置於頂板本體10上之形狀者，藉由使環狀之火架框之內周面嵌合於閉塞板11之外周部，而可使燃燒器本體之軸心與火架之軸心一致。又，舉例言之，在各火架爪之下端緣係構成載置面之火架時，亦可將各火架爪之下部內側面嵌合於閉塞板11之外周部。Further, although not shown, even if the shape of the flame frame is placed on the top plate main body 10, the inner circumferential surface of the annular flame frame can be fitted to the outer peripheral portion of the closing plate 11, The axis of the burner body coincides with the axis of the fire frame. Further, for example, when the lower edge of each of the frame claws constitutes the frame of the mounting surface, the inner side surface of the lower portion of each of the frame claws may be fitted to the outer peripheral portion of the blocking plate 11.
燃燒器本體4係具有母燃燒器部15及子燃燒器部16而構成所謂子母燃燒器。如第3圖所示，混合管8包含有：母燃燒器用混合管部17，係將混合氣體供給至母燃燒器部15者；及子燃燒器用混合管部18，係將混合氣體供給至子燃燒器部16者。The burner body 4 has a mother burner portion 15 and a sub-burner portion 16 to constitute a so-called mother burner. As shown in Fig. 3, the mixing pipe 8 includes a mixed burner portion 17 for the mother burner, and a mixed gas supply unit 15 for the mixed gas, and a mixed gas portion 18 for the sub-combustor to supply the mixed gas to the sub-combustion unit. The burner unit 16 is.
如第2圖所示，混合管8之下游端部8a係於母燃燒器用混合管部17之內側收納子燃燒器用混合管部18而作成二重管結構。As shown in Fig. 2, the downstream end portion 8a of the mixing tube 8 is housed in the mixing tube portion 18 for the sub-combustor in the inside of the mixing tube portion 17 for the mother burner to form a double tube structure.
如第1及2圖所示，燃燒器本體4係藉由燃燒器主體19及一對燃燒器頭(母燃燒器頭20及子燃燒器頭21)所構成。燃燒器主體19係於其外側形成母燃燒器部15之分布室22，並於內側形成子燃燒器部16之分布室23。藉由於母燃燒器部15之分布室22上載置母燃燒器頭20，於母燃燒器部15之外周形成複數母燃燒器焰孔24，且藉由於子燃燒器部16之分布室23上載置子燃燒器頭21，於子燃燒器部16之外周形成複數子燃燒器焰孔25。As shown in Figs. 1 and 2, the burner body 4 is composed of a burner body 19 and a pair of burner heads (a mother burner head 20 and a sub-burner head 21). The burner main body 19 is formed on the outer side thereof to form the distribution chamber 22 of the mother burner portion 15, and the distribution chamber 23 of the sub-burner portion 16 is formed inside. By placing the mother burner head 20 on the distribution chamber 22 of the mother burner portion 15, a plurality of mother burner flame holes 24 are formed on the outer circumference of the mother burner portion 15, and are placed on the distribution chamber 23 of the sub-burner portion 16 The sub-burner head 21 forms a plurality of sub-combustor flame holes 25 outside the sub-combustor portion 16.
又，於燃燒器主體19之下面中央部，對應於混合管8之下游端部8a而設置筒狀之混合氣流入部26。如第2圖所示，混合氣流入部26係藉由位於外側之母燃燒器用通路27及其內側之子燃燒器用通路28所構成。若混合氣流入部26嵌合於混合管8之下游端部8a，則母燃燒器用通路27係與母燃燒器用混合管部17連通，同時子燃燒器用通路28係與子燃燒器用混合管部18連通。另，混合氣流入部26係嵌合於混合管8之下游端部8a且可自由裝卸，並構成在清掃等之保養時可輕易地自混合管8卸下燃燒器本體4。Further, a cylindrical mixed airflow entering portion 26 is provided at a central portion of the lower surface of the burner main body 19 corresponding to the downstream end portion 8a of the mixing pipe 8. As shown in Fig. 2, the mixed airflow entering portion 26 is constituted by the outer mother burner passage 27 and the sub-combustor passage 28 on the inner side. When the mixed airflow inlet portion 26 is fitted to the downstream end portion 8a of the mixing pipe 8, the mother burner passage 27 communicates with the mother burner mixing pipe portion 17, and the sub-combustor passage 28 communicates with the sub-combustor mixing pipe portion 18. . Further, the mixed airflow inlet portion 26 is fitted to the downstream end portion 8a of the mixing pipe 8, and is detachably attachable, and is configured to easily detach the burner body 4 from the mixing pipe 8 during maintenance such as cleaning.
又，如第2圖所示，混合氣流入部26係配置於燃燒器主體19之子燃燒器部16之下部位置，因此，如第1及2圖所示，母燃燒器用通路27係藉由自子燃燒器部16側呈放射狀延伸之聯絡管部29，與母燃燒器部15之分布室22連通。Further, as shown in Fig. 2, the mixed airflow entering portion 26 is disposed at a position below the sub-burner portion 16 of the combustor body 19. Therefore, as shown in Figs. 1 and 2, the mother burner passage 27 is controlled by the subroutine. The contact portion 29 that radially extends on the side of the burner portion 16 communicates with the distribution chamber 22 of the mother burner portion 15.
又，未圖示之氣體噴嘴係面對前述混合管8之母燃燒器用混合管部17與子燃燒器用混合管部18各自之上游端。若自氣體噴嘴噴出燃料氣，則隨著燃料氣之噴出，吸引一次空氣，並生成混合氣體。Further, a gas nozzle (not shown) faces the upstream end of each of the mixing tube portion 17 for the mother burner and the mixing tube portion 18 for the sub-combustor 8 of the mixing tube 8. When the fuel gas is ejected from the gas nozzle, the primary air is sucked as the fuel gas is ejected, and a mixed gas is generated.
如第2圖所示，於母燃燒器頭20之一部分形成點火靶30。點火靶30係與業已透過支持構件31支持於混合管8之點火塞32之前端相對，並接受點火塞32之放電而對母燃燒器部15點火。點火塞32係貫通閉塞板11而朝上方延伸。另，於第1圖中以符號33所示者係檢測子燃燒器部16之著火的熱電偶。雖未圖示，然而，熱電偶33亦與點火塞32相同地支持於混合管8，並貫通閉塞板11而朝上方延伸。As shown in Fig. 2, an ignition target 30 is formed in a portion of the mother burner head 20. The ignition target 30 is opposed to the front end of the ignition plug 32 of the mixing tube 8 through the support member 31, and receives the discharge of the ignition plug 32 to ignite the mother burner portion 15. The ignition plug 32 extends through the blocking plate 11 and upward. Further, in the first drawing, the thermocouple of the sub-combustor portion 16 is detected by the symbol 33. Although not shown, the thermocouple 33 is also supported by the mixing tube 8 in the same manner as the ignition plug 32, and extends upward through the blocking plate 11.
如第1及3圖所示，藉由母燃燒器部15所形成的火焰係透過業已形成於母燃燒器頭20之移火用狹縫20a而移火至子燃燒器部16，藉此，子燃燒器部16會點火。藉由子燃燒器部16所形成的火焰係自前述聯絡管部29間之空隙供給二次空氣。此時，閉塞板11係形成為自其外周朝混合管8之下游端部8a透過落差而逐漸地增加高度之形狀，藉此，形成自頂板之上面朝燃燒器本體4上升之二次空氣流。故，不僅是母燃燒器部15，於子燃燒器部16亦可供給充分量之二次空氣，並可取得良好之燃燒狀態。As shown in the first and third figures, the flame formed by the mother burner portion 15 passes through the misalignment slit 20a which has been formed in the mother burner head 20, and is transferred to the sub-combustor portion 16, whereby The sub-burner portion 16 will ignite. The flame formed by the sub-burner unit 16 supplies secondary air from the gap between the communication pipe portions 29. At this time, the occlusion plate 11 is formed to gradually increase the height from the outer periphery toward the downstream end portion 8a of the mixing tube 8 by the drop, thereby forming a secondary air flow rising from the upper surface of the top plate toward the burner body 4. . Therefore, not only the mother burner portion 15, but also a sufficient amount of secondary air can be supplied to the sub-combustor portion 16, and a good combustion state can be obtained.
另，於本實施形態中，顯示瓦斯燃燒器1係具有母燃燒器部15及子燃燒器部16者，然而，雖未圖示，但只要是混合管嵌合於燃燒器本體之中央部之構造的瓦斯燃燒器，則即使是具有單一燃燒器部之瓦斯燃燒器，亦可適當地採用本發明。Further, in the present embodiment, the gas burner 1 is provided with the mother burner portion 15 and the sub-burner portion 16. However, although not shown, the mixing tube is fitted to the central portion of the burner body. The gas burner of the configuration can be suitably used in the present invention even in the case of a gas burner having a single burner portion.
