Description
本發明涉及一種爐灶用燃燒器，具備被支撑在固定於爐灶本體的燃燒器支架上的燃燒器主體。The present invention relates to a burner for a cooker comprising a burner body supported on a burner holder fixed to a cooktop body.
以往，作為這種爐灶用燃燒器已知有如下結構：在燃燒器主體的下表面中央部垂直設置筒狀的喉部，並且將喉部從上方插入到燃燒器支架的支撑筒部，使得燃燒器主體的下表面座落在支撑筒部的上端，其中，該燃燒器支架具備固定於爐灶本體的基座部和設置於基座部上方的支撑筒部。再者，在基座部設置向喉部的下端開口噴出燃氣的噴氣嘴，向燃燒器主體內供給從喉部的下端開口吸入的一次空氣和燃氣的混和氣(參照例如專利文獻1)。Conventionally, as such a burner for a cooktop, a tubular throat is vertically disposed at a central portion of a lower surface of a burner body, and a throat is inserted from above into a support cylinder portion of a burner holder to cause combustion. The lower surface of the main body is seated at an upper end of the support cylinder portion, and the burner bracket includes a base portion fixed to the cooker body and a support cylinder portion disposed above the base portion. In addition, a gas nozzle that discharges gas to the lower end opening of the throat is provided in the base portion, and a mixed gas of primary air and gas that is taken in from the lower end opening of the throat is supplied into the burner main body (see, for example, Patent Document 1) .
在此，為了使燃燒器主體不發生搖動而穩定地被支撑在燃燒器支架上，需要將喉部的外周面以保留相當於插入餘隙(可插入喉部所需的最小限度的餘隙)的間隙的方式嵌合在支撑筒部的內周面上，並且，需要確保喉部對於支撑筒部的嵌合部分的上端至下端的長度盡可能較長。但是，有時若產生大量的溢出湯汁，則溢出湯汁到達支撑筒部，進入喉部的外周面與支撑筒部的內周面之間的間隙的溢出湯汁會使喉部固著在支撑筒部上。並且，如果喉部對於支撑筒部的嵌合部分的長度較長，溢出湯汁所產生的固著力變強，有時不能取下燃燒器主體。Here, in order to stably support the burner body on the burner holder without shaking, it is necessary to retain the outer peripheral surface of the throat to be equivalent to the insertion clearance (the minimum clearance required for insertion into the throat) The gap is fitted in the inner peripheral surface of the support cylinder portion, and it is necessary to ensure that the length of the throat from the upper end to the lower end of the fitting portion of the support cylinder portion is as long as possible. However, if a large amount of overflowing broth is generated, the overflowing soup reaches the support tube portion, and the overflowing soup which enters the gap between the outer peripheral surface of the throat and the inner peripheral surface of the support tube portion fixes the throat. Support the tube. Further, if the length of the throat portion to the fitting portion of the support cylinder portion is long, the fixing force generated by the overflow of the soup becomes strong, and sometimes the burner body cannot be removed.
另外，以往已知有如下結構：在將垂直設置於燃燒器主體上的筒部外嵌合到混合管的朝上方彎曲的下游端部上的爐灶用燃燒器中，將混合管的下游端部的外周面和筒部的內周面形成為朝著下方直徑擴大的圓錐面，並且，在筒部的內周面的上部和下部的 中間形成了朝徑向外側凹入的凹面部(參照例如專利文獻2)。根據該結構，燃燒器主體的安裝作業變得容易，筒部對於混合管下游端部的嵌合部分的長度縮短相當於凹面部的尺寸，使得溢出湯汁所產生的固著力變弱。Further, it has been conventionally known to have a structure in which a downstream end portion of a mixing tube is fitted in a burner for a stove that is fitted to a downstream end portion of a mixing tube that is vertically disposed on a burner main body. The outer peripheral surface and the inner peripheral surface of the tubular portion are formed as a conical surface that expands toward the lower diameter, and the upper and lower portions of the inner peripheral surface of the tubular portion A concave surface that is recessed outward in the radial direction is formed in the middle (see, for example, Patent Document 2). According to this configuration, the attachment work of the burner main body becomes easy, and the length of the fitting portion of the tubular portion with respect to the downstream end portion of the mixing tube is shortened to correspond to the size of the concave surface portion, so that the fixing force generated by the overflow of the soup is weakened.
可以考慮將該技術應用於專利文獻1記載的燃燒器，將喉部的外周面和支撑筒部的內周面形成為朝著下方直徑减小的圓錐面，並且，在支撑筒部的內周面的上部和下部的中間形成向徑向外側凹入的凹面部，使溢出湯汁所產生的固著力變弱。This technique can be applied to the burner described in Patent Document 1, and the outer peripheral surface of the throat and the inner peripheral surface of the support tubular portion are formed into a conical surface whose diameter decreases toward the lower side, and the inner circumference of the support cylinder portion A concave portion that is recessed outward in the radial direction is formed in the middle of the upper portion and the lower portion of the surface, and the fixing force generated by the overflow of the soup is weakened.
但是，利用這樣的結構，會產生以下問題。亦即，專利文獻1記載的燃燒器中，通過使燃燒器主體的下表面座落於支撑筒部的上端來决定燃燒器主體的高度，因此，隨著燃燒器主體的下表面或支撑筒部的上端的加工公差，燃燒器主體的高度發生變化。並且，在圓錐面上形成的喉部的外周面與支撑筒部的內周面之間的間隙量，會隨著燃燒器主體的高度變化而變化，有時會影響燃燒器主體的穩定性。此外，凹面部需要使用在徑向伸縮自如的特殊工具進行加工，有時會發生加工變複雜的問題。However, with such a structure, the following problems occur. In the burner described in Patent Document 1, the height of the burner body is determined by seating the lower surface of the burner body at the upper end of the support cylinder portion, and therefore, along with the lower surface of the burner body or the support cylinder portion The machining tolerance of the upper end changes the height of the burner body. Further, the amount of the gap between the outer peripheral surface of the throat formed on the conical surface and the inner peripheral surface of the support tubular portion changes depending on the height of the burner body, which may affect the stability of the burner body. In addition, the concave surface needs to be processed using a special tool that is radially expandable and contractible, and sometimes the processing becomes complicated.

本發明鑒於以上問題點而做出，其目的在於提供一種爐灶用燃燒器，不影響燃燒器主體的穩定性，可减弱溢出湯汁引起的喉部對於支撑筒部的固著力，而且，加工也容易。The present invention has been made in view of the above problems, and an object thereof is to provide a burner for a stove which does not affect the stability of the burner body, and can reduce the fixing force of the throat to the support cylinder caused by the overflow of the soup, and the processing is also easily.
本發明提供的爐灶用燃燒器，具備被支撑在固定於爐灶本體的燃燒器支架上的燃燒器主體，其中，燃燒器主體具備在其下表面中央部垂直設置的筒狀的喉部，燃燒器支架具備固定於爐灶本體上的基座部和設於基座部上方的支撑筒部，將喉部從上方插入支撑筒部，使燃燒器主體的下表面坐落於支撑筒部的上端，並且，在基座部設置向喉部的下端開口噴出燃氣的噴氣嘴，向燃燒器主體內供給從喉部的下端開口吸入的一次空氣和燃氣的混和氣。為了解决上述課題，其特徵是具備如下所述的結構。A burner for a cooktop provided by the present invention includes a burner body supported on a burner holder fixed to a cooker body, wherein the burner body is provided with a cylindrical throat vertically disposed at a central portion of a lower surface thereof, and the burner The bracket has a base portion fixed to the cooker body and a support tubular portion disposed above the base portion, and the throat portion is inserted into the support tubular portion from above, so that the lower surface of the burner body is seated at the upper end of the support tubular portion, and An air nozzle that discharges gas to the lower end opening of the throat is provided in the base portion, and a mixed air of primary air and gas sucked from the lower end opening of the throat is supplied into the burner main body. In order to solve the above problems, it is characterized in that it has the following structure.
亦即，本發明是，在喉部的外周面形成以下各部分：圓筒狀的上部嵌合突起部；圓筒狀的下部嵌合突起部，位於從上部嵌合突起部向下方離開的部分，其直徑小於上部嵌合突起部；以及縮徑部，位於上部嵌合突起部與下部嵌合突起部之間，具有朝著下方直徑减小的圓錐體狀或直徑小於上部嵌合突起部的圓筒狀；在支撑筒部的內周面形成以下各部分：上部嵌合凹部，為圓筒狀，使上部嵌合突起部以保留相當於插入餘隙的間隙的方式嵌合；下部嵌合凹部，位於從上部嵌合凹部向下方離開的部分，具有直徑小於上部嵌合凹部的圓筒狀，使下部嵌合突起部以保留相當於插入餘隙的間隙的方式嵌合；以及導引部，位於上部嵌合凹部與下部嵌合凹部之間，具有朝著下方直徑减小的圓錐體形狀；上部嵌合凹部的上下方向長度被設定成：在燃燒器主體的下表面坐落於支撑筒部的上端的狀態下，上部嵌合凹部的下端比上部嵌合突起部的下端更位於下方。In other words, in the present invention, the outer peripheral surface of the throat is formed with a cylindrical upper fitting projection; and the cylindrical lower fitting projection is located downward from the upper fitting projection. The diameter is smaller than the upper fitting protrusion portion; and the reduced diameter portion is located between the upper fitting protrusion portion and the lower fitting protruding portion, and has a conical shape having a diameter decreasing toward the lower side or a diameter smaller than the upper fitting protruding portion. a cylindrical shape is formed on the inner circumferential surface of the support tubular portion: the upper fitting concave portion has a cylindrical shape, and the upper fitting projection portion is fitted so as to retain a gap corresponding to the insertion clearance; the lower fitting portion The recessed portion is located at a portion that is downwardly separated from the upper fitting recessed portion, and has a cylindrical shape having a smaller diameter than the upper fitting recessed portion, and the lower fitting protruding portion is fitted so as to retain a gap corresponding to the insertion clearance; and the guide portion Between the upper fitting recess and the lower fitting recess, having a shape of a cone having a diameter decreasing toward the lower side; the length of the upper fitting recess being set in the up-and-down direction is set to be located on the lower surface of the burner body Lower support upper cylindrical portion of the state, the lower end of the upper portion of the fitting recessed portion lower than the upper fitting projection portion is positioned further below.
根據本發明，由於上部與下部的嵌合突起部和嵌合凹部都形成為圓筒狀，即使燃燒器主體的下表面或支撑筒部的上端的加工公差引起燃燒器主體的高度變化，各嵌合突起部與各嵌合凹部之間的間隙量也不會變化，能夠保持插入喉部所需的最小限度的插 入餘隙。因此，燃燒器主體能夠不搖動而穩定地被支撑在燃燒器支架上。According to the invention, since the fitting projections and the fitting recesses of the upper and lower portions are both formed in a cylindrical shape, even if the machining tolerance of the lower surface of the burner main body or the upper end of the support cylinder portion causes a change in the height of the burner main body, each of the cavities The amount of the gap between the protruding portion and each of the fitting recesses does not change, and the minimum insertion required to insert the throat can be maintained. Into the gap. Therefore, the burner body can be stably supported on the burner holder without shaking.
此外，由於在比上部嵌合突起部的下端更位於下方的上部嵌合凹部部分與縮徑部之間確保較寬的間隙，因此，在縮徑部不發生溢出湯汁引起的喉部對於支撑筒部的固著。因此，溢出湯汁引起的固著力變弱，能夠防止燃燒器主體不能取下。並且，不需要在支撑筒部內周面的上下方向中間部為弱化固著力而形成向徑向外側凹入的凹面部，加工變得容易。Further, since a wide gap is secured between the upper fitting recess portion and the reduced diameter portion which are located below the lower end of the upper fitting projection, the throat is not supported by the overflowing portion in the reduced diameter portion. Fixation of the barrel. Therefore, the fixing force caused by the overflow of the soup becomes weak, and the burner body can be prevented from being removed. Further, it is not necessary to form a concave surface that is recessed outward in the radial direction by weakening the fixing force in the intermediate portion in the vertical direction of the inner circumferential surface of the support cylinder portion, and the processing becomes easy.
此外，將喉部插入支撑筒部時，通過圓錐體狀的導引部進行引導使喉部與支撑筒部成同心，下部嵌合突起部和上部嵌合突起部順利地嵌合在下部嵌合凹部及上部嵌合凹部。因此，燃燒器主體的安裝作業變得容易。Further, when the throat portion is inserted into the support tubular portion, the throat portion is guided by the conical guide portion so that the throat portion is concentric with the support cylinder portion, and the lower fitting projection portion and the upper fitting projection portion are smoothly fitted to the lower fitting portion. The recess and the upper fitting recess. Therefore, the mounting work of the burner body becomes easy.
此外，在本發明中，優選在下部嵌合凹部和下部嵌合突起部中的至少一個上，形成沿上下方向延伸的槽部。由此，能够通過槽部將溢出湯汁排出到支撑筒部的下方，提高防止溢出湯汁引起的喉部對於支撑筒部固著的功能。Further, in the invention, it is preferable that a groove portion extending in the vertical direction is formed on at least one of the lower fitting recess and the lower fitting projection. Thereby, the overflow soup can be discharged to the lower side of the support tube portion by the groove portion, and the function of preventing the throat from sticking to the support tube portion due to the overflow of the soup can be improved.

Further, a recessed portion 44a which is recessed inward in the radial direction is formed at a position in the circumferential direction of the annular wall 44 which is located in the same direction as the ignition electrode 3. The wall portion on the radially inner side of the concave portion 44a is provided with a target portion 46 located at the upper end of the circumferential central portion thereof and opposed to the upper side of the ignition electrode 3, and is also formed on both sides of the target portion 46 and directed A pair of ignition flame ports 47 of the ignition electrode 3.
燃燒器蓋5形成為圓板狀，在其下表面中央部安裝著與隆起 部43的上端面保留著既定間隙對置的背面板51。在背面板51的外周保留著周向的間隔垂直設置著多個定心片52。並且，通過使這些定心片52的下端部抵接於隆起部43的外周面，燃燒器蓋5相對於燃燒器主體4定心，燃燒器蓋5的下表面外周部抵接於燃燒器主體4的環狀壁44的上端面。而且，在形成於背面板51的朝向上方的凸出部53嵌合到形成於燃燒器蓋5下表面的凹孔中的狀態下，將凸出部53焊接到燃燒器蓋5上，從而實現背面板51對於燃燒器蓋5的固定。The burner cover 5 is formed in a disk shape, and is mounted and raised at the center of the lower surface thereof. The upper end surface of the portion 43 retains the back plate 51 opposed to the predetermined gap. A plurality of centering pieces 52 are vertically disposed at intervals on the outer circumference of the back panel 51 in the circumferential direction. Further, the lower end portion of the centering piece 52 is brought into contact with the outer peripheral surface of the raised portion 43, the burner cover 5 is centered with respect to the burner main body 4, and the outer peripheral portion of the lower surface of the burner cover 5 abuts against the burner body.

上述的噴氣嘴2位於插入支撑筒部12的喉部42的正下方。並且，從噴氣嘴2向喉部42的下端開口噴出燃氣時，從喉部42的上端開口流出的氣流接觸到背面板51的下表面而沿徑向擴散，發生所謂徑向文土里效應，從喉部42的下端開口吸入一次空氣。由此，燃氣和一次空氣的混和氣經由喉部42被供給到燃燒器主體4內。被供給到燃燒器主體4內的混和氣，從形成在環狀壁44上的火焰口45噴出並燃燒，對在省略圖示的爐灶頂板上的三角爐架上載置的被加熱物進行加熱。The above-described air nozzle 2 is located directly below the throat 42 of the insertion support cylinder portion 12. Further, when the gas is blown from the air nozzle 2 to the lower end opening of the throat portion 42, the airflow flowing out from the upper end opening of the throat portion 42 comes into contact with the lower surface of the back surface plate 51 and diffuses in the radial direction, causing a so-called radial soil effect. The air is taken in from the lower end opening of the throat 42. Thereby, the mixed gas of the gas and the primary air is supplied into the burner main body 4 via the throat 42. The mixed gas supplied into the burner main body 4 is ejected and burned from the flame port 45 formed in the annular wall 44, and the object to be heated placed on the triangular hob on the top plate (not shown) is heated.
在此，在喉部42的外周面上形成有以下各部分：圓筒狀的上部嵌合突起部421；圓筒狀的下部嵌合突起部422，位於自上部嵌合突起部421向下側離開的部分，並且直徑小於上部嵌合突起部421；以及圓錐體狀的縮徑部423，位於上部嵌合突起部421與下部嵌合突起部422之間，直徑朝著下方縮减。Here, the outer peripheral surface of the throat portion 42 is formed with a cylindrical upper fitting projection portion 421 and a cylindrical lower fitting projection portion 422 located downward from the upper fitting projection portion 421. The portion that is separated and has a smaller diameter than the upper fitting projection 421; and the tapered reduced diameter portion 423 are located between the upper fitting projection 421 and the lower fitting projection 422, and the diameter is reduced toward the lower side.
此外，在支撑筒部12的內周面形成有以下各部分：上部嵌合凹部121，為圓筒狀，使上部嵌合突起部421以保留相當於插入餘隙的間隙的方式嵌合；下部嵌合凹部122，位於從上部嵌合凹部121向下方離開的部分，具有直徑小於上部嵌合凹部121的圓筒狀，使下部嵌合突起部422以保留相當於插入餘隙的間隙的方式嵌合；以及導引部123，位於上部嵌合凹部121與下部嵌合凹部 122之間，具有朝著下方直徑减小的圓錐體形狀。上部嵌合凹部121的上下方向長度被設定成：在燃燒器主體4的下表面坐落於支撑筒部12上端的狀態下，上部嵌合凹部121的下端比上部嵌合突起部421的下端更位於下方。此外，所謂插入餘隙，是指將喉部42插入支持筒部12所需的最小限度的餘隙，具體是0.05mm左右。Further, the inner peripheral surface of the support tubular portion 12 is formed with the following portions: the upper fitting recess portion 121 has a cylindrical shape, and the upper fitting projection portion 421 is fitted so as to retain a gap corresponding to the insertion clearance; The fitting recessed portion 122 is located at a portion that is downwardly separated from the upper fitting recessed portion 121, and has a cylindrical shape having a smaller diameter than the upper fitting recessed portion 121, and the lower fitting protruding portion 422 is embedded so as to retain a gap corresponding to the insertion clearance. And a guiding portion 123 located at the upper fitting recess 121 and the lower fitting recess Between 122, there is a cone shape that decreases toward the lower diameter. The length of the upper fitting recessed portion 121 in the vertical direction is set such that the lower end of the upper fitting recessed portion 121 is located more than the lower end of the upper fitting projection portion 421 in a state where the lower surface of the burner main body 4 is seated at the upper end of the support tubular portion 12. Below. Further, the insertion clearance refers to a minimum clearance required to insert the throat portion 42 into the support cylinder portion 12, specifically, about 0.05 mm.
此外，為了使喉部42容易插入支持筒部12，在從上部嵌合凹部121的上端向上方延伸的支持筒部12的內周面部分，形成朝著上方直徑擴大的圓錐體狀的上部導引部124，並且，在從下部嵌合突起部422的下端向下方延伸的喉部42的外周面部分，形成朝著下方直徑减小的圓錐體狀的下部導引部424。Further, in order to allow the throat portion 42 to be easily inserted into the support tubular portion 12, a conical upper guide portion that expands in diameter upward is formed on the inner peripheral surface portion of the support tubular portion 12 that extends upward from the upper end of the upper fitting recess portion 121. In the outer peripheral surface portion of the throat portion 42 extending downward from the lower end of the lower fitting projection portion 422, a tapered lower guide portion 424 having a diameter reduced toward the lower side is formed.
根據本實施方式，由於上部嵌合突起部421、下部嵌合突起部422和上部嵌合凹部121、下部嵌合凹部122全都形成為圓筒狀，因此，即使燃燒器主體4的下表面或支撑筒部12的上端的加工公差引起燃燒器主體4的高度變化，各嵌合突起部421、422與各嵌合凹部121、122之間的間隙量也能夠保持插入喉部42所需的最小限度的插入餘隙。因此，燃燒器主體4能夠不搖動而穩定地被支撑在支撑筒部12上。According to the present embodiment, since the upper fitting projection portion 421, the lower fitting projection portion 422, the upper fitting recess portion 121, and the lower fitting recess portion 122 are all formed in a cylindrical shape, even the lower surface of the burner body 4 or the support is provided. The machining tolerance of the upper end of the tubular portion 12 causes a change in the height of the burner body 4, and the amount of the gap between each of the fitting projections 421, 422 and each of the fitting recesses 121, 122 can also maintain the minimum required to be inserted into the throat 42. Insertion clearance. Therefore, the burner main body 4 can be stably supported on the support cylinder portion 12 without shaking.
但是，雖然也可以考慮在支撑筒部12內周面的除上部導引部124以外的上下方向全長上，使喉部42的外周面以保留相當於插入餘隙的間隙的方式嵌合，從而確保喉部42對於支撑筒部12的嵌合部分長度比較長，但這樣做會產生以下問題。亦即，有時若產生大量的溢出湯汁，則溢出湯汁會流到燃燒器主體4的下表面，溢出湯汁因毛細管現象等自在支撑筒部12的上端與燃燒器主體4的下表面之間產生的微小間隙進入支撑筒部12內，溢出湯汁會使喉部42固著在支撑筒部12。這種情况下，如果喉部42對於支撑筒部12的嵌合部位長度如上所述地較長，則溢出湯汁所產生的固著力變強，有可能無法取下燃燒器主體4。However, it is conceivable that the outer peripheral surface of the inner peripheral surface of the support tubular portion 12 in the vertical direction other than the upper guide portion 124 is fitted so as to retain the gap corresponding to the insertion clearance. It is ensured that the length of the fitting portion of the throat portion 42 to the support cylinder portion 12 is relatively long, but this causes the following problem. That is, sometimes, if a large amount of overflow soup is generated, the overflowing soup will flow to the lower surface of the burner main body 4, and the overflow soup will freely support the upper end of the cylindrical portion 12 and the lower surface of the burner main body 4 due to capillary action or the like. A small gap generated between them enters the support cylinder portion 12, and the overflow of the soup causes the throat portion 42 to be fixed to the support cylinder portion 12. In this case, if the length of the fitting portion of the throat portion 42 with respect to the support tubular portion 12 is as long as described above, the fixing force generated by the overflow of the soup becomes strong, and the burner body 4 may not be removed.
此外，為了弱化固著力也可以考慮在支撑筒部12內周面的上下方向中間部形成朝徑向外側凹入的凹面部。但是，凹面部需要使用在徑向伸縮自如的特殊工具進行加工，因此，加工工序複雜，會導致成本上升。Further, in order to weaken the fixing force, it is conceivable to form a concave surface that is recessed outward in the radial direction in the intermediate portion in the vertical direction of the inner circumferential surface of the support tubular portion 12. However, the concave surface needs to be processed by a special tool that is radially expandable and contractible. Therefore, the processing procedure is complicated and the cost is increased.
與此相比，在本實施方式中，將下部嵌合突起部422和下部嵌合凹部122做成直徑比上部嵌合突起部421和上部嵌合凹部121小，在上部嵌合突起部421與下部嵌合突起部422之間形成縮徑部423，並且，使上部嵌合凹部121的下端比上部嵌合突起部421的下端更位於下側，由此，能夠在上部嵌合凹部121及導引部123與縮徑部423之間確保較寬的間隙。因此，在縮徑部423不會發生溢出湯汁引起的喉部42對於支撑筒部12的固著。所以，溢出湯汁所引起的固著力變弱，可以防止燃燒器主體4不能取下的現象。再者，不需要在支撑筒部12內周面的上下方向中間部形成凹面部，加工容易，可避免成本上升。On the other hand, in the present embodiment, the lower fitting projection portion 422 and the lower fitting recess portion 122 are made smaller in diameter than the upper fitting projection portion 421 and the upper fitting recess portion 121, and the projection portion 421 is fitted to the upper portion. The reduced diameter portion 423 is formed between the lower fitting projections 422, and the lower end of the upper fitting recess 121 is positioned lower than the lower end of the upper fitting projection 421, whereby the recess 121 and the guide can be fitted to the upper portion. A wide gap is secured between the lead portion 123 and the reduced diameter portion 423. Therefore, the fixing of the throat portion 42 to the support tubular portion 12 caused by the overflow of the soup does not occur in the reduced diameter portion 423. Therefore, the fixing force caused by the overflow of the soup is weakened, and the phenomenon that the burner body 4 cannot be removed can be prevented. Further, it is not necessary to form a concave portion in the intermediate portion in the vertical direction of the inner peripheral surface of the support tubular portion 12, and the processing is easy, and the increase in cost can be avoided.
此外，將喉部42插入支撑筒部12時，通過圓錐體狀的導引部123進行導引，使得喉部42與支撑筒部12成同心，下部嵌合突起部422及上部嵌合突起部421順利地嵌合到下部嵌合凹部122及上部嵌合凹部121。因此，燃燒器主體4的安裝作業變得容易。Further, when the throat portion 42 is inserted into the support tubular portion 12, it is guided by the conical guide portion 123 such that the throat portion 42 is concentric with the support cylinder portion 12, and the lower fitting projection portion 422 and the upper fitting projection portion are fitted. The 421 is smoothly fitted to the lower fitting recess 122 and the upper fitting recess 121. Therefore, the mounting work of the burner main body 4 becomes easy.
接著，說明關於圖4、圖5所示的第二實施方式的爐灶用燃燒器。第二實施方式的爐灶用燃燒器的基本結構與上述第一實施方式的結構相同，對於與第一實施方式相同的構件、部位，賦予與上述相同的標記。第二實施方式與第一實施方式的區別在於，在下部嵌合凹部122的周向多個位置(例如，3個位置)形成有沿上下方向延伸的槽部125。Next, a burner for a cooktop according to a second embodiment shown in Figs. 4 and 5 will be described. The basic structure of the burner for a cooker according to the second embodiment is the same as that of the above-described first embodiment, and the same members and portions as those of the first embodiment are denoted by the same reference numerals. The second embodiment differs from the first embodiment in that a groove portion 125 extending in the vertical direction is formed at a plurality of positions (for example, three positions) in the circumferential direction of the lower fitting recess portion 122.
由此，可以通過槽部125將進入支撑筒部12的溢出湯汁排出 到支撑筒部12的下方。因此，能夠抑制溢出湯汁滯留在支撑筒部12內而黏牢，提高了防止溢出湯汁引起的喉部42發生固著的功能。Thereby, the overflowing soup entering the support cylinder portion 12 can be discharged through the groove portion 125. It is below the support cylinder portion 12. Therefore, it is possible to suppress the overflow of the soup from staying in the support tube portion 12 and to adhere it, thereby improving the function of preventing the throat 42 from being fixed due to the overflow of the soup.
此外，在第二實施方式中，槽部125的徑向外側的槽面直徑與上部嵌合凹部121相同，從上部嵌合凹部121的下端開始在導引部123及下部嵌合凹部122的上下方向全長上形成了槽部125，但也可以是：槽面直徑小於上部嵌合凹部121，形成從導引部123的下部開始向下方延伸的槽部125。Further, in the second embodiment, the diameter of the groove surface of the groove portion 125 in the radial direction is the same as that of the upper fitting recess 121, and the lower end of the upper fitting recess 121 is above and below the guide portion 123 and the lower fitting recess 122. The groove portion 125 is formed over the entire length of the groove. However, the groove portion may have a smaller groove diameter than the upper fitting recess portion 121, and may have a groove portion 125 extending downward from the lower portion of the guide portion 123.
以上，參照附圖說明了本發明的實施方式，但本發明不限定於上述實施方式。例如，上述實施方式中，在喉部42的外周面的上部嵌合突起部421與下部嵌合突起部422之間形成了朝著下方直徑减小的圓錐體狀的縮徑部423，但也可以是：在上部嵌合突起部421與下部嵌合突起部422之間形成直徑小於上部嵌合突起部421的圓筒狀的縮徑部。這種情况下，縮徑部的直徑可以與下部嵌合突起部422相同，或者比下部嵌合突起部422小。The embodiments of the present invention have been described above with reference to the drawings, but the present invention is not limited to the above embodiments. For example, in the above-described embodiment, a tapered reduced diameter portion 423 having a diameter reduced toward the lower side is formed between the upper fitting projection portion 421 and the lower fitting protruding portion 422 of the outer peripheral surface of the throat portion 42, but A cylindrical reduced diameter portion having a smaller diameter than the upper fitting protrusion portion 421 may be formed between the upper fitting protrusion portion 421 and the lower fitting protruding portion 422. In this case, the diameter of the reduced diameter portion may be the same as or smaller than the lower fitting protrusion portion 422.
此外，上述第二實施方式中，在下部嵌合凹部122形成了沿上下方向延伸的溢出湯汁排出用的槽部125，也可以是：在下部嵌合突起部422形成溢出湯汁排出用的槽部，或者，也可以在下部嵌合凹部122和下部嵌合突起部422上都形成溢出湯汁用的槽部。Further, in the second embodiment, the groove portion 125 for discharging the overflowing juice extending in the vertical direction is formed in the lower fitting recess portion 122, and the lower fitting projection portion 422 may be formed to discharge the overflow soup. In the groove portion, a groove portion for overflowing the soup may be formed on both the lower fitting recess portion 122 and the lower fitting projection portion 422.
