The combustion flame interferes with the combustion flame of the upper burner part. [Technical solution to solve the problem]

為解決前述課題，本發明係一種瓦斯爐用燃燒器，係具備環狀的上層燃燒器部，以及配置於上層燃燒器部的下方且與上層燃燒器部為同心的環狀之下層燃燒器部；其特徵為：上層燃燒器部及下層燃燒器部，係以分別在周方向隔著間隔具有複數個於內周部往徑方向內方開口的火口之內炎式燃燒器構成，下層燃燒器部的火口，係於朝向徑方向內方往下方傾斜的方向開口。並且，本發明之瓦斯爐，係具備前述本發明之瓦斯爐用燃燒器。In order to solve the aforementioned problems, the present invention is a burner for a gas stove, which is provided with a ring-shaped upper burner part and a ring-shaped lower burner part arranged below the upper burner part and concentric with the upper burner part ; It is characterized in that the upper burner part and the lower burner part are composed of internal inflammation type burners with a plurality of flares opening in the radial direction of the inner circumferential part at intervals in the circumferential direction, and the lower burner The fire port of the part is opened in a direction inclined downward toward the inner side of the radial direction. In addition, the gas stove of the present invention includes the burner for the gas stove of the present invention.

依據本發明之瓦斯爐用燃燒器而言，因來自下層燃燒器部的火口的混合氣體朝向斜下方噴出，故藉由燃燒該混合氣體所形成的下層燃燒器部的燃燒焰的位置會往下方偏離而遠離上層燃燒器部的燃燒焰。因此，能夠抑制下層燃燒器部的燃燒焰與上層燃燒器部的燃燒焰互相干擾，而使燃燒性良好。According to the burner for a gas stove of the present invention, because the mixed gas from the flares of the lower burner part is sprayed obliquely downward, the position of the combustion flame of the lower burner part formed by burning the mixed gas is downward Deviation and away from the combustion flame of the upper burner part. Therefore, it is possible to suppress the interference between the combustion flame of the lower burner portion and the combustion flame of the upper burner portion, and improve the combustibility.

另外，於本發明中，較佳為：於上層燃燒器部與下層燃燒器部之間設有空隙，將通過該空隙的空氣的至少一部分作為燃燒用二次空氣被供給至來自下層燃燒器的火口的混合氣體的噴出部位，並且設有：二次空氣導引件，係對於從前述空隙朝向該混合氣體的噴出部位供給的燃燒用二次空氣的流動賦予朝向下方的方向分量。藉此，使下層燃燒器部的燃燒焰更朝向下方，而能夠更為確實地抑制下層燃燒器部的燃燒焰與上層燃燒器部的燃燒焰互相干擾。In addition, in the present invention, it is preferable that a gap is provided between the upper burner portion and the lower burner portion, and at least a part of the air passing through the gap is supplied to the air from the lower burner as secondary air for combustion. A secondary air guide is provided at the ejection portion of the mixed gas of the vent to give a downward direction component to the flow of the secondary air for combustion supplied from the gap toward the ejection portion of the mixed gas. Thereby, the combustion flame of the lower burner part is directed downward, and the interference between the combustion flame of the lower burner part and the combustion flame of the upper burner part can be suppressed more reliably.

另外，於本發明中，較佳為：於上層燃燒器部的底壁部的內周部，設有比上層燃燒器部的火口的下端更往徑方向內方伸展的伸展部。藉此，能夠抑制上層燃燒器部的燃燒焰往下方膨脹，而有助於防止下層燃燒器部的燃燒焰與上層燃燒器部的燃燒焰互相干擾。In addition, in the present invention, it is preferable that the inner peripheral portion of the bottom wall portion of the upper burner portion is provided with an extended portion that extends radially inwardly than the lower end of the burner of the upper burner portion. Thereby, the combustion flame of the upper burner part can be suppressed from expanding downward, and this contributes to preventing the combustion flame of the lower burner part and the combustion flame of the upper burner part from interfering with each other.

參照圖1、圖2，1係瓦斯爐的瓦斯爐本體，2係覆蓋瓦斯爐本體1的上表面的頂板。於瓦斯爐，係設有：瓦斯爐用燃燒器4，係緊鄰於開設在頂板2的燃燒器用開口21，將載置於頂板2上的爐架3之鍋等的烹調容器加熱。爐架3，係具有環狀的爐架框31，以及固定於爐架框31的複數個爐架爪32。另外，於頂板2上，載置有從上方覆蓋燃燒器用開口21內之與瓦斯爐用燃燒器4之間的間隙之燃燒器環22。並且，於瓦斯爐本體1內，設有通過瓦斯爐用燃燒器4所包圍的中央空間掉落之溢出的湯汁的湯汁承接件11。並且，爐架框31，係形成為從上方覆蓋燃燒器環22及後述之上層燃燒器部5的形狀。1 and 2, 1 is the gas stove body of the gas stove, and 2 is the top plate covering the upper surface of the gas stove body 1. The gas stove is provided with a burner 4 for the gas stove, which is adjacent to the burner opening 21 opened in the top plate 2 and heats cooking containers such as a pot of the hob 3 placed on the top plate 2. The hob 3 has an annular hob frame 31 and a plurality of hob claws 32 fixed to the hob frame 31. In addition, on the top plate 2, a burner ring 22 covering the gap between the opening 21 for the burner and the burner 4 for the gas stove is placed from above. In addition, in the gas stove main body 1, there is provided a soup receiver 11 for overflowing soup dropped through the central space surrounded by the gas stove burner 4. Furthermore, the grate frame 31 is formed in a shape which covers the burner ring 22 and the upper burner part 5 mentioned later from above.

瓦斯爐用燃燒器4，係具備環狀的上層燃燒器部5，以及配置於上層燃燒器部5的下方且與上層燃燒器部5為同心的環狀之下層燃燒器部6。上層燃燒器部5及下層燃燒器部6，係以分別在周方向隔著間隔具有複數個於內周部往徑方向內方開口的火口51、61之內炎式燃燒器構成。以下，針對上層燃燒器部5及下層燃燒器部6詳細說明。The burner 4 for a gas furnace includes an annular upper burner part 5 and an annular lower burner part 6 arranged below the upper burner part 5 and concentric with the upper burner part 5. The upper burner part 5 and the lower burner part 6 are constituted by internal flame type burners each having a plurality of flares 51 and 61 that open inwardly in the radial direction in the inner circumferential part at intervals in the circumferential direction. Hereinafter, the upper burner part 5 and the lower burner part 6 will be described in detail.

上層燃燒器部5，係藉由以下者構成：板金製的底壁部52；板金製的外周壁部53，係對於底壁部52的外周部從接合部往上方立起；鑄造物製的上壁部54，係以往徑方向內方伸展的方式固定於外周壁部53的上端部；以及內周部的燃燒器頭部55，係以封塞上壁部54與底壁部52之間的間隙的方式裝卸自如地載置於底壁部52。於燃燒器頭部55，在周方向隔著間隔形成有複數個從下表面往上方凹陷之作為火口51的溝。並且，藉由將燃燒器頭部55載置於底壁部52，溝的下表面會被底壁部52封塞，而藉此在底壁部52與燃燒器頭部55之間區劃形成火口51。又，如圖3所示，火口51係以具有朝向周方向其中一方傾斜的角度的方式於徑方向內方開口。藉此，上層燃燒器部5的燃燒焰會往周方向其中一方迴旋，使烹調容器的加熱效率提升。The upper burner part 5 is composed of the following: a bottom wall part 52 made of sheet metal; an outer peripheral wall part 53 made of sheet metal, which stands up from the junction with respect to the outer peripheral part of the bottom wall part 52; made of casting The upper wall 54 is fixed to the upper end of the outer peripheral wall 53 so as to extend inward in the radial direction; and the burner head 55 at the inner peripheral part is used to seal the space between the upper wall 54 and the bottom wall 52 It is detachably mounted on the bottom wall portion 52 in a manner of a gap. In the burner head 55, a plurality of grooves, which are flares 51, are recessed upward from the lower surface at intervals in the circumferential direction. In addition, by placing the burner head 55 on the bottom wall 52, the lower surface of the groove is blocked by the bottom wall 52, thereby forming a fire port between the bottom wall 52 and the burner head 55 51. Moreover, as shown in FIG. 3, the fire port 51 opens in the radial direction inward so that it may have an angle inclined to one of the circumferential directions. Thereby, the combustion flame of the upper burner part 5 turns to one of the circumferential directions, and the heating efficiency of the cooking container is improved.

並且，於上層燃燒器部5的底壁部52的內周部，設有比火口51的下端更往徑方向內方伸展的伸展部52a。並且，從該伸展部52a往下方延伸之後述的二次空氣導引件8係一體形成於底壁部52。In addition, the inner peripheral portion of the bottom wall portion 52 of the upper burner portion 5 is provided with an extension portion 52 a that extends inward in the radial direction than the lower end of the burner 51. In addition, a secondary air guide 8 to be described later extending downward from the extension portion 52 a is integrally formed on the bottom wall portion 52.

下層燃燒器部6，係藉由以下者構成：板金製的底壁部62，係於內周側形成有往上方立起並往徑方向內方伸展的凸緣部62a；以及板金製的上壁部63，係形成有從對於底壁部62的外周部之接合部往上方立起並往徑方向內方延伸的凸緣部63a。並且，使底壁部62的凸緣部62a與上壁部63的凸緣部63a接合。並且，於底壁部62的凸緣部62a及上壁部63的凸緣部63a，在周方向錯開位置地形成有複數個往下方凹陷的凹部62b及往上方凹陷的凹部63b，以凹部62b、63b內的空隙構成火口61。又，如圖4所示，火口61亦與上層燃燒器部5的火口51相同，以具有朝向周方向其中一方傾斜的角度的方式於徑方向內方開口，而下層燃燒器部6的燃燒焰亦會往周方向其中一方迴旋。The lower burner portion 6 is composed of the following: a bottom wall portion 62 made of sheet metal, a flange portion 62a that rises upward and extends radially inward is formed on the inner peripheral side; and an upper portion made of sheet metal The wall portion 63 is formed with a flange portion 63a that rises upward from the junction with the outer peripheral portion of the bottom wall portion 62 and extends inward in the radial direction. Then, the flange portion 62 a of the bottom wall portion 62 and the flange portion 63 a of the upper wall portion 63 are joined. In addition, in the flange portion 62a of the bottom wall portion 62 and the flange portion 63a of the upper wall portion 63, a plurality of downwardly recessed recessed portions 62b and upwardly recessed recessed portions 63b are formed at positions shifted in the circumferential direction. The recessed portion 62b , The gap in 63b constitutes the fire port 61. In addition, as shown in FIG. 4, the flares 61 are the same as the flares 51 of the upper burner section 5, and open in the radial direction so as to have an angle inclined to one of the circumferential directions, while the combustion flames of the lower burner section 6 It will also swing to one side of the circle.

另外，手難以觸其下層燃燒器部6而不易清掃。因此，係使上層燃燒器部5的底壁部52的內徑D1(二次空氣導引件8的下端部的直徑)為下層燃燒器部6的火口61所開口之內周部的直徑D2以下。藉此，下層燃燒器部6的火口61所開口的內周部，從上方觀察時係隱藏於上層燃燒器部5的底壁部52的下方。因此，能夠防止沿著烹調容器的底面滴下的溢出的湯汁附著於下層燃燒器部6的火口61。In addition, it is difficult to touch the lower burner part 6 with hands and it is difficult to clean. Therefore, the inner diameter D1 (the diameter of the lower end of the secondary air guide 8) of the bottom wall portion 52 of the upper burner portion 5 is the diameter D2 of the inner peripheral portion opened by the burner 61 of the lower burner portion 6 the following. Thereby, the inner peripheral part of the burner 61 of the lower burner part 6 is hidden below the bottom wall part 52 of the upper burner part 5, when viewed from above. Therefore, it is possible to prevent the overflowing soup dripping along the bottom surface of the cooking container from adhering to the burner 61 of the lower burner portion 6.

對於上層燃燒器部5及下層燃燒器部6，透過圖外之各別的混合管供給有混合氣體。並且，藉由操作圖示省略之火力調節用的操作件，能夠在僅使下層燃燒器部6以最小火力燃燒的小火至使下層燃燒器部6及上層燃燒器部5分別以最大火力燃燒的大火的範圍進行瓦斯爐用燃燒器4的火力調節。又，為了能夠使小火對於烹調容器的加熱量盡可能減少，係將下層燃燒器部6的最小火力設定為比上層燃燒器部5的最小火力更小。並且，為了抑制接近下層燃燒器部6的湯汁承接件11的加熱而能夠防止溢出的湯汁燒乾於湯汁承接件11，係將下層燃燒器部6的最大火力亦設定為比上層燃燒器部5的最大火力更小。The upper burner part 5 and the lower burner part 6 are supplied with mixed gas through separate mixing pipes not shown in the figure. In addition, by operating the operating element for adjusting the heating power, which is omitted from the illustration, it is possible to burn only the lower burner section 6 with the minimum heating power from a small fire to make the lower burner section 6 and the upper burner section 5 burn with the maximum heating power. The fire power of the burner 4 for the gas stove is adjusted in the range of the large fire. In addition, in order to reduce the amount of heating of the cooking vessel by the small fire as much as possible, the minimum heating power of the lower burner portion 6 is set to be smaller than the minimum heating power of the upper burner portion 5. In addition, in order to suppress the heating of the soup receiver 11 close to the lower burner portion 6 and prevent the overflowing soup from being dried on the soup receiver 11, the maximum heating power of the lower burner portion 6 is also set to be higher than that of the upper burner. The maximum firepower of the device part 5 is smaller.

然而，若下層燃燒器部6的燃燒焰與上層燃燒器部5的燃燒焰互相干擾，則燃燒性會惡化。因此，於本實施形態中，係使下層燃燒器部6的火口61於朝向徑方向內方往下方傾斜的方向開口。藉此，混合氣體會從下層燃燒器部6的火口61朝向斜下方噴出。因此，能夠使藉由燃燒該混合氣體所形成的下層燃燒器部6的燃燒焰的位置往下方偏離而遠離上層燃燒器部5的燃燒焰。因此，能夠抑制下層燃燒器部6的燃燒焰與上層燃燒器部5的燃燒焰互相干擾，而使燃燒性良好。However, if the combustion flame of the lower burner portion 6 and the combustion flame of the upper burner portion 5 interfere with each other, the combustibility deteriorates. Therefore, in the present embodiment, the burner 61 of the lower-stage combustor portion 6 is opened in a direction inclined downward toward the inner side of the radial direction. Thereby, the mixed gas is jetted obliquely downward from the flares 61 of the lower burner part 6. Therefore, the position of the combustion flame of the lower burner part 6 formed by burning the mixed gas can be shifted downward and away from the combustion flame of the upper burner part 5. Therefore, it is possible to suppress the interference between the combustion flame of the lower burner portion 6 and the combustion flame of the upper burner portion 5, and to improve the combustibility.

並且，於上層燃燒器部5與下層燃燒器部6之間設有空隙7，將通過該空隙7的空氣的至少一部分(於本實施形態中係全部)作為燃燒用二次空氣被供給至來自下層燃燒器部6的火口61的混合氣體的噴出部位。並且，於本實施形態中，設有從上層燃燒器部5的底壁部52的伸展部52a往下方延伸之筒狀的二次空氣導引件8。並且，對於從前述空隙7朝向來自下層燃燒器部6的火口61的混合氣體的噴出部位供給的燃燒用二次空氣的流動，藉由二次空氣導引件8賦予朝向下方的方向分量。藉此，使下層燃燒器部6的燃燒焰更朝向下方，而能夠更為確實地抑制下層燃燒器部6的燃燒焰與上層燃燒器部5的燃燒焰互相干擾。In addition, a gap 7 is provided between the upper combustor portion 5 and the lower combustor portion 6, and at least a part of the air passing through the gap 7 (in this embodiment, all) is supplied as secondary air for combustion. The position where the mixed gas is ejected from the burner 61 of the lower burner part 6. In addition, in this embodiment, a cylindrical secondary air guide 8 extending downward from the extended portion 52a of the bottom wall portion 52 of the upper burner portion 5 is provided. In addition, the flow of the secondary air for combustion supplied from the gap 7 toward the ejection site of the mixed gas from the burner 61 of the lower burner portion 6 is given a downward direction component by the secondary air guide 8. As a result, the combustion flame of the lower burner portion 6 is directed downward, and the interference between the combustion flame of the lower burner portion 6 and the combustion flame of the upper burner portion 5 can be suppressed more reliably.

並且，於本實施形態中，於上層燃燒器部5的底壁部52的內周部，如前述般設有比火口51的下端更往徑方向內方伸展的伸展部52a。藉此，能夠抑制上層燃燒器部5的燃燒焰往下方膨脹，而有助於防止下層燃燒器部6的燃燒焰與上層燃燒器部5的燃燒焰互相干擾。In addition, in the present embodiment, the inner peripheral portion of the bottom wall portion 52 of the upper burner portion 5 is provided with a stretched portion 52a that extends radially inwardly than the lower end of the burner 51 as described above. Thereby, the combustion flame of the upper burner part 5 can be suppressed from expanding downward, and this contributes to preventing the combustion flame of the lower burner part 6 and the combustion flame of the upper burner part 5 from interfering with each other.

以上，雖參照圖式針對本發明之實施形態進行了說明，然而本發明不限於此。例如，於前述實施形態中，係將二次空氣導引件8一體形成於上層燃燒器部5的底壁部52，然而將與上層燃燒器部5為不同個體的二次空氣導引件8設於下層燃燒器部6的上側亦可。並且，於前述實施形態中，上層燃燒器部5的底壁部52為板金製，然而亦可為鑄造物製。在此情形，於比底壁部52的伸展部52a更靠外側部分豎設環狀壁，於該環狀壁形成作為火口51的溝，並以就座於該環狀壁的上表面的方式設置燃燒器頭部55亦可。Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to this. For example, in the foregoing embodiment, the secondary air guide 8 is integrally formed on the bottom wall portion 52 of the upper burner portion 5, but the secondary air guide 8 is a different individual from the upper burner portion 5. It may be provided on the upper side of the lower burner part 6. In addition, in the foregoing embodiment, the bottom wall portion 52 of the upper burner portion 5 is made of sheet metal, but it may be made of a cast product.
