Description

本発明は、コンロ本体と、コンロ本体の上面を覆う天板と、天板に開設したバーナ用開口を通して天板上に突出するコンロバーナと、天板上にバーナ用開口を囲うようにして載置される五徳とを備えるガスコンロに関する。   The present invention includes a stove body, a top plate that covers the top surface of the stove body, a stove burner that protrudes on the top plate through a burner opening provided in the top plate, and a burner opening that surrounds the burner opening on the top plate. It relates to a gas stove with five virtues.

従来、この種のガスコンロとして、コンロバーナに外挿した状態で天板上に載置されるバーナリングを備え、このバーナリングに五徳の環状の五徳枠を外嵌させて、五徳を位置決めするものが知られている。また、天板に、バーナ用開口の周縁部に位置させて、五徳の環状の五徳枠が外嵌する上記バーナリングに相当する環状***部を絞り成形したガスコンロも知られている（例えば、特許文献１参照）。これによれば、バーナリングが不要になり、部品点数を削減してコストダウンを図ることができる。   Conventionally, this kind of gas stove has a burner ring that is placed on the top plate in an extrapolated state on the stove burner, and the virtues are positioned by externally fitting a five-virtual annular virtuosity frame to this burner ring. It has been known. A gas stove is also known in which an annular ridge corresponding to the above-described burner ring, which is positioned on the top plate at the peripheral edge of the burner opening and fitted with a five-virtual annular virtuosity frame, is drawn (for example, a patent). Reference 1). According to this, burnering becomes unnecessary, and the number of parts can be reduced to reduce the cost.

然し、天板に環状***部を絞り成形すると、以下の不具合を生ずることが判明した。即ち、環状***部は、コンロバーナの火炎からの輻射熱により加熱されやすく、環状***部からの入熱で天板が熱膨張して、環状***部が上方に変位するように天板が変形しやすくなる。そして、環状***部が一旦上方に変位すると、火炎に近づくために、環状***部への入熱量が増加して、天板の熱膨張による環状***部の上方への変位量がかなり大きくなってしまう。そのため、コンロバーナの燃焼停止で天板が冷却収縮して初期状態に戻ろうとしたとき、大きな反転音が発生して使用者を驚かせてしまう。   However, it has been found that the following problems occur when an annular ridge is drawn on the top plate. In other words, the annular ridge is easily heated by the radiant heat from the flame of the burner, the top plate is thermally expanded by heat input from the annular ridge, and the top plate is deformed so that the annular ridge is displaced upward. It becomes easy. And once the annular ridge is displaced upward, the amount of heat input to the annular ridge increases to approach the flame, and the upward displacement of the annular ridge due to the thermal expansion of the top plate becomes considerably large. End up. For this reason, when the top plate cools and contracts due to the stop of combustion of the stove burner and tries to return to the initial state, a large reversing sound is generated and the user is surprised.

特開２０１３−５７４６１号公報JP 2013-57461 A

本発明は、以上の点に鑑み、バーナ燃焼時における環状***部の上方への変位を抑制して、冷却時に天板で大きな反転音が発生することを防止できるようにしたガスコンロを提供することをその課題としている。   In view of the above, the present invention provides a gas stove that suppresses the upward displacement of the annular ridge during burner combustion and prevents the occurrence of a large reversal sound at the top plate during cooling. Is the issue.

上記課題を解決するために、本発明は、コンロ本体と、コンロ本体の上面を覆う天板と、天板に開設したバーナ用開口を通して天板上に突出するコンロバーナと、天板上にバーナ用開口を囲うようにして載置される五徳とを備えるガスコンロであって、天板に、バーナ用開口の周縁部に位置させて、五徳の環状の五徳枠が外嵌する環状***部が絞り成形されるものにおいて、天板の下面に、環状***部から天板の一辺側にのびる補強部材が固定され、補強部材の天板の一辺側の端部に、上方に浮き上がらないようコンロ本体に係合する係合部が形成されることを特徴とする。   In order to solve the above-mentioned problems, the present invention provides a stove body, a top plate that covers the top surface of the stove body, a burner that projects on the top plate through a burner opening provided in the top plate, and a burner on the top plate. A gas stove comprising a virtues placed so as to surround the opening for use, and is located on the top plate at the peripheral edge of the opening for the burner, and the annular bulging portion on which the virtually annular virtuosity frame is fitted is throttled In the molded object, a reinforcing member extending from the annular ridge to one side of the top plate is fixed to the lower surface of the top plate, and the stove body is prevented from floating upward at the end of the reinforcing plate on one side of the top plate. An engaging portion to be engaged is formed.

本発明によれば、補強部材の端部の係合部が上方に浮き上がらないようにコンロ本体に係合するため、コンロバーナ燃焼時における環状***部の上方への変位が補強部材により抑制される。その結果、冷却時に天板で大きな反転音が発生することを防止できる。   According to the present invention, since the engaging portion at the end portion of the reinforcing member is engaged with the stove body so as not to float upward, the upward displacement of the annular raised portion during combustion of the stove burner is suppressed by the reinforcing member. . As a result, it is possible to prevent a large inversion sound from being generated on the top plate during cooling.

ところで、天板の後部に、コンロ本体内に組み込んだグリルの排気口を開設し、この排気口を覆う排気ガードを天板の後部上面に載置すると共に、排気ガードの下に位置する部分で天板をグリルの天井部にネジ止めすることがある。この場合、冷却時に天板が前上がりに反り返って、天板の前辺部分がコンロ本体から浮き上がってしまう可能性がある。そのため、排気ガードの下に位置する天板の部分で天板をグリルの天井部にネジ止めする場合、補強部材がのびる天板の前記一辺側は天板の前辺側であることが望ましい。これによれば、補強部材が天板前辺側に位置する係合部でコンロ本体に係合することになり、冷却時の天板の反り返りで天板の前辺部分がコンロ本体から浮き上がることを確実に防止できる。   By the way, at the rear part of the top plate, an exhaust port for the grill incorporated in the stove body is opened, and an exhaust guard that covers this exhaust port is placed on the upper surface of the rear part of the top plate, and at the part located under the exhaust guard. The top plate may be screwed to the ceiling of the grill. In this case, the top plate may warp forward during cooling, and the front side portion of the top plate may float from the stove body. Therefore, when the top plate is screwed to the ceiling portion of the grill at the portion of the top plate located under the exhaust guard, the one side of the top plate on which the reinforcing member extends is preferably the front side of the top plate. According to this, the reinforcing member is engaged with the stove body at the engaging portion located on the front side of the top plate, and the front side portion of the top plate is lifted from the stove body due to the warping of the top plate during cooling. It can be surely prevented.

図１を参照して、１は、本発明の実施形態のガスコンロを示している。このガスコンロ１は、コンロ本体２と、コンロ本体２の上面を覆う天板３と、天板３の左右２箇所に開設したバーナ用開口３１，３１を通して天板３上に突出する左右一対のコンロバーナ４，４と、天板３上にバーナ用開口３１，３１を囲うようにして載置される左右一対の五徳５，５と、コンロ本体２内に組み込んだグリル６とを備えている。コンロ本体２の前面には、各コンロバーナ４用と図示省略したグリルバーナ用の点消火ボタン２１と火力調節レバー２２とが配置されている。   Referring to FIG. 1, reference numeral 1 denotes a gas stove according to an embodiment of the present invention. The gas stove 1 includes a stove body 2, a top plate 3 that covers the top surface of the stove body 2, and a pair of left and right stoves that protrude on the top plate 3 through the burner openings 31, 31 provided at two left and right sides of the top plate 3. Burners 4 and 4, a pair of left and right virtues 5 and 5 placed on the top plate 3 so as to surround the burner openings 31 and 31, and a grill 6 incorporated in the stove main body 2 are provided. On the front surface of the stove main body 2, a fire extinguishing button 21 and a heating power adjusting lever 22 for each of the stove burners 4 and a grill burner (not shown) are arranged.

また、図２も参照して、天板３の後部には、グリル６の天井部６１の後端に開口する排気流出口６２が臨む排気口３２が開設され、この排気口３２を覆う排気ガード７が天板３の後部上面に載置されている。そして、排気ガード７の下に位置する天板３の部分に固定孔３３を形成すると共に、グリル６の天井部６１の固定孔３３に合致する部分にネジ孔６３を形成し、固定孔３３を通してネジ孔６３に螺合するネジにより天板３をグリル６の天井部６１にネジ止めし、使用者が容易に天板３を取外すことができないようにしている。尚、ネジ止め箇所は排気ガード７で覆われて外観に現れず、体裁を損なうことはない。   Referring also to FIG. 2, an exhaust port 32 is formed at the rear portion of the top plate 3 so as to face an exhaust outlet 62 opened at the rear end of the ceiling portion 61 of the grill 6. 7 is placed on the upper surface of the rear part of the top plate 3. A fixing hole 33 is formed in the portion of the top plate 3 located under the exhaust guard 7, and a screw hole 63 is formed in a portion matching the fixing hole 33 of the ceiling portion 61 of the grill 6. The top plate 3 is screwed to the ceiling portion 61 of the grill 6 with screws that are screwed into the screw holes 63 so that the user cannot easily remove the top plate 3. In addition, a screwing location is covered with the exhaust guard 7 and does not appear on the appearance, and the appearance is not impaired.

各五徳５は、環状の五徳枠５１に放射状に複数の五徳爪５２を取付けて成るものである。また、天板３には、各バーナ用開口３１の周縁部に位置させて、環状***部３４が絞り成形されており、各五徳５の五徳枠５１を環状***部３４に外嵌させて、各五徳５を位置決めしている。   Each of the five virtues 5 is formed by attaching a plurality of five virtue claws 52 radially to an annular five virtue frame 51. The top plate 3 has an annular ridge 34 formed at the periphery of each burner opening 31, and the five virtues 5 of the five virtues 5 are externally fitted to the annular ridge 34. Each Gotoku 5 is positioned.

ところで、環状***部３４は、コンロバーナ４の火炎からの輻射熱により加熱されやすく、環状***部３４からの入熱で天板３が熱膨張して、環状***部３４が上方に変位するように天板３が変形しやすくなる。そして、環状***部３４が一旦上方に変位すると、火炎に近づくために、環状***部３４への入熱量が増加して、天板３の熱膨張による環状***部３４の上方への変位量がかなり大きくなってしまう。そのため、コンロバーナ４の燃焼停止で天板３が冷却収縮して初期状態に戻ろうとしたとき、大きな反転音が発生して使用者を驚かせてしまう。また、本実施形態の如く天板３が排気ガード７の下に位置する部分でグリル６の天井部６１にネジ止めされていると、冷却時に天板３が前上りに反り返って、天板３の前辺部分がコンロ本体２から浮き上がってしまう可能性がある。   By the way, the annular ridge 34 is easily heated by the radiant heat from the flame of the burner 4 so that the top plate 3 is thermally expanded by the heat input from the annular ridge 34 and the annular ridge 34 is displaced upward. The top plate 3 is easily deformed. Then, once the annular ridge 34 is displaced upward, the amount of heat input to the annular ridge 34 is increased to approach the flame, and the upward displacement of the annular ridge 34 due to the thermal expansion of the top plate 3 is increased. It becomes quite large. For this reason, when the top plate 3 is cooled and contracted by the combustion stop of the stove burner 4 and attempts to return to the initial state, a large reversal sound is generated and the user is surprised. Further, when the top plate 3 is screwed to the ceiling 61 of the grill 6 at a portion located below the exhaust guard 7 as in the present embodiment, the top plate 3 warps forward when cooling, and the top plate 3 There is a possibility that the front side portion of the will rise from the stove body 2.

そこで、本実施形態では、天板３の下面に、各環状***部３４から天板３の前辺側にのびる補強部材３５を溶接等で固定し、補強部材３５の天板３の前辺側の端部、即ち、前端部に、図２、図３に示す如く、上方に浮き上がらないようにコンロ本体２に係合する係合部３５ａを形成している。より具体的に説明すれば、補強部材３５を左右両側に下方への折り曲げ部３５ｂを有する断面コ字状の部材で構成し、補強部材３５の前端部に、各折り曲げ部３５ｂから前方に突出する爪片状の係合部３５ａを形成している。また、コンロ本体２の前面上端のフレーム２３に、各補強部材３５の係合部３５ａに対応するスリット２４を形成している。そして、係合部３５ａをスリット２４に挿入してから天板３を前方に少許ずらして、係合部３５ａをスリット２４より前方のフレーム２３部分の下面に上方に浮き上がらないように係合させ、この状態で天板３を固定孔３３においてグリル６の天井部６１にネジ止めする。   Therefore, in the present embodiment, a reinforcing member 35 extending from the annular ridges 34 to the front side of the top plate 3 is fixed to the lower surface of the top plate 3 by welding or the like, and the front side of the top plate 3 of the reinforcing member 35 is fixed. As shown in FIGS. 2 and 3, an engaging portion 35a that engages with the stove main body 2 is formed at the end portion, that is, the front end portion so as not to float upward. More specifically, the reinforcing member 35 is formed of a U-shaped member having bent portions 35b downward on the left and right sides, and protrudes forward from the bent portions 35b to the front end portion of the reinforcing member 35. A claw piece-like engaging portion 35a is formed. Further, a slit 24 corresponding to the engaging portion 35 a of each reinforcing member 35 is formed in the frame 23 at the upper front end of the stove body 2. Then, after inserting the engaging portion 35a into the slit 24, the top plate 3 is slightly shifted forward, and the engaging portion 35a is engaged with the lower surface of the frame 23 portion ahead of the slit 24 so as not to float upwardly. In this state, the top plate 3 is screwed to the ceiling portion 61 of the grill 6 through the fixing hole 33.

これによれば、コンロ本体２に対する係合部３５ａの係合で補強部材３５全体の上方への変位が防止され、そのため、環状***部３４がコンロバーナ４の燃焼時に上方に変位することを補強部材３５により抑制できる。その結果、冷却時に天板３で大きな反転音が発生することを防止できる。また、補強部材３５が天板３の前辺側に位置する係合部３５ａでコンロ本体２に係合することになり、冷却時の天板３の反り返りで天板３の前辺部分がコンロ本体２から浮き上がることを確実に防止できる。   According to this, the engagement of the engaging portion 35a with the stove main body 2 prevents the entire reinforcing member 35 from being displaced upward, so that the annular ridge 34 is reinforced to displace upward when the stove burner 4 burns. It can be suppressed by the member 35. As a result, it is possible to prevent a large inversion sound from being generated on the top plate 3 during cooling. Further, the reinforcing member 35 is engaged with the stove main body 2 by the engaging portion 35a located on the front side of the top plate 3, and the front side portion of the top plate 3 is caused by the warp of the top plate 3 during cooling. It is possible to reliably prevent floating from the main body 2.

以上、本発明の実施形態について図面を参照して説明したが、本発明はこれに限定されない。例えば、上記実施形態は、グリル付きであって、天板３後部をグリル６の天井部６１にネジ止めしているが、天板３後部をネジ止めしないグリル付きやグリル無しのガスコンロにも本発明を適用でき、この場合、補強部材３５は、環状***部３４から天板３の後辺側や左右一方の側辺側にのびていてもよい。   As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this. For example, the above embodiment is provided with a grill, and the rear portion of the top plate 3 is screwed to the ceiling portion 61 of the grill 6, but this is also applied to a gas stove with or without a grill that does not screw the rear portion of the top plate 3. The invention can be applied, and in this case, the reinforcing member 35 may extend from the annular ridge 34 to the rear side of the top plate 3 or one of the left and right sides.
