An upper end side is configured to be open, and a housing portion that houses the front gas burner and the rear gas burner,
A top plate attached to the upper end of the housing,
With
The top plate section,
A plurality of openings are formed while being formed in a plate shape, and at least one of the plurality of openings is configured as a front opening through which the front gas burner is inserted, and at least one of the plurality of openings is formed as the rear gas burner. A top plate main body configured as a rear opening through which is inserted,
A first reinforcing member extending along the lateral direction and fixed to a back surface of the top plate main body at a position forward of the front opening;

上記のガスコンロは、裏面全体に大きな一枚板の補強部材を配置する構成に代えて、第１〜第５補強部材によって効果的に補強することができ、補強部材の軽量化を図ることができる。特に、横方向各位置での変形を抑える対策としては、第１補強部材を前側開口部よりも前方側において横方向に沿って配置し、第２補強部材を前側開口部よりも後方側且つ後側開口部よりも前方側において横方向に沿って配置し、第３補強部材を前記後側開口部よりも後方側において横方向に沿って配置して対策している。このような構成であるため、前側開口部及び後側開口部の前後のスペースを有効に利用し、強度を確保しやすい構成で効率よく補強部材を配置することができる。更に、前後方向各位置での変形を抑える対策としては、前後方向に沿って延びる第４補強部材及び第５補強部材を左右両側に配置し且つそれぞれを第２補強部材に連結する形で対策している。このような構成であるため、左右両側のスペースを有効に利用しつつ、より一層強度を確保しやすい構成で効率よく補強部材を配置することができる。しかも、軽量化を図りつつ、荷重が加わりやすい天板本体部の左右両縁部付近及び前後両縁部付近、及びガスバーナの熱の影響を受けやすい中間領域（前後方向において前側開口部と後側開口部との間の領域）付近に対し重点的に補強することができるため、軽量化と強度確保の両立を図ることができる。   The above gas stove can be effectively reinforced by the first to fifth reinforcing members instead of a configuration in which a large single-plate reinforcing member is arranged on the entire back surface, and the weight of the reinforcing members can be reduced. . In particular, as a countermeasure for suppressing deformation at each position in the lateral direction, the first reinforcing member is arranged along the lateral direction on the front side of the front opening, and the second reinforcing member is located on the rear side and rear of the front opening. A countermeasure is provided by arranging the third reinforcing member in the lateral direction on the rear side of the rear opening, with the third reinforcing member being disposed on the front side of the side opening. With such a configuration, the reinforcing member can be efficiently arranged with a configuration in which the strength is easily ensured by effectively utilizing the space before and after the front opening and the rear opening. Further, as a measure to suppress deformation at each position in the front-rear direction, a fourth reinforcement member and a fifth reinforcement member extending in the front-rear direction are arranged on both left and right sides, and each is connected to the second reinforcement member. ing. Due to such a configuration, the reinforcing member can be efficiently arranged with a configuration that can further ensure strength while effectively utilizing the spaces on both the left and right sides. Moreover, while reducing the weight, the top and bottom edges near the left and right edges and near the front and rear edges of the top plate body, where the load is apt to be applied, and the intermediate area that is easily affected by the heat of the gas burner (the front opening and the rear Since it is possible to mainly reinforce the vicinity of the region (between the opening and the opening), it is possible to achieve both reduction in weight and securing of strength.

１−５．効果
上記のガスコンロ１は、裏面全体に大きな一枚板の補強部材を配置する構成に代えて、第１〜第５補強部材によって効果的に補強することができ、補強部材の軽量化を図ることができる。特に、横方向各位置での変形を抑える対策としては、第１補強部材８１を前側開口部２１Ａ，２１Ｂよりも前方側において横方向に沿って配置し、第２補強部材８２を前側開口部２１Ａ，２１Ｂよりも後方側且つ後側開口部２１Ｃよりも前方側において横方向に沿って配置し、第３補強部材８３を前記後側開口部２１Ｃよりも後方側において横方向に沿って配置して対策している。このような構成であるため、前側開口部２１Ａ，２１Ｂ及び後側開口部２１Ｖの前後のスペースを有効に利用し、強度を確保しやすい構成で効率よく補強部材を配置することができる。更に、前後方向各位置での変形を抑える対策としては、前後方向に沿って延びる第４補強部材８４及び第５補強部材８５を左右両側に配置し且つそれぞれを第２補強部材８２に連結する形で対策している。このような構成であるため、左右両側のスペースを有効に利用しつつ、より一層強度を確保しやすい構成で効率よく補強部材を配置することができる。しかも、軽量化を図りつつ、荷重が加わりやすい天板本体部２０の左右両縁部付近及び前後両縁部付近、及びガスバーナの熱の影響を受けやすい中間領域（前後方向において前側開口部２１Ａ，２１Ｂと後側開口部２１Ｃとの間の領域）付近に対し重点的に補強することができるため、軽量化と強度確保の両立を図ることができる。 1-5. Effect The gas stove 1 can be effectively reinforced by the first to fifth reinforcing members instead of a configuration in which a large single-plate reinforcing member is arranged on the entire back surface, and the weight of the reinforcing members can be reduced. Can be. In particular, as a measure for suppressing deformation at each position in the lateral direction, the first reinforcing member 81 is disposed along the lateral direction on the front side of the front openings 21A and 21B, and the second reinforcing member 82 is disposed on the front opening 21A. , 21B are arranged along the lateral direction on the rear side of the rear opening 21C and the third reinforcing member 83 is arranged on the rear side of the rear opening 21C along the lateral direction. We are taking measures. With such a configuration, the space before and after the front openings 21A and 21B and the rear opening 21V can be effectively used, and the reinforcing member can be efficiently arranged with a configuration that easily secures strength. Further, as a measure for suppressing deformation at each position in the front-rear direction, a fourth reinforcing member 84 and a fifth reinforcing member 85 extending along the front-rear direction are arranged on both left and right sides, and each is connected to the second reinforcing member 82. Is taking measures. Due to such a configuration, the reinforcing member can be efficiently arranged with a configuration that can further ensure strength while effectively utilizing the spaces on both the left and right sides. Moreover, while reducing the weight, the vicinity of the left and right edges and the vicinity of the front and rear edges of the top plate body 20 to which a load is apt to be applied, and the intermediate region (the front opening 21A, Since it is possible to intensively reinforce the vicinity of the area between the rear opening 21C and the rear opening 21C, it is possible to achieve both reduction in weight and securing of strength.

また、前側開口部は、天板本体部２０の左右方向一方寄りに形成される第１前側開口部２１Ａと、天板本体部２０の左右方向他方寄りに形成される第２前側開口部２１Ｂと、を有し、前側ガスバーナは、第１前側開口部２１Ａに挿し通される第１前側ガスバーナと、第２前側開口部２１Ｂに挿し通される第２前側ガスバーナと、を有し、第１補強部材８１及び第２補強部材８２に連結された状態で第１前側開口部２１Ａと第２前側開口部２１Ｂとの間に配置される第６補強部材８６，８７を備えている。このような構成とすれば、第１前側開口部２１Ａと第２前側開口部２１Ｂの間の領域に補強部材を効率的に配置して強度を一層高めることができる。特に、第１前側開口部２１Ａと第２前側開口部２１Ｂの間の領域は熱による影響が極めて大きいため、このような領域に、強度を確保しやすい形で第６補強部材を配置すれば、より効果的である。   In addition, the front opening includes a first front opening 21A formed on one side in the left-right direction of the top plate body 20 and a second front opening 21B formed on the other side in the left-right direction of the top plate body 20. The front gas burner has a first front gas burner inserted through the first front opening 21A and a second front gas burner inserted through the second front opening 21B, and has a first reinforcement. Sixth reinforcing members 86 and 87 are provided between the first front opening 21A and the second front opening 21B while being connected to the member 81 and the second reinforcing member 82. With such a configuration, the reinforcing member can be efficiently disposed in a region between the first front opening 21A and the second front opening 21B, and the strength can be further increased. In particular, since the area between the first front opening 21A and the second front opening 21B is greatly affected by heat, if the sixth reinforcing member is arranged in such an area in such a manner that strength is easily ensured, More effective.

更に、ガスコンロ１は、前側開口部に沿って配置される環状形態をなすとともに少なくとも一部が前側開口部の周囲において天板本体部２０の上面を覆う構成をなし且つ前側ガスバーナが挿し通される前側リング部と、天板本体部２０の裏面側に配置されるとともに前側リング部に固定され且つ前側ガスバーナが挿し通される前側板状部材と、前側リング部と前側板状部材とを連結する前側連結部材と、を有する前側内枠部（中央側内枠部６１，６２）を備えている。そして、第１補強部材８１は、前側板状部材の前端側の第１部位によって天板本体部２０に向けて押圧され、第２補強部材８２は、前側板状部材の後端側の第２部位によって天板本体２０部に向けて押圧される構成となっている。このようにすれば、安定的に固定された前側内枠部の一部を利用して、第１補強部材８１及び第２補強部材８２のそれぞれの一部を天板本体部２０側に向けて押圧するように保持することができるため、ガスコンロの製造時又は製造後において補強部材を効率的に保持し得る構成をより簡易に実現することができる。しかも、他用途に利用される前側内枠部（中央側内枠部６１，６２）を梁部材として兼用することができるため、軽量化を図りつつ一層の強度向上を達成し得る。   Further, the gas stove 1 has an annular shape arranged along the front opening and at least a part covers the top surface of the top plate body 20 around the front opening, and the front gas burner is inserted therethrough.

Then, the first reinforcing member 81 is pressed toward the top plate body 20 by the first portion on the front end side of the front plate-like member, and the second reinforcing member 82 is pressed on the second end on the rear end side of the front plate-like member. It is configured to be pressed toward the top plate body 20 by a part. With this configuration, a part of each of the first reinforcing member 81 and the second reinforcing member 82 is directed toward the top plate main body 20 by using a part of the front inner frame part that is stably fixed. Since the holding member can be held so as to be pressed, a configuration capable of holding the reinforcing member efficiently at the time of manufacturing the gas stove or after the manufacturing can be more easily realized. In addition, the front inner frame portions (central inner frame portions 61 and 62) used for other purposes can also be used as beam members, so that further improvement in strength can be achieved while reducing weight.

更に、ガスコンロ１は、第１前側開口部２１Ａに沿って配置される環状形態をなすとともに少なくとも一部が第１前側開口部２１Ａの周囲において天板本体部２０の上面を覆う構成をなし且つ第１前側ガスバーナが挿し通される第１前側リング部と、天板本体部２０の裏面側に配置されるとともに第１前側リング部に固定され且つ第１前側ガスバーナが挿し通される第１前側板状部材と、第１前側リング部と第１前側板状部材とを連結する第１前側連結部材と、を有する第１前側内枠部（中央側内枠部６１）を備えている。そして、第２前側開口部２１Ｂに沿って配置される環状形態をなすとともに少なくとも一部が第２前側開口部２１Ｂの周囲において天板本体部２０の上面を覆う構成をなし且つ第２前側ガスバーナが挿し通される第２前側リング部と、天板本体部２０の裏面側に配置されるとともに第２前側リング部に固定され且つ第２前側ガスバーナが挿し通される第２前側板状部材と、第２前側リング部と第２前側板状部材とを連結する第２前側連結部材と、を有する第２前側内枠部（中央側内枠部６２）を備えている。そして、第６補強部材８６，８７は、第１前側板状部材と第２前側板状部材との間の領域において第１前側板状部材寄りに配置される第１梁部材と、第１前側板状部材と第２前側板状部材との間の領域において第２前側板状部材寄りに配置される第２梁部材と、を有している。このようにすれば、変形が特に懸念される第１前側内枠部と第２前側内枠部の間の領域において、軽量化を図りつつ前後方向の強度を一層高め得る構成を効率的に組み込むことができる。   Further, the gas stove 1 has an annular shape arranged along the first front opening 21A, and at least a part of the gas stove 1 covers the upper surface of the top plate body 20 around the first front opening 21A.
