Description

本発明は、加熱調理器に関する。   The present invention relates to a cooking device.

従来、器具本体の上面開口を覆う天板に設けた開口部から、器具本体側に設けたバーナを上方に突出して配置するガスコンロが知られている。天板は、鋼板の表面にホーロー処理を施して形成される。ホーロー処理の過程において、天板の外周縁部には釉薬が溜まりやすい。ゆえに天板は、焼成によって固まった釉薬の溜まり(いわゆるホーロー溜まり)が外周縁部に形成される場合がある。   2. Description of the Related Art Conventionally, there has been known a gas stove in which a burner provided on the instrument body side protrudes upward from an opening provided on a top plate that covers an upper surface opening of the instrument body. The top plate is formed by performing enamel treatment on the surface of the steel plate. During the enamel process, glaze tends to accumulate on the outer peripheral edge of the top board. Therefore, the top plate may have a glaze pool (so-called enamel pool) hardened by firing at the outer peripheral edge.

ところで、天板の外周縁部に沿って外枠を設けたガスコンロが知られている(例えば、特許文献1参照)。天板は、加熱調理器の使用によって受熱すると、反りを生ずる可能性がある。特許文献1に記載の加熱調理器は、外枠の上端側で突設する庇部が天板の上面に当接する構成であり、庇部が外周縁部を下方に向けて押さえるので天板の反りを抑制できる。また、外枠は、天板の外周縁部に形成されたホーロー溜まりを覆い隠すことができ、天板の美観も損ねない。   By the way, the gas stove which provided the outer frame along the outer-periphery edge part of a top plate is known (for example, refer patent document 1). When the top plate receives heat through the use of a heating cooker, it may warp. The heating cooker described in Patent Document 1 has a configuration in which a collar portion protruding from the upper end side of the outer frame abuts on the upper surface of the top plate, and the collar portion presses the outer peripheral edge downward, so that the top plate Warpage can be suppressed. Further, the outer frame can cover the enamel pool formed on the outer peripheral edge of the top plate, and the aesthetic appearance of the top plate is not impaired.

As shown in FIG. 2, the top plate 3 includes a top plate 21 and a rear plate 22. As described above, the top plate 21 has the burner openings 24 to 26 formed in the flat steel plate 21A (see FIG. 4), and in this embodiment, the front and back surfaces are subjected to enamel treatment to provide the glass coat layer 21B (FIG. 4). It is a plate body formed with a reference). The formation positions of the burner openings 24 to 26 correspond to the arrangement positions of the right burner 4, the left burner 5, and the back burner 6 (see FIG. 1) provided in the instrument body 2, respectively. The burner openings 24 to 26 have a circular shape in a plan view, and have an inner diameter larger than the outer diameter of each burner head of the right burner 4, the left burner 5, and the back burner 6.

カバーリング34〜36はそれぞれ短軸で筒状に形成され、軸方向をトッププレート21の厚み方向に合わせてトッププレート21に組み付けられる部材である。カバーリング34〜36は、軸方向一端部が径方向外向きに鍔状に延び、天板3を器具本体2に組み付けた場合に器具本体2とは反対側(上側)を向く面(以下、「天面」3Aという。)側で、それぞれバーナ開口24〜26の縁部を覆う。また、カバーリング34〜36は、軸方向他端部が、天面3Aとは反対側(下側)の面(以下、「裏面」3B(図3参照)という。)側に設けた押さえ板37,38,39(図3参照)にそれぞれ固定されて、トッププレート21に組み付けられている。   Each of the cover rings 34 to 36 is a member that is formed in a cylindrical shape with a short axis, and is assembled to the top plate 21 with the axial direction aligned with the thickness direction of the top plate 21. The cover rings 34 to 36 each have one end in the axial direction extending radially outwardly in a bowl shape, and faces the opposite side (upper side) of the instrument body 2 when the top plate 3 is assembled to the instrument body 2 (hereinafter, referred to as the cover rings 34 to 36). On the “top surface” 3A) side, the edges of the burner openings 24 to 26 are respectively covered. Further, the cover rings 34 to 36 have a pressing plate provided at the other end in the axial direction on the side opposite to the top surface 3A (hereinafter referred to as “back surface” 3B (see FIG. 3)). 37, 38 and 39 (see FIG. 3), respectively, and assembled to the top plate 21.

後板22は、前述したように、左右方向を長手方向とする長方形状でアルミニウム製の板体である。後板22は、排気口7の左右両端に、前後方向に延びる長穴状のガイド穴(図示略)と、ガイド穴に挿入された操作ネジ23を備える。操作ネジ23は、先端部が、天板3を器具本体2に固定するため天板3の裏面3B側に設けられる一対の固定板71(図3参照)にねじ込まれている。操作ネジ23は、固定板71をガイド穴に沿って前後方向に移動でき、且つ、ねじ締めすることで、天板3に固定板71を位置決めすることができる。   As described above, the rear plate 22 is a rectangular aluminum plate having the left-right direction as the longitudinal direction. The rear plate 22 includes elongated hole-shaped guide holes (not shown) extending in the front-rear direction and operation screws 23 inserted into the guide holes at the left and right ends of the exhaust port 7. The operation screw 23 is screwed into a pair of fixing plates 71 (see FIG. 3) provided on the back surface 3B side of the top plate 3 in order to fix the top plate 3 to the instrument body 2. The operation screw 23 can move the fixing plate 71 in the front-rear direction along the guide hole, and can position the fixing plate 71 on the top plate 3 by screwing.

図3を参照し、天板3の裏面3B側の構成について説明する。なお、図3は、図2に示す天板3を裏返して裏面3Bを上方へ向けた状態の斜視図であるが、説明の便宜上、図3においても図2の方向の定義に準じて説明する。天板3は、裏面3Bに金属製の下板30を備える。下板30は、裏面3B側でトッププレート21および後板22と向き合って配置される。下板30は、排気口7およびバーナ開口24〜26の部分が開口されている。トッププレート21は下板30に接着剤で固定され、後板22は下板30にネジ止めされており、トッププレート21と後板22とが下板30を介して互いに位置決めされる。   With reference to FIG. 3, the structure of the back surface 3B side of the top plate 3 will be described. 3 is a perspective view of the state in which the top plate 3 shown in FIG. 2 is turned upside down and the back surface 3B is directed upward. However, for convenience of explanation, FIG. 3 is also explained according to the definition of the direction of FIG. . The top plate 3 includes a metal lower plate 30 on the back surface 3B. The lower plate 30 is disposed facing the top plate 21 and the rear plate 22 on the back surface 3B side. The lower plate 30 is opened at portions of the exhaust port 7 and the burner openings 24 to 26. The top plate 21 is fixed to the lower plate 30 with an adhesive, the rear plate 22 is screwed to the lower plate 30, and the top plate 21 and the rear plate 22 are positioned with respect to each other via the lower plate 30.

また、下板30は、バーナ開口24,25の前側の位置、バーナ開口24,25とバーナ開口26との間の位置、およびバーナ開口26と排気口7との間の位置のそれぞれに、下方へ向けて立ち上がり、且つ左右方向に延びるリブ30Aを有する。リブ30Aは、下板30に設けた切欠部を折り曲げて形成されたものであり、下板30の機械的強度を高める。下板30は、トッププレート21および後板22を下支えして補強する。さらに下板30は、接着剤を介してトッププレート21に密着することで、トッププレート21が各種バーナ4〜6の燃焼熱によって部分的に受熱した熱を拡散し、熱によるトッププレート21の歪みを防止する。後述するが、下板30の前後方向における縁端部30C(図5参照)は天板3の縁部42Aと重なる位置に配置され、左右方向における縁端部30B(図4参照)は、天板3の縁部41Aよりも天板3の内方側の位置に配置される。また、上記した押さえ板37〜39は、それぞれ下板30に位置決められて固定されている。   Further, the lower plate 30 is positioned below the burner openings 24 and 25, the position between the burner openings 24 and 25 and the burner opening 26, and the position between the burner opening 26 and the exhaust port 7. And a rib 30A extending in the left-right direction. The ribs 30 </ b> A are formed by bending notches provided in the lower plate 30 and increase the mechanical strength of the lower plate 30. The lower plate 30 supports and reinforces the top plate 21 and the rear plate 22. Further, the lower plate 30 is brought into close contact with the top plate 21 via an adhesive, whereby the top plate 21 diffuses the heat partially received by the combustion heat of the various burners 4 to 6, and the distortion of the top plate 21 due to the heat. To prevent. As will be described later, the edge 30C (see FIG. 5) in the front-rear direction of the lower plate 30 is disposed at a position overlapping the edge 42A of the top plate 3, and the edge 30B (see FIG. 4) in the left-right direction is It arrange | positions in the position of the inner side of the top plate 3 rather than the edge part 41A of the plate 3. FIG. Further, the pressing plates 37 to 39 described above are positioned and fixed to the lower plate 30, respectively.

天板3は、裏面3Bの左端側および右端側に、前後方向に延びる一対の板状の固定板71を備える。前述したように、固定板71は天板3を器具本体2に固定するための板体である。固定板71は、天板3の取り付けまたは取り外しの際に前後方向へスライド移動できるように、下板30によって支持される。後述するフレーム部材51は、一部が、上下方向において固定板71と下板30との間に配置される。固定板71は前方側の端部がL字状に曲がって内向きに延び、その先端に、前方へ向けて突出する突片71Aを備える。天板3を器具本体2に固定する場合、作業者が操作ネジ23を操作することで、突片71Aは、器具本体2の前枠に設けられた穴部(図示略)に係合する。   The top plate 3 includes a pair of plate-like fixing plates 71 extending in the front-rear direction on the left end side and the right end side of the back surface 3B. As described above, the fixing plate 71 is a plate for fixing the top plate 3 to the instrument body 2. The fixed plate 71 is supported by the lower plate 30 so as to be slidable in the front-rear direction when the top plate 3 is attached or detached. A part of the frame member 51 described later is disposed between the fixed plate 71 and the lower plate 30 in the vertical direction. The fixed plate 71 is provided with a projecting piece 71A that protrudes forward at the tip thereof, with its front end bent in an L shape and extends inward. When the top plate 3 is fixed to the instrument main body 2, the projecting piece 71 </ b> A engages with a hole (not shown) provided in the front frame of the instrument main body 2 by operating the operation screw 23.

天板3は、四つの辺に、左右の縁部41Aおよび前後の縁部42Aをそれぞれ裏面3B側で内向きに返した返し部41および42(図4〜図6参照)を有する。言い換えると、トッププレート21の前方側および左右両側の縁部と、後板22の左右両側および後方側の縁部は、裏面3B側で内向きに返されている。図4〜図6に示すように、返し部41,42はそれぞれ断面が円弧状に返されている。天面3Aは、返し部41,42においては面の向く方向(面方向)が天板3の側方を向き、縁部41A,42Aにおいては面方向が下方を向く。裏面3Bは、返し部41,42においては面方向が天板3の内方を向き、縁部41A,42Aにおいては面方向が上方を向いて、天板3の本体部(返し部41,42および後述する返し部45を除く部分)における裏面3Bと向き合う。そして縁部41A,42Aの端面は、面方向が天板3の内方を向く。ゆえに、縁部41A,42Aは側方から視認できない。   The top plate 3 has return portions 41 and 42 (refer to FIGS. 4 to 6) on the four sides, in which the left and right edge portions 41 </ b> A and the front and rear edge portions 42 </ b> A are returned inward on the back surface 3 </ b> B side. In other words, the front and left and right edges of the top plate 21 and the left and right and rear edges of the rear plate 22 are returned inward on the back surface 3B side. As shown in FIGS. 4 to 6, each of the return portions 41 and 42 is returned in an arc shape in cross section. In the top surface 3A, the direction of the surface (surface direction) in the return portions 41 and 42 faces the side of the top plate 3, and the surface direction in the edge portions 41A and 42A faces downward. The back surface 3B has a surface direction facing the inside of the top plate 3 at the return portions 41 and 42, and a surface direction facing upward at the edge portions 41A and 42A. And the back surface 3B in the portion excluding the return portion 45 described later). The end surfaces of the edge portions 41 </ b> A and 42 </ b> A are directed inward of the top plate 3. Therefore, the edges 41A and 42A are not visible from the side.

また、天板3は、四つの角部45Aをそれぞれ裏面3B側で内向きに返した返し部45(図7参照)を有する。言い換えると、トッププレート21の前方側の角部と、後板22の後方側の角部は、裏面3B側で内向きに返されている。図7に示すように、返し部45も同様に、断面が円弧状に返されている。天面3Aは、返し部45においては面方向が天板3の側方を向き、角部45Aにおいては面方向が下方を向く。裏面3Bも同様に、返し部45においては面方向が天板3の内方を向き、角部45Aにおいては面方向が上方を向いて、天板3の本体部における裏面3Bと向き合う。そして角部45Aの端面は、面方向が天板3の内方を向く。よって、角部45Aも側方から視認できない。このように、返し部41,42,45が天板3の周方向に連続して設けられることによって、天板3は、側方の縁が周方向の一周に亘って滑らかな曲面で構成される。   Moreover, the top plate 3 has return portions 45 (see FIG. 7) that return the four corner portions 45A inward on the back surface 3B side. In other words, the front corner of the top plate 21 and the rear corner of the rear plate 22 are returned inward on the back surface 3B side. As shown in FIG. 7, the return portion 45 is similarly returned in an arc shape in cross section. The top surface 3A has a surface direction facing the side of the top plate 3 at the turn-back portion 45, and a surface direction facing downward at the corner portion 45A. Similarly, the back surface 3B faces the back surface 3B of the main body of the top plate 3 with the surface direction facing the inside of the top plate 3 at the turn portion 45 and the surface direction facing upward at the corner portion 45A. The end surface of the corner portion 45 </ b> A is directed inward of the top plate 3. Therefore, the corner portion 45A is not visible from the side. Thus, by providing the return portions 41, 42, 45 continuously in the circumferential direction of the top plate 3, the top plate 3 is configured with a smooth curved surface over one circumference in the circumferential direction. The

図3に示すように、天板3は、裏面3Bに、返し部41,42および45それぞれの縁部41A,42Aおよび角部45A(図4,図5,図7参照)をそれぞれ保持するためのフレーム部材51,52および55を備える。図4,図5に示すフレーム部材51,52は、それぞれ下板30に固定され、下板30とともに、天板3の縁部41A,42Aを位置決めして保持する。また、図7に示すフレーム部材55は、下板30に固定されるフレーム部材51,52を介して下板30に固定され、天板3の角部45Aを保持する。   As shown in FIG. 3, the top plate 3 holds the edge portions 41A, 42A and the corner portions 45A (see FIGS. 4, 5, and 7) of the return portions 41, 42, and 45 on the back surface 3B, respectively. Frame members 51, 52 and 55. The frame members 51 and 52 shown in FIGS. 4 and 5 are respectively fixed to the lower plate 30 and, together with the lower plate 30, position and hold the edges 41 </ b> A and 42 </ b> A of the top plate 3. Further, the frame member 55 shown in FIG. 7 is fixed to the lower plate 30 via frame members 51 and 52 fixed to the lower plate 30, and holds the corners 45 </ b> A of the top plate 3.

図3,図4,図6に示すように、フレーム部材51は、アルミニウムまたはアルミニウム合金からなる細幅な板状の部材である。フレーム部材51は、長手方向を前後方向に揃え、厚み方向を上下方向に向けて天板3の裏面3Bに取り付けられる。   As shown in FIGS. 3, 4, and 6, the frame member 51 is a narrow plate-like member made of aluminum or an aluminum alloy. The frame member 51 is attached to the back surface 3B of the top plate 3 with the longitudinal direction aligned in the front-rear direction and the thickness direction directed in the up-down direction.

図4,図6に示すように、フレーム部材51は、保持部51A、固定部51B、連結部51C、貼設部51Dおよび放熱部51Eを備える。保持部51Aは、返し部41の縁部41Aを保持する部位であり、フレーム部材51を構成する長手側の二辺のうちの一辺に、長手方向の全長に亘って設けられる。保持部51Aは、フレーム部材51の厚み方向において所定間隙を離し、互いに向き合って配置される2つの対向部511,512を備える。フレーム部材51が下板30に固定された場合に、対向部511は返し部41の縁部41Aに対して下方に配置され、縁部41Aにおいて面方向が下方を向く天面3Aと向き合う。同様に対向部512は縁部41Aに対して上方に配置され、縁部41Aにおいて面方向が上方を向く裏面3Bと向き合う。前述したように、下板30は、左右方向両側の縁端部30Bが保持部51Aの形成位置(言い換えると返し部42の内面側の位置)よりも天板3の内方側に位置する。このため、下板30の縁端部30Bと天板3の裏面3Bとの間に生じる段差によって、縁部41Aの端面と縁端部30Bの端面を縁とし、天板3の左右側の辺に沿って延びる溝部3Cが形成される。フレーム部材51は、天板3に取り付ける場合に、対向部511,512間に縁部41Aを挟むため、保持部51Aを斜めに傾けて縁部41Aに差し込む。このとき、対向部512は溝部3C内に逃げることができ、下板30に干渉しない。さらに、対向部511,512間に縁部41Aを差し込んだ状態で、縁部41Aを支点にフレーム部材51を回転させ、対向部511,512間の奥まで縁部41Aが配置されるようにスライドすることで、フレーム部材51を取り付け位置に配置する。このとき、溝部3Cが保持部51Aの位置決めとなってフレーム部材51の回転およびスライドを案内するので、フレーム部材51の下板30への取り付けを容易に行うことができる。   As shown in FIGS. 4 and 6, the frame member 51 includes a holding part 51A, a fixing part 51B, a connecting part 51C, a pasting part 51D, and a heat radiating part 51E. The holding portion 51 </ b> A is a portion that holds the edge portion 41 </ b> A of the return portion 41, and is provided on one side of the two long sides constituting the frame member 51 over the entire length in the longitudinal direction. The holding portion 51 </ b> A includes two facing portions 511 and 512 that are arranged to face each other with a predetermined gap in the thickness direction of the frame member 51. When the frame member 51 is fixed to the lower plate 30, the facing portion 511 is disposed below the edge portion 41A of the return portion 41, and faces the top surface 3A whose surface direction faces downward at the edge portion 41A. Similarly, the facing portion 512 is disposed above the edge portion 41A, and faces the back surface 3B with the surface direction facing upward at the edge portion 41A. As described above, in the lower plate 30, the edge portions 30B on both sides in the left-right direction are positioned on the inner side of the top plate 3 from the position where the holding portion 51A is formed (in other words, the position on the inner surface side of the return portion 42). For this reason, the step formed between the edge portion 30B of the lower plate 30 and the back surface 3B of the top plate 3 has the end surface of the edge portion 41A and the end surface of the edge end portion 30B as edges, and the left and right sides of the top plate 3 A groove 3 </ b> C extending along the line is formed. When the frame member 51 is attached to the top plate 3, the holding part 51 </ b> A is inclined and inserted into the edge part 41 </ b> A in order to sandwich the edge part 41 </ b> A between the facing parts 511 and 512. At this time, the facing portion 512 can escape into the groove 3 </ b> C and does not interfere with the lower plate 30. Further, in a state where the edge 41A is inserted between the facing portions 511 and 512, the frame member 51 is rotated with the edge 41A as a fulcrum, and the edge 41A is slid so that the edge 41A is disposed deeply between the facing portions 511 and 512. As a result, the frame member 51 is arranged at the attachment position. At this time, since the groove 3C is positioned by the holding portion 51A and guides the rotation and slide of the frame member 51, the frame member 51 can be easily attached to the lower plate 30.

対向部511と対向部512との間の間隙は、縁部41Aにおける天板3の厚みよりも大きく形成されている。トッププレート21はホーロー処理が施されるため、縁部41Aにホーロー溜まりを生ずる場合がある。保持部51Aは、ホーロー溜まりによって縁部41Aの厚みが増しても、天板3の厚みよりも大きく形成した対向部511,512の間隙に、縁部41Aを配置することができる。また、天板3が自重によって縁部41Aを下方に押しつけるので、縁部41Aは、下側に配置される対向部511と密接する。ゆえに、側方から保持部51A内をのぞき込んでも縁部41Aひいてはホーロー溜まりを視認することはできず、返し部41を備えたことによる天板3の美観は損なわれない。   The gap between the facing portion 511 and the facing portion 512 is formed larger than the thickness of the top plate 3 at the edge portion 41A. Since the top plate 21 is subjected to enamel processing, enamel accumulation may occur at the edge 41A. Even if the thickness of the edge portion 41A is increased by the enamel pool, the holding portion 51A can arrange the edge portion 41A in the gap between the facing portions 511 and 512 formed larger than the thickness of the top plate 3. Moreover, since the top plate 3 presses the edge portion 41A downward by its own weight, the edge portion 41A is in close contact with the facing portion 511 disposed on the lower side. Therefore, even if the inside of the holding portion 51A is looked into from the side, the edge portion 41A and thus the enamel pool cannot be visually recognized, and the aesthetic appearance of the top board 3 provided with the return portion 41 is not impaired.

固定部51Bは、フレーム部材51を下板30に固定する部位であり、例えば厚み方向に貫通する貫通穴513を備え、フレーム部材51の幅方向(短手方向)略中央で、長手方向の複数箇所(例えば2カ所)に設けられる。下板30は、固定部51Bに対応する位置にネジ穴30Dを有する。止めネジ59(図4参照)を貫通穴513に挿通した状態でネジ穴30Dに締結することで、フレーム部材51は下板30に固定される。すなわち、天板3の縁部41Aは、フレーム部材51を介し、下板30に位置決めされる。   The fixing part 51B is a part that fixes the frame member 51 to the lower plate 30, and includes, for example, a through hole 513 that penetrates in the thickness direction, at a substantially center in the width direction (short direction) of the frame member 51, and a plurality of longitudinal directions. It is provided at a location (for example, 2 locations). The lower plate 30 has a screw hole 30D at a position corresponding to the fixing portion 51B. The frame member 51 is fixed to the lower plate 30 by fastening the set screw 59 (see FIG. 4) to the screw hole 30 </ b> D in a state where the set screw 59 is inserted into the through hole 513. That is, the edge 41 </ b> A of the top plate 3 is positioned on the lower plate 30 through the frame member 51.

連結部51Cは、フレーム部材51がフレーム部材55(後述)と連結するための部位であり、フレーム部材51の長手方向両端にそれぞれ設けられる。連結部51Cには、フレーム部材55が備える突起部553(図6参照)に係合する係合穴514が設けられている。フレーム部材51は連結部51Cにおいて天板3との間にフレーム部材55の連結部55B(図6参照)を挟み、フレーム部材55と密着して熱を伝導できるようにする。係合穴514は、突起部553と係合することで、フレーム部材51とフレーム部材55との連結位置を位置決めする。   The connecting portions 51 </ b> C are portions for connecting the frame member 51 to a frame member 55 (described later), and are provided at both ends in the longitudinal direction of the frame member 51. 51 C of coupling parts are provided with the engagement hole 514 engaged with the projection part 553 (refer FIG. 6) with which the frame member 55 is provided. The frame member 51 sandwiches the connecting portion 55B (see FIG. 6) of the frame member 55 between the top portion 3 and the connecting portion 51C so as to be in close contact with the frame member 55 and conduct heat. The engagement hole 514 is engaged with the protrusion 553 to position the connection position between the frame member 51 and the frame member 55.

貼設部51Dは、保持部51Aにおける対向部511の下側の面と、対向部511の縁を下方へ折り返した縁曲げ部519の内側の面によって構成される部位であり、パッキン29が位置決めされて貼り付けられる。パッキン29は、コンロ1をキッチンのカウンタートップに設置した場合に、カウンタートップと天板3との間に介在してカウンタートップの傷付きを防止し、且つ、吹きこぼれ等がコンロ1内に進入するのを防ぐ。   The affixing part 51D is a part constituted by a lower surface of the facing part 511 in the holding part 51A and an inner surface of an edge bending part 519 where the edge of the facing part 511 is folded downward, and the packing 29 is positioned. And pasted. When the stove 1 is installed on the counter top of the kitchen, the packing 29 is interposed between the counter top and the top plate 3 to prevent the counter top from being damaged, and spillage or the like enters the stove 1. To prevent.

なお、対向部511は、上側の面が、縁曲げ部519における外側の面へ向けて連続して滑らかな曲面を構成するように形成されており、エッジがない。縁曲げ部519は、保持部51Aが天板3の縁部41Aを保持した場合に、返し部41よりも天板3の内方側に位置するように、対向部511に設けられている。そして、天板3の縁部41Aが対向部511と当接する位置において、返し部41における天面3Aが構成する曲面と、縁曲げ部519における曲面とが合流する。ゆえに、天板3を側方(特に斜め上方)からみた場合に、縁曲げ部519は返し部41によって視線が遮られ、目立ちにくい。また、曲面構成する返し部41と同様に縁曲げ部519も曲面を構成してエッジをなくすことによって、縁曲げ部519が返し部41よりも目立つことがない。そして、縁曲げ部519が後述する縁曲げ部529,559とともに天板3の下側で天板3の縁に沿って一周して配置されることで、天板3が縁取りされる視覚効果を得ることができる。よって、天板3自体の存在感を際立たせることができ、美観向上を図ることができる。   The facing portion 511 is formed so that the upper surface continuously forms a smooth curved surface toward the outer surface of the edge bent portion 519, and has no edge. The edge bending portion 519 is provided in the facing portion 511 so as to be located on the inner side of the top plate 3 with respect to the return portion 41 when the holding portion 51A holds the edge portion 41A of the top plate 3. Then, the curved surface formed by the top surface 3A of the return portion 41 and the curved surface of the edge bent portion 519 merge at a position where the edge portion 41A of the top plate 3 contacts the facing portion 511. Therefore, when the top plate 3 is viewed from the side (especially obliquely upward), the edge bending portion 519 is blocked by the return portion 41 and is less noticeable. Similarly to the curved portion 41, the edge bent portion 519 also forms a curved surface and eliminates the edge, so that the edge bent portion 519 does not stand out more than the curved portion 41. And the edge bending part 519 and the edge bending parts 529 and 559 which will be described later are arranged around the edge of the top board 3 on the lower side of the top board 3 so that the visual effect that the top board 3 is trimmed is obtained. Can be obtained. Therefore, the presence of the top plate 3 itself can be emphasized, and the aesthetics can be improved.

放熱部51Eは、フレーム部材51が受熱した熱を放熱するための部位であり、フレーム部材51を構成する長手側の二辺のうち固定部51Bを挟んで保持部51Aとは反対側の辺側に設けられる。放熱部51Eは、板面から下方へ向けてリブ状に立設し、長手方向に沿って延びる二本の板状体によって構成される。放熱部51Eはフレーム部材51の表面積を増やし、フレーム部材51の熱を放熱する。また、放熱部51Eは、リブ構造によって、フレーム部材51の強度を補強する。   The heat dissipating part 51E is a part for dissipating the heat received by the frame member 51. Of the two sides on the long side constituting the frame member 51, the side opposite to the holding part 51A across the fixing part 51B Is provided. The heat radiating portion 51E is configured by two plate-like bodies that stand in a rib shape downward from the plate surface and extend along the longitudinal direction. The heat radiating part 51E increases the surface area of the frame member 51 and radiates the heat of the frame member 51. Moreover, the heat radiating part 51E reinforces the strength of the frame member 51 by a rib structure.

フレーム部材51は、上記のように保持部51Aが2つの対向部511,512を備える構造である。ゆえに、フレーム部材51を下板30へ取り付ける場合、前述したように、保持部51A側に対して放熱部51E側を天板3の裏面3Bから遠ざけた状態にフレーム部材51を傾け、天板3の縁部41Aを対向部511,512間に配置する。対向部511よりも天板3側に位置する対向部512は、天板3の溝部3C内に逃げ、下板30に干渉しない。その状態で保持部51Aを支点にフレーム部材51を回転させて放熱部51E側を裏面3Bに近づける。さらに対向部511,512間に縁部41Aが配置されるようにスライドすることで、フレーム部材51を取り付け位置に配置する。溝部3Cは、保持部51Aの位置決めとなってフレーム部材51の回転およびスライドを案内する。固定部51Bの貫通穴513に挿通した止めネジ59を下板30のネジ穴30Dに締結し、フレーム部材51を下板30に固定する。天板3の縁部41Aは、フレーム部材51のスライドによって対向部511,512のほぼ全面と向き合って配置されるので、止めネジ59によってフレーム部材51のスライドが規制されることで、保持部51Aから外れにくい。天板3は、フレーム部材51によって、前後方向に沿う辺を構成する部分において縁部41Aの位置決めと保持がなされ、受熱による天板3の反りが防止される。   The frame member 51 has a structure in which the holding portion 51A includes the two facing portions 511 and 512 as described above. Therefore, when attaching the frame member 51 to the lower plate 30, as described above, the frame member 51 is tilted so that the heat radiating portion 51E side is away from the back surface 3B of the top plate 3 with respect to the holding portion 51A side. The edge portion 41A is disposed between the facing portions 511 and 512. The facing portion 512 located closer to the top plate 3 than the facing portion 511 escapes into the groove 3 </ b> C of the top plate 3 and does not interfere with the lower plate 30. In this state, the frame member 51 is rotated with the holding portion 51A as a fulcrum, and the heat radiating portion 51E side is brought closer to the back surface 3B. Further, the frame member 51 is disposed at the attachment position by sliding so that the edge portion 41A is disposed between the facing portions 511 and 512. The groove portion 3C guides the rotation and sliding of the frame member 51 by positioning the holding portion 51A. The set screw 59 inserted through the through hole 513 of the fixing portion 51B is fastened to the screw hole 30D of the lower plate 30 to fix the frame member 51 to the lower plate 30. Since the edge portion 41A of the top plate 3 is disposed so as to face almost the entire surface of the facing portions 511 and 512 by the slide of the frame member 51, the slide of the frame member 51 is regulated by the set screw 59, whereby the holding portion 51A. Hard to come off. The top plate 3 is positioned and held by the frame member 51 at the portion constituting the side along the front-rear direction, and the warp of the top plate 3 due to heat reception is prevented.

次に、図3,図5,図6に示すように、フレーム部材52は、フレーム部材51同様に、アルミニウムまたはアルミニウム合金からなる細幅な板状の部材である。フレーム部材52は、長手方向を左右方向に揃え、厚み方向を上下方向に向けて天板3の裏面3Bに取り付けられる。   Next, as shown in FIGS. 3, 5, and 6, the frame member 52 is a narrow plate-like member made of aluminum or an aluminum alloy, like the frame member 51. The frame member 52 is attached to the back surface 3B of the top plate 3 with the longitudinal direction aligned in the left-right direction and the thickness direction directed in the up-down direction.

図5,図6に示すように、フレーム部材52は、保持部52A、固定部52B、連結部52C、および貼設部51Dを備える。保持部52Aは、返し部42の縁部42Aを保持する部位であり、上記同様、フレーム部材52を構成する長手側の二辺のうちの一辺に、長手方向の全長に亘って設けられる。保持部52Aは、フレーム部材52が下板30に固定された場合に、返し部42の縁部42Aに対して下方に配置されるように段状に形成され、縁部42Aにおいて面方向が下方を向く天面3Aと向き合う対向部521を備える。前述したように、下板30は、前後方向両側の縁端部30Cが、縁部42Aと重なる位置(言い換えると返し部42の内面側の位置)に配置されている。保持部52Aの対向部521と、下板30の縁端部30Cとは、フレーム部材52の厚み方向において所定間隙を離し、互いに向き合って配置される。対向部521は返し部42の縁部42Aに対して下方に配置され、縁部42Aにおいて面方向が下方を向く天面3Aと向き合う。下板30の縁端部30Cは縁部42Aに対して上方に配置され、縁部42Aにおいて面方向が上方を向く裏面3Bと向き合う。   As shown in FIGS. 5 and 6, the frame member 52 includes a holding portion 52A, a fixing portion 52B, a connecting portion 52C, and a pasting portion 51D. The holding portion 52 </ b> A is a portion that holds the edge portion 42 </ b> A of the return portion 42, and is provided on one side of the two long sides constituting the frame member 52 over the entire length in the longitudinal direction. When the frame member 52 is fixed to the lower plate 30, the holding portion 52 </ b> A is formed in a step shape so as to be disposed below the edge portion 42 </ b> A of the return portion 42, and the surface direction of the edge portion 42 </ b> A is downward. And a facing portion 521 facing the top surface 3A. As described above, the lower plate 30 is disposed at a position where the edge portions 30C on both sides in the front-rear direction overlap with the edge portion 42A (in other words, a position on the inner surface side of the return portion 42). The facing portion 521 of the holding portion 52A and the edge portion 30C of the lower plate 30 are arranged facing each other with a predetermined gap in the thickness direction of the frame member 52. The facing portion 521 is disposed below the edge portion 42A of the return portion 42, and faces the top surface 3A whose surface direction faces downward at the edge portion 42A. The edge portion 30C of the lower plate 30 is disposed above the edge portion 42A, and faces the back surface 3B with the surface direction facing upward at the edge portion 42A.

対向部521と縁端部30Cとの間の間隙も、上記同様、ホーロー溜まりによって縁部42Aの厚みが増しても間に配置できるように、縁部42Aにおける天板3の厚みよりも大きく形成されている。そして、天板3が自重によって縁部42Aを下方に押しつけるので、縁部42Aは、下側に配置される対向部521と密接する。ゆえに、側方から保持部52A内をのぞき込んでも縁部42Aひいてはホーロー溜まりを視認することはできず、返し部42を備えたことによる天板3の美観は損なわれない。   Similarly to the above, the gap between the facing portion 521 and the edge portion 30C is formed larger than the thickness of the top plate 3 at the edge portion 42A so that it can be disposed even if the thickness of the edge portion 42A increases due to the enamel pool. Has been. And since the top plate 3 presses the edge part 42A downward by its own weight, the edge part 42A comes into close contact with the facing part 521 arranged on the lower side. Therefore, even if the inside of the holding part 52A is looked into from the side, the edge part 42A and thus the enamel pool cannot be visually recognized, and the aesthetic appearance of the top board 3 provided with the return part 42 is not impaired.

固定部52Bは、フレーム部材52を下板30に固定する部位である。固定部52Bは厚み方向に貫通する貫通穴523(図5参照)を備え、フレーム部材52を構成する長手側の二辺のうち保持部52Aとは反対側の辺側で、長手方向の複数箇所(例えば3カ所)に設けられる。貫通穴523に挿通した止めネジ59(図5参照)を下板30に設けたネジ穴30Dに締結することで、フレーム部材52は下板30に固定される。すなわち、上記同様、天板3の縁部42Aも、フレーム部材52を介し、下板30に位置決めされる。   The fixing part 52 </ b> B is a part that fixes the frame member 52 to the lower plate 30. The fixing portion 52B includes a through hole 523 (see FIG. 5) penetrating in the thickness direction, and a plurality of longitudinal portions on the side opposite to the holding portion 52A among the two long sides constituting the frame member 52. (For example, at three locations). The frame member 52 is fixed to the lower plate 30 by fastening a set screw 59 (see FIG. 5) inserted through the through hole 523 into a screw hole 30 </ b> D provided in the lower plate 30. That is, as described above, the edge portion 42 </ b> A of the top plate 3 is also positioned on the lower plate 30 via the frame member 52.

連結部52Cは、フレーム部材52がフレーム部材55(後述)と連結するための部位であり、フレーム部材52の長手方向両側の端部にそれぞれ設けられる。図6に示すように、連結部52Cには、フレーム部材55の突起部554に係合する係合穴524と、フレーム部材55に設けられたネジ穴555に締結する止めネジ556を挿通可能な挿通穴525が設けられている。連結部52Cを介してフレーム部材51がフレーム部材55の連結部55Cを天板3との間に挟み、フレーム部材55と密着して熱を伝導できるようにする点は上記同様である。係合穴524は、突起部554と係合することで、フレーム部材52とフレーム部材55との連結位置を位置決めする。挿通穴525は、止めネジ556ネジ止めによって、フレーム部材52とフレーム部材55とを固定する。   The connecting portions 52 </ b> C are portions for connecting the frame member 52 to a frame member 55 (described later), and are provided at both ends of the frame member 52 in the longitudinal direction. As shown in FIG. 6, an engaging hole 524 that engages with the protrusion 554 of the frame member 55 and a set screw 556 that is fastened to a screw hole 555 provided in the frame member 55 can be inserted into the connecting portion 52 </ b> C. An insertion hole 525 is provided. The point that the frame member 51 sandwiches the connecting portion 55C of the frame member 55 between the top plate 3 through the connecting portion 52C and is in close contact with the frame member 55 so that heat can be conducted is the same as described above. The engagement hole 524 is engaged with the protrusion 554 to position the connection position between the frame member 52 and the frame member 55. The insertion hole 525 fixes the frame member 52 and the frame member 55 by fastening a set screw 556.

貼設部52Dは、保持部52Aにおける対向部521の下側の面と、対向部521の縁を下方へ折り返した縁曲げ部529の内側の面によって構成される部位であり、前述のパッキン29が位置決めされて貼り付けられる。なお、対向部521も、上側の面が、縁曲げ部529における外側の面へ向けて連続して滑らかな曲面を構成するように形成されており、エッジがない。上記同様、縁曲げ部529は、保持部52Aが天板3の縁部42Aを保持した場合に、返し部42よりも天板3の内方側に位置するように、対向部521に設けられている。そして、天板3の縁部42Aが対向部521と当接する位置において、返し部42における天面3Aが構成する曲面と、縁曲げ部529における曲面とが合流する。ゆえに、天板3を側方(特に斜め上方)からみた場合に、縁曲げ部529は返し部42によって視線が遮られ、目立ちにくい。また、曲面構成する返し部42と同様に縁曲げ部529も曲面を構成してエッジをなくすことによって、縁曲げ部529が返し部42よりも目立つことがない。そして、縁曲げ部529が縁曲げ部519と、後述する縁曲げ部559とともに天板3の下側で天板3の縁に沿って一周して配置されることで、天板3が縁取りされる視覚効果を得ることができる。よって、天板3自体の存在感を際立たせることができ、美観向上を図ることができる。   The affixing portion 52D is a portion configured by a lower surface of the facing portion 521 in the holding portion 52A and an inner surface of the edge bending portion 529 where the edge of the facing portion 521 is folded downward. Is positioned and pasted. Note that the facing portion 521 is also formed so that the upper surface continuously forms a smooth curved surface toward the outer surface of the edge bent portion 529 and has no edge. Similarly to the above, the edge bending portion 529 is provided in the facing portion 521 so as to be positioned on the inner side of the top plate 3 with respect to the return portion 42 when the holding portion 52A holds the edge portion 42A of the top plate 3. ing. Then, the curved surface formed by the top surface 3 </ b> A of the return portion 42 and the curved surface of the edge bent portion 529 merge at a position where the edge portion 42 </ b> A of the top plate 3 contacts the facing portion 521. Therefore, when the top plate 3 is viewed from the side (particularly obliquely above), the edge bent portion 529 is not easily noticeable because the line of sight is blocked by the return portion 42. Similarly to the curved portion 42, the edge bent portion 529 also forms a curved surface so that the edge is eliminated, so that the edge bent portion 529 does not stand out more than the curved portion 42. And the edge bending part 529 and the edge bending part 519 and the edge bending part 559 which will be described later are arranged around the edge of the top board 3 on the lower side of the top board 3 so that the top board 3 is trimmed. Visual effects can be obtained. Therefore, the presence of the top plate 3 itself can be emphasized, and the aesthetics can be improved.

このように、フレーム部材52は、保持部52Aが対向部521を備え、下板30の縁端部30Cとの間に天板3の縁部42Aを挟んで保持する構造である。下板30は、トッププレート21への取り付けの際に、縁端部30Cが返し部42の内面側の位置に配置される。ゆえに、フレーム部材52を下板30へ取り付ける場合、取り付け後の向きのままでフレーム部材52を取り付け位置に配置し、止めネジ59を締結してフレーム部材52を下板30に固定する。天板3の縁部42Aは、下板30の縁端部30Cと保持部52Aの対向部521との間に保持されて、位置決めされる。下板30に対し、取り付け後の向きのままで取り付け作業を行うことができるフレーム部材52は、取り付けが容易である。天板3は、フレーム部材52によって、左右方向に沿う辺を構成する部分において縁部42Aの位置決めと保持がなされ、受熱による天板3の反りが防止される。   Thus, the frame member 52 has a structure in which the holding portion 52A includes the facing portion 521 and holds the edge portion 42A of the top plate 3 between the edge portion 30C of the lower plate 30. When the lower plate 30 is attached to the top plate 21, the edge portion 30 </ b> C is disposed at a position on the inner surface side of the return portion 42. Therefore, when the frame member 52 is attached to the lower plate 30, the frame member 52 is arranged at the attachment position in the orientation after the attachment, and the set screw 59 is fastened to fix the frame member 52 to the lower plate 30. The edge portion 42A of the top plate 3 is held and positioned between the edge portion 30C of the lower plate 30 and the facing portion 521 of the holding portion 52A. The frame member 52 that can be attached to the lower plate 30 in the orientation after the attachment is easy to attach. The top plate 3 is positioned and held by the frame member 52 at the portion constituting the side along the left-right direction, and the warp of the top plate 3 due to heat reception is prevented.

次に、図3,図6〜図8に示すフレーム部材55は、フレーム部材51,52と同様に、アルミニウムまたはアルミニウム合金からなり、平面視略扇形状の部材である。フレーム部材52は、天板3の裏面3Bで四つの角部分にそれぞれ取り付けられる。   Next, the frame member 55 shown in FIGS. 3 and 6 to 8 is made of aluminum or an aluminum alloy and is a substantially fan-shaped member in plan view, like the frame members 51 and 52. The frame member 52 is attached to each of the four corners on the back surface 3B of the top plate 3.

図6〜図8に示すように、フレーム部材55は、保持部55A、連結部55B、連結部55C、および貼設部55Dを備える。保持部55Aは、返し部45の角部45Aを保持する部位であり、扇形状のフレーム部材55において円弧部分を構成する辺に設けられる。図6,図7に示すように、保持部55Aは、フレーム部材51の保持部51Aと同様に、厚み方向において所定間隙を離し、互いに向き合って配置される2つの対向部551,552を備える。フレーム部材55がフレーム部材51,52を介して下板30に固定された場合に、対向部551は返し部45の角部45Aに対して下方に配置され、角部45Aにおいて面方向が下方を向く天面3Aと向き合う。同様に対向部552は角部45Aに対して上方に配置され、角部45Aにおいて面方向が上方を向く裏面3Bと向き合う。   As shown in FIGS. 6 to 8, the frame member 55 includes a holding portion 55A, a connecting portion 55B, a connecting portion 55C, and a pasting portion 55D. The holding portion 55 </ b> A is a portion that holds the corner portion 45 </ b> A of the return portion 45, and is provided on a side that forms an arc portion in the fan-shaped frame member 55. As shown in FIGS. 6 and 7, the holding portion 55 </ b> A includes two facing portions 551 and 552 that are arranged to face each other with a predetermined gap in the thickness direction, like the holding portion 51 </ b> A of the frame member 51. When the frame member 55 is fixed to the lower plate 30 via the frame members 51 and 52, the facing portion 551 is disposed below the corner portion 45A of the return portion 45, and the surface direction of the corner portion 45A is downward. It faces the top surface 3A. Similarly, the facing portion 552 is disposed above the corner portion 45A and faces the back surface 3B with the surface direction facing upward at the corner portion 45A.

図6に示すように、下板30は四つの角部分に切り欠きが設けられており、天板3の裏面3Bとの間に生じる段差によって、下板30の切り欠かれた断面と角部45Aの端面を縁とする凹部状をなし、フレーム部材55よりも若干大きな大きさの凹部3Dが形成されている。フレーム部材55は、天板3に取り付ける場合に凹部3D内に配置されるので、フレーム部材55の配置位置の位置決めを行いやすい。また、フレーム部材55は、凹部3D内でスライド移動が可能である。後述するが、フレーム部材55にフレーム部材51,52を連結する場合に、凹部3D内でフレーム部材55をスライド移動させることで、連結位置の位置決めを行いやすい。   As shown in FIG. 6, the lower plate 30 is provided with cutouts at four corners, and a cutaway section and corners of the lower plate 30 are formed by a step generated between the lower plate 30 and the back surface 3B of the top plate 3. A recess 3D having an edge at the end face of 45A is formed, and a recess 3D having a size slightly larger than the frame member 55 is formed. Since the frame member 55 is disposed in the recess 3D when attached to the top plate 3, it is easy to position the arrangement position of the frame member 55. Further, the frame member 55 can be slid in the recess 3D. As will be described later, when the frame members 51 and 52 are coupled to the frame member 55, it is easy to position the coupling position by sliding the frame member 55 within the recess 3D.

図6,図7に示すように、対向部551と対向部552との間の間隙は、上記同様、ホーロー溜まりによって角部45Aの厚みが増しても間に配置できるように、角部45Aにおける天板3の厚みよりも大きく形成されている。そして、天板3が角部分においても自重によって角部45Aを下方に押しつけるので、角部45Aは、下側に配置される対向部551と密接する。ゆえに、側方から保持部55A内をのぞき込んでも角部45Aひいてはホーロー溜まりを視認することはできず、返し部45を備えたことによる天板3の美観は損なわれない。   As shown in FIGS. 6 and 7, the gap between the facing portion 551 and the facing portion 552 is similar to the above in the corner portion 45 </ b> A so that it can be disposed even if the thickness of the corner portion 45 </ b> A increases due to enamel accumulation. It is formed larger than the thickness of the top 3. And since the top plate 3 presses the corner 45A downward by its own weight even at the corner, the corner 45A is in close contact with the facing portion 551 disposed on the lower side. Therefore, even if the inside of the holding portion 55A is looked into from the side, the corner portion 45A and hence the enamel pool cannot be visually recognized, and the aesthetic appearance of the top board 3 provided with the return portion 45 is not impaired.

連結部55Bおよび55Cは、フレーム部材55がそれぞれフレーム部材51および52と連結するための部位である。図6に示すように、連結部55Bは、フレーム部材55が天板3に固定された場合に、扇形状のフレーム部材55において前後方向に沿う辺から左右方向に突出して設けられる。連結部55Bは板状に形成され、フレーム部材51の端部に設けられた連結部51Cとの接触面積が確保される。連結部55Bは、板面に、下方へ向けて突出する突起部553を備える。前述したように、突起部553はフレーム部材51の連結部51Cに設けられた係合穴514に係合し、フレーム部材55とフレーム部材51との連結位置の位置決めを行う。フレーム部材55とフレーム部材51とが連結する場合、フレーム部材55の連結部55Bは、フレーム部材51の連結部51Cよりも天板3のトッププレート21に近い位置に配置される。言い換えると、フレーム部材55の連結部55Bは、天板3とフレーム部材51の連結部51Cとの間に挟まれる。フレーム部材55はフレーム部材51と連結部55Bにおいて密着して熱伝導できるようになる。   The connecting portions 55B and 55C are parts for connecting the frame member 55 to the frame members 51 and 52, respectively. As shown in FIG. 6, when the frame member 55 is fixed to the top plate 3, the connecting portion 55 </ b> B is provided to protrude in the left-right direction from the side along the front-rear direction in the fan-shaped frame member 55. The connecting portion 55B is formed in a plate shape, and a contact area with the connecting portion 51C provided at the end of the frame member 51 is ensured. The connecting portion 55B includes a protruding portion 553 that protrudes downward on the plate surface. As described above, the protrusion 553 engages with the engagement hole 514 provided in the connection portion 51 </ b> C of the frame member 51, and positions the connection position between the frame member 55 and the frame member 51. When the frame member 55 and the frame member 51 are connected, the connecting portion 55B of the frame member 55 is disposed at a position closer to the top plate 21 of the top plate 3 than the connecting portion 51C of the frame member 51. In other words, the connecting portion 55B of the frame member 55 is sandwiched between the top plate 3 and the connecting portion 51C of the frame member 51. The frame member 55 is in close contact with the frame member 51 at the connecting portion 55B and can conduct heat.

図6,図8に示すように、連結部55Cは、フレーム部材55が天板3に固定された場合に、扇形状のフレーム部材55において左右方向に沿う辺から前後方向に突出して設けられる。連結部55Cも、フレーム部材52端部の連結部52Cとの接触面積を確保するため、連結部52Cの形状に合わせた段部を有する板状に形成される。連結部55Cは、厚みの薄い側の段部には、板面に、フレーム部材52の連結部52Cに設けられた係合穴524に係合するため、下方へ向けて突出する突起部554を備える。厚みの厚い側の段部には、連結部52Cの挿通穴525を挿通して締結される止めネジ556が締結するネジ穴555が形成されている。フレーム部材55とフレーム部材52とが連結する場合、連結部55Cは、天板3と連結部52Cとの間に挟まれる。フレーム部材55は、上記同様に、突起部554によってフレーム部材52との連結位置の位置決めがなされ、連結部52Cと55Cとが密着して熱伝導できるようになる。さらに、止めネジ556の締結によって、フレーム部材55がフレーム部材52に固定されることによって、フレーム部材55が天板3から脱落するのが防止される。   As shown in FIGS. 6 and 8, when the frame member 55 is fixed to the top plate 3, the connecting portion 55 </ b> C is provided to protrude in the front-rear direction from the side along the left-right direction in the fan-shaped frame member 55. The connecting portion 55C is also formed in a plate shape having a step portion that matches the shape of the connecting portion 52C in order to ensure a contact area with the connecting portion 52C at the end of the frame member 52. Since the connecting portion 55C is engaged with the engaging hole 524 provided in the connecting portion 52C of the frame member 52 on the plate surface at the thin step portion, the protruding portion 554 that protrudes downward is provided. Prepare. A screw hole 555 for fastening a set screw 556 inserted through the insertion hole 525 of the connecting portion 52C and fastened is formed in the step portion on the thicker side. When the frame member 55 and the frame member 52 are connected, the connecting portion 55C is sandwiched between the top plate 3 and the connecting portion 52C. Similarly to the above, the frame member 55 is positioned at the connection position with the frame member 52 by the projection 554, and the connection portions 52C and 55C are in close contact with each other so as to conduct heat. Further, the frame member 55 is fixed to the frame member 52 by fastening of the set screw 556, thereby preventing the frame member 55 from falling off the top plate 3.

貼設部55Dは、保持部55Aにおける対向部551の下側の面と、対向部551の縁を下方へ折り返した縁曲げ部559の内側の面によって構成される部位であり、上記同様、パッキン29が位置決めされて貼り付けられる。フレーム部材55とフレーム部材51とフレーム部材52とが連結することにより、それぞれの貼設部55D,51D,52Dが天板3の縁を一周して接続し、それにあわせてパッキン29も、天板3の縁を一周して設けられる。なお、対向部551も、上側の面が、縁曲げ部559における外側の面へ向けて連続して滑らかな曲面を構成するように形成されており、エッジがない。上記同様、縁曲げ部559は、保持部55Aが天板3の角部45Aを保持した場合に、返し部45よりも天板3の内方側に位置するように、対向部551に設けられている。そして、天板3の角部45Aが対向部551と当接する位置において、返し部45における天面3Aが構成する曲面と、縁曲げ部559における曲面とが合流する。ゆえに、天板3を側方(特に斜め上方)からみた場合に、縁曲げ部559は返し部45によって視線が遮られ、目立ちにくい。また、曲面構成する返し部45と同様に縁曲げ部559も曲面を構成してエッジをなくすことによって、縁曲げ部559が返し部45よりも目立つことがない。そして、縁曲げ部559が縁曲げ部519,529とともに天板3の下側で天板3の縁に沿って一周して配置されることで、天板3が縁取りされる視覚効果を得ることができる。よって、天板3自体の存在感を際立たせることができ、美観向上を図ることができる。   The affixing portion 55D is a portion constituted by a lower surface of the facing portion 551 in the holding portion 55A and an inner surface of an edge bent portion 559 where the edge of the facing portion 551 is folded downward. 29 is positioned and affixed. When the frame member 55, the frame member 51, and the frame member 52 are connected, the respective attaching portions 55D, 51D, and 52D are connected around the edge of the top plate 3, and the packing 29 is also connected to the top plate 3 accordingly. 3 is provided around the edge of 3. Note that the facing portion 551 is also formed so that the upper surface continuously forms a smooth curved surface toward the outer surface of the edge bent portion 559 and has no edge. Similarly to the above, the edge bent portion 559 is provided in the facing portion 551 so as to be positioned on the inner side of the top plate 3 with respect to the return portion 45 when the holding portion 55A holds the corner portion 45A of the top plate 3. ing. Then, the curved surface formed by the top surface 3 </ b> A of the return portion 45 and the curved surface of the edge bent portion 559 merge at a position where the corner portion 45 </ b> A of the top plate 3 contacts the facing portion 551. Therefore, when the top plate 3 is viewed from the side (especially obliquely upward), the edge bending portion 559 is blocked by the return portion 45 and the line of sight is hardly noticeable. Further, similarly to the curved portion 45, the edge bent portion 559 also forms a curved surface and eliminates the edge, so that the edge bent portion 559 does not stand out more than the curved portion 45. And the edge bending part 559 and the edge bending parts 519 and 529 are arranged around the edge of the top plate 3 below the top plate 3 to obtain a visual effect that the top plate 3 is trimmed. Can do. Therefore, the presence of the top plate 3 itself can be emphasized, and the aesthetics can be improved.

このように、フレーム部材55は、保持部55Aが対向部551と552との間に天板3の角部45Aを挟んで保持する構造である。ゆえに、フレーム部材51を天板3に取り付ける場合、保持部55A側に対してネジ穴555が形成された側を天板3の裏面3Bから遠ざけた状態にフレーム部材55を傾け、天板3の角部45Aを対向部551,552間に配置する。その状態で保持部55Aを支点にフレーム部材55を回転させて、ネジ穴555側を裏面3Bに近づける。フレーム部材55は下板30への固定構造は持たず、連結部55B,55Cを介して連結するフレーム部材51,52を下板30に固定することでフレーム部材51,52に支えられ、間接的に下板30に固定される。天板3は、フレーム部材55によって、角部分においても角部45Aの位置決めと保持がなされ、受熱による天板3の反りが防止される。   Thus, the frame member 55 has a structure in which the holding portion 55A holds the corner portion 45A of the top plate 3 between the facing portions 551 and 552. Therefore, when attaching the frame member 51 to the top plate 3, the frame member 55 is inclined so that the side on which the screw hole 555 is formed with respect to the holding portion 55 </ b> A side is away from the back surface 3 </ b> B of the top plate 3. The corner portion 45 </ b> A is disposed between the facing portions 551 and 552. In this state, the frame member 55 is rotated with the holding portion 55A as a fulcrum, and the screw hole 555 side is brought close to the back surface 3B. The frame member 55 does not have a structure for fixing to the lower plate 30, and is supported by the frame members 51 and 52 by fixing the frame members 51 and 52 connected via the connecting portions 55 </ b> B and 55 </ b> C to the lower plate 30. To the lower plate 30. The top plate 3 is positioned and held at the corner portion 45 by the frame member 55, and the warp of the top plate 3 due to heat reception is prevented.

以上説明したように、天板3は、ホーロー処理によって表面処理を行うため、縁部41A,42Aにホーロー溜まりが形成され、凹凸を生じる場合がある。第一保持部材の一例である下板30とフレーム部材51は、フレーム部材51の保持部51Aに設けた対向部511,512で天板3の縁部41Aを挟むことができる。また、第一保持部材の一例である下板30とフレーム部材52は、フレーム部材52の保持部52Aに設けた対向部521と、下板30の前後方向における縁端部30Cとで天板3の縁部42Aを挟むことができる。ゆえに、コンロ1の製造過程において、天板3の縁部41A,42Aにホーロー溜まりがあっても、対向部511,512間または対向部521と縁端部30Cとの間に縁部41Aまたは42Aを配置し、コンロ1を組み立てることは容易である。そして、対向部511,512間または対向部521と縁端部30Cとの間に縁部41Aまたは42Aを挟むので、天板3の縁部41A,42Aを位置決めし、天板3の受熱による反りを確実に抑制することができる。また、天板3の縁部41A,42Aは、返し部41,42によって、天板3の内向きに返された位置にある。ゆえに、縁部41A,42Aにホーロー溜まりによる凹凸があっても、コンロ1の側方から見えにくく、美観は損なわれない。さらに、縁部41A,42Aを対向部511,512間または対向部521と縁端部30Cとの間に挟む構成によってホーロー溜まりを隠すことができ、コンロ1の美観は損なわれない。   As described above, since the top plate 3 is subjected to surface treatment by enamel treatment, enamel pools may be formed at the edges 41A and 42A, resulting in unevenness. The lower plate 30 and the frame member 51, which are examples of the first holding member, can sandwich the edge portion 41 </ b> A of the top plate 3 between the opposed portions 511 and 512 provided on the holding portion 51 </ b> A of the frame member 51. Further, the lower plate 30 and the frame member 52, which are examples of the first holding member, include a counter plate 521 provided on the holding portion 52 </ b> A of the frame member 52 and an edge portion 30 </ b> C in the front-rear direction of the lower plate 30. The edge portion 42A can be sandwiched. Therefore, in the manufacturing process of the stove 1, even if there are enamel pools at the edges 41A and 42A of the top plate 3, the edges 41A or 42A between the facing parts 511 and 512 or between the facing part 521 and the edge part 30C. Assembling the stove 1 is easy. Since the edge 41A or 42A is sandwiched between the facing parts 511 and 512 or between the facing part 521 and the edge part 30C, the edges 41A and 42A of the top board 3 are positioned, and the warp due to heat reception of the top board 3 Can be reliably suppressed. Further, the edge portions 41 </ b> A and 42 </ b> A of the top plate 3 are located at positions where the return portions 41 and 42 are returned inward of the top plate 3. Therefore, even if the edges 41A and 42A have irregularities due to enamel accumulation, it is difficult to see from the side of the stove 1 and the aesthetic appearance is not impaired. Furthermore, the enamel pool can be hidden by the configuration in which the edge portions 41A and 42A are sandwiched between the facing portions 511 and 512 or between the facing portion 521 and the edge end portion 30C, and the aesthetic appearance of the stove 1 is not impaired.

また、対向部521を有するフレーム部材52は、下板30の縁端部30Cとの間で天板3の縁部42Aを挟むことができる。すなわち、縁端部30Cが下板30の部位として下板30と一体であるので、組み付け時において、縁部42Aに対してフレーム部材52を取り付け後と同じ向きで下方側から被せるようにして配置することができる。その状態で、フレーム部材52を下板30に固定すれば、下板30の縁端部30Cとフレーム部材52の対向部521との間に縁部42Aを挟み、縁部42Aの位置決めを確実に行うことができる。ゆえに、フレーム部材52は、組み付け後の向きが組み付け前の向きと同じ向きのまま下板に固定することができるので、組み付け作業が容易である。   Further, the frame member 52 having the facing portion 521 can sandwich the edge portion 42 </ b> A of the top plate 3 with the edge portion 30 </ b> C of the lower plate 30. That is, since the edge portion 30C is integral with the lower plate 30 as a portion of the lower plate 30, the frame member 52 is disposed so as to cover the edge portion 42A from the lower side in the same direction as after the attachment. can do. If the frame member 52 is fixed to the lower plate 30 in this state, the edge portion 42A is sandwiched between the edge portion 30C of the lower plate 30 and the facing portion 521 of the frame member 52, and the positioning of the edge portion 42A is ensured. It can be carried out. Therefore, the frame member 52 can be fixed to the lower plate while the orientation after the assembly is the same as the orientation before the assembly, so that the assembly operation is easy.

さらに、フレーム部材55の対向部551,552間に天板3の角部45Aを挟んで位置決めすることで、天板3の角部45Aにおいても反りを抑制することができる。また、フレーム部材55は、フレーム部材51,52で天板3の裏面3Bとの間に挟んで位置決めできるので、下板30にフレーム部材55を固定するための部位や部材を用意せずとも済み、部品点数や取り付けの手間を低減できる。そして、隣り合う二辺に配置した2つのフレーム部材51,52をフレーム部材55で連結することができるので、フレーム部材51,52およびフレーム部材55の強度を高め、天板3の縁部41A,42Aおよび角部45Aをそれぞれ挟み、位置決めした状態を維持することができる。   Further, by positioning the corner portion 45A of the top plate 3 between the facing portions 551 and 552 of the frame member 55, it is possible to suppress warpage in the corner portion 45A of the top plate 3 as well. Further, since the frame member 55 can be positioned by being sandwiched between the frame members 51 and 52 and the back surface 3B of the top plate 3, it is not necessary to prepare a part or member for fixing the frame member 55 to the lower plate 30. , The number of parts and labor of installation can be reduced. And since the two frame members 51 and 52 arrange | positioned at two adjacent sides can be connected by the frame member 55, the intensity | strength of the frame members 51 and 52 and the frame member 55 is raised, and the edge part 41A of the top plate 3, 42A and corner portion 45A can be sandwiched and maintained in a positioned state.

また、対向部511と対向部512を有するフレーム部材51は、下板30の縁端部30Bが設けられた辺側において、対向部511と対向部512と間に縁部41Aを挟むことができる。組み付け時において、フレーム部材51を天板3の縁部41Aに向けて斜めに傾け、差し込めば、対向部511と対向部512の間に縁部41Aを配置することができる。その状態でフレーム部材51の傾きを戻して下板30に固定すれば、縁部41Aが対向部511と対向部512に挟まれた状態で抜けにくくなるので、フレーム部材51の組み付け作業も容易に行うことができる。また、対向部511と対向部512とが一体であり間隙が広がることがないので、天板3の縁部41Aをより確実に位置決めすることができる。   Further, the frame member 51 having the facing portion 511 and the facing portion 512 can sandwich the edge portion 41A between the facing portion 511 and the facing portion 512 on the side where the edge portion 30B of the lower plate 30 is provided. . At the time of assembly, if the frame member 51 is tilted obliquely toward the edge 41A of the top plate 3 and inserted, the edge 41A can be disposed between the facing portion 511 and the facing portion 512. If the inclination of the frame member 51 is returned and fixed to the lower plate 30 in this state, the edge portion 41A is difficult to come out while being sandwiched between the facing portion 511 and the facing portion 512, so that the assembly work of the frame member 51 is easy. It can be carried out. Moreover, since the opposing part 511 and the opposing part 512 are integral and a space | gap does not spread, the edge part 41A of the top plate 3 can be positioned more reliably.

そして、天板3の辺に応じ、フレーム部材51を利用したり、フレーム部材52を利用したりすることができるので、天板3に対するフレーム部材51,52の組み付け作業が容易であり、且つ、縁部41A,42Aの位置決めを確実に行うことができる。   And since the frame member 51 or the frame member 52 can be used according to the sides of the top plate 3, the assembly work of the frame members 51 and 52 to the top plate 3 is easy, and The positioning of the edges 41A and 42A can be performed reliably.

また、天板3の縁に沿って天板3を一周してフレーム部材51,52,55を配置することで、天板3の全周に亘って天板3の縁部41A,42Aおよび角部45Aを確実に挟み、位置決めすることができる。また、フレーム部材51,52,55の対向部511,521,551は、天板3の縁部41A,42Aおよび角部45Aにおける天面3A側で縁部41A,42Aおよび角部45Aそれぞれを挟む構成であるため、天板3の縁に沿って天板3の側方から視認できる位置に配置される。すなわち、天板3を斜め方向からみた場合に、対向部511,521,551は天板3の下側で縁に沿って一周して配置される構成となるため、天板3が縁取りされる視覚効果を得ることができる。よって、天板3自体の存在感を際立たせることができ、美観向上を図ることができる。また、天板3が局所的に高温になった場合、互いに連結するフレーム部材51,52,55は天板3の熱を伝導して放熱することができるので、天板3の局所的な高温化を防ぎ、受熱による天板3の反りを、より確実に防止できる。なお、フレーム部材51,52,55にアルミニウムまたはアルミニウム合金を用いれば、放熱効果をより高めることができ、好ましい。   Further, by arranging the frame members 51, 52, 55 around the top plate 3 along the edge of the top plate 3, the edges 41 </ b> A, 42 </ b> A and corners of the top plate 3 are arranged over the entire periphery of the top plate 3. The portion 45A can be reliably pinched and positioned. Further, the facing portions 511, 521, 551 of the frame members 51, 52, 55 sandwich the edge portions 41A, 42A and the corner portions 45A on the top surface 3A side of the edge portions 41A, 42A and the corner portions 45A of the top plate 3, respectively. Since it is a structure, it arrange | positions in the position which can be visually recognized from the side of the top plate 3 along the edge of the top plate 3. That is, when the top plate 3 is viewed from an oblique direction, the facing portions 511, 521, and 551 are configured to be arranged around the edge on the lower side of the top plate 3, so that the top plate 3 is trimmed. A visual effect can be obtained. Therefore, the presence of the top plate 3 itself can be emphasized, and the aesthetics can be improved. Further, when the top plate 3 is locally heated, the frame members 51, 52, and 55 that are connected to each other can conduct and dissipate the heat of the top plate 3, so that the locally high temperature of the top plate 3 is increased. The warping of the top plate 3 due to heat reception can be prevented more reliably. Note that it is preferable to use aluminum or an aluminum alloy for the frame members 51, 52, and 55 because the heat dissipation effect can be further enhanced.

天板3は、通常、左右方向に長く延びるため、受熱した場合に、前後方向と比べると左右方向において反りを生じやすい。そこで、対向部511と対向部512とを一体に有し、間隙が広がることのないフレーム部材51を、天板3の左方側および右方側の辺に設けた縁部41Aの位置決めに用いることで、天板3の受熱による反りを確実に防止できる。そして、前方側および後方側に設けた縁部42Aの位置決めには、下板に固定しやすいフレーム部材52を用いれば、コンロ1の組み立てが容易である。   Since the top plate 3 normally extends in the left-right direction, the top plate 3 tends to warp in the left-right direction compared to the front-rear direction when receiving heat. Therefore, the frame member 51 that has the opposing portion 511 and the opposing portion 512 integrally and does not widen the gap is used for positioning the edge portion 41A provided on the left side and the right side of the top plate 3. Thus, warping due to heat reception of the top plate 3 can be reliably prevented. For positioning of the edge portion 42A provided on the front side and the rear side, if the frame member 52 that is easily fixed to the lower plate is used, the stove 1 can be easily assembled.

なお、本発明は上記実施形態に限定されるものではなく、種々の変更が可能である。例えば、コンロ1はビルトインコンロであるが、テーブルコンロであってもよい。またコンロ1は複数のバーナ4〜6を備えるが、バーナは1つでもよく、グリルは無くてもよい。   In addition, this invention is not limited to the said embodiment, A various change is possible. For example, the stove 1 is a built-in stove, but may be a table stove. The stove 1 includes a plurality of burners 4 to 6, but the number of burners may be one and the grill may not be provided.

天板3は、トッププレート21の両面(天面3Aおよび裏面3B)にホーロー処理を施したが、天面3Aにのみホーロー処理を施してもよい。また、天板3の四方の辺および四つの角(すなわち全周)に返し部41,42,45を設けたが、左右の辺のみ、あるいは前側の辺のみに返し部を設けるなどしてもよく、必ずしも全周に設けなくともよい。同様に、下板30およびフレーム部材51,52による縁部41A,42Aの保持は、必ずしも全周においてなされなくともよい。フレーム部材55も、天板3の四つの角すべてに設けなくともよい。また、天板3の一つの辺の全長に亘って縁部41Aまたは42Aの保持が行われなくともよい。言い換えると、フレーム部材51,52は、天板3の一つの辺において部分的に(間欠的に)設けてもよいし、部分的に設ける場合にはさらに、一つの辺に複数設けてもよい。また、本実施形態ではトッププレート21と後板22を組み合わせた天板3について説明を行ったが、後板の機能をトッププレートが有し、天板は、トッププレートのみからなるものであってもよい。   Although the top plate 3 has been subjected to enamel processing on both surfaces (the top surface 3A and the back surface 3B) of the top plate 21, it may be subjected only to the top surface 3A. Further, although the return portions 41, 42, 45 are provided on the four sides and four corners (that is, the entire circumference) of the top plate 3, it is also possible to provide the return portions only on the left and right sides or only on the front side. It is not always necessary to provide the entire circumference. Similarly, the holding of the edges 41A and 42A by the lower plate 30 and the frame members 51 and 52 may not necessarily be performed on the entire circumference. The frame member 55 may not be provided at all four corners of the top plate 3. Further, the edge 41A or 42A may not be held over the entire length of one side of the top plate 3. In other words, the frame members 51 and 52 may be provided partially (intermittently) on one side of the top plate 3, or when provided partially, a plurality of frame members 51 and 52 may be provided on one side. . Moreover, although the top plate 3 which combined the top plate 21 and the back plate 22 was demonstrated in this embodiment, the top plate has the function of the back plate, and the top plate is composed only of the top plate. Also good.

また、天板3の左右の縁部41Aは下板30とフレーム部材51で保持し、前後の縁部42Aは下板30とフレーム部材52で保持したが、すべての辺を、下板30とフレーム部材51のみ、あるいは下板30とフレーム部材52のみで保持してもよい。天板3のすべての辺を下板30とフレーム部材52のみで保持する場合、縁端部30Cが下板30の部位として下板と一体であるので、組み付け時において、縁部42Aに対してフレーム部材52を下方側から被せるようにして配置することができる。その状態で、フレーム部材52を下板30に固定すれば、下板30の縁端部30Cとフレーム部材52の対向部521との間に縁部42Aを挟み、縁部42Aの位置決めを確実に行うことができる。ゆえに、フレーム部材52は、組み付け後の向きが組み付け前の向きと同じ向きのまま下板に固定することができるので、組み付け作業が容易である。一方、天板3のすべての辺を、下板30とフレーム部材51のみで保持する場合、組み付け時において、フレーム部材51を天板3の縁部41Aに向けて斜めに傾け、差し込めば、対向部511と対向部512の間隙に縁部41Aを配置することができる。その状態でフレーム部材51の傾きを戻して下板30に固定すれば、縁部41Aが対向部511と対向部512に挟まれた状態で抜けにくくなるので、フレーム部材51の組み付け作業も容易に行うことができる。また、対向部511と対向部512の間隙が広がることがないので、天板3の縁部41Aをより確実に位置決めすることができる。   Further, the left and right edge portions 41A of the top plate 3 are held by the lower plate 30 and the frame member 51, and the front and rear edge portions 42A are held by the lower plate 30 and the frame member 52. You may hold | maintain only with the frame member 51, or only the lower board 30 and the frame member 52. FIG. When all the sides of the top plate 3 are held only by the lower plate 30 and the frame member 52, the edge portion 30C is integral with the lower plate as a portion of the lower plate 30, and therefore, when assembled, the edge portion 42C is not attached to the edge portion 42A. The frame member 52 can be disposed so as to be covered from below. If the frame member 52 is fixed to the lower plate 30 in this state, the edge portion 42A is sandwiched between the edge portion 30C of the lower plate 30 and the facing portion 521 of the frame member 52, and the positioning of the edge portion 42A is ensured. It can be carried out. Therefore, the frame member 52 can be fixed to the lower plate while the orientation after the assembly is the same as the orientation before the assembly, so that the assembly operation is easy. On the other hand, when all the sides of the top plate 3 are held only by the lower plate 30 and the frame member 51, when assembling, the frame member 51 is inclined obliquely toward the edge 41A of the top plate 3 and inserted to face each other. The edge portion 41 </ b> A can be disposed in the gap between the portion 511 and the facing portion 512. If the inclination of the frame member 51 is returned and fixed to the lower plate 30 in this state, the edge portion 41A is difficult to come out while being sandwiched between the facing portion 511 and the facing portion 512, so that the assembly work of the frame member 51 is easy. It can be carried out. In addition, since the gap between the facing portion 511 and the facing portion 512 does not widen, the edge portion 41A of the top plate 3 can be positioned more reliably.
