【発明の属する技術分野】
本発明は、コンロに使用される五徳に関する。
【０００２】
【従来の技術】
ガスコンロ等のコンロでは、コンロ本体の上面の開口を覆う天板に煮こぼれ汁等が付着するのを防止するために、天板の上面にホーローやフッ素コーティング等の保護層を設けることがよく行われる。またこの天板上には鉄製の五徳が載置されるが、五徳により擦られると天板の上面に傷が付く。特に上面に保護層を設けた天板では傷が付きやすい。
【０００３】
そこで、五徳の底面に凹部を設けて、該凹部に耐熱性の緩衝体（パッキン）を差し込むことにより取り付けて、五徳の擦れによる天板の傷付き防止を図ったものが知られている（例えば、特許文献１参照）。
【０００４】
【特許文献１】
特開平１０−３００１０４号公報（図１のブッシュ４５）
【０００５】
【発明が解決しようとする課題】
しかしながら、五徳の底面の凹部に緩衝体を差し込んだだけでは、緩衝体が強く擦られたときに外れやすく、緩衝体の外れにより天板の傷付き防止を図ることができず、また五徳のガタ付きを招く。また鉄製の五徳は熱が伝わりやすく、緩衝体が伝熱により劣化したり溶けたりする恐れがあり、緩衝体の耐久性にも欠け、またそれが外れる原因ともなる。
【０００６】
したがって、本発明の課題は、底面に耐熱性の緩衝体を具備した五徳において、緩衝体の外れをなくすと共に、緩衝体の熱による劣化を防止して耐久性を高めることである。
【０００７】
【課題を解決するための手段】
上記課題を解決するために、本発明は、コンロに使用される五徳であって、耐熱性の緩衝体が五徳の底面に形成された凹部に、該底面からその下部分が突出して取り付けられる五徳において、前記緩衝体は前記凹部の天面に断熱材を介在させて、該緩衝体の底面に設けた凹陥部に頭部が没するねじにより取り付けられることを特徴とする。
【０００８】
なお、五徳は複数本の爪片とこれらを連結する枠体からなり、凹部が形成される五徳の底面は、爪片の底面か枠体の底面のどちらでもよい。
【０００９】
本発明では、五徳の底面に設けた凹部に耐熱性緩衝体をねじ止めしたので、緩衝体が強く擦られても外れることがなく、安定して緩衝体による天板の傷付き防止を図ることができ、また緩衝体の外れによる五徳のガタ付きを招くこともなくなる。また五徳の底面の凹部に緩衝体を断熱材を介して取り付けたので、五徳の熱が緩衝体へ伝達するのを低減でき、緩衝体の熱による劣化を防いで高耐久性なものにできる。
【００１０】
本発明によれば、前記緩衝体は前記凹部に、該凹部の内側側壁と間隔を存し又は点接触して取り付けることができる。これにより、緩衝体への伝熱をより低減して、緩衝体の熱による劣化防止を向上することができる。又緩衝体は内側側壁との接触が点接触であれば凹部の中で位置決めされる。特にねじ止めの際等に緩衝体が回動することなく位置決めされることとなる。
【００１１】
また前記緩衝体の上面に前記断熱材の下部を収容する収容部を形成し、該収容部に収容される断熱材の下部は収容部の内側側壁に当たり回動しない形状とすることができる。このようにすれば、凹部に取り付けた断熱材が外から見えづらくなって、見栄えが損なわれなくなり、また緩衝体の取り付け時に、断熱材が緩衝体から位置ずれするのを防止することができる。
【００１２】
また前記凹部の天面に前記断熱材の上部を収容する天面収容部を形成し、該天面収容部に収容される断熱材の上部は天面収容部の内側側壁に当たり回動しない形状とすることができる。このようにすることによっても、凹部に取り付けた断熱材が外から見えづらくなって、見栄えが損なわれなくなり、また緩衝体の取り付け時に、断熱材が凹部中で位置ずれするのを防止することができる。
【００１３】
また前記緩衝体の底面の凹陥部を形成する側壁の下面に複数個の突起を設けることができる。これにより、五徳を天板に対し滑りづらくできる他、天板からの熱の緩衝体への伝達を低減することができ、緩衝体の熱による劣化防止効果をさらに向上することができる。
【００１４】
本発明の一態様では、前記五徳は複数本の放射方向に長手の爪片と該爪片を連結する枠体とからなり、この爪片の底面に形成される凹部は爪片の長手方向の両側面が開口する切り欠き溝であり、該切り欠き溝の開口上縁に水切り部を設けた。水切り部を設けておけば、爪片に垂れた煮汁の量が多くても、煮汁は水切り部を伝わって下に落下するので、爪片の外側面から凹部内に回り込むことがなくなり、断熱材が煮汁により濡れることがない。
【００１５】
【発明の実施の形態】
以下、本発明の実施の形態を詳述する。
【００１６】
図１は本発明の五徳を使用したガスコンロを示す斜視図、図２は同コンロの断面図、図３は五徳の底面図である。
【００１７】
コンロ１０は、ドロップイン式のガラストップコンロで、薄型の矩形状の箱体からなるコンロ本体１２の上面は、天板１３により覆われている。このコンロ本体１２は、システムキッチンのワークトップ２に設けられた開口３の周縁に本体１２の上端のフランジ１２ａを係止させることにより、ワークトップ２の開口３に吊持して設置される。
【００１８】
天板１３は、耐熱性ガラス板（セラミックガラス）１３ａおよびその周囲のトップ枠１３ｂからなり、天板１３の前後方向略中央位置に設けた左右の開口１４には、コンロ本体１２内に収容した内炎式のガスバーナ１１が臨んでいる。天板１３の前寄りの中央部位置には、左右のガスバーナ１１の点火等の操作を行う点火つまみ１５がそれぞれ設けられている。また天板１３の開口１４の周縁部１３ｃには保護リング１６が取り付けられ、天板１３の開口１４の周囲には五徳２０が載置されている。
【００１９】
該バーナ１１の中央開口１７の下方には、コンロ本体１２内の支持板１２ｂに取り付けた環状の係止フレーム１２ｃ上に汁受皿１８が載置されている。バーナ１１の上方には、炎孔１１ａからの炎が天板１３の下方から上方に流れる際に炎を中心方向に導く内側に向かって上方に傾斜する集合部１９ａと、該集合部１９ａによって中心方向に導かれた炎を外上方に導く拡散部１９ｂを備えたガイド部材１９が配設されている。拡散部１９ｂの先端は天板１３の上面と略同一面上に位置しており、拡散部１９ｂと天板１３の開口周縁部１３ｃの保護リング１６との間には数ｍｍの間隙Ｇが設けられている。なお、ガイド部材１９の基部１９ｃはバーナ１１に取り付けられた支持体１２ｄにバーナ１１と間隙Ｔを存して取り付けられており、バーナ１１とガイド部材１９との間に空気が流れて炎をさらに中心方向に導いている。
【００２０】
五徳２０は、放射方向に長手の６本の爪片２１とこれらを連結する環状の五徳枠２２とからなり、各爪片２１の五徳枠２２から径方向外方に突出した脚部２１Ａの位置の底面に形成された凹部に耐熱性緩衝体２４が取り付けられている。五徳２０は爪片２１の底面凹部に取り付けられた緩衝体２４を天板１３に着地して天板１３上に載置される。
【００２１】
五徳枠２２の底面には下に突出する突条環部２２ａが形成され、また突条環部２２ａの基部には全周内方に突出する庇部２２ｂが設けられている。五徳２０が天板１３のガラス板１３ａの上面に着座するときに、突条環部２２ａが前記隙間Ｇに入り込むようにする。これにより五徳２０は位置決めされ、その五徳枠２２は、庇部２２ｂがガイド部材１９の拡散部１９ｂの先端よりも内側に位置し、五徳枠２２の外周縁が保護リング１６の外に位置することによって、前記間隙Ｇを覆い調理時に生じた煮汁が五徳枠２２に落下しても隙間Ｇに落下することはない。
【００２２】
本実施の形態によれば、図２、図４および図５に示すように、五徳２０の爪片２１の脚部２１Ａの底面を爪片２１の外端２１Ｇと内端２１Ｎとを放射方向に結ぶ長手方向に対し直角方向に切り欠いて、凹部２１Ｂを爪片２１の長手方向左右外側面２１Ｃに開口する切り欠き溝に形成すると共に、該凹部２１Ｂの天面２１Ｂ１にねじ取付穴２１Ｂ２を形成した。そして該凹部２１Ｂ内に断熱材としての断熱性シート２５を介して前記の耐熱性緩衝体２４を配設し、緩衝体２４の下面の凹陥部２４Ｂに頭部２６ａが没するねじ２６により、緩衝体２４および断熱性シート２５を凹部２１Ｂの天面２１Ｂ１の取付穴２１Ｂ２で固定した。
【００２３】
このとき緩衝体２４の上面２４Ｕは断熱性シート２５により凹部２１の天面２１Ｂ１に接することはない。また緩衝体２４の下部２４Ｋは爪片２１の脚部２１Ａの底面より高さＨ突出するので、五徳２０が天板１３に載置されたときでも五徳２０の接触するのは緩衝体２４であり天板１３に傷が付かない。
【００２４】
更にこの緩衝体２４は、爪片２１の凹部２１Ｂの内側側壁２１Ｂ３との接触による熱の伝達をなくすために、該内側側壁２１Ｂ３に接触しない小さめの矩形状に形成し、内側側壁２１Ｂ３と間隙を存して取り付けた。
【００２５】
なお、緩衝体２４は内側側壁２１Ｂ３との接触が点接触であれば五徳からの伝熱は殆どないので、緩衝体２４が内側側壁２１Ｂ３と点接触、例えば図５（ｂ）に破線で示すように内側側壁２１Ｂ３を円弧状とすると共に、矩形状の緩衝体２４の角部のみが内側側壁２１Ｂ３と点接触する構造や、図５（ｃ）に示すように、内側側壁２１Ｂ３から内方に突出する突起２８を形成して点接触する構造や、図５（ｄ）に示すように、緩衝体２４の側面から外方に突出する突起２９を形成して緩衝体２４と内側側壁２１Ｂ３が点接触するようにしてもよい。このようにすることにより緩衝体２４が凹部２１Ｂの中で位置決めされる。特にねじ止めの際等に緩衝体２４が回動することなく位置決めされることとなる。
【００２６】
耐熱性緩衝体２４としては例えばシリコンゴム（耐熱温度３００℃）を用い、断熱性シート２５としてはセラミックウールの不織布を用いた。
【００２７】
また好ましくは、緩衝体２４の上面には矩形状の収容部２４Ａを形成して、収容部２４Ａに断熱性シート２５の下半部を収容して支持させる。このようにすれば、凹部２１Ｂに取り付けた断熱性シート２５が外から見えづらくなって、見栄えが損なわれなくなり、また緩衝体２４の取り付け時に、断熱性シート２５が緩衝体２４から位置ずれするのを防止することができる。
【００２８】
またこの実施の形態では、緩衝体２４の上面の収容部２４Ａは、該収容部２４Ａを形成する側壁２４Ａ１を凹部２１Ｂの両側の開口に位置する側、即ち脚部２１Ａの両側面２１Ｃの側は残して、凹部２１Ｂの１対の内側側壁２１Ｂ３と対向する側は切り欠いて切り欠き部２４Ａ２とした形状とした。
【００２９】
なお、断熱性シート２５の緩衝体２４への位置決めは、断熱性シート２５のための収容部２４Ａを構成する側壁２４Ａ１に対し、断熱性シート２５の側面２５Ａ１が隣接することによって位置決めされて、断熱性シート２５が収容部２４Ａの内部で回動しないようになっている。
【００３０】
なお、凹部２１Ｂの天面２１Ｂ１に図５（ａ）に点線で示すように、断熱性シート２５を収容する天面収容部２１Ｂ２を形成し、該天面収容部２１Ｂ２に収容される断熱性シート２５の上部は、天面収容部の内側側壁に当たり回動しない形状とすることができる。
【００３１】
このようにすることによっても、凹部２１Ｂに取り付けた断熱性シート２５が外から見えづらくなって、見栄えが損なわれなくなり、また緩衝体２４の取り付け時に、断熱性シート２５が凹部２１Ｂ中で位置ずれするのを防止することができる。
【００３２】
また緩衝体２４の下面の凹陥部２４Ｂは、凹陥部２４Ｂを形成する側壁２４Ｂ１を収容部２４Ａの切り欠き部２４Ａ２と同側は残して、切り欠き部２４Ａ２と直角に対向する側は切り欠いて切り欠き部２４Ｂ２に形成すれば、緩衝体２４の形状のバランスが取れて、ねじ２６を締めた際の緩衝体２４の変形を防止することができる。２４Ｃはねじ２６用の孔である。
【００３３】
なお、収容部２４Ａは対向する２辺の側壁２４Ａ１の間の溝状収容部としたが、側壁２４Ａ１で４辺が囲まれた凹部とすることもできる。また凹陥部２４Ｂも切り欠き部２４Ｂ２による溝状凹陥部としたが、側壁２４Ｂ１で４辺が囲まれた凹陥部とすることもできる。
【００３４】
本実施の形態の五徳は、以上のように構成され、五徳２０の爪片２１の底面に設けた凹部２１Ｂに耐熱性緩衝体２４をねじ止めしたので、緩衝体２４が強く擦られても外れることがなく、安定して緩衝体２４による天板１３の傷付き防止を図ることができ、また緩衝体２４の外れによる五徳２０のガタ付きを招くこともなくなる。またこの緩衝体２４は断熱性シート２５を介してかつ凹部２１Ｂ内の内側側壁２１Ｂ３と点接触または間隙を存して取り付け、広面積での五徳２０と緩衝体２４との接触をなくしたので、五徳２０から緩衝体２４へ熱が伝達するのを低減でき、緩衝体２４の熱による劣化をなくし高耐久性なものにできる。
【００３５】
ちなみに、五徳２０の爪片２１の温度は最高２７０℃にまで達することがあるが、本実施の形態の緩衝体の取付けによれば、緩衝体２４の温度を約５０℃低下した２２０℃程度までしか上昇させないで済み、緩衝体の劣化を十分に防ぐことができる。
【００３６】
図６（ａ）、（ｂ）は他の実施の形態を示すもので、爪片２１の外側面２１Ｃの前記凹部２１Ｂの開口上縁に水切り用の突片２１Ｄを一体に形成し、該突片２１Ｄにより断熱性シート２５を覆うようにした。該突片２１Ｄは緩衝体２４への伝熱を避けるために、緩衝体２４と間隙を開けて設ける。これにより、爪片２１に垂れた煮汁の量が多くても、煮汁は突片２１Ｄを伝わって下に落下するので、爪片２１の外側面２１Ｃから凹部２１Ｂ内に回り込むことがなくなり、断熱性シート２５が煮汁により濡れることがない。
【００３７】
また耐熱性緩衝体２４の下面には、図６（ｃ）に示すように、四隅に突起２７を設ける。突起２７は緩衝体２４と一体成形により形成することができる。これにより、上記図６（ｂ）に示すように、緩衝体２４の下面の突起２７を天板１３に当接させて、五徳２０を天板１３に対し滑りづらくできる他、天板１３からの熱の緩衝体２４への伝達を低減することができ、緩衝体２４の熱による劣化を防止する効果をさらに向上することができる。
【００３８】
以上の実施の形態では、五徳２０の凹部２１Ｂは平面視矩形としたが、適宜形状とすることができる。五徳２０は爪片２１の脚部２１Ａで天板１３に着地するタイプなので、爪片２１の底面に脚部の位置で凹部を設けて緩衝体を２４を取り付けたが、天板１３の開口周縁部１３ｃの保護リング１６の外側で五徳枠を天板１３に着地させるタイプの五徳では、五徳枠の底面に凹部を設けて緩衝体を取り付ければよい。
【００３９】
またガラス天板を用いたドロップイン式のコンロの五徳を例にとって説明したが、天板はアルミ等の金属板を用いたものでもよい。またコンロはドロップインタイプのものに限られず、上置きタイプでもよい。ガスバーナは外炎式、内炎式のいずれであってもよい。
【００４０】
【発明の効果】
以上の説明から明らかなように、本発明によれば、下面に取り付けた耐熱性の緩衝体の外れをなくすと共に、緩衝体への熱の伝達を低減して緩衝体の耐久性を高めた五徳を提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to five virtues used in a stove.
[0002]
[Prior art]
In a stove such as a gas stove, a protective layer such as an enamel or fluorine coating is often provided on the top surface of the top plate to prevent boiled juice from adhering to the top plate that covers the opening on the top surface of the stove body. Is called. In addition, iron virtues are placed on the top plate, but when rubbed by the virtues, the top surface of the top plate is damaged. In particular, the top plate provided with a protective layer on the top surface is easily scratched.
[0003]
Therefore, there has been known one in which a recess is provided on the bottom of the virtues and attached by inserting a heat-resistant buffer (packing) into the recess to prevent the top plate from being damaged by rubbing the virtues (for example, , See Patent Document 1).
[0004]
[Patent Document 1]
Japanese Patent Laid-Open No. 10-300104 (bush 45 in FIG. 1)
[0005]
[Problems to be solved by the invention]
However, if the shock absorber is inserted into the recess on the bottom of the virtues, it will easily come off when the shock absorber is rubbed strongly, and the detachment of the shock absorber will not prevent the top plate from being damaged. Invite you. In addition, the iron virtues easily transmit heat, and the buffer body may be deteriorated or melted by the heat transfer, so that the buffer body lacks durability and may cause it to come off.
[0006]
Accordingly, an object of the present invention is to improve the durability by eliminating the detachment of the buffer body and preventing the buffer body from being deteriorated by heat in the five virtues having a heat-resistant buffer body on the bottom surface.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention is a virtues used in a stove, wherein a heat-resistant buffer is attached to a recess formed on the bottom surface of the virtues, and a lower portion thereof is projected from the bottom surface. The shock absorber is attached by a screw with a head sunk in a recessed portion provided on the bottom surface of the shock absorber with a heat insulating material interposed on the top surface of the recess.
[0008]
The virtues consist of a plurality of claw pieces and a frame connecting them, and the bottom of the virtues where the recesses are formed may be either the bottom of the claw pieces or the bottom of the frame.
[0009]
In the present invention, since the heat-resistant buffer is screwed to the recess provided on the bottom of the virtues, the buffer does not come off even if the buffer is rubbed strongly, and the top can be stably prevented from being damaged by the buffer. It is also possible to avoid the play of virtues due to the detachment of the buffer. In addition, since the shock absorber is attached to the concave portion of the bottom of the virtues via a heat insulating material, it is possible to reduce the transmission of the heat of the virtues to the shock absorber and to prevent deterioration due to the heat of the shock absorbers and to make it highly durable.
[0010]
According to the present invention, the buffer body can be attached to the concave portion at a distance from the inner side wall of the concave portion or in point contact. Thereby, the heat transfer to a buffer body can be reduced more and the deterioration prevention by the heat | fever of a buffer body can be improved. If the contact with the inner side wall is a point contact, the buffer body is positioned in the recess. In particular, the buffer body is positioned without rotating during screwing or the like.
[0011]
In addition, a housing portion that houses the lower portion of the heat insulating material may be formed on the upper surface of the buffer body, and the lower portion of the heat insulating material housed in the housing portion may be shaped so as not to rotate against the inner side wall of the housing portion. If it does in this way, it will become difficult to see the heat insulating material attached to the recessed part from the outside, an appearance will not be impaired, and it can prevent that a heat insulating material shifts | deviates from a buffer body at the time of attachment of a buffer body.
[0012]
Further, a top surface accommodating portion that accommodates the upper portion of the heat insulating material is formed on the top surface of the concave portion, and the upper portion of the heat insulating material accommodated in the top surface accommodating portion does not rotate against the inner side wall of the top surface accommodating portion. can do. This also makes it difficult for the heat insulating material attached to the concave portion to be seen from the outside, so that the appearance is not impaired, and prevents the heat insulating material from being displaced in the concave portion when the shock absorber is attached. it can.
[0013]
In addition, a plurality of protrusions can be provided on the lower surface of the side wall forming the recessed portion on the bottom surface of the buffer body. As a result, the virtues can be made difficult to slide with respect to the top plate, and the transmission of heat from the top plate to the buffer body can be reduced, and the effect of preventing deterioration of the buffer body due to heat can be further improved.
[0014]
In one aspect of the present invention, the five virtues include a plurality of radial claw pieces and a frame body connecting the claw pieces in the radial direction, and the recess formed on the bottom surface of the claw pieces is in the longitudinal direction of the claw pieces. It was a notch groove which both sides opened, and a water drain part was provided in the opening upper edge of this notch groove. If a drainer is provided, even if there is a large amount of boiled soup hanging on the nail piece, the broth will fall down along the drainage part, so it will not wrap around the recess from the outer surface of the nail piece, and heat insulation material Will not get wet by the broth.
[0015]

At this time, the upper surface 24U of the buffer body 24 is not in contact with the top surface 21B1 of the recess 21 by the heat insulating sheet 25. Further, since the lower portion 24K of the buffer body 24 protrudes from the bottom surface of the leg portion 21A of the claw piece 21 by a height H, even when the virtues 20 are placed on the top board 13, it is the buffer body 24 that the virtues 20 come into contact with. The top plate 13 is not damaged.
[0024]
Further, the buffer body 24 is formed in a small rectangular shape that does not contact the inner side wall 21B3 in order to eliminate heat transfer due to contact with the inner side wall 21B3 of the recess 21B of the claw piece 21, and a gap is formed between the inner side wall 21B3 and the inner side wall 21B3. Installed.
[0025]
If the buffer 24 is in point contact with the inner side wall 21B3, there is almost no heat transfer from the five virtues. Therefore, the buffer 24 is in point contact with the inner side wall 21B3, for example, as shown by a broken line in FIG. In addition, the inner side wall 21B3 has an arcuate shape, and only a corner portion of the rectangular buffer 24 is in point contact with the inner side wall 21B3, or as shown in FIG. 5C, the inner side wall 21B3 protrudes inward from the inner side wall 21B3. The protrusion 28 is formed to make point contact, and as shown in FIG. 5D, the protrusion 29 protruding outward from the side surface of the buffer 24 is formed to make point contact between the buffer 24 and the inner side wall 21B3. You may make it do. By doing so, the buffer body 24 is positioned in the recess 21B. In particular, the buffer body 24 is positioned without rotating during screwing.
[0026]
As the heat-resistant buffer 24, for example, silicon rubber (heat-resistant temperature 300 ° C.) was used, and as the heat-insulating sheet 25, a ceramic wool nonwoven fabric was used.
[0027]
Preferably, a rectangular accommodating portion 24A is formed on the upper surface of the buffer body 24, and the lower half portion of the heat insulating sheet 25 is accommodated and supported by the accommodating portion 24A. If it does in this way, it will become difficult to see the heat insulation sheet 25 attached to the recessed part 21B from the outside, an appearance will not be impaired, and when the buffer body 24 is attached, the heat insulation sheet 25 will be displaced from the buffer body 24. Can be prevented.
[0028]
Further, in this embodiment, the accommodating portion 24A on the upper surface of the shock absorber 24 has a side wall 24A1 forming the accommodating portion 24A on the side located at the openings on both sides of the concave portion 21B, that is, on the both side surfaces 21C side of the leg portion 21A. The side of the recess 21B facing the pair of inner side walls 21B3 is cut out to form a cutout 24A2.
[0029]
In addition, positioning of the heat insulating sheet 25 to the buffer body 24 is performed by positioning the side surface 25A1 of the heat insulating sheet 25 adjacent to the side wall 24A1 constituting the accommodating portion 24A for the heat insulating sheet 25, thereby insulating the heat. The sheet 25 is prevented from rotating inside the accommodating portion 24A.
[0030]
In addition, as shown by a dotted line in FIG. 5A, the top surface accommodating portion 21B2 that accommodates the heat insulating sheet 25 is formed on the top surface 21B1 of the recess 21B, and the heat insulating sheet accommodated in the top surface accommodating portion 21B2 is formed. The upper part of 25 can be made into the shape which does not turn against the inner side wall of a top surface accommodating part.
[0031]
Also by doing in this way, the heat insulating sheet 25 attached to the concave portion 21B becomes difficult to be seen from the outside, the appearance is not impaired, and when the shock absorber 24 is attached, the heat insulating sheet 25 is displaced in the concave portion 21B. Can be prevented.
[0032]
Further, the recessed portion 24B on the lower surface of the buffer body 24 has a side wall 24B1 forming the recessed portion 24B left on the same side as the notched portion 24A2 of the accommodating portion 24A, and is notched on the side facing the notched portion 24A2. If formed in the notch 24B2, the shape of the buffer body 24 can be balanced, and deformation of the buffer body 24 when the screw 26 is tightened can be prevented. 24C is a hole for the screw 26.
[0033]
Note that the accommodating portion 24A is a groove-shaped accommodating portion between the opposing side walls 24A1, but may be a concave portion that is surrounded by the side walls 24A1. Moreover, although the recessed part 24B was also made into the groove-shaped recessed part by the notch part 24B2, it can also be made into the recessed part by which 4 sides were enclosed by side wall 24B1.
[0034]
The virtues of the present embodiment are configured as described above, and the heat-resistant cushioning body 24 is screwed to the concave portion 21B provided on the bottom surface of the claw piece 21 of the virtues 20, so that even if the cushioning body 24 is rubbed strongly, it is detached. Therefore, the top plate 13 can be stably prevented from being damaged by the buffer body 24, and the play of the five virtues 20 due to the detachment of the buffer body 24 can be prevented. In addition, since the buffer body 24 is attached via the heat insulating sheet 25 and with the inner side wall 21B3 in the recess 21B with a point contact or gap, the contact between the virtues 20 and the buffer body 24 in a large area is eliminated. Transfer of heat from the virtues 20 to the buffer body 24 can be reduced, and deterioration of the buffer body 24 due to heat can be eliminated to make it highly durable.
[0035]
Incidentally, the temperature of the claw piece 21 of Gotoku 20 may reach a maximum of 270 ° C. However, according to the mounting of the buffer body of the present embodiment, the temperature of the buffer body 24 is lowered to about 220 ° C. by about 50 ° C. It is only necessary to raise it, and the deterioration of the buffer can be sufficiently prevented.
[0036]
6 (a) and 6 (b) show another embodiment. A draining protrusion 21D is integrally formed on the upper edge of the opening of the recess 21B of the outer surface 21C of the claw piece 21, and the protrusion The heat insulating sheet 25 was covered with the piece 21D. In order to avoid heat transfer to the buffer 24, the protrusion 21D is provided with a gap from the buffer 24. Thereby, even if there is much quantity of the broth drooping on the nail piece 21, since the broth falls down along the protrusion piece 21D, it does not go around into the recessed part 21B from the outer surface 21C of the nail piece 21, and is heat-insulating. The sheet 25 is not wetted by the broth.
[0037]
Further, as shown in FIG. 6C, protrusions 27 are provided at the four corners on the lower surface of the heat resistant buffer 24. The protrusion 27 can be formed by integral molding with the buffer body 24. As a result, as shown in FIG. 6B, the protrusions 27 on the lower surface of the buffer body 24 can be brought into contact with the top plate 13 to make it difficult for the virtues 20 to slide with respect to the top plate 13. Transmission of heat to the buffer body 24 can be reduced, and the effect of preventing the buffer body 24 from being deteriorated by heat can be further improved.
[0038]
In the above embodiment, the recess 21 </ b> B of the virtues 20 is rectangular in plan view, but can be appropriately shaped. Since Gotoku 20 is a type that lands on the top plate 13 with the leg portion 21A of the claw piece 21, a recess 24 is provided at the position of the leg portion on the bottom surface of the claw piece 21 and a buffer 24 is attached. In the type of virtues where the virtuosity frame is landed on the top plate 13 outside the protective ring 16 of the portion 13c, a buffer may be attached by providing a recess on the bottom surface of the virtuosity frame.
