Description

本発明は、こん炉本体とこん炉本体上に設置される天板を備えたガスこん炉に関する。 The present invention relates to a gas furnace equipped with a furnace body and a top plate installed on the furnace body.

従来、こん炉本体と天板で構成されるガスこん炉として、例えば特許文献１に示すものが知られている。このガスこん炉はいわゆるドロップインタイプのガスこん炉であって、キッチン台のカウンターに形成した孔にこん炉本体を落とし込み、天板をこん炉本体上に取り付けて天板をカウンター上に配置する。 Conventionally, as a gas furnace comprising a furnace body and a top plate, for example, the one shown in Patent Document 1 is known. This gas furnace is a so-called drop-in type gas furnace. The main body of the furnace is dropped into a hole formed in the counter of the kitchen table, the top plate is attached on the main body of the furnace, and the top plate is placed on the counter. .

上記ガスこん炉は、天板の前部の下面部に前方に突出する引掛部を形成し、こん炉本体の上面部に後方に開口する引掛穴を形成している。天板をこん炉本体に取り付けるには、天板を前下がりとなるよう傾け、該天板の引掛部をこん炉本体の引掛穴に引っ掛け、次に、天板を後部が下方に移動するよう引掛け部を支点に回動してこん炉本体上に載置し、この後、天板の後部を螺子によりこん炉本体に固着する。このように取付けた天板は、前部が浮き上がったときに引掛部が引掛穴の上縁部に引っ掛かり、これ以上の浮き上がりが防止される。
特開平１１−２８１０６８号公報 In the gas furnace, a hooking portion protruding forward is formed on the lower surface portion of the front portion of the top plate, and a hooking hole opening rearward is formed on the upper surface portion of the furnace main body. To attach the top plate to the furnace body, tilt the top plate so that it falls downward, hook the hook of the top plate into the hook hole of the furnace body, and then move the top plate downwards The hook is rotated around the fulcrum and placed on the furnace main body, and then the rear part of the top plate is fixed to the furnace main body with screws. When the front part is lifted, the hooking part is hooked on the upper edge part of the hooking hole when the front part is lifted, and further lifting is prevented.
Japanese Patent Application Laid-Open No. 11-281068

ところで、上記のように天板が引掛部を支点に回動するには、引掛部を引掛穴に若干の遊びを持って挿入する必要があり、このために天板をこん炉本体上に取り付けた状態では、引掛部と引掛穴の上縁部との間に隙間を形成する必要がある。従って、こん炉本体に取り付けた天板の前部は前記隙間に相当する距離だけ浮き上がることがあり、このように天板の前部が浮き上がった場合、天板の前部下面とカウンターの上面との間の隙間から、こんろ本体側にごみや煮汁等が入りやすく、ガスこん炉の故障の原因となる。 By the way, in order for the top plate to rotate with the hook portion as a fulcrum as described above, it is necessary to insert the hook portion into the hook hole with some play, and for this purpose, the top plate is mounted on the furnace body. In this state, it is necessary to form a gap between the hook portion and the upper edge portion of the hook hole. Therefore, the front part of the top plate attached to the furnace body may be lifted by a distance corresponding to the gap, and when the front part of the top plate is lifted in this way, the front lower surface of the top plate and the upper surface of the counter Garbage, broth, etc. are likely to enter the stove body from the gap between them, causing the gas stove to malfunction.

なお、天板をこん炉本体上に載置したときに、こん炉本体のフランジ部を天板によって余裕を持って覆い隠せるようにするために、引掛部を天板の前端部より後方寄りに設けることも考えられるが、この場合は、天板を前下がりに傾斜させて引掛部を引掛穴に差し込むときに天板の前端がカウンターの上面に接触するため、現実には採用できない。 In addition, when the top plate is placed on the furnace body, the hook part should be placed closer to the rear than the front end of the top board so that the flange part of the furnace body can be covered with a margin by the top board. However, in this case, the front end of the top plate contacts the upper surface of the counter when the top plate is inclined forward and the hook portion is inserted into the hook hole.

また、上記引掛部は天板の下面に設けたものであるため、天板を持つ作業者が引掛部を視認し難く、このため引掛部を引掛穴に位置合わせして引っ掛ける作業が難しいという問題もある。 In addition, since the hooking portion is provided on the lower surface of the top plate, it is difficult for an operator having the top plate to visually recognize the hooking portion, so that it is difficult to align the hooking portion with the hooking hole and hook it. There is also.

Between the pair of restricting portions 31, the gap in the left-right direction is substantially the same as the left-right width of the upper portion of the side piece portion 17, and a gap that allows passage through the insertion portion 16 is formed.

また、縦片１０ｂにおける被係合孔部３０の下方部の左右両側には後方に突出する当たり部３２を形成している。一対の当たり部３２の間には、左右方向の間隔が沿片部１７の上部の左右幅よりも小さく且つ幅狭部３３の左右幅よりも若干大きい隙間が形成されており、該隙間には幅狭部３３を通過可能としてある。また、この隙間には、沿片部１７の上部は通過できないようになっている。なお、各当たり部３２と前述の各規制部３１は縦片１０ｂの一部を切り起こして形成される。 Moreover, the contact part 32 which protrudes back is formed in the right-and-left both sides of the downward part of the to-be-engaged hole part 30 in the vertical piece 10b. Between the pair of contact portions 32, a gap is formed in which the gap in the left-right direction is smaller than the left-right width of the upper portion of the side piece portion 17 and slightly larger than the left-right width of the narrow portion 33, The narrow portion 33 can be passed. Further, the upper portion of the side piece 17 cannot pass through this gap. In addition, each contact part 32 and each above-mentioned control part 31 cut and raise a part of vertical piece 10b.

各被係合体１２を前フレーム１０に取り付けるには、挿入部１６を両規制部３１の間に配置し、ここから、挿入部１６を下方に移動して挿入孔２９に挿入する。このとき、挿入部１６は一対の規制部３１により左右方向の移動が規制されるので、挿入孔２９に挿入部１６をスムーズに挿入できる。 In order to attach each engaged body 12 to the front frame 10, the insertion portion 16 is disposed between the two restriction portions 31, and from here, the insertion portion 16 is moved downward and inserted into the insertion hole 29. At this time, since the insertion portion 16 is restricted from moving in the left-right direction by the pair of restriction portions 31, the insertion portion 16 can be smoothly inserted into the insertion hole 29.

挿入部１６は、その下端部が挿入孔２９より下方に突出し、両側のストッパ部３４の下端面が対応する当たり部３２の上面に当たり、且つ、係合突起１８が被係合孔部３０に対応する位置に移動するまで挿入され、このように挿入することで、前方に突出する係合突起１８は被係合孔部３０に係合する。 The insertion portion 16 has a lower end projecting downward from the insertion hole 29, the lower end surfaces of the stopper portions 34 on both sides contact the upper surface of the corresponding contact portion 32, and the engagement protrusion 18 corresponds to the engaged hole portion 30. It is inserted until it moves to the position to be engaged, and by inserting in this way, the engagement protrusion 18 protruding forward is engaged with the engaged hole 30.

この取り付け状態にあっては、挿入孔２９に挿入部１６が挿入され、且つ、一対の規制部３１の間に沿片部１７の上部が位置し、且つ、一対の当たり部３２の間に幅狭となった沿片部１７の下端部が位置して、被係合体１２の横方向の移動が規制される。また、各ストッパ部３４が当たり部３２に当たって下方への移動が規制される。 In this attached state, the insertion portion 16 is inserted into the insertion hole 29, the upper portion of the side piece portion 17 is located between the pair of restricting portions 31, and the width between the pair of contact portions 32 is wide. The lower end portion of the narrowed strip portion 17 is positioned, and the lateral movement of the engaged body 12 is restricted. Moreover, each stopper part 34 contacts the contact part 32, and a downward movement is controlled.

また、挿入部１６の斜片部５１が挿入孔２９の後方壁部を構成する部位４４の前面に弾接し、且つ、係合突起１８の上端面が被係合孔部３０の水平な上縁面に係合して、上方への移動が規制され、これにより、各被係合体１２の取付部１３は前フレーム１０にしっかりと固定される。 Further, the slant piece 51 of the insertion portion 16 is in elastic contact with the front surface of the portion 44 constituting the rear wall portion of the insertion hole 29, and the upper end surface of the engagement protrusion 18 is the horizontal upper edge of the engagement hole portion 30. By engaging with the surface, the upward movement is restricted, whereby the attachment portion 13 of each engaged body 12 is firmly fixed to the front frame 10.

ここで、係合突起１８の上端面は切溝形成時の切断面で構成されるため、同じく水平な切断面で構成された被係合孔部３０の上縁部の下面にしっかりと係合させることができる。従って、挿入部１６が挿入孔２９から上方に抜け出ることを確実に防止できる。 Here, since the upper end surface of the engagement protrusion 18 is formed by a cut surface when the kerf is formed, the engagement protrusion 18 is firmly engaged with the lower surface of the upper edge portion of the engaged hole portion 30 which is also formed by a horizontal cut surface. Can be made. Therefore, it is possible to reliably prevent the insertion portion 16 from coming out of the insertion hole 29 upward.

一方、係合体１１は折曲加工した金属板からなり、トッププレート３７の前部の下面両側に取り付けられる。 On the other hand, the engaging body 11 is made of a bent metal plate and is attached to both sides of the lower surface of the front portion of the top plate 37.

各係合体１１は、トッププレート３７の下面に沿って取り付けられる天板側固定部４５と、天板側固定部４５から下方に突出した本体側固定部１９とで構成される。 Each engagement body 11 includes a top plate side fixing portion 45 attached along the lower surface of the top plate 37 and a main body side fixing portion 19 protruding downward from the top plate side fixing portion 45.

本体側固定部１９は、天板３の前端よりやや後方に控えた位置から下方に向けて突出している。本体側固定部１９は、天板側固定部４５の後端から垂下した左右方向に平行な垂下片部４６と、垂下片部４６の両側縁及び下縁の夫々から後方に突出する側縁片部４７及び下縁片部４８で構成される。 The main body side fixing portion 19 protrudes downward from a position slightly behind the front end of the top plate 3. The main body side fixing portion 19 includes a hanging piece portion 46 parallel to the left and right direction that hangs down from the rear end of the top plate side fixing portion 45, and a side edge piece that protrudes rearward from the both side edges and the lower edge of the hanging piece portion 46. It comprises a portion 47 and a lower edge piece 48.

垂下片部４６の上部には下縁面が水平となった係合孔部４９を形成してあり、本例では本体側固定部１９の係合孔部４９よりも下方に位置する部分を係合部１５としている。また、両側の側縁片部４７の下端は下縁片部４８の両端に接続してあり、これにより本体側固定部１９は補強され、係合体１１の係合部１５は被係合体１２と比べて変形し難いものとなっている。 An engagement hole portion 49 having a horizontal lower edge surface is formed in the upper portion of the hanging piece portion 46. In this example, a portion located below the engagement hole portion 49 of the main body side fixing portion 19 is engaged. The joint 15 is used. Further, the lower ends of the side edge piece portions 47 on both sides are connected to both ends of the lower edge piece portion 48, whereby the main body side fixing portion 19 is reinforced, and the engaging portion 15 of the engaging body 11 is connected to the engaged body 12. It is hard to be deformed.

次に、上記天板３のこん炉本体２への取り付け方法につき説明する。 Next, a method for attaching the top plate 3 to the furnace body 2 will be described.

天板３をカウンター４に懸下してあるこん炉本体２に取り付ける場合、まず、図８に示すように天板３を略水平にし、各バーナー孔３５と対応するガスバーナー７との位置を合わせて取り付け位置の直上に配置する。これにより、係合体１１の係合部１５は被係合体１２の被係合部１４の当接面２７の上方に位置することとなる。 When the top plate 3 is attached to the furnace body 2 suspended from the counter 4, first, the top plate 3 is made substantially horizontal as shown in FIG. 8, and the positions of the gas burners 7 corresponding to the respective burner holes 35 are set. Combine them and place them directly above the mounting position. Thereby, the engaging part 15 of the engaging body 11 is positioned above the contact surface 27 of the engaged part 14 of the engaged body 12.

ここから、天板３を各バーナー孔３５に対応するガスバーナー７が挿入されるよう位置合わせしながら水平状態を維持しつつ略鉛直下向きに移動し、該天板３をこん炉本体２のフランジ部９上に載置すると共に、図３に示すように天板３のプレート枠３６の周縁部をシール材３９を介してカウンター４上に載置する。これにより係合体１１は以下のように被係合体１２に係合される。 From here, the top plate 3 is moved substantially vertically downward while maintaining the horizontal state while aligning the gas burners 7 corresponding to the respective burner holes 35 to be inserted, and the top plate 3 is moved to the flange of the furnace body 2. As shown in FIG. 3, the peripheral portion of the plate frame 36 of the top plate 3 is placed on the counter 4 via the sealing material 39. Thereby, the engaging body 11 is engaged with the engaged body 12 as follows.

上記天板３の略鉛直下向きの移動時には、まず天板３と共に略鉛直下向きに移動する係合体１１の係合部１５の下端部が、被係合体１２の被係合部１４の当接面２７に当接する。 When the top plate 3 moves substantially vertically downward, first, the lower end portion of the engaging portion 15 of the engaging body 11 that moves substantially vertically downward together with the top plate 3 is the contact surface of the engaged portion 14 of the engaged body 12. 27 abuts.

天板３が更に略鉛直下向きに移動して、係合部１５の下端部によって当接面２７が下方に押圧されると、被係合体１２は弾性変形して被係合部１４が突出方向とは反対側である前側に移動し、係合部１５が被係合体１２の当接面２７及び立上片部２３の後面に沿って下方に移動する。 When the top plate 3 is further moved substantially vertically downward and the contact surface 27 is pressed downward by the lower end portion of the engaging portion 15, the engaged body 12 is elastically deformed and the engaged portion 14 is projected. The engaging portion 15 moves downward along the contact surface 27 of the engaged body 12 and the rear surface of the rising piece portion 23.

更に天板３が略鉛直下向きに移動して係合体１１が下方に移動すると、係合部１５が被係合部１４を乗り越えると共に係合孔部４９が被係合部１４に対応する位置に配され、これにより被係合体１２は弾性復帰して被係合部１４が後側に移動し、該被係合部１４が係合孔部４９に嵌まり込む。 Further, when the top plate 3 is moved substantially vertically downward and the engaging body 11 is moved downward, the engaging portion 15 gets over the engaged portion 14 and the engaging hole portion 49 is in a position corresponding to the engaged portion 14. Accordingly, the engaged body 12 is elastically restored, the engaged portion 14 moves to the rear side, and the engaged portion 14 is fitted into the engaging hole portion 49.

この取付状態では、係合部１５（係合孔部４９の下縁部）が、被係合部１４の下面前端部（横片部２２の下面前端部）に係合される。これにより係合体１１は被係合体１２に上方及び左右方向に移動不能となるよう係合される。 In this attached state, the engaging portion 15 (the lower edge portion of the engaging hole portion 49) is engaged with the lower surface front end portion of the engaged portion 14 (the lower surface front end portion of the horizontal piece portion 22). As a result, the engaging body 11 is engaged with the engaged body 12 so as not to move upward and left and right.

また、上記のように係合部１５が被係合部１４に係合した時点で、天板３はこん炉本体２のフランジ部９上に載置され、また、天板３のプレート枠３６は前記シール材３９を介してカウンター４の上面に載置され、天板３は下方にも移動不能となる。 Further, when the engaging portion 15 is engaged with the engaged portion 14 as described above, the top plate 3 is placed on the flange portion 9 of the furnace body 2, and the plate frame 36 of the top plate 3. Is placed on the upper surface of the counter 4 via the sealing material 39, and the top plate 3 cannot move downward.

そして、この状態で、前記螺子により天板３の後部をこん炉本体２に螺子止めすることにより、天板３のこん炉本体２への取り付けが完了する。 In this state, the rear portion of the top plate 3 is screwed to the furnace body 2 with the screws, whereby the attachment of the top plate 3 to the furnace body 2 is completed.

以上、説明した本例のガスこん炉１は、天板３をこん炉本体２に取り付けるにあたって、天板３を略鉛直下向きに移動してこん炉本体２上に載置するだけで、係合体１１の係合部１５を被係合体１２の被係合部１４上に当接させ、係合部１５により被係合部１４を下側に押し込んで被係合体１２を弾性変形させ、係合部１５を被係合部１４を乗り越えさせて被係合部１４の下面前端部に係合させることができる。従って、天板３をこん炉本体２に取り付けた状態において、被係合部１４の下面に係合部１５を当接でき、天板３の前部の浮き上がりを確実に防止できる。 As described above, the gas furnace 1 of the present example described above is an engagement body in which, when the top plate 3 is attached to the furnace body 2, the top plate 3 is moved substantially vertically downward and placed on the furnace body 2. 11 engaging portions 15 are brought into contact with the engaged portions 14 of the engaged bodies 12 and the engaged portions 15 are pushed downward by the engaging portions 15 to elastically deform the engaged bodies 12 to be engaged. The portion 15 can get over the engaged portion 14 and can be engaged with the lower surface front end portion of the engaged portion 14. Therefore, in a state where the top plate 3 is attached to the furnace body 2, the engaging portion 15 can be brought into contact with the lower surface of the engaged portion 14 and the front portion of the top plate 3 can be reliably prevented from being lifted.

また、天板３の各バーナー孔３５の位置を対応するガスバーナー７に合わせることで、係合体１１の係合部１５と、被係合体１２の被係合部１４との位置を合わせることができ、視認し難い天板３の下面に設けた係合体１１を被係合体１２に容易に係合することができる。 Further, by aligning the position of each burner hole 35 of the top plate 3 with the corresponding gas burner 7, the positions of the engaging portion 15 of the engaging body 11 and the engaged portion 14 of the engaged body 12 can be aligned. The engaging body 11 provided on the lower surface of the top plate 3 that is difficult to visually recognize can be easily engaged with the engaged body 12.

さらに、本例の天板３は、天板３の前部下面に設けた係合体１１の係合部１５を、被係合体１２の上部から後方に向けて突出した被係合部１４の下面前端部に係合すると共に、天板３の後部を前記各螺子によりこん炉本体２に着脱自在に取り付け、この状態でこん炉本体２上に設置される。 Further, the top plate 3 of the present example is such that the engaging portion 15 of the engaging body 11 provided on the lower surface of the front portion of the top plate 3 protrudes rearward from the upper portion of the engaged body 12 to the lower surface of the engaged portion 14. In addition to engaging with the front end portion, the rear portion of the top plate 3 is detachably attached to the furnace main body 2 by the screws, and is installed on the furnace main body 2 in this state.

このため、上記のように天板３をこん炉本体２に設置した状態で、天板３の前部に上向きの力が加わったとしても、天板３の前部下方に位置する係合部１５は、係合した被係合体１２の横片部２２と縦片部２１とでなす角部を、螺子で取り付けられた天板３の後部を支点にして略鉛直上方に向けて押圧する。このため、係合部１５の係合が外れ難く、天板３の前部の浮き上がりを確実に防止できる。 Therefore, even when an upward force is applied to the front portion of the top plate 3 with the top plate 3 installed on the furnace body 2 as described above, the engaging portion located below the front portion of the top plate 3. 15 presses the corner portion formed by the horizontal piece portion 22 and the vertical piece portion 21 of the engaged body 12 engaged with the rear portion of the top plate 3 attached with screws toward a substantially vertical upper side. For this reason, it is difficult to disengage the engaging portion 15, and it is possible to reliably prevent the front portion of the top plate 3 from being lifted.

また、上記天板３はメンテナンス時等にこん炉本体２から取り外す場合があり、この場合、前記各螺子を取り外し、係合体１１と被係合体１２の係合を解除するのだが、本例では以下のように天板３の取り外しを行うことで、係合体１１と被係合体１２の係合を容易に解除できる。 Further, the top plate 3 may be removed from the furnace main body 2 during maintenance or the like. In this case, the screws are removed, and the engagement between the engaging body 11 and the engaged body 12 is released. By removing the top plate 3 as described below, the engagement between the engaging body 11 and the engaged body 12 can be easily released.

即ち、天板３を取り外すには、まず前記各螺子を取り外して天板３の後部を移動可能とし、この後、係合体１１を被係合体１２に係合したまま、カウンター４上にシール材３９を介して載せた天板３の前端部を支点にして天板３の後部を持ち上げる。 That is, in order to remove the top plate 3, first, the screws are removed so that the rear portion of the top plate 3 can be moved, and then the sealing member is placed on the counter 4 while the engaging body 11 is engaged with the engaged body 12. The rear part of the top plate 3 is lifted with the front end portion of the top plate 3 placed via 39 as a fulcrum.

このようにすると、係合部１５により横片部２２が後斜め上方に向けて押し上げられ、被係合体１２が弾性変形して、被係合部１４が縦片部２１の上端部を支点にして前側に回動し、これにより係合部１５が被係合部１４から外れる。 If it does in this way, the horizontal piece part 22 will be pushed up back diagonally upward by the engaging part 15, the to-be-engaged body 12 will elastically deform, and the to-be-engaged part 14 will use the upper end part of the vertical piece part 21 as a fulcrum. Then, the engaging portion 15 is disengaged from the engaged portion 14.

ここで、前記被係合体１２が前側に撓むにつれて、係合部１５の被係合部１４に対する係合位置は横片部２２の前端部から徐々に後側に移動することとなる。このため係合部１５から被係合部１４に加わる縦片部２１の上端部を支点にしたモーメントは徐々に増していくことになる。従って、上記のように、天板３の後部を持ち上げることで、容易に係合部１５と被係合部１４の係合を解除できる。 Here, as the engaged body 12 bends forward, the engaging position of the engaging portion 15 with respect to the engaged portion 14 gradually moves from the front end portion of the lateral piece portion 22 to the rear side. For this reason, the moment about the upper end of the vertical piece 21 applied from the engaging portion 15 to the engaged portion 14 gradually increases. Therefore, as described above, the engagement between the engaging portion 15 and the engaged portion 14 can be easily released by lifting the rear portion of the top plate 3.

また、上記のように天板３をこん炉本体２に取り付けた状態では、図３に示すように天板３の前端部下面がキッチン台のカウンター４の上面と略面一となる。このため、本例のように、天板３の前端部をシール材３９を介してカウンター４上に載置し、天板３の前端部とカウンター４の上面との間から煮汁等が侵入することを確実に防止することできる。 Moreover, in the state which attached the top plate 3 to the furnace main body 2 as mentioned above, as shown in FIG. 3, the front end part lower surface of the top plate 3 becomes substantially flush with the upper surface of the counter 4 of a kitchen stand. For this reason, as in this example, the front end portion of the top plate 3 is placed on the counter 4 via the sealing material 39, and the broth or the like enters between the front end portion of the top plate 3 and the upper surface of the counter 4. This can be reliably prevented.

なお、本例では、係合部１５を被係合部１４上に当接させた状態で、天板３を略鉛直下向きに移動することで、被係合部１４が係合部１５に押圧されて被係合体１２が弾性変形し、係合部１５が被係合部１４を乗り越えて被係合部１４の下面に係合するようにしたが、係合部１５を被係合部１４上に当接させた状態で、天板３を略鉛直下向きに移動することで、係合体１１が弾性変形し、係合部１５が被係合部１４を乗り越えて被係合部１４の下面に係合するものであっても構わない。 In this example, the engaged portion 14 is pressed against the engaging portion 15 by moving the top plate 3 substantially vertically downward while the engaging portion 15 is in contact with the engaged portion 14. Thus, the engaged body 12 is elastically deformed, and the engaging portion 15 gets over the engaged portion 14 and engages the lower surface of the engaged portion 14. When the top plate 3 is moved substantially vertically downward while being in contact with the upper side, the engaging body 11 is elastically deformed, and the engaging portion 15 gets over the engaged portion 14 and the lower surface of the engaged portion 14. It does not matter even if it engages.

さらには、係合体１１は天板３の下面前部に設けたが、天板３の下面における後部や側部に設けても良いものとする。 Furthermore, although the engaging body 11 is provided in the lower surface front part of the top plate 3, it may be provided in the rear part or side part in the lower surface of the top plate 3.
