本発明は、天板の前方域に操作つまみが配設されている上面操作式のガスコンロの操作部防水構造に関する。 The present invention relates to an operation unit waterproofing structure of an upper surface operation type gas stove in which an operation knob is disposed in a front area of a top plate.
図６に示すものは、本体ケース(3)の上方開放部を被覆するガラス天板(30)上に、複数のガスバーナ(21)の加熱部(23)と、その前方域に、ガスバーナ(21)の点火・消火などの操作を行なうための操作つまみ(2)を配設させた上面操作式のガスコンロの一例であり、ガラス天板(30)の周囲は、板金製の外枠(32)で包囲されている（特許文献１参照）。 6 shows a heating part (23) of a plurality of gas burners (21) on a glass top plate (30) covering an upper open part of the main body case (3), and a gas burner (21 ) Is an example of a top-operated gas stove provided with operation knobs (2) for performing operations such as ignition and extinguishing, and the periphery of the glass top plate (30) is an outer frame made of sheet metal (32) (See Patent Document 1).
このものは、図７に示すように、システムキッチンのカウンタートップ(4)に形成された開口(40)に本体ケース(3)を落とし込み、ガラス天板(30)の周縁をカウンタートップ(4)にパッキン(41)を介して載置させてセットされる。
ガラス天板(30)には、ガスバーナ(21)の加熱部(23)を臨ませる開口部が形成されるが、近年、前記開口部から煮こぼれ等が本体ケース(3)内に浸入しないように、加熱部(23)の周囲を閉塞させる構成のものが主流となっている。
このような構成のものでは、ガスバーナ(21)用の開口部から燃焼用空気を取り入れにくく燃焼用空気として不足しがちとなる。
そこで、さらなる燃焼用空気を確保するために、図７の二点鎖線の矢印に示すように、ガラス天板(30)に形成される操作つまみ(2)用の透孔(33)から外部の空気を取り込む構成が採用されている。
As shown in FIG. 7, the main body case (3) is dropped into the opening (40) formed in the countertop (4) of the system kitchen, and the peripheral edge of the glass top plate (30) is placed on the countertop (4). And placed through the packing (41).
The glass top plate (30) is formed with an opening that allows the heating section (23) of the gas burner (21) to face, but in recent years, the spillage or the like from the opening does not enter the main body case (3). In addition, a configuration in which the periphery of the heating unit (23) is closed is the mainstream.
In such a configuration, it is difficult to take in the combustion air from the opening for the gas burner (21), and the combustion air tends to be insufficient.
Therefore, in order to secure further combustion air, as shown by the two-dot chain line arrow in FIG. 7, an external control hole (33) formed on the glass top plate (30) is inserted from the through hole (33). The structure which takes in air is adopted.
透孔(33)には、操作つまみ(2)の軸部(22)が挿通しており、軸部(22)の周囲には環状の空気通路が形成される態様となっていると共に、透孔(33)の周面を被覆するように筒状パッキン(10)が嵌め込まれる。
筒状パッキン(10)は、その胴部外周面から、環状の上フランジ部(11)と下フランジ部(12)が外方へ向って水平に張り出していると共に、上フランジ部(11)の基端部の上方には、延長筒部(13)が延長形成されており、上フランジ部(11)と下フランジ部(12)間に、ガラス天板(30)の透孔(33)の周縁部を挟持させる態様で取り付けられる。
延長筒部(13)の上端と操作つまみ(2)の裏面との間から、筒状パッキン(10)と操作つまみ(2)との間にかけて、所定幅の環状の空気通路(S)が連通しており、この空気通路(S)から燃焼用空気が本体ケース(3)内に取り込み可能となっている。
このものでは、延長筒部(13)によって、ガラス天板(30)の上面に溢れた煮こぼれが透孔(33)から本体ケース(3)内へ浸入するのを防止している。
The shaft (22) of the operation knob (2) is inserted through the through hole (33), and an annular air passage is formed around the shaft (22). A cylindrical packing (10) is fitted so as to cover the peripheral surface of the hole (33).
The cylindrical packing (10) has an annular upper flange part (11) and a lower flange part (12) projecting horizontally outward from the outer peripheral surface of the body part, and the upper flange part (11) An extension tube portion (13) is extended above the base end portion, and the through hole (33) of the glass top plate (30) is formed between the upper flange portion (11) and the lower flange portion (12). It is attached in such a manner as to sandwich the peripheral edge.
An annular air passage (S) with a predetermined width communicates between the upper end of the extension cylinder (13) and the back of the operation knob (2) and between the cylindrical packing (10) and the operation knob (2). Combustion air can be taken into the main body case (3) from the air passage (S).
In this case, the extension tube portion (13) prevents boiled spills overflowing from the upper surface of the glass top plate (30) from entering the main body case (3) through the through holes (33).
しかしながら、ガラス天板(30)上に溢れた煮こぼれ等の液状体を、布巾等で前方（操作つまみ(2)側）に向って勢い良く拭くと、操作つまみ(2)側へ押し寄せる液状体は、図７の実線の矢印に示すように、延長筒部(13)で堰き止められるも、延長筒部(13)に当たった後、操作摘み(2)の裏面側へ跳ね返り、操作摘み(2)の裏面から、筒状パッキン(10)と操作つまみ(2)との隙間から、本体ケース(3)内へ滴下されてしまう。
このように、従来の筒状パッキン(10)では、ガラス天板(30)上に溢れた煮こぼれを本体ケース(3)内に浸入するのを確実に防止することはできない。
However, if the liquid material overflowing on the glass top plate (30) is wiped with a cloth or the like toward the front (operation knob (2) side), the liquid material will be pushed toward the operation knob (2) side. As shown by the solid line arrow in FIG. 7, although it is dammed by the extension cylinder part (13), after hitting the extension cylinder part (13), it bounces back to the back side of the operation knob (2), and the operation knob ( From the back surface of 2), it is dropped into the main body case (3) through the gap between the cylindrical packing (10) and the operation knob (2).
Thus, in the conventional cylindrical packing (10), it is not possible to reliably prevent the spilled spilling over the glass top plate (30) from entering the main body case (3).
本発明は、上記事情に鑑みてなされたものであり、操作つまみ用に天板に設けた透孔からガスバーナの燃焼用空気を取り入れることができるようにすると共に、天板上に溢れた煮こぼれは、前記透孔から本体ケース内に浸入しないようにするガスコンロの操作部防水構造を提供することを課題とする。 The present invention has been made in view of the above circumstances, and enables the combustion air of the gas burner to be taken in from a through hole provided in the top plate for the operation knob, and the spilled overflow on the top plate. An object of the present invention is to provide a waterproof structure for the operating portion of the gas stove so as not to enter the main body case from the through hole.
本発明に係るガスコンロの操作部防水構造は、本体ケースの上面を覆う天板上にガスバーナの点消火を行う操作つまみが配設される上面操作式のガスコンロの操作部防水構造において、
前記天板には、操作つまみを支持する軸部が挿通すると共に空気通路となる透孔が貫通形成され、
前記透孔には、筒状パッキンが内嵌され、
前記筒状パッキンは、天板よりも上方に延長する延長筒部が設けられ、前記延長筒部の上部に環状の返し片が外方へ向って張出形成されていることを特徴とする。
The gas stove operation part waterproof structure of the gas stove according to the present invention is an operation part waterproof structure of the gas stove of the top operation type in which an operation knob for performing the point fire extinguishing of the gas burner is disposed on the top plate covering the upper surface of the main body case.
In the top plate, a shaft portion that supports the operation knob is inserted, and a through-hole serving as an air passage is formed therethrough,
A cylindrical packing is fitted in the through hole,
The cylindrical packing is provided with an extended cylindrical portion extending upward from the top plate, and an annular return piece is formed to project outwardly at an upper portion of the extended cylindrical portion.
このような構成により、操作つまみの軸部と透孔との間に形成された空気通路から外部の空気を本体ケース内に取り込むことができる。又、天板上に溢れた煮こぼれ等の液状体が、布巾等による拭き取りにより操作つまみ側へ勢い良く押し寄せた場合、前記液状体は筒状パッキンの延長筒部に当たった後、上方（操作つまみの裏面側）へ跳ね返るが、その跳ね返りは返し片に当たるため、返し片よりも上方への液状体の飛び散りが阻止される。よって、煮こぼれ等の液状体が筒状パッキンの延長筒部を超えることがない。 With such a configuration, external air can be taken into the main body case from the air passage formed between the shaft portion of the operation knob and the through hole. In addition, when a liquid material such as spilled spills overflowing on the top plate rushes to the operation knob side by wiping with a cloth, etc., the liquid material hits the extended cylindrical portion of the cylindrical packing and then moves upward (operation Bounce back to the back side of the knob, but the bounce hits the return piece, so that the liquid material is prevented from scattering upward from the return piece. Therefore, a liquid material such as boiled oil does not exceed the extended cylindrical portion of the cylindrical packing.
また、本発明に係るガスコンロの操作部防水構造において、前記筒状パッキンは、前記返し片の基端部から環状凸部が上方へ向って延長形成されていることが好ましい。
このような構成とすることにより、操作つまみ側へ流れてきた煮こぼれのうち、筒状パッキンの延長筒部に当たって飛び散った一部が、返し片の上面に付着した場合でも、環状凸部によって、筒状パッキンの内方への浸入は阻止される。よって、本体ケース内への煮こぼれの浸入を確実に阻止することができる。
In the gas stove operation portion waterproofing structure according to the present invention, it is preferable that the cylindrical packing has an annular convex portion extending upward from a base end portion of the return piece.
By adopting such a configuration, among the spills that have flowed to the operation knob side, even if a part of the boiled splatter that hit the extended cylindrical part of the cylindrical packing adheres to the upper surface of the return piece, Intrusion of the cylindrical packing inward is prevented. Therefore, it is possible to reliably prevent the spillage from entering the main body case.
また、本発明に係るガスコンロの操作部防水構造において、前記筒状パッキンは、前記返し片の上面の高さが操作つまみの裏面に形成された凹所の外周縁下端部の高さに略一致されていることが好ましい。
このような構成とすることにより、押し回し式の操作つまみであっても、延長筒部及び返し片が邪魔になることなく操作つまみの押し回し操作が可能となる上に、煮こぼれの本体ケース内への浸入を防止しながら、空気通路も確保することができる。
Further, in the gas stove operation portion waterproof structure according to the present invention, the cylindrical packing has a height of an upper surface of the return piece substantially equal to a height of a lower end portion of an outer peripheral edge of a recess formed on a back surface of the operation knob. It is preferable that
By adopting such a configuration, even if it is a push-type operation knob, the operation knob can be pushed and turned without obstructing the extension cylinder part and the return piece, and the spilled body case An air passage can also be secured while preventing entry into the interior.
また、本発明に係るガスコンロの操作部防水構造において、前記筒状パッキンの返し片は、外方へ向って降下するテーパ状に形成されていることが好ましい。
このような構成とすることにより、煮こぼれ等の液状体が筒状パッキンの延長筒部に当たって跳ね返っても返し片の上面に乗り上げ難くなり、又、仮に、乗り上げた場合でも、煮こぼれ等の液状体は、返し片の傾斜に従って、筒状パッキンの外側に流れていくため、本体ケース内への浸入を確実に防止することができる。
In the gas stove operation portion waterproofing structure according to the present invention, it is preferable that the return piece of the cylindrical packing is formed in a tapered shape that descends outward.
By adopting such a configuration, even if a liquid material such as boiled spills hits the extension cylinder part of the cylindrical packing and bounces back, it becomes difficult to ride on the upper surface of the return piece. Since the body flows to the outside of the cylindrical packing according to the inclination of the return piece, the body can be reliably prevented from entering the main body case.
以上のように、本発明によれば、操作つまみの軸部と筒状パッキンとの間に形成される空気通路から、ガスバーナの燃焼用空気を取り込むことが出来るから、ガスバーナ用の開口部から燃焼用空気を取り込むことが出来ない構成の機種であっても、燃焼用空気が不足することがない。
又、天板上に溢れさせた煮こぼれが操作つまみに向って流れてきても、その流れは筒状パッキンの延長筒部で堰き止めることができる上に、延長筒部に当たった後の跳ね返りは、延長筒部の上端近傍に設けられた返し片によってそれより上方への飛散を阻止することができるから、透孔からの煮こぼれ等が本体ケースへ浸入する不都合を確実に防止することができる。
このように、操作つまみ用に設けた透孔から、十分な燃焼用空気を本体ケース内へ取り込むことが出来る上に、透孔から煮こぼれ等が本体ケース内に入り込む不都合を確実に防止することが出来る。
As described above, according to the present invention, the combustion air for the gas burner can be taken in from the air passage formed between the shaft portion of the operation knob and the cylindrical packing, so that the combustion is performed from the opening for the gas burner. Even if the model is configured so that it cannot take in the combustion air, there is no shortage of combustion air.
In addition, even if the spilled spilled over the top plate flows toward the operation knob, the flow can be blocked by the extension cylinder part of the cylindrical packing and bounces after hitting the extension cylinder part. Since it is possible to prevent upward scattering by the return piece provided in the vicinity of the upper end of the extension cylinder portion, it is possible to reliably prevent inconveniences such as spilling from the through hole entering the main body case. it can.
In this way, sufficient combustion air can be taken into the main body case from the through hole provided for the operation knob, and in addition, it is possible to reliably prevent inconveniences such as spilling from the through hole into the main body case. I can do it.
以下に、本発明の実施の形態について添付図面を参照しながら説明する。
本実施形態に係るガスコンロの操作部防水構造は、図６に示したような、天板(30)の後方域にガスバーナの加熱部が、その前方域に操作つまみ(2)が配設されている上面操作式のドロップインコンロに適用したものである。
この種のドロップインコンロは、図１に示すように、上方が開放された矩形箱状の本体ケース(3)と、本体ケース(3)の上方開放部を被覆するガラス製の天板(30)とから構成されてあり、本体ケース(3)はカウンタートップ(4)に設けた開口(40)内に落とし込まれると共に、その上方開放端より外方へ張り出させたフランジ部(31)をパッキン(42)を介してカウンタートップ(4)に係止させている。
又、天板(30)の周縁部は、フランジ部(31)よりも外側にて、パッキン(41)を介して設置される。
尚、天板(30)用のパッキン(41)は、天板(30)の前方端(30a)と、左右両端にのみ設けられてあり、後方端には設けられていない。これにより、天板(30)の後方端とカウンタートップ(4)との間に形成されるパッキン(41)の厚みに相当する隙間から燃焼用空気が取り入れられている。
Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 6, the gas stove operating structure waterproof structure according to the present embodiment has a gas burner heating section in the rear area of the top plate (30) and an operation knob (2) in the front area. This is applied to the top-operated drop-in stove.
As shown in FIG. 1, this type of drop-in stove is composed of a rectangular box-shaped main body case (3) opened upward and a glass top plate (30) covering the upper open portion of the main body case (3). The main body case (3) is dropped into the opening (40) provided in the countertop (4) and protrudes outward from its upper open end (31). Is locked to the countertop (4) through the packing (42).
Further, the peripheral portion of the top plate (30) is installed outside the flange portion (31) via the packing (41).
The packing (41) for the top plate (30) is provided only at the front end (30a) and the left and right ends of the top plate (30), and is not provided at the rear end. Thereby, combustion air is taken in through a gap corresponding to the thickness of the packing (41) formed between the rear end of the top plate (30) and the countertop (4).
本体ケース(3)内には、複数のガスバーナ（図示せず）と、その前方に、各ガスバーナに対応するバルブユニット(20)が収納されている。
バルブユニット(20)からは操作つまみ(2)に連結させる軸部(22)が上方に延びており、軸部(22)に対応する天板(30)の各位置には、軸部(22)が挿通する透孔(33)が形成されている。このものでは、操作つまみ(2)を押し回すことにより、軸部(22)を介して、バルブユニット(20)が駆動させられ、ガスバーナの点火・消火を可能にしている。
In the main body case (3), a plurality of gas burners (not shown) and a valve unit (20) corresponding to each gas burner are housed in front of the gas burners.
A shaft portion (22) connected to the operation knob (2) extends upward from the valve unit (20), and at each position of the top plate (30) corresponding to the shaft portion (22), the shaft portion (22 ) Is inserted therethrough. In this case, by pushing and turning the operation knob (2), the valve unit (20) is driven via the shaft portion (22), and the gas burner can be ignited and extinguished.
尚、図示しないが、ガスバーナの上端の加熱部に対応する所定位置には、前記加熱部を臨ませる開口部が形成されていると共に、開口部のうち、前記加熱部の周囲は汁受け皿によって閉塞されている。
よって、この実施の形態のものでは、天板(30)の後方のカウンタートップとの隙間からと、操作つまみ(2)用の透孔(33)内の、軸部(22)の周囲に設けられる環状の空気通路(S)とから、ガスバーナの燃焼用空気として外部の空気を取り入れる構成となっている。
尚、透孔(33)には、ゴム製の筒状パッキン(1)が嵌め込まれている。
Although not shown, an opening for allowing the heating unit to face is formed at a predetermined position corresponding to the heating unit at the upper end of the gas burner, and the periphery of the heating unit is closed by a juice tray in the opening. Has been.
Therefore, in this embodiment, it is provided around the shaft portion (22) in the through hole (33) for the operation knob (2) from the gap with the counter top behind the top plate (30). From the annular air passage (S), external air is taken in as combustion air for the gas burner.
A rubber cylindrical packing (1) is fitted into the through hole (33).
筒状パッキン(1)は、図１及び図２に示すように、胴部中央から外方に張り出す上フランジ部(11)と、下端部から外方に張り出す下フランジ部(12)と、上フランジ部の基端部から上方へ延びる延長筒部(13)と、延長筒部(13)の上部から外方へ張り出す返し片(14)と、返し片(14)の基端部からさらに上方へ突出させた環状凸部(15)とから構成されている。 As shown in FIGS. 1 and 2, the cylindrical packing (1) includes an upper flange portion (11) projecting outward from the center of the body portion, and a lower flange portion (12) projecting outward from the lower end portion. An extension cylinder part (13) extending upward from the base end part of the upper flange part, a return piece (14) projecting outward from the upper part of the extension cylinder part (13), and a base end part of the return piece (14) It is comprised from the annular convex part (15) protruded further upwards.
筒状パッキン(1)の胴部の外径は透孔(33)の直径に略一致させてあり、上フランジ部(11)と下フランジ部(12)と間の距離は、天板(30)の肉厚に略一致させてある。これにより、筒状パッキン(1)は、透孔(33)の周縁に位置する天板(30)を、上フランジ部(11)と下フランジ部(12)で挟み込む態様で、透孔(33)に密に内嵌する態様で装着することができる。
尚、図１及び図３に示すように、筒状パッキン(1)を透孔(33)に装着させた状態にて、返し片(14)の上面が操作つまみ(2)の裏面に形成された凹所(25)の外周縁下端(24)の高さに略一致するように、延長筒部(13)の高さ及び返し片(14)の突設位置は設定されている。又、返し片(14)の外周径は、外周縁下端(24)との間に、環状凸部(15)を介して空気通路(S)へ連通する一定の隙間が形成される大きさに設定されている。
The outer diameter of the barrel portion of the cylindrical packing (1) is substantially matched to the diameter of the through hole (33), and the distance between the upper flange portion (11) and the lower flange portion (12) is the top plate (30 ). Thus, the cylindrical packing (1) has a shape in which the top plate (30) located at the periphery of the through hole (33) is sandwiched between the upper flange portion (11) and the lower flange portion (12). ) In a mode of being closely fitted inside.
As shown in FIGS. 1 and 3, the top surface of the return piece (14) is formed on the back surface of the operation knob (2) with the cylindrical packing (1) mounted in the through hole (33). The height of the extension tube portion (13) and the protruding position of the return piece (14) are set so as to substantially coincide with the height of the lower edge (24) of the outer peripheral edge of the recess (25). Also, the outer diameter of the return piece (14) is such that a certain gap is formed between the outer peripheral edge lower end (24) and the air passage (S) through the annular convex portion (15). Is set.
このように、返し片(14)の張り出し長さ及び環状凸部(15)の突出高さは、操作つまみ(2)の凹所(25)との隙間から空気通路(S)への空気の供給が可能となるように、又、操作つまみ(2)の下方への押し込み操作の際に邪魔にならないように、所定の長さ及び高さに設定されている。
これにより、外部の空気は、各図の二点鎖線の矢印に示すように、凹所(25)との隙間から空気通路(S)を通って本体ケース(3)内に取り込まれ、ガスバーナの燃焼用空気や、操作つまみ(2)の下方に設けられているバルブユニット(20)の冷却用空気として利用される。
In this way, the overhang length of the return piece (14) and the protruding height of the annular protrusion (15) are determined by the amount of air flowing from the gap between the operation knob (2) and the recess (25) to the air passage (S). It is set to a predetermined length and height so that it can be supplied and does not get in the way when the operation knob (2) is pushed downward.
As a result, the external air is taken into the main body case (3) through the air passage (S) from the gap with the recess (25) as shown by the two-dot chain arrows in each figure, and the gas burner It is used as combustion air or cooling air for the valve unit (20) provided below the operation knob (2).
又、天板(30)上にこぼした汁や、鍋からの煮こぼれ等を布巾等で手前側に寄せて拭き取る際に、前記汁や煮こぼれ等の液状体が、操作つまみ(2)に向って勢い良く流れてくることがある。このような液状体は、図１の実線の矢印で示すように、延長筒部(13)で堰き止められ、又、延長筒部(13)に当たって上方に跳ね返ったものは返し片(14)の下面に当たるため、それ以上の飛び散りは阻止される。よって、煮こぼれ等の液状体が筒状パッキン(1)を超えて本体ケース(3)内に入り込むことはない。 Also, when spilling juice on the top plate (30) or spilled from the pan with a cloth or the like, wipe the spilled juice or boiled liquid to the operation knob (2). It may flow vigorously. As shown by the solid line arrow in FIG. 1, such a liquid material is dammed up by the extension cylinder part (13), and the one that hits the extension cylinder part (13) and bounces upward is the return piece (14). Since it hits the lower surface, further scattering is prevented. Therefore, a liquid material such as boiled oil does not enter the main body case (3) beyond the cylindrical packing (1).
もし、図３の実線の矢印に示すように、延長筒部(13)に当たった後、返し片(14)の外側へ跳ね返った液状体が、操作つまみ(2)の裏面に付着し、そこから返し片(14)上に滴下されるようなことがあっても、返し片(14)の基端部には、環状凸部(15)が突出していることから、返し片(14)上に滴下された液状体は環状凸部(15)を超えて筒状パッキン(1)内に入り込むことはなく、本体ケース(3)への液状体の浸入を確実に阻止することができる。
以上の効果を確認するため、天板(30)上に２００ミリリットルの水を溢して布巾で操作つまみ(2)側へ向けて拭き取ったところ、図７に示す従来の筒状パッキン(10)を取り付けた構造では、大量の水がコンロ本体(3)内へ浸入していたが、図１に示す実施形態の筒状パッキン(1)を取り付けた構造では、水の浸入が見られなかったことが確認された。
As shown by the solid line arrow in FIG. 3, after hitting the extension cylinder (13), the liquid material that bounces outside the return piece (14) adheres to the back surface of the operation knob (2), and there Even if it drops on the return piece (14), the base end of the return piece (14) protrudes from the annular projection (15). The liquid dropped into the tube does not enter the cylindrical packing (1) beyond the annular protrusion (15), and can reliably prevent the liquid from entering the main body case (3).
In order to confirm the above effect, 200 ml of water overflowed on the top plate (30) and wiped toward the operation knob (2) side with a cloth to find the conventional cylindrical packing (10) shown in FIG. In the structure attached with a large amount of water entered the stove body (3), but in the structure attached with the cylindrical packing (1) of the embodiment shown in FIG. It was confirmed.
さらに、返し片(14)を、図４に示すように、外側へ向って降下するテーパ状に形成しておくと、返し片(14)の上面に滴下された液状体を一層確実に筒状パッキン(1)の外方の天板(30)上へ流し落とすことが出来る。 Furthermore, when the return piece (14) is formed in a tapered shape that descends outward as shown in FIG. 4, the liquid material dropped on the upper surface of the return piece (14) is more reliably cylindrical. It can be poured onto the top plate (30) outside the packing (1).
