Description

本発明は、ガスコンロ等のガスバーナへのガス供給量を調節するガスバルブに関する。   The present invention relates to a gas valve for adjusting a gas supply amount to a gas burner such as a gas stove.

従来、この種のガスバルブは、火力調節レバーの操作と連動してバルブ本体内のニードル弁が上下方向に進退移動してガス流路面積が増減されてガスバーナへのガス供給量が調節されるように構成されている（例えば、特許文献１、特許文献２）。   Conventionally, in this type of gas valve, the needle valve in the valve body moves up and down in conjunction with the operation of the heating power adjustment lever, and the gas flow passage area is increased or decreased to adjust the gas supply amount to the gas burner. (For example, Patent Document 1 and Patent Document 2).

特開２００２−１３７２９号公報JP 2002-13729 A 特開２００６−９８００５号公報JP 2006-98005 A

上記ガスバルブでは、ニードル弁はその軸線方向が縦向きに配置されているためガスバルブの高さが高くなり、ガスコンロの高さも高くなっている。そこで、ガスコンロの高さを低くできるようガスバルブの高さを低くするためニードル弁を横向きに配置させる構成とするのが望ましい。ところが、ニードル弁を縦配置する場合は火力調節レバーが最小火力位置へ急激に操作されてもニードル弁の自重によって最小火力位置で保持され易かったが、ニードル弁を横配置にすると火力調節レバーが最小火力位置へ操作された場合に位置ズレしてニードル弁が最小火力位置で保持されないおそれがある。   In the gas valve, since the needle valve is arranged in the longitudinal direction, the height of the gas valve is high and the height of the gas stove is also high. Therefore, it is desirable to adopt a configuration in which the needle valve is disposed sideways in order to reduce the height of the gas valve so that the height of the gas stove can be lowered. However, when the needle valve is arranged vertically, it was easy to be held at the minimum thermal power position by the self-weight of the needle valve even if the thermal power adjustment lever was suddenly operated to the minimum thermal power position. When operated to the minimum thermal power position, the needle valve may not be held at the minimum thermal power position due to displacement.

本発明は、上記事情に鑑みてなされたものであり、ニードル弁を横配置にするものであって、ニードル弁が最小火力位置に安定して保持されるガスバルブを提供することを課題とする。   This invention is made | formed in view of the said situation, makes a needle valve a horizontal arrangement | positioning, Comprising: It aims at providing the gas valve by which a needle valve is stably hold | maintained in the minimum thermal power position.

本発明に係るガスバルブは、
火力調節レバーの回動操作と連動してバルブ本体内のニードル弁を進退移動させることによりバルブ本体内のガス流路面積が増減されてガスバーナへのガス供給量が調節される構成を備えたガスバルブにおいて、
ニードル弁を横方向に進退移動するように配置し、
火力調節レバーの軸孔をバルブ本体において軸部に回動可能に支持すると共に止めネジを取り付けて抜け止め状態に保持し、且つ火力調節レバーと止めネジとの間に止めネジに一体に組込み可能に構成したバネ部材を配置して火力調節レバーがバネ部材の付勢によりバルブ本体側へ押圧される構成とし、
バルブ本体上面において軸部の根元外周に軸部と所定の間隙を有し分離して***する受け座が形成され、この受け座とバネ部材とにより火力調節レバーの軸孔の周縁部を上下から挟圧する構成としたものである。
上記構成によれば、火力調節レバーは、バネ部材によってバルブ本体側へ押圧されることにより、軸部の軸線方向へ弾性を有する状態で所定の回動荷重をもってバルブ本体に軸支される。従って、ニードル弁を横配置する場合に、使用者が火力調節レバーを最小火力位置へ操作しても火力調節レバーの位置ズレが防止され、火力調節レバーと連動するニードル弁を最小火力位置に安定して保持させることができる。また、上記バネ部材による弾性や回動荷重によって火力調節レバーの良好な操作感も得られる。 The gas valve according to the present invention is
A gas valve having a configuration in which the amount of gas flow in the valve body is increased or decreased by adjusting the amount of gas supplied to the gas burner by moving the needle valve in the valve body forward and backward in conjunction with the turning operation of the thermal power adjustment lever. In
Place the needle valve to move back and forth in the lateral direction,
The shaft hole of the thermal power adjusting lever is held in a state retained by attaching the set screw as well as rotatably supported by the shaft portion in the valve body, and embeddable integrally with the set screw between the thermal power adjusting lever and set screw The spring member configured as described above is arranged so that the heating power adjustment lever is pressed toward the valve body by the bias of the spring member ,
On the upper surface of the valve main body, a receiving seat is formed on the outer periphery of the base of the shaft portion with a predetermined gap from the shaft portion. The receiving seat and the spring member allow the peripheral edge portion of the shaft hole of the heating power adjustment lever to be viewed from above and below. A structure is used for clamping .
According to the above configuration, the thermal power adjusting lever is pivotally supported by the valve body with a predetermined rotational load in a state of being elastic in the axial direction of the shaft portion by being pressed toward the valve body by the spring member. Therefore, when the needle valve is placed horizontally, even if the user operates the thermal power adjustment lever to the minimum thermal power position, displacement of the thermal power adjustment lever is prevented, and the needle valve linked with the thermal power adjustment lever is stabilized at the minimum thermal power position. Can be held. In addition, a good feeling of operation of the heating power adjustment lever can be obtained by the elasticity and rotational load of the spring member.

上記ガスバルブにおいて、バネ部材を止めネジに一体に組込み可能に構成とするので、止めネジの軸部へ取り付けと同時にバネ部材を火力調節レバーと止めネジとの間に配置させることができ、火力調節レバーのバルブ本体への組み付け時の作業性が向上される。
In the above gas valve, the spring member can be integrated into the set screw so that it can be mounted on the shaft of the set screw, and at the same time, the spring member can be placed between the heating power adjustment lever and the set screw. Workability when assembling the lever to the valve body is improved.

上記ガスバルブにおいて、バネ部材は、止めネジと軸部との間に挟持されるリング部と、リング部の外周から外側へ迫り出して火力調節レバーを押圧する複数の脚部とで構成するのが望ましい。
これにより、バネ部材による火力調節レバーの押圧が複数の脚部で分散され、火力調節レバーの操作位置での荷重変化もほとんど生じさせることが無い。従って、例えば、点火操作時に火力調節レバーを強制的に強火力位置に移動させる場合での点火操作力や使用者による火力調節レバーのレバー操作力が安定した荷重となり、火力調節レバーがスムーズに動作される。 In the gas valve, the spring member is composed of a ring portion that is sandwiched between the set screw and the shaft portion, and a plurality of leg portions that press outward from the outer periphery of the ring portion to press the heating power adjustment lever. desirable.
Thereby, the pressing of the heating power adjustment lever by the spring member is dispersed by the plurality of legs, and the load change at the operation position of the heating power adjustment lever hardly occurs. Therefore, for example, when the ignition control lever is forcibly moved to a strong heating position during ignition operation, the ignition operation force or the lever operation force of the user by the user is a stable load, and the heating adjustment lever operates smoothly. Is done.

以上のように、本発明に係るガスバルブによれば、ニードル弁を横配置するものであって、火力調節レバーが最小火力位置へ操作されてもニードル弁が最小火力位置に確実に保持される。従って、正確にガスバーナの最小火力を設定することができる。しかも、バネ部材による弾性や回動荷重によって火力調節レバーの良好な操作感も得られる。   As described above, according to the gas valve of the present invention, the needle valve is disposed horizontally, and the needle valve is reliably held at the minimum heating power position even when the heating power adjustment lever is operated to the minimum heating power position. Therefore, the minimum heating power of the gas burner can be set accurately. In addition, a good feeling of operation of the thermal power adjustment lever can be obtained by the elasticity and rotational load of the spring member.

以下に、本発明の実施形態について添付図面を参照しながら説明する。
図１に示すように、実施形態によるガスバルブ３は、ガスコンロ１内の正面側寄りに組み込まれており、アルミダイカスト製の上本体Ｕ及び下本体Ｓからなるバルブ本体３０の上部に設けられたノズル３０Ａがガスバーナ２のガス入口２０Ｂへ臨むように配設されている。バルブ本体３０内には、バルブ本体３０の下部に開設されたガス導入孔３０Ｂからノズル３０Ａへ繋がるガス流路３００が形成されている。ガス流路３００には、ガスコンロ１の正面パネルに設けられた点消火ボタン１１の点火操作に連動して開き、ガスバーナ２の消火や失火により閉じる電磁安全弁３１と、点消火ボタン１１の点消火操作に連動して開閉するガス元弁３２と、火力調節レバー７の回動位置に応じてガス流路３００の流路面積を増減するニードル弁３３とが、この順序で上流側（ガス導入孔３０Ｂ側）より配設されている。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, the gas valve 3 according to the embodiment is incorporated near the front side in the gas stove 1, and is a nozzle provided on the upper part of the valve body 30 composed of an upper body U and a lower body S made of aluminum die casting. 30A is arranged to face the gas inlet 20B of the gas burner 2. In the valve main body 30, a gas flow path 300 that is connected to the nozzle 30 </ b> A from the gas introduction hole 30 </ b> B opened in the lower portion of the valve main body 30 is formed. In the gas flow path 300, an electromagnetic safety valve 31 that opens in conjunction with the ignition operation of the fire extinguishing button 11 provided on the front panel of the gas stove 1 and closes by extinguishing or misfiring the gas burner 2, and the fire extinguishing operation of the fire extinguishing button 11. The gas source valve 32 that opens and closes in conjunction with the valve and the needle valve 33 that increases or decreases the flow area of the gas flow path 300 according to the rotational position of the heating power adjustment lever 7 are arranged in this order on the upstream side (the gas introduction hole 30B). Side).

また、ガス流路３００の中間部には、ニードル弁３３によって開度調整される弁孔３０１が設けられている。一方、バルブ本体３０内には、その弁孔３０１にまで至る略水平のニードル挿通孔３０２が設けられており、ニードル弁３３は、このニードル挿通孔３０２にその軸線方向に進退自在に配置されている。このようにして、ニードル弁３３は、軸線方向が横向きに配置されている。従って、ガスバルブ３の高さを低くすることができ、このガスバルブ３を組み込むガスコンロ１の高さを低く構成することができる。   Further, a valve hole 301 whose opening degree is adjusted by the needle valve 33 is provided in an intermediate portion of the gas flow path 300. On the other hand, a substantially horizontal needle insertion hole 302 extending to the valve hole 301 is provided in the valve body 30, and the needle valve 33 is disposed in the needle insertion hole 302 so as to be able to advance and retract in the axial direction. Yes. In this way, the needle valve 33 is arranged so that the axial direction is lateral. Accordingly, the height of the gas valve 3 can be reduced, and the height of the gas stove 1 incorporating the gas valve 3 can be reduced.

ニードル弁３３の先端部３３Ａには、その先端部３３Ａが弁孔３０１の周縁（弁座）に当接した最小絞り状態において、ガスバーナ２の最小火力に対応したガス量をノズル３０Ａ側へ導くためのオリフィス孔３３０が設けられている。   The tip 33A of the needle valve 33 guides the gas amount corresponding to the minimum heating power of the gas burner 2 to the nozzle 30A side in the minimum throttle state where the tip 33A is in contact with the peripheral edge (valve seat) of the valve hole 301. Orifice hole 330 is provided.

ニードル弁３３の後部には、細軸の操作ピン３６がニードル弁３３の軸線と交差するように貫通配置されている。この操作ピン３６は、バルブ本体３０の上下に開設されたガイド溝３０３へ挿通されてニードル弁３３の軸線方向への進退移動のみ許容されるようにする。また、操作ピン３６の上端は、バルブ本体３０の上部に水平回動可能な状態で軸支された火力調節レバー４１と係合しており、この火力調節レバー４１の回動操作に応じて操作ピン３６が前後に移動し、ニードル弁３３を進退移動させる連動機構となっている。   A thin-shaft operation pin 36 is disposed through the rear portion of the needle valve 33 so as to intersect the axis of the needle valve 33. The operation pin 36 is inserted into a guide groove 303 provided at the top and bottom of the valve main body 30 so that only the forward and backward movement of the needle valve 33 in the axial direction is allowed. Further, the upper end of the operation pin 36 is engaged with a thermal power adjustment lever 41 that is pivotally supported on the upper portion of the valve body 30 so as to be horizontally rotatable, and is operated according to the rotational operation of the thermal power adjustment lever 41. The pin 36 moves back and forth, and is an interlocking mechanism that moves the needle valve 33 forward and backward.

具体的には、図２に示すように、バルブ本体３０の上部に軸支された長尺板状の火力調節レバー４１の中間部には、操作ピン３６と略同幅のスリット４１１が開設されており、このスリット４１１に操作ピン３６の上端が挿通されている。また、スリット４１１は、火力調節レバー４１の左前方から右後方へ向かって円弧状に形成されており、火力調節レバー４１が右へ回動操作されるとスリット４１１の前縁部Ｅ１が操作ピン３６を手前側へ移動させ、左へ回動操作されるとスリット４１１の後縁部Ｅ２が操作ピン３６を奥側へ移動させる。   Specifically, as shown in FIG. 2, a slit 411 having a width substantially the same as that of the operation pin 36 is formed in the middle portion of the long plate-like thermal power adjusting lever 41 that is pivotally supported on the upper portion of the valve body 30. The upper end of the operation pin 36 is inserted into the slit 411. The slit 411 is formed in an arc shape from the left front side to the right rear side of the thermal power adjustment lever 41. When the thermal power adjustment lever 41 is rotated to the right, the front edge E1 of the slit 411 is operated as an operation pin. When 36 is moved to the front side and rotated to the left, the rear edge E2 of the slit 411 moves the operation pin 36 to the back side.

火力調節レバー４１は、図３に示すように、その一端に形成された軸孔４１０をバルブ本体３０の上部に形成された円柱状の軸部４２に外嵌させた状態で支持されており、その軸部４２を中心に回動するように構成されている。また、軸部４２の上部には、軸孔４１０より大径のフランジ４３Ａを有する止めネジ４３が螺合接続されており、火力調節レバー４１を抜け止め状態で保持している。なお、このフランジ４３Ａは、止めネジ４３と別部材で構成されてもよい。   As shown in FIG. 3, the thermal power adjustment lever 41 is supported in a state in which a shaft hole 410 formed at one end thereof is externally fitted to a columnar shaft portion 42 formed at the top of the valve body 30. The shaft portion 42 is configured to rotate around. Further, a set screw 43 having a flange 43A having a diameter larger than that of the shaft hole 410 is screwed to the upper portion of the shaft portion 42, and the fire power adjusting lever 41 is held in a state of being prevented from coming off. The flange 43A may be formed of a member separate from the set screw 43.

フランジ４３Ａと火力調節レバー４１との間には、火力調節レバー４１を下方へ押圧付勢する板バネ（バネ部材）４４が設けられている。この板バネ４４は、図４に示すように、軸部４２と略同外径のリング部４４Ａと、リング部４４Ａの外周から外側へ放射状に延びる複数（ここでは、３本）の脚部４４Ｂとで構成されている。リング部４４Ａは軸部４２とフランジ４３Ａによって挟持固定されている。脚部４４Ｂは、軸部４２の上面外周から外側下方に迫り出してその先端下面が火力調節レバー４１の軸孔４１０の周縁上面に当接して下方へ押圧している。   A leaf spring (spring member) 44 is provided between the flange 43A and the thermal power adjustment lever 41 to press and bias the thermal power adjustment lever 41 downward. As shown in FIG. 4, the leaf spring 44 includes a ring portion 44A having substantially the same outer diameter as the shaft portion 42, and a plurality of (here, three) leg portions 44B extending radially outward from the outer periphery of the ring portion 44A. It consists of and. The ring portion 44A is clamped and fixed by the shaft portion 42 and the flange 43A. The leg portion 44 </ b> B protrudes outward and downward from the outer periphery of the upper surface of the shaft portion 42, and the lower end surface of the leg portion 44 </ b> abuts against the upper surface of the peripheral edge of the shaft hole 410 of the thermal power adjustment lever 41 and presses downward.

板バネ４４は、軸挿通孔４４０が星型に切り抜かれて止めネジ４３のネジ軸４３０の根元部に対して容易に抜け落ちないように外嵌される構成となっている。そして、火力調節レバー４１をバルブ本体３０へ組み付ける際には、先に板バネ４４を止めネジ４３のネジ軸４３０に嵌めて一体に組込み、その後、火力調節レバー４１の軸孔４１０を軸部４２へ係合させた状態で、上述した止めネジ４３を軸部４２の上部へ螺合接続すれば、板バネ４４が止めネジ４３と火力調節レバー４１との間に配置される。これにより、止めネジ４３の軸部４２へ取り付けと同時に板バネ４４を火力調節レバー４１と止めネジ４３との間に配置させることができ、火力調節レバー４１のバルブ本体３０への組み付け時の作業性が向上される。   The plate spring 44 is configured to be externally fitted so that the shaft insertion hole 440 is cut out in a star shape and does not easily fall off from the root portion of the screw shaft 430 of the set screw 43. When the thermal power adjustment lever 41 is assembled to the valve body 30, the plate spring 44 is first fitted into the screw shaft 430 of the set screw 43 and integrated together, and then the shaft hole 410 of the thermal power adjustment lever 41 is inserted into the shaft portion 42. When the set screw 43 described above is screwed and connected to the upper portion of the shaft portion 42 in the engaged state, the leaf spring 44 is disposed between the set screw 43 and the heating power adjustment lever 41. Accordingly, the leaf spring 44 can be disposed between the heating power adjustment lever 41 and the set screw 43 simultaneously with the attachment of the set screw 43 to the shaft portion 42, and the work when the heating power adjustment lever 41 is assembled to the valve body 30. Is improved.

また、バルブ本体３０上面の軸部４２の根元外周には、環状に***する受け座４５が形成されており、火力調節レバー４１の軸孔４１０の周縁下面は、この受け座４５の上面に当接されている。これにより、火力調節レバー４１は、板バネ４４と受け座４５によって軸孔４１０の周縁部が上下から挟圧されており、上下へ弾性を有する状態で且つ適度な回動荷重をもって、バルブ本体３０の上面に軸支される。従って、ニードル弁３３を横配置する場合に、使用者が火力調節レバー４１を最小火力位置（最も左の位置）へ操作しても火力調節レバー４１の位置ズレが防止される。よって、火力調節レバー４１と連動するニードル弁３３の先端部３３Ａを弁座に当接した最小絞りの状態で安定して保持させることができ、ガスバーナ２の最小火力を正確に設定することができる。また、板バネ４４による弾性や回動荷重によって火力調節レバー４１の良好な操作感も得られる。   A receiving seat 45 bulging in an annular shape is formed on the base outer periphery of the shaft portion 42 on the upper surface of the valve body 30, and the lower peripheral edge of the shaft hole 410 of the heating power adjusting lever 41 is in contact with the upper surface of the receiving seat 45. It is touched. As a result, the thermal power adjusting lever 41 has the peripheral portion of the shaft hole 410 sandwiched from above and below by the leaf spring 44 and the receiving seat 45, and is elastic in the up and down direction and has an appropriate rotational load. It is pivotally supported on the upper surface. Therefore, when the needle valve 33 is disposed horizontally, even if the user operates the thermal power adjustment lever 41 to the minimum thermal power position (the leftmost position), displacement of the thermal power adjustment lever 41 is prevented. Therefore, the distal end portion 33A of the needle valve 33 interlocked with the heating power adjustment lever 41 can be stably held in the minimum throttle state in contact with the valve seat, and the minimum heating power of the gas burner 2 can be set accurately. . In addition, a good feeling of operation of the heating power adjustment lever 41 can be obtained by the elasticity and rotational load of the leaf spring 44.

さらに、板バネ４４による火力調節レバー４１の押圧が複数の脚部４４Ｂで分散され、火力調節レバー４１の操作位置での荷重変化もほとんど生じさせることが無い。従って、点火操作時に火力調節レバー４１を強制的に強火力位置に移動させる場合での点火操作力や使用者による火力調節レバー４１のレバー操作力が安定した荷重となり、火力調節レバー４１がスムーズに動作される。   Further, the pressing of the heating power adjustment lever 41 by the leaf spring 44 is dispersed by the plurality of legs 44B, and the load change at the operation position of the heating power adjustment lever 41 hardly occurs. Accordingly, the ignition operation force when the thermal power adjustment lever 41 is forcibly moved to the strong thermal power position during the ignition operation and the lever operation force of the thermal power adjustment lever 41 by the user become a stable load, and the thermal power adjustment lever 41 smoothly moves. Be operated.

Further, the ring portion 46A may be clamped and fixed by the shaft portion 42 and the flange 43A of the set screw 43, and the lower end surface of the umbrella portion 46B may be in contact with and press against the peripheral upper surface of the shaft hole 410 of the thermal power adjustment lever 41. Further, like the leaf spring 47 shown in FIG. 6, it is formed in a wave-like ring shape, and the upper surface of the convex portion 47A of this leaf spring 47 is pressed against the lower surface of the flange 43A of the set screw 43, and the concave portion 47B It may be configured such that the lower surface presses and contacts the upper surface of the thermal power adjustment lever 41.

The base plate 48A is sandwiched in the gap between the upper surface of the heating power adjustment lever 41 and the flange 43A of the set screw 43, and the lower surface of the tip of the leg portion 48B is an intermediate portion of the heating power adjustment lever 41. It may be pressed against the upper surface.

また、上記実施形態では、バルブ本体３に設けた軸部４２は中心にネジ穴を備えた円柱状として、この円柱状の軸部４２の高さの中に火力調節レバー４１と板バネ４４（４６，４７，４８）を配置させたが、止めネジ４３を段部を有する段付きネジ形状として、その段部を軸部４２と見て段部の高さの中に火力調節レバー４１と板バネ４４（４６，４７，４８）を配置させても良い。この場合、段付きネジ形状の止めネジ４３を取り付けるバルブ本体３の箇所は、ネジ穴を備えた平坦な部分とすることができる。   Moreover, in the said embodiment, the axial part 42 provided in the valve | bulb main body 3 is made into the column shape provided with the screw hole in the center, and the thermal-power adjustment lever 41 and the leaf | plate spring 44 ( 46, 47, 48), but the set screw 43 has a stepped screw shape having a stepped portion, and the stepped portion is viewed as the shaft portion 42, and the heating power adjusting lever 41 and the plate are within the height of the stepped portion.
