Description

本発明はガスコンロに関する。 The present invention relates to gas stoves.

ガスコンロは、コンロバーナにガスを供給する燃料供給装置を備える。例えば特許文献１に記載の回転操作部は、押圧操作可能且つ回転操作可能に構成されている。回転操作部は、点火時には押圧操作によりガスコンロの前面パネルから突出する突出状態となり、消火時には押圧操作により突出状態よりも後方に退避する退避状態になる。そして突出状態のとき、回転操作部は回転操作によって火力の調整を行う。前面パネルには回転操作部が挿入される貫通孔が形成されており、貫通孔にはリング部材が配置される。リング部材は、貫通孔の内周壁と回転操作部との間に構成される環状空間を埋め、ガスコンロの美観の低下を抑える。 A gas stove includes a fuel supply that supplies gas to the stove burner. For example, the rotary operation section described in Patent Document 1 is configured to be capable of being pressed and rotated. When the rotary operation part is ignited, the pressing operation causes the rotating operation part to be in a protruded state in which it protrudes from the front panel of the gas stove. In the projecting state, the rotary operation unit adjusts the heating power by rotating. The front panel is formed with a through hole into which the rotary operation part is inserted, and a ring member is arranged in the through hole. The ring member fills the annular space formed between the inner peripheral wall of the through hole and the rotary operation part, thereby suppressing deterioration of the appearance of the gas stove.

しかしながら、特許文献１のリング部材は、回転操作部とは別体の部品であるので、部品点数が増える。また、前面パネルは、リング部材を配置するための部位を設ける必要があるので、加工のための工数が増える。このため、ガスコンロの製造コストがかかるという問題があった。 However, the ring member of Patent Literature 1 is a part separate from the rotary operation portion, so the number of parts increases. Moreover, since the front panel needs to be provided with a portion for arranging the ring member, the number of man-hours for processing increases. Therefore, there is a problem that the manufacturing cost of the gas stove is high.

本発明の目的は、製造コストを低減しつつ美観を損ねないガスコンロを提供することである。 SUMMARY OF THE INVENTION An object of the present invention is to provide a gas stove which does not impair the appearance while reducing manufacturing costs.

A portion is provided, and the blind portion protrudes forward from the front end portion of the main body portion, and the tip portion is disposed in the stepped portion.

請求項３に係る発明のガスコンロは、請求項２に記載の発明の構成に加え、
前記目隠部は、帯状且つ環状の前面を有し、前記目隠部の前記先端部が前記段部内に配置される場合に、前記目隠部の前面は、前記段部の後面に当接又は近接した状態であり、前記化粧パネルの後面における前記段部の内径は、前記目隠部の前記先端部の外径よりも大きいことを特徴とする。 The gas stove of the invention according to claim 3, in addition to the configuration of the invention according to claim 2,
The blind portion has a band-shaped and annular front surface, and when the front end portion of the blind portion is disposed in the stepped portion, the front surface of the blind portion contacts the rear surface of the stepped portion. Alternatively, they are close to each other, and the inner diameter of the step portion on the rear surface of the decorative panel is larger than the outer diameter of the tip portion of the blind portion.

請求項４に係る発明のガスコンロは、請求項１から３のいずれかに記載の発明の構成に加え、前記操作つまみが前記待機位置にあるときに、前記操作つまみの外周面において、前記接続部に対向する対向位置における前記操作つまみの外径は、前記操作つまみの外周面における前端位置よりも外径が大きく、前記操作つまみの外周面は、前記前端位置から、前記対向位置よりも後側の位置にかけて、外径が大きくなるテーパ状を呈することを特徴とする。 The gas stove of the invention according to claim 4 , in addition to the configuration of the invention according to any one of claims 1 to 3 , is characterized in that when the operation knob is in the standby position, the connection portion The outer diameter of the operation knob at the facing position facing the . It is characterized by exhibiting a tapered shape in which the outer diameter increases toward the position of .

請求項１に係る発明のガスコンロによれば、操作つまみは、少なくともガスの供給時にはパネル装置の前面に対して突出し、ガスの供給量が調整される場合には回動操作される。故に、操作つまみの外周面と、化粧パネルの開口部の内周面との間には、円滑な操作のための間隙が設けられる。目隠部は、操作つまみの外径よりも大きく、開口部の内径よりも小さい。よって、ガスコンロを前方から見たとき、操作つまみと開口部の間隙内は、目隠部に遮られて奥が見えにくくなるので、ガスコンロの美観を損ねない。また、目隠部は鍔付筒部と一体に設けられるので、別体に設けた場合と比べて部品点数を減らすことができ、且つ目隠部を鍔付筒部と別体で設けた場合に化粧パネルにおいて必要となる目隠部の取付部位の加工に要する工数を削減できるので、ガスコンロの製造コストを低減することができる。
目隠部は、接続部において最も内径が小さい。故に、操作つまみと開口部の間隙内は、接続部よりも後側が見えにくく、ガスコンロの美観を損ねない。また、目隠部の内周面は、接続部において操作つまみの表面に最も近接し、曲面部とテーパ部において接続部から離れるほど操作つまみの表面から遠ざかる。操作部の操作において目隠部が操作つまみに接触しても、接続部が操作つまみに接触し、曲面部とテーパ部を含む他の部分が接触することがないので、操作つまみにかかる接触抵抗は小さい。故に、点火操作を行うとき、操作つまみは前後方向に円滑に変位することができる。 According to the gas stove of the first aspect of the invention, the operation knob protrudes from the front surface of the panel device at least when gas is supplied, and is rotated when the amount of gas supply is adjusted. Therefore, a gap for smooth operation is provided between the outer peripheral surface of the operation knob and the inner peripheral surface of the opening of the decorative panel. The blind portion is larger than the outer diameter of the operation knob and smaller than the inner diameter of the opening. Therefore, when the gas stove is viewed from the front, the inside of the gap between the operation knob and the opening is blocked by the blindfold, making it difficult to see the back, so that the appearance of the gas stove is not spoiled. In addition, since the blindfold part is provided integrally with the flanged tubular part, the number of parts can be reduced compared to the case where the blindfolded part is provided separately, and the blindfold part is provided separately from the flanged tubular part. Moreover, since the number of man-hours required for processing the mounting portion of the blind portion, which is required in the decorative panel, can be reduced, the manufacturing cost of the gas stove can be reduced.
The blind portion has the smallest inner diameter in the connecting portion. Therefore, in the gap between the operation knob and the opening, it is difficult to see the rear side of the connecting portion, and the appearance of the gas stove is not spoiled. In addition, the inner peripheral surface of the blind portion is closest to the surface of the operation knob at the connection portion, and becomes farther from the surface of the operation knob at the curved surface portion and the tapered portion as the distance from the connection portion increases. Even if the blind part touches the operation knob during operation of the operation part, the connection part contacts the operation knob and other parts including the curved surface part and the tapered part do not come into contact, so the contact resistance applied to the operation knob is reduced. is small. Therefore, when the ignition operation is performed, the operation knob can be smoothly displaced in the front-rear direction.

請求項２に係る発明のガスコンロによれば、請求項１に記載の発明の効果に加え、操作つまみの回動操作に応じて本体部が回動すると、目隠部は、操作つまみの外周面に沿って回動する。目隠部は、先端部が化粧パネルの段部内に配置され、回動時に段部によって位置決められるので、鍔付筒部の回動が安定する。操作つまみが回動する時も、目隠部の内周面と操作つまみの外周面との間に間隙が確保されるので、間隙内の奥が目隠部によって見えにくく、ガスコンロは美観を損ねない。また、間隙の確保により、目隠部は、操作つまみの回動操作に対し接触抵抗を与えにくいので、操作部の操作性を確保できる。 According to the gas stove of the invention according to claim 2, in addition to the effect of the invention according to claim 1, when the main body rotates according to the rotation operation of the operation knob, the blind part is formed on the outer peripheral surface of the operation knob. Rotate along. The tip portion of the blindfold portion is disposed within the stepped portion of the decorative panel, and is positioned by the stepped portion during rotation, so that rotation of the flanged tubular portion is stabilized. Even when the operation knob rotates, a gap is secured between the inner peripheral surface of the blindfold part and the outer peripheral surface of the operation knob, so that it is difficult to see the inner part of the gap due to the blindfold part, which spoils the appearance of the gas stove. do not have. In addition, by ensuring the gap, the blind portion does not easily give contact resistance to the turning operation of the operation knob, so that the operability of the operation portion can be ensured.

請求項３に係る発明のガスコンロによれば、請求項２に記載の発明の効果に加え、化粧パネルの後面における段部の内径は、目隠部の先端部の外径よりも大きい。故に、目隠部は、段部の内径と目隠部の先端部の外径との径差の範囲内で、開口部の中心軸に対する軸ずれが許容される。この構成により、開口部の中心軸に対する操作つまみの軸ずれに合わせて目隠部も軸ずれすることができるので、軸ずれによって間隙が偏り大きな隙間が生じた場合でも、間隙内の奥が目隠部によって見えにくく、ガスコンロは美観を損ねない。また、目隠部の前面が段部の後面に当接又は近接した状態であるので、振動等による目隠部の軸ずれを抑制し、目隠しの効果を維持することができる。 According to the gas stove of the invention according to claim 3, in addition to the effect of the invention according to claim 2, the inner diameter of the stepped portion on the rear surface of the decorative panel is larger than the outer diameter of the tip portion of the blind portion. Therefore, the blind portion is allowed to be misaligned with respect to the central axis of the opening within the range of the diameter difference between the inner diameter of the stepped portion and the outer diameter of the tip portion of the blind portion. With this configuration, the blind portion can also be displaced along with the misalignment of the operation knob with respect to the central axis of the opening. The hidden part makes it difficult to see, and the gas stove does not spoil the aesthetic appearance. Further, since the front surface of the blind portion is in contact with or in close proximity to the rear surface of the stepped portion, it is possible to suppress axial deviation of the blind portion due to vibration or the like and maintain the blind effect.

請求項４に係る発明のガスコンロによれば、請求項１から３のいずれかに記載の発明の効果に加え、操作つまみが待機位置にあるとき、操作つまみと開口部の間隙は、接続部に対向する対向位置において最も小さい。更に、操作つまみの外周面は、前端位置から対向位置よりも後側の位置にかけて外径が大きくなるテーパ状を呈する。このため、前方から操作つまみと開口部の間隙内を覗いた場合に、対向位置の前側には目隠部が見え、対向位置の後側には操作つまみの外周面が見え、他の部位が見えにくいので、ガスコンロは美観を損ねない。 According to the gas stove of the invention according to claim 4 , in addition to the effect of the invention according to any one of claims 1 to 3 , when the operation knob is in the standby position, the gap between the operation knob and the opening is at the connection part Smallest at opposite facing positions. Furthermore, the outer peripheral surface of the operation knob has a tapered shape in which the outer diameter increases from the front end position to the position on the rear side of the facing position. Therefore, when looking into the gap between the operation knob and the opening from the front, the blind part can be seen on the front side of the facing position, the outer peripheral surface of the operation knob can be seen on the rear side of the facing position, and other parts can be seen. Since it is hard to see, the gas stove does not spoil the aesthetic appearance.

The safety valve 48 is an electromagnetically operated valve that is elastically biased to a closed state that closes the first gas passage 46 . The main valve 39 is a valve that opens and closes the first gas passage 46 according to the pushing operation of the operation knob 14 . Since both the main valve 39 and the safety valve 48 are well known, detailed description of their operation will be omitted.

流量調節部３１はプッシュ・プッシュ機構２４とガス流路部２２の上部に設けられる。流量調節部３１の内部には第二ガス通路１９が形成される。第二ガス通路１９は、ガス流路部２２から供給されるガスを流通し、上部に開口する流出口３２に接続されるガス供給管１８を介して左バーナ５に供給する。流量調節部３１の前端部には第二ガス通路１９に連通する穴部３０が形成され、ニードル弁２８が挿入される。ニードル弁２８は、前端部側が穴部３０から外部に露出され、後端部側が第二ガス通路１９内にて前後方向に移動可能に配置される。ニードル弁２８の前端部には、上下方向に延びるピン２９が設けられる。ピン２９の下端部は、火力調節カム２６のカム溝２７（後述）に係合する。 The flow control section 31 is provided above the push-push mechanism 24 and the gas flow path section 22 . A second gas passage 19 is formed inside the flow control portion 31 . The second gas passage 19 circulates the gas supplied from the gas passage portion 22 and supplies the gas to the left burner 5 via the gas supply pipe 18 connected to the outlet 32 opening at the top. A hole portion 30 communicating with the second gas passage 19 is formed in the front end portion of the flow control portion 31, and the needle valve 28 is inserted therein. The needle valve 28 is arranged so that the front end side is exposed to the outside through the hole 30 and the rear end side is movable in the front-rear direction inside the second gas passage 19 . A vertically extending pin 29 is provided at the front end of the needle valve 28 . A lower end of the pin 29 engages with a cam groove 27 (described later) of the thermal power adjustment cam 26 .

火力調節カム２６は略半円筒状に形成され、プッシュ・プッシュ機構２４の前端側上部を覆うようにして、軸線ＡＸの回りを回転可能に設けられる。火力調節カム２６は、前後方向への移動が規制される。火力調節カム２６の外周部には、カム溝２７が設けられる。カム溝２７は、軸線ＡＸを中心とする螺旋状に形成される。カム溝２７にはニードル弁２８に設けられたピン２９の下端部が係合する。火力調節カム２６が回転すると、カム溝２７がピン２９を案内し、ニードル弁２８を前後方向に移動する。 The heating power control cam 26 is formed in a substantially semi-cylindrical shape and is provided rotatably around the axis AX so as to cover the front end side upper portion of the push-push mechanism 24 . The heating power control cam 26 is restricted from moving in the front-rear direction. A cam groove 27 is provided on the outer peripheral portion of the heating power control cam 26 . The cam groove 27 is spirally formed around the axis AX. A lower end of a pin 29 provided on a needle valve 28 is engaged with the cam groove 27 . When the heat control cam 26 rotates, the cam groove 27 guides the pin 29 and moves the needle valve 28 in the front-rear direction.

火力調節カム２６は、前方に延びる延伸部（図示略）を備え、延伸部の前端部分に内向きに突出する歯部３５を有する。歯部３５は操作つまみ１４が操作位置にあるときに連結部材２５の歯部３８（後述）に噛合し、連結部材２５を介して火力調節カム２６を操作つまみ１４と共に軸線ＡＸを中心に回転する。火力調節カム２６の延伸部の外周面には、ＬＥＤ操作部材３６が固定される。ＬＥＤ操作部材３６は、前方に延びる係合片３７を有する。ＬＥＤ操作部材３６は鍔付筒部７０（後述）に係合し、鍔付筒部７０を火力調節カム２６と共に軸線ＡＸを中心に回転する。 The power control cam 26 includes a forwardly extending extension (not shown) having inwardly projecting teeth 35 at the front end portion of the extension. The toothed portion 35 meshes with a toothed portion 38 (described later) of the connecting member 25 when the operating knob 14 is in the operating position, and rotates the thermal power control cam 26 together with the operating knob 14 around the axis AX via the connecting member 25. . An LED operation member 36 is fixed to the outer peripheral surface of the extended portion of the heating power control cam 26 . The LED operation member 36 has an engaging piece 37 extending forward. The LED operation member 36 engages with a flanged tubular portion 70 (described later), and rotates the flanged tubular portion 70 together with the thermal power adjustment cam 26 about the axis AX.

操作部２１の連結部材２５は、プッシュ・プッシュ機構２４のスライダ４０から前方に延び、軸線ＡＸを軸とする軸体３４に係合する。連結部材２５は軸体３４の前端部にて操作つまみ１４を一体に固定し、操作つまみ１４と共に軸線ＡＸを中心に回転可能に設けられる。連結部材２５は、後端部外周面に、火力調節カム２６の歯部３５に噛合する歯部３８を有する。操作つまみ１４が操作位置にあるとき、連結部材２５の歯部３８は火力調節カム２６の歯部３５と噛合し、操作つまみ１４と火力調節カム２６を連結する。操作つまみ１４が操作位置にない場合には、火力調節カム２６の歯部３５は連結部材２５の歯部３８の前方に位置して噛合せず、操作つまみ１４と火力調節カム２６の連結状態を解除する。 The connecting member 25 of the operating portion 21 extends forward from the slider 40 of the push-push mechanism 24 and engages with the shaft 34 having the axis AX as its axis. The connecting member 25 integrally fixes the operation knob 14 at the front end portion of the shaft 34 and is rotatable together with the operation knob 14 about the axis AX. The connecting member 25 has a toothed portion 38 that meshes with the toothed portion 35 of the thermal power control cam 26 on the outer peripheral surface of the rear end portion. When the operating knob 14 is at the operating position, the toothed portion 38 of the connecting member 25 meshes with the toothed portion 35 of the heating power adjusting cam 26 to connect the operating knob 14 and the heating power adjusting cam 26 . When the operating knob 14 is not in the operating position, the teeth 35 of the heating power adjusting cam 26 are positioned in front of the teeth 38 of the connecting member 25 and do not mesh with each other. unlock.

次に、操作つまみ１４の回動操作による点火及び消火と火力の調節について説明する。左バーナ５の消火時、操作つまみ１４は、待機位置にある。ユーザが操作つまみ１４を押し込み、操作つまみ１４が押込位置に移動する過程で、安全弁４８とメイン弁３９が開放され、イグナイタ（図示略）によって左バーナ５が点火される。ユーザが操作つまみ１４から手を離すと、操作つまみ１４はバネの付勢により操作位置に移動する。安全弁４８とメイン弁３９は開放状態に維持される。連結部材２５によって、操作つまみ１４と火力調節カム２６が連結される。 Next, ignition and extinguishing by rotating the operation knob 14 and adjustment of heat power will be described. When the left burner 5 is extinguished, the operating knob 14 is at the standby position. When the user pushes the operation knob 14 and moves the operation knob 14 to the pushed position, the safety valve 48 and the main valve 39 are opened, and the left burner 5 is ignited by an igniter (not shown). When the user releases the operating knob 14, the operating knob 14 moves to the operating position due to the force of the spring. The safety valve 48 and the main valve 39 are kept open. A connecting member 25 connects the operation knob 14 and the heating power control cam 26 .

操作つまみ１４が操作位置にある状態で操作つまみ１４が回動操作されると、火力調節カム２６は操作つまみ１４と共に軸線ＡＸの回りを回転する。火力調節カム２６が回転すると、ニードル弁２８のピン２９がカム溝２７に案内されて、前後方向に移動する。これにより、ニードル弁２８が前後方向に移動するので、ニードル弁２８の位置に応じて、第二ガス通路１９を流通するガスの流量が調節され、左バーナ５の火力が変更される。 When the operating knob 14 is turned while it is at the operating position, the thermal power adjusting cam 26 rotates together with the operating knob 14 around the axis AX. When the heating power control cam 26 rotates, the pin 29 of the needle valve 28 is guided by the cam groove 27 and moves forward and backward. As a result, the needle valve 28 moves forward and backward, so the flow rate of the gas flowing through the second gas passage 19 is adjusted according to the position of the needle valve 28, and the heating power of the left burner 5 is changed.

ユーザが操作つまみ１４を押し込み、操作つまみ１４が押込位置に移動する過程で、安全弁４８とメイン弁３９が閉鎖される。左バーナ５は消火する。ユーザが操作つまみ１４から手を離すと、操作つまみ１４はバネの付勢により待機位置に移動する。安全弁４８とメイン弁３９は閉鎖状態に維持される。 The user pushes the operation knob 14 and the safety valve 48 and the main valve 39 are closed in the process of moving the operation knob 14 to the pushed position. The left burner 5 is extinguished. When the user releases the operation knob 14, the operation knob 14 moves to the standby position due to the force of the spring. The safety valve 48 and the main valve 39 are kept closed.

このように、燃料供給装置２０は、操作つまみ１４の回動操作に伴い、火力調節カム２６がニードル弁２８を移動することによって、流量調節部３１の第二ガス通路１９を流通するガスの流量を無段階に調節する。即ち、操作つまみ１４の回転量に応じて、左バーナ５の火力がリニアに変化する。右バーナ４、奥バーナ６に夫々対応する操作つまみ１１、１３についても同様である。ガスコンロ１は、操作つまみ１１、１３、１４の夫々の回転量に応じた火力表示を行うため、前面に設けるパネル装置９Ａ、９Ｂに火力表示機能を備える。 As described above, the fuel supply device 20 adjusts the flow rate of the gas flowing through the second gas passage 19 of the flow rate adjusting portion 31 by moving the heating power adjusting cam 26 through the needle valve 28 as the operation knob 14 is rotated. steplessly adjusted. That is, the heating power of the left burner 5 linearly changes according to the amount of rotation of the operation knob 14 . The same applies to the operation knobs 11 and 13 corresponding to the right burner 4 and the rear burner 6, respectively. In the gas stove 1, panel devices 9A and 9B provided on the front surface have a heating power display function in order to display the heating power according to the amount of rotation of each of the operation knobs 11, 13 and 14. FIG.

図１に示すように、ガスコンロ１は、グリル扉８の右側の領域に、右バーナ４とグリル装置の火力表示を行うパネル装置９Ａを備え、グリル扉８の左側の領域に、左バーナ５と奥バーナ６の火力表示を行うパネル装置９Ｂを備える。 As shown in FIG. 1, the gas stove 1 includes a right burner 4 and a panel device 9A for displaying the heating power of the grill device on the right side of the grill door 8, and a left burner 5 and a panel device 9A on the left side of the grill door 8. A panel device 9B for displaying the heat power of the back burner 6 is provided.

なお、グリル装置の燃料供給装置は、操作つまみ１２の回転位置に応じてオン・オフが切り替わる複数のスイッチ（図示略）を備える。グリル装置の流量調節部は、複数のスイッチのオン・オフの状態に応じて複数の電磁弁の開閉状態を切り替えることによって、グリルバーナの火力調節を行う。従って、グリル装置の火力表示は、複数のスイッチのオン・オフの状態に合わせ、パネル装置９Ａに設けたＬＥＤの点灯・消灯の状態を段階的に切り替えることによって行われる。 It should be noted that the fuel supply device of the grill device has a plurality of switches (not shown) that are switched between on and off according to the rotational position of the operation knob 12 . The flow control unit of the grilling device adjusts the heating power of the grill burner by switching the open/closed states of the plurality of electromagnetic valves according to the ON/OFF states of the plurality of switches. Therefore, the heating power display of the grill device is performed by switching the ON/OFF state of the LED provided on the panel device 9A in stages in accordance with the ON/OFF states of the plurality of switches.

これに対し、パネル装置９Ａにおける右バーナ４の火力表示と、パネル装置９Ｂにおける左バーナ５と奥バーナ６の火力表示を行う上で、燃料供給装置２０は、操作つまみ１１、１３、１４の回転量を検出するエンコーダを搭載しない。よって、パネル装置９Ａ、９Ｂは、操作つまみ１１、１３、１４の回転位置に応じてＬＥＤの点灯・消灯の状態を切り替える制御は行わない。本実施形態では、パネル装置９Ａ、９Ｂは、操作つまみ１１、１３、１４の回転位置に対応する位置のＬＥＤ光を透過し、他の位置のＬＥＤ光を遮蔽することによって火力表示を行う。 On the other hand, in displaying the heating power of the right burner 4 on the panel device 9A and the heating power of the left burner 5 and the back burner 6 on the panel device 9B, the fuel supply device 20 is operated by rotating the operation knobs 11, 13, and 14. It does not have an encoder that detects the amount. Therefore, the panel devices 9A and 9B do not perform control for switching the ON/OFF state of the LEDs according to the rotational positions of the operation knobs 11, 13, and 14. FIG. In this embodiment, the panel devices 9A and 9B transmit the LED light at positions corresponding to the rotational positions of the operation knobs 11, 13, and 14, and shield the LED light at other positions to display the heat power.

図２～図８を参照し、パネル装置９Ｂについて説明する。なお、パネル装置９Ａにおける右バーナ４の火力表示に係る部分の構成は、パネル装置９Ｂにおける左バーナ５、奥バーナ６の火力表示に係る部分の構成と同じである。よって、パネル装置９Ａの構成は、パネル装置９Ｂの構成に準ずるものとして、説明を省略する。 The panel device 9B will be described with reference to FIGS. 2 to 8. FIG. The configuration of the portion relating to the heating power display of the right burner 4 in the panel device 9A is the same as the configuration of the portion relating to the heating power display of the left burner 5 and the rear burner 6 in the panel device 9B. Therefore, the configuration of the panel device 9A is assumed to conform to the configuration of the panel device 9B, and the description thereof is omitted.

パネル装置９Ｂは、パネル本体部５０、表示基板６０、化粧パネル８０、鍔付筒部７０を備える。パネル本体部５０は、筐体２の前端部に組み付けられる。図４に示すように、パネル本体部５０の下側部分５１は箱型に形成され、操作パネル（図示略）が収容される。パネル本体部５０の上側部分５２は、下側部分５１から上方へ向けて板状に突出する。上側部分５２には、前後方向に貫通する２つの貫通穴５３が左右方向に並んで形成される。貫通穴５３の内径Ｄ１は、操作つまみ１４の外径Ｄ２より大きい。操作つまみ１１～１３も同様である。なお、操作つまみ１４の外周面は、少なくとも一部が、僅かながら、前側よりも後側の外径が大きいテーパ状を呈しており（図８参照）、外径Ｄ２は最大外径をいう。左バーナ５用の燃料供給装置２０と奥バーナ６用の燃料供給装置２０は、左右に並べた状態で、取付金具３３を用い、パネル本体部５０の上側部分５２の裏面に螺子で固定される。２つの燃料供給装置２０の連結部材２５と操作つまみ１３、１４は夫々、２つの貫通穴５３内に配置される。 The panel device 9B includes a panel main body 50, a display substrate 60, a decorative panel 80, and a flanged tubular portion . The panel main body portion 50 is attached to the front end portion of the housing 2 . As shown in FIG. 4, the lower portion 51 of the panel main body 50 is formed in a box shape and accommodates an operation panel (not shown). An upper portion 52 of the panel main body portion 50 protrudes upward from the lower portion 51 in a plate shape. The upper portion 52 is formed with two through holes 53 that penetrate in the front-rear direction and are arranged side by side in the left-right direction. An inner diameter D1 of the through-hole 53 is larger than an outer diameter D2 of the operation knob 14 . The operation knobs 11-13 are the same. At least a portion of the outer peripheral surface of the operation knob 14 is tapered such that the rear side has a larger outer diameter than the front side (see FIG. 8), and the outer diameter D2 is the maximum outer diameter. The fuel supply device 20 for the left burner 5 and the fuel supply device 20 for the back burner 6 are arranged side by side and fixed to the rear surface of the upper portion 52 of the panel main body 50 with screws using mounting brackets 33. . The connecting member 25 and the operation knobs 13 and 14 of the two fuel supply devices 20 are arranged in the two through holes 53, respectively.

２つの貫通穴５３の上側外周部分には、夫々、複数の導光部５４が周方向に並んで設けられる。導光部５４は、前後方向に延びる筒穴であり、本実施形態では７つずつ設けられる。夫々の導光部５４は、互いに独立に形成される。 A plurality of light guide portions 54 are provided side by side in the circumferential direction on the upper outer peripheral portions of the two through holes 53 . The light guide portions 54 are cylindrical holes extending in the front-rear direction, and seven of them are provided in this embodiment. Each light guide part 54 is formed independently of each other.

上側部分５２の後面には、表示基板６０が固定される。表示基板６０は貫通穴５３に干渉しないように下端部が二双の円弧状に形成される。表示基板６０の前面には複数のＬＥＤ６１が実装され、下端部に沿って二双の円弧状に並んで配置される。本実施形態では、２つの円弧に沿って、夫々７つのＬＥＤ６１が設けられる。各ＬＥＤ６１は、夫々の導光部５４の形成位置に対応する位置に設けられる。これにより、導光部５４を通過する光の強度を、１つの光源から拡散させた場合よりも強い強度に確保することができる。表示基板６０がパネル本体部５０に固定されると、表示基板６０の前面によって導光部５４の後側開口が閉じられる。複数のＬＥＤ６１は、夫々、導光部５４内に配置される。導光部５４が前後方向に延びるので、導光部５４を通過することができるＬＥＤ６１の光は、前方へ向かう光のみに制限され、光の広がりが抑制される。 A display substrate 60 is fixed to the rear surface of the upper portion 52 . The display substrate 60 has two arcuate lower ends so as not to interfere with the through holes 53 . A plurality of LEDs 61 are mounted on the front surface of the display substrate 60, and are arranged side by side in two arcs along the lower end. In this embodiment, seven LEDs 61 are provided along each of the two arcs. Each LED 61 is provided at a position corresponding to the formation position of each light guide portion 54 . As a result, the intensity of the light passing through the light guide portion 54 can be ensured to be higher than when the light is diffused from a single light source. When the display substrate 60 is fixed to the panel body portion 50 , the rear opening of the light guide portion 54 is closed by the front surface of the display substrate 60 . The plurality of LEDs 61 are arranged inside the light guide section 54 respectively. Since the light guide portion 54 extends in the front-rear direction, the light from the LED 61 that can pass through the light guide portion 54 is restricted to forward light only, thereby suppressing the spread of the light.

図４、図５に示すように、化粧パネル８０は、パネル本体部５０の上側部分５２の前側に組み付けられる板状体である。化粧パネル８０は正面視略長方形状であり、上端部にスライドロック８５を備える。化粧パネル８０を上側部分５２に組み付けたとき、スライドロック８５を右側にスライドすると、化粧パネル８０がパネル本体部５０に固定される。 As shown in FIGS. 4 and 5 , the decorative panel 80 is a plate-like body attached to the front side of the upper portion 52 of the panel main body 50 .

The inner diameter D3 of the opening 86 is larger than the outer diameter D2 of the operating knob 14 (see FIG. 4). Operation knobs 13 and 14 are arranged in the two openings 86, respectively. Seven circular holes 83 penetrating in the front-rear direction are formed side by side in the circumferential direction in the upper outer peripheral portions of the two openings 86 . Each hole portion 83 is provided at a position corresponding to each formation position of the light guide portion 54 when the decorative panel 80 is assembled to the upper portion 52 of the panel body portion 50 .

各穴部８３には、透光部材８４の透光部８８が配置される。透光部材８４は、例えば透明な樹脂によって形成された部材であり、前後方向に円柱状に延びる７つの透光部８８が支持部８９によって一体に支持される。支持部８９は、化粧パネル８０の背面に形成された溝部８７に位置決めされ、各透光部８８は各穴部８３に係合する。支持部８９の裏面側には、固定部９０が設けられる。固定部９０は板状で、化粧パネル８０に接着剤で固定される。透光部８８は、ＬＥＤ６１から出射され、導光部５４を介して後面から入射する光を、内部を通して前面に導き、前面から前方へ出射する。また、化粧パネル８０の背面側には、開口部８６の形成位置を中心に前方へ向けて段状に凹む円形の段部８１が形成される。段部８１は、開口部８６の縁部分に設けられる。段部８１内には、鍔付筒部７０の目隠部７８の先端部９５が配置され、鍔付筒部７０を位置決めする。 A light-transmitting portion 88 of a light-transmitting member 84 is arranged in each hole portion 83 . The light-transmitting member 84 is a member made of, for example, transparent resin, and seven light-transmitting portions 88 extending in the front-rear direction in a cylindrical shape are integrally supported by support portions 89 . The support portion 89 is positioned in a groove portion 87 formed on the back surface of the decorative panel 80 , and each translucent portion 88 is engaged with each hole portion 83 . A fixing portion 90 is provided on the back side of the support portion 89 . The fixed part 90 is plate-shaped and is fixed to the decorative panel 80 with an adhesive. The light transmitting portion 88 guides the light emitted from the LED 61 and entering from the rear surface through the light guide portion 54 to the front surface through the inside thereof, and emits the light forward from the front surface. Further, on the rear side of the decorative panel 80, a circular stepped portion 81 is formed which is recessed in a stepped shape toward the front around the position where the opening 86 is formed. The step portion 81 is provided at the edge portion of the opening portion 86 .

The flange portion 76 is formed along the entire circumference except for the light passing portion 77 . In addition, the flange portion 76 may be formed in a part of the circumferential direction except for the light passing portion 77 . In this case, the flange portion 76 should be formed in a range that covers at least the portion overlapping the light guide portions 54 on the front side of the seven light guide portions 54 in the rotation range of the flanged tubular portion 70 about the axis AX. good.

目隠部７８は、本体部７１の前端部にて円環状に設けられ、フランジ部７６よりも前方に突出する。目隠部７８の外径Ｄ６は、化粧パネル８０の開口部８６の内径Ｄ３よりも大きい。目隠部７８の内径Ｄ７は、本体部７１の内径Ｄ５よりも小さい。すなわち目隠部７８は、本体部７１の前端部において内向きに膨出する。目隠部７８は、内周面に、曲面部９１とテーパ部９２を有する。曲面部９１は、径方向内向きに膨出する曲面状を呈し、前方から後方へ向けて内径が小さくなる。テーパ部９２は、曲面部９１に接続し、後方へ向けて徐々に内径が大きくなるテーパ状を呈する。目隠部７８の内周面は、曲面部９１とテーパ部９２との接続部９３にて最小内径となる。目隠部７８の内径Ｄ７は、接続部９３における内径、すなわち目隠部７８の最小内径をいう。また、目隠部７８の内径Ｄ７は、操作つまみ１４の外径Ｄ２よりも大きく、開口部８６の内径Ｄ３よりも小さい。 The blindfold portion 78 is provided in an annular shape at the front end portion of the main body portion 71 and protrudes forward from the flange portion 76 . The outer diameter D6 of the blind portion 78 is larger than the inner diameter D3 of the opening 86 of the decorative panel 80 . The inner diameter D7 of the blind portion 78 is smaller than the inner diameter D5 of the main body portion 71 . That is, the blindfold portion 78 bulges inward at the front end portion of the main body portion 71 . The blind portion 78 has a curved portion 91 and a tapered portion 92 on its inner peripheral surface. The curved surface portion 91 has a curved surface shape that bulges inward in the radial direction, and the inner diameter decreases from the front to the rear. The tapered portion 92 is connected to the curved surface portion 91 and has a tapered shape in which the inner diameter gradually increases toward the rear. The inner peripheral surface of the blind portion 78 has a minimum inner diameter at the connecting portion 93 between the curved surface portion 91 and the tapered portion 92 . The inner diameter D7 of the blind portion 78 refers to the inner diameter of the connection portion 93 , that is, the minimum inner diameter of the blind portion 78 . In addition, the inner diameter D7 of the blind portion 78 is larger than the outer diameter D2 of the operation knob 14 and smaller than the inner diameter D3 of the opening 86 .

図８に示すように、パネル装置９Ｂを組み立てた場合に、鍔付筒部７０のフランジ部７６と目隠部７８は、化粧パネル８０とパネル本体部５０との間に配置される。目隠部７８の先端部９５は、化粧パネル８０の段部８１内に配置される。段部８１の後面（段部８１を構成する凹部の底部）には、目隠部７８の先端部９５が当接又は近接する。フランジ部７６が貫通穴５３の前面に当接又は近接するので、目隠部７８は、化粧パネル８０とパネル本体部５０との間にて前後方向に位置決めされる。また、段部８１の内径Ｄ８は、目隠部７８の先端部９５の外径よりも大きい。なお、本実施形態では目隠部７８の外径Ｄ６は目隠部７８の前後方向において一定であり、先端部９５の外径は、目隠部７８の外径Ｄ６と同径であるものとする。故に、操作部２１の操作の際に、操作つまみ１４が軸ずれした場合に、目隠部７８は、先端部９５が段部８１内に配置された状態を維持したまま、操作つまみ１４と共に、段部８１の内径Ｄ８と目隠部７８の先端部９５の外径Ｄ６との径差の範囲内で、軸線ＡＸの径方向に軸ずれすることができる。軸ずれによって間隙Ｇが偏り、大きな隙間が生じた場合でも、間隙Ｇ内の奥は、目隠部７８によって見えにくい。 As shown in FIG. 8, when the panel device 9B is assembled, the flange portion 76 and blindfold portion 78 of the flanged tubular portion 70 are arranged between the decorative panel 80 and the panel body portion 50 . A tip portion 95 of the blindfold portion 78 is arranged within the stepped portion 81 of the decorative panel 80 . A front end portion 95 of the blind portion 78 abuts on or approaches the rear surface of the stepped portion 81 (the bottom portion of the recess forming the stepped portion 81). Since the flange portion 76 contacts or approaches the front surface of the through hole 53 , the blindfold portion 78 is positioned between the decorative panel 80 and the panel body portion 50 in the front-rear direction. In addition, the inner diameter D8 of the stepped portion 81 is larger than the outer diameter of the distal end portion 95 of the blind portion 78 . In this embodiment, the outer diameter D6 of the blind portion 78 is constant in the front-rear direction of the blind portion 78, and the outer diameter of the tip portion 95 is the same as the outer diameter D6 of the blind portion 78. do. Therefore, when the operation knob 14 is displaced from the axis when the operation portion 21 is operated, the blindfold portion 78 can be operated together with the operation knob 14 while maintaining the state in which the distal end portion 95 is arranged in the stepped portion 81. Within the range of the difference in diameter between the inner diameter D8 of the stepped portion 81 and the outer diameter D6 of the distal end portion 95 of the blind portion 78, the axial displacement can be achieved in the radial direction of the axis AX. Even when the gap G is biased due to axial misalignment and a large gap is generated, the back of the gap G is difficult to see due to the blind portion 78 .

このような構成のパネル装置９Ｂにおいて、操作つまみ１４の外周面と、化粧パネル８０の開口部８６の内周面との間には、操作つまみ１４の円滑な操作を確保するための間隙Ｇが設けられている。目隠部７８の内径Ｄ７は開口部８６の内径Ｄ３よりも小さいので、パネル装置９Ｂを前方から見た場合、間隙Ｇ内には目隠部７８が見え、目隠部７８より後方の部材が目隠部７８に遮られて視認しにくい。更に、操作つまみ１４の外周面は、前端位置から、少なくとも操作つまみ１４が待機位置にあるときに接続部９３に対向する対向位置よりも後側の位置にかけて、外径が大きくなるテーパ状を呈する。故に、パネル装置９Ｂを前方から見た場合、間隙Ｇ内は、対向位置の前側に目隠部７８が見え、対向位置の後側に操作つまみ１４の外周面が見える。目隠部７８の内周面と操作つまみ１４の外周面との隙間は極めて小さくなるので、操作つまみ１４の外周面がテーパ状でない場合と比べ、後方の部材は、より視認しにくい。 In the panel device 9B having such a configuration, a gap G is provided between the outer peripheral surface of the operation knob 14 and the inner peripheral surface of the opening 86 of the decorative panel 80 to ensure smooth operation of the operation knob 14. is provided. Since the inner diameter D7 of the blind portion 78 is smaller than the inner diameter D3 of the opening portion 86, when the panel device 9B is viewed from the front, the blind portion 78 can be seen in the gap G, and the members behind the blind portion 78 can be seen. It is difficult to visually recognize because it is blocked by the blindfold portion 78 . Further, the outer peripheral surface of the operation knob 14 has a tapered shape in which the outer diameter increases from the front end position to at least a position on the rear side of the facing position facing the connection portion 93 when the operation knob 14 is in the standby position. . Therefore, when the panel device 9B is viewed from the front, in the gap G, the blind portion 78 can be seen on the front side of the facing position, and the outer peripheral surface of the operation knob 14 can be seen on the rear side of the facing position. Since the gap between the inner peripheral surface of the blind portion 78 and the outer peripheral surface of the operation knob 14 is extremely small, compared to the case where the outer peripheral surface of the operation knob 14 is not tapered, the rear members are more difficult to see.

また、目隠部７８の内径Ｄ７は操作つまみ１４の外径Ｄ２よりも大きい。故に、操作部２１に対する操作において、目隠部７８は操作つまみ１４に接触しにくく、操作つまみ１４に対する操作を妨げない。そして、点火時及び消火時に、操作つまみ１４は押し込み操作され、前後方向に変位する。目隠部７８の内周面は曲面部９１とテーパ部９２を有するので、接続部９３から離れるほど操作つまみ１４の表面から遠ざかる。故に、操作つまみ１４が前後方向に変位するときに軸ずれした場合、操作つまみ１４の外周面には接続部９３のみが接触し、他の部分は接触しにくい。 In addition, the inner diameter D7 of the blind portion 78 is larger than the outer diameter D2 of the operation knob 14. As shown in FIG. Therefore, when the operation portion 21 is operated, the blind portion 78 is less likely to come into contact with the operation knob 14 and does not interfere with the operation of the operation knob 14 . At the time of ignition and extinguishing, the operation knob 14 is pushed and displaced in the front-rear direction. Since the inner peripheral surface of blind portion 78 has curved surface portion 91 and tapered portion 92 , the farther away from connecting portion 93 , the farther away from the surface of operation knob 14 . Therefore, if the operation knob 14 is displaced from its axis when displaced in the front-rear direction, only the connecting portion 93 contacts the outer peripheral surface of the operation knob 14, and other portions are less likely to contact.

なお、表示基板６０の複数のＬＥＤ６１は、安全弁４８の開放時に全てが点灯する。操作つまみ１４が操作位置にあるとき、火力調節カム２６は操作つまみ１４と連結し、操作つまみ１４の回動操作に応じて左バーナ５の火力を調節することができる。操作つまみ１４が回転すると、鍔付筒部７０はＬＥＤ操作部材３６を介して火力調節カム２６と共に軸線ＡＸの周りを回転する。フランジ部７６は、光通過部７７と重なる位置を除き、導光部５４を介して前方に照射されるＬＥＤ６１の光を遮る。操作つまみ１４が回転され、火力が変更されると、光通過部７７が軸線ＡＸの周りを周方向に移動し、ＬＥＤ６１の光が通過可能となる導光部５４が周方向の並びに従って変更される。光通過部７７を通過したＬＥＤ６１の光は、導光部５４に対応する透光部材８４の透光部８８を介すことによって、化粧パネル８０の表面において点灯表示される。よってパネル装置９Ｂは、化粧パネル８０の表面においてＬＥＤ６１の光が点灯した位置によって、火力表示を行うことができる。操作つまみ１３、及びパネル装置９Ａの操作つまみ１１の回動量に対応する火力表示についても同様である。 All of the plurality of LEDs 61 on the display substrate 60 are lit when the safety valve 48 is opened. When the operating knob 14 is at the operating position, the heating power adjusting cam 26 is connected to the operating knob 14 so that the heating power of the left burner 5 can be adjusted according to the turning operation of the operating knob 14 . When the operation knob 14 rotates, the flanged tubular portion 70 rotates about the axis AX together with the heating power control cam 26 via the LED operation member 36 . The flange portion 76 blocks the light from the LED 61 emitted forward through the light guide portion 54 except for the position overlapping the light passage portion 77 . When the operation knob 14 is rotated to change the heating power, the light passage portion 77 moves in the circumferential direction around the axis AX, and the light guide portion 54 through which the light of the LED 61 can pass is changed according to the circumferential arrangement. be. The light from the LED 61 that has passed through the light passage portion 77 is illuminated on the surface of the decorative panel 80 through the light transmission portion 88 of the light transmission member 84 corresponding to the light guide portion 54 . Therefore, the panel device 9B can display the thermal power according to the position of the light of the LED 61 on the surface of the decorative panel 80 . The same applies to the operation knob 13 and the heating power display corresponding to the amount of rotation of the operation knob 11 of the panel device 9A.

ＬＥＤ６１の光が、導光部５４、光通過部７７、透光部８８を通過する際に、乱反射によって開口部８６内に向かう場合がある。鍔付筒部７０の目隠部７８は、フランジ部７６よりも前方に突出し、先端部９５が化粧パネル８０の段部８１内に配置される。このため、乱反射した光は、光通過部７７から開口部８６内に向かった場合、目隠部７８に遮られるので、開口部８６内には届かない。 When the light from the LED 61 passes through the light guide portion 54, the light passage portion 77, and the light transmission portion 88, it may be directed into the opening 86 due to irregular reflection. The blind portion 78 of the flanged tubular portion 70 projects forward from the flange portion 76 , and the distal end portion 95 is disposed within the stepped portion 81 of the decorative panel 80 . Therefore, when the diffusely reflected light travels from the light passing portion 77 into the opening 86 , the light is blocked by the blind portion 78 and does not reach the opening 86 .

以上説明したように、操作つまみ１４は、少なくともガスの供給時にはパネル装置９Ｂの前面に対して突出し、ガスの供給量が調整される場合には回動操作される。故に、操作つまみ１４の外周面と、化粧パネル８０の開口部８６の内周面との間には、円滑な操作のための間隙Ｇが設けられる。目隠部７８の内径Ｄ７は、操作つまみ１４の外径Ｄ２よりも大きく、開口部８６の内径Ｄ３よりも小さい。よって、ガスコンロ１を前方から見たとき、操作つまみ１４と開口部８６の間隙Ｇ内は、目隠部７８に遮られて奥が見えにくくなるので、ガスコンロ１の美観を損ねない。また、目隠部７８は鍔付筒部７０と一体に設けられるので、別体に設けた場合と比べて部品点数を減らすことができ、且つ目隠部７８を鍔付筒部７０と別体で設けた場合に化粧パネル８０において必要となる目隠部７８の取付部位の加工に要する工数を削減できるので、ガスコンロ１の製造コストを低減することができる。 As described above, the operation knob 14 protrudes from the front surface of the panel device 9B at least when gas is supplied, and is rotated when the amount of gas supply is adjusted. Therefore, a gap G is provided between the outer peripheral surface of the operation knob 14 and the inner peripheral surface of the opening 86 of the decorative panel 80 for smooth operation. The inner diameter D7 of the blind portion 78 is larger than the outer diameter D2 of the operation knob 14 and smaller than the inner diameter D3 of the opening 86. As shown in FIG. Therefore, when the gas stove 1 is viewed from the front, the inside of the gap G between the operation knob 14 and the opening 86 is blocked by the blind part 78, making it difficult to see the depth, so that the appearance of the gas stove 1 is not spoiled. In addition, since the blindfold portion 78 is provided integrally with the flanged tubular portion 70, the number of parts can be reduced compared to the case where the blindfolded portion 78 is provided separately. Since it is possible to reduce the number of man-hours required for processing the mounting portion of the blindfold portion 78 that is required in the decorative panel 80 when provided in , the manufacturing cost of the gas stove 1 can be reduced.

操作つまみ１４の回動操作に応じて本体部７１が回動すると、目隠部７８は、操作つまみ１４の外周面に沿って回動する。目隠部７８は、先端部９５が化粧パネル８０の段部８１内に配置され、回動時に段部８１によって位置決められるので、鍔付筒部７０の回動が安定する。操作つまみ１４が回動する時も、目隠部７８の内周面と操作つまみ１４の外周面との間に間隙Ｇが確保されるので、間隙Ｇ内の奥が目隠部７８によって見えにくく、ガスコンロ１は美観を損ねない。また、間隙Ｇの確保により、目隠部７８は、操作つまみ１４の回動操作に対し接触抵抗を与えにくいので、操作部２１の操作性を確保できる。 When the body portion 71 rotates according to the rotation operation of the operation knob 14 , the blindfold portion 78 rotates along the outer peripheral surface of the operation knob 14 . The tip portion 95 of the blindfold portion 78 is disposed within the stepped portion 81 of the decorative panel 80 and is positioned by the stepped portion 81 during rotation, so that rotation of the flanged tubular portion 70 is stabilized. Even when the operation knob 14 rotates, the gap G is ensured between the inner peripheral surface of the blind portion 78 and the outer peripheral surface of the operation knob 14, so that the back of the gap G is hard to be seen by the blind portion 78. , The gas stove 1 does not spoil the aesthetic appearance. Further, by ensuring the gap G, the blind portion 78 does not easily give contact resistance to the turning operation of the operation knob 14, so that the operability of the operation portion 21 can be ensured.

化粧パネル８０の後面における段部８１の内径Ｄ８は、目隠部７８の先端部９５の外径（本実施形態では目隠部７８の外径Ｄ６と同径）よりも大きい。故に、目隠部７８は、段部８１の内径Ｄ８と目隠部７８の先端部９５の外径Ｄ６との径差の範囲内で、開口部８６の中心軸に対する軸ずれが許容される。この構成により、開口部８６の中心軸に対する操作つまみ１４の軸ずれに合わせて目隠部７８も軸ずれすることができるので、軸ずれによって間隙Ｇが偏り大きな隙間が生じた場合でも、間隙Ｇ内の奥が目隠部７８によって見えにくく、ガスコンロ１は美観を損ねない。また、目隠部７８の前面が段部８１の後面に当接又は近接した状態であるので、振動等による目隠部７８の軸ずれを抑制し、目隠しの効果を維持することができる。 The inner diameter D8 of the stepped portion 81 on the rear surface of the decorative panel 80 is larger than the outer diameter of the tip portion 95 of the blind portion 78 (the same diameter as the outer diameter D6 of the blind portion 78 in this embodiment). Therefore, the blind portion 78 is allowed to deviate from the central axis of the opening 86 within the range of the diameter difference between the inner diameter D8 of the stepped portion 81 and the outer diameter D6 of the distal end portion 95 of the blind portion 78 . With this configuration, the blind portion 78 can also be displaced along with the axial displacement of the operation knob 14 with respect to the central axis of the opening 86. The blindfold part 78 makes it difficult to see the inner part, and the gas stove 1 does not spoil the appearance. Further, since the front surface of the blind portion 78 is in contact with or in close proximity to the rear surface of the step portion 81, axial deviation of the blind portion 78 due to vibration or the like can be suppressed, and the blind effect can be maintained.

目隠部７８は、接続部９３において最も内径が小さい。故に、操作つまみ１４と開口部８６の間隙Ｇ内は、接続部９３よりも後側が見えにくく、ガスコンロ１の美観を損ねない。また、目隠部７８の内周面は、接続部９３において操作つまみ１４の表面に最も近接し、曲面部９１とテーパ部９２において接続部９３から離れるほど操作つまみ１４の表面から遠ざかる。操作部２１の操作において目隠部７８が操作つまみ１４に接触しても、接続部９３が操作つまみ１４に接触し、曲面部９１とテーパ部９２を含む他の部分が接触することがないので、操作つまみ１４にかかる接触抵抗は小さい。故に、点火操作を行うとき、操作つまみ１４は前後方向に円滑に変位することができる。 The blind portion 78 has the smallest inner diameter at the connecting portion 93 . Therefore, in the gap G between the operation knob 14 and the opening 86, it is difficult to see the rear side of the connecting portion 93, and the appearance of the gas stove 1 is not spoiled. The inner peripheral surface of blind portion 78 is closest to the surface of operation knob 14 at connection portion 93 , and becomes farther from the surface of operation knob 14 at curved surface portion 91 and tapered portion 92 as it moves away from connection portion 93 . Even if the blind portion 78 contacts the operation knob 14 during operation of the operation portion 21, the connection portion 93 contacts the operation knob 14, and other portions including the curved surface portion 91 and the tapered portion 92 do not contact each other. , the contact resistance applied to the operation knob 14 is small. Therefore, when performing ignition operation, the operation knob 14 can be smoothly displaced in the front-rear direction.

操作つまみ１４が待機位置にあるとき、操作つまみ１４と開口部８６の間隙Ｇは、接続部９３に対向する対向位置において最も小さい。更に、操作つまみ１４の外周面は、前端位置から対向位置よりも後側の位置にかけて外径が大きくなるテーパ状を呈する。このため、前方から操作つまみ１４と開口部８６の間隙Ｇ内を覗いた場合に、対向位置の前側には目隠部７８が見え、対向位置の後側には操作つまみ１４の外周面が見え、他の部位が見えにくいので、ガスコンロ１は美観を損ねない。 When the operating knob 14 is at the standby position, the gap G between the operating knob 14 and the opening 86 is the smallest at the facing position facing the connecting portion 93 . Furthermore, the outer peripheral surface of the operation knob 14 has a tapered shape in which the outer diameter increases from the front end position to the position on the rear side of the facing position. Therefore, when looking into the gap G between the operation knob 14 and the opening 86 from the front, the blind portion 78 can be seen on the front side of the facing position, and the outer peripheral surface of the operation knob 14 can be seen on the rear side of the facing position. , Since other parts are hard to see, the gas stove 1 does not spoil the appearance.

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。化粧パネル８０の段部８１はなくてもよい。この場合、目隠部７８の先端部９５は、化粧パネル８０の後面に当接又は近接してもよい。また、目隠部７８は、本体部７１の前端部から前方に突出しなくてもよい。この場合、目隠部７８は、本体部７１の前端部から径方向内向き、又は前方斜め径方向内向きに突出してもよい。目隠部７８の内周面において、曲面部９１とテーパ部９２はなくてもよいし、いずれか一方のみ形成されてもよい。操作つまみ１４の外周面は、テーパ状でなく、外径が一定の筒状であってもよい。また、操作つまみ１４の外周面がテーパ状である場合において、対向位置における外径が目隠部７８の内径Ｄ７よりも小さいのであれば、対向位置よりも後側の位置における外径が、目隠部７８の内径Ｄ７よりも大きくてもよい。この場合、間隙Ｇ内は、目隠部７８によって確実に奥が見えないようにすることができる。 The present invention is not limited to the above embodiments, and various modifications are possible. The stepped portion 81 of the decorative panel 80 may be omitted. In this case, the tip portion 95 of the blindfold portion 78 may be in contact with or close to the rear surface of the decorative panel 80 . Also, the blindfold portion 78 does not need to protrude forward from the front end portion of the main body portion 71 . In this case, the blind portion 78 may protrude radially inward from the front end portion of the main body portion 71 or diagonally forward and radially inward. On the inner peripheral surface of the blind portion 78, the curved surface portion 91 and the tapered portion 92 may be omitted, or only one of them may be formed. The outer peripheral surface of the operation knob 14 may be cylindrical with a constant outer diameter instead of being tapered. Further, in the case where the outer peripheral surface of the operation knob 14 is tapered, if the outer diameter at the facing position is smaller than the inner diameter D7 of the blind portion 78, the outer diameter at the rear side of the facing position is equal to the blind portion. It may be larger than the inner diameter D7 of the hidden portion 78 . In this case, the interior of the gap G can be reliably prevented from being seen by the blind portion 78 .
