A first lever 17 for pressing and opening the water valve 3 which intervenes in the water channel 5 is provided, and when the rotary knob 14 is rotated to the “water position” provided outside the adjustment angle of the hot water temperature, the cam plate 16 is provided. A protrusion 18 is provided for switching the first lever 17 to the push valve opening position of the water valve 3 when pushed by the lever, and when the turning knob is turned to the "water position", the push button is interlocked with this. A lock member 19 for preventing the forward movement of the button 13 is provided, and when the push button 13 is further pressed, the push button 13 is oscillated in synchronization with the push button 13, and the cam plate 16 is projected on the turning locus so that the water knob of the turning knob 14 moves.

When moving, the step portion 22a on the front surface of the claw portion 22b engages with the tail end 17a of the first lever 17 and pushes it forward, and the water valve 3 is pushed open by the other end 17b.
【００１４】 そして前記突片１８は該第１レバ１７と同軸上に軸支してその前面に臨むごと く設けた第３の揺動レバ２６上に設け、これを前記回動つまみ１４を「水位置」 まで回動操作したときカム板１６に押されて後退動する位置に臨ませて、該突片 １８の後退動によれば、第３の揺動レバ２６を介して押杆１３ａの押操作とは別 に第１レバ１７を水弁３の押圧開弁位置に切換え得るようにし、前記ロック部材 １９は該押ボタン１３を備える押杆１３ａに形成した透孔１３ｂ内に挿嵌される 鈎杆１９ａからなり、該鈎杆１９ａを該第３の揺動レバ２６の後端から突出する 突起２８と係合させ、前記突片１８がカム板１６に押されて後退動するとき、こ れに押されて該鈎杆１９ａがばね１９ｂに抗して該透孔１３ｂ内に嵌合するごと くした。The projecting piece 18 is provided on a third swing lever 26 that is coaxially supported by the first lever 17 and is provided so as to face the front surface of the first lever 17. When the protrusion 18 is moved backward when the cam plate 16 pushes the cam 13 when it is rotated to the "water position", the backward movement of the protrusion 18 causes the pushing lever 13a to move through the third swing lever 26.

Is engaged with a projecting piece 13c projecting from a pushing rod 13a pushed by the push button 13, and a hook portion 20a is provided at the other end. When the push button 13 is pressed, the hook portion 20a is The cam plate 16 is projected into the rotation locus to prevent the rotation knob 14 from rotating to the "water position".
【００１６】 尚図示するものでは主ガス通路７ａにガス流量制御弁２９を備え、前記水量調 節弁４による水量の変化で出湯温度の調節をするのみならず主ガスバ―ナ６ａに 供給されるガス量を調節することも出湯温度の調節を行なわせ得るようにした。 この調節を説明すると該ガス流量制御弁２９は前方に押杆２９ａを突出させた プッシュ型に構成してプッシュによればガス量が絞られるもので、その操作は、 その前面に臨ませこれを押圧する揺動レバ３０と該レバ３０に設けたカム３０ａ ，３０ｂに係合する、前記回動つまみ１４の回動軸１４ａ上に設けた前記カム１ ６とは別個のカム３３とガス絞り専用の回動つまみ３１の回動軸３１ａのカム３ ２とによって行なう。In the illustrated example, a gas flow rate control valve 29 is provided in the main gas passage 7a, and the hot water temperature is adjusted not only by the change of the water amount by the water amount adjusting valve 4 but also by the main gas burner 6a. By adjusting the amount of gas, the temperature of the tap water can be adjusted. To explain this adjustment, the gas flow control valve 29 is of a push type in which a pushing rod 29a is projected forward, and the amount of gas is reduced by pushing. Dedicated to the swing lever 30 for pressing and the cam 16 provided on the rotary shaft 14a of the rotary knob 14 that engages with the cams 30a 1 and 30b provided on the lever 30 It is performed by the cam 32 of the rotary shaft 31a of the rotary knob 31.
【００１７】 これを説明すると回動つまみ３１を反時計方向に回動操作すると、その軸３１ ａ上に設けたカム３２で該揺動レバ３０が直ちに揺動してガス流量制御弁２９が 押圧されてガス流量が絞られると共に回動つまみ１４の反時計方向の回動操作に よれば、水量が増すと共に該軸の予定の回動位置で該カム３３が揺動レバ３３上 のカム３０ｂに作用して該プッシュレバ３０を押し前記ガス流量を絞って出湯温 度が下がる。 尚前述の実施例では、第１レバ１７を水弁３の押圧開弁位置に切 換える突片１８を、第３のレバ２６上に設けたが、これは第９図並びに第１０に 示すごとく第１のレバ１７上に設けて該突片１８がカム板１６によって押される ときこのレバ１７を水弁３を開弁する位置に保たせるようにしても良く、この場 合は前記第２のレバ―２０をロック部材１９として活用させれば良い。即ちこの 場合第９図に示すごとく第２のレバ２０を前述するごとく押ボタン１３から押さ れる押杆１３ａから突出する突起１３ｃに係合させると共に該回動操作つまみ１ ４を「水位置」に回動操作するとき、該カム板１６の背面に鈎部２０ａの前端が 当接するようにすればこの状態では該第２のレバ２０は揺動不能となり、結局押 ボタン１３は押操作不能のロック状態となる。To explain this, when the rotary knob 31 is rotated counterclockwise, the swing lever 30 immediately swings by the cam 32 provided on the shaft 31a thereof, and the gas flow control valve 29 is pressed. As a result, the gas flow rate is reduced and the counterclockwise rotation operation of the rotary knob 14 increases the amount of water and causes the cam 33 to move to the cam 30b on the swing lever 33 at the predetermined rotary position of the shaft. In operation, the push lever 30 is pushed and the flow rate of the gas is reduced to lower the hot water temperature. In the above-described embodiment, the protruding piece 18 for switching the first lever 17 to the pressure valve opening position of the water valve 3 is provided on the third lever 26, but this is as shown in FIGS. 9 and 10. The lever 17 may be provided on the first lever 17 so as to keep the lever 17 at the position where the water valve 3 is opened when the protrusion 18 is pushed by the cam plate 16, and in this case, the second lever 17 is held. The lever 20 may be used as the lock member 19. That is, in this case, as shown in FIG. 9, the second lever 20 is engaged with the projection 13c protruding from the push rod 13a pushed by the push button 13 as described above, and the rotary operation knob 14 is set to the "water position". When the front end of the hook portion 20a is brought into contact with the back surface of the cam plate 16 during the turning operation, the second lever 20 cannot be swung in this state, and the push button 13 cannot be pushed. It becomes a state.
【００１８】 尚、前記押ボタン１３は、１個のみとしたが、点火操作を行なう点火用ボタン と、中間位置での該係止を解いて始端位置に復帰させる消火用のボタンを併設す る式とすることも可能であること申すまでもない。Although only one push button 13 is provided, an ignition button for performing an ignition operation and a fire extinguishing button for releasing the lock at the intermediate position and returning to the starting end position are provided. It goes without saying that it can be a formula.
【００１９】 尚、図面で３４はパイロットバ―ナ６ｃに臨ませた点火器、３５は常火バ―ナ ６ｂに臨ませた熱電対、３６回動つまみ１４のストッパ、３７は前記突片１８並 びに鈎部２０ａが臨む透孔を示す。In the drawing, 34 is an igniter facing the pilot burner 6c, 35 is a thermocouple facing the normal fire burner 6b, 36 is a stopper of the rotary knob 14, and 37 is the protruding piece 18 The through holes that the hook portions 20a face are shown in parallel.
【００２０】 次に本装置の作動を第１図乃至第８図に示す実施例につき説明する。Next, the operation of this apparatus will be described with reference to the embodiment shown in FIGS. 1 to 8.
【００２１】 今押ボタン１３を始端位置Ａから終端位置Ｂ側に押圧操作するときは、これに 押されてガス弁９が押圧開弁されると共に、終端位置で電磁安全弁８を押圧開弁 し、且つパイロット弁１２を開き、更に点火器３４の作動回路に介入するスイッ チ（図示しない）を閉じ、点火器３４に火花を得る。このためパイロットバ―ナ ６ｃ並びに常火バ―ナ６ｂに着火する。そしてこの押圧を解くときは、一般に知 られるごとく強制保持回路により開弁保持されると共にその後は常火バ―ナ６ｂ に臨ませた熱電対３５の起電力により開弁保持されると共に主ガス弁９は押ボタ ン１３のプッシュプッシュ機構１５による中間位置Ｃへの係止により開弁状態を 保つ。更に該押ボタン１３の中間位置への復帰により爪片２２の爪部２２ｂで第 １レバ１７の一端１７ａを押すので、第６図に示すごとく第１レバ１７が傾動し 、第５図に示すごとく、その他端で水弁３を押圧開弁する。このため熱交換器２ に通水されると共に、水圧応動弁１１が開くため主ガスバ―ナ６ａで燃焼が始ま る。従って出湯口から出湯される。When the push button 13 is pushed from the start end position A to the end position B, the gas valve 9 is pushed and opened by the push button 13 and the electromagnetic safety valve 8 is pushed and opened at the end position. , And the pilot valve 12 is opened, and the switch (not shown) intervening in the operating circuit of the igniter 34 is closed, and the igniter 34 is sparked. Therefore, the pilot burner 6c and the constant-fire burner 6b are ignited. When releasing this pressure, as is generally known, the valve is held open by the forced holding circuit, and thereafter, the valve is held open by the electromotive force of the thermocouple 35 facing the normal-fire burner 6b and the main gas valve is opened. Reference numeral 9 keeps the valve open state by locking the push button 13 at the intermediate position C by the push-push mechanism 15. Further, when the push button 13 returns to the intermediate position, the one end 17a of the first lever 17 is pushed by the claw portion 22b of the claw piece 22, so that the first lever 17 tilts as shown in FIG. 6 and shown in FIG. Similarly, the water valve 3 is pressed and opened at the other end. As a result, water is passed through the heat exchanger 2 and the water pressure responsive valve 11 opens so that combustion starts in the main gas burner 6a. Therefore, hot water is discharged from the hot water outlet.
【００２２】 尚この場合出湯温度調節を行なうには、回動つまみ３１によりガス流量調節弁 ２９の絞り度合を調節し、又は回動つまみ１４により水量を変化させ又はこれに 引続く水量の調節とガス流量の調節とを同時に行なわせれば良い。In this case, in order to adjust the hot water temperature, the rotary knob 31 is used to adjust the degree of throttling of the gas flow rate control valve 29, or the rotary knob 14 is used to change the amount of water or to adjust the amount of water thereafter. The gas flow rate may be adjusted at the same time.
【００２３】 尚、押ボタン１３を押操作した或いは押圧を解除した中間位置Ｃに係止される 状態では、第５図に示すごとくこれに連動して第２のレバ２０が揺動しこれに設 けた鈎部２０ａがカム板１６の回動軌跡内に臨むため、該回動つまみ１４の「水 位置」への回動は阻止される。In the state where the push button 13 is pushed or released and is locked at the intermediate position C, as shown in FIG. 5, the second lever 20 swings in conjunction with this and the second lever 20 swings. Since the hook portion 20a thus provided faces the turning locus of the cam plate 16, the turning knob 14 is prevented from turning to the "water position".
【００２４】 次いで出湯を停止させるには、押ボタン１３を再押操作すれば良く、かくすれ ば、プッシュプッシュ機構１５による係止を解かれて、始端位置Ａに復帰する結 果ガス弁９が閉じると共に始端位置Ａへのもどりに際し爪片２２の斜面２２ｄが 透孔２５に嵌入して爪片２２がばね２４に抗して時計方向に回動し、第１レバ１ ７の一端１７ａの前面の段部２２ａとの係合が解かれて第１レバ１７による水弁 ３の押圧が解かれて水弁３を閉じて出湯が停止される。Next, in order to stop the hot water discharge, it is sufficient to push the push button 13 again. In this way, the result gas valve 9 that returns to the starting end position A after the locking by the push push mechanism 15 is released. When closing and returning to the starting end position A, the inclined surface 22d of the claw piece 22 is fitted into the through hole 25 and the claw piece 22 rotates clockwise against the spring 24, and the front surface of the one end 17a of the first lever 17 is rotated. The engagement with the stepped portion 22a is released, the pressure of the water valve 3 by the first lever 17 is released, and the water valve 3 is closed to stop tapping.
【００２５】 そしてこの状態で回動つまみ１４を「水位置」まで回動操作すれば、第６図に 示すごとくカム板１６により突片１８を後退動するため第３のレバ２６が揺動し 、これにともなって第１レバ１７を押ボタン１３の押操作とは別に水弁３の押圧 開弁位置に切換える。このため水が出湯口に得られる。When the rotary knob 14 is rotated to the “water position” in this state, the cam plate 16 causes the protruding piece 18 to move backward as shown in FIG. 6, so that the third lever 26 swings. Accordingly, the first lever 17 is switched to the pressing / opening position of the water valve 3 separately from the pressing operation of the pressing button 13. Therefore, water is obtained at the tap.
【００２６】 このときロック部材１９は該第３のレバ２６に押されて操作杆１３ａに設けた 透孔１３ｂに嵌合し押ボタン１３の押操作が出来ないようにロックする。At this time, the lock member 19 is pushed by the third lever 26 and fits into the through hole 13b provided in the operating rod 13a to lock the push button 13 so that it cannot be pushed.

Since the first lever for pressing and opening the water valve is provided, the opening operation of the water valve can be easily interlocked with the ignition operation by the push operation of the push button, and the structure is simple, and the water supply amount can be increased. A cam plate is installed on the rotary knob shaft that adjusts the hot water temperature by increasing or decreasing, and the cam is rotated when the rotary knob is rotated to the "water position" angle position outside the adjustment angle of the hot water temperature. Since the projecting piece which is pushed by the plate and switches the first lever to the pressing open position of the water valve is provided, when the rotary knob is switched to the "water position", water is obtained at the tap hole, and At this time, the push button was locked by the lock member, so water was released. It is safe because the ignition operation in this state is not performed, and when the push button is pressed, it swings in conjunction with this and protrudes on the rotation locus of the cam plate on the rotation knob shaft, and the rotation knob. Since a second lever is provided with a hook that prevents the rotation to the "water position", there is no problem of accidentally rotating it to the water position during tapping, and these operating members as a whole are It can be compacted and can be easily stored in the limited space of the water heater body.

【００１６】 尚、図示するものでは主ガス通路７ａにガス流量制御弁２９を備え、前記水量 調節弁４による水量の変化で出湯温度の調節をするのみならず主ガスバ―ナ６ａ に供給されるガス量を調節することも出湯温度の調節を行なわせ得るようにした 。 この調節を説明すると該ガス流量制御弁２９は前方に押杆２９ａを突出させた プッシュ型に構成してプッシュによればガス量が絞られるもので、その操作は、 その前面に臨ませこれを押圧する揺動レバ３０と該レバ３０に設けたカム３０ａ ，３０ｂに係合する、前記回動つまみ１４の回動軸１４ａ上に設けた前記カム１ ６とは別個のカム３３とガス絞り専用の回動つまみ３１の回動軸３１ａのカム３ ２とによって行なう。In the illustrated one, a gas flow rate control valve 29 is provided in the main gas passage 7a, and the hot water temperature is adjusted by the change of the water amount by the water amount adjusting valve 4 and is supplied to the main gas burner 6a. By adjusting the amount of gas, the temperature of the tap water can be adjusted. To explain this adjustment, the gas flow control valve 29 is of a push type in which a pushing rod 29a is projected forward, and the amount of gas is reduced by pushing. Dedicated to the swing lever 30 for pressing and the cam 16 provided on the rotary shaft 14a of the rotary knob 14 that engages with the cams 30a 1 and 30b provided on the lever 30 It is performed by the cam 32 of the rotary shaft 31a of the rotary knob 31.

As a result, the gas flow rate is reduced and the counterclockwise rotation of the rotary knob 14 increases the amount of water, and the cam 33 moves to the cam 30b on the swing lever 30 at the predetermined rotary position of the shaft. Ru lower the hot water temperature and squeeze the gas flow pushes the swing lever 30 acts.
【００１８】 尚、前記押ボタン１３は、１個のみとしたが、点火操作を行なう点火用ボタン と、中間位置での該係止を解いて始端位置に復帰させる消火用のボタンを併設す る式とすることも可能であること申すまでもない。Although only one push button 13 is provided, an ignition button for performing an ignition operation and a fire extinguishing button for releasing the lock at the intermediate position and returning to the starting end position are provided. It goes without saying that it can be a formula.
【００１９】 尚、図面で３４はパイロットバ―ナ６ｃに臨ませた点火器、３５は常火バ―ナ ６ｂに臨ませた熱電対、３６回動つまみ１４のストッパ、３７は前記突片１８並 びに鈎部２０ａが臨む透孔を示す。In the drawing, 34 is an igniter facing the pilot burner 6c, 35 is a thermocouple facing the normal fire burner 6b, 36 is a stopper of the rotary knob 14, and 37 is the protruding piece 18 The through holes that the hook portions 20a face are shown in parallel.
【００２０】 次に本装置の作動を説明する。[0020] Next, explain the operation of the present apparatus.
【００２１】 今押ボタン１３を始端位置Ａから終端位置Ｂ側に押圧操作するときは、これに 押されてガス弁９が押圧開弁されると共に、終端位置で電磁安全弁８を押圧開弁 し、且つパイロット弁１２を開き、更に点火器３４の作動回路に介入するスイッ チ（図示しない）を閉じ、点火器３４に火花を得る。このためパイロットバ―ナ ６ｃ並びに常火バ―ナ６ｂに着火する。そしてこの押圧を解くときは、一般に知 られるごとく強制保持回路により開弁保持されると共にその後は常火バ―ナ６ｂ に臨ませた熱電対３５の起電力により開弁保持されると共に主ガス弁９は押ボタ ン１３のプッシュプッシュ機構１５による中間位置Ｃへの係止により開弁状態を 保つ。更に該押ボタン１３の中間位置への復帰により爪片２２の爪部２２ｂで第 １レバー１７の一端１７ａを押すので、図６に示すごとく第１レバー１７が傾動 し、図５に示すごとく、その他端で水弁３を押圧開弁する。このため熱交換器２ に通水されると共に、水圧応動弁１１が開くため主ガスバ―ナ６ａで燃焼が始ま る。従って出湯口から出湯される。When the push button 13 is pushed from the start end position A to the end position B, the gas valve 9 is pushed and opened by the push button 13 and the electromagnetic safety valve 8 is pushed and opened at the end position. , And the pilot valve 12 is opened, and the switch (not shown) intervening in the operating circuit of the igniter 34 is closed, and the igniter 34 is sparked. Therefore, the pilot burner 6c and the constant-fire burner 6b are ignited. When releasing this pressure, as is generally known, the valve is held open by the forced holding circuit, and thereafter, the valve is held open by the electromotive force of the thermocouple 35 facing the normal-fire burner 6b and the main gas valve is opened. Reference numeral 9 keeps the valve open state by locking the push button 13 at the intermediate position C by the push-push mechanism 15. Further, since pressing the end 17a of the first levers 17 claw portion 22b of the claw 22 by the return to the intermediate position of the push button 13, the first levers 17 is tilted as shown in FIG. 6, FIG. 5 Similarly, the water valve 3 is pressed and opened at the other end. As a result, water is passed through the heat exchanger 2 and the water pressure responsive valve 11 opens so that combustion starts in the main gas burner 6a. Therefore, hot water is discharged from the hot water outlet.
【００２２】 尚この場合出湯温度調節を行なうには、回動つまみ３１によりガス流量調節弁 ２９の絞り度合を調節し、又は回動つまみ１４により水量を変化させ又はこれに 引続く水量の調節とガス流量の調節とを同時に行なわせれば良い。In this case, in order to adjust the hot water temperature, the rotary knob 31 is used to adjust the degree of throttling of the gas flow rate control valve 29, or the rotary knob 14 is used to change the amount of water or to adjust the amount of water thereafter. The gas flow rate may be adjusted at the same time.
【００２３】 尚、押ボタン１３を押操作した或いは押圧を解除した中間位置Ｃに係止される 状態では、図５に示すごとくこれに連動して第２レバー２０が揺動しこれに設け た鈎部２０ａがカム板１６の回動軌跡内に臨むため、該回動つまみ１４の「水位 置」への回動は阻止される。[0023] Incidentally, the pushbutton 13 pressed in engineered or condition to be locked in an intermediate position C that releases the press, to be the second record bar 20 is swung in conjunction with this as shown in FIG. 5 Since the hook portion 20a provided faces the rotation trajectory of the cam plate 16, the rotation of the rotation knob 14 to the "water level" is prevented.
