Description

本発明は、バーナと、バーナに付設された点火電極及びこの点火電極に高電圧を印加するイグナイタと、バーナに燃料ガスを供給するガス供給路と、ガス供給路に介設され、開度の増減によりバーナに供給される燃料ガス量を増減する電動式の流量調節弁と、イグナイタ及び流量調節弁を制御するコントローラとを備えたコンロに関する。 The present invention is provided between a burner, an ignition electrode attached to the burner, an igniter that applies a high voltage to the ignition electrode, a gas supply path for supplying fuel gas to the burner, and a gas supply path, and has an opening degree. The present invention relates to a stove equipped with an electric flow control valve that increases or decreases the amount of fuel gas supplied to the burner by increasing or decreasing, and a controller that controls an igniter and a flow control valve.

従来、この種のコンロのバーナの点火制御時は、流量調節弁の開度を、バーナに供給する燃料ガス量が所定の点火用ガス量となる開度に維持した状態でイグナイタに通電して点火するようにしている（例えば、特許文献１参照）。 Conventionally, when the ignition control of the burner of this type of stove is performed, the igniter is energized with the opening degree of the flow control valve maintained at the opening degree at which the amount of fuel gas supplied to the burner becomes a predetermined amount of ignition gas. It is designed to ignite (see, for example, Patent Document 1).

上記コンロでは、電動式の流量調節弁を用いているため、一次ガス圧が変動しても燃焼ガス量が変動しないガバナ付き比例弁を用いるガス器具と異なり、一次ガス圧の変動に伴い燃料ガス量が増減してしまう。そこで、一次ガス圧が低くても確実に点火することができるように、点火制御時の流量調節弁の開度が設定されているが、一次ガス圧が高い場合、点火制御時の燃料ガス量が多くなって点火した瞬間に大きな炎が発生し、大きな点火音も伴うことから使用者を驚かせてしまうことがある。 Since the above stove uses an electric flow control valve, the fuel gas changes as the primary gas pressure fluctuates, unlike gas appliances that use a proportional valve with a governor that does not fluctuate the amount of combustion gas even if the primary gas pressure fluctuates. The amount will increase or decrease. Therefore, the opening degree of the flow rate control valve during ignition control is set so that ignition can be reliably performed even if the primary gas pressure is low. However, when the primary gas pressure is high, the amount of fuel gas during ignition control is set. A large flame is generated at the moment of ignition due to a large amount of gas, and a loud ignition noise is also accompanied, which may surprise the user.

本発明は、以上の点に鑑み、一次ガス圧が変動する場合にも使用者を驚かすことなく、安定した点火性能が得られるコンロを提供することをその課題としている。 In view of the above points, it is an object of the present invention to provide a stove that can obtain stable ignition performance without astonishing the user even when the primary gas pressure fluctuates.

上記課題を解決するために、本発明は、第１に、バーナと、バーナに付設された点火電極及びこの点火電極に高電圧を印加するイグナイタと、バーナに燃料ガスを供給するガス供給路と、ガス供給路に介設され、開度の増減によりバーナに供給される燃料ガス量を増減する電動式の流量調節弁と、イグナイタ及び流量調節弁を制御するコントローラとを備え、コントローラは、バーナの点火制御時に、イグナイタへ通電させた後、バーナへ供給する燃料ガス量が徐々に増加するように流量調節弁の開度を増加させるコンロにおいて、コントローラは、バーナの点火制御時に、流量調節弁の開度を、バーナが点火しにくい条件でも点火可能な所定の燃料ガス量が得られる所定開度まで増加させると、以後、流量調節弁の開度をその所定開度に維持させることを特徴とする。 In order to solve the above problems, the present invention is, in the first burner and the igniter for applying a high voltage to the ignition electrode and the ignition electrode is attached to the burner, a gas supply passage for supplying the fuel gas to the burner , interposed in the gas supply channel, e Preparations and motorized flow control valve to increase or decrease the amount of fuel gas supplied to the burner by increasing or decreasing the degree of opening, and a controller for controlling the igniter and flow control valve, controller, In the stove that increases the opening of the flow control valve so that the amount of fuel gas supplied to the burner gradually increases after energizing the igniter during burner ignition control , the controller adjusts the flow rate during burner ignition control. When the valve opening is increased to a predetermined opening at which a predetermined amount of fuel gas that can be ignited can be obtained even under conditions where the burner is difficult to ignite, the opening of the flow control valve is subsequently maintained at the predetermined opening. It is a feature.

本発明の第１の特徴によれば、バーナの点火制御時に流量調節弁の開度を徐々に増加させるので、バーナへ供給する燃料ガス量が徐々に増加する。従って、一次ガス圧が変動する場合にもバーナに供給される燃料ガス量が点火可能な所定量に達したところでバーナに点火する。このため、従来のような大きな点火音を伴う大きな炎の発生を抑制することができ、使用者を驚かすことなく、安定した点火性能が得られる。また、本発明の第１の特徴によれば、点火後、通常の燃焼制御に移行するまでに予期せず炎が大きなってしまうことを抑制することができる。 According to the first feature of the present invention, since the opening degree of the flow rate control valve is gradually increased during ignition control of the burner, the amount of fuel gas supplied to the burner is gradually increased. Therefore, even when the primary gas pressure fluctuates, the burner is ignited when the amount of fuel gas supplied to the burner reaches a predetermined amount that can be ignited. Therefore, it is possible to suppress the generation of a large flame accompanied by a large ignition sound as in the conventional case, and stable ignition performance can be obtained without astonishing the user. Further, according to the first feature of the present invention, it is possible to prevent the flame from unexpectedly becoming large after ignition and before shifting to normal combustion control.

また、上記課題を解決するために、本発明は、第２に、バーナと、バーナに付設された点火電極及びこの点火電極に高電圧を印加するイグナイタと、バーナに燃料ガスを供給するガス供給路と、ガス供給路に介設され、開度の増減によりバーナに供給される燃料ガス量を増減する電動式の流量調節弁と、イグナイタ及び流量調節弁を制御するコントローラとを備え、コントローラは、バーナの点火制御時に、イグナイタへ通電させた後、バーナへ供給する燃料ガス量が徐々に増加するように流量調節弁の開度を増加させるコンロにおいて、コントローラは、バーナの点火制御時に、流量調節弁の開度を、バーナが安定して燃焼可能な下限の燃料ガス量に対応する開度から増加させることを特徴とする。 In order to solve the above problems, the present onset Ming, the second burner and a gas supply and an igniter for applying a high voltage to the ignition electrode and the ignition electrode is attached to the burner, the fuel gas to the burner A controller equipped with an electric flow control valve that is installed in the supply path and the gas supply path to increase or decrease the amount of fuel gas supplied to the burner by increasing or decreasing the opening, and a controller that controls the igniter and the flow control valve. In the stove, which increases the opening degree of the flow control valve so that the amount of fuel gas supplied to the burner gradually increases after energizing the igniter during the ignition control of the burner, the controller controls the ignition of the burner. the opening of the flow regulating valve, the burner is characterized by increasing the opening degree corresponding to the amount of fuel gas of stably combustible limit.

本発明の第２の特徴によれば、バーナの点火制御時に流量調節弁の開度を徐々に増加させるので、バーナへ供給する燃料ガスが徐々に増加する。従って、一次ガス圧が変動する場合にもバーナに供給される燃料ガス量が点火可能な所定量に達したところでバーナに点火する。このため、従来のような大きな点火音を伴う大きな炎の発生を抑制することができ、使用者を驚かすことなく、安定した点火性能が得られる。また、本発明の第２の特徴によれば、流量調節弁を全閉状態から徐々に開けるときよりも早く点火させることができ、点火操作からバーナ点火までのタイムラグを小さくすることが可能となる。 According to the second feature of the present invention , since the opening degree of the flow rate control valve is gradually increased during ignition control of the burner, the fuel gas supplied to the burner is gradually increased. Therefore, even when the primary gas pressure fluctuates, the burner is ignited when the amount of fuel gas supplied to the burner reaches a predetermined amount that can be ignited. Therefore, it is possible to suppress the generation of a large flame accompanied by a large ignition sound as in the conventional case, and stable ignition performance can be obtained without astonishing the user. Further, according to the second feature of the present invention, the flow control valve can be ignited earlier than when the flow control valve is gradually opened from the fully closed state, and the time lag from the ignition operation to the burner ignition can be reduced. ..

図１に示したコンロ１は、図示省略したシステムキッチンに組み込まれるビルトイン式のものである。コンロ１は、システムキッチンのカウンタトップに開設した開口に落とし込むようにして設置されるコンロ本体１１と、コンロ本体１１の上面を覆うようにしてカウンタトップ上に載置される天板１２と、天板１２上に露出する、前側左の＃１と前側右の＃２と後側中央の＃３との計３個のバーナ１３と、コンロ本体１１内に組み込まれたグリル１４とを備えている。バーナ１３は、天板１２上にバーナ１３を囲うように載置される五徳２の上に載置する鍋等の被調理物（図示なし）を加熱する。 The stove 1 shown in FIG. 1 is a built-in type that is incorporated in a system kitchen (not shown). The stove 1 includes a stove body 11 that is installed so as to drop into an opening opened in the counter top of the system kitchen, a top plate 12 that is placed on the counter top so as to cover the upper surface of the stove body 11, and a ceiling. It is equipped with a total of three burners 13 exposed on the plate 12, # 1 on the front left side, # 2 on the front side right side, and # 3 on the rear side center, and a grill 14 incorporated in the stove body 11. .. The burner 13 heats an object to be cooked (not shown) such as a pot placed on the trivet 2 placed on the top plate 12 so as to surround the burner 13.

図２に示したように、コンロ１用のガス供給路３は、図１に示した＃１〜＃３の３個のバーナ１３と、グリル１４に設けられた、グリル１４内の被調理物を加熱する＃４のバーナ１３に燃料ガスを供給する。ガス供給路３の上流側に元弁４が介設され、また、ガス供給路３は、元弁４の下流側で４本の分岐路３ａに分岐され、各分岐路３ａが４個のバーナ１３の各１個に接続されている。各分岐路３ａには、電磁安全弁５及び電動式の流量調節弁６が介設されている。流量調節弁６は、電磁安全弁５よりも分岐路３ａの下流側に配置されている。各流量調節弁６は、モータＭにより駆動されて開度が調節される電動式のものである。流量調節弁６の弁体の開度の増減によって、分岐路３ａを通じてバーナ１３に供給される燃料ガス量が増減される。流量調節弁６としては、モータＭの回動により送りねじ機構を介して軸方向に進退するニードル弁体を有するものや、モータＭの回動により回動する円板状の回動弁体を有するものを用いることができる。 As shown in FIG. 2, the gas supply path 3 for the stove 1 includes the three burners 13 of # 1 to # 3 shown in FIG. 1 and the object to be cooked in the grill 14 provided on the grill 14. The fuel gas is supplied to the burner 13 of # 4 which heats. A main valve 4 is provided on the upstream side of the gas supply path 3, and the gas supply path 3 is branched into four branch paths 3a on the downstream side of the main valve 4, and each branch path 3a has four burners. It is connected to each one of 13. An electromagnetic safety valve 5 and an electric flow rate control valve 6 are interposed in each branch path 3a. The flow rate control valve 6 is arranged on the downstream side of the branch path 3a with respect to the electromagnetic safety valve 5. Each flow rate control valve 6 is an electric type that is driven by a motor M to adjust the opening degree. The amount of fuel gas supplied to the burner 13 through the branch path 3a is increased or decreased by increasing or decreasing the opening degree of the valve body of the flow rate control valve 6. The flow control valve 6 includes a needle valve body that moves forward and backward in the axial direction via a feed screw mechanism due to the rotation of the motor M, and a disk-shaped rotary valve body that rotates due to the rotation of the motor M. What you have can be used.

また、各バーナ１３には、点火電極７が付設され、図示省略した火炎検知のための熱電対も付設されている。さらに、コンロ１には、＃１〜＃３のバーナ１３に付設された点火電極７に同時に高電圧を印加するイグナイタ８１と、＃４のバーナ１３に付設された点火電極７に高電圧を印加するイグナイタ８２とが設けられている。コンロ１では、元弁４、電磁安全弁５、流量調節弁６のモータＭ及びイグナイタ８１，８２がコントローラＣにより制御される。コントローラＣには、例えばマイクロコンピュータ等が適用可能である。 Further, each burner 13 is provided with an ignition electrode 7, and a thermocouple for flame detection (not shown) is also attached. Further, on the stove 1, a high voltage is applied to the igniter 81 that simultaneously applies a high voltage to the ignition electrodes 7 attached to the burners 13 of # 1 to # 3 and the ignition electrode 7 attached to the burners 13 of # 4. An igniter 82 is provided. In the stove 1, the motor M of the main valve 4, the electromagnetic safety valve 5, the flow rate control valve 6 and the igniters 81 and 82 are controlled by the controller C. For example, a microcomputer or the like can be applied to the controller C.

また、図１に示したように、コンロ本体１１の前面パネル１１ａには、電源スイッチ９と、バーナ１３の＃１〜＃４の各１個に対して１個ずつの火力調節摘み兼用の点消火ボタン１００（＃１〜＃４）とが設けられている。各点消火ボタン１００は、プッシュプッシュ式であり、前面パネル１１ａに没入した消火位置から使用者が押し操作することによって没入状態が解除され、前面パネル１１ａの前方に突出し、燃焼位置となる。この燃焼位置では、点消火ボタン１００は回動可能であり、点消火ボタン１００の回動操作によって大火〜小火の範囲内での火力調節が可能である。点消火ボタン１００の押し操作及び回動操作の両操作は、図２に示した操作検知スイッチＤによって検知される。操作検知スイッチＤが出力する検知信号はコントローラＣに入力される。 Further, as shown in FIG. 1, on the front panel 11a of the stove body 11, one point for each of the power switch 9 and each of # 1 to # 4 of the burner 13 is also used as a thermal power adjustment knob. Fire extinguishing buttons 100 (# 1 to # 4) are provided. Each point fire extinguishing button 100 is a push-push type, and when the user pushes the fire extinguishing position immersed in the front panel 11a, the immersion state is released, and the fire extinguishing button 100 projects to the front of the front panel 11a to reach the combustion position. At this combustion position, the point fire extinguishing button 100 is rotatable, and the thermal power can be adjusted within the range of large fire to small fire by rotating the point fire extinguishing button 100. Both the pressing operation and the rotating operation of the point fire extinguishing button 100 are detected by the operation detection switch D shown in FIG. The detection signal output by the operation detection switch D is input to the controller C.

電源スイッチ９がＯＮにされた時、ＯＮ信号がコントローラＣに入力され、コンロ１は作動を開始する。使用者が消火位置に存する点消火ボタン１００を押して点火操作が行われると、操作検知スイッチＤから出力される検知信号がコントローラＣに入力されてコントローラＣはバーナ１３の点火制御を行う。この点火制御では、イグナイタ８１へ通電させて点火電極７に高電圧を印加し、点火電極７に連続してスパークを発生させる。尚、グリル１４用の点消火ボタン１００が押し操作されたときはイグナイタ８２へ通電させる。次いで、コントローラＣは、電磁安全弁５へ開信号を出力し、電磁安全弁５を開弁させる。尚、いずれのバーナ１３も燃焼していない状態でいずれかのバーナ１３の点火制御が行われるときは、元弁４も開弁させる。この後、コントローラＣは、図３に示したように、バーナ１３へ供給される燃料ガス量が徐々に増加するように、流量調節弁６の開度を徐々に増加させる。 When the power switch 9 is turned on, an ON signal is input to the controller C, and the stove 1 starts operating. When the user presses the point fire extinguishing button 100 in the fire extinguishing position to perform the ignition operation, the detection signal output from the operation detection switch D is input to the controller C, and the controller C controls the ignition of the burner 13. In this ignition control, the igniter 81 is energized and a high voltage is applied to the ignition electrode 7, and sparks are continuously generated in the ignition electrode 7. When the point fire extinguishing button 100 for the grill 14 is pressed, the igniter 82 is energized. Next, the controller C outputs an open signal to the electromagnetic safety valve 5 to open the electromagnetic safety valve 5. When the ignition control of any of the burners 13 is performed while none of the burners 13 is burning, the main valve 4 is also opened. After that, as shown in FIG. 3, the controller C gradually increases the opening degree of the flow rate control valve 6 so that the amount of fuel gas supplied to the burner 13 gradually increases.

このように、コントローラＣによるバーナ１３の点火制御では、バーナ１３の点火制御時に流量調節弁６の開度を徐々に増加させるので、バーナ１３へ供給する燃料ガス量が徐々に増加する。従って、一次ガス圧が変動する場合にもバーナ１３に供給される燃料ガス量が点火可能な所定量に達したところでバーナ１３に点火する。このため、従来のような大きな点火音を伴う大きな炎の発生を抑制することができ、使用者を驚かすことなく、安定した点火性能が得られる。この場合、流量調節弁６の開度の増加は、開弁から一定の割合とすることが望ましい。尚、点火により上記熱電対が加熱されてその起電圧が所定レベルに上昇したところで上記点火制御は終了し、バーナ１３の火力を点消火ボタン１００の回動操作に応じて調節する通常の燃焼制御に移行する。 As described above, in the ignition control of the burner 13 by the controller C, the opening degree of the flow rate control valve 6 is gradually increased during the ignition control of the burner 13, so that the amount of fuel gas supplied to the burner 13 is gradually increased. Therefore, even when the primary gas pressure fluctuates, the burner 13 is ignited when the amount of fuel gas supplied to the burner 13 reaches a predetermined amount that can be ignited. Therefore, it is possible to suppress the generation of a large flame accompanied by a large ignition sound as in the conventional case, and stable ignition performance can be obtained without astonishing the user. In this case, it is desirable that the opening degree of the flow rate control valve 6 is increased at a constant rate from the opening of the valve. When the thermocouple is heated by ignition and its electromotive voltage rises to a predetermined level, the ignition control ends, and the thermal power of the burner 13 is adjusted according to the rotation operation of the point fire extinguishing button 100. Move to.

また、コントローラＣは、バーナ１３の点火制御時に、流量調節弁６の開度を、バーナ１３が点火しにくい条件でも点火可能な所定の燃料ガス量が得られる所定開度θＨまで増加させると、以後、流量調節弁６の開度を所定開度θＨに維持させるようにプログラムされている。このため、点火後、通常の燃焼制御に移行するまでに予期せずに炎が大きくなってしまうことを抑制することができる。尚、点火しにくい条件としては、例えば、システムキッチンのレンジフードを作動させる等によりコンロ１の周辺に上昇気流等の空気の移動が起こり、風が発生した場合、風圧によってバーナ１３の炎孔から噴出する燃料ガスに外乱が生ずる等が例示される。 The controller C, upon ignition control of the burner 13, the opening degree of the flow rate control valve 6, when a predetermined amount of the fuel gas can be ignited increases to a predetermined opening degree theta H obtained even under conditions where the burner 13 is not easily ignited hereafter, and is programmed to maintain the degree of opening of the flow control valve 6 to a predetermined angle theta H. Therefore, it is possible to prevent the flame from growing unexpectedly after ignition and before shifting to normal combustion control. As a condition that makes it difficult to ignite, for example, when air such as an updraft occurs around the stove 1 by operating the range hood of the system kitchen and wind is generated, the wind pressure causes the flame hole of the burner 13 to move. An example is that a disturbance occurs in the ejected fuel gas.

さらに、コントローラＣは、バーナ１３の点火制御時に、流量調節弁６の開度を、バーナ１３が点火しにくい条件でも点火可能な所定の燃料ガス量が得られる所定開度θ Ｈ に替え、バーナ１３が安定して燃焼可能な下限の燃料ガス量に対応する開度θＬから増加させるようにプログラムされる。このため、流量調節弁６を全閉状態から徐々に開けるときよりも早く点火させることができ、点火操作からバーナ１３の点火までのタイムラグを小さくすることが可能となる。尚、流量調節弁６の上記開度については、θＨ＞θＬの関係にあり、上記「バーナ１３が安定して燃焼可能な下限の燃料ガス量」とは、燃料ガスに上記外乱が生ずるほどではない微風によって消火しない程度の燃料ガスの供給量を意味する。また、開度θＨ，θＬの大きさは、バーナ１３の火力性能等に応じて適宜設定することができ、開度θＨ，θＬと燃料ガス量の関係は、これまでの経験値に基づいて適宜設定することができる。 Furthermore, the controller C, the ignition control of the burner 13, the opening degree of the flow rate control valve 6, also replaced to a predetermined opening degree theta H a predetermined amount of fuel gas that can ignite is obtained under the condition that the burner 13 is less likely to ignite the burner 13 is programmed to increase from opening theta L corresponding to the fuel gas amount stably combustible limit. Therefore, the flow rate control valve 6 can be ignited earlier than when it is gradually opened from the fully closed state, and the time lag from the ignition operation to the ignition of the burner 13 can be reduced. The opening degree of the flow control valve 6 has a relationship of θ H > θ L , and the above-mentioned "lower limit fuel gas amount at which the burner 13 can stably burn" means that the above-mentioned disturbance occurs in the fuel gas. It means the amount of fuel gas supplied to the extent that the fire is not extinguished by a moderate breeze. The size of the opening theta H, theta L may be appropriately set according to the thermal performance of the burner 13, the relationship between the opening theta H, theta L and the fuel gas amount, previous experience value Can be set as appropriate based on.

尚、コントローラＣによる上記点火制御は、ガス漏れ等の万一の場合を考慮して、点火操作開始から１０秒程度までの間に通常の燃焼制御に移行しないとき、点火ミスと判断するのが望ましい。点火ミスと判断した時は、コントローラＣは、電磁安全弁５を閉弁させると共に、コンロ１に設けられる、図示省略した報知機によりエラー報知を行う。また、コントローラＣによる点火制御は、一般に＃１〜＃３のバーナ１３に適用されるものであるが、グリル用である＃４のバーナ１３に対しても等しく行うことは可能である。 It should be noted that the ignition control by the controller C is determined to be an ignition error when the ignition control does not shift to the normal combustion control within about 10 seconds from the start of the ignition operation in consideration of an emergency such as a gas leak. desirable. When it is determined that an ignition error has occurred, the controller C closes the electromagnetic safety valve 5 and notifies an error by an alarm provided on the stove 1 (not shown). Further, the ignition control by the controller C is generally applied to the burners 13 of # 1 to # 3, but can be equally applied to the burners 13 of # 4 for grilling.
