In this type of gas control device, when the gas burner is ignited, in order to achieve a certain firepower of the gas burner, a flameout button for implementing gas combustion as the point of ignition and flameout is set and the gas supply amount of fuel to the gas burner is adjusted. It is well known that the firepower adjustment dial can be rotated to a certain position by moving the fire-extinguishing dial by 10 times in the front-back direction (Patent Document 1). The ignition is formed into a cylindrical shape as described, and can be moved freely in the forward and backward directions. For example, the operation panel in front of the gas furnace. Furthermore, when the operating point flameout button is pressed from the valve closing position of the gas passage, the flameout button is moved to the ignition position, the gas passage is opened, and the ignition device of the gas burner is activated. If it is confirmed that the gas burner is on fire and the press-in of the click-out button is released, the click-out button will be protruded from the operation panel to the valve opening position. At the valve opening position, the ring-shaped fire adjustment dial around the ignition button is used to adjust the fire power of the gas burner. The fire power adjustment dial is to change the opening area of the gas passage provided in the gas passage and is linked to a gas flow adjustment device that adjusts the fuel gas flow toward the gas burner. When the combustion of the gas burner is stopped, if the flameout button operated at the valve opening position is pushed in and moved to the valve closed position, the gas passage is blocked and the gas burner is extinguished. At this time, there is a reset device for interlocking with the ignition and pressing the sister's press-in operation to force and turn the 1232283 dial of the firepower adjustment indicator to the strong fire position. Therefore, the valve closing position of the ignition button cannot be rotated by the reset device. Power adjustment dial. Patent Literature Patent No. 2742356 (for example, description of patent application scope). 5 Therefore, it can be considered that the ignition button can be moved in accordance with the press-in operation during the ignition operation. The valve closing position protruded from the operation panel is moved to the ignition position through the valve opening position, and it is set in conjunction with the ignition operation of the ignition button at this point. In the press-in operation, the firepower adjustment dial is forcibly turned, so that the amount of fuel gas supplied to the gas burner becomes a certain amount. However, if the forced rotation is performed between the point when the flameout button 10 is moved from the valve closing position to the valve opening position, it must be ensured that the turning power adjustment dial can be turned to a certain position between the valve closing position and the valve opening position. The moving distance of the dot-off button. As a result, the forward and backward movement distance of the dot-off button at the time of ignition operation becomes longer, which causes a problem of inconvenience in use. 15 Therefore, in view of the above-mentioned facts, the present invention aims to provide a method for forcibly turning the power adjustment dial even if the push-in button of the fire-off button is pressed during the ignition operation. Easy to use gas control device. [Explanation]] In order to solve the above-mentioned problem, the gas control device of the present invention has a point-extinguish button that can move freely in the front-rear direction, and at the position in the front-rear direction, there is a valve-opening position that keeps the gas passage to the gas burner open, The position of the valve to close the gas passage and the ignition position of the ignition device of the gas burner are activated. Around the flameout button at this point, a ring-shaped firepower that can adjust the gas supply to the gas burner and can rotate freely is provided. The dial is characterized in that the aforementioned secret fire button can be pressed through the ignition during the ignition operation, and the aforementioned _position㈣ to the front fire position_ can be passed through the prominent position, and a forced rotation device is provided. Rotating device with _ the previous point of extinction according to the pressure of Nayu Mai 4 and turn the front j fire adjustment dial 'to make the fuel gas supply to the gas burner -U' X 'the miscellaneous fire button From the aforementioned position to the aforementioned ignition position, the forced rotation of the firepower adjustment can be performed by the forced rotation device. 10 According to the present invention, if the fire button is pressed into the operating point from the closed valve position for the ignition operation, the gas passage is opened and the fuel gas flows into the gas burner. In addition, if the flame is reached to the valve opening position alone, the firepower adjustment dial is started to rotate by forced rotation, and if it reaches the ignition position, the ignition action of the gas burner is implemented. At this time, when the ignition position is reached, the rotation of the firepower 15 adjustment dial toward a certain position has ended. If it is confirmed that the gas burner is ignited and the press-in of the ignition button is released, the ignition button will return to the front side and reach the valve opening position. If the power adjustment dial is turned at the valve opening position, the gas flow rate of the fuel gas supplied to the gas burner can be increased or decreased to adjust the fire power of the gas burner. 20 Here, in the gas passage, an electromagnetic safety valve is generally provided, and in order to open the electromagnetic safety valve, it is necessary to move the point of fire button between the valve opening position and the ignition position when the operating point flameout button is pressed. The distance is set to be longer. At this time, in the present invention, since the moving distance of the flameout button 5 is set to a longer valve opening position and the ignition position for opening the electromagnetic safety valve, the space between the valve opening position and the ignition position is used to force the turning of the power adjustment dial. Therefore, for the required moving distance of the flameout button between the closed position and the valve open position with a short moving distance, compared with the increase of the forced turning of the power adjustment dial, the short ignition button can be used. The distance is moved forward and backward, so the operation is good, and it is easy to use. In addition, since the engagement of the forced rotation device can be released by returning from the ignition position to the valve-opening position, there is no need to additionally provide a mechanism that does not interfere with the power adjustment dial in the valve-opening position and does not need to increase the number of parts. '10 15… Column-turning system is composed of a cry-out film and a cam groove' and the money-out film is set at a point that can be operated by pressing the fire button to move it in the front-to-rear direction through the fire adjustment dial. On the push rod, and the cam groove is provided on the inner peripheral surface of the thermal power adjustment dial. In addition, the aforementioned protruding piece follows: the aforementioned point fire button—moves from the point ㈣ toward the point button to engage with the cam V groove, and if the pressing of the point flameout button is released and returns to the on from the ignition position Valve position, the protruding piece and the cam groove will: re-engage, so it will not increase the number of parts, will not damage the operability of the firepower adjustment dial in the open position, and will not affect the cooker ’s operating feeling Cause bad effects. Furthermore, if a convex portion is provided on the inner side of the thermal adjustment dial with the cam groove formed therein, the thermal adjustment dial is rotated at the valve opening position to abut the protruding piece, so as to limit the convex portion of the thermal adjustment dial rotation range. 'There is no need to separately set a standard stop to limit the rotation of the power adjustment dial, which can reduce the number of parts and reduce costs. In addition, a locking position may also be provided, and the locking position is at the valve closing position of 20 1232283. When the thermal power dial is turned beyond the rotation range to a certain position, the front surface of the convex portion and the protrusion are made.

10操作性，不會對於烹調者之轉動操作感造成不好的影響。 又，由於藉由解除點熄火按鈕5之壓入時之點熄火按鈕5之 回位來解除突起片51b與凸輪溝72c之卡合，故也無須另外 設置在開閥位置時強制旋轉裝置51b不會干擾火力調節梯 度盤7之凸輪溝72C的機構，因此不會增加零件數。 15 為限制火力調節標度盤7之旋轉範圍，在形成有標度盤 構件72之凸輪溝72c處，形成相互對置之兩個凸部。旋轉體 61係配置成若轉動火力調節標度盤7,使其反時針方向轉動 到各突起片51b抵接該凸部為止，則第2、第3及第4之各長 溝62b，62C，62d分別與第2、第3及第4之各連通路15b，15c， 20 15d致朝瓦斯流出部16之瓦斯量變成最大。另一方面， 若順時針方向轉動到各突起片51b抵接該凸部72d為止，則 僅第1長曰溝62a與第i連通路15a 一致，可使朝瓦斯流出部κ 之瓦斯量變成最小。由此，在開閥位置時，火力調節標度 盤7僅在使朝瓦斯流出部16之瓦斯流量為最小且瓦斯燃燒 !232283 器23之火力為小之小火力與使瓦斯流量為最大且瓦斯燃燒 器23之火力為強之強火力之間的火力調節範圍内旋轉自 如。由此，為限制火力調節標度盤7之旋轉範圍，無須個別 地設置擋止器等，可減少零件數，且可具有較低成本。 5 如第3圖所示，在點熄火按鈕5之閉閥位置時，突起片 51b位於形成標度盤構件72之凸輪溝72c處的前方側。此 時，在閉閥位置時，可使火力調節標度盤7反時針方向轉動 超過火力調節範圍。在該位置，突起片51b與凸部72d對置。 由此，即使壓入操作點熄火按鈕5，突起片51b亦會抵接凸 10部72d之前面板24前側之面，形成點熄火按鈕5不能由閉閥 位置移動至點火位置之鎖固位置，且形成安全鎖。此時， 在標度盤構件72外周面設有突出部E(參閱第8圖），只要該 突出部E抵接設置於第1部份lla之制止器（未圖示），就可到 達鎖固位置。 15 請參閱第6圖及第14圖，在標度盤構件72之前方側内周 面，在同一圓周方向上以一定間隔形成第1、第2及第3之各 四部72e，72f，72g。在點熄火按紐5之後方側端部，形成 有半徑方向之孔5b，且在該孔5b中，以彈簧C1賦與向標度 盤構件72内周面勢能的狀態下收納圓筒形狀之掣子構件 20 C。而且，在開閥位置時，若轉動火力調節標度盤7到達一 定位置，則掣子構件會嵌合凹部72e，72f，72g並發出卡答 聲。 接著，說明本發明瓦斯控制裝置1之動作。若由在第2 圖所示閉閥位置壓入操作點熄火按鈕5，則經由推桿51推壓 17 !232283 操作桿4至後方並開啟主閥，且一旦到達第3圖所示之開閥 位置，則突起片51b與凸輪溝72c卡合。在到達將閥體32按 壓至吸附片側之點火位置之前，火力調節標度盤7一直轉動 到中火位置為止。此時，旋轉體61可經由齒輪G轉動，且在 5該位置，第1，第2及第3之各長溝62a，62b，62c分別與第1、 第2及第3之各連通路15a，15b，15c—致，使瓦斯燃燒器23 之火力為中之瓦斯流量之燃料瓦斯朝瓦斯流出部16流入 (茶閱第5圖）。又，掣子構件c嵌合於第2凹部72f(參閱第14 圖）中。 1〇 若到達點火位置，則藉放電器實施瓦斯燃燒器23之點 火操作。而且，如設於瓦斯燃燒器23附近之火焰檢出元件 (未圖示）檢出瓦斯燃燒器23之火焰，則藉來自控制裝置之信 號激磁以保持電磁閥3開啟。若確認瓦斯燃燒器23已著火而 要解除點熄火按鈕5之壓入，則點熄火按鈕5藉心形凸輪機 15構導引到達在第3圖所示之開閥位置。 若為增大瓦斯燃燒器23之火力，由中火位置反時針方 向轉動，使掣子構件C嵌合第3凹部72g，則在凸部72d抵接 各突起片51b。此時，第2、第3及第4之各長溝62b，62c， 62d分別與第2、第3及第4之各連通路15b，15c，15d 一致， 2〇使瓦斯燃燒器23火力為強之瓦斯流量之燃料瓦斯朝瓦斯流 出部16流入(參閱第15圖）。 另一方面，若為由中火減少瓦斯燃燒器23之火力，順 時針方向轉動火力調節標度盤7,使掣子構件C嵌合第1凹部 72e ’則第1及第2之各長溝62a，62b分別與第1及第2之各連 Ϊ232283 通路…，⑼―致，使瓦斯燃燒器23火力為弱之瓦斯流量 士 i’、料瓦斯朝瓦斯流出部16流入(參閱第關卜接著，若順 了、十方向轉動火力調節標度盤7直到各突起片训抵接凸部 5 則第1長溝62a僅與第1連通路15a-致，使瓦斯燃燒器 23火力為小之最小瓦斯流量之燃料瓦斯朝瓦斯流出部I6流 入(參閱第17圖）。 若H咸瓦斯燃燒為23時，由開閥位置向後方側壓入 知作點媳火按紐5，則心形凸輪機構重置，且點媳火按钮5 笑彈簧17之賦勢力後退到第2@所示關位置。此時，解除 10推才干51推壓之操作桿4受彈菁34之賦勢力向前方側移動，使 主閥關閉。若主閥關閉，則朝瓦斯燃燒器23之燃料瓦斯之 仏給停止而可熄火。若藉火焰檢出元件控制裝置辨識火焰 已媳滅’則可關閉電磁安全閥3。 此外，在本實施形態中，雖在反射構件73形成反射層， 15但並不限於此，譬如，也可在標度盤構件72内側形成反射 層。又，在本實施形態中，雖說明關於在中火位置點火之 情形，但不限於此，譬如，也可形成凸輪溝而可在強火位 置點火操作。再者，在本實施形態中，雖說明關於在瓦斯 爐2之前面板24設置點熄火按紐5及火力調節標度盤7之情 20形’但也可在烤箱，烤架等其他瓦斯烹調器中使用具有點 媳火按紐及火力調節標度盤之本發明瓦斯控制裝置，譬 如’具有點媳火按姐及火力調節標度盤之本發明瓦斯控置 裝置也適用在覆蓋爐具本體之面板設有操作板之瓦斯爐。 依據以上說明本發明之瓦斯控制裝置，即使藉點火操 1232283 作時之點熄火按鈕之壓入操作來強制轉動火力調節標度 盤，亦可達成點熄火按鈕之前後方向移動距離短，且使用 上方便之效果。 L圖式簡單說明3 5 第1圖係組裝入本發明瓦斯控制之瓦斯爐料之立體圖。 第2圖係在閉閥位置之本發明瓦斯控制裝置之截面圖。 第3圖係在點火位置之本發明瓦斯控制裝置之截面圖。 第4圖係在開閥位置之本發明瓦斯控制裝置之截面圖。 第5圖係說明轉體之立體圖。 10 第6圖係說明點熄火按鈕與火力調節標度盤構成之分 解立體圖。 第7圖係說明相對於火力調節標度盤之光源位置之圖。 第8圖係說明在熄火位置之強制旋轉裝置之圖。 第9圖係說明在熄火位置之強制旋轉裝置之圖。 15 第10圖係說明在點火位置之強制旋轉裝置之圖。 第11圖係說明在點火位置之強制旋轉裝置之圖。 第12圖係說明由強制旋轉裝置強制的轉動火力調節標 度盤之圖。 第13(a)及(b)圖係說明點熄火按鈕之鎖固位置之圖。 20 第14圖係說明轉動流量調節標度盤到達中火位置時發 出卡答聲之圖。 第15 (a)及(b)圖係說明轉動流量調節標度盤到達強火 位置之圖。 第16(a)及(b)圖係說明轉動流量調節標度盤到達弱火 20 1232283 位置之圖。 第17(a)及(b)圖係說明轉動流量調節標度盤到達小火 位置之圖。 【圖式之主要元件代表符號表】 1···瓦斯控制裝置 2…瓦斯爐 3···電磁安全閥 4…操作桿 5···點媳火按鈕 5a…段部 5b…孔 6···流量調節閥 7···火力調節標度盤 11a···閥殼第1部份 lib···閥殼第2部份 12a···第1内部通路 12b···第2内部通路 13…瓦斯流入部 14…瓦斯流出口 15a···第1連通路 15b···第2連通路 15c···第3連通路 15d···第4連通路 16…瓦斯流出部 17…彈簧 21…爐具本體 22···面板 23…瓦斯燃燒器 24…前面板 25…烤架 31…磁電箱 32…第1閥體 33…彈簧 34…閥座構件 34a…密封材 42…第2閥體 43…閥座 44…彈簧 51…推桿 51a···導引部 51b···突起片 52…心形凸輪機構 61…旋轉體 62a···第1長溝C 5 / $ See Fig. 1, which is the gas control device of the present invention.

On the outer peripheral surface of the second part Ub, four first, second, third, and fourth communication paths 15a, 15b, 15c, and each communication path 15a are provided with a certain interval. 15b, 15c, and 15d communicate with the gas outflow portion 16 connected to the upper part of the second wound lib and the second internal passage ιπ. In addition, the fuel gas produced by 4 to 16% of the fuel gas is supplied to the gas burners 23 and the gas nozzles (not shown) that inject fuel gas at the ceramic tube = burner mixing pipes. 2 The internal passage 12b is provided with a flow regulating valve 6 to regulate the gas supply amount of fuel gas to the gas nozzle. % Refer to FIG. 2 and FIG. 5, the flow regulating valve 6 has a cylindrically-shaped rotating body η that is rotatably inserted: the second inner channel 12 b. On the outer peripheral surface of the rotating body η, there are four long grooves corresponding to the ith, second, third, and fourth communication paths ⑸, 15 b ′ 15c ′ I5d in the circumferential direction. 62a, will '62C, 62d. At this time, the widths and blades of the respective long grooves 62a, 62b, 62c, and 62d are consistent with the diameters of the communication paths 15a, bb, 15c, and 15d, and when the circle ^ Wilt pg is formed, the formation passes through the communication paths ⑸, ⑽, 15 c i5d toward the gas outflow portion 16 and a certain amount of four throttle orifices 63a, 03b, 03c, 63d in the gas' claws of the fuel gas flowing in, throttle members 63, each communication path 15a, 15b, 15e, I5d- Consistent, and installed on the second part of the lib. Furthermore, the rotating body 61 is rotated so that each of the long grooves 62a, 62b, 62c, and 62d 1232283 matches the communication paths 15a, 15b, 15c, and 15d, and the gas flow rate of the fuel gas flowing into the gas outflow portion 16 can be adjusted. The adjustment of the rotation angle of the rotating body 61 is performed by a ring-shaped fire power adjustment dial 7 provided around the light-off button 5. 5 However, the flameout button 5 and the power adjustment dial 7 are arranged on the front panel 24 of the stove body 21, and the lightout button 5 will protrude from the power adjustment dial 7 in the valve opening position, which is easy to attach, for example, in the Dirt or dust such as spilled soup or soot from the grill 25 during cooking. In addition, when the outflow of soup is generated during cooking, the boiling juice may adhere to the flameout button 5 and 10 enters the gas furnace 2 along the flameout button 5 to adversely affect the electrical board or switch. . Referring to FIG. 2 and FIG. 6, in the present embodiment, while the flameout button 5 and the front end face of the fire adjustment dial 7 are made as a rough side, the outer periphery of the fireout button 5 and the fire adjustment scale are clicked at the same time. There is a space s between the inner peripheral surface of the disk 7 and the outer peripheral surface of the button 5 which can be turned off by the fire adjustment dial 7 and the front panel 24. When the valve is closed, the ignition button 5 and the fire adjustment dial 7 are integrally formed and protrude forward from the front panel 24. When the flame-out operation point flameout button 5 is moved to the valve opening position, the power adjustment gradient plate 7 can be moved to the rear side accordingly. At this time, the firepower adjustment dial 7 can operate the firepower adjustment dial 7 to adjust the length of the firepower of the gas burner 23 according to f I, and is protruded from the front panel 24. As a result, the light-off button 5 and the power adjustment dial 7 are pressed into the rear side of the recloser f, and the outer surface of the light-off button 5 is often covered by the power adjustment scale 7. Therefore, even if the overflow occurs during cooking, Soup and boiling juice are not easy. 12 1232283 Falling on the fire adjustment dial 7, and even if the juice falls on the fire adjustment dial 7, the juice just falls down along its surroundings, and the juice will not intrude into the outer periphery of the fire button 5. . Therefore, it is possible to prevent the boiled juice from entering the gas furnace 2 by pressing the stop button 5. In addition, because the space s is provided, the town prevents the adhesion of dust between the light-off button 5 5 and the power adjustment dial 7, which prevents the power-adjustment dial 7 from being pressed in by the light-off button 5. Smooth forced rotation. The firepower adjusting dial 7 includes a knob member 71 that moves and rotates at the same time as the fire button 5 is moved forward and backward, and a dial member 72 that rotates the rotating body 61. The end portion of the first internal passage 11A side of the dial member 72 is milled at a constant pitch, and the milled tooth portion 72a is engaged with the gear G fitted to the end of the rotating body 61 protruding from the second portion lib. Thereby, the rotating body 61 can be rotated in synchronization with the rotation operation of the dial member 72. Further, at the other end portion of the dial member 72, recessed portions 721) extending outward in the radial direction are provided at two locations facing each other. 15 Cover point turn-off button 5 The knob member 71 on the outer peripheral surface is transparent and made of resin, and at the end of the first internal passage Ua side, protruding pieces 71a extending on the side of the first passage 71a are disposed opposite to each other. . Each of the protruding pieces 71 a is slidably engaged with each of the recessed portions 72 b to assemble the knob member η and the dial mechanism 72. A reflective member 73 is mounted on the side of the knob member such that the inner shape of the knob 20 member 71 is substantially the same. On the outer surface of the reflective member 73, a reflective layer can be formed by applying an inscription. In addition, the reflecting member 73 is cut into a collar portion formed on the outer peripheral surface of the point fire button 5 and a collar portion 71b formed on the inner peripheral surface of the knob member 71 at the same time. On the 73rd floor of the collar part, the bullet * 44 gives the diffusive member a potential energy of 13 1232283 toward the front side. Therefore, if the rotation knowing member 71 pushes against the point-extinguishing button 5 by the force imparted by the potential energy by the spring 74, and repeatedly enters the operating point to fire the button 5, the rotation member η can move to the rear side accordingly, and if When the knob member 71 is turned in the valve opening position, the dial member ^ can be rotated through the recessed portion engaged with the protruding piece 71a. On the other hand, in the closed valve position of the aforementioned point, the firepower adjustment dial 7 can be exposed at the point! The fire button 5 moves independently in the direction of the outer peripheral surface. At this time, as long as the knob member 7 is moved at the valve closing position, the outer peripheral surface of the flame can be exposed, so that the dust attached to the outer peripheral surface can be cleaned. In addition, even if the 10 holding power adjustment dial 7 is pressed in, the flameout button 5 will not move, and there will be no damage to the forced rotation device described later. Furthermore, since the reflecting member 73 is provided, even if dust or dirt adheres to the outer peripheral surface of the light-off button 5, the reflecting member 73 can be covered by the reflecting member 73. Please refer to FIG. 7 'On the inside of the front panel 24, a light source E such as a light emitting diode (LED) irradiated with light by a transparent knob structure 15 on the direction reflecting member 73 is provided, and the fire button 5 is turned on. At the valve position, light is irradiated by the light source, so that the knob member 71 is illuminated. Thereby, the operation state of the gas furnace 2 can be visually confirmed. At this time, a chamfered portion C is formed on the front side edge portion of the aforementioned firepower adjustment dial 7, and when the dial member 71 is irradiated with light from the light source E, the chamfered portion c 20 is formed annularly. Shiny. Further, a convex portion 73b (see FIG. 6) extending in the longitudinal direction is formed on the surface of the reflecting member 73, and the convex portion 73b can be accommodated in an accommodating portion 71c provided in the longitudinal direction of the knob portion 71. Since the fire position of the gas burner displayed on the front panel 24 coincides with the convex portion 73b, it constitutes an index portion that can be used as a fire index of the gas burner 23. In addition, since the indicator part does not illuminate even if the light from source 1232283 is irradiated, there is a surface effect around the relatively bright, so the cook can easily identify the consistency of the fire position and the indicator. Referring to FIGS. 8 to 12, a cam groove 72 c is formed on the inner peripheral surface on the rear side of the dial member 72, and the outer peripheral surface of the push rod 51 in the dial member 72 is moved in the front-rear direction. The two protruding pieces 5lb (see FIG. 6) paired with the cam groove 72, and the cam groove 72c and the protruding piece 51b constitute a forced rotation device. At this time, the height of the wall surface of the cam groove 72c becomes lower from one side to the other side as the forced operation of the fire button 5 is turned on. Further, if it is the ignition of the gas burner 23, the valve closing position is pressed into the operating point and the flame 5 is pressed to reach the valve opening position 10, the protruding piece 51b is engaged with the cam groove 72c, and the protruding piece 5ib becomes The driving section rotates the dial member 72 formed by the cam groove 72c as the driven section. When the ignition-off button 5 is reached to the ignition position, it can be turned to a position where the fuel gas that can reliably catch the fire is supplied to the gas burner 23. In this embodiment, by using the forced rotation device 51b and the cam groove 72c, the thermal power adjustment dial 7 can be forcibly turned to the intermediate fire position by the pressing operation of pressing the flame 5 and pressing. At this time, 'because of the use of a point of fire to press the 4 and 5 press operation to rotate the firepower adjustment dial 7, for example, there is no need to increase the force of the spring 17 retracted between the push rod 51 and the first part 11a , Can simplify the structure of the gas control device. In addition, the space between the valve opening position and the ignition position is set to a longer distance for the ignition of the fire safety valve 3 to open the electromagnetic safety valve 3 according to 5 for the purpose of forcibly turning the power adjustment dial 7 so that For the movement distance of the fire button 5 between the closed valve position and the valve open position with a short moving distance, the ignition can be shortened by 15 compared with the increase of the distance of the forced turning fire adjustment dial 7 1232283 Button 5 moves forward and backward in direction, so it has good operation feeling and easy to use. When in the ignition position, the discharger is activated to ignite the gas burner 23. In other words, if the pressing-in of the flameout button 5 is released, the heart-shaped cam mechanism 52 guides the bow 丨 and pushes it back slightly by the force of the spring 17 so that the flameout button 5 reaches the valve opening device 5. In the valve opening position, the engagement between the protruding piece 51b and the cam groove 72c is released, and the dial member 72 can rotate freely in a clockwise direction or a counterclockwise direction. At this time ', if the rotating body 61 is rotated to turn the fire power adjustment dial 7 clockwise, the gas flow rate can be reduced, and rotating it counterclockwise can increase the gas flow rate. Thereby, the operability of the thermal adjustment dial 7! 10 in the valve opening position is not impaired, and it will not adversely affect the cooking operation feeling of the cook. In addition, since the engagement of the protruding piece 51b and the cam groove 72c is released by releasing the return of the point-extinguishing button 5 when the point-extinguishing button 5 is pushed in, it is not necessary to separately install the forced rotation device 51b at the valve opening position. It will interfere with the mechanism of the cam groove 72C of the thermal power adjustment gradient disc 7, so it will not increase the number of parts. 15 In order to limit the range of rotation of the thermal power adjustment dial 7, two cam portions facing each other are formed at the cam groove 72c where the dial member 72 is formed. The rotating body 61 is arranged such that if the thermal power adjustment dial 7 is rotated so as to rotate counterclockwise until each protruding piece 51b abuts the convex portion, the second, third, and fourth long grooves 62b, 62C, 62d Each of the communication paths 15b, 15c, and 2015d connected to the second, third, and fourth channels causes the gas amount toward the gas outflow portion 16 to be maximized. On the other hand, if the protrusions 51b are turned clockwise until the protrusions 51b abut the convex portions 72d, only the first long groove 62a coincides with the i-th communication path 15a, and the gas amount toward the gas outflow portion κ can be minimized. . Therefore, at the valve opening position, the thermal power adjustment dial 7 only minimizes the gas flow toward the gas outflow portion 16 and burns the gas! 232283 The fire power of the device 23 is small and the gas flow is maximized and the gas The fire power of the burner 23 is free to rotate within the fire power adjustment range between the strong fire power. Therefore, in order to limit the rotation range of the thermal power adjustment dial 7, it is not necessary to separately provide a stopper or the like, the number of parts can be reduced, and the cost can be lowered. 5 As shown in FIG. 3, when the stop button 5 is closed, the protruding piece 51b is positioned on the front side of the cam groove 72c forming the dial member 72. At this time, in the valve closing position, the thermal power adjustment dial 7 can be turned counterclockwise to exceed the thermal power adjustment range. At this position, the protruding piece 51b faces the convex portion 72d. Therefore, even if the operating point fire-extinguishing button 5 is pushed in, the protruding piece 51b will abut the front face of the front panel 24 of the convex portion 72d, forming the point fire-extinguishing button 5 which cannot be moved from the valve closing position to the locked position of the ignition position, and Form a safety lock. At this time, a protruding portion E is provided on the outer peripheral surface of the dial member 72 (see FIG. 8). As long as the protruding portion E abuts a stopper (not shown) provided in the first portion 11a, the lock can be reached.固 位置。 Solid position. 15 Referring to FIGS. 6 and 14, the first, second, and third four portions 72e, 72f, and 72g are formed on the inner peripheral surface of the front side of the dial member 72 at regular intervals in the same circumferential direction. A hole 5b in the radial direction is formed at the end of the side after the ignition button 5 is pressed, and a cylindrical shape is accommodated in the hole 5b in a state where potential energy is applied to the inner peripheral surface of the dial member 72 by a spring C1. Claw member 20 C. Furthermore, when the thermal power adjustment dial 7 is turned to a certain position at the valve opening position, the latch members will fit into the recesses 72e, 72f, 72g and click. Next, the operation of the gas control device 1 according to the present invention will be described. If the operation point flameout button 5 is pressed in the valve closing position shown in FIG. 2, the 17! 232283 operation lever 4 is pushed to the rear through the push rod 51 and the main valve is opened, and once the valve opening shown in FIG. 3 is reached Position, the protruding piece 51b is engaged with the cam groove 72c. Before reaching the ignition position where the valve body 32 is pressed to the side of the adsorption sheet, the thermal power adjustment dial 7 is rotated to the intermediate fire position. At this time, the rotating body 61 can rotate through the gear G, and at the 5 position, the first, second, and third long grooves 62a, 62b, and 62c are respectively connected to the first, second, and third communication paths 15a, 15b, 15c-cause the gas of the gas burner 23 to have a medium gas flow, and the gas flows into the gas outflow portion 16 (see Figure 5 of the tea). The catch member c is fitted in the second recessed portion 72f (see FIG. 14). 10 If the ignition position is reached, the ignition operation of the gas burner 23 is performed by the discharger. Further, if a flame detection element (not shown) provided near the gas burner 23 detects the flame of the gas burner 23, the signal from the control device is excited to keep the solenoid valve 3 open. If it is confirmed that the gas burner 23 is on fire and the press-in of the flameout button 5 is to be released, the flameout button 5 is guided to the valve-opening position shown in Fig. 3 by a heart cam mechanism. In order to increase the fire power of the gas burner 23, the counter-clockwise direction is turned from the middle fire position, and the catch member C is fitted into the third concave portion 72g, and then the convex portions 72d abut each projection piece 51b. At this time, the second, third, and fourth long grooves 62b, 62c, and 62d are consistent with the second, third, and fourth communication paths 15b, 15c, and 15d, respectively, and 20 makes the gas burner 23 fire stronger. Fuel gas with a gas flow rate flows toward the gas outflow portion 16 (see FIG. 15). On the other hand, if the fire power of the gas burner 23 is reduced by the medium fire, the fire power adjustment dial 7 is turned clockwise to make the catch member C fit into the first recessed portion 72e ', then each of the first and second long grooves 62a 62b and 232283 passages of the first and second joints respectively, ..., cause the gas burner 23 to have a weak gas flow rate i ′, and the gas flows into the gas outflow portion 16 (refer to the next section, If the fire power adjustment dial 7 is turned in the ten directions, the projections abut the convex part 5, then the first long groove 62a is only connected to the first communication path 15a, so that the firepower of the gas burner 23 is the minimum gas flow. The fuel gas flows into the gas outflow section I6 (see Figure 17). If the H2 gas is burned at 23, the valve opening position is pushed to the rear side and the known fire button 5 is pressed, and the heart-shaped cam mechanism is reset. , And press the fire button 5 and the laughing force of the spring 17 retreats to the position shown at 2 @. At this time, the operation lever 4 of the 10 pushing ability 51 and the pushing of the pushing lever 4 is moved to the front side by the force of the elastic blue 34, so that The main valve is closed. If the main valve is closed, the fuel gas supply to the gas burner 23 is stopped and the Fire. If the flame detection element control device recognizes that the flame is extinguished, the electromagnetic safety valve 3 can be closed. In addition, in this embodiment, although a reflective layer is formed on the reflective member 73, 15 is not limited to this, for example, A reflective layer may also be formed inside the dial member 72. In this embodiment, the case of igniting at a moderate fire position is described, but it is not limited to this. For example, a cam groove may be formed to ignite at a high fire position. In addition, in this embodiment, although the description of the setting of the point-extinguishing button 5 and the power adjustment dial 7 on the front panel 24 of the gas furnace 2 is described, the shape can also be used in other types of gas such as an oven and a grill. The gas control device of the present invention with a light-burning button and a fire-power adjusting dial is used in a cooking device. For example, the gas control device of the present invention having a light-burning button and a fire-adjusting dial is also suitable for covering stoves. The panel of the body is equipped with a gas furnace with an operating panel. According to the gas control device of the present invention described above, even if the pressing operation of the flameout button when the ignition operation is 1232283 is operated, the firepower adjustment standard is forcibly turned. The dial can also achieve the effect of a short moving distance in the front and back direction of the fire button and easy to use.
