Description of the invention: [Technical field to which the invention belongs] Field of the invention This description relates to a gas control device for controlling the supply of fuel gas to a gas burner provided on a gas conditioning appliance such as a gas furnace. t The background of the previous invention. Such a gas control device, for example, known as Patent No. 2742356, has a gas control spare. For example, it is installed on the front panel of the gas furnace and can be moved in the direction of the fire button. At two different positions in the forward and backward direction of the gun fire button, there are closed positions for opening and maintaining the gas passage connecting the gas burner, actuating the ignition position of the gas burner ignition device and closing valve position for closing the gas passage. When you press the operating point flame-extinguishing oil from the valve closing position, the point-extinguishing button moves to the ignition position, opens the gas passage and activates the ignition device of the gas burner. After confirming that the gas burner is on fire, release the button of the point fire button, and then point the point of the fire button to move to the valve opening position. Interlocking When the valve is open, the thermal power adjustment of the ‘gas burner’ is performed by a ring-shaped thermal power adjustment dial located around the ignition stop. The fire power adjustment dial is set in the gas passage, and it is connected to the opening of the changing gas passage. The gas flow of the gas flow towards the gas burner fuel gas «If the adjustment device is pressed into the valve opening position, the gas passage can be blocked to make the gas To stop the combustion of the gas burner, click the fire button to move it to the valve closing position ^ 00404139 The gas burner is off. Here, during the ignition operation of the gas burner, in order to surely ignite the fuel gas, for example, it is appropriate to supply the fuel gas to the mixing pipe of the gas burner so that the fire power of the gas burner becomes a strong or medium fire. Therefore, a reset mechanism is provided in the two gas control devices. When the gas is annihilated, the reset mechanism is turned off to avoid the _entry operation. The disc is reset to a position where the fire power of the gas burner becomes stronger. Problem 10 to be solved by the invention. However, in recent years, in consideration of safety, and in order to ignite accidental contacts such as children, it is necessary to set off the so-called queen locking mechanism for in-service fire. Turn off the ignition button and move it towards the ignition position so that the ignition device will not move. At this time, if a safety 15 locking mechanism is provided in the above, due to the resetting, the firepower adjustment scale device cannot be turned. At the point of reducing the fire, press the closed valve plate of 4a. The ignition device at the position will not damage the gas working part, not only the number of parts, which will increase the cost of the material operation, but also in view of the above-mentioned shortcomings, the lock operation part can also be used in = No additional placement is required as a topic. Gas control for safe locking in closed position [Content of the invention] 20 200404139 In order to solve the problem 10 In order to solve the above-mentioned problem, the gas control device of the present invention includes an opening for keeping the gas passageway connected to the gas burner open. The m fire button, X, which can move freely in the forward and backward direction between the valve position and the valve closing position to block the gas passage. At this point, the fire button is pressed around. When it is located at the valve opening position of the fire button, the minimum gas flow is being supplied. A ring-shaped fire adjustment dial capable of rotating at least within the range of fire power adjustment is provided between the small fire power to the gas burner to make the fire power small and the strong fire power that supplies the largest gas to the gas burner to make the fire power strong. It is characterized in that: at the aforementioned closed position of the flame-out button, the firepower adjustment dial can be rotated freely beyond the firepower adjustment range 'and is equipped with a gas ignition device if the firepower adjustment dial is turned beyond the firepower adjustment range'. It cannot be locked.

If the ignition operation performed by the ignition device is ended and the remaining operation of the ignition is cancelled, press the ignition to open the valve. At this time, the gas passage remains open. At the valve opening position, if you turn the power adjustment scale = within the power adjustment range, you can increase or decrease the gas flow that is supplied to the gas device to take the shoulder as the power. Furthermore, in order to extinguish the gas burner, if the operating point fire button is moved from the valve open position to the closed position, the gas passage is blocked to stop supplying gas to the gas burner.
>在閉閥位置，可使火力調節刻度盤轉動超越火力調節 軌圍，但若將火力調節刻度盤轉動到所謂的安全鎖固之鎖 7 固位置，則點火裝置不作動。 閥位進行安全鎖固時，譬如，在將操作按知從閉 裝置之點mi 有作動瓦斯燃燒器點火 火按鈕11位置處，只要限制從點熄 火知紐的_位置朝點火位置之移動即可。 火，ΓΓ 斯燃燒器點火操作時，為確實使燃料瓦斯著 / 1供給燃料瓦斯使瓦斯燃燒器的火力變強或中。

10爐體21設有兩個瓦斯燃燒器23a、23b，且瓦斯燃燒器23a、 23b面臨設置於覆蓋其上面之面板22的兩個開口。 又在爐體21设置有位於設在其前面兩端的前面板24 之間的烤架25，且烤架25設置有陶瓷板式燃燒器（未圖示）。 而且，藉本發明之瓦斯控制裝置丨，控制朝兩個瓦斯燃燒器 15 23a、23b及陶瓷板式燃燒器燃料瓦斯之供給。 請參閱第2圖’瓦斯控制裝置1具有由上下重疊連結之 兩個部份11 a、1 lb所構成的閥殼體。在位於下側之閥殼體 ® 第1部份11a，設有沿著閥殼體縱向延伸之第丨内部通路 12a，並開設有連通第1内部通路12a之瓦斯流入部13。 2〇 位於瓦斯流入部13之下流侧，在第1内部通路12&設置 電磁閥3。電磁閥3具有磁鐵箱31，在該磁鐵箱31收容，譬 如按照來自設置於爐體21的控制設備（未圖示）的信號所激 磁之電磁鐵與被電磁鐵吸附之吸附片。 該吸附片連結由磁鐵箱31面向第1内部通路12a下流側 9 犬出之第1閥體32，在電磁閥3的閉閥狀態下，第1閥體32藉 細叹於该第1閥體32與電磁箱31之間之彈簧33賦與勢能的 力里’透過密封材34a落座於設置於第！内部通路12a之閥座 構造34之閥座中。 该電磁閥3的開閥操作係藉由隔著密封材41插設於第1 内部通路12a，並沿著第丨内部通路12a之縱向可前後移動自 如的操縱桿4來進行。 再者’在操縱桿4上設有第2閥體42，且第2閥體42與設 置於第1内部通路12a之閥座43—同構成主閥。在主閥的閉 閥狀態時，第2閥體42係藉縮設於第2閥體42與閥座構件34 之間之彈簧44落座於閥座43。 操縱桿4前後方向的移動係藉壓入操作由前面板24突 出設置之點熄火按鈕5來進行（參閱第1圖）。點熄火按鈕係呈 圓筒狀，且在其第1内部通路12a側端面，隨著點熄火按鈕5 的移動，可連結按壓操縱桿4之推桿5a。 再者，推桿5a的一端係連結設置於第1部份iia下側之 心形凸輪機構5b。此時，若壓入操作點熄火按鈕5以由從後 述火力調節刻度盤的頂端面突出且閉鎖第1内部通路12a之 閉閥位置（第1圖所示狀態）開始進行點火操作，則透過推桿 5a使操縱桿4被推壓向後方（第2圖右側）以開啟主閥之後，將 閥體32推開至吸附片側，且點火裝置之放電設備（未圖示） 移動到可作動之點火位置。 若從點火位置釋放點熄火按鈕5之按壓，則由心形凸輪 機構5b引導而朝前方向（第2圖左側）移動後，保持主閥開啟 以到達開放第1内部通路12a狀態之開閥位置 。為施行熄火 刼作而從開閥位置再壓入操作點熄火按鈕5時，心形凸輪機 構5b復位回到熄火位置。 再者’在位於主閥上流側之第1部份lla設置瓦斯流出 口 Ϊ4’该瓦斯流出口 14係與設置於第2部份llb之大致l字形 的第2内部通部12b之一端為一致，第丨及第2之各内部通路 12a、12b構成瓦斯通路。 在第2部份lib之外周面，隔著預定間隔相互隔絕地設 置四個第1、第2、第3及第4的各連通路15a、15b、15c、15d。 透過各連通路15a、15t)、i5c、15(i，且連結在第2部份nb 上部之瓦斯流出部16與第2内部通路12b連通。此時，各連 通路15a、15b、15c、15d之孔徑係朝前方逐漸增大而形成。 而且，從瓦斯流出部16流出之燃料瓦斯係朝瓦斯燃燒 器23a、23b及在陶瓷板式燃燒器的各混合管喷射燃料瓦斯 之瓦斯贺嘴（未圖示)供給。此時，為調節朝瓦斯喷嘴之燃料 瓦斯的瓦斯量，在第2内部通路12b設有流量調節閥6。 如第2圖及第3(a)與3(b)圖所示，流量調節閥6具有透過 密封材61a旋轉自如地設置於第2内部通路12b之圓筒形狀 的旋轉體61。在旋轉體161之外周面，四條圓周方向的第j、 第2、第3及第4之各長溝62a、62b、62c、62d係分別對應第 1、第2、苐3及第4之各連通路15a、15b、15c、15d而形成。 此時，各長溝62a、62b、62c、62d的寬度尺寸係分別與各 連通路15a、15b、15c、15d的孔徑一致且偏離圓周方向形 200404139 此外，在本實施形態，使形成有通過各連通路…、 15b、15c、15d朝瓦斯流出部16流出之燃料瓦斯之瓦斯流量 調節為預定量之四個節流孔口 63a、63b、63c、63d的孔口 構件63，與各連通路15a、l5b、l5e、15d一致並安裝於第2 5 部份lib外周面。 而且，旋轉旋轉體61，使各長溝62a、62b、62c、62d 與各連通路15a、15b、l5c、15d為適當地一致，可調節朝 瓦斯流出部16流出之燃料瓦斯的瓦斯流量。 旋轉體61之旋轉角的調節係藉設置於點媳火按紐5周 φ H)圍的火力調節刻度盤7來進行。如第4圖所示，火力調節刻 度盤7係在中空圓筒形狀之基部7加安裝環狀蓋所構成。 火力调節刻度盤7的第1内部通路lla側端部係以預定 螺距切齒，切齒之部份71與嵌合自第2部份爪突出的旋轉 體61 一端部之齒輪72喷合。因此，旋轉體61與火力調節刻 15度盤7之旋轉操作同步地旋轉。 在此，瓦斯燃燒器23a、23b點火操作時，為確實施行 使燃料瓦斯著火，譬如，為使瓦斯燃燒 器23a、23b的火力· 變強或中’則以將燃料瓦斯供給至瓦斯燃燒器23a、23b為 佳。 0 再者考慮到安全性，雖設有小孩等誤觸點熄火按鈕5 而放電設備不能作動之所謂的安全鎖固機構為佳，但由於 為達成女全鎖固而另外設置安全鎖固操作部會招致成本升 局。 多閱第2圖至第6(a)至6(e)圖，在本實施形態中，在自 12 前面板24突出之火力調節刻度盤7前向之内周面上形成凸 輪溝73，並且在朝前後方向移動通過之中空火力調節刻度 盤7内之點熄火按鈕5的外周面上設置與凸輪溝73成對之第 1突出片51以構成強制旋轉裝置。此時，第1突出片51係藉 5彈簧53賦與面向半徑方向外側勢能的狀態下，設置在設於 點媳火按紐外周面之半徑方向的孔52中。 由此，為使瓦斯燃燒器23a、23b點火，若從閉閥位置 壓入操作點熄火按鈕5，則第1突出片51變成主動段，將被 動段之凸輪溝73所形成之火力調節刻度盤7轉動到預定位 10 置。 此時，由於係利用點熄火按鈕5的壓入操作以轉動火力 調節刻度盤7 ’故，譬如，無須增大縮設於點熄火按鈕5與 第1部份11a之間之彈簧π之賦與勢能的力量，可簡化瓦斯 控制裝置之構造。 15 再者’凸輪溝的壁面高度係形成為隨著點媳火按紐5 的壓入操作從一方向另一方降低，而且，若從閉閥位置進 行點熄火按鈕5的壓入操作，則隨著點熄火按鈕5的移動第1 突出片51會被收納於前述孔52内，且到達從凸輪溝73朝縱 向延伸之平坦部74。 20 若再壓入操作點熄火按鈕5，則收納於前述孔52之第1 突出片51沿平坦部74移動到達點火位置。而且，作動放電 設備點燃瓦斯燃燒器23a、23b之後，若解除點熄火按紐5的 按壓，則受心形凸輪機構5b導引而藉彈簧5c賦與勢能的力 量稍微回位，且點熄火按鈕5到達開閥位置。 13 對應開閥位置在火力調節刻度盤7内周面，形成與平坦 部74同-平面的旋轉導引路75，且沿著旋轉料抑，火 力調節刻度盤7可於順時針方向或逆時針方向旋轉自如。 此時，被收納於孔52之第1突出片51未卡合凸輪溝73。 而且，若旋轉旋轉體61以使火力調節刻度盤7_時針方向 轉動，瓦斯流量減少，如朝逆時針方向轉動，則瓦斯流量 增加。 此時，旋轉體61係配置成若逆時針方向旋轉到設置於 火力調節刻度盤7的基部70a外周壁之凸部（未圖示）卡合設 置於爐體21讀止（未圖示），以限制火力調節刻度盤7的旋 轉範圍，則第2、第3及第4之各長溝㈣、61〇、创分別與 第2、第3及第4之各連通路15b、15c、I5d-致，使朝瓦斯 流出部16之瓦斯量變成最大。 另一方面，在第1長溝62a僅與第丨連通路15a一致之位 置處，將設置於點熄火按鈕5—端之突出部56接觸之止轉裝 置76設置於旋轉導引路75(參閱第6(勾至6(匀圖）中。 藉此，在開閥位置，火力調節刻度盤7可僅在使朝瓦斯 流出部16之瓦斯流量變成最小而使瓦斯燃燒器2%、2讣的 火力為小之小火力與使瓦斯流量變成最大而使瓦斯燃燒器 23a、23b的火力為強的強火力之間的火力調節範圍内自由 轉動，且旋轉導引路75的一端部與止轉裝置76構成旋轉範 圍限制裝置。 在此，為了使烹調者可輕易地調節火力，譬如，亦可 在瓦斯燃燒器23a、23b的火力變成弱及中之位置處會發生 200404139 叶°答聲。 如第3(a)與3(b)圖所示，在點熄火按鈕5的外周面設有 與第1突出片51相對之第2突出片54。此時，直徑比第1突出 片51小的第2突出片54係在藉彈簧56賦與朝半徑方向外側 5 勢能的狀態下設置在設於點熄火按鈕5外周面半徑方向的 孔55中。 再者，在旋轉導引路75之預定位置，分別形成僅可卡 合第2突出片Μ的半徑方向之第1及第2凹部77、88。而且， 譬如，將火力調節刻度盤7從最小流量（此時，瓦斯燃燒器 | 10 23&、23b的火力為小）朝逆時針方向轉動且使第2突出片54 卡合第1凹部77時，可發出咔嗒聲。此時，不但第丨長溝62a， 第2長溝62b亦與第2連通路15b—致而增加朝瓦斯流出部16 之瓦斯流量，使瓦斯燃燒器23a、23b的火力變弱。 再反時針方向轉動火力調節刻度盤7，若第2凹部78與第 15 2突出片54卡合則發生咔嗒聲。此時，不但第1及第2長溝 62a、62b，第3長溝62c亦與第3連通路15c一致而增加朝瓦斯 流出部16之瓦斯流量增加，使瓦斯燃燒器2如、2孙的火力變 鲁 成中。 再者，在點熄火按鈕5之閉閥位置形成有凸輪溝乃，使 2〇火力調節刻度盤7可順時針方向轉動超過火力調節範圍。若 超過火力調節範圍以將火力調節刻度盤7轉動到凸輪溝乃 端和則第1突出片51相對形成於凸輪溝73 一端部之操作 按鈕5的按壓方向卡合直角的壁部73a。 因此，無須為安全鎖固機構設置另外的操作部，即使 15 從閉闕位置至點火位置按壓點熄火按鈕5也不能使其移 動’可形成瓦斯燃燒||之點火裝置不能作動之鎖固位置。 此外’在設有安全鎖固機構時，最好使烹調者容易辨 "忍有安全鎖固之作用。在本實施形態中，如第7圖所示，在 叉調者容易注意的火力調節刻度盤7的上部設置窗部7a的 同時’於旋轉體61之預定位置附上紅色記號。而且，若轉 動火力a周節刻度盤7到鎖固位置，則可使該紅色記號與窗部 7a—致。 接著’利用瓦斯燃燒器23a說明本發明瓦斯控制裝置i 之動作。從第2圖所示閉閥位置，若施行點熄火按鈕5之按 壓操作，則可藉由第1突出片51與凸輪溝73之作用轉動火力 調節刻度盤7。 此時，旋轉體61係透過齒輪72旋轉，在該位置，第i、 第2及第3之各長溝62b、62c、62d分別與第1、第2及第3之 各連通路15b、15c、15d—致，可朝瓦斯流出部16流入瓦斯 燃燒器23a的火力為中之瓦斯流量之燃料瓦斯（參閱第^幻 圖及第11(a)與11(b)圖）。 若繼續點熄火按鈕5的按壓操作，如第8圖所示，則可 透過推桿5a向後方按壓操作桿4以開啟主閥，到達將閥體32 推開至吸附片侧之點火位置。 一旦到達點火位置，即藉放電設置施行瓦斯燃燒器23a 的點火操作。而且，一旦設置於瓦斯燃燒器23a近旁之火焰 檢出器件26(參閱第1圖）檢出瓦斯燃燒器23a的火焰，即以來 自控制設備的信號，使電磁閥激磁並保持開閥。 200404139 若確認瓦斯燃燒器23a已著火並解除點熄火按鈕5的按 壓，則點媳火按钮5受心形凸輪機構5b導引到達在第9圖所示 開閥位置。在開閥位置，主閥6藉操縱桿4之推壓作用而保持 開閥，同時火力調節刻度盤7可在火力調節範圍内轉動自如。 5 而且，為增強瓦斯燃燒器的火力，若使設於火力調節 刻度盤7的基部7〇a外周壁之凸部從中火位置逆時針方向旋 轉到卡合設於爐體21之鎖扣，則第2、第3及第4之各長溝 621)、62〇、62(1將分別與第2、第3及第4之各連通路151)、15〇、 bd—致，且瓦斯燃燒器23a的火力為強的瓦斯流量之燃料 馨 1〇瓦斯朝瓦斯流出部16流動（參閱第6(e)圖及第10(4與10〇}) 圖）。 另一方面，為從中火縮小瓦斯燃燒器23a的火力，若第 2犬出片54卡合第1凹部77後再順時針方向轉動火力調節刻 15度盤7直到發生咔嗒聲，則第1及第2之各長溝62a、62b分別 /、第1及第2之各連通路i5a、15b—致，且瓦斯燃燒器23a的 火力為弱之瓦斯流量之燃料瓦斯朝瓦斯流動（參閱第6(幻圖 及第3(a)與3(b)圖）。 _ 接著，若順時針方向轉動火力調節刻度盤7直到第1突 如出片51接觸止轉裝置76，則第！長溝62a僅與第i連通路… 致，且瓦斯燃燒器23a的火力為小的最小瓦斯流量之燃料 瓦斯朝瓦斯流出部10流動（參閱第^⑷與柳)圖及第石⑻ 圖）。 熄滅瓦斯燃燒器23a時，若從開閥位置向後方向按壓操 作點熄火按紐5，將使心形凸輪機構5b復位，且點媳火按叙5 17 承文彈黃5c之賦與勢能力量而從第2圖所示火力調節 般 7後退到突出之閉閥位置。 又皿 、 此時，推桿5a的推壓被解除之操縱桿4承受彈簧34之賦 $ "勢此力麗而向後方向移動，並關閉主閥。一旦主閥被關

The fuel gas flowing out of the gas outflow portion 16 is a gas nozzle that sprays fuel gas toward the gas burners 23a and 23b and each mixing pipe of the ceramic plate burner (not shown). At this time, in order to adjust the gas amount of the fuel gas toward the gas nozzle, a flow regulating valve 6 is provided in the second internal passage 12b. As shown in FIG. 2 and FIGS. 3 (a) and 3 (b) The flow regulating valve 6 includes a cylindrical rotating body 61 rotatably provided in the second internal passage 12b through a sealing material 61a. On the outer peripheral surface of the rotating body 161, there are four j-th, second, third and third circumferential directions. The fourth long grooves 62a, 62b, 62c, and 62d are formed corresponding to the first, second, third, and fourth communication paths 15a, 15b, 15c, and 15d. At this time, each of the long grooves 62a, 62b, and 62c is formed. The width dimensions of 62d and 62d are consistent with the diameters of the communication paths 15a, 15b, 15c, and 15d and deviate from the circumferential direction. 200404139 In addition, in this embodiment, the four gas flow orifices 63a, 63b, 63c are formed to adjust the gas flow rate of the fuel gas flowing toward the gas outflow portion 16 through the communication passages ..., 15b, 15c, and 15d to a predetermined amount.

The adjustment of the rotation angle of the rotating body 61 is provided by setting the ignition button for 5 cycles φ H) The surrounding firepower adjustment dial 7 is performed. As shown in Fig. 4, the thermal power adjustment scale 7 is formed by attaching a ring-shaped cover to the hollow cylindrical base portion 7. The end of the first internal passage 11a side of the thermal power adjustment dial 7 is cut with a predetermined pitch, and the cut portion 71 is sprayed with a gear 72 fitted into one end of the rotating body 61 protruding from the claw of the second portion. Therefore, the rotation body 61 rotates in synchronization with the rotation operation of the thermal power adjustment dial 7. Here, during the ignition operation of the gas burners 23a and 23b, in order to ensure the ignition of the fuel gas, for example, in order to make the firepower of the gas burners 23a and 23b strong or medium, the fuel gas is supplied to the gas burner 23a. 23b is preferred. 0 Furthermore, in consideration of safety, although a so-called safety lock mechanism including a misfire contact stop button 5 such as a child and the discharge device cannot be operated is preferred, a safety lock operation section is additionally provided to achieve a female lock Will incur cost increases. Read more about Figures 2 to 6 (a) to 6 (e). In this embodiment, a cam groove 73 is formed on the inner peripheral surface of the fire adjustment dial 7 protruding from the front panel 24, and A first protruding piece 51 paired with a cam groove 73 is provided on the outer peripheral surface of the flameout button 5 that moves through the hollow firepower adjustment dial 7 in the forward and backward direction to constitute a forced rotation device. At this time, the first protruding piece 51 is provided in a hole 52 provided in the radial direction of the outer peripheral surface of the ignition button with the potential energy facing the outside in the radial direction by the 5 spring 53. Therefore, in order to ignite the gas burners 23a and 23b, if the operation point extinguishing button 5 is pushed in from the valve closing position, the first protruding piece 51 becomes the active section, and the firepower adjustment dial formed by the cam groove 73 of the passive section is turned on. 7Rotate to the predetermined position 10. At this time, since the turning-off button 5 is turned by using the push-in operation of the point-extinguishing button 5, for example, it is not necessary to increase the amount of the spring π contracted between the point-extinguishing button 5 and the first portion 11a. The power of potential energy can simplify the construction of the gas control device. 15 Furthermore, the height of the wall surface of the cam groove is formed to be lowered from one direction to the other as the pressing operation of the ignition button 5 is pressed, and if the pressing operation of the ignition button 5 is performed from the valve closing position, The moving first protruding piece 51 of the ignition stop button 5 is received in the hole 52 and reaches the flat portion 74 extending from the cam groove 73 in the longitudinal direction. 20 When the operation point flameout button 5 is pushed in again, the first protruding piece 51 accommodated in the hole 52 moves along the flat portion 74 to reach the ignition position. Moreover, after activating the discharge device to ignite the gas burners 23a and 23b, if the pressing of the point-extinguishing button 5 is released, it is guided by the heart-shaped cam mechanism 5b and the force imparted by the potential energy by the spring 5c is slightly returned, and the button is clicked. 5 Reach the open valve position. 13 Corresponding valve opening position is on the inner peripheral surface of the thermal adjustment dial 7 to form a rotation guide path 75 on the same plane as the flat portion 74, and along the rotating material, the thermal adjustment dial 7 can be clockwise or counterclockwise. Rotate freely. At this time, the first protruding piece 51 received in the hole 52 is not engaged with the cam groove 73. Further, if the rotary body 61 is rotated to rotate the thermal adjustment dial 7_clockwise, the gas flow rate is reduced, and if it is rotated counterclockwise, the gas flow rate is increased. At this time, the rotating body 61 is arranged to rotate in a counterclockwise direction to a convex portion (not shown) provided on the outer peripheral wall of the base portion 70a of the thermal power adjustment dial 7 to be engaged with the furnace body 21 (not shown). To limit the rotation range of the dial 7 by adjusting the firepower, the second, third, and fourth long grooves, 61 °, and the communication paths 15b, 15c, and I5d of the second, third, and fourth, respectively. , So that the gas amount toward the gas outflow portion 16 becomes the maximum. On the other hand, at a position where the first long groove 62a coincides only with the first communication path 15a, a rotation preventing device 76 provided on the protruding portion 56 at the end of the click-extinguishing button 5 is provided on the rotation guide path 75 (see section 6 (Hook to 6 (even picture). With this, in the valve opening position, the firepower adjusting dial 7 can only reduce the gas flow rate toward the gas outflow portion 16 to minimize the gas power of the gas burner by 2% and 2 讣. For the small fire power and the strong fire power that maximizes the gas flow rate and makes the fire power of the gas burners 23a, 23b strong, the one end of the rotation guide 75 and the anti-rotation device 76 rotate freely. A rotation range limitation device is formed. Here, in order to allow the cook to easily adjust the firepower, for example, a 200404139 leaf ° answer can also occur at the position where the firepower of the gas burners 23a, 23b becomes weak and middle. As shown in Figs. (a) and 3 (b), a second protruding piece 54 opposite to the first protruding piece 51 is provided on the outer peripheral surface of the light-off button 5. At this time, the second protruding piece 51 having a smaller diameter than the first protruding piece 51 is provided. The protruding piece 54 is provided in a state where potential energy is applied to the outside 5 in the radial direction by the spring 56. In the hole 55 provided in the radial direction of the outer peripheral surface of the click-extinguishing button 5. Further, in the predetermined position of the rotation guide path 75, first and second recesses in the radial direction capable of engaging only the second protruding piece M are formed. 77, 88. Furthermore, for example, the fire power adjustment dial 7 is turned counterclockwise from the minimum flow rate (the fire power of the gas burner | 10 23 & 23b is small at this time) and the second protruding piece 54 is engaged with the first 1 when the recessed portion 77 is clicked. At this time, not only the first long groove 62a, the second long groove 62b, but also the second communication path 15b, and the gas flow rate toward the gas outflow portion 16 is increased, so that the gas burner 23a, The firepower of 23b is weakened. When the firepower adjustment dial 7 is turned counterclockwise, a click sound occurs when the second recess 78 and the 15th protruding piece 54 are engaged. At this time, not only the first and second long grooves 62a, 62b The third long groove 62c also coincides with the third communication path 15c and increases the gas flow rate toward the gas outflow portion 16 so that the firepower of the gas burners 2 and 2 becomes stable. Furthermore, when the stop button 5 is clicked, A cam groove is formed at the valve closing position, so that the 20 firepower adjusting dial 7 can be turned clockwise. If it exceeds the thermal power adjustment range to turn the thermal power adjustment dial 7 to the end of the cam groove, then the pressing direction of the first protruding piece 51 relative to the operation button 5 formed at one end of the cam groove 73 is engaged at a right angle. Wall part 73a. Therefore, there is no need to provide another operating part for the safety lock mechanism, even if 15 presses the point-extinguish button 5 from the closed position to the ignition position, it cannot be moved. Locking position. In addition, when a safety locking mechanism is provided, it is best to make it easy for cooks to recognize & bear the role of safety locking. In the present embodiment, as shown in Fig. 7, a red mark is attached to a predetermined position of the rotating body 61 while a window portion 7a is provided on the upper portion of the fire adjustment dial 7 which is easy for a fork adjuster to pay attention to. In addition, if the heating power a weekly dial 7 is turned to the locked position, the red mark can be matched with the window portion 7a. Next, the operation of the gas control device i of the present invention will be described using the gas burner 23a. From the valve closing position shown in FIG. 2, if the pressing operation of the point flameout button 5 is performed, the firepower adjustment dial 7 can be rotated by the action of the first protruding piece 51 and the cam groove 73. At this time, the rotating body 61 is rotated through the gear 72, and at this position, the respective long grooves 62b, 62c, and 62d of the i, the second, and the third are connected to the first, second, and third communication channels 15b, 15c, and 15d—To the fuel gas that can flow into the gas burner 23a toward the gas outflow portion 16 at a medium gas flow rate (see Figure ^ and Figures 11 (a) and 11 (b)). If the pressing operation of the flameout button 5 is continued, as shown in FIG. 8, the main valve can be opened by pushing the operation lever 4 backward through the push rod 5 a to reach the ignition position where the valve body 32 is pushed to the side of the adsorption sheet. Once the ignition position is reached, the ignition operation of the gas burner 23a is performed by the discharge setting. When the flame detecting device 26 (see Fig. 1) installed near the gas burner 23a detects the flame of the gas burner 23a, the signal from the control device excites the solenoid valve and keeps it open. 200404139 If it is confirmed that the gas burner 23a is on fire and the pressing of the ignition-off button 5 is released, the ignition-off button 5 is guided by the heart-shaped cam mechanism 5b to the valve opening position shown in FIG. In the valve-opening position, the main valve 6 is kept open by the pushing action of the control lever 4, and at the same time, the thermal power adjustment dial 7 can rotate freely within the thermal power adjustment range. 5 In addition, in order to enhance the firepower of the gas burner, if the convex portion provided on the outer peripheral wall of the base portion 70a of the firepower adjusting dial 7 is rotated counterclockwise from the middle fire position to the latch provided on the furnace body 21, The 2nd, 3rd, and 4th long grooves 621), 62 °, 62 (1 will be respectively connected to the 2nd, 3rd, and 4th communication paths 151), 15 °, and bd, and the gas burner 23a The fuel gas 10, whose firepower is a strong gas flow, flows toward the gas outflow portion 16 (see Figure 6 (e) and Figures 10 (4 and 10)). On the other hand, in order to reduce the firepower of the gas burner 23a from medium fire, if the second dog-out piece 54 engages the first recessed portion 77 and then rotates the firepower adjustment dial 15 clockwise 7 clockwise until a click occurs, the first And the second long grooves 62a, 62b respectively, and the first and second communication paths i5a, 15b, and the gas burner 23a has a weak gas flow, and the fuel gas flows toward the gas (see section 6 ( (Magic and 3 (a) and 3 (b)). _ Then, if the fire power adjustment dial 7 is turned clockwise until the first protruding piece 51 contacts the anti-rotation device 76, the first! Long groove 62a and the first The communication path i is the same, and the fuel gas with the minimum gas flow rate of the small gas flow rate of the gas burner 23a flows toward the gas outflow portion 10 (see the figure ^ 柳 and willow) and the figure ⑻⑻). When the gas burner 23a is extinguished, if the operating point flameout button 5 is pressed from the valve opening position in the backward direction, the heart-shaped cam mechanism 5b will be reset, and the flame will be fired according to 5 17 Cheng Wen Dan Huang 5c. And retreat from the heat regulation 7 shown in Figure 2 to the protruding closed valve position. At this time, the lever 4 that has been released from the push of the push rod 5a receives the force of the spring 34, and moves in the backward direction, and closes the main valve. Once the main valve is closed, the supply of fuel gas to the gas burner 23a is stopped and the flame is turned off. If the control detects that the flame has been extinguished by the flame detection device 26, the solenoid valve 3 is closed. Finally, at the valve closing position, if the thermal power adjustment dial is turned clockwise along the cam groove 73 beyond the thermal power adjustment range, the first protruding piece 51 will engage the wall portion 73a of the cam groove 73 so that the flameout button 5 cannot be turned on. Pressed and locked by safety φ 10. Referring to Figs. 13 to 15, 100 indicates a gas control device according to a second embodiment. This gas control device 100 differs from the above-mentioned embodiment in that, for example, when the soup overflows from a cooking appliance such as a pan during fork adjustment, if the firepower is withered, that is, the dial 7 is turned in one direction, the gas burner can be stopped. 23a, 2 make up for burning 15 burn. · At this time, a first protruding portion 5 (Π) having a substantially triangular cross section is formed at a predetermined position of the fire-extinguishing button 5. At the same time, corresponding to the protruding portion 501, the inner peripheral surface of the dial 7 is formed to face inward. The second protruding portion 502 protruding from the square. The second protruding portion 502 is formed so as to turn the thermal power adjustment dial 7 in a 20-ton clockwise direction at the valve opening position of the light-off button 5 to abut the first protruding portion 501. (See Figure 15 (a).) At this time, the first long hole 62a of the rotating body 161 is only the same as the first communication path 15a. Therefore, the second protruding portion 502 has a minimum setting toward the gas outflow portion 16 The effect of the anti-rotation device of the thermal adjustment dial 7 of the gas flow rate. 18 200404139 Turn the thermal adjustment dial 7 clockwise from the position where the second protrusion 502 abuts the first protrusion 501, and the second protrusion 502 is at The first protrusion 501 slides on the inclined surface 501a (see FIG. 15 (b)). — At this time, the fire button 5 is pressed forward, and if the second protrusion 502 passes through the first protrusion 501 The inclined surface 501a resets the heart-shaped cam mechanism 讣 at the same time (see Figure 15 (c)). At this time, press the fire button 5 Under the force of the potential energy given by the spring 5C, the flameout button 5 is returned to the closed position (see figure i5 (d)). Therefore, 'except for the operation point firework button 5 to extinguish the gas combustion 23a, 23b, the first Each of the first and second protrusions 501 and 502 becomes a forced moving device for turning off the flame 10 button 5 and turning the fire adjustment dial 7 in one direction to extinguish the flames of the gas burners 23a and 23b, so that the gas conditioning appliance can be improved. Convenience. However, in the first and second embodiments, although the fire power adjustment dial 7 and the rotating body 61 are rotated synchronously through the gear mechanisms 71 and 72, it is not limited to 15 and may be a belt mechanism. The fire power adjustment dial 7 is rotated in synchronization with the rotating body 61.
