Description of the invention: [Technical field to which the invention belongs] Field of the invention The present invention relates to a gas control device for controlling the supply and supply of fuel gas to gas installed in a gas furnace, etc. ', and " Zhou Li is a gas burner equipped with the above. Prior art] Background of the invention 10 15 20 Such a gas control device is known, for example, from Japanese Patent No. 2742356. The gas control device includes, for example, a fire button which is provided on the front panel of the gas furnace and can move freely in the front-rear direction. At the point where the flameout is stopped, the gas burner is provided at three different positions in the front-rear direction. When the gas passage is opened, the ignition position of the ignition device of the gas burner and the valve closing position for closing the gas passage are activated. If the operating point fire button is pressed from the valve closing position, the fire button is moved to the ignition position, the gas passage is opened, and the ignition device of the gas burner is activated. If the ignition button is released after confirming that the gas burner is on fire, the flameout button is pressed to move to the valve opening position. The power adjustment of the W burner is performed by setting a ring-shaped power adjustment dial at the point of fire. The hot plate is installed in the gas passage, and the toilet is changed ^ r …… ... The opening area of the gas passage is adjusted to adjust the linkage of fuel gas towards the gas burner. The gas flow control device of the "Li Zhi" 5 1226422 gas burner burns. Here, to ensure that the fuel gas is actually ignited during the ignition operation of the gas burner, for example, the fuel gas should be supplied to the mixing pipe of the gas burner so that The fire power of the gas burner becomes strong or medium fire. 5 Therefore, a reset mechanism is provided in the aforementioned gas control device, and when the gas burner is extinguished, the reset mechanism is linked with the press-in operation of its ignition button to adjust the scale of the fire power. The disk is forcibly rotated to reset the fire adjustment dial to a position where the fire power of the gas burner becomes stronger.
發明欲解決之課題 10 可是，近年來，考慮安全性，且為了使小孩等誤觸點 熄火按鈕瓦斯燃燒器也不作動，在點熄火按鈕設置所謂的 安全鎖固機構，譬如，大多在閉閥位置限制點熄火按鈕朝 點火位置移動，使點火裝置不作動。Problem 10 to be solved by the invention However, in recent years, safety is considered, and in order to prevent accidental contact of the gas burner such as a child, the gas burner does not operate, and a so-called safety lock mechanism is provided at the flameout button. The position limit point flameout button is moved toward the ignition position, so that the ignition device is not activated.
此時，若在上述者設置安全鎖固機構，則由於設有復 15 位裝置，在點減火按鈕的閉閥位置不能轉動火力調節刻度 盤。 因此，雖可考慮另外附設安全鎖固操作部，使在閉閥 位置處點火裝置不作動，但設置另一個操作部，不只會特 別地損害瓦斯燃燒器點火操作時的操作性，而且亦會增加 20 零件數目，使成本變高。 鑑於上述缺點，本發明提供一種無須設置另外的安全 鎖固操作部，亦可在閉閥裝置進行安全鎖固之瓦斯控制裝 置作為課題。 【發明内容】 6 1226422 為解決課題之手段 為解決上述課題，本發明之瓦斯控制震置包含有可在 使連通至瓦斯燃燒器之瓦斯通路保持開放之開闊位置與閉 鎖該瓦斯通路之閉閥位置之間於前後方向移動自如的點媳 5火按紐，又，在該點熄火按鈕的周圍，當位於點媳火按紐 的開閥位置時’在供給最小瓦斯流量至瓦斯燃燒器以使火 力為小之小火力與供給最大瓦斯至瓦斯燃燒器以使火力為 強的強火力之間，設置有至少可在火力調節範圍内旋轉自 如的環狀火力調節刻度盤，其特徵在於：於前述點媳火按 鈕的閉閥位置，火力調節刻度盤可旋轉自如地超出火力調 節範圍，並設有若轉動火力調節刻度盤超過該火力調節範 圍’則瓦斯燃燒器之點火裝置就不能作動之鎖固位置。 根據本發明’若從閉閥位置操作點熄火按紐朝一方移 動，則可開放瓦斯通路，使燃料瓦斯流至瓦斯燃燒器，並 15作動點火裝置。如以點火裝置進行之點火操作結束而解除 點炮火按鈕的操作，則點媳火按紐到達開閱位置。此時， 瓦斯通路保持在開放狀態。 於開閥位置，若在火力調節範圍内轉動火力調節刻度 盤丄則可增減供給至瓦斯燃燒器之燃料瓦斯的瓦斯流量以 2〇調節火力。而且，為媳滅瓦斯燃燒器，若操作點媳火按姐 從開閥位置移動至閉閥位置，則瓦斯通路被閉鎖，以停止 朝瓦斯燃燒器供給燃料瓦斯。 Μ在閉閥位置，可使火力調節刻度盤轉動超越火力調節 1巳圍’但右將火力調節刻度盤轉動到所謂的安全鎖固之鎖 ^26422 固位置，則點火裝置不作動。 心進行安全鎖固時，譬如，在將操作按知從閉 襄置之胃_位置移動路徑途中設有作動瓦斯燃燒器點火 ·έ火位置，且在前述鎖固位置處，只要限制從畔自 人按知的_位置朝點火位置之移動即可。 火，Γ者，瓦難燒11點火操作時，為確實㈣料瓦斯著

述點媳火按紐的開閥位置，使火力調節刻度盤可超過火力 1226422 调節範圍而於小火力側旋轉自如，且若超過小火力位置後 轉動火力調節刻度盤，則強制移動點熄火按鈕至閉閥位置。 此外，亦可設有當珂述火力調節刻度盤位於前述鎖固 位置時，可辨識出前述點火裝置不作動之顯示裝置，以使 5 烹調者能容易辨識已有安全鎖固。 I：實施方式3 發明之實施形態 參閱第1圖，第1實施形態之瓦斯控制裝置丨係組合於， 譬如，瓦斯爐2中。此時，瓦斯爐2具有箱狀的爐體21，在 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設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、2补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、11 b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1内部通路 12a，並開設有連通第丨内部通路12a之瓦斯流入部13。 20 位於瓦斯流入部13之下流側，在第1内部通路12a設置 電磁閥3。電磁閥3具有磁鐵箱31，在該磁鐵箱31收容，嬖 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 1226422 突出之第1閥體32,在電磁閥3的閉閥狀態下，第丨閥體32藉 縮設於該第1閥體32與電磁箱31之間之彈箐％賦與勢能的 力ϊ ’透過密封材34a落座於設置於第1内部通路12a之閥座 構造34之閥座中。 5 该電磁閥3的開閥操作係藉由隔著密封材41插設於第1 内口卩通路12a，並沿著第1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 1〇閥狀您時，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以突 出设置之點熄火按鈕5來進行（參閱第丨圖）。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 15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丨部份Ua下側之 心形凸輪機構5b。此時，若壓入操作點熄火按紐5以由從後 述火力調節刻度盤的頂端面突出且閉鎖第1内部通路丨2 a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 20 %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 1226422 乂到達開放第1内部通路Ua狀態之開閥位置。為施行媳火 操作而從開閥位置再壓入操作點媳火按钮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11a設置瓦斯流出 5 口 14’该瓦斯流出口 14係與設置於第2部份lib之大致L字形 的第2内部通部12b之一端為一致，第1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^，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k各連通路15a、15b、i5c、i5d，且連結在第2部份仙 上部之瓦斯流出部16與第2内部通路121>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 态23a、23b及在陶瓷板式燃燒器的各混合管喷射燃料瓦斯 15之瓦斯噴嘴（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i、 20第2、第3及第4之各長溝62a、62b、62c、62d係分別對應第 1、第2、第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 成0 1226422 &外’在本實施形態 15b、15e、l5_F#、 _成有通過各連通路15a、 調節為預定量之四個？:：164出之燃料瓦斯之瓦斯流量 構件-與各連通ΓΓ 、63b、63e、6w 部份llb外周面。a、5b、l5c、⑸一致並安裝於第2 而且，旋轉旋轉體61 與各連通路l5a、l5b、1s長溝 _ ^ , r c、I5d為適當地一致，可調節朝 瓦斯流出部16流出之_瓦_瓦斯流量。 10 15 2〇 鬥之&轉角的調節係藉設置於點媳火按姐5周 圍的火力調節刻度盤7來 度觸在圖所不，火力調節刻 、上& 小狀之基部7〇a安裝環狀蓋70b所構成。 、力周命刻度盤7的第1内部通路⑴側端部係 以預定 骑刀ω㈣之部份71與嵌合自第2部份別突出的旋轉 ^一端部之齒輪72嗔合。因此，旋轉體61與火力調節刻 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 吏‘‘、’、料瓦斯著火’譬如’為使瓦斯燃燒器仏、现的火力 變強或中’則以將燃料瓦斯供給至瓦斯燃燒器23a、23b為 佳。 再者’考慮到安全性，雖設有小孩等誤觸點媳火按鈕5 而放電設備不能作狀所謂的安全細機構為佳 ，但由於 $達成女全鎖m而另外設置安全鎖固操作部會減成本升 兩0 茶閱第2圖至第6(a)至6(e)圖，在本實施形態中，在自 12 1226422 則面板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，亚且在朝所後方向移動通過之中空火力調節刻度 盤7内之點媳火按紐5的外周面上設置與凸輪溝乃成對之第 1突出片51以構成強制旋轉裝置。此時，第i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 點熄火按鈕外周面之半徑方向的孔52中。 由此，為使瓦斯燃燒器23a、⑽點火，若從閉闊位置 堡入操作點總火按紐5，則第i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，無須增大縮設於點媳火按紐5與 第1部份1U之間之彈簧以之賦與勢能的力量，可簡化瓦斯 控制裝置之構造。 15 β、再者，凸輪溝73_面高度係形成為隨著祕火按紐5 的£入&作彳< 方向另_方降低，而且，若從閉閥位置進 H火4^5的壓人操作’則隨著點媳火按奶的移動第工 大出片51曰被收納於前述孔52内，且到達從凸輪溝乃朝縱 向延伸之平坦部74。 若再屋人操作轉火独5，職納於前述孔52之第i 20 突出片51沿平坦部74移關達敎位置。而且，作動放電 =點燃味錢㈣a、现之後，若解除減火按鈕5的 松1 ⑼凸輪機構5b導引而II彈簣5e賦與勢能的力 量稍微回位’且點熄火按钮5到達開閥位置。 13 1226422 對應開閥位置在火力調節刻度盤7内周面，形成盘平括 部74同-平面的旋轉導引路75，且沿著旋轉導引物，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W Μ未卡合凸輪溝73。 5而且，若旋轉旋轉體61以使火力調節刻度盤7朝順時針方向 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 籲參 10置於爐體21之擒止（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^卜咖分別與 第2、第3及第4之各連通路15b、1Sc、⑸一致，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 15置處，將设置於點熄火按鈕5一端之突出部56接觸之止轉裝 置76設置於旋轉導引路75(參閱第6(a)至6(e)圖）中。 藉此，在開閥位置，火力調節刻度盤7可僅在使朝瓦斯 •每 流出部16之瓦斯流量變成最小而使瓦斯燃燒器23&、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 2〇 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 14 1226422 味°荅聲。 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5 5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54的半徑方向之第1及第2凹部77、88。而且， 鲁如’將火力調節刻度盤7從最小流量（此時，瓦斯燃燒器 1〇 23a、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， 第長溝62b亦與弟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大出片54卡合則發生咔嗒聲。此時，不但第1及第2長溝 62b第3長溝62c亦與第3連通路15c—致而增加朝瓦斯 机出部16之瓦斯流量增加，使瓦斯燃燒器〕％、2几的火力變 鲁鲁 成中。 再者，在點熄火按紐5之閉閥位置形成有凸輪溝73，使 20火力.周即刻度盤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73 端和則第1突出片Μ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’然須為安全鎖固機構設置另外的操作部，即使 15 1226422 從閉閥位置至點火位置按壓點熄火按紐5也不能使其移 動，可形成瓦斯燃燒器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 認有安全鎖固之作用。在本實施形態中，如第7圖所示，在 5 j，周者各易，主思的火力調節刻度盤7的上部設置窗部％的 同時，於旋轉體61之預定位置附上紅色記號。而且，若轉 動火力調節刻度盤7到細位置，則可使該紅色記號與窗部 7a—致0 接著矛J用瓦斯燃燒裔23a說明本發明瓦斯控制裝置1 10之動作。從第2圖所示閉閥位i，若施行點媳火按紐5之按 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。 此日寸，疑轉體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 15各連通路15b、15c、15d-致，可朝瓦斯流出部16流入瓦斯 燃燒态2 3 a的火力為中之瓦斯流量之燃料瓦斯（參閱第6 (d) 圖及第11(a)與11(b)圖）。 若繼續點熄火按钮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& 2〇 推開至吸附片側之點火位置。 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。 16 1226422 若確認瓦斯燃^23a已著火並解除點媳火按紐5的按 壓，則點熄火按紐5受心形凸輪機構％導引到達在第9圖所示 開闊位置。在開閥位置，主閥6藉操縱桿4之推壓作用而保持 開闊，同時火力調節刻度盤7可在火力調節範圍内轉動自如。 5 %且，為增強瓦斯燃燒器的火力，若舰於火力調節 刻度盤7的基部7〇叫懸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 62b、62c、62d將分別與第2、第3及第4之各連通路15卜以、 ⑸-致’且瓦斯燃燒器23a的火力為強的瓦斯流量之燃料 H)瓦斯朝瓦斯流出部16流動（參閱第6(e)圖及第i〇(a)與剛 圖）。 另一方面，為從中火縮小瓦斯燃燒器23a的火力，若第 2突出片54卡合第！凹部77後再順時針方向轉動火力調節刻 度盤7直到發生十荅聲，則第【及第2之各長溝心、咖分別 15與第i及第2之各連通路15a、15b 一致，且瓦斯燃燒器仏的 火力為弱之瓦斯流量之燃料瓦斯朝瓦斯流動（參閱第6⑷圖 及第3(a)與3(b)圖）。 接著若順日寸針方向轉動火力調節刻度盤7直到第1突 扣2片接觸止轉裝置76 ’則第！長溝—僅與第i連通路… 致且瓦斯燃燒益23a的火力為小的最小瓦斯流量之燃料 瓦斯朝瓦斯流出部Μ流動（參閱扣⑷與邮)圖及第6(b) 圖）。 熄滅瓦斯燃燒器23a時，若從開閥位置向後方向按壓操 作點熄火按鈕5，將使心形凸輪機構5b復位，且點熄火按鈕5 17 1226422 承受彈簧5c之賦與勢能力量而從第2圖所示火力調節刻度盤 7後退到突出之閉閥位置。 此時，推桿5a的推壓被解除之操縱桿4承受彈簣34之賦 與勢能力量而向後方向移動，並關閉主閥。一旦主閥被關 5閉，即停止朝瓦斯燃燒器23a供給燃料瓦斯而熄火。若控制 器辨認藉火焰檢出器件26火焰已熄，則關閉電磁閥3。 表後，在閉閥位置，若沿著凸輪溝73使火力調節刻度 盤順時針方向轉動超過火力調節範圍，則第丨突起片51將卡 合凸輪溝73的壁部73a，使點熄火按鈕5不能按壓且被安全 10 鎖固。 請參閱第13圖至第15圖，100表示第2實施形態之瓦斯 控制裝置。該瓦斯控制裝置1〇〇與上述第丨實施形態不同點 係，譬如，烹調時從鍋等烹調器具溢出湯汁時，若使火力 調節刻度盤7單向轉動，則可停止瓦斯燃燒器23&、2孙之燃 15 燒。 此時，在點熄火按鈕5之預定位置形成截面大致三角形 的第1突起部501，同時對應該突起部5〇1，在火力調節刻度 盤7的内周面形成有朝其内方突出之第2突起部502。 第2突起部5〇2係形成為若在點熄火按鈕5的開閥位置 20順時針方向轉動火力調節刻度盤7，則與第1突起部501抵接 (麥閱第15(a)圖）。此時，旋轉體161的第1長孔62a僅與第1 連通路15a—致。因此，第2突起部5〇2具有作為設定朝瓦斯 流出部16最小瓦斯流量的火力調節刻度盤7止轉裝置之效 果。 18 1226422 若從第2突起部502抵接第1突起部501之位置順時針方 向再轉動火力調節刻度盤7，則第2突起部502在第1突起部 501之傾斜面5〇la上滑動（參閱第15(b)圖）。 此時，點熄火按鈕5向前方壓入，若第2突起部502通過 5

It is characterized in that: The valve position of the fire button, the fire adjustment dial can be rotated freely beyond the fire adjustment range, and there is a locked position where the ignition device of the gas burner cannot be operated if the fire adjustment dial is turned beyond the fire adjustment range. . According to the present invention ', if the extinction button is moved to one side from the operating point of the valve closing position, the gas passage can be opened, the fuel gas can flow to the gas burner, and the ignition device can be activated. If the ignition operation is terminated by the ignition device and the operation of the fire button is cancelled, the fire button is reached to the reading position. At this time, the gas passage remains open. At the valve opening position, if you turn the power adjustment dial 丄 within the power adjustment range, you can increase or decrease the gas flow of the fuel gas supplied to the gas burner to adjust the power. Furthermore, in order to extinguish the gas burner, if the operating point of the flame burner is moved from the valve opening position to the valve closing position, the gas passage is blocked to stop supplying fuel gas to the gas burner. In the closed valve position, the fire adjustment dial can be rotated beyond the fire adjustment 1 巳 circle ', but if the fire adjustment dial is turned to the so-called safety lock position ^ 26422 on the right, the ignition will not operate. When the heart is locked securely, for example, an operating gas burner ignition and fire position is set on the way of the operation from the closed position of the stomach to the operation position, and at the aforementioned locked position, as long as the Just press the known _ position toward the ignition position. The fire, Γ, and the dynamite burner 11 Ignite the gas during the ignition operation. For example, it is advisable to supply fuel gas to make the firepower of the gas burner strong or medium. The land preparation can also be provided with a forced rotation device that can perform the ignition operation of the aforementioned point-extinguish button, and then turn the fire adjustment dial as described above to turn the fire power of the gas burner into a fire force. In addition, it can be said that if the ignition operation is to move the closed button to the ignition position using the push-in button of the point-extinguish button, you can use the pressing force of ^ 3 to maintain the firepower by the forced rotation device. The adjustment dial can be turned around, for example, to simplify the structure of the device. Bu can also be located at the valve position of the # 述 点 媳 火 button, with a rotation range restriction dress which limits the rotation range of the firepower dial to the firepower adjustment range, so that the firepower adjustment dial cannot be above the firepower adjustment range.

In the closed state of the solenoid valve 3, the first valve body 32 is contracted and provided on the first valve body 32. The force imparted by the impulse% with potential energy to the electromagnetic box 31 ′ is seated in the valve seat of the valve seat structure 34 provided in the first internal passage 12 a through the sealing material 34 a. 5 The opening operation of the solenoid valve 3 is performed by a joystick 4 which is inserted in the first inner port 卩 passage 12a through the sealing material 41 and is movable back and forth along the longitudinal direction of the first inner passage 12a. Furthermore, a second valve body 42 is provided on the joystick 4, and the second valve body 42 and the valve seat 43 provided in the first internal passage 12a constitute the same main valve. When closing the main valve of the main valve, the second valve body 42 is seated on the valve seat 43 by a spring 44 retracted between the second valve body 42 and the valve seat member 34. The movement of the joystick 4 in the forward-backward direction is performed by pressing the push-out button 5 on the front panel to protrude from the setting point (see FIG. 丨). The light-off button is cylindrical, and on the end surface of the first internal passage 12a side, as the light-off button 5 15 moves, the pusher 5a of the joystick 4 can be connected. Furthermore, one end of the push rod 5a is connected to a heart-shaped cam mechanism 5b provided below the first portion Ua. At this time, if the push-in operation point extinction button 5 is pressed to start the ignition operation by protruding from the top surface of the power adjustment dial described later and closing the valve position of the first internal passage 2a (the state shown in FIG. 1), Then, the lever 4 is pushed to the rear (right side of Fig. 2) through the push rod 20% to open the main valve, then the valve body 32 is pushed to the side of the adsorption sheet, and the discharge device (not shown) of the ignition device is moved to Acting ignition position. If the pressing of the flameout button 5 is released from the ignition position, it will be guided by the heart-shaped cam mechanism 5b and moved forward (left side of Fig. 2), and the main valve will be kept open 1226422. 乂 It will open when the first internal path Ua is opened. position. When the operation point fire button 5 is pushed in again from the valve opening position to perform the fire operation, the heart-shaped cam mechanism 5b is returned to the fire stop position. In addition, a gas outflow port 14 ′ is provided in the first portion 11a located on the upstream side of the main valve. The gas outflow port 14 is connected to one end of the second L-shaped internal communication portion 12b provided in the second portion lib. In agreement, each of the first and second internal passages 12a and 12b constitutes a gas passage. Outside the second part lib ^, four first, second, third, and fourth communication paths 15a, 15b, 15c, and 15d are provided in isolation from each other at predetermined intervals. Each of the communication paths 15a, 15b, i5c, and i5d passes through the gas outflow portion 16 connected to the upper part of the second part and communicates with the second internal passage 121>. At this time, the apertures of each of the continuous passages 15a, 15b, 15c, and 15d are gradually increased toward the front and formed. The fuel gas flowing from the gas outflow portion 16 is supplied to the gas combustion states 23a, 23b and a gas nozzle (not shown) that injects the fuel gas 15 at each mixing pipe of the ceramic plate burner. At this time, a flow regulating valve 6 is provided in the second internal passage 12b to adjust the gas amount of the fuel gas toward the gas nozzle. As shown in Fig. 2 and Figs. 3 (a) and 3 (b), the flow regulating valve 6 includes a cylindrical rotating body 61 which is rotatably provided in the second internal passage 12b through a sealing material 61a. On the outer peripheral surface of the rotating body 161, the four i-th, 20th, second, third, and fourth long grooves 62a, 62b, 62c, and 62d in the circumferential direction correspond to the first, second, third, and fourth ones, respectively. The communication paths 15a, 15b, 15c, and 15d are formed. At this time, the width dimension of each of the long grooves 62a, 62b, 62c, and 62d is consistent with the hole diameter of each of the communication paths 15a, 15b, 15c, and 15d and deviates from the circumferential direction to form 0. 1226422 & In this embodiment 15b, 15e, l5_F #, _Are there four through each communication path 15a, adjusted to a predetermined amount? ::: Gas flow rate of fuel gas from 164. Component-communicates with the outer peripheral surface of part llb of ΓΓ, 63b, 63e, 6w. a, 5b, l5c, and ⑸ are aligned and installed on the second. Moreover, the rotating and rotating body 61 and the communication paths 15a, 15b, and 1s have long grooves _ ^, rc, I5d, which are appropriately consistent with each other. Watt_gas flow. 10 15 2〇 The adjustment of the & corner is by setting the fire power adjustment dial 7 around the sister 5 to touch the position shown in the figure. The fire power is adjusted and the & small base 7〇a It is comprised by attaching the ring-shaped cover 70b. The first internal passage ⑴ side end of the force dial plate 7 is a portion 71 of a predetermined riding knife ω㈣ and a rotating gear 72 fitted at one end of the second portion protruding from the second portion. Therefore, the rotating body 61 rotates in synchronization with the rotation operation of the thermal power adjustment dial 7. Here, when the gas burners 23a and 23b are being ignited, in order to perform the operation, the fuel gas is burned. For example, to make the gas burner stubborn, the current firepower becomes stronger or medium, the fuel gas is supplied to The gas burners 23a and 23b are preferred. Furthermore, in consideration of safety, although it is better to provide a misfire contact 5 such as a child with the fire button 5 and the discharge device cannot act as a so-called safety fine mechanism, a safety lock operation unit is additionally provided because the female lock is reached. It will reduce the cost and increase the cost by two. Please refer to Figures 2 to 6 (a) to 6 (e). In this embodiment, the inner circumferential surface of the fire adjustment dial 7 protruding from the 12 1226422 panel 24 is directed forward. A cam groove 73 is formed on the upper side, and the first protruding piece 51 paired with the cam groove is provided on the outer peripheral surface of the fire button 5 to move through the hollow fire adjustment dial 7 in the backward direction to constitute a force. Rotating device. At this time, the i-th protruding piece 51 is provided in a hole 52 provided in the radial direction of the outer peripheral surface of the click-extinguishing button in a state where potential energy facing the outside in the radial direction is imparted by the 5 spring 53. Therefore, in order to ignite the gas burner 23a and thorium, if the total fire button 5 is entered from the closed position to the operating point, the i-th protruding piece 51 becomes the active section, and the firepower formed by the cam groove 73 of the passive section is adjusted. The dial 7 is rotated to a predetermined position 10. At this time, since the pressing-out operation of the point-extinguishing button 5 is used to turn the power adjustment dial 7, for example, there is no need to increase the spring retracted between the point-extinguishing button 5 and the first part 1U. Potential energy can simplify the structure of the gas control device. 15 β. Moreover, the cam groove 73_ plane height is formed to decrease with the direction of the fire button 5 and the direction of the other side, and if it enters the fire from the valve closing position 4 ^ 5 The "pressing operation" is followed by the movement of the milk and the milk is moved into the hole 52, and reaches the flat portion 74 extending from the cam groove to the longitudinal direction. If another person operates Zhuanhuodu 5, the i 20th projecting piece 51 in the hole 52 is moved to the position along the flat portion 74. Moreover, actuated discharge = ignite the flavor ㈣a. Now, if the release button 1 of the fire reduction button 5 is released, the cam mechanism 5b guides and the force of the potential energy given by the II bomb 5e returns slightly, and the fire button 5 is reached to open the valve. position. 13 1226422 Corresponding to the valve opening position is on the inner peripheral surface of the fire adjustment dial 7, forming a disk guide 74 in the same plane as the rotation guide 75, and along the rotation guide, the fire adjustment dial 7 can be clockwise Or rotate freely counterclockwise. At this time, the first protrusion WM accommodated in the hole 52 is not engaged with the cam groove 73. 5 Also, if the rotary body 61 is rotated to turn the firepower adjusting dial 7 clockwise, the gas flow rate decreases, and if it rotates counterclockwise, the gas flow rate increases. At this time, the 'rotating body 61' is configured to rotate counterclockwise to a convex portion (not shown) provided on the outer peripheral wall of the base portion 70a of the thermal power adjustment dial 7 and engage the reference body 10 to be placed in the furnace body 21 ( (Not shown) 'In order to limit the range of rotation of the dial 7 by limiting the thermal power', the second, third, and fourth long grooves ^ Buca and the second, third, and fourth communication paths 15b, 1Sc, It is consistent so that the gas amount in the gas outflow portion 16 becomes the largest. On the other hand, at a position 15 where the first long groove 62a coincides only with the first communication path 15a, a rotation preventing device 76 provided in contact with the protruding portion 56 at one end of the click-extinguishing button 5 is provided on the rotation guide path 75 (see Figures 6 (a) to 6 (e)). With this, in the valve opening position, the thermal power adjustment dial 7 can only minimize the gas flow rate toward the gas per outflow portion 16 and minimize the firepower of the gas burner 23 & It turns to the maximum to make the fire power of the gas burners 2023a and 23b freely rotate within the firepower adjustment range between the strong firepower, and one end of the rotation guide path 75 and the anti-rotation device 76 constitute a rotation range limiting device. Here, in order to allow the cook to easily adjust the firepower, for example, a taste of 14 1226422 may be generated at a position where the firepower of the gas burners 23a, 23b becomes weak and neutral. As shown in Figs. 3 (a) and 3 (b), a second protruding piece 54 opposed 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 54 having a smaller diameter than the first protruding piece 51 is provided in the hole 5 5 provided in the radial direction of the outer peripheral surface of the point-extinguishing button 5 in a state where 5 potential energy is applied outward in the radial direction by the spring 56. . Furthermore, at the predetermined positions of the rotation guide path 75, first and second recesses 77, 88 which are only capable of engaging the second protruding piece 54 in the radial direction are formed. Furthermore, when Lu Ru 'turned the thermal power adjustment dial 7 from the minimum flow rate (at this time, the thermal power of the gas burners 1023a and 23b is small), the second protruding piece 54 is engaged with the first recessed portion 77 when it is turned counterclockwise. , Can make a clicking sound. At this time, not only the first long groove 62a, but also the second long groove 62b and the second communication path 15b, which increases the gas flow rate toward the gas outflow portion 16 and weakens the firepower of the gas burners 23a, 23b. When the thermal power adjustment dial 7 is turned counterclockwise, a click sound is generated when the second recessed portion 78 is engaged with the 152th large output piece 54. At this time, not only the first and second long grooves 62b, but also the third long groove 62c and the third communication path 15c are increased, so that the gas flow rate toward the gas machine outlet 16 is increased, causing the gas burner]%, and the thermal power of the two to be reduced. Lu Chengzhong. Furthermore, a cam groove 73 is formed at the valve closing position of the point-extinguishing button 5 to enable 20 firepower. The dial 7 can be turned clockwise to exceed the firepower adjustment range. When the thermal power adjustment range is exceeded to turn the thermal power adjustment dial 7 to the end of the cam groove 73 and the pressing direction of the first protruding piece M with respect to the pressing direction of the operation button 5 formed at one end of the cam groove 73 is engaged with the right-angled wall portion 73a. Therefore, it is necessary to provide an additional operation section for the safety locking mechanism. Even if 15 1226422 is pressed from the valve closing position to the ignition position, the pressing button 5 cannot be moved, and the ignition device of the gas burner cannot be locked. position. In addition, when a safety locking mechanism is provided, it is preferable that the cook can easily recognize the role of safety locking. In the present embodiment, as shown in FIG. 7, at 5 j, each week is easy, and the main part of the fire adjustment dial 7 is provided with a window portion%, and a red mark is attached to a predetermined position of the rotating body 61. . Furthermore, if the fire power adjustment dial 7 is turned to the fine position, the red mark and the window portion 7a can be made to 0. Then the spear J will use the gas burner 23a to describe the operation of the gas control device 110 of the present invention. From the closed valve position i shown in FIG. 2, if the ignition button 5 is pressed, the firepower adjustment dial 7 can be rotated by the action of the first protruding piece 51 and the cam groove 73. At this moment, the suspected turning body 61 is rotated through the gear 72. At this position, the long grooves 62b, 62c, and 62d of the i, the second, and the third are connected to the respective communication paths 15b of the first, second, and third 15 , 15c, 15d, the fuel gas that can flow into the gas combustion state 2 3a toward the gas outflow portion 16 is the medium gas flow (see Figure 6 (d) 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 & 2 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. 16 1226422 If it is confirmed that the gas ignition ^ 23a is on fire and the pressing of the ignition button 5 is released, the ignition button 5 is guided to the open position shown in Fig. 9 by the heart-shaped cam mechanism%. 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 fire power adjustment dial 7 can rotate freely within the fire power adjustment range. In order to increase the fire power of the gas burner, if the ship ’s base 70 on the fire adjustment dial 7 is called the overhanging convex part from the middle fire position counterclockwise to engage the lock provided on the furnace body 21, the first 2. The 3rd and 4th long grooves 62b, 62c, and 62d will communicate with the 2nd, 3rd, and 4th communication channels 15b, 3b, and 4b, respectively, and the gas flow of the gas burner 23a is a strong gas flow. Fuel H) Gas flows toward the gas outflow portion 16 (see Fig. 6 (e) and Fig. 10 (a) and Fig.). On the other hand, in order to reduce the fire power of the gas burner 23a from the medium fire, if the second protruding piece 54 engages with the first! After the recess 77, turn the power adjustment dial 7 clockwise until ten clicks occur. Then, the long grooves in the second and the second, the 15 in the second and the communication paths 15a and 15b in the i and the second are the same, and the gas is the same. The fire power of the burner 为 is a weak gas flow and the fuel gas flows toward the gas (see Figure 6⑷ and Figures 3 (a) and 3 (b)). Then, if the firepower adjustment dial 7 is turned in the direction of the inch hand until the first protrusion 2 contacts the anti-rotation device 76 ′, then the first! Changgou—only the communication path with the ith… fuel with a minimum minimum gas flow rate for the gas combustion benefit 23a. The gas flows toward the gas outflow section M (see the figure for deduction and post) and Figure 6 (b)). When the gas burner 23a is extinguished, if the operating point extinguishing button 5 is pressed from the valve opening position in the backward direction, the heart-shaped cam mechanism 5b is reset, and the extinguishing button 5 17 1226422 receives the potential energy amount of the spring 5c and changes from the second The thermal power adjustment dial 7 shown in the figure is retracted to the protruding closed valve position. At this time, the control lever 4 whose pressing force is released by the push rod 5a is moved in the backward direction by the amount of potential energy provided by the impulse 34, and the main valve is closed. Once the main valve is closed, the supply of fuel gas to the gas burner 23a is stopped and the flame is stopped. If the controller recognizes that the flame has been extinguished by the flame detection device 26, the solenoid valve 3 is closed. After the table, in 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 and turn off the fire button 5 Cannot be pressed and locked by Safety10. Referring to Figs. 13 to 15, reference numeral 100 represents 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 is overflowed from a cooking appliance such as a pan during cooking, if the thermal power adjustment dial 7 is rotated in one direction, the gas burner 23 can be stopped. 2 Sun Zhiran 15 burned. At this time, a first protruding portion 501 having a substantially triangular cross section is formed at a predetermined position of the fire-extinguishing button 5, and corresponding to the protruding portion 501, a first protruding portion 501 is formed on the inner peripheral surface of the thermal adjustment dial 7 to project inward. 2projection 502. The second protruding portion 502 is formed so as to turn the power adjustment dial 7 clockwise at the valve opening position 20 of the point-extinguishing button 5 to abut against the first protruding portion 501 (Micui FIG. 15 (a)) . At this time, the first long hole 62a of the rotating body 161 coincides only with the first communication path 15a. Therefore, the second protruding portion 502 has an effect as a rotation stop device for the thermal power adjustment dial 7 for setting the minimum gas flow rate toward the gas outflow portion 16. 18 1226422 If the thermal adjustment dial 7 is rotated clockwise from the position where the second protrusion 502 abuts the first protrusion 501, the second protrusion 502 slides on the inclined surface 50a of the first protrusion 501 ( (See Figure 15 (b)). At this time, the fire button 5 is pushed forward, and when the second protrusion 502 passes through the inclined surface 501a of the first protrusion 501, the heart cam mechanism 5b is simultaneously reset (see FIG. 15 (c)). At this time, the flameout button 5 receives the force imparted by the potential energy of the spring 5c, and the flameout button 5 returns to the closed position (see FIG. 15 (d)). Therefore, in addition to pressing the operation point flameout button 5 to extinguish the gas burners 23a and 23b, each of the first and second protrusions 501 and 502 becomes a compulsory moving device for the flameout 10 button 5 so that the power adjustment dial 7 is directed toward Turning in the direction to extinguish the flames of the gas burners 23a and 23b can improve the convenience of gas conditioning appliances. However, in the first and second embodiments, although the 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 the belt power may be used to adjust the power adjustment. The dial 7 rotates in synchronization with the rotating body 61. Furthermore, as shown in Fig. 16, a motor 8 may be provided, and a rotating gear 81 attached to the motor may be coupled to the rotating body, and the rotating body 61 may be operated by turning the motor. As shown in Fig. 17 # 20, the gas burners 23a and 23b may not be ignited when the thermal power adjustment dial is operated to sharply reduce the gas flow. At this time, the second internal passage 12b between the gas flow outlet 14 and the flow control valve 6 is separated by a diaphragm 9 imparted with a potential energy in the direction of the gas flow outlet 14 by the spring 91 and flows out of the gas in the knife-opened chamber 92. There is a bypass 93 between the Guanguan gas exit 关 19 1226422. Diaphragm 9 is moved by the pressure difference between gas outlet 16a and gas outflow 卩 14 caused by the small gas flow of 115 in the heartland, and the fuel gas remaining in chamber 92 is supplied to the gas outlet shirt through the bypass 93 to prevent gas combustion The devices 23a and 23b caught fire. “Further,” as shown in FIG. 18, a speed regulating valve that matches the gas pressure of the fuel gas can also be provided between the gas flow outlet 14 and the flow regulating valve 6. It is possible to add a solenoid valve 210 separate from the solenoid valve 3 between the gas outlet U and the flow adjustment valve 6. 10 Advantageous Effects As described above, the gas control unit of the month is not required to be provided with a separate safety coffee operation unit, and In the _ position toward the-direction machine, the firepower adjustment dial can be turned by _ miscellaneous fire, so it can improve the convenience of the button, and can achieve the effect of reducing the number of parts and cost. 15 [Simplified illustration of the drawing] A perspective view of the gas furnace of the present invention.
