1231854 玖、發明說明： 【發明所屬之技術領域】 發明領域 本發明係有關於控制供給燃料瓦斯至設置於瓦斯爐等 5瓦斯調理器具上之瓦斯燃燒器的瓦斯控制裝置。 【先前技術]I 發明背景 這種瓦斯控制裝置，譬如已知有專利第2742356號公報 者。該瓦斯控制裝置具有，譬如，設置於瓦斯爐前面板， 於月〕後方向移動自如的點媳火按紐，在該點媳火按鈕前後 方向的不同二個位置處，設有開放保持連結瓦斯燃燒器的 瓦斯通路之開閥位置，作動瓦斯燃燒器點火裝置之點火位 置與閉鎖瓦斯通路之閉閥位置。 若從相對瓦斯爐之前面板大致設定在一面之閉閥位置 15按壓操作點熄火按紐，則點熄火按奴移動至點火位置，開 放瓦斯通路並且作動瓦斯燃燒器的點火裝置。如在確認瓦 斯燃燒器著火後釋放點媳火按姐之按壓，則點媳火按紐會 突出而移動至開閥位置。 在開閥位置¥，瓦斯燃燒器的火力調節係藉設置於點 2〇總火按姐周圍之環狀火力調節刻度盤進行。火力調節刻度 盤係設置於瓦斯通路，且與變化瓦斯通路之開口面積以調 即朝瓦斯燃燒燃料瓦斯的瓦斯流量之瓦斯流量調節裝置 連動。 欲停止瓦斯燃燒器的燃燒時，若壓人操作在開閥位置之 1231854 點媳火按域其移__位置，财闕瓦斯通路以使瓦 斯燃燒器熄火。 然而，上述者由於瓦斯燃燒器使用時，點熄火按祕 常從瓦斯爐的前面板突出，故，譬如，在烹調時溢出來的 5 $汁或來自-體設置於瓦斯爐之烤架的油煙等鱗污或垃圾 容易附著，有時會有湯汁順著點熄火按叙侵入瓦斯烹調器 具内，可能會使電路基板或開關等受到不良影響。 再者’若附著之垃圾原封不動，則當藉點熄火按知進 行熄火操作之際，會將垃圾帶入瓦斯爐内，與上述同樣， W會對電路基板或關閉等造成不良影響，或阻礙點媳火按钮 朝前後方向順暢地移動。 因此，雖點熄火按賴污就必須清潔，但由於為了使 點熄火按㈣侧壁位於突出位置，必須將點媳火按紐移動 至使用瓦斯燃燒器時之開閥位置，故必須進行瓦斯燃燒器 15之不必要的點火操作。 C發明内容3 發明概要 因此，鑑於上述點，本發明的課題在於提供一種在瓦 斯叉調器具使用中髒污或垃敗既難以附著於點媳火按紐， 20又能簡單的清潔點熄火按鈕之瓦斯控制。 為解決上述課題，本發明之瓦斯控制裝置包含有可在 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輯 火按紐，又，在該點熄火按紐的周圍，設置有在該點媳火 1231854 按紐的開閥位置可調節朝該瓦斯燃燒器燃料瓦斯供給量之 環狀火力調節刻度盤，其特徵在於：在前述閉閱位置，該 點總火按紐從瓦斯烹調器具的操作板突出，在從該閉_ 置壓入該點熄火按紐位置設有開閥位置。 5 根據本發明，在閉閥位置點熄火按叙從瓦斯烹調器具 的操作板突出。若從閉閥位置壓入操作點熄火按钮，職 斯通路開放而讓燃料瓦斯流動至瓦斯燃燒器，並作動點火 裝置。若藉點火裝置完成點火操作以解除點總火按紐的操 作，則點熄火按钮將會到達在開放狀態下保持瓦斯通路之 開閥位置。 此時，由於點媳火按紐由突出之位置壓入操作板側， 故點熄火按鈕的外周面成為隱藏在瓦斯烹調器具内之狀 怨。因此，即使在乂調時產生湯汁溢出，髒污也難以附著 於點媳火按姐，且湯汁將難以侵入瓦斯烹調器具内。 15 而且，若在火力調節範圍内轉動火力調節刻度盤，則 可增減供給至瓦斯燃燒器之燃料瓦斯的瓦斯流量以調節火 力。為熄滅瓦斯燃燒II，若操作點媳火独從_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。 20 在該熄火狀態下，由於點熄火按鈕從瓦斯烹調器具的 前面板突出，故若附著髒污或垃圾時’可完全不移動點熄 火按鈕就能進行其清潔。 在此，只要從瓦斯烹調器具的操作板突出設置前述火 力凋節刻度盤，則火力調節刻度盤成為點熄火按鈕的蓋 1231854 子，在使用瓦斯燃燒器時，可防止垃圾附著於點熄火按鈕 等。 而且，為使點熄火按鈕的清潔變得容易，以將點熄火 按4丑作成可自由拆裝為佳。 5 t實施方式】 較佳實施例之詳細說明 參閱第1圖，第1實施形態之瓦斯控制裝置i係組合於瓦 斯調理器具，譬如，瓦斯爐2中。此時，瓦斯爐2具有箱狀 的爐體21，在爐體21設有兩個瓦斯燃燒器23a、23b，且瓦 10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。 在爐體21前面兩端，設置有作為操作板之前面板24。 又，在爐體21上，設置有位於兩前面板24之間並設有陶瓷 板式燃燒器（未圖示）之烤架25。而且，藉本發明之瓦斯控制 15 裝置1，控制朝兩個瓦斯燃燒器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11a、lib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 20 ’並開設有連通第1内部通路12a之瓦斯流入部13。 位於瓦斯流入部13之下流側，在第1内部通路i2a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。 1231854 。亥吸附片連結由磁鐵箱31面向第丄内部通路似下流側 犬出之第1閥體32，在電磁閥3的閉閥狀態下，第丄闕體32藉 縮設於該第1閥體32與電磁箱31之間之彈簣33賦與勢能的 力量，透過密封材34a落座於設置於部通路12a之閥座 5 構造34之閥座中。 該電磁閥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 1〇置於第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設置於前面板 2 4之點熄火按鈕5來進行（參閱第i圖）。點熄火按鈕係呈圓筒 15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丨部份lla下側之 、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i内部通路12a之 2〇閉閥位置（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 1231854 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 操作而從開閥位置再壓入操作點熄火按叙5時，心形凸輪機 構5b復位回到熄火位置。 5 再者，在位於主閥上流側之第1部份11a設置瓦斯流出 口工4’該瓦斯流出口 14係與設置於第2部份llb之大致l字形 的第2内部通部121)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之外周面，隔著預定間隔相互隔絕地設 1〇置四個第^第2、第3及第4的各連通路15a、15b、15c、15d。 透過各連通路15a、15b、15c、15d，且連結在第2部份lib 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 15器23a、23b及在陶瓷板式燃燒器的各混合管喷射燃料瓦斯 之瓦斯噴嘴（未圖示)供給。此時，為調節朝瓦斯噴嘴之燃料 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 20的旋轉體61。在旋轉體161之外周面，四條圓周方向的第1、 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 10 1231854 成0 在此情形下，亦可使形成有通過各連通路15a、l5b、 15c、15d朝瓦斯流出部16流出之燃料瓦斯之瓦斯流量調節 為預疋里之西個節流孔口 63a、63b、63c、63d的孔口構件 5 63 ’與各連通路15a、15b、15c、⑸一致並安裝於第之部份 1 lb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、15c、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熄火按鈕5周 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7〇a安裝環狀蓋7〇b所構成。 火力調節刻度盤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llb突出的旋轉 15體61 一端部之齒輪72嚙合。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。 因此，將點熄火按鈕5設置於爐體21之前面板24時，由 ® 於在開閥位置點媳火按紐5從前面板24突出，譬如在烹調時 會產生之溢出來的湯汁或來自烤架25的油煙等髒污或垃圾 °會容易附著。此時，湯汁會順著點熄火按紐侵入瓦斯烹調 器具内，可能會使電路基板或開關等受到不良影響。 在本實施形態中，從前面板24突出設置火力調節刻度 盤7，並且在閉閥位置時，點熄火按鈕5從火力調節刻度盤7 的一端突出，若藉壓入操作將點熄火按鈕5移動至開閥位 11 1231854 置，則將使至少大部份之點熄火按鈕5外周面隱藏在火力調 節刻度盤7及前面板24内。 因此，在使用瓦斯燃燒器23a、23b時，由於點熄火按 鈕5外周面可利用火力調節刻度盤7及前面板24來遮蓋，故 5 可防止來自由溢出湯汁或烤架25之油煙等污染點熄火按鈕 5。又，也不會有湯汁順著點熄火按鈕5侵入瓦斯爐2内，使 電路基板或開關等受到不良影響之情形。 而且，由於在閉閥位置點熄火按姐5從火力調節刻度盤 7的一端突出，點熄火按鈕5及火力調節刻度盤7的清潔也很 1〇 得容易。 而且，只要不影響在閉閥位置點熄火按鈕5的壓入操 作’點熄火按鈕5前端與火力調節刻度盤7前端也可位於一 面上。 參閱第2圖至第11圖，在火力調節刻度盤7前方向内周 15 面形成凸輪溝73，且在火力調節刻度盤7内前後方向移動之 點熄火按鈕5外周面上設置有與凸輪溝73成對的第1突出片 51。此時，第1突出片51係藉彈簧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。 20 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 置’且可確實使燃料瓦斯著火之流量的燃料瓦斯可供給至 瓦斯燃燒器23a、23b。 12 1231854 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17之賦與勢能的力量，可簡化瓦斯 控制裝置之構造。 5 再者，凸輪溝73的壁面高度係形成為隨著點熄火按鈕5 的壓入操作從一方向另一方降低，而且，若從閉閥位置進 行點熄火按叙5的壓入操作，則隨著點媳火按紐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。 10 若再壓入操作點熄火按鈕5，則收納於前述孔52之第工 突出片51沿平坦部74移動到達點火位置。而且，作動放電 »又，點燃瓦斯燃燒器23a、23b之後，若解除點媳火按奴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。 15 _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，且沿著旋轉導引路75，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i突出片51未卡合凸輪溝乃。 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 2〇轉動，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6峰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^合設 置於爐體21之擋止(未圖示），以限制火力調節刻度盤7的旋 13 1231854 轉範圍，則第2、第3及第4之各長溝62b、61c、62d分別與 第2、第3及第4之各連通路i5b、15c、15d—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1連通路15a —致之位 5置處，將設置於點熄火按紐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(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 流出部16之瓦斯流量變成最小而使瓦斯燃燒器23a、23b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 10 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。 再者，在點熄火按鈕5之閉閥位置形成有凸輪溝73，使 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73 15 一端部，則第1突出片51相對形成於凸輪溝73—端部之操作 按钮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 從閉閥位置至點火位置按壓點熄火按鈕5也不能使其移 動，可形成瓦斯燃燒器之點火裝置不能作動之鎖固位置。 接著’利用瓦斯燃燒器23a說明本發明瓦斯控制裝置1 之動作。從第2圖所示閉閥位置，若施行點媳火按紐$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、 14 1231854 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 燃燒益23a的火力為中之瓦斯流量之燃料瓦斯（參閱第6(d) 圖及第10(a)與i〇(b)圖）。 5 若繼續點熄火按奴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 10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。 若確認瓦斯燃燒器23a已著火並解除點熄火按紐5的按 壓，則點熄火按鈕5受心形凸輪機構5b導引到達在第8圖所示 開閥位置。在開閥位置，點熄火按鈕5係被收納在火力調節刻 15 度盤7内。 此時，點熄火按鈕5之前端部由火力調節刻度盤7稍微突 出，又，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。 20 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70a外周壁之凸部從中火位置逆時針方向旋 轉到卡合设於爐體21之鎖扣’則第2、第3及第4之各長冓 62b、62c、62d將分別與第2、第3及第4之各連通路15卜15^、 15d-致，且瓦斯燃燒㈣a的火力為強的瓦斯流量之燃料 瓦斯朝瓦斯流出部16流動（參閱第6(e)圖及第 15 1231854 在另一方面，為從中火縮小瓦斯燃燒器23a的火力，若 順時針方向轉動火力調節刻度盤7，使第1及第2之各長溝 62a、62b分別與第1及第2之各連通路15a、15b—致，則瓦 斯燃燒器23a的火力為弱之瓦斯流量之燃料瓦斯朝瓦斯流 5動（參閱第6(c)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直到第工突 出片51接觸止轉裝置76，則第1長溝62a僅與第1連通路15a 一致’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16流動（參閱第ll(a)與11(b)圖及第6(b) 10 圖）。 媳滅瓦斯燃燒器23a時，若從開閥位置向後方向按壓操 作點媳火按鈕5，將使心形凸輪機構5b復位，且點熄火按鈕5 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。 15 此時，推桿5a的推壓被解除之操縱桿4承受彈簧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 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。 此外，在本實施形態中，雖然點熄火按鈕5固定於推桿 20 5a的一端，但為容易清潔點熄火按鈕5，也可將點熄火按鈕 5可自由拆裝地安裝於推桿5a上。 此時，如第12圖所示，譬如，只要在點熄火按鈕的推 桿5a之安裝部設置片簧5d即可。 再者’在本實施形態中，雖就在瓦斯爐前面板24設置 16 1231854 點熄火按鈕及火力調節刻度盤的情形加以說明，但也可在 烤爐、烤架等其他瓦斯烹調器具上使用具有點熄火按鈕及 火力調節刻度盤之本發明瓦斯控制裝置。 此外，譬如，在覆蓋爐體的頂板設置操作板之瓦斯爐 5亦適用具有點媳火按姐及火力調節刻度盤之本發明瓦斯控 制裝置。 如上所述，本發明之瓦斯控制裝置具有在瓦斯烹調器 具使用時髒污垃圾難以附著於點熄火按鈕，又可簡單地清 潔點熄火按鈕之效果。 10

belongs] Field of the invention The present invention relates to a gas control device for controlling the supply of fuel gas to a gas burner provided on a 5 gas conditioning appliance such as a gas furnace. [Prior Art] I Background of the Invention Such a gas control device is known, for example, from Japanese Patent No. 2742356. The gas control device is provided with, for example, a beacon button which is provided on the front panel of the gas furnace and can move freely in the rear direction. At the two different positions in the forward and backward directions of the beacon button, there is an open and maintained gas connection. The valve opening position of the gas passage of the burner, the ignition position of the ignition device of the activated gas burner and the valve closing position of the closed gas passage. If the front panel of the relative gas furnace is set to the closed valve position on one side, and the operating button is pressed, the ignition 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 of the gas burner is released after confirming that the gas burner is on fire, press the button of the flame, the button of the flame fire will protrude and move to the valve opening position. In the valve opening position ¥, the firepower adjustment of the gas burner is performed by setting a ring-shaped firepower adjustment dial around the total fire at point 20. The fire power adjustment dial is provided in the gas passage, and is linked with a gas flow adjustment device that changes the opening area of the gas passage to adjust the gas flow of fuel gas burning toward the gas. If you want to stop the combustion of the gas burner, if you press and operate at the valve opening position of 1231854, the flame will be moved to the __ position according to the domain, and the gas passage will be used to stop the gas burner. However, the above-mentioned ones often protrude from the front panel of the gas stove when the gas burner is in use, so, for example, 5 $ juice that overflows during cooking or oil fume from the grill set on the gas stove Scaling or garbage is easy to adhere, and sometimes the soup will be turned off and then intruded into the gas cooking appliance, which may adversely affect the circuit board or switch. Furthermore, if the attached garbage is left intact, when the point is turned off to perform the flameout operation according to the knowledge, the garbage will be brought into the gas furnace. As above, W will adversely affect the circuit board or shut down, or hinder it. Click the fire button to move forward and backward smoothly. Therefore, although it is necessary to clean the flame-out and the contamination, it is necessary to move the flame-release button to the valve-opening position when the gas burner is used in order to make the flame-out wall of the flame-out. Unnecessary ignition operation of the device 15. C Summary of the Invention 3 Summary of the Invention Therefore, in view of the foregoing, an object of the present invention is to provide a dirt or garbage which is difficult to attach to a fire button during use of a gas fork adjusting device, and can also simply clean a fire button. Gas control. In order to solve the above problems, the gas control device of the present invention includes an ignition button that can move freely in the forward and backward direction between an open position that keeps a gas passageway connected to a gas burner open and a valve closing position that locks the gas passageway. Also, around the flameout button at this point, a ring-shaped firepower adjusting dial capable of adjusting the gas supply amount to the gas burner at the valve opening position of the button 1231854 at that point is provided, which is characterized in that: In the aforementioned closed reading position, the general fire button at this point protrudes from the operation panel of the gas cooking appliance, and a valve opening position is provided at the flame-out button position pressed into the point from the closed position. 5 According to the present invention, the flameout at the valve closing position protrudes from the operation panel of the gas cooking appliance as described. If the operating point flameout button is pushed in from the closed position, the job passage is opened to allow fuel gas to flow to the gas burner, and the ignition is activated. If the ignition operation is completed by the ignition device to release the operation of the ignition button, the ignition button will reach the valve opening position to maintain the gas passage in the open state. At this time, since the ignition button is pushed into the operation panel side from the protruding position, the outer peripheral surface of the ignition button is hidden in the gas cooking appliance. Therefore, even if the soup overflows during the cooking process, it is difficult for dirt to adhere to the lighter, and the soup will hardly penetrate into the gas cooking appliance. 15 Moreover, if the power adjustment dial is turned within the power adjustment range, the gas flow of the fuel gas supplied to the gas burner can be increased or decreased to adjust the power. In order to extinguish gas combustion II, if the operating point of the beacon is moved from the _ position to the valve closing position alone, the gas passage is blocked to stop supplying gas to the gas burner. 20 In this flameout state, the ignition off button protrudes from the front panel of the gas cooking appliance, so if dirt or garbage is attached, it can be cleaned without moving the ignition off button at all. Here, as long as the aforementioned firepower withdrawing dial is protruded from the operation panel of the gas cooking appliance, the firepower adjusting dial becomes a cover 1231854 for the light-off button. When the gas burner is used, it is possible to prevent garbage from attaching to the light-off button. . In addition, in order to make cleaning of the flameout button easy, it is better to make the flameout button freely detachable. 5t embodiment] Detailed description of the preferred embodiment Referring to Fig. 1, the gas control device i of the first embodiment is incorporated in a gas conditioning appliance, such as a gas furnace 2.

Further, the furnace body 21 is provided with a grill 25 provided between the two front panels 24 and provided with a ceramic plate burner (not shown). The gas control 15 device 1 of the present invention controls the supply of fuel gas to the two gas burners 23a, 23b and the ceramic plate burner. Referring to Fig. 2, the gas control device 1 has a valve housing composed of two portions 11a, lib which are connected to each other in an overlapping manner. The first portion 11a of the valve housing on the lower side is provided with a first internal passage 20 'extending in the longitudinal direction of the valve housing, and a gas inflow portion 13 communicating with the first internal passage 12a is provided. Located on the downstream side of the gas inflow portion 13, a solenoid valve 3 is provided in the first internal passage i2a. The solenoid valve 3 includes a magnet case 31, and the magnet case 31 accommodates, for example, an electromagnet excited by a signal from a control device (not shown) provided in the furnace body 21 and an adsorption sheet adsorbed by the electromagnet. 1231854. The first suction body 32 is connected to the first valve body 32 which faces out from the magnet box 31 toward the first internal passage like the downstream side. In the closed state of the solenoid valve 3, the third body 32 is contracted and provided on the first valve body 32. The impulse 33 between the electromagnetic box 31 and the potential-giving force is seated in the valve seat of the valve seat 5 structure 34 provided in the partial passage 12a through the sealing material 34a. The opening operation of the solenoid valve 3 is performed by a joystick 4 which is inserted into the first internal passage 12a via a sealing material 41 and is movable back and forth along the longitudinal direction of the first internal 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. In the closed state 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 a push-in operation of a point-off button 5 provided on the front panel 24 (see FIG. I). The light-off button is in the shape of a cylinder 15, and on the end surface of the first internal passage 12a side, the pusher 5a of the joystick 4 can be connected with the movement of the light-off button 5 '. Furthermore, one end of the push rod 5a is connected to a cam mechanism 5b provided on the lower side of the first portion 11a. At this time, if the operation point extinction button 5 is pushed in, the ignition operation is started by protruding from the top surface of the power adjustment dial described later and closing the 20th valve closing position of the i-th internal passage 12a (the state shown in FIG. 1). Then, the lever 4 is pushed to the rear (right side of Fig. 2) through the push rod 5a to open the main valve, and 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 Actuated ignition position. If the pressing of the flameout button 5 is released from the ignition position, it is guided by the heart-shaped cam 1231854 mechanism 5b to move forward (left side of FIG. 2), and then the main valve is kept open to reach the opening state of the first internal passage 12a. position. To perform the flame-out operation, when the valve-opening position is pressed into the operating point and the flame-out is pressed, the heart-shaped cam mechanism 5b is reset to the flame-out position. 5 Furthermore, a gas flow outlet 4 'is provided in the first portion 11a located on the upstream side of the main valve. The gas flow outlet 14 is connected to the second internal communication portion 121 of a substantially l-shape provided in the second portion 11b. One end is consistent, and each of the first and second internal passages 12a and 12b constitutes a gas passage. On the outer peripheral surface of the second part lib, four communication paths 15a, 15b, 15c, and 15d of the second, second, third, and fourth are provided in isolation from each other at predetermined intervals. The gas outflow portion 16 connected to the upper portion of the second portion lib through each of the communication paths 15a, 15b, 15c, and 15d communicates with the second internal passage 12b. At this time, the apertures of each of the continuous passages 15a, 15b, 15c, and 15d are gradually increased toward the front and formed. Further, the fuel gas flowing from the gas outflow portion 16 is supplied to the gas burners 15a, 23b, and a gas nozzle (not shown) that injects fuel gas into each mixing tube 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 rotary body 61 having a cylindrical shape 20 provided in the second internal passage 12b so as to be rotatable through a sealing material 61a. On the outer peripheral surface of the rotating body 161, four first, second, third, and fourth long grooves 62a, 62b, 62c, and 62d in the circumferential direction correspond to the first, second, third, and fourth consecutive grooves, respectively. The passages 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 shape 10 1231854 to 0. In this case, it is also possible to make The gas flow rate of the fuel gas flowing toward the gas outflow portion 16 through each of the communication paths 15a, 15b, 15c, and 15d is adjusted to the orifice members 5 63 ′ of the western throttle orifices 63 a, 63 b, 63 c, and 63 d of the pre-airline. Each of the communication paths 15a, 15b, 15c, and ⑸ are aligned and installed on the outer peripheral surface of the first part 1 lb. Then, the rotating body 61 is rotated so that each of the long grooves 62a, 62b, 62c, and 62d and the communication paths 15a, 15b, 15c, and 15d are appropriately matched, and the gas flow rate of the fuel gas flowing toward the gas outflow portion 16 can be adjusted. The adjustment of the rotation angle of the rotating body 61 is performed by using the thermal power adjustment dial 7 provided around the turning-off button. As shown in Fig. 4, the thermal power adjustment scale 7 is formed by mounting a ring-shaped cover 70b on a hollow cylindrical base 70a. The end of the first internal passage 11a of the thermal power adjustment dial 7 is cut with a predetermined pitch, and the cut portion 71 is engaged with a gear 72 fitted at one end of the rotating 15 body 61 protruding from the second portion 11b. Therefore, the rotating body 61 rotates in synchronization with the rotation operation of the thermal power adjustment dial 7. Therefore, when the light-off button 5 is set on the front panel 24 of the furnace body 21, the flame button 5 is protruded from the front panel 24 at the valve opening position, such as the overflowing soup or cooking from the grill during cooking. Dirt or garbage such as oil fume of the rack 25 will easily adhere. At this time, the soup will enter the gas cooking appliance along the flameout button, which may adversely affect the circuit board or switch. In this embodiment, the fire adjustment dial 7 is protruded from the front panel 24, and when the valve is closed, the flameout button 5 is protruded from one end of the fire adjustment dial 7. If the push-in operation is performed, the fireout adjustment button 5 is moved to When the valve opening position 11 1231854 is set, at least most of the point of the flameout button 5 is hidden in the fire adjustment dial 7 and the front panel 24. Therefore, when the gas burners 23a and 23b are used, the outer peripheral surface of the turning-off button 5 can be covered by the power adjustment dial 7 and the front panel 24, so 5 can prevent pollution from overflowing the soup or the oil fume from the grill 25. Click the flameout button 5. In addition, the soup does not intrude into the gas furnace 2 along with the turn-off button 5 and adversely affects the circuit board, the switch, and the like. In addition, since the flame-out button 5 is protruded from one end of the thermal adjustment dial 7 at the valve closing position, cleaning of the flame-out button 5 and the thermal adjustment dial 7 is also easy. Further, as long as the pressing operation of the flameout button 5 at the valve closing position is not affected, the front end of the flameout button 5 and the front end of the thermal adjustment dial 7 may be located on one side. Referring to FIGS. 2 to 11, a cam groove 73 is formed on the inner periphery 15 surface of the front side of the thermal adjustment dial 7, and a cam groove is provided on the outer peripheral surface of the flameout button 5 at a point where the thermal adjustment dial 7 moves forward and backward. 73paired first protruding piece 51. 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 flameout button in a state where potential energy facing the outside in the radial direction is imparted by the spring 53. 20 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 scale formed by the cam groove 73 of the passive section is adjusted. Fuel gas, which can rotate the disk 7 to a predetermined position, and which can surely cause the fuel gas to ignite, can be supplied to the gas burners 23a, 23b. 12 1231854 At this time, since the point-extinguishing button 5 is pressed to turn the power adjustment dial 7 by the pressing operation, for example, it is not necessary to increase the size of the spring 17 retracted between the point-extinguishing button 5 and the first part 11a. Potential energy can simplify the structure of the gas control device. 5 Furthermore, the height of the wall surface of the cam groove 73 is formed to decrease from one direction to the other as the push-in operation of the point-extinguishing button 5 is performed. The moving first protruding piece 51 with the ignition button 5 is housed in the hole 52 and reaches the flat portion 74 extending from the cam groove 73 in the longitudinal direction. 10. When the operating point flameout button 5 is pushed in again, the first protruding piece 51 stored in the hole 52 moves along the flat portion 74 to the ignition position. Furthermore, when the electric discharge is activated, and after the gas burners 23a and 23b are ignited, if the pressing of the ignition 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 Click the flameout button 5 to reach the valve opening position. 15 _ The valve opening position should be on the inner peripheral surface of the thermal adjustment dial 7 to form a rotating guide path 75 on the same plane as the flat portion 74, and along the rotational guide path 75, the thermal adjustment dial 7 can be clockwise Or rotate freely counterclockwise. At this time, the i-th protruding piece 51 received in the hole 52 is not engaged with the cam groove. Further, if the rotating body 61 is rotated so that the thermal power adjustment dial 7 is rotated clockwise 20, the gas flow rate is reduced, and if it is rotated counterclockwise, the gas flow rate is increased. At this time, the peak of the rotating body 6 is arranged to rotate counterclockwise to a convex portion (not shown) provided on the outer peripheral wall of the base portion 70a of the thermal adjustment dial 7 (not shown) and a stop (not shown) provided on the furnace body 21, The range of rotation 13 1231854 of the rotary dial 7 is adjusted to limit the firepower. Then, the second, third, and fourth long grooves 62b, 61c, and 62d and the second, third, and fourth communication channels i5b, 15c, and 15d, respectively. -Make the gas amount at the gas outflow portion 16 maximize. On the other hand, at the position 5 where the first long groove 62a is only connected to the first communication path 15a, it will be installed at the point where the flameout button 5 is placed. The anti-rotation device 76 contacted by the protruding portion 56 is provided in the rotation guide path 75 (see FIGS. 6 (a) to 6 (e)). With this, in the valve opening position, the thermal power adjustment dial 7 can The firepower between the gas flow rate of the gas outflow portion 16 being minimized to make the firepower of the gas burners 23a, 23b small and the strong firepower that maximizes the gas flow rate and make the firepower of the gas burners 10 23a, 23b to be strong Rotate freely within the adjustment range. Moreover, a cam groove 73 is formed at the valve closing position of the ignition button 5 to adjust the fire power. The dial 7 can be rotated clockwise to exceed the thermal adjustment range. If the thermal adjustment range is exceeded to turn the thermal adjustment dial 7 to one end of the cam groove 73 15, the first protruding piece 51 is formed relatively to the cam groove 73-end. The pressing direction of the operation button 5 engages the right-angled wall portion 73a. Therefore, there is no need to provide an additional operation portion for the safety lock mechanism, and even if the flameout button 5 is pressed from the valve closing position to the ignition position, it cannot be moved, and gas can be formed. The locked position where the ignition device of the burner cannot be operated. Next, the operation of the gas control device 1 of the present invention will be described using the gas burner 23a. From the valve closing position shown in FIG. Then, 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 in this position, the i, 14 1231854 second and third Each of the long grooves 62b, 62c, and 62d is connected to each of the first, second, and third communication paths 15b, 15c, and 15d, respectively, and can flow into the gas outflow portion 16 into the gas combustion benefit 23a. The fuel gas has a medium gas flow and fuel gas. (Refer to Figure 6 (d) and Figures 10 (a) and i〇 (b).) 5 If you continue to press the flame off button 5 as shown in Figure 8, you can go back through the pusher 5a Press the operating lever 4 to open the main valve, and reach the ignition position that pushes the valve body 32 to the side of the suction plate. Once the ignition position is reached, the ignition operation of the gas burner 23a is performed by the discharge setting. Moreover, once it is set to the gas burner 23a The nearby flame 10 detection device 26 (see FIG. 1) detects the flame of the gas burner 23 a, that is, the signal from the control device excites the solenoid valve and keeps it open. When 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 to the valve opening position shown in Fig. 8 by the heart-shaped cam mechanism 5b. In the valve opening position, the flameout button 5 is stored in the thermal adjustment dial 7. At this time, the front end of the fire button 5 is slightly protruded by the fire adjustment dial 7, and the main valve 6 is kept open by the push of the joystick 4. At the same time, the fire adjustment dial 7 can be turned within the fire adjustment range. freely. 20 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 second The 3rd and 4th long 冓 62b, 62c, 62d will be connected to the 2nd, 3rd, and 4th connecting roads 15b, 15 ^, 15d, respectively, and the firepower of the gas combustion ㈣a is a strong gas flow. The fuel gas flows toward the gas outflow portion 16 (see FIG. 6 (e) and 15 1231854. On the other hand, in order to reduce the fire power of the gas burner 23a from medium fire, if the fire power adjustment dial 7 is turned clockwise, the first Each of the long grooves 62a and 62b of the 1st and the 2nd are in agreement with the respective communication paths 15a and 15b of the 1st and the 2nd, respectively, and the fire power of the gas burner 23a is a weak gas flow. Figure 6 (c) and Figures 3 (a) and 3 (b)). Then 'If the fire adjustment dial 7 is turned clockwise until the first projecting piece 51 contacts the anti-rotation device 76, the first long groove 62a is only connected with The first communication path 15a is the same, and the gas power of the gas burner 23a is small and the minimum gas flow is the gas flow toward the gas. Part 16 flows (see Figures ll (a) and 11 (b) and Figure 6 (b) 10). When the gas burner 23a is extinguished, if the operating point fire button 5 is pressed backward from the valve opening position, the The heart-shaped cam mechanism 5b is reset, and the light-off button 5 receives the potential energy of the spring 5c, and moves backward from the thermal adjustment dial 7 shown in FIG. 2 to the protruding valve closing position. 15 At this time, the Pressing the released lever 4 moves in the backward direction in response to the energizing force of the spring 34, and closes the main valve. Once the main valve is closed, the gas supply to the gas burner 23a is stopped and the flame is turned off. If the controller recognizes By the flame detection device 26, the flame is turned off, and the solenoid valve 3 is closed. In addition, in this embodiment, although the flameout button 5 is fixed to one end of the push rod 20 5a, the flameout button 5 can be easily cleaned. The light-off button 5 is detachably mounted on the push rod 5a. At this time, as shown in FIG. 12, for example, a leaf spring 5d may be provided on the mounting portion of the light-off button push rod 5a. In this embodiment, although the gas furnace front panel 24 is provided with 16 1231854 The case of turning off the flame button and the power adjustment dial will be described, but the gas control device of the present invention having the turning off button and the power adjustment dial may be used on other gas cooking appliances such as an oven or a grill. In addition, for example, in The gas furnace 5 provided with an operation panel on the top plate of the furnace body is also applicable to the gas control device of the present invention, which has a light-burning button and a power adjustment dial. As described above, the gas control device of the present invention is dirty when the gas cooking appliance is used.
