C 明 屬 領 J 發明領域 本發明係有關於控制朝設於如瓦斯爐之瓦斯燃燒器之 燃料瓦斯供給的瓦斯控制裝置。 C先前技 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， 於前後方向移動自如的點熄火按鈕，在該點熄火按鈕前後 方向的不同三個位置處，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。 若從閉閥位置按壓操作點熄火按鈕，則點熄火按鈕移 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熄火按鈕之按 壓’則點熄火按鈕會突出而移動至開閥位置。 在開閥位置時，瓦斯燃燒器的火力調節係藉設置於點 媳火按紐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 節朝瓦斯燃燒器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，若壓入操作在開閥位置之 點熄火按鈕使其移動到閉閥位置，則可閉鎖瓦斯通路以使瓦 斯燃燒器熄火。 在此，瓦斯燃燒器點火操作時，為確實使燃料瓦斯著 火’譬如，宜㈣料請供給至瓦斯職n之混合管，使 瓦斯燃燒器的火力變成強火或中火。 因此，在前述瓦斯控制裝置中設有復位機構，該復位 機構在熄滅瓦斯職ϋ之際，與其點熄火按域壓入操作 連動’使火力調㈣度盤_轉魅使火力㈣刻度盤 復位到瓦斯燃燒器火力變強的位置。 上述者，由於設有復位裝置，在點減火按鈕的閉閱位 置不能轉動火力調節刻度盤。 發明欲解決之課題 …王饰斤點烬X按紐之際，藉 使用如凸輪機構之強制旋財置_地轉動火力調節刻^ 盤’使瓦斯燃燒器的火力變成強或中，且在點媳火按紐的 閉閥位置時，使火力調節刻度盤可旋轉自如。 可是’如僅設有強制旋轉裝置，則在開閱位置轉動火 7即刻度盤以調節火力時’若強制旋轉袈置位於扣合狀 L，則火力調節刻度盤之操作性會變差，可能會對烹調者 之旋轉操作感產生不良影響。 因此本發私於上述點，其課題在於提供—種在瓦 Ρ燒器之關位置進行火力_時，不會影響旋轉操作 感之瓦斯控制裝置。 C發明内容3 為解決課題之手段 為解決上述課題，包含有在前後方向㈣自如之點媳 、、〜a在該點媳火按紐的前後方向上m有閉鎖連 通瓦斯燃燒器之瓦斯通路之閉閥位置與保持該瓦斯通路開 放之開閥位置，且在該點熄火按紅的周圍，設置可調節朝 j瓦斯燃燒器之燃料瓦斯供給量以調節火力之環狀火力調 郎刻度盤，其特徵在於：點火操作係藉由前述點熄火按紐 的壓入操作從別述閉閥位置移動至前述開闕位置來構成， 又，=瓦斯控制裝置設置有強制旋轉裝置，該強制旋轉裝 置與前述點媳火按缝前述賴位置到前述關位置之麼 入操作連動，並強制地轉動前述火力調節刻度盤，使瓦斯 燃燒器之火力變成—定火力’而以該強制旋轉裝置造成前 述火2調節刻度盤之強制旋轉係在點媳火按紐到達開閥位 置之前結束，且在前述開閥位置時，可解除在前述點媳火 按紐與别述火力调節刻度盤之間藉由前述強制旋轉裝置所 產生之扣合關係。 根據本發明，當為了進行點火操作而從閉閥位置廢入 操作點熄火按㈣，則瓦斯通路開放且婦瓦斯流至瓦斯 燃燒器。在此情形下，藉強織轉裝置可_轉動火力調 郎刻度盤。點火操作結束時，點熄火按蝴相閥位置。 此時，火力調節刻度盤已經轉動至位置，並且瓦斯通 路保持開放。 若在點熄火按鈕的開閥位置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瓦 斯燃燒器的火力。此時，由於可解除藉點熄火按叙與火力 1221892 調節刻度盤之間的強制旋轉袈置所產生之扣合關係，不但 不曰損口火力肩節刻度盤之操作性，亦不會對烹調者之轉 動操作感產生不良影響。 右為:L滅瓦斯燃燒器而將點炮火按钮從開闊位置移動 至閉閥位Ϊ貞彳瓦斯通路關以停止朝瓦斯燃燒器供給燃 料瓦斯。 在此車又佳地，則述強制旋轉裝置由設置於位在前述 點總火按纽外周面之半控方向之孔中並朝外側賦與勢能之 犬出片’與叹置於别述火力調節刻度盤内周面之凸輪所構 成又Ik著月，j述點熄火按紐從前述閉閥位置朝前述開闕 位置之移動’讀突出片被收納於前述孔内並離開凸輪 溝，並在開閥位置時，前述突出片與前述凸輪溝不再扣合。 I：實施方式;3 發明之實施形態 15 參閱第1圖，瓦斯控制裝置1係組合於，譬如，瓦斯爐2 中。此時’瓦斯爐2具有箱狀的爐體2卜在爐體21設有兩個 瓦斯燃燒裔23a、23b，且瓦斯燃燒器23a、2儿面臨設置於 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 20之間的烤架25，且烤架25設置有陶究板式燃燒器（未圖示）。 而且，藉本發明之瓦斯控制裝置卜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所構成的間殼體。在位於下側之間殼體 8 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，在第丨内部通路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，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。 忒吸附片連結由磁鐵箱31面向第1内部通路i2a下流側 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之間之彈簧33賦與勢能的 力里，透過雄、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。 該電磁閥3的開閥操作係藉由隔著密封材41插設於第j 内部通路12a，並沿著帛丨内部通路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43一同構成主閥。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 出設置之點熄火按紐5來進行(參閱第lg|)。點熄火按紐係呈 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-端料結設置於第㈣份山下側之 心形凸輪機構5b。此時，若壓人操作點熄火按奶以由從後 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推開至吸附片侧，且點火裝置之放電設備（未圖示） 5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 操作而從開閥位置再壓入操作點熄火按鈕5時，心形凸輪機 10構5b復位回到熄火位置。 再者，在位於主閥上流側之第丨部份11a設置瓦斯流出 口 14,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。 15 在第2部份11b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、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。 20 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 之瓦斯喷嘴（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61 a旋轉自如地設置於第2内部通路i2b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、02b、62c、02d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。 此外，在本實施形態，使形成有通過各連通路15a、 15b、15c、15d朝瓦斯流出部16流出之燃料瓦斯之瓦斯流量 調卽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、15b、15c、15d一致並安裝於第2 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、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内部通路丨la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 體61—端部之齒輪72嚙合。因此，旋轉體“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 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 1221892 佳0 再者’考慮到安全性’以設有小孩等誤觸點媳火按紐5 而放電設備不能作動之所謂的安全咖機構為佳。 參閱第2圖至第6⑷至6(e)圖，在本實施形態中，在自 5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内之麟火餘周面上設置與凸輪溝咖對之第 1突出片51以構成強制旋轉|置。此時，第丨突出片51係藉 彈簧S3賦與面向半徑方向外側勢能的狀態下，設置在設於 10點總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 置。 15 此時，由於係利用點熄火按钮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。 可是，在開閥位置轉動火力調節刻度盤7以調節火力 20時’由於突出片51與凸輪溝73發生干涉，故火力調節刻度 盤7的操作性變差，可能會對於烹調者的旋轉操作感產生不 良之影響。 在本實施形態，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 12 1221892 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5 ’且到達從凸輪 溝73朝縱向延伸之平坦部74。 若再壓入操作點熄火按钮5，職納於前述孔％之第i 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1123a、23b之後，若解除點熄火按钮㈣ 按壓，則受心形凸輪機構5b導引而藉彈簧〜賦與勢能的力 量稍微回位，且點熄火按鈕5到達開閱位置。 10 對應開閥位置在火力調節 部74同一平面的旋轉導引路75 刻度盤7内周面，形成與平坦 ’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。 藉此，藉由連動自閉閥位置朝開閥位置之點媳火按紐5 之壓入操作的W突出片51與凸輪溝73之強制旋轉裝置，所 15 達點火位置之前結束’且在開閥位置時可解除祕火按紐5 的突出片51與火力調節刻度盤7的凸輪溝乃之扣合。 而且，若旋轉旋轉體61以使火力調節刻度盤7朝順時針 20 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之擔止（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62b、61c、62d分別與 13 1221892 第2、第3及第4之各連通路15b、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 5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2%、2扑的 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 10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 咔嗒聲。 15 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i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 勢月b的狀態下設置在設於點熄、火按盤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的半徑方向之第丨及第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 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， 14 1221892 長溝62b亦與第2連通路15b—致而增加朝瓦斯流出部μ 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 2大出片54卡合則發生咔嗒聲。此時，不但第丨及第2長溝 5 62a、62b，第3長溝62c亦與第3連通路15c—致而增加朝瓦斯 流出部16之瓦斯流量增加，使瓦斯燃燒器23a、23b的火力變 成中。 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 10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 、4則第1突出片51相對形成於凸輪溝73 —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 從閉閥位置至點火位置按壓點熄火按鈕5也不能使其移 15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說明本發明之瓦斯裝置！之 動作。從第2圖所示閉閥位置，設進行點熄火按鈕5的壓入 操作，則由第1突出片51與凸輪溝73之作用可轉動火力調節 刻度盤7。 在此’第7圖顯示瓦斯燃燒器23a的火力在弱的位置被 熄火之後，操作點熄火按鈕5進行點火操作時火力調節刻度 盤7之作動例。 若壓入操作點熄火按鈕5，則操作按紐5之突出片51抵 接凸輪溝73。如抵接凸輪溝73，則可隨著點熄火按鈕5的移 15 1221892 動來轉動火力調節刻度盤7。依此，第1突出片51一邊被收 納於前述孔52内，一邊到達從凸輪溝73縱向延伸之平坦部 74 〇 此時，旋轉體61係透過齒輪72旋轉，在該位置，第i、 5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6(d) 圖及第11(a)與11(b)圖）。 右繼續點媳火按知5的按壓操作，如第8圖所示，則可 1〇透過推桿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 檢出器件26(參閱第1圖）檢出瓦斯燃燒器23a的火焰，即以來 15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鈕5的按 壓，則點熄火按紐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。 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 轉到卡合設於爐體21之鎖扣，則第2、第3及第4之各長溝 621)、62〇、62〇1將分別與第2、第3及第4之各連通路15卜15。、 15d—致，且瓦斯燃燒器23a的火力為強的瓦斯流量之燃料 16 瓦斯朝瓦斯流出部b流動（參閱第6(e)圖及第10⑷與释) 圖）。 另-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i凹部77後再順時針方向轉動火力調節刻 度盤7直到發生味塔聲，則第i及第2之各長;f62a、62b分別 與第1及第2之各連通路15a、15b—致，且瓦㈣燒器^的 火力為弱之瓦斯流量之燃料瓦斯朝瓦斯流動(參閱第S⑷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直到第丨突出 1〇片51接觸止轉裝置76，則第1長溝62a僅與第丨連通路15a一 致’且瓦斯燃燒H23a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 15承受彈簧允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 20器辨認藉火焰檢出器件26火焰已熄，則關閉電磁閥3。 最後’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1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 鎖固。 17 此外，在本實施形態中，壓入操作點熄火按鈕5進行點 火操作時，雖係藉由強制旋轉裝置使火力調節刻度盤7可轉 動到瓦斯燃燒器23a、23b的火力為中之位置，但並非限定 如此。 譬如，如在第13(a)圖所示，凸輪溝73係亦可構成為使 火力調節刻度盤7可轉動到瓦斯燃燒器23a、23b的火力為強 的位置。 再者，如在第13(b)圖所示，亦可當即將熄滅瓦斯燃燒 器23a、23b之前，在火力調節刻度盤7位於火力為強之位置 的情形下，當進行下一個點火操作之際，依原狀態進行點 火操作，且僅在較火力為中之位置火力更小的一側處，瓦 斯燃燒器23a、23b欲總火時，使火力調節刻度盤7可轉動到 瓦斯燃燒器23a、23b的火力成為中的位置。 發明效果 如上所述，本發明之一種瓦斯控制裝置具有不僅不會 不損害火力調節刻度盤的操作性，而且可防止對烹調者之 旋轉操作感產生不良影響的效果。 【圖式簡翠《說^明】

a gas burner such as a gas furnace. C Prior Art Background of the Invention Such a gas control device is known, for example, from Japanese Patent No. 2742356. The gas control device includes, for example, a point flameout button provided on the front panel of the gas furnace, which can move freely in the front-rear direction, and at three different positions in the front-rear direction of the point flame-out button, a gas passage which is open and connected to the gas burner is provided. The valve opening position is the ignition position of the ignition device of the gas burner and the valve closing position for closing the gas passage. When the operating point flameout button is pressed from the valve closing position, the flameout button is moved to the ignition position, the gas passage is opened, and the ignition device of the gas burner is activated. If the ignition button is released after confirming that the gas burner is on fire, the ignition button will protrude and move to the valve opening position. In the valve-open position, the firepower adjustment of the gas burner is performed by a ring-shaped firepower adjustment dial set around the ignition button. 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 toward the gas burner fuel gas. If you want to stop the combustion of the gas burner, if you press the stop button at the point where the valve is opened to move it to the closed position, you can lock the gas passage to stop the gas burner. Here, during the ignition operation of the gas burner, in order to surely ignite the fuel gas, for example, it is advisable to supply it to a mixing pipe of the gas burner, so that the firepower of the gas burner becomes strong or medium. Therefore, a reset mechanism is provided in the aforementioned gas control device. When the gas position is extinguished, the reset mechanism is linked with its point-out operation and press-in operation according to the range to reset the fire control dial_turning charm to reset the fire control dial to The position where the gas burner becomes stronger. In the above, since the resetting device is provided, the firepower adjustment dial cannot be turned in the closed reading position of the fire reduction button. The problem to be solved by the invention ... While Wang Xingjin embers the X button, by using a forced rotation of the cam mechanism to turn the fire power to adjust the engraving plate ^, the fire power of the gas burner becomes strong or medium, and at the point When the fire button is in the closed valve position, the power adjustment dial can be rotated freely. However, 'if only the forced rotation device is provided, when the fire 7 is turned in the open position, that is, the dial is adjusted to adjust the firepower', if the forced rotation setting is located in the snap-shaped L, the operability of the firepower adjustment dial may be deteriorated, and It will adversely affect the rotating operation feeling of the cook. Therefore, this issue is private to the above point, and its problem is to provide a gas control device that does not affect the sense of rotation operation when the firepower is performed at the off position of the tile burner. C. Summary of the Invention 3 Means for solving the problem To solve the above-mentioned problem, it includes the point of freedom in the front-rear direction 媳, ~ a at the point of the fire button in the front-rear direction of m, which has a gas passage that is connected to the gas burner. A valve-closing position and a valve-opening position that keeps the gas passage open, and a ring-shaped firepower adjusting dial that can adjust the amount of fuel gas supplied to the j gas burner to adjust the firepower is set around the point where the flame is turned off. It is characterized in that the ignition operation is constituted by moving the aforementioned point-extinguishing button from the other valve closing position to the aforementioned opening and closing position, and the gas control device is provided with a compulsory rotation device, and the compulsory rotation device and the foregoing Ignite the fire according to the joint operation from the aforementioned position to the aforementioned closed position, and forcibly turn the aforementioned firepower adjustment dial, so that the firepower of the gas burner becomes-fixed firepower 'and use the forced rotation device to cause the aforementioned fire2 adjustment. The forced rotation of the dial ends before the fire button reaches the valve opening position, and at the valve opening position, the fire button and the Not to mention the fastening relationship between the firepower adjustment dials generated by the aforementioned forced rotation device. According to the present invention, when the operation point is switched off from the valve closing position to the operation point for ignition operation, the gas passage is opened and the gas flows to the gas burner. In this case, you can use the strong weaving device to turn the dial. At the end of the ignition operation, turn off the flame and press the butterfly valve position. At this point, the power adjustment dial has been turned to position and the gas path remains open. If the power adjustment dial is turned at the valve opening position of the ignition button, the gas flow of the fuel gas supplied to the gas burner can be increased or decreased to adjust the power of the gas burner. At this time, because the deduction point can be released and the forced relationship between the forced rotation of the 12218892 adjusting dial is not only detrimental to the operability of the shoulder shoulder dial, but also not to the cooking. The user's sense of rotation operation has an adverse effect. Right: L extinguish the gas burner and move the fire button from the open position to the closed valve position. The gas passage is closed to stop supplying gas to the gas burner. In this car, the compulsory rotating device is placed in a hole located in the semi-control direction of the outer peripheral surface of the button of the aforementioned point and given potential energy to the outside. The cam on the inner peripheral surface of the adjusting dial is adjusted to Ik the moon, and the stop button is moved from the closed position to the open position. The reading tab is stored in the hole and leaves the cam groove. When the valve is opened, the protruding piece and the cam groove are no longer engaged. I: Embodiment; 3 Embodiment of the invention 15 Referring to FIG. 1, the gas control device 1 is incorporated in, for example, a gas furnace 2. At this time, the 'gas furnace 2 has a box-shaped furnace body 2 and two furnaces 23a, 23b are provided in the furnace body 21, and the gas burners 23a, 2 face two openings provided on the panel 22 covering the furnace. .

Further, the gas control device 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 an intermediate casing composed of two portions 11a, lib which are connected to each other in an overlapping manner. The first portion 11a of the housing 8 between the lower sides is provided with a first internal passage 12a 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 12a. 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.忒 The suction piece is connected to the first valve body 32 protruding from the magnet box 31 toward the downstream side of the first internal passage i2a. In the closed state of the solenoid valve 3, the first valve body 32 is contracted and arranged on the first valve body 32 and In the force imparted by the potential energy by the spring 33 between the electromagnetic boxes 31, the valve seat is seated in the valve seat structure 34 provided in the first internal passage 12a through the male and the sealing material 34a. The opening operation of the solenoid valve 3 is performed by a joystick 4 which is inserted in the j-th internal passage 12a via a sealing material 41 and is movable back and forth along the longitudinal direction of the internal passage 12a. Furthermore, a second valve body 42 is provided on the joystick 4, and the second valve body 42 constitutes a main valve together with a valve seat 43 provided in the first internal passage 12a. 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 front-back direction is performed by pressing the push-out button 5 at a point protruding from the front panel 24 (see lg |). The light-off button is cylindrical, and on the end surface of the first internal passage 12a side, as the light-off button 5 is moved, the pusher 5a of the joystick 4 can be connected. Furthermore, the -end knot of the pusher 5a is provided on the heart-shaped cam mechanism 5b on the lower side of the second part. At this time, if the pressing operation point is turned off and the milk is pressed so that the ignition operation is started from the top surface of the thermal adjustment dial described later and the valve closing position of the first internal passage 12a is closed (the state shown in FIG. 1), The lever 5a pushes the joystick 4 to the rear (right side in FIG. 2) to open the main valve, then pushes the valve body 32 to the side of the suction sheet, and the discharge device (not shown) 5 of the ignition device is moved to actuate Ignition position. When the pressing of the flameout button 5 is released from the ignition position, it is guided by the heart-shaped cam mechanism 5b to move in the forward direction (left side of FIG. 2), and then the main valve is kept open to reach the valve opening position where the first internal passage 12a is opened. . When the operation point flameout button 5 is pushed in again from the valve opening position for the flameout operation, the heart cam mechanism 5b is reset to the flameout position. In addition, a gas flow outlet 14 is provided in the first portion 11a on the upstream side of the main valve, and the gas flow outlet 14 is consistent with one end of the substantially l-shaped second internal communication portion 12b provided in the second portion 11b. Each of the first and second internal passages 12a and 12b constitutes a gas passage. 15 On the outer surface of the second portion 11b, four first, second, third, and fourth communication paths 15a, 15b, 15c, and 15d are provided at a predetermined interval from each other. 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. 20 The fuel gas flowing from the gas outflow portion 16 is supplied to the gas burners 23a, 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 cylindrical rotating body 61 which is rotatably provided in the second internal passage i2b 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 dimensions of the respective long grooves 62a, 02b, 62c, and 02d are formed so as to correspond to the pore diameters of the respective communication paths 15a, 15b, 15c, and 15d and deviate from the circumferential direction. In addition, in this embodiment, the four gas flow openings 63a, 63b, 63c having a predetermined amount of the gas flow rate of the fuel gas flowing through the communication paths 15a, 15b, 15c, and 15d toward the gas outflow portion 16 are formed. The orifice members 63 and 63d are installed on the outer peripheral surface of the second part lib in accordance with the communication paths 15a, 15b, 15c, and 15d. 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 rotation angle of the rotating body 61 can be adjusted by using the thermal power adjustment dial 7 provided around the turning-off button 5. 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 first internal passage 丨 la side end portion of the fire-power adjusting dial 7 is engaged with a portion 71 having a predetermined pitch incisive tooth ' and a gear 72 fitted at the end of the rotating body 61 protruding from the second portion 11b. Therefore, the rotating body "synchronizes with the rotation operation of the thermal power adjustment dial 7. Here, when the gas burners 23a and 23b are ignited, in order to ensure the ignition of the fuel gas, for example, the gas burners 23a and 23b If the firepower becomes strong or medium, the fuel gas is supplied to the gas burners 23a and 23b as 1221892. Good 0. Furthermore, "safety considerations" are set up. There are misplaced contacts such as children. Fire button 5 and the discharge device cannot be operated. A so-called safety coffee mechanism is preferred. Referring to Figs. 2 to 6 (e) to 6 (e), in this embodiment, a cam is formed on the inner peripheral surface of the fire adjustment dial 7 protruding from the front panel 24 in the frontward direction. Groove 73, and the first protruding piece 51 opposite to the cam grooved coffee is provided on the peripheral surface of Linhuo in the hollow firepower adjusting dial 7 moving forward and backward to form a forced rotation. At this time, the first protruding The blade 51 is provided in the radial direction hole 52 provided on the outer peripheral surface of the 10-point total fire button under the condition that the potential energy facing the radial direction is provided by the spring S3. In order to ignite the gas burners 23a and 23b, If pressed from the closed position When the flameout button 5 is clicked, the first protruding piece 51 becomes the active section, and the firepower adjustment dial 7 formed by the cam groove 73 of the passive section is rotated to a predetermined position. 15 At this time, since the pressing-in operation of the flameout button 5 is used, The dial 7 is adjusted by turning the firepower. Therefore, for example, it is not necessary to increase the power of the potential energy provided by the spring 17 retracted between the point-extinguishing button 5 and the first portion 11a, and the structure of the gas control device can be simplified. When turning the thermal power adjustment dial 7 at the valve opening position to adjust the thermal power 20 ', since the protruding piece 51 interferes with the cam groove 73, the operability of the thermal power adjustment dial 7 is deteriorated, and the cooking operation feeling of the cook may be bad. In this embodiment, 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, and the pressure of the point-extinguishing button 5 is pressed from the closed 12 12892892 valve position. In the operation, the first protruding piece 51 will be stored in the hole 5 'as the button 5 is moved and reaches the flat portion 74 extending from the cam groove 73 in the longitudinal direction. 5. The i-th protruding piece 51 in the hole percentage moves along the flat portion 74 to reach the ignition position. Moreover, after activating the discharge device to ignite the gas combustion 1123a and 23b, if the point flameout button 解除 is pressed, the heart-shaped cam mechanism is pressed. 5b is guided by the spring ~ the force imparted by the potential energy is slightly returned, and the fire button 5 is clicked to reach the open position. 10 The corresponding guide valve position is on the same level as the thermal adjustment section 74. The rotary guide 75 is on the inner peripheral surface of the dial 7. And formed flat, and along the rotation guide path 75, the thermal power adjustment dial 7 can rotate freely in a clockwise direction or a counterclockwise direction. At this time, the i-th protruding piece 51 accommodated in the hole 52 does not engage the cam groove By this, by forcing the self-closing valve position toward the valve opening position to fire the push-in operation of the push-button W 51 and the cam groove 73 of the cam groove 73, the end is completed before reaching the ignition position 'and In the valve opening position, the protruding piece 51 of the secret fire button 5 and the cam groove of the firepower adjusting dial 7 can be released. Further, if the rotary body 61 is rotated to turn the thermal power adjustment dial 7 in the clockwise direction 20, and the gas flow rate decreases, the gas flow rate increases when the gas flow rate decreases. At this time, the rotating body 61 is arranged so as 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 to engage with a stop (not shown) provided on the furnace body 21. In order to limit the range of rotation of the firepower adjustment dial 7, the second, third and fourth long grooves 62b, 61c, 62d and 13 1221892, the second, third and fourth communication paths 15b, 15c, 15d are respectively -Cause the gas amount in the gas outflow portion 16 to be maximized. On the other hand, at a position where the first long groove 62a coincides only with the first communication path 15a, a rotation stop device 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 to the gas outflow portion 16 and minimize the fire power of 2% and 2 flutter of the gas burner and maximize the gas flow. The gas burners 23a and 23b are made to rotate freely within a range of firepower adjustment 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 clicking sound may occur at a position where the firepower of the gas burners 23a, 23b becomes weak and neutral. 15 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 projecting piece 54 having a smaller diameter than the i-th projecting piece 51 is provided in the radial direction of the outer peripheral surface of the lighted-out, fire-disc 5 under the condition that the potential moon b is provided outward in the radial direction by the spring 56. Hole 5 5 in. Furthermore, at the predetermined positions of the rotation guide path 75, the first and second recesses 77, 88 which are only capable of engaging the second protruding piece 54 in the radial direction are formed. Furthermore, for example, when the thermal power adjustment dial 7 is turned counterclockwise from the minimum flow rate (at this time, the thermal power of the gas burners 23a and 23b is small) and the second protruding piece 54 is engaged with the first concave portion 77, it can be emitted. Click. At this time, not only the long grooves 62a, 14 1221892, but also the second communication path 15b, and the gas flow rate μ toward the gas outflow portion μ is increased, which weakens the firepower of the gas burners 23a, 23b. When the thermal power adjustment dial 7 is rotated counterclockwise, a click sound is generated when the second concave portion 78 is engaged with the second large-out piece 54. At this time, not only the first and second long grooves 5 62a, 62b, but also the third long groove 62c is also connected to the third communication path 15c, so that the gas flow toward the gas outflow portion 16 is increased, so that the firepower of the gas burners 23a, 23b becomes in. Furthermore, a cam groove 73 is formed at the valve closing position of the ignition-off button 5, so that the power adjustment dial 7 can be turned clockwise to exceed the power adjustment range. If 10 exceeds the thermal power adjustment range to turn the thermal power adjustment dial 7 to the cam grooves 73, 4, the first protruding piece 51 is engaged with the right-angled wall portion 73a with respect to the pressing direction of the operation button 5 formed at the end of the cam groove 73. Therefore, it is not necessary to provide an additional operation section for the safety lock mechanism. Even if the point-extinguish button 5 is pressed from the valve closing position to the ignition position, it cannot be moved, which can form a locked position where the ignition device of the gas burner cannot operate. Next, the gas burner 23a of the present invention will be described! Of action. From the valve-closing position shown in Fig. 2, it is assumed that the ignition button 5 is pushed in. The dial 7 can be adjusted by the action of the first protruding piece 51 and the cam groove 73. Here, Fig. 7 shows an example of the operation of the thermal power adjustment dial 7 when the ignition power of the gas burner 23a is extinguished at a weak position and the ignition point is operated by the operation point extinguish button 5. When the operation point extinction button 5 is pushed in, the protruding piece 51 of the operation button 5 abuts against the cam groove 73. If it comes into contact with the cam groove 73, the fire power adjustment dial 7 can be rotated as the 121221892 of the fire button 5 is moved. Accordingly, while the first protruding piece 51 is housed in the hole 52, it reaches the flat portion 74 extending longitudinally from the cam groove 73. At this time, the rotating body 61 rotates through the gear 72, and at this position, the i, 5th The second and third long grooves 62b, 62c, and 62d are respectively connected to the first, second, and third communication paths 15b, 15c, and 15d, respectively, and the firepower that can flow into the gas burner 23a toward the gas outflow portion 16 is medium. Fuel gas (see Figure 6 (d) and Figures 11 (a) and 11 (b)). Continue to press the fire button on the right, as shown in Figure 8. You can press the operation lever 4 backward through the push rod 5a to open the main valve, and reach the ignition that pushes the valve body 32 to the side of the adsorption sheet. position. Once the ignition position is reached, the ignition operation of the gas burner 23a is performed by the discharge setting. In addition, once the flame detection device 26 (see Fig. 1) installed near the gas burner 23a detects the flame of the gas burner 23a, the signal from the self-controlling 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 click-off button 5 is released, the click-off button 5 is guided to the valve opening position shown in Fig. 9 by the heart cam mechanism 5b. 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. 20 Furthermore, 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 , 3rd and 4th long grooves 621), 620, 6201 will be connected to the 2nd, 3rd and 4th communication roads 15 and 15 respectively. 15d is the same, and the fuel of the gas burner 23a is a strong gas flow fuel 16 gas flows toward the gas outflow portion b (see Figure 6 (e) and Figure 10). On the other hand, it is to reduce the firepower of the gas burner 23a from medium fire. If the second protruding piece 54 engages the i-th concave portion 77 and then rotates the firepower adjustment dial 7 clockwise until the sound of the tower, the i-th and the second F62a, 62b correspond to the first and second communication paths 15a, 15b, respectively, and the fire power of the tile burner ^ is a weak gas flow of fuel gas flowing toward the gas (see Figure S. 3 (a) and 3 (b)). Next, if the firepower adjusting dial 7 is turned clockwise until the first protruding piece 51 contacts the anti-rotation device 76, the first long groove 62a is only consistent with the first communicating path 15a 'and the firepower of the gas combustion H23a is small and minimum. Fuel gas with gas flow flows toward the gas outflow portion 16 (see FIG. 6 and FIG. 6 (b)). When the gas burner 23a is extinguished, if the operating point extinguishing button 5 is pressed backward from the valve opening position, the heart-shaped cam mechanism 5b is reset, and the extinguishing button 5 15 is subjected to the amount of potential power given by the spring. The fire adjustment dial 7 shown is retracted to the protruding closed valve position. At this time, the control lever 4 whose pressing force has been released by the push rod 5a is moved in the backward direction by the amount of potential force imparted by the spring 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 turned off. If the control device 20 recognizes 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, making the flameout button 5 impossible. Pressed and securely locked. 17 In addition, in the present embodiment, when the operation point flameout button 5 is pressed in for ignition operation, although the firepower adjustment dial 7 can be rotated to a position where the firepower of the gas burners 23a and 23b is neutral by a forced rotation device, But it is not limited to this. For example, as shown in Fig. 13 (a), the cam groove 73 may be configured so that the fire power adjusting dial 7 can be rotated to a position where the fire power of the gas burners 23a and 23b is strong. Moreover, as shown in FIG. 13 (b), when the gas burner 23a, 23b is about to be extinguished, and when the thermal adjustment dial 7 is located at a position where the thermal power is strong, the next ignition operation may be performed. In the meantime, the ignition operation is performed in the original state, and only at the side where the firepower is smaller than the middle firepower position, when the gas burners 23a and 23b are about to ignite, the firepower adjustment dial 7 can be rotated to the gas burner 23a. , 23b's firepower becomes the middle position. Advantageous Effects of Invention As described above, a gas control device of the present invention has the effect of not only not affecting the operability of the thermal power adjustment dial, but also preventing the cooker from adversely affecting the rotary operation feeling.
