本発明は種火をオーブン庫外へ設けたオーブンに関して
、主バーナへの点火の確実性1、安全性を向上させよう
とするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention aims to improve the reliability and safety of igniting the main burner in an oven in which a pilot flame is provided outside the oven chamber.
近年、ホームメイドクツキングとして、手づくりの味を
要求される指向であり、家庭でパンやヨーグルト等を作
る傾向が顕著である。In recent years, there has been a growing trend toward home-made shoes, which requires the taste of homemade products, and there is a noticeable trend toward making bread, yogurt, etc. at home.
このような背景にあって30〜300°Cまで温度コン
トロールができるオーブンが開発されている。Against this background, ovens whose temperature can be controlled from 30 to 300°C have been developed.
一般に、パン作りのだめのイースト菌発酵等の低温調理
を意図したオーブンはバーナを点滅して温度をコントロ
ールして低温度加熱を得ている。Generally, ovens intended for low-temperature cooking such as yeast fermentation for bread making use flashing burners to control the temperature and obtain low-temperature heating.
一方、点火方式は一般にダイレクト点火や、種火点火方
式があるが、前者は点火ミスが起きたり、くり返し点火
操作を行なう等複雑でかつ不確実な面があった。On the other hand, ignition methods generally include direct ignition and pilot ignition methods, but the former is complicated and uncertain, such as ignition errors and repeated ignition operations.
また後者は点火の確実性維持より、主バーナに近接して
設けられ主バーナと同様にオーブン庫内の昇温に影響を
与えていたので、低温時においては、低い温度30〜4
5℃がだせなかった。In addition, in order to maintain the reliability of ignition, the latter was installed close to the main burner, and like the main burner, it affected the temperature rise inside the oven.
I couldn't reach 5℃.
そこで燃焼室の熱気を主バーナのものに限定し、常時加
熱している種火からの影響を少くするために、種火をオ
ーブン庫外に設け、主バーナの燃焼停止時にはオーブン
温度上昇も少くシ、低温度制御を可能にしている。Therefore, in order to limit the hot air in the combustion chamber to that of the main burner and to reduce the influence of the constantly heating pilot flame, the pilot flame is placed outside the oven chamber, and when the main burner stops burning, the oven temperature will rise less. This enables low temperature control.
この結果、オーブン庫内にある主バーナへの点火のため
に種火と主バーナを結ぶ点火装置が要求されていた。As a result, there has been a need for an ignition device that connects the pilot flame to the main burner in order to ignite the main burner inside the oven.
そこで一般的には種火と主バーナの間に火移り用パイプ
バーナを設け、その上方に平板のカバーをかぶせ、種火
付近からガスを出し走行しながら火移りして主バーナへ
点火する方法がとられている。Generally speaking, a pipe burner for flame transfer is installed between the pilot flame and the main burner, a flat plate cover is placed over the pipe burner, and gas is emitted from the vicinity of the pilot flame and the flame transfers while the vehicle is running to ignite the main burner. is taken.
また、両端開口のパイプを設け、主バーナから出てきた
生ガスを、種火へ導いて、フラッシュバック点火する方
法が考えられている。Another method has been considered in which a pipe with openings at both ends is provided to guide the raw gas coming out of the main burner to a pilot flame for flashback ignition.
しかし、このような従来の点火装置であれば、前者にお
いては煮こぼれ等による炎口の目づまり、小さい径のノ
ズルへゴミ、虫等の付着による目づまりがあり、危険な
状態となることがあった。However, with such conventional igniters, the flame opening may become clogged due to boiling over, or the small diameter nozzle may become clogged due to adhesion of dirt, insects, etc., resulting in a dangerous situation. Ta.
またフラッシュバック点火方式においては点火音、パイ
プの内へ虫等の巣作りなどでパイプづまりが起きたり、
点火時間が前者にくらべて長いという欠点があった。In addition, with the flashback ignition method, pipe clogging may occur due to ignition noise, insects, etc. nesting inside the pipe,
The disadvantage was that the ignition time was longer than the former.
そこで点着火を確実にするために火移りバーナを二つ以
上組み合せることも考えられるが、故障原因が同じであ
れば、火移らバーナはどれも同じように故障する可能性
が高くなるため、点火の確実性、安全性の確保は困難で
あった。Therefore, it is possible to combine two or more flame shifting burners to ensure ignition, but if the cause of failure is the same, all flame shifting burners are likely to fail in the same way. It was difficult to ensure ignition reliability and safety.
本発明は上記の欠点を解消するもので、以下その実施例
を図面とともに説明する。The present invention solves the above-mentioned drawbacks, and embodiments thereof will be described below with reference to the drawings.
1はオーブン庫であり、底部にバーナ2が設けられる。1 is an oven chamber, and a burner 2 is provided at the bottom.
3は種火であり、オーブン庫1の外に設け、低温調理時
にオーブン庫1内に熱影響を与えないように配慮してい
る。Reference numeral 3 denotes a pilot flame, which is provided outside the oven chamber 1 so as not to have a thermal effect on the inside of the oven chamber 1 during low-temperature cooking.
4はガス通路を開閉し、オーブン庫1内の温度を0N−
OFF 制御する電磁弁、5ばこの電磁弁4からバー
ナ2ヘガスを導く導管、6はこの導管5から分岐し種火
3ヘガスを導く導管、7はこの導管6に連続して設けら
れ種火3からバーナ2の近傍まで延出した火移りバーナ
、8はこの火移りバーナ7の上方にわずかな間隙tを確
保して装置したフラッシュバック管である。4 opens and closes the gas passage to bring the temperature inside the oven chamber 1 to 0N-
OFF A solenoid valve to be controlled, 5 a conduit that leads gas from the solenoid valve 4 of the cigarette to the burner 2, a conduit 6 branching from this conduit 5 and leading gas to the pilot flame 3, and a conduit 7 provided continuously with this conduit 6 and a pilot flame 3. A flashback pipe 8 is a flashback pipe installed above the flash burner 7 with a slight gap t.
前記火移りバーナ7はパイプ状をなし、種火3附近から
バーナ2に接近した位置まで適当な間隔をおいて多数の
炎口9が設けられ、種火3近くの炎口9に点火された火
は順次相隣接した炎口9に火移りし、バーナ2に点火す
るように配慮されている。The shifting burner 7 has a pipe shape, and is provided with a large number of flame ports 9 at appropriate intervals from the vicinity of the pilot flame 3 to a position close to the burner 2, and the flame ports 9 near the pilot flame 3 are ignited. The fire is designed to spread to adjacent flame ports 9 one after another and ignite the burner 2.
フラッシュバック管8は火移りバーナ7の上面を覆うよ
うに設けられ、また全長に亘ってひさし部10を設けて
いる。The flashback tube 8 is provided so as to cover the upper surface of the transfer burner 7, and is provided with an eaves portion 10 over its entire length.
これは調理中の煮汁や油が直接大杉りバーナ7に付着し
て炎口9の目づまりを防止する配慮による。This is to prevent the boiling liquid and oil during cooking from directly adhering to the Osugi burner 7 and clogging the flame opening 9.
そしてこの大杉9バーナ1およびフラッシュバック管8
はともに種火3側へ高くなるように傾斜して設けられて
いる。And this Osugi 9 burner 1 and flashback tube 8
Both are provided so as to be higher toward the pilot flame 3 side.
このフラッシュバック管8は天啓すバーナ7の炎口9が
目づまりを起した際に、バーナ2から出たガスの一部を
種火3側へ誘導し、バックフラッシュによってバーナ2
に点火し、オーブン庫1内にガスが充満して爆発する等
の危険を未然に防止するために設けたものであり、傾斜
させているのはバックフラッシュ点火のためのガス誘導
の確実を期すためである。This flashback tube 8 guides a part of the gas emitted from the burner 2 to the pilot flame 3 side when the flame port 9 of the heavenly burner 7 becomes clogged, and by backflushing the burner 2
This is to prevent the risk of explosion due to gas filling inside the oven chamber 1, and the reason why it is slanted is to ensure gas guidance for backflash ignition. It's for a reason.
フラッシュバック管8によって点火しなければならない
ような事態は避けなければならないものであり、このよ
うな配慮から前述のように火移りバーナγの炎口9の目
づまりによる事故を防止するために火移りバーナ7の上
方をフラッシュバック管8で覆うようにしている。It is necessary to avoid a situation where the flashback tube 8 has to be used to ignite the ignition, and from this consideration, as mentioned above, in order to prevent accidents due to clogging of the flame port 9 of the transfer burner γ, it is necessary to The upper part of the transfer burner 7 is covered with a flashback tube 8.
しかしながら、万一の際にも安全は確保される必要があ
り、フラッシュバック管8はそのための対策である。However, it is necessary to ensure safety even in the event of an emergency, and the flashback tube 8 is a measure for this purpose.
とくに低温調理に際しては、バーナ2を点滅させるので
あるが、電磁弁4の開閉によってこれを行い、しだがっ
て電磁弁4の閉塞時には導管5゜6にガスは供給されず
、したがって大杉シバーナ7がオーブン庫1内に位置す
ることによる熱分布影響はない。Especially when cooking at a low temperature, the burner 2 is blinked, but this is done by opening and closing the solenoid valve 4. Therefore, when the solenoid valve 4 is closed, gas is not supplied to the conduit 5.6, and therefore the Osugi Shibana 7 There is no effect on the heat distribution due to the fact that the oven is located inside the oven chamber 1.
以上のように本発明によれば、低温調理時に種火の熱が
悪影響を与えることがなり、シかも点火は確実で、万−
火移りバーナが目づまりを起しても、バーナへの安全な
点火はフラッシュバック管によって保証されるものであ
り、ガス調理器の性能向上ど安全対策に果たす役割は大
きい。As described above, according to the present invention, the heat of the pilot flame does not have an adverse effect during low-temperature cooking, and the ignition is reliable and safe.
Even if the transfer burner becomes clogged, the flashback tube ensures safe ignition of the burner, and it plays a major role in improving the performance of gas cookers and as a safety measure.
