Description

本発明は、鍋内を大気圧以上に昇圧して炊飯する圧力式炊飯器に係り、さらに詳しくは、沸騰維持工程中に圧力弁を強制的に開放したときに、圧力弁からおねばを含む大量の蒸気が噴出されても外部へおねばが吹きこぼれないようにした圧力式炊飯器に関するものである。   The present invention relates to a pressure-type rice cooker that cooks rice by raising the pressure in the pan to more than atmospheric pressure, and more specifically, includes a rice pad from the pressure valve when the pressure valve is forcibly opened during the boiling maintenance step. The present invention relates to a pressure-type rice cooker that prevents the spilling of the rice cake outside even if a large amount of steam is ejected.

電気炊飯器は、今や一般家庭において既に必需品となっており、これまで様々なタイプの炊飯器が開発され使用されている。これらの炊飯器は、炊飯中に大量の蒸気及びおねばが発生し、これらが炊飯器から外へ飛び出して、周辺のテーブルや床などを汚染することがある。特に、おねばには粘性があることから、おねばが泡となって蓋体から外へ飛び出して、蓋体の表面に付着してこびりつき、また、蓋体などの隙間などに入り込んで頑固な付着物となってしまって洗浄などでは除去できず、剥離しようとすると鋭利な刃物などで削らなければならず、このとき蓋体などを傷つけてしまうことがある。また、このような頑固な付着物は、ときに細菌の巣窟となり衛生上の問題が発生することがある。   Electric rice cookers are now a necessity in ordinary households, and various types of rice cookers have been developed and used so far. In these rice cookers, a large amount of steam and rice balls are generated during rice cooking, which may jump out of the rice cooker and contaminate surrounding tables and floors. In particular, since the rice ball is viscous, the rice ball becomes a bubble and jumps out of the lid, sticks to the surface of the lid, and sticks into the gap of the lid. It becomes an adhering matter and cannot be removed by washing or the like, and if it is to be peeled off, it must be shaved with a sharp blade or the like, which may damage the lid. Also, such stubborn deposits sometimes become a burial site for bacteria and may cause sanitary problems.

このような課題を解決するために、鍋内で発生した蒸気及びおねばが蓋内を通過して大気中に放出されるまでの過程でこれらを分離して、重いおねばを受容器などに溜め、蒸気を大気中へ放出するようにした炊飯器が提案されている。   In order to solve such problems, steam and rice balls generated in the pan are separated in the process until they pass through the lid and are released into the atmosphere, and the heavy rice balls are used as a receiver. A rice cooker has been proposed that stores and discharges steam into the atmosphere.

例えば、炊飯器本体の開口部を覆う蓋体におねば容器を取付けて、このおねば容器に、炊飯中に発生するおねばを含んだ蒸気を容器に取り入れる蒸気案内筒と、蒸気を排出する蒸気口と、蒸気案内筒の出口側を囲むガイド壁を設けた炊飯器が提案されている(下記特許文献1参照)。この炊飯器によれば、蒸気案内筒から蒸気口に至る蒸気の通路を長くとれるために、おねばを含んだ蒸気がおねばと蒸気とに分離されて、おねばの吹きこぼれを防止できる。また、おねば容器にさらに溜まり凹み部、この溜まり凹み部と内鍋を連通する連通口と、内鍋の内圧によって連通口を開閉する開閉弁とを設けた炊飯器が提案されている(下記特許文献2参照)。この炊飯器によれば、おねばの吹きこぼれを確実に防止できる。   For example, a container is attached to the lid that covers the opening of the rice cooker body, and a steam guide tube that takes in steam containing rice crackers generated during rice cooking into this container and discharges steam. There has been proposed a rice cooker provided with a steam port and a guide wall surrounding the outlet side of the steam guide tube (see Patent Document 1 below). According to this rice cooker, since the steam passage extending from the steam guide tube to the steam port can be taken long, the steam containing the rice cracker is separated into the rice cake and the steam, and the spilling of the rice cake can be prevented. In addition, rice cookers have been proposed in which a rice bowl is further provided with a pool recess, a communication port that communicates the pool recess with the inner pan, and an open / close valve that opens and closes the communication port by the internal pressure of the inner pan (see below). Patent Document 2). According to this rice cooker, it is possible to reliably prevent the spilling of the rice balls.

上記特許文献1、2の炊飯器によれば、おねばと蒸気とがおねば容器内で分離されて、蒸気のみが大気中へ放出されるので上記課題を解決できる。しかしながら、これらの炊飯器は、いずれも鍋内を略大気圧状態で炊飯するものであることから、炊飯中に吹き出すおねばを含んだ蒸気の量が然程多くならず、また、その勢いも強くならないので、提案されたおねば容器などでの対応が可能である。   According to the rice cookers of Patent Documents 1 and 2, the rice cracker and the steam are separated in the container, and only the steam is released into the atmosphere, so that the above problem can be solved. However, since all of these rice cookers cook rice in the pan at a substantially atmospheric pressure, the amount of steam containing rice balls that blow out during cooking is not so large, and the momentum is also high. Since it does not become strong, it can be handled with the proposed container.

近年、鍋内を大気圧以上に昇圧して炊飯する圧力式炊飯器が開発されている。本願の出願人は、鍋内を大気圧以上に昇圧し、しかも、沸騰維持工程中に圧力弁を強制的に所定回数間歇的に開放して炊飯する圧力式炊飯器を開発して既に特許を取得している(例えば、特許第3851293号、特許4094022号、特許4094023号参照)。   In recent years, pressure rice cookers have been developed that cook rice by raising the pressure in the pan above atmospheric pressure. The applicant of the present application has developed a pressure-type rice cooker that boosts the inside of the pan to atmospheric pressure or more and forcibly opens the pressure valve for a predetermined number of times during the boiling maintenance process and has already patented it. (See, for example, Japanese Patent No. 3851293, Japanese Patent No. 4094022, Japanese Patent No. 4094023).

例えば、特許第3851293号の圧力式炊飯器は、水と米とを含む被炊飯物を収容する鍋と、前記鍋を収容する開口部及び該鍋内の被炊飯物を加熱する加熱手段を有する炊飯器本体と、前記鍋及び前記炊飯器本体の開口部を塞ぐ蓋体と、前記鍋内の圧力を略一定とするように鍋内と外気とを連通或は遮断する開閉機構を有する圧力弁と、前記圧力弁に付設され該圧力弁を強制的に開状態にするための圧力弁開放機構と、前記加熱手段の加熱量を制御するとともに前記圧力弁開放機構による前記圧力弁の開作動の制御を行う制御手段とを備え、一連の炊飯工程のうち沸騰維持工程中を加圧状態にして炊飯を行う圧力式炊飯器において、前記圧力弁は、前記沸騰維持工程中で前記圧力弁が前記圧力弁開放機構により強制的に開作動されていない状態のときに前記鍋内の圧力が1.10〜2.20気圧に維持されるように形成されており、前記制御手段は、前記鍋内の被炊飯物が沸騰温度であり、且つ前記沸騰維持工程の初期段階の水分が十分にある間に前記圧力弁開放機構により前記圧力弁を少なくとも1回強制的に開作動させて沸騰中の鍋内の圧力を大気圧近傍となるように一気に低下させることにより突沸現象を発生させて米粒を撹拌するように制御するようにしたものである。   For example, the pressure-type rice cooker of Japanese Patent No. 3852293 has a pan that houses a cooked rice containing water and rice, an opening that houses the pan, and a heating means that heats the cooked rice in the pan. A pressure valve having a rice cooker body, a lid for closing the pan and the opening of the rice cooker body, and an open / close mechanism for communicating or blocking the inside of the pan and the outside air so that the pressure in the pan is substantially constant A pressure valve opening mechanism that is attached to the pressure valve and forcibly opens the pressure valve; and controls a heating amount of the heating means and opens the pressure valve by the pressure valve opening mechanism. A pressure-type rice cooker that cooks rice in a pressurized state in a boiling maintenance process in a series of rice cooking processes, wherein the pressure valve is the pressure valve in the boiling maintenance process. It is not forcibly opened by the pressure valve opening mechanism. The pressure in the pan is maintained at 1.10 to 2.20 atm, and the control means is configured such that the cooked rice in the pan has a boiling temperature and the boiling While the moisture in the initial stage of the maintenance process is sufficient, the pressure valve is forcibly opened at least once by the pressure valve opening mechanism, so that the pressure in the boiling pan is reduced to near atmospheric pressure at once. This causes the bumping phenomenon to occur and controls the rice grains to be stirred.

この圧力式炊飯器によれば、鍋内を大気圧以上、すなわち、1.10〜2.20気圧に昇圧して、沸騰維持工程中に圧力弁が強制的に開成されるので、開成時に鍋内が高圧状態から大気圧近傍まで一気に低下し、鍋内で激しい沸騰現象、いわゆる突沸現象が発生して、この突沸現象により被炊飯物が攪拌されるので、炊飯ムラの無い美味しい炊き上がりとなる。しかしながら、圧力弁の開動作のときに、圧力弁からはおねばを含んだ蒸気が一度に大量に且つ勢いよく噴出する。このおねばを含んだ蒸気の量及び勢いは、これまでの常圧式炊飯器と比べて、数倍の量及び勢いとなるので、常圧式炊飯器のおねば容器などの技術をそのまま採用できず改良を加えたものとなっている。   According to this pressure-type rice cooker, the pressure inside the pan is increased to atmospheric pressure or higher, that is, 1.10 to 2.20 atm, and the pressure valve is forcibly opened during the boiling maintenance process. The inside drops rapidly from the high pressure state to near atmospheric pressure, and a violent boiling phenomenon, so-called bumping phenomenon occurs in the pan, and the cooked rice is agitated by this bumping phenomenon, so it becomes a delicious cook without uneven rice cooking. . However, during the opening operation of the pressure valve, a large amount of steam including a tortoise is ejected from the pressure valve at once and vigorously. The amount and momentum of the steam containing this rice ball is several times the amount and momentum compared to conventional atmospheric rice cookers, so the technology such as the rice vessel of the atmospheric rice cooker cannot be adopted as it is. It has been improved.

また、同出願人は、上記特許のものも含めこれまで開発した圧力式炊飯器は、圧力弁の数を1個にしていたが、その数を増やして複数にした炊飯器も提案している(上記特許文献3参照)。   In addition, the applicant has also proposed a rice cooker that has been developed so far, including those of the above-mentioned patents, in which the number of pressure valves is one, but the number is increased to a plurality. (See Patent Document 3 above).

この圧力式炊飯器のように、圧力弁を複数にすると、その数が増えた分、さらにおねばを含んだ蒸気の量が多くなり且つ勢いも強くなる。例えば、複数の圧力弁を同時に開放させると、一度に大量のおねばを含んだ蒸気が大量に且つ勢いよく圧力弁から噴出する。そのために、蒸気口から一度に大量の蒸気が放出されると火傷などの危険性が増し、また、おねばが外部へ放出されて周辺を汚すとともに、このおねばには、旨み成分が含まれているので、この旨み成分が外へ排出されてしまい、その結果、旨みが欠けた炊き上がりとなる。さらに、おねばも大量に噴出されるので、貯留した大量のおねばを鍋内に戻すときに、一箇所に戻すと、その箇所が水っぽくなるなどの課題がある。   If there are a plurality of pressure valves like this pressure-type rice cooker, the amount of steam including rice balls will increase and the momentum will increase. For example, when a plurality of pressure valves are opened at the same time, a large amount of steam containing a large amount of steam is ejected from the pressure valves with great force. For this reason, if a large amount of steam is released from the steam outlet at once, the risk of burns and the like increases, and the tobacco is released to the outside and contaminates the surroundings. Therefore, this umami component is discharged to the outside, and as a result, the cooked food lacks umami. Furthermore, since a large amount of rice balls are ejected, when returning a large amount of stored rice balls to the inside of the pan, there is a problem that if the water is returned to one place, the place becomes watery.

そこで、本発明は、このような従来技術の課題を解決するためになされたもので、本発明の目的は、沸騰維持工程において、複数の圧力弁を同時に開放しても、蒸気とおねばとが確実に分離されて、蒸気噴出の勢いが抑制され且つおねばの吹きこぼれがなく、しかも炊きムラのない美味しい炊き上げができる圧力式炊飯器を提供することにある。   Therefore, the present invention has been made to solve such a problem of the prior art, and the object of the present invention is to provide steam and wastewater even if a plurality of pressure valves are opened simultaneously in the boiling maintaining step. An object of the present invention is to provide a pressure-type rice cooker that is surely separated, can suppress the momentum of steam eruption, does not spill over, and can cook deliciously without uneven cooking.

また、本発明の他の目的は、一時貯留された旨み成分のおねばを鍋内のご飯に万遍なく分散させて旨みのある美味しい炊き上げができる圧力式炊飯器を提供することにある。   Moreover, the other object of this invention is to provide the pressure type rice cooker which can disperse | distribute temporarily the taste component of the umami component to the rice in a pan uniformly, and can cook deliciously with a taste.

The lid body 9 is pivotally supported on the rice cooker body 2 by using the frame body 11 using the hinge member 28 and the pivot pin 29, and the lid body 9 can be opened and closed to the rice cooker body 2. A lid heater 35c is disposed between the frame 11 and the inner lid 12 so as to be covered with the lid cover 31, and a lid temperature sensor (not shown) is provided. Near the center of the inner lid 12 is a pressure valve 38 that controls the steam pressure in the rice cooker body 2 to adjust the pressure, and is opened when the pan is abnormally pressurized due to a failure of the pressure valve, etc. A safety valve (not shown) for releasing pressure is mounted.

外蓋10には、おねばを一時貯留するおねば貯留タンク13が着脱自在に装着されている。おねばは、立上加熱工程、沸騰維持工程でおねば貯留タンク13に溜まり、蒸らし工程で、鍋6内の圧力が低下すると、負圧弁30より、鍋6内に還元されるようになっている。   The outer lid 10 is detachably mounted with a tow storage tank 13 for temporarily storing a tow. The rice balls are collected in the storage tank 13 in the start-up heating process and the boiling maintenance process, and when the pressure in the pan 6 is reduced in the steaming step, the negative pressure valve 30 returns to the pan 6. Yes.

内蓋12の外周囲には、鍋6のフランジ部7と内蓋12とをシールする鍋パッキン32が外枠34に支持されて装着されている。炊飯器本体2内に鍋6を収容して蓋体9で覆うと、鍋パッキン32が鍋6の開口縁部に圧接して鍋6が閉鎖される。   Around the outer periphery of the inner lid 12, a pot packing 32 that seals the flange portion 7 of the pot 6 and the inner lid 12 is supported and attached to the outer frame 34. When the pan 6 is accommodated in the rice cooker body 2 and covered with the lid 9, the pan packing 32 is pressed against the opening edge of the pan 6 and the pan 6 is closed.

また、内蓋12の鍋6側には、貯留タンクに溜められたおねばを、鍋6内に拡散して供給するための、おねばシャワー板27が取り付けられている。   Further, on the pot 6 side of the inner lid 12, there is attached a toy shower plate 27 for diffusing and supplying the toy collected in the storage tank into the pot 6.

蓋体9は、その内蓋12がステンレス鋼材やアルミニウム材あるいは両者からなるクラッド材で形成されたものである。内蓋12は金属板を周縁部と内部との間に段差が形成されるように円盤状にプレス成型して形成され、周縁部にはゴム製の鍋パッキン32を介して硬質のプラスチック製の外枠34を取り付けている。外枠34には内蓋を装着するための係止部が設けてある。鍋パッキン32は、鍋6のフランジ部7と密着し、鍋6をシールすることにより圧力を保持する。鍋パッキン32は、耐久性、耐熱性に優れているシリコンゴムから形成するのが好ましい。   The lid 9 has an inner lid 12 formed of a stainless steel material, an aluminum material, or a clad material made of both. The inner lid 12 is formed by press-molding a metal plate into a disk shape so that a step is formed between the peripheral portion and the inside, and the peripheral portion is made of a hard plastic through a rubber pot packing 32. An outer frame 34 is attached. The outer frame 34 is provided with a locking portion for mounting the inner lid. The pot packing 32 is in close contact with the flange portion 7 of the pot 6 and maintains pressure by sealing the pot 6. The pot packing 32 is preferably formed from silicon rubber having excellent durability and heat resistance.

蓋体の内側の内ケース3に形成された切り欠き部と対向する部分には、この切り欠き部を塞ぐことができる突起が形成されている。   A protrusion that can close the notch is formed in a portion facing the notch formed in the inner case 3 inside the lid.

また、内蓋12には、選択的に動作可能にした2つの圧力弁が設けられている。それぞれの圧力弁は、同じ口径の弁孔を有している。なお、図3は蓋体9から内蓋12を外して外蓋10の方を見た平面図である。外蓋10のほぼ中央付近に二つ並べて圧力弁38(図4参照)及び弁開放機構が設けられており、これらの弁開放機構の一部である作動棹45が蓋カバー31の中央付近の孔から外蓋10内に突出している。これらの圧力弁は、外蓋10の内部に取り付けられたソレノイド(不図示)によって作動棹45が駆動されるが、本実施例では、それぞれの圧力弁とソレノイドの間にはリンク機構が設けられ、このリンク機構を介してソレノイドの動きが圧力弁に伝えられる。   The inner lid 12 is provided with two pressure valves that can be selectively operated. Each pressure valve has a valve hole with the same diameter. FIG. 3 is a plan view of the outer lid 10 with the inner lid 12 removed from the lid body 9. Two pressure valves 38 (see FIG. 4) and a valve opening mechanism are provided side by side in the vicinity of the center of the outer lid 10, and an operating rod 45, which is a part of these valve opening mechanisms, is provided near the center of the lid cover 31. It protrudes into the outer lid 10 from the hole. In these pressure valves, the operating rod 45 is driven by a solenoid (not shown) attached to the inside of the outer lid 10, but in this embodiment, a link mechanism is provided between each pressure valve and the solenoid. The movement of the solenoid is transmitted to the pressure valve through this link mechanism.

圧力弁38は、図4に示すように、弁孔39を有する弁座40と、この弁座40の上に自重により弁孔39を塞ぐ金属性のボール41と、このボール41を覆うカバー42とからなる。これらの圧力弁38は、鍋6内の圧力とボール41の自重とのバランスによって、ボール41が弁孔39上に移動されたり離れたりすることにより、さらには弁開放機構43の制御によって強制的にボール41を移動させることにより、弁孔39の開閉が行われる。   As shown in FIG. 4, the pressure valve 38 includes a valve seat 40 having a valve hole 39, a metal ball 41 that closes the valve hole 39 by its own weight on the valve seat 40, and a cover 42 that covers the ball 41. It consists of. These pressure valves 38 are forcibly controlled by the valve opening mechanism 43 when the ball 41 is moved or separated from the valve hole 39 according to the balance between the pressure in the pan 6 and the weight of the ball 41. The valve hole 39 is opened and closed by moving the ball 41 to the right.

この実施形態では、圧力弁を2個にし、それらの弁の口径を同じにしたが、個数は2個以上であってもよく、また、それらの弁口径を異ならせてもよい。これにより、炊飯量に対応したきめ細かい炊飯制御が可能になる。   In this embodiment, two pressure valves are used and the diameters of the valves are the same. However, the number may be two or more, and the diameters of the valves may be different. Thereby, fine rice cooking control corresponding to the amount of rice cooking becomes possible.

次に、図5〜図9を参照しておねば貯留タンクを説明する。なお、図5は図4の蓋部分の拡大断面図、図6は図4のおねば貯留タンクの下ケース上面斜視図、図7は図4のおねば貯留タンクの下ケース上面図、図8は図4おねば貯留タンクの上ケース上面斜視図、図9は図4のおねば貯留タンクの上ケース底面斜視図である。   Next, the storage tank will be described with reference to FIGS. 5 is an enlarged cross-sectional view of the lid portion of FIG. 4, FIG. 6 is a perspective view of the upper case of the lower storage tank of FIG. 4, FIG. 7 is a lower case top view of the lower storage tank of FIG. 4 is a top perspective view of the upper case of the storage tank of FIG. 4, and FIG. 9 is a bottom perspective view of the upper case of the storage tank of FIG.

おねば貯留タンク(以下、貯留タンクという)13は、2個の圧力弁に共通したタンク、すなわち両圧力弁から噴出されるおねばを含む蒸気を受容するタンクとなっている。タンクを共通にすると、設計及び管理が容易になるが、沸騰維持工程中に2個の圧力弁が同時に開放されると、おねばを含んだ蒸気量が多くなり且つその勢いが1個の圧力弁のときよりも倍乃至それ以上になるので、タンクの容積が小さいとおねばが外へ放出されてしまうことがある。この対策として、貯留タンクの容積を大きくすることが考えられるが、単に大型にしただけでは、おねばと蒸気とを効率よく分離させて、おねばを残し、蒸気のみを蒸気口から放出させることができない。また、熱い蒸気が蒸気口から大量に噴出されると、火傷をさせるなどの危険性があるので、この危険を回避するために、勢いを弱め、多少冷して放出する必要がある。   The rice storage tank (hereinafter referred to as a storage tank) 13 is a tank that is common to the two pressure valves, that is, a tank that receives the steam containing the rice cake ejected from both pressure valves. A common tank facilitates design and management, but if the two pressure valves are opened simultaneously during the boiling maintenance process, the amount of steam containing the tomb increases and the momentum is one pressure. Since it is twice or more than that of the valve, if the volume of the tank is small, the rice cake may be discharged to the outside. As a countermeasure, it is conceivable to increase the volume of the storage tank. However, simply increasing the size of the storage tank efficiently separates the stomach and steam, leaving the mouth, and releasing only steam from the steam outlet. I can't. In addition, if a large amount of hot steam is ejected from the steam port, there is a risk of burns and the like. Therefore, in order to avoid this danger, it is necessary to reduce the momentum and release it with some cooling.

そこで、本発明の実施形態に係る貯留タンクは、圧力弁の個数に対応して、内部容積を大きく、例えば、圧力弁が2個の場合は、圧力弁1個の場合の1.2倍〜2倍程度の容積にして、且つ、上記の課題を解決したものである。   Therefore, the storage tank according to the embodiment of the present invention has a large internal volume corresponding to the number of pressure valves. For example, when there are two pressure valves, the storage tank is 1.2 times as large as when one pressure valve is used. The volume is approximately doubled and the above-mentioned problems are solved.

この貯留タンク13は、内部に水平方向に広く広がった偏平状の空室を形成し、この空室がおねばを分離するおねば分離室と、蒸気を一時溜め待機させる蒸気溜め室と、蒸気を外部へ排出する蒸気排出路とに区画して、圧力弁から噴射されたおねばを含む蒸気がおねば分離室で広い偏平状の空間で拡散されておねばと蒸気とが分離されて、分離された蒸気が蒸気溜め室で一時待機して溜められた後に蒸気排出路に入り込み、蒸気口から排出される。   The storage tank 13 forms a flat vacant space that spreads widely in the horizontal direction inside, a vacant separation chamber that separates the gusset, a vapor reservoir chamber that temporarily accumulates and waits for vapor, and a vapor Is divided into a steam discharge passage that discharges to the outside, and the steam including the powder injected from the pressure valve is dispersed in a large flat space in the separation chamber, and the steam is separated from the steam, The separated steam is temporarily stored in the steam storage chamber, and then enters the steam discharge path and is discharged from the steam port.

この構成によれば、貯留タンクの容積は大きくされ、且つ偏平状の空室内には障害となる隔壁などがないので、おねばを含む蒸気が貯留タンク内で一気に拡大分散され、おねばと蒸気とが効率よく分離される。また、おねば分離室で分離された蒸気が蒸気溜め室で一時待機して溜められ、冷却された後に蒸気排出路に入り込み、蒸気口から排出されるので、おねばが蒸気口から出てくることがなく、また、排出される蒸気も冷却されているため、炊飯時の安全性が確保される。   According to this configuration, since the volume of the storage tank is increased and there is no partition wall or the like that becomes a hindrance in the flat vacant chamber, the steam including the rice cake is expanded and dispersed all at once in the storage tank. And are separated efficiently. In addition, the steam separated in the separation chamber is temporarily stored in the steam storage chamber, and after being cooled, enters the steam discharge path and is discharged from the steam outlet. In addition, since the discharged steam is also cooled, safety during cooking is ensured.

以下、この貯留タンクの具体的構成を説明する。   Hereinafter, a specific configuration of the storage tank will be described.

貯留タンク13は、蓋体9に着脱自在に装着されて2個の圧力弁からのおねばを含む蒸気が送り込まれる下ケース14と、この下ケースの開口を覆う上ケース22とからなり、耐熱性の合成樹脂成型体で形成されている。これらの上下ケースは、二つ割りに分離できる構成となっている。この構成により、上下ケース14、22は別々に洗浄、乾燥ができるので、衛生的に管理ができる。この下ケース14は、上ケース22と組合されたときに、内部が水平方向に偏平状に広がった空室(空間)が形成されて、この空室は、おねばを分離するおねば分離室と、蒸気を一時溜め待機させる蒸気溜め室と、この蒸気溜め室で溜めた蒸気を外部排出する蒸気排出路とに区画されたものとなる。   The storage tank 13 includes a lower case 14 that is detachably attached to the lid body 9 and that is fed with steam that includes a meander from two pressure valves, and an upper case 22 that covers the opening of the lower case. It is made of a synthetic resin molding. These upper and lower cases can be separated into two. With this configuration, the upper and lower cases 14 and 22 can be cleaned and dried separately, so that they can be managed hygienically. When the lower case 14 is combined with the upper case 22, a vacant space (space) is formed in which the inside expands in a flat shape in the horizontal direction. And a steam storage chamber that temporarily stores and waits for steam, and a steam discharge passage that discharges the steam stored in the steam storage chamber to the outside.

下ケース14は、図6、図7に示すように、対向する一対の長辺及び短辺を有する横長矩形状の底板部14aと、この底板部の周囲から所定高さ立設された側板部14b〜14eと、側板部の頂部が開放されて底板部と対向する面に設けた開口14fとを有した浅底の容器で構成されている。側板部14b〜14eのうち、側板部14c〜14dは、底板部14aから略直角に立設した板状体からなり、一方の側板部14bは底板部から略弓形に湾曲して立設している。この側板部を湾曲させることによって、蓋体の外周の最端縁まで広げて内部空間を拡大できる。この下ケース14は、対向する一対の長辺及び短辺の底板部及び側板部で囲まれて内部に所定容積の空間が形成されている。この空間は、横方向、すなわち水平方向へ拡がった細長の直方体形状をなしている。   As shown in FIGS. 6 and 7, the lower case 14 includes a horizontally elongated bottom plate portion 14 a having a pair of opposed long sides and short sides, and a side plate portion erected at a predetermined height from the periphery of the bottom plate portion. 14b to 14e and a shallow container having an opening 14f provided on a surface opposed to the bottom plate part with the top part of the side plate part opened. Of the side plate portions 14b to 14e, the side plate portions 14c to 14d are formed of a plate-like body that is erected at a substantially right angle from the bottom plate portion 14a, and one side plate portion 14b is erected in a substantially arcuate shape from the bottom plate portion. Yes. By curving the side plate portion, the inner space can be expanded by extending to the outermost edge of the outer periphery of the lid. The lower case 14 is surrounded by a pair of opposed long and short side bottom plate portions and side plate portions, and a space of a predetermined volume is formed therein. This space has an elongated rectangular parallelepiped shape extending in the horizontal direction, that is, in the horizontal direction.

The Oneba recovery section S1 and the steam reservoir S2, is partitioned to the bottom plate portion 14a in the raised projections 14 1 predetermined by the height raised upward, the raised projections 14 1 and the ridge, collecting portion S1 if Ne each Contact And it becomes the inclined surface which descend | falls toward the steam reservoir S2. When the toy recovery part S1 and the steam storage part S2 are combined with the upper case 22, they form a toy separation room and a steam storage room.

おねば回収部S1は、比較的広い面積を有する窪みで構成されている。この回収部S1には、一方の長辺14b側を下方へ所定深さ凹ませて底部におねばを溜めるおねば溜め穴15を設けてある。この構成により、おねば回収部S1は、対向する一対の隆起突起141及び長辺部14b、14cからおねば溜め穴15に向かって下降した下降傾斜面を有した一種の如雨露となり、おねばがこの下降傾斜面に沿って流れ落ちておねば溜め穴15へ流れて回収される。おねば溜め穴15は、所定大きさの略円形の開口15aと、この開口から下方へ垂下した所定長さの筒状部15bと、この筒状部の開口を塞いだ底部15cとを有し、底部は所定面積を有している。この底部15cには、負圧弁16と、おねばを含む蒸気をタンク内へ導入する蒸気ガイド筒17とが設けられている。負圧弁16は、底部を貫通して設けられて、鍋内が負圧になったときに開き、おねば溜め穴15に溜まったおねばを鍋に戻す機能を備えたものとなっている。 If you ask, recovery part S1 is comprised by the hollow which has a comparatively large area. The collecting portion S1 is provided with a tortuous reservoir hole 15 in which one long side 14b side is recessed downward by a predetermined depth to collect a nebula at the bottom. This configuration Oneba collecting portion S1 becomes the opposing pair of raised projections 14 1 and the long side portion 14b, a type having a downwardly inclined surface which descends toward the reservoir hole 15 if Ne 14c Calao Watering, Oneba If it has flowed down along the descending inclined surface, it flows into the reservoir hole 15 and is collected. The pocket hole 15 has a substantially circular opening 15a having a predetermined size, a cylindrical portion 15b having a predetermined length hanging downward from the opening, and a bottom portion 15c blocking the opening of the cylindrical portion. The bottom has a predetermined area. The bottom portion 15c is provided with a negative pressure valve 16 and a steam guide cylinder 17 for introducing steam including a bowl into the tank. The negative pressure valve 16 is provided so as to penetrate the bottom portion, and has a function of opening when the inside of the pan becomes negative pressure and returning the trap accumulated in the trap reservoir 15 to the pan.

蒸気ガイド筒17は、一端が底部15cを貫通して開口が圧力弁に連通しており、他端が閉じられて内部が中空の筒状体からなり、底部15cから所定高さ、すなわち、上ケースに到達する長さに立設されている。この蒸気ガイド筒17は、頂部におねばを含む蒸気を噴射口18が設けられている。この噴射口18は、一方の長辺の側板部14cを向いて、その開口面積を大きく、すなわち、円周の半分以上の開口となっている。この開口は、略中央部を隔壁180で区切って、2つの開口181、182に分離するのが好ましい。すなわち、2つに分離することによって、おねばを含む蒸気を略2分して方向性を持たせて、上ケースの衝壁板部に衝突させて効率よく分散させることが可能になる。 The steam guide cylinder 17 has one end passing through the bottom portion 15c and the opening communicating with the pressure valve. The other end is closed and the inside is a hollow cylindrical body. It is erected to reach the case. The steam guide tube 17 is provided with an injection port 18 for steam containing a sprout at the top.

This opening is delimited substantially central portion in the partition wall 18 0, two openings 18 1, 18 preferably 2 to separate. That is, by separating into two, it becomes possible to distribute the steam efficiently, by causing the steam containing the rice bowl to divide into approximately two directions and to have a directivity, and to collide with the barrier plate portion of the upper case.

蒸気溜め部S2は、このおねば回収部S1の両側部にあって、おねばと蒸気とが回収部で分離されて、この分離された蒸気が一時待機して溜まるスペースとなっている。   The steam storage part S2 is located on both sides of the rice bowl recovery part S1, and is a space where the rice bowl and the steam are separated by the recovery part and the separated steam is temporarily stored.

下ケース14は、一方の長辺側板部14c側の内壁面側に、内壁面から所定距離離して、内壁面と略平行な隔壁板19が底板部から開口14fに向かって立設している。隔壁板19は、両蒸気溜め部S2に達し、短辺の側板部14d、14eとの間に隙間をあけて、細長の通路部S3が形成されている。この通路S3は上ケース22と組み合わせたとき蒸気排出路となる。   The lower case 14 is provided with a partition wall plate 19 standing on the inner wall surface on the side of the one long side plate portion 14c at a predetermined distance from the inner wall surface and substantially parallel to the inner wall surface from the bottom plate portion toward the opening 14f. . The partition plate 19 reaches both the vapor reservoirs S2, and a long and narrow passage portion S3 is formed with a gap between the side plates 14d and 14e on the short sides. This passage S3 becomes a steam discharge passage when combined with the upper case 22.

また、一方の長辺の側板部14cには、一対の係止部20a、20b及び他方の側板部14bに引掛け部21a、21bが所定距離離して設けられている。これらの一対の係止部及び引掛け部により、貯留タンク13が細長になるので安定した係合ができる。   The long side plate portion 14c is provided with a pair of latching portions 20a and 20b and the other side plate portion 14b with hook portions 21a and 21b separated by a predetermined distance. Since the storage tank 13 is elongated by the pair of locking portions and hooking portions, stable engagement can be achieved.

上ケース22は、図8、図9に示すように、対向する一対の長辺及び短辺を有する横長矩形状の天井部22aと、この天井板部の周囲から所定長さ垂下した側板部22b〜22eと、側板部の頂部が開放された底板部と対向する面に開口22fとを設け、下ケース14の開口14fを覆う大きさの浅底の容器で構成されている。側板部22b〜22eのうち、側板部22b〜22dは、底板部22aから略直角に立設した板状体からなり、一方の側板部22eは底板部から湾曲して立設している。なお、天井板部22aは、その外面22a’が化粧面となっている。天井板部には、図9に示すように、所定高さの分散・拡散部材24が下ケースに向かって垂下されている。この分散・拡散部材24は、下ケース14の筒状体頂部を囲むようにした枠壁板で構成されている。この枠壁板は、天井板部と一体成型により形成されている。この分散・拡散部材24は、噴射口からの蒸気が衝突して分散させる衝壁板部24aと、この衝壁板部24aに当たって所定の方向へ拡散させる一対の略平行に対向し所定長さの板材からなる略U字状の拡散板部24bとを有している。この拡散板部24bは、衝壁板部24aから離れるに従って天井板部から立設する高さを低くして、蒸気が衝壁板部24aに衝突した後に直ぐに広い範囲に拡散するように形成されている。上ケースは、その内部に通路に対応した箇所に直線状の蒸気口23が形成されている。この上ケース22は、対向する長辺の側板部22b、22cに引掛け部25、係止部26が設けられている。   As shown in FIGS. 8 and 9, the upper case 22 includes a horizontally-long rectangular ceiling portion 22 a having a pair of opposed long sides and short sides, and a side plate portion 22 b that is suspended from the periphery of the ceiling plate portion by a predetermined length. -22e and an opening 22f on a surface facing the bottom plate part where the top part of the side plate part is opened, and a shallow container having a size covering the opening 14f of the lower case 14. Of the side plate portions 22b to 22e, the side plate portions 22b to 22d are formed of a plate-like body erected substantially at a right angle from the bottom plate portion 22a, and one side plate portion 22e is erected in a curved manner from the bottom plate portion. The ceiling plate 22a has a decorative surface on the outer surface 22a '. As shown in FIG. 9, a dispersion / diffusion member 24 having a predetermined height is suspended from the ceiling plate portion toward the lower case. The dispersion / diffusion member 24 is composed of a frame wall plate that surrounds the top of the cylindrical body of the lower case 14. This frame wall board is formed by integral molding with the ceiling board part. The dispersion / diffusion member 24 includes a barrier plate 24a that collides and disperses the vapor from the injection port, and a pair of substantially parallel opposing and predetermined lengths that strike the barrier plate 24a and diffuse in a predetermined direction. And a substantially U-shaped diffusion plate portion 24b made of a plate material. The diffusion plate portion 24b is formed such that the height of the diffusion plate portion 24b standing from the ceiling plate portion decreases as the distance from the barrier plate portion 24a decreases, so that the steam diffuses in a wide range immediately after colliding with the barrier plate portion 24a. ing. The upper case is formed with a linear steam port 23 at a location corresponding to the passage. The upper case 22 is provided with a hooking portion 25 and a locking portion 26 on opposite side plates 22b and 22c on the long sides.

貯留タンク13の作用を説明する。沸騰維持工程において、一対の圧力弁が同時に開放されると、鍋内の圧力が高圧から略瞬時に大気圧近傍まで低下して、鍋内に激しい沸騰、すなわち突沸現象が発生して、炊飯物が鍋内で攪拌される。このとき、おねばを含んだ大量の蒸気が蒸気ガイド筒を通って、貯留タンク内へ入り込む。貯留タンク13へ入り込むと、二股に分かれた一対の噴射口から衝壁板部に向かって激しく衝突して、衝壁板部に沿って、内部へ入り込む。衝壁板部は、衝突部分とガイド面が幅狭になっているので、衝突した後は、直ちに分散、拡散される。この分散・拡散により、おねばは蒸気に比べて重いので、隆起突起を超えることが出来ずにおねば回収部で回収され、軽い蒸気は隆起突起の頂部を超えて、蒸気溜め部へ向かい、この蒸気溜め部で一時待機されてから通路を経て、蒸気排出通路を通過して蒸気口から外部へ放出される。   The operation of the storage tank 13 will be described. In the boiling maintenance process, when the pair of pressure valves are opened at the same time, the pressure in the pan drops from high pressure to near atmospheric pressure almost instantaneously, causing intense boiling in the pan, that is, a sudden boiling phenomenon, Is stirred in the pan. At this time, a large amount of steam containing rice balls passes through the steam guide tube and enters the storage tank. When entering the storage tank 13, it collides violently from the pair of bifurcated injection ports toward the barrier plate, and enters the interior along the barrier plate. Since the impact plate and the guide surface are narrow, the impact wall plate portion is immediately dispersed and diffused after the collision. Due to this dispersion / diffusion, the rice ball is heavier than the steam, so it cannot be over the raised protrusion and is collected in the collecting part, and the light steam goes over the top of the raised protrusion and heads to the steam reservoir, After temporarily waiting in this steam reservoir, it passes through the passage, passes through the steam discharge passage, and is discharged from the steam outlet to the outside.

この構成によれば、貯留タンクの容積は大きくされ、且つ偏平状の空室内でおねばを含む蒸気が一気に拡大分散されるので、おねばと蒸気とが効率よく分離される。また、おねば分離室で分離された蒸気が蒸気溜め室で一時待機して溜められ、冷却された後に蒸気排出路に入り込み、蒸気口から排出されるので、おねばが蒸気口から出てくることがなく、また、排出される蒸気も冷却されているため、炊飯時の安全性が確保される。また、貯留タンクは、圧力弁数の増加にしたがって容積を大きくしてあるので、おねばと蒸気とが効率よく分離され、より安全性が確保される。   According to this configuration, the volume of the storage tank is increased, and the steam containing the rice cake is expanded and dispersed all at once in the flat empty chamber, so that the rice cake and the steam are efficiently separated. In addition, the steam separated in the separation chamber is temporarily stored in the steam storage chamber, and after being cooled, enters the steam discharge path and is discharged from the steam outlet. In addition, since the discharged steam is also cooled, safety during cooking is ensured. In addition, since the storage tank has a larger volume as the number of pressure valves increases, the rice bowl and the steam are efficiently separated, and safety is further ensured.

貯留タンクには、大量のおねばが貯留されるので、この大量のおねばを鍋内へ略均等に分散するために、おねばシャワー板を使用する。   Since a large amount of rice cake is stored in the storage tank, a shower plate is used to distribute this large amount of rice cake into the pan almost evenly.

以下、図10を参照して、このおねばシャワー板を説明する。なお、図10はおねばシャワー板を示し、図10Aは正面図、図10Bは背面図、図10Cは図10AのXC−XCの断面図である。   Hereinafter, with reference to FIG. 10, this rice shower plate will be described. 10 shows a shower board, FIG. 10A is a front view, FIG. 10B is a rear view, and FIG. 10C is a cross-sectional view taken along XC-XC in FIG. 10A.

おねばシャワー板27は、圧力弁の数に対応してその面積を大きくする共に、おねば分散孔の数を多くした構成となっている。なお、従来のシャワー板は、おねば量が多くならないので、小径となっている(例えば、特許第4476306号参照)。   The shower plate 27 has a configuration in which the area is increased corresponding to the number of pressure valves and the number of dispersion holes is increased. In addition, since the amount of the conventional shower plate does not increase, it has a small diameter (for example, refer to Japanese Patent No. 4476306).

このおねばシャワー板27は、鍋の開口を略塞ぐ大きさ、すなわち、鍋開口の直径に近い直径及び所定肉厚の円形の皿状をなし金属板材の加工体で形成されている。このおねばシャワー板27は、貯留タンク13の負圧弁16の開成で落下するおねばを受容する受け領域27aと、この受け部の外周辺におねばを分散させるおねば分散領域27bとを有している。受け領域27aは、内蓋の負圧弁の略真下にあって小径の略円形の面積を有し、この小面積に数少ないおねば分散孔271が穿孔されている。おねば分散領域27bは、中心の受け領域27aを中心にして外方へ所定距離の同心円を描き、この同心円周上に複数個のおねば分散孔271が略等間隔に穿孔されている。同心円周部分を凹ませて、この凹み部におねば分散孔271を設けるのが好ましい。 The shower plate 27 has a size that substantially closes the opening of the pan, that is, a circular dish having a diameter close to the diameter of the pan opening and a predetermined thickness, and is formed of a metal plate processed body. The bed shower plate 27 has a receiving area 27a that receives a drop falling due to the opening of the negative pressure valve 16 of the storage tank 13, and a bed dispersion area 27b that distributes the bed around the outer periphery of the receiving section. is doing. Receiving area 27a has a substantially circular area of diameter be in substantially below the negative pressure valve of the inner lid, distribution holes 27 1 are perforated If Ne Contact few in this small area. Oneba dispersion region 27b is drawn a predetermined distance concentric outward around the center of the receiving area 27a, distribution holes 27 1 are perforated at substantially equal intervals when Ne plurality of contact on the concentric circle on. By recessing the concentric circumferential portion, preferably provided with distribution holes 27 1 if Ne apply in this recess.

このおねばシャワー板27は、鍋内が負圧になって、内蓋の負圧弁が開成して、おねばが落下すると、落下したおねばが中心の受け領域27aに溜まるが、この領域の面積が小さく且つおねば分散孔271数が少ないので、一部のおねばが鍋内へ滴下する。他のおねばは、おねば分散領域27bへ移動し、同心円周上に配設されたおねば分散孔271から順次鍋内へ滴下する。これにより、おねばは、略均一に鍋内へ分散されるので、美味しいご飯が炊き上がる。 When the inside of the pan becomes negative pressure and the negative pressure valve of the inner lid is opened and the rice bowl falls, the rice bowl is collected in the central receiving area 27a. Since the area is small and the number of dispersion holes 27 1 is small, some of the sticks drop into the pan. Other Oneba moves to Oneba dispersion region 27b, sequentially dropped into the pot from the distribution holes 27 1 If Ne Contact disposed concentrically circumference. As a result, rice balls are distributed almost uniformly in the pan, and delicious rice is cooked.
