It arrange | positions so that abutting is possible.
炊飯器本体１内には、各部及び各装置を駆動制御して炊飯動作を行う制御装置７が設置されている。制御装置７は、例えば蓋体３に設けられた操作スイッチから得られた指示に応じて、各部及び各装置の駆動制御を行い、炊飯加熱を実施する。 In the rice cooker main body 1, a control device 7 is installed that drives and controls each unit and each device to perform a rice cooking operation. The control apparatus 7 performs drive control of each part and each apparatus according to the instruction | indication obtained, for example from the operation switch provided in the cover body 3, and implements rice cooking heating.
炊飯器本体１の前壁上部（図１の左側上部）には、蓋体３のフック８に係合可能なフックレバー１ｂが設けられている。 A hook lever 1 b that can be engaged with the hook 8 of the lid 3 is provided on the upper part of the front wall of the rice cooker body 1 (upper left side in FIG. 1).
蓋体３には、略前方位置に蓋温度検知装置の一例である内蓋温度センサ９と、後方部分
に回動中心位置のヒンジ軸１０とが具備され、ヒンジ軸１０は回動自在に固定された蓋体３の開閉軸になっている。蓋体３はヒンジ軸１０の近傍に設けた回動バネ（図示せず）により回動する。また蓋体３の略中央に設けられた貫通孔３ａには、着脱自在にその空間内に嵌合固定される略円筒状の蒸気筒１１があり、その下端は内蓋４に面し、上端は蓋体３の外観面の一部としての形状を呈する。
The lid 3 is provided with an inner lid temperature sensor 9 which is an example of a lid temperature detecting device at a substantially forward position, and a hinge shaft 10 at the center of rotation at the rear portion, and the hinge shaft 10 is fixed rotatably. It is an opening / closing axis of the lid 3 made. The lid 3 is rotated by a rotation spring (not shown) provided in the vicinity of the hinge shaft 10. The through-hole 3a provided in the approximate center of the lid 3 has a substantially cylindrical steam cylinder 11 which is detachably fitted and fixed in the space, the lower end thereof faces the inner lid 4, and the upper end Exhibits a shape as a part of the appearance surface of the lid 3.
図２は、蒸気筒１１周辺の拡大図を表しており、蒸気筒１１は蒸気攪拌室１１ａ、蒸気筒蓋１１ｂ、蒸気通過部１１ｃなどで構成される。前記蒸気攪拌室１１ａは、鍋２内より発生する蒸気が入ってくる蒸気流入口１１ａ―１、軸受部１１ａ―２を有しており、前記軸受部１１ａ―２に回転自在に軸支されているのがファン１２である。ファン１２は前記蒸気流入口１１ａ―１に対向する位置に翼１２ａを備えている。ファン１２は例えばポリプロピレンのように耐蒸気性のある樹脂材料を成型して構成している。 FIG. 2 shows an enlarged view around the steam cylinder 11, and the steam cylinder 11 includes a steam stirring chamber 11a, a steam cylinder lid 11b, a steam passage portion 11c, and the like. The steam stirring chamber 11a has a steam inlet 11a-1 through which steam generated from the pot 2 enters and a bearing portion 11a-2, and is rotatably supported by the bearing portion 11a-2. The fan 12 is present. The fan 12 includes a blade 12a at a position facing the steam inlet 11a-1. The fan 12 is formed by molding a vapor-resistant resin material such as polypropylene.
軸受部１１ａ―２とファン１２内側との径方向の隙間を、片側０．２ｍｍに設定している。この隙間が０．０５ｍｍを下回ると、軸受け部１１ａ―２とファン１２内側が擦れてファン１２の回転に支障が発生、逆に隙間が０．５ｍｍを越えるとファン１２の回転がぶれて軸受け部１１ａ―２とファン１２内側とが衝突を繰り返し、衝突音による騒音が出てしまうため、隙間を詰めたほうが良い。 The radial gap between the bearing portion 11a-2 and the inside of the fan 12 is set to 0.2 mm on one side. If this gap is less than 0.05 mm, the bearing portion 11a-2 and the inside of the fan 12 rub against each other, causing trouble in the rotation of the fan 12. Conversely, if the gap exceeds 0.5 mm, the rotation of the fan 12 is shaken and the bearing portion. 11a-2 and the inside of the fan 12 repeatedly collide, and noise due to the collision sound is generated, so it is better to close the gap.
蒸気筒蓋１１ｂは蒸気通過部１１ｃ外周と溶着等で一体化され天面に蒸気排出口１１ｂ−１を有している。蒸気攪拌室１１ａと蒸気通過部１１ｃとを分割する壁１１ｃ−１には還流弁１３が設けられており、蒸気通過部１１ｃ側の圧力が上昇した時は還流弁１３が壁１１ｃ−１に押し当てられて蒸気の通過を塞ぎ、蒸気通過部１１ｃ側の圧力が下降した時は還流弁１３と壁１１ｃ−１との間に隙間が出来て蒸気攪拌室１１ａ内に入ったおねばが蒸気通過部１１ｃに滴下するようになっている。 The steam cylinder lid 11b is integrated with the outer periphery of the steam passage 11c by welding or the like and has a steam outlet 11b-1 on the top surface. A reflux valve 13 is provided on the wall 11c-1 that divides the steam stirring chamber 11a and the steam passage portion 11c, and when the pressure on the steam passage portion 11c side rises, the reflux valve 13 pushes against the wall 11c-1. When the pressure on the steam passage portion 11c side is lowered by being applied, a gap is formed between the reflux valve 13 and the wall 11c-1, and the rice cake that has entered the steam stirring chamber 11a passes through the steam. It is dripped at the part 11c.
図３は、ファン１２と蒸気流入口１１ａ―１との位置関係を下方より見た状態を示す部分断面図である。矢印は蒸気の流れとファン１２の回転方向を示す。
蒸気流入口１１ａ―１は、ファン１２の中央部に位置する筒形状に設けられた穴である。この数が２箇所以下だと、ファン１２に対して特定の箇所に集中的に蒸気が噴き出してファン１２がバランスを崩し、正常に回転しなくなる恐れがあるが、逆に蒸気流入口１１ａ―１の数が多いと蒸気流入口１１ａ―１の形状が複雑化してくるため、この場合には、３箇所設けている。
FIG. 3 is a partial cross-sectional view showing a state in which the positional relationship between the fan 12 and the steam inlet 11a-1 is viewed from below. The arrows indicate the flow of steam and the direction of rotation of the fan 12.
The steam inlet 11 a-1 is a cylindrical hole located in the center of the fan 12. If this number is 2 or less, steam may erupt intensively at a specific location with respect to the fan 12 and the fan 12 may be out of balance and may not rotate normally, but conversely, the steam inlet 11a-1 If the number is large, the shape of the steam inlet 11a-1 becomes complicated. In this case, three locations are provided.
一方、ファン１２に構成された翼１２ａは、図に示すように内側から外周に向けて放射方向から円周方向に変化していく略インボリュート曲線状になっており、この場合は５箇所装備されている。翼１２ａと蒸気流入口１１ａ―１との数を変えることで、ファン１２の回転方向の位置がどこにある時でも、翼１２ａに噴射された蒸気が当たって回動力に変換される位置関係となり、回動力を安定させている。 On the other hand, the blades 12a formed on the fan 12 have a substantially involute curve shape that changes from the radial direction to the circumferential direction from the inner side to the outer side as shown in the figure. ing. By changing the number of the blades 12a and the steam inlets 11a-1, regardless of the position of the fan 12 in the rotational direction, the steam injected into the blades 12a hits and is converted into rotational power. The rotational power is stabilized.
以上のように構成された炊飯器について、以下その動作、作用を説明する。 About the rice cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
まず、鍋２内に所定の米と水をセットし、炊飯工程が開始される。炊飯工程は、水を一定温度に保って米に水を吸収させる前炊き、鍋２を鍋加熱装置５により一気に加熱し、鍋２内の水を沸騰状態にする炊き上げ、鍋２内の水がほとんどなくなった状態で加熱を抑える蒸らしからなり、これらの工程の間に米の糊化を進めて炊飯する。制御装置７は鍋底センサ６により鍋２の温度に応じて最適に鍋加熱装置５を制御し、あらかじめ決められた炊飯プログラムに従って炊飯を行う。炊飯プログラムは米の種類などによって複数のコースが準備されている。この蒸らし工程が終了すると炊飯が終了し、自動的に保温工程へと移行し、炊き上がったご飯の温度が低下しないようにして、使用者がいつでも温かいご飯を
得られる。
First, predetermined rice and water are set in the pan 2, and the rice cooking process is started. In the rice cooking process, the water is kept at a constant temperature and cooked before the rice absorbs the water, the pot 2 is heated at once by the pot heating device 5, the water in the pot 2 is boiled, and the water in the pot 2 is boiled. It consists of steaming that suppresses heating in a state where there is almost no rice. During these steps, rice is gelatinized by proceeding with gelatinization. The control device 7 optimally controls the pan heating device 5 according to the temperature of the pan 2 by the pan bottom sensor 6, and cooks rice according to a predetermined rice cooking program. There are several courses in the rice cooking program depending on the type of rice. When this steaming process ends, cooking rice ends, and the process automatically shifts to a heat retaining process, so that the temperature of the cooked rice does not decrease, and the user can always obtain warm rice.
炊飯プログラム実行による動作の詳細を、図４をもとに、以下説明する。 The detail of the operation | movement by rice cooking program execution is demonstrated below based on FIG.
炊飯が開始されると、まず米に水を吸収させる前炊き工程が始まる。制御装置７は、鍋加熱装置５により鍋２を加熱し、鍋２内の水の温度を鍋底センサ５によって検知し、米の糊化が始まらない程度の温度（約６０℃未満）に調整して米の吸水を促進する。 When rice cooking is started, a pre-cooking process is first started in which the rice absorbs water. The control device 7 heats the pan 2 with the pan heating device 5, detects the temperature of the water in the pan 2 with the pan bottom sensor 5, and adjusts the temperature to a level at which rice gelatinization does not start (less than about 60 ° C.). Promote rice water absorption.
次に炊き上げに入る。炊き上げ初期の昇温工程では、米に水と熱を加えて糊化を進行させる。制御装置７は、鍋加熱装置５を動作させて鍋２を急速に加熱し、鍋２内の水を沸騰状態とする。次に沸騰維持工程に入るが、このとき連続的に沸騰が生じて蒸気が大量に発生する。発生した蒸気が鍋２を充満すると、余分な蒸気は蒸気筒１１に入り込み、蒸気通過部１１ｃや蒸気の流入口１１ａ―１を経て蒸気攪拌室１１ａ内に入り込む。蒸気筒内に流入する噴出力によりファン１２が回転する。 Then start cooking. In the temperature raising process at the initial stage of cooking, water and heat are added to the rice to advance gelatinization. The control device 7 operates the pan heating device 5 to rapidly heat the pan 2 to bring the water in the pan 2 to a boiling state. Next, the boiling maintenance process is started. At this time, boiling continuously occurs and a large amount of steam is generated. When the generated steam fills the pan 2, excess steam enters the steam cylinder 11, and enters the steam agitating chamber 11a through the steam passage 11c and the steam inlet 11a-1. The fan 12 is rotated by the jet power flowing into the steam cylinder.
沸騰維持工程では鍋加熱装置５に短時間単位での通電・停止が繰り返されるが、蒸気筒１１へ侵入した蒸気のうち、おねばを含む泡状の蒸気も鍋２内を満たすようになり、蒸気流入口１１ａ―１まで達するようになる。この時、蒸気流入口１１ａ―１を通り抜けた泡状のおねばは、蒸気攪拌室１１ａの中で風船状の泡となってそのまま蒸気排出口１１ｂ−１から外部へ抜け出そうとする。抜け出してしまうと、これがふきこぼれとなって蓋体３や炊飯器本体１を置いてある台上などを汚す事につながる。 In the boiling maintenance process, the pot heating device 5 is repeatedly energized and stopped in a short time unit, but among the steam that has entered the steam cylinder 11, the foamy steam including the rice cake also fills the pot 2. It reaches the steam inlet 11a-1. At this time, the bubble-like rice cake that has passed through the steam inlet 11a-1 becomes balloon-like bubbles in the steam agitating chamber 11a and tries to escape from the steam outlet 11b-1 as it is. If it comes out, this will be spilled and will lead to soiling the table on which the lid 3 and the rice cooker body 1 are placed.
本実施の形態では、蒸気攪拌室１１ａの中で風船状の泡となったおねばは、ファン１２の回転によりファン１２の翼１２ａがおねばの泡を切り裂いて潰す。おねばの泡が潰される事でおねばの風船が弾けて液状となり、蒸気攪拌室１１ａの下部に落とされて還流弁１３から蒸気通過部１１ｃに流れ落ち、更には鍋２内へ戻される。 In the present embodiment, the rice balls that have become balloon-like bubbles in the steam agitating chamber 11 a are crushed by the rotation of the fan 12 by the blades 12 a of the fan 12 smashing the bubbles. As the bubble of the rice ball is crushed, the ball of the rice ball is bounced to become liquid, dropped into the lower part of the steam stirring chamber 11a, flows down from the reflux valve 13 to the steam passage portion 11c, and is further returned to the pot 2.
このため、おねばは蒸気排出口１１ｂ−１には容易には届かず、ふきこぼれにならないため、その分鍋加熱装置５への通電時間を従来の炊飯器に比べて増やすことが可能となり、火通りの良い食味の優れた米飯を得ることができる。 For this reason, rice balls do not easily reach the steam outlet 11b-1 and do not spill over, so it is possible to increase the energization time to the pot heating device 5 as compared with the conventional rice cooker, You can get excellent cooked rice with good street taste.
以上のように、本発明にかかる炊飯器は、ふきこぼれ抑制機能に関するものであるので、他のふきこぼれが生ずる調理機器の用途にも適用できる。 As mentioned above, since the rice cooker concerning this invention is related with a spilling suppression function, it can be applied also to the use of the cooking appliance which another spilling occurs.
