Description

本発明は、米などを水とともに加熱・炊飯する無人自動炊飯装置に関するものである。より詳しくは、米の供給、洗浄、移送及び炊飯など全ての過程が人の手間をかけずに自動で行われるようにして、誰でも炊飯ができ、炊飯にかかる時間や手間を省くことができる無人自動炊飯装置に関する。   The present invention relates to an unattended automatic rice cooking apparatus that heats and cooks rice and the like with water. More specifically, all processes such as rice supply, washing, transfer, and rice cooking are performed automatically without human effort, and anyone can cook rice, saving time and time required for rice cooking. It relates to an unattended automatic rice cooker.

一般に炊飯のためには、人が直接米びつから米を取り出して容器に盛り、水で数回研いだ後、一般の電気炊飯器や圧力炊飯器に移し盛り、加熱手段により加熱して炊飯する。   In general, for rice cooking, a person directly takes out rice from the rice bin, pours it into a container, sharpens it with water several times, transfers it to a general electric rice cooker or pressure rice cooker, and heats it with heating means to cook rice.

従来の炊飯方法は、人が直接米びつから米を取り出して容器に盛って研ぎ、炊飯のみ電気炊飯器などによって行うので、共稼ぎ夫婦や独り者及び老弱者、子供などは定時に飯を炊いて食べにくいという問題がある。そこで、前記問題を解決するために、米びつと炊飯器とを組み合わせた技術が多様に開発されてきた。最近、米びつから定量で米を供給し、供給された米を洗米手段によって洗浄し、洗浄された米と水とを加熱手段に移送して炊飯する一連の過程を無人で行う無人自動炊飯装置が多数開発された、あるいは、開発中である。   The traditional rice cooking method is that people take rice directly from the rice bin and sharpen it in a container, and only cook rice with an electric rice cooker, etc. There is a problem. Therefore, in order to solve the above-mentioned problems, various techniques have been developed that combine rice bins and rice cookers. Recently, unattended automatic rice cooking equipment that supplies rice in a fixed amount from rice bins, cleans the supplied rice with rice washing means, transfers the washed rice and water to heating means and cooks rice unattended, unattended Many have been developed or are under development.

しかし、既存の無人自動炊飯装置は、その構造が複雑であり、回転ブレードなどの洗米手段の作動によって洗米するとき米の胚芽などが損傷され栄養素が破壊される短所を有しており、米びつから洗米手段へと米を下部に供給して洗米後、洗米手段から洗米手段の下に位置した飯釜へと米を下部に供給するために上下方向に長く形成されるのでシンク台やテーブルに載せておくことが難しい。そして、飯釜の着脱を繰り返すと炊飯器と本体との間の結合部が壊れやすいので装置の寿命が短縮されるなど多くの問題を有している。このような理由から、既存の無人自動炊飯装置の大多数が製品化されていない。製品化された炊飯装置の場合にも頻繁な故障によるアフターサービスなどの問題で量産化できていないので、製品の供給が需要に追いつかず広く商用化されていないのが現況である。   However, the existing unattended automatic rice cooker has a complicated structure and has the disadvantage that the rice germ is damaged and the nutrients are destroyed when the rice is washed by the operation of the rice washing means such as a rotating blade. After the rice is supplied to the bottom of the rice washing means and washed, it is formed long in the vertical direction to feed the rice from the rice washing means to the rice cooker located under the rice washing means, so it is placed on a sink or table. It is difficult to keep. When the rice cooker is repeatedly attached and detached, the connecting portion between the rice cooker and the main body is easily broken, so that there are many problems such as shortening the life of the apparatus. For these reasons, the majority of existing unattended automatic rice cookers have not been commercialized. Even commercialized rice cookers have not been mass-produced due to problems such as after-sales service due to frequent failures, and the current situation is that the supply of products cannot keep up with demand and are not widely commercialized.

このような既存の無人自動炊飯装置の諸問題を解決するために、本発明者は、改良された無人自動炊飯装置を特許文献１に開示した。しかし、上記技術は、洗米手段が横方向に形成されて洗浄された米を飯釜に完全に供給するのに長い時間がかかる、洗浄槽に連結された供給ホースが水圧に耐えられなくて勝手に水が供給される、取っ手上の開閉板がスライドされ一側に長く突出して飯釜の蓋の把持が困難である、及び、本体と飯釜との連結部である移送管の端部にスプリングによって弾性支持される弾性支持具が飯釜と本体との結合時に騒音を発生させるなど多数の短所を有している。これを解決するために、本発明者は、さらに改良された無人自動炊飯装置を特許文献２に開示した。しかし、特許文献２に開示された無人自動炊飯装置も、供給ホースから供給される洗浄水が洗浄槽の一側から供給されて、米の洗浄時に洗浄槽の壁面に米が乾きながらくっつき、水位レベルセンサーによって洗浄槽内に供給される水の量を制御するときの精度が落ち、排出口と移送管とを通じて飯釜に米を供給するとき飯釜の中央部にのみ積もって米が不安定な位置に置かれるなど多数の短所を有している。   In order to solve the problems of such an existing unattended automatic rice cooker, the present inventor disclosed in Patent Document 1 an improved unattended automatic rice cooker. However, the above technique requires a long time to completely supply the washed rice with the rice washing means formed in the horizontal direction, and the supply hose connected to the washing tank cannot withstand the water pressure. Water is supplied to the handle, the opening / closing plate on the handle is slid and protrudes long on one side, and it is difficult to grip the lid of the rice cooker, and at the end of the transfer pipe that is the connection between the main body and the rice cooker An elastic support that is elastically supported by a spring has a number of disadvantages such as generation of noise when the pot is connected to the main body. In order to solve this problem, the present inventor has disclosed a further improved unmanned automatic rice cooking apparatus in Patent Document 2. However, the unmanned automatic rice cooking device disclosed in Patent Document 2 is also supplied with washing water supplied from the supply hose from one side of the washing tank, and when the rice is washed, the rice sticks to the wall of the washing tank while drying, The accuracy when controlling the amount of water supplied to the washing tank by the level sensor is reduced, and when rice is fed to the rice kettle through the discharge port and the transfer pipe, the rice is unstable only by accumulating in the central part of the rice kettle It has a number of disadvantages such as being placed in various locations.

上記本発明者の特許文献１及び２はともに、米びつに米を保管するとき一定時間が経つと米に虫や有害細菌が発生するので非衛生的であり、使用者が飯釜を本体の飯釜挿入部に据え置くか持ち出すときに、飯釜挿入部に飯釜がひっかかるか熱い飯釜により使用者が危なくなる。そして、モーターによって回転される米供給手段は、円形板上に放射状に一定の間隔で形成された多数の固定された定量供給孔を備えるため、洗浄槽への米の供給が長くかかり米びつの米が洗浄槽に供給されるとき連続的な供給が不可能である。また、洗浄槽の水分の逆流により固定された定量供給孔の周縁に米がくっつく、あるいは、米びつの内部に有害細菌の繁殖及び悪臭を誘発するなど多くの問題を有している。   Both the above Patent Documents 1 and 2 of the present inventor are unhygienic because insects and harmful bacteria are generated in the rice after a certain period of time when the rice is stored in the rice bin. When placed on or taken out from the hook insertion section, the pot is caught in the pot insertion section or hot cooker makes the user unsafe. The rice supply means rotated by the motor has a large number of fixed quantitative supply holes formed radially at regular intervals on the circular plate, so that it takes a long time to supply the rice to the washing tank and the rice When is supplied to the washing tank, continuous supply is not possible. In addition, there are many problems such as rice sticking to the periphery of the fixed-quantity supply hole fixed by the backflow of water in the washing tank, or breeding of harmful bacteria and malodor inside the rice bin.

It is activated through the process of Accordingly, the unmanned automatic rice cooker 1 according to the present invention does not have to perform the cumbersome work that the user has to wash and transfer the rice several times, and at the desired time by pressing the button on the control panel 3. The rice can be obtained automatically and you can eat regularly even in a busy day.

以下、本発明による無人自動炊飯装置１の各部品ごとの作用をより詳しく説明する。   Hereinafter, the effect | action for every component of the unmanned automatic rice cooking apparatus 1 by this invention is demonstrated in detail.

まず、米びつ１０は、紫外線及び遠赤外線を放出して殺菌効果を提供する紫外線ランプ１４と炭１５とを含むので、米びつ１０に米が長期間保管されていても米虫などの虫類や有害な有害細菌が生息できないため、炊飯装置１がより安全で衛生的である。洗浄槽３０への米の供給部分を見ると、米びつ１０の米が傾斜型ホッパー１２の内面に沿って供給口１３を通じて米供給手段２０のケーシング２１の投入孔２１ｃに投入される際、ベルトコンベヤ２６の支持板２５によって区画された空間または移送スクリュー２６’の下部に米が供給される。ベルトコンベヤ２６または移送スクリュー２６’がモーター２２によって回転される際、米投入管３１を通じて洗浄槽３０に米が供給される。従って、米はベルトコンベヤ２６または移送スクリュー２６’とによって連続的に供給され、より迅速に供給できる。   First, since the rice bottle 10 includes an ultraviolet lamp 14 and charcoal 15 that emit ultraviolet rays and far infrared rays to provide a sterilizing effect, even if the rice is stored in the rice bottle 10 for a long period of time, insects such as rice insects and harmful Since no harmful bacteria can live, the rice cooker 1 is safer and more hygienic. When the rice supply portion to the washing tank 30 is viewed, when the rice in the rice bottle 10 is introduced into the introduction hole 21c of the casing 21 of the rice supply means 20 through the supply port 13 along the inner surface of the inclined hopper 12, the belt conveyor. The rice is supplied to the space defined by the 26 support plates 25 or the lower part of the transfer screw 26 ′. When the belt conveyor 26 or the transfer screw 26 ′ is rotated by the motor 22, rice is supplied to the washing tank 30 through the rice charging pipe 31. Therefore, the rice is continuously supplied by the belt conveyor 26 or the transfer screw 26 'and can be supplied more rapidly.

このとき、モーター２２の駆動軸２３または駆動軸２３に固定された回動板２９が回動される際、回動板２９上に放射状に位置した感知孔２９ａが回動位置を感知するので、コントロールパネル３に設定された人数に合わせた正確な量の米が洗浄槽３０に供給される。このとき、ベルトコンベヤ２６は、ケーシング２１の内部両側に形成された一対の支持突起２１ｄによって支持され、固定片２７に装着されたテンション調節ボルト２８は従動軸２４が長孔２１ａに沿って上に上昇するように操作されてテンションを調節することでベルトコンベヤ２６の垂れなどを防止することができる。   At this time, when the rotation shaft 29 of the motor 22 or the rotation plate 29 fixed to the drive shaft 23 is rotated, the detection holes 29a radially located on the rotation plate 29 detect the rotation position. An accurate amount of rice according to the number of people set in the control panel 3 is supplied to the washing tank 30. At this time, the belt conveyor 26 is supported by a pair of support protrusions 21d formed on both inner sides of the casing 21, and the tension adjusting bolt 28 attached to the fixed piece 27 has the driven shaft 24 moved upward along the long hole 21a. The belt conveyor 26 can be prevented from dripping by adjusting the tension by being operated so as to rise.

米供給手段２０によって米が米投入管３１側に供給されると直ちに、スプリング１０４によって吐出口２１ｂを閉鎖していた開閉板１０３が米供給手段２０の作動と同時に電気の印加で磁気化されたコア１０５ａを備えるソレノイド１０５
の方にくっつく。次に、吐出口２１ｂは開放され、それによって米は米投入管３１を通じて洗浄槽３０に供給される。米供給手段２０による米の供給終了と同時にソレノイド１０５は磁力を失ってスプリング１０４の復元力によって支持板１０２のラウンド型ヒンジ部１０２ａを基点にして角運動されることで、吐出口２１ｂは閉鎖されて洗浄槽３０内部の水分が米供給手段２０に逆流することを防止する。 As soon as rice is supplied to the rice input pipe 31 by the rice supply means 20, the opening / closing plate 103 that has closed the discharge port 21 b by the spring 104 is magnetized by the application of electricity simultaneously with the operation of the rice supply means 20. Solenoid 105 having a core 105a
Stick to the person. Next, the discharge port 21 b is opened, whereby rice is supplied to the cleaning tank 30 through the rice input pipe 31. Simultaneously with the end of rice supply by the rice supply means 20, the solenoid 105 loses its magnetic force and is angularly moved with the restoring force of the spring 104 as a starting point from the round hinge 102a of the support plate 102, thereby closing the discharge port 21b. Thus, the water in the washing tank 30 is prevented from flowing back to the rice supply means 20.

定められた量の水は、米びつ１０の傾斜型ホッパー１２の外側下部に位置された洗浄水貯蔵槽７０に、供給ホース７２を通じて外部から水量制御手段７４によって供給され、貯蔵される。貯蔵された洗浄水は、米供給手段２０によって供給ホース４を通じて供給された米が盛られた洗浄槽３０に、流量制御弁３２によって一定時間稼動されたポンプ４ａによって供給される。その後、円筒状洗浄槽３０のハウジング３０ａの上部に固定された洗米手段４０の駆動モーター４１が回転される。駆動軸４２と駆動軸４２に固定された支持台４３・４４・４５が回転されながら、第１支持台４３の傾いた内側ブレード４３ａは米を洗浄槽３０の中央から外側に掃き出し、第３支持台４５に一体で傾斜して形成された外側ブレード４５ａは米を中間支持台４３側に内側に掃き、第２支持台４４の中間ブレード４４ａは回転しながら洗浄槽３０底の中間部分にある米を掃き出す。これにより、米が内側、中間、外側ブレード４３ａ・４４ａ・４５ａによって擦られて洗浄される。このような過程を繰り返すことで、本発明による無人自動炊飯装置は米の胚芽などの栄養素を破壊することなく洗米できる。このとき内側ブレード４３ａおよび中間ブレード４４ａは、非常に低く形成されるので米の胚芽の損傷を減少させるとともに駆動モーター４１の過負荷も顕著に減少させる。ブレード４３ａ・４４ａ・４５ａは５〜８回回転して一回の洗浄が完了する。以後、排水口３３に位置した遮断板３７はモーター３６によってスライドされ、遮断板３７の貫通孔３８は排水口３３と一致している。水は排水管３３ａを通じて外部に排水されるが、このときフィルターネット３４が排水口３３に装着されているので、米は濾過され水だけ排水される。   A predetermined amount of water is supplied and stored by the water amount control means 74 from the outside through the supply hose 72 to the washing water storage tank 70 located at the lower outside of the inclined hopper 12 of the rice bin 10. The stored washing water is supplied to the washing tank 30 in which the rice supplied by the rice supply means 20 through the supply hose 4 is accumulated by the pump 4a operated for a predetermined time by the flow control valve 32. Then, the drive motor 41 of the rice washing means 40 fixed to the upper part of the housing 30a of the cylindrical washing tank 30 is rotated. While the drive shaft 42 and the support bases 43, 44, and 45 fixed to the drive shaft 42 are rotated, the inclined inner blade 43a of the first support base 43 sweeps rice out from the center of the cleaning tank 30 to the third support. The outer blade 45a formed integrally and inclined on the table 45 sweeps the rice inward toward the intermediate support table 43, and the intermediate blade 44a of the second support table 44 rotates while the rice is in the middle portion of the bottom of the washing tank 30. Sweep out. As a result, the rice is rubbed and cleaned by the inner, middle and outer blades 43a, 44a and 45a. By repeating such a process, the unmanned automatic rice cooker according to the present invention can wash rice without destroying nutrients such as rice germ. At this time, the inner blade 43a and the intermediate blade 44a are formed to be very low, so that damage to rice germ is reduced and the overload of the drive motor 41 is also significantly reduced. The blades 43a, 44a, and 45a are rotated 5 to 8 times to complete one cleaning. Thereafter, the blocking plate 37 positioned at the drain port 33 is slid by the motor 36, and the through hole 38 of the blocking plate 37 coincides with the drain port 33. The water is drained to the outside through the drain pipe 33a. At this time, since the filter net 34 is attached to the drain port 33, the rice is filtered and only the water is drained.

洗米手段４０によって２〜３回洗浄が終わった後、排水口３３は遮断板３７によって遮断され、きれいな水が供給ホース４を通じて洗浄槽３０に再供給される。このとき、コントロールパネル３で設定された米の量に応じて炊飯するのに適量の水が供給される。定められた量の水が完全に供給された後、流量制御弁３２によってそれ以上の水は供給されない。水が供給された後、排出口３５の遮断板３７がモーター３６によってスライドされ遮断板３７の貫通孔３８が排出口３５と一致すると、洗浄された米ときれいな水とが移送管９を通じて飯釜５０に移送される。このとき移送管９の下端に装着された拡散手段９０によって飯釜本体５１の底に米が均一に広げられる。   After the washing is completed 2-3 times by the rice washing means 40, the drain port 33 is blocked by the blocking plate 37, and clean water is supplied again to the washing tank 30 through the supply hose 4. At this time, an appropriate amount of water is supplied to cook rice according to the amount of rice set in the control panel 3. After the prescribed amount of water is completely supplied, no further water is supplied by the flow control valve 32. After the water is supplied, when the blocking plate 37 of the discharge port 35 is slid by the motor 36 and the through hole 38 of the blocking plate 37 coincides with the discharge port 35, the washed rice and clean water are transferred through the transfer pipe 9 to the rice pot. 50. At this time, the rice is evenly spread on the bottom of the cooker body 51 by the diffusion means 90 attached to the lower end of the transfer pipe 9.

このとき、洗浄槽３０内の米と水とを排出口３５に完全に排出するために回転する内側、中間、外側ブレード４３ａ・４４ａ・４５ａに形成されたスクレーパー４７によってハウジング３０ａの壁面と底面との間に空間が存在しないので、この空間に米粒が挟まることが防止される。スクレーパー４７は洗浄槽３０の壁面と底面に付着された米を排出口３５に押し出して、米をより迅速且つ正確に排出口３５に排出する。また、供給ホース４から供給された水は洗浄水噴射手段４６によってハウジング３０ａの壁面とブレード４３ａ・４４ａ・４５ａの壁面に均一に噴射されるので、米粒が全部排出口３５に排出できる。また、米が飯釜５０に排出される間に水は洗浄水噴射手段４６の噴射孔４６ａを通じてゆっくり噴射される。米が完全に排出されるときに合わせて水の供給も終わらせることが望ましい。洗浄槽３０の底面中央に傾斜面部３０ｂが形成され、水や米が排水口３３及び排出口３５が形成された周縁側によく流れるようにする。   At this time, the wall surface and bottom surface of the housing 30a are formed by the scrapers 47 formed on the inner, middle and outer blades 43a, 44a, and 45a that rotate to completely discharge the rice and water in the cleaning tank 30 to the discharge port 35. Since there is no space between them, rice grains are prevented from being caught in this space. The scraper 47 pushes the rice adhering to the wall surface and bottom surface of the cleaning tank 30 to the discharge port 35, and discharges the rice to the discharge port 35 more quickly and accurately. Further, since the water supplied from the supply hose 4 is uniformly sprayed to the wall surface of the housing 30a and the wall surfaces of the blades 43a, 44a, and 45a by the cleaning water spraying means 46, all the rice grains can be discharged to the discharge port 35. Further, while the rice is discharged into the pot 50, water is slowly injected through the injection hole 46a of the washing water injection means 46. It is desirable to end the water supply when the rice is completely discharged. An inclined surface portion 30b is formed at the center of the bottom surface of the cleaning tank 30 so that water and rice flow well to the peripheral side where the drain port 33 and the discharge port 35 are formed.

排水口３３と排出口３５の開閉を制御する遮断板３７は、遮断板３７に連結された連結バー３７’の他側が連結されたカム３６’の偏心回転によってスライドされる。モーター回転時カム３６’は偏心回転し、遮断板３７は連結バー３７’によって案内溝３０ｃ上でスライドされる。排水口３３や排出口３５の遮断板３７の開閉動作は、開閉感知センサー３７ａがカム３６’の移動を感知した後、定められた順序に従って順次行われる。   The blocking plate 37 that controls the opening and closing of the drain port 33 and the discharge port 35 is slid by the eccentric rotation of the cam 36 ′ connected to the other side of the connecting bar 37 ′ connected to the blocking plate 37. When the motor rotates, the cam 36 'rotates eccentrically, and the blocking plate 37 is slid on the guide groove 30c by the connecting bar 37'. The opening / closing operation of the blocking plate 37 of the drain port 33 and the discharge port 35 is sequentially performed according to a predetermined order after the opening / closing detection sensor 37a detects the movement of the cam 36 '.

洗浄槽３０内部の米が洗米手段４０によって完全に洗浄され、飯釜５０への米と水との供給が完全に終わってから、洗浄槽３０のハウジング３０ａの上部一側に装着された送風機１１０は洗浄槽３０内部に風を供給するように作動する。このとき、送風機１１０の下部に位置した熱線部１１１によって熱風供給管３０’を通じて熱風が供給されるため、洗浄槽３０の内部を乾燥させることで、本発明は水分による細菌及びかびなどの生息を防止することができる。   The rice blower 110 mounted on the upper side of the housing 30a of the washing tank 30 after the rice inside the washing tank 30 is completely washed by the rice washing means 40 and the rice and water are completely supplied to the rice pot 50. Operates to supply air into the cleaning bath 30. At this time, since hot air is supplied through the hot air supply pipe 30 ′ by the hot wire portion 111 located at the lower part of the blower 110, the present invention can prevent the presence of bacteria and fungi due to moisture by drying the inside of the washing tank 30. Can be prevented.

米と水とが移送管９と飯釜の蓋５２の突出部５３のスライド孔５４を通じて飯釜５０に完全に移送される際、排出口３５の遮断板３７は角運動する。従って、排出口３５が閉鎖された状態で飯釜５０が据え置きされた飯釜据置台６１の飯釜挿入孔６７の下部に位置した加熱手段６０に電気が加えられて、電気により加熱手段６０が熱を発生させて炊飯を完了する。飯釜本体５１が加熱手段６０に据え置きされる際、突出具６９ａは下向きに加圧され、感知センサー６９ｂはこれを感知して加熱手段６０に電気を供給する。従って、本発明による無人自動炊飯装置１は、飯釜本体５１が加熱手段６０に据え置きされていない状態では何の作動もしないため、優れた安全性を提供する。   When the rice and water are completely transferred to the cooker 50 through the transfer tube 9 and the slide hole 54 of the protrusion 53 of the cooker lid 52, the blocking plate 37 of the discharge port 35 is angularly moved. Accordingly, electricity is applied to the heating means 60 located at the lower portion of the rice pot insertion hole 67 of the rice pot mounting table 61 on which the rice pot 50 is fixed in a state where the discharge port 35 is closed, and the heating means 60 is caused by electricity. Generate heat and complete cooking. When the rice pot main body 51 is placed on the heating means 60, the protrusion 69a is pressurized downward, and the sensing sensor 69b senses this and supplies electricity to the heating means 60. Therefore, the unmanned automatic rice cooker 1 according to the present invention does not operate in a state where the cooker main body 51 is not placed on the heating means 60, and thus provides excellent safety.

そして、加熱手段６０によって加温された飯釜５０の内部に蒸気が発生すれば、最初には飯釜の蓋５２の自重によって蒸気が外部に排出されない。しかし、ある程度の時間が経てば、蒸気が多く発生して飯釜５０の内部圧力が高くなる。従って、圧力が飯釜の蓋５２の重量より大きくなれば、安全弁５６の圧力錘５８が上昇し、蒸気排出片５７の蒸気排出孔５７ａが開放されて、蒸気が圧力錘５８の噴出孔５８ａを通じて飯釜５０の外部に排出される。このとき、安全弁５６を通じて排出される蒸気は飯釜挿入部８上部の本体２に設けられた蒸気排出口９１を通じて無人自動炊飯装置１から大気中に排出される。安全弁５６を通じて排出されなかった一部の蒸気は飯釜本体５１の上部に形成された蒸気滞留溝５１ｂ上に滞留されることで、本発明による無人自動炊飯装置は適当な蒸気圧力によってよく炊けたおいしい飯を提供することができる。   If steam is generated inside the pot 50 heated by the heating means 60, the steam is not discharged to the outside by the weight of the lid 52 of the pot first. However, when a certain amount of time has passed, a lot of steam is generated and the internal pressure of the pot 50 increases. Accordingly, when the pressure becomes larger than the weight of the lid 52 of the pot, the pressure weight 58 of the safety valve 56 rises, the steam discharge hole 57a of the steam discharge piece 57 is opened, and the steam passes through the ejection hole 58a of the pressure weight 58. It is discharged outside the pot 50. At this time, the steam discharged through the safety valve 56 is discharged from the unmanned automatic rice cooker 1 into the atmosphere through the steam discharge port 91 provided in the main body 2 above the pot insertion portion 8. Part of the steam that has not been discharged through the safety valve 56 is retained in a steam retention groove 51b formed in the upper portion of the rice cooker body 51, so that the unmanned automatic rice cooker according to the present invention can be cooked well with an appropriate steam pressure. Delicious rice can be provided.

上記炊飯方法で炊飯が完了すれば、使用者は飯釜本体５１を無人自動炊飯装置１から分離して飯を食べれば良い。図２１のように、無人自動炊飯装置１から飯釜本体５１を分離する時、ピニオンギア６５は本体２の下部に形成されたスライド凹部６４’の前方に固定された正逆駆動モーター６６によって回転される。ピニオンギア６５が回転すると、ピニオンギア６５に歯車結合されたラックギア６４の固定された飯釜据置台６１が案内凹部６２に結合された左右ガイドバー６３に沿ってスライドされて自動で引き出される。このとき、前方ローラー６２ａは案内凹部６２の上面部と接し、左右ガイドバー６３の前方に回転自在に結合される。後方ローラー６２ｂは、ガイド溝６３ａに結合され左右ガイドバー６３の後方に回転自在に装着されるため、飯釜据置台６１は左右にそれることなく、より容易に引き出しできる。後方ローラー６２ｂはガイド溝６３ａの前側ストッパー突起６３ｂによって本体２から完全に脱離されないため、飯釜据置台６１はガイドバー６３上で自動で出入りすることができ、ガイドバー６３は支持板６３’によって本体２上により堅固に固定される。   If rice cooking is completed by the above rice cooking method, the user may separate the rice pot main body 51 from the unmanned automatic rice cooking apparatus 1 and eat the rice. As shown in FIG. 21, when separating the pot main body 51 from the unmanned automatic rice cooker 1, the pinion gear 65 is rotated by a forward / reverse drive motor 66 fixed in front of a slide recess 64 ′ formed in the lower part of the main body 2. Is done. When the pinion gear 65 rotates, the cooker table 61 to which the rack gear 64 fixed to the pinion gear 65 is fixed is slid along the left and right guide bars 63 connected to the guide recess 62 and automatically pulled out. At this time, the front roller 62 a is in contact with the upper surface portion of the guide recess 62 and is rotatably coupled to the front of the left and right guide bars 63. Since the rear roller 62b is coupled to the guide groove 63a and is rotatably mounted behind the left and right guide bars 63, the rice pot mounting table 61 can be pulled out more easily without deviating left and right. Since the rear roller 62b is not completely detached from the main body 2 by the front stopper projection 63b of the guide groove 63a, the rice pot mounting table 61 can automatically enter and exit on the guide bar 63, and the guide bar 63 is supported by the support plate 63 ′. Is more firmly fixed on the main body 2.

飯釜据置台６１が引き出された後、使用者がまずコントロールパネル３の保温や炊飯状態を取り消すボタンを押せば、飯釜の蓋５２は昇降調節装置８０によって自動で上昇される。以後、飯釜据置台６１は、正逆駆動モーター６６のピニオンギア６５の正逆回転によってガイドバー６３に沿ってスライド引き出しされる。飯釜本体５１が飯釜挿入孔６７に据え置きされた後、使用者が炊飯ボタンを押せば、正逆駆動モーター６６が自動で逆回転し飯釜据置台６１は飯釜挿入部８に完全に結合される。次いで、飯釜挿入検知センサー６４ａは飯釜据置台６１と飯釜挿入部８との結合を感知し、以後の動作が行われる。従って、本発明による無人自動炊飯装置１は、使用者が熱い飯釜５０を飯釜挿入部８から直接持ち出さなくても良いので、使用者に使用上の便宜性を提供し安全性を極大化させたものである。   When the user first presses a button for canceling the heat insulation or cooking state of the control panel 3 after the cooker table 61 is pulled out, the lid 52 of the cooker is automatically raised by the lifting / lowering adjustment device 80. Thereafter, the pot pot 61 is slid out along the guide bar 63 by forward and reverse rotation of the pinion gear 65 of the forward / reverse drive motor 66. After the rice cooker body 51 is placed in the rice cooker insertion hole 67, if the user presses the rice cooking button, the forward / reverse drive motor 66 automatically rotates in the reverse direction, and the rice cooker table 61 is completely attached to the rice cooker insertion portion 8. Combined. Next, the pot insertion detection sensor 64a senses the coupling between the pot setting table 61 and the pot insertion portion 8, and the subsequent operation is performed. Therefore, the unmanned automatic rice cooker 1 according to the present invention does not require the user to take out the hot rice cooker 50 directly from the rice cooker insertion portion 8, thus providing convenience for the user and maximizing safety. It has been made.

図１８のように、上述の飯釜の蓋５２が上に上昇するときにはカム８４がモーター８６の回転によって回動し、カム８４と一端が接するスライダー８２はガイダー８３の案内溝８３ａ上で上部にスライドされる。従ってスライダー８４が固定された固定具８１の上昇によって、飯釜の蓋５２全体が移送管９に沿って上に上昇することになる。飯釜の蓋５２の下降時には上昇動作とは反対に、図１９のようにカム８４がモーター８６の回転によって回動すると、スライダー８２がガイダー８３の案内溝８３ａ上で下部にスライドされ、飯釜の蓋５２は自重によって下部に牽引される。飯釜の蓋５２の昇降時に、垂直スライドするスライダー８２の最上点と最下点にそれぞれ装着された位置感知センサー８７は飯釜の蓋５２の昇降を感知し信号を電子コントロール装置に送ってコントロールパネル３を操作することができる。飯釜の蓋５２のスライド孔５４の内面上部に固定されたテフロンパッキング５５はスライダー８２が移送管９に沿ってスライドするとき、騒音発生を抑制すると同時に飯釜５０内部の蒸気漏出を防止する。他の実施形態に従って、飯釜の蓋５２はカム８４の代わりにモーター８６の軸８５に装着されたピニオンギア８８と、スライダー８２に装着されピニオンギア８８と歯車結合されたラックギア８９との間の相互作用によって昇降できる。   As shown in FIG. 18, when the above-mentioned pot lid 52 is raised, the cam 84 is rotated by the rotation of the motor 86, and the slider 82 contacting one end of the cam 84 is located above the guide groove 83 a of the guider 83. Slide. Therefore, as the fixture 81 to which the slider 84 is fixed rises, the entire lid 52 of the rice pot rises along the transfer pipe 9. As shown in FIG. 19, when the pot 52 is lowered, when the cam 84 is rotated by the rotation of the motor 86, the slider 82 is slid downward on the guide groove 83a of the guider 83. The lid 52 is pulled downward by its own weight. When the pot 52 is moved up and down, the position sensor 87 attached to the uppermost point and the lowermost point of the slider 82 that slides vertically senses the movement of the pot 52 and sends a signal to the electronic control device. The panel 3 can be operated. The Teflon packing 55 fixed to the upper part of the inner surface of the slide hole 54 of the lid 52 of the rice cooker suppresses the generation of noise when the slider 82 slides along the transfer pipe 9 and at the same time prevents the steam leakage inside the rice cooker 50. According to another embodiment, the pot lid 52 is between a pinion gear 88 mounted on the shaft 85 of the motor 86 instead of the cam 84 and a rack gear 89 mounted on the slider 82 and geared to the pinion gear 88. It can be moved up and down by interaction.

一方、豆、麦、きび、粟などの穀物及び米と混合された雑穀を米の代わりに用いてもよい。このために、雑穀炊飯ボタンや供給される水または洗浄回数などのボタンがコントロールパネル３にさらに設けられ、雑穀炊飯に対するプログラムがコントロールパネル３に設定されれば、本発明による無人自動炊飯装置は多様な種類の雑穀を炊飯するのに用いることができる。   On the other hand, grains such as beans, wheat, millet, rice bran, and miscellaneous grains mixed with rice may be used instead of rice. For this reason, if the control panel 3 is further provided with buttons such as a cereal rice cooking button, water to be supplied or the number of washings, and the program for the cereal rice cooking is set in the control panel 3, the unmanned automatic rice cooking apparatus according to the present invention is various. It can be used to cook various types of millet.
