Description

本発明は重量計測手段により米計量に合致した最適な水計量を得て所望の炊飯が行えるようにした炊飯器に関するものである。   The present invention relates to a rice cooker in which an optimum water metering that matches rice metering is obtained by a weight measuring means so that desired rice cooking can be performed.

従来この種の炊飯器は炊飯ヒーターの上に内鍋を載せて、内鍋と被炊飯物と炊飯ヒーターの全体重量を重量計測手段により計量して、米計量に合致した最適な水計量を得ようとしている(例えば、特許文献1参照)。   Conventionally, this type of rice cooker puts an inner pot on the rice cooker, and weighs the entire weight of the inner pot, the cooked rice, and the rice heater with a weight measuring means, and obtains an optimal water metering that matches rice weighing. (See, for example, Patent Document 1).

図7は、特許文献1に記載された従来の重量センサーを用いた炊飯器を示すものである。図7に示すように、炊飯器本体1は、内鍋2、内容器3、炊飯ヒーター4、重量検出装置5を備えている。重量検出装置5はシャーシー6、歪みゲージを貼付した板バネ7、テーブル8で構成されている。内容器3底面に重量検出装置5のシャーシー6が固定され、
シャーシー6と板バネ7、テーブル8は底面に対して略平行に取り付けられ、テーブル8には炊飯ヒーター4が取り付けられ、内鍋2は炊飯ヒーター4上に載る。
FIG. 7 shows a rice cooker using a conventional weight sensor described in Patent Document 1. As shown in FIG. As shown in FIG. 7, the rice cooker body 1 includes an inner pot 2, an inner container 3, a rice cooker 4, and a weight detection device 5. The weight detection device 5 includes a chassis 6, a leaf spring 7 with a strain gauge attached thereto, and a table 8. The chassis 6 of the weight detection device 5 is fixed to the bottom surface of the inner container 3,
The chassis 6, the leaf spring 7, and the table 8 are attached substantially parallel to the bottom surface, the rice cooking heater 4 is attached to the table 8, and the inner pot 2 is placed on the rice cooking heater 4.

上記構成において内鍋に米や水の被炊飯物を入れ、本体に収納すると、被炊飯物の重量は炊飯ヒーター4、テーブル8を介して板バネ7に伝わり、板バネ7に貼付した歪みゲージの歪み量を電圧等に変換して被炊飯物の重量を検知する。
特許第2832455号公報
In the above configuration, when rice or water to be cooked is put in the inner pan and stored in the main body, the weight of the cooked rice is transmitted to the plate spring 7 through the rice cooker 4 and the table 8 and is attached to the plate spring 7. The weight of the cooked rice is detected by converting the amount of distortion into a voltage or the like.
Japanese Patent No. 2832455

しかしながら、従来例の炊飯器と同様の重量検知手段を、誘導加熱炊飯器に取り付けようとする場合、以下のような問題が生じた。誘導加熱炊飯器においては炊飯時、鍋自体が高温に加熱されることによって鍋の中で水が対流し、その対流による熱伝導で米が加熱される。従って、鍋内の米と水を均一に加熱して炊きムラを生じさせないためには、鍋と誘導加熱コイルとの間の位置関係を最適な状態に固定し、炊飯量に応じて所定の状態、強さの対流を鍋内に起こす必要がある。このため、誘導加熱コイルは3次元的な複雑な形状を有することが多い。一方、誘導加熱コイルを内装する収納部(上部の上枠と下部のコイルベースとから構成される)は、成型性及び量産性を鑑み、通常は樹脂で生産される。鍋は高温になり樹脂の耐熱性はそれほど高くない故に、一般に誘導加熱炊飯器は、鍋が収納部の上端にそのフランジ部などで水平に懸架され、鍋と収納部との間に隙間を有する。従って、従来例の炊飯器と同様の重量検知手段を、誘導加熱炊飯器に取り付けることはできなかった。   However, when trying to attach the same weight detection means as the conventional rice cooker to the induction heating rice cooker, the following problems occurred. In an induction heating rice cooker, when cooking rice, the pan itself is heated to a high temperature to cause convection of water in the pan, and the rice is heated by heat conduction by the convection. Therefore, in order to uniformly heat the rice and water in the pan and not cause uneven cooking, the positional relationship between the pan and the induction heating coil is fixed to an optimal state, and a predetermined state is determined according to the amount of rice cooked. It is necessary to cause convection of strength in the pan. For this reason, the induction heating coil often has a three-dimensional complicated shape. On the other hand, a storage unit (comprising an upper frame and an upper coil base) in which an induction heating coil is built is usually produced from a resin in view of moldability and mass productivity. Since the pot becomes hot and the heat resistance of the resin is not so high, in general, the induction heating rice cooker has a pan that is horizontally suspended at the upper end of the storage part by its flange, etc., and there is a gap between the pot and the storage part . Therefore, the same weight detection means as the conventional rice cooker could not be attached to the induction heating rice cooker.

また、炊きあがったご飯をしゃもじでほぐす時やご飯を茶碗へよそう時、鍋が容易には回転しないようにしなければならないが、従来例の構成は、鍋の底面はテーブル面に載っているので、鍋は回転を規制されていたが、この構成は、鍋と本体の鍋収納部が接触するため採用できないという課題を有していた。   Also, when uncooked rice is cooked or when the rice is put into a bowl, the pan must not be rotated easily, but the conventional configuration is that the bottom of the pan rests on the table surface. The pan was restricted from rotating, but this configuration had a problem that it could not be adopted because the pan and the pan storage part of the main body were in contact.

本発明は前記課題を解決するもので、誘導加熱コイルと鍋との距離を水平方向にも鉛直方向にも一定に保ちつつ、正確に調理物の重量を測定し、測定値に応じて適切に火力制御を行う、電磁誘導加熱を利用した炊飯器を提供することを目的とする。さらに、使用者が炊飯後のご飯をよそう際に、鍋が回転しないようにすることを目的とする。   The present invention solves the above-mentioned problem, accurately measuring the weight of the cooked food while keeping the distance between the induction heating coil and the pan constant in both the horizontal and vertical directions, and appropriately according to the measured value. An object of the present invention is to provide a rice cooker using electromagnetic induction heating that performs thermal power control. Furthermore, it is intended to prevent the pan from rotating when the user tries to cook the cooked rice.

前記従来の課題を解決するために、本発明は、鍋を誘導加熱する誘導加熱手段と、鍋を収納する収納部に設けた重量検出装置を備え、重量検出装置は、重量検知素子を有した起歪体と、その起歪体の一端を固定する固定台と、起歪体の他端に固定されるとともに鍋の外側底部の略中心部に当接する当て筒とを有し、収納部の上端部内面に鍋の外側面に当接する弾性体のシート状の鍋回り止めと、その鍋回り止めの両側に一対の静止部材とを設け、静止部材は上面に段差を有し、鍋回り止めの先端部が両側いずれかの静止部材の段差に当接し収納される炊飯器としたものであり、鍋を重量検出装置に載せた際、当て筒で鍋底部を支持し、本体収納部の内壁面に設けた鍋回り止めを鍋の上端部に接触させて鍋と収納部との距離を確保することにより、水平方向にも鉛直方向にも、誘導加熱手段(IHコイル)との最適距離を保って保持することができ、また鍋が回転しようとすると、鍋回り止めが鍋の周方向に曲がり、抵抗となって、鍋の回転を阻止することができる。 In order to solve the above-described conventional problems, the present invention includes induction heating means for induction heating a pan, and a weight detection device provided in a storage portion for storing the pan, and the weight detection device includes a weight detection element. A strain generating body, a fixing base for fixing one end of the strain generating body, and a contact tube fixed to the other end of the strain generating body and abutting on a substantially central portion of the outer bottom portion of the pan. An elastic sheet-shaped pan stopper that contacts the outer surface of the pan on the inner surface of the upper end and a pair of stationary members on both sides of the pan stopper , the stationary member has a step on the upper surface, When the pan is placed on the weight detection device, the bottom of the pan is supported by a batting cylinder, and the inside of the main body storage unit By securing the distance between the pan and the storage part by bringing the pan detent provided on the wall into contact with the upper end of the pan. In both the horizontal and vertical directions, it can be held at an optimum distance from the induction heating means (IH coil), and when the pan tries to rotate, the pan detent will bend in the circumferential direction of the pan and resist Thus, the pan can be prevented from rotating.

本発明の炊飯器によれば、鍋を重量検出装置に載せて、誘導加熱手段(IHコイル)との最適距離を保って保持することができ、また、使用者が炊飯後のご飯をよそう際に、鍋が回転するのを防ぐことができる。   According to the rice cooker of the present invention, the pan can be placed on the weight detection device and held at an optimum distance from the induction heating means (IH coil), and the user can use the cooked rice. In this case, the pan can be prevented from rotating.

本発明の請求項1に記載の発明は、上面が開口した本体と、前記本体の収納部に着脱自在に収納される鍋と、前記収納部を開閉自在に覆う蓋と、前記鍋を誘導加熱する誘導加熱手段と、前記収納部に設けた重量検出装置を備え、前記重量検出装置は、重量検知素子を有した起歪体と、前記起歪体の一端を固定する固定台と、前記起歪体の他端に固定されるとともに前記鍋の外側底部の略中心部に当接する当て筒とを有し、前記収納部の上端部内面に前記鍋の外側面に当接する弾性体のシート状の鍋回り止めと、前記回り止めの両側に一対の静止部材とを設け、前記静止部材は上面に段差を有し、前記鍋回り止めの先端部が両側いずれかの静止部材の段差に当接し収納されるたことにより、鍋を重量検出装置に載せた際、当て筒で鍋底部を支持し、本体収納部の内壁面に設けた鍋回り止めを鍋の上端部に接触させて鍋と収納部との距離を確保することにより、水平方向にも鉛直方向にも、誘導加熱手段(IHコイル)との最適距離を保って保持することができ、また鍋が回転しようとすると、鍋回り止めが鍋の周方向に曲がり、鍋の外側面と静止部材の間にはさまり、抵抗となって、鍋の回転を阻止することができる。 According to the first aspect of the present invention, there is provided a main body having an open top surface, a pan that is detachably stored in a storage portion of the main body, a lid that covers the storage portion so as to be opened and closed, and induction heating of the pan.

(Embodiment 1)
A first embodiment of the present invention will be described with reference to FIGS. 1 shown in FIG. 1 is the main body of the rice cooker. The main body 10 is provided with a lid 20 that covers the upper surface thereof so as to be freely opened and closed. The housing part 30 of the main body 10 is composed of an upper frame 12 on the upper side and a coil base 13 on the lower side. Reference numeral 11 denotes a pan formed of a magnetic material such as stainless steel or iron. The pan 11 has a flange 11 a protruding to the outside at the upper end opening, and is detachably stored in the storage unit 30 by placing the flange 11 a in a state of being lifted from the upper end of the upper frame 12. The pan 11 has a gap between it and the storage unit 30 when stored. An induction heating coil (induction heating means) 14 for inductively heating the pan 11 is disposed at a portion of the coil base facing the bottom of the pan 11. The induction heating coil 14 is a winding having a center substantially directly below the center of the bottom of the pan 11.

本体10の底部には重量検知素子である歪みセンサー(図示せず)を貼付した起歪体16と起歪体16を固定する固定台17と起歪体16のもう一方の端部に固定し、鍋11の重量を受ける当て筒15からなる重量検出装置30を備えている。当て筒15内には、温度検知手段18が設けられ、コイルバネで付勢されており、鍋11を当て筒15上に載置すると、温度検知手段18が鍋11の底面に当接する。19はシリコンゴムのシート状の小片である鍋回り止めで、その一端が上枠12に固定され、他端は開放端となっている。鍋回り止め19の左右両側には静止部材21が設けられている。   A strain body 16 having a strain sensor (not shown) as a weight detection element attached to the bottom of the main body 10, a fixing base 17 for fixing the strain body 16, and the other end of the strain body 16 are fixed. The weight detection device 30 is provided that includes a batting cylinder 15 that receives the weight of the pan 11. A temperature detecting means 18 is provided in the abutting cylinder 15 and is urged by a coil spring. When the pan 11 is placed on the abutting cylinder 15, the temperature detecting means 18 comes into contact with the bottom surface of the pan 11. Reference numeral 19 denotes a pan stopper which is a silicon rubber sheet-like piece, one end of which is fixed to the upper frame 12 and the other end is an open end. Stationary members 21 are provided on both the left and right sides of the pan detent 19.

本実施の形態においては、鍋回り止め19と静止部材21の組合せで、図2に示されているように、上枠12の上端開口部に均等に3カ所配置されている。鍋回り止め19の一端から他端の長さは3カ所等しくなるように、すなわち、上枠12内壁と鍋11の外側面上部との水平方向の距離が鍋開口部の外周上において等しくなるようにするものである。   In the present embodiment, as shown in FIG. 2, three portions are equally arranged in the upper end opening of the upper frame 12 by the combination of the pan stopper 19 and the stationary member 21. The length from one end of the pan stopper 19 to the other end is equal to three places, that is, the horizontal distance between the inner wall of the upper frame 12 and the upper portion of the outer surface of the pan 11 is equal on the outer periphery of the pan opening. It is to make.

22は制御基板、23は操作基板である。制御基板22にはマイクロコンピューター(図示しない)が搭載されている。マイクロコンピューターはソフトウエアにより、誘導加熱コイル14に交番磁界を発生させるための電流を制御する。第1の実施の形態の炊飯器は、鍋11を誘導加熱し、鍋11内調理物24を加熱調理する。調理物24は、炊飯前の
米と水または炊き上がったご飯等である。25は本炊飯器の操作部、26は表示部、27は水加減を表示するLED、28は確定ボタン、29は炊飯ボタンである。
22 is a control board and 23 is an operation board. A microcomputer (not shown) is mounted on the control board 22. The microcomputer controls the current for generating an alternating magnetic field in the induction heating coil 14 by software. The rice cooker of 1st Embodiment induction-heats the pan 11, and cooks the food 24 in the pan 11 by heating. The cooked food 24 is rice before cooking rice, water, cooked rice, or the like. 25 is an operation part of this rice cooker, 26 is a display part, 27 is LED which displays water addition, 28 is a confirmation button, 29 is a rice cooking button.

上記構成において動作を説明する。蓋20を開けて、本体の電源を入れるとマイクロコンピューターと重量検出装置30に通電され、マイクロコンピューターは予め鍋11の重量が記憶されているので、鍋11の有無を検知する。例えば、空の鍋が入っている状態では本体前面の表示部26には「米計量中」の表示が出る。次に、米計量を確定する確定ボタン28を押すと、表示部26に米の量と水加減中の表示がでる。無洗米の場合は、鍋11に水を入れていくとLED27が左から順次点灯する。米を入れただけの状態では、左端の位置のLEDが点灯する。中央が普通の水加減で中央より右が柔らかめ、中央より左が固めの水加減となる。好みの水加減に設定した後、炊飯ボタンを押すと、炊飯が開始し、設定した硬さのご飯が炊き上がる。米を洗う場合は、確定ボタン28を押した後、鍋11を取り出し、洗米し、再度、鍋11を本体10に設置する。この時、鍋11は当て筒15で鍋底の略中央を支持されると同時に、鍋11の外側面上部は、上枠12に設けられたシリコンゴムシートの鍋回り止め19に接触する。鍋回り止め19に接触することにより、上枠12内壁と鍋11の外側面上部との水平方向の距離が鍋開口部の外周上において等しくなる。従って、鍋11が当て筒15で支持され、鍋回り止め19が鍋11の外側面上部に接触することにより、鍋11と誘導加熱コイル14との距離が一定に保たれるのである。   The operation in the above configuration will be described. When the lid 20 is opened and the main body is turned on, the microcomputer and the weight detection device 30 are energized. Since the weight of the pot 11 is stored in advance, the microcomputer detects the presence or absence of the pot 11. For example, in a state where an empty pan is contained, a display of “measuring rice” appears on the display unit 26 on the front surface of the main body. Next, when the confirmation button 28 for confirming the rice weighing is pressed, the display unit 26 displays the amount of rice and the water being added or subtracted. In the case of washing-free rice, when water is poured into the pan 11, the LEDs 27 are sequentially lit from the left. When rice is just put in, the LED at the leftmost position lights up. The center is normal water, the right is softer than the center, and the left is harder than the center. After setting the desired water level, press the rice cooking button to start cooking and cook the rice with the set hardness. When washing the rice, after pressing the confirmation button 28, the pan 11 is taken out, washed with rice, and the pan 11 is installed in the main body 10 again. At this time, the pan 11 is supported at the substantially center of the bottom of the pan by the batting cylinder 15, and at the same time, the upper portion of the outer surface of the pan 11 comes into contact with the pan detent 19 of the silicon rubber sheet provided on the upper frame 12. By contacting the pan detent 19, the horizontal distance between the inner wall of the upper frame 12 and the upper portion of the outer surface of the pan 11 becomes equal on the outer periphery of the pan opening. Therefore, the pan 11 is supported by the batting cylinder 15 and the pan detent 19 contacts the upper part of the outer surface of the pan 11, whereby the distance between the pan 11 and the induction heating coil 14 is kept constant.

次に、鍋11と米と水の重量が計量される。無洗米と同様に、鍋11に水を注ぎ足していくと、LED27が左から順次点灯するので、好みの水加減に調節して炊飯ボタン29を押して、炊飯を開始する。炊飯終了後、ご飯をほぐしたり茶碗にご飯をよそう時、しゃもじの操作で鍋11が回転しようとすると、鍋11の回転に合わせて上枠上端に設けた鍋回り止め19の開放端側が、鍋11の外側面に沿って曲がり鍋11の上部外側面と静止部材21との間に挟まれることになり、その結果、摩擦が大きくなり鍋11の回転を防止することができるのである。   Next, the pot 11, rice and water are weighed. As in the case of non-washed rice, when water is added to the pan 11, the LEDs 27 are sequentially lit from the left, so that the rice is adjusted to the desired water level and the rice cooking button 29 is pressed to start rice cooking. After cooking the rice, when the pan 11 is about to rotate by the rice paddle operation when the rice is loosened or the rice is served in the bowl, the open end side of the pan detent 19 provided at the upper end of the upper frame in accordance with the rotation of the pan 11 is The bend along the outer surface of the pan 11 is sandwiched between the upper outer surface of the pan 11 and the stationary member 21. As a result, the friction increases and the rotation of the pan 11 can be prevented.

(実施の形態2)
本発明の第2の実施の形態について図3、図4、図5、図6を参照しながら説明する。上枠12の上端には複数個の穴40が設けてあり、穴40にはキャップ41が装着される。キャップ41の下には鍋回り止め19と左右の静止部材21と両端には爪42が設けてあり、爪42と上枠12の穴40に設けたガイド43の下端が係合してキャップ41は上枠12上端に固定される。
(Embodiment 2)
A second embodiment of the present invention will be described with reference to FIGS. 3, 4, 5, and 6. FIG. A plurality of holes 40 are provided at the upper end of the upper frame 12, and a cap 41 is attached to the hole 40. Under the cap 41, the pan stopper 19, the left and right stationary members 21, and claws 42 are provided at both ends, and the lower end of the guide 43 provided in the hole 40 of the upper frame 12 is engaged with the cap 41. Is fixed to the upper end of the upper frame 12.

上記の構成において動作を説明する。実施の形態1と同様に、鍋11を本体10に設置する時、鍋11は当て筒15で鍋底の略中央を支持されると同時に、上枠12に設けられた鍋回り止め19が鍋11の上端外側面部に接触する。   The operation in the above configuration will be described. As in the first embodiment, when the pan 11 is installed on the main body 10, the pan 11 is supported by the batting tube 15 at the substantial center of the pan bottom, and at the same time, the pan detent 19 provided on the upper frame 12 is provided with the pan 11. In contact with the outer surface of the upper end.

そして、鍋回り止め19とその左右両側に設けられる静止部材21をキャップ41と一体化し、上枠12に着脱自在としたことにより、鍋11と上枠12との隙間の距離に合わせて、鍋11と鍋回り止め19及び鍋回り止め19の左右両側に設けた静止部材21との距離を正確に設定することができて、鍋の位置決めを確実におこなうことができる。   Then, the pan stopper 19 and the stationary members 21 provided on both the left and right sides thereof are integrated with the cap 41 so that the pan can be freely attached to and detached from the upper frame 12, so that the pan is adjusted to the distance between the pan 11 and the upper frame 12. 11 and the stationary member 21 provided on the left and right sides of the pan detent 19 and the pan detent 19 can be accurately set, and the pan can be positioned reliably.

図4に示すように、鍋回り止め19の先端部19aを途中部19bより広げた構成とすることにより、鍋回り止め19と鍋11の外側面との接触抵抗力を大きくして、鍋の回転防止が十分に行えるものである。   As shown in FIG. 4, by making the tip 19a of the pan detent 19 wider than the middle portion 19b, the contact resistance force between the pan detent 19 and the outer surface of the pan 11 is increased. The rotation can be sufficiently prevented.

図5に示すように、静止部材21の上面に段差21aを設け、鍋回り止め19の先端部が静止部材21の上面21aの段差に当接する構成としたことにより、鍋回転防止を確実
に行い、鍋回り止め19の引っ張り耐久性を向上させるものである。
As shown in FIG. 5, the step 21 a is provided on the upper surface of the stationary member 21, and the tip of the pan detent 19 is in contact with the step on the upper surface 21 a of the stationary member 21, thereby reliably preventing pan rotation. The pulling durability of the pan detent 19 is improved.

図6に示すように、鍋回り止め19の中間部19bを複数回屈曲させたことにより、シート状弾性体の反発力を下げることにより、鍋計量の精度が向上する。また鍋11が回転しようとすると、鍋回り止め19の先端部19aが抵抗となって、鍋11の回転を確実に防止することができる。   As shown in FIG. 6, the accuracy of pan weighing is improved by lowering the repulsive force of the sheet-like elastic body by bending the intermediate portion 19b of the pan stopper 19 a plurality of times. Moreover, when the pan 11 tries to rotate, the tip 19a of the pan detent 19 becomes a resistance, and the pan 11 can be reliably prevented from rotating.
