Description

本発明は、重量センサで米の重量を検出し、この重量を基に加熱制御する炊飯器に関するものである。   The present invention relates to a rice cooker that detects the weight of rice with a weight sensor and controls heating based on the weight.

従来、電気炊飯器で炊飯する場合、付属の計量カップで米の分量を計り、米を研いでから炊飯器の米を入れる内釜に表示されている水位目盛りに従い、水加減を行なってから炊飯するための加熱工程に入り炊飯を行なっていた。   Conventionally, when cooking with an electric rice cooker, measure the amount of rice with the attached measuring cup, sharpen the rice and then add and subtract water according to the water level scale displayed on the inner pot where the rice in the rice cooker is placed. I went into the heating process to do cooking rice.

しかし、軽量カップで米の分量を計ったり、米の分量に見合った水加減を、米を入れる内釜に表示されている水位目盛りに合わせることは、目視で行なうため正確性にかけ、真のおいしい炊飯がなされないことがあり問題であった。   However, measuring the amount of rice with a lightweight cup, and adjusting the water level corresponding to the amount of rice to the water level scale displayed on the inner pot where the rice is put, is done by visual inspection, so it is true and delicious. There was a problem that rice was not cooked.

また、炊飯量は前炊き工程での温度の立ち上がり特性で検出しているため、前炊き工程において炊飯に最適とされる特定の炊飯曲線に合わせた加熱制御は難しい問題を有していた。   Moreover, since the amount of rice cooking is detected by the temperature rise characteristic in the pre-cooking process, heating control in accordance with a specific rice cooking curve that is optimal for cooking in the pre-cooking process has a difficult problem.

この問題を解決するため特開平5−261018号公報で開示されているように重量センサを炊飯器の内釜のフランジ部に設け、図8に示す炊飯曲線における前炊き工程の前または前炊き工程の開始と同時に炊飯量を検知し、炊飯量に応じて加熱出力を制御することにより、前炊き工程から炊飯量に関係なく、常に特定の炊飯曲線に沿って加熱制御するものがあった。   In order to solve this problem, as disclosed in Japanese Patent Laid-Open No. 5-261018, a weight sensor is provided in the flange portion of the inner pot of the rice cooker, and before the pre-cooking process or the pre-cooking process in the rice cooking curve shown in FIG. At the same time, the amount of rice cooked was detected, and the heating output was controlled according to the amount of rice cooked, so that there was something that always controlled the heating along a specific rice cooking curve from the pre-cooking process regardless of the amount of rice cooking.

特開平5−261018号公報Japanese Patent Laid-Open No. 5-261018

近年、電気炊飯器における熱源はシーズヒータ方式からIH方式に変わってきている。シーズヒータ方式の場合はシーズヒータからのふく射熱や伝導熱が主であるため米を入れる内釜の材質は熱伝導が良いアルミニュームが中心であった。   In recent years, the heat source in an electric rice cooker has changed from the sheathed heater method to the IH method. In the case of the sheathed heater method, radiant heat and conduction heat from the sheathed heater are mainly used, so the material of the inner pot in which rice is put was mainly aluminum with good heat conduction.

一方、IH方式は加熱コイルから発生した磁力線により内釜の内部でうず電流が発生し、内釜の電気抵抗によって内釜自体が発熱する。従って効率よく発熱させるためには電気抵抗分が多い鉄系のものが良いため内釜は鉄系の材質で構成されている。   On the other hand, in the IH system, an eddy current is generated inside the inner hook by the magnetic lines generated from the heating coil, and the inner hook itself generates heat due to the electric resistance of the inner hook. Therefore, in order to generate heat efficiently, an iron-based one having a large electrical resistance is preferable, so the inner pot is made of an iron-based material.

このため、IH方式は内釜自身が発熱源となるためシーズヒータ方式より早く、効率よく、強い火力で加熱できるため、おいしい炊飯ができ炊飯器の熱源の主流となっている。   For this reason, in the IH method, since the inner pot itself becomes a heat source, it can be heated more quickly and efficiently with a strong heating power than the sheathed heater method, so that delicious rice can be cooked and becomes the mainstream heat source of rice cookers.

しかし、上述したようにIH方式の内釜は鉄系の材質が主であるため重量が重くなり内釜に入れた米の重量比は小さくなり、米だけの重量を算出するときは不安定要因をできるだけ排除する必要があった。   However, as mentioned above, the IH type inner pot is mainly made of iron-based material, so the weight becomes heavier and the weight ratio of rice in the inner pot becomes smaller. It was necessary to eliminate as much as possible.

従って、内釜の重量が検出できる重量センサは正確な米の重量が選出できる有効な手段である。   Therefore, a weight sensor capable of detecting the weight of the inner pot is an effective means for selecting an accurate rice weight.

このような状況のなか、特許文献1におけるものは重量センサを使用することにより米の重量を検出しこの重量を基に炊飯を行なっている。   In such a situation, the thing in patent document 1 detects the weight of rice by using a weight sensor, and cooks rice based on this weight.

しかし、図7に示すように内釜30のフランジ部30aの一箇所で重量センサ31を押圧するレバー31aと連結する連結棒31bと当接する構造であるため、この重量センサ31と連結する連結棒31b以外のところで内釜30のフランジ30b部が本体を構成する本体上枠32と接触することにより荷重バランスが変化し、内釜30に収容した米33の重量を正確に測定しにくいという課題があった。   However, as shown in FIG. 7, the connecting rod 31 b is connected to the lever 31 a that presses the weight sensor 31 at one location of the flange portion 30 a of the inner hook 30. The load balance changes when the flange 30b portion of the inner hook 30 comes into contact with the main body upper frame 32 constituting the main body at a place other than 31b, and it is difficult to accurately measure the weight of the rice 33 accommodated in the inner hook 30. there were.

本発明は上記課題を解決するために、米を入れる内釜と、この内釜の重量を計量する重量センサと、この重量センサからの情報を基に前記内釜内の前記米の重量を算出したり、炊飯時に温度検出手段からの温度情報を基に内釜の温度を制御したりする制御部と、内釜を加熱する加熱手段を具備した炊飯器において、前記内釜のフランジ部で重量センサと連結している支持部材を押圧することにより内釜の重量を検出する重量センサを少なくとも3個設けたものである。   In order to solve the above-mentioned problems, the present invention calculates the weight of the rice in the inner pot based on information from the inner pot for storing rice, a weight sensor for measuring the weight of the inner pot, and the weight sensor. Or a rice cooker equipped with a controller for controlling the temperature of the inner pot based on temperature information from the temperature detecting means during rice cooking, and a heating means for heating the inner pot. At least three weight sensors for detecting the weight of the inner hook by pressing a supporting member connected to the sensor are provided.

また、支持部材が貫通する本体上枠の穴に浸入する水や塵埃などを防ぐ漏水防止手段を設けたものである。   Further, water leakage preventing means for preventing water, dust and the like entering the hole of the upper frame of the main body through which the support member penetrates is provided.

以上本発明によれば、米を入れる内釜と、この内釜の重量を計量する重量センサと、この重量センサからの情報を基に前記内釜内の前記米の重量を算出したり、炊飯時に温度検出手段からの温度情報を基に内釜の温度を制御したりする制御部と、内釜を加熱する加熱手段を具備した炊飯器において、前記内釜のフランジ部で重量センサと連結している支持部材を押圧することにより内釜の重量を検出する重量センサを少なくとも3個設け、これらからの重量情報を制御部で合計することにより予め設定された演算で内釜に収容された米の重量が正確に検出することができ、米の量に応じて水量設定が正確にできることにより、内釜に収容された米の炊飯量によって加熱制御を特定できるので前炊き工程から最適とされる特定の炊飯曲線に沿って加熱することができ、常においしいご飯が炊ける。   As described above, according to the present invention, an inner pot for putting rice, a weight sensor for measuring the weight of the inner pot, the weight of the rice in the inner pot based on information from the weight sensor, In a rice cooker equipped with a controller for controlling the temperature of the inner pot based on temperature information from the temperature detecting means and a heating means for heating the inner pot, the flange part of the inner pot is connected to the weight sensor. At least three weight sensors that detect the weight of the inner hook by pressing the supporting member are provided, and the weight information from these sensors is summed up by the control unit so that the rice stored in the inner hook is calculated in advance. The weight of the rice can be detected accurately, and the amount of water can be accurately set according to the amount of rice, so the heating control can be specified by the amount of rice cooked in the inner pot, so it is optimal from the pre-cooking process Along a specific cooking curve It can be heated, always delicious rice cook.

また、支持部材が貫通する本体上枠の穴に浸入する水や塵埃などを防ぐ漏水防止手段を設けたことにより、本体上枠に水がこぼれても重量センサを構成する部品や基板を濡らすことを防ぐ効果がある。   In addition, by providing water leakage prevention means that prevents water and dust from entering the holes in the upper frame of the main body through which the support member penetrates, even if water spills into the upper frame of the main body, the parts and the board that make up the weight sensor are wetted. There is an effect to prevent.

Reference numeral 11 denotes an operation unit for displaying the hour / minute key 11a for setting the time, the menu key 11b for selecting a menu such as porridge or miscellaneous food, the time set by the hour / minute key 11a, the weight of the rice 3a measured by the weight sensor 7, and the like. A display unit 11c and a start key 11d for the user to instruct the control unit 8 to start cooking rice are arranged.

このように構成された炊飯器の作用について説明する。   The effect | action of the rice cooker comprised in this way is demonstrated.

使用者が炊飯するとき内釜2に必要に応じた量の米3aを内釜2に入れ、内容器1d内にセットする。すると本体上枠1aの穴1a1を貫通して本体上枠1aの上面より出っ張るように設けられた支持部材7aは内釜2のフランジ部2aにより押し下げられ下方に移動し支持部材7aの下端に設けられた重量センサ7に重量情報を伝達する。   When the user cooks rice, an amount of rice 3a as needed is put in the inner pot 2 and set in the inner container 1d. Then, the support member 7a provided so as to penetrate the hole 1a1 of the main body upper frame 1a and protrude from the upper surface of the main body upper frame 1a is pushed down by the flange portion 2a of the inner hook 2 and moved downward to be provided at the lower end of the support member 7a. The weight information is transmitted to the weight sensor 7 provided.

そして、それぞれの重量センサ7は内釜の重量情報を制御部8に送りここで合計することにより内釜2の重量が算出される。   Then, each weight sensor 7 sends the weight information of the inner hook to the control unit 8 and totals the weight information to calculate the weight of the inner hook 2.

さらに、制御部8では予め設定された演算により米3aの重量を算出する。このため内釜2内で米がかたよって置かれた場合でも、3個の重量センサ7で内釜2の重量が的確に検出ができ、内釜2の重量情報を安定的に得ることができる。   Further, the control unit 8 calculates the weight of the rice 3a by a preset calculation. For this reason, even when the rice is placed inside the inner hook 2, the weight of the inner hook 2 can be accurately detected by the three weight sensors 7, and the weight information of the inner hook 2 can be stably obtained. .

制御部8で算出された内釜2の米3aの重量は操作部11の表示部11cに表示するとともに制御部8に記憶される。   The weight of the rice 3 a of the inner pot 2 calculated by the control unit 8 is displayed on the display unit 11 c of the operation unit 11 and stored in the control unit 8.

次に、内釜2を内容器1dから取り出し米3aを水で研ぐ。研ぎ終わったら水を切り、再び内釜2を内容器1dにセットする。そして、内釜2に表示されている重量と水量の関係から先ほど計量し記録した米3aの重量に対応した水3bを加える。   Next, the inner pot 2 is taken out from the inner container 1d and the rice 3a is sharpened with water. When the grinding is finished, drain the water and set the inner pot 2 in the inner container 1d again. Then, water 3b corresponding to the weight of the rice 3a measured and recorded from the relationship between the weight displayed on the inner pot 2 and the amount of water is added.

次に、蓋4を閉め炊飯のスタートキー11dを押して、炊飯を開始する。炊飯開始より制御部8では記憶された米3aの重量に合わせて、図5に示すようなおいしい炊飯になるよう予め設定した炊飯曲線に見合った加熱制御を行い炊飯する。   Next, the lid 4 is closed and the rice cooking start key 11d is pressed to start rice cooking. From the start of rice cooking, the control unit 8 cooks rice by performing heating control corresponding to a preset rice cooking curve so as to obtain a delicious rice cooking as shown in FIG. 5 in accordance with the stored weight of the rice 3a.

尚、本発明では重量センサ7を3箇所に設定したが、長方形で、かつ大型の内釜2(図示せず)の場合、重量センサ7は4箇所設けた方が安定して重量が検出できる場合もあるので重量センサ7の数は3箇所に限定するものではない。   In the present invention, the weight sensor 7 is set at three locations. However, in the case of a rectangular and large inner hook 2 (not shown), the weight sensor 7 can detect the weight more stably when provided at four locations. In some cases, the number of weight sensors 7 is not limited to three.

次に、支持部材7aが貫通する本体上枠1aの穴1a1から重量センサ7に浸入する水を防ぐ漏水防止手段12について説明する。   Next, the water leakage preventing means 12 for preventing water entering the weight sensor 7 from the hole 1a1 of the main body upper frame 1a through which the support member 7a passes will be described.

炊飯するために内釜2に米3a、水3bをいれて内容器1dにセットするとき内釜2の外側に付着していた水滴が本体上枠1aに落下したり、あるいは使用者が誤って内釜2内の水を本体上枠1aにこぼすことはよくあることである。   When rice 3a and water 3b are put in the inner pot 2 and set in the inner container 1d to cook rice, water drops adhering to the outside of the inner pot 2 fall on the main body upper frame 1a, or the user mistakenly It is common for water in the inner pot 2 to spill into the main body upper frame 1a.

このとき、本体上枠1aにある穴1a1に水がこぼれた場合、水は支持部材7aを伝わって重量センサ7に流入する。重量センサ7に達した水は重量センサ7を構成する電気部品(図示せず)や基板(図示せず)を濡らすことにより正常に動作できなくなることも考えられる。   At this time, if water spills into the hole 1a1 in the main body upper frame 1a, the water flows through the support member 7a and flows into the weight sensor 7. It is also conceivable that the water that has reached the weight sensor 7 becomes unable to operate normally by wetting an electrical component (not shown) or a substrate (not shown) that constitutes the weight sensor 7.

このような事態を防ぐのが漏水防止手段12である。この漏水防止手段12は図6(a)に示すように柔軟性があり支持部材7aの可動に影響がないシリコン性のシール剤による漏水防止手段12を塗布するとか、図6(b)に示しようにシリコンゴムのような耐熱性ゴムで成型したパッキンによる漏水防止手段12で支持部材7aを覆うことも考えられる。   It is the water leakage prevention means 12 that prevents such a situation. As shown in FIG. 6 (a), the water leakage prevention means 12 is flexible and may be applied with a water leakage prevention means 12 made of a silicone sealant that does not affect the movement of the support member 7a. Thus, it is also conceivable to cover the support member 7a with the water leakage prevention means 12 by packing molded with heat-resistant rubber such as silicon rubber.

このように内釜2のフランジ部2aが支持部材7aを押圧することにより、支持部材7aと連動した3個の重量センサ7で算出した内釜2の重量情報を制御部8に送りここで米3aの重量が正確に検出できるため、この重量を基準においしい炊飯が可能となる。   Thus, when the flange portion 2a of the inner hook 2 presses the support member 7a, the weight information of the inner hook 2 calculated by the three weight sensors 7 interlocked with the support member 7a is sent to the control unit 8, where Since the weight of 3a can be detected accurately, delicious rice cooking can be performed based on this weight.
