Description

この発明は、電子レンジで米、または、無洗米を炊飯する際に、容器に、熱容量が大きい、熱伝導性が低い、遠赤外線を放射する、といった特性をもつ、土鍋を使用することによって、単純な出力調整で自動炊飯を行うことのできるプログラムを組み込んで、自動でご飯を炊くことができるようにした、自動炊飯モード付電子レンジに関するものである。 The present invention, in a microwave oven, rice, or, when cooking the pre-washed rice, in a container, having a large thermal capacity, low thermal conductivity, radiates far infrared, having characteristics such as, by using a pot The present invention relates to a microwave oven with an automatic rice cooking mode that incorporates a program that can perform automatic rice cooking with simple output adjustment so that rice can be cooked automatically.

単身者やお年寄世帯、働く母親の増加等、社会構造の変化で炊飯に求められているのは「少量・簡単・安全」である。少量のご飯をおいしく炊く事は、炊きムラが生じやすく、ガスや電気の炊飯器でも難しい。   “Small amount, easy, safe” is required for cooking rice due to changes in social structure such as singles, elderly households, and increasing working mothers. Cooking a small amount of rice deliciously tends to cause uneven cooking, and even with a gas or electric rice cooker.

電子レンジでおいしく炊飯するためには、水や米の量により異なる温度や湿度の変化をセンサーで測定して出力を微妙に調整する必要があり、プログラムが複雑になり商品化が難しかった。(特許文献1)(特許文献2)   In order to cook deliciously in a microwave oven, it was necessary to measure changes in temperature and humidity that differ depending on the amount of water and rice with a sensor and finely adjust the output, making the program complicated and difficult to commercialize. (Patent Document 1) (Patent Document 2)

少量の暖かいご飯が火を使わないで短時間で出来るという点で、電子レンジで温めるパックご飯は便利で、需要が高まっているが、プラスチックゴミの増加が心配される。また、陶器製で一膳分の炊飯を電子レンジでする商品は、茶碗型の形状により熱対流が起こりにくく炊きむらの生ずる難点があり、また、出力:弱のみで炊飯するため多い量を炊飯するのは難しい。

Packed rice cooked in a microwave oven is convenient and demand is increasing because a small amount of warm rice can be produced in a short time without using fire, but there is a concern about the increase in plastic garbage. In addition, products made of pottery made with a microwave oven for cooking a portion of rice have a disadvantage that heat convection is difficult to occur due to the shape of the tea bowl, and there is a difficulty in cooking unevenness. Difficult to do.
JP 4-270824 JP 5-223256 Special table 2004-507709

従来、電子レンジで米、または、無洗米をおいしく炊飯するためには、米や水の量により異なる温度や湿度の変化をセンサーで測定して出力を微妙に調整する必要があり、プログラムが複雑になり商品化が難しかった。 Conventionally, a microwave oven, rice, or to delicious cooking the pre-washed rice, it is necessary to finely adjust the to output measure changes in different temperatures and humidity by the amount of rice and water by the sensor, the program It became complicated and difficult to commercialize.

本発明は、電子レンジで米、または、無洗米を炊飯する場合において、熱容量が大きい、熱伝導性が低い、遠赤外線を放射する、といった特性をもつ土鍋を容器に使用することと電子レンジの出力を加熱開始から10分〜20分の間に沸騰するよう調整することにより、おいしいご飯を炊き上げることができるようにしたプログラムを組み込んだ、自動炊飯モード付電子レンジに関するものである。 The present invention, in a microwave oven, rice, or, in the case of cooking the pre-washed rice, having a large thermal capacity, low thermal conductivity, and using radiating far infrared rays, the pot having such characteristics to the container, electronic It relates to a microwave oven with an automatic rice cooking mode that incorporates a program that can cook delicious rice by adjusting the output of the range to boil between 10 and 20 minutes from the start of heating. .

この電子レンジによれば、決められた量の洗った(無洗米ならそのまま)米と水を土鍋に入れて、電子レンジのスイッチを入れれば、加熱出力は自動制御され、短時間で、芯も、炊きムラも無いおいしいご飯が炊き上がる。   According to this microwave oven, if you put a fixed amount of washed (unwashed rice as it is) rice and water in a clay pot, and turn on the microwave oven, the heating output is automatically controlled, and the core is also fast. Delicious rice with no cooking unevenness is cooked.

米の体積に対する水の量は1.3倍、無洗米の場合は普通米を洗っている間に吸水される分として1割増しの1.4倍を標準とする   The amount of water relative to the volume of rice is 1.3 times, and in the case of non-washed rice, the amount of water absorbed while washing ordinary rice is increased by 10%, which is 1.4 times the standard.

土鍋の形状は、沸騰時に蓋の穴からの噴出物の流出を防ぐために蓋が中に納まるものが望ましい。また、熱対流を速やかにするために底は平らな面があり丸みを帯びたものが良い。 The shape of the earthenware pot is preferably such that the lid fits inside in order to prevent the ejected material from flowing out of the hole in the lid when boiling. Moreover, in order to make thermal convection quick, the bottom should have a flat surface and be rounded.

浸漬時間は5分程度で加熱を開始することができる。   Heating can be started with an immersion time of about 5 minutes.

間配分は、米と水の量、気温や水の温度、土鍋の大きさによって変わる。 Time between allocation, rice and the amount of water, temperature and water temperature varies depending on the size of the pot.

加熱の第1段階における出力:弱での加熱で、電子レンジのマイクロ波と水温上昇により浸漬は促進されるが、土鍋の特性である、熱容量が大きく熱伝導性が低い事により水温上昇は緩慢になり、米粒内部まで水分を行き渡らせる事ができる。芯の無いご飯を炊くためには、十分な浸漬のほかに、加熱時間が早過ぎないことも大切である。短時間で高温になると、米粒表面の糊化が先に進み、内部の糊化を妨げることになる。よく浸漬された米でも芯のあるご飯ができるのは、このケースであり、少ない量の米をおいしく炊くのが難しいのは、この点にある。   Output in the first stage of heating: Heating at a low level promotes soaking by microwave microwave and water temperature rise, but the rise in water temperature is slow due to the characteristics of the earthenware pot, large heat capacity and low thermal conductivity It is possible to spread moisture to the inside of the rice grain. In addition to sufficient soaking, it is important that the heating time is not too early for cooking rice without a core. When the temperature rises in a short time, the gelatinization of the surface of the rice grains proceeds and the internal gelatinization is hindered. This is the case where well-soaked rice can produce core rice, and this is why it is difficult to cook small amounts of rice deliciously.

加熱の第2段階の出力:強は、沸騰までの時間を適度に早めるためのものである。第1段階の出力:弱と第2段階の出力:強で、「始めちょろちょろ、中ぱっぱ」の、炊飯に理想的な加熱となる。   The output of the second stage of heating: Strong is for moderately increasing the time to boiling. The output of the first stage: weak and the output of the second stage: strong, which is an ideal heating for cooking rice at the beginning, a little bit.

第3段階の出力:弱で沸騰するように調整する。出力:強で沸騰させると沸騰が激しくなるからである。加熱開始から沸騰するまでの時間を10〜20分とするよう出力制御する。Third stage output: Adjust to weak and boil. Output: It is because boiling is intense when boiling is strong. The output is controlled so that the time from the start of heating to boiling is 10 to 20 minutes.

蒸らしの間も、温められた土鍋から遠赤外線が放射される事と、熱容量が大きい事とにより、じっくりと芯まで蒸らされて、ふっくらとしたご飯に炊き上がる。     During steaming, far infrared rays are emitted from the warmed earthenware pot and the heat capacity is large, so it is steamed to the core and cooked into plump rice.

温度センサーを利用して、気温の低い場合は、出力:強での加熱時間を延ばす、加熱前の浸漬段階で水温を上げる。If the temperature is low by using a temperature sensor, increase the water temperature in the soaking stage before heating, extending the heating time at output: strong.

気温25℃では、6号土鍋(0.8リットル・1〜2人用)を使用し、米200ccを200W→500W→200Wを2分→5分→10分で制御して炊飯し、茶碗二膳分、およそ600ccの御飯が、おいしく炊けた気温が低い場合は、500Wでの加熱時間を延ばしておいしく炊けた。 In the temperature 25 ℃, using a No. 6 pot (for 0.8 liters, 1 to 2 people), rice 200cc, and rice to control the 200W → 500W → 200W at 2 minutes → 5 minutes → 10 minutes, bowl For two meals, about 600cc of rice was cooked deliciously . When the temperature was low, we extended the heating time at 500W and cooked deliciously.

同様に、気温25℃では、深型6号土鍋(1.6リットル)、7号土鍋(1.0リットル・2〜3人用)を使用し、実施例1の米200ccの他に、米300ccが200W→500W→200Wを2分→8分→7分で制御して茶碗三膳分がおいしく炊けた。米400ccの場合、200W→500W→200Wを2分→11分→4分の制御で、茶碗四膳分がおいしく炊けた。米の量は±20cc程度まで同じ時間制御で炊く事ができた。従って、米180cc〜420ccまでなら、「加熱」の第2段階は500Wで炊飯可能である。米450cc以上を炊く場合は第3段階の出力:強を600W以上に設定する

Figure 0004143936
Similarly, at a temperature of 25 ° C, deep type No. 6 earthenware pan (1.6 liters) and No. 7 earthenware pan (1.0 liters for 2 to 3 people) are used. 300cc was controlled from 200W → 500W → 200W in 2 minutes → 8 minutes → 7 minutes. In the case of 400cc rice, 200W → 500W → 200W was controlled from 2 minutes → 11 minutes → 4 minutes. The amount of rice could be cooked under the same time control to about ± 20cc. Therefore, if it is from 180cc to 420cc of rice, the second stage of "heating" can be cooked at 500W. When cooking more than 450cc of rice, set the output of the third stage: strength to 600W or more .

Figure 0004143936

一人暮し用の電子レンジに、200cc用のプログラムを付ければ、茶碗二膳分が簡単に炊ける。二膳目は土鍋のまま再加熱でき、少ないご飯を保温する必要はなくなる。狭い台所で炊飯器のスペースが要らなくなる。   If you attach a 200cc program to a single-use microwave, you can easily cook a bowl of teacups. The second pot can be reheated in a clay pot, eliminating the need to keep a small amount of rice warm. Eliminates the need for a rice cooker space in a small kitchen.

一般の家庭用の電子レンジに、200cc、300cc、400cc用のプログラムを付けても、それ程コストはかからない。お年寄世帯や、働く母親を待っている子供でも、火を使わないから安全にご飯を炊く事が出来る。   Adding a 200cc, 300cc, or 400cc program to a general household microwave oven does not cost much. Even elderly households and children waiting for working mothers can cook rice safely without using fire.

回分に分包された米、または無洗米や、それに対応した水の計量カップがあれば、細かい字や目盛りが読みにくいお年寄や、数字が読めない子供にとってもさらに便利である一回分にした米に対応した量の「合わせ酢」の小さなパックがあれば、鮨飯も手軽に作ることもできる。土鍋に、米に対する水の量を提示する線をつけたものも、水の計量の手間を省くのに役立つ。 A single- packed or unwashed rice and a corresponding measuring cup for water are even more convenient for elderly people who have difficulty reading fine characters and scales, and for children who cannot read numbers . If you have a small pack of “matched vinegar” that corresponds to the amount of rice in a single batch, you can easily make rice. A clay pot with a line that shows the amount of water relative to the rice also helps to save water.
