［産業上の利用分野コ
本発明は炊飯器による炊飯において、米飯表面の乾燥を
防止し、蓋部品の過熱による変形を防止した加熱方法に
関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a heating method for cooking rice using a rice cooker, which prevents the surface of the cooked rice from drying and prevents the lid part from being deformed due to overheating.
［従来の技術］
電力を利用して加熱炊飯する炊飯器は、今や全国的に普
及し各家庭の炊事場の必須器具となっている。それだけ
にその技術開発にかける各メーカの熱意は素晴らしいも
のがあり、文字通り日進月歩の様相を呈している。[Prior Art] Rice cookers that heat and cook rice using electricity are now popular throughout the country and have become essential appliances in the kitchens of every household. Therefore, the enthusiasm of each manufacturer for developing this technology is amazing, and progress is literally being made every day.
開発の最大の狙いは、米をいかに美味な飯に炊き上げる

に強化されている。The main aim of development is how to cook rice into delicious rice, and to this end, constant development efforts are being made in every detail. Particularly recently, in order to improve the taste of cooked rice, it has become effective to heat the inner pot in which the rice is stored not only from the bottom but also from the top.In the past, this method was mainly used to keep the rice warm. The output of the lid heater has been strengthened, and a rice cooking method has been adopted in which the lid heater is used from above to heat rice during cooking. Therefore, the output of the lid heater has recently been increased from 10 watts to 60 to 80 watts.

なくなると、飯米の温度は図にみるように急上昇する。FIG. 3 is a heating curve when cooked rice is cooked using the rice cooker described above, and shows the change in the temperature of the cooked rice over time. First, a predetermined amount of rice and water are stored in the inner pot 3, and when the switch is turned on at the 0 point, the bottom heater 4 and the lid heater 5 are turned on, heating the rice and water from the bottom and top. The temperature of the rice and water in the inner pot 3 rises as the rice heats up, and when it reaches point P, it begins to boil. During boiling, the temperature of the cooked rice remains at the boiling point of 100°C, but as the cooking progresses and no more water evaporates at point Q, the temperature of the cooked rice rises rapidly as shown in the figure.

状態に入るのである。A thermistor disposed in contact with the bottom of the inner pot detects this rising temperature at the R point of 130° C., and the output of the bottom heater 4 is reduced to almost zero, entering into an uneven state. When a predetermined period of time has elapsed during the heating process, the body heater 6 is activated to enter a heat retention state.
上記炊飯において、スイッチＯＮから沸騰までの期間を

過程と称する。爾後むらし過程及び保温過程である。In the above-mentioned rice cooking, the period from turning on the switch to boiling is the temperature rising period, and the period during boiling is called the boiling period, and both are collectively referred to as the rice cooking process. These are the unevenness process and the heat retention process.

をきたす恐れがあり、かねてより問題となっている。[Problems to be Solved by the Invention] By the way, in the above-mentioned rice cooking process, the lid heater is operated together with the bottom heater to heat the inner pot from the bottom and top. As a result, the surface of the cooked rice may become overheated and dry. Additionally, the interior of the lid may become overheated due to the lid heater, resulting in deformation of the lid parts. If the output of the lid heater is lowered using the heating amount control means to avoid this, there is a risk that the heating will be insufficient and the rice cooking will be hindered, which has been a problem for some time.
本発明は従来の炊飯器の上記問題点を解消するためにな
されたもので、米飯表面を乾燥させず、蓋の部品を変形

させるようにする。Means for Solving Problem C] In order to achieve the above object, the rice cooking method according to the present invention maximizes the output of the lid heater during the period when the temperature of cooked rice is rising, and reduces the output of the lid heater during the boiling period. Try to lower it.
上記のように沸騰期間においては蓋ヒータの出力を低減
させたので、米飯の表面が乾燥することもなく、蓋の部
品が過熱することもない。As mentioned above, since the output of the lid heater is reduced during the boiling period, the surface of the cooked rice does not dry out, and the parts of the lid do not overheat.

せる。[Embodiment of the Invention] FIG. 1 shows a temperature curve of cooked rice and an output of a lid heater according to an embodiment of the invention. When cooking rice, as shown in the figure, the output of the lid heater is 100% during the rice temperature rising period, but the thermistor attached to the bottom of the inner pot 3 of the rice cooker detects boiling inside the inner pot. Then, the output of the lid heater is reduced to a predetermined output using the heating amount control means.
