Let α be a constant value.
次に第２・第３図を用いて、上記構成の炊飯器の動作に
ついて説明する。Next, the operation of the rice cooker having the above configuration will be explained using FIGS. 2 and 3.
第２図は本発明の一実施例の炊飯器の前炊き工程中の加
熱ヒーター２のＯＮ・ＯＦＦする様子を示した図である
。FIG. 2 is a diagram showing how the heater 2 is turned on and off during the pre-cooking process of the rice cooker according to an embodiment of the present invention.
前炊き工程においては、炊飯物を内蔵している１１の温
度を所定時間の間一定の温度に保つことが重要となって
いる。In the pre-cooking process, it is important to maintain the temperature of the rice cooker 11 containing the cooked rice at a constant temperature for a predetermined period of time.
まず、炊飯物の量が少ない場合には、第２図（ａ）に示
されるように炊飯物、即ち鍋１の温度を所定時間の間一
定の温度に保つために、加熱ヒーター２のＯＮ・ＯＦＦ
回数を少ない回数で実施することができる。First, when the amount of rice to be cooked is small, in order to keep the temperature of the rice to be cooked, that is, the pot 1, at a constant temperature for a predetermined period of time, as shown in FIG. 2(a), turn on the heating heater 2. OFF
It can be carried out fewer times.
逆に、炊飯物の量が多い場合には、第２図（ｂ）に示さ
れるように炊飯物、即ち鍋１の温度を所定時間の間一定
の温度に保つために、加熱ヒーター２のＯＮ・ＯＦＦ回
数を多くしなければならない訳である。On the other hand, when the amount of rice to be cooked is large, the heating heater 2 is turned on in order to keep the temperature of the rice to be cooked, that is, the pot 1, at a constant temperature for a predetermined period of time, as shown in FIG. 2(b).・This means that the number of OFF cycles must be increased.
ここで得られた回数がαである。The number of times obtained here is α.
一方、第３図は本発明の一実施例の炊飯器の温度検知手
段４により検知される鍋１の温度上昇の時間経過を示し
た図である。On the other hand, FIG. 3 is a diagram showing the time course of the temperature rise of the pot 1 detected by the temperature detection means 4 of the rice cooker according to an embodiment of the present invention.
まず、炊飯物の量が少ない場合には、第３図の実線に示
されるように炊飯物、即ち鍋１の温度が上昇する。当然
この場合には、あらかじめ決められた第１の所定の温度
Ｔ１から、あらかじめ決められた第２の所定の温度Ｔ２
（＞ＴＩ）までの温度上昇に要する時間ｔはｔｌで示さ
れるように短くなっている。First, when the amount of rice to be cooked is small, the temperature of the rice to be cooked, that is, the pot 1, increases as shown by the solid line in FIG. Naturally, in this case, from the predetermined first predetermined temperature T1 to the predetermined second predetermined temperature T2.
The time t required for the temperature to rise to (>TI) is shorter as shown by tl.
逆に、炊飯物の量が多い場合には、第３図の点線に示さ
れるように炊飯物、即ち鍋１の温度が上昇する。当然こ
の場合には、あらかじめ決められた第１の所定の温度Ｔ
１から、あらかじめ決められた第２の所定の温度Ｔ２（
＞ＴＩ）までの温度上昇に要する時間ｔはｔ２で示され
るように長くなっている。Conversely, when the amount of rice to be cooked is large, the temperature of the rice to be cooked, that is, the pot 1, increases as shown by the dotted line in FIG. Naturally, in this case, the first predetermined temperature T
1 to a predetermined second predetermined temperature T2 (
The time t required for the temperature to rise to >TI) is longer as shown by t2.
このようにして得られた時間がｔである。The time thus obtained is t.
本実施例においては、このようにして得られたαとｔか
ら炊飯量の多少を判定し、沸騰工程における通電率（即
ち火力）を決定している訳である。In this embodiment, the amount of rice to be cooked is determined from α and t obtained in this manner, and the energization rate (i.e., heating power) in the boiling process is determined.
ここで、もし前炊き工程中に停電があった場合には、第
２図からもわかるように加熱ヒーター２のＯＮ・ＯＦＦ
回数が実際あるべき数値より小さく測定されてしまうの
で、交流電源９を検知する停電検知手段１０を設け、前
記αの測定中に交流電源９が停電した場合はαを一定値
とするように構成し不具合の起こらないようにしている
訳である。If there is a power outage during the pre-cooking process, the heating heater 2 can be turned on and off as shown in Figure 2.
Since the number of times is measured to be smaller than the actual value, a power outage detection means 10 is provided to detect the AC power source 9, and if the AC power source 9 experiences a power outage during the measurement of α, α is set to a constant value. This is to prevent any problems from occurring.
また、αは電源電圧が低いときにはヒーター２の加熱出
力が低下するため、同一炊飯量でも増加する傾向を示す
。よって、このαにより電源電圧の低下の有無を判断し
、ｔから得られる炊飯量をαに応じて補正してやれば、
電源電圧の変動を加味した炊飯量判定を行うことができ
る。Further, when the power supply voltage is low, the heating output of the heater 2 decreases, so α tends to increase even if the amount of rice cooked is the same. Therefore, if the presence or absence of a drop in the power supply voltage is determined based on this α, and the amount of cooked rice obtained from t is corrected according to α,
It is possible to determine the amount of cooked rice by taking into account fluctuations in power supply voltage.
また、鍋底に配設した１つの温度検知手段４では、第４
図に示す高温倒の温度Ｔ２は、加熱ヒーター２の熱影響
により検知がばらつくが、αにより炊飯量の判定をある
程度のレベルで行っておけば、ｔがＴ２の大幅な検知ず
れによってずれた場合にも炊飯量の誤判定を防止するこ
とができる。In addition, in one temperature detection means 4 disposed at the bottom of the pot, a fourth
The detection of the high temperature T2 shown in the figure varies due to the thermal influence of the heating heater 2, but if the amount of cooked rice is determined at a certain level using α, if t deviates due to a large detection deviation of T2. It is also possible to prevent misjudgment of the amount of cooked rice.
なお、本実施例では加熱手段として加熱ヒーターを用い
たが、電磁誘導用の加熱コイルを用いてもよく、この加
熱コイルの場合にはデユーティ制御等により加熱制御す
ればよい。Although a heater is used as the heating means in this embodiment, an electromagnetic induction heating coil may also be used, and in the case of this heating coil, heating may be controlled by duty control or the like.
