し炊飯制御手段５に出力する。FIG. 1 is a block diagram of essential parts of a rice cooker according to an embodiment of the present invention. In the figure, reference numeral 1 is a pot, which contains rice and water to be cooked. A heating heater 2 is a heating means for heating the pot 1. A heater control unit 3 is a heating control unit, which controls ON / OFF of the heater 2. Reference numeral 4 is a temperature detecting means for detecting the temperature of the pot 1. Reference numeral 5 is a rice cooking control means, which receives the output of the temperature detection means 4 as an input and controls the heater control means 3 to pre-cook (rice water absorption step) and boil (boil step).
・ Make rice in the order of Murashi (additional cooking process). Reference numeral 6 is a time measuring means, which takes the output of the temperature detecting means 4 as an input and is required to raise the temperature from a predetermined first predetermined temperature T1 to a predetermined second predetermined temperature T2 (> T1). Measure the time t. Reference numeral 7 is an ON / OFF number detecting means, which measures the number α of times the heater 2 is turned ON / OFF by the heater control means 3 during precooking.

検知し、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。Further, 9 is an AC power supply, 10 is a power failure detection means, and assuming that the AC power supply 9 has a power failure, it detects the power failure of the AC power supply 9, and the AC power supply 9 fails during the measurement of α. Makes α 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 described with reference to FIGS.
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 the 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鍋１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 keep the temperature of the pan 1 containing the cooked rice at a constant temperature for a predetermined 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 cooked rice is small, as shown in FIG. 2 (a), in order to keep the temperature of the cooked rice, that is, the pot 1 at a constant temperature for a predetermined time, the heater 2 is turned on. The number of times of OFF can be reduced.
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 contrary, when the amount of cooked rice is large, as shown in FIG. 2 (b), the heating heater 2 is turned on to keep the temperature of the cooked rice, that is, the pot 1 at a constant temperature for a predetermined time.・ This means that the number of times of OFF 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 pan 1 detected by the temperature detecting means 4 of the rice cooker according to one 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（
＞T1）までの温度上昇に要する時間ｔはt1で示されるよ
うに短くなっている。First, when the amount of cooked rice is small, the temperature of the cooked rice, that is, the pot 1 rises as shown by the solid line in FIG. Of course, in this case, the predetermined first predetermined temperature
From T1, the second predetermined temperature T2 (
The time t required for the temperature rise up to> T1) is shortened as indicated by t1.
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T1
から、あらかじめ決められた第２の所定の温度T2（ ＞
T1）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 cooked rice is large, the temperature of the cooked rice, that is, the pot 1 rises as shown by the dotted line in FIG. Of course, in this case, the predetermined first predetermined temperature T1
From the second predetermined temperature T2 (>
The time t required for the temperature rise up to T1) is long 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 the present embodiment, the amount of cooked rice is determined from α and t thus obtained, and the energization rate (that is, the heating power) in the boiling step 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。Here, if there is a power outage during the pre-cooking process, the number of times the heater 2 is turned on and off will be measured smaller than it should be, as can be seen from FIG. 2,
A power failure detecting means 10 for detecting the AC power supply 9 is provided, and when the AC power supply 9 fails during the measurement of α, α is set to a constant value so that no trouble occurs.
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, α has a tendency that the heating output of the heater 2 decreases when the power supply voltage is low, and therefore increases even with the same amount of cooked rice. Therefore, by determining whether or not the power supply voltage is decreased by this α and correcting the rice cooking amount obtained from t according to α, it is possible to perform the rice cooking amount determination in consideration of the fluctuation of the power source voltage.
また、鍋底に配設した１つの温度検知手段４では、第４
図に示す高温側の温度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。Further, in the one temperature detecting means 4 arranged on the bottom of the pan,
The temperature T 2 on the high temperature side shown in the figure varies in detection due to the heat effect of the heater 2. However, if the amount of cooked rice is judged to some extent by α, t will shift due to a large detection deviation of T 2. Even when the rice is cooked, the misjudgment of the amount of cooked rice can be prevented.
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ューティ制御等により加熱制御す
ればよい。Although the heater is used as the heating means in this embodiment, a heating coil for electromagnetic induction may be used, and in the case of this heating coil, heating control may be performed by duty control or the like.

することができるわけである。Effects of the Invention As described above, the present invention is a pot for containing rice,
Heating means for heating this pot and turning this heating means on and off
The heating control means for controlling, the temperature detecting means for detecting the temperature of the pot, and the output of this temperature detecting means are used as inputs to control the heater controlling means to precook (rice water absorption step).
The first predetermined temperature T1 determined in advance by inputting the output of the rice-cooking control means for cooking rice in the order of boil-up (boiling step) and Murashi (up-cooking step)
From the second predetermined temperature T2 (>
T1) a time measuring means for measuring the time t required to increase the temperature, and the heating control means by the heating control means during precooking.
ON / OFF frequency detection means for measuring the number of times ON / OFF, α
Since the time t and the ON / OFF frequency α determine the energization ratio to the heating means and output it to the rice cooking control means, the temperature is detected by one sensor. However, even if there is a variation in t related to the amount of cooked rice due to variations in the temperature measurement, the energization rate is determined by taking into account the value of α in addition to t, and as a result, the heating power setting during boiling also varies. Therefore, it is possible to provide a rice cooker capable of accurately determining the amount of cooked rice even with one sensor.

Since it is also configured, it is possible to provide a rice cooker that does not cause any worry even if there is a power outage during rice cooking.
