、爾後保温過程が持続するのである。Figure 3 is a diagram showing the heating curve for rice cooking.When cooking rice, first put a predetermined amount of rice and water in the inner pot 3, and turn on the switch at the 0 point, the bottom heater 4 turns on. Heat the inner pot 3 from the bottom. Inner pot 3 depending on heating
The temperature of the rice and water inside rises and when it reaches point P, it begins to boil. During boiling, the temperature of the cooked rice maintains the boiling point of 100°C, but as the cooking progresses and no more water evaporates at point Q,
The temperature of the rice rises rapidly as shown in the figure. The thermistor placed in contact with the bottom of the inner pot detects this rising temperature at the R point of 130°C, and the heating amount control circuit is activated to reduce the output of the bottom heater 4 to almost zero, and the unevenness process begins. . When the temperature drops during the unevenness process, the bottom heater is turned on again at point 8. When the predetermined time tl has passed during the unevenness process,
The body heater 6 and lid heater 5 are turned on to enter the heat retention process, and the heat retention process continues thereafter.

のである。Note that all the operations of the rice cooker in the rice cooker process described above are automatically performed by a control program stored in the control device of the rice cooker. Therefore, the user simply puts a predetermined amount of rice and water into the inner pot and presses the switch on the rice cooker, and after a predetermined period of time, the rice is kept warm.
また上記内がまは炊飯中、その底部の所定位置が炊飯器
の所定接点と当接しており、その当接の有無は制御や安
全の面に利用されている。Further, during rice cooking, a predetermined position on the bottom of the inner pot contacts a predetermined contact point of the rice cooker, and the presence or absence of this contact is used for control and safety.

炊飯器のヒータその他は保温状態に戻る。[Problems to be Solved by the Invention] By the way, when the inner pot of the rice cooker that is in the process of keeping warm while cooking rice is lifted by the rice cooker, that is, when the contact between the inner pot and the contact point disappears, as soon as the rice cooker stops keeping warm. Control of the process ceases, but the memory of being kept warm remains. Therefore, when the lifted inner pot is attached to the rice cooker and the contact is restored,
The heater and other parts of the rice cooker return to their warm state.

After that, when the rice cooking process starts and the warming process starts, if you lift the inner pot 3 (step 2), the control will stop immediately (
However, the memory of being kept warm remains (step 4). Once the rear lock is attached (step 5)
), control is resumed but it remains warm (
Step 7). The memory of the thermal insulation state continues unless the lifted inner jacket is put on (Step 6).

うっかりした使用者により時々繰り返されてきたため、
かねてよりその対策が要望されていた。A conventional rice cooker control program is configured as described above. Therefore, in a rice cooker that is in the process of keeping warm, there is no problem if the lifted inner pot is returned to the keeping warm state, but for example, if the inner pot that is in the keeping warm state is removed from the rice cooker,
If you add new rice and water to the rice cooker after processing the rice inside and try to cook rice, press the cancel button to cancel the memory of the warm state and do not press the rice cooking start button again. However, if you just put the inner pot back into the rice cooker, the rice cooker will return to its memorized warming process when you put it back, so the rice in the inner pot will be raw. As these cases have been repeated from time to time by careless users,
Countermeasures have been requested for some time.
本発明は上記問題点を解消するためになされたもので、

ムを次のように構成した。[Means for Solving the Problems] In order to achieve the above object, the rice cooker according to the present invention includes a heat retention process determining means, and a control program for the heat retention process is configured as follows.
すなわち上記判定手段により内がまの持ち上げ時点が保
温過程内ではないと判定されたときは、内がまが炊飯器
に装着され次第制御を再開する。That is, when the determination means determines that the time at which the inner pot is lifted is not within the warming process, the control is resumed as soon as the inner pot is attached to the rice cooker.
内がまの持ち上げ時点が保温過程内であると判定された
ときは、内がまが持ち上げられた時点でタイマを作動し
、所定時間内に内がまが装着されれば内がまの持ち上げ
以前の過程を再開するが、所定時間内に内がまが装着さ
れなければ、保温制御を停止する。If it is determined that the time when the inner pot is lifted is within the warming process, a timer is activated when the inner pot is lifted, and if the inner pot is attached within a predetermined time, the inner pot is lifted. The previous process is restarted, but if the inner pot is not attached within a predetermined time, the heat retention control is stopped.

ステップ１７）。If the time of lifting the inner pot is not within the warming process, it is further determined whether or not the inner pot is attached to the rice cooker (Step 18), and if it is attached, the control is resumed (Step 1).
). If the time when the inner pot is lifted is within the warming process, the timer is activated (step 14), but if the inner pot is attached immediately, the timer is activated (step 15), and if the inner pot is attached immediately, the control is resumed (step 1). ). However, time passed while the inner pot was lifted, and 30 minutes passed without the inner pot being attached.
When the seconds pass (step 16), the heat retention control is stopped (
Step 17).

いて内がまを持ち上げて内がま未装着のまま３０秒経過
すれば保温制御は停止し、スタート以前の状態に戻る。In the control program according to the present invention, if the inner pot is lifted during the heat retention process and 30 seconds elapse without the inner pot being attached, the heat retention control is stopped and the state returns to the state before the start.
したがって保温過程の内がまを炊飯器から取り出し米飯
を処理した後、新しく米と水を内がまに入れて炊飯する
などのように時間を要する場合は、炊飯器はスタート以
前の状態に戻っているので、保温状態で炊飯して生炊き
するなどの恐れはなくなる。Therefore, if it takes a long time, such as when you take the inner pot out of the rice cooker during the warming process and process the cooked rice, then add new rice and water to the inner pot and start cooking, the rice cooker will return to the state before starting. Therefore, there is no need to worry about cooking rice while keeping it warm and cooking it raw.
なお上記経過時間は本実施例においては３０秒であるが
、この数字に限定するものではない。Note that although the elapsed time is 30 seconds in this embodiment, it is not limited to this number.
