本発明は、炊飯器のヒータと炊飯容器上の間に異物が入
ったような場合に、ヒータの加熱を遮断することなく安
全に炊飯を完了し得る炊飯器の制御手段を提供すること
を目的とするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a rice cooker control system that allows rice cooking to be completed safely without cutting off heating of the heater when a foreign object enters between the heater of the rice cooker and the top of the rice cooking container. The purpose is to provide a means.
炊飯器のヒータと炊飯容器の間に飯粒のような異物が挾
み込まれると、ヒータの熱が容器に伝わりにくく、ヒー
タ近辺の温度が高くなり、鋳造材料が溶融するなどの危
険が生じる。If a foreign object such as a grain of rice is caught between the heater of a rice cooker and the rice cooking container, the heat of the heater will be difficult to transfer to the container, and the temperature near the heater will rise, creating a risk of melting of the casting material.
そのため従来は温度ヒユーズなどの安全素子によってヒ
ータの加熱を停止する手段がとられている。Conventionally, therefore, measures have been taken to stop the heating of the heater using a safety element such as a temperature fuse.
しかしこの方法では安全性は確保されるが、炊飯ができ
ない欠点がある。However, although this method ensures safety, it has the disadvantage that rice cannot be cooked.
本発明は、容器とヒータの間に異物が入った場合、容器
の温度上昇が少ないことを利用して、容器の温度を予め
２点設定しておいて、この温度の間を通過する時間を計
数し、これを基準時間と比較し、基準時間より多くかか
る時は、異物が挾まれたものとしてヒータの加熱量を低
減して以後の炊飯を継続するようにしたものである。The present invention takes advantage of the fact that when a foreign object enters between the container and the heater, the temperature of the container does not rise much.The temperature of the container is set in advance at two points, and the time it takes to pass between these temperatures is taken advantage of. This is counted and compared with a standard time, and if it takes longer than the standard time, it is assumed that a foreign object has been caught, and the heating amount of the heater is reduced to continue cooking the rice thereafter.
低減した加熱量は、ヒータ近辺の温度が危険が生じない
程度の温度上昇値で、且つ炊飯可能な値に設定する。The reduced heating amount is set to a temperature rise value that does not pose a danger to the temperature near the heater, and is set to a value that allows rice to be cooked.
以下図面を参照して本発明の詳細な説明する。The present invention will be described in detail below with reference to the drawings.
図は本発明の一実施例の回路である。The figure shows a circuit of one embodiment of the present invention.
図において１は交流電源、２は既知の感温フェライトを
使用したサーモスイッチで炊飯が完了すると自動的に開
かれるように構成されている。In the figure, 1 is an AC power supply, and 2 is a thermoswitch using a known temperature-sensitive ferrite, which is configured to be automatically opened when rice cooking is completed.

成されている。3 is a heating amount control device, 4 is a heater, the heater 4 is connected to the AC power source 1 via the triac 5 of the heating amount control device 3, and the firing angle of the triac 5 is when the switch 9 is on the A side. It is determined by the resistor 6, the capacitor 7, and the diac 8, and when the switch 9 is switched to the B side, the resistor 10 with a larger resistance value is switched in place of the resistor 6, so that the amount of current flowing through the triac 5 is reduced. It is configured.

、加熱量を低減するように構成されたものである。11 is a rice cooking container; 12 is a temperature detection device composed of a thermistor or the like that detects the temperature of the container 11; 13 is a temperature detection device 12 that starts a timer argument when the temperature detected by the temperature detection device 12 is a predetermined temperature; A timer device that continues counting until a second predetermined temperature higher than the previous temperature is reached and stops the argument at this temperature; 14 is a comparison device that compares the counted value argumented by the timer device 13 with a reference value; This comparison value is long,
That is, when the time required for the container 11 to pass through two temperature points is longer than the reference time, the switch 9 is switched to the B side to reduce the amount of heating.

ているので、切換スイッチ９の接点はＡ側のままで、炊
飯が行なわれる。Now, when the container 11 containing rice and water is normally set on the heater 4 and the switch 2 is closed, the heat of the heater 4 will be transferred to the container 1.
At this time, the switch 9 is on the A side, and the container 1 is
1, the temperature rises relatively quickly, the time it takes to pass between the two predetermined temperatures is short, and the temperature is below the reference value of the comparator 14, so the contact of the changeover switch 9 remains on the A side. , rice is cooked.

炊飯器本体の温度上昇は比較的低く抑えられ、危険が回
避される。Next, when there is a foreign object between the container 11 and the heater 4,
When you start cooking rice in this state, the heat from the heater 4 is transferred to the container 11.
Since the temperature of the container 11 is not sufficiently transmitted, the slope of the temperature rise in the container 11 becomes gradual, and if rice cooking continues at the same heating amount, the temperature of the heater 4 and the rice cooker itself will rise, which is dangerous. Since the slope is gentle, the count value of the timer 13 becomes dog, the comparator 14 operates, the contact of the changeover switch 9 is switched to the B side, and the heating amount of the heater 4 is reduced by the heating amount control device 3. The temperature rise of the heater 4 and the rice cooker body is suppressed to a relatively low level, and danger is avoided.
又ヒータの加熱量は零にはならないので、正常炊飯時に
比べて炊き上げ状態は劣るが炊飯は完了される。Also, since the heating amount of the heater does not reach zero, the rice cooking is completed, although the cooked rice is not as good as it is during normal rice cooking.
このようにして本発明によれば、ヒータと炊飯容器の間
に異物が入って正常に容器がセットされない場合にも危
険を生じることなく、且つ炊飯を完了することができる
。In this way, according to the present invention, even if a foreign object enters between the heater and the rice cooking container and the container is not properly set, rice cooking can be completed without causing any danger.
