It is checked whether the temperature is 6 ° C. or more. If the pot temperature T0 is 106 ° C. or more even after 10 minutes have passed, it is determined that the rice cooking is normal for a time, and then the clocking circuit 46b sets a 5-minute swing. When this spotting is completed, the operation is shifted to heat retention.

In this heat retention, the rice cooker lamp 16 of the various displays 19 is turned off and the heat retention lamp 17 is turned on via the output circuit 51 in the same manner as described above. Further, the thyristor driving circuit 48 is controlled, and the thyristor driving circuit 48 controls the conduction of the thyristor 44 to start the energization control of the body heater 25 and the lid heater 26.

When the time t2 of the time counting circuit 46b is 10
If the pot temperature T0 detected by the pot sensor 5 drops below 106 ° C. before the minute, the rice cooker 4 is judged to be abnormal and the rice cooker 4 is turned on at a heating value of 70% W to continue the rice cook operation. Let it. Thereafter, when the pot temperature T0 detected by the pot sensor 5 reaches 122 ° C. or higher, the rice cooking heater 4 is turned off.

Thereafter, a 10-minute swing is set by the time counting circuit 46b, and when the unevenness ends, the temperature is shifted to the heat retention. In this heat retention, the rice cooker lamp 16 of the various displays 19 is turned off via the output circuit 51, and the heat retention lamp 17 blinks.

And the energization control of the lid heater 26 is started.

The microcomputer 46 is shown in FIG.
The following container cleaning control is performed.
This is started by operation of the container / lid switch 22. That is, when the container / lid switch 22 is turned on, it is checked whether or not the rice cooker / off switch 20 is in the off state. If not, the cleaning is invalidated and the control up to that point is continued. If it is off, the rice cooker 4 is turned on. When the pot temperature T0 detected by the pot sensor 5 reaches 110 ° C. or higher, the rice cooker 4 is turned off.

Then, one minute is counted by the timing circuit 46b.
After a lapse of minutes, the cooling fan 30 is operated. Thereby, the rice cooker main body 1 including the pan 6 is cooled. Thereafter, when the pan temperature T0 detected by the pan sensor 5 becomes 50 ° C. or less,
The cooling fan 30 is turned off and the buzzer 52 is turned on for a predetermined time.

That is, this checks whether or not the rice cooker / off switch 20 is in the off state. If not, the cleaning is invalidated and the control up to that point is continued. If it is in the off state, it is checked whether the detected temperature T1 of the lid sensor 27 is lower than 110 ° C., and if the detected temperature T1 exceeds 110 ° C., the cleaning is invalidated and the control up to that point is continued. . If the detected temperature T1 is 11
If the temperature is 0 ° C. or lower, the lid heater 26 is turned on. Wait until the detected temperature T1 detected by the lid sensor 27 reaches 120 ° C. or higher.
Turn off.

Then, one minute is counted by the timing circuit 46b.
When the minute has elapsed, the buzzer 52 is turned on for a predetermined time. The container cleaning control shown in FIG. 6 and the lid cleaning control shown in FIG. 7 constitute cleaning heating control means.

The microcomputer 46 is shown in FIG.
The following cooling control is performed. This is started by operating the cooling switch 23. That is, this checks whether the rice cooker / off switch 20 is in the off state, and if not, disables the cooling and continues the control up to that point. If it is off, the cooling fan 30 is operated. Thereby, the rice cooker main body 1 including the pan 6 is cooled. Thereafter, when the pan temperature T0 detected by the pan sensor 5 becomes 50 ° C. or lower, the cooling fan 30 is turned off and the buzzer 52 is turned on for a predetermined time.

In the embodiment having such a configuration, the pan 6
When a predetermined amount of rice and water are put into the rice cooker and the rice cooker / off switch 20 is operated, the normally open contact 43m of the relay 43 is turned on and the power supply to the rice cooker heater 4 is started. In this way, the first cooking is started. The rice cooker lamp 16 is turned on.

After three minutes have elapsed, the power supply to the rice cooker 4 is stopped, and the apparatus waits for seven minutes in this state. When seven minutes have elapsed, the rice cooking is finished, the rice cooking heater 4 is turned on again, and rice cooking is started. The timing circuit 46
b starts counting the time t1. When rice cooking is started, the temperature of the pot 6 gradually rises, and the pot temperature T0 detected by the pot sensor 5 eventually reaches 105 ° C. or higher, which is the cooking temperature. When the pot sensor 5 detects 105 ° C. or higher, the cooking is determined and the calorific value of the rice cooker 4 is reduced to 60% W.

Even if the calorific value of the rice cooker 4 decreases, the temperature of the pot 6 rises little by little, and when the water in the pot runs out, the pot temperature T0 rapidly rises. Then, when the pot sensor 5 detects 120 ° C. or higher, which is the temperature at which rice cooking should be finished, the rice cooking heater 4 is turned off.

At this time, if the counted time t1 of the timing circuit 46b is 10 minutes or more, it is determined that the rice cooking has been normally performed, and then the rice is cooked for 15 minutes.

However, if the time t1 of the timer circuit 46b has not reached 10 minutes due to an abnormality of the pan sensor 5, etc., it is determined that an abnormality has occurred in the pan sensor 5. Then, the timer circuit 46b starts counting a new time t2.

By the time the time counting circuit 46b counts 10 minutes, the pot temperature T0 detected by the pot sensor 5 is 106 ° C.
If the temperature does not drop below, it is determined that the rice cooking has been performed normally, and after that, the rice is heated for 5 minutes, and then the operation is shifted to heat retention. That is, the fact that the pot temperature T0 does not drop below 106 ° C. means that there is almost no residual water in the pot 6 and there is no need for reheating, the amount of water for rice is small, or the voltage is high and the rice cooker 4 It is determined that the rice cooking time was short due to a large amount of heat generation and the rice cooking is not continued.

Further, at this time, the power supply to the rice cooker 4 is stopped, and then the pot temperature T0 is set to 106 ° C. for 10 minutes.
Since it is checked whether it drops below 10 minutes, by setting a steaming time of 5 minutes and moving to heat retention after 10 minutes, it is substantially equivalent to setting a spot of 15 minutes. In addition, it is possible to shift to heat retention without lengthening the time required for spotting.

If the pot temperature T0 detected by the pot sensor 5 may drop below 106 ° C. by the time the time counting circuit 46b counts 10 minutes, the pot sensor 5 will be higher than the original temperature detection state. It is determined that an abnormality has occurred in the cooked rice due to the detection of the temperature. That is, pot sensor 5
If the temperature of the rice is detected higher than the original temperature detection state, the rice cooking may end even though a large amount of water still remains in the pan 6, and then the rice cooking heater 4 is turned off when the rice cooking heater 4 is turned off. The temperature drops relatively quickly to around 100 ° C.

Therefore, the rice cooker 4 is turned on again upon detecting the temperature drop. That is, the rice cooking heater 4 is turned on at a heating value of 70% W to continue the rice cooking operation.

Thereafter, when the pot temperature T0 detected by the pot sensor 5 reaches 122 ° C. or higher, the rice cooker 4 is turned off to finish the rice cooking. Then, in this case, the warming lamp 17 is flashed to notify the user.

FIG. 9 is a graph showing the change over time of the temperature of the pot at the time of abnormal rice cooking as shown by a solid line in FIG. In addition, the dotted line graph d shows the time change of the pot temperature when the initial cooking time t1 was short, but the pot temperature T0 did not drop below 106 ° C. in the subsequent 10 minutes, that is, when it was judged to be normal once. Is shown.

As described above, even if an abnormality occurs in the temperature detection of the pot sensor 5 and the rice cooking time is controlled to be shorter than the original rice cooking time, the calorific value of the rice cooking heater 4 is reduced by 70%.
Since the rice cooking time can be continued in the state of% W and the rice cooking can be surely terminated, it is possible to prevent the worst case in which the rice cooking is completed without the sufficient rice cooking. In other words, even if such a situation occurs, relatively good rice can be cooked.

Further, the user can be informed that abnormal cooking has occurred by blinking of the heat retention lamp 17, so that the user can know that the abnormal cooking has occurred and can take any countermeasure against it. Become.

In addition, steam is generated in the pot 6 during rice cooking and steaming. With this vapor pressure, the valve 32 of the vapor discharge section 11 is pushed up. Then, the steam is discharged from the hole 31 through the steam discharge portion 11.
The gas is discharged to the outside through the hole 36a through the inside.
In addition, since the hole 31 is closed by the valve 32 and the inner plate 9 of the lid 8 and the valve 32 are heated by the lid heater 26 during heat insulation, the vicinity of the hole 31 provided in the inner plate 9 is cooled by the outside air. Thus, it is possible to prevent a situation in which dew condensation occurs in that portion.

Therefore, it is possible to prevent a situation in which water drops drop on the cooked rice caused by the provision of the steam discharge unit 11 and the taste of the rice drops, and the temperature in the pot during the heat insulation cannot be made uniform. it can.

Since the shaft 33 and the valve 32 can be easily taken out of the steam discharge section 11 by removing the cap 36, the cleaning is simple.

When the rice in the pot 6 has been eaten in the warm state, the pot 6 and the inner plate 9 of the lid 8 are washed.
On the inner surface plate 9, a glue-like material called rice cake formed by dissolving rice starch in water is difficult to adhere.

Then, the container / lid switch 22 is operated.
The switch 22 alternately selects between container cleaning and lid cleaning.
Is operated once, the container cleaning heating control is started, and when it is operated twice, the lid cleaning heating control is started.

In the container cleaning heating control, the pot 6 is heated to 110 ° C. or higher by the rice cooking heater 4. As a result, the ash attached to the pan 6 dries to form a film and can be easily peeled off. After the pan 6 is kept at 110 ° C. or higher for one minute, the cooling fan 30 operates and air is sucked into the inner frame 2 from the outside through the rice cooker main body 1 and the reflecting plate 3 as shown by a dashed line in FIG. Then, the pan 6 is cooled and the user is notified by a buzzer when the pan temperature becomes 50 ° C. or less.

In the lid cleaning / heating control, the inner plate 9 is heated to 120 ° C. or more by the lid heater 26. As a result, the ash attached to the inner surface plate 9 dries to form a film and can be easily peeled off. After the inner plate 9 is kept at 120 ° C. or higher for one minute, the user is notified by a buzzer.

The tongue and inner plate 9 thus attached to the pan 6
Since the ash attached to the pan can be easily peeled off by drying, if it is peeled off and removed before washing, the washing of the pot 6 and the inner face plate 9 becomes extremely easy.

Further, when only the pan 6 is to be cooled, the cooling switch 23 may be operated. As a result, the cooling fan 30 operates, and when the temperature of the pan falls to 50 ° C. or less, the cooling fan 3
0 is stopped and the user is notified by a buzzer.

[0066] Incidentally, the use of the lid sensor 27 as the lid cleaning heating control in the embodiment, although to perform the energization of the lid heater 26 until the detected temperature T1 of the cover sensor 27 becomes equal to or higher than 120 ° C. necessarily However, the present invention is not limited to this. As shown in FIG. 10, the lid cleaning heating control may be performed by applying power to the lid heater 26 for 5 minutes without using the lid sensor 27.

The structure of the steam discharge section 11 is not limited to the above embodiment, but may be the structure shown in FIGS. 11, 12 and 13.

That is, FIG. 11 shows a pipe 6 made of aluminum material on a convex portion 9a formed on a part of the inner surface plate 9.
1 is provided in a detachable manner, a valve 62 is provided above the pipe 61, and the pipe 61 is provided with a cap 63 having a hole 63 a.
It is configured to hold it.

FIG. 12 shows an example in which one end of a pipe 64 made of an aluminum material is fixed by caulking to a hole 31 provided in a convex portion 9a formed in a part of the inner face plate 9, and The other end opening is closed with a valve 65 made of aluminum die-cast, and a cap 66 provided with a hole 66a is put on the valve 65.
