OFF control (output control) is performed.

The microcomputer control unit 50
For example, a basic rice cooking control program as shown in a flowchart (S _{1 to} S ₆ ) of FIG.
When Wa is turned on, water is absorbed, cooked, spotted as shown in the flowchart of FIG.
Each specific control process of the heat retention is appropriately executed.

[0039] That is, when the current cooking switch SWa is turned ON, enters the water absorption step, first step S ₁ in detected by the thermistor 7a the rice device temperature T is the reference temperature 40 ° C. or less in the water absorption step of FIG. It is determined whether or not. Then, as a result, the rice cooker temperature T is 40 ° C. or less (YE
In the stage immediately after the start of water absorption in S), the process proceeds to steps S ₂ , S ₃ , and S ₄ in order, and the output duty of the rice cooker 8 is 6/14, the output duty of the heat retention heater 20 is 8/14, and the lid. The output duty of the heater 17 is 6 /
The heating of the rice cooker is performed by setting each to 14. As a result, the rice cooker temperature T quickly rises to around 40 ° C.

On the other hand, it is determined in step S ₁ that the rice cooker temperature T has reached a temperature exceeding the water absorption reference temperature of 40 ° C.
When it is determined that the water absorption temperature is 40 ° C., the process proceeds to steps S ₅ , S ₆ , and S _{7 in order} to turn off the rice cooking heater 8 and the warming heater 20 and turn on only the lid heater 17. And set time t for the water absorption process
Water is absorbed within ₁ (t ₁ = 500 seconds).

[0041] Then, at the next step S _8, the course of the water absorption process set time t ₁ (t ₁ = 0) is determined, then the process proceeds to step _{S 9, S 10, S 11} , sequentially cooking heater 8 By turning on the respective output duties of the heat retaining heater 20 and the lid heater 17 at 12/14, 12/14 and 6/14, the whole of the rice cooker 4 and the heat radiating plate 5b are effectively and uniformly heated with a sufficient heating amount. By doing so, the cooking process of FIG. 5 is executed. Cook up heating control of step S ₉ to S ₁₁ continues at step S _12, the temperature T of rice device 4 that has become raised completion temperature 130 ° C. or higher cooking is repeated until it is determined (NO judgment).

[0042] On the other hand, the determination result of the step S ₁₂ is NO
Becomes (T = 130 ° C. over), cooking the completion of raising is determined, followed by setting the flow proceeds to step S ₁₃ time t
₂ = Display the irregular process of 12 minutes (720 seconds)
Steaming enters the process, intended to make subtraction (decrementing) of the same time in each cycle in step S _14.

[0043] Then, in step S ₁₅ in between, or less than rice device temperature T Gamurashi temperature 110 ° C., to determine higher than for each cycle, at the YES (110 ° C. or less), steps Proceeding to S ₁₆ , S ₁₇ , and S ₁₈ , the output duties of the rice cooking heater 8, the heat retaining heater 20, and the lid heater 17 are sequentially adjusted to 2/14, 8/14, and 6/14, and the uneven temperature of 110 ° C. Attempt to maintain. On the other hand, when the temperature T of the rice cooker 4 has not yet fallen below the spotting temperature of 110 ° C., the rice cooking heater 8 and the warming heater 20 are first turned off in steps S ₁₉ and S ₂₀ , while the lid is turned off in step S ₂₁ . Only the heater 17 is turned on with an output duty of 2/14 to quickly shift to the set uneven temperature 110 ° C.

[0044] Then, the process proceeds to step S ₂₂ on them, the steaming process set time t ₂ = 12 min (120 sec)
Determining the course of, at the YES (t ₂ = 0 has elapsed), ring the buzzer to notify completion of cooking in step S _23.

[0045] Thereafter, further proceeds to step S _24, whether the temperature T of the rice unit 4 is lowered to set retained temperature 72 ° C. or less, it is determined whether, the insulation heater 20 in the case of YES at step S ₁₂ output duty to 6/14 and the output duty of the lid heater 17 at step S ₂₆ 2/1
4 to perform an effective heat retention process utilizing the features of the heater plate structure. On the other hand, when the still rice device temperature T has not decreased to the set retained temperature 72 ° C. or less, once OFF the insulation heater 20 at step S ₂₇
As well as to set the 2/14 output duty of the lid heater 17 at step S _28, promote a shift to set it retained temperature 72 ° C. in either quickly by reducing the amount of heating.

Then, as described above, the heat retention around the temperature of around 72 ° C. is executed.

[0047] On the other hand, during the incubation, for example, thermal insulation cancel switch SWb in step S ₂₉ that has been turned ON is determined, also ends the incubating process.
