When it is determined whether or not the rice cooking key 4 is turned on, the changed rice cooking conditions are reflected in the rice cooking control program. As a result, it is possible to prevent the rice from being cooked with the incorrect setting of the rice cooking condition due to the erroneous detection of the setting key 7 from the previous cooking to the present time, and the setting by the setting key 7 must be reset. It is possible to improve the inconvenience that it must be.

Embodiment 7 FIG.
In the first embodiment, after the closure of the lid 3 is detected, the input of the setting key 7 is permitted. However, in the seventh embodiment, the closure of the lid 3 is detected and the rice cooking key 4 is turned on. Is detected, the input of the setting key 7 is permitted.
The block configuration in the seventh embodiment is the same as the block diagram shown in FIG.

  The control means 31 executes the rice cooking control program based on the rice cooking conditions set by the capacitance type setting key 7 and controls the heating means 24 according to the temperature detection of the temperature detection means 25. The rice cooking control program is executed when the mechanical rice cooking key 4 is turned on. Moreover, the control means 31 permits the input of the capacitance type setting key 7 when the lid opening / closing detection means 16 detects the closing of the lid 3 and detects the ON of the rice cooking key 4. The control means 31 cooks rice when it detects that the rice cooking key 4 is turned on again after giving permission to input the setting key.

Here, the operation of the control means 31 in the seventh embodiment will be described with reference to FIG.
FIG. 16: is a flowchart which shows operation | movement of the control means of the rice cooker which concerns on Embodiment 7 of this invention.
The control means 31 first determines whether or not the lid 3 is closed (S61). The control means 31 prohibits input from the setting key 7 when the lid 3 is open (S62), and determines whether the rice cooking key 4 is turned on when the lid 3 is closed (S63). When the rice cooking key 4 is not turned on, the process returns to S61 and the above-described operation is repeated. The control means 31 permits the input from the setting key 7 when detecting the ON of the rice cooking key 4 in S63 (S64). When the control means 31 permits the input from the setting key 7, it determines again whether the rice cooking key 4 is turned ON (instruction to start rice cooking) (S65).

  When the rice cooking key 4 is not turned on, the control means 31 returns to step S64 and permits input from the setting key 7. Moreover, when the control means 31 detects ON of the rice cooking key 4 in step S65, based on the rice cooking conditions set by the setting key 7, it performs a rice cooking control program and cooks rice (S66). When there is no input from the setting key 7 and the rice cooking key 4 is turned on, the rice cooking control program is executed based on the previous rice cooking conditions.

  As described above, according to the seventh embodiment, the input of the setting key 7 is prohibited while the lid 3 is open, and the setting key 7 is turned on after the rice cooking key 4 is turned on while the lid 3 is closed. Is allowed to input. Thus, when the lid 3 is in the closed state, when the rice cooking key 4 is detected to be turned on, input of the rice cooking conditions by the setting key 7 is accepted. It is possible to reduce acceptance of erroneous operations.
