I have to do it. For this purpose, it is necessary to subtract the required cooking time (meaning the total time of each of the steps of weighing, washing and rice cooking) from the pre-set cooking time, and calculate the weighing start time back.

Conventionally, the rice cooking time to be subtracted has been determined by the rice cooking time setting means from the rice cooking conditions (the amount of rice cooked, the degree of hardness, the degree of washing, etc.) set by the rice cooking condition setting means. However, the rice cooking time setting means,
The actual rice cooking time was calculated by the rice cooking time setting means because the rice cooker device having the sub-controller was programmed for the rice cooker device without the sub-controller. It took longer than

Therefore, there is a problem that the cooked time is later than the reserved time. On the other hand, when entering the rice drying process, the remaining time until the rice drying process is completed is displayed by the remaining time display means. Was carried out after the detection of Therefore, when a device having a sub-control device as a rice cooker and performing a post-cooking process after so-called dry-up in which the water in the kettle has been used is used, the remaining remaining time during the post-cooking process is displayed. As a result, there was a problem that the unevenness time was not executed as set.

[0007] That is, according to the conventional rice cooker device, depending on whether the rice cooker device to be used has the sub-control device or not, the cooker does not cook at the reserved cooking time or the remaining time display of the spot is not accurate. There was a problem that time management was not performed accurately. Therefore, the present invention

The rice cooking time setting means 34 calculates the rice cooking time (total time of weighing, washing rice, cooking rice, and rice porridge) based on various conditions set by the rice cooking condition setting means 32 by a previously installed arithmetic program. It is. The start time setting means 35 performs the processing shown in FIG. That is, when a reservation operation of a cooking time is performed by the reservation means 31, it is determined whether or not the rice cooker device 4 has a pre-cooking step. This pre-cooking process is one of the rice cooking processes controlled by the sub-control device 10 of the rice cooker device 4.
This is the process of lowering the heat to cook rice in the early stage of rice cooking, as is called medium papper. When the rice cooker device 4 has a pre-cooking step, the start time is obtained by the following equation.

Start time = reservation time-rice cooking time-pre-cooking time If there is no pre-cooking step, start time = reservation time-rice cooking time is obtained. Then, when the obtained start time comes, an operation start command is issued to the weighing device 2 and the like via the operation command means 36, and the rice cooking operation (a series of operations of weighing, washing and rice cooking) is started.

FIG. 3 is a flow chart for displaying the remaining blur time. The remaining time display processing is performed as follows. That is, when the rice cooking process proceeds in the rice cooker device 4 and the water in the kettle is depleted, the temperature of the kettle rises sharply. This rise in temperature is detected by dry-up detecting means 37 (see FIG. 1) composed of a temperature sensor or the like, and a state in which the water in the kettle has run out, that is, a so-called dry-up is detected. The main controller 5 is programmed to determine that the rice cooking process has been completed based on the detection of the dry-up, and to enter the next washing process.

However, when the rice cooker device 4 has an additional cooking process, the secondary controller 10 controls the additional cooking process to proceed after detecting the dry-up. Process and sub-control device 1
Since the re-cooking process by 0 proceeds at the same time, the display of the remaining remaining time becomes inaccurate. Therefore, the rice cooker 4
If there is a re-cooking process, the remaining time of the spots is determined by the following equation.

Remaining time = additional cooking time + irregularity time-elapsed time The additional cooking time is the additional cooking time set by the sub-control device 10, and the irregularity time is the irregularity time setting means. The elapsed time is the time after the detection of the dry-up. And
If the rice cooker device 4 does not have a follow-up cooking process, the remaining time of spotting is determined as: remaining time = time of spotting-elapsed time.

The remaining time thus obtained is displayed on the remaining time display section 20. It should be noted that the remaining time display means 38 (see FIG. 1) of the present invention is constituted by the remaining time display section 20 and an arithmetic means. Note that the present invention is not limited to the specific examples described in the above embodiments.
