FIG. 8 shows the operation in the cleaning mode.
In the cleaning mode, first, it is determined whether or not the current time is the automatic cleaning start time (time determination step S1). That is, in the time determination step S1, it is determined whether or not the current time is the reservation time set by the cleaning reservation function (automatic cleaning function). If the current time is the reserved time, it is determined whether the rice washing operation of the rice by the rice washing tank 12 is not performed (rice washing operation determination step S2). In the rice washing operation determination step S2, for example, when either the metering drive device 8 that rotates the metering unit 9 or the stirring drive device 50 that rotates the stirring member 21 is operating, it is determined that the rice washing operation is being performed. (S2, No). In addition, any of the lifting device 30 that lifts and lowers the rice drain valve 28, the opening and closing valve 53 of the water supply unit 15, and the opening and closing drive device 45 that moves the interlocking member 42 downward is operating to perform the rice washing. However, it is determined that the rice washing operation is being performed (S2, No).

That is, in the rice washing operation determination step S2, the above-described various devices are in an operation for performing the rice washing operation (for example, when a program that performs the rice washing operation is operating in the control unit 16). If so, it is determined that the rice washing operation is being performed (S2, No), and if it can be determined that the rice washing operation is not being performed (S2, yes), the process proceeds to the next.
In the washing mode, when the rice washing operation is not performed (rice washing operation determination step S2, yes), it is determined whether or not the operation is reserved by the operation reservation function (operation reservation determination step S3). It is determined whether or not the reserved time and the washing time when back-calculated from the time set for the driving reservation function (cooking time) do not overlap (reserved time determination step S4).

Here, when the reservation time in the cleaning reservation function coincides with the rice washing time in the driving reservation function (reservation time determination step S4, yes), the cleaning mode is terminated and the operation proceeds to the rice cleaning operation. In other words, the washing mode includes a rice washing priority process that prioritizes the rice washing operation when the reservation time in the washing reservation function overlaps with the rice washing time in the operation reservation function. Prioritize work efficiency.
Next, in the cleaning mode, when the rice washing operation is not performed and the reservation time in the cleaning reservation function and the rice washing time in the operation reservation function do not overlap, the display unit 70 of the display device 11 performs the cleaning. Is displayed (for example, S5 indicating that the tank is being cleaned is displayed on the display unit). As a matter of course, any display content may be displayed on the display unit 70 as long as it is understood that the cleaning is performed.

Then, the opening / closing drive device 45 is driven by the command signal to move the interlocking member 42 upward (S6), thereby bringing the opening / closing member 35 into the closed position. It is determined whether or not the opening / closing drive device 45 has been driven for a predetermined time (for example, 7 seconds) (S7), and if the predetermined time has passed, the process proceeds to the next process. By operating the opening / closing drive device 45 for a predetermined time, the opening / closing member 35 can be reliably closed.
In the cleaning mode, after calling the flow rate (scheduled water supply amount) and the water supply time (scheduled water supply time) discharged from the water supply unit 15 from the storage unit (inert memory) provided in the control unit 16 (S8), the water supply unit 15 Is opened and water is supplied from the water supply nozzle 51 to the rice washing tank 20 (S9). In this step, counting of actual water supply amount and actual water supply time (measurement, measurement) is started.

  It is determined whether or not the actual water supply amount from the start of water supply by the water supply nozzle 51 has reached a preset predetermined water supply amount (water supply determination step S10). When the actual water supply amount has not reached the planned water supply amount (for example, 5 L), it is determined whether or not the actual water supply time after starting the water supply by the water supply nozzle 51 has reached the planned water supply time (S11). If the actual water supply time has not reached the planned water supply time, the process returns to the water supply amount determination step S10. If the actual water supply time has reached the planned water supply time, the process proceeds to the next process. Further, when the actual water supply amount reaches the planned water supply amount, the process proceeds to the next process. And the on-off valve 53 of the water supply part 15 is closed, and the supply of the water to the rice washing tank 20 from the water supply nozzle 51 is stopped (S12).

By the process of step 9 (S9)-step 12 (S12), the process which accumulates water in the rice washing tank 20 in order to wash is performed (water supply storage process). In the state where water is accumulated in the rice washing tank 20, water is temporarily stored in the drainage jacket 13 and the pipe 34, and water is accumulated in the path from the drainage jacket 13 to the drainage box 14. Yes.
Next, the actual water supply amount and the actual water supply time are cleared (reset to zero) (S13), and the stirring drive device 50 is driven by the command signal to rotate the stirring member 21 (stirring washing step S14). The time when the stirring drive device 50 is driven (time after the stirring drive device 50 starts driving), that is, the time when the stirring member 21 is rotated (time after the stirring member 21 starts rotating) is the time. It is determined whether or not a predetermined scheduled driving time (for example, 10 seconds) has been reached (S15).

When the time when the stirring drive device 50 is driven (the time when the stirring member 21 is rotated) becomes the scheduled drive time, the stirring drive device 50 is stopped and the opening / closing drive device 45 is stopped by a command signal to move the interlocking member 42 downward. This is moved, thereby opening the opening / closing member 35 (drainage step S16).
Then, it is determined whether or not the time after the opening / closing drive device 45 is stopped (the time after the opening / closing member 35 is opened) has reached a preset minimum opening time (for example, 60 seconds) (S17). ). When the time after the opening / closing member 35 is stopped (the time after the opening / closing member 35 is opened) becomes the minimum opening time, the stirring driving device 50 is driven again to restart the rotation of the stirring member 21. (S18).

A display indicating that the cleaning is completed is displayed on the display unit 70 of the display device 11 (for example, S19 indicating that the cleaning is completed on the display unit). As a matter of course, any display content may be displayed on the display unit 70 as long as the cleaning is completed.
Further, a notification unit 81 such as a buzzer provided in the display device 11 is operated to generate a sound indicating that the cleaning is completed (S20). The sound generation by the notification unit 81 is performed for a predetermined time (for example, 5 seconds, S21). And when predetermined time passes, the display which is the state before a driving | running | working will be performed on the display part 70 of the display apparatus 11. FIG. That is, the rice cooker 1 is returned to the state before the cleaning operation (S22).

When the cleaning is completed, it is determined whether or not driving is reserved by the driving reservation function (S23). If the driving is reserved, the reservation time set in the driving reservation function is calculated backward, and the reservation time is determined. It is determined whether or not the rice washing time (time to start washing) has already elapsed from the current time (washing end time) (S24). When the rice washing time is too far from the current time, the various devices are immediately shifted to the rice washing operation and the rice washing operation is started (S25). If the rice washing start time has not passed, the rice cooker is put on standby in the state before the washing operation.

  According to the present invention, in the washing mode, the rice washing operation determination step S2 for determining whether or not the rice washing operation by the rice washing tank 12 is performed, and the water supply unit 15 is operated when the rice washing operation is not performed. From the water supply storage process S9 to S12 for storing water in the rice washing tank 12 and the drainage process S16 for flowing the water stored in the rice washing tank 12 by operating the opening / closing member 35 from the closed state to the open state. The water stored in the rice washing tank 12 in the water supply storage step can be flowed to the drainage box 14 at once, and the path from the drainage jacket 13 to the drainage box 14 can be washed with the momentum of water. That is, the water in the rice washing tank 20 passes through the drainage jacket 13, passes through the hole of the funnel member 31, flows into the pipe 34, and flows into the drainage box 14 together with the deposits attached to the funnel member 31. It flows from the mouth 47 to the outside.
