For example, the actual operation number may be counted based on the time point at which the cleaning cycle is set, or the time point at which the operation number is set. The number of days may be counted as a reference.
Further, in the above-described example, the cleaning display when the actual operation number matches the preset number of operations and the cleaning display when the number of days reaches the cleaning cycle are different, as shown in FIG. As such, these cleaning indications may be the same.

  In more detail, the cleaning display command unit 87, when the actual operation number is not the number of operations set by the cleaning display setting unit 85, when the cleaning cycle set in the cleaning cycle setting unit 86 is reached, You may comprise so that a cleaning display may be performed. That is, the cleaning display command unit 87 always displays the cleaning when the actual operation number reaches the number of operations set by the cleaning display setting unit 85, but the actual operation number is set by the cleaning display setting unit 85. Even if the number of operations has not been reached, the cleaning display may be displayed on the display unit if the cleaning cycle is reached. FIG. 11 shows the operation of the control unit 16 in the cleaning display.

In the following description, it is assumed that the number of operations for cleaning display is set for each cleaning location, and for the convenience of explanation, the actual operation count is counted from the time when the number of operations is set for each cleaning location. To do. In addition, the control unit performs the operation shown in FIG. 11 for each cleaning place, but for convenience of explanation, one cleaning place (for example, the rice washing tank 20) will be described as an example.
First, the control part 16 reads the cleaning period of the cleaning location (rice washing tank) set by the cleaning period setting part 86 (S1). Moreover, the frequency | count of operation of the rice washing tank 20 set by the cleaning display setting part 85 is read (S2).

And the control part 16 counts up the actual driving | operation number of the rice washing tank 20 whenever it repeats driving | operation of the rice washing apparatus 3, for example, every time driving | operation complete | finishes the actual driving | running number reaches the frequency | count of driving | operation. It is determined whether or not (S3). When the actual number of operations reaches the number of operations in the rice washing tank 20 (S3, Yes), the cleaning display command unit 87 performs a cleaning display for prompting the cleaning display for the rice washing tank 20 after the operation is completed (S4). For example, when the number of actual operations of the rice washing tank 20 reaches 300 times, when the operation is completed, the display unit 70 displays that the cleaning time of the rice washing tank 20 has come. At this time, the input of the cancel key 75 is accepted by the control of the control unit, but the input is not accepted for the other keys. Unless the cancel key 75 is pressed, the process of the display unit 70 or the process of the rice washing apparatus 3 is performed. Do not advance. When the cancel key 75 is pressed, the actual number of operations at the cleaning location displayed on the display unit 70 is reset to zero, and the display on the display unit 70 is switched from the cleaning display to the menu set screen B or the like. become able to.

  When the actual number of operations in the rice washing tank 20 has not reached the number of operations (S3, Yes), it is determined whether or not the rice washing tank 20 has reached the cleaning cycle (S5). For example, in the process of S5, when the number of days counted after setting the cleaning cycle or the number of operations of the rice washing tank 20 reaches the cleaning cycle (30 days) of the rice washing tank 20, the rice washing tank 20 is in the cleaning cycle. Judge that there is. When the rice washing tank 20 is in the cleaning cycle (S5, Yes), as described above, the cleaning display commanding unit 87 performs the cleaning display for prompting the cleaning display for the rice washing tank 20 after the operation is completed. The processing from S1 to S5 described above is not limited to the rice washing tank 20, but is similarly performed for other cleaning locations (the drainage jacket 13, the drainage hose, the water supply stiffness network 56, and the intake port 17).

Now, with regard to the determination of whether or not the cleaning part has reached the cleaning cycle, in the above description, the number of days after setting the cleaning cycle or the number of operations is counted, and the number of days is used. The number of modes may be used to determine whether the cleaning location has been achieved during the cleaning cycle. Since this cleaning mode automatically cleans the rice washing apparatus 3 once a day, it can be used to determine the cleaning cycle by counting the number of times the cleaning is automatically performed in the cleaning mode. .
First, the cleaning mode will be described.

  The cleaning mode is provided in the control unit 16. In the cleaning mode, at least the path from the drain jacket 13 to the drain box 14 can be cleaned. This washing mode is operated by a program incorporated in the control unit 16 and the like, and when the rice washing process is not performed (after the rice is weighed by the weighing unit 9, the weighed rice is put into the rice washing tank 20). When the introduced rice is not washed in the rice washing tank 20), the water is stored in the rice washing tank 20, and the water collected in the rice washing tank 20 is drained from the drainage jacket 13 through the pipe 34 at once. The water supply unit 15, the opening / closing member 35, and the like are controlled so as to be able to flow to 14.

This cleaning mode includes an automatic cleaning function for setting whether or not to perform the above-described cleaning automatically, and for automatically setting a scheduled time for cleaning when cleaning is automatically performed. ing. FIG. 12 shows the automatic cleaning function.
As shown in FIG. 12, in the automatic cleaning function, by pressing the auxiliary function key 80, the auxiliary function screen C is displayed on the display unit 70, and the menu for automatic cleaning of the auxiliary function screen C is selected by a cursor or the like. Can be used. When this automatic cleaning menu is selected, on the auxiliary function screen C, “valid” for enabling automatic cleaning, “invalid” for disabling automatic cleaning, and the time for automatic cleaning (reserving the time for cleaning) "Setting" for setting the cleaning reservation function) is displayed.

Here, automatic cleaning is enabled when "Enable" for enabling automatic cleaning is selected and determined with a cursor, etc., and automatic cleaning is disabled when "Invalid" for disabling automatic cleaning is selected and determined with a cursor, etc. It becomes. In addition, when using the frequency | count which performed automatic washing | cleaning for a cleaning period, naturally automatic washing | cleaning becomes effective and it is preferable not to select invalidity by control of the control part 16. FIG.
Then, by selecting and determining “setting” for setting the automatic cleaning time with a cursor or the like (by pressing the start key according to the cursor setting), the auxiliary function screen C sets the automatic cleaning reserved time. To the screen for automatic cleaning (automatic cleaning time setting screen). On the automatic cleaning time setting screen, “hour” and “minute” indicating the reservation time are displayed, and the numerical value corresponding to “hour” is changed by moving the cursor to the numerical value corresponding to “hour” and pressing a key or the like. In addition, the numerical value corresponding to “minute” is changed by moving the cursor to the numerical value corresponding to “minute” and pressing a key or the like. Thereby, it is possible to reserve a time for cleaning.

  The cursor can be moved by using the up key 76, the down key 77, etc. as shown in FIG. In addition to the cleaning mode, the control unit 16 is provided with an operation reservation function for making an operation reservation. This operation reservation function sets the time when rice is cooked in the rice cooker 1. Specifically, as shown in FIG. 13, the time reservation by the driving reservation function is performed by, for example, a reservation screen displayed by pressing the reservation key 74. In the driving reservation function, for example, reservation dates for four “Today”, “Tomorrow”, “Day after tomorrow”, and “3 days after” can be set. In the driving reservation function, by pressing the up key 76, the down key 77, etc., it is possible to switch between setting of “hour” and setting of “minute”, and setting of numerical values in “hour” and “minute” (time) Is set by pressing the left key 78, the right key 79, etc., and changing the numerical value.

In the driving reservation function shown in FIG. 13, the rice cooking time is set. However, by setting the rice cooking time by the driving reservation function, the control unit 16 starts washing the rice. The time to start (rice washing start time) is automatically calculated. In addition, in the driving reservation function, when the cooking time exceeds the current time, guidance is provided for how much time is required until cooking.
FIG. 14 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 S10). That is, in the time determination step S10, it is determined whether or not the current time is the reservation time set by the cleaning reservation function (automatic cleaning function). When the current time is the reserved time, it is determined whether or not the rice washing operation of the rice by the rice washing tank 12 is performed (rice washing operation determination step S11). In the rice washing operation determination step S11, 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. (S11, 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 performed (S11, 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 (S11, No), and if it can be determined that the rice washing operation is not being performed (S11, Yes), the process proceeds to the next.
In the washing mode, when the rice washing operation is not performed (rice washing operation determination step S11, Yes), it is determined whether or not the operation is reserved by the operation reservation function (operation reservation determination step S12). 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 S13).

  Here, when the reservation time in the cleaning reservation function matches the rice cleaning time in the operation reservation function (reservation time determination step S13, 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. In addition, after the rice washing operation is completed, even if the scheduled time for automatic washing has passed, automatic washing should be performed once a day in consideration of the period (time period) when the rice washing operation is not performed. It has become.

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, the display unit displays that the tank is being washed). 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 (S15), 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) (S16). 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 (inactive memory) provided in the control unit 16 (S17), the water supply unit 15 Is opened and water is supplied from the water supply nozzle 51 to the rice washing tank 20 (S18). 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 after starting water supply by the water supply nozzle 51 has reached a preset water supply amount (water supply determination step S19). 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 (S20). If the actual water supply time has not reached the planned water supply time, the process returns to the water supply amount determination step S19. 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 (S21).

By the process of step 17 (S17)-step 21 (S21), the process which stores 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) (S22), and the stirring drive device 50 is driven by the command signal to rotate the stirring member 21 (stirring washing step S23). 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 preset scheduled driving time (for example, 10 seconds) has been reached (S24).

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 S25).
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) (S26). ). 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. (S27).

A display indicating that the cleaning is completed is displayed on the display unit 70 of the display device 11 (for example, display of cleaning completion on the display unit S28). 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 (S29). The sound generation by the notification unit 81 is performed for a predetermined time (for example, 5 seconds, S30). 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 (S31).

  When the cleaning is completed, it is determined whether or not the driving is reserved by the driving reservation function (S32). If the driving is reserved, the reservation time set in the driving reservation function is calculated in reverse and the reservation time is determined. It is determined whether or not the rice washing time (time when rice washing is started) calculated from the above has already elapsed from the current time (washing end time) (S33). 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 (S34). If the rice washing start time has not passed, the rice cooker is put on standby in the state before the washing operation.

As described above, in the cleaning mode, cleaning is performed at least once a day according to the scheduled time for automatic cleaning.
Therefore, the control unit 16 may count the number of times automatic cleaning has been performed, and display a cleaning display when the number of automatic cleanings reaches the cleaning cycle at each cleaning location. That is, in the operation of the control unit 16 in the cleaning display shown in FIG. 11, when the number of days of automatic cleaning reaches the cleaning cycle (30 days) of the rice washing tank 20, it is determined that the rice washing tank 20 is in the cleaning cycle. Then, the cleaning indication of the rice washing tank 20 may be performed.

  According to the present invention, the cleaning display setting unit 85 that sets the number of operations for performing a cleaning display that prompts cleaning with respect to the cleaning site, the cleaning cycle setting unit 86 that sets the cleaning cycle of the cleaning site, and the actual operation When the number reaches the number of operations set by the cleaning display setting unit, or when the cleaning cycle set in the cleaning cycle setting unit 86 is reached, a cleaning display command unit 87 for performing a cleaning display on the cleaning portion is provided. I have. Thereby, according to the frequency | count of operation (the number of actual driving | operations) of the rice-washing apparatus 3, the location which needs cleaning can be automatically notified, and it can prevent forgetting the cleaning of a cleaning location. Moreover, since the frequency | count of a driving | operation for performing a cleaning display in a cleaning location is determined suitably, the cleaning display according to the dirt condition of the cleaning location can be performed.

  The cleaning display command unit 87 displays a cleaning display when the cleaning cycle set in the cleaning cycle setting unit 86 is reached even when the actual number of operations is not the number of operations set by the cleaning display setting unit 85. It has become. Thereby, even if the actual number of operations does not reach the number of operations, if the number of days has elapsed, the cleaning display at the cleaning location can be performed. That is, even if the number of actual operations per day is small and the number of days elapses, the cleaning location may become dirty, so if the cleaning display is performed when the cleaning cycle is reached, this situation Even under, cleaning of the cleaning part can be promoted, and the cleaning part can be kept clean.

FIG. 15 shows a modification of the operation of the control unit 16 in the cleaning display.
In the above description, the cleaning display is performed when the actual operation number has reached the number of operations at the cleaning location (rice washing tank) or when the cleaning cycle has been reached at the cleaning location (rice washing tank). In the modification shown in FIG. 14, even if the actual number of operations has reached the number of operations at the cleaning location (rice washing tank), the number of days since the start of the actual operation count is compared to the cleaning cycle. When it is larger, it is intended to omit the cleaning indication of the cleaning portion at least once.

In the modification of FIG. 15, automatic cleaning is effective, and it is preferable to perform automatic cleaning at least once a day. Moreover, in a modification, the means (washing | cleaning means) which wash | cleans cleaning parts, such as the rice washing tank 20 mentioned above, the drainage jacket 13, and a drainage hose shall be comprised.
As shown in FIG. 15, the control part 16 reads the cleaning period of the cleaning location (rice washing tank) set by the cleaning period setting part 86 (S40). Moreover, the frequency | count of operation of the rice washing tank 20 set by the cleaning display setting part 85 is read (S41).

And the control part 16 counts up the actual driving | operation number of the rice washing tank 20 whenever it repeats driving | operation of the rice washing apparatus 3, for example, every time driving | operation complete | finishes the actual driving | running number reaches the frequency | count of driving | operation. It is determined whether or not (S42). When the actual number of operations reaches the number of operations in the rice washing tank (S42, Yes), the number of days (elapsed days) from the start of counting the actual number of operations is read (S43). In S42, the number of days since the last cleaning display in the rice washing tank 20 may be set as the elapsed days.
And the control part 16 determines whether the elapsed days are larger than the cleaning period of the rice washing tank set by the cleaning period setting part 86 (S44). If the elapsed days are longer than the cleaning cycle (S44, Yes), the control unit 16 determines whether or not a flag indicating that the cleaning display is omitted is stored (S45). If the flag indicating that the cleaning display is omitted is not stored (S45, No), the control unit 16 resets the actual operation number in the rice washing tank 20 to zero (S46), and stores the flag indicating that the cleaning display is omitted. (S47). And the process in the control part 16 returns to S42.

As described above, even when the actual number of operations reaches the number of operations in the rice washing tank, if the elapsed days are longer than the cleaning cycle, the cleaning display processing does not proceed as can be understood from the processing of S45 to S47. The cleaning indication is omitted.
That is, even when the actual operation number reaches the number of operations set by the cleaning display setting unit 85 by the control of the control unit 16 as shown in FIG. If it is longer than the period, the cleaning display is omitted at least once.
On the other hand, when the flag indicating that the cleaning display is omitted is stored and the cleaning display is omitted once (S45, Yes), the control unit 16 deletes the flag indicating that the cleaning display is omitted (S48). ), A cleaning display in the rice washing tank 20 is performed (S49).

According to this modification, the cleaning means for automatically cleaning the cleaning portion is provided, and the cleaning display command unit 87 is configured such that when the actual operation number reaches the number of operations set by the cleaning display setting unit 85, When the number of days since the start of the actual operation count is longer than the cleaning cycle, the cleaning display is omitted. According to this, since the cleaning portion is automatically washed, even if the elapsed days have passed from the cleaning cycle, the cleaning portion is kept clean by automatic washing. Can omit the cleaning indication. That is, when a lot of automatic cleaning is performed for the actual number of operations per day, the cleaning points such as the rice washing tank 20, the drainage jacket 13, and the drainage hose related to this automatic cleaning and cleaning means are Because the times are washed and clean, these cleaning cycles can be extended,
The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
