Under the control of the mechanism section, the rice to be cooked is measured, and the washed rice and a predetermined amount of water are automatically put into the rice cooking pot, and the rice is placed between the fully automatic rice cooking device main body 1 and the automatic rice cooker 7. Data communication is performed, and control data for the amount of rice that has been weighed is input, as well as control data for specifying the start of rice cooking, and the rice cooking operation is started. In this case, the number of rice-cooking heaters is not determined during the rice-cooking control, and the heating power of the rice-cooking heaters is controlled in accordance with the amount of rice cooked according to the control data received from the fully automatic rice-cooking apparatus main body 1 through data communication.

FIG. 6 is a flowchart showing an outline of the rice cooking control flow of the rice cooking control circuit 60. This will be explained with reference to FIG.

When the rice cooking control circuit 60 of the automatic rice cooker 7 is powered on, the microcomputer of the rice cooking control section 61 of the rice cooking control circuit 60 performs initialization processing such as initial reset.
In step 70, it is determined whether the system is fully automatic. That is, it is determined whether the rice cooking control is performed in the first rice cooking control mode (not fully automatic) or the rice cooking control (fully automatic) in the second rice cooking control mode. If it is not determined in step 70 that the rice cooking is fully automatic, the automatic rice cooker 7 waits for a rice cooking start instruction from the rice cooking start switch from the display input section 66 of the rice cooking control circuit 60, so the process advances to step 71 and the rice cooking start switch is turned on. It is determined whether or not. If it is not determined in step 71 that the rice cooking start switch is on, the process returns to step 70 and repeats the process from step 70.

If it is determined in step 70 that the rice cooker is fully automatic, the process proceeds to step 72, where the control data received through data communication from the main body control circuit 50 of the main body 1 of the fully automatic rice cooker g is stored, and the next In step 73, the fully automatic memory indicating the second rice cooking control mode is set, and the process proceeds to step 74. In addition, in step 70, it is determined that the rice cooking device is fully automatic when control data is received from the main body control circuit 50 of the fully automatic rice cooking device main body 1, and upon receiving the control data, it is determined that the rice cooking device is fully automatic. .

In the next step 74, a water absorption process is performed.

The water absorption process is a process in which the water in the rice cooker is heated and the rice is sufficiently absorbed. Next, in step 75, it is determined whether 500 seconds have elapsed in order to determine the end of the water absorption process. In step 75, 500
Until the second is determined, the process returns to step 74 and the water absorption process of step 74 is repeated.

When 500 seconds have elapsed and the water absorption process has been completed, the process proceeds to the next step 76, where the rice cooking heater is turned on and the temperature is raised to T O 0 C, which is the reference temperature for determining the rice cooking capacity. This T
It is determined in step 77 whether the temperature has reached 0°C. If it is determined in step 77 that the temperature is below To° C., the process returns to step 76 to continue turning on the rice cooking heater.

If it is determined in step 77 that To° C. has been exceeded, it is determined in step 78 whether or not fully automatic memory (set) is set. If it is not a fully automatic memory, it is the first rice cooking control mode, and the rice cooking capacity is determined in this automatic rice cooker 7, so the process proceeds to step 80, after performing the process of determining the number of rice cookers and obtaining data on the rice cooking capacity. , 100
Cook until the temperature reaches ℃. Then, the process proceeds to the next step 82, and in the process from step 82, heating power is determined according to the rice cooking capacity and processing is performed to continue boiling with the optimum heating power.

Further, if it is determined in step 77 that the temperature exceeds To°C, and furthermore, it is determined in step 78 that it is fully automatic memory, this means that the second Since this is the rice cooking control mode, there is no need to determine the rice cooking capacity in this case. Therefore, the process proceeds to step 79, where the reference temperature for temperature determination is set to 100° C., and cooking is performed without determining the number of units. That is, in step 79, if the temperature is below 100° C., the process returns to step 76 and continues turning on the rice cooking heater.

In this case, the rice cooking heater continues to be turned on in a loop of step 76→step 77→step 78→step 79→step 76. In step 79, 100°C
If it is determined that the value exceeds 1, the process proceeds to step 81, where fully automatic memory data conversion processing is performed. This uses the control data sent from the fully automatic rice cooker main unit 1.
It is converted into data in the same format as the data indicating the rice cooking capacity (for example, temperature rise time data according to heat capacity) obtained in the process of determining the number of rice cookers. And next step 8
Proceeding to step 2, in the processing from step 82, heating power is determined according to the rice cooking capacity, and processing is performed to continue boiling with the optimum heating power. That is, step 82. Step 83
．． Through the determination process in step 84, the ranges of rice cooking capacity data for which the number of rice cooking capacity has been determined are determined as a, b, c, and d, respectively, and according to the determined ranges a, b, c, and d, respectively in step 85. Step 86. Step 87. In step 88, each corresponding rice cooking heater A
, rice-cooking heater B, rice-cooking heater C2 energization control of the rice-cooking heater is performed using the heating power of rice-cooking heater D, and heating control is performed to maintain boiling.

Such boiling heating control maintains boiling,
The boiling state of the rice cooker continues until the rice absorbs enough water and the water at the bottom of the rice cooker disappears, and the temperature of the rice cooker rapidly rises until it is determined that it has reached 130°C. That is, this means that in step 89, the temperature of the rice cooker is 1.
It is determined whether the temperature is 30° C. or lower, and while it is determined that the temperature is 130° C. or lower, the process returns to step 82 and the processing from step 82 is repeated. For example, in the process of determining the number of rice cookers or in the process of fully automatic memory data conversion, if the rice cooking capacity is determined to be within the range, this is determined in step 83, and in step 86, the rice cooking capacity is determined by the heating power of rice heater B. Electricity control is performed, and further, in step 89, it is determined whether the temperature is 130° C. or lower (=32-), and heating control is performed to maintain boiling. Until it is determined in step 89 that the temperature exceeds 130°C, the process continues in step 89 → step 82 → step 83 → step 86.
→The processing loop of step 89 is repeated. When it is determined in step 89 that 1308C has been exceeded,
Next, in step 9°, the unevenness process is performed,
In the next step 91, a heat retention process is performed and the process ends.

In addition, in the unevenness process of step 90, a first unevenness process, a first additional cooking process, a second unevenness process,
A second additional cooking process etc. is performed. And next step 91
This leads to the heat retention process. Normally, this process of keeping warm is continued until cancellation of keeping warm is instructed by an operation switch.

Next, the operation of the main body control circuit 50 on the side of the fully automatic rice cooking device main body 1 will be explained.

Figure 7a, Figure 7b, Figure 7c, Figure 7d, Figure 7e,
FIG. 7F is a flowchart 1- showing an outline of the rice cooking control flow of the main body control circuit 50.

M- First, please refer to Figure 7a. In step 101,
When the power is turned on, the current time is displayed in the next step 102. Next, in step 103, an initial reset is performed to reset the work registers and the like to perform initialization processing. Next, in step 104, it is determined whether the menu switch (menu SW) and the rice cooking switch (rice cooking Sw) are turned on at the same time. The determination process at step 104 is a process for determining whether or not to perform maintenance test program processing.

If the menu SW and rice cooking SW are turned on at the same time, the process proceeds to test program processing (105).

Since the test program processing is not directly related to the present invention, a description thereof will be omitted here.

If it is determined in step 104 that the menu SW and rice cooking SW are not turned on at the same time, the process proceeds to step 106, where it is determined whether or not there is an error pit. If there is an error pit, in step 107 error processing is performed according to the contents of the error pit, and the process returns to step 106 to determine whether or not there is an error pit. If it is determined that there is an error pit again, in step 107 error processing is performed again in accordance with the error pit. In this way, the presence of an error pit indicating the details of the error that has occurred here is sequentially determined (step 106).

Error processing (step 1o7) is performed accordingly.

After confirming that there are no error pits in step 106, the process proceeds to step 108, where it is determined whether the process counter has been cleared. If the process counter has not been cleared, the process advances to step 109, where a process counter search process is performed. This process counter destination search process is to compensate for power outages. After checking power outages, setting failures, etc., rice cooking Perform processing to continue process control or error handling. If the process counter destination search process subroutine in step 109 returns and ends, the process starts from step 106. In step 108, when clearing of the process counter is confirmed, next step 1 in FIG. 7b is performed.
Proceed to step 10.

See Figure 7b. Next, in step 110, process initial processing is performed. Processing of process initials is as follows.
This is a process for checking whether moving members such as a control motor and an actuator are located at the initial position (home position) in each mechanical part of the fully automatic rice cooker main body 1.

If each moving member is not located at its initial position,
In this process initial process, each moving member is driven to its initial position. Step 110
When the process initial is completed, the process proceeds to step 111, where a process is performed to determine whether or not there is an abnormality in the process initial. In the process of step 111, if it is determined that there is an abnormality in the process initial, the process returns to step 106.

Also, if there is no abnormality in the process initial, the next step 1
Proceeding to step 12, the rice cooker status is confirmed. Next, in step 113, it is determined whether the clock switch is turned on. Only when the clock switch is turned on, the current time is set in step 114. Perform the processing to set. Next, in step 115, it is determined whether the reservation switch is on.

If the reservation switch is not on, then in step 116 it is determined whether the menu switch is on, and if the menu switch is not on, then step 117 is performed.
Determine whether the heat retention switch is on. If the heat retention switch is not on, then step 122 is performed to confirm the power outage, and the process returns to step 110 to repeat the process from step 110 starting from the initial stage.

If it is determined in step 115 that the reservation switch is on, then in the next step 120 it is determined whether or not the pan is removed and the memory is set. If the pot is removed and the memory is set, the process advances to step 121 to issue an error notification, and the next step 122 performs power outage confirmation processing, and returns to step 110.

If the pan is removed and the memory is not set in step 120,
Once the rice cooker has been removed, it can be confirmed that the rice cooker has been properly cleaned. After confirming this, proceed to step 123.
In step 124, the amount of stored rice is checked, and in step 124, the amount of water is checked, and in step 125, it is determined whether or not there is an error. If there is an error, step 106 (7a)
Returning to FIG. 3, the process from step 106 is performed again. If there is no error in step 125, the previous course flashing process is performed in step 126, and step 146
Proceeding to (Fig. 7d), processing in the reservation rice cooking mode from step 146 is performed.

On the other hand, in the determination process of step 117, if it is determined that the keep-warm switch is on, the keep-warm switch is in progress (118;
The process proceeds to the process shown in FIG. 10).

Further, if the process proceeds to step 116 and it is determined that the reservation switch is not on but the menu switch is on, the process proceeds to step 119 and the fully automatic rice cooking control is performed not in the reservation mode but in the immediate operation mode. In order to perform this process, the process proceeds to a process for menu selection, which will be described later. That is, in step 119, it is determined whether or not the pan removed memory is set. If the pan removed memory is set, the process proceeds to step 121, where an error notification is performed, and in the next step 122, a power outage confirmation process is performed. , step 11
Return to 0. Also, if the pot removal memory is not set in step 1]-9, you can confirm that the rice cooker has been removed and the rice cooker has been properly cleaned.After confirming this, proceed to step 127. The amount of stored rice is checked, and further, in step 128, the amount of water is checked.

Next, in step 129, it is determined whether there is an error.

If there is an error, return to step 106 (Figure 7a);
The processing from step 106 is performed again. Step 129
If there is no error, the next step 130 (Figure 7c)
Proceed to.

Reference is now made to Figure 7c. When performing the process in the fully automatic rice cooking control mode of the immediate operation mode, the process from step 130 is performed. In step 130, the previous course blinking process is performed, in the next step 131, a power outage is confirmed, and further, in step 132, a course selection process is performed. This course selection process is a process of selecting a course of operation for each rice cooking process in fully automatic rice cooking control.

As is clear from Figure 3, the course selection process includes white rice, quick-cooked rice,
Choose from 5 types of menus: 1 cup of cooked rice, 1 cup of rice porridge, and 2 cups of rice porridge, and select the amount of cooked rice from 2 cups to 1 cup.
Select the amount of cooked rice for each cup up to 0 cups. In addition, if you install an optional rice polishing unit and polish brown rice to cook rice, you can set the polishing degree to white rice.

Choose from five options: 7 minutes, 5 minutes, 3 minutes, and brown rice. Select the degree of "hardness" of the cooked rice from "hard" to "soft" on a scale of 10. This "Kadasa" selection instruction provides instruction data for the amount of water when cooking rice. Furthermore, the degree of rice washing is set in three stages.

Returning again to FIG. 7C and continuing the explanation, step 13
When the process of course selection in step 2 is completed, the next step is step 13.
Perform the process for confirming set failure in step 3.

The setting failure confirmation process is a process of confirming whether the rice storage measuring unit, rice washing unit, rice cooking unit, automatic rice cooker of the rice cooking unit, etc. are set in normal positions. At step 133, when the set failure confirmation process is completed, the process proceeds to step 134, where it is determined whether or not the cancel switch has been turned on. If it is determined that the cancel switch is on, the process proceeds to step 135, where the course LED (course display light emitting diode) on the operation display panel is turned off, and then, in step 136, the process counter is set to (OO). Then, the process returns to step 106 to start the process from the beginning. If it is determined in step 136 that the cancel switch is not turned on, the process proceeds to step 137, in which it is determined whether or not there is a set failure. If there is a set failure here, the process returns to step 131 and processes from step 131 power failure confirmation are performed. If there is no set failure, it is determined in step 138 whether the reservation switch has been turned on. Here, if it is determined that the reservation switch is on, the operation is switched to the reservation rice cooking mode, so the process proceeds to step 146 to perform fully automatic rice cooking control processing in the reservation rice cooking mode.

If the reservation switch is not determined to be on in the determination process of step 138, then the process proceeds to step 139, where it is determined whether or not the start switch is turned on.

If the start switch is not determined to be on, step 1
Returning to step 31, the processes from step 131 to step 139 are repeated until the start switch is turned on. If it is determined in step 139 that the start switch is on, the process proceeds to the next step 14.0, where rice cooker communication processing is performed. The rice cooker communication process here is a process for confirming that the full-motion rice cooker 7 is set in the rice cooking unit 4. Next, in step 141, the gantry is locked, and in the next step 142, it is determined whether or not there is a lock abnormality. If it is determined in this determination that the pedestal lock is abnormal, the course LED on the operation display panel is turned off in step 143, and the process returns to step 106 to start the process from the beginning. If no lock abnormality is determined in step 142, the process proceeds to step 144, where the course data is stored, and in the next step 145, the course LED is turned on. Then, step 145 is followed by step 17 in FIG. 7e.
The process proceeds to step 2, and continues to the rice polishing process, rice weighing process, rice washing process, etc. from step 172.

On the other hand, continuing from step 126 of FIG. 7b or branching from the decision step of step 138 of FIG. 7c,
The process in the reservation rice cooking mode from step 146 in FIG. 7d continues.

Referring to FIG. 7d, first, step 146
, flash Reservation 1 or 2, then step 14
At step 7, the reserved time and the cooking completion indicator will blink. continue,
In step 148, a power outage is confirmed, in step 149, time is set, and in step 150, a course selection process is performed. Next, in step 151, a set failure is confirmed, and in the next step 152, reservation switching processing is performed. Next, in step 153, it is determined whether the cancellation switch has been turned on due to an error in the reservation settings, etc., and if the cancellation switch has been turned on, the process proceeds to step 154, where the flashing display is turned off and the next In step 155, set the process counter (
OO) and return to step 106 to perform processing from the beginning starting from the error check.

In addition, if the cancellation switch is not determined to be on in step 153 and the reservation time, course selection, etc. are set, then in step 156 it is determined whether or not there is a setting failure and the set contents are consistent. After confirming that it is valid, it is then determined in step 157 whether or not a start switch for starting the operation of the reservation rice cooking mode has been turned on.

If the start switch is turned on, then step 1
Step 58 compares the reserved time with the current time to check whether the set reserved times are consistent. If the reservation times are inconsistent, proceed to step 159;
Outputs a voice saying “Reservation is not possible” and steps 148
The process returns to step 148 and performs the reservation rice cooking mode setting process from step 148 again. The process of resetting the reservation rice cooking mode by returning to step 148 is as follows: If it is determined in step 156 that there is a Cerato malfunction, or if it is not determined that the start switch is on, the process returns to step 148 and the reservation Performs the rice cooking mode resetting process.

Further, if the reservation time is checked in step 158 and the reservation time is OK (appropriate), the process proceeds to step 160 to perform rice cooker communication processing. The rice cooker communication process here is a process for confirming that the full-motion rice cooker 7 is set in the rice cooking unit 4. Next, in step 161, processing for locking the pedestal is performed, and the next step 162
It is determined whether or not there is a lock abnormality. If this judgment determines that the pedestal lock is abnormal, step 1
In step 63, the flashing display is turned off and the process starts from the error check process, so step 10 is performed.
Return to 6. If no lock abnormality is determined in step 162, the process proceeds to step 164, where the course data is stored, and in the next step 165, the reserved time and cooking completion displays are turned on. Next, in step 166, the reservation LED and course LED are turned on. Then, in the next step 167, processing during the reservation timer (subroutine processing) is performed.

In the subroutine for processing during the reservation timer, the contents of the process counter are set to (02), which indicates that the reservation timer is in progress, and while checking the power outage, the current time is monitored to see if it is the reservation time, and the reservation time is set. Return when the time comes.

When the process during the reservation timer ends and the reservation time comes, the reservation LED, reservation time, and cooking completion display are turned off in step 168. Next, in step 169, it is determined whether or not the end of the reservation is due to the cancellation switch being turned on. If the reservation is being ended due to the cancellation switch being turned on, the process proceeds to step 170, where the course LED is turned off, and step 17
Step 10 sets the process counter to (00) and registers the process from the beginning from the error check.
Return to 6.

In addition, if it is confirmed in step 169 that the reservation is not terminated by turning on the cancel switch, then step 7e
The process advances to step 172 in the figure, and continues to the rice cooking preparation process from step 172, such as a rice polishing process, a rice measuring process, and a rice washing process.

With reference to FIG. 7e, the rice cooking preparation process performed subsequently before starting the rice cooking operation will be described.

First, in step 172, the display section shows "
The J LED is turned on during rice washing, and then, in step 173, the slide backward movement (03) process is performed, and in the next step 174, it is determined whether or not there was an error in the previous slide backward movement process. Next, in step 175, the lock cam operates (04).
In step 176, it is determined whether or not there is an error in the lock cam operation processing. Next step 17
At step 7, perform the lid opening step (05) and proceed to the next step 17.
In step 8, it is determined whether or not there was an error in the lid opening process. Subsequently, in step 179, lock cam storage (06) processing is performed, and in the next step 180, it is determined whether or not the lid has been opened normally based on the detection output of the lid opening sensor. If the lid opening operation is not performed normally, step 1
In step 81, the operation counter determines whether or not the lid opening operation is checked for the third time. If it is the third time or less, return to step 175,
Again, in the process starting from step 175, the lid is opened. Also, if the lid opening operation is checked in step 181, and the third check is passed, the lid opening/closing mechanism is determined to be abnormal, so the process proceeds to step 182, where the error bit (08) is set. Step 219 to be described later
Proceed to (Fig. 7f) and turn off the rice washing J LED and end the rice washing process with an error. Similarly to the process flow from step 182, when the rice washing process is terminated due to an error, it may be determined that there is an error in step 174, step 176, and step 178. In this case as well, the process similarly proceeds to step 219 where the message ``Rice Washing J'' is turned off and the process of the rice washing process is ended in error.

On the other hand, if it is determined in step 180 that the lid opening operation was performed normally, the process proceeds to step 183;
Determine whether a rice milling unit is installed. If it is determined that a rice milling unit that can be installed freely is installed, in this case, the rice milling process is controlled, so the process proceeds to step 184, and in step 184, the rice milling process (06) is started.
Process. If it is determined in step 183 that no rice milling unit is installed, there is no need to perform the rice milling process, and the process proceeds directly to the next step 192.
Proceed to.

In step 192, confirm that there are no errors,
In the next step 193, a slide advance (07) process is performed. In step 194, it is determined whether or not there was an error in the processing of the slide city road. Next, step 19
5 is a measuring step (08) in which the amount of rice to be cooked is measured.
In step 196, it is determined whether or not there was an error in the weighing process. These error determination steps 192. Step 194. If it is determined in step 196 that there is an error, the “Rice Washing
The LED is turned off and the process proceeds to step 219 (FIG. 7f) in which the rice washing process is terminated due to an error.

As a result, in the rice cooking unit 4, the automatic rice cooker 7 placed on the trolley on the slide rail moves backward, the lid of the automatic rice cooker 7 is opened by the lid opening/closing mechanism 40, and the rice cooker 7 moves forward again to weigh and wash the rice. It will be in a position where it will receive the rice that has been washed. Subsequently, the rice to be cooked is measured in the rice storage and measuring unit 2, and the rice is placed in the rice washing device 30 of the rice washing unit 3. Subsequently, the rice washing device 30 is controlled to wash the rice.

To control the rice washing device 30, first, in step 197, the rice washing device 30 is
Step (o9) is carried out, and in step 198, the polishing rice step 1 (O
Perform A), then step 199 for rice washing step 2 (OB)
Then, in step 200, a second rice polishing process (OC) is performed.

Next, in step 201, a third rice washing step (09) is performed. Next, in step 202, overflow (OE) processing is performed to complete the washing rice processing, and then the next step 203
The waste water process (OF) is carried out at When the rice washing process is completed through this series of processes, the next step is step 20 in FIG. 7f.
Proceed to the rice removal process in step 4.

Continuing the explanation with reference to Figure 7f, next step 20
In step 4, the rice discharging process (10) is performed, and in the next step 205, it is determined whether or not there was an error in the previous slide backward movement process. Next, in step 206, a water adjustment step (11) is performed, and in step 207, it is determined whether or not there was an error in the water adjustment step. Next, in step 208, tank cleaning (12) is performed, and in the next step 209, it is determined whether or not there was an error in the tank cleaning process. Furthermore, in the next step 210, the slide moves backward (1
3) is performed, and in step 211 it is determined whether there is an error. Next, in step 212, the lid closing step (1
4) is performed, and then in step 213, the state of the automatic rice cooker is detected by the lid sensor, and it is determined whether or not the lid is in the closed state. If the lid is not closed, the process proceeds to step 214, where it is determined by the operation counter whether this is the third time the lid opening operation has been checked. If it is the third time or less, the process returns to step 212, the lid closing step of step 212 is performed again, and the lid closed state is checked in the next step 213. If it is determined in step 214 that the lid closed state check in step 213 has exceeded the third check, the process proceeds to step 215, where an error pit (11) to display the error in this case is set, and step 219 The process proceeds to ``Rice Washing J'' and turns off the LED to terminate the rice washing process due to an error.Then, the process returns to step 106 to perform the process from the beginning from the error check.

Furthermore, if the lid is closed in step 213, the process advances to step 216, where it is determined again whether or not there is an error, and then in step 217, the slide moves forward (15).
Process. Then, in the next step 218, it is determined whether or not there was an error in the slide advance processing. If it is determined in step 218 that there is an error, then the process proceeds to step 219, where [the JLED during rice washing is turned off, the processing during the rice washing process is terminated with an error, and the process starts from the beginning from the error check]. To do so, return to step 106. On the other hand, if it is determined in step 218 that there is no error, the process proceeds to step 220, and [Rice Washing J L
The ED is turned off, the rice washing process is completed, and the next rice cooking process is started.

Through such control processing, after the rice is washed by the rice washing device 3o, the washed rice is stored in the automatic rice cooker 7, which is located at the bottom of the rice washing device 30 with the lid opened, and is heated to a predetermined level. Add enough water to adjust the water level. Next, the automatic rice cooker 7 is moved backward, the lid of the automatic rice cooker 7 is closed by the lid opening/closing mechanism 40, and the automatic rice cooker 7 is moved forward again and positioned at a predetermined position for rice cooking so that the steam generated during rice cooking can be discharged. Then, the rice cooking preparation process is completed.

When the rice cooking preparation process is completed in the control process up to step 220, the rice cooking process from step 221 is then performed.

In the subsequent rice cooking process, first step 22
In step 1, it is determined whether the menu is seasoned rice. When the rice is ready to be cooked, the rice cooking control operation is temporarily interrupted in order to put the ingredients to be cooked into the rice cooking pot of the automatic rice cooker 7. Therefore, in step 222, a process of blinking the "Rice cooking J" LED is performed, and in the next step 223, a process of waiting for restart (16) is performed.

In the restart waiting processing subroutine, the contents of the process counter are changed to indicate that the restart waiting processing is in progress (
16) and performs a process of generating a buzzer sound to alert the user at predetermined time intervals while checking for power outages and setting failures. During this process, it is monitored whether the start switch is turned on or not, and when the start switch is turned on, a set failure is checked again and the process returns.

The process of waiting for restart (16) in step 223 is performed, and in this process, the rice cooking control operation is temporarily suspended, and while the user is waiting for the start switch to be turned on again, the user can add the ingredients to be cooked with the cooked rice. When you put the rice into the rice cooker and turn on the start switch, this step 22
The process exits from the restart waiting process in step 3 and proceeds to step 224. In addition, if the rice is not determined to be cooked rice in the process of determining whether it is cooked rice in the previous step 221, then step 22
Proceed to step 4.

In the process of step 224, the ``Rice Cooking J'' LED is turned on to indicate that the rice cooking process has started, and in Step 225, the rice cooking process (17) is performed.

The process during rice cooking (17) will be described later, but communicates with the rice cooker, sends an instruction to start cooking to the automatic rice cooker 7, starts the rice cooking operation, and controls the exhaust fan during this time. The water vapor generated from the automatic rice cooker 7 during the rice cooking operation is exhausted, the time is monitored, and the time until the rice cooking operation is completed and the rice becomes ready for eating is displayed.

When the rice-cooking process in step 225 is completed, the rice-cooking J LED is turned off in step 226 to indicate that the rice-cooking process has finished, and in the next step 227, the rice-cooking LED is turned off. Determine whether there is an error in processing. If it is determined that there is an error, step 106 is performed to perform the process from the beginning starting from the error check.
Return to Further, if it is not determined that there is an error, the process of keeping warm (18) in the next step 228 is performed.

The process during keeping warm (18) in step 228 will be described later, but it is continued while the automatic rice cooker 7 is keeping warm, and during this time, the exhaust fan is controlled to be driven intermittently. When the warming process is terminated due to turning on the cancel switch or the occurrence of an error, the process returns to step 106 to start the process from the beginning.

In the main routine of the control processing flow of the fully automatic rice cooker main body, typical subroutine processing for control processing for each mechanical section and individual processing of each step will be described below.

FIGS. 8a and 8b are flowcharts showing a subroutine process for checking a set failure. This set failure confirmation process is frequently performed in the main routine of the control processing flow of the fully automatic rice cooker main body, and the set state of each unit of the mechanical section in the fully automatic rice cooker main body 1 is confirmed. The results of the confirmation process performed in the set defect confirmation process are displayed on the rice cooking element device set display section 18 in one display zone on the operation display panel 5, showing the symbols of the fully automatic rice cooker main body and each device unit. is schematically displayed by each set confirmation display LED provided corresponding to the set position of the symbol of each device unit on the display section. From this, it is easy to determine the type of each device unit that is set incorrectly.

With reference to FIGS. 8a and 8b, the process of confirming a set failure will be described. In this process, a set of automatic rice cookers,
Check the rice cooker rail setting position and the rice storage storage setting position for setting defects.

First, in order to check the state of the automatic rice cooker set, in step 301, it is determined whether rice cooker communication is performed normally. In the determination in step 301, 5. When it is determined that the rice cooker communication is normally performed between the fully automatic rice cooker main body and the automatic rice cooker, the automatic rice cooker 7 is set in the rice cooking unit 4, and the power plug of the automatic rice cooker 7 is also connected. It is determined that the device is plugged into an outlet and is electrically operable. In step 301, rice cooker communication is turned off.
If it is K, the set state of the inner pot can be determined by the sensor of the automatic rice cooker 7 depending on the contents of the rice cooker communication, so first, in step 302, it is determined whether or not there is an inner pot. If there is an inner pot, it can be determined that the automatic rice cooker 7 of the rice cooking unit 4 is set normally, so step 305
In step 302, the Passet defective position display LED corresponding to the display position of the automatic rice cooker is turned off.
If it is not determined that there is an inner pot, the process proceeds to step 303, where the 6 set failure LED blinks, and then in step 304, the ``set failure position display'' LED corresponding to the display position of the automatic rice cooker is turned on. flashes.

Next, check if the rice cooker rail is set in the wrong position. Therefore, in step 306, it is determined whether the rice cooker rail set position is OK (normal position).

If the rice cooker rail set position is OK, step 30
Proceed to step 9, and turn off the "setting defective position display" LED corresponding to the display position of the rice cooker rail set position. In addition, if it is not determined in step 306 that the rice cooker rail set position is OK, the process proceeds to step 307, and
The "set failure" LED is blinked, and then in step 308, the "set failure position display" LED corresponding to the display position of the rice cooker rail set position is blinked.

Next, check for a setting failure at the rice storage setting position. Therefore, in step 310, it is determined whether the rice storage set position is OK (normal position). If the rice storage set position is OK, the process proceeds to step 313, and the "defective setting position display" LED corresponding to the display position of the rice storage set position is turned off. In addition, if it is not determined in step 310 that the rice storage set position is OK, the process proceeds to step 311, where the "1 set defective" LED blinks, and then in step 312, the rice storage set position is displayed at the display position. The corresponding "defective set position display" LED blinks.

As a result, we were able to confirm that each of the individual positions of the automatic rice cooker, the rice cooker rail set position, and the rice storage storage set had a setting failure, so we set a flag indicating that there was a setting failure in the overall sense. Therefore, in step 314, it is determined whether all the "setting defective position display" LEDs are turned off. If all the "setting defective position display" LEDs are not turned off, step 315
Proceed to , set the "r set defect" flag, and return to the main routine. In addition, if all the "defective set position display" LEDs have not turned off, the process advances to step 316, where the "defective set" flag is reset, and in the next step 317, the "9 defective set" LEDs are turned off.
Turn off the light and return to the main routine.

FIG. 9 is a flowchart showing the subroutine processing of the rice cooking process. In the rice cooking process carried out on the side of the fully automatic rice cooker -61-m-6〇-, rice cooker communication is performed, and an instruction to start cooking is sent to the automatic rice cooker 7 to start the rice cooking operation. During this time, the exhaust fan is controlled to exhaust the steam generated from the automatic rice cooker 7 during the rice cooking operation, and the time is also monitored to display the time until the rice cooking operation is finished and the rice is ready to eat. I do.

First, in this process, a process counter is set to (17) in step 401 to indicate that rice is being cooked. Next, in step 4.02, processing for locking the pedestal is performed, and then in step 403, it is determined whether or not there is an abnormality in the pedestal lock. If there is an abnormality in the pedestal lock, the process immediately returns to the main routine. In this case, it is not a normal return but an abnormal return, and as a result, in the main routine, as mentioned above, the process of the rice cooking process is completed, so the "Rice Cooking" LED indicating the end of the rice cooking process is turned off. 226), then it is determined that there is an error (step 227), and the process starts from the error check process from the beginning (returns to step 106).

In addition, in the determination in step 403, if it is determined that there is no gantry lock abnormality, in the next step 404,
A rice cooking start communication is performed to start the rice cooking operation in the automatic rice cooker 7. As a result, in the automatic rice cooker 7,
The rice cooking control process is started according to the rice cooking control process flow shown in FIG. In a fully automatic rice cooker, step 40
After checking the rice cooking start communication in step 4, the next step is 405.
After performing the power failure confirmation process in step 406, it is determined whether the rice cooker communication of the rice cooking start communication performed in step 406 is OK. If there is no reception response in the rice cooker communication and the rice cooker communication is not OK, it is determined in the next step 407 whether or not the time is up, and if the time is not up,
Returning to step 405, the processing for confirming power outage and the determination processing for confirming rice cooker communication are repeated. If a predetermined time-up period elapses, there is no reception response to the rice cooker communication, and the rice cooker communication is not determined to be OK, and a time-up occurs in step 407, the process proceeds to step 408, where an error state is indicated. Therefore, set an error pit (E12).

Then, the "minutes left" display is turned off and the process returns to the main routine.

In this case as well, it is not a normal return but an abnormal return, so
As a result, in the main routine, as described above, the processing of the rice cooking process is completed, so the "Turn off the rice cooking J LED" step 226 indicating the end of the rice cooking process is performed.
, then determines that there is an error (step 227).
, the process starts from the beginning with the error check process (returns to step 106).

Further, in step 406, if there is a reception response for the rice cooker communication within a predetermined time-up period and it is determined that the rice cooker communication is OK, the automatic rice cooker 7 has started the normal rice cooking control operation. In the next step 410, the exhaust motor is turned on and the exhaust fan unit is driven to start exhausting the steam generated from the automatic rice cooker 7.

Next, in step 411, power outage confirmation processing is performed.

In the next step 412, the rice is cooked -ba
- In order to determine whether or not the cooking time display section is displaying "minutes left to cook" or not. If the "cooked rice" display is not displayed to indicate when the rice is cooked, the process proceeds to step 413, where it is determined whether the rice cooking menu is for cooking, and if it is for cooking, the process proceeds to step 41.
In step 4, it is determined whether or not it is an uneven process. When the rice cooking menu is "cooking" and the rice cooking process is started, the process advances to step 415, where the "minutes left" display is turned on, and then the process returns to step 411, and the process from step 411 is repeated. Furthermore, if it is not determined in step 413 that the process is to be cooked, and also if it is not determined to be the shading process in step 414, the process returns to step 411 and the processes from step 411 are repeated.

When the rice is cooked and it is determined in step 412 that the cooking time display section is showing "more juxtaposition", the process proceeds to step 416, and the "□ minutes left" display is turned off. Next, in step 417, the buzzer notification 3 is processed, and then, in step 418 of Figure 1, it is determined whether the loop counter has reached 8 times or not. The process of confirming and returning to step 417 is repeated. As a result, the process of buzzer notification 3 is repeated eight times to notify that the cooking is finished, and then the process returns to the main routine. In this case, it is a normal return.

FIG. 10 is a flowchart showing the processing flow of the subroutine of the warming process. This warming process performed on the side of the fully automatic rice cooker will ensure that the rice cooking process is performed normally.
This process is performed in response to the completion of the rice cooking operation of the automatic rice cooker 7 and the automatic rice cooker 7 entering the warming operation. This heat keeping process continues while the automatic rice cooker 7 is keeping warm, and during this time the exhaust fan is controlled to be driven intermittently.

When the keep-warm process ends due to turning on the cancel switch, occurrence of an error, etc., the keep-warm process subroutine returns. In addition, during the heat keeping process, in the case of cooking rice porridge, the keep warm lamp is lit blinking, and in the case of regular rice cooking, the keep warm lamp is lit continuously.
The status of the rice being kept warm is distinguished and displayed.

This will be explained with reference to FIG. In this warming process,
First, in step 501, a process counter is set to (18) to indicate that the process is being kept warm. Next, in step 502, data during heat retention is set.

Next, the unit lock motor is turned off.

Next, in step 504, the exhaust motor is turned on and the exhaust fan unit is driven to start exhausting the water vapor generated from the automatic rice cooker 7.

Next, in step 505, it is determined whether the rice cooking menu is porridge cooking. If the rice is cooked in porridge,
The process advances to step 517 and the heat retention lamp is blinked. Then, in the fifth step 518, it is determined whether the cancellation switch is turned on. If the cancel switch is not turned on, keeping warm will continue, so proceed to step 521.
In step 521, it is determined whether or not there is a rice cooker initial, and in the next step 522, it is determined whether or not there is a rice cooker. If it is determined in step 521 that it is the rice cooker initial, or if the existence of the rice cooker cannot be confirmed in step 522,
In order to end the process during keeping warm, the process advances to step 515.

In these determination steps, if the rice cooker is not the rice cooker initial and there is a rice cooker, it is OK to continue keeping warm, so proceed to step 523, perform fan intermittent drive processing, and proceed to the next step 524. In step 518, a power outage confirmation process is performed and the process returns to step 518. Then, the process from step 518 is repeated to continue the process during heat retention in this case.

If it is determined in step 518 that the cancel switch is on, the process proceeds to step 519 to cancel the warming process and cancel the warming process, and then in step 520, the buzzer notification 1 The process then proceeds to step 515. Then, in step 515, the heat retention lamp is turned off, and in step 516, the contents of the process counter are set to (OO), and the process returns to the main routine.

On the other hand, if it is determined in step 505 that the rice is not cooked with porridge, then in step 506 it is determined whether or not the automatic rice cooker 7 is set to keep warm. If it is determined that the rice cooker is not warm, an error (E12) is displayed in step 525, and then the heat retention lamp is turned on in step 507. In this case, since the rice is kept warm normally, the heat retention lamp is lit continuously.

Then, in the next step 508, it is determined whether the cancellation switch is turned on. If the cancel switch is not on, the process will continue keeping warm, so the process first proceeds to step 511, in which it is determined whether or not there is a rice cooker initial, and in the next step 512, it is determined whether or not there is a rice cooker. judge.

If it is determined in step 511 that it is a rice cooker initial,
If the presence of the rice cooker cannot be confirmed in step 512, the process proceeds to step 515 to end the warming process.

In addition, -69- of step 511 and step 512
In the 7° determination step, if there is a rice cooker instead of the rice cooker initial, it is possible to continue keeping warm, so the process advances to step 513, where intermittent fan drive processing is performed. Next, a power outage confirmation process is performed in step 514, and the process returns to step 508. And step 508
Repeat the process from 1 to 3 to continue the process during heat retention in this case. If it is determined in step 508 that the cancel switch is turned on, the process proceeds to step 509 to cancel the warming process and cancel the warming process for the automatic rice cooker, and then in the next step 510 a buzzer is issued. 1 is performed, and the process proceeds to step 515. and,
In step 515, the heat retention lamp is turned off, and in step 51
Step 6 sets the contents of the process counter to (00) and returns to the main routine.

FIG. 11 is a flowchart showing the processing flow of intermittent fan drive performed in the subroutine of the warming process.

The intermittent fan drive process is a control routine for drive control of the exhaust fan unit. In the process here, in step 601, the step (18
), and determines whether 10 minutes have passed since entering
If it is not after 0 minutes, return immediately. If 10 minutes have passed since entering step (18), the process proceeds to step 602 and the exhaust fan is opened for 1 hour.
It is driven in an intermittent driving pattern of 0 seconds on and 1 minute off.

In this way, the intermittent drive of the exhaust fan during the warming process is started after a predetermined period of time after entering the control of the warming process, and the intermittent drive of the exhaust fan is The drive period during which the exhaust fan is driven is shorter than the rest period during which the exhaust fan is not driven.

Therefore, in such processing during heat retention, the exhaust fan is operated intermittently to reduce drive noise.
Furthermore, the exhaust noise is reduced by operating the exhaust fan at a lower exhaust capacity.

As mentioned above, the fully automatic rice cooking device here includes a rice storage and measuring unit with a built-in rice storage and measuring device inside the box body, a rice washing unit with a built-in rice washing device, and an automatic rice cooker. A main body control circuit is provided, which is a control device for controlling the devices of each unit. Main body of the control device A measuring process in which the control device takes out rice to be cooked from the rice storage and weighs it, a rice washing process in which the weighed rice is washed, and a rice preparation process in which the washed rice is set in an automatic rice cooker and the amount of water is adjusted. , the rice cooking process in which the automatic rice cooker is given a rice cooking start instruction and the rice cooking operation is monitored, and the warming process in which the automatic rice cooker monitors the heat retention state after rice cooking are controlled in sequence, and all the rice cooking processes are controlled in sequence. It is a fully automatic rice cooking device that performs such controls. When controlling all rice cooking processes, this main body control circuit checks each drive unit, communicates control data with the automatic rice cooker, and detects the status of the automatic rice cooker. At the same time, sequence control is performed for all rice cooking processes. The communication path for data communication in this case is
An optical transmitter/receiver provided on the side of the fully automatic rice cooker main body and an advance transmitter/receiver provided on the side of the automatic rice cooker are installed in positions close to each other and facing each other to form an optical signal communication path.

FIG. 12 is a sectional view of a main part explaining an optical signal communication path for control data communication between the fully automatic rice cooking device main body and the automatic rice cooker.

Referring to FIG. 12, an automatic rice cooker-side optical transmitter/receiver 49 is provided on the back side of the base of the automatic rice cooker 7, and on the side of the fully automatic rice cooker main body, a trolley 47a on which a slide rail is placed is provided with a An optical transmitter/receiver 48 on the main body side of the fully automatic rice cooker is provided inside a case '48a that projects into the space on the back side of the base of the automatic rice cooker 7.

When the automatic rice cooker 7 is set at a predetermined position in the rice cooking unit, the optical transmitter/receiver 48 on the side of the fully automatic rice cooker main body
and the automatic rice cooker side optical transmitter/receiver 49 face each other in close proximity to form an optical signal communication path 68 between the fully automatic rice cooker main body and the automatic rice cooker 7. The optical signal communication path 68 serves as a communication path for communicating control data. The optical signal communication path 68 has a short distance, and the space on the back φ side of the automatic rice cooker 7 is in a state where external light does not enter from the surroundings, so it has high noise resistance and the optical signal Since we communicate with
The dielectric noise and radio wave noise from the high-voltage circuit that controls the energization of the rice-cooking heater are also sufficiently strong.

The present invention has been specifically explained above based on examples, but
It goes without saying that the present invention is not limited to the embodiments described above, and can be modified in various ways without departing from the spirit thereof.

〔Effect of the invention〕

As explained above, according to the fully automatic rice cooking device of the present invention, the rice storage, rice polishing machine, II amounting device, rice washing device, and all the rice cooking devices in the rice cooker are installed in the box main body. Apparatus elements are provided, and a control device sequentially controls each rice cooking apparatus element to control the entire process of rice cooking control. Here, in order to control the rice milling process from brown rice, a rice milling process control function is provided as an option where the rice milling unit can be built into the main body or removed. In contrast to a rice polishing machine that is removably installed in the main body, the control device does not control the rice polishing process when it detects that the rice polishing machine has been removed.

This allows the rice to be polished from brown rice if desired.

It is possible to control all of the rice cooking control processes, including measuring, washing rice, adjusting the amount of water, and cooking rice, so that the rice can be deliciously cooked. In particular, since a rice polishing machine is added as an option, rice cooking cannot be performed while controlling the rice polishing process, so rice can be cooked without degrading the flavor of the rice.
