Next, an embodiment of the present invention shown in the drawings will be described.
As shown in FIG. 1, the rice cooker 1 of this invention arrange | positions the inner pot 4 in the inside of the rice cooker main body 3 opened and closed by the cover body 2 so that extraction is possible. Moreover, the rice cooker 1 is provided with rice cooking switch SW1, cancellation switch SW2, lid body temperature sensor S1, and inner pot temperature sensor S2 which are input elements. Furthermore, the rice cooker 1 includes a lid heater 6, which is an output element, a bottom heater 8, a display device 10 including an LCD display device, and a notification device 12 including a buzzer.

  The control device 14 composed of a microcomputer housed in the rice cooker body 3 includes a central processing unit (CPU) 15 which is a control means, a ROM 16 and a RAM 17 which are storage means, a first timer 19A which is a time measuring means, and a first timer. 2 timer 19B is provided. The ROM 16 stores a control program having a general-purpose mode control unit and an individual data unit. According to the control program, the CPU 15 cooperates with the first and second timers 19A and 19B, and receives input signals from the rice cooking switch SW1, the cancel switch SW2, the lid temperature sensor S1, and the inner pot temperature sensor S2. The lid heater 6, the bottom heater 8, the display device 10, and the notification device 12 are controlled.

  Next, a control program having the general-purpose mode control unit and the individual data unit will be described.

  First, the general-purpose mode control unit executes the mode control shown in the flowcharts of FIGS. 2 to 7, and the cooking flow is different because the cooker being controlled is different, or the same model cooker. It can be shared even when different cooking flows are executed. The definitions of parameters used in the flowcharts of FIGS. 2 to 7 are as follows.

OT: Number of output elements I: Number of input elements (including timer)
TM: Number of timers M: Number of modes

ot: Output element number (0 to OTn)
i: Input element number (0 to In)
tm: Timer number (0 to TMn)
m: Mode number

OTn: Maximum value of output element number ot (OTn = OT-1)
In: Maximum value of input element number i (In = I-1)
TMn: Maximum value of timer number tm (TMn = TM-1)
Mn: Maximum value of mode number m (Mn = M−1)

I _D [i]: Input from the input element of the input element number i D _OT [m] [ot]: Output to the output element corresponding to the output element number ot in the mode number m D _I [m] [i]: Mode transition condition D _J [m] [i] for the input element corresponding to input element number i in mode number m: Mode transition condition DI [m] [i] is satisfied and transition mode determination condition DH [m] [i ] No transition destination mode number _DH [m] [i]: Transition mode determination condition _DHJ1 [m] [i]: Transition destination when transition mode determination condition DH [m] [i] is satisfied mode number _{D HJ2 [m] [i]} : transition mode determination condition DH [m] [i] is the destination mode number D _R [m] in the case of not satisfied [tm]: corresponding to the timer ID tm in the mode number m Reset data indicating whether the timer has been reset (0: not reset, 1: reset)

  In this general-purpose mode control unit, first, in step S1 of FIG. 2, the number of output elements OT, the number of input elements I, the number of timers TM and the number of modes M are specified, the maximum value OTn of the output element number ot, the input element number i The maximum value In, the maximum value Mn of the mode number m, and the maximum value TMn of the timer number tm are calculated. The initial values of the output element number ot, the input element number i, and the mode number m are 0.

  As shown in step S1, the general-purpose mode control unit can specify the number of output elements OT and the number of input elements I. Therefore, the number of input elements such as heaters and the number of input elements such as sensors are different between models. Can be shared.

Next, mode output control is executed in step S2. In this mode output control, first, the output element number ot is set to 0 in step S2-1 in FIG. Next, in step S2-2, the output D _OT [m] [ot] is output to the corresponding output element, and in step S2-3, 1 is added to the output element number ot. Steps S2-2 and S2-3 are repeated until it is determined in step 2-4 that the output element number ot is greater than or equal to the maximum value OTn. If it is determined in step S2-4 that the output element number ot is greater than or equal to the maximum value OTn, the mode output control in that mode ends. In addition, the hardware control program for operating each output element in said step S2-2 differs for every output element.

Subsequent to the mode output control, the mode input control in step S3 of FIG. 2 is executed. In this mode input control, first, the input control number i is set to 0 in step S3-1 of FIG. Next, input I _D [i] is input from the corresponding input element in step S3-2, and 1 is added to the input element number i in step S3-3. Steps S3-2 and S3-3 are repeated until it is determined in step 3-4 that the input element number i is greater than or equal to the maximum value In. If it is determined in step S3-4 that the input element number i is greater than or equal to the maximum value In, the mode input control in that mode ends. Note that the hardware control program for operating individual input elements in step S3-2 is different for each input element.

  Following the mode input control, whether or not the mode transition condition is satisfied is determined in step S4 of FIG. If the mode transition condition is satisfied in step S4, the mode transition of step S5 is executed. If not, step S2 and step S3 are repeated.

In this mode transition condition establishment judgment control, first, the input element number i is set to 0 in step S4-1 in FIG. Next, in step S4-2, it is determined whether or not the mode transition condition D _I [m] [i] exists. If the mode transition condition D _I [m] [i] exists in step S4-2, the process proceeds to step S4-3. If it is determined in step S4-3 that the mode transition condition DI [m] [i] is satisfied, the process proceeds to step S5 in FIG. 2 in step S4-4, and the determination of the mode transition condition in that mode is completed. .

On the other hand, if the mode transition condition in step S4-2 D _I [m] mode transition condition when [i] is not present and the step S4-3 D _I [m] where [i] is not satisfied, step S4 At -5, 1 is added to the input element number i. If the input element number i is not greater than or equal to the maximum value In in step S4-6, the process returns to step S4-2. If the input element number i is greater than or equal to the maximum value In, the process returns to step S2 in FIG.

In the mode transition of step S5 of FIG. 1, first, it is determined whether or not the corresponding transition mode determination condition D _H [m] [i] exists in step S5-1 of FIG. _{If H} [m] [i] does not exist, the mode number m is set to the destination mode number D _J [m] [i] in step S5-2, and the mode transition ends.

On the other hand, if the corresponding transition mode determination condition D _H [m] [i] exists in step S5-1, is the transition mode determination condition D _H [m] [i] established in step S5-3? It is determined whether or not. If the transition mode determination condition D _H [m] [i] is satisfied in step S5-3, the mode number m is set to the transition destination mode number D _HJ1 [m] [i] in step _S5-4 , and the mode is set. The migration ends. On the other hand, if the transition mode determination condition D _H [m] [i] is not satisfied in step S5-3, the mode number m is set to the transition destination mode number D _HJ2 [m] [i] in step S5-5. The mode transition ends.

As described above, in the mode transition, it is not only determined whether the mode transition condition D _I [m] [i] is satisfied, but if there is a transition mode determination condition D _H [m] [i], the transition is performed based on the condition. Since the previous mode is determined, a more complicated cooking flow can be realized.

Following the mode transition, the timer operation in step S6 in FIG. 2 is executed. In this timer operation, first, the timer number tm is set to 0 in step S6-1 in FIG. Next, if the reset data D _R [m] [tm] is 1 in step S6-2, the corresponding timer is reset in step S6-3, and then the process proceeds to step S6-4. On the other hand, if the reset data D _R [m] [tm] is not 1 in step S6-2, the process proceeds to step S6-4 without resetting the timer. In step S6-4, 1 is added to the timer number tm. Next, if the timer number tm is greater than or equal to the maximum value TMn in step S6-5, the timer operation ends. On the other hand, if the timer number tm is not greater than or equal to the maximum value TMn in step S6-5, the process returns to step S6-2.

  The individual data part of the control program is a data group consisting of mode output control, mode transition condition, transition mode discrimination condition, transition destination mode and reset data in each mode of the general purpose mode control part, and is used in the general purpose mode control part. It consists of data such as specific numerical values of each parameter. The general-purpose mode control unit can be shared even when the cooking flow is different due to a difference in model or the like, whereas the individual data unit is composed of data unique to the individual cooking flow. The individual data part of the rice cooker 1 shown in FIG. 1 is as shown in Tables 1 and 2.

  In the rice cooker 1 of FIG. 1, the output element number OT is 4, the input element number I is 6, the timer number TM is 2, and the mode number M is 20. The output element number ot has a maximum value OTn of 3, 0 corresponds to the lid heater 6, 1 corresponds to the bottom heater 8, 2 corresponds to the display device 10, and 3 corresponds to the notification device 12. The input element number i has a maximum value In of 5; 0 is a rice cooking switch SW1, 1 is a cancel switch SW2, 2 is a lid temperature sensor S1, 3 is an inner pot temperature sensor S2, 4 is a first timer 19A, 5 corresponds to the second timer 19B. Further, the timer number tm has a maximum value TMn of 1, 0 corresponds to the first timer 19A, and 1 corresponds to the second timer 19B. Furthermore, the maximum value Mn of the mode number m is 19.

  Next, the cooking flow realized by the CPU 15 executing the control program comprising the general-purpose mode control unit shown in the flowcharts of FIGS. 2 to 7 and the individual data units of Tables 1 and 2 will be described in detail. To do.

First, in the mode number 0, the lid heater 6, the bottom heater 8, and the notification device 12 are all off and nothing is displayed on the display device 10. When the user turns on the rice cooking switch SW1, the mode transition condition D _I [0] [0] is established, and after the first and second timers 19A and 19B are reset, the transition mode number D _J [0] [0] Shift to mode number 1 corresponding to. In any of the following mode numbers 1 to 19, when it is detected that the second switch 19B is on, the mode number 0 is shifted to.

  Mode numbers 1 to 4 are preheating steps, and the bottom heater 8 is operated so that the temperature detected by the inner pot temperature sensor S2 is 45 ° C. for about 10 minutes.

Of these modes, mode number 1 will be described. The lid heater 6 is in an off state, the bottom heater 8 is in an on state, the notification device 12 is in an off state, and “preheating” is displayed on the display device 10. When the detected temperature of the inner pan temperature sensor S2 exceeds 45 ° C., the mode transition condition D _I [1] [3] is established, and after the first and second timers 19A and 19B are reset, the transition mode number D _J [1] Moves to mode number 3 corresponding to [3]. When the time counted by the first timer 19A reaches 10 seconds, the mode transition condition D _I [1] [4] is satisfied, and after the first and second timers 19A and 19B are reset, the transition destination Transition is made to mode number 2 corresponding to mode number D _J [1] [4].

When the time counted by the second timer 19B reaches 600 seconds in the mode number 3 or mode number 4 included in the preheating process, the mode transition conditions D _I [3] [5], D _I [4] [5] are changed. After it is established and the first timer 19A is reset, the mode shifts to the mode number 5 corresponding to the transfer destination mode number D _J [3] [5], D _J [4] [5]. This mode number 5 is a middle paddy process, the lid heater 6 is in the off state, the bottom heater 8 is in the on state, the notification device 12 is in the off state, and “displaying rice” is displayed on the display device 10. When the temperature detected by the inner pan temperature sensor S2 exceeds 55 ° C., the mode transition condition D _I [5] [3] is established, and after the first and second timers 19A and 19B are reset, the transition mode number D _J [5] The mode number 6 corresponding to [3] is entered.

Mode number 6 is a capacity determination step, in which the capacity in the inner pot 4 is determined based on the detected temperature of the inner pot temperature sensor S2 120 seconds after the detected temperature of the inner pot temperature sensor S2 exceeds 55 ° C.
Specifically, in mode number 6, the lid heater 6 is in the off state, the bottom heater 8 is in the on state, the notification device 12 is in the off state, and “displaying rice” is displayed on the display device 10. When the time measured by the first timer 19A reaches 120 seconds, the mode transition condition D _I [6] [4] is satisfied. In this case, there is a transition mode determination condition D _H [6] [4] indicating whether or not the detected temperature of the inner pan temperature sensor S2 exceeds 70 ° C. When the transition mode determination condition D _H [6] [4] is satisfied, it is determined that the capacity in the inner pot 4 is small and corresponds to the transition destination mode number D _HJ1 [6] [4]. If it is not established, it is determined that the capacity of the inner pot 4 is large, and the mode number 10 corresponding to the destination mode number D _HJ2 [6] [4] is transferred.

  Mode numbers 7 to 12 are rice cooking steps after the middle paddy process. Mode numbers 7 to 9 correspond to the case where the contents of the inner pot 4 are small, and mode numbers 10 to 12 are the contents of the inner pot 4. It corresponds to the case where there are a lot of things.

  In the mode numbers 7 to 9 corresponding to the small amount, first, the bottom heater 8 is maintained in the ON state until the detected temperature of the lid temperature sensor S1 exceeds 85 ° C. in the mode number 7, and then the inner pot temperature sensor S2 Until the detected temperature exceeds 115 ° C., the state in which the bottom heater 8 is turned on for 8 seconds by the mode number 8 and the state in which the bottom heater 8 is turned off for 7 seconds by the mode number 9 are repeated. On the other hand, in the mode number 10 to the mode number 12 corresponding to the large amount, first, the bottom heater 8 is maintained in the ON state until the detected temperature of the lid temperature sensor S1 exceeds 90 ° C. in the mode number 10, and then the inner heater 8 is turned on. Until the temperature detected by the pan temperature sensor S2 exceeds 120 ° C., the state in which the bottom heater 8 is turned on for 12 seconds by the mode number 11 and the state in which the bottom heater 8 is turned off for 4 seconds by the mode number 12 are repeated.

When the detected temperature of the inner pan temperature sensor S2 exceeds 115 ° C or 120 ° C in mode numbers 8, 9, 11, and 12, the mode transition conditions D _I [8] [3], D _I [9] [3], D _I [11] [3], D _I [12] [3] are established, and the destination mode numbers D _J [8] [3], D _J [9] [3], D _J [11] [3] , D _J [12] [3], the mode number 13 is entered.

  Mode numbers 13 and 14 are unevenness steps, and the bottom heater 8 is maintained in an off state, while the lid heater 6 is repeatedly turned on and off, and the temperature detected by the lid temperature sensor S1 is 119 ° C. to 120 ° C. for 720 seconds. Heating is performed so that the temperature is maintained in the range of ° C. When 720 seconds have elapsed from the start of mode numbers 13 and 14, the mode number 15 is entered.

  The mode number 15 is a rice cooking end notification, and the notification device 12 is operated to notify the user that rice cooking has ended. In mode number 15, the lid heater 6 and the bottom heater 8 are in an off state, and the display device 10 displays “cooking rice”. After the mode number 15 continues for 5 seconds, the mode number 16 is entered.

  Mode numbers 16 and 17 are heat retention steps after the completion of rice cooking. The lid heater 6 and the bottom heater 8 are repeatedly turned on and off, and the temperature detected by the inner pan temperature sensor S2 is maintained in the range of 69 ° C to 70 ° C. Heat as follows. The heat retention process by the mode numbers 16 and 17 continues until the cancel switch SW2 is turned on.

  When the time counted by the second timer 19B reaches 1200 seconds in the mode number 7 to 12 which is the rice cooking process after the middle pappa process, it is determined that an abnormality has occurred, and the mode number 18 is entered.

  In mode number 18, the lid heater 6 and the bottom heater 8 are turned off, and the heating of the inner pot 4 is stopped. In addition, “abnormal” is displayed on the display device 10 and the notification device 12 is activated to notify the user of the occurrence of the abnormality. When 5 seconds have elapsed from the start of the mode number 18, the process proceeds to the mode number 19, and the lid heater 6 and the bottom heater 8 are held in the OFF state unless the cancel switch SW2 is turned on.

  As described above, the cooking flow of the rice cooker 1 is realized by the control program including the general-purpose mode control unit and the individual data unit. Therefore, when a malfunction occurs in the cooking flow or when the cooking flow needs to be changed. The control program can be corrected and changed only by correcting and changing only the individual data.

  In the rice cooker 1, both the general-purpose mode control unit and the individual data unit are stored in the ROM 16. However, the input / output element number designation part (step S <b> 1 in FIG. 2) of the individual data unit and the general-purpose mode control unit is stored in the RAM 17. It is good also as rewritable by memorizing. In this case, the control program can be easily changed during product development.

  As described above, the general-purpose mode control unit of the control program shown in FIGS. 2 to 7 is not limited to the rice cooker 1 but can be used for different types of cookers. Therefore, when developing a control program for a new model, it is only necessary to newly create an individual data section, and the development period can be shortened.

  For example, the general-purpose mode control unit includes a heater, a motor for driving a stirring blade, a display device, and a notification device as output elements, an operation switch, a stop switch, and a temperature sensor as input elements, and one The present invention can be used for a control program for executing a cooking flow of an automatic bread maker having a timer.
