  In FIG. 2, first, in the standby state, the presence / absence of input from the second input means 4 is checked at step 31. If there is no input, the presence / absence of input from the first input means 3 is checked at step 32. If there is no input from the first input means 3 again, the process returns to step 31 to continue the standby process. When the user operates the first input means 3 in step 32, the process proceeds to step 33, in which the control means 6 drives the heating means 2 according to the heating program corresponding to the amount of rice cooked to heat the pan 1 and the cooked rice is heated. Done. Subsequently, the routine proceeds to step 34 where it is checked whether or not there is an input from the third input means 5. If there is this input, the process returns to step 31 to enter a standby state. If this input is not present, it is checked in step 35 whether cooking rice has been completed. If the rice cooking has not been completed, the process returns to step 33 to continue the rice cooking operation. If the end of rice cooking is detected in step 35, the process proceeds to step 36, the heat retention elapsed time is initialized, the process proceeds to step 37, the heat retention automatic end flag is reset, and the heat retention state is entered.

  Moreover, also when the input from the 2nd input means 4 is received at step 31, it enters into a heat retention state. In this case, the process proceeds from step 31 to step 45, where it is determined whether the heat retention time has passed the first predetermined time of 96 hours, and if it has not elapsed, the process proceeds to step 38. Then, in step 46, the time keeping time of the first clock means 7 is set to 24 hours by the thermometer or the time setting means 9. Thereby, it is possible to automatically end the heat retaining operation in 72 hours which is the second predetermined time.

  In the next step 38, the control means 6 drives the heating means 2 according to the program for the heat insulation operation, and the pot 1 is heated to keep the heat.

  In FIG. 4, first, in the standby state, the presence or absence of input from the second input means 4 is checked in step 51, and if there is no input, the presence or absence of input from the first input means 3 is checked in step 52. If there is no input from the first input means 3 again, the process returns to step 51 to continue the standby process. When the user operates the first input means 3 in step 52, the process proceeds to step 53. In step 53, the control means 6 drives the heating means 2 according to the heating program corresponding to the amount of rice cooked to heat the pot 1 and the cooked rice is heated. Done. Subsequently, the routine proceeds to step 54 where it is checked whether or not there is an input from the third input means 5. If there is this input, the process returns to step 51 to enter a standby state. If this input is not present, it is checked in step 55 whether rice cooking has been completed. If the rice cooking has not been completed, the process returns to step 53 to continue the rice cooking operation.

  If the end of rice cooking is detected in step 55, the process proceeds to step 56, the heat retention elapsed time is initialized, and the process proceeds to step 57 to enter the heat retention state. Further, when the input from the second input means 4 is accepted in step 51, the process proceeds to step 57 and enters the heat insulation state. In step 57, the control means 6 drives the heating means 2 according to the heat retention operation program to heat the pot 1 and keep the heat. In subsequent step 58, the lid opening / closing detection means 12 determines whether or not the lid is open. If the lid is open, the process proceeds to step 59, and if the lid is closed, the process proceeds to step 61. In step 61, the lid opening time counted by the second clock means 13 is initialized, and then the routine proceeds to step 62.

  In step 59, the time for which the lid is open is counted. At the next step 60, it is determined whether the lid opening time counted by the second heat insulation automatic end means 14 has passed the third predetermined time of 5 minutes, and if it has elapsed, the process proceeds to step 51 and the heat insulation is terminated. . If not, the process proceeds to step 62. In step 62, the presence / absence of input from the third input means 5 is checked. If there is this input, the process returns to step 51 to enter a standby state. If there is no such input, the process returns to step 57 to continue the heat retaining operation.

  In FIG. 6, first, in the standby state, the presence or absence of an input from the second input means 4 is checked in step 71, and if there is no input, the presence or absence of an input from the first input means 3 is checked in step 72. If there is no input from the first input means 3 again, the process returns to step 71 to continue the standby process. When the user operates the first input means 3 in step 72, the process proceeds to step 73. In step 73, the control means 6 drives the heating means 2 according to the heating program corresponding to the amount of rice cooked to heat the pan 1 and the cooked rice is heated. Done. Subsequently, the routine proceeds to step 74, where the presence / absence of input from the third input means 5 is checked. If there is this input, the process returns to step 71 to enter a standby state. If this input is not present, it is checked in step 75 whether rice cooking has been completed.

  If the cooking has not been completed, the process returns to step 73 to continue the cooking operation. If the end of cooking is detected in step 75, the lid open flag is reset in step 76, and then the process proceeds to step 77 to enter the heat retaining state. Further, when the input from the second input means 4 is accepted in step 71, the process proceeds to step 77 and enters the heat insulation state. In step 77, the control means 6 drives the heating means 2 according to the heat retention operation program to heat the pot 1 and keep the heat. In subsequent step 78, the lid opening / closing detection means 12 determines whether the lid has been opened or closed. If the lid is opened / closed, the process proceeds to step 79. If the lid is not opened / closed, the process proceeds to step 81.

  In step 79, the time measured by the third clock means 15 is initialized, and after that, the lid opening / closing flag is set in step 80, and then the routine proceeds to step 81. If the lid opening / closing flag is not set in step 81, the process proceeds to step 84. If the lid opening / closing flag is set, the process proceeds to step 82. In step 82, the third clock means 15 measures the elapsed time since the lid was opened and closed. Thereafter, the process proceeds to step 83.

  In step 83, it is determined by the third heat insulation automatic ending means 16 whether a fourth predetermined time of 72 hours has elapsed. If the elapsed time is 72 hours or more, the process proceeds to step 71 and returns to the standby state. If the elapsed time is less than 72 hours, the process proceeds to step 84. In step 84, the presence or absence of input from the third input means 5 is checked. If there is this input, the process returns to step 71 to enter a standby state. If there is no such input, the process returns to step 77 to continue the heat retaining operation. In the present embodiment, the fourth predetermined time for automatically terminating the heat retaining operation is 72 hours, but it may not be 72 hours in particular.

Reference numeral 10 denotes display means such as an LCD, 17 denotes notification means such as a buzzer, and 18 denotes second control means for driving the display means 10 and the notification means 17.

  In FIG. 8, first, in the standby state, the presence / absence of input from the second input means 4 is checked in step 91. If there is no input, the presence / absence of input from the first input means 3 is checked in step 92. If there is no input from the first input means 3 again, the process returns to step 91 to continue the standby process. If a user operates the 1st input means 3 by step 92, it will progress to step 93, and the control means 6 will drive the heating means 2 with the heating program according to the amount of rice cooking in step 93, the pot 1 will be heated, and heating rice cooking will be carried out. Done. Subsequently, the routine proceeds to step 94 where it is checked whether or not there is an input from the third input means 5. If there is this input, the process returns to step 91 to enter a standby state. If this input is not present, it is checked in step 95 whether cooking has been completed. If the rice cooking has not been completed, the process returns to step 93 to continue the rice cooking operation.

  If the end of rice cooking is detected in step 95, the process proceeds to step 96 to initialize the heat insulation elapsed time, and then proceeds to step 97 to enter the heat insulation state. Also, when the input from the second input means 4 is accepted in step 91, the process proceeds to step 97 and enters the heat insulation state. In this case, the process proceeds from step 91 to step 103, where the heat insulation time has passed 96 hours or more. Judgment is made. If 96 hours or more have not passed, the process proceeds to step 97, but if it has elapsed, in step 104, the time measured by the first clock means 7 is set to 24 hours. Thereby, it is possible to automatically end the heat retaining operation in 72 hours which is the second predetermined time. In the next step 97, the control means 6 drives the heating means 2 according to the heat retention operation program to heat the pot 1 and keep the heat.

  Next, at step 98, the elapsed warming time is measured, and at the next step 99, the first warming automatic end means 8 determines whether the warming elapsed time has passed the first predetermined time of 96 hours. If the heat retention elapsed time is 96 hours or more, the process proceeds to step 101, and if not, the process proceeds to step 100. In step 101, “U13” is displayed on the display means 10 by the second control means 18. Thereafter, the process proceeds to step 102 where the presence / absence of input from the third input means 5 is checked. If this input is present, the process returns to step 91 to enter the standby state. If there is no input, the process returns to step 101. In step 100, the presence / absence of input from the third input means 5 is checked. If there is this input, the process returns to step 91 to enter a standby state. If there is no such input, the process returns to step 97 to continue the heat retaining operation.

  In this embodiment, “U13” is displayed on the display means 10 in step 101. However, the display may not be “U13” but may be a display by LED. In step 101, the display unit 10 alone indicates that the heat retention elapsed time exceeds a predetermined time. However, the display unit 10 displays and the notification unit not only by the display unit 10 but also by the notification unit 17 alone. 17 may be used.

If there is no input, the presence / absence of input from the first input means 3 is checked in step 112. If there is no input from the first input means 3 again, the process returns to step 111 to continue the standby process. If a user operates the 1st input means 3 by step 112, it will progress to step 113, and the control means 6 will drive the heating means 2 with the heating program according to the amount of rice cooking in step 113, the pot 1 will be heated, and heating rice cooking will be carried out. Done. Subsequently, the routine proceeds to step 114 where it is checked whether or not there is an input from the third input means 5. If there is this input, the process returns to step 111 to enter a standby state. If this input is not present, it is checked in step 115 whether cooking has been completed.

  If the rice cooking has not been completed, the process returns to step 113 to continue the rice cooking operation. If the end of rice cooking is detected in step 115, the process proceeds to step 116, the heat insulation elapsed time is initialized, and the process proceeds to step 117 to enter the heat insulation state. Also, when the input from the second input means 4 is accepted in step 111, the process proceeds to step 117 and enters the heat insulation state. In this case, the process proceeds from step 111 to step 122, where the heat insulation time is the first predetermined value. It is determined whether or not 96 hours, i.e., has elapsed, and if the heat retention time has not exceeded 96 hours, the process proceeds to step 117, but if it has elapsed, the time measured by the first clock means 7 is determined in step 123. Is set to 24 hours. Thereby, it is possible to automatically end the heat retaining operation in 72 hours which is the second predetermined time. In the next step 117, the control means 6 drives the heating means 2 according to a program for keeping warm, and the pot 1 is heated to keep warm. Next, in step 118, the warming elapsed time is measured, and in the next step 119, it is determined by the first warming automatic end means 8 whether the warming elapsed time is 96 hours which is the first predetermined time. If the heat retention elapsed time is 96 hours or more, the process proceeds to step 121, and if not, the process proceeds to step 120. In step 121, the third control means 19 drives the notification means 17 to notify that the heat retention is automatically ended.

  Thereafter, the process proceeds to step 111 and returns to the standby state. In step 120, the presence / absence of input from the third input means 5 is checked. If there is this input, the process returns to step 111 to enter a standby state. If there is no such input, the process returns to step 117 and the heat retaining operation is continued. In this embodiment, only the notifying unit 17 notifies that the heat insulation is automatically terminated in step 121. However, the display unit 10 may not be the only notifying unit 17 but the display unit 10 may display and notify the display. Notification by means 17 may be used.

(Example 6)
Hereinafter, a sixth embodiment of the present invention will be described with reference to FIGS.

  In FIG. 11, the parts denoted by the same reference numerals as those in FIG. 15 are the same as the components described in the conventional example, and thus the details are omitted. Reference numeral 10 denotes display means such as an LCD, 17 denotes notification means such as a buzzer, and 20 denotes fourth control means for driving the display means 10 and the notification means 17.

  In FIG. 12, first, in the standby state, the presence / absence of input from the second input means 4 is checked in step 131. If there is no input, the presence / absence of input from the first input means 3 is checked in step 132. If there is no input from the first input means 3 again, the process returns to step 131 to continue the standby process. When the user operates the first input means 3 in step 132, the process proceeds to step 133. In step 133, the control means 6 drives the heating means 2 according to the heating program corresponding to the amount of cooked rice to heat the pan 1 and the cooked rice is heated. Done. Subsequently, the routine proceeds to step 134 where it is checked whether or not there is an input from the third input means 5. If there is this input, the process returns to step 131 to enter a standby state. If this input is not present, it is checked in step 135 whether cooking rice has been completed.

  If the rice cooking has not been completed, the process returns to step 133 to continue the rice cooking operation. If the end of cooking is detected in step 135, the process proceeds to step 136, the heat retention elapsed time is initialized, and the process proceeds to step 137 to enter the heat retention state. Also, when the input from the second input means 4 is accepted in step 131, the process proceeds to step 137 and enters the heat insulation state. In this case, the process proceeds from step 131 to step 143, where the heat insulation time is the first predetermined value. It is determined whether 96 hours or more, which is the time for the above, has passed. If the heat retention time has not passed for 96 hours, the process proceeds to step 137. If it has elapsed, the time of the first clock means 7 is counted in step 144. Set the time to 24 hours. Thereby, it is possible to automatically end the heat retaining operation in 72 hours which is the second predetermined time. In the next step 137, the control means 6 drives the heating means 2 according to a program for keeping warm, and the pot 1 is heated to keep warm.

  Next, in step 138, the elapsed warming time is measured, and in the next step 139, it is determined whether the warmed elapsed time is 72 hours, which is a predetermined time. In other words, it is determined whether it is 24 hours before the automatic warming stop which is the fifth predetermined time. If the heat retention elapsed time is 72 hours, the process proceeds to step 140 and the fourth control means 20 drives the notification means 17 to notify that the heat retention has been performed for a long time. If the heat retention elapsed time is less than 72 hours, the process proceeds to step 141. In step 141, it is determined by the first heat retention automatic end means 8 whether the heat retention elapsed time is 96 hours, which is the first predetermined time. If the heat retention elapsed time is 96 hours or more, the process proceeds to step 131 and returns to the standby state. If the heat retention elapsed time is less than 96 hours, the process proceeds to step 142. In step 142, the presence / absence of input from the third input means 5 is checked. If there is this input, the process returns to step 131 to enter a standby state. If there is no such input, the process returns to step 137 to continue the heat retaining operation.

  In the present embodiment, the fifth predetermined time is 24 hours. However, the fifth predetermined time is not particularly limited to 24 hours, and may be not only 24 hours but also a plurality of times. Further, in step 140, only the notification means 17 notifies that the temperature is kept for a long time. However, not only the notification means 17 but also the display by the display means 10 and the notification means 17 may be displayed only by the display means 10. Information may be provided.

If there is no input, the presence / absence of input from the first input means 3 is checked in step 152. If there is no input from the first input means 3 again, the process returns to step 151 to continue the standby process. If a user operates the 1st input means 3 by Step 152, it will progress to Step 153, and in Step 153, control means 6 will drive heating means 2 with a heating program according to the amount of rice cooking, and pan 1 will be heated and heating rice cooking will be carried out. Done.

  Subsequently, the routine proceeds to step 154, where the presence / absence of input from the third input means 5 is checked. If there is this input, the process returns to step 151 to enter a standby state. If this input is not present, it is checked in step 155 whether cooking has been completed. If the rice cooking has not been completed, the process returns to step 153 to continue the rice cooking operation. If the end of rice cooking is detected in step 155, the process proceeds to step 156 to initialize the heat insulation elapsed time, and the process proceeds to step 157 to enter the heat insulation state. Also, when the input from the second input means 4 is accepted in step 151, the process proceeds to step 157 and enters the heat insulation state. In this case, the process proceeds from step 131 to step 143, where the heat insulation time is the first predetermined value. It is determined whether 96 hours or more, which is the time of the time, has passed. If the heat retention time has not passed 96 hours, the process proceeds to step 157. If it has elapsed, the time of the first clock means 7 is counted in step 163. Set the time to 24 hours. Thereby, it is possible to automatically end the heat retaining operation in 72 hours which is the second predetermined time.

  In the next step 157, the control means 6 drives the heating means 2 according to a program for keeping warm, and the pot 1 is heated to keep warm. Next, in step 158, the warming elapsed time is measured, and in the next step 159, it is determined by the first warming automatic end means 8 whether the warming elapsed time has passed the first predetermined time of 96 hours. If the heat retention elapsed time is 96 hours or more, the process proceeds to step 160, and if the heat retention elapsed time is less than 96 hours, the process proceeds to step 161. In step 160, the fifth control means 21 displays "U14" on the display means 10. Thereafter, the process proceeds to step 161. In step 161, the presence or absence of input from the third input means 5 is checked. If there is this input, the process returns to step 151 to enter a standby state. If there is no such input, the process returns to step 157 to continue the heat retaining operation.

  In this embodiment, “U14” is displayed on the display means 10 in step 160. However, the display may not be “U14” in particular, and may be displayed by an LED. In step 160, the display means 10 alone indicates that the heat retention elapsed time exceeds a predetermined time. However, the display means 10 and the notification means are not limited to the display means 10 but also the notification means 17 alone. 17 may be used.

  As described above, the present invention can be applied not only to household use but also to uses such as commercial rice cookers.
