Furthermore, the display part 3 has the mode display part 25 which displays the cooking condition of rice, such as normal, hard, soft, cooking, rice cracker, Chinese rice cake.

  The segment display unit 21 displays the remaining cooking time by the cooker body 2 in segments. The segment display unit 21 displays a two-digit number in a segment, and has a portion indicating a 1's place and a portion indicating a 10's place. Moreover, the hour digit segment display part 22 is provided in the 10th place side of the segment display part 21, and displays the hour digit in a segment by a segment. The hour digit segment display unit 22 displays a two-digit number in a segment, and has a portion indicating a 1's place and a portion indicating a 10's place.

  Then, the control unit 30 displays the minute digits of the time on the segment display unit 21 and displays the time on the hour digit segment display unit 22 and the segment display unit 21. A colon display unit 26 for displaying a colon is provided between the hour digit segment display unit 22 and the segment display unit 21.

When the remaining cooking time is in minutes, the display of “time” is deleted and “completion after minutes” is displayed. On the other hand, when the remaining cooking time is in units of hours, the display of “minutes” is deleted and “completion after time” is displayed.

  FIG. 4 is a diagram showing a display example of the display unit 3 according to Embodiment 1 of the present invention. As shown in FIG. 4, for example, when the remaining cooking time is in units of minutes and is about 68 minutes, the control unit 30 displays “68” on the segment display unit 21. In addition, the control unit 30 displays “about” on the about display unit 23. Further, the control unit 30 causes the completion display unit 27 to display “completion in minutes”. In this way, the control unit 30 causes the display unit 3 to display “finished after about 68 minutes”.

  FIG. 5 is a diagram showing a display example of the display unit 3 according to Embodiment 1 of the present invention. As shown in FIG. 5, for example, when the remaining cooking time is a time unit and is about 2 hours, the control unit 30 causes the segment display unit 21 to display “2”. In addition, the control unit 30 displays “about” on the about display unit 23. Further, the control unit 30 causes the completion display unit 27 to display “completion after time”. In this way, the control unit 30 causes the display unit 3 to display “Finished after about 2 hours”.

  FIG. 6 is a block diagram of the control unit 30 according to Embodiment 1 of the present invention. As illustrated in FIG. 6, the control unit 30 includes a determination unit 32, a conversion unit 33, and a time display unit 34. Furthermore, the control unit 30 includes a calculation unit 31, for example.

  The calculating means 31 calculates the remaining cooking time by the cooker body 2 and calculates the remaining cooking time based on the detection result of the temperature detection unit 13, for example. In addition, the heating cooker 1 may be provided with the weight detection part (not shown) which detects weights, such as the amount of rice cooking. In this case, the calculation unit 31 calculates the remaining cooking time based on the detection result of the weight detection unit.

  The determination means 32 determines whether the cooking remaining time is 100 minutes or more.

  The conversion means 33 converts the remaining cooking time from minutes to hours when the determination means 32 determines that the remaining cooking time is 100 minutes or more. Specifically, the converting means 33 divides the value obtained by subtracting 1 from the remaining cooking time by 60, and further adds 1 to convert the remaining cooking time from minutes to hours. That is, the conversion means 33 converts the remaining cooking time from minutes to hours using the following formula (1).

  Cooking time remaining in units of time = (Remaining cooking time in minutes−1) / 60 + 1 (1)

  The time display means 34 displays the remaining cooking time converted into time units in the conversion means 33 on the segment display unit 21 with a maximum of two digits. Moreover, the time display means 34 makes the interval which the cooking remaining time displayed on the segment display part 21 reduces regardless of the amount of rice cooking after cooking by the cooking appliance main body 2 transfers to a steaming process. .

  The cooking remaining time is displayed according to 3 go cooking when it is a cooker of 5.5 go cooking. When the amount of rice is more than 3 go, the cooking time is longer than 3 go cooking, so the actual remaining cooking time is longer than the displayed remaining cooking time. When the amount of rice is less than 3 go, the cooking time is shorter than 3 go cooking, so the actual remaining cooking time is shorter than the displayed remaining cooking time.

  Here, when cooking shifts to the steaming process, the remaining cooking time is equal regardless of the amount of cooked rice. That is, when cooking moves to the steaming process, the actual remaining cooking time is determined. For this reason, in the steaming step, the interval at which the displayed cooking time decreases is changed, and the displayed remaining cooking time is set to zero at the time when the cooking is actually finished. After the cooking by the cooker body 2 shifts to the steaming process, the time display means 34 makes the interval at which the cooking remaining time displayed on the segment display unit 21 decreases regardless of the amount of cooked rice. Thereby, it is suppressed that the user feels uncomfortable due to the decrease in the displayed cooking remaining time being different from the actual time.

  Moreover, the time display means 34 erase | eliminates the display of the cooking remaining time displayed on the segment display part 21, after predetermined time passes since cooking of the cooking appliance main body 2 was started. Furthermore, the time display means 34 displays the remaining cooking time on the segment display unit 21 when the display operation unit 5 is operated. Furthermore, the time display means 34 displays the remaining cooking time on the segment display unit 21 when it is detected by the person detection unit 14 that a person has approached the cooker body 2.

  Here, the alerting | reporting part 12 alert | reports that it changed, when the cooking remaining time displayed on the segment display part 21 is changed from the time unit to the minute unit. When the remaining cooking time displayed on the segment display unit 21 is changed from the hour unit to the minute unit, the control unit 30 notifies the notification unit 12 of the change. When the alerting | reporting part 12 is a speaker, the alerting | reporting part 12 alert | reports by voice that the cooking remaining time was changed from the time unit to the minute unit. Accordingly, the user can recognize that the time unit has been changed to the minute unit.

  7 and 8 are diagrams illustrating an example of the notification unit 12 according to Embodiment 1 of the present invention. As shown in FIGS. 7 and 8, the notification unit 12 is not limited to the speaker, and may be realized by a display pattern by the segment display unit 21. The control unit 30 first erases the display of one segment in the segment display unit 21. Next, the control unit 30 displays the segment and erases the display of the segment adjacent to the segment. By repeating this, the segment display unit 21 rotates the portion where the segment display is erased.

  FIG. 9 is a flowchart showing the operation of the cooking device 1 according to Embodiment 1 of the present invention. Next, the operation of the heating cooker 1 according to the first embodiment will be described. As shown in FIG. 9, when the display on the display unit 3 starts, first, the remaining cooking time is calculated by the calculation means 31 (step ST1). Next, it is determined by the determination means 32 whether a cooking remaining time is 100 minutes or more (step ST2).

  When it is determined that the remaining cooking time is less than 100 minutes (No in step ST2), the time display means 34 displays the remaining cooking time in minutes on the segment display unit 21 with a maximum of two digits (step ST4). . Thereafter, the process proceeds to step ST5. On the other hand, when it is determined that the remaining cooking time is 100 minutes or more (Yes in step ST2), the conversion means 33 converts the remaining cooking time from minutes to hours. Specifically, it is converted using the above formula (1). And the cooking remaining time converted into the time unit is displayed on the segment display part 21 by the time display means 34 by a maximum of 2 digits (step ST3). Thereafter, the process proceeds to step ST5.

  In step ST5, the control unit 30 determines whether 1 minute has elapsed. If 1 minute has not elapsed (No in step ST5), the process returns to step ST2. On the other hand, when 1 minute has passed (Yes in step ST5), the cooking remaining time is counted down by 1 (step ST6). In step ST6, only the countdown is performed, and the display of the segment display unit 21 is not changed. Then, it is determined by the control part 30 whether cooking remaining time is 0 (step ST7). If the remaining cooking time is not 0 (No in step ST7), the process returns to step ST2. On the other hand, when the remaining cooking time is 0 (Yes in step ST7), the display on the display unit 3 ends.

  Next, the operation of the heating cooker 1 according to the first embodiment will be described. The time display means 34 displays the remaining cooking time converted into time units on the segment display unit 21 with a maximum of two digits. For this reason, if the segment display part 21 can display a two-digit number, it is enough to display the cooking remaining time. Therefore, in the heating cooker 1, the segment display part 21 which displays a number more than three digits becomes unnecessary. Therefore, the heating cooker 1 can suppress the increase in cost while being able to recognize the remaining cooking time even when the remaining cooking time exceeds 100 minutes.

  Here, the cooking remaining time is converted into a time unit using the above formula (1). From equation (1), 100 minutes to 120 minutes is converted to 2 hours, and 121 minutes to 180 minutes is converted to 3 hours. Thus, the converted cooking remaining time is slightly different from the actual cooking remaining time. However, when the remaining cooking time is 100 minutes or more, the urgency of quickly preparing other ingredients is low. For this reason, even if the converted remaining cooking time is slightly different from the actual remaining cooking time, the convenience for the user is not impaired.

  An approximately display unit 23 is provided between the segment display unit 21 and the hour digit segment display unit 22. For this reason, the cooking remaining time displayed on the segment display unit 21 is displayed immediately after the character “about”. Therefore, the visibility of the cooking remaining time is improved.

  When the remaining cooking time is displayed with three digits as in the conventional case, the hundreds digit is displayed on the hour digit segment display unit 22 and is positioned before the character “about”. In order to solve this problem, if it is attempted to display the characters “about” in front of the hour digit segment display unit 22, the cost increases accordingly. Furthermore, since the colon display portion 26 is provided, a gap is generated between the 100th place and the 10th place. In addition, if it is going to display the character "about" for every digit, it will cost that much. Further, conventionally, when the display is difficult to see, the remaining cooking time is not displayed. In this Embodiment 1, since the time display means 34 displays the cooking remaining time converted into the time unit on the segment display part 21 by a maximum of two digits, such a problem does not arise.

  Moreover, the time display means 34 erase | eliminates the display of the cooking remaining time displayed on the segment display part 21, after predetermined time passes since cooking of the cooking appliance main body 2 was started. Thereby, when display of the cooking remaining time is unnecessary, extra power is not consumed and it contributes to energy saving. Furthermore, the time display means 34 displays the remaining cooking time on the segment display unit 21 when the display operation unit 5 is operated. Thereby, when display of the cooking remaining time is unnecessary, extra power is not consumed and it contributes to energy saving. Furthermore, the time display means 34 displays the remaining cooking time on the segment display unit 21 when it is detected by the person detection unit 14 that a person has approached the cooker body 2. Thereby, when display of the cooking remaining time is unnecessary, extra power is not consumed and it contributes to energy saving.
