Further, the heating conditioner 1 may be provided with a weight check for detecting the weight of the rice cooking amount or the like. Measuring unit (not shown). In this case, the calculation means 31 calculates the conditioning remaining time based on the detection result of the weight detecting unit.

The determination means 32 determines whether or not the conditioning remaining time is 100 minutes or longer.

The conversion means 33 is a case where the determination means 32 determines that the remaining time of the conditioning is 100 minutes or longer, and converts the remaining time of the conditioning from the minute unit to the hour unit. Specifically, the conversion means 33 divides the value obtained by subtracting 1 from the conditioning remaining time by 60, and adds 1 to convert the remaining time of the conditioning from the minute unit to the hour unit. That is, the conversion means 33 converts the conditioning remaining time from the minute unit to the hour unit by the following mathematical formula (1).

The remaining time of conditioning of the hour unit = (the remaining time of the conditioning of the minute unit -1) / 60 +1...(1)

The hour display means 34 causes the seven-segment display unit 21 to display the remaining time of the adjustment in which the conversion means 33 is converted into the hour unit by the maximum two-digit number. Further, the hour display means 34 sets the interval at which the remaining time of the conditioning displayed on the seven-segment display unit 21 is reduced to a constant value, regardless of the cooking amount, after the step of the conditioning of the conditioner body 2 is shifted to 焖.

The remaining time of conditioning is in the case of cooking a 1 liter electric cooker, and it is displayed by cooking 0.54 liters. In the case where the amount of rice is greater than 0.54 liters, since the conditioning time is longer than cooking 0.54 liters, the actual conditioning remaining time is longer than the remaining conditioning time shown. Also, in the case where the amount of rice is less than 0.54 liters, since the conditioning time is shorter than 0.54 liters of cooking, the actual conditioning remaining time is shorter than the remaining conditioning time shown.

Here, when the conditioning moves to the step of 焖, the remaining time of conditioning is not On the amount of cooking, they all become equal. That is, when the conditioning moves to the step of 焖, the actual conditioning remaining time becomes true. Therefore, in the step of 焖, the interval of reduction of the displayed conditioning time is changed so that the time at which the conditioning ends is actually coincident with the displayed remaining time of the conditioning. The hour display means 34 sets the interval at which the remaining time for conditioning displayed on the seven-segment display unit 21 is reduced to a constant value, regardless of the amount of cooking, after the step of the conditioning of the conditioner body 2 is shifted to 焖. Thereby, the user is prevented from being inconsistent with the actual time due to the decrease in the remaining time of the displayed conditioning.

Further, the hour display means 34 causes the display of the remaining time of the conditioning displayed on the seven-segment display unit 21 to disappear after the conditioner body 2 starts conditioning and after a predetermined period of time has elapsed. Further, the hour display means 34 causes the seven-segment display unit 21 to display the remaining time of conditioning when the display operation unit 5 is operated. Further, the hour display means 34 causes the seven-segment display unit 21 to display the remaining time of conditioning when the person detecting unit 14 detects that the person approaches the processor body 2.

Here, the notification unit 12 notifies the changed content when the remaining time for conditioning displayed on the seven-segment display unit 21 is changed from the hour unit to the minute unit. When the remaining time for conditioning displayed on the seven-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 changed content. When the notification unit 12 is a speaker, the notification unit 12 changes the remaining time of the conditioning from the hour unit to the minute unit by voice. Thereby, the user can know that the hour unit is changed to the minute unit.

Fig. 7 and Fig. 8 are views showing an example of the notification unit 12 according to the first embodiment of the present invention. As shown in FIGS. 7 and 8, the notification unit 12 is not limited to a speaker, and may be realized by a display pattern of the seven-segment display unit 21. control The system 30 is in the seven-segment display unit 21, and first, the display of one of the seven segments disappears. Next, the control unit 30 displays the seven segments and causes the display of the seven segments adjacent to the seven segments to disappear. By repeating, in the seven-segment display portion 21, the portion where the display of the seven segments disappears is rotated.

Fig. 9 is a flow chart showing the operation of the heating conditioner 1 according to the first embodiment of the present invention. Next, the operation of the heating conditioner 1 of the first embodiment will be described. As shown in FIG. 9, when the display of the display unit 3 is started, first, the remaining time for conditioning is calculated by the calculation means 31 (step ST1). Next, the determination means 32 determines whether or not the conditioning remaining time is 100 minutes or longer (step ST2).

In the case where it is judged that the remaining time of the conditioning is less than 100 minutes (NO in step ST2), the hour display means 34, the remaining time of the conditioning is displayed in the seven-segment display portion 21 at the maximum two digits while still being the minute unit ( Step ST4). Then, the process moves to step ST5. On the other hand, when it is judged that the conditioning remaining time is 100 minutes or more (YES in step ST2), the conditioning remaining time is converted from the minute unit to the hour unit by the conversion means 33. Specifically, the mathematical formula (1) is used for conversion. Next, the hourly display means 34 displays the remaining time of the conditioning converted into the hour unit in the seven-segment display unit 21 by the maximum two digits (step ST3). Then, the process moves to step ST5.

In step ST5, the borrowing control unit 30 determines whether or not one minute has elapsed. In the case where one minute has not elapsed (NO in step ST5), the process returns to step ST2. In contrast, in the case where one minute has elapsed (YES in step ST5), the conditioning remaining time is decremented by one (step ST6). Further, in step ST6, only one is decremented by 1, and the display of the seven-segment display portion 21 is unchanged. Then, the borrowing control unit 30 determines whether or not the conditioning remaining time is 0 (step ST7). In the case where the remaining time of the conditioning is not 0 (in the step ST7 is NO), and returns to step ST2. On the other hand, when the conditioning remaining time is 0 (YES in step ST7), the display on the display unit 3 ends.

Next, the action of the heating conditioner 1 of the first embodiment will be described. The hour display means 34 causes the seven-segment display unit 21 to display the remaining time of conditioning which is converted into hour units by the maximum two-digit number. Therefore, the seven-segment display unit 21 is sufficient to display the remaining number of times as long as the number of two digits can be displayed. Therefore, in the heating of the conditioner 1, it is not necessary to display the seven-segment display portion 21 of three or more digits. Therefore, the heating conditioner 1 can suppress the increase in cost while knowing the remaining time of conditioning even if the remaining time of conditioning is more than 100 minutes.

Here, the conditioning remaining time is such that the mathematical formula (1) is converted into an hour unit. According to the mathematical formula (1), it is converted into 2 hours from 100 minutes to 120 minutes, and is converted into 3 hours from 121 minutes to 180 minutes. In this way, the converted conditioning remaining time is slightly different from the actual conditioning remaining time. However, when the remaining time of conditioning is 100 minutes or more, the urgency of preparing other foods and the like is low. Therefore, even if the converted conditioning remaining time is slightly different from the actual conditioning remaining time. The convenience of the user will not be impaired.

Further, the display unit 23 is disposed between the seven-segment display unit 21 and the hour-digit seven-segment display unit 22. Therefore, the remaining time of the conditioning displayed on the seven-segment display unit 21 is displayed after the text of "about". Therefore, the visibility of the remaining time of conditioning is improved.

In the case where the remaining time of the conditioning is displayed in three digits as in the past, the hundreds of digits is displayed in the hourly seven-segment display unit 22, and is located in front of the text of "about". Further, in order to solve this problem, if the character "about" is displayed in front of the hourly seven-segment display unit 22, the cost of the portion is increased. Further, since the colon display portion 26 is provided, a gap is generated between the hundredth and tenth positions. In addition, if you want to display the text "about" in the number of digits, the cost of this part is increased. Further, in the past, when the display was not good, the remaining time for conditioning was not displayed. In the first embodiment, the hour display means 34 does not cause such a problem because the seven-segment display unit 21 displays the remaining time of the conditioning converted into the hour unit by the maximum two-digit number.

Further, the hour display means 34 causes the display of the remaining time of the conditioning displayed on the seven-segment display unit 21 to disappear after the conditioner body 2 starts conditioning and after a predetermined period of time has elapsed. In this way, it is not necessary to display the remaining time of conditioning, and no additional power is wasted, which helps to save energy. Further, the hour display means 34 causes the seven-segment display unit 21 to display the remaining time of conditioning when the display operation unit 5 is operated. In this way, it is not necessary to display the remaining time of conditioning, and no additional power is wasted, which helps to save energy. Further, the hour display means 34 causes the seven-segment display unit 21 to display the remaining time of conditioning when the person detecting unit 14 detects that the person approaches the processor body 2. In this way, it is not necessary to display the remaining time of conditioning, and no additional power is wasted, which helps to save energy.
