The control means 22 has the time measuring means 21 of the present time, and by the input from the operating means 4, the temperature detecting means 7 and the power failure detecting means 5, the control means 22 performs the heating means 2, the display means 3 and the time measuring means in a predetermined procedure. 21 is controlled.

  About the rice cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below using FIG. 3, FIG.

  When it is detected in step S01 that power from the commercial power source is supplied by the power failure detection means 5, the control means 22 proceeds to step S02 and is determined in advance by input from the operation means 4 and the temperature detection means 7. In accordance with the above procedure, the time measuring means 21, the heating means 2 and the display means 3 are controlled to perform various settings, rice cooking, heat insulation, etc., and the current time and state by the time measuring means 21 at that time are displayed on the display means 3.

  Further, when the power failure detection means 5 detects that the power from the commercial power supply is not supplied in step S01, the control means 22 proceeds to step S03 and usually operates a plurality of switches of the operation means 4 simultaneously. When the operation is not performed in a predetermined procedure that is not performed, the process proceeds to step S04, step S07, step S08, and step S05, the heating unit 2 is stopped, and the current time measurement by the time measurement unit 21 is continued and displayed. The means 3 displays the current time measured by the time measuring means 21 and that there is no power supply from the commercial power source.

  Further, when the power failure detection means 5 detects that the power from the commercial power supply is not supplied in step S01, the control means 22 proceeds to step S03 and usually operates a plurality of switches of the operation means 4 simultaneously. When operating in a predetermined procedure that is not performed in use, the process proceeds to step S04, step S09, and step S06, the heating unit 2 is stopped, the current time measurement by the time measuring unit 21 is also stopped, and the display unit 3 The display is not performed, and after that, when it is detected in step S11 that power is supplied from the commercial power source by the power failure detection means 5, the process proceeds to step S13 and step S12, and the current time by the time measuring means 21 is displayed. Timekeeping is resumed and display by the display means 3 is performed.

  As described above, according to the present embodiment, there is no supply of power from the commercial power source when operating in a predetermined procedure that is not performed in normal use, such as operating a plurality of switches of the operating means 4 simultaneously. If the current time is not measured by the timekeeping means and the display means is not displayed, the backup power supply is further depleted, and power is not supplied from the commercial power supply if the operation is not performed according to the prescribed procedure. Since the current time is measured by the time measuring means and the display means is displayed, the current time is stopped when the user does not intend to supply power from the commercial power source. By not displaying, the consumption of the backup power source can be suppressed, and the display and the current time can be prioritized. In particular, if the backup power supply is a primary battery and the replacement is not easy for the user, the user can actually use the product to operate the backup power It is possible to suppress the consumption of the backup power supply until it is required.

In addition, only when an operation is performed in accordance with a predetermined procedure every time a state where power is supplied from a state where there is no power supply from the commercial power source, and when there is no subsequent power supply from the commercial power source, It is possible not to display the time and display by the display means. In this case, the backup power supply is turned off by performing a predetermined operation at the time of shipment from the factory so that the current time is not measured by the time measurement means and the display means is not displayed. After the consumption is further suppressed and the user supplies power from the commercial power source, the current time is counted by the time measuring means even when power is not supplied from the commercial power source unless the operation is performed according to a predetermined procedure. By displaying on the display means, it is possible to further reduce the consumption of the backup power source from the factory shipment until the user uses it, and the user can unintentionally trade. Can be prevented so not to display by the time counting and display means of the current time according to the timer means when power is not supplied from the power source.

(Embodiment 3)
FIG. 5 is a block diagram of a rice cooker according to the third embodiment of the present invention, and FIG. 6 shows a flowchart of the rice cooker according to the third embodiment of the present invention.

  5 and 6, the same reference numerals as those in FIGS. 1 to 4 are the same, and detailed description thereof is omitted. The control means 31 controls the heating means 2, the display means 3, and the time measuring means 21 in accordance with predetermined procedures based on inputs from the operation means 4, the temperature detection means 7, and the power failure detection means 5.

  About the rice cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below using FIG. 5, FIG.

  When it is detected in step S01 that power from the commercial power source is supplied by the power failure detection means 5, the control means 31 proceeds to step S02 and is determined in advance by input from the operation means 4 and the temperature detection means 7. In accordance with the above procedure, the time measuring means 21, the heating means 2 and the display means 3 are controlled to perform various settings, rice cooking, heat insulation, etc., and the current time and state by the time measuring means 21 at that time are displayed on the display means 3.

  Further, when the power failure detection means 5 detects that no power is supplied from the commercial power source in step S01, the control means 31 proceeds to step S03 and normally operates a plurality of switches of the operation means 4 at the same time. When the operation is not performed in a predetermined procedure that is not performed, the process proceeds to step S04, step S07, step S08, and step S05, the heating unit 2 is stopped, and the current time measurement by the time measurement unit 21 is continued and displayed. The means 3 displays the current time measured by the time measuring means 21 and that there is no power supply from the commercial power source.

Further, when the power failure detection means 5 detects that no power is supplied from the commercial power source in step S01, the control means 31 proceeds to step S03 and normally operates a plurality of switches of the operation means 4 at the same time. When operating in a predetermined procedure that is not performed in use, the process proceeds to step S04, step S09, and step S06, the heating unit 2 is stopped, the current time measurement by the time measuring unit 21 is also stopped, and the display unit 3 The display is not performed, and after that, when it is detected in step S11 that power is supplied from the commercial power source by the power failure detection means 5, the process proceeds to step S13 and step S12, and the current time by the time measuring means 21 is displayed. Timekeeping is resumed and display by the display means 3 is performed.

  After that, when the current time is set by the operation unit 4 in step S21, the process proceeds to step S27 even if the power failure detection unit 5 detects again that no power is supplied from the commercial power source in step S22. The clocking of the current time by the clocking means 21 is not stopped.

  On the other hand, if the current time is not set by the operation means 4 in step S21 and if no power is supplied from the commercial power source by the power failure detection means 5 again in step S22, the process proceeds to steps S29 and S26. Then, the time of the current time by the time measuring means 21 is stopped without displaying by the display means 3.

  As described above, according to the present embodiment, there is no supply of power from the commercial power source when operating in a predetermined procedure that is not performed in normal use, such as operating a plurality of switches of the operating means 4 simultaneously. If the current time is not measured by the timekeeping means and the display means is not displayed, the backup power supply is further depleted, and power is not supplied from the commercial power supply if the operation is not performed according to the prescribed procedure. Since the current time is measured by the time measuring means and the display means is displayed, the current time is stopped when the user does not intend to supply power from the commercial power source. By not displaying, the consumption of the backup power source can be suppressed, and the display and the current time can be prioritized.

  In addition, when the current time is stopped and the power supply is detected from the state where there is no power supply from the commercial power supply, the current time by the time measuring means is clearly different from the original current time. Therefore, the user who needs the current time will set the current time using the operating means, and the user who needs the current time needs the current time to set the clock without being aware of the specific operation. If it is a user, it is possible not to stop the time measurement of the current time by the time measuring means when there is no power supply from the commercial power supply unintentionally by means of normal operation, and at the factory or store, When power is supplied from a commercial power source in the operation check, the original state can be obtained without performing a specific operation again.

  In the present embodiment, there is no particular limitation on the display when a state in which power is supplied is detected from a state in which power is not supplied from a commercial power supply in a state in which the time measurement of the current time is stopped. Obviously, it may be displayed so that it is understood that is not set.

  As described above, the rice cooker according to the present invention can suppress consumption of the backup power source without inadvertently turning off the display even in the absence of power supply from the commercial power source. It can be applied not only for use but also for business rice cookers.
