Description

  The present invention relates to a heating cooker.

  Conventionally, there is known a gas heating cooker with a grill provided with a battery replacement time detecting means having a display for indicating that a battery replacement time for supplying power to a control unit and a display unit for controlling combustion has come. (For example, refer to Patent Document 1).

  In the conventional cooking device shown in Patent Document 1, a display that indicates that the battery replacement time has come is also used as a display that displays the ignition of the burner in the grill cabinet. When the ignition is displayed in a display mode different from the battery replacement time display, and when the battery replacement time occurs simultaneously with the ignition of the burner, the battery replacement time display is given priority.

Japanese Patent Laid-Open No. 10-2560

  In this conventional cooking device, when the ignition of the burner in the grill is displayed when the battery replacement time is displayed, for example, the display of the indicator blinks to indicate whether or not the battery replacement time is reached. Two display modes and two display modes indicating whether or not the burner in the grill is ignited are performed by one display device, and it is difficult for the user to understand the meaning of the display. In other words, since the user sees whether or not the burner in the grill is ignited only when the grill is used, it is difficult to remember the four display modes because the frequency of viewing is low and it is difficult to understand. .

  Also, the user looks only at the indication of whether or not the burner in the grill is ignited only when the grill is used, and does not pay attention to this indicator when the grill is not used. For this reason, even if the battery replacement time is displayed on the display, it is difficult to notice.

  The present invention has been made in view of these circumstances, and the object of the present invention is to allow the user to reliably grasp that it is time to replace the battery during operation. It is in providing the heating cooker which can replace | exchange reliably.

In order to solve the above-mentioned problem, the invention according to claim 1 includes a burner for heating an object to be heated, an operation unit for setting a heating condition in the burner, and an operation unit for commanding ignition / extinguishing of the burner. Based on the operation of the first operation unit, the second operation unit for allowing the operation of the first operation unit, and the operation of the second operation unit and the first operation unit, the combustion operation of the burner is performed. A control unit for controlling, a display unit for displaying that the operation of the first operation unit is permitted, a battery storage unit capable of storing a battery and supplying power to the control unit, Voltage monitoring means for monitoring whether or not the voltage of the battery has dropped below a predetermined voltage, and when the control unit is in a state where operation of the first operation unit is permitted, Displayed by the first display mode on the display unit Performed, when the voltage of the battery by the voltage monitoring means detects that the drop below the predetermined voltage, and operating one of the operating portion of the operating portion included in the first operation portion The display unit performs display in a second display mode different from the first display mode for a predetermined time .

   When the user operates the second operation unit that must be operated before the fire extinguishing of the burner of the heating cooker or the setting of the heating conditions, it is normal (here, the voltage of the battery drops below a predetermined voltage). If the display unit is displayed in the first display mode indicating that the operation of the first operation unit is permitted, a second different from the first display mode is displayed. In other words, when the display mode of the display unit is different from the usual display mode, it is possible to know the battery replacement time, and the user is sure to know that it is the battery replacement time. In this case, since the display unit for displaying the battery replacement time can also be used as another display unit (a display unit indicating that the operation of the first operation unit is permitted), the number of parts for display Therefore, a display unit that can appropriately display the battery replacement time to the user can be configured at low cost.

In addition , since the battery replacement time is notified when the user is near the cooking device, it is easy for the user to notice that it is the battery replacement time, and the display in the second display mode is not performed unless an operation is performed. In addition, since the display is turned off when a predetermined time elapses even if the display is performed, it is possible to suppress the battery replacement time display from being performed due to excessive battery consumption.

The invention according to claim 2 is characterized in that, in the invention according to claim 1 , the lighting display of the display unit is the first display mode, and the blinking display of the display unit is the second display mode. And

  Accordingly, the first display mode and the second display mode can be distinguished from each other by the lighting display and the flashing display, so that the cost is further reduced. Furthermore, since the blinking display can reduce power consumption as compared with the lighting display, it is possible to suppress the battery replacement time display from being impossible due to excessive battery consumption.

The invention according to claim 3 is the invention according to claim 1 or 2 , wherein the display color in the display section in the case of the second display mode is the same as that in the display section in the case of the first display mode. The display color is different from that of the display.

  As a result, the display mode is distinguished by the display color, so that the user can easily notice the change in the display mode compared to the case where the display mode is distinguished only by the blinking display and the lighting display, and the battery can be replaced more appropriately. Can tell you when.

  In the present invention, the user can surely grasp that it is time to replace the battery at the time of operation, and the user can reliably replace the battery.
