Operation was required.

When the timer key 4 is operated and the signal is received at the same time as the timer key 4 is operated to enter a timer operation state, if the timer key 4 is erroneously pressed during the time setting, combustion is immediately performed at that time. There was also a problem of inconvenience such as stopping to enter the timer operation state and not accepting resetting.

[0005] Further, such a timer operation control device is provided with a clock display unit 5. Even if the timer time has already been set, the clock display unit 5 is only required to press the timer key 4. The set timer time is not displayed, and the user has to press the timer adjustment key 1 to check the timer time. For this reason, there is a problem that the usability is poor in this respect.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and aims at facilitating setting of a timer operation and facilitating confirmation of a timer time, thereby improving usability.

Is output, a central control unit that switches to a timer operation state, and a second timer unit that starts a counting operation from the time when the central control unit switches to the timer operation state, wherein the central control unit has a second timer unit. While the count operation is being performed, the timer setting correction input by the time setting key is received, and the central control unit displays the timer time on the display unit while the second timer unit is performing the count operation. It is configured to continue to display the current time after counting up.

According to the present invention, when the timer key is operated, the timer time can be automatically adjusted. If the timer time is adjusted and it is not necessary to adjust the timer time, the operation is not performed. In addition, if the timer time is not set, the timer time is set, and after the setting is completed, the timer operation is automatically started without any operation, and the operation becomes very simple. In addition, the timer time can be checked simply by pressing the timer key, and even after entering the timer operation state, the timer time setting is accepted while the second timer section is counting time. If the second timer counts up, the current time is automatically displayed and the time change is not accepted. Even if there is a mistake in setting the timer operation time, the time can be changed immediately. There is no need to start over from the first operation, and the usability is improved.
