Therefore, it is not necessary to set the timer time each time the operation switch is turned on, which is convenient.

[0003]

However, although there is a timer setting device for such a combustion device in the related art, the conventional device has a short remaining time of the timer during combustion, and when the user wants to burn a little more, the set time is set longer. When changed, the changed time is memorized and the changed time is set when the operation switch is turned on next time.

Explaining with a concrete example, it is assumed that the user usually uses a timer set time of 50 minutes for boiling a bath and sets the timer to 50 minutes. If I want to burn more when the remaining time is 5 minutes during combustion and change the timer setting time to 10 minutes, that 10 minutes is stored as the timer setting time, and the first timer setting time when the next operation switch is turned on is 10 minutes. It becomes a minute. With this, the bath heating time is insufficient, and the timer setting time is set to 50 again.

Next, the operation of the embodiment of the present invention will be described with reference to FIGS. FIG. 3 is a transition diagram for explaining the mode of hot water supply operation. First, when the power switch is off, the stop mode is set (S1), and when the power switch 11 is turned on, the standby mode is set (S2). When the ignition switch 12 is turned on in this state, ignition is performed and the combustion mode is set (S3). When the fire extinguishing switch 13 is turned on in the combustion mode or when the timer means counts the timer set time and the timer is up, the mode is shifted to the fire extinguishing mode and the combustion is stopped (S4). Then, after shifting to the fire extinguishing mode, it shifts to the standby mode after a lapse of a predetermined time (S
2) If the power switch is further turned off, the mode is changed to the stop mode, and if the ignition switch is turned on, the mode is changed to the combustion mode.

Next, the flow chart shown in FIG. 4 shows the operation relating to the timer setting. If there is an input from the timer setting input means 14 (S11), the mode determination means 32 determines which mode shown in FIG. 3 (S1).
2). Here, the standby mode is a permission mode which allows the contents of the timer storage means 41 to be changed, and the combustion mode and the fire extinguishing mode are the prohibition modes which prohibit the change of the timer storage means 41. is there. Therefore, when the mode determining means 32 determines that the standby mode is the permit mode (S1).
3) The current timer is changed to the input timer time (S14), and the time stored by the timer management control means 34 in the timer storage means 41 is changed to the input timer set time (S15). Then, in order to notify that the change storage in the timer storage means 41 is completed, the timer display means 21 is blinked for a predetermined time (S16). This is convenient because the changed and stored timer setting time is initialized when the power switch is turned on next time.

When it is determined in step S13 that the combustion mode or the extinguishing mode is the prohibit mode, the timer means 33 is operated at the timer setting time input by the timer setting input means 14. Then, the timer setting time is not changed and stored in the timer storage means 41 (S17). Therefore, in the prohibit mode, the timer time is only temporarily changed to extend or shorten the timer time.
When the operation switch 11 is turned on next time, the timer setting time stored in the timer storage means 41 as usual is initialized, which is convenient.

In the above embodiment, the permit mode is the standby mode and the prohibit mode is the combustion mode and the fire extinguishing mode, but the permit mode and the prohibit mode are corresponded. The mode can be set arbitrarily and may be other than this. For example, the fire extinguishing mode may be the permit mode instead of the prohibit mode.

[0020]

As described above, in the timer setting device of the present invention, the mode which may be a temporary change of the timer is prohibited, and the change storage of the timer setting time stored in the timer storage means is performed. Since the permission mode for permitting is provided and the content of the timer storage means is changed and stored only when the mode discriminating means discriminates the permission mode, when the remaining time of the timer is short during combustion. Even if the timer setting time is extended and changed for a few minutes, this is a temporary change in the timing of the timer means, and when the operation switch is turned on next time, it is stored in the normal timer storage means. The effect is that the preset timer setting time can be initialized.

Further, the contents of the timer storage means can be conveniently changed and stored by operating the timer setting input means in the permission mode.
