Further, the heater 11 is provided with various sensors including a non-flammability detection sensor 17 that detects non-flammability of the burner 13, and an ignition electric power [!] for igniting the burner 13. 18 are arranged. The solenoid valves 14, 15, the proportional valve 16, the non-flammability detection sensor 17, the ignition power supply 8ii18, etc. are connected to the control circuit 2, and the control circuit 2 operates according to the settings of the operating section 3 as shown in FIG. , to control the fan heater 1 into various operating states. The control circuit 2 includes a timer section 4 that can select between an on mode in which the fan heater 1 is started at a preset time and an off mode in which the fan heater 1 is stopped at a preset time. It has a mode selection section 5 that selects whether to put it in on mode or off mode. The control circuit 2 is supplied with commercial power AC. The operation section 3 includes an operation switch SW7 for selecting start and stop of the fan heater 1, a timer switch SW2 for starting a timer section 4 provided in the control circuit 2, a time setting section 21 for setting a set time in the timer section 4, A time display section 22 that displays the set time and current time, a temperature setting section 23 that sets the desired room temperature,
It includes a temperature display section 24 that displays the set temperature and the current room temperature. Incidentally, the timer section 4 and mode selection section 5 in the control circuit 2 operate as shown in FIG. 2 in response to the operation of the operation switch SW1 and the timer switch SW2. That is, as explained in the section of the prior art, the order of operation of the operation switch SW and the timer switch SW2 is such that when the operation switch SW1 is operated to operate the fan heater 1, the timer section 4 is started. When operating timer switch SW 2 and when operating timer switch SW
There are two possible sequences: when the timer unit 4 is operated by repeatedly operating W2, and when the operation switch SW1 is operated so that the fan heater 1 is started. The operation in the former case is shown in the right half of the second section, and the operation in the latter case is shown in the left half of FIG. First, the former case will be explained. Operation switch SW
When fan heater 1 is turned on, fan heater 1 starts. When the timer switch SW2 is turned on while the fan heater 1 is in operation, the mode selection section 5 sets the timer section 4 to the off mode and starts the timer section 4. At this time, the fan heater 1 is kept in continuous operation. When the set time of the timer unit 4 comes while the fan heater 1 is in operation, the fan heater 1 stops because the timer unit 4 is in the off mode. Further, when the operation switch SW1 is turned off before the set time, the mode selection section 5 returns the timer section 4 to the on mode and stops the fan heater 1. At this time, the timer section 4 continues to operate, and when the set time comes, the fan heater 1 is operated. In this way, when the fan heater 1 is in operation, the timer switch s
Even if w2 is turned on, the fan heater 1 continues to operate, and at this time, even if the timer section 4 is set to the on mode, the off mode is forcibly selected. Furthermore, if the fan heater 1 is stopped during the time limit of the timer section 4, the timer section 4 returns to the on mode. According to the above operation, the fan heater 1 will not be stopped by operating the timer switch sw2. Furthermore, when the fan heater 1 and the timer section 4 are operating at the same time, the timer section 4 is set to the off mode, so that a feeling of use that matches the user's senses can be obtained. . On the other hand, when the operation order of the operation switch SW1 and the timer switch SW2 is the latter mentioned above, the operation is as follows. That is, when the timer switch SW2 is turned on, the timer section 4 is set to the on mode and started. If the operation switch SW1 is not turned on during the time limit of the timer section 4, the fan heater 1 will start at the set time. Operation switch S is pressed before the set time of timer section 4.
When W1 is turned on, the mode selection section 5 sets the timer section 4 to off mode and starts the fan heater 1. At this time, the timer section 4 continues its operation. When the set time of the timer unit 4 comes while the fan heater 1 is in operation, the fan heater 1 stops because the timer unit 4 is in the off mode. Also, if the operation switch SW1 is turned off before the set time, the mode selection section 5
Then, the timer section 4 is returned to the on mode, and the fan heater 1 is stopped. Since the timer section 4 continues its operation, the fan heater 1 starts at the set time. In this way, when the timer section 4 is in a time limit, the operation switch SW1
When turned on, the fan heater 1 starts while the timer section 4 continues to operate. Further, at this time, even if the timer unit 4 is set to the on mode, it is forcibly switched to the off mode. If the fan heater l is stopped during the time limit of the timer section 4,
The timer section 4 returns to the on mode. According to the above operation, the timer section 4 is not reset even if the operation switch SW is repeatedly operated while the timer section 4 is in operation. In short, when the fan heater 1 and the timer section 4 are operating at the same time, the timer section 4 operates in off mode,
When the timer section 4 is operating while the fan heater 1 is stopped, the timer section 4 operates in the on mode.
