Controls the energization of the first and second heating hand throws 8 and 16 as shown in the flowchart of FIG. That is, when the steam button 23 is turned on (step 1), it is determined whether or not the first heating hand throw 8 is in the energized state at that time (step 2), and the first heating hand throw 8 is turned on. If it is in the state, the energization of the first heating hand throw 8 is temporarily stopped (step 3), the energization of the second heating hand throw 16 is started (step 4), and the steam can be generated (step 3). Step 5). If it is determined in step 2 that the first heating hand throw 8 is not in the energized state, the operation proceeds to step 4, and immediately the second heating hand throw 16 is energized so that steam can be generated. Thereafter, when the steam button is turned off (step 6), it is determined whether or not the first heating hand throw 8 is in the energization temporary stop state at that time (step 7), and the first heating hand throw 8 is turned on. If it is determined that the first heating manual throw 8 is in the current stopping state in step 7, the process is terminated, and the power supply to the first heating manual throw 8 is restarted ( Step 8), first and second heating throws 8, 16
The energization switching control process is completed. In this way, simultaneous energization of the first heating hand throw 8 and the second heating hand throw 16 is prevented.
