The damper 11 is provided so that the opening 10 may be provided in a part of 4 and the remainder may be closed. A timing motor 12 for switching the damper 11 to open or close is provided, and a cam 13 and a crank 14 are combined with the timing motor 12 so as to switch the damper 11 to open or closed.
[0013]
The damper 11 is provided at a position to close the humidification flow path 6 when the hot air is blown, and the damper 11 is switched to the open position when the humidified hot air is blown. It is provided to reduce. The humidifying part 5 is provided in communication with the lower part of the hot air flow path 4 in the vicinity of the air outlet 3, and during the hot air humidifying and humidifying operation, the damper 11 is maintained in a neutral state where the opening 10 is formed, and is directed to the air outlet 3. It forms and comprises so that the humidified airflow which flows through the humidification part 5 by the airflow of the flowing warm air flow path 4 may be induced.
[0014]
In the above configuration, during the hot air blowing operation, the damper 11 is switched to the closed position via the timing motor 12, the air sent from the blower 1 is heated by the heater 2, and the heated hot air is sent through the hot air passage 4. It blows out from the blower outlet 3, and will be heated.
[0015]
When the humidified hot air is blown, the damper 11 is switched to the open position via the timing motor 12, the opening 10 is formed in a part of the hot air flow path 4, and the damper 11 is in a neutral state so as to close the rest. , The air sent from the blower 1 is heated by the heater 2, the heated warm air is sent to the humidification channel 6, is humidified by the humidification unit 5 provided in the humidification channel 6, and is humidified from the outlet 3. Wind is blown out.

It blows out from the blower outlet 3 through the wind flow path 4. At this time, the humidifying part 5 is provided in the lower part in the vicinity of the air outlet 3, so that the warm air flowing through the warm air channel 4 attracts the humidified warm air stream from the humidifying channel 6 side and blows the air. The humidified warm air stream flowing through the path 6 is prevented from flowing back to the heater 2 side through the warm air channel 4.
[0017]
Next, at the time of humidifying air blowing operation, with the capacity of the heater 2 reduced, the damper 11 is switched to the open position via the timing motor 12, the opening 10 is formed in a part of the hot air flow path 4, and the rest is closed. The damper 11 is switched to the neutral state so that the air sent by the blower 1 is heated to a low temperature by the low-capacity heater 2, and the low-temperature warm air is sent to the humidifying channel 6. Humidified air is blown out from the blower outlet 3 after being humidified by the part 5.
[0018]
Further, a part of the low temperature air heated by the heater 2 has the damper 11 in a neutral state and an opening 10 is formed in a part of the hot air flow path 4, so that the low temperature air passes through the opening 10 and the hot air flow. It blows out from the blower outlet 3 through the path 4.
