On the other hand, in summer, the temperature (room temperature) and humidity are high, the futon is hot, and sweating during sleep is also sultry.

  The user can set the operating condition of the controller (not shown) according to the operating condition of whether to send warm air into the air-conditioning futon 1 or to enter room air depending on whether the temperature (room temperature) is low in winter or high temperature and humidity in summer. Use properly by etc.

  As an example, an operation of sending warm air from the warm air / air blowing unit body 8 into the air-conditioning futon 1 in winter will be described.

  First, as shown in FIG. 3, the tip of the connecting pipe 21 of the hot air / air blowing unit body 8 is connected to the insertion port 6 of the storage bag 5 stored in the air-conditioning futon 1, and the suction portion 14 is connected to the storage space 8a. The suction tube 11 is taken out and the suction tube 11 is extended, and the suction port 24 at the tip is installed at a position particularly far from the user's ear.

  Next, when an operating condition is input using a setting button or the like of the controller, the heater 17 is energized in accordance with the specified input operating condition, and the motor 27 is driven to rotate the blower fan 15. The temperature of the heater 17 and the air volume of the blower fan 15 are set to the user's favorite state by the controller in consideration of room temperature and the like.

  The air 13 sucked into the hot air / blower unit main body 8 from the intake pipe 9 connected to the tip of the suction pipe 11 by the rotation of the blower fan 15 passes through the heater 17 of the heater unit 18 from the outlet of the blower fan 15. It is heated while passing, and becomes warm air from the outlet 16 of the warm air / air blowing unit body 8 through the connecting pipe 21 and flows into the storage bag 5 from the insertion port 6 of the storage bag 5. And the air-conditioning futon 1 and the blanket, the comforter, etc. which were hung on the upper surface from the ventilation hole 7 of the upper surface of the storage bag 5 are warmed. As a result, the user can take a comfortable sleep. The temperature of the hot air is controlled so as not to exceed the temperature set by the temperature detecting element 19. When it is cold in winter, the warm air / air blowing unit body 8 is used as described above.

  On the other hand, when the temperature and humidity in summer are high, the controller prevents the heater unit 18 from being energized, sends the indoor air to the air-conditioning futon 1 through the hot air / air blowing unit main body 8, and changes the humidity and hot air inside the futon. Release outside. As a result, the user can take a comfortable sleep.
