[Problems to be Solved by the Invention] In recent years, the number of users who dry the futon (9) before going to bed and come to the floor has increased. According to sleep physiology, the bed temperature varies slightly from person to person, but is 5 ° C to 10 ° C below body temperature (about 36 ° C).
It is said that temperatures as low as ℃ can sleep comfortably. To obtain this bed temperature with a conventional futon dryer, the room temperature must be 26
When the temperature is between about 30 ° C. and 31 ° C., the above-mentioned operation by “automatic air blowing” is suitable for the condition, but when the temperature is other than room temperature, it is difficult to satisfy the condition. For example, when the room temperature is 10 ° C. or 20 ° C., as shown in FIG. 7, the air temperature after the futon drying is completed becomes almost the same as the room temperature, so that a comfortable bed temperature cannot be obtained. When the futon dryer main body (1) was operated with "warm air" for only futon drying, the temperature characteristics were as shown in FIG. 6, and the futon dryer was not immediately put on the floor. In such a case, in order to remove the hot air from the futon (9), the futon (9)
There are various problems in that there is an operation of lifting or removing hot air.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a futon dryer capable of providing a bed temperature according to a user's request without being affected by room temperature.
