However, in such a futon dryer, since the other end of the hose is only thinly formed in the vertical direction, warm air is distributed to every corner between the mattress or mattress (hereinafter abbreviated as mattress) and the comforter. It was not possible and uneven drying tended to occur. Further, since the other end of the hose is formed thin in the vertical direction, there is almost no space between the mattress and the comforter around the outlet of the other end of the hose. Therefore, since warm air is sent to the narrow gap between the mattress and the comforter, there is also a problem that it is difficult for the warm air to reach far.

An object of the present invention is to solve the above problems and to provide a futon dryer capable of sending warm air to every corner between a mattress and a comforter. Another object of the present invention is to provide a futon dryer capable of sending warm air to a long distance between a mattress and a comforter.

It has a plurality of outlets, and these outlets are configured so as to be spaced apart from each other toward the outlet side, and each of the outlets is at least at the outlet, outside the lateral direction. The outer dimension in the vertical direction is larger than the dimension, and the total area of the opening area of the blowout portion on the tip surface is smaller than the area of the tip surface .

Further, futon dryer according to claim 2 of the present invention, in claim 1, each of the outlet section, at least at its outlet, the inner dimensions of said longitudinal direction than the inner dimension of said lateral large It is supposed to be.

By configuring the futon dryer according to claim 1 of the present invention as described above, warm air is sent from a plurality of outlets so as to spread between the mattress and the comforter, so that the mattress and the comforter can be combined with each other. Warm air can be spread to every corner of the room to evenly dry it. Further, since the total area of the opening area of the blowing portion on the tip surface is smaller than the area of the tip surface, warm air can be squeezed and blown out by the blowing portion.

It should be noted that, at least at the outlet of each of the outlets, the outer dimension in the vertical direction is larger than the outer dimension in the horizontal direction, so that the comforter is at the height of the outlet in the vicinity of the outlet.
