DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 7 denotes a warm air unit having a heater and a blower built therein, and a bag-shaped container 9 through a communication port 8.
It is configured integrally with. Further, a mounting band 11 is sewn on the lower surface of the bag-shaped container 9, and the mounting band 11 is turned around the bed mattress 12, and the planar fasteners 13 at the ends of the mounting band 11 are used to slam each other so that the communication port is closed. The bag-shaped container 9 is fixed to the bedclothes or the mattress at a predetermined position where 8 is the bedside. About 150 air holes 10 of 3 mm in diameter were provided on the upper surface of the bag-shaped container 9. Density on the foot side was 3.0 / 100 cm ² , density on the chest side was 1.5 / 100c.
m ² , 0.5 near the joint with the mounting band 11/1
It is distributed at 00 cm ² . Further, a bed pad 14 on which a linear quilting process is performed in the longitudinal direction, which is the longitudinal direction, is placed on the bag-shaped container 9 to form a bedding.

As shown in FIG. 2, the sectional structure on the foot side of the bed pad 14 is such that the cloth 1 is formed on both sides of the sheet-like cotton material 15.
After 6 layers are quilted and sewn together, a structural material 17 made of foamed polyethylene is sewn on the back side with a cloth 18, and 19 is a peripheral edge cloth.

FIG. 3 is a cross-sectional view of the embodiment when it is used. The outer peripheral portions of the upper cloth 20 and the lower cloth 21 provided with the ventilation holes 10 are adhered to each other to form the bag-shaped container 9, The attachment band 11 is sewn on the center of the lower cloth 21 to be integrally formed. The width dimension of the bag-shaped container 9 is smaller than the width dimension of the bed pad 14, and the bag-shaped container 9 is arranged between the structural members 17.

The operation of the above configuration will be described. The warm air discharged from the warm air unit 7 passes through the communication port 8 and is blown out into the bag-shaped container 9. As the pressure inside the bag increases, the bag-shaped container 9 swells and a hot air passage can be secured up to the foot side, and the hot air is blown out uniformly from the ventilation hole 10. Operating static pressure when standard sheets and comforters are applied is about 20 mmAq.
Uniform futon drying can be realized with the thin and compact type warm air unit 7 that can be attached to the side surface of the. This is the internal pressure distribution of the bag-shaped container 9 according to the bag shape at the time of operation determined by the mounting structure and the distance from the warm air unit 7, and the distribution density of the ventilation holes 10 is set accordingly. This is because it can be made uniform from the chest to the feet. In addition, the temperature distribution was higher on the foot side where the vent holes 10 were more open, which was a comfortable distribution of head cold foot heat. Further, unlike the conventional method utilizing the air permeability of the cloth, the vent hole 10 having a diameter of 3 mm is provided so that clogging does not occur.

When the bed is made, as shown in FIGS. 2 and 3, the convex shape of the structural material 17 serves as a fulcrum.
A blanket or upper sheets act so as not to press the bag-shaped container 9 on the foot side where the internal pressure becomes low, and a warm air passage is secured up to the foot side where making is strong. The cross-sectional shape of the structural material 17 is □ 30 mm, and 6 from the foot side short side.
Although it was arranged with a length of 00 mm, the same blowing performance of warm air as when bed making was not performed was confirmed. The rubber hardness of the structural member 17 was set to about 60 °, but since it is located on the foot side of the foot, it does not interfere with sleeping.
Does not spoil the comfort of sleep. Further, since the structural material 17 is provided on the lower surface of the bed pad 14, there is an effect that the position of the bag-shaped container 9 does not deviate from the predetermined position of the mattress.

Further, as shown in FIG. 3, by mounting the mounting band 11 inside the outer periphery of the lower cloth 21, the bag-shaped container 9 easily bulges upward due to the internal pressure during a driving operation, Pressure loss can be significantly reduced. That is, the stronger the attachment of the attachment band 11 to the mattress, the smaller the swelling of the bag of the bag-shaped container 9 during operation, but the attachment band 11 is sewn slightly inside the outer periphery of the lower cloth 21. By joining, a sufficient bulge can be secured, and at the same time, firm attachment to the bed mattress becomes possible. Even if the upper cloth 20 is made larger than the lower cloth 21 and the outer peripheral portions thereof are joined, the same effect can be obtained, but the joining process is extremely difficult, and
The wrinkles and sagging of the top cloth make it uncomfortable at bedtime.

Since the bed pad 14 is a linear quilt in the longitudinal direction in the longitudinal direction, the bed pad 14 can easily follow the bulge of the bag-shaped container 9 and is effective in reducing the pressure loss during the driving operation.

In the above-mentioned embodiment, the combination with the bed mattress has been described, but the same effect can be obtained even in combination with the mattress.

[0019]

As is apparent from the above embodiments, according to the present invention, a warm air unit including a blower and a heater,
A bag-shaped container that blows out warm air from a plurality of ventilation holes provided on the surface by blowing air from the warm-air unit, and a mounting means that lays the bag-shaped container on a bedding or a bed mattress, and the bag-shaped container is Since the upper surface member provided with the ventilation hole and the lower surface member are joined at the outer peripheral portion and the mounting means is joined to the lower surface member inside the joint, the following effects are obtained. Is what you get. 1. Since it has a bag-shaped container attachment means, it is not unevenly inserted between the beddings, and there is no unevenness in drying. Moreover, since the attachment means is joined to the inside of the outer peripheral portion of the lower surface member constituting the bag-shaped container, even if the bag-shaped container is firmly mounted, the air passage pressure loss inside the bag-shaped container does not rise, and uniform drying can be achieved up to the end. .. 2. When the bag-like container is not in operation, it has a thin structure and can be dried uniformly, so that it does not impair the comfort of bedding. 3. Since the bag-shaped container is not clogged and there is no need to wash the bag-shaped container, it is easy to use and can be used continuously as installed. 4. Since the opening ratio per unit area of the ventilation hole is changed depending on the location, the internal distribution is controlled, and uniform drying can be performed up to the edge.
