The blower sheets 11 constitute the blower bag 14 by sewing the lower cloth 18 from the back to the bed surface of the upper cloth 17 that is sewn in a box shape so as to wrap the mattress 10 and the bed pad 16. The tubular air passage 1 that penetrates the notch in the center of the long side of the bag 14 and crosses the bed surface inside the blower bag 14.
5 are provided. The air passage 15 has a tubular shape with an entire circumference of 30 cm and a length of about 85 cm with respect to a bed width of 1 m, and only a tip portion thereof is sewn to the lower cloth 18 so as to have a sufficient expansion margin.

The warm air unit 7 is attached to the bedside by the load of the mattress or the like by inserting the flat plate portion of the L-shaped metal fitting 19 fixed to the back surface between the mattress 10 and the bed floor plate 20. Has been. In addition, the arrow in FIG. 1 is an inflow line of warm air.

FIG. 3 is a partially cutaway front view showing the arrangement of parts of the warm air unit 7, and FIG. 4 is a partially cutaway side view thereof. Reference numeral 21 is a deodorant antibacterial filter provided at the suction port on the lower surface of the warm air unit 7, and a sirocco fan 22 and a ceramic heater 24 held inside the wind tunnel 23 and the duct 9 are communicated therewith. is doing. A cavity is formed on the side of the wind tunnel 23 on the leeward side of the heater, and a thermosensitive portion of a thermostat 25 is provided inside the cavity.

Further, 27 is a power supply transformer of the DC fan motor 28, and 29 is a printed circuit board on which a rectifying circuit, a power supply fuse and a connector are arranged. Further, 30 is a mechanical rotary timer switch for controlling the energization time, and a knob 31 is provided in conjunction with it.

The knob 31 is in a space formed by a partition plate 32 formed from the back surface of the thin warm air unit 7 and an upper lid 33, and the lid 33 is opened as shown by a broken line in FIG. Operated. A mounting plate 34 is fixed to the back surface of the warm air unit 7 with a screw, and a claw of the mounting plate 34 can be fitted and fixed to an insertion hole of the L-shaped metal fitting 19. Further, the mounting plate 34 is provided with three sets of pawls at equal intervals, and can be mounted on mattresses having different thicknesses.

As shown by the chain double-dashed line in FIG. 3, the duct 9 has a flat, substantially elliptical shape whose cross section is thinner than that of the warm air unit 7, and an elastomer blow-molded product having a rubber hardness of about 75 °. It is joined so as to cover the wind tunnel 23 and can slide up and down in the unit. A lath net 26 is fitted at the tip of the wind tunnel 23 to protect foreign matter from entering.

Further, as shown in FIG. 5, the duct 9 is provided with a vertical portion 35 so as to penetrate the upper surface of the outer casing of the warm air unit 7, and the mattress 1
At the height of the upper surface of 0, it passes through a bent portion 36 that changes the blowing direction to the mattress side by approximately 90 °, and then reaches a horizontal portion 37 having a substantially elliptical cross-sectional shape, which is the same as the vertical portion 35, and an outlet 38 at the tip thereof. Is provided.

The blow-out port 38 is formed so that its tip is inclined with respect to the vertical direction and the upper part of the end face thereof projects in the blow-out direction, and a flange for preventing slipping out is also provided over the entire circumference.

Next, the operation of the structure of this embodiment will be described. First, the user opens the lid 33 and rotates the knob 31 from the OFF position by a predetermined angle according to the operating time.
In response to this, energization of the DC fan motor 28 and the ceramic heater 24 is started, and warm air is sent to the duct 9 by the sirocco fan 22. The warm air is sent into the air passage 15 through the duct 9, the air passage 15 swells as the pressure increases, and the warm air reaches the inside of the blower bag 14, and as the internal pressure increases, the warm air is blown into the bed. Warm air diffuses. Accordingly, not only the bed pad 16 and the mattress 10 but also the comforter on the blower sheet 11 can be uniformly dried.

Since the duct 9 is a molded product having the elasticity of rubber, even in the bent portion 36 where the load is most concentrated, the duct 9 is not crushed by the bedding load from above and a smooth air blow is possible.

Further, since the cross-sectional shape of the duct 9 is a flat elliptical shape that is thinner than the warm air unit 7, it looks thin when viewed from the side and the blower pressure loss can be reduced. Although the short inside diameter of this substantially elliptical shape was set to 25 mm, a sufficient internal pressure of air blow could be secured.

As the operation time elapses, the rotary timer switch 30 is reversed to the OFF position, and the drying operation is automatically stopped after a predetermined time. When the futon drying performance was investigated, it was about 60 at an internal pressure of 10 mmAq and an air volume of 0.5 m ³ / min.
When warm air of ℃ is blown, standard damp comforter (cotton 100% 5kg300
It was found that it can be made full in about 2 hours.

When the user sleeps on the blower sheet 11, the duct 9 has a flat elliptical cross section, and the upper end surface of the blow-out port 38 has an eaves-like shape in the blowing direction. Since it is protruding, the tip of the horizontal portion 37, which is often touched by the human body, is easily crushed by the human body load from above, and the feeling of foreign matter can be alleviated.

Furthermore, 60 kg relative to the horizontal portion 37
Although a trampling endurance test was carried out about 10,000 times under the load, since the upper part of the end face of the blowout port 38 protrudes in an eaves-like shape in the blowing direction, the tip end is bent as a whole and cracks such as parting parts are also generated. I couldn't see it at all, so there was no problem.

When the blower sheet 11 is removed for washing or the like and the blowout port 38 is exposed,
There is an effect that foreign matter is unlikely to fall from above and enter the inside of the duct 9.

As a result, the troublesome and frequent setting for each use can be omitted, and the user can sleep comfortably without feeling much foreign matter at the outlet.

Further, there are the following effects peculiar to the above embodiments. (1) By making the outlet of the duct 9 oblique and projecting the upper part in the shape of an eaves, even if a flange is provided all around and prevention of pulling out and strength UP are achieved, there is little feeling of foreign matter at bedtime.

(2) By making the duct cross-sectional shape flat and substantially elliptical, the thinness is emphasized in terms of design and the bedside is clean.
