Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blower bedding which can dry bedding on a bed.

[0002]

2. Description of the Related Art Conventionally, as this kind of blown bed, FIG.
And had a structure as shown in FIG. That is, the user himself sandwiches the cloth-made blower mat 3 between the box sheets 1 and the comforter 2 covered by the bed mattress, and connects the blower holes 4 and the ventilation passages 5 provided at the end of the blower mat 3 to each other. Further, the hot air generator 6 having an electric heater is communicated with each other through the air passage 5. Then, by sending warm air to the blower mat 3 and blowing out warm air into the bed through the cloth, the box sheets 1 and the bed pad or bed mattress thereunder, or the comforter 2 is dried.

[0003]

However, in the conventional structure as described above, the blower mat 3 is inserted into the center of the bedding to extend the wrinkles and the ventilation passage 5 and the warm air generator 6 are set. It was necessary to carry out a complicated operation.

Further, in order to solve the above problems, when the air-blowing mat is fixed to the bed and the person sleeps on the bed, the ventilation of the cloth of the air-blowing mat due to the load of the human body or the washing lowers the air permeability of the cloth over time. In addition, there is a problem that the cloth is clogged due to dust or the like and the drying performance deteriorates.

Therefore, a first object of the present invention is to provide an easy-to-use blower bedding that does not require the trouble of laying the blower mat each time it is used.

A second object is to uniformly dry the entire bedding up to the end of the bedding, and to realize stable ventilation over time even when used daily.

[0007]

In order to achieve the above first object, the present invention sewes a bed mattress in a box shape so as to enclose it, and has a warm air inlet at approximately the center of the long side of the upper surface thereof. And a warm air unit attached to the side of the bed and having a heater and a blower and a warm air outlet,
The hot air inlet and the hot air outlet communicate with each other, and a blower duct is provided.

Further, in order to achieve the above second object, the blower sheet of the present invention has a total number of finished punchings of 240 / inch or more in total, and has at least 3 cotton fibers.
A plain weave high-density woven fabric containing 0% or more was sewn in a box shape so as to wrap around the bed mattress with the vertical and horizontal dimensions being slightly larger than the bed mattress, and the warm air that flowed into the upper surface of the bed mattress was above the grain of the high-density fabric. It is configured to pass through to.

[0009]

With the above-described structure, the blower bed of the present invention blows warm air from the warm air unit between the mattress and the blower sheets via the blower duct, and blows the blown sheets evenly from the woven cloth to the upper surface.

Further, the blower sheet according to the present invention has the above-mentioned structure, so that the cloth is less likely to sag due to the load of the human body, and the air permeability is recovered by the cloth contraction during washing.

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 thin hot air unit having a heater and a blower built therein, which is attached to the center of the side frame of the bed 9. The hot air is sent from the hot air unit 7 to the hot air inlet 10 via the air duct 8 so that the hot air flows between the air blowing sheets 11 and the bed mattress.

FIG. 2 is an external perspective view of the embodiment. The blower sheet 11 is sewn in a box shape so as to wrap around the bed mattress 12 and the bed pad 13, and a warm air inlet 10 is provided at the center of the long side of the upper surface thereof, and the blower duct 8 is connected to the warm air inlet 10. It communicates with the unit 7. Further, a rubber cord 14 is sewn on the lower end of the blower sheet 11 over the entire circumference, so that it is firmly attached to the bed mattress 12. Further, the blower duct 8 is an elastomer molded product having a rectangular cross section, and has a retaining flange at the tip thereof, and is connected to the warm air outlet 15 of the warm air unit through a bent portion and a bellows portion of about 90 °. There is. In addition, 16 is a side frame of the bed 9,
Reference numeral 17 is a floor board, and 18 is a headboard.

FIG. 3 is an external perspective view of the hot air inlet in the embodiment. FIG. 4 is a partial sectional view of the same. The planar fastener projections 19 and the planar fastener recesses 20 are sewn on the cutout portions of the blower sheets 11 as shown in the figure, and the distal end portions of the blower ducts 8 are inserted into the holes to insert the planar fasteners 1.
It can be joined by picking both ends of 9, 20.

The blower sheets 11 are made of 65% cotton in both history and history.
Finished with 35% polyester, # 40 single yarn, 143 warp threads, 112 weft threads (255 total threads)
The plain weave high density woven fabric of was used. In addition, the sewing size was made larger by 5% in both length and width than the bed mattress size. FIG. 5 shows the relationship between the total number of shots and the fabric air permeability. The air permeability is JIS L 109.
6 It measured based on the Frazier type method. When the number of implants exceeds 230 lines / inch, the air permeability decreases drastically, and above 240 lines / inch, the air permeability is 1 cc / cm ² · s.
It does not change much below ec. 100% cotton here
The data for # 40 single yarn is shown.
Although the yarns of Nos. 30 to # 50 have some variations, they have a stable low air permeability when the number of threads is 240 or more per inch.

As a method of controlling the air permeability of the woven fabric, there is a process of flatly pressing the fabric with a high pressure calender or the like to crush the fabric. Therefore, when the air permeability is set, there is a problem that the air permeability is easily increased due to repeated body load, rolling over, and washing. On the other hand, the plain woven fabric having a high density of the number of finished shots has the effect that the deviation of the weave is small and the change in air permeability is extremely small with respect to the deterioration mode.

With this structure, the warm air discharged from the warm air unit 7 passes through the blower duct 8 and the blower sheet 1
It is blown out inside 1. As the pressure in the blower sheet 11 increases, the blower sheet 11 swells and a hot air passage can be secured to both ends of the foot and chest, and the warm air is blown out uniformly from the upper surface. The static static pressure when a standard comforter was hung was about 15 mmAq, and uniform comforter drying could be achieved with a thin compact type fan that can be attached to the side surface of the side frame 16. this is,
Since the warm air inlet 10 is provided at the center of the long side, the distance from the warm air inlet 10 to the end of the bed mattress 12 is small and the blowing efficiency is very good.
Further, since the warm air inlet 10 is located at the center of the long side, the warm air inlet 10 can be attached from either the left or right side surface, and the usability is improved.

Further, it is possible to use the sheet as a conventional box type sheet without the need for laying it in each time when drying with warm air. Then, the cotton fibers contained therein shrink every time the laundry is washed, so that a change in air permeability over time can be prevented and stable air blowing can be realized. This effect becomes remarkable when the cotton fiber content is 30% or more. Also, cotton fibers are comfortable to use as bedding.

The sewn size of the blower sheet 11 is increased by 5% in both length and width as compared with the size of the bed mattress 12. This is due to shrinkage during washing, leakage of warm air from the side surface of the bed mattress, and the blown sheet during operation. This is in consideration of the swelling condition of 11.

[0020]

According to the present invention, a bed mattress is sewn in a box shape so as to wrap it, and a blower sheet having a warm air inlet at approximately the center of the long side of the upper surface thereof, a heater attached to the side surface of the bed, and a blower. The following effects are obtained by providing a warm air unit having a built-in hot air outlet and a blower duct that connects the warm air inlet and the warm air outlet. 1. It can be used as conventional box-type sheets without the need to lay it down one by one when using it. 2. It can be installed from either the left or right side, improving usability, and because warm air is blown from approximately the center of the long side of the upper surface, warm air can easily spread, and even the warm air unit on the side of the bedding can sufficiently dry the bedding.

According to the present invention, a plain weave high-density woven fabric having a total number of finished shots of 240 / inch or more and containing at least 30% of cotton fibers has a lengthwise and transverse dimension slightly larger than that of the bed mattress and wraps the bed mattress. The following effects are obtained by sewn in a box shape and providing warm air that has flowed into the upper surface of the bed mattress above the grain of the high-density fabric. 1. Stable control with low air permeability allows warm air to reach the edges of the bedding and evenly dry the bedding. 2. As the cotton fiber shrinks during washing, it is possible to prevent an increase in air permeability over time and realize stable air blowing.
