PROBLEM TO BE SOLVED: To provide a futon (Japanese bedding) which can be easily dried. SOLUTION: A bag surface cloth 2 is formed with permeable cloth and filler cotton 3 is put thereinto. A flat bag part 4 is formed as a middle layer of poorly permeable cloth in the bag surface cloth 2 and the filler cotton 3 is put into upper and lower layers above and under the bag part 4. A warm air feed port 6 is equipped on the periphery part of the bag part 4 to feed warm air into the bag part 4. The upper and lower layers are superposed as futons 1a, 1b respectively filled with the filler cotton 3 and the superposed face sides of upper and lower futons 1a, 1b are constituted of poorly permeable cloth to make the bag part 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple drying type futon, and more particularly to a structure for easily drying a mattress.

[0002]

2. Description of the Related Art Conventionally, as a method of mechanically drying a futon, a mat-shaped air bag is interposed between a mattress and a comforter which are superimposed, and hot air is supplied to the air bag. It is known that the quilt is mainly dried by discharging the air from the airbag surface.

[0003] On the other hand, there is no special drying method for a mattress which is used throughout the year regardless of the season and is likely to contain moisture. In addition, there is a problem that effective drying is not performed as a result of insufficient supply of warm air to the inside of the futon besides discharging.

[0004] In addition, since the mattress is generally made of cotton having a short fiber length and inferior quality, even a new product having a high hygroscopicity can absorb a considerable amount of water in a few months (generally 120 g).
/ Day), the cushions are bad, the body temperature at bedtime is lost, and sleep is hindered. In addition, the weight of the futon is increased, and for elderly people, the burden of raising the floor is large. . The present invention is not particularly limited to the mattress, but in view of the characteristics of the mattress described above, an object of the present invention is to provide a structure mainly for facilitating drying of the mattress.

[0005]

A futon according to the present invention comprises a futon 1 in which a bag-like outer material 2 is formed from a highly air-permeable fabric, and a cotton pad 3 is inserted therein. A flat bag-shaped portion 4 is formed in the middle layer of the bag 2 with poor air permeability, and the cotton pad 3 is inserted into the upper and lower layers, which are spaces above and below the bag-shaped portion 4, to form a bag. In the peripheral part, a bag-shaped part 4
It is characterized in that a hot air supply port 6 for supplying hot air is provided therein.

[0006] Second, the upper layer and the lower layer are each filled with cotton 3.
The upper and lower futons 1a, 1b are overlapped with each other, and the overlapping surfaces of the upper and lower futons 1a, 1b are made of poorly air-permeable cloth and formed as a bag-like portion 4.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described below in detail. In the present invention, a bag-like outer material 2 is formed by a highly air-permeable cloth, and a cotton pad 3 is inserted therein. In the futon 1, a flat bag-shaped portion 4 is formed in the middle layer of the outer material 2 with a fabric having poor air permeability, and the cotton pad 3 is inserted into the upper layer and the lower layer which are spaces above and below the bag-shaped portion 4. A hot air supply port 6 with a zipper for supplying hot air into the bag-shaped portion 4 is provided at a peripheral portion of the bag-shaped portion 4.

In the present embodiment, the upper layer and the lower layer are overlapped as futons 1a and 1b, respectively, into which the inner cotton 3 is inserted, and the upper and lower futons 1a and 1b are formed of a cloth with poor air permeability. The peripheral edges are sewn together to form a bag-shaped portion 4.

The outer fabric 2 is a fabric generally used for mattresses, whereas the fabric of the bag-like portion 4 is deformed or deteriorated by hot air at 60 to 70 ° C., such as polyester cloth. A relatively heat-resistant fabric with high knitting density and poor air permeability is used. Other fabrics having similar properties may be used, and the fabric may be a heat-resistant resin-coated fabric or the like, and may be a sheet-like fabric having a large number of small holes for ventilation.

The use of the cloth having poor ventilation as described above is performed when hot air of a predetermined pressure is supplied from the hot air supply port 6.
By giving a constant ventilation resistance to the discharge of warm air from the peripheral wall of the bag-shaped part 4, the entire bag-shaped part 4 is inflated into an airbag (air mat) shape, and is substantially more than the entire peripheral surface of the bag-shaped part 4. This is to uniformly discharge warm air.

The cotton pad 3 may be a commonly used cotton,
Since the entire futon 1 is a single mattress, the upper and lower futons 1
According to the present invention, if the cotton amount of the conventional mattress is 6 to 7 kg, the cotton amount of each of the futons 1 a and 1 b is 2 to 2.5 kg, respectively.
Is enough.

A hot air supply port 6 is provided with a distal end of an exhaust hose (pipe) 7 of a hot air supply device (not shown) such as a home futon dryer or the like, for supplying hot air to the bag-shaped portion 4. The shape and structure are not limited to those shown in the figure, and the installation place may be provided at one place or at each side of the futon 1.

The warm air supplied into the bag-shaped portion 4 is
In addition to inflating itself into a flat airbag shape, it is released from the outer material 2 through the inner cotton 3 from the peripheral surface to dry the entire futon evenly. It also exterminates species. It is sufficient that the drying time is 30 to 40 minutes as a whole, and the upper and lower sides can be dried uniformly by inverting the work during the operation.

[0014]

The present invention is configured as described above.
By supplying warm air to the airbag-like space formed by the diffuser cloth formed in the middle layer of the futon, the entire upper and lower futons can be surely dried in a short period of time. No special drying airbag is required as before.

[0015] Further, by passing not only a simple drying but also a certain amount of warm air, it is possible to control germs and ticks in the inside, and there is an advantage that a clean and healthy futon suitable for always good sleep can be used.
