As shown in FIGS. 1 to 3, the futon drying mat 5 is formed by sewing a plurality of substantially rectangular box-shaped air flow tubes 7 on the lower surface of the outer packet sheet 6 formed in a substantially rectangular bag shape. Composed. The outer packaging sheet 6 is made of a non-ventilated polyester fiber fabric, is a rectangular sheet of 2100 [mm] in length and 2050 [mm] in width, and is folded and sewn with a width of 300 [mm] at both ends in the longitudinal direction. 43. An upper central portion of the outer sheet 6 has a ventilation portion 9 made of polyester fiber fabric having a ventilation property of 700 [mm] length and 500 [mm] width. (Here, the longitudinal direction of the futon drying mat is defined as the longitudinal direction, and the lateral direction is defined as the lateral direction.)

As shown in FIGS. 5 to 6, the futon drying mat 5 is attached to the mattress as follows. After covering the bag-shaped portions 42 and 43 on the longitudinal end portions of the mattress U, the lateral left and right end portions of the outer envelope sheet 6 are folded below the mattress U, respectively, so that the outer envelope sheet 6 is opened at the peripheral edge of the opening. It forms in the bag shape which has 22 and the opening 8, and wraps the mattress U. That is, the opening 8 is a position below the futon U and surrounded by the opening peripheral end portion 22 and the bag-like portions 42 and 43. Further, the opening peripheral end 22 is the left and right ends before weaving the outer sheet 6 on the lower side of the futon U. The outer sheet 6 is provided with a hose connection opening 10 at a position that becomes an end of the outer sheet 6 when the mattress U is wrapped.

The tube 7 is made of a non-ventilated polyester fiber fabric, and constitutes a hollow air passage that is sewn in a substantially rectangular shape and a rectangular shape. One side on the short side and the two sides on the long side are constituted by two rows of translational air paths. In addition, a hot air supply port 11 is provided at the end of the tube 7 on the outer side. The hot air supply port 11 is configured to protrude from the hose connection opening 10 to the outside of the outer sheet 6 when the tube 7 is integrated with the outer sheet 6. In the vicinity of the hot air supply port 11 of the tube 7, two rows of translational air paths are formed in both the vertical direction and the horizontal direction, so that the air path resistance is reduced and the hot air flowing in from the hot air supply port 11 is formed. Becomes easier to flow, and the temperature rise effect of the mattress U is enhanced.

As shown in FIG. 4, a pair of planar fasteners 18 and 19 are sewn on the inner periphery of the end portion of the hot air supply port 11 of the tube 7, and by sticking them after inserting the hose 4, A gap generated between the hose 4 and the hot air supply port 11 can be closed to prevent the hot air from leaking. A sheet fastener 20 is sewn on the inner periphery of the end of the hose connection opening 10 of the outer sheet 6, and a sheet fastener 21 is sewn on the outer periphery of the hot air supply port 11 of the tube 7 facing this. Yes. The hot air supply port 11 is fixed to the outer sheet 6 by passing through the hose connection opening 10 and then bringing the planar fasteners 20 and 21 into close contact therewith. Thereby, warm air can be prevented from leaking between the hose connection opening 10 and the warm air supply port 11. Thus, by providing a planar fastener in each of the hose connection opening 10 and the hot air supply port 11, they can be integrated after being sewn independently. Thereby, the sewing process sewn after uniting the hose connection opening 10 and the warm air supply port 11 can be simplified.

  An upper portion of the tube 7 is provided with an interlayer sheet 27 that covers the inside of the square shape and divides the space in the outer sheet 6 into two layers, a lower space S1 and an upper space S2. An interlayer opening 28 having an opening width of 200 [mm] that communicates the lower space S1 and the upper space S2 is provided near the short side of the interlayer sheet 27 on the warm air supply port 11 side. An inner opening 29, an inner opening 30, an inner opening 31, an inner opening 32, an inner opening 33, and an inner opening 34 are provided at the boundary between the inner side of the tube 7 and the interlayer sheet 27. An outer opening 41 having an opening width of 150 mm is provided on the outer side opposite to the opening 30.

Each inner opening is provided in three air paths except for one side of the downstream air path of the hot air supply port 11, and when hot air is supplied to the hot air supply port 11, the tube 7 expands, and the hot air flows into each inner opening. It is sent toward the inside of the character. The tube 7 is configured such that an end space S3 is formed between the outer opening 41 and the outer sheet 6 in a swelled state. That is, the length of the long side of the square is shorter than the long side of the outer sheet 6. Further, the interlayer opening 28 and the outer opening 41 have fasteners so that the opening can be opened and closed.

  As shown in FIGS. 5 and 6, the warm air sent from each inner opening is convected in the lower space S1 to warm the mattress U, and then sent from the interlayer opening 28 to the upper space S2. It is sent from the outer opening 41 to the end space S3 of the mattress U. The warm air sent from the outer opening 41 to the end space S3 warms the end surface of the mattress U and is sent to the upper space S2. The warm air sent out to the upper space S2 is sent out from the vent 9 after the outer sheet 6 is inflated. As described above, the narrow lower space S1 close to the mattress U is formed by the interlayer sheet 27, so that the heat transfer effect of the warm air to the mattress U is enhanced. In addition, the heat transfer efficiency in the end space S3 of the mattress U, which is a portion that is far from the hot air supply port 11 and hardly rises in temperature, is increased. Moreover, the temperature in the lower space S1 can be kept higher than the temperature in the upper space S2 by keeping the heat loss escaping to the outside of the outer sheet 6 only from the upper space S2, and the warming effect of the mattress U can be increased. Can be increased.

On the upper surface of the outer sheet 6, which is the surface on which the tube 7 is not provided, a fixing portion (a first portion) for folding and fixing the outer sheet 6 with the opening peripheral edge 22 positioned on the upper side of the sheet 6. A surface fastener which becomes a fixing part) is sewn.
Surface fasteners 80a and 81a, surface fasteners 80b and 81b, surface fasteners 80c and 81c, surface fasteners 80d and 81d, surface fasteners 81a and 82a, surface fasteners 81b and 82b, surface fasteners 81c and 82c, surface By bringing the shaped fasteners 81 d and 82 d into close contact with each other, as shown in FIG. 7, the opening peripheral end 22 which is both ends in the lateral direction of the outer sheet 6 can be fixed to the upper side.

As shown in FIGS. 8 and 9, the comforter drying mat 5 is simply fixed between the comforter T without fixing the outer peripheral edge 22 of the outer cover sheet 6 to the upper side and wrapping the comforter U with the outer cover sheet 6. The futon can also be dried by the method of wearing. When the futon drying mat 5 is simply attached between the mattress U and the comforter T, the fasteners of the interlayer opening 28 and the outer opening 41 are closed to eliminate leakage of warm air to the outside of the tube 7, A space S <b> 1 between the interlayer sheets 27 is formed. When hot air is supplied from the futon dryer main body 1 to the hot air supply port 11, the pressure in the B-shaped air passage rises and the tube 7 expands, and the comforter T is lifted from the periphery of the end. Thereafter, when the interlayer sheet 27 expands and the pressure inside the space S1 rises, the center portion of the comforter T is also lifted to form the space S1. The mattress U is warmed by heat conduction in the air passage portion with which the tube 7 contacts, and in the space S1, it is warmed by heat transfer by convection of warm air sent from each inner opening. Moreover, since the warm air of space S1 passes the clearance under the wind path of the tube 7, and the inside of the mattress U, the mattress U is warmed by heat transfer. The comforter T is warmed by heat conduction caused by contact with the air passage portion of the tube 7 and the interlayer sheet 27.

As described above, the futon drying mat 5 is used by putting the mattress U between the mattress U and the comforter in a state in which the opening peripheral edge 22 of the outer packet sheet 6 is folded upward and fixed without wrapping the mattress U with the outer packet 6. The mattress U and the comforter T can be dried by a simple method. Thereby, the usage method of the futon drying mat 5 can be selected according to the item among the drying effect and the importance of usability.

Next, as shown in FIG. 10 to FIG. 15, a usage pattern and operation in the case of drying small items such as clothes using the futon drying mat 5 will be described.
FIG. 10 is a perspective view of the futon drying mat 5 placed on the floor with the tube 7 side up. FIG. 11 is a perspective view in the middle of folding the futon drying mat 5. FIG. 12 is a perspective view of the futon drying mat 5 folded. FIG. 13 is a perspective view of the futon drying mat 5 when drying small items. FIG. 14 is an explanatory view of a longitudinal section of the futon drying mat 5 when drying small items.

When drying small articles such as clothes using the futon drying mat 5, as shown in FIG. 10, the futon drying mat 5 is spread on the floor so that the tube 7 side is on the upper side. At this time, the opening peripheral edge 22 of the outer sheet 6 is folded and fixed in advance so as to be positioned on the surface opposite to the tube 7. Then, an accessory to be dried such as clothing A is spread on the tube 7 and the interlayer sheet 27. At this time, the two fabrics of the outer sheet 6 are interposed between the tube 7 and the floor surface. In addition, a portion where two cloths of the outer sheet 6 are interposed between the interlayer sheet 27 and the floor surface, and a part where two sheets of cloth where the outer sheet 6 and the cloth of the ventilation portion 9 overlap each other are interposed. It becomes a certain structure.

Next, as shown in FIGS. 11 and 12, the drying mat 5 is folded in the vicinity of the center in the longitudinal direction so that the tube 7 is on the inside.
An annular fixing portion 84 is provided at the center of the end of the outer sheet 6 on the side of the hose connection opening 10. A fixed string 85 is provided at the center of the end of the opposite side of the hose connection opening 10.
And the fixing string 85 provided in the center part of the edge part of the opposite side of the hose connection opening 10 is attached to the ring-shaped fixing part 84 provided in the edge part center of the hose connection opening 10 side of the outer sheet 6. Fix it. The fixed string 85 is provided with planar fasteners 86a and 86b. The fixed ring 85 is passed through the ring-shaped fixing part 84 and the surface fasteners 86a and 86b are brought into close contact with each other, whereby the ring-shaped fixing part 84 and the fixed string 85 are fixed. The

When warm air is supplied from the main body 1 to the futon drying mat 5 via the hose 4, the futon drying mat 5 expands as shown in FIG. The folded mattress drying mat 5 tends to expand as it swells, but the ring-shaped fixing portion 84 and the fixing strap 85 fix the short sides of the outer sheet 6 facing each other at the approximate center, so that the folded state is maintained. .
That is, each of the ring-shaped fixing portion 84 and the fixing string 85 is a fixing member, and is a second fixing portion that fixes the overlapping envelope sheet 6 so as not to spread in a state of being folded in a pair.

The hot air supplied from the hose 4 through the hot air supply port 11 into the tube 7 inflates the tube 7 and the outer sheet 6. At this time, as shown in FIG. 14, the tube 7 is folded in two, so that the floor surface side of the tube 7 mainly swells. Then, warm air is sent to the space formed by the interlayer sheet 27 folded from the inner opening 32, the inner opening 33, and the inner opening 34, and the entire outer sheet 6 is expanded. The warm air passes through the folded tube 7 to the outside of the outer sheet 6. By comprising in this way, warm air passes between small articles, such as clothing A, in the outer package sheet 6, and is dried. Here, it is desirable to use the fasteners of the interlayer opening 28 and the outer opening 41 in a closed state, but since there is almost no flow of warm air to these openings, the same effect can be obtained without closing the fastener.

The hot air stays in the outer packaging sheet 6 after being supplied to the tube 7 until it leaves the outside. During this time, the heat of the hot air is exchanged with the floor and the outside air, so that heat such as clothing A is dried. Escape to the outside.
In the present embodiment, two sheets of outer sheet 6 are interposed between the tube 7 and the floor surface, and two sheets of outer sheet 6 or the outer sheet are interposed between the interlayer sheet 27 and the floor surface. By adopting a configuration in which two fabrics, each of the fabrics 6 and 1 of the ventilation portion 9 overlap, the tube 7 becomes a heat insulating structure that is not in direct contact with the outside air or the floor surface, and reduces heat escaping to the outside. Therefore, drying performance can be improved.

In addition, when clothing A is placed on tube 7 and dried, clothing A floats from the floor surface, so the drying performance is enhanced by the warming effect of heat conduction from the bottom of clothing A. it can.

  Since the outer packaging sheet 6 is fixed at the approximate center of the short sides facing each other at one portion where the annular fixing portion 84 and the fixing string 85 are fixed, the outer packaging sheet 6 is in a folded state. Will not spread out. In this way, by configuring the folding location to be one location, preparation and cleaning up when drying small items such as clothing are facilitated.
