  In a state where the other side of the hose 2 is inserted into the hot air supply port 8, the first surface fastener 19 and the second surface are in close contact with each other outside the hot air supply port 8. As a result, the gap between the other side of the hose 2 and the hot air supply port 8 is closed.

  In a state where the hot air supply port 8 is inserted into the hose connection opening 17, the third planar fastener 21 and the fourth planar fastener 22 are in close contact with each other. As a result, the gap between the hot air supply port 8 and the hose connection opening 17 is closed. At this time, the hot air supply port 8 is fixed to the outer packaging sheet 7 in a state of protruding from the hose connection opening 17 to the outside of the outer packaging sheet 7.

Next, the procedure when the futon drying operation is performed will be described with reference to FIGS. 5 and 6.
FIG. 5 is a longitudinal sectional view when the drying operation state of the futon dryer according to Embodiment 1 of the present invention is viewed from the lateral direction. FIG. 6 is a longitudinal sectional view when the drying operation state of the futon dryer according to Embodiment 1 of the present invention is viewed from the longitudinal direction.

  First, the tube 6 and the outer sheet 7 are integrated. As a result, a futon drying mat 3 is formed. Thereafter, the futon drying mat 3 is placed on the surface of the mattress U. At this time, in the tube 6, the side far from the hot air supply port 8 is arranged closer to the center than the end of the mattress U.

  Thereafter, the end of the mattress U is lifted. Thereafter, the first bag-like portion 36 is put on one end portion on the short side of the mattress U. Thereafter, the second bag-shaped portion 37 is placed on the other end portion on the short side of the mattress U. Thereafter, each of the end portions on the long side of the outer sheet 7 is folded to the lower side of the mattress U having a length of about 300 [mm]. As a result, the outer sheet 7 becomes a bag and covers the tube 6 and the mattress from the front surface to the end of the back surface. Thereafter, the outer sheet 7 is covered with the comforter T. Thereafter, the other side of the hose 2 is inserted into the hot air supply port 8. Thereafter, the first planar fastener 19 and the second planar fastener 20 are brought into close contact with each other.

  Thereafter, the operation of the main body 1 is started. At this time, the blower fan 4 generates an air flow. The heater 5 heats the airflow. As a result, warm air is generated. The hot air passes through the inside of the hose 2. The hot air reaches the hot air supply port 8. The hot air flows through the tube 6 from the hot air supply port 8 in the vertical direction and the horizontal direction. At this time, the tube 6 swells so that the cross section becomes elliptical. As a result, a square annular air passage is formed in the tube 6.

  At this time, the internal space of the outer sheet 7 is divided into two layers, a lower layer space S1 and an upper layer space S2, by the interlayer sheet 27. Further, an end space S3 is formed between the end opening 31 and the outer sheet 7.

  The warm air advances through the inside of the tube 6 while performing heat exchange with the surface of the end portion of the mattress U by heat conduction. The surface of the end portion of the mattress U is warmed by the heat exchange.

  The warm air is sent out from the first inner opening 9, the second inner opening 10, the third inner opening 11, the fourth inner opening 12, the fifth inner opening 13, and the sixth inner opening 14. The hot air convects inside the lower layer space S1. As a result, the mattress U is warmed. The hot air is sent from the interlayer opening 28 to the upper layer space S2.

  The warm air is sent from the end opening 31 to the end space S3. The said warm air warms the surface of the edge part of the mattress U. The hot air is sent to the upper space S2.

  In the upper layer space S2, the warm air causes the outer sheet 7 to expand. The hot air is sent out from the ventilation part 18. The hot air passes through the gap between the outer sheet 7 and the comforter T and the interior of the comforter T and diffuses to the outside. At this time, the comforter T is warmed by heat transfer of the warm air passing through the gap between the warm air passing from the ventilation portion 18 of the outer sheet 7 and the outer sheet 7 and heat conduction from the contact portion with the outer sheet 7.

Next, the drying operation state by the simple mounting method will be described with reference to FIGS.
FIG. 7 is a perspective view showing a state in which the lateral end portion of the outer sheet of the futon dryer according to Embodiment 1 of the present invention is folded upward. FIG. 8 is a longitudinal cross-sectional view when the drying operation state by the simple mounting method of the futon dryer according to Embodiment 1 of the present invention is viewed from the lateral direction. FIG. 9 is a longitudinal sectional view when the drying operation state according to the simple mounting method of the futon dryer in Embodiment 1 of the present invention is viewed from the longitudinal direction.

  As shown in FIG. 7, in the outer sheet 7, both end portions on the long side can be fixed on the upper side. At this time, the pair of first fixing planar fasteners 42 are in close contact with each other. The pair of second fixing planar fasteners 43 are in close contact with each other. The pair of third fixing planar fasteners 44 are in close contact with each other. The pair of fourth fixing planar fasteners 45 are in close contact with each other. The pair of fifth fixing planar fasteners 46 are in close contact with each other. The pair of sixth fixing planar fasteners 47 are in close contact with each other. The pair of seventh fixing planar fasteners 48 are in close contact with each other. The pair of eighth fixing planar fasteners 49 are in close contact with each other.

  As shown in FIGS. 8 and 9, the futon drying mat 3 is also used in a state in which both end portions on the long side of the outer sheet 7 are fixed on the upper side. In this case, the futon drying mat 3 is simply mounted between the mattress U and the comforter T in a state where the outer sheet 7 does not wrap the mattress U. As a result, a space S4 is formed between the mattress U and the interlayer sheet 27.

  At this time, the fastener of the interlayer opening 28 and the fastener of the end opening 31 are closed. As a result, leakage of warm air to the outside of the tube 6 is prevented.

  When the warm air is supplied to the warm air supply port 8, the pressure inside the tube 6 increases. As a result, the tube 6 swells. At this time, the comforter T is lifted from the periphery of the end. Thereafter, when the pressure inside the space S4 rises, the center portion of the comforter T is also lifted. In the mattress U, the contact portion with the tube 6 is warmed by heat conduction.

  The warm air is sent out from the first inner opening 9, the second inner opening 10, the third inner opening 11, the fourth inner opening 12, the fifth inner opening 13, and the sixth inner opening 14. The warm air convects inside the space S4. As a result, the mattress U is warmed.

Inside the space S <b> 4, the warm air passes through the gap between the tube 6 and the mattress U and the interior of the mattress U. At this time, the mattress U is warmed by heat transfer.

  The comforter T is warmed by heat transfer of warm air passing through the gap between the warm air passing from the ventilation portion 18 of the outer sheet 7 and the outer sheet 7 and heat conduction from the contact portion with the outer sheet 7.

  According to Embodiment 1 demonstrated above, the principal part of the outer sheet | seat 7 is formed with non-breathable cloth. The outer sheet 7 covers the tube 6 from the upper side to the end of the back surface of the tube 6 and the mattress U. For this reason, the drying performance of the mattress U can be improved.

  In addition, by preliminarily changing the state in which the mattress U is folded and fixed to the upper side of the long side end of the outer sheet 7 without being wrapped with the outer sheet 7, the preparatory work before the futon drying operation can be easily performed. . In this case, the mattress U and the comforter T can be dried in a state where the comforter drying mat 3 is simply mounted between the mattress U and the comforter T. As a result, the use method of the futon dryer can be selected according to the important items among the drying effect and the usability.

  The outer sheet 7 includes a first bag-like portion 36 and a second bag-like portion 37. For this reason, mounting | wearing to the bedding U of the outer sheet | seat 7 can be performed easily.

  Further, the first planar fastener 19 and the second planar fastener 20 are in close contact with each other outside the warm air supply port 8. For this reason, it is possible to prevent the warm air from leaking between the hose 2 and the warm air supply port 8 by simple sewing and assembly.

  Further, the hot air supply port 8 protrudes outside the hose connection opening 17. For this reason, the connection work of the hose 2 can be easily performed.

  The third planar fastener 21 and the fourth planar fastener 22 are in close contact with each other. For this reason, it is possible to prevent the warm air from leaking from the warm air supply port 8 and the hose connection opening 17 by simple sewing and assembly.

  Moreover, the tube 6 has a translation air path of 2 rows partially. For this reason, in the tube 6, the area | region thermally conductive to the edge part of the mattress U can be enlarged. As a result, the temperature rise effect of the mattress U can be enhanced. Further, the air path resistance can be reduced. For this reason, warm air can be made to flow easily. As a result, the temperature rise effect of the mattress U can be further enhanced. Moreover, the effect which lifts the comforter T can be heightened by making the height of the tube 6 low.

  The interlayer sheet 27 divides the internal space of the outer sheet 7 into a lower layer space S1 and an upper layer space S2. The lower layer space S1 is a narrow space close to the mattress U. For this reason, the heat transfer effect to the mattress U of warm air can be heightened. Moreover, the heat loss which escapes to the exterior of the outer sheet | seat 7 can be stopped only from upper layer space S2. For this reason, the temperature inside the lower layer space S1 can be kept higher than the temperature inside the upper layer space S2. As a result, the warming effect of the mattress U can be enhanced.
