FIG. 5 is a vertical cross-sectional view when a drying operation state of the futon dryer according to the first embodiment of the present invention is viewed from the lateral direction. FIG. 6 is a vertical cross-sectional view when a drying operation state of the futon dryer according to the first embodiment of the present invention is viewed from the vertical direction.

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

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

Then, 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 air flow. As a result, hot air is generated. The warm air passes through the inside of the hose 2. The warm air reaches the warm air supply port 8. The hot air flows through the inside of 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 as to have an elliptical cross section. As a result, a square annular air passage is formed in the tube 6.

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

The warm air travels inside the tube 6 while exchanging heat with the surface of the end of the mattress U by heat conduction. The surface of the end of the mattress U is warmed by the heat exchange.

The warm air is delivered 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 lower space S1. As a result, the mattress U is warmed. The warm air is sent from the interlayer opening 28 to the upper space S2.

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

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

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

As shown in FIG. 7, in the outer covering sheet 7, both ends on the long side can be fixed to 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 used even in a state where both ends of the outer sheet 7 on the long side are fixed to the upper side. In this case, the futon drying mat 3 is easily attached between the mattress U and the comforter T in a state where the outer cover sheet 7 does not wrap the mattress U. As a result, the space S4 is formed between the mattress U and the interlayer sheet 27.

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

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

The warm air is delivered 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 S4, 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 the heat transfer of the hot air passing through the ventilation portion 18 of the outer cover sheet 7 and the warm air passing through the gap between the outer cover sheet 7 and the heat conduction from the contact portion with the outer cover sheet 7.

According to the first embodiment described above, the main part of the outer packet sheet 7 is formed of a non-breathable material. The outer cover sheet 7 covers from the upper side of the tube 6 to the end of the back side of the tube 6 and the mattress U. Therefore, the drying performance of the mattress U can be improved.

In addition, it is also possible to easily perform the preparatory work before the futon drying operation by folding the mattress U without wrapping it with the outer cover sheet 7 and changing it into a state of being folded and fixed above the end portion on the long side of the outer cover sheet 7. .. In this case, the mattress U and the comforter T can be dried with the comforter mat 3 easily attached between the mattress U and the comforter T. As a result, it is possible to select the method of using the futon dryer according to the important items of the drying effect and the usability.

Further, the outer packet sheet 7 includes a first bag-shaped portion 36 and a second bag-shaped portion 37. Therefore, the outer-packet sheet 7 can be easily attached to the mattress U.

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. Therefore, the warm air can be prevented from leaking from between the hose 2 and the hot air supply port 8 by simple sewing and assembly.

Further, the warm air supply port 8 projects outward from the hose connection opening 17. Therefore, the work of connecting 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. Therefore, hot air can be prevented from leaking from the hot air supply port 8 and the hose connection opening 17 by simple sewing and assembly.

In addition, the tube 6 partially has two rows of translation air passages. Therefore, in the tube 6, it is possible to widen the region where heat is conducted to the end portion of the mattress U. As a result, the effect of increasing the temperature of the mattress U can be enhanced. Further, the air passage resistance can be reduced. Therefore, the warm air can be made to flow easily. As a result, the effect of increasing the temperature of the mattress U can be further enhanced. Further, by lowering the height of the tube 6, the effect of lifting the comforter T can be enhanced.

The interlayer sheet 27 divides the inner space of the outer cover 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. Therefore, it is possible to enhance the heat transfer effect of the warm air to the mattress U. Further, the loss of heat escaping to the outside of the outer packet sheet 7 can be limited to only from the upper layer space S2. Therefore, 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.
