Description

  The present invention relates to a futon dryer.

  Patent document 1 discloses a futon dryer. In the futon dryer, the futon drying mat includes a mat and a sheet. The futon drying mat is attached between the mattress and the comforter. The main body generates warm air. The hot air reaches the hot air supply port of the mat via the hose. The hot air inflates the mat. The hot air is sent from the hot air outlet of the mat to the interior space of the sheet. As a result, the mattress and comforter are dried.

Japanese Patent No. 2909971

  However, in the futon dryer described in Patent Document 1, the sheet is entirely breathable. For this reason, heat escapes from the portion of the seat where the comforter is not in contact.

  Further, the hose is connected to the hot air supply port of the mat while being passed through the through hole of the sheet. For this reason, not only can the hose not be easily connected to the hot air supply port, but also the hot air leaks outside through the gap between the hot air supply port and the through hole.

Embodiment 1 FIG.
FIG. 1 is a perspective view of a futon dryer according to Embodiment 1 of the present invention excluding a comforter during a futon drying operation. FIG. 2 is an exploded perspective view of the futon dryer according to Embodiment 1 of the present invention excluding the comforter during the futon drying operation.

  As shown in FIGS. 1 and 2, the mattress U is formed in a rectangular shape. The longitudinal direction of the mattress U is defined as the longitudinal direction. The short direction of the mattress U is defined as the lateral direction.

  The futon dryer includes a main body 1, a hose 2, and a futon drying mat 3.

  The main body 1 includes a blower fan 4 and a heater 5. The hose 2 is formed in a hollow shape. One side of the hose 2 is connected to the main body 1. The futon drying mat 3 includes a tube 6 and an outer sheet 7.

  For example, the tube 6 is formed in substantially the same size as the mattress U. For example, the tube 6 is formed slightly smaller than the mattress U. The tube 6 is formed in a square ring shape from a non-breathable fabric. For example, the tube 6 is sewn in an annular shape with a polyester fiber fabric.

  For example, the tube 6 includes a hot air supply port 8, a first inner opening 9, a second inner opening 10, a third inner opening 11, a fourth inner opening 12, a fifth inner opening 13, and a sixth inner opening 14. .

  For example, the hot air supply port 8 is formed at one end of the short side of the tube 6. 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 are the length of the tube 6 on the side of the hot air supply port 8. It is provided on one of the three sides excluding the side.

  For example, the width dimension of the first inner opening 9 is 150 [mm]. For example, the width dimension of the second inner opening 10 is 150 [mm]. For example, the width dimension of the third inner opening 11 is 100 [mm]. For example, the width dimension of the fourth inner opening 12 is 100 [mm]. For example, the width dimension of the fifth inner opening 13 is 100 [mm]. For example, the width dimension of the sixth inner opening 14 is 70 [mm].

  The outer sheet 7 is formed in a rectangular shape. The main part of the outer package sheet 7 is formed of a non-breathable fabric. For example, the main part of the outer sheet 7 is formed of a polyester fiber fabric.

  The outer sheet 7 includes a bag-like portion 15, a lower opening 16, a hose connection opening 17, and a ventilation portion 18.

  The bag-like portion 15 is formed on the outer peripheral portion of the outer sheet 7. The lower opening 16 is formed in the lower central portion of the outer sheet 7. The lower opening 16 is formed with a size smaller than the outer shape of the outer sheet 7. The hose connection opening 17 is formed at one end of the short side of the outer sheet 7. The ventilation part 18 is formed in the central part above the outer sheet 7. The ventilation part 18 is formed of a breathable fabric. For example, the ventilation part 18 is formed with a polyester fiber fabric. For example, the vertical dimension of the ventilation part 18 is 700 [mm]. For example, the lateral dimension of the ventilation part 18 is 500 [mm].

Next, the connection between the other side of the hose 2 and the futon drying mat 3 will be described with reference to FIG.
FIG. 3 is a longitudinal sectional view of the main part of the futon dryer according to the first embodiment of the present invention as viewed from the side.

  As shown in FIG. 3, the first planar fastener 19 is provided on one side of the inner peripheral surface of the end of the hot air supply port 8. For example, the first planar fastener 19 is sewn on the upper side of the inner peripheral surface of the end portion of the warm air supply port 8. The second planar fastener 20 is provided on the other side of the inner peripheral surface of the end of the warm air supply port 8. For example, the second planar fastener 20 is sewn on the lower side of the inner peripheral surface of the end portion of the warm air supply port 8.

  For example, the third planar fastener 21 is sewn to the outer peripheral surface of the hot air supply port 8. For example, the fourth planar fastener 22 is sewn to the inner peripheral surface of the end portion of the hose connection opening 17.

  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. 4 and 5.
FIG. 4 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. 5 is a longitudinal sectional view when the drying operation state of the futon dryer according to the first embodiment 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. Thereafter, the end of the mattress U is lifted. Thereafter, the end of the mattress U is inserted from the lower opening 16 to the end of the outer sheet 7. As a result, the outer sheet 7 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 warm air advances through the inside of the tube 6 while exchanging heat 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 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 to the center side of the surface of the mattress U. Is done. The warm air inflates the outer sheet 7 while heating the surface of the mattress U inside the tube 6. As a result, a space S is formed between the mattress U and the comforter T.

  Inside the space S, the warm air warms the entire surface of the mattress U. The hot air passes through the mattress U and diffuses from the lower opening 16 of the outer sheet 7 to the outside. At this time, the mattress U is warmed by warm air.

  Inside the space S, the warm air is sent out from the ventilation portion 18 of the outer sheet 7. 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 the heat transfer of the warm air passing through the gap between the warm air passing through the ventilation portion 18 of the outer sheet 7 and the outer sheet 7 and the heat conduction from the portion in close contact 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. The inner peripheral surface of the hose connection opening 17 is in close contact with the outer peripheral surface of the hot air supply port 8. For this reason, not only can the preparatory work before the futon drying operation be performed easily, but also the futon drying performance can be enhanced.

  Specifically, the outer sheet 7 does not leak warm air from the end of the mattress U. Furthermore, the envelope sheet 7 does not leak hot air from the hose connection opening 17. For this reason, the drying performance of the mattress U can be improved. As a result, the mattress U can be efficiently and uniformly dried by efficiently and uniformly heating the entire mat including the end portion of the mattress U.

  Further, the warm air is sent out from the ventilation portion 18 after warming the mattress U. For this reason, the comforter T can also be efficiently warmed and dried.

  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 increase the speed of the warm air. For this reason, the heat transfer efficiency to the inside of the center side of the mattress U can be increased.

  The widths of the first inner opening 9 and the second inner opening 10 are wider than the widths of the third inner opening 11, the fourth inner opening 12, the fifth inner opening 13, and the sixth inner opening 14. As a result, the areas of the first inner opening 9 and the second inner opening 10 are larger than the areas of the third inner opening 11, the fourth inner opening 12, the fifth inner opening 13, and the sixth inner opening 14. Therefore, the flow of warm air in the longitudinal direction of the mattress U becomes stronger. For this reason, the heat transfer efficiency to the surface of the mattress U can be increased.

  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.

  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.

  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.

  In addition, on the side of the end portion of the mattress U, the release of heat to the outside air is large. For this reason, the temperature at the end of the mattress U tends to be low. On the other hand, in the futon drying mat 3, the tube 6 spreads the heat of high-temperature hot air to the end side of the duvet U first. For this reason, it can suppress that the temperature of the edge part side of the mattress U becomes low.

  At this time, the temperature of the warm air decreases as it moves away from the warm air supply port 8. For this reason, on the side away from the hot air supply port 8, the temperature rise effect due to heat conduction from the tube 6 is reduced. In contrast, the width of the first inner opening 9 and the second inner opening 10 is large. For this reason, the temperature on the side away from the hot air supply port 8 can be increased.

  The sixth inner opening 14 is closest to the hot air supply port 8. For this reason, warm air is easy to send out. On the other hand, the width of the sixth inner opening 14 is narrower than the widths of the other inner openings. For this reason, the air volume sent from the sixth inner opening 14 can be suppressed. As a result, it is possible to suppress a decrease in the air volume from the other inner opening.

Moreover, in the case of the futon dryer used in the range of the amount of warm air of 0.5-1.0 [m < ³ > / min], the wind speed of the warm air sent from each inner opening is 20-50 [m / min]. The opening width of each inner opening may be set to be within the range of [sec]. In this case, the heat transfer efficiency to the mattress U can be increased.

  Further, no opening is provided on the inner side between the hot air supply port 8 and the first inner opening 9. For this reason, strong warm air can be prevented from flowing in the lateral direction of the mattress U. As a result, it is possible to prevent the hot air flow in the vertical direction from being hindered.

  Note that the amount of hot air diffused from the lower opening 16 is affected by the density inside the mattress U, the size of the gap between the mattress U and the floor, and the ventilation resistance (ventilation rate and area) of the ventilation portion 18. For this reason, by passing a mat that secures a gap under the mattress U, or adjusting the balance between the ventilation resistance of the ventilation portion 18 and the passage amount on the mattress U side, the passage of warm air to the mattress U The amount can be increased.

  Moreover, the part which cannot be covered with the comforter T in the outer sheet | seat 7 is exposed outside. For this reason, heat loss occurs due to heat transfer between the outer sheet 7 and the outside air. On the other hand, the part exposed to the outside in the outer sheet 7 is formed of a non-ventilated fabric. For this reason, it is possible to prevent the warm air from directly going outside. As a result, heat loss can be suppressed. Moreover, in the outer sheet | seat 7, you may cover the part exposed by adding a futon or a mat | matte. Also in this case, heat loss can be suppressed.

Embodiment 2. FIG.
FIG. 6 is a perspective view of the futon dryer according to Embodiment 2 of the present invention excluding the comforter during the futon drying operation. FIG. 7 is an exploded perspective view excluding a comforter during a futon drying operation of the futon dryer according to Embodiment 2 of the present invention. FIG. 8 is a longitudinal sectional view when the drying operation state of the futon dryer according to the second embodiment of the present invention is viewed from the lateral direction. FIG. 9 is a longitudinal sectional view when the drying operation state of the futon dryer according to the second embodiment of the present invention is viewed from the longitudinal direction. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1, or an equivalent part. The description of this part is omitted.

  In the tube 6 of the second embodiment, the short side and both long sides on the warm air supply port 8 side form two rows of translation air paths. In the second embodiment, the tube 6 includes a first outer opening 23, a second outer opening 24, a third outer opening 25, and a fourth outer opening 26. The first outer opening 23, the second outer opening 24, the third outer opening 25, and the fourth outer opening 26 are formed outside the four corners of the tube 6. For example, the width of the first outer opening 23, the width of the second outer opening 24, the width of the third outer opening 25, and the width of the fourth outer opening 26 are 50 [mm].

  According to Embodiment 2 demonstrated above, 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 first outer opening 23, the second outer opening 24, the third outer opening 25, and the fourth outer opening 26 are formed outside the four corners of the tube 6. At this time, the warm air is also sent to the four corners of the mattress U. For this reason, the four corners of the mattress U can be efficiently heated. As a result, the temperature rise effect of the mattress U can be enhanced as a whole.

  Moreover, the short side on the side away from the hot air supply port 8 forms a row of air paths. Even in this case, the heat transfer effect by the warm air sent out from the first inner opening 9 and the second inner opening 10 having a wide opening width is large, and therefore the temperature increase effect is not lower than the other portions.

  Note that two rows of translational air paths may be formed on the short side away from the hot air supply port 8. There is no significant difference in the temperature rise effect of the mattress U.

Embodiment 3 FIG.
FIG. 10 is a perspective view of the futon dryer according to Embodiment 3 of the present invention excluding the comforter during the futon drying operation. FIG. 11 is an exploded perspective view of the futon dryer according to Embodiment 3 of the present invention excluding the comforter during the futon drying operation. FIG. 12 is a longitudinal sectional view when the drying operation state of the futon dryer according to the third embodiment of the present invention is viewed from the lateral direction. FIG. 13: is a longitudinal cross-sectional view when the drying operation state of the futon dryer in Embodiment 3 of this invention is seen from the vertical direction. FIG. 14 is a plan view showing a sewing configuration of a tube according to Embodiment 3 of the present invention. In addition, the same code | symbol is attached | subjected to the part which is the same as that of Embodiment 1 or Embodiment 2, or an equivalent part. The description of this part is omitted.

  In Embodiment 3, the futon dryer includes an interlayer sheet 27. For example, the interlayer sheet 27 is formed of a non-breathable polyester fiber fabric. The interlayer sheet 27 closes the space inside the tube 6 from above. As a result, the internal space of the outer sheet 7 is divided into two layers, a lower layer space S1 and an upper layer space S2.

  The interlayer sheet 27 includes an interlayer opening 28. The interlayer opening 28 is formed near the short side of the interlayer sheet 27 on the warm air supply port 8 side on the side opposite to the warm air supply port 8 side. For example, the width of the interlayer opening 28 is 150 [mm].

  In the tube 6, 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 are at the boundary with the interlayer sheet 27. It is formed.

  As shown in FIG. 14, the tube 6 is formed by sewing a rectangular sheet 29 and an annular sheet 30, which are a combination of an upper surface of a rectangular annular air passage and an interlayer sheet 27, at a broken line portion in the drawing. Is done. 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 are composed of a rectangular sheet 29 and a square annular sheet 30. It is formed by the parts that are not worn. As a result, the sewing process when forming 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 is simplified. .

  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 hot air inflates the outer sheet 7. The hot air is sent out from the ventilation part 18.

  According to the third embodiment described above, 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.

The description of this part is omitted.

  The width of the interlayer opening 28 in the fourth embodiment is different from the width of the interlayer opening 28 in the third embodiment. For example, the width of the interlayer opening 28 is 200 [mm]. The interlayer opening 28 is provided so as to be freely opened and closed by a fastener (not shown).

  The long side of the tube 6 is shorter than the long side of the outer sheet 7. The tube 6 includes an end opening 31. The end opening 31 is formed outside the short side opposite to the hot air supply port 8 of the tube 6. For example, the width of the end opening 31 is 150 [mm]. The end opening 31 is provided to be freely opened and closed by a fastener (not shown).

  As shown in FIG. 16, the tube 6 includes a first detachable planar fastener 32, a second detachable planar fastener 33, a third detachable planar fastener 34, and a fourth detachable planar fastener 35. The first attachment / detachment planar fastener 32, the second attachment / detachment planar fastener 33, the third attachment / detachment planar fastener 34, and the fourth attachment / detachment planar fastener 35 are formed above the four corners of the tube 6.

  As shown in FIGS. 19 and 20, when the tube 6 is used alone, 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. For this reason, a space S <b> 4 is formed between the mattress U and the interlayer sheet 27.

  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. For this reason, the comforter T is lifted from the periphery of the end. Thereafter, the interlayer sheet 27 expands. As a result, the pressure inside the space S4 increases. For this reason, the center part of the comforter T is also lifted.

  In the mattress U, the portion in contact with the tube 6 is warmed by heat conduction. In the space S4, the surface of the mattress U 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. It is warmed by heat transfer by convection of warm air.

  The warm air in the space S4 passes through the gap below the air passage of the tube 6 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 conduction caused by contact with the air passage of the tube 6 and contact with the interlayer sheet 27.

  According to Embodiment 4 demonstrated above, the tube 6 is provided with respect to the outer sheet | seat 7 so that attachment or detachment is possible. In this case, the mattress U and the comforter T can be dried by a simple method in which the tube 6 is used alone. For this reason, the usage method of a futon dryer can be selected according to the item important among a drying effect and usability.

  Further, 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. For this reason, it is possible to increase the heat transfer efficiency in the space S4 where the end portion of the mattress U, which is a portion far from the hot air supply port 8 and does not easily rise in temperature, exists.
