[0007] Hereinafter, the details of the embodiments of the present invention will be described with reference to the drawings. In this specification and the drawings, components having substantially the same functional configurations are denoted by the same reference numerals, and duplicated explanations will be omitted.
[0008] (Overall composition) First, the overall configuration of the dryer according to this embodiment will be described. Figures 1 to 3 are a perspective view, a front view, and a plan view, respectively, showing the configuration of the dryer according to this embodiment. Hereinafter, the front side of the dryer 1 will be referred to as the front, the back side as the back, and the direction perpendicular to the front-rear direction and the up-down direction will be referred to as the left-right direction.
[0009] 1 to 3, the dryer 1 according to this embodiment includes a main body 2 and a movable placement section 3 that is housed within the main body 2 and is adapted to place a futon to be dried by the dryer 1. The placement section 3 is movable in the front-rear direction (the direction of the arrow in FIG. 1) within the drying space D of the main body 2. In other words, when a futon is to be hung on the placement section 3, it is pulled outward from the drying space D of the main body 2 and returned to its original position after it has been placed.
[0010] The main body 2 includes a housing 20, a gas heater 21, an exhaust fan 22, and a control unit 24. The housing 20 is formed as a hollow, substantially rectangular box shape overall, and defines a drying space D therein, surrounded by an upper wall 25 (see FIG. 9, etc.), a pair of side walls 26, a rear wall 27, a bottom wall 28, and a door 29. A movable mounting unit 3 can be housed in this drying space D.
[0011] The door section 29 is attached to one of the side walls 26 by a hinge or the like so as to be openable and closable, and allows the placement section 3 to be taken in and out of the drying space D from the front side. A part of the door section 29 is formed as a light-transmitting window section 291 made of, for example, glass, and is further provided with a grip section 292 for allowing a user to open and close the door section 29.
[0012] The gas heater 21 is provided above the upper wall 25 and at the rear end of the housing 20, and has a gas burner to heat air and supply the heated air (hot air) to an intake passage 251 (see FIG. 12) described later through a connecting pipe 253 (see FIG. 3). The gas heater 21 may be replaced by another device that heats air by another method.
[0013] The exhaust fan 22 is provided in front of the gas heater 21, and has a check damper 221 for preventing backflow of air, sucks in air within the drying space D, and exhausts it to the outside via the check damper 221.
[0014] The control unit 24 is provided in front of the exhaust fan 22, i.e., at the frontmost part of the housing 20, and has an operation panel 241 that allows a user to give instructions regarding the operation of the dryer 1, and is provided so that the operation panel 241 faces forward. Based on operations performed on the operation panel 241, the control unit 24 controls the operations of the gas heater 21, the exhaust fan 22, and a jet nozzle 23 (see FIG. 9) described later.
[0015] The movable placement section 3 is configured to be movable in the front-rear direction. When using the placement section 3, the user opens the door section 29 and moves the placement section 3 housed in the drying space D forward to some extent, pulling the placement section 3 out of the drying space D in the direction of the outer arrow in Fig. 1, and places a futon on it. After placing the futon, the user moves the placement section 3 backwards (the storage direction) and stores it again in the drying space D, and closes the door section 29. The user can then operate the operation panel 241 to cause the dryer 1 to perform the desired drying operation, thereby drying the futon.
[0016] The bottom wall 28 of the housing 20 functions as a part of a travel path when the mounting unit 3 is moved back and forth, and also functions as an exhaust flow path when the mounting unit 3 is accommodated in the drying space D. The bottom wall 28 will be described in detail later together with the following explanation of the configuration of the mounting unit 3.
[0017] (Placement section 3) The configuration of the movable placement unit 3 will be described in detail. Figs. 4 to 6 are a perspective view, a front view, and a side view, respectively, showing the configuration of the placement unit 3. Figs. 7 and 8 are a front view and a side view, respectively, showing the placement unit on which the futon F is placed. Fig. 9 is an overall side view of the dryer according to the embodiment. Fig. 10 is a view showing the flow direction of hot air flowing from the gas heater to the upper wall of the dryer according to the embodiment. Fig. 11 is a view showing the flow direction of hot air flowing from the upper wall of the dryer according to the embodiment to the drying space of the main body. Fig. 12 is a side view showing the overall flow of hot air in the dryer according to the embodiment. As shown in Figs. 4 to 6, the placement unit 3 includes a placement table 31, a base portion 32, and a pressing band 33.
[0018] The mounting table 31 is formed as a whole in a hollow, generally triangular prism shape (for example, a vaulting box shape) with the top and bottom surfaces facing the front-rear direction and one side surface facing downward, which faces the apex formed at the most acute angle. In the following description, the front side of the top and bottom surfaces of the triangular prism is the front surface of the mounting table 31, the other side is the back surface of the mounting table 31, and the one side surface of the triangular prism facing downward is the bottom surface of the mounting table 31. The other two inclined side surfaces and the curved surface formed at the upper end are the mounting surface of the mounting table 31. Therefore, the mounting surface has a shape in which a plane is bent so that a virtual folding line facing the front-rear direction is positioned at the upper end. The bottom surface of the mounting table 31 is connected to the upper surface of the pedestal portion 32.
[0019] As shown in FIG. 6, the mounting table 31 has a width of 100 cm and a height of 100 cm. m The mounting table 31 has an internal space P( figure5 or 12, etc.) and the drying space D. Air flows between the drying space D and the internal space P through this punched hole group 311. These punched hole groups 311 are provided over a predetermined distance from the uppermost end of the mounting table 31, and this predetermined distance is preferably equal to or greater than half the longitudinal width of the futon. Here, the mounting table 31 is formed by joining three metal plates such as stainless steel. The joints of the metal plates (the joints between the upper and lower plates shown in FIG. 6) are bent inward (toward the internal space P) to increase strength.
[0020] The placement table 31 has areas 311a, 311b, and 311c on the front, back, left and right sides and bottom side where the punched hole group 311 is not formed. The back side in FIG. 6 has the same shape. The width of the areas 311a and 311b is, for example, 60 mm to 150 mm (for example, about 140 mm). The width of the area 311c is 100 mm to 250 mm (for example, about 200 mm). The areas 311a, 311b, and 311c are where the ends of the futon placed on the placement table 31 are located. A certain degree of adhesion is required at the peripheral end of the futon so that the hot air does not leak. By providing the areas 311a, 311b, and 311c, there is no need to worry about the hot air leaking. On the other hand, the hot air flows through the small gaps that are generated between the end of the futon and the contact surfaces of the areas 311a, 311b, and 311c, so that the end of the futon is also dried.
[0021] Each hole in the punched hole group 311 has a curved surface formed on the drying space D side, i.e., the peripheral portion on the side where the futon F comes into contact (upper side in the figure), so that the diameter increases toward the drying space D side. Therefore, each hole in the punched hole group 311 has an opening diameter (hole diameter) on the drying space D side that is larger than the opening diameter on the internal space P side. Instead of a curved surface, a tapered surface may be formed so that the diameter increases toward the drying space D side.
[0022] Further, on the front surface of the placement table 31, a grip portion 312 is provided which is gripped by the user when moving the placement table 3.
[0023] When placing the futon F to be dried on the placement table 31, as shown in Fig. 7, the short side direction of the futon F is oriented in the front-to-rear direction of the placement table 31, and the futon F is placed on the placement surface of the placement table 31 so as to cover the punched hole group 311. At this time, the futon F is folded so as to follow the slope of the placement surface.
[0024] The upper end of the mounting table 31 is formed into a curved surface having a curvature, and the radius of curvature is preferably at least 0.9 times the thickness of the futon F to be placed on it. By forming a curved surface having such a radius of curvature, when the futon F is folded and placed on it, the folded part of the futon F can be brought into surface contact along the curved surface, and the stress applied thereto can be dispersed well. If the upper end of the mounting table 31 is formed into a curved surface with an acute angle or a smaller radius of curvature, stress may be concentrated in a part of the folded part of the futon F that abuts on the upper end. If such stress concentration occurs, the part in question may be compressed and the density may increase, resulting in a decrease in breathability and therefore a decrease in drying efficiency. However, since the mounting table 31 has the above-mentioned radius of curvature, such a decrease in drying efficiency can be avoided. Furthermore, since the punching hole group 311 can be formed even on the curved surface, the drying efficiency can also be improved.
[0025] 4 and 5, the base 32 is formed in a hollow, generally rectangular parallelepiped shape, and an opening 321a is formed on the upper surface thereof for connecting the internal space T of the base 32 to the internal space P of the mounting table 31. Meanwhile, an opening 321b is formed on the lower surface of the base 32 for connecting the internal space T to a downward exhaust flow path 281 (described later) formed in the bottom wall 28 of the housing 20. These openings 321a and 321b allow air in the internal space P to flow into the downward exhaust flow path 281 (see FIG. 12).
[0026] As shown in Figures 4 to 6, the base 32 has two front casters 322a spaced apart in the left-right direction on the underside of the front end, and a step 322c recessed upward over substantially the entire left-right area on the underside of the rear end, and two rear casters 322b spaced apart in the left-right direction on the step 322c. The front caster 322a has a larger diameter than the rear caster 322b, and is provided so that its lower end is located lower than the rear caster 322b. The rear caster 322b abuts against the upper surface of the bottom wall 28 of the housing 20 so as to be able to run.
[0027] Behind the front caster 322a of the base 32, an inclined surface 323 is formed which extends in the left-right direction and inclines downward from the front to the rear. When the mounting unit 3 is accommodated in the drying space D, the front end of the inclined surface 323 is located at a position where a support caster 285 (described later) abuts. Due to the formation of this inclined surface 323, the base 32 has a shape which protrudes slightly downward in the region near the opening 321b, specifically from the rear end of the inclined surface 323 to the front end of the step portion 322c, compared to the front and rear ends.
[0028] As shown in FIG. 12, the bottom wall 28 of the housing 20, which forms the running surface of the rear caster 322b, is also formed with an inclined surface 283. The inclined surface 283 has the same inclination angle, inclination direction, and inclination length as the inclined surface 323 of the base 32, and is formed so that the rear end of the inclined surface 283 is located at a position where the rear caster 322b abuts when the mounting unit 3 is accommodated in the drying space D. Therefore, the bottom wall 28 has a shape in which the area in front of the inclined surface 323 protrudes slightly upward. It is preferable to set the heights of the inclined surface 283 and the inclined surface 323 so that a small gap is formed between the area and the area near the opening 321b when the mounting unit 3 is accommodated in the drying space D.
[0029] Further, a caster base 284 having a substantially U-shaped cross section with an open lower portion is provided at the front end of the bottom wall portion 28, and two support casters 285 that abut against the lower surface of the base portion 32 so as to be able to run are provided on the upper surface of the caster base 284 at a distance in the left-right direction. When the mounting portion 3 is accommodated in the drying space D, the support caster 285 is located at the front end of the inclined surface 323 and abuts against the base portion 32 to support it. When the mounting portion 3 is accommodated in the drying space D, the support caster 285 supports the front side of the mounting portion 3, so that in this embodiment, the front caster 322a is slightly spaced from the installation surface of the dryer 1. A notch 286 is formed in the caster base 284 at a corresponding position so as not to contact the front caster 322a of the base portion 32.
[0030] In this way, the inclined surface 283 is formed on the bottom wall 28 corresponding to the rear caster 322b of the base 32, and the inclined surface 323 is formed on the base 32 corresponding to the support caster 285 of the bottom wall 28, so that when the placement unit 3 is pulled out from the drying space D, the casters run on the opposing inclined surfaces at the same time. This allows the base 32 to move upward so as to be separated from the bottom wall 28 by the height of the inclined surface while maintaining the parallelism between the base 32 and the bottom wall 28, and allows stable horizontal movement. In addition, the rear caster 322b and the support caster 285 are disposed at the same position in the left-right direction. Therefore, the support caster 285 restricts the forward movement of the rear caster 322b, so that when the user moves the placement unit 3 forward, the entire placement unit 3 can be prevented from slipping out of the drying space D.
[0031] 12, a downward exhaust passage 281 is defined inside the bottom wall portion 28, and an opening 282 for connecting the downward exhaust passage 281 to the internal space T and an opening 287 for fluidly connecting a vertical passage 271 (described later) to the downward exhaust passage 281 are formed on the upper surface thereof. The opening 282 is formed in a position facing the opening 321b of the base portion 32 and in substantially the same shape as the opening 321b when the mounting portion 3 is accommodated in the drying space D.
[0032] A seal member 288 is provided on the periphery of the opening 282, and when the placement unit 3 is accommodated in the drying space D, the periphery of the opening 321b of the base unit 32 abuts against the seal member 288, and the opening 282 and the opening 321b of the base unit 32 can be airtightly connected via the seal member 288. The seal member 288 is immovably fixed to the bottom wall unit 28 by a fastener such as a screw, an adhesive, or the like, and any material may be used as long as it can airtightly connect the opposing openings. For example, felt, an elastic material, or the like can be used as the seal member 288. The seal member 288 may be provided on the periphery of the opening 321b.
[0033] As described above, the rear casters 322b abut against the bottom wall 28 of the housing 20 and are supported by the support casters 285, so that the mounting unit 3 can move in the front-rear direction relative to the housing 20 and can be housed in and drawn out from the drying space D. Furthermore, when the mounting unit 3 is housed in the drying space D, it can move downward relative to the housing 20 and can connect the opening 321b and the opening 282 airtightly.
[0034] As the mounting unit 3 is pulled out from the drying space D, the rear caster 322b approaches the support caster 285, causing the front side to tilt downward. However, due to this tilt, the front caster 322a comes into contact with the installation surface, and the rear caster 322b is always in contact with the bottom wall 28 of the housing 20, so the mounting unit 3 can travel stably even if it is pulled out to a certain extent.
[0035] The pressing belt 33 is a long, flexible belt-like member provided at both front-rear end portions of the mounting base 31, and each presses the short end portion of the futon F against the mounting surface of the mounting base 31. The pressing belt 33 extends from one side surface in the left-right direction of the mounting base 31 (left side in FIG. 7) via the upper curved surface of the mounting base 31 to the other side surface (right side in FIG. 7), and one longitudinal end portion thereof is fixedly connected to one side surface of the mounting base 31. Meanwhile, a connecting member 331 is provided at the other longitudinal end portion of the pressing belt 33, which can be detachably connected to a connecting device 313 provided on the other side surface of the mounting base 31.
[0036] An example of a connecting mechanism using such a connecting device 313 and connecting member 331 is one that uses a buckle device and a tongue used in seat belts, etc. The tongue is a flat plate member in which holes, notches, etc. are formed, and can be inserted into an insertion opening provided in the buckle device to lock the tongue in the buckle device. On the other hand, the lock of the tongue can be released by pressing the release button of the buckle device. Alternatively, a hook may be used to lock the two together, or a hook-and-loop fastener may be used, and any other connecting mechanism that is detachable may be used.
[0037] In addition, the pressing band 33 has an elastic part 332 formed in a part thereof, which is elastic in the longitudinal direction. As shown in Figs. 7 and 8, when pressing the short-side end of the placed futon F, the pressing band 33 is made to run over the short-side end, so that the pressing band 33 is separated from the placement surface according to the thickness of the futon F, and the connecting member 331 and the connecting device 313 are separated. However, the elastic part 332 can extend by the distance of the separation, thereby connecting the connecting member 331 and the connecting device 313. Furthermore, the elastic part 332 constantly generates a restoring force by connecting the connecting member 331 and the connecting device 313 in the extended state, so that the pressing band 33 can uniformly press the futon F toward the placement surface side by the restoring force. Such elastic part 332 is preferably an elastic member such as a coil spring or a rubber body, and the entire pressing band 33 may be the elastic part 332.
[0038] Jet nozzle 23 shown in Fig. 9 is a nozzle that sprays liquid containing chemicals such as a deodorant, disinfectant, anti-mite agent, etc. The chemicals discharged from jet nozzle 23 are blown into futon F together with the warm air in drying space D, so that futon F can be dried and disinfected at the same time.
[0039] (Flow path and operation in the dryer) The hot air flow path in the dryer will be described with reference to Figs. 10 is a diagram showing the flow direction of hot air flowing from the gas heater 21 to the upper wall portion 25 of the dryer according to the embodiment. In the space formed between the flat plate portion 25a and the upper wall portion 25, which is the intake air flow path 251, the hot air from the gas heater 21 passes through the connection pipe 253 and is sent toward the flat plate portion 25a. Then, a vortex (tornado) is generated in the intake air flow path 251, and the hot air is sent from the inlet hole group 255 to the drying space D.
[0040] Fig. 11 is a diagram showing the flow direction of hot air flowing from the upper wall of the dryer according to the embodiment to the drying space D of the main body. As shown in Fig. 11, the hot air from the intake air flow path 251 also swirls in the drying space D and is sent to the futon F, and the air in the drying space D passes through the futon F via the punched hole groups 311 provided on both side surfaces of the mounting table 31 and is sucked into the mounting part 3.
[0041] FIG. 12 is a side view showing the overall flow of hot air in the dryer according to the embodiment. As shown in FIG. 12, above the upper wall 25 of the housing 20, two flat plate portions 25a and 25b are provided, which extend horizontally and are parallel to each other, and the gas heater 21 and the exhaust fan 22 are placed on the flat plate portion 25b located at the top. The flat plate portion 25a located below the flat plate portion 25b is used as a boundary to divide and define two spaces in the vertical direction, and the space defined between the flat plate portion 25a and the upper wall 25 is used as an intake flow path 251, and the space defined between the flat plate portion 25a and the flat plate portion 25b is used as an upper exhaust flow path 252. The upper exhaust flow path 252 extends slightly rearward from the intake flow path 251 and is fluidically connected to the vertical flow path 271. Since the intake flow path 251 and the upper exhaust flow path 252 are formed vertically with the flat plate portion 25a as a boundary, it is preferable that the flat plate portion 25a is made of a heat insulating material.
[0042] The vertical flow path 271 is a gap between the rear wall portion 27 and the flat plate portion 27a located in front of and parallel to the rear wall portion 27, and is formed as a space having a rectangular cross section that is elongated in the left-right direction when viewed from above and extends in the up-down direction. The vertical flow path 271 is fluidly connected to the upper exhaust flow path 252 and the lower exhaust flow path 281, which together form one exhaust flow path.
[0043] 10, a connection pipe 253 is connected to the intake flow path 251, and a connection pipe 254 is connected to the upward exhaust flow path 252. The connection pipe 253 is formed corresponding to the gas heater 21, and is fluidly connected to the intake flow path 251, thereby enabling air heated by the gas heater 21 to be sucked into the intake flow path 251. The connection pipe 254 is formed corresponding to the exhaust fan 22, and is fluidly connected to the upward exhaust flow path 252, thereby enabling the exhaust fan 22 to exhaust air from the upward exhaust flow path 252.
[0044] Further, in the upper wall portion 25, a group of inflow holes 255 is formed as air vents that communicate the intake passage 251 with the drying space D and allow air heated by the gas heater 21 to flow into the drying space D. The group of inflow holes 255 is a plurality of punched holes, and is formed over a predetermined range in the left-right direction and the front-rear direction of the entire drying space D. The predetermined range here refers to substantially the entire lower region of the intake passage 251, and more specifically, the range from above the rear end of the mounting table 31 in the front-rear direction to the front end of the intake passage 251 in the front-rear direction.
[0045] Next, a method of using the dryer 1 will be described. First, the placement section 3 is pulled out from the drying space D, and the futon F is placed on the placement surface. Then, the placement section 3 is moved rearward in the front-rear direction by a predetermined distance so that the door section 29 can be closed. This movement causes the rear wheel caster 322b and the support caster 285 to run on the opposing surfaces including the corresponding inclined surfaces, and the opening 321b of the base section 32 and the opening 282 of the bottom wall section 28 approach each other and are connected to each other via the seal member 288. In this state, the door section 29 can be closed and the placement section 3 can be completely accommodated in the drying space D. When the placement section 3 is completely accommodated in the drying space D, the internal spaces P, T of the placement section 3 and the downward exhaust flow path 281 are fluidically connected, and therefore the internal spaces P, T and the upward exhaust flow path 252 are fluidically connected.
[0046] After placing the placement unit 3 in the drying space D, the user controls the control unit 24 to operate the exhaust fan 22, and the air in the upward exhaust flow path 252 is discharged to the outside, causing the internal spaces P and T in the placement unit 3 to become negative pressure via the vertical flow path 271 and the downward exhaust flow path 281. When the internal spaces P and T become negative pressure, the air in the drying space D passes through the futon F via the punching hole groups 311 provided on both side surfaces of the placement table 31 and is sucked into the placement unit 3. In response to this, the drying space D becomes negative pressure, and air outside the dryer 1 passing through the gas heater 21 is sucked into the drying space D via the intake air flow path 251 connected to the drying space D by the inlet hole group 255.
[0047] When the gas heater 21 is operating in a state where air flows into the drying space D, the air heated by the gas heater 21 warm This will flow into the drying space D as wind, warm The air passes through the mat-like material F placed on the placement section 3, flows into the placement section 3, and is then discharged to the outside of the dryer 1, thereby drying the futon F.
[0048] As described above, the dryer of the embodiment includes the housing 20 in which the drying space D is formed, the placement unit 3 that is provided in the drying space D and on which the mat-like member F can be placed on the placement surface, and warm The gas heater 21 blows air into the mat-like member F from multiple directions. warm It is provided with a wind direction control means for controlling the wind direction.
[0049] The airflow direction control means of the embodiment is realized by an upper wall portion 251 located at the top of the drying space, a connecting pipe 253 that guides warm air from the gas heater 21 into the upper wall portion 251, and a group of inlet holes 255 provided in the upper wall portion 251.
[0050] In the embodiment, in the intake air flow path formed by the upper wall portion 251 and the flat plate portion 25a provided above the upper wall portion 251, the hot air can be sent from the inlet hole group 255 to the drying space D while swirling.
[0051] In the embodiment, in the drying space D, the warm air from the intake flow path swirls and is sent to the mat-shaped member F, and the warm air in the drying space D passes through the mat-shaped member F and is sucked into the mounting section 3 through a group of punching holes 311 provided on both side surfaces of the mounting table 31.
[0052] In the embodiment, when the mounting portion 3 is stored in the housing 20, it further includes a base portion 32 having a second opening 321b at a position opposite to a first opening 321a provided on the bottom surface of the mounting portion 3, and an exhaust fan 22, and warm air is sucked from the base portion 32 into the exhaust fan 22 and released.
[0053] In the embodiment, the dryer comprises a housing 20 in which a drying space D is defined, a mounting section 3 that is accommodated in the drying space D of the housing 20, on both side mounting surfaces on which a mat-like member F can be placed and on which a group of holes 311 is provided, and which defines an internal space P, and an air blowing means 21 that sends warm air into the drying space D of the housing 20, in which the warm air sent into the drying space D passes through the mat-like member F and is sucked into the internal space P via the group of holes 311 provided on the mounting surfaces on both sides, and in areas 311a, 311b, 311c where the peripheral end of the mat-like member F of the mounting section 3 is located, no group of holes 311 is formed to prevent warm air from leaking, thereby improving the adhesion of the peripheral end. In this embodiment, the hole diameter of the hole group 311 on the drying space D side is larger than the hole diameter on the internal space P side, so that the hot air passes through the mat-like member F easily. In this embodiment, the upper end of the mounting section 3 is formed with a curved surface having holes 311 except for areas 311a and 311b, and the radius of curvature of the curved surface is at least 0.9 times the thickness of the mat-like member F to be placed thereon, so that the folded portion of the futon F can be brought into surface contact along the curved surface, and the stress applied thereto can be dispersed well. Since the mounting table 31 has the above-mentioned radius of curvature, such a decrease in drying efficiency can be avoided. Furthermore, since the holes 311 can be formed even on the curved surface, the drying efficiency can also be improved. In this embodiment, the area on both sides of the placement surface is 60 mm to 150 mm, so that the adhesion of the peripheral edge of the futon F in the short direction can be improved. In this embodiment, the area below the placement surface is 100 mm to 250 mm, so that the adhesion of the peripheral edge of the comforter F in the longitudinal direction can be improved. In the embodiment, the mounting surface is formed by a plurality of metal plates, and the joints of the metal plates are bent toward the internal space, thereby enhancing the strength of the joints of the metal plates.
[0054] According to the dryer of the embodiment, the hot air forms a vortex (tornado) in the intake air flow path 251 and is sent from the inlet hole group 255 to the drying space D. The hot air from the intake air flow path 251 also forms a vortex in the drying space D and is sent to the futon F, and the air in the drying space D passes through the futon F via the punched hole groups 311 provided on both sides of the mounting table 31 and is sucked into the mounting section 3, so that the futon can be dried efficiently.
[0055] In the present embodiment described above, the object to be dried has been described as a futon F, but this is not limited to this, and other mat-like members made of fibrous material formed into a mat shape, such as carpets, rugs, mattresses, etc., may also be placed on the surface to be dried.
[0056] In addition, although the punched hole group 311 and the inlet hole group 255 are described as being circular holes, the present invention is not limited thereto and may be rectangular holes. Furthermore, the placement surface may be formed in a mesh shape to communicate the internal space P and the drying space D.
[0057] The flow path may be reversed by exchanging the positions of the gas heater 21 and the exhaust fan 22. In this case, the heated air from the mounting table 31 flows into the futon F, and the air that passes through this flows into the inlet hole group 255.

These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims.
