When using the movable mounting section 3, the user opens the door section 29, moves the movable mounting section 3 accommodated in the drying space D forward, and pulls out the movable mounting section 3 from the drying space D to some extent. , put a futon on it. After the placement, the movable placement section 3 is moved backward (accommodating direction) to be accommodated in the drying space D again, and the door section 29 is closed. Thereafter, the user can operate the operation panel 241 to cause the dryer 1 to perform a desired drying operation, thereby drying the futon.

In addition, the bottom wall portion 28 of the housing 20 functions as a part of the traveling path when the movable mounting portion 3 is moved back and forth, and when the movable mounting portion 3 is accommodated in the drying space D, function as an exhaust flow path. The bottom wall portion 28 will be described in detail later together with the description of the configuration of the movable mounting portion 3 below.

(Movable placing portion 3)
The configuration of the movable mounting section 3 will be described in detail. 4 to 6 are a perspective view, a front view, and a side view, respectively, showing the configuration of the movable placement section. FIG. 7 is a cross-sectional view showing a longitudinal section of one hole in the group of punched holes provided in the movable mounting portion, and FIG. 8 shows a modification thereof. 9 and 10 are a front view and a side view, respectively, showing the movable placing portion on which the futon is placed. 11 is a cross-sectional view taken along line AA of FIG. 2, and FIG. 12 is a plan view of the bottom wall portion of the housing. 13A and 13B are diagrams for explaining the ventilation holes of the pressing band provided in the movable mounting portion. FIG. The movable mounting portion 3 includes a mounting table 31, a pedestal portion 32, and a pressing band 33, as shown in FIGS.

As a whole, the mounting table 31 is formed in a hollow triangular prism shape with the top surface and the bottom surface facing in the front-rear direction, and one side facing the apex formed at the most acute angle facing downward. 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 rear surface of the mounting table 31, and one side of the triangular prism facing downward is the bottom surface of the mounting table 31. do. The other two inclined side surfaces and the curved surface formed at the upper end are used as the mounting surface of the mounting table 31 . Therefore, the mounting surface has a shape obtained by bending a plane so that a virtual bending line facing the front-rear direction is positioned at the upper end. The bottom surface of the mounting table 31 is connected to the top surface of the pedestal portion 32 .

As shown in FIG. 6, on both side surfaces of the mounting table 31, there are provided punched hole groups 311 consisting of a plurality of circular holes communicating between the internal space P (see FIG. 11) of the mounting table 31 and the drying space D. be done. Air flows between the drying space D and the internal space P through the 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 half or more of the longitudinal width of the futon.

As shown in FIG. 7 , each hole of the punching hole group 311 has a peripheral edge on the side of the drying space D, that is, the side (upper side in the figure) in contact with the futon F, which expands in diameter toward the drying space D side. A curved surface 311a is formed as shown in FIG. Therefore, each hole of the punched hole group 311 has an opening diameter (hole diameter) on the dry space D side larger than an opening diameter on the internal space P side. It is preferable that the punched hole group 311 having the curved surface 311a formed on the peripheral portion thereof has an opening diameter of 5 to 8φ on the inner space P side. In addition, as shown in FIG. 8, each hole of the punching hole group 311 may form a curved surface 311a over not only the peripheral edge but also the entire depth direction, and instead of the curved surface 311a, the hole faces toward the drying space D. A tapered surface may be formed so that the diameter increases as the diameter increases.

In addition, a grip portion 312 is provided on the front surface of the mounting table 31 to be gripped by the user when moving the movable mounting portion 3 .

When placing the bedding F to be dried on the mounting table 31, as shown in FIGS. It is mounted on the mounting surface of the mounting table 31 . At this time, the futon F is folded along the inclination of the placement surface.

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 as large as the thickness of the bedding F to be mounted. By forming a curved surface having such a radius of curvature, when the futon F is folded and placed, the folded portion of the futon F can be brought into surface contact along the curved surface, and the stress applied thereto can be well reduced. can be distributed in 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 concentrate on a part of the folded portion of the futon F that contacts the upper end. When such stress concentration occurs, the part concerned is compressed and the density increases, which may reduce air permeability and, in turn, reduce drying efficiency. However, since the mounting table 31 has the radius of curvature described above, such a decrease in drying efficiency can be avoided. Furthermore, since the punching hole group 311 can be formed even on a curved surface, it is possible to improve the drying efficiency.

As shown in FIGS. 4 and 11, the pedestal portion 32 is formed in a hollow substantially rectangular parallelepiped shape, and an opening portion 321a for connecting the internal space T and the internal space P of the mounting table 31 is formed on the upper surface. formed. On the other hand, an opening 321b is formed in the lower surface of the pedestal 32 to connect the internal space T with a later-described lower exhaust flow path 281 formed in the bottom wall 28 of the housing 20 . These openings 321 a and 321 b allow air in the internal space P to flow into the lower exhaust flow path 281 .

The base portion 32 has two front wheel casters 322a spaced apart in the left-right direction on the bottom surface of the front end thereof, and a stepped portion 322c that is recessed upward over substantially the entire width in the left-right direction on the bottom surface of the rear end portion. , two rear wheel casters 322b are spaced apart in the left-right direction on the stepped portion 322c. The front-wheel caster 322a is formed to have a larger diameter than the rear-wheel caster 322b, and is provided so that its lower end is located below the rear-wheel caster 322b. The rear wheel casters 322b are in contact with the upper surface of the bottom wall portion 28 of the housing 20 so as to be able to travel.

An inclined surface 323 extending in the left-right direction and inclined downward from the front to the rear is formed behind the front wheel caster 322a in the base portion 32 . The front end portion of the inclined surface 323 is located at a position where the supporting casters 285 (to be described later) come into contact with the inclined surface 323 when the movable placing section 3 is housed in the drying space D. FIG. By forming this inclined surface 323, the pedestal portion 32 has a larger area near the opening 321b than its front end and rear end, more specifically, from the rear end of the inclined surface 323 to the stepped portion 322c. It has a shape that protrudes slightly downward toward the front end.

As shown in FIGS. 11 and 12, the bottom wall portion 28 of the housing 20 forming the running surface of the rear wheel caster 322b is similarly formed with an inclined surface 283. As shown in FIGS. The inclined surface 283 has the same inclination angle, inclination direction, and inclination length as those of the inclined surface 323 of the pedestal portion 32 . The rear end of the inclined surface 283 is positioned at the position where the 322b abuts. Therefore, the bottom wall portion 28 has a shape in which a region in front of the inclined surface 323 slightly protrudes upward. The heights of the inclined surface 283 and the inclined surface 323 are set so that a slight gap is formed between this area and the area near the opening 321b when the movable placing section 3 is accommodated in the drying space D. preferably.

Further, at the front end of the bottom wall portion 28, a caster base 284 having a substantially U-shaped cross section with an open bottom is provided. Casters 285 are spaced apart in the left-right direction. The support casters 285 are positioned at the front end of the inclined surface 323 and abut against and support the pedestal 32 when the movable mounting section 3 is accommodated in the drying space D. As shown in FIG. Since the front side of the movable mounting section 3 is supported by the support casters 285 when the movable mounting section 3 is accommodated in the drying space D, the front wheel casters 322a are moved from the installation surface of the dryer 1 in this embodiment. They are slightly separated. A notch 286 is formed in the caster base 284 at a corresponding position so as not to contact the front wheel caster 322 a of the base portion 32 .

Thus, the slanted surface 283 is formed on the bottom wall portion 28 corresponding to the rear wheel caster 322 b of the pedestal portion 32 , and the slanted surface 323 is formed on the pedestal portion 32 corresponding to the support caster 285 of the bottom wall portion 28 . As a result, when the movable placing section 3 is pulled out from the drying space D, the respective casters simultaneously run on the facing inclined surfaces. As a result, the pedestal 32 can be moved upwardly away from the bottom wall 28 by the height of the inclined surface while maintaining parallelism between the pedestal 32 and the bottom wall 28. Can move horizontally. Also, the rear wheel caster 322b and the support caster 285 are arranged at the same position in the left-right direction. Therefore, since the forward movement of the rear wheel casters 322b is restricted by the support casters 285, when the user moves the movable mounting section 3 forward, the movable mounting section 3 as a whole does not slip out of the drying space D. can be prevented.

Further, as shown in FIGS. 11 and 12, the bottom wall portion 28 has a lower exhaust flow path 281 defined therein, and an opening for connecting the lower exhaust flow path 281 and the internal space T on the upper surface thereof. A portion 282 and an opening 287 positioned behind the opening 282 for fluidly connecting a vertical flow path 271 and a lower exhaust flow path 281 are formed. The opening 282 is formed at a position facing the opening 321b of the pedestal 32 and having substantially the same shape when the movable placing section 3 is accommodated in the drying space D. As shown in FIG.

A seal member 288 is provided at the periphery of the opening 282, and when the movable mounting section 3 is housed in the drying space D, the periphery of the opening 321b of the pedestal 32 abuts against the seal member 288. The opening 282 and the opening 321b of the pedestal 32 can be airtightly connected via the sealing member 288. As shown in FIG. The sealing member 288 is immovably fixed on the bottom wall portion 28 by a fastener, an adhesive, or the like on a screw or the like. good. For example, felt, an elastic member, or the like can be used as the sealing member 288 . Note that the seal member 288 may be provided on the peripheral edge of the opening 321b.

As described above, the rear wheel casters 322b contact the bottom wall portion 28 of the housing 20, and the movable mounting section 3 is supported by the support casters 285, thereby moving relative to the housing 20 in the front-rear direction. storage and withdrawal from the drying space D are possible. Further, the movable mounting portion 3 can relatively move downward when accommodated in the drying space D, and the opening 321b and the opening 282 can be airtightly connected.

As the movable placing section 3 is pulled out from the drying space D, the rear wheel caster 322b approaches the support caster 285 and the front side is inclined downward. However, due to the inclination, the front wheel caster 322a is grounded on the installation surface, and the rear wheel caster 322b is always grounded on the bottom wall part 28 of the housing 20. The placing section 3 can be stably run.

The pressing belts 33 are long, flexible belt-like members provided at both ends of the mounting table 31 in the front-rear direction, and press the ends of the futon F in the width direction against the mounting surface of the mounting table 31 . The pressing band 33 extends from one side surface (left side in FIG. 9) of the mounting table 31 to the other side surface (right side in FIG. 9) via the upper curved surface of the mounting table 31, and extends in the longitudinal direction thereof. One end is fixedly connected to one side surface of the mounting table 31 . On the other hand, a connecting member 331 that can be detachably connected to a connecting device 313 provided on the other side surface of the mounting table 31 is provided at the other longitudinal end of the pressing band 33 .

As a connection mechanism using such a connection device 313 and a connection member 331, there is a mechanism using a buckle device and a tongue used for a seat belt or the like. The tongue is a flat plate member having holes, notches, etc., and can be locked in the buckle device by inserting the tongue into an insertion opening provided in the buckle device. On the other hand, the locking of the tongue can be released by pressing the release button of the buckle device. In addition, hooks may be used to engage each other, hook-and-loop fasteners may be used, and any detachable connection mechanism may be used.

Further, the pressing band 33 is partially formed with a stretchable portion 332 that is stretchable in the longitudinal direction. As shown in FIGS. 9 and 10, when pressing the lateral end of the placed bedding F, the pressing band 33 is laid over the lateral end of the bedding F. Therefore, the thickness of the bedding F Accordingly, the pressing band 33 is separated from the mounting surface, and the connecting member 331 and the connecting device 313 are separated. However, the connecting member 331 and the connecting device 313 can be connected by extending the expansion/contraction part 332 by the separation distance. Furthermore, the elastic portion 332 always generates a restoring force by connecting the connecting member 331 and the connecting device 313 in an extended state, and the restoring force causes the pressing band 33 to uniformly place the futon F on the placing surface side. can be pressed. Such a stretchable portion 332 is preferably a member having elasticity such as a coil spring or a rubber body, and the entire pressing band 33 may be used as the stretchable portion 332 .

Further, as shown in FIG. 13, the press band 33 is uniformly provided with a group of ventilation holes 333 including the stretchable portion 332, so that the blanket F in contact with the press band 33 can be ventilated. In FIG. 13, the ventilation hole groups 333 are formed in circular holes with a large gap between the holes. may

(Flow path and operation in the dryer)
Flow paths in the dryer will be described with reference to FIGS. 11, 14, and 15. FIG. 14 and 15 are sectional views taken along line BB and line CC of FIG. 11, respectively. 11, the connection pipes 253, 254 and a part of the connection pipe 231, which are arranged at different positions in the left-right direction from the cut surface, are virtually indicated by dashed lines. Similarly, in FIG. 14, the connection pipes 253 and 231 located above the cut plane are virtually indicated by a dashed line, and in FIG. are shown. Also, the dotted arrows shown in these figures indicate the direction of air flow.

As shown in FIG. 11, two flat plate portions 25a and 25b extending horizontally and parallel to each other are provided above the upper wall portion 25 of the housing 20, and the uppermost flat plate portion is provided. A gas heater 21, an exhaust fan 22, and a mist generator 23 are placed on 25b. Two spaces are defined by dividing the flat plate portion 25a located below the flat plate portion 25b in the vertical direction, and the space defined between the flat plate portion 25a and the upper wall portion 25 is A space defined between the flat plate portion 25 a and the flat plate portion 25 b is used as the upper exhaust flow channel 252 . The upper exhaust channel 252 extends slightly rearward from the intake channel 251 and fluidly connects with the vertical channel 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, the flat plate portion 25a is preferably made of a heat insulating member.

The vertical flow path 271 is a gap between the rear wall portion 27 and the flat plate portion 27a parallel to the rear wall portion 27 and positioned forward. It is formed as an extended space. The vertical channel 271 is fluidly connected to the upper exhaust channel 252 and the lower exhaust channel 281, which together form one exhaust channel.

As shown in FIGS. 11, 14, and 15, a connection pipe 253 is connected to the intake flow path 251, and a connection pipe 254 is connected to the upper exhaust flow path 252. As shown in FIGS. The connection pipe 253 is formed corresponding to the gas heater 21 and is fluidly connected to the air intake passage 251 so that the air heated by the gas heater 21 can be drawn into the air intake passage 251 . The connection pipe 231 has one end connected to the liquid storage tank of the fog generating section 23 and the other end connected to the connection pipe 253 so that the fog generated by the fog generating section 23 passes through the connection pipe 253 to the intake flow path. 251. The connection pipe 254 is formed corresponding to the exhaust fan 22 and is fluidly connected to the upper exhaust flow path 252 so that the air in the upper exhaust flow path 252 can be discharged by the exhaust fan 22 .

Further, the upper wall portion 25 is formed with an inflow hole group 255 as a vent hole that communicates the air intake passage 251 with the drying space D and allows the air heated by the gas heater 21 to flow into the drying space D. The inflow hole group 255 is a plurality of punched holes, and is formed over the entire length of the drying space D in the left-right direction and a predetermined range in the front-rear direction. Here, the predetermined range is substantially the entire lower region of the air intake passage 251, and more specifically, from above the rear end of the mounting table 31 in the front-rear direction to the front end of the air intake passage 251 in the front-rear direction. Range. Details of the effect of the inflow hole group 255 formed in the predetermined range will be described later.

Next, how to use the dryer 1 will be described. First, the movable placement section 3 is pulled out from the drying space D, and the futon F is placed on its placement surface. move. By this movement, the rear wheel caster 322b and the support caster 285 run on opposing surfaces including corresponding inclined surfaces, and the opening 321b of the base portion 32 and the opening 282 of the bottom wall portion 28 approach each other, and the seal member Via 288 these openings are connected. In this state, the door portion 29 can be closed and the movable placing portion 3 can be completely accommodated in the drying space D. As shown in FIG. When the movable mounting section 3 is completely accommodated in the drying space D, the internal spaces P, T of the movable mounting section 3 and the lower exhaust flow path 281 are fluidly connected. It is fluidly connected to the exhaust flow path 252 .

After the movable mounting section 3 is accommodated in the drying space D, when the user controls the control section 24 to operate the exhaust fan 22, the air in the upper exhaust flow path 252 is discharged to the outside. Via the vertical channel 271 and the downward exhaust channel 281, the internal spaces P and T in the movable mounting section 3 become negative pressure. When the internal spaces P and T become negative pressure, the air in the drying space D passes through the bedding F through the punched hole groups 311 provided on both side surfaces of the mounting table 31 and is sucked into the movable mounting section 3 . be. Accordingly, the inside of the drying space D becomes negative pressure, and the air outside the dryer 1 passing through the gas heater 21 flows into the drying space D through the air intake passage 251 that communicates with the drying space D through the inflow hole group 255. be inhaled.

When the gas heater 21 is operating while air is flowing into the drying space D, the air heated by the gas heater 21 flows into the drying space D as hot air. The bedding F is dried by being discharged to the outside of the dryer 1 after passing through the placed bedding F and flowing into the movable placing section 3 .

In a state in which air flows into the drying space D, when the fog generating section 23 is operating, the air containing the fog generated by the fog generating section 23 enters the drying space D through the connection pipe 253 and the intake flow path 251. The fog-containing air flows into D, and passes through the futon F, allowing chemicals such as deodorants, disinfectants, and anti-mite agents to permeate into the futon F. The drug distribution can be automated.

(Effect of Inflow Hole Group Formed in Predetermined Range)
The effect obtained by the group of inlet holes formed in a predetermined range in the upper wall portion of the housing will be described.

As described above, the hot air, which is the air heated by the gas heater 21, flows into the drying space D from the inflow hole group 255. Therefore, when the inflow hole group 255 is formed closer to the front end side, the hot air is positioned right below it. The futon part becomes hot, but the futon part located on the rear end side, for example, has a lower temperature.

On the other hand, as shown in FIGS. 11 and 14, the inflow hole group 255 is formed over a predetermined range of the upper wall portion 25 as described above, so that the inflow hole group 255 is positioned above one end of the mounting table 31 in the front-rear direction. The hot air flowing from above can be blown down on the futon F in a wider range, and the temperature distribution in the drying space D can be made more uniform in the front-rear direction, as compared with the case where only the drying space D is formed. By equalizing the temperature distribution in this way, it is possible to reduce the temperature unevenness of the futon F.

As shown in FIGS. 11 and 14 , in this embodiment, the control unit 24 is arranged in front of the air intake passage 251 , so the air intake passage 251 does not extend above the front end of the mounting table 31 . not It is needless to say that even with such a configuration, it is possible to reduce unevenness in temperature compared to a configuration in which hot air is blown down only from a portion. The air supply channel 251 extends above the front end of the mounting table 31, so that the intake channel 251 extends to completely cover the upper side of the mounting table 31 (for example, extends below the control unit 24). By doing so, hot air can be blown down over the entire area of the mounting table 31 in the front-rear direction, and the temperature unevenness of the bedding F can be further reduced.

In this embodiment, since the connection pipe 253 is connected to the rear of the intake flow path 251, it is desirable that the opening ratio of the inflow hole group 255 is larger on the front side than on the rear side. By doing so, the temperature distribution in the drying space D can be made more uniform.

In the present embodiment, the futon to be dried has been described as being the futon F, but it is not limited to this. It may be dried.

Further, although the punching hole group 311 and the inflow hole group 255 are described as being circular holes, they may be square holes, and the placement surface and the upper wall portion 25 are formed in a mesh shape, and the mesh openings are formed. It may correspond to the punching hole group 311 or the inflow hole group 255 .

Also, the positions of the gas heater 21 and the exhaust fan 22 may be exchanged and the flow paths may be reversed. In this case, the heated air from the mounting table 31 flows into the futon F, and the air that has passed through this flows into the inflow hole group 255 .

Embodiments of the invention are provided by way of example and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, replacements, and modifications can be made without departing from the scope of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the scope of the invention described in the claims and its equivalents.
