A drying space D is defined inside. The movable mounting section 3 can be accommodated within this drying space D.

The door section 29 is attached to one side wall section 26 with a hinge or the like so that it can be opened and closed, and allows the movable mounting 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 window section 291 made of, for example, glass or the like and has light transmittance, and is further provided with a grip section 292 for the user to open and close the door section 29 .

The gas heater 21 is provided above the upper wall portion 25 and at the rearmost part of the casing 20, has a gas burner, heats air, and connects a connecting pipe 253 (see FIG. 3) to an intake flow path, which will be described later. 251 (see FIG. 11) is supplied with heated air. Note that the gas heater 21 may be replaced by another device that heats air using another method.

The exhaust fan 22 is provided in front of the gas heater 21, has a check damper 221 for preventing backflow of air, sucks air in the drying space D, and discharges it to the outside via the check damper 221. .

The mist generation unit 23 is provided between the gas heater 21 and the exhaust fan 22, and includes a liquid storage tank in which liquid containing a deodorant, a disinfectant, an anti-mite agent, etc. is stored, and this liquid storage tank. The ultrasonic atomizer is configured as an ultrasonic atomizer including an ultrasonic vibrator that is provided at the bottom of the tank and generates ultrasonic waves in the liquid stored in the liquid storage tank. The liquid storage tank is fluidly connected to an intake flow path 251 (see FIG. 11), which will be described later, by a connecting pipe 231.

The control unit 24 is provided in front of the exhaust fan 22, that is, in the frontmost part of the housing 20, and has an operation panel 241 for the user to issue instructions regarding the operation of the dryer 1. Installed to face forward. The control unit 24 controls the operations of the gas heater 21 , exhaust fan 22 , and fog generation unit 23 based on operations performed on the operation panel 241 .

The movable mounting section 3 is configured to be movable in the front-rear direction. When using the movable platform 3, the user opens the door 29, moves the movable platform 3 housed in the drying space D forward, and pulls out the movable platform 3 from the drying space D to some extent. , place the futon on top of it. After placement, the movable placement section 3 is moved rearward (accommodation direction) and 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 part 28 of the housing 20 functions as a travel path for a part of the movable placement part 3 when it is moved back and forth, and also functions as a travel path for a part of the movable placement part 3 when it is accommodated in the drying space D. functions as an exhaust flow path. This bottom wall portion 28 will be described in detail later in conjunction with the next description of the configuration of the movable mounting portion 3.

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

The mounting table 31 as a whole is formed into a hollow substantially triangular prism shape, which is laid down so that the top surface and bottom surface face in the front-rear direction, and one side surface opposite to the apex formed at the most acute angle faces downward. In the following description, the front side of the top and bottom surfaces of the triangular prism will be referred to as the front side of the mounting table 31, the other side will be referred to as the back surface of the mounting table 31, and one side of the triangular prism facing downward will be referred to as the bottom surface of the mounting table 31. do. Further, 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 in which the plane is bent so that the virtual bending line facing in the front-rear direction is located at the upper end. The bottom surface of the mounting table 31 is connected to the top surface of the pedestal section 32.

As shown in FIG. 6, punching hole groups 311 are provided on both sides of the mounting table 31 and are formed of a plurality of circular holes that communicate the internal space P of the mounting table 31 (see FIG. 11) and the drying space D. It will be done. Air flows between the drying space D and the interior space P through the punched hole group 311. These punching hole groups 311 are provided over a predetermined distance from the top end of the mounting table 31, and this predetermined distance is preferably half or more of the width in the longitudinal direction of the futon.

As shown in FIG. 7, the diameter of each hole in the punching hole group 311 increases as it goes toward the drying space D side, that is, the side where the futon F comes into contact (upper side in the figure). A curved surface 311a is formed as shown in FIG. Therefore, in each hole of the punching hole group 311, the opening diameter (hole diameter) on the drying space D side is larger than the opening diameter on the internal space P side. It is preferable that the punching hole group 311 having the curved surface 311a formed on the peripheral edge 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 not only at the peripheral edge but also over the entire depth direction. A tapered surface may be formed so that the diameter increases as the diameter increases.

Moreover, a grip part 312 is provided on the front side of the mounting table 31 for the user to grip when moving the movable mounting part 3.

When placing the futon F to be dried on the mounting table 31, as shown in FIG. 9 and FIG. It is placed on the mounting surface of the mounting table 31. At this time, the futon F is folded along the slope of the placement surface.

The upper end of the mounting table 31 is formed into a curved surface, and the radius of curvature is preferably at least 0.9 times the thickness of the futon F to be mounted. By forming a curved surface with such a radius of curvature, when the futon F is folded and placed, the folded part of the futon F can be brought into surface contact along the curved surface, and the stress applied there can be effectively reduced. can be dispersed into If the upper end of the mounting table 31 is formed into an acute angle or a curved surface with a smaller radius of curvature, stress may be concentrated on a part of the folded portion of the futon F that comes into contact with the upper end. When such stress concentration occurs, the area 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 above-described radius of curvature, such a decrease in drying efficiency can be avoided. Furthermore, since the punching hole group 311 can be formed even on a curved surface, drying efficiency can also be improved.

As shown in FIGS. 4 and 11, the pedestal part 32 is formed into a hollow substantially rectangular parallelepiped shape, and has an opening 321a on the top surface for connecting the internal space T and the internal space P of the mounting table 31. It is formed. On the other hand, an opening 321b is formed in the lower surface of the pedestal 32 to connect the internal space T to a lower exhaust flow path 281, which will be 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 lower exhaust flow path 281.

The pedestal part 32 has two front wheel casters 322a spaced apart from each other in the left-right direction on the lower surface of its front end, and a stepped part 322c recessed upward over substantially the entire area in the left-right direction on the lower surface of its rear end. , two rear wheel casters 322b are provided at the stepped portion 322c so as to be spaced apart from each other in the left-right direction. The front wheel casters 322a are formed to have a larger diameter than the rear wheel casters 322b, and are provided so that their lower ends are located below the rear wheel casters 322b. The rear wheel casters 322b are in movable contact with the upper surface of the bottom wall portion 28 of the housing 20.

Behind the front wheel casters 322a in the base portion 32, an inclined surface 323 is formed which extends in the left-right direction and which slopes downward from the front toward the rear. When the movable placement unit 3 is housed in the drying space D, the front end of the sloped surface 323 is located at a position where support casters 285, which will be described later, come into contact with the sloped surface 323. By forming this inclined surface 323, the pedestal section 32 has a region near the opening 321b compared to its front end and rear end, specifically, from the rear end of the inclined surface 323 to the stepped section 322c. It has a shape that slightly protrudes downward toward the front end.

As shown in FIGS. 11 and 12, an inclined surface 283 is similarly formed on the bottom wall portion 28 of the housing 20 that forms the running surface of the rear wheel caster 322b. The inclined surface 283 has the same inclination angle, direction, and inclination length as the inclined surface 323 of the pedestal section 32, and when the movable mounting section 3 is accommodated in the drying space D, the rear wheel casters The rear end of the inclined surface 283 is located at the position where the inclined surface 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 sloped surface 283 and the sloped surface 323 are set so that when the movable mounting section 3 is housed in the drying space D, a slight gap is formed between the region and the region near the opening 321b. It is preferable to do so.

Further, at the front end of the bottom wall section 28, a caster stand 284 having a generally U-shaped cross section and open at the bottom is provided, and on the upper surface thereof, two supports that come into contact with the lower surface of the pedestal section 32 so as to be movable are provided. Casters 285 are provided spaced apart in the left-right direction. The support caster 285 is located at the front end of the inclined surface 323 and abuts on and supports the pedestal 32 when the movable mounting section 3 is accommodated in the drying space D. When the movable placement unit 3 is housed in the drying space D, the front side of the movable placement unit 3 is supported by the support casters 285. Therefore, in this embodiment, the front wheel casters 322a are moved from the installation surface of the dryer 1. They are spaced slightly apart. A notch 286 is formed in the caster base 284 at a corresponding position so as not to contact the front wheel caster 322a of the base portion 32.

In this way, the inclined surface 283 is formed on the bottom wall section 28 corresponding to the rear wheel caster 322b of the pedestal section 32, and the inclined surface 323 is formed on the pedestal section 32 corresponding to the support caster 285 of the bottom wall section 28. As a result, when the movable mounting section 3 is pulled out from the drying space D, the casters simultaneously run on the opposing inclined surfaces. As a result, the pedestal part 32 can be moved upward away from the bottom wall part 28 by the height of the inclined surface while maintaining the parallelism between the pedestal part 32 and the bottom wall part 28. Can move horizontally. Furthermore, the rear wheel casters 322b and the support casters 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 placement section 3 forward, the entire movable placement section 3 may 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. 282, and an opening 287 located behind the opening 282 for fluidly connecting a vertical flow path 271 and a lower exhaust flow path 281, which will be described later. The opening 282 is formed at a position facing the opening 321b of the pedestal section 32 and having substantially the same shape when the movable placing section 3 is accommodated in the drying space D.

A sealing member 288 is provided at the periphery of the opening 282, and when the movable placing part 3 is accommodated in the drying space D, the periphery of the opening 321b of the pedestal 32 comes into contact with the sealing member 288, The opening 282 and the opening 321b of the pedestal 32 can be airtightly connected via the seal member 288. The sealing member 288 is immovably fixed on the bottom wall 28 by screws, fasteners, adhesives, etc., and any material can be used as long as it can airtightly connect the opposing openings. good. For example, felt, an elastic member, or the like can be used as the seal member 288. Note that the seal member 288 may be provided at the peripheral edge of the opening 321b.

As described above, the movable mounting unit 3 is moved relative to the housing 20 in the front-rear direction by the rear wheel casters 322b coming into contact with the bottom wall 28 of the housing 20 and being supported by the support casters 285. It is possible to accommodate and draw out the drying space D. Furthermore, when the movable mounting section 3 is accommodated in the drying space D, it can move relatively downward, and the opening 321b and the opening 282 can be connected airtightly.

In addition, as the movable mounting part 3 is pulled out from the drying space D, the rear wheel casters 322b approach the support casters 285, and the front side thereof is inclined downward. However, due to the inclination, the front wheel casters 322a come into contact with the installation surface, and the rear wheel casters 322b are always in contact with the bottom wall 28 of the housing 20, so even if the movable mounting section 3 is pulled out to a certain extent, it cannot move. The mounting section 3 can be run stably.

The pressing bands 33 are flexible elongated band-like members provided at both ends of the mounting table 31 in the front and rear directions, and press the ends of the futon F in the lateral direction against the mounting surface of the mounting table 31, respectively. The pressure band 33 extends from one side surface (left side in FIG. 9) of the mounting table 31 in the left-right direction 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. One end portion is fixedly connected to one side 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 of the mounting table 31 is provided at the other end of the pressing band 33 in the longitudinal direction.

An example of a connection mechanism using such a connection device 313 and connection member 331 is one using a buckle device and a tongue used in seat belts and the like. The tongue is a flat plate member in which a hole, a notch, etc. are formed, and the tongue can be locked in the buckle device by inserting it into an insertion opening provided in the buckle device. On the other hand, the tongue can be unlocked by pressing the release button of the buckle device. In addition, hooks may be used to lock each other, hook-and-loop fasteners may be used, and any removable connection mechanism may be used.

Further, the pressure band 33 has an elastic part 332 formed in a part thereof so as to be able to expand and contract in the longitudinal direction. As shown in FIGS. 9 and 10, when pressing the lateral ends of the placed futon F, the pressure band 33 is stretched over the lateral ends, so the thickness of the futon F Accordingly, the pressure 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 expanding the extensible portion 332 by the distance. Furthermore, in the stretchable part 332, a restoring force is always generated due to the connection between the connecting member 331 and the connecting device 313 in the extended state. Can be pressed. It is preferable that such an elastic part 332 is a member having elasticity such as a coil spring or a rubber body, and the entire pressing band 33 may be used as the elastic part 332.

Further, as shown in FIG. 13, the pressure band 33 is uniformly provided with a group of ventilation holes 333 including the elastic portion 332, so that the futon F in contact with the pressure band 33 can be ventilated. In addition, in FIG. 13, the ventilation hole group 333 is formed in circular holes, and a large interval is formed between the holes, but the pressure band 33 is made of a mesh member in which fine holes are formed. It's okay.

(Flow path and operation in dryer)
The flow path in the dryer will be explained using FIGS. 11, 14, and 15. 14 and 15 are a sectional view taken along the line BB and CC in FIG. 11, respectively. For convenience of explanation, in FIG. 11, the connection pipes 253, 254 and a portion of the connection pipe 231, which are disposed at different positions in the left-right direction from the cut surface, are virtually shown by dashed lines. Similarly, in FIG. 14, the connecting pipes 253, 231 located above the cut surface are virtually shown by dashed-dotted lines, and in FIG. is shown. Further, dotted arrows shown in each of these figures indicate the direction of air flow.

As shown in FIG. 11, two flat plate parts 25a and 25b extending horizontally and parallel to each other are provided above the upper wall part 25 of the housing 20. A gas heater 21, an exhaust fan 22, and a mist generator 23 are placed on 25b, respectively. Two spaces are vertically divided and defined by a flat plate part 25a located below the flat plate part 25b, and a space is defined between the flat plate part 25a and the upper wall part 25. The space defined between the flat plate portion 25a and the flat plate portion 25b is used as the upper exhaust flow path 252. The upper exhaust flow path 252 extends slightly rearward than the intake flow path 251 and is fluidly connected to the vertical flow path 271 . Note that 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 formed of a heat insulating member.

The vertical flow path 271 is a gap between the rear wall portion 27 and a flat plate portion 27a located in front and parallel to the rear wall portion 27, and has a rectangular cross section that is elongated in the left and right direction when viewed from above, and is formed in the vertical direction. It is formed as an extending space. 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.

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. The connection pipe 253 is formed corresponding to the gas heater 21 and is fluidly connected to the intake flow path 251 so that air heated by the gas heater 21 can be sucked into the intake flow path 251. The connecting pipe 231 has one end connected to the liquid storage tank of the mist generating section 23 and the other end connected to the connecting pipe 253, so that the mist generated by the mist generating section 23 is sent to the intake flow path through the connecting pipe 253. 251. The connecting pipe 254 is formed to correspond 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, an inflow hole group 255 is formed in the upper wall portion 25 as a vent hole that communicates the intake flow path 251 with the drying space D and allows air heated by the gas heater 21 to flow into the drying space D. This inflow hole group 255 is a plurality of punched holes, and is formed over the entire area of the drying space D in the left-right direction and a predetermined range in the front-back direction. The predetermined range here is approximately the entire lower region of the intake flow path 251, and more specifically, from the upper part of the rear end of the mounting table 31 in the front-rear direction to the front end of the intake flow path 251 in the front-rear direction. range. The effect of the inflow hole group 255 formed in this predetermined range will be described in detail later.

Next, how to use the dryer 1 will be explained. First, the movable placing part 3 is pulled out from the drying space D, and after placing the futon F on its placing surface, the movable placing part 3 is moved a predetermined distance backward in the front-back direction so that the door part 29 can be closed. move it. As a result of this movement, the rear wheel casters 322b and the support casters 285 run on opposing surfaces including the corresponding inclined surfaces, and the opening 321b of the pedestal 32 and the opening 282 of the bottom wall 28 approach each other, causing the sealing member to close. These openings are connected via 288. In this state, the door portion 29 can be closed and the movable placement portion 3 can be completely accommodated in the drying space D. When the movable placement section 3 is completely accommodated in the drying space D, the internal spaces P and T of the movable placement section 3 and the lower exhaust flow path 281 are fluidly connected, and therefore the internal spaces P and T and the upper The exhaust flow path 252 will be fluidly connected.

After the movable placement unit 3 is accommodated in the drying space D, when the user controls the control unit 24 and operates the exhaust fan 22, the air in the upper exhaust flow path 252 is exhausted to the outside. The internal spaces P and T in the movable mounting section 3 become under 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 through the punching hole group 311 provided on both sides of the mounting table 31 and is sucked into the movable mounting section 3. Ru. 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 intake flow path 251 that is communicated with the drying space D by the inflow hole group 255. Inhaled.

If the gas heater 21 is operating while air is flowing into the drying space D, the air heated by the gas heater 21 will flow into the drying space D as hot air, and this hot air will flow into the movable mounting section 3. The futon F is dried by passing through the placed futon F and flowing into the movable placement part 3 and then being discharged to the outside of the dryer 1.

When the fog generation section 23 is operating in a state where air flows into the drying space D, the air containing the mist generated by the fog generation section 23 flows into the drying space through the connection pipe 253 and the intake flow path 251. When the air containing this mist passes through the futon F, chemicals such as deodorants, disinfectants, and anti-mite agents can penetrate into the futon F. Spraying of chemicals can be automated.

(Effects due to a group of inflow holes formed in a predetermined range)
The effects obtained by the inflow hole group formed in a predetermined range on the upper wall of the casing will be explained.

As described above, hot air, which is air heated by the gas heater 21, flows into the drying space D from the inflow hole group 255, so when the inflow hole group 255 is formed closer to the front end side, the hot air is located directly below the inflow hole group 255. Although the futon part becomes hot, for example, the futon part located on the rear end side 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 located above one end of the mounting table 31 in the front and back direction. Compared to the case where only the drying space D is formed, the hot air flowing in from above can be blown down onto the futon F over a wider range, and the temperature distribution within the drying space D can be made more uniform in the front-rear direction. Such equalization of temperature distribution makes it possible to reduce temperature unevenness of the futon F.

As shown in FIGS. 11 and 14, in this embodiment, since the control unit 24 is disposed in front of the intake flow path 251, the intake flow path 251 does not extend above the front end of the mounting table 31. Not yet. Needless to say, even in this configuration, temperature unevenness can be reduced compared to a configuration in which hot air is blown down only from a part. Note that the intake flow path 251 extends above the front end of the mounting table 31, and therefore extends so as to completely cover the upper part of the mounting table 31 (for example, extends below the control unit 24). It is more preferable to do so, and by doing so, it becomes possible to blow down the hot air over the entire area of the mounting table 31 in the front and back direction, and it is possible to further reduce the temperature unevenness of the futon F.

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

In this embodiment, the object to be dried is described as a futon F, but the object is not limited to this, but other mat-like members made of fiber materials such as carpets, rugs, mattresses, etc. can be placed thereon. It may be dried.

Further, although it has been explained that the punching hole group 311 and the inflow hole group 255 are circular holes, they may also be square holes, and the mounting surface and the upper wall portion 25 are formed in a net shape, and the net openings are formed in the shape of a net. It may be made to correspond to the punching hole group 311 or the inflow hole group 255.

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

The embodiments of the invention are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included within the scope and gist of the invention, as well as within the scope of the invention described in the claims and its equivalents.
