The longitudinal position of the partition section 35 is matched to the transverse width of a single-sized futon, and the length of the entire placing section 31 in the longitudinal direction is matched to the transverse width of a double-sized futon. It has become a thing. This makes it possible to dry futons of different sizes, as will be described in detail later. In addition, it is also possible to dry not only futons but also other mat-like members made of fiber materials such as carpets, rugs, and mattresses.

Furthermore, as shown in FIG. 6, punching hole groups 311a and 311b are provided on both side surfaces of the mounting section 31 to communicate the first space P1 and the second space P2 with the outside of the mounting section 31, respectively. These punching hole groups 311a and 311b are provided over a predetermined distance from the uppermost end of the placing portion 31, and this predetermined distance is set to be more than half the longitudinal width of the futon. The punching hole group 311a is provided to cover substantially the entire area of the first space P1 in the front-rear direction, and similarly, the punching hole group 311b is provided to cover substantially the entire area of the second space P2 in the front-rear direction. It is set up like this. In addition, in the following description, when the punching hole groups 311a and 311b are not distinguished, they are simply referred to as the punching hole group 311.

The pedestal portion 32 is formed into a hollow substantially rectangular parallelepiped shape as described above, and connects the vertical flow path 203 (see FIGS. 10 to 12), which will be described later, and the first space P1 (see FIG. 6). A communication hole 329 (see FIGS. 5 and 7) is provided on the back surface of the pedestal portion 32 to communicate the connection channel T1 with the vertical channel 203. A communication hole 318 (see FIG. 5) is provided on the bottom surface of the placement section 31 to communicate the first space P1 with the connection flow path T1, and a communication hole 318 (see FIG. 5) is provided on the back surface of the placement section 31 to communicate the first space P1 with the connection flow path T1. A communication hole 319 (see FIGS. 5 and 7) is provided to communicate with the passageway.

The base portion 32 is provided with a protrusion portion 320 on the bottom surface of which a portion of the front end protrudes downward over substantially the entire area in the left and right direction. The pedestal portion 32 has two front wheel casters 321a, 321b provided on the front side, specifically, on both left and right sides of the protruding portion 320, and two rear wheel casters 322a, 322 provided on both left and right sides on the rear side.

According to the protruding part 260 provided on the bottom part 26, the two rear wheel casters 322a and 322b are restricted from being placed in front of the protruding part 260, so that the user cannot move the movable mounting part 3 forward. When this is done, the entire movable mounting section 3 is prevented from coming out of the drying space D.

(Flow path in dryer)
The flow path in the dryer will be explained. 10 and 11 are a sectional view taken along the line AA' and BB' of FIG. 2, respectively. FIG. 12 is a plan view showing the dryer with a part of the structure shown. Note that FIG. 12 shows a dryer in which a gas heater, an exhaust fan, and a mist generating section are transmitted.

As shown in FIGS. 10 to 12, the housing 20 includes a flat plate part on which a gas heater 21, an exhaust fan 22, and a mist generating part 23 are placed, and a drying space D parallel to the flat plate part. A horizontal space different from the drying space D is defined between the drying space D and the flat plate part provided so as to be closed from above. Furthermore, this horizontal space is divided into two spaces, which are used as an exhaust flow path 201 and an intake flow path 202.

In addition, inside the drying space D, there is a vertical line that extends in the vertical direction, that is, in the vertical direction, along the back surface of the drying space D, and is communicated with the exhaust flow path 201 so as to substantially form a part of the exhaust flow path 201. A flow path 203 is formed. This vertical flow path 203 is a gap between a flat plate part forming the back surface of the casing 20 and a flat plate part parallel to this flat plate part, and has a rectangular cross section that is long in the left and right direction when viewed from above and extends in the vertical direction. It is formed as a space that exists.

The vertical flow path 203 is formed so as to communicate with the exhaust flow path 201 at its upper end, but not with the intake flow path 202 . In addition, the vertical channel 203 includes a communication hole 203a that communicates the vertical channel 203 with the connecting channel T1 formed in the pedestal section 32 of the movable mounting section 3, and a communication hole 203a that communicates with the vertical channel 203. A communication hole 203b is formed that communicates the second space P2 formed in the vertical flow path 203 with the second space P2.

When the movable mounting section 3 is completely accommodated in the drying space D so that the door section 29 can be closed, a communication hole 329 formed on the back surface of the pedestal section 32 and a vertical flow path 203 are formed. The communication holes 203a formed in the vertical and horizontal directions are close to each other so that at least a portion thereof overlaps, and the communication holes 319 formed on the back surface of the mounting section 31 and the communication holes 203b formed in the vertical flow path 203 are arranged vertically. They are adjacent to each other so that at least a portion thereof overlaps in the left-right direction. As a result, as shown in FIG. 10, each of the connection channel T1 and the second space P2 communicates with the vertical channel 203.

As shown in FIG. 12, communicating holes 21a, 22a, and 231a are formed in the flat plate portion of the housing 20 on which the gas heater 21, exhaust fan 22, and mist generating section 23 are placed. The communication hole 21 a is formed corresponding to the gas heater 21 and is formed to be able to draw air heated by the gas heater 21 into the intake flow path 202 . The communication hole 22a is formed corresponding to the exhaust fan 22, and is formed so that the exhaust fan 22 can take in air from the exhaust flow path 201. The communication hole 231a is formed corresponding to the connection pipe 231, and one end of the connection pipe 231 is connected to the liquid storage tank of the mist generation section 23, and the other end is connected to the intake flow path 202 through the communication hole 231a. fluidly connected to.

The intake flow path 202 is formed with an inflow hole group 202a that communicates the intake flow path 202 with the drying space D and allows air heated by the gas heater 21 to flow into the drying space. The inflow hole group 202a is a plurality of punched holes formed in a flat plate portion provided so as to close the drying space D from above and the horizontal space from below. It is formed over substantially the entire area of the space D in the left and right direction. This makes it possible to reduce variations in temperature within the drying space D, for example, compared to the case where the punched holes are formed closer to one side in the left-right direction.

Note that a plurality of inflow hole groups 202a may be formed at different positions in the front-rear direction. Furthermore, when a plurality of inflow hole groups 202a are formed, it is desirable that the aperture ratio of the inflow hole groups 202a and the region in which the punched holes are formed be larger on the front side than on the rear side. This makes it possible to reduce the amount of hot air blown out on the side closer to the air source, that is, the vertical flow path 203, and to make the temperature distribution in the drying space D more uniform in the front-rear direction.

In the dryer 1, when the exhaust fan 22 is operated, the space inside the movable mounting section 3 becomes negative pressure through the exhaust flow path 201 and the vertical flow path 203, and the pressure inside the movable mounting section 3 becomes negative. Air in the drying space D is sucked into the movable mounting section 3 through the punched hole groups 311a and 311b. As a result, the inside of the drying space D becomes negative pressure, and the air outside the dryer 1 passing through the gas heater 21 is sucked into the drying space D through the intake flow path 202 that is communicated with the drying space D by the inflow hole group 202a. be done.

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 unit 23 is operating in a state where air is flowing into the drying space D, air containing the fog generated by the fog generation unit 23 flows into the drying space D via the intake flow path 202. By allowing this mist-laden air to pass through the futon F, it is possible for chemicals such as deodorants, disinfectants, and anti-mite agents to penetrate into the interior of the futon F, as well as to prevent the dispersion of chemicals. Can be automated.

In addition, by using an ultrasonic atomizer as the mist generation unit 23, it is possible to generate a finer mist, whereby the atomized medicine adheres to the surface of the futon F in the form of water droplets. This can be prevented, and the drug can be more efficiently permeated into the futon F. Furthermore, the spraying of chemicals by the mist generation unit 23 can also be applied to drying clothes and the like.

(Effect by suppressor)
The effect obtained by the suppressing part provided on the movable mounting part will be explained.

As described above, the futon F is dried by passing the futon F when the hot air in the drying space D flows into the space in the movable placement part 3 through the punching hole group 311. That is, when drying the futon F, it is desirable to place the futon F on the placement part 31 so that the futon F closes the punched hole group 311 into which hot air flows.

When the punching hole group 311 is blocked by the futon F, the front and back ends of the placed futon F rise due to the bulge or distortion of the ends of the futon F, that is, become separated from the side surface of the placement part 31. There is a tendency for gaps to form. In this case, at the front and rear ends of the futon F, the hot air in the drying space D does not pass through the futon F but flows into the space inside the movable placement part 3 from a part of the punching hole group 311. , the drying rate of the futon F will decrease.

According to the suppressing part 33, as shown in FIGS. 8 and 9, the protruding part 331 guides the front end of the futon F so that it does not separate from the side surface of the placing part 31, thereby reducing the drying rate. can be reduced. Here, the protruding portion 331 is formed such that the distance from the side surface of the placing portion 31 is equal to or less than the average thickness of the futon F. Further, the suppressing part 33 may be provided at the rear end of the placing part 31, and the suppressing part 33 allows the user to adjust the distance between the protruding part 331 and the placing part 31 according to the thickness of the futon F. 33 may be configured. Moreover, the suppressing part 33 may be provided only on one of the two side surfaces of the mounting part 31 divided by the bending line. Further, the suppressing part 33 is formed to be able to be stored in the placing part 31 or to be foldable outward in the front and back direction of the placing part 31, so that the suppressing part 33 does not interfere with placing or collecting the futon F. 33 may be configured. Further, the entire suppressing portion 33 may be made of a member having air permeability, such as a punching plate, so that the flow of hot air within the futon F is not obstructed.

Further, the suppressing part 33 may be any member as long as it can prevent the front and rear ends of the futon F from separating from the side edges of the placing part 31. It is also possible to use a band-shaped member in which the two ends are connected, or a band-shaped member in which both ends are connected at different positions in the vertical direction at the front-rear end of the mounting portion 31. Furthermore, one end of the suppressing part 33 is connected to the front end of the placing part 31, and the other end can be connected to either the side surface of the placing part 31 where the partition part 35 is formed or the rear end of the placing part 31. By forming the belt-like member as a belt-like member, it is possible to prevent futons F from separating when the futons F are of different sizes.

(Configuration and operation of flow path switching section)
The configuration and operation of the flow path switching section will be explained.

As shown in FIG. 4 and FIG. 10 to FIG. It has a shaft 243 to which one end is connected, and a closing part 242 to which the other end of the shaft 243 is connected.

The drive unit 241 is a motor installed on the mounting base 240 with the rotational axis direction oriented in the left-right direction, and the drive unit 241 and the shaft 243 are connected to a conversion mechanism 244 (see FIG. 10) that converts rotational motion into linear motion. connected via. The shaft 243 is supported by the mounting base 240 so as to be movable in the front-back direction. The closing portion 242 is formed to be able to close the communication hole 203b provided in the vertical channel 203 from the rear.

The flow path switching unit 24 can be switched between a closed state in which the communication hole 203b is closed and an open state in which the communication hole 203b is opened by moving the shaft 243 back and forth using the drive unit 241. In addition, the flow path switching unit 24 can be switched between a closed state and an open state to create a first flow path in which air passes only through the first space P1 and is discharged to the outside of the dryer 1; It is possible to switch to a second flow path that passes through the space P1 and the second space P2 and is discharged to the outside of the dryer 1.

By operating the operation panel 251, the user switches to the first flow path when the single-sized futon F is placed on the movable placement section 3 so as to overlap the front and rear width of the first space P1. , when the double-sized futon F is placed on the movable placement part 3 so as to overlap not only the first space P1 but also at least a part of the front-to-back width of the second space P2, the flow path is switched to the second flow path. be able to. Thereby, the flow path through which air passes through the space within the movable placement section 3 can be made in accordance with the size of the futon F.

Furthermore, according to the flow path switching section 24 provided in the housing 20, compared to the case where a mechanism for switching the flow path when passing through the space inside the movable mounting section 3 is provided on the movable mounting section 3 side. , the drying space D can be used more effectively, and electric power can be easily secured because it is easier to secure a power source. Note that the flow path switching unit 24 may be provided in the housing 20 and configured to be able to open and close either one of the communication holes 203a and 203b.

(Configuration and operation of control unit)
The configuration and operation of the control section will be explained. FIG. 13 is a block diagram showing the configuration of the control section. FIG. 14 is a flowchart showing the operation of the control section.

As shown in FIG. 13, in addition to the operation panel 251, the control unit 25 further includes a CPU (Central Processing Unit) 252, a RAM (Random Access Memory) 253, a storage device 254, and an input/output IF (Interface) 255.

The CPU 252 cooperates with the RAM 253 to execute operations described below. The storage device 254 stores data related to the execution of operations described below. The input/output IF 255 is an interface for connecting the operation panel 251 as an input/output device.

The operation panel 251 includes a ventilation button for instructing the ventilation operation described later, a size button for setting the size of the futon to be dried, a scattering button for setting whether to perform the spraying operation described later, and these buttons. It shall be equipped with a lamp or a 7-segment display that indicates the instruction status of the button. Further, the control unit 25 is provided with a payment machine (not shown), and the control unit 25 operates the dryer 1 by inserting a predetermined coin, and performs one ventilation operation prior to operation. It shall be set as possible.

As shown in FIG. 14, the control unit 25 first determines whether the remaining number of ventilation operations is one or more (S101).

If the remaining number of times is one or more (S101, YES), the control unit 25 determines whether or not the ventilation button has been pressed on the operation panel 251 (S102).

When the ventilation button is pressed (S102, YES), the control unit 25 causes the dryer 1 to perform a ventilation operation (S103). Here, according to the ventilation operation, only the exhaust fan 22 is operated for a predetermined time, for example, about 15 seconds, in order to reduce the odor remaining in the drying space D due to the previous drying of the futon F, especially the spraying of chemicals. . Further, the remaining number of times is reduced by 1 along with the ventilation operation.

Next, the control unit 25 determines whether a coin has been inserted into the payment machine as a trigger for starting operation (S104).

When a coin is inserted into the payment machine (S104, YES), the control unit 25 determines whether a single size is selected as the size of the futon F to be dried using the size button (S105).

If the single size is selected (S105, YES), the control unit 25 causes the dryer 1 to perform the first drying operation (S106). Here, according to the first drying operation, the gas heater 21 and the exhaust fan 22 are operated after the flow path switching section 24 is switched to the closed state.

Next, the control unit 25 determines whether settings have been made to perform a spraying operation (S107).

If the setting is made to perform the spraying operation (S107, YES), the control unit 25 causes the dryer 1 to perform the spraying operation (S108). Here, according to the spraying operation, the exhaust fan 22 and the mist generating section 23 are operated. Next, the control unit 25 resets the remaining number of times and sets it to 1 (S109).

On the other hand, if the setting to perform the spraying operation is not made (S107, NO), the control unit 25 causes the dryer 1 to perform a cooling operation in which only the exhaust fan 22 is operated (S110), resets the remaining number of times, and (S109).

Further, in step S105, if the single size is not selected, that is, if the double size is selected (S105, NO), the control unit 25 causes the dryer 1 to perform the second drying operation (S111). . Here, according to the second drying operation, the gas heater 21 and the exhaust fan 22 are operated after the flow path switching section 24 is switched to the open state.

Further, in step S104, if no coin is inserted into the payment machine (S104, NO), the control unit 25 determines again whether the remaining number of ventilation operations is 1 or more (S101).

Further, in step S102, if the ventilation button is not pressed (S102, NO), the control unit 25 determines whether a coin has been inserted into the payment machine (S104).

Further, in step S101, when the remaining number of ventilation operations is less than 1, that is, 0 (S101, NO), the control unit 25 determines whether a coin has been inserted into the payment machine (S104).

In this way, after the drying operation, by causing the dryer 1 to perform a spraying operation in which the gas heater 21 is not operated and only the exhaust fan 22 and the mist generation unit 23 are operated, the atomized chemical is chemically changed by heat. can be prevented from occurring. Note that in this embodiment, the spraying operation also serves as the above-mentioned cooling operation, but it may be performed separately after the cooling operation.

In addition, prior to the drying operation, by making it possible to perform a ventilation operation in which only the exhaust fan 22 is operated according to the operation of the user, drying caused by drying the futon F last time or spraying chemicals on the futon F can be avoided. It is possible to reduce the adhesion of the odor in the space D to the futon F of the user.
