(Flow path in dryer)
A flow path in the dryer will be described. 10 and 11 are sectional views taken along line AA' and line BB' of FIG. 2, respectively. FIG. 12 is a top plan view of the dryer with some components shown in transparency. In addition, FIG. 12 shows a gas heater, an exhaust fan, and a dryer through which the mist generating section is transmitted.

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

Further, in the drying space D, along the rear surface of the drying space D, a vertical wall extending in the vertical direction, that is, in the vertical direction, is communicated with the exhaust flow path 201 to substantially form a part of the exhaust flow path 201 . A channel 203 is formed. The vertical flow path 203 is a gap between the flat plate portion forming the back surface of the housing 20 and the flat plate portion parallel to the flat plate portion, and has a rectangular cross section that is elongated in the horizontal direction when viewed from above and extends in the vertical direction. It is formed as a space that exists.

The vertical channel 203 is formed so that its upper end communicates with the exhaust channel 201 and does not communicate with the intake channel 202 . Further, in the vertical flow path 203, a communication hole 203a for communicating the vertical flow path 203 with the connecting flow path T1 formed in the pedestal portion 32 of the movable mounting section 3, and the mounting section 31 of the movable mounting section 3 A communication hole 203b is formed to communicate the second space P2 formed in the second space P2 and the vertical flow path 203. As shown in FIG.

When the movable mounting portion 3 is completely accommodated in the drying space D so that the door portion 29 can be closed, the communication hole 329 formed in the back surface of the base portion 32 and the vertical flow path 203 are formed. The communication hole 203a is close to the communication hole 203a so that at least a part of it overlaps in the vertical and horizontal directions, and the communication hole 319 formed in the back surface of the mounting section 31 and the communication hole 203b formed in the vertical flow path 203 are vertically aligned. They are close to each other so that at least a part of them 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 and the vertical channel 203 are communicated with each other.

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

In the air intake passage 202, an inlet hole group 202a is formed to allow the air intake passage 202 and the drying space D to communicate with each other and allow the 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 so as to close the drying space D from above and to close the horizontal space from below. It is formed over substantially the entire area of the space D in the left-right direction. As a result, the variation in temperature in the drying space D can be reduced, for example, as compared with the case where the punched holes are formed so as to be close to one side in the left-right direction.

In addition, the inflow hole group 202a may be formed in multiple positions at different positions in the front-rear direction. Further, when forming a plurality of inflow hole groups 202a, it is desirable that the opening ratio of the inflow hole groups 202a and the region where the punching holes are formed are larger on the front side than on the rear side. As a result, the blowing amount of the hot air at the blow source, that is, the side closer to the vertical flow path 203 can be reduced, and the temperature distribution in the drying space D can be made 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 via the exhaust flow path 201 and the vertical flow path 203, and The air in the drying space D is sucked into the movable mounting portion 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 drawn into the drying space D through the intake passage 202 communicating with the drying space D through the inflow hole group 202a. be done.

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, air containing fog generated by the fog generating section 23 flows into the drying space D through the air intake passage 202. As a result, the mist-containing air passes through the futon F, allowing chemicals such as deodorants, sterilizers, and anti-mite agents to permeate the interior of the futon F, and the chemicals can be sprayed. Can be automated.

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

(Effect of suppression part)
The effect obtained by the suppressing portion provided on the movable placing portion will be described.

As described above, the hot air in the drying space D dries the bedding F by passing through the bedding F when flowing into the space in the movable placement section 3 through the punching hole group 311 . That is, when drying the bedding F, it is desirable to place the bedding F on the placing portion 31 so that the bedding F closes the punching hole group 311 into which the hot air flows.

When the punched hole group 311 is blocked by the blanket F, the front-rear end portions of the placed blanket F are lifted due to the swelling or distortion of the edge portions of the blanket F, that is, separated from the side surface of the placing portion 31. gaps tend to occur. In this case, at the front and rear ends of the blanket F, the hot air in the drying space D does not pass through the blanket F, but flows into the space inside the movable placement section 3 through part of the punching hole group 311. , the drying rate of the futon F is lowered.

According to the suppressing portion 33, as shown in FIGS. 8 and 9, the projection portion 331 guides the front end portion of the futon F so as not to separate from the side surface of the placing portion 31, thereby preventing the drying rate from being lowered. can be reduced. Here, the projecting portion 331 is formed so 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. As shown in FIG. Further, the suppressing portion 33 may be provided at the rear end portion of the placing portion 31, and the user can adjust the distance between the projecting portion 331 and the placing portion 31 according to the thickness of the futon F. 33 may be configured. Moreover, the suppressing portion 33 may be provided on only one of the two side surfaces of the placing portion 31 divided by the folding line.

In addition, the suppressing portion 33 may be any device as long as it can prevent the front and rear ends of the futon F from being separated from the side edges of the placing portion 31 . or a belt-like member having both ends connected to different positions in the vertical direction at the front-rear direction ends of the mounting portion 31 .

(Configuration and operation of flow path switching unit)
The configuration and operation of the channel switching unit will be described.

As shown in FIGS. 4 and 10 to 12, the flow path switching unit 24 includes a mounting base 240 fixed to the rear side of the housing 20, a driving unit 241 provided on the mounting base 240, and a driving unit 241. 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 provided on the mounting base 240 with the direction of the rotation axis oriented in the horizontal direction. The drive unit 241 and the shaft 243 form a conversion mechanism 244 (see FIG. 10) that converts rotary motion into linear motion. connected via The shaft 243 is supported by the mounting base 240 so as to be movable in the front-rear direction. The closing part 242 is formed so as to be able to close the communication hole 203b provided in the vertical channel 203 from behind.

By moving the shaft 243 back and forth with the drive unit 241, the channel switching unit 24 can switch between a closed state in which the communication hole 203b is closed and an open state in which the communication hole 203b is opened. In addition, the flow path switching unit 24 switches between the closed state and the open state so that the first flow path in which the air passes only through the first space P1 and is discharged to the outside of the dryer 1 and the first flow path in which the air passes through the first space P1 are discharged. It can be switched 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 .

The user operates the operation panel 251 to switch to the first flow path when the single-size futon F is placed on the movable placement unit 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 unit 3 so as to overlap not only the first space P1 but also at least a part of the front-to-rear width of the second space P2, the flow path is switched to the second flow path. be able to. As a result, the flow path for the air to pass through the space in the movable placement section 3 can be adapted to the size of the futon F. FIG.

In addition, according to the flow path switching unit 24 provided in the housing 20, compared with the case where the mechanism for switching the flow path when passing through the space in the movable mounting unit 3 is provided on the movable mounting unit 3 side , the drying space D can be used more effectively, and since it is easier to secure a power supply, motorization is also easy. It should be noted that the channel switching unit 24 may be provided in the housing 20 and configured to be able to open or close either one of the communication holes 203a and 203b.

(Configuration and operation of control unit)
The configuration and operation of the control unit will be described. FIG. 13 is a block diagram showing the configuration of the control unit. FIG. 14 is a flow chart showing the operation of the control unit.

As shown in FIG. 13 , in addition to an operation panel 251 , the control section 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 perform operations described later. The storage device 254 stores data relating to execution of operations described later. 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 a ventilation operation, which will be described later, a size button for setting the size of the futon to be dried, a scatter button for setting whether to perform a scatter operation, which will be described later, and these buttons. It shall be equipped with a lamp or a 7-segment display to indicate the indication status of the button. In addition, 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. shall be enabled.

As shown in FIG. 14, the control unit 25 first determines whether or not the remaining number of ventilation operations is one or more (S101).

When 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).

If the ventilation button has been pressed (S102, YES), the controller 25 causes the dryer 1 to perform the 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. . In addition, the remaining number of times is reduced by one with the ventilation operation.

Next, the control unit 25 determines whether or not a coin has been inserted into the payment machine as a trigger for starting operation (S104).

When coins have been inserted into the payment machine (S104, YES), the control unit 25 determines whether or not the single size has been selected as the size of the futon F to be dried by the size button (S105).

If the single size is selected (S105, YES), the controller 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 switching the flow path switching section 24 to the closed state.

Next, the control unit 25 determines whether or not the setting to perform the spraying operation is made (S107).

When the setting to perform the spraying operation is made (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 fog generator 23 are operated. Next, the control unit 25 resets the remaining number of times to 1 (S109).

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

If the single size is not selected in step S105, that is, if the double size is selected (S105, NO), the controller 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 switching the flow path switching section 24 to the open state.

Further, in step S104, when no coin is inserted into the payment machine (S104, NO), the control unit 25 again determines whether or not the remaining number of ventilation operations is 1 or more (S101).

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

In step S101, when the number of remaining ventilation operations is less than 1, ie, 0 (S101, NO), the control unit 25 determines whether or not a coin has been inserted into the payment machine (S104).

In this way, after the drying operation, the dryer 1 is caused to perform the spraying operation in which only the exhaust fan 22 and the mist generating section 23 are operated without operating the gas heater 21, so that the atomized medicine is chemically changed by heat. can be prevented from occurring. In this embodiment, the spraying operation is assumed to serve as the cooling operation described above, but may be performed separately after the cooling operation.

In addition, prior to the drying operation, the ventilation operation of operating only the exhaust fan 22 can be executed according to the operation of the user, so that the drying caused by the previous drying of the bedding F or the spraying of chemicals on the bedding F Adherence of the odor in the space D to the futon F of the user can be reduced.

As shown in FIG. 15, in the dryer 1a according to the modification, a part of the wall section that separates the exhaust flow path 201 and the intake flow path 202 is configured as a movable wall section 209, and the movable wall section 209 is rotated. It further includes a channel reversal driving unit 209a for moving and an auxiliary gas heater 27 provided so as to communicate with the vertical channel 203. As shown in FIG. The flow path reversal driving section 209a rotates the movable wall section 209 around an axis directed in the vertical direction, thereby reversing the flow of air in the dryer 1a.

The movable wall portion 209 is rotationally moved by the channel reversing portion 209 a so as to suck the air in the drying space D through the intake channel 202 instead of the exhaust channel 201 . At this time, as shown in FIG. 16, the flow direction of the air is reversed, and the air heated by the auxiliary gas heater 27 flows from the movable placement section 3 through the bedding F and into the drying space D. Become.

In this way, by allowing hot air to pass through the futon F from inside the movable placement portion 3, the density of members such as batting stuffed in the futon F can be reduced and the members can be expanded. To improve the state in which the batting in the futon F is compressed by allowing hot air to pass through the futon F from outside the movable placing part 3 into the futon F when drying the futon F, and reversing the flow direction of the air after drying. can be done.

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.
