DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drying apparatus which is installed in a coin laundry or the like and which can dry articles to be dried such as clothes, futons and blankets by inserting a predetermined amount of currency, and more particularly to futons and the like. The present invention relates to a drying apparatus suitable for drying a large object to be dried.

[0002]

2. Description of the Related Art As a conventional apparatus for drying futons, as proposed by the present applicant in Japanese Patent Application Laid-Open No. 2-239894, a drum is provided in a laterally lying state in an outer shell, and a hinge is provided on a front surface of the outer shell. Provide a door that opens and closes, open this door and put futons into the drum, rotate the drum by centrifugal force so that the futons stick to the inner surface of the drum, and supply steam to the outer shell in this state There are devices that steam futons and then dry the futons by supplying hot air into the outer shell while rotating the drum.

[0003]

However, since the conventional drying apparatus is a door which opens and closes by turning laterally about a hinge, the door is used when a large object to be dried such as a futon is taken in and out. Inconveniences, such as the door being in the way or the open door hitting other objects. In particular, coin laundries, etc., tend to have as little space as possible in front of the drying device because they install as many washing and drying devices as possible in a limited space to increase space efficiency. In addition, when the door is pulled forward and opened, the user is forced to use an unreasonable posture, and the usability is insufficient.

Further, even if the door is simply slid, it cannot be put to practical use. That is, in order to make the door slide, the door is moved up and down along the slide rail. However, the inlet cannot be sealed unless the descending door is advanced, so the lower part of the slide rail is placed on the inlet side. It is necessary to bend. However, when the door is gradually advanced while being lowered, the packing material on the back surface of the door moves obliquely downward with respect to the front surface of the device when the door comes into contact with the input port. While being crushed. Also, when the door is opened, the packing material gradually moves away while sliding with respect to the front surface of the apparatus. Therefore, if the door is slid only by using the curved slide rail, the packing material is greatly worn when the door is repeatedly opened and closed, which causes a problem in durability.

[0005] Further, since anyone can enter and exit the coin laundry freely, if the door is left open,
It is also conceivable that a child or an inexperienced person puts foreign matter into the drum by mischief, which is not preferable in terms of management.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a drying apparatus which does not obstruct a door when an object to be dried is taken in and out, and which can prevent foreign substances from being introduced into a drum. .

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a reproducing apparatus 1 such as a futon which is a typical drying apparatus, FIG. 2 is a front view of a state in which a door 2 is opened, FIG. 3 is a cross-sectional view of the reproducing apparatus 1 cut in the front-back direction, and FIG. FIG. 2 is a cross-sectional view of the device cut in the width direction.

In the regenerating apparatus 1, a drum 4 is rotatably provided in a substantially rectangular parallelepiped housing 3 which can be hermetically sealed in a horizontal state, and a steam jetting tank 5 is provided with the outer peripheral surface of the drum 4 facing from below. It is provided.

The housing 3 has a front surface serving as a material-to-be-dried charging section.
A circular inlet 6 having a diameter slightly smaller than the inner diameter of the drum 4 is opened, and a door 2 for opening and closing the inlet 6 is provided. The door 2 in the present embodiment is a substantially square, a sliding door that is provided with a round window 7 at the center and moves vertically along the front surface of the housing via left and right support members 9.
For this purpose, as shown in FIG. 5, slide rails 10 and 10 are provided vertically on the left and right sides of the front surface of the housing 3, and a slide rail bracket 11 is attached to a slider 10 'that moves along each slide rail 10. The support member 9 is attached to the rail bracket 11 with an auxiliary member 11 ′ in such a manner that the support member 9 can be moved back and forth by a bolt 12, and the door 2 is attached to the bolt 12 on the near side (in a direction away from the front surface of the housing). The energizing coil spring 13 is fitted, and the door closing air cylinder 15 is fixed to a bracket 14 extending from the housing 3 side as a closing drive source.

A steam supply pipe 36 is connected to the lower surface plate 30b constituting the steam chamber 35 so as to communicate with the steam chamber 35, and a baffle 37 having a U-shaped cross section is welded to the steam chamber 35 side of the connection port. Fix by, for example.

With this configuration, the steam supplied from the steam supply pipe 36 at the connection port does not directly hit the top plate 30a or the steam outlets 31.
, And steam is jetted almost uniformly from any of the steam jet ports 31. In addition, a packing material 40 is provided on the upper portion of the steam ejection pot 5 so as to surround the group of the steam ejection ports 31 so that the steam ejected from the steam ejection ports 31 is directly supplied into the drum 4. In the present embodiment, the steam ejection pot 5

The air intake port of the blower 50 is connected to the exhaust port 53 which is opened on the upper surface of the blower 50.

Therefore, when the blower 50 is operated, a negative pressure is generated on the intake port side (the intake side ventilation path 51), and the air in the processing chamber 44 provided with the drum 4 is discharged to the exhaust port 55 on the stepped ceiling. The air is sucked out of the suction port, flows into the intake-side ventilation path 51, and is filtered (removal of lint and cotton lint) by a lint filter 52 on the way.
The air is exhausted to the outside through the exhaust port 53 through the duct. Further, when the air in the processing chamber 44 is exhausted in this way, the high-temperature (approximately 140 ° C.) hot air that has passed through the heater 34 and is heated passes through the inlet 56 and the steam pot receiving member 32.
Is sucked into the processing chamber 44 through the hot air supply port 30 of the steam jetting tank 5. If a valve (not shown) provided in the middle of this path is closed, the inside of the processing chamber 44 of the hot air is closed. Supply is stopped.

The futon recycling apparatus 1 according to the present embodiment is a coin-loading dryer that is installed in a coin laundry or the like and used by a user inserting coins (currencies such as coins and bills). Therefore, as shown in FIG. 2, a coin insertion slot 61 is provided as a currency insertion slot on the front surface of a control box 60 provided on the right side surface of the housing 3, and a coin checking slot 70 is provided behind the coin insertion slot 61. It is provided in communication with 61. Note that a bill insertion slot may be provided so that bills such as 1,000-yen bills can be used.

The above-mentioned money checking device 70 includes a control box 60.
It is connected to an electric control device 71 in the inside, and is configured not to start until the inserted coin is proper and reaches a predetermined amount.

As shown in FIG. 9, the electric control device 71 includes a door opening / closing control unit 72, a process control unit 73, and the like. The input / output side of the door opening / closing control section 72 is connected to the checker 70 and the start switches 62R and 62L, and the output side is a solenoid as a valve for controlling the supply of compressed air to the door closing air cylinder 15. Valve (SO
L) 74 and a solenoid valve (SOL) 75 as a valve for controlling the supply of compressed air to the lifting / lowering air cylinder 16
Is connected. On the input side of the process control unit 73, a mode changeover switch 63, an emergency stop switch 64, and a timer 76 provided on the front surface of the control box 60, and on the output side, a process indicator 65 provided on the front surface of the housing 3. A motor 27 for rotating the drum, a motor 50 'for the blower 50, a steam opening / closing valve 77 provided in the middle of the steam supply pipe 36, and a solenoid valve 78 as a valve for the air cylinder 33 for elevating and lowering the steam kettle receiving member are connected. I have.

The door opening / closing control section 72 activates the start switch 62 on condition that the payment end signal is received from the checkout device 70, and on condition that the start signal is received from the start switch 62. The solenoid (SOL) of the lifting / lowering air cylinder and the solenoid 75 of the door closing air cylinder 16 are operated to convert the door 2 from the second state to the first state.

The process control section 73 sets the motor 5 of the blower 50 in accordance with the mode selected by the mode changeover switch 63 based on the procedure of each process which is set in advance.
0 ', the drum rotation motor 27, and the steam on-off valve 77 are controlled, and each process is displayed on the process display 65 to notify the user.

The electric control device 71 may be a sequencer constituted by a logic circuit, or may be a CPU, a RO, or the like.
A microcomputer composed of M, RAM and the like may be used. In short, opening and closing the door 2 according to a preset procedure,
It suffices if the operation of the present apparatus such as the rotation of the drum 4, the supply of hot air, and the supply of steam can be controlled.

Next, the operation of the futon reproducing apparatus 1 provided with the electric control device 71 having the above configuration will be described. First, when the power of the reproducing apparatus 1 is turned on, the electric control device 71 operates the solenoid valve (open / close valve) 75 of the lifting / lowering air cylinder 16 to raise the door 2 and open the input port 6. In this state, it waits for a user operation.

The user puts the futon A into the drum 4 through the open slot 6, and operates the mode changeover switch 63 to select a mode corresponding to the futon A inserted, that is, a mode according to the material. I do. Next, when the coin inserted into the coin insertion slot 61 reaches a predetermined amount, the checker 70
The door opening / closing control section 72, which has received the predetermined amount payment end signal from, confirms the payment of the predetermined amount and activates the start switch 62 based on this. Note that the checkout device 70
, The controller 71 may determine that the payment amount has reached the predetermined amount in the control device 71, that is, determine that the payment has been completed.

When the user operates the start switch 62 in this state,
Is turned on, the door opening / closing control section 72 of the electric control device 71 operates the opening / closing valve (solenoid valve) 75 of the lifting / lowering air cylinder 16 to lower the door 2, and when the door 2 is lowered to a predetermined position, the door closing air is released. The door 2 is advanced by operating the on-off valve (solenoid valve) 74 of the cylinder 15, thereby closing the inlet 6.

The door closing air cylinder 15 keeps pressing the door 2 until the restoring step described later is completed, and the closing state of the inlet 6 is maintained. The start switch 62 may be provided only one at the front of the control box 60. Alternatively, for example, as shown by a dotted line in FIG. 2, the start switch 62 may be provided at a position separated by an interval that cannot be operated with one hand. Two start switches 62R, 6
The start signal may be transmitted when the 2L is operated by each hand, and the start may not be started only by operating one of the start switches.

When such a preparation process is completed, the process proceeds to the next steam process under the control of the process control unit 73.
That is, the process control unit 73 controls each process by transmitting and receiving signals to and from the door opening / closing control unit 72. Then, the process display 65 displays which process is based on a signal from the process control unit 73.

In the steam process, first, the electric control device 7
The first process control unit 73 activates the opening / closing valve (SOL) 78 of the steam ejector air cylinder 33 to raise the steam ejector 5 so as to contact the lower surface of the drum 4 and to control the motor 50 ′ of the blower 50 by steam. Start in the process mode and start housing 3
Start venting the air inside. In this steam process, the drum 4 remains stopped.

Next, the steam on-off valve 7 of the steam supply pipe 36
7 is opened, and high-temperature and high-pressure steam (about 140 ° C., 5 kg / cm 2 to 7 kg / cm 2) is emitted from each steam jet port 31 of the steam jet pot 5.
Squirt. The jetted steam is supplied to the inside of the drum 4 through the ventilation holes 24 of the drum 4 without escaping, since the surroundings of the steam jet port group are sealed with the packing material 40, and the steam flows down the futon A. Pass from side to top. By passing the steam through the futon A, the high heat of the steam can sterilize or kill mites, and the dirt not only on the surface of the futon A but also inside is separated and removed by the flow of the jetted steam. , Cotton and the like can be purified.

Further, in the present embodiment, a concave chamber is provided in the ceiling portion of the housing 3 and a germicidal lamp 66 is mounted in the concave chamber. During operation, the futon A is sterilized by ultraviolet light while being continuously lit.

During the steaming process, the blower 50 is operated to exhaust the inside of the housing 3 as well as the inside of the drum 4, so that the steam ejected from the steam outlets 31 cools and becomes a drain and becomes futon. Wetting of class A can be prevented. The amount of forced exhaust by the blower 50 during the steam process is set to be smaller (the number of rotations of the fan of the blower 50 is set smaller) than the amount of forced exhaust in the drying process and the restoring process described later. The inside is filled with an appropriate amount of steam, so that the futons A can be appropriately steamed. Further, since the filter 52 is provided in the middle of the exhaust path, dirt, cotton dust, and the like coming out of the futon A are filtered by the filter 52 and do not remain in the exhaust gas discharged to the outside through the exhaust port 55.

Such a steam process is performed by a process control unit 73
Is terminated when a predetermined time set in advance by a timer 76 connected to the timer has elapsed. That is, when the predetermined time has elapsed, the steam opening / closing valve 77 of the steam supply pipe 36 is closed to stop the ejection of steam, and the SOL 78 of the air cylinder 33 for the steam pot receiving member is operated to operate the steam ejection pot 5.
To return to a state where the upper surface is separated from the outer peripheral surface of the drum 4. The above-mentioned predetermined time is about 1 minute for a general futon.

When the steam process is completed, the process proceeds to the next drying process under the control of the process controller 73. In the drying step, the heater 34 is operated and the forced exhaust of the blower 50 is operated higher than in the steam step. Also, the drum rotation motor 27 is started to rotate the drum 4. The rotation speed of the drum 4 is determined by the centrifugal force (1.5 to 2.2).
G), the futon A is set to a value that is attached to the inner surface of the drum 4 and rotates together with the drum 4. In the present embodiment, the value is set to 52.5 revolutions per minute (1.68 G).

When the blower 50 is operated while rotating the drum 4 at the above-described rotation speed, the hot air generated by the heater 34 passes through the flow path in the steam pot receiving member 32 and the steam
Is supplied into the housing 3 from the hot air supply port 30. In this drying step, since the state where the steam ejection pot 5 is lowered is maintained, there is a sufficient gap between the upper surface of the steam ejection pot 5 and the outer peripheral surface of the drum 4. 3
From 0, hot air is introduced into the housing 3 without any trouble and the ventilation holes 2
4 enter the drum 4, and the hot air evaporates the moisture of the futon A to dry the futon A. In addition, the evaporated water is discharged outdoors by forced exhaust by the blower 50.

While the drum 4 may be rotated continuously during the drying process, it is desirable to change the position of the futon A with respect to the drum 4 by intermittently rotating. That is, when the rotation of the drum 4 is instantaneously stopped under the control of the process control unit 73, the raised futons A fall by their own weight, thereby changing the position of the futons A with respect to the drum 4 and eliminating uneven drying. Uniform drying can be performed efficiently in a relatively short time.

The above-mentioned drying step is performed by the electric control device 71.
The predetermined time set in the timer 76 (7 minutes in the present embodiment) is continued, and when the predetermined time elapses, the process ends and the process proceeds to the next restoration process under the control of the process control unit 73.

In the restoring step, the operation of the blower 50 is the same as that in the drying step, and the exhaust amount is set to be larger than the forced exhaust amount in the steam step. In this restoration step, the rotation of the drum 4 is set lower than the rotation number in the drying step, and the drum rotates at a speed at which the centrifugal force acting on the futons A becomes smaller than the own weight of the futons A. Therefore, the futons A that have risen with the rotation of the drum 4 fall from the middle due to their own weight, and hit the futons A with the impact force of this drop.
By this beating operation, it is possible to restore from a state in which cotton or the like is crushed to a fluffy bulky state.

The rotation of the drum 4 in the restoring process may be continued in the normal rotation, but the rotation of the drum 4 may be alternately repeated at predetermined time intervals under the control of the process control unit 73. By repeatedly performing such forward and reverse rotations, the hitting operation can be performed evenly, so that the portion to be restored to the bulky state can be made uniform.

During the restoration process, the blower 50
Operates continuously, so that the hot air from the heater 34 is introduced into the housing 3, whereby the heating and drying of the futons A are continuously performed. Then, dirt and dust coming out of the futons A are removed by forced exhaustion by the blower 50 and collected by the filter 52.

The above-mentioned restoring step is performed by the electric control device 71.
The predetermined time set in the timer 76 (10 in this embodiment)
(Minutes), and ends when the predetermined time elapses, and returns to the initial state. That is, the process control section 73 stops the drum 4 and the motor 50 'of the blower 50, respectively. When the rotation of the drum 4 is stopped, the supply of the compressed air to the door closing air cylinder 15 is stopped by the control of the door opening / closing control unit 72 of the electric control device 71, and the pressing operation is stopped. Is retracted by the urging of the coil spring 13, the solenoid valve 75 is subsequently opened, the air cylinder 16 for elevation is operated, and the door 2 is raised. Therefore, the input port 6 of the housing 3 is opened, and the user can take out the reproduced futons A from the drum 4.

In the embodiment described above, the door 2 is raised and the slot 6 is opened to stand by, and when a predetermined amount of coins is inserted, the start switch 62 is activated. Control device 71 is a checkout device 7
The start switch 62 is activated on condition that the payment signal from 0 is received and the payment of the predetermined amount is completed, and the drive source is operated on condition that the start signal from the start switch 62 is received. The door second
What is necessary is just to be provided with the door opening / closing control part 72 which changes from a state into a 1st state, and closes the dry insertion part, and the process control part 73 which controls a rotary drive mechanism and a hot-air supply mechanism. Therefore, the following procedure may be set.

In the initial state where the power of the reproducing apparatus 1 is turned on,
The door 2 may be set to the first state in which it is lowered. In this case, there is no need to operate the door closing air cylinder 15 to press the door 2 against the front surface of the housing, as long as no foreign matter can enter the drum 4 from the charging port 6. 2 may be pressed.

In this state, when the user inserts a coin or the like, the payment signal from the checker 70 is received by the door opening / closing controller 72 of the controller 71 to determine the end of the payment of the predetermined amount. The door opening / closing control section 72 operates the solenoid valve 75 of the lifting / lowering air cylinder 16 to convert the door 2 to the second state to open the insertion port 6 and to activate the start switch 62.

Then, the user puts the material A to be dried into the drum 4 through the opened inlet 6, and operates the start switch 62 in this state. The door opening / closing control unit 72 operates the solenoid valve 75 of the lifting / lowering air cylinder 16 on condition that a start signal from the start switch 62 is received.
