[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for drying and wrinkling of laundry.

[0002]

2. Description of the Related Art Among the above-mentioned apparatuses, in a box type apparatus, a dried product is suspended in a drying chamber, hot air which has been heated and dried by taking in outside air is blown toward the hanging chamber, and hot air containing moisture is discharged to the outside. There is something to release. In other words, it is forcibly dried at a stretch by a dry strong hot air. However, in the drying by this apparatus, in the laundry swollen by washing, there is a time lag in drying between the outer material and the lining, so that there is a problem that the shape collapses.

[0003]

SUMMARY OF THE INVENTION Accordingly, the main object of the present invention is to prevent the shape from being lost by drying in a state close to natural drying and to enable quick finishing.

[0004] The means for this is a structure in which the steam is extracted when the steam in the drying chamber becomes saturated or approaches the saturated state, that is, the heated air flow is circulated through the drying chamber having hanging means for hanging the laundry. A laundry drying apparatus for drying the suspended laundry, wherein the atmosphere in the drying room is replaced with a dry air more dried at predetermined time intervals during the circulation of the heated airflow in the closed state. It is a laundry drying device provided with replacement means.

The replacement means is provided in a circulation path formed outside the drying chamber, and is opened and closed at predetermined time intervals to switch the path of the heated air flow, to discharge an atmosphere containing a lot of moisture and to introduce dry air. It is preferable to use a damper.

Further, it is preferable that a swing mechanism for swinging the laundry is formed in the suspension means.

[0007]

In other words, according to the above-mentioned structure, first, the heating airflow is circulated in the drying chamber in the closed state for a predetermined time of the operation start. When the water evaporating from the laundry reaches a saturated state in the heated airflow (saturated or approaches a saturated state), the replacement means and the atmosphere containing much moisture and The dry air such as air outside the apparatus is replaced for a predetermined time. That is, intake and exhaust are performed. Then, the heating means is circulated again in the closed state, and when the saturated state is reached, the replacement means is driven again.
Is repeated until it is dried. That is, while a wet laundry is gradually dried while being steamed, a certain amount or more of excess water is quickly discharged.

For this reason, drying can be performed in a state close to nature,
There is no loss of shape as in the prior art, and the drying time is short. The working time can be greatly reduced as compared with a case where a heated air stream is continuously circulated in a closed state in order to dry while steaming.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a longitudinal sectional view showing an internal structure of a laundry drying apparatus 1 (hereinafter, referred to as an apparatus). On the front side, a drying room in which a suspending means 3 for suspending laundry 2 is laid horizontally. 4 is provided, and the upper and lower sides of the drying chamber 4 are connected by a circulation path 5 on the back side, so that the heated airflow circulates in the drying chamber 4 from top to bottom. At the bottom of the drying room 4, a steam spray pipe 6 for finishing is arranged, and a finishing process for extending wrinkles of the laundry 2 can be performed.

As shown in FIG. 2, the apparatus 1 has a door 7 on the front surface, and when the door 7 is opened, the door 7 is folded in two.
The drying chamber 4 is formed so as to be visible throughout the inside. Door 7
Has a structure in which the entire entrance is opened by opening to one side (the right side in FIG. 2), and an operation panel 8 is mounted above the door 7.

An outlet 9 is opened on the ceiling surface in the drying chamber 4 to communicate with one end of a circulation path 5 for circulating a heated airflow. Is equipped with a fan 10 for sending the atmosphere to the drying chamber 4.

In addition, a suction port 11 is opened at the center of the lower end on the back side in the drying chamber 4, and a fine mesh filter 12 is detachably attached. Suction port 1
1 communicates with the circulation path 5 on the back side, and the communication pipe 5a forming the circulation path 5 has a rectangular cross section,
It extends upward along the back surface of the drying chamber 4 so as to project to the rear side of the apparatus 1. Above the suction port 11 in the circulation path, a communication port 13 formed on one side (the right side in FIG. 3), and a detachable heater filter 14
, A heater 15 and a damper 16 are sequentially formed.

The communication pipe 5a is connected to the communication port 13 with the lower end of the exhaust pipe 17 connected thereto.
When the heating airflow flowing from the suction port 11 does not flow toward the heater 15, the heating airflow passes through the communication port 13. An exhaust port 18 at the upper end of the exhaust pipe 17 is opened in a round shape on the upper surface of the device 1.

The above damper 16 closes the circulation path 5 and opens and closes to allow outside air from outside the apparatus 1. The opening and closing drive is performed by an air cylinder 19 or the like as shown in FIG. Just do it. When the damper 16 does not block the circulation path 5, the damper 16 blocks the outside air suction port 20 opened on the back side of the circulation path 5, thereby preventing outside air that does not pass through the heater 15 from entering. In the figure, reference numeral 21 denotes a filter.

The above-mentioned suspending means 3 enables the laundry 2 to swing by switching a switch. Laundry 2
This is to allow the atmosphere inside the wafer to be positively exposed to the heated airflow, thereby making it possible to dry well, and to make it possible to satisfactorily remove wrinkles during finishing.

As shown in FIG. 4, the structure may be composed of a suspension locking member 22 and a swing mechanism 23. The suspension locking member 22 is a band-shaped member, and has recesses 22a formed at regular intervals on the upper end edge. The hook portion 24a of the hanger 24 can be hung without displacement. The swing mechanism 23 is located below the suspension locking member 22 and has a neck 24 b below the hook 24 a of the hanger 24.
Is reciprocated in the longitudinal direction of the hanging and locking member 22, and has a rod-shaped holding member 25 having holding portions 25 a for holding the necks 24 b of the hangers 24 hung on the hanging and locking member 22. And a motor 26 for driving the
And a cam 27, and a spring 28 for urging. The holding member 25 urged in one direction by a spring 28 attached to one end thereof periodically rotates the other end of the holding member 25 against the urging force of the spring 28 when the eccentric cam 27 rotates. Push. By repeating this, the swing of the laundry 2 is performed.

FIG. 5 shows the operation panel described above.
The operation method can be understood at a glance, and the driving operation is a one-touch operation by simply pressing a switch.
Reference numeral 31 denotes a temperature display in the drying room 4, and reference numeral 32 denotes a temperature setting dial set according to the cloth of the laundry 2. 33, 34
This is a switch for starting the drying processing, and the setting of the drying processing time is performed by a drying time setting dial 35. 36 is a display of the drying time, 37 is a switch for driving the swing mechanism 23, 38 is an air volume adjustment dial, 39 and 40 are switches for starting a finishing process, and 41 is a power switch.

In the drying process, automatic operation up to cooling can be performed simply by pressing one of the switches 33 and 34 described above. That is, the suction port 20 is closed and closed by the damper 16, and the fan 10 and the heater 15 are driven to change the atmosphere heated by the heater 15 to the fan 10.
And blows out from the top into the inside of the drying chamber 4. That is, the heating air flow is circulated in the closed state. If this operation is continued for a certain period of time, the atmosphere in the drying room 4 becomes saturated with water evaporating from the laundry 2, or approaches the saturated state. While discharging the atmosphere containing much,
Dry air (dry air) outside the apparatus 1 is introduced. That is, when the damper 16 closes the circulation path 5, the atmosphere flowing from the drying chamber 4 through the suction port 11 enters the exhaust pipe 17 via the communication port 13 and is discharged from the exhaust port 18 at the upper end. At the same time, dry air is sucked through the outside air suction port 20 by the suction of the fan 10. By continuously performing such intake and exhaust once every 15 seconds for 5 seconds, for example, excess moisture can be immediately discharged while performing steaming. After the predetermined drying time has elapsed in this manner, the damper 16 is defeated to introduce outside air,
Cool clothing.

As described above, the wet laundry 2 is gradually removed.
While drying while steaming, more than a certain amount of excess water is quickly drained, so it can be dried in a state close to nature and does not lose its shape as in the past,
Drying time is short. The working time can be greatly reduced as compared with a case where a heated air stream is continuously circulated in a closed state in order to dry while steaming.

Since the fan 10, the damper 16, the heater 15, and the communication port 13 with the exhaust pipe 17 are disposed in this order from the upper part in the circulation path 5, the intake and exhaust during the drying process, and
Cooling after drying can be performed by one damper 16, and the configuration can be simplified.

Further, the operation is started by the switches 33 and 34.
Since it is only necessary to press the key, it is easy with one touch, and since the display on the operation panel 8 is devised so that anyone can understand it, erroneous operation can be prevented and safety can be ensured. Moreover, since the mounting position of the operation panel 8 is higher than the door 7 on the front surface of the apparatus 1, there is almost no possibility that something hits and is pushed by mistake.
It is unlikely that the player will be operated with the forgotten to close. For this reason, the safety can be further improved.

The opening and closing of the damper 16 may be performed by detecting the humidity with a sensor, and the drying air introduced during the drying process may be heated to a low humidity state by another means instead of the outside air. Alternatively, an atmosphere obtained after the above may be used.
