Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry cleaning device, and more particularly to a clothes drying and finishing machine which is used for both drying and finishing.

[0002]

2. Description of the Related Art The process of dry cleaning mainly comprises washing, deliquoring, drying and finishing. Conventionally, a tumbler dryer using a rotary drum, a box-shaped static dryer, or the like has been used in the drying process. The tumbler dryer is a machine that oscillates and stirs clothes in a rotating drum while supplying hot air to dry the clothes. In addition, the static dryer is a dryer in which hot air is supplied into the box for drying while the clothes are placed on the shelves arranged inside the box or the clothes are hung on a hanger. is there.

The finishing process is a process of stretching wrinkles on the dried clothes and pressing them. A steam box finishing machine or a steam tunnel finishing machine is used to remove fine wrinkles on the clothes before pressing. The steam box finishing machine injects steam into the box with clothes placed on shelves arranged inside the box or hanging clothes hanging on a hanger to perform so-called finishing. It is a thing. Further, the steam tunnel finishing machine finishes by spraying steam in the process in which clothes hung on a hanger are conveyed by a conveyor.

[0004]

As described above, since the drying and finishing steps are conventionally performed by using independent devices, it takes a lot of time to transfer the clothes, and the time required for the drying and finishing is long. . Furthermore, in recent years, with the use of chlorine-based synthetic solvents such as CFCs becoming difficult due to environmental damage and adverse effects on the human body, petroleum-based solvents have been reconsidered as dry cleaning solvents. Since the boiling point is very high, it takes a long time to completely remove the solvent remaining on the clothes. Therefore, the dry finish of the cleaning using the petroleum-based solvent takes a longer time and the productivity of the cleaning is deteriorated.

The present invention has been made to solve the above problems, and its purpose is to efficiently perform the drying and finishing steps in the same apparatus, and especially to perform cleaning using a petroleum solvent. It is an object of the present invention to provide a clothes drying finishing machine capable of executing the clothes drying finishing performed in a short time.

Another object of the present invention is to provide a clothes drying finishing machine which can perform safe drying with a low risk of ignition in cleaning with a petroleum solvent having high flammability.

In a box-type clothes drying finisher that performs a finishing process for stretching the clothes, a) a drying finishing chamber formed inside the box-shaped casing; b) an outside air intake port; and c) outside air taken in from the outside air intake port. An air-blowing means for heating and heating the dry finish chamber into the dry finish chamber; d) an exhaust port for discharging the gas in the dry finish chamber to the outside; and e) for injecting steam into the dry finish chamber. A steam injection port, f) a steam control valve for controlling the supply of steam, g) a temperature sensor for detecting the temperature in the drying finishing chamber, and h) controlling the air blowing means and the steam control valve, respectively. Hot air in the dry finishing chamber And 1st step of keeping the temperature in the drying finishing chamber within a predetermined range based on the temperature detected by the temperature sensor, and the steam injection is stopped after supplying the steam for a predetermined time with the air blow stopped. Operation control for sequentially executing a second step of maintaining the state for a while and a third step of controlling the air blower to supply hot air into the drying finishing chamber and keeping the temperature of the inside of the drying finishing chamber within a predetermined range. Means and are provided.

In the clothes drying finisher according to the present invention, the operation control means controls the opening and closing of the steam control valve and the driving of the blowing means according to a predetermined program, while performing the processing from the first step to the third step. Execute sequentially.

That is, in the first step, while the steam and hot air are continuously supplied to the drying finishing chamber, the intake amount of outside air is adjusted so that the temperature in the drying finishing chamber falls within a predetermined range. Next, in the second step, first, only steam is supplied into the drying finishing chamber in a state where hot air is stopped so that the drying finishing chamber is sufficiently filled with the steam. After that, the steam is stopped and the clothes are kept steamed for a while.

In the subsequent third step, while only hot air is continuously supplied to the drying finishing chamber, the intake amount of outside air is adjusted so that the temperature in the drying finishing chamber falls within a predetermined range. Third
After completion of the process, the drying finishing chamber is opened and low temperature outside air is supplied. In the clothes dryer and finisher according to the present invention, the drying and finishing, which are conventionally separate steps, are simultaneously completed by this series of process steps.

Therefore, not only the labor of transferring the clothes from the dryer to the finishing machine is unnecessary, but also the drying and finishing time can be shortened. In particular, the temperature of the clothes rises rapidly when the steam is sprayed onto the clothes and is hit by hot air, and the petroleum solvent having a high boiling point is easily volatilized from the clothes, so that the drying time is greatly shortened. Further, since the hot air drying is performed almost always while supplying steam, the humidity in the drying finishing chamber is extremely high, and static electricity is hardly generated due to friction between clothes. Therefore, the risk of ignition of petroleum-based solvents is extremely low.

The clothes drying finishing machine is provided with a hanger hook for hanging laundry in the drying finishing chamber and a swinging means for swinging the hanger rack, and at least any one of the first to third steps. It is preferable that the clothes hung on the hanger be rocked at the center. According to this, since the steam and hot air hit the clothes evenly, the drying and finishing are performed more efficiently.

Further, the finish effect can be improved by providing the steam injection ports at the upper part and the lower part of the inner surface of the dry finishing chamber. In particular, by performing steam injection from the upper part, an effect of removing the solvent odor of a relatively thick part such as a shoulder pad of a suit can be obtained.

Furthermore, it is more preferable to provide a solvent recovery means for recovering the solvent contained in the gas discharged from the exhaust port. As the solvent recovery means, known ones such as exhaust gas condensation type and adsorption type are used. According to this, since the solvent remaining on the clothes is almost completely recovered, the resources can be effectively used and the adverse effect on the surrounding environment can be prevented.

The operation control unit 40 sequentially executes the following steps in accordance with the operation program, whereby the clothes are dried and finished.

(I) First Step (Hot Air Steam Drying Step) The hot air steam drying step is a step of evaporating the solvent impregnated in the clothes by the hot air while applying steam to the clothes. In this step, the steam solenoid valve 34 is opened, and steam is simultaneously supplied from the upper steam injection port 11 and the lower steam injection port 12 into the drying finishing chamber 10. Further, the fan 25 is started, and hot air is discharged from the hot air outlets 13, 14, 15 at three locations.
Is supplied to the dry finishing chamber 10. The temperature inside the drying and finishing chamber 10 at this time is detected by the temperature sensor 43, and the inlet opening / closing valve 44 is controlled so that the temperature is maintained at 60 to 70 ° C.
The amount of hot air is adjusted by controlling the opening and closing of. That is,
Hot air enters or outside air enters directly. The gas containing the solvent volatilized from the clothes is sucked from the drying finishing chamber 10 through the suction port 16 and discharged to the outside from the exhaust duct 26. The operating time of this hot-air steam drying process is about several minutes.

(Ii) Second Step (Steam Finishing Step) The steam finishing step is a step in which the dry finishing chamber 10 is kept filled with steam for a while, and the clothes are steamed to smooth out wrinkles in the clothes. is there. In this process, first, the fan 25 is stopped, the steam solenoid valve 34 is opened following the first process, and the upper steam injection port 11 and the lower steam injection port 12 are opened.
From the same time, steam is supplied into the dry finishing chamber 10. On the other hand, the inlet opening / closing valve 44 is closed. As a result, the dry finishing chamber 10 is filled with steam. This steam injection is continued for about 30 seconds, and the steam solenoid valve 34 is closed while the dry finishing chamber 10 is filled with steam. Thus, the vapor retention state of the drying and finishing chamber 10 is maintained as it is for about 10 to 20 seconds.

(Iii) Third Step (Hot Air Finishing Step) The hot air finishing step is a step in which hot air is again applied to the clothes to perform final drying while finishing. In this step, the steam solenoid valve 34 is closed and steam injection is not performed. On the other hand, the fan 25 is operated and the inlet opening / closing valve 4
Since 4 is opened, hot air is discharged from three hot air outlets 13,
It is supplied from 14 and 15 into the drying and finishing chamber 10. However,
At this time, as in the first step, the temperature inside the drying finishing chamber 10 is detected by the temperature sensor 43, and the amount of hot air is controlled by controlling the opening / closing of the inlet opening / closing valve 44 so that the temperature is maintained at 60 to 70 ° C. Is adjusted. The operation time of this hot air finishing process is 2 to
It will be about 4 minutes.

(Iv) Cooling Step When the above steps are completed, the door 19 is opened and the outside air is introduced into the drying finishing chamber 10, and the temperature in the drying finishing chamber 10 rapidly equilibrates with the outdoor temperature.

During each of the above steps, the vibration motor 27 is rotationally driven, and the rotation of the motor is transmitted to the hanger receiver 17 as front and rear vibrations, whereby the clothes hung on the hanger swing.

An example of a specific operating time of the clothes drying and finishing machine described above is as follows. When drying suits such as suits hanging on hangers, hot air steam drying process 7 minutes,
In the steam finishing step, 30 seconds of steam injection, 10 seconds of closed steaming, and 2 minutes and 20 seconds of hot air finishing step, a total of 10 minutes, each of which 13 suits hung on a hanger can be sufficiently dried. Further, when a sweater is placed on a shelf provided in the drying finishing chamber 10 without using a hanger (drying is not performed) and drying finish is performed, hot-air steam drying process is performed for 5 minutes, and steam injection in the steam finishing process is performed. 30 seconds, closed steaming 10 seconds, hot air finishing process 1 minute 20 seconds for a total of 7 minutes, 1 on each of 5 shelves
The dot-mounted sweater can be sufficiently dried. Of course, by appropriately adjusting the operating time according to the amount of clothes and the vapor pressure, it is possible to select the suitable drying finishing condition for each.

By the way, in the case of the conventional tumbler dryer, in order to reduce wrinkles on the clothes as much as possible, it is necessary to send cold air after the hot air drying to cool the clothes gradually, and a cooling time of about 20 minutes is usually required. Therefore, according to the clothes dryer and finisher of the present invention, not only the drying but also the finishing can be performed in about half the time or less as compared with the conventional tumbler dryer.

If the gas in the dry finishing chamber 10 is discharged to the outside through the exhaust duct 26, the gas is passed through the solvent recovery device to recover the solvent contained therein. The recovered solvent can be used again in the cleaning step, and the problem of environmental pollution due to exhaust gas is eliminated.
