Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wrinkle removal method for removing wrinkles by subjecting wrinkled clothing to steam injection and hot air contact, and then drying and finishing the garment.

Conventional wrinkle removing devices of this type are roughly divided into vertical hanging type and horizontal hanging type depending on the orientation of the clothes that are suspended from a drive chain and moved within the apparatus.

In the vertical hanging type, the front and back sides of the garment are parallel to the direction of travel of the garment, and in the horizontal hanging type, the front and back sides of the garment are perpendicular to the traveling direction.

In the vertical hanging type, the passage area in the cross section perpendicular to the direction of movement of the clothes in the wrinkle removal device requires a space equal to the maximum length of the clothes in the height direction and the thickness of the clothes in the width direction. This can also be done close to the garment, and can be done almost uniformly on the front and back of the garment. Moreover, in hot air drying finishing, by flowing a relatively small amount of hot air into the gap between the garment and the side wall of the device, the flow velocity in the gap can be increased, and a good finish can be obtained due to the vibration effect of the garment itself.

For the side-hanging style, the maximum length is required in the height direction, and the shoulder width is required in the width direction. Therefore, the space through which clothing passes through the device is considerably larger in the side-hanging type.

In order to remove wrinkles from clothes and dry them for a finished finish, it is necessary to provide a sufficient jet of steam to the clothes and contact them with high-speed hot air, but in the case of a horizontal hanging type, the space through which the clothes pass is smaller than in a vertical hanging type. Due to the large amount of steam, a large amount of steam injection and hot air are required, which increases the consumption of the heat source for heating the steam and the circulating air.

However, with the horizontal hanging type, it is possible to take a short hanger pitch of approximately 80 to 160 mm to hang clothes and pass them through the device continuously. The device itself has the advantage of being able to be designed compactly when finishing clothes, or when clothes are dehydrated for a short time after washing to remove wrinkles and finish drying.

On the other hand, in the case of a vertical hanging type, it is necessary to have a hanger pitch of about 500 to 600 mm, so in order to lengthen the residence time of clothes in the device and process a large amount, the device itself must be It becomes too large and difficult to accommodate in the factory layout.

Therefore, the side-mounted type is superior in terms of device size. However, in conventional horizontal hanging type equipment, the amount of hot air used for finishing drying is circulated in excess of the amount required for actual drying.

After steam is injected onto clothing, wrinkles will be smoothed out, but to maintain this state, the clothing itself must be vibrated during the final hot air drying process.
This vibration of the clothing itself is obtained by increasing the velocity of the hot air flow flowing over the clothing surface. For this reason, in the horizontal type, it was necessary to circulate a large amount of hot air as described above, and the excess air had to be heated and energy was wasted.

It is an object of the present invention to provide a method for removing wrinkles that can efficiently remove wrinkles using a small amount of hot air and a small amount of steam, while compensating for the above-mentioned drawbacks of the horizontal type.

In order to achieve the above object, the present invention provides an apparatus for removing wrinkles from clothes by feeding the clothes suspended perpendicularly to the running direction of the drive chain into a steam injection area and a hot air injection area. A large number of slit-shaped hot air injection ports are arranged in parallel at the top of the hot air injection area perpendicular to the direction of travel of the clothes, and hot air is jetted downward from each injection port. A hot air jet that forcibly vibrates each garment by making the interval between the openings and the interval between the garments suspended from the drive chain approximately equal, and passing a high-speed hot air flow between each garment. To provide a clothing wrinkle removing device in which zones are provided before and after a steam injection zone where hot air is not blown.

Embodiments of the device of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is the main body of the wrinkle removing device, which has an inlet part 2 and an outlet part 3 at both ends. Inside the main body 1, a steam injection area 4 is located in the middle part, and a hot air injection area 5 is provided on the inlet side and the outlet side. There are 6.

Reference numeral 7 denotes a guide rail for an endless drive chain, and a hanger 10 on which clothing 9 is hung is hung from a hanging hook 8 from the drive chain (not shown) running inside this guide rail, as shown in FIG. There is.

Reference numeral 12 in FIG. 2 is a blower provided at the rear of the main body 1, and a heat exchanger 14 is provided in a duct 13 connected to its discharge port. A large number of flat ducts 15 are connected to the upper end of this duct 13.

The flat ducts 15 are arranged in parallel at regular intervals, and their slit-shaped hot air injection ports 16 open into the ceiling 20 of the hot air injection area 5. this ceiling 2
0 is chevron-shaped as shown in FIG. 2, and there is a recess in the center into which the guide rail 7 fits, and an opening is provided at the bottom of the injection area 5, and this opening and the suction port of the blower 12 are formed in a space provided at the bottom of the main body 1. Connect at 17.

In addition, the ceiling 21 of the other hot air injection area 6 also has a large number of slit-shaped hot air injection ports 2 of flat ducts 22.
3 is open. Each of these flat ducts 22 also communicates with the blower duct similarly to the flat duct 15,
Hot air heated by a heat exchanger is injected into the injection area 6 from the injection port 23, but since its configuration is exactly the same as that in FIG. 2, detailed explanation will be omitted. Reference numeral 24 denotes a vertical steam introduction pipe provided along both side walls 25 of the steam injection area 4, and a plurality of steam injection nozzles 26 are provided therein.

In addition, each slit-shaped hot air injection port 16 and 2
The pitch of 3 is equal to the pitch of the garment 9 suspended by the hanger 10.

Now, as shown by the chain line in Fig. 3, the clothing 9 suspended from the chain hook in the guide rail 7 protruding from the front of the main body 1 moves laterally and enters the entrance part 2 through the entrance 27, and first Enter the hot air injection area 5.

Here, hot air generated by the blower 12 and heated by the heat exchanger 14 is injected downward from each injection port 16 as a hot air flow. This hot air flow forms an air curtain from each slit-shaped injection port 16 and hits each garment 9, and is sucked from the opening at the bottom of the zone 5, through the space 17 at the bottom of the main body 1, and into the suction port of the blower 12, repeating the cycle. .

Next, the clothes 9 entering the steam injection area 4 are sufficiently moistened by the steam ejected from the nozzles 26 on both sides, and then enter the next hot air injection area 6 to be dried, enter the outlet section 3, and exit from the outlet 28. to go out.

As described above, this invention arranges a large number of slit-shaped hot air injection ports perpendicular to the direction of travel of clothing so that hot air is jetted downward from each injection port, and the pitch of each hot air injection port is By making the pitch of the clothing suspended from the drive chain approximately equal and allowing the hot air jetted from the hot air jet to exist as a contact flow on the surface of the clothing, the hot air flow is constantly distributed in equal amounts to the space between the clothing items. . This equalizes the flow velocity of the hot air passing through the space between the garments, resulting in a constantly uniform vibration effect.

Further, since the hot air injection port is in the form of a slit, by appropriately selecting the width of the slit, the desired air speed can be obtained even if the air volume is kept to the minimum required for drying.

This desired wind speed is such that the clothing itself vibrates when the hot air comes into contact with the clothing, but a sufficient flow velocity can be achieved by blowing the hot air from the slit-shaped hot air jetting port. It will be done.

Furthermore, by surrounding the steam injection area with a hot air injection area consisting of a large number of slit-shaped hot air injection ports, the radiation of steam from the steam injection area can be prevented, and the steam injection area can be treated as a separate and independent entity. It has the effect of removing wrinkles from clothing by spraying a small amount of steam.
