Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a (U) method for washing futons, and more particularly to a (R) method for washing futons that allows the futon to be washed in its original form.

[Technical background of the invention and its problems]

Conventionally, there are 8 methods for washing futons: separating the cloth cover and the inner futon cotton, washing them separately, drying them, and sewing them again, or spraying a detergent solution onto the surface of the futon while leaving the original shape. Methods such as brushing, washing, and drying are used for attaching, but the method described in the song title requires troublesome disassembly and sewing work, resulting in high costs and damage to the cotton mt. Although this method is simple, it has the disadvantage that the cotton inside the futon is not sufficiently cleaned and the restorability is also poor.

Until now, no method has been developed for washing futons in their original form, and at best surface cleaning is carried out by spraying or brushing the surface of the futon with a cleaning solution.

This is because, unlike general laundry, it is difficult to wash futon cotton. Futon cotton is raw cotton, and during the cotton manufacturing process, the cotton and the wood are combined into one thin piece of cotton due to the natural curling force of the cotton, and then several layers of this thinly combined cotton are layered together. It was commercialized as cotton. Therefore, when water is absorbed into cotton, it shrinks, and at the same time, the cotton itself becomes stiff. Furthermore, once cotton has absorbed water and shrunk, drying it will not return it to its original state. In addition, the cotton core has a cavity that gives the cotton properties of heat retention and elasticity, and it is important to wash the cotton without allowing water, detergent solution, etc. to penetrate into this cavity.

This happens once water, cleaning fluid, etc. seep into the cavity.
This is because it is extremely difficult to completely remove this. For this purpose, it is necessary to quickly pass water and detergent liquid onto the cotton surface to perform a cleaning action.

[Purpose of the invention]

The present invention has been made with due consideration given to the properties of futon cotton, and it is possible to sufficiently wash futon bedding from the surface to the futon cotton inside the futon in its original form, and to clean the bedding from the original futon cotton. The purpose of the present invention is to provide a method of washing a futon that can restore the futon to its original condition.

[Summary of the invention]

The present invention relates to a futon washing method that allows the futon to be washed completely, in which the futon is spread out almost horizontally, a detergent solution is sprayed from above, the futon is placed in a centrifuge, and the futon is rotated while the futon is inside the futon. The washing process, rinsing process, and dehydration process are carried out sequentially for a predetermined period of time, then the futon is taken out from the centrifuge + mi, dried, and the dried futon is placed in a restoring machine and the natural falling movement is repeated while blowing high-temperature air to make the futon. It is characterized in that it consists of restoring cotton.

According to the present invention, not only the surface of the futon but also the futon cotton inside the futon can be thoroughly washed while keeping the futon in its original form, and the futon cotton can be satisfactorily restored to its original state.

A plurality of protrusions 35 are provided within the rotation 1ji34 so as to face radially inward. For example, heat exchange steam lines 32a and 32b are connected to the heater 32.

The futon washing method is comprised of a combination of processing steps by the surface cleaning device, centrifugal separator 17, drying device 20, and restoring machine 30 described above.

FIG. 5 is a block diagram showing each washing process in the futon washing method according to this embodiment.

First, in the pretreatment process, doji threads are passed through the surface of the futon and stapled at appropriate locations to fix the futon cotton to the cover cloth. Next, if the cover cloth has stains such as oil stains, the stains are removed using a known stain remover, for example, an ultrasonic stain remover.

After performing such a pre-treatment process, the futon surface cleaning process begins. The surface cleaning of the futon is mainly for cleaning the cover cloth, and is carried out using a surface cleaning device shown in FIG.

When the futon B is placed on the conveyor belt 11 that is being driven in the direction of the arrow and transferred into the washing device 13, the washing device 13
High-pressure water is sprayed from a water spray 14 within the interior, and a neutral detergent solution is sprayed from a detergent solution spray 15. In this case, the jetting water pressure is preferably about 5 Kl/cti, and the detergent solution is preferably about 12% alcohol neutral detergent. The surface of the futon B is effectively cleaned by jetting high-pressure water and detergent and brushing with the brush 16.

The futon B whose surface has been washed by the surface washing device in this manner is placed in a centrifugal separator 17 as shown in FIG. 2, with its surface brought into close contact with the inner shell 17a of the centrifugal separator 17.

After putting the futon B into the centrifuge 17, the centrifugal valve eiJi
Increase the rotation speed of the machine 17 to about 70 ORPM and drive it for about 1 minute to allow the detergent solution to penetrate into the futon cotton inside.
Furthermore, this is quickly passed through and discharged from the discharge port 17d. This quickly cleans the cotton inside the futon. Then, while maintaining the same rotation speed, about 5
Inject K9/ctA drought. This injection is approximately 2
The detergent solution is rinsed away for ~3 minutes. After this rinsing process is completed, the same rotational speed is maintained for about 5 minutes to perform dehydration. Through this series of steps, the futon is thoroughly cleaned to the inside and dirt is completely removed.

After the dehydration is completed, it is desirable to spray the softener solution from the injection nozzle for about 1 minute at a pressure of about 4 Kl/ci while maintaining the rotational speed of 700 RPM. As this softener liquid, a laundry softener liquid containing a cationic activator as a main component is used. After the injection of the softener liquid is finished, the machine is rotated continuously for about 3 minutes to allow the softener liquid to completely permeate and drain the excess liquid.

Control of the rotation speed, drive time, etc. of the centrifugal separator 8117 is performed by a control panel (not shown) equipped with a timer or the like.

Futon B processed in the centrifugal separator 1111 and 17 in such a process is taken out from the centrifuge 17 and enters a drying process.

This drying step can be carried out by air drying or, as shown in FIG. 3, by placing the cloth in a futon drying device 20 and drying it at a low temperature. Drying room 2
Using the heat exchanger unit 22 and the blower fan 23, 1 ffl was sprayed onto the futon B carried in and placed in the futon B, and the futon B was dried at a temperature of 60 to 70° C. for about 3 to 4 hours. The reason for drying at such a low temperature is that if it dries rapidly at a high temperature, the moisture in the futon cotton will evaporate rapidly, causing the cotton to become stuffy and change in quality, or come out from the surface of the cover cloth, causing the tips to break and cause small pieces. This is because they may form in the form of flies and attach to the surface of the futon. In particular, in the case of synthetic cotton, the restoring power of cotton is significantly lost. This drying process reduces the moisture content in the futon cotton to approximately 20%.
It will be about 25%.

The futon thus dried at low temperature is then put into a restoring machine 30 as shown in FIG. 4, and the futon cotton is restored.

The futon B placed in the rotating barrel 34 of the restoration machine 30 is heated to a temperature of 100 to 120° C. by the heater 32 and fan 33 while rotating the rotating barrel 34 at a low rotation speed of about 20 to 30 PPM. It is dried by blowing high-temperature air. The futon B in the rotation 1t134 is lifted upward by the protrusion 35 and falls naturally, and this natural falling movement promotes the restoration of the futon cotton. By rotary drying the futon in the restoration machine for about 15 to 30 minutes in this way, the water in the futon cotton is completely removed, and the futon cotton can be completely restored using the drop caused by natural fall. .

In this way, according to this embodiment, the futon bedding can be washed in its original form without being dismantled.

[Effects of the Invention] As explained above, the present invention takes into account various problems that occur when washing futons and provides technical means to solve them. Bedding can be washed in its original form without being disassembled, making the work easier and faster than conventional washing methods, and reducing costs. In addition, not only the cover cloth but also the cotton inside the futon can be completely washed, making it extremely hygienic. In addition, the restoration of the futon cotton is performed well, and the futon bedding can be regenerated to look like new.
