Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a futon washing device, and more particularly to a futon washing device that can wash a futon in its original form.

[Technical background of the invention and its problems]

Conventional methods for washing futons include separating the fabric cover and the inner futon cotton, washing them separately, drying them, and then sewing them together again, or spraying detergent solution onto the surface of the futon while it is in its original form. Methods such as brushing, washing, and drying are used, but the former method requires troublesome disassembly and sewing work, resulting in high costs and damage to the cotton fibers, whereas the latter method is simple. However, there are disadvantages in that the cotton inside the futon is not sufficiently washed and the restorability is also poor.

Hitherto, no method has been developed for washing futons in their original form, and only surface cleaning methods have been carried out, such as spraying a cleaning liquid onto the surface of the futon or brushing it.

This is because, unlike general laundry, it is difficult to wash futon cotton. Futon cotton is raw cotton, and during the cotton manufacturing process, each cotton strand is bonded together to form a thin piece of cotton due to the natural curling force of cotton, and several layers of this thinly bonded cotton are layered. Together, they were 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 core without allowing water, detergent solution, etc. to penetrate into this cavity. Once water or detergent solution has penetrated into the cavity, it is extremely difficult to completely remove it. need to be done.

[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. An object of the present invention is to provide a washing device for futons that can satisfactorily restore the futon to its original state.

[Summary of the Invention] The present invention relates to a futon washing device that can wash a futon as a whole, and includes a surface cleaning device that includes a wash basin, a detergent liquid spraying means that sprays a detergent liquid from above the wash basin, and a washing machine that includes a washing basin and a detergent liquid spraying means that sprays a detergent liquid from above the washing basin. A centrifugal separator is connected to a supply source through a switching valve, and an injection pipe with an injection nozzle at its tip is inserted into the rotation chamber 11, and a drying chamber into which the futon is placed. , a futon drying device equipped with means for introducing warm air into the drying chamber, a hollow rotating body provided with a radial protrusion inside and into which the futon is thrown, and means for introducing hot air into the hollow rotation y.

It is composed of 13 combinations.

Next, the operation of this embodiment having such a configuration will be explained.

FIG. 5 is a block diagram showing a washing process when a futon is washed using the futon washing apparatus according to this embodiment.

First, in the pretreatment process, binding thread is 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 K'J/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 cleaned by the surface cleaning device in this manner is placed in the centrifugal compartment 11[17 as shown in FIG. 2, with its surface brought into close contact with the inner body 17a of the centrifugal compartment i11tm17.

After putting futon B into the centrifuge 17, it weighs about 4 kg/
Approximately 7% alcoholic neutral detergent solution is injected from the injection nozzle 18 through the injection pipe 19 at a pressure of crA, and 70R
Rotate for about 1 minute at a low rotation speed of about PM. This allows the detergent solution to fully penetrate into the interior of the futon.

Next, the injection of the detergent liquid is stopped, and the rotation speed of the centrifugal part 11tli17 is increased to about 70 ORPM, and the centrifugal part 11tli17 is rotated for about 1 minute, and the detergent liquid that has entered the inside is discharged from the discharge port 17d.

Subsequently, approximately 5 kg/cri of hot water is injected from the injection nozzle 18 while maintaining the same rotational speed. This spraying is carried out for about 2 to 3 minutes, thereby rinsing the detergent solution. 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.

When the dehydration is completed, the softener liquid is injected from the injection nozzle for about 1 minute at a pressure of about 4 Kg/cIi while maintaining the rotational speed of 700 RPM. As this softener liquid, a laundry softener liquid containing a stimulant activator as a main component is used. After the injection of the softener liquid is finished, the machine is continuously rotated for about 3 minutes to completely penetrate the softener liquid and discharge the excess amount.

Control of the rotation speed, drive time, etc. of the centrifugal separator 17 is performed by a control board (not shown) equipped with a timer and the like.

Further, the injection liquid to the injection pipe 19 can be selectively supplied by switching and controlling the on-off valves of tank units (not shown) in which the respective injection liquids of the separate U are stored.

A centrifugal valve is created through this process! The futon B processed in the li machine 17 is taken out from the centrifugal valve@machine 17 and enters the drying process.

This drying step is carried out by natural drying, but as shown in FIG. 3, the cloth is placed in a futon drying device 2o and dried at a low temperature. drying 2
The heat exchanger unit 22 and the blower fan 23 are used to blow warm air onto the futon B that has been carried into the room 6.
Dry at a temperature of 0 to 70"C for about 3 to 4 hours.The reason for drying at such a low temperature is that if you dry it rapidly at a high temperature, the moisture in the futon cotton will evaporate rapidly and the cotton will become stuffy. This is because they may deteriorate, or they may come out from the surface of the cover cloth and become cut off at the tip, forming small balls that adhere to the surface of the futon.

In particular, in the case of synthetic cotton, the restoring power of cotton is significantly lost. Through this drying process, the weight moisture content of the futon cotton is 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 rotation 1134 of the restoration machine 30 is heated to a high temperature of 100 to 120° C. by the heater 32 and fan 33 while rotating the rotary drum 34 at a low rotation speed of about 20 to 30 PPM. It is dried by blowing air. The futon B in the rotation 11134 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, the moisture in the futon cotton is completely removed, and the cotton on the fabric is completely restored using the drop caused by natural fall. can.

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

〔Effect 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. It can be washed in its original form without any cleaning, 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.
