Abstract

PROBLEM TO BE SOLVED: To provide a fully automatic washing system in which only setting soiled objects to be washed on the system allows even a small volume of washes to be efficiently washed, rinsed and dried according to a state of each wash and subsequent treatment to each wash including a mothproof finish, deodorization and the like to be conducted during washing, and troublesome subsequent treatment including ironing, folding and the like is not necessary, and the washes are fully automatically treated up to storage. SOLUTION: The washing method is realized with higher effects on washing and rinsing and less damage to cloth even with strong water flow than those in a conventional method by not the conventional method strongly moving the washes in a washing liquid but fixing the objects to be washed and jetting the washing liquid onto the objects while the washing liquid is moved. After the washes are hanged on, washing the washes as they are stored allows a series of work from the subsequent treatment including washing, rinsing, drying, ironing out wrinkles, a waterproof finish and the like to the storage to be fully automated. The system decreases vibrations and noises during washing in comparison with those in the conventional method where a heavy load is fast rotated, providing effects decreasing vibrations and noises, decrease of housework and energy conservation.

TECHNICAL FIELD The present invention relates to a washing method.

[0002]

2. Description of the Related Art Currently, a general washing method for a washing machine is to fill a large washing tank with a washing liquid and put the laundry into it, and to rotate a propeller mounted under the container to create a rotating water flow of the washing liquid. There are many methods of washing by the difference between the speed of the laundry flowing inside and the speed of the rotating water flow. The specifications of the washing machine clearly specify the weight that can be loaded into the laundry, but the user rarely measures the weight in advance, and it is difficult to determine the appropriate amount until the laundry starts. As a result, the laundry tends to be overfilled and does not control the amount of wet laundry.Therefore, the water flow does not flow sufficiently between the laundry and it does not wash well as it rotates in a lump. Many. In addition, if the weight difference between the thrown items is large, there is a problem that the vibration becomes large when the laundry tank is rotated.

The rinsing method is the same as above. A washing tank containing washed laundry is filled with a large amount of fresh water, and is rotated while pouring fresh water. Rinse through wash water while diluting. In this case as well, the amount of laundry loaded becomes a problem. As for the dehydration method, there is a method of utilizing centrifugal force in many cases, and there is a method of spinning at high speed while pouring water into a washing tank containing laundry without washing water and simultaneously performing dehydration and rinsing by centrifugal force.

The method of drying is to put laundry into a rotating drum, rotate a container, and replace hot air with electricity or gas in the rotating drum at appropriate times to bring hot air into contact with the laundry. There is a method of heating the contained water to evaporate it.

In the conventional washing method, if the amount of laundry is not accumulated to a certain extent, wasteful water, detergent and power (electricity) increase, which is uneconomical. If the laundry is washed in a lump, it will take a large amount of mechanical work, and vibration and noise will also increase, which may be a problem in nighttime laundry and in small houses and condominiums.

Further, since the laundry is washed in one washing tank, the laundry which is hardly soiled and the laundry which is heavily soiled are often wasted because the same work is performed regardless of the degree of soiling. In addition, the rotation speed of the water flow in the washing tank, which has a great influence on the washing power, cannot be adjusted to the material of each laundry, so that the washing rate is average.

If the direction of the wash water flow is kept constant, the laundry and the wash water flow rotate in the same direction and rotate together, so that the water flow does not pass between the fibers. The washing water flow needs to change the rotation direction frequently to make it a turbulent flow, but it is a cause of damaging the fibers because the fibers are repeatedly bent and twisted.
It is mechanically difficult to change the rotating direction of a heavy-weight washing machine frequently by suppressing vibration and noise, and the performance of the washing machine is limited in terms of size and cost.

Since the fresh water used for rinsing is discarded without being reused, the method of diluting with a large amount of water is not economical. Also, when the laundry is dehydrated by centrifugal force, the laundry is bent and strongly pressed against the inner side of the drum while being piled up, which easily causes wrinkles and damages the fibers. When the drum is rotated and dried with high temperature air after dehydration, the laundry is dried by being repeatedly bent from the top of the rotating drum while being entangled while wrinkling while being overlapped. For this reason, there are some products that require the work of stretching wrinkles by ironing after drying.

Further, the process of drying and storing the washed product is conventionally required to stretch out wrinkles with an iron, and it is often the case that the product is folded and stored afterwards, so that wrinkles are stretched again before use. I often did Recently, many houses are equipped with a storage unit that can be stored in a suspended state.However, the suspended storage method will be adopted in the future due to the fact that it can be easily put in and taken out, it can prevent the clothes from losing its shape, and it is easy to manage. Seems to be the mainstream of.

[0010]

[Problems to be Solved by the Invention] Since it is more efficient than the current washing method, even a small amount of laundry can be efficiently washed according to the stain and quality of each laundry, and the storage method after washing is taken into consideration. Provide no way.

[0011]

SUMMARY OF THE INVENTION In consideration of the method of storing after washing, the present invention washes washing water and steam at an appropriate pressure and temperature according to the dirt and material of the laundry while suspending the laundry. The most main feature is that it can be stored in a suspended state after drying by a cleaning method of spraying on the item to be washed and a method of spraying gas or steam of appropriate pressure and temperature on the washed item while hanging. To do.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION The laundry is washed individually in a shape similar to that when the laundry is individually suspended on a hanger for use.
We propose a washing method that replaces the conventional method, which involves a lot of work to reduce the inefficiency of small amounts of laundry and to prevent damage to the fabric by storing it after drying and storing.

[0013]

[Example] With the entire fabric of the laundry stretched, for example, in the case of clothes such as jackets, hang it on a hanger with the stick of the hanger protruding from the tip of the sleeve Spread it and hang it on a hanger to put it in a jet-type washing machine. In the spray-type washing machine, the hanger is firmly fixed, and the hanging clothes are the thinnest. The washing nozzle, the rinsing nozzle, and the drying nozzle are sandwiched between the items to be washed in the front-back direction when viewed from the side. It is sandwiched in the front and back by a nozzle unit to which items such as nozzles necessary for washing work are attached.

A guide is attached to the nozzle unit so that the laundry does not run away by the jet flow. In addition, the nozzles attached to the nozzle unit are selected with an injection angle so that optimum cleaning can be obtained. A plurality of nozzles of the same type are attached in the width direction of the laundry so that the jet flow reaches the entire laundry, and the nozzle unit moves from top to bottom while jetting. A roller is attached to the nozzle unit on the opposite side to the moving direction. Lightly squeeze extra washing water etc. after washing that has been impregnated in the laundry to spread the fabric and stabilize the laundry to stabilize the laundry from top to bottom. Moving.

A plurality of nozzle units may be connected in the traveling direction and used, or a nozzle unit for cleaning and a nozzle unit for rinsing may be connected and moved. It is also possible to suspend a plurality of laundry items in a washing machine on a hanger and wash a large amount uniformly with a plurality of nozzle units.

[0016] Depending on how dirty the laundry is, the cleaning method may be steam cleaning when it is desired to remove odors such as sweat and cigarettes, or light dirt, and cleaning of terribly dirty material using a cleaning solution, either alone or The combination can be arbitrarily selected. Further, the injection pressure, the injection amount, the cleaning speed, the number of times of cleaning, etc. are set according to the degree of soiling of the laundry and the material of the cloth.

When the washing of the laundry is completed, the nozzle unit is moved away from the laundry and moved above the jet type washing machine. Similar to the washing operation, the laundry is sandwiched between nozzle units and moved downward while spraying a selected item such as fresh water or steam from a rinsing nozzle, and the rinsing operation is repeated as many times as necessary. In the rinsing work, the contamination level of the rinsing liquid that has fallen under the washing machine after spraying is detected as turbidity by an optical sensor, etc. at an appropriate measurement level, and the liquid temperature of the rinsing liquid, the injection amount, the injection pressure, the rinsing time, etc. are controlled. To do.

When the rinsing operation is completed, the nozzle unit is moved away from the laundry and moved above the jet type washing machine. Air and steam at an appropriate temperature are jetted from the nozzle for drying, and the same number of drying operations as those for cleaning and rinsing are repeated. In the drying operation, while appropriately ventilating the air in the washing machine, the temperature sensor attached to the nozzle unit measures the temperature distribution of the laundry hung on the hanger at an appropriate level, and the spraying temperature of the drying means, the spraying amount, The injection pressure is controlled to judge the completion of the drying work. In addition, by spraying a chemical solution such as waterproof and insect repellent after the drying operation, it is possible to enable long-term storage after washing.

The washed product can be stored by hanging it on a hanger so that the fabric is always stretched under its own weight, so that it is not necessary to correct wrinkles or to lose its shape.

There is no restriction on the shape of arrangement in these series of operations, and it is necessary to hang the hanger on a circular continuous rail to hang the clothes to be washed and to remove the washed clothes from the hangers manually. It is possible to circulate the hanger until storage and automate everything except for applying.

EFFECTS OF THE INVENTION The washing method according to the present invention allows washing from one sheet, and since the fibers are not bent or twisted unlike conventional kneading washing, the fibers are not easily damaged and a strong penetrating effect is obtained by jetting the washing liquid at a high pressure. The mechanical decontamination effect is much stronger than the conventional cleaning method of rotating in a detergent solution in a short period of time. If there is a slight amount of dirt, steam cleaning may be sufficient, but with the current washing method, there are many cases of washing together in a single washing tank regardless of the degree of dirt, so much water and detergent are wasted. . The washing method of the present invention in which pre-treatment and washing are performed according to individual laundry can be expected to have more water-saving effect, saving of detergent and shortening of washing time as compared with the conventional method. Even from an environmental point of view, the current washing method that uses a large amount of water and detergent is a big problem because it contaminates rivers and drains detergent that cannot be collected into the sea. Further, according to the washing method of the present invention, since the laundry once hung on the hanger will be wrinkled by its own weight, ironing after washing is unnecessary, and post-treatment such as folding and storing is unnecessary, and it is hung on the used hanger after washing. Save as it is. If necessary, after drying, insects, molds, odors, waterproofing, etc. can be processed, and the process from washing to storage can be automated.
