DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to relates to a water washing a washing machine, a manufacturing method and a washing method of a washing for ozone water using ozone or ozone (O _3).

[0002]

2. Description of the Related Art Ozone has been attracting attention as an environmentally friendly substance. Even if ozone is decomposed, it only turns into oxygen, and it can be said that there is no toxicity unless it is concentrated ozone.
In addition, ozone is a very unstable gas in which one oxygen atom is attached to an oxygen molecule, and has a feature that it easily releases one oxygen atom to become stable oxygen. The oxygen atoms released at this time tend to react with the surrounding substances, break the chemical bonds of those substances and break them apart, or make holes on the surface of microorganisms such as bacteria and kill them. It is well known that the binding of oxygen atoms to other substances is called oxidation.Ozone has a very strong oxidizing power, so it can be used for various purposes such as bleaching, disinfection and removal of mold odor. have. For this reason, ozone is also used for dry cleaning in which clothes are washed with a petroleum-based dry cleaning liquid.

In general, since the dry cleaning liquid is used repeatedly, fine dust such as lint and dust released from the laundry is mixed in the dry cleaning liquid once used. For this reason, the dry cleaning liquid in which these fine dusts are mixed is filtered by a filter and reused.

[0004] However, there are fine particles that cannot be completely filtered even by a filter, and such fine particles are often reused while being mixed in the dry cleaning liquid. For this reason, the dry cleaning liquid reused several times becomes so polluted that it can no longer be used, and only waits for disposal. However, it is a problem how to dispose of the wastewater, and it is not possible to flow the polluted dry cleaning liquid into the sewer because it causes river pollution.
Therefore, ozone is used as a means for cleaning such a dry cleaning liquid. For example, there is known a means for cleaning a dry cleaning liquid using an ozone purifier as disclosed in Japanese Patent Application Laid-Open No. 6-154478.

[0005] However, even though the dry cleaning liquid is cleaned by using ozone, it is impossible to clean the liquid before use, and it is necessary to dispose of the waste liquid eventually. Further, since the dry cleaning liquid is a petroleum-based solvent as described above, it must be handled carefully for disaster prevention, and is more troublesome than water. As described above, even with the cleaning means for the dry cleaning liquid using the ozone purifier, the problem of the treatment of the dry cleaning liquid still remains, and it is hard to say that the handling thereof is easy.

[0006] Whether the laundry is dry-cleaned or water-washed depends on the type of clothes and the type of dirt. Speaking of cloth, for example, in the case of clothes with a mark for dry cleaning such as wool, the cloth will be damaged unless dry cleaning is performed, and if it is dirt, in the case of oil stains such as oil stains, It is hard to fall unless dry cleaning.

[0007] Aside from clothing that originally had to be dry-cleaned, clothing originally made of water-washable fabric, even if the stain was oil-based, If the dirt can be removed by washing with water, the use of the dry cleaning liquid is reduced accordingly, which is preferable in terms of environment and ease of handling of the washing liquid.

Therefore, as described above, the use of an ozone purifying device which is already used for dry cleaning, has an excellent bleaching action, etc., and can sufficiently clean oil-based dirt is also applied to a water-washing machine by washing with water. There is an expectation that it can be done. However, the solubility of ozone is 49 ml /
It is 100 g H ₂ O (0 ° C.) and is a substance that is hardly soluble in water. For this reason, it has been considered that laundry cannot be treated using ozone in a washing machine that is washed with water.

However, the inventor of the present invention has concluded that ozone itself has an excellent bleaching action and the like as described above, and can sufficiently clean even oil-based dirt. I was very reluctant to decide that it was impossible just because of the differences.

[0010]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above circumstances, and the problem to be solved is to provide a washing machine by washing with water which has been considered impossible. It is an object of the present invention to provide a washing machine for processing laundry using ozone, a method for producing ozone water for washing which is extremely effective, and a method for washing using ozone.

The storage tank is provided with a stirring means for stirring the washing water stored in the storage tank.

In the present specification, "fine bubble-like ozone"
The reason is that the contact area between the washing water and the ozone is made as large as possible so that the ozone efficiently reacts with the dirt attached to the clothes and the like. Therefore, it does not impose any restrictions on the size of the bubbles,
Needless to say, it is better to be as small as possible. Similarly, the “ozone supply device” may be any device capable of producing and supplying ozone or ozone gas, and there is no limitation on the production method and the like. As a manufacturing method, for example, there is a so-called silent discharge method. Similarly, the structure of the "stirring means" is not limited as long as it can stir, ie, stir, the washing water. For example, a structure that stirs inside the storage tank or a structure that stirs by shaking the storage tank itself may be used. Further, a circulating stirring structure may be used in which the washing water is taken out of the water storage tank, ozone is supplied thereto, and then the water is returned to the water storage tank.

According to such a configuration, the ozone in the form of fine bubbles supplied to the storage tank via the hose moves together with the washing water stirred in the storage tank by the stirring means. For this reason, the ozone which has come out of the hose cannot linearly float in the water stored in the storage tank, and the time in which the ozone stays in the water is prolonged. The longer the ozone, the more opportunities for the ozone to come into contact with dirt, various germs, etc., so that the reaction efficiency is increased, and as a result, a sufficient washing effect is exhibited.

[0014] In this way, even if the garment has oil-based dirt, if the garment is made of washable fabric, the dirt can be removed by washing with water. In other words, what had to be washed using a dry cleaning liquid can be covered with water.

The effect that it can be obtained is obtained.

According to a third aspect of the present invention, in addition to the structure of the first or second aspect, the agitating means compresses ozone supplied from the ozone supply device by a compressor. It is formed by arranging the hose in the storage tank so that the washing water in the storage tank is swirled by the force when the ozone compressed in this way is ejected from the hose into the storage tank. And

According to this structure, the first aspect of the present invention is provided.
Or, in addition to the effect of the configuration described in any one of 2, the ozone supply and the agitation of the washing water can be performed simultaneously only by disposing the hose in the storage tank, so that the structure of the storage tank and its surroundings is simple. Is obtained. As the “compressor” in this specification, any compressor can be used as long as it can compress ozone, regardless of its name. Any of these may be used.

According to a fourth aspect of the present invention, in addition to the structure of the third aspect, a plurality of hoses are provided.

According to the above construction, a third aspect is provided.
In addition to the effects of the described configuration, ozone can be ejected into the washing water from a plurality of locations, so that ozone can be supplied more efficiently than when only a single hose is used. The effect of being able to swirl more efficiently is obtained.

According to a fifth aspect of the present invention, in addition to the configuration of the third aspect, the storage tank is cylindrical, and the hose connected to the storage tank has a cylindrical shape. The ozone outlet is arranged along the circumferential direction on the bottom surface of the storage tank, whereby the stirring means is configured to generate a swirl in the storage tank.

According to the above construction, a third aspect is provided.
Or, in addition to the effects of the configuration described in any one of 4 above, ozone can be moved from the bottom surface of the storage tank, that is, the deepest part, in the circumferential direction, that is, the direction in which the movement distance is the longest, so that the ozone is stored for a longer time The effect of being able to stay inside is obtained.

According to a sixth aspect of the present invention, in addition to the configuration of the second aspect, the agitating means compresses ozone supplied from the ozone supply device by a compressor. The rotating body provided at the end of the hose is rotated by the force when the ozone is ejected from the end of the hose, whereby the washing water in the storage tank is swirled.

With such a configuration, a second aspect is provided.
In addition to the effect of the configuration described above, the rotation of the rotating body swirls the washing water, and as a result, ozone can be retained in the storage tank in the same manner as the effect of the configuration of the fifth aspect.

According to a seventh aspect of the present invention, in addition to the structure according to any one of the first to sixth aspects, the washing machine is directly connected to the ozone supply device by a separate hose. And

According to this structure, the first aspect of the present invention is provided.
In addition to the effects of the configuration according to any one of Items 6 to 6, ozone can be further added to the washing water containing ozone supplied to the washing tub, and the effect that washing water with a higher ozone content can be produced. Can be

In the method for producing ozone water for washing according to the eighth aspect of the present invention, a stirring action is applied while supplying fine bubble ozone to the washing water stored in the storage tank. The ozone is retained in the washing water.

With this configuration, it is possible to produce ozone water for washing in which ozone is convected for a long period of time, so that the ozone water can be used for washing (washing) various things. That is, the ozone in the form of fine bubbles supplied to the storage tank via the hose moves together with the washing water stirred in the storage tank by the stirring means. For this reason, the ozone which has come out of the hose cannot linearly float in the water stored in the storage tank, and the time in which the ozone stays in the water is prolonged. The longer the time, the greater the chance of the ozone coming into contact with dirt and various germs, thereby increasing the reaction efficiency and consequently exhibiting a sufficient washing effect.

In the washing method according to the ninth aspect of the present invention, the washing water in which the ozone stays is added by applying a stirring action to the washing water stored in the storage tank while supplying fine bubble ozone. The method comprises a first step of producing ozone water and a second step of washing laundry using ozone water for washing.

By adopting such a configuration, even if the garment has dirt that is difficult to remove such as oil,
If it is made of a washable fabric, the effect is obtained that the stain can be removed by washing with water. In other words, what had to be washed using a dry cleaning liquid can be covered with water.

According to the tenth aspect of the present invention, the ozone compressed by the compressor is ejected into the washing water stored in the storage tank in the form of fine bubbles.
The first step of producing ozone water for washing in which ozone stays due to the stirring effect obtained thereby, and the second step of sending ozone water for washing to the washing tub of the washing machine and washing the laundry in the washing tub. It is characterized by consisting of.

With this configuration, ozone can be moved from the bottom of the storage tank, that is, the deepest part, in the circumferential direction, that is, the direction in which the movement distance is the longest, so that the ozone is stored in the storage tank for a longer time. And the effect of increasing the washing effect by that amount can be obtained.
