[Field of Invention]

The present invention relates to a washing machine having a washing tank containing far infrared ceramic and chitosan.

In particular, the present invention relates to a washing machine for imparting a fiber softening effect to the washed fibers after washing of the laundry by a washing machine having a washing tank containing the far infrared ceramic and chitosan of the present invention.

More particularly, the present invention relates to a washing machine for imparting antimicrobial and antistatic effect to washed fibers after washing of the laundry by a washing machine having a washing tank containing the far infrared ceramic and chitosan of the present invention.

[Background of invention]

It is well-known that the use in a general household is remarkably common, and the washing of clothes which is repeated daily is simplified by the automation of the washing machine. In addition, the prevalence of washing machines has also reached a considerable level.

Conventionally, a washing tank of a washing machine is formed of a metal provided with plating or corrosion resistance, so problems such as corrosion occur for a long time, and recently, a washing tank is formed of synthetic resin instead of metal. Synthetic resins have been used very easily in forming washing tanks because of excellent water resistance, corrosion resistance and moldability.

However, in the washing tank formed of such a synthetic resin, the generation of static electricity is easy, so when washing synthetic fibers, static electricity may be generated in the laundry. In order to prevent this, the inconvenience of using an antistatic agent together with a detergent when washing by a washing machine is required. Not only does it cause sex but it also adds to the problem of environmental pollution.

In addition, a conventional washing tank has a large number of irregularities formed in the washing tank for smooth generation of water flow, and after a long time of use, detergents, antistatic agents or laundry residues may be deposited between these gaps.

In addition, the detergents commonly used are mainly anionic and nonionic detergents, and since the antistatic agent and the fibrous softener are mainly cationic, they may be deposited and combined with each other by their electrostatic forces after repeated use of the detergent and the antistatic agent. The combination of the detergent and the antistatic agent so deposited is easily attached to the washing tank formed of synthetic resin to form an environment in which bacteria or mold can live. Therefore, in the washing machine used for a long time, such deposits are usually formed, and bacteria or molds inhabit them, causing odors, and causing problems in the laundry after washing.

In addition, when washing using a conventional washing machine, it is also well known that it is not economical and environmentally disadvantaged because it uses detergents as well as antistatic agents and fabric softeners at the same time.

Accordingly, the present inventors have repeated the studies and experiments to impart the fiber flexibility, the antistatic effect and the deodorizing performance to the synthetic resin used in the washing tank to solve the above problems, ceramic and chitosan that emits far infrared rays to the synthetic resin forming the washing tank. As a result of the formation of the washing tank, the present invention was completed by significantly improving fiber flexibility, antistatic effect and deodorizing performance.

[Purpose of invention]

An object of the present invention is to provide a washing machine having a washing tank formed of a synthetic resin containing far-infrared ceramics and chitosan.

Another object of the present invention is to provide a washing machine having a washing tank provided with a fiber softening effect, an electrostatic suppressing effect, and a deodorizing performance.

Another object of the present invention is to provide a washing machine having a washing tank in which no odor occurs even after a long period of use.

[Summary of invention]

The present invention relates to a washing machine having a washing tank formed of a synthetic resin containing far-infrared ceramics and chitosan.

The synthetic resin is a conventional synthetic resin used to form a conventional washing tank, and contains a certain ratio of far-infrared emitting ceramic and chitosan. The far-infrared emitting ceramic emits far-infrared rays in the washing tank, and the released far-infrared rays give a fiber softening effect to the laundry to prevent shrinkage of the laundry after washing.

In addition, the chitosan forms a cationic environment on the inner surface of the washing tank exhibits an excellent antistatic effect. Furthermore, since the chitosan has excellent antimicrobial properties, it creates an environment where bacteria or mold cannot live in the washing tank, so that the generation of odor can be suppressed, thereby creating a clean and comfortable laundry environment at all times.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[Description of Specific Example of the Invention]

Washing tub according to the aspect of the present invention is formed of a composition in which far-infrared emitting ceramics, chitosan and ordinary synthetic resins are mixed in the following proportions:

2-6 wt% masterbatch for color toning

1 to 5 wt% of ceramic composition

In the above, the ceramic composition means a composition in which far-infrared emitting ceramic and chitosan are mixed. It can be understood that the far-infrared emitting ceramic and chitosan constituting the ceramic composition may be mixed with the synthetic resin separately. In the present invention, in order to homogenize the mixing and simplify the mixing process, the ceramic composition including far-infrared emitting ceramic and chitosan is first prepared, and the resulting ceramic composition is mixed with a color batching masterbatch to form a product obtained by mixing the far infrared rays. A wash bath containing the release ceramic was formed.

In the above, the ceramic composition is a mixture of far-infrared emitting ceramics and chitosan commercially available from Hyosung Ceramics in a ratio of 96 to 99% by weight: 1 to 4% by weight, and when the ceramic composition is less than 3% by weight, far infrared rays In addition to the low release effect, the content of chitosan is extremely low, so that the desired antimicrobial effect can not be obtained. If it exceeds 5% by weight, it is not economically desirable due to the concept of overuse, and the physical properties of the obtained synthetic resin are lowered. I can't. Preferably, the ceramic composition is 3% by weight.

The composition ratio of the ceramic composition is as follows:
