In an electric washing machine with a structure in which the inner tub is attached to the inside of the outer tub, a closed space is created between the inner surface wall of the outer tub and the outer surface wall of the inner tub, which is an environment in which bacteria and bacteria can easily propagate. Also utilizes the sterilizing action of copper or a copper alloy as a means for suppressing the contamination of laundry by these bacteria and bacteria as much as possible. To explain this with reference to FIG. The inner surface wall 2a or a part of the outer surface wall 1b of the inner tank 1 is coated with a copper material or a copper alloy material. Specific examples of applying the copper material or the copper alloy material include applying fine wires or plates of copper or copper alloy to the inner surface wall 2a of the outer tank 2 or the outer surface wall 1b of the inner tank 1, or plating copper or copper alloy. Apply a film.

い。This will be described in more detail. Inner tank 1 and outer tank 2
Is made of stainless steel, the outer surface wall 1b of the inner tank 1 and the inner surface wall 2a of the outer tank 2 may be provided with fine wires or plates of copper or copper alloy, or may be plated with copper or copper alloy. .

を無電解技術を用いて取り付けるとよい。When the inner tank 1 and the outer tank 2 are made of synthetic resin, thin wires or plates of copper or copper alloy are synthesized on the outer surface wall 1b of the inner tank 1 and the inner surface wall 2a of the outer tank 2. It is advisable to attach the resin material at the time of injection molding, or to attach a copper or copper alloy plating film using an electroless technique.
【００１２】なお、内槽１や外槽２そのものを銅あるい

ンレス鋼を用いる場合、ステンレス鋼成分としてＣｕを
２〜６％添加した材料を用いるとよい。その理由は、Ｃ
ｕ添加量が２％以下の場合は、殺菌作用が小さく、実用
的でない。一方、Ｃｕ添加量を６％以上にすると、製鋼
技術の点で問題が残り、具体的には主に圧延性、溶接性
に障害が生じ、容器が製作しにくくなるものであって、
したがってＣｕの添加量は２〜６％が好ましい。The inner tank 1 and the outer tank 2 themselves may be formed of copper or a copper alloy. When stainless steel is used for the inner tank 1 and the outer tank 2, 2 to 6% of Cu is contained as a stainless steel component. It is preferable to use the added material. The reason is that C
When the added amount of u is 2% or less, the bactericidal action is small and it is not practical. On the other hand, when the Cu addition amount is 6% or more, problems remain in the steelmaking technology, specifically, the rollability and weldability are mainly impaired, which makes it difficult to manufacture the container.
Therefore, the addition amount of Cu is preferably 2 to 6%.
【００１３】ここで、本実施例に基づく電気洗濯機の耐
バクテリヤ・耐細菌実験結果について下記する。Here, the results of the bacterium-resistant and bacterium-resistant experiments of the electric washing machine according to this embodiment will be described below.

ンレス鋼製内槽の外表面壁および合成樹脂製外槽の内表
面壁に、φ２mmのＯＦＣ（純銅）あるいはＰＢ２（青
銅）製細線を、全表面の１０％程度巻き付けた。In the experiment, a commercially available fully automatic washing machine was used, and a fine wire of OFC (pure copper) or PB2 (bronze) having a diameter of 2 mm was completely attached to the outer surface wall of the stainless steel inner tank and the inner surface wall of the synthetic resin outer tank. About 10% of the surface was wound.
【００１５】また、同様に、ステンレス鋼製内槽の外表
面壁に１０μｍ厚の電気Ｃｕめっき膜を、合成樹脂製外
槽の内表面壁に２μｍ厚の無電解Ｃｕめっき膜を付着さ
せた。Similarly, a 10 μm thick electric Cu plating film was attached to the outer surface wall of the stainless steel inner tank, and a 2 μm thick electroless Cu plating film was attached to the inner surface wall of the synthetic resin outer tank.
【００１６】そして、このようにして組み立てた試作品

クテリヤや細菌類の付着に伴う黒色の“ぬめり”が全体
的に極く少なく、銅材の表面にはほとんど“ぬめり”の
付着が認められなかった。As a result, in this prototype, the black "slickness" caused by the adhesion of bacteria and bacteria is entirely present on the inner surface wall of the outer tank and the outer surface wall of the inner tank facing the closed space between the outer tank and the inner tank. Very little, and almost no "stickiness" was found on the surface of the copper material.
【００１８】一方、従来製品の場合は、前記閉空間に臨

【００１９】なお、実験例では、銅および銅合金として
それぞれＯＦＣ（純銅）あるいはＰＢ２（青銅）を用い
て効果を確認したが、その他の材料、例えば黄銅あるい
はこれらに準ずる材料を使用することができる。In the experimental example, OFC (pure copper) or PB2 (bronze) was used as the copper and the copper alloy, respectively, but the effect was confirmed, but other materials, for example, brass or a material similar thereto can be used. .
【００２０】また、Ｃｕ部材の容器表面壁への取付面積
率は多いほど好ましいと思われるものの、先の実験例で
は１０％程度でも効果があったので、５〜３０％が実用
的と思われる。Further, it is considered that the larger the mounting area ratio of the Cu member to the surface wall of the container is, the more preferable it is. However, in the above experimental example, about 10% was effective, so 5 to 30% seems to be practical. .
【００２１】さらに、強い遠心力に耐えるためには、青
銅やＺｒ系、Ｂｅ系、Ｍｇ系の銅合金など、高強度材の
使用が望ましい。Further, in order to withstand a strong centrifugal force, it is desirable to use a high-strength material such as bronze, Zr-based, Be-based or Mg-based copper alloy.

It is preferable to promote the supply of u positive ions, that is, the corrosion dissolution of copper. For this purpose, it is effective to give an electrochemical interaction with a material having a corrosion potential nobler than that of copper. Specifically, for example, a copper material is attached while maintaining electrical contact with stainless steel.

In an electric washing machine with a structure in which the inner tub is attached to the inside of the outer tub, a closed space is created between the inner surface wall of the outer tub and the outer surface wall of the inner tub, which is an environment in which bacteria and bacteria can easily propagate. Also, as a means for suppressing the contamination of laundry by these bacteria and bacteria, the inner tub of the washing machine is detachable from the outer tub, which will be described with reference to FIG. Then, the pulsator 4 and the screw therebelow can be freely removed, and by extension, the inner tank 1 can be freely removed from the outer tank 2.

殖を最小限に止どめることができる。That is, according to this structure, since the closed space between the inner surface wall 2a of the outer tank 2 and the outer surface wall 1b of the inner tank 1 can be put into the closed space, it goes without saying that the inner surface wall 2a of the outer tank 2 is of course required. In particular, the outer surface wall 1b of the inner tank 1 taken out can be regularly cleaned and maintained, and the attachment and reproduction of bacteria and bacteria can be minimized.

Therefore, it is possible to continue the effect of preventing adhesion and reproduction of bacteria and bacteria for many years.
