However, in recent years, in particular,
The remarkable prevalence of fully automatic washing machines has caused problems, especially when using powdered soap. That is, when washing is performed using powdered soap in such a type of washing machine, the adhesion of washing debris, soap debris, mold and the like is observed between the outer washing tub and the inner washing machine of the washing machine. This naturally becomes remarkable as the number of uses increases. When the amount of these deposits increases, the generation of odors, soap scum with black mold, etc. may flow back into the washing tub during washing and rinsing, and these may adhere to the laundry. This phenomenon also occurs with the use of a synthetic detergent, but is particularly remarkable in the case of powdered soap.

On the other hand, in order to remove dirt from the washing tub as described above, a cleaning agent having a chlorine-based bleaching action has conventionally been used. However, since chlorine gas is generated at the time of use, chlorine gas is generated. Care must be taken, and mixing with wastewater will significantly impair water quality. On the other hand, for example,
Japanese Patent No. 11672 discloses a washing machine in which the dewatering tub is detachable, but there is a problem that the operation of attaching and detaching the dehydration tub is not easy. In addition, since the dehydration tub rotates at a high speed during dehydration, it is required to be easily detachable, and at the same time, to have stability at the time of high-speed rotation and strength to withstand rotation. In particular, it is desirable that the space between the inner washing tub and the outer washing tub has a structure that can be easily viewed from the outside only by opening and closing the lid so that the degree of contamination can be confirmed.

A washing pipe 30 is provided outside the dirt remover 15 from the top to the bottom of the washing tub. As shown in FIG. 9, the washing tube 30 is provided along the wall surface of the outer washing tub 2 and has a circular cross section in this embodiment. However, the cross-sectional shape is not limited to this.

Next, how to use the above washing machine will be described. During rinsing or after washing, tap water is continuously supplied from a hose connected to the water supply port 11. Then, washing water is ejected from the injection ports 9a and 9b of the supply pipe 8, and the washing water is poured into the inner side surface of the outer washing tub 2 and the outer side surface of the inner washing tub 3 to form a flow covering the entirety of these surfaces. Flow down. Therefore, dirt adhering to these surfaces is washed away.

When the motor 25 is rotated and the inner washing tub 3 is slowly rotated, the brush 14 rotates in contact with the outer surface of the inner washing tub 3 and brushes the entire outer surface. Is sufficiently removed.
It goes without saying that this is more effective than simply washing away.

Further, at the same time, washing water is poured from the injection port 18 of the washing pipe 30 to the outer surface of the inner washing tub 3, and dirt is washed out and removed. The washing water spouts vigorously from the small jet port 18 due to the water pressure, but this jet becomes higher and stronger as it goes toward the bottom surface side. This is advantageous because the bottom surface 3a of the inner washing tub is more easily soiled than the upper portion thereof.
