Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a bath water absorbing hose and a fully automatic washing machine.

[0002]

2. Description of the Related Art Conventionally, a water absorbent hose made of a synthetic resin such as vinyl chloride and a joint for connecting a main body made of plastic or the like maintain the airtightness of a water absorbent hose connection portion with a fluid adhesive or a filler.

Specifically, as shown in FIG. 3, an adhesive reservoir 28b is provided on the uneven portion of the main body connecting joint 28 so that the water absorbing hose 27 is kept airtight.

The concavo-convex shape of the main body connecting joint 28 is
It is configured to have a single circular arc shape (bamboo shoot shape) or a continuous circular arc shape (screw shape), and to provide the adhesive or filler reservoir 28b on the concave and convex portion.

[0005]

When the water absorbent hose is fixed by providing the adhesive reservoir on the joint for connecting the main body as described above, the water absorbent hose rotates when an excessive force is applied in the clockwise or counterclockwise direction. Therefore, there is a fear that airtightness may not be maintained.

In addition to this, in order to maintain the airtightness by the adhesive, the outer diameter of the hose connection of the joint for connecting the main body requires a tightening margin of the water absorption hose of about 15% or more, so that the workability of hose attachment is poor and There is a problem in that the adhesive may stick out and spoil the appearance.

Further, regarding the shape and hue of the synthetic resin reinforcing material of the water-absorbing hose, there is a problem that stains inside and outside the water-absorbing hose are conspicuous and scratches are caused by the edge of the reinforcing material.
