DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a washing machine.

[0002]

2. Description of the Related Art In a fully automatic washing machine disclosed in Japanese Patent Application No. 5-170556, a washing and dewatering tub comprises a cylindrical body, a bottom plate connected to a lower end of the body, and the above-mentioned body. And a balance ring connected to the upper end of the cover. The body is formed by bending a stainless steel plate into a cylindrical shape and by caulking seams. However, in this case, the seam formed by the caulking connection of the body portion has a poor appearance.

[0003]

[SUMMARY OF THE INVENTION The present invention, is apparent at the joint of the body of the washing and dewatering tank made of stainless steel plate
An object of the present invention is to provide a washing machine capable of suppressing the deterioration .

[0004]

SUMMARY OF THE INVENTION The present invention relates to a body formed by bending a single stainless steel plate into a cylindrical shape and joining seams, and a body connected to a lower end of the body. a bottom plate that is, from a combined compensation rings to the upper end of the body portion, is disposed in the outer tub and rotating blades bottom
In a washing machine having a washing and dewatering tub rotatably provided therein, a resin circulation forming a circulation path for raising and circulating water based on a pumping action of the rotating blades at the bottom of the washing and dewatering tub. A road body is mounted on the inner wall surface of the washing and dewatering tub so as to cover the seam.

[0005] The seam of the body is covered with a resin circulation path which forms a circulation path for circulating water in the washing and dewatering tub, and has a good appearance.

[0006]

FIG. 1 shows the entire structure of a fully automatic washing machine according to an embodiment of the present invention. An outer tub 2 is suspended and supported in the main body 1 of the washing machine, and a washing and dewatering tub 3 is rotatably supported in the outer tub 2.
Are rotatably supported. A motor 5 and a driving force transmitting unit 6 are mounted on the outer bottom surface of the outer tub 2. The motor 5 rotates only the rotary blade 4 via the transmission unit 6 during washing, and rotates the rotary blade 4 and the washing and dewatering tub 3 at high speed during spin-drying.

The washing and dewatering tub 3 includes a body 7, a bottom plate 8, and a balance ring 9 for maintaining the balance of the washing and dewatering tub 3 during high-speed rotation.

Referring to FIGS. 2 to 4 as well, the body 7 is formed by bending a single stainless steel plate into a cylindrical shape and joining seams 10 by goby folding and caulking.
Is formed. The bottom plate 8 is made of a stainless steel plate and is caulked to the lower end of the body 7. The balance ring 9 is made of resin, and is connected to the upper end of the body 7 by a plurality of screws.

Further, the body 7 has a first protruding portion 11 protruding into the washing and dewatering tub 3 on the upper half and a second protruding portion 12 protruding out of the washing and dehydrating tub 3 on the lower half. Each is integrally formed so as to be substantially equally spaced in the lateral direction. These protrusions 11 and 12 work together with the rotary wing 4 to stir the laundry. The body 7 has a large number of holes 13 for draining water during dehydration.

A resin circulating path body 15 that forms a circulating path 14 for circulating water based on a pumping action when the rotary blade 4 is driven is mounted on the inner wall surface of the washing and dewatering tub 3. In this case, the circulation path body 15 is connected to the seam 10.
And the laundry does not hit the seam 10 and is not damaged. A lint filter (not shown) is mounted on the upper end of the circulating path body 15, and the lint is removed when water rising through the circulating path 14 by circulation passes through the filter.

[0011]

According to the present invention, since the joint of the body of the washing and dewatering tub made of stainless steel plate is covered by using the resin circulation path body forming the water circulation path, the structure is complicated. And the appearance can be improved.
