モーター７の駆動軸に連結する。2. Description of the Related Art In such a stirring type fully automatic one-tub type washing machine, as shown in FIG. 3, for example, an outer tub 4 is suspended and supported in an outer box 1 by a suspension rod 3 having a vibration-proof spring 2 at its tip. Inside the outer tub 4, a washing / dehydrating tub 6 having a stirring blade 5 at the center is rotatably arranged. A motor 7 is arranged below the outer tub 4, and the rotary shaft of the stirring blade 5 and the rotary shaft of the washing / dehydrating tub 6 are connected to the drive shaft of the motor 7.
【０００３】また、外槽４の底部に排水口８を形成し、

６から外槽４を介して排水口８へと排出する。To perform the washing operation, only the stirring blade 5 is rotated to stir the wash water and the clothes in the washing / dehydrating tank 6, and to perform the dewatering operation, the drain valve 9 is opened to perform the washing / discharging operation. After the washing water in the water tank 6 is discharged to the outside of the machine through the drainage port 8 and the drainage pipe 10, the stirring blade 5 and the washing / dehydrating tank 6 are rotated at a high speed, and the water content contained in the clothes is centrifugally applied. Is discharged from the washing / dehydrating tank 6 through the outer tank 4 to the drain port 8.
【０００５】ところで、かかる洗濯運転時の攪拌翼５の

壁の下部に該外槽４の内側に突出する支持部１３を形成
した。By the way, the rotation of the stirring blade 5 during the washing operation, and particularly the vibration due to the high speed rotation of the stirring blade 5 and the washing / dehydrating tank 6 during the dehydration operation are absorbed by the suspension rod 3 provided with the vibration-proof spring 2. However, the suspension bar 3 is attached to the outer tub 4, and conventionally, for example, as shown in FIGS. 4 to 6, a supporting portion 13 that protrudes inward of the outer tub 4 is formed at the lower portion of the side wall of the outer tub 4. Was formed.

積みの妨げになるためである。The support portion 13 has a support portion 13a for accommodating the anti-vibration spring 2 and an accommodating portion 13b for the hanging rod 3 connected to the support portion 13a.
And the support portion 13a and the storage portion 1
3b is a projection of a curved surface and projects into the outer tub 4. here,
The structure in which the support portion 13 projects into the outer tub 4 is that the support portion 13 projects to the outside of the outer tub 4 when the outer tub 4 is stacked at the stage of storage and transportation before completion of the washing machine. Then, this is an obstacle to stacking.

When the support portion 13 of the above is formed to protrude inside the outer tub 4, since the support portion 13 conventionally protrudes like a protrusion as described above, the water contained in the clothes during the dehydration operation is washed and removed. After the water in the outer tub 4 is discharged from the water tub 6 into the outer tub 4, when the water in the outer tub 4 is rotated by the ribs on the bottom surface and the side surfaces of the washing / dehydrating tub 6, the water is absorbed by the support portion 13 protruding into the outer tub 4. Turbulence occurs in the.
【０００８】その結果、水が飛散し、洗濯兼脱水槽６や

Formed in a reduced diameter portion by stepwise bending around the circumference or curved in an arc shape, and forming a support portion of the hanging rod outside the outer tank at the portion of the reduced diameter portion, the support portion being more than the reduced diameter portion. Also, the gist of the present invention is that it is formed so as not to project outward beyond the extension line from the upper part of the outer tub to the lower part of the upper part.

Since the support portion is provided, the support portion does not partially project to the inner side of the outer tank, and even if the support portion is formed on the outer side of the outer tank, the support portion is formed at the position of the reduced diameter portion. Does not project outside the outer tub as the shape of the entire outer tub. Therefore, the outer tanks can be stacked, and turbulent flow does not occur in the water discharged into the outer tank.

での詳細な説明は省略する。Embodiments of the present invention will now be described in detail with reference to the drawings. 1 is a vertical sectional side view of a main part showing an embodiment of an outer tub of a washing machine of the present invention, FIG. 2 is a perspective view of the same, and the entire structure of the washing machine is as already described with reference to FIG. The detailed description of is omitted.
【００１３】本発明の洗濯機の外槽４も防振バネ２と吊
り棒３とで外箱１に吊支されるものであるが、外槽４の
側面下部を２段の折り曲げ部１１ａ，１１ｂにより内側
に下り曲がる段曲げに形成して縮径部１１とした。The outer tub 4 of the washing machine of the present invention is also hung and supported by the outer box 1 by the vibration-proof springs 2 and the hanging rods 3. The lower part of the side surface of the outer tub 4 is bent into two steps 11a, The diameter-reduced portion 11 was formed by forming a step bend that bends inward by 11b.

入用のスリットである。Then, at the position of the reduced diameter portion 11, the outer tank 4
A support portion 12 for the prevention spring 2 and the suspension rod 3 is formed on the outer side of the. The support portion 12 is composed of a support portion 12b of the anti-vibration spring 2 and a storage portion 12c of the suspension rod 3, and the support portion 12b is positioned below the lower bent portion 11b to form an umbrella shape.
The accommodating portion 12c coupled to this is the upper bent portion 11a.
It is formed by the side wall between the lower bent portion 11b and the lower bent portion 11b. In the figure, 12a is a slit for inserting the suspension rod 3 formed in the support portion 12b.
【００１５】この場合、支持部１２は外槽４の外方に突

径部１１であるから、縮径部１１よりも上方部分の外槽
４の上方部４ａから下方への延長線上よりも外方へは突
出しない。よって、外槽４の全体形状としては、外槽４
の外方に支持部１２が突出しない。In this case, the support portion 12 is formed so as to project to the outside of the outer tub 4, but since the support portion 12 is formed on the reduced diameter portion 11, the portion above the reduced diameter portion 11 is formed. The outer tub 4 does not protrude outward from the extension line from the upper portion 4a to the lower portion. Therefore, the overall shape of the outer tank 4 is
The support portion 12 does not project to the outside.
【００１６】また、縮径部１１は外槽４の下方で全周に
渡って形成するから、外槽４は下方部分が全体的に縮径
するだけで、部分的に突出部が形成されることはない。
よって、支持部１２の形成により、外槽４の外方にも内
方にも突出部分が生じることがない。Further, since the diameter-reduced portion 11 is formed over the entire circumference below the outer tub 4, the outer tub 4 is only partially reduced in diameter at the lower portion, and a protruding portion is partially formed. There is no such thing.
Therefore, due to the formation of the support portion 12, no protruding portion is formed outside or inside the outer tub 4.
【００１７】これにより、脱水運転時に洗濯兼脱水槽６
から外槽４に排出された水に外槽４内で乱流が発生する
ことがなく、水の飛散もない。As a result, the washing / dehydrating tank 6 is operated during the dehydration operation.
Turbulent flow does not occur in the water discharged from the outer tub 4 to the outer tub 4, and the water is not scattered.
【００１８】なお、前記第１実施例は縮径部１１を段曲
げにより形成したが、これに限定されるものではなく、
全体を内側に彎曲する円弧状の彎曲部により形成するこ
ともできる。この場合の作用も第１実施例と同様であ
る。Although the diameter-reduced portion 11 is formed by stepwise bending in the first embodiment, the invention is not limited to this.
It can also be formed by an arcuate curved portion that bends the whole inward. The operation in this case is similar to that of the first embodiment.

飛散水による騒音発生も防止できる。また、支持部は外
槽の外方にも突出しないから、外槽を保管や運搬時に段
積みでき保管スペースが少なくてすみ、運搬の作業性も
よいものである。As described above, in the outer tub of the washing machine of the present invention, when the support portion for the vibration-proof spring and the hanging rod is formed on the outer tub, the support portion does not partially project inside the outer tub. Therefore, turbulence does not occur in the discharged water in this part, and it can be drained smoothly,
Noise generation due to splashed water can also be prevented. In addition, since the support portion does not project to the outside of the outer tank, the outer tanks can be stacked at the time of storage and transportation, the storage space is small, and the workability of transportation is good.
