In FIG. 1, reference numeral 10 is a washing / dehydrating tank that also serves as a washing tank, and an agitating blade 11 is provided at the inner bottom portion thereof. An outer tub 12 is provided outside the washing / dehydrating tub, and serves to receive water during dehydration. A driving motor 13 is attached to the lower surface of the outer tub 12 and drives the stirring blade 11 and the washing / dehydrating tub 10 via a speed reducer 15 connected by a belt 14. 16
Is a main body that encloses the washing and dewatering tub 10, the outer tub 12, the motor 13 and the like, and the outer tub 12 is supported by this main body 16 by a support rod 17 so as to be vibration-proof. That is, the sphere 18 is fixed to the upper end of the support rod 17, and the support receiving portion 23 of the outer tub 12 is movably mounted on the sphere 18. A slidable support ball 19 is inserted in the support rod 17, and a coil spring 20 also inserted in the support rod 17 is held between the ball body 18 and the coil spring 20. A weight 22 is fixed to the lower end of the support rod 17. The support ball 19 is mounted on the support portion 21 of the main body 16 so as to be freely movable. The above-mentioned support portion 21, support rod 1
As shown in FIG. 2, 7 are installed at four corners, and the outer tub 12 is supported by the main body 16 in a vibration-proof manner.

When laundry such as clothes is put in the washing / dehydrating tub 10 and the washing machine is driven, and when the washing process is finished and the dehydration process is started, the laundry such as clothes is not evenly distributed in the washing / dehydrating tub. When 10 rotates for centrifugal dehydration, a rotational imbalance occurs and the washing tub 10 and the outer tub 12 are swung largely. At this time, since it is possible to freely move between the outer tub 12 and the sphere 18, and between the support ball 19 and the support portion 21, that is, an inverted pendulum with the support ball 19 as a fulcrum, and
Since the weight 22 is fixed to the lower end of the support rod 17, a pendulum support system that is stable and has a low resonance point is formed.
The lateral vibration of is isolated from the main body 16. Regarding the vibration in the vertical direction, the coil spring 20 is held between the sphere 18 and the support sphere 19, and the support rod 17 is slidable with respect to the support sphere 19, so that the main body 16 is also vibration-proofed. Even when passing through the resonance point of each anti-vibration support system, between the ball 18 and the outer tank 12, the support ball
Since there is appropriate friction between the support portion 21 of 19 and the support ball 19 and the support rod 17, the vibration is attenuated and the outer tank 12 is prevented from coming into contact with the main body 16. Next, a case will be described in which the automatic washing machine is installed so as to be inclined under the influence of the floor surface or the like. As shown in FIG. 3, even if the distance between the support portion 21 and the support receiving portion 23, that is, the contact point between the sphere 18 and the outer tub 12 is made sufficiently small, the weight
Since the resonance point can be made sufficiently low by the action of 22, the outer tank 12 is slightly offset even if the main body 16 is supported while being inclined.
発明の効果 上述したように、従来の吊り下げ方式の支持では防振効
果を良くするために共振点を低くすると、本体と外槽の
支持距離が長くなり、傾斜設置された時の外槽の片寄り
が大きくなる。これに対し、本発明では、重りの作用で
安定した倒立振り子支持が構成できるため、共振点を充
分低くし、しかも、本体と外槽の支持距離を小さくでき
るため、防振効果のすぐれた、しかも傾斜設置されても
外槽が殆んど片寄らない自動洗濯機が実現できる。As described above, in the conventional suspension type support, if the resonance point is lowered to improve the vibration isolation effect, the support distance between the main body and the outer tank becomes long, and the outer tank when tilted is installed. The deviation becomes larger. On the other hand, in the present invention, since the stable inverted pendulum support can be configured by the action of the weight, the resonance point can be sufficiently lowered, and further, the supporting distance between the main body and the outer tub can be reduced, so that the vibration damping effect is excellent, Moreover, it is possible to realize an automatic washing machine in which the outer tub is hardly offset even if it is installed on a slant.
