    Vibration Reduction Device for Washing Machine
    The present invention relates to a device for reducing the dehydration vibration of the washing machine, and more particularly, to a vibration reducing device of the washing machine for efficiently absorbing the vibration noise generated by the unbalance due to the uneven distribution of the laundry during centrifugal dehydration.
    1 and 2 schematically show a structure of a pulsator washing machine which is generally used, and a motor 2 is fixedly installed at a lower side of the washing machine case 1, and the center of the case 1 is fixed. A clutch 3 connected to the motor 2 is mounted at the lower end of the shaft, and a washing tank (outer tank) 4 and a dehydration tank (inner tank; 5) are provided in multiple layers on the central shaft of the clutch 1, and the dewatering tank is installed. A pulsator 6 is coupled to the central axis of the inner bottom portion of the 4, and a damper 7 supporting the washing tank 4 from all sides is symmetrically fixed to the outer periphery of the lower end of the washing tank 4. Each damper 7 has a structure in which a snubber bar 8 that absorbs vibration by friction is coupled. Here, reference numeral 9 denotes a water supply valve, and 10 denotes a water level sensor.
    In the conventional washing machine, when the laundry is balanced during dehydration, the washing tank (4) and the dehydration tank (5) rotate smoothly without eccentricity, but when the laundry is unbalanced, the centrifugal dehydration process The centrifugal force acts toward this ubiquitous side, and the washing tank 4 and the dehydration tank 5 are shaken severely.
    In order to alleviate the vibration caused by such eccentricity, as described above, the washing tank 4 is supported by the damper 7 and the snubber bar 8 so that the impact generated in the washing tank 4 and the dewatering tank 5 is reduced. It was to reduce the noise and vibration by not being transmitted to the case (1).
    On the other hand, as another vibration reduction device according to the prior art as shown in Figure 3, a spring or hydraulic / pneumatic damper for absorbing vibration between the four corners in the washing machine case 1 and the upper outer periphery of the washing tank (4) (7a) was installed.
    However, in the structure in which the damper 7 and the snubber bar 8 shown in FIG. 2 are installed among the vibration reduction devices of the conventional washing machine as described above, the damper 7 supports only the lower end of the washing tank 4. Therefore, there was a problem in that the vibration is not exhibited against the vibration generated in the upper portion of the washing tank 4, and to compensate for this, the spring or hydraulic / pneumatic damper (7a) shown in Figure 3, the upper portion of the washing tank (4) In the structure installed in the above, not only the noise is generated in the suction means itself, but also installed only in a limited position, there is a new problem that it is difficult to smoothly absorb vibration in other parts.
    Accordingly, the present invention has been made to solve the above problems, to improve the vibration noise of the vibration noise generated due to the unbalance of the laundry during centrifugal dehydration, and to stably absorb any part of the centrifugal force acting It is an object of the present invention to provide a vibration reducing device of a washing machine that can be made.

    2 is a plan view of the conventional washing machine shown in FIG.

    Vibration reducing device of the washing machine according to the present invention for achieving the above object is a case side frame in close contact with the inner surface of the washing machine case, the washing tank side frame in close contact with the outer peripheral surface of the washing tank provided in the case, and the two frames It is composed of an elastic absorbing plate that is filled between the elastic support plate between the frames, in particular, the elastic absorbing plate is characterized in that the synthetic rubber material with high elastic restoring force.
    Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
    As shown in Figure 4 and 5, the vibration reducing device (D) of the washing machine according to the present invention is a band-shaped case side frame 11 in close contact with the inner surface of the washing machine case (1), and the case (1) ) And a band-shaped washing tank side frame 12 in close contact with the outer circumferential surface of the washing tank 4 provided in the inner plate, and the two frames 11 and 12 in the form of a plate and elasticity between these frames 11 and 12. It consists of an elastic absorbing plate 13 to support, the elastic absorbing plate 13 is made of a synthetic rubber material with excellent elastic restoring force.
    Vibration reducing device (D) according to the present invention can be applied to a conventional washing machine. That is, as shown in FIG. 1, the washing machine 2 is fixedly installed at one lower side of the outer case 1, and a clutch connected to the motor 2 is disposed at the lower end of the central axis of the case 1. (3) is mounted, and the washing tank 4 and the dehydration tank 5 are provided in multiple layers on the central axis of this clutch 1, and the pulsator 6 is installed in the inner bottom part of the dehydration tank 4 at the said center. Coupled on the shaft, the damper 7 supporting the washing tank 4 from all sides is symmetrically fixed to the outer periphery of the lower end of the washing tank 4, and each damper 7 absorbs vibration by friction. The snubber bar (Snubber Bar; 8) is coupled, the vibration reduction device (D) of the present invention is inserted between the case (1) and the upper portion of the washing tank (4).
    Thus, the lower end of the washing tank 4 is supported by the damper 7, and the upper part is supported by the vibration reduction device D, thereby maintaining a more stable state. That is, as shown in FIG. 6, when the laundry is unbalanced in the dehydration tank 5 and the washing tank 4 is biased toward one side of the case 1 during centrifugal dehydration, the elastic restoring force of the elastic absorbing plate 13 (arrow Direction), the washing tank 4 is quickly returned to the center, whereby the phenomenon that the washing tank 4 hits the case 1 by the centrifugal force can be prevented. At this time, since the restoration state is not even applied to a specific part but is evenly distributed, the washing tank 4 is always returned to the same shape to reduce the vibration while always being returned to the same shape. There is no noise, and thus the overall noise problem can be solved.
    The effects of the present invention that can be expected by the configuration and action as described above are as follows.
    The washing machine according to the present invention has a double support structure in which a lower end of the washing tank 4 is supported by the damper 7 and an upper portion thereof is supported by the vibration reducing device D, so that the entire washing tank 4 is damped. By using elastic rubber without using a spring or hydraulic / pneumatic damper 7a, etc., the noise is not generated, and the entire outer circumferential surface of the washing tank 4 is supported so that it is not vulnerable to vibration. Since the same vibration damping action is made in any part, there is an effect that can realize a good quietness and stable system.
