Abstract

A washing machine having a device for directly reducing vibration of an external structure serving as a direct factor for causing a user to feel vibration. The washing machine includes an external structure forming an external casing; a washing tub installed in the external structure; a driving device for driving the washing tub; a support device for supporting the washing tub; and dynamic vibration absorbers for directly reducing vibration transmitted to the external structure.

Claims

1. A washing machine comprising:

an external structure forming an external casing;

a washing tub installed in the external structure;

a driving device for driving the washing tub;

a support device for supporting the washing tub; and

at least one dynamic vibration absorber for directly reducing vibration transmitted to the external structure.

2. The washing machine as set forth in claim 1,

wherein the at least one dynamic vibration absorber is installed directly on the external structure.

3. The washing machine as set forth in claim 2,

wherein the at least one dynamic vibration absorber comprises a plurality of dynamic vibration absorbers, with at least one of the dynamic vibration absorbers being installed at at least one position on the external structure.

4. The washing machine as set forth in claim 3,

wherein the dynamic vibration absorbers are installed at one of an upper portion and a side portion of an inside of the external structure.

5. The washing machine as set forth in claim 1, wherein the at least one dynamic vibration absorber includes:

a vibrating poise having a weight;

an elastic member having an elastic restoring member; and

a damping member for reducing vibration.

6. The washing machine as set forth in claim 1, wherein the support device includes:

suspension springs for elastically supporting the washing tub; and

dampers for reducing vibration of the washing tub.
