Abstract

A fabric treating machine according a present invention comprises a first vibration mitigation part which is disposed between a stator and a bearing unit. Therefore, it can reduce the transfer of the vibration from the driving unit to the bearing unit, and the vibration of an inner tub and an outer tub can be reduced, and a noise can be reduced. Thus, a reliability of product can be improved. Also, a fabric treating machine according a present invention comprises a vibration mitigation part which is disposed between an upper bearing unit and a lower bearing unit. Therefore, it can reduce the vibration transfer from the lower bearing unit to the upper bearing unit, and the vibration of an inner tub and an outer tub can be reduced, and a noise can be reduced.

First claim

The invention claimed is:

1. A fabric treating machine comprising:
an outer tub which is configured to contain water;
an inner tub which is disposed in the outer tub and configured to receive fabric therein;
a driving unit which comprises a rotor, a stator and a rotary shaft and generates a rotary power;
a bearing unit in which the rotary shaft is inserted, wherein the bearing unit is fixed to the outer tub; and
a first vibration mitigation part which is made separately from the bearing unit and is disposed between the stator and the bearing unit to reduce a vibration transfer between the stator and the bearing unit,
wherein the first vibration mitigation part comprises:
a plurality of bearing connection portions which are connected to the bearing unit and are disposed separately from each other with prescribed intervals in a circumferential direction on a first plane;
a plurality of stator connection portions which are connected to the stator and are disposed between the bearing connection portions in the circumferential direction on a second plane parallel to the first plane; and
a plurality of connection portions which are disposed in an up and down direction to connect the plurality of bearing connection portions to the plurality of stator connection portions in the circumferential direction,
wherein the bearing connection portions, the connection portions, and the stator connection portions are connected to each other to form a one piece body having a continuous ring shape, and
wherein the one piece body includes only a single gap between a pair of spaced ends such that the one piece body has a continuous ring shape between the pair of spaced ends.

2. The fabric treating machine of claim 1 , wherein the plurality of bearing connection portions are disposed to contact with the bearing unit, and
the plurality of stator connection portions are disposed to contact with the stator by bending from the plurality of bearing connection portions.

3. The fabric treating machine of claim 1 , wherein the connection portions are formed to lean at a prescribed angle towards the bearing connection portions and the stator connection portions.

4. The fabric treating machine of claim 3 , wherein the connection portions are formed perpendicularly to the bearing connection portions or the stator connection portions.

5. The fabric treating machine of claim 1 , wherein at least one of the bearing connection portions and the stator connection portions includes a boss which is projected from one of the bearing connection portions and the stator connection portions to a height of the other of the bearing connection portions and the stator connection portions and is formed for inserting a bolt.

6. The fabric treating machine of claim 1 , wherein the first vibration mitigation part is not made from a same material as the bearing unit.

7. The fabric treating machine of claim 1 , further comprising a second vibration mitigation part which is disposed at the rotor and reduces vibration generated by the rotor, the second vibration mitigation part comprising a disk.

8. The fabric treating machine of claim 1 , wherein the bearing unit comprises:
an upper bearing part into which the rotary shaft is inserted, the upper bearing part being fixedly connected to the outer tub; and
a lower bearing part into which the rotary shaft is inserted, the upper bearing part being connected to the lower bearing part, and
wherein the plurality of bearing connection portions are connected to the lower bearing part.
