Abstract
A washing machine having a driving motor provided with a stator unit, which is formed in a shape of a ring, having a rotator unit disposed at an inner side thereof and a bearing housing configured to install the driving motor, the bearing housing fixed at a rear surface of the water tub through an insert injection molding, thereby able to maintain a stable state of being installed at the water tub.
Claims17
A washing machine, comprising:
- a body;
- a water tub installed inside the body to contain water;
- a rotating tub rotatably installed inside the water tub;
- a driving motor configured to generate a rotating force to rotate the rotating tub;
- and
- a bearing housing formed through an insert molding at a rear surface of the water tub and provided with the driving motor installed therein,
- wherein the driving motor includes a stator unit formed in a shape of a ring, a rotator unit disposed at an inner side of the stator unit to rotate while interacting with the stator unit, and a rotating shaft having one end thereof connected to the rotating tub while the other end thereof connected to a center of the rotator unit, and
- wherein the bearing housing comprises a housing part formed in a shape of a ring and provided with a bearing installed at an inner circumferential surface thereof so as to rotatably support the rotating shaft, a flange part extended from the housing part radially and outwardly and provided with the driving motor fixed thereto, and a plurality of fastening parts integrally extended from a periphery of the flange part to a rear side of the flange part and provided with the stator unit fastened thereto while being spaced apart from each other in the circumferential direction.
