Problems solved by technology

In this case, the vibration generated from the drive motor is transmitted to the bearing housing side via the clutch stopper, causing a problem of large noise.
[0013] Second, in the prior art, there is no structure for keeping the operation amount (rotation amount) of the clutch lever constant
Therefore, the operation amount of the clutch lever cannot be kept constant, resulting in severe friction between the counterparts (eg, couplings) in contact with the clutch lever, and thus, there is a problem of component wear
[0014] Third, the fastening force of the fastening member for fixing the stator is gradually weakened due to the vibration generated by the high-speed operation of the motor
When the fastening force of the fastening member is weakened, there is a problem that abnormal noise increases due to component eccentricity

Abstract

The present invention provides a washing machine, which includes: a bearing cover arranged on the bottom surface of the outer tub; a clutch stopper arranged on the bottom surface of the bearing cover; and a driving motor connected to the lower side of the clutch stopper Composed of stator and rotor. The clutch stopper includes: a base portion disposed on a bottom surface of the bearing cover; and a fastening boss extending downward by a predetermined length from the base portion and fastened to the stator by a fastening member.

Description

technical field [0001] The present invention relates to washing machines. Background technique [0002] Generally, a washing machine includes a washing tub for holding washing water, a drum rotatably arranged in the washing tub and used for accommodating clothes, etc. and dehydration. [0003] Washing machines can be divided into top loading type in which the center of rotation of the drum is formed vertically and the laundry can be put in from the upper side; The direction of the washing machine is formed obliquely, and the laundry can be loaded from the front in the front loading type (front loading type). [0004] The top loading washing machine can be roughly classified into an agitator type which performs washing by rotating a washing rod protruding from the center of a drum, and a pulsator type. A type washing machine performs washing by rotating a disc-shaped pulsator or drum formed at the lower part of the drum. [0005] The front loading type washing machine is ...
