Abstract

A washing machine is disclosed, in which a rotary power of a driving unit is stably provided to a pulsator or a washing tub in a short time. The washing machine includes a motor having a stator (7a) and a rotor (7b); a spin shaft (5) of a hollow, an upper end of the spin shaft is fastetned to a washing tub (2); a washing shaft (4) of which an upper end is fastened to a pulsator (3) inside of the washing tub; sliders (31) and (35) moving up and down along an outer circumference surface of the spin shaft to selective transmit a rotary power of the rotor to the spin shaft; an actuator (6) for inducing the up and down movement of the slider; a power transmission means between the actuator and the slider for converting a power transmittance path of the actuator and transmitting to the slider; and an attenuating means between the actuator and the slider for delaying a power generated from the actuator and then transmitting to the slider.

Dependent claims

A washing machine comprising:

a motor having a stator, and a rotor rotatable by a current induced from the stator;
a hollow spinning shaft having an upper end coupled with a washing tub;
a washing shaft rotatably fitted in a hollow part of the spinning shaft, having an upper end coupled with a pulsator fitted in the washing tub;
a connector assembly fitted between the rotor and the washing shaft for transmission of a rotating force from the rotor to the washing shaft;
a slider fitted to be movable in up and down directions along an outside surface of the spinning shaft for selective transmission of the rotating force from the rotor to the spinning shaft;
an actuator for causing the up and down movement of the slider;
a rotational movement link;
a vertical movement member coupled with the rotational movement link, wherein the rotational movement link and the vertical movement member are disposed between the actuator and the slider for converting and transmitting power from the actuator to the slider;
and
a means between the actuator and the slider for absorbing power transmitted from the actuator to the slider, wherein the means includes a spring.
