Below, the effect of clutch apparatus of the automatic washing machine of said structure is described.
At first, clutch motor 6 is in before the washing beginning does not have the logical closed condition that goes up power supply, and shaft coupling 15 keeps the decline state shown in Fig. 2 b and Fig. 3 b.
At this moment, but mover 9 is positioned at the groove that inclined plane 801 is arranged 800 of lever 8, and shaft coupling 15 is positioned on the declivity point.
This moment is as clutch motor 6 energisings, power supply clutch motor 6 is opened, the driving force of above-mentioned clutch motor 6 is transmitted on the cam 600 by driving shaft, because the connecting rod 17 of the bar connecting axle 601 that the rotatablely moving of above-mentioned cam 600 is connected cam just can move to clutch motor 6, is guided the guiding lever 8 of lever 30 to pull to clutch motor 6 thereupon.
At this moment, the loopback spring 14 of above-mentioned guiding lever 30 rearward end setting prolongs.
On the one hand, but the mover 9 that contacts the inclined plane 801 of above-mentioned lever 8 during cam 600 rotation is tilted face 801 drops, and shown in Fig. 2 a and Fig. 3 a, but mover 9 is positioned at tabular surface 802 bottoms of lever 8 when cam 600 is positioned at support level.
