Because the wheel hub 160 of brake assemblies 700 constraint dehydrating shafts 100, so planetary gear 220 is toward the opposite direction rotation of the central gear 242 of bottom dehydrating shafts 240 time, with direction wheel hub 160 around the revolution identical with central gear 242.As mentioned above, along with the revolution of planetary gear 242, the upper wash axle 210 that is connected with coupling piece 230 is in the 120 inner rotations of top dehydrating shaft.
In addition, during dehydration, the opposite direction rotation of clutch operating motor 620 to the time with washing, and clutch lever 640 is kept vertical state.The 640b of shaft coupling support sector is connected in (the 1st position) bottom dehydrating shaft 240 and rotor axle bush 534a simultaneously in order to make slip coupling 650, and moves to the bottom.That is, the protuberance 652 of slip coupling 650 breaks away from from the connecting hole 664 of brake 660, and slip coupling 650 is owing to deadweight is moved to the bottom.At this moment, revolving force passes on process as follows: the revolving force of rotor assembly 500 is conveyed to the rotor axle bush 534a of rotor rack 530, lower wash axle 240, planetary gear 220, upper wash axle 210.Then, slip coupling 650 is meshing rotor axle bush 534a and bottom dehydrating shaft 140 simultaneously, thereby the revolving force of rotor axle bush 534a is conveyed to bottom dehydrating shaft 140 and wheel hub 160 and top dehydrating shaft 120.Promptly owing to the driving of motor, wash shaft 200 and dehydrating shaft 100 will rotate simultaneously with same speed, and dewater.
Because the wheel hub 160 of dehydrating shaft 100 and bottom dehydrating shaft 240 be with same speed rotation, planetary gear 220 not rotations, but still together revolve round the sun with central gear 242 identical direction and wheel hubs 160.
