For example, when the rotation of motor shaft 11a inhour, drive the 20 inhour rotations of first central gear, 19 of first planetary gears turn clockwise, because first planetary gear 19 can not revolve round the sun, drive the first outer planet tooth 15a thus and also turn clockwise, dehydration barrel axis 13 is done under the drive of the first outer planet tooth 15a and is turned clockwise.
The rotation of motor shaft 11a drives the 17 inhour rotations of second central gear simultaneously, second planetary gear 16 turns clockwise with first planetary gear, 19 the same also doing, but because second planetary gear 16 can carry out counterclockwise revolution around second central gear 17, make its second planet toothholder 22 carry out counter rotation thus, impeller axle 14 carries out the inhour rotation under second Planetary gear seat 22 drives.
This shows that the rotation direction of impeller axle 14 and dehydration barrel axis 13 is opposite, that is to say impeller axle (little axle) when 14 anti-(inhours) are changeed, dehydration barrel axis (macro-axis) 13 is just (clockwise) commentaries on classics just; In like manner, when impeller axle (little axle) 14 when just (clockwise) changeing, dehydration barrel axis (macro-axis) 13 just anti-(inhour) commentaries on classics to form powerful anti-stranding current, by the intermittently power-on of controller, reaches desirable clean result.
