Motion for guide wire 70 curves
Shape also is fixed on metal wire guide 60 on the bear box 10.Therefore, the metal wire that inserts in this metal wire guide 60 is moved by this metal wire guide guiding.Between end of metal wire 70 and actuator 6, connecting rod 50 is arranged.When actuator 6 provides power, connecting rod 50 these metal wires 70 of pulling.
The end 111 of connecting rod 110 of rotatablely moving rotatably is connected with the steady pin 17 that is fixed in carriage 15 1 sides, and the other end 113 contacts with movable slider 35.In order to be transformed into rotatablely moving of movable connecting rod 110 by moving up and down of vertical motion parts 80, there is inclined surface the upper end 81 of vertical motion parts 80.Simultaneously, the body of the connecting rod 110 that rotatablely moves has inclined surface, contacts the 81-face in upper end of this inclined surface and vertical motion parts 80.Therefore, when vertical motion parts 80 move upward by metal wire 70, move along the body of the connecting rod 110 that rotatablely moves in the upper end 81 of vertical motion parts.Therefore, the rotation connecting rod 110 that rotates around steady pin 17 in the counterclockwise direction makes movable slider 35 move upward.
Also have torsionspring 120, be used for when actuator 6 cuts out the help connecting rod 110 that rotatablely moves and return.Insert on the outer surface of steady pin 17 at the center of this torsionspring, and an end is fixed on the carriage 15, and the other end is connected with the connecting rod 110 that rotatablely moves.Therefore, when the connecting rod 110 that rotatablely moves rotated in the counterclockwise direction, torsionspring 120 reversed.When eliminating the power of the vertical motion connecting rod 80 that supports the connecting rod 110 that rotatablely moves when closing actuator 6, the torsionspring 120 that returns original state is rotated in a clockwise direction the connecting rod 110 that rotatablely moves.
At this moment, close 6 o'clock the position that moves downward at actuator, be installed in the retainer 115 on the side of carriage 15 in addition, be used for contacting with the connecting rod 110 that rotatablely moves for restraint slider 35.When the connecting rod 110 that rotatablely moves was rotated in a clockwise direction, retainer 115 contacted with the connecting rod that rotatablely moves, the anglec of rotation of connecting rod 110 so that restriction rotatablely moves, thereby the moving downward of restraint slider 35.
On the other hand, when movable slider 35 moves upward and during with 31 engagements of fixing slider, may be free gear 36 and fixed gear 32 not have situation about meshing, promptly the top of the gear teeth of fixed gear 32 and free gear 36 offsets, and this is defined as instantaneous blocking.When instantaneous when blocking the connecting rod 110 that rotatablely moves under the state and continuing to make movable slider 35 to move upward at this, fixed gear 32 becomes more difficult with the normal engaged of free gear 36.In order to address this problem, need moment to postpone power from the transmission of actuator 6 to movable slider 35, the device of carrying out this function is a buffer device.
As buffer device, suggestion buffer spring 90 is installed between connecting rod 50 and the metal wire 70.In normal operation, buffer spring 90 passes to metal wire 70 with the motion of connecting rod 50, and blocks under the state instantaneous, and these buffer spring 90 elongations so that temporarily absorb the motion of connecting rod 50, and pass to metal wire 70.For this reason, the elastic modelling quantity of this buffer spring 90 is greater than the elastic modelling quantity of torsionspring 120.Therefore, in normal operation, because the elastic modelling quantity of buffer spring 90 is greater than torsionspring 120, buffer spring 90 is accepted the motion of connecting rod 50, and passes to metal wire 70 under the situation that is not having distortion.Block under the state instantaneous, since buffer spring 90 elongations and absorption motion, the therefore temporary transient transmission that stops to metal wire 70.Therefore, the moving upward of temporary delay vertical motion parts 80, this moves upward and will make connecting rod 110 rotation counterclockwise that rotatablely moves.

With reference to figure 4A, when closing the power of actuator 6, the power of connecting rod 50 pulling metal wires 70 is eliminated.Therefore, vertical motion connecting rod 80 moves downward by gravity, thereby also eliminates the rotatablely move power of connecting rod 110 of vertical motion parts 80 supportings.
Therefore, rotatablely move connecting rod 110 by torsionspring 120 reset force and rotate around steady pin 17 clockwise directions.The connecting rod 110 that rotatablely moves rotates to an angle, and the connecting rod that rotatablely moves contacts with retainer 115.
Simultaneously, movable slider 35 moves downward along drying axle 5 by gravity, and eliminates as the reset force of the compression spring 40 of the supporting force of the connecting rod 110 that rotatablely moves.Movable slider 35 moves downward, and contacts up to the other end 113 of this movable slider 35 with the connecting rod 110 that rotatablely moves.Therefore, fixed gear 32 and free gear 36 are thrown off fully, as shown in Figure 4.
In this case, movable slider 35 with dry axle 5 and all be connected with internal connector 25.Just, the spline 37 of movable slider all meshes with outer surface that dries axle 5 and second spline 27 of internal connector.
At this moment, the revolving force of rotor 7b not only passes to wash shaft 4 by movable slider 35, also passes to by movable slider 35 and dries axle 5.Therefore, when all rotating, carry out spin cycle when the impeller that is connected with wash shaft 4 and with drying axle 5 washtubs that are connected.
Below, Fig. 5 A and 5B have represented the spin cycle of washing machine of the present invention.
With reference to figure 5A, provide power to actuator, so that carry out wash cycle, movable slider 35 is moved upward by connecting rod 110 supportings that rotatablely move by aforementioned process.In this case, because movable slider 35 is in this movable slider 35 with the state that dries axle 5 rotations, therefore can be the state of free gear 36 and fixed gear 32 engagements, shown in Fig. 5 B.
In this case, although connecting rod 50 continues pulling metal wire 70, when the connecting rod 110 that rotatablely moves stopped by movable slider 35, vertical motion parts 80 no longer moved upward.Therefore, the buffer spring 90 that is extended by the power of connecting rod 50 temporarily absorbs the power of connecting rods, thereby can temporarily eliminate the power connecting rod 110 that rotatablely moves, that movable slider 35 will be moved upward.
In this case, movable slider 35 is in the state that is connected with internal connector 25.Therefore, when rotor 7b rotates, movable slider 35 is also rotated with rotor 7b, and when movable slider 35 rotations, will occur moment of free gear 36 and fixed gear 32 normal engaged, when the buffer spring 90 pulling metal wires 70 of getting back to original state so that vertical motion parts 80 when moving upward, the result, along with connecting rod 110 rotation counterclockwise that rotatablely moves, movable slider 35 moves upward.This operation is proceeded, and is connected fully with fixed gear 32 up to free gear 36, thereby eliminates this instantaneous blocking.
