Below, the action of the electric driving device of above-mentioned formation is described.In addition, this electric driving device is described by the action of setting as being used for rinsing maching draining valve (not shown) switching occasion.
Draining valve is in when cutting out, as shown in Figure 4, drives load and be in the state farthest that stretches out from device with output link 15.Thus as shown in Figure 4 drive load with output link 15 above effectively F often work, make draining valve closed tightly.At this moment, the triadic relation of first clutch unit 6b and motor pinion 7 that becomes the second clutch unit and clutch operating member 8 is promptly shown in Fig. 7 (A).Be exactly that clutch operating member 8 separates with motor pinion 7, and first clutch unit 6b and motor pinion 7 are disengaged because solenoid 9 disconnects.
Then, open draining valve and switch on, make the 6 rotating whiles of rotor, switch on, make solenoid 9 to connect to electromagnet 9b to motor 5 when needs.So, shown in Fig. 7 (B), make clutch operating member 8 close to motor pinion 7, the middle pressing face 8c of its cam surface is contacted with motor pinion 7.Thereafter, shown in Fig. 7 (C), the pressing face 8c of clutch operating member 8 overcomes the elastic force of helical spring 18 motor pinion 7 is further pushed downwards, and first clutch unit 6b is engaged with motor pinion 7.At this moment, the revolution of rotor 6 is slowed down successively reach motor pinion 7, first order gear 10, second level gear 11, third level gear 12, output gear 13 and output pinion 14.In view of the above, make with the driving load of output pinion 14 engagement and overcome the elastic force of not shown spring of the elastic force F of its not shown spring and pressing member 20 with output link 15 slowly in the access to plant.Therefore draining valve is slowly opened.In addition, shift to Fig. 7 (C) from Fig. 7 (A), connection because of solenoid 9, the instantaneous mobile and instantaneous of movable core 9a carries out, yet, at that time, the junction surface 6c of first clutch unit 6b and the coupling/decoupling 7a of motor pinion 7 are collided, connect even often produce solenoid 9, and the situation that movable core 9a also is failure to actuate.But if even owing in such occasion, must make the situation separately of colliding of both 6c, 7a in returning of rotor 6 circled, at least through rotor 6 revolution week ages, and become Fig. 7 (c) state, promptly clutch is in the state of combination.
Because when driving load with output link 15 slowly in the access to plant time, output gear 13 turns round along the clockwise direction among Fig. 3 (A), the cam projection 8i of clutch operating member 8 is slowly moved in the stria 13e of cam path 13d go.And, when cam projection 8i comes position shown in the middle double dot dash line of Fig. 3 (B), promptly make drive load and soon be inhaled in the device fully with output link 15 before, make the pushes protrusion 13h of output gear 13 begin to push the second arm 8j of clutch operating member 8.With this pushing 8 beginnings of clutch operating member are turned round along the counter clockwise direction among Fig. 3 (B).One advances, effect because of the elastic force and the inclined-plane 8d of helical spring 18, make clutch operating member 8 and then instantaneous in the counterclockwise direction revolution, make motor pinion 7 instantaneous to bottom surfaces 8e in-migration from following pressure surface 8c, make motor pinion 7 become Fig. 7 (D) state with the engaging instantaneous being disengaged of first clutch unit 6b through inclined-plane 8d with the contact position of clutch operating member 8.At this moment, drive load, make the relation of output gear 13 and clutch operating member 8 become Fig. 3 (B) state with in the output link 15 complete accesss to plant.Utilize this instantaneous operation can prevent from slowly to throw off the unfavorable condition that produces, for example can prevent the wearing and tearing of coupling/decoupling 7a of the junction surface 6c of rotor 6 or motor pinion 7 or damaged etc. because of clutch.
And at state shown in Fig. 7 (D), solenoid 9 is still connected, yet, because of motor pinion 7 separates with first clutch unit 6b, make the turning power of rotor 6 can not reach driving load output link 15.In addition, at that time, rotor 6 continues revolution.In addition, drive load with on the output link 15, move thereby make the driving load promptly close the draining valve direction to its origin-location with output link 15 because the elastic force F of spring often acts on.But, thereby make motor pinion 7 stop revolution owing to the prevention rotating part 8b of clutch operating member 8 engages with the projection 7c of motor pinion 7.Therefore, make by gear train therewith the drivings load that links to each other of motor pinion 7 be prevented from the mobile of output link 15, and be maintained at state shown in Figure 5.Its result remains on open mode with draining valve, and draining is continued.
Next, after finishing draining, action describes when closing draining valve.At first, solenoid 9 is disconnected.So clutch operating member 8 is separated with motor pinion 7.In view of the above, shown in Fig. 7 (E), the prevention rotating part 8b of clutch operating member 8 and the projection 7c of motor pinion 7 are disengaged, and motor pinion 7 can be turned round.Its result makes the driving load that links to each other with motor pinion 7 by gear train begin to the origin-location because of spring force with output link 15, promptly closes the draining valve direction and moves.This is driven load be passed to output pinion 14, output gear 13, third level gear 12, second level gear 11 and first order gear 10 successively to the reset movement of its original position with output link 15.At this moment, make the gear train that is connected to first order gear 10 from output gear 13 become the speed increasing gear group, first order gear 10 and be integral rotating rubber system speed regulator 16 along clockwise direction high speed rotary among Fig. 4 and Fig. 5 with first order gear 10.So, because of centrifugal force outwards moves, bring into play braking function with cylindrical wall 1c sliding contact by its arm 16a.Therefore, become to make and drive load and slowly carry out with the reseting movement to original position of output link 15.In addition, make when the energising of motor 5 makes solenoid 9 outages and interrupt, yet, also can not make interruption, and be used for the driving of other load.
