Middle rotating member 99 has through hole at central part, has surrounding wall portion 105 at peripheral part.Internal-gear 98 has substantially been formed in the inner circumferential of surrounding wall portion 105.In addition, the front end of input side rotating member 97 has been inserted in the through hole of middle rotating member 99, and sun gear 96 is outstanding to the inner side of surrounding wall portion 105.
Outlet side rotating member 101, the multiple fulcrums 109 that there is plectane portion 107, the outlet side small gear 108 highlighted upward from plectane portion 107 and be provided with downwards from plectane portion 107.The plectane portion 107 of outlet side rotating member 101, by embedding in middle rotating member 99, be assembled on middle rotating member 99, planetary pinion 100 has been rotatably installed on fulcrum 109.
As shown in Fig. 1, Fig. 9, in first and second middle solid of rotation 81,82 intert share pin 112 (fulcrum), the first middle solid of rotation 81 and the second middle solid of rotation 82 mutually rotatable centered by pin 112 respectively.First middle solid of rotation 81, is the gear at peripheral part with teeth portion, engages with the input side small gear 103 of motor pinion 22 and input side rotating member 97.Thus, motor pinion 22 and input side rotating member 97 link through the first middle solid of rotation 81.
Second middle solid of rotation 82, has been arranged on the top of the first middle solid of rotation 81, has had intermediate gear 113 and intermediate speed pinion 114.In addition, the intermediate gear 113 of the second middle solid of rotation 82 engages with the outlet side small gear 108 of outlet side rotating member 101, and the intermediate speed pinion 114 of the second middle solid of rotation 82 engages with the locking tooth 91 of stopping lever 79.Thus, stopping lever 79 swings freely with outlet side rotating member 101 in linkage through the second middle solid of rotation 82.
As shown in Figure 2 and Figure 3, in speed governing solid of rotation 83, interted pin 117 (fulcrum).Speed governing solid of rotation 83, rotatably be bearing on pin 117, possess speed governing gear 118, be formed in the speed governing small gear 119 of the below of speed governing gear 118 and be arranged on the pair of sliding body 120 of top of speed governing gear 118, and there is the structure of the brake type of centrifugal clutch structure.
Shell 11 defines cylindrical part 121, and slide mass 120 has been housed in cylindrical part 121.If the rotational speed of speed governing solid of rotation 83 will exceed admissible value, then slide mass 120 is moved to expanding direction by centrifugal force, by the inner peripheral surface sliding contact with cylindrical part 121, speed governing solid of rotation 83 produces braking force.
As shown in Fig. 2, Fig. 5, the speed governing gear 118 of speed governing solid of rotation 83 engages with the small gear 87 of stopping solid of rotation 78, and the speed governing small gear 119 of speed governing solid of rotation 83 engages with the external tooth gear 52 of the housing 48 of planetary gears 29.Thus, the housing 48 of stopping solid of rotation 78 and planetary gears 29 links through speed governing solid of rotation 83.
Below, the effect in said structure is described.
(1) not under the A-stage of motor 13 supply power, steel wire 15 is rolled pulley 12 from steel wire and is sent, drain valve 9 cuts out, under such A-stage, as shown in Figure 9, stopping lever 79 is switched to by the tensile force (loading force) of draft helical spring 93 and stops removing position D, and the first locking pawl 92 of stopping lever 79 departs from from the second locking pawl 88 of stopping solid of rotation 78.
(2) then, if to motor 13 supply power, then rotor 19 rotates to a direction.When the spinning movement of rotor 19, as shown in Figure 4, the skate 70 of cam lever 68 becomes the state of sliding wall 64 sliding contact rolling pulley 12 with steel wire, and downside clutch component 35 is boosted to the top of axis by the side of the opposing party of the circumference in the front end of the operating sheet 71 in cam lever 68 with revolting the restoring force of compression helical spring 36.Thus, as shown in Figure 5, the locking piece 45 of downside clutch component 35 is locking with the locking recess 39 of upside clutch component 34, and clutch mechanism 31 becomes coupled condition.Now, the locking piece 75 of cam lever 68 is not locking with the locking pawl 37 of upside clutch component 34, thus, allows the rotation of upside clutch component 34.
In addition, if rotor 19 rotates to a direction as described above, then motor pinion 22 rotates to a direction, downside clutch component 35 and upside clutch component 34 rotate, the housing 48 of planetary gears 29 rotates, as Fig. 2, shown in Figure 10, through speed governing solid of rotation 83, the stopping direction of arrow of solid of rotation 78 to Figure 10 rotates, and the first middle solid of rotation 81 rotates to other direction (arrow with reference to Figure 10), the input side rotating member 97 of driving mechanism 80 rotates to a direction, link with input side rotating member 97, middle rotating member 99 rotates to other direction E, and outlet side rotating member 101 rotates to a direction F.
Because rotated to a direction F by such outlet side rotating member 101, second middle solid of rotation 82 rotates to other direction E, and the intermediate speed pinion 114 of the second middle solid of rotation 82 also rotates to other direction E, so the tensile force of draft helical spring 93 revolted by stopping lever 79, swing (arrow with reference to Figure 10) from stopping removing position D towards stop position C.
(3) as shown in figure 11, if stopping lever 79 arrives stop position C, then the first locking pawl 92 engages with the second locking pawl 88, the rotation of stopping solid of rotation 78 is prevented from, thus, the rotation of the housing 48 (with reference to Fig. 2) of speed governing solid of rotation 83 (with reference to Fig. 2) and planetary gears 29 is also prevented from.
Now, stopping lever 79 is switched to stop position C, second middle solid of rotation 82 and outlet side rotating member 101 stop, on the other hand, the middle solid of rotation 81 of motor pinion 22, first, input side rotating member 97 and middle rotating member 99 continue to rotate to each direction of arrow indicated by the solid line.Therefore, the second middle solid of rotation 82 and outlet side rotating member 101 act on the loading force G of the direction of arrow be illustrated by the broken lines, thus, stopping lever 79 acts on the loading force G loaded to stop position C by stopping lever 79.
Thus, stopping lever 79 is maintained at stop position C, continue to rotate by motor pinion 22, downside clutch component 35 and upside clutch component 34 rotate, relative to the housing 48 that the rotation in planetary gears 29 is prevented from, sun gear 38 rotates, by the revolution of planetary pinion 53 one side rotation one side, driven member 49 rotates, and output wheel 32 rotates, steel wire is rolled pulley 12 and is rotated to take-up direction H (example of other direction, with reference to Fig. 3) with revolting the loading force of loaded member.Thus, steel wire 15 is rolled pulley 12 by steel wire and is batched, and drain valve 9 is opened, and draining starts.
(4) if drain valve 9 standard-sized sheet, then as shown in Figure 6, the skate 70 of cam lever 68 is rolled pulley 12 projection 65 by steel wire rolls sense of rotation (take-up direction H) pushing of pulley 12 to steel wire, cam lever 68 rotates around fulcrum 69.Thus, the side of one side of the circumference in the front end of the operating sheet 71 of cam lever 68 abuts with downside hub portion 43 (with reference to Fig. 5), its result, with revolting the loading force of compression helical spring 36 to the downside clutch component 35 that the top of axis has boosted, pushed to the below of axis by the loading force of compression helical spring 36.Thus, the locking recess 39 of upside clutch component 34 is removed with the fastening state of the locking piece 45 of downside clutch component 35, and the rotary driving force of motor 13 does not transmit from downside clutch component 35 to upside clutch component 34.
In this case, drain valve 9 by the loading force of loaded member from open mode towards closed condition will return action, but the state that the rotation of the housing 48 of planetary gears 29 has been prevented from as described above is maintained, and as shown in Figure 6, the locking piece 75 of cam lever 68 is locking with the locking pawl 37 of upside clutch component 34, being prevented to reciprocal rotation of upside clutch component 34.Its result, being prevented to reciprocal rotation of driven member 49 (with reference to Fig. 5), can remain open mode by drain valve 9.
If make drain valve 9 with becoming open mode through the stipulated time as described above, then motor 13 is by stoppings such as timers.Thus, rotor 19 and motor pinion 22 stop, first middle solid of rotation 81 (with reference to Fig. 7) stops, the input side rotating member 97 (with reference to Fig. 7) of driving mechanism 80 stops, on the other hand, as shown in figure 12, middle rotating member 99 rotates slightly toward other direction E under the effect of the inertial force produced by its deadweight.Now, because the detent force (location torque) of input side rotating member 97 by rotor 19 locks in sense of rotation, so the rotation produced by inertial force of middle rotating member 99 through planetary pinion 100 rotation and revolution transmit to outlet side rotating member 101, outlet side rotating member 101 is followed middle rotating member 99 and is rotated slightly toward other direction E.
Thus, second middle solid of rotation 82 slightly rotates to a direction F, stop, with lever 79, linking with to the subconvolute second middle solid of rotation 82 of a direction F, and swung (arrow with reference to Figure 12) towards stopping removing position D from stop position C by the tensile force of draft helical spring 93.Like this, because except the tensile force of draft helical spring 93, also utilize the rotating force produced by the inertia of middle rotating member 99, make stopping lever 79 remove position D from stop position C to stopping to swing, so the tensile force of draft helical spring 93 can not be made to increase, the first locking pawl 92 just can be made positively to depart from from the second locking pawl 88.Thus, can suppress the maximization of the maximization of draft helical spring 93 and motor type actuator 10.
(5) thus, as shown in Figure 9, first locking pawl 92 departs from from the second locking pawl 88, and the rotation of the rotation of the rotation of stopping solid of rotation 78, speed governing solid of rotation 83 (with reference to Fig. 2) and the housing 48 (with reference to Fig. 2) of planetary gears 29 is allowed.Its result, stop power not roll pulley 12 to steel wire by the locking piece 75 of the cam lever 68 shown in Fig. 6 with the despining of the locking upside clutch component 34 obtained of locking pawl 37 of upside clutch component 34 to transmit, steel wire is rolled pulley 12 and is rotated to transport direction A by the loading force of loaded member, steel wire 15 is rolled pulley 12 from steel wire and is sent, drain valve 9 is closed, and carries out return action to A-stage.
Now, the skate 70 of cam lever 68, from the abutting status releasing of raised 65 (with reference to Fig. 6) rolling pulley 12 to steel wire, as shown in Figure 4, with sliding wall 64 sliding contact.Thus, the side of the opposing party of the circumference in the front end of operating sheet 71 abuts with downside hub portion 43, as shown in Figure 5, downside clutch component 35 boosts to the top of axis with revolting the restoring force of compression helical spring 36, becomes the state that the upside locking recess 39 of clutch component 34 has engaged with the locking piece 45 of downside clutch component 35.Its result, when the return action from open mode to closed condition of drain valve 9, locking recess 39 engages with locking piece 45, and the detent force (location torque) of the rotor 19 produced by the magnetic force of motor 13 is transmitted to upside clutch component 34.Thus, being prevented to reciprocal rotation of upside clutch component 34.
And then, when the return action from open mode to closed condition of above-mentioned drain valve 9, rotate to transport direction A because pulley 12 (with reference to Fig. 3) rolled by steel wire, so the rotation rolling pulley 12 with steel wire links, the driven member 49 (with reference to Fig. 5) of output wheel 32 (with reference to Fig. 5) and planetary gears 29 rotates to the direction of batching phase anti-with steel wire, but because the rotation of housing 48 is allowed, and being prevented to reciprocal rotation of sun gear 38, so link with driven member 49, housing 48 rotates, the rotation of housing 48 (with reference to Fig. 2) is transmitted to speed governing solid of rotation 83 (with reference to Fig. 2), speed governing solid of rotation 83 rotates, and stop rotating with solid of rotation 78 (with reference to Fig. 2).Thus, as shown in Figure 2 and Figure 3, because each slide mass 120 of speed governing solid of rotation 83 is expanded outward by centrifugal force radius vector, with the inner peripheral surface sliding contact of cylindrical part 121, speed governing solid of rotation 83 acts on braking force, the rotational speed of housing 48 is conditioned, so the rotational speed to transport direction A that pulley 12 rolled by steel wire is conditioned, the speed during return action from open mode to closed condition of drain valve 9 is conditioned.
In the above-described embodiment, as shown in Figure 1, be provided with the first middle solid of rotation 81 engaged with the input side rotating member 97 of motor pinion 22 and driving mechanism 80 and the second middle solid of rotation 82 engaged with outlet side rotating member 101 and stopping lever 79, but first and second middle solid of rotation 81,82 also can not be set, motor pinion 22 and input side rotating member 97 directly link link, and outlet side rotating member 101 and stopping lever 79 directly link link.In the case, driving mechanism 80 is arranged on the top of motor 13.In addition, also slide mass 120 (with reference to Fig. 2) can be set on stopping solid of rotation 78 (with reference to Fig. 2), the function of additional speed governing gear, is linked by relaying solid of rotation and links the stopping solid of rotation 78 of this band speed-regulating function and the housing 48 of planetary gears 29.
In the above-described embodiment, the example as object lists the drain valve 9 of washing machine, but is not limited to drain valve 9.
