(lock out action of lid lock device 100)

Fig. 8 be applied from the side L1 of Y-direction lid lock device 100 of the invention linear actuators 1 it is vertical Body figure, Fig. 8 (a) are the situations for showing the linear actuators 1 when the lid 230 from the other side L2 of Y-direction is located at open position Perspective view, Fig. 8 (b) are standing for the situation of the linear actuators 1 when lid 230 is located at closed position from the other side L2 of Y-direction Body figure.

In the lid lock device 100 of present embodiment, if lid 230 is in open state as shown in Fig. 1 (a), (b) When, the extension 91 of lid detection part 9 be along the posture of the base plate 111 of first shell 11, then as shown in Fig. 7 (a), The protrusion 95 of lid detection part 9 via the base plate 111 for being formed in first shell 11 opening portion 111c, from opening for retainer 60 Oral area 64c is prominent to the other side Y2 of Y-direction.In this state, the inclined-plane 951 of protrusion 95 is connected to the opening portion of retainer 60 The edge of 64c, therefore retainer 60 is mobile to the side L1 in the direction axis L.As a result, due to driving gear 30 to the axis side L To side L1 it is mobile, therefore as shown in Fig. 8 (a), gear 30 is driven to engage with the second driven gear 42, but with first from The engagement of moving gear 41 is released from.In this state, even if motor 20 rotates, the first driven gear 41 and the second driven gear 42 also not relative rotation but rotate together, therefore the second driven gear 42 and locking member 8 (output block 80) not by The side L1 in the direction axis L drives.In this way, which lid detection part 9 is configured to as clutch part 7, clutch part 7 is to horse Structural connection up to 20 and locking member 8 (output block 80) is attached and disconnects.

In this regard, as shown in Fig. 1 (c), if lid 230 is closed state, the extension 91 of lid detection part 9 is to the one of Y-direction Side Y1 is mobile, as a result, since protrusion 95 is de- from the opening portion 64c of retainer 60 and the opening portion 111c of first shell 11 From therefore as shown in Fig. 7 (b) and Fig. 8 (b), retainer 60 is by the active force of helical spring 69 to the another of the direction axis L Side L1 is mobile.As a result, since driving gear 30 is mobile to the other side L1 in the direction axis L, driving gear 30 with First driven gear 41 and this two side of the second driven gear 42 engagement.Therefore, if closing after lid 230, user is in equipment master 210 side of body carries out switch operation to start washing, drying, then motor 20 is rotated to a direction, due to the first driven gear 41 With 42 relative rotation of the second driven gear, therefore the second driven gear 42 by the side L1 in the direction axis L drive.Therefore, by It is driven in locking member 8 (output block 80) to the side L1 in the direction axis L, therefore the lock shaft 85 of locking member 8 is chimeric And be sticked in engaged part 236, to lock lid 230.Next, the axis side L of the second guide portion 82 in locking member 8 To side L1 end 820 and the position that limiting unit 127 abuts shown in Fig. 2 (b), keep locking member 8 and second driven Gear 42 stops.

Also, if locking member 8 (output block 80) is driven to the side L1 in the direction axis L, movable member 28 Rotation is allowed.Therefore, because the input unit 270 of 286 push switch 27 of the first protruding portion, therefore locking member 8 is to the axis side L To this mobile signal of latched position of side L1 exported by connector 26 to control unit.As a result, control unit make to The power supply of motor 20 stops, and the state for maintaining lid 230 locked by locking member 8.

Next, if motor 20 is rotated to other direction, thus the second driven gear 42 if washing, drying terminate It is driven to the other side L2 in the direction axis L.Therefore, because locking member 8 (output block 80) is by the another of the direction axis L Side L2 driving, therefore the lock state of lid 230 is released from.Therefore, lid 230 can be opened.

(structure of operating member 65)

As shown in Figure 7 and Figure 8, the side X1 operating member 65 outstanding for constituting oriented X-direction in retainer 60, operation Component 65 is in the state that the side X1 from shell 10 to X-direction is prominent and exposes.In the present embodiment, operating member 65 Play the role of as clutch part 7 below: making to drive gear 30 (the first driving gear 31 and the second driving gear 32) Moved along the direction axis L, thus release the first driving gear 31 and the first driven gear 41 engage and second drives gear 32 at least one party in the engaging of the second driven gear 42.In the present embodiment, operating member 65 makes to drive gear 30 (the One driving gear 31 and the second driving gear 32) it is mobile to the side L1 in the direction axis L, thus making the second driving gear 32 In the state of engaging with the second driven gear 42, the first driving gear 31 of releasing is engaged with the first driven gear 41.

More specifically, as shown in Fig. 7 (b) and Fig. 8 (b), in the state that lid 230 is locked by locking member 8, Retainer 60 also is located at the other side L2 in the direction axis L.Therefore, operating member 65 also is located at the other side L2 in the direction axis L.? Under the state, the first driving gear 31 is engaged with the first driven gear 41, and the second driving gear 32 is nibbled with the second driven gear 42 It closes.Therefore, if, since motor 20 does not rotate, lid 230 can not be opened if having a power failure in this state.

In this case, if by making operating member 65 to the side L1 in the direction axis L movement, retainer manually 60 and driving gear 30 it is mobile to the side L1 in the direction axis L, so as to make the second driving gear 32 and second driven In the state that gear 42 engages, the first driving gear 31 of releasing is engaged with the first driven gear 41.Here, the second driven gear 42 are exerted a force by force application part 51 to the other side L21 in the direction axis L.If also, the first driven gear 41 and first drives gear If 31 engagement is released from, then the first driven gear 41 and the second driven gear 42 can rotate independently.Also, Between one driven gear 41 and the second driven gear 42, inclining for the inclined cam surface 414 of rotation direct action converting mechanism 50 is constituted Oblique angle is bigger than inclined cam surface 414 and the angle of friction of sliding part 424.Therefore, the second driven gear 42 by force application part 51 to The other side L21 in the direction axis L exerts a force, as a result, sliding part 424 presses inclined cam surface 414, thus the first driven tooth Wheel 41 or the second driven gear 42 rotate on one side, and sliding part 424 moves on one side in inclined cam surface 414.Therefore, because Locking member 8 (output block 80) is driven to the other side L2 in the direction axis L, therefore the lock state of lid 230 is released from.Cause This, lid 230 can be by opening manually.

(main effect of present embodiment)

As described above, in the lid lock device of present embodiment 100, if motor 20 (driving source) driving the One driving gear 31 and the second driving gear 32, then the first driven gear 41, the Yi Jiyu engaged with the first driving gear 31 The second driven gear 42 rotation that second driving gear 32 engages.At this moment, due to the first driving gear 31 and the first driven gear 41 gear ratio and the second driving gear 32 are different from the gear ratio of the second driven gear 42, therefore the first driven gear 41 and the Two driven gears, 42 relative rotation (differential).Therefore, if by rotation direct action converting mechanism 50, by the phase of the second driven gear 42 The movement that second driven gear 42 is moved along the direction axis L is transformed to for the relative rotation of the first driven gear 41, then can It is interlocked with the second driven gear 42 and output block 80 (locking member 8) is made to move linearly.

Also, the first driving gear 31 and in the present embodiment, are made by lid detection part 9 (clutch part 7) At least one party in two driving gears 32 moves along the direction axis L, to release the first driving gear 31 and the first driven gear 41 Engagement and the engaging of the second driving gear 32 and the second driven gear 42 at least one party.Therefore, even if passing through horse In the state of driving the first driving gear 31 and the second driving gear 32 up to 20, it can also stop the second driven gear 42 Linear drives.Therefore, even if utilizing the differential come straight of two gears (the first driven gear 41 and the second driven gear 42) In the case that line drives output block 80, at least one in the first driving gear 31 and the second driving gear 32 is made by setting Clutch part 7 (lid detection part 9) this simple structure that side is moved along the direction axis L, also can be to (the driving of motor 20 Source) the structural connection with output block 80 is attached and disconnects.

Also, since the first driving gear 31 and the second driving gear 32 are constituted as integrated driving gear 30, because This, which can be realized, makes gear mechanism the structure can be simplified.Also, driving gear 30 in, first driving gear 31 tooth and The tooth of second driving gear 32 is continuously formed in the direction of the axisl.Therefore, because the number of teeth and second of the first driving gear 31 It drives the number of teeth of gear 32 equal, therefore keeps the first driven gear 41 different from the number of teeth of the second driven gear 42.According to the knot Structure, in gear mechanism, can be realized makes the first driving gear 31 and the second driving gear 32 the structure can be simplified.And And since in driving gear 30, the tooth of the first driving gear 31 and the tooth of the second driving gear 32 are continuous in the direction of the axisl Ground is formed, therefore it is driven to be easy first driving gear 31 and first of the releasing when making that gear 30 is driven to move along the direction axis L The engagement of gear 41 and the first driving gear 31 and the first driven gear 41 engage.

Also, clutch part 7 makes to drive gear 30 mobile to the side L1 in the direction axis L, to release the first sliding tooth Wheel 31 is engaged with the first driven gear 41.As long as therefore, because releasing the first fixed in the direction of the axisl driven gear 41 It is engaged with driving gear 30, therefore drives the moving distance to the direction axis L of gear 30 is shorter can be solved.

Also, it rotates direct action converting mechanism 50 and includes the second driven gear of direction being formed in the first driven gear 41 The inclined cam surface 414 on 42 surface；The sliding part 424 abutted with inclined cam surface 414 in second driven gear 42； And the force application part 51 to exert a force to 41 side of the first driven gear to the second driven gear 42.Therefore, can be realized makes to rotate The structure can be simplified for direct action converting mechanism 50, and force application part 51 is by output block 80 to 41 side of the first driven gear to the Two driven gears 42 force.Therefore, output block 80 can be made to move to the other side L2 in the direction axis L by force application part 51 It is dynamic.

Also, in the present embodiment, motor 20 (driving source) is can to enable that gear 30 is driven to revolve to both direction The stepper motor for turning driving constitutes restricted portion 127 in shell 10, the second driven gear 42 of limitation towards the direction axis L The movable range of side L1.Therefore, the second driven gear 42 and output block 80 can stop in place.Though that is, When being so the motor only rotated to a direction, since the structure stopped can not being used using limiting unit, and need to pass through Timer etc. controls rotational time, but if it is can to bidirectional rotation motor if, limiting unit 127 can be passed through Second driven gear 42 and output block 80 are stopped in place.

Also, the linear actuators 1 of present embodiment is installed in lid lock device 100, and lid detection part 9 as from It closes component 7 and constitutes.Therefore, when lid 230 is in open position, the driving of locking member 8 (output block 80) can be stopped.

Also, after the second driven gear 42 is mobile to the side L2 in the direction axis L, the quilt of locking member 8 and lid 230 Holding section 236 engages, therefore the force application part 51 for rotating direct action converting mechanism 50 applies locking member 8 to the direction to unlock Power.Therefore, when by making locking member 8 mobile to the releasing direction of lock state manually, required power can be smaller.

Also, in the present embodiment, by the operating member of peripheral operation 65 as release driving gear 30 and first from The clutch part 7 of the engagement of moving gear 41 and constitute.Therefore, even if being had a power failure in the state that lid 230 is locked, due to As long as operation operating member 65, can release engaging for driving gear 30 and the first driven gear 41, therefore can also open lid 230。

Also, due to a part of operating member 65 from accommodate driving gear 30, motor 20, rotation direct action converting mechanism 50 equal shells 10 expose, therefore can easily operate operating member 65.
