In the limit component 7 formed as mentioned above and locking component 8, limit component 7 is in interference portion 75 is positioned at the advance on front side of the direction of advance stoping locking component 8 position relative to the disturbed portion 85,86 of locking component 8.Therefore, during the interference portion 75 of limit component 7 is positioned at the front side of direction of advance (+Z-direction) of locking component 8 relative to the disturbed portion 85,86 of locking component 8, even if power to motor part 30, locking component 8 is also in the state of advancing and being prevented from.At this, as described later, when lid 230 becomes closed condition and the engaged part 236 being formed at the protuberance 235 of lid 230 arrives the position that can engage with the leading section of locking component 8, limit component 7 is pressed by slide 2, thus is displaced to the advance allowing locking component 8 to advance and allows position.Therefore, slide 2 plays the effect pressing undertaken by lid 230 being delivered to the transmission member of limit component 7.
In addition, in the present embodiment, locking component 8 is formed with two disturbed portions 85,86, be provided with along the advance and retreat direction of locking component 8 between locking component 8 and limit component 7 multiple interference position (interference portion 75 and disturbed portion 85 occurs to disturb first disturb position and interference portion 75 and disturbed portion 86 to occur to disturb second disturb position).In the present embodiment, what interference portion 75 and disturbed portion 85 occurred to disturb first disturbs position to be make locking component 8 stop at lid 230, the interference position of the position of disturbing not to occur when lid 230 moves to closed condition from open mode.In addition, though interference portion 75 and disturbed portion 86 occur to disturb second disturb position to be advance at locking component 8 the interference position under the position that can engage with engaged part 236 does not produce the state locking settling signal yet, locking component 8 being stopped.In addition, second interference position also can be arranged on the position that locking component 8 does not advance to the position that can engage with engaged part 236, namely locking component 8 stop at the stop position of locking component 8 stopping under the operation at above-mentioned first interference position and sense switch 60 action because of slide block 53, become on-state position between position.
(usual action)
In the lid lock device 100 of present embodiment, the control device (not shown) of equipment body 210 side is by because of the detection of the firing switch (not shown) of equipment body 210 side or running and start the controls such as washing, dehydration and power to motor part 30 automatically.Consequently, locking component 8 advances towards+Z-direction.
Now, state shown in from the state shown in Fig. 1 (a) to Fig. 1 (b), once lid 230 is in closed condition, as shown in Fig. 7 (c) He Fig. 8 (c), the leading section of protuberance 235 of lid 230 abuts with slide 2, make slide 2 overcome helical spring 98,99 active force and from opening portion 13 towards lateral displacement.Consequently, the abutting plate portion 23 of slide 2 backs out from the front side of the direction of advance (+Z-direction) of locking component 8.But, when the lid 230 such as shown in Fig. 7 (b) He Fig. 8 (b) is the state of not exclusively closing, slide 2 does not make limit component 7 make a concession, and limit component 7 is in interference portion 75 is positioned at the advance of the front side of the direction of advance stoping locking component 8 position relative to the disturbed portion 85,86 of locking component 8.Therefore, even if power to motor part 30, locking component 8 is also in the state of advancing and being prevented from.
When the engaged part 236 that lid 230 becomes on the state of closing completely, the protuberance 235 being formed at lid 230 arrives the position that can engage with the leading section of locking component 8, the leading section of the protuberance 235 of lid 230 presses slide 2 further.Consequently, as shown in Fig. 7 (c) He Fig. 8 (c), slide 2 and limit component 7+end 72 of Z-direction abuts, and limit component 7 is displaced to the advance permission position tilted towards the direction away from locking component 8.Consequently, the interference portion 75 of limit component 7 backs out from the front side in the disturbed portion 85,86 of locking component 8.Therefore, locking component 8 allows to advance, and the leading section of locking component 8 is mutually embedding with the engaged part 236 be formed on the protuberance 235 of lid 230 by crank-pin 511 and crank pit 530.
In addition, once slide block 53 advances to the abutting part 53a push projection portion 63a of the slide block 53 be described with reference to Fig. 5 towards+Z-direction, movable plate 63 will be made to contact with stator 64.Therefore, in equipment body 210 side, confirm that the terminal 65,66 of sense switch 60 is in short circuit (contact) state, thus the locked state of lid 230 can be identified as, produce locking settling signal.In addition, after the generation confirming locking settling signal, start the rotation of cylinder etc.Therefore, due in rotations such as the completely locked back rolls of lid 230, be therefore safe.
At this, when lid 230 is in open mode or incomplete closed condition, limit component 7 is in interference portion 75 is positioned at the advance on front side of the direction of advance stoping locking component 8 position relative to the disturbed portion 85,86 of locking component 8.Therefore, even if power to motor part 30, the advance of locking component 8 also can be prevented from, and thus movable plate 63 can not contact with stator 64.Therefore, in equipment body 210 side, even if power the stipulated time to motor part 30, the terminal 65,66 of sense switch 60 can not become on-state, if the open mode of confirming as, then can identify lid 230 and not be in the state of closing completely.
(opening action of lid 230)
In addition, once the rotation of cylinder terminates, drive division 3 is driven, once drive division 3 is driven, owing to making locking component 8, by crank-pin 511 and crank pit 530, court-Z-direction retreats, and therefore can open lid 230.Consequently, the state shown in Fig. 7 (a) He Fig. 8 (a) is turned back to.
(action when having a power failure in the locked state)
When having a power failure under the state that lid 230 is locked, lid 230 keeps locked state.In this state, the bar portion 87 being located at locking component 8 is depressed.Consequently, locking component 8 retreats, thus relieves the locking of lid 230.Now, as with reference to illustrated by Fig. 5, because moving forward and backward of locking component 8 is only undertaken by the power that crank pit 530 presses crank-pin 511, therefore, different from the structure that slide block is exerted a force by spring, manually can make locking component 8 easily movement.In addition, under the state that lid 230 is locked component 8 locking, when locking component 8 engages with engaged part 236, the part at crank-pin 511 place becomes the rake 533 tilted relative to the advance and retreat direction of slide block 53 as shown in Fig. 5 (b).Therefore, if utilize the manual moving locking member 8 in bar portion 87, then due to crank-pin 511 by the rake 533 of crank pit 530 relative to the direction of retreat of locking component 8 towards horizontal pressing, therefore, can move glibly, just can manual moving locking member 8 by very little power.
(action when having a power failure under the state that interference occurs)
The interference portion 75 of limit component 7 than the disturbed portion 85,86 of locking component 8 more by the state of-Z-direction under have a power failure time, lid 230 also keeps locked state.In this state, the bar portion 87 being located at locking component 8 is depressed.Consequently, locking component 8 retreats, thus relieves the locking of lid 230.Now, illustrated by with reference to Fig. 7 (a) and Fig. 8 (a), in the interference portion 75 of limit component 7, the face 752 being positioned at the direction of advance (+Z-direction) side of locking component 8 is conical surfaces, in the disturbed portion 85,86 of locking component 8, the face 852,862 being positioned at the direction of retreat (-Z-direction) side of locking component 8 is conical surfaces.Therefore, if manually locking component 8 to be moved backward direction (-Z-direction) pressure, then interference portion 75 easily strides across the first disturbed portion 85 and the second disturbed portion 86.Therefore, just can manual moving locking member 8 by less power.
(main efficacy results of present embodiment)
As discussed above, in the lid lock device 100 of present embodiment, drive division 3 makes locking component 8 advance to make it to engage with the engaged part 236 of lid 230 and lid 230 is locked into closed condition, and locking component 8 is retreated thus can carry out the opening action of lid 230.In addition, if locking component 8 completes to the engaging of engaged part 236, then owing to creating locking settling signal, therefore can detect that lid 230 is locked.And, during lid 230 is in open mode, because limit component 7 stops the advance of locking component 8, therefore can not produce locking settling signal by mistake.
At this, when lid 230 moves to closed condition from open mode, before arriving the position that can engage with locking component 8 in engaged part 236, limit component 7 is in the position that interference portion 75 is positioned at the advance on front side of the direction of advance stoping disturbed portion 85,86, when arriving the position that can engage with locking component 8 in engaged part 236, limit component 7 is pressed by slide 2 tegmentum 230 and is displaced to the advance permission position backed out from the direction of advance side in disturbed portion 85,86 in interference portion 75.Therefore, be at lid 230 engaged parts 236 such as semi-closure state do not have arrive can engage with locking component 8 position time, owing to preventing the advance of locking component 8, locking component 8 is therefore there will not be to advance when not engaging with engaged part 236 such situation.
In addition, between limit component 7 and locking component 8, the interference position that multiple disturbed portion 85,86 and interference portion 75 occur to disturb is provided with along the advance and retreat direction of locking component 8.Therefore, even if occur abnormal at an interference position, the forward motion of the exception of locking component 8 is also stoped by the interference on other interference position.And what interference portion 75 and disturbed portion 85 occurred to disturb first disturbs position to be make locking component 8 stop at lid 230, the interference position of the position of disturbing not to occur when lid 230 moves to closed condition from open mode.Therefore, the closing motion of lid 230 reliably can be avoided to be locked component 8 and hinder such situation.In addition, though interference portion 75 and disturbed portion 86 occur to disturb second disturb position to be advance at locking component 8 the interference position under the position that can engage with engaged part 236 does not produce the state locking settling signal yet, locking component 8 being stopped.In addition, what interference portion 75 and disturbed portion 86 occurred to disturb second disturbs position to be locking component 8 is stopped at disturb first the interference position between stop position and the position making sense switch 60 action because of slide block 53 that under the effect at position, locking component 8 stops.Therefore, can reliably avoid when carrying out producing locking settling signal such situation when lid 230 being opened in lock out action midway such action.
In addition, when limit component 7 tegmentum 230 presses, can rotate around the axis extended towards the Y-direction crossing with the advance and retreat direction (Z-direction) of locking component 8.Therefore, when locking component 8 will advance, can prevent the interference portion 75 of limit component 7 from removing with the interference in the disturbed portion 85,86 of locking component 8.
And, in the present embodiment, comprise the slide 2 as transmission member, this slide 2 is arranged between lid 230 and limit component 7, when lid 230 moves to closed condition from open mode, the pressing applied by lid 230 is delivered to limit component 7, above-mentioned slide 2 is the same with limit component 7, is also exerted a force by towards the position occurring to disturb with locking component 8.Therefore, utilize slide 2 (transmission member) that locking component 8 also can be stoped accidentally to advance.
In addition, in the slider crank mechanism 50 adopted in the lid lock device 100 of present embodiment, the advance of locking component 8 need not be undertaken by the active force of spring, and is only undertaken by the power that crank pit 530 presses crank-pin 511.Therefore, different from the structure that slide block 53 is exerted a force by spring, can manually make locking component 8 easily move.Therefore, when having a power failure under the state that lid 230 is locked, by opening the so simple operation of lid 230 while making locking component 8 retreat, lid 230 is opened.In addition, owing to not exerted a force to slide block 53 or locking component 8 by spring, therefore, even if suddenly opened by lid 230 under the state closing lid 230, locking component 8 outstanding such situation suddenly can not also be there is.
In addition, crank pit 530 to be configured to centered by the abutting portion of above-mentioned crank-pin on top dead-centre and bottom dead centre symmetrically shape.Therefore, crank-pin 511 moves towards any one direction can make slide block 53 rectilinear motion, does not therefore limit the direction of rotation of drive source.Therefore, when motor part 30 adopts AC motor, also there is no need to arrange the anti-locking mechanism of reversing.
In addition, crank pit 530 comprises the arc sections 531 that the motion track along crank-pin 511 extends.Therefore, as long as in the arc sections 531 of crank pit 530, no matter which position crank-pin 511 is positioned at, and the position of locking component 8 is all identical.Therefore, even if there is deviation in the position control of crank-pin 511, the generation of the careless such abnormal operation that advances of locking component 8 also can be prevented.
