In addition, in the present embodiment, locking component 8 is formed with two disturbed 85,86, and the advance and retreat direction along locking component 8 between locking component 8 and spacing member 7 is provided with a plurality of interference position (interference portion 75 and disturbed the 85 first interference position and the interference portion 75 and disturbed the 86 second interference position that takes place to disturb that interference takes place).In the present embodiment, interference portion 75 is to make locking component 8 stop at the interference position that the position of interference does not take place with lid 230 when open mode moves to closed condition at lid 230 with disturbed the 85 first interference position that interference takes place.In addition, though interference portion 75 with disturbed 86 take place to disturb second disturb the position be locking component 8 advance to can be stuck position that portion 236 engage and also do not produce to lock and finish the interference position that under the state of signal locking component 8 is stopped.In addition, second disturb the position also can be arranged on locking component 8 do not advance to can with the position that is stuck the position that portion 236 engage, promptly locking component 8 stops at the position between stop position that locking component 8 under the operation at the above-mentioned first interference position stops and sense switch 60 moved, become on-state because of slide block 53 position.
(action usually)
In the lid lock device 100 of present embodiment, the control device (not shown) of equipment body 210 sides is by coming motor part 30 power supplies because of the detection of the firing switch (not shown) of equipment body 210 sides or the controls such as beginning washing, dehydration of turning round automatically.Consequently, locking component 8 advances towards+Z direction.
At this moment, from the state shown in Fig. 1 (a) to the state shown in Fig. 1 (b), be in closed condition in case cover 230, shown in Fig. 7 (c) and Fig. 8 (c), the leading section and slide 2 butts of lid 230 protuberance 235, make slide 2 overcome helical spring 98,99 active force and from peristome 13 towards lateral displacement.Consequently, the butt board 23 of slide 2 is backed out from the front side of the direction of advance (+Z direction) of locking component 8.Yet, when the lid 230 shown in Fig. 7 (b) and Fig. 8 (b) is incomplete closing state, slide 2 is made a concession spacing member 7, and spacing member 7 is in disturbed 85,86 position of advancing that be positioned at the front side of the direction of advance that stop locking component 8 of interference portion 75 with respect to locking component 8.Therefore, even to motor part 30 power supplies, locking component 8 also is in the state that advances and be prevented from.
230 become complete closing state at lid, be formed at the portion that is stuck 236 of cover on 230 the protuberance 235 when arriving the position that can engage with the leading section of locking component 8, the leading section that covers 230 protuberance 235 is further pushed slide 2.Consequently, shown in Fig. 7 (c) and Fig. 8 (c), slide 2 and spacing member 7+end 72 butts of Z direction, spacing member 7 is displaced to towards advancing of tilting of the direction away from locking component 8 and allows the position.Consequently, the interference portion 75 of spacing member 7 backs out from disturbed 85 of locking component 8,86 front side.Therefore, locking component 8 allows to advance, the leading section of locking component 8 by crank-pin 511 with crank pit 530 and be formed at the portion that is stuck 236 embedding mutually of covering on 230 the protuberance 235.
In addition, in case slide block 53 court+Z directions advance to the abutting part 53a push projection 63a of portion of the slide block 53 that describes with reference to Fig. 5, operation strip 63 is contacted with stator 64.Therefore,, confirm that the terminal 65,66 of sense switch 60 is in short circuit (contact) state, thereby it can be identified as the 230 blocked states that cover, produce locking and finish signal in equipment body 210 sides.In addition, confirming that locking begins the rotation of cylinder etc. after finishing the generation of signal.Therefore, owing to, be safe therefore in rotations such as lid 230 locked fully cylinders afterwards.
At this, when lid 230 was in open mode or incomplete closed condition, spacing member 7 was in disturbed 85,86 position of advancing that be positioned at the direction of advance front side that stop locking component 8 of interference portion 75 with respect to locking component 8.Therefore, even to motor part 30 power supplies, advancing of locking component 8 also can be prevented from, thereby operation strip 63 can not contact with stator 64.Therefore, in equipment body 210 sides, even to the motor part 30 power supply stipulated times, the terminal 65,66 of sense switch 60 can not become on-state, if confirm as open mode, then can identify and cover 230 and be not in complete closing state.
(opening action of lid 230)
In addition, in case the rotation of cylinder finishes, drive division 3 is driven, in case drive division 3 is driven, owing to make locking component 8 by crank-pin 511 and crank pit 530 and court-Z direction retreats, so can opens and covers 230.Consequently, turn back to the state shown in Fig. 7 (a) and Fig. 8 (a).
(action when under lock-out state, having a power failure)
When having a power failure under lid 230 blocked states, lid 230 keeps blocked state.In this state, the bar portion 87 that is located at locking component 8 is depressed.Consequently, locking component 8 retreats, and covers 230 locking thereby removed.At this moment, therefore different by spring energized structure because the power of pushing crank-pin 511 with crank pit 530 that only moves forward and backward of locking component 8 carries out as reference Fig. 5 is illustrated with slide block, can manually make locking component 8 mobile easily.In addition, under the state of lid 230 locked members 8 lockings, the part at locking component 8 crank-pin 511 places when being stuck portion 236 and engaging becomes the rake 533 with respect to the advance and retreat direction inclination of slide block 53 shown in Fig. 5 (b).Therefore, if utilize bar portion 87 manual moving locking members 8, then since crank-pin 511 by the rake 533 of crank pit 530 with respect to the direction of retreat of locking component 8 towards laterally pushing, therefore, can move glibly, just can manual moving locking member 8 with very little power.
(action when under the state that disturbs takes place, having a power failure)
When the interference portion 75 of spacing member 7 more had a power failure under the state by-Z direction than disturbed 85,86 of locking component 8, lid 230 also kept blocked state.In this state, the bar portion 87 that is located at locking component 8 is depressed.Consequently, locking component 8 retreats, and covers 230 locking thereby removed.At this moment, as reference Fig. 7 (a) and Fig. 8 (a) are illustrated, in the interference portion 75 of spacing member 7, the face 752 that is positioned at the direction of advance (+Z direction) side of locking component 8 is conical surfaces, in disturbed 85,86 of locking component 8, be positioned at the face the 852, the 862nd of direction of retreat (Z direction) side of locking component 8, the conical surface.Therefore, if the direction (Z direction) that manually locking component 8 moved backward is depressed, then interference portion 75 strides across first disturbed 85 and second disturbed 86 easily.Therefore, just can manual moving locking member 8 with less power.
(the main effect of present embodiment)
As discussed above, in the lid lock device 100 of present embodiment, drive division 3 advances locking component 8 so that it engages with lid portion that is stuck 236 of 230 and will cover 230 and be locked into closed condition, thereby and locking component 8 is retreated can cover 230 opening action.In addition,, then finish signal owing to produced locking if locking component 8 finishes to the engaging that is stuck portion 236, therefore can detect cover 230 locked.And, lid 230 be in open mode during because spacing member 7 stops advancing of locking components 8, therefore can not produce locking by mistake and finish signal.
At this, at lid 230 when open mode moves to closed condition, be stuck portion 236 arrive can with position that locking component 8 engages before, spacing member 7 is in interference portion 75 and is positioned at and stops disturbed 85, the position of advancing of 86 direction of advance front side, arrive can be with position that locking component 8 engage the time being stuck portion 236, spacing member 7 is pushed by slide 2 tegmentums 230 and is displaced to interference portion 75 from the permission position of advancing that disturbed 85,86 direction of advance side back out.Therefore, being in semi-closure state etc. at lid 230 is stuck portion 236 and not have arrival can be with position that locking component 8 engages the time, owing to stoped advancing of locking component 8, therefore can not occur locking component 8 not be stuck the situation that portion 236 engages under such situation of advancing.
In addition, between spacing member 7 and locking component 8, be provided with a plurality of disturbed 85,86 and the interference portion 75 interference position that takes place to disturb along the advance and retreat direction of locking component 8.Therefore, even it is unusual to disturb the position to occur at one, also can disturb interference on the position to stop the unusual forward motion of locking component 8 by other.And interference portion 75 is to make locking component 8 stop at the interference position that the position of interference does not take place with lid 230 when open mode moves to closed condition at lid 230 with disturbed the 85 first interference position that interference takes place.Therefore, can avoid covering 230 the such situation of locked member 8 obstruction of closing motion reliably.In addition, though interference portion 75 with disturbed 86 take place to disturb second disturb the position be locking component 8 advance to can be stuck position that portion 236 engage and also do not produce to lock and finish the interference position that under the state of signal locking component 8 is stopped.In addition, interference portion 75 and disturbed 86 take place to disturb second to disturb the position be locking component 8 to be stopped at first disturb the interference position between locking component 8 stop position that stops and the position that sense switch 60 is moved under the effect at position.Therefore, can avoid reliably producing locking when opening such action and finishing the such situation of signal when carrying out to cover 230 midway in lock out action.
In addition, when spacing member 7 tegmentums 230 are pushed, can be around towards the axis rotation of extending with the crossing Y direction of the advance and retreat direction (Z direction) of locking component 8.Therefore, when locking component 8 will advance, the interference portion 75 that can prevent spacing member 7 and locking component 8 disturbed 85,86 interference removed.
And, in the present embodiment, comprise slide 2 as transmission member, this slide 2 be set at cover 230 and spacing member 7 between, when moving to closed condition, open mode will be delivered to spacing member 7 at lid 230 by pushing of applying of lid 230, above-mentioned slide 2 is the same with spacing member 7, also by towards with locking component 8 the position application of force disturbed taking place.Therefore, utilize slide 2 (transmission member) also can stop locking component 8 to advance accidentally.
In addition, in the slider crank mechanism 50 that is adopted in the lid lock device 100 of present embodiment, advancing of locking component 8 need not be undertaken by the active force of spring, and the power of only pushing crank-pin 511 with crank pit 530 is carried out.Therefore, different with slide block 53 by spring energized structure, locking component 8 is easily moved.Therefore, when lid has a power failure under the 230 blocked states, can cover 230 so simple operations lid 230 is opened by when locking component 8 is retreated, opening.In addition, owing to do not come the slide block 53 or locking component 8 application of forces by spring, therefore, even will cover 230 suddenly under 230 the state of covering and open having closed, locking component 8 can not take place yet give prominence to such situation suddenly.
In addition, to be configured to the butt position of above-mentioned crank-pin on top dead-centre and bottom dead centre be that the center is symmetric shape to crank pit 530.Therefore, crank-pin 511 moves towards any one direction can both make slide block 53 rectilinear motions, therefore to the direction of rotation of drive source without limits.Therefore, adopt under the situation of AC motor, also there is no need to be provided with the anti-locking mechanism of reversing in motor part 30.
In addition, crank pit 530 comprises the arc sections 531 of extending along the motion track of crank-pin 511.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 on the Position Control of crank-pin 511, deviation occurs, also can prevent advance the accidentally generation of such abnormal operation of locking component 8.
