D) fork 27 212 stretches out spring base 213 in its axis of symmetry towards spring base, and spring 211 is a cylindroid helical-coil compression spring, is placed between spring base 212 and the spring base 213, and is in most compressed state when its axis overlaps with the axis of symmetry of fork 27.
The binding post 23 of solenoid 24 is access to the output of the controller of washing machine, under the control of controller:
---when solenoid 24 passes to the DC current of a direction in short-term, attract armature 27a, drive tension force that fork 27 overcomes spring 211 around axle 25 counter-clockwise swings until being stopped by the end face of solenoid 24, draw dead bolt 28 simultaneously along slideway 29 retractions, leave snap close and release.
---when solenoid 24 passes to rightabout DC current in short-term, repulsion armature 27a, driving fork 27 overcomes the tension force of spring 211 to be swung until being stopped by link stopper 22 clockwise around axle 25, promotes dead bolt 28 simultaneously and stretches out along slideway 29, enters snap close and locking.
This embodiment also can revise design as 1 pair of dead bolt of embodiment and spring.
The 3rd embodiment
This embodiment mainly is that rock-steady structure does not adopt the fork spring with respect to the 2nd embodiment.
Fig. 5 and Fig. 6 are respectively that the dead bolt of this embodiment washing machine hood door lock is in released state and blocking structural representation.As scheme to arrange:
A) be fixed in having of lock housing 310:
---solenoid 34, its central axis hole are arranged Permanentmagnet bar armature 37a, constitute the helix tube type DC electromagnet;
---slideway 39 is positioned at the extended line of solenoid 34 axis;
B) end of the dead bolt 38 of direct rod shape is fixed in armature 37a end along axis, and the other end navigates within slideway 39;
C) cylindroid helical-coil compression spring 311 1 end circles are fixed in lock housing 310 and are the spring base 312 of one, other end circle is configured as the depression bar 313 of sphere through a top, press to dead bolt 38 along the direction vertical with slideway 39, the position over against depression bar 313 when dead bolt is configured as the pit 38a that depresses on its sphere top and release over against the position of depression bar 313 when locking is configured as the pit 38b that depress on its sphere top.Dead bolt also is configured as the suitable protuberance 314 of a circle between pit 38a and 38b, depression bar 313 produces bigger compression at this to spring 311, strengthens the antijamming capability of rock-steady structure.
The binding post 33 of solenoid 34 is access to the output of the controller of washing machine, under the control of controller:
---when solenoid 34 passes to the DC current of a direction in short-term, attract armature 37a, traction dead bolt 38 along slideway 39 retractions, leaves snap close and release; Therebetween, promote deformation force that depression bar 313 overcomes spring 311 original settling position---the pit 38a that jumps out, and then cross protuberance 314, arrive new settling position---pit 38b;
---when solenoid 24 passed to rightabout DC current in short-term, repulsion armature 37a promoted dead bolt 38 and stretches out along slideway 39, enters snap close and locking; Therebetween, promote deformation force that depression bar 313 overcomes spring 311 original settling position---the pit 38b that jumps out, and then cross protuberance 314, arrive new settling position---pit 38a.
The rock-steady structure of this embodiment also can be revised design:
Depression bar is changed into one be fixed in lock housing and be the permanent magnet of the N utmost point towards the working end of dead bolt, dead bolt changes straight rod that a nonmagnetic substance makes into and each fixes the permanent magnet that a working end is the S utmost point in described two groove position (protuberance 314 cancellations).Like this, dead bolt is when locking and release, and the permanent magnet that this two permanent magnet is fixed respectively attracts, and the motion of dead bolt overcomes this magnetic force with need, plays the position stability effect that external force resistance is disturbed.Permanent magnet fixing on the dead bolt also can change common ferrous materials into, and at this moment, polarity can not be considered in the installation of being fixed in the permanent magnet of lock housing.
