And it is located on the end position (the second settling position) of heart-shaped guide groove 314 (referring to Fig. 8 B).
Fig. 7 B corresponds to the explosion installation diagram of Fig. 7 A.
Fig. 8 A is shown, when under promotion of the cam 302 in external force (such as user push electrical equipment door) from unlocking condition to
When blocking rotates, sliding pin 316 is in heart-shaped guide groove 314 from initial position A to the moving process of end position C.Such as figure
Shown in 8A, as initial position A of the sliding pin 316 in heart-shaped guide groove 314, electrical equipment door (not shown) is in enabling shape
State, when external force pushes electrical equipment door to progressively close off, the gate stop 107 being mounted on electrical equipment door gradually passes through door lock hole
105, into the opening 308 on the head of cam 302, and cam 302 is pushed to be rotated counterclockwise, is slided so that cam 302 drives
Pin 316 gradually shifts to heart-shaped guiding from the initial position A of heart-shaped guide groove 314 along heart-shaped guide groove (i.e. positioning device) 314
First bottom position B of slot 314, the cell wall 337 that rotation passes through its vertical shape counterclockwise of cam 302 drives torsional spring at the same time
312 the first stress section 323.1Rotary force is applied to torsional spring 312, torsional spring 312 is in and rotatably compresses state, and make torsional spring 312
Accumulate potential energy.When cam 302 reaches blocking from unlocking condition, cam 302 correspondingly drives sliding pin 316 to reach heart and leads
To the first bottom position B of slot 314.When external force disappears, torsional spring 312 is retracted rotate by a certain angle clockwise, thus torsional spring 312
Certain potential energy is discharged, gate stop 107 is retracted a small distance by torsional spring 312.Since the bias force of torsional spring 312 is applied to sliding pin
The angle of first bottom position B of 316 angular compliance heart guide groove 314, so that sliding pin 316 is from the first bottom position B quilt
Keyed end (end position) C of heart-shaped guide groove is shifted onto.Because keyed end C be triangle recess and torsional spring 312 it is inclined
Power collective effect is set, so sliding pin 316 is fixed on keyed end C, torsional spring 312 and cam 302 just cannot continue clockwise at this time
Rotation, and correspondingly rested on locked position of coupler；Meanwhile the cam hook 304 of cam 302 is stretched outside in the door stop hole 109 of gate stop 107
Gate stop 107 (see Fig. 6) has been caught on, thus gate stop 107 has also been kept in locked position of coupler.It should be noted that on torsional spring 312
After releasing certain potential energy, torsional spring 312 is still within compressed state, because sliding pin 316 has been fixed on keyed end C.
When cam 302 and gate stop 107 are maintained at locked position of coupler, as being described in detail below in conjunction with Fig. 9 B, sliding block 902
Can be mobile to the direction of cam 302, and it is inserted into the bottom of cam 302 (see Fig. 9 B).At this point, if user presses electrical equipment
Start key on (such as washing machine), then door lock driving box 212 can stretch out lock tongue (not shown) and block sliding block 902, make sliding block 902
It can not be retracted from the bottom of cam 302, to further locking cam 302 and gate stop 107 in locked position of coupler, and then set electric appliance
Standby door is lockable.
And when cam 302 and gate stop 107 are maintained at locked position of coupler, if user does not press electrical equipment (such as
Washing machine) on start key, door lock driving box 212 just will not stretch out lock tongue and blocks sliding block 902, at this point, as below in conjunction with
Fig. 8 B is described in detail, if pushing the door of electrical equipment with external force, the opening of electrical equipment door can be achieved.
Fig. 8 B is shown, when under promotion of the cam 302 in external force (such as user push electrical equipment door) from blocking to
When unlocking condition rotates, sliding pin 316 is in heart-shaped guide groove 314 from end position C to the moving process of initial position A.Assuming that
Electrical equipment work at this time finishes (the laundry process of such as washing machine terminates), and door lock drives box 212 to retract lock tongue (not shown), releases
It puts by the sliding block 902 that blocks of lock tongue of door lock driving box 212, to discharge electrical equipment door (it may be noted that electrical equipment at this time
Door is still to be maintained at locked position of coupler by cam 302 and gate stop 107, and be not switched on).
At this point, being stuck in the opening 308 on the head of cam 302 if user pushes the door (not shown) of electrical equipment
Gate stop 107 push cam 302 to rotate counterclockwise, so that cam 302 drives sliding pin 316 along heart-shaped guide groove 314 from heart
The keyed end C of guide groove 314 shifts to the second bottom position D of heart-shaped guide groove 314.Since the angle of keyed end C is arranged, so that
Sliding pin 316 shifts to the second bottom position D and irrevocable first bottom position B from keyed end C.
When external force disappears, the potential energy on torsional spring 312 will drive cam 302 to rotate clockwise, and drive sliding pin 316 from heart
Second bottom position D of guide groove 314 is moved to the initial position A of heart-shaped guide groove 314, so that cam 302 returns to out
Lock status；Meanwhile under the driving of torsional spring 312, the cam 302 rotated clockwise will also be inserted into the sliding block 902 of its bottom from
(see Fig. 9 A) is released in its bottom, and gate stop 107 is popped up from door lock hole 105, so that electrical equipment door is opened.
It should be noted that the door of electrical equipment is usually that hinge is relied on to be installed on electrical equipment, generated when rotating
Resistance very little, and as Fig. 9 A, 9B will shown in, 902 tail portion of connection sliding block simultaneously pushes sliding block 902 to go to resist cam
The thrust of 302 sliding block spring 906 also very little, and the turning power for the torsional spring 312 for being used to that cam 302 to be driven to rotate clockwise compared with
It greatly, therefore, is the sliding block 902 from its for being enough to drive cam 302 by 302 bottom of cam is inserted by the turning power of torsional spring 312
(see Fig. 9 A) is released in bottom, and simultaneously pops up gate stop 107 from door lock hole 105, to open electrical equipment door.
