Pull door-plate, as shown in Figure 14, Figure 15, the movement relation of rotating member 1 and the first locked component are as follows: when on door-plate Door, which hooks, pulls rotating member 1 to overturn, and the first lock face 4 promotion closing piece 17 on rotating member 1 overcomes the biasing force of closing piece return unit 27 Mobile or rotation, when the first lock face 4 on rotating member 1 and the disengaging of the closing piece lock face 19 on closing piece 17, door hooks completely de- From door lock, door-plate is opened.Closing piece 17 comes back to 17 initial position of closing piece under the biasing force of closing piece return unit 27 at this time, can Carry out the movement of locking next time.The movement relation of rotating member 1 and the second locked component are as follows: the door on door-plate, which hooks, pulls rotating member 1 Overturning, the rotating member 1 push locking level 29 to overcome the second return unit 32 mobile, until door hook completely disengages door lock, door-plate is beaten It opens.

Start locking function, as shown in Figure 16, Figure 18, rotating member 1 is located at 1 latched position of rotating member, 6 work of electrical box at this time Make, peach heart sliding block 35 is mobile to drive limited block 33 to protrude electrical box 6, and locating part is extend into the limited block through-hole 31 of locking level 29 The locking level 29 is locked, locking level 29 locks rotating member 1 at this time, and rotating member 1 can not be overturn, and door of washing machine is locked at this time, It can not open.

After electric appliance completes work, as shown in Figure 16-Figure 19, the coil in electrical box 6, which is powered, drives peach core sliding block toward line It is mobile to enclose direction, peach heart sliding block 35 drives limited block 33 to be detached from locating part through-hole, releases the locking to rotating member 1.Peach core sliding block Drive solution lock slide 24 and solving locking key 25 mobile toward coil direction simultaneously, solving locking key 25 drives the first sliding block 20 and closing piece 17 toward line It is mobile to enclose direction.The first lock face 4 on closing piece lock face 19 and rotating member 1 on closing piece 17 is separated, rotating member 1 by turn The biasing force of moving part return unit 5, rotating member 1 push locking level 29 mobile.Rotating member 1 is turned to 1 initial position of rotating member at this time, Door, which hooks, completely disengages door lock, realizes door lock automatic unlocking function.When peach core sliding block drives solving locking key 25 to encounter the guiding on pedestal 7 When muscle slope surface 9, solving locking key 25 overcomes the biasing force of unlock bias piece 26, the through-hole being detached from the first sliding block 20.First sliding block 20 By the biasing force of the first return unit 23, initial position is come back to, the movement of locking next time can be carried out.

Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or It changes still within the protection scope of the invention.
