Boss, hitch body 17-5 and the groove type hole or barb of the lock body have the lateral boss corresponding.
Illustrate the use state of the present invention below：
One, door opening states
Washing machine door opening state keeper is not inserted into keyhole 1-1, and it is lower in reset shape that lock body 17 hangs the effect of torsional spring 18 outside
State, referring to 17 non-pivotal orientation of Figure 19 lock bodies；The return in the case where connection flat spring 35 acts on of connecting plate 29 is in right position state, even
The inclined-plane boss 29-2 of fishplate bar left end is in jacks up state by movable contact spring 2 11, and two contact 11-1 of movable contact spring is touched with coil terminals one
Point 4-1 leaves, meanwhile, operation panel 16 is in left position state, and the shifting block 16-3 of operation panel lower part is in jacks up shape by movable contact spring 1
State, one contact 9-1 of movable contact spring leave with one contact 12-1 of terminal, see Figure 12 and referring to figure Figure 10.
Two, shutdown states
Keeper is inserted into keyhole 1-1 at closing time, and referring to Figure 19, keeper head pushes the U-shaped recess lower left side of lock body 17, makes
Lock body is pivoted to diagram F directions, the U-shaped recess of lock body is in vertical state when keeper is inserted in place, at this time lock body
Hitch body 17-5 buckles into the groove type hole of keeper or barb-shaped lateral boss completely, while is turned over the outer outstanding torsional spring 18 of lock body cooperation
Turn, the spring coil of outer outstanding torsional spring is by being pressed on lock body, and lock body by enough pressure, hold by the hitch body that keeper is locked body；Lock
When determining body and being pivoted in door closing procedure, push the inclined convex top 29-1 of 29 plate right end of connecting plate, connecting plate move to left after in left position
State, the inclined-plane boss 29-2 of connecting plate left end, which is in, leaves 2 11 state of movable contact spring, two contact 11-1 of movable contact spring and coil-end
One contact 4-1 of son is contacted, and the conducting of door signal circuit provides door signal.
Three, shutdown back pullout (BPO)s
Under shutdown state, apply an outside pulling force to keeper, the hitch body 17-5 that keeper holds lock body is pulled outwardly, and is locked
Body overcomes the tension of outer outstanding torsional spring 18, is pivoted to the negative direction of F directions shown in Figure 19, when pivoting in place, keeper is from the U of lock body
Type recess is deviate from, while outstanding torsional spring overturning, spring coil body leave lock body outside.
Lock-out state after four, shutdowns
Under shutdown state, give electromagnetic coil 6 one on-off electric pulse, operation panel 16 is together with piston 15 in return spring two
It is moved to right under 22 effects, operation panel is in right position state, and the backing pin 16-2 for operating prelaminar part is inserted into the recess portion 17-3 of lock body 17, resistance
Only lock body is turned round, and the U-shaped recess of lock body is fixed in the vertical state, keeps keeper that cannot deviate from from lock body；Together
When, after operation panel moves to right, the shifting block 16-3 of operation panel lower part leaves the curved arc end of movable contact spring 1, one contact 9-1 of movable contact spring and end
One contact 12-1 of son is contacted, and signal circuit of locking a door conducting provides signal of locking a door.
Under lock-out state, even if applying an outside pulling force to keeper, since the backing pin 16-2 of operation panel blocks lock body
Rotation, lock body cannot pivot, and keeper cannot be deviate from from the U-shaped recess of lock body.
Five, lock-out states release
Give electromagnetic coil one on-off electric pulse, 15 pull operation plate 16 of piston moves to left, and operation panel is in left position state, behaviour
The backing pin for making plate leaves lock body, keeper is given to apply an outside pulling force at this time, after lock body pivots, keeper is from the U-shaped of lock body
Recess is deviate from；Meanwhile the shifting block 16-3 of operation panel move to left after jack up movable contact spring 1, one contact 9-1 of movable contact spring and one contact of terminal
12-1 leaves, signal relief of locking a door.
The manual releasing of six, lock-out states
Under lock-out state, apply external force and pull downward on connector 28, the manual plate 20 that releases being connected with connector is to moving to left
Dynamic (dextrad of Fig. 4, the left-hand of Figure 12), since the cylinder 16-4 of operation panel is located at the elongated hole 20-1 of releasing plate manually, manually
Plate pull operation plate is released to be moved to the left, the backing pin of operation panel leaves lock body, while the shifting block of operation panel jacks up movable contact spring one,
Apply outside pulling force to keeper, keeper is deviate from from the U-shaped recess of lock body, while locking signal releases.
Seven, close the door and locking electric connection structure
As shown in figure 21, it is corresponding with the contact of the contact coil terminal 1 for the movable contact spring 2 11 that terminal 28 connects, it forms
Switch one, the contact of movable contact spring 1 is corresponding with the contact of terminal 1, forms switch two, terminal 3 14 and two electricity of coil terminals
Connection.After shutdown, with associated one state of control panel circuit detection switch of the present invention, confirm that it is to provide door signal to be closed, so
Apply AC220V pulse voltages, after electromagnetic coil 6 is by pulse current, operation panel 16 between terminal 28 and terminal 3 14 afterwards
Action, the backing pin 16-2 of operation panel is inserted into the recess portion 17-3 of lock body and the shifting block 16-3 of operation panel lower part leaves movable contact spring one
9, the contact of movable contact spring 1 and the contact of terminal 1, signal circuit of locking a door conducting provide signal of locking a door.
The present invention is equipped with electromagnetic coil and its associated piston, and equipped with the operation panel being connected with piston, operation panel has gear
Pin, shifting block, positioning/reseting groove platform structure and cylinder, the present invention set by the lock body for being connected with resetting spring have U-shaped recess and
Hitch body, the present invention are equipped with the connecting plate with return spring two, and there is connecting plate inclined convex top and inclined-plane boss, the present invention to set
There are terminal one, terminal two and terminal three, movable contact spring one and movable contact spring two, one contact of movable contact spring and terminal one are connected on terminal two
Contact corresponds to, and the contact of movable contact spring two is corresponding with one contact of coil terminals, and the mobile of operation panel can pivot lock body blocking
Or barrier effect being released, and the shifting block of operation panel can jack up movable contact spring one or release this jack-up, the mobile of connecting plate can jack up
Movable contact spring two releases this jack-up, and the present invention is connected with PTC thermistor between terminal three and coil terminals two, the present invention
It is additionally provided with and releases plate manually, under lock-out state electromagnetic coil not working condition, can unlock state manually.Therefore present invention tool
It is functional comprehensively, construction it is relatively easy, manufacture it is at low cost, it is small the features such as；The present invention provides door signal, locks and provide
It locks a door only three conductive paths in the electric connection structure of signal, replaces existing six terminal with three terminals, connection can be reduced and connect
