Description
Technical field
The present invention relates to the locking and unlocking device of a kind of the locking and unlocking device of door lock, particularly roller washing machine door lock.
Background technology
The locking and unlocking device of the tumbling-box washing machine gate of present production and selling, i.e. door interlock switch design originally derives from European countries.The simple whole signal of this washing machine and door lock thereof as shown in Figure 1, has cylinder b in body a the inside, cylinder oral area e is positioned at the body front and is used for washings and puts into and take out, the matrix front is provided with the door body g that opens and closes the cylinder oral area, door body g is provided with gate stop f, have opening d on the perpendicular wall in the front of body, gate stop f is locked in the body opening d.
The opening of door lock assembly c is chimeric with the opening of door body, and gate stop f enters behind the opening because the rotation of gate stop self promotes slide plate slides to the right, and makes the lock opening of slide plate corresponding with the top of lock slider.
Clamping block is subjected to external force when the slide plate direction moves, and lock slider just is embedded in the opening the inside.Then because lock slider be positioned in slide plate opening, can not slide slide plate as desiring the gate stop of direction rotation to the left and right this moment.Correspondingly gate stop is lockable because of not rotating.
The action of above-mentioned lock slider is controlled by bimetal leaf.The bimetal leaf action forces lock slider to move, and under the energising hold mode, bimetal leaf keeps upset, and lock slider keeps embedding slide block, and the gate stop locking keeps; Bimetal leaf cooling during outage, the upset that resets, lock slider withdraws from the opening of slide plate, and the mobile constraint of slide plate on left and right directions is disengaged, and the locking of gate stop is disengaged.
Because above-mentioned lock out action is to drive by the deformation of bimetal leaf heating power, latch-release then must could be realized after bimetal leaf outage cooling, thereby produce following problems:
1) just can make lock slider enter latched position after the bimetal leaf heating is deformed to a certain degree, this needs the regular hour;
2) bimetal leaf cooling back lock slider will reset, so when the washing machine abnormal power-down, the locking of door body will be removed, if abnormal power-down in the program running, then water in the washing machine and washings may incessantly flow out because of door closes;
3) program running begins the back user and wishes interrupt routine, beats that opening door body is appended or when taking out clothing, must wait for several minutes and just can open;
4) program running at the end owing to will wait for several minutes and could beat opening door body and take out washings, is equivalent to prolong washing cycle.
In order to address the above problem, household electrical appliances manufacturing firm in various countries' has carried out some researchs, has proposed some solutions.Wherein the operating principle of the door interlock switch that proposes of the invention of publication number CN1160103C is: open and close the door body of machine body peristome, the rotation by gate stop makes described door body be in closed condition; Energising makes mobile's action to solenoid by outer operation, makes blocking device keep lock-out state.Its shortcoming is:
1) gate stop must insert certain depth, surpasses under the situation of blocking device thickness, and blocking device could be lived hook lock, and door may not can't lock when user's operation was not noted;
Provide the signal of locking a door, this invention can not utilize the action of gate stop that the signal of locking a door is provided when 2) needing to lock a door in the washing machine security control.
The operating principle of the door interlock switch of publication number CN1536139A is in addition: the mid portion of gate stop has the recessed structures of symmetry with respect to the head both sides, when gate stop vertically inserts door lock assembly, the lock body that the door lock assembly both sides are had is slided to both sides by the extruding of gate stop, when the recess access door locking device of gate stop, lock body is subjected to the compression of spring and sticks into the recessed structures of gate stop; When spurring the door body again under this state, the inclined-plane compressing lock body of the recess of gate stop is to the both sides slip and deviate from door interlock switch.During by electromagnetic coil energising/outage, slide mass produces displacement under lock-out state, and the part of slide mass moves to the both sides of aforementioned lock body, makes lock body not move and the gate stop locking is kept to both sides.During energising/outage,, slide mass make the lock body locking keep removing once more thereby being returned to the home position again.
Be characterized in relying on the pressure of the spring on the fast both sides of locking to make gate stop to lock after gate stop inserts door interlock switch, because door sealing needs certain pressure, and in order to prevent that gate stop from deviating from easily, the strength of spring needs bigger, corresponding angle from the operator needs bigger pressure when being pressed into gate stop, also needs bigger pulling force when opening gate stop simultaneously.These two power all need to reach more than several kilograms usually, so there is defective in the structure of this invention aspect operability.
The application number that applicant proposes is that the operating principle of the invention of CN03178598.0 is when being gate stop access door lock-switch, rely on the rotation of gate stop to make gate stop hook the door lock matrix, reach the locking purpose, by the action of electromagnetic coil, the back that makes slide mass be inserted into gate stop realizes that locking keeps; Close the microswitch conducting of the feasible inside of snap-fastener on the action compressing door interlock switch by the pass of door body.But this structure is pinned the snap-fastener of door interlock switch outside such as child, and door interlock switch also can provide normal locking and locking inhibit signal, and washing machine can be intake and rotational action normally, thereby produces problems such as spilling water and personal injury.
Summary of the invention
Present described door of washing machine is latched in or locking/uncaging time is long in order to solve, or operation is harder, or problem such as safety is not enough, electromagnetic door lock of the present invention is proposed for this reason, the locking of this door lock/unblank easily and fast, not hard, the locking that washing machine also can keep a body when abnormal power-down occurring when washing prevents that washings and water from flowing out; Optimal way of the present invention can provide and close gate signal, locking signal is used for washing procedure of washing machine control; The present invention can also be accustomed to needs according to the user and realize making things convenient for left hand to close the door and open and close door lock or the right hand and close the door and open and close door lock.
