Bi-stable function.When the door of equipment is in an open position, cam is pushed into releasing position by spring.When the door of equipment is closed
When, cam is pushed into lock position by spring.When being protruded into the opening 14 of door when hook because of door closing, the joint portion of cam 16
18 engage and cam 16 around axis A turns to lock position from releasing position with hook.
Door lock 10 includes sliding part 20, which can rotate around second rotation axis B relative to shell 12, this second
Pivot center B is orientated relative to first rotation axis A with 90 °.Sliding part 20 can be in the spaced winding of latched position and non-locked position
Axis B rotation.Sliding part 20 is elastically pushed to latched position by spring 22.Sliding part 20 has relative to second rotation axis B
The first sticking department 24 and the second sticking department 26 of opposite sides are set.First sticking department 24 is intended to contact cam 16 with by cam
16 are locked in lock position.
Second sticking department 26 of sliding part 20 is designed to contact locking pin 28.Locking pin 28 can be parallel to the second rotation axis
It moves, and can be moved between releasing position and latched position on the rectilinear direction C of line B.When 28 engaging slide part of locking pin
When 20 the second sticking department 26, sliding part 20 is locked in latched position.Locking pin 28 by electromagnetic actuators (not shown) with
Mode described in WO2013181289 controls.
Door lock 10 includes the door sensing device 30 for being adapted to detect for the open/close state of door.Door sensing device 30 is sensed including door
Pin 32, lag element 34 and elastic element 36.Door sensing pin 32 in opening position and can close between a position by double-head arrow D
It is moved on indicated direction.Door sensing pin 32 cooperates with the door sensing circuit (not shown) described in WO2013181289.
Door sensing pin 32 is flexibly pushed to contact with lag element 34.
Lag element 34 is carried by sliding part 20 and can be moved along the direction F perpendicular to direction D relative to sliding part 20,
Door sensing pin 32 can D movement in the direction.Lag element 34 can be mobile relative to sliding part 20 between the first and second positions.
Elastic element 36 is arranged between lag element 34 and sliding part 20, and will be late by element 34 and be elastically pushed to first position,
The elastic element 36 can be for example made of spiral compression spring.Sliding part 20 has seat 38, and lag element 34 is along direction F in the seat
It is slidably guided in 38.
Referring to Fig. 2 to Fig. 8, lag element 34 includes plane 40；Terminate in the slope 42 in plane 40；And it is located at plane
Step 44 between 40 and slope 42.
The operation of door lock 10 according to the present invention is described to Fig. 8 referring now to Fig. 2.
Fig. 2 shows the door locks 10 in the construction that appliance doors are opened.In this configuration, cam 16 is in releasing position,
And sliding part 20 is in non-locked position.Cam 16 is freely rotated around first rotation axis A.Lag element 34 is pushed away by spring 36
To first position.Locking pin 28 is in non-locked position and door sensing pin 32 is contacted with the plane 40 of lag element 34 and position
In opening position.It is to disconnect with door sensing 32 associated sensing circuits of pin.
Fig. 3 shows the position of the door lock 10 in door closing process.Gate stop engaged with the joint portion 18 of cam 16 and
Side is upwards about axis A rotation cam 16 as indicated by arrow G.Sliding part 20 is under the action of the power of spring 22 along by arrow H
Indicated direction is rotated around second rotation axis B.Spring 36 will be late by element 34 and be maintained at first position.Door sensing pin 32 is protected
It holds and is contacted with the plane 40 of lag element 34 and door sensing circuit remains open.
Fig. 4 is shown in the position for the door lock 10 for closing a position.Cam 16 is in lock position.Sliding part 20 is in locking
Position.In the position, door sensing pin 32 crosses the step 44 of lag element and immediately on the direction as indicated by arrow K from opening
Door position, which is shifted to, closes a position.Door sensing pin 32 is contacted with the relatively lower part on the slope 42 of lag element 34.Door sensing pin 32 exists
Door sensing circuit is closed by the movement on the K of direction.This moment, the electromagnetic actuators of control door sensing pin 32 can be started.
As shown in figure 5, electromagnetic actuators move locking pin 28 on the direction indicated by arrow L.Locking pin 28 moves on to lock
Positioning is set, in the latched position, the second sticking department 26 of 28 engaging slide part 20 of locking pin.Therefore, sliding part 20 is locked in
Latched position.Cam 16 is locked in lock position and the hook of door and cannot separate with door lock.
Referring to Fig. 6, at the end of the working cycles of machine, electromagnetic actuators are in the direction as indicated by the arrow M in Fig. 6
On locking pin 28 shifted into non-locked position.This moment, sliding part 20 is unlocked and cam 6 can be rotated towards releasing position.
As shown in fig. 7, when the door is open, cam 16 turns in the side as indicated by arrow N upwards about first rotation axis A
It is dynamic.Cam 16 rotates sliding part 20 upwards about second rotation axis B in the side as indicated by arrow P.When sliding part 20 is in direction P
On around axis B rotation when, door senses the step 34 that pin 32 engages lag element 34, and will be late by element 34 and push the second position to,
Thus compressed spring 36.In sliding part 20 in the rotation process on the P of direction, door sensing pin 32 is connected on slope 42.Men Chuan
Sense pin 32 moves up and when door sensing pin 32 reaches opening position, and door sensing circuit disconnects.
Following angular position in sliding part 20 occurs for the disconnection of door sensing circuit, which is different from that door sensing occurs
The Angle Position of the sliding part 20 of closing of circuit.In this way, determining the position of the vernier 20 of door sensing circuit closure and determining that door passes
There is lag between the position for the vernier 20 that inductive circuit disconnects.
Referring to Fig. 8, when the door is open, cam 16 is back to releasing position and sliding part 20 returns to non-locked position.
Door sensing pin 32 engages the plane 40 of lag element 34, and spring 36 will be late by element 34 back to first position.
In the case where not departing from the scope of the present invention as defined by the appended claims, can to the present invention relative to
Those of described and illustrated example carries out various modifications.For example, sliding part 20 can be mobile in rectilinear direction rather than around axis B
Pivotally move.Lag element 34 can be moved relative to sliding part 20 along direction of a curve, rather than linearly
It is mobile.
