Accompanying drawing explanation
In the process of the detailed description provided by means of only non-limiting example with reference to accompanying drawing below, the features and advantages of the present invention will become clear.
Fig. 1 is the stereogram according to door lock of the present invention;
Fig. 2 is the stereogram of the part indicated by arrow II in FIG; And
Fig. 3, Fig. 4 and Fig. 5 are the view of arrow III, IV and V according to Fig. 2 respectively.
Detailed description of the invention
With reference to Fig. 1, numeral 10 instruction is according to the door lock for home appliance of the present invention.Door lock 10 comprises lock cell 12 and electric control unit 14.Lock cell 12 and electric control unit 14 can be two separate units separated from one another being provided with respective housing 16,18.Alternatively, lock cell 12 and electric control unit 14 can be integrated in single housing.
Lock cell 12 comprises the cam 20 that can rotate relative to housing 16 around the first pivot center A.Cam 20 can rotate at the spaced winding axis A of lock position and off-position.
Cam 20 is associated with the first spring 22.Spring 22 has bi-stable function.When the door of equipment is in an open position, cam 20 is pushed into off-position by spring 22.When the door of equipment is closed, cam 20 is pushed into lock position by spring 22.
Cam 20 has hook portion 24, and this hook portion 24 is intended to engage hook 26, and this hook 26 is carried by the door (not shown) of home appliance.In operation, in the closing process of door, hook 26 stretches in housing 16 through the opening of housing 16, and engages (engage) with the hook portion 24 on the cam 20 being in off-position.Particularly, hook 26 is provided with door stop hole 38, forms gate stop crossbeam 39 above door stop hole 38, forms cam chamber 37 in the front portion of cam 20.When the hook portion 24 of hook 26 and cam 20 engages, gate stop crossbeam 39 is moved in cam chamber 37, engages each other to be formed.Thus cam 20 is turned to lock position around axis A from off-position by the insertion campaign of hook 26.When the door closes, cam 20 is in the lock position shown in Fig. 1 to Fig. 5.
Door lock 10 comprises sliding part 28, and this sliding part 28 can rotate relative to housing 16 around the second pivot center B, this second pivot center B relative to the first pivot center A with 90 ° of orientations.Sliding part 28 can rotate at the spaced winding second pivot center B of latched position and non-locked position.Second spring 30 pushes sliding part 28 to latched position.With reference to Fig. 2 to Fig. 5, sliding part 28 has the first sticking department 32 and the second sticking department 34 being arranged on relative both sides relative to the second pivot center B.First sticking department 32 is intended to contact cam 20 so that cam 20 is locked in lock position.Second sticking department 34 is intended to contact stop pin 36.Stop pin 36 is arranged in electric control unit 14, and can move in the rectilinear direction being parallel to the second pivot center B between non-locked position and latched position.Stop pin 36 is controlled by the electromagnetic actuators (not shown) being arranged in electric control unit 14.More specifically, on stop pin 36, apply electromagnetic force by (under the control of electric control unit 14), stop pin 36 can under the driving of electromagnetic actuators (not shown) along the rectilinear direction (as shown in Fig. 2 arrow 41 direction) being parallel to the second pivot center B between non-locked position and latched position up and down (or in a reciprocal manner) mobile.
Structure and the operation of electric control unit 14 is describe in detail in document WO2013181289.For the purposes of the present invention, notice that electromagnetic actuators controls the motion of stop pin 36 between non-locked position and latched position just enough.When pin 36 is in non-locked position, vernier (cursor) 28 freely rotates around the second pivot center B.Therefore, cam 20 freely rotates around the first pivot center A.When stop pin 36 is in latched position, sliding part 28 is locked in latched position.In this case, the first sticking department 32 and the cam 20 of sliding part 28 interfere the contact of (prevention) property, and cam 20 is locked in lock position.
With reference to Fig. 5, the first sticking department 32 is positioned at the distance R1 place apart from the second pivot center B.Second sticking department 34 is positioned at the distance R2 place apart from the second pivot center B.Distance R1 and R2 measures according to the central point of respective sticking department 32,34.
When the door of equipment is in the closed position, the power acted on hook 26 is indicated by F in figure 3.Power F produces power F1 on the first sticking department 32 of sliding part 28.Power F1 is balanced by the power F2 acted on the second sticking department 34.The moment produced by two power F1 and F2 compensates one another, and following relationship is set up: F1 × R1=F2 × R2.According to favorable characteristics of the present invention, distance R2 is greater than distance R1.Therefore, the power F2 putting on the second sticking department 34 from stop pin 36 is less than the power F1 being put on the first sticking department 32 by cam 20.
With reference to Fig. 4, what indicated by F3 is the power being put on stop pin 36 by electromagnetic actuators, so that stop pin 36 is moved to non-locked position from latched position.Power F2 allows to reduce the power F3 unlocked required for sliding part 28 relative to the fact that power F1 reduces.
The reduction of the power F3 of unblock required for door lock 10 unlocks when making door lock 10 also can there is pressure due to the compressive load in the cylinder of machine on door.
Therefore, even if solution according to the present invention makes also can discharge door lock under the most critical condition, wherein, the risk with the door locked of closing is kept even if also to emit when needing to open according to the door lock of prior art.
It should be noted that the invention configuration of parts in a structure of the in-vention provides a kind of suitable technical solution on the whole, this solution may be provided in some technological merit in door lock.Such as, driving force from electromagnetic actuators around the cam 20 of the first pivot center A rotation, the sliding part 28 that can rotate around the second pivot center B and can not only can be applied to stop pin 36 along the stop pin 36 of the rectilinear direction movement being parallel to the second pivot center B by configuration effectively, and it is that configuration performs difference in functionality and is arranged on the suitable method of the moving-member (comprising cam 20, sliding part 28 and stop pin 36) in the confined space.This configuration improves the feasibility manufacturing this door lock.
In addition, be arranged on the relative both sides of sliding part 28 by the first sticking department 32 is rotated B with the second sticking department 34 relative to the second axis, and by the first sticking department 32 being configured to contact cam 20 and the second sticking department 34 is configured to contact described stop pin 36, technical solution of the present invention can improve the effect driving force from electromagnetic actuators being applied to stop pin 36 further, and improves the feasibility manufacturing this door lock.
It should be noted that this technical solution can have other technological merit, these technological merits should not be limited to those technological merits specifically described in this application.
Certainly, when not affecting principle of the present invention, wide in range change can be carried out relative to described with structure detail that is that illustrate and embodiment to structure detail and embodiment, and not departing from scope of the present invention as defined by the appended claims.
