Below the course of work of door lock of the present invention is illustrated further.
Fig. 7 a ~ 7c be showing door lock from normal open mode to Normal Shutdown state process the schematic diagram of three states.Be to be understood that, although the door lock with traction element and Lock Part is a preferred embodiment of the present invention, but the door lock without traction element and Lock Part can make door lock return to normal condition very easily equally under improper closed condition, belongs to door lock disclosed by the invention equally.It is below the explanation that the door lock of the present invention without traction element and Lock Part carries out for example.
Fig. 7 a shows door lock when being in open mode.Now hammerlock is in its open position, guide finger 24 be directed to the guiding surface section 112 of surperficial 11a and 11b support (in figure, illustrate only guide surface 11a).Bias component 231 pairs of removable pins 24 apply pulling force forward, but stop because guide finger 24 is directed to surface portion 112 thus rests on guiding surface section 112.
Optionally, guiding surface section 112 outline is arc surface, the axis at its place, center of circle is identical with the axis at rocking arm fixed end 221 place, the guiding surface section 112 with such arc surface at least has following advantage:, two ends due to bias component 231 connect guide finger 24 and fixed end 222 respectively, when not having other foreign components (gate stop or other slender bodies as insertion) to apply external force to hammerlock, guide finger 24 can very stably rest on circular arc guiding surface section 112 optional position, guide finger 24 particular location rested in conductive line surfaces part 112 depends on the size of hammerlock.And when applying external force, the movement of guide finger 24 on guiding surface section 112 is convenient to again in the setting of this arc surface.But should be appreciated that to there is guiding surface section 112 that other shapes extend obliquely also within protection scope of the present invention.
Now 216 be roughly positioned at dead bolt 214 immediately below door lock opening 101 and be positioned at the rear of door lock opening 101, so dead bolt 214 can not be touched when gate stop 31 enters into housing downwards from door lock opening 101 bottom hammerlock.Rocking arm movable end 222 is against the rear end (only showing 217a in figure) of elongated hole 217a and 217b.
Fig. 7 b shows door lock in Fig. 7 a to the state (to answering the door just in pent process) in Normal Shutdown state transition, schematically shows a kind of gate stop 31 simultaneously.Gate stop 31 has the lockhole 312 above bottom 311 and contiguous bottom.Gate stop top 311 contacts the bottom 216 of hammerlock 21, gate stop top 311 applies to try hard to recommend dynamic hammerlock front end 211 downwards and moves down, hammerlock 21 applies power by elongated hole 217 hole wall to rocking arm movable end 222, promote the axis of rocking arm movable end 222 round rocking arm fixed end 221 place in the drawings counterclockwise to rotate, thus promote the axis counterclockwise rotation of hammerlock 21 around rocking arm fixed end 221 place, to make guide finger 24 move up along guiding surface section 112, until exceed the peak b of guiding surface section 112.
Fig. 7 c door lock shown in Fig. 7 b arrives its Normal Shutdown state.Along with gate stop continues to move down, guide finger 24 in Fig. 7 b moves up, after exceeding the peak b of guiding surface section 112, it is directed to surface portion 113 and supports, because now guide finger 24 no longer stops by guiding surface section 112, bias component 231 applies bias force and pulls guide finger 24 to move forward along guiding surface section 113, thus drives hammerlock 21 to move forward, guide finger 24 go ahead mobile until be directed to surface portion 114 stop and be thus parked in α place, turning.So b point is also the critical point of conductive line surfaces part 112 and 113.In the process, under the restriction of rocking arm 22, the dead bolt 214 of hammerlock front end inserts forward gate stop lockhole 312 and is engaged with and promotes gate stop downwards, and such hammerlock 21 arrives fastening position, and door lock is in Normal Shutdown state, and door is finally closed.Because hammerlock 21 moves forward, dead bolt 214 now in the vertical direction is located substantially on immediately below door lock opening 101, interrupts the passage that gate stop 31 passes in and out housing 1.
Accompanying drawing 8a ~ 8c show the door lock shown in Fig. 7 a ~ Fig. 7 c from Normal Shutdown state to open mode process the schematic diagram of three states.
Fig. 8 a shows door lock when being in Normal Shutdown state.Now hammerlock 21 is in its fastening position, and dead bolt 214 inserts gate stop lockhole 312 and is meshed with it.Guide finger 24 is directed to surface portion 113 and supports, and bias component 231 pairs of removable pins 24 apply pulling force forward, but stops owing to being directed to surface portion 114, and guide finger 24 can not move forward the α place, turning being limited at guide surface.
Fig. 8 b shows door lock in Fig. 8 a to the state (process that corresponding Qianmen is being opened) in open mode transition.Gate stop 31 has been pulled upwardly, gate stop upwards applies power in dead bolt 214, hammerlock front end 211 is moved up; rocking arm movable end 222 turns clockwise in the drawings around the axis at rocking arm fixed end 221 place, it makes hammerlock 21 rotate around the axis both clockwise at rocking arm fixed end 221 place to after-applied power in the rear end of hole 217a and 217b.Guide finger 24 along with hammerlock 21 rotation and move backward along guiding surface section 113, until exceed the peak b of guiding surface section 112 backward.Guide finger 24 due to lose guide surface 113 supporting and along guiding surface section 112 slide downward, till gate stop is pulled out completely.In the process, along with hammerlock 21 backward mobile and gate stop 31 move up, dead bolt 214 also moves backward thus departs from and the engaging of gate stop lockhole 312, and dead bolt 214 no longer interrupts the passage that gate stop 31 passes in and out housing 1, gate stop 31 continues to move up, thus can leave door lock housing 1.
Fig. 8 c door lock shown in Fig. 8 b arrives its normal open mode.When guide finger 24 is after guiding surface section 112 slide downward, the bias force that bias component 231 is applied to guide finger 24 makes guide finger 24 compression rest on guiding surface section 112, thus making hammerlock 21 remain on its open position, door lock is in its normal open mode.
Fig. 9 a ~ 9c shows the door lock shown in Fig. 7 a ~ Fig. 7 c and Fig. 8 a ~ Fig. 8 c just can return to normal condition from improper closed condition very easily by the mode of normally closing the door.
Fig. 9 a shows the door lock 100 be under improper closed condition, and hammerlock 21 is in and shown hammerlock fastening position in Fig. 7 c and 8a, but gate stop 31 not as shown in Fig. 7 c and Fig. 8 a engage with dead bolt.On the contrary, dead bolt 214 in the vertical direction is located substantially on immediately below door lock opening 101, has interrupted the passage that gate stop 31 passes in and out housing.The gate stop top 311 entering door lock opening 101 downwards contacts and slope (or radian) 215 above lower compression dead bolt 214.Gate stop is applied to the transverse component F that the downward Lik-Sang of hammerlock 21 becomes to promote hammerlock 21 and move backward by this slope (or radian) 215.
Fig. 9 b shows door lock hammerlock 21 in Fig. 9 a and moves backward under the effect of above-mentioned transverse component F.Specifically, under the effect of above-mentioned transverse component F, hammerlock 21 moves backward, and guide finger 24 moves backward along with hammerlock 21 and moves backward along guiding surface section 113, thus abdicates the passage continuing to move down in permission gate stop top 311.The Design of length of dead bolt 214 is before guide finger 24 moves backward to the peak b of guiding surface section 112, and dead bolt 214 has abdicated the passage allowing gate stop top 311 to continue movement straight down.In the process, also move backward along with hammerlock 21 moves elongated hole 217a and 217b backward, rocking arm movable end 222 moves forward relative to elongated hole.Like this, bias component 232 is elongated, and it produces the power impelling guide finger 24 to reset.In the process, bias component 321 is elongated, and it also produces the power helping guide finger 24 to reset.
Fig. 9 c show gate stop continue to move down make door lock arrive closed condition.Along with dead bolt as Fig. 9 b abdicates the passage that movement is straight down continued on gate stop top 311, dead bolt 214 is crossed on gate stop top 311, after this under the pulling force effect of bias component 231, guide finger 24 moves forward reset along guiding surface section 113, drive hammerlock 21 to move forward, dead bolt 214 moves forward along with the reach of hammerlock thus the gate stop lockhole 312 inserted above gate stop top being engaged with.Hammerlock 21 arrives its fastening position again, and door lock arrives closed condition, and door is normally closed.
Visible above-mentioned Fig. 7, Fig. 8 and Fig. 9 (for simplicity, Fig. 7, Fig. 8, Fig. 9 refers to Fig. 7 a-Fig. 7 c respectively, Fig. 8 a-Fig. 8 c and Fig. 9 a-Fig. 9 c) shown in door lock not only can open and close easily, thus make to be opened and closed normally, and when door lock can be made to be in improper closed condition, as long as by mode of closing the door normally, door lock just can be made to be restored to normal condition, very convenient, eliminate the trouble need sought professional and help.
Forward now Fig. 3 a to, elongated hole 217a and 217b as shown in Figure 3 a extends along the length direction of hammerlock substantially.Elongated hole 217a and 217b profile are not common rectilinear forms, but between elongated hole rear and front end, be formed with downward projection 292.Protruding 292 can be formed in the following manner: the downside of elongated hole 217a and 217b to have from elongated hole rear end obliquely and the front extensions 290 extended forward, this front extensions 290 end to end at from elongated hole front end obliquely and the end of the part 291 that extends back extended back, thus forms downward projection 292.The structure of this elongated hole is also show in Fig. 7, Fig. 8 and Fig. 9.If common rectilinear elongated hole, then find the impact due to frictional force, when normally closing door lock (when namely gate stop inserts); rocking arm can slide into front end from elongated hole rear end; so just may occur that hammerlock just rotates counterclockwise around the axis of guide 24; rocking arm slides in elongated hole, but guide finger 24 is not along the situation that guiding surface section 112 moves upward, and therefore makes door lock to close.And elongated hole 217a and 217b had to lower convexity 292 as shown in Figure 3, then can limit the motion of rocking arm 22 in these cases.Ideally, protruding 292 can make rocking arm movable end 222 can not slide relative to elongated hole 217a and 217b when normal closedown door lock, thus ensure that door lock can be normally closed by inserting gate stop under normal open mode.Even if due to manufacturing tolerance; rocking arm movable end 222 can slide by relative elongated hole 217a and 217b when door lock is normally closed; the part 291 that will be subject to when it slides at most protruding 292 place extending back limits and cannot continue forward slip; still ensure that door lock can normally be closed when gate stop inserts.And the elongated hole of this structure can also ensure under the improper closed condition of door lock; rocking arm movable end 222 can slide smoothly in elongated hole; because in the improper closedown situation of door lock; hammerlock front end 211 is depressed; so the angle that the part 291 that now extends back is formed relative to horizontal direction is less, can not affect rocking arm movable end 222 relative elongated hole forward slip in elongated hole.So elongated hole 217a and 217b of this shape can ensure that door can not move upward along guiding surface section 112 due to above-mentioned guide finger 24 and cause the situation that door lock cannot be closed.
Although Fig. 3 and Fig. 7, elongated hole 217a and 217b shown in Fig. 8 and Fig. 9 is a kind of preferred embodiment, but when being to be understood that the linear elongated hole of ordinary straight allows door lock of the present invention to be subject to the downward power of gate stop equally under improper closed condition, hammerlock 21 also can move as shown in Figure 9 backward, also can solve the technical problem making the door lock of improper closedown recover normal condition easily.Certainly, elongated hole 217a and 217b also can have other shape.
In addition, for the consideration of security standpoint, user wishes that front door for drum-type washing machine can be in the lock state in washing machine running always.Except non-severed roller washing machine power supply makes roller washing machine shut down, even if otherwise in laundry processes front door for drum-type washing machine be applied in outside pulling force, Qianmen can not be opened.In the present invention, further by above-mentioned door lock, installation Lock Part and traction element realize above-mentioned purpose further.
The illustrative examples of a kind of Lock Part disclosed by the invention and traction element is also show in Fig. 2 b.The front portion of Lock Part 25 has the space 252 that can hold hammerlock rear end 212, and space 252 limited by protuberance 255 and 256.Optionally, Lock Part 25 has outwardly directed metallic pin 251, and metallic pin 251 is also gone up and is also provided with elastomeric element 254, and this elastomeric element is such as spring.Further alternative, this metallic pin is arranged on protuberance 256.
Traction element 26 can be spiral coil assembly as shown in Figure 2, can produce magnetic field after energising.When traction element and Lock Part are installed in Rear housing half 1b, the metallic pin 251 being provided with elastomeric element 254 inserts in spiral coil assembly 26.When spiral coil assembly 26 is energized, its magnetic field produced produces tractive force to metallic pin 251, thus traction lock limiting-members 25 moves towards traction element 26, now, the elastomeric element 254 be arranged on metallic pin is produced the bias force contrary with tractive force direction by compression, but the tractive force that magnetic field produces exceedes the bias force that elastomeric element 254 is produced by compression.The magnetic field dissipate when spiral coil assembly 26 stops energising, is now made Lock Part reset by the bias force that the elastomeric element 254 compressed produces.
Figure 10 a is the top view of door lock Rear housing half 1b when washing machine is in non-operating state in Fig. 6 a, and spiral coil assembly 26 no power, Lock Part 25 is in non-locked position, and the metallic pin 251 being provided with elastomeric element 254 inserts in spiral coil assembly 26.As shown in Figure 10 a, now door lock is in open mode and hammerlock 21 is in its open position.The protuberance 255 and 256 of Lock Part 25 lays respectively at the top of hammerlock sidewall 219b and the below of hammerlock sidewall 219a, and the space 252 that protuberance 255 and 256 limits holds hammerlock rear end 212.
Figure 10 b shows the Rear housing half 1b in Figure 10 a, spiral coil assembly 26 no power, Lock Part 25 is in non-locked position, but now door lock is transformed into closed condition from the open mode shown in Figure 10 a, and hammerlock 21 also arrives its fastening position from the open position Figure 10 a.As shown in fig. lob, space 252 is left because hammerlock 21 moves forward to its fastening position in hammerlock rear end 212.
According to Figure 10 a and Figure 10 b, when Lock Part is in non-locked position, hammerlock 21 can realize Fig. 7, shown in Fig. 8 and Fig. 9 at its open position and fastening position any switching laws, namely the Qianmen of washing machine can be opened and closed freely.
Figure 10 c shows the Rear housing half 1b in Figure 10 b, and compared with the Rear housing half 1b in Figure 10 b, the Lock Part 25 of the door lock that its difference is in Figure 10 c is in latched position, door lock state when its corresponding washing machine runs.Now spiral coil assembly 26 is energized, spiral coil assembly can produce magnetic field as previously mentioned, the metallic pin 251 of tractive force meeting traction lock limiting-members 25 that it produces moves down, Lock Part 25 is moved down into latched position from the non-locked position shown in Figure 10 a and 10b thereupon, protuberance 255 moves to the rear of hammerlock rear end 212, protuberance 255 end props up hammerlock rear end 212, therefore hammerlock 21 cannot get back to its open position, door lock cannot be opened, and this just ensures that washing machine front door cannot be opened when washing machine operates after shutting.
Should be appreciated that the structure of Lock Part 25 can have other form.As protuberance 256 just can be omitted, now metallic pin 251 can be installed in other parts of Lock Part 25, only needs Lock Part to have protuberance 255 and holds the space 252 of hammerlock rear end.
Again such as, when Lock Part 25 is moved down into latched position, protuberance 255 might not contact hammerlock rear end 212, even if having space between protuberance 255 end and hammerlock rear end, as long as this space is moved after being not enough to make hammerlock 21 abdicate the passage that gate stop 311 exits door lock.
The door lock having installed Lock Part and traction element has the advantage that can ensure that door cannot be opened when washing machine operates.
And, door latch structure of the present invention makes hammerlock length direction and hammerlock move forward and backward direction and gate stop passes in and out direction perpendicular, thus not only solve how easily improper closedown door lock to be recovered normal problem, and this structure can not increase the thickness being provided with this door latch device.Above-mentioned advantage will be example embodiment clearly by the following door lock be arranged on a roller washing machine front portion.
Figure 11 a shows the schematic diagram that has the roller washing machine front portion 800 of door lock disclosed by the invention.Roller washing machine front portion has the opening picking and placeing clothing, and what usual opening was placed in the middle is arranged on roller washing machine front portion.Roller washing machine is anterior is provided with door lock 100 disclosed by the invention closing on opening part.Door lock opening 101 is outwards arranged facing to roller washing machine is anterior, and the length direction of door lock hammerlock 21 (not shown) is parallel to the plane at the anterior place of roller washing machine.
Figure 11 b is the top view of the roller washing machine having installed door lock 100 in Figure 11 a.Roller washing machine has Qianmen 300, and the side at Qianmen 300 is pivotable is arranged on roller washing machine front portion, and Qianmen 300 opposite side is provided with gate stop 31.When Qianmen is closed, gate stop 31 inserts in door lock opening 101 with the direction perpendicular to door lock opening 101, thus door lock 100 is closed as disclosed in manual is above-mentioned; When Qianmen open close time, gate stop 31 is to leave in door lock opening 101 perpendicular to the direction of door lock opening 101, thus door lock is opened as disclosed in manual is above-mentioned.Along with gate stop 31 inserts and leave door lock opening 101, the hammerlock 21 in door lock can seesaw along the direction (being namely parallel to the plane at the anterior place of roller washing machine) passing in and out door lock opening perpendicular to gate stop 31.Door lock housing is flat on the thickness direction of roller washing machine.So the length direction of door lock of the present invention its hammerlock after mounting can not increase the thickness of roller washing machine front portion, and the direction that seesaws of hammerlock also can not increase the thickness of roller washing machine front portion.
Door lock 100 can be arranged in such a way: the length direction of door lock hammerlock 21 is parallel to short transverse or the length direction of roller washing machine, and the direction that such hammerlock moves forward and backward is just parallel with the short transverse of roller washing machine or length direction.But should be appreciated that if the plane making the length direction of the hammerlock 21 of door lock of the present invention be parallel to the anterior place of roller washing machine is arranged, the length direction of hammerlock 21 also can become angle of slope with roller washing machine length direction or short transverse.Because now, the movable direction of hammerlock 21 is parallel to the plane (namely perpendicular to the turnover direction of gate stop) at the anterior place of roller washing machine equally.
So door lock of the present invention not only solves the problem conveniently cannot recovering normal condition under door lock in prior art is in improper closed condition, and its structure can not increase the thickness of roller washing machine front portion, naturally also would not increase the thickness of roller washing machine entirety because of the design of door lock, contribute to the thin design realizing roller washing machine.
