The place ahead that door 50 can be located at cylinder 40 is to be used for that clothing is put into cylinder/take out from cylinder.Usually, door 50 is installed to a side of casing 20 so that can opening/closing, and is preferably such that a side of door 50 is rotatably fixed to hinge 53 etc.In this case, preferably, when door 50 opening/closings, a relative side such as the part with being fixed to hinge 53 grades of door 50 is secured to casing 20/ and throws off from casing 20.

With reference to figure 1,, can have to rear side promptly along the outstanding breech lock 51 of the internal direction of casing 20 at the rear wall place of door 50.When door 50 when being fixed to the described partial rotation of hinge 53 grades, can utilize the breech lock 51 that optionally engages with casing 20 to realize an opening/closing of 50.

Simultaneously, preferably, casing 20 has and is used to make it possible to the breech lock door switch assembly 10 of door 50 51.That is, in the situation that door 50 is closed, door switch assembly 10 is connected to breech lock 51 with fastening door 50, and if expect to open door 50, thereby then door switch assembly 10 is disconnected from breech lock 51 so that door 50 rotations are opened.

Door switch assembly 10 has the patchhole 610 that is used for inserting therein breech lock.Door switch assembly 10 is installed into makes this patchhole be exposed to the place ahead of casing 20, and other parts of door switch assembly 10 are positioned at the inboard of casing 20.For example, if patchhole 610 forms in the shell 600 of door switch assembly 10, then preferably, only patchhole 610 parts are exposed to the outside of casing 20 by the front portion of casing 20, and other parts are positioned at casing 20.This is in order to consider the aesthetic property of washing machine, and is not subjected to external environment influence for shutter switch module 10.

As parts of door switch assembly 10,, button 110 can be located at casing 20 for the user applies active force to remove the lock-out state of door.Preferably, button 110 is located at the upside of casing 20, and more preferably is located at a side of the control panel 30 of the great majority operation that realizes the user herein.

In view of the above, the user in addition can be with a wet finger by easily removing the lock-out state of door by being pressed in the button 110 on the control panel 30, and need not sit down or squat.With it side by side, can so design, make that by using user's the active force of pushing button 110, not only the releasing of locked door condition but also door opens all and can realize.Therefore, because only be used for rotating further the required active force of having opened of door by applying, the user just can fully open door, so can reduce user's effort intensity, this will describe in detail afterwards.

Simultaneously, with reference to figure 1, can turn up the soil at interval with shell 600 button 110 is set.On the inboard of shell 600, have and be used for by restriction breech lock 51 and the mechanism of door.Therefore, need be used for and to be applied to the device of the force transmission of button 110 to this mechanism of shell.As this transfer device, cable 200 shown in Figure 1.Cable 200 is used for transfer function power between the mechanism of button 110 spaced apart from each other and shell 600.

To describe door switch assembly 10 in detail with reference to figure 2.The perspective view of door switch assembly 10 when the shell that Fig. 2 is shown in the door switch assembly is opened, in the door closing state in Fig. 1.

Door switch assembly 10 can comprise the opening operation unit 100 that is used for removing by user's operation the lock-out state of door.Opening operation unit 100 can not only be used to remove the lock-out state of door, but also is used for partly opening door.User's operation can mean and manually applies active force.In further detail, user's operation can mean and applies the change in location of active force with some members of causing opening operation unit 100.

Door switch assembly 10 can be included in opens the switch element 300 that door was mechanically interlocked with the operation of opening operation unit 100 at 50 o'clock.

Mechanical interlocking means that the parts of opening operation unit 100 and switch element 300 are interconnected so that can realize the interlocking motion.That is, mechanical interlocking means that the active force that applies by opening operation unit 100 mechanically is delivered to switch element 300, and by using by the active force that so is delivered to this, switch element 300 can mechanically be opened door 50.Therefore, except the user be used to operate the active force of opening operation unit 100, need not active force such as electromagnetic force in order to partly to open door.

Therefore because can be by using a kind of mechanical system door 50, thereby with in correlation technique by using electromagnetic force door 50 to compare, make it possible to the simplification system, so can improve the life-span of door switch assembly.

To describe opening operation unit 100 in detail.

Opening operation unit 100 is to open in the situation of door 50 unit by user's operation in user expectation.At 100 places, opening operation unit, the active force that is applied by the user is passed to switch element 300.As preceding description ground, preferably, control panel 30 is located in opening operation unit 100.

Can stipulate that the active force that operation produced by the user is passed to switch element 300, this is because this active force has changed the position of specific features.

Opening operation unit 100 can comprise button 110 (seeing Fig. 1 and Fig. 5), thereby the outside that this button 110 is located at control panel 50 makes individual subscriber to apply active force from the outside of control panel 50.The direction of pressing force that opening operation unit 100 can also comprise the slide block 130 of an end that is used for fixing cable 200 and be used to change button 110 is with the lever of this force transmission to slide block 130.

To describe opening operation unit 100 in detail with reference to figure 5 to 7.

Opening operation unit 100 receives user's operation.Therefore, for switch element 300 can move with the active force that operation produced by the user with interlocking, opening operation unit 100 causes the change in location of cable 20 by using this active force, to move the switch elements with opening operation unit 100 interlockings.

In this case, preferably, opening operation unit 100 comprises the button 110 that is used for the user and active force put on door switch assembly 10 from the outside of door switch assembly 10, is used for carrying out the lever 120 of rotation and the slide block 130 that is used for moving up and down along with the rotation of lever along with the motion of button 110.That is, basically, at 100 places, opening operation unit, the active force that applies owing to the user rotates change in location (change in location of lever 120), and owing to this position of rotation changes linear position variation (change in location of slide block 130) takes place.Certainly, can change (change in location of button 110) owing to linear position originally and rotate change in location.

With reference to figure 5, preferably, thereby the place ahead that a side of button 110 is exposed to casing 20 when the individual subscriber intention is opened door 50, the user can apply active force from the outside of casing 20.

Supporting leg 111 can be located at the rear of button 110, thereby makes that the user can be with the force transmission that applied by the user to the lever 120 of being located at button 110 rears.At the rear of button 110, elastic component 111a can be set, thereby be used for along with the user applies active force and realizes strain.In view of the above, preferably, if remove the active force that is applied by the user, then button 110 is designed to utilize the restoring force of elastic component and turns back to initial position.

Simultaneously, lever 120 can be installed into lever shaft 121 rotations in the hole 151 that can be centered around in the opening operation cell enclosure 150.Preferably, lever shaft 121 is positioned on the supporting leg 111 and is vertical with supporting leg 111.Preferably, lever 120 has

Shape, and lever shaft 121 is located at the edge part office of lever 120.In view of the above, if the supporting leg 111 of button 110 along an end of horizontal direction extrusion lever 120, then lever 120 is around lever shaft 121 rotations.In this case, as shown in FIG. 5, the other end of lever 120 moves up, thereby forms curve.

Therefore, button is designed to realize linear movement, and the linear movement of button is converted to by lever and rotatablely moves.According to this viewpoint, the button 110 among Fig. 5 can be pulled the button of type and be replaced, rather than pushes the button of type.In this case, with above identical, if the lever among Fig. 5 120 is squeezed, then lever rotation, thus the other end of lever moves up, to form curve.

At the rear of lever 120, be connected to lever 120 and realize the slide block 130 that moves along with the rotation of lever 120 thereby have.In this case, slide block 130 can be along the vertical path movement in the guiding piece on the madial wall of being located at shell 150 140.

With reference to figure 5, lever 120 has the insertion portion 123 that is used to place slide block 130 in the rear portion, and slide block 130 has the insertion groove 131 that is used for receiving therein insertion portion 123.

In this case, in order to reduce the interference when slide block 130 moves up and down owing to the rotation of lever 120, this insertion portion can be bent, and preferably can have circular cross section.

Preferably, insertion groove 131 has the open lower side 131a of being convenient to insert insertion portion 123 in insertion groove 131 and being rounded.Yet preferably, the upper surface 131b and the lower surface 131c of insertion groove 131 are smooth, thereby alleviate interference or friction with insertion portion 123.Because insertion portion 123 is not vertically but upwards moves curve plotting.That is, because insertion portion 123 is configured to when lever 120 rotation in insertion groove 131 to front slide, so be necessary interference between the two or friction are reduced to minimum.

In this case, be necessary to prevent that lever 120 and slide block 130 are separated from each other and the vertical mobile component of the rotation of lever 120 be transformed into the vertical mobile component of slide block 130 the biglyyest.

For this reason, preferably, lever 120 has the enhancing rib 120a that forms in the inboard of lever 120, and rib 120a have with at the consistent sweep 120b of the open lower side 131a at insertion groove 131 places.Preferably, the radius of curvature of sweep 120b is greater than the radius of curvature of opening 131a.

In the state that lever 120 does not rotate, sweep 120b has certain interval with respect to opening 131a.Yet, along with the rotation of lever 120, because slide block moves up, so sweep 120b contacts owing to radius difference forms linearity in theory with opening 131a.Therefore, when the two was in linear contact, friction was reduced to travelling forward of minimum and slide block and is restricted, and prevents that thus the two is separated from each other.That is, be separated from each other, realized that by the lever rotation maximum of slide block moves upward by preventing the two.

With reference to figure 6 and 7, shell 150 can have guiding piece 140.Guiding piece 140 guide shoe 130 move up and down.Therefore, preferably, guiding piece 140 is located at the opposite side of slide block 130.

Slide block 130 can have the guiding rib 130a consistent with guiding piece 140.Guiding piece 140 has hook shape, and guiding rib 130a is arranged in the hook of guiding piece 140, with a left side/right motion of restriction slide block 130.

Guiding piece 140 is set for fastening slide block 130 in shell 150.Therefore, fastening more reliably in order to realize, guiding piece 140 can be set for fastening four positions, that is, and and on the slide block/a following and left side/right side.

And guiding piece 140 restriction slide blocks 130 move up and down in preset range.Promptly, the moving upward of slide block 130 is restricted to when making the guiding piece 140 that forms at upside and the upper side wall of insertion groove 131 form contact, and moving downward of slide block 130 is restricted to when making when the guiding piece 140 of downside formation contacts with the lower wall formation of insertion groove 131.

Simultaneously, with reference to figure 5, supporting leg 111 is located at and is used to push and the rear wall of the button 110 of rotating lever 120.Supporting leg 111 can have the cam lever shape.Preferably, supporting leg 111 is located at the position of the downside that makes it possible to extrusion lever 120 front portions.Because far away more from lever shaft 121, it is more little to be used to push required active force.

With reference to figure 5 and Fig. 6, if push supporting leg 111, then lever 120 rotations are with the lower end of the lever 120 that moves up.Therefore, in the state that the lower end of lever is rotated, the motion of lever trends towards being subjected to the restriction of the lower end of lever 120.In order to prevent this from occurring, at the lower end formation receiver 122 of lever 120, to be used to receive supporting leg 111.Preferably, receiver 122 is formed towards supporting leg 111 outstanding, has semicircular in shape simultaneously.With it side by side, preferably, the radius of the inboard of receiver 122 is greater than the radius of supporting leg 111.In view of the above, though supporting leg be not flatly but from the horizontal by certain angle in the situation that moves, also can make supporting leg not move away the fixed range that receiver forms.Similarly, because when lever 120 rotations, make supporting leg 111 form and contact that the variation of supporting leg moving direction can be corrected with receiver 122.

If supporting leg 111 is not the positive center of extrusion lever bottom, but along leaving this RC part left or to right, then lever trends towards rotation when being distorted.If utilize the supporting leg 111 with little cross section to push the lever with big cross section, then this will be more significant.Therefore, in order to prevent this from occurring, shell 150 can have lever guide spare 141, is used to make the bottom of lever to move and the distortion of a left side/right does not take place.

With reference to figure 7, lever guide spare 141 can be a groove, and this groove preferably has the shape consistent with the shape of receiver 122.In view of the above, because move the bottom of receiver, so can prevent lever a left side/right distortion takes place in lever guide spare 141.Tend in order to distribute along a left side/active force of right distortion lever, preferably, the lever guide spare 141 that a plurality of receivers 122 is set and matches.Fig. 7 signal wherein is provided with a kind of example of three described receivers and lever guide spare.

To switch element 300 be described with reference to figure 2.

Switch element 300 is spaced apart with the opening operation unit of describing before 100.Most of door switch assembly 10 is arranged in shell 600, and shell 600 is spaced apart with opening operation unit 100.

Shell 600 as the body of door switch assembly 10 holds the various parts that comprise switch element 300, thereby protects it not to be subjected to external environment influence.

Because switch element 300 in order to breech lock 51 door relatively, so be adjacent to patchhole 610 switch elements 300 (see figure 1)s are installed.That is, preferably, be adjacent to patchhole 610 switch element 300 is installed in shell 600.

Switch element 300 receives active force that is applied by opening operation unit 100 by the user or the change in location that is caused by this active force.Such as previously described, because opening operation unit 100 and switch element 300 are spaced apart certain distance, thus transmission member is set, to be used for transfer function power or change in location between the two.Fig. 2 illustrates cable 200 as an example.

Switch element 300 can comprise cable lever 310, is used for receiving the linear direction change in location by cable 200.

Particularly, the cable lever 310 that is connected to cable 200 receives users are applied to the opening operation unit by cable 200 active force.In this case, cable lever 310 can be designed to be transformed into the position of rotation variation by the active force that cable 200 receives.By fixing an end in rotatable mode and the other end being connected to cable 200, cable lever 310 can rotate along with the vertical motion of cable 200.

In this case, be fixed to torsionspring 311 by the end with cable lever 310, if the user pushes opening operation unit 100 to realize the upwards change in location of cable 200, then cable lever 310 can rotate up.Yet, after the user removes pushing on opening operation unit 100, utilizing the restoring force of torsionspring 311, cable 200 can turn back to initial position.

In this case, cable 200 moves up vertically, and correspondingly, when 310 rotations of cable lever, the other end of cable lever 310 moves up.Therefore, if cable 200 moves up, to produce load along its radial direction on cable lever 310, then cable 200 might separate with cable lever 310.If cable 200 loosely is connected to cable lever 310, then might the user operation of opening operation unit 100 directly be delivered to cable lever 310.Similarly, operate the situation that moves up before the opening operation unit 100 at cable the user, user's operation is nonsensical.

Therefore, need a kind of structure, be used to keep reliably fastening between cable 200 and the cable lever 410, and the length of cable between opening operation unit 100 and switch element 300 is in the correct scope.

To be described in detail in a kind of syndeton between opening operation unit 100 and the switch element 300 with reference to figure 8 and Fig. 9.

Such as previously described, the other end of cable lever 310 can be the cable receiver 312 that receives the end of cable 200.Connecting elements 230 is located at the place, end of having of cable 200 cross section bigger than the other parts of cable.Therefore, owing to insert the connecting elements 230 with cross section bigger than the other parts of cable in cable receiver 312, thereby fastening between the two becomes more reliable.

Preferably, connecting elements 230 has the bent side of the friction that is used for minimizing cable receiver 312.With it side by side, preferably, the length of connecting elements is greater than its width.Connecting elements 230 with cylindrical shape is shown.

With reference to figure 8, cable receiver 312 has open front and open top.By its front portion, connecting elements 230 and cable 200 can be placed in the receiver 312, and by this open top, cable can extend upward.

In further detail, in the front portion of cable receiver 312, form under shed 312b and last side opening 312c with configurations differing from one.Under shed 312b can be formed has the rectangular shape consistent with the longitudinal cross-section of connecting elements, to place connecting elements 230 therein.In this case, preferably, under shed 312b has the width greater than the width of connecting elements.Yet preferably, under shed 312b has the height of the height that is lower than connecting elements.This is in order to place connecting elements 230 by under shed 312b when connecting elements 230 tilts.Therewith, under shed 312b has step part 312e in its initial import department, so that the inner space 312f of cable receiver 312 is bigger.In view of the above, as shown in FIG. 8, in receiver 312, the connecting elements of placing therein when connecting elements tilts can be erect.This structure makes the gravity of the cable lever cable of can leaving behind at least, and at the upside of inner space 312f, connecting elements 230 can always be erect.In view of the above, connecting elements 230 is not escaped by under shed 312b.Even if connecting elements 230 is positioned at the downside of inner space 312f, connecting elements 230 is not escaped by under shed 312b yet, and this is because according to the position of cable, be difficult to tilt connecting elements 230.

Simultaneously, preferably, side opening 312c has and wherein goes up the structure that side opening 312c then becomes big more at opening more upwards the time in the front portion of cable receiver, and the open top 312a in the top side of cable receiver has the structure that open top 312a wherein becomes more little when opening is downward more.That is, preferably, open top 312a has the structure that is similar to funnel, contacts to be used to preventing to make cable 200 to form with cable receiver 312, thereby causes cable to damage.With it side by side, preferably, form base portion 312d, the upside of connecting elements 230 is placed and be fixed in this being used at the upside of inner space 312f.This is in order to settle connecting elements 230 when cable 200 extends upward, move to prevent connecting elements 230, thereby change in location is delivered to switch element 300 from cable as much as possible on base portion 312c.

With reference to figure 9, can cable 200 be connected to cable lever 300 from the outside of the shell 600 of door switch assembly 10.

In further detail, shell 600 can have patchhole 671 in a side, be used for making connecting elements 230 can be placed on this shell.With it side by side, a described side of this shell can have the groove 670 of the bearing of trend formation that is parallel to cable.Can be by making the inboard recessed groove 670 that forms of shell.And, groove be configured to limit cable left with to the motion of right.Therefore, be desirable to, groove be set along the longitudinal direction of cable.

In this case, can be from the outside of shell 600 cable 200 be connected to switch element 300/ shell from its disconnection.In view of the above, if cable 200 is out of order or need the change installation site, then can only remove cable 200 so that length is regulated.That is, be very easy from its disconnection, so cable 200 is connected to switch element 300/ because need not to disassemble shell 600.

Simultaneously, the outside of cable 200 can be located in cover part 210.Because, be adjacent to accommodating laundry cylinder etc. cable 200 might by water or because other be former thereby damage.

The opposed end of cover part 210 is fixedly secured to shell 150 (see figure 5)s and the shell 600 of opening operation unit 100 respectively, and cable 200 further extends and is connected to slide block 130 (see figure 5)s of opening operation unit 100 and the cable lever 310 in the shell 600.

In this case, the opposed end of cover part 210 or an end can have the retainer 220 that is coupled to shell 600 or shell 150.Retainer 220 can be placed in the retainer receiver 660 in shell 600 or the opening operation cell enclosure 150.

According to the character of cable 200, if tension buildup ground takes place, then cable 200 is easy to produce plastic deformation, thereby extends longlyer than initial length.When the length of cable 200 was longer, this distortion became bigger.In view of the above, change in location from opening operation unit 100 to switch element 300 correct transmission may fail.Therefore, need minimize the length tolerance limit of accumulation cable distortion.

Such as previously described, opening operation unit 100 and switch element 300 are spaced from each other, and in most cable part, cable is provided with cover part 210, retainer 220.The cover part has the retainer 220 that is positioned at the opposed end place, and this retainer is fixed to retainer receiver 660.In view of the above, the plastic deformation of cable is minimized.Therefore, can make about accumulating the tolerance limit minimum of cable distortion.

The casing 20 of washing machine has wet environment.Wet steam is by hot water or hot-air condenses and infiltrate in the shells 600 along cable 200 especially cover part 210.Electric component and metal parts such as spring can be arranged in shell 600.Therefore, water droplet need be discharged into the outside of shell 600 from shell 600.

For this reason, draining rib 640 (see figure 2)s can be located at the lower end of cable 200, especially, are located at the downside of cable receiver 312, are discharged into the outside of shell 600 with the water droplet that is used for being penetrated into this along cable 200.Draining rib 640 can be downward-sloping.In view of the above, water droplet can be discharged to the outside of shell 600 via draining rib 640 by patchhole 671.

Therefore, the patchhole 671 in shell 600 makes it possible to from the outside of shell cable 200 is connected to cable lever 310, and will be discharged to the outside of shell along the water droplet that cable is penetrated into this.

To describe other member of switch element 300 with reference to figure 2 in detail.

Switch element 300 can comprise be connected to cable lever 310 wave slide block 320.Preferably, waving slide block 320 can move up and down along with the rotation of cable lever 310.

Cable lever 310 can have protruding 310a (see figure 9), and waves slide block 320 and can have the hole 320a that is used for inserting therein protruding 310a.In view of the above, along with the rotation up and down of the part of cable lever 310, wave slide block and move up and down.This is similar to the crankshaft structure of automobile.Yet preferably, hole 320a has the shape of slotted hole, and this shape has the above-below direction width bigger than a left side/right width.As describing ground afterwards, this is because when cable lever 310 moves up, need to postpone to wave the translation of slide block 320.In this case, waving slide block 320 when static, protruding 310a moves, thereby upwards slides one section limited distance in the 320a of hole.

Switch element 300 can comprise the cantilever of cam lever 300.Cam lever 300 is so arranged, and make the one end be fixed to the inboard of shell 600, and its other end can go up/descend or forward/backward moves.

In further detail, an end of cam lever 330 can be fixed to the inboard of shell 600 by elastic component 331.Elastic component 331 can be a wind spring.That is, preferably, elastic component 331 has the recovery characteristics with respect to the compression and the elongation of preset distance, together with the recovery characteristics with respect to the predetermined angular rotation.

Yet, if elastic component 331 is long, then that elastic component 331 is trended towards is sagging owing to the load of the gravity of elastic component 331 or cam lever 330, and needs to set in preset range respectively compression and the elongated distance and the anglec of rotation of strain.For this reason, elastic component 331 part can be inserted in the cam lever and be fixed to cam lever.For fastening this elastic component, can use pin 332.

Preferably, cam lever 330 is connected to and waves slide block 320 320 to move with waving slide block.For this reason, cam lever can have formation protruding (not shown) thereon at a side place, and waves the hole (not shown) that slide block 320 can have and projection as one man forms therein.That is, at cam lever 300 and wave that connection between the slide block 320 describes before can being similar at cable lever 310 and wave connection between the slide block 320.In view of the above, move up if wave slide block 320, then cam lever 330 also rotates up, and if wave slide block 320 and turn back to initial position, then cam lever 330 also is rotated down.

At last, the rotation of cable lever 310 is waved slide block 320 and is delivered to cam lever 330, thereby makes cam lever 330 and cable lever 310 move similarly.

Switch element 300 can comprise rotating cam 340.Can be adjacent to patchhole 610 so that rotating cam 340 rotatably to be installed.Rotating cam 340 can be designed to 300 move with cam lever.

With reference to figure 2, preferably, rotating cam 340 has rotating shaft 341 at the rear portion of patchhole 610, and rotating shaft 341 is located on the side of the breech lock that inserts in the parallel with it patchhole 610.In view of the above, the breech lock 51 that is so inserted can be vertical mutually basically with rotating shaft 341.This is in order to make when breech lock is positioned at patchhole 610 inside/outsides rotating cam 340 rotations.In other words, this is to rotate breech lock 51 is placed patchhole 610 inside/outsides for rotating cam 340.

Preferably, rotating shaft 341 is provided with torsionspring 342.In view of the above, if utilize external force to rotate this rotating cam 340, then can produce restoring force, so that rotating cam 340 turns back to initial position.

Simultaneously, preferably, rotating cam 340 has cam body 343.Cam body 343 can be formed when cam body 343 rotates around rotating shaft 341 has radius variable in specific location.For example, as shown in Fig. 2 and Fig. 4, cam body 343 can be formed have fan-shaped.With it side by side, preferably, rotating shaft 341 is located at the eccentric position place of cam body 343.

In view of the above, along with the rotation of rotating shaft 341, cam body 343 can only keep in touch or push away cam lever 330 with cam lever 330.Simultaneously, cam body 343 can have hook 344 and is connected to form with breech lock 51 with 345 at a side place.The position of rotation that hook 344 and 345 is formed according to rotating cam 340 is exposed to patchhole 610, thereby when the breech lock 51 of door 50 is inserted in the patchhole 610,

hook

344 and 345 rotation rotating cams 340.

Preferably, rotating cam 340 has first hook 344 and second hook 345.Generally, cam body 342 and

hook

344 and 345 can have fork-shaped.In this case, when inserting the breech lock 51 of door, when first hook 344 was promoted by the front end of breech lock 51, first hook 344 can be used to rotate rotating cam 340.Second hook 345 that 344 rotates with first hook can be inserted in the latch hole 52 (seeing Figure 12) to engage with

breech lock

51 and 51 to rotate with breech lock.

Therefore, if fully insert breech lock 51 inserting in the hole, then when second hook 345 engages and is fixed to breech lock 51, first hook 344 that is promoted backward by the front end of breech lock 51 trends towards clashing into the rear wall of shell 600.Thereby cause therefore at first hook 344 bump shells 600 can to have problems in the situation of wearing and tearing that wherein when breech lock 51 was inserted in the door 50, first hook 344 can not engage with the front end of breech lock 51, thereby can not rotate rotating cam 340.Therefore, in this embodiment, even if first hook 344 can not interfered shell 600 yet when making first hook 344 rotate to maximum, shell 600 can have through hole 650 in rear wall, thereby guarantees the rotate path of first hook 344.

With reference to figure 2, door switch assembly 10 makes its most of parts be arranged in shell 600.Some parts move or rotate along the outer casing thickness direction around rotating shaft along the width of shell in shell 600.In view of the above, shell 600 can approach, so that can form shell very compactly.Yet, along with the rotating cam 340 of the motion of breech lock rotation and hook 344 and the 345 thickness direction forward/backward along shell move.Therefore, in order to guarantee this motion fully, it is thicker that shell 600 trends towards becoming.Therefore, by in shell 600, forming through hole 650, can prevent that shell from becoming thicker on the whole.

Fig. 2 is shown in the breech lock 51 of the door 50 that inserts in the patchhole 610.

Such as previously described, when in patchhole 610, inserting breech lock 51, first hook 344 of rotating cam 340 is promoted backward by the front end of breech lock 51, and second hook 345 that engages with latch hole 52 in rotating cam 340 is along clockwise direction rotation rotating cam 340.Yet, preferably,, when door 50 is closed, utilize the other end of cam lever 330 to make that a side of cam body 343 is static, with the position of rotation of restriction when cam body 343 rotates if in patchhole 610, insert breech lock 51.That is, keep the closed condition of door 50.

For this reason, such as previously described, preferably, cam body 343 has fan-shaped.If cam body 343 is formed in the circle in deciding on the rotating shaft 341, keep fixed range between cam lever 330 and the cam body 343 with all position of rotation places at rotating cam 340, then can not be only the restriction that realizes the position of rotation of cam body 343 of the cam lever 330 of a side by supporting cam wheel body 343.As shown in FIG. 2, have fan-shaped cam body 343, and make and a side of cam lever 330 supporting cam wheel bodies 343 can realize restriction the position of rotation of cam body 343 by providing.

In view of the above, although there is the restoring force be used to turn back to initial position, the position of rotation of rotating cam 340 also is restricted, and in breech lock 51 and state that second hook 345 engages, and 50 can be secured to door switch assembly 10.

Yet the shape of cam body 343 of the present invention is not limited to fan-shaped, but is changed according to the position of rotation of cam lever 330, as long as the position of rotation of cam lever 330 is restricted.For example, cam body 343 can also have ellipse or on rotating shaft the shape of the circle in eccentric fixed, perhaps be used for changing the rank shape part of radius according to position of rotation.

To describe the operation mechanism along with the opening/closing of door 50 of door switch assembly 10 with reference to figs. 2 to Fig. 4 in detail.

Fig. 2 illustrate the door 50 pent states.Therefore, if there is not the Any user operation at 100 places, opening operation unit, then opening operation unit 100 is in the original state, and door is in the closed condition, wherein breech lock 51 is inserted in the patchhole 610, and rotating cam 340 is in the rotation status and cam lever 340 is in the state of restriction rotating cam 340.Because the restoring force of the cam lever that produces when cam lever is compressed along with the recovery of rotating cam 340 is greater than the restoring force of rotating cam 340.

Fig. 3 illustrates the user to operate opening operation unit 100 to open the state of door 50.

If the user applies active force by opening operation unit 100, then cable 200 is upwards spurred, to move the switch element 300 that is connected to cable 200.

At first, the cable lever 310 that is connected to cable 200 moves up.Then, along with moving upward of cable lever 310, the slide block 320 that waves that is connected to cable lever 310 moves up.Being connected to the cam lever 330 that waves slide block 320 also rotates up.

When cam lever 330 rotated up, rotating cam 340 was disengaged by the state that cam lever 330 limits.In view of the above, by using the restoring force of torsionspring 342, rotating cam 340 can turn back to initial position, that is, and and the position before inserting door 50.In this case, along with the rotation of rotating cam 340, the breech lock that engages with second hook 345 51 of door 50 is outwards promoted by the direction along cam lever 330, and door 50 can be opened.

Simultaneously, rotating cam 340 promotes breech lock 51 and opens door with the elastic force of utilizing elastic component.This elastic component can be a torsionspring 342.Therefore, door can automatically be opened.And elastic component for example torsionspring (not shown) can be located at hinge 53 and sentence direction is opened in generation along door elastic force.In view of the above, thus can save the outward appearance that door handle improves washing machine.

Fig. 4 illustrates door 50 to be opened and is applied to the state that the active force of opening operation unit is disengaged.

That is, if the active force that pulls cable 200 by opening operation unit 100 is removed, then pass through the restoring force of first torsionspring 311 of cable lever 310, cable lever 310 is rotated down, and cable 200 down changes the position.

In view of the above, wave slide block 320 and move down, and cam lever 330 also is rotated down, so that rotating cam 340 is turned back to original state.Because elastic force is removed by the elastic component 331 from cam lever 330, the total length of cam lever 330 becomes the longest.Therefore, the other end of cam lever 330 turns back to the initial position of the upside of cam body 343.Also as shown in FIG. 4, thus this state is a cam lever 330 is bent upwards the state that trends towards utilizing the restoring force of gravity and elastic component 331 and move down.

Simultaneously, when door 50 is closed once more, rotating cam 340 rotations, and in the moment that door is fully closed, cam lever 330 can turn back to original state.Preferably, this is formed with taking in cam body 343.

In this case, cam lever 330 is moved down into rotating cam 340 1 sides from the upside of rotating cam 340, and has the ticktock sound from elastic-restoring force.According to sound perception, the user can know clearly that door 50 has been closed.In Fig. 2, illustrate state after this, that is, and the state that door is fully closed.

Such as previously described, from the elastic force of cam member restoring force greater than rotating cam 340.Therefore, short of any other active force is applied to door, and door just is not opened.

Yet, when children are in cylinder, in the pent situation of door, being desirable to, children can open door.That is, be desirable to, utilize children can promote door 50 active force and can open door 50 from cylinder inside.For this reason, can select the elastic modelling quantity of the elastic component 331 of cam lever 330.

Elastic modelling quantity is high more, and it is big more then to open the required active force of door, and elastic modelling quantity is low more, and it is more little then to open the required active force of door.Yet if elastic modelling quantity is low excessively, the ticktock sound of describing will become very little before, thereby make whether be very difficult to decision gate is closed.Consider these all situations, can suitably select elastic modelling quantity.

Except the above system of door switch assembly 10, door switch assembly 10 can comprise the lock cell 400 of the lock-out state that is used to keep door 50.Lock cell 400 can be provided by the mechanical movement of limit switch unit 300.

Preferably, lock cell 400 can be designed to can not open door 50 during washing operation.That is, preferably, during washing operation, the user can not be by gripping door and even utilizing the opening operation unit of describing before 100 to open door.

Certainly, during washing operation, electric power is applied to washing machine.Therefore, preferably, only during washing operation, electric power is applied to lock cell 400.In view of the above, lock cell 400 can be designed to only can be operated during washing operation.Thus, can consider the driving condition of washing machine and optionally keep door 50 lock-out state.

In the situation that has a power failure, be cut off because be used for the electric power of washing machine self, thereby, can open door 50 by pushing opening operation unit 100 owing to there is not electric power to be supplied to lock cell 400 and the state that automatically unlocks.In view of the above, can avoid because washing machine for a long time clothing being kept somewhere in washing machine of breaking down etc. and to cause.

To describe the operating principle of lock cell 400 with reference to figure 2 in detail.As a reference, Fig. 2 illustrates the state that lock cell 400 separates with switch element 300.

Lock slider 320 can comprise the retaining part 321 that is adjacent to lock cell 400.Retaining part 321 can be formed the shape that the downside that waves slide block 320 is bent.Stop pin 410 (see figure 10)s can be installed to towards the position of the retaining part 321 that waves slide block 320.In this case, stop pin 410 can be designed to outstanding and return to/dash area from Fig. 2 322.

Such as previously described, in order to open door, the cam lever 330 that need be moved upward moves up.For the cam lever 330 that moves up, need wave slide block 320 and move up.Therefore, be restricted, then can keep locked door condition if wave moving up of slide block 320.

Simultaneously, wave slide block 320 and be connected to cable lever 310.Therefore, be restricted if wave moving up of slide block 320, then moving up of cable lever 310 also will be restricted.Yet, can utilize the operation of opening operation unit 100 and realize moving up of cable lever 310, need to allow cable lever 310 segment distance that moves up.Because if cable lever 310 does not move in locked door condition, then cable 200 and opening operation unit 100 can not move.In view of the above, might very strong active force can be applied to opening operation unit 100 applying strong tension force to whole system, thereby damage door switch assembly 10.And, do not move if opening operation unit 100 is basic, then the user can determine opening operation unit 100 and breaks down owing to misunderstanding.

Therefore, in the lock-out state of door 50, need to allow opening operation unit 100 to operate, and in limited range, make progress mobile cable 200 and cable lever 310.Certainly, in this case, wave slide block 320 and cam lever 330 and do not move.

For this reason, such as previously described, lock slider 320 has the slotted hole 320a that forms therein, and the protruding 310a of cable lever 311 connects in slotted hole 320a slidably.

In this case,, wherein wave the path that slide block 320 can move up along with the motion of stop pin 410, motion that can limit switch unit 300 by being limited in according to applying electric power to lock cell 400.

That is, even if the user pushes opening operation unit 100, owing to wave locked pin 410 restrictions of the motion of slide block 320, so door 50 is not opened yet.In view of the above, can avoid causing accident owing to ignoring security.

To lock cell 400 be described with reference to Figure 10.

The stop pin 410 that can move under electric power control is installed in the lock cell 400.If apply electric power, then stop pin 410 can pass the hole (not shown) in the fore shell (not shown) of lock cell 400 and outstandingly wave moving up of slide block 320 with restriction.In this case, stop pin 410 is projected into the retaining part 321 that waves slide block 320 and waves moving up of slide block 320 with restriction.If electric power is cut off, then stop pin 410 returns allowing to open door 50, thereby makes that waving slide block 320 can move.That is, when stop pin 410 moves perpendicular to the moving direction that waves slide block 320, can limit and wave moving up of slide block 320.

A prerequisite is that the electric power that is applied to lock cell 400 is the main electric power that is applied to washing machine.Therefore, when main electric power is cut off or when having a power failure, certainly, be cut off to the electric power of lock cell 400.Yet,, also exist the user when finishing washing operation or suspending washing operation, need open the situation of door even if apply main electric power.In this case, the controller (not shown) of washing machine is designed to optionally apply electric power to lock cell 400.

Lock cell 400 can comprise the position regulating unit that can additionally control the forward/backward motion of stop pin 410.This position regulating unit can comprise bimetallic or the solenoid that is used for the position of control stop pin 410 under electric power control.

For example, provide bimetallic lifter 420 can be set to position regulating unit.Bimetallic uses has two kinds of metals of different heat expansion coefficient, thus have wherein bimetallic when temperature raises along certain orientation feature crooked and recovery original shape when temperature is returned.

With reference to Figure 10, lifter 420 can be connected at this and apply terminal 421 electric power, that be adjacent to stop pin 410.In view of the above, be applied in the situation of lock cell 400, thereby cause that lifter 420 temperature raise to front curve, and do not have electric power to be applied in this, cause that lifter 40 temperature descend, to recover original shape at electric power.In this case, as the device that is used to heat, can use ptc heater.Be applied in this moment at electric power, ptc heater generates heat to cause the bimetallic bending.If electric power is cut off, then ptc heater is cooled to cause that bimetallic returns initial position.In view of the above, stop pin 410 can and return as one man and give prominence to/return with the bending of lifter 420.

Yet because bimetallic feature, if electric power is cut off during applying electric power, the temperature of lifter 420 descends lentamente, thereby requires a period of time so that the stop pin that is so moved up turns back to initial position.Therefore, there is following problem, that is,, can not be opened at a period of time inside door 50 even after finishing driving.

In view of the above, lock cell 400 can comprise the latch-release unit 430 of the compulsory commutation of the lock-out state that is used to realize door 50.That is the system that can additionally provide a kind of pressure that is used to realize stop pin 410 to return.Be different from switch element 300 etc., latch-release unit 430 can be arranged in the shell 440 with lifter 420.

Latch-release unit 430 makes and by controller electric power is optionally put on this.Therefore, after just finishing washing operation, in the predetermined situations suspended or the like of washing operation, controller applies the compulsory commutation of electric power to be used to realize lock to latch-release unit 430.In view of the above, the user can open door and need not wait for that lifter turns back to initial position.

Latch-release unit 430 can comprise along with applying electric power and mobile solenoid 423 and conductor 424 to solenoid 423.In view of the above, stop pin 410 can be designed to move with this conductor.

That is, if electric power is applied to solenoid 423 realizing compulsory commutation, thereby then this conductor moves in the pressure mode and makes stop pin 410 move.After this, if be cut to solenoidal electric power, then can utilize elastic component etc. to make this conductor return.In this case, because the temperature of lifter 420 descends fully, so no matter whether conductor returns, stop pin 410 also can be kept return state.

Simultaneously, with reference to Figure 10, can between conductor 424 and stop pin 410, various parts be set.

Can so design, that is, conductor 423 moves down if electric power is applied to solenoid 423, and then wire 432 is pulled, and spool 425 can additionally be provided, thus along with the pulling of wire 423 spinning reel 425.In this case, can be designed to utilize being rotated counterclockwise of spool and return stop pin 410.

Simultaneously, be cut to the electric power of solenoid 423, conductor 423 can turn back to initial position.For this reason, elastic component 432 can be located between conductor 423 and the spool 425.In this case, because the wire 423 lax clockwise directions that produce rotate, stop pin 410 trends towards moving down by spool 432.In order to prevent this situation, cam 425 can have along the acclivitous tooth (not shown) of direction of rotation, so that return when cam 425 stop pin 410 when counterclockwise rotating, and make and do not rotate when cam 425 stop pin 410 when clockwise direction rotates.

Therefore,, then be used to the signal of self-controller, can unlock state immediately and need not wait for when the temperature of lifter 420 descends if this design is provided.

In this case, this lock cell can be provided with and be designed to make that electric current flow to this contact (not shown) in open mode.This contact can be designed to open in the position of the motion of stop pin 410 limit switch unit 300, promptly opens at the restriction site place.Therefore, this contact, perhaps is closed in the moment that stop pin 410 turns back to restriction site to restriction site between moving period at stop pin 410.Be opened then apply the electric power that is used to make it possible to carry out washing operation if controller can be designed to the contact, and if the contact be closed then cut off electric power to stop washing operation.

Simultaneously, the door 50 of washing machine can take place because external impact etc. and by the unexpected situation of opening.Preferably, when door 50 was so unexpectedly opened, washing operation stopped, to prevent when cylinder can rotate owing to ignoring the accident generation that security causes.

Therefore, door switch assembly 300 can comprise the opening/closing detecting unit 500 of the opening/closing that is used for sensing door 50.Preferably, 50 accidents are opened if opening/closing detecting unit 500 senses door, and then controller is controlled to finish washing operation.Controller stops washing operation when in this case, can be closed in definite contact.

To opening/closing detecting unit 500 be described with reference to figure 2 and Figure 10.

Opening/closing detecting unit 500 can be so that an end be located at patchhole 610.Particularly, a described end of opening/closing detecting unit 500 is formed and is exposed to patchhole 610, and its other end can be connected to the elastic component 510 that is fixed to shell 600 inboards.

If door 50 is not closed, then a described end of opening/closing detecting unit 500 is positioned at a side of patchhole 610.Yet, if door 50 is closed so that breech lock 51 is placed in the patchhole 610, thus opening/closing detecting unit 500 pushed along the direction vertical by breech lock 51 and slide with the direction of inserting breech lock 51 along it, that is, slide into the inside of shell 600.Therefore, according to the slip of opening/closing detecting unit 500, can sense the opening/closing of door 50.

In this case, preferably, form the sliding path of opening/closing detecting unit 500 by the member such as rib of use in shell 600.More preferably, thereby a described end that is exposed to patchhole 610 directions has the cross section that contacts with the breech lock 51 that tilts along glide direction in door 50 pent situations, and a described end is towards slides within, and this end is promoted backward by breech lock 51 simultaneously.

If opening/closing detecting unit 500 senses door 50 and opened by accident, then preferably, thereby washing machine is controlled in the pressure mode and stops washing operation.

Thereby opening/closing detecting unit 500 can be electrically connected to controller and directly provide the forced termination signal to controller.Opening/closing detecting unit 500 can be electrically connected to controller 500 by using lock cell 400.

Opening/closing detecting unit 500 can additionally comprise the latch-release rib 520 that extends along the direction vertical with glide direction.According to the opening/closing of door 50, latch-release rib 520 slides with opening/closing detecting unit 500.

In this case, preferably, in door 50 pent states, when the position and lock of turning up the soil at interval from the outstanding herein point 520 of stop pin 410 is removed rib 520, if door 50 is opened by accident, then stop pin 410 slides towards the outstanding herein point 50 of stop pin 410.It for example is that door is opened during washing operation that the accident of door 50 is opened.That is, because during washing operation, keep the lock-out state of door 50, so stop pin 410 is in the outstanding state.

The cross section of Figure 11 signal line A-A ' intercepting in Fig. 2.Yet though Fig. 2 illustrates the state that lock cell 400 is separated, Fig. 6 illustrates a cross section, thereby this cross section illustrates lock cell 400 coupled states position relation with stop pin 410 is shown.

Fig. 2 signal 50 pent states of going out, wherein as shown in FIG. 6 outstanding like that of the stop pin 410 of lock cell 400 in washing operation.

When door 50 is closed, opening/closing detecting unit 500 is towards the slides within of shell 600, latch-release rib 520 is fixed in the state of opening with the location interval of stop pin 410, and waves slide block 320 and be in and wave moving up and down of slide block 320 and be subjected in the state of stop pin 410 restrictions.

If door 50 is unexpectedly opened, then when opening/closing detecting unit 500 when patchhole slides, latch-release rib 520 also slides with pressing lock rationed marketing 410, thereby makes stop pin 410 turn back to the inside of lock cell 400.That is, if door 50 unexpectedly opened, thereby make position regulating unit can not move down stop pin 410, then the latch-release rib 520 of opening/closing detecting unit 500 can be with the unlock lock-out state of unit 400 of pressure mode.

Preferably, latch-release rib 520 has from the downside oblique inclined surface of inclination that makes progress, thereby makes and be easy to return when pressing lock rationed marketing 410.In this case, from the top of stop pin 410, pressing operation carries out lentamente, thereby makes it possible to return stop pin 410 and do not have interference.

Therefore, in the situation that door 50 is unexpectedly opened, opening/closing detecting unit 500 can transmit a fact to lock cell 400, and promptly the compulsory commutation of the lock-out state by stop pin 410 makes 50 to open.

Be electrically connected to controller with the lock cell 400 that is used for transmitting/receiving signal when unlocking state in the pressure mode, stop to drive washing machine thereby can drive stop signal to the controller transmission.Promptly, thereby controller applies electric power to lock cell 400 and keeps locked door condition with outstanding stop pin 410 when washing operation, in contrast, the electric power that is cut to lock cell 400 when washing operation finishes to be returning stop pin 410, thereby removes locked door condition.Therefore, because controller controls to carry out washing operation under the outstanding hypothesis of stop pin 410, if stop pin 410 is returned in the pressure mode, thereby then controller can be controlled in the pressure mode and stops washing operation.

With differently above, lock cell 400 can have the cutting unit (not shown) of the driver element power supply that is used to be cut to washing machine.In this case, can so design, make when opening/closing detecting unit 500 unlocks state in the pressure mode, be cut to the power supply of driver element by using cutting unit.Can be mechanically provide cutting unit with the shape of switch, this switch moves with opening/closing detecting unit 500.

Therefore, thus can be provided with state that the contact controller detects the contact with optionally to the driver element power supply, perhaps directly apply or be cut to the electric power of driver element by the close contact.

Yet this is exemplary, and feasible certainly is that opening/closing detecting unit 500 is to be adjacent to an a kind of sensor (not shown) that waits installation, and opening/closing detecting unit 500 is directly to the unexpected signal of opening of controller transmission gate 50 quilts.

To the operative relationship of lock cell and opening/closing detecting unit for the opening/closing of door be described.

At first, if door is closed, then the opening/closing detecting unit is towards the slides within of shell.

If washing operation begins, then along with applying electric power to lock cell 400, the outstanding mobile route that waves slide block with restriction of stop pin.In view of the above, during washer operation, utilize stop pin to keep lock-out state, in this state, switch element is not removable.That is, PTC generates heat with crooked bimetallic, thereby mobile stop pin 410 is to keep lock-out state.

If washing operation finishes or suspends, the electric power that then is cut to lock cell 400 is to turn back to initial position with stop pin 410.In view of the above, lock-out state is disengaged.Yet for the state that unlocks immediately, whether the electric power that controller is determined to PTC is cut off.If the electric power to PTC is cut off, thereby then controller is controlled stop pin 410 and is turned back to initial position in the pressure mode.Certainly, with it side by side, will need controller to determine whether washing operation carries out.That is, if washing operation is stopped or finishes, and be cut off to the electric power of PTC, then controller makes solenoid begin operation, has nothing to do and turned back to initial position with stop pin 410 by bimetallic.

Therefore, because lock-out state is disengaged, so the user can operate opening operation unit 100, to open door 50.In the situation that door is opened, opening/closing detecting unit 500 utilizes the restoring force of elastic component 510 to slide towards the direction of patchhole 610.Yet because this is the state that stop pin 410 has returned, latch-release rib 520 does not push stop pin.

Simultaneously, if door is unexpectedly opened during operation, then stop pin 410 can not return, and this is because lock cell 400 is in the state that electric power is applied in this.Therefore, make opening/closing detecting unit 500 when the direction of patchhole is slided when opening, thereby latch-release rib 520 extruding stop pins 410 return in the pressure mode owing to door is unexpected.Then, possible is, opening/closing detecting unit 500 perhaps directly is cut to the electric power of the driver element of washing machine when return the signal that is used to stop washing operation when cutting off electric power to the controller transmission owing to the pressure of stop pin by cutting unit.

Simultaneously, if door 50 because the mechanically actuated of door switch assembly 10 and automatically being opened, then preferably, thereby reduces to rub friction when being minimized in door 50.

The details of the patchhole 610 and the breech lock 51 that are designed to minimize friction will be described with reference to Figure 12 and Figure 13.

Frictional force between patchhole 610 and breech lock 51 prevent the door open.Door is provided in the time of as mentioned above, can providing elastic component to be disengaged with the lock-out state when door.Therefore, it is very important reducing friction.

Preferably, at the part place that is adjacent to patchhole 610, shell 600 is formed the contact area that minimizes with breech lock 51.

Such as previously described, preferably, at the side formation patchhole 610 of shell 600, and the periphery of patchhole 610 has outward-dipping inclined surface 620.In view of the above, patchhole 610 can have following shape, wherein when patchhole 610 from the outside all the more when inboard, patchhole 610 becomes more little.

With reference to Figure 12, the downside inclined surface 620c of patchhole 610 can outwards tilt downwards, and the upside inclined surface 620b of patchhole 610 can up tilt.In this case, be that convenient breech lock 51 makes when being inserted in the patchhole 610 breech lock 51 form with inclined surface 620 to contact, because this contact is not the wherein surperficial surface contact that contacts with the apparent surface, and only be that its center line contacts with the line of relative line contact, so can minimize the friction of the motion of interfering breech lock 51.

More preferably, breech lock 51 can have shape like this, and wherein breech lock 51 becomes thinner the closer to its thickness of edge direction.In this case, can also reduce when breech lock 51 is inserted in the patchhole 610 and the line contact length of inclined surface 620.

Simultaneously, preferably, be side door 50 because gravity sag thereby the outside gradient of downside inclined surface 620c is formed inboard gradient greater than downside inclined surface 620c, breech lock 51 also can be inserted in the patchhole 610.

Usually, a kind of member is installed has a part that connects breech lock 51 herein such as the door 50 at the hinge at one side place, if door 50 is used for a long time, then because the gravity of door 50, this part trends towards sagging.Therefore, if door is seriously sagging, then breech lock 51 trends towards interfering the bottom of patchhole 610, thereby prevents that door from 50 correctly closing.Therefore, in order to compensate the sagging of predetermined extent, downside inclined surface 620c can be formed outward-dipping.

In this case, outside gradient is big more, and it is sagging then can to compensate serious more door 50.Yet,,, thereby make aesthetic property poor more so the size of patchhole is big more because the outside gradient of downside inclined surface is high more.

Therefore, preferably, downside inclined surface 620a has big gradient on the outside, and has little gradient on the inboard.In this case, be that side door 50 is sagging, breech lock 51 also can be inserted into the inside of patchhole 610 along the big inclined surface that forms on downside, and when breech lock 51 during towards progresses inside, can utilize second hook 345 along the support with favored policy surface and is directed into position latching.

In this case, downside inclined surface 620c can have gradient two different inclined surfaces mutually, perhaps has when the outside more then crooked big more inclined surface of inclined surface.

Simultaneously, Figure 13 is shown in the inclined surface of the opposite side formation of patchhole 610.

Along with the rotation of door 50, breech lock 51 rotates along radial path.Therefore, if additionally there is not any inclined surface in the periphery of patchhole, then might work as breech lock when being inserted in the patchhole 610, breech lock can be interfered shell 600.Particularly, because breech lock 51 when moving opposing

inclined surface

620c and 620d, compare the position that is positioned at door 50 fronts at a predetermined angle with door 50 and draw radius along lateral direction, breech lock 51 can be interfered the inclined surface 620c that forms on the outside of the radius of turn of door 50.

Therefore, preferably, relative tilt surface 620c has different gradient mutually with 620d, and more preferably, the inclined surface 620c on the radius of turn outside of door 50 has bigger gradient.In view of the above, if door 50 is being closed, then breech lock 51 can enter in the patchhole 610 and not interfere inclined surface 620c.

Can be described this as follows.That is, patchhole 610 is about the center asymmetry of the breech lock 51 that inserts in patchhole 610.That is, the width of patchhole 610 on the door radius of turn outside is formed greater than the width of patchhole 610 on door radius of turn inboard.Thus, the gradient of the outside inclined surface 620c of door radius of turn can be greater than the gradient of the inboard inclined surface 620d of door radius of turn.Therefore, can minimize the breech lock 51 that when breech lock 51 just is being inserted in the patchhole 610, trends towards producing and the friction between the patchhole 610.

Simultaneously, preferably, exist from extend back mobile rib 630 (see figure 2)s that prevent of certain-length of the end points at patchhole 610 rear portions of inclined surface 620.That is, the mobile rib 630 that prevents can be set to support a side of the breech lock 51 that is so inserted.In view of the above, because being moved, breech lock 51 prevents that rib 630 is fixing, so can minimize the vibration of the breech lock 51 that when driving washing machine, produces.

As already described, washing machine of the present invention has following advantage.

At first, the user is easy to open and close door, thereby allows to provide a kind of easy to use washing The clothing machine.

The second, the machine door switch allows to provide a kind of the have durability of enhancing and washing of security The clothing machine.

The 3rd, because can even easily open door from the inside of cylinder, so can provide A kind of washing machine, this washing machine can prevent owing to the accident that the security that neglects child causes is sent out Give birth to.

To those skilled in the art, it is evident that and to make in the present invention Various modifications and change and do not depart from spirit of the present invention or scope. Therefore, expectation the present invention Contain modification of the present invention and change, as long as they belong to claims and equivalents thereof Scope.
