Description

Technical Field

[0001] The present application relates to the technical field of door locks, and in particular to a door lock and a washing and drying machine. Background Art

[0002] When the washing and drying machine is in normal washing and drying operation, the door cover of the washing and drying machine is connected to the washing and drying machine body through the door lock to prevent the door cover from being opened at will when the washing and drying machine is working.

[0003] In the related art, the door lock of the washing machine generally adopts electromagnetic door lock. The electromagnetic door lock performs power on and off control through electromagnetic induction, that is, an electromagnetic coil and a bimetallic strip are arranged inside the door lock housing. When the power is turned on, the electromagnetic coil generates magnetism, so that one end of the bimetallic strip is connected to the static contact to achieve the power-on locking action. When the magnetism disappears, the end of the bimetallic strip connected to the static contact is separated from the static contact to achieve the unlocking action.

[0004] However, in order to achieve better locking effect and stability, the door lock of the washing machine in the related art has the defects of being too complicated in structure and increasing the difficulty of user operation. Summary of the invention

[0005] The purpose of the present application is to provide a door lock and a washing and drying machine, which can simplify the door lock structure and reduce the difficulty of user operation while ensuring that the door lock has good locking effect and stability.

[0006] The embodiment of the present application provides a door lock, comprising:

[0007] The shell has an opening;

[0008] An operating mechanism, located outside the housing, having a latch that can be rotated into the housing along the opening;

[0009] A lock core mechanism is located in the housing and can abut against the door bolt rotated into the housing. After the abutment, when the door bolt rotates a corresponding angle along the rotation direction, the rotation path of the door bolt is blocked;

[0010] A locking mechanism is fixed in the shell and connected to the lock core mechanism. When the door latch causes the lock core mechanism to rotate a corresponding angle, the lock core mechanism is locked by electromagnetic force generated by electromagnetic induction, so that the lock core mechanism restricts the door latch from rotating out. When an external unlocking command is received, the lock core mechanism is unlocked, so that the door latch can rotate out of the shell in a direction opposite to the rotation direction.

[0011] In some embodiments, the operating mechanism further includes:

[0012] handle;

[0013] A connecting rod is used to connect the door bolt and the handle respectively, so that the door bolt rotates along with the handle.

[0014] In some embodiments, the lock core mechanism comprises:

[0015] The lock cylinder is rotatably assembled, and after abutting against the door bolt, when the door bolt rotates a corresponding angle along the rotation direction, it blocks the rotation path of the door bolt and triggers the locking mechanism to perform the locking operation;

[0016] a first locking member, which is movably assembled and connected to the locking mechanism, is driven by the electromagnetic force generated by the locking mechanism through electromagnetic induction and moves to a locking position when the locking mechanism performs a locking operation, locks the lock core when moving to the locking position, and is reset when the locking mechanism ends the locking operation;

[0017] The second locking piece is rotatably assembled and connected to the locking mechanism. When the first locking piece moves to the locking position, it rotates a corresponding angle and triggers the locking mechanism to maintain the locking operation. When the locking operation ends, it is driven and reset by the electromagnetic force generated by electromagnetic induction by the locking mechanism.

[0018] In some embodiments, the first locking member is provided with a limiting hole, the lock core and the second locking member are connected via a shaft sleeve, and the first locking member is inserted and assembled with the shaft sleeve through the limiting hole.

[0019] In some embodiments, the lock core has a latch groove extending from an outer side to an inner side, and a first abutment portion and a second abutment portion are respectively formed on both sides of the latch groove, a third abutment portion is formed on the outer edge of the first abutment portion, and a fourth abutment portion is formed between a position facing away from the latch groove and the second abutment portion. When the door bolt is rotated in, it is abutted by the first abutment portion, and after abutting with the door bolt, it rotates along the rotation direction with the door bolt by a corresponding angle. When it rotates along the rotation direction with the door bolt by a corresponding angle, the second abutment portion blocks the rotation path of the door bolt, and the third abutment portion abuts and triggers the locking mechanism. After the first locking member is displaced, it abuts against the first locking member through the fourth abutment portion.

[0020] In some embodiments, the first locking member has a fifth abutment portion and a sixth abutment portion formed at both ends, respectively, and a limiting inclined surface is formed on the inner side of the fifth abutment portion. The locking mechanism is connected via the fifth abutment portion, and before the locking mechanism performs a locking operation, the second locking member that is rotated to the position where the locking mechanism is not triggered is abutted and locked by the fifth abutment portion. When the second locking member is displaced to the locking position, the second locking member is released to the limiting inclined surface and the lock core is abutted and locked by the sixth abutment portion on the side close to the limiting hole.

[0021] In some embodiments, the second locking member has a seventh abutment portion formed at one end and is connected to the locking mechanism at the other end. An eighth abutment portion is formed at an inner interval of the seventh abutment portion, and is connected to a tension spring that can cause the eighth abutment portion to trigger the locking mechanism. The second locking member abuts against the first locking member through the seventh abutment portion. Before the first locking member moves to the locking position, it is acted upon by the electromagnetic force generated by the locking mechanism through electromagnetic induction and does not trigger the locking mechanism. When the first locking member moves to the locking position, the locking mechanism is triggered by the tension of the tension spring.

[0022] In some embodiments, the locking mechanism comprises:

[0023] Controller;

[0024] a first micro switch, which is triggered when the lock core rotates with the door bolt at a corresponding angle, and causes the controller to generate a locking signal when triggered;

[0025] a second micro switch, which is triggered when the second locking member rotates to a corresponding angle, and when triggered, causes the controller to continue to generate the locking signal;

[0026] a first electromagnet connected to the first locking member, and causing the first locking member to move to a locking position by generating an electromagnetic force through electromagnetic induction when receiving the locking signal;

[0027] The second electromagnet is connected to the second locking member, and drives the second locking member to reset through the electromagnetic force generated by electromagnetic induction when the controller stops generating the locking signal.

[0028] In some embodiments, the door lock further includes:

[0029] A limiting wedge is fixed in the shell and is located beside the lock core mechanism. A turning-in inclined surface is formed near the end where the door bolt is turned in, which extends obliquely along the turning-in path of the door bolt. Damping is provided through surface contact when the door bolt is turned in, and a locking groove that matches the shape of the door bolt is formed close to the position where the door bolt is locked.

[0030] An embodiment of the present application also provides a washing machine, comprising the above-mentioned door lock.

[0031] The beneficial effects of the present application are as follows: an operating mechanism, a lock core mechanism and a locking mechanism are provided. By using the operating mechanism to make the door bolt rotate in and contact the lock core mechanism, the lock core mechanism is rotated to a corresponding angle, which can trigger the locking mechanism to lock the lock core mechanism through the electromagnetic force generated by electromagnetic induction, so that the lock core mechanism restricts the door bolt from rotating out. When the lock core mechanism receives an external unlocking command, the lock core mechanism is unlocked, so that the door bolt can be rotated out of the housing in a direction opposite to the rotation direction, so that the door lock has good locking effect and stability, while simplifying the door lock structure and reducing the difficulty of user operation.

[0042] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] It should be noted that the terms "first", "second", "third", "fourth", etc. (if any) in the specification of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0045] The embodiment of the present application also provides a door lock.

[0046] Combined with reference Figure 1 and Figure 2 In one embodiment, the door lock includes a housing 1, an operating mechanism 2, a lock core mechanism 3 and a locking mechanism 4. The housing 1 has an opening, the operating mechanism 2 is located outside the housing 1, the lock core mechanism 3 and the locking mechanism 4 are both located inside the housing 1, and a mounting seat 11 is provided inside the housing 1, and the lock core mechanism 3 and the locking mechanism 4 are assembled on the mounting seat 11.

[0047] The operating mechanism 2 has a door bolt 21 that can be rotated into the housing 1 along the opening. The lock core mechanism 3 can abut against the door bolt 21 rotated into the housing 1, and after abutting, when the door bolt 21 rotates a corresponding angle in the rotation direction, the rotation-out path of the door bolt 21 is blocked. The locking mechanism 4 is connected to the lock core mechanism 3, and when the door bolt 21 causes the lock core mechanism 3 to rotate a corresponding angle, the electromagnetic force generated by electromagnetic induction locks the lock core mechanism 3, so that the lock core mechanism 3 restricts the door bolt 21 from rotating out, and unlocks the lock core mechanism 3 when receiving an external unlocking command, so that the door bolt 21 can rotate out of the housing 1 in the direction opposite to the rotation-in direction.

[0048] In an application scenario, the operating mechanism 2 is mounted on a door, and the housing 1 is mounted on a door frame. When the door is closed, the operating mechanism 2, the lock core mechanism 3, and the locking mechanism 4 perform an interlocking operation.

[0049] Specifically, when the door latch 21 of the operating mechanism 2 is rotated into the shell 1 and abuts against the lock core mechanism 3, the lock core mechanism 3 can continue to rotate a corresponding angle along the rotation direction with the door latch 21. When the lock core mechanism 3 rotates a corresponding angle along the door latch 21, the lock core mechanism 3 blocks the rotation path of the door latch 21 and triggers the locking mechanism 4 at the same time. The locking mechanism 4 locks the lock core mechanism 3 through the electromagnetic force generated by electromagnetic induction, so that the lock core mechanism 3 restricts the door latch 21 from rotating out, completing the interlocking operation. When receiving an external unlocking command, the locking mechanism 4 cancels the external force locking the lock core mechanism 3, so that the door latch 21 can rotate out of the shell 1 in the direction opposite to the rotation direction, completing the unlocking operation.

[0050] The following is further described in conjunction with specific embodiments.

[0051] Combined with reference Figure 1 and Figure 3 The operating mechanism 2 at least includes a handle 22 and a connecting rod 23.

[0052] The connecting rod 23 connects the bolt 21 and the handle 22 respectively, so that the bolt 21 rotates with the handle 22. The handle 22 is connected to one end of the connecting rod 23 through a copper nut sleeve, and the bolt 21 is connected to the other end of the connecting rod 23. The bolt 21 is also provided with a copper sleeve. The handle 22 and the bolt 21 are perpendicular to the connecting rod 23, and the handle 22 and the bolt 21 are parallel to each other and face opposite directions.

[0053] In an application scenario, the connecting rod 23 is rotatably connected to the inside of the door, and the handle 22 and the latch 21 are respectively located at the front and rear sides of the door. The user operates the handle 22 to rotate the latch 21.

[0054] Combined with reference Figure 1 , Figure 2 and Figure 4 The lock core mechanism 3 includes a lock core 31 , a first locking member 32 and a second locking member 33 .

[0055] The lock core 31 can be rotatably assembled, the first locking member 32 can be movably assembled, and the second locking member 33 can be rotatably assembled. In a specific embodiment, the first locking member 32 is provided with a limiting hole, the lock core 31 and the second locking member 33 are connected through a sleeve, and the first locking member 32 is inserted and assembled with the sleeve through the limiting hole.

[0056] When the lock cylinder 31 contacts the door bolt 21 and the door bolt 21 rotates a corresponding angle in the rotation direction, the rotation path of the door bolt 21 is blocked and the locking mechanism 4 is triggered to perform the locking operation. The first locking member 32 is connected to the locking mechanism 4, and is driven by the electromagnetic force generated by the electromagnetic induction of the locking mechanism 4 and moves to the locking position when the locking mechanism 4 performs the locking operation. When the lock cylinder 31 is moved to the locking position, it is locked and reset when the locking mechanism 4 ends the locking operation. The second locking member 33 is connected to the locking mechanism 4, and rotates a corresponding angle when the first locking member 32 moves to the locking position and triggers the locking mechanism 4 to maintain the locking operation. When the locking operation ends, it is driven by the electromagnetic force generated by the electromagnetic induction of the locking mechanism 4 and resets.

[0057] The lock core 31 is rotatably connected to a sleeve and is assembled on the mounting seat 11 through the sleeve. The mounting seat 11 is provided with a barrel groove. The door bolt 21 rotated into the housing 1 passes through the barrel groove and abuts against the lock core 31. When the door bolt 21 further rotates in the rotation direction, the lock core 31 follows the rotation until the lock core 31 rotates with the door bolt 21 by a corresponding angle. The lock core 31 triggers the locking mechanism 4 to perform the locking operation, and the lock core 31 blocks the rotation path of the door bolt 21. The first locking member 32 is inserted and assembled with the sleeve through the limiting hole. When it moves, it is limited by the limiting hole and the sleeve. When the lock core 31 triggers the locking mechanism 4, the locking mechanism 4 drives the first locking member 32 to move to the locking position through the electromagnetic force generated by electromagnetic induction. When the first locking member 32 moves to the locking position, it abuts against the lock core 31 to lock the lock core 31, so that the lock core 31 cannot rotate in the rotation direction of the door bolt 21, thereby locking the door bolt 21. The second locking member 33 is rotatably connected to the shaft sleeve where the lock core 31 is located. Before the first locking member 32 is displaced to the locking position, it abuts against the second locking member 33 to limit the second locking member 33 from triggering the locking mechanism 4. When the first locking member 32 is displaced to the locking position, the abutting position of the first locking member 32 changes due to the displacement, so that the second locking member 33 can rotate to a corresponding angle and trigger the locking mechanism 4, so that the locking mechanism 4 maintains the locking operation. At the end of the locking operation, the locking mechanism 4 resets the first locking member 32 and drives the second locking member 33 to reset through the electromagnetic force generated by electromagnetic induction. The first locking member 32 again abuts against the second locking member 33 to limit the triggering of the locking mechanism 4. At the same time, the first locking member 32 releases the lock core 31, so that the bolt 21 can drive the lock core 31 to rotate in the rotation direction, and completes the unlocking when rotating out of the housing 1.

[0058] Combined with reference Figure 1 , Figure 2 , Figure 4 and Figure 5 In one embodiment, the lock core 31 is provided with a latch groove 311 from an outer side to an inner side, and a first abutting portion 312 and a second abutting portion 313 are formed on both sides of the latch groove 311, a third abutting portion 314 is formed on the outer edge of the first abutting portion 312, and a fourth abutting portion 315 is formed between a position facing away from the latch groove 311 and the second abutting portion 313. When the door bolt 21 is rotated in, the lock core 31 abuts through the first abutting portion 312, and after abutting with the door bolt 21, it rotates along the rotation direction of the door bolt 21 by a corresponding angle. When the door bolt 21 rotates along the rotation direction by a corresponding angle, the second abutting portion 313 blocks the rotation path of the door bolt 21, and abuts and triggers the locking mechanism 4 through the third abutting portion 314, and abuts against the first locking member 32 through the fourth abutting portion 315 after the first locking member 32 is displaced.

[0059] A through hole is provided near the center of the lock core 31, and a sleeve is inserted and connected through the through hole so as to be rotatably assembled on the mounting seat 11. The lock core 31 is generally an elliptical structure, and a latch groove 311 is provided on one of the outer sides of the lock core 31. The latch groove 311 extends from the outer side to the inside of the lock core 31 to accommodate the door bolt 21 that is rotated in. The side walls on the left and right sides of the latch groove 311 respectively form a first abutment portion 312 and a second abutment portion 313, and a third abutment portion 314 is formed on the outer edge of the first abutment portion 312. The first abutment portion 312 is used to abut against the door bolt 21 that is rotated in, the second abutment portion 313 is used to abut against the door bolt 21 that is rotated out to limit the door bolt 21 from rotating out, and the third abutment portion 314 is used to trigger the locking mechanism 4. Before the bolt 21 is rotated into the housing 1, the lock core 31 is rotated to an angle where the bolt 21 can be rotated into the latch groove 311. For example, a spring cooperates with the lock core 31 to push the lock core 31 to an angle opposite to the bolt 21 in the opening direction of the latch groove 311. When the bolt 21 is rotated into the latch groove 311, the bolt 21 can abut against the first abutting portion 312 and further rotate in the rotation direction, so that the lock core 31 rotates with the bolt 21 until it rotates to a corresponding angle and triggers the locking mechanism 4 through the third abutting portion 314. When unlocking, the lock core 31 can be reset as the bolt 21 is rotated out, or reset under the action of the spring, so that the bolt 21 can be rotated out of the housing 1.

[0060] The lock core 31 has a fourth abutment portion 315 formed between the position facing away from the latch groove 311 and the second abutment portion 313. When the lock core 31 abuts against the first transmission member through the fourth abutment portion 315, it cannot be reset due to the restriction of the first transmission member. When the third abutment portion 314 triggers the locking mechanism 4, the first transmission member moves to the locking position, for example, the first transmission member moves a corresponding distance toward the lock core 31 and abuts against the fourth abutment portion 315, so that the lock core 31 cannot be reset, and the door bolt 21 cannot be rotated out due to the restriction of the second abutment portion 313, thereby locking the door bolt 21.

[0061] Combined with reference Figure 1 , Figure 2 , Figure 4 and Figure 6 In one embodiment, the first locking member 32 has a fifth abutting portion 321 and a sixth abutting portion 322 at both ends, respectively. A limiting inclined surface 323 is formed on the inner side of the fifth abutting portion 321. The locking mechanism 4 is connected via the fifth abutting portion 321, and the first locking member 32 is fixed to the housing 1 via the sixth abutting portion 322 and a tension spring. Before the locking mechanism 4 performs the locking operation, the first locking member 32 abuts against and locks the second locking member 33 that rotates to the position where the locking mechanism 4 is not triggered, via the fifth abutting portion 321. When the second locking member 33 is displaced to the locking position, the second locking member 33 is released to the limiting inclined surface 323 and the side of the sixth abutting portion 322 close to the limiting hole abuts against and locks the lock core 31.

[0062] A limiting hole is provided near the center of the first locking member 32, and the sleeve connecting the lock core 31 and the second locking member 33 is inserted and assembled through the limiting hole. The first locking member 32 is generally a long strip structure, and a fifth abutment portion 321 and a sixth abutment portion 322 are formed at both ends of the first locking member 32, respectively, and a limiting inclined surface 323 is formed between the fifth abutment portion 321 and the limiting hole. Among them, the fifth abutment portion 321 is used to limit the second locking member 33 that has not triggered the locking mechanism 4, the sixth abutment portion 322 is used to limit the lock core 31 after rotating with the door bolt 21 at a corresponding angle, and the limiting inclined surface 323 is used to limit the second locking member 33 that triggers the locking mechanism 4, and the width of the limiting inclined surface 323 gradually increases from the end away from the fifth abutment portion 321 to the end close to the fifth abutment portion 321. Before the lock core 31 triggers the locking mechanism 4, the first locking piece 32 abuts against one end of the second locking piece 33 through the side of the fifth abutment portion 321 close to the sixth abutment portion 322 to limit the second locking piece 33 from rotating to trigger the locking mechanism 4, and a gap is left between the sixth abutment portion 322 and the lock core 31, so as not to have a restrictive effect on the lock core 31. When the lock cylinder 31 triggers the locking mechanism 4, the locking mechanism 4 generates a corresponding external force through electromagnetic induction to drive the first locking member 32 to move to the locking position. The first locking member 32 moved to the locking position switches to abut against one end of the second locking member 33 through the limiting inclined surface 323. Since the width of the limiting inclined surface 323 is smaller at the end away from the fifth abutting portion 321 and larger at the end close to the fifth abutting portion 321, the limiting inclined surface 323 abuts against the second locking member 33 that rotates to a corresponding angle and triggers the locking mechanism 4. At the same time, the sixth abutting portion 322 moves with the first locking member 32 to reach a position where it can abut against the lock cylinder 31. By abutting against the lock cylinder 31, the lock cylinder 31 is restricted from rotating and resetting. When unlocking, the locking mechanism 4 cancels the external force applied to the first locking member 32, and the first locking member 32 is reset under the action of the tension spring.

[0063] Combined with reference Figure 1 , Figure 2 , Figure 4 and Figure 7 In one embodiment, the second locking member 33 has a seventh abutting portion 331 formed at one end and is connected to the locking mechanism 4 at the other end. An eighth abutting portion 332 is formed at an inner interval of the seventh abutting portion 331, and is connected to a tension spring that can cause the eighth abutting portion 332 to trigger the locking mechanism 4. The seventh abutting portion 331 abuts against the first locking member 32, and before the first locking member 32 moves to the locked position, it is acted upon by the electromagnetic force generated by the locking mechanism 4 through electromagnetic induction and does not trigger the locking mechanism 4. When the first locking member 32 moves to the locked position, the locking mechanism 4 is triggered by the tension of the tension spring.

[0064] A through hole is provided near the center of the second locking member 33, and the second locking member 33 is connected with a sleeve through the through hole so as to be rotatably assembled on the mounting seat 11. The second locking member 33 is generally in an arc-shaped structure, and a seventh abutment portion 331 is formed at one end of the second locking member 33, and the other end of the second locking member 33 is connected to the locking mechanism 4. When the first locking member 32 is displaced to the locking position, the second locking member 33 can rotate around the through hole provided when the locking mechanism 4 is driven by the electromagnetic force generated by electromagnetic induction, and after rotating to a corresponding angle, the locking mechanism 4 is triggered again and abuts against the first locking member 32 through the seventh abutment portion 331, and is no longer rotated due to the limiting effect of the first locking member 32. The second locking member 33 is spaced apart from the inner side of the seventh abutment portion 331 to form an eighth abutment portion 332. When the second locking member 33 rotates to a corresponding angle, the eighth abutment portion 332 abuts against the locking mechanism 4 and triggers the locking mechanism 4.

[0065] Combined with reference Figure 1 , Figure 2 , Figure 4 and Figure 8 In one embodiment, the locking mechanism 4 includes a controller 41 and a first micro switch 42 , a second micro switch 43 , a first electromagnet 44 and a second electromagnet 45 electrically connected to the controller 41 .

[0066] The first micro switch 42 is triggered when the lock cylinder 31 rotates with the door bolt 21 to a corresponding angle, and when triggered, the controller 41 generates a locking signal. The second micro switch 43 is triggered when the second locking member 33 rotates to a corresponding angle, and when triggered, the controller 41 continues to generate a locking signal. The first electromagnet 44 is connected to the first locking member 32, and when receiving the locking signal, the electromagnetic force generated by electromagnetic induction causes the first locking member 32 to move to the locking position. The second electromagnet 45 is connected to the second locking member 33, and when the controller 41 stops generating the locking signal, the electromagnetic force generated by electromagnetic induction drives the second locking member 33 to reset.

[0067] When the lock core 31 rotates with the door bolt 21 at a corresponding angle, the lock core 31 triggers the first micro switch 42 by contacting with the first micro switch 42, so that the first micro switch 42 is closed. When the controller 41 detects that the first micro switch 42 is closed, it generates a locking signal to the first electromagnet 44. The first electromagnet 44, which receives the locking signal, drives the first locking member 32 to move to the locked position through the electromagnetic force generated by electromagnetic induction. When the first locking member 32 moves to the locked position, the second locking member 33 rotates at a corresponding angle and contacts with the second micro switch 43. The second locking member 33 triggers the second micro switch 43 by contacting with the second micro switch 43. The triggered second micro switch 43 is closed. When the controller 41 detects that the second micro switch 43 is closed, it continues to generate a locking signal, so that the first locking member 32 is maintained in the locked position. When unlocking, the controller 41 outputs corresponding control signals to the first electromagnet 44 and the second electromagnet 45, so that the first electromagnet 44 drives the first locking member 32 to reset, and the second electromagnet 45 drives the second locking member 33 to reset through the electromagnetic force generated by electromagnetic induction.

[0068] Combined with reference Figure 1 , Figure 2 and Fig. 9 In one embodiment, the door lock further includes a limiting wedge 5.

[0069] The limiting wedge block 5 is fixed in the shell body 1 and is located beside the lock core mechanism 3. An end of the limiting wedge block 5 close to the door bolt 21 is formed with a turning-in inclined surface 51 extending obliquely along the turning-in path of the door bolt 21, providing damping through surface contact when the door bolt 21 is turned in, and a locking groove 52 adapted to the shape of the door bolt 21 is formed close to the position where the door bolt 21 is locked.

[0070] In a specific embodiment, the limiting wedge block 5 is made of nylon.

[0071] The limiting wedge 5 is assembled on the mounting seat 11 and arranged opposite to the lock core mechanism 3, and is used to provide damping through surface contact when the door bolt 21 is rotated, so that the user can intuitively feel the interlocking operation. The limiting wedge 5 is provided with a turning-in inclined surface 51, and the width of the turning-in inclined surface 51 gradually increases from the center position away from the limiting wedge 5 to the center position close to the limiting wedge 5. When the door bolt 21 is rotated into the housing 1 and contacts the limiting wedge 5, it first passes through the turning-in inclined surface 51 and continues to rotate along the turning-in inclined surface 51 until it abuts against the lock core mechanism 3. The turning-in inclined surface 51 can provide assistance when the door bolt 21 is not aligned with the lock core mechanism 3, so that the door bolt 21 is gradually aligned with the lock core mechanism 3 during the rotation process. When the door bolt 21 rotates to the locking mechanism 4 to lock the lock core mechanism 3, the position of the door bolt 21 matches the opening position of the locking groove 52, so that the damping provided by the limit wedge 5 is reduced when the door bolt 21 is locked. The user can intuitively feel whether the interlocking operation has been completed by feeling the change in damping.

[0072] Combined with reference Figure 1 , Figure 2 and Fig.10 The embodiment of the present application also provides a washing and drying machine, which includes the door lock mentioned above, and the door lock is installed on the cover of the washing and drying machine. The specific structure of the door lock refers to the above embodiment. Since the washing and drying machine provided by the embodiment of the present application adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0073] In summary, the door lock and washing and drying machine provided in the embodiments of the present application are provided with an operating mechanism, a lock core mechanism and a locking mechanism. By using the operating mechanism to make the door latch rotate in and contact the lock core mechanism, the lock core mechanism is rotated to a corresponding angle, which can trigger the locking mechanism to lock the lock core mechanism through the electromagnetic force generated by electromagnetic induction, so that the lock core mechanism restricts the door latch from rotating out. When the lock core mechanism receives an external unlocking command, the lock core mechanism is unlocked, so that the door latch can be rotated out of the shell in a direction opposite to the rotation direction, so that the door lock has good locking effect and stability, simplifies the door lock structure and reduces the difficulty of user operation.

[0074] It should be understood that in the present application, "at least one (item)" means one or more, and "plurality" means two or more. "And / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0075] The preferred embodiments of the present invention are described above with reference to the accompanying drawings, but the scope of the rights of the present invention is not limited thereto. Any modification, equivalent substitution and improvement made by a person skilled in the art without departing from the scope and essence of the present invention should be within the scope of the rights of the present invention.
