Description

Technical Field

[0001] The present invention relates to the technical field of door locks, and particularly relates to a split-type door lock system. Background Art

[0002] In the prior art, traditional electronic door locks cannot be installed on rotating components. Since the electronic control part of the electronic door lock is connected with wires, when the rotating component rotates at a high speed, if the traditional electronic door lock is installed on the rotating component, the wires will be entangled, posing a safety hazard. On the other hand, functions such as electronic detection cannot be realized either. When installing a door lock on a rotating component in the traditional way, only a manually pressed unlocking door lock can be used. Therefore, there is an urgent need for a door lock structure in which the locking component and the electronic control component are separately arranged, so that the locking component can rotate relative to the control component. Summary of the Invention

[0003] The purpose of the present invention is to provide a split-type door lock system in which the control component and the locking component are separately arranged, having the effects of avoiding wire entanglement, high safety, and automatic unlocking.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions: A split-type door lock system includes a separately arranged door lock body and an electronic control device; a lock hook is rotatably arranged in the door lock body through a rotating shaft, a lock hole for inserting a door hook is formed on the door lock body, and the lock hook is in locking cooperation with the door hook;

[0005] An unlocking component is further arranged in the door lock body, and the unlocking component includes a first unlocking block slidably arranged in the door lock body, and the first unlocking block is in a blocking cooperation with the lock hook;

[0006] The lock hook is provided with a reset elastic member, and the reset elastic member drives the lock mouth of the lock hook to always have a movement tendency towards the lock hole;

[0007] The electronic control device includes a housing, a driving component and a push rod, the push rod is slidably arranged in the housing, the driving component drives the push rod to slide and stretch relative to the housing, and when the push rod extends, it is in a pushing cooperation with the first unlocking block;

[0008] When the driving component drives the push rod to push the first unlocking block to displace, the first unlocking block moves away from the lock hook, and the lock hook can rotate to unlock the door hook.

[0009] By adopting the above technical solution, during assembly, the door lock body is installed on the rotating component, the electric control device is installed on the fixed component, and the door hook is correspondingly installed on the door body of the rotating component. In the initial state (door closed state), the door hook installed on the door body is inserted into the lock hole and is in locking cooperation with the lock hook; when automatically unlocking and opening the door, the rotating component drives the door lock body to rotate to the corresponding position of the electric control device and stop. The driving component drives the push rod to extend out of the housing, and the front end of the push rod pushes the first unlocking block to move into the door lock body, so that the first unlocking block no longer has a blocking and matching effect on the lock hook. The lock hook can automatically rotate towards the lock hole under the elastic force of the reset elastic member, and the process of automatic unlocking after rotating into place can be realized. In this way, the door lock body and the electric control device are separately arranged. Compared with the integral arrangement in the prior art, the door lock body that does not require electrical connection can be installed on the rotating component, and the electric control device that requires electrical connection can be installed on the fixed component, avoiding wire entanglement, thereby improving safety. In addition, an electric control type automatic unlocking can be achieved through the push rod.

[0010] A further setting of the present invention is that: a wireless sensing device is further provided between the door lock body and the electric control device. The wireless sensing device includes a magnetic induction component and a receiver. The magnetic induction component is rotatably arranged in the door lock body, and the magnetic induction component and the lock hook are in transmission cooperation through a transmission structure. The receiver is fixedly installed in the electric control device; the magnetic induction component is further provided with a first reset torsion spring, and the first reset torsion spring drives the magnetic induction component to rotate and reset.

[0011] When the lock hook acts on the magnetic induction component through the transmission structure, it drives the magnetic induction component to rotate; when the lock hook moves away from the magnetic induction component, the magnetic induction component rotates and resets under the action of the first reset torsion spring.

[0012] By adopting the above technical solution, during the locking process when the door hook is inserted into the lock hook, it pushes the lock hook to rotate towards the magnetic induction component. The lock hook drives the magnetic induction component to rotate relative to the door lock body through the transmission structure, that is, relative to the receiver. When a specific position of the magnetic induction component corresponds to the receiver, the receiver can receive a signal indicating the door closed state and control the operation of the electrical appliance; when unlocking, the unlocking component drives the lock hook to unlock, and under the elastic force of the reset elastic member, the lock hook moves away from the magnetic induction component. The magnetic induction component rotates and resets in the reverse direction under the action of the first reset torsion spring. At this time, the receiver no longer senses the signal of the magnetic induction component, and the operation of the electrical appliance can be controlled to stop and the door open state can be displayed. In this way, wireless induction can be realized between the door lock body and the electric control device, the door open or closed state can be displayed, and the rotary magnetic induction component does not require much space to be reserved, making the overall structure more compact and the volume smaller, which is convenient for flexible and adjustable installation.

[0013] A further setting of the present invention is that the magnetic induction component includes a magnetic support and a magnetic block. The magnetic support is rotatably arranged inside the door lock body, and the magnetic block is fixedly installed on the magnetic support; the transmission structure includes an arc-shaped transmission guiding surface arranged on the outer wall of the magnetic support, and the arc-shaped transmission guiding surface is in transmission cooperation with the locking hook.

[0014] By adopting the above technical solution, when the locking hook acts on the arc-shaped transmission guiding surface along the axial direction of the magnetic support, the whole magnetic support can be driven to rotate circumferentially; the two ends of the magnetic block are respectively an S pole and an N pole. When the magnetic support rotates relative to the door lock body, the magnetic block can be driven to rotate.

[0015] A further setting of the present invention is that a first reset spring is arranged inside the door lock body, and the first reset spring always drives the first unlocking block to have a movement tendency to extend out of the door lock body; the first unlocking block is provided with an avoidance notch and a blocking part. When the first reset spring is in an extended state, the blocking part is in a blocking cooperation with the locking hook, and the locking hook is in a locked state. When the first reset spring is in a compressed state, the avoidance notch is in an avoidance cooperation with the locking hook, and the locking hook is in an unlocked state.

[0016] By adopting the above technical solution, in the initial state, the bottom of the locking hook abuts against the blocking part of the first unlocking block, so that the locking hook cannot rotate arbitrarily and is locked; when unlocking, the push rod pushes the first unlocking block to press into the door lock body, so that the blocking part is away from the locking hook, and the locking hook corresponds to the avoidance notch. At this time, the locking hook is no longer blocked by the blocking part and can rotate to unlock. When the door hook is inserted into the locking hook and the push rod retracts into the housing, the first unlocking block automatically moves out of the door lock body under the elastic force of the first reset spring, so that the blocking part is re-correspondingly located below the locking hook to form a block for the locking hook.

[0017] A further setting of the present invention is that the reset elastic member is set as a second reset torsion spring sleeved on the rotating shaft. The end of the second reset torsion spring abuts against the lock shell, and the middle part of the second reset torsion spring abuts against the locking hook.

[0018] By adopting the above technical solution, the middle part of the second reset torsion spring abuts against the locking hook and the two ends abut against the door lock body, so that the acting force of the second reset torsion spring on the locking hook is more concentrated and stable.

[0019] A further setting of the present invention is that the unlocking component further includes a second unlocking block arranged inside the door lock body. The second unlocking block is in transmission cooperation with the first unlocking block through a guiding surface. The guiding surface is arranged on the second unlocking block, and the guiding surface drives the first unlocking block to move into the door lock body along the axis direction parallel to the rotating shaft, and the unlocking directions of the first unlocking block and the second unlocking block are perpendicular to each other; a second reset spring is arranged between the second unlocking block and the door lock body, and the second reset spring always drives the second unlocking block to have a movement tendency to extend out of the door lock body.

[0020] By adopting the above technical solution, in addition to the electric unlocking of the first unlocking block, the unlocking can also be performed by manually pressing the second unlocking block. The second unlocking block drives the first unlocking block to move relative to the locking hook through the guiding surface, so that the first unlocking block moves into the door lock body to unlock the locking hook. Since the unlocking directions of the first unlocking block and the second unlocking block are perpendicular to each other, the first unlocking block can be driven from different directions to achieve the unlocking process. In this way, when the unlocking position of the first unlocking block is blocked and cannot be directly unlocked, the second unlocking block can be used to achieve indirect unlocking. The multi-directional unlocking method has the effects of convenient use and double insurance.

[0021] The further setting of the present invention is that: a positioning structure is provided between the first unlocking block and the second unlocking block. After the second unlocking block is pressed into the door lock body for unlocking, the second unlocking block and the first unlocking block are mutually positioned, so that the locking hook is in a semi-unlocked state.

[0022] By adopting the above technical solution, after the second unlocking block is pressed into the door lock body, the first unlocking block locks and positions the second unlocking block through the positioning structure, and both the first unlocking block and the second unlocking block are positioned at the relatively unlocked positions to achieve semi-unlocking.

[0023] The further setting of the present invention is that: the positioning structure includes a hook portion and a positioning groove provided on the second unlocking block, and the first unlocking block is provided with a positioning portion. The hook portion and the positioning portion are in a stop fit along the direction in which the second unlocking block extends out of the door lock body, and the positioning portion is correspondingly embedded in the positioning groove; a guiding inclined surface is provided on the blocking portion of the first unlocking block, and the upper surface of the blocking portion is provided with a stop surface, and the guiding inclined surface and the stop surface are adjacently arranged.

[0024] By adopting the above technical solution, when the second unlocking block is pressed into the lock case, the door hook may be pressed down simultaneously with the second unlocking block, and the phenomenon that the door hook abuts against the locking hook and causes failure to unlock may occur. However, the above phenomenon can be avoided through the action of the guiding inclined surface. When the second unlocking block is pressed inward, under the action of the guiding surface, the first unlocking block is displaced into the lock case. When the positioning portion corresponds to the positioning groove, under the elastic force of the first return spring, the first unlocking block can be pushed to move a certain distance in the direction away from the lock case, so that the positioning portion is correspondingly embedded in the positioning groove. And the second unlocking block makes the hook portion hook on the side wall of the positioning portion under the elastic force of the second return spring. In this way, both the first unlocking block and the second unlocking block can be positioned at the unlocking position, and the guiding inclined surface is exactly located corresponding to the end face of the locking hook. When the pressing on the second unlocking block and the door hook is released, the locking hook rotates out of the lock hole under the elastic force of the second return torsion spring, so that its bottom abuts against the guiding inclined surface. The first unlocking block moves a certain distance into the lock case, the positioning portion moves away from the positioning groove, and the hook portion of the second unlocking block also disengages from the positioning portion. Under the elastic force of the second return spring, the second unlocking block can be automatically moved out of the lock case to reset, and then the first unlocking block automatically resets by moving outward under the elastic force of the first return spring.

[0025] A further setting of the present invention is that the driving component includes a synchronous motor and a transmission component. The transmission component includes a plurality of meshing gear sets and a rack. The gear sets are in transmission cooperation with the output shaft of the synchronous motor, and the rack is integrally formed on the push rod.

[0026] By adopting the above technical solution, when the synchronous motor is started, it drives the gear sets to transmit in sequence. The gear sets can drive the push rod to expand and contract relative to the housing through the rack. The movement process is relatively stable, and the control effect on the unlocking device when the push rod extends is relatively accurate. In addition, the synchronous motor rotates in an indefinite direction. Whether it is just started or when the push rod extends in place, as long as the external force moment value received by the push rod is greater than the blocking torque of the motor, the synchronous motor can reverse to drive the transmission component to move in the reverse direction, so that the push rod automatically retracts, and the reciprocating movement of the push rod can be realized. Compared with a DC motor, it can be realized without using a complex circuit switch.

[0027] A further setting of the present invention is that a microswitch is also provided in the housing. The microswitch cooperates with the push rod. An inclined surface is provided at the rear end of the push rod, and the inclined surface is arranged in the direction of the push rod retracting into the housing, and the inclined surface cooperates with the contact piece of the microswitch.

[0028] By adopting the above technical solution, when the whole push rod retracts into the housing, the rear end of the push rod abuts against the microswitch, and the signal feedback of the position of the push rod can be carried out through the microswitch.

[0029] To sum up, the present invention has the following beneficial effects:

[0030] 1. By adopting the method of separately setting the door lock body and the electric control device, compared with the integral setting in the prior art, the door lock body that does not require electrical connection can be installed on the rotating part, and the electric control device that requires electrical connection can be installed on the fixed part, avoiding wire entanglement, thereby improving safety. In addition, an electric control type automatic unlocking can be realized through the push rod;

[0031] 2. By adopting the method of setting a wireless sensing device between the door lock body and the electric control device, it can be used to real-time feedback the state of opening or closing the door, and the rotating magnetic induction component does not need to reserve much space, making the overall structure more compact and the volume smaller, which is convenient for flexible and adjustable installation;

[0032] 3. By adopting the method of installing the first unlocking block and the second unlocking block in the door lock body at the same time, when the unlocking position of the first unlocking block is blocked and cannot be directly unlocked, the second unlocking block can also be used to achieve indirect unlocking. By adopting the multi-directional unlocking method, it has the effects of convenient use and double insurance;

[0033] 4. By setting a positioning structure between the first unlocking block and the second unlocking block, both of them are in a semi-unlocked state after unlocking, and the first unlocking block and the second unlocking block will not automatically reset under the elastic force of the first return spring and the second return spring, preventing the problem that the feedback signal time is too short for the main control device to detect;

[0034] 5. By using a synchronous motor to drive the push rod to move, the push rod can move reciprocally in an indefinite direction, and the position of the push rod can also be fed back through a microswitch. Description of the Drawings

[0045] The present invention will be further described below with reference to the accompanying drawings.

[0046] A split-type door lock system, as Figure 1 shown, includes a split door lock body 1 and an electric control device 2. During assembly, the door lock body 1 can be installed on a rotating part, such as the opening of the inner barrel of a washing machine, and the electric control device 2 can be installed on a fixed part, such as the washing machine housing, and the door hook 3 is correspondingly installed on the door body of the rotating part.

[0047] As Figure 2 shown, the door lock body 1 includes a lock shell 11. A lock hook 12 is rotatably arranged in the lock shell 11 through a rotating shaft 121. The lock hook 12 is arranged in a "U" shape. A second reset torsion spring 122 is sleeved on the rotating shaft 121. The two ends of the second reset torsion spring 122 abut against the lock shell 11, and the middle part of the second reset torsion spring 122 abuts against the lock hook 12. The reset elastic member drives the lock mouth of the lock hook 12 to always have a movement tendency towards the lock hole 13. By abutting the middle part of the second reset torsion spring 122 against the lock hook 12 and the two ends against the lock shell 11, the acting force of the second reset torsion spring 122 on the lock hook 12 is more concentrated and stable. A lock hole 13 for inserting the door hook 3 is formed on the lock shell 11. The door hook 3 is inserted into the lock shell 11 through the lock hole 13 and is in locking cooperation with the lock hook 12.

[0048] As Figure 2 and Figure 3As shown, an unlocking assembly is also provided inside the lock housing 11. The unlocking assembly includes a first unlocking block 4 and a second unlocking block 5 that are slidably arranged on the door lock main body 1. The first unlocking block 4 is in a stop cooperation with the lock hook 12. The first unlocking block 4 is provided with an avoidance notch 41 and a stop portion 42. The stop portion 42 is arranged at the left end of the first unlocking block 4. The avoidance notch 41 is located in the middle of the first unlocking block 4. The upper surface of the stop portion 42 is provided with a stop surface 421, and the stop surface 421 is in a stop cooperation with the bottom of the lock hook 12. A first return spring 14 is arranged inside the lock housing 11. The first return spring 14 always drives the first unlocking block 4 to have a movement tendency to extend out of the lock housing 11. When the first return spring 14 is in an extended state, the stop portion 42 is in a stop cooperation with the bottom end of the lock hook 12, and the lock hook 12 is in a locked state. When the first return spring 14 is in a compressed state, the avoidance notch 41 is in an avoidance cooperation with the lock hook 12, and the lock hook 12 is in an unlocked state.

[0049] In the initial state, the bottom of the lock hook 12 abuts against the stop portion 42 of the first unlocking block 4, so that the lock hook 12 cannot rotate arbitrarily and is locked. When unlocking, the push rod 22 of the electric control device 2 pushes the first unlocking block 4 to press into the door lock main body 1, so that the stop portion 42 is separated from the lock hook 12, and the lock hook 12 corresponds to the avoidance notch 41. At this time, the lock hook 12 is no longer blocked by the stop portion 42 and can rotate to unlock. When the door hook 3 is inserted into the lock hook 12 and the push rod 22 retracts into the housing 21, the first unlocking block 4 automatically moves out of the door lock main body 1 under the elastic force of the first return spring 14, so that the stop portion 42 is re-correspondingly located below the lock hook 12 to form a stop for the lock hook 12.

[0050] As Figure 2-4 shown, the second unlocking block 5 is in a transmission cooperation with the first unlocking block 4 through a guide surface 51. The guide surface 51 is arranged on the second unlocking block 5. The guide surface 51 drives the first unlocking block 4 to move into the door lock main body 1 along the axis direction parallel to the rotation axis 121, and the unlocking directions of the first unlocking block 4 and the second unlocking block 5 are perpendicular to each other. A second return spring 15 is arranged between the second unlocking block 5 and the lock body. The second return spring 15 always drives the second unlocking block 5 to have a movement tendency to extend out of the lock housing 11. In addition to the electric unlocking of the first unlocking block 4, unlocking can also be performed by manually pressing the second unlocking block 5. The second unlocking block 5 drives the first unlocking block 4 to move relative to the lock hook 12 through the guide surface 51, so that the first unlocking block 4 moves into the door lock main body 1 to unlock the lock hook 12. Since the unlocking directions of the first unlocking block 4 and the second unlocking block 5 are perpendicular to each other, the first unlocking block 4 can be driven from different directions to realize the unlocking process. In this way, when the unlocking position of the first unlocking block 4 is blocked and cannot be directly unlocked, indirect unlocking can also be realized through the second unlocking block 5. By adopting the multi-directional unlocking method, it has the effects of convenient use and double insurance.

[0051] As Figure 2 and Figure 5As shown in the figure, a first limiting hole 45 is formed at the inner end of the first unlocking block 4, one end of the first return spring 14 is correspondingly limited in the first limiting hole 45, a second limiting hole 54 is provided at the inner end of the second unlocking block 5, and one end of the second return spring 15 is correspondingly limited in the second limiting hole 54. In this way, the first limiting hole 45 and the second limiting hole 54 can play a good limiting role on the first return spring 14 and the second return spring 15 to prevent deviation.

[0052] As Figure 6-9 shown in the figure, the electric control device 2 includes a housing 21, a driving component and a push rod 22. The push rod 22 is slidably arranged in the housing 21. The driving component drives the push rod 22 to slide and stretch relative to the housing 21. When the push rod 22 extends, it is in pushing cooperation with the first unlocking block 4. The driving component includes a synchronous motor 23 and a transmission component. The transmission component includes a plurality of meshing gear sets 24 and a rack 25. The gear set 24 is in transmission cooperation with the output shaft of the synchronous motor 23, and the rack 25 is integrally formed on the side wall of the push rod 22. When the driving component drives the push rod 22 to push the first unlocking block 4 to displace, the first unlocking block 4 is moved away from the locking hook 12, and the locking hook 12 can rotate to unlock the door hook 3.

[0053] After the synchronous motor 23 is started, it drives the gear sets 24 to transmit in sequence. The gear sets 24 can drive the push rod 22 to slide and stretch relative to the housing 21 through the rack 25. The movement process is relatively stable, and the control effect of the push rod 22 on the unlocking device is more accurate when the push rod 22 extends. In addition, the synchronous motor 23 rotates in an indefinite direction. Whether at the start or when the push rod 22 extends in place, as long as the external force torque value received by the push rod 22 is greater than the anti-rotation torque of the motor, the synchronous motor 23 can reverse to drive the transmission component to move in the reverse direction, so that the push rod 22 automatically retracts, and the reciprocating movement of the push rod 22 can be realized. Compared with a DC motor, it can be realized without using a complex circuit switch.

[0054] As Figure 8 and Figure 9 shown in the figure, a micro switch 6 is further arranged in the housing 21. The micro switch 6 is fixedly installed in the housing 21 through a mounting bracket 212. The micro switch 6 is in cooperation with the push rod 22. An inclined surface 221 is provided at the rear end of the push rod 22. The inclined surface 221 is arranged in the direction of the push rod 22 retracting into the housing 21, and the inclined surface 221 is in cooperation with the contact piece of the micro switch 6. When the whole push rod 22 retracts into the housing 21, the rear end of the push rod 22 abuts against the micro switch 6, and the signal feedback of the position of the push rod 22 can be carried out through the micro switch 6.

[0055] As Figure 2 and Figure 5As shown, a positioning structure is provided between the first unlocking block 4 and the second unlocking block 5. The positioning structure includes a hook portion 52 and a positioning groove 53 provided on the second unlocking block 5. The first unlocking block 4 is provided with a positioning portion 43. The hook portion 52 and the positioning portion 43 are in a stop fit along the direction in which the second unlocking block 5 extends out of the lock housing 11, and the positioning portion 43 is correspondingly embedded in the positioning groove 53. A guiding inclined surface 44 is provided on the blocking portion 42 of the first unlocking block 4, and the guiding inclined surface 44 is adjacent to the stop surface 421.

[0056] When the second unlocking block 5 is pressed into the lock housing 11, the door hook 3 may be pressed down simultaneously with the second unlocking block 5, and the phenomenon that the door hook 3 abuts against the lock hook 12 and causes failure to unlock may occur. The above phenomenon can be avoided by the action of the guiding inclined surface 44. When the second unlocking block 5 is pressed inward, under the action of the guiding surface 51, the first unlocking block 4 is displaced into the lock housing 11. When the positioning portion 43 corresponds to the positioning groove 53, under the elastic force of the first return spring 14, the first unlocking block 4 can be pushed to move a certain distance in the direction away from the lock housing 11, so that the positioning portion 43 is correspondingly embedded in the positioning groove 53. And under the elastic force of the second return spring 15, the hook portion 52 of the second unlocking block 5 hooks on the side wall of the positioning portion 43. In this way, both the first unlocking block 4 and the second unlocking block 5 can be positioned at the unlocking position, and the guiding inclined surface 44 is exactly located corresponding to the end surface of the lock hook 12. When the pressing on the second unlocking block 5 and the door hook 3 is released, the lock hook 12 rotates outward towards the lock hole 13 under the elastic force of the second return torsion spring 122, so that its bottom abuts against the guiding inclined surface 44. The first unlocking block 4 moves a certain distance into the lock housing 11, the positioning portion 43 moves away from the positioning groove 53, and the hook portion 52 of the second unlocking block 5 also disengages from the positioning portion 43. Under the elastic force of the second return spring 15, the second unlocking block 5 can be automatically moved outward to reset, and then the first unlocking block 4 is automatically moved outward to reset under the elastic force of the first return spring 14.

[0057] As Figure 2 and Figure 7As shown, a wireless sensing device is further provided between the door lock body 1 and the electric control device 2. The wireless sensing device includes a magnetic induction component 7 and a receiver 211. The magnetic induction component 7 includes a magnetic support 71 and a magnetic block 72. The magnetic support 71 is rotatably arranged in the lock case 11, and the magnetic block 72 is fixedly installed on the magnetic support 71. The magnetic induction component 7 and the lock hook 12 are in transmission cooperation through a transmission structure. The transmission structure includes an arc-shaped transmission guiding surface 711 provided on the outer wall of the magnetic support 71, and the arc-shaped transmission guiding surface 711 is in transmission cooperation with the lock hook 12. The receiver 211 is fixedly installed at a position corresponding to the magnetic induction component 7 in the housing 21 of the electric control device 2. A positioning post 712 is integrally formed on the magnetic support 71. A first return torsion spring 713 is sleeved on the positioning post 712. An insertion hole 714 is further opened on the magnetic support 71. One end of the first return torsion spring 713 is inserted into the insertion hole 714, and the other end of the first return torsion spring 713 abuts against the lock case 11. The first return torsion spring 713 drives the magnetic support 71 to rotate and reset. When the lock hook 12 acts on the arc-shaped transmission guiding surface 711 along the axial direction of the magnetic support 71, the whole magnetic support 71 can be driven to rotate circumferentially. The two ends of the magnetic block 72 are respectively an S pole and an N pole. When the magnetic support 71 rotates relative to the lock case 11, the magnetic block 72 can be driven to deflect. At this time, the receiver 211 can receive the signal and feedback the signal to the client or the main control circuit board of the electrical appliance. When the lock hook 12 unlocks and moves away from the magnetic support 71, the magnetic support 71 rotates and resets under the action of the first return torsion spring 713, and the receiver 211 no longer receives the corresponding signal, indicating that the unlocking is successful.

[0058] When the door hook 3 is inserted into the lock hook 12 during the locking process, the lock hook 12 is pushed to rotate towards the magnetic induction component 7. The lock hook 12 drives the magnetic induction component 7 to rotate relative to the lock case 11 through the transmission structure, that is, to rotate relative to the receiver 211. When a specific position of the magnetic induction component 7 corresponds to the receiver 211, the receiver 211 can receive the signal and display it as the closed door state and control the operation of the electrical appliance. When unlocking, the unlocking component drives the lock hook 12 to unlock, and under the elastic force of the reset elastic member, the lock hook 12 moves away from the magnetic induction component 7. The magnetic induction component 7 rotates and resets in the reverse direction under the action of the first return torsion spring 713. At this time, the receiver 211 no longer senses the signal of the magnetic induction component 7, and the electrical appliance can be controlled to stop operating and display the open door state. In this way, wireless induction can be realized between the door lock body 1 and the electric control device 2, and the open or closed door state can be displayed. Moreover, the rotary magnetic induction component 7 does not need to reserve much space, making the overall structure more compact and the volume smaller, which is convenient for flexible and adjustable installation.

[0059] The basic working principle of the present invention is as follows: In the initial state (door closed state), the door hook 3 installed on the door body is inserted into the lock hole 13 and is in locking cooperation with the lock hook 12; when automatically unlocking and opening the door, the rotating member drives the door lock main body 1 to rotate to the corresponding position of the electric control device 2 and stop. The driving assembly drives the push rod 22 to extend out of the housing 21. The front end of the push rod 22 pushes the first unlocking block 4 to move into the door lock main body 1, so that the first unlocking block 4 no longer has a blocking cooperation with the lock hook 12. The lock hook 12 can automatically rotate towards the lock hole 13 under the elastic force of the reset elastic member, and the process of automatic unlocking after rotating in place can be realized. In this way, the door lock main body 1 and the electric control device 2 are separately arranged. Compared with the integral arrangement in the prior art, the door lock main body 1 that does not require electrical connection can be installed on the rotating member, and the electric control device 2 that requires electrical connection can be installed on the fixed member, avoiding wire entanglement, thereby improving safety. In addition, the electric control type automatic unlocking can be realized through the push rod 22. The positions of the door lock main body 1 and the electric control device 2 always correspond to each other at the start and during unlocking.

[0060] It should be noted here that the present invention not only can be applied to the door lock of the inner barrel of a washing machine, but also can be used on other components that require rotation locking and electric control unlocking, such as a blender.

[0061] The above are only the preferred embodiments of the present invention. Therefore, all equivalent changes or modifications made according to the structures, features, and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
