[0001] This application relates to the field of clothing processing technology, and in particular to a door lock structure and clothing processing equipment. Background Technology

[0002] Clothing handling equipment, such as washing machines, includes a cabinet and a door for opening and closing the clothing handling chamber. To ensure safety, clothing handling equipment is often equipped with a detection component to monitor the door's open or closed status.

[0003] In related technologies, the detection components often adopt the structure of inductive switches such as contact switches, and require an opening on the front of the garment processing equipment for the inductive switch to sense the door. Generally, the front of the garment processing equipment also has a door lock slot for locking the door. The multiple openings on the front of the garment processing equipment affect its aesthetics.

In the second state, the portion of the locking member extending out of the clearance hole forms the locking end, and at least a portion of the locking end is located within the limiting groove.

[0050] The locking end has a polygonal cross-sectional shape.

[0051] In one embodiment, the output end of the driving member moves linearly, the locking member is located on one side of the guide slider along the direction of movement of the output end, one side of the guide slider is provided with a guide groove, and the locking member has a transmission rod, which is slidably disposed in the guide groove;

[0062] In one embodiment, the locking box is further provided with a clearance channel, and the guide slider is provided with a detection end that is movably inserted through the clearance channel;

[0063] In the first state, a portion of the limiting slider is located on the movement path of the detection end along the avoidance channel; in the second state, the limiting slider avoids the movement path of the detection end along the avoidance channel.

[0064] Secondly, embodiments of this application also provide a garment processing device, comprising:

[0065] The container includes a main body and a door. The main body has a clothing handling chamber and a loading port communicating with the clothing handling chamber. The door is movably connected to the main body to open or close the loading port.

[0066] The door lock structure described in any of the above embodiments is connected to the main body of the box, and the door hook inlet is exposed on one side of the dispensing port;

[0067] The box door has a door hook. In the first state, the box door is open and the door hook is not inserted into the door hook inlet. In the second state, the box door is closed and the door hook is inserted into the door hook inlet.

The transmission structure has a trigger end and a linkage end. The door hook can drive the trigger end to move. The trigger end and the linkage end are connected in transmission, so that when the trigger end moves, the linkage end also moves. The linkage end can act on the switch to change the on / off state of the switch.

[0069] The entry and exit of the door hook at the door hook inlet correspond to the first and second states of the transmission structure, respectively. These first and second states correspond to the open and closed states of the switch, respectively, thus corresponding to the open and closed states of the detection circuit and generating two different feedback signals. Therefore, by identifying the different signals from the detection circuit, it can be determined whether the door hook has entered the door hook inlet, i.e., whether the door is closed. In this embodiment, the transmission structure and switch are both housed within the outer casing, which has only one opening at the door hook inlet. No additional opening is needed for the detection components. Therefore, when the door lock structure is applied to clothing processing equipment, it reduces the number of openings on the exterior surface of the equipment, improving aesthetics and harmony, and enhancing product competitiveness.

[0070] Furthermore, compared to inductive switches in related technologies that use additional openings for detection, the present application embodiment, through a transmission structure in conjunction with a door hook, and its structure acting on the switching element, is less affected by external environmental interference such as magnetic fields and light, resulting in higher structural reliability.

[0083] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0084] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0085] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0086] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0087] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0088] This application provides a clothing handling device, which can be a dryer, washing machine, or washer-dryer combo, etc. The clothing handling device includes a cabinet and a door lock structure. The cabinet includes a main body and a door. The main body has a clothing handling chamber and a loading port communicating with the chamber. Users can insert clothes into the chamber through the loading port or remove clothes from the chamber through the loading port. The door is movably connected to the main body to open or close the loading port. The door lock structure is used to lock and unlock the main body and the door.

[0089] Understandably, the cabinet not only serves as the mounting base for various internal components of the garment processing equipment but also forms the main exterior surface of the equipment. In related technologies, to ensure safety, garment processing equipment often includes a detection component to monitor the door's open / closed status. This detection component typically employs a contact switch or other inductive switch structure and requires an opening on the front of the garment processing equipment for the inductive switch to detect the door. Generally, the front of the garment processing equipment also has a lock slot for locking the door. The numerous openings on the front of the garment processing equipment negatively impact its aesthetics.

[0090] To improve the aesthetics of garment processing equipment, combined with Figures 1 to 3 The door lock structure 100 proposed in this application includes a housing 10, a transmission structure 30, and a detection circuit.

[0091] In some embodiments, the door lock structure 100 is mounted on the main body of the box, and the box door is provided with a door hook. The door hook is used to cooperate with the door lock structure 100 to lock and unlock the box door to the main body. Specifically, the outer shell 10 serves as the mounting base for the transmission structure 30 and the switch assembly. The outer shell 10 is provided with a door hook inlet 115 for the door hook to extend into the internal space of the outer shell 10 through the door hook inlet 115. The surface of the outer shell 10 with the door hook inlet 115 can directly serve as part of the exterior surface of the garment handling device. For example, the outer shell 10 is located outside the loading port of the main body of the box, and the door hook is located on the side of the box door facing the main body of the box. When the box door is closed, the box door covers the outer shell 10, and the door hook extends into the door hook inlet 115. When the box door is opened, the door hook disengages from the door hook inlet 115, and the side of the outer shell 10 with the door hook inlet 115 is exposed. Alternatively, the outer shell 10 can also be mounted in the internal space of the main body of the box, and the main body of the box is provided with a through hole communicating with the door hook inlet 115, so that the door hook can pass through the through hole and the door hook inlet 115. Optionally, the outer casing 10 may be made of plastic or alloy material, and this application embodiment does not limit this.

[0092] The transmission structure 30 is movably mounted within the housing 10 and has a trigger end 311 and a linkage end 334 that are driveably connected. The trigger end 311 is configured to be driven by the door hook. For example, as the door hook extends into the housing 10 from the door hook inlet 115, it pushes the trigger end 311 to move. The drive connection between the trigger end 311 and the linkage end 334 means that when the trigger end 311 moves, the linkage end 334 moves synchronously. The movements of the trigger end 311 and the linkage end 334 can be the same or different. For example, if the trigger end 311 performs a translational movement, the linkage end 334 will also perform a synchronous translational movement; or, if the trigger end 311 performs a rotational movement, the linkage end 334 will perform a synchronous translational movement. Specifically, the transmission structure 30 can take the form of: the transmission structure 30 includes two or more moving parts, and when one moving part is moved by the trigger end 311, the linkage end 334 is moved by the transmission between multiple moving parts, such as multiple moving parts being connected by a linkage, gear set, etc.; or, the transmission structure 30 can also be a single integrated component, with the trigger end 311 and the linkage end 334 being different ends of the transmission structure 30, so that when the trigger end 311 moves, the linkage end 334 moves accordingly.

[0093] The detection circuit is electrically connected to the main control board of the garment processing equipment, and is used to feed back signals about the door's open / closed status to the main control board, so that the main control board can determine whether the door is closed. The detection circuit includes a switch 50 and a wire. The switch 50 is electrically connected to the main control board through the wire, and the switch 50 is located inside the housing 10. For example, the switch 50 has at least two states: open and closed. The correspondence between the switch 50 and the door status can be: when the switch 50 is open, the detection circuit is open, corresponding to the door being open; when the switch 50 is closed, the detection circuit is closed, corresponding to the door being closed. Alternatively, the correspondence between the switch 50 and the door status can also be: when the switch 50 is open, the detection circuit is open, corresponding to the door being closed; when the switch 50 is closed, the detection circuit is closed, corresponding to the door being open.

[0094] In one embodiment, the transmission structure 30 has a first state and a second state corresponding to the opening and closing of the cabinet door relative to the cabinet body. In the first state, the cabinet door is open, the door hook is not inserted into the door hook inlet 115, and the switch 50 is in the off state, so the detection circuit is open. In the second state, the cabinet door is closed, the door hook is inserted into the door hook inlet 115, the trigger end 311 is driven by the door hook to move, and the linkage end 334 moves accordingly, so that the switch 50 conducts the detection circuit. Thus, the detection circuit has different states in the first and second states, which can feed back different signals to the main control board. According to the correspondence between the on / off state of the detection circuit and the first and second states, it can be determined whether the cabinet door is closed, thereby facilitating subsequent control operations.

[0095] In summary, in this embodiment, the movement of the door hook through the door hook inlet 115 causes the transmission structure 30 to switch between a first state and a second state. The transmission structure 30 has a trigger end 311 and a linkage end 334. The door hook can drive the trigger end 311 to move. The trigger end 311 is connected to the linkage end 334, so that when the trigger end 311 moves, the linkage end 334 also moves. The linkage end 334 can act on the switch 50 to change the on / off state of the switch 50. That is, the entry and exit of the door hook from the door hook inlet 115 correspond to the first state and the second state of the transmission structure 30, respectively. The first state and the second state correspond to the two different states of the switch 50 being open and closed, respectively, thus corresponding to the open and closed states of the detection circuit and providing two different feedback signals. In this way, by identifying the different signals of the detection circuit, it is possible to determine whether the door hook has entered the door hook inlet 115, that is, whether the cabinet door is closed. In this embodiment, the transmission structure 30 and the switch 50 are both located inside the housing 10. The housing 10 has only one opening, the door hook inlet 115, and no additional opening is needed to set up the detection components. Therefore, when the door lock structure 100 is applied to the garment processing equipment, it can reduce the number of openings on the appearance of the garment processing equipment, improve aesthetics and coordination, and enhance product competitiveness.

[0096] Furthermore, compared to inductive switches in related technologies that use additional openings for detection, the present application embodiment, which uses a transmission structure 30 in conjunction with a door hook and acts on the switch element 50, is less affected by external environmental interference such as magnetic fields and light, resulting in higher structural reliability.

[0097] Of course, provided that the door hook and the door lock structure 100 can cooperate, the door lock structure 100 can also be set on the door of the box and the door hook can be set on the body of the box.

[0098] Obviously, in the first state, when the door is open, the switch 50 disconnects the detection circuit; in the second state, when the door is closed, the switch 50 connects the detection circuit. Thus, disconnecting the detection circuit when the door is open not only generates a signal change, facilitating the main control board's judgment of the door status, but also better ensures user safety when the door is open. Of course, the correspondence between the first and second states of the transmission structure 30 and the on / off state of the switch 50 can also be: in the first state, when the door hook is not extended into the door hook inlet 115, the switch 50 is in a connected state, and the detection circuit is open; in the second state, when the door hook extends into the door hook inlet 115, the trigger end 311 is driven by the door hook to move, and the linkage end 334 moves accordingly, causing the switch 50 to disconnect the detection circuit. This application does not limit this.

[0099] The following explanation is based on the premise that in the first state, when the cabinet door is open, the switch 50 disconnects the detection circuit, and in the second state, when the cabinet door is closed, the switch 50 connects the detection circuit.

[0100] The switching element 50 can specifically be at least one of a micro switch, a spring contact switch, a Hall switch, a reed switch, and a contact switch. When a micro switch, a spring contact switch, or a contact switch is used, the linkage terminal 334 controls the on / off state of the switching element 50 by pushing a part of the structure of the switching element 50 to move. When a Hall switch or a reed switch is used, the linkage terminal 334 is provided with a magnetic part. When the linkage terminal 334 moves, the magnetic field of the magnetic part at the Hall switch or reed switch changes, thereby controlling the on / off state of the switching element 50.

[0101] like Figure 2 As shown, in one embodiment, the switch 50 includes a first terminal 51, a second terminal 53, and a connecting spring 55. Both the first terminal 51 and the second terminal 53 are connected to the housing 10 and are spaced apart. The connecting spring 55 is telescopically disposed between the first terminal 51 and the second terminal 53. Exemplarily, one end of the connecting spring 55 is connected to the second terminal 53, while the other end is relatively free to extend and retract. The linkage end 334 acts on this freely extendable end. It should be noted that the connecting spring 55 and the second terminal 53 can be fixedly connected by adhesive, snap-fit, or through abutment connection.

[0102] For example, in the first state, the linkage end 334 compresses the connecting spring 55, causing the end of the connecting spring 55 away from the second terminal 53 to be spaced apart from the first terminal 51, the switch 50 is in the open state, and the detection circuit is broken. In the second state, the linkage end 334 moves away from the connecting spring 55, and the connecting spring 55 extends under its own elasticity until it abuts the first terminal 51, the first terminal 51 and the second terminal 53 are connected, the switch 50 is in the closed state, and the detection circuit is closed. It is worth noting that in the second state, the linkage end 334 can be completely disengaged from the connecting spring 55 to avoid interfering with the reset of the connecting spring 55.

[0103] For example, in the first state, the connecting spring 55 is in its natural state, the connecting spring 55 is spaced apart from the first terminal 51, the switch 50 is in the open state, and the detection circuit is broken; while in the second state, the linkage end 334 moves away from the connecting spring 55, the connecting spring 55 is stretched by the linkage end 334 until it connects to the first terminal 51, the first terminal 51 and the second terminal 53 are connected, the switch 50 is in the closed state, and the detection circuit is closed.

[0104] In some embodiments, the first terminal 51 includes a first fixing part 511 and a first connecting part 513 connected together, and the second terminal 53 includes a second fixing part 531 and a second connecting part 533 connected together. The first fixing part 511 and the second fixing part 531 are both fixed to the housing 10. The connecting spring 55 is located between the first connecting part 513 and the second connecting part 533, and one end is connected to the second connecting part 533, and the other end is used to abut against the first connecting part 513.

[0105] Optionally, in some structural configurations, the first connecting portion 513 and the second connecting portion 533 are generally plate-shaped, or both the first terminal 51 and the second terminal 53 are integrally plate-shaped. One side of the first terminal 51 and one side of the second terminal 53 are positioned opposite each other. Understandably, for either the first terminal 51 or the second terminal 53, the top and bottom surfaces have the largest areas in their thickness direction, while the sides are smaller surfaces surrounding the top and bottom surfaces. The connecting spring 55 is generally cylindrical and is positioned between the two opposing sides of the first terminal 51 and the second terminal 53. Due to the limited contact area between the first terminal 51 and the second terminal 53 and the connecting spring 55, parts of the connecting spring 55 are still exposed on both sides along the extension / retraction direction of the connecting spring 55. The linkage end 334 is positioned on one side of the first terminal 51 and the second terminal 53 along the extension / retraction direction of the connecting spring 55 and moves in a direction closer to or further away from the connecting spring 55. For example, in the first state, the linkage end 334 abuts against the end of the connecting spring 55 used to connect with the first terminal 51, and compresses the connecting spring 55 so that it is spaced apart from the first terminal 51, and the switch 50 is disconnected; in the second state, the linkage end 334 moves away from the connecting spring 55, causing the connecting spring 55 to release, the connecting spring 55 to reconnect with the first terminal 51, and the switch 50 is turned on. In this structure, the connecting spring 55 is telescopically provided on the plate-shaped first terminal 51 and second terminal 53, and the linkage end 334 abuts against the connecting spring 55 from the side of the first terminal 51 and second terminal 53, making the structure more compact, with high space utilization, which is beneficial to reducing the volume of the door lock structure 100.

[0106] Furthermore, there can be two linkage ends 334, respectively disposed on both sides of the first terminal 51 and the second terminal 53 along the extension and retraction direction of the connecting spring 55, so as to abut against the portions of the connecting spring 55 exposed on both sides of the first terminal 51 and the second terminal 53. In this way, by having two linkage ends 334 abut against both sides of the connecting spring 55, the stability of the connecting spring 55 can be improved, making it less prone to instability, thereby improving the reliability of the door lock structure 100.

[0107] like Figure 2 and Figure 3 As shown, in some other structural forms, at least a portion of the linkage end 334 is located on the side of the first connecting portion 513 away from the connecting spring 55. To facilitate the linkage end 334 driving the connecting spring 55, the first connecting portion 513 is provided with a connecting hole 515 through which the linkage end 334 can move. In a first state, part or all of the linkage end 334 protrudes through the connecting hole 515 to compress the connecting spring 55. In a second state, part or all of the linkage end 334 disengages from the connecting hole 515 and is located on the side of the first connecting portion 513 away from the connecting spring 55. This structure is more compact and improves space utilization.

[0108] Understandably, the connecting spring 55 can also be fixedly connected to the first terminal 51 at one end, while the other end can extend and retract to space from or abut against the second terminal 53. This embodiment does not limit this. This embodiment controls the disconnection and connection of the first terminal 51 and the second terminal 53 by controlling the extension and retraction of the connecting spring 55. The first terminal 51 and the second terminal 53 do not need to be deformed, resulting in a longer service life and greater reliability.

[0109] In other embodiments, the first terminal 51 can be a movable terminal, and the second terminal 53 can be a fixed terminal. The first terminal 51 can move relative to the second terminal 53 to achieve disconnection and connection between the two. Specifically, the first fixed part 511 and the first connecting part 513 are elastically connected, and the first connecting part 513 is located on the movement path of the linkage end 334. In the first state, the first connecting part 513 and the second connecting part 533 are spaced apart, and the switch 50 is open. In the second state, the first connecting part 513 is driven by the linkage end 334 to connect to the second connecting part 533, and the switch 50 is closed. This embodiment uses the elastic deformation of the first terminal 51 itself to control the disconnection and connection of the first terminal 51 and the second terminal 53, which makes the structure simpler and more effective.

[0110] In some embodiments, the switch 50 is located along the trigger end 311. Figure 2 As shown above in the vertical direction, the linkage end 334 can move relative to the switch 50 in the vertical direction.

[0111] Specifically, the outer casing 10 is provided with a slide or rotating cavity for the movement of the transmission structure 30. The transmission structure 30 includes a latch 31 and a transmission slider 33. The latch 31 is rotatably positioned near the door hook inlet 115 and has the aforementioned trigger end 311. The transmission slider 33 is connected to the latch 31 and has the aforementioned linkage end 334. When the trigger end 311 is touched by the door hook, the latch 31 rotates, and the rotation is converted into the up-and-down translational motion of the transmission slider 33. The rotatable latch 31 is easier for the door hook to drive and easier to touch the trigger end 311. The up-and-down translational transmission slider 33 can ensure accurate positioning to drive the first connecting part 513.

[0112] The trigger end 311 is located on the side of the latch 31 facing the door hook inlet 115, so that the door hook can directly touch the trigger end 311 after extending into the housing 10. The transmission connection between the latch 31 and the transmission slider 33 can specifically be as follows: the latch 31 also has a mating surface 313 located above itself, and one end of the transmission slider 33 slides in contact with the mating surface 313. When the latch 31 rotates, the mating surface 313 slides relative to the transmission slider 33, causing the transmission slider 33 to translate vertically. In such a case... Figure 3In the illustrated embodiment, the door hook drives the latch 31 to rotate counterclockwise, and the transmission slider 33 moves upward until the part of the transmission slider 33 that abuts against the latch 31 is at a high position in the vertical direction. At this time, the linkage end 334 moves upward and away from the connecting spring 55, and the connecting spring 55 abuts against the first terminal 51, and the first terminal 51 and the second terminal 53 are connected. A torsion spring is connected to the pivot of the latch 31. When the door hook is disengaged, the latch 31 resets clockwise under the action of the torsion spring, and the transmission slider 33 slides along the mating surface 313 and gradually moves downward. The linkage end 334 moves downward accordingly, compressing the connecting spring. In this way, the gravity of the transmission slider 33 can be used to make it move, thereby effectively ensuring the abutment relationship between the transmission slider 33 and the mating surface 313, reducing structural complexity, and improving reliability.

[0113] The mating surface 313 can be an arc-shaped mating surface 313, so that the end of the transmission slider 33 can slide smoothly relative to the locking tongue 31. Furthermore, the mating surface 313 is provided with a first limiting part 3131 and a second limiting part 3133 spaced apart. In a first state, the transmission slider 33 is limited by the first limiting part 3131, and in a second state, the transmission slider 33 is limited by the second limiting part 3133, to prevent the transmission slider 33 from disengaging from the mating surface 313 and improve structural reliability.

[0114] Of course, by adjusting the position of the trigger end 311 on the latch 31 and the cooperation relationship between the latch 31 and the transmission slider 33, it is also possible to make the latch 31 rotate clockwise when the door hook abuts against the trigger end 311 in the second state, causing the transmission slider 33 to move downward and the linkage end 334 to move downward; and in the first state, the latch 31 resets counterclockwise, the transmission slider 33 moves upward and the linkage end 334 moves upward. Further details are omitted here.

[0115] The transmission slider 33 and the locking tongue 31 can also be connected in other forms, such as linkage or gear set, so as not to rely on gravity drive. In other embodiments, the switch 50 can also be set on the side of the trigger end 311 in the horizontal direction, so as to be applicable to more types of clothing handling equipment and improve the versatility of the door lock structure 100.

[0116] Combination Figure 2 and Figure 3The transmission slider 33 is provided with a linkage groove 335. The first connecting part 513 or the entire first terminal 51 and the connecting spring 55 are all located in the linkage groove 335. The linkage end 334 is located in the linkage groove 335 and can move closer to or further away from the connecting spring 55 to disconnect or connect the detection circuit. In this way, by setting the first terminal 51, the connecting spring 55 and the linkage end 334 in the linkage groove 335, the alignment of the two can be better guaranteed, ensuring triggering stability. Furthermore, the first connecting part 513 and the second connecting part 533 can both be set in the linkage groove 335 to improve the stability of the switching element 50.

[0117] In some embodiments, the housing 10 includes a separately formed latch box 11 and a switch box 13. The latch box 11 has a door hook inlet 115, and the latch 31 is rotatably disposed within the latch box 11. The switch box 13 is connected to the latch box 11, and the switch element 50 is disposed within the switch box 13. Understandably, the internal space of the latch box 11 and the internal space of the switch box 13 are connected, and a portion of the transmission slider 33 is movably disposed within the latch box 11, while another portion is movably disposed within the switch box 13. The latch box 11 and the switch box 13 facilitate the production and assembly of the housing 10.

[0118] Furthermore, the transmission slider 33 includes a first slider 331 and a second slider 333. The first slider 331 is movably disposed within the latch box 11 and is drive-connected to the latch 31. The second slider 333 is movably disposed within the switch box 13 and has a transmission end 3331 that extends out of the switch box 13. The transmission end 3331 is drive-connected to the end of the first slider 331 away from the latch 31. Optionally, the transmission end 3331 abuts against the first slider 331 so that when the first slider 331 moves up and down, the second slider 333 moves up and down accordingly. In this way, during the production of the latch box 11 and the switch box 13, the first slider 331 and the second slider 333 can be pre-encapsulated within the latch box 11 and the switch box 13, respectively. During assembly, the transmission end 3331 is simply connected to the first slider 331, realizing the modularity of the door lock structure 100. This not only improves assembly efficiency but also allows for diverse combinations of the switch box 13 and the latch box 11, improving the structural versatility.

[0119] Of course, in other embodiments, the latch box 11 and the switch box 13 may also be an integral structure, and the first slider 331 and the second slider 333 may also be an integral structure to improve the overall structure. This is not limited here.

[0120] Combination Figure 1 and Figure 5The latch box 11 includes a mounting base 111 and a latch cover 113. The mounting base 111 and the latch cover 113 cooperate to define the internal space of the latch box 11, and the door hook inlet 115 is provided on the latch cover 113. The mounting base 111 and the latch cover 113 can be connected by snap-fit ​​connection, bolt connection, or other methods, which are not limited here.

[0121] Combination Figure 6 and Figure 7 In some embodiments, the door lock structure 100 further includes a locking component 70 and a limiting slider 60. The locking component 70 is located on one side of the latch 31, and the limiting slider 60 is movable relative to the locking component 70. Optionally, both the locking component 70 and the limiting slider 60 are mounted on the mounting base 111. In a first state, the limiting slider 60 is entirely located on one side of the latch 31. In a second state, the limiting slider 60 is limited to the rotation path of the latch 31 to prevent the latch 31 from rotating, thereby achieving a locking engagement between the latch 31 and the door hook. This helps to keep the door closed and ensures the normal operation of the clothing processing equipment's clothing processing procedure.

[0122] The locking assembly 70 includes a locking housing 71, a driving component 73, and a locking component 75. The locking housing 71 is connected to the mounting base 111. Parts of the driving component 73 and the locking component 75 are located within the locking housing 71. A limiting slider 60 is located on one side of the locking housing 71, and a clearance hole 711 is provided on the side of the locking housing 71 facing the limiting slider 60. The locking component 75 is movably inserted through the clearance hole 711 and is connected to the driving component 73. The driving component 73 can drive the locking component 75 to extend or retract from the clearance hole 711. The driving component 73 can be a combination of a coil and an iron core, using the magnetic field generated by the energized coil to drive the iron core to move; alternatively, the driving component 73 can be a motor.

[0123] Optionally, the limiting slider 60 is provided with a limiting groove 61. In the first state, the locking end 753 of the locking member 75 is retracted into the locking housing 71. In the second state, the locking end 753 extends into the limiting groove 61 to cooperate in locking the limiting slider 60 and restricting the movement of the limiting slider 60, thereby keeping the limiting slider 60 in the state of limiting the locking tongue 31 and further improving the locking reliability when the door is closed. Exemplarily, the limiting slider 60 can be driven externally or moved under the action of an elastic member. It can adopt a planar motion mode of rotation, translation, or a combination of rotation and translation. The cross-sectional shape of the locking end 753 is polygonal, and the opening shape of the limiting groove 61 is adapted to the cross-sectional shape of the locking end 753. The locking end 753 extends into the limiting groove 61 to restrict the movement of the limiting slider 60 relative to the locking housing 71.

[0124] Of course, the locking method of the limiting slider 60 and the locking member 75 can also be other forms of limiting cooperation, and this application embodiment does not limit this.

[0125] Combination Figures 7 to 9 In some embodiments, the locking assembly 70 further includes a guide slider 74 connected to the output end of the drive member 73. Optionally, the output end of the drive member 73 performs linear motion, and the locking member 75 is located on one side of the guide slider 74 along the direction of motion of the output end. A guide groove 741 is provided on one side of the guide slider 74, and the locking member 75 has a transmission rod 751 slidably disposed within the guide groove 741. A guide surface 743 is provided within the guide groove 741, which drives the transmission rod 751 to extend and retract from the retraction hole 711 during the movement of the guide slider 74. Exemplarily, the guide groove 741 opens toward the locking member 75 and extends along the direction of motion of the output end of the drive member 73, so as to... Figure 9 As shown in the top-bottom direction, the guide surface 743 is located on the lower part of the top wall of the guide groove 741 and is inclined towards the bottom. Thus, when the guide slider 74 moves upward, the transmission rod 751 approaches the guide surface 743 and is pressed down by the guide surface 743, causing the locking member 75 to extend out of the recessed hole 711, thereby locking the limiting slider 60. This embodiment uses a guide transmission method, which facilitates the structural arrangement of the locking housing 71, makes it easier to install the driving member 73, and avoids making the locking housing 71 too thick.

[0126] Combination Figure 7 In one embodiment, the locking housing 71 is further provided with a load switch assembly 90 and a connecting slider 77. The load switch assembly 90 controls the on / off state of the load circuit; the connecting slider 77 is drivenly connected to the guide slider 74 and connected to the load switch assembly 90.

[0127] Specifically, the load switch assembly 90 includes a first terminal 91, a second terminal 93, a third terminal 95, and a movable spring 97. The first terminal 91 and the second terminal 93 are respectively connected to the two terminals of the drive unit 73, and the third terminal 95 is arranged side by side with the first terminal 91 and the second terminal 93 at intervals. One end of the movable spring 97 is connected to the second terminal 93, and the other end is connected to the connecting slider 77. The first terminal 91, the second terminal 93, and the third terminal 95 are all connected to the load circuit, and the drive unit 73 is powered through the first terminal 91 and the second terminal 93.

[0128] When the driving component 73 drives the guide slider 74 to move, the connecting slider 77 moves accordingly. For example, in... Figure 7In the illustrated embodiment, the connecting slider 77 is provided with an inclined groove, and the guide slider 74 has a connecting rod that can move along the inclined groove. When the guide slider 74 moves upward, the connecting rod moves upward along the inclined groove, driving the connecting slider 77 to move to the right, so that the movable spring 97 connects to the third terminal 95. That is, in the first state, the movable spring 97 and the third terminal 95 are spaced apart, and in the second state, the connecting slider 77 drives the movable spring 97 to conduct the third terminal 95, thereby realizing the conduction of the load circuit.

[0129] As can be seen, the driving component 73 can simultaneously lock the limit slider 60 and connect the load circuit, ensuring that the load circuit is open while the door is closed, so that the clothing processing equipment can operate normally, ensuring user safety and improving the reliability of the clothing processing equipment.

[0130] Furthermore, in one embodiment, the locking box also includes a clearance channel 713, and the guide slider 74 has a detection end 745 that movably passes through the clearance channel 713. In a first state, a portion of the limiting slider 60 is located on the movement path of the detection end 745 along the clearance channel 713. In a second state, the limiting slider 60 avoids the movement path of the detection end 745 along the clearance channel 713. Exemplarily, the clearance channel 713 extends vertically. In the first state, the detection end 745 is located below the limiting slider 60 and is blocked by the limiting slider 60, preventing it from moving upwards. At this time, the driving member 73 cannot drive the guide slider 74 to move, thus preventing the load circuit from being connected. This ensures that the clothing handling device is not in operation when the box door is open, achieving double protection and further improving safety. In the second state, the detection end 745 can move along the clearance channel 713, and the driving member 73 can drive the guide slider 74 to move, thus connecting the load circuit.

[0131] The above is a detailed explanation of the door lock structure 100 of this application. It can be understood that since the clothing processing device of this application adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
