Furthermore, in the absence of external force, the lock core buckle always triggers the first switch member to cause the limit buckle to be in the first position, locking the lock core buckle and ensuring locking stability.

[0022] When unlocking, the operating member is triggered, and the operating member sends a feedback signal to the monitoring component to retract the telescopic member. When the telescopic member retracts and the limit buckle is in the second position, the limit buckle is separated from the lock core buckle, and the locking shaft is detached from the lock core buckle. The elastic member resets the lock core buckle to the unlocked position, and the lock core buckle is separated from the first switch member. By operating the operating member to separate the limit buckle from the lock core buckle, the force applied to open the door is reduced, facilitating subsequent door opening actions. The limit buckle in the second position is separated from the lock core buckle, and the lock core buckle and the limit buckle are both in a free state. When closing the door again, it is only necessary to overcome the elastic force of the elastic member to engage the locking shaft with the lock core buckle. The user can unlock and lock more conveniently and quickly, that is, conveniently and quickly open and close the machine door, enhancing the user experience. Simplifying the operating process ensures that any operator can easily understand and use it correctly, reducing the risk of misoperation. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0040] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0041] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0042] like Figure 1 and Figure 2 As shown, this embodiment provides a dryer, including an outer cover 4, a machine door 5 and the above-mentioned door lock system, the handle mechanism 1 of the door lock system is arranged on the machine door 5, and the lock core mechanism 2 of the door lock system is arranged on the outer cover 4, and the outer cover 4 and the machine door 5 are locked or unlocked by the handle mechanism 1 and the lock core mechanism 2.

[0043] like Figure 3-Figure 8 As shown, this embodiment also provides a door lock system, including a handle mechanism 1, a lock core mechanism 2, a monitoring component and an operating member. The handle mechanism 1 includes a mounting frame 11 and a locking shaft 12 provided on the mounting frame 11. The lock core mechanism 2 includes a fixed frame 21, a first switch member 22, an elastic member 23, a limit buckle 24, a lock core buckle 25 and a telescopic member 26. The limit buckle 24 and the lock core buckle 25 are respectively rotatably connected to the fixed frame 21, the first switch member 22 is provided on the fixed frame 21, the two ends of the elastic member 23 are connected to the fixed frame 21 and the lock core buckle 25, the telescopic member 26 is connected to the limit buckle 24, and the telescopic member 26 can drive the limit buckle 24 to rotate. The operating member, the telescopic member 26 and the first switch member 22 are all electrically connected to the monitoring component.

[0044] When locked, the locking shaft 12 is engaged with the lock core buckle 25, the elastic member 23 is deformed, and the lock core buckle 25 is in the locked position. The lock core buckle 25 triggers the first switch 22, which sends a signal back to the monitoring assembly, causing the telescopic member 26 to extend and the limit buckle 24 to be in the first position. The limit buckle 24 limits the lock core buckle 25. For example, the limit buckle 24 has a groove 241, and the lock core buckle 25 has a protrusion 252. The protrusion 252 can abut against the groove 241 to prevent slipping.

[0045] During operation, the handle mechanism 1 is controlled to close the door, and the locking shaft 12 moves toward the lock core buckle 25, causing it to contact the lock core buckle 25. During the closing process, the lock core buckle 25 rotates. After the door is closed, the lock core buckle 25 rotates to the locked position, engaging the locking shaft 12 and the lock core buckle 25. Simultaneously, the rotation of the lock core buckle 25 deforms the elastic member 23. The lock core buckle 25 in the locked position triggers the first switch 22, which sends a signal to the monitoring assembly, causing the telescopic member 26 to extend, driving the limit buckle 24 to rotate to the first position. The limit buckle 24 in the first position pushes against the lock core buckle 25, maintaining it in the locked position.

[0046] On the one hand, the lock shaft 12 holds the lock core buckle 25 in the locked position. On the other hand, the first switch 22 controls the telescopic member 26, rotating the limit buckle 24 to lock the lock core buckle 25 in the locked position, thus achieving double locking. Furthermore, in the absence of external force, the lock core buckle 25 always triggers the first switch 22, keeping the limit buckle 24 in the first position, locking the lock core buckle 25 and ensuring locking stability.

[0047] When the door is opened, the operating member is triggered, and the operating member feeds back a signal to the monitoring component to retract the telescopic member 26. The telescopic member 26 retracts and the limit buckle 24 is located in the second position. The limit buckle 24 is separated from the lock core buckle 25, and the locking shaft 12 is separated from the lock core buckle 25. The elastic member 23 is reset to make the lock core buckle 25 located in the unlocked position, and the lock core buckle 25 is separated from the first switch member 22.

[0048] During the specific operation, the operating member is triggered, the telescopic member 26 retracts and rotates the limit buckle 24 to the second position, so that the limit buckle 24 is separated from the lock core buckle 25. The control handle mechanism 1 is used to open the door, and the locking shaft 12 moves away from the lock core buckle 25, so that the locking shaft 12 and the lock core buckle 25 are separated. During the separation process, the locking shaft 12 drives the lock core buckle 25 to rotate. After the door opening action is completed, the lock core buckle 25 rotates to the unlocked position, and the locking shaft 12 and the lock core buckle 25 are separated. In the absence of the locking shaft 12, the elastic member 23 resets and rotates the lock core buckle 25 to the unlocked position. The lock core buckle 25 in the unlocked position is separated from the first switch member 22. By first operating the operating member to separate the limit buckle 24 from the lock core buckle 25, the force applied to open the door is reduced, facilitating subsequent door opening operations. The limit buckle 24 in the second position is separated from the lock core buckle 25, and both the lock core buckle 25 and the limit buckle 24 are in a free state. When closing the door again, it is only necessary to overcome the elastic force of the elastic member 23 to engage the locking shaft 12 with the lock core buckle 25. The user can unlock and lock the door 5 more conveniently and quickly, that is, conveniently and quickly open and close the door 5, thereby enhancing the user experience. The simplified operating process ensures that any operator can easily understand and use it correctly, reducing the risk of misoperation.

[0049] The lock core buckle 25 is further provided with a limiting groove 254 , and the locking shaft 12 is engaged in the limiting groove 254 .

[0050] The door lock system also includes a display screen, and the lock core mechanism 2 also includes a second switch 27 mounted on a mounting bracket 21. Both the display screen and the second switch 27 are electrically connected to the monitoring assembly. When the lock core latch 25 triggers the first switch 22 and the limit latch 24 triggers the second switch 27, the display screen indicates the locked state. When the lock core latch 25 triggers the first switch 22 and the limit latch 24 separates from the second switch 27, the display screen indicates the unlocked state. When the lock core latch 25 separates from the first switch 22 and the limit latch 24 separates from the second switch 27, the display screen indicates the open state. The display screen provides feedback, ensuring that the operator is aware of the door lock status at all times, enhancing operational safety. Exemplarily, the operating element is an operating button on the display screen.

[0051] The telescopic member 26 is a retaining electromagnet. Its pull rod 261 is connected to the limit buckle 24. The lock core buckle 25 triggers the first switch 22. The pull rod 261 extends, positioning the limit buckle 24 in the first position. When the operating member is triggered, the pull rod 261 retracts, positioning the limit buckle 24 in the second position. This retaining electromagnet offers the advantages of energy conservation, stable operation, and a long service life. When the first switch 22 is triggered, it sends a signal to the monitoring assembly, which energizes the retaining electromagnet in the forward direction, controlling the extension of the pull rod 261. When the operating member is triggered, the monitoring assembly energizes the retaining electromagnet in the reverse direction, controlling the retraction of the pull rod 261. For details, please refer to the working principle and usage of the retaining electromagnet, which will not be repeated here.

[0052] The door lock system also includes an alarm, which is electrically connected to the monitoring component and is used to prompt the status of the door lock system.

[0053] The first switch element 22 and the second switch element 27 are both micro switches. The micro switches have contacts 221 . The lock core buckle 25 and the limit buckle 24 are both provided with rods 251 . The rods 251 are used to trigger the contacts 221 .

[0054] Exemplarily, the elastic member 23 is a tension spring, and two ends of the tension spring are respectively connected to the rod portion 251 of the lock core buckle 25 and the mounting bracket 11 .

[0055] The mounting frame 11 is provided with a limiting ball plunger 29, and the lock core buckle 25 is provided with a limiting hole 253. When the locking shaft 12 is connected to the lock core buckle 25, the limiting ball plunger 29 passes through the limiting hole 253 to abut against one end of the locking shaft 12, further ensuring the stability of the locking state of the lock core buckle 25 and the locking shaft 12.

[0056] A first protective cover 13 is provided on the mounting frame 11, while a second protective cover 28 is provided on the fixing frame 21. The first switch member 22, elastic member 23, limit buckle 24, lock core buckle 25, and telescopic member 26 are disposed within the second protective cover 28. The second protective cover 28 defines an opening 281 through which the locking shaft 12 can pass to engage with the lock core buckle 25. The first and second protective covers 13 and 28 both protect components and enhance aesthetics. When locked, the outer surfaces of the first and second protective covers 13 and 28 are flush, further enhancing the aesthetics.

[0057] Monitoring components include electronic components such as circuit boards, which are prone to malfunction due to factors such as moisture and electromagnetic interference, resulting in malfunction. Figures 9-12As shown, the door lock system also includes a push rod 3, which is used to move the limit catch 24 to the second position. During operation, the push rod 3 moves the limit catch 24 to the second position, forcing the telescopic member 26 to retract. The handle mechanism 1 is then controlled to open the door, disengaging the locking shaft 12 from the lock core catch 25 and separating them. By providing an emergency unlocking mechanism, namely, an external push rod 3, manual unlocking is possible even in extreme situations such as power outages.

[0058] The push rod 3 is detachably connected to the side of the second protective cover 28, ensuring easy access to the emergency release mechanism. Specifically, the second protective cover 28 has a socket 282 through which the push rod 3 can pass to facilitate the activation of the limit buckle 24. For example, a slot 283 is provided on the side of the second protective cover 28 facing the ground, into which the push rod 3 is engaged.

[0059] Specifically, the fixing frame 21 also includes a base 211 and a mounting base 212, which are detachably connected. The mounting base 212 is installed between the base 211 and the second protective cover 28. The first switch 22, the limit buckle 24, the lock core buckle 25, the second protective cover 28 and the second switch 27 are all installed on the mounting base 212.

[0060] The mounting bracket 11, locking shaft 12, and first protective cover 13 are all connected by screws, nuts, and other fasteners, and their details are not repeated here. The fixing bracket 21, first switch member 22, limit buckle 24, lock core buckle 25, second protective cover 28, and second switch member 27 are all connected by screws, nuts, and other fasteners, and their details are not repeated here.

[0061] In existing dryer door lock systems, materials and designs are often not robust enough, making them susceptible to wear and damage from frequent use, shortening their service life. To address this issue, this embodiment utilizes high-quality, wear-resistant materials such as steel or aluminum to manufacture components, enhancing impact and torsional strength and ensuring the durability of the door lock system. Furthermore, it incorporates highly reliable monitoring components and a circuit board designed to be resistant to electromagnetic interference and moisture, reducing failure rates and lowering maintenance requirements and costs.

[0062] Optionally, the door lock system and dryer can share a display and monitoring component, such as a single-chip microcontroller. An interlock function can be implemented to prevent the dryer's main power source from being connected when the door is unlocked. An emergency unlock mechanism and interlock function ensure user safety in extreme situations.

[0063] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
