[0043] As long as possible, the various aspects and features described and illustrated in the specification can be applied alone, and these individual aspects can be the subject of a divisional application.
[0044] Referring to Figures 1-8 , an embodiment of the pull-out type washing equipment proposed by the present application, a pull-out type washing equipment 100 comprises: a shell 10, an inner box body 20 and a locking device 30, the inner box body 20 is pullable in the shell 10, the locking device 30 is arranged between the side plate 11 of the shell 10 and the side wall 21 of the inner box body 20, and the locking device 30 is used for realizing the locking of the inner box body 20. The locking device 30 has a lock column 31 arranged on one of the shell 10 and the inner box body 20, and a lock claw 32 arranged on the other one of the shell 10 and the inner box body 20, the lock claw 32 is matched with the lock column 31, and the locking device 30 further has a driving device 33 for driving the lock claw 32 to move to realize locking and unlocking.
[0045] In the embodiment, the pawl 32 is rotatably arranged and matched with the locking post 31 to effectively realize the locking of the inner box 20, reduce the occurrence of the situation of not being tightly closed and locked, improve the stability of the equipment during operation, avoid the inner box 20 from being shaken out of the shell, and thus ensure the normal work of the pull-out type washing equipment; and the gap between the shell 10 and the inner box 20 after being locked is reduced, and the shaking degree of the equipment during operation is reduced. The locking device 30 is arranged between the side plate 11 of the shell 10 and the side wall 21 of the inner box 20, has a large space in the front-rear direction, is convenient for structural arrangement, is beneficial to ensuring the structural strength and the locking firmness of the locking device, effectively locks and fixes the relatively heavy inner box 20, ensures the safety and stability of the equipment during operation, and improves the overall performance of the equipment.
[0046] In some embodiments of the present application, the pawl 32 is rotatably arranged, the driving device 33 has an output shaft 331, a connecting shaft 321 is arranged between the pawl 32 and the output shaft 331, and the connecting shaft 321 is fixedly arranged with the pawl 32. The pawl 32 is rotatably arranged, so that the output shaft 331 of the driving device 33 can more flexibly drive the pawl 32 to rotate through the connecting shaft 321. The connecting shaft 321 is fixedly arranged with the pawl 32, can accurately transmit the power of the output shaft of the driving device 33 to the pawl 32, ensures the rotation of the pawl 32 according to the predetermined angle and direction, and thus realizes the precise locking and unlocking actions. When the driving device 33 works, the rotation of the output shaft 331 is transmitted to the pawl 32 through the connecting shaft 321, so that the pawl 32 can reliably cooperate with or separate from the locking post 31, and the reliability and stability of the work of the locking device are improved. The rotatable pawl 32 and the structure connected with the driving device 33 through the connecting shaft 321 can adapt to a certain degree of position deviation or angle change of the inner box 20 during the pulling process. Even if there is some slight inaccuracy during the pulling of the inner box 20, the pawl 32 can still accurately cooperate with the locking post 31 through rotation, ensures the normal work of the locking device 30, and enhances the adaptability of the equipment to the actual use.
[0047] In some embodiments of the present application, the pawl 32 is located on the inner side of the side plate 11, and the driving device 33 is located on the outer side of the side plate 11. A connecting hole is formed on the side plate 11 for the connecting shaft 321 to pass through. The pawl 32, as a key component directly involved in the locking and unlocking actions, is located on the inner side of the side plate 11, which can be better protected. The driving device 33 is located on the outer side of the side plate 11, so that when the driving device needs to be checked, repaired or replaced due to equipment failure, it is not necessary to disassemble too many internal components, and the operation is more convenient and fast. The space on both sides of the side plate 11 can be fully utilized, and the pawl 32 and the driving device 33 are arranged on different sides to avoid conflict in space. For the limited internal space of the pull-out type washing device, this design helps to optimize the overall structural layout, making the installation of each component more compact and reasonable. The pawl 32 is located on the inner side of the side plate 11, reducing the possibility of accidental touching of the pawl by users or other personnel, which can cause the pawl to malfunction, and improving the safety of the device in use. By forming a connecting hole on the side plate 11 for the connecting shaft 321 to pass through, power transmission between the pawl 32 and the driving device 33 is achieved. This connection method is relatively simple and direct. The connecting shaft 321 can pass through the connecting hole more smoothly, transmitting the power of the driving device 33 to the pawl 32, and at the same time, the connecting hole can also support and position the connecting shaft to some extent, ensuring the stability and accuracy of power transmission.
[0048] In some embodiments of the present application, a shaft sleeve 34 is sleeved on the outer side of the connecting shaft 321, and the shaft sleeve 34 is located in the connecting hole. The shaft sleeve 34 can form a buffer layer between the connecting shaft 321 and the connecting hole of the side plate 11. When the driving device 33 drives the connecting shaft 321 to rotate and in turn drives the pawl 32 to act, relative movement will occur between the connecting shaft 321 and the connecting hole. The presence of the shaft sleeve 34 can avoid direct friction between the connecting shaft and the hole wall of the connecting hole, thereby reducing wear and tear between the two, prolonging the service life of the connecting shaft and the side plate, and ensuring long-term stable operation of the locking device. The shaft sleeve 34 can fill the gap between the connecting shaft 321 and the connecting hole, and play a certain sealing role. The shaft sleeve 34 can better position and support the connecting shaft 321, so that the connecting shaft 321 remains in a more stable state during rotation. This helps to ensure that the pawl 32 can rotate accurately according to the predetermined angle and direction, improves the accuracy of the cooperation between the pawl 32 and the lock cylinder 31, and thus improves the locking and unlocking effect of the locking device and enhances the reliability of the equipment.
[0049] In some embodiments of the present application, a mounting groove 322 matching the output shaft 331 is formed on one end of the connecting shaft 321 close to the output shaft 331, and the output shaft 331 is located in the mounting groove 322. A torque-transferring pin key structure is arranged between the mounting groove 322 and the output shaft 331, and the pin key structure is a pin groove formed on the output shaft 331 and a pin protrusion extending radially inward along the mounting groove 322, which is located in the pin groove. By forming a mounting groove matching the output shaft on one end of the connecting shaft 321 close to the output shaft, and arranging a pin key structure (pin groove and pin protrusion cooperate), the output shaft of the driving device 33 can effectively transmit torque to the connecting shaft. The pin protrusion is located in the pin groove, so that a stable connection is formed between them. When the output shaft rotates, it can drive the connecting shaft to rotate synchronously, thereby driving the locking pawl to perform locking or unlocking action, ensuring the reliability and stability of the locking device in operation. The existence of the pin key structure effectively limits the relative rotation between the output shaft and the connecting shaft. The cooperation of the mounting groove and the pin key structure enhances the connection strength between the connecting shaft and the output shaft. The design of the mounting groove matching the output shaft and the positioning effect of the pin key structure help to ensure the installation accuracy of the output shaft and the connecting shaft.
[0050] In some embodiments of the present application, the locking pawl 32 is an eccentric wheel structure, and the locking pawl 32 has a lobe 320 extending away from the rotation axis. In the locked state of the locking device 30, the lobe 320 is located on the upper side or lower side of the rotation axis, and the lobe 320 is blocked at the rear side of the lock post 31. The locking pawl 32 adopts an eccentric wheel structure, and its contact and cooperation with the lock post 31 during rotation are more stable and reliable. When the lobe 320 is located on the upper side or lower side of the rotation axis and is blocked at the rear side of the lock post 31, an effective block can be formed to limit the movement of the lock post 31, thereby firmly locking the inner box 20 and preventing it from being pulled out due to vibration during equipment operation. Compared with ordinary structures, the lobe of the eccentric wheel structure can provide greater locking force, improving the reliability of the locking device. The lobe of the eccentric wheel structure can achieve a larger rotation angle change in a limited space, thereby more effectively utilizing the space between the shell side plate and the inner box side wall. This locking mode in which the lobe 32 is blocked at the rear side of the lock post 31 is relatively stable in contact between the lobe 31 and the lock post 31 under normal working conditions, reducing unnecessary friction and collision. When unlocking is needed, the driving device 33 drives the lobe 32 to rotate. Due to the characteristics of the eccentric wheel structure, only a small driving force is needed to make the lobe 320 escape from the blocking position of the lock post, achieving the unlocking action. In actual use, the inner box 20 may have certain installation errors or slight positional deviations during pulling. The lobe 32 of the eccentric wheel structure can adapt to these errors and deviations to a certain extent. As long as the lobe 320 can be blocked at the rear side of the lock post, effective locking can be achieved, enhancing the adaptability of the locking device to actual working conditions and improving the stability and reliability of the equipment.
[0051] In some embodiments of the present application, the lock post 31 is located above or below the horizontal plane of the rotation axis of the lock claw 32; in the unlocked state of the locking device 30, the protruding claw 320 is in the horizontal direction of the rotation axis; at this time, the lock post 31 can be moved forward and backward with the inner box body 20. In the unlocked state, the protruding claw 320 is in the horizontal direction of the rotation axis, at this time, it will not block the lock post 31, so that the lock post 31 can be freely moved forward and backward with the inner box body 20. The lock post 31 is located above or below the horizontal plane of the rotation axis of the lock claw 32, which makes full use of the space, so that the installation of the locking device between the shell side plate 11 and the inner box body side wall 21 is more reasonable and compact. When it is necessary to lock the inner box body 20, the driving device 33 drives the lock claw 32 to rotate, so that the protruding claw 320 moves to the upper or lower side of the rotation axis and is blocked at the rear side of the lock post 31, thereby achieving firm locking; and when unlocking, the protruding claw 320 returns to the horizontal direction, and the restriction on the lock post 31 is removed. This clear state switching mechanism improves the stability and reliability of the locking device operation, and reduces the possibility of misoperation.
[0052] In some embodiments of the present application, the lock post 31 extends outward on the side wall 21, and the lock claw 32 extends inward on the side plate 11; in the locked state of the locking device 30, the lock claw 32 is blocked at the front side of the lock post 31. The driving device 33 is a stepping motor. The lock post 31 extends outward on the side wall 21, and the lock claw 32 extends inward on the side plate 11, which can make full use of the space between the shell side plate and the inner box body side wall, and make the structure of the locking device more compact. In the locked state, the lock claw 32 is blocked at the front side of the lock post 31, forming an effective blocking structure. The driving device 33 adopts a stepping motor, which has precise stepping control characteristics. It can accurately control the rotation angle and position of the lock claw 32 according to the preset instructions, so as to realize accurate locking and unlocking operation. Whether it is to make the lock claw 32 accurately block at the front side of the lock post 31 when locking, or to make the lock claw 32 return to the appropriate position when unlocking, the stepping motor can ensure the accuracy of the action, and improve the working precision of the locking device.
[0053] In some other embodiments of the present application, a lock slot matching the lock post 31 is formed on the lock jaw 32; in the locked state of the locking device 30, the lock post 31 is located in the lock slot. The lock slot is an arc-shaped slot with the rotation axis of the lock jaw 32 as the center. The arc-shaped lock slot with the rotation axis of the lock jaw 32 as the center makes the position of the lock post 31 in the lock slot relatively fixed, no matter what direction the external force (such as the force generated by vibration) the inner box body is subjected to, the lock post 31 can be better limited in the lock slot, reducing the possibility of the lock post coming out, thereby greatly improving the stability and reliability of the locking. The lock jaw 32 is rotatably arranged, and the design of the arc-shaped lock slot is consistent with the rotation movement of the lock jaw 32. When the driving device 33 drives the lock jaw 32 to rotate, the lock post 31 can smoothly move in the arc-shaped lock slot along with the rotation of the lock jaw 32, ensuring the smoothness of the locking and unlocking process.
[0054] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalent ones; and these modifications or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions claimed by the present application.
