[0042] As long as possible, the various aspects and features described and illustrated in the specification can be applied individually, and these individual aspects can be the subject of a divisional application.

[0043] Referring to Figures 1-6 It is an embodiment of the drawer type washing equipment provided by the present application, a drawer type washing equipment 100 comprising: a shell 10, a drawer 20 and a door lock device 30, the drawer 20 is pullable in the shell 10, the door lock device 30 is used for realizing the locking of the drawer 20. The door lock device 30 has a plurality of movable setting lock rods 31, a rotating disc 32 for pushing the plurality of lock rods 31 to move, a plurality of driving grooves 321 matched with the lock rods 31 are opened on the rotating disc 32, the lock rod is provided with a driving convex located in the driving groove, and the driving convex is movably located in the driving groove 321.

[0044] In the embodiment, the rotatable turntable 32 and the movable plurality of locking rods 31 are arranged, when the drawer 20 is instantaneously moved to generate an impact, the plurality of locking rods 31 can jointly bear the impact force, compared with the case that a single locking rod bears all the impact in the prior art, the stress can be effectively dispersed, the problem of fracture failure of the single locking rod due to stress concentration is avoided, thereby the service life and reliability of the locking rod are improved, and the situation that the drawer is detached from the containing box is reduced. The plurality of locking rods 31 act simultaneously, the drawer 20 can be locked from multiple directions, compared with the locking mode of the single locking rod, more stable locking effect can be provided, the drawer 20 is more stably kept in the shell during the working process of the washing equipment, and troubles caused by shaking or detachment of the drawer are reduced. The design that the driving protrusion is movable in the driving groove enables the position and state of the locking rod 31 to be adjusted according to actual conditions, for drawers of different sizes or specifications, by reasonably setting the related parameters of the turntable and the locking rod, the use requirement of the drawer can be better adapted, and the versatility and adaptability of the door lock device are improved.

[0045] In the embodiment, the two locking rods 31 arranged left and right are arranged, in other embodiments, the locking rods arranged in the up-down direction or the locking rods arranged in the left-right direction and the up-down direction can also be arranged.

[0046] In some embodiments of the application, the door lock device 30 further includes a mounting seat 33, the mounting seat 33 is provided with a containing cavity for containing the turntable 32, and the mounting seat 33 is provided with a limiting groove 331 for limiting the moving direction of the locking rod 31, so that when the turntable 32 rotates, the locking rod 31 can only move linearly in the direction limited by the limiting groove 331; the turntable 32 has a rotating shaft 322, and the locking rod 31 passes through the limiting groove 331. The arrangement of the limiting groove 331 enables the locking rod 31 to move linearly in the direction limited by the limiting groove 331 when the turntable 32 rotates; the deviation or shaking of the locking rod 31 during movement can be avoided, and the accuracy and stability of the movement of the locking rod 31 are ensured. When the drawer 20 is impacted by external force, the locking rod 31 can more reliably bear the impact force, maintain the locking state, and reduce the possibility of locking failure caused by shaking of the locking rod. The turntable 32 is contained by the mounting seat 33, and the movement of the locking rod 31 is constrained by the limiting groove 331, so that the structure of the entire door lock device is more compact and reasonable; the acting force can be better dispersed and transmitted, the abrasion and looseness between components are reduced, and the overall reliability and service life of the door lock device are improved.

[0047] In some embodiments of the present application, the mounting base 33 has a first seat body 335 and a second seat body 336 arranged oppositely, the first seat body 335 is provided with an inner recessed accommodating cavity, and the second seat body 336 is provided with an inner recessed limiting groove 331. The accommodating cavity and the limiting groove 331 are arranged on different seat bodies respectively, which can significantly reduce the complexity of machining compared to machining two different types of structures with different functions on one integral structure at the same time; the accommodating cavity is usually a relatively regular cavity structure for accommodating the rotating disc 32, while the limiting groove 331 needs to accurately control the moving direction of the lock rod 31, and separate machining can use more suitable machining processes and equipment according to the respective characteristics, thereby improving the machining precision and efficiency. If the door lock device 30 fails during use, for example, the rotating disc 32 is damaged or the lock rod 31 is worn out, since the first seat body 335 and the second seat body 336 are relatively independent structures, they can be easily disassembled, and the damaged parts can be repaired or replaced individually. The oppositely arranged first seat body 335 and the second seat body 336 can be tightly combined together through a reasonable connecting method (such as bolt connection, buckle connection, etc.), forming a stable whole. The separately arranged accommodating cavity and limiting groove 331 can more reasonably utilize the space of the mounting base 33, avoiding mutual interference between the parts due to too compact structure. The accommodating cavity provides sufficient rotating space for the rotating disc 32, while the limiting groove 331 provides an independent channel for the linear movement of the lock rod 31, so that the parts of the door lock device 30 can work smoothly in cooperation.

[0048] In some embodiments of the present application, the limiting groove 331 is arranged along the radial direction of the rotating disc 32. The limiting groove 331 extending along the radial direction of the rotating disc 32 provides a precise linear motion guide for the lock rod 31. When the rotating disc 32 rotates, the lock rod 31 can strictly move linearly along the radial direction under the constraint of the limiting groove 331. This linear motion mode ensures the stability and accuracy of the lock rod 31 during the locking and unlocking process, so that the lock rod 31 can accurately reach the predetermined locking or unlocking position, thereby improving the working reliability of the door lock device. The driving groove 321 is an arc-shaped groove with gradually increasing size from the axis of the rotating disc. When the rotating disc 32 rotates, due to the special shape of the arc-shaped groove, the driving protrusion on the lock rod 31 moves in the driving groove 321, which drives the lock rod 31 to move linearly along the radial direction of the limiting groove 331. By controlling the rotation angle of the rotating disc 32, the extension and retraction length of the lock rod 31 can be accurately adjusted to adapt to the locking requirements of drawers of different sizes or specifications. During the rotation of the rotating disc 32, the cooperation between the driving groove 321 and the driving protrusion can efficiently convert the rotational motion of the rotating disc 32 into the linear motion of the lock rod 31. The design of the arc-shaped groove makes the force transmission smoother and more stable, reducing energy loss and mechanical wear. Due to the arc-shaped design of the driving groove 321, each lock rod 31 can be driven to move synchronously by the rotating disc 32, thereby locking the drawer 20 from multiple directions.

[0049] In some embodiments of the present application, the door lock device 30 further has a guide seat 34 for limiting the lock rod 31, and a guide groove for the lock rod 31 to pass through is formed in the guide seat 34. The guide seat 34 and the mounting seat 33 are arranged in a spaced manner. The limiting groove 331 on the mounting seat 33 preliminarily limits the moving direction of the lock rod 31, and the guide groove on the guide seat 34 further provides a guide for the lock rod 31; the double guide structure makes the lock rod 31 more stable during movement, which can effectively avoid the lock rod from shaking, deviating, etc. The guide groove can make the lock rod 31 move smoothly and reduce the jamming caused by friction or collision between the lock rod and other components. The guide seat 40 and the mounting seat 33 are arranged in a spaced manner, so that the lock rod 31 is supported and guided at different positions, and the stress borne by the lock rod 31 can be dispersed to two different components.

[0050] In some embodiments of the present application, two lock rods 31 are oppositely arranged, and the moving directions of the two lock rods 31 are opposite. The two oppositely arranged and opposite moving lock rods 31 can lock the drawer 20 from two different directions; so that the fixation of the drawer 20 in the shell 10 is more stable, compared with the locking mode of a single lock rod, it can effectively resist the external force of the drawer at various angles in the horizontal direction, reduce the risk of drawer shaking, displacement and even falling out. The door lock device 30 also has a motor 35 for driving the rotation of the rotating disc 31. By driving the rotating disc 32 to rotate through the motor 35, the movement of the two lock rods 31 is controlled, and the locking and unlocking of the drawer is realized; the user only needs to control the operation of the motor, so as to easily complete the locking and unlocking process of the drawer, greatly improving the convenience and efficiency of operation.

[0051] In some embodiments of the present application, the lock rod 31 has a lock rod body 311 arranged in parallel with the rotating disc 32, an extension 312 arranged in extension along the lock rod body 311, and a lock head 313 arranged in extension along the rear end of the extension 312 and away from the rotating disc 32. The lock rod body 311 is arranged in parallel with the rotating disc 32, so that the force transmitted to the lock rod through the driving groove 321 and the driving convex when the rotating disc 32 rotates can be more evenly distributed on the lock rod body. The extension 312 extends rearward along the lock rod body 311, further increasing the force transmission distance and buffer space, so that the force can be more smoothly transmitted from the lock rod body to the lock head 313. This structural design helps to reduce stress concentration and improve the mechanical properties of the entire lock rod, so that it can withstand greater impact force without being easily damaged. The lock rod body 311, the extension 312 and the lock head 313 form a relatively stable overall structure; the lock rod body provides basic support and guiding effect for the entire lock rod, the extension plays a transition and connection role, and the lock head is the key part to realize the locking function. The three cooperate with each other to make the lock rod more stable during movement. The lock head 313 is arranged in extension along the rear end of the extension 312 and away from the rotating disc 32. This design makes the lock head better cooperate with the locking position on the drawer or the shell. When the lock rod 31 is extended, the lock head 313 can be deeply inserted into the corresponding locking position to form a reliable locking structure, effectively preventing the drawer 20 from falling out of the shell 10. Moreover, the bent lock head 313 can increase the contact area with the locking position and improve the firmness of the locking.

[0052] In some embodiments of the present application, the lock head 313 is arranged in parallel with the lock rod body 311, and the extension direction of the lock head 313 is perpendicular to the pulling direction of the drawer 20. A lock hole matched with the lock head 313 is arranged on the shell 10, and the lock rod 31 is arranged on the drawer 20. When the lock rod 31 is extended to make the lock head 313 inserted into the lock hole on the shell 10, a blocking force perpendicular to the pulling direction of the drawer 20 can be formed. This perpendicular locking mode can greatly enhance the constraint effect on the drawer 20. The parallel arrangement of the lock head 313 and the lock rod body 311 makes the lock rod more smooth and stable when inserted into the lock hole. The parallel structure design can ensure the cooperation precision between the lock head 313 and the lock hole, reduce the shaking and gap, and make the connection between the lock rod and the shell more close and reliable. The lock head 313 is parallel to the lock rod body 311, and the extension direction of the lock head 313 is perpendicular to the pulling direction of the drawer 20. In the process of driving the lock rod 31 to move by the motor 35 to realize locking and unlocking, the movement track of the lock rod 31 is more definite and regular. This makes the lock head 313 accurately align with the lock hole, smoothly insert or exit, and the operation is more smooth, reducing the failure of locking or difficulty of unlocking caused by the position deviation of the lock rod, and improving the operation efficiency of the door lock device.

[0053] In some embodiments of the present application, the lock rod body 311 is arranged on the door body at the front of the drawer 20, and an extension hole for the lock head 313 to extend out is arranged on the side wall of the drawer 20. A lock hole matched with the lock head 313 is arranged on the inner side of the side plate of the shell 10. Arranging the lock rod body 311 on the door body at the front of the drawer 20 is convenient for user operation. When the user opens or closes the drawer 20, it is easy to touch the related components of the door lock device 30. Whether it is manual control or driving the motor through the associated control button to make the lock rod act, the operation position is very convenient. The lock head 313 extends out from the extension hole of the side wall of the drawer 20 and is inserted into the lock hole on the inner side of the side plate of the shell 10, which is equivalent to adding a locking point on the side of the drawer 20. Compared with locking only at the front end of the drawer 20, this multi-directional locking mode can better resist external forces acting on the drawer in different directions, greatly enhancing the stability of the drawer 20 in the shell.

[0054] In some embodiments of the present application, the door lock device 30 also has a pull rope 36 that can realize manual reset of the rotating disc 32. The pull rope 36 is connected to the rotating disc 32. The existence of the pull rope 36 provides a manual operation mode. The user can rotate the rotating disc 32 by pulling the pull rope, and then drive the lock rod 31 to move to realize unlocking of the drawer, avoiding the situation that the drawer cannot be used due to power problems, and ensuring that the user can still normally operate the washing equipment in special circumstances.

[0055] The above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, for those skilled in the art, the technical solutions recorded in the foregoing examples can still be modified, or some of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions claimed by the present application.
