[0039] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] The following is for reference. Figures 1-9 A door lock assembly 100 according to an embodiment of the present invention is described.

[0041] like Figure 2 and Figure 3 As shown, the door lock assembly 100 according to an embodiment of this application includes: a latch 10, a door bolt 20, and an unlocking component 30.

[0042] The latch 10 is disposed on the door body 200; the latch 20 is movably disposed on the housing 300 to switch between an unlocked position and a locked position; the door body 200 is closable disposed on the housing 300; the unlocking element 30 is disposed on the side of the housing 300 and is linked with the latch 20, and is adapted to trigger the latch 20 to switch the latch 20 from the locked position to the unlocked position.

[0043] like Figure 1 As shown, specifically, the cabinet 300 has a cooking space, and the door 200 is closable in the front-to-back direction to open or close the cooking space. A latch 20 is provided on the cabinet 300, and a latch 10 is provided on the side wall of the door 200. The latch 20 and the latch 10 are correspondingly provided. The latch 20 can move in the up-down direction. When it is necessary to close the door 200, force is applied to push the door 200, and the latch 10 moves toward the latch 20. After the latch 10 touches the latch 20, it pushes the latch 20 up or down. The latch 20 moves up or down to the unlocked position. When the latch 10 extends into the cabinet 300, the latch 20 moves down or up to its original position. The latch 20 and the latch 10 cooperate. At this time, the latch 20 is in the locked position, and the latch 20 stops the latch 10 to prevent the latch 10 from moving forward. At this time, if an external force is directly applied to pull the door 200, the door 200 cannot be opened.

[0044] It should be noted that the unlocking piece 30 is also arranged on the box body 300, and for the purpose of aesthetics, convenient control and increasing the difficulty of triggering by children, the unlocking piece 30 can be arranged on the side surface of the box body 300, and the unlocking piece 30 is arranged close to the door latch 20 to facilitate the linkage between the unlocking piece 30 and the door latch 20. For example, the unlocking piece 30 can be arranged above or below the door latch 20 (corresponding to the unlocking direction of the door latch 20, upward unlocking is located below, and downward unlocking is located above). That is, when the unlocking piece 30 is arranged below the door latch 20, if the door body 200 needs to be opened, the unlocking piece 30 needs to be controlled first, the unlocking piece 30 is linked with the door latch 20, the door latch 20 is controlled to move upward, the door latch 20 no longer stops the lock catch 10 when moving to the unlocking position, the lock catch 10 is unlocked with the door latch 20, and then an external force is applied to pull the door body 200, so that the door body 200 can be opened. When the unlocking piece 30 is arranged above the door latch 20, if the door body 200 needs to be opened, the unlocking piece 30 needs to be controlled first, the unlocking piece 30 is linked with the door latch 20, the door latch 20 is controlled to move downward, the door latch 20 no longer stops the lock catch 10 when moving to the unlocking position, the lock catch 10 is unlocked with the door latch 20, and then an external force is applied to pull the door body 200, so that the door body 200 can be opened.

[0045] According to the door lock assembly 100 of the embodiments of the present application, the locking step of the door body 200 is added, the door body 200 is locked with the box body 300, the door body 200 cannot be directly opened, and the door body 200 can be opened only after being unlocked. The door body 200 is opened in the front-back direction, and the unlocking of the door body 200 needs to be triggered in the up-down direction. Therefore, the door body 200 is not easy to be opened by children, the difficulty of opening the door body 200 by children is increased, the safety of children is protected, the situation that children are scalded by mistake of opening the door body 200 is avoided, and the use safety is improved. The structure of the door lock assembly 100 is simple, the operation is convenient, the unlocking piece 30 does not affect the overall appearance structure, and the aesthetics is ensured.

[0046] It should be noted that by arranging the unlocking piece 30, a pre-step of directly opening the door body 200 to realize the opening of the cooking space is arranged, that is, the step of unlocking the door latch 20 by the unlocking piece 30 is arranged to increase the unlocking difficulty and avoid that the door body 200 is opened by children by directly pulling the door body 200, thereby improving the safety.

[0047] As shown in Figure 4 According to some embodiments of the present application, the unlocking piece 30 includes a trigger button 31 and a delay release piece 32. The trigger button 31 is arranged on the box body 300 in a pressable manner, and the trigger button 31 is used to push the delay release piece 32 to move to push the door latch 20 to move from the locking position to the unlocking position. The delay release piece 32 is suitable for delaying the reset of the trigger button 31.

[0048] Specifically, the trigger button 31 is located on the side of the housing 300, opposite to the latch 20. The delayed release member 32 is connected to the trigger button 31 and is located between the trigger button 31 and the latch 20. Pressing the trigger button 31 can push the delayed release member 32 to move. The movement of the delayed release member 32 can push the latch 20 to the unlock position, thereby unlocking the latch 20 from the latch 10.

[0049] For example, when the trigger button 31 is located on the lower side of the housing 300, pressing the trigger button 31 upwards will push the delayed release member 32 upwards, which in turn will push the latch 20 upwards, moving the latch 20 from the locked position to the unlocked position, thus unlocking the latch 20 from the latch 10. When the trigger button 31 is located on the upper side of the housing 300, pressing the trigger button 31 downwards will push the delayed release member 32 downwards, which in turn will push the latch 20 downwards, moving the latch 20 from the locked position to the unlocked position, thus unlocking the latch 20 from the latch 10.

[0050] In addition, the delayed release member 32 can cause the trigger button 31 to be reset after a delay. For example, the delayed release member 32 can cause the trigger button 31 to be reset to its original position after 15 seconds. During the delayed reset of the trigger button 31, the latch 20 can be synchronously driven to reset to the locked position by the delayed release member 32. The corresponding latch 20 can also be synchronously reset to the locked position under its own gravity.

[0051] With this design, the structure of the unlocking component 30 is simpler and easier to control, making it easier to link with the door latch 20, thereby controlling the unlocking of the door latch 20 and the latch 10, thus improving convenience.

[0052] like Figure 4 As shown, in some embodiments, the delayed release member 32 includes: a delayed housing 321, a delayed rod 322, a piston 323, and a reset member 324. The delayed housing 321 defines a receiving cavity filled with damping oil. The delayed rod 322 passes through the receiving cavity, with one end connected to the trigger button 31 and the other end used to push the latch 20. The reset member 324 is sleeved on the delayed rod 322, with one end pushing against the receiving cavity and the other end pushing against the piston 323 to drive the piston 323 to move. The piston 323 is slidably disposed in the receiving cavity and fixed to the delayed rod 322 to drive the delayed rod 322 to reset after a delay.

[0053] Specifically, the delay housing 321, the end cover and the oil seal and the like define a containing cavity, the delay rod 322, the piston 323 and the reset member 324 are arranged in the containing cavity, the delay rod 322 is located on the center line of the containing cavity in the up-down direction, the piston 323 is fixed on the outer periphery of the delay rod 322, and a sealing ring is further sleeved on the piston 323 to separate the containing cavity into an inner cavity and an outer cavity, the reset member 324 and the piston 323 are located in the inner cavity, and the inner cavity and the outer cavity are filled with damping oil.

[0054] It should be noted that when the trigger button 31 is pressed, the delay rod 322 connected with the trigger button 31 is pushed, the delay rod 322 pushes the door latch 20 to move, at the same time the delay rod 322 is pushed, the reset member 324 is compressed, the reset member 324 drives the piston 323 to move, and after the unlocking is completed, the trigger button 31 is released, the reset member 324 overcomes the damping oil resistance assembly to restore to the original length, and it drives the piston 323 to gradually reset, the piston 323 is fixed with the delay rod 322, so as to drive the delay rod 322 to realize the delay reset. In this way, the structure and principle are simpler, the operation and control are facilitated, the delay reset of the delay rod 322 can be realized, and the door latch 20 can be automatically reset to the locking position.

[0055] As shown in Figure 4 , specifically, the delay housing 321 is provided with a recessed avoiding groove 3211, and at least part of the trigger button 31 is located in the avoiding groove 3211.

[0056] When the trigger button 31 is arranged on the upper side of the box body 300, the upper end of the delay housing 321 is provided with a downward recessed avoiding groove 3211; when the trigger button 31 is arranged on the lower side of the box body 300, the lower end of the delay housing 321 is provided with an upward recessed avoiding groove 3211. When the trigger button 31 is pressed, the trigger button 31 moves towards the avoiding groove 3211, and at least part of the trigger button 31 enters the avoiding groove 3211. In this way, the structure is simple, the trigger button 31 can enter the avoiding groove 3211, the space layout is more reasonable, the space utilization is improved, and the trigger stability and movement stability of the trigger button 31 can be improved through the sliding cooperation between the trigger button 31 and the avoiding groove 3211.

[0057] As shown in Figure 5 , further, the door latch 20 comprises a door latch bracket 21 and a door latch rod 22, the door latch rod 22 is slidably arranged on the door latch bracket 21 to switch between the unlocking position and the locking position, and the door latch bracket 21 is connected with the box body 300.

[0058] Specifically, the door latch support 21 is fixed vertically on the cabinet 300 by fasteners, the door latch rod 22 is arranged vertically on the door latch support 21, and the door latch rod 22 is movable up and down along the door latch support 21. If the unlocking member 30 is installed above the door latch support 21, the trigger button 31 is pressed, the unlocking member 30 pushes the door latch rod 22 to move downward to the unlocking position, the trigger button 31 is released, and the door latch 20 is automatically reset to the locking position. If the unlocking member 30 is installed below the door latch support 21, the trigger button 31 is pressed, the unlocking member 30 pushes the door latch rod 22 to move upward to the unlocking position, the trigger button 31 is released, and the door latch 20 is automatically reset to the locking position. In this way, the structure of the door latch 20 is simpler, and the door latch rod 22 can be moved up and down, thereby achieving the locking or unlocking of the door body 200 and the cabinet 300.

[0059] As shown in Figure 8 and Figure 9 In some embodiments, the door latch rod 22 includes a connecting rod 221 and a pushing rod 222 and a locking rod 223 at both ends of the connecting rod 221. The pushing rod 222 is bent relative to the connecting rod 221 and is connected to the delay rod 322. The locking rod 223 is bent relative to the connecting rod 221 and is selectively locked with the lock catch 10.

[0060] It should be noted that the connecting rod 221 is a vertical long rod, the pushing rod 222 is arranged vertically relative to the connecting rod 221, the pushing rod 222 is arranged adjacent to the unlocking member 30, one end of the pushing rod 222 is connected to one end of the connecting rod 221 close to the unlocking member 30, and the other end is bent forward or backward. The locking rod 223 is also arranged vertically relative to the connecting rod 221, one end of the pushing rod 222 is connected to the other end of the connecting rod 221, and the other end of the pushing rod 222 can be bent leftward or rightward. If the unlocking member 30 is arranged on the upper side of the cabinet 300, the pushing rod 222 is located at the upper end of the connecting rod 221, and the locking rod 223 is located at the lower end of the connecting rod 221. If the unlocking member 30 is arranged on the lower side of the cabinet 300, the pushing rod 222 is located at the lower end of the connecting rod 221, and the locking rod 223 is located at the upper end of the connecting rod 221.

[0061] In this way, the structure of the door latch rod 22 is simpler, the pushing rod 222 is connected to the unlocking member 30, and the locking rod 223 is connected to the lock catch 10, which is easier to operate and improves the convenience.

[0062] As shown in Figure 4 Specifically, the unlocking member 30 further includes a push plate 33 fixed on the delay rod 322 and adapted to push the pushing rod 222.

[0063] The push plate 33 is located between the push rod 222 and the delay release 32, one end of the delay rod 322 is fixed with the trigger button 31, and the other end is fixed with the push plate 33. When the trigger button 31 is pressed, the delay rod 322 is pushed, which drives the push plate 33 to move upward or downward. The push plate 33 is linked with the push rod 222, and the door latch 20 moves upward or downward. In this way, the structure is simpler, the unlocking part 30 can push the door latch 20 to move, and the trigger stability is improved.

[0064] As shown in Figure 5 Further, a plurality of limiting blocks 211 are arranged on the door latch bracket 21, and a sliding space is defined between the plurality of limiting blocks 211. The connecting rod 221 is arranged in the sliding space.

[0065] Specifically, a plurality of limiting blocks 211 are arranged on the door latch bracket 21 at intervals, and the plurality of limiting blocks 211 define a sliding space of the connecting rod 221. The connecting rod 221 can slide up and down in the sliding space, avoiding the connecting rod 211 from moving during the sliding process. The sliding direction of the connecting rod 221 can be limited, avoiding the sliding direction of the connecting rod 221 from deviating, improving the trigger accuracy, and enabling accurate locking or unlocking.

[0066] As shown in Figures 5-9 In some embodiments, one end of the lock catch 10 is connected with the door body 200, and a hook portion 11 is arranged on the free end of the lock catch 10 to selectively lock with the door latch 20.

[0067] It should be noted that one end of the lock catch 10 is connected with the door body 200, and the other end extends towards the cabinet 300. This end is the free end of the lock catch 10, and a hook portion 11 is arranged on this end. When it is necessary to close the door body 200, the door body 200 is pushed, and the hook portion 11 moves towards the door latch 20. After the hook portion 11 touches the door latch 20, the door latch 20 is pushed to move upward or downward to the unlocking position. After the hook portion 11 extends into the cabinet 300, the door latch 20 moves downward or upward to the original position, and the door latch 20 is locked with the hook portion 11. When it is necessary to open the door body 200, the unlocking part 30 is pressed, which controls the door latch 20 to move upward or downward. When the door latch 20 moves to the unlocking position, the hook portion 11 is no longer stopped, and the hook portion 11 is unlocked with the door latch 20. In this way, the structure is simpler, and the multiple hook portions 11 are locked to make the door body 200 and the cabinet 300 more tightly closed.
