[0031] The existing detergent box not only requires manual operation during the opening or closing process, but also has the risk of slipping when the washing machine shakes.

[0032] Different from the prior art, embodiments of the present invention provide an improved detergent box assembly and a washing device including the same.

[0033] The detergent box assembly includes: a box body suitable for being pushed, a motion assembly suitable for driving the box body to pop out, and a lock assembly suitable for locking or unlocking the box body. The lock assembly includes a push rod, a motion diverter connected to the push rod for movement, and a lock pin connected to the motion diverter for movement. The push rod is suitable for moving with the box body when it is pushed in a first direction, and when moving, it pushes the motion diverter to rotate and drives the lock pin to move to lock or unlock the box body.

[0034] Compared with the prior art, in the technical solution provided in the embodiment of the present invention, the box body suitable for storing detergent can be closed and locked or unlocked and opened simply by being pushed, which is simple to operate and saves time and effort. Moreover, the box body is in a locked state when closed, which can prevent the risk of it slipping due to shaking.

[0035] To facilitate the description of the detergent box assembly and washing device provided by the embodiments of the present invention, six directions, namely front, rear, left, right, top, and bottom, are illustrated in some of the drawings provided by the embodiments of the present invention. These six directions are determined based on the perspective of the detergent box assembly and the washing device facing the user under normal use. Among them, "front" refers to the direction in which the detergent box assembly and the washing device face the user, "rear" represents the direction opposite to "front", and "left", "right", "top", and "bottom" are determined based on the natural orientation of the aforementioned "front" and "rear" directions. It should be understood that when observing from other perspectives of the detergent box assembly and the washing device, there will also be front, rear, left, right, top, and bottom directions corresponding to the corresponding perspectives. The front, rear, left, right, top, and bottom directions illustrated in some of the drawings provided by the embodiments of the present invention are merely for the convenience of describing the technical solutions of the embodiments of the present invention and do not constitute a restrictive interpretation of these technical solutions.

[0036] In order to make the purpose, features and beneficial effects of the embodiments of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] Reference Figure 1 The detergent box assembly 10 includes a box body 100 , a moving assembly 200 and a lock assembly 300 .

[0038] Specifically, the box body 100 is used to accommodate detergent and is suitable for being pushed to close and lock, or unlock and open. The lock assembly 300 is suitable for being directly or indirectly driven by the box body 100 to lock the box body 100 or unlock the box body 100 when the box body 100 is pushed. The motion assembly 200 is suitable for driving the box body 100 to pop out when the box body 100 is unlocked, thereby opening it.

[0039] In this embodiment of the present invention, the direction in which the box body 100 is pushed and the direction in which it is ejected are both related to the position of the box body 100 in space. For ease of explanation, in this embodiment of the present invention, the direction in which the box body 100 is pushed is collectively referred to as the first direction M1, and the direction in which the box body 100 is ejected is collectively referred to as the second direction M2. Correspondingly, two directions perpendicular to the first direction M1 and the second direction M2 can be referred to as the third direction M3 and the fourth direction M4, respectively.

[0040] In the instruction manual Figures 1 to 9 In the embodiment shown, the first direction M1 may be a "front" direction, the second direction M2 may be a "back" direction opposite to the first direction M1, the third direction M3 may be an "up" direction, and the fourth direction M4 may be a "down" direction opposite to the third direction M3. In the embodiment of the present invention, these directions are only for the convenience of description in the appended drawings. Figures 1 to 9 The technical solutions of the embodiments shown do not constitute a restrictive interpretation of these technical solutions.

[0041] Reference Figure 1 , the box body 100 can be pushed along a first direction M1 and popped up along a second direction M2 opposite to the first direction M1 to open.

[0042] In a specific implementation, the box body 100 has an opening 101 that opens upwards so as to allow access to detergent when the box body 100 is popped open.

[0043] In an embodiment of the present invention, the housing 100 and the lock assembly 300 may be directly or indirectly connected. When the housing 100 and the lock assembly 300 are directly connected, the housing 100 is adapted to directly abut against the lock assembly 300 when pushed and drive the lock assembly 300 to lock or unlock the housing 100. When the housing 100 and the lock assembly 300 are indirectly connected, the housing 100 is adapted to abut against the lock assembly 300 via the motion assembly 200 when pushed and drive the lock assembly 300 to lock or unlock the housing 100.

[0044] Reference Figures 1 to 3 The lock assembly 300 includes a push rod 310, a motion diverter 320 movably connected to the push rod 310, a lock pin 330 movably connected to the motion diverter 320, and a housing 301 suitable for accommodating the push rod 310, the motion diverter 320 and the lock pin 330.

[0045] Specifically, the housing 301 is located above the box body 100 and includes a top wall 301a, a bottom wall 301b, and a side wall 301c connecting the top wall 310a and the bottom wall 301b. The push rod 310 is partially housed in the housing 301. The motion diverter 320 is entirely housed in the housing 301 and rotatably mounted on the side wall 301c. The lock pin 330 is partially or entirely housed in the housing 301.

[0046] The push rod 310 is adapted to be pushed by the box body 100 and move along the first direction M1 when the box body 100 is pushed along the first direction M1 , and to push the motion diverter 320 to rotate when the box body 100 is pushed by the box body 100 and moves along the first direction M1 .

[0047] In a specific implementation, the motion diverter 320 and the box body 100 are respectively disposed on the upper and lower sides of the push rod 310. The push rod 310 may include a first contact portion 311 and a second contact portion 312 extending toward the box body 100 and the motion diverter 320, respectively.

[0048] The first contact portion 311 extends outside the housing 301 and is adapted to be abutted and pushed by the housing 100 to move in the first direction M1 when the housing 100 is pushed in the first direction M1. When the first contact portion 311 moves in the first direction M1, the entire push rod 310 moves in the first direction M1.

[0049] The second contact portion 312 is adapted to move with the push rod 310 when the push rod 310 moves along the first direction M1 so as to abut against the motion diverter 320 and push the motion diverter 320 to rotate.

[0050] The motion diverter 320 is movably connected to the push rod 310 and is adapted to rotate when pushed by the push rod 310 to abut against the locking pin 330 and push the locking pin 330 to move.

[0051] In a specific implementation, the motion diverter 320 may include a first arm 321, a second arm 322, and a rotation shaft 323 connecting the first arm 321 and the second arm 322. The rotation shaft 323 is fixed to the side wall 301c of the housing 301, and the first arm 321 and the second arm 322 are rotatably connected to the rotation shaft 323. For example, the first arm 321 and the second arm 322 are connected to the rotation shaft 323 via the same bearing and can rotate synchronously around the rotation shaft 323 via the bearing.

[0052] In the embodiment of the present invention, the first arm 321 is adapted to be abutted and rotated by the push rod 310 when the push rod 310 is pushed, and the second arm 322 is adapted to rotate with the first arm 321 to abut against the locking pin 300 and drive the locking pin 330 to move.

[0053] In a specific embodiment, the projections of the first arm 321 of the motion diverter 320 and the second contact portion 312 of the push rod 310 in a plane perpendicular to the first direction M1 and the second direction M2 at least partially overlap. This allows the first arm 321 to be pushed by the second contact portion 312 and rotate about the rotation axis 323 when the push rod 310 moves in the first direction M1.

[0054] The projections of the second arm 322 of the motion diverter 320 and the locking pin 330 in a plane perpendicular to the third direction M3 and the fourth direction M4 at least partially overlap. In this way, the second arm 322 can abut against the locking pin 300 and drive the locking pin 330 to move when rotating with the first arm 321.

[0055] In a specific implementation, the locking pin 330 may be configured to move along a third direction M3 and a fourth direction M4 opposite to the third direction.

[0056] In the embodiment of the present invention, the third direction M3 and the fourth direction M4 respectively have an included angle with the first direction M1 , and the included angle is within a range of 0 degrees to 180 degrees but does not include 0 degrees and 180 degrees.

[0057] In some preferred embodiments, the angle is 90 degrees, that is, the third direction M3 and the fourth direction M4 are respectively perpendicular to the first direction M1. For example, the first direction M1 is the front direction, the third direction M3 is the upper direction, and the fourth direction M4 is the lower direction.

[0058] For ease of explanation, in this embodiment of the present invention, the direction of movement of the locking pin 330 driven by the second arm 322 of the motion diverter 320 is collectively referred to as the third direction M3. Thus, the second arm 322 of the motion diverter 320 is adapted to abut against the locking pin 300 during rotation and drive the locking pin 330 to move along the third direction M3.

[0059] The locking pin 330 is movably connected to the motion diverter 320 , and is adapted to move along a third direction M3 to unlock the box body 100 or move along a fourth direction M4 to lock the box body 100 when pushed by the motion diverter 320 .

[0060] In a specific implementation, the locking pin 330 may include a third contact portion 332 and a locking tongue portion 333 .

[0061] The third contact portion 332 is adapted to be abutted by the second arm 322 of the motion diverter 320 when the motion diverter 320 rotates so that the locking pin 330 is pushed along the third direction M3.

[0062] In a specific embodiment, the projections of the second arm 322 and the third contact portion 332 of the motion diverter 320 in a plane perpendicular to the third direction M3 and the fourth direction M4 at least partially overlap. In this way, the second arm 322 can abut against the third contact portion 332 when rotating with the first arm 321, thereby driving the locking pin 330 to move along the third direction M3.

[0063] Reference Figure 7 and Figure 8 The box body 100 may include a locking groove 120 extending in the fourth direction M4. The locking groove 120 is provided corresponding to the locking tongue portion 333 of the locking pin 330 and is adapted to at least partially receive the locking tongue portion 333 to lock the box body 100 when the locking tongue portion 333 moves along the fourth direction M4.

[0064] Specifically, the locking tongue portion 333 is suitable for being received in the shell 301 or extending outside the shell 301 when the box body 100 is unlocked, suitable for extending into the locking slot 120 of the box body 100 along a fourth direction M4 opposite to the third direction M3 to restrict the box body 100 from moving along the first direction M1 or the second direction M2 opposite thereto to lock the box body 100, and also suitable for retracting from the locking slot 120 of the box body 100 along the third direction M3 to the outside of the box body 100 to release the restriction and unlock the box body 100.

[0065] Continue to refer to Figures 1 to 3 The lock pin 330 further includes a one-way rotation groove 331 located above the third contact portion 332. The lock assembly 300 further includes a first spring 340 connected between the housing 301 and the lock pin 330, and a swing hook 350 having a first end 351 fixed to the housing 301 and a second end 352 movable within the one-way rotation groove 331.

[0066] In a specific embodiment, the first spring 340 is always in a compressed state, and its two ends are respectively fixedly connected to the top wall 301a of the housing 301 and the end of the lock pin 330 away from its lock tongue portion 333. The swing hook 350 has a first end 351 and a second end 352. The first end 351 is fixedly connected to the top wall 301a of the housing 301, and the second end 352 is movably disposed in the one-way rotation groove 331.

[0067] Reference Figure 4 and Figure 5The one-way rotation groove 331 includes a first resting position A and a second resting position C. Under the action of the first spring 340, the second end 352 of the swing hook 350 can rest in the first resting position A or the second resting position C. When the lock pin 330 is pushed by the motion diverter 320, the second end 352 of the swing hook 350 can switch between the first resting position A and the second resting position C. When the second end 352 of the swing hook 350 is in the first resting position A, the lock pin 330 extends into the lock groove 120 of the box body. When the second end 352 of the swing hook 350 is in the second resting position C, the lock pin 350 is released from the lock groove 120.

[0068] In a specific embodiment, the one-way rotary groove 331 is a closed-loop groove, which also includes a first transition position B and a second transition position D located between the first rest position A and the second rest position C. The first rest position A, the first transition position B, the second rest position C, and the second transition position D are sequentially included in the closed-loop groove, and in the third direction M3, the height of the second rest position C is lower than the height of the first rest position A, but higher than the height of the first transition position B and the second transition position D.

[0069] In this way, the compression degree of the first spring 340 when the second end 352 of the swing hook 350 is at the second rest position C is greater than the compression degree when the second end 352 is at the first rest position A, and is less than the compression degree when the second end 352 is at the first transition position B and the second transition position D.

[0070] The one-way rotating groove 331 also includes a first rotating section 331a connecting the first rest position A and the first transition position B, a second rotating section 331b connecting the first transition position B and the second rest position C, a third rotating section 331c connecting the second rest position C and the second transition position D, and a fourth rotating section 331d connecting the second transition position D and the first rest position A.

[0071] Reference Figure 6 The groove depth of the first rotating section 331a gradually becomes shallower along the direction from the first rest position A to the first transition position B, the groove depth of the second rotating section 331b gradually becomes shallower along the direction from the first transition position B to the second rest position C, the groove depth of the third rotating section 331c gradually becomes shallower along the direction from the second rest position C to the second transition position D, and the groove depth of the fourth rotating section 331d gradually becomes shallower along the direction from the second transition position D to the first rest position A.

[0072] The groove depth transitioning from the first turning segment 331a to the second turning segment 331b suddenly changes and deepens at the first transition position B, the groove depth transitioning from the second turning segment 331b to the third turning segment 331c suddenly changes and deepens at the second rest position C, the groove depth transitioning from the third turning segment 331c to the fourth turning segment 331d suddenly changes and deepens at the second transition position D, and the groove depth transitioning from the fourth turning segment 331d to the first turning segment 331a suddenly changes and deepens at the first rest position A.

[0073] Reference Figure 7 When the box body 100 is in the unlocked state, the second end 352 of the swing hook 350 stays at the second rest position C. At this time, if the second arm 322 of the motion diverter 320 drives the lock pin 330 to move in the third direction M3, the first spring 340 is squeezed by the lock pin 330 in the third direction M3 and compressed in the third direction M3. At the same time, the second end 352 of the swing hook 350 moves from the second rest position C to the second transition position D along the third rotation section 331c of the one-way rotation groove 331.

[0074] Because the height of the second transition position D is lower than the heights of the adjacent third and fourth rotation segments 331c and 331d in the third direction M3, the second end 352 of the swing hook 350 cannot move further downward in the third direction M3, thereby preventing the first spring 340 from being further compressed. At this point, since the first spring 340 is in a compressed state, it automatically extends in a direction to release the compression, that is, in a fourth direction M4 opposite to the third direction M3.

[0075] When the first spring 340 extends in the fourth direction M4, it drives the locking pin 330 to move in the fourth direction M4. When the locking pin 330 moves in the fourth direction M4, it drives the second end 352 of the swing hook 350 to move from the second transition position D to the first rest position A along the fourth rotation section 331d of the one-way rotation groove 331.

[0076] Since the groove depth transitioning from the third rotating segment 331c to the fourth rotating segment 331d suddenly changes and becomes deeper at the second transition position D, the second end 352 of the swing hook 350 is more likely to move to the fourth rotating segment 331d rather than the third rotating segment 331c when in the second transition position D. This is because if the second end 352 of the swing hook 350 cannot cross the sudden change in groove depth between the fourth rotating segment 331d and the third rotating segment 331c at the second transition position D, it will be unable to move from the second transition position D to the third rotating segment 331c.

[0077] Because the first resting position A is higher than the adjacent fourth rotation segment 331d and first rotation segment 331a in the third direction M3, the second end 352 of the swing hook 350 cannot move to a higher position in the third direction M3, thereby preventing the first spring 340 from further extending. Furthermore, because the first spring 340 remains compressed, the second end 352 of the swing hook 350 remains at the first resting position A. At this point, the locking tongue portion 333 of the locking pin 330 is inserted into the locking slot 120 of the case body 100, locking it.

[0078] Reference Figure 8When the case 100 is locked, the second end 352 of the swing hook 350 remains at the first resting position A. At this time, if the second arm 322 of the motion diverter 320 drives the lock pin 330 to move in the third direction M3, the first spring 340 is squeezed by the lock pin 330 in the third direction M3 and compressed in the third direction M3. Simultaneously, the second end 352 of the swing hook 350 moves along the first rotation section 331a of the one-way rotation groove 331 from the first resting position A to the first transition position B. At this time, the lock tongue portion 333 of the lock pin 330 retracts from the lock groove 120 of the case 100 in the third direction M3 to the outside of the case 100, unlocking the case 100.

[0079] Because the height of the first transition position B is lower than the heights of the adjacent first and second rotating segments 331a, 331b in the third direction M3, the second end 352 of the swing hook 350 cannot move downward in the third direction M3, thereby preventing the first spring 340 from being further compressed. At this point, since the first spring 340 is in a compressed state, it automatically extends in a direction to release the compression, that is, in a fourth direction M4 opposite to the third direction M3.

[0080] When the first spring 340 extends in the fourth direction M4, it drives the locking pin 330 to move in the fourth direction M4. When the locking pin 330 moves in the fourth direction M4, it drives the second end 352 of the swing hook 350 to move along the second rotation section 331b of the one-way rotation groove 331 from the first transition position B to the second rest position C.

[0081] Since the groove depth transitioning from the first rotating segment 331a to the second rotating segment 331b suddenly changes and becomes deeper at the first transition position B, the second end 352 of the swing hook 350 is more likely to move to the second rotating segment 331b rather than the first rotating segment 331a when in the first transition position B. This is because if the second end 352 of the swing hook 350 cannot cross the sudden change in groove depth between the second rotating segment 331b and the first rotating segment 331a at the first transition position B, it will be unable to move from the first transition position B to the first rotating segment 331a.

[0082] Because the second rest position C is higher than the adjacent second rotation segment 331b and third rotation segment 331c in the third direction M3, the second end 352 of the swing hook 350 cannot move to a higher position in the third direction M3, thereby preventing the first spring 340 from further extending. At this time, the locking tongue portion 333 of the locking pin 330 is located outside the box body 100 and disengaged from the locking slot 120 of the box body 100, thereby placing the box body 100 in an unlocked state.

[0083] exist Figures 1 to 8In the illustrated example, the second end 352 of the swing hook 350 consistently moves counterclockwise within the one-way rotation groove 331. It should be understood that this is merely an example and does not constitute a limitative interpretation of the technical solutions of the embodiments of the present invention. In other examples, by varying the depth of the one-way rotation groove 331 in each rotational section, the second end 352 of the swing hook 350 can also be caused to consistently move clockwise within the one-way rotation groove 331.

[0084] In the embodiment of the present invention, the motion assembly 200 is adapted to drive the box body 100 to pop out along a second direction M2 opposite to the first direction M1 to open when the box body 100 is unlocked.

[0085] Reference Figure 1 、 Figure 7 and Figure 8 The motion assembly 200 includes a rack 210 connected to the box body 100 , a gear 220 meshing with the rack 210 , and an energy storage device 230 connected to the gear 220 .

[0086] The rack 210 is adapted to move along the first direction M1 when the box body 100 is pushed along the first direction M1 to drive the gear 220 to rotate along the first rotation direction (eg, counterclockwise), thereby driving the energy storage device 230 to store energy.

[0087] In a specific implementation, the rack 210 can be located above the box body 100 and have a clamping portion 211 extending toward the direction of the box body 100, and the box body 100 has a receiving portion 110 that cooperates with the clamping portion 211. The rack 210 and the box body 100 are engaged by the clamping portion 211 being clamped in the receiving portion 110.

[0088] The energy storage device 230 is adapted to release energy when the box body 100 is unlocked to drive the gear 220 to rotate in a second rotation direction (e.g., clockwise) opposite to the first rotation direction, so that the rack 210 pulls the box body 100 to pop out in a second direction M2 opposite to the first direction M1.

[0089] In a specific implementation, the energy storage device 230 includes energy storage components such as a tension spring and / or a coil spring to store or release energy.

[0090] In some preferred specific examples, the energy storage device 230 may further include a damping component connected to the energy storage component, such as a mass block, a flywheel, etc. The damping component is adapted to move with the energy storage component and consume the energy stored in the energy storage component, thereby reducing the rotational speed of the gear 220 in the second rotational direction and reducing the speed of the rack 210 moving in the second direction M2, so that the box body 100 is smoothly ejected in the second direction M2.

[0091] Reference Figure 7 and Figure 8The detergent box assembly 10 further includes a housing 400 adapted to support the box body 100 , the moving assembly 200 and the lock assembly 300 .

[0092] In a specific implementation, the box body 100 is accommodated and supported in the space enclosed by the shell 400. The shell 400 is open at one side located at the front end of the box body 100, so that the box body 100 can be ejected forward relative to the shell 400 to open or pushed backward to close.

[0093] The lock assembly 300 is fixed to the outside of the housing 400 and is located above the housing 400. The housing 400 is provided with a hole corresponding to the lock slot 120 of the box body 100 and the lock tongue portion 333 of the lock pin 300, which is suitable for allowing the lock tongue portion 333 of the lock pin 330 to pass through and be inserted into the lock slot 120 of the box body 100.

[0094] The gear 220 and the energy storage device 230 of the motion assembly 200 are fixed in the housing 400, and the rack 210 of the motion assembly 200 is at least partially accommodated in the housing 400. The housing 400 further includes a support member 410 accommodated in the space enclosed by the housing 400 and located above the box body 100, which is suitable for movably supporting the rack 210 thereon.

[0095] In the embodiment of the present invention, the first contact portion 311 of the push rod 310 may also be movably connected to the motion component 200 and moved by the motion component 200 .

[0096] In a specific implementation, the first contact portion 311 of the push rod 310 can be movably connected to the rear end of the rack 210 of the motion assembly 200. The first contact portion 311 of the push rod 310 is adapted to be abutted and pushed by the rack 210 when the rack 210 moves along the first direction M1 with the box body 100.

[0097] In other embodiments not shown in the drawings, the push rod 310 may also be directly pushed by the case body 100. For example, the first contact portion 311 of the push rod 310 may be movably connected to the case body 100. When the case body 100 moves in a first direction M1, the first contact portion 311 of the push rod 310 contacts the first contact portion 311 of the push rod 310 and pushes the push rod 310 to move in the first direction M1. Thereafter, when the case body 100 moves in a second direction M2 opposite to the first direction M1, the case body 100 separates from the first contact portion 311 of the push rod 310.
