It may be understood that the pull-out box 30 may alternatively be arranged in another region of the front wall 101 of the laundry care device 100 as required. A control portion, a display portion, and the like may be arranged on the control panel. The control portion may be a touch control or a mechanical control such as a knob or a button.

[0035] FIG. 3 shows a pull-out box 30, where the pull-out box 30 has a box body 30a and a handle assembly 30b that are exemplarily shown. The box body 30a is configured to receive a detergent in a liquid state and / or a gel state and / or a powder state. The handle assembly 30b is mounted on the box body 30a.

[0036] The handle assembly 30b includes a decorative cover 31, a handle 32, a base board 33, and an engaging mechanism 34 located between the handle 32 and the base board 33. The base board 33 is fixedly connected to the box body 30a. For example, the base board 33 includes at least one connecting element 331, where the at least one connecting element 331 is configured to connect the handle assembly 30b to the box body 30a, thereby forming the pull-out box 30. The handle 32 is slidably connected to the base board 33 along the pull-out direction D and has a holding position away from the base board 33 and a closed position close to the base board 33. The engaging mechanism 34 is capable of keeping the handle 32 in the holding position and the closed position separately.

[0037] The handle 32 includes a holding portion 321. For example, the handle assembly 30b includes only one handle 32 and one holding portion 321. In other embodiments, the handle assembly 30b may alternatively have a plurality of handles 32 and a plurality of holding portions 321. The holding portion 321 is preferably constructed in a lower region of the handle 32. After the pull-out box 30 is mounted in place on the laundry care device 100, the engaging mechanism 34 can convert the handle 32 between the first state and the second state. As shown in FIG. 1, in the first state, the handle 32 and the holding portion 321 are substantially received in the housing 10, and the handle 32 is in the closed position. As shown in FIG. 2, in the second state, the handle 32 and the holding portion 321 protrude from the housing outside 11 of the laundry care device 100 adjacent to the handle 32, and the handle 32 is in the holding position. In this case, a user can reach the holding portion 321 and operate the handle 32 through the holding portion 321 to open or close the box body 30a of the pull-out box 30.

[0038] The decorative cover 31 is arranged toward the housing outside 11. The decorative cover 31 may be constructed in one piece or formed by a plurality of sub-elements. The decorative cover 31 and the housing outside 11 (especially the front wall 101) of the laundry care device 100 preferably have similar and / or identical and / or consistent characteristics (or compositions), including but not limited to color compositions, material compositions, and the like. The decorative cover 31 is arranged at least on the handle 32.

[0039] For example, the handle 32 covers an entire surface of the base board 33, and the decorative cover 31 is substantially constructed as a plate and fastened to the handle 32 by bonding or another manner, to cover the handle 32. In the first state, an outer side of the decorative cover 31 forms an entire outer side of the handle assembly 30b, so that there is no division line on the entire outer side of the handle assembly 30b. Preferably, in the first state, the outer side of the decorative cover 31 is flush with the housing outside 11 of the laundry care device 100 adjacent to the decorative cover 31. In other embodiments, the handle 32 may cover only a part of the base board 33, and the decorative cover 31 includes a first decorative cover arranged on the handle 32 and a second decorative cover arranged on the remaining part of the base board 33. In the first state, outer sides of the first decorative cover and the second decorative cover form the entire outer side of the handle assembly 30b, and are both flush with the housing outside 11 of the laundry care device 100 adjacent to the decorative cover 31. Therefore, a substantially coherent front wall 101 or a flat front wall is visually created. In the front wall, substantially only the door unit 20 protrudes from the housing outside 11 of the front wall 101 of the laundry care device 100. Preferably, the outer side of the decorative cover 31 is substantially a plane. When the housing outside 11 of the laundry care device 100 is also substantially a plane, the laundry care device 100 has a fashionable and neat design.

[0040] It may be understood that the decorative cover 31 may not be arranged, and instead the handle 32 or the handle 32 and an outer side of the base board 33 form the outer side of the handle assembly 30b. In this case, the handle 32 and / or the base board 33 and the housing outside 11 (especially the front wall 101) of the laundry care device 100 preferably have similar and / or identical and / or consistent characteristics (or compositions).

[0041] With reference to FIG. 4 and FIG. 5, the engaging mechanism 34 includes a driving mechanism 341. The driving mechanism 341 can provide a driving force for converting the handle between the first state (the closed position) and the second state (the holding position). For example, the driving mechanism 341 is constructed as a push-push locking assembly 3411 and at least one elastic element 3412. The at least one elastic element 3412 may be a spring element or a spring-like element, which may be tensioned. In the current embodiment, the elastic element 3412 is constructed as a compression spring. Other spring-like elements are also feasible. The elastic element 3412 in this embodiment is shown in a substantially relaxed state in FIG. 4. In other embodiments, the driving mechanism 341 may alternatively be constructed as a micro-motor driving mechanism, an electromagnetic driving mechanism, or the like.

[0042] The push-push locking assembly 3411 preferably includes a snap-lock element 3411a and a locking element 3411b, one of which is arranged on the base board 33, and the other of which is constructed on the handle 32. The locking element 3411b may be constructed as, for example, a locking hook and / or a locking pin. The locking element 3411b is constructed to be receivable by the snap-lock element 3411a, or the locking element 3411b is constructed to be pushable into the snap-lock element 3411a, so that the locking element 3411b is received in the snap-lock element 3411a. If the locking element 3411b is pushed into or received in the snap-lock element 3411a, the handle 32 is kept in the closed position.

[0043] In the first state of the handle 32 in FIG. 1, the elastic element 3412 is tensioned. In the second state of the handle 32 in FIG. 2, the elastic element 3412 is relaxed. After the locking element 3411b is unlocked from the snap-lock element 3411a, the elastic element 3412 causes the handle 32 to be pressed open / out. The elastic element 3412 is arranged between the handle 32 and the base board 33. Optionally, the elastic element 3412 is arranged on the base board 33 and abuts against the handle 32 and / or the decorative cover 31.

[0044] The engaging mechanism 34 further includes a sliding mechanism 342, and the handle 32 is slidably supported on the base board 33 along the sliding mechanism 342. The sliding mechanism 342 includes a guide rail 3421 and a protruding element 3422. One of the guide rail 3421 and the protruding element 3422 is constructed on the handle 32, and the other is constructed on the base board 33. For example, the guide rail 3421 is a guide hole, and the protruding element 3422 is a guide column that passes through the guide hole and slides along an inner peripheral surface of the hole. The guide rail 3421 is arranged on the base board 33, and the protruding element 3422 is arranged on the handle 32. The protruding element 3422 is guided or supported in a guided manner in the guide rail 3421. In this embodiment, four guide rails 3421 and four protruding elements 3422 are constructed, which are preferably constructed in four peripheral regions of the base board 33 and four peripheral regions of the handle 32 respectively. It may be understood that a quantity of guide rails 3421 and a quantity of protruding elements 3422 may alternatively be set as required, and the quantity of protruding elements 3422 matches the quantity of guide rails 3421.

[0045] The engaging mechanism 34 further includes a positioning mechanism 343 and a limiting mechanism 344. The positioning mechanism 343 includes a first positioning assembly 3431 and a second positioning assembly 3432. The limiting mechanism 344 includes a first limiting assembly 3441 and a second limiting assembly 3442. The handle 32 is positioned and limited in the holding position through the first positioning assembly 3431 and the first limiting assembly 3441, and is positioned and limited in the closed position through the second positioning assembly 3432 and the second limiting assembly 3442.

[0046] FIG. 6 and FIG. 7 are a schematic diagram and a cross-sectional view of the handle assembly 30b in the closed position. In the closed position, a gap and a step corresponding to a case that the handle 32 and the base board 33 are accommodated in the housing 10 are ensured through the first positioning assembly 3431, so that appearance consistency is better. For example, the first positioning assembly 3431 includes a first positioning rib 3431a and a second positioning rib 3431b that match each other and that are respectively arranged on the handle 32 and the base board 33. The first positioning rib 3431a and the second positioning rib 3431b define displacements of the handle 32 relative to the base board 33 in horizontal and vertical directions on a plane perpendicular to the pull-out direction D. In other embodiments, displacements in at least two other directions may alternatively be defined.

[0047] The handle 32 and the base board 33 are limited in the pull-out direction in the closed position through the first limiting assembly 3441. As shown in FIG. 4 and FIG. 5, for example, the first limiting assembly 3441 includes locking portions of the snap-lock element 3411a and the locking element 3411b.

[0048] FIG. 8 to FIG. 10 are schematic diagrams and a cross-sectional view of the handle assembly 30b in the holding position. In the holding position, it is ensured through the second positioning assembly 3432 that the handle 32 and the base board 33 do not shake when being pulled open. For example, the second positioning assembly 3432 includes fitting portions of the protruding element 3422 and the guide rail 3421 in a circumferential direction in the holding position, including a protruding element fitting portion 3432a and a guide rail fitting portion 3432b. Preferably, the protruding element fitting portion 3432a is an outer periphery of at least two radially extending bosses arranged on an outer periphery at an end of the protruding element 3422 away from the handle 32, and the guide rail fitting portion 3432b is an inner periphery of the guide rail 3421. A boss is used as a positioning portion, which facilitates manufacturing, and there is no need to control the entire outer periphery at the end of the protruding element 3422 away from the handle 32.

[0049] In this embodiment, an inner peripheral surface of the guide hole used as the guide rail 3421 is a first cylindrical surface, an outer peripheral surface of the guide column used as the protruding element 3422 is a tapered surface, and a diameter at an end of the tapered surface close to the handle 32 is less than a diameter of an end at the tapered surface away from the handle 32. At least two bosses are arranged on an outer periphery at the end of the tapered surface away from the handle 32, outer peripheral surfaces of the at least two bosses are each a part of a second cylindrical surface, and diameters of the first cylindrical surface and the second cylindrical surface are substantially the same. Therefore, there is a gap between the guide rail 3421 and the protruding element 3422 in the first state, so that there is no much resistance during the movement, and the tapered transition gradually occurs, so that no large shaking occurs during the movement, and the positioning during opening is implemented.

[0050] The handle 32 and the base board 33 are limited in the pull-out direction in the holding position through the second limiting assembly 3442.

[0051] For example, the second limiting assembly 3442 includes a snap 3442a at an end portion of the protruding element 3422 away from the handle 32 and an end surface 3442b of the guide rail 3421 that fits the snap 3442a in the holding position.

[0052] The following briefly describes how the handle 32 and the decorative cover 31 are converted from the first state to the second state. The handle 32 and the decorative cover 31 are in the first state, in which the handle 32 and the decorative cover 31 are substantially received in the housing 10 of the laundry care device 100, and the handle 32 and the decorative cover 31 are in the closed position. By pressing the decorative cover 31 from the outside, the locking element 3411b is disengaged from the snap-lock element 3411a. The elastic element 3412 tensioned in the first state causes the handle 32 and the decorative cover 31 to be pressed out. Because the handle 32 and the decorative cover 31 are slidably supported on the base board 33 through the sliding mechanism 342, the handle 32 and the decorative cover 31 are slidably moved and smoothly converted from the first state to the second state through the elastic element 3412. In the second state, the handle 32 and the decorative cover 31 extend from the housing 10 of the laundry care device 100 in such a way that the holding portion 321 of the handle 32 can be operated from the outside, that is, the handle 32 and the decorative cover 31 are in the holding position. The pull-out box 30 may be pulled out from the housing 10 of the laundry care device 100 through the holding portion 321. In a contrary process, that is, in a case that the handle 32 and the decorative cover 31 move from the second state to the first state, the handle 32 and the decorative cover 31 are pressed in, so that the elastic element 3412 is tensioned again and the locking element 3411b is received in the snap-lock element 3411a. The handle 32 and the decorative cover 31 are received in the laundry care device 100 in the first state.

[0053] Although specific implementations have been described above, these implementations are not intended to limit the scope of this application, even if only one implementation is described with respect to specific features. The feature example provided in this application is intended to be illustrative rather than limiting, unless otherwise stated. In specific implementation, a plurality of features may be combined with each other according to actual requirements and in a technically feasible manner. Modifications in any form made to this application by a person of ordinary skill in the art without departing from the basic technical idea of this application shall all fall within the protection scope of this application.
