DETAILED DESCRIPTION

[0024] Embodiments of the present disclosure will be described in detail below with reference to examples thereof as illustrated in the accompanying drawings, throughout which same or similar elements, or elements having same or similar functions, are denoted by same or similar reference numerals. The embodiments described below with reference to the drawings are illustrative only, and are intended to explain, rather than limiting, the present disclosure.

[0025] A liquid storage box assembly 1 according to the embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0026] As illustrated in FIG. 1 to FIG. 4, the liquid storage box assembly 1 according to the embodiments of the present disclosure may include a detergent box 100 and a dispenser box 200.

[0027] In some examples, the liquid storage box assembly 1 may be disposed in a laundry treatment device and configured to store a laundry treatment agent. For example, the liquid storage box assembly 1 is disposed in a washing machine. The liquid storage box assembly 1 is formed as a detergent box assembly of the washing machine. The liquid storage box assembly 1 includes the detergent box 100 and the dispenser box 200. The dispenser box 200 is movably engaged in the detergent box 100 in a drawable manner. The dispenser box 200 is configured to store a detergent and is openable or closable by drawing the dispenser box 200, thereby achieving filling of the detergent. In this way, it is convenient to quantitively dispense the detergent into a washing tub of the washing machine in batches by means of the liquid storage box assembly 1.

[0028] For example, the liquid storage box assembly 1 is applied in a clothes dryer. The liquid storage box assembly 1 is formed as a water box of the clothes dryer. The water box of the clothes dryer is used for collecting condensed water generated by condensation during drying and requires regular cleaning by a user. That is, the liquid storage box assembly 1 includes the detergent box 100 and the dispenser box 200. The dispenser box 200 is movably engaged in the detergent box 100 in a drawable manner. The dispenser box 200 is configured to store the condensed water and is openable or closable by drawing the dispenser box 200, thereby realizing the regular cleaning of the collected condensed water.

[0029] In some embodiments, the detergent box 100 may have an accommodation cavity with an opening at a side of the accommodation cavity. The dispenser box 200 is movably engaged in the accommodation cavity in a drawable manner, to achieve opening or closing of the dispenser box 200. In this way, the dispensing of the detergent to the dispenser box 200 is facilitated. At least one of the detergent box 100 and the dispenser box 200 may be provided with a rolling member. For example, the rolling member may be a roller. Further, the other one of the detergent box 100 and the dispenser box 200 may have an inclined guide surface. The inclined guide surface is in contact and engaged with the rolling member. That is, the rolling member and the inclined guide surface may roll relative to each other. Specifically, the inclined guide surface obliquely extends downwards in an opening direction of the dispenser box 200 (the opening direction is illustrated in FIG. 1). For example, when the dispenser box 200 may move in a front-rear direction in a horizontal plane, the inclined guide surface gradually and obliquely extends downwards in the front-rear direction. In other words, the dispenser box 200 has a trend of moving forwards and downwards during its opening.

[0030] It should be understood herein that in some examples the detergent box 100 may be provided with the rolling member, and the dispenser box 200 may have the inclined guide surface corresponding to the rolling member. In other examples, the dispenser box 200 may be provided with the rolling member, and the detergent box 100 may have the inclined guide surface corresponding to the rolling member. In yet other examples, the detergent box 100 and the dispenser box 200 may be provided with a first rolling member and a second rolling member, respectively. The dispenser box 200 may have a first inclined guide surface corresponding to the first rolling member, and the detergent box 100 may have a second inclined guide surface corresponding to the second rolling member.

[0031] With the liquid storage box assembly 1 according to the embodiments of the present disclosure, by providing the detergent box 100 and the dispenser box 200, pre-storage of the detergent can be realized. During each laundry, the detergent may be quantitatively poured into the washing tub in batches based on washing requirements, eliminating a hassle that users have to fetch a detergent bag (or a detergent container), open the detergent bag (or the detergent container), and dispense the detergent every time they do the laundry. The arrangement of the liquid storage box assembly 1 makes laundry more convenient and simplifies user's operation.

[0032] Moreover, by providing the dispenser box 200 and/or the detergent box 100 with the rolling member, a drawing action of the dispenser box 200 can be implemented through rolling of the rolling member. As a result, it is possible to reduce frictional resistance between the dispenser box 200 during opening and closing of the detergent box 100, allowing the dispenser box 200 to move smoothly and flexibly. Further, since the dispenser box 200 and/or the detergent box 100 also has the inclined guide surface corresponding to the rolling member, during opening of the dispenser box 200, the dispenser box 200 may have a tendency to open downwards and forwards under the action of gravity, thereby achieving its automatic opening along the inclined guide surface. Moreover, it is convenient to open the dispenser box 200 smoothly and fully. That is, the dispenser box 200 can be fully opened. In particular, when the dispenser box 200 is full of the detergent, quick and automatic opening of the dispenser box 200 can be realized. Therefore, convenience and comfortableness of use is improved, and user's experience is facilitated.

[0033] It should be understood that the phase "fully opening the dispenser box 200" refers to opening the dispenser box 200 to its outermost position. At this time, a pick-and-place opening of the dispenser box 200 is completely exposed. Certainly, in some other specific examples, the pick-and-place opening of the dispenser box 200 may also be completely exposed before the dispenser box 200 reaches the outermost position.

[0034] Therefore, the liquid storage box assembly 1 according to the embodiments of the present disclosure has advantages such as ease of fully opening the dispenser box 200, user-friendly operation, and a comfortable user experience.

[0035] A liquid storage box assembly 1 according to a specific embodiment of the present disclosure will be described below with reference to the accompanying drawings.

[0036] In some specific embodiments of the present disclosure, as illustrated in FIG. 1 to FIG. 4, the liquid storage box assembly 1 according to the embodiment of the present disclosure may include a detergent box 100 and a dispenser box 200.

[0037] In some embodiments, one of the detergent box 100 and the dispenser box 200 is provided with a rolling member, and the other one of the detergent box 100 and the dispenser box 200 is provided with a guide portion. An inclined guide surface is formed at the guide portion. In this way, a movement trajectory of the dispenser box 200 can be positioned and guided by using the guide portion to improve accuracy and reliability of operations of the dispenser box 200. Further, processing of the inclined guide surface is also facilitated. In addition, it is convenient to form a support engagement between the inclined guide surface and the rolling member, thereby ensuring that the rolling member is movable in an extending direction of the inclined guide surface.

[0038] Optionally, a side of the detergent box 100 facing towards the dispenser box 200 is provided with a rolling member. The rolling member is a roller. A bottom of the dispenser box 200 is provided with a guide portion. The roller is engaged with the guide portion. The roller and the guide portion may roll relative to each other to achieve drawing of the dispenser box 200. The guide portion may be formed as a planar structure or a groove structure. In some specific examples, the guide portion is formed as a guide groove, and the inclined guide surface is located at a bottom of the guide groove. Specifically, the detergent box 100 has an opening defined at a front side surface thereof. The dispenser box 200 is movable in a drawable manner in the front-rear direction. In this way, the inclined guide surface gradually and obliquely extends downwards from back to front. An angle of the inclined guide surface relative to the front-rear direction may be set to be smaller than or equal to 10 degrees. For example, the angle of the inclined guide surface relative to the front-rear direction may be 2 degrees, 3 degrees, or 5 degrees. In this way, during forward drawing of the dispenser box 200, it is convenient to allow for an automatically forward movement of the dispenser box 200 under the action of gravity. As a result, the automatic opening of the dispenser box 200 is realized. Further, the smooth and full opening of the dispenser box 200 is facilitated.

[0039] Specifically, in the opening direction of the dispenser box 200, a length of the inclined guide surface is 1, and a length of the guide portion is L, where l≥0.5 L. that is, the length of the inclined guide surface is at least greater than or equal to half of the length of the guide portion.

[0040] Optionally, the dispenser box 200 may move in the front-rear direction. The guide portion extends in the front-rear direction. In the front-rear direction, the length of the inclined guide surface is 1, and the length of the guide portion is L, i.e., a length of a contactable engagement region between the dispenser box 200 and the roller, where l≥0.6L, l≥0.7L, or l≥0.8L.

[0041] In some embodiments, as illustrated in FIG. 4, one of the detergent box 100 and the dispenser box 200 is provided with the rolling member, and the other one of the detergent box 100 and the dispenser box 200 has a limiting surface 220. The limiting surface 220 has an end connected to the inclined guide surface and obliquely extending upwards in the opening direction of the dispenser box 200. In this way, the limiting surface 220 can not only be used to provide the movement of the dispenser box 200 with a buffering effect, but can also supply a reaction force to prevent the dispenser box 200 from title downwards.

[0042] Optionally, as illustrated in FIG. 4, the side of the detergent box 100 facing towards the dispenser box 200 is provided with a first roller 110. The bottom of the dispenser box 200 has the guide groove. The roller is engaged in the guide groove. The roller and the guide groove is movable relative to each other to achieve the drawing movement of the dispenser box 200. The inclined guide surface and the limiting surface 220 are located at the bottom of the guide groove. Specifically, the detergent box 100 has the opening defined at the front side surface thereof (the front-rear direction is illustrated in FIG. 1). The dispenser box 200 is movable in a drawable manner in the front-rear direction. Therefore, the inclined guide surface gradually and obliquely extends downwards from back to front (an up-down direction is illustrated in FIG. 1). The limiting surface 220 is located behind the inclined guide surface and gradually and obliquely extends upwards from back to front.

[0043] Specifically, as illustrated in FIG. 4, the inclined guide surface has an extending length greater than an extending length of the limiting surface 220. A lower end of the inclined guide surface is flush with a lower end of the limiting surface 220. In this way, it is convenient to achieve the full opening of the dispenser box 200 automatically and smoothly. Moreover, overall stability of the opened dispenser box 200 can be ensured.

[0044] In some optional examples, as illustrated in FIG. 4, one of the detergent box 100 and the dispenser box 200 is provided with the rolling member, and the other one of the detergent box 100 and the dispenser box 200 has an engagement guide surface 230. The engagement guide surface 230 has an end connected to the limiting surface 220 and another end extending horizontally. In this way, it is possible to further ensure the overall stability of the opened dispenser box 200.

[0045] Specifically, as illustrated in FIG. 4, the side of the detergent box 100 facing towards the dispenser box 200 is provided with the first roller 110. The bottom of the dispenser box 200 is provided with a first guide portion. The first roller 110 is engaged in the first guide portion. The first roller 110 and the first guide portion may roll relative to each other to achieve the drawing movement of the dispenser box 200. The inclined guide surface, the limiting surface 220, and the engagement guide surface 230 are sequentially located at the guide portion. Specifically, the opening of the detergent box 100 is formed at the front side surface thereof. The dispenser box 200 is movable in a drawable manner in the front-rear direction. The engagement guide surface 230 is located behind the limiting surface 220.

[0046] In some embodiments, as illustrated in FIG. 4, the rolling member may include a first roller 110. The first roller 110 is disposed at the detergent box 100. The inclined guide surface may include a first guide surface 210. The first guide surface 210 is located at the dispenser box 200. The first roller 110 is in contact and engaged with the first guide surface 210. That is, a support engagement between the first roller 110 and the first guide surface 210 can be realized, and relative rolling between the first roller 110 and the first guide surface 210 can be carried out. In this way, a reduction in relative friction between the dispenser box 200 and the detergent box 100 can be facilitated, thereby achieving a smooth movement and automatic opening of the dispenser box 200.

[0047] Specifically, as illustrated in FIG. 4, the rolling member 110 includes at least two first rollers 110. The at least two first rollers 110 are arranged at intervals in the opening direction of the dispenser box 200. Some of the at least two first rollers 110 are arranged at a side of the detergent box 100 close to the opening, and the rest of the at least two first rollers 110 are arranged at a side of the detergent box 100 facing away from the opening. In this way, it is convenient to support the dispenser box 200 and improve structural stability and reliability of the dispenser box 200.

That is, a support engagement between the second roller 240 and the second guide surface can be realized, and relative rolling movement between the second roller 240 and the second guide surface can be carried out. In this way, a reduction in the relative friction between the dispenser box 200 and the detergent box 100 is facilitated, thereby realizing the smooth movement and automatic opening of the dispenser box 200. Further, the second guide surface and the first guide surface 210 are parallel to each other and arranged side by side. In this way, it is possible to ensure that the dispenser box 200 can be drawn smoothly.

[0049] Further, the rolling member includes at least two second rollers 240. The at least two second rollers 240 are arranged at intervals in the opening direction of the dispenser box 200. Some of the second rollers 240 are disposed at a side of the dispenser box 200 facing away from the opening, and the rest of the second rollers 240 are disposed at a side of the dispenser box 200 close to the opening. In this way, support for the dispenser box 200 is further facilitated, thereby enhancing the structural stability and reliability of the dispenser box 200. Therefore, the dispenser box 200 can smoothly move and is prevented from shaking during its movement.

[0050] For example, the opening of the detergent box 100 is formed at the front side surface thereof. The rolling member includes two second rollers 240.

[0060] When the dispenser box 200 is movable in the drawable manner in the front-rear direction, the first guide surface and the second guide surface each gradually and obliquely extend downwards from back to front. An angle of the first guide surface relative to the front-rear direction may be set to be smaller than or equal to 10 degrees. For example, the angle of the first guide surface relative to the front-rear direction may be 2 degrees, 3 degrees, or 5 degrees. Similarly, an angle of the second guide surface relative to the front-rear direction may be set to be smaller than or equal to 10 degrees. For example, the angle of the second guide surface relative to the front-rear direction may be 2 degrees, 3 degrees, or 5 degrees. In this way, during the drawing of the dispenser box 200 to open the dispenser box 200, it is possible to allow the dispenser box 200 to automatically move forwards under the gravity, thereby achieving the automatic opening of the dispenser box 200. Moreover, the smooth and full opening of the dispenser box 200 is facilitated.

[0061] In the opening direction of the dispenser box 200, the length of the inclined guide surface is 1, and the length of the guide portion is L, where l≥0.5 L. That is, the length of the inclined guide surface is at least greater than or equal to half of the length of the guide groove. Specifically, the dispenser box 200 is movable in the front-rear direction. The first guide groove extends in the front-rear direction. In the front-rear direction, the length of the first guide groove is 11, and the length of the first guide groove is L1, i.e., the length of the first guide groove is a length of the contactable engagement region between the dispenser box 200 and the roller, where l1≥0.6L1, l1≥0.7L1, or l1≥0.8L1. Similarly, the second guide groove extends in the front-rear direction. In the front-rear direction, a length of the second guide surface is l2, and a length of the second guide groove is L2, i.e., the length of the second guide groove is a length of a contactable engagement region between the dispenser box 200 and the roller, where l2≥0.6L2, l2≥0.7L2, or l2≥0.8L2.

[0062] The first guide groove has a first limiting surface 220. The first limiting surface 220 has a front end connected to the first guide surface 210 and a rear end extending in an inclination direction opposite to the first guide surface 210. Similarly, the second guide groove has a second limiting surface 220. The second limiting surface 220 has a rear end connected to the second guide surface and a front end extending in an inclination direction opposite to the second guide surface. In this way, not only the movement of the dispenser box 200 can be buffered by using the limiting surface 220, but also the limiting surface 220 can also provide a reaction force to prevent the dispenser box 200 from titling downwards as a whole.

[0063] That is, the first guide surface 210 gradually and obliquely extends downwards from back to front. The first limiting surface 220 is located behind the inclined guide surface. Further, the first limiting surface 220 gradually and obliquely extends upwards from back to front. The second guide surface gradually and obliquely extends downwards from back to front. The second limiting surface 220 is located in front of the inclined guide surface. Further, the second limiting surface 220 gradually and obliquely extends upwards from back to front.

[0064] The first guide surface 210 has an extending length greater than an extending length of the first limiting surface 220. A lower end of the first guide surface 210 is flush with the lower end of the first limiting surface 220. Similarly, the second guide surface has an extending length greater than an extending length of the second limiting surface 220. A lower end of the second guide surface is flush with a lower end of the second limiting surface 220. In this way, it is possible not only to fully open the dispenser box 200 automatically and smoothly, but also to ensure the overall stability of the opened dispenser box 200.

[0065] The detergent box 100 may include the base and the upper cover. The upper cover is detachably disposed at the base. The accommodation cavity is defined between the upper cover and the base. In this way, the manufacturing of the detergent box 100 is facilitated. Moreover, it is convenient to maintain and replace the components disposed in the detergent box 100. The upper cover is located at the top of the detergent box 100, and the base is located at the bottom of the detergent box 100. The upper cover and the base are assembled together to form the detergent box 100. The upper cover and the base may be mounted by snaps or screws. The dispenser box 200 is adapted to be pushed into the accommodation cavity of the detergent box 100 from the front side.

[0066] In some other optional embodiments, the dispenser box 200 is disposed in the detergent box 100 in such a manner that the dispenser box 200 is movable in the front-rear direction. The dispenser box 200 is movable between an open position and a closed position. A button may be provided at a front surface of the dispenser box 200 to facilitate the user's operation. For example, the dispenser box 200 has an open state and a closed state. When the dispenser box 200 is located at the open position, the dispenser box 200 is in the open position. At this time, the dispenser box 200 at least partially extends from the front surface of the detergent box 100, allowing the detergent such as washing powder, laundry detergent, or softener to be poured into the dispenser box 200. When the dispenser box 200 is in the closed position, the dispenser box 200 is in the closed state. At this time, the front surface of the dispenser box 200 is preferably and substantially flush with a front surface of the detergent box 100, thereby ensuring an aesthetically pleasing appearance of the laundry treatment device such as a front load washing machine.

[0067] The dispenser box 200 may include a plurality of containing grooves for containing different detergents. The plurality of containing grooves is arranged at intervals.

The button and the locking member may be disposed at the dispenser box panel. For example, the button is disposed at a front surface of the dispenser box panel, and the locking member is disposed at a rear surface of the dispenser box panel. Therefore, the washing machine has a more aesthetically pleasing appearance.

[0071] When the dispenser box 200 is fully engaged in the detergent box 100, the dispenser box cover and the dispenser box body are located between the detergent box cover and the detergent box body. Moreover, the dispenser box panel may be flush with a front surface of the body and tightly seal a front surface of a mounting cavity, thereby providing a washing machine with neat and attractive appearance.

[0072] During operating of the liquid storage box assembly 1 according to the above embodiments of the present disclosure, when the detergent needs to be dispensed into the dispenser box 200, the dispenser box 200 is in the closed position. At this time, the dispenser box 200 needs to be switched from the closed position to the open position. After the button is pressed, the locking member is unlocked. As a result, the dispenser box 200 moves from the closed position to the open position. When the dispenser box 200 moves to the open position, the user may pour the detergent and the like into the dispenser box 200. After pouring of the detergent into the dispenser box 200 is completed, when it is necessary to close the dispenser box 200, the dispenser box 200 is pushed from front to back to move backwards. As the dispenser box 200 moves to the closed position, the locking member is locked. As a result, the dispenser box 200 is in the closed state.

[0073] According to some other embodiments of the present disclosure, the liquid storage box assembly 1 may include a box body 10 and a detection device 300. The detection device 300 is configured to detect the presence or absence of the detergent. The liquid storage box assembly 1 is disposed in the washing machine.
