Description

CROSS-REFERENCE TO RELATED APPLICATIONS



[0001] This application claims priorities to and benefits of Chinese Patent Application Nos. 202210730928.X and 202221614534.X, filed with China National Intellectual Property Administration on June 24, 2022, the entire contents of which are incorporated herein by reference.

FIELD



[0002] The present disclosure relates to the field of washing technologies, and more particularly, to a dispenser, a detergent drawer assembly, and a clothes treatment apparatus.

BACKGROUND



[0003] A clothes treatment apparatus, such as a washing machine, is a commonly used household cleaning apparatus. In a process of washing to-be-washed clothes with the clothes treatment apparatus, generated washing water often contains micro-particles that are difficult to decompose in nature. Directly discharging the washing water will lead to the micro-particles flowing into nature and causing environmental pollution. Some current clothes treatment apparatuses are equipped with filters at water outlets for discharging washing water, which are configured to filter out at least some of the micro-particles in the washing water. However, the micro-particles accumulated in the filter will be more and more uneven distribution over time. The uneven accumulation of these micro-particles inevitably hinders the efficiency of circulating water filtration, thereby reducing the service life of the filter and requiring users to frequently check or replace the filter.

SUMMARY



[0004] Embodiments of the present disclosure provide a dispenser, a detergent drawer assembly, and a clothes treatment apparatus for solving at least the problem of how to filter washing water to reduce pollution.

[0005] The dispenser of the embodiments of the present disclosure comprises a dispensing area and a filtering area located at a side of the dispensing area. The filtering area is provided with a water inlet area for to-be-filtered washing water at an end of the filtering area. A part of a bottom of the filtering area close to the water inlet area is higher than a part of the bottom of the filtering area away from the water inlet area.

[0006] In some embodiments, the bottom of the filtering area is inclined downwardly in a direction from close to the water inlet area to away from the water inlet area.

[0007] In some embodiments, a bottom of the dispensing area is inclined downwardly in a direction from the dispensing area to the filtering area.

[0008] In some embodiments, the dispensing area has a sealed bottom. The bottom of the filtering area has a through hole. A baffle is provided between the dispensing area and the filtering area. The baffle has a communication hole. The dispensing area is in communication with the filtering area through the communication hole.

[0009] The detergent drawer assembly of the embodiments of the present disclosure comprises a detergent drawer having a cavity, the dispenser as described in any one of the above embodiments, and a filter. The detergent drawer has a water inlet, a water outlet, and a circulating water inlet at a peripheral wall of the detergent drawer, and each of the water inlet, the water outlet, and the circulating water inlet is in communication with the cavity. The dispenser is mounted and drawable in the cavity. The dispensing area corresponds to and is in communication with the water inlet, and the filtering area is in communication with the circulating water inlet and the water outlet. The filter is mounted in the filtering area and configured to filter circulating water flowing into the filtering area from the circulating water inlet.

[0010] In some embodiments, the detergent drawer has an opening through which the dispenser is drawable. The circulating water inlet is formed at a sidewall of the detergent drawer opposite to the opening.

[0011] In some embodiments, the peripheral wall of the detergent drawer further has an anti-blocking opening in communication with the cavity. The anti-blocking opening is higher than the circulating water inlet and is configured to allow the circulating water to flow into the filtering area.

[0012] In some embodiments, the water outlet comprises at least two sub-water outlets. A flow detection device is disposed on at least one of the at least two sub-water outlets.

[0013] In some embodiments, the filter comprises a flexible filter bag and a fixed nozzle provided at an inlet of the filter bag. The filter is detachably mounted in the filtering area by the fixed nozzle.

[0014] In some embodiments, the fixed nozzle is engaged with the circulating water inlet. The circulating water flows into the filter bag through the fixed nozzle. The filter bag has a plurality of water outlet holes. The plurality of water outlet holes is configured to allow filtered circulating water to flow to the water outlet through the plurality of water outlet holes.

[0015] The clothes treatment apparatus of the embodiments of the present disclosure comprises a housing, a tub assembly located within the housing, the detergent drawer assembly as described in any one of the above embodiments, and a circulating pump located within the housing. The tub assembly has a washing cavity. The water outlet of the detergent drawer assembly is in communication with the washing cavity. The circulating pump is connected to both the washing cavity and the circulating water inlet.

[0016] In the dispenser, the detergent drawer assembly, and the clothes treatment apparatus according to the embodiment of the present disclosure, since the part of the bottom of the filtering area close to the water inlet area is higher than the part of the bottom of the filtering area away from the water inlet area, to-be-filtered washing water flowing into the filtering area from the water inlet area can flow from high to low along the bottom of the filtering area to the part of the filtering area away from the water inlet area. The washing water then smoothly flows to the water outlet, and drives the accumulated micro-particles to accumulate in a direction away from the water inlet area, thereby smoothly realizing circulation flow and enhancing the service life of the filter. Therefore, the filter can collect more micro-particles, and reduce the number of times the user has to clean or replace the filter.

[0017] Additional aspects and advantages of the present disclosure will be given at least in part in the following description, will become apparent at least in part from the following description, or can be learned from practicing of the present disclosure.

In addition, terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features associated with "first" and "second" may explicitly or implicitly comprise at least one feature. In the description of the present disclosure, "a plurality of" means at least two, unless otherwise specifically defined.

[0021] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, terms "install", "connect", and "connect to" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; mechanical connection, electrical connection, or in communication with each other; direct connection or indirect connection through an intermediate; or internal communication of two components or the interaction relationship between two components.

[0022] Referring to FIG. 1, an embodiment of the present disclosure provides a dispenser 30. The dispenser 30 comprises a dispensing area 31 and a filtering area 32. The filtering area 32 is located at a side 312 of the dispensing area 31. The filtering area 32 is provided with a water inlet area 320 for to-be-filtered washing water at an end 324 of the filtering area 32. A part of a bottom 322 of the filtering area 32 close to the water inlet area 320 is higher than a part of the bottom 322 of the filtering area 32 away from the water inlet area 320.

[0023] In the dispenser 30 according to the embodiments of the present disclosure, since the part of the bottom 322 of the filtering area 32 close to the water inlet area 320 is higher than the part of the bottom 322 of the filtering area 32 away from the water inlet area 320, to-be-filtered washing water flowing into the filtering area 32 from the water inlet area 320 can flow from high to low along the bottom 322 of the filtering area 32 to the part of the bottom 322 of the filtering area 32 away from the water inlet area 320. Then, the washing water smoothly flows to the water outlet 212 (shown in FIG. 4), and drive the accumulated micro-particles to accumulate in a direction away from the water inlet area 320, thereby smoothly realizing circulation flow and enhancing the service life of the filter 10 (shown in FIG. 4). Therefore, the filter 10 can collect more micro-particles and reduce the number of times the user has to clean or replace the filter 10.

[0024] The present disclosure is described in further detail below in conjunction with the accompanying drawings.

[0025] Referring to FIG. 2 to FIG. 4, the present disclosure provides a detergent drawer assembly 100. The detergent drawer assembly 100 comprises a detergent drawer 20, the dispenser 30, and the filter 10. The filter 10 is detachably mounted at the dispenser 30. The dispenser 30 and the filter 10 are drawably disposed in the detergent drawer 20.

[0026] Referring to FIG. 4 to FIG. 6, in an exemplary embodiment of the present disclosure, the detergent drawer 20 has a cavity 21. The detergent drawer 20 has a water inlet 211, a water outlet 212, and a circulating water inlet 213 at a peripheral wall of the detergent drawer 20. Each of the water inlet 211, the water outlet 212, and the circulating water inlet 213 is in communication with the cavity 21. That is, the water inlet 211 is in communication with the cavity 21, the water outlet 212 is in communication with the cavity 21, and the circulating water inlet 213 is in communication with the cavity 21.

[0027] Referring to FIG. 4, in some embodiments, the peripheral wall of the detergent drawer 20 comprises a sidewall 201, a top 202, and a bottom 203. In an embodiment, the water inlet 211 is formed at the top 202. The water outlet 212 is formed at the bottom 203. The circulating water inlet 213 is formed at the sidewall 201.

[0028] Referring to FIG. 5, in some embodiments, the detergent drawer 20 has an opening 214 through which the dispenser 30 is drawable. The dispenser 30 is inserted into or pulled out from the cavity 21 through the opening 214. Referring to FIG. 5 and FIG. 6, when detergent needs to be added, the dispenser 30 is pulled out from the cavity 21 to allow the dispenser 30 to be at least partially exposed outside the housing 200, thereby facilitating the user to put the detergent into the dispenser 30.

[0029] Referring to FIG. 4, in an embodiment, the detergent drawer 20 further comprises a water inlet tube 231. The top 202 comprises a water inlet chamber 232 in communication with the water inlet 211. The water inlet tube 231 is connected to an external water source. After the user puts the detergent into the dispenser 30, the dispenser 30 is pushed back into the cavity 21, and water is injected into the water inlet tube 231 from the external water source. The injected water flows to the water inlet 211 after passing through the water inlet chamber 232, and flows to the dispenser 30 in the cavity 21 from the water inlet 211, to flush the detergent in the dispenser 30 to the water outlet 212. The detergent-containing water flows into an external device from the water outlet 212, and the external device may be washed with the detergent-containing water. The detergent-containing water in the external device can reflow into the detergent drawer assembly 100 from the circulating water inlet 213 to form circulating water.

[0030] Referring to FIG. 4, in some embodiments, one water outlet 212 is provided, and the water outlet 212 is formed at the bottom 203 of the detergent drawer 20 and close to the opening 214. In an exemplary embodiment of the present disclosure, the water outlet 212 is located at a lowest position of the bottom 203 of the detergent drawer 20. Therefore, both a cleaning water with the rinsed detergent after passing through the water inlet 211 or the circulating water after passing through the filter 10 can quickly flow to the water outlet 212 at the lowest position, thereby improving the circulation efficiency and further improving the washing efficiency.

[0031] In other embodiments, the water outlet 212 comprises at least two sub-water outlets. For example, the water outlet 212 comprises two sub-water outlets, i.e., a main water outlet and an auxiliary water outlet (not shown in the figures). The main water outlet is the same as the water outlet 212 in the above embodiments (shown in FIG. 4), and may be formed at the bottom 203 of the detergent drawer 20 and close to the opening 214. The main water outlet may be located at the lowest position of the bottom 203 of the detergent drawer 20. Therefore, both the cleaning water with the rinsed detergent after passing through the water inlet 211 or the circulating water after passing through the filter 10 can quickly flow to the main water outlet at the lowest position, thereby improving the circulation efficiency and further improving the washing efficiency. The auxiliary water outlet may further be formed at the bottom 203 of the detergent drawer 20 and close to the filtering area 32. A flow detection device is mounted at the auxiliary water outlet, and the auxiliary water outlet is in communication with the main water outlet via a tube located outside the detergent drawer 20. The flow detection device is configured to monitor a flow rate of water falling from the filtering area 32, thereby monitoring whether the filtering area 32 is blocked. Once the blocking occurs, the flow detection device is configured to feedback to the user to remind the user to clean impurities in the filtering area 32 in time.

[0032] The dispenser 30 is drawably mounted in the cavity 21. When the dispenser 30 is mounted in the cavity 21, a channel 215 is formed between the dispenser 30 and the bottom 203 of the cavity 21. The circulating water in the dispenser 30 can flow into the channel 215 and then flow to the water outlet 212 through the channel 215.

[0033] Referring to FIG. 5, in some embodiments, each of a sidewall 205 and a sidewall 206 at two sides of the opening 214 of the detergent drawer 20 is provided with a sliding rail 26. Each of a sidewall 301 and a sidewall 302 of the dispenser 30 is provided with a sliding block 36. Each of the sliding rails 26 cooperates with a corresponding one of the sliding blocks 36 to enable the dispenser 30 to slide relative to the detergent drawer 20 in the cavity 21, to facilitate drawing of the dispenser 30. In other embodiments, each of the sidewall 205 and the sidewall 206 at the two sides of the opening 214 of the detergent drawer 20 is provided with the sliding block, and each of the sidewall 301 and the sidewall 302 of the dispenser 30 is provided with the sliding rail, which is not limited herein.

[0034] In some embodiments, the dispenser 30 comprises the dispensing area 31 and the filtering area 32 located at the side 312 of the dispensing area 31. A top side of the dispensing area 31 is open to receive the detergent, and a top side of the filtering area 32 is open to receive the filter 10. For example, in the embodiment shown in FIG. 5, an end of the dispensing area 31 facing the opening 214 is a front end 311, and the side at which the filtering area 32 is located is a rear end 312. The dispensing area 31 is adjacent to the filtering area 32. When the dispenser 30 is mounted in the cavity 21, the dispensing area 31 corresponds to and is in communication with the water inlet 211, and the filtering area 32 is in communication with the circulating water inlet 213 and the water outlet 212.

[0035] In an embodiment, the dispenser 30 further comprises a baffle 35 provided between the filtering area 32 and the dispensing area 31. The baffle 35 is configured to separate the filtering area 32 from the dispensing area 31. When the dispenser 30 is located in the cavity 21, the dispensing area 31 corresponds to and is in communication with the water inlet 211, and the filtering area 32 is in communication with the circulating water inlet 213 and the water outlet 212.

[0036] Referring to FIG. 4 and FIG. 6, the filter 10 is mounted in the filtering area 32, and is configured to filter the circulating water flowing into the filtering area 32 from the circulating water inlet 213. Water flows into the dispensing area 31 from the water inlet 211 and rinses the detergent in the dispensing area 31 to the water outlet 212. After the detergent-containing water flows into a washing cavity 2103 (shown in FIG. 10) to clean a to-be-cleaned object, the generated wastewater containing a large number of micro-particles flows into the filtering area 32 from the circulating water inlet 213, is filtered by the filter 10, and then flows back to the washing cavity 2103 through the water outlet 212. In this way, it can not only realize the recycling of water but also filter most of the lint and micro-particles in the water. In this way, a large number of micro-particles are prevented from being directly discharged into the environment along with the washing water, thereby reducing environmental pollution. The circulating water circulates from the circulating water inlet 213 into the detergent drawer 20, and exits from the water outlet 212 after being filtered by the filter 10. In this way, after multiple filtrations, the micro-particles in the circulating water are successively intercepted by the filter 10, allowing the micro-particles in the circulating water leaving the water outlet 212 after each filtration to be reduced. Therefore, the micro-particles in the circulating water can be effectively filtered to reduce the pollution of the micro-particles to the environment.

[0037] In an exemplary embodiment of the present disclosure, referring to FIG. 7, the filter 10 comprises a flexible filter bag 11 and a fixed nozzle 12. The flexible filter bag 11 has a water inlet 111 and a plurality of water outlet holes 112. The fixed nozzle 12 is disposed at the water inlet 111, and is configured to allow the circulating water to pass through to flow into the filter bag 11 from the water inlet 111. The plurality of water outlet hole 112 of the flexible filter bag 11 is configured to block at least part of the micro-particles in the circulating water and allow the filtered circulating water to pass therethrough.

[0038] The circulating water is water that flows into filter 10 multiple times. For example, the filter 10 is connected to an external element, and the circulating water circulates between the filter 10 and the washing cavity 2103 (shown in FIG. 10). The circulating water is filtered once each time it flows through the filter 10. As the number of filtrations increases, a microparticle content of the circulating water decreases. Non-circulating water may also be filtered by the filter 10, which is not limited herein.

[0039] The filter 10 in the embodiment shown in FIG. 7 and FIG. 8 only schematically shows a number, shape, and size of the water outlet holes 112. In other embodiments, the number and size of the water outlet holes 112 may be adjusted based on filtration requirements, which are not limited herein. For example, the number of the water outlet holes 112 may be 80 mesh, 100 mesh, 120 mesh, or the like, which is not limited herein. As shown in FIG. 7, in an embodiment, the water outlet holes 112 are distributed throughout the flexible filter bag 11, allowing the water outlet efficiency to be high and allowing water to flow out in multiple directions. As shown in FIG. 8, in another embodiment, the water outlet holes 112 are formed in a partial area of the flexible filter bag 11, to limit a position of the water outlet and an impact direction of the water flow.

[0040] The micro-particles comprise particles with smaller diameters such as microplastics, for example, plastic particles with a diameter smaller than 5 mm. The microparticles are difficult to decompose in nature, and are easy to enter a natural water cycle due to their small size. Therefore, discharging circulating water containing micro-particles into nature will bring greater pollution. The filter 10 of the embodiments of the present disclosure can filter the micro-particles in the circulating water to reduce environmental pollution caused by the micro-particles.

[0041] When a rigid filter mesh structure is configured to filter micro-particles in a fluid, the micro-particles are easy to accumulate at a mesh of the filter, resulting in low filtration efficiency of the filter mesh structure. The flexible filter bag 11 is a flexible structure. When the circulating water flows, the flexible filter bag 11 deforms, and a position of the water outlet holes 112 relative to the external element (the detergent drawer 20) is changed. Therefore, the micro-particles are not easy to accumulate at the fixed position of the external element, and allow the water to flow out more smoothly.

[0042] Referring to FIG. 7 and 8, in some embodiments, the fixed nozzle 12 comprises a water inlet nozzle 121 and a fixing plate 122. The water inlet nozzle 121 is mounted at the water inlet 111 and protrudes out of the flexible filter bag 11. The fixing plate 122 is arranged around the water inlet nozzle 121, and is configured to be connected with the external element (i.e., the detergent drawer 20).

[0043] Referring to FIG. 5 to FIG. 7, the circulating water inlet 213 is formed at the sidewall 201 of the detergent drawer 20 opposite to the opening 214 and protrudes out of the cavity 21. Referring to FIG. 4, FIG. 7, and FIG. 8, in an example, the water inlet nozzle 121 of the fixed nozzle 12 extends into the circulating water inlet 213 to allow the water inlet nozzle 121 to be in communication with the circulating water inlet 213. The circulating water flows into the flexible filter bag 11 through the water inlet nozzle 121 and flows out from the water outlet holes 112. In another example, the water inlet nozzle 121 of the fixed nozzle 12 does not extend into the circulating water inlet 213, and the fixed nozzle 12 and the circulating water inlet 213 only need to be engaged in alignment with each other to form a closed passage through which the water can flow. Therefore, the water inlet nozzle 121 can be in communication with the circulating water inlet 213, and the circulating water flows into the flexible filter bag 11 through the water inlet nozzle 121 and flows out from the water outlet holes 112. In another example, the water inlet nozzle 121 of the fixed nozzle 12 does not extend into the circulating water inlet 213, and is spaced apart from and opposite to the circulating water inlet 213. A pipeline may be provided for communication between the water inlet nozzle 121 and the circulating water inlet 213. Therefore, the circulating water flows into the flexible filter bag 11 through the water inlet nozzle 121 and flows out from the water outlet holes 112. In some embodiments, the filtering area 32 comprises a through hole 321 in communication with the channel 215. The circulating water flowing from the water outlet holes 112 flows into the channel 215 through the through hole 321, to flow into the water outlet 212 from the bottom 203 of the cavity 21.

[0044] Referring to FIG. 5 to FIG. 7, in some embodiments, the sidewall 324 of the filtering area 32 has a mounting hole 323 corresponding to the circulating water inlet 213. The fixing plate 122 of the fixed nozzle 12 is detachably mounted in the mounting hole 323, to allow the filter 10 to be detachably mounted in the filtering area 32. Thus, the filter 10 containing the micro-particles can be easily removed. For example, when the number of the micro-particles in the flexible filter bag 11 is large, the filter 10 is detached from the filtering area 32. The micro-particles in the filter 10 are removed and then remounted in the filtering area 32, or a new filter 10 is replaced and mounted in the filtering area 32, to remove the micro-particles in time and prevent the micro-particles from blocking the water outlet holes 112 and hindering the circulation of the circulating water.

[0045] In an embodiment, a sidewall 3231 of the mounting hole 323 is provided with an engagement groove 3232. The fixing plate 122 can be inserted into or pulled out from the engagement groove 3232, to allow the fixing plate 122 to be detachably mounted in the mounting hole 323. An engagement structure of the fixing plate 122 and the engagement groove 3232 is simple to achieve a convenient disassembling operation.

[0046] In another embodiment, a sidewall 1221 of the fixing plate 122 is provided with an engagement groove (not shown in the figures). The sidewall 3231 of the mounting hole 323 can be directly inserted into or pulled out from the engagement groove, to allow the fixing plate 122 to be detachably mounted in the mounting hole 323. In another exemplary embodiment of the present disclosure, the sidewall 3231 of the mounting hole 323 is provided with a protrusion (not shown in the figures), and a thickness of the protrusion is smaller than a thickness of the sidewall of the mounting hole 323. The protrusion can be inserted into or pulled out from the engagement groove, to allow the fixing plate 122 to be detachably mounted in the mounting hole 323.

[0047] In another embodiment, the sidewall 3231 of the mounting hole 323 has a first thread (not shown in the figures), and the fixing plate 122 has a second thread (not shown in the figures). The first thread is engaged with the second thread to allow the fixing plate 122 to be detachably mounted in the mounting hole 323. The threaded engagement between the fixing plate 122 and the mounting hole 323 can make the connection between the fixing plate 122 and the mounting hole 323 more stable.

[0048] Referring to FIG. 5 to FIG. 7, in some embodiments, the filter bag 11 is laid flat at the bottom 322 of the filtering area 32 when the circulating water does not flow into the filter bag 11. The filter bag 11 is filled with water and bulges to fill the filtering area 32 when the circulating water flows into the filter bag 11 through the circulating water inlet 213 and the water inlet nozzle 121. As the circulating water continues to flow into the filter bag 11, a water pressure is formed in the bulged filter bag 11. Even if part of the water outlet holes 112 are blocked, the circulating water can be pressed out from the blocked water outlet holes 112 under the action of the water pressure, allowing the circulating water to smoothly flow out of the filter bag 11.

[0049] Referring to FIG. 3 and FIG. 4, in some embodiments, the peripheral wall of the detergent drawer 20 further has an anti-blocking opening 204, and the anti-blocking opening 204 corresponds to and is in communication with the filtering area 32. The anti-blocking opening 204 is located higher than the circulating water inlet 213. The anti-blocking opening 204 is configured to allow the circulating water to flow into the filtering area 32, when the micro-particles in the filter bag 11 are overloaded and the circulating water cannot flow into the filter bag 11 from the circulating water inlet 213.

[0050] Referring to FIG. 4 and FIG. 5, in some embodiments, in a direction X1 from the dispensing area 31 to the filtering area 32, a part of the bottom 313 of the dispensing area 31 close to the water inlet 211 is higher than a part of the bottom 313 of the dispensing area 31 away from the water inlet 211. In this way, it is possible to facilitate the detergent injected at the part close to the water inlet 211 to flow from high to low to the part away from the water inlet 211. In one embodiment, a drain outlet 3131 is formed at the part of the bottom 313 away from the water inlet 211, and is in communication with the channel 215. The detergent injected from the water inlet 211 can flow into the drain outlet 3131 from high to low, flow into the channel 215 from the drain outlet 3131, and exit from the water outlet 212.

[0051] In another embodiment, the bottom 313 of the dispensing area 31 is sealed, and the dispensing area 31 is in communication with the water outlet 212 through the through hole 321 of the bottom 322 of the filtering area 32. The dispensing area 31 is in communication with the filtering area 32. For example, referring to FIG. 5, the dispenser 30 further comprises the baffle 35 arranged between the filtering area 32 and the dispensing area 31, and the baffle 35 has a communication hole 351. The part of the bottom 313 of the dispensing area 31 close to the water inlet 211 is higher than a part of the bottom 313 of the dispensing area 31 close to the baffle 35. In this way, the detergent injected from the water inlet 211 can flow from high to low to the communication hole 351 and reach the filtering area 32 after passing through the communication hole 351. Referring to FIG. 4, the circulating water of the filter 10 flows into the channel 215 through the through hole 321 and exits through the water outlet 212, thereby increasing the flow rate of the water flowing out of the dispensing area 31.

[0052] When there is no circulating water in the detergent drawer 20, the detergent in the channel 215 can exit from the water outlet 212, which is not limited herein.

[0053] In some embodiments, the bottom 313 of the dispensing area 31 is an inclined plane. A part of the inclined plane close to the water inlet 211 is at a high position, and a part of the inclined plane away from the water inlet 211 is at a low position. A surface of the inclined plane may be a flat surface or a curved surface, which is not limited herein.

[0054] For example, in the embodiment of FIG. 4 and FIG. 5, a side of the dispensing area 31 facing the opening 214 is the front end 311, and the side at which the filtering area 32 is located is the rear end 312. The water inlet 211 is formed at the front end 311. In an embodiment, a direction from the front end 311 to the rear end 312 or a direction from the rear end 312 to the front end 311 is a length direction (X1/X2) of the dispenser 30. Accordingly, the two sides of the opening 214 form a width direction (Y1/Y2) of the dispenser 30. The bottom 313 of the dispensing area 31 is inclined in the length direction (X1/X2). In another embodiment, the direction from the front end 311 to the rear end 312 or the direction from the rear end 312 to the front end 311 is the width direction of the dispenser 30. Accordingly, the two sides of the opening 214 form the length direction of the dispenser 30. The bottom 313 of the dispensing area 31 is inclined in the width direction, which is not limited herein.

[0055] Referring to FIG. 5 and FIG. 6, in some embodiments, when the dispenser 30 is located in the cavity 21, a part of the bottom 322 of the filtering area 32 close to the circulating water inlet 213 (or the mounting hole 323, as below) is higher than a part of the bottom 322 of the filtering area 32 away from the circulating water inlet 213. Since the filter bag 11 has flexibility, a part of the filter bag 11 disposed in the filtering area 32 close to the circulating water inlet 213 is higher than a part of the filter bag 11 away from the circulating water inlet 213. In this way, it is convenient for the circulating water to flow from high to low to a position away from the water inlet 211, and the existing micro-particles in the filter 10 are rinsed and driven to gather at a position away from the circulating water inlet 213, to avoid accumulation near the circulating water inlet 213, thereby improving a space utilization ratio of the filter 10. Referring to FIG. 5, in an embodiment, the through hole 321 in communication with the channel 215 is formed at the part of the bottom 322 of the filtering area 32 away from the circulating water inlet 213. The circulating water in the filter bag 11 flows from high to low to the through hole 321, and flows into the channel 215 from the through hole 321.

[0056] In some embodiments, the bottom 322 of the filtering area 32 is an inclined plane. A part of the inclined plane close to the circulating water inlet 213 is at a high position, and a part of the inclined plane away from the circulating water inlet 213 is at a low position. A surface of the inclined plane may be a flat surface or a curved surface, which is not limited herein. In an embodiment, the bottom 322 of the filtering area 32 has the through hole 321 only at the lower part of the bottom 322. In another embodiment, a plurality of through holes 321 are formed at the bottom of the filtering area 32, and through holes 321 are formed at both the upper and lower parts of the bottom to increase the flow rate of the circulating water flowing into the channel 215.

[0057] For example, in the embodiment of FIG. 4 and FIG. 6, the side of the dispensing area 31 facing the opening 214 is the front end 311, and the side of the filtering area 32 is the rear end 312. The water inlet 211 is formed at the front end 311. In an embodiment, the direction from the front end 311 to the rear end 312 or the direction from the rear end 312 to the front end 311 is the length direction (X1/X2) of the dispenser 30. Accordingly, the two sides of the opening 214 form the width direction (Y1/Y2) of the dispenser 30. The bottom 322 of the filtering area 32 is inclined in the width direction (Y1/Y2). In another embodiment, the direction from the front end 311 to the rear end 312 or the direction from the rear end 312 to the front end 311 is the width direction of the dispenser 30. Accordingly, the two sides of the opening 214 form the length direction of the dispenser 30. The bottom 322 of the filtering area 32 is inclined in the length direction, which is not limited herein.

[0058] Referring to FIG. 9 and FIG. 10, the embodiments of the present disclosure provide a clothes treatment apparatus 1000. The clothes treatment apparatus 1000 comprises a housing 200, a tub assembly 210 located in the housing 200, a circulating pump 220 located in the housing 200, and a detergent drawer assembly 100 according to any one of the embodiments of the present disclosure. Referring to FIG. 4 and FIG. 8, the detergent drawer assembly 100 comprises the filter 10 of the embodiments of the present disclosure. The housing 200 has a draw-out port 230, and the detergent drawer assembly 100 is disposed in the housing 200 and positioned at the draw-out port 230. The tub assembly 210 comprises an outer tub 2101 and an inner tub 2102 rotatably disposed in the outer tub 2101. The inner tub 2102 has a washing cavity 2103, and a water passage cavity 2104 is formed between the outer tub 2101 and the inner tub 2102. The water passage cavity 2104 is respectively in communication with the washing cavity 2103 and the circulating pump 220, to allow the circulating water in the washing cavity 2103 to be introduced into the circulating pump 220. The water outlet 212 is in communication with the washing cavity 2103, and the circulating pump 220 is connected to both the water passage cavity 2104 and the circulating water inlet 213. In addition, the clothes treatment apparatus 1000 may further comprise a circulation tube 2201. One end of the circulation tube 2201 is in communication with the circulating water inlet 213, and another end of the circulation tube 2201 is in communication with the circulating pump 220, to allow the circulating pump 220 to be in communication with the circulating water inlet 213. In this way, the circulating pump 220 can supply the circulating water into the circulating water inlet 213 through the circulation tube 2201.

[0059] The clothes treatment apparatus 1000 can be configured to wash to-be-washed objects, such as clothes and shoes. For example, the clothes treatment apparatus 1000 is a washing machine for washing clothes. Referring to FIG. 5 and FIG. 9, the user loads the to-be-washed objects into the washing cavity 2103 of the inner tub 2102 before washing, and then puts the detergent into the dispenser 30. Water is injected into the detergent drawer assembly 100 through the water inlet tube 231, and the water flowing into the detergent drawer assembly 100 is mixed with the detergent and then flows into the washing cavity 2103 through the water outlet 212. During washing, the inner tub 2102 rotates relative to the outer tub 2101 to drive the to-be-washed objects and detergent-containing washing water in the washing cavity 2103 to rotate for washing. In an embodiment, the washing water in the inner tub 2102 flows into the water passage cavity 2104, and the outer tub 2101 discharges the washing water into the circulating pump 220. The circulating pump 220 pumps the washing water in the water passage cavity 2104 to the circulating water inlet 213, to allow the washing water to reflow into the detergent drawer assembly 100. Thus, the washing water circulates among the detergent drawer assembly 100, the tub assembly 210, and the circulating pump 220 to form the circulating water.

[0060] During the circulation of the circulating water, the micro-particles in the circulating water are filtered by the filter 10 to prevent discharge of the circulating water containing the micro-particles to pollute the environment. Some impurities with a size larger than the size of the micro-particles, such as lint, hairballs, and paper scraps, can also be filtered by the filter 10 to avoid impurities adhering to the washed objects, for example, to avoid paper scraps adhering to the surface of the washed clothes.

[0061] In summary, in the detergent drawer assembly 100 and the clothes treatment apparatus 1000 of the embodiments of the present disclosure, the flexible filter bag 11 of the filter 10 can filter the micro-particles in the circulating water, and the flexible filter bag 11 can deform to a certain extent with the flow of the circulating water, thereby changing the position of the water outlet holes 112 relative to the external element (i.e., the detergent drawer 20). Therefore, the micro-particles are not easy to accumulate in a fixed position of the external element (i.e., the detergent drawer 20), and the water can flow out more smoothly.
