The present application will now be described in further detail with reference to the accompanying drawings and specific examples.

Referring to fig. 1 to 4, the present embodiment provides a filter device 100, the filter device 100 includes a mounting plate assembly 110 and a cover case 120, the mounting plate assembly 110 and an inner circumferential surface of a washing drum 200 of a laundry treatment apparatus together define a discharge passage 110a, and the mounting plate assembly 110 is formed with a lint outlet 110b communicating with the discharge passage 110 a. The cover shell 120 is disposed on one side of the mounting plate assembly 110 far from the inner circumferential surface of the washing tub 200, the cover shell 120 and the mounting plate assembly 110 together define a lint cavity 120a, the lint cavity 120a has a water inlet 120aa and a water outlet 120ab, the lint outlet 110b is communicated with the lint cavity 120a, and the lint outlet 110b is higher than the water inlet 120aa and the water outlet 120 ab. Specifically, both water inlet 120aa and water outlet 120ab can communicate with washing drum 200.

Referring to fig. 1, the laundry treating apparatus includes a washing drum 200, the filtering apparatus 100 according to any embodiment of the present disclosure, and a mounting plate assembly 110 disposed on an inner circumferential surface of the washing drum 200.

The type of the laundry treating apparatus is not limited, and for example, the laundry treating apparatus includes, but is not limited to, a washing machine, and the washing machine may include a pulsator 300 rotatably disposed at the bottom of the washing tub 200. In washing, the laundry may be washed by rotating the pulsator 300 to agitate the laundry and the water current. During dehydration, the pulsator 300 and the washing tub 200 may be rotated in synchronization to dry the moisture on the laundry. In the embodiment of the present application, a laundry processing apparatus is described as an example of a washing machine, and it should be understood that this does not limit the embodiment of the present application.

According to the filtering device 100 provided by the embodiment of the application, during washing, water flow carrying the lint in the washing drum 200 enters the lint cavity 120a through the water inlet 120aa, the filtered water flow flows back to the washing drum 200 through the water outlet 120ab, and the filtered lint is temporarily left in the lint cavity 120 a. Since the lint outlet 110b is higher than the water outlet 120ab and the water inlet 120aa, when washing, the flow rate of the water in the washing drum 200 can be limited by controlling the rotation speed of the pulsator 300 and/or the washing drum 200, so as to limit the climbing height of the water, which is lower than the height of the lint outlet 110b, and therefore, the water cannot flow to the lint outlet 110b, and the lint cannot be flushed out of the lint chamber 120a through the lint outlet 110 b. When the thread scraps need to be discharged, at least one of the pulsator 300 and/or the washing tub 200 rotates at a predetermined rotation speed, and the water in the washing tub 200 enters the thread scraps cavity 120a from the water inlet 120aa, and the water impacts the thread scraps upward to impact the thread scraps through the thread scraps outlet 110b into the discharge passage 110a, and discharge the thread scraps out of the washing tub 200 through the discharge passage 110 a.

It is understood that, in the thread-thrum discharging process, the set rotation speed of the pulsator 300 and/or the washing tub 200 may be determined according to the water level in the washing tub 200, and it is only necessary that the set rotation speed of the pulsator 300 and/or the washing tub 200 enables the water current to impact the thread-thrums to flow out of the thread-thrum outlet 110 b.

In one embodiment, the filtering device 100 includes a filter net covering the water outlet 120 ab. Thus, the water flow from the water inlet 120aa can flow back into the washing tub 200 through the mesh of the filter net, and lint cannot pass through the mesh of the filter net to be temporarily retained in the lint chamber 120 a.

The specific location of the water outlet 120ab is not limited, and for example, in one embodiment, referring to fig. 1 and 5, the water outlet 120ab is formed on the side of the cover shell 120 facing away from the mounting plate assembly 110. The side of the cover shell 120 facing away from the mounting plate assembly 110 is generally larger in area and faces the central region of the washing drum 200, such that the total area of the water outlet 120ab can be larger and faces the central region of the washing drum 200, facilitating a large, rapid backflow of filtered water into the washing drum 200.

The specific form of the water outlet 120ab is not limited, and for example, in an embodiment, referring to fig. 5, the water outlet 120ab includes a plurality of sub water outlets, and the plurality of sub water outlets are arranged in a matrix. Like this, the area of single sub-delivery port is less, and a plurality of sub-delivery ports constitute delivery port 120ab jointly, can guarantee the total area of delivery port 120ab, can guarantee again that the position that constitutes sub-delivery port can provide the support for the filter screen, guarantees structural strength.

In one embodiment, referring to fig. 3 and 4, the bottom side of the lint cavity 120a is open to form the water inlet 120 aa. That is, the water flow may enter the lint chamber 120a through the bottom side of the lint chamber 120 a. For convenience of explanation, the water inlet port 120aa at the bottom side of the lint cavity 120a is defined as a first water inlet port 120aa ', and thus, the water flow at the lower position of the washing tub 200 can enter the lint cavity 120a through the first water inlet port 120 aa'. In the washing, the pulsator 300 drives the water at a lower position to move, so that the water at the lower position can smoothly enter the thread-waste chamber 120a, thereby collecting thread waste more comprehensively.

In one embodiment, referring to fig. 4 and 5, the filter device 100 includes a lower cover 130 and guide ribs 140, the lower cover 130 is located at a lower side of the cover housing 120, the lower cover 130 is disposed at a side of the mounting plate assembly 110 away from an inner circumferential surface of the washing tub 200, the guide ribs 140 are located between the mounting plate assembly 110 and the lower cover 130 and spaced apart from each other in a width direction of the filter device 100 to define a guide passage 140a, and the guide passage 140a is communicated with the water inlet 120 aa. That is, the guide ribs 140, the mounting plate assembly 110, and the lower cover 130 cooperate to form the guide passage 140 a. The guide passage 140a is located at a lower side of the water inlet 120aa and communicates the water inlet 120aa with the space inside the washing tub 200 to guide the water flow at the bottom of the washing tub 200 into the water inlet 120aa intensively and rapidly.

In some embodiments, referring to fig. 4 and 5, the number of the guide ribs 140 is two, two guide ribs 140 are located between the mounting plate assembly 110 and the lower cover 130 and are spaced apart from each other in the width direction of the filter device 100, and the two guide ribs 140, the mounting plate assembly 110 and the lower cover 130 cooperate to form a flow guide channel 140 a.

The upper side corresponds to the top side direction, the lower side corresponds to the bottom side direction, the upper side corresponds to the direction toward the ceiling, and the lower side corresponds to the direction toward the floor.

The manner in which the laundry treating apparatus performs the lint discharging process is not limited, and for example, in some embodiments, the lint discharging process may be separately operated. For example, a self-cleaning key for starting a lint discharge program may be provided on a control panel of the laundry treating apparatus. When a user wants to clean the filtering apparatus 100, the user may activate the lint discharging process by activating the self-cleaning key, so as to achieve self-cleaning of the filtering apparatus 100. In other embodiments, the lint removal program may be embedded in the washing mode, i.e., the self-cleaning of the filter device 100 is achieved during the washing process. Thus, the self-cleaning of the filter device 100 can be realized in the washing process, the user does not need to start the self-cleaning program regularly, and the user experience is good.

The specific manner in which the lint discharging program can be embedded in the washing mode is not limited, and in one embodiment, the lint discharging beat is embedded in the pulsator 300 beat in the entire washing cycle. In this way, the pulsator 300 is switched from a cleaning beat to a thread-waste discharging beat, the pulsator 300 is rotated at a set rotation speed, and an upward water current formed by the rotation speed and acceleration of the pulsator 300 impacts thread waste in the thread waste chamber 120a, so that the thread waste is discharged to the discharge passage 110a together. The lint discharging cycle can be performed several times in at least one cycle of each of washing and rinsing, so that the self-cleaning of the filtering apparatus 100 can be realized by using the washing water in the washing tub 200 during the washing process, thereby saving water resources and being more environment-friendly and energy-saving.

In one embodiment, the lint removal process is performed prior to performing the dehydration during the dehydration stage in at least one cycle of each of the washing, rinsing and dehydrating. Specifically, the lint discharging procedure may be: when the water level is lowered to a predetermined level, the pulsator 300 and the washing tub 200 rotate at a predetermined speed for a predetermined time, and the water in the washing tub 200 collides with the lint in the lint chamber 120a, so that the lint is discharged to the discharge passage 110 a. After the draining process is completed, a normal dewatering process is performed, such as high-speed dewatering rotation of the pulsator 300 and the washing tub 200, to drain the water in the washing tub 200. By the design, the self-cleaning of the filtering device 100 can be realized by using the washing water in the washing drum 200 in the washing process, so that the water resource is saved, and the environment is protected and the energy is saved.

In some embodiments, referring to fig. 3 and 5, the lint chamber 120a is formed with a water inlet 120aa along at least one side of the width direction of the filter device 100. Illustratively, in one embodiment, the lint chamber 120a is formed with a water inlet 120aa at one side in the width direction of the filter device 100. In another embodiment, both sides of the lint chamber 120a in the width direction of the filter apparatus 100 are formed with the water inlet 120 aa. For convenience of presentation, the inlet port 120aa of the lint chamber 120a in the width direction of the filter device 100 is defined as a second inlet port 120aa ″, so that the flow of water in the washing tub 200 can enter the lint chamber 120a through the second inlet port 120aa ″ in the width direction of the filter device 100. In washing, the water flow at the higher position in the washing drum 200 flows substantially in the circumferential direction, that is, the water flow at the higher position flows substantially in the width direction of the filtering device 100, so that the water flow in the washing drum 200 enters the lint chamber 120a through the second water inlet 120aa ″.

It is understood that the longitudinal direction of the filter device 100 coincides with the up-down direction, and the width direction of the filter device 100 is perpendicular to the longitudinal direction thereof.

It should be noted that in some embodiments, the lint cavity 120a may have only the first water inlet 120 aa' at the bottom side. In other embodiments, the lint cavity 120a may have only a second water inlet 120aa ″ along the width direction of the filter apparatus 100. In still other embodiments, referring to fig. 4 and 5, the lint cavity 120a may have both a first water inlet 120 aa' at the bottom side and a second water inlet 120aa ″ along the width direction of the filter device 100. Design like this, first water inlet 120 aa' and second water inlet 120aa "all can intake, and rivers not only can realize high-efficient filtration in can a large amount of, the quick line bits chamber 120a that gets into, still are convenient for realize the high-efficient line bits of discharging.

The specific location of the second water inlet 120aa ″ is not limited, and for example, in some embodiments, referring to fig. 5, the second water inlet 120aa ″ may be formed on a side of the cover case 120 in the width direction of the filter device 100. In one embodiment, both side surfaces of the cover case 120 in the width direction of the filter device 100 are formed with the second water inlet ports 120aa ″. Thus, the cover case 120 can be manufactured through an integral injection molding process, which is simple and low in manufacturing cost.

In an embodiment, referring to fig. 3 and 5, the mounting plate assembly 110 includes a flow guide member 111 located outside the lint cavity 120a, the flow guide member 111 is disposed at one side of the water inlet 120aa along the width direction of the filtering apparatus 100, and a portion of the flow guide member 111 near the water inlet 120aa is higher than a portion of the flow guide member 111 far from the water inlet 120 aa. That is, the flow guide 111 is located at one side of the second water inlet 120aa ″ in the width direction of the filter device 100, and the flow guide 111 guides the water flow into the lint chamber 120a from substantially the bottom to the top, so that the water flow entering from the second water inlet 120aa ″ can also impact the lint upward during the lint discharging process.

The number of the flow guide members 111 is not limited, and in some embodiments, the number of the flow guide members 111 may be one. In other embodiments, referring to fig. 3, the number of the flow guiding members 111 is multiple, and the flow guiding members 111 located on the same side of the second water inlet 120aa ″ are arranged at intervals along the length direction of the filtering apparatus 100. In this way, the plurality of flow guide members 111 can guide flow more evenly and effectively.

The specific structural shape of the flow guiding element 111 is not limited, and for example, in an embodiment, referring to fig. 3 and 5, the flow guiding element 111 is substantially a sheet structure, the top surface of the flow guiding element 111 is a flow guiding surface for guiding the water flow, and the flow guiding element 111 gradually inclines upwards from a direction away from the second water inlet 120aa ″ to a direction close to the second water inlet 120aa ″. Thus, the flow guide surface is substantially an inclined surface gradually inclined upward from a direction away from the second water inlet port 120aa ″ to a direction close to the second water inlet port 120aa ″ so as to guide the water flow upward into the lint chamber 120 a.

In one embodiment, referring to fig. 4 and 5, the filtering apparatus 100 includes a one-way member 150, and the one-way member 150 is located in the lint chamber 120a to control the water flow in the washing tub 200 to enter the lint chamber 120a in one direction through the water inlet 120 aa. That is, the water flow in the washing tub 200 can enter the lint chamber 120a through the check member 150, and the water flow in the lint chamber 120a cannot flow out of the lint chamber 120a through the check member 150. In this way, the one-way member 150 can restrict the water flow from entering the lint chamber 120a through the water inlet 120aa in one direction, and prevent the water flow in the lint chamber 120a from flowing out of the lint chamber 120a with the lint.

In one embodiment, referring to fig. 4 and 5, one end of the one-way member 150 is rotatably disposed on the mounting plate assembly 110 or the cover casing 120, the other end of the one-way member 150 is a free end, water flow in the washing tub 200 impacts the one-way member 150 to open the water inlet 120aa, and water flow in the lint chamber 120a impacts the one-way member 150 to close the water inlet 120 aa. That is, the water flow in the washing tub 200 impacts the one-way member 150, so that the free end of the one-way member 150 is rotated in a direction away from the water inlet 120aa, thereby opening the water inlet 120 aa. The water flow in the lint chamber 120a strikes the one-way member 150, so that the free end of the one-way member 150 is rotated in a direction close to the water inlet port 120aa, thereby closing the water inlet port 120 aa. Thus, the water inlet 120aa is opened or closed by the water flow in the washing barrel 200 and the water flow control one-way element 150 in the lint cavity 120a, the operation is simple, electronic components such as an electromagnetic valve are avoided, the structure is simple, the cost is low, and the assembly is easy.

The way that the one-way member 150 closes the water inlet 120aa is not limited, and for example, in an embodiment, an end surface of the one-way member 150 facing the water inlet 120aa can close the water inlet 120 aa.

In some embodiments, both the first water inlet 120 aa' and the second water inlet 120aa ″ are provided with a one-way element 150.

In some embodiments, the first water inlet 120 aa' may not be provided with the check member 150. Since the water flow in the washing tub 200 continuously enters the first water inlet 120aa ' from bottom to top during the rotation of the pulsator 300 and/or the washing tub 200, the lint in the lint cavity 120a is kept suspended in the water in the lint cavity 120a under the action of the water flow and does not escape from the first water inlet 120aa ', and therefore, the first water inlet 120aa ' may not be provided with the one-way member 150.

In one embodiment, referring to fig. 2, 4 and 5, the mounting plate assembly 110 includes a mounting plate 112 and a lining plate 113, the mounting plate 112 is disposed on an inner circumferential surface of the washing tub 200 to cooperate to form a discharge passage 110a, a lint outlet 110b is formed on the mounting plate 112, the lining plate 113 is disposed on a side of the mounting plate 112 close to the cover shell 120, the one-way member 150 is rotatably disposed on the lining plate 113, and the cover shell 120 cooperates with the lining plate 113 to form a lint chamber 120 a. The mounting plate 112 and the backing plate 113 may be independent of each other, i.e., the mounting plate 112 and the backing plate 113 may be manufactured separately, which may simplify the structural shape of the individual structural members. When the filtering device 100 is assembled, the unidirectional element 150 can be assembled to the lining plate 113 to form a whole, and then the whole is assembled to the mounting plate 112, so that the assembly difficulty of the structural element by an operator is low, and the operation is convenient.

In another embodiment, the liner plate 113 is not disposed on the mounting plate 112, the one-way member 150 is rotatably disposed on the mounting plate 112, and the cover shell 120 and the mounting plate 112 cooperate to form the lint chamber 120 a. By the design, the number of structural parts is reduced, and the operation flow is reduced.

In one embodiment, the bottom side of the mounting plate 112 and the bottom side of the cover housing 120 are spaced to form a bottom side opening, thereby forming a first water inlet 120 aa'. In another embodiment, referring to fig. 4, the bottom side of the liner plate 113 and the bottom side of the cover case 120 are spaced apart to form a bottom side opening, thereby forming a first water inlet 120 aa'.

In one embodiment, lower cover 130 may be snap-fit to the lower portion of mounting plate 112, such that lower cover 130 and mounting plate 112 may be quickly assembled to cooperatively form flow channel 140 a.

The cover housing 120 is removably attachable to the mounting plate 112 such that, when necessary, such as with increased use, when the filter screens of the cover housing 120 need to be more thoroughly cleaned, the cover housing 120 can be removed from the mounting plate 112, the cover housing 120 and filter screens can be rinsed directly with water, and the rinsed cover housing 120 can be reassembled to the mounting plate 112. For example, in one embodiment, the bottom of the cover housing 120 may be mated with the mounting plate 112 by a snap fit, and the top of the cover housing 120 may be mated with the mounting plate 112 by a snap fit. For example, during assembly, the bottom of the cover housing 120 may be inserted into the mounting plate 112 from top to bottom, and then a force may be applied to press the cover housing 120 toward the washing tub 200, so that the top of the cover housing 120 is snapped onto the mounting plate 112, thereby facilitating quick assembly of the cover housing 120 and the mounting plate 112.

In an embodiment, referring to fig. 5, the guiding rib 140 and the guiding element 111 may be disposed on the mounting plate 112, for example, the guiding rib 140, the guiding element 111 and the mounting plate 112 may be an integral injection molding structure. Thus, the process is simple and the manufacturing cost is low.
