[0051] Please refer to Figures 1 to 3 , Figure 1 FIG. 2 is a schematic perspective view of a drum-type washing machine according to one embodiment of the present invention. Figure 2 for Figure 1 The cross-sectional view at AA in the middle. Figure 3 for Figure 1 The present application also proposes a drum-type washing machine 10 , which generally includes a housing and an inner drum 100 .

[0052] The shell has an outer cylinder 110 inside, and an inner cylinder 100 is sleeved in the outer cylinder 110. The inner cylinder 100 has multiple lifting ribs 200, and each lifting rib 200 defines a storage chamber 212. The lifting rib 200 has two water inlet holes, and the two water inlet holes 216 are respectively provided with openable and closable filter components 220, which are configured so that one of the two filter components 220 is opened and the other is closed, so that washing water enters the storage chamber 212 from the opened filter component 220, and the lint in the washing water is filtered by the closed filter component 220 and collected in the storage chamber 212.

[0053] In this embodiment, the outer drum 110 can be arranged in the housing through a hanging assembly, and the outer drum 110 is generally a sealed structure for holding water. The inner drum 100 is sleeved in the outer drum 110 for holding clothes, and the inner drum 100 has a plurality of dehydration holes (not shown in the figure), so that the water in the outer drum 110 flows into the inner drum 100 through the dehydration holes to soak the clothes in the inner drum 100, and the water in the inner drum 100 flows out to the outer drum 110 through the dehydration holes. When the inner drum 100 rotates at a high speed, the water on the clothes in the inner drum 100 is discharged to the outer drum 110 through the dehydration holes, so as to achieve the purpose of washing and dehydrating the clothes.

[0054] A plurality of lifting ribs 200 are arranged on the inner wall of the inner drum 100. During the rotation of the inner drum 100, the plurality of lifting ribs 200 contact the clothes alternately and lift the clothes so that the clothes fall from a height, forming a falling effect to achieve washing and rinsing of the clothes.

[0055] In order to more clearly express the structure and function of the lifting ribs 200 in the embodiment of the present invention, the following description will be given by taking one of the lifting ribs 200 as an example.

[0056] Please refer to Figures 4 to 7 In this embodiment, the lifting rib 200 includes a body and two filter assemblies 220. The interior of the body defines a storage chamber 212, and the body has two oppositely disposed working surfaces, which are respectively referred to as a first working surface 214 and a second working surface 215 for ease of description. The first working surface 214 and the second working surface 215 together form a raised structure for lifting clothes.

[0057] Each working surface is provided with a water inlet hole 216 communicating with the receiving chamber 212 , that is, both the first working surface 214 and the second working surface 215 are provided with a water inlet hole 216 communicating with the receiving chamber 212 , and water in the inner cylinder 100 can flow into the receiving chamber 212 along the water inlet hole 216 .

[0058] During the washing process, the thread scraps stuck on the clothes float in the water. In this embodiment, the drum-type washing machine 10 can collect the thread scraps in the water. A filter assembly 220 is respectively arranged at the water inlet hole 216 of the first working surface 214 and the second working surface 215. When the inner drum 100 rotates clockwise, the water in the inner drum 100 will flow through the first working surface 214, and the filter assembly 220 arranged on the first working surface 214 opens the water inlet hole 216 on the first working surface 214 under the action of the thrust of the water flow. At this time, the water flow containing thread scraps enters the storage chamber 212. At the same time, the filter assembly 220 arranged on the second working surface 215 is in a position to close the water inlet hole 216 on the second working surface 215. When the water containing thread scraps passes through the water inlet hole 216 on the second working surface 215, the thread scraps will be filtered into the storage chamber 212, thereby achieving the purpose of collecting thread scraps. Conversely, when the inner drum 100 rotates counterclockwise, the purpose of collecting thread scraps can also be achieved.

[0059] See also Figures 4 to 8In some embodiments of the present application, the filter assembly 220 includes a filter shield 222 and a first reset member 224. The filter shield 222 is pivotally connected to the inner side of the corresponding working surface, and the filter shield 222 has a filter screen portion 225 opposite to the water inlet hole 216 of the working surface. The first reset member 224 is used to provide the filter shield 222 with a first force to close the water inlet hole 216. And the filter shield 222 is configured to overcome the first force under the thrust of the water flow and rotate toward the inside of the storage chamber 212 to open the water inlet hole 216.

[0060] In this embodiment, the filter shield 222 is pivotally connected to the inner side of the first working surface 214 or the second working surface 215, and can rotate relative to the water inlet hole 216 to close or open the water inlet hole 216. During the rotation of the inner cylinder 100, when the water in the inner cylinder 100 flows through the first working surface 214, the filter shield 222 arranged at the first working surface 214 is pushed by the water flow, so that the filter shield 222 rotates in the direction away from the water inlet hole 216, and the water flow containing the wire scraps will enter the storage chamber 212. At the same time, the filter shield 222 on the second working surface 215 is in a position to close the water inlet hole 216 on the second working surface 215, and the filter screen part 225 of the filter shield 222 can filter the water flow passing through the filter shield 222, so that the wire scraps in the water are filtered in the storage chamber 212.

[0061] In order to make the filter shield 222 in a position to close the water inlet hole 216 on the working surface to filter the wire scraps, the filter assembly 220 in this embodiment also includes a first reset member 224, and the function of the first reset member 224 is to provide the filter shield 222 with a first force to close the water inlet hole 216. When the inner cylinder 100 rotates clockwise and the filter shield 222 at the first working surface 214 is subjected to the thrust of the water flow that can overcome the first force provided by the first reset member 224, the filter shield 222 will be opened, so that the water flow containing the wire scraps enters the storage chamber 212. When the thrust of the water flow on the filter shield 222 at the first working surface 214 is less than the first force provided by the first reset member 224, the filter shield 222 will be closed.

[0062] In some embodiments of the present application, the first reset member 224 is a torsion spring sleeved on the pivot shaft 226 of the filter shield 222, wherein the elastic force of the torsion spring provides the first force for the filter shield 222. On this basis and according to the actual working conditions of the drum-type washing machine 10, those skilled in the art select a torsion spring suitable for the specifications of this embodiment, so that when the water flow thrust on the filter shield 222 is less than the first force provided by the torsion spring, the filter shield 222 can be in a position to close the water inlet hole 216 there, and when the water flow thrust on the filter shield 222 is greater than the first force provided by the torsion spring, the filter shield 222 can be in a position to open the water inlet hole 216 there.

[0063] Please refer to Fig. 9 In some other embodiments of the present application, the first reset member 224 includes two magnets 227 that cooperate with each other, one of which is disposed on the filter shield 222, and the other is disposed on the inner side of the working surface. In this embodiment, two magnets 227 with attractive forces are used to provide the filter shield 222 with a force to close the water inlet hole 216.

[0064] It should be noted that, based on the knowledge of the embodiments of the present application, those skilled in the art may also adopt other forms of the first reset member 224 to provide the first force for the filter baffle 222 to close the water inlet hole 216, which will not be elaborated here.

[0065] Please refer to Figures 4 to 8 In some embodiments of the present application, each lifting rib 200 also has a wire chip discharge outlet 219 , and a wire chip discharge component for opening and closing the wire chip discharge outlet 219 is provided at the wire chip discharge outlet 219 .

[0066] In this embodiment, the body has a mounting surface 218 connected to the inner cylinder 100, and the mounting surface 218 can be arranged between the first working surface 214 and the second working surface 215, and the mounting surface 218 is in contact with the surface of the inner cylinder 100. A wire scrap discharge port 219 is provided on the mounting surface 218, which is used to discharge the wire scraps retained in the storage chamber 212, and the lifting rib 200 also includes a wire scrap discharge assembly, which can be opened and closed at the wire scrap discharge port 219, and is configured to open the wire scrap discharge port 219 under the action of centrifugal force when the inner cylinder 100 rotates.

[0067] In some other embodiments of the present application, the wire scrap discharge assembly includes: a baffle 310 and a second reset member 320. The baffle 310 is pivotally connected to the lifting rib 200 at the wire scrap discharge outlet 219, and is used to open or close the wire scrap discharge outlet 219. The second reset member 320 is sleeved on the pivot axis of the baffle 310, and is used to provide the baffle 310 with a second force to close the wire scrap discharge outlet 219; and the baffle 310 is configured to overcome the second force under the action of centrifugal force when the inner cylinder 100 rotates and rotate away from the wire scrap discharge outlet 219 to open the wire scrap discharge outlet 219.

[0068] In this embodiment, the baffle 310 is pivotally connected to the body at the wire scrap outlet 219, so as to close the wire scrap outlet 219. When the inner cylinder 100 rotates, the baffle 310 rotates away from the wire scrap outlet 219 under the action of centrifugal force to open the wire scrap outlet 219 and discharge the wire scraps.

[0069] Please refer to Figure 4 , usually the washing process of the drum washing machine 10 can be divided into the initial washing stage, the rinsing stage and the dehydration stage, etc., and the rotation speed of the inner drum 100 in the initial washing stage and the rinsing stage is generally lower than the rotation speed of the inner drum 100 in the dehydration stage. In some embodiments of the present application, in order to improve the working efficiency of the filter assembly 220, the lint discharge port 219 is maintained in a closed state when the drum washing machine 10 is in the initial washing stage or the rinsing stage. If the lint discharge port 219 is in an open state in the initial washing stage or the rinsing stage, the water entering the storage chamber 212 will flow directly from the lint discharge port 219 to the outer drum 110 without being filtered by the filter assembly 220. This part of the water will return from the outer drum 110 through the dehydration hole to the inner drum 100, which will reduce the efficiency of the lifting rib 200 in collecting lint. In order to solve the above problem, in the embodiment of the present application, those skilled in the art can select a second reset member 320 of appropriate specifications according to the operating conditions of the drum washing machine 10 (parameters such as the rotation speed of the inner drum 100 during the washing stage) to ensure that the centrifugal force applied by the inner drum 100 on the baffle 310 during the washing stage is less than the second force provided by the second reset member 320, thereby placing the baffle 310 in a position to close the lint discharge port 219.

[0070] In some other embodiments of the present application, the second force provided by the second reset member 320 is configured to be greater than the centrifugal force applied by the inner drum 100 to the baffle 310 during the washing stage, and the second force provided by the second reset member 320 is less than the centrifugal force applied by the inner drum 100 to the baffle 310 during the dehydration stage. That is, the baffle 310 is in a position to close the lint discharge port 219 during the washing stage, and the baffle 310 is in a position to open the lint discharge port 219 during the dehydration stage, so that the lint in the storage chamber 212 is discharged during the dehydration stage.

[0071] In some embodiments of the present application, the baffle 310 is of a double-open type, that is, there are two baffles 310, and the two baffles 310 are respectively arranged on both sides of the wire chip discharge outlet 219, and the wire chip discharge outlet 219 is opened or closed by rotating simultaneously.

[0072] See also Fig.10 In some other embodiments of the present application, the baffle 310 can also be configured as one, one side of which is pivotally connected to the body at the wire scrap discharge outlet 219, and the wire scrap discharge outlet 219 is opened or closed by rotating.

[0073] In some embodiments of the present application, the mounting surface 218 is inclined toward the wire scrap discharge port 219 , so that the wire scraps in the storage chamber 212 are close to the wire scrap discharge port 219 for easy discharge.

[0074] See also Figure 4 In some embodiments of the present application, the inner cylinder 100 has an opening 410 connected to the wire scrap discharge port 219, which is used to discharge the wire scraps from the inner cylinder 100 through the opening 410. In this embodiment, the inner cylinder 100 has an opening 410 at a position connected to the mounting surface 218, which is used to provide the required rotation space for the baffle 310 to rotate, and when the baffle 310 is opened, the wire scraps are discharged through the opening 410. Finally, the wire scraps are discharged through the drain pipe 130 connected to the outer cylinder 110.

[0075] The working principle of the present invention is as follows: when the water flow in the inner drum 100 of the drum washing machine 10 flows through the first working surface 214 in the initial washing stage or the rinsing stage, the first working surface 214 is subjected to the thrust of the water flow and the filter component 220 arranged on the first working surface 214 is opened under the action of the thrust of the water flow, so that the water flow enters the storage chamber 212 from the water inlet hole 216 on the first working surface 214. At this time, the filter component 220 on the second working surface 215 is in a position to close the water inlet hole 216 there. When the water flow flows out of the storage chamber 212 from the water inlet hole 216 on the second working surface 215, the filter part 225 on the filter component 220 there filters the wire scraps in the water flow and retains them in the storage chamber 212. During the dehydration process of the drum type washing machine 10, as the inner drum 100 rotates, the baffle 310 provided at the lint discharge outlet 219 overcomes the force of the second reset member 320 under the action of centrifugal force to open the lint discharge outlet 219, so that the lint in the storage chamber 212 is discharged from the lint discharge outlet 219. Through the above two processes, the drum type washing machine 10 is respectively implemented to automatically collect and discharge lint without user intervention, thereby improving the user experience.

[0076] Please refer to Fig.11In some embodiments of the present application, the drum washing machine 10 also includes a controller 500, the controller 500 includes a processor 510 and a memory 520, the memory 520 stores a computer program 522, and the computer program 522 is used to implement a lint self-cleaning control method for a washing machine when executed by the processor 510.

[0077] Please refer to Fig.12 , Fig.12 The present invention is a schematic flow chart of a method for controlling the self-cleaning of lint according to an embodiment of the present invention. The present invention provides a method for controlling the self-cleaning of lint for a washing machine, wherein a storage chamber 212 for collecting lint is defined in a lifting rib 200 of the washing machine, and the lifting rib 200 has two water inlet holes 216, and the two water inlet holes 216 are respectively provided with filter components 220 that can be opened and closed, and the control method includes:

[0078] Step S110, obtaining the weight of the laundry;

[0079] Step S120, determining the washing stage to be performed by the washing machine;

[0080] Step S130, determining whether the washing stage belongs to the lint collection process;

[0081] Step S142, if yes, determine the water intake amount and the running time of the washing stage according to the weight;

[0082] Step S150, performing a washing phase according to the determined water intake volume and operating time.

[0083] In the process of collecting lint, one of the two filter components 220 is opened and the other is closed, so that the washing water enters the storage chamber 212 from the opened filter component 220, and the lint in the washing water is filtered by the closed filter component 220 and collected in the storage chamber 212.

[0084] In this embodiment, the user can start the lint self-cleaning program according to actual needs, and the control method can realize automatic lint cleaning without human intervention, thereby improving the user's experience.

[0085] In the above steps, step S110 obtains the weight of the laundry to be washed. In this step, the washing machine can obtain the weight of the laundry put into the washing machine by the user through the weighing device provided inside the washing machine. For example, in some specific embodiments, the washing machine can realize the weighing of the laundry through the pressure sensor on the inner drum 100, and transmit the weighing electrical signal to the controller 500 of the washing machine. Of course, those skilled in the art can also weigh the laundry to be washed and obtain its weight through other methods. In this embodiment, the method of obtaining the weight of the laundry is not particularly limited.

[0086] In step S120, the washing stage to be performed by the washing machine is determined. The washing stage is a preset washing mode of the washing machine, which generally includes an initial wash stage, a rinsing stage, a dehydration stage, etc. Usually, after the user puts in the laundry, he will select a preset washing process of the washing machine, and the washing process can be a combination of multiple washing stages. For example, the washing process of the standard mode may include: a combination of an initial wash stage, at least one rinsing stage and a dehydration stage. In this step, the washing stage to be performed by the washing machine can be determined by accessing the washing program of the washing machine.

[0087] In step S130, it is determined whether the washing stage belongs to the lint collection process. During the lint collection process, the change in the rotation speed of the inner drum of the washing machine can be used to achieve the purpose of collecting lint in the washing water. In one embodiment of the present application, a storage chamber 212 for collecting lint is defined in the lifting rib 200 of the washing machine, and each lifting rib 200 has two water inlet holes 216, and the two water inlet holes 216 are respectively provided with openable and closable filter components 220, one of the two filter components 220 is opened and the other is closed, so that the washing water enters the storage chamber 212 from the opened filter component 220, and the lint in the washing water is filtered by the closed filter component 220, so as to be collected in the storage chamber 212.

[0088] In another embodiment of the present application, two water inlet holes 216 are respectively disposed on two opposite working surfaces of the lifting rib 200, and the working surfaces are used to contact the clothes during the rotation of the washing machine inner drum 100, and lift the clothes so that the clothes fall from a high place, forming a falling effect to achieve the washing of the clothes. For the convenience of description, the two opposite working surfaces are referred to as the first working surface 214 and the second working surface 215 below.

[0089] When the inner drum 100 rotates clockwise, the water in the inner drum 100 will flow through the first working surface 214, and the filter assembly 220 disposed on the first working surface 214 opens the water inlet hole 216 on the first working surface 214 under the action of the water flow thrust, and the washing water containing the wire scraps flows into the storage chamber 212 at this time, and the filter assembly 220 disposed on the second working surface 215 is in a position to close the water inlet hole 216 on the second working surface 215, and the washing water containing the wire scraps will filter the wire scraps into the storage chamber 212 when passing through the water inlet hole 216 on the second working surface 215, so as to achieve the purpose of collecting the wire scraps. Conversely, when the inner drum 100 rotates counterclockwise, the purpose of collecting the wire scraps can also be achieved.

[0090] In step S142, if the washing stage to be performed by the washing machine belongs to the lint collection process, the water intake and the running time of the washing stage are determined according to the weight. In this embodiment, when the washing stage to be performed by the washing machine belongs to the lint collection process, the water intake and the running time of the washing stage need to refer to the lint cleaning factor, that is, the water intake and the running time of the washing stage of the washing machine with this control method do not adopt the traditional preset program. In this embodiment, the water intake and the running time of each washing stage also need to be determined in combination with the lint cleaning factor.

[0091] In some other embodiments of the present application, the water intake of each washing stage can be configured to be the same or different, and similarly, the running time of each washing stage can also be configured to be the same or different. For example, the initial washing stage and the rinsing stage can be set with different water intake and running time according to their washing purposes. However, in this embodiment, the water intake and running time of each washing stage also need to be determined in combination with the debris cleaning factor.

[0092] In step S150, the washing stage is performed according to the determined water intake and running time. After the water intake and running time are determined in the above step S142, the washing machine can wash the clothes according to the preset washing program.

[0093] In some other embodiments of the present application, the step of determining the water intake volume and the running time of the washing stage according to weight includes: querying the water intake volume and the running time corresponding to the weight from a preset correspondence relationship, wherein the correspondence relationship pre-stores the correspondence between the weight, water intake volume and running time in each lint collection process.

[0094] In the washing machine of this embodiment, there is a preset correspondence between the weight, water intake and running time in each lint collection process, and the washing machine can determine the water intake and running time of this stage according to the correspondence. The correspondence is the conclusion drawn by the inventor through experiments, and the inventor found that: in this washing machine, the lint collection rate, the weight of the laundry, the water intake and the running time have a certain regularity, and the regularity shows that when the weight of the laundry is constant, the lint collection rate will change with the change of the water intake and the running time, and when the water intake and the running time reach a certain value, the lint collection rate will reach the maximum. Specifically, the correspondence is the relationship between the weight of the laundry, the water intake and the running time when the lint collection rate is maximized, in order to improve the lint collection efficiency of the washing machine. And the inventor also collected the correspondence of multiple washing stages in parallel, such as the relationship between the weight, water intake and running time in the initial washing stage, the relationship between the weight, water intake and running time in the rinsing stage, etc.

[0095] Please refer to Fig.13 , Fig.13 is a schematic flow chart of a wire scrap self-cleaning control method according to another embodiment of the present invention. In some other embodiments of the present application, the lifting rib 200 further has a wire scrap discharge outlet 219, and a wire scrap discharge component for opening and closing the wire scrap discharge outlet 219 is provided at the wire scrap discharge outlet 219; and

[0096] After the washing phase is performed according to the determined water intake and running time in step S150 , step S160 is executed to discharge the lint, so that the lint discharge assembly is in a position to open the lint discharge port 219 to discharge the lint collected in the storage chamber 212 .

[0097] In this embodiment, the step S160 of discharging the lint is after the step S150, that is, the washing stage to be performed by the washing machine no longer belongs to the lint collection process. In some specific embodiments, the washing stage can be a dehydration stage. In this embodiment, the lint discharge assembly can use the centrifugal force provided by the rotation of the inner drum 100 during the dehydration stage to open the lint discharge assembly so that the lint is discharged.

[0098] Please refer to Fig.13 In step S130, it is determined whether the washing stage is a lint collection process. If not, step S144 is executed to perform the washing stage according to the preset washing parameters.

[0099] In some embodiments of the present application, the washing stage belonging to the lint collection process includes: an initial washing stage and a rinsing stage.

[0100] In this embodiment, when determining whether the washing stage is a lint collection process in step S130, if it is obtained that the washing stage to be performed by the washing machine is the initial washing stage or the rinsing stage, steps S142, S150 and S160 are executed in sequence, and the self-cleaning goal of lint is finally achieved. If it is obtained that the washing stage to be performed by the washing machine is other stages (such as the dehydration stage), step S144 is executed.

[0101] The purpose of automatically collecting lint in washing water is achieved through the control method of the embodiment of the present application, and because the data correspondence applicable to the washing machine is also saved in the preset program of the washing machine, the lint collection efficiency of the washing machine is maximized, thereby improving the user experience.
