Description

Technical Field

[0001] This disclosure relates to the field of household appliance technology, and in particular to a washing machine. Background Technology

[0002] Washing machines are clothing processing devices that convert electrical energy into mechanical energy to wash clothes. They are now commonplace in almost every household.

[0003] During the washing process, foreign objects generated by clothes are usually collected by a foreign object filter installed in the washing machine's drain path to reduce the amount of foreign objects in the discharged water and prevent clogging of the drain channel. However, due to water pressure and accumulation during drainage, foreign objects often adhere tightly to the foreign object filter and cannot be easily removed. This requires manual removal or the use of tools to clean the foreign objects, which is time-consuming and inconvenient. Utility Model Content

[0004] In view of this, the purpose of this disclosure is to provide a washing machine that improves the technical problem of difficulty in cleaning foreign objects collected in the drain filter in the prior art.

[0005] To achieve at least one of the above objectives, this disclosure provides the following technical solutions:

[0006] In a first aspect, a washing machine is provided, comprising:

[0007] Box;

[0008] A washing drum, which is installed inside the cabinet, is used for washing clothes;

[0009] A drain filter device, installed in the drain path of the washing machine, is used to collect foreign objects in the water discharged from the washing machine. The drain filter device includes:

[0010] The housing has an internal cavity with a port located on the side of the cavity near the outer end face of the washing machine.

[0011] The receiving cavity is configured to communicate with the drainage path and to allow water flowing in the drainage path to pass through;

[0012] A sealing section is detachably installed at the port to open or close the receiving cavity;

[0013] A foreign object storage unit is connected to one end of the sealing unit and can be placed into the receiving cavity. The foreign object storage unit includes:

[0014] The first split structure has a first connecting end and a first end wall disposed opposite to each other along a first direction, and the first connecting end is fixedly connected to the sealing part;

[0015] The second split structure has a second connecting end and a second end wall disposed opposite to each other along a first direction, and the second connecting end is movably connected to the first connecting end by a shaft;

[0016] The first and second substructures have both closed and open states.

[0017] The closed state is configured such that the second split structure rotates about an axis, causing at least a portion of the first end wall to contact the second end wall;

[0018] In the closed state, a filter chamber is formed between the first split structure and the second split structure, and an opening is formed at the top of the filter chamber, which is configured as the water inlet of the filter chamber.

[0019] At least one of the first split structure and the second split structure is provided with a filter channel, which is configured to retain at least a portion of the foreign matter contained in the water in the filter chamber and to allow the water in the filter chamber to be discharged.

[0020] When the foreign object storage section is placed into the receiving cavity, the first split structure and the second split structure are in a closed state.

[0021] The open state is configured at least to allow the second split structure to rotate about an axis, causing the second end wall to move away from the first end wall, thereby opening the filter chamber.

[0022] In the above technical solution, the foreign matter storage part is divided into two openable and closable structures, namely a first split structure and a second split structure, and the top of the filter cavity formed by the two split structures is also formed with an opening. When the foreign matter storage part is removed and the foreign matter inside is cleaned, the filter cavity formed by the two split structures can be opened by opening the first split structure and the second split structure, so as to loosen the foreign matter and reduce the adhesion strength of the foreign matter on the foreign matter storage part. At the same time, the opening can be made to face downward, and under the action of gravity, the foreign matter can fall out of the filter cavity through the opening, thus achieving the effect of easily removing the foreign matter collected in the filter cavity.

[0023] In some embodiments, the first split structure includes:

[0024] A first bottom wall is provided, extending along a first direction;

[0025] The first sidewall is connected to the end of the first bottom wall away from the second split structure and is located above the first bottom wall;

[0026] The first end wall is connected to the end of the first bottom wall away from the sealing part and is located above the first bottom wall;

[0027] The second substructure includes:

[0028] A second bottom wall is provided, extending along the first direction;

[0029] The second sidewall is connected to the end of the second bottom wall away from the first split structure and is located above the second bottom wall;

[0030] The second end wall is connected to the end of the second bottom wall away from the sealing part and is located above the second bottom wall;

[0031] In the closed state, the first bottom wall and the second bottom wall are joined together along the second direction, the first end wall and the second end wall are joined together along the second direction, and the first side wall and the second side wall are arranged opposite to each other along the second direction. The first bottom wall, the second bottom wall, the first end wall, the second end wall, the first side wall and the second side wall together form a filter cavity.

[0032] In the above technical solution, both the first split structure and the second split structure adopt a structural design in which the bottom wall, side wall and end wall are connected. In the closed state, the two bottom walls are joined together and the two side walls and two end walls surround the outer periphery above the two bottom walls. They can also cooperate with the end face of the sealing part, thus forming a filter cavity together, and the top of the filter cavity can form an opening. When cleaning foreign objects, opening the first split structure and the second split structure can separate the two bottom walls, the two side walls and the two end walls. Foreign objects attached to the bottom wall, side wall and end wall can be pulled during the opening process, thus loosening or directly detaching from the bottom wall, side wall and end wall, which can achieve the effect of easy cleaning of foreign objects.

[0033] In some embodiments, an elastic element is provided between the second split structure and the sealing part;

[0034] The elastic element is configured to drive the second split structure to rotate about an axis and enable the first and second split structures to be in a closed state.

[0035] Furthermore, a connecting plate is provided at one end of the second sidewall near the sealing part;

[0036] An installation space is provided between the side of the connecting plate away from the filter chamber and the end face of the sealing part facing the foreign matter storage part;

[0037] The installation space is configured to accommodate the elastic element and enable the elastic element to be connected between the connecting plate and the sealing part.

[0038] In the above technical solution, an elastic element is provided between the second split structure and the sealing part. The elasticity of the elastic element can drive the second split structure to rotate around the axis and realize the automatic closure of the second split structure and the first split structure without manual closure, which simplifies the operation of opening and closing the foreign object storage part. Moreover, the design of the elastic element can keep the first split structure and the second split structure in a closed state when they are placed in the receiving cavity.

[0039] In some embodiments, a toggle member is provided at one end of the connecting plate away from the sealing portion, and the toggle member protrudes from the side of the connecting plate away from the filter chamber.

[0040] The actuating element is configured to drive the second split structure to rotate about an axis by actuating the actuating element, and to compress the elastic element within the installation space so that the first split structure and the second split structure can be in the open state.

[0041] In the above technical solution, by setting a toggle member on the second split structure, the toggle member can be used to squeeze the elastic member to open the foreign object storage section, so that the first split structure and the second split structure are in the open state; moreover, the toggle member protrudes from the connecting plate, which facilitates the opening operation and helps guide the user to perform the pressing operation.

[0042] In some embodiments, a locking mechanism is provided between the first end wall and the second end wall;

[0043] The locking mechanism is configured to lock the first end wall and the second end wall in the closed state.

[0044] Furthermore, the locking mechanism is a snap-fit ​​structure, which includes a resilient clip and a slot;

[0045] One of the first end wall and the second end wall is connected to a flexible clip, and the other end wall is provided with a clip groove;

[0046] In the closed state, the elastic clip engages with the slot to lock the first end wall and the second end wall.

[0047] Alternatively, the locking mechanism is a magnetic structure, which includes a first magnet and a second magnet;

[0048] A first magnet is provided on one of the first end wall and the second end wall, and a second magnet is provided on the other end wall;

[0049] In the closed state, the first magnet and the second magnet are positioned opposite each other and attract each other to lock the first end wall and the second end wall.

[0050] In the above technical solution, a locking mechanism is provided between the first end wall and the second end wall. The locking mechanism can lock the first end wall and the second end wall to ensure that after the foreign object storage part is placed in the receiving cavity, the first split structure and the second split structure can remain in a closed state, preventing the filter cavity from being unable to effectively filter foreign objects due to the opening of the first split structure and the second split structure.

[0051] In some embodiments, a first protrusion structure is provided on the side of the first end wall away from the filter cavity;

[0052] A second protrusion structure is provided on the side of the second end wall away from the filter cavity;

[0053] A recessed structure is provided at the end of the housing opposite to the port;

[0054] When the foreign object storage section is placed into the receiving cavity, the first protruding structure and the second protruding structure can be inserted together into the recessed structure. Under the restriction of the recessed structure, the first protruding structure and the second protruding structure move closer to each other in the second direction to keep the first split structure and the second split structure in a closed state.

[0055] In the above technical solution, the cooperation of the first protruding structure, the second protruding structure and the recessed structure can limit the distance between the first split structure and the second split structure in the second direction, thereby ensuring that the first split structure and the second split structure can remain closed after the foreign object storage part is placed in the receiving cavity.

[0056] In some embodiments, a first comb-tooth structure is formed on the first bottom wall;

[0057] A second comb-tooth structure is formed on the second bottom wall;

[0058] In the closed state, the first comb tooth structure and the second comb tooth structure are staggered, and a gap is formed between the first comb tooth structure and the second comb tooth structure.

[0059] In the above technical solution, a first comb tooth structure and a second comb tooth structure are designed to be staggered between the first bottom wall and the second bottom wall. When it is necessary to clean foreign objects, the first split structure and the second split structure can be opened to separate the first comb tooth structure and the second comb tooth structure. Foreign objects attached to the first comb tooth structure and the second comb tooth structure can be easily detached along the direction of the comb teeth, and there will be no problem of difficulty in cleaning due to foreign objects entangled in the first comb tooth structure and the second comb tooth structure. Moreover, the gap between the first comb tooth structure and the second comb tooth structure can be used as a filter channel to improve the drainage capacity of the filter chamber.

[0060] Secondly, a washing machine is also provided, comprising:

[0061] Box;

[0062] A washing drum, which is installed inside the cabinet, is used for washing clothes;

[0063] A drain filter device, installed in the drain path of the washing machine, is used to collect foreign objects in the water discharged from the washing machine. The drain filter device includes:

[0064] The housing has an internal cavity with a port located on the side of the cavity near the outer end face of the washing machine.

[0065] The receiving cavity is configured to communicate with the drainage path and to allow water flowing in the drainage path to pass through;

[0066] A sealing section is detachably installed at the port to open or close the receiving cavity;

[0067] A foreign object storage unit is connected to one end of the sealing unit and can be placed into the receiving cavity. The foreign object storage unit includes:

[0068] The first split structure has a first connecting end and a first end wall disposed opposite to each other along a first direction;

[0069] The second split structure has a second connecting end and a second end wall disposed opposite to each other along the first direction;

[0070] The first connecting end and the second connecting end are movably connected to the sealing part via a shaft;

[0071] The first and second substructures have both closed and open states.

[0072] The closed state is configured such that at least one of the first split structure and the second split structure rotates about an axis, such that the first end wall and the second end wall are at least partially in contact;

[0073] In the closed state, a filter chamber is formed between the first split structure and the second split structure, and an opening is formed at the top of the filter chamber, which is configured as the water inlet of the filter chamber.

[0074] At least one of the first split structure and the second split structure is provided with a filter channel, which is configured to retain at least a portion of the foreign matter contained in the water in the filter chamber and to allow the water in the filter chamber to be discharged.

[0075] When the foreign object storage section is placed into the receiving cavity, the first split structure and the second split structure are in a closed state.

[0076] The open state is configured such that at least one of the first split structure and the second split structure rotates about an axis, causing the first end wall and the second end wall to move away from each other, thereby opening the filter chamber.

[0077] In the above technical solution, compared with the first aspect, the foreign matter storage part of this solution is divided into a first split structure and a second split structure, both of which can be movably connected to the sealing part by a shaft. Similarly, the foreign matter storage part can be made into two openable and closable structures, and the top of the filter cavity formed by these two structures also has an opening. When the foreign matter storage part is taken out and the foreign matter inside is cleaned, the filter cavity formed by these two structures can be opened by opening the first split structure and the second split structure, so as to loosen the foreign matter and reduce the adhesion strength of the foreign matter on the foreign matter storage part. At the same time, the opening can be made to face downward, and under the action of gravity, the foreign matter can fall out of the filter cavity through the opening, thus achieving the effect of easily removing the foreign matter collected in the filter cavity.

[0115] As part of the inventive concept of this disclosure, before describing the embodiments of this disclosure, it is necessary to analyze the reasons for the difficulty in cleaning foreign objects collected by the foreign object filter in the washing machine in related technologies, and obtain the technical solution of the embodiments of this disclosure through reasonable analysis.

[0116] In related technologies, washing machines are clothing processing devices that convert electrical energy into mechanical energy to wash clothes. They are now widely used in households. During the washing process, friction between clothes and between clothes and the washing machine itself can cause foreign objects to fall off and mix into the wash water. When the washing machine finishes washing and drains, these foreign objects are discharged with the water. If the water is drained directly, these foreign objects will accumulate in the washing machine's drain outlet, drain pipe, and floor drain in the home. Accumulation to a certain extent can lead to blockages in the drainage channels, causing a series of problems. Therefore, the common practice is to add a foreign object filter to the washing machine's drainage structure to collect foreign objects contained in the washing machine's drain water, thereby reducing the foreign object content in the discharged wash water. However, due to water pressure and accumulation during drainage, foreign objects often adhere tightly to the filter and cannot be easily removed. Even if the filter is completely inverted so that the inlet faces downwards, it is still difficult to easily remove the foreign objects. In this situation, it is necessary to shake it vigorously, rinse it with tap water, or even manually remove or use tools to clean the foreign objects, which is time-consuming and inconvenient.

[0117] To address this, the present disclosure provides a washing machine that includes a drain filter device. By designing the foreign matter storage section in the drain filter device as an openable and closable split structure, the foreign matter can be easily removed by opening the foreign matter storage section when cleaning, thereby improving the technical problem of difficult-to-clean foreign matter collected in the prior art.

[0118] The technical solutions of the embodiments of this disclosure are described in detail below with reference to the accompanying drawings. The technical features involved in the different embodiments of this disclosure described below can be combined with each other as long as they do not conflict with each other.

[0119] See Figures 1 to 5, Figure 1 A schematic diagram of the internal structure of a washing machine is provided, showing the installation position of the drain filter device 1 in the washing machine. Figures 2 to 5 A structural schematic diagram of the first type of drainage filter device (with the housing removed) in closed and open states at different angles is provided; it shows a specific structure of the sealing part 12 and the foreign matter storage part 13, as well as the process of removing the foreign matter 7.

[0120] An embodiment of this disclosure provides a washing machine including a drain filter 1, which is mounted on the drain path of the washing machine and used to collect foreign objects 7 from the water discharged from the washing machine. Figures 1 to 5 As shown, the drain filter device 1 includes a housing 11, a sealing part 12, and a foreign matter storage part 13; wherein, a receiving cavity 111 is formed inside the housing 11, the receiving cavity 111 has a port, the port being opened on the side of the receiving cavity 111 near the outer end face of the washing machine; the receiving cavity 111 is configured to communicate with the drain path and allow water flowing in the drain path to pass through; the sealing part 12 is detachably installed on the port to open or close the receiving cavity 111; the foreign matter storage part 13 is connected to one end of the sealing part 12 and can be placed inside the receiving cavity 111.

[0121] In this embodiment, as Figure 1 As shown, the housing 11 is constructed as the outer shell of the drainage filter device 1, and is usually a rectangular hollow structure. The cavity 111 inside can accommodate the foreign matter storage section 13. During the process of water passing through the cavity 111 in the drainage path, the foreign matter storage section 13 can filter the foreign matter 7 contained in the water and retain the foreign matter 7 in the foreign matter storage section 13 without affecting the flow of water.

[0122] Since the drainage path is generally located at the bottom of the washing machine, the housing 11 can be located inside the bottom side of the washing machine to be connected to the drainage path, and can be extended from the outer end face of the washing machine toward the inside of the washing machine. The port of the receiving cavity 111 is located on the side close to the outer end face of the washing machine, so that the foreign object storage part 13 can be easily placed into or taken out of the receiving cavity 111 through the port, and the sealing part 12 is installed on the port of the receiving cavity 111.

[0123] The outer end face of the washing machine can be the front end face, the rear end face, or the side end face located between the front end face and the rear end face. To facilitate the retrieval and placement of foreign objects in the foreign object storage section 13, the port of the receiving cavity 111 can usually be located on the side close to the front end face of the washing machine.

[0124] In this embodiment, as Figure 1As shown, the sealing part 12 can carry the foreign object storage part 13 and place it into the receiving cavity 111. Then, the sealing part 12 can be used to seal the port of the receiving cavity 111. A sealing structure 121 can also be provided on the sealing part 12. The sealing structure 121 can achieve a seal between the sealing part 12 and the port, and can prevent water flowing through the receiving cavity 111 from flowing out from the port.

[0125] Optionally, such as Figures 2 to 5 As shown, the sealing structure 121 can be a sealing ring sleeved on the sealing part 12. When the sealing part 12 is installed on the port of the receiving cavity 111, the sealing ring can be located between the sealing part 12 and the port to achieve a seal between the two.

[0126] Alternatively, the connection between the sealing part 12 and the port can be a snap-fit, a threaded connection, or the like.

[0127] In this embodiment, as Figures 2 to 5 As shown, the foreign matter storage unit 13 includes an openable and closable first split structure 131 and a second split structure 132. The first split structure 131 has a first connecting end and a first end wall disposed opposite to each other along a first direction. The second split structure 132 has a second connecting end and a second end wall disposed opposite to each other along the first direction. The first connecting end is fixedly connected to the sealing part 12, and the second connecting end is movably connected to the first connecting end via a shaft 133. That is, in the foreign matter storage unit 13, the first split structure 131 is fixedly connected to the sealing part 12, and the second split structure 132 can rotate around the shaft 133 to realize the opening and closing between the first split structure 131 and the second split structure 132. The second split structure 132 can be connected to the sealing part 12 through a movable connection with the first split structure 131.

[0128] It should be understood that in the foreign matter storage section 13, the second split structure 132 can also be fixedly connected to the sealing section 12, and the first split structure 131 can be movably connected to the second split structure 132; that is, the second connecting end is fixedly connected to the sealing section 12, and the first connecting end is movably connected to the second connecting end through the shaft 133. In this technical solution, the first split structure 131 needs to rotate around the shaft 133 to realize the opening and closing between the first split structure 131 and the second split structure 132, and the first split structure 131 is connected to the sealing section 12 through the movable connection with the second split structure 132.

[0129] For ease of description, this embodiment is illustrated by taking the example of the first split structure 131 being fixedly connected to the sealing part 12, and the second split structure 132 being movably connected to the first split structure 131 via the shaft 133.

[0130] The first direction can be the direction in which the foreign object storage section 13 enters or exits relative to the receiving cavity 111.

[0131] Based on the above structure, the first split structure 131 and the second split structure 132 can have a closed state and an open state.

[0132] like Figure 2 and Figure 4 As shown, the closed state is configured such that the second split structure 132 rotates about the axis 133, causing at least a portion of the first end wall 1313 to contact the second end wall 1323.

[0133] In the closed state, a filter chamber 134 is formed between the first split structure 131 and the second split structure 132. An opening is formed at the top of the filter chamber 134, which is configured as the water inlet of the filter chamber 134. Water in the drainage path can enter the filter chamber 134 through the water inlet.

[0134] At least one of the first split structure 131 and the second split structure 132 is provided with a filter channel. When water enters the filter chamber 134, the filter channel can retain at least part of the foreign matter 7 contained in the water in the filter chamber 134 to achieve the filtration of foreign matter 7 in the water. The filter channel can also discharge the water in the filter chamber 134 into the receiving chamber 111, and the discharged water can be discharged from the receiving chamber 111 under the guidance of the drainage path.

[0135] It should be noted that when the foreign object storage section 13 is placed into the receiving cavity 111, the first split structure 131 and the second split structure 132 are in a closed state, so that the filter cavity 134 formed by the first split structure 131 and the second split structure 132 can effectively filter the foreign objects 7 in the water.

[0136] It should be understood that there are several ways to keep the first split structure 131 and the second split structure 132 in a closed state. One way is to utilize the cooperation between the foreign object storage section 13 and the receiving cavity 111; for example, during the process of inserting the foreign object storage section 13 into the receiving cavity 111, the inner wall of the receiving cavity 111 can restrict the outer wall of the foreign object storage section 13, so that the first split structure 131 and the second split structure 132 approach each other and are in a closed state. Another way is to add an external structure; for example, the elastic element 14, the locking mechanism, etc. mentioned below, the added external structure can drive or lock the first split structure 131 and the second split structure 132 and keep them in a closed state.

[0137] like Figure 3 and Figure 5 As shown, the open state is configured such that the second split structure 132 rotates about the axis 133, causing the second end wall 1323 to move away from the first end wall 1313. This process can open the filter chamber 134 to facilitate the removal of foreign objects 7 from the chamber.

[0138] It should be noted that, according to design requirements or due to structural design limitations, the rotation angle of the second split structure 132 relative to the first split structure 131 is subject to certain restrictions. When the second end wall 1323 rotates to its maximum position away from the first end wall 1313, the filter chamber 134 is in a fully open state. At this time, the included angle formed between the first split structure 131 and the second split structure 132 is the maximum rotation angle, and this maximum rotation angle is greater than 0°.

[0139] Optionally, the maximum rotation angle includes, but is not limited to, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, and 60°.

[0140] It should be understood that the open state is for the purpose of facilitating the removal of foreign objects 7 from the foreign object storage section 13. Therefore, it is generally necessary to keep the first split structure 131 and the second split structure 132 in the open state only when the foreign object storage section 13 is removed from the receiving cavity 111.

[0141] In the above technical solution, the foreign matter storage section 13 is divided into two openable and closable structures, namely a first split structure 131 and a second split structure 132, and the top of the filter cavity 134 formed by these two structures also has an opening. When the foreign matter storage section 13 is removed and the foreign matter 7 inside is cleaned, by opening the first split structure 131 and the second split structure 132, the filter cavity 134 formed by these two structures can be opened to loosen the foreign matter 7 and reduce the adhesion strength of the foreign matter 7 on the foreign matter storage section 13. At the same time, the opening can be made to face downwards, and under the action of gravity, the foreign matter 7 can fall out of the filter cavity 134 through the opening, thus achieving the effect of easily removing the foreign matter collected in the filter cavity 134. Figure 5 As shown.

[0142] See Figure 2 and Figure 3 , Figure 2 and Figure 3 A structural schematic diagram of the first type of drainage filter device (without the housing) in both closed and open states is provided; a specific structure of the first split structure 131 and the second split structure 132 is shown.

[0143] In some embodiments, such as Figure 2 and Figure 3As shown, the first split structure 131 includes a first bottom wall 1311, a first side wall 1312, and a first end wall 1313. The first bottom wall 1311 extends along a first direction. The first side wall 1312 is connected to the end of the first bottom wall 1311 away from the second split structure 132. The first end wall 1313 is connected to the end of the first bottom wall 1311 away from the sealing part 12. The first side wall 1312 and the first end wall 1313 are connected to each other and both surround the top of the first bottom wall 1311. The end of the first side wall 1312 away from the first end wall 1313 can be connected to the end face of the sealing part 12.

[0144] The second split structure 132 includes a second bottom wall 1321, a second side wall 1322, and a second end wall 1323. The second bottom wall 1321 extends along a first direction. The second side wall 1322 is connected to the end of the second bottom wall 1321 away from the first split structure 131. The second end wall 1323 is connected to the end of the second bottom wall 1321 away from the sealing part 12. The second side wall 1322 and the second end wall 1323 are connected to each other and both surround the top of the second bottom wall 1321. The end of the second side wall 1322 away from the second end wall 1323 can be movably connected to the end of the first side wall 1312 away from the first end wall 1313 via a shaft 133.

[0145] In the closed state, the first bottom wall 1311 and the second bottom wall 1321 are joined together along the second direction, the first end wall 1313 and the second end wall 1323 are joined together along the second direction, and the first side wall 1312 and the second side wall 1322 are arranged opposite to each other along the second direction. The first bottom wall 1311, the second bottom wall 1321, the first end wall 1313, the second end wall 1323, the first side wall 1312 and the second side wall 1322 together form a filter cavity 134 with an opening at the top.

[0146] The second direction can be the arrangement direction of the first bottom wall 1311 and the second bottom wall 1321 in the closed state.

[0147] In the above technical solution, both the first split structure 131 and the second split structure 132 adopt a structural design in which the bottom wall, side wall and end wall are connected. In the closed state, the two bottom walls (i.e. the first bottom wall 1311 and the second bottom wall 1321) are connected, and the two side walls (i.e. the first side wall 1312 and the second side wall 1322) and the two end walls (i.e. the first end wall 1313 and the second end wall 1323) are arranged around the upper outer periphery of the two bottom walls. They can also cooperate with the end face of the sealing part 12, and thus together form a filter cavity 134, and the top of the filter cavity 134 can form an opening. When cleaning foreign objects, the first split structure 131 and the second split structure 132 are opened, which can separate the two bottom walls, the two side walls and the two end walls. The foreign objects attached to the bottom wall, side wall and end wall can be pulled during the opening process, thus loosening or directly detaching from the bottom wall, side wall and end wall, which can achieve the effect of facilitating the cleaning of foreign objects 7.

[0148] To facilitate the removal of foreign objects 7, the foreign object storage section 13 is divided into a first split structure 131 and a second split structure 132 that can be opened and closed. The first split structure 131 and the second split structure 132 can be movably connected via a hinge shaft 133. This movable structure allows for easy removal of the foreign object 7 from the storage section 13. Although this movable structure can be opened and closed, the operation is relatively complex, requiring manual closure after opening. To solve this problem, the following solution can be adopted.

[0149] See Figure 6 and Figure 7 , Figure 6 and Figure 7 A schematic diagram of the second type of drainage filter device (without housing) in closed and open states is provided; it shows a scheme in which an elastic member 14 is provided between the sealing part 12 and the foreign matter storage part 13.

[0150] In some embodiments, such as Figure 6 and Figure 7 As shown, an elastic element 14 is provided between the second split structure 132 and the sealing part 12; the elastic element 14 is configured to drive the second split structure 132 to rotate around the axis 133, and to enable the first split structure 131 and the second split structure 132 to be in a closed state.

[0151] Optionally, the elastic element 14 can be an elastic sheet, a spring, etc.

[0152] Furthermore, a connecting plate 13221 is provided at one end of the second sidewall 1322 near the sealing part 12; an installation space is provided between the side of the connecting plate 13221 away from the filter chamber 134 and the end face of the sealing part 12 facing the foreign matter storage part 13; the installation space is configured to accommodate the elastic member 14 and enable the elastic member 14 to be connected between the connecting plate 13221 and the sealing part 12.

[0153] In the above technical solution, an elastic element 14 is provided between the second split structure 132 and the sealing part 12. The elastic element 14 can be used to drive the second split structure 132 to rotate around the axis 133 and realize the automatic closure of the second split structure 132 and the first split structure 131 without manual closure, which simplifies the operation of opening and closing the foreign object storage part 13. Moreover, the design of the elastic element 14 can keep the first split structure 131 and the second split structure 132 in a closed state when they are placed in the receiving cavity 111.

[0154] Furthermore, a toggle member 15 is provided at the end of the connecting plate 13221 away from the sealing part 12, and the toggle member 15 protrudes from the side of the connecting plate 13221 away from the filter chamber 134.

[0155] Optionally, the toggle element 15 is integrally formed with the connecting plate 13221.

[0156] The actuating element 15 is configured to drive the second split structure 132 to rotate about the axis 133 by actuating the actuating element 15, and to compress the elastic element 14 within the installation space so that the first split structure 131 and the second split structure 132 can be in the open state.

[0157] In the above technical solution, by setting a toggle member 15 on the second split structure 132, the toggle member 15 can be used to squeeze the elastic member 14 to open the foreign object storage section 13, so that the first split structure 131 and the second split structure 132 are in the open state; moreover, the toggle member 15 protrudes from the connecting plate 13221, which facilitates the opening operation and helps guide the user to perform the pressing operation.

[0158] When the foreign object storage section 13 is placed into the receiving cavity 111, it is necessary to ensure that the first split structure 131 and the second split structure 132 are in a closed state. If the first split structure 131 and the second split structure 132 are opened too easily, the foreign object may fall out of the filter cavity 134 at any time, causing the filter cavity 134 to fail to filter the foreign object. To solve this problem, the following solution can be adopted.

[0159] See Figures 8 to 11 , Figure 8 and Figure 10 A structural diagram of a third type of drainage filter device (without the housing) in both closed and open states is provided; Figure 9 for Figure 8 Enlarged schematic diagram of the central locking mechanism; Figure 11 for Figure 10 An enlarged schematic diagram of the locking mechanism shows a specific structure of the locking mechanism, namely a snap-fit ​​structure, which also acts together with the elastic element 14 on the foreign object storage section 13.

[0160] In some embodiments, a locking mechanism is provided between the first end wall 1313 and the second end wall 1323. The locking mechanism is configured to lock the first end wall 1313 and the second end wall 1323 in the closed state, which can prevent the first split structure 131 and the second split structure 132 from opening and closing at will.

[0161] For example, such as Figures 8 to 11 As shown, one specific structure of the locking mechanism can be a snap-fit ​​structure, which includes an elastic snap-fit ​​element 16 and a snap-fit ​​groove; one of the first end wall 1313 and the second end wall 1323 is connected to the elastic snap-fit ​​element 16, and the other is provided with a snap-fit ​​groove; in the closed state, the elastic snap-fit ​​element 16 engages with the snap-fit ​​groove to lock the first end wall 1313 and the second end wall 1323.

[0162] Optionally, the slot can be provided separately, or the filter channel formed on the first end wall 1313 or the second end wall 1323 can be used as the slot for engaging with the elastic card 16.

[0163] For example, another specific structure of the locking mechanism can be a magnet structure (not shown in the figure), which includes a first magnet and a second magnet; one of the first end wall 1313 and the second end wall 1323 is provided with the first magnet, and the other is provided with the second magnet; in the closed state, the first magnet and the second magnet are arranged opposite to each other and attract each other to lock the first end wall 1313 and the second end wall 1323.

[0164] Optionally, in the closed state, the first magnet and the second magnet may be disposed on opposite surfaces of the first end wall 1313 and the second end wall 1323 in the second direction.

[0165] Optionally, the number of the first magnet and the number of the second magnet can be kept the same and the quantity can be set as needed.

[0166] It should be noted that the snap-fit ​​structure is at risk of breakage and damage during long-term use. Therefore, a magnetic structure can be used instead of the snap-fit ​​structure to achieve the same locking effect; or, the magnetic structure can be used in conjunction with the snap-fit ​​structure to lock the first end wall 1313 and the second end wall 1323 together, preventing the first split structure 131 and the second split structure 132 from opening and closing arbitrarily when closed.

[0167] In the above technical solution, a locking mechanism is provided between the first end wall 1313 and the second end wall 1323. The locking mechanism can lock the first end wall 1313 and the second end wall 1323 to ensure that after the foreign matter storage part 13 is placed in the receiving cavity 111, the first split structure 131 and the second split structure 132 can remain in a closed state, preventing the filter cavity 134 from failing to effectively filter foreign matter due to the opening of the first split structure 131 and the second split structure 132.

[0168] It should be noted that the locking mechanism in this embodiment can work together with the elastic element 14 in the above embodiment to act on the foreign object storage part 13, so as to improve the stability of the first split structure 131 and the second split structure 132 in the closed state.

[0169] Considering that users may forget to lock the foreign object storage section 13 using the locking mechanism and directly insert it into the receiving cavity 111, the first split structure 131 and the second split structure 132 may not be fully closed, thus failing to effectively filter foreign objects. To solve this problem, the following solution can be adopted.

[0170] See Figures 12 to 15 , Figure 12 and Figure 13 A structural diagram of the fourth type of drainage filter device (without the housing) in both closed and open states is provided; a specific structure of the first protrusion structure 17 and the second protrusion structure 18 is shown. Figure 14 and Figure 15 A partial top view of the fourth type of drainage filtration device is provided, showing the fit between the first protruding structure, the second protruding structure, and the recessed structure.

[0171] In some embodiments, such as Figure 12 and Figure 13 As shown, a first protrusion structure 17 is provided on the side of the first end wall 1313 facing away from the filter cavity 134; a second protrusion structure 18 is provided on the side of the second end wall 1323 facing away from the filter cavity 134. Figure 14 and Figure 15 As shown, a recessed structure 114 is provided at the end of the housing 11 opposite to the port.

[0172] When the foreign object storage section 13 is placed in the receiving cavity 111, the first protruding structure 17 and the second protruding structure 18 can be inserted together into the recessed structure 114. Under the restriction of the recessed structure 114, the first protruding structure 17 and the second protruding structure 18 move closer to each other in the second direction to keep the first split structure 131 and the second split structure 132 in a closed state.

[0173] Optionally, a chamfer structure can be provided at the entrance of the recessed structure 114, which can guide the first protruding structure 17 and the second protruding structure 18 into the recessed structure 114.

[0174] In the above technical solution, the cooperation between the first protruding structure 17, the second protruding structure 18 and the recessed structure 114 can limit the distance between the first split structure 131 and the second split structure 132 in the second direction, thereby ensuring that after the foreign object storage part 13 is placed in the receiving cavity 111, the first split structure 131 and the second split structure 132 can automatically close and remain closed.

[0175] It should be noted that the mating structure of the first protruding structure 17, the second protruding structure 18 and the recessed structure 114 in this embodiment can work together with the elastic element 14 and / or the locking mechanism in the above embodiments to act on the foreign matter storage part 13, so as to further improve the stability of the first split structure 131 and the second split structure 132 in the closed state.

[0176] Typically, a filter channel is installed on the bottom wall of the foreign matter storage section 13, and this filter channel is generally designed with a mesh structure. However, long, dirty foreign objects such as hair can easily become entangled in the mesh structure and are difficult to clean. To solve this problem, the following solution can be adopted.

[0177] See Figure 16 and Figure 17 , Figure 16 and Figure 17 A structural diagram of the fifth type of drainage filter device (without the housing) in both closed and open states is provided; it shows a specific structure in which the first comb tooth structure 13111 and the second comb tooth structure 13211 cooperate.

[0178] In some embodiments, such as Figure 16 and Figure 17 As shown, a first comb tooth structure 13111 is formed on the first bottom wall 1311, and a second comb tooth structure 13211 is formed on the second bottom wall 1321; in the closed state, the first comb tooth structure 13111 and the second comb tooth structure 13211 are staggered, and a gap is formed between the first comb tooth structure 13111 and the second comb tooth structure 13211.

[0179] In the above technical solution, a first comb tooth structure 13111 and a second comb tooth structure 13211 that can be staggered are designed between the first bottom wall 1311 and the second bottom wall 1321, replacing the closed mesh structure. When it is necessary to clean foreign objects, the first split structure 131 and the second split structure 132 can be opened to separate the first comb tooth structure 13111 and the second comb tooth structure 13211. Foreign objects attached to the first comb tooth structure 13111 and the second comb tooth structure 13211 can be easily detached along the direction of the comb teeth, and there will be no problem of difficulty in cleaning due to foreign objects entangled in the first comb tooth structure 13111 and the second comb tooth structure 13211. Moreover, the gap between the first comb tooth structure 13111 and the second comb tooth structure 13211 can be used as a filter channel to improve the drainage capacity of the filter chamber 134.

[0180] See Figure 16 , Figure 16 A schematic diagram of the fifth type of drainage filtration device (without the housing) in the closed state is provided; it shows the specific structure of the filtration channels at different locations of the foreign matter storage section 13.

[0181] In some embodiments, the filter channel is one or a combination of a grid structure, a mesh structure, and a comb structure.

[0182] For example, filter channels are provided on the first bottom wall 1311, the second bottom wall 1321, the first end wall 1313, the second end wall 1323, the first side wall 1312 and the second side wall 1322 to improve the drainage capacity of the filter chamber 134.

[0183] Optionally, the filter channels on the first bottom wall 1311 and the second bottom wall 1321 can be designed as a comb structure, and the filter channels on the first end wall 1313, the second end wall 1323, the first side wall 1312 and the second side wall 1322 can be designed as a grid structure.

[0184] In the above technical solutions, the filter channel can adopt one structure or a combination of multiple structures, and the optimal one can be selected according to design requirements.

[0185] The embodiments of this disclosure also provide a washing machine, which includes a drain filter device mounted on the drain path of the washing machine for collecting foreign objects in the water discharged from the washing machine. The main difference between this embodiment and the embodiments described above is that the first and second split structures in the foreign object storage section can be movably connected to the sealing section separately, that is, the first connecting end and the second connecting end are movably connected to the sealing section via a shaft.

[0186] Specifically, the drainage filtration device includes a housing, a sealing section, and a foreign matter storage section.

[0187] The housing has an internal cavity with a port located on the side of the cavity near the outer end face of the washing machine. The cavity is configured to connect to a drain path and allow water flowing in the drain path to pass through.

[0188] The sealing part is detachably installed at the port to open or close the receiving cavity.

[0189] The foreign matter storage unit is connected to one end of the sealing unit and can be placed into the receiving cavity. The foreign matter storage unit includes a first split structure and a second split structure.

[0190] The first split structure has a first connecting end and a first end wall arranged opposite to each other along a first direction; the second split structure has a second connecting end and a second end wall arranged opposite to each other along a first direction; the first connecting end and the second connecting end are movably connected to the sealing part by a shaft.

[0191] Based on this structure, the first split structure and the second split structure have a closed state and an open state.

[0192] In the closed state, at least one of the first and second split structures is configured to rotate about an axis, causing the first end wall to at least partially contact the second end wall. In the closed state, a filter chamber is formed between the first and second split structures, and an opening is formed at the top of the filter chamber, which is configured as the water inlet of the filter chamber. A filter channel is provided on at least one of the first and second split structures, and the filter channel is configured to retain at least a portion of the foreign matter contained in the water in the filter chamber and to allow the water in the filter chamber to be discharged. When the foreign matter storage part is placed in the receiving cavity, the first and second split structures are in the closed state.

[0193] The open state is configured such that at least one of the first split structure and the second split structure rotates about an axis, causing the first end wall and the second end wall to move away from each other, thereby opening the filter chamber.

[0194] The main differences between this embodiment and the embodiments described above will be explained below. The relevant technical solutions of the embodiments described above that can be directly applied to this embodiment will not be repeated here.

[0195] When the foreign matter storage section is placed into the receiving cavity, the first and second split structures must remain closed in order to effectively filter the foreign matter contained in the water.

[0196] Therefore, one structural design between the foreign matter storage section and the sealing section is as follows: elastic elements are respectively provided between the first split structure and the sealing section and between the second split structure and the sealing section, and the two elastic elements can jointly drive the first split structure and the second split structure to close automatically.

[0197] Another structural design between the foreign matter storage section and the sealing section can be: an elastic element is provided between the sealing section and one of the first split structure and the second split structure, and a locking mechanism is provided between the first split structure and the second split structure; wherein, the elastic element can keep the foreign matter storage section and the sealing section in a relatively fixed state, and the locking mechanism can ensure that the first split structure and the second split structure are in a closed state.

[0198] In the above technical solution, the first and second split structures of the foreign matter storage section can be independently and movably connected to the sealing part via shafts, making the foreign matter storage section a two-part structure that can be opened and closed. The top of the filter cavity formed by these two parts also has an opening. When the foreign matter storage section is removed and the foreign matter inside is cleaned, the filter cavity formed by these two parts can be opened by opening the first and second split structures to loosen the foreign matter and reduce its adhesion strength on the foreign matter storage section. At the same time, the opening can face downwards, and under the action of gravity, the foreign matter can fall out of the filter cavity through the opening, thus achieving the effect of easily removing the foreign matter collected in the filter cavity.

[0199] See Figure 1 , Figure 1 A schematic diagram of the internal structure of a washing machine is provided; it shows the structural components of the washing machine and the installation position of the drain filter device 1 in the washing machine.

[0200] This disclosure provides another washing machine, including any one or more drainage filtration devices 1 from the above embodiments.

[0201] like Figure 1 As shown, the washing machine also includes a cabinet 2, a washing drum 3, and a drainage path. The washing drum 3 is disposed inside the cabinet 2 and is used for washing clothes. The drainage path is divided into a first drainage path 4 and a second drainage path 5. The first drainage path 4 is configured to guide water in the washing drum 3 into the receiving cavity 111, and the second drainage path 5 is configured to drain water from the receiving cavity 111. It should be understood that the second drainage path 5 can directly drain water to the outside of the cabinet 2, or the second drainage path 5 can also drain water into the washing machine's circulation pipe or equipment as needed, using the water as circulating water to continue washing clothes.

[0202] In the drainage filtration device 1, its receiving cavity 111 has an inlet 112 and an outlet 113; the inlet 112 is configured to connect to the first drainage path 4 and guide the water flowing in the first drainage path 4 from the inlet into the filtration cavity 134; the outlet 113 is configured to connect to the second drainage path 5 and guide the water discharged from the filtration cavity 134 into the second drainage path 5.

[0203] Optionally, a drain valve 6 is provided on the second drainage path 5, and the drainage filter device 1 is located upstream of the drain valve 6, which can filter the water entering the drain valve 6 first to avoid clogging the drain valve 6.

[0204] Optionally, the washing machine includes, but is not limited to, front-loading washer-dryer combos, front-loading washing machines, and top-loading washing machines.

[0205] In the above technical solution, the washing machine includes the drain filter device 1 of any of the above embodiments. The washing machine can achieve the same technical effect as the drain filter device 1, which will not be described in detail here.

[0206] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and not to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure, and they should all be covered within the scope of the claims and specification of this disclosure.
