Detailed implementation manner

[0030] To make the technical problems solved by this application, the technical solutions adopted, and the achieved technical effects clearer, the following further details the technical solutions of the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this application.

[0031] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0032] In this application, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is at a higher horizontal height than the second feature. The first feature being "below", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature is at a lower horizontal height than the second feature.

[0033] In the water circulation pipeline system of some existing washing machines, a filter box is provided. The filter box can filter out impurities such as cotton fluffs that are likely to cause blockages in the washing water, and then the filtered water is circulated back to the washing drum or discharged. The filter screen in the filter box is a consumable. After being used for a certain period of time, it needs to be removed for cleaning or replacement. Therefore, the filter screen of the existing filter box is generally set as an easily detachable and installable structure. Specifically, the filter box is installed near the washing machine housing, and the sealing cover on the filter box is exposed on the surface of the housing. The sealing cover is generally threadedly installed on the filter box. For the convenience of users to operate, a protruding handle is also provided on the sealing cover, so that users can easily disassemble and install the sealing cover by twisting the handle to complete the cleaning or replacement operation of the filter screen in the filter box. However, the handle protruding from the surface of the washing machine housing will occupy a certain installation space and will affect the placement of the washing machine in some cases; moreover, the protruding handle is also at risk of being broken by external force impact; in addition, the protruding handle will also affect the overall appearance of the washing machine.

[0034] To overcome the above technical problems, referring to Figure 1-8 , this embodiment provides a washing machine filter box, which includes a housing 1, a filter 2 and a sealing cover 3. A filter cavity 11 is formed inside the housing 1, and an installation opening 12 communicating with the filter cavity 11 is formed on one side. The housing 1 is also provided with a water inlet joint 13 and a water outlet joint 14 respectively communicating with the filter cavity 11; the filter 2 can be installed into the filter cavity 11 through the installation opening 12; the sealing cover 3 is threadedly installed on the installation opening 12 to seal the installation opening 12; the sealing cover 3 includes a main cover body 31 and a rotating handle 32. A receiving groove 311 is provided on the outer surface of the main cover body 31, and the rotating handle 32 is rotatably installed in the receiving groove 311. The rotating handle 32 can be switched between an unfolded state and a received state through its own rotation. In the unfolded state, the rotating handle 32 extends out of the receiving groove 311. At this time, the main cover body 31 can be twisted through the rotating handle 32 to disassemble and install the sealing cover 3; in the received state, the rotating handle 32 is embedded in the receiving groove 311, and the outer surface of the rotating handle 32 is flush with the outer surface of the main cover body 31.

[0035] Specifically, in application, the filter 2 is installed in the filter cavity 11 through the installation opening 12, and the installation opening 12 is blocked by the installation of the sealing cover 3; the water inlet joint 13 and the water outlet joint 14 are respectively connected to the water inlet pipe and the water outlet pipe. The washing water in the washing drum is introduced into the filter cavity 11 through the water inlet pipe. After being filtered by the filter 2, it then flows out through the water outlet pipe. The water outlet pipe can be connected to the washing drum to realize the reuse of the filtered water back to the washing drum, or it can be directly connected to the drainage pipe to discharge the filtered water. Filtering the cotton fluffs in the washing water and then discharging it can effectively avoid the problem of drainage pipe blockage.

[0036] The sealing cover 3 is threadedly installed on the installation port 12 of the housing 1, and its disassembly and assembly process is achieved by rotation. Therefore, a rotating handle 32 is provided in this solution. During operation, a person's hand can hold the rotating handle 32 to rotate for disassembly and assembly. Thus, it is convenient for the user to complete the disassembly and assembly of the sealing cover 3 manually.

[0037] A storage groove 311 is provided on the main cover body 31 of the sealing cover 3. The rotating handle 32 is rotatably connected to the main cover body 31, and when the sealing cover 3 is installed, the rotating handle 32 can be rotated and stored in the storage groove 311 so that the rotating handle 32 does not protrude from the surface of the main cover body 31.

[0038] In summary, for the washing machine filter box based on this embodiment, a filter 2 is provided in the housing 1 for filtering the washing water, and a sealing cover 3 is provided to seal the installation port 12 of the housing 1. When it is necessary to clean or replace the filter 2, the sealing cover 3 can be opened to take out the filter 2, and after the filter 2 is reinstalled, the sealing cover 3 can be reinstalled. The sealing cover 3 in this solution is provided with a rotating handle 32, which facilitates the knob operation during the disassembly and assembly of the sealing cover 3. Importantly, a storage groove 311 is provided on the main cover body 31 of the sealing cover 3, and the rotating handle 32 is rotatably installed in the storage groove 311. When operation is required, the rotating handle 32 can be rotated and unfolded for manual operation; after the installation of the sealing cover 3 is completed, the rotating handle 32 is directly rotated and stored in the storage groove 311 so that the rotating handle 32 does not protrude from the outer surface of the main cover body 31, thereby avoiding problems such as the rotating handle 32 occupying the installation space, being easily broken by external force impact, and affecting the appearance of the washing machine.

[0039] In one embodiment, referring to Figure 8 , the main cover body 31 is provided with hinge grooves 312 located on two opposite sides of the storage groove 311. The rotating handle 32 includes a handle body 321 and a rotating shaft 322 passing through the handle body 321. Both ends of the rotating shaft 322 are respectively inserted into the hinge grooves 312 on both sides to achieve the rotational installation of the rotating handle 32.

[0040] As a connecting member between the rotating handle 32 and the main cover body 31, the rotating shaft 322 should be designed to ensure that the handle can rotate smoothly without obstruction, reducing friction and wear. Both ends of the rotating shaft 322 are respectively inserted into the hinge grooves 312 on both sides. This double-point fixing method makes the rotating handle 32 more stable during rotation and not easy to shake or fall off.

[0041] Among them, the rotating shaft 322 is the main connection point between the rotating handle 32 and the main cover body 31 and is the main stress point during the rotation of the user. To ensure the reliability of the rotating shaft 322, it is preferably made of a material with higher strength, such as steel, aluminum alloy, etc.

[0042] In one embodiment, two symmetrically arranged rotary handles 32 are installed on the main cover 31. In the storage state, the storage groove 311 is closed by the two rotary handles 32 together.

[0043] By setting two rotary handles 32, when rotating, the user can hold the two rotary handles 32 simultaneously to rotate. At this time, the holding feel is better, which is more conducive to the user applying force. At the same time, the two rotary handles 32 jointly bear the torque, playing a role in dispersing the acting force and improving the reliability.

[0044] In one embodiment, one hinge groove 312 is provided on each side of the storage groove 311, and the hinge groove 312 is a waist-shaped long groove. The two ends of the rotating shaft 322 of the two rotary handles 32 are respectively inserted into the hinge grooves 312 on both sides, and the rotating shaft 322 can slide along the hinge groove 312 in the unfolded state, so that the two rotary handles 32 after unfolding can slide to a position where they fit together.

[0045] Based on the structure that the rotating shaft 322 can slide relative to the hinge groove 312, after unfolding, the two rotary handles 32 can be slid to a position where they fit together, so that the user can hold the two rotary handles 32 simultaneously with one hand to rotate; when storing, based on the sliding of the rotating shaft 322, the two rotary handles 32 can maintain a certain distance, so that the two handles can respectively rotate to a position where they are stored in the storage groove 311, avoiding the problem of interference between the two rotary handles 32 during the storage process.

[0046] In one embodiment, a first magnetic member is provided inside the main cover 31, and a second magnetic member is correspondingly provided inside the rotary handle 32. In the storage state, the first magnetic member and the second magnetic member are attracted to each other, so that the rotary handle 32 is kept in the storage state.

[0047] When the rotary handle 32 rotates into the storage groove 311 and reaches a predetermined position, the first magnetic member and the second magnetic member are automatically attracted to each other, thereby firmly holding the rotary handle 32 in the storage state. The attractive force of the magnetic member helps to ensure the close fit between the rotary handle 32 and the main cover 31, thereby avoiding the problem of the rotary handle 32 rotating and unfolding freely.

[0048] In one embodiment, a waterproof ring 4 is provided between the sealing cover 3 and the mounting opening 12.

[0049] The main function of the waterproof ring 4 is to fill the tiny gap between the sealing cover 3 and the mounting opening 12, forming an effective waterproof barrier to avoid the problem of water leakage from the mounting opening 12 inside the housing 1.

[0050] In one embodiment, the filter 2 is connected to the sealing cover 3, and the sealing cover 3 can drive the filter 2 in and out of the filtering chamber 11.

[0051] During the process of disassembling and assembling the filter 2, the user does not need to directly operate the filter 2. Instead, the user can indirectly control the entry and exit of the filter 2 by moving the sealing cover 3. This design simplifies the operation process, reduces the complexity and difficulty of user operation, and makes the cleaning and maintenance work easier and faster.

[0052] In one embodiment, the filter 2 is rotatably connected to the sealing cover 3, so that the sealing cover 3 can rotate relative to the filter 2 during the disassembly and assembly process.

[0053] Specifically, since the connection between the sealing cover 3 and the housing 1 is a threaded connection, the disassembly and assembly process requires rotating the sealing cover 3. Connecting the filter 2 and the sealing cover 3 rotatably enables the filter 2 to remain stationary during the rotation of the sealing cover 3 during disassembly and assembly, so that the installed filter 2 can be maintained in the correct working position to achieve effective filtration.

[0054] In one embodiment, the filter 2 includes a filter frame 21 and a filter net (not shown in the figure) detachably installed on the filter frame 21, and the sealing cover 3 is rotatably connected to the filter frame 21.

[0055] The filter frame 21 is provided to provide stable support for the filter net, so that it can be stably maintained in a state where normal filtration can be provided. Adopting the form of combining the filter net and the filter frame 21, when replacing, only the filter net needs to be replaced separately, and the cost of part replacement is lower.

[0056] In one embodiment, referring to Figure 4 , a connection hole 211 is provided on one side of the filter frame 21 close to the sealing cover 3, the sealing cover 3 is provided with a connection buckle 33 corresponding to the connection hole 211, the connection buckle 33 includes a buckle handle 331 and a buckle hook 332 connected to the end of the buckle handle 331, the buckle handle 331 passes through the connection hole 211, and the buckle hook 332 abuts against the inner wall of the filter frame 21 to prevent the connection buckle 33 from detaching from the connection hole 211, thereby realizing the rotational connection between the sealing cover 3 and the filter frame 21.

[0057] Adopting the structure of directly providing the connection buckle 33 on the sealing cover 3 and providing the connection hole 211 on the filter frame 21, so that the connection buckle 33 is buckled with the connection hole 211 to realize the rotational connection structure between the sealing cover 3 and the filter frame 21 has the advantages of simple implementation and low cost. Specifically, the connection buckle 33 can be a structure integrally formed with the main cover body 31.
