[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0033] The following is for reference. Figures 1-8 A filter assembly 100 according to a first aspect embodiment of the present invention is described.

[0034] like Figures 1-5 As shown, the filter assembly 100 according to the first aspect of the present invention includes: a filter structure 10 and an indicator mechanism 20.

[0035] The prompting mechanism 20 is connected to the filter structure 10. The prompting mechanism 20 has a contact portion 221 that is movable relative to the filter structure 10 between an initial position and an installed position. In the vertical direction of the filter structure 10, the installed position is located above the initial position, and the prompting mechanism 20 is configured to move the contact portion 221 from the initial position to the installed position under the push of an external force.

[0036] It should be noted that when the filter assembly 100 is correctly installed on the dishwasher, the filter structure 10 of the filter assembly 100 can effectively remove food residue and other impurities during the dishwasher's cleaning process, keeping the water flow clean and thus ensuring the cleaning effect of the dishes. In a specific example, such as Figure 1 and Figure 2 As shown, the dishwasher has a base 200 at its bottom, and the filter assembly 100 is snapped onto the base 200, meaning the filter assembly 100 is detachably connected to the dishwasher. Figures 5-8As shown, the indicator mechanism 20 is snapped onto the lower side of the filter structure 10, meaning that the indicator mechanism 20 is detachably connected to the filter structure 10. This effectively improves the convenience and efficiency of maintaining the filter assembly 100.

[0037] Furthermore, the contact portion 221 of the prompting mechanism 20 is located on the lower side of the prompting mechanism 20. In the vertical direction, the installed position is above the initial position relative to the filter structure 10. When the filter assembly 100 is not installed on the dishwasher or is not properly installed on the dishwasher, the contact portion 221 of the prompting mechanism 20 is located in the initial position or between the initial position and the installed position. When the user installs the filter assembly 100 on the base 200 of the dishwasher, the contact portion 221 of the prompting mechanism 20 can move upward relative to the filter structure 10 from the initial position to the installed position under the push of an external force. That is, the filter structure 10 can move downward relative to the prompting mechanism 20. When the user removes the filter assembly 100 from the base 200 of the dishwasher, the contact portion 221 of the prompting mechanism 20 can move relative to the filter structure 10 from the installed position to the initial position. That is, the filter structure 10 can move upward relative to the prompting mechanism 20.

[0038] In this embodiment, when the user installs the filter assembly 100 on the dishwasher base 200, the filter assembly 100 is first placed on the dishwasher base 200, thus completing the initial installation of the filter assembly 100. Then, the user applies external force to the filter assembly 100, causing the contact portion 221 of the prompting mechanism 20 to move upward relative to the filter structure 10 from its initial position to its installed position under the push of the external force; that is, the filter structure 10 can move downward relative to the prompting mechanism 20. This allows the entire filter assembly 100 to be installed in place on the dishwasher base 200.

[0039] In other words, when installing the filter assembly 100, the user needs to actively apply external force to ensure that the filter assembly 100 is installed in place. If the filter assembly 100 is not installed in place on the dishwasher base 200 due to improper operation by the user or insufficient external force, the user can directly observe or perceive that the filter assembly 100 is not installed in place. This can effectively remind the user and thus effectively prevent the filter assembly 100 from being improperly installed on the dishwasher base 200.

[0040] According to the filter assembly 100 of this utility model embodiment, by providing a filter structure 10 and a prompting mechanism 20 in the filter assembly 100, the prompting mechanism 20 is connected to the filter structure 10 and has a contact portion 221. The contact portion 221 is movable relative to the filter structure 10 between an initial position and an installed position. In the vertical direction, the installed position is located above the initial position, and the prompting mechanism 20 is configured to move the contact portion 221 from the initial position to the installed position under the push of an external force. This can effectively remind the user whether the filter assembly 100 is installed correctly when the user installs the filter assembly 100 on the dishwasher, avoiding the filter assembly 100 being improperly installed and affecting the washing effect of the dishwasher, thereby effectively improving reliability and enhancing the user experience.

[0041] In one embodiment of this utility model, such as Figures 4-8 As shown, the prompting mechanism 20 includes an elastic element 21, which is configured to elastically deform under the action of an external force, thereby moving the contact portion 221 to the installed position. In a specific example, such as Figure 4 As shown, the elastic element 21 is a spring, and more specifically, the elastic element 21 is a compression spring.

[0042] In other words, the elastic element 21 can always drive the contact portion 221 of the prompting mechanism 20 to move relative to the filter structure 10 toward the initial position. When the user installs the filter assembly 100 on the base 200 of the dishwasher, an external force needs to be applied to the elastic element 21 of the prompting mechanism 20. When the external force applied by the user to the elastic element 21 of the prompting mechanism 20 is greater than or equal to the elastic force of the elastic element 21 in the initial position, the elastic element 21 will undergo elastic deformation, that is, the spring will be compressed. At this time, if the user continues to apply external force to the elastic element 21, the contact portion 221 can be gradually moved to the installation position, thereby allowing the entire filter assembly 100 to be installed in place on the base 200 of the dishwasher.

[0043] When the user removes the filter assembly 100 from the base 200 of the dishwasher, the contact portion 221 of the prompting mechanism 20 moves relative to the filter structure 10 toward the initial position under the elastic force of the elastic member 21 and eventually moves to the initial position. This avoids the user having to manually return the contact portion 221 of the prompting mechanism 20 to the initial position.

[0044] This embodiment provides an elastic element 21 in the prompting mechanism 20. The elastic element 21 is configured to undergo elastic deformation under the action of external force, so that the contact part 221 moves to the installed position. This not only effectively simplifies the structure of the prompting mechanism 20, thereby effectively reducing costs, but also facilitates user operation, thereby effectively improving the convenience of user operation.

[0045] In one embodiment of this utility model, such as Figure 2 , Figure 6 and Figure 8 As shown, the lower end of the elastic member 21 is formed as a contact portion 221, or the lower end of the elastic member 21 is connected to the contact portion 221; and / or, a downwardly extending positioning post 111 is formed at the bottom of the filter structure 10, and the upper end of the elastic member 21 is sleeved on the positioning post 111.

[0046] For example, the lower end of the elastic member 21 is formed as a contact portion 221, that is, the lower end of the elastic member 21 can move between the initial position and the installed position relative to the filter structure 10 under the push of an external force. As a result, the number of parts can be reduced, thereby effectively simplifying the structure of the prompting mechanism 20.

[0047] For example, the lower end of the elastic member 21 is connected to the contact portion 221. For instance, the lower end of the elastic member 21 abuts against the contact portion 221. That is to say, the lower end of the elastic member 21 and the contact portion 221 can move between the initial position and the installed position relative to the filter structure 10 under the push of external force. The contact portion 221 can effectively prevent external force from acting directly on the lower end of the elastic member 21, thereby forming an effective protection for the lower end of the elastic member 21.

[0048] In a specific example, such as Figure 6 and Figure 8 As shown, the elastic element 21 is a spring, and the lower end of the spring abuts against the upper side of the contact portion 221. Furthermore, the lower end of the spring is fixedly connected to the upper side of the contact portion 221, which can effectively prevent the spring from shifting or moving during elastic deformation, thereby effectively improving the reliability of spring deformation.

[0049] In this embodiment, by forming the lower end of the elastic element 21 into a contact portion 221, the number of parts can be effectively reduced, thereby simplifying the structure of the prompting mechanism 20 and reducing costs. By connecting the lower end of the elastic element 21 to the contact portion 221, the elastic element 21 can be effectively protected, preventing it from being directly subjected to external forces, thereby improving the durability of the elastic element 21.

[0050] In a specific example, such as Figure 2 As shown, the positioning post 111 is a ring-shaped rib extending in the vertical direction. The upper end of the positioning post 111 is connected to the bottom of the filter structure 10, and the lower end of the positioning post 111 extends downward, with the upper end of the elastic member 21 sleeved on the positioning post 111, thereby effectively fixing the elastic member 21. Furthermore, the positioning post 111 and the filter structure 10 are integrally formed, which ensures the reliability of the connection between the positioning post 111 and the filter structure 10 and effectively simplifies the assembly process.

[0051] When the elastic element 21 undergoes elastic deformation, the elastic element 21 can be stretched or compressed in the vertical direction relative to the filter structure 10 between the initial position and the installed position under the push of an external force. In other words, the contact part 221 can move in the vertical direction relative to the filter structure 10 between the initial position and the installed position under the push of an external force.

[0052] Therefore, it is possible to effectively prevent the elastic element 21 from shifting or falling off during elastic deformation, thereby effectively preventing the contact part 221 from shifting during movement. Furthermore, the positioning post 111 provides a fixed and clearly defined mounting point for the elastic element 21, facilitating its positioning and assembly. In a specific example, such as... Figure 2 As shown, the upper end of the elastic member 21 abuts against the bottom of the filter structure 10. Furthermore, the upper end of the elastic member 21 is fixedly connected to the bottom of the filter structure 10, thereby further fixing the elastic member 21.

[0053] In this embodiment, a downwardly extending positioning post 111 is formed at the bottom of the filter structure 10, and the upper end of the elastic member 21 is sleeved on the positioning post 111. This not only effectively improves the reliability and stability of the prompting mechanism 20, but also facilitates the assembly of the elastic member 21, thereby effectively improving the convenience of assembly.

[0054] In one embodiment of this utility model, the elastic deformation direction of the elastic member 21 is the vertical direction of the filter structure 10, and the elastic force of the elastic member 21 is greater than the weight of the filter structure 10. By setting the elastic deformation direction of the elastic member 21 to the vertical direction of the filter structure 10, and ensuring that the elastic force of the elastic member 21 is greater than the weight of the filter structure 10, this embodiment enables the elastic member 21 to lift the filter structure 10 when the user has not installed the filter assembly 100 properly, thereby effectively reminding the user and ensuring the reliability of the reminder function.

[0055] In one embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the prompting mechanism 20 also includes: a cover 22, which is located on the lower side of the filter structure 10 and together with the filter structure 10 defines the mounting cavity 220; an elastic member 21 is located in the mounting cavity 220; the lower end of the elastic member 21 is connected to the cover 22; and the lower end of the cover 22 is formed as a contact portion 221.

[0056] In a specific example, such as Figure 2 and Figure 4As shown, the lower end of the elastic member 21 abuts against the upper side of the contact portion 221. Furthermore, an upwardly extending sidewall 222 is formed around the periphery of the contact portion 221. The sidewall 222 of the cover 22 and the contact portion 221 can together with the filter structure 10 to form a mounting cavity 220 for mounting the elastic member 21, thereby preventing external factors from interfering with or damaging the elastic member 21.

[0057] In this embodiment, a cover 22 is provided in the prompting mechanism 20. The cover 22 is located below the filter structure 10 and together with the filter structure 10 defines the mounting cavity 220. An elastic member 21 is located in the mounting cavity 220, and the lower end of the elastic member 21 is connected to the cover 22. The lower end of the cover 22 is formed as a contact portion 221. This not only allows the cover 22 to provide a reliable mounting space for the elastic member 21, but also allows the cover 22 to effectively protect the elastic member 21, thereby effectively improving the durability of the elastic member 21 and thus effectively improving the service life of the prompting mechanism 20.

[0058] In one embodiment of this utility model, such as Figure 2 As shown, the bottom of the filter structure 10 has a downwardly extending guide rib 112. The guide rib 112 extends in a ring shape along the circumference of the elastic member 21. The cover 22 is formed as a cylindrical shape with an open top. The cover 22 is fitted on the radial outside of the guide rib 112 and can slide relative to the guide rib 112 in the up and down direction.

[0059] In a specific example, such as Figure 2 As shown, the guide rib 112 is an annular rib extending in the vertical direction, and the upper end of the elastic member 21 is located radially inside the guide rib 112. The sidewall 222 of the cover 22 is sleeved on the outer side of the guide rib 112. When the elastic member 21 undergoes elastic deformation, the cover 22 can slide relative to the guide rib 112 in the vertical direction. Furthermore, the guide rib 112 is integrally formed with the filter structure 10, and the length of the guide rib 112 in the vertical direction is consistent with that of the positioning post 111. This ensures the reliability of the connection between the guide rib 112 and the filter structure 10 and effectively simplifies the assembly process.

[0060] In other words, the guide rib 112 can effectively guide the cover 22 to move in the vertical direction, preventing the cover 22 from shifting or tilting during movement, thereby effectively ensuring the stability and reliability of the contact part 221 between its initial position and its installed position. In addition, the guide rib 112 can provide a fixed and clear mounting point for the cover 22, thus facilitating the positioning and assembly of the cover 22.

[0061] In this embodiment, a downwardly extending guide rib 112 is formed at the bottom of the filter structure 10. The guide rib 112 extends in a ring shape along the circumference of the elastic member 21. The cover 22 is formed into a cylindrical shape with an open top. The cover 22 is sleeved on the radial outside of the guide rib 112 and can slide relative to the guide rib 112 in the up and down direction. This not only effectively ensures the stability and reliability of the cover 22, but also facilitates the assembly of the cover 22, thereby effectively improving the assembly efficiency.

[0062] In one embodiment of this utility model, such as Figures 2-4 As shown, one of the filter structure 10 and the cover 22 is provided with a hook 223 and the other is provided with a hole. The hook 223 passes through the hole and is movable in the vertical direction relative to the hole. In the initial position, the hook part 2231 of the hook 223 abuts against the periphery of the hole in the vertical direction.

[0063] For example, the filter structure 10 has a hook 223, and the cover 22 has a locking hole; or, for example, the filter structure 10 has a locking hole, and the cover 22 has a hook 223. In a specific example, such as Figures 2-4 As shown, the filter structure 10 is provided with a locking hole, and the cover 22 is provided with a hook 223. Specifically, the bottom of the filter structure 10 is provided with a locking hole that extends through the bottom of the filter structure 10 in the vertical direction, and the upper end of the side wall 222 of the cover 22 is provided with a hook 223. Furthermore, when the prompting mechanism 20 and the filter structure 10 are assembled together, the hook portion 2231 of the hook 223 is located above the locking hole.

[0064] like Figure 2 As shown, when the contact portion 221 of the cover 22 moves toward the side away from the filter structure 10 relative to the filter structure 10, the hook portion 2231 of the hook 223 can move downward relative to the locking hole. When the contact portion 221 of the cover 22 moves to the initial position under the elastic force of the elastic member 21, the hook portion 2231 of the hook 223 abuts against the periphery of the locking hole in the vertical direction. That is to say, at this time, the cover 22 of the prompting mechanism 20 is locked at the bottom of the filter structure 10 under the elastic force of the elastic member 21. Thus, the cover 22 can be restricted from continuing to move away from the filter structure 10.

[0065] In this embodiment, a hook 223 is provided on one of the filter structure 10 and the cover 22, and a hole is provided on the other. The hook 223 passes through the hole and is movable in the vertical direction relative to the hole. In the initial position, the hook portion 2231 of the hook 223 abuts against the periphery of the hole in the vertical direction, which can effectively improve the stability and reliability of the connection between the filter structure 10 and the cover 22.

[0066] In one embodiment of this utility model, such as Figures 2-4As shown, the hook 223 extends vertically, and a perforated hole 2230 is formed on the hook 223, extending through the hook 223 along its thickness direction. The perforated hole 2230 extends vertically, and its upper end extends to the area where the hook portion 2231 is located, so that the hook portion 2231 can be elastically deformable. In the width direction of the hook 223, at least a portion of the width dimension of the hook portion 2231 is larger than the dimension of the hole. For example, the width dimension of part of the hook portion 2231 is larger than the dimension of the hole; or, for example, the width of all parts of the hook portion 2231 is larger than the dimension of the hole. In a specific example, such as Figures 2-4 As shown, the width of part 2231 is greater than the size of the card hole.

[0067] When the cover 22 and the filter structure 10 are assembled together, the hook portion 2231 of the hook 223 of the cover 22 can pass through the bottom hole of the filter structure 10 from bottom to top through its own elastic deformation, thereby quickly assembling the cover 22 to the bottom of the filter structure 10. Specifically, when the hook portion 2231 of the hook 223 passes through the bottom hole of the filter structure 10, the hook portion 2231 of the hook 223 can change its width under the action of external force, so that the width of the hook portion 2231 of the hook 223 is smaller than the width of the hole, thereby allowing the hook portion 2231 of the hook 223 to pass smoothly through the hole.

[0068] In this embodiment, the hook 223 is configured to extend in the vertical direction, and a hollow hole 2230 is formed on the hook 223, which extends through the hook 223 along the thickness direction of the hook 223. The hollow hole 2230 extends vertically, and the upper end of the hollow hole 2230 extends to the area where the hook portion 2231 is located, so that the hook portion 2231 can be elastically deformed. In the width direction of the hook 223, at least part of the width dimension of the hook portion 2231 is larger than the size of the hole. This not only effectively simplifies the structural construction of the hook 223, but also simplifies the assembly process between the cover 22 and the filter structure 10, thereby effectively improving the assembly efficiency.

[0069] In one embodiment of this utility model, such as Figures 2-4 As shown, there are multiple hooks 223, which are arranged at intervals along the circumference of the cover 22. There are also multiple locking holes, each corresponding one-to-one with a hook 223. For example, the number of hooks 223 can be two, three, four, five, or more than six. In a specific example, such as... Figure 4 As shown, there are two hooks 223, and the two hooks 223 are symmetrically arranged along the circumference of the cover 22.

[0070] In this embodiment, by setting the number of hooks 223 to multiple, the multiple hooks 223 are arranged at intervals along the circumference of the cover 22, and the number of holes is multiple and corresponds one-to-one with the multiple hooks 223, the force on the periphery of the hooks 223 and holes is uniform, avoiding stress concentration on the periphery of the hooks 223 and holes, thereby effectively improving the reliability and durability of the connection between the filter structure 10 and the cover 22.

[0071] In one embodiment of this utility model, such as Figures 1-8 As shown, the filter structure 10 includes: a cylindrical filter element 11, a planar filter element 12, and a cup 13.

[0072] The cylindrical filter element 11 is a hollow column extending vertically; the planar filter element 12 is arranged on the upper side of the cylindrical filter element 11, and a through hole is formed on the planar filter element 12 that runs vertically through the planar filter element 12; the cup 13 is arranged on the upper side of the planar filter element 12, and the lower end of the cup 13 extends into the cylindrical filter element 11 through the through hole and is fixedly connected to the cylindrical filter element 11; the prompting mechanism 20 is located at the bottom of the cylindrical filter element 11.

[0073] Specifically, such as Figure 1 and Figure 2 As shown, an annular limiting rib 131 extending circumferentially along the upper outer periphery of the cup 13 is provided. The limiting rib 131 can abut against the wall of the through hole to restrict the movement between the cup 13 and the planar filter element 12. Figure 5 and Figure 7 As shown, the upper end of the cup 13 is provided with a downwardly protruding locking block 132, and the upper end of the cylindrical filter element 11 is provided with a mounting hole, into which the locking block 132 can be inserted. The bottom of the cylindrical filter element 11 is provided with a locking hole, into which the hook 223 of the cover 22 can be inserted.

[0074] When assembling the cylindrical filter element 11, the planar filter element 12, and the cup 13 together, first insert the lower end of the cup 13 through the through hole into the cylindrical filter element 11, and then insert the locking block 132 into the mounting hole. That is, the planar filter element 12 is located between the cup 13 and the cylindrical filter element 11, and the cup 13 and the cylindrical filter element 11 are locked together. In this way, the assembly of the cylindrical filter element 11, the planar filter element 12, and the cup 13 can be completed.

[0076] In this embodiment, a cylindrical filter element 11, a planar filter element 12, and a cup 13 are provided in the filter structure 10. The cylindrical filter element 11 is a hollow column extending vertically. The planar filter element 12 is arranged on the upper side of the cylindrical filter element 11 and has a through hole that runs vertically through it. The cup 13 is arranged on the upper side of the planar filter element 12, and its lower end extends through the through hole into the cylindrical filter element 11 and is fixedly connected to it. The prompting mechanism 20 is located at the bottom of the cylindrical filter element 11, which can effectively enhance the filtration effect of the filter structure 10.

[0077] A dishwasher according to a second aspect embodiment of the present invention includes a water cup 300 and a filter assembly 100 according to the first aspect embodiment of the present invention described above. The filter assembly 100 is snap-fitted to the water cup 300, and the prompting mechanism 20 is configured such that when the filter assembly 100 is snap-fitted to the water cup 300, the contact portion 221 moves from an initial position to an installed position.

[0078] In a specific example, such as Figure 3 As shown, a plurality of first snap-fit ​​blocks 133 are arranged at intervals on the outer peripheral surface of the bottom of the cup 13, and a plurality of second snap-fit ​​blocks are provided inside the water cup 300. The first snap-fit ​​blocks 133 and the second snap-fit ​​blocks correspond one to one, and the first snap-fit ​​blocks 133 and the second snap-fit ​​blocks can be snapped together, so that the filter component 100 can be snapped onto the water cup 300.

[0079] When the user installs the filter assembly 100 on the dishwasher base 200, the filter assembly 100 is first placed on the dishwasher base 200 to complete the initial installation of the filter assembly 100. Then, by rotating and pressing the cup 13, the first locking block 133 and the second locking block can be locked together. At this time, the contact part 221 moves from the initial position to the installed position relative to the filter structure 10 under the push of external force, thereby completing the installation of the filter assembly 100. When the user removes the filter assembly 100, they only need to rotate the filter assembly 100 to separate the first locking block 133 from the second locking block, thereby enabling quick removal of the filter assembly 100.

[0080] According to the present invention, the dishwasher, by providing the filter component 100 of the first aspect, can effectively remind the user whether the filter component 100 is installed in place when the user installs it on the dishwasher, thus avoiding the filter component 100 being improperly installed and affecting the washing effect of the dishwasher, thereby effectively improving reliability and enhancing the user experience.
