[0035] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present disclosure.

[0036] Moreover, the disclosure can repeat reference numerals and / or letters in the various examples, which repetition is for the purpose of simplicity and clarity and does not prefer one described embodiment of the disclosure over another and is not intended to limit the scope of the disclosure or claims thereof.

The appearances of the phrase "in one embodiment" or "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, and the use of the expressions "in one embodiment" or "in an embodiment" in various place of the specification in no way excludes that there are various alternative implementations with each one of the features and / or combinations of the features mentioned in each embodiment or that the features can be implemented other than is specified in each embodiments. Furthermore, the term "comprising" does not exclude the presence of elements or steps other than those listed and the term "comprising" makes it clear that, when used, whether special approved terms such as "consisting essentially of" or "consisting of" are used, only the specified features of the disclosure are essential in the implementation of the present disclosure.

[0038] Moreover, the disclosure can repeat reference numerals and / or letters in the various examples, which repetition is for the purpose of simplicity and clarity and does not prefer one described embodiment of the disclosure over another and is not intended to limit the scope of the disclosure or claims thereof.

[0039] In a first aspect, the disclosure provides a filtering device capable of automatically cleaning the filter, so as to solve the problem that the filtering device is easy to be blocked and the manual cleaning is time-consuming and laborious to some extent.

[0040] The filtering device provided by the present disclosure comprises a filtering housing, a filtering element and a cleaning element. The filtering housing is provided with a filtering cavity, a water inlet and a water outlet which are communicated with the filtering cavity. The filtering cavity can be in a shape of a cylinder, a sphere, a prism or the like, and can also be in a shape of a plane or a curved surface. The filtering cavity can be used to accommodate the filtering element. The water inlet is communicated with the filtering cavity, so that the fluid medium can enter the filtering cavity through the water inlet. The water outlet is communicated with the filtering cavity, so that the fluid medium in the filtering cavity can be discharged from the water outlet. The filtering element is arranged in the filtering cavity to filter the fluid medium flowing through the filtering element. The filtering element is in a shape matched with the filtering cavity, and the gap therebetween is arranged in the filtering cavity. The filtering element can be provided with a grid-shaped filtering hole on the peripheral side. The filtering hole of the filtering element is easy to be blocked by food residues, oil stains and other foreign matters. Once blocked, the filtering hole needs to be cleaned manually, which is time-consuming and laborious.

[0041] In an embodiment, the water inlet can be directed to the peripheral side of the filtering element, and the water outlet can be directed to the axial end of the filtering element, so that the fluid medium flows from the outer periphery of the filtering element to the inside, and then is discharged from the axial end of the filtering element. In another embodiment, the water inlet can be directed to the axial end of the filtering element, and the water outlet can be directed to the peripheral side of the filtering element, so that the fluid medium enters the filtering element from the axial end and then moves to the outside of the filtering element through the filtering hole. Alternatively, the water inlet and the water outlet can be both directed to the peripheral side of the filtering element. The water inlet and the water outlet can be located on both sides of the filtering element, or can be arranged at an angle on the outside of the filtering element, so that the fluid medium flows from one side of the filtering element to the other side of the filtering element through the filtering element.

[0042] In an embodiment, the cleaning element is arranged in the filtering element, and the filtering element and the cleaning element rotate relative to each other. In the process of relative rotation, the cleaning element sweeps the inner surface of the filtering element, so that the residues and foreign matters on the filtering element are separated from the filtering element, thereby alleviating the problem of blocking of the filtering element to a certain extent. In another embodiment, the cleaning element is arranged outside the filtering element, and the filtering element and the cleaning element rotate relative to each other. In the process of relative rotation, the cleaning element sweeps the outer surface of the filtering element, so that the residues and foreign matters on the filtering element are separated from the filtering element, thereby alleviating the problem of blocking of the filtering element to a certain extent. Alternatively, the cleaning element is arranged on the inner and outer surfaces of the filtering element, and the filtering element and the cleaning element rotate relative to each other. In the process of relative rotation, the cleaning element sweeps the inner and outer surfaces of the filtering element, so that the residues and foreign matters on the filtering element are separated from the filtering element, thereby alleviating the problem of blocking of the filtering element to a certain extent.

[0043] In an embodiment, the filtering element is fixed relative to the filtering housing, and the cleaning element rotates relative to the filtering housing, so that the cleaning element in rotation cleans the filtering element in a stationary state, thereby alleviating the problem of blocking of the filtering element to a certain extent. In another embodiment, the cleaning element is fixed relative to the filtering housing, and the filtering element rotates relative to the filtering housing, so that the cleaning element in a stationary state cleans the filtering element in rotation, and the problem of blocking of the filtering element can also be alleviated to a certain extent.

[0044] Fig. 1 to Fig. 12 show a filtering device of an embodiment, which can be defined as a first filtering device 100, in which a filtering housing is defined as a first filtering housing 101, a cleaning member is defined as a first cleaning member 103, a filtering member is defined as a first filtering member 102, a filtering cavity is defined as a first filtering cavity 104, the first cleaning member 103 is disposed outside the first filtering member 102, and the first cleaning member 103 is fixed relative to the first filtering housing 101, and the first filtering member 102 rotates relative to the first filtering housing 101. For the filtering device of other forms in which the filtering member rotates relative to the cleaning member, the first filtering device 100 can be adjusted and designed accordingly, and thus will not be described herein.

[0045] Fig. 1 shows a structural schematic diagram of the first filtering device, and Fig. 2 shows an exploded schematic diagram of Fig. 1. In combination with Fig. 1 and Fig. 2, the periphery of the first filtering housing 101 can be provided with one or more water inlets 105, and the end of the first filtering housing 101 is provided with a water outlet 106, and the water inlets 105 and the water outlet 106 are in communication with the first filtering cavity 104, and the fluid medium flows into the first filtering cavity 104 from the water inlets 105, is filtered by the first filtering member 102, and is discharged from the water outlet 106. For example, in combination with Fig. 1 and Fig. 2, the periphery of the first filtering housing 101 can be provided with two or more water inlets 105, so as to provide multiple water inlets 105 to deliver more medium to the first filtering cavity 104, so as to improve the filtering capacity of the first filtering device 100. In other embodiments, the periphery of the first filtering housing 101 can also be provided with more water inlets 105, which will not be limited herein.

[0046] Figure 3 shows a front view of Figure 1, and Figure 4 shows a cross-sectional view of A-A of Figure 3. In combination with Figures 1-4, in one embodiment, the axis of the water inlet 105 and the axis of the first filter 102 do not intersect, so that the fluid medium entering the first filter 102 through the water inlet 105 of the first filter housing 101 does not flow through the center axis of the first filter 102, but flows along the wall surface of the first filter 102, thereby flushing the circumference of the first filter 102, increasing the path and time of the fluid medium flowing on the first filter 102, improving the filtering effect, and also cleaning the foreign matter on the first filter 102 to some extent, alleviating the phenomenon of the filter holes on the first filter 102 being blocked. In combination with Figure 1, the water inlet direction of the water inlet 105 is preferably arranged along the tangential direction of the peripheral surface of the first filter housing 101, so that the fluid medium entering the first filter 102 through the water inlet 105 of the first filter housing 101 flows in a spiral manner along the wall surface of the first filter 102, thereby flushing the circumference of the first filter 102, increasing the path and time of the fluid medium flowing on the first filter 102, improving the filtering effect, and also cleaning the foreign matter on the first filter 102 to some extent, alleviating the phenomenon of the filter holes on the first filter 102 being blocked. According to another embodiment of the present disclosure, the axis of the water inlet 105 and the axis of the first filter 102 intersect, i.e. the water inlet direction of the water inlet 105 is perpendicular to the axial direction of the first filter 102, which can also achieve the effect of filtering the fluid medium.

[0047] In combination with Figures 1-4, since the first filter 102 and the first cleaning member 103 are both arranged in the first filter cavity 104 of the first filter housing 101, in order to facilitate the assembly of the first filter 102 and the first cleaning member 103 in the first filter cavity 104, the first filter housing 101 can be connected by two single structures, which can be the first housing 1011 and the second housing 1012, respectively. The first housing 1011 and the second housing 1012 can be connected by screws or / and clamping, to form the first filter cavity 104. In order to improve the sealing between the first housing 1011 and the second housing 1012, a first sealing member 1013 is arranged between the first housing 1011 and the second housing 1012, which can be an X-shaped or O-shaped sealing ring.

[0048] Figure 5 shows a structural diagram of the first cleaning member in Figure 1. In combination with Figure 5, the first cleaning member 103 comprises a first cleaning frame 1031 and a first cleaning brush 1032. The first cleaning frame 1031 is disposed outside the first filter member 102, and the first cleaning brush 1032 is connected to the first cleaning frame 1031 on the side of the first cleaning frame 1031 facing the first filter member 102, that is, the first cleaning brush 1032 is located between the first cleaning frame 1031 and the first filter member 102, and the first cleaning frame 1031 is connected to the first filter cavity 104. Since the first cleaning frame 1031 is disposed outside the first filter member 102, the first cleaning frame 1031 is a circumferential surface extending structure to wrap the first filter member 102. In a specific implementation, the first cleaning brush 1032 is clamped or / and bonded to the first cleaning frame 1031, and the first cleaning brush 1032 can be provided in multiple numbers, for example, two, three, or four, etc. The multiple first cleaning brushes 1032 are distributed at intervals, and under the condition that the first filter member 102 rotates one cycle, the same part of the first filter member 102 can be cleaned by the multiple first cleaning brushes 1032, thereby improving the cleaning effect of the first filter member 102.

[0049] In combination with Figure 5, in a specific implementation, the first cleaning frame 1031 can be a frame structure matching the shape of the first filter member 102, which comprises multiple first ring body structures 10311 arranged at intervals along the axial direction, and the multiple ring body structures are connected by connecting columns 10312. The inner side of each connecting column 10312 can be provided with the above-mentioned first cleaning brush 1032.

In combination with Figures 4-7, the first cleaning frame 1031 is clamped to the first filter cavity 104. In a specific implementation, as shown in Figure 5, the end of the first cleaning frame 1031 is provided with multiple first protrusions 1033 at intervals, as shown in Figures 6 and 7, the inner side of the end of the first filter cavity 104 (the first shell 1011 and the second shell 1012) is provided with first notches 1041 matching the first protrusions 1033, as shown in Figure 4, the first protrusions 1033 are inserted into the corresponding first notches 1041 to fix the first cleaning frame 1031 in the first filter cavity 104. In another embodiment, the end of the first cleaning frame 1031 is provided with multiple first notches 1041 at intervals, and the inner side of the end of the first filter cavity 104 is provided with first protrusions 1033 matching the notches, and the first protrusions 1033 are inserted into the corresponding first notches 1041, which can also fix the first cleaning frame 1031 in the first filter cavity 104.

[0051] Figure 8 shows a structural schematic diagram of the first filter element in Figure 1. In combination with Figure 8, the first filter element 102 has a positioning end 1021 and a connecting end 1022 arranged oppositely, wherein the positioning end 1021 of the first filter element 102 is rotatably connected to one end inside the first filter cavity 104, and the connecting end 1022 of the first filter element 102 is used to connect with the first driving element 107, so as to drive the first filter element 102 to rotate in the first filter cavity 104 under the driving of the first driving element 107. The specific assembly mode of the first filter element 102 in the first filter cavity 104 will be further described by means of the drawings.

[0052] In combination with Figure 6, one end of the first filter cavity 104 is provided with a limiting groove 1042, and the positioning end 1021 of the first filter element 102 is rotatably arranged in the limiting groove 1042. The limiting groove 1042 is a ring-shaped groove coaxial with the first filter element 102, and the positioning end 1021 of the first filter element 102 is arranged in the limiting groove 1042 in a clearance, so that the first filter element 102 can rotate relative to the filter housing 101 under the driving of the first driving element 107. In a specific implementation, the end of the first filter cavity 104 is provided with a first limiting ring 110, and the first limiting ring 110 is configured as the above-mentioned limiting groove 1042 with the side wall of the filter cavity.

[0053] In an embodiment, the first driving element 107 can be a driving motor, and the first driving element 107 has a rotatable output end, and the output end of the first driving element 107 is connected with the first filter element 102 to drive the first filter element 102 to rotate relative to the first cleaning element 103.

[0054] In combination with Figures 1-4, in an embodiment, the first driving element 107 is located outside the filter housing 101, does not occupy the installation space of the first filter element 102 and the flow-through space of the fluid medium, and can also avoid the influence of the fluid medium on the operation of the driving motor. In a specific implementation, the output end of the first driving element 107 is connected with a first driving shaft 108, the first driving shaft 108 extends into the first filter cavity 104 and is connected with the connecting end 1022 of the first filter element 102, so as to drive the first filter element 102 to rotate relative to the first cleaning element 103 under the driving of the first driving element 107. In another embodiment, the first driving element 107 can also be located inside the first filter housing 101, but a sealing space needs to be arranged to place the first driving element 107. The specific details of the connection and assembly of the first driving element 107 with the first filter element 102 will be further described by means of the drawings.

[0055] Referring to Figures 2, 4, and 8, the connecting end 1022 of the first filter element 102 is provided with a connection port 1023. The first filter device 100 also includes a mounting member 109, which is assembled within the connection port 1023 and connected to the first drive shaft 108. When the first drive member 107 is activated, it sequentially drives the first drive shaft 108 and the mounting member 109 to rotate, thereby driving the first filter element 102 to rotate. The mounting member 109 provides a mounting base for the first filter element 102, and it can also be assembled with the first drive shaft 108 to achieve connection and assembly between the first drive shaft 108 and the first filter element 102.

[0056] Referring to Figure 8, in a specific implementation, the connecting end 1022 of the first filter element 102 is provided with a connecting portion 1024, and the mounting port is provided within the connecting portion 1024. Figure 9 shows a structural schematic diagram of the mounting component in Figure 1. Referring to Figure 9, the mounting component 109 is provided with a head and a tail along the axial direction of the first drive component 107. The head of the mounting component 109 is connected to the connecting port 1023 of the connecting portion 1024, and the first drive shaft 108 of the first drive component 107 is connected to the tail of the mounting component 109, so that the first drive component 107 and the first filter element 102 are connected and assembled through the transition of the mounting component 109.

[0057] Referring to Figure 9, a support portion 1091 is provided on the periphery of the head of the mounting member 109, and at least a portion of the plane of the connecting portion 1024 is in contact with the support portion 1091. The connecting portion 1024 can be a connecting ring located inside the first filter element 102. The inner ring of the connecting ring forms a connecting port 1023. The support portion 1091 at the head of the mounting member 109 is a supporting ring surface, and the end face of the connecting ring is in contact with the supporting ring surface, so that the mounting member 109 supports the first filter element 102. In another embodiment, the periphery of the mounting member 109 can be provided with multiple levels of annular steps, such as three-level or four-level annular steps. One of the step surfaces of the multiple levels of annular steps forms a supporting ring surface that is in contact with the connecting ring, and one of the remaining step surfaces of the multiple levels of annular steps abuts against the connecting end 1022 of the first filter element 102.

[0058] Referring to Figure 9, in one embodiment, the head of the mounting member 109 may be conical to form a guide structure on its periphery, facilitating the assembly of the mounting member 109 with the first filter element 102. In another embodiment, the head of the mounting member 109 may also be cylindrical.

[0059] Referring to Figures 8 and 9, the connecting portion 1024 and the head of the mounting member 109 are engaged peripherally. In one embodiment, the connecting portion 1024 may have a plurality of second notches 1025 spaced around its central axis, and the head of the mounting member 109 has a plurality of second protrusions 1092. The second protrusions 1092 and the second notches 1025 are correspondingly arranged, and the second protrusions 1092 are inserted into the corresponding second notches 1025 to achieve the engagement of the head of the connecting portion 1024 and the mounting member 109. In another embodiment, the second notches 1025 may also be provided on the head of the mounting member 109, and the second protrusions 1092 may be provided on the connecting portion 1024, which also achieves the assembly of the mounting member 109 with the connecting portion 1024.

[0060] Figure 10 shows a structural schematic diagram from another perspective of Figure 9, and Figure 11 shows a structural schematic diagram of the first drive shaft in Figure 1. Referring to Figures 10 and 11, the tail of the mounting member 109 is provided with a connecting groove 1093, and the first drive shaft 108 is connected within the connecting groove 1093. The cross-section of the portion of the first drive shaft 108 connected to the connecting groove 1093 is a non-circular structure. For example, the cross-section of the portion of the first drive shaft 108 extending into the connecting groove 1093 is cross-shaped, triangular prism, quadrangular prism, or flower-shaped, etc. The shape of the connecting groove 1093 matches the non-circular structure of the first drive shaft 108, so that the first drive shaft 108 can rotate synchronously with the mounting member 109.

[0061] Referring to Figure 11, the first drive shaft 108 is provided with a stepped structure. The top of the stepped structure is a first limiting surface 1081.

The two first limiting rings 110 have different radial dimensions. The two first limiting rings 110 and the inner wall of the first housing 1011 form a limiting groove 1042 for accommodating the positioning end 1021 of the first filter element 102. The limiting ring located on the outer side forms a first mounting groove 111 with the inner wall of the first housing 1011 to accommodate the end of the first cleaning frame 1031, so as to perform rough positioning of the first cleaning frame 1031 during assembly. The bottom of the first mounting groove 111 is provided with a structure for engaging with the first cleaning frame 1031. After rough positioning, it is engaged with the first cleaning frame 1031.

[0063] Referring to Figure 4, the second housing 1012 is provided with a second limiting ring 112. The bottom outer peripheral surface of the mounting member 109 abuts against the inner ring surface of the second limiting ring 112.

In another embodiment, a plurality of fourth protrusions 2016 are spaced apart on the third ring structure 2033 on the periphery of the top of the second filter element 203, and a plurality of fourth notches 2034 are spaced apart on the bottom of the cover 2012. The plurality of fourth protrusions 2016 are inserted into the corresponding fourth notches 2034, and the top of the second filter element 203 can also be connected to the bottom of the cover 2012.

[0070] Figure 17 shows a schematic diagram of the structure of the second cleaning component in Figure 13. Referring to Figure 17, the second cleaning component 202 includes a second cleaning frame 2021 and a second cleaning brush 2022. The second cleaning frame 2021 is placed inside the second filter element 203. The second cleaning brush 2022 can be connected to the periphery of the second cleaning frame 2021 facing the second filter element 203 by snap-fit ​​or adhesive. Multiple second cleaning brushes 2022 can be provided, such as two, three, or four, and these brushes are spaced apart. When the second cleaning component 202 rotates once, the same part of the second filter element 203 can be cleaned by multiple second cleaning brushes 2022, improving the cleaning effect on the second filter element 203.

[0071] Referring to Figure 17, in one embodiment, the second cleaning frame 2021 of the second cleaning member 202 can extend along the radial direction of the second filter member 203, and the central axis of the second cleaning frame 2021 and the second filter member 203 are coaxially arranged. According to another embodiment of the present disclosure, the second cleaning frame 2021 of the second cleaning member 202 can also be a columnar structure, which is coaxially arranged with the second filter member 203.

[0072] Referring to Figure 13, the second filter device 200 also includes a second drive member 204, and a second cleaning member 202 is connected to the second drive member 204 to drive the second cleaning member 202 to rotate inside the second filter member 203 to clean foreign objects on the filter holes of the second filter member 203.

[0073] Referring to Figure 13, consistent with the first filter device 100, the second drive component 204 of the second filter device 200 can also be a drive motor, which is located below the bottom of the main housing 2011. The output end of the second drive component 204 can enter the main housing 2011 through the second drive shaft 205 and be connected to the second cleaning frame 2021.

[0074] Referring to Figure 17, in a specific implementation, the second cleaning frame 2021 is provided with a connecting recess 2023, and the second drive shaft 205 is connected to the connecting recess 2023. The cross-section of the part of the second drive shaft 205 that connects to the connecting recess 2023 is a non-circular structure. For example, the cross-section of the part of the second drive shaft that extends into the connecting recess 2023 is cross-shaped, triangular prism, quadrangular prism, or flower-shaped. The shape of the connecting recess 2023 matches the non-circular structure of the first drive shaft 108 so that the second cleaning frame 2021 rotates synchronously with the second drive shaft. For details, please refer to the connection method of the drive shaft of the first filter device 100, which will not be elaborated here.

[0075] Referring to Figure 16, the inner side of the cover 2012 is provided with a limiting hole 2017. The top of the second cleaning frame 2021 can be rotatably connected to the limiting hole 2017 through the connecting shaft 2024. During the process of the second driving member 204 driving the second cleaning member 202 to rotate, the connecting shaft also rotates accordingly in the limiting hole 2017 to improve the smoothness of the rotation of the second cleaning frame 2021.

[0076] The filtration device provided in this disclosure cleans foreign matter on the filter element by controlling the relative rotation of the cleaning element and / or the filter element during the filtration of fluid media, thereby alleviating the technical problem of filter element clogging to a certain extent and improving the smoothness of the fluid medium. It has good practicality.

[0077] A second aspect of this disclosure is to provide an electrical device that includes the aforementioned filtration device.

[0078] Electrical equipment equipped with the aforementioned filtration devices can alleviate the technical problem of filter clogging to a certain extent, thereby improving the smoothness of the fluid flow and demonstrating excellent practicality.

[0079] In one embodiment, the electrical device can be a dishwasher. According to another embodiment of this disclosure, the electrical device can also be other devices requiring the filtration of fluid media, such as a water dispenser, etc., and there is no limitation herein. Taking a dishwasher as an example, the arrangement of the filtration device within the dishwasher will now be described.

[0080] In related technologies, the dishwasher includes an inner tub 300 and a cup body 400. After the dishes are cleaned, the washing pump 500 stops working, and the drain pump 600 drains the water in the cup to the municipal pipe network.

[0081] Since the water collected in the water-containing cavity 401 of the cup body 400 is residual water after cleaning the tableware, the filter holes of the filter device are easily clogged when the residual water is filtered through the filter device, which affects the cleaning effect and cleaning efficiency of the tableware.

[0082] Based on the above-mentioned technical problems, this disclosure provides a water cup assembly. Figure 18 shows a structural schematic diagram of the water cup assembly. Figure 19 shows a side view of Figure 18, Figure 20 shows an exploded view of Figure 18, Figure 21 shows a cross-sectional view (BB) of Figure 18, and Figure 22 shows a structural schematic diagram of the cup body in Figure 18. Referring to Figures 18-22, the water cup assembly includes a cup body 400, an auxiliary filter device 200, and a main filter device 100. The cup body 400 is provided with a water-containing cavity 401, which contains a main cavity 4011 and a water-distributing cavity 4012. The auxiliary filter device 200 is placed in the water-distributing cavity 4012, and the main filter device 100 is connected to both the main cavity 4011 and the auxiliary filter device 200.

[0083] The water cup assembly provided in this disclosure allows residual water after washing dishes to be temporarily stored in the water-containing cavity 401 of the cup body 400. Since the water-containing cavity 401 is divided into a main cavity 4011 and a sub-cavity 4012, and the main cavity 4011 and the sub-cavity 4012 are connected, the washing water entering the main cavity 4011 can flow into the sub-cavity 4012. Because an auxiliary filter device 200 is installed in the sub-cavity 4012, the washing water flowing through the auxiliary filter device 200 in the sub-cavity 4012 can be filtered, improving the cleanliness of the washing water. Since the main filter device 100 is connected to the main cavity 4011, the main filter device 100 can filter the washing water discharged from the main cavity 4011. Under the action of the washing pump 500, the washing water filtered by the auxiliary filter device 200 and the main filter device 100 is transported to the spray arm of the dishwasher to wash the dishes. In actual use, if part of the filter holes of the main filter device 100 is blocked, the auxiliary filter device 200 and the unblocked filter holes of the main filter device 100 can provide enough washing water for the spray arm to avoid affecting the cleaning effect and efficiency of the tableware, which is very practical.

[0084] In one embodiment, the main filter device 100 can be the first filter device 100 described above, and the auxiliary filter device 200 can be the second filter device 200 described above. The relatively rotating cleaning element or filter element cleans foreign objects on the filter element, thus alleviating the technical problem of filter element clogging to a certain extent, improving the smoothness of the medium fluid, ensuring the smooth delivery of washing water, and thereby avoiding affecting the cleaning effect and efficiency of the tableware. When the auxiliary filter device 200 adopts the second filter device 200 described above, the second filter chamber of the second filter housing 201 of the second filter device 200 is a water distribution chamber 4012. In another embodiment, the main filter device 100 and the auxiliary filter device 200 can also adopt other types of filter devices, such as filter devices without cleaning elements, etc., which will not be elaborated here. The specific details of the water cup assembly will now be further described with reference to Figures 22-23.

[0085] Referring to Figure 22, the cup body 400 of the water cup assembly of this disclosure is a container with an open top. A closed container is disposed within the cup body 400. This closed container can be the aforementioned water distribution chamber 4012, or it can be the second filter housing of the second filter device 200. In one embodiment, the water distribution chamber 4012 can be eccentrically disposed with respect to the cup body 400. In another embodiment, the water distribution chamber 4012 can also be concentrically disposed with respect to the cup body 400; no limitation is made here.

[0086] To achieve communication between the main cavity 4011 and the water distribution cavity 4012 within the cup body 400, one or more openings (not shown) can be provided around the water distribution cavity 4012 to connect the main cavity 4011 and the water distribution cavity 4012. This opening is preferably located at the bottom of the water distribution cavity 4012 so that the washing water received by the main cavity 4011 flows into the water distribution cavity 4012, preventing it from remaining at the bottom of the main cavity 4011.

[0087] Figure 23 shows a structural schematic diagram from another perspective of Figure 22. Referring to Figure 23, the cup body 400 also includes a first water outlet 402 and a second water outlet 403. The first water outlet 402 is connected to the main cavity 4011, and the second water outlet 403 is connected to the water distribution cavity 4012. The first water outlet 402 and the second water outlet 403 can be tubular structures and are configured as two water outlet connectors of the cup body 400. Referring to Figure 1, the first filter device 100 has two inlets 105, namely a first inlet 1051 and a second inlet 1052. The first inlet 1051 is connected to the first water outlet 402, allowing the washing water in the main cavity 4011 to directly enter the first filter chamber 104 of the first filter device 100 through the first water outlet 402 and the first inlet 1051, and then be filtered by the first filter element 102 inside before being discharged through the outlet 106. The second inlet 1052 is connected to the second outlet 403. The washing water filtered by the second filter element 203 of the second filter device 200 enters the filter chamber of the first filter housing 101 through the second outlet 403 and the second inlet 1052. In one embodiment, the second inlet 1052 is located at the end of the first filter housing 101 of the first filter device 100. The washing water entering the filter chamber of the first filter housing 101 through the second inlet 1052 does not flow through the filter chamber of the first filter housing 101, but is discharged directly from the outlet 106 at the end of the first filter housing 101 of the first filter device 100. In another embodiment, the second inlet 1052 is disposed on the periphery of the first filter housing 101 of the first filter device 100. Washing water entering the second filter chamber of the first filter housing 101 through the second inlet 1052 undergoes secondary filtration in the first filter housing 101 before being conveyed to the spray arm assembly. Alternatively, the first filter device 100 may not have a second inlet 1052, and the second outlet 403 of the water cup is directly connected to the washing pump 500. Compared to the first filter device 100 without a second inlet 1052, the second filter device 200 with a second inlet 1052 can be connected to the second outlet 403 and the washing pump 500, saving more space.

[0088] Therefore, the washing water after washing the dishes enters the main cavity 4011 of the cup body 400 and is divided into two paths. One path enters the water distribution cavity 4012 from the main cavity 4011, and is then conveyed to the spray arm assembly through the second filter element and the second water outlet 403. The other path exits from the first water outlet 402 of the main cavity 4011, is filtered by the first filter element 102 of the first filter device 100, and is then conveyed to the spray arm assembly. Thus, the cup assembly provided by this disclosure offers two cleaning pathways for supplying washing water to the spray arm assembly, ensuring sufficient washing water for use, thereby improving the cleaning effect and efficiency of the dishes, and possessing excellent practicality.

[0089] Referring to Figure 23, in some embodiments, the cup body 400 is further provided with a third water outlet 404. The third water outlet 404 is connected to the positioning recess 2014 of the water distribution chamber 4012. The third water outlet 404 can also be a tube structure and is configured as the third water outlet connector of the water cup. Correspondingly, referring to Figure 1, the water inlet 105 of the first filter device 100 also includes a third water inlet 1053. The third water inlet 1053 is connected to the third water outlet 404, so that the washing water in the positioning recess 2014 in the water distribution chamber 4012 enters the first filter chamber 104 of the first filter device 100 through the third water outlet 404 and the third water inlet 1053, and is discharged from the water outlet 106 after being filtered by the first filter element 102 inside. This can avoid the phenomenon of washing water collected in the positioning recess 2014 not being able to be discharged, which causes odor, thereby improving cleaning quality and user experience. In addition, the third water outlet 404, the second water outlet 403 and the first water outlet 402 can form three conveying paths, which can ensure the flow rate of washing water and avoid the technical problem of insufficient washing water delivery caused by the clogging of the filter holes of the filter device, thereby improving the cleaning efficiency of the dishwasher.

[0090] In practice, the first water outlet 402 and the third water outlet 404 on the cup body 400 are positioned as close to the bottom of the cup body 400 as possible to draw out residual water from the cup body 400. This avoids the phenomenon of washing water accumulating in the positioning recess 2014 and causing odors, thereby improving cleaning quality and user experience. The second water outlet 403 can be positioned higher to avoid the first water outlet 402 and the third water outlet 404 and to have a certain height difference, making reasonable use of the dishwasher's internal space.

[0091] Referring to Figures 22 and 23, the cup body 400 is also provided with a water inlet 405 and one or more fourth water outlets 406. The water inlet 405 is connected to the output of the washing pump 500 to introduce filtered washing water. The water inlet 405 is connected to the fourth water outlets 406, which are connected to the spray arm assembly. Therefore, under the action of the washing pump 500, the filtered washing water is discharged to the spray arm assembly of the dishwasher through the water inlet 405 and the fourth water outlets 406, where the spray arms spray water to clean the dishes. In one embodiment, there may be two fourth water outlets 406, which are respectively connected to the upper spray arm and the lower spray arm of the spray arm assembly. In another embodiment, there may be three fourth water outlets 406, which are respectively connected to the upper spray arm, the middle spray arm, and the lower spray arm of the spray arm assembly. When multiple fourth water outlets 406 are provided, a connecting cavity (not shown) is also provided on the cup body 400. The connecting cavity is connected to the water inlet 405 and multiple fourth water outlets 406 to distribute the washing water filtered by the water inlet 405 to each of the fourth water outlets 406.

[0092] This disclosure achieves the connection between the washing pump 500 and the spray arm assembly by providing a water inlet 405 and one or more fourth water outlets 406 on the cup body 400, without the need to provide corresponding connecting pipes between the washing pump 500 and the spray arm assembly, resulting in a compact structure and improved space utilization.

[0093] It should be noted that in other embodiments, the washing pump 500 can also be connected to the spray arm assembly through a structure such as a three-way valve, and this is not a limitation.

[0094] In one embodiment, referring to FIG22, the cup body 400 is further provided with a drain cavity 407 and a drain channel 408. The drain cavity 407 is disposed on the periphery of the cup body 400. At least part of the drain pump 600 can be installed in the drain cavity 407. The drain cavity 407 is connected to the interior of the water distribution chamber 4012 through the drain channel 408 to drain the residual water in the cup after the dishes are washed, so that the dishwasher is dry and clean, and foreign objects ferment and produce odors.

[0095] Referring to Figures 22 and 23, the first water outlet 402, the second water outlet 403, the third water outlet 404, and the water inlet 405 are all located on the same side of the cup body 400, facilitating direct connection with the second filter device 200, washing pump 500, etc., eliminating the need for piping, resulting in a compact structure and improved space utilization. The drain chamber 407 is located on the other side of the cup body 400, allowing water circulation and drainage to occur on both sides of the cup body 400, facilitating piping arrangement. The fourth water outlet 406 is located at the top of the cup body 400, facilitating connection with the spray arm assembly above the tableware, saving space. In another embodiment, the drain chamber 407 can also be located on the same side of the cup body 400 as the first water outlet 402, the second water outlet 403, and the third water outlet 404.

[0096] Based on the aforementioned water cup assembly, this disclosure also provides a dishwasher including the aforementioned water cup assembly. The dishwasher with the aforementioned water cup assembly can provide sufficient washing water for the spray arms to avoid affecting the cleaning effect and efficiency of the tableware. Furthermore, the relatively rotating cleaning or filtering elements can clean foreign objects on the filter elements, thus alleviating the technical problem of filter clogging to a certain extent, improving the smoothness of the fluid medium, and ensuring the smooth delivery of washing water to avoid affecting the cleaning effect and efficiency of the tableware, thus possessing excellent practicality.

[0097] Based on the aforementioned water cup assembly, this disclosure also provides a dishwasher water system, which includes a washing pump 500, a drain pump 600, a spray arm assembly 700, and the aforementioned water cup assembly. The main filter device 100 of the water cup assembly is sequentially connected to the washing pump 500 and the spray arm assembly 700, and the drain pump 600 is connected to the water-containing chamber 401. The dishwasher water system with the aforementioned water cup assembly can provide sufficient washing water for the spray arms to avoid affecting the cleaning effect and efficiency of the dishes. Furthermore, the relatively rotating cleaning or filtering components can clean foreign objects on the filter components, alleviating the technical problem of filter clogging to a certain extent, thereby improving the smoothness of the fluid and ensuring the smooth delivery of washing water to avoid affecting the cleaning effect and efficiency of the dishes. This system has excellent practicality.

[0098] The specific workflow of the dishwasher water system provided in this disclosure is as follows:

[0099] When the dishwasher is in operation, the drain pump 600 is turned off. The water used to wash the dishes collects at the bottom of the inner tank 300 and enters the main cavity 4011 of the cup body 400. A portion of the water flows along the first water outlet 402 and the first water inlet 1051 into the first filter device 100. After being filtered by the first filter device 100, the water is output by the washing pump 500 and distributed to each spray arm of the spray arm assembly to clean the dishes. A portion of the water in the main cavity 4011 flows to the water distribution chamber 4012. A portion of the washing water in the water distribution chamber 4012 is filtered by the second filter element 203 and then flows along the second water outlet 403 and the second water inlet 1052 to the second filter device 200. Under the power of the washing pump 500, the water is distributed to each spray arm of the spray arm assembly to clean the dishes.

[0100] After the dishes are cleaned, the drain pump 600 is turned on to discharge the washing water containing contaminants in the main chamber 4011 and the water distribution chamber 4012 of the cup body 400 through the drain channel 408 to the municipal pipe network, so that the dishwasher is dry and clean and to prevent foreign objects from fermenting and producing odors.

[0101] It should be noted that the first filter device 100 and / or the second filter device 200 of this disclosure can be operated at a certain stage of the dishwasher's operation, or after the dishwasher has finished operating, and can be operated by the user through commands.
