[0043] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0044] See also Figures 1 to 10 , an embodiment of the present application provides a stirring device 1 for use in a washing device.

[0045] An embodiment of the present application provides a washing device, including a washing drum, a stirring shaft, and a stirring device 1 of any embodiment of the present application.

[0046] It should be noted that the washing device can be a clothing processing device or a fruit and vegetable cleaning machine, etc. The clothing processing device can be a pulsator washing machine, a washer-dryer, etc., and there is no limitation here.

[0047] The washing drum is used to contain laundry, which may be clothes, fruits and vegetables, etc. The top side of the washing drum is provided with an opening, through which a user can put in or take out laundry.

[0048] Taking the stirring device 1 applied to a clothes processing device as an example, the clothes processing device may only include a washing drum, in which case the washing drum can hold both washing water and clothes; the clothes processing device may also include an outer drum, in which the washing drum is arranged, the outer drum is used to hold washing water, and the inner drum is used to hold clothes. Of course, in some embodiments, the clothes processing device may include a washing drum and an outer drum, in which the washing drum can hold both washing water and clothes, and the water in the washing drum will not enter the outer drum.

[0049] The stirring device 1 is rotatably disposed in the washing tub, and the top end of the stirring shaft is connected to the stirring device 1 .

[0050] It is understandable that when the washing device is in the washing state, the stirring shaft rotates, thereby driving the stirring device 1 to rotate. For example, in some embodiments, the washing device includes a motor and a reducer, and the motor shaft of the motor drives the stirring shaft to rotate through the reducer, thereby driving the stirring device 1 to rotate to achieve washing of the laundry.

[0051] It should be noted that, during the washing process, the stirring device 1 rotates driven by the stirring shaft, and the washing drum may rotate or may not rotate, and there is no limitation here.

[0052] The stirring device 1 includes a stirring wheel 10 , a stirring rod 11 and a filtering unit 12 .

[0053] The stirring wheel 10 can rotate forward or reverse to drive the water flow to rotate forward or reverse, and the laundry is washed through the impact of the water flow and the friction of the laundry itself.

[0054] For some examples, see Figure 7 and Figure 8 The stirring wheel 10 is provided with convex ribs 102. When the stirring wheel 10 rotates, the convex ribs 102 can drive the water flow more efficiently and improve the washing effect.

[0055] See also Figure 7 and Figure 8 The stirring wheel 10 has a mounting top wall 101, and the mounting top wall 101 is provided with a first flow channel hole 101a and a first connecting portion 1011. The first flow channel hole 101a is connected to the bottom area of ​​the stirring wheel 10, that is, water can flow to the bottom area of ​​the stirring wheel 10 through the first flow channel hole 101a.

[0056] It should be noted that the mounting top wall 101 is a structure arranged on the top side of the stirring wheel 10 and used for installation and cooperation with the stirring rod 11. The bottom area of ​​the stirring wheel 10 refers to the space located below the stirring wheel 10 and away from the stirring rod 11. When water flows toward the mounting top wall 101, it flows to the space below the stirring wheel 10 through the first flow channel hole 101a.

[0057] It should be noted that the water flowing to the bottom area of ​​the stirring wheel 10 through the first flow channel hole 101a can return to the washing tub again to wash the laundry.

[0058] The stirring rod 11 is used to dock with the stirring wheel 10 so as to rotate under the drive of the stirring wheel 10 , thereby driving the water flow to rotate.

[0059] In the related art, the washing device only has a stirring wheel, and the rotation of the stirring wheel drives the water flow to rotate so as to wash the laundry. However, the power of a single stirring wheel is weak, and the washing effect of the water flow on the laundry is weakened.

[0060] In this embodiment, when washing clothes, the stirring wheel 10 rotates to drive the water flow to rotate, forming a main driving water flow, and washing clothes through the impact of the water flow and the friction of the clothes themselves. At the same time, the stirring rod 11 rotates under the drive of the stirring wheel 10, stirring the water flow in the top space of the stirring wheel 10. In this way, the stirring wheel 10 and the stirring rod 11 jointly form a dual-power drive for the water flow, increasing the stirring of the clothes, thereby improving the washing efficiency and the cleaning effect; at the same time, when the clothes are clothes, the stirring rod 11 can also play a certain anti-entanglement effect.

[0061] It is understandable that the shapes of the stirring wheel 10 and the stirring rod 11 and the installation top wall 101 are not limited. For example, in some examples, the stirring wheel 10 is roughly circular and coaxially arranged with the washing drum, the stirring rod 11 is roughly cylindrical, and the installation top wall 101 can be located at the center of the stirring wheel 10. In this way, when the stirring wheel 10 and the stirring rod 11 are docked, the stirring rod 11 docks with the center of the stirring wheel 10, and the stirring rod 11 can be roughly located in the center area of ​​the washing drum. For example, in some examples, the stirring wheel 10, the stirring rod 11, and the washing drum are coaxially arranged.

[0062] See also Figures 1 to 10 The stirring rod 11 has a hollow chamber 11a, a side wall of the stirring rod 11 is provided with a through hole 11b, a bottom end of the stirring rod 11 has a bottom wall 111, the bottom wall 111 is provided with a second connecting portion 1111 and a second flow channel hole 111a, and the filter unit 12 is arranged in the hollow chamber 11a.

[0063] It is understood that the bottom wall 111 is located at the bottom of the hollow chamber 11a and is used to be installed with the stirring wheel 10. That is, the bottom side of the hollow chamber 11a is not completely open. The second flow channel hole 111a is connected to the first flow channel hole 101a, and is used to guide the water entering the hollow chamber 11a through the first flow channel hole 101a to the bottom side area of ​​the stirring wheel 10.

[0064] The stirring wheel 10 and the stirring rod 11 are connected via a first connecting portion 1011 and a second connecting portion 1111 .

[0065] In this embodiment, the stirring wheel 10 and the stirring rod 11 are split structures, that is, the stirring wheel 10 and the stirring rod 11 can be manufactured separately and then connected by the first connecting portion 1011 and the second connecting portion 1111. The mold complexity of the split stirring rod 11 and stirring wheel 10 is low, which can reduce the manufacturing difficulty and thus reduce the production cost. In the related art, the stirring rod and the stirring wheel are formed into an integrated structure, the mold complexity is high, it is not easy to demold, and the production cost is high.

[0066] During the rotation of the stirring device 1, negative pressure is formed in the bottom area of ​​the stirring wheel 10. The water in the hollow chamber 11a is filtered by the filter unit 12, and then enters the first flow channel hole 101a through the second flow channel hole 111a, and then enters the bottom area of ​​the stirring wheel 10. The water around the stirring rod 11 is replenished into the hollow chamber 11a in the stirring rod 11 through the through hole 11b. In this way, the cycle is continuously carried out, and impurities in the water can also be circulated and filtered, thereby improving the filtering effect and increasing the cleaning effect on the laundry.

[0067] The specific structure of the filter unit 12 is not limited. For example, the filter unit 12 can be a filter screen, which has a simple structure and is easy to install.

[0068] The stirring device 1 provided in the embodiment of the present application performs dual-power drive on the water flow through the cooperation of the stirring rod 11 and the stirring wheel 10, thereby increasing the stirring of the laundry, thereby improving the washing effect of the laundry; the water flow can quickly enter the hollow chamber 11a under the action of the stirring rod 11, and the second flow channel hole 111a and the first flow channel hole 101a provided at the cooperation between the stirring wheel 10 and the stirring rod 11 facilitate the water flow to pass through the hollow chamber 11a and the filter unit 12 into the bottom side area of ​​the stirring wheel 10, and then return to the washing drum of the washing device, thereby realizing the circulation filtration of the water flow, and further The cleaning effect on the laundry is further increased; in addition, the stirring wheel 10 and the stirring rod 11 are manufactured separately, which can reduce the manufacturing difficulty, thereby reducing the manufacturing difficulty of the stirring device 1; by designing the first connecting portion 1011 and the second connecting portion 1111, the stirring rod 11 and the stirring wheel 10 are connected, which can also increase the connection strength between the stirring wheel 10 and the stirring rod 11, reduce the probability of the stirring rod 11 and the stirring wheel 10 breaking at the fitting point, increase the rotation stability of the stirring device 1, and make the stirring device 1 have sufficient structural strength when realizing an efficient filtering cycle.

[0069] The specific structure and connection method of the first connection part 1011 and the second connection part 1111 are not limited. For example, the connection method of the first connection part 1011 and the second connection part 1111 can be a clamping connection, a screw connection, etc.

[0070] The first connection portion 1011 and the second connection portion 1111 may be directly connected. For example, the first connection portion 1011 and the second connection portion 1111 may be connected by snapping.

[0071] The first connection portion 1011 and the second connection portion 1111 may also be connected via other structures.

[0072] For example, in some embodiments, see Figure 4 The stirring device 1 includes a first connecting member 13 , and the first connecting member 13 connects the first connecting portion 1011 and the second connecting portion 1111 .

[0073] Specifically, the connection between the stirring wheel 10 and the stirring rod 11 can be achieved by connecting the first connecting part 1011 and the second connecting part 1111 through the first connecting member 13. The first connecting member 13 can tightly connect the first connecting part 1011 and the second connecting part 1111 to increase the connection tightness of the stirring device 1.

[0074] It is understandable that the structure of the first connecting member 13 is not limited, and can be a screw, a rivet, etc. For example, the first connecting member 13 can be a screw, which fastens the first connecting portion 1011 and the second connecting portion 1111, and the screw connection has strong fastness.

[0075] For example, in some embodiments, one of the first connection portion 1011 and the second connection portion 1111 is a protruding structure, and the other is a concave structure, and the protruding structure is inserted into the concave structure.

[0076] In this embodiment, the protruding structure and the recessed structure can enhance the structural strength of the bottom wall 111 and the mounting top wall 101. Therefore, even when the second flow channel hole 111a is set on the bottom wall 111 and the first flow channel hole 101a is set on the mounting top wall 101, the structural strength of the bottom wall 111 and the mounting top wall 101 can still be guaranteed, which is beneficial to improving the connection reliability between the two at the mating point.

[0077] In this embodiment, due to the cooperation between the recessed structure and the protruding structure, the agitator rod 11 and the agitator wheel 10 can be docked without the need for an additional alignment structure, thereby improving the assembly simplicity of the agitator 1. During the rotation of the agitator 1, the protruding structure and the recessed structure can also play a role in transmitting torque, bearing shear force, and increasing the structural stability of the agitator 1. In the embodiment in which the first connecting member 13 is provided, the cooperation between the recessed structure and the protruding structure can improve the stress state of the first connecting member 13, so that the first connecting member 13 is less or almost completely free of shear force. In this way, the possibility of the first connecting member 13 breaking can be reduced, and the service life and reliability of the first connecting member 13 can be improved, thereby further improving the structural reliability and rotation stability of the agitator 1.

[0078] It should be noted that, in some examples, after the first connection part 1011 and the second connection part 1111 are butted against the recessed structure through the protruding structure, the first connection part 1011 and the second connection part 1111 can be tightly connected through the first connection member 13. In this way, it is convenient to align the first connection part 1011 and the second connection part 1111, thereby facilitating the connection of the first connection member 13, and can further increase the tightness of the connection between the stirring wheel 10 and the stirring rod 11. Of course, in other examples, the first connection part 1011 and the second connection part 1111 are directly butted against the recessed structure through the protruding structure, and there is no need to set up an additional connection structure to connect the first connection part 1011 and the second connection part 1111; in still other examples, the first connection part 1011 and the second connection part 1111 are directly connected through the first connection member 13, and there is no need to first butt the first connection part 1011 and the second connection part 1111 through the protruding structure and the recessed structure.

[0079] It should be noted that one of the first connection portion 1011 and the second connection portion 1111 is a protruding structure, and the other is a recessed structure, which may include two situations.

[0080] In the first type, the first connecting portion 1011 is a protruding structure, and the second connecting portion 1111 is a recessed structure, that is, the protruding structure is arranged on the stirring wheel 10, and the recessed structure is arranged on the stirring rod 11. It can be understood that, in this embodiment, the protruding structure is a structure in which the top wall 101 is installed to protrude toward the side close to the stirring rod 11, and the recessed structure is a structure in which the bottom wall 111 is recessed toward the direction away from the stirring wheel 10.

[0081] The second type is that the first connecting part 1011 is a recessed structure, and the second connecting part 1111 is a protruding structure, that is, the recessed structure is arranged on the stirring wheel 10, and the protruding structure is arranged on the stirring rod 11. It can be understood that, in this embodiment, the recessed structure is a structure in which the top wall 101 is recessed in the direction away from the stirring rod 11, and the protruding structure is a structure in which the bottom wall 111 is protruding toward the stirring wheel 10.

[0082] For some examples, see Figures 4 to 8 The mounting top wall 101 is provided with a boss 1012 , and a connecting hole 1012 a is provided in the middle area of ​​the boss 1012 . The connecting hole 1012 a is used to pass the second connecting member 14 , and the second connecting member 14 is used to connect the stirring shaft of the stirring wheel 10 .

[0083] For example, during the assembly process, the second connecting member 14 is passed through the connecting hole 1012a of the stirring wheel 10 from top to bottom and screwed into the top end of the stirring shaft, so that the stirring wheel 10 and the stirring shaft can be connected.

[0084] In this embodiment, the stirring wheel 10 and the stirring shaft are connected by the second connecting member 14. In this way, during the washing process of the washing device, the stirring shaft drives the stirring wheel 10 to rotate, and the stirring wheel 10 drives the stirring rod 11 to rotate. In other words, the stirring shaft is not directly connected to the stirring rod 11, and the two are connected by the stirring wheel 10. In this way, when the stirring rod 11 needs to be disassembled and cleaned, it is only necessary to disassemble the stirring rod 11 from the stirring wheel 10. In addition, the second connecting member 14 does not need to bear the shear force caused by the torque between the stirring wheel 10 and the stirring rod 11, and the connection reliability between the stirring wheel 10 and the stirring shaft is high.

[0085] The specific structure of the second connecting member 14 is not limited. For example, the second connecting member 14 can be a screw. After the first connecting part 1011 and the second connecting part 1111 are connected, the screw passes through the hollow chamber 11a and the bottom wall 111, and is inserted into the second connecting hole 1012a. The screw is tightened to achieve the connection and fixation of the stirring wheel 10 and the stirring rod 11.

[0086] For some examples, see Figures 6 to 10 The bottom wall 111 is provided with a receiving groove 111b, and the boss 1012 is inserted into the receiving groove 111b.

[0087] In this way, after the first connecting part 1011 and the second connecting part 1111 are connected, the boss 1012 is inserted into the receiving groove 111b, which can further realize the alignment of the stirring rod 11 and the stirring wheel 10. In addition, the insertion of the boss 1012 into the receiving groove 111b also facilitates the penetration of the second connecting member 14 and the connecting hole 1012a, making the assembly of the stirring device 1 simpler and more convenient.

[0088] The number of the first connection part 1011 and the second connection part 1111 is not limited, and can be one or more. The first connection part 1011 and the second connection part 1111 and the first connection member 13 are arranged in a one-to-one correspondence.

[0089] For some examples, see Figure 7 and Figure 8 , the number of the first connection parts 1011 is multiple, and the number of the second connection parts 1111 is multiple.

[0090] The arrangement of multiple first connection parts 1011 and multiple second connection parts 1111 can jointly bear the shear force caused by the torque between the stirring wheel 10 and the stirring rod 11. The shear force borne by a single first connection part 1011 and a single second connection part 1111 is smaller, which is convenient for increasing the rotation stability of the stirring device 1. In the embodiment in which the first connection part 1011 and the second connection part 1111 are connected by the first connecting member 13, the multiple first connection parts 1011 and the multiple second connection parts 1111 can also make the stress state of the single first connecting member 13 better, further improving the service life and working reliability of the first connecting member 13.

[0091] The plurality of first connection parts 1011 and the plurality of second connection parts 1111 are respectively arranged around the circumference of the boss 1012. In this way, the torque transmitted by each first connection part 1011 and the second connection part 1111 can be more uniform, the shear force borne can also be more uniform, and the structure of the connection between the stirring rod 11 and the stirring wheel 10 can also be made more compact. It can be understood that the plurality of second connection parts 1111 are arranged around the circumference of the boss 1012, which means that the second connection parts 1111 are arranged around the circumference of the boss 1012 after the second connection parts 1111 are connected with the first connection parts 1011.

[0092] It can be understood that the boss 1012 is roughly located at the center of the area enclosed by the first connecting part 1011 and the second connecting part 1111, that is, the connecting hole 1012a is roughly located at the center of the area enclosed by the first connecting part 1011 and the second connecting part 1111. This makes it easy to position the connecting hole 1012a and align the second connecting member 14 with the connecting hole 1012, making the connection between the stirring shaft and the stirring wheel 10 simpler and more convenient.

[0093] The number and location of the first flow channel holes 101 a and the second flow channel holes 111 a are not limited.

[0094] For some examples, see Figures 7 to 10 , the number of the first flow channel holes 101a is multiple, and the number of the second flow channel holes 111a is multiple. In this way, the water filtered by the filter unit 12 has multiple paths, so that a sufficient amount of water can flow through the second flow channel holes 111a and the first flow channel holes 101a to the bottom area of ​​the stirring wheel 10 each time, so as to ensure water circulation, thereby improving the cleaning effect.

[0095] It can be understood that the number of the first flow channel holes 101a and the number of the second flow channel holes 111a are the same, that is, the first flow channel holes 101a and the second flow channel holes 111a are arranged in a one-to-one correspondence.

[0096] The plurality of first connection portions 1011 and the plurality of first flow passage holes 101 a are alternately arranged around the circumference of the boss 1012 , and the plurality of second connection portions 1111 and the plurality of second flow passage holes 111 a are alternately arranged around the circumference of the boss 1012 .

[0097] It can be understood that multiple first connection parts 1011 and multiple first flow channel holes 101a are alternately arranged around the circumference of the boss 1012, which means that along the circumference of the boss 1012, the first flow channel holes 101a are arranged on both adjacent sides of any first connection part 1011, and the first connection parts 1011 are arranged on both adjacent sides of any first flow channel hole 101a.

[0098] Exemplarily, the plurality of first connection portions 1011 and the plurality of first flow channel holes 101 a are alternately arranged along the circumferential direction on the same circle, the center of the circle is located on the rotation axis of the stirring wheel 10 , and the contour range of the circle does not exceed the mounting top wall 101 .

[0099] Multiple second connection parts 1111 and multiple second flow channel holes 111a are alternately arranged around the circumference of the boss 1012, which means that along the circumference of the boss 1012, second flow channel holes 111a are arranged on both adjacent sides of any second connection part 1111, and second connection parts 1111 are arranged on both adjacent sides of any second flow channel hole 111a.

[0100] It should be noted that the multiple second connection parts 1111 and the multiple second flow channel holes 111a are arranged circumferentially around the boss 1012. After the stirring wheel 10 is docked with the stirring rod 11, that is, after the second connection part 1111 is docked with the first connection part 1011, the second connection parts 1111 and the second flow channel holes 111a are alternately arranged circumferentially around the boss 1012.

[0101] Exemplarily, the plurality of second connection portions 1111 and the plurality of second flow channel holes 111 a are alternately arranged along the circumferential direction on the same circle, the center of the circle is located on the rotation axis of the stirring wheel 10 , and the contour range of the circle does not exceed the bottom wall 111 .

[0102] In this embodiment, the arrangement of the first connecting portion 1011 and the first flow channel hole 101a, and the arrangement of the second connecting portion 1111 and the second flow channel hole 111a can make the structural arrangement of the connection between the stirring rod 11 and the stirring wheel 10 more uniform and compact, the torque transmitted by the first connecting portion 1011 and the second connecting portion 1111 and the shear force borne are more uniform, and the water flow flowing through the second flow channel hole 111a and the first flow channel hole 101a can also be more uniform; the provision of multiple second flow channel holes 111a and the first flow channel hole 101a can speed up the water flow rate, thereby improving the water circulation rate and increasing the cleaning effect on the laundry.

[0103] For some examples, see Figures 4 to 8 , the first connection portion 1011 is a recessed structure.

[0104] Specifically, the first connecting portion 1011 is a recessed structure that is recessed in the direction away from the stirring rod 11. At this time, the second connecting portion 1111 is a protruding structure that is protruding in the direction close to the stirring wheel 10. In this way, when the stirring rod 11 and the stirring wheel 10 are docked along the top and bottom directions, the second connecting portion 1111 is a protruding structure that is easier to observe, making the docking of the first connecting portion 1011 and the second connecting portion 1111 faster and more accurate.

[0105] Exemplarily, in some embodiments, after the first connection part 1011 and the second connection part 1111 are aligned, when the first connection part 1011 and the second connection part 1111 are connected by the first connection member 13, the first connection member 13 can be first passed through the first connection part 1011 and then inserted into the second connection part 1111 to connect the first connection part 1011 and the second connection part 1111.

[0106] The portion between two adjacent first connection portions 1011 is higher than the first connection portion 1011 , thereby forming a convex structure 1013 . The first flow channel hole 101 a penetrates the convex structure 1013 . On the other hand, the convex structure 1013 can separate two adjacent first connecting parts 1011 and play a positioning role. When the stirring rod 11 is docked with the stirring wheel 10, the second connecting part 1111 can be directly inserted into the first connecting part 1011 without docking with the convex structure 1013, thereby increasing the docking accuracy. In addition, the convex structure 1013 can also increase the structural strength of the docking point between the stirring rod 11 and the stirring wheel 10, further increasing the assembly reliability of the stirring device 1. In addition, the first flow channel hole 101a passes through the convex structure 1013, and the filtered washing water flows directly toward the first flow channel hole 101a through the second flow channel hole 111a to the bottom area of ​​the stirring wheel 10, without affecting the first connection part 1011 and the second connection part 1111. In addition, the first flow channel hole 101a is set on the convex structure 1013, and the structure of installing the top wall 101 can be simpler and more compact.

[0107] For some examples, see Figure 8 , the top surface of the convex hull structure 1013 is located higher than the top surface of the boss 1012 .

[0108] In this way, when the stirring rod 11 is docked with the stirring wheel 10 along the top-bottom direction, it is first docked with the convex structure 1013, the second connecting part 1111 is inserted into the first connecting part 1011, and then docked with the boss 1012. In this way, the stirring rod 11 is first aligned with the first connecting part 1011, and then docked with the boss 1012. The top surface of the boss 1012 is lower than the top surface of the convex structure 1013. On the one hand, it will not interfere with the cooperation between the first connecting part 1011 and the second connecting part 1111. After the first connecting part 1011 is aligned with the second connecting part 1111, the boss 1012 can also be directly aligned with the stirring rod 11, and the installation of the stirring device 1 is more convenient.

[0109] For some examples, see Figure 8 and Fig. 9 The stirring wheel 10 has a mounting side wall 103 , which extends around the periphery of the mounting top wall 101 . The convex structure 1013 is connected to the mounting side wall 103 at the radial outer end of the stirring wheel 10 , and is spaced apart from the boss 1012 at the inner end.

[0110] That is to say, the boss 1012 is arranged roughly near the center of the mounting top wall 101, the convex structure 1013 is arranged on the outside of the boss 1012, and the outer end of the convex structure 1013 is connected to the mounting side wall 103. The mounting side wall 103 can provide force support for the convex structure 1013, further improving the structural strength of the joint between the stirring wheel 10 and the stirring rod 11. The inner end of the convex structure 1013 is spaced apart from the boss 1012, and surplus space can be left, so that when the first connecting part 1011 and the second connecting part 1111 are docked, there is no interference with the boss 1012, thereby increasing the docking reliability of the stirring wheel 10 and the stirring rod 11.

[0111] In some embodiments, the total area S1 of the through holes 11 b is greater than the total area S2 of the second flow channel holes 111 a , and greater than the total area S3 of the first flow channel holes 101 a , that is, S1>S2, S1>S3.

[0112] That is to say, per unit time, the flow rate of washing water flowing into the hollow chamber 11a through the through hole 11b is greater than the flow rate of washing water flowing to the bottom area of ​​the stirring wheel 10 through the second flow channel hole 111a and the first flow channel hole 101a. A part of the washing water entering the stirring rod 11 through the through hole 11b is filtered by the filter unit 12, and the other part is stored in the hollow chamber 11a waiting for filtration. In this way, the filter unit 12 can filter the washing water uninterruptedly. The filter unit 12 can filter enough washing water each time, thereby capturing enough impurities and increasing the cleaning effect.

[0113] In some embodiments, the total area S1 of each through hole 11b and the total area S2 of each second flow channel hole 111a are

[0114] 7.5.

[0116] It is understandable that if the ratio of the total area of ​​each through hole to the total area of ​​each second flow channel hole is too large, the filter unit will not be able to filter the washing water stored in the hollow chamber in time, and the water in the hollow chamber will flow back through the through holes, affecting the circulation and filtration of the water flow; if the ratio of the total area of ​​each through hole to the total area of ​​each second flow channel hole is too small, the amount of washing water in the hollow chamber is small, affecting the uninterrupted filtration of the washing water by the filter unit.

[0117] In this embodiment, the ratio of the total area of ​​each through hole 11b to the total area of ​​each second flow channel hole 111a is relatively appropriate. While achieving stable circulation filtration of the washing water, the filter unit 12 can also continuously filter sufficient impurities, thereby increasing the filtration reliability of the stirring device 1.

[0118] In some embodiments, the hollow chamber 11 a and the filter unit 12 are both located higher than the top edge of the mounting top wall 101 .

[0119] That is, the mounting top wall 101 is located at the bottom side of the hollow chamber 11a and the filter unit 12, so that water flows through the hollow chamber 11a and the filter unit 12 toward the mounting top wall 101 at the bottom side, thereby increasing the reliability of water flow.

[0120] The specific structure of the stirring rod 11 is not limited.

[0121] For some examples, see Fig. 9 and Fig.10 The stirring rod 11 includes a rod body 112 , a bracket 113 and an end cover 114 . The end cover 114 is detachably arranged at the top end of the rod body 112 . The top end of the bracket 113 is connected to the end cover 114 . The filter unit 12 is arranged on the bracket 113 .

[0122] Specifically, the inner wall of the rod body 112 encloses a hollow chamber 11a, and the through hole 11b passes through the side wall of the rod body 112. During the washing process, the rod body 112 stirs the water flow driven by the stirring wheel 10, and the bracket 113 supports the filter unit 12, so that the filter unit 12 can remain stable and not fall out when filtering the washing water.

[0123] The end cap 114 is arranged at the top end of the rod body 112, that is, the end cap 114 is arranged at the end of the rod body 112 away from the stirring wheel 10. The end cap 114 can close the end of the hollow chamber 11a away from the stirring wheel 10, thereby reducing the probability of water splashing out from the end of the hollow chamber 11a away from the stirring wheel 10. The end cap 114 is detachably connected to the top end of the rod body 112, which can facilitate the first connecting member 13 to connect the stirring wheel 10 and the stirring rod 11; in addition, it can also increase the appearance of the stirring device 1.

[0124] There is no limitation on the detachable connection method between the end cap 114 and the top end of the rod body 112 , which may be a threaded connection or a snap-on connection, which is not limited here.

[0125] In some embodiments, at least a portion of the end cover 114 is provided with a light-transmitting window.

[0126] That is to say, during the operation of the stirring device 1, the hollow chamber 11a and the filter unit 12 can be exposed to the user's field of view through this light-transmitting window, so that the user can see the impurity collection situation of the filter unit 12, thereby facilitating the timely cleaning and replacement of the filter unit 12 and increasing the filtering reliability of the stirring device 1.

[0127] For some examples, see Fig. 9 and Fig.10The stirring rod 11 further includes blades 115, which are spirally wrapped around the circumferential outer side of the rod body 112. During the washing process, the laundry can be turned over and moved up and down along the spiral blades 115, thereby increasing the washing uniformity and improving the overall cleaning effect.

[0128] The shape of the filter unit 12 is not limited.

[0129] For some examples, see Figure 2 The filter unit 12 is cylindrical, so that the contact area with the washing water can be increased, the filtering effect can be increased, and thus the cleaning effect on the laundry can be improved.

[0130] The top end of the filter unit 12 is open to receive water flowing into the hollow chamber 11 a through the through hole 11 b .

[0131] The outer diameter of the top of the filter unit 12 is greater than the outer diameter of the bottom, and the edge of the top contacts the inner wall of the rod body 112. On the one hand, the filtering area can be increased, the top of the filter unit 12 filters the water flow, and the impurities such as hair scraps filtered out can be accumulated at the bottom of the filter unit 12 under the action of gravity and the flushing of the water flow, reducing the probability of clogging of the filter unit 12 and increasing the filtering effect; on the other hand, it is also convenient to clean the filter unit 12.

[0132] The edge of the top end of the filter unit 12 contacts the inner wall of the rod body 112, that is, the edge of the top end of the filter unit 12 abuts against the inner wall of the rod body 112, and there is no gap between the two. In this way, the washing water entering the hollow chamber 11a through the through hole 11b must first be filtered by the filter unit 12 before it can flow toward the second flow channel hole 111a at the bottom, thereby reducing the probability of the washing water entering the hollow chamber 11a flowing out through the gap between the filter unit 12 and the rod body 112, thereby increasing the filtering reliability.

[0133] For example, in some embodiments, the filter unit 12 is substantially conical in shape, and can produce a funnel-like effect when filtering the washing water, so as to increase the reliability of the circulating filtration of the washing water.

[0134] It is understandable that the filter unit 12 may be evenly distributed with fine filter holes around its circumference to filter the washing water.

[0135] The following combination Figures 1 to 10 , briefly describe the assembly process of the stirring device 1.

[0136] During assembly, the first connecting part 1011 and the second connecting part 1111 are plugged into each other. At this time, the second flow channel hole 11a is connected to the first flow channel hole 101a, the boss 1012 is inserted into the accommodating groove 111b, and then the second connecting member 14 is inserted into the connecting hole 1012a through the hollow chamber 11a. The first connecting member 13 connects the first connecting part 1011 and the second connecting part 1111, and then the bracket 113 equipped with the filter unit 12 is inserted into the rod body 112. Since the bracket 113 is connected to the end cover 114, when the bracket 113 moves to the target position, the end cover 114 is covered on the top of the rod body 112 to realize the installation of the stirring device 1. When the filter unit 12 needs to be cleaned or replaced, the end cap 114 is separated from the rod body 112, and the end cap 114 is lifted upward. The end cap 114 carrying the bracket 113 and the filter unit 12 are pulled out from the rod body 112, so that the filter unit 12 can be cleaned, replaced, etc.
