[0038] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0039] Reference will be made below to Figures 1-8 describe the spray assembly 100 according to the embodiment of the first aspect of the present utility model.

[0040] As Figures 1-7 shown, the spray assembly 100 according to the embodiment of the first aspect of the present utility model includes: a filter member 10, a first spray arm 20, and a regional spray arm 30.

[0041] A diversion cavity 101 is defined inside the filter member 10. The filter member 10 has a first water inlet 121, a first water outlet, and a regional water outlet 122 that communicate with the diversion cavity 101; the first spray arm 20 communicates with the first water outlet; the regional spray arm 30 communicates with the regional water outlet 122. Specifically, the first water inlet 121 is provided below the first water outlet and the regional water outlet 122. The first water inlet 121 communicates with the first water outlet and the first water inlet 121 communicates with the regional water outlet 122. Water flow can flow in from the first water inlet 121 and flow out from the first water outlet and the regional water outlet 122.

[0042] For example Figure 3 and Figure 5 shown, the first spray arm 20 can be arranged in a long strip shape. The first spray arm 20 is provided with first spray holes 21. The first spray arm 20 communicates with the first water outlet. Further, the number of the first spray holes 21 can be multiple. For example, the number of the first spray holes 21 can be two, three, four, five, six or more. The multiple first spray holes 21 are respectively arranged on both sides of the first spray arm 20. Water flow can flow from the first water outlet to the first spray arm 20 and be ejected upward from the first spray holes 21 to perform the cleaning work. Further, the first spray arm 20 can perform rotary spraying.

[0043] For example Figure 6 and Figure 7As shown, area spray arms 30 are provided with area spray holes 31. The area spray arms 30 are communicated with area water outlets 122. Further, the number of area spray holes 31 can be multiple. For example, the number of area spray holes 31 can be two, three, four, five, six or more. The multiple area spray holes 31 are evenly arranged on the outer peripheral side of the area spray arms 30. An area water outlet pipeline 32 is further arranged between the area spray arms 30 and the filter element 10. One end of the area water outlet pipeline 32 is connected to the area water outlet 122, and the other end of the area water outlet pipeline 32 is connected to the area spray arms 30. Water flow can flow from the area water outlet 122 to the area water outlet pipeline 32 and the area spray arms 30 in sequence, and be ejected upward from the area spray holes 31 to perform cleaning work. Further, the area spray arms 30 can perform rotary spraying. In a specific example, the number of area spray holes 31 is three.

[0044] In this embodiment, when the spraying assembly 100 works, water flow can flow into the first water inlet 121 of the filter element 10. The filter element 10 can effectively filter impurities in the water entering the first water inlet 121, so as to effectively avoid the influence of impurities in the water on the cleaning effect. In addition, the filter element 10 can also prevent sundries generated during cleaning from flowing downward into the water. After the water flow flows into the first water inlet 121, a part of the water can flow out from the first water outlet, and another part of the water can flow out from the area water outlet 122. Thus, the first water inlet 121 of the filter element 10 can integrate the water flow of the first water outlet and the water flow of the area water outlet 122 in a water supply pipeline, thereby avoiding setting a separately controlled area spray arm 30.

[0045] In addition, compared with the spraying assembly 100 in the prior art that is provided with a separately controlled area spray arm 30, the present application directly forms a connection between the first water outlet connecting the first spray arm 20 and the area water outlet 122 connecting the area spray arm 30 on the filter element 10, so as to effectively reduce the additionally provided pipeline components, thereby effectively simplifying the structural configuration and effectively reducing the cost. In addition, the filter element 10 is arranged under the first spray arm 20 and the area spray arms 30, so as to effectively save space and thus effectively expand the cleaning area.

[0046] The water flowing out from the first water outlet can flow to the first spray arm 20 and is finally ejected rotatably from the first spray holes 21 on the first spray arm 20, so as to effectively perform cleaning work. The water flowing out from the area water outlet 122 can flow to the area spray arms 30 and is finally ejected rotatably from the area spray holes 31 on the area spray arms 30, so as to effectively expand the cleaning area and thoroughly clean the difficult-to-clean corner positions. The first spray arm 20 and the area spray walls cooperate with each other to effectively strengthen the cleaning effect, effectively improve the washing performance, and thus effectively improve the cleaning efficiency.

[0047] According to the spray assembly 100 of the embodiments of the present utility model, by providing a filter element 10, a first spray arm 20, and a regional spray arm 30 in the spray assembly 100, a diversion chamber 101 is defined within the filter element 10. The filter element 10 has a first water inlet 121, a first water outlet, and a regional water outlet 122 that communicate with the diversion chamber 101. The first spray arm 20 is in communication with the first water outlet, and the regional spray arm 30 is in communication with the regional water outlet 122. The regional spray arm 30 can effectively expand the cleaning area and effectively enhance the cleaning effect, thereby effectively improving the cleaning efficiency and further effectively enhancing the user experience. In addition, the filter element 10 can effectively reduce the additional pipeline components provided, thereby effectively simplifying the structural configuration and effectively reducing costs.

[0048] In an embodiment of the present utility model, as Figures 3-5 shown, the filter element 10 includes a filter main body 11 and a support 12 that are separately provided. The support 12 is connected to the filter main body 11 and is arranged below the filter main body 11. The filter main body 11 and the support 12 jointly define the diversion chamber 101.

[0049] For example, the support 12 can be sleeved on the lower side of the filter main body 11. That is to say, the support 12 and the filter main body 11 are detachably connected, which can facilitate the demolding of the filter element 10. At the same time, it can also facilitate the disassembly, assembly, and maintenance of the filter element 10. The support 12 is connected to the filter main body 11 and jointly forms a closed diversion chamber 101 with the filter main body 11, which can effectively ensure the reasonable distribution of water flow within the diversion chamber 101.

[0050] In this embodiment, by separately providing the filter main body 11 and the support 12 in the filter element 10, the support 12 is connected to the filter main body 11 and is arranged below the filter main body 11, and the filter main body 11 and the support 12 jointly define the diversion chamber 101, which can not only improve the convenience of demolding the filter element 10, but also effectively achieve the diversion of water flow, thereby effectively realizing the control of water flow.

[0051] In an embodiment of the present utility model, as Figure 4 shown, the first water inlet 121 is formed in the support 12 and penetrates the support 12 in the vertical direction. The regional water outlet 122 is formed in the support 12, and the first water outlet is formed in the filter main body 11.

[0052] When the water flow enters the support 12 from the first water inlet 121, it can flow upward into the diversion chamber 101. After that, a part of the water flow flows through the regional water outlet 122 and then flows to the regional spray arm 30, and another part of the water flow flows through the first water outlet and flows to the first spray arm 20. Thus, the flow path of the water flow can be effectively optimized, and the flow efficiency of the water flow can be improved.

[0053] In this embodiment, the first water inlet 121 is formed on the support 12 and penetrates the support 12 in the vertical direction, the area water outlet 122 is formed on the support 12, and the first water outlet is formed on the filter body 11, which can effectively improve the efficiency of water flow diversion and flow, so as to ensure that the water flow entering the first spray arm 20 and the area spray arm 30 has sufficient pressure, and further effectively ensure the water spraying effect.

[0054] In an embodiment of the present utility model, as Figures 3-5 shown, the first spray arm 20 has a first connecting pipe portion 22. A support platform 131 is provided in the diversion cavity 101. The lower end of the first connecting pipe portion 22 extends into the diversion cavity 101 and is supported on the support platform 131. For example, the first connecting pipe portion 22 extends in the vertical direction. Further, the cross-sectional shape of the first connecting pipe portion 22 can be an annular shape. A support platform 131 is provided in the diversion cavity 101, and the shape of the support platform 131 can be two-thirds of an annular shape.

[0055] The lower end of the first connecting pipe portion 22 extends into the diversion cavity 101 and abuts against the upper surface of the support platform 131, so that the first connecting pipe portion 22 can be effectively supported on the spray wall seat, thereby effectively fixing the first spray arm 20, and further effectively ensuring that the first spray arm 20 can maintain stability when rotating and spraying water. When the spraying assembly 100 works, the water flow can flow from the first water outlet to the inside of the first connecting pipe portion 22, and flow upward in the first connecting pipe portion 22, and finally be ejected from the first spray hole 21.

[0056] In this embodiment, by providing the first connecting pipe portion 22 in the first spray arm 20, and providing the support platform 131 in the diversion cavity 101, the lower end of the first connecting pipe portion 22 extends into the diversion cavity 101 and is supported on the support platform 131, the vibration and displacement of the first spray arm 20 during operation can be effectively reduced, thereby effectively improving the stability of the first spray arm 20. In addition, it is also convenient for the installation and disassembly of the first spray arm 20, and improves the convenience of maintenance.

[0057] In an embodiment of the present utility model, as Figures 3-5 shown, the first connecting pipe portion 22 is located directly above the first water inlet 121, and the first connecting pipe portion 22 is spaced apart from the bottom wall of the diversion cavity 101. For example, the first connecting pipe portion 22 is located directly above the first water inlet 121, so that the water flow can first contact the first connecting pipe portion 22 when entering the diversion cavity 101 from the first water inlet 121, so that the water flow can quickly enter the first connecting pipe portion 22, and further effectively reduce the residence time and path length of the water flow in the diversion cavity 101.

[0058] For example, the first connecting pipe portion 22 is arranged at an interval from the bottom wall of the flow dividing cavity 101, that is to say, there is a certain interval between the first connecting pipe portion 22 and the bottom wall of the flow dividing cavity 101 in the up and down directions, so that it can effectively ensure that when water flows into the flow dividing cavity 101 from the first water inlet 121, part of the water flow can enter the first spray arm 20, and the other part of the water flow can enter the area spray wall. In addition, it can effectively maintain the water pressure balance in the flow dividing cavity 101 and avoid the problem of uneven water flow distribution caused by too high local pressure.

[0059] In this embodiment, by arranging the first connecting pipe portion 22 directly above the water inlet, the resistance and time for water to enter the first spray arm 20 can be effectively reduced, thereby effectively improving the spraying speed of the first spray arm 20, and further effectively ensuring the cleaning effect; by arranging the first connecting pipe portion 22 at an interval from the bottom wall of the flow dividing cavity 101, the water flow can be effectively divided and the water pressure balance in the flow dividing cavity 101 can be effectively maintained, thereby effectively ensuring the flow dividing effect.

[0060] In an embodiment of the present utility model, as Figure 4 shown, in the up and down directions, the distance between the lower edge of the first connecting pipe portion 22 and the bottom wall of the flow dividing cavity 101 is greater than or equal to 2 mm. For example, the distance H between the lower edge of the first connecting pipe portion 22 and the bottom wall of the flow dividing cavity 101 can be 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, and 3 mm.

[0061] In this embodiment, by setting the distance between the lower edge of the first connecting pipe portion 22 and the bottom wall of the flow dividing cavity 101 to be greater than or equal to 2 mm, it can effectively prevent impurities with larger particles from blocking the area between the first connecting pipe portion 22 and the bottom wall, ensure the smoothness of the water flow channel, thereby further ensuring the flow dividing effect, and ensuring that the spraying assembly 100 can operate stably for a long time.

[0062] In an embodiment of the present utility model, as Figure 4 shown, the filter element 10 has a fitting pipe portion 13 extending in the up and down directions, at least part of the fitting pipe portion 13 extends into the flow dividing cavity 101, the first connecting pipe portion 22 is fitted in the fitting pipe portion 13, and a support platform 131 is formed on the inner wall of the fitting pipe portion 13.

[0063] For example, part of the fitting pipe portion 13 extends into the flow dividing cavity 101; or, the fitting pipe portion 13 extends entirely into the flow dividing cavity 101. In a specific example, for example Figure 4As shown, the lower end portion of the fitting pipe portion 13 extends into the flow splitting chamber 101. A support platform 131 is formed on the inner wall of the fitting pipe portion 13 and is located at the lower end of the fitting pipe portion 13. Further, the outer peripheral edge of the support platform 131 is fixedly connected to the inner wall of the fitting pipe portion 13. In a specific example, a boss 132 protruding along the outer peripheral edge of the fitting pipe portion 13 is provided at the upper end of the fitting pipe portion 13, and the first spray arm 20 can be snap-connected to the filter element 10 through the boss 132.

[0064] In this embodiment, by providing the fitting pipe portion 13 extending vertically on the filter element 10, and at least a part of the fitting pipe portion 13 extending into the flow splitting chamber 101, the first connecting pipe portion 22 is fitted into the fitting pipe portion 13, and the support platform 131 is formed on the inner wall of the fitting pipe portion 13, it is possible to accurately position the first connecting pipe portion 22 when installing the first spray arm 20, effectively improve the positioning speed, and in addition, can effectively support and fix the first connecting pipe portion 22.

[0065] In an embodiment of the present utility model, as Figure 4 shown, the lower end of the fitting pipe portion 13 extends to the first water inlet 121. A flow splitting port 130 penetrating the fitting pipe portion 13 in the radial direction of the fitting pipe portion 13 is formed in the lower part of the fitting pipe portion 13. The flow splitting port 130 is communicated with the regional water outlet 122 and is at least partially located below the support platform 131.

[0066] For example, the lower end of the fitting pipe portion 13 extends downward to the first water inlet 121, and the cross-sectional shape of the part of the lower part of the fitting pipe portion 13 where the flow splitting port 130 is formed can be two-thirds of an annular shape. For example, the flow splitting port 130 is communicated with the regional water outlet 122, and a part of the flow splitting port 130 is located below the support platform 131; or, the flow splitting port 130 is communicated with the regional water outlet 122, and the flow splitting port 130 is entirely located below the support platform 131. Water flow can flow from the first water outlet to the flow splitting port 130 and then flow to the regional spray arm 30.

[0067] In this embodiment, by extending the lower end of the fitting pipe portion 13 to the first water inlet 121, the connection mode between the water inlet and the fitting pipe portion 13 can be effectively simplified, thereby effectively reducing the possibility of water leakage at the connection between the water inlet and the fitting pipe portion 13, and further effectively improving the reliability; by forming a flow splitting port 130 penetrating the fitting pipe portion 13 in the radial direction of the fitting pipe portion 13 in the lower part of the fitting pipe portion 13, the flow splitting port 130 is communicated with the regional water outlet 122 and is at least partially located below the support platform 131, the resistance of the water flow in the flow splitting chamber 101 can be effectively reduced, so that the water flow is more smooth, and further the water pressure and water flow speed can be effectively improved.

[0068] In an embodiment of the present utility model, as Figure 4As shown, the diversion port 130 is formed by a depression upward from the lower end edge of the mating pipe portion 13. For example, a depression upward from the lower end edge of the mating pipe portion 13 is formed by processes such as injection molding or stamping. The diversion port 130 of this embodiment is formed by a depression upward from the lower end edge of the mating pipe portion 13, which can effectively simplify the manufacturing process, thus effectively reducing the manufacturing difficulty and saving costs. In addition, the size of the depression range and the shape of the depression can also be adjusted according to actual needs, so as to effectively improve flexibility.

[0069] In an embodiment of the present utility model, as Figure 1 , Figure 6 and Figure 8 shown, the filter element 10 is also formed with a second water inlet 102 and a third water inlet 123 arranged at intervals. The spraying assembly 100 further includes a second spray arm 40 and a top spraying device 50. The second spray arm 40 is arranged on the upper side of the first spray arm 20 and is communicated with the second water inlet 102. The top spraying device 50 is arranged on the upper side of the second spray arm 40 and is communicated with the third water inlet 123.

[0070] In a specific example, as Figure 6 shown, the first water inlet 121, the second water inlet 102 and the third water inlet 123 are arranged at intervals. Further, the second water inlet 102 is formed on the lower side of the filter element 10, and the third water inlet 123 is formed on the lower side of the support 12. For example Figure 8 shown, the spraying assembly 100 further includes a water cup 60. The water cup 60 is provided with independent first water holes 61, second water holes 62 and third water holes 63. The first water hole 61 is connected to the first water inlet 121, the second water hole 62 is connected to the second water inlet 102, and the third water hole is connected to the third water inlet 123. Thus, the water flows in the first water inlet 121, the second water inlet 102 and the third water inlet 123 can be made not to interfere with each other.

[0071] In this embodiment, by further forming a second water inlet 102 and a third water inlet 123 arranged at intervals on the filter element 10, the water flows in the first water inlet 121, the second water inlet 102 and the third water inlet 123 can be made independent and non-interfering with each other, thereby effectively ensuring the flow efficiency of the water flows in the first water inlet 121, the second water inlet 102 and the third water inlet 123.

[0072] For example Figure 1 shown, the second spray arm 40 can be arranged in a long strip shape and is located on the upper side of the first spray arm 20. The second spray arm 40 is provided with second spray holes 41. Further, the number of the second spray holes 41 can be multiple. For example, the number of the second spray holes 41 can be two, three, four, five, six or more. The multiple second spray holes 41 are respectively arranged on both sides of the second spray arm 40.

[0073] A second water outlet pipe 42 is also provided in the second spray arm 40. One end of the second water outlet pipe 42 is connected to the second water inlet 102, and the other end of the second water outlet pipe 42 is connected to the second spray arm 40. Water flow can flow in from the second water inlet 102 and flow to the second spray arm 40 and be ejected upward from the second spray holes 41. Further, the second spray arm 40 can perform rotary spraying.

[0074] For example Figure 1 As shown, the top spray device 50 is arranged on the upper side of the second spray arm 40. A third water outlet pipe 51 is provided in the top spray device 50. One end of the third water outlet pipe 51 is connected to the third water inlet 123, and the other end of the third water outlet pipe 51 is connected to the top spray device 50. Water flow can flow in from the third water inlet 123 and flow to the top spray device 50 and be ejected downward from the top spray device 50.

[0075] For example, the spraying assembly 100 can independently control the first spray arm 20 and the area spray arm 30 to work; or, the spraying assembly 100 can independently control the second spray arm 40 to work; or, the spraying assembly 100 can independently control the top spray device 50 to work. In addition, the spraying assembly 100 can control any two of the foregoing three to work simultaneously, and the spraying assembly 100 can also control the foregoing three to work simultaneously.

[0076] In this embodiment, by providing the second spray arm 40 and the top spray device 50 in the spraying assembly 100, the second spray arm 40 is arranged on the upper side of the first spray arm 20 and communicated with the second water inlet 102, and the top spray device 50 is arranged on the upper side of the second spray arm 40 and communicated with the third water inlet 123, not only making the water flows in the first spray arm 20, the second spray arm 40 and the top spray device 50 not interfere with each other, thereby effectively improving the spraying efficiency of the water flow, but also effectively improving the spraying effect of the water flow, thereby effectively improving the cleaning efficiency.

[0077] In an embodiment of the present utility model, as Figure 4 shown, ribs are formed on the outer peripheral surface of the first connecting pipe portion 22. The ribs extend circumferentially along the first connecting pipe portion 22 into a ring shape, and the number of ribs is one or a plurality arranged at intervals in the up and down direction.
