[0044] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0045] Please refer to the following Figure 1-10 A spray arm assembly 100 according to an embodiment of the present invention is described.

[0046] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 10 According to the spray arm assembly 100 of the first embodiment of the present utility model, the spray arm assembly 100 includes: a spray arm 10 and a water blocking member 20.

[0047] Specifically, the spray arm 10 is suitable for communicating with the water pipe 210, and the spray arm 10 is formed with a spray hole 11; the water blocking member 20 is movably connected to the spray arm 10 between a first position and a second position, and the water blocking member 20 includes a water blocking portion 21. When the water blocking member 20 is in the first position, the water blocking portion 21 blocks the spray hole 11, and when the water blocking member 20 is in the second position, the water blocking portion 21 opens the spray hole 11.

[0048] Before cleaning the dish 2000 to be cleaned, the water retaining member 20 is in the first position, and then the dish 2000 to be cleaned is installed in conjunction with the spray arm assembly 100. During the process of installing the dish 2000 to be cleaned and the spray arm assembly 100 until the installation is completed, the water retaining member 20 moves from the first position to the second position. At this time, the water retaining member 21 opens the spray hole 11. When the spray arm assembly 100 is running, water flows to the spray arm 10 through the water pipe 210, and then the water flows from the nozzle to the dish 2000 to be cleaned.

[0049] The spray arm assembly 100 of the present invention is provided with a water retaining member 20 on the spray arm 10, and the water retaining member 20 switches between a first position and a second position to realize the opening or closing of the spray hole 11. Therefore, when the water retaining member 21 opens the spray hole 11, the spray arm assembly 100 will spray water from the spray hole 11. Compared with the solution in the prior art that the spray arm 10 cannot control the opening and closing of the spray hole 11, the spray arm assembly 100 of the present application can control whether the spray arm assembly 100 sprays water through the water retaining member 21, thereby avoiding the waste of water resources, improving the utilization rate of water resources, and effectively reducing the cost of use. At the same time, if there are no utensils 2000 to be cleaned placed on the spray arm 10, the spray hole 11 is closed, which can ensure the water pressure in the water pipe 210, thereby ensuring the cleaning effect of the dishwasher in cleaning other utensils 2000 to be cleaned.

[0050] According to the spray arm assembly 100 of the embodiment of the present invention, a water retaining member 20 is provided on the spray arm 10. The water retaining member 20 can control the opening and closing of the spray hole 11, thereby avoiding the waste of water resources, improving the utilization rate of water resources, and effectively reducing the use cost.

[0051] According to some embodiments of the present invention, referring to Figure 2 、 Figure 3 、 Figure 4 and Figure 10 A water flow channel 12 is formed in the spray arm 10, and the spray hole 11 is connected to the water flow channel 12. The water retaining portion 21 is located in the water flow channel 12 and between the spray hole 11 and the water inlet end 13 of the spray arm 10. Therefore, the water retaining portion 21 is reasonably positioned, and the opening and closing of the spray hole 11 can be controlled by the water retaining portion 21, so that water can be sprayed only when the spray arm 10 is placed with the container 2000 to be cleaned, thereby avoiding water waste.

[0052] For example, Figure 2 、 Figure 3 、 Figure 4 and Figure 10 As shown, a water flow channel 12 extending axially along the spray arm 10 is formed in the spray arm 10 , the lower end of the water flow channel 12 is connected to the water pipe 210 , the upper end of the water flow channel 12 is connected to the spray hole 11 , and the water retaining portion 21 extends into the water flow channel 12 .

[0053] According to some optional embodiments of the present invention, referring to Figure 2 、 Figure 3 and Figure 4 The water blocking member 20 includes a device provided along a first direction (such as Figure 4 The spray arm 10 is provided with a rotating shaft 22 extending in the front-to-back direction (as shown), and a shaft hole 14 corresponding to the rotating shaft 22 is provided on the spray arm 10. The rotating shaft 22 is rotatably engaged in the shaft hole 14, and the water retaining portion 21 is provided on the rotating shaft 22. As a result, the cooperation between the rotating shaft 22 and the shaft hole 14 is simple, thereby ensuring that the water retaining portion 21 can normally open and close the spray hole 11. At the same time, the structure of the rotating shaft 22 and the shaft hole 14 is simple, thereby facilitating the processing of the spray arm assembly 100.

[0054] For example, Figure 2 、 Figure 3 and Figure 4 As shown, the water retaining member 20 is provided with a rotating shaft 22 extending in the front-to-back direction. The rotating shaft 22 is provided with a water retaining portion 21 at a middle position in the front-to-back direction. The water retaining portion 21 is in the shape of a circular plate. When the water retaining member 20 is in the first position, the water retaining portion 21 blocks the spray hole 11. When the water retaining member 20 moves from the first position to the second position, the rotating shaft 22 rotates within the shaft hole 14 until the water retaining member 20 moves to the second position, at which point the water retaining portion 21 opens the spray hole 11.

[0055] According to some optional embodiments of the present invention, referring to Figure 2 、 Figure 3 and Figure 4 There are two shaft holes 14, which are respectively arranged on the first direction (such as Figure 3 On opposite sides of the spray arm 10 (in the front and rear directions shown), a mounting opening 15 is formed on the peripheral wall of the spray arm 10, which passes through the spray arm 10 and is connected to the water flow channel 12. The mounting opening 15 extends along the circumference of the spray arm 10, and the mounting opening 15 is at both ends of the circumference of the spray arm 10 (as shown in FIG. Figure 3 The front and rear ends of the mounting opening 15 shown extend to communicate with the two axial holes 14 respectively.

[0056] In this way, the two shaft holes 14 allow both ends of the rotating shaft 22 to pass through the shaft holes 14, thereby facilitating the mating installation of the rotating shaft 22 and the shaft hole 14. At the same time, the structure of the mounting opening 15 is reasonable, thereby ensuring that the rotating shaft 22 can pass through the mounting opening 15 and mate with the shaft hole 14. Furthermore, the mounting opening 15 is connected to the water flow channel 12, thereby ensuring that the water retaining portion 21 can extend into the water flow channel 12 to block the spray hole 11, thereby ensuring the water retaining function of the water retaining member 20.

[0057] For example, Figure 2 、 Figure 3 and Figure 4As shown, the two axial holes 14 are respectively arranged on the front and rear sides of the spray arm 10, and a mounting opening 15 is formed on the left peripheral wall of the spray arm 10, which passes through the spray arm 10 in the front-to-back direction. The mounting opening 15 extends along the circumference of the spray arm 10, and the front and rear ends of the mounting opening 15 are respectively connected to the two axial holes 14.

[0058] According to some embodiments of the present invention, referring to Figure 2 、 Figure 3 and Figure 4 The water retaining member 20 includes a driving portion 23, the driving portion 23 is arranged on the outside of the spray arm 10, and one end of the driving portion 23 (such as Figure 4 The left end of the driving part 23 shown in FIG. 2 is connected to the rotating shaft 22, and the other end of the driving part 23 (as shown in FIG. Figure 4 The right end of the driving portion 23 shown in FIG. 2 is along the second direction (as shown in FIG. Figure 4 The left and right directions shown in FIG) extend away from the rotation axis 22, and the first direction (as shown in FIG) extends away from the rotation axis 22. Figure 4 The front-to-rear direction shown in the figure) intersects with the second direction, and the water blocking member 20 is configured to rotate between the first position and the second position under the action of the external force of the driving portion 23.

[0059] In this way, the driving part 23 is connected to the rotating shaft 22, and the rotation of the driving part 23 can drive the rotating shaft 22 to rotate, thereby enabling the water retaining member 20 to move between the first position and the second position. At the same time, the driving part 23 is arranged on the outside of the spray arm 10, so that it is convenient for the external structure to apply force to the driving part 23, for example, the utensil 2000 to be cleaned applies pressure to the driving part 23, which makes it convenient for the driving part 23 to drive the rotating shaft 22 to rotate.

[0060] For example, Figure 2 、 Figure 3 and Figure 4 As shown, the driving part 23 is located on the outside of the spray arm 10, the left end of the driving part 23 is connected to the rotating shaft 22, and the right end of the driving part 23 extends to the right along the left-right direction. When the utensil 2000 to be cleaned is matched with the spray arm assembly 100, the utensil 2000 to be cleaned presses the driving part 23, thereby realizing the rotation of the water retaining part 20 from the first position to the second position.

[0061] According to some optional embodiments of the present invention, referring to Figure 2 、 Figure 3 and Figure 4 , when the water retaining member 20 is in the first position, in the second direction (such as Figure 4 In the left and right directions shown in FIG, the driving portion 23 is away from one end of the rotating shaft 22 (as shown in FIG. Figure 4 The right end of the driving portion 23 shown in FIG. 1 is beyond the edge of one side of the spray arm 10 (as shown in FIG. Figure 4 The right side edge of the spray arm 10 shown in FIG), when the water retaining member 20 is in the second position, the driving portion 23 is away from one end of the rotating shaft 22 (such as Figure 4The left end of the driving portion 23 shown in FIG. 1 is located at both side edges of the spray arm 10 in the second direction (as shown in FIG. Figure 4 between the left and right edges of the spray arm 10 as shown).

[0062] In this way, the water stop 20 is in the first position, and the end of the driving part 23 away from the rotating shaft 22 exceeds the spray arm 10, so that the external structure can apply a force to the driving part 23, and then the rotating shaft 22 can be ensured to rotate in the shaft hole 14, so that the control part can be switched between the first position and the second position. At the same time, the water stop 20 is in the second position, and the end of the driving part 23 away from the rotating shaft 22 does not exceed the edge of the spray arm 10 in the second direction, so that the utensil 2000 to be cleaned can be matched with the spray arm assembly 100, and then the water stop 20 can be rotated to the second position, thereby ensuring the cleaning effect of the utensil 2000 to be cleaned.

[0063] For example, Figure 2 、 Figure 3 and Figure 4 As shown, when the water retaining member 20 is in the first position, the right end of the driving portion 23 exceeds the right edge of the spray arm 10. When the water retaining member 20 is in the second position, the right end of the driving portion 23 is located between the two side edges of the spray arm 10 in the left and right directions.

[0064] According to some embodiments of the present invention, referring to Figure 2 、 Figure 3 and Figure 4 There are two driving parts 23, and the two driving parts 23 are respectively connected to the rotating shaft 22 in the first direction (such as Figure 4 Thus, the two driving parts 23 can drive the rotating shaft 22 at both ends of the rotating shaft 22, thereby ensuring the smoothness of the movement of the rotating shaft 22 in the shaft hole 14, and further ensuring the stability of the rotation of the water retaining member 20.

[0065] According to some embodiments of the present invention, referring to Figure 2 、 Figure 3 and Figure 4 The water stopper 20 further includes: a first limiting portion 241 and a second limiting portion 242. Specifically, the first limiting portion 241 is connected to the rotating shaft 22. When the water stopper 20 is in the first position, the first limiting portion 241 abuts against the outer surface of the spray arm 10 to limit the water stopper 20 from rotating in a direction away from the second position. The second limiting portion 242 is connected to the rotating shaft 22. When the water stopper 20 is in the second position, the second limiting portion 242 abuts against the outer surface of the spray arm 10 to limit the water stopper 20 from rotating in a direction away from the first position.

[0066] In this way, a first limiting portion 241 is set to limit the rotation angle of the water retaining member 20 at the first position, thereby preventing the water retaining member 20 from continuing to rotate and causing the water retaining member 21 to be unable to block the spray hole 11. A second limiting portion 242 is set to limit the rotation angle of the water retaining member 20 at the second position, thereby preventing the water retaining member 20 from continuing to rotate and causing the water retaining member 21 to block the spray hole 11.

[0067] According to some optional embodiments of the present invention, referring to Figure 2 、 Figure 3 and Figure 4 The water retaining member 20 includes a baffle 24, the baffle 24 and the driving portion 23 are respectively arranged on the second direction (such as Figure 4 On the opposite sides of the left and right directions shown in FIG, one end of the baffle 24 (as shown in FIG. Figure 4 The upper end of the baffle 24 shown in FIG. 2 is connected to the rotating shaft 22, and the other end (as shown in FIG. Figure 4 The lower end of the baffle 24 shown in FIG. Figure 4 The third direction extends away from the first direction (as shown in the vertical direction) and extends away from the rotation axis 22. Figure 4 The front-rear direction shown in FIG. 2 ) and the second direction intersect each other, wherein the baffle 24 has an edge on one side away from the rotating shaft 22 in the third direction (as shown in FIG. Figure 4 The lower edge of the baffle 24 shown in FIG. 2 is formed as a first limiting portion 241, and the baffle 24 faces one side edge of the rotating shaft 22 in the third direction (as shown in FIG. Figure 4 The upper edge of the baffle 24 shown is formed as a second limiting portion 242.

[0068] In this way, a baffle 24 is provided, and the baffle 24 is connected to the rotating shaft 22, thereby ensuring that the baffle 24 and the rotating shaft 22 can rotate synchronously, and further ensuring that the baffle 24 can follow the rotation of the rotating shaft 22 to limit the rotation angle of the water retaining member 20. At the same time, a first limiting portion 241 and a second limiting portion 242 are provided on the baffle 24, eliminating the need to additionally provide the first limiting portion 241 and the second limiting portion 242, thereby improving the functional integration of the baffle 24. In addition, the relative position of the baffle 24 and the driving portion 23 is reasonable, thereby ensuring that the external structure can normally apply a force to the driving portion 23, and ensuring that the baffle 24 can limit the rotation angle of the water retaining member 20.

[0069] For example, Figure 2 、 Figure 3 and Figure 4 As shown, the baffle 24 is arranged on the left side of the rotating shaft 22, and the baffle 24 extends in the up and down directions. The upper end of the baffle 24 is connected to the rotating shaft 22, and the lower end of the baffle 24 extends downward. The lower end of the baffle 24 forms a first limiting portion 241, and the upper end of the baffle 24 forms a second limiting portion 242.

[0070] According to some embodiments of the present invention, referring to Figure 2 、 Figure 3 and Figure 4 The first direction is the front-back direction, the second direction is the left-right direction, and the third direction is the up-down direction.

[0071] According to some embodiments of the present invention, referring to Figure 2 、 Figure 3 and Figure 4 The water retaining member 20 includes a baffle 24, the baffle 24 is connected to the shaft 22, and the baffle 24 and the driving portion 23 are respectively arranged on the shaft 22 in the second direction (such as Figure 4 On opposite sides of the left and right directions (as shown), the water retaining member 20 is configured to be suitable for driving the water retaining member 20 to move toward the first position under the action of the gravity of the baffle 24.

[0072] In this way, there is no need to apply additional force, and the baffle 24 can rely on its own gravity to drive the water baffle 20 to the first position. Therefore, each time the spray arm assembly 100 cleans the utensil 2000 to be cleaned, the utensil 2000 to be cleaned is separated from the spray arm assembly 100, and the baffle 24 drives the water baffle 20 to the first position under the action of its own gravity, which can facilitate the next placement of the utensil 2000 to be cleaned on the spray arm assembly 100, thereby saving the step of resetting the water baffle 20 to the first position, and effectively improving the user experience.

[0073] According to some embodiments of the present invention, referring to Figure 2 、 Figure 3 and Figure 4 The spray arm assembly 100 includes: a clamping member 30, the clamping member 30 includes a clamping body 31 and an elastic arm 32 connected to the clamping body 31, the clamping body 31 is fixed to the spray arm 10, and the clamping body 31 and the elastic arm 32 are suitable for clamping on the two side surfaces of the side wall of the container 2000 to be cleaned, so that the spray arm 10 is formed with one end of the spray hole 11 (such as Figure 3 The upper end of the spray arm 10 shown extends into the container 2000 to be cleaned.

[0074] In this way, the clamping body 31 is directly fixed to the spray arm 10, which facilitates the fixation of the clamping member 30 and improves the installation efficiency of the clamping member 30. At the same time, the clamping body 31 cooperates with the elastic arm 32 to fix the utensil 2000 to be cleaned. This fixing form is simple and easy to operate, thereby improving the user experience.

[0075] Furthermore, the spray arm 10 is extended into the interior of the vessel 2000 to be cleaned, thereby ensuring that the spray arm 10 can clean deep-mouthed vessels, such as deep-mouthed cups or deep-mouthed dishes. Compared with the prior art solution of using a cleaning enhancement structure to clean deep-mouthed vessels, the spray arm assembly 100 of the present application is directly extended into the interior of the vessel 2000 to be cleaned, thereby effectively ensuring the cleaning effect. At the same time, there is no need to use a higher water pressure to ensure the cleaning effect, thereby reducing power consumption and further reducing the cost of use.

[0076] For example, Figure 2 、 Figure 3 and Figure 4 As shown, the clamping body 31 is fixed on the spray arm 10, the clamping body 31 is clamped on the inner surface of the vessel 2000 to be cleaned, and the elastic arm 32 is clamped on the outer surface of the vessel 2000 to be cleaned. The upper end of the spray arm 10 forms a spray hole 11, and the upper end of the spray arm 10 extends into the interior of the vessel 2000 to be cleaned.

[0077] According to some embodiments of the present invention, referring to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The elastic arm 32 extends along the extension direction of the spray arm 10, and one end of the elastic arm 32 (such as Figure 5 The lower end of the elastic arm 32 shown in FIG. 3 is fixed to the clamping body 31, and the other end of the elastic arm 32 (as shown in FIG. Figure 5 The upper end of the elastic arm 32 is formed at a protruding clamping protrusion 321 facing the clamping body 31 , and the clamping protrusion 321 is suitable for abutting against the outer surface of the dish 2000 to be cleaned.

[0078] In this way, the elastic arm 32 is fixed to the clamping body 31, making the clamping member 30 an integral unit, thereby ensuring the strength of the clamping member 30 and effectively preventing damage to the clamping member 30. At the same time, no additional fixing parts are required, thereby reducing the number of parts and effectively lowering production costs. In addition, the clamping protrusion 321 is provided on the elastic arm 32, which not only facilitates the clamping protrusion 321 to clamp the container 2000 to be cleaned, but also ensures the reliability of the elastic arm 32 in clamping the container 2000 to be cleaned, thereby effectively preventing the container 2000 to be cleaned from separating from the clamping member 30.

[0079] For example, Figure 2 、 Figure 3 and Figure 4 As shown, the elastic arm 32 extends in the up-down direction, the lower end of the elastic arm 32 is fixed to the clamping body 31 , and the upper end of the elastic arm 32 is formed with a clamping protrusion 321 protruding toward the clamping body 31 .

[0080] According to some optional embodiments of the present invention, referring to Figure 2 and Figure 5 , at one end of the elastic arm 32 (such as Figure 5 The lower end of the elastic arm 32 shown in the figure is directed toward the clamping protrusion 321, and the elastic arm 32 extends along an arc line that is convex away from the spray arm 10.

[0081] In this way, the extension form of the elastic arm 32 is limited, thereby ensuring that the elastic arm 32 can normally deform elastically relative to the clamping body 31. At the same time, the elastic arm 32 protrudes away from the spray arm 10. When the dish 2000 to be cleaned is completely placed between the elastic arm 32 and the clamping body 31, the space between the elastic arm 32 and the clamping body 31 can provide a space for the end of the dish 2000 to be cleaned, thereby ensuring that the spray arm assembly 100 can adapt to a variety of dishes 2000 to be cleaned, thereby effectively improving the versatility of the spray arm assembly 100. For example, Figure 2 and Figure 5 As shown, in the direction from bottom to top, the elastic arm 32 extends along an arc that is convex to the right.

[0082] According to some embodiments of the present invention, referring to Figure 2 and Figure 5 The other end of the clamping protrusion 321 toward the elastic arm 32 (such as Figure 5 The upper end edge of the clamping protrusion 321 shown in FIG. 3 is formed as a guide slope 322, which is formed at one end of the elastic arm 32 (as shown in FIG. Figure 5 The lower end of the elastic arm 32 shown in FIG. Figure 5 The guide slope 322 gradually extends away from the spray arm 10 in an inclined direction (in the direction of the upper end of the elastic arm 32 shown in FIG. 1 ).

[0083] In this way, the guide inclined surface 322 is provided, and when the dish 2000 to be cleaned is assembled with the spray arm assembly 100, the moving direction of the dish 2000 to be cleaned can be guided, thereby ensuring that the dish 2000 to be cleaned is accurately moved to the appropriate position. At the same time, the friction between the surface of the dish 2000 to be cleaned and the elastic arm 32 can be reduced, thereby ensuring smooth sliding of the dish 2000 to be cleaned relative to the elastic arm 32.

[0084] For example, Figure 2 and Figure 5 As shown, the upper side surface of the upper end of the clamping protrusion 321 is formed as a guide slope 322, and in the direction from bottom to top, the guide slope 322 extends obliquely to the right.

[0085] According to some embodiments of the present invention, referring to Figure 2 、 Figure 3 and Figure 5The clamping body 31 is cylindrical and extends in the direction of the spray arm 10, and is sleeved on the outside of the spray arm 10. As a result, the clamping body 31 has a simple structure and is easy to process, thereby improving the processing efficiency of the clamping member 30. At the same time, the clamping body 31 and the spray arm 10 are simply matched, which facilitates the installation of the clamping member 30 and the spray arm 10.

[0086] According to some embodiments of the present invention, referring to Figure 2 、 Figure 4 and Figure 5 The clamping body 31 is provided with an assembly avoidance hole 311 for avoiding the water retaining member 20. The assembly avoidance hole 311 penetrates the side wall of the clamping body 31 away from the elastic arm 32 along the radial direction of the clamping body 31 (such as Figure 5 The left side wall of the clamping body 31 shown in the figure), the assembly avoidance hole 311 extends in a long strip shape along the axial direction of the clamping body 31. Therefore, the provision of the assembly avoidance hole 311 can facilitate the coordinated installation of the water retaining member 20 and the spray arm 10, thereby saving installation time and improving installation efficiency. At the same time, the shape of the assembly avoidance hole 311 is simple, which can be easily processed and can effectively improve the production efficiency of the clamping member 30. Furthermore, the extended shape of the assembly avoidance hole 311 is limited, thereby ensuring that the clamping body 31 can avoid the water retaining member 20 within a larger range, thereby facilitating the installation of the water retaining member 20 and the spray arm 10.

[0087] For example, Figure 2 、 Figure 4 and Figure 5 As shown, an assembly avoidance hole 311 is provided on the left side wall of the clamping body 31. The assembly avoidance hole 311 penetrates the left side wall of the clamping body 31 in the left-right direction and extends in a long strip shape in the up-down direction.

[0088] According to some embodiments of the present invention, referring to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The clamping body 31 is formed with a limiting hole 312, which is arranged on both sides of the assembly avoidance hole 311 in the circumferential direction of the clamping body 31, and the limiting hole 312 is at one end of the clamping body 31 in the axial direction (such as Figure 5 The lower end of the limiting hole 312 shown in FIG) is connected to the assembly avoidance hole 311, the water retaining member 20 includes a rotating shaft 22, the water retaining portion 21 is provided on the rotating shaft 22, and both ends of the rotating shaft 22 (such as Figure 4 The front end and the rear end of the rotating shaft 22 are respectively fitted into the two limiting holes 312.

[0089] In this way, the provision of the limiting hole 312 can remind whether the water retaining member 20 and the spray arm 10 are properly installed, thereby effectively preventing the water retaining portion 21 of the water retaining member 20 from colliding with the inner wall of the water flow channel 12 and being damaged. At the same time, the limiting hole 312 is connected to the assembly avoidance hole 311, thereby ensuring that the water retaining member 20 can be matched with the limiting hole 312 after passing through the assembly avoidance hole 311, thereby ensuring that the water retaining portion 21 of the water retaining member 20 can block the spray hole 11. Furthermore, the two ends of the rotating shaft 22 are respectively matched in the limiting holes 312, thereby ensuring that both ends of the rotating shaft 22 can be limited, thereby effectively preventing the rotating shaft 22 from being separated from the shaft hole 14.

[0090] For example, Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, limiting holes 312 are formed on both the front and rear sides of the clamping body 31 , the lower ends of the limiting holes 312 are connected to the assembly avoidance holes 311 , and the front and rear ends of the rotating shaft 22 are respectively fitted in the corresponding limiting holes 312 .

The number of spray arm assemblies 100 can be one or multiple spray arm assemblies 100 spaced apart along the extension direction of the water pipe 210. In other words, the number of spray arm assemblies 100 can be one, two, or three or more. The water inlet end 13 of the spray arm 10 is connected to the water pipe 210.

[0092] For example, Figure 1 、 Figure 2 and Figure 3 As shown, a water pipe 210 is provided on the bowl basket body 200 , and there are four spray arm assemblies 100 , which are arranged at intervals along the extension direction of the water pipe 210 .

The baffle 24 is arranged on the left side of the rotating shaft 22, and the baffle 24 and the driving portion 23 are arranged on opposite sides in the left-right direction. The upper end of the baffle 24 is connected to the rotating shaft 22, and the lower end of the baffle 24 extends downward. The lower end of the baffle 24 forms a first limiting portion 241, and the upper end of the baffle 24 forms a second limiting portion 242.

[0100] The water stop member 20 is movably connected to the spray arm 10 between a first position and a second position. When the water stop member 20 is in the first position, the water stop portion 21 blocks the spray hole 11, and the right end of the driving portion 23 extends beyond the right end edge of the spray arm 10. When the water stop member 20 is in the second position, the water stop portion 21 opens the spray hole 11, and the driving portion 23 is located between the left end edge and the right end edge of the spray arm 10.

[0101] The clamping member 30 includes a clamping body 31 and an elastic arm 32. The clamping body 31 is cylindrical and extends in the vertical direction, and is sleeved on the outer side of the spray arm 10.

In the direction from bottom to top, the guide slope 322 gradually extends away from the spray arm 10.

[0103] When assembling the spray wall assembly, first put the clamping body 31 of the clamping part 30 on the spray arm 10, and the lower end of the assembly avoidance hole 311 needs to be lower than the installation port 15, and then move the water retaining part 20 from left to right until the rotating shaft 22 of the water retaining part 20 passes through the assembly avoidance hole 311 and the installation port 15 in turn and enters the shaft hole 14. When the water retaining part 21 blocks the spray hole 11 and the two ends of the rotating shaft 22 pass through the shaft holes 14 on the front and rear sides, the cooperation between the water retaining part 20 and the spray arm 10 is completed, and then move the clamping part 30 downward until the front and rear ends of the rotating shaft 22 are located in the limiting holes 312 on the front and rear sides. At this time, the assembly of the spray arm assembly 100 is completed.

[0104] When using a dishwasher to wash a dish 2000, the dish 2000 is first placed on the spray arm assembly 100, and the water retaining member 20 is at the first position. Figure 6 and Figure 7As shown, the water retaining portion 21 blocks the spray hole 11, and the first limiting portion 241 abuts against the surface of the spray arm 10. When the dish 2000 to be cleaned is moved downward, the end of the open side of the dish 2000 to be cleaned contacts the guide inclined surface 322, and then the dish 2000 to be cleaned passes through the clamping protrusion 321.
