[0035] 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.

[0036] Reference below Figure 1-Figure 7 The spray arm assembly 100 according to the first embodiment of the present invention is described.

[0037] According to the spray arm assembly 100 of the first embodiment of the present utility model, Figure 1 and Figure 2 As shown, the spray arm assembly 100 includes a spray arm 10 and a trigger member 20 .

[0038] Specifically, if Figure 3-Figure 7 As shown, a spray hole 11 is formed at one end of the spray arm 10, and a trigger member 20 is arranged on the outside of the spray arm 10. The trigger member 20 is movable between a first position and a second position relative to the spray arm 10. In the first position, the trigger member 20 blocks the spray hole 11, and in the second position, the trigger member 20 opens the spray hole 11.

[0039] It is understandable that when the dishwasher is in operation, the amount of water used to wash the dishes 200 in the dishwasher is certain. At the same time, the power used to drive the water flow in the dishwasher is also certain. When multiple spray arms 10 in the dishwasher spray water through the spray holes 11, each spray arm 10 will divert a part of the water flow and water pressure.

[0040] After the tableware 200 is placed in the dishwasher, the tableware 200 may not fill the dishwasher. In the position where the tableware 200 is not covered, the water sprayed by the spray arm 10 cannot play a role in cleaning.

[0041] In this embodiment, the water spraying state of the spray arm 10 is controlled by the trigger member 20. During the operation of the dishwasher, after the tableware 200 is placed in the dishwasher, the dishwasher can be controlled to spray water on the tableware 200 only when the spray hole 11 can act on the tableware 200. In this way, the diversion and pressure distribution of the water flow by the spray hole 11 that does not participate in the cleaning process can be reduced, thereby improving the cleaning effect. As a result, the cleaning range of the dishwasher can be adapted to the number, position and size of the tableware 200 placed in the dishwasher by the user, thereby meeting the differentiated cleaning needs of the user.

[0042] By arranging the trigger member 20 on the outside of the spray arm 10, it can be understood by those skilled in the art that there is more arrangement space on the outside of the spray arm 10, and the matching relationship between the trigger member 20 and the spray arm 10 is relatively simple. During the design process, it is easier to arrange the trigger member 20 on the spray arm 10. During the production process, the operator has more operating space, which can reduce the difficulty of production.

[0043] It should be noted that the spray arm assembly 100 of the present invention can be used on a dishwasher, and can also be used on other washing equipment that can spray water.

[0044] According to the spray arm assembly 100 of the first embodiment of the present invention, by controlling the water spraying state of the spray arm 10, during the operation of the dishwasher, the spray hole 11 can be opened when there are dishes 200 to be washed at the position corresponding to the spray hole 11, thereby improving the water flow utilization rate during the cleaning process, thereby improving the cleaning effect and meeting the user's differentiated cleaning needs for the dishes 200. By arranging the trigger member 20 on the outside of the spray arm 10, the design difficulty and production difficulty of the spray arm assembly 100 can be reduced.

[0045] In some embodiments of the present invention, the trigger member 20 is rotatably connected to the spray arm 10. That is, during operation of the dishwasher, when the spray arm 10 needs to spray water, the trigger member 20 rotates from the first position to the second position. It is understood that the rotating pair is easier to trigger and has higher reliability. The rotatable connection between the trigger member 20 and the spray arm 10 can improve the reliability of the spray arm assembly 100 during operation, thereby improving the reliability of the dishwasher during operation.

[0046] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the trigger member 20 has a blocking end 21 and a trigger end 22 at its longitudinal ends. The middle portion of the trigger member 20 is rotatably connected to the spray arm 10. When the trigger member 20 is in the first position, the blocking end 21 blocks the spray hole 11. The trigger end 22 is configured to rotate the trigger member 20 from the first position to the second position under the action of an external force. This simplifies the structure of the spray arm assembly 100, further reducing the design and production difficulties of the spray arm assembly 100.

[0047] Among them, the external force can be provided by a driving member separately provided on the dishwasher, and the external force can also be provided by the tableware 200 loaded into the dishwasher. During the operation of the dishwasher, the tableware 200 can press against the trigger end 22, so that the trigger member 20 gradually rotates from the first position to the second position. At the same time, the blocking end 21 gradually opens the spray hole 11. In this way, the structure of the dishwasher is relatively simple, and the spray hole 11 can be opened when the tableware 200 is placed in the position of the spray arm assembly 100, thereby accurately cleaning the tableware 200 and meeting the differentiated cleaning needs of users.

[0048] In some embodiments of the present invention, Figure 3 and Figure 6 As shown, a blocking protrusion 211 is formed on the side of the blocking end 21 facing the spray hole 11. In the first position, at least a portion of the blocking protrusion 211 extends into the spray hole 11 to block the spray hole 11. In other words, in the first position, the blocking protrusion 211 may partially extend into the spray hole 11, or the blocking protrusion 211 may fully extend into the spray hole 11.

[0049] By providing the blocking protrusion 211 , the blocking effect of the blocking end 21 on the spray hole 11 can be improved, thereby improving the reliability of the spray arm assembly 100 during operation.

[0050] In some embodiments of the present invention, Figure 3 and Figure 6 As shown, the cross-sectional dimensions of the blocking protrusion 211 gradually decrease in the protruding direction of the blocking protrusion 211. Thus, during the rotation of the trigger member 20 from the first position to the second position, the end of the blocking protrusion 211 with the smaller cross-sectional dimension first extends into the spray hole 11, and then the blocking protrusion 211 gradually extends into the spray hole 11. The tapered surface of the blocking protrusion 211 can guide the insertion process, and the tapered surface of the blocking protrusion 211 can abut against the edge of the spray hole 11 over a wider range, thereby further improving the reliability of the blocking end 21 in blocking the spray hole 11 and further improving the reliability of the spray arm assembly 100 during operation.

[0051] In some embodiments of the present invention, Figure 2-Figure 4 As shown, the spray arm assembly 100 further includes a reset member 30, which is used to always drive the trigger member 20 to rotate from the second position toward the first position.

[0052] When the spray arm assembly 100 finishes the cleaning work, the tableware 200 is removed from the spray arm assembly 100. Under the action of the reset member 30, the trigger member 20 rotates from the second position toward the first position until the blocking end 21 blocks the spray hole 11. The spray arm assembly 100 can be ready for the next cleaning. In this way, the trigger member 20 can be automatically reset on the spray arm 10, thereby improving the user experience.

[0053] Preferably, the reset member 30 is a torsion spring, which is arranged between the trigger member 20 and the spray arm 10. The torsion spring can reset the trigger member 20 from the second position to the first position, and the torsion spring is easy to arrange, which can further reduce the design difficulty and production difficulty of the spray arm assembly 100.

[0054] In some embodiments of the present invention, Figure 3-Figure 7 As shown, the spray arm assembly 100 also includes: a clamping member 40, the clamping member 40 includes a clamping body 41 and an elastic arm 42 connected to the clamping body 41, the clamping body 41 is fixed to the spray arm 10, and the clamping body 41 and the elastic arm 42 are suitable for clamping on the two side surfaces of the side wall of the tableware 200 to be cleaned, so that the end of the spray arm 10 with the spray hole 11 extends into the tableware 200 to be cleaned.

[0055] During the process of cleaning the tableware 200, the side wall of the tableware 200 is gradually extended between the elastic arm 42 and the clamping body 41, and the side wall of the tableware 200 is squeezed against the trigger end 22 of the trigger member 20, so that the trigger member 20 is gradually rotated from the first position to the second position, and the blocking end 21 gradually opens the spray hole 11. When the tableware 200 is placed in place, the spray arm 10 is extended into the tableware 200 and the spray hole 11 is in an open state. At this time, water can be sprayed from the spray hole 11 to clean the tableware 200.

[0056] By providing the clamping member 40, on the one hand, the stability of the tableware 200 during the cleaning process can be improved, thereby improving the stability of the dishwasher during operation. On the other hand, the reliability of the tableware 200 acting on the trigger end 22 can be improved, thereby further improving the reliability of the dishwasher during operation.

[0057] In some embodiments of the present invention, Figure 3-Figure 7 As shown, the elastic arm 42 extends along the extension direction of the spray arm 10, one end of the elastic arm 42 is fixed to the clamping body 41, and the other end of the elastic arm 42 is formed with a clamping protrusion 421 protruding toward the clamping body 41, and the clamping protrusion 421 is suitable for abutting the outer surface of the tableware 200 to be cleaned.

[0058] By providing the clamping protrusion 421, the clamping protrusion 421 can more easily contact the outer surface of the tableware 200 when the side wall of the tableware 200 extends between the elastic element and the clamping body 41, thereby improving the reliability and stability of the clamping member 40 in clamping the tableware 200. During the product design process, parameters such as the shape, position, and size of the clamping protrusion 421 can be adjusted to meet various design requirements of the spray arm assembly 100.

[0059] In some embodiments of the present invention, Figure 3-Figure 7As shown, the elastic arm 42 extends along an arc that is away from the protrusion 421 of the spray arm 10 from one end of the elastic arm 42. As a result, after the clamping member 40 clamps the tableware 200, the elastic force of the end of the elastic arm 42 provided with the clamping protrusion 421 can be increased, thereby further improving the stability and reliability of the clamping member 40 in clamping the tableware 200.

[0060] In some embodiments of the present invention, Figure 3-Figure 7 As shown, a side surface of the clamping protrusion 421 facing the other end of the elastic arm 42 is formed as a guiding slope 422. In the direction from one end of the elastic arm 42 to the other end, the guiding slope 422 gradually extends away from the spray arm 10. In this way, during the process of loading the tableware 200, the guiding slope 422 can provide guidance for the tableware 200, making it easier to load the side wall of the tableware 200 between the elastic arm 42 and the clamping body 41, thereby reducing the difficulty of operation during use and further improving the user experience.

[0061] In some embodiments of the present invention, Figure 2-Figure 5 As shown, the clamping body 41 is cylindrical and extends along the extension direction of the spray arm 10. It is sleeved on the outside of the spray arm 10, and the trigger member 20 is provided on the clamping body 41. This, on the one hand, can increase the contact area between the clamping body 41 and the spray arm 10, thereby improving the reliability and stability of the connection between the clamping body 41 and the spray arm 10. On the other hand, the connection between the trigger member 20 and the clamping body 41, as well as the clamping space between the elastic arm 42 and the clamping body 41, are shorter than the spray hole 11, making it easier to arrange the trigger member 20. Moreover, after the side wall of the tableware 200 is clamped between the elastic arm 42 and the clamping body 41, the spray arm 10 is more easily inserted into the tableware 200.

[0062] Preferably, a rotating hole is formed in the middle of the clamping body 41 and the trigger member 20, and the spray arm assembly 100 also includes a rotating shaft 43, which passes through the rotating holes on the middle of the clamping body 41 and the trigger member 20 respectively, thereby realizing a rotatable connection between the clamping body 41 and the trigger member 20, and a torsion spring serving as a reset member 30 is provided at the fitting position of the rotating shaft 43 and the rotating hole.

[0063] In some embodiments of the present invention, Figure 2-Figure 4As shown, the elastic arm 42 is formed with an escape hole 423 that passes through the elastic arm 42 along the thickness direction. The escape hole 423 is used to avoid the trigger member 20. In the direction of the elastic arm 42 toward the spray arm 10, the elastic arm 42 and the trigger member 20 are arranged opposite each other. When the trigger member 20 rotates between the first position and the second position, the escape hole 423 provides an escape space for the trigger member 20, allowing the trigger member 20 to rotate normally. When the tableware 200 is clamped between the elastic arm 42 and the clamping body 41, the elastic arm 42 and the trigger member 20 can abut on both sides of the side wall of the tableware 200. In this way, the reliability and stability of the tableware 200 on the clamping member 40 can be further improved.
