DETAILED DESCRIPTION

[0048] Embodiments of the present invention are described in detail below, 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0049] The following describes a spray arm assembly 2 of a dishwasher according to an embodiment of the present invention with reference to the accompanying drawings.

[0050] like Figure 1-Figure 16 As shown, the spray arm assembly 2 of the dishwasher according to the embodiment of the present invention includes a water distribution pipe 300 and a rotating part 400 .

[0051] The water distribution pipe 300 is connected to the dish basket 1 of the dishwasher. The rotating part 400 has a water passage 401 and a spray hole 402. The rotating part 400 is rotatably arranged on the water distribution pipe 300 between an unfolded state and a folded state. In the unfolded state, the water passage 401 is in fluid communication with the water distribution pipe 300, and in the folded state, the water passage 401 is disconnected from the water distribution pipe 300.

[0052] For example, the water distribution pipe 300 is fixedly connected to the bowl basket 1 of the dishwasher. The rotating part 400 is connected to the water distribution pipe 300 and can rotate relative to the water distribution pipe 300 between the unfolded state and the folded state. In the unfolded state, the water passage 401 is in fluid communication with the water distribution pipe 300, and the water passage 401 and the water distribution pipe 300 extend in the same direction. In the folded state, the water passage 401 is disconnected from the water distribution pipe 300, and a certain angle is formed between the water passage 401 and the water distribution pipe 300, and the angle is less than 90 degrees.

[0053] According to the spray arm assembly 2 of the dishwasher of the embodiment of the present invention, by providing the water distribution pipe 300 and the rotating part 400, the rotating part 400 can be rotated relative to the water distribution pipe 300, so that the rotating part 400 can be switched between the unfolded state and the folded state. When the spray arm assembly 2 is working, the rotating part 400 can be in the unfolded state, so as to achieve smooth fluid communication between the water passage 401 and the water distribution pipe 300, so that the water flows through the water distribution pipe 300 and then flows through the water passage 401 and then sprays out from the spray hole 402, so as to spray and wash the dishes in the dishwasher. When the spray arm assembly 2 is not needed, the rotating part 400 can be rotated to the folded state, at which time there is a certain angle between the rotating part 400 and the water distribution pipe 300, so as to facilitate the storage of the spray arm assembly 2 and reduce the space size occupied by the spray arm assembly 2. Thus, the outer dimensions of the spray arm assembly 2 can be flexibly changed, which not only makes it convenient to use the spray arm assembly 2 to spray wash the dishes, but also reduces the outer dimensions of the spray arm assembly 2 when the spray arm assembly 2 is not needed, thereby reducing the space required for the spray arm assembly 2, facilitating the flexible use of the internal space of the dishwasher, and making the use of the internal space of the dishwasher more reasonable and effective.

[0054] Furthermore, the water passage 401 is in fluid communication with the water distribution pipe 300 in the unfolded state, and is disconnected from the water distribution pipe 300 in the folded state. In this way, the water flow can be controlled by the rotation of the rotating part 400, and the water connection of the spray arm assembly 2 can be timely and reliably cut off when the spray arm assembly 2 is not in use, thereby improving the working reliability of the spray arm assembly 2.

[0055] Therefore, the spray arm assembly 2 of the dishwasher according to the embodiment of the present invention has the advantages of variable outer dimensions and the ability to control the on and off of the water channel.

[0056] The spray arm assembly 2 of a dishwasher according to a specific embodiment of the present invention will be described below with reference to the accompanying drawings.

[0057] In some specific embodiments of the present invention, Figure 1-Figure 16 As shown, the spray arm assembly 2 of the dishwasher according to the embodiment of the present invention includes a water distribution pipe 300 and a rotating part 400 .

[0058] Specifically, Fig.12 As shown, the water distribution pipe 300 has a water outlet 301, and the rotating part 400 has a water inlet 403 connected to the water passage 401. In the unfolded state, the water outlet 301 is connected to the water inlet 403, and in the folded state, the water outlet 301 is disconnected from the water inlet 403. In this way, the water inlet 403 and the water outlet 301 can be used to connect or disconnect the water path, so as to facilitate the control of the water path of the spray arm assembly 2.

[0059] More specifically, Fig.12As shown, the water distribution pipe 300 includes a pipe body 310, and a water outlet 301 is provided on the pipe body 310. Fig.13 As shown, the rotating part 400 includes a first connecting part 410, the first connecting part 410 is rotatably connected to the pipe body 310, and the water inlet 403 is provided at the first connecting part 410 and rotates synchronously with the first connecting part 410. This not only facilitates the smooth rotation of the rotating part 400, but also can simultaneously control the connection or disconnection of the water inlet 403 and the water outlet 301 during the rotation of the rotating part 400, so as to control the water connection of the spray arm assembly 2.

[0060] Further, the outer peripheral wall of the pipe body 310 is formed as a first cylindrical surface, the water outlet 301 is located on the first cylindrical surface, the inner peripheral wall of the first connecting part 410 is formed as a second cylindrical surface, the water inlet 403 is located on the second cylindrical surface, the first cylindrical surface and the second cylindrical surface are rotatably matched, the water outlet 301 and the water inlet 403 are arranged opposite to each other in the unfolded state, and the water outlet 301 and the water inlet 403 are arranged staggered in the folded state. In this way, not only can the reliable rotation of the rotating part 400 relative to the water distribution pipe 300 be achieved, but also in the folded state, the first cylindrical surface can be used to block the water inlet 403, and the second cylindrical surface can be used to block the water outlet 301, so as to cut off the water connection between the water distribution pipe 300 and the water passage 401.

[0061] Alternatively, if Figure 12-13 As shown, the bottom wall of the pipe body 310 has a first connection hole 311, the bottom wall of the first connection part 410 has a second connection hole 411, and the pipe body 310 and the first connection part 410 are connected through a connection piece fitted in the first connection hole 311 and the second connection hole 411. In this way, the water distribution pipe 300 and the rotating part 400 can be reliably connected, thereby improving the structural reliability of the spray arm assembly 2.

[0062] Further, the center line of the connecting member may be the rotation axis of the rotating part 400 .

[0063] In some embodiments, the rotation axis of the first connection part 410 is perpendicular to the extension direction of the rotating part 400. In this way, the setting direction of the rotating part 400 can be changed by rotating the first connection part 410, so as to facilitate the storage of the spray arm assembly 2.

[0064] Specifically, Fig.12As shown, the water distribution pipe 300 also includes a pipe joint 320, which is arranged on the pipe body 310, and the peripheral wall of the first connecting portion 410 has a limiting notch 412. In the unfolded state, one side edge of the limiting notch 412 cooperates with the pipe joint 320 for limiting, and in the folded state, the other side edge of the limiting notch 412 cooperates with the pipe joint 320 for limiting. It should be understood here that the pipe joint 320 can be connected with an external water source, and the water distribution pipe 300 can be connected with the external water source through the pipe joint 320. In this way, not only can the water distribution pipe 300 be connected with the external water source, but also the limiting notch 412 can be used to limit the rotation of the rotating portion 400, so that the rotating portion 400 can be reliably switched between the unfolded state and the folded state.

[0065] The rotating part 400 is described in detail below according to an embodiment of the present invention.

[0066] Specifically, Fig. 9 and Fig.11 As shown, the rotating part 400 includes a first water pipe 420 and a second water pipe 430, and the first water pipe 420 is rotatably connected to the water distribution pipe 300. The second water pipe 430 is rotatably connected to the first water pipe 420, and the water passage 401 includes a first channel 404 and a second channel 405. The first channel 404 is formed in the first water pipe 420, and the second channel 405 is formed in the second water pipe 430. In the unfolded state, the first water pipe 420 and the second water pipe 430 have the same extension direction, and in the folded state, there is a first angle between the first water pipe 420 and the second water pipe 430. In this way, the rotating part 400 can be folded twice, which further facilitates reducing the external dimensions of the spray arm assembly 2.

[0067] Specifically, in the folded state, a first angle between the first water pipe 420 and the second water pipe 430 is less than 90 degrees.

[0068] More specifically, Fig.13 As shown, the first water pipe 420 has a first rotating portion 421, and the first rotating portion 421 has a first water passage cavity 422 communicating with the first channel 404. Fig.14 As shown, the second water pipe 430 has a second rotating portion 431, the second rotating portion 431 has a second water passage cavity communicated with the second channel 405, the first rotating portion 421 and the second rotating portion 431 are rotatably matched, and the first water passage cavity 422 is in fluid communication with the second water passage cavity. In this way, while the first water pipe 420 and the second water pipe 430 are relatively rotated, the first water pipe 420 and the second water pipe 430 can be in fluid communication.

[0069] Alternatively, if Fig. 9 and Fig.11As shown, the rotating part 400 further includes a spray arm 440, a spray hole 402 is formed in the spray arm 440, the spray arm 440 is rotatably connected to the second water pipe 430, and the spray arm 440 has a third water passage chamber 441 communicated with the spray hole 402, and the third water passage chamber 441 is fluidically communicated with the second channel 405. In this way, not only can the spray arm 440 be rotated relative to the second water pipe 430 to increase the spray range of the spray arm 440, but also the spray arm 440 is easily communicated with the second water pipe 430.

[0070] Specifically, Fig.14 As shown, the second water pipe 430 is also provided with a third rotating part 432, the second rotating part 431 and the third rotating part 432 are respectively arranged at two ends of the second water pipe 430 in the length direction, the middle part of the spray arm 440 is rotatably connected to the second water pipe 430 through the third rotating part 432, and the spray holes 402 are multiple and are arranged at intervals along the length direction of the spray arm 440.

[0071] Furthermore, the rotation axes of the first water pipe 420 and the second water pipe 430 are arranged parallel to the rotation axis of the spray arm 440. This facilitates storage of the spray arm assembly 2 and further reduces the space required for arranging the first water pipe 420, the second water pipe 430 and the spray arm 440.

[0072] According to some specific embodiments of the present invention, the water distribution pipe 300 is composed of two mutually perpendicular cylindrical tubular structure pipe bodies 310 and a pipe joint 320. The pipe joint 320 is arranged at the source water inlet and is used to connect an external water source such as a dishwasher water distributor. A water outlet 301 is arranged on the first cylindrical surface of the pipe body 310. The upper end of the pipe body 310 is open and the lower end has a pin hole. The upper end of the water distribution pipe 300 has a buckle structure, which can be fixed on the bowl basket 1 of the dishwasher.

[0073] The first water pipe 420 is a tubular part, with a first connecting part 410 in a semi-cylindrical shape at the rear end, and a water inlet 403 is provided on the second cylindrical surface of the first connecting part 410. A pin hole is provided at the upper end of the first connecting part 410, and a first rotating part 421 formed as a cylindrical rotating shaft is provided at the front end of the first water pipe 420. The second water pipe 430 is a tubular part, with a second rotating part 431 formed as a rotating shaft at the rear end, and a mounting groove for the spray arm 440 is provided at the front end.

[0074] The first connecting part 410 is formed as a semi-cylindrical structure with a limiting notch 412, and is installed on the pipe body 310 of the water distribution pipe 300. The pin passes through the pin hole to fix the water distribution pipe 300 and the first water pipe 420 together, and the first water pipe 420 can rotate around the first cylindrical surface and the second cylindrical surface. The pin passes through the pin hole to assemble the first rotating part 421 of the first water pipe 420 and the second rotating part 431 on the second water pipe 430 together. The second water pipe 430 can rotate with the pin as the axis. The fastener 450 is formed as a snap ring, which is assembled in the installation groove of the spray arm 440 at the front end of the second water pipe 430. The spray arm assembly 2 is assembled together with the snap ring through the snap structure. The spray arm assembly 2 is assembled on the bowl basket 1 through the snap, the pin and the pin hole.

[0075] When the bowl basket 1 is in the open state, the water distribution pipe 300, the first water pipe 420, and the second water pipe 430 are in a straight line, the water outlet 301 on the water distribution pipe 300 and the water inlet 403 on the first water pipe 420 overlap, and the water flows through the water distribution pipe 300, through the water outlet 301 and the water inlet 403 on the first water pipe 420, into the first water pipe 420, and then into the spray arm 440 through the second water pipe 430, and the spray arm 440 works normally. When the bowl basket 1 is in the storage state, the bowl basket 1 drives the second water pipe 430 and the first water pipe 420 to rotate, the first water pipe 420 and the water distribution pipe 300 form a certain angle, the water outlet 301 on the water distribution pipe 300 and the water inlet 403 on the first water pipe 420 are not in the overlapping position, the water flow is blocked by the first cylindrical surface on the first water pipe 420, and the spray arm 440 does not work.

[0076] According to a specific embodiment of the present invention, the spray arm assembly 2 includes a water distribution pipe 300 and a rotating part 400. The water distribution pipe 300 is connected to the dish basket 1 of the dishwasher. The rotating part 400 has a water passage 401 and a spray hole 402.
