[0034] In the description of the present utility model, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0035] The following will be combined with Figures 1 to 6 to illustrate the embodiments of the present utility model.

[0036] A nozzle assembly of a dishwasher in this embodiment includes:

[0037] The spray arm 1 is provided with a water inlet channel inside, and both ends of the water passing channel 10 are communicated with the outside through the water inlet hole 11 and the water outlet hole 12;

[0038] The spray pipe 2 is arranged at the water outlet hole 12 and is communicated with the water inlet channel through the water outlet hole 12;

[0039] The nozzle head 3 is hermetically connected to the nozzle pipe 2 and rotates around the nozzle pipe 2. The nozzle head 3 includes a spray hole, and the axis of the spray hole is not parallel to the axis of the nozzle pipe 2, so that when water flows out of the spray hole, a rotational force is generated on the nozzle head 3.

[0040] This nozzle assembly is configured with a nozzle head 3 that can rotate when water flows out. When using this nozzle assembly for dishwashing, a rotating jet can be generated, which is beneficial to improving the cleaning effect.

[0041] In order to increase the rotational force generated by the water flow on the nozzle head 3, the nozzle head 3 further includes a jet pipe 31. The inner hole of the jet pipe 31 is communicated with the spray hole, and one end of the jet pipe 31 is hermetically connected to the nozzle head 3. The inner hole of the jet pipe 31 is coaxial with the spray hole, which is equivalent to the inner hole of the jet pipe 31 extending the length of the spray hole. On the one hand, it is beneficial to improve the directional stability of the jet when leaving the nozzle, and on the other hand, it can also increase the reaction force of the jet on the nozzle head 3 and improve the rotation speed of the nozzle head 3. In this embodiment, the jet pipe 31 and the nozzle head 3 are of an integral structure to simplify the structure of the jet pipe 31, reduce assembly, and save costs.

[0042] Furthermore, the number of the jet pipes 31 is two, and the two jet pipes 31 are arranged symmetrically with respect to the axis of the nozzle head 3 in rotation. By configuring two mutually rotationally symmetric jet pipes 31, the forces generated by the two jets on the nozzle head 3 can be superimposed, improving the rotation speed and rotational stability of the nozzle head 3.

[0043] The nozzle assembly further includes a connecting ring 4. A first clamping block 21 is provided on the side of the nozzle pipe 2 away from the spray arm 1. The connecting ring 4 is sleeved outside the nozzle pipe 2 and is rotatably connected to the nozzle pipe 2. A clamping groove is provided on the inner wall of the connecting ring 4. A connecting ring 4 is provided at one end of the nozzle head 3 away from the spray hole, and a second clamping block is provided on the outer wall of the connecting ring 4. The second clamping block extends into the clamping groove. The nozzle assembly is configured with a connecting ring 4. As a separate part, the connecting ring 4 is easy to ensure the manufacturing accuracy during manufacturing, which is beneficial to ensuring the rotational stability of the nozzle head 3.

[0044] The nozzle assembly further includes a bearing member 5, and the bearing member 5 is located between the connecting ring 4 and the first clamping block 21. By configuring the bearing member 5, the rotational resistance between the nozzle pipe 2 and the connecting ring 4 can be reduced, further ensuring the rotational stability of the nozzle head 3.

[0045] A flow guiding convex block 6 is provided on the inner wall of the nozzle head 3, and the flow guiding convex block 6 is located beside the spray hole. By providing the flow guiding convex block 6 on the inner wall of the nozzle head 3, when water flows through the flow guiding convex block 6, according to Bernoulli's principle, the flow guiding convex block 6 will generate a force that deflects the water towards the spray hole, increasing the speed of the water flowing into the flow guiding convex block 6.

[0046] The drainage bump 6 is arc-shaped. The drainage bump 6 includes a gentle side 61 and a steep side 62. The curvature change rate of the gentle side 61 is less than that of the steep side 62. The steep side 62 is closer to the spray hole than the gentle side 61. When the drainage bump 6 is arc-shaped and the side with a larger curvature change rate is closer to the spray hole, a better drainage effect is achieved.

[0047] The preferred embodiments of the present invention have been specifically described above, but the present disclosure is not limited to the above embodiments. Those skilled in the art can make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of the present disclosure.
