In the prior art, the spray nozzle in the dishwasher is usually fixedly arranged on the spray arm, and the spray nozzle generally sprays water columns in different directions by arranging the open holes in different directions on the spray arm. Because the water pressure that supplies the spray arm is relatively fixed, has sufficient water pressure when guaranteeing the spray arm to wash, the trompil quantity on the spray arm is limited, from this, can't realize the omnidirectional washing that sprays of nozzle, and it is narrow and small to have the washing region, and cleaning performance is poor defect.

In view of the above, the present invention provides a nozzle assembly 100, and referring to fig. 1 and 2, the nozzle assembly 100 includes: a support base 120 provided with a first water inlet 121; the rotating piece 110 is rotatably arranged on the supporting seat 120, the rotating piece 110 is arranged in a hollow manner to form a hollow cavity 111, the rotating piece 110 is provided with a rotating axis L, at least one fin 113 distributed along the circumferential direction of the rotating axis L is arranged on the outer circumferential surface of the rotating piece 110, a plurality of jet ports 112 used for jetting water flow are further arranged on the rotating piece 110, and the jet ports 112 are communicated with the hollow cavity 111; a water flow channel 130 communicated with the first water inlet 121 is formed between the supporting base 120 and the rotating member 110, and at least one fin 113 is located in the water flow channel 130 to drive the rotating member 110 to rotate in response to the action of water flow in the water flow channel 130.

Through the manner, the rotating member 110 continuously rotates on the supporting seat 120 by utilizing the water flow impact fins 113 in the water flow channel 130, so that the cleaning radiation area of the jet orifice 112 is effectively enlarged, the dead-corner-free cleaning can be realized, and the cleaning effect is good.

In the present invention, referring to fig. 3 and 4, a pair of rotating shafts 114 are further disposed on the outer peripheral surface of the rotating member 110 along the direction of the rotation axis L, and the rotating member 110 is rotatably disposed on the supporting base 120 through the rotating shafts 114. The supporting seat 120 is provided with a rotating shaft seat 123 for installing the rotating shaft 114, the rotating shaft seat 123 is provided with a rotating shaft hole 1231 matched with the rotating shaft 114, an opening 1232 is formed in the circumferential direction of the rotating shaft hole 1231, and the rotating shaft 114 can be conveniently clamped into the rotating shaft hole 1231 by arranging the opening 1232. The profile of the rotating member 110 is preferably spherical to facilitate rotation of the rotating member 110 itself. The support base 120 is used to support the rotary member 110, and the shape of the support base 120 is determined according to the shape of the rotary member 110. Preferably, the supporting base 120 is bowl-shaped to form a receiving cavity 122, and the rotating element 110 is at least partially received in the receiving cavity 122. Of course, in other embodiments, the rotating member 110 may have other shapes as well, including but not limited to a spherical shape.

For convenience of description, the rotation member 110 is defined as a sphere, and after the rotation member 110 is mounted to the support base 120, the fins 113 provided on the lower spherical surface of the rotation member 110 are located in the water flow channel 130, and the fins 113 provided on the upper spherical surface of the rotation member 110 are located outside the water flow channel 130. When water flows are introduced into the water flow channel 130, the fins 113 on the lower spherical surface can drive the rotating member 110 to rotate around the rotation axis L under the impact of the water flow in the water flow channel 130. In the rotation process of the rotating member 110, the position of the fin 113 relative to the support base 120 is constantly changed, specifically, the fin 113 originally located on the lower spherical surface is rotated away from the water flow channel 130 after the rotating member 110 rotates, and the fin 113 originally located on the upper spherical surface is rotated into the water flow channel 130, so that the circulation is repeated, and the fin 113 is ensured to always drive the rotating member 110 to rotate in response to the action of the water flow in the water flow channel 130. The water flow channel 130 is provided in various forms, and in consideration of the rotation characteristic and the implementation convenience of the rotating member 110, in the present invention, a groove 1221 with two open ends is formed on the cavity wall of the accommodating cavity 122, the groove 1221 and the outer peripheral surface of the rotating member 110 jointly enclose the water flow channel 130, and the groove 1221 and the fin 113 are located on the same circumference with the rotation axis L as the center, so as to ensure that the fin 113 can enter the groove 1221 when rotating around the rotation axis L, therefore, the water flow channel 130 is provided with a simpler structure and is more convenient to use. In order to ensure that the groove body 1221 and the outer peripheral surface of the rotating member 110 have a good fit, and avoid that a gap exists between the groove body 1221 and the outer peripheral surface of the rotating member 110 to affect the water pressure in the water flow channel 130, in the present invention, the cavity wall of the accommodating cavity 122 is preferably a spherical surface matched with the outer peripheral surface of the rotating member 110, and the groove body 1221 is an arc groove, so that the fit between the groove body 1221 and the outer peripheral surface of the rotating member 110 can be better improved.
