Referring to fig. 1 to 11, the present invention provides a dishwasher (not shown) having a spray structure for cleaning dishes in the dishwasher. The spraying structure comprises a base 1, a plurality of nozzles 2 with vortex blades 26 mounted on the base 1, and a limiting structure 3 for limiting the nozzles 2 on the base 1, wherein in the embodiment, the base 1 is a spraying arm.

Referring to fig. 3 and 6, the spray arm 1 includes an in-line arm body 11, a cavity 12 disposed in the arm body 11, and a plurality of mounting openings 13 penetrating through the arm body 11 and communicating with the cavity 12, and the plurality of spray heads 2 are movably mounted in each mounting opening 13 in a one-to-one correspondence. In the present embodiment, the nozzle 2 is accommodated in the mounting opening 13, and the stopper structure 3 cooperates with the mounting opening 13 to vertically restrict the nozzle 2 so as to prevent the nozzle 2 from flying out of the mounting opening 13 during rotation.

The bottom of the spray arm 1 is provided with a water inlet end 15 which penetrates through the arm body 11 and is communicated with the cavity 12, and the top of the spray arm is provided with a plurality of mounting ports 13 and two water outlets 14. The two water outlets 14 are respectively arranged at two free ends of the spray arm 1, and the water outlet directions of the water outlets are opposite to each other. Therefore, when the water outlets 14 on the two sides simultaneously discharge water, the spray arm 1 can automatically rotate under the driving of the water flow pressure difference, so that multi-angle spraying is realized, and the spraying range is further expanded.

Referring to fig. 3 to 5, the limiting structure 3 includes a supporting rod 32 fixed on the arm 11 and a limiting portion 33 connected to the supporting rod 32 and located at the top of the supporting rod 32. The stopper 33 is provided with an inward recessed portion 31 that is formed to be recessed from bottom to top, and in the present embodiment, the top of the head 2 is located directly below the inward recessed portion 31.

Referring to fig. 3, 6 to 9, the nozzle 2 includes a hollow body 20, a protrusion 21 located at the top of the body 20, a plurality of nozzles 22 annularly disposed around the protrusion 21, an inner cavity 24 located in the body 20, and a vortex 25 and a central shaft 26 disposed in the inner cavity 24. The vortex blades 25 are spirally staggered on the central shaft 26.

The inner chamber 24 communicates with the nozzle 22. In this embodiment, external rivers enter into spray arm 1's cavity 12 through spray arm 1's the end 15 that intakes, and in the inner chamber 24 of later income shower nozzle 2, spout from nozzle 22 again, and the rivers that get into in the inner chamber 24 promote whirlpool leaf 25 through the pressure differential and rotate, and the rotatory in-process of whirlpool leaf 25 drives shower nozzle 2 at installing port 13 internal rotation to realize 2 multi-angle water sprays of shower nozzle, and then enlarge the spray range.

In this embodiment, rivers are followed delivery port 14 blowout, through two delivery port 14 that go out the opposite direction of water and set up to drive spray arm 1 rotation under the effect of rivers pressure differential, then, rivers are followed the nozzle 22 blowout of shower nozzle 2, drive whirlpool leaf 25 through rivers pressure differential and rotate, thereby drive shower nozzle 2 rotation, so, can realize the multiple rotation of spray arm 1 and shower nozzle 2, and then enlarged the spray regime of rivers, and realize that the multi-angle sprays, finally reach the effect that enlarges the spray regime.

In this embodiment, the top of each nozzle 2 is uniformly provided with three nozzles 22, and each nozzle 22 is cylindrically arranged, so that the water flow passing through the nozzles 22 is balanced along the radial direction. Of course, in other embodiments, there may be several nozzles 22, and the shape of the nozzles 22 may be designed to be a hollow cone, a polygonal column, a polygonal pyramid, or the like.

The convex portion 21 is provided at a middle position of the three nozzles 22, and is located right below the concave portion 31. The protrusion 21 is a cone-shaped structure, and the inner recess 31 is also a concave cone-shaped structure. With the arrangement, when the spray head 2 rotates, the inner concave part 31 can limit the spray head 2 in the radial direction, so that the spray head 2 is prevented from falling out under the action of water flow; meanwhile, the conical arrangement structure can also reduce the friction force between the convex portion 21 and the concave portion 31, so that the nozzle 2 can rotate freely and flexibly.

Referring to fig. 1 and 6, the outer periphery of the bottom of the nozzle 2 is provided with a sealing portion 23 protruding outward, and the sealing portion 23 abuts against the inner wall of the mounting opening 13. The sealing part 23 is used for preventing water in the spray arm 1 from leaking out of the peripheral edge of the spray head 2, and the sealing part 23 is not provided with any limiting structure so as to reduce the resistance when the spray head 2 rotates and enable the spray head to rotate more easily.

In other embodiments, the base 1 may be a dishwasher wall or a dishwasher base or the like.

In conclusion, the rotatable spray head 2 is arranged on the base 1 through the limiting structure 3, so that the spraying range of the base 1 is effectively expanded, the effect of no dead angle in washing is achieved, and the problem that the surface of tableware cannot be washed cleanly is solved.

The above embodiments are only used for illustrating the present invention and not for limiting the technical solutions described in the present invention, and the understanding of the present specification should be based on the technical personnel in the technical field, such as the directional descriptions of "front", "back", "left", "right", "upper", "lower", etc., and although the present specification has been described in detail with reference to the above embodiments, the ordinary skilled in the art should understand that the technical personnel in the technical field can still make modifications or equivalent substitutions on the present invention, and all technical solutions and modifications which do not depart from the spirit and scope of the present invention should be covered in the claims of the present invention.
