[0032] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0033] In response to the problem that the spray device in the prior art fails to achieve the expected cleaning effect during actual use, the inventors have discovered through research and testing that when the above-mentioned spray device is in cleaning operation, the cross-section of the rotating water flow sprayed out is fan-shaped and reflective, and the overall shape is conical. The pressure of this shape of water flow will be reduced at the end, that is, the pressure applied to the tableware will not be very large (the surface area increases and the pressure decreases), which results in the sprayed rotating water flow failing to achieve the expected cleaning effect.

[0034] Based on this, the following embodiments of the present application, including a rotating spray hole assembly, a spray arm structure and a dishwasher, are designed and proposed to solve the above-mentioned technical problems.

[0035] As shown in FIG1 , in one embodiment, a rotating spray hole assembly 100 is provided, comprising a mounting body 110 and a rotating blade 120. The mounting body 110 is provided with a water inlet 111 and a spray hole 112 which are interconnected. The rotating blade 120 is installed in the water inlet 111 and can rotate under the action of the water flow to drive the water flow flowing in from the water inlet 111 to form a rotating water column. The inner side wall of the spray hole 112 is provided with rifling 113, and the rifling 113 is used to guide the rotating water column to keep rotating and to gather the rotating water column.

[0036] The rotating spray hole assembly 100 in the above embodiment, when in use, delivers water to the water inlet 111, and the water first passes through the rotating blades 120, and the rotating blades 120 rotate accordingly under the action of the water to drive the water to form a rotating water column. The rotating water column enters the spray hole 112, and the rifling 113 in the spray hole 112 can guide the rotating water column to maintain the rotating flow, and can also make the rotating water column gather, inhibit the dispersion of the rotating water column, so that the stability of the rotating water column is increased. After the rotating water column is ejected from the spray hole 112, the cross-sectional area of ​​the rotating water column along the axis direction perpendicular to the spray hole 112 remains stable, and the rotating water column can maintain a large kinetic energy and pressure, thereby improving the cleaning effect of the rotating spray hole assembly 100.

[0037] Specifically in this embodiment, the cross section of the rotating water column ejected from the spray hole 112 is square-shaped and the whole is cylindrical.

[0038] The number of rifling 113 can be flexibly adjusted according to actual use needs. Specifically in this embodiment, the number of rifling 113 can be set to six. The rifling 113 can be set as a rib structure.

[0039] Specifically in this embodiment, the water inlet 111 and the spray hole 112 are coaxially arranged and both are arranged in a cylindrical shape. The rotation axis of the rotating blade 120 and the central axis of the water inlet 111 are located on the same straight line.

[0040] As shown in FIG. 1 and FIG. 2 , optionally, the inner side wall of the spray hole 112 is provided with at least one rifling 113, each rifling 113 extends in the spiral direction and is arranged at intervals along the circumference of the spray hole 112. In this way, by increasing the number of rifling 113, the rotation stability and gathering stability of the rotating water column are increased, thereby improving the cleaning effect of the rotating spray hole assembly 100.

[0041] The rotating blade 120 can be set to any structure in the prior art that can drive water flow to form a rotating water column. Specifically in this embodiment, the direction of the spiral line is the same as the rotation direction of the rotating water column. The direction in which the rotating blade 120 guides the water flow is the same as the extension direction of the rifling 113. Two adjacent riflings 113 cooperate with the inner side wall of the nozzle opening 112 located between the two riflings 113 to form a guide groove, which is used to guide the rotating water column to maintain a rotating flow and to gather the rotating water column.

[0042] As shown in Fig. 1 and Fig. 2, in one embodiment, the rotating blade 120 includes a mounting cylinder 121 and a blade body 122 mounted in the mounting cylinder 121, and the mounting cylinder 121 is rotatably mounted on the water inlet 111. In this way, the convenience of assembling the rotating spray hole assembly 100 is improved.

[0043] Specifically in this embodiment, the number of blade bodies 122 can be flexibly adjusted according to actual use needs. The number of blade bodies 122 is at least two, and each blade body 122 is installed in the installation cylinder 121 around the axis of the installation cylinder 121. The installation cylinder 121 and each blade body 122 are integrally formed.

[0044] As shown in Fig. 2 and Fig. 3, optionally, the inner diameter of the water inlet 111 is larger than the inner diameter of the spray hole 112, and the mounting cylinder 121 is configured to be limitedly matched with the inner end surface of the water inlet 111 near the spray hole 112 when the mounting cylinder 121 is rotatably mounted on the water inlet 111. In this way, the inner end surface of the water inlet 111 near the spray hole 112 can play a positioning role, ensuring that the rotating blade 120 can be quickly and accurately installed on the water inlet 111, thereby improving the convenience of assembling the rotating spray hole assembly 100.

[0045] As shown in Fig. 2 and Fig. 3, optionally, the rotary spray hole assembly 100 further includes a rolling member 130, which is installed in the water inlet 111 and is used to rotatably connect the mounting cylinder 121 to the inner side wall of the water inlet 111. In this way, the rolling member 130 can reduce the friction between the rotating blade 120 and the mounting body 110, so that the rotating blade 120 can rotate smoothly in the water inlet 111, thereby improving the reliability of the rotary spray hole assembly 100.

[0046] As shown in Figures 2 and 3, specifically in this embodiment, the outer wall of the mounting cylinder 121 is provided with a first annular groove 123, and the inner wall of the water inlet 111 is provided with a second annular groove 114 corresponding to the first annular groove 123.

The rolling element 130 is configured as a ball, and there are multiple balls. All of the balls are installed in the rolling space so that the mounting cylinder 121 is rotatably connected to the inner wall of the water inlet 111.

[0047] In other embodiments, the rolling element 130 may also be configured as a rolling bearing or other rolling structures.

[0048] As shown in FIG. 2 and FIG. 3 , in one embodiment, the mounting body 110 includes a first housing 115 and a second housing 116, the first housing 115 is provided with a first groove 1151 and a second groove 1152 that are interconnected, the second housing 116 is provided with a third groove 1161 and a fourth groove 1162 that are interconnected, and the first housing 115 and the second housing 116 are detachably connected, so that the inner wall of the first groove 1151 and the inner wall of the third groove 1161 are surrounded to form a water inlet 111, and the inner wall of the second groove 1152 and the inner wall of the fourth groove 1162 are surrounded to form a spray hole 112. In this way, the mounting body 110 is a detachable structure, which is convenient for the processing of the rifling 113 and the assembly of the rotating blade 120.

[0049] The first housing 115 can be detachably connected to the second housing 116 by snapping, plugging, clamping or other methods. Specifically in this embodiment, the shape and size of the first housing 115 are the same as those of the second housing 116.

[0050] As shown in Figures 2 and 3, optionally, a first connecting column 1153 is provided on the side of the first shell 115 close to the second shell 116, and a first connecting hole 1163 corresponding to the first connecting column 1153 is provided on the side of the second shell 116 close to the first shell 115, and the first connecting hole 1163 is plugged into and fits with the first connecting column 1153.

[0051] As shown in Figures 2 and 3, optionally, a second connecting hole 1154 is provided on the side of the first shell 115 close to the second shell 116, and a second connecting column 1164 corresponding to the second connecting hole 1154 is provided on the side of the second shell 116 close to the first shell 115, and the second connecting column 1164 is plugged into and fits with the second connecting hole 1154.

[0052] Specifically in this embodiment, there are two first connecting columns 1153, first connecting holes 1163, second connecting columns 1164 and second connecting holes 1154. The two first connecting columns 1153 are arranged at two diagonally opposite corners of the side of the first shell 115 close to the second shell 116. The two second connecting columns 1164 are arranged at the other two diagonally opposite corners of the side of the first shell 115 close to the second shell 116. The two first connecting holes 1163 are arranged at two diagonally opposite corners of the side of the second shell 116 close to the first shell 115. The two second connecting holes 1154 are arranged at the other two diagonally opposite corners of the side of the second shell 116 close to the first shell 115. In this way, the connection strength between the first shell 115 and the second shell 116 is ensured, and the reliability of the rotating spray hole assembly 100 is improved.

[0053] As shown in Fig. 4 and Fig. 5, in one embodiment, a spray arm structure 10 is provided, comprising a spray arm body 200 and a rotating spray hole assembly 100 in any of the above embodiments. The spray arm body 200 is provided with a receiving cavity 201 and a mounting hole 202 communicating with the receiving cavity 201, and the rotating spray hole assembly 100 is mounted in the mounting hole 202 so that the water inlet 111 is communicated with the receiving cavity 201.

[0054] When the spray arm structure 10 in the above embodiment is used, water is continuously injected into the accommodating chamber 201, so that the water in the accommodating chamber 201 flows into the water inlet 111, and the water flow first passes through the rotating blades 120. The rotating blades 120 rotate accordingly under the action of the water flow to drive the water flow to form a rotating water column. The rotating water column enters the spray hole 112, and the rifling 113 in the spray hole 112 can guide the rotating water column to maintain the rotating flow, and can also make the rotating water column gather, inhibit the dispersion of the rotating water column, so that the stability of the rotating water column is increased. After the rotating water column is ejected from the spray hole 112, the cross-sectional area of ​​the rotating water column along the axis direction perpendicular to the spray hole 112 remains stable, and the rotating water column can maintain a large kinetic energy and pressure, thereby improving the cleaning effect of the spray arm structure 10.
