[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Example 1

[0031] like Figures 1 to 6 As shown, the cleaning machine of this preferred embodiment includes a housing 1 and a shelf assembly. The shelf assembly includes a frame 2, in which a first shelf 3 and a second shelf 4 are arranged sequentially in the left-right direction. The first shelf 3 is higher than the second shelf 4 and the two are connected. A spray arm 5 extending in the front-back direction is installed on the frame 2. The spray arm 5 is located directly below the first shelf 3 and next to the second shelf 4. The spray arm 5 has a spray hole 51 that communicates with its interior.

[0032] like Figure 3 , 4 As shown in Figure 5, one end of the spray arm 5 is open as the water inlet, and the other end is closed as the closed end. Mounting holes 21 are provided on both the front and rear side walls of the frame 2. The two ends of the spray arm 5 are respectively installed in the two mounting holes 21, with the mounting hole 21, where the water inlet is placed, penetrating the wall thickness of the corresponding side wall. A water supply pipe 6 is provided in the housing 1, and the water supply pipe 6 partially extends into the mounting hole 21 and connects to the spray arm 5.

[0033] In this embodiment, the frame 2, the first shelf 3, and the second shelf 4 are all plastic parts with a certain deformation allowance, which allows the spray arm 5 to be installed on them.

[0034] To prevent the spray arm 5 from rotating circumferentially relative to the mounting hole 21, at least one side wall of the frame 2 is provided with a groove 22 beside the mounting hole 21, and the spray arm 5 is provided with a block 52 that can be fitted into the groove 22; alternatively, at least one side wall of the frame 2 is provided with a block 52 beside the mounting hole 21, and the spray arm 5 is provided with a groove 22 into which the block 52 can be fitted. The cooperation between the block 52 and the groove 22 serves to limit the displacement of the spray arm 5 in the circumferential direction.

[0035] There are multiple spray holes 51 facing the first shelf 3 and / or the second shelf 4. At least two of the spray holes 51 are arranged in a row along the axial direction of the spray arm 5 to form a spray hole group. In this embodiment, there is one spray hole group. Of course, there may also be at least two spray hole groups that are spaced apart along the circumference of the spray arm 5.

[0036] like Figure 2 As shown, an upper spray arm 7 is also provided above the frame 2. The upper spray arm 7 is also connected to the water supply pipe 6. The upper spray arm 7 can adopt the existing spray arm structure. The upper spray arm 7 and the spray arm 5 work together, one above the other, to achieve a good cleaning effect on the tableware on the shelf.

[0037] Example 2

[0038] like Figures 7 to 10 As shown, the difference between this embodiment and embodiment 1 is that the spray arm 5 in this embodiment can rotate around its axis.

[0039] The closed end of the spray arm 5 is equipped with a knob 8 that is easy for the user to hold and rotate. The knob 8 is fixed relative to the spray arm 5 in the circumferential direction. By rotating the knob 8, the spray arm 5 can be rotated to adjust the spray angle of the spray nozzle 51 to adapt to the cleaning of different tableware.

[0040] In this embodiment, the closed end of the spray arm 5 is provided with a socket 53, and the knob 8 is provided with a plug 81 that can be inserted into the socket 53. The plug 81 and the socket 53 are connected by a connecting structure. The connecting structure includes a fastener 54 and a fastener 82. The fastener 54 is provided in the socket 53, and the fastener 82 is provided on the plug 81. The fastener 54 is provided with a fastening groove 541 for the fastener to be fastened.

[0041] In this embodiment, the mounting hole 21, in which the closed end of the spray arm 5 is placed, also penetrates the wall thickness of the corresponding side wall. The knob 8 is located on the outside of the frame 2. In this embodiment, the knob 8 is located on the front side of the frame 2 for easy user operation. At least two protrusions 83 are evenly spaced along the circumference of the spray arm 5 on the knob 8. At least two slots 23 are evenly spaced along the circumference of the mounting hole 21 on the side wall of the frame 2. The slots 23 allow the protrusions 83 to be detachably placed inside them. Preferably, the number of slots 23 is greater than the number of protrusions 83. When the protrusions 83 are engaged in the slots 23, the knob 8 will not rotate without external force because the knob 8 and the spray arm 5 are fixed relative to each other in the circumference, so the spray arm 5 will not rotate.

[0042] Example 3

[0043] like Figure 11 As shown, the difference between this embodiment and Embodiment 1 is that a flexible element 9 is embedded in the nozzle 51, and the flexible element 9 is provided with a nozzle 91 that can open under the impact of water flow and close in a natural state. In this way, the opening size of the nozzle 91 is different under different cleaning sequences and different hydraulic heads, achieving a more refined cleaning effect.

[0044] In this embodiment, the nozzle 91 is H-shaped. Of course, the nozzle 91 can also be other shapes. The flexible part 9 can be made of materials such as silicone or rubber.

[0045] When there is no water flow, nozzle 91 is in a closed state. Under different timing and hydraulic head, the opening of nozzle 91 is different. The greater the head, the larger the opening and the more intense the water flow; when the head is smaller, the opening is smaller and the water flow is gentler, protecting the tableware from being scratched.

[0046] Example 4

[0047] This embodiment is a combination of Embodiment 1 and Embodiment 3.

[0048] Example 5

[0049] This embodiment is a combination of Embodiment 2 and Embodiment 3.
