Therefore, the above terms should not be construed as a limitation of this utility model.

[0042] Please refer to Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 9 and Figure 15 As shown, this application provides a water cup structure for a dishwasher, including a water cup body 1, a water distribution assembly, and a drive assembly. The water cup body 1 is provided with a water collection chamber 2 and a water distribution connector. The water distribution connector includes a connection port and a water distribution channel. The water distribution connector is located on the side of the water collection chamber 2, the connection port is located on the lower side of the water distribution connector, and the water distribution channel is located on the upper side of the water distribution connector. The water distribution assembly includes a valve seat 5 and a water distribution valve plate 10. The valve seat 5 is detachably connected to the water cup body 1. The valve seat 5 is provided with a water distribution chamber 6 communicating with the water distribution channel. The opening of the water distribution chamber 6 is connected to the connection port. The water distribution valve plate 10 is located at the opening of the water distribution chamber 6. The drive assembly includes a mounting base 7 and a drive component 13 for driving the water distribution valve plate 10 to rotate. The drive component 13 is located on the mounting base 7, and the mounting base 7 is detachably connected to the valve seat 5. A positioning assembly is provided between the valve seat 5 and the water cup body 1. The positioning assembly is used to align the opening of the water distribution chamber 6 with the connection port. This application adopts a detachable connection between the water cup body 1, valve seat 5, and mounting base 7, allowing for easy disassembly and reassembly of each component when maintenance or replacement is required. A positioning component is provided between the valve seat 5 and the water cup body 1 to ensure automatic alignment of the opening of the water distribution chamber 6 with the connection port, further facilitating the connection between the valve seat 5 and the water cup body 1. Furthermore, the positioning component can enhance the stability of the connection between the valve seat 5 and the water cup body 1 to a certain extent, preventing loosening or misalignment of components due to vibration or water flow impact during dishwasher operation, thereby extending the service life of the water cup structure.

[0043] like Figures 3-7 As shown, specifically, the water cup body 1 has several hollow, downwardly extending first pins 17. The inner circumferential wall of the first pin 17 is threaded, and the opening of the first pin 17 faces the valve seat 5. The valve seat 5 has several first mounting holes 18 corresponding to the first pins 17. One end of the bolt passes through the first mounting hole 18 and is threaded to the first pin. The bolt is screwed into the first pin 17 from the valve seat 5, forming a tight mechanical lock, which has stronger resistance to vibration and loosening.

[0044] The positioning component includes a first positioning component, which includes a first slot 19 disposed on the water cup body 1 and a first block 20 disposed on the valve seat 5. The first slot 19 and the first block 20 cooperate to align the opening of the water distribution chamber 6 with the connection port. The first block 20 is located in the first slot 19 to achieve positioning. It can be understood that after the first block 20 is located in the first slot 19, it not only achieves the positioning function, but also plays a connecting role, strengthening the connection between the water cup body 1 and the valve seat 5.

[0045] Furthermore, the positioning assembly also includes a second positioning assembly, which includes a positioning protrusion 21 disposed on the water cup body 1 and a positioning hole 22 disposed on the valve seat 5. The positioning protrusion 21 and the positioning hole 22 cooperate to align the opening of the water distribution chamber 6 with the connection port. The positioning protrusion 21 is inserted into the positioning hole 22 to achieve positioning.

[0046] It is understandable that the positioning component of this application not only serves a positioning function, but also enhances the structural stability between the valve seat 5 and the water cup body 1 to a certain extent. The advantage of using the first positioning component and the second positioning component for dual positioning is that the first slot 19 and the first block 20 cooperate to provide pre-fixation, so that the operator can maintain the position of the valve seat 5 without applying additional force. Then, the positioning protrusion 21 and the positioning hole 22 cooperate to fine-tune and achieve final positioning, effectively preventing reverse assembly or misaligned assembly.

[0047] like Figure 1 As shown, there are two water distribution channels: a first channel 3 and a second channel 4. The first channel 3 is used to connect to the inner water pipe to supply water to the middle and top spray arms, while the second channel 4 is used to connect to the bottom spray arm to supply water to it. The connection between the first channel 3 and / or the second channel 4 and the water distribution chamber 6 is controlled by adjusting the water distribution valve plate 10.

[0048] Please refer to Figure 1 , Figure 5 and Figure 6As shown, the water cup body 1 is provided with an outlet 11, the water collecting chamber 2 is connected to the outlet 11, the valve seat 5 is provided with an inlet 12, and the water distribution chamber 6 is connected to the inlet 12. A connecting pipe is provided between the inlet 12 and the outlet 11. Water from the collecting chamber 2 enters the water distribution chamber 6 through the outlet 11, the connecting pipe, and the inlet 12. It is understood that the connecting pipe is also connected to a circulation pump, and water from the collecting chamber 2 enters the water distribution chamber 6 under the action of the circulation pump. Specifically, the bottom of the water distribution chamber 6 is a sloping structure 14, and the inlet 12 is located on the side of the sloping structure 14 with a lower height. The lower edge of the inlet 12 connects smoothly to the sloping structure 14 through an arc-shaped surface. This design reduces the local water flow velocity and pressure when the circulating water enters the water distribution chamber 6, not only reducing water pressure loss but also making the water flow more stable. Stable water flow reduces noise and vibration caused by water flow impact when the circulating water enters the water distribution chamber 6.

[0049] Please refer to Figure 7 , Figure 8 and Figure 9 As shown, in one embodiment of this disclosure, the mounting base 7 includes a detachably connected base 9 and a connecting base 8. The driving member 13 is disposed on the connecting base 8, and the valve seat 5 is connected to the connecting base 8. The separate design of the base 9 and the connecting base 8 makes the two components more independent, facilitating disassembly and assembly. Specifically, the valve seat 5 is provided with a plurality of downwardly extending and hollow second pins 24. The inner peripheral wall of the second pins 24 is provided with threads, and the opening of the second pins 24 faces the connecting base 8. The connecting base 8 is provided with a plurality of second mounting holes 25 corresponding to the second pins 24. One end of the bolt passes through the second mounting hole 25 and is threadedly connected to the second pin shaft.

[0050] The valve seat 5 is provided with a mounting port 23, and the connecting seat 8 is provided with a through hole 26. The through hole 26 is positioned directly opposite the mounting port 23. An arc-shaped protrusion 27 is provided circumferentially on the outer side of the through hole 26. The arc-shaped protrusion 27 is used to limit the circumferential movement of the mounting port 23. The contact between the arc-shaped protrusion 27 and the outer side of the mounting port 23 ensures that the connecting seat 8 and the valve seat 5 are axially aligned.

[0051] like Figures 11-13 As shown, the connecting seat 8 is further provided with a number of connecting holes 30, the inner peripheral wall of the connecting hole 30 is provided with threads, the opening of the connecting hole 30 faces the base 9, and the base 9 is provided with a number of third mounting holes 31 corresponding to the connecting holes 30. One end of the bolt passes through the third mounting hole 31 and is threadedly connected to the connecting hole 30.

[0052] like Figures 9-13As shown, preferably, a guide assembly is provided between the base 9 and the connecting seat 8. The guide assembly includes two second slots 28 disposed on the connecting seat 8 and two second blocks 29 disposed on the base 9. The second slots 28 and the second blocks 29 cooperate to align the connecting hole 30 with the corresponding third mounting hole 31. Before tightening the bolts, the connecting seat 8 and the base 9 are initially aligned by the cooperation of the second slots 28 and the second blocks 29, ensuring that the third mounting hole 31 and the connecting hole 30 are roughly aligned, reducing manual adjustment time. Then, the bolts are screwed into the threads after passing through the pre-aligned third mounting hole 31 and the connecting hole 30, achieving the final fixation between the base 9 and the connecting seat 8.

[0053] like Figure 14 and Figure 16 As shown, in one embodiment of this disclosure, the driving component 13 is a motor, and the output shaft of the motor is connected to a first gear 16. The driving component 13 is connected to the water distribution valve plate 10 through a transmission assembly. Specifically, the transmission assembly includes a transmission shaft and a transmission gear meshing with the first gear 16. The water distribution valve plate 10 is provided with a hollow connecting pin 15. One end of the transmission shaft is located in the connecting pin 15, and the other end is connected to the transmission gear. In this way, the rotation control of the water distribution valve plate 10 by the motor is realized.

[0054] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
