[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-3 This utility model provides an embodiment of an inner water pipe assembly, including an inner water pipe body 1. The inner water pipe body 1 is a key component for conveying cleaning water within a dishwasher. Its internal water flow channel ensures water circulation within the dishwasher, providing the necessary hydraulic conditions for washing dishes. One end of the inner water pipe body 1 has a water inlet 2, which is used to connect to an external water source or the dishwasher's water inlet pipe, allowing cleaning water to smoothly enter the inner water pipe body 1. The other end of the inner water pipe body 1 has a water outlet 3, which discharges the water conveyed through the inner water pipe body 1. Place it inside the dishwasher or other parts that require water to perform the dishwashing operation. The outer wall of the inner water pipe body 1 is equipped with a housing 4. The housing 4 is used to place and discharge the descaling material. The housing 4 contains descaling material, which can effectively remove the scale generated on the inner wall of the inner water pipe body 1 and inside the dishwasher, ensuring the normal operation of the inner water pipe assembly and extending its service life. The housing 4 is equipped with a discharge assembly, which is responsible for controlling the release of the descaling material to achieve the function of periodic descaling of the inner water pipe body 1.

[0030] Reference Figure 3 The discharge assembly includes a rotating shaft 5, which, as a key rotating component, provides power transmission and support for the entire discharge process. The shaft 5 is rotatably connected to the inner wall of the housing 4 at its center. This rotatable connection allows the shaft 5 to rotate stably within the housing 4, ensuring the normal operation of the discharge assembly. An impeller 6 and a rotating shell 7 are fixedly connected to the shaft 5. The impeller 6 drives the shaft 5 to rotate under the action of water flow, while the rotating shell 7, in conjunction with other components, controls the discharge of the descaling material. A sealing ring 8 is installed on the outer side of the rotating shell 7 to prevent leakage of the descaling material. In areas where it is not needed, to ensure the sealing of the discharge assembly, a discharge port 9 is provided vertically on the rotating shell 7 and the sealing ring 8. The discharge port 9 is designed so that when the rotating shell 7 is rotated to a specific position, the descaling material can be discharged through the discharge port 9. A discharge pipe 10 is installed directly below the shell 4. The discharge pipe 10 provides a channel for the descaling material to be discharged from the shell 4 and enter the inner water pipe body 1. An electromagnetic one-way valve 11 is installed at the bottom of the discharge pipe 10. The electromagnetic one-way valve 11 can accurately control the discharge direction and timing of the descaling material under the action of the control signal, and avoid the reverse flow of water.

[0031] Reference Figure 3 The interior of the shell 4 is inclined. The inclined design is conducive to the accumulation of the descaling material towards the discharge port 9 under the action of gravity, making it easier for the descaling material to enter the inner water pipe body 1 through the discharge port 9 and the discharge pipe 10 during the discharge process, thereby improving the discharge efficiency and stability.

[0032] Reference Figure 3 The upper side of the housing 4 is provided with a feed port, which allows users to easily add descaling material into the housing 4, ensuring a reserve of descaling material to maintain the long-term effective descaling function of the discharge component. The outlet 3 is provided with a sealing cap, which is connected to the outlet 3 by a thread. The threaded sealing cap can be easily opened and closed when maintenance or inspection of the outlet 3 is required, while ensuring the sealing of the outlet 3 under normal working conditions to prevent leakage and other abnormalities.

[0033] Reference Figure 3 The sealing ring 8 and the inner wall of the housing 4 abut against each other, and this tight contact effectively prevents the descaling material from leaking out from the gap between the rotating shell 7 and the housing 4. This ensures the sealing of the discharge assembly during operation and prevents the descaling material leakage from adversely affecting other parts of the dishwasher.

[0034] Reference Figure 3 The electromagnetic check valve 11 opens towards the inside of the inner water pipe body 1, ensuring that the descaling material can be accurately discharged into the inner water pipe body 1 when the electromagnetic check valve 11 is open. This prevents backflow into the discharge pipe 10 or other unwanted areas, thus ensuring that the descaling material can effectively remove scale from the inner water pipe body 1.

[0035] Reference Figure 2 The impeller 6 is positioned perpendicular to the water flow direction. This vertical positioning allows the impeller 6 to receive the impact force of the water flow to the maximum extent, effectively converting the kinetic energy of the water flow into rotational power. Furthermore, the impeller 6 has a wear-resistant coating on its surface. This coating reduces wear on the impeller 6 during long-term contact with water flow and potential impurities, extending its service life and ensuring the stable operation of the discharge assembly.

[0036] Reference Figures 1-3 The descaling material is a mixture of granular citric acid and porous ceramic balls. Citric acid has excellent scale-dissolving ability, reacting chemically with calcium and magnesium ions in the scale to decompose and remove it. The porous ceramic balls increase the overall surface area of ​​the descaling material, which helps the citric acid to work more effectively and also adsorbs some impurities generated during the descaling process, thus improving the descaling effect.

[0037] Reference Figure 2The inner wall of the inner water pipe body 1 is coated with a polytetrafluoroethylene (PTFE) coating. The PTFE coating has extremely low surface energy, allowing water to flow more smoothly within the inner water pipe body 1, reducing water flow resistance and improving the dishwasher's cleaning efficiency. Simultaneously, it also has excellent corrosion resistance, preventing the inner water pipe body 1 from being corroded by chemicals that may be present in the water, thus extending its service life.

[0038] Working principle: When supplying water to the dishwasher using the internal water pipe structure, the inlet 2 is connected to the external water supply or the dishwasher's water inlet pipe, and the outlet 3 is connected to the dishwasher's internal cavity or other parts requiring water. Then, the water flow is turned on. As the water flows inside the internal water pipe body 1, the flow rate drives the impeller 6 to rotate. The rotation of the impeller 6 drives the rotating shaft 5 to rotate. When the rotating shaft 5 rotates, it drives the rotating shell 7 and the sealing ring 8 to rotate. When the discharge port 9 at the bottom of the rotating shell 7 and the sealing ring 8 rotates into the vertical shell 4, the descaling material inside the shell 4 is discharged into the discharge pipe 10 under the action of the inclined structure inside the shell 4 and gravity. At this time, if it is the first wash, the electromagnetic one-way valve 11 will open to discharge the descaling material and clean the scale inside the internal water pipe body 1. If it is not the first wash, it will not open. The descaling material cleans the scale on the inner wall of the internal water pipe body 1 and flows out through the water flow.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
