Description

Technical Field

[0001] The utility model relates to the field of dishwashers, in particular to a drainage pipeline system for a dishwasher. Background Art

[0002] There are many deficiencies in the design of some existing dishwasher drainage systems. Some of them do not have a drainage pump and rely only on their own gravity for drainage, which results in relatively low drainage efficiency and users need to wait for a long time to complete the drainage process. More seriously, the pipeline design of these systems is often not reasonable enough and lacks a necessary anti-backflow mechanism, which easily causes the backflow of sewage. This backflow will not only cause secondary pollution inside the dishwasher, affecting the cleanliness of tableware, but also may damage other components of the dishwasher and shorten its service life.

[0003] In addition, these systems usually do not have an overflow drainage pipeline. When the water level in the main washing tank is too high, the water cannot be discharged in time, further increasing the pollution risk of the dishwasher. In the long run, it will not only affect the normal use of the dishwasher, but also pose a potential threat to the health of users.

[0004] Therefore, it is necessary to provide a drainage pipeline system for a dishwasher to solve the above technical problems. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a drainage pipeline system for a dishwasher.

[0006] A drainage pipeline system for a dishwasher provided by the utility model includes a machine body, a main washing tank, a waste water tank and a drainage pump are installed in the machine body. The water inlet end of the drainage pump is communicated with the bottom of the main washing tank through a first pipeline. The water outlet end of the drainage pump is connected with an anti-siphon three-way through an L-shaped water pipe. The anti-siphon three-way is connected with a first three-way pipe through a first vertical pipe. One water outlet end of the first three-way pipe is communicated with the bottom of the waste water tank through a second pipeline. The other water outlet end of the first three-way pipe is connected with a second three-way pipe through an S-shaped pipeline. One water outlet end of the second three-way pipe is connected with a drain pipe for connecting with a sewer. Overflow ports are arranged on both the main washing tank and the waste water tank. The other water outlet end of the second three-way pipe is communicated with the overflow port of the waste water tank through a waste water overflow pipe. The overflow port of the main washing tank is communicated with the waste water tank through a main washing overflow pipe.

[0007] Preferably, the S-shaped pipeline includes a connecting pipe connected with the water outlet end of the first three-way pipe. A first U-shaped pipe is installed at the end of the connecting pipe. A second vertical pipe is installed at the end of the first U-shaped pipe far away from the connecting pipe. A second U-shaped pipe is installed at the top of the second vertical pipe. A third vertical pipe is installed at the end of the second U-shaped pipe far away from the second vertical pipe. The third vertical pipe is communicated with the water inlet end of the second three-way pipe.

[0008] Preferably, the first riser pipe and the connecting pipe are on the same vertical line.

[0009] Preferably, the overflow port of the main washing water tank is at a higher horizontal level than the overflow port of the waste water tank.

[0010] Preferably, the drain pipe is arranged in a vertical state.

[0011] Compared with the related art, the present utility model has the following beneficial effects:

[0012] Efficient drainage: Through the strong suction of the drainage pump and the reasonable pipeline layout, the waste water can be quickly and smoothly discharged from the dishwasher, improving the drainage efficiency of the dishwasher.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0021] Please refer to Figures 1 to 4, A dishwasher drain pipe system, including a body 1, in which a main washing water tank 2, a waste water tank 3, and a drain pump 4 responsible for pumping tasks are ingeniously installed. The water inlet end of the drain pump 4 is tightly connected to the bottom of the main washing water tank 2 through a first pipe 5. Such a design enables the waste water to be effectively pumped out by the strong suction generated by the drain pump 4.

[0022] The pumped waste water then flows into an anti-siphon three-way pipe 7 through an L-shaped water pipe 6. The design of the anti-siphon three-way pipe 7 is ingenious. It ensures the one-way flow of waste water and effectively avoids the occurrence of siphon phenomenon, that is, the situation where waste water is sucked back into the dishwasher due to negative pressure is completely eliminated.

[0023] After the waste water flows out of the anti-siphon three-way pipe 7 smoothly, it will pass through an S-shaped pipeline 11 and finally enter a second three-way pipe 12. The design of the S-shaped pipeline 11 is also excellent. Its tortuous path greatly increases the resistance of waste water backflow and further ensures the smooth discharge of waste water. One water outlet end of the second three-way pipe 12 is connected to the sewer through a drain pipe 13, enabling the waste water to be smoothly discharged into the sewer.

[0024] In addition, the system is also specially provided with a waste water tank 3 for collecting the possibly overflowed waste water. Overflow ports 21 are provided on both the main washing water tank 2 and the waste water tank 3 and are connected through corresponding overflow pipes. Such a design enables the waste water to automatically flow into the waste water tank 3 when the water level in the main washing water tank 2 is too high, thus effectively avoiding the situation of waste water overflowing from the dishwasher. At the same time, the waste water at the bottom of the waste water tank 3 can also be smoothly discharged through the S-shaped pipeline 11 and the drain pipe 13.

[0025] In the design of the entire drain pipe system, the drain efficiency and water flow resistance are fully considered. Through reasonable pipeline layout and diameter selection, the smooth discharge of waste water is ensured, and at the same time, the risks of blockage and backflow are greatly reduced.

[0026] It is worth mentioning that the design of the S-shaped pipeline 11 is particularly complex and delicate. It is first connected to the water outlet end of a first three-way pipe 9 through a connecting pipe 16, and then a first U-shaped pipe 17 is installed at the end of the connecting pipe 16. The end of the first U-shaped pipe 17 far from the connecting pipe 16 is installed with a second riser pipe 18, and the top of the second riser pipe 18 is installed with a second U-shaped pipe 19. The end of the second U-shaped pipe 19 far from the second riser pipe 18 is then connected to the water inlet end of the second three-way pipe 12 through a third riser pipe 20. Such a design not only increases the resistance of waste water backflow but also further ensures the smooth discharge of waste water.

[0027] In addition, the first riser pipe 8 and the connecting pipe 16 are ingeniously designed on the same vertical line. Such a layout is not only beautiful and generous but also helps to optimize the water flow path and improve the drain efficiency.

[0028] Meanwhile, the horizontal height of the overflow port 21 of the main washing water tank 2 is deliberately designed to be higher than that of the overflow port 21 of the waste water tank 3. This design enables the waste water to flow into the waste water tank 3 more smoothly when the water level in the main washing water tank 2 is too high, further enhancing the stability and reliability of the system.

[0029] Finally, the drain pipe 13 is vertically arranged below. This design not only complies with the building code but also helps the smooth discharge of waste water, avoiding the risk of blockage caused by pipe bending. Generally speaking, the design of the dishwasher drain pipe system fully considers the actual usage requirements and various possible risk factors, ensuring the smooth discharge of waste water and the stable operation of the system.

[0030] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
