[0021] The present invention will be further described below with reference to the accompanying drawings.
[0022] The water system structure of this utility model's twin-drum washing machine includes a water inlet structure, a drainage structure, and an overflow structure. The water inlet structure includes a water inlet valve 10, a four-way pipe 11, a left spray head 12, and a right spray head 13. A first water inlet pipe 14 and a second water inlet pipe 15 are connected to the water inlet valve 10. The four-way pipe 11 includes a first interface, a second interface, a third interface, and a fourth interface. The first water inlet pipe 14 and the second water inlet pipe 15 are respectively connected to the first interface and the second interface. A third water inlet pipe 16 is connected to the third interface, and the other end of the third water inlet pipe 16 is connected to the right spray head 13. A fourth water inlet pipe 17 is connected to the fourth interface, and the other end of the fourth water inlet pipe 17 is connected to the left spray head 12. Water sprayed from the right spray head 13 and the left spray head 12 is sprayed into the washing machine drum.

The fifth interface connects to the drain valve 21, the sixth interface connects to the air chamber 23, and the seventh interface connects to the bottom of the washing machine tub. The drain valve 21 and the drain collection box 22 are connected by a drain pipe 24. A drain pipe (not shown) is externally connected to the drain collection box 22. When the washing machine drains, water in the washing machine tub flows through the drain tee 20 into the drain valve 21. At this time, the drain valve 21 operates, allowing water to flow through the drain pipe 24 into the drain collection box 22. The bottom surface of the drain collection box 22 is designed with a slope to facilitate the merging of water from the left and right tubs and their simultaneous discharge through the drain pipe to the outside of the washing machine.

An overflow outlet is formed above the washing machine tub, and the rubber component 30 is sealed and installed at the overflow outlet. One end of the connecting pipe 31 is connected to the overflow outlet, and the other end is connected to the overflow collection box 32. The overflow collection box 32 and the drain collection box 22 are connected by the overflow corrugated pipe 33. When the washing machine is operating, if the water level in the tub exceeds the set inlet level, the overflowing water will flow through the overflow outlet into the overflow collection box 32, and then through the overflow corrugated pipe 33 into the drain collection box 22, before being discharged outside the washing machine.
[0025] The internal piping of the overflow collection box 32 is arranged in a continuous U-shape. When the washing machine enters the user's home, during use, as the overflow water increases, it will...
