[0024] In this dishwasher filter, a water cup 1 is loaded into an external dishwasher. When working, external water is added to the water cup 1 to immerse the medical stone in the storage frame 3. The medical stone can be used to adjust the pH value in both directions, and can also remove harmful substances such as chlorine, sulfate, and heavy metal ions in the water to improve the water quality. The spray mechanism in the dishwasher draws water from the water cup 1 from the first water outlet 11 to rinse the tableware in the dishwasher. The rinsed water drops on the bottom surface of the dishwasher, and the water is collected in the transition tube 22 through the confluence plate 21. The transition tube 22 can guide the water to The water is released from the bottom of the first water outlet 11, and the water first passes through the preliminary filtration of the lower filter cylinder 23, and then passes through the filter cover 24 arranged on the outside of the lower filter cylinder 23 to further filter before flowing out. In this way, the water is continuously drawn out from the water cup 1, and then flows back to the water cup 1 for filtration circulation. In this process, since the first water outlet 11 is located above the storage frame 3, the medical stone is always ensured to be immersed in the water, and the drawn water is ensured to pass through the medical stone before being drawn out. After the water is soaked by the medical stone, the pH value of the water quality is effectively improved, the inside of the dishwasher is better protected, and the washing effect is improved.

[0025] Before the water flows into the confluence plate 21, the water can be initially filtered to reduce the food residues that flow directly from the confluence plate 21 into the transition tube 22. In this embodiment, the top side of the confluence plate 21 is connected with an upper filter plate 25, and the top end of the transition tube 22 is connected with an upper filter tube 26. The upper filter tube 26 passes through the upper filter plate 25 upward. In practical applications, the transition tube 22 and the upper filter tube 26 can be an integrally formed structure to improve the convenience of production.
