The shower pipe 5 injects a shock water flow into the water inlet passage 3, and a baffle 32 is disposed on the side wall of the water inlet passage 3 opposite to the impact direction of the impact water flow. As shown in FIG. 4, the spray port 31 is located at the water inlet passage 3. Upper side wall, the lower side of the water inlet channel 3 The baffle 32 is disposed on the wall. When the detergent solution enters the water inlet passage 3, it is impacted by the water flow. The baffle 32 prevents the detergent solution from directly flowing out of the water outlet 10, and generates a rotating water flow in the water inlet passage 3, washing The solution solution is contacted with the air in the water inlet passage 3 to perform secondary dissolution foaming (one-time dissolution foaming in the detergent box), so that the detergent is fully dissolved and foamed in the water inlet passage 3, and the foam is rich and delicate. The foam is more likely to penetrate into the clothes and improve the washing rate of the clothes. In addition, the water jet impact foaming of the detergent solution requires air to be in contact with it, so the detergent solution of the embodiment does not fill the entire water inlet passage, but leaves the upper space so that the air can enter and participate in the detergent. bubble.

In actual use, due to the presence of the baffle, when the washing machine stops entering the water, the water at the bottom is blocked by the baffle and cannot be discharged from the water outlet. In order to drain the remaining water, a small hole can be made in the side wall of the passage near the baffle. During the washing process, although the small holes also effluent, the rotating water flow formed in the water inlet passage makes the water output at the small holes not large, and only a small amount of water flows from the small holes into the drum, so the arrangement of the small holes is The effect of detergent on the foaming in the inlet channel is minimal and does not affect the water flow at the outlet.
