1results about How to "Improve cleaning ratio" patented technology

Embodiments of the present application provide a laundry treating apparatus including a tub assembly and a circulation system. The tub assembly is provided with a laundry treating cavity and a drain opening communicating with the laundry treating cavity. The circulation system includes a drain pump having a first outlet and a water inlet, a drain passage communicating the drain opening with the water inlet, and a first passage having a water inlet end communicating with the first outlet and a water outlet end facing the drain passage. During the process of the drain pump pumping water into the first passage, the water in the first passage flows at a high speed, and the water flowing out of the water outlet end of the first passage has a flow interference effect on the water and the detergent in the drain passage, which is conducive to promoting the dissolution of the detergent in the drain passage. Since the drain passage communicates with the laundry treating cavity through the drain opening, the dissolved detergent will enter the laundry treating cavity along with the water through the drain opening to clean the laundry, thereby helping to improve the cleaning ratio.
