  • the bottom wall of the first dissolution chamber 21 is formed as the inverted cone, and the water flows along the bottom wall of the first dissolution chamber 21, such that a swirling water flow can be formed in the first dissolution chamber 21, thereby promoting the flowing of water, so as to achieve sufficient dissolution of the detergent in the first dissolution chamber 21 and improve dissolution efficiency of the detergent, thereby making the clothes sufficiently cleaned and improving a cleaning effect of the washing machine.
  • the first water outlet 211 is disposed in the bottom wall of the first dissolution chamber 21, and the water in the first dissolution chamber 21 flows out from the first water outlet 211.
  • the first water outlet 211 may be disposed at a bottom end of the bottom wall of the first dissolution chamber 21.
  • the first water outlet 211 may be disposed at the lowest point of the bottom wall of the first dissolution chamber 21, such that the water in the first dissolution chamber 21 flows to the first water outlet 211 and forms a vortex at the first water outlet 211, which can not only facilitate the dissolution of the detergent in the first dissolution chamber 21, but also ensure that the detergent and water in the first dissolution chamber 21 are completely discharged to avoid residues in the first dissolution chamber 21.
  • the impeller 3 is rotatably disposed in the first dissolution chamber 21 and disposed to a side wall of the first dissolution chamber 21, and the impeller 3 is arranged corresponding to the flushing port 16 in an up-and-down direction, such that the water in the water input box 1 flows downwards through the flushing port 16 and is directed towards the impeller 3 to drive the impeller 3 to rotate, so as to agitate the detergent in the first dissolution chamber 21, thereby promoting the dissolution of the detergent and dissolving the detergent completely. In such a way, the dissolution rate of the detergent is raised, and thus the cleaning effect of the washing machine is improved.
  • the impeller 3 can be rotated by itself under the action of the water flow, and no external force is required to drive the impeller 3 to rotate.
  • the impeller 2 may be disposed to a rear side wall of the first dissolution chamber 21; as illustrated in Figs. 4 and 6 , the impeller 3 may be disposed to a left side wall of the first dissolution chamber 21.
  • the flushing port 16 is located above the impeller 3 to allow the water to rush towards the impeller 3 directly from the flushing port 16.
  • the impeller 3 has an axis extendable along a horizontal direction and located below the flushing port 16, that is, the impeller 3 is horizontally arranged.
  • the axis of the impeller 3 may be perpendicular to the side wall of the first dissolution chamber 21, to facilitate the installation and assembly of the impeller 3, and moreover, the water rushes from the flushing port 16 to the impeller 3, which is also conductive to driving the impeller 3 to rotate. Meanwhile, under the action of gravity, the water rushes vertically downwards from the flushing port 16 towards blades of the impeller 3, thereby further enhancing the impact of the water flow on the blades to ensure a rotation effect of the impeller 3.
  • the bottom wall of the first dissolution chamber 21 is formed as the inverted cone, and the water flows along the bottom wall of the first dissolution chamber 21, whereby the swirling water flow can be formed in the first dissolution chamber 21, and hence the detergent in the first dissolution chamber 21 is sufficiently dissolved, thereby improving the dissolution efficiency of the detergent and making the clothes sufficiently cleaned, so as to improve the cleaning effect of the washing machine.
