Title: DRAINAGE STRUCTURE AND WASHING MACHINE PROVIDED WITH DRAINAGE STRUCTURE
Abstract:
A drainage structure and a washing machine provided with the drainage structure. The drainage structure comprises a water inlet (1), a water outlet (2) and an impeller accommodating cavity (3). The impeller accommodating cavity (3) comprises a front end face (31) and a circumferential wall (32). The water inlet (1) is arranged in the centre of the front end face (31) and is in communication with the impeller accommodating cavity (3). The water outlet (2) is arranged on the circumferential wall (32). The front end face (31) is provided with a guiding-out groove (311). The guiding-out groove (311) extends from the water inlet (1) to the water outlet (2). Since, during the process of washing, foreign matter, such as accessories of clothing or small articles left in the clothing will fall into a space between inner and outer drums via a gap between impellers, when a washing machine drains water, the foreign matter enters the guiding-out groove (311) from the water inlet (1) of the drainage structure along with the water flow, and is discharged from the water outlet (2) along the guiding-out groove (311), thus effectively preventing the problem that the foreign matter jams the impellers when entering the impellers of a drainage pump, causing the drainage pump not to work, and water in the washing machine not to be smoothly drained.
