Washing machine deceleration clutch anti-seepage device and washing machine thereof

The invention relates to a washing machine deceleration clutch anti-seepage device and a washing machine thereof and relates to the technical field of washing machines. The anti-seepage device overcomes the shortcoming that a lip fails due to the fact that silt enters a water seal inner clip and a dewatering shaft of a deceleration clutch of the washing machine. The device comprises the dewatering shaft and a large water seal connected with the dewatering shaft through a soft lip opening, and an outer clip of the large water seal is connected with an outer barrel. The device is characterized by further comprising an anti-seepage part, and an air cavity with one end open is formed between the anti-seepage part and the large water seal. By means of the technical scheme, the air cavity with one end open is formed between the anti-seepage part and the large water seal by arranging the anti-seepage part, a sealing cavity is formed during working of the washing machine, water or silt is effectively prevented from entering the inner lip opening of the water seal, and the whole service life of the deceleration clutch of the washing machine and the washing machine are prolonged. The probability that the washing machine fails due to the fact that the large water seal of the clutch has water seepage is effectively reduced, after-sales maintenance cost is greatly reduced, resources are saved, and the design concept of the water seal is greatly enriched.
