Abstract
The utility model discloses a protection structure of a small oil seal and an impeller washing machine. The protection structure of the small oil seal comprises a washing shaft, a dewatering shaft, an impeller, the small oil seal and an inner barrel connection disc, wherein the impeller comprises a center shaft sleeve, an annular rib and a first wave prevention rib; the impeller structurally forms a first interval, a waterproof space, a second interval and a first wave prevention space. The energy of water waves when the impeller pokes water is reduced by the utilization of the first wave prevention space, and impact on the first interval from the energy of the water waves is reduced, so that when the water inside the impeller washing machine passes through the first interval, then enters the waterproof space and compresses the sealed air, the liquid face fluctuation tends to be slow, the compressed air blocks the water effectively, the small oil seal of a clutch is separated from the water in the impeller washing machine, and it is avoided that as water enters the clutch from the small oil seal, the clutch is abandoned and the performance of the whole impeller washing machine is affected. The protection structure of the small oil seal is low in cost and good in waterproof effect.
