In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a take labyrinth water inlet spacer for dish washer, includes the spacer body, spacer body lower extreme an organic whole is provided with labyrinth seal structure, labyrinth seal structure includes interior sealed limit and outer sealed limit, be provided with the embedded recess of an impeller between interior sealed limit and the outer sealed limit.
The utility model discloses further set up to: the inner sealing edge and the outer sealing edge are integrally arranged with the support sleeve body, the embedded groove of the impeller is an annular groove, and an opening of the embedded groove of the impeller is arranged downwards.
The utility model discloses still further set up to: the outer surface upper end position of propping cover body has set gradually first step face and second step face from last to down, first step face is close to second step face department and is provided with water inlet rubber tube positioning groove.
The utility model discloses still further set up to: the supporting sleeve is internally provided with a first water inlet through hole and a second water inlet through hole from top to bottom in sequence, and the diameter of the first water inlet through hole is larger than that of the second water inlet through hole.
The utility model discloses still further set up to: and a conical flow guide surface is arranged at the joint of the first water inlet through hole and the second water inlet through hole.
The utility model discloses still further set up to: the lower end surface of the outer sealing edge is lower than that of the inner sealing edge.
The utility model has the advantages that: compared with the prior art, the utility model has more reasonable structure, the impeller sealing part of the prior impeller is embedded in the embedded groove of the impeller, and the impeller forms sealing with the inner wall surface of the embedded groove of the impeller in the water inlet support sleeve through the impeller sealing part; simple structure, good sealing performance at the inner and outer diameters of the edge of the impeller, small water inlet flow loss and good practicability.
The invention is further described with reference to the drawings and the specific embodiments.
