Abstract

An improved washing machine equipped with a pulsator to prevent entanglement of laundry capable of efficiently preventing entanglement of laundry by preventing clothes being washed from gathering at the central portion in the inner tub of the washing machine, which includes an upper blade having a upwardly extending ejection hole, the upwardly extending ejection hole being formed at a central portion of the upper blade; a lower blade disposed below the upper blade; an improved pulsator disposed between the upper blade and the lower blade for transferring a driving force from the lower blade to the upper blade and having a plurality of spaced-apart support bushings for forming a washing water flow path between the upper blade and the lower blade; and an inner tub having a washing water guide section formed at a periphery of the lower blade and the support bushings.

Claims

1. A washing machine equipped with a pulsator to prevent entanglement of laundry, comprising:

an upper blade having a upwardly extending ejection hole, said upwardly extending ejection hole being formed at a central portion of said upper blade;

a lower blade disposed below the upper blade;

an improved pulsator disposed between the upper blade and said lower blade for transferring a driving force from the lower blade to the upper blade and having a plurality of spaced-apart support bushings for forming a washing water flow path between the upper blade and the lower blade;

an inner tub having a washing water guide section formed at a periphery of the lower blade and the support bushings; and

pumping means disposed at a predetermined portion of said inner tub for pumping washing water to the ejecting hole.

2. The washing machine of claim 1, wherein said pumping means is disposed at an inner portion of the washing water flow path disposed at a periphery of the lower blade.

3. The washing machine of claim 1,wherein said washing water ejecting port is disposed at a lower portion of the lower blade.

4. A washing machine equipped with a pulsator to prevent entanglement of laundry, comprising:

an upper blade having an ejecting hole formed at its central portion;

a lower blade disposed below said upper blade;

a plurality of support bushings disposed between the upper blade and said lower blade for connecting the upper and lower blades and for transferring a driving force from the lower blade to the upper blade and spaced apart so as to form an upper portion washing water flow path between the upper blade and the lower blade; and

a washing water flow section formed at a lower portion of an outer periphery of the upper blade and extended to a lower central portion of the lower blade;

wherein said pulsator includes a plurality of ribs integrally formed with the lower surface of the washing water flow section extending from the outermost lower portion of the upper blade and the inner end portion of the washing water flow section.
