Abstract

An water supply apparatus and its method of a drum-type washing machine includes a rotation pump for rotating washing water supplied into a tub, and a spray nozzle for spraying washing water supplied from the rotation pump into the drum.

Claims

1. A water supply apparatus of a drum-type washing machine comprising:

a rotation pump for rotating washing water supplied into a tub of a drum-type washing machine; and

a spray nozzle for spraying washing water supplied from the rotation pump into the drum.

2. The apparatus of claim 1, wherein the rotation pump comprises:

an outflow tube through which washing water which has been supplied into the tub is flowed out; and

a rotation tube through which the washing water which has been flowed out is supplied to the spray nozzle.

3. The apparatus of claim 1, wherein the washing water is supplied as much as a predetermined water level.

4. The apparatus of claim 3, wherein the predetermined water level is from the lowest end portion of the tub to the lowest end portion of the drum.

5. The apparatus of claim 1, wherein the spray nozzle is installed at a predetermined region of an upper end portion of the inside the drum.

6. A water supply method of a drum-type washing machine comprising:

supplying washing water into a tub of a drum-type washing machine up to a predetermined upper water level;

rotating the supplied washing water through a rotation pump; and

terminating the washing water supply when a state that a water level of the washing water is higher than a predetermined lower water level is maintained for a predetermined time.

7. The method of claim 6, wherein the predetermined upper water level is from the lowest end portion of the tub to the lowest end portion of the drum.

8. The method of claim 6, wherein the predetermined lower water level is less than the predetermined upper water level.

9. The method of claim 6, wherein said terminating comprises:

comparing a water level of the washing water and the predetermined lower water level;

checking whether the predetermined time elapses when the water level of the washing water is higher than the predetermined lower water level; and

terminating the washing water supply when the predetermined time elapses.

10. The method of claim 9, wherein said comparing comprises:

supplying washing water when the water level of the washing water is lower than the predetermined lower water level.

11. The method of claim 9, wherein said checking comprises:

=

rotating washing water within the predetermined time.
