Washing machine and control method thereof
A washing machine and a control method thereof are provided. More particularly, a washing machine of supplying a detergent automatically to a detergent mixing tub using a detachable detergent supply container, or of supplying a softening agent automatically to a softening agent mixing tub using a detachable softening agent supply container, and a method of controlling the washing machine are disclosed. Some of the disclosed embodiments provide a washing machine of supplying a detergent automatically to a washing tub using a detergent supply unit with a detergent supply container, and of supplying a softening agent automatically to the washing tub using a softening agent supply unit with a softening agent supply container, and a method of controlling the washing machine.
1. A detergent supply unit comprising:
a housing;
a detergent supply container installable in an accommodating portion of the housing, and configured to accommodate detergent;
a detergent mixing tub formed into the housing and having an opening, a part of the detergent is mixed with water in the detergent mixing tub;
a pump configured to supply the part of the detergent from the detergent supply tub to the detergent mixing tub; and
a motor configured to transfer a driving force for driving the pump,
wherein the pump comprises a pump handle configured to transmit the driving force from the motor, and a detergent discharging opening, formed at one end of the pump handle to discharge the part of the detergent into the opening of the detergent mixing tub,
wherein the pump handle performs a reciprocating motion in an up-down direction by the driving force to discharge the part of the detergent into the opening of the detergent mixing tub while the motor is running,
wherein the pump handle is rotatable around the up-down direction so that a position of the detergent discharging opening is changeable between a top of the detergent mixing tub and a top of one side of the detergent mixing tub while the motor is not running.
2. The detergent supply unit of claim 1 , wherein the pump further comprises a detergent suction tube configured to suck the part of the detergent from the detergent supply container, and
wherein the detergent suction tube is an inside of the detergent supply container.
3. The detergent supply unit of claim 2 , wherein the pump handle is couplable with the detergent suction tube, and disposed outside the detergent supply container.
4. The detergent supply unit of claim 1 , wherein the pump further comprises a pump driving shaft receiving the driving force from the motor, and
wherein a part of the pump driving shaft is exposed to the outside of the detergent supply container.
5. The detergent supply unit of claim 1 , wherein the motor further comprises:
a driving shaft transferring the driving force through a belt; and
a driven shaft receiving the driving force through the belt, wherein the driving force is transferred to the pump driving shaft through the driven shaft.
6. The detergent supply unit of claim 5 , wherein a part of the driven shaft is exposed to the outside, and
the part of the driven shaft comprises a connector guide connected to the pump driving shaft.
7. The detergent supply unit of claim 1 , wherein the detergent mixing tub receives the water from a water supply unit.
8. The detergent supply unit of claim 7 , wherein detergent mixed water mixed in the detergent mixing tub is discharged by a mixed water hose connected to a bottom of the detergent mixing tub.
9. The detergent supply unit of claim 8 , wherein the detergent mixed water discharged through the mixed water hose is discharged to the washing tub through a detergent case.
10. The detergent supply unit of claim 1 , further comprising:
a protrusion formed in the accommodating portion of the housing;
a catching portion formed in the detergent supply container to correspond to the protrusion; and
a release button,
wherein when the release button is pressed, the protrusion is spaced apart from the catching portion.
11. The detergent supply unit of claim 1 , wherein the detergent accommodated in the detergent supply container is supplied to one of the detergent mixing tub and the washing tub by manual pumping.
