Abstract

A clothes treating device includes a clothes accommodation part for accommodating clothes or laundry, a water supply pipe for supplying water into the clothes treating device, and a drain pipe for discharging water to the outside of the clothes treating device. A pump assembly generates a flow of water inside the water supply pipe and the drain pipe by using the rotation of a motor. The flow of water is generated only in one of the water supply pipe and the drain pipe depending on the rotating direction of the motor.

First claim

What is claimed is:

1. A clothes treating apparatus, comprising:
a water supply pipe configured to supply water to an inside of the clothes treating apparatus;
a water discharge pipe configured to discharge the water from the clothes treating apparatus; and
a pump assembly configured to generate flow of the water inside the water supply pipe or inside the water discharge pipe, using rotation of a motor, and
wherein the pump assembly comprises:
a wheel that is configured to be rotated by the motor;
a pair of clutches provided on both sides of the wheel, respectively, wherein each of the pair of clutches is configured to rotate independently from each other with respect to the wheel;
a pair of shafts fixed to the pair of the clutches, respectively;
a pair of impellers connected with each of the pair of shafts and configured to rotate with rotation of a respective one of the pair of clutches; and
a connecting part mounted rotatably with respect to the wheel and configured to transmit a rotational force of the wheel to a respective one of the pair of clutches based on the rotational direction of the motor,
wherein the pair of clutches comprises:
a first clutch provided on one side of the wheel;
a second clutch provided on the other side of the wheel; and
a pair of projections respectively projected from the first clutch and the second clutch toward the wheel and configured to rotate the connecting part with respect to the wheel, and
wherein the connecting part comprises a first connecting arm and a second connecting arm that are spaced a preset distance apart from a center of rotation of the wheel and symmetrically arranged with respect to the center of rotation of the wheel, and
wherein each of the connecting arms comprises:
a connecting bar rotatably coupled to the wheel and provided in parallel to the pair of shafts;
a first hand provided on one end of the connecting bar; and
a second hand provided on the other end of the connecting bar, wherein
the first hand is configured to contact the first clutch to rotate the first clutch, and the second hand is configured to contact the second clutch to rotate the second clutch, and
wherein the flow of the water is generated only in the water supply pipe or only in the water discharge pipe depending on a rotational direction of the motor.

2. The clothes treating apparatus of claim 1 , wherein the pump assembly comprises,
each of the pair of clutches having a rotational center that is coaxial with the rotational center of the wheel, and
wherein the pair of shafts are fixed to the rotational centers of the pair of clutches, respectively.

3. The clothes treating apparatus of claim 1 , wherein:
the first hand contacts the first clutch when the motor is rotated in a first direction,
the second hand does not contact the second clutch when the motor is rotated in the first direction,
the first hand does not contact the first clutch when the motor is rotated in a second direction opposite to the first direction, and
the second hand contacts the second clutch when the motor is rotated in the second direction.

4. The clothes treating apparatus of claim 1 ,
wherein the pair of projections comprises a first projection projected towards the wheel and configured to contact the first hand, and a second projection projected towards the wheel and configured to contact the second hand.

5. The clothes treating apparatus of claim 4 wherein the first clutch comprises two first projections symmetrically arranged with respect to a rotational center of the first clutch, and the second clutch comprises two second projections symmetrically arranged with respect to a rotational center of the second clutch.

6. The clothes treating apparatus of claim 4 , wherein each of the first and second projections comprises:
a contact surface that is configured to come into contact with the first hand or the second hand; and
a collision surface that is configured to collide with the first hand or the second hand.

7. The clothes treating apparatus of claim 6 wherein the contact surface has a larger area than the collision surface.

8. The clothes treating apparatus of claim 6 , wherein the first hand and the second hand of each of the connecting arms are perpendicular with each other.

9. The clothes treating apparatus of claim 8 , wherein each of the first and second hands comprises a planar surface provided in a predetermined first area and a curved surface provided in a second area.

10. The clothes treating apparatus of claim 9 , wherein when the wheel is rotated in one direction, the planar surfaces of the first hands contact the contact surfaces of the first projections, respectively, and the second hands do not contact the second projections.

11. The clothes treating apparatus of claim 10 , wherein when the wheel is rotated in a reverse direction opposite to the one direction, the planar surfaces of the second hands contact the contact surfaces of the second projections and the first hands do not contact the first projections.

12. The clothes treating apparatus of claim 10 , wherein when the wheel is rotated in a reverse direction opposite to the one direction after being rotated in the one direction for a preset time period, the curved surfaces of the first hands collide with the collision surfaces of the first projections and the connecting bars are then rotated.

13. The clothes treating apparatus of claim 12 , wherein the rotation of the connecting bars results in contact between the planar surfaces of the second hands and the contact surfaces of the second projections, and the first hands do not contact the first projections.

14. The clothes treating apparatus of claim 1 , further comprising:
a steam supply device configured to supply steam into a clothes-accommodation unit of the clothes treating apparatus; and
a heat pump configured to generate hot air for supply to the clothes-accommodation unit.

15. The clothes treating apparatus of claim 1 , wherein the pair of impellers comprises:
a first impeller in fluid communication with the water supply pipe; and
a second impeller in fluid communication with the water discharge pipe, wherein
the first impeller and the second impeller are not rotated at the same time.
