Abstract

A laundry treating apparatus includes a first nozzle water supply conduit which is disposed, on the gasket, in the one side with respect to the vertical line and guides water discharged through the first circulation port to the pair of first nozzles; and a second nozzle water supply conduit which is disposed, on the gasket, in the other side with respect to the vertical line and guides water discharged through the second circulation port to the pair of second nozzles.

First claim

What is claimed is:

1. A laundry treating apparatus comprising:
a cabinet having a front surface that defines an input port;
a tub located in the cabinet, the tub having a front surface that defines a tub opening;
a drum located in the tub and configured to rotate relative to the tub;
a gasket having an inner circumferential surface that defines a channel that extends between the input port of the cabinet and the tub opening;
a pair of first nozzles located at the inner circumferential surface of the gasket and configured to spray water into the drum, the pair of first nozzles being arranged at a first side with respect to a vertical line passing through a center of the gasket;
a pump configured to pump water discharged from the tub, the pump comprising a first circulation port that is configured to discharge water to provide water to the tub; and
a first nozzle water supply conduit that is located at the first side with respect to the vertical line; and
a first circulation conduit having a first end configured to connect to the first circulation port of the pump and a second end configured to connect to the first nozzle water supply conduit,
wherein the first nozzle water supply conduit includes:
a first connection port configured to connect to the second end of the first circulation conduit;
a first conduit portion that extends from the first connection port along an outer circumferential surface of the gasket; and
a pair of first nozzle water supply ports that protrude from the first conduit portion toward the gasket, that are coupled to the gasket, and that are connected to the pair of first nozzles, respectively.

2. The laundry treating apparatus of claim 1 , further comprising:
a pair of second nozzles located at the inner circumferential surface of the gasket and configured to spray water into the drum, the pair of second nozzles being arranged at a second side with respect to the vertical line opposite to the first side;
a second nozzle water supply conduit that is located at the second side with respect to the vertical line; and
a second circulation conduit having a first end configured to connect to a second circulation port of the pump that is configured to discharge water to provide water to the tub and a second end configured to connect to the second nozzle water supply conduit, and
wherein the second nozzle water supply conduit includes:
a second connection port configured to connect to the second end of the second circulation conduit;
a second conduit portion that extends from the second connection port along the outer circumferential surface of the gasket; and
a pair of second nozzle water supply ports that protrude from the second conduit portion toward the gasket, that are coupled to the gasket, and that are connected to the pair of second nozzles, respectively.

3. The laundry treating apparatus of claim 2 , further comprising:
a lower balancing weight configured to couple to the tub and located at a lower side of the gasket, the lower balancing weight extending to each of the first side and the second side with respect to the vertical line,
wherein the first nozzle water supply conduit is located above the lower balancing weight at the first side, and
wherein the second nozzle water supply conduit is located above the lower balancing weight at the second side.

4. The laundry treating apparatus of claim 2 ,
wherein the second connection port protrudes from the second conduit portion in a direction away from the gasket and defines an inlet that is configured to communicate with the second circulation conduit.

5. The laundry treating apparatus of claim 2 , wherein the pair of first nozzles are arranged about the center of the gasket and spaced apart from each other along the inner circumferential surface of the gasket,
wherein the pair of second nozzles are arranged about the center of the gasket and spaced apart from each other along the inner circumferential surface of the gasket, and
wherein the pair of first nozzles are symmetric to the pair of second nozzles with respect to the vertical line passing through the center of the gasket.

6. The laundry treating apparatus of claim 2 , wherein the gasket comprises:
a pair of first insertion conduits that protrude from the outer circumferential surface of the gasket, that are located at the first side with respect to the vertical line, and that are configured to receive the pair of first nozzle water supply ports, respectively; and
a pair of second insertion conduits that protrude from the outer circumferential surface of the gasket, that are located at the second side with respect to the vertical line, and that are configured to receive the pair of second nozzle water supply ports, respectively.

7. The laundry treating apparatus of claim 1 ,
wherein the first connection port protrudes from the first conduit portion in a direction away from the gasket and defines an inlet that is configured to communicate with the first circulation conduit.

8. The laundry treating apparatus of claim 7 , wherein the pump is disposed below the tub, and
wherein the first connection port is located lower than the pair of first nozzle water supply ports.

9. The laundry treating apparatus of claim 8 , wherein the first nozzle water supply conduit defines a flow path having an inner cross-sectional area that decreases from a lower side of the flow path toward an upper side of the flow path.

10. The laundry treating apparatus of claim 8 , wherein the first connection port extends downward.

11. The laundry treating apparatus of claim 10 , wherein the first conduit portion has a lower part extending from a lower end of the first conduit portion in a direction away from the vertical line passing through a center of the gasket, and
wherein the first connection port protrudes from the lower part of the first conduit portion.

12. The laundry treating apparatus of claim 8 , further comprising:
an upper balancing weight configured to couple to the tub and located at an upper side of the gasket,
wherein the first conduit portion has an upper part that defines an upper end of the first conduit portion and from which one of the pair of first nozzle water supply ports protrude, and
wherein the upper part of the first conduit portion is located between the gasket and the upper balancing weight.

13. The laundry treating apparatus of claim 1 , wherein the outer circumferential surface of the gasket defines:
a first seating groove configured to accommodate at least a part of the first conduit portion.

14. The laundry treating apparatus of claim 1 , wherein the gasket comprises:
a pair of first insertion conduits that protrude from the outer circumferential surface of the gasket, that are located at the first side with respect to the vertical line, and that are configured to receive the pair of first nozzle water supply ports, respectively.

15. The laundry treating apparatus of claim 1 , further comprising:
a first upper balancing weight configured to couple to the tub and located at an upper side of the gasket, the first upper balancing weight being located at the first side with respect to the vertical line, and
wherein an upper end of the first nozzle water supply conduit is configured to be positioned between the first upper balancing weight and the gasket.

16. The laundry treating apparatus of claim 15 , further comprising:
a lower balancing weight configured to couple to the tub and located at a lower side of the gasket, the lower balancing weight extending to each of a first side and a second side with respec
