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 that defines a channel extending between the input port of the cabinet and the tub opening;
a plurality of first nozzles located at an inner circumference of the gasket, configured to spray water into the drum, and arranged at a first side with respect to a vertical line passing through a center of the gasket, the plurality of first nozzles including a first upper nozzle disposed above a horizontal line passing through a center of the gasket and a first lower nozzle disposed below the horizontal line;
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;
a first circulation conduit connected to the first circulation port of the pump;
a first conduit portion that is located at the first side with respect to the vertical line and that extends along an outer circumference of the gasket;
a first connection port provided at the first conduit portion and connected to the first circulation conduit; and
a plurality of first nozzle water supply ports that protrude from the first conduit portion, that are coupled to the gasket, and that are connected to the plurality of first nozzles,
wherein the plurality of first nozzle water supply ports includes:
a first upper nozzle water supply port connected to the first upper nozzle, and
a first lower nozzle water supply port connected to the first lower nozzle.

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

3. The laundry treating apparatus of claim 2 , further comprising:
a lower balancing weight coupled 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 , further comprising:
a first upper balancing weight coupled 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 positioned between the first upper balancing weight and the gasket.

5. The laundry treating apparatus of claim 4 , further comprising:
a lower balancing weight coupled 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, and
wherein the first connection port is disposed between the first upper balancing weight and the lower balancing weight.

6. The laundry treating apparatus of claim 2 , wherein the gasket further comprises an upper nozzle located at the inner circumference of the gasket and configured to spray water into the drum, the upper nozzle being positioned above the plurality of first nozzles, and
wherein the first nozzle water supply conduit further comprises an upper nozzle water supply port that protrudes from the first conduit portion toward the gasket, that is coupled to the gasket, and that is connected to the upper nozzle.

7. The laundry treating apparatus of claim 2 , 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.

8. 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.

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

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

11. 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.

12. The laundry treating apparatus of claim 11 , wherein the pump is disposed below the tub, and
wherein the first connection port is located lower than the plurality of first nozzle water supply ports.

13. The laundry treating apparatus of claim 12 , wherein the first connection port extends downward.

14. The laundry treating apparatus of claim 12 , further comprising:
an upper balancing weight coupled 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 plurality 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.

15. The laundry treating apparatu
