Abstract

A washing machine including: a cabinet; a tub mounted inside the cabinet to receive washing water; a rotating drum mounted inside the tub to load laundry therein; and an injection unit to inject washing water inside of the rotating drum. The injection unit includes: a plurality of nozzles spaced away from each other to inject washing water inside of the rotating drum at different positions; and a connector configured to include a plurality of passages so that a flow path of washing water diverges into the plurality of nozzles. Washing water may be injected by the spaced nozzles over a wide area inside the drum.

First claim

What is claimed is:

1. A washing machine comprising:
a cabinet;
a tub mounted inside the cabinet to contain washing water, the tub having an upper portion;
a drum mounted inside the tub to receive laundry and to be rotatable, the drum having an open upper portion;
a pump configured to supply washing water;
a plurality of nozzles spaced away from each other on the upper portion of the tub to inject washing water to an inside of the drum via the upper open portion of the drum;
a connector at the upper portion of the tub and having an inlet and two outlets defining a plurality of passages through which washing water flows to the plurality of nozzles;
a first hose extending along a side wall of the tub, a first end of which is connected to the pump and a second end of which is connected to the inlet of the connector to direct washing water from the pump to the connector, wherein the first outlet of the connector communicates with a first one of the plurality of nozzles;
a second hose extending in a circumferential direction of the upper portion of the tub, a first end of which is connected to the second outlet of the connector and a second end of which is connected to a second one of the plurality of nozzles;
a groove that extends along a circumference of the upper portion of the tub to support at least a portion of the second hose;
a lower rib defining a bottom of the groove;
a plurality of side ribs defining a side wall of the groove and corresponding to a surface of the second hose facing an outside of the tub; and
a plurality of upper ribs defining an upper wall of the groove and arranged alternately with the plurality of side ribs.

2. The washing machine according to claim 1 , wherein:
the second outlet is in alignment with the inlet along a central axis of the connector, and the first outlet is angled relative to the central axis of the connector, and
the inlet, the first outlet, the second outlet, the first nozzle and the second nozzle are in continuous washing water communication with each other.

3. The washing machine according to claim 2 , wherein a diameter of the first outlet is greater than a diameter of the second outlet.

4. A washing machine comprising:
a cabinet;
a tub mounted inside the cabinet and having an opening on a top side of the tub;
a drum mounted inside the tub to receive laundry and to be rotatable, the drum having an upper opening;
a pump configured to supply washing water;
a fixing unit coupled on the top side of the tub at the opening of the tub;
a first nozzle and a second nozzle disposed at the fixing unit to inject washing water through the opening of the drum and to the inside of the drum;
a connector at the upper position of the tub, and having an inlet, a first outlet, and a second outlet;
a first hose extending along a side wall of the tub, a first end of which is connected to the pump and a second end of which is connected to the inlet of the connector to direct washing water from the pump to the connector,
wherein the first outlet of the connector communicates with a first one of the plurality of nozzles;
a second hose extending in a circumferential direction of the upper portion of the tub, a first end of which connects to the second outlet, and a second end of which connects to a second one of the plurality of nozzles; and
a groove that extends along a circumference of the top side of the tub to support at least a portion of the second hose,
wherein the fixing unit comprises:
a lower rib defining a bottom of the groove;
a plurality of side ribs defining a side wall of the groove and corresponding to a surface of the second hose facing an outside of the tub; and
a plurality of upper ribs defining an upper wall of the groove and arranged alternately with the plurality of side ribs.

5. The washing machine according to claim 4 , wherein a diameter of the first outlet is greater than a diameter of the second outlet.

6. The washing machine according to claim 5 , wherein the second outlet is in alignment with the inlet along an axis of the connector.
