Abstract

A laundry treating apparatus includes a cabinet, a tub, a water supply part, a drum rotatably located in the tub and including a drum floor surface located on an opposite side of a drum opening, a rotator rotatably located on the drum floor surface within the drum, the rotator including a bottom portion located on the drum floor surface, a pillar protruding from the bottom portion toward the drum opening, and a blade provided to an outer circumferential surface of the pillar, and a spray device connected to the water supply part to spray water supplied from the water supply part into the drum through the drum opening by avoiding the pillar and the blade.

First claim

What is claimed is:

1 . A laundry treating apparatus comprising:
a cabinet that defines an exterior of the laundry treating apparatus, the cabinet defining a laundry opening configured to receive laundry therethrough; a tub located within the cabinet, the tub defining a tub opening that is in communication with the laundry opening; a water supply part connected to a water supply source and configured to supply water to the tub; a drum rotatably located in the tub, the drum defining a drum opening that is in communication with the tub opening and faces a drum floor surface located at an opposite side of the drum opening; a rotator rotatably located within the drum, the rotator comprising:
a bottom portion located at the drum floor surface,
a pillar that protrudes from the bottom portion toward the drum opening, and
a blade located at an outer circumferential surface of the pillar; and
a spray device connected to the water supply part and configured to spray the water supplied from the water supply part into the drum through the drum opening in a direction avoiding the pillar and the blade.

2 . The laundry treating apparatus of claim 1 , wherein the spray device is located outside the tub.

3 . The laundry treating apparatus of claim 2 , wherein the cabinet comprises a cabinet top side that defines a top surface thereof and the laundry opening, and
wherein the spray device is located at the cabinet top side.

4 . The laundry treating apparatus of claim 3 , wherein the cabinet top side comprises a laundry opening face that defines an inner circumferential surface of the laundry opening, and
wherein the spray device is located at the laundry opening face.

5 . The laundry treating apparatus of claim 4 , wherein the spray device comprises:
a nozzle supply pipe connected to the water supply part and configured to receive the water from the water supply part; and a nozzle coupled to the nozzle supply pipe and configured to spray the water supplied through the nozzle supply pipe into the drum.

6 . The laundry treating apparatus of claim 4 , wherein the spray device comprises:
a first nozzle configured to spray the water in a first direction; and a second nozzle configured to spray the water in a second direction different from the first direction.

7 . The laundry treating apparatus of claim 6 , wherein the first nozzle is configured to spray the water to a first side with respect to the pillar, and
wherein the second nozzle is configured to spray the water to a second side with respect to the pillar, the second side being different from the first side.

8 . The laundry treating apparatus of claim 6 , wherein the drum has a first drum space and a second drum space that are divided by a virtual plane connecting the spray device and the pillar,
wherein the first nozzle is configured to spray the water toward the first drum space, and wherein the second nozzle is configured to spray the water toward the second drum space.

9 . The laundry treating apparatus of claim 7 , wherein the first nozzle is configured to spray the water toward a circumferential surface of the drum, and
wherein the second nozzle is configured to spray the water toward the drum floor surface.

10 . The laundry treating apparatus of claim 7 , wherein the first nozzle defines a first spray orifice at an end portion thereof, the first spray orifice being configured to discharge the water in the first direction,
wherein the second nozzle defines a second spray orifice at an end portion thereof, the second spray orifice being configured to discharge the water in the second direction, and wherein an area of the first spray orifice is greater than an area of the second spray orifice.

11 . The laundry treating apparatus of claim 10 , wherein the first direction corresponds to a first spray direction of water discharged through a center of the first spray orifice, the first spray direction defining a first angle with respect to a gravity direction,
wherein the second direction corresponds to a second spray direction of water discharged through a center of the second spray orifice, the second spray direction defining a second angle with respect to the gravity direction, and wherein the first angle is greater than the second direction.

12 . The laundry treating apparatus of claim 10 , wherein the first nozzle is configured to discharge a first spray amount of water through the first spray orifice for a reference time,
wherein the second nozzle is configured to discharge a second spray amount of water through the second spray orifice for the reference time, and wherein the first spray amount of water is greater than the second spray amount of water.

13 . The laundry treating apparatus of claim 3 , further comprising a detergent supply device located at the cabinet top side and configured to store a detergent therein, the detergent supply device configured to supply the detergent to the drum or the tub, and
wherein the water supply part is connected to the detergent supply device and the spray device and configured to supply the water into the tub through at least one of the detergent supply device or the spray device.

14 . The laundry treating apparatus of claim 13 , wherein the water supply part comprises:
an external water supply flow path connected to the water supply source and configured to guide the water to an inside of the cabinet; a water supply valve connected to the external water supply flow path and configured to selectively open and close the external water supply flow path; an internal water supply flow path that connects the water supply valve to the detergent supply device and is configured to guide the water to the detergent supply device; and a spray water supply flow path that connects the water supply valve to the spray device and is configured to guide the water to the spray device.

15 . The laundry treating apparatus of claim 14 , wherein the cabinet top side comprises a laundry opening face that defines an inner circumferential surface of the laundry opening, and
wherein the spray device comprises:
a nozzle supply pipe that is connected to the water supply part and penetrates the laundry opening face, the nozzle supply pipe being configured to receive the water through the spray water supply flow path, and
a nozzle coupled to the nozzle supply pipe and configured to spray the water supplied through the nozzle supply pipe into the drum.

16 . The laundry treating apparatus of claim 15 , wherein the laundry opening face defines a detergent supply opening that accommodates the detergent supply device and is in communication with the laundry opening, and
wherein the spray device is located at one side of the detergent supply opening.

17 . The laundry treating apparatus of claim 16 , wherein the spray device and the detergent supply opening are located rearward relative to the pillar.

18 . The laundry treating apparatus of claim 1 , wherein the spray device is located vertically above the drum opening and rearward relative to the pillar.

19 . The laundry treating apparatus of claim 1 , wherein the spray device comprises a plurality of orifices configured to spray the water in a plurality of directions avoiding the pillar and the blade.

20 . The laundry treating apparatus of claim 19 , wherein the plurality of orifices are configured to discharge the water in opposite directions with respect to the pillar.
