Abstract

A cup washer includes a tub providing a space in which a cup is accommodated, and a sprayer disposed on the tub and configured to spray water toward the cup. The sprayer includes a first spray nozzle and a second spray nozzle coupled to the first spray nozzle. The second spray nozzle is disposed on a central portion of the first spray nozzle. The first spray nozzle extends away from an outer circumference of the second spray nozzle. The first spray nozzle is rotatable around the second spray nozzle.

First claim

What is claimed is:

1 . A cup washer comprising:
a tub having a space configured to accommodate a cup therein; and a sprayer located at the tub, the sprayer being configured to spray water toward the cup, the sprayer including:
a first spray nozzle; and
a second spray nozzle extending in a vertical direction, the second spray nozzle including at least one spray hole,
wherein the first spray nozzle extends away from an outer circumference of the second spray nozzle toward opposite side surfaces of the tub, the first spray nozzle being configured to rotate around the second spray nozzle, the first spray nozzle including at least one spray hole.

2 . The cup washer of claim 1 , wherein the sprayer includes:
a first bracket, the first spray nozzle being rotatably coupled to the first bracket; and a second bracket coupled to a lower portion of the tub to mount the sprayer on the tub, the second spray nozzle being fixedly coupled to the second bracket, and wherein the first bracket is coupled to the second bracket.

3 . The cup washer of claim 2 , wherein the first spray nozzle includes:
a first piece defining an upper portion of the first spray nozzle; and a second piece defining a lower portion of the first piece, the second piece being coupled to the first piece to define a space in which a first portion of the water flows.

4 . The cup washer of claim 3 , wherein the first spray nozzle includes a connector protruding downward from the second piece, the connector surrounding at least a portion of the second spray nozzle, the connector being configured to define a flow path along which a first portion of the water flows into the first spray nozzle, and
wherein the first bracket includes:
a first coupler having a hole into which the connector is inserted, the first coupler surrounding the connector; and
a second coupler extending in a diametrical direction of the first coupler, the second coupler being coupled to the second bracket.

5 . The cup washer of claim 4 , wherein a central portion of the first piece of the first spray nozzle includes a first insertion hole configured to receive the second spray nozzle,
wherein the first piece includes a stopper surrounding the first insertion hole, the stopper protruding upward, and wherein the second spray nozzle includes a stepped surface opposite the stopper.

6 . The cup washer of claim 5 , wherein the second bracket includes:
a first body coupled to the second spray nozzle, the first body defining a flow path along which a second portion of the water flows into the second nozzle; a second body extending in a diametrical direction of the first body, the second body being coupled to the tub; and a third body connecting the first body to the second body, the third body having a first through hole in communication with the connector of the first spray nozzle, and wherein the tub includes:
a second insertion hole in communication with the first through hole, the first body of the second bracket being received in the second insertion hole; and
a first mounting member surrounding the second insertion hole, the first mounting member protruding upward, the second body being coupled to the first mounting member.

7 . The cup washer of claim 1 , wherein the at least one spray hole of the first spray nozzle includes a plurality of first spray holes located in an upper surface thereof the first spray holes being spaced apart from each other at positions outward from a rotation center of the first spray nozzle, the first spray holes being configured such that water discharge directions of the first spray holes are inclined with respect to the upper surface.

8 . The cup washer of claim 7 , wherein the at least one spray hole of the first spray nozzle includes a plurality of second spray holes located in a lower surface thereof, the second spray holes being spaced apart from each other at positions outward from the rotation center thereof, the second spray holes being disposed such that water discharge directions of the second spray holes are positioned in opposite directions based on the rotation center of the first spray nozzle.

9 . The cup washer of claim 1 , wherein the second spray nozzle extends beyond an upper surface of the first spray nozzle.

10 . The cup washer of claim 1 , wherein the second spray nozzle includes:
a first protruding portion protruding upward from the first spray nozzle; and a second protruding portion coupled to the first protruding portion, the second protruding portion protruding upward from the first protrusion, and wherein the at least one spray hole of the second nozzle includes:
a plurality of third spray holes spaced apart from each other in a circumferential direction in the first protruding portion; and
at least one fourth spray hole in an upper end portion of the second protruding portion.

11 . The cup washer of claim 10 , wherein the second spray nozzle includes an upper cover at an upper end of the second protruding portion, and
wherein the at least one fourth spray hole includes:
a plurality of first sub spray holes spaced apart from each other in a circumferential direction of a sidewall of the second protrusion; and
a plurality of second sub spray holes spaced apart from each other in a diameter direction and a circumferential direction of the upper cover.

12 . The cup washer of claim 1 , wherein the second spray nozzle extends through a central portion of the first spray nozzle,
wherein the first spray nozzle is connected to a first flow path to allow a first portion of the water to flow therethrough, and wherein the second spray nozzle is connected to a second flow path to allow a second portion of the water to flow therethrough, the second flow path being separate from the first flow path.

13 . The cup washer of claim 12 , wherein the first flow path is defined between an outer surface of the second spray nozzle and an inner surface of the first spray nozzle such that the first flow path surrounds the second flow path.

14 . The cup washer of claim 12 , further comprising a rack inside the tub, the rack being configured to support the cup,
wherein at least a portion of the second spray nozzle extends through a lower end of the rack.

15 . The cup washer of claim 14 , wherein, when the cup is seated on the rack, at least portions of opposite end portions of the first spray nozzle are disposed outside the cup, and at least a portion of the second spray nozzle is disposed inside the cup.

16 . The cup washer of claim 15 , wherein the at least one spray hole of the second spray nozzle includes a plurality of spray holes, and
wherein, when the cup is seated on the rack, at least some of the plurality of spray holes of the second nozzle are located inside the cup.

17 . A cup washer comprising:
a tub having a space configured to accommodate a cup therein; and a sprayer located at the tub, the sprayer being configured to spray water toward the cup, the sprayer including:
a second spray nozzle extending in a vertical direction, the second spray nozzle including at least one spray hole;
a first spray nozzle extending away from an outer circumference of the second spray nozzle toward opposite side surfaces of the tub, the first spray nozzle being configured to rotate around the second spray nozzle, the first spray nozzle including at least one spray hole;
a first flow path defined between the outer circumference of the second spray nozzle and the first spray nozzle; and
a second flow path defined in an internal space of the secon
