Abstract

A cup washer of one embodiment may comprise a washing unit for washing an accommodated cup. The washing unit can comprise: a detergent storage part, which is arranged at one side of a tub and stores detergent; a detergent injection unit coupled to the lower portion of the detergent storage part; a detergent pump, which is connected to the detergent injection unit and pumps the detergent to the tub; a rinse aid storage part, which is arranged at the one side of the tub so as to be separated from the detergent storage part and stores rinse aid; a rinse aid injection unit coupled to the lower portion of the rinse aid storage part; and a rinse aid pump, which is connected to the rinse aid injection unit and pumps the rinse aid to the tub.

First claim

What is claimed is:

1 . A cup washer including a washing unit for washing a cup accommodated therein, wherein the washing unit includes:
a tub having a cup receiving space defined therein, wherein washing water is sprayed into the tub; a detergent storage disposed on one side of the tub and configured to store therein detergent; a detergent injection part coupled to a bottom of the detergent storage; and a detergent pump connected to the detergent injection part and configured to pump the detergent to the tub.

2 . The cup washer of claim 1 , wherein the detergent pump includes:
a first connector connected to the detergent injection part and configured to receive the detergent from the detergent injection part; and a detergent discharge part having one side connected to the first connector and configured to discharge the detergent into the tub.

3 . The cup washer of claim 2 , wherein the detergent discharge part includes:
a detergent pumping part connected to the first connector and configured to receive the detergent from the first connector and pump the received detergent; and a detergent injection nozzle coupled to the detergent pumping part, and connected to the tub, and configured to inject the detergent into the tub.

4 . The cup washer of claim 3 , wherein the washing unit further includes:
a rinse storage disposed on one side of the tub and spaced from the detergent storage and configured to store therein rinse; a rinse injection part coupled to a bottom of the rinse storage; and a rinse pump connected to the rinse injection part and configured to pump the rinse to the tub.

5 . The cup washer of claim 4 , wherein the rinse pump includes:
a second connector connected to the rinse injection part and configured to receive the rinse from the rinse injection part; and a rinse discharge part having one side connected to the second connector and the other side connected to the tub, and configured to discharge the rinse into the tub.

6 . The cup washer of claim 5 , wherein the rinse discharge part includes:
a rinse pumping part connected to the second connector and configured to receive the rinse from the second connector and pump the received rinse; and a rinse injection nozzle coupled to the rinse pumping part, and connected to the tub, and configured to inject the rinse into the tub.

7 . The cup washer of claim 6 , wherein the detergent injection part further includes:
a first lower cover coupled to the bottom of the detergent storage; and a first connection portion protruding downwardly from the first lower cover, and coupled to the first connector, and having a first flow hole defined therein through which the detergent flows, wherein the first lower cover has an upper surface extending in a downwardly inclined manner as the upper surface extends toward the first flow hole.

8 . The cup washer of claim 7 , wherein the rinse injection part further includes:
a second lower cover coupled to the bottom of the rinse storage; and a second connection portion protruding downwardly from the second lower cover, and coupled to the second connector, and having a second flow hole defined therein through which the rinse flows, wherein the second lower cover has an upper surface extending in a downwardly inclined manner as the upper surface extends toward the second flow hole.

9 . The cup washer of claim 6 , wherein the tub includes:
a detergent inlet connected to the detergent injection nozzle through a pipe so as to receive the detergent from the detergent injection nozzle; and a washing water inlet disposed on top of the detergent inlet, wherein water flows into the tub through the washing water inlet.

10 . The cup washer of claim 9 , wherein the cup washer further comprises:
a water storage tank disposed under the washing unit and configured to store therein water; a first connection pipe connecting the washing water inlet and the water storage tank to each other; a second connection pipe connecting the rinse injection nozzle and the first connection pipe to each other; and a three-way fitting fitted with the first connection pipe, wherein one end of the second connection pipe is fitted with the three-way fitting.

11 . The cup washer of claim 10 , wherein the rinse discharged from the rinse injection nozzle flows from the second connection pipe into the first connection pipe and is mixed with water flowing through the first connection pipe, and then, a mixture of the rinse and the water is introduced into the tub.

12 . The cup washer of claim 8 , wherein the washing unit further includes:
a drying module disposed on a side surface of the tub and configured to spray heated air into the tub; a sump disposed under the tub and configured to store therein water sprayed from the tub; a circulation pump disposed under the tub and configured to circulate water between the tub and the sump; and a water discharging pump disposed under the tub and configured to discharge water from the sump to an outside.

13 . The cup washer of claim 12 , wherein the detergent injection part further includes:
a (1-1)-st cover coupling protrusion protruding from the first lower cover and coupled to the tub; a (1-2)-nd cover coupling protrusion protruding from the first lower cover and coupled to the first connector; and a (1-3)-rd cover coupling protrusion protruding from the first lower cover and having a first hook-receiving groove defined therein.

14 . The cup washer of claim 13 , wherein the first connector includes:
a first fastening portion fastened to the (1-2)-nd cover coupling protrusion; and a first coupling hook inserted into the first hook-receiving groove so as to be coupled to the (1-3)-rd cover coupling protrusion.

15 . The cup washer of claim 14 , wherein the detergent pump includes a first body to which the first connector is coupled,
wherein the first body includes a (1-1)-st module fastening portion formed to protrude in a lateral direction and fastened to the drying module, wherein the drying module includes a (1-2)-nd module fastening portion protruding toward the (1-1)-st module fastening portion, wherein the (1-1)-st module fastening portion is fastened to the (1-2)-nd module fastening portion.

16 . The cup washer of claim 12 , wherein the rinse injection part further includes:
a (2-1)-st cover coupling protrusion protruding from the second lower cover and coupled to the tub; a (2-2)-nd cover coupling protrusion protruding from the second lower cover and coupled to the second connector; and A (2-3)-rd cover coupling protrusion protruding from the second lower cover and having a second hook-receiving groove defined therein.

17 . The cup washer of claim 16 , wherein the second connector includes:
a second fastening portion fastened to the (2-2)-nd cover coupling protrusion; and a second coupling hook inserted into the second hook-receiving groove so as to be coupled to the (2-3)-rd cover coupling protrusion.

18 . The cup washer of claim 17 , wherein the rinse pump includes a second body to which the second connector is coupled,
wherein the second body includes a (2-1)-st module fastening portion formed to protrude in a lateral direction and fastened to the drying module, wherein the drying module includes a (2-2)-nd module fastening portion protruding toward the (2-1)-st module fastening portion, wherein the (2-1)-st module fastening portion is fastened to the (2-2)-nd module fastening portion.
