Abstract

There is provided a sink including: a washing case that is divided into a plurality of spaces including a dishwashing space; a table on which the washing case is mounted; a dish rack that is detachably provided in the dishwashing space and having a washing nozzle rotatably installed on a bottom; a sump assembly that is mounted on a bottom surface of the dishwashing space and stores washing water to be supplied to the washing nozzle in a state where the dish rack is mounted on the dishwashing space; and a washing cover that slides horizontally above the dishwashing space to be inserted into the table or to cover an opened upper surface of the dishwashing space, in which the washing cover includes an operation unit for inputting operating command for dishwashing and a display unit for displaying various information.

First claim

What is claimed is:

1. A sink comprising:
a washing case that comprises a dishwashing space;
a table configured to receive the washing case;
a dish rack detachably coupled to the washing case and located in the dishwashing space, the dish rack including a washing nozzle located at a lower portion of the dish rack and configured to rotate about an axis;
a sump assembly that is located vertically below the dishwashing space, that is configured to store washing water, and that is configured to supply washing water to the washing nozzle in a state in which the dish rack is located in the dishwashing space; and
a washing cover that is located vertically above the dishwashing space, that is configured to slide in a horizontal direction to cover at least a portion of the dishwashing space, and that is configured to insert into the table to expose at least the portion of the dishwashing space,
wherein the washing cover includes:
an operation unit configured to receive input to control a dishwashing operation in the dishwashing space, and
a display unit configured to display information.

2. The sink according to claim 1 , wherein the sump assembly comprises:
a sump housing located vertically below the dishwashing space and configured to store washing water, the sump housing defining a sump space;
a sump cover that covers at least a portion of an upper surface of the sump housing;
a washing pump located vertically below the sump cover in the sump space and configured to supply water to the washing nozzle;
a washing motor located at a bottom surface of the sump housing and configured to drive the washing pump;
a drain pump located at the bottom surface of the sump housing; and
a drain motor located at the bottom surface of the sump housing and configured to drive the drain pump.

3. The sink according to claim 2 , wherein the washing motor includes a motor shaft configured to connect to the washing pump through the sump housing,
wherein the washing pump includes:
a pump housing located in the sump space, the pump housing including an end that is coupled to the sump cover, and a bottom surface that defines a washing water suction hole configured to receive washing water, and
an impeller located within the pump housing, and
wherein the motor shaft is configured to connect to the impeller through the washing water suction hole.

4. The sink according to claim 3 , further comprising:
a filter located vertically below the washing water suction hole; and
a disposer located vertically below the filter and connected to the motor shaft, the disposer being configured to rotate based on rotation of the motor shaft.

5. The sink according to claim 2 , further comprising a heater located in the sump housing and configured to heat washing water.

6. The sink according to claim 2 , further comprising:
a drain pipe connected to the drain pump and configured to discharge washing water from the sump housing, and
a food waste processor connected to the drain pipe and configured to receive food waste from washing water through the drain pipe.

7. The sink according to claim 6 , wherein the washing case defines a plurality of spaces including the dishwashing space, and
wherein the food waste processor is connected to the plurality of spaces and is configured to output the food waste to a disposal bag.

8. The sink according to claim 2 , wherein the sump cover includes a mounting sleeve that protrudes upward from a center portion of the sump cover and that is configured to insert into a recess defined at a bottom surface of the dish rack.

9. The sink according to claim 2 , wherein the sump cover defines a plurality of drain holes configured to discharge washing water from the dishwashing space to the sump space defined by the sump housing.

10. The sink according to claim 1 , wherein the washing case includes a rear surface that defines a rear surface of the dishwashing space, a washing water supply hole, a detergent supply hole, and a plurality of air holes.

11. The sink according to claim 10 , further comprising:
a drying fan located at the rear surface of the washing case and configured to provide heat to the dishwashing space; and
a drying heater located at the rear surface of the washing case and configured to generate neat,
wherein the drying fan is configured to blow air to the dishwashing space through the plurality of air holes to supply heat generated by the drying heater.

12. The sink according to claim 10 , further comprising a washing water supply pipe that is connected to the washing water supply hole and that is configured to supply at least one of hot water or cold water to the dishwashing space.

13. The sink according to claim 10 , further comprising:
a detergent supply pipe that is connected to the detergent supply hole and that is configured to supply at least one of detergent or rinse aid to the dishwashing space; and
a detergent supply unit that is connected to the detergent supply pipe and that is configured to provide at least one of detergent or rinse aid to the detergent supply pipe.

14. The sink according to claim 1 , wherein the operation unit is located at an upper surface of the washing cover and is configured to, based on insertion of the washing cover into the table, be covered by the table.

15. The sink according to claim 1 , wherein the washing case defines a plurality of spaces including the dishwashing space,
wherein the dish rack further includes a flange that extends in a lateral direction from, an upper side of the dish rack and that is configured to be gripped by a user, and
wherein the flange defines an air slit configured to discharge air from the dishwashing space to a second space of the plurality of spaces.

16. The sink according to claim 1 , wherein the washing case defines a plurality of spaces including the dishwashing space, and
wherein a depth of the dishwashing space is greater than a depth of a second space of the plurality of spaces adjacent to the dishwashing space.

17. The sink according to claim 1 , wherein the washing case further comprises a partition wall that defines a plurality of spaces including the dishwashing space, and
wherein the partition wall is configured to, based on the washing cover covering the dishwashing space, define a gap between the washing cover and an upper portion of the partition wall to discharge air from the dishwashing space to a second space of the plurality of spaces through the gap.
