Abstract

Provided is a liquid dispensing device. The liquid dispensing device includes a cylinder body coupled to a sink and at least one nozzle coupled to the cylinder body. The at least one nozzle may include a first liquid discharge nozzle coupled to an upper region of the cylinder body to extend horizontally, the first liquid discharge nozzle being configured to supply a drinkable liquid, such as a purified liquid, a heated liquid, or a cooled liquid. The at least one nozzle may a second liquid discharge nozzle coupled to the cylinder body to extend horizontally, the second liquid discharge nozzle being positioned to be spaced apart from the first liquid discharge nozzle to supply a non-drinkable liquid, such as a sterilizing liquid containing hypochlorous acid or other additive.

First claim

What is claimed is:

1. A liquid dispenser provided at a sink and comprising:
a cylinder body coupled to the sink;
a first liquid discharge nozzle coupled to the cylinder body, the first liquid discharge nozzle supplying at least one of a purified liquid, a heated liquid, or a cooled liquid; and
a second liquid discharge nozzle coupled to the cylinder body the second liquid discharge nozzle being spaced from the first liquid discharge nozzle and supplying a sterilizing liquid,
wherein the liquid dispenser further comprises a touch screen positioned at an upper surface of the first liquid discharge nozzle, and
wherein the touch screen controls each of a hot, purified, cold, sterilized liquid selection function, a liquid discharge command function, a cold and hot liquid temperature setting and display function, a filter replacement cycle notification function, a function of setting capacity of liquid discharged, and a function of setting a discharge time of the liquid discharged.

2. The liquid dispenser of claim 1 ,
wherein the first liquid discharge nozzle and the second liquid discharge nozzle rotate independently with respect to the cylinder body.

3. The liquid dispenser according to claim 2 , wherein a first insertion extension having a hollow shape into which an upper end of the cylinder body is accommodated is defined in a lower end of one side of the first liquid discharge nozzle, and
a second insertion extension having a hollow shape through which a portion of the cylinder body passes is defined in a lower end of one side of the second liquid discharge nozzle.

4. The liquid dispenser according to claim 3 , wherein a first body having a hollow shape and defining an outer appearance to cover the second insertion extension and a section of the cylinder body is positioned between an outer surface of the sink and the second liquid discharge nozzle, and
a second body having a hollow shape and defining an outer appearance to cover the first insertion extension and a section of the cylinder body is positioned between the first liquid discharge nozzle and the second liquid discharge nozzle.

5. The liquid dispenser according to claim 4 , wherein at least one O-ring or square ring, which is made of an elastic material to hold a clearance, is inserted at least one of between the cylinder body and the first insertion extension or between the cylinder body and the second insertion extension.

6. The liquid dispenser according to claim 4 , wherein at least one O-ring or square ring, which is made of an elastic material to hold a clearance, is inserted at one of between the first insertion extension and the second body or between the second insertion extension and the first body.

7. The liquid dispenser according to claim 4 , wherein a square ring insertion groove that is recessed inward is defined in an outer surface of the cylinder body in a circumferential direction,
an insertion section of a square ring support is inserted into the square ring insertion groove, and the square ring insertion groove further includes a square ring support extending horizontally from a lower end of the insertion section to an outside, and
a second square ring is seated on an upper end of the square ring support.

8. The liquid dispenser according to claim 7 , wherein an upper end of the second square ring is in contact with and supported on a lower end of the second insertion extension.

9. The liquid dispenser of claim 1 , wherein:
the cylinder body includes a hollow and a rotation limit hole opened by a predetermined height that is defined along a circumference of a side surface thereof,
the second liquid discharge nozzle has one side at which an insertion extension having a cylindrical shape and rotatably connected to the cylinder body is defined and another side at which a cock connected to a tube extending into the hollow of the cylinder body and the rotation limit hole is positioned, the second liquid discharge nozzle being provided with a second stopper accommodated in the rotation limit hole at one side thereof to limit a rotation range of the second liquid discharge nozzle.

10. The liquid dispenser according to claim 9 , wherein at least a portion of the stopper protrudes inside of the insertion extension.

11. The liquid dispenser according to claim 9 , wherein the insertion extension is a second insertion extension, the tube is a second tube, and the cock is a second cock, and
wherein the first liquid discharge nozzle has one side at which a first insertion extension having a cylindrical shape is defined and another side at which a first cock connected to a first tube extending into the hollow of the cylinder body and an upper end of the cylinder body is positioned.

12. The liquid dispenser according to claim 11 , wherein a first connection member having a ring shape is coupled to an upper end of the cylinder body, and a pair of stoppers protrude upward from respective sides of an upper end of the first connection member, wherein the pair of stoppers include a first stopper and a third stopper, and
wherein at least a portion of the first stopper extends to an upper side of the first connection member to limit a rotation range of the first liquid discharge nozzle while being hung on the first stopper when the first liquid discharge nozzle rotates.

13. The liquid dispenser according to claim 12 , wherein the first stopper extends to protrude inside of the first insertion extension.

14. The liquid dispenser according to claim 12 , further comprising a second connection member which is positioned below the first connection member, at least a portion of the second connection member being inserted into and coupled to the hollow of the cylinder body.

15. The liquid dispenser according to claim 14 , further comprising a coupling member configured to connect the first connection member to the second connection member, the coupling member extending upward to partition the hollow of the cylinder body into a plurality of spaces.

16. The liquid dispenser of claim 1 , wherein:
the first liquid discharge nozzle has a first side coupled to an upper section of the cylinder body to extend horizontally and a second side at which a first cock connected to a first tube passing through the first liquid discharge nozzle and into a hollow section of the cylinder body is positioned, the first liquid discharge nozzle having an upper region that is opened, and
the touch screen is separably coupled to the upper region of the first liquid discharge nozzle, the touch screen covering the opened upper region of the first liquid discharge nozzle when coupled to the first liquid discharge nozzle.

17. The liquid dispenser according to claim 16 , wherein the touch screen includes:
a plate positioned at an uppermost side to define a top surface of the first liquid discharge nozzle;
a frame positioned below the plate to provide a plurality of opening grooves and a sidewall extending downward along a circumference thereof; and
a printed circuit board (PCB) positioned below the frame or positioned inside the frame.

18. The liquid dispenser according to claim 17 , wherein an outer circumference of the plate protrudes further outward than the sidewall of the frame.
