Abstract

The present disclosure relates to a water purifier. A water purifier according to an aspect includes a coolant tank in which a coolant is stored, a cold water pipe accommodated in the coolant tank, an evaporator accommodated in the coolant tank, a stirring member placed inside the coolant tank to stir the coolant, and a partition member accommodated inside the coolant tank to partition an inner space of the coolant tank into a first space and a second space, wherein the evaporator is located in the first space, and the cold water pipe is located in the second space.

First claim

The invention claimed is:

1. A liquid dispenser comprising:
a coolant tank in which a coolant is stored;
a cold water pipe accommodated in the coolant tank;
an evaporator accommodated in the coolant tank;
a stirring member placed inside the coolant tank to stir the coolant; and
a partition member accommodated inside the coolant tank to partition an inner space of the coolant tank into a first space and a second space,
wherein the evaporator is located in the first space, and the cold water pipe is located in the second space, wherein the partition member comprises a bottom part configured to partition the inner space of the coolant tank into the first space and the second space and having a plurality of holes for flow of the coolant, wherein the first space is defined above the bottom part, and the second space is defined below the bottom part, and wherein the stirring member passes through the partition member in the first space to be located in the second space.

2. The liquid dispenser of claim 1 , wherein the bottom part is transversely arranged inside the coolant tank.

3. The liquid dispenser of claim 1 , wherein the bottom part is in contact with an inner circumferential surface of the coolant tank.

4. The liquid dispenser of claim 1 , wherein a through-hole through which the stirring member passes is formed in the bottom part, and
wherein the partition member comprises an extension protruding from an edge of the through-hole toward the first space.

5. The liquid dispenser of claim 4 , wherein the extension comprises:
a plurality of vertical ribs extending upward from an upper surface of the bottom part corresponding to the edge of the through-hole by a predetermined length and spaced apart from each other along a circumference of the through-hole by a specific interval; and
a connection rib connecting the plurality of vertical ribs to each other.

6. The liquid dispenser of claim 4 , wherein the connection rib is formed to have a circular band shape, and
wherein a diameter of the through-hole is equal to or larger than an inner diameter of the connection rib.

7. The liquid dispenser of claim 4 , wherein the evaporator comprises a refrigerant pipe wound outside the extension in a spiral shape.

8. The liquid dispenser of claim 7 , wherein the extension comprises a pipe support rib on which the refrigerant pipe is to be seated.

9. The liquid dispenser of claim 8 , wherein the refrigerant pipe supported on the pipe support rib is spaced apart from an upper surface of the bottom part.

10. The liquid dispenser of claim 1 , wherein the partition member comprises:
a bottom part configured to partition the inner space of the coolant tank into the first space and the second space and having a through-hole therein; and
an extension extending from an edge of the through-hole to the first space.

11. The liquid dispenser of claim 10 , wherein the stirring member extends from the first space to the second space through the extension and the through-hole.

12. The liquid dispenser of claim 10 , wherein the extension comprises:
a plurality of vertical ribs extending upward from an upper surface of the bottom part corresponding to the edge of the through-hole by a predetermined length and spaced apart from each other along a circumference of the through-hole by a specific interval; and
a connection rib connecting the plurality of vertical ribs to each other.

13. The liquid dispenser of claim 1 , wherein the cold water pipe is wound in a spiral shape to have a cylindrical hollow shape, and
wherein the partition member is seated on an upper surface of the cold water pipe.

14. The liquid dispenser of claim 13 , wherein a cold water pipe seating part to which the cold water pipe is seated is provided on a lower surface of the partition member.
