Running-water-type evaporator, and ice-making device and water purification device comprising same

1 . A running-water-type evaporator, comprising:

a pair of outer plate members that are disposed to face each other; and

a flow plate member which is disposed between the pair of outer plate members to partition a space between the pair of outer plate members so as to form a first flow path through which a low-temperature fluid for generating ice or a high-temperature fluid for separating the generated ice flows,

wherein each outer plate member of the pair of outer plate members comprises a heat transfer surface which is formed on an inside of each plate of the pair of outer plate members to thermally contact the low temperature or high temperature fluid, an ice generating surface which is formed on an outside of each plate of the pair of outer plate members such that a first surface of ice is formed to be attached to the outside of each plate of the pair of outer plate members, a partition wall which protrudes outward to partition the ice generating surface such that a second surface of the ice which is formed to extend from the first surface of ice is attached to the partition wall and extends in a direction crossing the flow direction of the low temperature or high temperature fluid flowing through the first flow path, and a supply groove which protrudes outward to form a second flow path that communicates with an inside of the partition wall such that the high-temperature fluid is supplied to the inside of the partition wall.

2 . The running-water-type evaporator of claim 1 , further comprising:

an inner plate member which is disposed to be bonded to the heat transfer surface so as to prevent the low temperature or high temperature fluid flowing inside the supply groove and the partition wall from leaking into a space between the pair of outer plate members.

3 . The running-water-type evaporator of claim 1 , wherein the partition wall is formed to extend in parallel with a direction in which ice-making water flows,

wherein the partition wall is a plurality of the partition walls that are disposed to be spaced apart from each other at regular intervals, and

wherein at least one outer plate member of the pair of outer plate members further comprises a connection groove such that the partition walls that are disposed to be adjacent to each other communicate with each other, and a discharge groove through which the low temperature or high temperature fluid flowing inside the plurality of partition walls is discharged.

4 . The running-water-type evaporator of claim 3 , wherein the supply groove is in communication with at least one of the plurality of partition walls to supply the high-temperature fluid to the inside of the partition wall, and

wherein the high-temperature fluid supplied to the partition wall is discharged through the discharge groove after moving to another partition wall of the plurality of partition walls that is disposed to be adjacent to the partition wall through the connection groove.

5 . The running-water-type evaporator of claim 2 , wherein the flow plate member is a pair of flow plate members and are each provided so as to face each other, and

wherein each of the flow plate members of the pair of flow plate members comprises a main groove that protrudes outward.

6 . The running-water-type evaporator of claim 5 , wherein the pair of flow plate members each comprises a first opening hole that is formed to penetrate such that the low temperature or high temperature fluid flows through the main groove and directly contacts the heat transfer surface.

7 . The running-water-type evaporator of claim 6 , wherein the inner plate member comprises a second opening hole that is formed to penetrate such that the low temperature or high temperature fluid passes through the first opening hole and directly contacts the heat transfer surface.

8 . The running-water-type evaporator of claim 7 , wherein each of the pair of flow plate members comprises a heat transfer column that protrudes outward along the main groove and makes surface contact with the heat transfer surface, and

wherein the first opening hole is provided at a front end of the heat transfer column.

9 . The running-water-type evaporator of claim 8 , wherein a support surface which supports an outer side surface of the heat transfer column in a state where the heat transfer column is inserted is provided around the periphery of the second opening hole.

10 . The running-water-type evaporator of claim 2 , wherein the supply groove comprises a plurality of supply grooves and the pair of outer plate members are each provided with one of the plurality the supply grooves, respectively, and

wherein the inner plate member is disposed to be bonded to each of the pair of outer plate members.

11 . The running-water-type evaporator of claim 2 , wherein the flow plate member comprises a pair of flow plate members, and

wherein among the pair of flow plate members, any one of the flow plate members comprises a coupling piece that is coupled to the other flow plate member.

12 . The running-water-type evaporator of claim 2 , wherein the flow plate member comprises a pair of flow plate members, and

wherein among the pair of flow plate members, any one of the flow plate members comprises a support piece that is supported in contact with the inner plate member.

13 . The running-water-type evaporator of claim 12 , wherein the inner plate member comprises a counter piece that is supported in contact with the support piece.

14 . The running-water-type evaporator of claim 1 , wherein bonding surfaces that are capable of mutual bonding are provided around a periphery of the pair of outer plate members, respectively.

15 . The running-water-type evaporator of claim 14 , wherein bent surfaces that are bent inward are provided around the periphery of the pair of outer plate members that are disposed to face each other, and

wherein the bonding surfaces are provided at a front end of the bent surface.
