Refrigerant may be circulated in the partitioned plurality of spaces to cool the ice-making member, thereby increasing the contact time between the refrigerant and the ice-making member, and sufficiently exhibiting the cooling capacity of the refrigerant. ## Claims ### Claim 1 An ice-making evaporator, comprising: a main body configured to include a first space extending in a first direction to allow refrigerant to flow; a first wall extending in the first direction and configured to partition the first space into a second space and a third space; an ice-maker extending in a second direction different from the first direction and configured to include a fourth space that is in fluid communication with the first space; a second wall extending in the second direction and configured to divide the fourth space into a fifth space in fluid communication with the second space and a sixth space in fluid communication with the third space; a first path connected to the second space and configured to make the refrigerant flow into the second space; and a second path connected to the third space and configured to make the refrigerant flowing in the third space flow out, wherein a seventh space for allowing the refrigerant to flow from the second space to the third space is provided in the main body, and wherein a partition is provided between the first space and the seventh space to divide the first space and the seventh space and includes a first hole connecting the second space and the seventh space so that the second space and the seventh space are in fluid communication, and a second hole connecting the third space and the seventh space so that the third space and the seventh space are in fluid communication. ### Claim 2 (depends on 1) The ice-making evaporator of claim 1, wherein the partition comprises: a body configured to partition the first space and the seventh space, wherein the first hole and the second hole are formed; and an extension extending from a circumference of the body toward the seventh space and configured to have an outer surface in contact with an inner wall of the main body. ### Claim 3 (depends on 1) The ice-making evaporator of claim 1, wherein a third hole in fluid communication with the first space is formed in the main body, and wherein the ice-maker is coupled to the third hole. ### Claim 4 (depends on 1) The ice-making evaporator of claim 1, wherein the ice-maker comprises a ice-making part in a cylindrical shape and a bottom part provided at an end of the ice-making part to close an end of the fourth space, wherein the bottom part is convex outward. ### Claim 5 (depends on 1) The ice-making evaporator of claim 1, wherein the ice-maker extends in a direction perpendicular to the first direction. ### Claim 6 (depends on 1) The ice-making evaporator of claim 1, wherein the first wall and the second wall are configured to be arranged in parallel on the same plane. ### Claim 7 (depends on 1) The ice-making evaporator of claim 1, further comprising: a third wall coupled to the first wall, wherein the third wall comprises a first guide part disposed in the second space to guide the refrigerant flowing from a first end to a second end of the second space to pass through the fifth space. ### Claim 8 (depends on 7) The ice-making evaporator of claim 7, wherein the third wall and the first wall are configured to be arranged perpendicular to each other. ### Claim 9 (depends on 7) The ice-making evaporator of claim 7, wherein the third wall further comprises: a second guide part disposed in the third space to guide the refrigerant flowing from a first end to a second end of the third space to pass through the sixth space. ### Claim 10 (depends on 7) The ice-making evaporator of claim 7, wherein the third wall further comprises: a third guide part disposed in the fourth space to partition the fifth space into a eighth space and a ninth space. ### Claim 11 (depends on 10) The ice-making evaporator of claim 10, wherein the third guide part is configured to extend along the fourth space to guide the refrigerant flowing in the fifth space in the second direction. ### Claim 12 (depends on 10) The ice-making evaporator of claim 10, wherein a fourth hole configured to connect the eighth space and the ninth space to be fluidly communicated is formed in the third guide part. ### Claim 13 (depends on 12) The ice-making evaporator of claim 12, wherein the fourth hole is located biased toward an end of the ice-maker. ### Claim 14 (depends on 7) The ice-making evaporator of claim 7, wherein a first groove to which the third wall is coupled is formed at a side of the first wall in the first direction, and wherein a second groove configured to be correspondingly coupled to the first groove is formed at a first end of the third wall toward the first space. ### Claim 15 (depends on 7) The ice-making evaporator of claim 7, wherein the second wall is coupled to the third wall. ### Claim 16 (depends on 15) The ice-making evaporator of claim 15, wherein a third groove to which the third wall is coupled is formed at an end of the second wall toward the first space, and wherein a fourth groove configured to be correspondingly coupled to the third groove is formed at a second end of the third wall. ### Claim 17 (depends on 1) The ice-making evaporator of claim 1, wherein the second and third spaces extend parallel to each other, and wherein the seventh space is located at an end of the first space. ### Claim 18 (depends on 1) The ice-making evaporator of claim 1, further comprising: a third path connected to the second space and configured to make heated gas flow into the second space. ### Claim 19 (depends on 1) The ice-making evaporator of claim 1, wherein the ice-maker is provided in plurality, and wherein the plurality of ice-makers are configured to be arranged along the first direction.
