The first embodiment of the evaporator 100 for an ice maker according to the present invention may include an evaporator body 200, an ice forming unit 300, and an ice separation unit 400.

In the evaporator body 200, a refrigerant passage R is formed as shown in FIG. 3, and the refrigerant can flow as shown in FIG. 5.

A connection pipe (T) communicating with the refrigerant flow path (R) may be connected to one side and the other side of the evaporator body 200, respectively. To this end, for example, as shown in Figure 2, one open side and the other side of the evaporator body 200 can be blocked by a blocking member (CL) formed with a pipe connection hole (HI) to which the connection pipe (T) is connected, respectively. there is.

The connection pipe (T) connected to one side of the evaporator body 200 is connected to the expansion valve or capillary tube (not shown) of the refrigeration cycle, and the connection pipe (T) connected to the other side is connected to the compressor (not shown) of the refrigeration cycle. ) can be connected to. Accordingly, the refrigerant may flow from the expansion valve or capillary tube of the refrigeration cycle to the evaporator body 200 and flow into the refrigerant flow path (R) of the evaporator body 200. Additionally, the refrigerant flowing into the refrigerant passage (R) of the evaporator body 200 may flow through the refrigerant passage (R) and then flow to the compressor of the refrigeration cycle, as shown in FIG. 5 .

The evaporator body 200 may have a U-shaped tubular shape as shown in FIGS. 1 and 2. However, the shape of the evaporator body 200 is not particularly limited, and any shape is possible as long as the refrigerant passage R through which the refrigerant flows can be formed.

An insertion hole (H) may be formed in the evaporator body 200. For example, as shown in Figure 2, not only the above-described pipe connection hole (HT) but also an insertion hole (H) may be formed in the above-described blocking member (CL) that blocks the open one side and the other side of the evaporator body 200, respectively. You can. At least a portion of the ice removal unit 400 may be inserted into the refrigerant passage R of the evaporator body 200 through the insertion hole H.

A member connection hole (HC) may be formed in the evaporator body 200 as shown in FIGS. 3 and 4. An immersion member 310, which will be described later, included in the ice forming unit 300 may be connected to the evaporator body 200 through the member connection hole HC.

The evaporator body 200 may be made of a thermally conductive material. For example, the evaporator body 200 may be made of metal such as stainless steel. However, the material forming the evaporator body 200 is not particularly limited, and may be made of any known material as long as it can form the refrigerant passage R.

The ice forming unit 300 may be connected to the evaporator body 200. Additionally, ice (I) may be formed when water comes into contact with at least a portion of the ice forming unit 300 while the refrigerant below the freezing point flows in the refrigerant passage (R) of the evaporator body 200.

The ice forming unit 300 may include, for example, an immersion member 310. The immersion member 310 may be connected to the evaporator body 200. The immersion member 310 may be connected to the evaporator body 200 by being welded to the evaporator body 200 with one end inserted into the member connection hole HC formed in the evaporator body 200. However, the configuration in which the immersion member 310 is connected to the evaporator body 200 is not particularly limited, and any known configuration, such as connection by fitting or adhesive, is possible.

At least a portion of the immersion member 310 may be submerged in water. For example, as shown in Figure 5, the immersion member 310 may be at least partially submerged in water contained in the tray member TR. And, in this state, if refrigerant below the freezing point flows in the refrigerant passage (R) of the evaporator body 200, ice (I) may be formed in the immersion member 310.

As shown in FIGS. 2 and 3, a connection space (SC) connected to the refrigerant passage (R) of the evaporator body 200 may be formed in the immersion member 310. Accordingly, as shown in Figure 5, the refrigerant flowing in the refrigerant passage (R) of the evaporator body 200 can flow in the immersion member 310, that is, the connection space (SC) of the immersion member 310. And, as a result, the immersion member 310 is cooled more quickly by the refrigerant below the freezing point, so that ice (I) can be formed more quickly and easily in the immersion member 310.

The immersion member 310 may be provided with a partition member 311. By the partition member 311, the connection space (SC) of the immersion member 310 can be divided into a refrigerant inlet (RI) and a refrigerant outflow path (RO), as shown in FIG. 3. In addition, a communication hole 311a is formed in the partition member 311, so that the refrigerant inlet path (RI) and the refrigerant outlet path (RO) partitioned by the immersion member 310 can communicate with each other.

Accordingly, the refrigerant flowing in the refrigerant passage (R) of the evaporator body 200 may flow into the refrigerant inlet path (RI) of the connection space (SC) of the immersion member 310, as shown in FIG. 5. Additionally, the refrigerant in the refrigerant inlet (RI) may flow into the refrigerant outflow path (RO) in the connection space (SC) of the immersed member 310 through the communication hole (311a) of the immersed member 310. Thereafter, the refrigerant flows out into the refrigerant passage (R) of the evaporator body 200 through the refrigerant outflow path (RO) of the connection space (SC) of the immersion member 310 and flows through the refrigerant passage (R).

Meanwhile, the partition member 311 may pass through the refrigerant passage R of the evaporator body 200 and extend to the evaporator body 200, as shown in FIGS. 3 and 4. As a result, all of the refrigerant flowing in the refrigerant passage (R) of the evaporator body 200 can flow in the connection space (SC) of the immersion member 310.

In this configuration, the partition member 311 can contact the immersion member 310 and the evaporator body 200. Additionally, a passing portion 311b may be formed in the partition member 311. The portion of the ice removal unit 400 inserted into the refrigerant passage (R) of the evaporator body 200 may pass through the passage portion 311b of the partition member 311. Additionally, the ice separation unit 400 may contact the passing portion 311b of the partition member 311.

As a result, during ice removal as shown in FIG. 6, the heat transferred from the ice removal unit 400 inserted into the refrigerant passage (R) of the evaporator main body 200 is transferred to the immersion member 310 through the partition member 311. Since it is easily transferred, the ice (I) can be separated more easily from the immersion member 310.

The immersion member 310 and the partition member 311 may be made of a thermally conductive material. For example, the immersion member 310 and the partition member 311 may be made of metal such as stainless steel. However, the material forming the immersion member 310 and the partition member 311 is not particularly limited, and may be made of any known material as long as it can be connected to the evaporator body 200 or provided in the immersion member 310. You can.

Meanwhile, the configuration of the ice forming unit 300 is not particularly limited, and any known configuration is possible, such as including an ice-making frame (not shown) connected to the evaporator body 200 and through which water is sprayed or flows.

At least a portion of the ice separation unit 400 may be inserted into the refrigerant passage R of the evaporator body 200. For example, the ice removal unit 400 may be inserted into the refrigerant passage R of the evaporator body 200 through the above-described insertion hole H of the evaporator body 200.

Additionally, ice-separating fluid above the freezing point may flow inside the ice-separating unit 400. As a result, heat transfer occurs from the ice-separating fluid flowing through the ice-separating unit 400 to the ice (I), so that the ice (I) formed in the ice-forming unit (300) can be separated from the ice-forming unit (300).

For example, as shown in FIG. 6, when the tray member TR is rotated so as not to interfere with the separation of the ice I, when the ice-separating fluid flows inside the ice-separating unit 400, the heat transferred from the ice-separating fluid As a result, the ice (I) formed on the immersion member 310 of the ice forming unit 300 may be separated from the immersion member 310.

In this way, because the ice (I) is separated from the ice forming unit 300 by the heat transferred from the ice-separating fluid flowing inside the ice-separating unit 400, the refrigerant above the freezing point is introduced into the refrigerant flow path (R) of the evaporator main body 200. ), there is no need for a flow path conversion valve (not shown) to flow. Therefore, noise during separation of ice (I) can be minimized.

As described above, at least a portion of the ice removal unit 400 is inserted into the refrigerant passage (R) of the evaporator body 200 and comes into contact with the refrigerant present in the refrigerant passage (R), so that it is not connected to the evaporator body 200 or the ice forming unit. It is possible to separate the ice (I) formed in the ice forming unit 300 without the immersion member 310 of 300 being heated to a high temperature by the heat transferred from the ice-separating fluid flowing inside the ice-separating unit 400. It can only be heated to that degree.

Accordingly, the resistance to corrosion of the ice maker evaporator 100 may not be reduced.

The ice-separating unit 400 may include an ice-separating fluid flow pipe 410 through which ice-separating fluid flows. The ice-separating fluid flow pipe 410 is not particularly limited, and any well-known pipe through which ice-separating fluid can flow is possible.

At least a portion of the ice-separating fluid flow pipe 410 may be inserted into the refrigerant passage R of the evaporator body 200. For example, the ice-separating fluid flow pipe 410 may be provided by passing through the insertion hole (H) of the evaporator body 200 and inserted into the refrigerant passage (R) of the evaporator body 200.

The ice-separating fluid flow pipe 410 may have a shape corresponding to at least a portion of the evaporator body 200. As a result, at least a portion of the ice-separating fluid flow pipe 410 can be easily inserted into the refrigerant passage R of the evaporator body 200. For example, the ice-separating fluid flow pipe 410 may be U-shaped as shown in FIG. 2. In this case, with the straight ice-separating fluid flow pipe 410 penetrating the straight evaporator body 200 through the insertion hole H of the blocking member CL, the evaporator body 200 and the ice-separating fluid flow pipe ( 410) can be bent together into a U shape.

However, the shape of the ice-separating fluid flow pipe 410 is not particularly limited, and any shape is possible as long as it corresponds to at least a portion of the evaporator body 200.

The ice-separating fluid flow pipe 410 may be made of a thermally conductive material. For example, the ice-separating fluid flow pipe 410 may be made of metal such as stainless steel. However, the material forming the ice-separating fluid flow pipe 410 is not particularly limited, and may be made of any known material as long as it is at least partially inserted into the refrigerant passage (R) of the evaporator body 200 and allows the ice-separating fluid to flow. You can.

The ice-separating unit 400 may further include an ice-separating fluid source 420. The ice-separating fluid source 420 may be connected to the ice-separating fluid flow pipe 410. Additionally, ice-separating fluid may be supplied from the ice-separating fluid supply source 420 to the ice-separating fluid flow pipe 410 .

The ice-separating fluid may be, for example, air. In this case, the ice-separating fluid source 420 may include a blowing fan 421 connected to the ice-separating fluid flow pipe 410.
