The first embodiment of the evaporator 100 for ice making according to the present invention may include an evaporation tube 200, a finger member 300, and a heat transfer obstruction member 400.

A refrigerant flow path RR may be formed in the evaporation tube 200. One side of the refrigerant passage RR is connected to a capillary or expansion valve (not shown) included in the refrigeration cycle (not shown) by a connecting tube (not shown), etc., and the other side of the refrigerant passage RR is connected to a connecting tube, etc. It can be connected to a compressor (not shown) included in the refrigeration cycle. Accordingly, a refrigerant having a temperature lower than the freezing point is introduced from a capillary tube or an expansion valve to one side of the refrigerant flow path RR, flows through the refrigerant flow path RR, and is discharged to the other side of the refrigerant flow path RR to flow to the compressor. .

As described above, the finger member 300 connected to the evaporation tube 200 is immersed in water contained in a drip tray (not shown) or the finger member 300 in a state in which a refrigerant having a temperature lower than the freezing point flows through the refrigerant flow path RR. When water is sprayed on), ice I may be generated on the finger member 300 as illustrated in FIG. 3.

Meanwhile, one side of the refrigerant flow path RR may be connected to the refrigerant discharge side of the compressor, for example, by a defrosting bypass pipe (not shown). Then, by opening the de-icing valve (not shown) provided in the de-icing bypass pipe, a refrigerant having a temperature higher than the freezing point discharged from the refrigerant discharging side of the compressor flows into one side of the refrigerant flow path RR and the refrigerant flow path (RR). When the refrigerant having a temperature higher than the freezing point flows in the refrigerant flow path RR, ice I generated in the finger member 300 may be separated from the finger member 300.

It might be.

A connection hole 210 may be formed in the evaporation tube 200 as shown in FIG. 2. The finger member 300 may be connected to the connection hole 210.

The finger member 300 may be connected to the evaporation tube 200.

For example, a connecting jaw 311 may be formed on the finger member 300 as illustrated in FIG. 1. And, as shown in Figure 2, in a state in which the connecting jaw 311 of the finger member 300 is caught in a portion of the evaporation tube 200 around the connecting hole 210, the connecting jaw of the finger member 300 By laser welding the portion 311 of the evaporation tube 200 around the connection hole 210, the finger member 300 can be connected to the evaporation tube 200. However, the configuration in which the finger member 300 is connected to the evaporation tube 200 is not particularly limited, and in the state where the connection protrusion (not shown) is formed by burring processing around the connection hole 210, the finger member After inserting the 300 into the connection hole 210, the finger member 300 is connected to the evaporation tube 200 by laser welding the finger member 300 to the connection protrusion of the connection hole 210. Even a configuration is possible.

The number of finger members 300 connected to the evaporation tube 200 is not particularly limited, and any number is possible.

A flow space SP may be formed in the finger member 300. The flow space SP may be connected to the refrigerant flow path RR of the evaporation tube 200 so that the refrigerant enters and exits. Accordingly, the refrigerant flowing in the refrigerant passage RR of the evaporation tube 200 may also flow in the flow space SP of the finger member 300. As such, since the refrigerant flows through the flow space SP of the finger member 300, the formation of ice I on the finger member 300 can be made faster. The upper portion of the flow space SP is opened to be connected to the refrigerant passage RR of the evaporation tube 200 and the lower portion can be closed. However, the configuration of the flow space SP is not particularly limited, and any configuration known in the art can be used as long as it can be connected to the refrigerant flow path RR so that the refrigerant in the refrigerant flow path RR of the evaporation tube 200 enters and exits.

The finger member 300 may include a cylindrical portion 310 and a hemisphere portion 320. The cylindrical portion 310 may be connected to the evaporation tube 200. To this end, the above-described connection jaw 311 connected to the connection hole 210 of the evaporation tube 200 may be formed in the cylindrical portion 310. The cylindrical portion 310 may be cylindrical as illustrated in FIG. 1. The hemisphere part 320 may be connected to the lower end of the cylindrical part 310. For example, the hemisphere part 320 may be integral with the cylindrical part 310 and connected to the lower end of the cylindrical part 310. However, the configuration in which the hemisphere portion 320 is connected to the lower end of the cylindrical portion 310 is not particularly limited, and any known configuration such as connection by sealing fit is possible. The hemisphere part 320 may have a hemisphere shape as illustrated in FIG. 1. However, the configuration and shape of the finger member 300 is not particularly limited, and any configuration and shape may be known as long as it is a configuration and shape in which the flow space SP can be formed.

The heat transfer obstacle member 400 may be provided in at least a portion of the flow space SP of the finger member 300. For example, the heat transfer obstacle member 400 may be provided in a portion of the flow space SP of the cylindrical portion 310 of the finger member 300, as shown in FIG. However, the portion of the flow space SP of the finger member 300 provided with the heat transfer obstacle member 400 is not particularly limited, and may be provided in any part of the flow space SP of the finger member 300.

The heat transfer obstruction member 400 may interfere with heat transfer between the water contacting the finger member 300 and the refrigerant in the flow space SP. For example, the heat transfer obstruction member 400 may be made of an insulating material to prevent heat transfer between the water contacting the finger member 300 and the refrigerant in the flow space SP. Accordingly, by varying the shape or configuration of the heat transfer obstacle member 400, it is possible to generate ice (I) of various shapes on the finger member (300).

The heat transfer obstruction member 400 may have a shape corresponding to at least a part of the finger member 300. For example, the heat transfer obstacle member 400 may have a cylindrical shape corresponding to the cylindrical portion 310 of the finger member 300 as shown in FIG. 1. However, the shape of the heat transfer obstruction member 400 is not particularly limited, and any shape is possible as long as it corresponds to at least a part of the finger member 300, and is provided in the flow space SP of the finger member 300 to provide a finger. If the shape can prevent the heat transfer between the water contacting the member 300 and the refrigerant in the flow space SP, a shape that does not correspond to the finger member 300 is also possible.

The length of the heat transfer obstacle member 400 may be shorter than the length of the finger member 300. Accordingly, as shown in FIG. 2, the flow space SP of the finger member 300 may have a portion provided with and without a heat transfer obstruction member 400. For example, the length of the heat transfer preventing member 400 is shorter than the length of the finger member 300 as shown in FIG. 1, but may be a length substantially similar to the length of the cylindrical portion 310 of the finger member 300. However, the length of the heat transfer obstruction member 400 is not particularly limited, and is shorter than the length of the finger member 300, so that the flow space SP of the finger member 300 is provided with a portion provided with the heat transfer obstruction member 400. Any length can be any length as long as there can be a portion that is not.

A connection passage RC may be formed in the heat transfer obstacle member 400. The connection flow path RC is a portion of the flow path SP of the finger member 300, which is not provided with the refrigerant flow path RR of the evaporation tube 200 and the heat transfer obstacle member 400, as shown in FIG. For example, a portion of the flow space SP of the hemisphere portion 320 of the finger member 300 may be connected. Therefore, the refrigerant flowing through the refrigerant passage RR of the evaporation tube 200 flows through the connection passage RC of the heat transfer obstruction member 400, the flow space of the finger member 300 in which the heat obstruction member 400 is not provided. The part of (SP) can be accessed.

The inner diameter of the connection passage RC may be at least partially smaller than the outer diameter of the heat transfer obstruction member 400. As a result, at least a portion of the heat transfer obstacle member 400 has a heat transfer interference thickness T from the inner surface of the connection flow path RC through which the refrigerant flows, as shown in FIG. 2, to the outer surface of the heat transfer obstacle member 400. You can.

And, the heat transfer barrier thickness T of the heat transfer barrier member 400 from the inner surface of the heat transfer barrier member 400 to the outer surface of the connection passage RC is at least partially changed in the longitudinal direction of the heat transfer barrier member 400 The inner diameter of (RC) may be at least partially different in the longitudinal direction of the heat transfer preventing member 400. The connection flow path RC may be formed along the longitudinal direction of the heat transfer obstruction member 400 in the central portion of the heat transfer obstruction member 400 as shown in FIGS. 1 and 2.

The heat transfer barrier thickness T defined as described above of the heat transfer barrier member 400 is changed in the longitudinal direction of the heat transfer barrier member 400 in the flow space SP of the finger member 300, and thus the finger member 300 ), The flow space (SP) of the heat transfer interfering member 400 has a portion where heat transfer with the refrigerant is relatively poor compared to other portions and a portion where heat transfer is well performed. Thereby, various shapes of ice I can be generated on the finger member 300.

For example, the connection passage RC may include a constant inner diameter portion RT and an enlarged inner diameter portion RE connected to a lower end of the constant inner diameter portion RT, as illustrated in FIGS. 1 and 2. The constant inner diameter portion RT may have a constant inner diameter that is smaller than the outer diameter of the heat transfer obstacle member 400 in a predetermined distance in the longitudinal direction of the heat transfer obstacle member 400. In addition, the enlarged inner diameter portion RE may have a larger inner diameter toward the lower side in the longitudinal direction of the heat transfer obstruction member 400.

Accordingly, in the first embodiment of the ice-making evaporator 100 according to the present invention, a flow space SP in which a constant inner diameter portion RT of the connecting flow path RC is located in the cylindrical portion 310 of the finger member 300 Part of) may be relatively poor heat transfer with the refrigerant by the heat transfer obstacle member 400. In addition, the couple of the flow space SP in which the enlarged inner diameter portion RE of the connecting flow path RC is located among the cylindrical portions 310 of the finger member 300 becomes better to heat transfer with the refrigerant toward the lower side. In addition, in the flow space SP of the hemisphere portion 320 of the finger member 300, which is not provided with the heat transfer obstruction member 400, heat transfer with the refrigerant is relatively better than other parts. As a result, as shown in FIG. 3, spherical ice I may be generated on the finger member 300.

The first embodiment of the evaporator 100 for ice making according to the present invention may further include a partition member 500.

The partition member 500 may be provided in at least one of the refrigerant passage RR of the evaporation tube 200 and the flow space SP of the finger member 300.

It may flow in the above-described connection flow path (RC) of the heat transfer obstacle member 400 provided in a portion of the flow space (SP) of (310). In addition, the refrigerant flowing through the connection passage RC of the heat transfer obstacle member 400 and the portion of the flow space SP of the hemisphere portion 320 of the finger member 300 without the heat transfer obstacle member 400 is heat transfer. The connecting passage RC of the obstruction member 400 may be flowed to flow into the refrigerant passage RR of the evaporation tube 200 by the first compartment 510.
