The first embodiment of the ice-making evaporator 100 according to the present invention may include an evaporation tube 200, a capillary tube 300, a finger member 400, and a refrigerant discharge tube 500.

The evaporation tube 200 may be included in a refrigeration cycle (not shown) together with the capillary tube 300. The evaporation tube 200 may have a flow space 210 formed therein. As illustrated in FIGS. 4 to 6, a refrigerant supplied by the capillary tube 300, for example, a refrigerant at a temperature below the freezing point or a refrigerant at a temperature higher than the freezing point, may flow in the flow space 210.

The evaporation tube 200, for example, as shown in Figures 1 to 3, the flow space 210 is formed therein may be a long rectangular tube in the longitudinal direction. However, the shape of the evaporation tube 200 is not particularly limited, and any shape can be used as long as the flow space 210 can be formed therein.

As shown in FIGS. 2 and 3, a finger connection hole 220 connected to the flow space 210 may be formed in the evaporation tube 200. The upper end of the finger member 400 may be inserted into and connected to the finger connection hole 220. The number of finger connection holes 220 is not particularly limited, and any number can be used as long as it corresponds to the number of finger members 400.

In addition, a pipe connection hole 240 through which the first through hole 230 and the refrigerant discharge tube 500 through which the capillary tube 300 passes is connected may be formed on one side of the evaporation tube 200.

The capillary tube 300 may be included in the refrigeration cycle together with the evaporation tube 200 as described above. The capillary tube 300 may be directly connected to the evaporation tube 200. Accordingly, as the capillary tube 300 and the evaporator tube 200 are connected by separate connection tubes (not shown), the refrigerant having a temperature below the freezing point discharged from the capillary tube 300 flows around the connection tube. The temperature may not rise due to heat transfer from. Therefore, the refrigerant having a temperature below a freezing point of a lower temperature than the case where the capillary tube 300 and the evaporation tube 200 are connected by a separate connection pipe can be supplied to the evaporation tube 200 through the capillary tube 300. Accordingly, since the finger member 400 connected to the evaporation tube 200 may be filled with a temperature below a freezing point of a lower temperature, the finger member 400 does not have a diaphragm provided in the finger member 400 as in the prior art. In the ice (I) can be generated.

The capillary tube 300 may be connected to a condenser (not shown) included in the refrigeration cycle. Refrigerant, for example, a refrigerant at a temperature below the freezing point or a refrigerant at a temperature higher than the freezing point, may be supplied to the flow space 210 of the evaporation tube 200 by the capillary tube 300. When a refrigerant having a temperature higher than the freezing point is supplied to the flow space 210 of the evaporation tube 200 by the capillary tube 300, the capillary tube 300 is connected to the outlet of a compressor (not shown) included in the refrigeration cycle. Can be. For example, a bypass line (not shown) may be connected to a refrigerant flow line (not shown) connecting the compressor outlet and the condenser inlet and a refrigerant flow line connecting the condenser outlet and the capillary 300 inlet. In addition, the bypass line may be provided with an on-off valve (not shown). And, by opening and closing the valve, the compressor outlet and the capillary 300 inlet are connected by a bypass line, so that a refrigerant having a temperature higher than the freezing point discharged from the compressor outlet can be introduced into the capillary 300 inlet.

When a refrigerant having a temperature below the freezing point is supplied to the flow space 210 of the evaporation tube 200 by the capillary tube 300, as illustrated in FIGS. 4 and 5, ice (I) is applied to the finger member 400.

In addition, when the refrigerant having a temperature higher than the freezing point is supplied to the flow space 210 of the evaporation tube 200 by the capillary tube 300, the ice I generated in the finger member 400 as shown in FIG. It can be separated from the finger member 400.

As illustrated in FIG. 3, the capillary tube 300 penetrates the above-described first through hole 230 formed on one side of the evaporation tube 200, for example, on one side of the evaporation tube 200, and at least a part of the evaporation tube 200 It may be provided in the flow space 210. In this case, the capillary tube 300 may extend from the flow space 210 to the other side of the evaporation tube 200. As a result, as illustrated in FIGS. 4 to 6, the refrigerant may be first supplied to a portion of the flow space 210 on the other side of the evaporation tube 200. Then, the refrigerant supplied to a portion of the flow space 210 on the other side of the evaporation pipe 200 flows through the flow space 210 to a portion of the flow space 210 on one side of the evaporation pipe 200 while the evaporation pipe 200 ) Inside the plurality of finger members 400 connected to each other, for example, the connection space 410 formed in each of the plurality of finger members 400 may be sequentially filled.

However, the configuration in which the capillary tube 300 is directly connected to the evaporation tube 200 is not particularly limited, and the refrigerant in the flow space 210 of the evaporation tube 200, for example, a refrigerant at a temperature below the freezing point or a temperature higher than the freezing point Any configuration known in the art can be used as long as it can supply a refrigerant.

On the other hand, instead of the capillary 300, an expansion valve (not shown) that may be included in the refrigeration cycle and a connection pipe (not shown) connected to the expansion valve may be used instead of the capillary 300. In this case, the connector is wrapped with an insulating member (not shown) or the like so that the temperature of the refrigerant at a temperature below the freezing point discharged from the expansion valve does not rise due to heat transfer from the surroundings, or below the freezing point from the surroundings. The distance between the evaporation tube 200 and the expansion valve may be relatively short so that heat transfer is minimized with a refrigerant having a temperature of.

The finger member 400 may be connected to the evaporation tube 200. For example, a plurality of finger members 400 may be connected to the evaporation tube 200. The number of the finger members 400 is not particularly limited, and any number is possible and one is possible.

The refrigerant in the flow space 210 of the evaporation tube 200 may be filled into the finger member 400, for example, a refrigerant having a temperature below the freezing point or a refrigerant having a temperature higher than the freezing point.

In addition, a connection space 410 connected to the flow space 210 of the evaporation tube 200 may be formed in the finger member 400. For example, when the upper portion of the connection space 410 is opened and the upper portion of the finger member 400 is inserted into the finger connection hole 220 of the evaporation pipe 200, the open upper portion of the connection space 410 is the evaporation pipe 200 ) May be connected to the flow space 210. However, the configuration in which the inside of the finger member 400, for example, the connection space 410 is connected to the flow space 210 of the evaporation tube 200 is not particularly limited, and any known configuration is possible.

When the refrigerant having a temperature below the freezing point is filled in the connection space 410 of the finger member 400, when the finger member 400 is immersed in water contained in the drip tray WT, as shown in FIGS. 4 and 5, the connection Finger by heat exchange between the refrigerant at a temperature below the freezing point of the space 410 and the water contained in the drip tray WT, that is, heat transfer from the water contained in the drip tray WT to the refrigerant at a temperature below the freezing point of the connection space 410 Ice (I) may be generated in the member 400.

In addition, when ice (I) is generated in the finger member 400, when the refrigerant having a temperature higher than the freezing point is filled in the connection space 410 of the finger member 400, the connection space 410 of the finger member 400 ) Heat exchange between the refrigerant having a temperature higher than the freezing point and the ice (I) generated in the finger member 400, that is, the finger member 400 from the refrigerant having a temperature higher than the freezing point of the connection space 410 of the finger member 400 By heat transfer to the ice (I) generated in, the ice (I) generated in the finger member 400 can be separated from the finger member 400 as shown in FIG.

In this case, the drip tray WT may be moved to a position where the ice I separated from the finger member 400 is not disturbed by movement, for example, to a position where water is not contained, as shown in FIG. 6.

Meanwhile, water (I) may be generated on the finger member (400) by spraying water by the water spray unit (not shown) on the finger member (400).

As described above, since the ice member I may be generated even if the finger member 400 is not provided with a diaphragm as in the prior art, the size of the finger member 400 is smaller than in the prior art, and the distance between the finger members 400 is also small. The finger member 400 can also be made thin. Therefore, the evaporator 100 for ice making is simple, but the size can be reduced and manufacturing can be easy.

The refrigerant discharge pipe 500 may be connected to the evaporation pipe 200. For example, the refrigerant discharge pipe 500 may be connected to a pipe connection hole 240 formed in the evaporation pipe 200.

The refrigerant evaporated from the flow space 210 of the evaporation tube 200 and the inside of the finger member 400, for example, the connection space 410 of the finger member 400 may be discharged through the refrigerant discharge tube 500.

The refrigerant discharge pipe 500 may be connected to a compressor included in the refrigeration cycle. Accordingly, the refrigerant evaporated in the flow space 210 of the evaporation pipe 200 and the connection space 410 of the finger member 400 and introduced into the refrigerant discharge pipe 500 flows through the refrigerant discharge pipe 500 to form a refrigeration cycle. It can enter the compressor.

The refrigerant discharge pipe 500 may be connected to a portion of the evaporation pipe 200 higher than the portion of the evaporation pipe 200 to which the capillary tube 300 is connected. For example, the refrigerant discharge pipe 500 may be connected to the top of the evaporation pipe 200. As a result, as illustrated in FIG. 2, the tube connection hole 240 may be formed in the evaporation tube 200 higher than the first through hole 230.

The refrigerant in the gas phase evaporated in the flow space 210 of the evaporation tube 200 and the interior of the finger member 400, for example, in the connection space 410 of the finger member 400, has a smaller density than the liquid refrigerant, and thus the evaporation tube 200 ). Therefore, when the refrigerant discharge pipe 500 is connected to the upper portion of the evaporation pipe 200, the flow space 210 of the evaporation pipe 200 and the interior of the finger member 400, for example, the connection space 410 of the finger member 400 ), the refrigerant in the gas phase evaporated can be easily discharged through the refrigerant discharge pipe 500.

However, the portion of the evaporation pipe 200 to which the refrigerant discharge pipe 500 is connected and the configuration in which the refrigerant discharge pipe 500 is connected to the evaporation pipe 200 are not particularly limited, and the flow space 210 of the evaporation pipe 200 ) And the inside of the finger member 400, for example, any part and any known configuration as long as the refrigerant and evaporated refrigerant in the connection space 410 of the finger member 400 can be discharged.
