Evaporator for ice maker

The first embodiment of the evaporator 100 for an ice maker according to the present invention may include a first flow path forming plate 200, a second flow path forming plate 300, and an immersion member 400.

At least a portion of a refrigerant passage (PR) through which the refrigerant flows may be formed in the first passage forming plate 200. For example, as shown in FIG. 1, a flow path groove (GV) having a semicircular cross section and open on one side is formed in the first flow path forming plate 200 to form at least a portion of the refrigerant flow path (PR). However, the configuration formed on the first flow path forming plate 200 to form at least a portion of the refrigerant path (PR) is not particularly limited, and any configuration is possible as long as it forms at least a portion of the refrigerant path (PR).

The second flow path forming plate 300 may be connected to the first flow path forming plate 200 by brazing to complete the refrigerant flow path (PR). For example, the second flow path forming plate 300 is connected to the first flow path forming plate 200 by brazing, as shown in Figure 1, and a channel groove having a semicircular cross section formed in the first flow path forming plate 200 ( The refrigerant passage (PR) can be completed by covering one open side of the GV).

In addition, a channel groove with one side open corresponding to the channel groove formed on the first channel forming plate 200 may be formed in the second flow path forming plate 300. In addition, the second channel forming plate 300 is connected to the first channel forming plate 200 by brazing so that the open sides of the channel grooves formed in the first and second channel forming plates 200 and 300, respectively, face each other. The Euro (PR) may be completed.

However, the configuration in which the refrigerant passage (PR) is completed is not particularly limited, and any configuration is possible as long as the second passage forming plate 300 is connected to the first passage forming plate 200 with a braze.

The refrigerant passage (PR), which is completed by connecting the first and second passage forming plates 200 and 300 to each other by brazing, is a first refrigerant passage (PR1) and a second refrigerant passage (PR1) whose ends are connected to each other as shown in FIG. 1. PR2) may be included. Additionally, there may be a plurality of first and second refrigerant passages (PR1, PR2). In addition, one of the plurality of first refrigerant passages (PR1) is connected to a capillary (not shown) or an expansion valve (not shown) included in a refrigeration cycle (not shown) by a first connection pipe (PC1). , one of the plurality of second refrigerant passages (PR2) may be connected to a compressor (not shown) included in the refrigeration cycle through a second connection pipe (PC2). As a result, a zigzag-shaped refrigerant passage (PR) can be formed.

Meanwhile, a brazing member (BM) may be provided between the first and second flow path forming plates (200,300) and melts during brazing to connect the first and second flow path forming plates (200,300).

The brazing member BM may be in the form of a film, for example. However, the shape of the brazing member (BM) is not particularly limited, and as long as it is provided between the first and second flow path forming plates (200 and 300) and is melted during brazing to connect the first and second flow path forming plates (200 and 300), what shape can it have? It is also possible.

The brazing member (BM) may be made of the same material as the first and second flow path forming plates (200,300). If the brazing member (BM) is made of the same material as the first and second flow path forming plates (200,300), the connection of the first and second flow path forming plates (200,300) by melting the brazing member (BM) can be made more firmly. there is.

The brazing member BM and the first and second flow path forming plates 200 and 300 may be made of, for example, stainless steel. If the brazing member (BM) and the first and second channel forming plates (200,300) are made of stainless steel, the brazing member (BM) and the first and second channel forming plates (200,300) may not be easily corroded. , the generation of contaminants due to corrosion can be minimized. Accordingly, since the ice maker (IM) equipped with the ice maker evaporator 100 can be minimized from being contaminated by contaminants, the sanitation of the ice maker (IM) can be improved.

However, the brazing member (BM) and the first and second channel forming plates (200,300) may be made of a material other than stainless steel, and the brazing member (BM) may be made of a material different from the first and second channel forming plates (200,300). It may come true.

The immersion member 400 may be connected to the second flow path forming plate 300. For example, a fitting hole (H) may be formed in the second flow path forming plate 300 as shown in FIG. 1. Then, one end of the immersion member 400 is inserted into the fitting hole (H) of the second flow path forming plate 300 and laser welded, so that the immersion member 400 can be connected to the second flow path forming plate 300. .

However, the configuration in which the immersion member 400 is connected to the second flow path forming plate 300 is not particularly limited, and is connected by laser welding directly to the second flow path forming plate 300 rather than being inserted into the fitting hole (H). Any configuration known to the public is possible.

A first additional refrigerant passage (PA1) in which the additional refrigerant passage (PA) formed in the immersion member 400 by the partition member 410 is connected to the first refrigerant passage (PR1) of the refrigerant passage (PR), and a first additional refrigerant passage (PA1) It can be divided into a refrigerant passage (PA1) and a second additional refrigerant passage (PA2) connected to the second refrigerant passage (PR2) of the refrigerant passage (PR).

To this end, as shown in FIG. 1, one end of the partition member 410 may be connected to a portion of the second passage forming plate 300 between the first and second refrigerant passages PR1 and PR2. One end of the partition member 410 may be connected to a portion of the second passage forming plate 300 between the first and second refrigerant passages PR1 and PR2 by, for example, a brazing member BM. However, the configuration in which one end of the partition member 410 is connected to the portion of the second flow path forming plate 300 between the first and second refrigerant paths PR1 and PR2 is not particularly limited, and any known configuration is possible.

The other end of the partition member 410 is spaced a predetermined distance from the bottom of the immersion member 400 as shown in FIG. 1, or the other end of the partition member 410 is provided with first and second additional refrigerant passages (PA1 and PA2). ) may be formed with a connection hole (not shown) connecting them to each other.

As a result, as shown in FIGS. 3 and 5, the refrigerant flowing through the first refrigerant passage (PR1) of the refrigerant passage (PR) flows into the first additional refrigerant passage (PA1) of the immersion member 400, thereby 2 After flowing into the additional refrigerant passage (PA2), it can flow into the second refrigerant passage (PR2) of the refrigerant passage (PR).

Meanwhile, in the first embodiment of the evaporator 100 for an ice maker according to the present invention, contaminants generated from the brazing member BM provided between the first and second flow path forming plates 200 and 300 are transmitted through the first and second flow paths.
