In addition, as will be described later, the device body 200 may be formed integrally with the cold water generating pipe 400 made of metal and die casting.

The water tank 300 may be provided in the device body 200. As described above, a tank insertion space 210 with one side open is formed in the device body 200, and at least a part of the water tank 300 through the open one side of the tank insertion space 210 is formed in the tank insertion space 210 ), the water tank 300 may be provided in the device body 200. Accordingly, an embodiment of the cold water manufacturing apparatus 100 according to the present invention may have a smaller size. However, the configuration in which the water tank 300 is provided in the device body 200 is not particularly limited, and any known configuration may be used.

The water tank 300 may be connected to a water supply source (not shown) such as water. Accordingly, water from the water supply source may be introduced into the water tank 300 and received as shown in FIGS. 5 and 6.

However, the configuration in which the tank cover 320 is connected to the device body 200 so as to cover the open side of the tank body 310 is not particularly limited, and any known configuration may be used.

The tank cover 320 may be provided with an inlet 321 and a connector 322 as shown in FIG. 4. The inlet 321 may be connected to a water supply source such as water through a connection pipe. Accordingly, the water of the water supply source can flow through the connection pipe and flow into the storage space 311 of the tank body 310 through the inlet 321 as shown in FIGS. 5 and 6. The connector 322 may be connected to the cold water generating pipe 400. As a result, water in the storage space 311 of the tank body 310 may flow into the cold water generation pipe 400 through the connector 322. The connector 322 may be connected to the cold water generating pipe 400 by, for example, a fitting member FT. However, the configuration in which the connector 322 is connected to the cold water generating pipe 400 is not particularly limited, and any known configuration may be used.

The tank cover 320 may be provided with a temperature sensor ST capable of measuring the temperature of water in the storage space 311 of the tank body 310 as shown in FIG. 4.

The cold water generation pipe 400 may be provided in the device body 200 to be connected to the water tank 300. In addition, water accommodated in the water tank 300 may be discharged after flowing into the cold water generating pipe 400 as shown in FIGS. 5 and 6.

The cold water generating pipe 400 may be formed integrally with the device body 200. Accordingly, an embodiment of the cold water manufacturing apparatus 100 according to the present invention may have a smaller size. For example, the cold water generation pipe 400 and the device body 200 are made of metal, and the cold water generation pipe 400 may be formed integrally with the device body 200 by die casting. The cold water generating pipe 400 may be made of, for example, stainless steel. However, the metal forming the cold water generating pipe 400 is not particularly limited, and any metal may be used as long as it can be formed integrally with the device body 200 by die casting.

In this case, as shown in FIGS. 5 and 6, the cold water generation pipe 400 may be located in the device body 200 so as to surround the tank insertion space 210 of the device body 200. Accordingly, when the device body 200 is cooled by the cooling unit 500 and the water flowing through the cold water generating pipe 400 is cooled, the water flowing through the cold water generating pipe 400 causes the Water in the water tank 300 inserted into the tank insertion space 210 may be cooled. Accordingly, the water in the water tank 300 may be cooled not only by cooling the device body 200 by the cooling unit 500, but also by water flowing through the cold water generating pipe 400. Accordingly, in an embodiment of the cold water manufacturing apparatus 100 according to the present invention, cold water manufacturing efficiency may be improved. The cold water generating pipe 400 may be formed in a spiral shape on the side of the device body 200 so as to surround the tank insertion space 210 of the device body 200 as shown in FIG. 4. Accordingly, the heat transfer area of the cold water generation pipe 400 and the device body 200 can be increased, and heat transfer between the water flowing through the cold water generation pipe 400 and the water of the water tank 300 can be smoothly performed. Therefore, cooling of the water flowing through the cold water generation pipe 400 by cooling the device body 200 of the cooling unit 500 and cooling the water in the water tank 300 by the water flowing through the cold water generation pipe 400 It can be done faster than this. Thereby, in an embodiment of the cold water manufacturing apparatus 100 according to the present invention, the cold water manufacturing efficiency may be improved.

In this way, by cooling the device body 200 by the cooling unit 500, the water accommodated in the water tank 300 and the water in the cold water generating pipe 400 may be cooled. Accordingly, the water of the water supply source is first cooled in the water tank 300, and the first cooled water is cooled secondarily in the cold water generation pipe 400 during the water outlet process, so that cold water below a predetermined temperature may be obtained. In this way, since the water of the water supply source is first cooled in the water tank 300 and secondarily cooled in the cold water generating pipe 400, an embodiment of the cold water manufacturing apparatus 100 according to the present invention is reduced in size. Not only can the cold water production efficiency be improved.

The cooling unit 500 may include a thermoelectric module 510. The thermoelectric module 510 may be installed such that the cooling side is in contact with the cold sink 220 of the device body 200 as shown in FIGS. 2, 4 and 6. Accordingly, when power is applied to the thermoelectric module 510, the cold sink 220 of the device body 200 is cooled by the thermoelectric module 510, so that the device body 200 may be cooled.

The cooling unit 500 may further include a heat transfer member 520, a heat pipe 530, a heat sink (not shown), and a blowing fan (not shown). The heat transfer member 520 may be connected to be in contact with the heating side of the thermoelectric module 510. In addition, one side of the heat pipe 530 may be connected to the heat transfer member 520. In addition, the other side of the heat pipe 530 may be connected to the heat sink. In addition, the blowing fan may be provided in the heat sink. Accordingly, heat generated on the heating side of the thermoelectric module 510 is transferred to the heat sink through the heat transfer member 520 and the heat pipe 530 to be radiated by the heat sink and the blowing fan. And, since the heat sink provided with the blowing fan is not directly in contact with the heating side of the thermoelectric module 510 and is connected to the heating side of the thermoelectric module 510 through the heat pipe 530, the cooling unit 500 Installation freedom can be increased.

The configuration of the cooling unit 500 is not particularly limited, such as including an evaporation tube through which a refrigerant flows, and cooling the device body 200 to flow the water of the water tank 300 and the cold water generation pipe 400 Any known configuration is possible as long as it is a configuration that can be provided in the device body 200 to be cooled.

The insulating member 600 may wrap the device body 200 and the tank cover 320 of the water tank 300 as shown in FIGS. 1 and 2 and FIGS. 5 and 6. Accordingly, it is possible to prevent the external heat from being transferred to the water flowing through the water of the water tank 300 and the cold water generation pipe 400 through the tank cover 320 of the device body 200 and the water tank 300. I can.

As shown in FIG. 2 through the sink exposure hole 611, the cold sink 220 of the device body 200 is exposed to the outside, so that the cooling unit 500 is the cold sink 220 of the device body 200. Can be provided in.

As shown in FIG. 3, a member exposure hole 621 may be formed in the heat insulating cover 620.
