As shown in FIG. 4, the evaporation tube 300 may be provided in a spiral shape inside the apparatus body 200 containing ice-condensate, for example, in the receiving space 211 of the apparatus body 200. In this way, the evaporation tube 300 is provided inside the apparatus body 200 containing the ice-condensate liquid in a spiral shape, thereby increasing the contact area between the evaporation tube 300 and the ice-condensate liquid contained in the apparatus body 200 Can be. Therefore, cooling of the ice-condensate liquid by the refrigerant flowing inside the evaporation tube 300 can be performed more smoothly and quickly.

One side of the cold water pipe 400 may be connected to a water supply source (not shown). Accordingly, water from the water supply source may flow inside the cold water pipe 400. For example, one side of the cold water pipe 400 may be connected to a water supply source by a connection pipe (not shown). The water supply source to which one side of the cold water pipe 400 is connected may be a water filter (not shown) that filters water or a water storage tank (not shown) that stores water filtered by the water filter. However, the water supply source to which one side of the cold water pipe 400 is connected is not particularly limited, and any known water source is connected to one side of the cold water pipe 400 to allow water to flow inside the cold water pipe 400. It is possible.

For example, the cold water pipe 400 may be provided in the receiving space 211 of the apparatus body 200 containing ice-condensate, as shown in FIG. 4. Accordingly, as described above, water flowing in the cold water pipe 400 may be cooled by the ice-condensate liquid cooled by a refrigerant having a freezing point or less flowing through the evaporation pipe 300 to become cold water. The other side of the cold water pipe 400 may be connected to, for example, a water discharge member (not shown) such as a faucet or a cock, a cold water tank (not shown), or a carbonated water dispenser (not shown) that requires cold water. In addition, the cold water produced by cooling water flowing inside the cold water pipe 400 by the ice stock solution may be supplied to a water discharge member, a cold water tank, or a carbonated water dispenser.

As shown in FIG. 4, the cold water pipe 400 may be provided in a spiral shape inside the device body 200 containing ice-condensate, for example, in the receiving space 211 of the device body 200. In this way, the cold water pipe 400 is provided inside the apparatus body 200 containing the ice-condensate liquid in a spiral shape, so that the contact area between the cold water pipe 400 and the ice-condensate liquid contained in the apparatus body 200 is increased.

It is possible to circulate between the spaces inside the apparatus body 200 outside the evaporation tube 300.

Accordingly, the ice condensate in the space inside the device body 200 inside the spiral evaporation tube 300, cooled by a cold refrigerant below the freezing point flowing inside the evaporation tube 300, is as shown in FIG. Water flowing in the inside of the cold water pipe 400 may be cooled by flowing to the spiral cold water pipe 400 provided in the space inside the apparatus body 200 outside the spiral evaporation pipe 300. The ice-condensate whose temperature is increased by cooling the water flowing inside the cold water pipe 400 flows into the space inside the device body 200 inside the spiral evaporation pipe 300 and is below the freezing point flowing inside the evaporation pipe 300 It can be cooled again by the refrigerant of. Therefore, since the water flowing inside the cold water pipe 400 can be cooled by a cooler refrigerant, the water flowing inside the cold water pipe 400 can be cooled more quickly.

In this case, the helical virtual center line formed by the evaporation pipe 300 and the helical virtual center line formed by the cold water pipe 400 may be parallel or the same. Accordingly, the spiral evaporation tube 300 and the spiral cold water tube 400 are formed in the device body 200 so that a space in which the ice-condensate liquid can be smoothly circulated by the stirring unit 500 is formed in the device body ( 200) Can be placed inside each.

In addition, the helical height HE formed by the evaporation pipe 300 may be smaller than the helical height HC formed by the cold water pipe 400. Accordingly, the stirring member 510, which will be described later, included in the stirring unit 500 may be positioned above or below the spiral evaporation tube 300 inside the spiral cold water tube 400, as described later. As a result, the ice-condensate liquid inside the device body 200 by the rotation of the stirring member 510 is in the space inside the device body 200 inside the spiral evaporation tube 300 and the device outside the spiral evaporation tube 300 It is possible to circulate between the spaces inside the main body 200.

In addition, the helical pitch PE formed by the evaporation pipe 300 may be larger than the helical pitch PC formed by the cold water pipe 400. Accordingly, a longer length of the cold water pipe 400 can be provided inside the device body 200, so that more water can be made into cold water. In this case, the evaporation pipe 300 may form a spiral shape having a pitch PE in which a space in which ice IC can be formed is formed as shown in FIG. 5. In this way, when ice (IC) is formed between the spiral evaporation tube 300, cooling of the ice condensate flowing through the space inside the device body 200 inside the spiral evaporation tube 300 can be made faster. .

The stirring unit 500 may be provided in the device body 200 to stir the ice-condensate contained in the device body 200.

The stirring unit 500 is a space inside the device body 200 inside the spiral evaporation tube 300 and the inside of the device body 200 outside the spiral evaporation tube 300. The ice-condensate can be stirred to circulate between the spaces of.

Thereby, as shown in Fig. 5, the ice condensate in the space inside the device body 200 inside the spiral evaporation tube 300, cooled by a cold refrigerant below the freezing point flowing inside the evaporation tube 300 The silver flows to the spiral cold water pipe 400 provided in the space inside the device body 200 outside the spiral evaporation tube 300, and cools the water flowing inside the cold water pipe 400. In addition, the ice-condensate, whose temperature is increased by cooling the water flowing inside the cold water pipe 400, flows into the space inside the device body 200 inside the spiral evaporation pipe 300 and flows inside the evaporation pipe 300. It can be cooled again by a refrigerant below freezing point. Therefore, since the water flowing inside the cold water pipe 400 can be cooled by a cooler refrigerant, the water flowing inside the cold water pipe 400 can be cooled more quickly.

The stirring unit 500 may include a stirring member 510 and a motor 520.

The stirring member 510 is located inside the device body 200 and may stir and circulate the ice-condensate contained in the device body 200. The stirring member 510 may include a shaft connection part 511 and a blade 512 as shown in FIG. 3.

The shaft connection part 511 may be connected to the rotation shaft 521 of the motor 520. To this end, a shaft insertion hole 511a to which the rotation shaft 521 of the motor 520 is inserted and connected as shown in FIG. 3 may be formed in the shaft connection part 511. However, the configuration in which the shaft connection part 511 is connected to the rotation shaft 521 of the motor 520 is not particularly limited, and any known configuration may be used.

The blade 512 may be provided on the shaft connection part 511. As shown in FIG. 5, the blade 512 may stir and circulate the ice condensate as shown in FIG. 5 by rotating the shaft connection part 511 by the rotation of the rotation shaft 521 of the motor 520. As shown in FIGS. 2 to 4, a plurality of blades 512 may be provided on the shaft connection part 511. However, the number of the plurality of blades 512 provided in the shaft connection part 511 is not particularly limited and may be one.

The blade 512 may be provided on the shaft connection part 511 so as to form a predetermined angle α with a virtual line perpendicular to the rotation axis 521 of the motor 520 as shown in FIG. 3. Accordingly, not only a force in the rotational direction of the rotational shaft 521 of the motor 520 but also a force downward in the axial direction may act on the ice-axis liquid by the blade 512. Accordingly, the ice-condensate liquid around the blade 512 may flow downward while being stirred as shown in FIG. 5 to circulate the ice-condensate liquid.

The predetermined angle α formed by the blade 512 with the virtual line perpendicular to the rotation axis 521 of the motor 520 may be 45 degrees or less. When the predetermined angle α formed by the blade 512 with the virtual line perpendicular to the rotational axis 521 of the motor 520 is greater than 45 degrees, the force acting axially downward on the ice axis liquid by the blade 512 is applied to the blade ( 512) may be less than the force acting on the ice-axis liquid in the rotational direction of the rotational shaft 521 of the motor 520. Accordingly, although the ice-condensate liquid may be stirred by the blade 512, it is difficult for the ice-condensate to flow downward, so that circulation of the ice-condensate may be difficult. Therefore, the predetermined angle α between the blade 512 and the imaginary line perpendicular to the rotational axis 521 of the motor 520, which can be circulated while being stirred by the blade 512, is preferably 45 degrees or less. Do.

If the blade 512 is located below the point 0.7 times the spiral height (HC) formed by the cold water pipe 400, the size of the space inside the cold water pipe 400 under the blade 512 decreases, The evaporator 300 having a size capable of sufficiently cooling the condensate liquid as required may not be provided inside the cold water pipe 400 under the blade 512.

Therefore, when the blade 512 is located on the spiral evaporation tube 300 inside the spiral cold water tube 400, the evaporator 300 having a size capable of sufficiently cooling the ice-condensate liquid as required is the blade 512 In order to be provided inside the cold water pipe 400 below, it is preferable that the blade 512 is positioned above a point at which the height of the spiral shape (HC) of the cold water pipe 400 is 0.7 times higher.

In addition, when the blade 512 is located under the spiral evaporation tube 300 from the inside of the spiral cold water pipe 400, the blade 512 is 0.3 times the spiral height HC formed by the cold water pipe 400 It can be located below the point where it becomes.

If the blade 512 is located above a point 0.3 times the spiral height (HC) formed by the cold water pipe 400, the size of the space inside the cold water pipe 400 above the blade 512 becomes smaller, so that the ice condensate liquid The evaporator 300 having a size capable of sufficiently cooling as required may not be provided inside the cold water pipe 400 on the blade 512.

Therefore, when the blade 512 is located below the spiral evaporation tube 300 inside the spiral cold water tube 400, the evaporator 300 having a size capable of sufficiently cooling the ice-condensate liquid as required is provided with the blade 512 ) In order to be provided inside the cold water pipe 400 above, it is preferable that the blade 512 is positioned below a point at which the height of the spiral shape (HC) formed by the cold water pipe 400 is 0.3 times higher.
