FIG. 5 is a view showing a stacked structure of a column portion and a pipe portion of a beverage cooling apparatus according to an embodiment of the present invention. FIG. 6 (a) is a cross- 1 is a cross-sectional view taken along the line AA 'in Fig. 1, and Fig. 6 (b) is a conceptual view showing a modified example of Fig. 6 (a).

5 and 6 (a) and 6 (b), the pipe portion 200 may be further laminated outward from the outer circumferential surface of the column portion 120, that is, the second support portion 122. That is, the pipe section 200 may be wound in one direction on the outer circumferential surface of the second support section 122, and then wound in the opposite direction on the outer circumferential surface thereof to form a layer. 5, the number of the layers constituting the pipe unit 200 is three, but the number of the layers is not limited to any particular one and may be variously set according to the intention of the manufacturer. At this time, the metal plate 230 may be disposed between the pipe part 200 forming one layer and the pipe part 200 forming another layer on the outer side of the second support part 122. The refrigerant pipe 220 constituting the pipe unit 200 is made of a copper material and the copper is more ductile than the stainless steel material forming the beverage pipe 210 and is bent well. The metal plate 230 may be disposed in consideration of the stable support of the metal plate 230 and the thermal conductivity between the respective layers. The metal plate 230 may be formed of a material such as copper, aluminum, or platinum. Therefore, the shapes of the beverage tube 210 and the refrigerant tube 220 are not damaged by the force and heat used when the pipe portion 200 is wound around the second support portion 122.

Referring again to FIG. 1, an embodiment of the present invention may further include a molding part 300. That is, the molding space 300, which is surrounded by the casting metal and surrounds the pipe part 200, may be disposed in the inner space of the cooling chamber 100. The molding part 300 may include at least one of aluminum, copper, and platinum to facilitate heat transfer between the beverage pipe 210 and the refrigerant pipe 220. At this time, the cast metal may flow into the internal space of the body 110 by passing through the first through hole 121a of the first support portion 121 of the pillar 120. And passes through the second through hole 123a of the third supporting portion 123 of the column 120 to penetrate into the space between the bottom of the body 110 and the column 120 to reduce the empty space.

Also, referring to FIG. 1, an embodiment of the present invention may further include a heat insulating member 400. The heat insulating member 400 may be disposed outside the cooling chamber 100 and may receive the pipe portion 200 therein to block the heat transfer of the pipe portion 200 and the heat insulating member 400 from the internal space.

The molding part 300 can maintain the maximum cooling effect of the beverage tube 210 by increasing the contact surface between the coolant pipe 220 and the beverage pipe 210 and can prevent the heat insulating member 400 from being formed outside the molding part 300. [ The cooled temperature of the pipe part 200 and the molding part 300 can be more effectively maintained. As a result, the heat transfer inside and outside the molding part 300 can be minimized, so that the cooling efficiency can be maximized.

The heat insulating member 400 may be glass fiber, polystyrene foam, urethane foam, or the like. For reference, glass fibers are adhered with extremely thin glass fibers by resin bonding, and there is a difference in heat insulating effect depending on the thickness of the fibers. In addition, polystyrene foam is a polystyrene resin in which the polystyrene resin is highly saturated. Furthermore, the urethane foam is a foam produced by the reaction of isocyanate and polyol, and is excellent in the heat insulating property, and forms a heat insulating material by a process of flowing into the liquid phase between the outer and inner case and foaming.

7 is a conceptual diagram of a beverage cooling apparatus according to an embodiment of the present invention, in which a coolant cooling unit 500 is disposed below a cooling chamber 100 in a beverage cooling apparatus according to an embodiment of the present invention to be.

Referring to FIGS. 1 and 7, a coolant cooling unit 500 including a condenser 510 and a compressor 520 may be disposed below the cooling chamber 100. That is, the cooling chamber 100 and the condenser 510 compressor 520 may be disposed perpendicular to the bottom. At this time, the positions where the condenser 510 and the compressor 520 are disposed may be changed as needed. In other words, although not shown in the drawing, a compressor 520 may be disposed at a lower portion of the cooling chamber 100, and a condenser 510 may be disposed at a lower portion of the compressor 520. In addition, it is also possible that the coolant cooling portion 500 is disposed at the upper portion of the cooling chamber 100. In the conventional beverage cooling apparatus, the refrigerant cooling portion such as the condenser and the compressor is arranged on the rear or side portion of the cooling chamber, so that the space occupied by the beverage cooling apparatus is large, and as a result, There has been a limit in using such a beverage cooling apparatus. In order to solve such a problem, in the present invention, by placing the condenser 510 and the compressor 520 at the lower part of the cooling chamber 100 as shown in FIG. 6, the condenser and the compressor are horizontally The space occupied by the beverage cooling apparatus can be reduced, and the space utilization of the beverage cooling apparatus can be further improved.

If necessary, the coolant cooling unit 500 may use a thermoelectric element, such as the condenser 510 and the compressor 520 described above, instead of using the relationship between the volume and the temperature of the fluid. When such a thermoelectric element is used, a Peltier element can be used according to the embodiment. Here, the Peltier element refers to a device that connects ends of different metals to each other and absorbs heat on one side and generates heat on the other side in accordance with the current flowing direction. When such a Peltier element is used, there is an advantage that the apparatus can be made smaller and lighter.

Although not shown in the drawing, a through hole (not shown) may be formed in a part of the body 110. The through hole is provided between the outer surface of the body 110 and the inner surface of the heat insulating member 400 through the through hole to prevent condensation between the outer surface of the body 110 and the inner surface of the heat insulating member 400. [ The condenser 510 and the compressor 520 can be driven to generate a part of the generated heat and the introduced heat can prevent the condensation from being frozen. At this time, one end of a pipe (not shown) may be inserted into the through-hole, and the other end of the pipe may be disposed toward the coolant cooling unit. Accordingly, the condensed water can escape to the outside through the pipe coupled to the through hole in a liquid state without being frozen on the outer surface of the body 110, and the liquid is discharged to the outer surface of the condenser 510 and the compressor 520 It is also possible to cool the driving heat of the condenser 510 and the compressor 520.

The beverage cooling apparatus according to the present invention may further include a controller 600. The controller 600 does not limit the arrangement order of the condenser 510 and the compressor 520 together. The controller 600 may include a temperature controller (not shown) to allow the user to adjust the temperature of the refrigerant or the temperature inside the cooling chamber 100. For example, the temperature controller may be disposed in the coolant cooling unit 500 for cooling the coolant and the temperature of the coolant may be adjusted to control the temperature of the beverage flowing along the inside of the beverage tube 210.

At this time, the controller 600 controls the cooling process of the coolant to cool the coolant so that the temperature of the set beverage is maintained. It is preferable that a temperature sensing sensor (not shown) is provided inside the cooling chamber 100 to control the controller 600 so that the refrigerant cooling unit 500 can be more easily operated. More specifically, the temperature signal sensed by the temperature sensor is input to the controller 600. When the received temperature value is higher than the set temperature value, the controller 600 controls the compressor 520 and the condenser 510 The refrigerant cooling unit 500 such as the thermoelectric element is operated to cool the refrigerant, and when the temperature is lower than the set temperature value, the cooling operation can be stopped.

It is to be understood that the present invention is not limited to the above-described embodiment, and various modifications and changes may be made without departing from the scope of the present invention as claimed in the claims. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention.
