The inlet 21 is formed to be inclined, it is formed to be inclined toward the front toward the lower side to facilitate the entry and exit of the beverage container (2). The inlet 21 is opened and closed by a cover 60 having a corresponding shape. In addition, a gasket 61 may be provided at a circumference of the cover 60 or a front end of the case 20. The gasket 61 may prevent the cool air inside the case 20 from leaking while the cover 60 is closed.

In addition, a cover fixing part 211 is formed at the front end of the case 20 in which the inlet 21 is formed. The cover fixing part 211 is to allow the fixing member 62 provided in the cover 60 to be inserted and fixed, so that the cover 60 can be maintained in a closed state. The cover fixing portion 211 and the fixing member 62 are provided on both left and right sides, respectively, so that the cover 60 can be stably closed.

In addition, a cover coupling part 212 is formed at the lower end of the inlet 21. The cover coupling part 212 is axially coupled with the lower end of the cover 60. Therefore, the cover 60 can rotate the cover coupling portion 212 to the axis to open and close the inlet (21).

On the other hand, the upper surface of the case 20 is formed with an opening 22 for checking the state of the case 20 and the assembly and maintenance of the internal configuration. The opening 22 may be shielded by the opening shielding member 221. Of course, the opening 22 may be formed at another position of the case 20 as necessary.

In addition, a lower surface of the case 20 may be detachably mounted to a bottom surface of the case 20 and provided with a suction grill 23 positioned at an outlet end of the suction duct 11. The suction grille 23 is mounted to the cold air inlet 24 that is opened at the bottom of the case 20.

In this case, the cold air inlet 24 is formed at a predetermined position of the case 20. At this time, the location of the cold air inlet 24 may be formed below the corresponding position where the beverage container 2 is seated when only one beverage container 2 is seated on the stirring member 50. Therefore, the cold air passing through the suction grill 23 is completely directed to the outer surface of the beverage container 2 to cool the beverage container 2.

Meanwhile, a plurality of air holes 231 may be formed on the bottom surface of the suction grill 23. In detail, a plurality of air holes 231 having a small diameter are formed on the bottom surface of the suction grill 23 so that the flow velocity of cold air passes through the outlet end of the suction duct 11, that is, the suction grill 23. It's going to be faster. Therefore, since cold air may form a jet stream while passing through the plurality of air holes 231, it may be defined as a jet hole. The plurality of cold air holes 231 are arranged to have a predetermined interval, and are evenly disposed over the entire surface of the suction grill 23.

The upper end of the suction grille 23 may be bent and extended in an outward direction, and may be detachably mounted to the bottom surface of the case 20 in a form that is caught by the bottom of the case 20. At this time, it will be appreciated that a locking structure for preventing the suction grille 23 from being spaced apart from the bottom surface of the case 20 by the sucked air may be provided.

Meanwhile, the cold air discharged from the air hole 231 of the suction grille 23 is vertically discharged toward the wide surface of the beverage container 2 seated on the stirring member 50, that is, the side surface. Cooling efficiency of the beverage container 2 is best when the cold air discharged from the air hole 231 is perpendicular to the beverage container 2.

The stirring member 50 is provided inside the case 20, and is mounted to the stirring member support 25 formed on the bottom surface of the case 20. The stirring member 50 is mounted to swing left and right about the stirring member support 25 in the case 20, and is continuously connected to the driving assembly 40 to the left and right by a predetermined angle. It can be configured to rotate to stir the beverage in the beverage container (2). Detailed configuration of the stirring member will be described later.

In addition, the cooling unit may further include a drive assembly 40 for providing a driving force for the stirring member 50 to reciprocate in the left and right directions of the case 20 inside the case 20. have.

In addition, the fan motor assembly 30 includes a suction fan 31 for forcibly flowing air, a fan housing 32 mounted to the rear of the case 20 while accommodating the suction fan 31; It may be configured to include a fan motor 33 mounted to the rear of the fan housing 32 to provide a rotational force to the suction fan (31).

In detail, the suction fan 31 has a structure capable of sucking cold air generated in the evaporation chamber 107 with a strong suction force. When the suction fan 31 is used, the air flowing into the case 20 along the cold air flow path moves at a high speed toward the rear surface of the case 20 by a strong suction force. In addition, during the movement process, the heat exchanger is in contact with the outer circumferential surface of the beverage container 2 accommodated in the case 20. When the suction fan 31 that sucks air is used, the flow rate of the air is significantly faster than when the blower which blows air is used. This is because, when using the suction fan 31, the pressure difference between the front region and the rear region of the fan occurs in a shorter time. In addition, since the air flow rate is increased, the flow rate of air flowing per unit time increases, and as a result, the heat exchange amount between the beverage container 2 and the cold air increases. Therefore, there is an advantage that the heat exchange efficiency is better.

In addition, by using the suction fan 31, before the cold air sucked by the fan passes through the motor for driving the fan, the suction fan 31 exchanges heat with the beverage container 2 contained in the case 20. Therefore, the amount of heat exchange between the cold and the beverage container 2 is relatively increased, and the heat exchange efficiency is improved. If the blower is used, the air sucked by the blower passes through the fan motor for driving the blower and then heat exchanges with the beverage container 2. That is, the cold air sucked through the fan motor absorbs heat primarily, and then heats up with the beverage container 2. Therefore, the use of the suction fan 31 is more efficient than the case of using a blower heat exchange efficiency.

In addition, the suction fan 31 may be a centrifugal fan that sucks air in the axial direction and discharges it in the radial direction. The air passing through the case 20 generally flows in the horizontal direction, and a descending flow is required to return to the evaporation chamber 107. That is, the air flow direction when passing through the case 20 and the air flow direction after passing through the suction fan 31 cross each other. Therefore, it can be said that the centrifugal fan is appropriate in the case of the flow path in which the flow direction changes in the cross direction.

In addition, the suction fan 31 has an advantage of less flow resistance than the blower. For example, in the case of a blower for pushing air, if there is a narrow gap or obstacle in the air movement path, a phenomenon may occur that does not pass through the gap or obstacle and spreads or flows back. On the contrary, in the case of the suction fan 31, air is sucked in from the inlet of the fan to generate a pressure difference. Therefore, the air in front of the gap or obstacle has an advantage that can easily penetrate the gap by the pressure difference with the rear of the gap, and easily pass through the obstacle. As a result, when the suction fan 31 is used as compared to the blower under the same conditions, there is an advantage that the air flow resistance is low and the flow rate is high.

In addition, the suction fan 31 according to the embodiment of the present invention is one type of centrifugal fan, but there is a difference in structure with a conventional general centrifugal fan. In detail, the suction fan 31 has a disc shaped back plate 311, a blade 312 installed at the front of the back plate 311, and a suction guide placed on the top of the blade 312. 143. The blade 312 protrudes from the front surface of the back plate 311 with a predetermined width and extends in a round shape with a predetermined curvature in the radial direction from the center of the back plate 311. In addition, the suction guide 313 is characterized in that the functions of the existing bell mouth and orifice are performed in combination. That is, not only smoothly guides the intake of air from the front of the fan housing 32 into the suction fan 31, but also blocks the reverse flow of air discharged radially along the surface of the blade 312. Do this.

In detail, the suction guide 313 protrudes forward from the bottom of the circle, and protrudes in a shape of gradually decreasing in diameter. In other words, the longitudinal cross section of the suction guide 313 may have a structure in which the cross section diameter gradually decreases from the bottom portion to the top portion, and the cross section diameter is rounded at a certain point. As such, the outer circumferential surface of the suction guide 313 is rounded smoothly, thereby minimizing the flow resistance acting on the sucked air, thereby performing the function of the orifice. At the same time, by forming a tubular shape extending from the bottom of the suction guide 313 to a predetermined length, the bell mouse function is also possible to minimize the backflow of the air sucked through the inlet of the suction guide 313. Done. In addition, a grill 314 may be further formed in front of the suction guide 313 to prevent inhalation of foreign substances.

The cold air flow path unit may include a suction duct 11 for supplying the cool air generated in the evaporation chamber 107 to the case 20 and a return duct for discharging the cool air inside the case 20 to the freezing chamber 104. And (12). In detail, an inlet (or inlet) of the suction duct 11 may communicate with the evaporation chamber 107, and an outlet (or outlet) may be connected to the bottom of the case 20. In addition, an inlet of the return duct 12 may be connected to a bottom surface of the fan housing 32, and an outlet (or outlet) 121 may communicate with the freezing compartment 104. According to the embodiment shown in FIG. 2, the outlet 121 of the return duct 12 may be located at the rear side of the freezing compartment 104.
