An open lower surface of the case 100 is provided with a connection member 160 for connecting the case 100 and the drive unit case 200 in which the drive unit 250 is accommodated. The connecting member 160 forms a flow path such that air discharged downward of the case 100 is directed to the drive unit case 200, and is formed in a funnel shape in which the diameter of the cross section is narrowed downward. The upper and lower ends are opened to be connected to the case 100 and the driving unit case 200, respectively.

Therefore, the cold air passing through the case 100 is discharged to face the center of the drive unit case 200 so that suction to the suction fan 240 to be described below can be made smoothly.

The drive unit case 200 is formed to be mounted to the drive unit 250 and the suction fan 240, and forms a flow path for guiding the cold air passed through the case 100 and the connecting member 160 downward. Configured to do so.

Is formed. The opened portion of the suction fan accommodating part 210 corresponds to the center portion of the suction fan 240 and allows cold air to be smoothly sucked into the suction fan 240.

On the other hand, the suction fan 240 is configured to suck the cold air generated in the heat exchange chamber 50 with a strong suction force. The suction fan 240 allows the air introduced into the case 100 along the suction duct 60 to move to the lower surface of the case 100 at a high speed 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 B accommodated in the case 100. When the suction fan 240 that sucks air is used, the flow rate of the air is significantly faster than when the blower that blows air is used. This is because, when using the suction fan 240, 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 air flow rate per unit time increases, and as a result, the heat exchange amount between the beverage container B and the cold air increases. Therefore, there is an advantage that the heat exchange efficiency is better.

In addition, the suction fan 240 is used, so that the cold air sucked by the fan exchanges heat with the beverage container B housed inside the case 100 before the heat exchange with the driving unit for driving the fan. do. Therefore, the heat exchange amount between the cold and the beverage container (B) is relatively increased, there is an advantage that 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 (B). That is, the cold air sucked through the fan motor absorbs heat primarily, and then heats up with the beverage container (B). Therefore, the use of the suction fan 240 has the advantage that the heat exchange efficiency is improved compared to the case of using the blower.

In addition, the suction fan 240 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 240, a pressure difference is generated by sucking air from the inlet of the fan. 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 240 is used as compared to the blower under the same conditions, there is an advantage of low air flow resistance and a large flow rate.

The blade 244 protrudes from the front surface of the back plate 242 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 242. In addition, the suction guide 246 is characterized in that the functions of the existing bell mouth and orifice are combined. That is, the suction fan 240 not only smoothly guides the intake of air into the suction fan 240 but also functions to block the reverse flow of air discharged in the radial direction along the surface of the blade 154.

In detail, the suction guide 246 protrudes forward from the circular bottom portion, and protrudes in a form of gradually decreasing diameter. In other words, the longitudinal cross section of the suction guide 246 may have a structure in which the cross sectional diameter gradually decreases from the bottom to the upper end, and then rounds in such a manner that the cross sectional diameter is kept constant at a certain point. As such, the outer circumferential surface of the suction guide 246 is smoothly rounded to minimize the flow resistance acting on the suctioned 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 246 to a predetermined length, the bell mouse function may be performed to minimize the backflow of the air sucked through the inlet of the suction guide 246.

Hereinafter, the cooling device 300 will be described in more detail with reference to the accompanying drawings.

10 is a perspective view of the cooling device. 11 is an exploded perspective view of the cooling device. And, Figure 12 is a view showing a state inside the case of the cooling device is open.

10 to 12, the cooling device 300 includes a case 400 in which a beverage container B is accommodated, a driving unit 640 provided at one side of the case 400, and the driving unit ( The suction fan 630 rotated by the 640 and the rotation fan 510 rotated by the flow of cold air by the suction fan 630 may be configured to include.

Looking at this in more detail, the case 400 is a case main body 410 to form the majority of the space for accommodating the beverage container (B), and a case for selectively shielding the open upper surface of the case body 410 It may be configured as a cover 420.

The case body 410 is formed in a rectangular parallelepiped shape formed so that an upper surface thereof is opened, and the opened upper end is formed to be inclined. The case body 410 is configured to slide in and out forward in a state where the cooling device 300 is mounted in the refrigerating chamber 30.

On the other hand, the inside of the case body 410 is provided at a position in which the rotating roller 430 and the support roller 440 is separated. The rotating roller 430 and the support roller 440 extend long inside the case body 410, and are rotatably mounted by support parts 432 and 442 mounted on the bottom of the case body 410, respectively. And, the beverage container (B) is seated between the rotary roller 430 and the support roller 440, the outer surface of the beverage container (B) is the rotary roller 430 and the support roller 440 and You will come across.

The rotating roller 430 is a part of the rotating shaft 434 penetrates through the support parts 432 and 442 and penetrates through one side surface (left side in FIG. 11) of the case body 410 to protrude outward. In addition, the rotating shaft 434 of the rotating roller 430 is coupled to the rotating fan 510 on the outside of the case body 410.

Therefore, the rotary roller 430 rotates when the rotary fan 510 rotates, and the beverage container B which is in contact with the rotary roller 430 may also rotate by the rotation of the rotary roller 430. Will be. In addition, when the beverage container B rotates, the support roller 440 contacting the beverage container B also rotates. Therefore, the liquid in the beverage container (B) can be stirred evenly.

In addition, an inside of the case body 410 is provided with a discharge guide member 450 for guiding the air discharge in the case body 410. The discharge guide member 450 is formed along the longitudinal direction of the case body 410, and is formed at the bottom edge of the case body 410, which is a position opposite to the cover plate 424 to be described below. The discharge guide member 450 extends to an opening at one side of the case body 410 and is configured to communicate with the rotating fan cover 500 to be described below. In addition, a plurality of discharge ports 452 are formed in the case body 410 at regular intervals along the longitudinal direction. The discharge port 452 is formed by forming a slit, and is formed over the upper surface and the side surface of the discharge guide member 450.

A rotating fan cover 500 is provided on one side (left side in FIG. 11) of the case body 410 in which the opening is formed. The rotary fan cover 500 is mounted to the case body 410 and is formed to form an accommodation space of the rotary fan 510 and a flow path of cold air.

In detail, the rotating fan cover 500 has one surface opened to form a space therein so that the rotating fan 510 may be mounted. In addition, the flow guide 520 is formed on the rotating fan cover 500. The flow guide 520 partitions the rotary fan cover 500 so that cold air introduced through the discharge guide member 450 may flow into the suction fan 630 via the rotary fan 510. You will be guided.

In addition, an outlet 530 is formed on an upper surface of the rotating fan cover 500. The connection member 540 is formed at the outlet 530. The connection member 540 guides the cold air discharged from the rotary fan cover 500 toward the suction fan 630. The connection member 540 is formed to be connected to the rotating fan cover 500 and the driving unit case 600 by opening the lower surface and the rear surface.

The drive unit case 600 is formed to be mounted to the drive unit 640 and the suction fan 630, and forms a flow path for guiding the cold air passed through the case 400 and the connection member 540 downward. Configured to do so.

The driving unit case 600 may include a suction fan accommodating part 610 in which the suction fan 630 is accommodated therein and a driving unit mounting part 620 in which the driving unit 640 is provided.

In more detail, the suction fan accommodating part 610 is formed in a shape corresponding to the suction fan 630 to accommodate the upper surface of the suction fan accommodating part 610 so as to have an opening corresponding to an outlet side of the connection member 540. Is formed. The opened portion of the suction fan accommodating part 610 corresponds to the center portion of the suction fan 630 and allows the cold air to be smoothly sucked into the suction fan 630.

On the other hand, the suction fan 630 is configured to suck the cold air generated in the heat exchange chamber 50 with a strong suction force. The suction fan 630 moves the air flowing into the case 400 along the suction duct 64 at a high speed toward the bottom surface of the case 400 by a strong suction force. In addition, during the movement, heat exchange is performed while contacting the outer circumferential surface of the beverage container B accommodated in the case 400. When the suction fan 630 that sucks air is used, the flow velocity of the air is significantly faster than when a blower for blowing air is used. This is because, when using the suction fan 630, 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 and the cold air increases. Therefore, there is an advantage that the heat exchange efficiency is better.

In addition, the suction fan 630 is used, so that the cold air sucked by the fan exchanges heat with the beverage container B accommodated inside the case 400 primarily before the heat exchange with the driving unit 640 for driving the fan. Will be Therefore, the heat exchange amount between the cold and the beverage container is relatively increased, thereby improving the heat exchange efficiency. 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 (B). That is, the cold air sucked through the fan motor absorbs heat primarily, and then heats up with the beverage container (B). Therefore, the use of the suction fan 630 has the advantage that the heat exchange efficiency is improved compared to the case of using the blower.

In addition, the suction fan 630 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 630, a pressure difference is generated by sucking air from the inlet of the fan. 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 is used as compared to the blower under the same conditions, the air flow resistance and the flow rate are high.

In addition, the suction fan 630 according to an embodiment of the present invention is one type of centrifugal fan, but there is a difference in the structure of the existing general centrifugal fan. In detail, the suction fan 630 includes a disc plate back plate 632, a blade 634 installed on the front surface of the back plate 632, and a suction guide placed on an upper end of the blade 634. 636. The blade 634 protrudes from the front surface of the back plate 632 to have a predetermined width and extends from the center of the back plate 632 to be rounded with a predetermined curvature in the radial direction. In addition, the suction guide 636 is characterized in that the function of the existing bell mouth (orifice) is performed in combination. That is, the suction fan 630 smoothly guides the suction of air, and serves to block the reverse flow of air discharged in the radial direction along the surface of the blade 634.

In detail, the suction guide 636 protrudes forward from the circular bottom portion, and protrudes in a form of gradually decreasing diameter. In other words, the longitudinal cross section of the suction guide 636 may have a structure in which the cross section diameter gradually decreases from the bottom to the top end, and then rounds in a form in which the cross section diameter is kept constant at a certain point. As such, the outer circumferential surface of the suction guide 636 is smoothly rounded to minimize 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 636 to a predetermined length, the bell mouse function can also be performed to minimize the backflow of the air sucked through the inlet of the suction guide 636. Done.

On the other hand, the driving unit mounting portion 620 is formed on the rear side of the suction fan receiving portion 610. The drive unit mounting part 620 is formed to accommodate at least a portion of the drive unit 640 therein.

The driving unit 640 may be configured like a general electric motor, and may be fixedly mounted in the driving unit mounting part 620.

In addition, the driving unit case 600 is formed so that the rear surface is opened so that the cold air discharged by the suction fan 630 can be moved to the rear. In addition, the driving unit case 600 may be accommodated in the duct connecting member 650 and is connected to the return duct 74 by the duct connecting member 650 to be discharged from the driving unit case 600. It is configured to allow cold air to flow into the return duct (74).

On the other hand, the case cover 420 is formed so that the lower surface is opened, the lower end is formed to have a slope corresponding to the upper end of the case body 410. Therefore, the case cover 420 is configured to open and close the case body 410 while the case body 410 is pulled in and out.

The rear end of the case cover 420 is formed with a suction duct connecting portion 422 protruding rearward. The suction duct connection part 422 is connected to the suction duct 64, and is formed to communicate the inside of the case cover 420 with the suction duct 64.

In addition, a cover plate 424 is formed inside the case cover 420. The cover plate 424 is provided on the case cover 420 and forms a predetermined space in the case cover 420. In addition, the space formed by the case cover 420 is configured to communicate with the suction duct connection part 422 so that the air sucked through the suction duct 64 may be introduced therein.

The cover plate 424 may be formed at a corner side of the case cover 420 facing the discharge guide member 450, and may be disposed to be inclined or to have a round surface.

In addition, a plurality of air holes 426 are formed in the cover plate 424. The air hole 426 is opened to face the discharge guide member 450 side, is disposed along the longitudinal direction of the beverage container (B) is discharged vertically toward the beverage container (B).

Hereinafter, the operation of the refrigerator according to another embodiment of the present invention having the configuration as described above will be described.

In order to quickly cool the beverage or liquor at room temperature, first, the case body 410 is pulled forward, and then the beverage container B is placed inside the case body 410. At this time, the beverage container (B) is seated between the rotating roller 430 and the support roller 440. Therefore, the beverage container B is in a state of being in contact with the rotary roller 430 and the support roller 440 in a state accommodated inside the case 400.

After the drink container B is inserted, when the case body 410 is inserted, the case body 410 is shielded by the case cover 420. Then, after closing the refrigerating compartment door 22, the operation for the operation of the cooling device 300 is performed.

When the operation signal of the cooling device 300 is input, the driving unit 640 is operated. The suction fan 630 is rotated by the operation of the driving unit 640. By the rotation of the suction fan 630, the suction fan 630 generates a strong suction force.

The cool air generated in the evaporator 52 by the suction force of the suction fan 630 is introduced into the case 400 through the suction duct 64 connected to the heat exchange chamber 50. The cold air flowing into the case 400 is introduced into the case cover 420 through the suction duct connection part 422 and is discharged toward the beverage container B through the air hole 426. . At this time, the cold air discharged through the air hole 426 is discharged to be in contact with the side of the beverage container (B) perpendicularly, and discharged at the shortest distance toward the discharge guide member 450, the beverage container (B) Heat exchange with.

Therefore, the cold air inside the case 400 moves through the blade 634 of the rotary fan 510 to the suction fan 630, whereby pressure is applied to the blade 634 by the flow of cold air. The rotating fan 510 is rotated.

When the rotating fan 510 rotates, the rotating shaft 434 of the rotating roller 430 connected to the center of rotation of the rotating fan 510 is rotated so that the rotating roller 430 may be rotated at the same time. In addition, the beverage container B also rotates as the rotary roller 430 rotates. Therefore, the cold air introduced into the case 400 can cool the outer side surface of the beverage container B evenly. In addition, the liquid inside the beverage container B may also be stirred as the beverage container B rotates, and the liquid at a position in contact with the outer surface of the beverage container B may be rapidly cooled. Therefore, the beverage container B inside the case 400 may be rapidly cooled by cold air introduced while rotating.

The cold air passing through the rotary fan 510 is moved toward the center of the suction fan 630 through the connecting member 540, and the cold air sucked into the center of the suction fan 630 is the suction fan. 630 is discharged in the radial direction. The discharged cold air moves backward along the inner surface of the drive unit case 600.
