The heat dissipation fan 83 may be installed above the condenser 80 or below the compressor 84 . A condenser 80 is positioned above the heat dissipation fan 83 according to an embodiment of the present invention, and a compressor 84 is positioned below the heat dissipation fan 83 . Accordingly, since an air flow from the lower side of the electronic unit 60 to the upper side is generated by the operation of the heat dissipation fan 83, the compressor 84 and the condenser 80 can be cooled quickly.

The evaporator 86 protrudes to the inside of the display unit 10, receives the refrigerant that has passed through the condenser 80, and exchanges heat with the air inside the display unit 10.

Since the condenser 80, the heat radiation fan 83, the compressor 84, and the evaporator 86 constituting the refrigeration system 70 are vertically arranged, the space in which the refrigeration system 70 is installed can be minimized. . In addition, by operating the refrigeration system 70 , the inside temperature of the display unit 10 may be maintained at 8° C. to 10° C.

In addition, in order to install the refrigeration system 70 in a relatively narrow space, each part of the refrigeration system 70 is installed with a high-efficiency product.

A spiral pin is applied to the evaporator 86 to increase a heat exchange area. And since the refrigeration system 70 is arranged in a vertical direction, there is a risk that the upright refrigerating storage device 1 is overturned. Therefore, in order to lower the center of gravity of the upright refrigeration storage device 1 as much as possible, the compressor 84 is located on the lower side, and the heavy support 130 is also installed on the lower side of the electric unit 60.

The electrical body 100 is a cylindrical case extending in the vertical direction, and is provided with an inlet 110 and an outlet 120, respectively.

The inlet 110 forms a passage through which air is introduced on the side of the electrical body 100 facing the compressor 84 . The inlet portion 110 forms a plurality of holes along the circumference of the electrical body 100 .

The outlet part forms a passage through which the air passing through the condenser 80 is discharged to the outside of the electric body 100 . The outlet is located above the inlet 110 and forms a plurality of holes along the circumference of the electrical body 100 .

The air introduced into the inside of the electric body 100 through the inlet 110 passes through the compressor 84, the heat dissipation fan 83, and the condenser 80 in order, and then passes through the discharge part 120 to the electric body 100. ) is discharged to the outside of the In addition, the air discharged to the outside of the electric body 100 moves upward along the outside of the display unit 10 and removes moisture on the outside of the display unit 10 .

In the upright refrigeration storage device 1 according to an embodiment of the present invention, the radial center of the display unit 10 and the radial center of the electric unit 60 are located on the same vertical line. That is, since the radial centers of the display unit 10, the electric unit 60, and the support unit 130 are located on the same vertical line, the space occupied by the upright refrigeration storage device 1 can be minimized and space utilization can be increased. there is.

Also, the radial center of the display unit 10 and the radial center of the evaporator 86 are located on the same vertical line. Accordingly, since the air passing through the evaporator 86 can more easily diffuse into the display unit 10, cooling efficiency can be improved.

According to an embodiment of the present invention, the display unit 10 has a cylindrical shape, the support unit 130 has a disk shape, and the outer diameter D3 of the support unit 130 is greater than the outer diameter D1 of the display unit 10. have Therefore, since the upright refrigeration storage device 1 is supported more stably, it is possible to reduce the risk of a safety accident due to overturning.

As shown in FIGS. 8 and 9 , when the refrigeration system 70 installed in the electronic unit 60 is operated, refrigerant is supplied to the evaporator 86 installed inside the display unit 10 . The air around the evaporator 86 is cooled by the refrigerant passing through the evaporator 86 .

When the drive motor 90 installed inside the evaporator 86 is operated, the output shaft 92 of the drive motor 90 rotates. A fan member 94 connected to the output shaft 92 rotates together with the output shaft 92 to induce circulation of air.

Therefore, the air inside the display unit 10 is moved to the inside of the projecting case 96 through the side of the projecting case 96, exchanges heat with the evaporator 86, and passes through the hollow of the support cover 88 to the projecting case ( 96) to the upper side. In addition, the airflow passing through the shelf 40 and moving to the upper side of the display body 20 lowers the internal temperature of the display unit 10 to a set temperature.

Cool air generated in the evaporator 86 is maintained by rotation of the fan member 94 using a box fan to form an air flow forcibly circulating the inside of the display unit 10 .

As described above, since the evaporator 86 is located inside the exhibition unit 10, the cooling efficiency can be improved by shortening the heat exchange time of the cold air generated in the refrigeration system 70 with the air inside the exhibition space.

(80) is sequentially cooled and discharged to the outside of the electrical body (100) through the inlet (110). Since the compressor 84 and the condenser 80 can be simultaneously cooled by the operation of the radiating fins, electricity usage fees can be reduced.

As the air discharged from the electronic unit 60 moves upward along the outer surface of the display unit 10 , condensation on the outside of the display unit 10 may be prevented.

A cooling pack may be installed inside the display unit 10 in which the evaporator 86 is installed. The evaporator 86 of the refrigeration system 70 and the cold storage pack may be installed, and various modifications such as only the cold storage pack may be installed.

A cold storage pack is installed instead of the evaporator 86, and when the door unit 30 is manually opened, since a separate power supply is not required, the upright refrigerator 1 can give an impression like a real piece of furniture.

Meanwhile, defrost water generated in the evaporator 86 is collected in the tray unit 50 , and the water collected in the tray unit 50 may be evaporated by heat generated in the condenser 80 .

In addition, the high-temperature wind discharged from the discharge unit 120 moves upward along the outer surface of the display unit 10 and dew formation on the outside of the display unit 10 can be prevented. Meanwhile, a dew formation prevention function may be added by additionally installing a heating wire on the outer surface of the display unit 10 to prevent dew formation.

As described above, the present invention has been described with reference to the drawings illustrated, but the present invention is not limited by the embodiments and drawings disclosed in this specification, and various modifications are made by those skilled in the art within the scope of the technical idea of the present invention. It is obvious that variations can be made.
