The present invention relates to a detachable refrigerator that can be system-friendly. In particular, the refrigerator, the refrigerator, the evaporator and the main condenser are separated from the refrigerator and installed outdoors while the refrigerator is integrally installed at the bottom of the sink. The present invention relates to a separate refrigerator that is ejected through a rear upper part to cool an interior of a kitchen or the like.

The conventional integrated refrigerator includes a main condenser 10, a condensation preventing pipe 11 and an auxiliary condenser 12, as shown in FIG. That is, the main condenser 10 is arranged in a zigzag shape over the entire left and right sides of the frame back plate 13 or the cabinet 14 of the refrigerator 1, and then the aluminum tape is attached to the heat insulating member 15. It has been installed on the side wall.

The condensation prevention pipe 11 has been embedded in the outer periphery of the flange of the front of the refrigerator 1 to prevent dew formation.

The auxiliary condenser 12 has been installed at the bottom of the evaporation plate 16 to evaporate the defrost water collected in one place.

Referring to the operation of the integrated refrigerator having such a configuration, when the compressor 17 mounted at the bottom of the refrigerator 1 starts operation to reach a temperature set in the refrigerator, the high-temperature and high-pressure gas refrigerant is the auxiliary condenser 12, the main condenser. 10 and the condensation prevention pipe 11 are converted into liquid at high temperature and liquefied while passing sequentially, and are cooled by being expanded while passing through the evaporator 19 under reduced pressure through a capillary tube (not shown).

(13) or the cabinet (14) has a structure that is installed in a zigzag shape on the entire left and right sides, but in this natural cooling system, the heat of condensation generated in the main condenser 10 is refrigerated and refrigerating through the insulating member (15). (23) (24) As it penetrates inside, it lowers the efficiency of freezing and refrigerating and at the same time increases the freezing load. In addition, the ambient temperature of the room is increased by the heat of condensation, and the operating time of the compressor 17 is extended. There was a problem that increases the power consumption.

In addition, since the compressor 17 is installed in the lower part of the refrigerator 1, the heat of compression generated when the compressor 17 is operated is conducted to the room, thereby raising the ambient temperature, as well as in the compressor 17. There was also a problem that the generated vibration noise is transmitted directly to the room.

Accordingly, the present invention has been made to solve the above problems, and the object of the present invention is to improve the compression and condensation efficiency and at the same time to improve the freezing and refrigeration efficiency, the compressor, compression and condensation heat and noise transfer and conduction to the room At the same time, the inside of the refrigerator can be used widely, and a part of the cold air is blown out through the sink to provide a separate refrigerator that can cool the interior of the kitchen.
