Description

Refrigerator with draw-out cooling unit {Refrigerator with a withdrawable cooling unit}

The present invention relates to a refrigerator provided with a draw-out cooling unit, and more particularly, a drawer-type cooling unit having a new structure provided to be able to pull out only the cooling unit separately as well as being integrally provided with a cooling unit including an evaporator. It is about an old refrigerator.

In general, the refrigerator keeps the interior of the refrigerator at a low temperature by exchanging heat while the refrigerant is circulated by lowering the temperature in the refrigerator by the refrigeration cycle. The unit forming the refrigeration cycle is composed of a compressor, a condenser, an expansion valve, and an evaporator interconnected by a refrigerant pipe. As an example of such a refrigerator, a table-type refrigerator generally used in a shop or the like will be described with reference to the drawings. Same as

As shown in FIG. 1, the conventional table-type refrigerator 10 includes a table 12 that can be used as a worktop or the like on the upper surface of the main body frame 11, and a lower portion of the table 12 has refrigerant on one side thereof. A mechanical chamber 13 in which a compressor 15 and a condenser 16, etc., which are interconnected by pipes is built, is formed, and a refrigerating chamber 14 is formed at one side of the mechanical chamber 13 to store food and the like. One side is partitioned in the refrigerating compartment 14 and an evaporator 17 connected to the compressor 15 and the condenser 16 by a refrigerant pipe, and a motor for blowing cool air by the evaporator 17 to the refrigerating compartment 14. 18 and a blower fan 19 coupled thereto are located.

However, such a conventional refrigerator 10 has a compressor in which an evaporator 17 and a blowing fan 19 for supplying cold air are respectively installed on one side of the refrigerating chamber 14 as well as built in the machine room 13. 15) and the condenser 16 are separately mounted to the body frame 11, the installation and detachment of the device is very cumbersome, and this leads to inconvenience in manufacturing and maintenance.

In addition, since the refrigerator 10 has a configuration such that the evaporator 17 and the blower fan 19 are partitioned on one side of the refrigerating compartment 14, the internal volume of the refrigerating compartment 14 is reduced to a sufficient amount. Difficulties in storing the object to be stored.

The present invention is to solve the problems as described above, the present invention is provided with a cooling unit including the evaporator is integrally provided as well as to be able to pull out only this cooling unit separately, and the configuration other than the cooling unit is on the pedestal It is provided in the unit can be pulled out integrally to provide convenience in installation and maintenance, and a refrigerator with a draw-out type cooling unit of a new structure that can increase the internal volume of the refrigerating chamber as the cooling unit is arranged in the machine room To provide.
