As described above, the auxiliary condenser 60 may be provided in one line type to facilitate an assembly operation. Next, a process of assembling the auxiliary condenser 60 in the cabinet 10 of the parallel refrigerator will be described.

First, in the assembling process of the cabinet 10, the first partition wall embedding portion 61A of the auxiliary condenser 60 is inserted into the freezing chamber interior 12 at the insertion portion 13A of the refrigerating compartment interior 13 on the side of the intermediate partition 14. After arranging the third bulkhead buried portion 61C of the sub-condenser 60 in the insertion portion 12A of the sub-condenser, respectively, the refrigerator compartment internal image is placed on the one pocket portion 14C and the other pocket portion 14D of the cover 14B, respectively. When the insertion portion 13A of the 13 and the insertion portion 12A of the freezer compartment 12 are squeezed through the rubber hammer, the freezer compartment 12 and the refrigerator compartment interior 13 are sealed by the cover 14B. do. At this time, the second bulkhead buried portion 61B is formed between the pocket portions 14C and 14D of the cover 14B, that is, the insertion portion 13A of the refrigerating chamber image 13 and the insertion portion 12A of the freezing chamber image 12. Are arranged side by side, and as described above, they are bent inward from the first bulkhead buried portion 61A and the third bulkhead buried portion 61C, and thus the first and second bulkhead buried portions 61A and 61B. ) Is not disturbed during assembly. The edge embedding portion 62 extending from the third partition wall embedding portion 61C is disposed along the edge portion of the freezer compartment inner image 12, and then the end portion is positioned inside the machine chamber 15.

In this state, the outer box 11 is assembled to enclose the freezer compartment 12 and the refrigerating compartment 13, and when urethane foam is injected into these gaps, an insulation wall (12) is formed between the freezer compartment 12 and the refrigerating compartment 13. 14A) is formed, the cover 14B, the freezer compartment 12 and the refrigerator compartment 12 are firmly fixed. Therefore, the auxiliary condenser 60 disposed on the edge portion of the freezer compartment interior 12 and the intermediate partition 14 is also embedded in the heat insulating wall 14A. In particular, the foam liquid is also injected into the pocket portions 14C and 14D of the cover 14B constituting the intermediate partition 14, whereby the partition buried portion 61 of the auxiliary condenser 60 bent and arranged in three stages is formed. It remains more firmly fixed.

Then, one end of the auxiliary condenser 60 extending to the machine room 15 is welded to the main condenser 16 and the other end is welded to the expansion means so that the refrigeration cycle is made of a closed circuit. At this time, since the auxiliary condenser 60 is composed of one line type as described above, the assembly operation thereof is easily performed. In other words, the welding location is reduced by half compared to the conventional two-line auxiliary condenser, the assembly workability is significantly improved.

Next will be described the operation and effect of the auxiliary condenser according to the present invention.

First, when the left door 40L and the right door 40R are closed, the gasket 41 is in close contact with the cover 14B through the magnet 42 to seal the freezing chamber 20 and the refrigerating chamber 30.

And the high temperature and high pressure refrigerant discharged from the compressor is condensed primarily through the main condenser 16, and then condensed secondly while passing through the auxiliary condenser 60 embedded in the front of the cabinet (10). The condensed refrigerant evaporates in the evaporator and then returns to the compressor.

At this time, the front surface of the cover 14B and the cabinet 10 are heated by the refrigerant condensed while passing through the auxiliary condenser 60, thereby preventing dew formation. In particular, since the auxiliary condenser 60 is buried only along the edges of the intermediate partition 14 and the freezer interior 12 through the partition buried portion 61 and the edge buried portion 62 bent in three stages, Most of the heat transferred from the auxiliary condenser 60 is locally discharged through the front surface of the cabinet 10 on the side of the freezer compartment 20 in which a large temperature difference occurs, and thus dew condensation is more effectively prevented.

In addition, since the auxiliary condenser 60 is not provided at the side wall edge portion of the refrigerating chamber 30 side in which the temperature difference is kept relatively small, the heat of condensation of the auxiliary condenser 60 is not transmitted to the refrigerating chamber 30 side. As a result, the heat exchange efficiency of the refrigerating chamber 30 is improved.

As described in detail above, according to the cabinet of the parallel refrigerator having a sub-condenser according to the present invention, the sub-condenser is composed of one line, the intermediate portion partitioning the freezer compartment and the refrigerating compartment and the edge portion in the freezer compartment forming the freezer compartment Since it is only buried locally, there is an advantage that the assembly workability of the auxiliary condenser is improved and its manufacturing cost is further reduced. In addition, since the secondary condenser is not installed on the front of the refrigerating chamber side where the temperature difference between the outside air is kept smaller than that of the freezing chamber, and condensation does not occur, the heat exchange efficiency of the refrigerating chamber is further improved because the condensation heat of the secondary condenser is not transferred to the refrigerating chamber. There is an advantage.
