      The present invention relates to a refrigerator, and more particularly to a refrigerator having an improved structure in which an evaporator is assembled into an inner phase.

      The refrigerator is a device for supplying the cold air generated by the refrigeration cycle to the storage compartment to maintain the freshness of various foods for a long time. In general, a refrigerator includes a compressor, a condenser, an expansion valve, and an evaporator to supply cold air to a storage compartment by using heat transfer due to a phase change of the refrigerant. Of these, the evaporator receives the heat required for evaporation of the refrigerant from the ambient air to lower the temperature of the ambient air to generate cold air supplied to the storage compartment, and is generally disposed at the rear of the storage compartment and fixed to the inside of the refrigerator.

      1 is a perspective view showing a conventional evaporator assembly structure, Figure 2 is a cross-sectional view taken along the line I-I when the evaporator is assembled in the interior in Figure 1; As shown in FIGS. 1 and 2, the evaporator 1 is fixed to the inner bed 3 via a screw 2. To this end, both sides of the evaporator 1 are provided with an evaporator side plate 4 including a screw fixing part 4a, and an inner cavity 3 is provided with a coupling hole 3a for inserting the screw 2 therein. In addition, a screw grommet (5) is inserted and installed in the coupling hole (3a), in which the screw (2) is foamed between the inner (3) and the inner (3) and the outer (6) of a thin plate. If it is inserted into (7) as it does not maintain the proper assembly strength is to compensate for this point so that the evaporator (1) can be firmly coupled to the inner phase (3).

      However, in the conventional evaporator assembly structure as described above, as the coupling hole 3a for inserting the screw 2 into the inner phase 3 is formed, the moisture in the cooling chamber 8 is transferred to the inner phase 3 through the coupling hole 3a. It is penetrated to the rear of the, thereby causing cracks in the heat insulating material 7 formed between the inner wound (3) and the outer wound (6) there is a problem that the heat insulating performance of the heat insulating material (7) is lowered. Particularly, in the case of the freezing chamber, since the freezing process and the defrosting process are periodically repeated with a large temperature difference, the size of the coupling hole 3a is increased by thermal expansion during defrosting, whereby a large amount of moisture is generated in the inner phase 2. As it penetrates backwards, the above problem is further exacerbated.

      In addition, the conventional evaporator assembly structure has a structure in which a constant space can be generated between both sides of the evaporator 1 and the inner bed 3 when the evaporator 1 is fixed to the inner bed 3, There is a problem that the cooling efficiency is lowered. That is, some of the air passing through the evaporator 1 passes through a space formed between both sides of the evaporator 1 and the inner bed 3, and this part of the air does not properly heat exchange with the evaporator 1, but the evaporator does not properly exchange heat. Since passing through (1) will reduce the cooling efficiency of the evaporator (1).

      In addition, the conventional evaporator assembly structure requires a process such as inserting the screw grommet 5 into the coupling hole 3a or aligning the hole of the screw fixing part 4a with the position of the coupling hole 3a. Since it takes a lot, there is a problem that the productivity of the product is lowered.
