[0008]

[0005] Refrigerators in recent years have tended to have large capacities, for example, by increasing the height of a vegetable compartment to allow storage of plastic bottles, beer bottles and the like in a vegetable case. There are restrictions on the height of the refrigerator due to the storage space of the refrigerator at home and the ease of use. Therefore, improvement in the utilization efficiency of the internal volume of the refrigerator is an essential technique to accommodate larger capacity, was also a challenge reduction of storage space <br/> evaporating dish in the evaporator.

However, in the conventional structure, the height of the storage space for the evaporating plate 10 is required in addition to the height of the legs 18 of the refrigerator, and the volume utilization efficiency of the lower portion of the refrigerator body 1 is poor. Further, the evaporation plate 10 when positioned below the lower end of the right and left side plates 2, as shown in FIG. 10, the evaporation plate 10 during transportation there is a problem such that breakage ride on the stepped portion.

[0010] The present invention has been made to solve the problems of the prior art, can be prevented effectively increase the internal volume available, yet the evaporator for transportation or the like are deformed or scratched It is intended to provide a refrigerator.

[0011]

SUMMARY OF THE INVENTION Accordingly, a refrigerator according to the present invention comprises a left and right side plate forming a side surface of a refrigerator, a pair of left and right side plate reinforcing members attached to lower ends of the left and right side plates, and a refrigerator connected to the left and right side plates. A bottom plate that closes the bottom of the refrigerator, and an evaporator disposed below the bottom plate, wherein the evaporator is disposed such that the lower surface thereof is positioned lower than the pair of left and right side plate reinforcing members, A length between the evaporator and the pair of left and right side plate reinforcing members that protrudes below the lower surface of the evaporator and corresponds to the length of the evaporator in the front-rear direction.
The above object is achieved by a configuration in which a pair of left and right bottom protection members are provided.

[0012]

By the action] above Ki構 formed, evaporator lower surface is located lower than the side plate reinforcing members than conventional can be located below, thus located below the bottom plate than conventionally positioned above the evaporator Therefore, when compared with a refrigerator having the same outer shape as that of the conventional refrigerator, the internal volume that can be effectively used can be increased as compared with that of the conventional refrigerator.

Moreover, the bottom protection members are provided on both the left and right sides of the evaporator so as to protrude below the lower surface of the evaporator .
Thus, it is possible to prevent the evaporator from being deformed or damaged during transportation or the like.
