This invention relates to refrigerators, and is
` particularly concerned with cabinets and mechanisms for refrigerators of the household type.
The invention will be described in connection
with an electric refrigerator of the compression- 5
expansion type, but is not limited thereto.
An object of the invention is to provide ahousehold refrigerator which is simple in design, economical to manufacture, convenient and accessible to the user, and efficient in operation.
Other objects are to provide separate compartments for the storage and preservation of foods l
with certain parts either omitted or broken away
to show the underlying structure.

device shown in Figures 2 and 3, with the shutter
closed and with parts broken away to show the
underlying structure.
