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. 10 Other objects are to provide separate compartments for the storage and preservation of foods l 2 with certain parts either omitted or broken away to show the underlying structure. Figure 4 is a fragmentary view of the shutter device shown in Figures 2 and 3, with the shutter closed and with parts broken away to show the underlying structure. Figure 5 is a fragmentary section taken along line 5-5 of Figure 3. Figure 6 is a section along line 6-6 of Figure `4.

The primary evaporator I4 in compartment A is of relatively large capacity‘and iszadapted'for the storage of meats' and frozen foods as well as for ice-making. In Athe exemplary embodiment the evaporator is mounted to one side of the cabi egress of air between the compartments A and B and may be utilized to maintain a normal degree of Vmoisture during excessively humid weather. [During such periods,7„the shutter‘pslide may be `~conveniently adjusted to‘ a partial 4or full open position to permit a movement of air between 'i the compartments. Any such movement tends to net with the shelves I5 and I6 alongside the evap orator, supported on one side by a plurality of studs screwed into the wall of the compartment. The opposite sides of the shelves are supported « by a pair of L-shaped brackets extending about the side and bottom of the evaporator and secured to the top and side wall of ythe »cabinet preferably by screws and as shown in‘our copending appli cation Serial No. 422,422, filed December 10, 1941. The shelves I5 and I6 rest upon angular lugs, secured to the respective brackets, and the shelves cause a partial dehydration of the air in corn partment B.v The shutter adjustment is likewise >of utility in maintaining proper humidity for _various kinds of foodstuffs. It is to be noted that when there is a temperature diiïerential be tween the two compartments there will be some actual circulation of air therebetween, butwhen _ the temperature within the compartments is the same the movement of air will be derived from the difference in vapor pressure between thecom- _ partments and will be of small magnitude.. The forward edge of the shelf I1 is provided may if desired, be heldin place by means of studs 20 with a resilient sealing strip. The strip 43, screwed into the brackets above the shelves, clamped within a groove formed along the edge which, in conjunction with depending pins at the of the frame |112,V is preferably of rubber for front and rear, prevent removal of the shelves. making a sealing union with _the door shelf A21c Heat is absorbed from compartment B by a -secondary evaporator 3I insulated> from the wall 25 when the door is closed.

When not in use, the racks may be folded flat on the bottom of the shelf. ` on the ~outer bottom edge of the refrigerator. The refrigerator mechanism is preferably placed well back of the lower compartment in order to leave space for a vegetable bin formed integrally with a cover or door 86.
