It is therefore the main object of the invention to divide the refrigerator into two' compartments so as to separate the foods which are used more commonly from the other foods.v

Some foods, as we known, desire a lower temperature than others to keep them fresh and healthful. It is therefore another object of the invention to I provide a separate compartment having a lower temperature than the rest of the refrigerator where such foods can be stored.

- Again some foods have certain distinctive odors or. flavors which, when allowed to reach other foods, are apt to have deleterious effects on them. It is therefore a third object of the invention to provide two compartments with a wall separating said compartments so the scent, savor or flavor given oi! from the food in one compartment will not reach the other compartment.

In the present refrigerators, when the door is opened the warm air from the room completely fills the interior of the refrigerator therebycausing a loss in its efiiciency and besides places an extra burden on the refri erating machinery in order to chill the warm air which entered. In

' order to lessen this loss of efficiency it is a fourth 'to limit the invention to the embodiment illusappended claims. v

Figure 5 is a modified form of a partial vertical section of the front of the refrigerator and Figure 6 is another modified form of apartial vertical section of the front of the refrigerator.

Referring'now to the drawings in detail, numeral i designates the cabinet. 2 the outer shell of the refrigerator preferably made of sheet metal and IA the innerishell of the cabinet. Between the inner and outer shells is the insulation 1. Numeral I represents an auxiliary door made of two walls of sheet metal with the insulatin medium I between them. Said door fits in the composition or the equivalent to which said walls are united to avoid an all metal path for the conduction of heat into the refrigerator which would greatly decrease the eiilciency thereof.

The main door! is moimted on the hinges ii which are fastened to the front wall of the refillerator cabinet I.

' InFigureSisshownanotherwaytooooi the auxiliary compartment which consists of causing a circulation of air in a vertical plane by providing slots in the top and bottom of the wall 2 A for the air ,to'circulate by. The slots I at the top are formed by bending a portion of the metallic wall inwardly towards the evaporator as at 5'. This bent portion will cause the stream of air to form a downwardly vertical path on entering the compartment. As the cold air is heavier ,than the warm air; the cold air will drop towards the bottom and on being warmed it will pass out to the main compartment by the way of the openings s'.

. In Figure 6 is shown a third and direct method of cooling the auxiliary compartment. This method consists of providing an opening 8' in the wall 2A of the auflliary compartment for allowing the forward end of the evaporator to enter therein. when the main door is closed as shown in this figure the front end of-the evaporator will cool the compartment. As the front end of the evaporator is normally cooler than the rear end, the auxiliary compartment will actually beat a lower temperature than the main compartment.

' convenience.

Alscanother very important advantage of this arrangement is .that the trays of ice cubes from the evaporator can be removed by merely opening-the auxiliary door 3 and without opening the main door, thereby conserving the low temperature in the main compartment. It will thus been seen that I have provided an improved and eii'icient door construction for refrigerators which is of great usefulness and Without taking up any extra spaceand with no substantial increase in cost an extra compartment is added. Any slight increase in cost will be more than oiiset by the increase in efliciency when it is considered that the auxiliary door can ,beopened up and still keep the compartment tightly shut.- This extra or'auxiliary compartment can be kept at a lower temperature than the rest of the refrigerator. Also it is praticularly handy to keep foods which are needed mostoften. a
