This '551' A compartment or drawer construction which colder air passes around this rear wall 36' into 55 the rear channel 30 in the refrigerator, down across the channel 38 along the bottoni of the structure and up through the front opening 39 of the bottom drawer Hc formed by the front and a baille 40 of the compartment as shown. 'This baille 40 does not extend the full height oi.' the drawer so that the circulation continues around it into the drawer interior.

A baille member 4I is placed between the respective compartments which does not extend the whole length of the drawer as shown. An opening remains over the rear of the drawer so that the circulation circuitV continues on upwards. If a drawer is opened -such as is lib the circulation passes around it and continues through the channel 42 formed between the bafile 4| and drawer bottom 26, up through the front opening 39 of drawer Il, into the compartment, and out again as hereinbefore through the rear top, through another channel 42 and up to the cooling unit I5 to complete the circuit. A baille wall 43 formsthe channel 30 with the rear wall I8 of the refrigerator. The channels 30, 38 and 42 extend acrossy the whole width of the interior. The openingsv 39 in the compartments Il are as wide as the drawers, as Figure 2 illustrates.

This modification will have a uniform cooling effect between the respective compartments. The novel arrangement illustrated practically isolates a compartment when it is opened up.

As seen in Figure- 1, drawer IIb is open, and the rear wall 36, reaching up to the baffle member 4| substantially shuts oi any of the possible ycirculation or refrigeration elciency. A roller and track assembly 3l may also be used for the drawers having a closing detent as hereinabove..

It is understood that my invention is not limited to the specific structures and designs as shown in the drawing, and that many modications and variations in the shape and form as well as the arrangements differing from the illustrated embodiments are possible within the broader scope and spirit of my invention. For example, one refrigerator may have several sizes of drawers or compartments; a larger construction may be employed for commercial units, such as for hotel use; brine piping may be employed along the rear wall to communicate cold air dlrectly to the individual compartments instead of using a central cooling unit; the drawers may have holes in the bottom for air circulation therethrough; other air circuit relations to cause continuous internal circulation may be designedi/'N 1. A refrigerator comprising in combination a casing comprising insulating material, a plurality of slidable drawers normally arranged in `yspaced apart parallel relation in said casing, a

baille wall spaced from the rear wall of said casing and positioned to form an abutment to be engaged by the rear walls of said drawers, and parallel baille members extending inwardly from the front wall of the casing to define compart ments for receiving said drawers.

2. A refrigerator comprising in combination a casing comprising insulating material, a plurality of slidable drawers normally arranged in spaced apart parallel relation in said casing, a baille wall spaced from the rear'wall of said casing and positioned to form an abutment to be engaged by the rear walls of said drawers, and parallel baille members extending inwardly from the front wall ofthe casing to dene compartments for receiving said drawers, said drawers being constructed and arranged to cooperate with the baille wall and baille members to form a circuit of connected passages for directing a temperature controlling medium along the rear and bottom walls of the casing and then successively through each drawer and along the associated baille member into the next drawer in the series.
