'This invention relates to a household refrigerator, and more particularly to a refrigerator having a draweradapted'to be maintained at temperatures below the freezing point of water.

Most household refrigerators are presently supplied with a drawer beneath the freezing compartment to be used for the storage of meat or the like. Between the drawer and the freezer compartment is usually considerable space; in general taken up by some sort of tray for catching the condensate from the coils when the machine is defrosted. This drawer is usually somewhat colder than the remainder of the refrigerator but is not cold enough for the storage of frozen foods.

The primary reason for the failure to utilize the space in such a drawer for frozen food storage has been the inability 'to fit the drawer close enough to the freezing compartment to maintain the low temperature, without, at the same time, allowing all the condensate and melting ice to fall into the drawer with the food.

The present invention makes possible the use of a drawer closely adjacent the lower surface of the freezing compartmentand insulating the drawer and, by the same means, providing a catch basin for isolating the condensate from the article in the drawer.

A more complete understanding of the advantages of the invention, and the invention itself, may be had by referring to the accompanying figures which form a part of the specification.

In the drawings:

Fig. 1 is a partially perspective view of the refrigerator with the door opend;

Fig. 2 is a fragmentaryfront elevational View drawn to an enlarged scale of one side of the drawer with a portion broken away to show its mode of attachment to the cabinet;

Fig. 3 is a sectional view along line 3-3 of Fig. 2;

Fig. 4 is a fragmentary top plan view of the drawer alone; 1

Fig. 5 is an end elevational view of the inner tray alone; and

'Fig. 6 is a partial top plan view of the tray alone. I

Briefly, myinvention comprises a refrigerator having a freezing compartment in the upper part of the cabinet. Immediately below the freezing compartment,- a drawer is provided. Thus, the cold air currents from the freezer "pass directly into the drawer. The drawer is provided with a false bottomwhich serves'both'to insulate the bottom of the drawer and to raisethe food in' the e '2 drawer above the level of the condensate which may drain into the drawer.

More specifically, and in reference to the drawings, my invention comprises a refrigerator having a cabinet H to which a door i2 is hinged. A freezing compartment is is located near the top of 'thefood compartment Hi. The interior of the cabinet is of conventional type, in general. Shelves i5 are provided for most food packages and a vegetable drawer I6 is located near the bottom of the compartment Hi. The thermostat controls I! are located above the freezing compartment on'the upper breaker frame It.

As stated, the above recited elements are usual and customary. The novel element of my invention lies in the provision of a drawer 2&3 capable ofstoring frozen foods at the necessary low temperatures to prevent thawing. This is accomplished by -means best illustrated in Figsp2-5 inclusive.

The drawer 20 is formed with an outwardly olfset wall 2 near its'upper edge on both ends of the drawer. These offsets 2! are slidably disposed in grooved brackets 22 fixed to the side walls of the inner compartment M by screws It. In the illustrated embodiment each bracket has two grooves 23 to'allow adjustment of the level of the drawer 20. Since the brackets are continu ous along theside' wall, it is apparent that convection currents from the walls of the freezing compartment; and the tubes 2 of the evaporator will be deflected into the drawer 2!.5 by the upper surface 25 of the bracket 22 along the sides of the cabinet. A bracket 25 having a si1nilar sloping surface 27 is fixed to the rear wall of the cabinet to deflect cold air from that portion ofthe freezer [3 into the drawer 2%. At the front of the drawer 2!! the lower edge 25 of the doors of the freezing compartment 53 extend downward almostto the upper surface as of the drawer. This arrangement serves further to direct the coldest air into the drawer.

'In the type of refrigerator illustrated having exposed evaporator tubes 24, the moisture in the airin'the refrigerator condenses on the tubes 24 and on the walls of the freezing compartrnent I hand either'freezes there or drops down. In

the' prior refrigerators, this condensate was caught ina flat dish under the freezing compartment. In'this embodiment, however, such an expedient is impossible since it would insulate the freezer drawer 20 from the cold air surrounding thefreezing compartment iii.

A fame: bottom isprovided' in the drawer 26 in the form of a tray 32. The inner bottom of the drawer is formed with upstanding ribs 33 and the tray is formed with downward extending ribs 34 which are spaced to lie between the ribs 33. The two sets of ribs 33 and 34 are the same height and, therefore, they combine to support the tray 32 in spaced relationship to the bottom of the drawer 20. Further support for the edges 35 of the tray 32 may be provided by a slight shoulder 36 formed on the inner surface of the drawer on which the edges may rest. These edges may, however, be spaced from the shoul-- der 36, as at 31, in order to allow condensate to run down the walls of the drawer 20. it is also envisioned that a small drain may be provided in the tray to allow moisture to drain into the drawer. Thus a false bottom is provided in the drawer allowing the condensate to fiow down into the space between the bottom of the drawer and the tray. This space also insulates the interior of the drawer from the rest of the cabinet so that the conduction of heat from the cabinet to the drawer will not be so rapid as to raise the temperature in the drawer above the desired temperature.

Defrosting a refrigerator of this type having an open drawer directly below the evaporator coils also presents a problem, since the melting ice, frost and water will fall directly into the drawer. The present invention makes possible the ready removal of all food from the drawer to facilitate this operation. At each end of the tray 32 an upstanding boss 49 is provided, rising from the adjacent flange. A pair of finger holes ii are formed in each boss 56'. Thus, it is possible to remove the tray 32 from the drawer 20 by inserting the fingers outwardly through the holes 4| under the upper wall 43 and lifting the tray together with the food thereon from the drawer. Small upstanding ribs 44 may be provided on the tray 32 to support the food thereon and to stiffen the tray. Thus the drawer is left empty and is prepared to receive the water and ice from the coils above it. When defrosting is complete, the drawer may be withdrawn and emptied or may be provided with a plugged hole which may be opened to drain into a receptacle more convenient to handle in a manner well known in the art.

The front of the drawer is preferably formed with an extended portion 46 somewhat in the manner of a flange, at the sides. These portions further enclose the drawer 20 and prevent heat leakage in the form of convection currents from the main storage part of the cabinet into the drawer. A recessed hand-hold 41 may be formed in the underside of the drawer to provide for easy withdrawal. The tray 32 may easily be formed to avoid interference with this handheld, and since it does not extend above the tray, the hand-hold in no wise diminishes the storage capacity of the drawer.

Both the drawer and tray are preferably molded from a plastic material, in part because of the need for the numerous ribs and the like. It is recognized, however, that other materials such as glass may also be used.

Having thus described my invention, I am aware that numerous and extensive departures may be made therefrom. without departing. from the spirit or scope of my invention.
