FIG. I

INVENTOR George I. Wiese ATTORNEY 3 FIIIL I I FIG.3.

IIIIIIII I April 5, 1966 G. I. WIESE REFRIGERATOR CABINET Filed Dec. 29, 1964 United States Patent 3,243,972 REFRi-GERATOR CABINET George 1. Wiese, Avon, G'nio, assignor to Westinghouse Electric Corporation, East Pittsburgh, Pa., 2 corporation of Pennsylvania Filed Bee. 29, 1964, Ser. No. 421,870 16 Claims. {61. 62-414) This invention relates to refrigerator cabinet structures and more particularly to a domestic refrigerator cabinet having a plurality of compartments which are maintained at different temperatures.

With the increased need for greater freezer storage space, domestic refrigerators having a separate large frozen food storage compartment have increased in popularity. These refrigerated cabinet structures generally are provided with a closure member for the top, or above, freezing or fresh food compartment, and a separate drawer, or door, for the bottom, or below, freezing or frozen food compartment.

The provision of ice storage, or ice making apparatus in such two compartment refrigerators has heretofore presented numerous problems in that such apparatus or storage space is of necessity provided in the freezer compartment. With the numerous uses for ice cubes, especially during the warm weather, there is a constant opening of the large freezer door or drawer, with entry of warm air to the below freezing compartment and a resultant frost accumulation. In addition, many freezer compartments are located adjacent the bottom of the refrigerator cabinet, requiring the user to stoop when unloading the ice storage facility.

It is therefore an object of the present invention to prevent entry of large amounts of warm air to the freezer compartment when it is desired to obtain ice therefrom.

Another object of the invention is to facilitate removal of ice cubes from a refrigerated cabinet of the domestic type.

A further object of the invention is to provide an ice storage compartment for a domestic refrigerator which is easily accessible to the user, and is readily adaptable to refrigerator freezer cabinets as presently manufactured.

For a better understanding of the invention, reference should be had to the accompanying drawings wherein:

FIGURE 1 is a front elevational view of a refrigerator cabinet showing the invention employed therein and having portions of the structure broken away for clarity;

FIG. 2 is a vertical sectional view taken along line II-ll of FIG. 1 showing additional details of the cabinet of FiG. 1; and

FIG. 3 is a transverse sectional view taken along line Ill-J11 of FIG. 1 showing a portion of the invention in greater detail.

Referring to the drawings, especially FIGS. 1 and 2, there is shown a refrigerated cabinet of the domestic refrigerator freezer type. The cabinet comprises wall structure defining an upper compartment 11 maintained at above freezing temperatures, and a lower compartment 12 maintained at below freezing temperatures. The upper compartment 11 and lower compartment 12 are separated by a divider wall 13 comprising a horizontal portion 14 and an L-shaped portion 15, both of which extend from the rear wall of the cabinet 11 to the front of the cabinet. A mullion 17 is horizontally disposed across the front of the cabinet 10, and the horizontal portion 14 of the divider wall 13 has its front edge connected thereto.

The front opening of the compartment 11 has a closure member in the form of a hingedly supported door 18 of rectangular shape, having its lower edge 19 disposed adjacent the mullion strip 17 when in the closed position.

3,243,972 Patented. Apr. 5, 1956 The lower compartment 12 is provided with a closure member 21 having its upper edge 22 disposed adjacent the mullion strip 17, and serving to close that portion of the compartment front opening lying below the mullion strip from the outside ambient.

Referring again to FIG. 1, it should be noted that the Lshaped portion 15 of the divider wall 13 defines a small portion 23 of the compartment 12 disposed above the mullion strip 17, which is accessible when the door 13 is in the open position. An inner door 24 is disposed adjacent the forward edge of the L-shaped portion 15 to provide a seal between the air flowing in the lower compartment 12, which is below freezing, and the air flowing through the upper compartment 11 which is at a higher temperature.

To employ the portion 23 of the freezer compartment for ice cube storage or ice making apparatus, there is provided a shelf, in the form of a wire rack 26 horizontally disposed between the compartment portion 23 and the main compartment 12. The use of a wire rack 26 as a shelf member provides openings between the compartment portion 23 and the compartment 12 for the circulation of air therebetween.

As is best shown in FIGS. 1 and 2, the cabinet 10 is provided with a refrigerating system for maintaining the desired temperatures of the compartments 11 and 12, which system includes a heat exchanger in the form of a refrigerant evaporator 27. The refrigeration system is of the compressor-condenser-evaporator type well known in the art, and for the purposes of the present description only the heat exchanger 27 has been shown.

Both compartment 11 and compartment 12 are cooled by the fiow of air circulating from the evaporator 27 into the compartments and back to the evaporator in a circuitous path. To transfer air from adjacent the evap orator 27 there is provided an electric fan 28 disposed adjacent an opening 29 in the duct structure 31. The duct structure 31 has a pair of

openings

32 and 33 connecting with the portion 23 of the lower compartment and the upper compartment 11 respectively. A pair of

return ducts

34 and 36 are provided, one adjacent either side of the compartment 11, for return of air from the compartment to the evaporator 27.

When the fan 23 is in operation, air flow follows the general path indicated by the arrows shown in HQ 2.

Air enters the duct 31 and travels upwardly, some entering the portion 23 of the lower compartment 12 through the opening 32, then travelling downwardly through the wire rack 25 into the main portion of compartment 12. A cover plate 37 is disposed adjacent the evaporator 27 and extends between the side walls of the compartment 12. The cover plate 37 prevents air from flowing directly back through the opening 29, and forces the air to iiow downwardly through the compartment 12 and below the lower edge of the cover plate 37 to the evaporator 27. The remainder of the air travelling upwardly through the duct 31 is exhausted into the compartment 11 through the opening 33. Air, after passing downwardly through compartment 11, enters the

ducts

34 and 36 through the

openings

38 and 39 respectively, and travels downwardly, entering the compartment 12 through the

openings

41 and 42 adjacent the evaporator 27.

From the foregoing it should be evident that the various objects of the invention are achieved by the novel cabinet structure disclosed. The portion 23 of the lower compartment provides an ice storage or ice making enclosure which is readily accessible to the user while the freezer compartment door 21 remains in the closed position.

\Vhile the invention has been shown in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various additional modifications without departing from the spirit thereof.
