12 Claims.

The present invention relates to refrigerators, and particularly to household refrigerators of the type embodying multiple cooling compartments.

More specifically, the invention pertains to improvements in the cabinet construction and compartment arrangement of a refrigerator of the kind mentioned, which improvements are .designed to increase the usefulness and practicability of the refrigerator.

It is the primary object of the invention to provide a. refrigerator devised to harmonize with modern kitchen cabinet units and to take up a minimum amount of 'space, while affording ample area for the storage of food and, in general, satisfying the requirements of a refrigerator of the stated type.

It is also an important object of the invention to provide a refrigerator cabinet capable either of being suspended on a wall or supported on a separate base, thereby providing a structure which lends itself most advantageously to general planning of modern kitchens.

Another and more specific object of the invention is to provide a hanging refrigerator structure embodying a relatively high temperature compartment for the storage of ordinary food, a relatively low temperature compartment for the storage 'of frozen food, and a fast freezing compartment for making ice cubes or the like, said compartments being respectively disposed to obtain the maximum efficiency for the particular purpose for which they are intended, said compartments further being arranged to afford sufficient storage space for their individual requirements without necessitating undue enlargement in the overall dimensions of the cabinet.

The invention is specially characterized by the provision of a refrigerator cabinet having a generally L-shaped cross-sectional configuration, the upright or vertical portion of said cabinet constituting a-food storage area as well as providing a housing for the refrigerator unit, and-the horizontal portion of the cabinet forming a worktable surface and affording a compartment for housing a low temperature evaporator element thus providing a convenient accessible area for the reception and storage of ice trays or the like.

Other objects and advantages of the invention will become apparent to those skilled in the art from the following detailed description based upon the accompanying drawings in which:

Fig. 1 is a perspective view on a greatly reduced scale illustrating the external structure of a refrigerator constructed in accordance with this invention;

Fig. 2 is a view similar to Fig. 1 but drawn on a larger scale with certain parts removed and other parts open to show the internal structure of the refrigerator;

Fig. 3 is a vertical cross-section taken substantially on line 3-3 of Fig, 2; and

Fig. 4 is a vertical cross-section taken substantially on line 4-4 of Fig. 2.

Referring more particularly to the drawings, there is shown therein a refrigerator cabinet designated in its entirety by the reference character 5. In accordance with the present invention, the cabinet 5 has a generally L-shaped cross-sectional configuration, comprising an upright or vertical portion 6 and a horizontal forwardly extending portion 1, the upright vertical portion 6 located to one side of the cabinet below the main food storage compartment 8 and opening at the bottom of said compartment, forms the well-type storage compartment 9; a reentrant metallic wall portion l6 disposed at the other side of the cabinet and below the main food compartment 8 forms the motor-compressor housing l0; and, a substantially rectangular metallic lining l'l mounted forwardly of said well-like member I5 and reentrant portion IG and supported within the horizontal portion 1 of the cabinet in spaced relation thereto, defines the ice freezing compartment l2.

. The spaces between the outer shell I3 and the inner liner M, the well-like member ii, the reentrant wall portion I6 and the rectangular lining II, as well as the spaces between said reentrant wall portion and said inner liner and rectangular lining, are filled with suitable insulating material l8, and the gaps between the outer shell I3 and the inner liner H at the open front of the main food storage compartment 8 and of the ice compartment I2 are sealed by means of breakerstrips i9 (Figs. 3 and 4).

The top-access opening of the well-type storage compartment 9 is closed by means of a cover 20 preferably consisting of a plurality of hinged sections, as best shown in Figs. 2'and 3; whereas the open front of the food storage compartment 8 is preferably closed by means of laterally swinging door or doors 2|, and the open, front of the ice tray compartment I2 may, as shown, be closed by means of a downwardly swinging door or doors 22. The doors 2! and 22 may be and preferably are of the conventional construction including interconnected outer metallic panels 23 and inner nonmetallic panels 24 having suitable insulating material 25 therebetween and provided with gasket strips 26 arranged to seal the access openings to said compartments 8 and If.

These compartments 8 and I2 and the well-type storage compartment 9 are cooled by operation of suitable refrigerating means. Preferably a primary refrigerating system is used to cool the ice tray compartment l2 and the well-type storage compartment 9, and a closed secondary system utilized to cool the main food storage compartment 8.

In the arrangement more clearly shown in Fig. 4, a motor-compressor 30 and a condenser 3|, in communication therewith through a pipe 32, are suitably mounted within the housing Iii. Leading from the condenser 3|, is a liquid line 33 which discharges into a series of cooling coils 34 arranged in heat exchange relationship with the lining ll defining the ice tray compartment l2. The series of cooling coils Sl communicate directly through an extension 35 with a second series of cooling coils 3G wound about and in heat exchange relation with the metallic well-like member l5 forming the well-type storage compartment 9. A return line 81 connects the second series of cooling coils 36 and a motor-compressor 30 thus completing the circuit of the primary refrigerating system.

In the arrangement more clearly shown in Fig. 4, the secondary system utilized to cool the main food storage compartment 8 comprises an evaporator portion consisting of a series of coils 38 in heat exchange relation with. the back and side walls of the metallic inner liner i4 defining said compartment 8. The series of cooling coils 38 communicates with a secondary condenser portion 39 located above said coils and conveniently arranged in heat exchange relation with the primary system, preferably with the return line 31 thereof which. for that purpose, may have a coil section I wound about said secondary condenser portion. The association and operation of the primary-secondary system of the above-described type are well-known in the art and form no part of the invention, and accordingly, a detailed description of the construction and operation thereof may be dispensed with herein.

However, it is pointed out that according to the present invention means is provided to effect proper cooling of the motor-compressor 30 and condenser 3i and for that purpose louvres I are formed in the bottom of the housing i below said unit and a duct 42 extends upwardly from the top of said housing and along a corresponding portion of the back of the cabinet thus providing a. path for the free circulation of air within said housing l0.

Also, according to this invention, the cabinet is provided with suitable recesses, preferably bayonet slots as indicated at 43, disposed for engagement with hangers 44 on a wall 45 or the like so that the cabinet may be supported in han position.

In use, the cabinet, may be hung on the wall in the manner above stated, or may be supported on a separate base such as a table, kitchen basecabinet or the like. It is to be noted that in mounting the cabinet care should be taken to provide sufficient clearance for an ample supply of air to and adequate circulation within the motor-compressor housing Hi.

It will be understood that the refrigerator cabinet, when supported in position, should be so located that the work surface II will be at the asoaasa proper level so that said surface may be utilized to advantage when placing or removing the food in or'out of the cabinet. It will further be appreciated that the work surface ll becomes umful in providing additional area for the preparation of food, etc.

The particular construction of the cabinet provides a compartment arrangement which will satisfy ordinary needs for the storage of various types of foods to the best advantage. Thus, the main storage compartment 8 provides adequate space and is most suitable for the storage and preservation of ordinary food; the well-type storage compartment is most convenient for the storage and preservation of frozen foods; and the forwardly extending ice tray compartment ll beneath the work surface portion 1' is most suitably situated for convenient handling of the ice trays indicated at 46 in the drawings. Moreover, the location and arrangement of the ice tray compartment I2 is such that it does not interfere with the space afforded for the storage of ordinary or frozen foods in their respective compartments 8 and 9.

It is believed that the invention, the mode of construction and assembly of its physical embodiment, and its advantages will be readily understood from the foregoing without further description; and it is to be understood that while a preferred embodiment of the invention has been shown and described for illustrative purposes, the structural details are capable of wide variations within the scope of the appended claims.
