Application March 14, 1939, Serial No. 261,730

4 Claims.

This application relates to kitchen devices and more specifically to mechanical refrigerator units.

This application is a continuation in part of 5 an application of Guyon L. C. Earle, Serial No.

189,036, filed Feb. 7, 1938.

It is an object of this invention to provide a novel mechanical refrigerator unit.

The usual mechanical refrigerator has a box 10 shaped inner compartment for the refrigeration of food. Within this compartment is a cooling coil surrounding three, four or more ice cube trays. In refrigerators of comfortable capacity, the cooling coil does not usually take up all the 15 room available from the back of the coolingcompartment to the front and the space left either in front of or in back of the coil is wasted as far as use is concerned.

It is another object of this invention to elimigo nate the above mentioned disadvantage by providing a refrigerator in which the cooling coil and ice cube trays are located in an upper setback portion thereof.

It is another object of this invention to pro- 25 vide an upper shallow refrigerated compartment and a lower deep refrigerated compartment together with means for ensuring circulation of refrigerated air therebetween.

It is a further object of this invention to pro- 30 vide a table-top memberlocated on top of the bottom portion of said refrigerator which member is available as a working table and as a support for ice trays and food being taken out of and put in said refrigerator.

35 In modern homes and apartments, kitchen space is necessarily very limited. A refrigerator takes up much floor space in the kitchen and because of its shape, (it is usually much higher than the other units, that is, higher than the 4 stove, sink and table, and its depth is the same all the way up to its top, making it difiicult to reach cabinets placed above it) cabinets are not usually located above it. In such a situation, the best use of the space available cannot be made 45 as the cabinets do not fit snugly with the refrigerator. Moreover, there is usually no table space handy so that a portion of the articles to be placed in the cabinets are supported while the others are placed therein.

50 It is, therefore, another object of this invention to provide a refrigerator unit or ample capacity in which cabinet space is integral therewith and which is conveniently placed with respect to the table top member. 55 It is another object of this invention to use .is located outside of the unit), there is no need for open space between the top of therefrigeratorand the cabinets as in the usual arrangement, which open space is never efliciently used and which only serves to collect dirt.

Another feature of this invention is that the table top member conveniently and preferably serves as part of the drain board of a sink attached to one side of the refrigerator as in the parent application mentioned above. A stove is conveniently and preferably, located on the side of the sink remote from the refrigerator of this invention. Because of this invention, it is possible to place an ample sized refrigerator, sink and stove in a space not large enough for similar arrangements of the prior art.

Other objects and features of this invention, some of. them more or less ancillary or incidental to those above mentioned, will appear hereinafter as the description proceeds.

In the illustrated embodiment of this invention, which is herein described by way of example, there is provided a refrigerator unit comprising a vertical back wall, side walls and preferably two front walls, the top front wall being set back from and parallel to the bottom front wall. Atable top member is mounted on top of that part of the bottom portion of the refrigerator unit not covered by the top portion of the refrigerator unit. The top portion of the unit preferably contains the cooling coil, a plurality of ice cubetrays, a small refrigerated com- 5 partment preferaby for small articles, eggs, etc. at the side of the cooling coil, and cabinet space having a plurality of shelves therein. The cab-' inet space is preferably insulated from the top of the refrigerator itself. In the bottom of the 0 refrigerator unit, there is a large and deep refrigerated storage space having a plurality of selves therein. Between the upper and lower portions of the refrigerator itself and preferably placed at an angle with respect to a vertical plane so as to ensure circulation of refrigerated air to both front and back'of the lower portion of the refrigerator is a baflie member which preferably extends the entire'wldth of the cooling coil. Below this refrigerated space may be a compartment for the motor and compressor although this space is preferably also refrigerated and the motor and compressor located elsewhere, as, for example, beneath the sink if a sink unit is located adjacent the refrigerator unit. Lamps with a shade therefor may be provided over the refrigerator doors in the upper portion of the unit which may be lighted automatically upon opening the door beneath the respective lamp or they may be so arranged that their lighting can be controlled from without. The unit is preferably mounted on a recessed, base.

The invention will be more readily understood by referring to the following description and the accompanying drawing forming a part thereof, in which:

' Fig. 1 is a perspective view of an embodiment of the refrigerator unit of this invention with the various doors in the closed position;

Fig. 2 is a perspective view of the arrangement of Fig. l with the various doors in the opened position; and

Fig. 3 is a side elevation view in cross section of the arrangement of Fig. 1.

Referring more particularly to the drawing, Figs. 1 and 2 show, in perspective, an embodiment of the refrigerator unit I 0 of the preferred embodiment of this invention. The unit has a bottom portion l i and a top portion l2, the front 13 of which is parallel and set back from the plane containing the front M of the bottom portion. A back wall I5 is parallel to 'the fronts l3 and I4 and is either in one piece or in sections for convenience in manufacture and handling. Similarly the side walls l6 and I1 are each in one piece or in sections, the width of each wall being smaller for the upper portion than for the lower portion. The lower portion H has a bottom I 8 while a top I9 is provided for the upper portion l3- On top of all the bottom portion 'II which is not covered by the top portion i 2 and in front of this top portion is placed a table top member 20 of any suitable material such as metal or composition. The member 20 is: cold insulated from the bottom member l2. The unit is supported by any suitable means such as, for example, a recessed base 2| but it is to be understood that the unit may rest directly on the floor or have a plurality of supporting legs, if desired.

In the lower left hand part of the top member I2 is preferably placed a refrigerating coil 22 (see Fig. 3) the width of which is almost as great as the distance between the back wall l5 and the upper front wall I3. Thus there need be no waste space between the back of the coil 22 and the back wall 15 or between the front of the coil 22 and the front wall l3. Within the coil and in refrigerating contact therewith are four ice cube trays 23, 24, 25 and 26 the fronts of which are closely adjacent the inside surface of the door 21 which closes the ice cube tray compartment represented generally by the reference numeral 28. The door 21 has insulation therein and therearound so that it makes a good fit with the edges of the ice cube tray compartment 28 and thus prevents the escape of cold air to the room wherein the unit is placed. The ice cube trays 23 to 26, inclusive, are located in back of and slightly above the table top member. 28 which is a most convenient arrangement and one which will save the user many steps. Let it be assumed that the refrigerator unit of this invention is closely adjacent and the table top member 28 serves as the drainboard of a sink (as in the combination shown and described in the parent application referred to above) and that the user wishes to ice some bottled'drinks. The bottles of drinks would be uncapped on the table top member 20. Then an ice cube tray would be removed from the compartment 28 and rested on the table top member 28 at which place it is convenient to the sink where water can be obtained torelease the individual cubes or to-dilute the drinks. During all of these operations, the user does not have to take a single step. As soon as the ice cube tray is removed from the compartment 28 it can be rested on the table topmember 20, leaving the hands free to remove other articles (such as the bottled drinks, other ingredients for the prepared drinks, food, etc.) If many articles are removed from the refrigerator at one time many steps are saved. There is also a saving in power as the doors of this unit are not open long enough to allow much cold air to escape into the room as would be the case where the door would be open a long time during which repeated trips would \be taken between the refrigerator located elsewhere in the room and a table. The bottom edge of the door 21 is convenientlyv located so that it is sufliciently above the tabletop member 20 to clearthe top of an ice cube tray when the tray is resting on the table top member 28. Thus the trays 23 to 26, inclusive are close enough to the table top member 20 so that there 'is just one operation in sliding them out from their berths in proximity to the coil 22 and in placing them on the table top member 28 but high enough above the member 28 so that the door 21 may be immediately closed over the tops of the trays placed directly beneath the door 21 on the table top member 20. While four'ice cube trays have been shown. it is to be understood that more or less than this number can be used.

Beside the ice cube tray compartment 28 and separated therefrom in the front only by a common partition member 29 serving as a door jamb is a refrigerated compartment 38 which may have one or more shelves 3|. These shelves are of mesh so that the free circulation of cold air from the coil 22 to the lower portion of the refrigerator unit and back to the coil is not impeded. The compartment 30, which is closed by a door 32 which is. similar to the door 21, is ideally adapted for the storage of milk, soft drinks, beer, etc. In cases where tall bottles are stored, the upper one of the shelves 3| would be removed.

Above the compartments 28 and 30 is a cabinet 33 having one or more shelves 34 therein. The cabinet 33 is preferably integral with the refrigerator so that it forms a single unit therewith, thus preventing any waste space between the refrigerator and the cabinet, although it may, of course, be separate and mounted from the wall in such a way that it is-just above the refrigerator. The cabinet space is closed by doors 35 and 36 which when closed are preferably in the same plane as the doors 21 and 32. Between the upper portion of the refrigerator and the cabinet space 33 is preferably arranged a heavy insulating layer 31 so that the cabinet space 33 is maintained at room temperature. In a modification of this invention, however, the cabinet space 33 may be cold insulated around the sides. back and top, the layer 31 removed and the shelves 34 made of mesh material. In this modification, the cabinet space 33 is refrigerated. If desired, only the space occupied by the lower one or two shelves is refrigerated and the remaining shelves or shelf left at room temperature. As a further modification, the ice cube compartment 28 and the small refrigerated compartment 38 may be separated from the lower portion of the refrigerator by a space corresponding to the distance between any two shelves 34 or a multiple thereof. In this last arrangement a refrigersor-expander cycle.

ated compartment extending across the whole width of the unit would be located directly above the table top member 20. D

In another modification of this invention, the space between the first two shelves 34 may be occupied by one or more drawers for the storage of silverware, etc. cabinet space would be on top of these drawers and the height of the doors 35 and 36 would be correspondingly reduced (assuming that the overall height remains the same).

The lower portion ll of the refrigerator unit i0 contains a large percentage of the total refrigerated space. As the depth of the lower portion H is equal to the depth of the upper portion l2 plus nearly the entire depth of the table top member 20, and as there are no coil or ice cube trays to subtract therefrom, the cubic foot capacity of this lower portion is, in the usual case, large. An insulated door 41 closes this lower portion ll. Three mesh shelves 38, 39 and 40 and a solid bottom 4| are shown in the drawing but it is to be understood that this number of shelves may be smaller or larger, as desired. The lower portion H is cold insulated from the surrounding atmosphere but there is a circulation of air between the top portion i2 of the refrigerator and the lower portion II. This circulation is assisted by a baflle member 42 which is angularly mounted below the cooling coil 22 so as to divide the cold air between the back and the front of the lower portion II. This baflie 42 preferably extends the whole width of the cooling coil 22 and it deflects cold air to the front portion of the refrigerator where it might not otherwise circulate. Any other convenient means for promoting this circulation, such as a flue or a fan may also be used instead of or in addition to the baflie 42. A defrosting tray may be placed under the baflle 42. If desired the baffle 42 may be detachably mounted and thus removable when the refrigerator is defrosted.

Pipes 43 and 44 connect the cooling coil 22 to the compressor unit (not shown) which is located elsewhere, such as under the floor of the kitchen or in an enclosed space under the sink when the refrigerator unit is positioned adjacent a sink as in the arrangement shown and described in the parent application referred to above. The pipes 43 and 44 are shown coming out of the side l6 of the unit but they may come out at any convenient place.

Mechanically, the operation of the refrigerator unit is the same as in any well known mechanical refrigerator employing the compres- While an electric refrigerator has been shown, it is to be understood'that a gas refrigerator may be used -as well without departing from the spirit of this invention.

Between the compartments 2B-and 30 and the cabinet space 33 may be positioned electric lights 48 and 49 covered by a shade 50. These lights may be connected in a known manner to light up when the doors underneath them open or they may have pull cords attached thereto so that they may be operated by hand. A small light (not shown) is preferably located inside the upper portion i2 of the unit and connected to light up when the upper door is opened. There may also be a light in the lower compartment 46 which is lighted when the door 41 is opened.

If desired the lower portion of the refrigerator may be replaced by a refrigerated drawer section as shown in the parent application.

As another modification, the cooling coil and In this modification the ice cube trays may be located in the lower portion of the refrigerator and the portion of the refrigerator above the table top member used for refrigerator arranged in this manner.

It will be apparent that there has been described above a novel refrigerator unit which embodies a novel combination of an arrangement of a refrigerator and a table top member which saves space, time and money. Moreover, the positioning of the cabinet member integral. with the refrigerator conserves space and makes. for convenience in the kitchen and in fact quite revolutionizes the arrangement of smallkitchens.

With this refrigerator unit and the adjoining units architecturally well planned the combination of refrigerator, sink and stove (as shown in the parent application) may be so built in the end of the kitchen as to be in effect one of the walls of the room and the balance of the kitchen used as a beautiful dining space with no tall bulky ice box to destroy the streamlined harmony of the entire combination.
