' (Cl. 62 s9) 6 Claims.
This invention relates to refrigerators and more specifically to means for improving the efllciency thereof.
It is an object of this invention to provide an improved mechanical refrigerator.
It is anotherobject of this invention to provide a refrigerator in which novel means for improving the circulation of cold air therewithin are provided.
It is a further object of this invention to provide a novel frozen food container, of large capacity.
In the usual refrigerator, an evaporator member, containing a number of coils through which a suitable refrigerant is caused'to flow, is positioned in the upper portion of the insulated box or casing member. The cold air produced by the evaporator flows (like water, but more slowly) downwardly through the shelves or drawers of the refrigerator, cooling the articles placed thereon or therein but during this process gradually having its temperature raised to such a point that r the warmedair rises until it reaches the evaporator where it is cooled again. There is thus at all times that the refrigerator is operating as such a downwardly flowing current of cold air and a rising current of warm air. (The terms cold and "warm are used for comparative purposes only as even the warm" air in the refrigerator is cold compared to room temperature.) In the ideal" case, the cold air flows downwardly under the evaporator and, after touching the bottom of the box, crosses over to the other side, if the evaporator is located at one side thereof, or to both sides if the evaporator is placed in the center of the upper portion of tho refrigerator. The presence of articles on the shelves or in the drawers, however, causes this ideal circulation of the air in the refrigerator to be disturbed as the articles deflect the cold air to such an extent that the flow thereof to certain parts of the refrigerator is prevented. Moreover, the warm air in some cases mixes with the cold air, withdrawing cold therefrom, and thus prevents certain parts of the refrigerator from becoming as cold as they would were not this mixing" takin place. The present invention in one of its primary aspects is concerned with the mitigation or prevention of this mixing of the cold air with the warmer air and, in general, with the improvement of the circulation of cold air in refrigerators.
The above-mentioned and other objects are attained in accordance witlifthe present invention by providing means for guiding the cold air from the evaporator to a point below the evaporator before it can contact any of the rising warmer air. This is accomplished in an illustrative embodiment of the invention, given by way of ex-- ample, by providing a baffle member at the side of the evaporator but spaced therefrom. This baflle member is in general parallel to the vertical plane bisecting the evaporator and extends, by way of example, the entire height of the evaporator, or more. The top of this baffle member is curved so that the warmair outside the member is directed to the top of the evaporator and not down in the space between the baflle member and the evaporator within which space the flow of cold airis unimpeded by either article's placed in the refrigerator or by warm air. I The invention is described below, by way of example, in connection with a' refrigerator of the set-back?" type, that is, one in which the plane of the front of the upper portion of the refrigerator (containing the evaporator) is behind or set back from the p1ane,of the front of the lower portion of the refrigerator but it is to be understood that the principles ofthe invention are applicable to any type of refrigerator. When the bafile is provided in a refrigerator of the set-back type the baffle and the evaporator are placed in the upper part thereof and preferably extend down as far as the upper part of the lower portion of the refrigerator, thus providingalarge space for ice cube trays and for a frozen food compartment. 1
The invention will be more readily understood by referring to the following description taken in connection with the accompanying drawing forming a part threof, in which:
Fig. l is afront elevationiview with\porti0ns broken away of a combined refrigerator and cabinet involving the invention;
Fig. 2 is a horizontal view partially in crosssection, taken along the line 2-2 in Fig. 1; and
Fig. 3 is a partial side view partly in cross-section of the refrigerator of Fig. 1.
Referring more specifically to the drawing, F gs. 1, 2 and 3 show, by way of example to illustrate the invention, a combined refrigerator and cab net unit 10 employing means (to be hereinafter described) within the refrigerator to increase the efficiency of operation thereof in accordance with the invention. The unit It) comprises a refrigerator I I, preferably of the set-back type disclosed in Earle Patents 2,180,460, issued November 21, 1939, and 2,312,326, issued March 2, 1943, and a cabinet I2 located above the refrigerator.
cabinet l2, comprising a shelved enclosure l3 closed by one or more doors l4, serves no function The 2 in the improvement of the refrigerator operating efficiency sofurther description thereof is unnecessary.
The refrigerator ll preferably comprises a lower refrigerated portion 20 supported on a recessed base 2|, an upper refrigerated portion 22 located above the lower portion 20 but the food and other articles to be refrigerated. If desired, one or more of the lower drawers can be longer than the top one in order to provide better circulation of cold air to the lower drawers.
For a more complete description of set-back refrigerators employing drawers, reference is made to the above-identified Earle Patent 2,312,326.
The upper portion 22 is provided with an evaporator 28 comprising a shell or container for supporting evaporator coils (not shown) and having, by way of example, and as shown in Fig. 2, corrugated sides 29 and 30 and back 3| of any suitable form to provide maximum exposed area. Coils containing the cooling medium pass through or are supported by the back 3| and the sides 29 and 30 (or one or more of them) and are con nected to the compressor-condenser unit prefer ably located outside the refrigerator unitl Within the, shell of the evaporator 28 are two shelves 32 and 33 to support ice cube trays 40 and 4|, respectively, or other articles to be frozen. If desired, cooling coils may pas through these shelves. Below the shelves is a relatively large chamber 34 which is suitable for retaining frozen foods of relatively large size. This chamber extends down almost as far as the top of the up permost drawer 24 in the lower portion of the refrigerator and thus utilizes the spacebetween the sill of the door 48 and the top Of the drawer 24 which would otherwise not be used. Additional coils may run around the sides, back or front of the chamber 34 (or any one or ones of them) to make this chamber colder than the rest of the refrigerator. In the lower portion of this chamber-34 a mesh basket35 which may have either a solid or a mesh base is supported by lips 36 attached to and projecting inwardly from the sides 29 and 3!]. cube trays 2 and 43 can be supported from lips 31 and 38, respectively, similar to lips 36, after 'the mesh basket has been. placed into position within the chamber 34. The lips ,36, 31 and 38 may be parts of strong flanges of seats running around the inside of the chamber 34. They are made strong enough so that levers can be used to force the ice cube trays 42 and 43 and the mesh basket 34 from the adjacent lips if they should become frozen thereto. The shell 34 may have a bottom or not, as desired. Positioned at the side of the evaporator 28 in the upper portion are mesh shelves 44, 45 and 46 for the support of food. The two upper shelves preferably have a cut-out portion, as shown in Fig. 2, so that bottled drinks, milk or other articles having .a
height greater than the distance between shelves can be accommodatedwithout turning them over On their sides. Doors 4! and 48 are provided as closure members for the upper refrigerated. portion 22.
As is well'known, heat is taken from the in- Two additional ice..
. 20 is preferably provided with a, plurality of drawers 24, 25, 26 and 21 to hold terior of the refrigerator by the refrigerant circulating through the coils of the evaporator 28. Thus the temperature of the 'air immediately surrounding the coils is lowered. In order to provide mean for conducting this cold air directly to the lower portion of the refrigerator before it can be mixed with the warmest air in the refrigerator (that returning to the evaporator coils), the baffle member 50 is provided which extends, for example, horizontally from front to rear in the upper portion of the refrigerator and vertically from the region of the top of the evaporator to the region of the bottom thereof. Preferably the u per part of the baflle member is curved towards the evaporator so as to allow the warm air (indicated by the dotted arrows) to pass over the top of the baflle member without encountering the colder air (indicated by the full line arrows) between the baffle member and the evaporator. The cold air in the back of the lower portion of the refrigerator setsup a fairly rapid circulation of current of refrigerated air. The drawers project into this current and remove some of it, thus permitting a slower horizontal circulation of cold air in each drawer.
It will be apparent that by providing a baflle member 50 as described above, cold air can reach the lower portions of the refrigerator more directly than in the refrigerators of the prior art wherein milk and other bottles and other large articles prevented the direct flow Of cold air to the bottom of the refrigerator and the cold air became mixed with warmer air returning to the evaporator coils. .The circulation of cold by convection, conduction and radiation is otherwise similar to that in the arrangements of the aboveidentified Earle' patents. Moreover, by providing a frozen food compartment having flanges 36, 31 and 38 upon which ice cube traysor food baskets can rest (instead of shelves, the space between the level of the'lower sillof the door 48 and the top of the drawer 24 can be used for frozen food purposes or for additional ice cube containers. I p
Obviously, the invention is not limited to the specific form or position of the means for separating the cold air from the warmer air shown in the drawing, as will be apparentfrom the appended claims. 7 I
