The most pertinent prior art of which applicant is aware are US. Pats. Nos. 2,311,549'and 2,317,816. These patents, however, do not disclose the invention disclosed and claimed here.
BRIEF DESCRIPTION OFT-HE DRAWINGS FIG. 1 is an elevational view partly broken away of a refrigeration apparatus embodying the invention.
FIG. 2 is an enlarged fragmentary sectional view taken substantially along line 2-2 of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT hinged access door 14 and 15, respectively, with these doors being shown in open positions in FIG. 1.
As can be seen inthe enlarged'fragmentary horizontal section of FIG. 2 the separator wall 13 is provided with insulation 16 and has a top shell 17 and a bottom shell 18.
Located in the separator wall 13 is a butter conditioning and storage compartment means 19, hereinafteridentified as a butter compartment, and this compartment is in heat exchange relationship through and around a closure 25 with the refrigerator 11 to bechilled thereby.
In order to maintain the interior of the butter compartment 19 at the desired temperature it is provided with heating means illustrated by the resistance wires 20. These heater wires 20 are located at the external shell 2l of the separator wall and are of the type customarily used to prevent moisture'condensation on the outer surface of the shell. The means 22 for mounting the heater wires 20 On the shell 21 also mount the wires, in close proximity to the butter compartment 19 so that the compartment and the butter 23 which is here shown as a customary quarter pound stick can receive heat from these heater wires 20. If additional, heating is required or desired, the compartnent 19 itself can in- ,clude its own resistance heating wires as illustrated at The butter compartment 19 has its outer end adjacent the refrigerator access door 14 so that the opening of the door 14 immediately provides access to the butter compartment and its bottom closure door 25. The butter compartment door 25 is hinged at the rear about a hinge pin 26 and is movable from the closed position shown in FIG. 2 to the open position 27 shown in broken lines in FIG. 2 by moving the door about a relatively small angle.
The extent of opening movement of the door 25 is limited by a scoop-shaped stop 28 with an open front 29 with the result that when the door 25 is in its lowermost'position the butter 23-and the removable tray 30 on which it rests is readily accessible from the front of the refrigerator. When the butter compartment door 25 is in its raised closed position-where it is held by a steel spring retainer 31 the open front 29 of the stop 28 is concealed behind a masking flange 32 on the door 25.
As can be seen from the above description, the butter conditioning and storage compartment of this invention has a number-of very important advantages. Thus it provides for storage of butter at a desired't'emperature by using the heating means normally provided in a refrigeration apparatus of'this type. It also provides a butter compartment without reducing the-storage space of the refrigerator-by using space normally occupied by insulation. Also, if additional heat should be required to maintain the proper temperature in the butter compartment this is easily achieved as by the heating wires 24 and this auxiliary wiring is conveniently adjacent to the existing refrigerating wiring such as that shown at 20 with the result that no expensive wiring modifications or extensions are necessary. If desired, this construction provides a ready adaptability to added louvers for directing low temperature air into the compartment for storing the butter in a hard condition for maximum storage life if such should be desired.
Another advantage of this construction is that substantially all the parts except the metal spring retainer 31 can be made of molded plastic that may be snapped together. j
