s claims. (crea-1oz) This invention relates to refrigeration and particularly to bottled beverage storage and refrigerating apparatuses.y c
- Since bottled beverage storage'and cooling apparatuses of the wet type, wherein the bottled beverages are stored in a liquid bath, have several disadvantages, namely, that `of dispensing a Wet bottle therefrom, from' which bottle liquid is Ylikely to flowor drip onto the consumer of the contents of the bottle and that of soaking labels oil the bottles before they are dispensed; attention has been focused on the provision of dry bottled beverage storing and cooling apparatuses. Dry bottled beverage ratuses have not, in general, been entirely satis-V factory because proper or ample cold air .circulation over the bottled goods has not been provided rapidly and uniformly enough in cabinets containing the bottled beverages. The present invention is, therefore, directed to the provision of a dry bottled beverage storage and cooling apparatus of improved characteristics and. novel" design. f i
An object of our invention is to improved bottled apparatus.
Another object of our invention is to provide an improved dry bottled beverage storageand cooling apparatus wherein the apparatus forms a dispensing devi provide ,an beverage storage and cooling ce and serving counter.
A further object of our invention is to provide a bottled beverage storage and dispensing apparatus wherein cold dry air is utilized for cooling the bottled goods to thereby prevent labels from being soaked off thebottles and. to permit the cooled bottled beverages to be `dispensed in a dry condition. y f
A still further and more specific object of our invention is to provide a dry bottled beverage storage and cooling apparatus having a horizontally elongated storage compartment provided with anovel and efficient duct arrangement for storage and cooling appaywall i3 hasa metal inner facing circulating relatively Warm air from the .com,
partment over a cooling element f of a refrigerating system and for distributing vthe cooled air in a plurality of streams uniformly throughout the length of the compartment, rection downwardly over and goods stored therein.
Further objects and advantages of vthe present invention will be apparent from the following description, reference being had to the accompanying drawings,- wherein a preferred' form of the present invention is clearly shown.
In the drawings:
Fig.' l is a perspective view of a refrigerating. apparatus constructed .in accordance invention;
Flg.-2is' a transversev vertical sectional view of the apparatus shown in Fig. l;l
Fig. 3 is a vertical sectional view tudinally of the apparatus shown in Fig. 1; and Fig. 4' is an enlarged vertical fragmentary sectional view vofthe appar the line 4-14 of Fig. 2 disclosing ,an air ductv leading from the vstorage compartmentof to the cooling element chamber thereof. Referring to the drawings, for illustr invention, wehaveshown in Fig. l thereof a dry bottled` beverage storage and refrigerating apparatus .comprising an elongated, generally reetangularlyhaped cabinet l0. Cabinet l0` includes a bottom kIhside i2 and end insulated walls I3. and il (see Figs. 2` and 3) all faced with a suitablev outer finished metalpanel or top of the cabinetincludes a stationary rear partyorservlng ledge iiiiand a. pluralityof ing or` openings which provide access terior of the cabinet. At one end horizontally disposed extension i8 a vertical extension` i9 of the cabinet bottom wall, il (see Figs. 3 and 4) to. form in the lower portion'of one end of thecabinet a machine compartment 2i forthe reception of a motor-compressor unit of a yrefrigerating system. Thus, theinsulatedwalls il, |2, i3, il, it and I9 together with the cabinetftop part or ledge i1 form a horizontally elongated storage compartment 22 within cabinet Il joining insulation thereofand forming a compartment 22. The metal' liner vention land welly t the refrigerator cabinet construction art. In the structure disclosed the doors close theaccess opening or openings in the top of cabinet i0 are slidably mounted on tracks orl supports 25 extending from the front to the rear of the cabinet. It is to be noted that the. cabinet top part or serving ledge i6is disposed above the tracks or supports 25 to provide a space therebetween to permit the doors l1 tc be slid from the front of the cabinetto the rear thereof for uncoveringy the access opening or openings.
