Refrigerant condensed or generally represented by the reference character liquefied in the condenser 36 flows into a receiver In. The cabinet l0 comprises an outer metal tank 3! where it is stored prior to being conducted shell or panel ll enclosing walls of insulating through the pipe 22 back to the evaporating coil material l2 which surround an open-top metal L The cond t or p p 22 is pre erably of Small tank member l3 forming a compartment ll diameter and has a plurality of loops 39 formed 55 therein (see Fig. 4) to thus permit same to serve as a restrictor or expansion element for dividing the refrigerating system into high and low pres sure portions and for restricting the flow of liquid refrigerant to the evaporator 2|.
The stationarily mounted top wall portion of compartment 4 and cabinet I0 is provided with a depressed portion 4| which forms a bowl for receiving water discharged from a bubbler 42 mounted in the bowl. The discharge of water through bubbler 42 is controlled by a faucet or valve 43 also mounted upon the stationary top wall-portion l8 of the cabinet ill. The faucet or valve 43 is interposed in a conduit 44 which extends from a closed water conducting and cooling portion 45 of the water dispensing device of the apparatus. This water cooling portion of the device may be of any suitable or conventional form and is preferably constructed of superimposed and secured together sheet metal members having a closed sinuous passage 46 formed between the sheet metal members. tion 45 is therefore in the form of a flat platelike structure. A conduit 41 connected to one end of the passage 46 of the water cooler 45 extends through the bottom insulated wall l2 of compartment I4 and is adapted to be connected with a source of drinking water supply exteriorly of the cabinet. The sheet metal water cooler portion 45 of the water dispensing device may be supported within compartment 14 adjacent an upright wall thereof by being secured to suitable brackets 48 suspended from the underside of the detachable stationary top wall portion l8 of the structure. A conduit 49 extends from the bowl 4| down through compartment i4 and serves to convey water flowing into bowl 4| from the outlet bubbler 42 away from the cabinet It).
A body of liquid 5| is disposed within compartment l4 formed by the tank member l3. This body of liquid covers and surrounds the sheet metal water cooler portion 45 and serves to transfer heat therefrom to the refrigerant evaporating coil 2| of the refrigerating system to thus cool water or other beverage circulated through the cooler 45. Cooling of the liquid 5| by the evaporator 2| provides a body of cold liquid into which bottled beverages and the like such as bottles 52 may be placed for storage. The submerging of bottles 52 into the body of cold liquid 5| insures rapid cooling of their contents by the conduction of heat therefrom to the refrigerating coil 2|.
In Fig. 5 of the drawings I have disclosed a modified arrangement of the elements forming the top of cabinet II). It will be noted that in this showing of the structure the movable closure members or doors I'I are positioned or arranged to open from a diiferent side of the cabinet [0.
From' the foregoing it will be apparent that I have provided an improved refrigerating appa- The water cooler porratus of the combined water cooling and dispensing and bottled beverage cooling and storing type. My improved apparatus is constructed to be efiicient in operation and provides a practical apparatus for use in stores, gasoline filling stations, etc., where it is desired to serve custom-- a ers with cool drinking water and where such customers quite frequently desire to purchase bottled beverages. The water cooling and dispensing device incorporated in the improved apparatus is of such construction or form that it in no way interferes with the accessibility and removal or replacement of bottled beverages cooled and stored in the apparatus. The combined or unitary water cooling and dispensing and bottled beverage cooling and storing apparatus is small or compact and can be manufactured at low cost.
While the form of embodiment of the invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claim which follows.
What is claimed is as follows:
A unitary refrigerating apparatus comprising in combination, a cabinet having a plurality of walls forming an insulated compartment for the reception of articles to be stored and cooled and a machine compartment below the insulated compartment, a closed refrigerating system associated with said apparatus including an evaporator disposed in heat exchange relation with the interior of said insulated compartment and a refrigerant liquefying and circulating unit mounted in the machine compartment of said cabinet, the top wall of said insulated compartment including a detachable portion stationarily secured to said cabinet and a movable portion, said movable portion of said compartment top wall forming a door providing access to the interior of the insulated compartment, a beverage dispensing device associated with said apparatus, said device including a relatively flat closed fluid conducting portion disposed within said insulated compartment along a side wall thereof and attached to the stationarily mounted detachable portion of the compartment top wall, a conduit connecting said portion of said device with a source of fluid supply exteriorly of said insulated compartment, 2. faucet mounted exteriorly of the insulated compartment on the stationarily mounted detachable portion of the top wall thereof and having a conduit connection with said portion of said device within the compartment, and said insulated compartment having a body of liquid therein for transferring heat from said portion of said beverage dispensing device and from articles stored within the compartment to said evaporator of the refrigerating system.
