WATER COOLER BACKGROUND OF THE INVENTION 1. Field of the Invention This invention is directed towards water-cooling units and more'particularly is directed towards a new and improved potable water cooler of compact construction and adapted to maintain bottled drinking water in a pure, clean condition for extended periods.
2. Description of the Prior Art Water coolers that use bottled water normally. comprise an upright housing in which therefrigeration equipment is enclosed in the base and the top is formed with a plenum chamber adapted to receive and support an inverted bottle of water. The'plenum chamber is formed normally with a circularop'eningin its top wall to receive the neck of the bottle. Cooling coils are disposed in close proximity to the plenum chamber in order to refrigerate the water fedinto the chamber from the bottle. A spigot or valve is attached to the front of the housing and connects to the plenum chamber to permit cooled water to be drawn from the unit.
While water coolers of the foregoing type have been in common usefor many years they suffer'fromcertain problems, particularly with respectto cleanliness. The
plenum chamber for conventional water coolers re quires periodic cleaning to remove sediment, scum and algae that may form within the chamber; Thecleaning frequency is determinedlargely by the condition existing around the location of the unit; If the surrounding conditio'ns are clean then the cleaning requirement will be relatively infrequent, whereas in other locations, such as on trains or the like where dustand dirt are normally present; very frequent cleaningsmay be required in order to maintain a proper level of sanitation.
Accordingly, it is an object of the present invention to provide improvements in water coolers. Another object of the invention is to provide acompact, efficient water cooler wherein the water is cooled directly and the water is drawn off directly from the bottle.
' SUMMARY OF THE INVENTION This invention features a water cooler for use with bottled water, comprising a base, refrigeration equipment mounted within the base and an upper housing forming a chamber adapted to receive an inverted bottle of water. A valve cap is attached directly to the neckof the bottle and the cooling coils are mounted in the chamber for direct contact with the bottle. The refrigeration equipment is controlled by a pressure-sensitive switch mounted to a bottle support in the chamber and is adapted to turn off the refrigeration equipment when the bottle is empty. Stabilizing and cushioning means are provided within the housing to protect the bottle against vibration and support it in proper dispensing position.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 4 is a detailed side elevation of a valve cap employed in the invention. I
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawings, the referencecharacter 10 generally indicates a water-cooling unit generally organized about a cabinet housing 12 having a base portion 14, a mid-portion l6 and an upper portion 18. The base portion 14 is employed to house refrigeration equipment such as a motor and compressor generally indicated by the reference character 20. The refrigeration equipment 20 is connected to refrigerating coils 22 located in the upper portion 18 by conduits 24 and 26. The base portion 14 is provided with a horizontal upper wall 28 supporting a drain cup 30 mounted therein directly below a faucet 32 formed on a valve cap unit 34 for a water bottle 36' disposed in the upper portion 18. The drain cup 30 is provided with a tube 38 which may connect to a drain system or to a collection tank at the base to gather dripping, spillages and the like. If desired, the wall 28 may be slightly concave so as to guide any liquid falling on the wall 28 into the cup 30.
The mid-portion 16 is enclosed-on four sides by vertical walls with the front wall thereof being formed with access opening 40 allowing the user to reach in to place the cup under the faucet 32 and draw off water.
Mounted across the upper part of the mid-portion 16 is a horizontal annular wall 42 formed with a circular opening 44 somewhat smaller than the diameter of the bottle 36 but large enough to allowthe neck thereof to protrude therethrough when the bottle is placed in the inverted position shown in the drawings. Preferably, the wall 42-and opening 44-define a concaveshoulder 46 contoured to mate with the'rounded shoulder of the bottle 36. Preferably, the bottle is cushioned at its lower portion by means of a resilient annulus 48 mounted about the. upper end of the wall 44. Additional cushioning means may be provided at the lower part of the opening to provide vertical cushioning support for the bottle.
Mounted in the wall 42 and positioned to contact the bottle 36 is one or more pressure actuated switches 50 operatively connected to the refrigeration unit 20. The switches 50 are of the normally open type and are closed by the weight of a filled or partly filled bottle 36. As long as the switch is kept closed, the refrigeration unit 20 will operate in the normal manner. However, as the bottle empties, its weight is reduced and when empty or nearly empty the bottle becomes sufficiently light to permit the switch 50 to open. When open, the refrigeration equipment 20 becomes inoperative thereby preventing useless operation of the unit whenever a bottle is empty or not in place.
The bottle is provided with the valve cap 34, best shown in FIG. 2, which is both as a closure as well as valve for the bottle. The cap is tightly secured as by threading the same onto the neck of the bottle or by any other suitable means. The cap may be molded of an inexpensive plastic material so as to be disposable with the bottle, if desired. In the illustrated embodiment the cap is provided with a spring-loaded release button 52 which controls an internal valve element and it will be understood that depression of the button 52 will release water through the spigot 32. In FIG. 4 there is shown a modification of the combination valve cap and in this embodiment a spring-loaded lever 54 is provided to actuate a rotary valve component within the valve body, in the FIG. 4 embodiment the valve is opened by depressing the lever 54. v
The upper portion 18 of the housing forms a chamber to accommodate the bottle 36 and the cooling coils 22 helically arranged about a vertical axis. The diameter of the coil substantially corresponds with the outside diameter of the bottle 36 so as to contact the bottle when it is placed in position. By directly contacting the bottle, the water is kept cool within the bottle permitting it to be drained off directly from the bottle without unnecessary exposure to air and without contacting a plenum chamber or other area that may be subject to contamination.
In order to facilitate placement and removal of the bottle, the upper portion 18 is provided with a pair of hinged covers 56 and 58 connected to opposite sides of the housing as by hinges 60 and 62. The hinged covers when closed together may be locked as by a latch 64 at the top of the unit and, when the latch is released, the covers may be folded down out of the way to provide full access to the bottle. In the illustrated embodiment, the cover sections 56 and 58 are provided each with an arcuate shoulder 66 in.the top walls thereof with an arcuate resilient rib 68 disposed on the inner face thereof to engage the upper end of the inverted bottle 36. Thus, when the covers are brought together and locked, the upper end of the bottle is securely held in place, protecting the bottle from shifting or vibration.
Preferably, the covers 56 and 58 are lined with a layer 70 of thermal insulation material to minimize heat transfer. Optionally, the covers may extend upwardly to enclose only the cooling coils, leaving the upper end of the bottle exposed.
Having thus described the invention what I claim and desire to obtain by Letters Patent of the United States 1. A water cooler, comprising a. a housing having upper, middle and lower portions,
b. refrigerating means mounted in said lower portion,
