DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings, which are described below. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. The invention includes any alterations and further modifications in the illustrated devices and described methods and further applications of the principles of the invention, which would normally occur to one skilled in the art to which the invention relates.

Now referring to FIG. 1, a water cooler is shown, generally indicated as 10. Water cooler 10 includes a cabinet or housing 12 and controls 14a, 14b, and 14c. Housing 12 has a top wall 15 having an opening 15a therein for receiving water from a water bottle 16. In the embodiment shown, controls 14a and 14c are push-button controls for dispensing the water, and 14b is a slide control for adjusting the temperature of the water dispensed through control 14c. Water cooler 10 is capable of storing and dispensing water from water bottle 16 at room temperature, at a chilled temperature, or at a heated temperature, as is known. Water bottle 16 includes a neck 17 having an opening, generally indicated as 18, at an end thereof (FIG. 3). Opening 18 is covered by a cap, generally indicated as 19. Cap 19 includes a central tubular section, generally indicated as 20, and a resealable inner cap 22 covering an end of the tube, as is known.

Referring now to FIGS. 2-5, water cooler 10 includes an assembly, generally indicated as 30. Assembly 30 includes a cylindrical reservoir, generally indicated as 32; a bottle retainer, generally indicated as 34; a separator body, generally indicated as 36; and a mounting ring, generally indicated as 38. Reservoir 32 includes a generally annular mounting flange 40, and a generally cylindrical side wall 42 having an upper portion 42a and a lower portion 42b, which has a slightly smaller diameter than upper portion 42a. Reservoir 32 also includes a shoulder or ledge 44, connecting upper portion 42a and lower portion 42b, and a bottom 46. Reservoir 32 also has an outlet opening/port 48, in upper side wall portion 42a for dispensing room temperature water, as is discussed in further detail below. Bottom 46 includes two outlet openings or ports 50 and 52. Outlet opening 50 is for dispensing chilled water, and outlet opening 52 includes a tube 54 extending down from bottom 46 leading to a chamber for heating water, as is discussed in further detail below. Two locking projections or tabs 56 extend inwardly on the interior of tube 54, as best shown in FIG. 11. The projections are configured to lock separator body 36 to the reservoir, as discussed below. Tube 54 also includes a sealing surface 58 on the interior of the tube above projections 56. Reservoir 32 is preferably made from a corrosion-resistant material, such as plastic, and may be formed as a unitary piece by a process, such as injection molding. The reservoir may also be made out of corrosion-resistant metal, such as stainless steel or aluminum.

Bottle retainer 34 includes an annular mounting flange 60 mounted around opening 15a in top wall 15 of the water cooling housing and a side wall 62, including a funnel-shaped inclined portion 62a extending down from mounting flange 60 and configured to receive bottle 16, and a vertically oriented cylindrical lower portion 62b. Bottle retainer 34 also includes a bottom 64 connected to lower side wall portion 62b and an opening 66 located in the center of bottom 64. Bottle retainer 34 also includes an annular locating flange 68 that extends in a generally vertical orientation. Locating flange 68 includes four equally spaced outwardly extending locking projections 70 (see FIGS. 12 and 12A) for locking the bottle retainer to mounting ring 38. Locating flange 68 also has four gussets 72 located on the opposite side of the ring from locking projections 70 to provide structural support. Bottle retainer 34 is preferably made from a corrosion-resistant material, such as a plastic that may be formed by the injection molding process or may be stamped from a corrosion-resistant metal, such as stainless steel or aluminum.

Now referring to FIGS. 6-10, separator body 36 includes a generally circular base 80, a probe, generally indicated as 82, extending generally perpendicular from base 80 along an axis A of the separator body (FIGS. 9 and 10), and a tube, generally indicated as 84, extending along axis A from the opposite side of base 80 from which probe 82 extends. Separator body 36 also has a pair of gripping members or flanges 86 that extend generally perpendicular from base 80 on either side of probe 82, to provide a location for applying a torsional rotating force to the separator body, as discussed below. Also, on the bottom of base 80, four equally spaced gussets 88 are provided that extend generally perpendicular from base 80 from the same side as tube 84 to provide structural support.

Probe 82 of the separator body includes four flanges 90 arranged in a cruciform configuration centered on axis A and that define channels 92 therebetween. Probe 82 also includes an upper end 94 for engaging inner cap 22 on water bottle 16 and a groove 96 located between upper end 94 and flanges 90 for receiving a lip on the inner cap, as is known.

Tube 84 of separator body 36 includes a cylindrical wall 100 defining an interior space 102. Tube 84 also includes a circumferentially extending channel 104 formed on the outside of wall 100 for receiving a compressible resilient sealing ring 105. Tube 84 also has a pair of outwardly extending locking tabs or projections 106 located below channel 104 and on opposite sides of the tube, as best shown in FIGS. 6 and 9. Also, as best shown in FIGS. 8-10, flanges 90 and channels 92 of probe 82 extend partially into tube 84. In addition, separator body 36 includes four openings 108 extending through base 80 that coincide with channels 92 to provide communication from the interior 102 of tube 84 to the top side of base 80. Separator body 36 is preferably made from a corrosion-resistant material, such as plastic, and may be formed by the injection molding process.

Mounting ring 38 (FIG. 13) has a generally annular configuration and a generally L-shaped cross-section including an upper leg 110 and a downwardly extending leg 112. Mounting ring 38 also includes four equally spaced L-shaped locking recesses 114 located on the inside of leg 112. Locking recesses 114 each have an upper leg 116 open at the top end of the mounting ring, and a lower leg 118 having a generally horizontal orientation. Mounting ring 38 is positioned between mounting flange 60 of bottle retainer 34 and mounting flange 40 of reservoir 32, and the locking recesses 114 are configured to receive locking projections 70 on locating flange 68 of the bottle retainer, as discussed below. It should also be appreciated that, although retainer ring 38 is shown as a separate member, it may also be molded integrally with top wall 15 of housing 12.

To install assembly 30 in water cooler 10, reservoir 32 is placed in the top of cabinet 12 with mounting flange 40 located at the upper end thereof. Mounting ring 38 is located above mounting flange 40 with upper leg 110 extending around opening 15a in the top wall of the housing, as best shown in FIGS. 3-5. Separator body 36 is installed in the reservoir by inserting the lower portion of tube 84 into tube 54 with probe 82 extending upward in the reservoir, as shown in FIGS. 3-5. To insert tube 84 into tube 54, projections 106 are inserted between and pushed beyond inwardly extending locking projections 56 on the interior of tube 54. When locking projections 106 are inserted in tube 84 past locking projections 56 on tube 54, the separator body is rotated and locked into position by using gripping flanges 86 to provide leverage for rotational movement. The separator body is turned until locking projections 106 are located below locking projections 56, which locks the separator body into place in the reservoir. In addition, when the separator body is locked into the reservoir, a fluid seal is formed between tube 84 and tube 54, as sealing ring 105 is compressed between channel 104 and sealing surface 58. Also, when the separator body is locked to the reservoir, base 80 will at least partially overlie shoulder 44, but a small gap is formed between the base and shoulder so that water can flow therebetween. When the separator body is installed, the base creates two chambers: a lower chamber 120 and an upper chamber 122, in the reservoir (FIG. 3). Lower chamber 120 is defined by lower side wall portion 42b of the reservoir, base 80 of separator body 36, and bottom 46 of the reservoir, and upper chamber 122 is defined by upper side wall portion 42a of the reservoir, base 80 of separator body 36, and bottle retainer 34. Also, when the separator body is assembled thusly, outlet opening 48 will be above base 80 of the separator body, providing an outlet to upper chamber 122.

Next, bottle retainer 34 is installed on assembly 30 by lowering the bottle retainer so that the upper end 94 of probe 82 goes through opening 66 in bottom 64 and continuing to lower the bottle retainer until the probe is approximately half way up lower side wall portion 62b of the bottle retainer, as shown in FIG. 3. To lock the bottle retainer in place, locking projections 70 on locating flange 68 are positioned for receipt in respective upper legs 116 of locking recesses 114. Locking projections 70 are then pushed down into the lower leg 118 of recesses 114, wherein the bottle retainer can be rotated to lock it into position with respect to the mounting ring. When assembled thusly, reservoir 32, bottle retainer 34, separator body 36, and mounting ring 38 are all centered and aligned along the common axis A of the separator body.

To operate water cooler 10, a water bottle 16 is inverted and installed in the sequence shown in FIGS. 3-5. First, any label or protective seal covering tube 20 in cap 19 is removed and the bottle positioned with neck 17 and cap 19 in lower side wall portion 62b of the bottle retainer (FIG. 3). As the bottle is lowered, probe 82 enters tube 20 of cap 19 and the upper end 94 of probe 82 engages inner cap 22, as shown in FIG. 4. Also, a lip along the bottom inner edge of inner cap 22 is received in groove 96 of probe 82, which holds the inner cap on the probe, as is known. When the bottle is completely in place and resting on and supported by bottle retainer 34, the upper end 94 of probe 82 has pushed inner cap 22 away from tube 20, as shown in FIG. 5, allowing water to flow from the bottle through channels 92 of the probe into reservoir 32.

In the reservoir, water will flow through openings 108 in base 80 into and down through tube 84 and into a fluid compartment (not shown) for heating water to be dispensed by control 14a on water cooler 10. When the hot water fluid compartment is filled, tube 84 fills to the top and additional water flowing from water bottle 16 flows around the edges of base 80 and between the base and shoulder 44 into lower chamber 120. As chamber 120 is filled, the water level rises into chamber 122. The water level continues to rise until it meets the bottom of neck 17 on water bottle 16, wherein further air exchange with the water in the bottle is precluded. Water in chamber 120 is chilled by a known refrigeration system and can be dispensed through outlet opening 50. Water in upper chamber 122 remains at approximately room temperature and can be dispensed through outlet opening 48. Also, water cooler 10 may be equipped with a mixing valve to mix the water exiting outlet opening 48 and outlet opening 50 or 52 so that the water is dispensed at a desired temperature.

When it is desired to remove water bottle 16, the lip on inner cap 22 in groove 96 of probe 82 will hold the inner cap on the probe until the inner cap is reinserted in and sealed in tube 20, as water bottle 16 is lifted away from assembly 10, as is known in the art. This prevents any water remaining in water bottle 16 from accidentally leaking out.

Referring now to FIG. 14, an alternate embodiment of the separator body is shown, generally indicated as 136. Separator body 136 is similar in all aspects to separator body 36 except that separator body 136 includes a slotted opening 183 in a tube 184 extending from base 80. With opening 183, when the hot water chamber is filled, water can flow through tube 184 directly into chamber 120 without having to go between the edge of base 80 and shoulder 44. In all other respects, separator body 136 is assembled and operated as separator body 36.

While the invention has been taught with specific reference to these embodiments, one skilled in the art will recognize that changes can be made in form and detail without departing from the spirit and scope of the invention. For example, the probe may have a tubular configuration with water and vent ports for water and air to flow therein as opposed to the cruciform configuration shown in the figures. In addition, more or fewer gripping flanges may be provided on the separator body, and the flanges may be formed in any suitable configuration that will assist in rotating the separator body. The gripping flanges may also be provided on the probe. Also, one or the other of tube 84 and tube 54 may contain recesses to receive mating projections, like the mounting ring, as opposed to providing locking projections on both tubes. Furthermore, the configuration of the recesses in the mounting ring may be varied, or the mounting ring may include locking projections to lock with projections 70. Alternately, the recesses may be included on the locating flange, and the projections may be included on the mounting ring. The described embodiments are to be considered, therefore, in all respects only as illustrative and not restrictive. As such, the scope of the invention is indicated by the following claims rather than by the description.
