WATER COOLER Filed Oct. 14. 1950 INVENTOR Frank D. PeH'ien ATTORNEY the lower Patented Jan. 24, 1933 UNITED STATES PATENT OFFICE FRANK D. PELTIEB, 0F EVANSVILLE, INDIANA, ASSIGNOR TO SERVEL INC., OF NEW YORK, N. Y., A CORPORATION OF DELAWARE WATER COOLER Application filed October 14, 1930. Serial No. 488,606.

This invention relates to a water cooler refrigerated by mechanical means and more particularly to a device of this character refrigerated by a hermetically sealed refrigerating unit which, together with the evaporator, condenser and connections, may be removed as a unit from the structure comprising the water cooler cabinet and tank.

The invention will be readily understood by reference to the following description taken in connection with the accompanying drawing in which the figure is a vertical section of a mechanically refrigerated water cooler constructed in accordance with this invention.

The water cooler shown in the drawing comprises a cabinet structure and a refrigerating unit detachably mounted in said cabinet. The cabinet comprises a framework 11 and metal walls 10. A flue is formed at the rear of the cabinet by a metal casing 13 welded or otherwise suitably attached to the rear wall of the cabinet. Openings 13a in the rear wall of the cabinet afford communication between ortion of the interior of the cabinet and the ue. A flanged opening 14 is provided in the bottom of the cabinet to allow air to flow upwardly into the lower part of the cabinet, through the openings 13a, and then up through the flue in the rear of the cabinet. A suitable top 15 is provided for the cabinet which top extends over the upper end of the flue and is provided with a suitable outlet opening 16 for air ascending the flue. A section 12 of the cabinet wall is made removable to allow the refrigerating unit to be readily inserted or removed as herein described.

'Mounted on the framework 11 are angle irons orbrackets 33 which support a vessel or tank 19 for containing the fluid to be cooled. This tank has a circular opening 26 in the bottom thereof to admit the evaporator of the refrigerating unit when the latter is positioned within the cabinet. A fluid supply line 20 connects with the tank to supply liquid, for instance city water, thereto, to be cooled. Cooled fluid is discharged from the tank through pipe 21 and faucet '22. A drain 49 is positioned on the front of the cabinet under the faucet as usual.

A plate 17 is welded or otherwise suitably secured in position a slight distance below the tank to divide the interior of the cabinet into an upper compartment in which the cooling tank is located and a lower compartment for housing a mechanical refrigerating unit. Partition plate 17 is provided with a central flanged aperture 17a through which the evaporator is inserted when the refrigerating unit is mounted in position within the cabinet as will be described.

The chamber above partition plate 17 is filled with heat insulating material 18 which completely surrounds the fluid tank 19 except for a passage immediately below said tank extending between the aperture in the partition plate 17 and the aperture in the bottom of the tank.

The refrigerating unit comprises a mounting block 36 from which is suspended a condenser 40 by rods 39, an hermetically sealed motor-compressor unit suspended intermediate the mounting block and the condenser by lugs 38a clamped between resilient blocks 39a held in position by flanged nuts 3% threaded on supporting rods 39; and an evaporator mounted on the upper side of mounting block 36, which evaporator comprises a casing 27 and a base plate 29 enclosing a chamber adapted to contain a liquid refrigerant.

A conduit 41 conducts liquid refrigerant from condenser 40 to the evaporator in which the liquid level is maintained substantially constant by a refrigerant inlet valve 42 operated through levers 43 and 44 by float 45. A Vapor suction line 46 extends from a point near the top of the evaporating chamber downwardly through the base 29 and the mounting block 36 to the intake of the compressor unit 38. The vapor suction line 46 also serves as a guide for the float 45 within the evaporator chamber.

When the refrigerating unit is to be assembled with the cabinet, plate 12 is removed and the unit is inserted through the opening in the rear of the cabinet thus exposed. The evaporator is inserted through the opening in partition plate 17 and the aperture in the bottom of the liquid tank 19. The unit is secured in position by any desired means such as bolts 35 which secure the mountin block 36 to the partition plate 17 and a stu bolt 31 integral with the evaporator casing 27 perform the dual role of holdin the unit in position and at the same time olding a cover 24 on the tank 19 by means of nuts 32. A asket 25 seals the joint between the tank an its cover and there are also provided gaskets 28 and 37 to seal the joint between the base of the evaporator and the bottom of the fluid tank, and the joint between the mounting block 36 and the partition plate 17 respectively.

When the refrigerating unit is thus mounted in position the evaporator is within the tank 19 for cooling the fluid therein and the condenser is positioned in the aperture in a baflle plate 47 within the bottom portion of the cabinet so that all the air entering the bottom of the cabinet through aperture 14 will pass over the condenser coils and then through openings 13a and up through the flue in the rear of the cabinet. Since the motor-compressor unit is mounted above the condensers the air for cooling the condensers will not have been previously warmed by contact with the motor-compressor umt.

It will be obvious to those skilled in the art that various other changes may be made in the construction and arrangement without departing from the spirit of the invention and therefore the invention is not limited to what is shown in the drawing and described in the specification but only as indicated in the appended claims.
