R. H. MONEY March 14, 1950 ROOM COOLER Filed Jan. 22, 1949 INVENTOR. fia/a/ra Herber/fi/mqy BY ATTQRNEYS Patented Mar. 14, 1950 UNITED ST TES PATENT OFFICE 2,500,852 ROOM COOLER Roland H. Money, Lima, Ohio, assignor to Artkraft Manufacturing Corporation, Lima, Ohio, a corporation of Ohio Application January 22, 1949, Serial No. 72,112
9 Claims. (Cl. 62-140) This invention relates toa room cooler and dehumidifier.
This invention contemplates a room cooler which is of simple structure, cheap to produce, eflicient in operation, and easily mounted upon, or removed from, the sill of a conventional window, such as a sliding sash type window, but my cooling unit can be used with hinged casement windows.
It is an object of the invention to produce a room cooler which is quiet in operation and this object is accomplished by mounting the motor compressor and condenser on the outside of the window. This arrangement also provides a simple and economical arrangement for dissipating the heat units into the outside atmosphere which have been extracted from the room being cooled.
The invention also contemplates a room cooler which is light in weight but of sturdy construction and which can be very easily and simply mounted in the window.
Fig. 1 is a vertical section through a window showing my room cooler in operative position.
Figs. 2 and 3 are sections along the lines 2--2 and 3-3 of Fig. 1.
Fig. 4 is a detail showing the mounting of the tubular frame on the window sill.
Referring more particularly to the drawings, there is shown a fragment of the room I which is to be cooled, having a floor 2, an outside wall 9, a sliding window sash 4, and a window sill 5.
My room cooler and dehumidifying unit comprises an inner housing 6 and an outer housing 7, each made of a light sheet metal such as aluminum. Housings and l are integrally joined together by two spaced L-shaped tubular supports 8 and 9. Preferably tubular supports 8 and 9 are of square cross-section.
The outside housing comprises a perforated bottom wall 10, imperforate end walls I I, an imperforate top wall l2, and an imperforate front wall l3. Rear wall M can be imperforate but preferably is in the form of grill to facilitate circulation of the air over the condenser l5 and the motor compressor unit-l6 which are mounted within housing I. A conventional fan l8, driven by electric motor I 9, is also mounted within housing 1 for circulating the air across condenser I5 and motor compressor unit l6.
Housing 6 is provided with an imperforate bottom wall 20 which is inclined downwardly toward the window sill 5. An evaporator 2i is positioned in the open front portion of housing 6 and a motor driven fan 22 is positioned within housing 6 in back of evaporator 2| for circulating the air from the room through evaporator 2|. The end walls 23 and the rear wall 24 of housing 6 preferably, but not necessarily, are imperforate but the top wall 25 is preferably in the form of a grill to facilitate circulation of the room air by the fan across or through evaporator 2| and out of the open front of housing 6.
Tubular support members 8 communicate with the lower corners of housing 6 as at 26 and with the upper inner corners of housing I as at 21. The evaporator 2| communicates with the low or intake side of compressor unit l6 by means of tube 28 and the high or exhaust side of compressor l6 communicates with condenser l5 and condenser 15 communicates by means of tube or liquid line 29 with the inlet side of evaporator 2i. It should be noted that the high compression refrigerant line 29 passes from the condenser I5 upwardly through tubular, frame member 9 to the evaporator and that the low side or suction line 28 is housed within tubular frame member 8. Lines 28 and 29 can be housed in either one of tubular frame members 8 or 9, but preferably are housed separately, as shown.
The electric power line or cable 30 for conducting current to the motor compressor unit 86 and fan motor l9 also passes through one of the tubular frame members which, by way of example, is tubular frame member 8. In addition to serving as a housing for refrigerant lines 28 and 29, and power line 30, tubular frame members 8 and 9 serve as drainage tubes or conduits down which the moisture condensed from the air being cooled flows from inclined bottom pan 29 to back wall it of outer housing 7 on and through the perforate floor Ill of the outer housing I.
A pair of rubber bumpers or supports 35 are mounted on the rear wall I of housing 1 adjacent the lower end thereof. These rubber supports or bumpers contact the outer face 36 of wall 3 to space housing 1 therefrom.
My room cooler unit is sufiiciently light so that it can be easily manually lifted into and out of the window opening. To assemble my unit in the window opening, sash 4 is raised and the cooler unit is set in the window opening with the horizontal portions of tubular frame members 8 and 9 resting upon the upper face of sill 5 and with the housing 1 positioned outside the the room, preferably out of doors, and the housing 6 positioned within the room. A pair of angle brackets 31 are secured by screws to the inner face of sill 5 and are provided with elongated openings 38.
A depending threaded stud 39 is welded on the outside of the bottom wall of each of the tubular frame members 8 and 9. These studs project through slots 38 and wing nuts 40 are threaded on the studs and when turned down clamp the frame members 8 to the angle irons 31 to hold the cooling unit in pace. The elongated slots 38 permit the unit to be adjusted in and out on the window sill so that the rubber bumpers 35 will abut the outer face of wall 3 before wing nuts 40 are tightened down. After the cooler unit is in place, sash 4 is lowered with the bottom frame member 4| in contact with tubular frame members 8 and 9 and the transverse tubular frame member 42, which extends between frame members 8 and 9 and closes off the space between the bottom edge of window frame member I and the upper face of sill 5.
In the operation of my room cooler, the plug 43 will be plugged into any convenient socket outlet and the mechanical refrigeration unit will be set in operation. The refrigerant will be compressed in compressor unit l6, condensed in condenser l5, evaporated inevaporator 2i, and returned to the compressor l6 through suction line 28, all in a conventional manner. However, the heat which is removed from the refrigerant in condenser I5 is not returned back to the room I but is dissipated to the atmosphere. The unit,
of course, will be provided with all of the conmoisture will flow down inclined bottom wall 26 of housing 6 into tubes 8 and 9 and thence through the bottom wall [0 of housing I on to the ground without.
I claim:
