AIR COOLER AND REFRIGERATOR.

Application filed April 27,

This invention relates to a refrigerating device and pertains particularly to a devlce designed especially for cooling the air of a room or a building.

The primary object of the present inventions is to provide a new and novel as well as efficient means for effecting the lowering of temperature in homes, public buildlngs and other places where such 'lowerlng of the temperature is desirable.

The invention broadly contemplates the provision of a cabinet housing, a compressor, an air circulating fan and a refrlgerating fluid containing unit having means whereby air may be circulated in close proximlty to the fluid to be cooled thereby.

Numerous other objects and advantages of the present invention will become apparent from a consideration of the following detailed description taken in connection wlth the accompanying drawings forming a part of this specification with the understanding, however, that the invention is not'confined to any strict conformity with the showing of the drawings but may be changedor modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings:

Fig. 1 shows a vertical longitudinal section through the structure embodying the present invention.

Fig. 2 is a front elevation of the refrigerating fluid containing unit. 1

Fig. 3 is a top plan view of the fluid containing unit.

Referring now to the drawings more in detail wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 indicates generally the structure embodying this invention. As shown, the same comprises a cabinet 2 having transverse horizontal partitions 3 and 4 dividing the same into upper, intermediate and lower compartments 5, 6 and 7 respectively.

The upper part of the back wall of the cabinet is provided with the louvre 8 to permit passage of air thereinto and into the pipe 9, leading to the blower fan 10, which fan is run by a motor 11, the speed of which may be varied through manipulation of the controlling rheostat 12. The air current created by the fan 10 is discharged through an open- 1927. Serial N0. 187,076.

ing 13 cut in the partition 3, into the intermediate compartment or chamber 6.

Within the chamber 6 there is placed a cooling unit indicated as a whole by the numeral 14, which unit is of substantially L- shaped cross sectional design and comprises a closed tank 15 having a plurality of air tubes 16 incorporated therein and extending vertically therethrough. In the upper portion of the tank 15 a header 17 is positioned which has attached thereto a number of coolin coils 18. Through the header 17 and coils 18 a refrigerant circulates which circulation is maintained by a cooler and compressor 19 located in the lower compartment and from which the pipes 20 lead to the header 17, as shown. Since the compressor 19 forms no part, in itself, of the present in vention and any suitable type may be employed, no detailed description thereof will be given.

The front portion of the unit 14 may be provided with a tray or stand 21 upon which articles of food may be placed if desired and beneath the unit is located a tray 22 to receive foreign matter which might enter the tubes of the unit.

The front wall of the cabinet 2 is provided with a door 23 provided with the louvre 24 over which, upon the inside, a cover 25 may be placed when it is desired to stop the flow of cool air from the structure.

In the top of the unit 14 an expansion tube 26 is mounted into which the fluid of the tank 15 can rise when the same warms. In order to purify the air passing through the pipe 9, the tubes 16, and out of the louvre 24, an ozonizing device 27-of any desired construction may be fitted in the inlet pipe 9 to act on the air passing therethrough.

The front of the upstanding portion of the tank 15 extends upwardly to engage the underside of the partition 3 as indicated at 28 and by reason of this the air passing through the inlet opening 13 will be forced to travel downwardly through the tubes 16 in the rear portion of the tank before it can flow upwardly through the tubes in the front of the tank and out through the louvre 24.

It is apparent from the description of the invention as above given that the forced circulation of air through the air tubes 16 will cause the temperature of the room in which the device is located to drop very rapidly. Furthermore, circulation of the air through the cooling unit will tend to dpurify the same, since all germs, bacteria, an other such foreign matter in the air will, when cooled, cling to the sides of the tubes. This accumulation of germs and the like may, from time to time, be removed and taken out in the pan 22.

Having thus described my invention, what I claim is: r

1. In combination, a cabinet having an upper, an intermediate and a lower compartment, a cooling unit in said intermediate compartment having means to permit air to flow therethrough, an air circulating struc-' ture in said upper compartment designed to force air downwardly through said unit, cool air escape means opening from said intermediate compartment, and means in said lower compartment for supplying a refrigerant to said unit.

2. In combination, a cabinet having an upper, an intermediate and a lower compartment, a cooling unit in said intermediate compartment having means to permit air to flow therethrough, an air circulating structure in said upper compartment designed to force air downwardly through said unit, cool air escape means opening from said intermediate compartment, and means in said lower compartment for supplying a refrigerant to said unit, a door leading into said intermediate compartment, and means to provide an article support upon said unit.

3. An air cooling structure comprising a liquid refrigerating unit of substantially L- shaped cross sectional design, tubular bodies surrounded by the liquid of said unit, means for driving air thru said bodies for cooling, means whereby air Will be caused to travel downwardly in the longer portion of the unit and upwardly thru the shorter portion of the ,unit, and means to provide an article support upon said shorter portion. p

In testimony whereof I affix my signature.
