1 Claim.
My invention has relation to improvements in air conditioning apparatus and consists in the novel featuresof construction more fully set forth in the specification and pointed out in the claim.
The principal object of the invention is to provide a compact unitary devicefor cooling or heating and circulating the air within a room so as to either lower or raise the temperature of said room air.
It is a further object of the invention to provide such a device that may be manufactured at low cost and that may be readily moved from room to room as desired.
These advantages, as well as others inherent in the invention, will be better apparent from a detailed description thereof in connection with the accompanying drawings, in which:
Figure 1 is'a side elevation of my improved air conditioning apparatus; Fig. 2 is an end elevation looking toward the open end from which the air discharges; Fig. 3 is a vertical transverse section taken on the line 3-3 of Fig. 1; Fig. 4 is a vertical longitudinal section through the apparatus taken on the line 4-4 of Fig. 2; Fig. 5 is a vertical cross 25 section taken on the line 5-5 of Fig. 1; Fig. 6 is a side elevation of a fragment of the apparatus showing a filter applied to the air inlet duct; and Fig. 7' is a longitudinal sectional detail taken on the line '!--1 of-Flg. 6.
Referring to the drawings, i represents a cylin drical casing supported by feet 2, 2 on a suitable 'base 3 on which a motor M is also mounted. concentrically disposed within the casing I there is a tube 4 of smaller diameter so as to leave an annular space S between said tube 4 and the casing l. The tube 4 stops short of a closure plate 5 disposed over the end of casing I adjacent to motorM so as to provide a space S for a fan F securely fixed on the motor shaft 6. The blades I of the fan are flat but have their outer edges 8 and inner edges 8 arcuate so as to follow the contour of the casing l and tube 4, respectively. It will be observed (Figs. 1 and 4) that the inner edges 9 of the blades slightly overlap the adjacent end of tube 4, and the blades are pitched so that upon being rotated in the proper direction, they will force air through the space S toward the open end thereof. The tube 4 is supported within the casing l by a plurality (four in the present instance) of ducts l flied at their inner ends in the wall of tube 4 and at their outer ends in the casing I. The side of each duct toward the .fan F'is V-shaped soas to offer a minimum of resistance to the air that is forced through the I casing by the fan F. A cylindrical member ll 1931, Serial No. 144,784
fits snugly within the tube 4 and is of a length so that it extends from the inner edges of the ducts III to an annularflange [2 formed on the inner end of tube 4. Member I I has a diametrically disposed partition l3 running through it from end to end and a semicircular end wall l4 between said partition and the periphery of said member II.
The partition l3 and end wall l4 form a container within the member II in which ice I, or other cooling medium, may be held. A cover plate 15 is provided for said container, between which and a cover plate l6 for the tube 4 there is disposed a coil spring IT to take up any play between the parts so as to eliminate vibration when the motor M and fan F are operating. When the apparatus is used as an air cooler, the ice container formed within the member II is disposed at the top of the tube 4; but if it is desired to use-the apparatus as an air heater,- this container-may be inverted and a suitable heating element (not shown) disposed either within it or on the partition I3,
The operation of my improved air conditioning apparatus is as follows:
We will assume that the container of the member H is charged with ice so that the apparatus may be used as an air circulating device. The motor M'is now started so as to rapidly rotate the fan F, the blades of which will force air outward ly through the space S into the room and draw the room air through the ducts l0 into the member ll below the partition l3. As the air travels through the member II, it will, of course, be cooled by contact with the cool surfaces of the member ll through which the air is moved by the action of the fan F. Thus, we have a continuous circulation of air through the ducts Hl, through the member II, and back through the space S within the casing I from which the cooled air is discharged into the room.
The cover plate is removable, for which purpose I provide a radially disposed tapering opening l8 leading from the center thereof to the periphery of the plate 5. This opening l8 permits the cover plate to be disposed over the shaft 6 of the motor, after which a sliding gate i 9 may be slipped into the opening and held in place by guide lugs 20, III, as well understood in the art.
A plurality of spring clips 2|, 2| may be secured adjacent to the inner end of the casing l for the purpose ot engaging and holding in place the cover plate 5.
' Referring to Figs. 6 and '1, 22 is an air perviousv screen held in place on the end or the duct II tube being closed and having air inlet ducts leading through the casing wall, an air conditioning device removably disposed within said tube, and a fan in the space between the tube and the closed end of the casing, said fan having blade-s operating between the cylindrical walls of the casing and of the tube.
