[57 [ABSTRACT A window type air conditioner in which moisture derived from the evaporator is conveyed to a condensercontaining chamber for disposal therein, said chamber including a wall having an inlet ring which confronts a condenser fan and around the interior surface of which ring moisture circulates during operation of the apparatus. A retaining wall impedes flow of moisture out of the inlet ring in a direction upstream of the condenser fan, and an aspirator baffie means confronts the fan and projects radially inwardly of the inlet ring to establish a reduced pressure zone on the fan side of the baffie means. Moisture circulating in the inlet ring ,flows to the outer edge of said baffie means and thence across the baffie means to an inner edge thereof from which it is discharged and entrained in the condenser cooling air stream.
6 Claims, 3 Drawing Figures BACKGROUND OF THE INVENTION In certain window type air conditioners, particularly those which use a blade-tip-supported slinger ring as the primary means for disposing of condensate, a problem has been encountered in eliminating all of the condensate and preventing splashing, or spitting, of particles of moisture out of the condenser cooling fan and thence through the air admission louvers without contacting the condenser. The problem arises from the fact that the pressure developed in the condenser plenum chamber has a tendency to force droplets of moisture back toward the fan from which it reaches the inside peripheral surface of the inlet ring portion of the fan shroud. Moisture reaching this surface may be forced back into the air flowing toward the fan, thereby interfering with complete and proper disposal of the condensate. This problem can be particularly troublesome when a machine of given construction and dimensions is modified to meet new, more demanding, design criteria. This frequently necessitates operation of thefans at higher speed with resultant forcing of water out of the slinger sump. A corresponding reduction in the rate of condensate disposal occurs.
SUMMARY OF THE INVENTION The general objective of my invention is to eliminate the above mentioned problemsby insuring complete entrainment of all of the moisturein the condenser cooling airstream thus enabling the air conditioner to run with a'drier sump. Preferably, although not necessarily, I achieve this objective by utilizing a slinger ring as a primary means, for entraining moisture, in combination with an aspirator baffle which is disposed to serve as a water elevating pump which takes any excess moisture which may be circulating within the fan inlet ring and insures entrainment thereofin the condenser air stream. This baffle structure is carried as an extension of the inlet ring and projects radially inwardly thereof toward theaxis of the fan. Preferably the baffle has two portions, one of which comprises means for lowering the pressure and raising the moisture to a free edge of said one portion. The other portion also performs this function to some extent, but is particularly useful in preventing splashing of the particles of moisture outwardly from the fan.
The apparatus is featured by being simpler, cheaper, and more effective than moisture eliminating apparatus previously used in this art. Also, rather than being spaced upstream of the inlet ring, like certain aspirators known in the art, the aspirator baffle of this invention forms a part of the shroud inlet ring and directly confronts the fan. Maintaining the baffle as close as possible to the fan blading has been found to achieve the greatest possible pressure reduction and thence to maximize the pumping and removal of excess moisture. Thus it eliminates the moisture before it can escape from the inlet ring and arrive upstream of the fan.
BRIEF DESCRIPTION OF THE DRAWING training intrumentalities contemplated by this invention; and,
FIG. 3 is a side view illustrating certain details of the fan shroud and air inlet ring.
DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT With initial reference to FIG. 1, there is diagrammatically illustrated at 10 an air conditioner of generally known type which includes an evaporator 11, a condenser l2, and evaporator and condenser fans 13 and 14, respectively, arranged to be driven by an electric motor 15 through shafting shown at 16. As is common in such apparatus there is included means which provides a sump under evaporator 11, the sump being shown in simplified form at 17 in FIG. 1. Moisture derived from the evaporator is collected in the sump, from whence it flows through a hose or pipe 18 into the condenser chamber 19 for disposal therein. It should be understood that a sump (not illustrated) would also underlie the condenser 12 and its fan 14, and that the moisture would be collected in said sump for entrainment in the stream of condenser cooling air.
As appears to good advantage in FIG. 2, the inner side of the condensenthat is the side which is presented toward the evaporator compartment 20, is covered by shroud structure 21 which forms a plenum and which is provided with an aperture within which is disposed the condenser cooling fan 14. The aperture is de- I fined by an air inlet ring 22 which protects-the fan and promotes flow of outdoor cooling air over the condenser. This air can be inletted to the machine in any suitable. manner not shown.
As the primarymeans for entraining condensate in the condenser cooling air stream, I prefer to utilize a slinger ring 23 which is of known type, has angular cross section (FIG. 3), and surrounds the periphery of FIG. 2 is a perspective view, on a larger scale, showing the condenser, its cooling fan, and the moisture enthe fan blading and is attached thereto through the agency of short extensions 24 which are formed integrally with the blades (see upper portion FIG. 2) This slinger ring dips within the moisture collectedbeneath the condenser and fan, throwing the water outwardly into position in which it is entrained in the condenser cooling air derived from fan 14. As noted above, in a system of this kind the pressure developed in the plenum tends to force moisture back from the slinger ring toward the fan from which it reaches the interior surface of the air inlet ring 22. Toprevent escape of this moisture upstream of the fan 14, I have provided the inlet ring with an inturned peripheral flange 25' (see particularly FIG. 3). This flange extends around the upstream edge of the inlet ring. By preventing escape. of the moisture which reaches the inside surface of the inlet ring 22, the apparatus promotes circulatory flow of moisture around the inside of the ring in the direction of rotation R of the fan 14. This moving moisture has been indicated in FIG. 2 by arrows bearing the reference numeral 26.
- In particular accordance with this invention, means is provided to re-entrain this moisture in the condenser cooling air and thereby to dispose of the same completely. This is accomplished by the use of a baffle which has an apex 28a and 29a, which projects radially inwardly of the ring 22. Thus each baffle portion has an upper edge which terminates in the said apex and from which edge is discharged moisture in the manner now to be described. Due to the impedance which the baffle structure presents in the air flow path, a zone of lower pressure is formed behind each baffle portion. The resultant lowered atmospheric pressure forces the water circulating downwardly within the ring 22, and toward the baffle structure, to a position in which it crosses the 1 rear surface of the baffle and is carried upwardly thereacross to the free edges which terminate in the mentioned apexes. Water breaks free from these free edges, as represented by arrows shown at 30 in the drawing, and impingement of such water on the rotating blades -of the fan 14 breaks the droplets of water into a spray which is mixed with the. air in the condenser plenum and is carried onto the condenser 12, where it is dissipated in thehot air passing through the condenser I under the action of the fan. v
It is to be noted that while the invention in its broader, aspect is not limited to baffle structure of any particular shape, it is preferred that this structure comprise the two generally triangular portions described. Also, in order to-take advantage of the natural tendency of the water to circulate downwardly around the inlet ring 22 in the direction of rotation of the fan,-it is preferred that the baffle structure be located in the lower righthand quadrant of the eye of the blower, ash is seen in. FIG. 2. Thatis, the baffle structure is located in that lower quadrant in which thewater is first caused to flowupwardly as it circulates within the inlet ring. This results in maximum benefit from the zone of low pressure developed behind the baffle and immediately ahead of the fan blade.
