Referring tothe drawings'for a, detailed "des'cription of the invention, "a console-type air conditioningunit 'Hl isenolosed-by-acabinet H which'restsuponthe-floor 1-3 of the room which 'istobe cooled. The cabinet "H is spaced from an outsidewall i3 and has an elbow "portionflfl which extends-'oven the window sill l'5. Thewin- (low I6 is raisedwith 'thelower edge I-I 'of' the sash secured adjacent the top edge of elbow portion 14. The elbow portion 14 of the cabinet has an-open "end 18 which provides afp'assageway-"for air from outdoors-into the interior of t'he cabinet. An insulated partition I9 divides the interior of the cabinet l-l into an'eva'porator chamber 2|) and a condenser chamber 2 l Secured'in'the' lowerportionof the evaporator compartment'ZO is a"finne'd type evaporator 22 which extends across'the-width of'the cabinet "H. An air inlet 23 and air outlet 24 are provided in evaporator compartment 20, and ablower fan 25 is'positioned in the upper portionof the chamber. The blower 25, when operating, "pulls air from the room through inlet 23, passes it over the-surfaceof evaporator "22 and 'then-disch'arges-it'into 'th'e'ro'om through outlet 24.
The condenser compartment -21 "is-provided with a Y dividing wall 1 2B which divides 4 the coinpartment into anfinlet passageway 21 and outlet passagewav 28. A circular-shaped opening 29 is provided in' the lower portion of thedividingwall 26throug'h which air is circulatd' from inlet passagewav'i'l into outlet passagewayz-s by fan 30. The fan'SOispositionedin the'lower portion of outlet passageway 28 adjacent opening 29 and in axial alignment thereto. An electric motor 3| for driving the fan is secured in inlet passageway 21 and is provided with driving shaft 32 which extends through opening 29 and to which fan 38 is secured. A motor-compressor unit 33 is secured in the lower portion of outlet passageway 28 and a finned type condenser 34 is secured in elbow portion l4. The condenser extends across the width of the cabinet II and a second dividing wall 35 is secured in elbow portion l4 in vertical alignment with dividing wall 26 so that the inlet passageway 21 and outlet passageway 28 are completed.
The motor-compressor unit 33 compresses the refrigerant within the system in the usual manner and forwards it through conduit 36 to condenser 34 where the refrigerant is cooled and condensed by air circulated over the surface of the condenser by fan 30. The air is drawn from outdoors by fan 38 through inlet passageway 21 where it passes over part of condenser 34, then is passed through opening 29 and discharged to the outdoors through outlet passageway 28. As the air circulates through outlet passageway 28 it .fiows over the motor-compressor unit 33 and through the other part of condenser 34 whereby it removes heat from both members. The refrigerant is passed from condenser 34 by capillary tube 31 to evaporator 22 where it is heated by room air circulated thereover, and then returned to the motor-compressor unit 33 by conduit 38 to complete the refrigeration cycle. The room air is circulated over the evaporator 22 by blower 25 and will be cooled and conditioned to the comfort zone. Suitable controls and switches for automatically controlling the operation of the unit may be provided but are not shown or described since such controls are well known in the art and a detailed description would complicate the drawings.
As the room air is passed over the evaporator 22, moisture in the air will condense uponthe surfaces of the evaporator. To provide means for collecting this moisture, a drip trough or tray 39 is positioned under the evaporator. The tray is generally rectangular shaped having upstanding short walls 40 and a bottom 4i which slopes downwardly toward one end having a water outlet 42 extending therethrough. Connected to the outlet 42 is a trough 43 which extends downwardly through partition I9 into inlet passageway 21 with the lower end 44 extending through opening 29 and terminating adjacent the tips of blades 45 of fan 30. The fan blades 45 are secured to collar 46 which fits on the end of shaft 32 of motor 3 I. Secured to the tips of the blades 45 is a circular rim 4'! having the inner portion thereof formed into a concave groove 48. The end 44 of trough 43 terminates within the rim 41 above the groove 48 so that water being drained from tray 39 by trough 43 will run into the groove. I i
Secured to the front wall of the cabinet II is a rectangular shaped scraper member 49 having one end provided with a semi-circular shaped projection 58 and the other endprovided with a lug which is used in fastening 'the-scraper'to the cabinet H. The scraper 49 extends into the space enclosed by rim 4! with the projection 50 fitting into groove 48 with proper clearance to allow the rim to rotate without striking the scraper. As shown in the drawings, the scraper 49 is held in an inclined relationship to therim 41 and means may be provided for changing the angle of inclination if desired.
. 4 1; Refrigerating apparatus a wise direction, the friction between surfaces of groove 48 and-the water'therein will impart a velocity to the water. As the water strikes projection of scraper 49, it will be forced from the groove by centrifugal force in the form of a fine mist and thrown forwardly and upwardly in the general direction shown by the shaded lines in Figs. 4" and 5 of the drawings. It is to be understood that the location and inclination of the scraper 49 could be changed in order to change the direction in which the mist will be thrown, and more than one scraper may be used if a wider distribution of condensate is desired. In the illustrated embodiment the water mist is thrown toward the condenser 34 and will be picked up, by the air stream from the fan 38 and becarried over the'hot surfaces of the condenser 34. As the water strikes the condenser 34 it will be evaporated and then discharged outdoors through outlet passageway 28. In this manner the condensate is effectively removed and is utilized in cooling condenser 34 since considerable heat will be removed from the condenser in evaporating the condensate.
From theforegoing it can be seen that a condensate disposal means is provided which is simple in construction and eflicient in operation. The condensate is given a very positive lift by centrifugal force so that it will reach the condenser and will not drop back and collect on the bottom of cabinet I I. By changing the position of scraper 49, good directional control of the water mist is possible. The illustrated embodiment discloses a .console type air conditioning unit but it is to beunderstood that the condensate disposalmeans could'be used in any other type of-refrigerationunit where water is to be sprayedover a. heat exchange element.
While the inventionis shown in but one form,
it will be'obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and .modifications without departing from the spirit thereof, and it is desired, therefore, that onlyusuchlimitations shall be placed thereupon as are-specifically set'forth in the appended claims.
