The present application is a division of my copending application, Serial No. 432,014, filed February 23, 1942, now Patent No. 2,390,104 granted February 4, 1945.
In cabinets in which ice is used for cooling or deliquescent chemicals for dehydrating air, or both, it is desirable to dampen the drip and splash to have quiet operation. Also, where such cabinets are moved around in a room or used in moving conveyances, it is advisable that some precaution be taken to prevent spilling and splashing of the waste water and waste chemical solution. Furthermore, evaporation of waste stored water into the air stream should be prevented.
According to the present invention splash prevention, drip noises and evaporation of waste water have all been effectively controlled through improvements in waste tank construction in which the surface is substantially sealed from the air stream and a floating raft is employed to prevent splash. A screen carried by the raft reduces splash and drip noises.
Thus one object of the present invention is to provide a portable cabinet of the type described in which a waste tank is provided with splash preventing means.
Another object is to provide an improved waste tank or device of the character described in which the air stream is substantially sealed from the surface of the waste tank to reduce evaporation to a minimum.
Another object is to provide a portable cabinet of the type developed in which drip and splash noises have been materially reduced.
These and other objects and advantages residing in the combination, construction and arrangement of parts will be more fully understood from a consideration of the following specification and claims.
In the drawing,
Fig. 1 is a vertical section through the cabinet and its interior structure,
Fig. 2 is a sectional view taken on line II-II of Fig. 1, and
Fig. 3 is a sectional view taken on line III-III of Fig. 1.
In the illustrated embodiment, the portable cabinet It) has an opening l2 in the bottom l4 for the upward flow of air around the waste tank H5. The air passes between perforated trays l8 and into indirect contact with the ice in the ice container 20 and with the chemical dehydrant in the dehydrating case 22. For a more specific disclosure of the air flow, reference is made to my aforesaid copending application.
Ice water from the ice container 20 drips through openings 24 upon the trays l8 and is cascaded from one tray to the next through openings 26. From the lowest tray ill the waste ice water is discharged upon the cover plate 28 which extends over the entire tank I6. Holes 30 in the plate 28 permit the waste ice water to drip through to engage, without appreciable drip or splash noises, with the close meshed screen 32 supported on the floating raft 34. Brackets 36 limit the upward movement of the raft 34. The level in the tank [6 is maintained'at this same height by the overflow pipe 38. Openings in the raft 34 are indicated at 40 and 42 and permit the waste ice water to pass through the raft and into the overflow 38.
Waste chemical solution from the dehydrator case 22 drips upon the screen 44 located beneath the case 22 and supported upon the plate 28. The screen 44 reduces drip and splash noises in the same manner on the screen 32.
Casters 46 support the cabinet 10 for movement. The raft 34 floated upon the surface of the tank IE will permit such movement without fear of splashing the contents of the tank. Similar results will be obtained when the unit 10 is installed in moving vehicles, such as trucks, buses, trains and the like. In practice, accumulation of waste in the tank "5 will be drawn out the drain 48 from time to time to avoid use of the overflow 38.
1. An air conditioning apparatus of portable construction and adapted to be moved about while in service, comprising an air conditioningunit, a waste tank supported as a unit in the apparatus and movable therewith, a discharge for waste liquid flowing by gravity from said air conditioning unit, an intake in said tank for waste liquid from said discharge, and an anti-splash and silencing means located in said tank in vertical alignment with said discharge and said intake to silence the liquid discharged in said tank and to minimize splashing of waste liquid in said tank outwardly through such intake, against the normal flow of discharge liquid, upon movement of said apparatus in service.
2. An air conditioning apparatus as defined'in claim 1 in which said anti-splash and silencing means takes the form of a floating raft approximating the. surface area of waste liquid in said tan y 3.-An air conditioning apparatus, portable in construction to permit moving it about while in service, comprising an air conditioning unit, a
waste liquid cascading structure below said unit, a
Waste tank below said cascading structure of open type construction; a floating raft in said tank, approximating surface area of the liquid therein to substantially'separate the surface of the liquid from any air stream between said tank and said cascading structure.
