My invention is directed to apparatus for controlling central area for operation of the intake and discharge functions of the humidifier.
'through flanges 5 and securing screws or bolts and nuts represented at 6. The reservoir includes a top portion 9 which is provided with a lateral reinforcement at 8 substantially coplanar with the side wall of the plenum and contiguous with the deector 7 which proiects into the air distributing duct 1 for gathering a portion of the force flow of air therethrough and directing the force ow of air into the reservoir. The top portion 9 of the reservoir includes a channelled peripheral edge 10 which engages the upstanding edge of the reservoir 4 around which the gasket 11 fits and serves as a seat for the shaped hood 12. The shaped hood 12 is provided with a sealing channel 14 at its lower edge which engages the sealing gasket 11 which envelopes the upstanding edge 10 of the reservoir. The hood 12 is attachable to the side wall of the plenum 1 by means of screws or bolts and nuts 13 extending through flanges 12a and fastened to the marginal edges of the opening 3 in the furnace plenum 1.
The top portion 9 has a central aperture 1S therein through which the atomizing unit 16 is mounted. The atomizing unit 16 is provided with a multiplicity of spaced block supports 17, 13, 19 and 20, each including resilient mounts 17a, 18a, 19a and 20a which are mounted adjacent ribs 17h, 18b, 190 and 20h disposed radially beneath the annular downturned rim 21 of the atomizing unit. The rim 21 is integrally molded as part of the depending cylindrical housing 22 of the atomizing unit, drain apertures 22a and 22b being provided in the base of the housing. The depending cylindrical housing 22 includes inwardly extending pedestals or ribs indicated more clearly in Figl 5 at 23, 24, 2S and 26 molded internally with the housing 22 with the aid of recessed core apertures, indicated in Fig. 4 at 23a, 24a, 25a and 26a. The pedestals or ribs 23-26 serve as peripheral seats for the motor mounting plate 27 which contains radially eX- tending lugs 27a, 27 b, 27e and 27d, shown more clearly in Fig. 2, disposed in radial alignment with the pedestals or ribs 23, 24, 25 and 26 secured by means of bolts and cap screws 231), 24h, 25h and 26b in a position peripherally spaced from the interior wall of the depending cylindrical housing 22. The bolts 23h-26h have their heads molded within the pedestals 2.3-26 and have their threaded ends extending upwardly through the lugs 27a-27d and engaged by removable cap screws. The motor mounting plate 27 has a central aperture 27f therein through which the hub 30 and shaft 31 of the driving motor 28 extends. The driving motor is secured to plate 27 by means of bolts 29. The motor mounting plate 27 is provided with a central seat 27e which insures a solid support for the motor. The outer portion of the motor mounting plate 27 terminates in a downwardly depending skirt 27g which forms a mounting means for the resilient skirt 55 on atomizer screen S4 which extends downwardly in the housing formed between motor mounting plate 27 and the bottom of the cylindrical housing 22.
The depending shaft 31 is provided with a key way 31a by means of which the rotor 32 is secured to shaft 31. The rotor 32 is molded from plastic and has a central bore 33 extending therethrough for receiving shaft 31, the bore 33 being formed in hub 34 which is disposed immediately below a frusto-conical portion or inclined face 35 of rotor 32 which connects with the flat circular disc 42 of the rotor. There are passages 36 formed in the hub 34 for the passage of narrow needle-like columns of water which are pumped from the reservoir 4 beneath the atomizer unit. Disc 42 is adjusted in its position on shaft 31 by set screw 37 which extends through hub 34 on an angle that is accessible from a position beneath the rotor for adjustment of disc 42 to enable the disc 42 to be centered within the housing formed between the bottom of cylindrical housing 22 and the motor mounting plate 27. Fluid is picked up from reservoir 4 by means of depending central tube 38 whose lower teminus is shown more clearly in Figs. 10-13 as including an intake orifice 39 containing an intake aperture 40 associated with an inclined guide wall 41. When the terminus of the tube 38 containing the pickup intake orifice 39 is revolved at high speed by driving motor 28 the fluid is skimmed from the pool of uid 46 and by centrifugal action of the inclined guide wall 41, the column of fluid is lifted through tube 38 and forced in columns through passages 36 where it is distributed by disc 42 for subsequent atomization. The disc 42 is provided with blades 43 on the lower surface thereof which operate as a centrifugal pump for extracting a portion of the air flowing through the furnace plenum 1. The blades 43 are arranged on disc 42 in such positions that they coact with the central aperture 44 in the bottom of the depending cylindrical housing 22 for drawing the air from plenum 1 through the lter shown at 63 and over the confining partition wall 45 of reservoir 4 and through the central aperture 44 for distribution through the atomizer screen 54, and through the annular passages 56 between the upper wall of the depending cylindrical housing 22 and the peripheral edge of the motor mounting plate 27 and in a path beneath hood 12 through aperture 3 where it is returned to the force ow of air in plenum 1. The air as it is force owed in the plenum 1 through the central aperture 44 passes over the surface of the fluid 46 in reservoir 4, and picks up moisture therefrom.
The level of the uid 46 in reservoir 4 is regulated by oat valve 47 carried on angularly movable float valve arm 48 for controlling valve 49 connected to fluid supply 50, leading to pipe line S1 to shut-oil valve 52. A suitable overflow 53 is provided in one side of the reservoir 4. A drain connection 57 is provided in the bottom of reservoir 4 connected to drain pipe 58 in which there may be a shut-ott valve S9, as shown in Fig. 19. The power circuit shown at 60 may be connected in various ways through the humidistat 61 to the furnistat 62 from which circuit connections 28a extend to the driving motor 28. Thus the motor is energized whenever conditions call for increased moisture and the driving motor 28 is initiated in operation, pumping moist air through aperture 44 and pumping liquid through depending tube 38 from the liuid 46 in reservoir 4 where it is atomized by being sprayed in a thin film which moves up inclined wall 35 and -s distributed in a thin iilm along the surface of ilat disc 42 where it is spattered against the atomizer screen S4 in droplets which are broken down into a fine mist which is force flowed through passages 56 under the hood 12 and returned through aperture 3 to the plenum 1 where it mixes with the balance of the air being force flowed through plenum 1.
The air which is force flowed through plenum 1 is heated and is forced under pressure through the vertically extending duct indicated in Fig. 18. Only a portion of the heated air which is owing at high velocity through the plenum 1 is skimmed off from the main body 'of the air owing through plenum 1 for treatment by the humidifier of my invention. This portion of the air after humidication is returned to the main body of the air in plenum 1 at a location displaced from the position at which the air is treated from the plenum 1 in the direction of the flow of the air through plenum 1.
A lter 63 is interposed between the air intake to the humidifier and the air passage between the upper edge of the confining partition wall 45 and the aperture 44 leading to the atomizer unit. The filter 63 is constructed in the form of a slide which operates in a guide 64 which enables the filter to be readily removed and renewed from time to time.
The driving motor 28 may be connected in a variety of ways to the humidistat through the furnistat and the diagram shown in Fig. 19 is merely representative of one of several different arrangements and is to be considered in the illustrative sense and not in the limiting sense.
