Abstract
Abstract An apparatus is set forth for humidification of a dwelling wherein a transparent housing includes a valve operative through a solenoid with a flexible input water line directed into the valve and a flexible output line directed from the valve to a spray head. The valve is associated with a humidistat to effect operation of the valve to inject water vapor into a stream of air directed within a central duct work of a furnace arrangement. The spray head includes a horizontal and vertical pivot mount in association with the water input line to enable selective positioning of the nozzle at a desired rotation relative to the air stream within the duct work. Modifications of the instant invention include removable and selectively cleansable sponge coverings for the spray nozzle head.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
172 words
A humidifier apparatus in combination with a forced air duct, and a fan means operably associated with the duct to direct forced air therethrough, the apparatus comprising, a housing enclosure including a solenoid valve fixedly mounted therein, and a humidistat mounted exteriorly of the housing enclosure for opening the valve upon sensing of a predetermined relative humidity, and the humidistat means further electrically associated with the fan to actuate the fan upon simultaneous opening of the solenoid valve, and a fluid input conduit directing fluid to the solenoid valve, and an output conduit directing fluid from the solenoid valve, and a nozzle means mounted in the duct coupled to the output conduit remote from the solenoid valve, and wherein the input conduit and the output conduit are each flexible to enable repositioning of the housing closure relative to the duct, and wherein the housing enclosure is transparent, and wherein the duct includes a transparent access door positioned adjacent the nozzle means to enable visual observation of the nozzle means and access thereof.
Claim 2
Dependent Claim
172 words
A humidifier apparatus in combination with a forced air duct, and a fan means operably associated with the duct to direct forced air therethrough, the apparatus comprising, a housing enclosure including a solenoid valve fixedly mounted therein, and a humidistat mounted exteriorly of the housing enclosure for opening the valve upon sensing of a predetermined relative humidity, and the humidistat means further electrically associated with the fan to actuate the fan upon simultaneous opening of the solenoid valve, and a fluid input conduit directing fluid to the solenoid valve, and an output conduit directing fluid from the solenoid valve, and a nozzle means mounted in the duct coupled to the output conduit remote from the solenoid valve, and wherein the input conduit and the output conduit are each flexible to enable repositioning of the housing closure relative to the duct, and wherein the housing enclosure is transparent, and wherein the duct includes a transparent access door positioned adjacent the nozzle means to enable visual observation of the nozzle means and access thereof.
Claim 3
Dependent Claim
60 words
A humidifier apparatus as set forth in claim 1 wherein the nozzle means includes a rigid further output conduit securing the nozzle means to the output conduit, and the nozzle means includes a cylindrical spray conduit, and an ellipsoidal spray head axially aligned with the spray conduit mounted thereon, and the spray conduit is adjustably mounted to the rigid conduit.
Claim 4
Dependent Claim
88 words
A humidifier apparatus as set forth in claim 2 wherein the spray conduit is adjustably mounted to the rigid conduit utilizing a first vertical rotatable pipe mounted to the rigid conduit, the first vertical rotatable pipe is in fluid communication with the rigid conduit at one end and to a directional box at the other end, and further including a horizontal rotatable pipe horizontally mounted to the directional box to enable rotation of the directional box and the horizontal rotatable pipe relative to the first vertically rotatable pipe.
Claim 5
Dependent Claim
31 words
A humidifier apparatus as set forth in claim 3 further including an on/off switch mounted to the housing enclosure, wherein the on/off switch electrically disengages the solenoid valve to the humidistat.
Claim 6
Dependent Claim
40 words
A humidifier apparatus as set forth in claim 4 including an in-line filter mounted between the solenoid valve and the input conduit, wherein the in-line filter is replaceably mounted relative to the solenoid valve to enable servicing and replacement thereof.
Claim 7
Dependent Claim
56 words
A humidifier apparatus as set forth in claim 5 including a spray head cover selectively mounted encompassing the spray head, the spray head cover defined by an elongate cylindrical cavity, wherein the cylindrical cavity includes an entrance opening, and the entrance opening includes a resilient perimeter thereabout to engage the spray conduit adjacent the spray head.
Claim 8
Dependent Claim
69 words
A humidifier apparatus as set forth in claim 6 wherein the spray head cover is formed of a sponge-like material, and includes a planar fan-like rib extending orthogonally relative to the spray head cover and aligned parallel to an axis defined by the cylindrical cavity, and further including a plurality of ribs extending from the cylindrical cavity through the fan-like rib to maintain geometric integrity of the fan-like rib.
