Abstract
Abstract A humidifier which opens a solenoid valve when the blower fan of a central heating system is energized, and which valve is closed upon opening the circuit to the blower fan, or is controlled by a humidistat while the blower fan is operating. A particularly salient feature of the device is that the body of the solenoid valve is constructed of non-metallic material, such as plastic, which will not corrode nor cause electrolysis between adjacent connections, which will greatly reduce the accumulation of residual mineral scale. The valve body, which is provided with a quick removable filter, is small in size and has a relatively large filtration capacity, before it has to be replaced. Furthermore, the valve body is molded of plastic in a single unit, which plastic may be Nylon, Velox, or Acetal or plastics having similar characteristics. The valve body is so constructed that a single spray nozzle can be used therewith, and the ''''drip, '''' if any, conveyed to a suitable place of disposal, or, an adapter unit may be used to employ two or three spray nozzles, with a collector lip to direct residual drip, if any, into a drainage system and to a point of disposal.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
244 words
In combination with a central heating system having a furnace with ducts leading therefrom; a. a water inlet supply conduit leading from a source of water under pressure, b. a solenoid actuated valve, the body of which is made of plastic, mounted on the outlet duct leading from the furnace, which valve is in fluid communication with the water inlet supply conduit, 1. said solenoid actuated valve having the discharge thereof in position to discharge water into the duct leading from the furnace, 2. at least one plastic nozzle connected in fluid communication with said discharge of said solenoid valve to atmoize water which is discharged into the duct leading from the furnace, 3. a moisture receiving tray mounted on said valve body and positioned near the discharge end of said nozzle, 4. said moisture receiving tray having a passage formed therein, which passage leads therefrom to convey moisture from said tray, 5. a solenoid mounted on said solenoid actuated valve, 6. an armature within said solenoid of said solenoid actuated valve and extending into said valve, 7. a valve seat on said solenoid armature, 8. said plastic body of said solenoid actuated valve having passages formed therein to direct water from said water inlet supply conduit to said valve seat on said armature, 9. a complementary valve seat in said valve body surrounding the water discharge of said body, so when said valve seat is in open position, water will be directed therethrough.
