Humidifier

Claim 2

A humidifier designed and adapted to be installed for use within the confines of a hot air furnace duct comprising: a hollow shell constituting a container for a predetermined amount of water, said shell being of a size and shape to assume an air moistening position in said duct, said shell having selfcontained highly absorbent filler means in line with the path of the airstream flowing through the air passage of said duct, a float controlled water supply and level maintaining valve within the confines of the hollow container portion of said shell, and a water delivering pipeline communicatively joined to said valve, said shell embodying a flat horizontal bottom wall, longitudinal vertical sidewalls and a convex airfoil-type top wall having a rounded blunt leading edge and a reduced trailing edge, the profile of the shell being comparable in shape to the shape of an airplane wing to promote and achieve maximum air travel efficiency.

Claim 3

The humidifier defined in and according to claim 1, and wherein said top wall is provided with a highly perforated depression providing a well-like pocket of requisite depth, said filler means comprising a porous blocklike sponge and said sponge being fittingly but removably lodged in said pocket and having an exposed top surface which is flush with the contour of said top wall.

Claim 4

A humidifier designed and adapted to be installed for use within the confines of a duct which is communicatively connected with the plenum of a hot air furnace comprising: a hollow shell embodying a flat bottom wall, elongated vertical sidewalls joined with marginal edges of the bottom wall, and a convex airfoil-type top wall having a rounded blunt leading edge joined with the cooperating edge of the bottom wall and a reduced trailing edge joined with the trailing edge of the bottom wall, the profile of the shell being comparable in shape to the airfoil shape of an airplane wing in a manner to promote and achieve maximum air travel efficiency, the median portion of said top wall being provided with a relatively shallow perforated sumplike depression, said depression providing an open top pocket, a porous readily insertable and removable blocklike sponge, said sponge being fittingly but removably lodged in said pocket and having a convex exposed top surface which is contoured and substantially flush with the top surface of said top wall.

Claim 5

A humidifier designed and adapted to be installed for use within the confines of a duct which is communicatively connected with the plenum of a hot air furnace comprising: a hollow shell embodying a flat bottom wall, elongated vertical sidewalls joined with marginal edges of the bottom wall, and a convex airfoil-type top wall having a rounded blunt leading edge joined with the cooperating edge of the bottom wall and a reduced trailing edge joined with the trailing edge of the bottom wall, the profile of the shell being comparable in shape to the airfoil shape of an airplane wing in a manner to promote and achieve maximum air travel efficiency, the median portion of said top wall being provided with a relatively shallow perforated sumplike depression, said depression providing an open top pocket, a porous readily insertable and removable blocklike sponge, said sponge being fittingly but removably lodged in said pocket and having a convex exposed top surface which is contoured and substantially flush with the top surface of said top wall.

Claim 6

The humidifier defined in and according to claim 3 and wherein one sidewall is provided with pipe means with one end projecting into the interior of the container portion of the shell and the other end positioned exteriorly of the sidewall, said inward projecting end being provided with a float controlled water inlet level maintaining valve.

Claim 7

The humidifier defined in and according to claim 4 and, in combination, a valved water supply and delivery line having an end communicatively joined with the aforementioned water inlet pipe.
