Abstract
Abstract An improved dehumidifier which is of very simple type for removing moisture out of a room''s air; the device consisting of a tank filled with water that is mixed with a commercially prepared anti-freeze solution such as Prestone, a tubular coil made of aluminum being submerged in the tank liquid, one end of the coil being connected to an external air outlet box, whereby the liquid is maintained cool so that room air moving through the coil is cooled so that its moisture content is dropped; the moisture running out of a drain pipe connected to the coil.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
223 words
A dehumidifier device comprising in combination: a liquid containable vessel having an aperture in a lower portion therof and having an opening in an upperportion thereof adapted to have liquid and ice introduced therethrough into the liquid containable vessel; a tubular conduit structure having an air inlet at one end thereof and an air outlet at an opposite end thereof, mounted with the inlet and outlet substantially exterior to inner space defined within the liquid containable vessel and having a predetermined major proportion of the tubular conduit structure extending through the inner space positioned to be below liquid level when liquid is within the liquid containable vessel, a drain hole being defined in a lower wall of a portion of the tubular conduit structure positioned at a substantially lowest level relative to other portions of the tubular conduit structure such that condensed water within the tubular conduit structure is gravity-drainable through the drain hole; a drain conduit means for sealably mating at an upper open end thereof within said drain hole and the drain conduit means being further for extending sealably through said aperture of the liquid containable vessel such that condensed water is drainable therethrough to an exterior of the liQuid containable vessel from within the tubular conduit structure; and an aluminum lining within said inner space lining said liquid containable vessel.
Claim 2
Dependent Claim
223 words
A dehumidifier device comprising in combination: a liquid containable vessel having an aperture in a lower portion therof and having an opening in an upperportion thereof adapted to have liquid and ice introduced therethrough into the liquid containable vessel; a tubular conduit structure having an air inlet at one end thereof and an air outlet at an opposite end thereof, mounted with the inlet and outlet substantially exterior to inner space defined within the liquid containable vessel and having a predetermined major proportion of the tubular conduit structure extending through the inner space positioned to be below liquid level when liquid is within the liquid containable vessel, a drain hole being defined in a lower wall of a portion of the tubular conduit structure positioned at a substantially lowest level relative to other portions of the tubular conduit structure such that condensed water within the tubular conduit structure is gravity-drainable through the drain hole; a drain conduit means for sealably mating at an upper open end thereof within said drain hole and the drain conduit means being further for extending sealably through said aperture of the liquid containable vessel such that condensed water is drainable therethrough to an exterior of the liQuid containable vessel from within the tubular conduit structure; and an aluminum lining within said inner space lining said liquid containable vessel.
Claim 3
Dependent Claim
36 words
A dehumidifier device of claim 1, including a coolant media within said inner space at a level such that the tubular conduit structure is immersed with said major proportion below liquid level of the coolant media.
Claim 4
Dependent Claim
105 words
A dehumidifier device of claim 2, in which said drain conduit means includes threaded structure defining said upper open end, the threaded structure being threadedly mateable to structure of and defining said drain hole and being in a mated state, the drain conduit means further including an enlarged portion located within said inner space and being of predetermined largeness larger than outer dimensions of said aperture such that the enlarged portion is sealably seatable within said aperture when drawn downwardly thereinto, and the drain conduit means further including a clamping structure and element for tightening downwardly the enlarged portion sealably to seat within said aperture.
Claim 5
Dependent Claim
57 words
A dehumidifier device of claim 2 in which the clamping structure and element include respectively male threads on a portion of drain outlet structure defining a drain outlet of the drain conduit means, and a threaded nut element tightened onto said male threads such that the enlarged portion is drawn sealably against vessel structure defining said aperture.
Claim 6
Dependent Claim
18 words
A dehumidifier device of claim 4, in which said coolant media includes ice in ethylene glycol and water.
Claim 7
Dependent Claim
25 words
A dehumidifier device of claim 5, including a blower means for pumping air to be edhumidified into the air inlet of the tubular conduit structure.
Claim 8
Dependent Claim
35 words
A dehumidifier device of claim 1, in which said tubular conduit means comprises as a major proportion thereof a thin polyethylene tube and pulsating means for the polyethylene tube to squirm within said inner space.
Claim 9
Dependent Claim
61 words
A dehumidifier device of claim 7, including an adjacent tank compartment containing a raised screen mesh upon which a continuation portion of said tubular conduit means extends, and a quantity of solid calcium chloride upon said screen mesh, and a drain outlet port defined in a bottom of the adjacent tank compartment positioned for drainage of liquid and dissolved calcium chloride.
