Abstract
Abstract A humidifier-dehumidifier device operates in combination with a water closet. The device includes a housing with a fan mounted therein. The fan blows air through water transfer means and cooling fins positioned within the housing. Control means alternatively energize the water transfer means to humidify the air, or the cooling fins to dehumidify the air. The water closet acts as a cycling water reservoir in the humidifying mode of operation and as a catch basin in the dehumidifying mode of operation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
183 words
A humidifier-dehumidifier device for cooperative operation with a flushable water reservoir, having a water inlet and outlet and means to drain and fill said water reservoir, comprising in combination: support means to support said device in combination with said water reservoir, said support means defining an air cavity above said water reservoir; an air inlet and outlet to said cavity to permit the flow of air from the surrounding atmosphere through said air cavity; air flow means to move a flow of air into and through said air cavity; water transfer means in communication with said water reservoir to transfer water from said water reservoir into said air flow to humidify said flow of air; heat exchange means, said heat exchange means having a relatively hot side and a relatively cold side, said cold side being disposed in said air flow to condense the moisture and thereby dehumidify said flow, said hot side being in communication with said reservoir; and control means to alternatively energize said water transfer means or said heat transfer means to humidify or dehumidify said flow of air respectively.
Claim 2
Dependent Claim
183 words
A humidifier-dehumidifier device for cooperative operation with a flushable water reservoir, having a water inlet and outlet and means to drain and fill said water reservoir, comprising in combination: support means to support said device in combination with said water reservoir, said support means defining an air cavity above said water reservoir; an air inlet and outlet to said cavity to permit the flow of air from the surrounding atmosphere through said air cavity; air flow means to move a flow of air into and through said air cavity; water transfer means in communication with said water reservoir to transfer water from said water reservoir into said air flow to humidify said flow of air; heat exchange means, said heat exchange means having a relatively hot side and a relatively cold side, said cold side being disposed in said air flow to condense the moisture and thereby dehumidify said flow, said hot side being in communication with said reservoir; and control means to alternatively energize said water transfer means or said heat transfer means to humidify or dehumidify said flow of air respectively.
