Abstract
A dehumidifier uses high voltage to cause moisture to condense out of an airflow in contact with a series of needles and a screen forming the cathode and anode respectively of a diode structure. Condensate is sucked into small holes in either or both of the needles and/or the screen by a vacuum. Ultra-violet light is applied to reduce the incidence of ozone.
Claims7
An apparatus comprising:
- a case of an electrical non-conducting material, the case including a case wall for enclosing a case volume space;
- a means for enabling an air flow into the case volume space;
- a means for enabling the air flow to exit the case volume space;
- a plurality of hollow support stands extending from the case wall into the case volume space, each of the support stands providing a plurality of hollow needles extending therefrom, each of the needles providing an aperture at a terminal end thereof;
- a high voltage power supply enabled for generating a potential of tens of thousands of static volts relative to ground potential, the potential impressed onto the support stands and the needles;
- a means for providing suction to the support stands and the hollow needles for drawing air from the case volume space through the needles and the support stands so as to draw moisture therein to a sink for collection of condensed water vapor.
