ABSTRACT:
A portable dehumidifier is provided which includes an upper section housing a power supply, a small thermoelectric device intermediate a cold plate and a heat sink, and a blower fan. The blower fan provides the motive force to cause the humid air to come in contact with the cold plate. The cold plate causes the water vapor to condense from the air. The condensate drips from the cold plate into a trap where it is funnelled into a lower section. The upper section is mounted atop a lower section. The lower section includes a reservoir for collection the condensed water and is provided with a drain valve, float switch and vapor barrier. The drain valve permits the reservoir to be emptied of condensate. The float switch disengages the portable dehumidifier when the reservoir becomes full of condensate. The vapor barrier prevents the condensate in the reservoir from re-evaporating back into the system. The portable dehumidifier will incorporate several safety and status features, including a tip over safety switch, which disengages the unit if tipped over and an audible alarm which engages when the reservoir is full. The size of the unit, power requirements and extreme portability permits the portable dehumidifier to be utilized in campers, mobile homes, small enclosed spaces and marine applications.
