Low power dehumidifier

Abstract

A low power dehumidifier includes a body, a desiccation element, and heat transfer elements. The desiccation element has a dehumidifying region and a recycling region. Each of the heat transfer elements has a cooling end and a heating end configured for high-temperature condensation and high-temperature heating, respectively, thereby effectively recycling waste high heat generated by the dehumidifier and reducing power consumption.
