Abstract
A sauna device includes a chamber made of an air-proof material. The chamber is assembled inside and supported with a flexible and collapsible support frame and provided with a vertical zipper at the front side for pulling open and close, having a through hole in the top side. A heating unit is placed in the chamber, having two heaters respectively fixed at the opposite ends of a telescopic bottom base. A PTC heating member is installed in the interior of each heater and an electric fan is positioned behind the heating member. Thus, when the wind produced by the electric fan blows through the heating member, the hot air produced in the chamber will be agitated to form up-and-down convection and evenly spread all over the interior of the chamber for use.
