Abstract: The present invention relates to a dryer having a drying chamber integrated with a condensing chamber, which dries an to-be-dried object using the heat source of a heat pump, a microwave, and a high frequency in a vacuum environment caused by a vacuum pump. The dryer comprises: a vacuum chamber having a cylindrical baffle of which the top has an opened path, having the microwave connected to the upper side thereof, having the vacuum pump connected to the rear side thereof, and having a draining unit connected to the lower side thereof; a to-be-dried object loading plate installed in the drying chamber of the vacuum chamber; the heat pump having an evaporator installed in the condensing chamber of the vacuum chamber, having a condenser installed on the bottom surface of the to-be-dried-object loading plate, and having a compressor and an expansion valve connected to the evaporator and the condenser and installed below the vacuum chamber; and a controller installed between the vacuum chamber and the heat pump, wherein the cylindrical baffle of which the top has an opened path allows the inside thereof to be formed into the drying chamber and allows the outside thereof in the vacuum chamber to be formed into the condensing chamber. According to the present invention, the to-be-dried object is simultaneously dried and condensed in the vacuum chamber having the drying chamber and the condensing chamber integrally formed therein, thereby improving efficiency in drying the to-be-dried object.
