Title:
AN ELECTRIC HEATER WHICH CAN ROTATE IN ALL ORIENTATION
Document Type and Number:
WIPO Patent Application WO/2003/058136
Kind Code:
A1
Abstract:
An electric heater which can rotate in all orientation includes an electric heater body, a synchron motor, a transmission mechanism, and a supporting rack. The transmission mechanism comprises a sector rotation axis, a ball-type connecting lever, a damping frame, and U-shaped aluminium carrier. When the synchron motor rotates, the sector rotation axis driven by the synchron motor drives rotatation of the electric heater body in right or left direction. Subjected to the ball-type connecting lever and the damping frame, the electric heater body swings up and down, thereby the electric heater can rotate in all direction in accordance with the fixed track.
