<p>A new electric heater includes an air inlet (10a), an air outlet (10b), and heating elements (3) provided transversely between the left wall and the right wall of a casing (1). The front outer wall (11) of the casing (1) forms into a first safe net (113). A honeycomb shape plate (4) is provided behind the first safe net (113), and walls of the honeycomb shape small holes (41) are provided with reflecting surfaces. The heating elements (3) are provided in the heating cavity (151) formed between the reflecting plate (6) and the honeycomb plate (4). The reflecting plate (6) is disposed slantways in the heating cavity (151), the reflecting surface of the reflecting plate (6) faces to the heating elements (3) in parallel basically. The reflecting plate (6) is provided with air inlet holes (6a). Cool air out of the casing (1) enters into and rises gradually along the heating cavity (151), and is heated continuously, and is discharged from the top air outlet (10b) of the casing (1).</p> |
