The present invention relates to an electric radiator. A heating body, made of a resistive element embedded in a light alloy unit, is housed in an enclosure. The enclosure and heating body are separated by stiffening elements to surround the heating body with an air space. Heat is controlled by cutting power to the heating body during a variable time interval. |

DETAILED DESCRIPTION OF THE INVENTION The present invention, as shown in the figures of the drawing, includes an electric heating body 1 mounted via spacers within an enclosure 2 of metal or synthetic material.
Spacers 7 define a space 3 between heating body 1 and enclosure 2, allowing for the passage of air.
Even during continuous operation of the radiator at maximum power, the temperature in enclosure 2 cannot, under any circumstances, reach a dangerous level.
As shown in FIG.
1, heating body 1 includes a shielded resistive element 4 embedded by hot molding in a light alloy metallic unit 5.
The volume of metallic unit 5 is calculated to ensure sufficient accumulation of thermal energy so that changes in temperature induced by the power cut-offs in the system control are not perceived within the heated environment.
The spacers can be, for example, stiffeners for a metallic enclosure 2, and/or tubular sections 7 (which can also serve as conduits for power supply cables).
Unlike prior art devices, the present invention controls temperature without a thermostat, and without reference to the ambient temperature.
An electronic control box 8 includes circuits which periodically cut and restore the current according to a short cycle, e.
g.
, four seconds.
Depending on the respective cut-off and restoration periods, heating body 1 receives power ranging from 0 to 100% of the nominal power.
The front surface of the box 8 includes an on-off button 9, and two push-buttons 10 and 11 which respectively progressively increase and reduce the length of the current restoration periods (and therefore the relative power).
The value of the relative power, expressed by percentage, is displayed on a small LCD screen 12.
An application of the present invention in conjunction with heating communicating doors 13, which eliminates use of bulky radiators, is shown in FIGS.
3-5.
The heating door 13 includes heating body 1 as described above in the lower part of the door.
Two vertical lateral plates 14 and side elements (e
