Abstract (en)

The device uses a brush (1) that slides parallely to the strips that compose the grill (4.1) of the heat transfer apparatus (4). The ends of the brush (1) or some blocks (2) fixed to the brush (1), slide in some guides (3.1) composed from section bars (3). The ends of the brush (1) are fixed - directly or through some blocks (2) - to a drawing flexible element such as a belt (5) that moves in an alternate way following an eight shaped path and it slides on at least four pulleys (6, 7). One of them acts as a driving wheel and the others act as transmission gears. Every motive pulley (7) engages on the driving shaft of an electric engine (8) controlled from an electronic apparatus. This apparatus is equipped with a timer that controls its ignition and its switching off after lapses of time. It also controls the reversal of the drawing flexible element through some electronic impulses after having checked the brush (1) position. <IMAGE>
