摘要

A device for reusing warm air after its initial use in an opticians. The air is drawn back through a double skinned tubular channel, and the suction arises from a tubular diminishing in front of or behind the heat source. An energy saving hot air stream is produced through a regulating coupling. Cold air is sucked through a ventilator (2) and fed to an electric heater (3) in the turbulence chamber (4) in order to heat the spectacle frames (5). USE/ADVANTAGE - Energy saving with no heat loss.
