Abstract (en)
[origin: US4801915A] A heating unit, in particular for bread toasters, with a useful heat emitting area (2) and a waste heat emitting area (12), comprising an insulating body (1) and a heat conductor wound thereon. In bread toasters the efficiency of such heating units is considered unsatisfactory, and undue heating of the housing occurs since the radiation of heat in the waste heat emitting area is not directed to the material being toasted but to the housing walls. To avoid this shortcoming, it is proposed to short-circuit the heat conductor portions (12) extending in the waste heat emitting area.
