Abstract

La présente invention concerne un appareil de chauffage (400) comprenant : une couche interne (410), la couche interne étant composée d'une matière plastique et comprenant une première paroi d'extrémité (412), une deuxième paroi d'extrémité (414), une troisième paroi d'extrémité (416) et une quatrième paroi d'extrémité (418), la première paroi d'extrémité (412) et la deuxième paroi d'extrémité (414) étant disposées d'une manière opposée, la troisième paroi d'extrémité (416) et la quatrième paroi d'extrémité (418) étant disposées d'une manière opposée, et la troisième paroi d'extrémité (416) et la quatrième paroi d'extrémité (418) étant raccordées et disposées entre la première paroi d'extrémité (412) et la deuxième paroi d'extrémité (414) ; et un élément chauffant (420) disposé sur la troisième paroi d'extrémité (416). La matière plastique présente une meilleure plasticité qu'un matériau de mica et présente une dureté plus élevée. La fourniture de la couche interne (410) de l'appareil de chauffage devant être composée d'une matière plastique facilite la fourniture de la couche interne (410) servant de structure de support d'isolation thermique de l'élément chauffant (420) sous d'autres formes et facilite la fixation relative, et facilite en outre le montage d'autres composants structuraux par rapport à la couche interne (410) servant de structure de support d'isolation thermique de l'élément chauffant (420), ce qui permet d'améliorer considérablement l'adaptabilité de support de l'appareil de chauffage (400). L'invention concerne également un dispositif de séchage de cheveux comprenant l'appareil de chauffage (400).
