In manufacturing a heating toilet seat (40), a heater (72) is inserted into heater holding grooves (64) in a support base material (60), a heat-transfer sheet (74) is provided to cover the heater (72) and the support base material (60), and an adhesive sheet (76) is used to bond a heater unit (70) to the upper surface (62) of the support base material (60). Then a seat body (50) is laminatingly formed on the heat-transfer sheet (74) by injection molding. The heat-transfer sheet (74) covers irregularities of the heater (72) and is flush with the upper surface (62) of the support base material (60) to provide a smooth surface. Accordingly, a fused resin smoothly flows at the time of injection molding of the heater toilet seat (40), and the heater (72) will not be displaced or moved to one side even under high injection pressure.
Pour fabriquer un siège (40) de toilette chauffant, on introduit une unité chauffante (72) dans des cannelures (64) renfermant l'unité chauffante, dans un matériau de base de support (60) et on dispose une feuille (74) de transfert thermique pour couvrir l'unité chauffante (72) et ce matériau support (60), une couche (76) adhésive permettant de fixer l'unité chauffante (70) à la surface supérieure (62) du matériau de base de support (60). Ensuite on stratifie le corps (50) du siège de toilette sur cette couche (74) de transfert thermique par moulage par injection. Cette couche (74) de transfert thermique compense les irrégularités de l'unité chauffante et affleure la surface supérieure (62) du matériau de base de support (60) pour offrir une surface lisse. Ceci permet un écoulement régulier de résine fondue lors du moulage par injection de ce siège (40) de toilette chauffant, et l'unité chauffante (72) reste en place même sous une pression d'injection élevée.
