Le sèche-mains comprend en outre : une unité de stockage d'eau disposée au-dessous de l'orifice d'évacuation (4) ; un chemin d'échappement (12) pour évacuer le flux d'air éjecté par les buses (5) à la partie de séchage des mains (3), le chemin d'échappement (12) étant disposé à côté de l'orifice d'évacuation (4) ; et un orifice d'échappement (17) disposé à l'extrémité aval du chemin d'échappement (12). Deux surfaces de paroi interne, qui sont des surfaces de paroi interne du boîtier (1) entourant la partie de séchage des mains (3) et qui se font face sur la partie de séchage des mains (3) dans le sens avant-arrière du boîtier (1), sont séparées dans le sens avant-arrière du boîtier (1).
