  • Capacitance switches change the capacitance depending on the contact area of the finger, so the change in capacitance increases by touching the finger firmly, but if you touch it lightly or touch the end of the capacitance switch, The change in capacitance is small. Further, in the capacitance switch, when a conductor such as water is touched, the capacitance changes in the same manner as when touched with a finger.

Conversely, if the threshold value is set low, it is erroneously detected that a finger touches when a large water droplet adheres. In addition, large water droplets that travel through the main body are removed in a short time without staying on the capacitance switch. Therefore, when a change exceeding the threshold value continues for a certain period of time, detection is performed to prevent false detection. However, it is necessary to touch the capacitance switch for a certain period of time during operation.

  • the configuration having the front side detection sensor 8a and the rear side detection sensor 8b is taken as an example, but a configuration having only one of them may be used.
  • the hand dryer according to the present invention is useful in that it can accurately detect a change in capacitance that occurs when the user operates the operation unit.

Abstract

La présente invention concerne un sèche-mains (1) présentant : une unité de ventilation (2) permettant de générer un flux d'air et positionnée à l'intérieur d'un logement (10) dans lequel des orifices de ventilation (5a, 5b) sont formés, lesquels se raccordent à une section d'insertion de main (9) dans laquelle il est possible pour un utilisateur d'insérer une main ; et un capteur de détection (8) permettant de détecter que la main d'un utilisateur a été insérée dans la section d'insertion de main (9). En outre, lorsque le capteur de détection (8) détecte la main d'un utilisateur, le flux d'air produit par l'unité de ventilation (2) est injecté dans la section d'insertion de main (9). Le sèche-mains (1) est en outre équipé : d'un panneau avant (11) prévu de façon à pouvoir être fixé à et être détaché de la surface avant du logement (10), et pourvu d'une unité de fonctionnement (12) permettant de modifier les réglages de dispositif ; d'un support (16) prévu dans une position située sur la surface arrière du panneau avant (11) et correspondant à l'unité de fonctionnement ; d'une électrode (14) permettant de détecter un changement dans la capacité produite lorsque l'unité de fonctionnement (12) est actionnée ; et d'une unité de commande (30) permettant de commander un moteur de ventilation en fonction des modifications de la capacité produite dans l'électrode (14). En outre, le support (16) retient l'électrode (14) de façon à ce que l'électrode (14) entre en contact avec la surface arrière du panneau avant (11).
