HAND DRYING DEVICE
First Claim
1. A hand drying device comprising:
- a drying chamber that includes an opening, a first inner wall surface, and a second inner wall surface facing the first inner wall surface, where a hand is inserted from the opening into a space between the first inner wall surface and the second inner wall surface;
a nozzle that is arranged on the first inner wall surface and is configured to blow an air stream toward the second inner wall surface;
a supply unit that supplies an air stream to the nozzle;
a hand detection sensor that detects insertion of a hand into the drying chamber;
a control unit that operates the supply unit when insertion of a hand is detected by the hand detection sensor and stops operating the supply unit when insertion of a hand is not detected by the hand detection sensor; and
an illuminating unit that is arranged at a position on the first inner wall surface shifted from the nozzle in a direction along the first inner wall surface and is configured to emit light toward the second inner wall surface, whereina center axis of the nozzle and an optical axis of the illuminating unit intersect with each other at a proper position in the drying chamber where a hand is supposed to be inserted, wherein on the hand inserted to the drying chamber, the hand drying device is configured to notify the user that the hand is at the proper position when a position of an optical image formed by a light emitted from the illuminating unit and a position where the high-pressure air stream hits on a surface of the hand mach.

Abstract
A hand drying device includes: a drying chamber; a nozzle; a supply unit; a hand detection sensor; a control unit; and an illuminating unit. The drying chamber includes: an opening; a first inner wall surface; and a second inner wall surface facing the first inner wall surface. A hand is inserted from the opening into a space between the first inner wall surface and the second inner wall surface. The nozzle is arranged on the first inner wall surface and is configured to blow an air stream toward the second inner wall surface. A center axis of the nozzle and an optical axis of the illuminating unit intersect with each other at a proper position in the drying chamber where a hand is supposed to be inserted.
