Auto-sensing hand dryer
First Claim
1. An auto-sensing hand dryer, comprising:
- an airflow generating device for generating a hand drying airflow;
a guiding duct comprising a connection portion in communication with the airflow generating device and for obtaining the hand drying airflow, an air outlet portion communicating with the connecting portion for guiding and discharging the hand drying airflow and comprising an air discharge opening, and a housing encircling the air discharge opening and forming an internal space; and
a sensing unit disposed in the internal space and electrically connected to the airflow generating device for determining whether the airflow generating device is to generate the hand drying airflow, the sensing unit comprising a sensing region at least covering the air discharge opening.

Abstract
An auto-sensing hand dryer includes an airflow generating device, a guiding duct connected to the airflow generating device, and a sensing unit disposed in the guiding duct. The airflow generating device generates a hand drying airflow. The guiding duct includes a connecting portion communicating with the airflow generating device, an air outlet portion communicating with the connecting portion. The air outlet portion comprises an air discharge opening and a housing encircling the air discharge opening and forming an internal space. The sensing unit is disposed in the internal space and electrically connected to the airflow generating device to determine whether to generate the hand drying airflow. The sensing unit includes a sensing region at least covering the air discharge opening. When a user hand is placed at the air discharge opening, the sensing unit senses the user hand and drives the airflow generating device to generate the hand drying airflow.
