  • Patent number: 10165908
    Abstract: A hand dryer with reduced air-intake noise includes a housing, a flow-guide plate, and an air supply module. The housing includes an accommodating space and a plurality of narrow air inlets. The flow-guide plate is disposed inside the accommodating space, but the flow-guide plate is not contacted with the housing. The flow-guide plate includes a plurality of narrow air guide holes. The air supply module is disposed inside the accommodating space, and includes a blower that extracts air inside the accommodating space to generate a drying air flow after being started and an air-guide piece connected to the blower to receive the drying air flow. An interval between the narrow air inlet and the narrow air guide hole interferes with transmission of a sound wave formed by the air flowing between the narrow air inlet and the narrow air guide hole, so that generated noise can be greatly reduced.

  • Patent number: 9220382
    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.

  • Patent number: 8813383
    Abstract: A watermark-free hand dryer includes a main body, an annular air discharge portion and a water absorbing portion. The main body generates high pressure airflow. The annular air discharge portion is connected to the main body and includes at least one extending section extended from the main body and a connecting section connected to the extending section. The extending section and connecting section surround to form an annular hand drying passage to receive user's hands. The annular air discharge portion further has at least one nozzle on an air discharge surface communicating with the annular air discharge portion. The nozzle forms an air discharge angle against the air discharge surface to output the high pressure airflow towards an air discharge side. The water absorbing portion is located on the main body and relative to the air discharge side to receive the high pressure airflow output from the nozzle.

  • Patent number: 8064756
    Abstract: An airflow directing structure for hand dryers includes an airflow directing case, an air inlet, an air outlet, a heating means, an air intake means and a flow directing channel. The air intake means has a rotary axle which has one end fastened to air intake blades. The flow directing channel has an air intake passage communicating with the air inlet, a tortuous passage communicating with the air intake passage and an air exit passage with one end communicating with the tortuous passage and the other end communicating with the air outlet. The air exit passage and the air intake means are parallel in a juxtaposed manner, and located on the same side with the air intake blades and the air outlet. Thus total size of the airflow directing structure is smaller and the cost is lower, and an optimal heating speed can be achieved to improve drying efficiency.
