AIRFLOW DIRECTING STRUCTURE FOR HAND DRYERS
First Claim
1. An airflow directing structure for hand dryers, comprising:
- an airflow directing case having a flow directing channel;
an air inlet and an air outlet located in the airflow directing case and communicating with the flow directing channel;
a heating means located in the airflow directing case; and
an air intake means which is located in the airflow directing case and has a rotary axle which has one end fastened to air intake blades;
wherein the flow directing channel includes an air intake passage to hold the air intake means and communicate with the air inlet, a tortuous passage to hold the heating means and communicate with the air intake passage and an air exit passage which has one end communicating with the tortuous passage and the other end communicating with the air outlet;
the air exit passage and the rotary axle being parallel with each other in a juxtaposed manner and located on a same side with the air intake blades and the air outlet.

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.
